You should refer to the section of this Annual Report titled “Item 3.D – Risk Factors” for a discussion of 
important factors that may cause actual results to differ materially from those expressed or implied by the 
forward-looking  statements.  As  a  result  of  these  factors,  Innate  cannot  assure  you  that  the  forward-
looking statements in this Annual Report will prove to be accurate. Furthermore, if the forward-looking 
statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties 
in  these  forward-looking  statements,  you  should  not  regard  these  statements  as  a  representation  or 
warranty  by  Innate  or  any  other  person  that  the  Company  will  achieve  its  objectives  and  plans  in  any 
specified  time  frame  or  at  all.  The  forward-looking  statements  made  herein  relate  only  to  events  or 
information  as  of  the  date  on  which  the  statements  are  made  in  this  Annual  Report.  The  Company 
undertakes no obligation to publicly update any forward-looking statements, after the date on which the 
statements are made or to reflect the occurrence of unanticipated events, whether, whether as a result of 
new information, future events or otherwise, except as required by law. 

In addition, statements that “Innate believes” and similar statements reflect its beliefs and opinions on the 
relevant subject. These statements are based upon information available to Innate Pharma as of the date of 
this Annual Report, and while the Company believes such information forms a reasonable basis for such 
statements,  such  information  may  be  limited  or  incomplete,  and  the  statements  should  not  be  read  to 
indicate that the Company has conducted an exhaustive inquiry into, or review of, all potentially available 
relevant information. These statements are inherently uncertain and investors are cautioned not to unduly 
rely upon these statements. 

You  should  read  this  Annual  Report  and  the  documents  that  the  Company  references  in  this  Annual 
Report and have filed as exhibits to this Annual Report completely and with the understanding that the 
Company's  actual  future  results,  levels  of  activity,  performance  and  events  and  circumstances  may  be 
materially  different  from  what  the  Company  expects.  The  Company  qualifies  all  of  its  forward-looking 
statements by these cautionary statements.

Unless otherwise indicated, information contained in this Annual Report concerning the industry and the 
markets in which the Company operates, including its general expectations and market position, market 
opportunity and market size estimates, is based on information from independent industry analysts, third-
party  sources  and  management  estimates.  Management  estimates  are  derived  from  publicly  available 
information  released  by  independent  industry  analysts  and  third-party  sources,  as  well  as  data  from 
internal  research,  and  are  based  on  assumptions  made  by  the  Company  based  on  such  data  and  its 
knowledge of such industry and market, which the Company believes to be reasonable. In addition, while 
the  Company  believes  the  market  opportunity  information  included  in  this  Annual  Report  is  generally 
reliable and is based on reasonable assumptions, such data involve risks and uncertainties and are subject 
to  change  based  on  various  factors,  including  those  discussed  under  the  section  of  this  Annual  Report 
titled “Item 3.D—Risk Factors.”

SUMMARY RISK FACTORS 

Investing in the Company's shares involves numerous risks, including the risks described in "Item 3.D—
Risk  Factors"  of  this  Annual  Report  on  Form  20-F.  Below  are  some  of  the  principal  risks,  any  one  of 
which could materially adversely affect the Company's business, financial condition, results of operations, 
and prospects:

• Biopharmaceutical  development  involves  a  high  degree  of  uncertainty  and  most  of  the  product 

candidates are in early stages of development.

•

•

•

•

•

•

•

•

The  scientific  evidence  to  support  the  feasibility  of  developing  product  candidates  is  both 
preliminary and limited. 

The  Company  intends  to  develop  several  of  its  product  candidates  in  combination  with  other 
therapies, which exposes it to additional risks. 

The Company is heavily dependent on the success of its current clinical-stage product candidates

The  Company  may  not  be  successful  in  its  efforts  to  develop  additional  products  that  receive 
regulatory approval and are successfully commercialized. 

The Company may encounter substantial delays in its clinical studies or may be unable to conduct 
its clinical studies on the timelines the Company expects. 

The  Company's  product  candidates  in  development  may  cause  undesirable  side  effects  or  have 
other  properties  that  could  halt  or  delay  their  clinical  development,  prevent  their  regulatory 
approval, limit their commercialization or result in other negative consequences. 

The Company faces substantial competition from companies with significantly greater resources 
and experience. 

The regulatory processes that will govern the approval of the Company’s product candidates are 
complex  and  changes  in  regulatory  requirements  could  result  in  delays  or  discontinuation  of 
development or unexpected costs in obtaining regulatory approval. 

• Any of the Company's product candidates, if approved and commercialized, may fail to achieve 
market  acceptance  by  physicians,  patients,  third-party  payors  or  the  medical  community  to  a 
degree that is necessary for commercial success. 

• A  fast  track,  breakthrough  therapy  or  other  designation  by  the  FDA,  or  equivalent  in  other 

territories, may not actually lead to a faster development. 

•

•

•

•

•

The  Company  has  no  manufacturing  capabilities  and  relies  on  third-party  manufacturers  for  its 
product candidates. 

The Company relies on third parties to supply key materials used in its research and development, 
to provide services to the Company and to assist with clinical studies. 

The  Company  depends  upon  its  existing  collaboration  partners,  AstraZeneca,  Sanofi  and  other 
third  parties,  and  may  depend  upon  future  collaboration  partners  to  commit  to  the  research, 
development, manufacturing and marketing of its drugs. 

The  late-stage  development  and  marketing  of  the  Company’s  product  candidates  may  partially 
depend on its ability to establish collaborations with major biopharmaceutical companies. 

The Company has incurred and may in the future incur significant operational losses related to its 
research and development activities. 

9

•

•

•

•

•

•

•

•

•

•

The  Company  may  need  to  raise  additional  funding  to  complete  the  development  and  any 
commercialization of its product candidates, which may not be available on acceptable terms, or 
at  all,  and  failure  to  obtain  this  necessary  capital  when  needed  may  force  it  to  delay,  limit  or 
terminate its product development efforts or other operations. 

If the Company does not achieve its product development or commercialization objectives in the 
timeframes  it  expects,  the  Company  may  not  receive  product  revenue  or  milestone  or  royalty 
payments, and it may not be able to conduct its operations as planned. 

The  revenues  generated  from  the  Company’s  collaboration  and  license  agreements  have 
contributed and are expected to contribute a large portion of its revenue for the foreseeable future. 

The Company benefits from tax credits in France that could be reduced or eliminated. 

The  current  state  of  the  world  financial  market  and  current  economic  conditions  could  have  a 
material adverse impact on the Company's business, financial condition and results of operations.

The Company's business could be affected by natural disaster, such as wildfire, and this could be 
exacerbated by climate change.

The Company’s ability to compete may be adversely affected if the Company does not adequately 
obtain, maintain, protect and enforce its intellectual property or proprietary rights, or if the scope 
of intellectual property protection the Company obtains is not sufficiently broad. 

The Company’s patents could be found invalid or unenforceable if challenged, and it may not be 
able to protect its intellectual property. 

The  dual  listing  of  the  Company’s  ordinary  shares  and  the  ADSs  may  adversely  affect  the 
liquidity and value of the ADSs. 

The  Company  may  be  affected  by  political,  social,  legal  and  economic  instability,  civil  unrest, 
war  and  other  geopolitical  tension,  such  as  the  ongoing  military  conflict  between  Russia  and 
Ukraine and economic sanctions related thereto.

D.  Risk Factors 

The Company's business faces significant risks. You should carefully consider all of the information set 
forth  in  this  Annual  Report  and  in  the  other  filings  with  the  SEC,  including  the  following  risk  factors 
which Innate faces and which are faced by its industry. The Company's business, financial condition or 
results  of  operations  could  be  materially  adversely  affected  by  any  of  these  risks.  This  report  also 
contains forward-looking statements that involve risks and uncertainties. Innate's results could materially 
differ from those anticipated in these forward-looking statements, as a result of certain factors, including 
the  risks  described  below  and  elsewhere  in  this  Annual  Report  and  its  other  SEC  filings.  See  “Special 
Note Regarding Forward-Looking Statements” above.

Risks Related to the Development of the Product Candidates 

Biopharmaceutical  development  involves  a  high  degree  of  uncertainty  and  most  of  the  product 
candidates are in early stages of development, which makes it difficult to evaluate the current business 
and future prospects and may increase the risk of your investment. 

Innate  Pharma  is  a  global,  clinical  stage  oncology-focused  biotech  company  developing  a  portfolio  of 
product  candidates,  some  of  which  Innate  is  co-developing,  in  the  early  stages  of  clinical  development 
and preclinical programs.

A  key  element  of  Innate's  strategy  is  to  mature  and  expand  its  portfolio  of  proprietary  and  partnered 
product candidates to address unmet medical needs in immuno-oncology. Although Innate's research and 
development efforts to date have resulted in a pipeline of product candidates, all of its product candidates 
require  additional  development,  regulatory  review  and  approvals,  substantial  investment,  access  to 
sufficient  commercial  manufacturing  capacity  and  significant  marketing  efforts  before  they  can  be 
commercialized  and  before  Innate  can  generate  any  revenue  from  product  sales  or  royalties.  If  the 
Company  or  its  collaboration  partners  are  unable  to  successfully  develop  and  market  these  product 
candidates,  its  business,  prospects,  financial  condition  and  results  of  operations  may  be  adversely 
affected. 

Aside from Innate's commercial experience with Lumoxiti that ended in December 2020, its operations to 
date  have  been  limited  to  developing  its  product  candidates  and  undertaking  preclinical  studies  and 
clinical  studies  of  its  product  candidates,  including  monalizumab  and  IPH5201,  through  its  partnership 
with  AstraZeneca; IPH6101/SAR'579 through its partnership with Sanofi; and lacutamab, IPH5301 and 
IPH6501,  its  most  advanced  product  candidates,  currently  in  the  clinical  stage.  The  success  in 
development of its current and future product candidates by the Company or its collaborators will depend 
on many factors, including:

•

•

•

•

•

obtaining  positive  results  in  clinical  trials,  including  by  demonstrating  efficacy,  safety  and 
durability of effect of such product candidates; 

completing preclinical studies and receiving regulatory approvals or clearance for conducting 
clinical trials for its preclinical programs; 

receiving  and  maintaining  approvals  for  commercialization  of  such  product  candidates  from 
regulatory authorities; 

manufacturing  or  overseeing  the  manufacturing  of  its  product  candidates  in  acceptable 
quantities and at an acceptable cost; 

negotiating  favorable  terms  in  any  collaboration,  licensing  or  other  arrangements  into  which 
the Company may enter, and performing its obligations pursuant to such arrangements; 

11

•

•

•

maintaining,  protecting,  enforcing  and  expanding  its  portfolio  of  intellectual  property  rights, 
including patents, trade secrets and know-how; 

avoiding  and  defending  against  third-party  interference,  infringement  or  other  intellectual 
property claims; and 

maintaining  and  growing  an  organization  of  scientists,  medical  professionals  and  marketing, 
distribution  and  sales  personnel  and  executives  who  can  develop  its  product  candidates  and 
commercialize any approved products. 

In  addition,  if  the  Company  is  unable  to  reduce  its  dependence  on  its  current  clinical  and  preclinical 
product  candidates,  either  by  in-licensing  or  acquiring  new  product  candidates,  developing  its  other 
product  candidates  or  discovering  new  product  candidates,  the  Company  may  be  similarly  adversely 
affected.

The scientific evidence to support the feasibility of developing product candidates is both preliminary 
and limited. 

Innate Pharma's innovative approach to immuno-oncology aims to activate both the innate and adaptive 
immune  systems  against  abnormal  or  cancerous  cells  and  restore  the  body’s  ability  to  disrupt  their 
proliferation, potentially leading to durable responses in patients. This approach is focused on developing 
checkpoint inhibitors, tumor-targeting antibodies and antibodies that affect the tumor microenvironment, 
and several of the product candidates rely on novel mechanisms of action and on innovative formats for 
which the Company has limited scientific evidence and preclinical and clinical data. 

The  Company  may  not  ultimately  be  able  to  provide  the  FDA,  European  Medicines  Agency  (EMA)  or 
other regulatory authorities with substantial clinical evidence to support a claim of efficacy and durability 
of response to enable the applicable regulators to approve its product candidates for any indication. This 
may occur because later clinical studies fail to reproduce favorable data obtained in earlier clinical trials, 
because the applicable regulator disagrees with how the Company interprets the data from these clinical 
trials  or  because  the  applicable  regulator  does  not  accept  these  therapeutic  effects  as  valid  endpoints  in 
pivotal  clinical  trials  that  are  sufficient  to  grant  marketing  approval.  Additionally,  because  product 
candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite 
having progressed through preclinical studies and earlier clinical studies, its collaborators in earlier stages 
of clinical trials may eventually choose to discontinue later stage studies. For example, following initial 
promising results assessing the safety and efficacy of the Company's product candidate lirilumab for the 
treatment of various cancer indications, the Company's collaborator decided not to continue development 
after receiving Phase 2 clinical study data. Moreover, in 2022, AstraZeneca informed Innate Pharma of 
the discontinuation of the Interlink-1 Phase 3 clinical study assessing monalizumab in combination with 
cetuximab in patients with recurrent or metastatic squamous cell carcinoma of the head and neck, as this 
combination did not meet a pre-defined threshold for efficacy.

In  addition  to  the  safety  and  efficacy  traits  of  any  product  candidate,  clinical  study  failures  may  result 
from  a  multitude  of  factors,  including  flaws  in  study  design,  dose  selection,  placebo  effect  and  patient 
enrollment  criteria.  A  number  of  companies  in  the  pharmaceutical  industry  have  suffered  significant 
setbacks  in  advanced  clinical  studies  due  to  lack  of  efficacy  or  adverse  safety  profiles,  notwithstanding 
promising results in earlier studies, and it is possible that the Company will as well. Based upon negative 
or  inconclusive  results,  the  Company  or  its  collaborators  may  decide,  or  regulators  may  require  the 
Company,  to  conduct  additional  clinical  studies  or  preclinical  studies.  In  addition,  data  obtained  from 
studies are susceptible to varying interpretations, and regulators may not interpret the Company's data as 
favorably as the Company does, which may delay, limit or prevent regulatory approval. 

12

The Company will also need to demonstrate that its product candidates are safe and well tolerated. The 
Company does not have significant data on possible harmful long-term effects of its product candidates 
and does not expect to have this data in the near future. As a result, its ability to generate clinical safety 
and efficacy data sufficient to support submission of a marketing application or commercialization of its 
product candidates is uncertain and is subject to significant risk.

The Company intends to develop several of its product candidates in combination with other therapies, 
which exposes the Company to additional risks. 

The Company is currently developing monalizumab, lacutamab, IPH5201 and IPH5301, and may develop 
other  product  candidates,  in  combination  with  one  or  more  currently  approved  cancer  therapies. 
Specifically,  AstraZeneca  is  currently  evaluating  monalizumab  in  ongoing  Phase  1,  2  and  3  trials  in 
combination with durvalumab, an anti-PD-L1 immune checkpoint inhibitor. Lacutamab is also currently 
evaluated in combination with chemotherapy GEMOX (gemcitabine in combination with oxaliplatin) in 
patients with PTCL (Peripheral T Cell Lymphoma). In addition, IPH5201 is also currently under clinical 
investigation, in a Phase 2 study in combination with durvalumab and chemotherapy. Finally, IPH5301 is 
currently under clinical investigation in a Phase 1 study in combination with a chemotherapy, paclitaxel 
and trastuzumab. Patients may not be able to tolerate the Company's product candidates in combination 
with  other  therapies,  and  preliminary  clinical  results  indicate  that  monalizumab,  for  example,  has  no 
meaningful clinical activity as a monotherapy. Even if any product candidate the Company develops were 
to receive marketing approval or be commercialized for use in combination with other existing therapies, 
the Company would continue to be subject to the risks that the FDA, EMA or other comparable foreign 
regulatory authorities could revoke approval of the therapy used in combination with its product candidate 
or  that  safety,  efficacy,  manufacturing  or  supply  issues  could  arise  with  these  existing  therapies. 
Combination  therapies  are  commonly  used  for  the  treatment  of  cancer,  and  the  Company  would  be 
subject to similar risks if the Company develops any of its product candidates for use in combination with 
other  therapies  or  for  indications  other  than  cancer.  This  could  result  in  its  own  products,  if  approved, 
being removed from the market or being less successful commercially. 

The Company may also evaluate any of its current and future product candidates in combination with one 
or  more  other  cancer  therapies  that  have  not  yet  been  approved  for  marketing  by  the  FDA,  EMA  or 
comparable  foreign  regulatory  authorities.  The  Company  will  not  be  able  to  market  and  sell 
monalizumab, lacutamab, IPH5201 or IPH5301 or any other product candidate the Company develops in 
combination with any such unapproved cancer therapies that do not ultimately obtain marketing approval. 

If  the  FDA,  EMA  or  other  comparable  foreign  regulatory  authorities  do  not  approve,  revoke  their 
approval  of,  or  if  safety,  efficacy,  manufacturing  or  supply  issues  arise  with,  the  products  or  product 
candidates  the  Company  chooses  to  evaluate  in  combination  with  monalizumab,  lacutamab,  IPH5201, 
IPH5301 or any other product candidate the Company develops, the Company may be unable to obtain 
approval of or market monalizumab or any other such product candidate the Company develops. 

The Company is heavily dependent on the success of its current clinical-stage product candidates, and 
it  cannot  be  certain  that  it  or  its  collaborators  will  be  able  to  obtain  regulatory  approval  for,  or 
successfully commercialize, these product candidates. 

The  Company's  business  and  future  success  depend  on  receiving  regulatory  approval  for,  and  the 
commercial  success  of,  its  proprietary  and  partnered  product  candidates.  The  Company  has  agreements 
with  AstraZeneca  with  respect  to  the  advanced  development,  clinical  study  collaboration  and  potential 
future  registration  and  marketing  of  several  of  its  product  candidates,  including  monalizumab  and 
IPH5201,  and  with  Sanofi  for  the  research  and  development  of  IPH6101/SAR'579,  IPH6401/SAR’514, 
IPH62 and of another program in solid tumors. Its near-term prospects depend heavily on AstraZeneca’s 
successful clinical development and commercialization of monalizumab, as well as the successful clinical 

13

development of its other product candidates. The clinical success of these product candidates will depend 
on a number of factors, including the ability and willingness of AstraZeneca, Sanofi and the Company's 
other  collaborators  to  complete  ongoing  clinical  studies  respectively  for  monalizumab  and  IPH6101/
SAR'579  or  other  partnered  assets,  the  ability  to  complete  the  clinical  trials  for  which  the  Company  is 
responsible and the safety, tolerability and efficacy of its product candidates. 

The Company may not be successful in its efforts to develop additional products that receive regulatory 
approval and are successfully commercialized. 

The development of a product candidate is a long, costly and uncertain process, aimed at demonstrating 
the  therapeutic  benefit  of  a  product  candidate  that  competes  with  existing  products  or  those  being 
developed.  There  is  no  guarantee  that  the  Company  or  its  collaborators  will  be  able  to  demonstrate  a 
sufficient  degree  of  clinical  efficacy  or  safety  of  one  or  more  of  its  proprietary  or  licensed  product 
candidates  in  order  to  gain  regulatory  approval  or  to  become  commercially  viable.  The  degree  of 
uncertainty  associated  with  clinical  development  and  the  risks  associated  with  developing  new  product 
candidates may make it difficult to evaluate its current business and its future prospects. 

The  Company  intends  to  continue  to  develop  its  product  candidates  that  are  currently  in  clinical  trials, 
including monalizumab, lacutamab, IPH5201, IPH5301, IPH6101/SAR'579 and IPH6501. Monalizumab 
is  currently  being  investigated  in  multiple  Phase  1,  Phase  2  and  Phase  3  clinical  studies  under  a  co-
development  agreement  with  AstraZeneca.  Lacutamab  is  currently  being  investigated  in  an  open-label, 
multi-cohort Phase 2 clinical study in CTCL and in Phases 1 and 2 in PTCL. IPH5201 is currently being 
investigated in an open-label Phase 2 clinical study. IPH5301 is currently being investigated in a Phase 1 
clinical study sponsored by the Institut Paoli-Calmettes. IPH6101/SAR'579 is currently investigated in a 
Phase 1/2 clinical study sponsored by Sanofi. IPH6501 is currently investigated in a first-in-human, Phase 
1/2 study in B-Cell non-Hodgkin lymphoma indication.

While  the  Company  believes  that  it  will  eventually  have  the  in-house  capabilities  to  complete  the 
development  and/or  support  the  development  by  a  partner  of  monalizumab,  lacutamab,  IPH5201, 
IPH5301,  IPH6101/SAR'579  and  IPH6501,  the  Company  has  not  yet  completed  the  clinical  studies  for 
these  or  other  product  candidates,  and  there  can  be  no  assurance  that  these  or  other  product  candidates 
will gain regulatory approval or become commercially viable. 

Delays  in  the  preclinical  development  of  a  product  candidate  could  lead  to  delays  in  initiating  clinical 
development. A failure in the preclinical development of a product candidate could lead to abandoning its 
development. Further delays or failures at the various clinical stages for a given indication could result in 
delay  or  halt  the  development  of  the  product  candidate  in  such  indication  or  in  other  indications. 
Moreover, disappointing results during the initial Phases of development are often not a sufficient basis 
for  deciding  whether  or  not  to  continue  a  project.  At  these  early  stages,  sample  sizes,  the  duration  of 
studies and the parameters examined may not be sufficient to enable a definitive conclusion to be drawn, 
in which case further investigations are required. Conversely, promising results during the initial phases, 
and even after advanced clinical studies have been conducted, do not guarantee that a product candidate 
or an approved drug will be successfully approved and commercialized. 

The  risks  related  to  the  failure  of  a  product  candidate’s  development  are  highly  related  to  the  stage  of 
maturity  of  the  product  candidate.  Given  the  relatively  early  stage  of  the  product  candidates  in  the 
pipeline,  there  is  a  substantial  risk  that  some  or  all  of  the  product  candidates  will  not  obtain  regulatory 
approval  or  be  commercialized,  which  would  have  an  adverse  impact  on  the  Company's  business, 
prospects, financial condition and results of operations. 

14

The  Company  may  not  be  successful  in  its  efforts  to  identify,  discover  or  develop  additional  product 
candidates, including those based on its innovative ANKET® technology. 

The Company is seeking to develop a broad and innovative pipeline of product candidates in addition to 
monalizumab,  lacutamab,  avdoralimab,  IPH5201,  IPH5301,  IPH6101/SAR'579  and  IPH6501.  The 
Company may not be successful in identifying additional product candidates for clinical development for 
a number of reasons. For example, its research methodology may be unsuccessful in identifying potential 
product  candidates  or  the  potential  product  candidates  the  Company  identifies  may  have  harmful  side 
effects,  lack  of  efficacy  or  other  characteristics  that  make  them  unmarketable  or  unlikely  to  receive 
regulatory approval. 
Moreover,  some  of  its  innovative  pipeline  of  product  candidates  are  based  on  its  innovative  ANKET® 
platform, which is not yet approved. The ANKET® platform consists of two different formats, tri-specific 
and tetra-specific antibodies. IPH6101/SAR'579 and IPH6401/SAR'514, in partnership with Sanofi, two 
tri-specific antibodies are currently being investigated in Phase I clinical studies. Another multi-specific is 
also  being  developed  in  partnership  with  Sanofi  (IPH62).  Moreover,  the  Company  is  developing 
IPH6501,  a  tetra-specific  proprietary  antibody,  which  obtained  the  FDA's  approval  to  start  a  first-in-
human study in July 2023. Even if the Company aims at maintaining a diversified pipeline, the use of an 
innovative technology represents additional risks in the product candidate development.

Research programs to pursue the development of the product candidates for additional indications and to 
identify  new  product  candidates  and  disease  targets  require  substantial  technical,  financial  and  human 
resources.  The  Company's  research  programs  may  initially  show  promise  in  identifying  potential 
indications  or  product  candidates,  yet  fail  to  yield  results  for  clinical  development  for  a  number  of 
reasons, including: 

•

•

•

the  research  methodology  used  may  not  be  successful  in  identifying  potential  indications  or 
product candidates; 
potential  product  candidates  and/or  its  ANKET®  technology  may,  after  further  study,  be 
shown to have harmful adverse effects or other characteristics that indicate they are unlikely to 
be effective drugs; or

it  may  take  greater  human  and  financial  resources  to  identify  additional  therapeutic 
opportunities  for  its  product  candidates  or  to  develop  suitable  potential  product  candidates 
through internal research programs than the Company will possess, thereby limiting its ability 
to diversify and expand its product portfolio. 

Accordingly,  there  can  be  no  assurance  that  the  Company  will  ever  be  able  to  identify  additional 
indications for its product candidates or to identify and develop new product candidates through internal 
research programs. The Company may focus its efforts and resources on potential product candidates or 
other potential programs that ultimately prove to be unsuccessful. 

The Company may encounter substantial delays in its clinical studies or may be unable to conduct its 
clinical studies on the timelines the Company expects. 

Clinical testing is expensive, time consuming and subject to uncertainty. The Company cannot guarantee 
that any clinical trials will be conducted as planned or completed on schedule, if at all. A failure of one or 
more  clinical  studies  can  occur  at  any  stage  of  testing,  and  its  future  clinical  studies  may  not  be 
successful. Events that may prevent successful or timely completion of clinical development include: 

•

•

inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support 
the initiation of clinical trials; 

delays or failure in reaching a consensus with regulatory agencies on clinical study design; 

15

•

delays  in  reaching  agreement  on  acceptable  terms  with  prospective  Contract  Research 
Organisations (CROs) and investigational sites, the terms of which can be subject to extensive 
negotiation and may vary significantly among different CROs and investigational sites; 

imposition  of  a  temporary  or  permanent  clinical  hold  by  regulatory  agencies,  including  as  a 
result of a new safety finding that presents unreasonable risk to clinical study participants, a 
negative  finding  from  an  inspection  of  its  clinical  trial  operations  or  investigational  sites, 
developments in trials conducted by competitors for related technology that raise regulators’ 
concerns about risk to patients of the technology broadly or if a regulatory body finds that the 
investigational protocol or plan is clearly deficient to meet its stated objectives. For example, 
in November 2019 and in October 2023, the TELLOMAK study sponsored by the Company 
was put on full or partial holds in a number of countries. The Company was authorized to fully 
resume patient enrollment and treatment after being able to provide the agencies with expected 
material and information ;

delays in recruiting suitable patients to participate in its clinical studies; 

difficulty collaborating with patient groups and investigators; 

failure by the Company, its CROs or other third parties, including its collaborators, to adhere 
to clinical study requirements; 

delays in having patients complete participation in a clinical study or return for post-treatment 
follow-up; 

patients withdrawing from a clinical study; 

occurrence of adverse events associated with a product candidate that are viewed to outweigh 
its potential benefits; 

changes  in  regulatory  requirements  and  guidance  that  require  amending  or  submitting  new 
clinical trial protocols; 

regulatory feedback requiring the Company to amend the protocols of ongoing clinical studies 
in response to safety considerations, as the Company has previously been required to; 

changes in the standard of care on which a clinical development plan was based, which may 
require new or additional clinical trials; 

the  cost  of  clinical  studies  of  its  product  candidates  being  greater  than  the  Company 
anticipates; 

clinical  studies  of  its  product  candidates  producing  negative  or  inconclusive  results,  which 
may  result  in  the  Company  deciding,  or  regulators  requiring  the  Company,  to  conduct 
additional clinical studies or abandon product development programs;

transfer  of  manufacturing  processes  to  larger-scale  facilities  operated  by  either  a  contract 
manufacturing  organization  (CMO)  and  delays  or  failure  by  its  CMOs  or  the  Company  to 
make any necessary changes to such manufacturing process; and 

batch recalls, recalls of manufactured product candidates or delays in manufacturing, testing, 
releasing,  validating,  or  importing  or  exporting  sufficient  stable  quantities  of  its  product 
candidates for use in clinical studies or the inability to do any of the foregoing.

Any  inability  to  successfully  complete  preclinical  and  clinical  development  could  result  in  additional 
costs  to  the  Company  or  impair  its  ability  to  generate  revenue.  In  addition,  if  the  Company  makes 
manufacturing or formulation changes to its product candidates, it may be required to or it may elect to 

16

conduct  additional  studies  to  bridge  its  modified  product  candidates  to  earlier  versions.  Clinical  study 
delays could also shorten any periods during which its products have patent protection and may allow its 
competitors  to  bring  products  to  market  before  the  Company  does,  which  could  impair  its  ability  to 
successfully commercialize its product candidates and may harm its business and results of operations. 

The Company depends on enrollment of patients in its clinical studies for its product candidates. 

Successful and timely completion of clinical studies will require that the Company or its subcontractors 
enroll  a  sufficient  number  of  suitable  patients.  Clinical  studies  may  be  subject  to  delays  as  a  result  of 
patient  enrollment  taking  longer  than  anticipated  or  patient  withdrawal.  Patient  enrollment  depends  on 
many factors, including the size and nature of the patient population, which is typically limited for rare or 
orphan diseases, making the enrollment more difficult, eligibility criteria for the study, the proximity of 
patients to clinical sites, the design of the clinical protocol, the availability of competing clinical studies, 
the availability of new drugs approved for the indication the clinical study is investigating and clinicians’ 
and  patients’  perceptions  as  to  the  potential  advantages  of  the  drug  being  studied  in  relation  to  other 
available therapies. For example, the Company is developing lacutamab for the treatment of cutaneous T 
cell lymphoma (CTCL). CTCL is an orphan disease, which means that the potential patient population is 
limited.  In  addition,  there  are  several  other  product  candidates  potentially  in  development  for  the 
indications for which the Company is developing product candidates, and the Company may compete for 
patients with the sponsors of trials for those drugs. These factors may make it difficult for the Company to 
enroll enough patients to complete its clinical studies in a timely and cost-effective manner. Delays in the 
completion  of  any  clinical  study  of  any  of  its  product  candidates  will  increase  its  costs,  slow  down  its 
product  candidate  development  and  approval  process  and  delay  or  potentially  jeopardize  its  ability  to 
commence product sales and generate revenue. In addition, some of the factors that cause, or lead to, a 
delay in the commencement or completion of clinical studies may also ultimately lead to the inability to 
obtain regulatory approval of its product candidates.

The  Company's  product  candidates  in  development  may  cause  undesirable  side  effects  or  have  other 
properties that could halt or delay their clinical development, prevent their regulatory approval, limit 
their commercialization or result in other negative consequences. 

Use of the Company's product candidates in development could be associated with side effects or adverse 
events,  which can vary in severity and in frequency. Undesirable side effects or unacceptable toxicities 
caused  by  its  products  or  product  candidates  could  cause  the  Company  or  regulatory  authorities  to 
interrupt, delay or halt clinical studies. The FDA or European regulatory authorities could delay or deny 
approval of the Company's product candidates for any or all targeted indications and negative side effects 
could result in a more restrictive label for any drug that is approved. Side effects such as toxicity or other 
safety  issues  associated  with  the  use  of  the  Company's  product  candidates  could  also  require  it  or  its 
collaborators to perform additional studies or halt development of product candidates or sale of approved 
products. 

Treatment-related  side  effects  could  also  affect  patient  recruitment  or  the  ability  of  enrolled  subjects  to 
complete the trial, or could result in potential product liability claims. In addition, these side effects may 
not be appropriately or timely recognized or managed by the treating medical staff, as toxicities resulting 
from  immunotherapy  are  not  normally  encountered  in  the  general  patient  population  and  by  medical 
personnel.  Inadequate  training  in  recognizing  or  managing  the  potential  side  effects  of  its  product 
candidates could result in adverse effects to patients, including death. Any of these occurrences may have 
an adverse impact on the Company's business, prospects, financial condition and results of operations. 

17

The Company faces substantial competition from companies with significantly greater resources and 
experience. 

The biotechnology and pharmaceutical market, and notably the immuno-oncology field, is characterized 
by  rapidly  advancing  technologies,  products  protected  by  intellectual  property  rights  and  intense 
competition and is subject to significant and rapid change as researchers learn more about diseases and 
develop new technologies and treatments. The Company faces potential competition from many different 
sources,  including  major  pharmaceutical  companies,  specialty  pharmaceutical  and  biotechnology 
companies, academic institutions and governmental agencies and public and private research institutions. 
Any  product  candidates  that  the  Company  or  its  collaborators  successfully  develop  will  compete  with 
existing therapies and new therapies that may become available in the future. If competing products are 
marketed before Innate's ones, or at lower prices, or cover a wider therapeutic spectrum, or if they prove 
to be more effective or better tolerated, the Company's business, prospects, financial condition and results 
of operations could be affected. 

Many  of  the  Company's  competitors  who  are  developing  immuno-oncology  and  anti-cancer  therapies 
have  considerably  greater  resources  and  experience 
in  research,  drug  development,  finance, 
manufacturing,  marketing,  technology  and  personnel  and  access  to  patients  for  clinical  studies  than  the 
Company does. In particular, large pharmaceutical companies have substantially more experience than the 
Company  does  in  conducting  clinical  studies  and  obtaining  regulatory  authorizations.  Mergers  and 
acquisitions  in  the  pharmaceutical,  biotechnology  and  diagnostic  industries  may  result  in  even  more 
resources being concentrated among a smaller number of the Company's competitors. Smaller or early-
stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative 
arrangements with large and established companies. These competitors are also likely to compete with the 
Company to recruit and retain scientific and management personnel, acquire rights for promising product 
candidates  and  other  complementary  technologies,  establish  clinical  investigational  sites  and  patient 
registration for clinical studies and acquire technologies complementary to, or necessary for, its programs, 
as  well  as  to  enter  into  collaborations  with  partners  who  have  access  to  innovative  technologies.  If  the 
Company cannot successfully compete with new or existing products, its marketing and sales will suffer 
and  the  Company  may  never  be  profitable.  Should  any  of  these  risks  materialize,  Innate's  business, 
prospects, financial condition and results of operations may be adversely affected. 

The Company cannot guarantee that its product candidates will: 

•

•

•

•

obtain  regulatory  authorizations  or  become  commercially  available  before  those  of  its 
competitors; 

remain  competitive  in  the  face  of  other  products  developerid  by  its  competitors,  which  may 
prove to be safer, more effective, have fewer or less severe side effects, be more convenient, 
have a broader label, have more robust intellectual property protection or be less expensive; 

remain  competitive  in  the  face  of  products  of  competitors  that  are  more  efficient  in  their 
manufacturing or more effective in their marketing; and 

not become obsolete or unprofitable due to technological progress or other therapies developed 
by its competitors. 

In addition, while any future product candidate that is approved may compete with many existing drugs or 
other therapies, to the extent it is solely used in combination with these therapies, the Company's product 
candidates will not be competitive with such therapies, but any sales of such products could be limited to 
sales of the combination therapy. In this case, the Company would be exposed to the same competitive 
risks as the product used in combination with its product, such as a product that is marketed before the 
combination therapy, has lower prices, covers a wider therapeutic spectrum or proves to be more effective 

18

or  better  tolerated.  For  additional  information  regarding  competition  to  its  business  see  “Business—
Competition.”

Risks  Related  to  Regulatory  Approval  and  Marketing  of  Innate's  Product  Candidates  and  Legal 
Compliance Matters

Even if the Company completes the necessary preclinical and clinical studies, the marketing approval 
process  is  expensive,  time-consuming  and  uncertain  and  may  prevent  the  Company  from  obtaining 
approvals for the commercialization of some or all of its product candidates. If the Company is not able 
to obtain, or if there are delays in obtaining, required regulatory approvals, in particular in the United 
States or the European Union, the Company will not be able to commercialize its product candidates, 
and its ability to generate revenue will be materially impaired. 

The  research  and  development  of  pharmaceutical  products  is  governed  by  complex  regulatory 
requirements.  The  regulatory  agencies  that  oversee  these  requirements  have  the  authority  to  permit  the 
commencement  of  clinical  studies  or  to  temporarily  or  permanently  halt  a  study.  They  are  entitled  to 
request  additional  clinical  data  before  authorizing  the  commencement  or  resumption  of  a  study,  which 
could result in delays or changes to the product development plan. As the Company advances its product 
candidates, the Company will be required to consult with these regulatory agencies and comply with all 
applicable guidelines, rules and regulations. If the Company fails to do so, the Company may be required 
to delay or discontinue development of its product candidates. Delay or failure to obtain, or unexpected 
costs in obtaining, the regulatory approval necessary to bring a potential product to market could decrease 
its ability to generate sufficient product revenue to maintain its business. 

The  clinical  studies  of  Innate's  product  candidates,  the  manufacturing  and  the  marketing  of  its  product 
candidates are and will be, subject to regulation by numerous government authorities in the United States, 
in the European Union and in other countries where the Company intends to test and, if approved, market 
any  product  candidate.  Before  obtaining  regulatory  approvals  for  the  commercial  sale  of  any  product 
candidate, the Company must demonstrate, with substantial evidence gathered in well-controlled clinical 
trials, and, with respect to approval in the United States, to the satisfaction of the FDA, with respect to 
approval  in  the  European  Union,  to  the  satisfaction  of  the  EMA  or,  with  respect  to  approval  in  other 
countries, similar regulatory authorities in those countries, that the product candidate is safe and effective 
for use in each target indication. 

When the Company acquired Lumoxiti, AstraZeneca had already obtained marketing approval from the 
FDA  and  they  also  filed  the  Marketing  Authorization  in  the  European  Union.  The  Company  has  never 
submitted  a  product  candidate  for  marketing  approval  in  the  United  States,  in  the  European  Union  or 
elsewhere. 

In  the  United  States,  the  Company  expects  that  the  requisite  regulatory  submission  to  seek  marketing 
authorization for its product candidates will be a Biologic License Application (BLA) and the competent 
regulatory  authority  is  the  FDA.  In  the  European  Union,  the  requisite  approval  is  a  Marketing 
Authorization (MA), which for products developed by the means of antibody-based therapeutics, gene or 
cell  therapy  products  as  well  as  tissue  engineered  products,  is  issued  through  a  centralized  procedure 
involving the EMA (see “Business—Regulation”). Satisfaction of these and other regulatory requirements 
is  costly,  time  consuming,  uncertain  and  subject  to  unanticipated  delays.  Failure  to  comply  with  the 
applicable  requirements  at  any  time  during  the  product  development  process,  approval  process  or  after 
approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include, 
for  example,  the  FDA’s  refusal  to  approve  pending  applications,  withdrawal  of  an  approval,  a  clinical 
hold, untitled or warning letters, product recalls or withdrawals from the market, product seizures, total or 

19

partial  suspension  of  production  or  distribution  injunctions,  fines,  refusals  of  government  contracts, 
restitution, disgorgement or civil or criminal penalties. 

Data from preclinical and clinical studies are likely to give rise to different interpretations, which could 
delay regulatory authorization, restrict the scope of any such authorization or force Innate to repeat trials 
in order to meet the requirements of the various regulators. Regulatory requirements and processes vary 
widely  among  countries,  and  the  Company  may  be  unable  to  obtain  authorization  within  each  relevant 
country  in  a  timely  manner.  Regulatory  authorities  may  prevent  Innate  from  starting  clinical  studies  or 
continuing  clinical  development  if  the  data  were  not  produced  according  to  applicable  regulations  or  if 
they consider that the balance between the expected benefits of the product and its possible risks is not 
sufficient to justify the trial. 

Despite the Company's efforts, its product candidates may not: 

•

•

•

offer improvement over existing, comparable products; 

be proven safe and effective in clinical trials; or 

meet applicable regulatory standards. 

This  process  can  take  many  years  and  may  include  post-marketing  studies  and  surveillance,  which  will 
require the expenditure of substantial resources beyond the existing cash on hand. Of the large number of 
drugs  in  development  globally,  only  a  small  percentage  successfully  complete  the  regulatory  approval 
process  and  not  all  approved  drugs  are  successfully  commercialized.  Delay  or  failure  to  obtain,  or 
unexpected costs in obtaining, the regulatory approval necessary for the Company or its partners to bring 
a  potential  product  candidate  to  market  could  have  a  material  adverse  effect  on  its  business,  prospects, 
financial condition and results of operations. 

The regulatory processes that will govern the approval of Innate's product candidates are complex and 
changes  in  regulatory  requirements  could  result  in  delays  or  discontinuation  of  development  or 
unexpected costs in obtaining regulatory approval. 

The Company's product candidates are based on new approaches and/or technologies that are constantly 
evolving and have not been extensively tested on humans. The applicable regulatory requirements vary 
between  jurisdictions  and  are  also  complex,  potentially  difficult  to  apply  and  subject  to  significant 
modifications.  Modifications  to  regulations  during  the  course  of  clinical  development  and  regulatory 
review may lead to delays or the refusal of authorization. 

In Europe, the United States and other countries, regulations can potentially: 

•

•

•

significantly delay or increase the cost of development, testing, manufacturing and marketing 
of Innate's products;

limit the indications for which the Company will be authorized to market its products; and 

impose  new,  more  stringent  requirements,  suspend  marketing  authorizations  or  request  the 
suspension of clinical trials or the marketing of its products if unexpected results are obtained 
during trials performed by other researchers on products similar to its products. 

Marketing  authorization  in  one  jurisdiction  does  not  ensure  marketing  authorization  in  another,  but  a 
failure or delay in obtaining marketing authorization in one jurisdiction may have a negative effect on the 
regulatory process in others. Failure to obtain marketing authorization in other countries or any delay or 
setback in obtaining such approval would impair the Company's ability to develop additional markets for 
its product candidates. This would reduce Innate's target market and limit the full commercial potential of 
its product or product candidates. Should any of these risks materialize, this could harm its business. 

20

Innate Pharma's failure to obtain marketing approval in jurisdictions other than the United States and 
Europe  would  prevent  Innate's  product  candidates  from  being  marketed  in  these  other  jurisdictions, 
and any approval the Company is granted for its product candidates in the United States and Europe 
would not assure approval of product candidates in other jurisdictions. 

In order to market and sell its other product candidates in jurisdictions other than the United States and 
Europe, the Company must obtain separate marketing approvals and comply with numerous and varying 
regulatory requirements. The approval process varies among countries and can involve additional testing. 
The time required to obtain approval may differ from that required to obtain FDA approval or approvals 
from  regulatory  authorities  in  the  European  Union.  The  regulatory  approval  process  outside  the  United 
States and Europe generally includes all of the risks associated with obtaining FDA approval or approvals 
from regulatory authorities in the European Union. In addition, some countries outside the United States 
and Europe require approval of the sales price of a product before it can be marketed. In many countries, 
separate procedures must be followed to obtain reimbursement, and a product may not be approved for 
sale in the country until it is also approved for reimbursement. The Company may not obtain marketing, 
pricing  or  reimbursement  approvals  outside  the  United  States  and  Europe  on  a  timely  basis,  if  at  all. 
Approval  by  the  FDA  or  regulatory  authorities  in  the  European  Union  does  not  ensure  approval  by 
regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside 
the  United  States  and  Europe  does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or 
jurisdictions or by the FDA or regulatory authorities in the European Union. The Company may not be 
able  to  file  for  marketing  approvals  and  may  not  receive  necessary  approvals  to  commercialize  its 
products  in  any  market.  Marketing  approvals  in  countries  outside  the  United  States  and  Europe  do  not 
ensure pricing approvals in those countries or in any other countries, and marketing approvals and pricing 
approvals do not ensure that reimbursement will be obtained. 

Side effects that appear following the launch of a drug on the market may result in the product being 
taken  off  the  market  or  additional  warnings  being  added  to  the  label  despite  having  obtained  all 
regulatory approvals. 

A drug’s launch in the market may expose a large number of patients to potential risks associated with 
treatment  with  a  new  pharmaceutical  product.  Certain  side  effects,  which  may  not  have  been  identified 
during clinical trials, can subsequently appear. For these reasons, regulatory agencies require companies 
to implement post-approval monitoring. Depending on the occurrence of serious undesirable effects, the 
agencies may require that the Company or a collaboration partner take a drug off the market temporarily 
or permanently, even if it is effective and has obtained all the necessary marketing authorizations. Such an 
action would negatively impair the Company's ability to generate revenue from such product and could 
more generally negatively affect its ability to develop, obtain regulatory approval for, and commercialize 
its  other  product  candidates  and  its  reputation  generally,  each  of  which  could  have  a  material  adverse 
effect  on  its  business  and  results  of  operations.  In  addition,  if  the  product  candidates  the  Company 
develops  receive  marketing  authorization  and  the  Company  or  others  identify  undesirable  side  effects 
caused by any product after the approval, a number of potentially significant negative consequences could 
result,  including  that  regulatory  authorities  may  require  the  addition  of  labeling  statements,  such  as  a 
“boxed”  warning  or  a  contraindication,  the  Company  may  be  required  to  create  a  medication  guide 
outlining the risks of such side effects for distribution to patients and its reputation may suffer. 

Any  product  candidate  for  which  the  Company  obtains  marketing  approval  will  be  subject  to  strict 
enforcement  of  post-marketing  requirements  and  the  Company  could  be  subject  to  substantial 
penalties, including withdrawal of its product from the market, if the Company fails to comply with all 

21

regulatory  requirements  or  if  the  Company  experiences  unanticipated  problems  with  its  product  and 
product candidates, when and if any of them are approved. 

Any  product  candidate  for  which  the  Company  obtains  marketing  approval  will  be  subject  to  continual 
requirements  of  and  review  by  the  FDA,  EMA  and  other  regulatory  authorities,  including  requirements 
relating  to  manufacturing  processes,  post-approval  clinical  data,  labeling,  advertising  and  promotional 
activities  for  such  product.  These  requirements  include,  but  are  not  limited  to,  restrictions  governing 
promotion  of  an  approved  product,  submissions  of  safety  and  other  post-marketing  information  and 
reports, registration and listing requirements, current good manufacturing practice (cGMP), requirements 
relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of  records 
and documents and requirements regarding the distribution of samples to physicians and recordkeeping. 
In addition, even if marketing approval of a product candidate is granted, the approval may be subject to 
limitations  on  the  indicated  uses  for  which  the  product  may  be  marketed,  restrictions  for  specified  age 
groups, warnings, precautions or contraindications or to the conditions of approval. 

The FDA and other federal and state agencies, including the U.S. Department of Justice (DOJ), closely 
regulate  compliance  with  all  requirements  governing  prescription  products,  including  requirements 
pertaining  to  marketing  and  promotion  of  products  in  accordance  with  the  provisions  of  the  approved 
labeling  and  manufacturing  of  products  in  accordance  with  cGMP  requirements.  The  FDA  and  DOJ 
impose  stringent  restrictions  on  manufacturers’  communications  regarding  off-label  use,  and  if  the 
Company  does  not  market  its  products  for  their  approved  indications,  the  Company  may  be  subject  to 
enforcement action for off-label marketing. Prescription products may be promoted only for the approved 
indications and in accordance with the provisions of the approved label. However, companies may also 
share truthful and not misleading information that is otherwise consistent with the labeling. Violations of 
such requirements may lead to investigations alleging violations of the Food, Drug and Cosmetic Act and 
other statutes, including the False Claims Act and other federal and state health care fraud and abuse laws, 
as  well  as  state  consumer  protection  laws.  The  Company's  failure  to  comply  with  all  regulatory 
requirements,  and  later  discovery  of  previously  unknown  adverse  events  or  other  problems  with  its 
products, manufacturers or manufacturing processes, may yield various results, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

litigation involving patients taking its products; 

restrictions on such products, manufacturers or manufacturing processes; 

restrictions on the labeling or marketing of a product; 

restrictions on product distribution or use; 

requirements to conduct post-marketing studies or clinical trials; 

warning letters or untitled letters; 

withdrawal of the products from the market; 

refusal  to  approve  pending  applications  or  supplements  to  approved  applications  that  the 
Company submits; 

recall of products; 

fines, restitution or disgorgement of profits or revenues; 

suspension or withdrawal of marketing approvals; 

damage to relationships with any potential collaborators;

unfavorable press coverage and damage to its reputation; 

refusal to permit the import or export of its products; 

22

•

•

product seizure; or 

injunctions or the imposition of civil or criminal penalties. 

Non-compliance  by  the  Company  or  any  future  collaborator  with  the  FDA,  EMA  or  other  regulatory 
requirements  regarding  safety  monitoring  or  pharmacovigilance,  and  with  requirements  related  to  the 
development  of  products  for  the  pediatric  population,  can  also  result  in  significant  financial  penalties. 
Similarly, failure to comply with regulatory requirements regarding the protection of personal information 
can also lead to significant penalties and sanctions. 

Coverage  and  reimbursement  may  be  limited  or  unavailable  in  certain  market  segments  for  the 
Company's product candidates, if approved, which could make it difficult for the Company to sell its 
product candidates profitably. 

Successful sales of its product candidates, if approved, will depend, in part, on the availability of adequate 
coverage and reimbursement from government authorities and third-party payors, such as private health 
insurers  and  health  maintenance  organizations.  Patients  who  are  provided  medical  treatment  for  their 
conditions generally rely on third-party payors to reimburse all or part of the costs associated with their 
treatment.  Adequate  coverage  and  reimbursement  from  governmental  healthcare  programs,  such  as 
Medicare  and  Medicaid  in  the  United  States  or  Social  Security  in  France,  and  commercial  payors  are 
critical to new product acceptance. 

Government  authorities  and  third-party  payors,  such  as  private  health  insurers  and  health  maintenance 
organizations,  decide  which  drugs  and  treatments  they  will  cover  and  the  amount  of  reimbursement. 
Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the 
third-party payor’s determination that use of a product is: 

•

•

•

•

•

a covered benefit under its health plan; 

safe, effective and medically necessary; 

appropriate for the specific patient; 

cost-effective; and 

neither experimental nor investigational. 

Policies for coverage and reimbursement for products vary among third-party payors. No uniform policy 
of coverage and reimbursement for products exists among third-party payors, and third-party payors are 
increasingly challenging the price, examining the medical necessity and reviewing the cost-effectiveness 
of approved drugs and medical services, in addition to questioning their safety and efficacy. As a result, 
obtaining  coverage  and  reimbursement  approval  of  a  product  from  a  government  or  other  third-party 
payor is a time-consuming and costly process that could require the Company or its partners to provide to 
each payor supporting scientific, clinical and cost-effectiveness data for the use of its products on a payor-
by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Coverage 
decisions may depend upon clinical and economic standards that disfavor new drug products when more 
established or lower cost therapeutic alternatives are already available or subsequently become available. 
Even  if  the  Company  obtains  coverage  for  a  given  product,  the  resulting  reimbursement  payment  rates 
might not be adequate for it to achieve or sustain profitability or may require co-payments that patients 
find  unacceptably  high.  Additionally,  third-party  payors  may  not  cover,  or  provide  adequate 
reimbursement for, long-term follow-up evaluations required following the use of the Company's product 
candidates or approved products. 

Because its product candidates represent new approaches to the treatment of cancer and, accordingly, may 
have a higher cost than conventional therapies and may require long-term follow-up evaluations, the risk 

23

that coverage and reimbursement rates may be inadequate for the Company to achieve profitability may 
be elevated. There are currently a limited number of immunotherapy products that are designed to treat 
cancer on the market and, accordingly, there is less experience or precedent for the reimbursement of such 
treatments by governmental entities or third-party payors. 

Government  restrictions  on  pricing  and  reimbursement  and  other  healthcare  cost-containment 
initiatives may negatively affect its ability to generate revenues for its product candidates for which the 
Company obtains regulatory approval. 

Government authorities and other third-party payors are developing increasingly sophisticated methods of 
controlling  healthcare  costs,  including  by  limiting  coverage  and  the  amount  of  reimbursement  for 
particular  medications.  Increasingly, 
that  pharmaceutical  and 
biotechnology  companies  provide  them  with  predetermined  discounts  from  list  prices  as  a  condition  of 
coverage,  are  using  restrictive  formularies  and  preferred  drug  lists  to  leverage  greater  discounts  in 
competitive classes and are challenging the prices charged for medical products. 

third-party  payors  are  requiring 

In  the  United  States,  the  European  Union  and  other  foreign  jurisdictions,  there  have  been  a  number  of 
legislative and regulatory changes to the healthcare system that could affect the Company's or its partners’ 
ability to sell its products profitably. 

On March 23, 2010, President Obama signed into law the Affordable Care Act (ACA), which includes a 
number  of  healthcare  reform  provisions  and  requires  most  U.S.  citizens  to  have  health  insurance.  The 
ACA,  among  other  things,  imposed  a  significant  annual  fee  on  companies  that  manufacture  or  import 
branded  prescription  drug  products;  addressed  a  new  methodology  by  which  rebates  owed  by 
manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, 
instilled, implanted or injected; increased the minimum Medicaid rebates owed by manufacturers under 
the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid 
managed care organizations; and establishes a new Medicare Part D coverage gap discount program, in 
which manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices of applicable 
brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the 
manufacturer’s  outpatient  drugs  to  be  covered  under  Medicare  Part  D.  Substantial  new  provisions 
affecting  compliance  also  have  been  added,  which  may  require  modification  of  business  practices  with 
healthcare  practitioners.  The  ACA  also  revised  the  definition  of  “average  manufacturer  price”  for 
reporting purposes, which could increase the amount of Medicaid drug rebates to states. 

There  have  been  judicial  congressional,  and  executive  branch  efforts  to  repeal,  modify  or  delay  the 
implementation  of  the  law.  In  July  and  December  2018,  CMS  published  final  rules  with  respect  to 
permitting  further  collections  and  payments  to  and  from  certain  ACA  qualified  health  plans  and  health 
insurance  issuers  under  its  risk  adjustment  program  in  response  to  the  outcome  of  federal  district  court 
litigation regarding the method CMS uses to determine this risk adjustment. Concurrently, Congress has 
considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has 
not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under 
the  ACA  have  been  signed  into  law.  The  Tax  Cuts  and  Jobs  Act  of  2017  includes  a  provision  that 
repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on 
certain  individuals  who  fail  to  maintain  qualifying  health  coverage  for  all  or  part  of  a  year,  commonly 
referred to as the “individual mandate.” On December 14, 2018, a Texas U.S. District Court Judge ruled 
that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by the U.S. 
Congress  as  part  of  the  Tax  Cuts  and  Jobs  Act  of  2017  Act.  Additionally,  on  June  17,  2021,  the  U.S. 
Supreme  Court  dismissed  a  challenge  on  procedural  grounds  that  the  ACA  is  unconstitutional  in  its 
entirety because the "individual mandate" was repealed by Congress. Thus, the ACA remains in effect in 
its current form. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden 
issued an executive order to initiate a special enrollment period which began on February 15, 2021, and 

24

remained open through August 15, 2021, for purposes of obtaining health insurance coverage through the 
ACA  marketplace.  The  executive  order  also  instructs  certain  governmental  agencies  to  review  and 
reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare,  including,  among  others, 
reexamining Medicaid demonstration projects and waiver programs that include work requirements, and 
policies  that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance  coverage  through 
Medicaid or the ACA. It is unclear how judicial and Congressional challenges and the healthcare reform 
measures of the Biden administration will impact the ACA. 

In addition, other legislative changes have been proposed and adopted in the United States since the ACA 
was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per 
fiscal year, which will remain in effect through 2030, unless additional Congressional action is taken by 
Congress, although they have been suspended by the Coronavirus Aid, Relief and Economic Security, or 
CARES, Act, until March 31, 2022. From April through June 2022, a 1% reduction was in effect. As of 
July  2,  2022,  the  2%  cut  resumed.  Both  the  Budget  Control  Act  of  2011  and  the  American  Taxpayer 
Relief  Act  of  2012  (ATRA)  further  reduced  Medicare  payments  to  several  providers  and  the  ATRA 
increased the statute of limitations period for the government to recover overpayments to providers from 
three  to  five  years.  Additional  legislative  proposals  to  reform  healthcare  and  government  insurance 
programs,  along  with  the  trend  toward  managed  healthcare  in  the  United  States,  could  influence  the 
purchase of medicines and reduce demand and prices for Innate's product candidates, if approved. This 
could harm Innate's or its partners’ ability to market any drugs and generate revenues. Cost containment 
measures that healthcare payors and providers are instituting and the effect of further healthcare reform 
could significantly reduce potential revenues from the sale of any of its product candidates approved in 
the future, and could cause an increase in its compliance, manufacturing, or other operating expenses. 

In addition, in the United States, federal programs impose penalties on drug manufacturers in the form of 
mandatory additional rebates and/or discounts if commercial prices increase at a rate greater than the U.S. 
Bureau of Labor Statistics consumer price index, and these rebates or discounts, which can be substantial, 
may affect the Company's ability to raise commercial prices. 

Further, there has been increasing legislative and enforcement interest in the United States with respect to 
drug  pricing  practices.  There  have  been  several  recent  U.S.  Congressional  inquiries  and  proposed  and 
enacted  federal  and  state  legislation  designed  to,  among  other  things,  bring  more  transparency  to  drug 
pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  reduce  the  cost  of 
drugs under Medicare and reform government program reimbursement methodologies for drugs. 

For example, in August 2022, the Inflation Reduction Act of 2022 was signed into law. This legislation 
contains substantial drug pricing reforms, including the establishment of a drug price negotiation program 
within the U.S. Department of Health and Human Services that would require manufacturers to charge a 
negotiated “maximum fair price” for certain selected drugs or pay an excise tax for noncompliance, the 
establishment of rebate payment requirements on manufacturers of certain drugs payable under Medicare 
Parts  B  and  D  to  penalize  price  increases  that  outpace  inflation,  and  requires  manufacturers  to  provide 
discounts on Part D drugs. The Inflation Reduction Act of 2022 also caps Medicare beneficiaries’ annual 
out-of-pocket drug expenses. Substantial penalties can be assessed for noncompliance with the IRA drug 
pricing provisions. Provisions of the IRA are subject to legal challenges, and the full impact of the IRA on 
the pharmaceutical industry remains uncertain.

The U.S. Congress and the current administration have each indicated that it will continue to seek new 
legislative and/or administrative measures to control drug costs.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed 
to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement 
constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and 

25

transparency measures, and, in some cases, designed to encourage importation from other countries and 
bulk purchasing.

In some countries, the proposed pricing for a biopharmaceutical product must be approved before it may 
be lawfully marketed. In addition, in certain foreign markets, the pricing of biopharmaceutical products is 
subject  to  government  control  and  reimbursement  may  in  some  cases  be  unavailable.  The  requirements 
governing drug pricing vary widely from country to country. For example, the European Union provides 
options  for  its  member  states  to  restrict  the  range  of  medicinal  products  for  which  their  national  health 
insurance systems provide reimbursement and to control the prices of medicinal products for human use. 
An EU member state may approve a specific price for the medicinal product, it may refuse to reimburse a 
product at the price set by the manufacturer or it may instead adopt a system of direct or indirect controls 
on  the  profitability  of  the  company  placing  the  medicinal  product  on  the  market.  There  can  be  no 
assurance  that  any  country  that  has  price  controls  or  reimbursement  limitations  for  biopharmaceutical 
products  will  allow  favorable  reimbursement  and  pricing  arrangements  for  any  of  Innate's  products. 
Historically, biopharmaceutical products launched in the European Union do not follow price structures 
of the United States and generally tend to have significantly lower prices. 

The Company believes that pricing pressures will continue and may increase, which may make it difficult 
for it to sell any of its product candidates that may be approved in the future at a price acceptable to the 
Company or any of its existing or future collaborators. 

Any of the Company's product candidates, if approved and commercialized, may fail to achieve market 
acceptance  by  physicians,  patients,  third-party  payors  or  the  medical  community  to  a  degree  that  is 
necessary for commercial success. 

Even if the medical community accepts a product as safe and efficacious for its indicated use, physicians 
may  choose  to  restrict  the  use  of  the  product  if  the  Company  is  unable  to  demonstrate  that,  based  on 
experience, clinical data, side-effect profiles and other factors, its drug is preferable to any existing drugs 
or treatments. The Company cannot predict the degree of market acceptance of any product candidate that 
will receive marketing authorization, which will depend on a number of factors, including, but not limited 
to: 

•

•

•

•

•

•

•

•

•

•

•

the demonstration of the clinical efficacy and safety of the drug; 

the approved labeling for the drug and any required warnings; 

prevalence and severity of adverse side effects; 

the advantages and disadvantages of the drug compared to alternative treatments; 

ease of the drug’s use; 

its ability to educate the medical community about the safety and effectiveness of the drug; 

the scope of any approval provided by the FDA or foreign regulatory authorities; 

publicity about its product or about competitive products; 

the  coverage  and  reimbursement  policies  of  government  and  commercial  third-party  payors 
pertaining to the drug; 

the market price of its drugs relative to competing treatments; and 

due to the rarity of orphan diseases, it could be difficult finding patients seeking treatment.

Poor  market  penetration  could  have  an  adverse  effect  on  the  Company's  business,  prospects,  financial 
condition and results of operations.

Innate's commercial experience is currently limited to Lumoxiti. Although Lumoxiti received a Marketing 
Authorization in 2018 in the United States, the level of sales in 2020 was lower than expected, leading 
Innate  to  make  the  decision  in  December  2020  to  return  the  commercial  rights  of  Lumoxiti  to 
AstraZeneca.  Beyond  the  financial  impacts,  the  direct  consequence  of  this  decision  was  the  immediate 
reduction  of  commercial  operations  in  the  Company's  U.S.  affiliate.  A  retrospective  analysis  identified 
two major causes: (i) a more complex patient access than expected due to geographic dispersion and (ii) 
the  global  pandemic  of  COVID-19.  The  COVID-19  pandemic  significantly  limited  interactions  with 
prescribing  physicians.  Moreover,  the  indolent  and  non-fatal  nature  of  hairy  cell  leukemia  in  the  short 
term  encouraged  physicians  to  delay  or  cancel  treatment  for  some  patients  during  the  pandemic.  This 
retrospective analysis of its commercial experience will help Innate Pharma capitalize on this experience 
for future registration and commercialization of its drug candidates.

Even  if  some  of  its  product  candidates  receive  marketing  authorization,  the  terms  of  such  approval, 
ongoing regulation and potential post-marketing restrictions or withdrawal from the market may limit 
how the drug may be marketed and may subject the Company to penalties for failure to comply with 
regulatory requirements, which could impair its ability to generate revenues. 

Even  if  any  of  its  product  candidates  receives  a  marketing  authorization,  such  approval  may  carry 
conditions  that  limit  the  market  for  the  drug  or  put  the  drug  at  a  competitive  disadvantage  relative  to 
alternative therapies. Regulators may limit the marketing of products to particular indications or patient 
populations.  Regulators  may  require  warning  labels,  and  drugs  with  warnings  are  subject  to  more 
restrictive marketing regulations than drugs without such warnings. These restrictions could make it more 
difficult to market any drug effectively. Marketing restrictions may reduce the revenue that the Company 
is able to obtain. 

Any  of  its  product  candidates  for  which  the  Company  obtains  marketing  authorization,  and  the 
manufacturing  processes,  post-approval  studies  and  measures,  labeling,  advertising  and  promotional 
activities for such products, among other things, will be subject to continual requirements of and review 
by the FDA, the EMA and other regulatory authorities. These requirements include submissions of safety 
and  other  post-marketing  information  and  reports,  registration  and  listing  requirements,  requirements 
relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of  records 
and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even 
if marketing authorization of a product candidate is granted, the approval may be subject to limitations on 
the indicated uses for which the product may be marketed or to the conditions of approval, including the 
FDA requirement to implement a risk evaluation and mitigation strategy to ensure that the benefits of a 
drug or biological product outweigh its risks. 

The FDA, EMA and other national authorities may also impose requirements for costly post-marketing 
studies or clinical trials and surveillance to monitor the safety or efficacy of a product, such as long-term 
observational studies on natural exposure. The FDA and other agencies, including the U.S. Department of 
Justice,  closely  regulate  and  monitor  the  post-approval  marketing  and  promotion  of  products  to  ensure 
that they are manufactured, marketed and distributed only for the approved indications and in accordance 
with  the  provisions  of  the  approved  labeling.  Later  discovery  of  previously  unknown  problems  with 
Innate's  product  candidates  or  with  manufacturing  processes,  including  adverse  events  of  unanticipated 
severity  or  frequency,  or  failure  to  comply  with  regulatory  requirements,  may  result  in  revisions  to  the 
approved labeling to add new safety information; imposition of post-market studies or clinical studies to 
assess  new  safety  risks,  or  the  imposition  of  distribution  or  other  restrictions  including  suspension  of 
production  and/or  distribution  and  withdrawal  of  regulatory  approvals.  Failure  to  comply  with  these 
requirements  may  lead  to  financial  penalties,  compliance  expenditures,  total  or  partial  suspension  of 
production  and/or  distribution,  product  seizure  or  detention,  refusal  to  permit  the  import  or  export  of 

27

products,  suspension  of  the  applicable  regulator’s  review  of  a  company’s  submissions,  enforcement 
actions,  product  recalls,  injunctions  and  even  criminal  prosecution,  any  of  which  could  materially  and 
adversely affect the Company's business, financial condition and results of operations. 

The Company's future growth depends, in part, on its ability to penetrate multiple markets, in which 
the Company would be subject to additional regulatory burdens and other risks and uncertainties. 

Innate's future profitability will depend, in part, on its ability to commercialize its product candidates, if 
approved,  in  markets  in  Europe,  the  United  States  and  other  countries  where  the  Company  maintains 
commercialization rights. If the Company commercializes its product candidates, if approved, in multiple 
markets, the Company would be subject to additional risks and uncertainties, including: 

•

•

•

•

•

•

•

•

•

•

•

foreign currency exchange rate fluctuations and currency controls; 

economic  weakness,  including  inflation,  or  political  instability  in  particular  economies  and 
markets; 

potentially adverse and/or unexpected tax consequences, including penalties due to the failure 
of tax planning or due to the challenge by tax authorities on the basis of transfer pricing and 
liabilities imposed from inconsistent enforcement; 

the  burden  of  complying  with  complex  and  changing  regulatory,  tax,  accounting  and  legal 
requirements, many of which vary between countries; 

different medical practices and customs in multiple countries affecting acceptance of drugs in 
the marketplace; 

differing payor reimbursement regimes, governmental payors or patient self-pay systems and 
price controls; 

tariffs, trade barriers, import or export licensing requirements or other restrictive actions; 

compliance  with  tax,  employment,  immigration  and  labor  laws  for  employees  living  or 
traveling abroad; 

workforce uncertainty in countries where labor unrest is common; 

reduced  or  loss  of  protection  of  intellectual  property  rights  in  some  foreign  countries,  and 
related prevalence of generic alternatives to therapeutics; and 

becoming subject to the different, complex and changing laws, regulations and court systems 
of  multiple  jurisdictions  and  compliance  with  a  wide  variety  of  foreign  laws,  treaties  and 
regulations. 

The conflict in Middle East and the Russia’s military intervention in Ukraine may affect regional stability 
and economic growth throughout Europe. These and other risks associated with international operations 
may  adversely  affect  Innate's  ability  to  attain  or  maintain  profitable  operations.  Future  sales  of  the 
Company's  product  candidates,  if  they  are  approved,  will  be  dependent  on  purchasing  decisions  of  and 
reimbursement  from  government  health  administration  authorities,  distributors  and  other  organizations. 
As a result of adverse conditions affecting the global economy and credit and financial markets, including 
disruptions  due  to  political  instability  or  otherwise,  these  organizations  may  defer  purchases,  may  be 
unable  to  satisfy  their  purchasing  or  reimbursement  obligations,  or  may  affect  milestone  payments  or 
royalties for monalizumab or any of Innate's product candidates that are approved for commercialization 
in  the  future.  Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate 
Pharma's business, prospects, financial condition and results of operations.

28

Even if its product candidates obtain regulatory approval, they will be subject to continuous regulatory 
review. 

If marketing authorization is obtained for any of its product candidates, the candidate will remain subject 
to  continuous  review,  and  therefore  authorization  could  be  subsequently  withdrawn  or  restricted.  The 
Company will be subject to ongoing obligations and oversight by regulatory authorities, including adverse 
event reporting requirements, marketing restrictions and, potentially, other post-marketing obligations, all 
of which may result in significant expense and limit its ability to commercialize such products. 

If there are changes in the application of legislation or regulatory policies, or if problems are discovered 
with a product or its manufacture of a product, or if the Company or one of its distributors, licensees or 
co-marketers  fails  to  comply  with  regulatory  requirements,  the  regulators  could  take  various  actions. 
These include imposing fines on us, imposing restrictions on the product or its manufacture and requiring 
Innate to recall or remove the product from the market. The regulators could also suspend or withdraw 
their marketing authorizations, requiring Innate to conduct additional clinical studies, change its product 
labeling or submit additional applications for marketing authorization. If any of these events occurs, its 
ability to sell such product may be impaired, and the Company may incur substantial additional expense 
to  comply  with  regulatory  requirements,  which  could  materially  adversely  affect  its  business,  financial 
condition and results of operations. 

Even if one of its product candidates has orphan drug designation, the Company may not be able to 
obtain any benefit from such designation. Furthermore, if a product is granted orphan drug exclusivity 
in the same indication for which the Company is developing lacutamab or its other product candidates 
that is granted orphan drug designation, the Company may not be able to have its product candidate 
approved by the applicable regulatory authority for a significant period of time. 

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs 
for  relatively  small  patient  populations  as  orphan  drugs.  Under  the  Orphan  Drug  Act,  the  FDA  may 
designate a product candidate as an orphan drug if it is a drug intended to treat a rare disease or condition, 
which is generally defined as a disease that affects a patient population of fewer than 200,000 people in 
the United States. In the European Union, the European Commission may designate a product candidate 
as  an  orphan  medicinal  product  if  it  is  a  medicine  for  the  diagnosis,  prevention  or  treatment  of  life-
threatening or very serious conditions that affects not more than five in 10,000 persons in the European 
Union,  or  it  is  unlikely  that  marketing  of  the  medicine  would  generate  sufficient  returns  to  justify  the 
investment needed for its development. Generally, if a product candidate with an orphan drug designation 
receives the first marketing approval for the indication for which it has such designation, the product is 
entitled  to  a  period  of  marketing  exclusivity,  which,  subject  to  certain  exceptions,  precludes  the  FDA 
from approving the marketing application of another drug for the same indication for that time period or 
precludes  the  EMA,  and  other  national  drug  regulators  in  the  European  Union,  from  accepting  the 
marketing  application  for  another  medicinal  product  for  the  same  indication.  The  applicable  period  is 
seven years in the United States and ten years in the European Union. The European Union period can be 
reduced to six years if a product no longer meets the criteria for orphan drug designation or if the product 
is profitable enough that market exclusivity is no longer justified. Orphan drug exclusivity may be lost in 
the United States if the FDA determines that the request for designation was materially defective or if the 
manufacturer is unable to assure sufficient quantity of the product to meet the needs of patients with the 
rare disease or condition. The granting of a request for orphan drug designation does not alter the standard 
regulatory requirements and process for obtaining marketing approval. 

Lacutamab has been granted orphan drug designation for cutaneous T cell lymphoma (CTCL) in Europe 
and  in  the  United  States,  and  the  Company  may  pursue  orphan  drug  designation  for  another  product 
candidate that the Company may develop in the future in the United States and/or Europe. However, there 
is no assurance the Company will be able to receive orphan drug designation for other product candidates 

29

that the Company may develop in the United States and/or Europe or for any other product candidate in 
any  jurisdiction.  Even  if  the  Company  is  successful  in  obtaining  orphan  drug  designation,  orphan  drug 
status  may  not  ensure  that  the  Company  has  market  exclusivity  in  a  particular  market.  Even  if  the 
Company  obtains  orphan  drug  exclusivity  for  any  of  its  product  candidates,  that  exclusivity  may  not 
effectively  protect  the  product  from  competition  because  exclusivity  can  be  suspended  under  certain 
circumstances.  In  the  United  States,  even  after  an  orphan  drug  is  approved,  the  FDA  can  subsequently 
approve another drug for the same condition if the FDA concludes that the later drug is clinically superior 
in  that  it  is  shown  to  be  safer,  more  effective  or  makes  a  major  contribution  to  patient  care.  In  the 
European Union, orphan exclusivity will not prevent a marketing authorization being granted for a similar 
medicinal product in the same indication if the new product is safer, more effective or otherwise clinically 
superior to the first product or if the marketing authorization holder of the first product is unable to supply 
sufficient  quantities  of  the  product.  In  addition,  if  another  product  is  granted  marketing  approval  and 
orphan drug exclusivity in the same indication for which the Company is developing a product candidate 
with orphan drug designation, the Company may not be able to have its product candidate approved by 
the applicable regulatory authority for a significant period of time. 

A fast track, breakthrough therapy or other designation by the FDA, or equivalent in other territories, 
may not actually lead to a faster development. 

The Company may seek fast track, breakthrough therapy or similar designation for its product candidates. 
If  a  product  is  intended  for  the  treatment  of  a  serious  or  life-threatening  condition  and  the  product 
demonstrates the potential to address unmet medical need for this condition, the sponsor may apply for 
FDA  fast  track  designation.  The  Company  has  received  fast  track  designation  in  the  U.S.  and  PRIME 
designation in the EU for lacutamab for the treatment of adult patients with relapsed or refractory Sézary 
Syndrome (SS) who have received at least two prior systemic therapies. 

Additionally, the Company may in the future seek a breakthrough therapy designation or an equivalent in 
other  territories  for  some  of  its  product  candidates  that  reach  the  regulatory  review  process.  A 
breakthrough therapy is a drug candidate that is intended, alone or in combination with one or more other 
drugs,  to  treat  a  serious  or  life-threatening  disease  or  condition,  and  that,  as  indicated  by  preliminary 
clinical  evidence,  may  demonstrate  substantial  improvement  over  existing  therapies  on  one  or  more 
clinically  significant  endpoints,  such  as  substantial  treatment  effects  observed  early  in  clinical 
development.  Drugs  designated  as  breakthrough  therapies  by  the  FDA  are  eligible  for  accelerated 
approval  and  increased  interaction  and  communication  with  the  FDA  designed  to  expedite  the 
development and review process. 

However,  these  designations  do  not  ensure  that  the  Company  will  experience  a  faster  development 
process,  review  or  approval  compared  to  conventional  FDA  procedures.  In  addition,  the  FDA  may 
withdraw a designation if it believes that the designation is no longer supported by data from its clinical 
development program. A designation alone does not guarantee qualification for the FDA’s priority review 
procedures. 

Priority review designation by the FDA, or the equivalent in other territories, may not lead to a faster 
regulatory  review  or  approval  process  and,  in  any  event,  does  not  assure  FDA  approval  of  Innate's 
product candidates. 

If the FDA determines that a product candidate offers major advances in treatment or provides a treatment 
where  no  adequate  therapy  exists,  the  FDA  may  designate  the  product  candidate  for  priority  review.  A 
priority review designation means that the goal for the FDA to review an application is six months, rather 
than the standard review period of 10 months. The Company may request priority review for its product 
candidates. The FDA has broad discretion with respect to whether or not to grant priority review status to 
a product candidate, so even if the Company believes a particular product candidate is eligible for such 

30

designation or status, the FDA may decide not to grant it. Moreover, a priority review designation does 
not necessarily mean a faster regulatory review process or necessarily confer any advantage with respect 
to approval compared to conventional FDA procedures. Receiving priority review from the FDA does not 
guarantee approval within the six-month review cycle or thereafter.

The Company is subject to healthcare laws and regulations which may require substantial compliance 
efforts  and  could  expose  Innate  to  criminal  sanctions,  civil  penalties,  contractual  damages, 
reputational harm and diminished profits and future earnings, among other penalties. 

Healthcare providers and third-party payors play a primary role in the recommendation and prescription 
of biologic products that are granted marketing approval. Arrangements with providers, consultants, third-
party payors and customers are subject to broadly applicable fraud and abuse, anti-kickback, false claims 
laws, transparency laws, patient data privacy laws, regulations and other healthcare laws and regulations 
that may constrain the business and/or financial arrangements. Restrictions under applicable federal and 
state healthcare laws and regulations, include the following:

•

•

•

the  U.S.  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  and  entities  from 
knowingly and willfully soliciting, offering, paying, receiving or providing remuneration, directly 
or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the 
purchase, order or recommendation of, any good or service, for which payment may be made, in 
whole or in part, under a federal healthcare program such as Medicare and Medicaid; 

the  U.S.  civil  and  criminal  false  claims  laws,  including  the  civil  False  Claims  Act,  and  civil 
monetary  penalties  laws,  which  prohibit  individuals  or  entities  from,  among  other  things, 
knowingly presenting, or causing to be presented, to the federal government, claims for payment 
that are false, fictitious or fraudulent or knowingly making, using or causing to made or used a 
false record or statement to avoid, decrease or conceal an obligation to pay money to the federal 
government;

the  U.S.  Health  Insurance  Portability  and  Accountability  Act  of  1996  (HIPAA),  which  created 
additional  federal  criminal  laws  that  prohibit,  among  other  things,  knowingly  and  willfully 
executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or 
making false statements relating to healthcare matters; 

• HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health 
Act, and their respective implementing regulations, including the Final Omnibus Rule published 
in  January  2013,  which  impose  obligations  on  covered  entities  and  their  business  associates, 
including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,  security  and 
transmission of individually identifiable health information; 

•

•

the  federal  transparency  requirements  known  as  the  federal  Physician  Payments  Sunshine  Act, 
under the Patient Protection and Affordable Care Act, as amended by the Health Care Education 
Reconciliation Act, or the ACA, which requires certain manufacturers of drugs, devices, biologics 
and medical supplies to report annually to the Centers for Medicare & Medicaid Services (CMS) 
within  the  United  States  Department  of  Health  and  Human  Services,  information  related  to 
payments and other transfers of value made by that entity to physicians and teaching hospitals, as 
well  as  ownership  and  investment  interests  held  by  physicians  and  their  immediate  family 
members; and 

analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims 
laws, which may apply to healthcare items or services that are reimbursed by non-governmental 
third-party payors, including private insurers. Some state laws require pharmaceutical companies 
to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant 

31

compliance  guidance  promulgated  by  the  federal  government  in  addition  to  requiring 
manufacturers  to  report  information  related  to  payments  to  physicians  and  other  health  care 
providers  or  marketing  expenditures.  Certain  state  laws  require  the  reporting  of  information 
relating  to  drug  and  biologic  pricing;  and  some  state  and  local  laws  require  the  registration  of 
pharmaceutical sales representatives. State and foreign laws also govern the privacy and security 
of health information in some circumstances, many of which differ from each other in significant 
ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Ensuring  that  Innate's  business  arrangements  with  third  parties  comply  with  applicable  healthcare  laws 
and  regulations  will  likely  be  costly.  It  is  possible  that  governmental  authorities  will  conclude  that  its 
business  practices  do  not  comply  with  current  or  future  statutes,  regulations  or  case  law  involving 
applicable fraud and abuse or other healthcare laws and regulations. If Innate Pharma's operations were 
found to be in violation of any of these laws or any other governmental regulations that may apply to us, 
the  Company  may  be  subject  to  significant  civil,  criminal  and  administrative  penalties,  damages,  fines, 
disgorgement,  imprisonment,  possible  exclusion  from  government  funded  healthcare  programs,  such  as 
Medicare and Medicaid, additional reporting requirements and oversight if the Company becomes subject 
to  a  corporate  integrity  agreement  or  similar  agreement  to  resolve  allegations  of  non-compliance  with 
these  laws,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  and 
curtailment of its operations, any of which could substantially disrupt its operations. If the physicians or 
other  providers  or  entities  with  whom  the  Company  expects  to  do  business  are  found  not  to  be  in 
compliance  with  applicable  laws,  they  may  be  subject  to  criminal,  civil  or  administrative  sanctions, 
including exclusions from government funded healthcare programs. Should any of these risks materialize, 
this  could  have  a  material  adverse  effect  on  its  business,  prospects,  financial  condition  and  results  of 
operations. 

European  data  collection  is  governed  by  restrictive  regulations  governing  the  collection,  use, 
processing and cross-border transfer of personal information. 

The Company may collect, process, use or transfer personal information from individuals located in the 
European Union in connection with its business, including in connection with conducting clinical studies 
in  the  European  Union.  The  collection  and  use  of  personal  health  data  in  the  European  Union  are 
governed  by  the  provisions  of  the  General  Data  Protection  Regulation  ((EU)  2016/679)  (GDPR).  This 
legislation  imposes  requirements  relating  to  having  legal  bases  for  processing  personal  information 
relating  to  identifiable  individuals  and  transferring  such  information  outside  of  the  European  Economic 
Area  (EEA),  including  to  the  United  States,  providing  details  to  those  individuals  regarding  the 
processing  of  their  personal  information,  keeping  personal  information  secure,  having  data  processing 
agreements  with  third  parties  who  process  personal  information,  responding  to  individuals’  requests  to 
exercise  their  rights  in  respect  of  their  personal  information,  reporting  security  breaches  involving 
personal data to the competent national data protection authority and affected individuals, appointing data 
protection  officers,  conducting  data  protection  impact  assessments  and  record-keeping.  The  GDPR 
applies across the European Economic Area (EEA) and, by virtue of the GDPR as it forms part of United 
Kingdom law, in a broadly uniform manner through section 3 of the European Union (Withdrawal) Act 
2018, or the UK GDPR, in the United Kingdom. However, the GDPR provides that EEA member states 
can  make  their  own  further  laws  and  regulations  to  introduce  specific  requirements  related  to  the 
processing  of  "special  categories  of  personal  data",  including  personal  data  related  to  health,  biometric 
data used for unique identification purposes and genetic information; as well as personal data related to 
criminal offenses or convictions – in the United Kingdom, the United Kingdom Data Protection Act 2018 
complements  the  UK  GDPR  in  this  regard.  This  fact  may  lead  to  greater  divergence  on  the  law  that 
applies  to  the  processing  of  such  data  types  across  the  EEA  and/or  United  Kingdom,  compliance  with 
which,  as  and  where  applicable,  may  increase  the  Company's  costs  and  could  increase  its  overall 

32

compliance risk. Such country-specific regulations could also limit its ability to collect, use and share data 
in  the  context  of  the  Company's  EEA  and/or  United  Kingdom  establishments  (regardless  of  where  any 
processing in question occurs), and/or could cause its compliance costs to increase, ultimately having an 
adverse impact on Innate's business and harming its business and financial condition. Failure to comply 
with the requirements of the GDPR and related national data protection laws of the member states of the 
European  Union  may  result  in  substantial  fines,  other  administrative  penalties  and  civil  claims  being 
brought against us, which could have a material adverse effect on Innate's business, prospects, financial 
condition  and  results  of  operations.  Moreover,  in  some  European  countries,  including  France,  there  are 
additional obligations applicable to the processing of personal data for the purpose of research in the field 
of healthcare and the hosting of personal health data must be carried out by specifically certified hosting 
service providers. Non-compliance with such additional rules as well as the absence or suspension of the 
appropriate certification of such hosting service provider may adversely affect Innate Pharma's business, 
or even lead to penalties related to breach of security of personal data.

Risks Related to Innate's Reliance on Third Parties 

The  Company  has  no  manufacturing  capabilities  and  relies  on  third-party  manufacturers  for  its 
product candidates. 

Innate  Pharma's  product  candidates  that  are  tested  during  its  preclinical  and  clinical  studies  are 
manufactured by third parties. The Company has no production capabilities and relies on third parties to 
manufacture its products. 

This  strategy  means  that  the  Company  does  not  directly  control  certain  key  aspects  of  its  product 
development, such as: 

•

•

•

•

the quality of the product manufactured; 

the delivery times for drugs for a given clinical trial; 

the clinical and commercial quantities that can be supplied; and 

compliance with applicable laws and regulations. 

Its  reliance  on  third-party  manufacturers  creates  risks  that  may  not  exist  if  the  Company  had  its  own 
manufacturing capabilities. These risks include: 

•

•

•

•

•

failure of third-party manufacturers to comply with regulatory and quality control standards; 

production of insufficient quantities; 

damage during transport and/or storage of its product candidates; 

breach of agreements by third-party manufacturers; and 

termination or non-renewal of the agreements for reasons beyond its control. 

Should  its  third-party  manufacturers  breach  their  obligations  or  should  the  Company  fails  to  renew  its 
contracts  with  them,  the  Company  cannot  guarantee  that  it  will  be  able  to  find  new  suppliers  within  a 
timeframe  and  under  conditions  that  would  not  be  detrimental.  The  Company  could  also  be  faced  with 
delays or interruptions in its supplies, which could result in a delay in the clinical trials and, ultimately, a 
delay in the commercialization of the product candidates that the Company is developing. For example, 
manufacturing issues, leading to out-of-specification product, can occur during a manufacturing campaign 
at the Contract Manufacturing Organization (CMO) in charge of the production of its product candidates.

33

Reproducing a batch of product is a lengthy and costly process and sometimes can lead to drug shortage 
that can in turn lead to a delay in the development of the candidate, or even an early stop of a clinical trial. 
This happened in the early clinical development of lacutamab and led to the decision to limit the number 
of patients in order to ensure drug supply for treated patients in the Phase 1 clinical study.

For example, in November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill 
Solutions  GmbH),  the  subcontractor  in  charge  of  the  fill-and-finish  manufacturing  operations  of 
lacutamab,  unilaterally  decided  to  withdraw  the  certificates  of  conformance  of  all  clinical  batches 
produced  at  their  facilities,  including  the  lacutamab  batch  used  for  the  TELLOMAK  Phase  2  clinical 
study  assessing  lacutamab  in  multiple  indications.  Impletio  Wirkstoffabfüllung  GmbH  decided  to 
withdraw the certificates of conformance even though the compliance of its manufacturing site with Good 
Manufacturing Practices had been confirmed by two on-site inspections performed by the Austrian Health 
Agency before and after the Company began to work with them. 

The  transfer  of  the  manufacturing  process  to  another  contract  manufacturing  organization  took  a  few 
months and came with additional costs but allowed Innate to have a conform batch in the middle of 2020 
and  to  resume  the  enrollment  and  treatment  of  patients  in  the  clinical  trials  after  getting  Regulatory 
Agencies' approval. During this period of time, the TELLOMAK trial was on partial or full hold in the 
United States, Spain, Germany and Italy.

Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's  business, 
prospects, financial condition and results of operations. 

The  Company  is  reliant  upon  third  parties  to  manufacture  and  supply  components  of  certain 
substances necessary to manufacture its product candidates. 

The Company is reliant on several third-party CMOs for the manufacture and supply of components and 
substances for all of the product candidates the Company is developing. In addition, certain component 
materials  are  currently  available  from  a  single  supplier,  or  a  small  number  of  suppliers.  The  Company 
cannot be sure that these suppliers will remain in business, or that they will not be purchased by one of its 
competitors or another company that is not interested in continuing to manufacture these materials for us. 
The Company cannot assure that, if required, the Company will be able to identify alternate sources with 
the  desired  scale  and  capability  and  establish  relationships  with  such  sources.  A  loss  of  any  CMO  or 
component supplier and delay in establishing a replacement could delay Innate's clinical development and 
regulatory approval process. 

Its production costs may be higher than the Company currently estimates. 

Innate's  product  candidates  are  manufactured  according  to  manufacturing  best  practices  applicable  to 
drugs for clinical trials and to specifications approved by the applicable regulatory authorities. If any of 
its products were found to be non-compliant, the Company would be required to manufacture the product 
again, which would entail additional costs and may prevent delivery of the product to patients on time. 

Other risks inherent in the production process may have the same effect, such as: 

•

•

•

•

•

contamination of the controlled atmosphere area; 

unusable premises and equipment; 

new regulatory requirements requiring a partial and/or extended stop to the production unit to 
meet the requirements; 

unavailable qualified personnel; 

power failure of extended duration; and 

34

•

logistical error. 

Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  its  business,  prospects, 
financial condition and results of operations. 

The Company relies on third parties to supply key materials used in its research and development, to 
provide services to Innate and to assist with clinical studies. 

The Company makes considerable use of third-party suppliers for the key materials used in its business. 
The failure of third-party suppliers to comply with regulatory standards could result in the imposition of 
sanctions  on  the  Company.  These  sanctions  could  include  fines,  injunctions,  civil  penalties,  refusal  by 
regulatory  organizations  to  grant  approval  to  conduct  clinical  trials  or  marketing  authorization  for  its 
products,  delays,  suspension  or  withdrawal  of  approvals,  license  revocation,  seizure  or  recalls  of  its 
products, operating restrictions and legal proceedings. Furthermore, the presence of non-conformities, as 
detected in regulatory toxicology studies, could result in delays in the development of one or more of its 
product candidates and would require further tests to be financed. Although the Company is involved in 
establishing  the  protocols  for  the  production  of  these  materials,  the  Company  does  not  control  all  the 
stages of production and cannot guarantee that the third parties will fulfil their contractual and regulatory 
obligations.  In  particular,  a  partner’s  failure  to  comply  with  protocols  or  regulatory  constraints,  or 
repeated delays by a partner, could compromise the development of its products or limit its liability. Such 
events could also inflate the product development costs incurred by us. 

The  Company  also  uses  third  parties  to  provide  certain  services  such  as  scientific,  medical  or  strategic 
consultancy services. These service providers are generally selected for their specific expertise, as is the 
case  with  the  academic  partners  with  whom  the  Company  collaborates.  To  build  and  maintain  such  a 
network under acceptable terms, the Company faces intense competition. Such external collaborators may 
terminate,  at  any  time,  their  involvement.  The  Company  can  exert  only  limited  control  over  their 
activities.  The  Company  may  not  be  able  to  obtain  the  intellectual  property  rights  to  the  product 
candidates  or  technologies  developed  under  collaboration,  research  and  license  agreements  under 
acceptable terms or at all. Moreover, its scientific collaborators may assert intellectual property rights or 
other rights beyond the terms of their engagement. 

Finally,  the  Company  uses  third-party  investigators  to  assist  with  conducting  clinical  trials.  All  clinical 
trials  are  subject  to  strict  regulations  and  quality  standards.  Should  any  of  these  risks  materialize,  this 
could  have  a  material  adverse  effect  on  its  business,  prospects,  financial  condition  and  results  of 
operations. 

The  Company  and  its  collaborators  rely  on  third  parties  to  conduct  some  of  its  preclinical  clinical 
studies and perform other clinical development tasks. If these third parties do not successfully carry out 
their contractual duties, meet expected deadlines or comply with regulatory requirements, it may not be 
possible  to  obtain  regulatory  approval  for,  or  commercialize,  its  product  candidates,  and  its  business 
could be substantially harmed. 

The Company has relied upon and plans to continue to rely upon third parties to conduct clinical studies 
of its product candidates or product candidates that the Company has licensed to partners. For example, 
under its license and collaboration agreements with AstraZeneca, AstraZeneca is responsible for a number 
of  clinical  studies  relating  to  monalizumab  and  IPH5201,  which  are  subject  to  such  agreements.  In 
addition, the Company and its collaborators are responsible for and are supporting several clinical studies 
that are sponsored by academic or research institutions, known as investigator-sponsored trials, as is the 
case for the clinical study assessing IPH5301, which is sponsored by Institut Paoli-Calmettes and for the 
clinical study assessing lacutamab in PTCL, sponsored by the Lymphoma Study Association (LYSA). By 
definition, the financing, design and conduct of an investigator-sponsored trial are the sole responsibility 
of  the  sponsor,  and  the  Company  or  its  collaborators,  as  applicable,  have  limited  control  over  these 

35

aspects of these clinical trials, or the timing and reporting of the data from these trials. The Company and 
its collaborators also depend on independent clinical investigators and CROs to conduct clinical studies. 
CROs  may  also  assist  in  the  collection  and  analysis  of  data.  There  are  a  limited  number  of  CROs  that 
have the expertise to run clinical studies of its product candidates. Identifying, qualifying and managing 
performance of third-party service providers can be difficult and time consuming and can cause delays in 
its development programs. These investigators and CROs are not Innate's employees, and the Company is 
not  able  to  control,  other  than  by  contract,  the  amount  of  resources,  including  the  amount  of  time,  that 
they devote to Innate's product candidates and clinical studies. If the investigators sponsoring studies of 
its product candidates, independent investigators participating in clinical studies that Innate Pharma or its 
collaborators  are  sponsoring  or  CROs  fail  to  devote  sufficient  resources  to  its  clinical  studies  and 
development  of  its  product  candidates  or  product  candidates  the  Company  has  licensed  to  others,  or  if 
their  performance  is  substandard,  it  may  delay  or  compromise  the  prospects  for  approval  and 
commercialization of any product candidates that the Company or its collaborators develop. In addition, 
the  use  of  third-party  service  providers  requires  Innate  to  disclose  its  proprietary  information  to  these 
parties, which could increase the risk that this information will be misappropriated, and the Company may 
not be able to obtain adequate remedies for such disclosure or misappropriation. Further, the FDA, EMA 
and other regulatory authorities require that the Company complies with standards, commonly referred to 
as Good Clinical Practice (GCP), and other local legal requirements, including data privacy regulations, 
for conducting, recording and reporting clinical trials to assure that data and reported results are credible 
and  accurate  and  that  the  rights,  integrity  and  confidentiality  of  clinical  trial  subjects  are  protected.  If 
clinical investigators or CROs fail to meet their obligations to Innate or comply with GCP procedures or 
other applicable legal requirements, the data generated in these trials may be deemed unreliable, and the 
FDA, EMA or comparable foreign regulatory authorities may require Innate to perform additional studies 
before  approving  Innate  Pharma's  marketing  applications.  The  Company  cannot  assure  that  upon 
inspection by a given regulatory authority, such regulatory authority will determine that all of its clinical 
trials comply with GCP regulations. 

In  addition,  Innate's  clinical  studies  must  be  conducted  with  product  produced  under  current  Good 
Manufacturing Practice (cGMP) regulations. The Company's failure to comply with these regulations may 
require  the  Company  to  repeat  clinical  trials,  which  would  delay  the  regulatory  approval  process.  If 
clinical investigators or CROs do not successfully carry out their contractual duties or obligations or meet 
expected  deadlines,  if  they  need  to  be  replaced  or  if  the  quality  or  accuracy  of  the  data  they  obtain  is 
compromised  due  to  the  failure  to  adhere  to  Innate's  protocol  or  regulatory  requirements,  or  for  other 
reasons,  its  clinical  trials  or  those  of  its  collaborators  may  be  extended,  delayed  or  terminated,  and  the 
Company  or  its  collaborators  may  not  be  able  to  obtain  regulatory  approval  for  or  successfully 
commercialize its product candidates. As a result, its results of operations and the commercial prospects 
for  its  product  candidates  would  be  harmed,  its  costs  could  increase  and  its  ability  to  generate  revenue 
could be delayed.

Manufacturing  facilities  and  clinical  investigational  sites  are  subject  to  significant  government 
regulations  and  approvals,  and  if  Innate's  or  its  partners’  third-party  manufacturers  fail  to  comply 
with these regulations or maintain these approvals, its business could be materially harmed. 

Innate's  third-party  manufacturers  are  subject  to  ongoing  regulation  and  periodic  inspection  by  national 
authorities, including the EMA, FDA and other regulatory bodies to ensure compliance with cGMP, when 
producing  batches  of  its  product  candidates  for  clinical  trials.  CROs  and  other  third-party  research 
organizations  must  also  comply  with  Good  Laboratory  Practices  (GLP)  when  carrying  out  regulatory 
toxicology studies. Any failure to follow and document the Company's or third parties' adherence to such 
GMP  and  GLP  regulations  or  other  regulatory  requirements  may  lead  to  significant  delays  in  the 

36

availability of products for commercial sale or clinical trials, may result in the termination of or a hold on 
a clinical trial, or may delay or prevent filing or approval of marketing applications for its products. 

Failure to comply with applicable regulations could also result in national authorities, the EMA, FDA or 
other applicable regulatory authorities taking various actions, including: 

•

•

•

•

•

•

•

•

•

•

levying fines and other civil penalties; 

imposing consent decrees or injunctions; 

requiring Innate to suspend or put on hold one or more of its clinical trials; 

suspending or withdrawing regulatory approvals; 

delaying or refusing to approve pending applications or supplements to approved applications; 

requiring  Innate  Pharma  to  suspend  manufacturing  activities  or  product  sales,  imports  or 
exports; 

requiring Innate to communicate with physicians and other customers about concerns related 
to actual or potential safety, efficacy and other issues involving its products; 

mandating product recalls or seizing products; 

imposing operating restrictions; and 

seeking criminal prosecutions. 

Any of the foregoing actions could be detrimental to Innate's reputation, business, financial condition or 
operating results. Furthermore, its key suppliers may not continue to be in compliance with all applicable 
regulatory requirements, which could result in its failure to produce its products on a timely basis and in 
the  required  quantities,  if  at  all.  In  addition,  before  any  additional  products  would  be  considered  for 
marketing  authorization  in  Europe,  the  United  States  or  elsewhere,  its  suppliers  will  have  to  pass  an 
inspection by the applicable regulatory agencies. The Company is dependent on its suppliers’ cooperation 
and  ability  to  pass  such  inspections,  and  the  inspections  and  any  necessary  remediation  may  be  costly. 
Failure  to  pass  such  inspections  by  Innate  Pharma  or  any  of  its  suppliers  would  affect  its  ability  to 
commercialize its product candidates in Europe, the United States or elsewhere. Should any of these risks 
materialize,  this  could  have  a  material  adverse  effect  on  the  Company's  business,  prospects,  financial 
condition and results of operations. For example, in November 2019, Impletio Wirkstoffabfüllung GmbH 
(formerly  known  as  Rentschler  Fill  Solutions  GmbH),  the  subcontractor  in  charge  of  the  fill-and-finish 
manufacturing operations of lacutamab, unilaterally decided to withdraw the certificates of conformance 
of all clinical batches produced at their facilities, including the lacutamab batch used for the TELLOMAK 
Phase 2 clinical study assessing lacutamab in multiple indications, which resulted in partial or full holds 
in a number of countries, which have since been resolved.

The  Company  depends  upon  its  existing  collaboration  partners,  AstraZeneca,  Sanofi  and  other  third 
parties,  and  may  depend  upon  future  collaboration  partners  to  commit  to  the  research,  development, 
manufacturing and marketing of its drugs. 

The  Company  has  significant  collaborations  with  AstraZeneca  for  the  development  of  monalizumab, 
IPH5201 and other product candidates. The Company also collaborates with Sanofi for the development 
of  IPH6101/SAR'579,  IPH6401/SAR’514,  IPH62  and  IPH67  another  program  in  solid  tumors,  and  the 
Company may enter into additional collaborations for other of its product candidates or technologies in 
development. The Company cannot control the timing or quantity of resources that its existing or future 
collaborators will dedicate to research, preclinical and clinical development, manufacturing or marketing 
of its products. Innate's collaborators may not perform their obligations according to its expectations or 

37

standards of quality. Innate Pharma's collaborators could terminate its existing agreements for a number 
of  reasons,  including  that  they  may  have  other,  higher  priority  products  in  development  or  because  its 
partnered  programs  may  no  longer  be  a  priority  for  them.  If  any  of  the  Company's  collaboration 
agreements  were  to  be  terminated,  the  Company  could  encounter  significant  delays  in  developing  its 
product  candidates,  lose  the  opportunity  to  earn  any  revenues  Innate  expected  to  generate  under  such 
agreements, incur unforeseen costs and suffer damage to the reputation of its product, product candidates 
and as a company generally. 

In  order  to  optimize  the  launch  and  market  penetration  of  certain  of  its  future  product  candidates,  the 
Company may enter into distribution and marketing agreements with pharmaceutical industry leaders. For 
these  product  candidates,  the  Company  would  not  market  its  products  alone  once  they  have  obtained 
marketing authorization. The risks inherent in entry into these contracts are as follows: 

•

•

•

•

the negotiation and execution of these agreements is a long process that may not result in an 
agreement being signed or that can delay the development or commercialization of the product 
candidate concerned; 

these agreements are subject to cancellation or non-renewal by its collaborators or may not be 
fully complied with by its collaborators; 

in the case of a license granted by us, the Company loses control of the development of the 
product candidate licensed; in such cases the Company would have only limited control over 
the means and resources allocated by its partner for the commercialization of its product; and 

collaborators  may  not  properly  obtain,  maintain,  enforce  or  defend  Innate's  intellectual 
property or proprietary rights or may use its proprietary information in such a way as to invite 
litigation  that  could  jeopardize  or  invalidate  its  proprietary  information  or  expose  the 
Company to potential litigation. 

Should  any  of  these  risks  materialize,  or  should  the  Company  fails  to  find  suitable  collaborators,  this 
could  have  a  material  adverse  effect  on  its  business,  prospects,  financial  condition  and  results  of 
operations. 

The late-stage development and marketing of its product candidates may partially depend on its ability 
to establish collaborations with major biopharmaceutical companies. 

In  order  to  develop  and  market  some  of  its  product  candidates,  the  Company  relies  on  collaboration, 
research  and  license  agreements  with  pharmaceutical  companies  to  assist  Innate  in  the  development  of 
product  candidates  and  the  financing  of  their  development.  For  its  most  advanced  clinical  product 
candidate,  monalizumab,  the  Company  entered  into  an  agreement  with  AstraZeneca,  in  part  because  of 
their  late-stage  development  and  marketing  capabilities.  As  the  Company  identifies  new  product 
candidates, Innate Pharma will determine the appropriate strategy for development and marketing, which 
may result in  the need to establish collaborations with major biopharmaceutical companies. Innate may 
also enter into agreements with institutions and universities to participate in its other research programs 
and to share intellectual property rights. 

The  Company  may  fail  to  find  collaboration  partners  and  to  sign  new  agreements  for  its  other  product 
candidates  and  programs.  The  competition  for  partners  is  intense,  and  the  negotiation  process  is  time-
consuming  and  complex.  Any  new  collaboration  may  be  on  terms  that  are  not  optimal  for  us,  and  the 
Company may not be able to maintain any new collaboration if, for example, development or approval of 
a product candidate is delayed, sales of an approved product candidate do not meet expectations or the 
collaborator  terminates  the  collaboration.  Any  such  collaboration,  or  other  strategic  transaction,  may 
require Innate to incur non-recurring or other charges, increase Innate's near- and long-term expenditures 
and  pose  significant  integration  or  implementation  challenges  or  disrupt  its  management  or  business. 

38

These transactions would entail numerous operational and financial risks, including exposure to unknown 
liabilities; disruption of Innate's business and diversion of its management’s time and attention in order to 
manage a collaboration or develop acquired products, product candidates or technologies; incurrence of 
substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs; higher 
than  expected  collaboration,  acquisition  or  integration  costs;  write-downs  of  assets  or  goodwill  or 
impairment charges; increased amortization expenses; difficulty and cost in facilitating the collaboration 
or combining the operations and personnel of any acquired business; and impairment of relationships with 
key suppliers, manufacturers or customers of any acquired business due to changes in management and 
ownership and the inability to retain key employees of any acquired business. Accordingly, although there 
can  be  no  assurance  that  the  Company  will  undertake  or  successfully  complete  any  transactions  of  the 
nature described above, any transactions that the Company does complete may be subject to the foregoing 
or  other  risks  and  have  a  material  and  adverse  effect  on  its  business,  financial  condition,  results  of 
operations and prospects. Conversely, any failure to enter any additional collaboration or other strategic 
transaction 
the  development  and  potential 
commercialization  of  its  product  candidates  and  have  a  negative  impact  on  the  competitiveness  of  any 
product candidate that reaches market. 

that  would  be  beneficial 

to  Innate  could  delay 

The  Company  does  not  and  will  not  have  access  to  all  information  regarding  its  product  candidates 
that  are  subject  to  collaboration  and  license  agreements.  Consequently,  its  ability  to  inform  its 
shareholders about the status of product candidates that are subject to these agreements, and its ability 
to make business and operational decisions, may be limited. 

Innate  does  not  and  will  not  have  access  to  all  information  regarding  its  product  candidates  that  are 
subject  to  its  license  and  collaboration  agreements  with  AstraZeneca,  Sanofi  and  other  third  parties, 
including  potentially  material  information  about  clinical  trial  design,  execution  and  timing,  safety  and 
efficacy, clinical trial results, regulatory affairs, manufacturing, marketing and other areas known by its 
collaborators. In addition, the Company has confidentiality obligations under its collaboration and license 
agreements. Therefore, its ability to keep its shareholders informed about the status of product candidates 
subject to such agreements will be limited by the degree to which its collaborators keep Innate informed 
and allow Innate Pharma to disclose information to the public or provide such information to the public 
themselves.  If  its  collaborators  do  not  inform  Innate  about  its  product  candidates  subject  to  agreements 
with  them,  the  Company  may  make  operational  and  investment  decisions  that  the  Company  would  not 
have  made  had  the  Company  been  fully  informed,  which  may  have  an  adverse  impact  on  its  business, 
prospects, financial condition and results of operations. 

Risks Related to Innate Pharma's Financial Position and Capital Needs

The  Company  has  incurred  and  may  in  the  future  incur  significant  operational  losses  related  to  its 
research and development activities. 

The  Company  has  incurred  net  losses  in  each  year  since  its  inception  except  for  the  years  ended 
December 31, 2016 and 2018. Innate's net income (loss) was €(7.6) million and €(58.1) million for the 
years ended December 31, 2023 and 2022, respectively. Substantially all of its net losses resulted from 
costs incurred in connection with its development programs and from selling, general and administrative 
expenses associated with its ongoing operations. The Company expects to incur significant expenses and 
operating losses for the foreseeable future.

The Company had one product, Lumoxiti, that has received regulatory approval for sale or has generated 
revenues  from  commercial  sales,  and  none  of  its  other  product  candidates  have  received  regulatory 
approval. Unless this happens, the likelihood and amount of its future operational losses will depend on 
several  factors,  including  the pace and amount of its future expenditures in connection with its product 

39

candidates  and  development  programs  and  its  ability  to  obtain  funding  through  milestone  or  royalty 
payments  under  its  license  and  collaboration  agreements,  equity  or  debt  financings,  strategic 
collaborations  and  government  grants  and  tax  credits.  The  Company  expects  that  its  main  source  of 
income for the near- and medium-term will be: 

•

•

payments received under its license and collaboration agreements with third parties, including 
AstraZeneca and Sanofi; and 

government grants and research tax credits. 

The  interruption  of  one  or  more  of  those  sources  of  income  could  have  a  material  adverse  effect  on 
Innate's business, prospects, financial condition and results of operations.

The Company's ability to be profitable in the future will depend on its ability to generate revenue from 
sales  relating  to  its  product  candidates,  if  approved,  and  its  ability  to  obtain  regulatory  approval  for 
marketing its product candidates. If its product candidates receive regulatory approval, its future revenues 
will  depend  upon  the  size  of  any  markets  in  which  its  product  candidates  have  received  approval,  and 
market acceptance, reimbursement from third-party payors and market share. Any of these factors could 
have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial  condition  and  results  of 
operations. 

The  Company  may  need  to  raise  additional  funding  to  complete  the  development  and  any 
commercialization of its product candidates, which may not be available on acceptable terms, or at all, 
and  failure  to  obtain  this  necessary  capital  when  needed  may  force  it  to  delay,  limit  or  terminate  its 
product development efforts or other operations. 

Innate Pharma is currently advancing its product candidates through preclinical and clinical development, 
and  anticipates  relying  on  partners  as  the  Company  advances  them.  Innate  currently  retains  the  full 
development  and  marketing  rights  to  lacutamab,  IPH5301  and  IPH6501  and  may  retain  rights  to 
additional  proprietary  product  candidates  in  the  future.  The  development  of  immunotherapy  product 
candidates  is  expensive,  and  Innate  expects  its  research  and  development  expenses  to  increase  as  the 
Company  advances  its  product  candidates  through  clinical  studies  and  regulatory  approvals.  If  clinical 
studies are successful and if Innate obtains regulatory approval for product candidates that the Company 
develops,  Innate  expects  to  incur  commercialization  expenses  before  these  product  candidates  are 
marketed and sold. 

The Company anticipates that its expenses will increase substantially if and as it: 

•

•

•

•

•

•

•

•

continues  its  research,  preclinical  and  clinical  development  of  its  product  candidates  if  its 
current collaboration partners cease their collaborations with us; 

expands the scope of its current clinical studies for its product candidates; 

initiates additional preclinical, clinical or other studies for its product candidates; 

further develops manufacturing processes for its product candidates; 

changes or adds additional manufacturers or suppliers; 

seeks  regulatory  and  marketing  authorizations  for  its  product  candidates  that  successfully 
complete clinical studies; 

establishes a sales, marketing and distribution infrastructure to commercialize any product for 
which the Company may obtain marketing authorization; 

seeks  to  identify  and  validate  additional  product  candidates  that  may  result  in  additional 
preclinical, clinical or other product studies; 

40

•

•

•

•

•

•

acquires or in-license agreements or other product candidates and technologies; 

makes milestone or other payments under any in-license agreements;

maintains, protects, defends and expands its intellectual property portfolio; 

attracts and retains new and existing skilled personnel; 

creates  additional  infrastructure  to  support  its  operations  as  a  public  company  in  the  United 
States following the completion of the October 2019 global offering; and 

experiences any delays or encounters issues with any of the above. 

As  of  December  31,  2023,  the  Company  had  cash,  cash  equivalents,  short-term  investments  and  non-
current  financial  assets  of  €102.3  million.  The  Company  believes  its  cash,  cash  equivalents,  short-term 
investments  and  non-current  financial  assets,  together  with  its  cash  flow  from  operations,  will  be 
sufficient to fund its operations for the next two years. However, in order to complete the development 
process,  obtain  regulatory  approval  and,  if  approved,  commercialize  its  product  candidates  that  the 
Company  is  developing  in-house,  including  lacutamab,  IPH5301  and  IPH6501;  develop  its  proprietary 
technology; and develop a pipeline of additional product candidates, the Company will require additional 
funding.  Innate's  existing  resources  may  not  be  sufficient  to  cover  any  additional  financing  needs,  in 
which case new funding would be required. See “—the Company has incurred and may in the future incur 
significant  operational  losses  related  to  its  research  and  development  activities.”  The  conditions  and 
arrangements  for  such  new  financing  would  depend,  among  other  factors,  on  economic  and  market 
conditions that are beyond its control, including the current volatility in the capital markets.

Any additional fundraising efforts may divert Innate's management from their day-to-day activities, which 
may  adversely  affect  the  Company's  ability  to  develop  and  commercialize  its  product  candidates.  In 
addition, the Company cannot guarantee that future financing will be available in sufficient amounts or on 
terms  acceptable  to  us,  if  at  all.  Under  French  law,  Innate's  share  capital  may  be  increased  only  with 
shareholders’ approval at an extraordinary general shareholders’ meeting on the basis of a report from the 
Executive Board. In addition, the French Commercial Code imposes certain limitations on Innate's ability 
to price certain offerings of its share capital without preferential subscription rights (droit préférentiel de 
souscription), which limitation may prevent Innate from successfully completing any such offering. 

Moreover,  the  terms  of  any  financing  may  adversely  affect  the  holdings  or  the  rights  of  Innate's 
shareholders, and the issuance of additional securities, whether equity or debt, by us, or the possibility of 
such  issuance,  may  cause  the  market  price  of  its  ordinary  shares  or  the  ADSs  to  decline.  The  sale  of 
additional  equity  or  convertible  securities  would  dilute  its  shareholders.  The  Company  may  seek  funds 
through arrangements with collaborative partners or otherwise at an earlier stage of product development 
than otherwise would be desirable, and the Company may be required to relinquish rights to some of its 
technologies  or  product  candidates  or  otherwise  agree  to  terms  unfavorable  to  Innate  Pharma,  any  of 
which  may  have  a  material  adverse  effect  on  its  business,  prospects,  financial  condition  and  results  of 
operations. 

If the Company needs and is unable to obtain funding on a timely basis, the Company may be required to 
significantly  curtail,  delay  or  discontinue  one  or  more  of  its  research  or  development  programs  or  the 
commercialization  of  any  product  or  product  candidate,  or  the  Company  may  be  unable  to  expand  its 
operations or otherwise capitalize on its business opportunities as desired, which could impair its growth 
prospects.  Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's 
business, prospects, financial condition and results of operations. 

41

The  terms  of  Innate's  loans  agreements  with  Société  Générale,  BNP  Paribas  and  certain  other  loan 
obligations place restrictions on its operating and financial flexibility. 

In July 2017, the Company entered into a loan and security agreement with Société Générale (the “Loan 
Agreement”)  in  order  to  finance  the  construction  of  its  future  headquarters.  The  Loan  Agreement  is 
secured by collateral in the form of financial instruments valued at €15.2 million held at Société Générale. 
As of December 31, 2023, Innate Pharma had drawn down €15.2 million under the Loan Agreement. The 
Loan  Agreement  subjects  Innate  to  a  covenant  to  maintain  a  minimum  balance  of  its  total  cash,  cash 
equivalents  and  current  and  non-current  financial  assets  as  of  each  fiscal  year  end  at  least  equal  to  the 
amount of outstanding principal under the Loan Agreement. Compliance with this covenant may limit its 
flexibility in operating its business and its ability to take actions that might be advantageous to Innate and 
its  shareholders.  For  example,  if  the  Company  fails  to  meet  its  minimum  cash  covenant  and  Innate  is 
unable  to  raise  additional  funds  or  obtain  a  waiver  or  other  amendment  to  the  Loan  Agreement,  Innate 
Pharma may be required to delay, limit, reduce or terminate certain of its clinical development efforts. 

Additionally,  Innate  may  be  required  to  repay  the  entire  amount  of  outstanding  indebtedness  under  the 
Loan Agreement in cash if the Company fails to stay in compliance with its covenant or suffer some other 
event of default under the Loan Agreement. Under the Loan Agreement, an event of default will occur if, 
among  other  things,  Innate  fails  to  make  payments  under  the  Loan  Agreement  or  Innate  breaches  its 
covenant  under  the  Loan  Agreement.  The  Company  may  not  have  enough  available  cash  or  be  able  to 
raise additional funds through equity or debt financings to repay such indebtedness at the time any such 
event of default occurs. In that case, Innate may be required to delay, limit, reduce or terminate its clinical 
development efforts or grant rights to others to develop and market product candidates that the Company 
would  otherwise  prefer  to  develop  and  market  itself.  Société  Générale  could  also  exercise  its  rights  as 
collateral agent to take possession and dispose of the collateral securing the loan for its benefit. Innate's 
business, financial condition and results of operations could be substantially harmed as a result of any of 
these events. 

On January 5, 2022, the Company announced that it had obtained €28.7 million in non-dilutive financing 
in  the  form  of  two  State  Guaranteed  Loans  from  Société  Générale  (€20.0  million)  and  BNP  Paribas 
(€8.7 million). The Company received the funds related to these two loans on December 27 and 30, 2021, 
respectively. Both loans have an initial maturity of one year with an option to extend to five years. They 
are  90%  guaranteed  by  the  French  government  as  part  of  the  package  of  measures  put  in  place  by  the 
French  government  to  support  companies  during  the  COVID-19  pandemic.  The  effective  interest  rate 
applied to these contracts is 0.5%, which is the contractual rate for repayment within one year.

On August 2022, the Company requested the extension repayment of the non-dilutive financing of €28.7 
million obtained in December 2021 in the form of two State Guaranteed Loans ( “PGE”), respectively, for 
20.0 and 8.7 million euros for an additional period of five years starting in 2022 and including a one-year 
grace  period.  Consequently,  the  Company  has  obtained  agreements  from  Société  Générale  and  BNP 
Paribas. The effective interest rates applied to these contracts during the additional period are 1.56% and 
0.95% for Société Générale and BNP Paribas loans, respectively, excluding insurance and guarantee fees, 
with an amortization exemption for the entire year 2023. During this grace period, the Company will only 
be liable for the payment of interest and the guarantee fees, with amortization of the two loans starting in 
2024 over a period of four years.

If Innate does not achieve its product development or commercialization objectives in the timeframes 
Innate expects, the Company may not receive product revenue or milestone or royalty payments, and 
Innate Pharma may not be able to conduct its operations as planned. 

Innate has received and expects to continue to receive payments from its collaborators when the Company 
satisfies  certain  pre-specified  milestones  in  its  licensing  or  collaboration  agreements.  Innate  Pharma 
currently depends to a large degree on these milestone payments from its existing collaborators in order to 
fund  its  operations,  and  Innate  may  enter  into  new  collaboration  agreements  that  also  provide  for 
milestone  payments.  For  example,  the  Company  has  granted  options  to  license  or  acquire  intellectual 
property  rights  in  certain  of  its  programs  to  its  collaborators  which,  if  exercised,  will  result  in  up-front 
option exercise fees and, assuming Innate meets all specified development, clinical, regulatory and sales 
milestones,  could  result  in  substantial  milestone  payments.  These  milestone  payments  are  generally 
dependent  on  the  accomplishment  of  various  scientific,  clinical,  regulatory,  sales  and  other  product 
development objectives, and the successful or timely achievement of many of these milestones is outside 
of its control, in part because some of these activities are being or will be conducted by its collaborators. 
If Innate or its collaborators fail to achieve the applicable milestones, Innate Pharma may not receive such 
milestone payments. A failure to receive any such milestone payment may cause Innate to: 

•

•

•

•

•

•

delay, reduce or terminate certain research and development programs; 

reduce headcount; 

raise funds through additional equity or convertible debt financings that could be dilutive to its 
shareholders and holders of its ADSs; 

obtain  funds  through  collaboration  agreements  that  may  require  Innate  to  assign  rights  to 
technologies or products that Innate would have otherwise retained;

sign  new  collaboration  or  license  agreements  that  may  be  less  favorable  than  those  the 
Company would have obtained under different circumstances; and 

consider strategic transactions or engaging in a joint venture with a third party. 

In  addition,  although  Innate  may  be  eligible  to  receive  an  aggregate  of  approximately  $3.9  billion  in 
future  contingent  payments  from  existing  collaboration  agreements  and  any  license  agreements  that 
become  effective  upon  the  exercise  by  its  collaborators  of  options  to  license  future  product  candidates, 
there is no guarantee that the Company will receive any contingent payments or that its collaborators will 
exercise any options to license or acquire additional intellectual property rights in any of its programs. If 
its  collaborators  decide  not  to  exercise  such  options  with  respect  to  a  program,  the  Company  will  not 
receive the up-front option exercise fee and will not be eligible to receive any of the related commercial, 
development,  royalty  or  other  milestone  payments.  Even  if  its  collaborators  exercise  such  options  with 
respect to a particular program, Innate Pharma may never achieve the related milestones for any number 
of reasons. The failure to receive milestone or royalty payments and the occurrence of any of the events 
above may have a material adverse impact on Innate's business, prospects, financial condition and results 
of operations. 

The  revenues  generated  from  its  collaboration  and  license  agreements  have  contributed  and  are 
expected to contribute a large portion of its revenue for the foreseeable future. 

The  Company  has  entered  into  collaboration  and  license  agreements  with  pharmaceutical  companies, 
including AstraZeneca and Sanofi. The upfront payments and milestones received from its partners were 
€31.6 million, €56.9 million and €10.0 million for the years ended December 31, 2023, 2022 and 2021, 
respectively. 

43

Innate  also  enhances  its  research  efforts  by  establishing  collaborations  with  academic  or  non-profit 
research  institutions  and  other  biopharmaceutical  companies.  The  participation  in  these  collaborations 
may generate revenue and funding in the form of operating grants or the reimbursement of research and 
development expenses. 

Innate  Pharma  may  not  be  able  to  renew  or  maintain  its  license  agreements  or  collaborative  research 
contracts or may be unable to sign new agreements with new collaborators on reasonable terms or at all. 
The early termination of a contract, the non-renewal of a contract or its inability to find new collaborators 
would  adversely  affect  its  business.  Should  any  of  these  risks  materialize,  this  could  have  an  adverse 
effect on Innate's business, prospects, financial condition and results of operations. 

The Company benefits from tax credits in France that could be reduced or eliminated. 

As  a  French  biopharmaceutical  company,  Innate  benefits  from  certain  tax  advantages,  including  the 
Research  Tax  Credit  (Crédit  Impôt  Recherche),  which  is  a  French  tax  credit  aiming  at  stimulating 
research  and  development.  The  Research  Tax  Credit  is  calculated  based  on  Innate's  claimed  amount  of 
eligible research and development expenditures in France and represented €9.7 million, €7.9 million and 
€10.3  million  for  the  years  ended  December  31, 2023,  2022  and  2021,  respectively.  The  Research  Tax 
Credit is a source of financing to Innate that could be reduced or eliminated by the French tax authorities 
or by changes in French tax law or regulations. 

The  Research  Tax  Credit  can  be  offset  against  French  corporate  income  tax  due  by  the  company  with 
respect to the year during which the eligible research and development expenditures have been made. The 
portion of tax credit in excess which is not being offset, if any, represents a receivable against the French 
Treasury which can in principle be offset against the French corporate income tax due by the company 
with respect to the three following years. The remaining portion of tax credit not being offset upon expiry 
of such a period may then be refunded to the company. 

As  soon  as  the  Company  qualifies  as  small-  and  medium-size  business,  the  French  Treasury  refunds 
immediately (meaning that, in practice, Innate can receive the refund during the year following the year in 
which the eligible research and development expenditures are made) the Research Tax Credit claims. If 
the Company does not qualify for this status, the Research Tax Credit claims will be reimbursed within 
the expiry of a period of three years. The history of the Company's status and of the incomes related to the 
Research  Tax  Credit  is  detailed  in  the  Notes  to  financial  statements,  section  2),  paragraph  q)  of  the 
present document.

The French tax authorities, with the assistance of the Higher Education and Research Ministry, may audit 
each  research  and  development  program  in  respect  of  which  a  Research  Tax  Credit  benefit  has  been 
claimed and assess whether such program qualifies in their view for the Research Tax Credit benefit. The 
French tax authorities may challenge Innate's eligibility for, or its calculation of, certain tax reductions or 
deductions  in  respect  of  its  research  and  development  activities  (and  therefore  the  amount  of  Research 
Tax  Credit  claimed),  or  the  accelerated  reimbursement  allowed  for  small-  and  medium-size  businesses 
and the Company's credits may be reduced, which would have a negative impact on its revenue and future 
cash flows.

Furthermore,  the  French  Parliament  may  decide  to  eliminate,  or  to  reduce  the  scope  or  the  rate  of,  the 
Research Tax Credit benefit, either of which it could decide to do at any time. If Innate fails to receive 
future Research Tax Credit amounts or if its calculations are challenged, even if Innate Pharma complies 
with  the  current  requirements  in  terms  of  documentation  and  eligibility  of  its  expenditure,  its  business, 
prospects, financial condition and results of operations could be adversely affected. 

44

The Company may be unable to carry forward existing tax losses. 

Innate has accumulated tax loss carry forwards of €483.6 million as of December 31, 2023. Applicable 
French law provides that, for fiscal years ending after December 31, 2012, the use of these tax losses is 
limited  to  €1.0  million,  plus  50%  of  the  portion  of  net  earnings  exceeding  this  amount.  The  unused 
balance of the tax losses in application of such rule can be carried forward to future fiscal years, under the 
same conditions and without time restriction. There can be no assurance that future changes to applicable 
tax law and regulation will not eliminate or alter these or other provisions in a manner unfavorable to us, 
which  could  have  an  adverse  effect  on  Innate's  business,  prospects,  financial  condition,  cash  flows  or 
results of operations. 

Innate's business may be exposed to foreign exchange risks. 

The Company incurs some of its expenses, and derives certain of its revenues, in currencies other than the 
euro. In particular, as Innate expands its operations and conducts additional clinical studies in the United 
States,  Innate  will  incur  additional  expenses  in  U.S.  dollars.  As  a  result,  Innate  is  exposed  to  foreign 
currency  exchange  risk  as  its  results  of  operations  and  cash  flows  are  subject  to  fluctuations  in  foreign 
currency exchange rates. 

The Company currently does not engage in hedging transactions to protect against uncertainty in future 
exchange rates between particular foreign currencies and the euro. Therefore, an unfavorable change in 
the  value  of  the  euro  against  the  U.S.  dollar  could  have  a  negative  impact  on  its  revenue  and  earnings 
growth.  Innate  cannot  predict  the  impact  of  foreign  currency  fluctuations,  and  foreign  currency 
fluctuations in the future may adversely affect its financial condition, results of operations and cash flows. 
The  ADSs  being  offered  in  the  U.S.  offering  are  quoted  in  U.S.  dollars  on  the  Nasdaq,  while  Innate's 
ordinary  shares  trade  in  euro  on  Euronext  Paris.  Innate's  financial  statements  are  prepared  in  euro. 
Therefore, fluctuations in the exchange rate between the euro and the U.S. dollar will also affect, among 
other matters, the value of Innate's ordinary shares and ADSs. 

Under  Innate's  license  and  collaboration  agreements  with  AstraZeneca,  the  payments  the  Company 
receives  are  in  U.S.  dollars.  The  level  of  completion  of  the  operations  covered  by  this  collaboration 
agreement  is  based  on  the  costs  converted  at  the  historical  exchange  rate.  The  effects  of  reevaluation 
therefore have no impact on the technical progress used for revenue recognition. Consequently, there may 
be a difference between the level of completion that would take into account the last known rate and the 
level of completion as calculated. This difference could result in a future exchange gain or loss.

Moreover, in the future, Innate could generate part of its sales in the United States and part in Europe and 
could  therefore  be  subject  to  an  unfavorable  euro/dollar  exchange  rate.  Therefore,  for  example,  an 
increase in the value of the euro against the U.S. dollar could be expected to have a negative impact on its 
revenue and earnings growth as U.S. dollar revenue and earnings, if any, would be translated into euro at 
a reduced value. The Company could also sign contracts denominated in other currencies, which would 
increase its exposure to currency risk. In accordance with Innate's business decisions, its exposure to this 
type of risk could change depending on: 

•

•

•

•

the currencies in which Innate receives its revenues; 

the  currencies  chosen  when  agreements  are  signed,  such  as  licensing  agreements,  or  co-
marketing or co-development agreements; 

the location of clinical trials on product candidates; and 

its policy for insurance cover. 

45

At present, Innate has not put any specific hedging arrangements in place to address these risks. Should 
any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  its  business,  prospects, 
financial condition and results of operations. 

Changes to U.S. and non-U.S. tax laws could materially adversely affect Innate Pharma.

The Company is unable to predict what tax law may be proposed or enacted in the future or what effect 
such  changes  would  have  on  its  business,  but  such  changes,  to  the  extent  they  are  brought  into  tax 
legislation, regulations, policies or practices, could affect its effective tax rates in the future in countries 
where it has operations and could have an adverse effect on its overall tax rate in the future, along with 
increasing the complexity, burden and cost of tax compliance. The Company urges its shareholders and 
holders  of  its  ADSs  to  consult  with  their  legal  and  tax  advisors  with  respect  to  the  potential  tax 
consequences of investing in or holding Innate's ordinary shares or ADSs. 

Tax authorities may disagree with Innate's positions and conclusions regarding certain tax positions, 
resulting in unanticipated costs, taxes or non-realization of expected benefits. 

A  tax  authority  may  disagree  with  tax  positions  that  the  Company  has  taken,  which  could  result  in 
increased  tax  liabilities.  For  example,  the  French  tax  authorities,  the  U.S.  Internal  Revenue  Service  or 
another  tax  authority  could  challenge  Innate's  allocation  of  income  by  tax  jurisdiction  and  the  amounts 
paid  between  its  affiliated  companies  pursuant  to  its  intercompany  arrangements  and  transfer  pricing 
policies,  including  amounts  paid  with  respect  to  its  intellectual  property  development.  Similarly,  a  tax 
authority could assert that the Company is subject to tax in a jurisdiction where Innate believes it has not 
established a taxable connection, often referred to as a “permanent establishment” under international tax 
treaties, and such an assertion, if successful, could increase the Company's expected tax liability in one or 
more jurisdictions. A tax authority may take the position that material income tax liabilities, interest and 
penalties are payable by us, in which case, the Company expects that it might contest such assessment. 
Contesting such an assessment may be lengthy and costly, and if Innate was unsuccessful in disputing the 
assessment, the result could increase its anticipated effective tax rate.

In 2022 and 2023, the Company went through tax inspections, in particular one tax inspection from the 
French tax authorities relating to 2018 to 2021 fiscal years resulted in an adjustment of €1.4 million. The 
full details of the outcomes of this inspection are provided in the Notes to financial statements, section 13) 
of the present document.

Risks Related to Innate Pharma's Organization and Operations 

In  the  past  there  have  been  material  weaknesses  in  the  Company's  internal  control  over  financial 
reporting  and  if  Innate  Pharma  is  unable  to  maintain  effective  internal  controls  over  financial 
reporting, the accuracy and timeliness of its financial reporting may be adversely affected, which could 
hurt its business and/or lessen investor confidence. 

The  Company  must  maintain  effective  internal  control  processes  over  financial  reporting  in  order  to 
accurately report its results of operations and financial condition on a timely basis. A company’s internal 
control  over  financial  reporting  is  a  process  designed  by,  or  under  the  supervision  of,  a  company’s 
principal executive and principal financial officers, or persons performing similar functions, and effected 
by  a  company’s  Executive  Board,  management  and  other  personnel  to  provide  reasonable  assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  in  accordance 
with generally accepted accounting principles. 

As  a  public  company  listed  in  the  United  States,  the  Sarbanes-Oxley  Act  requires,  among  other  things, 
that the Company assess the effectiveness of its internal control over financial reporting as of the end of 

46

each fiscal year. However, Innate's independent registered public auditor has not been required to attest to 
the effectiveness of its internal controls over financial reporting for as long as the Company is an EGC, 
i.e., an “emerging growth company,” pursuant to the Jumpstart Our Business Startups Act of 2012 (JOBS 
Act).  For  more  information,  see  “Item  3.D  –  Risk  Factors—The  Company  is  an  “emerging  growth 
company” under the JOBS Act and is able to avail itself of reduced disclosure requirements applicable to 
emerging  growth  companies,  which  can  make  its  ordinary  shares  ADSs  less  attractive  to  investors.  We 
may lose this status from December 31, 2024 and will therefore incur additional expenses.

In this context, in order to comply with Section 404(a) of the Sarbanes-Oxley Act within the prescribed 
timeframe, and over the last five years, the Company has reinforced its internal control processes and has 
implemented a standard and more robust Information System including an Enterprise Resource Planning 
(ERP)  tool  supporting  the  production  and  the  management  of  its  financial  information.  Some  material 
weaknesses were identified as of December 31, 2020 and 2022. 

Under standards established by the Public Company Accounting Oversight Board, a material weakness is 
a deficiency or combination of deficiencies in internal control over financial reporting, such that there is a 
reasonable possibility that a material misstatement in Innate's annual or interim financial statements will 
not be prevented or detected and corrected on a timely basis. These deficiencies concerned, respectively, 
process and controls relating to the processing of manual entries and significant and unusual transactions, 
and controls aimed at preventing or detecting material errors in the classification and presentation of the 
consolidated  financial  statements,  as  well  as  in  the  corresponding  disclosures  and  the  recording  of  all 
subcontracting expenses over the correct period. We took steps to address these material weaknesses and 
implemented  remediation  plans.  For  a  discussion  about  these  remediation  measures,  see  "Item  15. 
Controls and Procedures" of this Annual Report.

The  Company's  management  carried  out  an  evaluation  of  the  effectiveness  of  its  internal  control  at  the 
end  of  the  year  ended  December  31,  2023.  Management  concluded  that,  as  of  December  31,  2023,  the 
Company's  internal  control  over  financial  reporting  was  effective  to  provide  reasonable  assurance 
regarding  the  reliability  of  its  financial  reporting  and  the  preparation  of  its  financial  statements  for 
external purposes. See "Item 15. Controls and Procedures" of this Annual Report.

The Company cannot give any assurance that it will be able to maintain the appropriate level of control to 
prevent future material weaknesses. 

In  addition,  once  it  loses  EGC  status,  the  Company  will  have  to  comply  with  Section  404(b)  of  the 
Sarbanes-Oxley Act. The rules governing the standards that must be met for the Company's management 
to assess our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act 
are  complex  and  require  significant  documentation,  testing  and  possible  remediation.  These  stringent 
standards require that the Company's audit committee be advised and regularly updated on management’s 
review  of  internal  control  over  financial  reporting.  To  comply  with  this  obligation,  the  Company  must 
maintain  an  extensive  framework  of  internal  control  over  financial  reporting,  that  needs  to  be  regularly 
updated and tested. This process is time-consuming, costly, and complicated. The Company's independent 
registered  public  accounting  firm  will  be  required  to  attest  to  the  effectiveness  of  our  internal  controls 
over financial reporting beginning with our annual report following the date on which we are no longer an 
“emerging growth company.” The management of the Company may not be able to effectively and timely 
implement  controls  and  procedures  that  adequately  respond  to  the  increased  regulatory  compliance  and 
reporting requirements that are now applicable to the Company as a public company listed in the United 
States.

If the Company does not succeed in maintaining the appropriate level of internal control, it could result in 
material misstatements in its financial statements, result in the loss of investor confidence in the reliability 

47

of its financial statements and subject it to regulatory scrutiny and sanctions, which in turn could harm the 
market value of its ordinary shares and ADSs. 

Innate's internal computerized systems, or those of its third-party contractors or consultants, may fail 
or suffer security breaches and be subject to malicious intent or cyberattack, which could result in a 
material disruption of its product development programs and in its operations in general. 

The Company has implemented a security policy that is intended to secure its data against impermissible 
access and to preserve the integrity and confidentiality of the data. To monitor these aspects, the 
Company set up a dedicated governance structure. See "Item 16K.—Cybersecurity." Despite the 
implementation of such processes and measures, Innate's internal computer systems and those of its third-
party contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, 
natural disasters, terrorism, war, telecommunication and electrical failures and other sources. Moreover, 
part of the Company's information system is “cloud”-based and thus is not fully under its control.

In addition, Innate's research and development facility and headquarters in Luminy, France, is located in 
an area that may be more susceptible to wildfires. If Innate's facility or computer systems are damaged by 
fire despite the fire prevention and data archiving measures it has put in place, it could suffer financial 
losses and delays in its operations. 

If such an event were to occur and cause interruptions in Innate's operations, it could result in a material 
disruption  of  its  programs  and  more  generally  of  its  operations.  For  example,  the  loss  of  clinical  study 
data  for  Innate's  product  candidates  could  result  in  delays  in  its  regulatory  approval  efforts  and 
significantly increase its costs to recover or reproduce the lost data. To the extent that any disruption or 
security breach results in a loss of or damage to Innate's data or applications or other data or applications 
relating to its technology or product candidates or inappropriate disclosure of confidential or proprietary 
information, it could incur liabilities, including penalties under data privacy laws such as the GDPR and 
other  regulations,  and  the  further  development  of  its  product  candidates  could  be  delayed.  Even  if  the 
Company has not experienced any cyber breach to date, should any of these risks materialize, this could 
have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial  condition  and  results  of 
operations. 

The Company has subscribed to insurance covering "cyber" and fraud. This insurance may be insufficient 
with  regard  to  the  level  of  financial,  legal,  operational  and  reputational  impacts  that  could  arise  from  a 
disruption or a break of the Company information systems. 

The Company may encounter difficulties in managing the Company development and support changes 
in its strategy, which could disrupt its operations. 

The  opportunities  taken,  the  decisions  made,  the  successes  and  failures  of  Innate's  research  and 
development programs and its operations in general can have significant impacts on its workforce and the 
scope of its operations.

The  strong  growth  in  the  Company's  headcount  over  the  last  five  years  as  well  as  the  recent 
transformations  of  the  Company,  in  particular  in  connection  with  the  acquisition  in  2018  of  Lumoxiti, 
Innate's first commercial product, have been accompanied by structural changes within the organization 
and  its  operating modes.  Such rapid changes may lead to a deterioration in working conditions and the 
leave of employees, which could lead to a loss of knowledge and expertise, a decrease in the performance 
of Innate's operations and therefore a reduced level of achievement of its objectives. 

Moreover, in December 2020, the decision of returning Lumoxiti commercial rights to AstraZeneca was 
followed  by  an  immediate  reduction  of  Innate's  commercial  operations  and  headcounts  in  the  United 
States. Although the Company gained some experience in the late stage development and marketing and 
commercialization of pharmaceutical products, such experience was short and may not have resulted in a 

48

sufficient  acquisition  of  skills  to  anticipate  and  tackle  the  marketing  and  commercialization  of  Innate's 
other drug candidates. 

In addition, in order to support the development of the Company and changes in strategy, the Company 
must continue to implement and improve its management and operational and financial systems, adapt its 
facilities and recruit and train qualified personnel. Due to Innate's limited financial resources, it may not 
be able to effectively manage the development of Innate's business, which could result in weaknesses in 
its  infrastructure,  operational  errors,  loss  of  business  opportunities,  loss  of  employees  and  reduced 
productivity  of  remaining  employees.  The  Company  may  also  experience  difficulties  in  recruiting, 
training and retaining additional qualified personnel, particularly in key positions. Added to this is the fact 
that the Company is located in Marseille and is competing with other locations that potential recruits may 
find more attractive.

[If the Company were to acquire assets or companies, the success of such an acquisition would depend on 
its  capacity  to  carry  out  such  acquisitions  and  to  integrate  such  assets  or  companies  into  its  existing 
operations. The implementation of such a strategy could impose significant constraints, including: 

•

•

•

human  resources:  recruiting,  integrating,  training,  managing,  motivating  and  retaining  a 
growing number of employees; 

financial  and  management  system  resources:  identification  and  management  of  appropriate 
financing and management of its financial reporting systems; and 

infrastructure:  expansion  or  transfer  of  its  laboratories  or  the  development  of  its  information 
technology system. 

If the Company is unable to manage such changes or has difficulty integrating any acquisitions, it could 
have a material adverse effect on its business, prospects, financial condition and results of operations.]

The Company relies on certain independent organizations, partners, advisors and consultants to 
provide certain services and needs to hire new employees and expand its use of service providers. 

As of December 31, 2023, the Company had 179 employees. As Innate's development plans and strategies 
develop,  Innate  Pharma  may  need  additional  managerial,  operational,  marketing,  financial  and  other 
personnel. 

The  Company  currently  relies,  and  for  the  foreseeable  future  will  continue  to  rely,  in  part  on  certain 
independent organizations, partners, advisors and consultants to provide certain services. There can be no 
assurance  that  the  services  of  these  independent  organizations,  partners,  advisors  and  consultants  will 
continue  to  be  available  to  Innate  on  a  timely  basis  when  needed,  or  that  Innate  can  find  qualified 
replacements. In addition, if Innate Pharma is unable to effectively manage its outsourced activities or if 
the quality or accuracy of the services provided by consultants is compromised for any reason, its clinical 
trials may be extended, delayed or terminated, and it may not be able to obtain regulatory approval of its 
product candidates or otherwise advance its business. There can be no assurance that Innate will be able 
to  manage  its  existing  consultants  or  find  other  competent  outside  contractors  and  consultants  on 
economically reasonable terms, if at all. 

If the Company is not able to effectively expand its organization by hiring new employees and expanding 
its groups of consultants and contractors, it may not be able to successfully implement the tasks necessary 
to  further  develop  and  commercialize  its  product  candidates  and,  accordingly,  may  not  achieve  its 
research, development and commercialization goals.

The Company depends on qualified management personnel, and its business could be harmed if Innate 
loses key personnel and cannot attract new personnel. 

Innate's ability to retain key persons in its organization and to recruit qualified personnel is crucial for its 
success. In particular,  its  success depends heavily on its ability to retain key people in its organization, 
including key scientific and medical personnel. 

Should  the  Company  be  unable  to  retain  the  individuals  who  form  its  team  of  key  managers  and  key 
scientific  advisors,  it  could  have  a  material  adverse  effect  on  its  business  and  development  and  could 
consequently affect its business, prospects, financial condition and results of operations. 

Innate  Pharma  will  need  to  recruit  qualified  scientific  and  medical  personnel  to  carry  out  its  clinical 
studies  and  expand  into  new  areas  that  require  specialized  skills,  such  as  regulatory  matters,  marketing 
and  manufacturing.  Innate  competes  with  other  companies,  research  organizations  and  academic 
institutions  in  recruiting  and  retaining  highly  qualified  scientific,  technical  and  management  personnel. 
Competition  for  such  personnel  is  very  intense  in  the  biopharmaceutical  field,  and  there  can  be  no 
assurance that the Company will be successful in attracting or retaining such personnel, and the failure to 
do so could harm its operations and its growth prospects. Should any of these risks materialize, this could 
have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial  condition  and  results  of 
operations. 

Innate's  Research  and  Development  facility  and  Headquarters  in  Luminy,  France,  are  exposed  to 
forest fires.

The Company's Research and Development facility and Headquarters in Luminy, France, are exposed to 
forest  fires.  Luminy  is  an  area  on  the  outskirts  of  Marseille,  composed  in  part  of  undeveloped  hills 
covered with shrubs and pine trees. It is also located next to a natural park entirely covered by the same 
type of Mediterranean vegetation. Summers are hot and dry, and this type of vegetation is prone to forest 
fires. Indeed, in September 2016, such a forest fire came relatively close to inhabited areas, including the 
Company's facilities, where employees had to remain confined for several hours.

In order to prevent the risk of fire, fire prevention measures are implemented, such as pruning shrubs in 
the  surrounding  green  areas  and  implementing  a  maintenance  plan  for  fire-fighting  equipment.  In 
addition, computer data backup and archiving measures are implemented, allowing the regularly backed-
up data to be stored on the premises of a specialized service provider. In addition, rare biological material 
used  by  the  Company  has  been  identified,  duplicated  and  stored  at  other  sites,  at  the  premises  of 
specialized service providers.

However,  these  measures  do  not  guarantee  that  another  forest  fire  would  not  damage  the  Company's 
premises in Luminy, which would result in financial losses, development delays of various durations or 
even the suspension of the Company's activities.

The Company may use hazardous chemicals and biological materials in its business, and any claims 
relating  to  improper  handling,  storage  or  disposal  of  these  materials  could  be  time-consuming  and 
costly. 

Innate's research and development processes involve the controlled use of hazardous materials, including 
chemicals,  biological  and  radioactive  materials.  The  Company  cannot  eliminate  the  risk  of  accidental 
contamination or discharge and any resultant injury from these materials. Innate also handles genetically 
recombined material, genetically modified species and pathological biological samples. Consequently, in 
France  and  in the jurisdictions where the Company conducts clinical trials, it is subject to environment 
and safety laws and regulations governing the use, storage, handling, discharge and disposal of hazardous 
materials,  including chemical and biological products and radioactive materials. The Company imposes 
preventive and protective measures for the protection of its workforce and waste control management in 

50

accordance with applicable laws, including part four of the French Labor Code, relating to occupational 
health and safety. 

In France, the Company is required to comply with a number of national, regional and local legislative or 
regulatory  provisions  regarding  radiation  and  hazardous  materials,  including  specific  regulations 
regarding the use, handling and storage of radioactive materials and the potential exposure of employees 
to hazardous materials and radiation. Innate must also comply with French regulations concerning the use 
and handling of genetically modified organisms (GMOs) in confined spaces. 

If Innate fails to comply with applicable regulations, it could be subject to fines and may have to suspend 
all  or  part  of  its  operations.  Compliance  with  environmental,  health  and  safety  regulations  involves 
additional costs, and Innate Pharma may have to incur significant costs to comply with future laws and 
regulations in relevant jurisdictions. Compliance with environmental laws and regulations could require 
Innate  to  purchase  equipment,  modify  facilities  and  undertake  considerable  expenses.  The  Company 
could  be  liable  for  any  inadvertent  contamination,  injury  or  damage,  which  could  negatively  affect  its 
business, although the Company has subscribed to an insurance policy covering certain risks inherent to 
its business. 

Product  liability  and  other  lawsuits  could  divert  Innate's  resources,  result  in  substantial  liabilities, 
reduce the commercial potential of its product candidates and damage its reputation. 

Given that the Company develops therapeutic products intended to be tested on humans and used to treat 
humans, the risk that Innate Pharma may be sued on product liability claims is inherent in its business. 
Side  effects  of,  or  manufacturing  defects  in,  products  that  the  Company  develops  could  result  in  the 
deterioration of a patient’s condition, injury or even death. For example, its liability could be sought by 
patients  participating  in  the  clinical  trials  in  the  context  of  the  development  of  the  therapeutic  products 
tested and unexpected side effects resulting from the administration of these products. Once a product is 
approved for sale and commercialized, the likelihood of product liability lawsuits increases. Criminal or 
civil  proceedings  might  be  filed  against  Innate  by  patients,  regulatory  authorities,  biopharmaceutical 
companies  and  any  other  third  party  using  or  marketing  Innate's  products.  These  actions  could  include 
claims resulting from acts by Innate's partners, licensees and subcontractors, over which the Company has 
little  or  no  control.  These  lawsuits  may  divert  Innate's  management  from  pursuing  its  business  strategy 
and may be costly to defend. In addition, if the Company is held liable in any of these lawsuits, it may 
incur  substantial  liabilities,  may  be  forced  to  limit  or  forgo  further  commercialization  of  the  affected 
products and may suffer damage to its reputation. 

Although the clinical study process is designed to identify and assess potential side effects, it is always 
possible that a drug, even after regulatory approval, may exhibit unforeseen side effects. If any of Innate's 
product  candidates  were  to  cause  adverse  side  effects  during  clinical  studies  or  after  approval  of  the 
product candidate, the Company may be exposed to substantial liabilities. Physicians and patients may not 
comply with any warnings that identify known potential adverse effects and patients who should not use 
Innate's product candidates. 

The Company has obtained liability insurance coverage for each of its clinical studies in compliance with 
local  legislation  and  rules.  In  the  United  States,  Innate's  aggregate  insurance  coverage  for  its  ongoing 
clinical studies is limited to €10.0 million per year and in the aggregate. Innate's insurance coverage may 
not be sufficient to cover any expenses or losses the Company may suffer. Moreover, insurance coverage 
is  becoming  increasingly  expensive,  and,  in  the  future,  Innate  Pharma  may  not  be  able  to  maintain 
insurance  coverage  at  a  reasonable  cost  or  in  sufficient  amounts  to  protect  itself  against  losses  due  to 
liability. On occasion, large judgments have been awarded in class action lawsuits based on drugs that had 
unanticipated  side  effects.  The  cost  of  any  product  liability  litigation  or  other  proceedings,  even  if 
resolved in Innate's favor, could be substantial. A successful product liability claim, or series of claims, 

51

brought against Innate could cause Innate's share price to decline and, if judgments exceed its insurance 
coverage, could decrease its cash and adversely affect its business. 

To date, the Company is covered by a product liability insurance with a coverage amount of €10 million 
per year in the aggregate. If Innate is the subject of a successful product liability claim that exceeds the 
limits  of  any  insurance  coverage  Innate  Pharma  obtains,  the  Company  would  incur  substantial  charges 
that  would  adversely  affect  its  earnings  and  require  the  commitment  of  capital  resources  that  might 
otherwise be available for the development and commercial launch of its product programs. Should any of 
these risks materialize, this could have a material adverse effect on Innate's business, prospects, financial 
condition and results of operations. 

Innate Pharma's employees may engage in misconduct or other improper activities, including violating 
applicable regulatory standards and requirements, engaging in insider trading or violating the terms of 
their confidentiality agreements, which could significantly harm Innate's business. 

The Company is exposed to the risk of employee fraud or other misconduct. Misconduct by employees 
could  include  intentional  failure  to  comply  with  legal  requirements  or  the  requirements  of  national 
authorities,  the  EMA,  FDA  and  other  government  regulators;  failure  to  provide  accurate  information  to 
applicable government authorities; failure to comply with fraud and abuse and other healthcare laws and 
regulations in the United States, Europe and elsewhere; and failure to report financial information or data 
accurately  or  disclose  unauthorized  activities  to  us.  In  particular,  sales,  marketing  and  business 
arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent 
fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict 
or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer 
incentive  programs  and  other  business  arrangements.  Employee  misconduct  could  also  involve  the 
improper use of, including trading on, information obtained in the course of clinical studies, which could 
result in regulatory sanctions and serious harm to Innate's reputation. Innate Pharma has a Code of Ethics 
that applies to all employees and consultants, and other policies and charters, but it is not always possible 
to identify and deter employee misconduct, and the precautions it takes to detect and prevent this activity 
may  be  ineffective  in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  Innate  from 
governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a  failure  to  comply  with  these 
laws or regulations. 

In order to protect its proprietary technology and processes, the Company relies in part on confidentiality 
agreements  with  its  partners,  employees,  consultants,  outside  scientific  collaborators  and  sponsored 
researchers, and other advisors. These agreements may not effectively prevent disclosure of confidential 
information  and  may  not  provide  an  adequate  remedy  in  the  event  of  unauthorized  disclosure  of 
confidential  information.  Costly  and  time-consuming  litigation  could  be  necessary  to  enforce  and 
determine the scope of Innate's proprietary rights, and failure to obtain or maintain trade secret protection 
could adversely affect its competitive business position. Should any of these risks materialize, this could 
have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial  condition  and  results  of 
operations. 

The  Company  may  acquire  businesses  or  products  in  the  future,  and  Innate  may  not  realize  the 
benefits of such acquisitions. 

Although Innate's current strategy involves continuing to grow its business internally, the Company may 
grow  externally  through  selective  acquisitions  of  complementary  products  and  technologies,  or  of 
companies with such assets. If such acquisitions were to become necessary or attractive in the future, the 
Company  may  not  be  able  to  identify  appropriate  targets  or  make  acquisitions  under  satisfactory 
conditions, in particular, satisfactory price conditions. In addition, Innate Pharma may be unable to obtain 
the  financing  for  these  acquisitions  under  favorable  conditions  and  could  be  led  to  finance  these 

52

acquisitions  using  cash  that  could  be  allocated  to  other  purposes  in  the  context  of  existing  operations. 
Innate  may  encounter  numerous  difficulties  in  developing,  manufacturing  and  marketing  any  new 
products resulting from an acquisition that delays or prevents Innate from realizing their expected benefits 
or  enhancing  its  business.  The  Company  cannot  assure  you  that,  following  any  such  acquisition,  the 
Company  will  achieve  the  expected  synergies  to  justify  the  transaction,  which  could  have  a  material 
adverse effect on Innate's business, financial conditions, earnings and prospects. 

Climate  change  or  legal,  regulatory  or  market  measures  to  address  climate  change  may  negatively 
affect Innate's business and results of operations.

Climate  change  presents  risks  to  Innate's  operations,  including  the  potential  for  additional  regulatory 
requirements  and  associated  costs,  and  the  potential  for  more  frequent  and  severe  weather  events  and 
water  availability  challenges  that  may  impact  Innate's  facilities  and  those  of  Innate's  suppliers.  Natural 
disasters and extreme weather conditions, such as a hurricane, tornado, earthquake, wildfire or flooding, 
may pose physical risks to Innate's facilities and disrupt the operation of Innate's supply chain. 

Concern  over  climate  change  may  also  result  in  new  or  additional  legal  or  regulatory  requirements 
designed  to  reduce  greenhouse  gas  emissions  and/or  mitigate  the  effects  of  climate  change  on  the 
environment. If such laws or regulations are more stringent than current legal or regulatory obligations, 
the  Company  may  experience  disruption  in  or  an  increase  in  the  costs  associated  with  sourcing, 
manufacturing and distribution of Innate's products, which may adversely affect Innate's business, results 
of operations or financial condition.

The current state of the world financial market and current economic conditions could have a material 
adverse impact on the Company's business, financial condition and results of operations.

The global economy is facing a number of actual and potential challenges, including the military conflict 
between Ukraine and Russia, the conflict in Israel and the Middle East region generally, and the banking 
crises or failures, such as the recent failures of Silicon Valley Bank and other U.S. regional banks and the 
instability of certain European banks. If the conditions in the global economy remain uncertain or 
continue to be volatile, or if they deteriorate, including as a result of the ongoing military conflict between 
Russia and Ukraine, the conflict in Israel, banking crises or other geopolitical events, the Company's 
business, financial condition and results of operation may be materially adversely affected.

In  addition,  increases  in  inflation  raise  the  Company's  costs  for  labor,  materials  and  services  and  other 
costs  required  to  grow  and  operate  our  business,  and  failure  to  secure  these  on  reasonable  terms  may 
adversely  impact  its  financial  condition.  Increases  in  inflation,  along  with  the  uncertainties  surrounding 
the  ongoing  COVID-19  pandemic,  geopolitical  developments,  banking  crises  and  global  supply  chain 
disruptions, have caused, and may in the future cause instability and lack of liquidity in capital markets, 
potentially making it more difficult for Innate to obtain additional funds. Such risks and disruptions may 
also negatively impact Innate's supply chain, manufacturing arrangements, preclinical studies and clinical 
trials, which could have a materially adverse impact on its results of operations, financial condition and 
prospects.  The  extent  and  duration  of  the  current  economic  conditions  and  resulting  market  disruptions 
are impossible to predict but could be substantial. Any such disruptions may also magnify the impact of 
other risks described in this Annual Report on Form 20-F.

Risks Related to Intellectual Property Rights 

Its ability to compete may be adversely affected if the Company does not adequately obtain, maintain, 
protect  and  enforce  Innate's  intellectual  property  or  proprietary  rights,  or  if  the  scope  of  intellectual 
property protection the Company obtains is not sufficiently broad. 

Innate's success depends, in large part, on its ability to obtain and maintain patent and other intellectual 
property protection in the United States and other countries with respect to Innate's product candidates. 
However,  the  Company  may  not  be  able  to  obtain,  maintain  or  enforce  Innate's  patents  and  other 
intellectual  property  rights,  which  could  affect  its  ability  to  compete  effectively.  For  example,  the 
Company cannot guarantee: 

•

•

•

•

•

•

that the Company will file all necessary or desirable patent applications or that the Company 
will obtain the patents that the Company has applied for and that are under review; 

that the Company will be able to develop new patentable product candidates or technologies or 
obtain patents to protect such new product candidates or technologies; 

that the Company or its licensing or collaboration partners were the first to make the product 
candidates  or  technologies  covered  by  the  issued  patents  or  pending  patent  applications  that 
the Company licenses or owns; 

that the Company will be able to obtain sufficient rights to all necessary or desirable patents or 
other intellectual property rights, whether at all or on reasonable terms; 

that the scope of any issued patents that the Company owns or licenses will be broad enough 
to  protect  its  product  candidates  or  effectively  prevent  others  from  commercializing 
competitive technologies and product candidates; and 

that  there  is  no  risk  of  its  owned  and  licensed  patents  being  challenged,  invalidated  or 
circumvented by a third party. 

The patent prosecution process is expensive, time-consuming and complex, and Innate may not be able to 
file, prosecute, maintain, enforce or license all necessary or desirable patent applications at a reasonable 
cost or in a timely manner. For example, the Company does not intend to systematically file, maintain, 
prosecute and defend patents on its product candidates in all countries. Consequently, Innate may not be 
able to prevent third parties from exploiting products that are the same as or similar to its products and 
product candidates in countries in which it does not obtain patent protection, or from selling or importing 
such products in and into the countries in which it does have patent protection. It is also possible that the 
Company will fail to identify patentable aspects of its research and development output in time to obtain 
patent  protection.  Although  the  Company  enters  into  confidentiality  agreements  with  parties  who  have 
access to confidential or patentable aspects of its research and development output, such as its employees, 
consultants, CROs, outside scientific collaborators, sponsored researchers and other advisors, any of these 
parties may breach the agreements and disclose such output before a patent application is filed, thereby 
jeopardizing its ability to seek patent protection. Given the amount of time required for the development, 
testing and regulatory review of new product candidates, patents protecting such candidates might expire 
before or shortly after such candidates are commercialized. As a result, Innate's intellectual property may 
not  provide  Innate  with  sufficient  rights  to  exclude  others  from  commercializing  product  candidates 
similar or identical to Innate's products. In addition, in some circumstances, the Company may not have 
the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents 
and  patent  applications  covering  technology  that  the  Company  licenses  to  or  from  third  parties.  For 
example,  pursuant  to  its  license  agreement  with  AstraZeneca  for  monalizumab,  AstraZeneca  retains 

54

control  of  such  activities  for  certain  patents  that  the  Company  licenses  to  it  under  the  agreement  and 
patents  that  arise  under  the  collaboration.  Innate  cannot  be  certain  that  these  patents  and  patent 
applications will be prepared, filed, prosecuted, maintained, enforced and defended in a manner consistent 
with  the  best  interest  of  its  business.  If  any  third  party  that  controls  Innate's  patents  and  patent 
applications fails to maintain Innate's patents or such third party loses rights to Innate's patents or patent 
applications, Innate's rights to those patents and underlying technology may be reduced or eliminated and 
the Company's right to develop and commercialize its product candidates that are subject to such rights 
could be adversely affected. 

Moreover, some of Innate's patents and patent applications are, and may in the future be, co-owned with 
third parties. If the Company is unable to obtain an exclusive license to any such third-party co-owners’ 
interest in such patents or patent applications, such co-owners may be able to license their rights to other 
third  parties,  including  its  competitors,  and  its  competitors  could  market  competing  products  and 
technology. Innate may also need the cooperation of any such co-owners of its patents in order to enforce 
such patents against third parties, and such cooperation may not be provided to us. 

The coverage claimed in a patent application can be significantly reduced before the patent is issued, and 
its  scope  can  be  reinterpreted  after  issuance.  The  issuance  of  a  patent  is  not  conclusive  as  to  its 
inventorship, scope, validity or enforceability. Even if patent applications the Company licenses or owns 
currently or in the future issue as patents, they may not issue in a form that will provide Innate with any 
meaningful  protection,  prevent  competitors  or  other  third  parties  from  circumventing  its  patents  by 
developing  similar  or  alternative  technologies  or  products  in  a  non-infringing  manner,  or  otherwise 
provide Innate with any competitive advantage. Challenges from competitors or other third parties could 
reduce the scope of Innate's patents or render them invalid or unenforceable, which could limit its ability 
to stop others from using or commercializing similar or identical technology and product candidates, or 
limit the duration of the patent protection for Innate Pharma's product candidates. The legal proceedings 
that  the  Company  may  then  have  to  enter  into  in  order  to  enforce  and  defend  its  intellectual  property 
could  be  very  costly  and  could  distract  its  management  and  other  personnel  from  their  normal 
responsibilities,  notably  in  the  case  of  lawsuits  in  the  United  States.  The  probability  of  disputes  arising 
over Innate's intellectual property will increase progressively as patents are granted and as the value and 
appeal of the inventions protected by these patents are confirmed. The occurrence of any of these events 
concerning any of Innate's patents or intellectual property rights could have a material adverse effect on 
its business, prospects, financial condition and results of operations. These risks are even higher for the 
Company, because of its limited financial and human resources. 

The  patent  position  of  biotechnology  and  pharmaceutical  companies  generally  is  highly  uncertain, 
involves complex legal and factual questions, and has been the subject of much litigation in recent years. 
As a result, the issuance, scope, validity, enforceability and commercial value of Innate's patent rights are 
highly uncertain. The Company's pending and future patent applications may not result in patents being 
issued  which  protect  its  technology  or  product  candidates  or  which  effectively  prevent  others  from 
commercializing  competitive  technologies  and  product  candidates.  Furthermore,  its  owned  and  in-
licensed patents may be subject to a reservation of rights by one or more third parties. For example, the 
research resulting in certain of its owned and licensed patent rights and technology was funded in part by 
the  U.S.  government.  As  a  result,  the  government  may  have  certain  rights,  or  march-in  rights,  to  such 
patent  rights  and  technology.  When  new  technologies  are  developed  with  government  funding,  the 
government  generally  obtains  certain  rights  in  any  resulting  patents,  including  a  non-exclusive  license 
authorizing the government to use the invention for non-commercial purposes. These rights may permit 
the  government  to  disclose  Innate's  confidential  information  to  third  parties  and  to  exercise  march-in 
rights to use or allow third parties to use its licensed technology. The government can exercise its march-
in  rights  if  it  determines  that  action  is  necessary  because  the  Company  failed  to  achieve  practical 

55

application of the government-funded technology, because action is necessary to alleviate health or safety 
needs,  to  meet  requirements  of  federal  regulations  or  to  give  preference  to  U.S.  industry.  In  addition, 
Innate's  rights  in  such  inventions  may  be  subject  to  certain  requirements  to  manufacture  products 
embodying  such  inventions  in  the  United  States.  Any  exercise  by  the  government  of  such  rights  could 
harm  Innate  Pharma's  competitive  position,  business,  financial  condition,  results  of  operations  and 
prospects. 

Third parties may allege that the Company or its partners infringe, misappropriate or otherwise violate 
such  third  parties’  intellectual  property  rights,  which  could  prevent  or  delay  its  development  efforts, 
stop Innate from commercializing its product candidates, or increase the costs of commercializing its 
product candidates. 

The  Company's  commercial  success  depends  on  its  ability  and  the  ability  of  its  partners  to  develop, 
manufacture,  market  and  sell  its  product  candidates,  and  use  its  proprietary  technologies,  without 
infringing, misappropriating or otherwise violating any intellectual property or proprietary rights of third 
parties.  The  field  of  biopharmaceuticals  involves  significant  patent  and  other  intellectual  property 
litigation,  which  can  be  highly  uncertain  and  involve  complex  legal  and  factual  questions.  The 
interpretation  and  breadth  of  claims  allowed  in  some  patents  covering  biopharmaceutical  compositions 
also may be uncertain and difficult to determine. 

Innate  may  not  be  aware  of  all  third-party  intellectual  property  rights  potentially  relating  to  its  product 
candidates.  In  general,  in  the  United  States  patent  applications  are  not  published  until  18  months  after 
filing or, in some cases, not at all. Therefore, the Company cannot be sure that it was the first to make the 
inventions claimed in any owned or licensed patents or pending patent applications, or that it was the first 
to file for patent protection for such inventions. If the Company was not the first to invent such inventions 
or first to file any patent or patent application for such inventions, it may be unable to make use of such 
inventions in connection with its products. Innate may need to obtain licenses from third parties (which 
may  not  be  available  under  commercially  reasonable  terms,  or  at  all),  delay  the  launch  of  product 
candidates  or  cease  the  production  and  sale  of  certain  product  candidates  or  develop  alternative 
technologies that are the subject of such patents or patent applications, any of which could have a material 
adverse effect on its business, prospects, financial condition and results of operations. For example, third 
parties  may  claim  that  lacutamab  and  other  product  candidates  may  use  technology  protected  by  their 
patents.  Although  the  Company  believes  that  its  current  activities  and  its  planned  development  of 
lacutamab does not and will not infringe on such patents, which expire in the near term, third parties may 
disagree. 

Third parties may allege that Innate or its partners infringe, misappropriate or otherwise violate any such 
third  party’s  patents  or  other  intellectual  property  rights  and  assert  infringement  claims  against  us, 
regardless of their merit. A court of competent jurisdiction could hold that these third-party patents are 
valid,  enforceable  and  infringed,  which  could  materially  and  adversely  affect  Innate's  ability  to 
commercialize any product candidates it may develop and any other product candidates or technologies 
covered  by  the  asserted  third-party  patents.  In  order  to  successfully  challenge  the  validity  of  any  such 
U.S. patent in federal court, Innate would need to overcome a presumption of validity. As this burden is a 
high one requiring Innate to present clear and convincing evidence as to the invalidity of any such U.S. 
patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of 
any such U.S. patent. If the Company is found to infringe a third party’s intellectual property rights, and 
the Company is unsuccessful in demonstrating that such rights are invalid or unenforceable, the Company 
could be required to: 

•

bear the potentially significant costs of proceedings brought against us; 

56

•

•

•

pay damages, which may include treble damages and attorney’s fees if the Company is found 
to have willfully infringed a third party’s patent rights; 

cease  developing,  manufacturing  and  commercializing  the  infringing  technology  or  product 
candidates; and 

acquire a license to such third-party intellectual property rights, which may not be available on 
commercially  reasonable  terms,  or  at  all,  and  may  be  non-exclusive,  thereby  giving  the 
Company's competitors and other third parties access to the same technologies licensed to us. 

Even if resolved in Innate's favor, litigation or other intellectual property proceedings may cause Innate to 
incur  significant  expenses  and  could  distract  its  management  and  other  personnel  from  their  normal 
responsibilities. In addition, there could be public announcements of the results of hearings, motions or 
other interim proceedings or developments, and if securities analysts or investors perceive these results to 
be negative, it could have a material adverse effect on the price of Innate's ordinary shares or ADSs. The 
Company  may  not  have  sufficient  financial  or  other  resources  to  adequately  conduct  such  litigation  or 
proceedings.  Some  of  Innate's  competitors  may  be  able  to  sustain  the  costs  of  such  litigation  or 
proceedings more effectively than Innate can because of their greater financial resources and more mature 
and developed intellectual property portfolios. Should one or more of the foregoing risks materialize, this 
could  have  a  material  adverse  effect  on  Innate's  reputation,  business,  prospects,  financial  condition  and 
results of operations. 

Its patents could be found invalid or unenforceable if challenged, and the Company may not be able to 
protect its intellectual property. 

Innate's  and  its  licensors’  patents  and  patent  applications,  if  issued,  may  be  challenged,  invalidated  or 
circumvented  by  third  parties.  U.S.  patents  and  patent  applications  may  also  be  subject  to  interference 
proceedings, re-examination proceedings, derivation proceedings, post-grant review or inter partes review 
in the United States Patent and Trademark Office (USPTO), challenging Innate's or its licensors’ patent 
rights. Foreign patents may be subject also to opposition or comparable proceedings in the corresponding 
foreign patent office. For example, a third party filed an opposition in the European Patent Office (EPO) 
challenging  one  of  the  Company's  European  patents  with  claims  directed  to  use  of  anti-NKG2A 
antibodies  for  treating  cancer  in  an  individual  having  progressive  disease  following  treatment  with  an 
antibody  that  neutralizes  the  inhibitory  activity  of  PD-1.  The  EPO  issued  a  decision  maintaining  the 
Company's patent as granted, however the third party has appealed such decision. Third-party oppositions 
have  also  been  filed  challenging  two  of  the  Company's  in-licensed  European  patents  directed  to  CD39 
technology. One of these oppositions has not yet resulted in a first-instance decision in the EPO, while the 
other opposition resulted in the revocation of the patents directed to CD39 technology, which revocation 
was appealed by Innate's licensor(s). All of the aforementioned oppositions are currently pending. 

In addition, the Company may allege that third parties infringe Innate's or its licensors’ patents, and the 
defendant  could  counterclaim  that  such  patents  are  invalid  or  unenforceable.  In  patent  litigation  in  the 
United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds 
for  a  validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements, 
including  lack  of  novelty,  obviousness  or  non-enablement.  Grounds  for  an  unenforceability  assertion 
could  be  an  allegation  that  someone  connected  with  prosecution  of  the  patent  withheld  relevant 
information  from  the  USPTO,  or  made  a  misleading  statement,  during  prosecution.  The  outcome 
following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity 
question, for example, Innate Pharma cannot be certain that there is no invalidating prior art of which the 
Company or its licensing partners and the patent examiner were unaware during prosecution. 

Any such patent litigation or proceeding could result in the loss of Innate or its licensors’ patents, denial 
of  Innate's  or  its  licensors’  patent  applications  or  loss  or  reduction  in  the  scope  of  one  or  more  of  the 

57

claims  of  such  patents  or  patent  applications.  Accordingly,  Innate's  or  its  licensors’  rights  under  any 
issued patents may not provide Innate with sufficient protection against competitive product candidates or 
processes; Innate could become unable to manufacture or commercialize its product candidates without 
infringing  third-party  patent  rights;  and  the  duration  of  the  patent  protection  of  its  product  candidates 
could be limited. Furthermore, because of the substantial amount of discovery required in connection with 
intellectual  property  litigation,  there  is  a  risk  that  some  of  Innate's  confidential  information  could  be 
compromised  by  disclosure  during  this  type  of  litigation.  Even  if  the  Company  is  successful,  such 
litigation or proceedings may be costly and may distract its management and other personnel from their 
normal responsibilities. Any of the foregoing could have a material adverse effect on Innate's business, 
prospects, financial condition and results of operations. 

Obtaining  and  maintaining  the  Company's  patent  protection  depends  on  compliance  with  various 
procedural, document submission, fee payment and other requirements imposed by government patent 
agencies,  and  its  patent  protection  could  be  reduced  or  eliminated  for  non-compliance  with  these 
requirements. 

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/
or applications will be due to be paid to the USPTO, and various government patent agencies outside of 
the United States over the lifetime of Innate's owned and licensed patents and/or patent applications and 
any patent rights the Company may own in the future. In certain circumstances, Innate Pharma may rely 
on  its  licensing  partners  to  pay  these  fees.  The  USPTO  and  various  foreign  patent  agencies  require 
compliance  with  several  procedural,  documentary,  fee  payment  and  other  similar  provisions  during  the 
patent application process. In many cases, an inadvertent lapse can be cured by payment of a late fee or 
by  other  means  in  accordance  with  the  applicable  rules.  There  are  situations,  however,  in  which  non-
compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or 
complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be 
able  to  enter  the  market  with  similar  or  identical  products  or  technology,  which  could  have  a  material 
adverse effect on Innate's business, prospects, financial condition and results of operations. 

Developments in patent law could have a negative impact on the Company's business. 

Changes in either the patent laws or interpretation of the patent laws could increase the uncertainties and 
costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. 
For example, from time to time, the U.S. Congress, the USPTO or similar foreign authorities may change 
the standards of patentability, and any such changes could have a negative impact on Innate's business. 
One example is the Leahy-Smith America Invents Act, or the America Invents Act, which was signed into 
law in September 2011, and includes a number of significant changes to U.S. patent law. These changes 
included a transition from a “first-to-invent” system to a “first-to-file” system, changes to the way issued 
patents  are  challenged  and  changes  to  the  way  patent  applications  are  disputed  during  the  examination 
process  such  as  allowing  third-party  submission  of  prior  art  to  the  USPTO  during  patent  prosecution. 
Changes in patent laws may also modify the jurisdictions relevant to patents. For example, in Europe, the 
unitary patent (UP), or "European patent with unitary effect", established under Regulation 1257/2012 of 
December 17, 2012, provides a single supra-national patent right covering up to 25 EU Member States as 
from June 1, 2023. 

Trademarks 

In addition, changes to or different interpretations of patent laws in the United States and other countries 
may  permit  others  to  use  Innate's  or  its  partners’  discoveries  or  to  develop  and  commercialize  Innate's 
technology  and  product  candidates  without  providing  any  compensation  to  Innate,  or  may  limit  the 
number  of  patents  or  claims  it  can  obtain.  The  patent  positions  of  companies  in  the  biotechnology  and 
pharmaceutical market are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the 

58

scope  of  U.S.  patent  protection  available  in  certain  circumstances  and  weakened  the  rights  of  patent 
owners  in  certain  situations.  This  combination  of  events  has  created  uncertainty  with  respect  to  the 
validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, 
the federal courts, and the USPTO, as well as similar bodies in other countries, the laws and regulations 
governing  patents  could  change  in  unpredictable  ways  that  could  have  a  material  adverse  effect  on 
Innate's existing patent portfolio and its ability to protect and enforce its intellectual property in the future, 
which could have a material adverse effect on its business, prospects, financial condition and results of 
operations. 

If the  Company does not obtain protection under the Hatch-Waxman Amendments and similar non-
U.S. legislation for extending the term of patents covering each of its product candidates, its business 
may be materially harmed. 

Depending upon the timing, duration and conditions of FDA marketing authorization of Innate's product 
candidates,  one  or  more  of  its  U.S.  patents  may  be  eligible  for  limited  patent  term  extension  under  the 
Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Amendments, 
and  similar  legislation  in  the  European  Union.  The  Hatch-Waxman  Amendments  permit  a  patent  term 
extension  of  up  to  five  years  for  a  patent  covering  an  approved  product  as  compensation  for  effective 
patent  term  lost  during  product  development  and  the  FDA  regulatory  review  process.  A  patent  term 
extension  cannot  extend  the  remaining  term  of  a  patent  beyond  a  total  of  14  years  from  the  date  of 
product approval, only one patent may be extended, and only those claims covering the approved product, 
a method for using it or a method for manufacturing it may be extended. However, the Company may not 
receive  an  extension  if  the  Company  fails  to  apply  within  applicable  deadlines,  fails  to  apply  prior  to 
expiration of relevant patents, fails to exercise due diligence during the testing Phase or regulatory review 
process or otherwise fails to satisfy applicable requirements. Moreover, the length of the extension could 
be less than what the Company requests. If the Company is unable to obtain patent term extension or the 
term of any such extension is less than its requests, the period during which the Company can enforce its 
patent  rights  for  that  product  will  be  shortened,  and  its  competitors  may  obtain  approval  to  market 
competing  products  sooner.  As  a  result,  Innate's  revenue  from  an  applicable  product  could  be  reduced, 
possibly  materially,  which  could  have  a  material  adverse  effect  on  its  business,  prospects,  financial 
condition and results of operations. 

The Company will not seek to protect its intellectual property rights in all jurisdictions throughout the 
world,  and  Innate  may  not  be  able  to  adequately  enforce  its  intellectual  property  rights  in  all 
jurisdictions where Innate Pharma seeks intellectual property protection. 

Filing, maintaining, prosecuting and defending patents on Innate's product candidates in all countries and 
jurisdictions throughout the world would be prohibitively expensive, and its intellectual property rights in 
some  countries  outside  the  United  States  could  be  less  extensive  than  those  in  the  United  States. 
Consequently, the Company may not be able to prevent third parties from using its product candidates or 
technologies in all countries outside the United States, or from selling or importing products made using 
its  product  candidates  or  technologies  in  and  into  the  United  States  or  other  jurisdictions.  Competitors 
may  use  Innate's  technologies  in  jurisdictions  where  Innate  Pharma  does  not  pursue  and  obtain  patent 
protection  to  develop  their  own  products  and,  further,  may  export  otherwise  infringing  products  to 
territories where the Company has patent protection, and enforcement is not as strong as that in the United 
States. These products may compete with Innate's products, and its patents or other intellectual property 
rights may not be effective or sufficient to prevent them from competing. Even if the Company pursues 
and obtains issued patents in particular jurisdictions, its patent claims or other intellectual property rights 
may not be effective or sufficient to prevent third parties from so competing. 

In  addition,  the  laws  of  some  foreign  countries  do  not  protect  intellectual  property  rights  to  the  same 
extent as the federal and state laws in the United States. Many companies have encountered significant 

59

problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal 
systems of some countries, particularly developing countries, do not favor the enforcement of patents and 
other intellectual property protection, especially those relating to biopharmaceuticals or biotechnologies. 
This could make it difficult for Innate Pharma to stop the infringement of its patents, if obtained, or the 
misappropriation  or  other  violation  of  its  other  intellectual  property  rights.  For  example,  many  foreign 
countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. 
In addition, many countries limit the enforceability of patents against third parties, including government 
agencies or government contractors. In these countries, patents may provide limited or no benefit. Patent 
protection  must  ultimately  be  sought  on  a  country-by-country  basis,  which  is  an  expensive  and  time-
consuming process with uncertain outcomes. Accordingly, the Company may choose not to seek patent 
protection  in  certain  countries,  and  the  Company  will  not  have  the  benefit  of  patent  protection  in  such 
countries. 

Proceedings to enforce Innate's patent rights in foreign jurisdictions could result in substantial costs and 
divert  its  efforts  and  attention  from  other  aspects  of  its  business,  could  put  its  patents  at  risk  of  being 
invalidated  or  interpreted  narrowly,  could  put  its  patent  applications  at  risk  of  not  issuing  and  could 
provoke third parties to assert claims against us. The Company may not prevail in any lawsuits that the 
Company  initiates,  and  the  damages  or  other  remedies  awarded,  if  any,  may  not  be  commercially 
meaningful. In addition, changes in the law and legal decisions by courts in the United States and other 
countries may affect Innate's ability to obtain adequate protection for its technology and the enforcement 
of its intellectual property. Accordingly, Innate's efforts to enforce its intellectual property rights around 
the world may be inadequate to obtain a significant commercial advantage from the intellectual property 
that the Company develops or licenses. Should any of these risks materialize, this could have a material 
adverse effect on Innate's business, prospects, financial condition and results of operations. 

Third  parties  may  assert  ownership  or  commercial  rights  to  products,  product  candidates  or 
technologies that Innate develops. 

Third parties have made, and may in the future make, claims challenging the inventorship or ownership of 
Innate's intellectual property, which may result in the imposition of additional obligations on us, such as 
development, royalty and milestone payments. Innate has written agreements with partners or other third 
parties that provide for the ownership of intellectual property arising from its collaborations and its other 
work  with  such  third  parties.  These  agreements  provide  that  the  Company  must  negotiate  certain 
commercial rights with partners and other third parties with respect to joint inventions or inventions made 
by its partners or such third parties that arise from the results of the collaboration or other work with such 
third  parties.  In  some  instances,  there  may  not  be  adequate  written  provisions  to  address  clearly  the 
resolution of intellectual property rights that may arise under Innate's agreements. If the Company cannot 
successfully negotiate sufficient ownership and commercial rights to the inventions that result from its use 
of a third party’s materials where required, or if disputes otherwise arise with respect to the intellectual 
property developed with the use of a third party’s samples, the Company may be limited in its ability to 
capitalize on the market potential of these inventions. In addition, the Company may face claims by third 
parties  that  its  agreements  with  employees,  contractors  or  consultants  obligating  them  to  assign 
intellectual property to itself are ineffective, or in conflict with prior or competing contractual obligations 
of assignment, which could result in ownership disputes regarding intellectual property the Company has 
developed  or  will  develop  and  interfere  with  its  ability  to  capture  the  commercial  value  of  such 
inventions. The Company also may be unsuccessful in executing assignment agreements with each party 
who,  in  fact,  conceives  or  develops  intellectual  property  that  the  Company  regards  as  its  own,  or  such 
agreements might not be self-executing or might be breached. 

Litigation may be necessary to resolve an ownership dispute, and if the Company is not successful, Innate 
may  be  precluded  from  using  certain  intellectual  property,  may  lose  its  exclusive  rights  in  such 

60

intellectual property or may be required to acquire a license to such intellectual property, which may not 
be  available  on  commercially  reasonable  terms  or  at  all.  Any  of  the  foregoing  could  have  a  material 
adverse impact on Innate's business. 

If the Company fails to comply with its obligations under license or technology agreements with third 
parties, Innate Pharma could lose license rights that are critical to its business, and the Company may 
not be successful in obtaining necessary intellectual property rights. 

Innate  licenses  intellectual  property  from  third  parties  that  is  critical  to  its  business  through  license 
agreements, including but not limited to licenses related to the manufacture, composition, use and sale of 
its product candidates, and in the future Innate may enter into additional agreements that provide it with 
licenses  to  valuable  intellectual  property  or  technology.  For  example,  Innate  depends  on  its  license 
agreement with Novo Nordisk A/S for the development and commercialization of monalizumab. Innate's 
license  agreements  impose  various  obligations  on  us,  which  may  include  development,  royalty  and 
milestone payments. If the Company fails to comply with any of these obligations, its licensors may have 
the right to terminate the agreements. If its license agreements with AstraZeneca or Novo Nordisk A/S or 
any  other  current  or  future  licensors  terminate,  the  Company  would  lose  valuable  rights  and  may  be 
required to cease its development, manufacture or commercialization of its product candidates, including 
monalizumab.  In  addition,  its  business  would  suffer  if  its  licensors  fail  to  abide  by  the  terms  of  the 
agreements, if its licensors fail to prevent infringement by third parties or if the licensed patents or other 
rights are found to be invalid or unenforceable. Should any of these risks materialize, this could have a 
material adverse effect on Innate's business, prospects, financial condition and results of operations. 

In addition, disputes may arise regarding intellectual property subject to a license agreement, including: 

•

•

•

•

•

the scope of rights granted under the license agreement and other interpretation-related issues; 

the  extent  to  which  its  technology  and  processes  infringe  on  intellectual  property  of  the 
counterparty that is not subject to the license agreement; 

Innate's  diligence  obligations  under  the  license  agreement  and  what  activities  satisfy  those 
diligence obligations; 

the inventorship or ownership of inventions and know-how resulting from the joint creation or 
use of intellectual property by its counterparties and us; and 

the priority of invention of patented technology. 

The agreements under which the Company currently licenses intellectual property from third parties are 
complex,  and  certain  provisions  in  such  agreements  may  be  susceptible  to  multiple  interpretations.  The 
resolution of any contract dispute that may arise could narrow what Innate believes to be the scope of its 
rights  to  the  relevant  intellectual  property,  or  modify  in  a  manner  adverse  to  Innate  what  the  Company 
believes to be Innate's or its counterpart’s financial or other obligations under the relevant agreement, any 
of  which  could  have  a  material  adverse  effect  on  its  business,  financial  condition,  results  of  operations 
and prospects. If disputes over intellectual property that Innate Pharma has licensed prevent or impair its 
ability  to  maintain  its  current  license  agreement  on  acceptable  terms,  the  Company  may  be  unable  to 
unsuccessfully develop and commercialize the affected product candidates. 

Additionally, the growth of Innate's business may depend, in part, on its ability to acquire, in-license or 
use  proprietary  rights  held  by  third  parties.  The  Company  may  be  unable  to  acquire  or  in-license 
intellectual property rights from third parties that Innate identifies as necessary for its product candidates 
on reasonable terms or at all. The licensing or acquisition of third-party intellectual property rights is a 
competitive  area,  and  several  more  established  companies  may  pursue  strategies  to  license  or  acquire 
third-party  intellectual  property  rights  that  the  Company  may  consider  attractive.  These  established 

61

companies may have a competitive advantage over Innate due to their size, capital resources and greater 
clinical development and commercialization capabilities. In addition, companies that perceive Innate to be 
a competitor may be unwilling to assign or license rights to us. Innate also may be unable to license or 
acquire third-party intellectual property rights on terms that would allow Innate to make an appropriate 
return on its investment. 

As part of its business, the Company collaborates with non-profit and academic institutions to accelerate 
its  preclinical  research  or  development  under  agreements  with  these  institutions.  Typically,  these 
institutions  provide  Innate  with  an  option  to  negotiate  a  license  to  any  of  the  institution’s  or  its 
employees’ rights in technology resulting from the collaboration. Regardless of such option, Innate may 
be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If 
the Company is unable to do so, the institution may offer the intellectual property rights to other parties, 
potentially  blocking  its  ability  to  pursue  its  applicable  development  or  commercialization  program.  If 
Innate Pharma is unable to successfully obtain rights to required third-party intellectual property rights or 
maintain  the  existing  intellectual  property  rights  Innate  Pharma  has,  Innate  may  have  to  abandon  the 
development and commercialization of the relevant program, and its business, financial conditions, results 
of operations and prospects could be adversely affected. 

Third  parties  may  assert  that  Innate's  employees,  consultants  or  independent  contractors  have 
wrongfully used or disclosed confidential information or misappropriated trade secrets of their current 
or former employers. 

The  Company  employs  individuals  who  are  currently,  or  were  previously,  employed  at  universities  or 
other  biotechnology  or  pharmaceutical  companies,  including  its  competitors  or  potential  competitors. 
Although Innate tries to ensure that its employees, consultants and independent contractors do not use the 
proprietary information or know-how of others in their work for Innate, and no such claims against it are 
currently  pending,  Innate  may  be  subject  to  claims  that  Innate  or  its  employees,  consultants  or 
independent  contractors  have  used  or  disclosed  intellectual  property,  including  trade  secrets  or  other 
proprietary  information,  of  any  such  individual’s  current  or  former  employer  or  other  third  parties. 
Litigation may be necessary to defend against these claims. If Innate fails in defending any such claims, 
in  addition  to  paying  monetary  damages,  Innate  may  lose  valuable  intellectual  property  rights  or 
personnel.  Even  if  Innate  is  successful  in  defending  against  such  claims,  litigation  could  result  in 
substantial costs and be a distraction to its management and other employees. Should any of these risks 
materialize, this could have a material adverse effect on Innate's business, prospects, financial condition 
and results of operations. 

If the Company is unable to protect the confidentiality of its trade secrets, its business and competitive 
position could be materially harmed. 

In  addition  to  patent  protection,  because  the  Company  operates  in  the  highly  technical  field  of 
biopharmaceutical  drug  development,  it  relies  in  part  on  trade  secret  protection  in  order  to  protect  its 
proprietary technology and processes. However, trade secrets are difficult to protect. The Company seeks 
to  protect  its  trade  secrets,  in  part,  by  entering  into  confidentiality  agreements  with  its  employees, 
consultants,  CROs,  outside  scientific  collaborators,  sponsored  researchers  and  other  advisors.  These 
agreements  generally  require  that  the  other  party  keep  confidential  and  not  disclose  to  third  parties  all 
confidential  information  developed  by  such  party  or  made  known  to  such  party  by  Innate  during  the 
course of such party’s relationship with us. However, Innate cannot guarantee that it has entered into such 
agreements  with  each  party  that  may  have  or  have  had  access  to  its  trade  secrets  and  confidential 
information, and these agreements may be breached, and Innate may not have adequate remedies for any 
breach. 

62

In addition to contractual measures, the Company tries to protect the confidential nature of its proprietary 
information using physical and technological security measures. Such measures may not, for example, in 
the  case  of  misappropriation  of  a  trade  secret  by  an  employee  or  third  party  with  authorized  access, 
provide  adequate  protection  for  Innate's  proprietary  information.  Innate's  security  measures  may  not 
prevent  an  employee  or  consultant  from  misappropriating  its  trade  secrets  and  providing  them  to  a 
competitor, and recourse it takes against such misconduct may not provide an adequate remedy to protect 
its interests fully. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can 
be difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside 
the  United  States  may  be  less  willing  to  protect  trade  secrets.  Moreover,  trade  secrets  may  be 
independently  developed  by  others  in  a  manner  that  could  prevent  legal  recourse  by  Innate.  If  any  of 
Innate's  confidential  or  proprietary  information,  such  as  its  trade  secrets,  were  to  be  disclosed  to  or 
misappropriated by a third party, or if any such information was independently developed by a third party, 
its competitive position could be materially harmed. 

Innate's trade and technical secrets include: 

•

•

•

•

certain  unpatented  technical  expertise  that  the  Company  believes  provides  itself  with  an 
advantage in conducting research and development work in its field; 

certain scientific knowledge generated by the work the Company carries out; 

certain  information  relating  to  the  product  candidates  the  Company  is  currently  developing; 
and 

certain information relating to the agreements signed between the Company and third parties. 

The  unauthorized  disclosure  or  misappropriation  of  certain  of  these  secrets  could  allow  third  parties  to 
offer  products  or  services  to  compete  with  its  or  generally  have  a  material  adverse  effect  on  Innate's 
business. 

The structures put in place to protect Innate's trade and technical secrets do not constitute a guarantee that 
one or more of its trade and technical secrets will not be disclosed or misappropriated. The agreements or 
other arrangements to  protect the Company's trade secrets may fail to provide the protection sought,  or 
may be breached, or its trade secrets may be disclosed to, or developed independently by, its competitors. 
Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's  business, 
prospects, financial condition and results of operations. 

Unauthorized use of Innate's trademarks may generate confusion and result in costs and delays to the 
detriment of its marketing efforts. 

Innate's trademarks are a key component of its identity and its products. Although the key components of 
its  trademarks  have  been  registered,  notably  in  France  and  the  United  States,  other  companies  in  the 
pharmaceutical  sector  might  use  or  attempt  to  use  similar  trademarks  or  components  of  the  Company's 
trademarks  and  thereby  create  confusion  in  the  minds  of  third  parties.  Innate  Pharma's  registered 
trademarks may be challenged, infringed, circumvented or declared generic or determined to be infringing 
on other marks. In addition, there could be potential trademark infringement claims brought by owners of 
other trademarks that incorporate variations of Innate's registered or unregistered trademarks. 

In the event the Company develops trademarks for products that conflict with intellectual property rights 
of third parties, Innate would then have to redesign or rename its products in order to avoid encroaching 
on the intellectual property rights of third parties. This could prove to be impossible or costly in terms of 
time and financial resources and could be detrimental to Innate's marketing efforts. Should any of these 
risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial 
condition and results of operations. 

63

Intellectual property rights do not necessarily address all potential threats. 

The  degree  of  future  protection  afforded  by  the  Company's  intellectual  property  rights  is  uncertain 
because intellectual property rights have limitations and may not adequately protect its business or permit 
it to maintain its competitive advantage. For example: 

•

•

•

•

•

•

•

•

•

•

others may be able to make products that are the same as or similar to its product candidates or 
utilize  similar  technology  but  that  are  not  covered  by  the  claims  of  the  patents  that  the 
Company licenses or may own in the future; 

the Company, or its license partners or current or future collaborators, might not have been the 
first to make the inventions covered by the issued patent or pending patent application that the 
Company licenses or may own in the future; 

the Company, or its license partners or current or future collaborators, might not have been the 
first to file patent applications covering certain of its or their inventions; 

others may independently develop similar or alternative technologies or duplicate any of the 
Company's technologies without infringing its owned or licensed intellectual property rights; 

it is possible that the Company's owned or licensed pending patent applications will not lead to 
issued patents; 

issued  patents  that  the  Company  holds  rights  to  may  be  held  invalid  or  unenforceable, 
including as a result of legal challenges by its competitors; 

its  competitors  might  conduct  research  and  development  activities  in  countries  where  the 
Company does not have patent rights and then use the information learned from such activities 
to develop competitive products for sale in its major commercial markets; 

the Company may not develop additional proprietary technologies that are patentable; 

the patents of others may harm the Company's business; and 

the  Company  may  choose  not  to  file  a  patent  in  order  to  maintain  certain  trade  secrets  or 
know-how,  and  a  third  party  may  subsequently  file  a  patent  covering  such  intellectual 
property. 

Should any of these events occur, they could have a material adverse effect on Innate's business, financial 
condition, results of operations and prospects. 

Risks Related to Ownership of the Company's Ordinary Shares and the ADSs

The trading price of Innate's equity securities may be volatile, and purchasers of its ordinary shares or 
ADSs could incur substantial losses. 

It  is  likely  that  the  price  of  the  Company's  ordinary  shares  and  ADSs  will  be  significantly  affected  by 
events  such  as  announcements  regarding  scientific  and  clinical  results  concerning  product  candidates 
currently  being  developed  by  us,  its  collaboration  partners  or  its  main  competitors,  changes  in  market 
conditions related to its sector of activity, announcements of new contracts, technological innovations and 
collaborations by Innate or its main competitors, developments concerning intellectual property rights, as 
well  as  the  development,  regulatory  approval  and  commercialization  of  new  products  by  Innate  or  its 
main competitors and changes in its financial results. 

Equity markets are subject to considerable price fluctuations, and often these movements do not reflect 
the operational and financial performance of the listed companies concerned. In particular, biotechnology 

64

companies’ share prices have been highly volatile and may continue to be highly volatile in the future. As 
the Company operates  in a  single industry, Innate is especially vulnerable to these factors to the  extent 
that they affect its industry. Fluctuations in the stock market as well as the macro-economic environment 
could significantly affect the price of its ordinary shares. As a result of this volatility, investors may not 
be  able  to  sell  their  ordinary  shares  or  ADSs  at  or  above  the  price  originally  paid  for  the  security.  The 
market  price  for  Innate  Pharma's  ordinary  shares  and  ADSs  may  be  influenced  by  many  factors, 
including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated fluctuations in its financial condition and operating results; 

actual or anticipated changes in its growth rate relative to its competitors; 

competition from existing products or new products that may emerge; 

announcements by Innate or its competitors of significant acquisitions, strategic partnerships, 
joint ventures, collaborations or capital commitments; 

adverse  results  of  delays  in  Innate's  or  any  of  its  competitors’  preclinical  studies  or  clinical 
trials; 

adverse  regulatory  decisions,  including  failure  to  receive  regulatory  approval  for  any  of  its 
product candidates; 

the termination of a strategic alliance or the inability to establish additional strategic alliances; 

failure to meet or exceed financial estimates and projections of the investment community or 
that the Company provides to the public; 

issuance of new or updated research or reports by securities analysts; 

fluctuations in the valuation of companies perceived by investors to be comparable to us; 

ordinary share and American Deposit Share (ADS) price and volume fluctuations attributable 
to inconsistent trading volume levels of its ordinary shares and ADSs; 

price and volume fluctuations in trading of its ordinary shares on Euronext Paris; 

additions or departures of key management or scientific personnel; 

disputes  or  other  developments  related  to  proprietary  rights,  including  patents,  litigation 
matters  and  its  ability  to  obtain  patent  and  other  intellectual  property  protection  for  its 
technologies; 

changes  to  coverage  policies  or  reimbursement  levels  by  commercial  third-party  payors  and 
government  payors  and  any  announcements  relating  to  coverage  policies  or  reimbursement 
levels; 

announcement or expectation of additional debt or equity financing efforts; 

sales of its ordinary shares or ADSs by Innate, its insiders or its other shareholders; and 

general economic and market conditions.

These and other market and industry factors may cause the market price and demand for Innate's ordinary 
shares  and  ADSs  to  fluctuate  substantially,  regardless  of  its  actual  operating  performance,  which  may 
limit  or  prevent  investors  from  readily  selling  their  ordinary  shares  or  ADSs  and  may  otherwise 
negatively affect the liquidity of the trading market for the ordinary shares and ADSs. 

65

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research 
about  Innate's  business,  the  price  of  the  ordinary  shares  or  ADSs  and  their  trading  volume  could 
decline. 

The  trading  market  for  the  ADSs  and  ordinary  shares  depends  in  part  on  the  research  and  reports  that 
securities or industry analysts publish about Innate or its business. As a public company in France since 
2006, the Company's equity securities are currently subject to coverage by a number of analysts. If fewer 
securities  or  industry  analysts  cover  its  company,  the  trading  price  for  the  ADSs  and  ordinary  shares 
would  be  negatively  impacted.  If  one  or  more  of  the  analysts  who  covers  Innate  downgrades  Innate's 
equity  securities  or  publishes  incorrect  or  unfavorable  research  about  Innate's  business,  the  price  of  the 
ordinary shares and ADSs would likely decline. If one or more of these analysts ceases coverage of the 
Company or fails to publish reports on Innate regularly, or downgrades Innate's securities, demand for the 
ordinary shares and ADSs could decrease, which could cause the price of the ordinary shares and ADSs 
or their trading volume to decline. 

The  Company  does  not  currently  intend  to  pay  dividends  on  its  securities  and,  consequently,  your 
ability to achieve a return on your investment will depend on appreciation in the price of the ordinary 
shares and ADSs. In addition, French law may limit the amount of dividends the Company is able to 
distribute. 

Innate has never declared or paid any cash dividends on its ordinary shares and does not currently intend 
to do so for the foreseeable future. The Company currently intends to invest its future earnings, if any, to 
fund its growth. Therefore, the holders of Innate's ordinary shares and ADSs are not likely to receive any 
dividends  for  the  foreseeable  future,  and  the  success  of  an  investment  in  its  ordinary  shares  and  ADSs 
depends  upon  any  future  appreciation  in  value.  Consequently,  investors  may  need  to  sell  all  or  part  of 
their holdings of the ordinary shares or ADSs after price appreciation, which may never occur, as the only 
way  to  realize  any  future  gains  on  their  investment.  There  is  no  guarantee  that  the  ordinary  shares  or 
ADSs will appreciate in value or even maintain the price at which Innate's shareholders have purchased 
them. 

Further, under French law, the determination of whether the Company has been sufficiently profitable to 
pay  dividends  is  made  on  the  basis  of  its  statutory  financial  statements  prepared  and  presented  in 
accordance  with  accounting  standards  applicable  in  France.  Moreover,  pursuant  to  French  law,  the 
Company must allocate 5% of its unconsolidated net profit for each year to its legal reserve fund before 
dividends, should the Company propose to declare any, may be paid for that year, until the amount in the 
legal reserve is equal to 10% of the aggregate nominal value of its issued and outstanding share capital. In 
addition, payment of dividends may subject Innate to additional taxes under French law. Therefore, Innate 
may  be  more  restricted  in  its  ability  to  declare  dividends  than  companies  that  are  not  incorporated  in 
France. 

In  addition,  exchange  rate  fluctuations  may  affect  the  amount  of  euros  that  the  Company  is  able  to 
distribute, and the amount in U.S. dollars that its shareholders receive upon the payment of cash dividends 
or other distributions the Company declares and pays in euro, if any. These factors could harm the value 
of the ADSs, and, in turn, the U.S. dollar proceeds that holders receive from the sale of the ADSs. 

Future sales, or the possibility of future sales, of a substantial number of Innate's ADSs or ordinary 
shares could adversely affect the market price of its ADSs and ordinary shares. 

Future sales of a substantial number of Innate's ADSs or ordinary shares, or the perception that such sales 
will  occur,  could  cause  a  decline  in  the  market  price  of  its  ADSs  and/or  ordinary  shares.  Sales  in  the 
United States of Innate ADSs and ordinary shares held by its directors, officers and affiliated shareholders 
or ADS holders are subject to restrictions. If these shareholders or ADS holders sell substantial amounts 
of ordinary shares or ADSs in the public market, or the market perceives that such sales may occur, the 

66

market price of Innate's ADSs or ordinary shares and its ability to raise capital through an issue of equity 
securities in the future could be adversely affected. 

The dual listing of Innate's ordinary shares and the ADSs may adversely affect the liquidity and value 
of the ADSs. 

Innate's ADSs are listed on the Nasdaq, and its ordinary shares are admitted to trading on Euronext Paris. 
Trading of the ADSs or ordinary shares in these markets take place in different currencies (U.S. dollars on 
the  Nasdaq  and  euro  on  Euronext  Paris),  and  at  different  times  (resulting  from  different  time  zones, 
different trading days and different public holidays in the United States and France). The trading prices of 
the  Company's  ordinary  shares  on  these  two  markets  may  differ  due  to  these  and  other  factors.  Any 
decrease in the price of Innate's ordinary shares on Euronext Paris could cause a decrease in the trading 
price  of  the  ADSs  on  Nasdaq.  Investors  could  seek  to  sell  or  buy  Innate's  ordinary  shares  to  take 
advantage of any price differences between the markets through a practice referred to as arbitrage. Any 
arbitrage  activity  could  create  unexpected  volatility  in  both  its  share  prices  on  one  exchange,  and  the 
ordinary  shares  available  for  trading  on  the  other  exchange.  In  addition,  holders  of  ADSs  are  not 
immediately able to surrender their ADSs and withdraw the underlying ordinary shares for trading on the 
other market without effecting necessary procedures with the depositary. This could result in time delays 
and additional cost for holders of ADSs. The Company cannot predict the effect of this dual listing on the 
value of its ordinary shares and the ADSs. However, the dual listing of its ordinary shares and the ADSs 
may  reduce  the  liquidity  of  these  securities  in  one  or  both  markets  and  may  adversely  affect  the 
development of an active trading market for the ADSs in the United States. 

The rights of shareholders in companies subject to French corporate law differ in material respects 
from the rights of shareholders of corporations incorporated in the United States. 

The Company is a French company with limited liability. Its corporate affairs are governed by its bylaws 
and  by  the  laws  governing  companies  incorporated  in  France.  The  rights  of  shareholders  and  the 
responsibilities of members of Innate's Executive Board and of its Supervisory Board are in many ways 
different  from  the  rights  and  obligations  of  shareholders  in  companies  governed  by  the  laws  of  U.S. 
jurisdictions.  For  example,  in  the  performance  of  its  duties,  Innate's  Executive  Board  is  required  by 
French  law  to  consider  the  interests  of  Innate,  its  shareholders,  its  employees  and  other  stakeholders, 
rather  than  solely  Innate's  shareholders  and/or  creditors.  It  is  possible  that  some  of  these  parties  have 
interests that are different from, or in addition to, your interests as a shareholder or holder of ADSs. See 
“Item 16G.—Corporate Governance.” 

U.S. investors may have difficulty enforcing civil liabilities against the Company and members of the 
Executive Board and the Supervisory Board. 

Most of the members of Innate's Executive Board and Supervisory Board and the experts named therein 
are non-residents of the United States, and all or a substantial portion of its assets and the assets of such 
persons are located outside the United States. As a result, it may not be possible to serve process on such 
persons  or  Innate  in  the  United  States  or  to  enforce  judgments  obtained  in  U.S.  courts  against  them  or 
Innate based on civil liability provisions of the securities laws of the United States. Additionally, it may 
be difficult to obtain jurisdiction over us or our non-U.S. resident members of the Executive Board and 
Supervisory Board in U.S. courts in actions predicated on the civil liability provisions of the U.S. federal 
securities  law,  or  assert  U.S.  securities  law  claims  in  actions  originally  instituted  outside  of  the  United 
States. Foreign courts may refuse to hear a U.S. securities law claim because foreign courts may not be 
the most appropriate forums in which to bring such a claim. Even if a foreign court agrees to hear a claim, 
it may determine that the law of the jurisdiction in which the foreign court resides, and not U.S. law, is 
applicable to the claim. Further, if U.S. law is found to be applicable, the content of applicable U.S. law 
must  be  proved  as  a  fact,  which  can  be  a  time-consuming  and  costly  process,  and  certain  matters  of 

67

procedure  would  still  be  governed  by  the  law  of  the  jurisdiction  in  which  the  foreign  court  resides.  In 
particular,  there  is  some  doubt  as  to  whether  French  courts  would  recognize  and  enforce  certain  civil 
liabilities  against  us  or  our  Supervisory  Board  or  our  Executive  Board  under  U.S.  securities  laws  in 
original actions or judgments of U.S. courts based upon the civil liability provisions of the U.S. federal 
securities laws.

  In  addition,  awards  of  punitive  damages  in  actions  brought  in  the  United  States  or  elsewhere  may  be 
unenforceable  in  France.  An  award  for  monetary  damages  under  the  U.S.  securities  laws  would  be 
considered punitive if the amount awarded is disproportionate to the harm suffered and the defendant’s 
breach. French law provides that a shareholder, or a group of shareholders, may initiate a legal action to 
seek  indemnification  from  the  directors  of  a  corporation  in  the  corporation’s  interest  if  it  fails  to  bring 
such legal action itself. If so, any damages awarded by the court are paid to the corporation, and any legal 
fees relating to such action may be borne by the relevant shareholder or the group of shareholders. The 
enforceability of any judgment in France will depend on the particular facts of the case as well as the laws 
and treaties in effect at the time. A final judgment for the payment of money rendered by any federal or 
state  court  in  the  United  States  based  on  civil  liability,  whether  or  not  predicated  solely  upon  the  U.S. 
federal  securities  laws,  would  only  be  recognized  and  enforced  in  France  provided  that  a  French  judge 
considers  that  this  judgment  meets  the  French  legal  requirements  concerning  the  recognition  and  the 
enforcement of foreign judgments and is capable of being immediately enforced in the United States. The 
United  States  and  France  do  not  currently  have  a  treaty  providing  for  recognition  and  enforcement  of 
judgments, other than arbitration awards, in civil and commercial matters. 

Innate's bylaws and French corporate law contain provisions that may delay or discourage a takeover 
attempt. 

Provisions contained in the Company's bylaws and French corporate law could make it more difficult for 
a third party to acquire the Company, even if doing so might be beneficial to its shareholders. In addition, 
provisions  of  its  bylaws  impose  various  procedural  and  other  requirements,  which  could  make  it  more 
difficult for shareholders to effect certain corporate actions. These provisions include the following: 

•

•

•

•

under French law, the owner of 90% of the share capital or voting rights of a public company 
listed on a regulated market in a Member State of the European Union or in a state party to the 
EEA  Agreement,  including  from  the  main  French  stock  exchange,  has  the  right  to  force  out 
minority shareholders following a tender offer made to all shareholders; 

under  French  law,  a  non-resident  of  France,  as  well  as  any  French  entity  controlled  by  non-
residents  of  France,  may  have  to  file  a  declaration  for  statistical  purposes  with  the  Bank  of 
France (Banque de France) within 20 working days following the date of certain direct foreign 
investments in us, including any purchase of the Company's ADSs. In particular, such filings 
are required in connection with investments exceeding €15,000,000 that lead to the acquisition 
of at least 10% of the Company's share capital or voting rights or cross such 10% threshold; 

under  French  law,  certain  investments  in  a  French  company  relating  to  certain  strategic 
industries by individuals or entities not residents in a Member State of the EU are subject to 
prior authorization of the Ministry of Economy; 

a  merger  (i.e.,  in  a  French  law  context,  a  share  for  share  exchange  following  which  the 
Company  would  be  dissolved  into  the  acquiring  entity  and  its  shareholders  would  become 
shareholders  of  the  acquiring  entity)  of  the  Company  into  a  company  incorporated  in  the 
European Union would require the approval of the Company's Executive Board, as well as a 
two-thirds  majority  of  the  votes  held  by  the  shareholders  present,  represented  by  proxy  or 
voting by mail at the relevant meeting;

a merger of the Company into a company incorporated outside of the European Union would 
require 100% of its shareholders to approve it; 

under French law, a cash merger is treated as a share purchase and would require the consent 
of each participating shareholder; 

Innate's  shareholders  may  in  the  future  grant  the  Company's  Executive  Board  broad 
authorizations to increase Innate's share capital or to issue additional ordinary shares or other 
securities  (for  example,  warrants)  to  Innate's  shareholders,  the  public  or  qualified  investors, 
including as a possible defense following the launching of a tender offer for Innate's ordinary 
shares; 

its  shareholders  have  preferential  subscription  rights  on  a  pro  rata  basis  on  the  issuance  by 
Innate of any additional securities for cash or a set-off of cash debts, which rights may only be 
waived by the extraordinary general meeting (by a two-thirds majority vote) of the Company's 
shareholders or on an individual basis by each shareholder; 

Innate's  Supervisory  Board  appoints  the  members  of  the  Executive  Board  and  shall  fill  any 
vacancy within two months; 

Innate's Supervisory Board has the right to appoint members of the Supervisory Board to fill a 
vacancy  created  by  the  resignation  or  death  of  a  member  of  the  Supervisory  Board  for  the 
remaining  duration  of  such  member’s  term  of  office,  and  subject  to  the  approval  by  the 
shareholders  of  such  appointment  at  the  next  shareholders’  meeting,  which  prevents 
shareholders from having the sole right to fill vacancies on the Company's Supervisory Board; 

its  Executive  Board  can  be  convened  by  the  chairman  of  the  Executive  Board  or  other 
members of the Executive Board delegated for this purpose; 

its  Supervisory  Board  can  be  convened  by  the  chairman  or  the  vice-chairman  of  the 
Supervisory  Board.  A  member  of  the  Executive  Board  or  one-third  of  the  members  of  the 
Supervisory  Board  may  send  a  written  request  to  the  chairman  to  convene  the  Supervisory 
Board. If the chairman does not convene the Supervisory Board 15 days following the receipt 
of such request, the authors of the request may themselves convene the Supervisory Board; 

its Supervisory Board meetings can only be regularly held if at least half of its members attend 
either  physically  or  by  way  of  videoconference  or  teleconference  enabling  the  members’ 
identification and ensuring their effective participation in the Supervisory Board’s decisions; 

approval  of  at  least  a  majority  of  the  votes  held  by  shareholders  present,  represented  by  a 
proxy, or voting by mail at the relevant ordinary shareholders’ general meeting is required to 
remove  members  of  the  Executive  Board  and/or  members  of  the  Supervisory  Board  with  or 
without cause; 

the  crossing  of  certain  ownership  thresholds  has  to  be  disclosed  and  can  impose  certain 
obligations; 

advance notice is required for nominations to the Supervisory Board or for proposing matters 
to  be  acted  upon  at  a  shareholders’  meeting,  except  that  a  vote  to  remove  and  replace  a 
member  of  the  Supervisory  Board  can  be  proposed  at  any  shareholders’  meeting  without 
notice; 

transfers  of  shares  shall  comply  with  applicable  insider  trading  rules  and  regulations,  and  in 
particular with the Market Abuse Regulation 596/2014 of April 16, 2014, as amended; and 

69

•

pursuant to French law, the Company's bylaws, including the sections relating to the number 
of members of the Executive and Supervisory Boards, and election and removal of members 
of  the  Executive  and  Supervisory  Boards  from  office  may  only  be  modified  by  a  resolution 
adopted  by  two-thirds  of  the  votes  of  the  Company's  shareholders  present,  represented  by  a 
proxy or voting by mail at the meeting. 

Purchasers of ADSs in the U.S. offering are not directly holding the Company's ordinary shares. 

A  holder  of  ADSs  is  not  treated  as  one  of  Innate  Pharma's  shareholders  and  does  not  have  direct 
shareholder rights. French law governs Innate's shareholder rights. The depositary, through the custodian 
or the custodian’s nominee, is the holder of the ordinary shares underlying ADSs held by purchasers of 
ADSs in the U.S. offering. Purchasers of ADSs in the U.S. offering have ADS holder rights. The deposit 
agreement among us, the depositary and purchasers of ADSs in the U.S. offering, as an ADS holder, and 
all other persons directly and indirectly holding ADSs, sets out ADS holder rights, as well as the rights 
and obligations of Innate and the depositary. 

Your right as a holder of ADSs to participate in any future preferential subscription rights offering or 
to elect to receive dividends in shares may be limited, which may cause dilution to your holdings. 

According to French law, if the Company issues additional securities for cash, current shareholders will 
have preferential subscription rights for these securities on a pro rata basis unless they waive those rights 
at  an  extraordinary  meeting  of  its  shareholders  (by  a  two-thirds  majority  vote)  or  individually  by  each 
shareholder. However, Innate's ADS holders in the United States will not be entitled to exercise or sell 
such rights unless the Company registers the rights and the securities to which the rights relate under the 
Securities  Act  or  an  exemption  from  the  registration  requirements  is  available.  In  addition,  the  deposit 
agreement  provides  that  the  depositary  will  not  make  rights  available  to  you  unless  the  distribution  to 
ADS holders of both the rights and any related securities are either registered under the Securities Act or 
exempted  from  registration  under  the  Securities  Act.  Further,  if  the  Company  offers  holders  of  its 
ordinary shares the option to receive dividends in either cash or shares, under the deposit agreement the 
depositary  may  require  satisfactory  assurances  from  Innate  that  extending  the  offer  to  holders  of  ADSs 
does not require registration of any securities under the Securities Act before making the option available 
to holders of ADSs. The Company is under no obligation to file a registration statement with respect to 
any such rights or securities or to endeavor to cause such a registration statement to be declared effective. 
Moreover, the Company may not be able to establish an exemption from registration under the Securities 
Act. Accordingly, ADS holders may be unable to participate in the Company's rights offerings or to elect 
to receive dividends in shares and may experience dilution in their holdings. In addition, if the depositary 
is unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably 
practicable, it will allow the rights to lapse, in which case you will receive no value for these rights. 

You may not be able to exercise your right to vote the ordinary shares underlying your ADSs. 

Holders of ADSs may exercise voting rights with respect to the ordinary shares represented by the ADSs 
only  in  accordance  with  the  provisions  of  the  deposit  agreement.  The  deposit  agreement  provides  that, 
upon  receipt  of  notice  of  any  meeting  of  holders  of  Innate's  ordinary  shares,  the  depositary  will  fix  a 
record  date  for  the  determination  of  ADS  holders  who  shall  be  entitled  to  give  instructions  for  the 
exercise  of  voting  rights.  Upon  timely  receipt  of  notice  from  us,  if  the  Company  so  requests,  the 
depositary shall distribute to the holders as of the record date (i) the notice of the meeting or solicitation 
of  consent  or  proxy  sent  by  Innate  and  (ii)  a  statement  as  to  the  manner  in  which  instructions  may  be 
given by the holders. 

You  may  instruct  the  depositary  of  your  ADSs  to  vote  the  ordinary  shares  underlying  your  ADSs. 
Otherwise, you will not be able to exercise your right to vote, unless you withdraw the ordinary shares 
underlying the ADSs you hold. However, you may not know about the meeting far enough in advance to 

70

withdraw  those  ordinary  shares.  If  the  Company  asks  for  your  instructions,  the  depositary,  upon  timely 
notice from us, will notify you of the upcoming vote and arrange to deliver its voting materials to you. 
The Company cannot guarantee you that you will receive the voting materials in time to ensure that you 
can instruct the depositary to vote your ordinary shares or to withdraw your ordinary shares so that you 
can vote them yourself. If the depositary does not receive timely voting instructions from you, it may give 
a proxy to a person designated by Innate to vote the ordinary shares underlying your ADSs. In addition, 
the  depositary  and  its  agents  are  not  responsible  for  failing  to  carry  out  voting  instructions  or  for  the 
manner of carrying out voting instructions. This means that you may not be able to exercise your right to 
vote, and there may be nothing you can do if the ordinary shares underlying your ADSs are not voted as 
you requested. 

You may be subject to limitations on the transfer of your ADSs and the withdrawal of the underlying 
ordinary shares. 

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books 
at  any  time  or  from  time  to  time  when  it  deems  expedient  in  connection  with  the  performance  of  its 
duties. The depositary may refuse to deliver, transfer or register transfers of your ADSs generally when 
the  Company's  books  or  the  books  of  the  depositary  are  closed,  or  at  any  time  if  the  Company  or  the 
depositary thinks it is advisable to do so because of any requirement of law, government or governmental 
body,  or  under  any  provision  of  the  deposit  agreement,  or  for  any  other  reason  subject  to  your  right  to 
cancel your ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of 
your ADSs and withdrawal of the underlying ordinary shares may arise because the depositary has closed 
its transfer books or the Company has closed its transfer books, the transfer of ordinary shares is blocked 
to permit voting at a shareholders’ meeting or the Company is paying a dividend on its ordinary shares. In 
addition, you may not be able to cancel your ADSs and withdraw the underlying ordinary shares when 
you  owe  money  for  fees,  taxes  and  similar  charges  and  when  it  is  necessary  to  prohibit  withdrawals  in 
order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of 
ordinary shares or other deposited securities. 

As a foreign private issuer, the Company is exempt from a number of rules under the U.S. securities 
laws and is permitted to file less information with the SEC than a U.S. company. 

Innate is a foreign private issuer, as defined in the SEC’s rules and regulations and, consequently, it is not 
subject to all of the disclosure requirements applicable to public companies organized within the United 
States.  For  example,  the  Company  is  exempt  from  certain  rules  under  the  Exchange  Act  that  regulate 
disclosure  obligations  and  procedural  requirements  related  to  the  solicitation  of  proxies,  consents  or 
authorizations applicable to a security registered under the Exchange Act, including the U.S. proxy rules 
under  Section  14  of  the  Exchange  Act.  In  addition,  the  Company's  Executive  Board  and  Supervisory 
Board members are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 
of  the  Exchange  Act  and  related  rules  with  respect  to  their  purchases  and  sales  of  Innate's  securities. 
Moreover, while the Company currently makes annual and semi-annual filings with respect to its listing 
on Euronext Paris and files financial reports on an annual and semi-annual basis, it is not required to file 
periodic  reports  and  financial  statements  with  the  SEC  as  frequently  or  as  promptly  as  U.S.  public 
companies  and  is  not  required  to  file  quarterly  reports  on  Form  10-Q  or  current  reports  on  Form  8-K 
under the Exchange Act. In addition, foreign private issuers are not required to file their annual report on 
Form  20-F  until  four  months  after  the  end  of  each  fiscal  year.  Accordingly,  there  is  and  will  be  less 
publicly available information concerning the Company than there would be if the Company were not a 
foreign private issuer. 

As  a  foreign  private  issuer,  the  Company  is  permitted  to  adopt  certain  home  country  practices  in 
relation  to  corporate  governance  matters  that  differ  significantly  from  Nasdaq  corporate  governance 

71

listing standards, and these practices may afford less protection to shareholders than they would enjoy 
if Innate complied fully with Nasdaq corporate governance listing standards. 

As a foreign private issuer listed on Nasdaq, the Company is subject to their corporate governance listing 
standards.  However,  Nasdaq  rules  permit  foreign  private  issuers  to  follow  the  corporate  governance 
practices of their home country. Some corporate governance practices in France may differ significantly 
from Nasdaq corporate governance listing standards. For example, neither the corporate laws of France 
nor the Company's bylaws require a majority of its Supervisory Board members to be independent, and 
although the corporate governance code to which the Company currently refers (the AFEP/MEDEF code) 
recommends that, in a widely held company like Innate, a majority of the Supervisory Board members be 
independent (as construed under such code), this code only applies on a “comply-or-explain” basis, and 
Innate may in the future either decide not to apply this recommendation or change the corporate code to 
which  it  refers.  Furthermore,  Innate  includes  non-independent  members  of  the  Supervisory  Board  as 
members  of  its  compensation  and  nomination  committee,  and  its  independent  Supervisory  Board 
members do not necessarily hold regularly scheduled meetings at which only independent members of the 
Supervisory  Board  are  present.  Currently,  the  Company  intends  to  follow  home  country  practice  to  the 
maximum extent possible. Therefore, Innate Pharma's shareholders may be afforded less protection than 
they  otherwise  would  have  under  corporate  governance  listing  standards  applicable  to  U.S.  domestic 
issuers.  For  an  overview  of  Innate's  corporate  governance  practices,  see  “Item  16G.—Corporate 
Governance.” 

The  Company  is  an  “emerging  growth  company”  under  the  JOBS  Act  and  is  able  to  avail  itself  of 
reduced  disclosure  requirements  applicable  to  emerging  growth  companies,  which  can  make  its 
ordinary shares ADSs less attractive to investors. We may lose this status from December 31, 2024 and 
will therefore incur additional expenses.

The  Company  is  an  “emerging  growth  company,”  as  defined  in  the  JOBS  Act,  and  it  intends  to  take 
advantage of certain exemptions from various reporting requirements that are applicable to other public 
companies that are not “emerging growth companies,” including not being required to comply with the 
auditor  attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, and exemptions from the 
requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval 
of any golden parachute payments not previously approved. In addition, Section 107 of the JOBS Act also 
provides that an emerging growth company can take advantage of the extended transition period provided 
in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. The 
Company will not take advantage of the extended transition period provided under Section 7(a)(2)(B) of 
the Securities Act for complying with new or revised accounting standards. 

The Company cannot predict if investors will find the ordinary shares or ADSs less attractive because the 
Company  may  rely  on  these  exemptions.  If  some  investors  find  the  ordinary  shares  or  ADSs  less 
attractive as a result, there may be a less active trading market for the ordinary shares or ADSs, and the 
price  of  the  ordinary  shares  or  ADSs  may  be  more  volatile.  Innate  may  take  advantage  of  these 
exemptions until such time that Innate is no longer an emerging growth company. The Company would 
cease to be an emerging growth company upon the earliest to occur of (1) the last day of the fiscal year in 
which Innate Pharma has more than $1.235 billion in annual revenue; (2) the date the Company qualify as 
a  “large  accelerated  filer”  with  at  least  $700  million  of  equity  securities  held  by  non-affiliates;  (3)  the 
issuance,  in  any  three  year  period,  by  Innate  Pharma  of  more  than  $1.0  billion  in  non-convertible  debt 
securities held by non-affiliates; and (4) the last day of the fiscal year ending after the fifth anniversary of 
its  initial  public  offering  of  the  ADSs.  According  to  this  last  criteria,  the  Company  will  not  be  an 
"emerging growth company" from December 31, 2024. 

As a public company, we have incurred and will continue to incur significant legal, accounting and other 
expenses, including costs associated with public company reporting requirements. We may cease to be an 

72

“emerging  growth  company”  on  December  31,  2024,  and  will  therefore  no  longer  eligible  for  reduced 
disclosure  requirements  and  exemptions  applicable  to  emerging  growth  companies.  We  expect  that  our 
loss  of  emerging  growth  company  status  will  require  additional  attention  from  management  and  will 
result in increased costs to us, which could include higher legal fees, accounting fees and fees associated 
with  investor  relations  activities,  among  others.  We  have  also  incurred  and  will  continue  to  incur  costs 
associated with corporate governance requirements, including requirements of the Sarbanes-Oxley Act, as 
well  as  rules  implemented  by  the  SEC  and  Nasdaq  Capital  Market,  which  include  requirements  with 
respect to corporate governance practices of public companies.

The Company may lose its foreign private issuer status in the future, which could result in significant 
additional cost and expense. 

While  Innate  currently  qualifies  as  a  foreign  private  issuer,  the  determination  of  foreign  private  issuer 
status  is  made  annually  on  the  last  business  day  of  an  issuer’s  most  recently  completed  second  fiscal 
quarter and, accordingly, the Company's next determination will be made on June 30, 2024. In the future, 
the Company would lose its foreign private issuer status if the Company fails to meet the requirements 
necessary to maintain its foreign private issuer status as of the relevant determination date. For example, 
if more than 50% of its securities are held by U.S. residents and more than 50% of the members of its 
Executive Board or Supervisory Board are residents or citizens of the United States, Innate could lose its 
foreign private issuer status. 

The regulatory and compliance costs to Innate under U.S. securities laws as a U.S. domestic issuer may 
be significantly more than costs Innate incurs as a foreign private issuer. If the Company is not a foreign 
private issuer, Innate Pharma will be required to file periodic reports and registration statements on U.S. 
domestic issuer forms with the SEC, which are more detailed and extensive in certain respects than the 
forms available to a foreign private issuer. The Company would be required under current SEC rules to 
prepare its financial statements in accordance with U.S. generally accepted accounting principles, or U.S. 
GAAP,  rather  than  IFRS,  and  to  modify  certain  of  its  policies  to  comply  with  corporate  governance 
practices  required  of  U.S.  domestic  issuers.  Such  conversion  of  Innate's  financial  statements  to  U.S. 
GAAP would involve significant time and cost. In addition, the Company may lose its ability to rely upon 
exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to 
foreign  private  issuers  such  as  the  ones  described  above  and  exemptions  from  procedural  requirements 
related to the solicitation of proxies. 

If the Company is a passive foreign investment company, there could be adverse U.S. federal income 
tax consequences to U.S. holders. 

Based  on  Innate's  analysis  of  its  income,  assets,  activities  and  market  capitalization  for  its  taxable  year 
ended December 31, 2023, and although the matter is not free from doubt, the Company believes that it 
was  not  a  passive  foreign  investment  company  (PFIC)  for  the  taxable  year  ended  December  31,  2023. 
However, there can be no assurance that Innate will not be a PFIC in the current year or for any future 
taxable year. Under the Code, a non-U.S. company will be a PFIC for any taxable year in which (1) 75% 
or more of its gross income consists of passive income or (2) 50% or more of the average quarterly value 
of  its  assets  consists  of  assets  that  produce,  or  are  held  for  the  production  of,  passive  income.  For 
purposes  of  these tests,  passive income includes dividends, interest, gains from the sale or exchange of 
investment  property  and  certain  rents  and  royalties  and  passive  assets  generally  includes  cash  and  cash 
equivalents.  In  addition,  for  purposes  of  the  above  calculations,  a  non-U.S.  corporation  that  directly  or 
indirectly  owns  at  least  25%  by  value  of  the  shares  of  another  corporation  is  treated  as  if  it  held  its 
proportionate share of the assets and received directly its proportionate share of the income of such other 
corporation. The status of the Company as a PFIC depends on the composition of its income (including 
whether  reimbursements  of  certain  refundable  research  tax  credits  will  constitute  gross  income  for 
purposes  of  the  PFIC  income  test)  and  the  composition  and  value  of  its  assets.  The  value  of  the 

73

Company’s assets may be determined in large part by reference to the market value of the ordinary shares 
or ADSs, which may fluctuate substantially. The Company’s status as a PFIC may also depend in part on 
the  amount  of  the  amount  of  cash  on  the  Company’s  balance  sheet,  the  cash  proceeds  from  any  fund-
raising activities, and how quickly the Company utilizes such cash in its business. 

If Innate is a PFIC for any taxable year during which a U.S. holder (as defined below under “Item 10E.—
Taxation  –  Material  U.S.  Federal  Income  Tax”)  holds  its  ordinary  shares  or  ADSs,  the  Company  will 
continue to be treated as a PFIC with respect to such U.S. holder in all succeeding years during which the 
U.S. holder owns the ordinary shares or ADSs, regardless of whether the Company continues to meet the 
PFIC test described above, unless the U.S. holder makes a specified election once Innate ceases to be a 
PFIC. If the Company is a PFIC for any taxable year during which a U.S. holder holds its ordinary shares 
or  ADSs,  the  U.S.  holder  may  be  subject  to  adverse  tax  consequences  regardless  of  whether  Innate 
Pharma continues to qualify as a PFIC, including ineligibility for any preferred tax rates on capital gains 
or  on  actual  or  deemed  dividends,  interest  charges  on  certain  taxes  treated  as  deferred,  and  additional 
reporting  requirements.  For  further  discussion  of  the  PFIC  rules  and  the  adverse  U.S.  income  tax 
consequences  in  the  event  the  Company  is  classified  as  a  PFIC,  see  the  section  of  this  Annual  Report 
titled “Item 10E.—Taxation– Material U.S. Federal Income Tax Considerations.” 

If  a  United  States  person  is  treated  as  owning  at  least  10%  of Innate's  ordinary  shares,  such  holder 
may be subject to adverse U.S. federal income tax consequences. 

If  a U.S.  holder is treated as owning, directly, indirectly or constructively, at least 10% of the value or 
voting power of Innate's ordinary shares or ADSs, such U.S. holder may be treated as a “United States 
shareholder”  with  respect  to  each  “controlled  foreign  corporation”  in  its  group,  if  any.  Innate  Pharma 
group  currently  includes  one  U.S.  subsidiary  and,  therefore,  under  current  law  its  current  non-U.S. 
subsidiary  and  any  future  newly  formed  or  acquired  non-U.S.  subsidiaries  will  be  treated  as  controlled 
foreign corporations, regardless of whether the Company is treated as a controlled foreign corporation. A 
United  States  shareholder  of  a  controlled  foreign  corporation  may  be  required  to  annually  report  and 
include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed 
income”  and  investments  in  U.S.  property  by  controlled  foreign  corporations,  regardless  of  whether 
Innate  makes  any  distributions.  An  individual  that  is  a  U.S.  shareholder  with  respect  to  a  controlled 
foreign  corporation  generally  would  not  be  allowed  certain  tax  deductions  or  foreign  tax  credits  that 
would  be  allowed  to  a  U.S.  shareholder  that  is  a  U.S.  corporation.  Failure  to  comply  with  controlled 
foreign  corporation  reporting  obligations  may  subject  a  U.S.  shareholder  to  significant  monetary 
penalties.  The  Company  cannot  provide  any  assurances  that  it  will  furnish  to  any  U.S.  shareholder 
information  that  may  be  necessary  to  comply  with  the  reporting  and  tax  paying  obligations  applicable 
under the controlled foreign corporation rules of the Code. U.S. holders should consult their tax advisors 
regarding the potential application of these rules to their investment in Innate's ordinary shares or ADSs.

B.  Business Overview

Innate  Pharma  S.A.  is  a  global,  clinical-stage  biotechnology  company  developing  immunotherapies  for 
cancer  patients.  Its  innovative  approach  aims  to  harness  the  innate  immune  system  through  therapeutic 
antibodies  and  its  ANKET®  (Antibody-based  NK  cell  Engager  Therapeutics)  proprietary  platform. 
Innate’s portfolio includes lead proprietary program lacutamab, developed in advanced form of cutaneous 
T cell lymphomas and peripheral T cell lymphomas; monalizumab developed with AstraZeneca in non-
small  cell  lung  cancer,  as  well  as  ANKET®  multi-specific  NK  cell  engagers  to  address  multiple  tumor 
types. The Company has developed, internally and through its business development strategy, a broad and 
diversified portfolio including seven clinical product candidates and a robust preclinical pipeline. Innate 
has entered into collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and 
Sanofi.  Innate  Pharma  believes  its  product  candidates  and  clinical  development  approach  are 
differentiated from current immuno-oncology therapies and have the potential to significantly improve the 
clinical outcome for patients with cancer. 

The  immune  system  is  the  body’s  natural  defense  against  invading  organisms  and  pathogens  and  is 
comprised  of  two  arms:  the  innate  immune  system  and  the  adaptive  immune  system.  Recent 
immunotherapy  developments  have  focused  on  generating  a  tumor  antigen-specific  T  cell  response  and 
have  led  to  an  unprecedented  change  in  the  treatment  paradigm  of  many  solid  tumor  cancers.  Despite 
these successes, the breadth and durability of the clinical benefit achieved has been limited to a subset of 
patients  and  tumor  types  because  of  limited  effect  against  solid  tumors  and  toxicity.  The  Company's 
innovative  approach  to  immuno-oncology  aims  to  broaden  and  amplify  anti-tumoral  immune  responses 
by leveraging both the adaptive and the innate immune systems.

The innate immune system is comprised of a variety of cells, including Natural Killer cells (NK cells), 
which are involved in anti-cancer immunosurveillance through a variety of modalities. Activation of the 
innate immune system also helps trigger the adaptive immune system to elicit a response directed against 
specific  antigens  and  can  provide  durable  immune  memory.  Innate's  scientific  expertise,  strategic 
collaborations and discovery engine to seek to harness the potential of the innate immune system.

75

The Company is developing a pipeline of innovative immunotherapies that it believes have the potential 
to provide significant clinical benefits to cancer patients. The following table summarizes Innate's current 
pipeline. 

In  addition  to  these  assets,  the  Company  has  an  active  development  pipeline  with  programs  in  the 
discovery and preclinical stages.

Innate Pharma's collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and 
Sanofi,  allow  Innate  to  leverage  the  expertise  and  resources  of  large  pharmaceutical  companies  and 
research institutions with the goal of accelerating the development, registration and launch of several of 
Innate  Pharma's  assets  while  providing  the  Company  with  financing  to  expand  the  development  of  its 
proprietary  product  candidates.  Over  ten  past  years  the  Company  has  received  an  aggregate  of  $679.2 
million  (€602.8  million)  in  upfront  and  milestone  payments  and  equity  investments  from  its 
collaborations.  This  amount  includes  a  total  of  €62.6  million  received  from  AstraZeneca  following  its 
investment  in  the  Company's  capital  in  October  2018.  Under  Innate's  existing  collaboration  and  license 
agreements  that  become  effective  upon  the  exercise  by  its  collaborators  of  options  to  license  future 
product  candidates,  the  Company  may  be  eligible  to  receive  an  aggregate  of  approximately  up  to  $3.6 
billion  in  future  contingent  payments.  With  respect  to  the  programs  for  which  Innate  Pharma  has  an 
existing  collaboration  or  similar  agreement,  future  contingent  payments  are  dependent  upon  Innate's 
achievement of specified development, regulatory and commercial related milestones. With respect to the 
programs  for  which  Innate  Pharma's  collaborators  have  been  granted  an  option,  future  contingent 
payments  are  dependent  upon  Innate's  collaborators  exercising  such  options,  which  would  result  in  up-
front option exercise fees, and upon its achievement of specific development and sales milestones in those 
particular  programs.  The  aggregate  $3.6  billion  in  future  contingent  payments  assumes  that  its 
collaborators  exercise  all  of  the  options  the  Company  has  granted  to  them  and  that  Innate  achieves  all 
related development, clinical, regulatory and sales milestones. For more information regarding the risks 
related to intellectual property, please see “Risk Factors—Risks Related to Intellectual Property Rights.”

The Company's Strategy

Innate's  goal  is  to  harness  the  immune  system  for  the  treatment  of  oncological  conditions  with  serious 
unmet  medical  need.  By  leveraging  its  extensive  experience  in  immuno-oncology  research  and 
development, the Company strives to continue to discover and develop a broad and diversified portfolio 

76

of first- and best-in-class immunotherapies across various therapeutic modalities. The key elements of its 
strategy include: 

• Drive near-term value with Innate's wholly owned product candidate, lacutamab

◦

Execute the clinical development of its fully owned product candidate, lacutamab, for the 
treatment of patients with cutaneous T cell lymphoma (CTCL), namely Sézary syndrome 
and Mycosis Fungoides (MF), and patients with peripheral T cell lymphoma (PTCL).

• Advance its innovative R&D pipeline

◦

Expand  its  pipeline  of  proprietary  product  candidates  that  target  novel  pathways  in 
immuno-oncology using its internal development engine. 

◦ Drive the development of its proprietary portfolio, including the next generation asset NK 
cell  engagers  (NKCEs)  through  Innate's  proprietary  Antibody-based  NK  cell  Engager 
Therapeutics (ANKET®) platform and continuing to explore Antibody Drug Conjugates 
(ADC) formats.

• Build a sustainable business

◦ Maximize  the  value  of  its  partnered  product  candidates  under  its  various  collaboration, 
license and option agreements, under which the Company has the potential to be eligible 
to receive up to an aggregate of approximately $3.6 billion in future contingent payments, 
including up-front option exercise fees and payments upon the achievement of specified 
development and sales milestones.

◦

Invest  in  the  ongoing  clinical  programs  of monalizumab  for  the  treatment  of  non-small 
cell lung carcinoma (NSCLC).

◦ Continue  to  explore  opportunities  to  accelerate  the  development  of  Innate's  proprietary 

pipeline programs through additional collaborations.

◦ Combine  its  disciplined  business  development  strategy  with  its  immuno-oncology 

research and development capabilities to further expand its product portfolio.

◦ Manage its resources carefully and implement the efficiency measures necessary to 

optimize its resources.

Activating Innate Immunity: Harnessing the Power of Immunotherapy to Treat Cancer 

The Innate Immune System: Gatekeeper of the Adaptive Immune System 

The immune system is the body’s defense against invading organisms and pathogens and is comprised of 
two arms: the innate immune system and adaptive immune system.

The  innate  immune  system  represents  the  first  barrier  of  immune  defense  because  it  reacts  almost 
immediately against threats and serves as a catalyst to mobilize other components of the immune system. 
The  innate  immune  system  functions  to  identify,  attack  and  kill  pathogens  or  cancer  cells,  produce 
cytokines  and  activate  the  complement  cascade  and  the  adaptive  immune  system  through  antigen 
presentation.  These  functions  involve  a  variety  of  cells,  including  NK  cells,  dendritic  cells,  monocytes, 
macrophages  and  neutrophils.  These  cells  then  launch  adaptive  immune  responses  while  also  mounting 
their own effector responses. Throughout the body, cells of the innate immune system play a critical role 
in the immunosurveillance and detection of the formation of cancer cells. 

77

Once  activated,  the  adaptive  immune  system  responds  with  large  numbers  of  effector  cells  directed 
against  specific  antigens  and  can  provide  durable  immune  memory.  An  adaptive  immune  response  is 
highly  specific  to  particular  antigens  expressed  by  pathogens  or  cancer  cells,  but  it  requires  time  to 
develop  in  a  process  known  as  priming.  Key  components  of  the  adaptive  immune  system  include 
antibodies,  which  are  produced  by  B  cells,  bind  to  antigens  and  mark  them  for  destruction  by  other 
immune cells, and T cells, which recognize antigens on diseased cells and then attack and eliminate them. 
The  adaptive  immune  response  is  targeted  and  potent  and  has  the  potential  to  provide  a  long-lasting 
immune memory.

Harnessing  Innate  Immunity  in  Cancer:  NK  Cells  as  a  Key  Player  in  the  Anti-Tumor  Immune 
Response 

NK cells are part of the innate immune system and represent a significant fraction of the total number of 
cytotoxic cells in the body. They are active in many hematological and solid tumors and play a key role in 
the initiation of the T cell response. 

Checkpoints  expressed  on  NK  cells  include  inhibitory  cell  surface  receptors,  such  as  NKG2A,  and 
activating  NK  cell  receptors,  such  as  NKp46.  NKp46  is  the  most  specific  NK  cell  marker  identified  to 
date across organs and species. Other receptors, such as NKG2A, are more prevalent in certain subsets of 
NK  cells,  including  NK  cells  infiltrating  the  tumor,  and  are  also  present  on  tumor  infiltrating  CD8+  T 
cells. 

NK  cells  are  involved  in  the  anti-cancer  immunosurveillance  through  a  variety  of  direct  and  indirect 
effects. The figure below provides an illustration of anti-cancer functions of NK cells.

1 NK cells are able to directly and 

selectively kill cells undergoing stress 
caused by a cancerous transformation or 
pathogen infection, a process called 
natural cytotoxicity.

2 NK cells can also kill target cells when 
they are coated by antibodies in a 
process called antibody-dependent 
cellular cytotoxicity (ADCC).

3 NK cells are also potent producers of 

cytokines, which are soluble molecules 
that recruit and activate an adaptive 
immune response by T cells through 
dendritic or other antigen-presenting 
cells, which in turn may enable the 
generation of immune memory against 
tumor cells.

By  providing  the  initial  catalyst  for  the  multilayered  immune  response,  the  activation  of  the  innate 
immune system through the targeting of NK cells could potentially result in an optimal anti-tumoral T cell 
response.

Innate Pharma's response to cancer: harnessing the innate immunity against cancer

The  Company  has  developed  a  pipeline  around  two  main  innovative  strategies  in  modern  immuno-
oncology:

•

The first of these strategies is to directly target cancer cells through an antibody targeting a tumor 
antigen and causing its destruction. 

◦

◦

◦

Innate's  most  advanced  proprietary  program,  lacutamab,  is  a  potentially  first-in-class 
tumor-targeting  antibody  targeting  KIR3DL2,  seeking  to  induce  the  killing  of  cells 
expressing the tumor antigen. The Company is developing lacutamab for the treatment of 
various  forms  of  T  cell  lymphoma  (TCL),  such  as  CTCL,  including  its  aggressive 
subtype, Sézary syndrome, and PTCL. 
The Company has also developed a proprietary technological platform, named ANKET® 
(for  Antibody-based  NK  cell  Engager  Therapeutics),  which  develops  multi-specific 
antibody  formats  that  leverage  an  activating  receptor,  NKp46.  Its  multi-specific 
antibodies co-engage NKp46, with or without CD16, a tumor antigen and depending on 
the need, a variant of the interleukin-2 (IL-2v) molecule. This approach has the potential 
to  more  effectively  mobilize  NK  cells  than  anti-tumor  cytotoxic  antibodies  because,  in 
the TME of many solid tumors, CD16, the receptor mediating the killing of tumor cells 
by  IgG1  antibodies  can  be  downregulated  on  NK  cells  whereas  NKp46  expression  is 
frequently expressed on tumor-infiltrating NK cells. 

The Company is using its leading antibody engineering capabilities to generate classic 
antibody formats as well as  new products by exploring antibody drug conjugate (ADC) 
formats. 

• Another strategy, known as immuno-oncology, consists in unleashing the immune system against  

cancer. Innate Pharma has developed two approaches: 

◦ Checkpoint inhibitors: the development of antibodies that target immune checkpoints has 
been one of the greatest advances in cancer treatment over the past 10 years. Notably, the 
current approved checkpoint inhibitors target the CTLA-4 and PD-1/PD-L1 pathways on 
T  cells.  These  treatments  have  shown  an  ability  to  activate  T  cells,  shrink  tumors  and 
improve patient survival in a broad range of tumors. The Company is developing broad 
spectrum checkpoint inhibitors targeting inhibitory checkpoints expressed on several cell 
types  in  order  to  potentially  increase  the  breadth  and  quality  of  anti-tumor  response. 
Innate's  most  advanced  checkpoint  inhibitor  product  candidate,  monalizumab,  is 
potentially  a  first-in-class,  dual  checkpoint  inhibitor  designed  to  activate  both  tumor-
infiltrating NK cells and CD8+ T cells, likely resulting in increased effector functions and 
greater  killing  of  the  tumor  by  the  immune  system.  The  Company  has  partnered  with 
AstraZeneca to develop this product, which is currently being tested in a Phase 3 clinical 
trial in unresectable, Stage III non-small cell lung cancer (NSCLC) and a Phase 2 clinical 
trial in resectable, early-stage NSCLC.

◦

Tumor’s  microenvironment  (TME):  the  TME  can  inhibit  both  innate  and  adaptive 
immune  responses  either  by  producing  or  degrading  key  metabolites  or  by  recruiting 
suppressive cells, or both. For example, adenosine is one of the components of the TME 
that most broadly affects immune response. It is produced by the sequential degradation 
of extracellular adenosine triphosphate (ATP) by the following two enzymes: first CD39, 
which degrades the ATP into adenosine monophosphate (AMP), and then second, CD73, 
which  impairs  the  AMP  into  adenosine.  For  this  reason,  this  pathway  has  attracted 

79

significant development efforts that have been focused primarily on the downstream part 
of the adenosine degradation cascade, CD73 and the adenosine receptors. The Company 
is  developing  IPH5301,  a  potentially  best-in-class  anti-CD73  antibody,  and  has  also 
focused on the upstream part of the cascade through IPH5201, an anti-CD39 antibody, in 
order to block the production of immunosuppressive adenosine and increase the pool of 
immuno-stimulatory  extracellular  ATP.  The  Company  believes  this  approach  is  also 
potentially mechanistically synergistic with many therapies such as checkpoint inhibitor, 
tumor-targeting product, etc., as shown by the results of the COAST randomized Phase 2 
study,  where  AstraZeneca's  anti-CD73  oleclumab  in  combination  with  durvalumab 
improved progression-free survival (PFS) and objective response rate (ORR) compared to 
durvalumab  alone  in  patients  with  unresectable,  Stage  III  non-small  cell  lung  cancer 
(NSCLC). Similarly, results from NeoCoast randomized Phase 2 study showed that one 
cycle  of  neoadjuvant  oleclumab  in  combination  with  durvalumab  improved  major 
pathological  response  (MPR)  and  pathological  complete  response  (pCR)  rates  versus 
durvalumab alone, in stage I-IIIA resectable NSCLC patients.

Innate Pharma's Product Pipeline 

Lacutamab (IPH4102), a Tumor Targeting Anti-KIR3DL2 Antibody 

a. Mechanism & Rationale 

The  Company is developing its wholly owned product candidate lacutamab for the treatment of certain 
subtypes of T cell lymphoma (TCLs), including cutaneous T cell lymphoma (CTCL) and peripheral T cell 
lymphoma (PTCL). Lacutamab is designed to bind to the KIR3DL2 receptor and to kill cancer cells by  
antibody dependant cellular phagocytosis (ADCP) and antibody dependant cell cytotoxicity (ADCC), as 
illustrated in the following figure.

KIR3DL2 is a receptor of the killer immunoglobulin like receptor (KIR) family. In its preclinical studies, 
the Company has observed that KIR3DL2 is not expressed on healthy tissues, except on a subset of NK 
cells  (36%)  and  T  cells  (12%  of  CD8+  and  4%  of  CD4+)  (IPH  internal  data).  In  addition,  KIR3DL2  is 
expressed  in  T  cell  lymphoma:  65%  of  CTCL  patients  express  KIR3DL2  with  approximately  50%  of 

80

patients  with  MF,  the  most  common  type  of  CTCL  expressing  KIR3DL2  (Battistella,  2017).  This 
frequency  increases  for  the  most  aggressive  CTCL  subtypes,  including  90%  of  Sézary  syndrome 
(Roelens, 2019). Lastly, approximately 50% of patients with PTCL also express KIR3DL2 (Cheminant, 
ICML Meeting, 2019).

Indication

i.

Cutaneous T Cell Lymphoma

CTCL  is  a  heterogeneous  group  of  non-Hodgkin’s  lymphomas  that  are  characterized  by  the  abnormal 
accumulation of malignant T cells, primarily in the skin. CTCL accounts for approximately 4% of all non-
Hodgkin’s  lymphomas  and  has  a  median  age  at  diagnosis  of  55  to  60  years  (Dobos,  2020;  Fuji,  2020). 
There  are  approximately  2,200-4,000  new  CTCL  cases  diagnosed  per  year  in  Europe  and  the  United 
States combined (SEER Cancer Statistics Review 1975-2017; Dobos, 2020; Zhang, 2019; Gilson, 2019). 
The most common type of CTCL is mycosis fungoides, or MF, accounting for approximately half of all 
CTCLs  (Dobos,  2020,  Bradford,  2009).  Sézary  syndrome,  characterized  by  the  presence  of  lymphoma 
cells in the blood, is a CTCL subtype with a particularly poor prognosis. The following table outlines the 
most common CTCL types, their frequency as a percentage of all cases of CTCL (Dobos, 2020), and the 
prognosis (WHO-EORTC classification 2018 : Willemze, 2019).

Patients  with  advanced  CTCL  have  a  poor  prognosis  with  few  therapeutic  options  and  no  standard  of 
care.  Treatment  generally  includes  skin-directed  therapies,  such  as  topical  corticosteroids,  and  systemic 
treatments,  such  as  steroid  drugs  and  interferon,  for  patients  with  more  advanced  disease  or  for  whom 
skin-directed therapies failed. There are several approved agents for the treatment of CTCL: 

• Bexarotene, approved by FDA in 1999, for use in patients with advanced stage of MF who are 

refractory to at least one prior systemic therapy;

• Vorinostat, approved by FDA in 2006 for the treatment of cutaneous manifestations of CTCL in 
patients with progressive, persistent, or recurrent disease on or following two systemic therapies;

• Denileukin diftitox (DD) approved by the FDA in 2008 for patients with resistant and recurrent 

CTCL;

• Romidepsin, approved by FDA in 2009 for patients with CTCL who have received at least one 

prior systemic therapy;

• Brentuximab vedotin (marketed as Adcetris), was approved by the FDA in 2017 for the treatment 
of  patients  with  primary  cutaneous  anaplastic  large  cell  lymphoma,  or  pcALCL,  or  CD30-

81

expressing  MF  who  have  received  prior  systemic  therapy.  In  Europe,  brentuximab  vedotin  is 
indicated  for  the  treatment  of  adult  patients  with  R/R  CD30+  CTCL  who  require  systemic 
therapy; and

• Mogamulizumab (marketed as Poteligeo), was approved in 2018 by the FDA and the EMA for 
the treatment of adult patients with R/R MF or Sézary syndrome after at least one prior systemic 
therapy.

In  general,  treatment  guidelines  distinguish  CTCL  by  clinical  appearance  and  localization,  histological 
subtype,  extent  and  type  of  extracutaneous  disease,  aggressiveness  and  response  to  previous  treatment. 
Most patients are not suitable for stem cell transplantation due to their age and/or comorbid conditions. 
Although brentuximab vedotin and mogamulizumab represent recent progress in the treatment of CTCL, 
they are still associated with the safety and efficacy limitations observed in their respective clinical trials. 
Further,  even  with  these  options,  the  vast  majority  of  these  treated  patients  eventually  relapse  and  the 
overall survival rate remains poor, which translates to unmet needs that lacutamab aims to address.

In January 2019, the Food and Drug Administration (FDA) granted lacutamab Fast Track Designation for 
the treatment of adults with relapsed/refractory (r/r) Sézary syndrome who have received at least two prior 
systemic therapies. In November 2020, Innate Pharma received Priority Medicines (PRIME) designation 
from the EMA for lacutamab, for the treatment of patients with relapsed or refractory Sézary syndrome 
(SS)  who  have  received  at  least  two  prior  systemic  therapies.  Lacutamab  has  also  been  granted  orphan 
drug designation by the FDA and orphan designation by the EMA for the treatment of CTCL. The U.S. 
Fast-Track and EU PRIME designations support the potential for lacutamab to benefit Sézary Syndrome 
patients in need of new treatment options. The ongoing Phase 2 TELLOMAK trial, initiated in May 2019, 
continues to evaluate lacutamab in different subtypes of TCL.

ii.

Peripheral T Cell Lymphoma

PTCL is a diverse group of aggressive non-Hodgkin’s lymphomas that develop from mature T cells and 
NK cells. PTCL arises in the lymphoid tissues outside of the bone marrow, such as in the lymph nodes, 
spleen,  gastrointestinal  tract  and  skin  (Hsi,  2017).  The  various  PTCL  types,  their  frequency  as  a 
percentage of all TCL cases (Hsi, 2017), and prognosis (Vose, 2018) are shown in the following table.

Irrespective  of  the  specific  regimen  used  (single  agent  chemotherapy  or  combination  chemotherapy 
including Gemcitabine and Oxaliplatin, usually referred to as GemOx), patients with R/R PTCL typically 
experience a poor outcome, with a median progression-free survival and overall survival of 3.1 months 
and 5.5 months, respectively (Mak, 2013). 

Multi-agent chemotherapy is the recommended first line treatment for the majority of patients with PTCL. 
Brentuximab  vedotin  is  approved  in  combination  with  first  line  chemotherapy  for  patients  with  CD30-

82

positive PTCL. For patients who are eligible, subsequent stem cell transplantation is a potentially curative 
option but it is limited to a minority of patients. Despite these treatments, a high proportion of patients 
need  second  line  therapy.  Belinostat  (marketed  as  Beleodaq),  pralatrexate  (marketed  as  Folotyn)  and 
romidepsin  (marketed  as  Istodax)  have  each  been  approved  by  the  FDA  in  this  setting,  but  efficacy  is 
generally  limited.  In  the  respective  non-randomized  clinical  registration  trials,  the  response  rates  to 
belinostat, pralatrexate and romidepsin were each less than 30%, and the median duration of response was 
approximately  10  months  for  belinostat  and  pralatrexate  (O'Connor,  2015  ;  O'Connor,  2011;  Coiffier, 
2012). None of these treatments have been approved by the EMA. 

Despite these approvals, current treatment guidelines (NCCN 2021) recommend participation in a clinical 
trial as a preferred option for patients with relapsed PTCL after first line treatment. If clinical trials are not 
available,  a  chemotherapy  combination  of  gemcitabine  and  oxaliplatin  (GemOx)  is  listed  as  one  of  the 
preferred  treatment  combinations  (ESMO  Lymphoma  Guidelines).  Several  studies  have  been  published 
on the role of GemOx in patients with relapsed lymphoma and it is one of the most widely used regimens 
for this patient population in the United States, Europe and Asia (Mounier, 2013; Yamaguchi, 2012).

c. Clinical Trials

Below is a summary of the clinical trials of lacutamab.

i.

Phase 1 Clinical Trial - CTCL

In  November  2015,  the  lacutamab  Phase  1  dose-escalating  and  cohort  expansion  clinical  trial  was 
initiated  to  evaluate  lacutamab  for  the  treatment  of  advanced  CTCL.  The  trial  was  completed  in  April 
2020, and enrolled 44 patients, including 35 patients with Sézary syndrome, eight patients with mycosis 
fungoides and one patient with CD4+ TCL not otherwise specified. The primary objective of the trial was 
to evaluate lacutamab safety, and to identify dose limiting toxicities (DLTs) and the maximum tolerated 
dose.  Data  from  this  trial  were  presented  at  the  2018  meeting  of  the  American  Society  of  Hematology 
("ASH"), and reported in Lancet Oncology in 2019 by Bagot et al. The Company reported clinical activity 
in the subgroup of 35 Sézary syndrome patients, including an observed overall response rate of 42.9%, 
median  duration  of  response  of  13.8  months,  median  progression-free  survival  of  11.7  months  and 
approximately  90%  of  patients  experienced  an  improved  quality  of  life.  The  overall  response  rate 
appeared to be higher (53.6%) in the 28 patients with no histologic evidence of large cell transformation. 
Clinical  activity  was  associated  with  a  substantial  improvement  in  quality  of  life  as  assessed  by  the 
Skindex29 and Pruritus Visual Analog Scale scores. In a post hoc analysis of seven patients with Sézary 
syndrome  who  were  previously  treated  with  mogamulizumab,  three  (43%)  achieved  a  global  overall 
response  and  three  others  had  stable  disease  as  best  response.  The  remaining  patient  had  a  progressive 

83

disease. The median duration of response in these patients was 13.8 months and median progression-free 
survival was 16.8 months. 

Lacutamab was generally well tolerated. The most common adverse effects (AEs) were peripheral edema 
(27%) and fatigue (20%), all of which were grade 1 or 2. Lymphopenia was the most frequent IPH4102-
related  adverse  event  and  occurred  in  six  (14%)  patients  (three  (7%)  grade  3).  One  patient  developed 
possibly treatment-related fulminant hepatitis six weeks after lacutamab discontinuation and subsequently 
died.  However,  the  patient  had  evidence  of  human  herpes  virus-6B  infection.  Six  possibly  treatment-
related, grade 3 or above adverse events were observed in five patients (11%) and only four patients (9%) 
stopped  treatment  as  a  result  of  an  adverse  event.  One  patient  stopped  treatment  because  of  grade  2 
peripheral  neuropathy,  one  patient  stopped  treatment  because  of  grade  3  general  malaise,  one  patient 
because  of  grade  3  skin  pain  and  one  patient  stopped  treatment  because  of  several  adverse  events, 
including renal injury, respiratory failure, dysphagia and sepsis.

ii.

Phase 2 Clinical Trial (TELLOMAK) - CTCL

1.

Study overview

In  May  2019,  the  Company  initiated  a  global,  open-label,  multi-cohort  Phase  2  clinical  trial,  known  as 
TELLOMAK. This clinical trial is being conducted at approximately 50 sites within the United States and 
Europe    (France,  Italy,  Spain,  Germany,  Belgium,  Poland  and  Austria).  The  trial  aims  to  evaluate  the 
efficacy  and  safety  of  lacutamab  in  patients  with  advanced  T  cell  Lymphoma.  160  patients  have  been 
recruited,  approximately  60  patients  with  Sézary  syndrome  who  have  received  at  least  two  prior 
treatments  (Cohort  1),  and  approximately  100  patients  with  MF  who  have  received  at  least  two  prior 
systemic  therapies  (Cohorts  2,  3  and  all-comers).  Cohorts  2  and  3  recruited  KIR3DL2  expressing  and 
non-expressing  patients  respectively  based  on  an  IHC  assay  for  use  on  frozen  tissue.  The  cohorts  were 
designed  using  Simon  2-stage  approach  which  pre-defined  an  efficacy  threshold  in  Stage  1  before 
continuing to stage 2.  While Cohort 2 continues to Stage 2, the pre-specified threshold for Cohort 3 was 
not met, and was therefore closed in March 2022. 

In March 2022, the Company announced the opening of a new mycosis fungoides (MF) all-comers cohort 
in the TELLOMAK study. The all-comers cohort was planned to recruit both KIR3DL2 expressors and 
non-expressors  to  explore  the  correlation  between  the  level  of  KIR3DL2  expression  and  treatment 
outcomes utilizing a formalin-fixed paraffin embedded (FFPE) assay as a companion diagnostic. 

The following graphic depicts the latest trial design :

The primary endpoint of the trial is objective response rate, measured using the 2011 Olsen criteria for 
CTCL. Key secondary measures include incidence of treatment-emergent AEs, the effect of skin disease 
on quality of life as measured by the Skindex29 questionnaire, pruritus as measured by the Visual Analog 
Scale, progression-free survival and overall survival. The results of the dedicated Sézary syndrome cohort 
may support a future Biologics License Application (BLA) submission to the FDA.

The study started in 2019 and completed enrollment in June 2023 (n=170 patients). 

84

The  TELLOMAK  study  experienced  some  supply  issues  within  2019/2020  which  lead  to  clinical  hold, 
now resolved and summarized below:

•  November  2019,  Impletio  Wirkstoffabfüllung  GmbH  (formerly  known  as  Rentschler  Fill  Solutions 
GmbH),  the  subcontractor  in  charge  of  the  fill-and-finish  manufacturing  operations  of  lacutamab 
unilaterally decided to withdraw the certificates of conformance of all clinical batches produced at their 
facilities, including lacutamab. The company also filed for bankruptcy.

•  Discussions  were  held  with  US  and  European  national  regulatory  authorities  regarding  GMP 
deficiencies  resulting  in  a  suspension  of  enrollment  of  new  patients  into  TELLOMAK  from  December 
2019.

•  In  January  2020,  the  TELLOMAK  trial  in  Sézary  syndrome  and  MF  in  France  and  in  the  United 
Kingdom, was reactivated following authorization by the respective national authorities. In June 2020, the 
FDA lifted the partial clinical hold placed on the TELLOMAK Phase 2 clinical trial, based on a quality 
assessment  of  a  new  GMP-certified  batch  successfully  manufactured  for  the  lacutamab  clinical 
development program, including the TELLOMAK trial. Regulatory agencies in Spain, Germany and Italy 
also  lifted,  in  the  third  quarter  of  2020,  their  partial  clinical  holds  on  the  TELLOMAK  trial,  enabling 
Innate to resume recruitment of the trial in these countries.

Importantly, there were no safety issues related to the trial medication. This is consistent with the review 
conducted  by  the  Independent  Data  Monitoring  Committee  (IDMC),  which  concluded  there  were  no 
safety issues related to lacutamab, and the product appeared to be well-tolerated among current patients 
enrolled  in  the  trial.  Lacutamab  fill  and  finish  manufacturing  operations  were  transferred  to  alternative 
CMOs

In October 2023, the FDA placed a partial clinical hold on the lacutamab IND leading to a pause in new 
patient enrollment to the Company’s lacutamab trials IPH4102-201 (Phase 2 TELLOMAK) and 102 
(Phase 1b PTCL). The partial clinical hold followed one fatal case of hemophagocytic 
lymphohistiocytosis, a rare hematologic disorder. In January 2024, Innate announced that the US Food 
and Drug Administration (FDA) has lifted the partial clinical hold. The FDA decision to lift the partial 
clinical hold is based on the FDA review of the fatal case which Innate, together with a steering 
committee of independent experts, determined to be related to aggressive disease progression and 
lacutamab unrelated. 

Based  on  the  results  of  a  planned  futility  interim  analysis,  however,  and  in  consultation  with  FDA,  the 
Phase 1b study will not enroll additional patients.  Despite objective responses observed, the Company-
sponsored  Phase  1b  clinical  trial  evaluating  lacutamab  as  monotherapy  in  patients  with  KIR3DL2-
expressing refractory/relapsing PTCL will not be reopened to recruitment as the prespecified threshold for 
meaningful clinical activity was not reached.

Clinical results in Sézary Syndrome (SS) (Cohort 1)

•

Final  results  from  the  Phase  2  TELLOMAK  study  in  Sézary  Syndrome  were  presented  at  the 
ASH Meeting in December 2023. 

◦ As  of  May  1,  2023,  the  study’s  data  cutoff,  patients  in  the  Sézary  Syndrome  cohort 
(cohort  1,  n=56)  received  a  median  of  five  prior  systemic  therapies,  including 
mogamulizumab, and had a median follow-up of 14.4 months. 

85

◦

The  data  demonstrated  that  lacutamab  showed  robust  clinical  activity  and  an  overall 
favorable  safety  profile.  The  global  confirmed  objective  response  rate,  or  ORR,  was 
37.5% (21 out of 56), including two complete responses and 19 partial responses. ORR in 
the  skin  was  46.4%  (26  out  of  56),  including  five  complete  responses  and  21  partial 
responses  and  ORR  in  the  blood  was  48.2%  (27  out  of  56)  with  15  CR  and  12  PR. 
Median progression-free survival was 8.0 months (95% confidence interval 4.7-21.2). In 
patients who achieved a global response, the median duration of response is 12.3 months 
(95% confidence interval 5.1-NE). 

Efficacy results in Sézary Syndrome patients (n=56)

Interim clinical results in mycosis fungoides (MF)

•

•

In February 2021, the Company announced that lacutamab demonstrated a positive early signal in 
Cohort 2 testing lacutamab in KIR3DL2 expressing MF patients in the TELLOMAK trial. This 
cohort  reached the pre-determined number of responses needed to advance to stage 2, allowing 
the Company to recruit additional patients. 

The preliminary data from cohorts 2 and 3 were presented at the ICML and EORTC congresses in 
July and October 2021 respectively. Of note, the preliminary data concluded:

•

•

•

•

In MF patients, KIR3DL2 expression ≥ 1% appears to be more associated with advanced 
stage disease and blood and lymph node involvement compared to KIR3DL2 expression 
< 1%.

Lacutamab  showed  high  level  of  clinical  response  in  MF  patients  with  KIR3DL2 
expression ≥ 1% with six global responses (four confirmed and two not confirmed at time 
of DCO but confirmed thereafter) in 17 patients with a median follow-up of 4.8 months. 
Expansion to stage 2 is underway.

In MF patients with KIR3DL2 expression < 1%, expansion to stage 2 would be triggered 
only if one additional confirmed response is observed during follow-up.

Lacutamab  shows  favorable  safety  profile  in  MF,  with  no  relevant  skin  toxicities 
observed. 

86

•

Long-term follow-up is required to provide mature conclusions on duration of response 
and progression free survival.

•

In  September  2022,  MF  Cohorts  2  and  3  Stage  1  interim  data  were  presented  at  the  EORTC 
congress. As of the March 4, 2022 data cutoff:

◦

◦

Patients  in  the  KIR3DL2  ≥1%  subgroup  (cohort  2)  received  a  median  of  four  prior 
systemic therapies, and had a median follow-up of 12.2 months. Objective response rate 
(ORR) was 28.6% (95% CI 13.8-50.0) including two complete responses and four partial 
responses.  Median PFS was 12.0 months (4.6-15.4) and Median Duration of Response 
was 10.2 months (4.6-NA).  

Patients  in  the  KIR3DL2  <1%  subgroup  (cohort  3)  received  a  median  of  4.5  prior 
systemic  therapies  and  had  a  median  follow-up  of  13.8  months.  ORR  was  11.1% 
(3.1-32.8) with a median PFS of 8.5 months (4.1-NA)

◦ Within  the  advanced  and  heavily  pre-treated  population  enrolled  in  TELLOMAK, 
Lacutamab continues to demonstrates clinical activity with a favorable safety profile. 

◦

Lacutamab  showed  low  immunogenicity  and  reached  target  concentration  in  both  the 
KIR3DL2 expressing and non-expressing patients. 

•

In    2023,  MF  Cohorts  2  and  3  interim  efficacy  results  according  to  updated  guidelines  were 
presented  at  the  International  Conference  on  Malignant  Lymphoma  and  EORTC  Cutaneous 
Lymphoma Tumour Group Annual Meeting  congresses in June and October 2023, respectively. 

◦ As  of  the  March  4,  2022  data  cutoff,  patients  in  the  KIR3DL2-expressing  MF  cohort 
(cohort  2,  n=21)  received  a  median  of  4  prior  systemic  therapies,  and  had  a  median 
follow-up  of  12.2  months.  In  the  KIR3DL2  non-expressing  cohort  (cohort  3,  n=18), 
patients received a median of 4.5 prior systemic therapies and had a median follow-up of 
13.8 months. 

◦

Lymph Node assessment is an important component of staging and response assessment 
in CTCL (cutaneous T cell lymphomas). In a recent update to the Olsen 2011 guidelines, 
it was clarified that the pathological assessment of lymph nodes be limited to those that 
satisfy nodal lymphoma i.e. N3 designation (Olsen 2021). Based on these criteria, results 
showed  that  lacutamab  produced  an  increased  global  objective  response  rate  (ORR)  of 
42.9%  (95%  confidence  interval  [CI],  24.5-63.5)  in  patients  with  KIR3DL2  ≥  1%  MF 
(cohort 2, n=21), including 2 complete responses and 7 partial responses. Clinical Benefit 
Rate  remained  unchanged  at  85.7%  [95%  CI  tbc].  In  Cohort  3,  comprising  18  patients 
with KIR3DL2 < 1% MF, findings remain unchanged.

•

Top-line  final  results  for  MF  Cohorts  2  and  3  are  expected  in  2024  and  when  available  Innate 
expects to share them at an upcoming medical conference. 

iii.

Clinical Trials in PTCL

• Despite objective responses observed, the Company-sponsored Phase 1b clinical trial evaluating 
lacutamab as monotherapy in patients with KIR3DL2-expressing refractory/relapsing PTCL will 

87

not be reopened to recruitment as the prespecified threshold for meaningful clinical activity was 
not reached.

• At the ASH Annual Congress 2023, Innate presented a poster with preclinical  data demonstrating 
a  synergistic  effect  between  lacutamab  and  chemotherapy  in  preclinical  models  of  PTCL, 
supporting the rationale for combination strategy in this clinical indication. 

•

The Phase 2 KILT (anti-KIR in T Cell Lymphoma) trial, an investigator-sponsored, randomized 
trial led by the Lymphoma Study Association (LYSA) to evaluate lacutamab in combination with 
chemotherapy GEMOX (gemcitabine in combination with oxaliplatin) versus GEMOX alone in 
patients with KIR3DL2-expressing relapsed/refractory PTCL is ongoing.

Monalizumab, a Dual Checkpoint Inhibitor Targeting T Cells and NK Cells 

a. Mechanism & Rationale 

Monalizumab  (IPH2201)  is  a  potentially  first-in-class  immune  checkpoint  inhibitor  targeting  NKG2A 
receptors expressed on tumor infiltrating cytotoxic CD8+ T cells and NK cells. NKG2A is an inhibitory 
receptor  for  HLA-E.  HLA-E  is  frequently  overexpressed  in  the  cancer  cells  of  many  solid  tumors  and 
hematological malignancies. By expressing HLA-E, cancer cells can protect themselves from killing by 
NKG2A+ immune cells. Monalizumab may reestablish a broad anti-tumor response mediated by NK and 
T cells, and may enhance the cytotoxic potential of other therapeutic antibodies (André et al., Cell 2018).

b. Rationale for combinations with monalizumab 

The  Company  is  primarily  focused  on  investigating  monalizumab  in  combination  with  durvalumab, 
which is an antibody directed against PD-L1. PD-L1 and HLA-E are both up-regulated on many cancer 
cells,  and  they  have  both  been  observed  to  suppress  tumor  immune  response  and  contribute  to  tumor 
progression. Innate Pharma's preclinical data support its hypothesis that a monalizumab and durvalumab 

88

combination  therapy  may  result  in  a  greater  anti-tumor  immune  response  than  durvalumab  alone  by 
blocking both the PD-1/PD-L1 and the NKG2A/HLA-E inhibitory pathways. 

The  following  illustration  depicts  the  way  in  which  monalizumab,  in  combination  with  durvalumab,  is 
designed to result in greater anti-tumor activity.

The  rationale  for  this  combination  is  further  supported  by  the  favorable  tolerability  profile  of 
monalizumab that the Company observed in preclinical studies and earlier clinical trials, suggesting that 
monalizumab  is  generally  not  expected  to  negatively  impact  the  safety  profile  of  combination  partner 
drugs. 

c. Clinical Development Plan

i.

Overview

Monalizumab  has  been  evaluated  in  clinical  trials  in  head  and  neck,  lung  and  other  cancer  indications. 
Innate  is  responsible  for  the  conduct  of  the  IPH2201-203  study  in  head  and  neck  squamous  cell 
carcinoma, while AstraZeneca is conducting all other trials (except for the External Sponsored studies). 

89

Below  is  a  summary  of  ongoing  clinical  trials  in  NSCLC  that  AstraZeneca  is  conducting  to  evaluate 
monalizumab:

ii. Clinical Development Plan in Lung Cancer 

Lung  cancer  is  the  leading  cause  of  cancer  death,  accounting  for  about  one-third  of  all  cancer 
deaths. In 2020, an estimated 2.2 million people were diagnosed with lung cancer worldwide. Eighty to 
eighty-five percent are  classified as NSCLC. Stage III NSCLC represents approximately one quarter of 
NSCLC  incidence.  In  2018,  the  FDA  approved  durvalumab  for  patients  with  unresectable  stage  III 
NSCLC  whose  disease  has  not  progressed  following  concurrent  platinum-based  chemotherapy  and 
radiation therapy. However, there is still a need for new treatment options to further increase the potential 
for  cure  in  this  setting.  AstraZeneca  conducted  COAST,  a  randomized  Phase  2  trial  investigating 
durvalumab  alone  or  in  combination  with  either  oleclumab  (anti-CD73  monoclonal  antibody)  or 
monalizumab (anti-NKG2A monoclonal antibody) in patients with locally advanced, unresectable Stage 
III NSCLC who had not progressed after chemoradiotherapy (CRT). Following on the signal observed in 
this Phase 2 study, AstraZeneca has started a randomized Phase 3 study PACIFIC-9 of monalizumab or 
oleclumab  plus  durvalumab  in  unresectable,  Stage  III  NSCLC  setting  for  patients  who  have  not 
progressed after concurrent chemoradiation therapy.  

Separately, AstraZeneca evaluated the effectiveness and safety of neoadjuvant durvalumab alone 
or  in  combination  with  monalizumab  or  oleclumab  in  subjects  with  resectable,  early-stage  (Stage  I  [>2 
cm]  to  IIIA)  non-small  cell  lung  cancer  (NeoCOAST)  and  in  2022  initiated  the  Phase  2  trial, 
NeoCOAST-2,  with  neoadjuvant  and  adjuvant  treatment,  that  includes  an  arm  with  durvalumab  in 
combination with chemotherapy and monalizumab.

iii. Clinical Development Plan in Head and Neck Cancer 

In head and neck cancer, Innate and AstraZeneca evaluated monalizumab in combination with cetuximab 
in R/M SCCHN IO naïve or IO-pretreated in a Phase 1b/2 study (IPH2201-203). Based on the results and 
the unmet need in the IO-pretreated population, AstraZeneca and Innate elected to advance this program 
to  a  Phase  3  study  (INTERLINK-1).  Dosing  of  the  first  patient  in  this  trial  triggered  a  $50  million 

90

milestone  payment  from  AstraZeneca  to  Innate  in  October  2020.  In  2022,  Innate  shared  that  a  planned 
futility  interim  analysis  of  the  INTERLINK-1  Phase  3  study  sponsored  by  AstraZeneca  did  not  meet  a 
pre-defined threshold for efficacy. Based on this result and the recommendation of an Independent Data 
Monitoring Committee, AstraZeneca informed Innate that the study would be discontinued. There were 
no new safety findings. 

•

IPH2201-203 was an open-label, Phase 1b/2 clinical trial in combination with cetuximab and/or 
durvalumab  in  patients  with  R/M  SCCHN.  This  study,  sponsored  by  Innate  Pharma  started  in 
December 2015 and the last patient last visit was  in March 2023. The study included :

▪

a Phase 1b dose-escalation portion

a Phase 2 portion comprising three expansion cohorts: 

◦ Cohort  1,  which  enrolled  43  patients,  evaluated  the  combination  of  monalizumab  and 
cetuximab in patients with recurrent or metastatic squamous cell carcinoma of the head 
and  neck  (R/M  SCCHN)  who  had  been  previously  treated  with  chemotherapy  alone  or 
chemotherapy followed by checkpoint inhibitors; 

◦ Cohort 2, which enrolled 41 patients and evaluated the combination of monalizumab and 
cetuximab  in  patients  with  R/M  SCCHN  who  have  received  a  maximum  of  two  prior 
systemic  regimens  in  the  R/M  setting  and  with  prior  exposure  to  a  PD-(L)1  inhibitor 
(who Innate refers to as IO-pretreated patients); and 

◦ Cohort  3,  which  enrolled  40  patients,  began  recruiting  in  April  2019  and  evaluated  the 
combination of monalizumab, cetuximab and durvalumab in IO-naïve patients with R/M 
SCCHN. 

•

Interlink-1 was a global, multi-center, randomized, double-blind Phase 3 study of monalizumab 
and cetuximab vs. placebo and cetuximab designed to enroll approximately 600 patients with 
recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) who have 
been previously treated with platinum-based chemotherapy and PD-(L)1 inhibitors (“IO-
pretreated”). The study started on October 2, 2020 and on August 1, 2022, the company 
announced that the study will be discontinued. 

d. Clinical Results

i.

Lung Cancer: Phase 2 COAST Study

In  September  2021,  AstraZeneca  presented  a  late-breaker  abstract  on  the  randomized  COAST  Phase  2 
trial in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) at the European Society 
for  Medical  Oncology  (ESMO)  Congress.  The  presentation  highlighted  progression-free  survival  (PFS) 
and overall response rate (ORR) results for durvalumab in combination with monalizumab, Innate’s lead 
partnered asset, and oleclumab, AstraZeneca’s anti-CD73 monoclonal antibody. After a median follow-up 
of 11.5 months, the results of an interim analysis showed a 10-month PFS rate of 72.7% for durvalumab 
plus  monalizumab,  versus  39.2%  with  durvalumab  alone  in  unresectable,  Stage  III  NSCLC  patients 
following  chemoradiation  therapy.  The  results  also  showed  an  increase  in  the  primary  endpoint  of 
confirmed  ORR  for  durvalumab  plus  monalizumab  over  durvalumab  alone  (36%  vs.  18%).  Data  are 
published in the Journal of Clinical Oncology in 2022 (figure below).

ii.

Lung Cancer: Phase 2 NeoCOAST Study

In March 2022, the Phase 2 NeoCOAST multi-drug platform study assessing the safety and efficacy of 
neoadjuvant durvalumab in combination with chemotherapy and oleclumab,  monalizumab or danvatirsen 
and  adjuvant  treatment  in  participants  with  resectable,  early-stage  non-small  cell  lung  cancer  was 
accepted  for  an  oral  presentation  on  April  11,  2022  at  the  Annual  Meeting  2022  of  the  American 
Association  for  Cancer  Research  (AACR).”  The  study  demonstrated  that  a  single  cycle  of  neoadjuvant 
durvalumab  combined  with  oleclumab,  monalizumab,  or  danvatirsen  produced  numerically  improved 
MPR rates (19, 30 and 31.2%, respectively) compared with durvalumab alone (11.1%).  No differences in 
pCR rates were observed between treatment arms. 

iii.

Lung Cancer: Phase 3 PACIFIC-9 

In June 2023, AstraZeneca presented at the ASCO conference a trial-in-progress poster on the PACIFIC-9 
study:  "Phase  3  study  of  durvalumab  combined  with  oleclumab  or  monalizumab  in  patients  with 
unresectable stage III NSCLC (PACIFIC-9)." 

PACIFIC-9 started in February 2022 and continues to enroll patients. 

iv.

Lung Cancer: Phase 2 NeoCOAST-2 

In  June  2023,  AstraZeneca  presented  at  the  ASCO  conference  a  trial-in-progress  poster  on  the 
NeoCOAST-2:  study:  "NeoCOAST-2:  A  Phase  2  study  of  neoadjuvant  durvalumab  plus  novel 
immunotherapies (IO) and chemotherapy (CT) or MEDI5752 (volrustomig) plus CT, followed by surgery 
and  adjuvant  durvalumab  plus  novel  IO  or  volrustomig  alone  in  patients  with  resectable  non-small-cell 
lung cancer (NSCLC)."  

NeoCOAST-2 started in April 2022 and continues to enroll patients.

v.

Head and Neck Cancer: IPH2201-203 Study

•

Phase 2: Expansion cohort 1

The primary endpoint for the Phase 2 portion of the trial is objective response rate, which is measured as 
the  rate  of  patients  who  had  a  complete  or  partial  response  according  to  RECIST  1.1.  Secondary 
endpoints for the Phase 2 portion of the trial include duration of response, progression-free survival and 
overall survival.

As of April 30, 2019, 40 patients were enrolled globally. The monalizumab and cetuximab combination 
demonstrated  an  acceptable  safety  profile.  The  trial  was  declared  positive,  as  the  required  predefined 
number of at least eight responses was reached with an ORR of 27.5% (36% and 17% in IO naïve and IO 
pretreated patients, respectively). With a median follow-up of 17 months (mo), median OS is 8.5 mo with 
a trend for improved survival in IO-pretreated patients (14.1 mo in IO-pretreated patients and 7.8 in IO 
naïve  patients,  respectively)  and  12  mo  OS  rate  of  44%  (60%  in  IO-pretreated  and  32%  in  IO  naïve 
patients, respectively). 

•

Phase 2: Expansion cohort 2

As of August 31, 2020, 40 patients with R/M SCCHN post platinum and anti-PD-(L)1 were included in 
cohort  2  in  the  United  States  and  France.  Median  duration  of  follow-up  (FU)  was  13.1  months  (range 
7.9-15.9). 

The monalizumab and cetuximab combination therapy demonstrates a good safety profile and promising 
activity in R/M SCCHN post platinum and post anti-PD-(L)1 where no treatment options were currently 
approved.  In  this  population  with  a  high  medical  need,  the  Company  observed  a  high  response  rate  of 
20%  and  promising  6-  and  12-month  OS  of  80%  and  33%  with  monalizumab  combined  with 
cetuximab. These results were presented at the ESMO IO conference in 2020. 

Based  on  these  results,  a  randomized  Phase  3  trial,  INTERLINK-1,  was  started  to  evaluate  the 
combination monalizumab + cetuximab versus cetuximab + placebo in R/M SCCHN post platinum and 
post anti-PD-(L)1 patients.

•

Phase 2: Expansion cohort 3

As of August 1, 2021, 40 patients were enrolled in the cohort 3 evaluating monalizumab, cetuximab and 
durvalumab  in  first  line  treatment  of  R/M  SCCHN.  Median  follow-up  was  16.3  months  (4.4-25.7); 
13 patients had a confirmed response, ORR=32.5% [95%CI: 20-48], including three complete responses. 
Median time to response was 1.8 months [1.6-3.7]. 6/13 responders were still on treatment, with median 
duration of response not yet reached [7.1-NR]. Median PFS was 6.9 months [4.4-9.3], and 12 months OS 
was 59% [45-77].  These results were presented at the ESMO IO conference in 2021. 

vi.

Head and Neck Cancer: INTERLINK-1

Interlink-1  was  a  global,  multi-center,  randomized,  double-blind  Phase  3  study  of  monalizumab  and 
cetuximab  vs.  placebo  and  cetuximab  designed  to  enroll  approximately  600  patients  with  recurrent  or 
metastatic  squamous  cell  carcinoma  of  the  head  and  neck  (R/M  SCCHN)  who  have  been  previously 
treated with platinum-based chemotherapy and PD-(L)1 inhibitors (“IO-pretreated”). On August 1, 2022, 
the company announced that a planned futility interim analysis did not meet a pre-defined threshold for 
efficacy.  Based  on  this  result  and  the  recommendation  of  an  Independent  Data  Monitoring  Committee, 
AstraZeneca informed Innate that the study would be discontinued. There were no new safety findings. 
Clinical data presented at the ESMO conference on October 23, 2023 showed that OS and PFS were not 

93

improved with monalizumab plus cetuximab versus placebo plus cetuximab; and that ORR in the placebo 
plus  cetuximab  arm  was  higher  than  in  previous  reports  of  participants  with  R/M  HNSCC  with 
progression  on  /  after  platinum  therapy.  Exploratory  biomarker  analyses  are  ongoing  to  identify 
subpopulations that may benefit from monalizumab plus cetuximab treatment. 

vii.

Phase 1/2 Clinical Trial in Solid Tumors, including Colorectal Cancer (in combination 
with durvalumab): D419NC00001

AstraZeneca has evaluated monalizumab in combination with durvalumab in a Phase 1/2 clinical trial in 
383 patients with advanced solid tumor malignancies. The study consisted of three parts: dose escalation 
(Part 1), dose expansion (Part 2) and dose exploration (Part 3). In 2018, clinical data showed preliminary 
anti-tumor  activity  in  patients  with  recurrent/metastatic  microsatellite-stable  colorectal  cancer  (MSS-
CRC),  a  population  historically  unresponsive  to  PD-1/L1  blockade.  Thirty-one  percent  disease  control 
rate  at  16  weeks  (DCR:  %  of  responses  and  stable  disease)  suggested  that  patients  may  benefit  from 
stabilizing  effect  when  88%  of  patients  had  two  or  more  prior  lines  of  therapy  for  recurrent/metastatic 
disease. These data formed a basis for exploring the combination with standard of care therapies (SoC) in 
less heavily pretreated patients. 

e.

Partnership with AstraZeneca

On  April  24,  2015,  the  Company  signed  a  co-development  and  commercialization  agreement  with 
AstraZeneca  to  accelerate  and  broaden  the  development  of  monalizumab.  AstraZeneca  obtained  full 
oncology rights to monalizumab in October 2018. The financial terms of the agreement include potential 
cash  payments  of  up  to  $1.275  billion  to  Innate  Pharma.  With  the  addition  of  the  $50  million  payment 
triggered by dosing the first patient in the Phase 3 PACIFIC-9 clinical trial, Innate Pharma has received 
$450  million  to  date.  AstraZeneca  will  book  all  sales  and  will  pay  Innate  low  double-digit  to  mid-teen 
percentage  royalties  on  net  sales  worldwide  except  in  Europe  where  Innate  Pharma  will  receive  if  it 
chooses to co-promote the licensed products in certain European countries a 50% share of the profits and 
losses in these territories. Should Innate Pharma elect not to co-promote, its share of profits in Europe will 
be reduced by a specified amount of percentage points not to exceed the mid-single digits. Innate will co-
fund 30% of the costs of the Phase 3 development program of monalizumab with a pre-agreed limitation 
on Innate’s financial commitment.

IPH5201, an Anti-CD39 Antibody Targeting the Immunosuppressive Adenosine Pathway 

a. Mechanism & Rationale 

CD39  is  an  extracellular  enzyme  that  is  expressed  in  the  tumor  microenvironment,  on  both  tumor 
infiltrating cells and stromal cells in several cancer types. CD39 inhibits the immune system by degrading 
adenosine  triphosphate  (ATP)  into  adenosine  monophosphate  (AMP),  that  is  then  further  degraded  into 
adenosine  by  CD73.  By  promoting  the  accumulation  of  immune-stimulating  ATP,  and  preventing  the 
production of immune-suppressive adenosine, the blockade of CD39 may stimulate anti-tumor activity.

IPH5201 is a blocking antibody targeting the CD39 immunosuppressive pathway.

94

Targeting  the  adenosine  pathway  has  recently  been  reported  to  improve  Durvalumab  (anti-PD-L1) 
efficacy in early-stage Non-Small Cell Lung Cancer (NSCLC) patients, through the use of Oleclumab, an 
anti-CD73  mAb.  Indeed,  in  the  COAST  randomized  Phase  2  study,  oleclumab  in  combination  with 
durvalumab  improved  progression-free  survival  (PFS)  and  objective  response  rate  (ORR)  compared  to 
durvalumab alone in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) (Herbst, 
JCO,  2022).  Also,  in  the  NeoCoast  randomized  Phase  2  study,  one  cycle  of  neoadjuvant  oleclumab  in 
combination  with  durvalumab  improved  major  pathological  response  (MPR)  and  pathological  complete 
response  (pCR)  rates  versus  durvalumab  alone,  in  stage  I-IIIA  resectable  NSCLC  patients  (Cascone, 
AACR 2022). 

This  supports  the  evaluation  of  the  combined  blockade  of  CD39  and  PD-L1,  with  IPH5201  and 
durvalumab,  respectively,  that  can  hypothetically  increase  activity  when  compared  to  durvalumab 
monotherapy by altering the balance of ATP and adenosine in the tumor microenvironment. 

b. Non Clinical Development

The  rationale  is  supported  by  the  analysis  of  anti-tumor  immune  responses  in  tumor-challenged  CD39 
deficient mice and by its non-clinical data for IPH5201 in mouse tumor models.

CD39-deficient  mice  are  more  resistant  to  developing  lung  or  liver  metastatic  tumors  after  systemic 
challenge  with  syngeneic  B16F10  or  MC38  tumor  cells  (Sun,  2010).  Subcutaneous  (SC)  syngeneic 
B16F10  tumors  also  grew  more  slowly  in  CD39-deficient  mice,  leading  to  improved  overall  survival 
versus wild-type mice, and correlated with reduced angiogenesis and improved effector function of tumor 
infiltrating  T  cells  in  CD39-deficient  mice  (Jackson,  2007;  Sun,  2013).  Furthermore,  CD39  deficiency 
enhanced the anti-tumor activity of PD-1 blocking antibodies alone and in combination with oxaliplatin 
chemotherapy in tumor-bearing mice (Perrot, 2019).

The Company's non-clinical studies demonstrated that IPH5201 blocking CD39 mAb effectively targets 
and inhibits CD39 (soluble and membrane form) activity, reverses adenosine-mediated T cell suppression, 
and  enhances  ATP-dependent  macrophages  and  DC  activation  (adenosine  independent).  IPH5201 
synergized  with  a  blocking  mAb  against  CD73  to  restore  activation  of  T  cells  isolated  from  cancer 
patients  in  vitro  (Perrot,  2019).  In  syngeneic  tumor-bearing  human  CD39  knock-in  mice,  the  Company 
observed that a mouse version of IPH5201 enhanced the antitumor effects of PD-L1 blockade.

95

CD39  is  expressed  in  both  squamous  and  adenocarcinoma  subtypes  of  NSCLC  with  expression  noted 
across  disease  stages  (Anceriz,  ESMO-IO  2022,  Poster  190P,  abstract  384).  In  a  mouse  tumor  model 
engrafted in huCD39KI mice, moIPH5201 was able to decrease the human CD39 enzymatic activity and 
to lower the Ado level in situ. In vitro, chemotherapies induced extracellular ATP release by tumor cells 
and  IPH5201  was  able  to  accumulate  the  released  ATP,  following  chemotherapy  treatment.  Finally,  as 
shown in the figure below, in vivo, in a mouse tumor model engrafted in huCD39KI mice, moIPH5201 
improved  the  anti-tumor  efficacy  of  gemcitabine  and  anti-PD-L1  combination.  The  three  graphs  on  the 
left (A) show the best tumor volume change in percentage, for each treated group in comparison to the 
control group. The diagram on the right outlines survival in each group.

Altogether, the expression profile of CD39 in early-stage NSCLC and preclinical combination data 
support the clinical evaluation of IPH5201 in combination with Durvalumab and chemotherapies in early-
stage NSCLC patients.

 Clinical development

i. Overview and indications

IPH5201  has  been  evaluated  in  a  Phase  1  clinical  in  advanced  solid  tumors,  in  monotherapy  and  in 
combination  with  durvalumab;  and  is  being  investigated  in  a  Phase  2  clinical  trial,  MATISSE,  in 
combination with durvalumab and chemotherapy in non-small cell lung cancer (NSCLC). 

96

Lung cancer is the second most common cancer in both men and women, with an estimated 234,030 new 
cases  of  lung  cancer  in  the  United  States  in  2018,  and  remains  the  main  cause  of  cancer-related  deaths 
worldwide. Resectable, early-stage NSCLC is considered a potentially curable disease, and the standard 
of  care  is  surgery  alone  or  surgery  with  adjuvant  or  neoadjuvant  platinum-based  doublet  chemotherapy 
(NCCN 2022). However, patients had five-year survival rates ranging from approximately 70% for Stage 
IA1 NSCLC to 20% for Stage IIIA NSCLC (Chansky, 2017). 

Recently,  the  role  of  PD-1/PD-L1  inhibition  has  been  evaluated  for  the  treatment  of  resectable, 
early-stage  NSCLC  in  adjuvant  and  neoadjuvant  setting  and  led  to  improved  outcomes  and  recent 
approval (Nivolumab/Checkmate 816 and Pembrolizumab/KEYNOTE-671). Recent interim data from the 
Phase  III  AEGEAN  study  (NCT03800134)  showed  that  perioperative  durvalumab  (anti-PD-L1)  plus 
neoadjuvant  CT  significantly  improved  both  pathological  complete  response  (pCR)  rate  (17.2%  in  the 
durvalumab-based  regimen  arm  vs  4.3%  in  the  CT  arm)  and  Event-Free  Survival  (EFS)  (median  not 
reached in the durvalumab-based regimen arm vs 25.9 months in the CT arm) in patients with resectable, 
Stage IIA–IIIB[N2] NSCLC. 

ii.

Phase I  in advanced solid tumors

A Phase 1 clinical trial (NCT04261075), sponsored by AstraZeneca, with first patient treated in 
March  2020,  evaluated  IPH5201,  an  anti-CD39  blocking  monoclonal  antibody,  in  adult  patients  with 
advanced  solid  tumors.  The  purpose  of  the  study  was  to  evaluate  IPH5201  as  monotherapy  and  in 
combination  with  durvalumab  (anti-PD-L1)  and  with  or  without  oleclumab  (anti-CD73  monoclonal 
antibody).  This  multicenter,  open-label,  dose-escalation  Phase  1  study  evaluated  the  safety,  tolerability, 
antitumor  activity,  pharmacokinetics  (PK),  pharmacodynamics  (PD)  and  immunogenicity  of  IPH5201 
alone,  or  in  combination  with  AstraZeneca’s  anti-PD-L1  therapy,  durvalumab,  with  or  without  its  anti-
CD73 monoclonal antibody, oleclumab. 

The  current  study  status  is  completed  and  results  were  presented  at  the  ESMO-IO  congress 
(Imbimbo,  Poster  188P,  abstract  472).  IPH5201  was  well  tolerated  when  used  alone  or  in  combination 
with  durvalumab  up  to  a  dose  of  3000  mg  Q3W.  The  safety  profile  was  manageable,  with  the  most 
common  treatment-related  adverse  events  being  infusion-related  reactions  and  fatigue;  no  new  safety 
signals  were  identified  beyond  those  observed  with  durvalumab  monotherapy.  No  maximum  tolerated 
dose (MTD) was identified. PK of IPH5201 was non-linear at ≤300 mg and linear at ≥1000 mg. The PD 

97

profile,  including  inhibition  of  CD39  activity  in  the  tumors  of  patients  treated  with  IPH5201,  was 
consistent with the proposed mechanism of action for IPH5201. 

As clinical activity results, 22/57 patients (38.6%) had stable disease as their best overall response; there 
were no partial or complete responses. In IPH5201 monotherapy subgroup, 17/38 patients (44.7%)  had 
stable disease as their best overall response

iii.

Phase II MATISSE study in NSCLC

MATISSE  is  a  Phase  2  multicenter  single-arm  study  (NCT05742607),  sponsored  by  Innate  Pharma, 
evaluating  neoadjuvant  and  adjuvant  treatment  with  IPH5201,  an  anti-CD39  blocking  monoclonal 
antibody,  in  combination  with  durvalumab  (anti-PD-L1)  and  chemotherapy,  in  treatment-naïve  patients 
with resectable early stage non-small cell lung cancer (NSCLC). The primary objectives of the study are 
to assess antitumor activity of neoadjuvant treatment based on pathological complete response (pCR) and 
safety.  Innate  is  responsible  for  conducting  the  study  and  shares  study  costs  with  AstraZeneca. 
AstraZeneca supplies clinical trial drugs.

The  first  patient  was  dosed  in  June  2023.  In  October  2023,  Innate  Pharma  presented  at  the  ESMO 
conference  a  trial-in-progress  poster  on  the  MATISSE  study:  "A  Phase  II  multicenter,  open  label,  non-
randomized study of neoadjuvant and adjuvant treatment with IPH5201 and durvalumab in patients with 
resectable, early-stage (II to IIIA) non-small cell lung cancer (MATISSE)." 

d. Partnership

In  October  2018,  Innate  Pharma  and  AstraZeneca  entered  into  a  development  collaboration  and  option 
agreement  for  further  co-development  and  co-commercialization  for  IPH5201.  Following  the  dosing  of 
the first patient on March 9, 2020, in the IPH5201 Phase 1 clinical trial, AstraZeneca made a $5 million 

98

milestone  payment  to  Innate  under  the  companies’  October  2018  multi-product  oncology  development 
collaboration. Innate made a €2.7 million milestone payment to Orega Biotech SAS after the dosing of the 
first patient in the Phase 1 pursuant to Innate’s exclusive licensing agreement (see “Item 10C.—Material 
Contracts”).

In June 2022, the 2018 IPH5201 Option Agreement was amended. Innate received a $5 million milestone 
payment from AstraZeneca upon signature of the amendment and is responsible for conducting a Phase 2 
multicenter,  open  label,  non-randomized  study  of  neoadjuvant  and  adjuvant  treatment  with  IPH5201, 
durvalumab,  and  chemotherapy  in  patients  with  resectable,  early-stage  non-small  cell  lung  cancer 
(NSCLC).  The  "MATISSE"  Study  has  started  and  is  recruiting  patients.  AstraZeneca  and  Innate  will 
share study costs and AstraZeneca will supply clinical trial drugs. Innate made a €0.6 million milestone 
payment to Orega Biotech SAS pursuant to Innate’s exclusive licensing agreement.

IPH5301, an Anti-CD73 Antibody Targeting the Immunosuppressive Adenosine Pathway 

a. Mechanism & Rationale

Targeting  the  pathway  that  metabolizes  adenosine  triphosphate  (ATP)  to  adenosine  in  the  tumor 
microenvironment is an emerging therapeutic strategy to promote antitumor immunity (Di Virgilio et al., 
2018,  Leone  et  al.,  2018,  Vijayan,  2017).  Within  the  tumor  microenvironment,  extracellular  ATP  is 
released  by  dying  cells  and  has  an  immune-stimulatory  activity,  promoting  activation  of  antigen 
presenting cells, and a subsequent immune response (de Andrade Mello et al., 2017; Ghiringhelli et al., 
2009). The extracellular enzyme CD39 hydrolyses ATP into adenosine diphosphate (ADP) and adenosine 
monophosphate  (AMP)  in  the  extracellular  space,  and  CD73  ectonucleotidase  (NT5E,  ecto-5’-
exerts 
nucleotidase) 
immunosuppressive  effects  on  both  the  myeloid  and  lymphoid  compartments  (de  Andrade  Mello  et  al., 
2017).  In  T  cells,  adenosine  inhibits  effector  T  cell  activation,  induces  T  cell  anergy  and  expands  T 
regulatory  cells  (Ehrentraut  et  al.,  2012;  Romio  et  al.,  2011;  Zarek  et  al.,  2008).  Finally,  adenosine 
inhibits NK cell-mediated tumor cell lysis (Beavis et al., 2013). 

(Allard,  2016).  Adenosine 

further  metabolizes  AMP 

adenosine 

to 

The  benefit  of  targeting  CD73  in  oncology  has  been  further  demonstrated  by  results  of  the  COAST 
randomized  Phase  2  study,  where  anti-CD73  oleclumab  in  combination  with  durvalumab  improved 
progression-free  survival  (PFS)  and  objective  response  rate  (ORR)  compared  to  durvalumab  alone  in 
patients with unresectable, Stage III non-small cell lung cancer (NSCLC) (Herbst, JCO, 2022), as well as 
in results from NeoCoast randomized Phase 2 study showing that one cycle of neoadjuvant oleclumab in 
combination  with  durvalumab  improved  MPR  (Major  Pathological  Response)  and  pCR  (pathological 
Complete Response) rates versus durvalumab alone, in stage I-IIIA resectable NSCLC patients (Cascone, 
AACR 2022).

The  Company  is  developing  IPH5301  (anti-CD73)  as  a  potential  anticancer  therapy  for  patients  with 
advanced  or  metastatic  disease  in  selected  solid  tumors.  IPH5301  is  a  monoclonal  antibody  that 
selectively binds to and inhibits the activity of both membrane-bound and soluble human CD73 (NT5E, 
ecto-5’-nucleotidase).

IPH5301  inhibits  CD73-mediated  hydrolysis  of  adenosine  monophosphate  (AMP)  to  adenosine.  CD73 
has  been  shown  to  be  expressed  by  tumor  cells  as  well  as  stromal  cells,  endothelial  cells  and  B  and  T 
lymphocytes  within  the  tumor  microenvironment,  and  it  has  been  shown  to  play  a  significant  role  in 
promoting immunosuppression through the pathway degrading AMP into adenosine. Therefore, inhibition 
of  CD73-mediated  hydrolysis  of  AMP  by  IPH5301  has  the  potential  to  reduce  the  formation  of 
immunosuppressive  adenosine,  thereby  leading  to  increased  antitumor  immunity  across  multiple  tumor 
types, as shown in the figure below.

b.

Indication

In  the  tumor  microenvironment,  CD73  is  expressed  by  tumor  cells  as  well  as  stromal  cells,  endothelial 
cells and B and T lymphocytes (Allard et al., 2017). Inhibition of CD73 enzymatic activity by IPH5301 
has the potential to reduce the formation of immunosuppressive adenosine, thereby leading to increased 
antitumor immunity across multiple tumor types. 

c. Preclinical Development

CD73 immunohistochemistry studies have revealed that in breast, pancreas and ovarian cancers the vast 
majority  of  patients  expressed  CD73  on  either  tumor  or  stromal  cells  (Wang  et  al;  Oncotarget  2017, 
Innate Pharma Internal data). Additionally, high expression of CD73 in tumors has been associated with 
poor prognosis in a variety of cancer types: non-small cell lung cancer, prostate cancer, TNBC, ovarian 
cancer,  colorectal  cancer  and  gastric  cancer  (Inoue  et  al.  2017;  Leclerc  et  al.  2016;  Loi  et  al.  2013; 
Gaudreau et al. 2016; Wu et al. 2016; Lu et al. 2013).  

CD73-deficient mice have been shown to have an increased resistance to the growth of tumors derived 
from  a  variety  of  certain  tumor  cell  lines,  as  well  as  to  metastasis  (Stagg  2011).  These  mice  were  also 
resistant to the induction of fibrosarcomas by the carcinogen 3-methylcholanthrene (MCA), as well as to 
the  continued  growth  of  established  MCA-induced  tumors  (Stagg  2012).  Wild  type  mice  showed 
decreased tumor growth and metastases in some models when administered with an anti-CD73 antibody 
alone (Antonioli, 2016, Antoniolli 2017). The small anti-tumor effect of anti-CD73 antibodies in mouse 
models  was  greatly  enhanced  by  combination  with  checkpoint  inhibition  such  as  PD-1  or  an  adenosine 
receptor antagonist (Allard, 2013; Young, 2016). 

The  Company  published  preclinical  data  further  supporting  the  rationale  of  developing  IPH5301. 
IPH5301 blocked the enzymatic activity of both CD73 expressed at the cell surface and the soluble form 
of  CD73.  IPH5301  was  able  to  efficiently  restore  T  cell  proliferation  inhibited  by  AMP  in  vitro.  In 
addition,  IPH5301  has  been  observed  to  have  a  differentiated  and  superior  activity  compared  to 
benchmark antibodies that are currently in clinical development (Perrot, 2019).

In syngeneic murine tumor-bearing human CD73 knock-in mice, IPH5301 enhanced the antitumor effects 
of  PD-1  blockade,  as  shown  in  the  figure  below.  The  four  graphs  show  changes  in  tumor  volume  over 
time  depending  on  the  type  of  treatment  group,  which  included  a  control  group  (black),  an  IPH5301 

100

(mouse version) group (pink), an anti-mouse PD-1 group (blue) and an PD-1 and IPH5301 combination 
group (green).  

Thus,  IPH5301  could  potentially  exhibit  a  favorable  efficacy  profile  in  patients  with  advanced  or 
metastatic disease in selected solid tumors, including serving as a candidate for combination treatments 
with chemotherapy or immune therapeutic agents.

As further evidence for the negative role of CD73 in anti-tumor response, Loi et al., 2013, examined gene 
expression  data  from  6,000  breast  cancer  patients  and  found  that  high  CD73  expression  was  associated 
with poor prognosis in triple-negative breast cancer (TNBC), as was the association between high CD73 
gene expression and pre-surgery treatment with the standard of care chemotherapy anthracycline. In mice 
inoculated with the syngeneic 4T1.2 breast tumor cell line, a combination of an anti-CD73 antibody and 
doxorubicin (an anthracycline) led to a greater reduction in tumor volume and increase in mouse survival 
than either treatment alone. 

In HER2-positive breast tumors, high CD73 expression was shown to promote resistance to trastuzumab. 
In  addition,  targeting  CD73  was  shown  to  enhance  efficacy  of  treatment  with  anti-HER2  therapy 
(Turcotte,  2017).  On  the  other  hand,  several  chemotherapeutic  agents  including  taxanes,  anthracyclines 
and platinum salts were shown to increase the release of ATP (Martins and Tesniere, 2009); (Martins and 
Wang, 2014). 

All together, these preclinical results indicate that CD73 blockade with IPH5301 has also the potential to 
enhance antitumor activity observed with not only PD1 immunotherapy, but also with chemotherapy and 
trastuzumab.

d. Ongoing Clinical Trial

In December 2021, an investigator-sponsored Phase 1 trial of IPH5301 was initiated by the Institut Paoli-
Calmettes.  CHANCES-IPC  2021-008  (NCT05143970)  is  a  First  In  Human,  Phase  1,  multicenter, 
European study evaluating an anti-CD73, IPH5301, in advanced and/or metastatic cancer. The trial will 
be  conducted  in  two  parts.  The  Part  I-Dose  escalation  aims  to  identify  the  maximum  tolerated  dose 
(MTD)  of  IPH5301  agent  in  monotherapy  and  recommended  Phase  2  dose  (RP2D)  for  future  trials, 
followed  by  a  safety  expansion  study  part  cohort.  In  the  Part  II-Expansion  cohort,  a  total  of  12  HER2+ 
cancer patients, respectively six breast cancer patients and six gastric cancer patients, are planned to be 
enrolled into the next expansion cohort to select a recommended dose of IPH5301 to be administered in 
combination  with  chemotherapy  and  trastuzumab  for  evaluation  in  future  trials  with  selected  advanced 
solid tumors. In March 2022, The Institut Paoli Calmettes announced that the first patient had been dosed. 
In December 2022, a "Trial in Progress" poster was presented by the Institut Paoli Calmettes at ESMO-IO 
2022 congress (Goncalvez, ESMO-IO 2022, Poster 199, abstract 290). This trial is ongoing.

ANKET® Platform

a. General Overview

Multi-specific  monoclonal  antibodies,  or  multi-specifics,  are  antibody-derived  formats  that  can 
simultaneously  bind  to  two  or  more  different  types  of  molecules.  A  number  of  studies  of  bispecific 
antibodies  are  currently  underway,  such  as  those  assessing  the  safety  and  efficacy  of  bispecific  T  cell 
engagers, such as BiTEs, which engage T cells via the antigen receptor on one side of the bispecific T cell 
engager,  and  a  tumor  antigen  on  the  other  side  of  the  BiTE.  These  molecules  have  demonstrated  the 
ability to reduce or slow the growth of tumors in cancer patients, but they also carry a significant toxicity 
risk.  This  toxicity  risk  occurs  by  engaging  all  T  cells,  irrespective  of  their  specificity  and  development 
status, potentially leading to an overt production of cytokines by these T cells, referred to as a cytokine 
storm. In parallel, bispecific killer cell engagers (BiKEs) that engage CD16 receptors found on NK cells, 
and tri-specific killer cell engagers (TriKEs) that engage CD16 receptors and contain IL-15, a cytokine 
that promotes NK cell activation and survival, have also been developed to target antigens expressed on 
solid tumors. BiKEs and TriKEs can be effective both in vitro and in vivo in preclinical models. These 
multi-specific molecules that engage NK cells could reduce the risks associated with toxicity, as NK cell 
counts represent only approximately 10% of T cell counts, thereby potentially limiting the likelihood of 
inducing  a  cytokine  storm.  However,  it  remains  unclear  whether  these  multifunctional  CD16  engager 
antibodies can activate NK cells in solid tumors since they often express low levels of CD16. 
ANKET® (Antibody-based NK cell Engager Therapeutics) is Innate’s proprietary platform for developing 
next-generation, multi-specific NK cell engagers to treat certain types of cancer.

This  versatile,  fit-for-purpose  technology  is  creating  an  entirely  new  class  of  molecules  to  induce 
synthetic immunity against cancer. It leverages the advantages of harnessing NK cell effector functions 
against cancer cells and also provides proliferation and activation signals targeted to NK cells.
Innate's latest innovation, the tetra-specific ANKET® molecule, is the first NK cell engager technology to 
engage  activating  receptors  (NKp46  and  CD16),  a  tumor  antigen  and  an  interleukin-2  receptor  (via  an 

102

IL-2  variant,  IL-2v)  via  a  single  molecule.  This  innovation  is  built  on  its  existing  tri-specific  NK  cell 
engager technology, which has demonstrated potent NK cell activation, cytotoxicity and efficient control 
of tumor growth in preclinical models.

Because NKp46 is expressed on all NK cells and conserved on tumor infiltrating NK cells, and NK cells 
are not expected to produce a cytokine storm, ANKET® molecules may overcome the limitations of both 
ADCC-inducing antibodies and T cell engagers.

IPH6101/SAR'579, a CD123-targeting NK Cell Engager

a. Mechanism

IPH6101/SAR443579 is the first trifunctional anti-CD123 NK cell engager NKp46/CD16 using Innate’s 
proprietary  multi-specific  antibody  format  ANKET®.  It  has  shown  anti-tumor  activity  in  preclinical 
models, including supporting pharmacokinetic/pharmacodynamic (PK/PD) and safety data in non-human 
primate studies, leading to its selection as a drug candidate for development. It is part of the Sanofi 2016 
research  collaboration  and  licensing  agreement,  under  which  the  companies  collaborate  on  the 
development  of  innovative  multi-specific  antibody  formats  engaging  NK  cells  through  the  activating 
receptors  NKp46  and  CD16  to  kill  tumor  cells.  Several  NK  cell  therapies  have  been  shown  to  induce 
antitumor  responses,  without  the  complications  frequently  associated  with  T  cell  therapies,  such  as 
cytokine release syndrome (CRS) or neurotoxicity.

b.

Indication and Rationale

Acute myeloid leukemia (AML) is the most common acute leukemia in adults, mostly affecting elderly 
patients, with a median age at diagnosis of 65-70 years. AML is a heterogeneous cancer characterized by 
the clonal expansion of myeloid precursors in the bone marrow and peripheral blood. Despite significant 
progress in the care of AML patients in the past decade, there is still a clear unmet medical need in AML, 
as up to 50% of patients relapse after initial chemotherapy, and the prognosis for older patients remains 
poor.

Cytotoxic  antibodies  targeting  CD123  displayed  limited  antileukemic  activity  in  several  clinical  trials, 
even  when  tested  in  the  form  of  Fc-engineered  antibodies  designed  specifically  to  increase  antibody-
dependent  cell  cytotoxicity  (ADCC).  By  contrast,  T  cell  engager  molecules  and  CAR-T  cell  therapies 
have  some  clinical  efficacy,  but  are  also  highly  toxic,  confirming  the  need  for  alternative  targeted 
approaches for the treatment of AML. NK cell-based therapies may provide new treatment perspectives 
and a safer alternative for targeting tumor cells in this context.

103

c. Preclinical Development

In its preclinical studies, Innate and Sanofi investigated whether NKp46-based NKCE technology could 
provide more effective antitumor activity than regular IgG antibodies for AML treatment by generating a 
NKCE  molecule  targeting  CD123.  Innate  and  Sanofi  evaluated  the  ex  vivo  antitumor  activity  of  this 
molecule,  comparing  it  with  a  regular  IgG1  antibody  derived  from  clone  7G3  (CD123-IgG1+)  with  an 
engineered Fc domain for enhanced ADCC.

The  anti-CD123  antibody-mediated  killing  of  primary  blasts  from  AML  patients  (AML#1  to  AML#4) 
was evaluated ex vivo with NK cells from healthy donors as effectors. The anti-CD123 antibody (CD123-
IgG1+) mediated the killing of blasts from half the patient samples (AML#1 and AML#2) but was barely 
active  against  blasts  from  the  other  half  of  the  primary  samples  (AML#3  and  AML#4).  The  patient 
samples  could  therefore  be  separated  into  two  distinct  groups:  CD123-IgG1+-responders  and  CD123-
IgG1+-non-responders.
Innate  and  Sanofi  observed  that  trifunctional  CD123-ANKET®  displayed  killing  activity  against  all 
primary malignant AML cells, promoting significant antitumor activity in CD123-IgG1+-non-responders 
samples  from  AML  patients  against  which  the  regular  anti-CD123  cytotoxic  antibody  was  completely 
inactive.

The  minimal  level  of  pro-inflammatory  cytokine  release  following  the  treatment  of  human  peripheral 
blood mononuclear cells (PBMCs) with NKCE in vitro (data not shown) was further confirmed in vivo, in 
dedicated pharmacokinetic (PK), pharmacodynamic (PD) and toxicology studies performed in non-human 
primates (NHPs).

Innate and Sanofi evaluated the PK/PD of CD123-NKCE administered by a single one-hour i.v. infusion 
of a high (3 mg/kg) or low (3 µg/kg) doses in male cynomolgus monkeys (two animals each for the 3 mg/
kg  and  3  µg/kg  doses).  Treatment  with  CD123-NKCE  promoted  a  sustained  and  complete  depletion  of 
CD123+ cells in the blood of all monkeys, for more than 10 days, at both the 3 mg/kg and 3 µg/kg doses, 
with only very small amounts (< 50 pg/mL) of the pro-inflammatory cytokines IL-6 and IL-10 released 
without any associated clinical signs.

104

d. Ongoing Clinical Trial

IPH6101/SAR443579 is currently being evaluated in a Phase 1/2 clinical trial (NCT05086315) in patients 
with relapsed or refractory acute myeloid leukemia (R/R AML), B-cell acute lymphoblastic leukemia (B-
ALL) or high risk-myelodysplastic syndrome (HR-MDS). 

The purpose of the dose escalation and dose expansion study, which is sponsored by Sanofi, is to evaluate 
the  safety,  pharmacokinetics,  pharmacodynamics  and  initial  clinical  activity  of  IPH6101/SAR443579, 
Innate’s lead ANKET® asset, in various CD123-expressing hematological malignancies.

Innate Pharma announced that the first patient was dosed on December 16, 2021.

In  June  2023,  safety  and  preliminary  efficacy  were  presented  during  an  oral  presentation  at  the 
ASCO Meeting. Preliminary data showed SAR443579 / IPH6101 was well tolerated and induced 
three complete responses in the eight patients at 1 mg/kg as the highest dose. In addition, Innate 
Pharma  shared  Sanofi’s  news  that  the  FDA  has  granted  Fast  Track  Designation  for  SAR’579  / 
IPH6101 for the treatment of hematological malignancies. 

In October 2023,  a preliminary Pharmacokinetics (PK) and Pharmacodynamic (PD) Analysis of 
the CD123 NK Cell Engager SAR’579/IPH6101 in patients with relapsed or refractory AML, B-
ALL or HR-MDS was presented at the ESMO congress. 

In December 2023, updated efficacy and safety results were shared in a poster presentation at the 
ASH Annual Meeting. Abstract details included:

• As of July 5, 2023, 43 patients (42 R/R AML and one HR-MDS) across eight dose levels 
at 10 – 6000 μg/kg/dose were included. Patients had received a median of 2.0 (1.0 – 10.0) 
prior lines of treatment with 13 patients (30.2%) reporting prior hematopoiectic stem cell 
transplantation and 36 patients (83.7%) with prior exposure to venetoclax. 

•

In dose levels with a highest dose of 1000 μg/kg QW, 5 out of 15 (33.3%) AML patients 
achieved a complete remission, or CR, (4 CRs and 1 CR with incomplete hematological 
recovery) as of the cut-off date. 

105

• Data  from  preliminary  pharmacokinetics  /  pharmacodynamic  and  in  vitro  mechanistic 

analyses studying dose-response relations were also presented. 

•

SAR443579  was  well  tolerated  up  to  doses  of  6000  μg/kg  QW  with  observed  clinical 
benefit in patients with R/R AML. The results are consistent with the predicted favorable 
safety profile.

Proprietary ANKET®

IPH6501, a CD20-targeting tetra-specific NK Cell Engager

a. Mechanism

The  IPH6501  program  is  developing  a  CD20-targeting  tetra-specific  Antibody-based  NK  cell  Engager 
Therapeutics  (ANKET®).  CD20  is  an  antigen  expressed  by  a  number  of  B  cell  malignancies,  and  its 
targeting  by  therapeutic  antibodies  has  shown  efficacy  to  treat  the  patients  although  a  number  of  the 
tumors develop resistance and relapse. Compared to a classical IgG1-based antibody which engages Fc 
receptors  and  a  tumor  antigen,  IPH6501  co-engages  on  one  hand  NKp46  and  Fc  receptors,  as  well  as 
CD122 subunit of the IL-2 receptor (but not CD25 subunit), and on the other hand CD20 as a targeted 
antigen  on  malignant  B  cells,  leading  to  potent  NK  cell  activation,  cytotoxicity  and  control  of  tumor 
growth. 

IPH6501  was  designed  to  induce  NK  cell  mediated-cytotoxicity  and  cytokine  secretion  by  co-engaging 
CD16a and NKp46. Only the binding of IPH6501 to CD20, bridging the NK cells to the target cells, was 
able  to  trigger  the  cytotoxic  activity  of  NK  cells.  IPH6501  is  thus  a  promising  biologic  designed  to 
harness the anti-tumor functions of NK cells in CD20+ B cell malignancies. 

Moreover, the IL-2R binding element incorporated in IPH6501 is an IL-2 variant (IL-2v) designed with 
point mutations that abolish binding to the IL-2R-α chain (CD25), with the goal of limiting toxicity and 
interaction with Tregs.  IL-2v incorporated into IPH6501 is directed towards NK cells through the binding 
with high affinity to NKp46 and CD16a, providing its ability to interact with IL-2R preferentially on NK 
cells and to promote their activation and proliferation at pM doses. 

b.

Indication and Rationale

IPH6501  is  being  developed  in  patients  with  relapsed  or  refractory  (R/R)  CD20+  B-cell  non-Hodgkin's 
lymphomas (NHL). 

NHL is the most prevalent hematological malignancy, accounting for 4% of all new cancer cases and 3% 
of cancer-related deaths in the United States (Howlader 2020a, Howlader 2020b). For 2021, estimates for 
the  United  States  include  81,560  new  cases  and  20,720  deaths  from  NHL  (American  Cancer  Society 
2021a, American Cancer Society 2021b). In 2020, Europe had 122,979 new cases of NHL reported, and 

107

49,684  deaths  were  attributable  to  NHL  (World  Health  Organization  (WHO)  2020).  The  emergence  of 
relapsed  refractory  (r/r)  disease  among  B-cell  malignancies  with  curtailed  sustained  responses  to 
treatment  and  unattained  long-term  survivals  has  created  a  significant  unmet  need  (National 
Comprehensive Cancer Network (NCCN) 2021a).   

CD20 is expressed by >90% of B-cell non-Hodgkin's lymphomas (NHL). Several generations of CD20-
targeting monoclonal antibodies including rituximab, ofatumumab, and obinutuzumab have been widely 
used for B-cell malignancy therapies. Despite the recent approvals of novel CD20-targeting agents, new 
alternatives  and  strategies  are  still  required  for  patients,  which  are  relapsing  or  refractory  after  several 
lines of treatment.  High circulating NK cell numbers have been associated with better clinical responses 
to  anti-CD20-targeting  monoclonal  antibodies,  supporting  the  role  of  NK  cells  in  efficacy  of  these 
treatments.

c. Preclinical Development

IPH6501  preclinical  activity  was  explored  both  in  vitro  and  in  vivo.  In  vitro  studies  established  that 
IPH6501´s  main  modes  of  action  were  NK  cell  proliferation  and  antibody-dependent  cell  cytotoxicity 
(ADCC) against CD20-expressing cells.

•

In vitro 

Non-saturating doses of IPH6501 on NK cells and on CD20+ cells were sufficient to promote maximal 
killing activity. Furthermore, IPH6501 promoted NK cell cytotoxicity against tumor cells expressing very 
low  levels  of  CD20.  IPH6501  also  demonstrated  superiority  to  control  tumor  cell  growth  in  vitro,  as 
compared  to  the  CD20-targeting  clinical  benchmark  antibodies  rituximab  and  the  Fc-optimized 
obinutuzumab. 
IPH6501 alone without NK cells did not induce direct killing of CD20+ cells. Culturing human purified 
NK cells with CD20+ B-lymphoma cell lines and IPH6501 induced the specific lysis of tumoral CD20+ 
cells.  Alternatively,  culturing  human  PBMCs  with  IPH6501  induced  the  specific  depletion  of  normal 
CD20+  B  lymphocytes  without  affecting  other  lymphocyte  population  numbers,  as  well  as  cytokine 
production  in  line  with  NK  cell  activation.  Incubation  of  human  PBMC  with  IPH6501  induced  a 
preferential NK cell proliferation that occurred at lower doses as compared to the proliferating effect of 
IPH6501 on other CD8+ or CD4+ T lymphocytes (expressing the IL-2R).

•

In vivo 

In  vivo  treatment  with  a  mouse  surrogate  of  IPH6501  induced  peripheral  NK  cell  proliferation  and 
activation, and demonstrated potent antitumor efficacy in a xenograft mouse model using the aggressive 
human B-lymphoma CD20+ RAJI cell line engrafted subcutaneously. Surrogate moIPH6501 also showed 

108

a dose dependent and significant control of tumor growth in a model of CD20-expressing B16F10 cells 
injected intravenously (IV) in immunocompetent mice, as shown in figure below. 

Updated  preclinical  data  were  presented  at  the  European  Hematology  Association  (EHA)  congress  in 
June  2023,  including  experiments  on  non-human  primates  and  samples  from  R/R  B-NHL  patients.  In 
preclinical  settings,  IPH6501  was  shown  to  induce  NK  cell  proliferation  and  to  trigger  high  NK  cell 
cytoxicity against CD20+ target cells in in vitro assays, in ex vivo assays with relapse/refractory (R/R) B-
NHL patient samples who received at least one prior treatment, as well as in in vivo studies in non-human 
primates. A surrogate of IPH6501 mediated a potent anti-tumor activity in vivo in CD20+ tumor models 
in mice. In addition, in ex vivo assays with R/R B-NHL patient samples, IPH6501 was shown to be more 
efficient than a T cell engager targeting CD20.

• Non-human primates 

In  non-human  primates,  a  well-tolerated  dose  of  IPH6501  resulted  in  NK  cell  expansion,  with  minimal 
increase in systemic cytokine levels, and to the depletion of CD20+ B cells in circulation and lymphoid 
tissues.

• Analysis from samples from R/R B-NHL patients

Flow cytometric analysis of samples from R/R B-NHL patients revealed that NK cell numbers in blood 
were  within  normal  range  values,  and  NKp46  expression  was  maintained  in  blood  and  tumor-involved 
lymph nodes. Of note, in contrast to NKp46, cell surface expression of CD16 was down-regulated on NK 
cells in B-NHL patient’s lymph nodes, suggesting a potential therapeutic advantage of targeting NKp46 
with  IPH6501  in  B-NHL  compared  with  classical  monoclonal  antibodies.  IPH6501  stimulated  NK  cell 

109

 
  
proliferation  andCD20+  cell  depletion  ex  vivo  in  PBMC  samples  from  R/R  B-NHL  patients,  which 
compared favourably with acontrol CD3xCD20 T cell engager.

IPH6501  is  a  first-in-class  CD20-targeting  tetra-specific  NK  cell  engager  designed  to  promote  NK  cell 
proliferation and specific cytotoxicity against CD20+ cells. IPH6501 is thus a promising biologic designed 
to harness the anti-tumor functions of NK cells in CD20+ B cell malignancies. 

d. Clinical Trial

An international, first-in-human, multicenter, open-label Phase 1/2 study will evaluate the safety profile, 
tolerability of IPH6501, and determine the recommended Phase 2 dose (RP2D) for patients with B-Cell 
non-Hodgkin lymphoma. The Company received a Study May Proceed Letter from FDA in July 2023.

On March 6, 2024, the Company announced that the first patient was dosed in its Phase 1/2 multicenter 
trial (NCT06088654), investigating the safety and tolerability of IPH6501 in patients with Relapsed and/
or  Refractory  CD20-expressing  B-cell  non-Hodgkin’s  lymphoma.  The  study  is  ongoing  and  planned  to 
enroll up to 184 patients. 

Antibody Drug Conjugates

a. Proprietary

To further our R&D program, the Company continues to develop different approaches for the treatment of 
cancer utilizing its antibody engineering capabilities to deliver novel assets, with its innovative ANKET® 
platform  and  continuing  to  explore  Antibody  Drug  Conjugates  (ADC)  formats.  The  Company  has  a 
robust  pipeline  of  additional  preclinical  product  candidates.  Its  additional  disclosed  preclinical  pipeline 
includes :

–

IPH45 is Innate’s proprietary pre-IND anti-Nectin-4 targeting antibody drug conjugate including 
a Topoisomerase I inhibitor payload. IPH45 is progressing towards the clinic with IND targeted 
in 2024.

–

IPH43, an anti-MICA/B ADC.

Innate will share first preclinical data with IPH45 in an oral presentation at the American Association for 
Cancer Research (AACR) 2024.

b. Partnered

Innate announced in April 2023 that it granted Takeda exclusive worldwide rights to research and develop 
ADC  using  a  panel  of  selected  Innate  antibodies  against  an  undisclosed  target,  with  a  primary  focus  in 
Celiac disease.

110

Takeda  will  be  responsible  for  the  future  development,  manufacture  and  commercialization  of  any 
potential products developed using the licensed antibodies.

Under  the  terms  of  the  license  agreement,  Innate  has  received  an  upfront  payment  of  $5  million  and  is 
eligible to receive up to $410 million in future development, regulatory and commercial milestones if all 
milestones  are  achieved  during  the  term  of  the  agreement,  plus  royalties  on  potential  net  sales  of  any 
commercial product resulting from the license.

Next Step 

Competition 

The biotechnology and pharmaceutical industry, and notably the cancer field, is characterized by rapidly 
advancing technologies, products protected by intellectual property rights and intense competition and is 
subject  to  significant  and  rapid  changes  as  researchers  learn  more  about  diseases  and  develop  new 
technologies  and  treatments.  While  the  Company  believes  that  its  technology,  knowledge,  experience, 
collaborations  and  scientific  resources  provide  Innate  with  competitive  advantages,  the  Company  faces 
potential  competition  from  many  different  sources, 
including  major  pharmaceutical,  specialty 
pharmaceutical  and  biotechnology  companies,  academic  institutions,  governmental  agencies  and  public 
and private research institutions. Any approved product that Innate Pharma commercializes will compete 
with existing therapies and new therapies that may become available in the future.

A large number of companies are developing or marketing treatments for cancer, including many major 
pharmaceutical  and  biotechnology  companies.  Many  of  their  competitors  have  significantly  greater 
experience,  personnel  and  resources  as  they  relate  to  research,  drug  development,  manufacturing  and 
marketing.  In  particular,  large  pharmaceutical  laboratories  have  substantially  more  experience  than  the 
Company  does  in  conducting  clinical  trials  and  obtaining  regulatory  authorizations.  Mergers  and 
acquisitions  in  the  pharmaceutical,  biotechnology  and  diagnostic  industries  may  result  in  even  more 
resources  being  concentrated  among  a  smaller  number  of  its  competitors.  Smaller  or  early-stage 
companies may also prove to be significant competitors, particularly through collaborative arrangements 
with large and established companies. These competitors are also likely to compete with Innate to recruit 
and  retain  top  qualified  scientific  and  management  personnel,  acquire  rights  for  promising  product 
candidates and technologies, establish clinical trial sites and patient registration for clinical trials, acquire 

111

technologies complementary to, or necessary for, its programs and enter into collaborations with potential 
partners who have access to innovative technologies.

Innate's  commercial  opportunity  could  be  reduced  or  eliminated  if  its  competitors  develop  and 
commercialize products that are more effective, have a better safety profile, are more convenient, have a 
broader label, have more robust intellectual property protection or are less expensive than any products 
that  the  Company  may  develop.  Its  competitors  also  may  obtain  regulatory  approval  for  their  products 
more  rapidly  than  the  Company  may  obtain  approval  for  its  products,  which  could  result  in  its 
competitors  establishing  a  strong  market  position  before  the  Company  is  able  to  enter  the  market.  In 
addition,  its  competitors  could  be  more  efficient  in  manufacturing  or  more  effective  in  marketing  their 
own products than the Company or its partners may be in the future.

With respect to its lead product candidate, lacutamab, a monoclonal antibody product candidate targeting 
KIR3DL2,  the  Company  is  aware  of  several  pharmaceutical  companies  marketing  and  developing 
products for the treatment of patients with CTCL, including MF and Sézary syndrome, and PTCL. The 
latest  drugs  approved  by  the  FDA  for  CTCL  are:  Adcetris  (brentuximab  vedotin),  marketed  by  Seattle 
Genetics  and  approved  in  combination  with  chemotherapy  for  treatment  of  patients  with  primary 
cutaneous  anaplastic  large  cell  lymphoma  (pcALCL)  or  CD30-expressing  MF  who  have  received  prior 
systemic  therapy,  and  Poteligeo  (mogamulizumab),  marketed  by  Kyowa  Kirin  and  approved  for  the 
treatment  of  adult  patients  with  R/R  MF  or  Sézary  syndrome  after  at  least  one  prior  systemic  therapy. 
Zolinza (vorinostat) is the only drug approved by the FDA for CTCL patients after two prior failures. In 
the  second  line  setting  of  PTCL,  Beleodaq  (belinostat),  Folotyn  (pralatrexate)  and  Istodax  (romidepsin) 
have all been approved by the FDA; however, none of these treatments have been approved by the EMA. 

With respect to monalizumab, a novel dual-targeting checkpoint inhibitor, other anti-NKG2A have started 
to  be  assessed  in  clinical  trials,  and  several  pharmaceutical  companies  are  marketing  and  developing 
treatments  for  either  NSCLC.  Currently  two  ongoing  clinical  trials  are  assessing  other  anti-NKG2A 
molecules. A Phase 1/2 is assessing BMS-986315 (Bristol-Myers Squibb) monotherapy or in combination 
with  nivolumab  or  cetuximab  in  patients  with  solid  tumors.  A  Phase  1  study  is  assessing  S095029 
(Servier)  monotherapy  or  in  combination  with  an  anti-PD-1  in  patients  with  solid  tumors  with  dose 
expansion  cohorts  that  add  an  anti-HER2  or  anti-EGFR  to  the  doublet.  A  Phase  1  study  is  evaluating 
BRY805 (BioRay Pharmaceutical Co.) as monotherapy in patients with solid tumours. Exelis and Invenra 
are collaborating to develop a bispecific targeting PD-L1 and NKG2A  which is in the preclinical setting. 

There  are  also  several  pharmaceutical  and  biotechnology  companies  that  are  focused  on  the  tumor 
microenvironment, including the complement and the adenosine pathways. Many companies are active in 
the adenosine pathway, targeting CD73, CD39 or the adenosine receptors. For example, AstraZeneca and 
I-Mab Biopharma U.S. Limited each have anti-CD73 product candidates in Phase 2 clinical development, 
and several other biotechnology companies are active in the adenosine pathway area, including Trishula 
Therapeutics, Inc., Novartis Pharmaceuticals, Gilead Sciences, Inc. and  Arcus Biosciences Inc.

NK  cells  have  been  increasingly  researched  and  the  Company  is  aware  of  many  companies  activating 
and  /or  harnessing  NK  cells  to  target  and  kill  cancer  cells  through  different  approaches  such  as  cell 
therapies  (for  example,  Fate  Therapeutics,  Inc.  and  NKarta,  Inc.)  and  multi-specifics  (for  example, 
Affimed N.V. and Dragonfly Therapeutics, Inc.).

Intellectual Property 

Commercial  success  of  the  Company  depends  in  part  on  obtaining  and  maintaining  patent,  trade  secret 
and  other  intellectual  property  and  proprietary  protection  of  its  technology,  current  and  future  products 
and product candidates and methods used to develop and manufacture them. The Company cannot be sure 

112

that  patents  will  be  granted  with  respect  to  any  of  its  pending  patent  applications  or  to  any  patent 
applications filed by Innate in the future, nor can the Company be sure that any of its existing patents or 
any patents that may be granted to Innate in the future will be sufficient to protect its technology or will 
not  be  challenged,  invalidated  or  circumvented.  Its  success  also  depends  on  its  ability  to  operate  its 
business  without  infringing,  misappropriating  or  otherwise  violating  any  patents  and  other  intellectual 
property or proprietary rights of third parties. 

The  Company  relies,  in  some  circumstances,  on  trade  secrets  to  protect  its  technology.  However,  trade 
secrets  can  be  difficult  to  protect.  The  Company  seeks  to  protect  its  trade  secrets,  in  part,  by 
confidentiality  agreements  with  its  employees,  consultants,  scientific  advisors  and  contractors.  These 
agreements may not provide meaningful protection or may be breached, and the Company may not have 
an  adequate  remedy  for  any  such  breach.  The  Company  also  seeks  to  preserve  the  integrity  and 
confidentiality of its data and trade secrets by maintaining physical security of its premises and physical 
and  electronic  security  of  its  information  technology  systems.  Notwithstanding  these  measures,  these 
agreements  and  systems  may  be  breached,  and  the  Company  may  not  have  adequate  remedies  for  any 
such breach. In addition, its trade secrets may otherwise become known or be independently discovered 
by  competitors  or  misused  by  collaborators  to  whom  the  Company  discloses  such  information.  Despite 
measures taken to protect its intellectual property, unauthorized parties may attempt to copy aspects of its 
products or drug candidates or obtain or use information that the Company regards as proprietary. As a 
result, the Company may be unable to meaningfully protect its trade secrets and proprietary information. 
To the extent that its employees, consultants, contractors or partners use intellectual property owned by 
others  in  their  work  for  us,  disputes  may  arise  as  to  the  rights  in  related  or  resulting  know-how  and 
inventions.  For  more  information  regarding  the  risks  related  to  intellectual  property,  please  see  “Risk 
Factors—Risks Related to Intellectual Property Rights.”

Patents 

The  Company  files  patent  applications  to  protect  its  product  candidates,  technical  processes  and  the 
processes used to prepare its product candidates, the compounds or molecules contained in these product 
candidates and medical treatment methods. The Company also licenses rights to patents owned by third 
parties, academic partners or other companies in its field.

any potential patent term extension. 

113

IPH5201/Anti-CD39 

As of December 31, 2023, the principal intellectual property rights related to IPH5201 are co-owned by 
Innate  together  with  Orega  Biotech,  and  include  U.S.  patent  No.  11,377,503,  one  European  patent 
application, and other patent applications in certain other countries. These patents and patent applications 
are directed to the composition of matter of IPH5201, and such have, and any patents that issue from such 
patent application would have, a statutory expiration date in 2039, not including patent term adjustment or 
any potential patent term extension. 

IPH5301/Anti-CD73

As of December 31, 2023, the principal intellectual property rights related to IPH5301 are solely owned 
by  us,  and  include  one  U.S.  non-provisional  patent  application,  one  European  patent  application,  and 
other patent applications in certain other countries. If a patent directed to IPH5301 issues from such U.S. 
patent application, it would have a statutory expiration date in 2040, not including patent term adjustment 
or any potential patent term extension. 

IPH6501

As of December 31, 2023, the principal intellectual property rights related to IPH6501 are solely owned 
by  us,  and  include  one  U.S.  non-provisional  patent  application,  one  European  patent  application,  and 
other patent applications in certain other countries. If a patent directed to IPH6501 issues from such U.S. 
patent application, it would have a statutory expiration date in 2042, not including patent term adjustment 
or any potential patent term extension.

The term of individual patents depends upon the legal term of patents in the countries in which they are 
obtained.  In  most  countries,  including  the  United  States,  the  patent  term  is  20  years  from  the  earliest 
claimed  filing  date  of  a  non-provisional  patent  application  or  its  foreign  equivalent  in  the  applicable 
country.  In  the  United  States,  a  patent’s  term  may,  in  certain  cases,  be  lengthened  by  patent  term 
adjustment,  which  compensates  a  patentee  for  administrative  delays  by  the  USPTO  in  examining  and 
granting a patent, or may be shortened if a patent is terminally disclaimed over a commonly owned patent 
or a patent naming a common inventor and having an earlier expiration date. In the United States, a patent 
may also be eligible for limited patent term extension under the Drug Price Competition and Patent Term 
Restoration  Act  of  1984,  or  Hatch-Waxman  Amendments.  The  Hatch-Waxman  Amendments  permit  a 
patent extension term of up to five years as compensation for patent term lost during the FDA regulatory 
review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 
years from the date of product approval, only one patent applicable to each regulatory review period may 
be  extended  and  only  those  claims  covering  the  approved  drug,  a  method  for  using  it,  or  a  method  for 
manufacturing it may be extended.  

Trademarks 

The  Company  owns  the  mark  INNATE  PHARMA  in  the  United  States,  Australia  and  Europe  (EU 
community  trademark),  and  INNATE  in  Europe  (EU  community  trademark).  The  Company  also  owns 
registrations  for  the  mark  ANKET®  respectively  in  the  United  States  and  Europe  (EU  community 
trademark), the marks LONKIRLO and KIRTAMSY in France.

Regulation

Research and development work, preclinical tests, clinical studies, facilities, and the manufacture and sale 
of  its  products  are  and  will  continue  to  be  subject  to  the  complex  legislative  and  regulatory  provisions 
implemented by the various competent authorities in Europe, the United States and other countries. The 
EMA,  FDA  and  the  various  national  regulatory  authorities  impose  considerable  constraints  on  the 
development, manufacture and sale of products that the Company develops and clinical trials it conducts. 
In  case  of  non-compliance  with  these  laws  or  regulations,  the  regulatory  authorities  may  impose  fines, 
seize  or  withdraw  products  from  the  market  or  even  partially  or  totally  suspend  their  production.  They 
may  also  revoke  previously  granted  marketing  authorizations  and  reject  applications  seeking 
authorization.  These  legal  and  regulatory  constraints  are  important  in  considering  whether  an 
investigational  product  can  ultimately  become  an  approved,  commercialized  drug,  as  well  as  for 
recognizing the time and investments necessary for such development. 

Although there are differences from one country to another, the development of therapeutic products for 
human  use  is  subject  to  similar  procedures  and  companies  must  comply  with  the  same  types  of 
regulations in all ICH countries (countries that are part of the International Council for Harmonisation of 
Technical  Requirements  for  Registration  of  Pharmaceuticals  for  Human  Use).  In  order  to  obtain 
marketing authorization for a product, proof of its efficacy and safety should be provided by the applicant, 
along  with  detailed  information  on  its  composition  and  manufacturing  process.  This  entails  significant 
pharmaceutical  and  preclinical  developments,  clinical  trials  and  laboratory  tests.  The  development  of  a 
new drug from basic research to commercial marketing generally comprises five steps: (i) research, (ii) 
preclinical trials, (iii) clinical trials in humans, (iv) marketing authorization and (v) marketing. 

Preclinical studies 

Preclinical studies include laboratory evaluation of the purity and stability of the manufactured substance 
or active pharmaceutical ingredient and the formulated product, as well as in vitro and animal studies to 
assess  the  safety  and  activity  of  the  product  candidate  for  initial  testing  in  humans  and  to  establish  a 
rationale  for  therapeutic  use.  The  conduct  of  preclinical  studies  is  subject  to  national  regulations  and 
requirements, including Good Laboratory Practices (GLP) regulations. The results of the preclinical tests, 
together with manufacturing information, analytical data, any available clinical data or literature and plans 
for clinical studies, among other things, are submitted to the applicable regulatory agency in connection 
with the application to begin human testing. Some long-term preclinical testing, such as animal tests of 
reproductive  adverse  events  and  carcinogenicity,  and  long-term  toxicity  studies,  may  continue  after 
submission of the application. 

Regulation of clinical trials 

In humans, clinical trials are usually carried out in three Phases that are generally sequential, but under 
certain  circumstances  Phases  of  trials  can  overlap  or  even  be  skipped,  following  a  specific  review  and 
determination  by  regulatory  agencies.  Clinical  trials  are  sometimes  necessary  or  required  by  regulatory 
authorities  after  marketing  authorization  to  explain  certain  side-effects,  investigate  a  specific 
pharmacological  effect  or  obtain  more  accurate  or  additional  data.  Additional  trials  are  also  commonly 
conducted to explore new indications. Regulatory authorization and ethics approvals are needed to carry 
out  clinical  trials.  The  regulatory  authorities  may  put  on  clinical  hold,  block,  suspend  or  require 
significant modifications to the clinical study protocols submitted by companies seeking to test products, 
including the imposition of clinical holds before or after a clinical trial has commenced. 

115

Clinical trial authorization in the European Union 

In the European Union, clinical trials are governed by the Clinical Trials Regulation (EU) No 536/2014 
(CTR), which entered into application on January 31, 2022, repealing and replacing the former Clinical 
Trials Directive 2001/20 (CTD) and related national implementing legislation of EU Member States.  

The  CTR  applies  to  interventional  clinical  trials  on  medicinal  products  and  to  clinical  trials  authorized 
under the CTD with a three-year transition period from the CTR that has come into operation. As from 
January 31, 2023, all new clinical trial applications are registered pursuant to the CTR. Trials approved 
under  the  CTD  before  January  30,  2023  can  continue  to  be  regulated  under  the  CTD  until  January  30, 
2025.

The CTR allows better consistency throughout EU Member States: 

•

•

Single  submission  of  the  clinical  trial  application  dossier  through  the  EU  Clinical  Trials 
Information System (Article 5) including a common part assessed jointly by all participating 
EU Member States, and a national part covering the ethical and operational aspects of the trial 
assessed by each EU Member State independently. 

A clinical trial authorization issued in the form of a single decision.

The CTR applies in the Member States without the requirement for separate implementing legislation by 
each Member State, but some of the existing laws of the Member States applicable at a national level will 
continue to apply.  

This regulation is intended to increase transparency of authorized clinical trials in the European Union: 
the EU Clinical Trials Information System serves as the source of public information, without prejudice 
of  personal  data  protection,  commercially  confidential  information  protection,  and  protection  of 
confidential  communication  and  trial  supervision  between  Member  States.  Public  information  includes 
clinical trial authorization information, protocol data, and a summary of the results 12 months after the 
end of the trial (or six months in case of pediatric clinical trials).  

Clinical trial authorization in the United States 

In the United States, an Investigational New Drug (IND) application must be submitted to the FDA and 
accepted before clinical trials can start on humans. An IND is an exemption from the Federal Food, Drug, 
and  Cosmetic  Act  (FDCA)  that  allows  an  unapproved  product  candidate  to  be  shipped  in  interstate 
commerce for use in an investigational clinical trial and a request for FDA authorization to administer an 
investigational  product  to  humans.  This  application  contains  early  research  data  as  well  as  the 
pharmaceutical dossier, preclinical and clinical data (if any) and includes the clinical protocol. If there is 
no objection from the FDA, the IND application becomes valid 30 days after it is received by the FDA. 
This  waiting  period  is  designed  to  allow  the  FDA  to  review  the  IND  to  determine  whether  human 
research subjects will be exposed to unreasonable health risks. At any time during or subsequent to this 
30-day period, the FDA may request the suspension or clinical hold of clinical trials, whether such trials 
are planned or in progress, and may request additional information. This temporary suspension (clinical 
hold) continues until the FDA receives the information it has requested. 

In addition to the foregoing IND requirements, one or more independent institutional review board (IRB) 
covering  each  institution  participating  in  the  clinical  trial  must  review  and  approve  the  plan  for  any 
clinical  trial  before  it  commences  at  that  institution,  and  the  IRB  must  conduct  continuing  review  and 
reapprove the study at least annually. The IRB must review and approve, among other things, the study 
protocol  and  informed  consent  information  to  be  provided  to  study  subjects.  An  IRB  must  operate  in 
compliance with FDA regulations and other application regulations and internal compliance procedures. 
An  IRB  can  suspend  or  terminate  approval  of  a  clinical  trial  at  its  institution,  or  an  institution  it 

116

represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the 
product candidate has been associated with unexpected serious harm to patients. 

The FDA’s primary objectives in reviewing an IND are to assure the safety and rights of patients and to 
help assure that the quality of the investigation will be adequate to permit an evaluation of the biological 
product’s  safety,  purity  and  potency.  The  decision  to  suspend  or  terminate  development  of  an 
investigational  biological  product  may  be  made  by  either  a  health  authority  body  such  as  the  FDA,  an 
IRB, or by Innate for various reasons. Additionally, some trials are overseen by an independent group of 
qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee 
(DSMB).  This  group  provides  authorization  for  whether  or  not  a  trial  may  move  forward  at  designated 
check  points  based  on  data  from  the  study  that  is  made  available  to  such  DSMB  for  such  purpose. 
Suspension or termination of development during any Phase of clinical trials can occur if it is determined 
that  the  participants  or  patients  are  being  exposed  to  an  unacceptable  health  risk.  Other  reasons  for 
suspension  or  termination  may  be  made  by  Innate  based  on  evolving  business  objectives  and/or  the 
competitive climate. 

Good clinical practices (GCP) 

In most countries, clinical trials also must comply with the current GCP, or cGCP, standards as defined by 
the  International  Council  for  Harmonization  of  Technical  Requirements  for  Registration  of 
Pharmaceuticals  for  Human  Use  (ICH).  Directive  2005/28/EC  dated  April  8,  2005  adopted  the  cGCP 
principles in the context of strengthening the regulatory structure specified by Directive 2001/20/EC. In 
the US, ICH GCP standards are adopted by FDA as guidance. The competent authority designated in each 
Member State to authorize clinical trials must take into consideration, among other factors, the scientific 
value of the study, the safety of the drug and the possible responsibility of the clinical site. 

Conducting clinical trials 

Clinical trials must be carried out in compliance with complex regulations throughout the various Phases 
of clinical development, based on the principle of informed consent by the patient to whom the products 
will be administered. 

Clinical trial Phases 

Clinical trials may be conducted in the United States, in Europe or in other parts of the world as long as 
such trials have been approved by health authorities and ethics committees or IRBs in each country where 
the  trial  is  conducted.  There  are  three  well-established  and  internationally  recognized  clinical  Phases: 
Phase  1,  2  and  3.  This  classification  is  used  by  the  FDA  and  the  EMA,  as  well  as  other  regulatory 
agencies. Each of these clinical Phases is described below.

•

•

Phase 1: The product candidate is initially introduced into healthy human subjects and tested 
for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of 
some  products  for  severe  or  life-threatening  diseases,  such  as  cancer,  especially  when  the 
product  may  be  too  inherently  toxic  to  ethically  administer  to  healthy  volunteers,  the  initial 
human  testing  is  often  conducted  with  patients.  Sponsors  sometimes  designate  their  Phase  1 
trials  as  Phase  1a  or  Phase  1b.  Phase  1b  trials  are  typically  aimed  at  confirming  dosing, 
pharmacokinetics  and  safety  in  larger  number  of  patients.  Some  Phase  1b  studies  evaluate 
biomarkers or surrogate markers that may be associated with efficacy in patients with specific 
types of diseases. 

Phase 2: This Phase involves clinical trials in a limited patient population to identify possible 
adverse  effects  and  safety  risks,  to  preliminarily  evaluate  the  efficacy  of  the  product  for 
specific targeted diseases and to determine dosage tolerance and appropriate dosage. 

117

•

Phase 3: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety 
in  an  expanded  patient  population  at  geographically  dispersed  clinical  study  sites.  These 
clinical trials, generally comparative, are intended to demonstrate the overall risk-benefit ratio 
of the product candidate and provide, if appropriate, an adequate basis for product labeling. 

Post-approval trials, sometimes referred to as Phase 4 studies, may be conducted after marketing approval 
is  obtained.  These  trials  are  used  to  gain  additional  experience  from  the  treatment  of  patients  in  the 
intended  therapeutic  indication.  In  certain  instances,  the  applicable  regulator  may  mandate  the 
performance of Phase 4 clinical trials as a condition of approval. 

In specific situations, certain Phases of development can be merged or even skipped when clear signs of 
efficacy  emerge  in  the  early  Phases  of  development  and  the  product  candidate  is  designed  for  patients 
with  major  unmet  medical  needs.  However,  these  deviations  from  the  standard  pattern  of  development 
must  be  discussed  and  approved  by  health  authorities.  Given  the  high  unmet  medical  need  for  certain 
cancer  patients,  deviations  from  the  typical  Phases  of  development  are  frequent  in  oncology  and 
particularly in the field of immunotherapy. 

Disclosure of clinical trial information 

Sponsors of applicable clinical trials of FDA-regulated drugs are required to register and disclose certain 
clinical  trial  information,  which  is  publicly  available  at  www.clinicaltrials.gov.  Similarly,  in  Europe, 
Sponsors  are  required  to  register  and  disclose  certain  clinical  trial  information  on  a  single  portal,  CTIS 
(Clinical  Trial  Information  System),  replacing  Eudra-CT,  set  up  by  the  European  Medicines  Agency 
(EMA). CTIS is a single entry point centralizing information and databases on clinical trials in the EU. 
Eudra-CT  will  be  definitively  abandoned  at  the  end  of  the  transition  period,  i.e.,  on  January  30,  2025. 
Information  related  to  the  product,  patient  population,  Phase  of  investigation,  study  sites  and 
investigators,  and  other  aspects  of  the  clinical  trial  is  then  made  public  as  part  of  the  registration. 
Sponsors of applicable clinical trials are also obligated to disclose the results of their clinical trials within 
a certain timeframe after completion. Disclosure of the results of these trials may be delayed until the new 
product  or  new  indication  being  studied  has  been  approved,  subject  to  time-based  limitations. 
Competitors  may  use  this  publicly  available  information  to  gain  knowledge  regarding  the  progress  of 
development programs. 

Regulations concerning marketing authorizations 

In order to be marketed, a drug product must have regulatory authorization (known as approval of a New 
Drug Application (NDA) or licensure of a Biologics License Application (BLA) in the United States, a 
Marketing  Authorization  Application  (MAA)  in  the  European  Union  and  a  Great  Britain  Marketing 
Authorisation Application). The competent authorities are the FDA in the United States, the EMA in the 
European Union and the Medicines and Healthcare products Regulatory Agency (MHRA) in the United 
Kingdom. Companies apply for a marketing authorization based on quality, safety and efficacy data. In 
the European Union, the United States and Japan, the dossier is a standard dossier referred to as a CTD, or 
Common Technical Document. Generally, the dossier describes the manufacturing of the drug substance 
(active  substance),  the  manufacturing  of  the  final  product  and  the  clinical  and  non-clinical  studies 
common to all jurisdictions while providing a separate module for region-specific information. 

United States review and approval process for biological products 

In the United States, the FDA licenses complex biological products under the Public Health Service Act, 
or PHSA. In order to obtain approval to market a biological product in the United States, a BLA must be 
submitted  to  the  FDA  with  data  establishing  the  safety,  purity  and  potency  of  the  proposed  biological 
product  for  its  intended  indication.  The  application  includes  all  relevant  data  available  from  pertinent 
preclinical  and  clinical  trials,  including  negative  or  ambiguous  results  as  well  as  positive  findings, 

118

together  with  detailed  information  relating  to  the  product’s  chemistry,  manufacturing,  controls  and 
proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to 
test the safety and effectiveness of a use of a product, or from a number of alternative sources, including 
studies  initiated  by  investigators.  To  support  marketing  authorization,  the  data  submitted  must  be 
sufficient in quality and quantity to establish the safety, purity and potency of the biological product to the 
satisfaction of the FDA. 

The  BLA  is  the  vehicle  through  which  applicants  formally  propose  that  the  FDA  approve  a  new 
biological  product  for  marketing  and  sale  in  the  United  States  for  one  or  more  indications.  Every  new 
biological product candidate must be the subject of an approved BLA before it may be commercialized in 
the United States. Under federal law, the submission of most BLAs is subject to an application user fee 
and  the  sponsor  of  an  approved  BLA  is  also  subject  to  annual  program  user  fees.  These  fees  typically 
increase  annually.  Certain  exceptions  and  waivers  are  available  for  some  of  these  fees,  such  as  an 
exception  from  the  application  fee  for  products  with  orphan  drug  designation  and  a  waiver  for  certain 
small  businesses,  an  exception  from  the  establishment  fee  when  the  establishment  does  not  engage  in 
manufacturing  the  product  during  a  particular  fiscal  year,  and  an  exception  from  the  product  fee  for  a 
product that is the same as another product approved under an abbreviated pathway. 

Following  submission  of  a  BLA,  the  FDA  conducts  a  preliminary  review  of  the  application  generally 
within 60 calendar days of its receipt and strives to inform the sponsor, via the "Day 74 Letter," by the 
74th day after the FDA’s receipt of the submission of whether the application is sufficiently complete to 
permit substantive review. The FDA may request additional information rather than accept the application 
for  filing.  In  this  event,  the  application  must  be  resubmitted  with  the  additional  information.  The 
resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission 
is accepted for filing, the FDA begins an in-depth substantive review. The FDA has agreed to specified 
performance goals in the BLA review process. Under that agreement, FDA committed to review and act 
on  90%  of  applications  seeking  approval  of  original  BLA's  within  10  months  of  the  filing  date  and  on 
90% of original BLA submissions that have been designated for “priority review” within six months of 
the  filing  date.  The  review  process  and  the  Prescription  Drug  User  Fee  Act  goal  date  for  an  original 
application  may  be  extended  by  the  FDA  for  three  additional  months  to  consider  new  information  or 
clarification  provided  by  the  applicant  to  address  an  outstanding  deficiency  identified  by  the  FDA 
following the original submission. 

Before approving an application, the FDA typically will inspect the facility or facilities where the product 
is or will be manufactured. These pre-approval inspections may cover all facilities associated with a BLA 
submission,  including  component  manufacturing,  finished  product  manufacturing,  and  control  testing 
laboratories.  The  FDA  will  not  approve  an  application  unless  it  determines  that  the  manufacturing 
processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent 
production of the product within required specifications. Additionally, before approving a BLA, the FDA 
will typically inspect one or more clinical sites to assure compliance with cGCP. 

As  a  condition  of  approval,  the  FDA  may  require  an  applicant  to  develop  a  Risk  Evaluation  and 
Mitigation  Strategy  (REMS).  REMS  are  required  risk  management  plans  that  use  risk  mitigation 
strategies  beyond  the  professional  labeling  to  ensure  that  the  benefits  of  the  product  outweigh  the 
potential risks. To determine whether a REMS is needed, the FDA will consider the size of the population 
likely  to  use  the  product,  seriousness  of  the  disease/condition  to  be  treated,  expected  benefit  of  the 
product, expected duration of treatment, seriousness of known or potential adverse events, and whether 
the product is a new molecular entity. 

To support its evaluation, the FDA may request advice from an advisory committee.  Preliminary plans on 
whether to hold an advisory committee are included in the Day 74 Letter.  The FDA requests advice from 
advisory  committees  on  a  variety  of  matters,  including  various  aspects  of  clinical  investigations  and 

119

applications for marketing approval of drug products. Advisory committee members are scientific experts 
such as physician-researchers and statisticians, as well as representatives of the public, including patients. 
The  FDA  is  not  bound  by  the  recommendations  of  an  advisory  committee,  but  it  considers  such 
recommendations carefully when making decisions. 

On  the  basis  of  the  FDA’s  evaluation  of  the  application  and  accompanying  information,  including  the 
results  of  the  inspection  of  the  manufacturing  facilities,  the  FDA  may  issue  an  approval  letter  or  a 
complete response letter. An approval letter authorizes commercial marketing of the product with specific 
prescribing  information  for  specific  indications.  A  complete  response  letter  generally  outlines  the 
deficiencies in the submission and may require substantial additional testing or information in order for 
the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’s 
satisfaction in a resubmission of the BLA, the FDA will issue an approval letter. The FDA has committed 
to  reviewing  and  acting  on  90%  of  such  resubmissions  in  two  or  six  months  depending  on  the  type  of 
information  included.  Even  with  submission  of  this  additional  information,  the  FDA  ultimately  may 
decide that the application does not satisfy the regulatory criteria for approval. 

If the FDA approves a product, it may limit the approved indications for use for the product, require that 
contraindications, warnings or precautions be included in the product labeling, require that post-approval 
studies, including Phase 4 clinical trials, be conducted to further assess the product’s safety after approval, 
require testing and surveillance programs to monitor the product after commercialization, or impose other 
conditions,  including  distribution  restrictions  or  other  risk  management  mechanisms,  including  REMS, 
which can materially affect the potential market and profitability of the product. The FDA may prevent or 
limit  further  marketing  of  a  product  based  on  the  results  of  post-marketing  studies  or  surveillance 
programs. 

Registration procedures in the European Union 

To  access  the  European  markets  through  community  procedures,  drug  products  must  be  submitted 
through  the  Centralized  Procedure,  the  Mutual  Recognition  Procedure  or  the  Decentralized  Procedure. 
The  process  for  doing  this  depends,  among  other  things,  on  the  nature  of  the  medicinal  product. 
Regulation (EC) No 726/2004 of the European Parliament and of the Council of March 31, 2004 provides 
for the Centralized Procedure. The Centralized Procedure results in a single MA, granted by the European 
Commission that is valid across the European Economic Area or EEA (i.e., the European Union as well as 
Iceland, Liechtenstein and Norway). The Centralized Procedure is compulsory for human drugs that are: 
(i) derived from biotechnology processes, (ii) contain a new active substance indicated for the treatment 
of  certain  diseases,  such  as  cancer,  HIV/AIDS,  diabetes,  neurodegenerative  diseases,  autoimmune  and 
other  immune  dysfunctions  and  viral  diseases,  (iii)  officially  designated  orphan  medicines  and 
(iv)  advanced-therapy  medicines,  such  as  gene  therapy,  somatic  cell  therapy  or  tissue-engineered 
medicines. 

Under Article 3 of the Regulation (EC) No 726/2004, the Centralized Procedure is optional for any other 
human  medicinal  product  if:  (1)  the  medicinal  product  contains  a  new  active  substance  ;  or  (2)  the 
applicant  shows  that  the  medicinal  product  constitutes  a  significant  therapeutic,  scientific  or  technical 
innovation or that the granting of authorization in accordance with this Regulation is in the interests of 
patients health at the EU level. 

Under the Centralized Procedure in the European Union, the European Medicines Agency (EMA), shall 
ensure that the opinion of the Committee for Medicinal Products for Human Use (CHMP), is given within 
210  days  (Article  6.3).  This  excludes  so-called  clock  stops,  during  which  additional  written  or  oral 
information is to be provided by the applicant in response to questions asked by the CHMP (Article 7). At 
the end of the review period, the CHMP provides its opinion through a scientific assessment report to the 
European Commission. The Commission may then adopt a final decision to grant an MA. Once granted, 

120

the MA is valid across all EEA countries for an initial period of five years. Since 2008, as a consequence 
of a European directive, a marketing authorization is now renewed only once, five years after the initial 
registration.  The  marketing  authorization  shall  be  then  valid  for  an  unlimited  period,  unless  the 
Commission decides, on justified grounds, relating to pharmacovigilance, to proceed with one additional 
five-year renewal. 

National MAs, issued by the competent authorities of the member states of the EEA, are also available; 
however these only cover their respective territory. National MAs may be applied for through the Mutual 
Recognition  Procedure  or  Decentralized  Procedure  in  order  that  multiple  competent  authorities  in 
different member states of the EEA may each issue a national MA in their territory for the same product 
on the back of the same application. National MAs are only available for products not falling within the 
mandatory scope of the Centralized Procedure. 

It is possible for a drug to be withdrawn from the market, upon the request of the health authorities, if a 
serious  problem  arises,  in  particular  a  safety-related  problem.  The  marketing  authorization  is  then 
cancelled.  There  can  be  various  reasons  for  the  withdrawal  of  drugs  from  the  market,  with  the  main 
reasons being public health, major undesirable side effects and non-compliance with manufacturing rules. 

Non-standard regulatory procedures 

Aside  from  the  standard  procedures  of  granting  a  BLA  or  a  European  MA,  as  described  above,  non-
standard regulatory procedures allow a shorter time-to-market for new medicines. 

The following programs that are in place in the United States are intended to facilitate the development 
and/or expedite the review and potential approval of drug products: 

•

•

•

Accelerated Approval: FDA may grant accelerated approval to a product for a serious or life-
threatening  disease  or  condition  upon  a  determination  that  the  product  has  an  effect  on  a 
surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint 
that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely 
to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into 
account  the  severity,  rarity,  or  prevalence  of  the  condition  and  the  availability  or  lack  of 
alternative treatments. This procedure is somewhat comparable to the “conditional approval” 
in the European Union. 

Priority Review: An application for a drug will receive priority review designation if it is for a 
drug that treats a serious condition and, if approved, would provide a significant improvement 
in safety or effectiveness. Priority Review provides for a shorter review clock: the time it takes 
FDA to review a filed BLA is reduced to six months rather than 10 months. This procedure is 
somewhat comparable to the “accelerated assessment” in the European Union. 

The  Fast  Track  Designation:  Section  506(b)  of  the  FDCA  provides  for  the  designation  of  a 
drug  as  a  fast  track  product  “if  it  is  intended,  whether  alone  or  in  combination  with  one  or 
more other drugs, for the treatment of a serious or life-threatening disease or condition, and it 
demonstrates  the  potential  to  address  unmet  medical  needs  for  such  a  disease  or  condition.”  
This  provision  is  intended  to  facilitate  development  and  expedite  review  of  drugs  to  treat 
serious  and  life-threatening  conditions  so  that  an  approved  product  can  reach  the  market 
expeditiously.    For  fast  track  designated  drugs,  sponsors  may  have  a  higher  number  of 
interactions with the FDA.  In addition, the FDA may review sections of the BLA for a fast 
track  designated  drug  on  a  rolling  basis  before  the  complete  application  is  submitted.    Fast 
track  designation  may  be  rescinded  if  the  qualifying  criteria  are  no  longer  met.  Fast  Track 
designation does not necessarily lead to a Priority Review or Accelerated Approval. 

121

•

The Breakthrough Therapy Designation: Section 506(a) of the FDCA provides for designation 
of a drug as a breakthrough therapy “if the drug is intended, alone or in combination with one 
or more other drugs, to treat a serious or life-threatening disease or condition and preliminary 
clinical  evidence  indicates  that  the  drug  may  demonstrate  substantial  improvement  over 
existing therapies on one or more clinically significant endpoints, such as substantial treatment 
effects  observed  early  in  clinical  development.”    The  standard  for  breakthrough  therapy 
designation is not the same as the standard for drug approval as the clinical evidence needed to 
support breakthrough designation is preliminary.  In contrast, as is the case for all drugs, FDA 
will  review  the  full  data  submitted  to  support  approval  of  drugs  designated  as  breakthrough 
therapies to determine whether the drugs are safe and effective for their intended use before 
they are approved for marketing.  The program provides the same advantages of the fast track 
designation, but also includes intensive FDA guidance to promote efficient development and 
FDA organizational commitment.  Breakthrough therapy designation may be rescinded if the 
qualifying criteria are no longer met. 

In  the  European  Union,  non-standard  registration  procedures  under  the  Centralized  Procedures  are  as 
follows: 

•

•

•

•

Conditional marketing authorization: valid one year (instead of five). It is granted only if the 
benefit / risk ratio is positive, if the product addresses unmet medical needs, and if the benefits 
to  public  health  outweigh  the  risks  associated  with  uncertainty  because  of  an  incomplete 
evaluation of the drug (for instance, because of clinical trials still ongoing at the time of the 
evaluation,  or  when  additional  clinical  trials  are  needed).  It  is  renewed  annually  if  an 
appropriate  report  is  submitted  annually  by  the  sponsor.  Once  the  results  of  the  pending 
studies are provided, it can become a “regular” marketing authorization. 

Approval  under  exceptional  circumstances:  a  marketing  authorization  may  be  granted  in 
exceptional  cases,  reviewed  each  year  to  reassess  the  risk-benefit  balance  when  the  initial 
dossier  for  assessment  of  the  drug  cannot  contain  all  required  data,  for  instance  when  the 
condition to be treated is rarely encountered. 

Accelerated assessment : the evaluation process is accelerated (150 days instead of 210 days) 
when a drug is of major interest from the standpoint of public health or in particular from the 
viewpoint of therapeutic innovation.  

The  PRIME  (priority  medicines)  scheme  refers  to  a  process  for  enhanced  interactions  and 
early  dialogue  with  EMA  to  facilitate  the  development  and  speed  up  examination  of  drugs 
which  target  unmet  medical  needs  or  offer  a  major  therapeutic  advantage  over  existing 
treatments.  Through  PRIME,  drug  developers  can  expect  to  be  eligible  for  accelerated 
assessment at the time of application for a marketing authorization.

As part of the EU pharmaceuticals strategy, the EU Commission worked on a revision of the EU’s general 
legislation on medicines for human use. On April 26, 2023 the EU Commission adopted a Directive 
proposal and a Regulation proposal, which represent the largest pharmaceutical reform in over 20 years. 
The revision will impact the global legal framework for medicinal products in the EU, including 
legislation relating to Orphan and pediatric drugs and will review the incentives system (data protection 
and market exclusivity) in place.

Orphan drugs 

Generally, orphan drugs are drugs used for the prevention or treatment of life-threatening or serious rare 
conditions. 

122

In the United States, the 1983 Orphan Drug Act was passed to encourage the development of drugs for 
rare disease or conditions.  In the United States, a rare disease or condition is defined as a disease that 
affects  fewer  than  200,000  people  in  the  United  States,  or  affects  more  than  200,000  but  there  is  no 
reasonable  expectation  that  the  cost  of  developing  and  making  available  a  drug  for  such  disease  or 
condition in the United States will be recovered from U.S. sales of the drug.  The FDA has authority to 
grant orphan drug designation to a drug or biological product to prevent, diagnose or treat a rare disease 
or  condition,  a  designation  which  carries  with  it  the  following  incentives:  the  possibility  of  obtaining 
research  grants  from  the  American  government  for  clinical  trials;  tax  credits  for  a  portion  of  research 
costs; a possible exemption from user fees; and the potential for a seven-year period of exclusivity if a 
marketing authorization is granted. 

Regarding  orphan  drug  exclusivity,  if  a  product  with  orphan  drug  designation  receives  the  first  FDA 
approval  for  the  disease  or  condition  for  which  it  has  such  designation  or  for  a  select  indication  or  use 
within the rare disease or condition for which it was designated, the product will generally receive orphan 
drug  exclusivity.  Orphan  drug  exclusivity  means  that  the  FDA  may  not  approve  another  sponsor’s 
marketing application for the same drug for the same use or indication for seven years, except in certain 
limited circumstances. Orphan drug exclusivity does not block the approval of a different product for the 
same  rare  disease  or  condition,  nor  does  it  block  the  approval  of  the  same  product  for  different 
indications.  If  a  product  designated  as  an  orphan  drug  ultimately  receives  marketing  approval  for  an 
indication  broader  than  what  was  designated  in  its  orphan  drug  application,  it  may  not  be  entitled  to 
exclusivity. 

Orphan  exclusivity  will  not  bar  approval  of  another  product  under  certain  circumstances,  including  if  a 
subsequent  product  that  is  the  same  biologic  for  the  same  use  or  indication  is  shown  to  be  clinically 
superior  to  the  approved  product  on  the  basis  of  greater  effectiveness  than  the  approved  drug,  greater 
safety  in  a  substantial  portion  of  the  target  populations,  or  demonstration  of  a  major  contribution  to 
patient care.  Additionally, FDA may approve another application for the same biologic for the same use 
or  condition  notwithstanding  the  applicability  of  orphan  drug  exclusivity,  if  the  company  with  orphan 
drug exclusivity is not able to assure a sufficient quantity of the drug. 

In  the  European  Union,  equivalent  legislation  has  been  adopted  to  promote  treatments  for  rare  diseases 
(Regulation  141/2000/EC  of  December  16,  1999,  as  amended  by  Regulation  847/2000/EC  of  April  27, 
2000). A medicinal product may be designated as orphan if: (a) it is intended for the diagnosis, prevention 
or  treatment  of  a  life-threatening  or  chronically  debilitating  condition  affecting  not  more  than  five  in 
10,000  persons  in  the  European  Union  when  the  application  is  made,  or  (b)  it  is  intended  for  the 
diagnosis,  prevention  or  treatment  of  a  life-threatening,  seriously  debilitating  or  serious  and  chronic 
condition  in  the  European  Union  and  that  without  incentives  it  is  unlikely  that  the  marketing  of  the 
medicinal  product  in  the  European  Union  would  generate  sufficient  return  to  justify  the  necessary 
investment.

For either of these conditions, the applicant must demonstrate that there exists no satisfactory method of 
diagnosis, prevention or treatment of the condition in question that has been authorized in the EU or, if 
such method exists, the medicinal product will be of significant benefit to those affected by that condition. 

Medicinal products receiving orphan designation in the European Union can receive 10 years of market 
exclusivity,  during  which  time  no  similar  medicinal  product  can  be  submitted  for  the  same  therapeutic 
indication.  An  orphan  product  can  also  obtain  an  additional  two  years  of  market  exclusivity  in  the 
European  Union  for  pediatric  studies  (in  this  case  for  orphan  drugs  no  extension  to  any  supplementary 
protection  certificate  can  be  granted,  see  further  detail  below).  Orphan  medicinal  products  are  also 
eligible for financial incentives such as reduction of fees or fee waivers and scientific assistance for study 
proposals.  (Articles  6  and  9  of  the  above-mentioned  regulation).  The  application  for  orphan  drug 

123

designation  must  be  submitted  before  the  application  for  marketing  authorization  (Article  5).  The 
applicant  will  receive  a  fee  reduction  for  the  marketing  authorization  application  if  the  orphan  drug 
designation  has  been  granted,  but  not  if  the  designation  is  still  pending  at  the  time  the  marketing 
authorization  is  submitted.  Orphan  drug  designation  does  not  convey  any  advantage  in,  or  shorten  the 
duration of, the regulatory review and approval process.

The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established 
that  the  product  no  longer  meets  the  criteria  for  orphan  designation,  for  example,  if  the  product  is 
sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity  (Article  8).  However,  marketing 
authorization may be granted to a similar medicinal product for the same indication at any time if: 

•

•

•

the  holder  of  the  marketing  authorization,  or  MA,  for  the  original  orphan  medicinal  product 
has given its consent to the second applicant; 

the  holder  of  the  MA  for  the  original  orphan  medicinal  product  cannot  supply  sufficient 
quantities of the orphan medicinal product; or 

the  second  applicant  can  establish  in  the  application  that  its  product,  although  similar  to  the 
orphan  medicinal  product  already  authorized,  is  safer,  more  effective  or  otherwise  clinically 
superior. 

Registration procedures outside of the European Union and the United States 

In  addition  to  regulation  in  the  United  States  and  the  European  Union,  a  variety  of  foreign  regulations 
govern  clinical  trials,  commercial  sales  and  distribution  of  drugs.  Pharmaceutical  firms  who  wish  to 
market their medicinal drugs outside the European Union and the United States must submit marketing 
authorization application to the national authorities of the concerned countries, such as the Pharmaceutical 
and  Medical  Device  Agency  (PMDA)  in  Japan.  The  approval  process  varies  from  jurisdiction  to 
jurisdiction and the time to approval may be longer or shorter than that required by the FDA or European 
Commission.

Of note, in the United Kingdom (which comprises Great Britain and Northern Ireland), Great Britain is no 
longer  covered  by  EU  centralized  procedures  for  MAs  (under  the  Northern  Ireland  Protocol,  EU 
centralized procedures for MAs continue to be recognized in Northern Ireland). For a period of two years 
from January 1, 2021, when determining an application for a Great Britain Marketing Authorization, the 
MHRA was allowed to rely on  on a decision taken by the European Commission on the approval of a 
new MA in the centralized procedure (the European Decision Reliance Procedure). On January 1, 2024, a 
new  international  recognition  framework  procedure  (IRP)  replaced  the  European  Decision  Reliance 
Procedure. Under the IRP,  the MHRA may take into account the approval of MAs made by the EMA and 
certain  other  regulators.  The  MHRA  also  has  the  power  to  take  into  account  MAs  approved  in  EU 
Member  States  through  decentralized  or  mutual  recognition  procedures  with  a  view  to  more  quickly 
granting an MA in the United Kingdom.

Post-approval regulations 

Post-approval regulation in the United States 

Biologics manufactured or distributed pursuant to FDA licensure are subject to pervasive and continuing 
regulation  by  the  FDA,  including,  among  other  things,  requirements  relating  to  recordkeeping,  periodic 
reporting,  product  sampling  and  distribution,  advertising  and  promotion  and  reporting  of  adverse 
experiences with the product. After approval, most changes to the approved product, such as adding new 
indications  or  other  labeling  claims,  are  subject  to  prior  FDA  review  and  approval.  There  are  also 
continuing, annual user fee requirements for any marketed products and the establishments at which such 

124

products  are  manufactured,  as  well  as  new  application  fees  for  supplemental  applications  with  clinical 
data. 

In  addition,  manufacturers  and  other  entities  involved  in  the  manufacture  and  distribution  of  approved 
products are required to register their establishments with the FDA and state agencies, and are subject to 
periodic  unannounced  inspections  by  the  FDA  and  aforementioned  state  agencies  for  compliance  with 
drug manufacturing regulations, including current good manufacturing practices (cGMP). Changes to the 
manufacturing  process  are  strictly  regulated  and  often  require  prior  FDA  approval  before  being 
implemented.  FDA  regulations  also  require  investigation  and  correction  of  any  deviations  from  cGMP 
and  impose  reporting  and  documentation  requirements  upon  the  sponsor  and  any  third-party 
manufacturers that the sponsor may decide to use.  

Once  an  approval  is  granted,  the  FDA  may  withdraw  the  approval  if  compliance  with  regulatory 
requirements and standards is not maintained or if problems occur after the product reaches the market. 
Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse  events  of 
unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory 
requirements, may result in revising the approved labeling to add new safety information; imposing post-
market  studies  or  clinical  trials  to  assess  new  safety  risks;  or  imposing  distribution  or  other  restrictions 
under a REMS program. Other potential consequences include, among other things: 

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, suspension of the approval, or 
complete withdrawal of the product from the market or product recalls; 

fines, warning letters or holds on post-approval clinical trials; 

refusal  of  the  FDA  to  approve  pending  applications  or  supplements  to  approved  BLAs,  or 
suspension or revocation of product license approvals; 

product seizure or detention, or refusal to permit the import or export of products; and 

injunctions or the imposition of civil or criminal penalties. 

In  addition,  the  distribution  of  prescription  pharmaceutical  products  is  subject  to  the  Prescription  Drug 
Marketing Act (PDMA) and its implementing regulations, as well as the Drug Supply Chain Security Act 
(DSCSA),  which  respectively  regulate  the  distribution  and  tracing  of  prescription  drug  samples  at  the 
federal level and set floor and ceiling standards for the regulation of wholesale distributors by the states. 
PDMA, its implementing regulations and state laws limit the distribution of prescription pharmaceutical 
product  samples,  and  DSCSA  imposes  requirements  to  ensure  accountability  during  distribution  and  to 
identify  and  remove  counterfeit  and  other  illegitimate  products  from  the  market,  each  among  other 
objectives. 

The FDA strictly regulates labels/labeling, advertising and promotion of prescription drugs that are placed 
on  the  market.  The  FDA-required  labeling  sets  forth  the  conditions  of  use  under  which  the  licensed 
biologics  has  been  shown  to  meet  the  relevant  standard  for  marketing  and  provides  directions  and 
information on how to use the product safely and effectively under those conditions. Licensed biologics 
may be promoted only for the approved indications and in accordance with the provisions of the approved 
label,  including  information  consistent  with  the  FDA  required  labeling  and  not  otherwise  false  or 
misleading.  The  FDA  and  other  agencies  actively  enforce  the  laws  and  regulations  prohibiting  the 
promotion of off-label uses. A company that is found to have improperly promoted off-label uses may be 
subject to significant liability. 

Patent term restoration and extension in the United States 

A patent claiming a new biologic product may be eligible for a limited patent term extension under the 
Hatch-Waxman  Act,  which  permits  a  patent  restoration  of  up  to  five  years  for  patent  term  lost  during 

125

product development and the FDA regulatory review period. A regulatory review period consists of two 
periods  of  time:  a  testing  phase  and  an  approval  phase.  The  restoration  period  granted  on  a  patent 
covering a product is calculated as one-half the testing phase (the time between the exemption to permit 
the clinical investigations of the drug product becomes effective and start of the approval phase) plus the 
approval phase (the time between the submission date of an application and the ultimate approval date). A 
maximum of five years can be restored to a patent and patent term extension cannot be used to extend the 
remaining term of a patent past a total of 14 years from the product’s approval date. Additionally, only 
one patent applicable to an approved product is eligible for the extension, the application for the extension 
must  be  submitted  prior  to  the  expiration  of  the  patent  in  question,  and  only  those  claims  covering  the 
approved drug, a method for using it, or a method for manufacturing it may be extended. A patent that 
covers multiple products for which approval is sought can only be extended in connection with one of the 
approvals. The USPTO reviews and approves the application for any patent term extension or restoration 
in consultation with the FDA. For more information regarding the risks related to patent term restoration 
and extension, please see “Risk Factors—Risks Related to Intellectual Property Rights—If the Company 
does  not  obtain  protection  under  the  Hatch-Waxman  Amendments  and  similar  non-U.S.  legislation  for 
extending the term of patents covering Lumoxiti and each of its product candidates, its business may be 
materially harmed.” 

Healthcare law and regulation in the United States 

Healthcare providers and third-party payors play a primary role in the recommendation and prescription 
of biologic products that are granted marketing approval. Arrangements with providers, consultants, third-
party payors and customers are subject to broadly applicable fraud and abuse, anti-kickback, false claims 
laws,  transparency  laws  and  patient  data  privacy  laws  and  regulations  and  other  healthcare  laws  and 
regulations  that  may  constrain  business  and/or  financial  arrangements.  Restrictions  under  applicable 
federal and state healthcare laws and regulations, include the following:

•

•

•

•

the U.S. Anti-Kickback Statute, which prohibits, among other things, persons and entities from 
knowingly  and  willfully  soliciting,  offering,  paying,  receiving  or  providing  remuneration, 
directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual 
for, or the purchase, order or recommendation of, any good or service, for which payment may 
be  made,  in  whole  or  in  part,  under  a  federal  healthcare  program  such  as  Medicare  and 
Medicaid; 

the  U.S.  civil  and  criminal  false  claims  laws,  including  the  civil  False  Claims  Act,  and  civil 
monetary  penalties  laws,  which  prohibit  individuals  or  entities  from,  among  other  things, 
knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,  claims  for 
payment  that  are  false,  fictitious  or  fraudulent  or  knowingly  making,  using  or  causing  to  be 
made  or  used  a  false  record  or  statement  to  avoid,  decrease  or  conceal  an  obligation  to  pay 
money to the federal government;

the U.S. Health Insurance Portability and Accountability Act of 1996 (HIPAA), which created 
additional  federal  criminal  laws  that  prohibit,  among  other  things,  knowingly  and  willfully 
executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or 
making false statements relating to healthcare matters; 

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health 
Act,  and  their  respective  implementing  regulations,  including  the  Final  Omnibus  Rule 
published  in  January  2013,  which  impose  obligations  on  covered  entities  and  their  business 
associates,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy, 
security and transmission of individually identifiable health information; 

126

•

•

the federal transparency requirements known as the federal Physician Payments Sunshine Act, 
under  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care 
Education  Reconciliation  Act,  or  the  ACA,  which  requires  certain  manufacturers  of  drugs, 
devices,  biologics  and  medical  supplies  to  report  annually  to  the  Centers  for  Medicare  & 
Medicaid  Services  (CMS)  within  the  United  States  Department  of  Health  and  Human 
Services, information related to payments and other transfers of value made by that entity to 
physicians  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests  held  by 
physicians and their immediate family members; and 

analogous state and foreign laws and regulations, such as state anti-kickback and false claims 
laws,  which  may  apply  to  healthcare  items  or  services  that  are  reimbursed  by  non-
governmental third-party payors, including private insurers. 

Some  state  laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s 
voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  federal 
government in addition to requiring manufacturers to report information related to payments to physicians 
and  other  health  care  providers  or  marketing  expenditures.  Certain  state  laws  require  the  reporting  of 
information relating to drug and biologic pricing; and some state and local laws require the registration of 
pharmaceutical sales representatives. State and foreign laws also govern the privacy and security of health 
information in some circumstances, many of which differ from each other in significant ways and often 
are not preempted by HIPAA, thus complicating compliance efforts. 

Failure to comply with these laws or any other governmental regulations as applicable, could result in the 
imposition  of  significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement, 
imprisonment,  possible  exclusion  from  government  funded  healthcare  programs,  such  as  Medicare  and 
Medicaid,  additional  integrity  reporting  requirements  and  oversight,  as  well  as  contractual  damages, 
reputational harm, diminished profits and future earnings, and curtailment of operations. 

Healthcare reform in the United States 

A primary trend in the United States healthcare industry and elsewhere is cost containment. There have 
been a number of federal and state proposals and changes during the last few years regarding the pricing 
of  pharmaceutical  and  biopharmaceutical  products,  limiting  coverage  and  reimbursement  for  biologics 
and other medical products, government control and other changes to the healthcare system in the United 
States. 

On March 23, 2010, President Obama signed into law the ACA, which includes a number of healthcare 
reform  provisions  and  requires  most  U.S.  citizens  to  have  health  insurance.  The  ACA,  among  other 
things,  imposed  a  significant  annual  fee  on  companies  that  manufacture  or  import  branded  prescription 
drug  products;  addressed  a  new  methodology  by  which  rebates  owed  by  manufacturers  under  the 
Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or 
injected;  increased  the  minimum  Medicaid  rebates  owed  by  manufacturers  under  the  Medicaid  Drug 
Rebate  Program  and  extended  the  rebate  program  to  individuals  enrolled  in  Medicaid  managed  care 
organizations;  and  establishes  a  new  Medicare  Part  D  coverage  gap  discount  program,  in  which 
manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices of applicable brand 
drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the  manufacturer’s 
outpatient drugs to be covered under Medicare Part D. Substantial new provisions affecting compliance 
also have been added, which may require modification of business practices with healthcare practitioners. 
The ACA also revised the definition of “average manufacturer price” for reporting purposes, which could 
increase the amount of Medicaid drug rebates to states.  

There  have  been  judicial,  congressional,  and  executive  branch  efforts  to  repeal,  modify  or  delay  the 
implementation  of  the  law.  In  July  and  December  2018,  CMS  published  final  rules  with  respect  to 

127

permitting  further  collections  and  payments  to  and  from  certain  ACA  qualified  health  plans  and  health 
insurance  issuers  under  its  risk  adjustment  program  in  response  to  the  outcome  of  federal  district  court 
litigation  regarding  the  method  CMS  uses  to  determine  this  risk  adjustment.  While  Congress  has  not 
passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the 
ACA have been signed into law. The Tax Cuts and Jobs Act of 2017 includes a provision that repealed, 
effective  January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the  ACA  on  certain 
individuals  who  fail  to  maintain  qualifying  health  coverage  for  all  or  part  of  a  year  that,  commonly 
referred to as the “individual mandate.” On December 14, 2018, a Texas U.S. District Court Judge ruled 
that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by the U.S. 
Congress as part of the Tax Cuts and Jobs Act of 2017. Additionally, on June 17, 2021, the U.S. Supreme 
Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety 
because  the  "individual  mandate"  was  repealed  by  Congress.  Thus  the  ACA  remains  in  effect  in  its 
current  form.  It  is  unclear  how  judicial  and  Congressional  challenges  and  other  efforts  to  repeal  and 
replace  the  ACA  will  impact  the  ACA.  The  Company  continues  to  evaluate  how  the  ACA  and  recent 
efforts to limit the implementation of the ACA will impact its business.

Other  legislative  changes  have  been  proposed  and  adopted  in  the  United  States  since  the  ACA  was 
enacted.  For  example,  in  August  2011,  the  Budget  Control  Act  of  2011,  among  other  things,  included 
aggregate reductions to Medicare payments to providers and suppliers of 2% per fiscal year, starting in 
2013, and, due to subsequent legislative amendments to the statute, will remain in effect through 2032, 
unless additional Congressional action is taken .

The  American  Taxpayer  Relief  Act  of  2012  further  reduced  Medicare  payments  to  several  providers, 
including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations 
period for the government to recover overpayments to providers from three to five years. 

Furthermore,  there  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with 
respect  to  drug  pricing  practices.  There  have  been  several  recent  U.S.  Congressional  inquiries  and 
proposed  and  enacted  federal  and  state  legislation  designed  to,  among  other  things,  bring  more 
transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, 
reduce the cost of drugs under Medicare, and reform government program reimbursement methodologies 
for drugs. 

For example, in August 2022, the Inflation Reduction Act of 2022 was signed into law. This legislation 
contains substantial drug pricing reforms, including the establishment of a drug price negotiation program 
within the U.S. Department of Health and Human Services that would require manufacturers to charge a 
negotiated “maximum fair price” for certain selected drugs or pay an excise tax for noncompliance, the 
establishment of rebate payment requirements on manufacturers of certain drugs payable under Medicare 
Parts  B  and  D  to  penalize  price  increases  that  outpace  inflation,  and  requires  manufacturers  to  provide 
discounts on Part D drugs.  The Inflation Reduction Act of 2022 also caps Medicare beneficiaries’ annual 
out-of-pocket drug expenses. Substantial penalties can be assessed for noncompliance with the IRA drug 
pricing provisions.  Provisions of the IRA are subject to legal challenges, and the full impact of the IRA 
on the pharmaceutical industry remains uncertain.

The U.S. Congress and the current administration have each indicated that it will continue to seek new 
legislative and/or administrative measures to control drug costs.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed 
to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement 
constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and 
transparency measures, and, in some cases, designed to encourage importation from other countries and 
bulk purchasing. 

128

Pharmacovigilance system in the European Union 

An  MA  holder  in  the  EU  must  establish  and  maintain  a  pharmacovigilance  system  and  appoint  an 
individual  qualified  person  for  pharmacovigilance  (QPPV),  who  is  responsible  for  oversight  of  the 
pharmacovigilance  system.  Key  obligations  include  expedited  reporting  of  suspected  serious  adverse 
reactions and submission of periodic safety update reports (PSURs). 

All new MA applications must include a risk management plan (RMP) describing the risk management 
system  that  the  company  will  put  in  place  and  documenting  measures  to  prevent  or  minimize  the  risks 
associated  with  the  product.  The  regulatory  authorities  may  also  impose  specific  obligations  as  a 
condition  of  the  MA.  Such  risk-minimization  measures  or  post-authorization  obligations  may  include 
additional  safety  monitoring,  more  frequent  submission  of  PSURs  or  the  conduct  of  additional  clinical 
trials  or  post-authorization  safety  studies.  RMPs  and  PSURs  are  routinely  available  to  third  parties 
requesting access, subject to limited redactions. 

Advertising regulation in the European Union 

All advertising and promotional activities for the product must be consistent with the approved summary 
of  product  characteristics,  and  therefore  all  off-label  promotion  is  prohibited.  Direct-to-consumer 
advertising  of  prescription  medicines  is  also  prohibited  in  the  European  Union.  Although  general 
requirements for advertising and promotion of medicinal products are established under European Union 
directives, the details are governed by regulations in each European Union Member State and can differ 
from one country to another. 

If  the  Company  fails  to  comply  with  applicable  foreign  regulatory  requirements,  the  Company  may  be 
subject  to  fines,  suspension  or  withdrawal  of  regulatory  approvals,  product  recalls,  seizure  of  products, 
operating restrictions and criminal prosecution. 

Pharmaceutical coverage, pricing and reimbursement 

European Union 

In  the  European  Union,  pricing  and  reimbursement  schemes  vary  widely  from  country  to  country.  In 
some  countries,  products  may  be  marketed  only  after  a  reimbursement  price  has  been  agreed.  Some 
countries  may  require  the  completion  of  additional  studies  that  compare  the  cost-effectiveness  of  a 
particular product candidate to currently available therapies or so-called health technology assessments, in 
order to obtain reimbursement or pricing approval. For example, the European Union provides options for 
its  member  states  to  restrict  the  range  of  products  for  which  their  national  health  insurance  systems 
provide  reimbursement  for  and  to  control  the  prices  of  medicinal  products  for  human  use.  European 
Union member states may approve a specific price for a product or it may instead adopt a system of direct 
or indirect controls on the profitability of the company placing the product on the market. Other member 
states allow companies to fix their own prices for products, but monitor and control prescription volumes 
and issue guidance to physicians to limit prescriptions. Recently, many countries in the European Union 
have increased the amount of discounts required on pharmaceuticals and these efforts could continue as 
countries  attempt  to  manage  healthcare  expenditures,  especially  in  light  of  the  severe  fiscal  and  debt 
crises experienced by many countries in the European Union. The downward pressure on health care costs 
in general, particularly prescription products, has become intense. As a result, increasingly high barriers 
are  being  erected  to  the  entry  of  new  products.  Political,  economic  and  regulatory  developments  may 
further  complicate  pricing  negotiations,  and  pricing  negotiations  may  continue  after  reimbursement  has 
been obtained. Reference pricing used by various European Union member states, and parallel trade, i.e., 
arbitrage between low-priced and high-priced member states, can further reduce prices. There can be no 
assurance  that  any  country  that  has  price  controls  or  reimbursement  limitations  for  pharmaceutical 

129

products will allow favorable reimbursement and pricing arrangements for any products, if approved in 
those countries. 

United States 

In  the  United  States,  patients  who  have  treatments  prescribed  for  their  conditions  and  providers 
performing  the  prescribed  services  generally  rely  on  third-party  payors  to  reimburse  all  or  part  of  the 
associated healthcare costs. Significant uncertainty exists as to the coverage and reimbursement status of 
products approved by the FDA. Thus, even if a product candidate is approved, sales of the product will 
depend, in part, on the extent to which third-party payors, including government health programs in the 
United  States  such  as  Medicare  and  Medicaid,  commercial  health  insurers  and  managed  care 
organizations,  provide  coverage,  and  establish  adequate  reimbursement  levels  for,  the  product.  The 
process  for  determining  whether  a  payor  will  provide  coverage  for  a  product  may  be  separate  from  the 
process for setting the price or reimbursement rate that the payor will pay for the product once coverage is 
approved.  Third-party  payors  are  increasingly  challenging  the  prices  charged,  examining  the  medical 
necessity, and reviewing the cost-effectiveness of medical products and services and imposing controls to 
manage costs. Third-party payors may limit coverage to specific products on an approved list, also known 
as a formulary, which may not include all of the approved products for a particular indication. 

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a 
company may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical 
necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other 
comparable  marketing  approvals.  Nonetheless,  product  candidates  may  not  be  considered  medically 
necessary  or  cost  effective.  A  decision  by  a  third-party  payor  not  to  cover  a  product  candidate  could 
reduce physician utilization once the product is approved, which could have a material adverse effect on 
sales, results of operations and financial condition. Additionally, a payor’s decision to provide coverage 
for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s 
determination  to  provide  coverage  for  a  product  does  not  assure  that  other  payors  will  also  provide 
coverage  and  reimbursement  for  the  product,  and  the  level  of  coverage  and  reimbursement  can  differ 
significantly from payor to payor. 

The containment of healthcare costs also has become a priority of federal, state and foreign governments 
and the prices of products have been a focus in this effort. Governments have shown significant interest in 
implementing  cost-containment  programs,  including  price  controls,  restrictions  on  reimbursement  and 
requirements  for  substitution  of  generic  products.  Adoption  of  price  controls  and  cost-containment 
measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, 
could  further  limit  a  company’s  revenue  generated  from  the  sale  of  any  approved  products.  Coverage 
policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and 
reimbursement  status  is  attained  for  one  or  more  products  for  which  a  company  or  its  collaborators 
receive  marketing  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be 
implemented in the future. 

Anti-corruption, anti-kickback and transparency regulations 

Arrangements  with  healthcare  providers,  physicians,  third-party  payors  and  customers  can  expose 
pharmaceutical  manufactures  to  broadly  applicable  anti-bribery,  fraud  and  abuse  and  other  healthcare 
laws  and  regulations,  which  may  constrain  the  business  or  financial  arrangements  and  relationships 
through which such companies sell, market and distribute pharmaceutical products. 

More  specifically,  each  of  the  above-mentioned  steps  of  the  development  of  therapeutic  products  for 
human use is heavily regulated and therefore involves significant interaction with public officials which is 
likely to cause a risk of corruption or bribery. For instance, in many countries, hospitals are operated by 
the  government,  and  doctors  and  other  hospital  employees  are  considered  foreign  officials.  Certain 

130

payments to hospitals in connection with clinical trials and other work have been deemed to be improper 
payments to government officials and have led to enforcement actions. That is why business activity may 
be  subject  to  anti-bribery  or  anti-corruption  laws,  regulations  or  rules  of  other  countries  in  which  the 
Company operates, including without limitation the Foreign Corrupt Practices Act, the U.K. Bribery Act 
or the French Sapin 2 Law. 

These  statutes  generally  prohibit  offering,  promising,  giving,  or  authorizing  others  to  give  anything  of 
value,  either  directly  or  indirectly,  to  a  government  or  a  foreign  government  official  or  employees  of 
public  international  organizations  in  order  to  influence  official  action,  or  otherwise  obtain  or  retain 
business.  The  implementation  of  these  statutes  may  also  impose  internal  compliance  programs, 
procedures  and  guidelines  to  detect  and  report  any  suspicious  activities  and  to  mitigate  any  risks  of 
noncompliance which may occur. 

In addition, the Company may be subject to specific healthcare regulations, including, without limitation: 

•

•

the  French  “transparency”  provisions,  or  “French  Sunshine  Act”  (Articles  L.  1453-1  and 
D.  1453-1  and  seq.  of  the  French  Public  Health  Code  or  PHC),  which  contains  provisions 
regarding transparency of fees received by some healthcare professionals from industries, i.e. 
companies  manufacturing  or  marketing  healthcare  products  (medicinal  products,  medical 
devices, etc.) in France. According to the provisions, these companies shall publicly disclose 
(on a specific public website available at https://transparence.sante.gouv.fr) the advantages and 
fees  paid  to  healthcare  professionals  amounting  to  €10  or  above,  as  well  as  the  agreements 
concluded with the latter, along with detailed information about each agreement (the precise 
subject matter of the agreement, the date of signature of the agreement, its end date, the total 
amount paid to the healthcare professional, etc.); and 

the French “anti-gift” provisions (Articles L.1453-3 to L.1453-12 PHC), setting out a general 
prohibition  of  payments  and  rewards  from  industries,  i.e.  companies  manufacturing  or 
marketing health products to healthcare professionals (HCP), healthcare organizations (HCO), 
healthcare  associations  and  students  with  limited  exceptions,  and  strictly  defining  the 
conditions  under  which  such  payments  or  awards  are  lawful.  The  regime  entails  strict 
formalities  depending  on  the  amount  paid,  when  authorized,  to  the  HCP,  HCO,  students  or 
associations.

Data protection rules 

The  Regulation  2016/679,  known  as  the  General  Data  Protection  Regulation,  or  GDPR,  that  came  into 
force on May 25, 2018, as well as EU Member State implementing legislations, apply to the collection 
and processing of personal data, including health-related information, by companies located in the EU, or 
in certain circumstances, by companies located outside of the EU and processing personal information of 
individuals located in the EU. 

These  laws  impose  strict  obligations  on  the  ability  to  process  personal  data,  including  health-related 
information, in particular in relation to their collection, use, disclosure and transfer. 

Also, in certain countries, in particular France, the conduct of clinical trials is subject to compliance with 
specific provisions of the Act No.78-17 of January 6, 1978 on Information Technology, Data Files and 
Civil  Liberties,  as  amended.  These  provisions  require,  among  others,  the  filing  of  compliance 
undertakings  with  “standard  methodologies”  and  a  specific  framework  applicable  to  the  retention  of 
personal  data  when  researching  in  the  health  sector  (July  2020)  adopted  by  the  French  Data  Protection 
Authority (the CNIL), or, if not compliant, obtaining a specific authorization from the CNIL.

Item 5. Operating and Financial Review and Prospects.

You should read the following discussion of the Company financial condition and results of operations in 
conjunction  with  the  “Selected  Consolidated  Financial  Data”  and  its  consolidated  financial  statements 
and  the  related  notes  thereto  included  elsewhere  in  this  Annual  Report.  In  addition  to  historical 
information,  the  following  discussion  and  analysis  contains  forward-looking  statements  that  reflect  the 
Company plans, estimates and beliefs. The Company actual results and the timing of events could differ 
materially  from  those  anticipated  in  the  forward-looking  statements.  Factors  that  could  cause  or 
contribute  to  these  differences  include  those  discussed  below  and  elsewhere  in  this  Annual  Report, 
particularly in sections titled “Item 3.D – Risk Factors” and “Special Note Regarding Forward-Looking 
Statements.”  The  Company  audited  consolidated  financial  statements  as  of  and  for  the  years  ended 
December 31, 2021, 2022 and 2023 have been prepared in accordance with IFRS as issued by the IASB, 
which  may  differ  in  material  respects  from  generally  accepted  accounting  principles  in  other 
jurisdictions, including the United States. 

Overview 

Innate is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. 
Its innovative approach aims to harness the innate immune system through therapeutic antibodies and its 
ANKET® (Antibody-based NK cell Engager Therapeutics) proprietary platform.

Innate’s portfolio includes lead proprietary program lacutamab, developed in advanced form of cutaneous 
T cell lymphomas and peripheral T cell lymphomas, monalizumab developed with AstraZeneca in non-
small  cell  lung  cancer,  as  well  as  ANKET®  multi-specific  NK  cell  engagers  to  address  multiple  tumor 
types. The Company has developed, internally and through its business development strategy, a broad and 
diversified portfolio including seven clinical drug candidates and a robust preclinical pipeline. Innate has 

132

entered  into  collaborations  with  leaders  in  the  biopharmaceutical  industry,  such  as  AstraZeneca,Sanofi 
and  Takeda.  Innate  Pharma  believes  its  drug  candidates  and  clinical  development  approach  are 
differentiated from current immuno-oncology therapies and have the potential to significantly improve the 
clinical outcome for patients with cancer.

Since its inception, the Company has devoted substantially all of its financial resources to research and 
development efforts, including conducting preclinical studies and clinical trials of its product candidates, 
providing general and administrative support for its operations and protecting its intellectual property. 

As  of  December  31,  2023,  the  Company  had  €102.3  million  in  cash,  cash  equivalents,  short-term 
investments and non-current financial assets. Since its inception, the Company has raised a total of €311.4 
million  through  the  sale  of  equity  securities, including  €33.7  million  in  the  initial  public  offering  of  its 
ordinary shares on Euronext Paris in 2006 and €66.0 million in the initial public offering of our ordinary 
shares on Euronext and ADS on The Nasdaq Global Select Market, or Nasdaq, in 2019. As of December 
31,  2023,  the  Company  has  also  received  $635.4  million  (€560.1  million)  in  payments  from  its 
collaborators, including AstraZeneca, since 2011, excluding payments received for purchases of its equity 
securities by its collaborators. 

The Company has significant agreements with AstraZeneca, Sanofi and Takeda pursuant to which it has 
the right to earn milestone and royalty payments. The Company has other license agreements, pursuant to 
which  it  has  acquired  intellectual  property  and  under  which  the  Company  will  be  required  to  make 
payments  to  the  counterparty  upon  the  achievement  of  certain  milestone  events  and  commercial  sales 
related to its product candidates. 

The  Company  has  incurred  net  losses  in  each  year  since  its  inception  except  for  the  years  ended 
December 31, 2016 and 2018. The Company net income (loss) was €(52.8) million, €(58.1) million and 
€(7.6) million for the years ended December 31, 2021, 2022 and 2023, respectively. Substantially all of 
its net losses have resulted from costs incurred in connection with its research and development programs 
and  from  selling,  general  and  administrative  expenses  associated  with  its  operations.  As  the  Company 
continues  advancing  its  product  candidates  through  research  and  development  programs,  the  Company 
expects to continue to incur significant expenses and may again incur operating losses in future periods. 
The Company anticipates that such expenses will increase substantially if and as the Company: 

•

•

•

•

•

•

•

•

•

•

•

•

continues the research and development of its product candidates; 

initiates clinical trials for, or additional preclinical development of, its product candidates; 

further develops and refines the manufacturing processes for its product candidates; 

changes or adds manufacturers or suppliers of biological materials; 

seeks  regulatory  and  marketing  authorizations  for  any  of  its  product  candidates  that 
successfully complete development; 

seeks to identify and validate additional product candidates; 

acquires or licenses other product candidates, technologies or biological materials; 

makes milestone, royalty or other payments under any current or future license agreements; 

obtains, maintains, protects and enforces its intellectual property portfolio; 

secures manufacturing arrangements for commercial production; 

seeks to attract and retain new and existing skilled personnel; 

creates additional infrastructure to support its operations as a U.S. public company and incurs 
increased legal, accounting, investor relations and other expenses; and 

133

•

experiences delays or encounters issues with any of the above. 

The  Company  anticipates  that  it  will  need  to  raise  additional  funding,  prior  to  completing  clinical 
development of any of its product candidates. Until such time that the Company can generate significant 
revenues from sales of its product candidates, if approved, the Company expects to finance its operating 
activities through a combination of milestone payments received pursuant to its strategic alliances, equity 
offerings,  debt  financings,  government  or  other  third-party  funding  and  collaborations,  and  licensing 
arrangements. However, the Company may not receive milestone payments when expected, or at all, and 
the  Company  may  be  unable  to  raise  additional  funds  or  enter  into  such  arrangements  when  needed  on 
favorable terms, or at all, which would have a negative impact on its financial condition and could force 
the Company to delay, limit, reduce or terminate its development programs or commercialization efforts 
or  grant  to  others  rights  to  develop  or  market  product  candidates  that  the  Company  would  otherwise 
prefer  to  develop  and  market  itself.  Failure  to  receive  additional  funding  could  cause  the  Company  to 
cease operations, in part or in full.

Presentation of Financial Information 

The  Company  audited  consolidated  financial  statements  included  herein  as  of  and  for  the  years  ended 
December 31, 2021, 2022 and 2023 have been prepared in accordance with IFRS as issued by the IASB. 

Due to the listing of its ordinary shares on Euronext Paris and in accordance with the European Union’s 
regulation  No.  1606/2002  of  July  19,  2002,  the  Company  also  prepares  and  publishes  its  consolidated 
financial statements in accordance with IFRS as adopted by the European Union (EU). 

All  the  standards  published  by  the  IASB  that  are  mandatorily  applicable  in  the  years  ended  December 
2021, 2022 and 2023 are endorsed by the EU and are mandatorily applicable in the EU. Therefore, the 
Company  audited  consolidated  financial  statements  for  the  years  ended  December  31,  2021,  2022  and 
2023 are compliant with both IFRS as issued by the IASB and IFRS as adopted by the EU.

The  preparation  of  financial  statements  in  accordance  with  IFRS  requires  the  Company  to  make 
significant judgments and estimates which are presented below. See “—Critical Accounting Policies and 
Significant Judgments and Estimates.”

Principal Collaboration and Licensing Agreements of the Company

The Company results of operations are impacted by the terms and conditions of its principal collaboration 
and  licensing  agreements.  For  a  description  of  its  principal  collaboration  and  licensing  agreements,  see 
“Item 10C.—Material Contracts.”

Principal Components of the Company Results of Operations 

Revenue and other income 

The  Company  revenue  and  other  income  mainly  consists  of  revenues  from  collaboration  and  licensing 
agreements and government financing for research expenditure in the form of research tax credits, as well 
as other grants.

Revenue from collaboration and licensing agreements 

The Company currently derives substantially all its revenues from payments pursuant to its licensing and 
collaboration  agreements  notably  with  AstraZeneca  relating  to  monalizumab  and  IPH5201,  Sanofi 
relating  to  IPH6101/SAR'579,  IPH6401/SAR'514  and  IPH62  consisting  of  (i)  upfront  payments,  (ii) 
milestone  payments  based  upon  the  achievement  of  pre-determined  development,  regulatory  and 
commercial events and (iii) research and development fees related to charges for full time equivalents, or 
FTEs, at contracted rates and reimbursement of research and development expenses. 

134

The Company has not generated any significant revenue from product sales since its inception, with the 
exception in 2018, 2019, 2020 and 2021 of Lumoxiti sales, which were previously classified in its half-
year and annual reports in the net income (loss) from distribution agreements during the transition period 
with AstraZeneca (ended September 30, 2020) and as revenue since the fourth quarter of 2020. 

As a result of Innate's decision to terminate the agreement entered into with AstraZeneca in October 2018 
and relating to the license of Lumoxiti (the "Lumoxiti Agreement") in December 2020, a termination and 
transition agreement was negotiated and executed, effective as of June 30, 2021 terminating the Lumoxiti 
Agreement  as  well  as  Lumoxiti  related  agreements  (including  the  supply  agreement,  the  quality 
agreement  and  other  related  agreements)  and  transferring  the  U.S.  marketing  authorization  and 
distribution rights of Lumoxiti back to AstraZeneca, or the Termination and Transition Agreement. Under 
the  Termination  and  Transition  Agreement,  Innate  and  AstraZeneca  delivered  a  notice  to  the  FDA 
requesting that the U.S. marketing authorization be transferred back to AstraZeneca as from October 1, 
2021. AstraZeneca has reimbursed Innate for all Lumoxiti related costs, expenses and benefited net sales. 
As of December 31, 2023, this transfer has now been completed. 

As a consequence of the termination of the Lumoxiti Agreement, the Lumoxiti activity (including sales) is 
presented in the consolidated income statement and the notes to the consolidated financial statements as a 
discontinued  operation  for  the  2023,  2022  and  2021  financial  years  in  accordance  with  IFRS5  "non-
current assets held for sale and discontinued operations." 

The Company ability to generate significant product revenue and to become profitable will depend upon 
its  ability  to  successfully  develop,  obtain  regulatory  approval  for  and  commercialize  any  product 
candidates.  Because  of  the  numerous  risks  and  uncertainties  associated  with  product  development  and 
regulatory  approval,  the  Company  is  unable  to  predict  the  amount,  timing  or  whether  it  will  be  able  to 
obtain product revenue. 

Government financing for research expenditures 

The  Company's  government  financing  for  research  expenditures  consists  of  research  tax  credits  (crédit 
d’impôt recherche) and grants. 

The research tax credit is granted to companies by the French tax authorities in order to encourage them 
to conduct technical and scientific research. Companies demonstrating that they have expenses that meet 
the required criteria, including research expenses located in France or, since January 1, 2005, within the 
EU or in another state that is a party to the agreement in the European Economic Area that has concluded 
a tax treaty with France that contains an administrative assistance clause, receive a tax credit which can be 
used against the payment of the corporate tax due for the fiscal year in which the expenses were incurred 
and  during  the  next  three  fiscal  years,  or,  as  applicable,  can  be  reimbursed  for  the  excess  portion.  The 
expenditures  taken  into  account  for  the  calculation  of  the  research  tax  credit  involve  only  research 
expenses. 

The main characteristics of the research tax credit are: 

•

•

the  research  tax  credit  results  in  a  cash  inflow  to  the  Company,  i.e.,  it  is  used  to  offset  the 
payment  of  corporate  income  tax  the  year  after  the  date  of  its  record  as  a  tax  credit  in  the 
income statement, or is paid directly to the Company from the tax authorities for the portion 
that remains unused, in principle, three years after the fiscal year for which it is determined; 

The  Company's  corporate  income  tax  liability  does  not  limit  the  amount  of  the  research  tax 
credit.  If  the  Company  does  not  pay  any  corporate  income  tax,  the  Company  can  offset  the 
remaining research tax credit the year following its record in the income statement; and 

135

•

the research tax credit is not included in the determination of the corporate income tax. 

When  the  research  tax  credit  is  not  deductible  from  taxes  payable  by  the  Company,  it  is  generally 
reimbursed  by  the  French  government  three  years  after  the  fiscal  year  for  which  it  is  determined. 
However,  since  2011,  companies  that  meet  the  definition  of  small  and  medium  sized  enterprises 
(“SMEs”) according to the European Union criteria are eligible for early reimbursement of their research 
tax credit receivable. The status of SME is lost when the criteria for eligibility are exceeded during two 
consecutive  years.  The  Company  lost  its  SME  status  at  the  end  of  the  2019  fiscal  year  but  has  been 
eligible again since the end of the 2021 financial year. As of December 31, 2023, the company lost again 
the SME status due to two consecutive year with a statutory turnover over €50 000 thousands.

The  Company  has  concluded  that  the  research  tax  credit  meets  the  definition  of  a  government  grant  as 
defined in IAS 20 Accounting for government grants and disclosure of government assistance (IAS 20), 
and that the classification as “Revenue and other income” in its consolidated statement of income (loss) is 
appropriate. 

Innate  also  from  time  to  time  receives  government  grants,  which  are  recognized  in  its  consolidated 
statement  of  income  (loss)  when  comply  with  the  conditions  attached  to  the  grants  and  they  are  non-
repayable grants. 

Operating expenses from continuing operations 

Since  its  inception,  Innate's  operating  expenses  have  consisted  primarily  of  research  and  development 
expenses and general and administration expenses. 

Following the transfer back of the U.S. marketing authorization to AstraZeneca linked to the Termination 
and  Transition  Agreement  (from  October  1,  2021),  selling  expenses  relating  to  Lumoxiti  activities  are 
presented  as  discontinued  operations  since  December  31,  2021.  The  2020  and  2019  comparatives  have 
been  restated  compared  to  previous  publications,  in  accordance  with  the  same  standard  (see 
"Discontinued Operations" below).

Research and development expenses 

The  Company  engages  in  substantial  research  and  development  efforts  to  develop  innovative  product 
candidates. Research and development expenses consist primarily of: 

•

•

•

•

personnel costs, including salaries, related benefits and share-based compensation, for Innate's 
employees engaged in scientific research and development functions; 

cost  of  third-party  contractors  and  academic  institutions  involved  in  preclinical  studies  or 
clinical trials that the Company may conduct, or third-party contractors involved in field trials; 

purchases  of  biological  raw  materials,  real  estate  leasing  costs  as  well  as  conferences  and 
travel costs; and 

certain  other  expenses,  such  as  expenses  for  use  of  laboratories  and  facilities  for  Innate's 
research and development activities as well as depreciation and amortization. 

Innate's  research and development efforts are focused on its existing product candidates and preclinical 
programs, including the advancement of its lead product candidates, monalizumab, lacutamab. Its direct 
research and development expenses consist principally of external costs associated with subcontracting of 
preclinical  and  clinical  operations  to  third  parties,  which  Innate  tracks  on  a  program-by-program  basis. 
The  Company  also  uses  its  employee  and  infrastructure  resources  across  multiple  research  and 
development programs, and does not track these indirect expenses on a program-by-program basis. 

136

Research  and  development  costs  are  expensed  as  incurred.  Costs  for  certain  activities  are  recognized 
based  on  an  evaluation  of  the  progress  to  completion  of  specific  tasks  using  data  such  as  information 
provided  to  Innate  Pharma  by  its  vendors  and  analyzing  the  progress  of  its  preclinical  studies  or  other 
services  performed.  Significant  judgment  and  estimates  are  made  in  determining  the  accrued  expense 
balances  at  the  end  of  any  reporting  period.  Non-refundable  advance  payments  for  research  and 
development goods or services to be received in the future from third parties are deferred and capitalized. 
The capitalized amounts are expensed as the related goods are delivered or the services are performed.

Research and development activities are central to Innate's business. As product candidates in later stages 
of  clinical  development generally have higher development costs than those in earlier stages of clinical 
development, primarily due to the increased size and duration of later-stage clinical trials, the Company 
expects that its research and development costs will increase in the foreseeable future. Such cost increases 
are expected to occur as the Company conducts existing clinical trials and initiates future clinical trials, 
manufactures  pre-commercial  clinical  trial  and  preclinical  study  materials,  expands  its  research  and 
development  efforts,  seeks  regulatory  approvals  for  its  product  candidates  that  successfully  complete 
clinical trials, accesses and develops additional technologies and hires additional personnel to support its 
research and development efforts. 

The Company cannot determine with certainty the duration and total costs of its future clinical trials of its 
product candidates or if, when, or to what extent it will generate revenues from the commercialization and 
sale of any of its product candidates, or those of its collaborators, that might obtain regulatory approval. 
The  Company  may  never  succeed  in  achieving  regulatory  approval  for  any  product  candidates.  The 
duration,  costs and timing  of clinical trials and development of its product candidates will depend on  a 
variety of factors, including: 

•

•

•

•

•

the scope, rate of progress and expense of its ongoing clinical trials as well as any additional 
preclinical  studies,  clinical  trials  conducted  by  its  collaborators  and  other  research  and 
development activities; 

clinical trial and preclinical study results; 

the terms and timing of regulatory approvals; 

the  expense  of  filing,  maintaining,  prosecuting,  defending  and  enforcing  patent  claims  and 
other intellectual property rights; and 

the  ability  to  market,  commercialize  and  achieve  market  acceptance  for  any  products  that 
receive regulatory approval.

A  change  in  the  outcome  of  any  of  these  variables  with  respect  to  the  development  of  monalizumab, 
lacutamab or any other product candidate or preclinical program that the Company is developing or could 
develop  in  the  future  could  mean  a  significant  change  in  the  costs  and  timing  associated  with  the 
development of such product candidates or preclinical programs. For example, if the FDA, the EMA or 
another regulatory authority were to require Innate to conduct preclinical studies and clinical trials beyond 
those  that  it  currently  anticipates  will  be  required  for  the  completion  of  clinical  development,  or  if  the 
Company  experiences  significant  delays  in  enrollment  in  any  clinical  trials,  the  Company  could  be 
required  to  spend  significant  additional  financial  resources  and  time  on  the  completion  of  clinical 
development.  For  a  discussion  of  the  risks  associated  with  completing  the  development  projects  on 
schedule, see “Risk Factors—Risks Related to the Development of the Product Candidates.” 

General and administrative expenses 

General and administrative expenses consist primarily of personnel costs and share-based compensation 
for personnel other than research and development staff. Selling, general and administrative expenses also 

137

consist  of  fees  for  professional  services,  mainly  related  to  audit,  IT,  accounting,  recruitment  and  legal 
services, communication and travel costs, real-estate leasing costs, office furniture and equipment costs, 
allowance for amortization and depreciation, director’s attendance fees and insurance costs and overhead 
costs, such as postal and telecommunications expenses. 

Net financial income (loss) 

The  financial  income  (loss)  primarily  consists  of  realized  and  unrealized  foreign  exchange  gains  and 
losses  primarily  related  to  the  purchase  of  services  as  well  as  deposit  accounts  denominated  in  U.S. 
dollars and gains and losses and interest received in relation to cash and cash equivalents that have been 
deposited  in  cash  accounts,  short-term  fixed  deposits  and  short-term  highly  liquid  investments  with 
original maturities of three months or less. Thus, the Company's cash and cash equivalents generated €1.9 
million of interest income in the financial year ended December 31, 2023. Innate expects to continue this 
investment philosophy in the future.

Net result from discontinued operations 

Pursuant  to  the  Termination  and  Transition  Agreement,  in  the  year  ended  December  31,  2020  results 
announcement,  the  Company  reported  a  contingent  liability  of  up  to  $12.8  million  in  its  consolidated 
financial  statements,  which  was  related  to  the  splitting  of  certain  manufacturing  costs.  As  part  of  the 
Termination and Transition Agreement, Innate and AstraZeneca agreed to split these manufacturing costs, 
and Innate paid $6.2 million (€5.5 million as of December 31, 2021) to AstraZeneca on April 30, 2022. 

As a consequence of the termination of the Lumoxiti Agreement, the Lumoxiti activity (including sales) is 
presented in the consolidated income statement and the notes to the consolidated financial statements as a 
discontinued  operation  for  the  2023,  2022  and  2021  financial  years  in  accordance  with  IFRS5  "non-
current assets held for sale and discontinued operations." Therefore, the income statement for the years 
ended December 31, 2020 and subsequent years have been prepared with the Lumoxiti activity (including 
sales)  as  a  discontinued  operation  for  the  2020  and  subsequent  financial  years  in  accordance  with  the 
same IFRS standard.

Impairment of intangible assets 

The  Group  assesses  at  the  end  of  each  reporting  period  whether  there  is  an  indication  that  intangible 
assets,  property  and  equipment  may  be  impaired.  If  any  indication  exists,  the  Group  estimates  the 
recoverable amount of the related asset.

Whether or not there is any indication of impairment, intangible assets not yet available for use are tested 
for impairment annually by comparing their carrying amount with their recoverable amount. 

Pursuant to IAS 36—Impairment of Assets, criteria for assessing indication of loss in value may notably 
include  performance  levels  lower  than  forecast,  a  significant  change  in  market  data  or  the  regulatory 
environment,  or  obsolescence  or  physical  damage  of  the  asset  not  included  in  the  amortization/
depreciation schedule. The recognition of an impairment loss alters the amortizable/depreciable amount 
and potentially, the amortization/depreciation schedule of the relevant asset. 

As  of  December  31,  2022,  impairment  of  intangible  assets  consisted  of  the  full  depreciation  of 
avdoralimab rights for an amount of €41.0 million, following the Company's decision to stop avdoralimab 
development in bullous phemphigoid ("BP") indication in inflammation following a decision taken by a 
sponsor to stop the Phase 2 clinical trial in said indication during the fourth quarter of 2022.

Proceeds related to monalizumab. 

Revenues related to monalizumab result from the partial recognition of the $250.0 million non-refundable 
upfront  payment  and the $100.0 million milestone resulting from the exercise of the option received in 
June 2015 and October 2018 from AstraZeneca. The additional payment of $50.0 million (€47.7 million) 
received from AstraZeneca in December 2020 triggered by the dosing of the first patient in the Phase 3 
trial evaluating monalizumab was treated in full as a collaboration commitment ("collaboration liability" 
in the consolidated balance sheet) in view to the commitment linked to the agreement for the Phase 1/2 
(co-financing)  and  Phase  3  studies  (amendment  signed  in  September  2020).  For  more  information,  see 
Note  1.1  to  the  consolidated  financial  statements  are  included  as  part  of  this  Annual  Report. 
Consequently, this additional payment has no impact on the transaction price. 

In addition to these amounts, AstraZeneca made an additional payment of $50.0 million (€47.7 million) in 
June 2022, triggered by the treatment of the first patient in a second Phase 3 trial evaluating monalizumab 
in  April  2022.  This  additional  payment  has  been  treated  as  a  collaboration  commitment  ("collaboration 
liability" in the consolidated balance sheet) for an amount of $36.0 million (€34.3 million) in view to the 
contractual  commitment  linked  to  the  Phase  1/2  studies  (co-funding  under  the  initial  contract).  The 
remaining  $14.0  million  was  treated  as  a  change  in  estimate  of  the  transaction  price,  recognized  in  the 
income statement in line with the progress of the Phase 1/2 studies. 

Revenue related to monalizumab decreased by €12.9 million, to €9.5 million for the year ended December 
31,  2023,  as  compared  to  €22.4  million  for  the  year  ended  December  31,  2022.  This  €12.9  million 
decrease mainly resulted from to the increase, in the first half of 2022, in the transaction price of €13.4 
million ($14.0 million) triggered by the launch of the PACIFIC-9 Phase 3 trial on April 28, 2022. As a 
reminder, this increase in the transaction price led to the recognition of additional income of €12.6 million 
in the income related to the monalizumab agreement for 2022. As of December 31, 2023, the amount not 
recognized  as  revenue  amounted  to  €5.2  million,  and  is  presented  in  full  under  "Current  contract 
liabilities" given the maturity of the Phase 1/2 trials.

Proceeds related to IPH5201. Revenue related to IPH5201 for the year ended December 31, 2023 is $0.0 
compared  with  $5.0  million  (€4.7  million)  for  the  year  2022.  This  revenue  related  to  the  milestone 
payment  received  from  AstraZeneca  following  the  signature  on  June  1,  2022  of  an  amendment  to  the 
initial  contract  signed  in  October  2018.  This  amendment  sets  the  terms  of  the  collaboration  following 
AstraZeneca’s  decision  to  advance  IPH5201  to  a  Phase  2  study.  The  Company  will  conduct  the  study. 
Both  parties  will  share  the  external  cost  related  to  the  study  and  incurred  by  the  Company  and 
AstraZeneca will provide products necessary to conduct the clinical trial.  For more information on this 
amendment,  see  Note  1.1  to  the  consolidated  financial  statements  are  included  as  part  of  this  Annual 
Report. 

Proceeds  related  to  collaboration  and  option  agreement  related  to  four  to-be-agreed  upon  molecules 
(preclinical molecules). 

During the first half of 2022, the Company received from AstraZeneca a notice that it will not exercise its 
option to license the four preclinical programs covered in the "Future Programs Option Agreement." This 
license option was part of the 2018 multi-term agreement between AstraZeneca and the Company under 
which  the  Company  had  received  an  upfront  payment  of  $20.0  million  (€17.4  million).  As  the  rights 
related to these four preclinical programs have been returned to the Company, the entire upfront payment 
of $20.0 million (€17.4 million) has been recognized as revenue as of June 30, 2022. 

141

 
Invoicing of research and development costs - IPH5201. 

Pursuant  to  the  Company's  agreements  with  AstraZeneca,  research  and  development  costs  related  to 
IPH5201  in  connection  with  preclinical  work  are  fully  borne  by  AstraZeneca,  in  accordance  with  the 
initial 2018 agreement. These costs were re-invoiced on a quarterly basis. Following the signature on June 
1,  2022  of  an  amendment  to  the  initial  agreement  signed  in  October  2018  specifying  the  terms  of  the 
collaboration following the decision to advance IPH5201 to a Phase 2 study, the parties are committed to 
sharing the external costs of the study incurred by the Company and AstraZeneca will provide products 
necessary to conduct the clinical trial.

Revenue from invoicing of research and development costs for the year ended December 31, 2023 was 
€1.2  million  compared  to  €1.4  million  for  the  year  ended  December  31,  2022,  or  a  decrease  of  €  0.2 
million. 

Proceeds related to Sanofi 2016 agreement. 

Revenues  under  the  collaboration  and  license  agreement  signed  with  Sanofi  in  2016  amounted  to  €2.0 
million for the year ended December 31, 2023 as compared to €4.0 million for the year ended December 
31, 2022. The Company announced that, in June 2023, the first patient was dosed in a Sanofi-sponsored 
Phase  1/2  clinical  trial  evaluating  IPH6401/SAR'514  in  relapsed  or  refractory  Multiple  Myeloma.  As 
provided by the licensing agreement signed in 2016, Sanofi made a milestone payment of €2.0 million, 
fully  recognized  in  revenue  since  June  2023.  This  amount  was  received  by  the  Company  on  July  21, 
2023. As a reminder, the revenue recognized in 2022 resulted from Sanofi's decision to advance IPH6401/
SAR'514 towards regulatory preclinical studies for a new investigational drug. This decision triggered a 
milestone  payment  of  €3.0  million  fully  recognized  in  revenue.  This  amount  was  received  by  the 
Company on September 9, 2022. 

Proceeds related to Sanofi 2022 agreement

On  December  19,  2022,  the  Company  announced  that  it  had  entered  into  a  research  collaboration  and 
license agreement with Genzyme Corporation, a wholly-owned subsidiary of Sanofi (“Sanofi”) pursuant 
to  which  the  Company  granted  Sanofi  an  exclusive  license  on  the  Innate  Pharma's  B7-H3  ANKET® 
program  and  options  on  two  additional  targets.  On  January  25,  2023,  the  Company  announced  the 
expiration of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976 
and  the  effectiveness  of  the  licensing  agreement  as  of  January  24,  2023.  Consequently,  the  Company 
received  an  upfront  payment  of  €25.0  million  in  March  2023,  including  €18.5  million  relating  to  the 
exclusive license, €1.5 million relating to the research work and €5.0 million relating to the two additional 
targets options.

The Company considers that the license to the B7-H3 technology is a right to use the intellectual property 
granted  exclusively  to  Sanofi  as  from  the  effective  date  of  the  agreement.  As  such,  the  €18.5  million 
upfront payment relating to the exclusive license has been fully recognized in revenue since June 2023. 

The  Company  will  provide  collaborative  research  services  to  Sanofi  for  an  initial  estimated  three  years 
period as from the effective date of the collaboration, i.e., January 24, 2023. During this period, Sanofi 
and Innate will collaborate and work on research activities as defined in the work program described in 
the agreement. Consequently, the corresponding upfront payment of €1.5 million will be recognized on a 
straight-line basis over the duration of the research services that the Company has agreed to carry out. As 
a  result,  a  €0.4  million  has  been  recognized  in  revenue  as  of  December  31,  2023,  and  amounts  not 
recognized  in  revenue  are  classified  as  deferred  revenue—current  portion  equal  to  €0.3  million  and 
deferred revenue—non-current portion  equal to €0.8 million. 

Under the terms of this agreement, the Company has also granted two exclusive options, exercisable no 
later than three years after the effective date, for exclusive licenses to Innate's intellectual property for the 

142

research,  development,  manufacture  and  commercialization  of  NKCEs  specifically  targeting  two 
preclinical molecules. The Company considers that the option to acquire an exclusive license provide a 
material right to Sanofi that it would not receive without entering into this agreement. The Company will 
recognize  the  related  revenues  either  at  the  reporting  date  or  three  years  after  the  effective  date. 
Consequently,  the  €5.0  million  initial  payment  relating  to  these  options  was  recognized  in  deferred 
revenue—non-current portion as of June 30, 2023.

On December 19, 2023, the Company announced that Sanofi had exercised an option for one of the two 
preclinical molecules. As a consequence, the Company recognized related income of €2.5 million as of 
December 31, 2023. 

This  option  exercise  also  resulted  in  a  milestone  payment  of  €15.0  million,  including  €13.3  million  in 
respect  of  the  exclusive  license,  which  was  fully  recognized  in  income  as  of  December  31,  2023,  and 
€1.7  million  in  respect  of  research  services  to  be  carried  out  by  the  Company.  Sanofi  and  Innate  will 
collaborate  and  work  on  the  research  activities  defined  in  the  contractual  work  program.  Consequently, 
the  corresponding  initial  payment  of  €1.7  million  will  be  recognized  on  a  straight-line  basis  over  the 
duration of the research work that the Company has agreed to carry out. This work had not yet begun as 
of December 31, 2023. In this respect, no revenue has been recognized in the income statement, and the 
amount  of  €1.7  million  is  presented  under  current  contract  liabilities  (€0.4  million)  and  non-current 
contract liabilities (€1.3 million). 

Under the terms of the agreement, Sanofi still retains a license option for a third preclinical molecule.

Proceeds related to Takeda agreement

On April 3, 2023, the Company announced that it has entered into an exclusive license agreement with 
Takeda  under  which  Innate  granted  Takeda  exclusive  worldwide  rights  to  research  and  develop  ADCs 
using a panel of selected Innate antibodies against an undisclosed target, with a primary focus in Celiac 
disease.  Takeda  will  be  responsible  for  the  future  development,  manufacture  and  commercialization  of 
any potential products developed using the licensed antibodies. As such, the Company considers that the 
license granted is a right to use the relevant intellectual property, which is granted fully and perpetually to 
Takeda. The agreement does not stipulate that Innate's activities will significantly affect the intellectual 
property granted during the life of the agreement. Consequently, the $5.0 million (or €4.6 million) initial 
payment, received by the Company in May 2023, was fully recognized in revenue since June 30, 2023.

Government financing for research expenditures 

Government funding for research expenditures increased by €1.7 million, or 21.08%, to €9.7 million for 
the year ended December 31, 2023, as compared to €8.0 million for the year ended December 31, 2022. 
As  a  reminder,  the  2022  research  tax  credit  included  a  reduction  of  €1.3  million  related  to  a  provision 
following the tax inspection carried out in 2022 by the French tax authorities. This provision was based 
on estimated amounts and adjustments not disputed by the Company and has been increased in 2023 for 
€0.1 million.

The table below details government funding for research expenditures for the years ended December 31, 
2022 and 2023.

(1)  2022 Total Research and Development expenses excludes €41.0 million of avdoralimab impairment. 

Research  and  development  expenses  from  continuing  operations increased  by  €4.4  million,  or  8.4%,  to 
€56.0 million for the year ended December 31, 2023, as compared to research and development expenses 
of €51.7 million for the year ended December 31, 2022. This increase over the period is mainly due to an 
increase  in  direct  research  and  development  expenses  of  €2.7  million  over  the  period  due  to  the 
significant  increase  in  expenses  relating  to  pre-clinical  development  programs,  partly  offset  by  the 
decrease  in  expenses  relating  to  clinical  programs.  Research  and  development  expenses  represented  a 
total of 75.4% and 69.7% of operating expenses before impairment for years ended December 31, 2023 
and  December  31,  2022,  respectively.  Indirect  expenses  increased  by  €1.7  million  mainly  in  personnel 
expenses and amortization and depreciation.

Direct  research  and  development  expenses increased  by  €2.7  million,  or  9.8%,  to  €30.2  million  for  the 
year  ended  December  31,  2023,  as  compared  to  direct  research  and  development  expenses  of  €27.5 
million for the year ended December 31, 2022. This increase is mainly due to a €3.2 million increase in 
expenses related to preclinical development programs relating notably to the ADC field, partly offset by a 
€0.5  million  decrease  in  expenses  related  to  the  Company's  clinical  programs.  This decrease  in  clinical 
programs expenses mainly results from a €0.4 million decrease in expenses relating to the monalizumab 
program,  a  €0.2  million  decrease  in  expenses  relating  to  the  avdoralimab  program  and  a  €0.2  million 
decrease  in  expenses  relating  to  the  lacutamab  program,  partly  offset  by  a  €0.7  million  increase  in 
expenses related to the growth in IPH5201 phase 2 trials patient recruitment.

Also, as of December 31, 2023, the collaboration liabilities relating to monalizumab and the agreements 
signed with AstraZeneca in April 2015, October 2018 and September 2020 amounted to €52.7 million, as 
compared to collaborations liabilities of €63.2 million as of December 31, 2022. This decrease of €10.5 
million mainly results from (i) net repayment of €8.4 million during year 2023 to AstraZeneca linked to 
the Monalizumab cofinancing program, including phase 3 trial INTERLINK-1 launched in October 2020 
and  PACIFIC-9  launched  in  April  2022,  and  (ii)  the  decrease  of  the  collaboration  commitment 

145

 
 
 
("collaboration  liabilities"  in  the  consolidated  statements  of  financial  position)  for  an  amount  of  €2.0 
million linked to the Euro-dollar parity exchange rate variation.

Personnel and other expenses allocated to research and development increased by €1.7 million, or 6.9%, 
to €25.8 million for the year ended December 31, 2023, as compared to an amount of €24.2 million for 
the  year  ended  December  31,  2022.  This  increase  is  due  to  the  (i)  €0.7  million  increase  in  staff  costs 
allocated to research and development, of which €0.5 million in personnel expenses and €0.2 million in 
share-based  payment  expenses,  (ii)  increase  of  €1.0  million  in  depreciation  and  amortization.  The  line 
item is mainly composed of the amortization of the monalizumab, IPH5201 intangible assets.

As  of  December  31,  2023,  the  Company  had  140  employees,  including  Leadership  Team  members,  in 
research and development functions, compared to 155 as of December 31, 2022.

General and administrative expenses 

General and administrative expenses from continuing operations decreased by €4.1 million, or 18.5%, to 
€18.3  million  for  the  year  ended  December  31,  2023,  as  compared  to  €22.4  million  for  the  year  ended 
December 31, 2022. General and administrative expenses represented a total of 24.6% and 30.3% of our 
total  operating  expenses  before  impairment  for  the  years  ended  December  31,  2023  and  2022, 
respectively.

(1) Other  expenses  are  related  to  intellectual  property,  maintenance  costs  for  laboratory  equipment  and  our  headquarters,  depreciation  and 

amortization and other general and administrative expenses.

Personnel expenses, which includes the compensation paid to our employees and consultants, decreased 
by  €1.4  million,  or  13.6%,  to  €8.8  million  for  the  year  ended  December  31,  2023,  as  compared  to 
personnel expenses of €10.2 million for the year ended December 31, 2022. This decrease mainly results 
from a decrease in wages of €1.2 million as well as a decrease of €0.2 million in share-based payment 
expenses  mainly  explained  by  the  decrease  of  employees.  As  of  December  31,  2023,  we  had 
39  employees,  including  Leadership  Team  members,  in  general  and  administrative  functions,  as 
compared to 55 as of December 31, 2022.

Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal and hiring 
services.  These  expenses  decreased  by  €1.3  million,  or  31.5%,  to  €2.9  million  for  the  year  ended 
December 31, 2023, as compared to an amount of €4.2 million for the year ended December 31, 2022. 
This decrease mainly results from operating efficiency measures, which led to a reduction in the number 
of new hires, and use of external communication and consulting services.

146

 
 
 
Other  general  and  administrative  expenses  relate  to  intellectual  property,  depreciation  and  amortization 
and other general, administrative expenses. These expenses decreased by €1.4 million or 17.9% to €6.5 
million  for  the  year  ended  December  31,  2023,  as  compared  to  an  amount  of  €8.0  million  for  the  year 
ended December 31, 2022. 

This  decrease  related  notably  to  savings  (reduction  in  office  space)  and  a  reclassification  of  R&D 
laboratory support costs (maintenance, supplies, depreciation of R&D equipment) for 1.0 million euros in 
R&D.

Impairment of intangible assets

As a reminder, for the year ended December 31, 2022, impairment of intangible assets results from full 
impairment  of  anti-C5aR  rights  acquired  from  Novo/Nordisk  A/S  (avdoralimab  intangible  asset)  for  an 
amount of €41.0 million. During the fourth quarter of 2022, the Company was informed by the sponsor of 
the Phase 2 clinical trial evaluating avdoralimab in inflammation in bullous pemphigoid ("BP") indication 
of  its  decision  to  stop  said  trial.  Consequently,  the  Company  decided  in  December  2022  to  stop  the 
development of avdoralimab in BP indication in inflammation, only indication supporting the recoverable 
amount of the asset as of December 31, 2021 (as well that as of June 30, 2022). Without any new event 
during year ended December 31, 2023, the impairment has not been reassessed. 

Financial income (loss), net 

The net financial result increased by €5.6 million, to a €5.1 million profit for the year ended December 
31, 2023, as compared to a €0.5 million loss for the year ended December 31, 2022. This change mainly 
results from interest income on financial investments (net gain of €2.5 million in 2023), the change in the 
fair value of certain financial instruments (net gain of €1.6 million in 2023 as compared to a net loss of 
€1.6  million  in  2022)  and  a  net  foreign  exchange  gain  of  €0.9  million  in  2023  as  compared  to  a  net 
foreign exchange gain of €0.8 million in 2022.

The  table  below  presents  the  components  of  our  net  financial  result  for  the  years  ended  December  31, 
2022 and 2023:

For the years ended December 31, 2022 and 2023, the foreign exchange gains and losses mainly result 
from the variance of the exchange rate between the Euro and the U.S. dollar on U.S. dollar-denominated 
cash  and  cash  equivalents,  short-term  investments  and  financial  assets.  For  instruments  for  which  the 
valuation may be subject to certain events, the Company has ensured that no such events have occurred a 
of December 31, 2023.

Net result from discontinued operations 

Subsequently to the Termination and Transition Agreement, operations related to Lumoxiti are presented 
as a discontinued operation as of October 1, 2021. 

As  a  consequence,  the  Lumoxiti  activity  (including  sales)  is  presented  in  the  consolidated  income 
statement and the notes to the consolidated financial statements as a discontinued operation for the 2021 
financial year in accordance with IFRS5 "non-current assets held for sale and discontinued operations." 

Thus, the net result from discontinued operations relating to Lumoxiti represents a net loss of €0.1 million 
as compared to a net loss nil for the years ended December 31, 2022 and 2023, respectively, presented as

Revenues from collaboration and licensing agreements 

Revenue  from  collaboration  and  licensing  agreements  from  continuing  operations  increased  by  €37.5 
million,  to  €49.6  million  for  the  year  ended  December  31,  2022,  as  compared  to  revenue  from 
collaboration and licensing agreements of €12.1 million for the year ended December 31, 2021. Revenue 
from  collaboration  and  licensing  agreements  mainly  resulted  from  the  agreements  with  AstraZeneca 
signed in April 2015 and October 2018, as well as the agreement signed with Sanofi in 2016. Revenue 
from collaboration and licensing agreements is set forth in the table below.

Proceeds related to monalizumab. Revenue related to monalizumab increased by €14.9 million, to €22.4 
million for the year ended December 31, 2022, as compared to €7.5 million for the year ended December 
31,  2021.  This  €14.9  million  increase  mainly  results  from  the  transaction  price  increase  related  to  the 
additional payment of $50.0 million (€47.7 million) made by AstraZeneca in June 2022 and triggered by 
the treatment of the first patient in a second Phase 3 trial “PACIFIC-9” evaluating monalizumab in April 
2022.  This  additional  payment  has  been  treated  as  an  increase  of  the  collaboration  commitment 
("collaboration  liabilities"  in  the  consolidated  statements  of  financial  position)  for  an  amount  of  $36.0 
million (€34.3 million) in connection to the Phase 3 study co-funding commitment made by the Company 
and  notified  to  AstraZeneca  in  July  2019.  The  remaining  amount  of  $14.0  million  (€13.4  million)  has 

151

 
 
 
 
 
 
been treated as an increase of the transaction price, recognized in the income statement in line with the 
progress  of  the  Phase  1/2  studies.  This  increase  in  the  transaction  price  generated  a  €12.6  million 
favorable cumulative adjustment in the revenue related to monalizumab agreements over the period. As of 
December  31,  2022,  the  deferred  revenue  related  to  monalizumab  amounted  to  €14.5  million  (€6.6 
million  as  “Deferred  revenue—Current  portion”  and  €7.9  million  as  “Deferred  revenue—Non-current 
portion”). 

Proceeds related to IPH5201. Revenue related to IPH5201 for the year ended December 31, 2022 is €4.7 
million  and  results  from  the  entire  recognition  in  revenue  of  the  $5.0  million  (€4.7  million)  milestone 
payment  received  from  AstraZeneca  following  the  signature  on  June  1,  2022  of  an  amendment  to  the 
initial  contract  signed  in  October  2018.  This  amendment  sets  the  terms  of  the  collaboration  following 
AstraZeneca’s  decision  to  advance  IPH5201  to  a  Phase  2  study.  The  Company  will  conduct  the  study. 
Both  parties  will  share  the  external  cost  related  to  the  study  and  incurred  by  the  Company  and 
AstraZeneca will provide products necessary to conduct the clinical trial. 

Proceeds  related  to  collaboration  and  option  agreement  related  to  four  to-be-agreed  upon  molecules 
(preclinical molecules). During the first half of 2022, the Company received from AstraZeneca a notice 
that it will not exercise its option to license the four preclinical programs covered in the "Future Programs 
Option Agreement." This license option was part of the 2018 multi-term agreement between AstraZeneca 
and  the  Company  under  which  the  Company  had  received  an  upfront  payment  of  $20.0  million  (€17.4 
million). As the rights related to these four preclinical programs have been returned to the Company, the 
entire  upfront  payment  of  $20.0  million  (€17.4  million)  has  been  recognized  as  revenue  as  of  June  30, 
2022. 

Invoicing  of  research  and  development  costs  -  IPH5201.  Pursuant  to  the  Company's  agreements  with 
AstraZeneca, research and development costs related to IPH5201 in connection with preclinical work are 
fully borne by AstraZeneca, in accordance with the initial 2018 agreement. These costs were re-invoiced 
on a quarterly basis. Following the signature on June 1, 2022 of an amendment to the initial agreement 
signed  in  October  2018  specifying  the  terms  of  the  collaboration  following  the  decision  to  advance 
IPH5201 to a Phase 2 study, the parties are committed to sharing the external costs of the study incurred 
by the Company and AstraZeneca will provide products necessary to conduct the clinical trial.

Revenue from invoicing of research and development costs for the year ended December 31, 2022 was 
€1.4  million  compared  to  €1.6  million  for  the  year  ended  December  31,  2021,  or  a  decrease  of  €  0.2 
million. 

Proceeds  related  to  Sanofi  2016  agreement.  Revenues  under  the  collaboration  and  license  agreement 
signed with Sanofi in 2016 amounted to €4.0 million for the year ended December 31, 2022 as compared 
to  €3.0  million  for  the  year  ended  December  31,  2021.  During  the  period,  the  Company  announced, 
notably, the decision taken by Sanofi to advance IPH6401/SAR'514 towards regulatory preclinical studies 
for  a  new  investigational  drug.  This  decision  triggered  a  milestone  payment  of  €3.0  million  fully 
recognized in revenue. This amount was received by the Company on September 9, 2022. 

Government financing for research expenditures 

Government funding for research expenditures decreased by €4.6 million, or 36.2%, to €8.0 million for 
the year ended December 31, 2022, as compared to €12.6 million for the year ended December 31, 2021. 
This change is mainly due to a €2.4 million decrease in the research tax credit which is mainly due to (i) a 
decrease in eligible expenses in the research tax credit calculation and (ii) a provision following the tax 
inspection carried out in 2022 by the French tax authorities and recognized as a deduction from the 2022 
research  tax  credit.  This  provision  is  based  on  estimated  amounts  and  adjustments  not  disputed  by  the

year for an amount of €9.2 million from which is subtracted (ii) a provision amounting to €1.3 million following the tax inspection carried 
out in 2022 by the French tax authorities and relating to the 2019 and 2020 financial years as well as to the research tax credit and the 
accuracy of its calculation for the 2018 to 2018 financial years 2020. This provision was recognized as a deduction from the 2022 research 
tax credit, based on estimated amounts and adjustments not disputed by the Company. On March 3, 2023, the Company received from the 
tax  authorities  the  rectification  proposal,  confirming  the  amount  of  the  provision  recognized  on  the  amounts  of  the  rectifications  not 
disputed by the Company.

(2)  As a reminder, the total amount of grants recognized in the income statement as of December 31, 2021 included an amount of €2.0 million 
representing the first tranche received (€1.4 million) and a remaining amount to be received (€0.6 million) related to the BPI financing 
contract signed in August 2020 as a part of the program set up by the French government to help develop a therapeutic solution with a 
preventive  or  curative  aim  against  COVID-19.  As  of  December  31,  2021,  the  financing  is  considered  by  the  Company  to  be  non-
refundable,  in  accordance  with  the  terms  of  the  agreement,  in  light  of  the  technical  and  commercial  failure  of  the  project  based  on  the 
results of the Phase 2 "Force" trial evaluating avdoralimab in COVID-19, published in July 6, 2021. The remaining amount of €0.6 million 
has been received by Company in January and May, 2022. 

The research tax credit is calculated as 30% of the amount of research and development expenses, net of 
grants received, eligible for the research tax credit for the fiscal year.

Research  and  development  expenses  from  continuing  operations  increased  by  €4.7  million,  or  9.9%,  to 
€51.7 million for the year ended December 31, 2022, as compared to research and development of €47.0 
million for the year ended December 31, 2021. This increase over the period is mainly due to an increase 
in indirect research and development expenses resulting from an increase of €3.9 million in personnel and 
other  expenses  in  line  with  (i)  an  increase  in  scientific  and  non  scientific  fees  related  to  research  and 
development operations. In addition, direct research and development expenses increased by €0.8 million 
over the period due to the significant increase in expenses relating to non-clinical development programs, 
partly  offset  by  the  decrease  in  expenses  relating  to  clinical  programs.  Research  and  development 
expenses  represented  a  total  of  69.7%  and  64.8%  of  operating  expenses  before  impairment  for  years 
ended December 31, 2022 and December 31, 2021, respectively. 

Direct  research  and  development  expenses  increased  by  €0.8  million,  or  2.8%,  to  €27.5  million  for  the 
year  ended  December  31,  2022,  as  compared  to  direct  research  and  development  expenses  of  €26.7 
million for the year ended December 31, 2021. This increase is mainly due to: (i) a €5.0 million increase 
in expenses related to preclinical development programs relating notably to IPH6501, partly offset by a 
€4.3  million  decrease  in  expenses  related  to  the  Company's  clinical  programs.  This  decrease  in  clinical 
programs  expenses  mainly  results  from  a  €2.9  million  and  decrease  in  expenses  relating  to  the 
avdoralimab program and a €2.4 million decrease in expenses relating to the lacutamab program, partly 
offset by a €1.1 million increase in expenses related to IPH5201. 

Also, as of December 31, 2022, the collaboration liabilities relating to monalizumab and the agreements 
signed with AstraZeneca in April 2015, October 2018 and September 2020 amounted to €63.2 million, as 
compared to collaborations liabilities of €40.4 million as of December 31, 2021. This increase of €22.8 
million mainly results from the additional payment of $50.0 million (€47.7 million) made by AstraZeneca 
in  June  2022  and  triggered  by  the  treatment  of  the  first  patient  in  a  second  Phase  3  trial  “PACIFIC-9” 
evaluating  monalizumab  in  April  2022.  This  additional  payment  has  been  treated  as  an  increase  of  the 
collaboration commitment ("collaboration liabilities" in the consolidated statements of financial position) 
for an amount of $36.0 million (€34.3 million) in connection to the Phase 3 study co-funding commitment 
made  by  the  Company  and  notified  to  AstraZeneca  in  July  2019.  This  increase  was  partially  offset  by 

154

 
 
 
payments made in 2022 to AstraZeneca related to the co-funding of the monalizumab program, including 
the Phase 3 INTERLINK-1 and PACIFIC-9 trials. 

Personnel and other expenses allocated to research and development increased by €3.9 million, or 19.2%, 
to €24.2 million for the year ended December 31, 2022, as compared to an amount of €20.3 million for 
the year ended December 31, 2021. This increase is due to (i) a €3.0 million increase in other expenses 
related to the €1.3 million increase in non-scientific fees and the €1.0 million increase in scientific fees 
allocated to  research  and development, mainly explained by the increase in the use of external medical 
and  regulatory  experts,  as  well  as  (ii)  the  €1.2  million  increase  in  staff  costs  allocated  to  research  and 
development.  This  increase  is  mainly  explained  by  the  increase  of  €1.7  million  share-based  payments 
expenses. 

As  of  December  31,  2022,  the  Company  had  152  employees  in  research  and  development  functions, 
compared to 148 as of December 31, 2021.

General and administrative expenses 

General and administrative expenses from continuing operations decreased by €3.1 million, or 12.1%, to 
€22.4  million  for  the  year  ended  December  31,  2022,  as  compared  to  €25.5  million  for  the  year  ended 
December 31, 2021. General and administrative expenses represented a total of 30.3% and 35.2% of our 
total  operating  expenses  before  impairment  for  the  years  ended  December  31,  2022  and  2021, 
respectively.

Personnel expenses, which includes the compensation paid to our employees and consultants, decreased 
by  €0.7  million,  or  6.0%,  to  €10.2  million  for  the  year  ended  December  31,  2022,  as  compared  to 
personnel expenses of €10.9 million for the year ended December 31, 2021. This decrease mainly results 
from  a  decrease  in  wages  of  €0.6  million,  mainly  resulting  from  restructuring  costs  and  higher  annual 
bonuses level  in 2021 as compared to 2022. This decrease is completed by the decrease in share-based 
payments of €0.1 million. As of December 31, 2022, we had 59 employees in general and administrative 
functions, as compared to 65 as of December 31, 2021.

Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal and hiring 
services.  These  expenses  decreased  by  €0.9  million,  or  16.9%,  to  €4.2  million  for  the  year  ended 
December 31, 2022, as compared to an amount of €5.1 million for the year ended December 31, 2021. 

155

 
 
 
This  decrease  results  mainly  from  (i)  an  increase  of  €0.9  million  in  fees  for  strategic  consulting  and 
implementation  of  the  "At-the-Market"  capital  increase  program,  offset  by  (ii)  a  decrease  of  legal 
assistance  costs,  support  costs  by  external  service  providers  in  the  context  of  compliance  with  the 
Sarbanes-Oxley (SOX) Act and costs relating to our wholly owned U.S. subsidiary, Innate Pharma Inc. 

Other  general  and  administrative  expenses  relate  to  intellectual  property,  the  costs  of  maintaining 
laboratory equipment and our premises, depreciation and amortization and other general, administrative 
expenses.  These  expenses  increased  by  €1.6  million  or  16.5%  to  €8.0  million  for  the  year  ended 
December 31, 2022, as compared to an amount of €9.5 million for the year ended December 31, 2021. 
This decrease related notably to the reversals of provisions for charges in connection with restructuring 
costs  linked  to  the  abandonment  of  the  Company's  commercial  activities,  as  well  as  reversals  of  tax 
provisions,  both  with  the  2021  financial  year.  These  elements  are  completed  by  a  net  position  of  more 
favorable commercial exchange gains over the 2022 financial year.

Impairment of intangible assets

For the year ended December 31, 2022, impairment of intangible assets results from full impairment of 
anti-C5aR rights acquired from Novo/Nordisk A/S (avdoralimab intangible asset) for an amount of €41.0 
million. During 2022 fourth quarter, the Company was informed by the sponsor of the Phase 2 clinical 
trial  evaluating  avdoralimab  in  inflammation  in  BP  indication  of  its  decision  to  stop  said  trial. 
Consequently,  the  Company  decided  in  December  2022  to  stop  the  development  of  avdoralimab  in  BP 
indication  in  inflammation,  only  indication  supporting  the  recoverable  amount  of  the  asset  as  of 
December 31, 2021 (as well that as of June 30, 2022). 

Financial income (loss), net 

Net  financial  result  decreased  by  €2.9  million,  to  a  €0.5  million  loss  for  the  year  ended  December  31, 
2022,  as  compared  to  a  €2.3  million  gain  for  the  year  ended  December  31,  2021.  This  change  results 
mainly from the change in the fair value of certain financial instruments (net loss of €1.6 million in 2022 
as compared to a €1.1 million gain in 2021) and a net foreign exchange gain of €0.8 million in 2022 as 
compared to a net foreign exchange gain of €1.2 million in 2021.

The  table  below  presents  the  components  of  our  net  financial  result  for  the  years  ended  December  31, 
2021 and 2022:

For the years ended December 31, 2021 and 2022, the foreign exchange gains and losses mainly result 
from the variance of the exchange rate between the Euro and the U.S. dollar on U.S. dollar-denominated 
cash  and  cash  equivalents,  short-term  investments  and  financial  assets.  Unrealized  gains  and  losses  on 
financial assets relate to unquoted instruments.

Net result from discontinued operations 

Subsequently to the Termination and Transition Agreement, operations related to Lumoxiti are presented 
as a discontinued operation as of October 1, 2021. 

As  a  consequence,  the  Lumoxiti  activity  (including  sales)  is  presented  in  the  consolidated  income 
statement and the notes to the consolidated financial statements as a discontinued operation for the 2021 
financial year in accordance with IFRS5 "non-current assets held for sale and discontinued operations." 

As  a  consequence,  net  result  from  discontinued  operations  relating  to  Lumoxiti  represents  a  net  loss  of 
€7.3  million  as  compared  to  a  net  loss  €0.1  million  for  the  years  ended  December  31,  2021  and  2022,

(1)  Research and development expenses. Research and development expenses relating to Lumoxiti discontinued operations amounted to €0.6 

million and nil for the years ended December 31, December 31, 2021 and 2022, respectively. 

(2)  Selling, general and administrative expenses. Selling, general and administrative expenses relating to Lumoxiti discontinued operations 
amounted  to  €8.5  million  and  €0.3  million  for  the  years  ended  December  31,  2021  and  2022,  respectively.  For  the  year  ended  the 
December  31,  2021,  these  expenses  mainly  consisted  of  the  amount  of  $6.2  million  (€5.5  million)  to  be  paid  on  April  30,  2022  to 
AstraZeneca  under  the  Termination  and  Transition  Agreement.That  amount  was  paid  in  2022  by  the  Company  in  April  2022  for  €5.9 
million ($6.2 million).

Critical Accounting Policies and Significant Judgments and Estimates

The  Company's  consolidated  financial  statements  are  prepared  in  accordance  with  IFRS.  Some  of  the 
accounting  methods  and  policies  used  in  preparing  the  financial  statements  under  IFRS  are  based  on 
complex  and  subjective  assessments  by  our  management  or  on  estimates  based  on  past  experience  and 
assumptions  deemed  realistic  and  reasonable  based  on  the  facts  and  circumstances.  The  actual  value  of 
the Company's assets, liabilities and shareholders’ equity, as well as its income and expenses, could differ 
from the value derived from these estimates if conditions changed and these changes had an impact on the 
assumptions adopted. See Note 2 to the Company's consolidated financial statements appearing elsewhere 
in this Annual Report. 

The  Company  believes  that  the  most  significant  management  judgments  and  assumptions  in  the 
preparation of its consolidated financial statements are described below. 

Accounting for collaboration and licensing arrangements 

To  date,  the  Company's  revenue  has  been  generated  primarily  from  payments  received  in  relation  to 
research, collaboration and licensing agreements signed with pharmaceutical companies. These contracts 
generally provide for components such as upfront payments, milestone payments upon reaching certain 
predetermined  development  objectives,  research  and  development  funding,  as  well  as  payment  of 
royalties on future sales of products. 

Non-refundable  upfront  payments  are  deferred  and  recognized  as  revenue  over  the  period  Innate  is 
engaged  to  deliver  services  to  the  third  party.  Revenue  is  recognized  based  on  completion  of  the 
underlying work. 

Milestone  payments  represent  amounts  received  from  Innate's  collaborators,  the  receipt  of  which  is 
dependent  upon  the  achievement  of  certain  scientific,  regulatory,  or  commercial  milestones.  The 
Company  recognizes  milestone  payments  when  the  triggering  event  has  occurred,  there  are  no  further 
contingencies or services to be provided with respect to that event, and the counterparty has no right to a 
refund of the payment. The triggering event may be scientific results achieved by the Company or another 
party  to  the  arrangement,  regulatory  approvals,  or  the  marketing  of  products  developed  under  the 
arrangement.  As  of  December  31,  2023,  given  the  significant  progress  of  the  work  to  be  performed 
(98.1%)  and  the  level  of  budget  consumption,  the  impact  of  accounting  estimates  is  no  longer  a 
determining factor in the calculation of revenue related to the monalizumab agreement.

Estimate of the recoverable amount of the acquired and under progress licenses 

Impairment tests are performed on a yearly basis for the intangible assets which are not amortized (such 
as  intangible  assets  in  progress).  The  Company  is  testing  amortizable  intangible  assets  for  impairment 
when there is an indicator of impairment. Impairment tests involve comparing the recoverable amount of 
the licenses to their net book value. The recoverable amount of an asset is the higher of its fair value less 
costs to sell and its value in use. If the carrying amount of any asset is above its recoverable amount, the 
Company recognizes an impairment loss to reduce the carrying amount to the recoverable amount. The 
main assumptions used for the impairment test include (a) the amount of cash flows that are set on the 
basis  of  the  development  and  commercialization  plans  and  budgets  approved  by  management,  (b) 
assumptions related to the achievement of the clinical trials and the launch of the commercialization, (c) 
the discount rate, (d) assumptions on risk related to the development and (e) for the commercialization, 
selling  price  and  volume  of  sales,  and  are  provided  in  Note  6  to  the  Company's  consolidated  financial 
statements which are included elsewhere in this Annual Report. Any change in these assumptions could 

159

lead  to the recognition of an impairment charge that could have a significant impact on the Company's 
consolidated  financial  statements.  In  case  of  failure  of  the  clinical  trials  in  progress,  the  Company  may 
have to fully depreciate the intangible asset. As of December 31, 2022, given the Company's decision in 
December  2022  to  discontinue  the  development  of  avdoralimab  in  the  indication  of  BP  supporting  the 
recoverable  amount  of  the  asset  as  of  December  31,  2021  and  June  30,  2022,  the  rights  related  to  the 
intangible asset have been fully impaired for the net carrying amount of the intangible asset, of €41,000 
thousand,  without  using  the  historical  assumptions  described  above  (see  Note  6  to  the  Company's 
consolidated  financial  statements  which  are  included  elsewhere  in  this  Annual  Report).  As  a  result,  the 
Company  considers  that  there  are  no  longer  any  critical  estimates  in  line  with  intangible  assets  since 
2022.  Without  any  new  event  to  be  considered  since  then,  there  are  therefore  no  longer  any  critical 
assumptions that could call into question the recoverable amount of the asset. 

B. Liquidity and Capital Resources

The liquidity and capital resources discussion that follows contains certain estimates as of the date of this 
Annual  Report  of  the  Company's  estimated  future  sources  and  uses  of  liquidity  (including  estimated 
future  capital  resources  and  capital  expenditures)  and  future  financial  and  operating  results.  These 
estimates  reflect  numerous  assumptions  made  by  Innate  with  respect  to  industry  performance,  general 
business,  economic,  regulatory,  market  and  financial  conditions  and  other  future  events,  and  matters 
specific to its businesses, all of which are difficult or impossible to predict and many of which are beyond 
its control. 

Sources and uses of liquidity 

As  of  December  31,  2023,  the  Company  has  primarily  financed  its  operations  through  its  receipt  of 
$635.4  million  (€560.1  million)  in  payments  from  its  collaborators,  including  AstraZeneca  and  Sanofi, 
since 2011, excluding payments received for purchases of Innate's equity securities by its collaborators. 

Innate  has  also  financed  its  operations  since  its  inception  through  several  rounds  of  public  and  private 
financings.  Since  its  inception,  Innate  has  raised  a  total  of  €311.4  million  through  the  sale  of  equity 
securities,  including  €33.7  million  in  the  initial  public  offering  of  Innate's  ordinary  shares  on  Euronext 
Paris in 2006 and €66.0 million in the initial public offering of the Company's initial public offering of its 
ordinary shares on Nasdaq in 2019. 

In addition, Innate has received an aggregate of €100.1 million in research tax credits through December 
31,  2023.  As  a  French  biopharmaceutical  company,  Innate  Pharma  has  benefited  from  certain  tax 
advantages, including, for example, the research tax credit. The research tax credit can be offset against 
French  corporate  income  tax  due  and  the  portion  in  excess,  if  any,  may  be  refunded.  The  research  tax 
credit is calculated based on Innate's claimed amount of eligible research and development expenditures 
in France. The research tax credit increased by €1.8 million, or 23% , to €9.7 million for the year ended 
December 31, 2023, as compared to a research tax credit of €7.9 million for the year ended December 31, 
2022. 

 Innate lost its status as a small or medium size business at the end of the year ended December 31, 2019 
and, therefore, was no longer entitled to the immediate reimbursement of the research tax credit for the 
fiscal year ended 2019 and 2020 but instead will be reimbursed within the expiry of a three-year period. 
The 2019 tax credit was refunded on February 2023. For the 2021 and 2022 financial year, the Company 
again  met  the  criteria  of  an  SME  according  to  the  criteria  of  the  European  Union.  As  a  result,  the 
Company  was  eligible  for  the  early  repayment  by  the  French  treasury  of  the  2021  research  tax  credit 
during  the  fiscal  year  2022.  The  Company  will  also  be  eligible  for  the  early  repayment  by  the  French 
treasury of the 2022 research tax credit during the fiscal year 2023. As of December, 31 2023 financial 

160

year, the Company lost again the SME status. As a consequence, the 2023 research tax credit will be paid 
after a three-year period. If necessary, the Company could mobilize the receivable. 

Innate  is  potentially  eligible  to  earn  milestone  payments  and  royalties  under  its  agreements  with 
AstraZeneca  in  the  event  that  the  Company  satisfies  certain  pre-specified  milestones.  Innate  may  enter 
into new collaboration agreements that also provide milestone payments. These milestone payments are 
dependent on the accomplishment of various development, regulatory and commercialization objectives, 
and the achievement of many of these milestones is outside of Innate's control. However, Innate's ability 
to  earn  these  payments  and  their  timing  will,  in  part,  be  dependent  upon  the  outcome  of  its  research 
activities, which is uncertain at this time. 

On  July  3,  2017,  Innate  Pharma  borrowed  from  the  bank  Société  Générale  in  order  to  finance  the 
construction  of  its  future  headquarters.  This  loan,  amounting  to  a  maximum  of  €15.2  million,  can  be 
drawn down during the period of the construction in order to pay supplier payments as they become due, 
but in any event no later than August 30, 2019. Given the development of its portfolio, and in particular 
the  refocusing  of  its  activities  on  research  and  development,  the  Company  has  for  the  time  being 
suspended the project to build its new head office on the land acquired in Luminy. In the meantime, the 
loan  will  be  used  to  finance  several  structuring  projects  (improvement  of  the  information  system, 
development of a commercial platform, development of additional premises rented, etc.). Repayment of 
any amounts drawn down are payable over a 12-year term beginning on August 30, 2019 and ending on 
August 30, 2031. As security for the loan, Innate pledged collateral in the form of financial instruments 
held  at  Société  Générale  amounting  to  €15.2  million.  The  security  interest  on  the  pledged  financial 
instruments  will  be  released  in  accordance  with  the  following  schedule:  €4.2  million  in  July  2024, 
€5.0  million  in  August  2027  and  €6.0  million  in  August  2031.  The  Company  had  drawn  down  €15.2 
million under the loan as of December 31, 2019. The loan bears a fixed interest rate of 2.01%. Under the 
loan,  Innate  is  subject  to  a  covenant  that  its  total  cash,  cash  equivalents  and  current  and  non-current 
financial  assets  as  of  each  fiscal  year  end  will  be  at  least  equal  to  the  amount  of  outstanding  principal 
under  the  loan.  The  repayment  period  started  on  August  30,  2019.  As  of  December  31,  2023,  the 
remaining capital of this loan amounted to €10.2 million as compared to €11.3 million as of December 31, 
2022. 

On January 5, 2022, the Company announced that it had obtained non-dilutive financing of €28.7 million 
in  the  form  of  two  State-Guaranteed  Loans  (Prêts  Garantis  “PGE”)  from  Société  Générale 
(€20.0 million) and BNP Paribas (€8.7 million). The funds related to these two PGEs were collected by 
the Company on December 27 and 30, 2021, respectively. These two loans have an initial maturity of one 
year, with an option to extend up to five years from August 2022. They are 90% guaranteed by the French 
State as part of a system put in place to support companies in the face of the COVID-19 health crisis. In 
August 2022, the Company requested the extension of these two loans repayment for an additional period 
of five years starting in 2022 and including a one-year grace period (2023). Consequently, the Company 
has obtained agreements from Société Générale and BNP Paribas. The effective interest rates applied to 
these contracts during the additional period are 1.56% and 0.95% for Société Générale and BNP Paribas 
loans, respectively, excluding insurance and guarantee fees, with an amortization exemption for the entire 
year 2023. During this grace period, the Company will only be liable for the payment of interest and the 
guarantee fees, with amortization of the two loans starting in 2024 over a period of four years. The state 
guarantee fees amount to €877 thousand and €379 thousand for Société Générale and BNP Paribas loans 
respectively. As of December 31, 2023, the remaining capital of these loans amounted to €28.7 million.

Lastly, during the years ended December 31, 2016 and 2017, Innate also used lease-financing and bank 
loans to finance the acquisition of laboratory equipment and to set up new laboratories. The debt related 
to these loans amounts to €0.2 million at December 31, 2023.

Cash, cash equivalents and short-term investments decreased by €9.0 million, or 9%, to €92.5 million as 
of  December  31,  2023,  as  compared  to  cash,  cash  equivalents  and  short-term  investments  of  €101.5 
million  as  of  December  31,  2022.  Cash  and  cash  equivalents  are  mainly  composed  of  current  bank 
accounts, interest-bearing accounts, fixed-term accounts and money market funds as per AMF definition. 
Short-term  investments  primarily  consist  of  shares  of  mutual  funds  and  all  investments  with  a  maturity 
less  than  one  year.  Their  purpose  is  to  finance  Innate's  activities,  including  Innate's  research  and 
development costs. 

As  a  reminder,  Innate  has  received  a  total  of  €306.4  million  in  cash  from  capital  increases,  before 
deducting  the  costs  associated  with  capital  increases,  and  after  excluding  proceeds  from  share

Cash flows from / (used in) operating activities 

The Company's net cash flow used in operating activities decreased by €13.4 million to €32.6 million for 
the  year  ended  December  31,  2023  as  compared  to  net  cash  flows  used  in  operating  activities  of €19.2 
million  for  the  year  ended  December  31,  2022.  This  variation  is  mainly  due  to  (i)  the  receipt  of  €25.0 
million  from  Sanofi  in  March  2023  following  the  entry  into  force  of  the  research  collaboration  and 
licensing agreement signed in December 2022 under which the Company granted Genzyme Corporation, 
a wholly-owned subsidiary of Sanofi ("Sanofi") an exclusive licence to Innate Pharma's B7H3 ANKET® 

163

 
 
 
program and options on two additional targets, (ii) the receipt in May 2023 of a payment of €4.6 million 
($5.0 million) received from Takeda following the conclusion of an exclusive licensing agreement under 
which Innate granted Takeda exclusive worldwide rights for the research and development of ADCs, (iii) 
the receipt in July 2023 of €2.0 million following the treatment of the first patient in the Phase 1/2 clinical 
trial  sponsored  by  Sanofi  evaluating  IPH6401/SAR'514  in  patients  with  relapsed  or  refractory  multiple 
myeloma. Lastly, during 2023, the Company benefited from the early repayment of the research tax credit 
claim relating to the 2022 financial year, amounting to €9.2 million, paid to the Company by the French 
Treasury in July 2023. As a reminder, cash flows used in operating activities for the year ended December 
31,  2022,  included  successive  (i)  the  collection  of  €47.7  million  ($50.0  million)  and  €4.9  million  ($5.0 
million)  in  June  2022  and  August  2022,respectively,  under  the  monalizumab  agreement  and  the 
amendment  to  the  IPH5201  collaboration  and  option  agreement,  (ii)  the  collection  of  €3.0  million 
received  from  Sanofi  under  the  2016  agreement  and  following  Sanofi's  decision  to  advance  IPH6401/
SAR'514  into  regulatory  preclinical  studies  for  an  investigational  new  drug,  and  (iii)  in  2022,  the 
Company collected the early repayment of the research tax credit receivable relating to the 2021 financial 
year  for  an  amount  of  €10.3  million,  paid  to  the  Company  by  the  French  Treasury  in  November  2022. 
These  collections  were  partially  offset  by  the  €5.9  million  payment  to  AstraZeneca  on  April  20,  2022 
pursuant  to  the  Termination  and  Transition  Agreement  and  cash  outflows  related  to  the  Company's 
operating activities. Not considering these specific effects, net cash flows used by operating activities for 
the year ended December 31, 2023 decreased by €5.5 million. This decrease is mainly explained by the 
decrease in the Company's research and development activities, notably related to preclinical trials, and 
also  by  higher  cash  outflows  related  to  the  re-invoicing  of  costs  to  AstraZeneca  for  the  Phase  3  trials 
evaluating  monalizumab,  INTERLINK-1  and  PACIFIC-9,  in  accordance  with  the  Company's  co-
financing commitments and the reduction in staff costs related to the reduction of staff in the Company. 

Net cash flow consumed by operating activities in connection with the Lumoxiti discontinued operation 
are nil for the year ended December 31, 2023 as compared to € 5.1 million for the year 2022. In 2022, the 
cash  consumption  related  to  the  payment  to  AstraZeneca  of  €5.9  million  in  April  2022  under  the 
Termination and Transition Agreement.

Cash flows from / (used in) investing activities 

The Company's net cash flows from investing activities for the year ended December 31, 2023 amounted 
to  €20.6  million  and  are  mainly  composed  of  a  disposal  of  a  non-current  financial  instrument  which 
generated  a  net  cash  collection  of  €22.8  million  partially  offset  by  acquisitions  of  property,  plant  and 
equipment  and  intangible  assets  for  a  net  amount  €2.2  million.  As  a  reminder,  net  cash  flow  used  in 
investing  activities  for  the  year  ended  December  31,  2022  amounted  to  €1.9  million  and  were  mainly 
comprised of acquisitions of tangibles assets and disposal of a current financial instrument liquidation for 
€3.0 million. 

Net cash flows consumed by investing activities in connection with the Lumoxiti discontinued operation 
were nil for the year ended December 31, 2023 and 2022, respectively.

Cash flows from / (used in) financing activities 

The  Company's  net  cash  flows  used  in  financing  activities  for  the  year  ended  December  31,  2023 
increased by €0.1 million to €2.0 million for the year ended December 31, 2023 as compared to net cash 
flows from financing activities of €1.8 million for the year ended December 31, 2022. 

Loan repayments amounted to €2.4 million for the year ended December 31, 2023 as compared to €2.0 
million for the year ended December 31, 2022. 

In addition, net cash flows from financing activities related to Lumoxiti discontinued operations are nil 
for the year ended December 31, 2022 and 2021, respectively.

Cash flows from / (used in) operating activities 

The Company's net cash flow used in operating activities decreased by €39.3 million to €19.2 million for 
the  year  ended  December  31,  2022  as  compared  to  net  cash  flows  used  in  operating  activities  of  €58.5 
million  for  the  year  ended  December  31,  2021.  This  increase  mainly  results  from  (i)  the  collection  of 
€47.7 million ($50.0 million) and €4.9 million ($5.0 million) in June 2022 and August 2022,respectively, 
under  the  monalizumab  agreement  and  the  amendment  to  the  IPH5201  collaboration  and  option 
agreement,  (ii)  the  collection  of  €3.0  million  received  from  Sanofi  under  the  2016  agreement  and 
following  Sanofi's  decision  to  advance  IPH6401/SAR'514  into  regulatory  preclinical  studies  for  an 
investigational  new  drug.  Finally,  (iii)  the  Company  collected  during  2022  the  early  repayment  of  the 
research tax credit receivable relating to the 2021 financial year for an amount of €10.3 million, paid to 
the Company by the French Treasury in November 2022. These collections are partially offset by the €5.9 
million payment to AstraZeneca on April 20, 2022 pursuant to the Termination and Transition Agreement 
and  cash  outflows  related  to  the  Company's  operating  activities.  As  a  reminder,  cash  flows  used  in 
operating activities for year ended December 31, 2021, included successive receipts for a total amount of 
€10.0 million from Sanofi (in January, February and December 2021) in connection with the IPH6101/
SAR443579  agreement  signed  in  2016,  following  Sanofi's  decision  at  the  end  of  2020  to  advance 
IPH6101/SAR443579  towards  regulatory  preclinical  studies  for  a  new  investigational  drug,  and  the 
launch of the first related Phase 1 trial in December 2021. Restated of these receipts and payments, net 
cash  flows  used  by  operating  activities  for  the  year  ended  December,  2022  increased  by  €10.4  million. 
This increase is mainly explained by the increase in the Company's research and development activities, 
notably related to pre-clinical trials, and also by higher cash outflows related to the re-invoicing of costs 
to  AstraZeneca  for  the  Phase  3  trials  evaluating  monalizumab,  INTERLINK-1  and  PACIFIC-9,  in 
accordance with the Company's co-financing commitments. 

Net cash flow consumed by operating activities in connection with the Lumoxiti discontinued operation 
amounted to €5.1 million for the year ended December 31, 2022 as compared to € 3.6 million for the year 
2021. This increase is mainly related to the payment to AstraZeneca of €5.9 million in April 2022 under 
the Termination and Transition Agreement.

Cash flows from / (used in) investing activities 

The Company's net cash flows from investing activities for the year ended December 31, 2022 amounted 
to  €1.9  million  and  are  mainly  composed  of  a  disposal  of  a  non-current  financial  instrument  which 
generated  a  net  cash  collection  of  €3.0  million  partially  offset  by  acquisitions  of  property,  plant  and 
equipment and intangible assets for €1.1 million. As a reminder, net cash flow used in investing activities 
for  the  year  ended  December  31,  2021  amounted  to  €0.9  million  and  were  mainly  comprised  of 
acquisitions of tangibles assets.

(€20.0  million)  and  BNP  Paribas  (€8.7  million).  The  Company  received  the  funds  related  to  these  two 
loans on December 27 and 30, 2021, respectively.

Funding requirements 

Innate  Pharma  believes  that  its  existing  cash,  cash  equivalents,  short-term  investments  and  non-current 
financial assets, will enable it to fund its operations for at least the next 12 months. Innate has based this 
estimate  on  assumptions  that  may  prove  to  be  wrong,  and  the  Company  could  use  its  capital  resources 
sooner than it currently expects. 

Until Innate can generate a sufficient amount of revenue from the sale of approved products, if ever, it 
expects to finance its operating activities through its existing liquidity and expected milestone payments 
from collaborators. 

Innate's  present  and  future  funding  requirements  will  depend  on  many  factors,  including,  among  other 
things: 

•

•

•

•

•

the  size,  progress,  timing  and  completion  of  its  clinical  trials  and  preclinical  studies  for  any 
current or future product candidates, including its lead product candidates, monalizumab and 
lacutamab; 

the number of potential new product candidates Innate identifies and decides to develop; 

costs  associated  with  its  payment  obligations  to  third  parties  in  connection  with  its 
development and potential commercialization of certain of its product candidates; 

costs associated with expanding its organization; 

the  costs  involved  in  filing  patent  applications  and  maintaining  and  enforcing  patents  or 
defending against claims of infringement raised by third parties; 

166

•

•

the time and costs involved in obtaining regulatory approval for its product candidates and any 
delays the Company may encounter as a result of evolving regulatory requirements or adverse 
results with respect to any of these product candidates; 

the  amount  of  revenues,  if  any,  Innate  Pharma  may  derive  either  directly,  or  in  the  form  of 
milestone  or  royalty  payments  from  any  future  potential  partnership  agreements,  from 
monalizumab,  IPH5201,  IPH6101/SAR443579,  IPH6401/SAR'514,  B7H3  or  other  target  or 
relating to its other product candidates. 

For more information as to the risks associated with Innate's future funding needs, see “Risk Factors—
The  Company  may  need  to  raise  additional  funding  to  complete  the  development  and  any 
commercialization  of  its  product  candidates,  which  may  not  be  available  on  acceptable  terms,  or  at  all, 
and  failure  to  obtain  this  necessary  capital  when  needed  may  force  the  Company  to  delay,  limit  or 
terminate its product development efforts or other operations.”

Capital expenditures 

Innate  Pharma's  operations  mainly  require  investment  in  intangible  assets.  Innate  acquired  the  rights  of 
avdoralimab  from  Novo  Nordisk  A/S  in  2017.  The  Company  paid  an  upfront  fee  of  €40.0  million,  of 
which  €37.2  million  was  contributed  in  new  ordinary  shares  and  €2.8  million  in  cash.  As  part  of  this 
agreement,  an  additional  amount  of  €  1.0  million  was  paid  in  October  2020  to  Novo  Nordisk  A  /  S 
following the launch of the first avdoralimab Phase 2 trial.

In January 2019, Innate Pharma paid to AstraZeneca an initial payment for the license related to Lumoxiti 
($50.0 million, or €43.8 million, using the foreign exchange rate of 1.1422 at the date of payment), and in 
February  2019,  Innate  paid  to  Novo  Nordisk  A/S  additional  consideration  relating  to  monalizumab 
($15.0 million, or €13.1 million, using the exchange rate of 1.1394 at the date of payment). In June 2019, 
Innate paid €7.0 million to Orega Biotech in relation to the anti-CD39 program as consideration following 
the collaboration and option agreement signed on October 22, 2018 with AstraZeneca regarding IPH5201. 

Innate's operations generally require little investment in tangible assets because the Company outsources 
most  of  the  manufacturing  and  research  activities  to  third  parties.  Innate  Pharma  leases  some  of  its 
computer equipment under operating lease agreements. Innate accounts for its payments for these items as 
operating expenses in the consolidated statement of income. 

The  Company's  capital  expenditures  in  the  years  ended  December  31,  2021,  2022  and  2023  primarily 
related  to  laboratory  equipment.  Clinical  research  and  development  costs  are  not  capitalized  until 
marketing authorizations are obtained. 

Innate's corporate office in Luminy, Marseille, France is leased under a finance lease agreement signed in 
2008 with Sogebail, a subsidiary of Société Générale, for an aggregate amount of €6.6 million. The lease-
financing agreement has a 12-year term. Innate has a purchase option for all of the buildings and land for 
the lump sum of €1 at the end of the term of the contract on June 9, 2020, which it has exercised. The 
Company now owns its corporate office in Luminy, Marseille. 

Since July 2017, Innate also rents office space in Marseille, France under a commercial lease. 

On  January  10,  2020,  the  Company  signed  an  amendment  to  the  lease  for  the  “Le  Virage”  building  in 
order to expand its premises. This amendment also extended the duration of the contractual commitment 
until 2025. 

On March 13, 2023, the Company signed an amendment to the lease for "Le Virage Building" in order to 
reduce the rental area of its premises located in the "Le Virage" building. This amendment has the effect 
of  reducing  the  amount  of  the  commitment  relating  to  rent  by  €685  thousand.  The  Company  remains 
committed under this contract until June 30, 2025.

•

•

Fixed Compensation. The members of the Executive Board receive a fixed compensation pursuant 
to  their  employment  agreements  or,  in  the  case  of  the  Chairman,  his  social  mandate  (mandat 
social). 

Annual Variable Compensation. The members of the Executive Board are eligible to receive annual 
variable compensation upon the recommendation of the Compensation and Nomination Committee 
based on the achievement of pre-specified objectives. For the year ended on December 31, 2023, 
such  objectives  were  based  on  the  achievement  of  the  Company's  main  strategic  pillars  and 
operational targets defined according to Innate Pharma's activities in order to (i) take into account 
the outperformance inherent to a fast-growing biotech company and (ii) motivate the executives to 
exceed their objectives. 

177

The  strategic pillars are the following: (i) maximizing the value of Lacutamab, (ii) advancing the 
R&D  portfolio,  (iii)  sustaining  the  Company's  business,  complemented  by  two  other  pillars:  (iv) 
finance and (v) CSR (Corporate and Social Responsibility)

Each pillar was subdivided into:

(i) a baseline target; and

(ii) an outperformance target.

of  achievement  of  the  targets.  In  case  of  outperformance  for  the  year  2023,  it  may  be  decided  to 
increase  the  amount  of  the  bonus  beyond  100%  up  to  a  limit  of  150%  based  on  other  predefined 
criteria. 

The outperformance targets may only be reached if 100% of the baseline targets are reached.

authorization  of  the  Supervisory  Board  and  upon  recommendation  of  the  Compensation  and

Executive Compensation Clawback  Policy

Pursuant  to  the  rules  adopted  by  the  SEC  pursuant  to  Section  10D-1  of  the  Exchange  Act,  requiring 
national  securities  exchanges  and  national  securities  associations,  such  as  the  NYSE,  to  amend  their 
relevant listing standards no later than November 28, 2023 to require companies with listed securities to 
put in place a policy whereby listed companies will recover erroneously-awarded variable compensation 
from the Chief Executive Officer and certain other “executive officers” as defined in Rule 10D-1(d) under 
the Exchange Act. On June 9, 2023, the SEC approved the Nasdaq’s proposed rule amending its listing 
standards for recovery of erroneously awarded compensation by listed issuers, which has taken effect on 
October 2, 2023. 

On October 13, 2023, the Supervisory Board approved the adoption of a clawback policy, applicable from  
October  2,  2023,  requiring  the  recovery  in  full  or  in  part  of  the  components  of  the  Chief  Executive 
Officer's compensation that are wholly or partially contingent on the attainment of financial performance 
criteria  based  on  financial  information  that  has  been  determined  to  be  erroneous  and  has  required 
restatement of the financial statements for accounting purposes.

achievement of the targets. In case of outperformance for the year 2024, the amount of the bonus may be 
increased beyond 100% up to a limit of 150% based on other predefined criteria.

The outperformance targets may only be reached if 100% of the baseline targets are reached.

At the general meeting of shareholders of the Company to be held on May 23, 2024, the allocation of free 
performance shares subject to capitalization evolution and internal conditions will be put to the vote of its 
shareholders.

Limitations on Liability and Indemnification Matters

Under  French  law,  provisions  of  bylaws  that  limit  the  liability  of  the  members  of  Executive  and 
Supervisory  Boards  are  prohibited.  However,  French  law  allows  sociétés  anonymes  to  contract  for  and 
maintain  liability  insurance  against  civil  liabilities  incurred  by  members  of  Executive  and  Supervisory 
Boards involved in a third-party action, provided that they acted in good faith and within their capacities 
as members of such Boards of the Company. Criminal liability cannot be indemnified under French law, 
whether directly by the Company or through liability insurance. 

The Company has a liability insurance for its Executive and Supervisory Board members, and insurance 
coverage  for  liability  under  the  Securities  Act.  The  Company  also  entered  into  agreements  with  its 
Executive  and  Supervisory  Board  members  to  provide  contractual  indemnification.  With  certain 
exceptions and subject to limitations on indemnification under French law, these agreements provide for 
indemnification  for  damages  and  expenses  including,  among  other  things,  attorneys’  fees,  judgments, 
fines and settlement amounts incurred by any Executive or Supervisory Board member in any action or 
proceeding arising out of his or her actions in that capacity. The Company believes that this insurance and 
these agreements are necessary to attract qualified Executive and Supervisory Board members. 

These  agreements  may  discourage  shareholders  from  bringing  a  lawsuit  against  the  Executive  and 
Supervisory Board members for breach of their fiduciary duty. These provisions also may have the effect 
of reducing the likelihood of derivative litigation against the Executive and Supervisory Board members, 
even  though  such  an  action,  if  successful,  might  otherwise  benefit  the  Company  and  its  shareholders. 
Furthermore, a shareholder’s investment may be adversely affected to the extent the Company pays the 
costs of settlement and damages awards against its Executive and Supervisory Board members pursuant 
to these insurance agreements.

Equity Incentives

The Company believes that the ability to grant equity incentives is a valuable and necessary compensation 
tool  that  allows  the  Company  to  attract  and  retain  the  best  personnel  for  positions  of  substantial 
responsibility, provides additional incentives to employees and promotes the success of its business. Due 
to  French  corporate  law  and  tax  considerations,  the  Company  has  historically  granted  several  different 
equity  incentive  instruments  to  its  Executive  Board  and  Supervisory  Board  members,  employees  and 
consultants,  including  (i)    warrants  (BSAs),  which  have  historically  only  been  granted  to  independent 
members  of  the  Supervisory  Board  and  consultants,  (ii)  redeemable  warrants  (BSAARs)  and  (iii)  free 
shares. 

The  Executive  Board’s  authority  to  grant  these  warrants  and  free  shares  and  the  aggregate  amount 
authorized  to  be  granted  must  be  approved  by  two-thirds  of  the  shareholders  present  at  the  relevant 
extraordinary  shareholders’  meeting.  Once  approved  by  the  shareholders,  the  Executive  Board  can 
continue to grant such awards for a specified period upon prior authorization of the Supervisory Board. 

The  Company  has  various  compensation  plans  for  its  Executive  Board  members,  Supervisory  Board 
members, employees and consultants that have been approved by the shareholders. The last allocation of 
BSAARs which occurred in 2015 no longer continues to vest following termination of the employment, 
office or service of the holder within the first two years and all vested warrants must be exercised within 
post-termination exercise periods set forth in the issuance agreement. In the event of certain changes in its 
share  capital  structure,  such  as  a  consolidation  or  share  split  or  dividend,  French  law  and  applicable 
issuance agreement provides for appropriate adjustments of the numbers of ordinary shares issuable and/
or the exercise price of the outstanding warrants. 

As  of  December  31,  2023,  the  Company  had  the  following  equity  awards,  warrants  and  free  shares 
outstanding: 

•

•

presence conditions are met.

Equity Warrants and Redeemable Share Subscription Warrants 

Share Warrants (BSA)

Share warrants (BSA) are issued at a de minimis price and entitle the holder of one BSA to exercise the 
warrant for one underlying share, at an exercise price per share determined by the Executive Board of the 
Company  at  the  time  of  issue  by  reference  to  the  then  prevailing  share  price.  The  Company  has  issued 
BSA to Supervisory Board members and certain consultants of the Company. The Company's BSA plans 
include  provisions  that  allow  for  the  adjustment  of  the  one-for-one  exercise  ratio  to  compensate  for 
certain  modifications  of  its  share  capital,  such  as  rights  issues,  stock  splits,  mergers  and  other  events 
affecting all existing shareholders. None of those events have occurred yet. The Company's BSA have an 
exercise period of 10 years – BSA not exercised after that time lapse and are automatically cancelled. The 
Company's BSA cannot be sold.

Redeemable Share Warrants (BSAAR) 

Redeemable share warrants, or BSAAR, are identical to the share warrants of BSA (including the one-for-
one exercise ratio, its potential adjustment for certain modifications of the share capital and the exercise 
period of 10 years), except for the following features: 

•

the BSAAR are initially purchased by the beneficiary at their fair value, as determined by an expert, 
and 

183

•

the  BSAAR  plans  include  a  “forcing”  clause  making  it  possible  to  encourage  holders  to  exercise 
their BSAAR when the market price exceeds the exercise price and reaches a threshold defined in 
the BSAAR issuance agreement. The Company can then, subject to a time period for notifying the 
holders that will permit them to exercise their BSAAR, decide to purchase the unexercised BSAAR 
at a unit price equal to the BSAAR acquisition price initially paid by their holders. 

Innate's  redeemable  share  warrants  cannot  be  sold.  The  BSAAR  have  been  granted  to  certain  of  the 
executive officers and employees.

Free Shares (AGA) 

Free  shares  (AGA)  are  employee  equity  incentive  instruments  pursuant  to  which  the  beneficiaries  are 
granted,  for  free,  the  possibility  to  receive  ordinary  shares  under  certain  conditions.  Upon  grant  by  the 
Executive Board of the Company, the AGA are subject to an acquisition, or vesting, period of at least one 
year.  At  the  end  of  this  period,  the  free  shares  vest  and  the  beneficiary  becomes  a  full  shareholder. 
However, if the vesting period is less than a certain period set by law (currently two years), it must be 
followed by a holding period, so that the sum of the vesting period and the holding period is equal to a 
minimum total period also set by law (currently two years). Vesting can be conditional or not. The vesting 
of all or the Company's AGA is subject to a presence condition at the end of the vesting period. Some of 
the  Company's  AGA  are  also  subject  to  performance  conditions.  Over  the  years,  the  Company  has 
established  several  AGA  plans,  for  its  employees  or  for  management  only,  sometimes  as  a  “welcome 
package” (with no performance conditions). The Company's free share plans include provisions that allow 
for  the  adjustment  of  the  number  of  ordinary  shares  to  which  a  beneficiary  is  entitled  at  the  end  of  the 
vesting  period  to  compensate  for  certain  modifications  of  its  share  capital,  such  as  rights  issues,  stock 
splits, mergers and other events affecting all existing shareholders, during the vesting period. Certain of 

184

the  Company's  plans  also  provide  for  an  accelerated  vesting  in  case  of  a  tender  offer  on  the  Company 
during the vesting period.

(1) Usually after the end of the vesting period, the Executive Board will convene and acknowledge the number of free shares that have vested 
and the number of those that have not because the presence condition and, as applicable, the performance conditions, have not been met. 
For  the  purpose  of  computing  the  amount  of  share-based  compensation  in  its  consolidated  financial  statements,  AGA  that  have  lapsed 
because the presence condition has not been met, are excluded from the computation, even though the Executive Board has not met yet 
and  formally  acknowledged  this  fact.  As  a  result,  certain  of  the  numbers  above  are  different  from  those  in  its  consolidated  financial 
statements.

185

The following authorization will be submitted for approval to the general meeting of the shareholders to 
be held on May 23, 2024: (i)  up to 1,425,000 free shares with performance conditions to the benefit of 
executive  officers,  employed  members  of  the  Leadership  Team,  employed  senior  executives  and/or 
corporate  officers,  (ii)  up  to  1,200,000  free  shares  with  performance  conditions  to  the  benefit  of 
employees, (iii) up to 300,000 free shares to the benefit of new executive officers without performance 
conditions, (iv) up to 300,000 free shares to the benefit of employees and Leadership Team and Executive 
Board (excluding the Chairman) members as part of the employee saving plan, (v) up to 150,000 stock 
options  to  the  benefit  of  new  executive  officers  and  (vi)  up  to  40,000  warrants  to  the  benefit  of 
independent Supervisory Board members to be issued at the fair market value.

Free Preferred Shares (AGAP) 

Free preferred shares (AGAP) are another employee equity incentive instrument similar to the free shares 
or AGA, except that, after a one-year vesting period, the beneficiaries receive a preferred shares (shares 
B) which will become convertible into ordinary shares following a lock-up period of two additional years, 
if the performance conditions (and a presence condition) are met at the end of this lock-up period. Each 
free  preferred  share  is  convertible  into  a  number  of  ordinary  shares  of  the  Company  –  which  number 
depends  upon  the  degree  of  fulfilment  of  the  performance  conditions.  The  free  preferred  shares  remain 
convertible  into  ordinary  shares  for  a  period  of  six  years  and  six  months.  Free  preferred  shares  not 
converted  at  the  end  of  this  conversion  period  can  be  repurchased  by  Innate  and  cancelled.  The 
Company's AGAP cannot be sold. 

The  Company  has  established  several  AGAP  plans  in  2016  and  2017  for  all  of  its  employees  or  for 
management only. 

Since  the  end  of  the  lock-up  period,  holders  of  the  2016  AGAP  that  have  not  yet  converted  them  into 
ordinary  shares,  are  entitled  to  vote  at  the  shareholders’  meetings,  to  dividends  and  to  preferential 
subscription rights, on the basis of the number of ordinary shares to which they are entitled if they convert 
their AGAP. 

On  October  21,  2019,  the  performance  criteria  of  the  2016-1  AGAP  were  assessed  and  the  conversion 
ratio was determined as follows: one 2016-1 AGAP gives right to 130 ordinary shares.

On December 30, 2019, the performance criteria of the 2016-2 AGAP were assessed and the conversion 
ratio was determined as follows: one 2016-2 AGAP gives right to 111 ordinary shares.

The 2017 AGAP  are not convertible since the performance criteria were not met.

C. Board Practices 

Supervisory Board 

The  Supervisory  Board  is  made  up  of  a  minimum  of  three  members  and  a  maximum  of  eighteen.  The 
members of the Supervisory Board are appointed for a renewable term of two years at the general meeting 
of  shareholders,  which  may  revoke  their  appointments  at  any  time.  The  appointees  are  selected  from 
among the shareholders and may be individuals or companies. Each member must own at least one of our 
ordinary  shares  for  the  entire  term  of  the  appointment.  Members  of  the  Supervisory  Board  cannot  be 
members of the Executive Board.

The number of members of the Supervisory Board who have reached the age of seventy years cannot be 
higher than a third of the members of the Supervisory Board. If the age limitation is exceeded, the eldest 
member is deemed to have resigned automatically. 

There  was  no  directors'  service  contracts  with  the  Company  or  any  of  its  subsidiaries  providing  for 
benefits upon termination of employment, for the Company's last completed fiscal year.

Role of the Supervisory Board in Risk Oversight 

The  Supervisory  Board  is  primarily  responsible  for  the  oversight  of  the  risk  management  activities  and 
has delegated to the Audit Committee the responsibility to assist the Supervisory Board in this task. While 
the  Supervisory  Board  oversees  risk  management,  management,  through  the  Executive  Board  is 
responsible for day-to-day risk management processes. The Supervisory Board expects the management 
to consider risk and risk management in each business decision, to proactively develop and monitor risk 
management  strategies  and  processes  for  day-to-day  activities  and  to  effectively  implement  risk 
management  strategies  adopted  by  the  Supervisory  Board.  The  Company  believes  this  division  of 
responsibilities is the most effective approach for addressing the risks the Company faces.

Innate's Audit Committee assists the Supervisory Board in its oversight of the corporate accounting and 
financial  reporting  and  oversees  the  selection  of  the  auditors,  their  remuneration  and  independence  and

determined  that  Ms.  Boissel  is  an  “audit  committee  financial  expert”  as  defined  by  the  Nasdaq  listing 
rules and that each of the members qualifies as financially sophisticated under the Nasdaq Listing Rules. 

The  principal  responsibility  of  the  Audit  Committee  is  to  monitor  the  existence  and  efficacy  of  the

December  31,  2023,  the  members  of  the  committee  are  Pascale  Boissel,  Hervé  Brailly,  Véronique 
Chabernaud and Jean-Yves Blay. The Company's Supervisory Board has determined that Pascale Boissel, 
Hervé Brailly, Véronique Chabernaud and Dr. Jean-Yves Blay are independent within the meaning of the 
applicable Nasdaq listing rules and the independence requirements contemplated by Rule 10A-3 under the 
Exchange Act.

Nomination Committee of September 12, 2022, decided to set up a CSR Committee. The first meeting of 
the committee was held on July, 5th 2023.

As of December 31, 2023, the members of the CSR Committee are Sally Bennett, Véronique Chabernaud, 
Hervé Brailly and Olivier Martinez. 

The main duties of the CSR Committee are to:

Other Committees 

The Strategic Advisory Board 

The  Company  also  has  a  Strategic  Advisory  Board  composed  of  six  external  consultants,  consisting  of 
three individuals from the medical community and three individuals from the scientific community. The 
Strategic  Advisory  Board  is  not  a  committee  of  the  Supervisory  Board  within  the  meaning  of  Article 
R.225-29 of the French Commercial Code; its members are chosen by the Executive Board. This kind of 
advisory committee is common in French companies in the biotechnology sector. 

The Strategic Advisory Board’s role is to assist Innate in the strategic choices in scientific and technical 
fields. Its main missions are to evaluate the relevance of the choices in terms of product development and 
to  propose,  if necessary, changes to strategic or technical approaches; to advise management and guide 
the scientific direction in identifying strategies and selecting product candidates, based, in particular, on 
the scientific results obtained by us, including new targets and new compounds and to promote and advise 
Innate  in  the  alliance  strategies,  such  as  external  growth  supporting  synergies,  including  acquisition  of 
new  competences,  purchase  of  operating  rights,  product  candidates  and  innovative  technologies.  The 
Strategic Advisory Board is comprised of Sebastian Amigorena, Aurélien Marabelle, Ruslan Medzhitov, 
Miriam Merad, Tanguy Seiwert and Mario Sznol. Dr. Merad is the Chairman of the Strategic Advisory 
Board.

Leadership Team

The Company also has a Leadership Team composed of members with significant experience in strategy, 
financial management, medical research, research and development project management, the negotiation 
of  industrial  and  commercial  agreements  in  the  field  of  innovative  companies,  including  biotechnology 

191

companies, compliance and regulations and in business development. The Leadership Team meets at least 
once a month and deals with all subjects regarding the activities and the management of the Company. 

As of December 31, 2023, the members of the Leadership Team were Mondher Mahjoubi, Yannis Morel, 
Sonia Quaratino, Odile Belzunce, Odile Laurent, Frédéric Lombard, Nicola Beltraminelli, Claire de Saint 
Blanquat  and  Henry  Wheeler.  Eric  Vivier,  the  Senior  Vice  President,  Chief  Scientific  Officer,  is  a 
permanent guest to the meetings of the  Leadership Team. 

Corporate Governance Practices 

As  a  French  société  anonyme,  the  Company  is  subject  to  various  corporate  governance  requirements 
under French law. The Company is a “foreign private issuer” under the U.S. federal securities laws and 
the  Nasdaq  listing  rules.  As  a  foreign  private  issuer  listed  on  the  Nasdaq  Global  Market,  we  will  be 
subject  to  the  Nasdaq  corporate  governance  listing  standards.  However,  the  Nasdaq  Global  Market’s 
listing standards provide that foreign private issuers, as defined in the rules promulgated under the U.S. 
Securities  Exchange  Act  of  1934,  as  amended,  (the  “Exchange  Act”),  are  permitted  to  follow  home 
country  corporate  governance  practices  instead  of  certain  Nasdaq  listing  requirements,  with  certain 
exceptions. A foreign private issuer that elects to follow a home country practice instead of Nasdaq listing 
requirements  must  submit  to  Nasdaq  a  written  statement  from  an  independent  counsel  in  such  issuer’s 
home country certifying that the issuer’s practices are not prohibited by the home country’s laws. 

The  Company  applies  the  Middlenext  code,  which  recommends  that  at  least  two  members  of  the 
Supervisory Board be independent (as such term is defined under the code). Certain corporate governance 
practices  in  France  may  differ  significantly  from  Nasdaq’s  corporate  governance  listing  standards. 
Neither the corporate laws of France nor the bylaws requires that (i) a majority of the Members of our 
Supervisory  Board  be  independent  or  (ii)  the  independent  members  of  the  Supervisory  Board  hold 
regularly scheduled meetings at which only independent members of the Supervisory Board are present. 
Other than as set forth below, the Company currently intends to comply with the corporate governance 
listing standards of Nasdaq to the extent possible under French law. However, we may choose to change 
such practices to follow home country practice in the future.

Although we are a foreign private issuer, these exemptions do not modify the independence requirements 
for the Audit Committee. Pursuant to the requirements of the Sarbanes-Oxley Act of 2002 and the Nasdaq 
Listing Rules, our Audit Committee must be composed of at least three independent members. Rule 
10A-3 under the Exchange Act provides that the Audit Committee must have direct responsibility for the 
nomination, compensation and choice of the auditors, as well as control over the performance of their 
duties, management of complaints made, and selection of consultants. Under Rule 10A-3, if the laws of a 
foreign private issuer’s home country require that any such matter be approved by our Supervisory Board 
or the shareholders of the Company, the Audit Committee’s responsibilities or powers with respect to 
such matter may instead be advisory. Under French law, the Audit Committee may only have an advisory 
role and appointment of the statutory auditors, in particular, must be decided by the shareholders at the 
annual meeting. 

In addition, Nasdaq Listing Rules require that a listed company specify that the quorum for any meeting 
of the holders of share capital be at least 33 1/3% of the outstanding shares of the company’s ordinary 
voting shares. The Company intends to follow its French home country practice, rather than complying 
with  this  Nasdaq  Listing  Rule.  Consistent  with  French  Law,  the  Company's  bylaws  provide  that  when 
first convened, general meetings of shareholders may validly convene only if the shareholders present or 
represented hold at least (1) 20% of the voting shares in the case of an ordinary general meeting or of an 
extraordinary  general  meeting  where  shareholders  are  voting  on  a  capital  increase  by  capitalization  of 
reserves, profits or share premium, or (2) 25% of the voting shares in the case of any other extraordinary 
general meeting. If such quorum required by French law is not met, the meeting is adjourned. There is no 

192

quorum  requirement  under  French  law  when  an  ordinary  general  meeting  or  an  extraordinary  general 
meeting is reconvened where shareholders are voting on a capital increase by capitalization of reserves, 
profits  or  share  premium,  but  the  reconvened  meeting  may  consider  only  questions  that  were  on  the 
agenda  of  the  adjourned  meeting.  When  any  other  extraordinary  general  meeting  is  reconvened,  the 
required  quorum  under  French  law  is  20%  of  the  shares  entitled  to  vote.  The  reconvened  meeting  may 
consider  only  questions  that  were  on  the  agenda  of  the  adjourned  meeting.  If  a  quorum  is  not  met  at  a 
reconvened  meeting  requiring  a  quorum,  then  the  meeting  may  be  adjourned  for  a  maximum  of  two 
months. 

Finally, the Company follows French law with respect to shareholder approval requirements in lieu of the 
various shareholder approval requirements of Nasdaq Listing Rule 5635, which requires a Nasdaq listed 
company to obtain shareholder approval prior to certain issuances of securities, including: (a) issuances in 
connection  with  the  acquisition  of  the  stock  or  assets  of  another  company  if  upon  issuance  the  issued 
shares will equal 20% or more of the number of shares or voting power outstanding prior to the issuance, 
or  if  certain  specified  persons  have  a  5%  or  greater  interest  in  the  assets  or  company  to  be  acquired 
(Nasdaq Listing Rule 5635(a)); (b) issuances or potential issuances that will result in a change of control 
of us (Nasdaq Listing Rule 5635(b)); (c) issuances in connection with equity compensation arrangements 
(Nasdaq  Listing  Rule  5635(c));  and  (d)  20%  or  greater  issuances  in  transactions  other  than  public 
offerings,  as  defined  in  the  Nasdaq  rules  (Nasdaq  Listing  Rule  5635(d)).  Under  French  law,  the 
Company’s  shareholders may approve issuances of equity, as a general matter, through the adoption  of 
delegation  of  authority  resolutions  at  the  Company’s  meeting  of  shareholders  pursuant  to  which 
shareholders may delegate their authority to the Executive Board to increase the Company’s share capital 
within specified parameters set by the shareholders, which may include a time limitation to carry out the 
share  capital  increase,  the  cancellation  of  their  preferential  subscription  rights  to  the  benefit  of  named 
persons or a category of persons, specified price limitations and/or specific or aggregate limitations on the 
size  of  the  share  capital  increase.  Due  to  differences  between  French  law  and  corporate  governance 
practices and Nasdaq Listing Rule 5635, the Company follows French home country practice, rather than 
complying with this Nasdaq Listing Rule.

In accordance with French law, committees of our Supervisory Board will only have an advisory role and 
can  only  make  recommendations  to  our  Supervisory  Board.  As  a  result,  decisions  will  be  made  by  our 
Supervisory  Board  taking  into  account  nonbinding  recommendations  of  the  relevant  Supervisory  Board 
committee.

Code of Ethics 

The  Company  has  adopted  a  Code  of  Ethics  applicable  to  all  of  its  employees  and  members  of  its 
Executive Board and Supervisory Board. The Code of Ethics is available on its website. The Company 
expects that any amendments to the Code of Ethics, or any waivers of its requirements, will be disclosed 
on its website.

Executive Compensation Arrangements

Except  the  arrangements  described  in  “Item  7.B—Related  Party  Transactions—Arrangements  with  the 
members of the Executive and Supervisory Boards,” there are no arrangements or understanding between 
Innate and any of the other members of the Executive and Supervisory Boards providing for benefits upon 
termination of their employment, other than as required by applicable law. 

D. Employees

As of December 31, 2023, the Company had 179 full-time employees. Pursuant to French law, employees 
of Innate Pharma  are subject to the French national collective bargaining agreement of Pharmaceutical 
Industries (Convention collective Nationale des Industries Pharmaceutiques). The Company believes that 

193

it maintains good relations with its employees. The following tables show the number of employees as of

Item 7. Major Shareholders and Related Party Transactions

A. Major Shareholders

The  following  table  and  accompanying  footnotes  set  forth,  as  of  December  31,  2023,  information 
regarding beneficial ownership of the ordinary shares by: 

•

•

•

each person, or group of affiliated persons, known by Innate to beneficially own more than 5% of 
the ordinary shares; 

each of the Leadership Team and Supervisory Board members individually; and 

all of the Executive Board and Supervisory Board members as a group. 

Assuming that all of the ordinary shares represented by ADSs are held by residents of the United States, 
as of December 31, 2023, the Company estimates that approximately  4.8 million shares, or 5.97% of the 
ordinary shares were held of record by residents of the United States.  

Beneficial ownership is determined according to the rules of the SEC and generally means that a person 
has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power 
of  that  security,  including  free  shares  that  vest  within  60  days  of  December  31,  2023  and  options  and 
warrants  that  are  currently  exercisable  or  exercisable  within  60  days  of  December  31,  2023.  Ordinary 
shares subject to free shares, options and warrants currently exercisable or exercisable within 60 days of 
December 31, 2023 are deemed to be outstanding for computing the percentage ownership of the person 
holding  these  free  shares,  options  or  warrants  and  the  percentage  ownership  of  any  group  of  which  the 
holder is a member, but are not deemed outstanding for computing the percentage of any other person. 

Except as indicated by the footnotes below, the Company believes, based on the information furnished to 
us, that the persons named in the table below have sole voting and investment power with respect to all 
ordinary shares shown that they beneficially own, subject to community property laws where applicable. 
The information does not necessarily indicate beneficial ownership for any other purpose, including for 
purposes of Sections 13(d) and 13(g) of the Securities Act.

Unless  otherwise  indicated,  the  address  of  each  beneficial  owner  listed  in  the  table  below  is  c/o  Innate 
Pharma S.A., 117, Avenue de Luminy – BP 30191, 13009 Marseille, France.

In  the  context  of  the  Nasdaq  IPO  and  regarding  the  need  to  put  in  place  insurance  for  the  liability  of 
officers of listed companies in the United States, the Supervisory Board  decided :

(i) 
to  subscribe  to  an  insurance  policy  covering  the  risks  associated  with  the  Nasdaq  IPO  (IPO 
insurance) and an insurance policy extension for companies listed on the Nasdaq (D&O insurance policy); 
and

to  enter  into  an  indemnification  agreement  between  the  Company  and  the  Supervisory  and 

(ii) 
Executive Board members.

Such  indemnification  agreement  provides  that  the  Company  would  cover  Supervisory  Board  members 
and  Executive  Board  members  in  situations  in  which  the  IPO  and  D&O  insurance  policies  would  not 
cover  them,  but  always  within  the  limits  of  what  is  legally  possible  in  terms  of  indemnification  of 
directors and officers.

Transaction with Related Companies 

From  time  to  time,  in  the  ordinary  course  of  its  business,  the  Company  may  contract  for  services  from 
companies  or  institutions  in  which  certain  members  of  its  Executive  Board  or  Supervisory  Board  may 
serve as a director or advisor. The cost and provision of these services are negotiated on an arm's-length 
basis, and none of these arrangements are material.

Related Person Transaction Policy 

The  Company  complies  with  French  law  regarding  approval  of  transactions  with  related  parties.  On 
September 12, 2019, the Supervisory Board adopted a related person transaction policy that sets forth its 
procedures  for  the  identification,  review,  consideration  and  approval  or  ratification  of  related  person 
transactions. The policy became effective immediately upon the execution of the underwriting agreement 
for  the  October  2019  global  offering.  For  purposes  of  its  policy  only,  a  related  person  transaction  is  a 
transaction,  arrangement  or  similar  contractual  relationship,  or  any  series  of  similar  transactions, 
arrangements  or  relationships,  in  which  the  Company  and  any  related  person  are,  were  or  will  be 
participants  and  the  amount  involved  in  the  transaction  exceeds  $120,000,  with  the  exception  of  usual 
transactions concluded under normal conditions. A related person is any member of the Executive Board 
or Supervisory Board or beneficial owner of more than 5% of any class of its voting securities, including 
any of their immediate family members and any entity owned or controlled by such persons. 

Under  the  policy,  if  a  transaction  has  been  identified  as  a  related  person  transaction,  including  any 
transaction that was not a related person transaction when originally consummated or any transaction that 
was not initially identified as a related person transaction prior to consummation, the management must 
present  information  regarding  the  related  person  transaction  to  the  Supervisory  Board  for  review, 
consideration  and  approval  or  ratification.  The  presentation  must  include  a  description  of,  among  other 
things, the material facts, the interests, direct and indirect, of the related persons, the benefits to Innate of 
the transaction and  whether the transaction is on terms that are comparable to the terms available to or 
from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, 
the Company will collect information that the Company deems reasonably necessary from each member 
of its Executive Board and Supervisory Board and, to the extent feasible, significant shareholder to enable 
Innate to identify any existing or potential related-person transactions and to effectuate the terms of the 
policy. 

In addition, under its Code of Business Conduct and Ethics, which Innate Pharma adopted on September 
12, 2019, its employees and Executive and Supervisory Board members have an affirmative responsibility 

199

to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of 
interest. 

In  considering  related  person  transactions,  the  Supervisory  Board  will  take  into  account  the  relevant 
available facts and circumstances including, but not limited to: 

•

•

•

•

the risks, costs and benefits to us; 

the impact on the independence of a member of the Executive Board or Supervisory Board in the 
event  that  the  related  person  is  a  member  of  the  Executive  Board  or  Supervisory  Board,  an 
immediate family member of a member of the Executive Board or Supervisory Board or an entity 
with which a member of Executive Board or Supervisory Board is affiliated; 

the availability of other sources for comparable services or products; and 

the terms available to or from, as the case may be, unrelated third parties or to or from employees 
generally. 

The policy requires that, in determining whether to approve, ratify or reject a related person transaction, 
the Supervisory Board must consider, in light of known circumstances, whether the transaction is in, or is 
not inconsistent with, the Company's best interests and those of its shareholders, as the Supervisory Board 
determines in the good faith exercise of its discretion. 

All of the transactions described above were evaluated and approved by the Supervisory Board.

Legal Proceedings

From  time  to  time,  the  Company  may  be  involved  in  various  claims  and  legal  proceedings  relating  to 
claims arising out of our operations. The Company is not currently a party to any legal proceedings that, 
in the opinion of our management, are likely to have a material adverse effect on our business. Regardless 
of  outcome,  litigation  can  have  an  adverse  impact  on  the  Company  because  of  defense  and  settlement 
costs, diversion of management resources and other factors.

Dividend Policy

The Company has never declared or paid any dividends on our ordinary shares. The Company does not 
anticipate paying cash dividends on our equity securities in the foreseeable future and intends to retain all 
available funds and any future earnings for use in the operation and expansion of our business, given our 
state of development. 

Subject to the requirements of French law and our bylaws, dividends may only be distributed from our 
distributable profits, plus any amounts held in our available reserves which are reserves other than legal 
and  statutory  and  revaluation  surplus.  Dividend  distributions,  if  any  in  the  future,  will  be  made  in  euro 
and converted into U.S. dollars with respect to the ADSs, as provided in the deposit agreement. See the 

200

Corporate Purpose (Article 4 of the Bylaws)

Our corporate purpose, directly or indirectly, in France or other countries is to:

•

•

carry out, on our own behalf or on behalf of third parties, any research, development, studies and 
development of manufacturing or marketing procedures for pharmaceutical products;

register or grant any patent or license directly or indirectly connected with our activity; and

• more  generally,  perform  any  operation  of  any  kind,  whether  economic,  legal,  financial,  civil  or 
commercial, which may be directly or indirectly related to our corporate purpose or any similar, 
associated or complementary purpose.

Executive Board (Articles 14 to 16 of the Bylaws)

The Executive Board is responsible for our management and is composed of a minimum of two members 
and  a  maximum  of  five  members  who  perform  their  duties  under  the  supervision  of  the  Supervisory 
Board.

Members of the Executive Board

The  members  of  the  Executive  Board  are  appointed  or  have  their  appointments  renewed  by  the 
Supervisory Board. The members of the Executive Board must be individuals. They are not required to be 
shareholders.  They  may  be  French  citizens  or  citizens  of  other  countries.  Members  of  the  Executive 
Board cannot be members of the Supervisory Board.

The  maximum  age  for  being  a  member  of  the  Executive  Board  And  the  limitations  on  having  such  an 
appointment concurrently with an appointment in another company are subject to the applicable legal and 
regulatory provisions.

The term of office for the members of the Executive Board is three years and may be renewed. If there is 
a vacancy, the Supervisory Board must fill the vacancy within two months. The replacement is appointed 
for the time remaining until the Executive Board is up for renewal.

The  members  of  the  Executive  Board  may  be  removed  from  office,  with  or  without  cause  and  without 
notice, by the Supervisory Board or at any General Meeting of shareholders, by a simple majority vote of 
the shareholders present and voting at the meeting in person or by proxy.

Chairman of the Executive Board

The Supervisory Board elects a Chairman from among the members of the Executive Board to serve for 
the  duration  of  his  appointment  as  a  member  of  the  Executive  Board.  The  Chairman  of  the  Executive 
Board represents us in our relations with third parties.

The  Supervisory  Board  may  assign  this  power  of  representation  to  one  or  more  other  members  of  the 
Executive Board. Assignees have the title of General Manager.

Meetings and Powers of the Executive Board

The Executive Board meets as often as is in our interest, but at least once per quarter. Meetings are called 
by the Chairman or a member of the Executive Board appointed for this purpose.

At least three-quarters of the members of the Executive Board must be effectively present to constitute a 
quorum  and  decisions  are  made  by  a  majority  of  the  members  of  the  Executive  Board  present  or 
represented. Each member has one vote. In case of equality of expressed votes either in favor or against a 
decision (abstentions are not taken into account), the Chairman of the Executive Board has a casting vote.

202

The Executive Board has broad power to act under all circumstances on our behalf. It exercises this power 
within the limits of our corporate purpose and subject to any powers expressly given to the Supervisory 
Board and Shareholders’ Meetings by law and according to our bylaws, and abiding by any restrictions on 
powers decided by the Supervisory Board. There are currently no limits imposed on the amounts of loans 
or borrowings that the Executive Board may approve.

Compensation of the Executive Board

The method and amount of compensation for each member of the Executive Board is determined by the 
Supervisory Board when appointing such member.

Supervisory Board (Articles 17 to 22 of the Bylaws)

Members of the Supervisory Board

The Executive Board is supervised by a Supervisory Board made up of a minimum of three members and 
a maximum of eighteen. The members of the Supervisory Board are appointed for a renewable term of 
two years at the General Meeting of shareholders, which may revoke their appointments at any time. The 
appointees are selected from among the shareholders and may be individuals or companies. Each member 
must  own  at  least  one  of  our  ordinary  shares  for  the  entire  term  of  the  appointment.  Members  of  the 
Supervisory Board cannot be members of the Executive Board.

The number of members of the Supervisory Board who have reached the age of seventy years cannot be 
higher than a third of the members of the Supervisory Board. If the age limitation is exceeded, the eldest 
member is deemed to have resigned automatically.

Chairman of the Supervisory Board

The Supervisory Board appoints from its members who are individuals a Chairman and a Vice-Chairman, 
who are in charge of convening the Supervisory Board and leading the debates.

Meetings and Powers of the Supervisory Board

The  Supervisory  Board  meets  as  often  as  is  in  our  interests  but  at  least  once  per  quarter.  Meetings  are 
called by the Chairman or Vice-Chairman, or by a member of the Executive Board or at least one-third of 
the members of the Supervisory Board, under the circumstances and according to the conditions set forth 
in the bylaws.

At  least  half  of  the  members  of  the  Supervisory  Board  must  be  present  to  constitute  a  quorum  and 
decisions  are  made  by  a  majority  of  the  members  of  the  Supervisory  Board  present  or  represented,  it 
being  specified  that  in  a  case  of  a  split-vote,  the  Chairman  of  the  Supervisory  Board  shall  have  the 
tiebreaking vote.

The  Supervisory  Board  exercises  permanent  control  over  our  management  by  the  Executive  Board  and 
the  powers  explicitly  conferred  on  it  by  the  French  laws.  It  alone  has  the  authority  to  authorize  certain 
significant transactions.

Under French law, any agreement entered into, directly or through an intermediary, between us and one 
of the members of the Executive Board or Supervisory Board, or a shareholder that holds over 10% of the 
voting rights, or, if such shareholder is a company, the controlling company thereof, must be subject to 
prior authorization from the Supervisory Board. The interested member cannot vote on such decision. The 
same  applies  to  agreements  in  which  a  person  referred  above  has  an  indirect  interest.  Such  prior 
authorization also applies to agreements between us and another company if one of the members of our 
Executive Board or Supervisory Board is the owner, a partner with unlimited liability, manager, director, 
managing director, member of the Executive Board or of the Supervisory Board, or, in a general manner 

203

is  in  a  position  of  responsibility  within  the  other  company.  These  provisions  are  not  applicable  to 
agreements concerning day-to-day operations entered into under normal conditions.

In a report to the General Meeting of shareholders attached to the Executive Board’s Management Report, 
the Supervisory Board reports on the conditions for preparing and organizing the work of the Supervisory 
Board as well as the internal control procedures set up by us.

Compensation of the Supervisory Board

Compensation  for  their  attendance  at  board  meetings  (formerly  known  as  jetons  de  emunera)  is 
determined at the annual ordinary General Meeting. The General Meeting of shareholders may allocate an 
annual  fixed  sum  and  our  Supervisory  Board  allocates  this  sum  among  its  members  as  it  sees  fit.  In 
addition, the Supervisory Board may allocate exceptional compensation (emuneration exceptionnelle) for 
missions or mandates entrusted to its members; in this case, this remuneration is subject to the provisions 
regarding related-parties agreements.

Committees

The Supervisory Board may decide to establish committees responsible for reviewing matters which the 
Supervisory Board or its Chairman wish to submit to them for examination and advice.

Observers (Article 23 of the Bylaws)

at  the  General  Meeting  of  shareholders,  one  or  more  observers  (censeurs)  may  be  appointed,  at  the 
discretion of the shareholders for a term of office expiring at the shareholders meeting convened to decide 
on  the  financial  statements  for  the  preceding  financial  year  after  the  first  anniversary  date  of  their 
appointment. This mandate is renewable without limit. Observers may be individuals or companies and 
are not required to be shareholders. 

The observers attend all Supervisory Board meetings, with the right to participate but with a consultative 
vote  only.  They  hold  the  same  information  and  communication  rights  than  the  Supervisory  Board’s 
members and they are bound to the same confidentiality obligations.

General Meeting of Shareholders (Articles 26 to 37 of the Bylaws)

Calling Meetings and Conditions for Admission (Articles 27 to 30 of the Bylaws)

General Meetings of shareholders are called by the Executive Board, or failing that, by the Supervisory 
Board. They can also be called by the auditor(s) or an officer appointed by a court upon request, by any 
interested party or by the Works Council in an emergency, by one or more shareholders holding at least 
five  percent  of  the  ordinary  shares  or  by  an  association  of  our  shareholders.  Meetings  are  held  at  our 
registered offices or at any other location indicated in the convening notice.

The  meeting  is  published  in  the  French  Bulletin  of  Mandatory  Legal  Notices  (Bulletin  des  Annonces 
Légales Obligatoires or BALO) at least 35 days prior to the date of a General Meeting of shareholders. In 
addition  to  the  information  concerning  us,  the  notice  indicates  in  particular  the  agenda  of  the  General 
Meeting of shareholders and the draft resolutions that will be presented.

In  the  21  days  preceding  the  meeting,  we  will  publish  the  information  and  documents  relating  to  the 
meeting on our website.

The General Meeting of shareholders must be announced at least 15 days beforehand, by a notice placed 
in a journal that publishes legal announcements in the department where the headquarters are located, and 
in the BALO. Holders of registered shares who have owned them for at least one month as of the date on 
which the latest notice is published receive individual notices. When a General Meeting of shareholders is 

204

unable to take action because the requisite quorum is not present, a second meeting is called at least ten 
days in advance using the same procedure as the first one.

The  General  Meeting  of  shareholders  may  only  take  action  on  items  on  the  agenda.  However,  it  may 
dismiss  and  replace  one  or  more  members  of  the  Supervisory  Board  at  any  time.  The  General  Meeting 
may also dismiss the members of the Executive Board. One or more shareholders representing at least the 
percentage  of  share  capital  fixed  by  law,  and  acting  according  to  the  legally  required  conditions  and 
deadlines, are allowed to request that items and/or draft resolutions be added to the agenda of the General 
Meeting of shareholders.

Each shareholder has the right to attend the meetings and take part in deliberation (i) personally; (ii) by 
granting proxy to another shareholder, his or her spouse or partner in a civil union or any other natural or 
legal  person  of  his  or  her  choice;  (iii)  by  sending  a  proxy  to  the  Company  without  indication  of  the 
beneficiary;  (iv)  by  voting  by  correspondence;  or  (v)  by  videoconference  or  another  means  of 
telecommunication,  including  internet,  in  accordance  with  applicable  laws  and  regulations  that  allow 
identification; by presenting proof of identity and ownership of shares, subject to:

•

•

for  holders  of  registered  shares,  an  entry  in  the  shareholder  registry  at  least  two  business  days 
before the General Meeting of shareholders; and

for  holders  of  bearer  shares,  filing,  under  the  conditions  provided  by  law,  of  a  certificate  of 
participation  issued  by  an  authorized  intermediary  two  business  days  before  the  date  of  the 
General Meeting of shareholders.

The final date for returning voting ballots by correspondence is set by the Executive Board and disclosed 
in the notice of meeting published in the BALO. This date cannot be earlier than three days prior to the 
meeting as provided in the bylaws.

A  shareholder  who  has  voted  by  correspondence  will  no  longer  be  able  to  participate  directly  in  the 
meeting or to be represented. In the case of returning the proxy form and the voting by correspondence 
form, the proxy form is taken into account, subject to the votes cast in the voting by correspondence form.

A shareholder may be represented at meetings by any individual or legal entity by means of a proxy form 
which we send to such shareholder either at the shareholder’s request or at our initiative. A shareholder’s 
request for a proxy form must be received at the registered office at least five days before the date of the 
meeting. The proxy is only valid for a single meeting, for two meetings (an ordinary and an extraordinary 
meeting convened for the same day or within 15 days) or for successive meetings convened with the same 
agenda.

A  shareholder  may  vote  by  correspondence  by  means  of  a  voting  form,  which  we  send  to  such 
shareholder either at the shareholder’s request or at our initiative, or which we include in an appendix to a 
proxy voting form under the conditions provided for by current laws and requirements. A shareholder’s 
request for a voting form must be received at the registered office at least six days before the date of the 
meeting. The voting form is also available on our website at least 21 days before the date of the meeting. 
The voting by correspondence form addressed by a shareholder is only valid for a single meeting or for 
successive meetings convened with the same agenda.

Strategic Collaborations and License Agreements 

AstraZeneca

2015 Agreements

In April 2015, the Company entered into two agreements with MedImmune, a wholly owned subsidiary 
of  AstraZeneca,  which  Innate  refers  to  as  AstraZeneca.  The  first  agreement  was  a  co-development  and 
license agreement relating to certain combination products containing monalizumab ( the "Original Co-
Development  Agreement"),  and  the  second  agreement  was  a  development  and  option  agreement  for 
products  containing monalizumab, including products using monalizumab as a monotherapy (the  "2015 
Option Agreement"). The Company received an initial payment of $250 million under these agreements 
on  June  30,  2015,  of  which  $100  million  was  paid  to  Innate  as  an  initial  payment  for  the  Original  Co-
Development  Agreement  and  $150  million  was  paid  to  Innate  as  consideration  for  the  2015  Option 
Agreement  described  below.  In  October  2018,  AstraZeneca  exercised  its  option  under  the  2015  Option 
Agreement, which resulted in the automatic termination of both the Original Co-Development Agreement 
and the 2015 Option Agreement, and a new co-development and license agreement relating to all products 
containing  monalizumab  (the  "2015  Co-Development  Agreement"),  automatically  came  into  effect.  In 
connection  with  AstraZeneca’s  exercise  of  its  option  under  the  2015  Option  Agreement,  an  upfront 
payment of $100 million was due under the 2015 Co-Development Agreement, which it paid in January 
2019.

2015 Co-Development Agreement (monalizumab)

Under  the  2015  Co-Development  Agreement,  the  Company  granted  to  AstraZeneca  a  worldwide, 
exclusive  license,  subject  to  certain  exclusions,  to  certain  of  its  patents  and  know-how  to  develop, 
manufacture  and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis, 
prevention  and  treatment  of  oncology  diseases  and  conditions.  The  Company  further  granted  to 
AstraZeneca  a  worldwide,  non-exclusive  license  to  certain  of  its  other  patents  to  develop,  manufacture 
and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis,  prevention  and 
treatment of oncology diseases and conditions. The Company retains the rights under the licensed patents 
in  certain  European 
and  know-how 
countries,pursuant to its option to co-promote, and exploit the licensed patents and know-how to research, 
develop  and  commercialize  the  licensed  products  outside  of  the  field  of  diagnosis,  prevention  and 
treatment of oncology diseases and conditions.

things,  co-promote 

licensed  products 

to,  among  other 

Under the 2015 Co-Development Agreement, the Company is required to collaborate with AstraZeneca to 
develop  and  commercialize  licensed  products.  AstraZeneca  will  be  the  lead  party  in  developing  the 
licensed  products  and  licensed  product  in  certain  major  markets.  Each  party  will  have  to  use 
commercially reasonable efforts to complete certain development activities in accordance with a specified 
development plan.

The  Company  is  required  for  a  defined  period  of  time  to  co-fund  30%  of  the  Phase  3  clinical  trials  of 
licensed products, subject to an aggregate cap, in order to receive 50% of the profits in Europe.

On  July  31,  2019,  the  Company  notified  AstraZeneca  of  its  decision  to  co-fund  future  monalizumab 
Phase 3 clinical development program. In October 2020, AstraZeneca enrolled the first patient in the first 
Phase 3 trial which triggered a $50 million milestone payment from AstraZeneca to Innate.

In August 2022, the Company announced that the planned futility interim analysis of the INTERLINK-1 
Phase 3 study sponsored by AstraZeneca did not meet a pre-defined threshold for efficacy.  Based on this 

206

result and the recommendation of an Independent Data Monitoring Committee, AstraZeneca has informed 
Company that the study will be discontinued.

In  September  2021,  AstraZeneca,  based  on  data  from  the  randomized  Phase  2  trial  in  patients  with 
unresectable,  Stage  III  non-small  cell  lung  cancer  (NSCLC)  presented  at  the  European  Society  for 
Medical Oncology (ESMO) Congress, announced plans to initiate a Phase 3 trial for both combinations of 
monalizumab  or  oleclumab  plus  durvalumab  in  the  unresectable,  Stage  III  NSCLC  setting  for  patients 
who had not progressed after concurrent chemoradiationtherapy.

In  April  2022,  the  Company  announced  that  AstraZeneca  enrolled  the  first  patient  in  a  second  Phase  3 
trial,  PACIFIC-9,  evaluating  durvalumab  in  a  combination  with  monalizumab  or  oleclumab  in  patients 
with unresectable, Stage III NSCLC, which trigerred a  $50 million milestone payment from AstraZeneca 
Innate.

Separately,  AstraZeneca  also  announced  that  it  is  starting  a  Phase  2  clinical  trial,  NeoCOAST-2,  that 
includes  a  treatment  arm  with  durvalumab  in  combination  with  chemotherapy  and  monalizumab  in 
resectable, early-stage NSCLC.

AstraZeneca  will  be  responsible  for  the  promotion  of  licensed  products  worldwide,  subject  to  Innate's 
option to co-promote the licensed products in certain European countries. Should the Company elect not 
to co-promote, its share of profits in Europe will be reduced by a specified amount of percentage points 
not to exceed the mid-single digits.

The  development  by  AstraZeneca  of  a  licensed  product  under  the  2015  Co-Development  Agreement  is 
subject to certain reciprocal non-compete obligations.

AstraZeneca  is  obligated  to  pay  Innate  up  to  $775  million  in  the  aggregate  upon  the  achievement  of 
certain  development  and  regulatory  milestones  ($350million),  and  commercialization  milestones  ($425 
million). As described above, the arrangement also provides for a 50% profit share and, subject to certain 
deferrals of reimbursement, loss share of licensed products in Europe if the Company does not opt out of 
its co-funding and co-promoting obligations. In addition, the Company will be eligible to receive tiered 
royalties ranging from a low double-digit to mid-teen percentage on net sales of licensed products outside 
of Europe. The royalties payable to Innate under the 2015 Co-Development Agreement may be reduced 
under certain circumstances, including loss of exclusivity or lack of patent protection.

Innate's  right  to  receive  royalties  under  the  2015  Co-Development  Agreement  expires,  on  a  licensed 
product-by-licensed product and country-by-country basis, on the latest of: (i) the tenth anniversary of the 
first commercial sale of such licensed product in such country, or in the case of European countries, in 
any  European  country,  (ii)  the  expiration  of  regulatory  exclusivity  for  such  licensed  product  in  such 
country and (iii) the expiration of the last-to-expire valid licensed patent claim subject to the agreement 
that covers such licensed product in such country.

Unless  earlier  terminated,  the  term  of  the  2015  Co-Development  Agreement  will  expire  on  the  date  on 
which all of AstraZeneca’s payment obligations have expired. The Company may terminate the 2015 Co-
Development  Agreement  if  AstraZeneca  challenges  any  patent  licensed  to  it  under  the  agreement. 
AstraZeneca may terminate the 2015 Co-Development Agreement in its entirety for convenience at any 
time  effective  upon  120  days’  prior  written  notice  to  us.  Either  party  may  terminate  the  2015  Co-
Development  Agreement  in  the  event  of  an  uncured  material  breach  by  the  other  party  or  for  certain 
bankruptcy or insolvency events involving the other party.

If the 2015 Co-Development Agreement is terminated by AstraZeneca for convenience or by Innate for 
AstraZeneca’s material breach, insolvency or a patent challenge by AstraZeneca, all licenses and rights 
granted  under  the  agreement  terminate,  however,  upon  any  such  termination,  AstraZeneca  would  grant 
Innate  an  exclusive,  worldwide,  royalty-bearing  right  and  license,  with  the  right  to  grant  sublicenses, 

207

under  technology  developed  by  AstraZeneca  and  incorporated  into  or  necessary  for  the  exploitation  of 
licensed products, except for certain manufacturing technology that would require a separate agreement. 
If  the  2015  Co-Development  Agreement  is  terminated  by  AstraZeneca  for  Innate's  material  breach  or 
insolvency,  AstraZeneca  has  the  right  to  continue  the  agreement  by  providing  written  notice  to  us.  If 
AstraZeneca provides Innate with such written notice, among other things, its rights under the co-promote 
option will terminate and the Company must cease any development, manufacture or commercialization 
activities under the agreement.

Collaboration and Option Agreement with AstraZeneca relating to CD39 

In  October  2018,  the  Company  entered  into  a  collaboration  and  option  agreement  relating  to  IPH5201. 
The Company received an initial payment of $50 million under this agreement, $26 million of which was 
received in October 2018 and $24 million of which was received in January 2019. Pursuant to the 2018 
CD39  Option  Agreement,  the  Company  granted  to  AstraZeneca  an  exclusive  option  to  obtain  an 
exclusive license to certain of its patents and know-how to develop and commercialize licensed products, 
including IPH5201 in the field of the diagnosis, prevention and treatment of all diseases and conditions in 
humans or animals, subject to certain limitations. 

Under  the  2018  CD39  Option  Agreement,  the  Company  must  collaborate  with  AstraZeneca  to  develop 
CD39  option  products.  Prior  to  the  expiration  of  the  option  period,  the  Company  and  AstraZeneca  are 
subject to certain non-compete obligations. 

AstraZeneca  is  responsible  for  funding  the  research  and  development  costs  of  CD39  option  products 
contemplated in the joint development plan. Additionally, the Company may conduct certain exploratory 
clinical studies at its own cost, subject to reimbursement by AstraZeneca with a premium under certain 
circumstances related to subsequent development by AstraZeneca. 

Following  the  dosing  of  the  first  patient  on  March  9,  2020  in  the  IPH5201  Phase  1  clinical  trial, 
AstraZeneca made a $5 million milestone payment to Innate. 

In  June  2022,  the  2018  CD39  Option  Agreement  was  amended.  Innate  received  a  $5  million  milestone 
payment  from  AstraZeneca  upon  signature  of  the  amendment  and  is  responsible  for  conducting  a  new 
Phase  2  multicenter,  open  label,  non-randomized  study  of  neoadjuvant  and  adjuvant  treatment  with 
IPH5201,  durvalumab  and  chemotherapy  in  patients  with  resectable,  early-stage  non-small  cell  lung 
cancer (NSCLC). The "MATISSE" Study has started. AstraZeneca and Innate will share study costs and 
AstraZeneca  will  supply  clinical  trial  drugs.  Innate  made  a  €0.6  million  milestone  payment  to  Orega 
Biotech SAS pursuant to Innate’s exclusive licensing agreement (see below).  

On  June  26,  2023,  the  Company  announced  the  first  patient  was  dosed  in  MATISSE,  a  Phase  2 
multicenter  single-arm  study  (NCT05742607),  sponsored  by  the  Company,  evaluating  neoadjuvant  and 
adjuvant  treatment  with  IPH5201,  an  anti-CD39  blocking  monoclonal  antibody,  in  combination  with 
durvalumab (anti-PD-L1) and chemotherapy, in treatment-naïve patients with resectable early stage non-
small cell lung cancer (NSCLC). The primary objectives of the study are to assess antitumor activity of 
neoadjuvant  treatment  based  on  pathological  complete  response  (pCR)  and  safety.  The  Company  is 
responsible  for  conducting  the  study  and  shares  study  costs  with  AstraZeneca.  AstraZeneca  supplies 
clinical  trial  drugs.  More  information  about  the  Phase  2  MATISSE  trial,  see  “Item  4.B—Business 
Overview—IPH5201,  an  Anti-CD39  Antibody  Targeting  the  Immunosuppressive  Adenosine  Pathway.” 
The Company received a $5 million milestone payment from AstraZeneca when the decision was made to 
progress IPH5201 to a Phase 2 clinical trial.

208

Unless  earlier  terminated,  the  term  of  the  2018  CD39  Option  Agreement  will  expire  on  the  earlier  of 
exercise of the option or expiration of the option period in the event that AstraZeneca does not exercise 
the  option.  The  Company  may  terminate  the  2018  CD39  Option  Agreement  if  AstraZeneca  challenges 
any  option  patent.  AstraZeneca  may  terminate  the  2018  CD39  Option  Agreement  in  its  entirety  for 
convenience  at  any  time  effective  upon  three  months’  prior  written  notice  to  us.  Either  party  may 
terminate the 2018 CD39 Option Agreement in the event of an uncured material breach by the other party 
or for certain bankruptcy or insolvency events involving the other party. 

CD39 Co-Development and License Agreement Upon Option Exercise by AstraZeneca

license  agreement  with  AstraZeneca,  or 

Upon exercise of the option under the 2018 CD39 Option Agreement, the Company would enter into a 
the  CD39  Potential  License 
co-development  and 
Agreement.Under  the  CD39  Potential  License  Agreement,  the  Company  would  grant  to  AstraZeneca  a 
worldwide,exclusive  license,  subject  to  certain  exclusions,  to  certain  of  its  patents  and  know-how 
regarding,  among  other  things,  its  IPH5201  candidate,  to  develop,  manufacture  and  commercialize 
licensed products in the field of diagnosis, prevention and treatment of diseases and conditions in humans 
and in animals, subject to certain limitations. The Company would retain certain rights under the licensed 
patents  and  know-how  to,  among  other  things,  co-promote  licensed  products  in  certain  European 
countries, pursuant to its option to co-promote.

The  CD39  Potential  License  Agreement  provides  for  a  payment  of  $25  million  upon  exercise. 
Additionally, AstraZeneca would be obligated to pay Innate up to $795 million in the aggregate upon the 
achievement  of  certain  development  and  regulatory  milestones  ($295  million)  and  commercialization 
milestones  ($500  million).  The  arrangement  also  provides  for  a  50%  profit  share  in  Europe  if  the 
Company opts into certain co-promoting and late stage co-funding obligations. In addition, the Company 
would be eligible to receive tiered royalties ranging from a high-single digit to mid-teen percentage on net 
sales of IPH5201, or from a mid-single digit to low-double digit percentage on net sales of other types of 
licensed products, outside of Europe. The royalties payable to Innate under the CD39 Potential License 
Agreement  may  be  reduced  under  certain  circumstances,  including  loss  of  exclusivity  or  lack  of  patent 
protection.

Under  the  CD39  Potential  License  Agreement,  unless  the  Company  has  elected  not  to  co-fund,  the 
Company  would  be  required  to  collaborate  with  AstraZeneca  to  develop  and  commercialize  licensed 
products. AstraZeneca would be the lead party in developing and commercializing the licensed products 
and  each  party  must  use  commercially  reasonable  efforts  to  develop,  obtain  regulatory  approval  and 
commercialize  at  least  one  licensed  product  in  certain  major  markets.  Each  party  would  have  to  use 
commercially  reasonable  efforts  to  complete  its  development  activities  in  accordance  with  a  specified 
development plan.

The Company would have the option to co-fund 30% of the Phase 3 clinical trials of licensed products in 
order to share in 50% of the profits and losses of licensed products in Europe. If the Company does not 
exercise this co-funding option, among other things, its right to share in 50% of the profits and losses in 
Europe and right to co-promote in certain European countries will terminate and will be replaced by rights 
to  receive  royalties  on  net  sales  at  the  rates  applicable  to  outside  of  Europe.  Additionally,  certain 
milestone payments that may be payable to Innate would be reduced. AstraZeneca would be responsible 
for  the  promotion  of  licensed  products  worldwide,  subject  to  its  option  to  co-promote  the  licensed 
products  in  certain  European  countries  if  the  Company  elects  to  co-fund.  Additionally,  the  Company 
would have a right of first negotiation in the event that AstraZeneca wishes to grant a third-party the right 
to commercialize licensed products in Europe or the United States.

209

The development by AstraZeneca of a licensed product under the Potential License Agreement is subject 
to certain reciprocal non-compete obligations.

Innate's  right  to  receive  royalties  under  the  CD39  Potential  License  Agreement  expires,  on  a  licensed 
product-by-licensed product and country-by-country basis, on the latest of: (i) the tenth anniversary of the 
first commercial sale of such licensed product in such country, or, in the case of European countries, in 
any  European  country,  (ii)  the  expiration  of  regulatory  exclusivity  for  such  licensed  product  in  such 
country and (iii) the expiration of the last-to-expire valid licensed patent claim subject to the agreement 
that covers such licensed product in such country.

Unless earlier terminated, the term of the CD39 Potential License Agreement would expire on the date on 
which  all  of  AstraZeneca’s  payment  obligations  have  expired.  The  Company  may  terminate  the  CD39 
Potential  License  Agreement  if  AstraZeneca  challenges  any  patent  licensed  to  it  under  the 
agreement.AstraZeneca  may  terminate  the  CD39  Potential  License  Agreement  in  its  entirety  for 
convenience at any time effective upon 120 days’ prior written notice to us. Either party may terminate 
the CD39 Potential License Agreement in the event of an uncured material breach by the other party or 
for certain bankruptcy or insolvency events involving the other party.

2018 Future Programs Option Agreement

In October 2018, the Company entered into another option agreement with AstraZeneca, relating to four 
pre-clinical programs. The Company received an initial payment of $20 million at signing. Pursuant to the 
2018  Future  Programs  Option  Agreement,  the  Company  granted  to  AstraZeneca  four  exclusive  options 
that  were  exercisable  until  IND  approval  to  obtain  a  worldwide,  royalty-bearing,  exclusive  license  to 
certain  of  its  patents  and  know-how  relating  to  certain  specified  pipeline  candidates  to  develop  and 
commercialize  optioned  products  in  all  fields  of  use.  In  2022,  the  Company  has  received  from 
AstraZeneca a notice that it will not exercise its option to license the four pre-clinical programs covered in 
the Future Programs Option Agreement which is therefore terminated.

Termination and Transition Agreement with AstraZeneca relating to Lumoxiti

In  October  2018,  the  Company  entered  into  an  agreement  with  AstraZeneca  relating  to  the  license  of 
lumoxiti, or the Lumoxiti Agreement.

The  Company  made  an  initial  payment  to  AstraZeneca  of  $50  million  under  this  agreement  in  January 
2019 as well as $15 million when filing of the BLA in Europe. Pursuant to the Lumoxiti Agreement, the 
Company obtained an exclusive license under certain patents and know-how of AstraZeneca to develop, 
manufacture  and  commercialize  Lumoxiti  for  all  uses  in  humans  and  animals  in  the  United  States,  the 
European Union and Switzerland.  In December 2020, the Company exercised its right of termination of 
the Lumoxiti Agreement by sending a termination notice to AstraZeneca.

Further  to  the  decision  to  terminate  the  Lumoxiti  Agreement  and  termination  notice  sent  in  December 
2020,  a  termination  and  transition  agreement,  or  the  Termination  and  Transition  Agreement,  was 
executed, effective as of June 30, 2021 organizing the transition of the licensed rights and BLA back to 
AstraZeneca and a share of different costs including manufacturing.  As provided by the termination and 
transition  agreement,  Innate  paid  $6.2  million  to  AstraZeneca  on  April  29,  2022.  Transition  of  all 
Lumoxiti rights back to AstraZeneca was completed in July 2022.

Novo Nordisk A/S 

Development and License Agreement relating to monalizumab

On  February  5,  2014,  the  Company  in-licensed  the  full  development  and  commercialization  rights  to 
monalizumab from Novo Nordisk A/S. In consideration for these rights, the Company paid Novo Nordisk 
A/S €2 million in cash and 600,000 of its ordinary shares at a price of €8.33 per share. Novo Nordisk A/S 
is  eligible  to  receive  a  total  of  €20  million  in  potential  regulatory  milestones  and  tiered  mid-to-high 
single-digit percentage royalties on future net sales.

The agreement with Novo Nordisk A/S included a right to additional consideration in the event of an out-
licensing agreement. Consequently, following the agreement signed with AstraZeneca in April 2015, the 
Company paid Novo Nordisk A/S an additional consideration amount of €6.5 million. 

In  October  2018  AstraZeneca  exercised  its  option  under  the  2015  Option  Agreement  to  acquire  an 
exclusive  license  to  monalizumab.  Pursuant  to  this  option  exercise,  AstraZeneca  paid  $100  million  to 
Innate and, as a result, Novo Nordisk A/S became entitled to a second and final payment amounting to 
$15.0 million (€13.1 million). If the AstraZeneca agreement is terminated for any reason, the Company 
will pay to Novo Nordisk A/S a portion of any amounts that have been budgeted but have not been spent 
or  will  not be spent  under  the initial research and development budget. In light of current development 
plans and research and development costs incurred to date, the Company does not currently expect any 
amounts to be paid pursuant to this provision. 

License Agreement relating to avdoralimab  

In July of 2017 the Company entered into an exclusive license agreement with Novo Nordisk A/S relating 
to  avdoralimab,  or  the  2017  Novo  Agreement,  pursuant  to  which  the  Company  obtained  a  worldwide, 
exclusive license under certain patents and know-how of Novo Nordisk A/S to develop, manufacture and 
commercialize pharmaceutical products that contain or comprise an Anti-C5aR antibody. The Company 
made an initial payment to Novo Nordisk A/S of €40.0 million under the 2017 Novo Agreement which 
was  offset  against  Novo  Nordisk  A/S’s  subscription  in  new  shares.  The  Company  is  obligated  to  pay 
Novo  Nordisk  A/S  in  the  aggregate  up  to  €370.0  million  upon  achievement  of  certain  development, 
regulatory  and  sales  milestones  and  tiered  royalties  ranging  from  a  low  double-digit  to  low  teen 
percentage on net sales. The Company's royalty payment obligations are subject to certain reductions and 
expire on a product-by-product and country-by-country basis upon the later of the date the exploitation of 
a licensed product is no longer covered by a claim of a licensed patent in such country, loss of data or 
regulatory  exclusivity  in  such  country,  and  the  twelfth  anniversary  of  the  first  commercial  sale  of  such 
product  in  such  country.  In  connection  with  the  2017  Novo  Agreement,  the  Company  obtained  an 
exclusive  sublicense  from  Novo  Nordisk  A/S  under  certain  third-party  intellectual  property  rights.  In 
consideration for such sublicense, the Company may be obligated to pay a mid-single digit royalty on its 
net  sales  of  a  licensed  product,  however,  the  Company  will  be  entitled  to  offset  such  payments  against 
royalties payable to Novo Nordisk A/S. 

Under  the  2017  Novo  Agreement,  the  Company  is  obligated  to  use  commercially  reasonable  efforts  to 
develop and seek regulatory approval for a licensed product. 

The 2017 Novo Agreement shall expire upon expiration of the last royalty payment obligation under the 
agreement. Either party may terminate the 2017 Novo Agreement upon any uncured material breach of 
the  agreement  by  the  other  party  or  upon  a  bankruptcy  or  insolvency  of  the  other  party.  Additionally, 
Novo Nordisk A/S may terminate the agreement in the event the Company challenges any patent licensed 
under the agreement. The Company may terminate the 2017 Novo Agreement upon prior notice to Novo 
Nordisk A/S. 

211

In  2020,  the  Company  made  a  payment  to  Novo  Nordisk  A/S  of  €1  million  under  the  2017  Novo 
Agreement, covered by BPI funding, in respect of the start of a Phase 2 clinical trial of avdoralimab in 
COVID-19  patients  with  severe  pneumonia.  In  July  2021,  based  on  the  Phase  2  clinical  trial  of 
avdoralimab  in  COVID-19  patients  with  severe  pneumonia,  results  of  which  did  not  meet  its  primary 
endpoints  in  all  three  cohorts  of  the  trial,  the  Company  has  stopped  stop  exploring  avdoralimab  in 
COVID-19. 

Following  a  strategic  review  in  2021,  the  Company  was  solely  pursuing  avdoralimab  in  bullous 
pemphigoid  ("BP"),  an  inflammatory  disease,  through  an  investigator-sponsored  study  and  stopped 
further development in all other indications. 

In last quarter of 2022, the Company was informed by the Sponsor, the Centre Hospitalier Universitaire 
de Nice, that the ongoing Phase 2 study for the treatment of BP will be discontinued. Consequently, the 
Company decided to stop further development in BP indication and will continue to review its strategy on 
avdoralimab.

Sanofi

Collaboration and Licensing agreement (2016) - IPH6101 and IPH6401

The Company entered into a research collaboration and licensing agreement with Sanofi in January 2016 
to apply its proprietary technology to the development of bispecific antibody formats engaging NK cells 
to kill tumor cells through the activating receptor NKp46. The Company granted to Sanofi under certain 
of  its  intellectual  property  a  non-exclusive,  worldwide,  royalty-free  research  license,  as  well  as  an 
exclusive,  worldwide  license  to  research,  develop  and  commercialize  products  directed  against  two 
specified targets, for all therapeutic, prophylactic and diagnostic indications and uses. 

The Company will work together with Sanofi on the generation and evaluation of up to two bispecific NK 
cell engagers, using its technology and Sanofi’s tumor targets. Under the terms of the license agreement, 
Sanofi  will  be  responsible  for  the  development,  manufacturing  and  commercialization  of  products 
resulting  from  the  research  collaboration.  The  Company  will  be  eligible  for  up  to  €400.0  million  in 
payments,  primarily  upon  the  achievement  of  development  and  commercial  milestones,  as  well  as 
royalties ranging from a mid to high single-digit percentage on net sales.

On  January  5,  2021,  the  Company  announced  that  Sanofi  has  made  the  decision  to  progress  IPH6101/
SAR443579  into  investigational  new  drug  (IND)  enabling  studies.  IPH6101/SAR443579  is  a  NKp46-
based NK cell engager (NKCE) using Innate’s proprietary multi-specific antibody format. The decision 
triggered a €7 million milestone payment from Sanofi to Innate. Sanofi will be responsible for all future 
development,  manufacturing  and  commercialization  of  IPH6101/SAR443579.  Additionally,  in  January 
2021,  a  GLP-toxicology  study  was  initiated  for  the  IPH6101/SAR443579  program.  In  December  2021, 
the Company announced that the first patient was dosed in a Phase 1/2 clinical trial, evaluating IPH6101/
SAR443579,  in  patients  with  relapsed  or  refractory  acute  myeloid  leukemia  (R/R  AML),  B-cell  acute 
lymphoblastic  leukemia  (B-ALL)  or  high  risk-myelodysplastic  syndrome  (HR-MDS).  The  start  of  the 
trial  has  triggered  a  milestone  payment,  part  of  the  €400.0  million  mentioned  above.  The  Company 
received  €3.0m  from  Sanofi  following  the  initiation  of  a  GLP-tox  Study  and  the  launching  of  the    first 
Phase 1 clinical trial in humans in relapsed of refractory AML with IPH6101/SAR443579, respectively in 
January and December 2021.

In July 2022, the Company announced that Sanofi has made the decision to progress IPH6401/SAR’514 
into investigational new drug (IND) enabling studies, triggering a €3 million milestone payment.

On July 11, 2023, the Company announced that the first patient was dosed in a Sanofi-sponsored Phase 
1/2  clinical  trial  (NCT05839626),  evaluating  SAR’514  /  IPH6401  in  relapsed/refractory  multiple 

212

myeloma  (RRMM)  and  Relapsed/Refractory  Light-chain  Amyloidosis  (RRLCA).  SAR’514  is  a 
trifunctional  anti-BCMA  NKp46xCD16  NK  cell  engager,  using  Sanofi’s  proprietary  CROSSODILE® 
multi-functional  platform,  which  comprises  the  Cross-Over-Dual-Variable-Domain  (CODV)  format.  It 
induces  a  dual  targeting  of  the  NK  activating  receptors,  NKp46  and  CD16,  for  an  optimized  NK  cell 
activation,  based  on  the  Company’s  ANKET®  proprietary  platform.  The  purpose  of  the  dose  escalation 
and  dose  expansion  study  is  to  evaluate  the  safety,  pharmacokinetics  and  preliminary  efficacy  of 
SAR’514  in  monotherapy  in  patients  with  RRMM  and  RRLCA.  The  start  of  the  trial  has  triggered  a 
milestone payment from Sanofi to Innate, which is part of a previously announced research collaboration 
with Sanofi. More information about the Phase 1/2 trial, see “Item 4.B—Business Overview—IPH6401/
SAR’514, a BCMA-targeting NK Cell Engager.”

Research Collaboration and Licensing agreement (2022) relating to Innate’s ANKET® program - 
IPH62 and IPH67 

In  December  2022,  the  Company  entered  into  a  research  collaboration  and  licensing  agreement  with 
Genzyme Corporation, a wholly owned subsidiary of Sanofi under which the Company grants Sanofi an 
exclusive license to Innate’s B7H3 ANKET® program (IPH62) and options for two additional targets to 
be named. Upon candidate selection, Sanofi will be responsible for all development, manufacturing and 
commercialization. 

Under the terms of the research collaboration and license agreement, Innate has received in March 2023 
€25  million  as  upfront  payment  and  will  receive,  during  the  term  of  the  Research  and  Collaboration 
Agreement,  up  to  €1.35  billion  total  in  preclinical,  clinical,  regulatory  and  commercial  milestones  plus 
royalties on potential net sales.  

On December 19, 2023, Innate announced that Sanofi had exercised its option to license a natural killer 
(NK) cell engager program in solid tumors from the Company’s ANKET® platform (IPH67) pursuant to 
the  terms  of  the  research  collaboration  and  license  agreement  signed  in  December  2022.  Following  a 
research  collaboration  period,  Sanofi  will  be  responsible  for  all  development,  manufacturing  and 
commercialization.  Sanofi  still  retains  the  option  to  one  additional  ANKET®  target  as  per  the  research 
collaboration  and  licensing  agreement  with  Genzyme  Corporation.  Under  the  terms  of  the  research 
collaboration and licensing agreement, the Company has received a €15 million payment for the exercise 
of this option. The Company is eligible for up to €1.35 billion total in preclinical, clinical, regulatory and 
commercial milestones plus royalties on potential net sales.

Orega

Orega License Agreement with Orega relating to IPH5201

Pursuant  to  its  licensing  agreement  with  Orega  Biotech,  Innate  acquired  an  exclusive  license  to  Orega 
Biotech’s  intellectual  property  rights  relating  to  its  anti-CD39  checkpoint  inhibitor  program.  As  of 
December  31,  2018,  the  Company  had  paid  a  total  amount  of  €1.8  million  to  Orega  Biotech  for  the

On  July  17,  2017,  the  Company  entered  into  one  loan  agreement  with  Société  Générale,  pursuant  to 
which the Company obtained a financing in an amount equal to €15.2 million with a term of 12 years.

On December 22, and December 17, 2021, the Company entered into two loan agreements with Société 
Générale and BNP Paribas, respectively, pursuant to which the Company obtained non-dilutive financing 
in an aggregate amount equal to €28.7 million. 

The two loans have an initial term of one year with an extension up to five years at Innate’s option. They 
are 90% guaranteed by the French state (“PGE”) as part of the package of measures put in place by the 
French government to support companies during the COVID-19 pandemic. 

In  August  2022,  the  Company  requested  the  extension  of  these  two  loans  repayment  for  an  additional 
period  of  five  years  starting  in  2022  and  including  a  one-year  grace  period  (2023).  Consequently,  the 
Company has obtained agreements from Société Générale and BNP Paribas. The effective interest rates 
applied  to  these  contracts  during  the  additional  period  are  1.56%  and  0.95%  for  Société  Générale  and 
BNP Paribas loans, respectively, excluding insurance and guarantee fees, with an amortization exemption 
for  the  entire  year  2023.  During  this  grace  period,  the  Company  was  only  liable  for  the  payment  of 
interest and the guarantee fees, with amortization of the two loans starting in 2024 over a period of four 
years. 

The  summaries  provided  above  do  not  purport  to  be  complete  and  are  qualified  in  their  entirety  by 
reference to the complete agreements, which are attached as exhibits to this Annual Report on Form 20-F.

Exchange Controls.

Under  current  French  foreign  exchange  regulations  there  are  no  restrictions  on  the  amount  of  cash 
transfers  that  may  be  made  to  residents  of  foreign  countries  (subject  to  the  absence  of  any  specific 
decision taken by the government otherwise). Laws and regulations concerning foreign exchange controls 
do, however, require that all payments or transfers of funds made by a French resident to a non-resident 
such  as  dividend  payments  be  handled  by  an  accredited  intermediary.  All  registered  banks  and 
substantially  all  credit  institutions  in  France  are  accredited  intermediaries.  For  completeness,  there  is  a 
reporting obligation to the custom officer for transfer of cash in banknotes and coins of €10,000 or more 
carried into, or out of, the European Union.

Taxation. 

Material U.S. Federal Income Tax Considerations

The  following  describes  material  U.S.  federal  income  tax  considerations  relating  to  the  acquisition, 
ownership and disposition of the ordinary shares or ADSs by a U.S. holder (as defined below) who hold 
the ordinary shares or ADSs as capital assets. This summary does not address all U.S. federal income tax 
matters that may be relevant to a particular U.S. holder, such as the effects of Section 451(b) of the Code. 
This summary does not address tax considerations applicable to a holder of the ordinary shares or ADSs 
that may be subject to special tax rules including, without limitation, the following: 

•

•

•

•

•

•

•

•

•

•

•

banks, financial institutions or insurance companies; 

brokers, dealers or traders in securities, currencies, commodities, or notional principal contracts; 

tax-exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as 
defined in Section 408 or 408A of the Code (as defined below), respectively; 

real estate investment trusts, regulated investment companies or grantor trusts; 

persons that hold the ordinary shares or ADSs as part of a “hedging,” “integrated,” “wash sale” or 
“conversion” transaction or as a position in a “straddle” for U.S. federal income tax purposes; 

S  corporations,  partnerships,  or  other  entities  or  arrangements  classified  as  partnerships,  for  U.S. 
federal income tax purposes; 

certain former citizens or long-term residents of the United States; 

persons that received the ordinary shares or ADSs as compensation for the performance of services; 

persons  acquiring  the  ordinary  shares  or  ADSs  in  connection  with  a  trade  or  business  conducted 
outside of the United States, including a permanent establishment or a fixed base in France; 

holders  that  own  directly,  indirectly,  or  through  attribution  10%  or  more  of  the  voting  power  or 
value of the ordinary shares or ADSs; and 

holders that have a “functional currency” other than the U.S. dollar. 

Holders of the ordinary shares or ADSs who fall within one of the categories above are advised to consult 
their tax advisor regarding the specific tax consequences which may apply to their particular situation. 

For the purposes of this description, a “U.S. holder” is a beneficial owner of the ordinary shares or ADSs 
that is (or is treated as), for U.S. federal income tax purposes: 

•

an individual who is a citizen or resident of the United States; 

215

•

•

•

a corporation, or other entity taxable as a corporation, created or organized in or under the laws of 
the United States, any state therein or the District of Columbia; 

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or 

a  trust,  if  a  court  within  the  United  States  is  able  to  exercise  primary  supervision  over  its 
administration  and  one  or  more  U.S.  persons  have  the  authority  to  control  all  of  the  substantial 
decisions of such trust, or if such trust has a valid election in effect under applicable U.S. Treasury 
Regulations to be treated as a U.S. person. 

If a partnership (or any other entity or arrangement treated as a partnership for U.S. federal income tax 
purposes)  holds  the  ordinary  shares  or  ADSs,  the  tax  consequences  relating  to  an  investment  in  the 
ordinary  shares  or  ADSs  will  depend  in  part  upon  the  status  of  the  partner  and  the  activities  of  the 
partnership.  Such  a  partner  or  partnership  should  consult  its  tax  advisor  regarding  the  specific  tax 
considerations  of  acquiring,  owning  and  disposing  of  the  ordinary  shares  or  ADSs  in  its  particular 
circumstances. 

Persons  considering  an  investment  in  the  ordinary  shares  or  ADSs  should  consult  their  own  tax 
advisors  as  to  the  particular  tax  consequences  applicable  to  them  relating  to  the  acquisition, 
ownership  and  disposition  of  the  ordinary  shares  or  ADSs,  including  the  applicability  of  U.S. 
federal, state and local tax laws, French tax laws and other non-U.S. tax laws. 

This description does not address the U.S. federal estate, gift or alternative minimum tax considerations, 
the Medicare tax on net investment income or any U.S. state, local or non-U.S. tax considerations of the 
acquisition, ownership and disposition of the ordinary shares or ADSs. 

This description is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, existing, 
proposed  and  temporary  U.S.  Treasury  Regulations  promulgated  thereunder  and  administrative  and 
judicial interpretations thereof, in each case as of the date hereof. All the foregoing is subject to change, 
which change could apply retroactively, and to differing interpretations, all of which could affect the tax 
considerations described below. There can be no assurances that the U.S. Internal Revenue Service, or the 
IRS,  will  not  take  a  position  concerning  the  tax  consequences  of  the  acquisition,  ownership  and 
disposition of the ordinary shares or ADSs or that such a position would not be sustained by a court. The 
Company  has  not  obtained,  nor  does  the  Company  intend  to  obtain,  a  ruling  with  respect  to  the  U.S. 
federal  income  tax  considerations  of  the  purchase,  ownership  or  disposition  of  its  ordinary  shares  or 
ADSs. Accordingly, holders should consult their own tax advisors concerning the U.S. federal, state, local 
and  non-U.S.  tax  consequences  of  acquiring,  owning  and  disposing  of  the  ordinary  shares  or  ADSs  in 
their particular circumstances. 

As indicated below, this summary is subject to the discussion below of the U.S. federal income tax rules 
applicable to a “passive foreign investment company” (PFIC). 

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, a U.S. 
holder  holding  ADSs  will  be  treated  as  the  owner  of  the  ordinary  shares  represented  by  the  ADSs. 
Exchanges of ordinary shares for ADSs, and ADSs for ordinary shares, generally will not be subject to 
U.S. federal income tax. 

Distributions. Subject to the discussion under “—Passive Foreign Investment Company Considerations,” 
below,  the  gross  amount  of  any  distribution  (including  any  amounts  withheld  in  respect  of  foreign  tax) 
actually  or  constructively  received  by  a  U.S.  holder  with  respect  to  the  ordinary  shares  or  ADSs  will 
generally be taxable to the U.S. holder as a dividend to the extent of the U.S. holder’s pro rata share of the 
current  or  accumulated  earnings  and  profits  as  determined  under  U.S.  federal  income  tax  principles. 

216

Distributions  in  excess  of  earnings  and  profits  will  generally  be  non-taxable  to  the  U.S.  holder  to  the 
extent  of,  and  will  be  applied  against  and  reduce,  the  U.S.  holder’s  adjusted  tax  basis  in  the  ordinary 
shares or ADSs. Distributions in excess of earnings and profits and such adjusted tax basis will generally 
be taxable to the U.S. holder as either long-term or short-term capital gain depending upon whether the 
U.S. holder has held the ordinary shares or ADSs for more than one year as of the time such distribution 
is  received.  However,  since  the  Company  does  not  calculate  its  earnings  and  profits  under  U.S.  federal 
income  tax  principles,  it  is  expected  that  any  distribution  will  be  reported  as  a  dividend,  even  if  that 
distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules 
described  above.  Non-corporate  U.S.  holders  may  qualify  for  the  preferential  rates  of  taxation  with 
respect to dividends on the ordinary shares or ADSs applicable to long-term capital gains (i.e., gains from 
the sale of capital assets held for more than one year), or qualified dividend income if the Company is a 
“qualified  foreign  corporation”  and  certain  other  requirements  are  met.  A  non-U.S.  corporation  (other 
than  a  corporation  that  is  a  PFIC  for  the  taxable  year  in  which  the  dividend  is  paid  or  the  preceding 
taxable year) generally will be considered to be a qualified foreign corporation (a) if it is eligible for the 
benefits  of  a  comprehensive  tax  treaty  with  the  United  States  which  the  Secretary  of  Treasury  of  the 
United States determines is satisfactory for purposes of this provision and which includes an exchange of 
information provision, or (b) with respect to any dividend it pays on ADSs which are readily tradable on 
an established securities market in the United States. The ADSs are listed on the Nasdaq Global Select 
Market,  which  is  an  established  securities  market  in  the  United  States,  and  the  Company  believes  the 
ADSs are readily tradable on the Nasdaq Global Select Market. There can be no assurance that the ADSs 
will continue to be considered readily tradable on an established securities market in the United States in 
later years. The Company, which is incorporated under the laws of France, believes that it qualifies as a 
resident  of  France  for  purposes  of,  and  is  eligible  for  the  benefits  of,  the  Convention  between  the 
Government  of  the  United  States  of  America  and  the  Government  of  the  French  Republic  for  the 
Avoidance  of  Double  Taxation  and  the  Prevention  of  Fiscal  Evasion  with  Respect  to  Taxes  on  Income 
and  Capital,  signed  on  August  31,  1994,  as  amended  and  currently  in  force,  or  the  U.S.-France  Tax 
Treaty, although there can be no assurance in this regard. Further, the IRS has determined that the U.S.-
France  Tax  Treaty  is  satisfactory  for  purposes  of  the  qualified  dividend  rules  and  that  it  includes  an 
exchange-of-information  program.  Therefore,  subject  to  the  discussion  under  “—Passive  Foreign 
Investment  Company  Considerations,”  below,  such  dividends  will  generally  be  “qualified  dividend 
income” in the hands of individual U.S. holders, provided that a holding period requirement (more than 
60 days of ownership, without protection from the risk of loss, during the 121-day period beginning 60 
days  before  the  ex-dividend  date)  and  certain  other  requirements  are  met.  The  dividends  will  not  be 
eligible for the dividends-received deduction generally allowed to corporate U.S. holders. 

Subject  to  applicable  limitations  and  the  Final  FTC  Treasury  Regulations  (as  defined  below),  a  U.S. 
holder generally may claim the amount of any French withholding tax on a distribution not exceeding the 
rate provided by the U.S.-France Tax Treaty (as defined below) as either a deduction from gross income 
or  a  credit  against  its  U.S.  federal  income  tax  liability.  French  taxes  withheld  in  excess  of  the  rate 
applicable  with  respect  to  such  U.S.  holder  under  the  U.S.-France  Tax  Treaty  will  not  be  eligible  for  a 
credit against a U.S. holder’s federal income tax liability. Treasury Regulations issued on December 28, 
2021, which apply to foreign taxes paid or accrued in taxable years beginning on or after December 28, 
2021,  or  the  Final  FTC  Treasury  Regulations,  impose  additional  requirements  for  foreign  taxes  to  be 
eligible for credit.  However, the IRS has indicated that taxpayers may defer the application of many of 
the additional requirements until further notice. U.S. holders should consult their tax advisors regarding 
the  availability  of  foreign  tax  credits  for  any  amounts  withheld  with  respect  to  dividends  on  ADSs  or 
ordinary shares, including under the Final FTC Treasury Regulations. 

The foreign tax credit is subject to numerous complex limitations that must be determined and applied on 
an  individual  basis.  Generally,  the  credit  cannot  exceed  the  proportionate  share  of  a  U.S.  holder’s  U.S. 

217

federal income tax liability that such U.S. holder’s taxable income bears to such U.S. holder’s worldwide 
taxable income. In applying this limitation, dividends received generally will be treated as income from 
foreign  sources  and  generally  will  be  “passive  category  income,”  or  in  certain  cases  “general  category 
income” or “foreign branch income,” which is treated separately from other types of income for purposes 
of computing the foreign tax credit allowable to U.S. holders. In addition, the creditability of foreign taxes 
could  be  affected  by  actions  taken  by  intermediaries  in  the  chain  of  ownership  between  the  holders  of 
ADSs  or  ordinary  shares  and  the  Company  if,  as  a  result  of  such  actions,  the  holders  of  our  ADSs  or 
ordinary shares are not properly treated as beneficial owners of the underlying ordinary shares. Each U.S. 
holder should consult its own tax advisors regarding the foreign tax credit rules.

In general, the amount of a distribution paid to a U.S. holder in a foreign currency will be the U.S. dollar 
value of the foreign currency calculated by reference to the spot exchange rate on the day the depositary 
receives the distribution, in the case of the ADSs, or on the day the distribution is received by the U.S. 
holder, in the case of ordinary shares, regardless of whether the foreign currency is converted into U.S. 
dollars at that time. Any foreign currency gain or loss a U.S. holder realizes on a subsequent conversion 
of foreign currency into U.S. dollars will be U.S. source ordinary income or loss. If dividends received in 
a foreign currency are converted into U.S. dollars on the day they are received, a U.S. holder should not 
be required to recognize foreign currency gain or loss in respect of the dividend. 

Sale,  Exchange  or  Other  Taxable  Disposition.  A  U.S.  holder  will  generally  recognize  gain  or  loss  for 
U.S.  federal  income  tax  purposes  upon  the  sale,  exchange  or  other  taxable  disposition  of  the  ordinary 
shares  or  ADSs  in  an  amount  equal  to  the  difference  between  the  amount  realized  from  such  sale  or 
exchange and the U.S. holder’s adjusted tax basis in those ordinary shares or ADSs, each as determined in 
U.S.  dollars.  U.S.  holders  should  consult  their  own  tax  advisors  about  how  to  account  for  proceeds 
received on the sale, exchange or other taxable disposition of ordinary shares or ADSs that are not paid in 
U.S.  dollars.  Subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company  Considerations” 
below,  this  gain  or  loss  will  generally  be  a  capital  gain  or  loss.  The  adjusted  tax  basis  in  the  ordinary 
shares or ADSs generally will be equal to the U.S dollar cost of such ordinary shares or ADSs. Capital 
gain  from  the  sale,  exchange  or  other  taxable  disposition  of  the  ordinary  shares  or  ADSs  by  a  non-
corporate U.S. holder is generally eligible for a preferential rate of taxation applicable to capital gains, if 
the  non-corporate  U.S.  holder’s  holding  period  determined  at  the  time  of  such  sale,  exchange  or  other 
taxable  disposition  for  such  ordinary  shares  or  ADSs  exceeds  one  year  (i.e.,  such  gain  is  long-term 
taxable  gain).  The  deductibility  of  capital  losses  for  U.S.  federal  income  tax  purposes  is  subject  to 
limitations. Any such gain or loss that a U.S. holder recognizes generally will be treated as U.S. source 
gain or loss for foreign tax credit limitation purposes.  

Passive Foreign Investment Company Considerations. If the Company is a PFIC in any taxable year, a 
U.S. holder will be subject to special rules generally intended to reduce or eliminate any benefits from the 
deferral of U.S. federal income tax that a U.S. holder could derive from investing in a non-U.S. company 
that does not distribute all of its earnings on a current basis. 

The  Company  will  be  a  PFIC  for  U.S.  federal  income  tax  purposes  in  any  taxable  year  in  which,  after 
applying certain look-through rules with respect to the income and assets of its subsidiaries, either: (1) at 
least 75% of the gross income is “passive income” or (2) at least 50% of the average quarterly value of 
the total gross assets (which would generally be measured by fair market value of its assets, and for which 
purpose the total value of its assets may be determined in part by the market value of the ADSs and its 
ordinary shares, which are subject to change) is attributable to assets that produce “passive income” or are 
held for the production of “passive income.” 

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from 
commodities and securities transactions, the excess of gains over losses from the disposition of assets 

218

which produce passive income, and includes amounts derived by reason of the temporary investment of 
funds raised in offerings of the ordinary shares or ADSs. If a non-U.S. corporation owns directly or 
indirectly at least 25% by value of the stock of another corporation or entity treated as a partnership for 
U.S. federal income tax purposes, the non-U.S. corporation is treated for purposes of the PFIC tests as 
owning its proportionate share of the assets of such entity and as receiving directly its proportionate share 
of the other entity’s income. The determination of whether the Company is a PFIC is a fact-intensive 
determination made on an annual basis, and the applicable law is subject to varying interpretation. If the 
Company is a PFIC in any taxable year during which a U.S. holder owns its ordinary shares or ADSs, 
such U.S. holder will be subject to special tax rules discussed below and could suffer adverse tax 
consequences. 

The market value of the assets may be determined in large part by reference to the market price of the 
ADSs and its ordinary shares. Therefore, fluctuations in the market price of the ordinary shares or ADSs 
may result in the Company being a PFIC for any taxable year. Whether the Company is a PFIC for any 
taxable year will depend on income, assets, activities and market capitalization in each year, and because 
this is a factual determination made annually after the end of each taxable year, there can be no assurance 
that  the  Company  will  not  be  a  PFIC  in  any  taxable  year.  The  Company  does  not  believe  it  was 
characterized as a PFIC in its taxable year ended December 31, 2023. However, there can be no assurance 
that the Company will not be a PFIC in the current year or for any future taxable year. Its U.S. counsel 
expresses no opinion regarding its conclusions or its expectations regarding its PFIC status. 

If  the  Company  is  a  PFIC  in  any  year  with  respect  to  which  a  U.S.  holder  owns  its  ordinary  shares  or 
ADSs,  the  Company  will  continue  to  be  treated  as  a  PFIC  with  respect  to  such  U.S.  holder  in  all 
succeeding years during which the U.S. holder owns the ordinary shares or ADSs, regardless of whether 
the Company continue to meet the tests described above unless the Company ceases to be a PFIC and the 
U.S. holder has made a “deemed sale” election under the PFIC rules or is eligible to make and makes a 
mark-to-market election (as described below), with respect to all taxable years during such U.S. holder’s 
holding period in which the Company is a PFIC. If the “deemed sale” election is made, a U.S. holder will 
be deemed to have sold the ordinary shares or ADSs the U.S. holder holds at their fair market value as of 
the date of such deemed sale and any gain from such deemed sale would be subject to the rules described 
below. After the deemed sale election, so long as the Company does not become a PFIC in a subsequent 
taxable  year,  the  U.S.  holder’s  ordinary  shares  or  ADSs  with  respect  to  which  such  election  was  made 
will not be treated as shares in a PFIC and the U.S. holder will not be subject to the rules described below 
with respect to any “excess distribution” the U.S. holder receives from the Company or any gain from an 
actual  sale  or  other  disposition  of  the  ordinary  shares  or  ADSs.  U.S.  holders  should  consult  their  tax 
advisors as to the possibility and consequences of making a deemed sale election if such election becomes 
available. 

If the Company is a PFIC, and you are a U.S. holder that does not make one of the elections described 
above (and below in further detail), a special tax regime will apply to both (a) any “excess distribution” 
by the Company to you (generally, your ratable portion of distributions in any year which are greater than 
125%  of  the  average  annual  distribution  received  by  you  in  the  shorter  of  the  three  preceding  years  or 
your  holding  period  for  its  ordinary  shares  or  ADSs)  and  (b)  any  gain  realized  on  the  sale  or  other 
disposition of its ordinary shares or ADSs. Under this regime, any excess distribution and realized gain 
will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had 
been realized ratably over your holding period for the ordinary shares or ADSs, (b) the amount deemed 
realized in each year had been subject to tax in each year of that holding period at the highest marginal 
rate  for  such  year  (other  than  income  allocated  to  the  current  period  or  any  taxable  period  before  the 
Company became a PFIC, which would be subject to tax at the U.S. holder’s regular ordinary income rate 
for the current year and would not be subject to the interest charge discussed below), and (c) the interest 

219

charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been 
payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates 
of taxation applicable to qualified dividends discussed above under “Distributions.” 

Certain elections may alleviate some of the adverse consequences of PFIC status and would result in an 
alternative treatment of the ordinary shares or ADSs. If a U.S. holder makes a mark-to-market election, 
the  U.S.  holder  generally  will  recognize  as  ordinary  income  any  excess  of  the  fair  market  value  of  the 
ordinary shares or ADSs at the end of each taxable year over their adjusted tax basis, and will recognize 
an ordinary loss in respect of any excess of the adjusted tax basis of the ordinary shares or ADSs over 
their fair market value at the end of the taxable year (but only to the extent of the net amount of income 
previously included as a result of the mark-to-market election). If a U.S. holder makes the election, the 
U.S.  holder’s  tax  basis  in  the  ordinary  shares  or  ADSs  will  be  adjusted  to  reflect  these  income  or  loss 
amounts. Any gain recognized on the sale or other disposition of the ordinary shares or ADSs in a year in 
which  the  Company  is  a  PFIC  will  be  treated  as  ordinary  income  and  any  loss  will  be  treated  as  an 
ordinary loss (but only to the extent of the net amount of income previously included as a result of the 
mark-to-market election). The mark-to-market election is available only if the Company is a PFIC and its 
ordinary shares or ADSs are “regularly traded” on a “qualified exchange.” Its ordinary shares or ADSs 
will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of its 
ordinary  shares  or  ADSs  are  traded  on  a  qualified  exchange  on  at  least  15  days  during  each  calendar 
quarter  (subject  to  the  rule  that  trades  that  have  as  one  of  their  principal  purposes  the  meeting  of  the 
trading requirement are disregarded). The Nasdaq Global Select Market is a qualified exchange for this 
purpose and, consequently, if the ADSs are regularly traded, the mark-to-market election will be available 
to a U.S. holder. It should be noted that only the ADSs and not its ordinary shares are listed on the Nasdaq 
Global Select Market. Consequently, its ordinary shares may not be marketable if Euronext Paris (where 
its ordinary shares are listed) does not meet the applicable requirements. U.S. holders should consult their 
tax  advisors  regarding  the  availability  of  the  mark-to-market  election  for  ordinary  shares  that  are  not 
represented by ADSs. 

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs 
that the Company owns, unless shares of such lower-tier PFIC are themselves “marketable.” As a result, 
even if a U.S. holder validly makes a mark-to-market election with respect to its ordinary shares or ADSs, 
the U.S. holder may continue to be subject to the PFIC rules (described above) with respect to its indirect 
interest in any of its investments that are treated as an equity interest in a PFIC for U.S. federal income 
tax  purposes.  U.S.  holders  should  consult  their  tax  advisors  as  to  the  availability  and  desirability  of  a 
mark-to-market election, as well as the impact of such election on interests in any lower-tier PFICs. 

The Company does not currently intend to provide the information necessary for U.S. holders to make a 
“qualified electing fund election” if the Company is treated as a PFIC for any taxable year. U.S. holders 
should consult their tax advisors to determine whether this election would be available and if so, what the 
consequences of the alternative treatments would be in their particular circumstances. 

If the Company is a PFIC, the general tax treatment for U.S. holders described in this section would apply 
to  indirect  distributions  and  gains  deemed  to  be  realized  by  U.S.  holders  in  respect  of  any  of  its 
subsidiaries  that  also  may  be  PFICs.  U.S.  holders  should  consult  their  tax  advisors  regarding  the 
application of the PFIC rules to the Company's subsidiaries. 

If  a  U.S.  holder  owns  its  ordinary  shares  or  ADSs  during  any  taxable  year  in  which  the  Company  is  a 
PFIC,  the  U.S.  holder  generally  will  be  required  to  file  an  IRS  Form  8621  (Information  Return  by  a 
Shareholder  of  a  Passive  Foreign  Investment  Company  or  Qualified  Electing  Fund)  with  respect  to  the 
Company, generally with the U.S. holder’s federal income tax return for that year. If the Company is a 

220

PFIC  for  a  given  taxable  year,  then  you  should  consult  your  tax  advisor  concerning  your  annual  filing 
requirements. 

The  U.S.  federal  income  tax  rules  relating  to  PFICs  are  complex.  Prospective  U.S.  investors  are 
urged to consult their own tax advisors with respect to the acquisition, ownership and disposition of 
the ordinary shares or ADSs, the consequences to them of an investment in a PFIC, any elections 
available  with  respect  to  the  ordinary  shares  or  ADSs  and  the  IRS  information  reporting 
obligations  with  respect  to  the  acquisition,  ownership  and  disposition  of  the  ordinary  shares  or 
ADSs. 

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information 
reporting  requirements  with  respect  to  dividends  on  the  ordinary  shares  or  ADSs  and  on  the  proceeds 
from  the  sale,  exchange  or  disposition  of  the  ordinary  shares  or  ADSs  that  are  paid  within  the  United 
States or through U.S.-related financial intermediaries, unless the U.S. holder is an “exempt recipient.” In 
addition,  U.S.  holders  may  be  subject  to  backup  withholding  on  such  payments,  unless  the  U.S.  holder 
provides a taxpayer identification number and a duly executed IRS Form W-9 or otherwise establishes an 
exemption. Backup withholding is not an additional tax, and the amount of any backup withholding will 
be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and may entitle such holder 
to a refund, provided that the required information is timely furnished to the IRS. 

Foreign Asset Reporting. Certain individual U.S. holders are required to report information relating to an 
interest in the ordinary shares or ADSs, subject to certain exceptions (including an exception for shares 
held  in  accounts  maintained  by  U.S.  financial  institutions)  by  filing  IRS  Form  8938  (Statement  of 
Specified Foreign Financial Assets) with their federal income tax return. U.S. holders are urged to consult 
their tax advisors regarding their information reporting obligations, if any, with respect to their ownership 
and disposition of the ordinary shares or ADSs. 

THE  DISCUSSION  ABOVE  IS  A  SUMMARY  OF  THE  U.S.  FEDERAL  INCOME  TAX 
CONSEQUENCES  OF  AN  INVESTMENT  IN  THE  ORDINARY  SHARES  OR  ADSs  AND  IS 
BASED UPON LAWS AND RELEVANT INTERPRETATIONS THEREOF IN EFFECT AS OF 
THE  DATE  OF  THIS  ANNUAL  REPORT,  ALL  OF  WHICH  ARE  SUBJECT  TO  CHANGE, 
POSSIBLY  WITH  RETROACTIVE  EFFECT.  EACH  PROSPECTIVE  INVESTOR  IS  URGED 
TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN 
INVESTMENT  IN  THE  ORDINARY  SHARES  OR  ADSs  IN  LIGHT  OF  THE  INVESTOR’S 
OWN CIRCUMSTANCES.

Material French Tax Considerations 

The  following  describes  the  material  French  income  tax  consequences  to  U.S.  holders  of  purchasing, 
owning and disposing of ordinary shares or the ADSs. 

This  discussion  does  not  purport  to  be  a  complete  analysis  or  listing  of  all  potential  tax  effects  of  the 
acquisition, ownership or disposition of our ordinary shares or the ADSs to any particular investor, and 
does  not  discuss  tax  considerations  that  arise  from  rules  of  general  application  or  that  are  generally 
assumed to be known by investors. All of the following is subject to change. Such changes could apply 
retroactively and could affect the consequences described below. 

French tax rules applicable to French assets that are held by or in foreign trusts generally provide inter 
alia for the inclusion of trust assets in the settlor’s net assets for the purpose of applying the French real 
estate  wealth  tax  ,  for  the  application  of  French  gift  and  estate  tax  to  French  assets  held  in  trust,  for  a 
specific tax on capital on the French assets of foreign trusts not already subject to the French real estate 
wealth tax and for a number of French tax reporting and disclosure obligations. The following discussion 

221

does not address the French tax consequences applicable to securities (including ordinary shares or ADSs) 
held  in  trusts.  If  our  ordinary  shares  or  ADSs  are  held  in  trust,  the  grantor,  trustee  and  beneficiary  are 
advised to consult their own tax advisor regarding the specific tax consequences of acquiring, owning and 
disposing of such securities. 

The description of the French income tax and real estate wealth tax consequences set forth below is based 
on the double tax treaty entered into between the Government of the United States of America and the 
Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal 
Evasion  with  Respect  to  Taxes  on  Income  and  Capital  of  August  31,  1994  (the  “U.S.-France  Tax 
Treaty”),  which  came  into  force  on  December  30,  1995  (as  amended  by  any  subsequent  protocols, 
including the protocol of January 13, 2009), and the tax guidelines issued by the French tax authorities in 
force as of the date of this Annual Report. 

For the purposes of this discussion, the term “U.S. Holder” means a beneficial owner of securities that is 
(1)  an  individual  who  is  a  U.S.  citizen  or  resident  for  U.S.  federal  income  tax  purposes,  (2)  a  U.S. 
domestic  corporation  or  certain  other  entities  created  or  organized  in  or  under  the  laws  of  the  United 
States or any state thereof, or (3) otherwise subject to U.S. federal income taxation on a net income basis 
in respect of securities. 

If  a  partnership  holds  ADSs,  the  tax  treatment  of  the  partnership  and  a  partner  in  such  partnership 
generally  will  depend  on  the  status  of  the  partner  and  the  activities  of  the  partnership.  Such  partner  or 
partnership is urged to consult its own tax advisor regarding the specific tax consequences of acquiring, 
owning and disposing of ADSs. 

This  discussion  applies  only  to  investors  that  hold  ADSs  as  capital  assets  that  are  entitled  to  Treaty 
benefits under the “Limitation on Benefits” provision contained in the U.S.-France Tax Treaty, and whose 
ownership of the ordinary shares or ADSs is not effectively connected to a permanent establishment or a 
fixed base in France. Certain U.S. Holders (including, but not limited to, U.S. expatriates, partnerships or 
other entities classified as partnerships for U.S. federal income tax purposes, banks, insurance companies, 
regulated  investment  companies,  tax-exempt  organizations,  financial  institutions,  persons  subject  to  the 
alternative minimum tax, persons who acquired the securities pursuant to the exercise of employee share 
options or otherwise as compensation, persons that own (directly, indirectly or by attribution) 5% or more 
of  our  voting  stock  or  5%  or  more  of  our  outstanding  share  capital,  dealers  in  securities  or  currencies, 
brokers, mutual funds, individual retirement or other tax-deferred accounts persons that elect to mark their 
securities to market for U.S. federal income tax purposes and persons holding securities as a position in a 
synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below, 
and  are  advised  to  consult  their  usual  tax  advisor  regarding  the  specific  tax  consequences  which  may 
apply to their particular situation. 

U.S. Holders are advised to consult their own tax advisor regarding the tax consequences of the purchase, 
ownership and disposition of securities in light of their particular circumstances, especially with regard to 
the “Limitations on Benefits” provision contained in the U.S.-France Tax Treaty. 

Tax on Sale or other Disposals 

As a matter of principles, under French tax law subject to limited exemptions,and to the extent Innate is 
not a real estate company for the purpose of Article 244 bis A of the French Tax Code (Code général des 
impôts, the “FTC”), a U.S. Holder should not be subject to any French tax on any capital gain from the 
sale,  exchange,  repurchase  or  redemption  by  Innate  of  ordinary  shares  or  ADSs,  provided  such  U.S. 
Holder  is  not  a  French  tax  resident  for  French  tax  purposes  and  has  not  held  more  than  25%  of  the 
dividend  rights,  known  as  “droits  aux  bénéfices  sociaux,”  at  any  time  during  the  preceding  five  years, 
either  directly  or  indirectly,  and,  as  relates  to  individuals,  alone  or  with  relatives  it  has  not  transferred 

222

ordinary shares or ADSs as part of redemption by Innate, in which case the proceeds may under certain 
circumstances be partially or fully characterized as dividends under French domestic law and, as result, be 
subject to French dividend withholding tax.

As an exception, a U.S. Holder resident, established or incorporated in certain non-cooperative States or 
territories as defined in Article 238-0 A of the FTC should be subject to a 75% withholding tax in France 
on any such capital gain, regardless of the fraction of the dividend rights it holds, subject to safe-harbor 
provisions and the more favorable provisions of the U.S.-France Tax Treaty. The list of non-cooperative 
State or territory is published by decree and is in principle updated annually. This list was last updated on 
16  February  2024,  and  currently  includes  American  Samoa,  Anguilla,  Antigua  and  Barbuda,  the 
Bahamas,  Belize,  Fiji,  Guam,  Palaos,  Panama,  Russia,  Samoa,  Seychelles,  Trinidad  and  Tobago,  Turk 
and Caicos, the United States Virgin Islands and Vanuatu. States referred to in Article 238-0 A, 2 bis-2° 
of the FTC, and thus outside of the scope of Article 244 bis B of the FTC, are currently American Samoa, 
Fiji, Guam, Palaos, Samoa, Trinidad and Tobago and the United States Virgin Islands. 

Under application of the U.S.-France Tax Treaty, a U.S. Holder who is a U.S. resident for purposes of the 
U.S.-France Tax Treaty and entitled to Treaty benefits will not be subject to French tax on such capital 
gain  unless  the  ordinary  shares  or  the  ADSs  form  part  of  the  business  property  of  a  permanent 
establishment or fixed base that the U.S. Holder has in France. U.S. Holders who own ordinary shares or 
ADSs through U.S. partnerships that are not resident for U.S.-France Tax Treaty purposes are advised to 
consult their own tax advisor regarding their French tax treatment and their eligibility for Treaty benefits 
in light of their own particular circumstances.

A U.S. Holder that is not a U.S. resident for U.S.-France Tax Treaty purposes or is not entitled to Treaty 
benefits (and in both cases is not resident, established or incorporated in certain non-cooperative States or 
territories as defined in Article 238-0 A of the FTC) and has held more than 25% of the dividend rights, 
known  as  “droits  aux  bénéfices  sociaux”  at  any  time  during  the  preceding  five  years,  either  directly  or 
indirectly, and, as relates to individuals, alone or with relatives will be subject to a levy in France (i) at the 
rate of 12.8% for individuals, and (ii) 25% for legal persons. However, eligible non-French tax resident 
legal entities may claim a refund of the 25% French levy to the extent such tax exceeds the amount that 
would  have  been  due  under  French  corporate  income  tax  if  they  had  been  French  tax  residents.  This 
refund  mechanism  is  only  available  to  certain  legal  entities.  Non-French  tax  resident  legal  entities  are 
advised to consult their own tax adviser regarding their French tax treatment and their eligibility to this 
refund mechanism.

The above French provisions expressly apply to sale, repurchase or redemption by us of ordinary shares. 

Special rules apply to U.S. Holders who are residents of more than one country.

Financial Transactions Tax 

Pursuant to Article 235 ter ZD of the FTC, purchases of shares or ADSs of a French company listed on a 
regulated market of the European Union or on a foreign regulated market formally acknowledged by the 
AMF  are  subject  to  a  0.3%  French  tax  on  financial  transactions  provided  that  the  issuer’s  market 
capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year. A list of 
companies whose market capitalization exceeds 1 billion euros as of December 1 of the year preceding 
the  taxation  year,  within  the  meaning  of  Article  235  ter  ZD  of  the  FTC,  is  published  annually  by  the 
French tax authorities in their official guidelines. As at December 1, 2023, the market capitalization did 
not exceed 1 billion euros, pursuant to BOI-ANNX-000467-20/12/2023 issued on December 20, 2023.

Moreover, Nasdaq Global Select Market, on which ADSs are listed, is not currently acknowledged by the 
AMF, but this may change in the future. 

223

As a consequence, neither the ADSs nor the ordinary shares are currently within the scope of the French 
tax on financial transactions. 

Purchases of our securities may be subject to such tax in the future provided that the market capitalization 
exceeds 1 billion euros in the year preceding the taxation year and that the Nasdaq Global Select Market 
is acknowledged by the French AMF. 

Registration Duties

In the case where Article 235 ter ZD of the FTC is not applicable, transfers of shares issued by a French 
company which are listed on a regulated or organized market within the meaning of the French monetary 
and financial code ("Code monétaire et financier") are subject to uncapped registration duties at the rate 
of 0.1% if the transfer is evidenced by a written statement (“acte”) executed either in France or outside 
France.  As  ordinary  shares  of  the  company  are  listed  on  Euronext  Paris,  which  is  an  organized  market 
within the meaning of the French monetary code, their transfer should be subject to uncapped registration 
duties at the rate of 0.1% subject to the existence of a written statement (“acte”), and provided that Article 
235 ter ZD of the FTC is not applicable. Although there is no case law or official guidelines published by 
the  French  tax  authorities  on  this  point,  transfer  of  ADSs  should  remain  outside  of  the  scope  of  the 
aforementioned  0.1%  registration  duties.  U.S.  Holders  are  urged  to  consult  their  own  tax  advisor  about 
the possible application of the registration duty upon the transfer of ADSs. 

Taxation of Dividends 

Dividends  paid  by  a  French  corporation  to  non-residents  of  France  are  generally  subject  to  French 
withholding  tax  at  a  rate  of  (i)  25%  for  payment  benefiting  legal  persons  which  are  not  French  tax 
residents, and (ii) 12.8% for payment benefiting individuals who are not French tax residents. Dividends 
paid by a French corporation in certain non-cooperative States or territories, as defined in Article 238-0 A 
of the FTC, will generally be subject to French withholding tax at a rate of 75%. However, eligible U.S. 
Holders  entitled  to  Treaty  benefits  under  the  “Limitation  on  Benefits”  provision  contained  in  the  U.S.-
France Tax Treaty who are U.S. residents, as defined pursuant to the provisions of the U.S.-France Tax 
Treaty, will not be subject to this 25% or 75% withholding tax rate, but may be subject to the withholding 
tax at a reduced rate (as described below). 

Under  the  U.S.-France  Tax  Treaty,  the  rate  of  French  withholding  tax  on  dividends  paid  to  an  eligible 
U.S. Holder who is a U.S. resident as defined pursuant to the provisions of the U.S.-France Tax Treaty 
and  whose  ownership  of  the  ordinary  shares  or  ADSs  is  not  effectively  connected  with  a  permanent 
establishment or fixed base that such U.S. Holder has in France, is generally reduced to 15%, or to 5% if 
such U.S. Holder is a corporation and owns directly or indirectly at least 10% of the share capital of the 
issuer; such U.S. Holder may claim a refund from the French tax authorities of the amount withheld in 
excess of the U.S.-France Tax Treaty rates of 15% or 5%, if any. 

For U.S. Holders that are not individuals but are U.S. residents, as defined pursuant to the provisions of 
the U.S.-France Tax Treaty, the requirements for eligibility for Treaty benefits, including the reduced 5% 
or 15% withholding tax rates contained in the “Limitation on Benefits” provision of the U.S.-France Tax 
Treaty, are complex, and certain technical changes were made to these requirements by the protocol of 
January 13, 2009. U.S. Holders are advised to consult their own tax advisor regarding their eligibility for 
Treaty benefits in light of their own particular circumstances. 

Dividends paid to an eligible U.S. Holder may immediately be subject to the reduced rates of 5% or 15% 
provided that: 

•

such holder establishes before the date of payment that it is a U.S. resident under the U.S.-France 
Tax  Treaty  by  completing  and  providing  the  depositary  with  a  treaty  form  (Form  5000)  in 

224

accordance  with  French  guidelines  (BOI-INT-DG-20-20-20-20-12/09/2012  dated  September  12, 
2012); or 

•

the  depositary  or  other  financial  institution  managing  the  securities  account  in  the  U.S.  of  such 
holder provides the French paying agent with a document listing certain information about the U.S. 
Holder and its ordinary shares or ADSs and a certificate whereby the financial institution managing 
the U.S. Holder’s securities account in the United States takes full responsibility for the accuracy of 
the information provided in the document. 

Otherwise,  dividends  paid  to  a  U.S.  Holder,  if  such  U.S.  Holder  is  a  legal  person,  will  be  subject  to 
French withholding tax at the rate of 25%, or 75% if paid in certain non-cooperative States or territories 
(as defined in Article 238-0 A of the FTC), and then reduced at a later date to 5% or 15%, provided that 
such holder duly completes and provides the French tax authorities with the treaty forms Form 5000 and 
Form 5001 (due to recent case law regarding status of limitation for filing a withholding tax claim; U.S. 
Holders are advised to consult their own tax advisors in this respect). 

Certain qualifying pension funds and certain other tax-exempt entities and certain U.S. residents may be 
subject to specific  filing requirements. They are advised to consult their own tax advisors on this point.

Form  5000  and  Form  5001,  together  with  instructions,  will  be  provided  by  the  depositary  to  all  U.S. 
Holders  registered  with  the  depositary.  The  depositary  will  arrange  for  the  filing  with  the  French  tax 
authorities  of  all  such  forms  properly  completed  and  executed  by  U.S.  Holders  of  ordinary  shares  or 
ADSs  and  returned  to  the  depositary  in  sufficient  time  so  that  they  may  be  filed  with  the  French  tax 
authorities  before  the  distribution  in  order  to  immediately  obtain  a  reduced  withholding  tax  rate. 
Otherwise, the depositary must withhold tax at the full rate of 25% or 75% as applicable. In that case, the 
U.S. Holders may claim a refund from the French tax authorities of the excess withholding tax. 

In any case, individual taxpayers who are not fiscally domiciled in France should not have to comply with 
these procedures if the French withholding tax applying to them is lower than 15%. 

In particular, since the withholding tax rate applicable under French domestic law to U.S. Holders who 
are individuals does not exceed the cap provided in the U.S.-France Tax Treaty (i.e., 15%), the 12.8% rate 
shall  apply,  without  any  reduction  provided  under  the  U.S.-France  Tax  Treaty  (except  in  the  particular 
situation  when the dividends are paid to such U.S. Holders out of France in a non-cooperative State or 
territory as defined in Article 238-0 A of the FTC other than those mentioned in 2° of 2 bis of the same 
Article 238-0 A of the FTC and are subject to the 75% withholding tax in France). 

Besides, please note that pursuant to Article 235 quater of the FTC (introduced by the French finance bill 
No.  2019-1479  for  2020)  and  under  certain  conditions  (in  particular,  in  addition  to  certain  reporting 
obligations,  the  interest  held  in  the  distributing  company  must  not  enable  the  beneficiary  to  participate 
effectively  in  the  management  or  control  of  that  company  and  the  beneficiary  company  is  located  in  a 
country  that  has  signed  an  administrative  assistance  agreement  with  France  to  combat  tax  evasion  and 
avoidance,  as  well  as  an  administrative  assistance  agreement  on  tax  collection,  and  that  is  not  a  non-
cooperative country), a corporate U.S. Holder which is in a tax loss position or which tax result is nil due 
to offset of tax losses (French Administrative Supreme Court, October 18, 2022, n° 466329) for the fiscal 
year during which the dividend is received may be entitled to a deferral regime, and obtain a withholding 
tax refund. The tax deferral ends in respect of the first financial year during which this U.S. Holder is in a 
profit making position, as well as in the cases set out in Article 235 quater of the FTC. The refund must 
be  claimed  within  the  same  period  applicable  to  claim  related  to  taxes  other  than  local  taxes.  Also, 
pursuant to Article 235 quinquies of the FTC and under certain conditions, a corporate U.S. Holder may 
be entitled to a refund of a fraction of the withholding tax, up to the difference between the withholding 
tax paid (on a gross basis) and the withholding tax based on the dividend net of the expenses incurred for 

225

the  acquisition  and  conservation  directly  related  to  the  income,  provided  (i)  that  these  expenses  would 
have been tax deductible had the U.S. Holder been established in France, and (ii) that the tax rules in the 
United States do not allow the U.S. Holder to offset the withholding tax.

Estate and Gift Taxes 

In general, a transfer of securities by gift or by reason of death of a U.S. Holder that would otherwise be 
subject to French gift or inheritance tax, respectively, will not be subject to such French tax by reason of 
the  double  tax  treaty  entered  into  between  the  Government  of  the  United  States  of  America  and  the 
Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal 
Evasion with Respect to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978 (as amended 
from time to time), unless (i) the donor or the transferor is domiciled in France at the time of making the 
gift or at the time of his or her death, or (ii) the securities were used in, or held for use in, the conduct of a 
business through a permanent establishment or a fixed base in France. 

Real Estate Wealth Tax 

As  from  January  1,  2018,  the  French  wealth  tax  (impôt  de  solidarité  sur  la  fortune)  is  repealed  and 
replaced by the French real estate wealth tax (impôt sur la fortune immobilière or IFI). The scope of such 
new  tax  is  narrowed  to  French  real  estate  assets  (and  certain  assets  deemed  to  be  real  estate  assets)  or 
rights, held directly or indirectly through one or more legal entities and whose net taxable assets amount 
at least to €1,300,000. 

Broadly,  subject  to  provisions  of  double  tax  treaties  and  to  certain  exceptions,  individuals  who  are  not 
residents of France for tax purposes within the meaning of Article 4 B of the FTC are subject to the IFI in 
France in respect of the portion of the value of their shares of the company representing real estate assets 
(Article 965, 2° of the FTC). Some exceptions are provided by the FTC. In particular, Innate’s ordinary 
shares or  ADSs owned by  a U.S. Holder should not fall within the scope of the IFI provided that such 
U.S.  Holder  does  not  own  (together  with  the  members  of  his/her  household)  directly  or  indirectly  a 
shareholding  exceeding  10%  of  the  financial  rights  and  voting  rights  of  Innate.  U.S.  Holders  holding 
directly  or  indirectly  a  shareholding  exceeding  10%  of  the  financial  rights  and  voting  rights  of  Innate 
should seek additional advice.

Under the U.S.-France Tax Treaty (the provisions of which should be applicable to this IFI in France), the 
IFI will however generally not apply to securities held by an eligible U.S. Holder who is a U.S. resident, 
as defined pursuant to the provisions of the U.S.-France Tax Treaty, provided that such U.S. Holder (i) 
does not own directly or indirectly more than 25% of the issuer’s financial rights and (ii) that the ADSs 
do not form part of the business property of a permanent establishment or fixed base in France. 

U.S. Holders are advised to consult their own tax advisor regarding the specific tax consequences which 
may apply to their particular situation with respect to such IFI.

Item 11. Quantitative and Qualitative Disclosures About Market Risk. 

The Company's activities are exposed to liquidity risk, foreign currency exchange risk, interest rate risk 
and credit risk. 

Liquidity risk 

The Company does not believe that it is exposed to short-term liquidity risk, considering its cash and cash 
equivalents  and  short-term  investments  of  €92.5  million  as  of  December  31,  2023,  which  consist 
primarily  of  cash  and  money  market  funds  and  term  deposits,  are  convertible  into  cash  immediately 
without penalty. 

Foreign currency exchange rate risk 

The Company is exposed to foreign exchange risk inherent in certain subcontracting activities related to 
its operations in the United States, which are invoiced in U.S. dollars. The Company does not currently 
have  material  recurring  revenues  in  euro,  dollars  or  in  any  other  currency.  As  the  Company  further 
increases its business, particularly in the United States, the Company expects to face greater exposure to 
exchange rate risk. 

Innate's  revenue  denominated  in  U.S.  dollars  has  represented  approximately  78%,  92%  and  29%  of 
revenue  in  the  years  ended  December  31,  2021,  2022  and  2023,  respectively.  Payments  in  U.S.  dollars 
represented approximately 50%, 50%, and 43% of the payments in the years ended December 31, 2021, 

227

2022 and 2023, respectively. In order to cover this foreign currency exchange rate risk, the Company kept 
in  U.S.  dollars  a  part  of  the  consideration  received  from  AstraZeneca  in  June  2015,  January  2019  and 
September  2020.  The  Company  kept  the  entire  U.S  dollars  portion  of  the  proceeds  received  from  its 
October 2019 global offering in U.S dollars. The Company does not use hedging instruments in its current 
operations. Refer to Item 3.D. Risk Factors - Innate's business may be exposed to foreign exchange risks. 

Interest rate risk 

The Company has limited exposure to interest rate risk. Its exposure primarily relates to money market 
funds and time deposit accounts. Changes in interest rates have a direct impact on the rate of return on 
these investments and the cash flows generated. The Company does not have any credit facilities bearing 
variable  interest  rates.  The  repayment  of  the  advances  from  BPI  France,  the  borrowings  subscribed  in 
2017  and  the  two  State  Guaranteed  Loans  obtained  in  2021  and  extended  in  2022,  are  not  subject  to 
interest rate risk. The effect of an increase or decrease in interest rates would have an immaterial effect on 
profit or loss. 

Credit risk 

The credit risk related to the cash equivalents, short-term investments and non-current financial assets is 
not  significant  in  light  of  the  quality  of  the  issuers.  The  Company  deemed  that  no  instrument  of  its 
portfolio is exposed to credit risk.

D. American Depositary Shares.

Citibank,  N.A.  ("Citibank")  acts  as  the  depositary  bank  for  the  ADSs.  Citibank’s  depositary  offices  are 
located  at  388  Greenwich  Street,  New  York,  New  York  10013.  ADSs  represent  ownership  interests  in 
securities that are on deposit with the depositary bank. ADSs may be represented by certificates that are 
commonly known as American Depositary Receipts (ADRs). Each ADS represents one ordinary share (or 
the right to receive one ordinary share). The depositary bank typically appoints a custodian to safekeep 
the securities on deposit. In this case, the custodian is Citibank Europe plc, 1 North Wall Quay, Dublin 1, 
Ireland. 

The Company has appointed Citibank, N.A. as depositary bank pursuant to a deposit agreement. A copy 
of the deposit agreement has been filed with the SEC under cover of a Registration Statement on Form 
F-6  (Registration  No.  333-234063).  You  may  obtain  a  copy  of  the  deposit  agreement  from  the  SEC’s 
website at www.sec.gov. 

For additional information on our ADSs, please refer to Exhibit 2.3 “Description of Securities Other than 
Equity Securities – American Depositary Shares” of this Annual Report.

the  share  register  and  applicable  to  transfers  of  ordinary  shares  to  or  from  the  name  of  the 

230

custodian,  the  depositary  bank  or  any  nominees  upon  the  making  of  deposits  and  withdrawals, 
respectively; 

certain cable, telex and facsimile transmission and delivery expenses; 

the fees, expenses, spreads, taxes and other charges of the depositary bank and/or service providers

with compliance with exchange control regulations and other regulatory requirements applicable to

•

•

•

•

ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the 
person for whom the ADSs are issued (in the case of ADS issuances) and to the person for whom ADSs 
are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary bank into 
DTC,  the  ADS  issuance  and  cancellation  fees  and  charges  may  be  deducted  from  distributions  made 
through DTC, and may be charged to the DTC participant(s) receiving the ADSs being issued or the DTC 
participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial owner(s) 
and  will  be  charged  by  the  DTC  participant(s)  to  the  account  of  the  applicable  beneficial  owner(s)  in 
accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees 
and  charges  in  respect  of  distributions  and  the  ADS  service  fee  are  charged  to  the  holders  as  of  the 
applicable ADS record date. In the case of distributions of cash, the amount of the applicable ADS fees 
and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash 
and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of the 
ADS  fees  and  charges  and  such  ADS  fees  and  charges  may  be  deducted  from  distributions  made  to 
holders  of  ADSs.  For  ADSs  held  through  DTC,  the  ADS  fees  and  charges  for  distributions  other  than 
cash  and  the  ADS  service  fee  may  be  deducted  from  distributions  made  through  DTC,  and  may  be 
charged to the DTC participants in accordance with the procedures and practices prescribed by DTC and 
the DTC participants in turn charge the amount of such ADS fees and charges to the beneficial owners for 
whom  they  hold  ADSs.  In  the  case  of  (i)  registration  of  ADS  transfers,  the  ADS  transfer  fee  will  be 
payable by the ADS Holder whose ADSs are being transferred or by the person to whom the ADSs are 
transferred, and (ii) conversion of ADSs of one series for ADSs of another series, the ADS conversion fee 
will be payable by the Holder whose ADSs are converted or by the person to whom the converted ADSs 
are delivered. 

In the event of refusal to pay the depositary bank fees, the depositary bank may, under the terms of the 
deposit agreement, refuse the requested service until payment is received or may set off the amount of the 
depositary bank fees from any distribution to be made to the ADS holder. Note that the fees and charges 
you  may  be  required  to  pay  may  vary  over  time  and  may  be  changed  by  Innate  and  by  the  depositary 
bank.  You  will  receive  prior  notice  of  such  changes.  The  depositary  bank  may  reimburse  Innate  for 
certain  expenses  incurred  by  Innate  Pharma  in  respect  of  the  ADR  program,  by  making  available  a 
portion  of  the  ADS  fees  charged  in  respect  of  the  ADR  program  or  otherwise,  upon  such  terms  and 
conditions as the Company and the depositary bank agree from time to time.

Payment of Taxes

ADS holders are responsible for the taxes and other governmental charges payable on the ADSs and the 
securities  represented  by  the  ADSs.  We,  the  depositary  bank  and  the  custodian  may  deduct  from  any 

231

distribution the taxes and governmental charges payable by holders and may sell any and all property on 
deposit to pay the taxes and governmental charges payable by holders. You are liable for any deficiency if 
the sale proceeds do not cover the taxes that are due. 

The depositary bank may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release 
securities on deposit until all taxes and charges are paid by the applicable holder. The depositary bank and 
the  custodian  may  take  reasonable  administrative  actions  to  obtain  tax  refunds  and  reduced  tax 
withholding  for  any  distributions  on  your  behalf.  However,  you  may  be  required  to  provide  to  the 
depositary bank and to the custodian proof of taxpayer status and residence and such other information as 
the  depositary  bank  and  the  custodian  may  require  to  fulfill  legal  obligations.  You  are  required  to 
indemnify us, the depositary bank and the custodian for any claims with respect to taxes based on any tax 
benefit obtained for you.

Item 15. Controls and Procedures. 

Disclosure Controls and Procedures

The management, with the participation of the Chief Executive Officer (principal executive officer) and 
the Chief Financial Officer (principal financial officer), after evaluating the effectiveness of the disclosure 
controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)), as of December 31, 
2023,  have  concluded  that,  the  disclosure  controls  and  procedures  were  effective  as  of  December  31, 
2023. 

Management’s Annual Report on Internal Control over Financial Reporting 

The management is responsible for establishing and maintaining adequate internal controls over financial 
reporting, as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f) for the assessment of the 
effectiveness of our internal control over financial reporting. Because of its inherent limitations, internal 
control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 

Under  the  supervision  and  with  the  participation  of  the  Chief  Executive  Officer  (principal  executive 
officer)  and  the  Chief  Financial  Officer  (principal  financial  officer),  the  management  conducted  an 
evaluation  of  internal  control  over  financial  reporting  based  upon  the  criteria  established  in  internal 
Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission (COSO). 

Based on that evaluation under these criteria, the management concluded that, as of December 31, 2023, 
the  Company's  internal  control  over  financial  reporting  was  effective  to  provide  reasonable  assurance 

232

regarding  the  reliability  of  its  financial  reporting  and  the  preparation  of  its  financial  statements  for 
external purposes, in accordance with International Financial Reporting Standards (IFRS) principles.

Due  to  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect 
misstatements, and can only provide reasonable assurance regarding the reliability of financial reporting 
and the preparation of financial statements. Also, projections of any evaluation of effectiveness to future 
periods are subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate. 

Remediation  of  Previously  Identified  Material  Weakness  in  Internal  Control  over  Financial 
Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial 
reporting,  such  that  there  is  a  reasonable  possibility  that  a  material  misstatement  of  the  financial 
statements will not be prevented or detected on a timely basis.

As previously disclosed in “Item 15 - Controls and Procedures” of our Annual Report on Form 20-F for 
the  year  ended  December  31,  2022,  management  concluded  that,  as  of  December  31,  2022,  the 
Company’s  internal  control  over  financial  reporting  was  not  effective  because  of  the  existence  of  a 
material weakness in the internal control over financial reporting in connection with the preparation of the 
financial results for the year ended December 31, 2022.

The material weakness in the aggregate was related to:

•

•

The control activities that allow detecting or preventing material errors in the classification and 
presentation of the consolidated financial statements, and related disclosure; and

The  control  activities  that  allow  ensuring  all  third-party  services  are  accounted  in  the  correct 
period.

In response to the identified material weakness, the Company took several actions during the year ended 
December 31, 2023, to enhance the design of its control activities, applying more granularity to avoid any 
material  errors  in  the  presentation  of  the  consolidated  financial  statements,  related  disclosures,  and  in 
relation to cutoff, including the following:

•

•

•

Implementation of an automated control in its Enterprise Resource Planning (ERP) tool requiring 
an  approval  by  the  Financial  Planning  and  Analysis  department  (FP&A)  of  allocation  of  a 
purchase order, including to appropriately classify expenses between General & Administration 
and Research & Development expenses;

Strengthening  of  the  reconciliation  of  the  data  collected  from  the  Company’s  alliance  partners 
with the consolidated financial statements and related disclosure to ensure a proper classification 
of the maturity of debts between current and non-current in the balance sheet; and

Improvement  of  existing  controls  to  include  a  verification  of  open  purchase  orders  without  any 
receipts or partially received so that third-party services are recorded in the correct period.

As  a  result  of  the  remediation  activities  described  above,  as  of  December  31,  2023,  management  has 
concluded that there is no material weakness in connection with the preparation of the financial results for 
the year ended December 31, 2023. Although we have determined that the previously identified material 
weaknesses  have  been  remediated  as  of  December  31,  2023,  we  cannot  assure  you  that  we  will  not 
identify  other  material  weaknesses  or  deficiencies,  which  could  negatively  impact  our  results  of 
operations in future periods.

Changes in Internal Control over Financial Reporting 

Other than the remediation activities described above, there were no changes in the internal control over 
financial reporting during the year ended December 31, 2023 that have materially affected, or are 
reasonably likely to materially affect, the internal control over financial reporting.

Item 16. Reserved.

Not applicable.

Item 16A. Audit Committees Financial Expert.

Innate's Supervisory Board has determined that Pascale Boissel is an "audit committee financial expert" 
as  defined  by  SEC  rules  and  regulations  and  each  of  the  members  of  the  Audit  Committee  has  the 
requisite financial sophistication under the applicable rules and regulations of the Nasdaq Stock Market. 
Ms. Boissel,  Dr. Staatz-Granzer and Dr. Sally Bennett are independent as such term is defined in Rule 
10A-3 under the Exchange Act and under the listing standards of the Nasdaq Stock Market.

Item 16B. Code of Business Conduct and Ethics.

The  Company  has  adopted  a  Code  of  Business  Conduct  and  Ethics,  or  the  Code  of  Ethics,  that  is 
applicable  to  all  of  its  employees,  executive  officers  and  directors.  A  copy  of  the  Code  of  Ethics  is 
available  on  its  website  at  www.investors.innate-pharma.com.  The  Audit  Committee  of  its  Supervisory 
board  is  responsible  for  overseeing  the  Code  of  Ethics  and  must  approve  any  waivers  of  the  Code  of 
Ethics for employees, executive officers and directors. The Company expects that any amendments to the 
Code of Ethics, or any waivers of its requirements, will be disclosed on its website.

Item 16C. Principal Accountant Fees and Services. 

Deloitte & Associés has served as the independent registered public accounting firm for 2022 and 2023. 
The accountants billed the following fees to Innate for professional services in each of those fiscal years, 
all of which were approved by the Audit Committee:

“Audit fees” are the aggregate fees billed for the audit of the annual financial statements. This category 
also includes services that Deloitte & Associés provides, such as consents and assistance with and review 
of documents filed with the SEC.

“Non-audit fees” are the aggregate fees billed for services related to the production of certification in the 
context  of  the  declaration  of  expenses  for  the  obtention  of  grants  and  the  preparation  of  special  reports

Audit and Non-Audit Services Pre-Approval Policy 

The Audit Committee has responsibility for appointing, setting compensation of and overseeing the work 
of  the  independent  registered  public  accounting  firm.  In  recognition  of  this  responsibility,  the  Audit 
Committee has adopted a policy governing the pre-approval of all audit and permitted non-audit services 
performed  by  the  independent  registered  public  accounting  firm  to  ensure  that  the  provision  of  such 
services  does  not  impair  the  independent  registered  public  accounting  firm’s  independence  from  Innate 
and  the  management.  Unless  a  type  of  service  to  be  provided  by  the  independent  registered  public 
accounting  firm  has  received  general  pre-approval  from  the  Audit  Committee,  it  requires  specific  pre-
approval by the Audit Committee. The payment for any proposed services in excess of pre-approved cost 
levels requires specific pre-approval by the Audit Committee.

Pursuant  to  its  pre-approval  policy,  the  Audit  Committee  may  delegate  its  authority  to  pre-approve 
services  to  the  chairperson  of  the  Audit  Committee.  The  decisions  of  the  chairperson  to  grant  pre-
approvals  must  be  presented  to  the  full  Audit  Committee  at  its  next  scheduled  meeting.  The  Audit 
Committee may not delegate its responsibilities to pre-approve services to the management.

The Audit Committee has considered the non-audit services provided by Deloitte & Associés as described 
above and believes that they are compatible with maintaining Deloitte & Associés’s independence as the 
independent registered public accounting firm.

The  term  of  office  of  Odycé  Nexia  SAS,  joint  principal  Statutory  Auditor  of  the  Company,  will  expire 
following the general meeting of shareholders of May 23, 2024. The Shareholders' Meeting will be called 
upon to decide on the appointment of PriceWaterhouseCoopers Audit as new Statutory Auditor to replace 
Odycé Nexia SAS.

Item 16G. Corporate Governance. 

As  a  French  société  anonyme,  the  Company  is  subject  to  various  corporate  governance  requirements 
under French law. The Company is a “foreign private issuer” under the U.S. federal securities laws and 
the Nasdaq listing rules. As a foreign private issuer listed on the Nasdaq Global Market, we are subject to 
the  Nasdaq  corporate  governance  listing  standards.  However,  the  Nasdaq  Global  Market’s  listing 
standards  provide  that  foreign  private  issuers,  as  defined  in  the  rules  promulgated  under  the  Exchange 
Act,  are  permitted  to  follow  home  country  corporate  governance  practices  instead  of  certain  Nasdaq 
listing requirements, with certain exceptions. A foreign private issuer that elects to follow a home country 
practice  instead  of  Nasdaq  listing  requirements  must  submit  to  Nasdaq  a  written  statement  from  an 

235

independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited 
by the home country’s laws. 

The  Company  applies  the  Middlenext  code,  which  recommends  that  at  least  two  members  of  the 
Supervisory Board be independent (as such term is defined under the code). Certain corporate governance 
practices  in  France  may  differ  significantly  from  Nasdaq’s  corporate  governance  listing  standards. 
Neither  the  corporate  laws  of  France  nor  the  bylaws  requires  that  (i)  a  majority  of  the  members  of  our 
Supervisory  Board  be  independent,  (ii)  each  committee  of  the  Supervisory  Board  has  a  formal  written 
charte  or  (iii)  the  independent  members  of  the  Supervisory  Board  hold  regularly  scheduled  meetings  at 
which only independent members of the Supervisory Board are present. Other than as set forth below, the 
Company currently  intends to comply with the corporate governance listing standards of Nasdaq to the 
extent  possible  under  French  law.  However,  we  may  choose  to  change  such  practices  to  follow  home 
country practice in the future. 

Although we are a foreign private issuer, these exemptions do not modify the independence requirements 
for the Audit Committee. Pursuant to the requirements of the Sarbanes-Oxley Act of 2002 and the Nasdaq 
Listing  Rules,  our  Audit  Committee  must  be  composed  of  at  least  three  independent  members.  Rule 
10A-3 under the Exchange Act provides that the Audit Committee must have direct responsibility for the 
nomination,  compensation  and  choice  of  the  auditors,  as  well  as  control  over  the  performance  of  their 
duties, management of complaints made, and selection of consultants. Under Rule 10A-3, if the laws of a 
foreign private issuer’s home country require that any such matter be approved by our Supervisory Board 
or  the  shareholders  of  the  Company,  the  Audit  Committee’s  responsibilities  or  powers  with  respect  to 
such matter may instead be advisory. Under French law, the Audit Committee may only have an advisory 
role and appointment of the statutory auditors, in particular, must be decided by the shareholders at the 
annual meeting. 

In addition, Nasdaq Listing Rules require that a listed company specify that the quorum for any meeting 
of the holders of share capital be at least 33 1/3% of the outstanding shares of the company’s ordinary 
voting shares. The Company intends to follow its French home country practice, rather than complying 
with  this  Nasdaq  Listing  Rule.  Consistent  with  French  Law,  the  Company's  bylaws  provide  that  when 
first convened, general meetings of shareholders may validly convene only if the shareholders present or 
represented hold at least (1) 20% of the voting shares in the case of an ordinary general meeting or of an 
extraordinary  general  meeting  where  shareholders  are  voting  on  a  capital  increase  by  capitalization  of 
reserves, profits or share premium, or (2) 25% of the voting shares in the case of any other extraordinary 
general meeting. If such quorum required by French law is not met, the meeting is adjourned. There is no 
quorum  requirement  under  French  law  when  an  ordinary  general  meeting  or  an  extraordinary  general 
meeting is reconvened where shareholders are voting on a capital increase by capitalization of reserves, 
profits  or  share  premium,  but  the  reconvened  meeting  may  consider  only  questions  that  were  on  the 
agenda  of  the  adjourned  meeting.  When  any  other  extraordinary  general  meeting  is  reconvened,  the 
required  quorum  under  French  law  is  20%  of  the  shares  entitled  to  vote.  The  reconvened  meeting  may 
consider  only  questions  that  were  on  the  agenda  of  the  adjourned  meeting.  If  a  quorum  is  not  met  at  a 
reconvened  meeting  requiring  a  quorum,  then  the  meeting  may  be  adjourned  for  a  maximum  of  two 
months.

Finally, the Company follows French law with respect to shareholder approval requirements in lieu of the 
various shareholder approval requirements of Nasdaq Listing Rule 5635, which requires a Nasdaq listed 
company to obtain shareholder approval prior to certain issuances of securities, including: (a) issuances in 
connection  with  the  acquisition  of  the  stock  or  assets  of  another  company  if  upon  issuance  the  issued 
shares will equal 20% or more of the number of shares or voting power outstanding prior to the issuance, 
or  if  certain  specified  persons  have  a  5%  or  greater  interest  in  the  assets  or  company  to  be  acquired 
(Nasdaq Listing Rule 5635(a)); (b) issuances or potential issuances that will result in a change of control 

236

of us (Nasdaq Listing Rule 5635(b)); (c) issuances in connection with equity compensation arrangements 
(Nasdaq  Listing  Rule  5635(c));  and  (d)  20%  or  greater  issuances  in  transactions  other  than  public 
offerings,  as  defined  in  the  Nasdaq  rules  (Nasdaq  Listing  Rule  5635(d)).  Under  French  law,  the 
Company’s  shareholders may approve issuances of equity, as a general matter, through the adoption  of 
delegation  of  authority  resolutions  at  the  Company’s  shareholders’  meeting  pursuant  to  which 
shareholders may delegate their authority to the Executive Board to increase the Company’s share capital 
within specified parameters set by the shareholders, which may include a time limitation to carry out the 
share  capital  increase,  the  cancellation  of  their  preferential  subscription  rights  to  the  benefit  of  named 
persons or a category of persons, specified price limitations and/or specific or aggregate limitations on the 
size  of  the  share  capital  increase.  Due  to  differences  between  French  law  and  corporate  governance 
practices and Nasdaq Listing Rule 5635, the Company follows French home country practice, rather than 
complying with this Nasdaq Listing Rule.

In accordance with French law, committees of our Supervisory Board will only have an advisory role and 
can  only  make  recommendations  to  our  Supervisory  Board.  As  a  result,  decisions  will  be  made  by  our 
Supervisory  Board  taking  into  account  nonbinding  recommendations  of  the  relevant  Supervisory  Board 
committee.

Item 16K. Cybersecurity

In order to assess, identify and manage material risks from cybersecurity threats, the Company maintains 
a  cybersecurity  roadmap,  which  includes  processes  for  information  technology,  or  IT,  operations, 
technologies, business continuity and governance. The cybersecurity roadmap is based on an assessment 
performed by a third-party consultant. 

To  assess  and  manage  material  cybersecurity  risks,  the  Company  has  established  a  dedicated  steering 
committee, chaired by the Vice President, Compliance & Operations, who has managed the Company’s 
cybersecurity strategy since 2020, including representatives from Innate’s IT and compliance functions, 
the Chief Financial Officer and the relevant business functions. The steering committee’s responsibilities 
include  defining  priorities,  endorsing  the  cybersecurity  roadmap,  overseeing  execution  of  the 
cybersecurity roadmap, and monitoring the ongoing implementation of our risk management strategy for 
IT infrastructure, systems, vendors, and regulatory compliance. The steering committee is responsible for 
tracking cybersecurity incidents, preparing mitigation plans, and managing any significant events related 
to  cybersecurity.  In  support  of  objectivity  and  segregation  of  duties,  the  coordination  of  cybersecurity 
activities  described  above  is  assigned  to  a  function  independent  of  IT,  hosted  in  the  Compliance 
department  of  Innate  including  with  a  person  who  was  previously  the  Head  of  Information  Systems  & 
Technology  at  Innate  Pharma.  Employees  at  each  level  of  the  organization  receive  regular  training 
sessions about cybersecurity risks. Moreover, the company relies on external specialists and vendors for 
technical  matters  for  which  it  has  limited  skills  or  infrastructure.  All  external  subcontractors  and  IT 
systems that manage sensitive processes or data are selected taking into account cybersecurity and data 

237

protection  considerations,  in  particular  by  checking  the  certifications  held  by  service  providers  or 
suppliers and performing, when appropriate, qualification and follow-up audits.

At Innate Pharma, cybersecurity risks are integrated within our overall risk management framework. Each 
year,  the  Vice  President,  Compliance  &  Operations  gathers  input  from  various  stakeholders  at  the 
Company and identifies the risks facing our business and regularly presents the identified material risks, 
including cybersecurity risks to the Audit Committee. This reporting covers various matters, including the 
cybersecurity  risks  identified  and  proposed  mitigation  or  preventative  measures.  Our  risk  assessment  is 
performed regularly and is subject to change in case of any significant change or event during the year. In 
case  of  a  significant  cybersecurity  incident,  the  cybersecurity  steering  committee  would  assess  the 
incident severity, propose the appointment of an appropriate crisis unit and submit an action plan for the 
Executive Board’s endorsement. If the incident is considered as critical to the Company’s cybersecurity, 
the incident will be escalated to the Audit Committee and to the Supervisory Board.

As  of  the  filing  of  this  Form  20-F,  the  Company  is  not  aware  of  any  cyber-attacks  that  have  occurred 
since the beginning of 2023 that have materially affected, or are reasonably likely to materially affect the 
Company, including its business strategy, results of operations or financial condition. Although we have 
put in place the cybersecurity processes described above, we remain exposed to cybersecurity attacks and 
incidents  and  misuse  or  manipulation  of  any  of  our  IT  systems,  which  could  have  a  material  adverse 
effect  on  our  business  strategy,  results  of  operations  or  financial  condition.  See  “Risk  Factors  –  Risks 
Related to Innate Pharma's Organization and Operations” in Item 3.D. of this Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Innate Pharma S.A.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Innate Pharma S.A. and subsidiaries 
(the  "Company")  as  of  December  31,  2023,  2022  and  2021,  the  related  consolidated  statements  of  
income,  comprehensive  income,  shareholders'  equity,  and  cash  flows,  for  each  of  the  three  years  in  the 
period  ended  December  31,  2023,  and  the  related  notes    (collectively  referred  to  as  the  "financial 
statements"). In our opinion, the financial statements present fairly, in all material respects, the financial 
position of the Company as of December 31, 2023, 2022 and 2021, and the results of its operations and its 
cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2023,  in  conformity  with 
International Financial Reporting Standards as issued by the International Accounting Standards Board.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to 
express  an  opinion  on  the  Company's  financial  statements  based  on  our  audits.  We  are  a  public 
accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. 
federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange 
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that 
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are 
free of material misstatement, whether due to error or fraud. The Company is not required to have, nor 
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, 
we  are  required  to  obtain  an  understanding  of  internal  control  over  financial  reporting  but  not  for  the 
purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial 
reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial 
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the 
financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant 
estimates made by management, as well as evaluating the overall presentation of the financial statements. 
We believe that our audits provide a reasonable basis for our opinion.

Note 1: The company

NOTES TO FINANCIAL STATEMENTS

Innate  Pharma  SA  (the  “Company”  and,  with  its  subsidiary,  referred  to  as  the  “Group”),  is  a  global, 
clinical-stage  biotechnology  company  developing  immunotherapies  for  cancer  patients.  Its  innovative 
approach  aims  to  harness  the  innate  immune  system  through  therapeutic  antibodies  and  its  ANKET® 
(Antibody-based  NK  cell  Engager  Therapeutics)  proprietary  platform.  Innate’s  portfolio  includes  lead 
proprietary  program  lacutamab,  developed  in  advanced  form  of  cutaneous  T  cell  lymphomas  and 
peripheral T cell lymphomas, monalizumab developed with AstraZeneca in non small cell lung cancer, as 
well  as  ANKET®  multi-specific  NK  cell  engagers  to  address  multiple  tumor  types.  The  Company  has 
developed,  internally  and  through  its  business  development  strategy,  a  broad  and  diversified  portfolio 
including  seven  clinical  drug  candidates  and  a  robust  preclinical  pipeline.  Innate  has  entered  into 
collaborations  with  leaders  in  the  biopharmaceutical  industry,  such  as  AstraZeneca,Sanofi  and  Takeda. 
Innate  Pharma  believes  its  drug  candidates  and  clinical  development  approach  are  differentiated  from 
current immuno-oncology therapies and have the potential to significantly improve the clinical outcome 
for patients with cancer.

From  its  inception,  the  Company  has  incurred  losses  due  to  its  research  and  development  (“R&D”) 
activity.  The  financial  year  ended  December  31,  2023  generated  a  €7,570  thousand  net  loss.  As  of 
December  31,  2023,  the  shareholders’  equity  amounted  to  €51,901  thousand.  Subject  to  potential  new 
milestone payments related to its collaboration agreements, the Company anticipates incurring additional 
losses  until  such  time,  if  ever,  that  it  can  generate  significant  revenue  from  its  product  candidates  in 
development. 

The  Company’s  future  operations  are  highly  dependent  on  a  combination  of  factors,  including:  (i)  the 
success  of  its  R&D;  (ii)  regulatory  approval  and  market  acceptance  of  the  Company’s  future  drug 
candidates; (iii) the timely and successful completion of additional financing; and (iv) the development of 
competitive therapies by other biotechnology and pharmaceutical companies. As a result, the Company is 
and  should  continue,  in  the  short  to  mid-term,  to  be  financed  through  partnership  agreements  for  the 
development  and  commercialization  of  its  drug  candidates  and  through  the  issuance  of  new  equity 
instruments.

The Company’s activity is not subject to seasonal fluctuations. 

As  of  December  31,  2023,  the  Company  had  one  wholly  owned  subsidiary:  Innate  Pharma,  Inc., 
incorporated under the laws of Delaware in 2009.

This subsidiary is fully consolidated.

1.1.

Significant contracts

The following paragraphs describe the key provisions of significant contracts.

a)

Agreements related to monalizumab with Novo Nordisk A/S and with AstraZeneca 

2014 Novo Nordisk A/S monalizumab agreement

On  February  5,  2014,  the  Company  acquired  from  Novo  Nordisk  A/S  full  development  and 
commercialization rights to monalizumab. Novo Nordisk A/S received €2.0 million in cash and 600,000 
ordinary shares at a price of €8.33 per share (€5.0 million). Novo Nordisk A/S is eligible to receive up to 
€20.0 million in potential regulatory milestones and single-digit tiered royalties on sales of monalizumab 
products. The agreement with Novo Nordisk A/S included a right to additional consideration in the event 

F-9

of an out-licensing agreement. Consequently, following the agreement signed with AstraZeneca in April 
2015  (as  described  below),  the  Company  paid  to  Novo  Nordisk  A/S  additional  consideration  of 
€6.5 million (paid in April 2016). Following the exercise of the option by AstraZeneca in October 2018 
(as  described  below),  Novo  Nordisk  A/S  became  entitled  to  a  second  and  final  additional  payment 
amounting to $15.0 million (€13.1 million) which was recognized as a liability as of December 31, 2018 
and was paid in February 2019. There are no other potential additional milestones payments due to Novo 
Nordisk A/S. These amounts were added to the net book value of the intangible asset and are amortized 
according to the same amortization plan as the initial €7.0 million recognized in 2014. The net book value 
of the license amounted to €0.4 million as of December 31, 2023. 

Refer to Notes 2.h, 2.j and 6 for accounting description. 

2015 AstraZeneca monalizumab agreements

Under co-development and option agreements signed with AstraZeneca in 2015, the Company granted to 
AstraZeneca an exclusive license, subject to certain exclusions, to certain of its patents and know-how to 
develop,  manufacture  and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of 
diagnosis, prevention and treatment of oncology diseases and conditions. The Company further granted to 
AstraZeneca  a  worldwide,  non-exclusive  license  to  certain  of  its  other  patents  to  develop,  manufacture 
and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis,  prevention  and 
treatment of oncology diseases and conditions. 

The Company received an initial payment of $250 million under these agreements in June 2015, of which 
$100  million  was  paid  to  the  Company  as  an  initial  payment  for  the  co-development  agreement  and 
$150 million was paid to the Company as consideration for the option agreement. On October 22, 2018, 
AstraZeneca exercised this option, triggering the payment of $100.0 million, which was received by the 
Company in January 2019. 

Following  the  option  exercise,  AstraZeneca  became  the  lead  party  in  developing  the  licensed  products 
and  must  use  commercially  reasonable  efforts  to  develop,  obtain  regulatory  approval  for  and 
commercialize each licensed product in certain major markets. 

In  July  31,  2019,  the  Company  notified  AstraZeneca  of  its  decision  to  co-fund  a  future  monalizumab 
Phase 3 clinical development program.

In  September  2020,  the  Company  signed  an  amendment  to  the  collaboration  and  license  agreement 
concluded with AstraZeneca in 2015. Following the analysis of a longer patient follow-up as well as the 
maturation  of  the  survival  data  of  the  Cohort  2,  and  after  discussion  with  AstraZeneca,  the  Company 
agreed  to  amend  the  original  agreement.  This  amendment  changed  the  financial  terms  relating  to  the 
milestone  payment  expected  following  the  treatment  of  the  first  patient  with  AstraZeneca  in  the  first 
Phase  3  trial  evaluating  monalizumab.  The  original  agreement  signed  in  2015  provided  for  a  milestone 
payment of $100 million. Following the inclusion by AstraZeneca of the first patient in the first Phase 3 
trial evaluating monalizumab (INTERLINK-1) in October 2020, and in accordance with the amendment 
signed in September 2020, the Company received a payment of $50 million . An additional payment of 
$50  million  was  subject  to  an  interim  analysis.  On  August  1,  2022,  the  Company  announced  that  the 
combination  of  monalizumab  and  cetuximab  did  not  reach  the  pre-specified  efficacy  threshold  in  the 
protocol-planned  interim  futility  analysis  of  the  Phase  3  INTERLINK-1  clinical  study  conducted  by 
AstraZeneca.  AstraZaneca  has  thus  informed  the  Company  that  the  study  will  be  discontinued. 
Consequently, the Company is not eligible for the additional payment of $50.0 million as provided for in 
the amendment signed in September 2020. 

F-10

On  June  2022,  the  Company  received  an  additionnal  payment  of  $50.0  million  from  AstraZeneca 
following  the  inclusion  of  the  first  patient  in  the  second  trial  evaluating  monalizumab,  on  April  2022 
("PACIFIC-9").

In addition to the initial payment, the option exercise payment and the payment received for the inclusion 
of  the  first  patient  in  the  first  Phase  3  trial,  AstraZeneca  is  obligated  to  pay  the  Company  up  to 
$775  million  in  the  aggregate  upon  the  achievement  of  certain  development  and  regulatory  milestones 
($350  million)  and  commercialization  milestones  ($425  million).  The  Company  is  eligible  to  receive 
tiered royalties ranging from a low double-digit to mid-teen percentage on net sales of licensed products 
outside of Europe. The Company is required for a defined period of time to co-fund 30% of the Phase 3 
clinical trials of licensed products, subject to an aggregate cap, in order to receive 50% of the profits in 
Europe. 

Refer to Notes 2.p and 13.a for accounting description. 

b)

Agreement related to Lumoxiti with AstraZeneca

In October 2018, the Company obtained an exclusive license from AstraZeneca under certain patents and 
know-how  to  develop,  manufacture  and  commercialize  Lumoxiti  for  all  uses  in  humans  and  animals  in 
the  United  States,  the  European  Union  and  Switzerland.  Under  this  Agreement,  AstraZeneca  was 
obligated  to  provide  support  for  the  continued  development  and  commercialization  of  Lumoxiti  in  the 
European Union and Switzerland prior to regulatory submission and approval as well as support for the 
continued  commercialization  of  Lumoxiti  in  the  United  States  for  a  specified  period  running  until 
September  30,  2020.  Following  this  transition  period,  the  company  took  charge  of  all  marketing  of 
Lumoxiti in the United States. 

Under the agreement signed in 2018, the Company was obligated to pay a $50.0 million initial payment 
(€43.8 million), which it paid in January 2019, and a $15.0 million regulatory milestone (€13.4 million), 
which  was  paid  in  January  2020.  The  Company  has  reimbursed  reimburse  AstraZeneca  for  the 
development,  production  and  commercialization  costs  it  incurs  during  the  transition  period,  ended  in 
September 30, 2020.

Further  to  the  decision  to  terminate  the  Lumoxiti  Agreement  and  termination  notice  sent  in  December 
2020, a termination and transition agreement was discussed and executed, effective as of June 30, 2021 
terminating  the  Lumoxiti  Agreement  as  well  as  Lumoxiti  related  agreements  (including  the  supply 
agreement,  the  quality  agreement  and  other  related  agreements)  and  transferring  of  the  U.S.  marketing 
authorization  and  distribution  rights  of  Lumoxiti  back  to  AstraZeneca.  The  FDA  has  effectively 
transferred the BLA to AstraZeneca on February 8, 2022. AstraZeneca has reimbursed Innate Pharma for 
all Lumoxiti related costs, expenses and benefited net sales. In the year ended December 31, 2020 results 
announcement,  the  Company  reported  a  contingent  liability  of  up  to  $12.8  million  in  its  consolidated 
financial  statements,  which  was  related  to  the  splitting  of  certain  manufacturing  costs.  As  part  of  the 
termination and transition agreement, Innate and AstraZeneca agreed to split these manufacturing costs, 
and Innate has paid $6.2 million to AstraZeneca (€5.9 million) on April 2022.

Following the termination and transition agreement signed in 2021, Lumoxiti activities are presented as 
discontinued operations as of December 31, 2021 and 2022, respectively. As of December 31, 2023, the 
transition of all Lumoxiti rights and the transfer of activities to AstraZeneca has been fully completed.

Refer to Notes 2.v and 17 for accounting description. 

c)

Agreement related to IPH5201 with AstraZeneca 

In  October  2018,  the  Company  signed  a  collaboration  and  option  agreement  with  AstraZeneca  for  co-
development  and  co-commercialization  of  IPH5201.  Under  the  agreement,  AstraZeneca  paid  the 

F-11

Company a $50.0 million upfront payment ($26.0 million paid in October 2018 and $24.0 million paid in 
January 2019), and a milestone payment of $5.0 million paid in June 2020 following the assay of the first 
patient in the first Phase 1 trial evaluating IPH5201, in March 2020. AstraZeneca is obligated to pay the 
Company up to an aggregate of $5.0 million upon the achievement of certain development milestones. 

On June 1, 2022, the Company signed an amendment to the collaboration and license option agreement 
IPH5201 concluded with AstraZeneca in October 2018. Subsequently, the Company announced on June 
3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung cancers for which the Company will 
be the sponsor. In accordance with the amendment signed on June 1, 2022, the Company is eligible for a 
milestone payment of $5.0 million by AstraZeneca. This milestone payment was received on August 2, 
2022 by the Company. 

Upon exercise of its option under the agreement, AstraZeneca is committed to pay an option exercise fee 
of $25.0 million and up to $800.0 million in the aggregate upon the achievement of certain development 
and  regulatory  milestones  ($300  million)  and  commercialization  milestones  ($500  million).  The 
arrangement  also  provides  for  a  50%  profit  share  in  Europe  if  the  Company  opts  into  certain  co-
promoting and late stage co-funding obligations. In addition, the Company would be eligible to receive 
tiered royalties ranging from a high-single digit to mid-teen percentage on net sales of IPH5201, or from a 
mid-single digit to low-double digit percentage on net sales of other types of licensed products, outside of 
Europe.  The  royalties  payable  to  the  Company  under  the  agreement  may  be  reduced  under  certain 
circumstances, including loss of exclusivity or lack of patent protection. As of December 31, 2020, since 
the Company had fulfilled all of its commitments on preclinical work related to the start of Phase 1 of the 
IPH5201 program, the initial payment of $50.0 million and the milestone payment of $5.0 million were 
fully  recognized  in  revenue.  The  Company  was  reimbursed  by  AstraZeneca  for  certain  research  and 
development expenses related to IPH5201 for the year ended December 31, 2023. The Company has the 
option to co-fund 30% of the shared development expenses related to the Phase 3 clinical trials in order to 
acquire co-promotion rights and to share in 50% of the profits and losses of licensed products in Europe. 
If the Company does not opt into the co-funding obligations, among other things, its right to share in 50% 
of the profits and losses in Europe and right to co-promote in certain European countries will terminate 
and will be replaced by rights to receive royalties on net sales at the rates applicable to outside of Europe. 
Additionally,  certain  milestone  payments  that  may  be  payable  to  the  Company  would  be  materially 
reduced.

Refer to Notes 2.p and 13 for accounting description. 

d)

Agreement related to additional preclinical molecules with AstraZeneca

In October 2018, the Company granted to AstraZeneca four exclusive options that are exercisable until 
IND  approval  to  obtain  a  worldwide,  royalty-bearing,  exclusive  license  to  certain  of  the  Company’s 
patents  and  know-how  relating  to  certain  specified  pipeline  candidates  to  develop  and  commercialize 
optioned  products  in  all  fields  of  use.  Pursuant  to  the  agreement,  AstraZeneca  paid  the  Company  a 
$20.0  million  upfront  payment  (€17.4  million)  in  October  2018.  The  Company  recognized  this  upfront 
payment in the consolidated statement of financial position as deferred revenue as of December 31, 2018, 
until the exercise or the termination of each option at the earliest. 

During 2022 first semester, the Company received from AstraZeneca a notice that it will not exercise its 
option  to  license  the  four  preclinical  programs  covered  in  the  "Future  Programs  Option  Agreement". 
Innate has now regained full rights to further develop the four preclinical molecules. Consequently, the 
entire initial payment of $20.0 million, or €17.4 million was recognized as revenue as of June 30, 2022

Collaboration and license agreements concluded with Sanofi for the development of "NK Cell 

f)
engages" in oncology

License and collaboration agreement with Sanofi signed in 2016

On January 2016, the Company entered into a research collaboration and licensing agreement with Sanofi 
to apply its proprietary technology to the development of multi-specific antibody formats engaging NK 
cells  to  kill  tumor  cells  through  the  activating  receptor  NKp46.  The  Company  granted  to  Sanofi  under 
certain of its intellectual property a non-exclusive, worldwide, royalty-free research license, as well as an 
exclusive,  worldwide  license  to  research,  develop  and  commercialize  products  directed  against  two 
specified targets, for all therapeutic, prophylactic and diagnostic indications and uses. 

The Company had work together with Sanofi on the generation and evaluation to two multispecific NK 
cell  engagers  (IPH6101/SAR443579  and  IPH6401/SAR'514),  using  its  technology  and  Sanofi’s  tumor 
targets  and  technology.  Under  the  terms  of  the  license  agreement,  Sanofi  will  be  responsible  for  the 
development, manufacturing and commercialization of products resulting from the research collaboration. 
The Company will be eligible for up to €400.0 million in payments, primarily upon the achievement of 
development  and  commercial  milestones,  as  well  as  royalties  ranging  from  a  mid  to  high  single-digit 
percentage on net sales.

On  January  5,  2021,  the  Company  announced  that  Sanofi  has  made  the  decision  to  progress  IPH6101/
SAR443579  into  investigational  new  drug  (IND)  enabling  studies.  IPH6101/SAR443579  is  a  NKp46-
based NK cell engager (NKCE) using Innate’s proprietary multi-specific antibody format. The decision 

F-13

triggered  a  €7.0m  milestone  payment  from  Sanofi  to  Innate.  Sanofi  will  be  responsible  for  all  future 
development,  manufacturing  and  commercialization  of  IPH6101/SAR443579.  In  December  2021,  the 
Company  announced  that  the  first  patient  was  dosed  in  a  Phase  1/2  clinical  trial,  evaluating  IPH6101/
SAR443579,  in  patients  with  relapsed  or  refractory  acute  myeloid  leukemia  (R/R  AML),  B-cell  acute 
lymphoblastic  leukemia  (B-ALL)  or  high  risk-myelodysplastic  syndrome  (HR-MDS).  Following  the 
initiation of the trial, the Company received a €3.0m milestone from Sanofi.

During  2022  first  semester,  the  Company  was  informed  of  Sanofi's  decision  to  advance  IPH6401/
SAR’514 towards regulatory preclinical studies aimed at studying an investigational new drug. As such, 
Sanofi  has  selected  a  second  multi-specific  antibody  that  engages  NK  cells  as  a  drug  candidate.  This 
selection triggered a €3.0 million milestone payment from Sanofi to the Company. On July 11, 2023, the 
company announced the dosing as of June 7, 2023, of the first in a Sanofi-sponsored Phase 1/2 clinical 
trial, evaluating IPH6401/SAR’514 in relapsed/refractory Multiple Myeloma. As a consequence, Sanofi 
made a milestone payment of €2.0 million to the Company.

Consolidation method

The  Group  applies  IFRS  10  Consolidated  financial  statements.  IFRS  10  presents  a  single  consolidation 
model identifying control as the criteria for consolidating an entity. An investor controls an investee if it 
has the power over the entity, is exposed or has rights to variable returns from its involvement with the 
entity and has the ability to use its power over the entity to affect the amount of the investor’s returns. 
Subsidiaries are entities over which the Company exercises control. They are fully consolidated from the 
date the Group obtains control and are deconsolidated from the date the Group ceases to exercise control. 
Intercompany balances and transactions are eliminated.

g)

Financial instruments

Financial assets

Financial assets are initially measured at fair value plus directly attributable transaction costs in the case 
of instruments not measured at fair value through profit or loss. Directly attributable transaction costs of 
financial assets measured at fair value through profit or loss are recorded in the consolidated statement of 
income (loss).

Under IFRS 9, financial assets are classified in the following three categories:

•

•

•

Financial assets at amortized cost;

Financial assets at fair value through other comprehensive income (“FVOCI”); and

Financial assets at fair value through profit or loss.

The classification of financial assets depends on:

•

•

The characteristics of the contractual cash flows of the financial assets; and

The business model that the entity follows for the management of the financial asset.

Financial assets at amortized cost

Financial assets are measured at amortized cost when (i) they are not designated as financial assets at fair 
value through profit or loss, (ii) they are held within a business model whose objective is to hold assets in 
order to collect contractual cash flows and (iii) they give rise to cash flows that are solely payments of 
principal  and  interest  on  the  principal  amount  outstanding  (“SPPI”  criterion).  They  are  subsequently 
measured  at  amortized  cost,  determined  using  the  effective  interest  method  (“EIR”),  less  any  expected 
impairment  losses  in  relation  to  the  credit  risk.  Interest  income,  exchange  gains  and  losses,  impairment 
losses  and  gains  and  losses  arising  on  derecognition  are  all  recorded  in  the  consolidated  statement  of 
income (loss). 

This  category  primarily  includes  trade  receivables,  as  well  as  other  loans  and  receivables.  Long-term 
loans  and  receivables  that  are  not  interest-bearing  or  that  bear  interest  at  a  below-market  rate  are 
discounted when the amounts involved are material. 

Financial assets at fair value through other comprehensive income 

Financial assets  at fair value through other comprehensive income is mainly comprised is composed  of 
debt instruments whose contractual cash flows represent payments of interest or repayments of principal, 
and which are managed with a view to collecting cash flows and selling the asset. Gains and losses arising 
from changes in fair value are recognized in equity within the statement of comprehensive income in the 
period  in  which  they  occur.  When  such  assets  are  derecognized,  the  cumulative  gains  and  losses 
previously  recognized  in  equity  are  reclassified  to  profit  or  loss  for  the  period  within  the  line  items 
Financial income or Financial expenses. The Company did not hold this type of instrument as of January 
1, 2023 or as of December 31, 2023.

F-20

Financial assets at fair value through profit or loss 

Financial assets at fair value through profit or loss is comprised of:

•

•

financial assets that are not part of the above categories; and

instruments  that  management  has  designated  as  “fair  value  through  profit  or  loss”  on  initial 
recognition.

Gains and losses arising from changes in fair value are recognized in profit or loss within the line items 
financial income or financial expenses.

Impairment of financial assets measured at amortized cost

The  main  assets  involved  are  trade  receivables  and  others.  Trade  receivables  are  recognized  when  the 
Company has an unconditional right to payment by the customer. Impairment losses on trade receivables 
and others are estimated using the expected loss method, in order to take account of the risk of payment 
default throughout the lifetime of the receivables. The expected credit loss is estimated collectively for all 
accounts receivable at each reporting date using an average expected loss rate, determined primarily on 
the basis of historical credit loss rates. However, that average expected loss rate may be adjusted if there 
are indications of a likely significant increase in credit risk. If a receivable is subject to a known credit 
risk,  a  specific  impairment  loss  is  recognized  for  that  receivable.  The  amount  of  expected  losses  is 
recognized  in  the  balance  sheet  as  a  reduction  in  the  gross  amount  of  accounts  receivable.  Impairment 
losses on accounts receivable are recognized within Operating expenses in the consolidated statement of 
income (loss).

Financial liabilities

Financial  liabilities  comprise  deferred  revenue,  collaboration  liabilities,  loans  and  trade  and  other 
payables.

Financial  liabilities  are  initially  recognized  on  the  transaction  date,  which  is  the  date  that  the  Company 
becomes  a  party  to  the  contractual  provisions  of  the  instrument.  They  are  derecognized  when  the 
Company’s contractual obligations are discharged, cancelled or expire.

Loans  are  initially  measured  at  fair  value  of  the  consideration  received,  net  of  directly  attributable 
transaction  costs.  Subsequently,  they  are  measured  at  amortized  cost  using  the  EIR  method.  All  costs 
related to the issuance of loans, and all differences between the issuance proceeds net of transaction costs 
and  the  value  on  redemption,  are  recognized  within  financial  expenses  in  the  consolidated  statement  of 
income (loss) over the term of the debt using the EIR method.

Other financial liabilities include trade accounts payable, which are measured at fair value (which in most 
cases equates to face value) on initial recognition, and subsequently at amortized cost. 

Cash and cash equivalents

Cash equivalents are short-term, highly liquid investments, that are readily convertible to known amounts 
of  cash  and  which  are  subject  to  an  insignificant  risk  of  changes  in  value.  Cash  and  cash  equivalents 
comprise the cash that is held at the bank and petty cash as well as the short-term fixed deposits for which 
the maturity is less than three months. 

For  the  purpose  of  establishing  the  statement  of  cash  flows,  cash  and  cash  equivalents  include  cash  in 
hand, demand deposits and short fixed-term deposits with banks and short-term highly liquid investments 
with original maturities of three months or less, net of bank overdrafts. 

Cash and cash equivalents are initially recognized at their purchase costs on the transaction date, and are 
subsequently measured at fair value. Changes in fair value are recognized in profit or loss.

F-21

Fair value of financial instruments

Under  IFRS  13  Fair  value  measurement  and  IFRS  7  Financial  instruments:  disclosures,  or  IFRS  7,  fair 
value  measurements  must  be  classified  using  a  hierarchy  based  on  the  inputs  used  to  measure  the  fair 
value of the instrument. This hierarchy has three levels:

•

•

•

level  1:  fair  value  calculated  using  quoted  prices  in  an  active  market  for  identical  assets  and 
liabilities;

level 2: fair value calculated using valuation techniques based on observable market data such 
as prices of similar assets and liabilities or parameters quoted in an active market; and

level 3: fair value calculated using valuation techniques based wholly or partly on unobservable 
inputs  such  as  prices  in  an  inactive  market  or  a  valuation  based  on  multiples  for  unlisted 
securities.

h)

Intangible assets

Research and development (R&D) expenses

In accordance with IAS 38 Intangible assets, or IAS 38, expenses on research activities are recognized as 
an expense in the period in which it is incurred. 

An internally generated intangible asset arising from the Company’s development activities is recognized 
only if all of the following conditions are met:

•

•

•

•

Technically feasible to complete the intangible asset so that it will be available for use or sale;

The Company has the intention to complete the intangible assets and use or sell it;

The Company has the ability to use or sell the intangible assets;

The intangible asset will generate probable future economic benefits, or indicate the existence 
of a market;

• Adequate  technical,  financial  and  other  resources  to  complete  the  development  are  available; 

and

•

The  Company  is  able  to  measure  reliably  the  expenditure  attributable  to  the  intangible  asset 
during its development.

Because of the risks and uncertainties related to regulatory approval, the R&D process and the availability 
of technical, financial and human resources necessary to complete the development Phases of the product 
candidates, the six criteria for capitalization are usually considered not to have been met until the product 
candidate  has  obtained  marketing  approval  from  the  regulatory  authorities.  Consequently,  internally 
generated development expenses arising before marketing approval has been obtained, mainly the cost of 
clinical trials, are generally expensed as incurred within Research and development expenses.

However,  some  clinical  trials,  for  example  those  undertaken  to  obtain  a  geographical  extension  for  a 
molecule that has already obtained marketing approval in a major market, may in certain circumstances 
meet the six capitalization criteria under IAS 38, in which case the related expenses are recognized as an 
intangible  asset.  These  related  costs  are  capitalized  when  they  are  incurred  and  amortized  on  a  straight 
line basis over their useful lives beginning when marketing approval is obtained.

Licenses

Payments  for  separately  acquired  research  and  development  are  capitalized  within  “Other  intangible 
assets” provided that they meet the definition of an intangible asset: a resource that is (i) controlled by the 

F-22

Group,  (ii)  expected  to  provide  future  economic  benefits  for  the  Group  and  (iii)  identifiable  (i.e.  it  is 
either separable or arises from contractual or legal rights).

In  accordance  with  paragraph  25  of  IAS  38  standard,  the  first  recognition  criterion,  relating  to  the 
likelihood of future economic benefits generated by the intangible asset, is presumed to be achieved for 
research and development activities when they are acquired separately. 

In  this  context,  amounts  paid  to  third  parties  in  the  form  of  initial  payments  or  milestone  payments 
relating  to  product  candidates  that  have  not  yet  obtained  a  regulatory  approval  are  recognized  as 
intangible assets. These rights are amortized on a straight-line basis: 

(i) after obtaining the regulatory approval, over their useful life; or

(ii) after  entering  in  an  out-license  collaboration  agreement  with  a  third-party  partner,  over  their 
estimated useful life. This estimated useful life takes into consideration the period of protection 
of the out-licensed exclusivity rights and the anticipated period over which the Company will 
receive the economic benefits of the asset.

Unamortized  rights  (before  marketing  authorization)  are  subject  to  impairment  tests  in  accordance  with 
the method defined in Note 6.

When intangible assets acquired separately are acquired through variable or conditional payments, these 
payments are recognized as an increase of the carrying amount of the intangible asset when they become 
due.  Royalties  due  by  the  Company  related  to  acquired  licenses  are  recognized  as  operating  expenses 
when the Company recognizes sales subject to royalties. 

Estimate of the useful life of the acquired licenses: intangible assets are amortized on a straight line basis 
over  their  anticipated  useful  life.  The  estimated  useful  life  is  the  period  over  which  the  asset  provides 
future  economic  benefits.  It  is  estimated  by  management  and  is  regularly  revised  by  taking  into 
consideration  the  period  of  development  over  which  it  expects  to  receive  economic  benefits  such  as 
collaboration  revenues,  royalties,  product  of  sales,  etc.  However,  given  the  uncertainty  surrounding  the 
duration  of  the  R&D  activities  for  the  programs  in  development  and  their  likelihood  to  generate  future 
economic  benefits  to  the  Company,  the  estimated  useful  life  of  the  rights  related  to  these  programs  is 
rarely  longer  than  the  actual  development  Phase  of  the  product  candidate.  When  a  program  is  in 
commercialization Phases, the useful life takes into account the protection of the exclusivity rights and the 
anticipated period of commercialization without taking into account any extension or additional patents. 
The  prospective  amendment  of  the  amortization  plan  of  the  monalizumab  intangible  asset,  which  is 
modified according to the estimate ending date of the Phase 2 clinical trial is described in Note 6.

Other intangible assets

Other intangible assets consist of acquired software. Costs related to the acquisition of software licenses 
are recognized as assets based on the costs incurred to acquire and set up the related software. Software is 
amortized using the straight-line method over a period of one to three years depending on the anticipated 
period of use.

i)

Property and equipment

Property and equipment are carried at acquisition cost. Major renewals and improvements are capitalized 
while repairs and maintenance are expensed as incurred.

Property  and  equipment  are  depreciated  over  their  estimated  useful  lives  using  the  straight-line 
depreciation  method.  Leasehold  improvements  are  depreciated  over  the  life  of  the  improvement  or  the 
remaining lease term, whichever is shorter.

F-23

The  headquarters  of  the  Company  was  split  into  several  components  (e.g.,  foundations,  structure, 
electricity, heating and ventilation systems) which are depreciated over different useful lives according to 
the anticipated useful life of these elements.

Depreciation periods are as follows:

Buildings and improvements on buildings   .......................................................................... 20 to 40 years
Installations    .........................................................................................................................
5 to 20 years
Technical installations and equipment    ................................................................................
8 years
Equipment and office furniture    ...........................................................................................
5 years
Computers and IT equipment    ..............................................................................................
3 years

j)

Impairment of intangible assets, property, and equipment

The  Group  assesses  at  the  end  of  each  reporting  period  whether  there  is  an  indication  that  intangible 
assets,  property  and  equipment  may  be  impaired.  If  any  indication  exists,  the  Group  estimates  the 
recoverable amount of the related asset.

Whether or not there is any indication of impairment, intangible assets not yet available for use are tested 
for impairment annually by comparing their carrying amount with their recoverable amount. 

Pursuant to IAS 36—Impairment of Assets, criteria for assessing indication of loss in value may notably 
include performance levels lower than forecast, a significant change in market data and/or the regulatory 
environment,  the  asset  development  strategy  approved  by  management,  or  obsolescence  or  physical 
damage  of  the  asset  not  included  in  the  amortization/depreciation  schedule.  The  recognition  of  an 
impairment loss alters the amortizable/depreciable amount and potentially, the amortization/depreciation 
schedule of the relevant asset. 

Impairment  losses  on  intangible  assets,  property  and  equipment  shall  be  reversed  subsequently  if  the 
impairment loss no longer exists or has decreased. In such case, the recoverable amount of the asset is to 
be  determined  again  so  that  the  reversal  can  be  quantified.  The  asset  value  after  reversal  of  the 
impairment  loss  may  not  exceed  the  carrying  amount  net  of  depreciation/amortization  that  would  have 
been recognized if no impairment loss had been recognized in prior periods.

The  Group  does  not  have  any  intangible  assets  with  an  indefinite  useful  life.  However,  as  explained  in 
Note  2.h,  the  Group  recognized  intangible  assets  in  progress,  which  will  be  amortized  once  marketing 
authorization is received.

k)

Employee benefits

Long-term pension benefits

Company employees are entitled to pension benefits required by French law: 

•

•

Pension benefit, paid by the Company upon retirement (i.e. defined benefit plan); and

Pension payments from social security entities, financed by contributions from businesses and 
employees (i.e. defined contribution plan”).

In  addition,  the  Company  has  implemented  an  additional,  non-mandatory,  pension  plan  (“Article  83”), 
initially  for  the  benefit  of  executives  only.  This  plan  was  extended  to  the  non-executive  employees 
starting on January 1, 2014. This plan meets the definition of defined contribution plan and is financed 

F-24

through  a  contribution  that  corresponds  to  2.2%  of  the  employee’s  annual  wage,  with  the  Company 
paying 1.4% and the employee paying 0.8%. 

For  the  defined  benefit  plan,  the  costs  of  the  pension  benefit  are  estimated  using  the  “projected  unit 
credit” method. According to this method, the pension cost is accounted for in the consolidated statement 
of income (loss), so that it is distributed uniformly over the term of the services of the employees. The 
pension  benefit  commitments  are  valued  using  the  actual  present  value  of  estimated  future  payments, 
adopting the rate of interest of long-term bonds in the private sector (i.e. Euro zone AA or higher rated 
corporate bonds + 10 years). The difference between the amount of the provision at the beginning of a 
period and at the close of that period is recognized in the consolidated statement of income (loss) for the 
portion  representing  the  costs  of  services  rendered  and  the  net  interest  costs,  and  through  other 
comprehensive  income  for  the  portion  representing  the  actuarial  gains  and  losses.  The  Company’s 
commitments under the defined benefit plan are not covered by any plan assets. 

Payments  made  by  the  Company  for  defined  contribution  plans  are  accounted  for  as  expenses  in  the 
consolidated statement of income (loss) in the period in which they are incurred. 

Other long-term benefits

The  Company  pays  seniority  bonuses  to  employees  reaching  10,  15  and  20  years  of  seniority.  These 
bonuses represent long-term employee benefits. Under IAS 19R “Employee benefits”, they are recording 
as  a  defined  benefit  obligation  in  the  consolidated  statement  of  financial  position,  but  their 
remeasurements is not recognized in the consolidated statement of other comprehensive income (loss).

Other short-term benefits

An  accrued  expense  is  recorded  for  the  amount  the  Company  expects  to  pay  its  eligible  employees  in 
relation  to  services  rendered  during  the  reporting  period  (actual  legal  or  implicit  obligation  to  make  to 
these payments on a short-term basis).

l)

Leases

The  Company  assesses  whether  a  contract  is  or  contains  a  lease,  at  inception  of  the  contract.  The 
Company  recognizes  a  right-of-use  asset  and  a  corresponding  lease  liability  with  respect  to  all  lease 
arrangements in which it is the lessee, except for short-term leases (defined as leases with a lease term of 
12 months or less) and leases of low value assets (such as tablets and personal computers, small items of 
office  furniture  and  telephones).  For  these  leases,  the  Company  recognizes  the  lease  payments  as  an 
operating  expense  on  a  straight-line  basis  over  the  term  of  the  lease  unless  another  systematic  basis  is 
more representative of the time pattern in which economic benefits from the leased assets are consumed.

The lease liability is initially measured at the present value of the lease payments that are not paid at the 
commencement  date,  discounted  by  using  the  rate  implicit  in  the  lease.  If  this  rate  cannot  be  readily 
determined,  the  Company  uses  its  incremental  borrowing  rate.  Lease  payments  included  in  the 
measurement of the lease liability comprise:

•

•

•

•

fixed  lease  payments  (including  in-substance  fixed  payments),  less  any  lease  incentives 
receivable;

variable lease payments that depend on an index or rate, initially measured using the index or 
rate at the commencement date;

the amount expected to be payable by the lessee under residual value guarantees;

the exercise price of purchase options, if the lessee is reasonably certain to exercise the options; 
and

F-25

•

payment  of  penalties  for  terminating  the  lease,  if  the  lease  term  reflects  the  exercise  of  an 
option to terminate the lease.

The lease liability is included in the financial liabilities in the consolidated statement of financial position 
and is subsequently measured by increasing the carrying amount to reflect interest on the lease liability 
(using the effective interest method) and by reducing the carrying amount to reflect the lease payments 
made.

The  right-of-use  assets  comprise  the  initial  measurement  of  the  corresponding  lease  liability,  lease 
payments  made  at  or  before  the  commencement  day,  less  any  lease  incentives  received  and  any  initial 
direct  costs.  They  are  subsequently  measured  at  cost  less  accumulated  depreciation  and  impairment 
losses.

Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the 
site  on  which  it  is  located  or  restore  the  underlying  asset  to  the  condition  required  by  the  terms  and 
conditions of the lease, a provision is recognized and measured under IAS 37. To the extent that the costs 
relate to a right-of-use asset, the costs are included in the related right-of-use asset, unless those costs are 
incurred to produce inventories.

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying 
asset.  If  a  lease  transfers  ownership  of  the  underlying  asset  or  the  cost  of  the  right-of-use  asset  reflects 
that the Company expects to exercise a purchase option, the related right-of-use asset is depreciated over 
the useful life of the underlying asset. The depreciation starts at the commencement date of the lease.

The right-of-use assets are included in the property and equipment line item in the consolidated statement 
of financial position.

The Company applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any 
identified impairment loss.

m)

Provisions and contingent liabilities 

In  the  course  of  its  business,  the  Company  could  be  exposed  to  certain  risks  and  litigations,  notably  in 
relation to contractual arrangements. Provisions are recognized when the Company has a present legal or 
constructive obligation as a result of past events, it is probable that the Company is subject to a release of 
outflow representatives of economic benefits to settle the obligation and a reliable estimate of the amount 
of the obligation can be made. Management of the Company estimates the probability and the expected 
amount  of  a  cash  outflow  associated  with  risks,  together  with  the  other  information  to  be  provided  on 
possible  liabilities.  Where  the  Company  expects  a  provision  to  be  reimbursed,  for  example  under  an 
insurance contract, the reimbursement is recognized as a separate asset but only when the reimbursement 
is certain. 

In addition, the Company may assess a potential obligation towards a third party resulting from events the 
existence  of  which  will  only  be  confirmed  by  the  occurrence,  or  not,  of  one  or  more  events.  uncertain 
futures which are not totally under the control of the Company; or an obligation to a third party for which 
it  is  not  probable  or  certain  that  it  will  result  in  an  outflow  of  resources  without  at  least  equivalent 
consideration  expected  from  the  latter.  These  elements  are  mentioned  in  note  18  of  the  group's 
consolidated financial statements as contingent liabilities.

n)

Capital

Ordinary shares are classified in shareholders’ equity. Costs associated with the issuance of new shares 
are directly accounted for in shareholders’ equity in diminution of issuance premium. 

F-26

The Company’s own shares bought in the context of a brokering/liquidity agreement are presented as a 
reduction in shareholders’ equity until their cancellation, their reissuance or their disposal. 

o)

Share-based compensation

Since  its  inception,  the  Company  has  established  several  plans  for  compensation  paid  in  equity 
instruments  in  the  form  of  free  shares  (“Attributions  gratuites  d’actions,”  or  “AGA”),  free  preferred 
shares  convertible  into  ordinary  shares  (“Attributions  gratuites  d’actions  de  préférence  convertibles  en 
actions  ordinaires,”  or  “AGAP”),  free  performance  shares  (“Attributions  gratuites  d’actions  de 
performance,”  or  “AGA  Perf”),  share  subscription  warrants  (“Bons  de  souscription  d’actions,”  or 
“BSA”),  redeemable  share  subscription  warrants  (“Bons  de  Souscription  et/ou  d’Acquisition  d’Actions 
Remboursables,” or “BSAAR”), granted to its employees, executives, members of the Executive Board 
and scientific consultants. 

Pursuant to IFRS 2—Share-based Payment, these awards are measured at their fair value on the date of 
grant.  The  fair  value  is  calculated  with  the  most  relevant  formula  regarding  the  conditions  and  the 
settlement of each plan. 

For  share-based  compensation  granted  to  employees,  executives,  members  of  the  Executive  Board  and 
scientific consultants, the Company uses the Black-Scholes and Monte Carlo approach pricing models to 
determine  the  fair  value  of  the  share-based  compensation.  For  scientific  consultants  providing  similar 
services,  as  the  Company  cannot  estimate  reliably  the  fair  value  of  the  goods  or  services  received,  it 
measures the value of share-based compensation and the corresponding increase in equity, indirectly, by 
reference to the fair value of the equity instruments granted also using the Black-Scholes option pricing 
model. The fair value of free shares included in the model is determined using the value of the shares at 
the time of their distribution. 

In calculating the fair value of share-based compensation, the Company also considers the vesting period 
and the employee turnover weighted average probability as described in Note 11. Other assumptions used 
are also detailed in Note 11. 

The Company recognizes the fair value of these awards as a share-based compensation expense over the 
period in which the related services are received with a corresponding increase in shareholders’ equity. 
Share-based compensation is recognized using the straight-line method. The share compensation expense 
is based on awards ultimately expected to vest and is reduced by expected forfeitures. 

p)

Revenue

Revenue from collaboration and license agreements

To  date,  the  Company’s  revenue  results  primarily  from  payments  received  in  relation  to  research, 
collaboration and licensing agreements signed with pharmaceutical companies. These contracts generally 
provide for components such as: 

•

•

non-refundable upfront payments upon signature;

payments for the exercise of the option to acquire licenses of drug candidates;

• milestones payments triggered following stages of development (scientific results obtained by 

the Company or by the partner, obtaining regulatory marketing approvals);

•

•

payments related to the Company’s R&D activities;

payments  triggered  by  the  start  of  the  commercialization  of  products  resulting  from 
development  work  or  by  crossing  cumulative  thresholds  of  product  sales,  as  well  as  the 
allocation of royalties on future sales of products or a sharing of profits on sales.

F-27

Under  collaboration  and  license  agreements,  the  Company  may  promise  its  partners  licenses  on 
intellectual property, as well as research and development services. According to IFRS 15, the Company 
has to determine if the promises included in the contract are distinct (therefore recognized separately as 
revenue) or if they have to be combined as a single performance obligation.We conclude that the license 
is not distinct from the research and development services when the research and development services 
involve  the  Company's  own  expertise,  so  that  the  customer  cannot  benefit  from  the  license  alone  or  in 
combination with services provided by third parties, or when the intellectual property is at such a stage of 
development  that  the  research  and  development  work  significantly  modifies  the  initial  purpose  of  the 
license.

When  promises  in  a  collaboration  and  license  agreement  are  considered  as  a  single  performance 
obligation, the Company has to determine if the combined performance obligation is satisfied over time or 
at  point  in  time.  If  the  combined  performance  obligation  is  satisfied  over  time,  revenue  recognition  is 
based  on  the  percentage  of  completion  of  the  costs  to  be  incurred.  Non-refundable  initial  payments  are 
deferred and recognized as revenue during the period the Company is engaged to deliver services to the 
customer on the basis of the corresponding costs.

When  promises  in  a  collaboration  and  license  agreement  are  considered  as  separate  performance 
obligations,  revenue  is  allocated  to  each  obligation  proportionally  to  its  transaction  price,  which 
corresponds  to  a  price  each  performance  obligation  would  have  been  sold  in  the  context  of  a  separate 
transaction.

In accordance with IFRS 15, variable considerations cannot be included in the estimated transaction price 
as long as it not highly probable that the related revenue will not reversed in the future. According to the 
level of uncertainty relating to the results of preclinical and clinical trials and the decisions relating to the 
regulatory approvals, variable considerations depending on these events are excluded from the transaction 
price as long as the trigger event is not highly probable. When the trigger event occurs, the corresponding 
milestone is added to the transaction price. Such adjustments are recorded on a cumulative catch-up basis, 
which would affect revenues and net income (loss) in the period of adjustment. 

Revenues based on  royalties, completion of commercialization steps or co-sharing profit from sales are 
recognized when the corresponding sales of products are carried out by the partner. 

When a collaboration contract grants a partner an option to acquire a licensed intellectual property (“IP”), 
the  Company  determines  the  date  of  the  transfer  of  control  over  the  licensed  IP.  Depending  on  the 
Company analysis, revenue related to the option fee will be recognized (i) when control over the licensed 
IP  transfers  (payment  related  to  the  exercise  of  the  option  being  therefore  considered  as  a  variable 
consideration), or, (ii) deferred until the exercise of the option or its expiration period. 

When an agreement only promises development services, the Company will recognize the related revenue 
when the costs are incurred. 

Up-front and milestones payments and fees are recorded as deferred revenue upon receipt or when due, 
and  may  require  deferral  of  revenue  recognition  to  a  future  period  until  the  Company  performs  its 
obligations  under  these  arrangements.  Amounts  due  by  the  Company  in  relation  to  cost-sharing  are 
recorded as collaboration liability. Amounts payable to the Company are recorded as accounts receivable 
when the Company’s right to consideration is unconditional. 

See Note 13 for accounting description of significant agreements.

Government financing for research expenditures

Research tax credit

The research tax credit (Crédit d’Impôt Recherche) (the “Research Tax Credit” or “CIR”) granted by the 
French  tax  authorities  in  order  to  encourage  Companies  to  conduct  technical  and  scientific  research. 
Companies that can justify that these expenses meet the required criteria receive such grants in the form 
of  a  refundable  tax  credit  that  can  be  used  for  the  payment  of  taxes  due  for  the  period  in  which  the 
expense  was  incurred  and  for  the  next  three  years.  These  grants  are  presented  under  other  income,  in 
“government  financing  for  research  expenditures”  line  item  in  the  consolidated  statements  of  income 
(loss), as soon as these eligible expenses were conducted.

The Company has benefited from a Research Tax Credit since its inception. 

The  reimbursements  are  made  under  the  European  Community  tax  rules  for  small  and  medium  sized 
enterprises  (“SME”)  in  compliance  with  the  applicable  regulations  in  effect.  Only  companies  that  meet 
the definition of SME according to European Union criteria are eligible for early reimbursement of their 
CIR. Management ensured that the Company was a SME according to European Union criteria and can 
therefore benefit from this early reimbursement until as of December 31, 2019. As of December 31, 2019 
and December 31, 2023, the Company no longer met the eligibility criteria for this status (criteria not met 
after year-end analysis). Thus, the CIR for the years 2019, 2020 and 2023 represent a receivable against 
the French Treasury which will in principle be offset against the French corporate income tax due by the 
company with respect to the three following years. The remaining portion of tax credit not being offset 
upon expiry of such a period may then be refunded to the Company. The research tax credit relating to 
2019 financial year was reimbursed by the French Treasury in February 2024. 

For the 2021 and 2022 financial year, the Company met again  the definition of an SME according to the 
criteria of the European Union and therefore benefit for early repayment of the CIR in 2022 and 2023 in 
respect of the 2021 and 2022 tax years respectively.

The CIR is presented under other income, in “government financing for research expenditures” line item 
in the consolidated statements of income (loss) as it meets the definition of government grant as defined 
in IAS 20 Accounting for government grants and disclosure of government assistance. 

Subsidies

Government grants are recognized when there is a reasonable assurance that: 

•

•

The Company will comply with the conditions attached to the grants; and that 

The grants will be received.

A government grant that becomes receivable as compensation for expenses or losses already incurred, or 
for the purpose of providing immediate financial support to the Company with no future related costs, is 
recognized as other income of the period in which it becomes receivable. 

Government grants to subsidize capital expenditures are presented in the statement of financial position as 
deferred income and are recognized as income on a straight line basis over the useful life of those assets 
that have been financed through the grants. 

A non-repayable loan from the government is treated as a government grant when there is a reasonable 
assurance  that  the  Company  will  meet  the  terms  for  non-repayment  of  the  loan.  When  there  is  no  such 
assurance, the loan is recorded as a liability under borrowings.

Deferred  income  tax  is  provided  in  full,  using  the  liability  method,  on  temporary  differences  arising 
between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Main 
temporary  differences  are  generally  associated  with  the  depreciation  of  property  and  equipment, 
provisions for pension benefits and tax losses carried forward and also with the deferred tax liabilities / 
assets generated by the application of IFRS 15. Currently enacted tax rates are used in the determination 
of deferred income tax. 

Deferred  tax  assets  are  recognized  to  the  extent  that  it  is  probable  that  future  taxable  profit  will  be 
available  against  which  the  temporary  differences  can  be  utilized.  Due  to  Company’s  early  stage  of 
development, it is not probable that future taxable profit will be available against which the unused tax 
losses can be utilized. As a consequence, deferred tax assets are recognized up to deferred tax liabilities. 

s)

Earnings (loss) per share

In accordance with IAS 33 Earnings per share, basic income (loss) per share is calculated by dividing the 
income (loss) attributable to equity holders of the Group by the weighted average number of outstanding 
shares for the period.

Diluted income (loss) per share is measured by dividing the income (loss) attributable to holders of equity 
and dilutive instruments by the weighted average number of outstanding shares and dilutive instruments 
for the period. 

If in the calculation of diluted income (loss) per share, instruments giving deferred rights to capital such 
as warrants generates an antidilutive effect, then these instruments are not taken into account. 

t)

Other comprehensive income

Items  of  income  and  expenses  for  the  period  that  are  recognized  directly  in  equity  are  presented  under 
“other comprehensive income.” The items mainly include :

•

Foreign currency translation gain (loss); and

• Actuarial gains and (losses) related to defined benefit obligations.

u)

Segment information

For internal reporting purposes, and in order to comply with IFRS 8 Operating segments, the Company 
performed  an  analysis  of  operating  segments.  Following  this  analysis,  the  Company  considers  that  it 
operates within a single operating segment being the R&D of pharmaceutical products in order to market 
them in the future. All R&D activities of the Company are located in France. Key decision makers (the 
Leadership Team of the Company) monitor the Company’s performance based on the cash consumption 
of  its  activities.  For  these  reasons,  the  Management  of  the  Group  considers  it  not  appropriate  to  set  up 
separate business segments in its internal reporting. 

In  addition,  Lumoxiti  sales  were  historically  considered  insignificant  in  relation  to  the  consolidated 
financial statements taken as a whole and are now included in the income statement under "net income 
from  discontinued  operations"  following  the  signature  of  the  termination  and  transition  contract  with 
AstraZeneca in 2021 (see notes 1.a , 2.v and 17). 

v)

Non-current assets held for sale and discontinued operations

A discontinued operation is a component of an entity that either has been disposed of, or that is classified 
as  held  for  sale.  It  must  either:  represent  a  major  separate  line  of  business  or  geographical  area  of 
operations; be part of a single coordinated disposal plan; or be a subsidiary acquired exclusively with a 
view to resale. Intercompany transactions between continuing and discontinued operations are eliminated 

F-30

against discontinuing operations. Non-current assets and disposal groups are classified as assets held for 
sale if their carrying amount is to be recovered principally through a sale transaction rather than through 
continuing use. This condition is regarded as met only when the sale is highly probable and the asset (or 
disposal  group)  is  available  for  immediate  sale  in  its  present  condition.  They  are  stated  at  the  lower  of 
carrying amount and fair value less costs to sell with any resulting impairment recognized. Assets related 
to discontinued operations and assets of disposal group held for sale are not depreciated. The prior-year 
consolidated balance sheet is not restated.

Further  to  the  decision  to  terminate  the  Lumoxiti  Agreement  and  termination  notice  sent  in  December 
2020, a termination and transition agreement was discussed and executed, effective as of June 30, 2021 
terminating  the  Lumoxiti  Agreement  as  well  as  Lumoxiti  related  agreements  (including  the  supply 
agreement,  the  quality  agreement  and  other  related  agreements)  and  transferring  of  the  U.S.  marketing 
authorization  and  distribution  rights  of  Lumoxiti  back  to  AstraZeneca.  Consecutively,  the  activities 
related to Lumoxiti are presented as a discontinued operation as of October 1, 2021.

Consequently, in accordance with IFRS5 "non-current assets held for sale and discontinued operations", 
the Lumoxiti operations are presented in the consolidated statement of income (loss) and the notes to the 
consolidated financial statements as a discontinued operation for the 2021 financial year. As a reminder, 
the  2019  and  2020  comparatives  have  been  restated  compared  to  previous  publications  (where 
applicable), in accordance with the same standard.

w)

Critical accounting estimates and assumptions

The  preparation  of  the  consolidated  financial  statements  under  IFRS  requires  management  to  make 
estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, income and 
expenses  during  the  reporting  period.  The  Company  bases  estimates  and  assumptions  on  historical 
experience  when  available  and  on  various  factors  that  it  believes  to  be  reasonable  under  the 
circumstances. The Company’s actual results may differ from these estimates under different assumptions 
or conditions.

These estimates and judgments involve mainly:

•

•

the  accounting  for  collaboration  and  licensing  agreements:  the  revenue  results  primarily 
from  payments  based  on  several  components  (e.g.,  upfront  payments,  milestone  payments) 
received  in  relation  to  research,  collaboration  and  licensing  agreements  signed  with 
pharmaceutical  or  other  companies.  When  the  Company  is  committed  to  perform  R&D 
services, revenue is spread over the period the Company is engaged to deliver these services, 
more  particularly  on  the  basis  of  the  Company’s  inputs  to  the  satisfaction  of  a  performance 
obligation relative to the total expected inputs to the satisfaction of that performance obligation. 
Milestone  payments  are  dependent  upon  the  achievement  of  certain  scientific,  regulatory,  or 
commercial milestones. These variable payments are recognized when the triggering event has 
occurred,  there  are  no  further  contingencies  or  services  to  be  provided  with  respect  to  that 
event,  and  the  counterparty  has  no  right  to  refund  of  the  payment.  The  changes  in  estimate 
regarding the completion of the works and the variable consideration relating to the contracts 
signed with customers are described in Note 13. As of December 31, 2023, given the significant 
progress of the work to be performed (98.1%) and the level of budget consumption, the impact 
of accounting estimates is no longer a determining factor in the calculation of revenue related to 
the monalizumab agreement.

the  estimate  of  the  recoverable  amount  of  the  acquired  and  under  progress  licenses: 
impairment  tests  are  performed  on  a  yearly  basis  for  the  intangible  assets  which  are  not 
amortized  (such  as  intangible  assets  in  progress).  Amortizable  intangible  assets  are  tested  for 
impairment when there is an indicator of impairment. Impairment tests involve comparing the 

F-31

recoverable amount of the licenses to their net book value. The recoverable amount of an asset 
is the higher of its fair value less costs to sell and its value in use. If the carrying amount of any 
asset is below its recoverable amount, an impairment loss is recognized to reduce the carrying 
amount to the recoverable amount. The main assumptions used for the impairment test include 
(a) the amount of cash flows that are set on the basis of the development and commercialization 
plans and budgets approved by Management, (b) assumptions related to the achievement of the 
clinical trials and the launch of the commercialization, (c) the discount rate, (d) assumptions on 
risk related to the development and (e) for the commercialization, selling price and volume of 
sales, Any change in these assumptions could lead to the recognition of an impairment charge 
that could have a significant impact on the Company’s consolidated financial statements. As of 
December  31,  2022,  given  the  Company's  decision  in  December  2022  to  discontinue  the 
development of avdoralimab in the indication of bullous pemphigoid supporting the recoverable 
amount  of  the  asset  as  of  December  31,  2021  and  June  30,  2022,  the  rights  related  to  the 
intangible asset have been fully impaired for the net carrying amount of the intangible asset, of 
€41,000 thousand , without using the historical assumptions described above (see note 6). As a 
result,  the  Company  considers  that  there  are  no  longer  any  critical  estimates  in  line  with 
intangible  assets  in  2022.  Without  any  new  event  to  be  considered  since  then,  there  are 
therefore  no  longer  any  critical  assumptions  that  could  call  into  question  the  recoverable 
amount of the asset. 

3)

Management of financial risks and fair value

The  principal  financial  instruments  held  by  the  Company  are  cash,  cash  equivalents  and  marketable 
securities. The purpose of  holding these instruments is to finance the ongoing business activities of  the 
Company. It is not the Company’s policy to invest in financial instruments for speculative purposes. The 
Company does not utilize derivatives.

The principal risks to which the Company is exposed are liquidity risk, foreign currency exchange risk, 
interest rate risk and credit risk.

Liquidity risk

The Company’s cash management is performed by the Finance department, in charge of monitoring the 
day-to-day  financing  and  the  short-term  forecast  and  enabling  the  Company  to  face  its  financial 
commitments by maintaining an amount of available cash consistent with the maturities of its liabilities. 
As  of  December  31,  2023,  cash,  cash  equivalents  and  short-term  investments  were  €92,456  thousand, 
which represents more than a year of cash consumption.

The company's assets are fairly split between top-rated banks (S&P A+ rating).

The  main  characteristics  of  the  financial  instruments  owned  by  the  Company  (including  liquidity)  are 
presented in Note 4.

Foreign currency exchange risk

The Company is exposed to foreign exchange risk inherent in certain subcontracting activities relating to 
its  operations  in  the  United  States,  which  have  been  invoiced  in  U.S.  dollars.  The  Company  does  not 
currently have recurring revenues in euros, dollars or in any other currency. 

The revenue denominated in U.S. dollars has represented approximately 78%, 92% and 29%  of revenue 
in the years ended December 31, 2021, 2022 and 2023, respectively. Payments in U.S dollars represented 
approximately  50%,  50%,  and  43%  of  the  payments  in  the  years  ended  December  31,  2021,  2022  and 
2023, respectively. In order to cover this risk, the Company kept in U.S. dollars a part of the consideration 

F-32

received from AstraZeneca in June 2015, January 2019 and December 2020. The Company entirely kept 
the U.S dollars portion of the proceeds received from our Global Offering in October 2019.

The  Company’s  foreign  exchange  policy  does  not  include  the  use  of  hedging  instruments  in  its  current 
operations.

Interest rate risk

The  Company  has  very  low  exposure  to  interest  rate  risk.  Such  exposure  primarily  involves  money 
market  funds  and  time  deposit  accounts.  Changes  in  interest  rates  have  a  direct  impact  on  the  rate  of 
return  on  these  investments  and  the  cash  flows  generated.  The  Company  has  no  credit  facilities.  The 
repayment flows of the borrowings subscribed in 2017  and the two State Guaranteed Loans obtained in 
2021 and extended in 2022, are not subject to interest rate risk.

Credit risk

The  credit  risk  related  to  the  Company’s  cash  equivalents,  short-term  investments  and  non-current 
financial assets is not significant in light of the quality of the issuers. The Company deemed that none of 
the instruments in its portfolio are exposed to credit risk.

Fair value

The  fair  value  of  financial  instruments  traded  on  an  active  market  is  based  on  the  market  rate  as  of 
December 31, 2023. The market prices used for the financial assets owned by the Company are the bid 
prices in effect on the market as of the valuation date.

Cash  and  cash  equivalents  are  mainly  composed  of  current  bank  accounts,  interest-bearing  accounts, 
fixed-term  accounts  and  mutual  funds  units  (with  short-term  maturities)  held  with  various  banking 
institutions. 

Other non-current financial assets generally include a guarantee of capital at the maturity date (which is 
always longer than  one year). These instruments are defined by the Company as financial assets at fair 
value through profit or loss and classified as non-current due to their maturity.

As  of  December  31,  2021,  2022  and  2023  the  amount  of  cash,  cash  equivalents  and  financials  assets 
denominated in U.S. dollars amounted respectively to €47,164 thousand , €34,735 thousand and €20,798 
thousand

(1) In accordance with the principles described in Note 2.q, the research tax credit (Crédit d’Impôt Recherche or “CIR”) is recognized as other 
operating income in the year to which the eligible research expenditure relates. The amount of €9,800 thousand recognized in non-current 
receivables corresponds to the CIR for the 2023 tax year following the fact that the Company no longer met the eligibility criteria for the 
SME status as of December 31, 2023. Thus, the CIR for the 2023 represented a non-current receivable which will in principle be offset 
against  the  French  corporate  income  tax  due  by  the  Company  with  respect  to  the  three  following  years,  or  refunded  if  necessary  upon 
expiry of such a period. The amount of CIR recognized as current receivables as of December 31, 2023 comprises the research tax credit 
for the 2019 and 2020 tax years, for which the three years period has expired as of December 31, 2023. The CIR for 2019 was reimbursed 
in February 2024 for an amount of €16,737 thousands. Repayment of the 2020 CIR is expected in 2024 in the amount of €13,018 thousand 
euros. As a reminder, the Company has already benefited from the reimbursement of the CIR for the 2021 tax year during 2022 for an 
amount  of  €10,302  thousand  euros  and  of  the  CIR  for  the  2022  tax  year  during  2023  for  an  amount  of  €9,167  thousand  euros.  These 
amounts were received by the Company on November 16, 2022 and July 21, 2023 respectively.

(2) As  of  December  31  2023  and  December  31,  2022,  the  prepaid  expenses  includes  amounts  of  €1,005  thousand  and  €1,256  thousand, 
respectively, relating to the guarantee fees in line with the two State Guaranteed Loans from Société Générale and BNP Paribas. Following 
the  extension  of  these  two  loans  repayment  for  an  additional  period,  the  full  amount  of  the  guarantee  fee  over  the  additional  five-year 
period  has  been  recognized  as  an  operating  expense  in  2022.  As  of  December  31,  2023,  an  adjustment  is  made  through  the  prepaid 
accounts to reflect the fact that the expenses are related to the fiscal year (see note 9). 

(3) As  of  December  31,  2023,  the  amount  is  mainly  comprised  of  invoice  of  €15,000  thousand  issued  in  December  2023  following  the 
exercise of the license option by Sanofi. This amount was collected by the Company in January 2024.As a reminder, as of December 31, 
2022, the amount is entirely comprised of the receivables from AstraZeneca for an amount of €1,775 thousand and  €1,303 thousand in 
line  with  the  performance  of  research  and  development  services  under  the  monalizumab  and  IPH5201  collaboration  agreements, 
respectively. 

Trade receivables and others have payment terms of less than one year. No valuation allowance was 
recognized on trade receivables and others as the credit risk of each of debtors was considered as not 
significant.

(1) This amount relates to an additional consideration paid to Orega Biotech in January 2022 following the arbitration decision rendered in 
December  2021  relating  to  the  joint  ownership  of  certain  patents  relating  to  IPH5201.  This  additional  payment  is  fully  amortized  as  of 
December 31, 2021.

(2) As  of  December  31,  2021,  the  amount  included  the  amortization  of  rights  relating  to  monalizumab  (€1,942  thousand)  and  IPH5201 
(€368 thousand). As of December 31, 2022, this amount included the amortization of rights relating to monalizumab (€1,604 thousand) 
and IPH5201 (€587 thousand). As of December 31, 2023, this amount includes the amortization of rights relating to monalizumab (€1,138 
thousand) and IPH5201 (€2,000 thousand). 

(3) This amount corresponds to the additional payment made to Orega Biotech in October 2022 for the rights relating to IPH5201, following 
the  amendment  to  the  collaboration  and  license  option  agreement  IPH5201  concluded  with  AstraZeneca  in  October  2018  and  the 
announcement  by  the  Company  on  June  3,  2022,  of  the  progression  of  IPH5201  towards  a  Phase  2  study  in  lung  cancers  of  which  the 
Company will be a sponsor.

(4) Following the Company's decision in December 2022 to stop the development of avdoralimab in bullous pemphigoid ("BP")  indication in 
inflammation, only indication supporting the recoverable amount of the asset as of December 31, 2021 (as well that as of June 30, 2022), 
the  rights  relating  to  the  intangible  asset  have  been  fully  impaired  for  their  net  book  value  on  the  date  of  the  decision,  i.e. 
€41,000 thousand  (see below "Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S').

(5) This amount corresponds to the additional payment made to Orega Biotech in July 2023 for the rights relating to IPH5201 following the 
first patient dosed in the Phase 2 MATISSE clinical trial in June 2023, in accordance to the agreement signed in 2019. This additional 
payment is fully amortized as of December 31,2023. 

Monalizumab rights under the 2014 monalizumab (NKG2A) Novo Nordisk agreement

At  the  agreement  inception,  acquired  rights  were  recorded  as  intangible  asset  for  an  amount  of 
€7,000 thousand. The Company recorded an additional consideration of €6,325 thousand in 2015 and a 
final consideration of $15,000 thousand (€13,050 thousand) due in 2018 (see Note 1.1.a).

Since their acquisition by the Company, monalizumab rights are amortized on a straight-line basis over

amortized by 2023, which is the same estimation as of December 31, 2022, as a result of the completion 
of some trials and by modifying the estimated end dates relating to certain cohorts. 

The net book values of the monalizumab rights were €416 thousand and €1,551 thousand as of December 
31, 2023 and December 31, 2022, respectively.

IPH5201 (Anti-CD39) rights acquired from Orega Biotech

On January 4, 2016, the Company and Orega Biotech entered into an exclusive licensing agreement by 
which  Orega  Biotech  granted  the  Company  full  worldwide  rights  to  its  program  of  first-in-class  anti-
CD39 checkpoint inhibitors. The undisclosed upfront payment paid by the Company to Orega Biotech has 
been  recognized  as  an  intangible  asset  in  the  consolidated  financial  statements  for  the  year  ended 
December 31, 2016. Criteria relating to the first development milestone were reached in December 2016. 
Consequently, the amount of this milestone was recognized as an intangible asset in addition to the initial 
payment, for a total of €1.8 million as of December 31, 2022. In June 2019, the Company also paid Orega 
Biotech  €7.0  million  in  relation  to  the  anti-CD39  program  as  consideration  following  the  collaboration 
and  option  agreement  signed  on  October  22,  2018  with  AstraZeneca  regarding  IPH5201.  Under  this 
agreement, the Company also paid in April and June 2020, respectively €2.5 and €0.2 million to Orega 
Biotech following the first Phase 1 dosing relating to IPH5201.

This asset was amortized on a straight-line basis since November 1, 2018 (corresponding to the effective 
beginning date of the collaboration) until the date the Company expected to fulfill its commitment (end of 
fiscal year 2020). As a reminder, these collaboration commitments have all been fulfilled. Thus, the rights 
relating to IPH5201 are fully amortized since December 31, 2020.

Orega Biotech claimed joint ownership of certain patents relating to IPH5201. the Company and Orega 
Biotech  have  resolved  these  claims  in  an  arbitration  proceeding,  which  decision  was  rendered  in 
December 2021. As a result of this decision, the Company will be required to pay a low-teen percentage 
of sub-licensing revenues received by the Company pursuant to its agreement with AstraZeneca regarding 
IPH5201 Following this arbitration decision, the Company paid in January 2022 an additional amount of 
0.4 million euros to Orega Biotech. 

The Company announced on June 3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung 
cancer, of which the Company will be a sponsor. In accordance with the amendment signed on June 1, 
2022,  the  Company  was  eligible  for  a  milestone  payment  of  $5  million  by  AstraZeneca,  received  in 
August 2022 by the Company. In October 2022, the Company therefore paid an additional €0.6 million to 
Orega Biotech.

On  June  26,  2023,  the  Company  announced  the  treatment  of  the  first  patient  in  the  Phase  2  MATISSE 
trial, conducted in collaboration with AstraZeneca and evaluating IPH5201 in early-stage lung cancer. As 
a consequence, the Company made an additional payment of €2.0 million to Orega Biotech in July 2023, 
in accordance with the agreement signed in 2019. 

The Company may also be obligated to pay Orega Biotech up to €48.2 million upon the achievement of 
development and regulatory milestones. 

Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S

At  the  agreement  inception,  an  upfront  payment  of  €40  million  for  acquired  rights  were  recorded  as 
intangible asset. As part of this agreement, an additional amount of €1.0 million was paid in October 2020 
to Novo Nordisk A / S following the launch of the first avdoralimab Phase 2 trial. As avdoralimab is still 
in  clinical  trial,  the  acquired  rights  are  classified  as  intangible  asset  in  progress.  They  were  subject  to 
annual impairment test. No impairment were recorded since inception. 

F-37

According to the agreement, the Company will pay additional payments according to the reach of specific 
steps.  As  of  December  31,  2023,  according  to  the  uncertainty  of  these  potential  future  payments,  no 
liability was recognized.

Development costs incurred by the Company are recognized as research and development expenses.

During  2022  fourth  quarter,  the  Company  was  informed  by  the  sponsor  of  the  Phase  2  clinical  trial 
evaluating  avdoralimab  in  inflammation  in  bullous  pemphigoid  ("BP")  indication  of  its  decision  to 
discontinue said trial. Consequently, the Company decided in December 2022 to stop the development of 
avdoralimab  in  bullous  pemphigoid  ("BP")    indication  in  inflammation,  only  indication  supporting  the 
recoverable amount of the asset as of December 31, 2021 (as well that as of June 30, 2022). 

Following that decision, the Company applied IAS 36 "Impairment of assets" and assessed that there was 
an indication of impairment sufficiently significant to result in the full impairment of the intangible asset. 
This  depreciation  was  recognized  with  regard  to  the  estimate  of  the  recoverable  value  of  avdoralimab's 
intangible assets, based on expected future cash flows, as of December 2022, date of the decision. Thus, 
on  decision  date  to  stop  the  development  of  avdoralimab  in  bullous  pemphigoid  ("BP")    indication  in 
inflammation, avdoralimab rights were fully written down to their net book value, i.e €41,000 thousand.

relating to the program lacutamab IPH4102 for an amount of €1,500 thousand. 

(2)  As  a  reminder,  on  August  11,  2020,  the  Company  signed  a  financing  contract  with  Bpifrance 
Financement  as  part  of  the  program  set  up  by  the  French  government  to  help  develop  a  therapeutic 
solution with a preventive or curative aim against COVID-19. This funding, for a maximum amount of € 
6.8m, consisted of (i) an advance repayable only in the event of technical and commercial success and (ii) 
a non-repayable grant. This funding should have been received in four successive installments. The first 
tranche  of  1.7  million  euros  was  paid  at  signing,  and  the  other  three  tranches  should  be  received  after 
successful completion of certain clinical milestones, particularly around Phase 2 of the FORCE trial. The 
portion relating to the repayable advance included in this first tranche amounted to €1,454 thousand as of 
December 31, 2020 (including actualization). As of December 31, 2021, this financing is considered by 
the  Company  to  be  non-refundable,  in  accordance  with  the  terms  of  the  agreement,  in  light  of  the 
technical and commercial failure of the project based on the results of the Phase 2 "Force" trial evaluating 
avdoralimab in COVID-19, published on July 6, 2021 (see note 13.2). 

(3)  On  January  5,  2022,  the  Company  announced  that  it  had  obtained  €28.7  million  in  non-dilutive 
financing  in  the  form  of  two  State  Guaranteed  Loans  from  Société  Générale  (€20.0  million)  and  BNP 
Paribas (€8.7 million). The Company received the funds related to these two loans on December 27 and 
30,  2021  respectively.  Both  loans  have  an  initial  maturity  of  one  year  with  an  option  to  extend  to  five 
years from August 2022. They are 90% guaranteed by the French government as part of the package of 
measures put in place by the French government to support companies during the COVID-19 pandemic. 
In August 2022, the Company has requested the extension of these two loans repayment for an additional 
period of five years starting in 2022 and including a one-year grace period. Consequently, the Company 
has obtained agreements from Société Générale and BNP Paribas. The effective interest rates applied to

these contracts during the additional period are 1.56% and 0.95% for Société Générale and BNP Paribas 
loans, respectively, excluding insurance and guarantee fees, with an amortization exemption for the entire 
year 2023. During this grace period, the Company will only be liable for the payment of interest and the 
guarantee fees, with amortization of the two loans starting in 2024 over a period of four years. The state 
guarantee fees amounts to €877 thousand and €379 thousand for Société Générale and BNP Paribas loans 
respectively. 

(4)  On  July  3,  2017,  the  Company  borrowed  from  the  Bank  “Société  Générale”  in  order  to  finance  the 
construction of its future headquarters. This loan amounting to a maximum of €15,200 thousand will be 
raised during the period of the construction in order to pay the supplier payments as they become due. As 
of December 31, 2018 and 2019, the loan was raised at an amount of €1,300 thousand.

The loan release period was limited to August 30, 2019. On August 30, 2019, the Company drew down 
the  remaining  portion  of  the  €15,200  thousand  loan  granted,  for  an  amount  of  €13,900  thousand.  The 
reimbursement of the capital has begun in August 30, 2019 and will proceed until August 30, 2031 (12 
years). Given the development of its portfolio and in particular the refocusing of its activities on research 
and development, the Company has for the time being suspended the project to build its new head office 
on  the  land  acquired  in  Luminy.  In  the  meantime,  the  loan  will  be  used  to  finance  several  structuring 
projects (improvement of the information system, development of a commercial platform, development of 
additional premises rented, etc.). As of December 31, 2023, the remaining capital of the loan amounted to 
€10,247  thousand.  The  Company  authorized  collateral  over  financial  “Société  Générale”  instruments 
amounting to €15,200 thousand. The security interest on the pledge financial instruments will be released 
in  accordance  with  the  following  schedule:  €4,200  thousand  in  July  2024,  €5,000  thousand  in  August 
2027 and €6,000 thousand in August 2031.

This loan bears a fixed interest rate of 2.01%. It is subject to a covenant based on the assumption that the 
total cash, cash equivalents and current and non-current financial assets are at least equal to principal as of 
financial year end.

(3)  On  March  13,  2023,  the  Company  signed  an  amendment  to  the  lease  for  the  "Le  Virage"  building, 
reducing the surface area of the leased premises. The effective date of the lease amendment is March 15, 
2023. As a result, and in accordance with IFRS 16, the impact on the consolidated balance sheet at the 
effective date of the lease amendment is as follows: write-off of a right of use (asset) of €0.5 million and a 
lease liability of €0.7 million.

French law requires payment of a lump sum retirement indemnity to employees based on years of service, 
the rights guaranteed by the collective agreements and annual compensation at retirement. Benefits do not 
vest prior  to retirement. The  Company pays for this defined benefit plan. It is calculated as the present 
value  of  estimated  future  benefits  to  be  paid,  applying  the  projected  unit  credit  method  whereby  each 
period  of  service  is  seen  as  giving  rise  to  an  additional  unit  of  benefit  entitlement,  each  unit  being 
measured  separately  to  build  up  the  final.  As  a  reminder,  in  April  2021,  the  IFRIC  (  or  "IFRS 
Interpretations Committee") sent a proposal to the IAS Board (International Accounting Standards Board) 
to change the way in which the liabilities for certain defined benefit plans are calculated. The IAS Board 
endorsed  this  position  in  June  2021.  The  impacts  of  this  change  in  valuation  method  are  taken  into 
account since 2021.

In addition, the impact of the 2023 pension reform (including the raising of the retirement age) has been 
recognized as a plan amendment within the meaning of IAS 19, recognized in the income statement and 
balance sheet with no material impact as of June 30, 2023. 

On  March  24,  2016,  the  Company  entered  into  an  internal  labor  agreement  with  the  employees 
representatives  whereby  the  Company  is  committed  to  paying  a  seniority  award  after  15  years  and  20 
years of employment. This award is paid on the anniversary date. A similar award existed for employees 
having a seniority of 10 years but was not booked due to its insignificant amount. As such, in 2016 the 
Company  recorded  a  provision  for  seniority  awards  and  a  corresponding  charge  included  in  “Personnel 
costs other than share-based payments” (see Note 14) other than payments in shares. These awards meet 
the  definition  of  other  long-term  benefits  under  IAS  19.  This  provision  is  determined  by  an  external 
actuary firm based on the assumptions disclosed hereafter and amounts to €377 thousand as of December 
31, 2023 (€366 thousand as of December 31, 2022).

The main actuarial assumptions used to evaluate retirement benefits are the following:

Economic assumptions 
Discount rate (iBoxx Corporate AA) for retirement 
Annual rate of increase in wages 
Demographical assumptions 
Type of retirement 

Annual mobility rate

Rate of contributions
Rate of wages costs
Age at retirement
Employees borned before 1st January 1968

(1) In its April 2021 Update, the IFRS IC published a final agenda decision clarifying how to calculate the 
obligation relating to certain defined benefit plans under which the retirement benefit is (i) contingent on 
the employee being employed by the entity at the time of retirement; (ii) capped at a specified number of 
years  of  service;  and  (iii)  linked  to  the  employee's  length  of  service  at  the  date  of  retirement.  In  that 
decision,  the  IFRS  IC  took  the  view  that  the  obligation  should  be  recognized  only  over  the  years  of 
service  preceding  the  date  of  retirement  in  respect  of  which  the  employee  generates  entitlement  to  the 
benefit. The application of this decision has led to a change in accounting method, the effects of which 
should  be  taken  into  account  retrospectively  in  accordance  with  IAS  8.  However,  as  the  Company 
considers the impact of this change of method on defined benefit obligation and the income statement to 
be insignificant, these impacts have not been restated for years prior to January 1, 2021. The effects of 
this change of method are therefore taken into account retrospectively as of January 1, 2021 in respect of 
2020's and prior years defined benefit obligation. The adjustment at that date corresponds to a reduction 
in  the  2020  commitments  in  the  amount  of  €1,054  thousand.  This  reversal  has  been  offset  against 
previous reserves and retained earnings. 

There is no asset covering the defined benefit obligations.

An increase/decrease of +/- 25 basis point of the discount rate would result in a decrease/increase of the 
total benefit obligation of €62 thousand.

The  amounts  recognized  as  an  expense  linked  to  defined  contributions  plans  amounted    to  €1,434 
thousand, €1,432 thousand and €1,283 thousand in the years ended December 31, 2021, 2022 and 2023, 
respectively.

11) Share capital and share based payments

a)

Share capital

The Company manages its capital to ensure that the Company will be able to continue as a going concern 
while maximizing the return to shareholders through the optimization of the debt and equity balance. 

The  Company  has  never  declared  or  paid  any  dividends  on  its  ordinary  shares.  The  Company  does  not 
anticipate paying cash dividends on its equity securities in the foreseeable future and intend to retain all 
available funds and any future earnings for use in the operation and expansion of its business, given our 
state of development.

As  of  December  31,  2023,  the  Company’s  share  capital  amounted  to  €4,043,732.85  divided  into  (i) 
80,860,563 ordinary shares, each with a nominal value of €0.05, (ii) 6,509 “2016” free preferred shares, 
each  with  a  nominal  value  of  €0.05  and  (iii)  7,581  “2017”  free  preferred  shares,  each  with  a  nominal 
value of €0.05, respectively fully paid up.

Share  capital  does  not  include  BSAs,  BSAAR,AGAs  and  AGAPs  that  have  been  granted  to  certain 
investors or natural persons, both employees and non-employees of the Company, but not yet exercised. 

In October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has 
ended.  The  number  of  ordinary  shares  to  which  the  conversion  of  one  preferred  share  entitle  has  been 
determined according to the fulfillment of the performance criteria. Holders of “2016” preferred shares” 
are entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on 
the basis of the number of ordinary shares to which they are entitled if they convert their preferred shares.  

In  April  3,  2021,  the  retention  period  for  the  "2017  free  preferred  shares"  has  ended.  The  number  of 
ordinary shares to which the conversion of one preferred share entitle has been determined according to 
the fulfillment of the performance criteria. According to these same performance criteria, the Executive 
Board of April 7, 2021 noted that the "2017 preferred shares" did not give right to any ordinary shares. 
The “2017 preferred shares” will not be redeemed by the Company and will remain incorporated into the 
capital,  unless  subsequently  decided  by  the  Executive  Board.  As  the  conversion  is  void,  the  "2017 
preferred shares" no longer give the right to vote at our general meetings, nor to receive dividends.

The table below presents the historical changes in the share capital of the Company as of December 31, 
2021, 2022 and 2023, respectively:

The fair value of granted free shares is based on the closing price of the Company’s share at grant date, 
reduced  when  necessary  by  an  estimated  turn-over  rate.  This  estimated  fair  value  is  recognized  as 
operating expenses on a straight-line basis over the vesting period.

Free performance shares 2018 (AGA Perf Employees 2018-1 and AGA Perf Management 2018-1)

Free  performance  shares  granted  in  2018  are  subject  to  share  price  conditions  and  a  vesting  kicker 
triggered by the performance of an internal condition, which is the success of certain clinical trials. 

The fair value of these free performance shares is based on a third-party valuation report. The valuation 
method used to estimate the fair value of these free performance shares is presented below: 

•

Estimation of the expectation of gain associated with internal and share price conditions, made 
on the basis of a CAPM model of the share price using a Monte Carlo approach; 

• Adjustment of the estimation by applying expected turnover rates.

Changes  in  internal  conditions  are  taken  into  account  in  the  revision  of  the  estimated  number  of  free 
performance shares expected to vest during the vesting period. 

On January 3, 2022, the Executive Board determined the achievement of the performance conditions and 
the  final  vesting  of  the  free  performance  shares  2018  as  of  November  20,  2021.  The  underlying 
performance conditions were thus achieved at 55%, noting on November 20, 2021 the final acquisition of 
103,125 “AGA Perf Employees 2018-1” as well as 110,000 “AGA Perf Management 2018-1”.

Expenses  were  €(232)  thousand  (income)  for  the  financial  year  ended  December  31,  2021.  These 
instruments were definitively acquired during the 2021 financial year. Consequently, no expense relating 
to these plans was recognized during the financial year ended December 31, 2022 and 2023. 

AGA 2017-1 Management (New Members)

Expenses  were  €71  thousand  for  the  financial  year  ended  December  31,  2021.  These  instruments  were

Free performance shares 2019 (AGA Perf Employees 2019-1 / AGA Perf Management 2019)

Free  performance  shares  granted  in  2019  are  subject  to  share  price  conditions  and  a  vesting  kicker 
triggered by the performance of an internal condition, which is Lumoxiti's market penetration rate in the 
United States. 

The fair value of these free performance shares is based on a third-party valuation report. The valuation 
method used to estimate the fair value of these free performance shares is presented below: 

•

Estimation of the expectation of gain associated with internal and share price conditions, made 
on the basis of a CAPM model of the share price using a Monte Carlo approach; 

• Adjustment of the estimation by applying expected turnover rates. 

On November 7, 2022, the Executive Board determined the achievement of the performance conditions 
and  the  final  vesting  of  the  2019  free  performance  shares  as  of  November  4,  2022.  The  underlying 
performance conditions were thus achieved at 50%. Consequently, on November 7, 2022, the Executive 
Board  carried  out  the  definitive  acquisition  of  171,550  free  performance  shares  under  the  "AGA  Perf 
Management 2019-1" plans.

Expenses  were  €649  thousand,  €(181)  thousand  (income)  for  the  financial  years  ended  December  31, 
2021, 2022 and respectively. Income relating to the 2022 financial year is explained by the review of the 
performance  conditions  during  the  2022  financial  year  with  regard  to  the  definitive  achievement  of  the 
vesting.  These  instruments  were  definitively  acquired  during  the  2022  financial  year.  Consequently, no 
expense relating to these plans was recognized during the financial year ended December 31,2023. 

Free performance shares 2020 (AGA Perf Employees 2020-1 / AGA Perf Management 2020)

Free  performance  shares  granted  in  2020  are  subject  to  share  price  conditions  and  two  vesting  kickers 
triggered by the performance of internal conditions, which are :

• A commercial break-even point for Lumoxiti in the U.S. reached at the end of fiscal year 2023 
(this criterion will not be met given the return of the commercial rights notified to AstraZeneca in 
December 2020).

• Revenue from collaborative and licensing agreements accrued between the attribution and 

definitive acquisition date (excluding payment by AstraZeneca for the first patient in Phase 3 for 
monalizumab), reaching $100 million.

The fair value of these free performance shares is based on a third-party valuation report. The valuation 
method used to estimate the fair value of these free performance shares is presented below: 

•

Estimation of the expectation of gain associated with internal and share price conditions, made 
on the basis of a CAPM model of the share price using a Monte Carlo approach;

• Adjustment of the estimation by applying expected turnover rates. 

On January 2, 2024, the Executive Board determined the achievement of the performance conditions and 
the  final  vesting  of  the  2020  free  performance  shares  as  of  December  31,  2023.  The  underlying 
performance conditions were thus achieved at 20%. Consequently, on December 31, 2023, the Executive 
Board  carried  out  the  definitive  acquisition  of  85,230  free  performance  shares  under  the  "AGA  Perf 
Employees  2020-1"  plans  and  130,000  free  performance  shares  under  the  "AGA  Perf  Management

BSAAR

BSAAR  are  securities  whose  subscription  price  and  exercise  price  are  fixed  at  their  fair  value  as 
determined by an expert. The BSAAR subscription therefore represents an investment on the part of the 
beneficiary. At the end of the exercise period, if they have not been exercised, the BSAAR becomes void. 
The Company benefits from a clause called «forcing» making it possible to encourage holders to exercise 
their redeemable equity warrants when the market price exceeds the exercise price and reaches a threshold 
defined  in  the  BSAAR  issuance  agreement.  The  Company  may,  then,  subject  to  a  time  period  for 
notifying  holders  that  will  permit  them  to  exercise  the  BSAAR,  decide  to  reimburse  the  warrants  not 
exercised at a unit price equal to the BSAAR acquisition price paid by its holder.

Details of BSAAR

BSAAR.  The  methodology  used  to  estimate  the  fair  value  of  the  BSAAR  is  similar  to  the  one  used  to 
estimate the fair value of the BSA, except for the following:

Expected  Term.  Unlike  the  BSA,  the  Company  does  not  have  sufficient  historical  experience  for  the 
BSAAR. Consequently, the expected term used for the valuation of the fair value is the legal maturity of 
the instrument (10 years).

No share-based payment compensation expense was recognized relating to the BSAAR since the amount 
paid by the beneficiaries is equal to the fair value.

a)

Revenue recognition related to monalizumab AstraZeneca agreements and amendments

The  Company  identified  the  following  promises  under  the  monalizumab  AstraZeneca  agreements  and 
amendments: (1) a non-exclusive license related to monalizumab restricted to two applications, with an 
option for an exclusive license related to monalizumab including all applications, (2) the performance of 
certain initial studies related to Phases 1/2 trials, and participation in certain studies of Phases 1/2 trials 
and Phase 3 clinical trials through a co-financing.

The  Company  considered  the  license  has  a  standalone  functionality  and  is  capable  of  being  distinct. 
However the Company determined that the license is not distinct from the performance of initial studies 
and participation to Phase 3 clinical trials because they increased the utility of the licensed IP. Thus, the 
licensed IP, the performance of initial studies and participation to Phase 3 clinical trials are combined into 
a single performance obligation.

This performance obligation was considered as satisfied over time as AstraZeneca controls the licensed IP 
which is being enhanced during the agreement. The revenue is recognized over time, based on the input 
method (costs incurred). As a result, the Company recognizes the price of the transaction as a revenue on 
the basis of the progress of studies that the Company has undertaken to carry out under the agreement. 

F-68

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Progression is assessed following to actual costs incurred relative to the total budgeted costs to fulfill the 
obligation.

The transaction price was initially estimated to the initial payment of $250,000 thousand, less the amounts 
that  the  Company  expected  to  pay  to  AstraZeneca  for  co-financing  Phase  1/2  clinical  studies.  The 
additional  payment  of  $100,000  thousand  triggered  by  AstraZeneca’s  exercise  of  the  exclusivity  option 
was  treated  as  a  change  in  the  price  estimate  of  the  transaction.  In  addition,  the  amendment  of  the 
contract, which modified the scope and budget of the studies to be carried out by the Company as well as 
the arrangements for sharing the cost of the other studies, led to a revision of the degree of progress and 
the price of the transaction. Thus, the exercise of the option and the amendment of the contract resulted in 
the recognition of a favourable cumulative adjustment of €38,321 thousand in revenue for the year ended 
December 31, 2019.

The additional payment of $50,000 thousand triggered by the dosing of the first patient in the Phase 3 trial 
evaluating monalizumab was treated in full as a collaboration commitment ("collaboration liability" in the 
consolidated  balance  sheet)  in  view  to  the  commitment  linked  to  the  contract  for  the  Phase  1/2  (co-
financing)  and  Phase  3  studies  (amendment  signed  in  September  2020).  Consequently,  this  additional 
payment has no impact on the transaction price. 

In addition to these amounts, AstraZeneca made an additional payment of $50.0 million (€47.7 million) in 
June  2022  and  triggered  by  the  treatment  of  the  first  patient  in  a  second  Phase  3  trial  “PACIFIC-9” 
evaluating  monalizumab  in  April  2022.  This  additional  payment  has  been  treated  as  an  increase  of  the 
collaboration commitment ("collaboration liabilities" in the consolidated statements of financial position)  
for an amount of $36.0 million (€34.3 million) in connection to the Phase 3 study co-funding commitment 
made by the Company and notified to AstraZeneca in July 2019. The remaining amount of $14.0 million 
(€13.4  million)  has  been  treated  as  an  increase  of  the  transaction  price,  recognized  in  the  income 
statement in line with the progress of the Phase 1/2 studies. 

The subsequent milestones and potential royalty payments are excluded from the transaction price due to 
the uncertainties of clinical trials results.

The  Company  used  the  most  likely  amount  to  determine  variable  consideration.  Variable  consideration 
for cost-sharing payments related to certain studies of Phases 1/2 trials and Phase 3 clinical trials when 
applicable are included in the transaction price.

As  a  reminder,  the  expected  payments  to  AstraZeneca  are  classified  as  collaboration  liability  in  the 
consolidated  statement  of  financial  position.  Quarterly  invoices  received  from  AstraZeneca  reduce  the 
collaboration liability and have no impact on the consolidated statement of income.

(1)  As  a  reminder,  the  increase  in  deferred  revenue  relating  to  monalizumab  agreement  between 
December 31, 2021 and December 31, 2022 is explained by the additional payment of €47,687 thousand 
($50,000 thousand)  made by AstraZeneca in June 2022 and triggered by the launch of the “PACIFIC-9” 
Phase  3  trial  on  April  28,  2022.  This  increase  has  led  to  a  simultaneous  increase  in  collaboration 
commitment ("collaboration liability"- see below) of €34,335 thousand ($36,000 thousand) in accordance 
with  the  Company’s  July  2019  option  concerning  the  co-financing  of  Phase  3  trials  in  the  field  of 
collaboration.

€4,677 thousand as of December 31, 2022 which resulted from the entire recognition in revenue of the 
$5.0 million (€4.7 million) milestone payment received from AstraZeneca following the signature on June

1, 2022 of an amendment to the initial contract signed in October 2018. This amendment sets the terms of 
the  collaboration  following  AstraZeneca’s  decision  to  advance  IPH5201  to  a  Phase  2  study.  The 
Company will conduct the study. Both parties will share the external cost related to the study and incurred 
by the Company and AstraZeneca will provide products necessary to conduct the clinical trial. 

c)

Revenue recognition related to collaboration and license agreement signed with Sanofi in 2016

Revenues under the collaboration and license agreement signed with Sanofi in 2016 amounted to €2,000 
thousand  for  the  year  ended  December  31,  2023  as  compared  to  €4,000  thousand  for  the  year  ended 
December 31, 2022. The Company announced that, in June 2023, the first patient was dosed  in a Sanofi-
sponsored  Phase  1/2  clinical  trial  evaluating  IPH6401/SAR'514  in  relapsed  or  refractory  Multiple 
Myeloma. As provided by the licensing agreement signed in 2016, Sanofi made a milestone payment of 
€2.0 million, fully recognized in revenue since June 2023. This amount was received by the Company on 
July 21, 2023. As a reminder, the revenue recognized in 2022 resulted from Sanofi's decision to advance 
IPH6401/SAR'514  towards  regulatory  preclinical  studies  for  a  new  investigational  drug.  This  decision 
triggered a milestone payment of €3.0 million fully recognized in revenue. This amount was received by 
the Company on September 9, 2022. 

d)  Revenue recognition related to Sanofi research collaboration and licensing agreement (2022)

On January 25, 2023, the Company announced the expiration of the waiting period under the Hart-Scott-
Rodino (HSR) Antitrust Improvements Act of 1976 and the effectiveness of the licensing agreement as of 
January  24,  2023.  Consequently,  under  the  terms  of  such  agreement,  the  Company  received  an  upfront 
payment  of  €25,000  thousand  in  March  2023,  including  €18,500  thousand  for  the  exclusive  license, 
€1,500  thousand  for  the  research  work  and  €5,000  thousand  for  the  two  additional  targets  options.  On 
December  19,  2023,  the  Company  announced  that  Sanofi  had  exercised  an  option  for  a one  of  the  two 
preclinical  molecules.  This  option  exercise  also  resulted  in  a  milestone  payment  of  €15,000  thousand, 
including €13,300 thousand in respect of the exclusive license, which was fully recognized in income as 
of  December  31,  2023,  and  €1,700  thousand  in  respect  of  research  work  to  be  carried  out  by  the 
Company.  The  Company  considers  that  the  licenses  granted  constitute  a  right  to  use  the  intellectual 
property  granted  exclusively  to  Sanofi  from  the  effective  date  of  the  agreement.  As  such,  all  upfront 
payments relating to the licenses granted have been recognized in the income statement representing an 
amount  of  €31,800  thousand,  including  €18,500  thousand  relating  to  the  B7-H3  license  and  €13,300 
thousand following the option exercised. 

e)  Revenue recognition related to Takeda licensing agreement (2023)

On April 3, 2023, the Company announced that it has entered into an exclusive license agreement with 
Takeda under which Innate grants Takeda exclusive worldwide rights to research and develop antibody 
drug conjugates (ADC) using a panel of selected Innate antibodies against an undisclosed target, with a 
primary focus in Celiac disease. Takeda will be responsible for the future development, manufacture and 
commercialization  of  any  potential  products  developed  using  the  licensed  antibodies.  As  such,  the 
Company  considers  that  the  license  granted  is  a  right  to  use  the  intellectual  property,  which  is  granted 
fully and perpetually to Takeda. The agreement does not stipulate that Innate's activities will significantly 
affect the intellectual property granted during the life of the agreement. Consequently, the $5.0 million (or 
€4.6  million)  initial  payment,  received  by  the  Company  in  May  2023,  was  fully  recognized  in  revenue 
since June 30, 2023. This amount was received by the Company in May 2023.

For the financial years ended December 31, 2022 and 2023, the foreign exchange gains and losses mainly 
result from the variance of the exchange rate between the Euro and the U.S. dollar on U.S. dollars 
denominated cash and cash equivalent and financial assets accounts.

Unrealized losses on financial assets relate to unquoted instruments, the fair value of which is determined 
using level 2 measurements.

16) Income Tax

Due  to  the  Company’s  early  stage  of  development,  it  is  not  probable  that  future  taxable  profit  will  be 
available against which the unused tax losses can be utilized. As a consequence, deferred tax assets are 
recognized up to deferred tax liabilities.

Temporary differences mainly result from leases, provision for defined benefit obligation and tax losses 
carryforwards.

As of December 31, 2023, the accumulated tax losses carryforwards of Innate Pharma SA were €483,570 
thousand with no expiration date (€392,633 and €466,153 thousand as of December 31, 2021 and 2022). 
At  December  31,  2023,  the  amount  of  losses  carried  forward  by  Innate  Pharma  S.A.  at  December  31, 
2022 has been adjusted downwards by €277.0 thousand to take account of the impact of the tax audit.

As of December 31, 2023, the accumulated tax losses carryforwards of Innate Pharma Inc. was €15,181 
thousand,  or  $16,775  thousand,  (€11,955  thousand,  or  $16,081  thousand  and  €14,198  thousand,  or 
$16,446 thousand as of December 31, 2021 and 2022, respectively), with a 20-year period expiration.

21) Events after the reporting date

• On January 4, 2024, the Company announced that the U.S. Food and Drug Administration (FDA) has 
lifted the partial clinical hold placed on the lacutamab IND. On October 5, the Company announced 
that  the  lacutamab  IND  has  been  placed  on  partial  clinical  hold  by  FDA  following  a  recent  patient 
death  in  the  TELLOMAK  study.  The  death  of  a  patient  affected  by  Sézary  Syndrome  was  initially 
considered  due  to  hemophagocytic  lymphohistiocytosis  (HLH),  a  rare  hematologic  disorder.  The 
FDA  decision  to  lift  the  partial  clinical  hold  is  based  on  the  FDA  review  of  the  fatal  case  which 
Innate,  together  with  a  steering  committee  of  independent  experts,  determined  to  be  related  to 
aggressive disease progression and lacutamab unrelated.

• On January 4, 2024, the company announced that it has strengthened the Company’s leadership and 
corporate  governance  with  the  appointment  of  two  new  Executive  Board  members.  Arvind  Sood, 
Executive  Vice  President  (EVP),  President  of  US  Operations,  Dr  Sonia  Quaratino,  EVP,  Chief 
Medical  Officer  are  thus  joining  Hervé  Brailly,  interim  Chief  Executive  Officer  and  Yannis  Morel, 
EVP, Chief Operating Officer.

• On March, 6, the Company announced the first patient was dosing in its Phase 1/2 multicenter trial 
(NCT06088654), investigating the safety and tolerability of IPH6501 in patients with Relapsed and/or 
Refractory CD20-expressing B-cell Non-Hodgkin’s Lymphoma (NHL). IPH6501 is Innate’s first-in-
class CD20-targeting tetraspecific ANKET® (Antibody-based NK cell Engager Therapeutics) that co-
engages CD20 as a target antigen on malignant B cells and three receptors on NK cells.
