PIO NEERING A 
TR ANSFO RMATIONAL 
AP PROACH FOR 
CANCER PATIENTS

D E A R   S H A R E H O L D E R S :

2021  MARKED  A  PRODUCTIVE  YEAR  FOR  IOVANCE.  We 
made significant strides in advancing our mission to be the 
global leader in innovating, developing and delivering tumor 
infiltrating lymphocyte (TIL) therapy for patients with cancer.

First  and 
foremost,  we  prioritized  work  to  address 
feedback  from  the  U.S.  Food  and  Drug  Administration 
(FDA)  regarding  the  potency  assays  that will  support  our 
planned biologics license application (BLA) submission for 
lifileucel,  as  well  as  regulatory  plans  in  other  indications. 
We  worked  diligently  throughout  2021  on  developing 
and  validating  our  potency  assays,  while  engaging  in 
discussions  with  the  FDA  to  facilitate  alignment.  As  a 
result of these efforts, we received positive feedback from 
the  FDA  in  April  2022  on  both  our  potency  assay  matrix 
and  our  proprietary  cell  co-culture  assay  included  in  the 
potency assay matrix. 

In  parallel,  we  continued  to  build  upon  the  strength  of 
clinical data for Iovance TIL therapy in multiple solid tumor 
types and treatment settings, with 2021 marking our busiest 
year yet for clinical data presentations. We presented data 
for 118 patients across five indications in four solid tumor 
types at multiple medical meetings, including meetings of 
the  American  Association  for  Cancer  Research  (AACR), 
American  Society  of  Clinical  Oncology  (ASCO),  and 
Society  for  Immunotherapy  of  Cancer  (SITC),  and  the 
Journal  of  Clinical  Oncology  published  a  manuscript 
with  our  clinical  data  for  Cohort  2  in  the  C-144-01  study 
of  lifileucel  in  metastatic  melanoma.  We  believe  that  this 
growing  set  of  clinical  data  continue  to  demonstrate  the 
potential power of Iovance TIL therapy to become the next 
paradigm-shifting treatment regimen for solid tumors.

Looking  toward  what  is  next  in  TIL  therapy  innovations, 
we  continued  to  broaden  our  pipeline.  We 
laid  the 
groundwork  to  initiate  our  first  clinical  study  of  a  gene-
edited  TIL  product  candidate  in  2022,  while  maintaining 
robust  activity  across  our  preclinical  next  generation  TIL 
and peripheral blood lymphocyte pipeline. 

In addition, last year we completed initial construction and 
opened  the  Iovance  Cell Therapy  Center  (iCTC),  in  Navy 
Yard  Philadelphia.  We  made  significant  progress  in  our 
internal manufacturing capabilities at the iCTC throughout 
the  year.  We  also  grew  our  organization  by  33%  and 
executed robust plans to support commercial launch and 
pipeline expansion.

Iovance TIL Therapy (Lifileucel) in Metastatic Melanoma

At  ASCO  2021,  we  presented  long-term  clinical  data  for 
one-time treatment with lifileucel in metastatic melanoma. 
Follow  up  data  as  assessed  by  investigators  from  Cohort 
2  (n=66)  in  the  C-144-01  study  of  lifileucel  in  metastatic 
melanoma  demonstrated  an  overall  response  rate  (ORR) 
of 36.4% (4.5% complete response rate and 31.8% partial 

response rate) and median duration of response was not 
reached at 33.1 months of median study follow up. These 
Cohort  2  data  continue  to  demonstrate  the  durability  of 
one-time treatment with lifileucel in metastatic melanoma 
patients  after  anti-PD-1  therapy.  We  expect  to  report 
clinical  data  from  the  pivotal  melanoma  Cohort  4  as 
assessed  by  an  independent  review  committee  (IRC)  in 
2022 in connection with the BLA submission.

immune  checkpoint 

lines  of  treatment,  promising 
Looking  toward  earlier 
results for TIL therapy in combination with pembrolizumab 
in 
inhibitor  (ICI)  naïve  melanoma 
patients  were  presented  at  SITC  2021.  We  shared 
updated data in April 2022 from the combination cohort of 
lifileucel and pembrolizumab in ICI naïve patients. Cohort 
1A  in  the  IOV-COM-202  study  (n=12)  demonstrated  an 
ORR  of  67%.  All  responders  (eight  of  12  patients)  had  a 
confirmed  objective  response  per  RECIST  1.1,  including 
three complete responses and five partial responses. Six 
of the eight responders had ongoing response at the time 
of the last data cut, and five responders had a duration of 
response of more than one year.

The  FDA  granted  Fast  Track  Designation  for  lifileucel  in 
combination  with  pembrolizumab  for  the  treatment  of 
ICI  naïve  (frontline)  metastatic  melanoma  based  on  the 
unmet  medical  need  and  potential  advantages  for  this 
combination over available care. We plan to open a Phase 
III study for lifileucel in combination with pembrolizumab for 
the treatment of ICI naïve frontline metastatic melanoma in 
late 2022. 

TIL Therapy in Non-Small Cell Lung Cancer

Beyond  melanoma,  we  are  excited  about  our  proof-of-
concept data for TIL therapy LN-145 in non-small cell lung 
cancer (NSCLC).

NSCLC  patients  continue  to  have  an  unmet  need  for 
new  treatment  options.  We  were  very  encouraged  by 
the  observed  responses  for  LN-145  in  heavily  pretreated 
NSCLC patients who received one or more prior systemic 
therapies,  including  anti-PD-1  therapy.  This  data  set  was 
an  important  signal  for  TIL  therapy  in  NSCLC.  We  are 
currently enrolling patients who are earlier in their disease 
but  have  received  prior  anti-PD-1  therapy  in  our  ongoing 
IOV-LUN-202 study at more than 30 sites.

Additional TIL Therapy Combinations with Immune 
Checkpoint Inhibitors (ICIs)

In addition to frontline melanoma, our oral presentation at 
SITC 2021 highlighted TIL therapy plus pembrolizumab as 
an early treatment option for patients with cervical cancer 
and  head  and  neck  squamous  cell  carcinoma  (HNSCC). 
Initial results from 14 patients treated with a combination 
of  TIL  therapy  plus  pembrolizumab  in  Cohort  3  of  our 
C-145-04  cervical  cancer  study  demonstrated  an  ORR 
of 57.1% at a median follow up of 7.6 months. In HNSCC, 
we presented updated results for TIL in combination with 
pembrolizumab  from  Cohort  2A  of  our  IOV-COM-202 
study.  Results  demonstrated  a  38.9%  ORR  at  a  median 
study  follow  up  of  7.8  months  in  a  cohort  of  18  patients 
with HNSCC who are naïve to therapy with ICIs. 

TIL Manufacturing and Iovance Cell Therapy Center (iCTC)

important  milestones  at  the  iCTC,  our 
We  achieved  several 
136,000 square foot cell therapy manufacturing facility, which is 
expected to become one of the largest cell therapy manufacturing 
facilities  in  the  world.  In  the  third  quarter  of  2021,  the  iCTC 
successfully manufactured and delivered its first clinical batch of 
LN-145 for a patient in our IOV-COM-202 trial, representing our first 
internally  manufactured  TIL  product.  We  continue  to  supply  the 
IOV-COM-202  trial,  and  other  ongoing  trials,  with  both  internally 
manufactured and externally manufactured TIL products.

More than 500 patients have received Iovance TIL products and 
our  manufacturing  success  rate  remains  above  90%.  The  iCTC 
is  expected  to  support  commercial  supply  upon  FDA  approval 
of  lifileucel,  and  to  meet  demand  for  thousands  of  people  with 
cancer  each  year.  In  parallel  with  clinical  manufacturing,  we  are 
on track in our efforts to prepare the iCTC for the BLA submission 
and commercial manufacturing upon the potential BLA approval.

To  further  optimize  manufacturing,  we  are 
investigating  our 
proprietary  Generation  3  (Gen  3)  process  to  manufacture  TIL 
in  just  16  days.  Cohorts  of  metastatic  melanoma  patients  in  the  
the  
IOV-COM-202  study  as  well  as  NSCLC  patients 
IOV-LUN-202 study are being treated with TIL manufactured by the 
Gen 3  process.  We  also  continue  to  manufacture  our  peripheral 
blood  lymphocyte  therapy,  IOV-2001,  and  our  PD-1  selected  TIL 
therapy, LN-145-S1, for our ongoing clinical trials.

Toward TIL Commercialization

The  Iovance  team  has  made  steady  progress  in  our  commercial 
launch  preparations  to  support  the  availability  of  TIL  therapy  for 
patients  at  launch.  Our  launch  priorities  include  the  on-boarding 
of  our  authorized  treatment  centers  (ATCs),  payer  engagement, 
and  related  operational  readiness  activities.  We  aim  to  on-board 
at least 40 ATCs for launch, with a longer-term goal to have enough 
sites so that most patients in the U.S. can be within a few hours’ 
drive to an ATC offering lifileucel TIL therapy. The planned timing 
and  execution  of  key  onboarding  and  training  is  aligned  to  BLA-
related milestones to ensure just-in-time training and readiness at 
our ATCs.  Our  core  commercial  team  has  built  the  foundation  to 
scale rapidly and efficiently. 

Reimbursement  is  also  an  important  focus  for  us  as  we  look  to 
support  broad  patient  access  at  launch.  We  continue  to  engage 
payers  and  CMS  as  we  prepare  for  commercialization.  Notably, 
Medicare  expanded  its  key  diagnosis-related  group  DRG-018  in 
2021  to  include  chimeric  antigen  receptor  T  cell  therapies  and 
other  immunotherapies  including  lifileucel.  This  is  an  important 
milestone achievement because upon approval hospitals will have 
more appropriate payment for Medicare beneficiaries. 

We  are  also  pleased  with  the  progress  of  our  IovanceCares™ 
program, which remains on track for launch. Our goal is to deliver a 
best-in-class cell ordering and patient support system that assists 
the patients, physicians and ATCs at every step of the process. 

Expanding Our Pipeline

company  using  its  pioneering  gene-editing  platform  to  develop 
potentially  life-saving  cell  and  gene  therapies,  to  inactivate  the 
gene  coding  for  the  PD-1  protein.  By  removal  of  this  important 
barrier for T cells to attack cancer, IOV-4001 has the potential to 
become an optimized, next generation TIL therapy for several solid 
tumor cancers. We received FDA IND allowance to proceed with 
a clinical study of IOV-4001 in metastatic melanoma and NSCLC 
patients in March 2022 and expect to initiate the study in 2022.

IOV-4001 represents a significant evolution of our TIL platform. The 
ability to inactivate and insert multiple genes within a TIL product 
provides  a  significant  opportunity  to  deliver  a  product  with  the 
potential  for  superior  efficacy  for  multiple  solid  tumor  types.  We 
look  forward  to  bringing  IOV-4001  and  other  gene-edited  TIL 
products into the clinic, building upon our expertise in centralized 
TIL manufacturing.

We  continue  to  advance  additional  research  and  preclinical 
studies of next generation TIL therapies and related technologies, 
including a novel IL-2 analog (IOV-3001). Approaches to increase 
TIL  potency  using  CD39/69  double  negative  TIL  therapies  and 
other novel technologies are also in preclinical development. 

Organizational Growth

In  2021,  our  employee  population  grew  by  32.4%.  We  now  have 
more than 390 employees at Iovance who have, on average, more 
than four years of cell therapy experience. We believe the breadth 
and  depth  of  talent within  our  organization  during  this  important 
time  of  growth  is  a  testament  to  the  potential  of  our  Iovance TIL 
therapy  in  solid  tumors  and  our  ability  to  maintain  leadership 
within the field.

We  have  a  diverse  Board  of  Directors  and  management  team: 
women  account  for  over  55%  of  the  total  number  of  positions 
considered  manager-level  or  above,  and  52%  of  our  total 
employees.  Racially  diverse  employees  (those  self-identifying  as 
Black or African American, Hispanic or Latino, Asian, or being two 
or more races) make up approximately 47% of our global workforce 
and  approximately  44%  of  management.  We  are  committed  to 
building and supporting a diverse workforce with a deep bench of 
talent and a strong corporate culture. We also plan to produce our 
first Corporate Responsibility Report, to summarize and report our 
performance and progress in terms of environmental, social, and 
governance criteria.

We remain committed to our vision of pioneering a transformational 
approach  to  cure  cancer  by  harnessing  the  human  immune 
system’s  ability  to  recognize  and  destroy  diverse  cancer  cells  in 
each patient. Our team made significant progress in 2021, and we 
look  forward  to  taking  even  greater  strides  in 2022 with  our  first 
planned BLA submission. Thank you to our dedicated employees, 
clinical  investigators,  collaboration  partners,  shareholders,  and 
most importantly, the patients with cancer and their families who 
motivate us every single day.

Overview 

PART I 

We are a clinical-stage biopharmaceutical company pioneering a transformational approach to cure cancer by harnessing the 

human immune system’s ability to recognize and destroy diverse cancer cells in each patient. TIL therapy is an autologous, polyclonal 
cell therapy platform technology that was originally developed by the National Cancer Institute, or NCI, which conducted initial 
clinical trials of this therapy in diseases such as metastatic melanoma and cervical cancer. Our mission is to be the global leader in 
innovating, developing and delivering TIL therapies for patients with cancer. We have developed a new, shorter TIL manufacturing 
process known as Gen 2, which yields a cryopreserved TIL product. This centralized, proprietary, and scalable manufacturing method 
is being investigated in multiple indications. Our lead product candidates include lifileucel for metastatic melanoma and metastatic 
cervical cancer, as well as LN-145 for metastatic non-small cell lung cancer, or NSCLC. In addition, we are investigating the 
effectiveness and safety of combinations of TIL therapy with immune checkpoint inhibitors, or ICIs, in metastatic melanoma, cervical 
cancer, NSCLC, and head and neck squamous cell carcinoma, or HNSCC. We are investigating peripheral blood lymphocyte, or PBL, 
therapy for patients with relapsed or refractory chronic lymphocytic leukemia, or CLL, and small lymphocytic lymphoma, or SLL, 
through our sponsored trials. We are developing first-in-class genetically edited TIL products based on the inactivation of genes that 
encode immune checkpoint proteins and other proteins, as well as the insertion of genes that encode immunomodulatory proteins. We 
are also developing an alternative interleukin-2, or IL-2, co-therapy for use with TIL therapies. Finally, we are investigating the 
potential for TIL therapy in other oncology indications and treatment settings through academic collaborations with leading cancer 
research centers.

Our current product candidate pipeline is summarized in the figure below: 

TIL Monotherapy in Metastatic Solid Tumor Cancers 

We have investigated TIL monotherapy in metastatic melanoma, cervical cancer, NSCLC and HNSCC. We are conducting a 

Phase 2 clinical trial, C-144-01, of our lead TIL product candidate, lifileucel, for the treatment of metastatic melanoma. This 
multicenter pivotal trial enrolled melanoma patients with disease progression following treatment with at least one systemic therapy, 
including a PD-1 inhibitor and, if BRAF mutated, a BRAF inhibitor, or a combination of BRAF and MEK inhibitors. Cohort 4 of the 
C-144-01 clinical trial is a single-arm cohort intended to support the submission of a Biologics License Application, or BLA, to the 
FDA for lifileucel. Cohorts 2 and 4 of the C-144-01 trial use our Gen 2 manufacturing process. We completed and closed enrollment 
of patients into Cohort 2 of the C-144-01 trial in 2018. Results from Cohort 2 of the C-144-01 clinical trial were initially reported at 
the American Society of Clinical Oncology annual meeting, or ASCO, in June 2019 and most recently updated at ASCO in June 2021. 
As of the data extract in April 2021, in 66 patients with metastatic melanoma in Cohort 2, treatment with lifileucel resulted in an 
objective response rate, or ORR, of 36%, as assessed by investigator, with 3 complete responses and 21 partial responses. The disease 
control rate, or DCR, was 80.3%. Median duration of response, or DOR, in Cohort 2 had not been reached after 33.1 months of 
median study follow up. Results from Cohort 2 presented at ASCO in June 2021 also suggest that early intervention with lifileucel at 
the time of initial progression on anti-PD-1 therapy may maximize benefit. Patients in Cohort 2 were heavily pretreated and had a 
mean of 3.3 prior therapies. We have previously reported durable responses across a wide age range of metastatic melanoma patients, 
among those who have received prior anti-CTLA-4 and BRAF targeted treatments, regardless of BRAF mutation status, and in 
patients with PD-L1 high and low status. The adverse event profile was generally consistent with the underlying advanced disease and 
the profile of the lymphodepletion and IL-2 regimens. In addition, detailed Cohort 2 data was published in the Journal of Clinical 
Oncology in May 2021.  

Pivotal Cohort 4 of the C-144-01 trial was enrolled to evaluate ORR as read out by an Independent Review Committee, or IRC, 

as the primary endpoint based on our interpretation of discussions with the FDA as part of an End of Phase 2, or EOP2, meeting held 
with the FDA in the third quarter of 2018. In October 2018, based on the data provided to the FDA during the EOP2 meeting, we 
announced that lifileucel had received a Regenerative Medicines Advanced Therapy, or RMAT, designation from the FDA. 
Enrollment in Cohort 4 of the C-144-01 trial commenced in March 2019 and patient dosing was completed in January 2020. A total of 
87 patients were dosed with Gen 2 product released for Cohort 4. In May 2020, we disclosed initial results from Cohort 4 for 68 
patients with two radiological assessments, as determined by investigator.

Previously, we reported the submission of additional potency assay data to the FDA, and at the same time, we also announced 
that we had reached agreement with the FDA on the minimum duration of follow up for Cohort 4 to support our BLA submission for 
lifileucel in the treatment of metastatic melanoma. In May 2021, we announced that we had received regulatory feedback from the 
FDA regarding our potency assays for lifileucel. Following FDA feedback, we have continued our ongoing work developing and 
validating our potency assays and have engaged in discussions with the FDA during the second half of 2021. Our BLA submission for 
lifileucel in metastatic melanoma is expected to occur during the first half of 2022. In connection with this BLA submission, the IRC 
is expected to independently assess responses for Cohort 4 patients through the data cut date, which must be completed prior to BLA 
submission or disclosure of IRC-read data. 

We are also conducting a Phase 2 clinical trial, C-145-04, which is a multicenter pivotal trial to assess the safety and efficacy of 

our lead product candidate lifileucel for the treatment of patients with recurrent, metastatic, or persistent cervical cancer. In February 
2019, lifileucel received Fast Track designation from the FDA for development in the treatment of cervical cancer with disease 
progression on or after chemotherapy. In March 2019, the protocol for this trial was amended to modify the primary endpoint of ORR 
to be determined by IRC. In May 2019, lifileucel received Breakthrough Therapy Designation, or BTD, from the FDA for 
development in the treatment of cervical cancer. Results from the C-145-04 clinical trial were reported at ASCO in June 2019. In 
27 patients with metastatic cervical cancer, treatment with lifileucel resulted in an ORR of 44%. At the time of the study data cut, 
there were 3 complete responses and 9 partial responses. The DCR was 85%. Patients were heavily pretreated and had a mean of 2.4 
prior therapies. The median DOR had not been reached. The adverse event profile was generally consistent with the underlying 
advanced disease and the profile of the lymphodepletion and IL-2 regimens. In November 2019, we amended the C-145-04 trial to 
collect additional data on early-line patients as well as late-line patients by adding additional cohorts, in anticipation of a changing 
landscape in this indication, including Cohort 2 for patients that had previously received chemotherapy and anti-PD-1/anti-PD-L1 
therapy. In January 2021, we announced that Cohort 2 of the C-145-04 trial had completed enrollment and that data from this cohort 
may be supportive of registration because of the expected changing landscape of care for cervical cancer patients. For example, 
because of recent regulatory approvals for pembrolizumab, there may be a potential shift from chemotherapy in front-line cervical 
cancer followed by pembrolizumab in second-line cervical cancer to the use of pembrolizumab in combination with chemotherapy in 
first-line cervical cancer. We intend to execute our registrational strategy based on dialog and feedback from the FDA on these cohorts 
and continue to plan for a potential BLA submission for lifileucel in cervical cancer. 

In November 2020, we announced that we had finalized the protocol for our potential registrational clinical trial in NSCLC, 

IOV-LUN-202, to investigate LN-145 in patients with metastatic NSCLC, without driver mutations, who previously received a single 
line of approved systemic therapy of combined checkpoint inhibitor and chemotherapy. The IOV-LUN-202 clinical trial includes three 
cohorts. Cohorts 1 and 3 of the IOV-LUN-202 clinical trial are enrolling patients with a PD-L1 TPS of less than one percent at the 
time they started front-line therapy, and Cohort 2 will enroll patients with a PD-L1 TPS of greater than or equal to one percent at the 
time they started front-line therapy. Cohort 3 will also explore manufacturing TIL extracted from core biopsies using our third-
generation, or Gen 3, manufacturing process. In June 2021, we reported that the first patient was dosed in the IOV-LUN-202 clinical 
trial. We intend to continue to enroll patients in the IOV-LUN-202 clinical trial throughout 2022. We are engaged in regulatory 
discussions with the FDA on IOV-LUN-202 and intend to incorporate FDA feedback to optimize this clinical trial to support further 
registration in NSCLC. 

In June 2021, we reported initial data for LN-145 in Cohort 3B of our IOV-COM-202 clinical trial in metastatic NSCLC. IOV-

COM-202 is a Phase 2, multicenter trial that is composed of seven cohorts. Cohort 3B of IOV-COM-202 enrolled patients with 
metastatic NSCLC that had progressed on prior ICI therapy, including patients with oncogene-driven tumors who received prior 
tyrosine kinase inhibitor therapy. Patients were treated with LN-145 monotherapy. We reported results from Cohort 3B of the IOV-
COM-202 trial in June 2021. The ORR was 21.4% for the 28 patients in the analysis population, including one complete response and 
five partial responses, and the DCR was 64.3%, including two responders with PD-L1 negative tumors, and 3 responders who had 
primary refractory disease to checkpoint inhibitors. The treatment emergent adverse event, or TEAE, profile was consistent with the 
underlying disease and known adverse event profiles of non-myeloablative lymphodepletion and IL-2. All patients treated in Cohort 
3B of the IOV-COM-202 trial received prior anti-PD-1/L1 therapy and all six responding patients also received prior chemotherapy. 
Historically, ORRs of approximately 20% were reported with ICIs as second-line therapy in ICI-naïve patients who progressed on 
front-line chemotherapy. We also provided an update on Cohort 3B at the Society for Immunotherapy in Cancer Annual Meeting, or 
SITC, in November 2021. As of the data extract in August 2021, following one-time treatment with LN-145 monotherapy, the ORR 
remained at 21.4% for the 28 patients in the analysis population, and was 25% in the efficacy-evaluable set of 24 patients, including 
one complete response and five partial responses. One complete response and one partial response were ongoing at 20.7 months and 
3.0 months, respectively, at a median study follow up of 9.8 months.  

6 

 
 
 
 
C-145-03 is our Phase 2, multicenter trial to assess the safety and efficacy of our product candidate LN-145 for the treatment of 

patients with metastatic HNSCC. In October 2018, we reported that preliminary data for 13 patients in the C-145-03 clinical trial 
yielded an ORR of 31% with a DOR ranging from 2.8 to 7.6 months. The adverse event profile remained consistent with previous 
reports. We redesigned our C-145-03 trial to include multiple cohorts, in order to allow for dosing of TIL therapies produced by 
multiple manufacturing methods, including our Gen 2 manufacturing process, our Gen 3 manufacturing process, and our PD-1 
selected TIL manufacturing process. Our PD-1 selected TIL manufacturing process results in a product that we refer to as LN-145-S1. 
In January 2021, we announced that we will close the C-145-03 clinical trial after the trial reached its pre-specified enrollment target. 

TIL Combinations in Earlier Treatment Settings for Solid Tumors 

We are investigating the potential of our TIL therapies in earlier lines of treatment in combination with pembrolizumab or other 

ICIs in cancer patients who are naïve to anti-PD-1 therapy. ICIs are a class of immunotherapy drugs that seek to overcome one of 
cancer’s main escape mechanisms against an immune system attack. PD-1 is a checkpoint protein found on immune cells called T 
cells that normally acts as a type of “off switch” which helps prevent T cells from attacking other cells in the body. It is activated by 
binding to PD-L1, a protein found on both normal and cancerous cells, which thereby may shut down an attack by a T cell. Some 
cancer cells have large amounts of PD-L1 expressed on their surfaces, which helps them evade T cell attack.  

We are investigating the potential for our TIL therapy mechanism, together with checkpoint inhibition provided by ICIs, to 

improve response rates compared to ICIs alone in several sold tumor types, including in four cohorts in our IOV-COM-202 study in 
solid tumors as well as in one cohort in our C-145-04 clinical study in cervical cancer. In addition to its ongoing enrollment in the 
U.S., the IOV-COM-202 trial has also received regulatory approval in Canada and in certain European countries. 

In Cohort 1A of the IOV-COM-202 trial, we are enrolling advanced unresectable or metastatic melanoma patients who are 

naïve to anti-PD-1 therapy. We reported results from ongoing Cohort 1A of the IOV-COM-202 trial at ASCO in June 2021, as 
follows, from the initial seven patients. Seven patients received lifileucel in combination with pembrolizumab. Six of the seven 
patients had a confirmed objective response, with an ORR of 86%, including two complete responses, one unconfirmed complete 
response who had not yet reached the confirmatory complete response assessment, and three partial responses, with one best response 
of stable disease. The complete response rate, including the unconfirmed complete response, was 43%. The median follow up was 8.2 
months. The Cohort 1A results also demonstrated that lifileucel can be safely combined with pembrolizumab. In November 2021, we 
provided updated results from 10 patients in an oral presentation at SITC in which there was a demonstrated ORR of 60%. Six out of 
the 10 patients had a confirmed objective response, including three complete responses and three partial responses. Historically, ORRs 
of 33% and a CR rate of 6% have been reported for pembrolizumab monotherapy in metastatic melanoma. Based on these results, we 
plan to expand enrollment in this cohort in early line melanoma in 2022. 

In Cohort 2A of the IOV-COM-202 trial, we are enrolling advanced, recurrent, or metastatic HNSCC patients who are naïve to 
prior immunotherapy including anti-PD-1/anti-PD-L1 therapy. The patients receive LN-145 in combination with pembrolizumab. We 
reported results from ongoing Cohort 2A of the IOV-COM-202 trial at the SITC meeting in November 2020, as follows. As of 
October 16, 2020, nine HNSCC patients have received LN-145 plus pembrolizumab with a median duration of follow up of 8.6 
months. Four patients had a confirmed, objective response with an ORR of 44% including one complete response and three partial 
responses. Median DOR was not reached. The DCR at data cutoff was 89% in nine patients, and seven of the eight evaluable patients, 
or 87.5%, had a reduction in target lesions. The median number of prior therapies was 1.0 with 89% of the patients having received 
prior chemotherapy. Four patients were positive for Human Papilloma Virus, or HPV, three patients were HPV negative, and two 
patients had unknown HPV status. In November 2021, we provided updated results from 18 patients in an oral presentation at SITC in 
which there was a demonstrated ORR of 38.9%. Seven out of the 18 patients had an objective response, including one complete 
response, one unconfirmed complete response, four partial responses and one unconfirmed partial response. Historically, ORRs of 
17% have been reported for pembrolizumab monotherapy in patients with HNSCC. 

Our oral presentation at SITC in November 2021 also included initial results from 14 patients treated with a combination of  

TIL therapy plus pembrolizumab in Cohort 3 of our C-145-04 cervical cancer study. The ORR was 57.1%, and eight out of 14 patients 
had an objective response, including one complete response, six partial responses and one unconfirmed partial response.  Cervical 
cancer patients previously treated with standard of care systemic therapy achieve an ORR of 11%-14% with pembrolizumab 
monotherapy.

The Cohort 1A and Cohort 2A results from the IOV-COM-202 study as well as Cohort 3 from the C-145-04 study 

demonstrated that lifileucel or LN-145 can be safely combined with pembrolizumab. The TEAE profile in all Cohorts was consistent 
with the underlying advanced disease and the known adverse event profiles of pembrolizumab, lymphodepletion, and IL-2 regimens.  

Two additional cohorts, Cohort 3A and 3C in the IOV-COM-202 study, explore LN-145/ICI combination therapies in NSCLC 

patients. Cohort 3A is evaluating LN-145 in combination with pembrolizumab in patients with recurrent or metastatic NSCLC who 
have not received prior immunotherapy, including checkpoint inhibitors. Cohort 3C is investigating LN-145 therapy in combination 
with ipilimumab and nivolumab in patients with recurrent or metastatic NSCLC who have previously received one line of approved 
checkpoint inhibitor monotherapy as the only prior line of systemic therapy. 

In September 2021, we announced that our Iovance Cell Therapy Center, or the iCTC, had successfully manufactured and 

delivered its first clinical batch of LN-145 for the IOV-COM-202 trial, representing our first internally manufactured TIL product.  
We continue to supply the IOV-COM-202 trial, and other ongoing trials, with both internally manufactured and externally 
manufactured TIL products. 

Next-Generation and Genetically Modified Product Candidates 

Our clinical pipeline also includes next generation TIL product candidates and manufacturing processes, as well as a cytokine-

engrafted protein. Our TIL candidate LN-145-S1, in which TIL are selected for PD-1 expression, is being investigated in post-anti-
PD-1 melanoma in Cohort 1B of our IOV-COM-202 basket study as well as in post-anti-PD-1 HNSCC in Cohort 4 of our C-145-03 
trial.  

We are using our Gen 3 manufacturing process in Cohort 1C of the IOV-COM-202 clinical trial in melanoma and in Cohort 3 

of the IOV-LUN-202 clinical trial in NSCLC and have previously used it in the C-145-03 clinical trial in HNSCC.  

In November 2019, we announced that our Investigational New Drug, or IND, application for our PBL therapy, IOV-2001, was 
authorized by the FDA. Our sponsored clinical trial using this therapy, IOV-CLL-01, was cleared to proceed and patient dosing began 
in 2020. IOV-2001 is a non-genetically modified, polyclonal T cell product that is manufactured using a nine-day process starting 
from 50 mL of patient's blood. IOV-CLL-01 is a Phase 1/2 clinical trial evaluating the safety and efficacy of IOV-2001 in patients 
with relapsed or refractory CLL or SLL.  

In January 2020, we announced a research collaboration and exclusive worldwide licensing agreement with Cellectis S.A., or 

Cellectis, a clinical-stage biopharmaceutical company focused on developing immunotherapies based on gene-edited allogeneic 
chimeric antigen receptor modified T cells. The worldwide exclusive license enables us to use certain TALEN® technology 
addressing multiple gene targets to develop TIL that have been genetically modified to create potentially more potent cancer therapies  
for use in several cancer indications. We are nearing completion of IND-enabling studies under this agreement and expect to initiate 
our first clinical study in 2022 of a genetically modified TIL product candidate, IOV-4001, in which the gene coding for the PD-1 
protein is inactivated. Financial terms of the license include development, regulatory and sales milestone payments from us to 
Cellectis, as well as royalty payments based on net sales of TALEN-modified TIL products. In addition to IOV-4001, we are currently 
developing additional targets for genetic modification using the TALEN technology, including double-knock out programs in 
preclinical development. 

We continue to explore additional transient and permanent genetic modifications of TILs. For example, under the amended and 
restated patent license agreement we entered into in May 2021 with National Institutes of Health, or NIH, an agency of the U.S. Public 
Health Service within the Department of Health and Human Services, we license a patent family related to cytokine-tethered TILs, 
which are intended to potentially expand and activate TILs to achieve better efficacy while avoiding systemic side effects of 
cytokines. We are currently developing cytokine-tethered TIL products in preclinical studies. 

In addition, in January 2020, we obtained a license from Novartis Pharma AG, or Novartis, to develop and commercialize an 
antibody cytokine engrafted protein, which we refer to as IOV-3001. Under the agreement, we paid an upfront payment to Novartis 
and may pay milestones involved in initiation of patient dosing in various phases of clinical development for IOV-3001 and approval 
of a potential product in the U.S., EU, and Japan. We are currently conducting IND-enabling studies of this novel IL-2 analog. 
Novartis is also entitled to low-to-mid single digit percentage royalties from commercial sales of IOV-3001.

Investigator-Sponsored Trials  

Through our academic collaborators, we are also exploring the potential for TIL therapies in additional indications. As part of 

our collaboration program with The University of Texas M.D. Anderson Cancer Center, or MDACC, two Phase 2 trials were initiated 
in 2018. Both trials are sponsored by MDACC. The first trial, NCT03449108, investigates LN-145 manufactured by us, using our 
manufacturing processes, to treat patients with soft tissue sarcoma, osteosarcoma, platinum resistant ovarian cancer, and thyroid 
cancer. A second trial under the collaboration with MDACC, NCT03610490, was previously active. This trial treated patients with 
platinum resistant ovarian cancer, pancreatic and colorectal cancer with TIL manufactured by MDACC. The data obtained using this 
manufacturing process may not be representative of our data using our Gen 2 manufacturing process. We also collaborate with many 
other academic institutions using our TIL therapies.  For example, a trial in collaboration with The Ohio State University, 
NCT05176470, is expected to start recruiting in 2022, and explores the use of lifileucel in high-risk melanoma in the neoadjuvant 
setting. 

Corporate Strategy 

We aim to be the global leader in innovating, developing and delivering TIL therapy for patients with cancer. We are 
pioneering a transformational approach to cure cancer by harnessing the human immune system’s ability to recognize and destroy 
diverse cancer cells in each patient. We are committed to continuous innovation in developing TIL cell therapy, including gene-edited 
cell therapy, shorter manufacturing processes, and alternatives to IL-2 across a spectrum of tumor types including but not limited to 
melanoma, cervical cancer, NSCLC and HNSCC that may extend and improve life for patients with cancer. Key elements of our 
strategy include: 

Expedite clinical development, regulatory approval, and commercialization of our lead product candidate lifileucel for the 

treatment of metastatic melanoma as well as Iovance TIL and additional polyclonal cell therapies for cancer. 

Based on results of TIL therapy from our own clinical trials in metastatic melanoma as well as trials sponsored by the NCI, we 

are focused on expediting the development, regulatory approval and commercialization of our lead product candidate, lifileucel, for 
the treatment of patients with metastatic melanoma. We intend to file a BLA for lifileucel in metastatic melanoma in the first half of 
2022. We are also investigating TIL monotherapy as a one-time treatment for advanced cervical cancer and NSCLC patients who have 
progressed following standard of care treatments, TIL in combination with ICIs for melanoma, cervical, NSCLC and HNSCC as 
treatment in earlier disease settings, and a PBL therapy intended to address hematologic malignancies. 

Continue to expand manufacturing capacity for TIL products. 

We continue to invest in improving the process and efficiency of manufacturing our product candidates in the U.S. and Europe 

for TIL manufacturing.  

We began construction of the iCTC, our own manufacturing facility, in 2019, in Philadelphia, Pennsylvania, in order to provide 

for better margins and rapid implementation of innovative changes for TIL therapies that we may develop or commercialize. We 
intend to carefully manage our cost structure, and reduce the long-term cost of manufacturing our products, although there can be no 
assurance that we will be able to reduce our manufacturing costs to commercially attractive levels. As of the end of 2021, we have 
completed commissioning activities and the iCTC had successfully manufactured and delivered first clinical batch of LN-145 for the 
IOV-COM-202 trial, representing our first internally manufactured TIL product. 

Currently we use the iCTC as well as several contract manufacturing organizations, or CMOs, to supply our TIL-based 

products for our clinical trials under various manufacturing services agreements, or MSAs. The use of CMOs is intended to 
supplement the manufacturing capacity at the iCTC. 

In 2016, we entered into a three-year MSA and related statements of work with WuXi Advanced Therapies, Inc., or WuXi, for 
two current Good Manufacturing Practices, or cGMP, manufacturing suites to be established and operated by WuXi for us in order to 
increase our TIL manufacturing capacity in facilities with both clinical and commercial capability for two suites. We have since 
extended our MSA with WuXi until February 2022 for the first suite and December 2022 for the second suite. 

In 2017, we entered into a three-year MSA and related statements of work with PharmaCell B.V., or PharmaCell, a contract 

manufacturing services company based in the Netherlands, to manufacture our autologous cell therapy products for use in our 

9 

 
 
European clinical trials. PharmaCell was subsequently acquired by Lonza Group Ltd., or Lonza. Lonza continues to manufacture TIL 
products for our European clinical trials in its clinical and commercial facility in Geleen, the Netherlands. We have since extended our 
agreements with Lonza until April 2022. 

Also in 2017, we entered into a two-year MSA and related statements of work with Moffitt, to manufacture our autologous cell 

therapy products for use in clinical trials, which has since been extended until March 2025. Moffitt continues to manufacture TIL 
products for our clinical trials in the U.S. 

Continue to improve our TIL manufacturing processes and develop new TIL manufacturing technology to become the 

preferred provider of TIL therapy in the U.S. and the rest of the world. 

We are currently manufacturing TIL for our ongoing clinical studies at the iCTC and remain on track to provide commercial 

supply from this facility upon potential BLA approval. We believe that we are the only company in the U.S. to have a centralized, 
demonstrated, and commercially viable TIL manufacturing process. In 2018, we first utilized our Gen 2 TIL manufacturing process, 
which reduced TIL manufacturing time from 5-6 weeks to 22 days, allowing for a commercially viable product candidate. The Gen 2 
process also produces a cryopreserved TIL product for ease of administration and handling. The Gen 2 manufacturing process was 
utilized in Cohort 2 and Cohort 4 of our C-144-01 trial and has also been selected for use in most of our ongoing TIL clinical 
development program. We have included Gen 2 as the manufacturing process for registration for our discussions with the FDA and 
the anticipated BLA filing for lifileucel. Our strategy is to establish our Gen 2 process as a commercial manufacturing process for TIL 
therapies, including lifileucel. We also continue to develop and evaluate potential future TIL manufacturing processes, including our 
16-day Gen 3 process and genetically modified TIL and other next generation TIL products and processes. 

Collaborate with governmental, academic and corporate partners to improve and develop TIL and PBL therapies for new 

indications or for use in combination with other therapies, and to evaluate new manufacturing methods. 

In addition to our own research and process development efforts, we seek to collaborate with government, academic research 
institutions, and corporate partners to improve TIL manufacturing and to develop and explore TIL therapies for new indications. For 
example, we have ongoing licensing agreements and collaborations with Moffitt, MDACC, Yale University, Cellectis, Novartis, 
Melanoma Institute Australia, or MIA, and Beth-Israel Deaconess Medical Center, or BIDMC, to evaluate several new solid tumor 
and hematologic indications for TIL and PBL therapy in clinical and preclinical studies as well as, in some cases, new TIL 
manufacturing approaches. In August 2021, we extended our Cooperative Research and Development Agreement, or CRADA, with 
the NCI for another 3-year term. This collaboration with the NCI is directed at research on unmodified TIL therapy and also addresses 
HPV-associated cancers (cervical and head and neck), lung, bladder, and breast cancers. This collaboration also focuses on Strategies 
to expand TIL with less differentiated and more stem-like attributes which may result in improved persistence, functionality, and 
better anti-tumor activity. For example, in December 2021 we presented data at ESMO Immuno-oncology 2021 that demonstrated 
temporally inhibiting AKT signaling during ex vivo TIL expansion enhances cytokine production and function while increasing the 
population of less differentiated (CD39/CD69) CD8+T-Cells. A description of certain of these collaborations and related agreements 
is provided in the following sections of this Annual Report on Form 10-K. 

Iovance-Sponsored Clinical Trials 

We currently have six ongoing Phase 2 clinical studies. The ongoing studies include C-144-01, of our lead product candidate, 

lifileucel, for the treatment of metastatic melanoma; C-145-04, of our product candidate lifileucel for recurrent, metastatic or persistent 
cervical cancer; IOV-LUN-202, a potentially registration-supporting study of our product candidate LN-145 in NSCLC; IOV-COM-
202, a basket trial that will treat three cohorts of checkpoint naïve patients with TIL therapy in combination with pembrolizumab for 
metastatic melanoma, HNSCC and NSCLC, a cohort that will treat relapsed and refractory NSCLC patients with TIL monotherapy, as 
well as a cohort for NSCLC for TIL therapy in combination with ipilimumab and nivolumab. Additional melanoma cohorts are 
offered in this trial as well to investigate Gen 3 manufacturing and PD-1 selected TIL. In 2021, we completed enrollment in an 
additional study, C-145-03, of LN-145, for recurrent and/or metastatic HNSCC.  

We are also investigating polyclonal T cell therapy in blood cancers.  Our Phase 1/2 clinical trial, IOV-CLL-01, is enrolling 

patients with CLL/SLL to receive our PBL therapy, IOV-2001. Additional information about our clinical trials is presented as follows:

Lifileucel for Metastatic Melanoma 

We are developing lifileucel to treat metastatic melanoma. Melanoma is a common type of skin cancer, accounting for 
approximately 106,110 patients diagnosed and 7,180 deaths each year in the U.S. according to the NCI’s Surveillance, Epidemiology 
and End Results program, or SEER, program. Our Phase 2 trial, C-144-01, is a prospective, registrational, four-cohort interventional 
study evaluating lifileucel in metastatic melanoma patients who have progressed after prior anti-PD-1 therapy and if BRAF mutant, 
after BRAF or BRAF/MEK inhibitor therapy. Patients enrolled in this trial to date have failed several prior treatment regimens. 
Lifileucel has received a RMAT designation from the FDA in metastatic melanoma.  

Patients with metastatic melanoma who have failed at least one treatment under the current standards of care have an 
unfavorable prognosis with very few curative treatment options. The National Comprehensive Cancer Network, or NCCN, makes 
recommendations for the treatment of patients with unresectable or metastatic melanoma. Initial therapy can include checkpoint 
inhibitors either alone or in combination (ipilimumab, nivolumab, pembrolizumab), targeted therapies for patients with BRAF 
mutations (dabrafenib/trametinib, vemurafenib/cobimetinib, or other combinations). For patients not responding or progressing and 
who have an adequate clinical status, agents selected from the previous list or of a different therapeutic class can be used as well as 
high dose IL-2. NCCN experts also recommend participating in a clinical trial at any stage of disease. Patients who do not respond to 
the current second-line therapies have very few treatment options and typically have a very poor prognosis, with limited median 
survival measured in months. According to estimates from the SEER program, there were approximately 7,180 deaths due to 
melanoma. If approved, we believe lifileucel may be able to treat a portion of the patients that have received all other approved 
treatment options. 

C-144-01 is investigating lifileucel in advanced melanoma patients who have been treated with at least one systemic therapy 
including an anti-PD-1 antibody, and if BRAF mutation positive, a BRAF inhibitor or BRAF inhibitor with MEK inhibitor. We are 
using our Gen 2 manufacturing process for most of our ongoing Phase 2 trials, and as a result, Cohort 1 of C-144-01, using our 
Generation 1, or Gen 1, manufacturing process, was closed to enrollment in 2017 and subsequent patients were enrolled in Cohorts 
2- 4, both of which use our Gen 2 process. The planned enrollment in C-144-01 was reached in late 2018 and Cohort 2 is closed to 
enrollment. Cohort 3 is a retreatment cohort. Cohort 4, a pivotal cohort, was added in 2019 and completed dosing in January 2020. 

Clinical results from Cohort 2 in the C-144-01 clinical study have been presented at several medical meetings. Initial results 
from Cohort 2 were initially reported at ASCO in June 2019 and most recently updated at ASCO in June 2021. In 66 patients with 
metastatic melanoma, treatment with lifileucel resulted in an ORR of 36%, with 2 complete responses and 22 partial responses. The 
DCR was 80%. Patients were heavily pretreated and had a mean of 3.3 prior therapies. In June 2021, we announced that median DOR 
in Cohort 2 had still not been reached after 33.1 months of median study follow up, as assessed by investigator. The adverse event 
profile was generally consistent with the underlying advanced disease and the profile of the lymphodepletion and IL-2 regimens.   

Pivotal Cohort 4 of the C-144-01 trial was enrolled to evaluate ORR as read out by an Independent Review Committee, or IRC, 
as the primary endpoint based on our interpretation of discussions with the U.S. Food and Drug Administration, or the FDA, as part of 
an End of Phase 2, or EOP2, meeting held with the FDA in the third quarter of 2018. In October 2018, based on the data provided to 
the FDA during the EOP2 meeting, we announced that lifileucel had received a Regenerative Medicines Advanced Therapy, or 
RMAT, designation from the FDA. Enrollment in Cohort 4 of the C-144-01 trial commenced in March 2019 and patient dosing was 
completed in January 2020. A total of 87 patients were dosed with Gen 2 product released for Cohort 4. In May 2020, we disclosed 
initial results from Cohort 4 for 68 patients with two radiological assessments, as determined by investigator. 

Previously, we reported the submission of additional potency assay data to the FDA, and at the same time, we also announced 
that we had reached agreement with the FDA on the minimum duration of follow up for Cohort 4 to support our BLA submission for 
lifileucel in the treatment of metastatic melanoma. In May 2021, we announced that we had received regulatory feedback from the 
FDA regarding our potency assays for lifileucel. Following FDA feedback, we have continued our ongoing work developing and 
validating our potency assays and have engaged in discussions with the FDA during the second half of 2021. Our BLA submission for 
lifileucel in metastatic melanoma is expected to occur during the first half of 2022. In connection with this BLA submission, the IRC 
is expected to independently assess responses for Cohort 4 patients through the data cut date, which must be completed prior to BLA 
submission or disclosure of IRC-read data. 

11 

Lifileucel for Cervical Cancer 

We are also developing lifileucel for the treatment of cervical cancer. Lifileucel for metastatic cervical cancer was formerly 

known as LN-145. According to estimates from the SEER program, approximately 14,480 women were diagnosed with cervical 
cancer, and approximately 4,290 cervical cancer-related deaths occurred in the U.S. 

C-145-04 is an ongoing Phase 2, multicenter pivotal trial that will assess the safety and efficacy of lifileucel for the treatment of 

patients with recurrent, metastatic or persistent cervical cancer. In February 2019, lifileucel received Fast Track designation from the 
FDA for development in the treatment of cervical cancer with disease progression on or after chemotherapy. In March 2019, the 
protocol for this trial was amended to modify the primary endpoint of ORR to be determined by IRC. In May 2019, lifileucel received 
BTD from the FDA for development in the treatment of cervical cancer. Results from the C-145-04 clinical trial were reported at 
ASCO in June 2019. In 27 patients with metastatic cervical cancer, treatment with lifileucel resulted in an ORR of 44%. In the study 
there were 3 complete responses and 9 partial responses. The DCR was 85%. Patients were heavily pretreated and had a mean of 2.4 
prior therapies. The median DOR had not been reached. The median follow-up was 7.4 months. The adverse event profile was 
generally consistent with the underlying advanced disease and the profile of the lymphodepletion and IL-2 regimens. 

Based on an EOP2 meeting held with the FDA in June 2019, the FDA has acknowledged that results from the C-145-04 clinical 

trial may be sufficient to support registration of lifileucel in the treatment of patients with metastatic cervical cancer. In accordance 
with the FDA’s recommendations, the protocol was amended, to further define the patient population in Cohort 1 as outlined below. In 
November 2019, in order to evaluate lifileucel in additional lines of therapy in cervical cancer and to address the emerging treatment 
landscape, we amended the C-145-04 trial to collect additional data on combination therapy in early-line patients as well as TIL alone 
in late-line patients. These additional cohorts also allowed access to TIL therapy when the pivotal Cohort 1 was completed. The 
C- 145-04 trial currently consists of the following cohorts of cervical cancer patients with recurrent, persistent, or metastatic disease: 

•  Cohort 1 has completed enrollment in patients who have progressed during or after systematic chemotherapy; 
•  Cohort 2 has closed enrollment to patients for treatment with lifileucel who have progressed during or after treatment with 

anti-PD-1/anti-PD-L1 checkpoint inhibitor in addition to systematic chemotherapy; 

•  Cohort 3 is enrolling patients who have not received prior systemic therapy for recurrent, metastatic, or persistent disease, 

and will explore safety and efficacy of the combination of the lifileucel regimen with pembrolizumab; 

•  Cohort 4 includes patients who have been previously enrolled but do not fit Cohort 1-3, including patients dosed with 

product produced by our Gen 1 TIL manufacturing process; and 

•  Cohort 5 is enrolling patients for retreatment with LN-145 for patients who have progressed after initial treatment with 

lifileucel. 

Given the emerging treatment landscape in cervical cancer, including the approval of pembrolizumab in combination with 

chemotherapy as a first-line treatment, we are engaging with the FDA to discuss our planned BLA submission and intend to execute 
our strategy based on feedback from the FDA for the BLA. 

LN-145 for NSCLC 

We are developing LN-145 alone and in combination with approved therapies to treat NSCLC. According to estimates from the 

SEER program, approximately 235,760 people were diagnosed with lung and bronchus cancers, and approximately 131,880 deaths 
occurred related to these cancers in the U.S. in 2021. 

In November 2020, we announced that we had finalized the protocol for our potential registrational clinical trial in NSCLC, 

IOV-LUN-202, to investigate LN-145 in patients with recurrent or metastatic NSCLC, without driver mutations, who previously 
received a single line of approved systemic therapy of combined checkpoint inhibitor and chemotherapy. The IOV-LUN-202 clinical 
trial, which continues to enroll patients, includes three cohorts. Cohorts 1 and 3 of the IOV-LUN-202 clinical trial are enrolling 
patients who presented with a PD-L1 tumor proportion score, or TPS, of less than one percent at the time they started front-line 
therapy. Cohort 2 is enrolling patients with a PD-L1 TPS of greater than or equal to one percent at the time they started front-line 
therapy. In Cohort 3 we are exploring LN-145 manufactured from core biopsy using our Gen 3 manufacturing process. Patient dosing 
commenced in IOV-LUN-202 in the second quarter of 2021 and we intend to continue to enroll patients in the IOV-LUN-202 clinical 
trial throughout 2022. 

12 

LN-145 for Head and Neck Cancer 

We are also developing LN-145 to treat head and neck cancer. According to estimates from the SEER program, approximately 
66,630 people were diagnosed with head and neck-related cancers, which are referred to by the SEER program as oral cavity, pharynx 
and larynx cancers, and approximately 14,620 head and neck-related cancer deaths occurred in the U.S.  

In June 2017, we enrolled our first patient in our ongoing Phase 2 trial, C-145-03, for the treatment of patients with recurrent 
and/or metastatic squamous cell carcinoma of the head and neck, who have failed one prior therapy. In 2018, preliminary data for 13 
patients who were administered a mix of Gen 1 and Gen 2 products, was released showing an ORR of 31%, with 4 partial responses, 
with the DOR ranging from 2.8 to 7.6 months. Patients in the study had a median of three prior therapies. The safety findings from this 
study were also consistent with previous reports. The most common TEAEs observed at the time of that data cut included chills, 
hypotension, pyrexia, hyponatremia, and anemia. As additional results are reported for the C-145-03 study, the safety profile of LN-
145 may change. We changed the design of our C-145-03 trial in 2020 so that enrolled patients would also be treated using either LN-
145 produced from the Gen 3 manufacturing process or PD-1 selected TIL, known as LN-145-S1, from the PD-1 selected TIL 
manufacturing process in two separate cohorts. In January 2021, we announced that we are closing the C-145-03 clinical trial after the 
trial reached its pre-specified enrollment target. 

Lifileucel and LN-145 in Combination with Pembrolizumab and Other Immunotherapies 

In addition to the trials for lifileucel and LN-145 mentioned above, we are developing these products alone or in combination 

with pembrolizumab or other ICIs for melanoma, head and neck and NSCLC in our clinical trial IOV-COM-202, a Phase 2, 
multicenter trial that is composed of seven cohorts. In May 2019, we reported that the first patient was dosed in the IOV-COM-202 
trial. In addition to the U.S., the IOV-COM-202 trial has active sites in Canada and in certain European countries. The IOV-COM-202 
trial now consists of the following cohorts of patients: 

•  Cohort 1A: patients with advanced unresectable or metastatic melanoma who have not received prior immunotherapy, 
including checkpoint inhibitors such as anti-PD-1/anti-PD-L1 therapy, for treatment with lifileucel in combination with 
pembrolizumab; 

•  Cohort 1B: melanoma patients who have progressed during or after treatment with anti-PD-1/anti-PD-L1 checkpoint 

inhibitor and if BRAF mutant, after BRAF or BRAF/MEK inhibitor therapy for treatment with LN-145-S1; 

•  Cohort 1C: melanoma patients who have progressed during or after treatment with anti-PD-1/anti-PD-L1 checkpoint 

inhibitor and if BRAF mutant, after BRAF or BRAF/MEK inhibitor therapy, for treatment with LN-145 manufactured 
using our Gen 3 process; 

•  Cohort 2A: patients with advanced, recurrent, or metastatic HNSCC who are naïve to prior immunotherapy including anti-

PD-1/anti-PD-L1 therapy, for treatment with LN-145 in combination with pembrolizumab; 

•  Cohort 3A: patients with NSCLC who are naïve to prior immunotherapy including anti-PD-1/anti-PD-L1 therapy, for 

treatment with LN-145 in combination with pembrolizumab; 

•  Cohort 3B: patients with NSCLC who have previously received systemic therapy, which could include checkpoint 

inhibitors or tyrosine kinase inhibitors, for treatment with LN-145 alone; and 

•  Cohort 3C: patients with NSCLC who have progressed after one prior systemic therapy for treatment with LN-145 in 

combination with ipilimumab/nivolumab. 

IOV-2001 PBL for CLL or SLL  

In November 2019, we announced that our IND for IOV-2001 was approved by the FDA and that our sponsored clinical trial 
using this therapy, IOV-CLL-01, was cleared to proceed. IOV-2001 is a non-genetically modified, polyclonal T cell product that is 
manufactured using a nine-day process from 50 mL of a patient's blood sample. IOV-2001 is under investigation in a Phase 1/2 
clinical trial for the treatment of CLL or SLL. Patients experiencing disease relapse during ibrutinib or acalabrutinib therapy treatment 
are eligible for this clinical trial. Preclinical studies of IOV-2001 have shown activity against autologous leukemia cancer cells, while 
treatment with ibrutinib and acalabrutinib has been demonstrated to improve the proliferation and effector functions of the IOV-2001 
manufactured product.

Investigator-Sponsored Clinical Trials 

TIL Therapy in Other Solid Tumor Indications  

We are collaborating with MDACC on a clinical trial to evaluate TIL therapy in sarcomas, ovarian, and thyroid cancers. These 
trials, including NCT03449108, began enrolling patients in 2018. Patients in these trials are being treated with LN-145 or LN-145-S1 
manufactured by us. 

We are also collaborating with Yale University on a clinical trial to evaluate TIL therapy in triple-negative breast cancer, or 
TNBC, NCT04111510, which opened for enrollment in 2020. Patients in this trial will be treated with LN-145 manufactured by us. 
We are also collaborating with Moffitt on a clinical trial, NCT04052334, to explore MCC TIL in adolescent and young adult patients 
with soft tissue sarcoma. 

TIL Therapy in Combination with Other Immunotherapy Drugs and/or in Earlier Lines of Therapy 

We provide funding for a clinical trial, NCT03215810, conducted by Moffitt, which seeks to evaluate TIL therapy in 

combination with the checkpoint inhibitor nivolumab in NSCLC. This study is closed to enrollment. An additional clinical trial, 
NCT02652455, is being conducted by Moffitt to evaluate TIL therapy in combination with nivolumab in metastatic melanoma. We 
have also previously collaborated with Moffitt on a clinical trial, NCT01701674, to evaluate TIL therapy in combination with the 
CTLA-4 checkpoint inhibitor ipilimumab.  

In 2019, we entered into a collaboration with Moffitt to fund a Phase 1 trial of lymphodepletion plus TIL therapy with high-

dose IL-2 in adolescent and young adult patients with soft tissue sarcoma in clinical trial NCT04052334. 

Under our CRADA, we are collaborating with the NCI on a clinical trial, NCT02621021, to evaluate TIL therapy in 

combination with the checkpoint inhibitor pembrolizumab in a 170-patient clinical trial in patients with advanced melanoma.  

We are collaborating with The Ohio State University to evaluate TIL therapy in high-risk melanoma in the neoadjuvant setting. 

This trial, NCT05176470, is expected to begin recruiting patients in 2022 who are diagnosed with stage IIIB-D melanoma that has 
spread to nearby tissue or lymph nodes (locally advanced). Patients in this trial will be treated with lifileucel manufactured by Iovance. 
The purpose of the study is to assess the feasibility of TIL expansion from all screened eligible patients who have had tumor-involved 
lymph nodes removed. 

TIL Therapy Background 

Immune System 

The immune system recognizes danger signals and responds to threats at a cellular level. The most significant components of 

the cellular aspect of the adaptive immune response are T cells, or T lymphocytes, so called because they mature in the thymus and are 
distinguished from B cells which mature in the bone marrow. T cells can be distinguished from other white blood cells by T cell 
receptors present on their cell surface. These receptors contribute to tumor surveillance by helping T cells recognize infected cells as 
well as cancerous cells. T cells are involved in both sensing and killing infected or cancerous cells, as well as coordinating the 
activation of other cells in an immune response. 

Cancer Immunotherapy 

Despite the progress that has been made over the past several decades, effective treatment of cancer, especially solid tumors, 

continues to be challenging. Some reasons solid tumors are so difficult to treat are: (i) in many solid tumors, there are multiple 
genomic mutations, as well as intratumoral heterogeneity, (ii) there are numerous tumor neoantigens, with <1% of them being shared 
across patients with the same tumor histology and it is not always clear which particular mutations are critical, and (iii) solid tumors 
can adapt and find a way to evade treatments that target a single mutation. In addition, the tumor itself and the tumor 
microenvironment can suppress the patient’s natural immune response. When T cells with cancer-specific receptors are absent, present 
in low numbers, of poor quality, or rendered inactive by suppressive mechanisms employed by tumor tissue, the cancer can grow and 
spread to various organs. In addition, standard of care treatments for cancer can be deleterious to T cells’ ability to kill cancer. 

14 

We believe that adoptive cell therapy, specifically with the use of human polyclonal TIL cells as therapeutic entities to 
reengage the immune system, may be a significant advancement in the treatment of cancer. These one-time cellular therapies may 
avoid the long-term side effects associated with current treatments and have the potential to be effective. TIL therapy has the potential 
to treat solid tumors by increasing the effectiveness and number of a patient’s cancer-specific T cells. TIL therapy is polyclonal, and 
we believe that it is capable of targeting multiple tumor antigens on cancer cells. Furthermore, the non-myeloablative, or NMA, 
lymphodepleting chemotherapy administered prior to TIL infusion is capable of suppressing the hostile tumor microenvironment, 
which we believe will enhance the efficacy of TIL therapy. 

Tumor-Infiltrating Lymphocytes 

Our Gen 2 TIL therapy involves the following steps: 

1.  Remove tumor sample: A surgical biopsy is conducted to remove about 1.5 cm of the tumor.  

2.  Expand and rejuvenate patient-specific T cells using proprietary process: The tumor is fragmented to facilitate a clear path 
for TIL to leave the tumor tissue and placed in media. The ingredients and conditions in the culture media optimize the 
growth of TIL rather than other cell types. TIL are expanded exponentially ex vivo to yield billions (109 – 1011) of TIL 
using our Gen 2 process. Our Gen 2 manufacturing process takes 22 days from receipt of the patient’s tumor at the 
manufacturing facility until cryopreservation of a product ready for shipping of the final TIL product to the institution for 
infusion of the TIL back into the patient. Initially cells grow slowly during the pre-rapid expansion, or pre-rep, phase (day 
0-11) followed by a rapid expansion, or REP phase (day 11-22). Following the pre-rep phase, the cells are transferred to a 
larger bioreactor and feeder cells are introduced to further activate the TIL to proliferate during the REP phase. On Day 
16 the TIL are harvested while maintaining a closed system before they are counted and placed into multiple bioreactors 
which are incubated one last time until Day 22. TIL are filtered, washed, concentrated and finally formulated with 
cryopreservation media on Day 22. Up to four final product bags are then prepared on Day 22, depending on total cell 
count.  

3.  Lymphodepletion and infusion: To prepare for TIL infusion, patient receives NMA lymphodepletion to eliminate 

potentially suppressive tumor microenvironment and maximize engraftment and potential potency of TIL therapy; the 
patient is infused with their expanded TIL and subsequently administered up to 6 doses of IL 2 to promote T-cell activity.  

15 

 
 
 
 
 
We currently treat patients with a single infusion of TIL product, although our protocols allow for more than one administration 

of TIL product. After infusion, TIL can potentially infiltrate the tumor microenvironment to eliminate large numbers of cancer cells. 
TIL can also further proliferate in the body. TIL therapy can potentially overcome several mechanisms of tumor escape to which 
endogenous T cells may be susceptible due to the hostile tumor microenvironment. In September 2020, we reported data at the 
European Society for Medical Oncology conference highlighting the reinvigoration of TIL during the Gen 2 manufacturing process.  

Historical Clinical Results with TIL in Metastatic Melanoma 

To date, hundreds of metastatic melanoma patients have already been treated with TIL therapy produced locally using different 

manufacturing methods at different academic institutions and hospitals in the U.S., Europe, Canada, and Israel. At the NCI, clinical 
responses have been relatively consistent in several trials that were conducted prior to anti-PD-1 treatment becoming the available 
standard of care for melanoma patients: over 50% of the melanoma patients treated with TIL achieved an objective response (i.e., 
tumor regression of 30% or more, as defined by RECIST criteria) and approximately 22-24% of patients have a complete response 
(tumor regression of 100%) with no evidence of disease remaining after only one administration. Most patients who have had a 
complete response remained in response in 3-7 years of follow up. Furthermore, patients can respond to TIL therapy regardless of 
their prior therapies. 

In September 2015, Dr. Steven Rosenberg, a recognized pioneer in immuno-oncology and adoptive cell therapy using TIL, 

presented updated findings from a Phase 2 clinical trial of TIL therapy in metastatic melanoma at the American Association for 
Cancer Research Inaugural International Cancer Immunotherapy Conference. Data was presented from a 101 patient, Phase 2 clinical 
trial conducted at the NCI. In the trial, patients with advanced metastatic melanoma were equally divided in two groups. Both groups 
were treated according to a standard TIL protocol using NMA chemotherapy, with the second group also receiving total body 
irradiation, or TBI. 54% of the patients treated with TIL therapy achieved an objective response. Out of the 101 patients, 24, or 24%, 
had experienced a complete response and 23 of the 24, or 96%, showed ongoing durability of this response at 30 to 47 months 
following treatment, at the time of publication. Median follow-up time was approximately 40.9 months. Overall survival, or OS, was 
approximately 80% at 12 months, and median OS had not yet been achieved. Median progression-free survival was approximately 
8-10 months. This observation was also presented by Dr. Stephanie Goff at the 2016 ASCO meeting and published in the Journal of 
Clinical Oncology in June 2016. At the ASCO 2018 meeting, Dr. Goff presented updated findings from the trial. Notably, patients that 
had prior anti PD-1 treatment had an ORR of 20-25%. 

In August 2021, Seitter, et al., in a collaboration led by Dr. Rosenberg from the Surgery Branch of the NCI, published in 

Clinical Cancer Research the patient outcomes based on two decades of experience with TIL therapy in metastatic melanoma. The 
ORR in the entire cohort of 226 patients was 51%, with a complete response rate of 22%. The median overall survival and median 
melanoma-specific survival were 20.6 months and 22.2 months, respectively. The patients achieving a complete response (n=49) had a 
10-year melanoma-specific survival of 96%. The ORR in the 192 patients who had not received anti-PD-1 therapy as a prior line of 
therapy was 56% with a median melanoma-specific survival of 28.5 months. Of the 43 patients who were refractory to anti-CTLA-4 
therapy without exposure to anti-PD-1, there was no difference in the response rate (60%), when compared to those naïve to any 
immune checkpoint therapy (55%). Baseline demographic features, including BRAF status did not influence outcome. Prior therapies 
including refractoriness to anti-PD-1 and BRAF/MEK inhibitors affected outcome compared to patients who had no exposure to these 
agents. Out of the 226 patients reported, 34 were refractory to anti-PD-1 therapy and had an ORR of 24%, with a median melanoma-
specific survival of 11.6 months. Decreased melanoma-specific survival was seen in patients refractory to BRAF/MEK inhibitors 
regardless of prior anti-PD-1 exposure with a median survival of 8.7 months (refractory to both anti-PD-1) and 12.1 months (naïve to 
anti-PD-1).  

Clinical Results with TIL in Other Solid Tumor Indications 

Under our CRADA with the NCI, we are providing research, development and clinical funding for the development of 
unmodified TIL therapy for a variety of solid tumor indications, including HPV-associated cancers (cervical, head and neck), 
melanoma, bladder, breast, lung cancers, glioblastoma multiforme, colorectal cancer, gastric cancer, pancreatic cancer, hepatocellular 
carcinoma and cholangiocarcinoma. Depending on results from the research and development and clinical trials conducted at the NCI 
under our CRADA, we may pursue the development and regulatory approval of TIL therapy for additional indications.

Safety 

We continue to enroll patients in our ongoing clinical programs and we closely monitor our studies to learn about all safety 

events occurring, as described elsewhere in this Annual Report on Form 10-K. Some of these events may be associated with TIL 
therapy. Historically, the largest set of data for TIL therapy was generated by the NCI as part of their multiple clinical studies. Per 
publications from the NCI, toxicities or adverse events during TIL therapy have been mostly associated with either the 
lymphodepletion regimen or the IL-2 therapy given after TIL infusion as described by Goff et al. in the Journal of Clinical Oncology 
in June 2016. The historical approach to the administration of IL-2 is to continue dosing until intolerance. Our trials, however, have 
limited administration of IL-2 to up to 6 doses. 

Next Generation TIL Product Strategies 

We are developing next generation TIL products using owned and licensed intellectual property rights, in some cases in 
combination with collaborators such as Cellectis, as described elsewhere in this Annual Report on Form 10-K. These products include 
selected TIL therapies, genetically-modified and cytokine-tethered TIL therapies. We are also developing PBL therapy for CLL and 
SLL. 

Process Development, Manufacturing, and Manufacturing Agreements 

Our first generation TIL manufacturing process was based on the NCI’s original manufacturing and processing of TIL, which 
we modified so that it could be reproduced in a cGMP environment. This first-generation process expanded the number of TIL over a 
5-to-6-week period and produced a non-cryopreserved product for administration to the patient. Our Gen 2 TIL manufacturing 
process, which was developed by our internal research and process development team, shortens the manufacturing process to 22 days 
while allowing for a cryopreserved product. The Gen 2 process is currently in use in almost all of our trials in which we manufacture 
TIL products, including lifileucel and LN-145. We have selected Gen 2 for product registration and ongoing and future TIL clinical 
development, although we continue to develop new TIL manufacturing processes. For example, at the SITC meeting in November 
2021, we presented a poster on the expansion of TIL demonstrating the use of static bags for the clinical TIL manufacturing process.  
Furthermore, we have developed a third-generation manufacturing process, known as Gen 3 which has a shorter manufacturing 
process than Gen 2. We are testing Gen 3 in multiple clinical trials, as described elsewhere in this Annual Report on Form 10-K. We 
have also developed next generation manufacturing processes to genetically modify TIL using the TALEN technology licensed from 
Cellectis, including our lead preclinical program IOV-4001, as well as selections for TIL that are PD-1 positive, such as our product 
known as LN-145-S1. 

17 

The Gen 2 manufacturing process begins with the collection of the patient’s tumor, which is then sent to a central 

manufacturing facility, where the T cells are isolated. These cells are stimulated to proliferate, then propagated in cell culture flasks 
until sufficient cells are available for infusion back into the patient. The TIL is then washed and put in media suitable for 
cryopreservation and infusion. The final product is shipped back to the clinical center where it can be administered to the patient. The 
following diagram illustrates our Gen 2 TIL manufacturing process. 

To meet projected needs for commercial quantities of TIL products, we have built our own commercial manufacturing facility, 

the iCTC, to manufacture TIL product using the Gen 2 manufacturing process. As of the end of  2021, we had completed the 
commissioning activities at the iCTC and successfully manufactured and delivered the first clinical batch of LN-145 for the IOV-
COM-202 trial, representing our first internally manufactured TIL product, as we continue our launch readiness activities to supply 
commercial TIL upon potential BLA approval. In addition, we have entered into MSAs with WuXi, Moffitt, and PharmaCell, which 
was acquired by Lonza, pursuant to which they have agreed to manufacture, package, ship and handle quality assurance and quality 
control of certain clinical trials for our TIL products working closely with our employees. We have two suites for clinical 
manufacturing at WuXi, and one of two suites is also available to manufacture TIL for commercial use. Cell processing activities are 
conducted at all facilities under cGMP, using qualified equipment and materials. We believe that all materials and components utilized 
in the production of the final TIL product are readily available from qualified suppliers. We expect to rely on our own manufacturing 
facility and these CMOs to meet anticipated clinical trial and if approved, commercial demands. In the future, we may rely on them or 
other third parties, or our own manufacturing capabilities for the manufacturing and processing of TIL-based product candidates for 
our clinical trials.  

If we are unable to meet manufacturing capabilities and demand at our own commercial manufacturing facility, we may need to 

rely on CMOs, including both current and alternate suppliers, to ensure sufficient capacity is available for commercial purposes. 

Orphan Drug Designations 

During 2015, we received an Orphan Drug Designation, or ODD, for lifileucel in the U.S. to treat malignant melanoma stages 
IIB-IV. If approved, an ODD provides seven years of market exclusivity in the U.S., subject to certain limited exceptions. However, 

18 

 
 
 
an ODD does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. The benefits and 
limitations of ODD are described in more detail elsewhere in this Annual Report on Form 10-K. 

During 2018, we received an ODD from the FDA for lifileucel for the treatment of cervical cancer with a tumor size of greater 

than 2 cm in diameter. 

Fast Track Designations 

In August 2017, we announced that the FDA had granted Fast Track designation for lifileucel for the treatment of advanced 

metastatic melanoma. In February 2019, we announced that the FDA had granted Fast Track designation for lifileucel in the treatment 
of metastatic cervical cancer. Additionally, in November 2021, we announced that the FDA granted Fast Track designation for 
lifileucel in combination with pembrolizumab for the treatment of ICI naïve metastatic melanoma based on the unmet medical need 
and potential advantages for this combination over available care. The FDA’s Fast Track process is designed to facilitate the 
development and expedite the review of drugs that treat serious conditions and fill an unmet medical need. Fast Track designation 
allows more frequent meetings and communications with the FDA to discuss the drug’s development plans and review process. The 
Fast Track designation also allows for the possibility for rolling review of a BLA by FDA, and also potential eligibility if certain 
criteria are met for accelerated approval.  

Regenerative Medicine Advanced Therapy Designation 

In October 2018, we announced that the FDA had granted RMAT designation for lifileucel for the treatment of patients with 
metastatic melanoma. The RMAT designation is based on data provided to the FDA from our C-144-01 trial. RMAT designation is 
granted for regenerative medicine drugs and allows for increased access to FDA during development. Under this designation, 
surrogate endpoints can be used to receive approval for a product, accelerated approval may be granted, and a rolling review of a BLA 
may be permitted by FDA. 

Breakthrough Therapy Designation 

In May 2019, we announced that the FDA had granted Breakthrough Therapy Designation, or BTD, for lifileucel for the 

treatment of patients with metastatic cervical cancer.  The BTD was granted based on data provided to the FDA from our C-145-04 
trial. Under a BTD, the FDA may take actions that help expedite the development and review of the application for a product 
candidate, including seeking to provide timely advice and interactive communications to the sponsor with intensive guidance during 
development, to help the sponsor design and conduct a more efficient development program. Product candidates with BTD may be 
suitable for alternative clinical trial designs when scientifically appropriate, which may result in smaller trials or more efficient trials 
that require less time to complete. BTD also allows the sponsor to file sections of the BLA on an ongoing basis for rolling review 
where the FDA may consider beginning review portions of a marketing application before the full submission is complete. In addition, 
BTD status allows for the potential to request priority review of our BLA at the time of BLA submission if supported by clinical data. 
The clinical evidence needed to support breakthrough designation is preliminary, and the FDA has authority to rescind a BTD if a 
product candidate no longer meets the qualifying criteria. 

Commercialization Plan 

We currently have limited sales, marketing or commercial product distribution capabilities and as a company we have no 

experience in commercializing cell therapy products. We are continuing to build our U.S. commercial and medical affairs 
infrastructure and intend to build our own global commercialization capabilities over time in certain geographies for our TIL product 
candidates including lifileucel for metastatic melanoma and cervical cancer. If any of our TIL product candidates are approved, we 
expect to commercialize those products in the U.S. with an experienced sales, marketing, payer access and distribution organization 
including a national specialty oncology sales force. We have started and continue to build a dedicated team of medical affairs 
professionals to help educate health professionals about our TIL therapy and to assist in any training necessary for individual centers 
to administer our therapy. Outside the U.S., we are in the process of defining our regulatory and commercial strategy. As additional 
product candidates advance through our pipeline, our commercial plans will evolve as we consider elements such as the market 
potential. 

19 

The five primary areas of our pre-launch efforts include: 

• 
• 

• 
• 
• 

engagement with potential authorized treatment centers, or ATCs, for commercial launch; 
development of a close collaboration with healthcare professionals, or HCPs, who will be handling or administering our 
product; 
operational excellence by us in provision of our product; 
communication with payors; and 
building a patient-centric organization. 

To date, in the U.S., lifileucel has been administered in 19 clinical trial centers for melanoma. We anticipate that these clinical 

trial centers will be among the initial 40 ATCs at launch upon approval. 

Intellectual Property 

Intellectual property is of importance in our field and in biotechnology generally. We seek to protect and enhance proprietary 

technology, inventions, and improvements that are commercially important to the development of our business by seeking, 
maintaining, and defending patent rights, whether developed internally or licensed from third parties. We also plan to rely on 
regulatory protection afforded through ODDs, available regulatory exclusivities and patent term extensions where available. To 
achieve this objective, a strategic focus for us has been to develop our own intellectual property, while also identifying and licensing 
patents that provide protection and serve as an optimal platform to enhance our intellectual property and technology base. We expect 
to further develop our patent portfolio as a strategic focus in 2021. 

We have developed our own patent portfolio based on internal research and development activities. As a result, we now own a 
number of pending patent applications and granted patents in the fields of TIL therapy, MIL therapy, and PBL therapy, TIL, MIL, and 
PBL manufacturing processes, and TIL, MIL, and PBL expansion methods. For example, we currently own more than 35 U.S. patents 
related to TIL therapy, including patents directed to compositions and methods of treatment in a broad range of cancers, such as U.S. 
Patent Nos. 10,130,659;  10,166,257; 10,272,113; 10,363,273; 10,398,734; 10,420,799; 10,463,697; 10,517,894; 10,537,595; 
10,639,330; 10,646,517; 10,653,723; 10,695,372; 10,894,063; 10,905,718; 10,918,666; 10,925,900; 10,933,094; 10,946,044; 
10,946,045; 10,953,046; 10,953,047; 11,007,225; 11,007,226; 11,013,770; 11,026,974; 11,040,070; 11,052,115; 11,052,116; 
11,058,728; 11,083,752; 11,123,371; 11,141,438 11,168,303; 11,168,304; 11,179,419; 11,202,803; 11,202,804; and 11,241,456. More 
than 30 of these patents are related to our Gen 2 TIL manufacturing processes and have terms that we anticipate will extend to January 
2038, not including any patent term extensions or adjustments that may be available. Our owned and licensed intellectual property 
portfolio also includes patent applications relating to TIL, MIL, and PBL therapies; frozen tumor-based TIL technologies; remnant 
TIL and digest TIL compositions, methods and processes; methods of treatment of a broad range of cancers using TIL therapies; 
methods of manufacturing TIL, MIL, and PBL therapies; the use of costimulatory molecules in TIL therapy and manufacturing; stable 
and transient genetically-modified TIL therapies; methods of using ICIs in combination with TIL therapies; TIL selection 
technologies; and methods of treating patient subpopulations. 

Research, Development and License Agreements 

Currently, preclinical research and development is conducted primarily at our own internal research and development 
laboratory in Tampa, Florida, and additionally with the NCI, Moffitt, and MDACC, as described below. We sponsor our own clinical 
trials and also collaborate on investigator-sponsored clinical trials with the NCI, Moffitt, and MDACC. 

In addition, we hold exclusive, co-exclusive, and non-exclusive licenses to certain patent and other intellectual property rights 
with the NIH, an agency of the U.S. Public Health Service within the Department of Health and Human Services, Moffitt, MDACC, 
Novartis, and Cellectis as described in this Annual Report on Form 10-K. 

National Institutes of Health and the National Cancer Institute 

Cooperative Research and Development Agreement 

In August 2011, we signed a five-year CRADA with the NCI, to work with Dr. Steven Rosenberg on developing adoptive cell 

immunotherapies that are designed to destroy metastatic melanoma cells. 

20 

In January 2015, we executed an amendment to the CRADA to include four new indications. As amended, in addition to 

metastatic melanoma, the CRADA included the development of TIL therapy for the treatment of patients with bladder, lung, triple-
negative breast, and cancers associated with HPV.  

In August 2016, the NCI and we entered into a second amendment to the CRADA. The principal changes effected by the 
second amendment included (i) extending the term of the CRADA by another five years to August 2021, and (ii) modifying the focus 
on the development of unmodified TIL as a stand-alone therapy or in combination with products licensed by the FDA, and 
commercially available reagents routinely used for adoptive cell therapy. The parties have continued the development of improved 
methods for the generation and selection of TIL with anti-tumor reactivity in metastatic melanoma, bladder, lung, breast, and HPV-
associated cancers. 

In August 2021, the NCI and we entered into a third amendment to the CRADA. The third amendment, among other things, 

extended the term of the CRADA by three years to August 2024. The research plan in this amendment includes the evaluation in 
clinical trials of strategies for development of more potent TILs, such as selection of CD39/69 double negative cells and the use of 
certain inhibitors or other reagents in TIL expansion cultures. 

Pursuant to the terms of the CRADA, as amended, we are required to make quarterly payments of $0.5 million to the NCI for 
support of research activities. To the extent we license patent rights relating to a TIL-based product candidate, we will be responsible 
for all patent-related expenses and fees, past and future, relating to the TIL-based product candidate. In addition, we may be required 
to supply certain test articles, including TIL, grown and processed under cGMP conditions, suitable for use in clinical trials. We or the 
NCI may unilaterally terminate the CRADA for any reason or for no reason at any time by providing written notice at least 60 days 
before the desired termination date. 

Patent License Agreement Related to the Development and Manufacture of TIL 

Effective October 5, 2011, we entered into an Exclusive Patent License Agreement, or the Patent License Agreement, with the 

NIH, which was subsequently amended on February 9, 2015 and October 2, 2015. Pursuant to the Patent License Agreement as 
amended, the NIH granted us licenses, including exclusive, co-exclusive, and non-exclusive licenses, to certain technologies relating 
to autologous tumor infiltrating lymphocyte adoptive cell therapy products for the treatment of metastatic melanoma, lung, breast, 
bladder and HPV-positive cancers, or collectively the Indications. The Patent License Agreement requires us to pay royalties based on 
a percentage of net sales (which percentage is in the mid-single digits), a percentage of revenues from sublicensing arrangements, and 
lump sum benchmark royalty payments on the achievement of certain clinical and regulatory milestones for each of the Indications 
and other direct costs incurred by the NIH pursuant to the agreement.  

Effective May 6, 2021, we entered into an Amended and Restated Patent License Agreement with NIH, or the Amended and 
Restated Patent License Agreement, which includes the grant of additional exclusive, worldwide patent rights in the Indications to 
cytokine-tethered TIL technology, and expands the non-exclusive, worldwide field of use to all cancers. The Amended and Restated 
Patent License Agreement requires us to pay royalties based on a percentage of net sales in jurisdictions where patent rights exist, 
which percentage can fall into a tier that may be less than one percent to mid-single digits depending upon certain events, including 
the exclusivity of the rights, and we expect lower overall royalty payments as a result. We also agreed to pay potential milestone 
payments on the achievement of certain clinical, regulatory, and commercial sales milestones for each of the Indications and other 
direct costs incurred by the NIH pursuant to the Amended and Restated Patent License Agreement, as well as a percentage of revenues 
from sublicensing arrangements. We anticipate making milestone payments, including a payment in the low single-digit millions of 
dollars, in conjunction with the approval of a BLA for any of our product candidates covered by the Amended and Restated Patent 
License Agreement. The term of the Amended and Restated Patent License Agreement continues until the expiry of the last-to-expire 
patent rights licensed thereunder, and the agreement contains standard termination provisions. 

Exclusive Patent License Agreement Related to TIL Selection 

On February 10, 2015, we entered into an exclusive patent license agreement, or the Exclusive Patent License Agreement, with 

the NIH under which we received an exclusive license to the NIH’s rights to patent-pending technologies related to methods for 
improving adoptive cell therapy through more potent and efficient production of TIL from melanoma tumors by selecting for T cell 
populations that express various inhibitory receptors. Unless terminated sooner, the license shall remain in effect until the last licensed 
patent right expires. Under the Exclusive Patent License Agreement, we agreed to pay customary royalties based on a percentage of 
net sales of a licensed product (which percentage is in the mid-single digits), a percentage of revenues from sublicensing 

21 

arrangements, and lump sum benchmark payments upon the successful completion of clinical studies involving licensed technologies, 
the receipt of the first FDA approval or foreign equivalent for a licensed product or process resulting from the licensed technologies, 
the first commercial sale of a licensed product or process in the U.S., and the first commercial sale of a licensed product or process in 
any foreign country. 

H. Lee Moffitt Cancer Center 

Research Collaboration and Clinical Grant Agreements with Moffitt 

In December 2016, we entered into a three-year Sponsored Research Agreement with Moffitt, which expired in December 
2019. In June 2020, we entered into a new Sponsored Research Agreement with Moffitt, with a term that ends either upon completion 
of the research thereunder or on July 1, 2022, whichever is sooner, and under which immaterial payments will be made to Moffitt in 
connection with the research services thereunder. In December 2016, we entered into a clinical grant agreement with Moffitt to 
support an ongoing clinical trial at Moffitt that combines TIL therapy with nivolumab for the treatment of patients with metastatic 
melanoma. In June 2017, we entered into a second clinical grant agreement with Moffitt to support a new clinical trial at Moffitt that 
combines TIL therapy with nivolumab for the treatment of patients with non-small cell lung cancer, under which we obtained a non-
exclusive, royalty-free license to any new Moffitt inventions made in the performance of the agreement. Under both clinical grant 
agreements with Moffit, we have non-exclusive rights to clinical data arising from the respective clinical trials. 

Exclusive License Agreements with Moffitt 

We entered into a license agreement with Moffitt, or the First Moffitt License, effective as of June 28, 2014, under which we 
received a world-wide license to Moffitt’s rights to patent-pending technologies related to methods for improving TIL for adoptive 
cell therapy using toll-like receptor agonists. Unless earlier terminated, the term of the license extends until the earlier of the 
expiration of the last issued patent related to the licensed technology or 20 years after the effective date of the license agreement. 

Pursuant to the First Moffitt License, we paid an upfront licensing fee in the amount of $0.1 million. A patent issuance fee will 
also be payable under the First Moffitt License, upon the issuance of the first U.S. patent covering the subject technology. In addition, 
we agreed to pay milestone license fees upon completion of specified milestones, customary royalties based on a specified percentage 
of net sales (which percentage is in the low single digits) and sublicensing payments, as applicable, and annual minimum royalties 
beginning with the first sale of products based on the licensed technologies, which minimum royalties will be credited against 
the percentage royalty payments otherwise payable in that year. We will also be responsible for all costs associated with the 
preparation, filing, maintenance and prosecution of the patent applications and patents covered by the First Moffitt License related to 
the treatment of any cancers in the U.S., Europe and Japan and in other countries designated by us in agreement with Moffitt. 

We entered into a second license agreement with Moffitt effective as of May 7, 2018, or the Second Moffitt License, under 

which we received an exclusive license to Moffitt’s rights to patent-pending technologies related to the use of 4-1BB agonists in 
conjunction with TIL manufacturing processes and therapies. Pursuant to the Second Moffitt License, we paid an upfront licensing fee 
in the amount of $0.1 million in 2018. An annual license maintenance fee is also payable commencing on the first anniversary of the 
effective date. In addition, we agreed to pay an annual commercial use payment for each indication for which a first sale has occurred. 
We subsequently exercised an option to exclusively license Moffitt’s rights to patent pending technologies related to the use of tumor 
digests in conjunction with TIL manufacturing processes and therapies, and we and Moffitt amended and restated the Second Moffitt 
License in October 2021, or the Amended & Restated Second Moffit License, to include these rights. Pursuant to the Amended & 
Restated Second Moffitt License, we paid an upfront licensing fee in the amount of $0.2 million in 2021. In addition, we agreed to pay 
an annual commercial use payment for each indication for which a first sale has occurred for products relating to the use of 4-1BB 
antagonists and for products relating to the use of tumor digests covered by the license. 

The University of Texas M.D. Anderson Cancer Center 

Strategic Alliance Agreement 

In April 2017, we entered into a Strategic Alliance Agreement, or the SAA, with MDACC agreed to conduct clinical and 

preclinical research studies. We agreed in the SAA to provide total funding not to exceed approximately $14.2 million for the 
performance of the multi-year studies under the SAA. In return, we acquired all rights to inventions resulting from the studies and 
have been granted a non-exclusive, sub-licensable, royalty-free, and perpetual license to specified background intellectual property of 

22 

MDACC reasonably necessary to exploit, including the commercialization thereof. We have also been granted certain rights in clinical 
data generated by MDACC outside of the clinical trials to be performed under the SAA. The SAA’s term shall continue in effect until 
the later of the fourth anniversary of the SAA or the completion or termination of the research and receipt by us of all deliverables due 
from MDACC thereunder. In May 2017, we made a prepayment of $1.4 million under this agreement. In light of the disease caused by 
the novel coronavirus, SARS-CoV-2, which was declared a public health emergency on January 31, 2020, under section 319 of the 
Public Health Service Act (42 U.S.C. 247d) by the Secretary of Health and Human Services, and which we refer to herein as the 
COVID-19 pandemic, MDACC temporarily suspended their research programs and decommissioned their research labs, and as a 
result, enrollment in our MDACC-sponsored studies under the SAA was temporarily paused in the first half 2020, but has since been 
restarted. 

WuXi Advanced Therapies, Inc. 

In November 2016, we entered into a three-year manufacturing and services agreement, or MSA, with WuXi, pursuant to which 

WuXi agreed to provide manufacturing and other services, which has since been amended and assigned to our subsidiary Iovance 
Biotherapeutics Manufacturing LLC. Under the agreement, we entered into two statements of work for two cGMP manufacturing 
suites to be established and operated by WuXi for us, and both of the suites are expected to be capable of being used for the 
commercial manufacture of our products. The first statement of work was amended in June 2019, September 2020, and February 
2021, and the second statement of work was amended in July 2019 and July 2021. Both statements of work provide for adjustments to 
the targeted production capacity levels and the corresponding fixed fees upon written notice from us of 30 days and 90 days for the 
first and second suites, respectively. The terms of the related statements of work currently extend to February 2022 for the first 
statement of work and were extended to December 2022 for the second statement of work. 

Cellectis S.A. 

In December 2019, we entered into a research collaboration and exclusive worldwide license agreement under which we license 

gene-editing technology from Cellectis. Financial terms of the license include development, regulatory and sales milestone payments 
from us to Cellectis, as well as royalty payments based on net sales of TALEN-modified TIL products.  

Novartis Pharma AG 

In January 2020, we obtained a license from Novartis Pharma AG, or Novartis, to develop and commercialize an antibody 

cytokine engrafted protein, which we refer to as IOV-3001. Under the agreement, we have paid an upfront payment to Novartis and 
may pay future milestones related to initiation of patient dosing in various phases of clinical development for IOV-3001 and approval 
of the product in the U.S., the European Union, or EU, and Japan. Novartis is also entitled to low-to-mid single digit percentage 
royalties from commercial sales of the product. 

Competition 

The biotechnology and pharmaceutical industries put significant resources in developing novel and proprietary therapies for the 

treatment of cancer. We compete with multiple entities who have developed and are developing immuno-oncology therapies, 
including large and specialty pharmaceutical and biotechnology companies, academic research institutions and governmental agencies 
and public and private research institutions, as well as companies developing novel targeted therapies for cancer. Universities and 
public and private research institutions in the U.S. and Europe are also potential competitors. For example, a Phase 3 study comparing 
TIL to standard ipilimumab in patients with metastatic melanoma is currently being conducted in Europe by the Netherlands Cancer 
Institute, the Copenhagen University Hospital at Herlev, and the University of Manchester. While these universities and public and 
private research institutions primarily have educational objectives, they may develop proprietary technologies that lead to other FDA-
approved therapies or that secure patent protection. We anticipate that we will face possibly increasing competition as new drugs and 
therapies enter the market and advanced technologies become available. 

Due to the promising clinical therapeutic effect of their therapies in clinical exploratory trials, we anticipate substantial direct 
competition from other organizations developing advanced T cell therapies targeting patients who have received prior anti-PD-1/PD-
L1 therapies. In particular, we expect to compete with other new therapies for our lead indications developed by companies such as 
Agenus, BeyondSpring, Bristol-Myers Squibb, Merck, Nektar Therapeutics, Idera Pharmaceuticals, Checkmate Pharmaceuticals, 
Daiichi Sankyo, Eisai, Exelixis, Mirati Therapeutics, OncoSec Medical, Replimune, Regeneron Pharmaceuticals, Seagen, and 
Genmab. We also may compete with other TIL therapies in development by companies such as Instil Bio, Achilles Therapeutics, KSQ 

23 

 
Therapeutics, Obsidian Therapeutics, Immatics, TILT Biotherapeutics, WindMIL Therapeutics, GRIT Biotechnology, Lyell 
Immunopharma, Cellular Biomedicine Group, and others. We also may compete with therapies based on genetically engineered T cell 
receptors rendered reactive against tumor-associated antigens prior to their administration to patients, as well as TIL therapies that are 
designed to be specific to neoantigens, including products developed by Adaptimmune Therapeutics, Alaunos Therapeutics, Marker 
Therapeutics, Turnstone Biologics, Neogene and others. To date, these technologies have been primarily applicable to hematologic 
malignancies, but their application in solid tumor indications may create competition with us. 

Competition for late-stage melanoma patients may come, if approved, from several therapies currently under clinical 
development across our lead indications in metastatic melanoma, non-small cell lung and cervical cancers. If we are successful in 
developing lifileucel for metastatic melanoma, we will compete against other investigational agents in late-stage development for use 
in combination with approved anti-PD-1 therapies at Bristol-Myers Squibb (relatlimab, a LAG-3-blocking antibody), Idera 
Pharmaceuticals (IMO-2125, a toll-like receptor, or TLR, 9 agonist), Checkmate Pharmaceuticals (CMP-001, a TLR9 agonist), Eisai 
(levatinib, a multiple tyrosine kinase inhibitor) and Replimune (RP1, or vusolimogene oderparepvec, an oncolytic virus therapy).   

Competition for lifileucel in late-stage cervical cancer patients also may arise from approved therapy TIVDAK™ (tisotumab 
vedotin-tftv) from Seagen/Genmab as well as an investigational agent in clinical development at Agenus (balstilimab, an anti-PD-1 
therapy) for use in combination with approved anti-CTLA-4 inhibitor zalifrelimab. In addition, the cervical cancer treatment landscape 
has further evolved with the approval of KEYTRUDA + chemo + bevacizumab in front-line cervical cancer. 

We may also face competition for NSCLC patients from a large number of therapies in clinical development that target 

specific, emerging driver mutations in populations that overlap with our patient populations of interest, including Daiichi 
Sankyo/Astra Zeneca (datopotamab deruxtecan, an antibody-drug candidate), as well as sponsors with anti-PD-1 combinations in 
clinical development such as Exelixis (cabozantinib + atezolizumab), Mirati Therapeutics (sitravatinib + nivolumab) and Merck 
(vibostolimab alone and in combination with pembrolizumab). The studies for these NSCLC therapies are in various stages of the 
clinical pipeline, including several in Phase 3 trials. 

While other types of cancer immunotherapies may potentially be used in combination with TIL, such as checkpoint inhibitors, 

to enhance efficacy, we also expect substantial direct competition from other types of immunotherapies. We face competition from 
immunotherapy treatments offered by companies such as Amgen, AstraZeneca, Bristol-Myers Squibb, Merck, Pfizer, Regeneron 
Pharmaceuticals, and Roche. Immunotherapies are also being pursued by several biotechnology companies as well as by large 
pharmaceutical companies. We cannot predict whether other types of immunotherapies may be enhanced and show greater efficacy. 
As a result, we may have direct and substantial competition from such immunotherapies in the future. 

 Many potential competitors, either alone or with their strategic partners, have substantially greater financial, technical and 

human resources than we do. Accordingly, our competitors may be more successful than us in obtaining approval for treatments and 
achieving widespread market acceptance and may render our treatments obsolete or non-competitive. Mergers and acquisitions in the 
biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our 
competitors. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and 
establishing clinical study sites and patient registration for clinical studies, as well as in acquiring technologies complementary to, or 
necessary for, our programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through 
collaborative arrangements with large and established companies. 

 Our commercial success may depend in part on our ability to obtain and maintain patent and other proprietary protection for 
commercially important technology, inventions and know-how related to our business; defend and enforce our patents; preserve the 
confidentiality of our trade secrets; and operate without infringing the valid enforceable patents and proprietary rights of third parties. 
Our ability to stop third parties from making, using, selling, offering to sell or importing our products may depend on the extent to 
which we have rights under valid and enforceable patents or trade secrets that cover these activities. With respect to both licensed and 
company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent 
applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or 
any patents that may be granted to us in the future will be commercially useful in protecting our commercial products and methods of 
manufacturing the same. We may rely, in some circumstances, on trade secrets to protect our technology. However, trade secrets can 
be difficult to protect. 

We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our 

employees, consultants, scientific advisors and contractors. We also seek to preserve the integrity and confidentiality of our data and 

24 

trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology 
systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be 
breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be 
independently discovered by competitors. To the extent that our consultants, contractors or collaborators 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. 

Government Regulations 

The FDA and other regulatory authorities at federal, state, and local levels, as well as in foreign countries, extensively regulate, 

among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, 
packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring, and post-
approval reporting of biologics such as those we are developing. We, along with our third-party contractors, will be required to 
navigate the various preclinical, clinical and commercial approval and post-approval requirements of the governing regulatory 
agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The process of 
obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and 
regulations require the expenditure of substantial time and financial resources. 

 Biologic products are regulated by the FDA under a combination of the federal Food, Drug, and Cosmetic Act, or FDCA, and 
Public Health Services Act, or PHSA, and the FDA’s implementing regulations. Failure to comply with regulatory requirements may 
result in significant regulatory actions. Such actions may include refusal to approve pending applications, license suspension or 
revocation, withdrawal of an approval, imposition of a clinical hold or termination of clinical trials, warning letters, untitled letters, 
modification of promotional materials or labeling, provision of corrective information, imposition of post-market requirements 
including the need for additional testing, imposition of distribution or other restrictions under a Risk Evaluation and Mitigation 
Strategy, or REMS, product recalls, product seizures or detentions, refusal to allow imports or exports, total or partial suspension of 
production or distribution, FDA debarment, injunctions, fines, consent decrees, corporate integrity agreements, debarment from 
receiving government contracts and new orders under existing contracts, exclusion from participation in federal and state healthcare 
programs, restitution, disgorgement, or civil or criminal penalties, including fines and imprisonment, and adverse publicity, among 
other adverse consequences. 

The process required by the FDA before biologic product candidates may be marketed in the U.S. generally involves the 

following: 

• 

• 

• 

• 

• 
• 
• 
• 

completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s current Good 
Laboratory Practices, or GLP, regulation, as well as manufacturing development and formulation studies; 
submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical 
trials may begin and must be updated annually or when significant changes are made; 
approval by an independent Institutional Review Board, or IRB, or ethics committee at each clinical site or centrally, 
before the trial is begun; 
performance of adequate and well-controlled human clinical trials to establish the safety, and efficacy of the proposed 
biologic product candidate for its intended purpose; 
preparation of and submission to the FDA of a BLA, after completion of pivotal clinical trial(s); 
satisfactory completion of an FDA Advisory Committee review, if applicable; 
a determination by the FDA within 60 days of its receipt of a BLA to file the application for review; 
satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed 
product is produced to assess compliance with cGMP, and to assure that the facilities, methods and controls are adequate to 
preserve the biological product’s continued safety, purity and potency, and of selected clinical sites to assess compliance 
with current Good Clinical Practices, or cGCPs; and 

•  FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in 

the U.S., which must be updated periodically when changes are made. 

 The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any 
approvals for our product candidates will be granted on a timely basis, if at all. Prior to beginning the first clinical trial with a new 
product candidate, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an 
investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the 
protocol(s) for clinical studies. The IND also includes results of animal and in vitro studies assessing the toxicology, 

25 

pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product; chemistry, manufacturing, and controls 
information; and any available human data or literature to support the use of the investigational product. An IND must become 
effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless 
the FDA, within the 30-day time period, raises concerns or questions about the proposed clinical trial. In such a case, the IND may be 
placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial 
can begin. Clinical holds also may be imposed by the FDA at any time before or during trials due to safety concerns or non-
compliance. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial. 

Human immunotherapy products are a new category of therapeutics. Because this is a relatively new and expanding area of 
novel therapeutic interventions, there can be no assurance as to the length of the trial period, the number of patients the FDA will 
require to be enrolled in the trials in order to establish the safety, efficacy, purity and potency of immunotherapy products, or that the 
data generated in these trials will be acceptable to the FDA to support marketing approval. 

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified 

investigators in accordance with cGCPs, which include the requirement that all research subjects provide their informed consent for 
their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things, the objectives of 
the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated, and a statistical analysis plan. 
A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and 
for any subsequent protocol amendments. Investigators must also provide certain information to the clinical trial sponsors to allow the 
sponsors to make certain financial disclosures to the FDA.  

Furthermore, an independent IRB for each site proposing to conduct the clinical trial or centrally must review and approve the 
plan for any clinical trial, its informed consent form and any subject communications, before the clinical trial begins at that site, and 
upon amendment of the trial, and must monitor the study until completed. An IRB considers, among other things, whether the risks to 
individuals participating in the trials are minimized and are reasonable in relation to anticipated benefits and whether the planned 
human subject protections are adequate. Informed consent must be received from each study subject prior to participation in a clinical 
study. Progress reports detailing the results of the clinical trials must also be submitted at least annually to the FDA and the IRB and 
more frequently if serious adverse events or other significant safety information is found. 

Regulatory authorities, the IRB, or the sponsor may suspend a clinical trial at any time on various grounds, including a finding 

that the subjects are being exposed to an unacceptable health risk, that the trial is not being conducted in accordance with regulatory or 
IRB requirements, or that the trial is unlikely to meet its stated objectives. Sponsors may also discontinue studies or development 
programs for many reasons, including changing business objectives. Some studies also include oversight by an independent group of 
qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, or DSMB, which provides 
recommendations and assessments for whether or not a study should move forward at designated check points based on access to 
certain data from the study. Following a review by a DSMB, the study may be halted if there is an unacceptable safety risk for subjects 
or on other grounds, such as failure to demonstrate efficacy. There are also requirements governing the reporting of ongoing clinical 
studies and clinical study results to public registries. For instance, we are required to register certain clinical trials and post the results 
of certain completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes, and also to 
certify to FDA our compliance with these requirements when we make FDA submissions. Failure to make required ClinicalTrials.gov 
submissions, submitting false or misleading information to ClinicalTrials.gov, or making false certifications to FDA could result in 
enforcement actions, including civil money penalties and adverse publicity. 

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap. 

Although these are the typical phases for progression, and characteristics of the phases of a clinical development program, certain 
expedited programs allow for variations that could support a marketing application based on surrogate endpoints, intermediate clinical 
endpoints, or single-arm as opposed to comparative or placebo-controlled studies. 

•  Phase 1 - The investigational product is initially introduced into healthy human subjects or patients with the target disease 
or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the 
investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence 
on effectiveness. 

•  Phase 2 - The investigational product is administered to a limited patient population with a specified disease or condition to 
evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and 

26 

safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more 
expensive Phase 3 clinical trials. 

•  Phase 3 - The investigational product is administered to an expanded patient population in adequate and well-controlled 
studies to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for 
safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the 
overall risk/benefit relationship of the investigational product and to provide an adequate basis for product approval. 
Typically, two Phase 3 studies are required by the FDA for product approval. 

•  Phase 4 - In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a 

product is approved to gain more information about the product. These so-called Phase 4 studies may be made a condition 
to approval of the BLA. 

Additional types of data may also help to support a BLA, such as real-world evidence and patient experience data. Phase 1, 
Phase 2 and Phase 3, and Phase 4 testing, if applicable, may not be completed successfully within a specified period, if at all, and there 
can be no assurance that the data collected will support FDA approval or licensure of the product. Concurrent with clinical trials, 
companies may complete additional animal studies and develop additional information about the biological characteristics of the 
product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP 
requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, 
among other things, must develop methods for testing the identity, strength, quality and purity of the final product, or for biologics, the 
safety, purity and potency. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to 
demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life and manufacturing processes 
must be validated. 

The manufacture of investigational biologics for the conduct of human clinical trials is subject to cGMP requirements. 

Investigational biologics and active ingredients imported into the U.S. are also subject to regulation by the FDA relating to their 
labeling and distribution. Further, the export of investigational products outside of the U.S. is subject to regulatory requirements of the 
importing country as well as U.S. export requirements under the FDCA. Additional U.S. and foreign laws and regulations may also be 
applicable to the handling, import, export, and transportation of biological materials, including tissue samples. 

During the development of a new therapeutic, a sponsor may be able to request a Special Protocol Assessment, or SPA, the 

purpose of which is to reach an agreement with the FDA on the Phase 3 clinical trial protocol design and analysis that will form the 
primary basis of product approval and an efficacy claim, as well as preclinical carcinogenicity trials and stability studies. An SPA may 
only be modified with the agreement of the FDA and the trial sponsor, or if the director of the FDA reviewing division determines that 
a substantial scientific issue essential to determining the safety or efficacy of the product was identified after the testing began. An 
SPA is intended to provide assurance that, in the case of clinical trials, if the agreed upon clinical trial protocol is followed, the clinical 
trial endpoints are achieved, and there is a favorable risk-benefit profile, the data may serve as the primary basis for an efficacy claim 
in support of a BLA. However, SPA agreements are not a guarantee of approval of a product candidate or any permissible claims 
about the product candidate. In particular, SPAs are not binding on the FDA if, among other reasons, previously unrecognized public 
health concerns arise during the performance of the clinical trial, other new scientific concerns regarding the product candidate’s 
safety or efficacy arise, or if the sponsoring company fails to comply with the agreed upon clinical trial protocol. 

In addition, under the Pediatric Research Equity Act, or PREA, a BLA or supplement to a BLA for a new active ingredient, 

indication, dosage form, dosage regimen, or route of administration, must contain data that are adequate to assess the safety and 
effectiveness of the product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and 
administration for each pediatric subpopulation for which the product is safe and effective. Also, under the FDA Reauthorization Act 
of 2017, beginning in 2020, sponsors submitting applications for product candidates intended for the treatment of adult cancer which 
are directed at molecular targets that the FDA determines to be substantially relevant to the growth or progression of pediatric cancer 
must submit, with the application, reports from molecularly targeted pediatric cancer investigations designed to yield clinically 
meaningful pediatric study data, using appropriate formulations, to inform potential pediatric labeling. The FDA may, on its own 
initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the 
product for use in adults, or full or partial waivers from the pediatric data requirements. Orphan products are also exempt from PREA 
requirements. 

The FDA also may require submission of REMS, to ensure that the benefits of the biologic outweigh the risks. The REMS plan 

could include medication guides, physician communication plans, and elements to assure safe use, such as restricted distribution 
methods, patient registries, or other risk minimization tools. An assessment of the REMS must also be conducted at set intervals. 

27 

Following product approval, a REMS may also be required by the FDA if new safety information is discovered and the FDA 
determines that a REMS is necessary to ensure that the benefits of the biologic outweigh the risks. 

BLA Submission and Review by the FDA 

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of 

product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market 
the product for one or more indications. The BLA must include all relevant data available from pertinent preclinical and clinical 
studies, including negative or ambiguous results as well as positive findings, 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 studies intended to test the safety and effectiveness of a use of the product, or from a number of alternative sources, including 
studies initiated by investigators. The submission of a BLA requires payment of a substantial user fee to the FDA, under the 
Prescription Drug User Fee Act, and the sponsor of an approved BLA is also subject to annual program fees. These fees are typically 
increased annually. A waiver of user fees may be obtained under certain limited circumstances. 

Once a BLA has been submitted, the FDA has sixty days to determine whether it will accept the application for filing. The 

FDA accepts applications for filing if it determines that the application is substantially complete to permit a substantive review. The 
FDA may request additional information rather than accept a BLA 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’s goal is to review the application within ten months after it accepts the application for filing, or, if the application 

relates to a serious or life-threatening indication and, if approved, the product would provide a significant improvement in safety and 
efficacy, six months after the FDA accepts the application for filing, which is referred to as Priority Review. The review process is 
often significantly extended if the FDA requests additional information or clarification. The FDA reviews a BLA to determine, among 
other things, whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed, or held meets 
standards designed to assure the product’s continued safety, purity and potency. There are numerous FDA personnel assigned to 
review different aspects of a BLA, and uncertainties can be presented by their ability to exercise judgment and discretion during the 
review process. The development and provision of additional data and information requested by FDA during review of a BLA may be 
time consuming and expensive. 

The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a 
novel biologic, the FDA must either refer that biologic to an external advisory committee or provide in an action letter, a summary of 
the reasons why the FDA did not refer the product candidate to an advisory committee. An advisory committee is typically a panel 
that includes clinicians and other experts, which review, evaluate, and make a recommendation as to whether the application should be 
approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such 
recommendations carefully when making decisions. 

Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. 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 commercial 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.  

If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline 
the deficiencies in the submission and often will request additional testing, clinical studies, application modifications, or information 
in a complete response letter, or CRL. A CRL indicates that the review cycle for the application is complete and that the application is 
not ready for approval. If a CRL is issued, the applicant may either: resubmit the BLA, addressing all the deficiencies identified in the 
letter; withdraw the application; or request an opportunity for a hearing. Notwithstanding the submission of any requested additional 
information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. Data obtained 
from clinical trials are not always conclusive and the FDA may interpret data differently than an applicant interprets the same data. 

If the FDA finds that a BLA is approvable, the FDA may issue an approval letter. An approval letter authorizes commercial 

marketing of the product with specific prescribing information for specific indications. However, even if the FDA approves a product, 
it may limit the approved indications for use of the product, require that contraindications, warnings, or precautions be included in the 
product labeling, including a boxed warning, require that post-approval studies, including Phase 4 clinical trials, be conducted to 

28 

further assess a product’s safety and efficacy 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 under a 
REMS which can materially affect the potential market and profitability of the product. The FDA may also not approve label 
statements that are necessary for successful commercialization and marketing. 

If compliance with the pre-and post-marketing regulatory standards are not maintained or if problems occur after the product 
reaches the marketplace, the FDA may also withdraw the product approval. Further, should new safety information arise, additional 
testing, product labeling, or FDA notification may be required. 

A sponsor may seek approval of its product candidate under programs designed to accelerate the FDA’s review and approval of 
new drugs and biological products that meet certain criteria. Specifically, new drugs and biological products are eligible for Fast Track 
designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical 
needs for the condition. For a Fast Track designation, the FDA may consider sections of the BLA for review on a rolling basis before 
the complete application is submitted if relevant criteria are met. Fast Track-designated products are also eligible for more frequent 
FDA interactions. A Fast Track-designated product candidate may also qualify for Priority Review, under which the FDA sets the 
target date for FDA action on the BLA at six months after the FDA accepts the application for filing. Priority Review is granted when 
there is evidence that the proposed product would be a significant improvement in the safety or effectiveness of the treatment, 
diagnosis, or prevention of a serious condition. If criteria are not met for Priority Review, the application is subject to the standard 
FDA review period of 10 months after the FDA accepts the application for filing. Priority Review designation does not change the 
scientific/medical standard for approval or the quality of evidence necessary to support approval. 

Under the Accelerated Approval Program, the FDA may approve a BLA on the basis of either 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. To qualify for 
Accelerated Approval, the product must be intended to treat a serious condition and must generally provide a meaningful advantage 
over available therapies. Post-marketing studies or completion of ongoing studies after marketing approval are required to verify the 
biologic’s clinical benefit in relationship to the surrogate endpoint or ultimate outcome in relationship to the clinical benefit. If this 
trial is not conducted, if it fails to verify the benefit, if other evidence demonstrates that the product is not safe, pure or potent, or if the 
applicant disseminates false or misleading promotional material, the FDA may withdraw approval of the application on an expedited 
basis. Sponsors of products under the Accelerated Approval Pathway must further submit promotional materials to the FDA before 
dissemination. 

In addition, the Food and Drug Administration Safety and Innovation Act, or FDASIA, which was enacted and signed into law 

in 2012, established the new Breakthrough Therapy Designation. A sponsor may seek FDA designation of its product candidate as a 
Breakthrough Therapy if the product candidate is intended, alone or in combination with one or more other drugs or biologics, to treat 
a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the therapy may demonstrate 
substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects 
observed early in clinical development. Sponsors may request the FDA to designate a Breakthrough Therapy at the time of or any time 
after the submission of an IND, but ideally before an end-of-Phase 2 meeting with the FDA. If the FDA designates a Breakthrough 
Therapy, it may take actions appropriate to expedite the development and review of the application, which may include holding 
meetings with the sponsor and the review team throughout the development of the therapy; providing timely advice to, and interactive 
communication with, the sponsor regarding the development of the drug to ensure that the development program to gather the 
nonclinical and clinical data necessary for approval is as efficient as practicable; involving senior managers and experienced review 
staff, as appropriate, in a collaborative, cross-disciplinary review; assigning a cross-disciplinary project lead for the FDA review team 
to facilitate an efficient review of the development program and to serve as a scientific liaison between the review team and the 
sponsor; and considering alternative clinical trial designs when scientifically appropriate, which may result in smaller trials or more 
efficient trials that require less time to complete and may minimize the number of patients exposed to a potentially less efficacious 
treatment. Breakthrough Therapy designation also allows the sponsor to file sections of the BLA for review on a rolling basis. 

Through the 21st Century Cures Act, or Cures Act, Congress also established another expedited program, called a RMAT 

designation. The Cures Act directs the FDA to facilitate an efficient development program for and expedite review of RMATs. To 
qualify for this program, the product must be a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or a 
combination of such products, and not a product solely regulated as a human cell and tissue product. The product must be intended to 
treat, modify, reverse, or cure a serious or life-threatening disease or condition, and preliminary clinical evidence must indicate that 

29 

the product has the potential to address an unmet need for such disease or condition. Advantages of the RMAT designation include all 
the benefits of the Fast Track and breakthrough therapy designation programs, including early interactions with the FDA. These early 
interactions may be used to discuss potential surrogate or intermediate endpoints to support accelerated approval. 

Orphan Drugs 

Under the Orphan Drug Act, the FDA may grant ODD to a drug or biologic intended to treat a rare disease or condition, defined 

as a disease or condition with a patient population of fewer than 200,000 individuals in the U.S., or a patient population greater than 
200,000 individuals in the U.S. and when there is no reasonable expectation that the cost of developing and making available the drug 
or biologic in the U.S. will be recovered from sales in the U.S. for that drug or biologic. Additionally, sponsors must present a 
plausible hypothesis for clinical superiority to obtain ODD if there is a product already approved by the FDA that is intended for the 
same indication and that is considered by the FDA to be the same product as the already approved product. This hypothesis for clinical 
superiority must be demonstrated to obtain orphan exclusivity. ODD must be requested before submitting a BLA. After the FDA 
grants ODD, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. 

If a product that has ODD subsequently receives the first FDA approval for a particular active ingredient for the disease for 

which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any 
other applications, including a full BLA, to market the same biologic, as sameness is defined in the FDA’s regulations, for the same 
indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug 
exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of 
sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. 
Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or 
the same drug or biologic for a different disease or condition. Among the other benefits of ODD are tax credits for certain research, 
opportunities for certain research grant funding, and a waiver of the BLA application fees. The tax credit, however, was recently 
limited through Congress’s tax reform efforts. Despite these benefits, the ODD does not convey any advantage in, or shorten the 
duration of, the regulatory review or approval process. 

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication 
for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the U.S. may be lost if the FDA later 
determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of 
the product to meet the needs of patients with the rare disease or condition. The FDA may also approve a product deemed to be the 
same as an approved orphan product for the same orphan indication, despite periods of exclusivity, if the new product is demonstrated 
to be clinically superior to the former product. 

We plan to seek ODD for some or all of our other product candidates in specific orphan indications in which there is a 

medically plausible basis for the use of such products. 

Market and Data Exclusivity and Biosimilars 

While under the Biologics Price Competition and Innovation Act of 2009, or BPCIA, the FDA may eventually license products, 
as further described below, that are biosimilar to any of our product candidates that are approved, our products may receive periods of 
regulatory exclusivity, in addition to orphan drug exclusivity for those products with ODDs, providing additional protection from 
certain forms of competition. For instance, our products may receive 12 years of reference product exclusivity that begins running at 
the time of first licensure. During this 12-year time period, the FDA may not make an approval of a biosimilar product effective and 
may not accept a biosimilar application until after four years from the date of first licensure. However, certain changes and 
supplements to an approved BLA, and subsequent applications filed by the same sponsor, manufacturer, licensor, predecessor in 
interest, or other related entity do not qualify for the exclusivity period. The PHSA also includes provisions governing patent litigation 
over patents that are directed to the reference products. The biosimilar product sponsor and reference product sponsor may, but are not 
required to, exchange certain patent and product information for the purpose of negotiating and determining the scope of patent 
litigation, including the patents to be asserted and challenged. Based on the outcome of negotiations surrounding the exchanged 
information, the reference product sponsor may bring a patent infringement suit and injunction proceedings against the biosimilar 
product sponsor. The biosimilar applicant may also be able to bring an action for declaratory judgment concerning the patent under 
certain circumstances.  

30 

The BPCIA created an abbreviated approval pathway for biological products shown to be highly similar to or interchangeable 

with an FDA-licensed reference biological product. Accordingly, if we receive FDA licensure, we may face competition from 
biosimilar products. Biosimilarity sufficient to reference a prior FDA-approved product requires a high similarity to the reference 
product notwithstanding minor differences in clinically inactive components, and no clinically meaningful differences between the 
biological product and the reference product in terms of safety, purity, and potency. Biosimilarity must be shown through analytical 
studies, animal studies, and at least one clinical trial, absent a waiver by the FDA. There must be no difference between the reference 
product and a biosimilar in conditions of use, route of administration, dosage form, and strength. A biosimilar product may be deemed 
interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce the 
same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic 
may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to 
exclusive use of the reference biologic. 

Pediatric Exclusivity and Patent Term Extension 

Pediatric exclusivity is another type of non-patent marketing exclusivity in the U.S. and, if granted, provides for the attachment 
of an additional six months of marketing protection to the term of any existing regulatory exclusivity. Under the Best Pharmaceuticals 
for Children Act, a six-month exclusivity may be granted if a sponsor submits pediatric data that fairly respond to a written request 
from the FDA for such data. The data do not need to show the product to be effective in the pediatric population studied; rather, if the 
clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric 
studies are submitted to and accepted by the FDA, whatever regulatory periods of exclusivity that already cover the product are 
extended by six months. Pediatric exclusivity is thus an “add-on” exclusivity and is unique in this regard among the various regulatory 
exclusivities provided by FDA. The FDA can also require pediatric studies of a drug submitted in a new drug application if the FDA 
determines that the product is likely to be used in a substantial number of pediatric patients, or if the product would provide a 
meaningful benefit in the pediatric population over existing treatments.  This requirement may be waived in certain circumstances, for 
example, where the indication does not occur or is not highly prevent in the pediatric population. 

If approved, biologics may also be eligible for periods of U.S. patent term restoration. If granted, patent term restoration 

extends the patent life of a single unexpired patent that has not previously been extended, for a maximum of five years. The total 
patent life of the product with the extension also cannot exceed fourteen years from the product’s approval date. Subject to the prior 
limitations, the period of the extension is calculated by adding half of the time from the effective date of an IND to the initial 
submission of a marketing application, and all the time between the submission of the marketing application and its approval. This 
period may also be reduced by any time that the applicant did not act with due diligence. Whether any of our product candidates will 
be eligible for patent term restoration is currently unknown. Even if any of our product candidates are found to be eligible for patent 
term protection, the applicable authorities may subsequently determine that we are not eligible for such restoration periods. 

Post-Approval Requirements 

Any products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other 

things, record-keeping requirements, reporting of adverse experiences with the product and deviations, annual reporting and 
monitoring and providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, 
certain electronic records and signature requirements, fulfilling post-marketing study and REMS commitments, and complying with 
FDA promotion and advertising requirements, which include, among other things, standards for direct-to-consumer advertising, 
restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses or otherwise 
consistent with the FDA-approved product labeling (known as “off-label use”), limitations on industry-sponsored scientific and 
educational activities, rules regarding communication of health care economic information regarding biopharmaceutical products to 
payors and formularies, and requirements for promotional activities involving the internet. Although physicians may prescribe legally 
available products for off-label use, if they deem such use to be appropriate in their professional medical judgment, manufacturers 
may not market or promote such off-label uses. In the past several years, certain court decisions have impacted FDA’s enforcement 
activity regarding off-label promotion in light of First Amendment considerations; however, there are still significant risks in this area, 
in part due to the potential for False Claims Act exposure. 

In addition, quality control and manufacturing procedures must continue to conform to applicable manufacturing requirements 

after approval to ensure the long-term stability of the product. cGMP regulations require among other things, quality control and 
quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct 
any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved products are 

31 

required to register their establishments and list their products with the FDA and certain state agencies, and are subject to periodic 
unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other applicable laws. Accordingly, 
manufacturers must continue to expend time, money, and effort in the areas of production and quality control to maintain cGMP 
compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an 
approved BLA, including, among other things, withdrawal of approval, recall or withdrawal of the product from the market. In 
addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require 
prior FDA approval or notification before being implemented. Other types of changes to the approved product, such as adding new 
indications and claims to the product labeling, are also subject to further FDA review and approval. 

Commercial products must meet the requirements of the Drug Supply Chain Security Act, or DSCSA, which imposes 

obligations on manufacturers of prescription biopharmaceutical products for commercial distribution, regulating the distribution of the 
products at the federal level, and sets certain standards for federal or state registration and compliance of entities in the supply chain, 
including manufacturers and repackagers, wholesale distributors, third-party logistics providers, and dispensers. The DSCSA preempts 
previously enacted state laws and the pedigree requirements of the Prescription Drug Marketing Act, or PDMA. Trading partners 
within the drug supply chain must now ensure certain product tracing requirements are met that they are doing business with other 
authorized trading partners; and they are required to exchange transaction information, transaction history, and transaction statements. 
Product identifier information, an aspect of the product tracing scheme, is required. The DSCSA requirements, development of 
standards, and the system for product tracing have been and will continue to be phased in over a period of years, with the FDA 
indicating that it would permit certain exemptions and exclusions, and exercise enforcement discretion on certain aspects of the law 
due to the COVID-19 pandemic, although this situation may continue to evolve. The distribution of product samples continues to be 
regulated under the PDMA, and some states also impose regulations on drug sample distribution. 

As previously mentioned, the FDA may also require Phase 4 testing and surveillance to monitor the effects of an approved 

product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can 
have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, 
mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or 
developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings 
and contraindications, and may require the implementation of other risk management measures. Also, new government requirements, 
including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent 
regulatory approval of our products under development. 

Additional Biologic Requirements 

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of 
manufacturing controls for products whose attributes cannot be precisely defined. The PHSA also provides authority to the FDA to 
immediately suspend licenses in situations where there exists a danger to public health, to prepare or procure products in the event of 
shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or 
spread of communicable diseases in the U.S. and between states. 

After a BLA is approved, the product may also be subject to official lot release as a condition of approval. As part of the 

manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for 
distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the 
FDA, together with a release protocol showing the results of all the manufacturer's tests performed on the lot. The FDA may also 
perform certain confirmatory tests on lots of some products before releasing the lots for distribution by the manufacturer. 

In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and 
effectiveness of biological products. After approval of biologics, manufacturers must address any safety issues that arise, are subject to 
recalls or a halt in manufacturing, and are subject to periodic inspection after approval. 

Other Healthcare Laws and Compliance Requirements 

Our sales, promotion, medical education and other activities following product approval will be subject to regulation by 
numerous regulatory and law enforcement authorities in the U.S., and in addition to the FDA, these entities may include the Federal 
Trade Commission, the Department of Justice, the Centers for Medicare & Medicaid Services, other divisions of the Department of 
Health and Human Services and state and local governments. Our promotional and scientific/educational programs must comply with 

32 

the federal Anti-Kickback Statute, or AKS, the Foreign Corrupt Practices Act, or FCPA, the False Claims Act, or FCA, the Veterans 
Health Care Act, physician payment transparency laws, privacy laws, security laws, and additional state laws similar to the foregoing. 

The federal AKS prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting 

or receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, 
leasing, ordering or arranging for the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other 
federal healthcare programs, in whole or in part. The term remuneration has been interpreted broadly to include anything of value. The 
federal AKS has been interpreted broadly to apply to arrangements between pharmaceutical manufacturers on the one hand and 
prescribers, purchasers, and formulary managers on the other. The term "remuneration" includes kickbacks, bribes or rebates and also 
has been broadly interpreted to include anything of value, including, for example, gifts, discounts, waivers of payment, ownership 
interest and providing anything at less than its fair market value. Additionally, the intent standard under the federal AKS provides that 
a person or entity need not have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. 
In addition, a claim including items or services resulting from a violation of the federal AKS constitutes a false or fraudulent claim for 
purposes of the federal civil False Claims Act. There are a number of statutory exceptions and regulatory safe harbors protecting some 
common activities from prosecution or other regulatory sanctions. The exceptions and safe harbors are drawn narrowly and practices 
that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to 
scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all the requirements of a particular applicable statutory 
exception or regulatory safe harbor does not make the conduct per se illegal under the AKS. Instead, the legality of the arrangement 
will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Our practices may not in all 
cases meet all the criteria for protection under a statutory exception or regulatory safe harbor. The safe harbors are subject to change 
through legislative and regulatory action, and we may decide to adjust our business practices or be subject to heightened scrutiny as a 
result. 

The civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to 
have presented or caused to be presented a claim for payment, or approval to a federal healthcare program that the person knows or 
should know is for an item or service that was not provided as claimed or is false or fraudulent. 

The FCA imposes liability on persons who, among other things, knowingly present or cause to be presented false or fraudulent 

claims for payment to, or approval by the federal government knowingly making or using, or causing to be made or used a false 
statement or record material to a claim to the federal government, or avoiding, decreasing or concealing an obligation to pay money to 
the federal government. A claim includes "any request or demand" for money or property presented directly or indirectly to the federal 
government. The civil FCA has been or can be used to assert liability on the basis of kickbacks and other improper referrals, 
improperly reported government pricing metrics such as Best Price and Average Manufacturer Price, improper promotion of uses not 
expressly approved by the FDA in a drug’s label, false statements associated with government grants, and allegations of 
misrepresentations with respect to services rendered, as well as claims for payment that are inaccurate or fraudulent, that are for 
services not provided as claimed, or for services that are not medically necessary. FCA claims may be based on noncompliance with 
regulatory requirements under an implied certification theory if material to the government’s decision to buy or pay for a drug. Intent 
to deceive is not required to establish liability under the civil FCA. Civil FCA liability may also be imposed for Medicare or Medicaid 
overpayments caused by understated rebate amounts that are not refunded within 60 days of discovering the overpayment, even if the 
overpayment was not caused by a false or fraudulent act. Actions under the FCA may be brought by the government or as a qui tam 
action by a private individual in the name of the government. If the government intervenes in a qui tam action, and prevails, the qui 
tam plaintiff will share in the proceeds from damages and fines or settlement funds. If the government declines to intervene, the qui 
tam plaintiff may pursue the case alone. Violations of the FCA can result in significant monetary penalties and treble damages. The 
government may further prosecute conduct under the criminal FCA, which prohibits the making or presenting of a claim to the 
government knowing the claim to be false, fictitious or fraudulent. Unlike the civil FCA, conviction requires proof of intent to submit 
a false claim. In addition, federal AKS violations (which may be alleged based on certain marketing practices, including allegations of 
off-label promotion) implicate the FCA. 

The compliance and enforcement landscape, and related risk, is informed by government litigation and settlement precedent, 

Advisory Opinions, and Special Fraud Alerts.  Our approach to compliance may evolve over time in light of these types of 
developments. 

Additionally, the FCPA, and similar worldwide anti-bribery laws, generally prohibit companies and their intermediaries from 

making, offering or authorizing improper payments or other items of value, directly or indirectly, to foreign officials, political parties, 
or candidates for the purpose of obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the 

33 

U.S. to comply with accounting provisions requiring us to maintain books and records that accurately and fairly reflect all transactions 
of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls 
for international operations. Activities that violate the FCPA, even if they occur wholly outside the U.S., can result in criminal and 
civil fines, imprisonment, disgorgement, oversight, and debarment from securing government contracts. We cannot assure you that our 
internal control policies and procedures will protect us from reckless or negligent acts committed by our employees, future 
distributors, partners, collaborators or agents. Violations of these laws, or allegations of such violations, could result in fines, penalties 
or prosecution and have a negative impact on our business, results of operations and reputation. 

Payment or reimbursement of prescription drugs by Medicaid or Medicare requires manufacturers of the drugs to submit 

pricing information to the Centers for Medicare & Medicaid Services, or CMS. The Medicaid Drug Rebate statute requires 
manufacturers to calculate and report price points, which are used to determine Medicaid rebate payments shared between the states 
and the federal government and Medicaid payment rates for the drug. For drugs paid under Medicare Part B, manufacturers must also 
calculate and report their Average Sales Price or ASP, which is used to determine the Medicare Part B payment rate for the drug. 
Drugs that are approved under a BLA or a New Drug Application, or NDA, including 505(b)(2) drugs, are subject to an additional 
inflation penalty which can substantially increase rebate payments. In addition, for BLA and NDA drugs, the Veterans Health Care 
Act, or VHCA, requires manufacturers to calculate and report to the Veterans Administration, or VA, a different price called the 
Non‑Federal Average Manufacturing Price, which is used to determine the maximum price that can be charged to certain federal 
agencies, referred to as the Federal Ceiling Price, or FCP. Like the Medicaid rebate amount, the FCP includes an inflation penalty. A 
Department of Defense regulation requires manufacturers to provide this discount on drugs dispensed by retail pharmacies when paid 
by the TRICARE Program. All these price reporting requirements create risk of submitting false information to the government, and 
potential FCA liability. 

The VHCA also requires manufacturers of covered drugs participating in the Medicaid program to enter into Federal Supply 

Schedule contracts with the VA through which their covered drugs must be sold to certain federal agencies at FCP and to report 
pricing information. This necessitates compliance with applicable federal procurement laws and regulations and subjects us to 
contractual remedies as well as administrative, civil, and criminal sanctions. In addition, the VHCA requires manufacturers 
participating in Medicaid to agree to provide different mandatory discounts to certain Public Health Service grantees and other safety 
net hospitals and clinics. 

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil penalties 

prohibits, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by 
means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or 
control of, any healthcare benefit program, regardless of whether the payor is public or private third-party, knowingly and willfully 
embezzling or stealing from a health care benefit program, willfully obstructing a criminal investigation of a health care offense, and 
knowingly and willfully falsifying, concealing, or covering up by any trick or device a material fact or making any materially false 
statements in connection with the delivery of, or payment for, healthcare benefits, items, or services relating to healthcare matters. A 
person or entity does not need to have actual knowledge of the statute, or the specific intent to violate it, to have committed a 
violation. 

We may also be subject to data privacy and security laws and regulation by both the federal government and the states in which 

we conduct our business. HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and their 
respective implementing regulations, including the final omnibus rule published on January 25, 2013, imposes specific requirements 
relating to the privacy, security and transmission of individually identifiable health information held by covered entities and their 
business associates. While we would not be a “covered entity” under HIPAA, it is possible that we may enter into a service or 
business arrangement that would cause us to serve as a “business associates,” defined as a person or entity that performs certain 
functions or activities that involve the use or disclosure of protected health information in connection with providing a service for or 
on behalf of, or provide services to, a covered entity. HITECH also increased the civil and criminal penalties that may be imposed 
against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil 
actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated 
with pursuing federal civil actions. In addition, state laws govern the privacy and security of health information in certain 
circumstances, many of which differ from each other in significant ways and may not have the same effect. The Department of Health 
and Human Services Office of Civil Rights, or the OCR, has increased its focus on compliance and continues to train state attorneys 
general for enforcement purposes.  

34 

Even for entities that are not deemed “covered entities” or “business associates” under HIPAA, according to the U.S. Federal 

Trade Commission, or the FTC, failing to take appropriate steps to keep consumers’ personal information secure constitutes unfair 
acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act, or the FTCA, 15 USC § 
45(a). The FTC expects a company's data security measures to be reasonable and appropriate in light of the sensitivity and volume of 
consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce 
vulnerabilities. Medical data is considered sensitive data that merits stronger safeguards. The FTC's guidance for appropriately 
securing consumers' personal information is similar to what is required by the HIPAA Security Rule. 

In addition to the laws discussed above, we may see more stringent state and federal privacy legislation in 2021 and beyond, as 

the increased cyber-attacks during the pandemic have heightened attention data privacy and security in the U.S. and other 
jurisdictions. We cannot predict where new legislation might arise, the scope of such legislation, or the potential impact to our 
business and operations. 

Payments made to physicians and other healthcare providers, and other financial interests, have been the subject of a range of 

federal and state laws. The federal physician payment transparency requirements, sometimes referred to as the Physician Payments 
Sunshine Act, or the Sunshine Act, was created under the ACA. The Sunshine Act, among other things, imposes reporting 
requirements on drug manufacturers for payments or other transfers of value made by them to physicians and teaching hospitals, as 
well as ownership and investment interests held by physicians, other healthcare providers, and their immediate family members. 
Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 per year and up to an 
additional aggregate of $1 million per year for “knowing failures,” for all payments, transfers of value or ownership or investment 
interests that are not timely, accurately and completely reported in an annual submission. The Sunshine Act was amended requiring 
applicable manufacturers, in 2021, to begin tracking payments and transfers of value to physician assistants, nurse practitioners, and 
other mid-level HCPs as well as physicians, with reporting relative to these mid-level practitioners first due in 2022. Additionally, 
certain states also mandate implementation of commercial compliance programs, impose restrictions on drug manufacturer marketing 
practices and/or require the tracking and reporting of gifts, compensation and other remuneration to physicians and other HCPs. 

Analogous state laws and regulations, such as state anti-kickback and false claims laws, and other state laws addressing the 

pharmaceutical and healthcare industries, which may apply to items or services reimbursed by any third-party payor, including 
commercial insurers, and in some cases may apply regardless of payor, i.e., even if reimbursement is not available. Some state laws 
require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines, known as the 
PhRMA Code, and the relevant compliance program guidance promulgated by the federal government in addition to requiring drug 
manufacturers to report pricing and marketing information, including, among other things, information related to gifts, payments, or 
other remuneration to physicians and other healthcare providers or marketing expenditures, state and local laws that require the 
registration of pharmaceutical sales representatives, and state laws governing the privacy and security of health information and the 
use of prescriber-identifiable data in certain circumstances, many of which differ from each other in significant ways and may not 
have the same effect, thus complicating compliance efforts. For example, California enacted the California Consumer Privacy Act, or 
CCPA, which went into effect on January 1, 2020 and was recently amended and expanded by the California Privacy Rights Act, or 
CPRA, passed on November 3, 2020. While the majority of the CPRA’s substantive provisions will not take effect until January 1, 
2023, the CPRA’s expansion of the “Right to Know” impacts personal information collected on or after January 1, 2022. Companies 
must still comply with the CCPA during the ramp up period before CPRA goes into effect. The CCPA and CPRA, among other 
things, create new data privacy obligations for covered companies and provides new privacy rights to California residents, including 
the right to opt out of certain disclosures of their information. The CCPA also created a private right of action with statutory damages 
for certain data breaches, thereby potentially increasing risks associated with a data breach. It remains unclear what, if any, additional 
modifications will be made to the CPRA by the California legislature or how it will be interpreted. Therefore, the effects of the CCPA 
and CPRA are significant and will likely require us to modify our data processing practices, and may cause us to incur substantial 
costs and expenses to comply. 

To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and regulations, 

which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti‑fraud and abuse laws, and 
implementation of corporate compliance programs and reporting of payments or transfers of value to HCPs. 

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under such laws, 
it is possible that certain business activities could be subject to challenge under one or more of such laws. The scope and enforcement 
of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the 
lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of 

35 

interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, 
convictions and settlements in the healthcare industry. Ensuring that business arrangements with third parties comply with applicable 
healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and 
can divert management's attention from the business. 

If our operations are found to be in violation of any of such health regulatory laws described above or any other governmental 
laws and regulations that apply to us, we may be subject to penalties, including, without limitation, civil, administrative, and criminal 
penalties, damages, fines, disgorgement, the curtailment or restructuring of our operations, exclusion from participation in federal and 
state healthcare programs and individual imprisonment, injunctions, private qui tam actions brought by individual whistleblowers in 
the name of the government, as well as additional reporting obligations and oversight if we become subject to a corporate integrity 
agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely affect our 
ability to operate our business and our financial results. 

Coverage and Reimbursement 

Sales of pharmaceutical products depend significantly on the availability of third-party coverage and reimbursement. Third-

party payors include Medicare, Medicaid, and other government programs at the federal and state level, managed care providers, 
private health insurers and other organizations. Third party payors decide which drugs they will pay for on behalf of their beneficiaries 
and establish reimbursement levels for health care. Although we currently believe that third-party payors will provide coverage and 
reimbursement for our product candidates, if approved, these third-party payors are increasingly challenging the price and examining 
the cost-effectiveness of medical products and services, with a recent focus on prioritization of “equivalent,” less expensive 
alternatives when available. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare 
products. We may need to conduct expensive clinical studies to demonstrate the comparative cost-effectiveness of our products. The 
product candidates that we develop may not be considered cost-effective. It is time consuming and expensive for us to seek coverage 
and reimbursement from third-party payors. Moreover, a payor’s decision to provide coverage for a drug product does not imply that 
an adequate reimbursement rate will be approved, especially for product candidates such as ours, which are used in the inpatient 
setting, usually resulting in no separate reimbursement for pharmaceuticals. There are additional pressures on pricing as a result of 
other, peripheral policies impacting reimbursement across both government and private payors. Non-health specific policies may 
impart downstream impacts on private insurance reimbursement decision-making. In consideration of these numerous factors, 
reimbursement may not be available or sufficient to allow us to sell our products on a competitive and profitable basis. 

Medicare is a federally-funded program managed by CMS through local contractors that administer coverage and 
reimbursement for certain healthcare items and services furnished to the elderly and disabled. Medicare Part A covers inpatient 
hospitalization and Medicare Part B covers outpatient medical services. Medicare coverage of drugs and biological products and 
payment rates to providers are established by federal law and regulations. Medicaid is an insurance program for certain categories of 
low income patients who are otherwise uninsured and is both federally and state funded and managed by each state. The federal 
government sets general guidelines for Medicaid and requires rebates on outpatient drugs and biological products, including those 
administered by physicians if the cost is billed separately. Each state creates specific regulations that govern its individual program, 
including supplemental rebate programs that prioritize coverage for drugs on the state Preferred Drug List. Government laws and 
regulations also establish price controls on prescription drugs purchased by government agencies that provide health care and certain 
federally funded hospital outpatient departments and clinics. In the U.S., private health insurers and other third-party payors often 
provide reimbursement for products and services based on the level at which the government provides reimbursement through the 
Medicare or Medicaid programs for such products and services. These restrictions and limitations influence the purchase of healthcare 
services and products. In addition, government programs like Medicaid include substantial penalties for increasing commercial prices 
over the rate of inflation which can affect realization and return on investment. Further, some stakeholders have recently questioned 
whether the market price of prescription drugs may be inflated by virtue of the built-in cost imparted by the government rebate model, 
often negotiated indirectly in exchange for a coverage determination or formulary placement where relevant. 

In the U.S., the European Union, and other potentially significant markets for our product candidates, government authorities 
and private third-party payors are increasingly attempting to limit or regulate the price of medical products and services, particularly 
for new and innovative products and therapies, which often has resulted in average selling prices lower than they would otherwise be. 
Manufacturers frequently must rebate a portion of the prescription price to the third‑party payors as a condition of coverage, which 
can greatly reduce realization on the sale. Third-party payors are increasingly challenging the price and examining the medical 
necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy, and are developing 
increasingly sophisticated methods of controlling healthcare costs. They may limit coverage to specific drug products on an approved 

36 

list, or formulary, which might not include all the FDA-approved drug products for a particular indication, or they may control costs, 
particularly for new expensive therapies, by requiring prior authorization or imposing other restrictions before covering certain 
products, or they may condition payment based on achieving performance metrics. Legislative proposals to reform healthcare or 
reduce costs under government programs may result in lower reimbursement for our product candidates or exclusion of our product 
candidates from coverage. 

Achieving favorable CMS coverage and reimbursement is usually a significant gating issue for successful introduction of a new 
product, because Medicare and Medicaid can represent a sizeable share of the market and because private payors often rely on the lead 
of the governmental payors in rendering coverage and reimbursement determinations. Further, the increased emphasis on managed 
healthcare in the U.S. and on country and regional pricing and reimbursement controls in the European Union will likely put 
additional pressure on product pricing, reimbursement, and utilization, which may adversely affect our future product sales and results 
of operations. These pressures can arise from rules and practices of managed care groups, competition within therapeutic classes, 
availability of generic equivalents, judicial decisions and governmental laws and regulations related to Medicare, Medicaid, and 
healthcare reform, pharmaceutical coverage and reimbursement policies, and pricing in general. Patients who are prescribed 
treatments 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. Sales of our product candidates will therefore depend substantially, both domestically and 
abroad, on the extent to which the costs of our products will be paid by health maintenance, managed care, pharmacy benefit and 
similar healthcare management organizations, or reimbursed by government health administration authorities, such as Medicare and 
Medicaid, private health insurers, and other third-party payors.  

As a result of the above, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical 
necessity and cost-effectiveness of our products, in addition to the costs required to obtain FDA approvals. Our product candidates 
may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a drug product does not 
imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to ensure 
acceptance and use of our products and product candidates or enable us to maintain price levels sufficient to realize an appropriate 
return on our investment in drug development. Legislative and regulatory proposals to reform healthcare or reduce costs under 
government insurance programs may result in lower reimbursement for our products and product candidates or exclusion of our 
products and product candidates from coverage. The cost containment measures that healthcare payors and providers are instituting 
and any healthcare reform could significantly reduce our revenues from the sale of any approved product candidates. We cannot 
provide any assurances that we will be able to obtain and maintain third-party coverage or adequate reimbursement for our product 
candidates in whole or in part. 

Healthcare Reform 

The U.S. and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to 

change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in 
the U.S. and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing 
healthcare costs, improving quality and/or expanding access. In the U.S., the pharmaceutical industry has been a particular focus of 
these efforts and has been significantly affected by major federal and state legislative initiatives. 

In addition, other legislative and regulatory changes have been proposed and adopted since the ACA was enacted. These 

changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in 2013, which will 
remain in effect through 2025 unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 
2012, which, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment 
centers, increased the statute of limitations period for the government to recover overpayments to providers from three to five years. In 
2017, CMS promulgated a rule reducing Medicare Part B reimbursement to hospitals for drugs purchased under the 340B program by 
30%. Although hospital trade associations filed a lawsuit challenging the regulation, the final rule is now in effect.  

In recent years, there have been and continue to be proposals by the federal government, state governments, regulators, and 

third-party payors to control these costs and, more generally, to reform the U.S. health care system. Certain of these proposals could 
limit the prices we are able to charge for our products or the amounts of reimbursement available for our products. These laws and 
future laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect 
on customers for our product candidates, if approved, and, accordingly, our financial operations. 

37 

Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in 

payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from 
being able to generate revenue, attain profitability or commercialize our drugs. 

The cost of pharmaceuticals continues to generate substantial governmental and third-party payor interest and states have begun 

to take action to increase transparency in drug pricing through mandatory reporting requirements. We expect that the pharmaceutical 
industry will experience pricing pressures due to the trend toward managed healthcare, the increasing influence of managed care 
organizations, and additional legislative proposals. Our results of operations could be adversely affected by current and future 
healthcare reforms. While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise 
implemented in the future, the announcement or adoption of these proposals could have a material adverse effect on our ability to 
obtain adequate prices for our product candidates and operate profitably. 

Foreign Regulation 

In addition to regulations in the U.S., we will be subject to a variety of foreign regulations governing clinical trials and 

commercial sales and distribution of our products to the extent we choose to develop or sell any products outside of the U.S. The 
approval process varies from country to country and the time may be longer or shorter than that required to obtain FDA approval. The 
requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to 
country. 

In the EU and the United Kingdom, member states require both regulatory clearances by the national competent authority and a 

favorable ethics committee opinion prior to the commencement of a clinical trial. Under the EU regulatory systems, marketing 
authorization applications may be submitted under either a centralized or decentralized procedure. The centralized procedure provides 
for the grant of a single marketing authorization that is valid for all EU member states. It is compulsory for medicines produced by 
certain biotechnological processes. Because our products are produced in that way, we would be subject to the centralized process. 
Under the centralized procedure, pharmaceutical companies submit a single marketing authorization application to the European 
Medicines Agency. Once granted by the European Commission, a centralized marketing authorization is valid in all EU member 
states, as well as the European Economic Area countries. By law, a company can only start to market a medicine once it has received a 
marketing authorization. 

Employees and Human Capital Management 

As of December 31, 2021, we had 319 employees, 242 of whom were engaged in research and development activities and 77 of 

whom were engaged in general and administrative support activities. None of our employees are subject to a collective bargaining 
agreement. Our employees are highly skilled, and many hold advanced degrees. Most of our employees have experience with the 
development of cell therapies. We consider our relationship with our employees to be good. Our future performance depends 
significantly upon the continued service of our key scientific, technical and senior management personnel and our continued ability to 
attract and retain highly skilled employees. We provide our employees with competitive salaries and bonuses, opportunities for equity 
ownership, development programs that enable continued learning and growth and a robust employment package that promotes well-
being across all aspects of their lives. In addition to salaries, these programs include potential annual discretionary bonuses, stock 
awards, a 401(k) plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, 
and flexible work schedules, among other benefits. We have taken proactive, aggressive action throughout the COVID-19 pandemic to 
protect the health and safety of our employees. We expect to continue to implement these measures until we determine that the 
COVID-19 pandemic is adequately contained for purposes of our business. We may take further actions, in compliance with all 
appropriate government regulations, that we determine to be in the best interest of our employees.

Item 1A.          Risk Factors  

The risks described below may not be the only ones relating to our company. Additional risks that we currently believe are 

immaterial may also impair our business operations. Our business, financial conditions and future prospects and the trading price of 
our common stock could be harmed as a result of any of these risks. Investors should also refer to the other information contained or 
incorporated by reference in this Annual Report on Form 10-K, including our financial statements and related notes, and our other 
filings from time to time with the Securities and Exchange Commission, or SEC. 

Risk Factors Summary  

Our business is subject to a number of risks and uncertainties, including those risks discussed at length below. These risks 
include, among others, the brief bulleted list of our principal risk factors set forth below that make an investment in our company 
speculative or risky. You are encouraged to carefully review our full discussion of the material risk factors relevant to an investment in 
our business, which follows the brief bulleted list of our principal risk factors set forth below. 

•  We are substantially dependent on the success of our product candidates and cannot guarantee that these product candidates 

will successfully complete development, receive regulatory approval, or be successfully commercialized; 

•  We may encounter substantial delays in our clinical trials or may not be able to conduct our trials on the timelines we expect 
and we may be required to conduct additional clinical trials or modify current or future clinical trials based on feedback we 
receive from the FDA; 
It may take longer and cost more to complete our clinical trials than we project, or we may not be able to complete them at 
all; 

• 

•  Our clinical trials may fail to demonstrate adequately the safety and efficacy of our product candidates, which would prevent 

or delay regulatory approval and commercialization; 

•  The manufacture of our product candidates is complex, and we may encounter difficulties in production, particularly with 
respect to process development, quality control, or scaling-up of our manufacturing capabilities. If we, or any of our third-
party manufacturers encounter such difficulties, our ability to provide supply of our product candidates for clinical trials or 
our products for patients, if approved, could be delayed or stopped, or we may be unable to maintain a commercially viable 
cost structure; 

•  Cell-based therapies and biologics rely on the availability of reagents, specialized equipment, and other specialty materials, 
which may not be available to us on acceptable terms or at all. For some of these reagents, equipment, and materials, we rely 
or may rely on sole source vendors or a limited number of vendors, which could impair our ability to manufacture and supply 
our products; 

•  We collaborate with governmental, academic and corporate partners to improve and develop TIL therapies for new 

indications for use in combination with other therapies and to evaluate new TIL manufacturing methods, the results of which, 
because the manufacturing processes are not within our control, may be incorrect or unreliable; 

•  We may need additional financing to fund our operations and complete the development and commercialization of our 

various product candidates, and if we are unable to obtain such financing, we may be unable to complete the development 
and commercialization of our product candidates. Raising additional capital may cause dilution to our existing stockholders, 
restrict our operations or require us to relinquish rights to our technologies or product candidates; 

•  We are subject to extensive regulation, which can be costly, time consuming and can subject us to unanticipated delays; even 

if we obtain regulatory approval for some of our products, those products may still face regulatory difficulties; 

•  We are required to pay substantial royalties and lump sum benchmark payments under our license agreements with the NIH, 

Moffitt, Novartis, and Cellectis, and we must meet certain milestones to maintain our license rights; 

•  Because our current products represent, and our other potential product candidates will represent novel approaches to the 

treatment of disease, there are many uncertainties regarding the development, the market acceptance, third-party 
reimbursement coverage and the commercial potential of our product candidates; 

•  No assurance can be given that the Gen 2 manufacturing process we have selected will be FDA-compliant, more efficient and 

lower the cost to manufacture TIL products; 

•  We face significant competition from other biotechnology and pharmaceutical companies and from non-profit institutions; 
•  Development of a product candidate intended for use in combination with an already approved product may present more or 

different challenges than development of a product candidate for use as a single agent; 

39 

 
 
•  A Fast Track product designation, Breakthrough Therapy designation or other designation to facilitate product candidate 

development may not lead to faster development or a faster regulatory review or approval process, and it does not increase 
the likelihood that our product candidates will receive marketing approval; 

•  While lifileucel has received Orphan Drug Designation, or ODD, for melanoma stages IIB-IV and for cervical cancer 

patients with tumors greater than 2 cm, there is no guarantee that we will be able to maintain this designation, receive these 
designations for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of 
exclusivity; 

•  As a condition of approval, the FDA may require that we implement various post-marketing requirements and conduct post-
marketing studies, any of which would require a substantial investment of time, effort, and money, and which may limit our 
commercial prospects; 

•  We may be unable to establish effective marketing and sales capabilities or enter into agreements with third parties to market 
and sell our product candidates, if they are approved, and as a result, we may be unable to generate product revenues; 
If our product candidates do not achieve broad market acceptance, the revenues that we generate from their sales will be 
limited; 

• 

•  Our business could be adversely affected by the effects of health epidemics, including the recent spread of the COVID-19 

pandemic, in regions where we or third parties on which we rely have significant manufacturing facilities, concentrations of 
clinical trial sites or other business operations. The COVID-19 pandemic could materially affect our operations, including at 
our headquarters in San Carlos, California and at our manufacturing facility in Philadelphia, Pennsylvania, which are 
currently subject to state executive orders and shelter-in-place orders, and at our clinical trial sites, as well as the business 
or operations of our other manufacturers, CROs or other third parties with whom we conduct business; 

•  We will need to grow the size and capabilities of our organization, and we may experience difficulties in managing this 

growth; 

•  We may rely on third parties to perform many essential services for any products that we commercialize, including services 
related to distribution, government price reporting, customer service, accounts receivable management, cash collection, and 
adverse event reporting. If these third parties fail to perform as expected or to comply with legal and regulatory 
requirements, our ability to commercialize our current or future product candidates will be significantly impacted and we 
may be subject to regulatory sanctions; 

•  The FDA regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the 

clinical development and regulatory approval of our product candidates; 

•  Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be 

successful in obtaining regulatory approval of our product candidates in other jurisdictions; 

•  Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, which 

could make it difficult for us to sell our product candidates profitably; and 

•  Governments outside the U.S. tend to impose strict price controls, which may adversely affect our revenues, if any. 

Risks Related to Our Business 

We have a history of operating losses; we expect to continue to incur losses and we may never be profitable. 

We are a clinical-stage biotechnology company focused on the development and commercialization of novel cancer 

immunotherapy products designed to harness the power of a patient's own immune system to eradicate cancer. We do not have 
products approved for commercial sale and have not generated revenue from operations. As of December 31, 2021, we had an 
accumulated deficit of $1.2 billion. In addition, during the year ended December 31, 2021, we incurred a net loss of $342.3 million. 
Since our inception we have not generated any revenues from operations. We are preparing for the commercial launch of our products, 
if approved, in 2022. We do not expect to generate any meaningful product sales or royalty revenues until we have a product 
approved. We expect to incur significant additional operating losses in the future as we expand our development and clinical trial 
activities in support of demonstrating the effectiveness of our products. 

Our ability to achieve long-term profitability is dependent upon obtaining regulatory approvals for our products and 
successfully commercializing our products alone or with third parties. However, our operations may not be profitable even if any of 
our products under development are successfully developed and produced and thereafter commercialized. 

40 

 
Our current line of business, and the biotechnology industry in which we operate, makes it difficult to evaluate our business 

plan and our prospects. 

We have only a limited operating history in our current line of business on which a decision to invest in our company can be 

based. The future of our company currently is dependent upon our ability to implement our business plan, as that business plan may be 
modified from time to time by our management and Board of Directors. While we believe that we have a reasonable business plan and 
research and development strategy, we have only a limited operating history against which we can test our plans and assumptions, and 
investors therefore cannot evaluate the likelihood of our success. 

We face the problems, expenses, difficulties, complications and delays normally associated with a pre-commercial 

biotechnology company, many of which are beyond our control. Accordingly, our prospects should be considered in light of the risks, 
expenses and difficulties frequently encountered in the establishment of a new business developing technologies in an industry that is 
characterized by a number of market entrants and intense competition. Because of our size and limited resources, we may not possess 
the ability to successfully overcome many of the risks and uncertainties frequently encountered by pre-commercial companies 
involved in the rapidly evolving field of immunotherapy. If our research and development efforts are successful, we may also face the 
risks associated with the shift from development to commercialization of new products based on innovative technologies. There can 
be no assurance that we will be successful in developing our business. 

We are substantially dependent on the success of our product candidates and cannot guarantee that these product 

candidates will successfully complete development, receive regulatory approval, or be successfully commercialized. 

We currently have no products approved for commercial sale. We have invested a significant portion of our efforts and 
financial resources in the development of our current product candidates, including lifileucel, LN-145, IOV-2001, and IOV-3001, and 
expect that we will continue to invest heavily in our current product candidates, as well as in any future product candidates we may 
develop. Our business depends entirely on the successful development and commercialization of our product candidates, which may 
never occur. Our ability to generate revenues in the future is substantially dependent on our ability to develop, obtain regulatory 
approval for, and then successfully commercialize our product candidates. We currently generate no revenue from the sale of any 
products, and we may never be able to develop or commercialize a marketable product. 

Our product candidates will require additional clinical and non-clinical development, regulatory approval, commercial 
manufacturing arrangements, establishment of a commercial organization, significant marketing efforts, and further investment before 
we generate any revenue from product sales. We cannot assure you that we will meet our timelines for our current or future clinical 
trials, which may be delayed or not completed for a number of reasons, including the negative impact of the COVID-19 pandemic. 

We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA 
or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates or 
regulatory approval that will allow us to successfully commercialize our product candidates. If we do not receive FDA approval with 
the necessary conditions to allow successful commercialization, and then successfully commercialize our product candidates, we will 
not be able to generate revenue from those product candidates in the U.S. in the foreseeable future, or at all. Any significant delays in 
obtaining approval for and commercializing our product candidates will have a material adverse impact on our business and financial 
condition. 

We have not previously submitted a BLA to the FDA, or similar marketing application to comparable foreign authorities, for 

any product candidate, and we cannot be certain that our current or any future product candidates will be successful in clinical trials or 
receive regulatory approval. Furthermore, although we do not expect to submit our BLA with comparisons to existing or more 
established therapies and likewise do not expect the FDA to base its determination with respect to product approval on such 
comparisons, the FDA may factor these comparisons into its decision whether to approve our TIL therapies, including lifileucel for 
metastatic melanoma and metastatic cervical cancer. The FDA may also consider its approvals of competing products, which may 
alter the treatment landscape concurrently with their review of our BLA filings, and which may lead to changes in the FDA’s review 
requirements that have been previously communicated to us and our interpretation thereof, including changes to requirements for 
clinical data or clinical study design. Such changes could delay approval or necessitate withdrawal of our BLA filings. 

Our product candidates are susceptible to the risks of failure inherent at any stage of product development, including the 
appearance of unexpected adverse events or failure to achieve primary endpoints in clinical trials. Further, our product candidates may 
not receive regulatory approval even if they are successful in clinical trials. 

41 

If approved for marketing by applicable regulatory authorities, our ability to generate revenues from our product candidates will 

depend on our ability to: 

• 

• 
• 

• 

price our product candidates competitively such that third-party and government reimbursement leads to broad product 
adoption; 
prepare a broad network of clinical sites for administration of our product; 
create market demand for our product candidates through our own marketing and sales activities, and any other 
arrangements to promote these product candidates that we may otherwise establish; 
receive regulatory approval for the targeted patient population(s) and claims that are necessary or desirable for successful 
marketing; 
effectively commercialize our products; 

• 
•  manufacture product candidates through CMOs or in our own manufacturing facility in sufficient quantities and at 

• 

acceptable quality and manufacturing cost to meet commercial demand at launch and thereafter; 
establish and maintain agreements with wholesalers, distributors, pharmacies, and group purchasing organizations on 
commercially reasonable terms; 

•  maintain patent and trade secret protection and regulatory exclusivity for our product candidates; 
• 
•  maintain compliance with applicable laws, regulations, and guidance specific to commercialization including interactions 

launch commercial sales of our product candidates; 

with health care professionals, patient advocacy groups, and communication of health care economic information to payors 
and formularies; 
achieve market acceptance of our product candidates by patients, the medical community, and third-party payors; 
achieve appropriate reimbursement for our product candidates; 

• 
• 
•  maintain a distribution and logistics network capable of product storage within our specifications and regulatory guidelines, 

and further capable of timely product delivery to commercial clinical sites; 
effectively compete with other therapies or competitors; and 
following launch, assure that our product will be used as directed and that additional unexpected safety risks will not arise. 

• 
• 

We may face risks due to the need to rely on third parties, including clinical trial sites. 

We are heavily reliant on third parties to conduct our clinical trials. We have a limited history of conducting clinical trials and 
have no experience as a company in filing and supporting the applications necessary to gain marketing approvals. Securing marketing 
approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for 
each therapeutic indication to establish the product candidate’s safety, purity, and potency for that indication. Securing marketing 
approval also requires the submission of information about the product manufacturing process to, and inspection of manufacturing 
facilities and clinical trial sites by, applicable regulatory authorities. Clinical testing is expensive and can take many years to complete, 
and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. As a result of the COVID-19 
pandemic, institutions and research sites that currently conduct clinical trials may not be able to return to normal clinical trial 
operations for some time, or may no longer choose to participate in studies in the future. Furthermore, clinical trials may be delayed or 
otherwise may be more difficult to execute in the future. 

We have recruited a team that has experience with clinical trials and in the development of preclinical assets for translation into 

clinical trials; however, we as a company have limited experience completing pivotal clinical trials for cell therapy products or 
developing preclinical immunotherapy products. In part because of this lack of experience, we cannot be certain that our ongoing 
pivotal clinical trials will be completed on time, if at all, will progress according to our plans or expectations, or that our planned 
clinical trials will be initiated or initiated in a timely manner, progress according to our plans or expectations, or be completed on time, 
if they are completed at all. 

Large-scale clinical trials require significant financial and management resources, and reliance on third-party clinical 
investigators, Contract Research Organizations, or CROs, Contract Manufacturing Organizations, or CMOs, or consultants. Relying 
on third-party clinical investigators, CROs or CMOs may force us to encounter delays and challenges that are outside of our control. 
We rely on CMOs in the U.S. and Europe to manufacture TIL for use in our trials. We may not be able to demonstrate sufficient 
comparability between products manufactured at different facilities to allow for inclusion of the clinical results from patients treated 
with products from these different facilities, or with our own manufacturing facility, in our product registrations. Further, our CMOs 
may not be able to manufacture TIL or otherwise fulfill their obligations to us because of interruptions to their business, including the 
loss of their key staff or interruptions to their raw material supply. 

42 

 
We rely on third party CROs and clinical trial sites to conduct, supervise, and monitor our clinical trials for our product 
candidates. We expect to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions, 
independent review organizations and clinical investigators, to conduct our clinical trials. While we have agreements governing their 
activities, we have limited influence over their actual performance and control only certain aspects of their activities. The failure of 
these third parties to successfully carry out their contractual duties or meet expected deadlines could substantially harm our business 
because we may be delayed in completing or unable to complete the clinical trials required to support future approval of our product 
candidates, or we may not obtain marketing approval for or commercialize our product candidates in a timely manner or at all. 
Moreover, these agreements might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to 
enter into alternative arrangements, that could delay our product development activities and adversely affect our business. 

Our reliance on these third parties for development activities will reduce our control over these activities. Nevertheless, we are 

responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory, and 
scientific standards and our reliance on the CROs, clinical trial sites, and other third parties does not relieve us of these oversight 
responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with 
the general investigational plan and protocols for the trial and for ensuring that our preclinical trials are conducted in accordance with 
Good Laboratory Practices, or GLPs, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us to 
comply with GCPs for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are 
credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Regulatory authorities enforce 
these requirements through periodic inspections (including pre-approval inspections once a BLA is filed with the FDA) of trial 
sponsors, clinical investigators, trial sites and certain third parties including CMOs. If we, our CROs, clinical trial sites, or other third 
parties fail to comply with Good Clinical Practices, or applicable GCPs, or other regulatory requirements, we or they may be subject 
to enforcement or other legal actions, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or 
comparable foreign regulatory authorities may require us to perform additional clinical trials. We cannot assure you that upon 
inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP 
regulations. 

In addition, we will be required to report certain financial interests of our third-party investigators if these relationships exceed 
certain financial thresholds or meet other criteria. The FDA or comparable foreign regulatory authorities may question the integrity of 
the data from those clinical trials conducted by investigators that are determined to have conflicts of interest. 

In addition, our clinical trials must be conducted with product candidates that were produced under cGMP regulations. Our 
failure to comply or our CMOs’ failure to comply with these regulations may require us to repeat clinical trials, which would delay the 
regulatory approval process. We also are required to register certain clinical trials and post the results of certain completed clinical 
trials on a government sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so could result in 
enforcement actions and adverse publicity. 

Our CROs, clinical trial sites, and other third parties may also have relationships with other entities, some of which may be our 

competitors, for whom they may also be conducting clinical trials or other therapeutic development activities that could harm our 
competitive position. In addition, these third parties are not our employees, and except for remedies available to us under our 
agreements with them, we cannot control whether or not they devote sufficient time and resources to our ongoing clinical, non-
clinical, and preclinical programs. If these third parties do not successfully carry out their contractual duties, meet expected deadlines 
or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, 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 our protocols, regulatory requirements or for 
other reasons, our trials may be repeated, extended, delayed, or terminated and we may not be able to obtain, or may be delayed in 
obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully 
commercialize our product candidates, or we or they may be subject to regulatory enforcement actions. As a result, our results of 
operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to 
generate revenues could be delayed. To the extent we are unable to successfully identify and manage the performance of third party 
service providers in the future, our business may be materially and adversely affected. 

If any of our relationships with these third parties terminate, we may not be able to enter into alternative arrangements or do so 
on commercially reasonable terms. Switching or adding additional contractors involves additional cost and requires management time 
and focus. In addition, there is a natural transition period when a new third party commences work. As a result, delays could occur, 
which could compromise our ability to meet our desired development timelines. Though we carefully manage our relationships with 
our third-party service providers, there can be no assurance that we will not encounter similar challenges or delays in the future or that 

43 

these delays or challenges will not have a material adverse impact on our business, financial condition and prospects or results of 
operations. 

We also rely on other third parties to manufacture and ship our products for the clinical trials that we conduct. Any performance 

failure on the part of these third parties could delay clinical development or marketing approval of our product candidates or any 
additional product candidates or commercialization of our product candidates, if approved, producing additional losses and depriving 
us of potential product revenue. 

We may encounter substantial delays in our clinical trials or may not be able to conduct our trials on the timelines we expect 
and we may be required to conduct additional clinical trials or modify current or future clinical trials based on feedback we receive 
from the FDA. 

Clinical testing is expensive, time consuming, and subject to uncertainty. We cannot guarantee that any current or future 

clinical studies will be conducted as planned or completed on schedule, if at all, or that any of our product candidates will receive 
regulatory approval. We initiated clinical trials in patients with metastatic melanoma, cervical, head and neck and non-small cell lung 
cancers, and in other indications in collaboration with third parties. We have completed enrollment in the pivotal clinical trial for 
melanoma, C-144-01. In May 2020, we disclosed interim results for Cohort 4 of the C-144-01 clinical trial. The interim results speak 
only to data available as of March 16, 2020, and although such data have been reviewed by the investigators, they have not been 
reviewed by an IRC. In addition, differences in patient population may affect the clinical results of Cohort 4 as compared to Cohort 2. 
We plan to initiate trials in new indications, and new cohorts in existing trials. Even as these trials progress, issues may arise that 
could require us to suspend or terminate such clinical trials or could cause the results of one cohort to differ from a prior cohort. For 
example, we may experience slower than anticipated enrollment in our pivotal clinical trials, which may consequently delay our BLA 
filing timelines or permit competitors to obtain approvals that may alter our BLA filing strategy. A failure of one or more clinical 
studies can occur at any stage of testing, and our future clinical studies may not be successful. Events that may prevent successful or 
timely initiation or completion of clinical development, or product approval include: 

• 

• 
• 

• 

• 

• 

• 
• 

• 
• 
• 

• 

• 

regulators or IRBs may not authorize us or our investigators to commence a clinical trial, conduct a clinical trial at a 
prospective trial site, or amend trial protocols, or regulators or IRBs may require that we modify or amend our clinical trial 
protocols; 
delays in reaching a consensus or inability to obtain agreement with regulatory agencies on study design; 
the FDA or comparable foreign regulatory authorities may disagree with our intended indications, study design or our 
interpretation of data from preclinical studies and clinical trials or find that a product candidate’s benefits do not outweigh 
its safety risks; 
the FDA or comparable foreign regulatory authorities may not accept data from studies with clinical trial sites in foreign 
countries; 
the FDA may not allow us to use the clinical trial data from a research institution to support an IND if we cannot 
demonstrate the comparability of our product candidates with the product candidate used by the relevant research 
institution in its clinical studies; 
delays in or failure to reach an agreement on acceptable terms with prospective CROs and clinical study sites, the terms of 
which can be subject to extensive negotiation and may vary significantly among different CROs and clinical study sites; 
delays in obtaining required IRB approval at each clinical study site; 
imposition of a temporary or permanent clinical hold, suspensions or terminations by regulatory agencies, IRBs, or us for 
various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed 
to unacceptable health risks, undesirable side effects, or other unexpected characteristics of the product candidate, or due to 
findings of undesirable effects caused by a biologically or mechanistically similar therapeutic or therapeutic candidate; 
delays in recruiting suitable patients to participate in our clinical studies; 
delay in adding new investigators or clinical trial sites, or withdrawal of clinical trial sites from a study; 
delay or change in strategic direction for an indication resulting from differences in results between cohorts in a clinical 
trial, such as Cohort 2 and Cohort 4 of the C-144-01 clinical trial or the previously disclosed preliminary results for the C-
145-04 trial and the final patient population and results, including differences in patient population, such as differences that 
might arise due to the impact of the existing immunotherapy treatment landscape, or from different interpretations of 
investigator results by IRC; 
failure by our CROs, clinical trial sites, patients, or other third parties, or us to adhere to clinical study requirements, 
including regulatory, contractual or protocol requirements; 
failure to perform in accordance with the FDA’s cGCP requirements, or applicable regulatory guidelines in other countries;

the number of patients required for clinical trials of our product candidates may be larger than we anticipate or enrollment 
in these clinical trials may be slower than we anticipate, potentially affecting our timelines for approval of our product 
candidates; 
patients that enroll in our studies may misrepresent their eligibility or may otherwise not comply with the clinical trial 
protocol, resulting in the need to drop such patients from the study or clinical trial, increase the needed enrollment size for

transfer of our manufacturing processes to our CMOs or other larger-scale facilities operated by a CMO or by us and 
delays or failure by our CMOs or us to make any necessary changes to such manufacturing process; 
our use of different manufacturing processes within our clinical trials, including our Gen 1 and Gen 2 manufacturing 
processes, and any effects that may result from the use of different processes on the clinical data that we have reported and 
will report in the future; and 
delays in manufacturing, testing, releasing, validating, or importing/exporting sufficient stable quantities of our product 
candidates for use in clinical studies or the inability to do any of the foregoing, including as a result of any quality issues 
associated with the contract manufacturer. 

We also may conduct clinical and preclinical research in collaboration with other academic, pharmaceutical, biotechnology and 

biologics entities in which we combine our technologies with those of our collaborators. Such collaborations may be subject to 
additional delays because of the management of the trials, contract negotiations, the need to obtain agreement from multiple parties, 
and the necessity of obtaining additional approvals for therapeutics used in the combination trials. These combination therapies will 
require additional testing and clinical trials will require additional FDA regulatory approval and will increase our future cost of 
expenses. 

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our 
ability to generate revenue. In addition, if we make manufacturing changes to our product candidates, we may be required to, or we 
may elect to, conduct additional studies to bridge our modified product candidates to earlier versions. These changes may require FDA 
approval or notification, may not have their desired effect, or the FDA may not accept data from prior versions of the product to 
support an application, delaying our clinical trials or programs or necessitating additional clinical or preclinical studies. For example, 
while we currently intend to file our first BLA using our Gen 2 manufacturing process, in the future we may seek to commercialize 

45 

other manufacturing processes, such as our Gen 3 manufacturing process or our PD-1 selected TIL manufacturing process. We may 
find that commercialization of these manufacturing processes has unintended consequences that necessitate additional development 
and manufacturing work or additional clinical and preclinical studies, or results in a refusal to file or non-approval of a BLA. 

Clinical study delays could shorten any periods during which our products have patent protection and may allow our 
competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product 
candidates and may harm our business and results of operations. 

Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may 

decide that our data are insufficient for approval and require additional preclinical, clinical or other studies. The number and types of 
preclinical studies and clinical trials that will be required for regulatory approval also varies depending on the product candidate, the 
disease or condition that the product candidate is designed to address, and the regulations applicable to any particular product 
candidate. Approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the 
course of a product candidate’s clinical development and may vary among jurisdictions. It is possible that any product candidates we 
may seek to develop in the future will never obtain the appropriate regulatory approvals necessary for us or any future collaborators to 
commence product sales. Any delay in completing development, obtaining or failure to obtain required approvals could also 
materially adversely affect our ability or that of any of our collaborators to generate revenue from any such product candidate, which 
likely would result in significant harm to our financial position and adversely impact our stock price. 

It may take longer and cost more to complete our clinical trials than we project, or we may not be able to complete them at 

all. 

For budgeting and planning purposes, we have projected the date for the commencement of future trials, and continuation and 

completion of our ongoing clinical trials. However, a number of factors, including scheduling conflicts with participating clinicians 
and clinical institutions, difficulties in identifying and enrolling patients who meet trial eligibility criteria, and the ongoing COVID-19 
pandemic, may cause significant delays. We may not commence or complete clinical trials involving any of our products as projected 
or may not conduct them successfully. 

We are currently enrolling six company-sponsored clinical trials to assess the overall safety and efficacy of Iovance TIL 

monotherapy and TIL combinations in patients with melanoma, cervical, head and neck and lung cancers across late-line and early 
treatment settings, as well as our peripheral blood lymphocyte, or PBL, technology for hematological malignancies. However, we may 
experience difficulties in patient enrollment in our clinical trials for a variety of reasons. Our ability to enroll or treat patients in our 
other studies, or the duration or costs of those studies, could be affected by multiple factors, including, preliminary clinical results, 
which may include efficacy and safety results from our ongoing Phase 2 studies, but may not be reflected in the final analyses of these 
trials. For example, our studies of our TIL therapy lifileucel in patients with metastatic cervical cancer and metastatic melanoma 
utilize an “open-label” trial design. An open-label trial is one where both the patient and investigator know whether the patient is 
receiving the test article or either an existing approved drug or placebo, which has the potential to create selection bias in the 
investigators. In our Phase 2 open-label studies of TIL therapy lifileucel in patients with metastatic cervical cancer and metastatic 
melanoma, the investigators have significant discretion over the selection of patient participants. Although preliminary data from these 
trials was generally positive, that data may not necessarily be representative of interim or final results, as new patients are cycled 
through the applicable treatment regimes. As the trials continue, the investigators may prioritize patients with more progressed forms 
of cancer than the initial patient population, based on the success or perceived success of that initial population. Patients with more 
progressed forms of cancer may be less responsive to treatment, and accordingly, interim efficacy data may show a decline in patient 
response rate or other assessment metrics. As the trials continue, investigators may shift their approach to the patient population, 
which may ultimately result in a decline in both interim and final efficacy data from the preliminary data, or conversely, an increase in 
final efficacy data following a decline in the interim efficacy data, as patients with more progressed forms of cancer are cycled out of 
the trials and replaced by patients with less advanced forms of cancer. This opportunity for investigator selection bias in our trials as a 
result of open-label design may not be adequately handled and may cause a decline in or distortion of clinical trial data from our 
preliminary results. Depending on the outcome of our open-label studies, we may need to conduct one or more follow-up or 
supporting studies in order to successfully develop our products for FDA approval. Many companies in the biotechnology, 
pharmaceutical and medical device industries have suffered significant setbacks in late-stage clinical trials after achieving positive 
results in earlier development, and we cannot be certain that we will not face such setbacks. 

Furthermore, the timely completion of clinical trials in accordance with their protocols depends, among other things, on our 

ability to enroll a sufficient number of patients who remain in the study until its conclusion, including the ability of us or our 
collaborators to conduct clinical trials under the constraints of the COVID-19 pandemic. In addition, our clinical trials will compete 

46 

with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition 
will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may 
instead opt to enroll in a trial being conducted by one of our competitors. Accordingly, we cannot guarantee that the trial will progress 
as planned or as scheduled. Delays in patient enrollment may result in increased costs or may affect the timing or outcome of our 
ongoing clinical trial and planned clinical trials, which could prevent completion of these trials and adversely affect our ability to 
advance the development of our product candidates. 

We expect to rely on medical institutions, academic institutions or CROs to conduct, supervise or monitor some or all aspects 
of clinical trials involving our products. We will have less control over the timing and other aspects of these clinical trials than if we 
conducted them entirely on our own. If we fail to commence or complete, or experience delays in, any of our planned clinical trials, 
our stock price and our ability to conduct our business as currently planned could be harmed. 

We currently anticipate that we will have to rely on our CMOs to manufacture our adoptive cell therapy and biologic products 

for clinical trials. If they fail to commence or complete, or experiences delays in, manufacturing our adoptive cell therapy and other 
biologic products, our planned clinical trials will be delayed, which will adversely affect our stock price and our ability to conduct our 
business as currently planned. 

Clinical trials are expensive, time-consuming and difficult to design and implement, and our clinical trial costs may be 

higher than for more conventional therapeutic technologies or drug products. 

Clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory 
requirements. Because our product candidates include candidates based on new cell therapy technologies and manufactured on a 
patient-by-patient basis, we expect that they will require extensive research and development and have substantial manufacturing 
costs. In addition, costs to treat patients with relapsed/refractory cancer and to treat potential side effects that may result from our 
product candidates can be significant. Some clinical trial sites may not bill, or obtain coverage from Medicare, Medicaid, or other 
third-party payors for some or all of these costs for patients enrolled in our clinical trials, and we may be required by those trial sites to 
pay such costs. Accordingly, our clinical trial costs are likely to be significantly higher per patient than those of more conventional 
therapeutic technologies or drug products. In addition, our proposed personalized product candidates involve several complex and 
costly manufacturing and processing steps, the costs of which will be borne by us. We are also responsible for the manufacturing costs 
of products for patients that may have a tumor resection but ultimately do not receive an infusion. Depending on the number of 
patients that we ultimately screen and enroll in our trials, and the number of trials that we may need to conduct, our overall clinical 
trial costs may be higher than for more conventional treatments. 

Our clinical trials may fail to demonstrate adequately the safety and efficacy of our product candidates, which would 

prevent or delay regulatory approval and commercialization. 

The clinical trials of our product candidates are, and the manufacturing and marketing of our products will be, subject to 
extensive and rigorous review and regulation by numerous government authorities in the U.S. and in other countries where we intend 
to test and market our product candidates. Before obtaining regulatory approvals for the commercial sale of any of our product 
candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product 
candidates are both safe and effective for use in each target indication. Because our product candidates are subject to regulation as 
biological drug products, we will need to demonstrate that they are safe, pure, and potent for use in their target indications. Each 
product candidate must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use. 
The risk/benefit profile required for product licensure will vary depending on these factors and may include not only the ability to 
show tumor shrinkage, but also adequate duration of response, a delay in the progression of the disease, and/or an improvement in 
survival. For example, response rates from the use of our product candidates may not be sufficient to obtain regulatory approval unless 
we can also show an adequate duration of response. Regulatory authorities may ultimately disagree with our chosen endpoints or may 
find that our studies or study results do not support product approval. Clinical testing is expensive and can take many years to 
complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of 
preclinical studies and early clinical trials of our product candidates with small patient populations may not be predictive of the results 
of later-stage clinical trials or the results once the applicable clinical trials are completed. Preliminary, single cohort, or top-line results 
from clinical studies may not be representative of the final study results. The results of studies in one set of patients or line of 
treatment may not be predictive of those obtained in another and the results in various human clinical trials reported in scientific and 
medical literature may not be indicative of results we obtain in our clinical trials. 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 initial clinical trials. 
Preclinical studies may also reveal unfavorable product candidate characteristics, including safety concerns. 

47 

We expect there may be greater variability in results for products processed and administered on a patient-by-patient basis, as 
anticipated for our product candidates, than for “off-the-shelf” products, like many other drugs. There is typically an extremely high 
rate of attrition from the failure of product candidates proceeding through clinical trials. Product candidates in later stages of clinical 
trials may fail to show the desired safety and efficacy profile despite having progressed through preclinical studies and initial clinical 
trials. Many companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of 
efficacy or unacceptable safety issues, notwithstanding promising results in earlier trials. Most product candidates that begin clinical 
trials are never approved by regulatory authorities for commercialization. 

In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same 

product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type 
of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial 
participants. Our current and future clinical trial results may not be successful. Moreover, should there be a flaw in a clinical trial, it 
may not become apparent until the clinical trial is well advanced. Further, because we currently plan to test our product candidates for 
use with other oncology products, the design, implementation, and interpretation of the clinical trials necessary for marketing approval 
may be more complex than if we were developing our product candidates alone. 

In addition, even if such trials are successfully completed, we cannot guarantee that the FDA or foreign regulatory authorities 

will interpret the results as we do, and more trials could be required before we submit our product candidates for approval. To the 
extent that the results of the trials are not satisfactory to the FDA or foreign regulatory authorities for support of a marketing 
application, we may be required to expend significant resources, which may not be available to us, to conduct additional trials in 
support of potential approval of our product candidates. 

We have reported preliminary results for clinical trials of our product candidates, including TIL for the treatment of metastatic 

melanoma, cervical cancer, and head and neck cancers. These preliminary results, which include assessments of efficacy such as 
ORR, are subject to substantial risk of change due to small sample sizes and may change as patients are evaluated or as additional 
patients are enrolled in these clinical trials. These outcomes may be unfavorable, deviate from our earlier reports, and/or delay or 
prevent regulatory approval or commercialization of our product candidates, including candidates for which we have reported 
preliminary efficacy results. In clinical studies where a staged expansion is expected, such as studies using a Simon’s two stage 
design, these outcomes may result in the failure to meet an initial efficacy threshold for the first stage. Furthermore, other measures of 
efficacy for these clinical trials and product candidates may not be as favorable. 

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or 

otherwise adversely affected. 

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll 

a sufficient number of patients, or similar patients in the pivotal program to the Phase 2, who remain in the trial until its conclusion. 
We may experience difficulties or delays in patient enrollment in our clinical trials for a variety of reasons, including: 

• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 

• 

the size and nature of the patient population; 
the severity of the disease under investigation; 
the patient eligibility criteria defined in the protocol; 
the size of the study population required for analysis of the trial’s primary endpoints; 
the proximity of patients to trial sites; 
the design of the trial; 
our ability to recruit clinical trial investigators with the appropriate competencies and experience; 
the efforts to facilitate timely enrollment in clinical trials and the effectiveness of recruiting publicity; 
the patient referral practices of physicians; 
competing clinical trials for similar therapies or other new therapeutics not involving cell-based immunotherapy; 
clinicians’ and patients’ perceptions as to the potential advantages and side effects of the product candidate being studied in 
relation to other available therapies, including any new drugs or treatments that may be approved for the indications we are 
investigating; 
clinical investigators enrolling patients who do not meet the enrollment criteria, requiring the inclusion of additional 
patients in the clinical trial; 

48 

• 

• 
• 
• 

the ongoing COVID-19 pandemic limiting our access to patients who would otherwise be eligible for enrollment, including 
treatment-naïve patients who may be more likely to seek standard of care therapies available at local treatment centers 
rather than enroll in a clinical trial at a larger hospital; 
approval of new indications for existing therapies or approval of new therapies in general; 
our ability to obtain and maintain patient consents; and 
the risk that patients enrolled in clinical trials will not complete a clinical trial, return for post-treatment follow-up, or 
follow the required study procedures. For instance, patients, including patients in any control groups, may withdraw from 
the clinical trial if they are not experiencing improvement in their underlying disease or condition. Withdrawal of patients 
from our clinical trials may compromise the quality of our data. 

In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas 

as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients 
who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Because the 
number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that 
some of our competitor’s use, which will reduce the number of patients who are available for our clinical trials at such clinical trial 
sites. Moreover, because our product candidates represent a departure from more commonly used methods for cancer treatment, 
potential patients and their doctors may be inclined to use conventional therapies, such as chemotherapy and approved 
immunotherapies, rather than enroll patients in any future clinical trial. In addition, potential enrollees may opt to participate in other 
clinical trials because of the length of time between the time that their tumor is excised and the TIL is infused back into the patient. 
Amendments to our clinical protocols may affect enrollment in, or results of, our trials, including amendments we have made to 
further define the patient population to be studied. 

Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment or small 
population size may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent 
completion of these trials and adversely affect our ability to advance the development of our product candidates. 

Our product candidates may cause undesirable side effects or have other properties that could halt their clinical 
development, prevent their regulatory approval, limit their commercial potential or result in significant negative consequences. 

Results of our trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. 
Undesirable side effects caused by our product candidates could cause us, IRBs, DSMBs, or regulatory authorities to interrupt, delay 
or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other 
comparable foreign regulatory authorities. Even if we were to receive product approval, such approval could be contingent on 
inclusion of unfavorable information in our product labeling, such as limitations on the indications for use for which the products may 
be marketed or distributed, a label with significant safety warnings, including boxed warnings, contraindications, and precautions, a 
label without statements necessary or desirable for successful commercialization, or requirements for costly post marketing testing and 
surveillance, or other requirements, including a Risk Evaluation and Mitigations Strategy or REMS, to monitor the safety or efficacy 
of the products, and in turn prevent us from commercializing and generating revenues from the sale of our current or future product 
candidates. 

If unacceptable toxicities or side effects arise in the development of our product candidates, we, an IRB, DSMB or the FDA or 
comparable foreign regulatory authorities could order us to cease clinical trials, order our clinical trials to be placed on clinical hold, 
or deny approval of our product candidates for any or all targeted indications. The FDA or comparable foreign regulatory authorities 
may also require additional data, clinical, or pre-clinical studies should unacceptable toxicities arise. We may need to abandon 
development or limit development of that product candidate to certain uses or subpopulations in which the undesirable side effects or 
other characteristics are less prevalent, less severe or more acceptable from a risk/benefit perspective. Toxicities associated with our 
trials and products may also negatively impact our ability to conduct clinical trials using TIL therapy in larger patient populations, 
such as in patients that have not yet been treated with other therapies or have not yet progressed on other therapies. 

Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete our trials or 
result in potential product liability claims. Such toxicities, which may arise from TIL therapy in general, including co-therapies, may 
include, for example, thrombocytopenia, chills, anemia, pyrexia, febrile neutropenia, diarrhea, neutropenia, vomiting, hypotension, 
and dyspnea. For example, the update in October 2018 from the C-144-01 trial included two grade 5 treatment emergent adverse 
events. In addition, these side effects and deaths may not be appropriately recognized or managed by the treating medical staff, as 
toxicities resulting from personalized cell therapy are not normally encountered in the general patient population and by medical 
personnel. Any of these occurrences may harm our business, financial condition and prospects significantly. 

49 

The manufacture of our product candidates is complex, and we may encounter difficulties in production, particularly with 
respect to process development, quality control, or scaling-up of our manufacturing capabilities. If we, or any of our third-party 
manufacturers encounter such difficulties, our ability to provide supply of our product candidates for clinical trials or our products 
for patients, if approved, could be delayed or stopped, or we may be unable to maintain a commercially viable cost structure. 

Our product candidates are biologics and the process of manufacturing our products is complex, highly regulated and subject to 

multiple risks. The manufacture of our product candidates involves complex processes, including harvesting tumor fragments from 
patients, isolating the T cells from the tumor fragments, multiplying the T cells to obtain the desired dose, and ultimately infusing the 
T cells back into a patient. As a result of the complexities, the cost to manufacture biologics is generally higher than traditional small 
molecule chemical compounds, and the manufacturing process is less reliable and is more difficult to reproduce. Our manufacturing 
process will be susceptible to product loss or failure due to logistical issues associated with the collection of tumor fragments, or 
starting material, from the patient, shipping such material to the manufacturing site, shipping the final product back to the patient, and 
infusing the patient with the product, manufacturing issues associated with the differences in patient starting material, interruptions in 
the manufacturing process, contamination, equipment failure, assay failures, improper installation or operation of equipment, vendor 
or operator error, inconsistency in cell growth, meeting pre-specified release criteria, and variability in product characteristics. Even 
minor deviations from normal manufacturing processes could result in reduced production yields, product defects, and other supply 
disruptions. If for any reason we lose a patient’s starting material, or later-developed product at any point in the process, or if any 
product does not meet the applicable specifications, the manufacturing process for that patient will need to be restarted, including 
resection of the proper amount of tumor fragment and the resulting delay may adversely affect that patient’s outcome. If microbial, 
viral, environmental or other contaminations are discovered in our product candidates or in the manufacturing facilities in which our 
product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and 
remedy the contamination. 

Because our product candidates are manufactured specifically for each individual patient, we will be required to maintain a 

chain of identity with respect to the patient’s tumor as it moves from the patient to the manufacturing facility, through the 
manufacturing process, and back to the patient. Maintaining such a chain of identity is difficult and complex, and failure to do so 
could result in adverse patient outcomes, loss of product, or regulatory action including withdrawal of our products from the market. 
Further, as product candidates are developed through preclinical to late-stage clinical trials towards approval and commercialization, it 
is common that various aspects of the development program, such as manufacturing methods, are altered along the way to optimize 
processes and results. Such changes carry the risk that they will not achieve these intended objectives, and any of these changes could 
cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials or 
otherwise necessitate the conduct of additional studies. 

Currently, our product candidates are manufactured using processes developed or modified by us or by our third-party research 
institution collaborators that we may not intend to use for more advanced clinical trials or commercialization. We have selected Gen 2 
as the manufacturing process for product registration, and all ongoing and future company-sponsored clinical trials. Although we 
believe Gen 2 is a commercially viable process, there are risks associated with scaling to the level required for advanced clinical trials 
or commercialization, including, among others, cost overruns, potential problems with process scale-up, process reproducibility, 
stability issues, lot consistency, and timely availability of raw materials. This includes potential risks associated with the FDA not 
agreeing with all of the details of our validation data or other aspects of our potency assay or assays for Cohort 4 of our C-144-01 
clinical trial. For example, on October 5, 2020, we announced that we and the FDA have not been able to agree on the required 
potency assays to fully define our TIL therapy, which is required as part of a BLA submission, and that as a result of these 
developments, our BLA submission was not expected by the end of 2020 and was anticipated instead to occur in 2021. Previously, we 
reported the submission of assay data to the FDA, and on May 18, 2021, we announced that we had received regulatory feedback from 
the FDA regarding our potency assays for lifileucel. Following FDA feedback regarding the potency assays for lifileucel, we have 
continued ongoing work developing and validating our potency assays and have engaged in discussions with the FDA during the 
second half of 2021. Our BLA submission for lifileucel is now expected to occur during the first half of 2022. As a result of these 
challenges, we may experience delays in our clinical development and/or commercialization plans. Furthermore, we may ultimately be 
unable to reduce the cost of goods for our product candidates to levels that will allow for an attractive return on investment if and 
when those product candidates are commercialized. 

Our current manufacturing strategy involves the use of CMOs. Currently our product candidates are manufactured by WuXi, 

Lonza, and Moffitt. Should we continue to use CMOs, we may not succeed in maintaining our relationships with our current CMOs or 
establishing relationships with additional or alternative CMOs. Our product candidates may compete with other products and product 
candidates for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations 
and that are both capable of manufacturing for us and willing to do so. If our CMOs should cease manufacturing for us, we would 

50 

experience delays in obtaining sufficient quantities of our product candidates for clinical trials and, if approved, commercial supply. 
Further, our CMOs may breach, terminate, or not renew these agreements. If we were to need to find alternative manufacturing 
facilities it would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if 
approved. The commercial terms of any new arrangement could be less favorable than our existing arrangements and the expenses 
relating to the transfer of necessary technology and processes could be significant. 

Reliance on third-party manufacturers entails exposure to risks to which we would not be subject if we manufactured the 

product candidate ourselves, including: 

• 
• 

• 
• 

• 

inability to negotiate manufacturing and quality agreements with third parties under commercially reasonable terms; 
reduced day-to-day control over the manufacturing process for our product candidates as a result of using third-party 
manufacturers for all aspects of manufacturing activities; 
reduced control over the protection of our trade secrets and know-how from misappropriation or inadvertent disclosure; 
termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that may be costly or 
damaging to us or result in delays in the development or commercialization of our product candidates; and 
disruptions to the operations of our third-party manufacturers or suppliers caused by conditions unrelated to our business or 
operations, including the bankruptcy of the manufacturer or supplier. 

In May 2019 we entered into a lease agreement to build a commercial-scale manufacturing facility in Philadelphia, 
Pennsylvania for commercial and clinical production of autologous TIL products, including our product candidate lifileucel. We 
expect that development of our own manufacturing facility will provide us with enhanced control of material supply for both clinical 
trials and the commercial market, enable the more rapid implementation of process changes, and allow for better long-term margins. 
However, we have no experience as a company in developing a manufacturing facility and we may not be successful in finalizing the 
development of our own manufacturing facility or capability. We may establish multiple manufacturing facilities as we expand our 
commercial footprint to multiple geographies, which may lead to regulatory delays or prove costly. Even if we are successful, our 
manufacturing capabilities could be affected by cost-overruns, unexpected delays, equipment failures, labor shortages, natural 
disasters, power failures, and numerous other factors that could prevent us from realizing the intended benefits of our manufacturing 
strategy and have a material adverse effect on our business. 

The manufacture of cell therapy products requires significant expertise and capital investment, including the development of 

advanced manufacturing techniques and process controls. Manufacturers of cell therapy products often encounter difficulties in 
production, particularly in scaling up initial production. These problems include difficulties with production costs and yields, quality 
control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel, and compliance 
with strictly enforced federal, state, local and foreign regulations. 

Moreover, any problems or delays we or our CMOs experience in preparing for commercial scale manufacturing of a product 
candidate or component may result in a delay in the FDA approval of the product candidate or may impair our ability to manufacture 
commercial quantities or such quantities at an acceptable cost, which could result in the delay, prevention, or impairment of clinical 
development and commercialization of our product candidates and could adversely affect our business. Furthermore, if we or our 
commercial manufacturers fail to deliver the required commercial quantities of our product candidates on a timely basis and at 
reasonable costs, we would likely be unable to meet demand for our products and we would lose potential revenues. 

In addition, the manufacturing process and facilities for any products that we may develop is subject to FDA and foreign 
regulatory authority approval processes, and we or our CMOs will need to meet all applicable FDA and foreign regulatory authority 
requirements, including cGMPs, on an ongoing basis. The cGMP requirements include quality control, quality assurance, and the 
maintenance of records and documentation. The FDA and other regulatory authorities enforce these requirements through facility 
inspections. Manufacturing facilities must submit to pre-approval inspections by the FDA that will be conducted after we submit our 
marketing applications, including our BLAs, to the FDA. Manufacturers are also subject to continuing regulatory oversight by FDA 
and other regulatory authorities, including inspections following marketing approval. Further, we, in cooperation with our CMOs, 
must supply all necessary chemistry, manufacturing, and control documentation for a pre-approval inspection in support of a BLA on 
a timely basis.  There is no guarantee that we or our CMOs will be able to successfully pass all aspects of a pre-approval inspection by 
the FDA or other foreign regulatory authorities. 

Our, or our CMOs’ manufacturing facilities may be unable to comply with our specifications, cGMPs, and with other FDA, 

state, and foreign regulatory requirements. Poor control of production processes can lead to the introduction of adventitious agents or 
other contaminants, or to inadvertent changes in the properties or stability of product candidate that may not be detectable in final 

51 

product testing. If we or our CMOs are unable to reliably produce products to specifications acceptable to the FDA or other regulatory 
authorities, or in accordance with the strict regulatory requirements, we may not obtain or maintain the approvals we need to 
commercialize such products. Even if we obtain regulatory approval for any of our product candidates, there is no assurance that either 
we or our CMOs will be able to manufacture the approved product to specifications acceptable to the FDA or other regulatory 
authorities, to produce it in sufficient quantities to meet the requirements for the potential launch of the product, or to meet potential 
future demand. Deviations from manufacturing requirements may further require remedial measures that may be costly and/or time-
consuming for us or a third party to implement and may include the temporary or permanent suspension of a clinical trial or 
commercial sales or the temporary or permanent closure of a facility. Any such remedial measures imposed upon us or third parties 
with whom we contract could materially harm our business. 

Even to the extent we use and continue to use CMOs, we are ultimately responsible for the manufacture of our products and 

product candidates. A failure to comply with these requirements may result in regulatory enforcement actions against our 
manufacturers or us, including fines and civil and criminal penalties, which could result in imprisonment, suspension or restrictions of 
production, injunctions, delay or denial of product approval or supplements to approved products, clinical holds or termination of 
clinical studies, warning or untitled letters, regulatory authority communications warning the public about safety issues with the 
biologic, refusal to permit the import or export of the products, product seizure, detention, or recall, operating restrictions, suits under 
the civil False Claims Act, corporate integrity agreements, consent decrees, or withdrawal of product approval. 

Any of these challenges could delay completion of clinical trials, require bridging clinical trials or the repetition of one or more 
clinical trials, increase clinical trial costs, delay approval of our product candidate, impair commercialization efforts, increase our cost 
of goods, and have an adverse effect on our business, financial condition, results of operations and growth prospects. 

Cell-based therapies and biologics rely on the availability of reagents, specialized equipment, and other specialty materials, 

which may not be available to us on acceptable terms or at all. For some of these reagents, equipment, and materials, we rely or 
may rely on sole source vendors or a limited number of vendors, which could impair our ability to manufacture and supply our 
products. 

Manufacturing our product candidates requires many reagents, which are substances used in our manufacturing processes to 

bring about chemical or biological reactions, and other specialty materials and equipment, some of which are manufactured or 
supplied by small companies with limited resources and experience to support commercial biologics production. We currently depend 
on a limited number of vendors for certain materials and equipment used in the manufacture of our product candidates. Some of these 
suppliers may not have the capacity to support clinical trials and commercial products manufactured under cGMP by 
biopharmaceutical firms or may otherwise be ill-equipped to support our needs. We also do not have supply contracts with many of 
these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Accordingly, we may 
experience delays in receiving key materials and equipment to support clinical or commercial manufacturing. 

For some of these reagents, equipment, and materials, we rely and may in the future rely on sole source vendors or a limited 

number of vendors. An inability to continue to source product from any of these suppliers, which could be due to a number of issues, 
including regulatory actions or requirements affecting the supplier, adverse financial or other strategic developments experienced by a 
supplier, labor disputes or shortages, unexpected demands, or quality issues, could adversely affect our ability to satisfy demand for 
our product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct 
clinical trials, either of which could significantly harm our business. 

As we continue to develop and scale our manufacturing process, we expect that we will need to obtain rights to and supplies of 

certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on 
commercially reasonable terms, or at all, and if we are unable to alter our process in a commercially viable manner to avoid the use of 
such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our 
process so as to use other materials or equipment, such a change may lead to a delay in our clinical development and/or 
commercialization plans. If such a change occurs for product candidate that is already in clinical testing, the change may require us to 
perform both ex vivo comparability studies and to collect additional data from patients prior to undertaking more advanced clinical 
trials. 

We will be unable to commercialize our products if our trials are not successful. 

With the exception of lifileucel for metastatic melanoma and metastatic cervical cancer, our research and development 
programs are at an early stage. We must demonstrate our products’ safety and efficacy in humans through extensive clinical testing. 

52 

We may experience numerous unforeseen events during, or as a result of, the testing process that could delay or prevent 
commercialization of our products, including but not limited to the following: 

• 

• 

safety and efficacy results in various human clinical trials reported in scientific and medical literature may not be indicative 
of results we obtain in our clinical trials; 
after reviewing test results, we or our collaborators may abandon projects that we might previously have believed to be 
promising; 

•  we, our collaborators or regulators, may suspend or terminate clinical trials if the participating subjects or patients are 

• 

being exposed to unacceptable health risks; 
the effects our potential products have may not be the desired effects or may include undesirable side effects or other 
characteristics that preclude regulatory approval or limit their commercial use if approved; 

•  manufacturers may not meet the necessary standards for the production of the product candidates or may not be able to 

supply the product candidates in a sufficient quantity; and 
regulatory authorities may find that our clinical trial design or conduct does not meet the applicable approval requirements. 

• 

Clinical testing is very expensive, can take many years, and the outcome is uncertain. It could take as much as 12 months or 

more before we learn the results from any clinical trial using our adoptive cell therapy with TIL. The data collected from our clinical 
trials may not be sufficient to support approval by the FDA of our TIL-based product candidates for the treatment of solid tumors. The 
clinical trials for our products under development may not be completed on schedule and the FDA may not ultimately approve any of 
our product candidates for commercial sale. If we fail to adequately demonstrate the safety and efficacy of any product candidate 
under development, we may not receive regulatory approval for those products, which would prevent us from generating revenues or 
achieving profitability. 

Even if our lead product lifileucel is approved and commercialized, we may not become profitable. 

Our lead product, lifileucel, is initially targeting a small population of refractory patients that suffer from metastatic melanoma 
and metastatic cervical cancer. Even if the FDA approves these new therapies, and even if we obtain significant market share for each  
product candidate, because the potential target population for lifileucel in refractory patients may be small, we may never achieve 
profitability without obtaining regulatory approval for additional indications. The FDA often approves new therapies initially only for 
use in patients with relapsed or refractory metastatic disease. We expect to initially seek approval of our product candidates in this 
setting and are currently studying these patient populations. 

We collaborate with governmental, academic and corporate partners to improve and develop TIL therapies for new 
indications for use in combination with other therapies and to evaluate new TIL manufacturing methods, the results of which, 
because the manufacturing processes are not within our control, may be incorrect or unreliable. 

In addition to our own research and process development efforts, we seek to collaborate with government, academic research 

institutions and corporate partners to improve TIL manufacturing and to develop TIL therapies for new indications. In 2017-2020, we 
announced our continued collaborations with Moffitt, MDACC, and The Ohio State University to evaluate several new solid tumor 
and hematologic indications for TIL therapy in clinical and preclinical studies as well as, in some cases, new TIL manufacturing 
approaches. The results of these collaborations may be used to support our filing with the FDA of INDs to conduct more advanced 
clinical trials of our product candidates, or to otherwise analyze or make predictions or decisions with respect to our current or future 
product candidates. However, because the majority of our collaborations are conducted at outside laboratories and we do not have 
complete control over how the studies are conducted or reported or over the manufacturing methods used to manufacture TIL product, 
the results of such studies, which we may use as the basis for our conclusions, projections or decisions with respect to our current or 
future product candidates, may be incorrect or unreliable, or may have a negative impact on us if the results of such studies are 
imputed to our products or proposed indications, even if such imputation is improper. For example, we have entered into 
collaborations with Moffitt, and MDACC to perform clinical trials using TIL products that differ from our products, but the results of 
these clinical trials, if negative, may adversely impact our stock price and our development plans for our products. Additionally, we 
may use third party data to analyze, reach conclusions or make predictions or decisions with respect to our product candidates that 
may be incomplete, inaccurate or otherwise unreliable. 

53 

We may need additional financing to fund our operations and complete the development and commercialization of our 
various product candidates, and if we are unable to obtain such financing, we may be unable to complete the development and 
commercialization of our product candidates. Raising additional capital may cause dilution to our existing stockholders, restrict 
our operations or require us to relinquish rights to our technologies or product candidates. 

Our operations have consumed substantial amounts of cash since inception. From our inception to December 31, 2021, we have 

an accumulated deficit of $1.2 billion. In addition, our research and development and our operating costs have also been substantial 
and are expected to increase. For example, in October 2018, we closed an underwritten public offering of our common stock. The net 
proceeds from the offering, after deducting the underwriting discounts and commissions and other offering expenses payable by us, 
were $236.7 million. In June 2020, we closed another underwritten offering of our common stock. The net proceeds from the offering, 
after deducting the underwriting discounts and commissions and other offering expenses payable by us, were $567.0 million. In 
February 2021 we entered into an open market sale agreement, or the Sales Agreement, with Jefferies LLC, which provides for the 
sale of up to $350.0 million of our common stock from time to time.  For the year ended December 31, 2021, we received $203.2 
million in net proceeds through the sale of 6,474,099 shares of our common stock. As of December 31, 2021, we had $602.1 million 
in cash, cash equivalents and investments ($78.2 million of cash and cash equivalents, $426.2 million in short-term investments, $91.6 
million of long-term investments, and restricted cash of $6.1 million). 

Accordingly, we believe that our existing cash, cash equivalents and investments will be sufficient to fund our operations for at 

least the next twelve months from the date this Annual Report on Form 10-K is issued. However, in order to complete the 
development of our current product candidates, and in order to affect our business plan, including establishing our own manufacturing 
facility, we anticipate that we will have to spend more than the funds currently available to us. Furthermore, changing circumstances 
may cause us to increase our spending significantly faster than we currently anticipate, and we may require additional capital for the 
further development and commercialization of our product candidates and may need to raise additional funds sooner if we choose to 
expand more rapidly than we presently anticipate. Moreover, our fixed expenses such as rent, minimum payments to our contract 
manufacturers, and other contractual commitments, including those for our research collaborations, are substantial and are expected to 
increase in the future. 

We will need to obtain additional financing to fund our future operations, including completing the development and 

commercialization of our product candidates. Our future funding requirements will depend on many factors, including, but not limited 
to: 

• 

• 

• 
• 

• 

• 

• 
• 

• 
• 
• 
• 
• 

progress, timing, scope and costs of our clinical trials, including the ability to timely initiate clinical sites, enroll subjects 
and manufacture TIL for treatment for patients in our ongoing, planned and potential future clinical trials; 
time and cost necessary to obtain regulatory approvals that may be required by regulatory authorities to execute clinical 
trials or commercialize our product; 
our ability to successfully commercialize our product candidates, if approved; 
our ability to have clinical and commercial product successfully manufactured consistent with FDA and European 
Medicines Agency, or EMA, regulations; 
amount of sales and other revenues from product candidates that we may commercialize, if any, including the selling prices 
for such potential products and the availability of adequate third-party coverage and reimbursement for patients; 
sales and marketing costs associated with commercializing our products, if approved, including the cost and timing of 
building our marketing and sales capabilities; 
cost of building, staffing and validating our own manufacturing facility in the U.S.; 
terms and timing of our current and any potential future collaborations, licensing or other arrangements that we have 
established or may establish; 
cash requirements of any future acquisitions or the development of other product candidates; 
costs of operating as a public company; 
time and cost necessary to respond to technological, regulatory, political and market developments; 
costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; and 
costs associated with any potential business or product acquisitions, strategic collaborations, licensing agreements or other 
arrangements that we may establish. 

Unless and until we can generate a sufficient amount of revenue, we may finance future cash needs through public or private 
equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing or distribution arrangements. 
Additional funds may not be available when we need them on terms that are acceptable to us, or at all. We have no committed source 

54 

of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may be 
required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization 
efforts. Our current license and collaboration agreements may also be terminated if we are unable to meet the payment obligations 
under those agreements. As a result, we may seek to access the public or private capital markets whenever conditions are favorable, 
even if we do not have an immediate need for additional capital at that time. 

To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest 

will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The 
incurrence of indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, such as 
limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other 
operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic 
partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies 
or product candidates, or grant licenses on terms unfavorable to us. 

Subject to various spending levels approved by our Board of Directors, our management will have broad discretion in the 

use of the net proceeds from our capital raises, including our June 2020, October 2018 and January 2018 public offerings and the 
proceeds from sales pursuant to our “at-the-market” sales agreement with Jefferies LLC, and may not use them effectively. 

Our management will have discretion in the application of the net proceeds from our capital raises, including our June 2020, 
October 2018, and January 2018 public offerings, and the proceeds from sales pursuant to the Sales Agreement with Jefferies LLC, 
which provides for the sale of up to $350.0 million of our common stock from time to time, and our stockholders will not have the 
opportunity as part of their investment decision to assess whether the net proceeds from our capital raises are being used appropriately. 
You may not agree with our decisions, and our use of the proceeds from our capital raises may not yield any return to stockholders. 
Because of the number and variability of factors that will determine our use of the net proceeds from our capital raises, their ultimate 
use may vary substantially from their currently intended use. Our failure to apply the net proceeds of our capital raises effectively 
could compromise our ability to pursue our growth strategy and we might not be able to yield a significant return, if any, on our 
investment of those net proceeds. Stockholders will not have the opportunity to influence our decisions on how to use our net proceeds 
from our capital raises. Pending their use, we may invest the net proceeds from our capital raises in interest and non-interest bearing 
cash accounts, short-term, investment-grade, interest-bearing instruments and U.S. government securities. These temporary 
investments are not likely to yield a significant return. 

The use of our net operating loss carryforwards and research tax credits may be limited. 

Our net operating loss carryforwards and any future research and development tax credits may expire and not be used. As of 
December 31, 2021, we had U.S. federal net operating loss carryforwards of approximately $945.3 million. Our net operating loss 
carryforwards arising in taxable years ending on or prior to December 31, 2017 will begin expiring in 2027 if we have not used them 
prior to that time. Net operating loss carryforwards arising in taxable years ending after December 31, 2017 are no longer subject to 
expiration under the Internal Revenue Code of 1986, as amended, or the Code. Additionally, our ability to use any net operating loss 
and credit carryforwards to offset taxable income or tax, respectively, in the future will be limited under Sections 382 and 383 of the 
Code, respectively, if we have a cumulative change in ownership of more than 50% within a three-year period. 

Prior to December 31, 2020, we have experienced multiple ownership changes. As a result, the federal and state carryforwards 

associated with the net operating loss and credit deferred tax assets were reduced by the amount of tax attributes estimated to expire 
during their respective carryforward periods. In addition, since we will need to raise substantial additional funding to finance our 
operations, we may undergo further ownership changes in the future. Any such annual limitation may significantly reduce the 
utilization of the net operating loss carryforwards and research tax credits before they expire. Depending on our future tax position, 
limitation of our ability to use net operating loss carryforwards in states in which we are subject to income tax could have an adverse 
impact on our results of operations and financial condition. 

Recently enacted tax reform legislation in the U.S., changes to existing tax laws, or challenges to our tax positions could 

adversely affect our business and financial condition. 

In recent years, various tax legislations were signed into law. On December 22, 2017, the Tax Cuts and Jobs Act of 2017, or the 

Tax Act, was signed into law, making significant changes to the Internal Revenue Code.  

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, was enacted in response to 
the COVID-19 pandemic. Certain provisions of the CARES Act amend or suspend certain provisions of the Tax Act.  For example, 

55 

the tax relief measures under the CARES Act for businesses include a five-year net operating loss carryback, suspension of annual 
deduction limitation of 80% of taxable income from net operating losses generated in a tax year beginning after December 31, 2017, 
changes in the deductibility of interest, acceleration of alternative minimum tax credit refunds, payroll tax relief, and a technical 
correction to allow accelerated deductions for qualified improvement property.  On June 15, 2020, Assembly Bill 85 was passed in 
California which suspended the use of net operating losses and limited the use of credits for certain corporations. Changes to existing 
federal and state tax laws could adversely impact our business, results of operations and financial position as the impact of recent tax 
legislation is uncertain.   

In addition, U.S. federal, state and local tax laws are extremely complex and subject to various interpretations. Although we 

believe that our tax estimates and positions are reasonable, including our decision to build our iCTC facility at the Navy Yard in 
Philadelphia in order to take advantage of the site's designation as a Keystone Opportunity Zone, Keystone Opportunity Expansion 
Zone, or Keystone Opportunity Improvement Zone, or collectively KOZ, which allows incentives for business development, as well 
as certain other financial incentives provided by the Commonwealth of Pennsylvania, the City of Philadelphia and the Philadelphia 
Industrial Development Corporation, there can be no assurance that our tax positions will not be challenged by relevant tax authorities 
or that we would be successful in any such challenge. Further, challenges to the site's designation as a KOZ or broader challenges to 
Pennsylvania's KOZ program could result in the revocation of the site's designation as a KOZ and the attendant tax advantages 
associated with such designation. If we are unsuccessful in such a challenge, or if the site's status as a KOZ is revoked, the relevant tax 
authorities may assess additional taxes, which could result in adjustments to, or impact the timing or amount of, taxable income, 
deductions or other tax allocations, which may adversely affect our results of operations and financial position. 

We are subject to extensive regulation, which can be costly, time consuming and can subject us to unanticipated delays; 

even if we obtain regulatory approval for some of our products, those products may still face regulatory difficulties. 

Our potential products, cell processing and manufacturing activities, are subject to comprehensive regulation by the FDA in the 

U.S. and by comparable authorities in other countries. The process of obtaining FDA and other required regulatory approvals, 
including foreign approvals, is expensive and often takes many years and can vary substantially based upon the type, complexity and 
novelty of the products involved. In addition, regulatory agencies may lack experience with our technologies and products, which may 
lengthen the regulatory review process, increase our development costs and delay or prevent their commercialization. 

No adoptive cell therapy using TIL has been approved for marketing by the FDA. Consequently, there is no precedent for the 
successful commercialization of products based on our technologies. In addition, we have had only limited experience in filing and 
pursuing applications necessary to gain regulatory approvals, which may impede our ability to obtain timely FDA approvals, if at all. 
We have not yet sought FDA approval for any adoptive cell therapy product. We will not be able to commercialize any of our 
potential products until we obtain FDA approval, and so any delay in obtaining, or inability to obtain, FDA approval would harm our 
business. 

If we violate regulatory requirements at any stage, whether before or after marketing approval is obtained, we may face a 
number of regulatory consequences, including refusal to approve pending applications, license suspension or revocation, withdrawal 
of an approval, imposition of a clinical hold or termination of clinical trials, warning letters, untitled letters, modification of 
promotional materials or labeling, provision of corrective information, imposition of post-market requirements including the need for 
additional testing, imposition of distribution or other restrictions under a REMS, product recalls, product seizures or detentions, 
refusal to allow imports or exports, total or partial suspension of production or distribution, FDA debarment, injunctions, fines, 
consent decrees, corporate integrity agreements, debarment from receiving government contracts, and new orders under existing 
contracts, exclusion from participation in federal and state healthcare programs, restitution, disgorgement, or civil or criminal 
penalties, including fines and imprisonment, and adverse publicity, among other adverse consequences. Additionally, we may not be 
able to obtain the labeling claims necessary or desirable for the promotion of our products. We may also be required to undertake post-
marketing trials. In addition, if we or others identify side effects after any of our adoptive cell therapies are on the market, or if 
manufacturing problems occur, regulatory approval may be withdrawn, and reformulation of our products may be required. 

We may not be able to license new technology from third parties. 

An element of our intellectual property portfolio is to license additional rights and technologies from third parties, including the 
NIH and others. Our inability to license the rights and technologies that we have identified, or that we may in the future identify, could 
have a material adverse impact on our ability to complete the development of our products or to develop additional products. No 
assurance can be given that we will be successful in licensing any additional rights or technologies from third parties, including the 

56 

NIH and others. Failure to obtain additional rights and licenses may detrimentally affect our planned development of additional 
product candidates and could increase the cost, and extend the timelines associated with our development of such other products. 

Our projections regarding the market opportunities for our product candidates may not be accurate, and the actual market 

for our products may be smaller than we estimate. 

Our projections of both the number of people who have the cancers we are targeting, as well as the subset of people with these 
cancers who are in a position to receive second- or third- line therapy, and who have the potential to benefit from treatment with our 
product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including 
scientific literature, surveys of clinics, patient foundations, or market research by third parties, and may prove to be incorrect. Further, 
new studies or approvals of new therapeutics may change the estimated incidence or prevalence of these cancers. The number of 
patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for our product candidates 
may be limited or may not be amenable to treatment with our product candidates and may also be limited by the cost of our treatments 
and the reimbursement of those treatment costs by third-party payors. For instance, we expect lifileucel to initially target a small 
patient population that suffers from metastatic melanoma. Even if we obtain significant market share for our product candidates, 
because the potential target populations are small, we may never achieve profitability without obtaining regulatory approval for 
additional indications. 

We are required to pay substantial royalties and lump sum benchmark payments under our license agreements with the 

NIH, Moffitt, Novartis, and Cellectis, and we must meet certain milestones to maintain our license rights. 

Under our license agreements with the NIH, Novartis, and Cellectis for our adoptive cell therapy and immunotherapy 
technologies, we are currently required to pay both substantial benchmark payments and royalties to that institution based on our 
revenues from sales of our products utilizing the licensed technologies. These payments could adversely affect the overall profitability 
for us of any products that we may seek to commercialize under these license agreements. In order to maintain our license rights under 
the NIH, Moffitt, Novartis, and Cellectis license agreements, we will need to meet certain specified milestones, subject to certain cure 
provisions, in the development of our product candidates. There is no assurance that we will be successful in meeting these milestones 
on a timely basis, or at all. 

Because our current products represent, and our other potential product candidates will represent novel approaches to the 
treatment of disease, there are many uncertainties regarding the development, the market acceptance, third-party reimbursement 
coverage and the commercial potential of our product candidates. 

Human immunotherapy products are a new category of therapeutics. Because this is a relatively new and expanding area of 

novel therapeutic interventions, there are many uncertainties related to development, marketing, reimbursement, and the commercial 
potential for our product candidates. There can be no assurance as to the length of the trial period, the number of patients the FDA will 
require to be enrolled in the trials in order to establish the safety, efficacy, purity and potency of immunotherapy products, or that the 
data generated in these trials will be acceptable to the FDA to support marketing approval. The FDA may take longer than usual to 
come to a decision on any BLA that we submit and may ultimately determine that there is not enough data, information, or experience 
with our product candidates to support an approval decision. The FDA may also require that we conduct additional post-marketing 
studies or implement risk management programs, such as REMS until more experience with our product candidates is obtained. 
Finally, after increased usage, we may find that our product candidates do not have the intended effect or have unanticipated side 
effects, potentially jeopardizing initial or continuing regulatory approval and commercial prospects. 

We may also find that the manufacture of our product candidates is more difficult than anticipated, resulting in an inability to 

produce a sufficient amount of our product candidates for our clinical trials or, if approved, commercial supply. Moreover, because of 
the complexity and novelty of our manufacturing process, there are only a limited number of manufacturers who have the capability of 
producing our product candidates. Should any of our contract manufacturers no longer produce our product candidates, it may take us 
significant time to find a replacement, if we are able to find a replacement at all. 

There is no assurance that the approaches offered by our products will gain broad acceptance among doctors or patients or that 

governmental agencies or third-party medical insurers will be willing to provide reimbursement coverage for proposed product 
candidates. Moreover, we do not have verifiable internal marketing data regarding the potential size of the commercial market for our 
product candidates, nor have we obtained current independent marketing surveys to verify the potential size of the commercial 
markets for our current product candidates or any future product candidates. Since our current product candidates and any future 
product candidates will represent novel approaches to treating various conditions, it may be difficult, in any event, to accurately 

57 

estimate the potential revenues from these product candidates. Accordingly, we may spend significant capital trying to obtain approval 
for product candidates that have an uncertain commercial market. The market for any products that we successfully develop will also 
depend on the cost of the product. We do not yet have sufficient information to reliably estimate what it will cost to commercially 
manufacture our current product candidates, and the actual cost to manufacture these products could materially and adversely affect 
the commercial viability of these products. Our goal is to reduce the cost of manufacturing and providing our therapies. However, 
unless we can reduce those costs to an acceptable amount, we may never be able to develop a commercially viable product. If we do 
not successfully develop and commercialize products based upon our approach or find suitable and economical sources for materials 
used in the production of our products, we will not become profitable, which would materially and adversely affect the value of our 
common stock. 

Our TIL therapies and our other therapies may be provided to patients in combination with other agents provided by third 
parties. The cost of such combination therapy may increase the overall cost of therapy and may result in issues regarding the allocation 
of reimbursements between our therapy and the other agents, all of which may affect our ability to obtain reimbursement coverage for 
the combination therapy from governmental or private third party medical insurers. 

No assurance can be given that the Gen 2 manufacturing process we have selected will be FDA-compliant, more efficient 

and lower the cost to manufacture TIL products. 

Pursuant to the CRADA, and in cooperation with our contract manufacturers and potentially other manufacturers, we have 

developed and are developing improved methods for the generating and selecting autologous TILs, and methods for large-scale 
production of autologous TILs that are in accord with current cGMP procedures. We have developed a new and more efficient TIL 
manufacturing process that we believe can be more efficient and cost effective, and in a more automated manner than previous 
processes. The production and control of the physical and/or chemical attributes of our products in a cGMP facility is subject to many 
uncertainties and difficulties. We have never manufactured our adoptive cell therapy product candidate on a commercial scale, nor 
have our partners. As a result, we cannot give any assurance that the Gen 2 process or any future process that we select will be a 
manufacturing process that can produce our products in compliance with the applicable regulatory requirements, at a cost or in 
quantities necessary to make them commercially viable. Moreover, we and our third-party manufacturers will have to continually 
adhere to current cGMP regulations enforced by the FDA through its facilities inspection program. If our facilities or any of the 
facilities of these manufacturers cannot demonstrate adequate assurance of compliance with FDA standards during a pre-approval 
inspection, the FDA approval of our products will not be granted. In complying with cGMP and foreign regulatory requirements, we 
and any of our third-party manufacturers will be obligated to expend time, money and effort in production, record-keeping and quality 
control to assure that our products meet applicable specifications and other requirements. If we or any of our third-party manufacturers 
fail to comply with these requirements, we may be subject to regulatory action. No assurance can be given that we will be able to 
develop such a manufacturing process, or that our partners will thereafter be able to establish and operate such a production facility. 

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit 

commercialization of our product candidates. 

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even 

greater risk if we commercialize any products. For example, we may be sued if our product candidates cause or are perceived to cause 
injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability 
claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, 
negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. Large 
judgements have also been awarded in class action lawsuits based on therapeutics that had unanticipated side effects. If we cannot 
successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit 
commercialization of our product candidates. Even successful defense would require significant financial and management resources. 
Regardless of the merits or eventual outcome, liability claims may result in: 

decreased demand for our product candidates; 
injury to our reputation; 

• 
• 
•  withdrawal of clinical trial participants or sites and potential termination of clinical trial sites or entire clinical programs; 
• 
initiation of investigations by regulators, refusal to approve marketing applications or supplements, and withdrawal or 
limitation of product approvals; 
costs to defend the related litigation; 
a diversion of management’s time and our resources; 
substantial monetary awards to trial participants or patients; 

• 
• 
• 

58 

• 
• 
• 
• 
• 
• 

product recalls, withdrawals or labeling, marketing or promotional restrictions; 
loss of revenue; 
significant negative media attention; 
decrease in the price of our stock and overall value of our company; 
exhaustion of our available insurance coverage and our capital resources; or 
the inability to commercialize our product candidates. 

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability 
claims could prevent or inhibit the commercialization of products we develop, alone or with corporate collaborators. Our insurance 
policies may also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. While 
we have obtained clinical trial insurance for our Phase 2 clinical trials, we may have to pay amounts awarded by a court or negotiated 
in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to 
obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to 
indemnification against losses, such indemnification may not be available or adequate should any claim arise. 

We face significant competition from other biotechnology and pharmaceutical companies and from non-profit institutions. 

Competition in the field of cancer therapy is intense and is accentuated by the rapid pace of technological development. 
Research and discoveries by others may result in breakthroughs which may render our products obsolete even before they generate 
any revenue. There are products that are approved and currently under development by others that could compete with the products 
that we are developing. Many of our potential competitors have substantially greater research and development capabilities and 
approval, manufacturing, marketing, financial and managerial resources and experience than we do. Our competitors may: 

• 
• 
• 
• 

develop safer, more convenient or more effective immunotherapies and other therapeutic products; 
develop therapies that are less expensive or have better reimbursement from private or public payors; 
reach the market more rapidly, reducing the potential sales of our products; or 
establish superior proprietary positions. 

Due to the promising clinical therapeutic effect of competitor therapies in clinical exploratory trials, we anticipate substantial 
direct competition from other organizations developing advanced T cell therapies targeting patients who have received prior anti-PD-
1/PD-L1 therapies. In particular, we expect to compete with other new therapies for our lead indications developed by companies such 
as Agenus, BeyondSpring, Bristol-Myers Squibb, Merck, Nektar Therapeutics, Idera Pharmaceuticals, Checkmate Pharmaceuticals, 
Daiichi Sankyo, Eisai, Exelixis, Mirati Therapeutics, OncoSec Medical, Replimune, Regeneron Pharmaceuticals, Seagen, and 
Genmab. We also may compete with other TIL therapies in development by companies such as Instil Bio, Achilles Therapeutics, KSQ 
Therapeutics, Obsidian Therapeutics, Immatics, TILT Biotherapeutics, WindMIL Therapeutics, GRIT Biotechnology, Lyell 
Immunopharma, Cellular Biomedicine Group, and others. We also may compete with therapies based on genetically engineered T cell 
receptors rendered reactive against tumor-associated antigens prior to their administration to patients, as well as TIL therapies that are 
designed to be specific to neoantigens, including products developed by Adaptimmune Therapeutics, Alaunos Therapeutics, Marker 
Therapeutics, Turnstone Biologics, Neogene, and others. To date, these technologies have been primarily applicable to hematologic 
malignancies, but their application in solid tumor indications may create competition with us. We may also face competition from 
immunotherapy treatments offered by companies such as Amgen, AstraZeneca, Bristol-Myers Squibb, Merck, Pfizer, Regeneron 
Pharmaceuticals, and Roche. We may also face competition from novel interleukin-2 (IL-2) treatments in development by Werewolf, 
Nektar Therapeutics, Merck, Sanofi, Neoleukin Therapeutics and others. Many of these companies and our other current and potential 
competitors have substantially greater research and development capabilities and financial, scientific, regulatory, manufacturing, 
marketing, sales, human resources, and experience than we do. Many of our competitors have several therapeutic products that have 
already been developed, approved and successfully commercialized, or are in the process of obtaining regulatory approval for their 
therapeutic products in the U.S. and internationally. Our competitors may obtain regulatory approval for their products more rapidly 
than we may obtain approval for ours, which could result in competitors establishing a strong market position before we are able to 
enter the market. 

Universities and public and private research institutions in the U.S. and Europe are also potential competitors. For example, a 
Phase 3 trial comparing TIL to standard ipilimumab in patients with metastatic melanoma is currently being conducted in Europe by 
the Netherlands Cancer Institute, the Copenhagen County Herlev University Hospital, and the University of Manchester. While these 
universities and public and private research institutions primarily have educational objectives, they may develop proprietary 
technologies that lead to other FDA approved therapies or that secure patent protection that we may need for the development of our 
technologies and products.

Our lead product candidate lifileucel is a therapy for the treatment of metastatic melanoma and metastatic cervical cancer. 
Currently, there are numerous companies that are developing various alternate treatments for melanoma and cervical cancer, including 
patients that have progressed after prior treatment with checkpoint inhibitors and chemotherapy. Accordingly, lifileucel faces 
significant competition in the melanoma and cervical cancer treatment space from multiple companies. Even if we obtain regulatory 
approval for lifileucel, the availability and price of our competitors’ products could limit the demand and the price we are able to 
charge for our therapies. We may not be able to implement our business plan if the acceptance of our products is inhibited by price 
competition or the reluctance of physicians to switch from other methods of treatment to our product, or if physicians switch to other 
new therapies, drugs or biologic products or choose to reserve our product for use in limited circumstances. 

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being 

concentrated among a smaller number of our competitors. Early-stage companies may also prove to be significant competitors, 
particularly through collaborative arrangements with large and established companies. These third parties compete with us in 
recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for 
clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. 

We are dependent on third parties to support our research, development and manufacturing activities and, therefore, are 

subject to the efforts of these parties and our ability to successfully collaborate with these third parties. 

As a result of our current strategy to outsource most of our manufacturing, we rely very heavily on third parties to perform for 
us the manufacturing of our products for our clinical trials. We also license a portion of our technology from others. We intend to rely 
upon our contract manufacturers to produce large quantities of materials needed for clinical trials and potentially product 
commercialization. Third party manufacturers may not be able to meet our needs with respect to timing, quantity or quality. If we are 
unable to contract for a sufficient supply of needed materials on acceptable terms, or if we should encounter delays or difficulties in 
our relationships with manufacturers, our clinical testing may be delayed, thereby delaying the submission of products for regulatory 
approval or the market introduction and subsequent sales of our products. Any such delay may lower our revenues and potential 
profitability. 

In addition, in order to supplement our own efforts to improve TIL manufacturing and develop TIL therapies in new indications 

in clinical trials, we currently work and collaborate with government and academic research institutions, medical institutions and 
corporate partners such as the NCI, Moffitt, Cellectis, Yale University, and Novartis. We also intend to continue to enter into 
additional third-party collaborative agreements in the future. However, we may not be able to successfully negotiate any additional 
collaborative arrangements. If established, these relationships may not be scientifically or commercially successful, or may be unable 
to enroll patients, which has occurred in one of our prior collaborations. The success of these and future collaborations and joint 
development arrangements may be subject to numerous risks and uncertainties, including the inability or unwillingness of our partners 
to perform in the manner, or to the extent anticipated, and may also be subject to disagreements regarding the rights, interests, and 
performance of the counterparties under our licenses and development agreements. Disagreements between parties to a collaboration 
arrangement regarding clinical development and commercialization matters can lead to delays in the development process or 
commercialization of the applicable product candidate and, in some cases, termination of the collaboration arrangement. These 
disagreements can be difficult to resolve if neither of the parties has final decision-making authority under the collaboration 
agreement. 

With regard to future collaboration efforts, we face significant competition in seeking appropriate collaborators. Our ability to 

reach a definitive agreement for collaboration will depend, among other things, upon our assessment of the collaborator’s resources 
and expertise, the terms and conditions of the proposed collaboration and, an evaluation by the proposed collaborator of a number of 
similar or unique factors. 

Collaborations with biopharmaceutical companies and other third parties often are terminated or allowed to expire by the other 

party. Any such termination or expiration would adversely affect us financially and could harm our business reputation. Any 
collaboration may pose a number of risks, including the following: 

• 
• 

collaborators may not perform their obligations as expected; 
collaborators may not pursue development and commercialization of any product candidates that achieve regulatory 
approval or may elect not to continue or renew development or commercialization programs based on clinical trial results, 
changes in the collaborators’ strategic focus or available funding, or external factors, such as an acquisition, that divert 
resources or create competing priorities; 

60 

• 

• 
• 

• 

• 

• 

• 

• 

• 

• 

• 

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or 
abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for 
clinical testing; 
collaborators could fail to make timely regulatory submissions for a product candidate; 
collaborators may not comply with all applicable regulatory requirements or may fail to report safety data in accordance 
with all applicable regulatory requirements; 
collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with 
our products or product candidates if the collaborators believe that competitive products are more likely to be successfully 
developed or can be commercialized under terms that are more economically attractive than ours; 
product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own 
product candidates or products, which may cause collaborators to cease to devote resources to the commercialization of our 
product candidates; 
a collaborator with marketing and distribution rights to one or more of our product candidates that achieve regulatory 
approval may not commit sufficient resources to the marketing and distribution of such product candidate or product; 
disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred 
course of development, might cause delays or termination of the research, development or commercialization of product 
candidates, might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or 
arbitration, any of which would be time consuming and expensive; 
collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information 
in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information 
or expose us to potential litigation; 
collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential 
liability; 
collaborators may be involved in a business combination, resulting in the decreased emphasis or termination of 
development or commercialization of any product candidate subject to the collaboration agreement; and 
termination of a collaboration agreement may make it more difficult to attract new collaborators and our and our products’ 
or product candidates’ reputation in the medical, business, and financial communities could be adversely affected. 

If any third-party collaborator breaches or terminates its agreement with us or fails to conduct its activities in a timely manner, 
the commercialization of our products under development could be delayed or blocked completely. It is possible that our collaborators 
will change their strategic focus, pursue alternative technologies or develop alternative products, either on their own or in 
collaboration with others, as a means for developing treatments for the diseases targeted by our collaborative programs. The 
effectiveness of our collaborators in marketing our products will also affect our revenues and earnings. 

Our collaborators will also be required to comply with the applicable regulatory requirements, and, as such, are subject to the 
same risks as we are. If they do not or are not able to comply with these requirements, we may not be able to use the data generated 
through their studies to support our future investigational or marketing applications. Collaborator noncompliance may also expose 
them and us to regulatory enforcement actions. 

No assurance can be given that we will be able to successfully collaborate with our partners as anticipated and that our current 
or future collaborations and clinical trials will be completed as contemplated, support the regulatory approval of our current product 
candidates, or result in any viable additional product candidates. For instance, to the extent that these collaborators conduct their 
studies with manufacturing processes that are different than ours or product that is different than ours, the results generated from their 
studies may not be seen in our current or future studies that employ our manufacturing processes and the results generated from their 
studies may not support approval of our product candidates. 

If we are unable to obtain or maintain suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to 
curtail the development of a product candidate, reduce or delay its development program or one or more of our other development 
programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures 
and undertake development or commercialization activities at our own expense. 

Development of a product candidate intended for use in combination with an already approved product may present more or 

different challenges than development of a product candidate for use as a single agent. 

We are currently developing lifileucel as part of a regimen which uses IL-2. We and our collaborators are also studying TIL 
therapy along with other products, such as pembrolizumab, ipilimumab and nivolumab. The development of product candidates for 

61 

use in combination with another product may present challenges. For example, the FDA may require us to use more complex clinical 
trial designs, in order to evaluate the contribution of each product and product candidate to any observed effects. It is possible that the 
results of these trials could show that any positive results are attributable to the already approved product. Moreover, following 
product approval, the FDA may require that products used in conjunction with each other be cross labeled for combined use. 
Additionally, the FDA review process can be more complicated for combination products, and may result in delays, particularly if 
complex therapeutics are involved. To the extent that we do not have rights to already approved products, this may require us to work 
with another company to satisfy such a requirement. Moreover, developments related to the already approved products may impact 
our clinical trials for the combination as well as our commercial prospects should we receive marketing approval. Such developments 
may include changes to the approved product’s safety or efficacy profile, changes to the availability of the approved product, and 
changes to the standard of care. 

A Fast Track product designation, Breakthrough Therapy designation or other designation to facilitate product candidate 

development may not lead to faster development or a faster regulatory review or approval process, and it does not increase the 
likelihood that our product candidates will receive marketing approval. 

We were granted Fast Track designation by the FDA for lifileucel in metastatic melanoma and metastatic cervical cancer. We 

were granted BTD, for lifileucel for metastatic cervical cancer and Regenerative Medicine Advanced Therapy, or RMAT, designation 
for lifileucel in advanced melanoma. We may seek Fast Track or Breakthrough designation for other of our current or future product 
candidates. Receipt of a designation to facilitate product candidate development is within the discretion of the FDA. Accordingly, 
even if we believe one of our product candidates meets the criteria for a designation, the FDA may disagree. In any event, the receipt 
of such a designation for a product candidate may not result in a faster development process, review, or approval compared to product 
candidates considered for approval under conventional the FDA procedures and does not assure ultimate marketing approval by the 
FDA. In addition, the FDA may later decide that the products no longer meet the designation conditions. 

While lifileucel has received Orphan Drug Designation, or ODD, for melanoma stages IIB-IV and for cervical cancer 
patients with tumors greater than 2 cm, there is no guarantee that we will be able to maintain this designation, receive these 
designations for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of 
exclusivity. 

We received ODD in the U.S. for lifileucel to treat malignant melanoma stages IIB-IV and cervical cancer patients with tumors 

greater than 2 cm. We may also seek ODD for our other product candidates, as appropriate. ODD, however, may be lost if the 
indication for which we develop our designated product candidates does not meet the orphan criteria. Moreover, following product 
approval, orphan exclusivity may be lost if the FDA determines, among other reasons, 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. Even if we obtain orphan exclusivity, that exclusivity may not effectively protect the product from competition because 
different products can be approved for the same condition and the same product can be approved for different conditions. Even after 
an orphan product is approved, the FDA can subsequently approve a product containing the same principal molecular features for the 
same condition if the FDA concludes that the later product is clinically superior in that it is shown to be safer or more effective or 
makes a major contribution to patient care. 

Moreover, the FDA may grant ODDs to multiple of the same products for the same indication. If another sponsor receives FDA 
approval for an ODD-designated product that is the same as our product candidates and intended for the same indication before we do, 
we would be prevented from launching our product in the U.S. for this indication for a period of at least 7 years. 

In response to a court decision regarding the plain meaning of the exclusivity provision of the Orphan Drug Act, the FDA may 

undertake a reevaluation of aspects of its orphan drug regulations and policies. We do not know if, when, or how the FDA may change 
the orphan drug regulations and policies, and it is uncertain how any changes might affect our business. Depending on what changes 
the FDA may make to its orphan drug regulations and policies, our business, financial condition, results of operations, and prospects 
could be harmed. 

As a condition of approval, the FDA may require that we implement various post-marketing requirements and conduct post-

marketing studies, any of which would require a substantial investment of time, effort, and money, and which may limit our 
commercial prospects. 

As a condition of biologic licensing, the FDA is authorized to require that sponsors of approved BLAs implement various post-
market requirements, including REMS and Phase 4 studies. For example, when the FDA approved Novartis’ Kymriah in August 2017, 

62 

a CAR-T cell therapy for the treatment of patients up to 25 years of age with B-cell precursor acute lymphoblastic leukemia, or ALL, 
that is refractory or in second or later relapse, the FDA required significant post-marketing commitments, including a Phase 4 trial, 
revalidation of a test method, and a substantial REMS program that included, among other requirements, the certification of hospitals 
and their associated clinics that dispense Kymriah, which certification includes a number of requirements, the implementation of a 
Kymriah training program, and limited distribution only to certified hospitals and their associated clinics. If we receive approval of 
our product candidates, the FDA may determine that similar or additional post-approval requirements are necessary to ensure that our 
product candidates are safe, pure, and potent. To the extent that we are required to establish and implement any post-approval 
requirements, we will likely need to invest a significant amount of time, effort, and money. Such post-approval requirements may also 
limit the commercial prospects of our product candidates. 

We may be unable to establish effective marketing and sales capabilities or enter into agreements with third parties to 

market and sell our product candidates, if they are approved, and as a result, we may be unable to generate product revenues. 

We currently have a small commercial team focused on our commercial strategy, but we do not have a commercial 
infrastructure for the marketing, sale, and distribution of biopharmaceutical products. If approved, in order to commercialize our 
products, we must build our marketing, sales, and distribution capabilities or make arrangements with third parties to perform these 
services, which will take time and require significant financial expenditures and we may not be successful in doing so. Even if we are 
able to effectively establish a sales force and develop a marketing and sales infrastructure, our sales force and marketing teams may 
not be successful in commercializing our current or future product candidates. To the extent we rely on third parties to commercialize 
any products for which we obtain regulatory approval, we would have less control over their sales efforts, and could be held liable if 
they failed to comply with applicable legal or regulatory requirements. 

We have no prior experience in the marketing, sale, and distribution of biopharmaceutical products, and there are significant 

risks involved in the building and managing of a commercial infrastructure. The establishment and development of commercial 
capabilities, including a comprehensive healthcare compliance program, to market any products we may develop will be expensive 
and time consuming and could delay any product launch, and we may not be able to successfully develop this capability. We, or our 
collaborators, will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train, manage, and retain 
marketing, sales and commercial support personnel. In the event we are unable to develop a commercial infrastructure, we may not be 
able to commercialize our current or future product candidates, which would limit our ability to generate product revenues. Factors 
that may inhibit our efforts to commercialize our current or future product candidates and generate product revenues include: 

• 

• 

• 
• 

• 
• 
• 
• 

• 
• 

• 

if the COVID-19 pandemic continues or reoccurs it may negatively impact our ability to establish commercial operations, 
educate and interact with healthcare professionals, and successfully launch our product on a timely basis; 
the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe our 
current or future product candidates; 
our inability to effectively oversee a geographically dispersed sales and marketing team; 
the costs and time associated with the initial and ongoing training of sales and marketing personnel on legal and regulatory 
compliance matters and monitoring their actions; 
an inability to secure adequate coverage and reimbursement by government and private health plans; 
the clinical indications for which the products are approved and the claims that we may make for the products; 
limitations or warnings, including distribution or use restrictions, contained in the products’ approved labeling; 
any distribution and use restrictions imposed by the FDA or to which we agree as part of a mandatory REMS or voluntary 
risk management plan; 
liability for sales or marketing personnel who fail to comply with the applicable legal and regulatory requirements; 
the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage 
relative to companies with more extensive product lines; and 
unforeseen costs and expenses associated with creating an independent sales and marketing organization or engaging a 
contract sales organization. 

If our product candidates do not achieve broad market acceptance, the revenues that we generate from their sales will be 

limited. 

We have never commercialized a product candidate for any indication. Even if our product candidates are approved by the 
appropriate regulatory authorities for marketing and sale, they may not gain acceptance among physicians, patients, third-party payors, 
and others in the medical community. If any product candidate for which we obtain regulatory approval does not gain an adequate 
level of market acceptance, we may not generate significant product revenues or become profitable. Market acceptance of our product 

63 

candidates by the medical community, patients, and third-party payors will depend on a number of factors, some of which are beyond 
our control. For example, physicians are often reluctant to switch their patients and patients may be reluctant to switch from existing 
therapies even when new and potentially more effective or safer treatments enter the market. 

Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require 
significant resources and may not be successful. If any of our product candidates is approved but does not achieve an adequate level of 
market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of 
any of our product candidates will depend on a number of factors, including: 

• 
• 
• 
• 

• 
• 
• 
• 

• 
• 

• 

• 
• 
• 
• 
• 
• 
• 

the efficacy of our product candidates; 
the prevalence and severity of adverse events associated with such product candidates; 
the clinical indications for which the products are approved and the approved claims that we may make for the products; 
limitations or warnings contained in the approved product’s FDA-required labeling, including potential limitations or 
warnings for such products that may be more restrictive than other competitive products; 
changes in the standard of care for the targeted indications for such product candidates; 
the relative difficulty of administration of such product candidates; 
cost of treatment versus economic and clinical benefit in relation to alternative treatments or therapies; 
the availability of adequate coverage or reimbursement by third parties, such as insurance companies and other healthcare 
payors, and by government healthcare programs, including Medicare and Medicaid; 
the extent and strength of our marketing and distribution of such product candidates; 
the safety, efficacy, and other potential advantages over, and availability of, alternative treatments already used or that may 
later be approved for any of our intended indications; 
distribution and use restrictions imposed by the FDA with respect to such product candidates or to which we agree as part 
of a mandatory risk evaluation and mitigation strategy or voluntary risk management plan; 
the timing of market introduction of such product candidates, as well as competitive products; 
our ability to offer such product candidates for sale at competitive prices; 
the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; 
the extent and strength of our third-party manufacturer and supplier support; 
the approval of other new products for the same indications; 
adverse publicity about the product or favorable publicity about competitive products; and 
potential product liability claims. 

Our efforts to educate the medical community and third-party payors on the benefits of our product candidates may require 
significant resources and may never be successful. Even if the medical community accepts that our product candidates are safe and 
effective for their approved indications, physicians and patients may not immediately be receptive to such product candidates and may 
be slow to adopt them as an accepted treatment of the approved indications. If our current or future product candidates are approved 
but do not achieve an adequate level of acceptance among physicians, patients, and third-party payors, we may not generate 
meaningful revenues from our product candidates, and we may not become profitable. 

Our product candidates may face competition sooner than anticipated. 

The enactment of the BPCIA created an abbreviated pathway for the approval of biosimilar and interchangeable biological 
products. The abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, 
including the possible designation of a biosimilar as “interchangeable” based on its similarity to an existing brand product. Under the 
BPCIA, the FDA cannot make an approval of an application for a biosimilar product effective until 12 years after the original branded 
product was approved under a BLA. Certain changes, however, and supplements to an approved BLA, and subsequent applications 
filed by the same sponsor, manufacturer, licensor, predecessor in interest, or other related entity do not qualify for the 12-year 
exclusivity period. 

Our product candidates may qualify for the BPCIA’s 12-year period of exclusivity. However, there is a risk that the FDA will 

not consider our product candidates to be reference products for competing products, potentially creating the opportunity for 
biosimilar competition sooner than anticipated. Additionally, this period of regulatory exclusivity does not block companies pursuing 
regulatory approval via their own traditional BLA, rather than via the abbreviated pathway. Changes may also be made to this 
exclusivity period as a result of future legislation as there has been ongoing efforts to reduce the period of exclusivity. Even if we 
receive a period of BPCIA exclusivity for our first licensed product, if subsequent products do not include a modification to the 

64 

structure of the product that impacts safety, purity, or potency, we may not receive additional periods of exclusivity for those products. 
Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference products in a way that is 
similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and 
regulatory factors that are still developing. Medicare Part B encourages use of biosimilars by paying the provider the same percentage 
of the reference product, average sale price, or ASP as a mark-up, regardless of which product is reimbursed. It is also possible that 
payors will give reimbursement preference to biosimilars even over reference biologics absent a determination of interchangeability. 

We will need to obtain FDA approval of any proposed branded product names, and any failure or delay associated with such 

approval may adversely affect our business. 

Any name we intend to use for our product candidates will require approval from the FDA regardless of whether we have 
secured a formal trademark registration from the U.S. Patent and Trademark Office, or USPTO. The FDA typically conducts a review 
of proposed product names, including an evaluation of the potential for confusion with other product names. The FDA may also object 
to a product name if it believes the name inappropriately implies medical claims or contributes to an overstatement of efficacy. If the 
FDA objects to any of our proposed product names, we may be required to adopt alternative names for our product candidates. If we 
adopt alternative names, we would lose the benefit of any existing trademark applications for such product candidate and may be 
required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable 
trademark laws, not infringe the existing rights of third parties, and be acceptable to the FDA. We may be unable to build a successful 
brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product candidates. 

Our internal computer systems, or those used by our contract research organizations or other contractors or consultants, 

may fail or suffer security breaches. 

Despite the implementation of security measures, our internal computer systems and those of our contract research 
organizations and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized and authorized 
access, natural disasters, terrorism, war and telecommunication and electrical failures. If such an event was to occur and cause 
interruptions in our operations, it could result in a disruption of our drug development programs. For example, the loss of clinical trial 
data from completed or ongoing clinical trials for a product candidate could result in delays in our regulatory approval efforts and 
significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a 
loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur 
liability and the further development of any product candidates could be delayed. 

We are dependent on information technology, systems, infrastructure and data. 

We are dependent upon information technology systems, infrastructure and data. The multitude and complexity of our 

computer systems make them inherently vulnerable to service interruption or destruction, malicious intrusion and random attack. 
Likewise, data privacy or security breaches by third parties, employees, contractors or others may pose a risk that sensitive data, 
including our intellectual property, trade secrets or personal information of our employees, patients, or other business partners may be 
exposed to unauthorized persons or to the public. Cyberattacks are increasing in their frequency, sophistication and intensity. 
Cyberattacks could include the deployment of harmful malware, denial-of-service, ransomware, social engineering and other means to 
affect service reliability and threaten data confidentiality, privacy, integrity and availability. Our business and technology partners face 
similar risks and any security breach of their systems could adversely affect our security posture. While we have invested, and 
continue to invest, in the protection of our data and information technology infrastructure, there can be no assurance that our efforts, or 
the efforts of our partners and vendors, will prevent service interruptions, or identify breaches in our systems, that could adversely 
affect our business and operations and/or result in the loss of critical or sensitive information, which could result in financial, legal, 
business or reputational harm to us. In addition, our liability insurance may not be sufficient in type or amount to cover us against 
claims related to security breaches, cyberattacks and other related breaches. 

Our business could be adversely affected by the effects of health epidemics, including the recent spread of the COVID-19 

pandemic, in regions where we or third parties on which we rely have significant manufacturing facilities, concentrations of 
clinical trial sites or other business operations. The COVID-19 pandemic could materially affect our operations, including at our 
headquarters in San Carlos, California, at our manufacturing facility in Philadelphia, Pennsylvania, and at our clinical trial sites, 
as well as the business or operations of our other manufacturers, CROs or other third parties with whom we conduct business. 

Our business could be adversely affected by health epidemics in regions where we have offices, manufacturing facilities, 

concentrations of clinical trial sites or other business operations, and could cause significant disruption in the operations of clinical 

65 

trial sites, third party manufacturers and CROs upon whom we rely. For example, starting in December 2019, a novel strain of 
coronavirus (“COVID-19”) was reported to have surfaced in Wuhan, China and has spread to multiple countries, including the U.S. 
and several European countries. In March 2020, the World Health Organization declared COVID-19 a global pandemic and the U.S. 
declared the COVID-19 pandemic a national emergency. Similarly, during that time, the State of California declared a state of 
emergency related to the spread of the COVID-19 pandemic and the health officers of six San Francisco Bay Area counties, including 
San Mateo County where our headquarters in San Carlos is located, issued shelter-in-place orders. In addition, on March 19, 2020, the 
Governor of California and the State Public Health Officer and Director of the California Department of Public Health ordered all 
individuals living in the State of California to stay at their place of residence for an indefinite period of time (subject to certain 
exceptions to facilitate authorized necessary activities) to mitigate the impact of the COVID-19 pandemic. Similar executive orders 
have been issued by state and local governments in Pennsylvania, Florida, and elsewhere, and states of emergency have been declared 
at the state and local level in most jurisdictions throughout the U.S. 

Quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns or other restrictions 

on the conduct of business operations could occur, related to the COVID-19 pandemic or other infectious diseases could impact 
personnel at third-party manufacturing facilities in the U.S. and other countries, or the availability or cost of materials, which would 
disrupt our supply chain. In addition, our clinical trials may be affected by the COVID-19 pandemic. Clinical site initiation, patient 
enrollment and patient monitoring may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic. Some 
sites may no longer be available to see patients for clinical trials.  Some patients may not be able to comply with clinical trial protocols 
if quarantines impede patient movement or interrupt healthcare services. Patients may also miss follow-up visits after receiving our 
therapies during our clinical trials, which may or may not be rectified by future patient visits and which may result in the exclusion of 
data from such patients from the clinical trial data. Similarly, our ability to recruit and retain patients and principal investigators and 
site staff who, as healthcare providers, may have heightened exposure to the virus that causes the COVID-19 pandemic and adversely 
impact our clinical trial operations. The COVID-19 pandemic may also affect our ability to recruit treatment-naïve patients into our 
clinical trials, because those patients may be more likely to seek standard of care therapies available at local treatment centers rather 
than enroll in a clinical trial at a larger hospital. 

We continue to monitor the impact, if any, of the COVID-19 pandemic on our current and future operations, including our 

regulatory filing timelines and strategy as well as our preparation for commercial launch. It is unclear the extent to which the COVID-
19 pandemic (including future variants) will impact our business, results of operations, financial condition and our future strategic 
plans as future developments of the outbreak are highly uncertain and cannot be predicted. New information is constantly emerging 
concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others. As the COVID-19 
pandemic continues for an extended period of time, and with travel, face to face interactions, and resources are not allowed or are 
severely limited, either by us or our contractors, including our CMOs, our regulatory strategy, BLA filing timelines, or commercial 
launch preparations may be negatively impacted. The COVID-19 pandemic may also impact the FDA and their ability to timely 
review our regulatory filings and conduct the pre-approval inspections necessary for ultimate approval of BLA. We cannot predict at 
this time whether and how FDA operations may be impacted at relevant times for our planned regulatory submissions. 

Our failure to comply with international data protection laws and regulations could lead to government enforcement actions 

and significant penalties against us, and adversely impact our operating results. 

European Union, or EU, member states and other foreign jurisdictions, including Switzerland, the United Kingdom and 

Canada, have adopted data protection laws and regulations which impose significant compliance obligations on us. Moreover, the 
collection and use of personal health data in the EU, which was formerly governed by the provisions of the EU Data Protection 
Directive, was replaced with the EU General Data Protection Regulation, or the GDPR, in May 2018. The GDPR, which is wide-
ranging in scope, imposes several requirements relating to the consent of the individuals to whom the personal data relates, the 
information provided to the individuals, the security and confidentiality of the personal data, data breach notification and the use of 
third-party processors in connection with the processing of personal data. The GDPR also imposes strict rules on the transfer of 
personal data out of the EU to the U.S., provides an enforcement authority and imposes large penalties for noncompliance, including 
the potential for fines of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. 
The GDPR requirements apply not only to third-party transactions, but also to transfers of information between us and our 
subsidiaries. The implementation of the GDPR has increased our responsibility and liability in relation to personal data that we 
process, including in clinical trials, and we may in the future be required to put in place additional mechanisms to ensure compliance 
with the GDPR, which could divert management’s attention and increase our cost of doing business. In addition, new regulation or 
legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of doing 
business. If we fail to comply with the data protection laws in any EU member country or other jurisdiction, the data protection 
authority of such country or other jurisdiction may, in addition to fines, impose sanctions on us, which may include a prohibition that 

66 

prevents us from transferring and/or processing personal data of data subjects from such country or other jurisdiction for a duration 
determined by the sanctioning authority. Our inability to transfer and/or process personal data of data subjects could preclude us from 
conducting clinical trials of our products in the EU member country or other jurisdiction for the duration of the sanction. Our inability 
to conduct clinical trials in the EU member country or other jurisdiction for the duration of the sanction may delay and increase the 
cost of development of our products, with a material adverse effect on our business. In this regard, we expect that there will continue 
to be new proposed laws, regulations and industry standards relating to privacy and data protection in the U.S., the EU and other 
jurisdictions, and we cannot determine the impact such future laws, regulations and standards may have on our business. 

Our failure to comply with state and/or national data protection laws and regulations could lead to government enforcement 

actions and significant penalties against us, and adversely impact our operating results. 

There are numerous other laws and legislative and regulatory initiatives at the federal and state levels addressing privacy and 
security concerns, and some state privacy laws apply more broadly than the Health Insurance Portability and Accountability Act, or 
HIPAA, and associated regulations. For example, California recently enacted legislation, the California Consumer Privacy Act, or 
CCPA, which went into effect January 1, 2020 and was recently amended and expanded by the California Privacy Rights Act, or 
CPRA, which will take effect on January 1, 2023. The CCPA and CPRA, among other things, create new data privacy obligations for 
covered companies and provides new privacy rights to California residents, including the right to opt out of certain disclosures of their 
information. The CCPA also created a private right of action with statutory damages for certain data breaches, thereby potentially 
increasing risks associated with a data breach.  

Although the law includes limited exceptions, including for certain information collected as part of clinical trials as specified in 

the law, it may regulate or impact our processing of personal information depending on the context. It remains unclear what, if any, 
additional modifications will be made to the CPRA by the California legislature or how it will be interpreted. Therefore, the effects of 
the CCPA and CPRA are significant and will likely require us to modify our data processing practices, and may cause us to incur 
substantial costs and expenses to comply.   

We will need to grow the size and capabilities of our organization, and we may experience difficulties in managing this 

growth. 

Our operations are dependent upon the services of our executives and our employees who are engaged in research and 
development. The loss of the services of our executive officers or senior research personnel could delay our product development 
programs and our research and development efforts. In order to develop our business in accordance with our business plan, we will 
have to hire additional qualified personnel, including in the areas of research, manufacturing, clinical trials management, regulatory 
affairs, and sales and marketing. We are continuing our efforts to recruit and hire the necessary employees to support our planned 
operations in the near term. For example, we continue to recruit for a new Chief Executive Officer. However, competition for 
qualified employees among companies in the biotechnology and biopharmaceutical industry is intense, and no assurance can be given 
that we will be able attract, hire, retain and motivate the highly skilled employees that we need. Future growth will impose significant 
added responsibilities on members of management, including: 

identifying, recruiting, integrating, maintaining, and motivating additional employees; 

• 
•  managing our internal development efforts effectively, including the clinical and FDA review process for our product 

candidates, while complying with our contractual obligations to contractors and other third parties; and 
improving our operational, financial and management controls, reporting systems, and procedures. 

• 

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to 

effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away 
from day-to-day activities in order to devote a substantial amount of time to managing these growth activities. 

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, 

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

67 

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and 

contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product 
candidates and, accordingly, may not achieve our research, development, and commercialization goals on a timely basis, or at all. 

If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our 

stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks. 

We may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, 

intellectual property rights, technologies, or businesses. Any potential acquisition or strategic partnership may entail numerous risks, 
including: 

• 
• 
• 
• 

• 

• 

• 

• 

increased operating expenses and cash requirements; 
the assumption of additional indebtedness or contingent liabilities; 
the issuance of our equity securities; 
assimilation of operations, intellectual property and products of an acquired company or product, including difficulties 
associated with integrating new personnel; 
the diversion of our management’s attention from our existing product programs and initiatives in pursuing such a strategic 
merger or acquisition; 
retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business 
relationships; 
risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their 
existing products or product candidates and regulatory approvals; and 
our inability to generate revenue from acquired technology and/or products sufficient to meet our objectives in undertaking 
the acquisition or even to offset the associated acquisition and maintenance costs. 

Depending on the size and nature of future strategic acquisitions, we may acquire assets or businesses that require us to raise 

additional capital or to operate or manage businesses in which we have limited experience. Making larger acquisitions that require us 
to raise additional capital to fund the acquisition will expose us to the risks associated with capital raising activities. Acquiring and 
thereafter operating larger new businesses will also increase our management, operating and reporting costs and burdens. In addition, 
if we undertake acquisitions, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses and 
acquire intangible assets that could result in significant future amortization expense. Moreover, we may not be able to locate suitable 
acquisition opportunities and this inability could impair our ability to grow or obtain access to technology or products that may be 
important to the development of our business. 

We may rely on third parties to perform many essential services for any products that we commercialize, including services 

related to distribution, government price reporting, customer service, accounts receivable management, cash collection, and 
adverse event reporting. If these third parties fail to perform as expected or to comply with legal and regulatory requirements, our 
ability to commercialize our current or future product candidates will be significantly impacted and we may be subject to 
regulatory sanctions. 

We may retain third-party service providers to perform a variety of functions related to the sale and distribution of our current 
or future product candidates, key aspects of which will be out of our direct control. These service providers may provide key services 
related to distribution, customer service, accounts receivable management, and cash collection. If we retain a service provider, we 
would substantially rely on it as well as other third-party providers that perform services for us, including entrusting our inventories of 
products to their care and handling. If these third-party service providers fail to comply with applicable laws and regulations, fail to 
meet expected deadlines, or otherwise do not carry out their contractual duties to us, or encounter physical or natural damage at their 
facilities, our ability to deliver product to meet commercial demand would be significantly impaired and we may be subject to 
regulatory enforcement action. 

In addition, we may engage third parties to perform various other services for us relating to adverse event reporting, safety 
database management, fulfillment of requests for medical information regarding our product candidates and related services. If the 
quality or accuracy of the data maintained by these service providers is insufficient, or these third parties otherwise fail to comply with 
regulatory requirements related to adverse event reporting, we could be subject to regulatory sanctions. 

Additionally, we may contract with a third-party to calculate and report pricing information mandated by various government 
programs. If a third party fails to timely report or adjust prices as required or errs in calculating government pricing information from 

68 

transactional data in our financial records, it could impact our discount and rebate liability, and potentially subject us to regulatory 
sanctions or False Claims Act lawsuits. 

Risks Related to Government Regulation 

The FDA regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the 

clinical development and regulatory approval of our product candidates. 

We have not previously submitted a BLA to the FDA, or similar approval filings to comparable foreign authorities. A BLA 

must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and 
effectiveness for each desired indication. For example, following our End of Phase 2 meeting with the FDA, we increased enrollment 
in Cohort 1 of our ongoing C-145-04 clinical trial of TIL therapy lifileucel to at least 75 patients of the appropriate population to 
address the expected sample size in anticipation of a BLA submission in 2021. Additionally, the patient population is defined per the 
discussion with FDA as patients who have progressed following initial systemic therapy for recurrent or metastatic disease which 
include many of the more advanced patients enrolled to date. Our current beliefs regarding the registration pathway for the lifileucel 
product candidate in metastatic cervical cancer are based on our interpretation of communications with the FDA to date and our efforts 
to address such communications, which may be incorrect. Our statements that the study may support a BLA submission also assume 
that our as-adjusted study has addressed the additional requests by the FDA that were raised at our End of Phase 2 meeting. Further, 
enrollment in this study may need to be further adjusted based on future feedback from the FDA, changes in the competitive 
environment, or other regulatory agency input. The revised protocol which further defines the patient population to include more 
advanced patients in the study, may have an adverse effect on the results reported to date, changes to implement an independent 
review committee and assay validation and implementation, and the data within this study may not ultimately be supportive of product 
approval, all of which could result in significant delays to our currently anticipated timeline for development and approval of our 
product candidate or prevent its approval entirely. Similarly, our current beliefs for our lifileucel product candidate for the treatment of 
melanoma are based on our interpretation of communications received from the FDA to date regarding this product candidate and our 
ongoing C-144-01 clinical trial, and may also be incorrect. 

A BLA must also include significant information regarding the chemistry, manufacturing and controls for the product. 
Additionally, we expect the novel nature of our product candidates to create further challenges in obtaining regulatory approval. For 
example, the FDA has limited experience with commercial development of cell therapies for cancer. We may also not be able to 
successfully utilize the BTD or RMAT designations we have received for metastatic cervical cancer and advanced melanoma, 
respectively, to successfully complete the development and commercialization of lifileucel. We may not be able to reach agreement 
with FDA on an interpretation of outcomes from our meetings, including meetings we have held with FDA in relation to our C-145-04 
and C-144-01 clinical trials and future meetings. For example, on October 5, 2020, we announced that we and the FDA have not been 
able to agree on the required potency assays to fully define our TIL therapy, which is required as part of a BLA submission, and that 
as a result of these developments, our BLA submission was not expected by the end of 2020 and was anticipated to occur in 2021. 
Previously, we reported the submission of assay data to the FDA, and on May 18, 2021, we announced that we had received 
regulatory feedback from the FDA regarding our potency assays for lifileucel. Following FDA feedback regarding the potency assays 
for lifileucel, we have continued ongoing work developing and validating our potency assays and have engaged in discussions with the 
FDA during the second half of 2021. Our BLA submission for lifileucel is now expected to occur during the first half of 2022. 
Accordingly, the regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and 
approval may not be obtained. 

We may also experience delays, including delays arising from the need to increase enrollment, in completing planned clinical 

trials for a variety of reasons, including delays related to: 

• 
• 

the availability of financial resources to commence and complete the planned trials; 
reaching agreement on acceptable contract terms with prospective CROs and clinical trial sites, the terms of which can be 
subject to extensive negotiation and may vary significantly among different CROs and trial sites; 
obtaining approval at each clinical trial site by an independent IRB, or central IRB; 
recruiting suitable patients to participate in a trial; 
having patients complete a trial or return for post-treatment follow-up; 
clinical trial sites deviating from trial protocol or dropping out of a trial; 
adding new clinical trial sites; 

• 
• 
• 
• 
• 
•  manufacturing sufficient quantities of qualified materials under cGMPs and applying them on a subject-by-subject basis for 

use in clinical trials; or 

69 

• 

timely implementing or validating changes to our manufacturing or quality control processes and methods needed to 
address FDA feedback. 

We could also encounter delays if there are unresolved ethical issues associated with physicians enrolling patients in clinical 
trials of our product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a 
clinical trial may be suspended or terminated by us, the IRBs for the institutions in which such trials are being conducted by the FDA 
or other regulatory authorities, or recommended for suspension or termination by DSMBs due to a number of factors, including failure 
to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial 
operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, including as a result of 
genetic editing methods, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product 
candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If 
we experience termination of, or delays in the completion of, any clinical trial of our product candidates, the commercial prospects for 
our product candidates will be harmed, and our ability to generate product revenue will be delayed. In addition, any delays in 
completing our clinical trials will increase our costs, slow down our product development and approval process and jeopardize our 
ability to commence product sales and generate revenue. 

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be 

successful in obtaining regulatory approval of our product candidates in other jurisdictions. 

In order to market and sell our products outside the U.S., we or our third-party collaborators may be required to obtain separate 
marketing approvals and comply with numerous and varying regulatory requirements. Obtaining and maintaining regulatory approval 
of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any 
other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the 
regulatory approval process in others. Approval policies and requirements may vary among jurisdictions. For example, even if the 
FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve 
the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among 
jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the U.S., 
including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by 
regulatory authorities in other jurisdictions. In many jurisdictions outside the U.S., a product candidate must be approved for 
reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products 
is also subject to approval. We or our collaborators may not be able to file for regulatory approval of our product candidates in 
international jurisdictions or obtain approvals from regulatory authorities outside the U.S. on a timely basis, if at all. 

We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the U.S. have 

requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining 
foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and 
costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory 
requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability 
to realize the full market potential of our product candidates will be harmed. 

We are, and if we receive regulatory approval of our product candidates, will continue to be subject to ongoing regulatory 

obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties 
if we fail to comply with regulatory requirements or experience unanticipated problems with our product candidates. 

Any regulatory approvals that we receive for our product candidates will require ongoing surveillance to monitor the safety and 

efficacy of the product candidate. The FDA may also require a REMS to approve our product candidates, which could entail 
requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted 
distribution methods, patient registries and other risk minimization tools. The FDA may also require post-approval Phase 4 studies. 
Moreover, the FDA and comparable foreign regulatory authorities will continue to closely monitor the safety profile of any product 
even after approval. If the FDA or comparable foreign regulatory authorities become aware of new safety information after approval 
of any of our product candidates, they may withdraw approval, require labeling changes or establishment of a REMS or similar 
strategy, impose significant restrictions on a product’s indicated uses or marketing, or impose ongoing requirements for potentially 
costly post-approval studies or post-market surveillance. Any such restrictions could limit sales of the product. 

In addition, we, our contractors, and our collaborators are and will remain responsible for FDA compliance, including 
requirements related to product design, testing, clinical and pre-clinical trials approval, manufacturing processes and quality, labeling, 

70 

packaging, distribution, adverse event and deviation reporting, storage, advertising, marketing, promotion, sale, import, export, 
submissions of safety and other post-marketing information and reports such as deviation reports, establishment registration, product 
listing, annual user fees, and recordkeeping for our product candidates. We and any of our collaborators, including our contract 
manufacturers, could be subject to periodic unannounced inspections by the FDA to monitor and ensure compliance with regulatory 
requirements. Application holders must further notify the FDA, and depending on the nature of the change, obtain FDA pre-approval 
for product and manufacturing changes. The cost of compliance with post-approval regulations may have a negative effect on our 
operating results and financial condition. 

Later discovery of previously unknown problems with our product candidates, including adverse events of unanticipated 
severity or frequency, that the product is less effective than previously thought, problems with our third-party manufacturers or 
manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things: 

• 

• 

restrictions on the marketing, distribution, or manufacturing of our product candidates, withdrawal of the product from the 
market, or voluntary or mandatory product recalls; 
restrictions on the labeling of our product candidates, including required additional warnings, such as black box warnings, 
contraindications, precautions, and restrictions on the approved indication or use; 

•  modifications to promotional pieces; 
• 
• 
• 
• 

changes to product labeling or the way the product is administered; 
liability for harm caused to patients or subjects; 
fines, restitution, disgorgement, warning letters, untitled letters, or holds on or termination of clinical trials; 
refusal by the FDA to approve pending applications or supplements to approved applications filed by us or suspension or 
revocation of license approvals; 
product seizure or detention, or refusal to permit the import or export of our product candidates; 
injunctions or the imposition of civil or criminal penalties, including imprisonment; 

• 
• 
•  FDA debarment, debarment from government contracts, and refusal of future orders under existing contracts, exclusion 

from federal healthcare programs, consent decrees, or corporate integrity agreements; 
regulatory authority issuance of safety alerts, Dear Healthcare Provider letters, press releases, or other communications 
containing warnings or other safety information about the biologic; 
reputational harm; or 
the product becoming less competitive. 

• 

• 
• 

Any of these events could further have other material and adverse effects on our operations and business and could adversely 

impact our stock price and could significantly harm our business, financial condition, results of operations, and prospects. 

The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that 

could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of 
government regulation that may arise from future legislation or administrative action, either in the U.S. or abroad. If we are slow or 
unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain 
regulatory compliance, we may lose any marketing approval that we may have obtained, be subject to other regulatory enforcement 
action, and we may not achieve or sustain profitability. 

If we fail to comply with federal and state healthcare and promotional laws, including fraud and abuse and information 
privacy and security laws, we could face substantial penalties and our business, financial condition, results of operations, and 
prospects could be adversely affected. 

As a biopharmaceutical company, we are subject to many federal and state healthcare laws, including the federal AKS, the 

federal civil and criminal FCA, the civil monetary penalties statute, the Medicaid Drug Rebate statute and other price reporting 
requirements, the Veterans Health Care Act of 1992, the federal Health Insurance Portability and Accountability Act of 1996 (as 
amended by the Health Information Technology for Economics and Clinical Health Act), the Foreign Corrupt Practices Act of 1977, 
the Patient Protection and Affordable Care Act of 2010, and similar state laws. Even though we do not and will not control referrals of 
healthcare services or bill directly to Medicare, Medicaid, or other third-party payors, certain federal and state healthcare laws and 
regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. If we do not comply with all 
applicable fraud and abuse laws, we may be subject to enforcement by both the federal government and the states in which we conduct 
our business. 

71 

Laws and regulations require calculation and reporting of complex pricing information for prescription drugs, and compliance 

will require us to invest in significant resources and develop a price reporting infrastructure, or depend on third parties to compute and 
report our drug pricing. Pricing reported to CMS must be certified. Non-compliant activities expose us to FCA risk if they result in 
overcharging agencies, underpaying rebates to agencies, or causing agencies to overpay providers. 

If we or our operations are found to be in violation of any federal or state healthcare law, or any other governmental regulations 
that apply to us, we may be subject to penalties, including civil, criminal, and administrative penalties, damages, fines, disgorgement, 
debarment from government contracts, refusal of orders under existing contracts, exclusion from participation in U.S. federal or state 
health care programs, corporate integrity agreements, and the curtailment or restructuring of our operations, any of which could 
materially adversely affect our ability to operate our business and our financial results. If any of the physicians or other healthcare 
providers or entities with whom we expect to do business, including our collaborators, is found not to be in compliance with 
applicable laws, they may be subject to criminal, civil, or administrative sanctions, including but not limited to, exclusions from 
participation in government healthcare programs, which could also materially affect our business. 

In particular, if we are found to have impermissibly promoted any of our product candidates, we may become subject to 
significant liability and government fines. We, and any of our collaborators, must comply with requirements concerning advertising 
and promotion for any of our product candidates for which we or they obtain marketing approval. Promotional communications with 
respect to therapeutics are subject to a variety of legal and regulatory restrictions and continuing review by the FDA, Department of 
Justice, Department of Health and Human Services’ Office of Inspector General, state attorneys general, members of Congress, and 
the public. When the FDA or comparable foreign regulatory authorities issue regulatory approval for a product candidate, the 
regulatory approval is limited to those specific uses and indications for which a product is approved. If we are not able to obtain FDA 
approval for desired uses or indications for our products and product candidates, we may not market or promote our products for those 
indications and uses, referred to as off-label uses, and our business may be adversely affected. We further must be able to sufficiently 
substantiate any claims that we make for our products including claims comparing our products to other companies’ products and 
must abide by the FDA’s strict requirements regarding the content of promotion and advertising. 

While physicians may choose to prescribe products for uses that are not described in the product’s labeling and for uses that 

differ from those tested in clinical studies and approved by the regulatory authorities, we are prohibited from marketing and promoting 
the products for indications and uses that are not specifically approved by the FDA. These off-label uses are common across medical 
specialties and may constitute an appropriate treatment for some patients in varied circumstances. Regulatory authorities in the U.S. 
generally do not restrict or regulate the behavior of physicians in their choice of treatment within the practice of medicine. Regulatory 
authorities do, however, restrict communications by biopharmaceutical companies concerning off-label use. 

The FDA and other agencies actively enforce the laws and regulations regarding product promotion, particularly those 
prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted a product may be subject to 
significant sanctions. The federal government has levied large civil and criminal fines against companies for alleged improper 
promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies 
enter into consent decrees of permanent injunctions under which specified promotional conduct is changed or curtailed. Thus, we and 
any of our collaborators will not be able to promote any products we develop for indications or uses for which they are not approved. 

In the U.S., engaging in the impermissible promotion of our products, following approval, for off-label uses can also subject us 
to false claims and other litigation under federal and state statutes, including fraud and abuse and consumer protection laws, which can 
lead to civil and criminal penalties and fines, agreements with governmental authorities that materially restrict the manner in which we 
promote or distribute therapeutic products and do business through, for example, corporate integrity agreements, suspension or 
exclusion from participation in federal and state healthcare programs, and debarment from government contracts and refusal of future 
orders under existing contracts. These false claims statutes include the federal civil False Claims Act, which allows any individual to 
bring a lawsuit against a biopharmaceutical company on behalf of the federal government alleging submission of false or fraudulent 
claims or causing others to present such false or fraudulent claims, for payment by a federal program such as Medicare or Medicaid. If 
the government decides to intervene and prevails in the lawsuit, the individual will share in the proceeds from any fines or settlement 
funds. If the government declines to intervene, the individual may pursue the case alone. These False Claims Act lawsuits against 
manufacturers of drugs and biologics have increased significantly in volume and breadth, leading to several substantial civil and 
criminal settlements, up to $3.0 billion, pertaining to certain sales practices and promoting off-label uses. In addition, False Claims 
Act lawsuits may expose manufacturers to follow-on claims by private payors based on fraudulent marketing practices. This growth in 
litigation has increased the risk that a biopharmaceutical company will have to defend a false claim action, pay settlement fines or 
restitution, as well as criminal and civil penalties, agree to comply with burdensome reporting and compliance obligations, and be 
excluded from Medicare, Medicaid, or other federal and state healthcare programs. If we or our future collaborators do not lawfully 

72 

promote our approved products, if any, we may become subject to such litigation and, if we do not successfully defend against such 
actions, those actions may have a material adverse effect on our business, financial condition, results of operations and prospects. 

Although an effective compliance program can mitigate the risk of investigation and prosecution for violations of these laws, 
the risks cannot be entirely eliminated. Moreover, achieving and sustaining compliance with applicable federal and state fraud laws 
may prove costly. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur 
significant legal expenses and divert our management’s attention from the operation of our business. 

Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, which 

could make it difficult for us to sell our product candidates profitably. 

In both domestic and foreign markets, sales of our product candidates, if approved, depend on the availability of coverage and 
adequate reimbursement from third-party payors. Such third-party payors include government health programs such as Medicare and 
Medicaid, managed care providers, private health insurers, and other organizations. In addition, because our product candidates 
represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenue from our product candidates. 

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. Obtaining coverage and adequate reimbursement from governmental healthcare programs, 
such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. 

Government authorities and third-party payors decide which drugs and treatments they will cover and the amount of 
reimbursement. 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. If reimbursement is not 
available, or is available only to limited levels, our product candidates may be competitively disadvantaged, and we, or our 
collaborators, may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved 
reimbursement amount may not be high enough to allow us, or our collaborators, to establish or maintain a market share sufficient to 
realize a sufficient return on our or their investments. Alternatively, securing favorable reimbursement terms may require us to 
compromise pricing and prevent us from realizing an adequate margin over cost. Reimbursement by a third-party payor may depend 
upon a number of factors, including, but not limited to, 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. 

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 us to provide to the payor supporting scientific, clinical and cost-effectiveness data 
for the use of our products. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be 
adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Moreover, the 
factors noted above have continued to be the focus of policy and regulatory debate that has, thus far, shown the potential for 
movement towards permanent policy changes; this trend is apt to continue, and may result in more or less favorable impacts on 
pricing. Patients are unlikely to use our product candidates unless coverage is provided, and reimbursement is adequate to cover a 
significant portion of the cost of our product candidates. 

In the U.S., no uniform policy of coverage and reimbursement for products exists among third-party payors. Therefore, 
coverage and reimbursement for products can differ significantly from payor to payor. As a result, the coverage determination process 
is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our product 
candidates to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. 

Prices paid for a drug also vary depending on the class of trade. Prices charged to government customers are subject to price 

controls, including ceilings, and private institutions obtain discounts through group purchasing organizations. Net prices for drugs may 
be further reduced by mandatory discounts or rebates required by government healthcare programs and demanded by private payors. It 
is also not uncommon for market conditions to warrant multiple discounts to different customers on the same unit, such as purchase 
discounts to institutional care providers and rebates to the health plans that pay them, which reduces the net realization on the original 
sale. 

73 

In addition, federal programs impose penalties on manufacturers of drugs marketed under an NDA or BLA, in the form of 

mandatory additional rebates and/or discounts if commercial prices increase at a rate greater than the Consumer Price Index-Urban, 
and these rebates and/or discounts, which can be substantial, may impact our ability to raise commercial prices. Regulatory authorities 
and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular 
medications, which could affect our ability or that of our collaborators to sell our product candidates profitably. These payors may not 
view our products, if any, as cost-effective, and coverage and reimbursement may not be available to our customers, or those of our 
collaborators, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost control initiatives 
could cause us, or our collaborators, to decrease, discount, or rebate a portion of the price we, or they, might establish for products, 
which could result in lower than anticipated product revenues. If the realized prices for our products, if any, decrease or if 
governmental and other third-party payors do not provide adequate coverage or reimbursement, our prospects for revenue and 
profitability will suffer. Moreover, the recent and ongoing series of congressional hearings relating to drug pricing has presented 
heightened attention to the biopharmaceutical industry, creating the potential for political and public pressure, while the potential for 
resulting legislative or policy changes presents uncertainty. 

Assuming coverage is approved, the resulting reimbursement payment rates might not be adequate. If payors subject our 
product candidates to maximum payment amounts or impose limitations that make it difficult to obtain reimbursement, providers may 
choose to use therapies which are less expensive when compared to our product candidates. Additionally, if payors require high 
copayments, beneficiaries may decline prescriptions and seek alternative therapies. We may need to conduct post-marketing studies in 
order to demonstrate the cost-effectiveness of any future products to the satisfaction of hospitals and other target customers and their 
third-party payors. Such studies might require us to commit a significant amount of management time and financial and other 
resources. Our future products might not ultimately be considered cost-effective. Adequate third-party coverage and reimbursement 
might not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product 
development. 

Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated 

methods of controlling healthcare costs. In addition, third-party payors are requiring higher levels of evidence of the benefits and 
clinical outcomes of new technologies and are challenging the prices charged. We, and our collaborators, cannot be sure that coverage 
will be available for any product candidate that we, or they, commercialize and, if available, that the reimbursement rates will be 
adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to laws that 
presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. An inability to promptly 
obtain coverage and adequate payment rates from both government-funded and private payors for any our product candidates for 
which we obtain marketing approval could have a material adverse effect on our operating results, our ability to raise capital needed to 
commercialize products, and our overall financial condition. 

There have been, and likely will continue to be, legislative and regulatory proposals at the federal and state levels directed at 

broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives that may 
be adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations and other payors 
of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect: 

• 
• 
• 
• 
• 

the demand for our product candidates if we obtain regulatory approval; 
our ability to set a price that we believe is fair for our products; 
our ability to generate revenue and achieve or maintain profitability; 
the level of taxes that we are required to pay; and 
the availability of capital. 

Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments 

from private payors, which may adversely affect our future profitability. A particular challenge for our product candidates arises from 
the fact that they will primarily be used in an inpatient setting. Inpatient reimbursement generally relies on stringent packaging rules 
that may mean that there is no separate payment for our product candidates. Additionally, data used to set the payment rates for 
inpatient admissions is usually several years old and would not take into account all of the additional therapy costs associated with the 
administration of our product candidates. If special rules are not created for reimbursement for immunotherapy treatments such as our 
product candidates, hospitals might not receive enough reimbursement to cover their costs of treatment, which will have a negative 
effect on their adoption of our product candidates. 

74 

We are subject to new legislation, regulatory proposals, and healthcare payor initiatives that may increase our costs of 

compliance, and adversely affect our ability to market our products, obtain collaborators, and raise capital. 

In the U.S. and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed 
changes regarding the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate 
post-approval activities, and affect our ability, or the ability of our collaborators, to profitably sell any products for which we obtain 
marketing approval. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may 
result in more rigorous coverage criteria and in additional downward pressure on the price that we, or our collaborators, may receive 
for any approved products. 

Since enactment of the Patient Protection and Affordable Care Act, as amended (the “ACA”) in 2010, in both the U.S. and 

certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could 
impact our ability to sell our products profitably. In August 2011, the Budget Control Act of 2011, among other things, created 
measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted 
deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the 
legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to 
providers up to 2% per fiscal year, which went into effect on April 1, 2013 and were to remain in effect until 2024. The Bipartisan 
Budget Act of 2015 extended the 2% sequestration to 2025. In January 2013, the American Taxpayer Relief Act of 2012, or ATRA, 
was approved which, among other things, reduced Medicare payments to several providers, with primary focus on the hospital 
outpatient setting and ancillary services, 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. On January 20, 2017, the new 
administration signed an Executive Order directing federal agencies with authorities and responsibilities under the ACA to waive, 
defer, grant exemptions from, or delay the implementation of any provision of the ACA that would impose a fiscal or regulatory 
burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices, and, for 
that reason, some final regulations have yet to take effect. In December 2017, Congress repealed the individual mandate for health 
insurance required by the ACA and could consider further legislation to repeal other elements of the ACA. At the end of 2017, CMS 
promulgated regulations that reduce the amount paid to hospitals for outpatient drugs purchased under the 340B program, and some 
states have enacted transparency laws requiring manufacturers to report information on drug prices and price increases. In June 2021, 
the Supreme Court issued its opinion in California v. Texas, upholding the constitutionality of the ACA.  

Additional federal and state healthcare reform measures may be adopted in the future that may result in more rigorous coverage 

criteria, increased regulatory burdens and operating costs, decreased net revenue from our pharmaceutical products, decreased 
potential returns from our development efforts, and additional downward pressure on the price that we receive for any approved drug. 
Any reduction in reimbursement from Medicare or other government healthcare programs may result in a similar reduction in 
payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from 
being able to generate revenue, attain profitability or commercialize our products. 

Legislative and regulatory proposals may also be made to expand post-approval requirements and restrict sales and promotional 

activities for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, 
guidance, or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product 
candidates, if any, may be. In addition, increased scrutiny by Congress of the FDA’s approval process may significantly delay or 
prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other 
requirements. 

In addition, there have been a number of other policy, legislative and regulatory proposals aimed at changing the 

pharmaceutical industry. The U.S. government, state legislatures and foreign governmental entities have shown significant interest in 
implementing cost containment programs to limit the growth of government-paid healthcare costs, including price controls, 
restrictions on reimbursement and coverage and requirements for substitution of generic products for branded prescription drugs. 
Adoption of government controls and measures, and tightening of restrictive policies in jurisdictions with existing controls and 
measures, could exclude or limit our product candidates from coverage and limit payments for pharmaceuticals. Under the Biden 
Administration’s Build Back Better Agenda, for example, Medicare negotiation of prescription drug costs with biopharmaceutical 
companies is proposed to lower prescription drug costs We continue to monitor the potential impact of these and other  proposals to 
lower prescription drug costs at the federal and state level. 

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 

75 

product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from 
other countries and bulk purchasing. 

We are unable to predict the future course of federal or state healthcare legislation in the U.S. directed at broadening the 
availability of healthcare and containing or lowering the cost of healthcare. The ACA and any further changes in the law or regulatory 
framework that reduce our revenue or increase our costs could also have a material and adverse effect on our business, financial 
condition and results of operations. 

Governments outside the U.S. tend to impose strict price controls, which may adversely affect our revenues, if any. 

In international markets, reimbursement and health care payment systems vary significantly by country, and many countries 

have instituted price ceilings on specific products and therapies. In some countries, particularly the countries of the EU and the United 
Kingdom, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with 
governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain coverage and 
reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-
effectiveness of our product candidate to other available therapies. There can be no assurance that our products will be considered 
cost-effective by third-party payors, that an adequate level of reimbursement will be available, or that the third-party payors’ 
reimbursement policies will not adversely affect our ability to sell our products profitably. If reimbursement of our products is 
unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly 
materially. 

Our employees, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other 

improper activities, including noncompliance with regulatory standards and requirements. 

We are exposed to the risk of employee fraud or other illegal activity by our employees, independent contractors, consultants, 
commercial partners and vendors. Misconduct by these parties could include intentional, reckless and/or negligent conduct that fails 
to: comply with the laws of the FDA and other similar foreign regulatory bodies, provide true, complete and accurate information to 
the FDA and other similar foreign regulatory bodies, comply with manufacturing standards we have established, comply with 
healthcare fraud and abuse laws in the U.S. and similar foreign fraudulent misconduct laws, or report financial information or data 
accurately or to disclose unauthorized activities to us. If we obtain FDA approval of any of our product candidates and begin 
commercializing those products in the U.S., our potential exposure under such laws will increase significantly, and our costs 
associated with compliance with such laws are also likely to increase. These laws may impact, among other things, our current 
activities with principal investigators and research patients, as well as proposed and future sales, marketing and education programs. 
In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the 
healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These 
laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and 
commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also 
involve the improper use of information obtained in the course of patient recruitment for clinical trials. 

We have adopted a Code of Conduct and Ethics, but it is not always possible to identify and deter employee misconduct, and 
the precautions we take to detect and prevent inappropriate conduct may not be effective in controlling unknown or unmanaged risks 
or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with 
such laws or regulations. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve 
substantial costs. It is possible that governmental and enforcement authorities will conclude that our, or our employees’, consultants’, 
collaborators’, contractors’, or vendors’ business practices may not comply with current or future statutes, regulations or case law 
interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we 
are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, 
including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion 
from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished 
profits and future earnings, compliance agreements, withdrawal of product approvals, and curtailment of our operations, among other 
things, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval 
and commercialization of any of our product candidates outside the U.S. will also likely subject us to foreign equivalents of the 
healthcare laws mentioned above, among other foreign laws. 

76 

Risks Related to Our Intellectual Property 

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, or lawsuits accusing our 

products of patent infringement, which could be expensive, time-consuming and unsuccessful. 

Competitors may infringe the patents of our licensors. To counter infringement or unauthorized use, we may be required to file 
infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that 
one or more of our patents is not valid or is unenforceable or may refuse to stop the other party from using the technology at issue on 
the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could 
put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly and could put our patent 
applications at risk of not issuing. Defense of these claims, regardless of their merit, would involve substantial litigation expense and 
would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against 
us, we may be enjoined from manufacturing, use, and marketing our products, or may have to pay substantial damages, including 
treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign 
our infringing products, which may be impossible or require substantial time and monetary expenditure. 

Periodic maintenance fees on any issued patent are due to be paid to the U.S. Patent and Trademark Office, or USPTO, and 
foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies 
require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application 
process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the 
applicable rules, there are situations in which noncompliance 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. Noncompliance events that could result in 
abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within 
prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, our 
competitors might be able to enter the market, which would have a material adverse effect on our business. 

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property 

rights. 

The cost to us of any litigation or other proceeding relating to intellectual property rights, even if resolved in our favor, could be 

substantial. Some of our competitors may be better able to sustain the costs of complex patent litigation because they have 
substantially greater resources. If there is litigation against us, we may not be able to continue our operations. 

Should third parties file patent applications or be issued patents claiming technology also used or claimed by us, we may be 

required to participate in interference proceedings in the USPTO to determine priority of invention. We may be required to participate 
in interference proceedings involving our issued patents and pending applications. We may be required to cease using the technology 
or to license rights from prevailing third parties as a result of an unfavorable outcome in an interference proceeding. A prevailing party 
in that case may not offer us a license on commercially acceptable terms. 

Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court or the 

USPTO. 

If we or one of our licensing partners initiate legal proceedings against a third party to enforce a patent covering one of our 

product candidates, the defendant could counterclaim that the patent covering our product candidate, as applicable, is invalid and/or 
unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity and/or unenforceability are commonplace, 
and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Third parties may also 
raise similar claims before administrative bodies in the U.S. or abroad, even outside the context of litigation. Such mechanisms 
include re-examination, post grant review, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). For 
example, on November 24, 2021 an opposition proceeding was initiated in the European Patent Office against our European Patent 
No. 3601533 B1. This opposition proceeding, or any similar proceedings that may arise in the U.S. or foreign jurisdictions, could 
result in revocation or amendment to our patents in such a way that they no longer cover our product candidates. The outcome 
following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we 
cannot be certain that there is no invalidating prior art, of which we, our patent counsel and the patent examiner were unaware during 
prosecution. If a defendant or third party were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at 
least part, and perhaps all, of the patent protection on our product candidates. Such a loss of patent protection could have a material 
adverse impact on our business. 

77 

If we are unable to protect our proprietary rights, we may not be able to compete effectively or operate profitably. 

Our success is dependent in part on maintaining and enforcing the patents and other proprietary rights that we have licensed and 

may develop, and on our ability to avoid infringing the proprietary rights of others. Certain of our intellectual property rights are 
licensed from another entity, and as such the preparation and prosecution of these patents and patent applications was not performed 
by us or under our control. Furthermore, patent law relating to the scope of claims in the biotechnology field in which we operate is 
still evolving and, consequently, patent positions in our industry may not be as strong as in other more well-established fields. The 
patent positions of biotechnology companies can be highly uncertain and involve complex legal and factual questions for which 
important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in biotechnology patents 
has emerged to date. 

The issuance of a patent is not conclusive as to its validity or enforceability and it is uncertain how much protection, if any, will 

be given to the patents we have licensed from the NIH, Moffitt, or MDACC if any of these parties, or we, attempt to enforce the 
patents and/or if they are challenged in court or in other proceedings, such as oppositions, which may be brought in foreign 
jurisdictions to challenge the validity of a patent. A third party may challenge the validity or enforceability of a patent after its 
issuance by the Patent Office. It is possible that a competitor may successfully challenge our patents or that a challenge will result in 
limiting their coverage. Moreover, the cost of litigation to uphold the validity of patents and to prevent infringement can be 
substantial. If the outcome of litigation is adverse to us, third parties may be able to use our patented invention without payment to us. 
Moreover, it is possible that competitors may infringe our patents or successfully avoid the patented technology through design 
innovation. To stop these activities, we may need to file a lawsuit. These lawsuits are expensive and would consume time and other 
resources, even if we were successful in stopping the violation of our patent rights. In addition, there is a risk that a court would decide 
that our patents are not valid and that we do not have the right to stop the other party from using the inventions. There is also the risk 
that, even if the validity of our patents were upheld, a court would refuse to stop the other party on the grounds that its activities are 
not covered by, that is, do not infringe, our patents. 

Should third parties file patent applications, or be issued patents claiming technology also used or claimed by our licensor(s) or 

by us in any future patent application, we may be required to participate in interference proceedings in the USPTO to determine 
priority of invention for those patents or patent applications that are subject to the first-to-invent law in the U.S., or may be required to 
participate in derivation proceedings in the USPTO for those patents or patent applications that are subject to the first-inventor-to-file 
law in the U.S. We may be required to participate in such interference or derivation proceedings involving our issued patents and 
pending applications. We may be required to cease using the technology or to license rights from prevailing third parties as a result of 
an unfavorable outcome in an interference proceeding or derivation proceeding. A prevailing party in that case may not offer us a 
license on commercially acceptable terms. 

We cannot prevent other companies from licensing most of the same intellectual properties that we have licensed or from 

otherwise duplicating our business model and operations. 

Certain intellectual properties that we are using to develop TIL-based cancer therapy products were licensed to us by the NIH. 

The issued or pending patents that the NIH licensed to us are exclusive, and specific with respect to melanoma, breast, HPV-
associated, bladder and lung cancers. No assurance can be given that the NIH has not previously licensed, or that the NIH hereafter 
will not license to other biotechnology companies some or all of the non-exclusive technologies available to us under the NIH License 
Agreement. In addition, one pending U.S. patent application in the NIH License Agreement is not owned solely by the NIH. No 
assurance can be given that NIH’s co-owner of the certain pending U.S. patent application in the NIH License Agreement has not 
previously licensed, or that the co-owner thereafter will not license, to other biotechnology companies some or all of the technologies 
available to us. Co-ownership of these intellectual properties will create issues with respect to our ability to enforce the intellectual 
property rights in courts, and will create issues with respect to the accountability of one entity with respect to the other. 

Since the NCI, Moffitt, MDACC, and others already use TIL therapy for the treatment of metastatic melanoma and other 

indications, their methods and data are also available to third parties, who may want to enter into our line of business and compete 
against us. Other than the Gen 2 manufacturing process, we currently do not own any exclusive rights on our entire product portfolio 
that could be used to prevent third parties from duplicating our business plan or from otherwise directly competing against us. While 
additional technologies that may be developed under our CRADA may be licensed to us on an exclusive basis, no assurance can be 
given that our existing exclusive rights and will be sufficient to prevent others from competing with us and developing substantially 
similar products. 

78 

The use of our technologies could potentially conflict with the rights of others. 

Our potential competitors or others may have or acquire patent rights that they could enforce against us. If they do so, then we 
may be required to alter our products, pay licensing fees or cease activities. If our products conflict with patent rights of others, third 
parties could bring legal actions against us or our collaborators, licensees, suppliers or customers, claiming damages and seeking to 
enjoin manufacturing, use and marketing of the affected products. If these legal actions are successful, in addition to any potential 
liability for damages (including treble damages and attorneys’ fees for willful infringement), we could be required to obtain a license 
to continue manufacturing, promoting the use or marketing the affected products. We may not prevail in any legal action and a 
required license under the patent may not be available on acceptable terms or at all. 

We have conducted an extensive freedom-to-operate, or FTO, analyses of the patent landscape with respect to our lead product 

candidates. Although we continue to undertake FTO analyses of our manufacturing processes, our lead TIL products, and 
contemplated future processes and products, because patent applications do not publish for 18 months, and because the claims of 
patent applications can change over time, no FTO analysis can be considered exhaustive. Furthermore, patent and other intellectual 
property rights in biotechnology remains an evolving area with many risks and uncertainties. As such, we may not be able to ensure 
that we can market our product candidates without conflict with the rights of others. 

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our 

products. 

As is the case with other cell therapy and biopharmaceutical companies, our success is dependent on intellectual property, 

particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involve both technological and legal 
complexity, and is therefore costly, time-consuming and inherently uncertain. In addition, the U.S. has recently enacted and is 
currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent 
protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing 
uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to 
the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and 
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce 
our existing patents and patents that we might obtain in the future. While we do not believe that any of the patents owned or licensed 
by us will be found invalid based on this decision, we cannot predict how future decisions by the courts, the U.S. Congress or the 
USPTO may impact the value of our patents. 

We have limited foreign intellectual property rights and may not be able to protect our intellectual property rights 

throughout the world. 

We have limited intellectual property rights outside the U.S. Filing, prosecuting and defending patents on product candidates in 
all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the 
U.S. can be less extensive than those in the U.S. In addition, the laws of some foreign countries do not protect intellectual property 
rights to the same extent as federal and state laws in the U.S. Consequently, we may not be able to prevent third parties from 
practicing our inventions in all countries outside the U.S., or from selling or importing products made using our inventions in and into 
the U.S. or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to 
develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but 
enforcement is not as strong as that in the U.S. These products may compete with our products and our patents or other intellectual 
property rights may not be effective or sufficient to prevent them from competing. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign 
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, 
trade secrets and other intellectual property protection, particularly those relating to biopharmaceutical products, which could make it 
difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights 
generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and 
attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent 
applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that 
we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to 
enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the 
intellectual property that we develop or license. 

79 

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed 

confidential information of third parties. 

We have received confidential and proprietary information from third parties and our employees and contractors. In addition, 

we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to 
claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed confidential 
information of these third parties or our employees’ former employers. Litigation may be necessary to defend against or pursue these 
claims. For example, we are currently engaged in litigation involving counterclaims that we have brought relating to theft of certain of 
our trade secrets, breach of confidentiality, and related counterclaims. Even if we are successful in resolving these claims, litigation 
could result in substantial cost and be a distraction to our management and employees. 

Risks Related to Our Securities 

Our officers, directors and principal stockholders own a substantial percentage of our stock and will be able to exert 

significant control over matters subject to stockholder approval. 

Our officers, directors, and principal stockholders currently beneficially own a substantial portion of our outstanding voting 

stock. Therefore, these stockholders have the ability and may continue to have the ability to influence our corporate decision making. 
Given current ownership levels, these stockholders may be able to determine some or all matters requiring stockholder approval. For 
example, these stockholders, acting together, may be able to control or influence elections of directors, amendments to our certificate 
of incorporation or bylaws, or approval of any merger, sale of assets, or other major corporate transaction. This level of control may 
prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may believe are in your best interest 
as one of our stockholders. 

Our stock price may be volatile, and our stockholders’ investment in our stock could decline in value. 

The market price of our common stock is likely to be volatile and could fluctuate widely in response to many factors, including 

but not limited to: 

• 
• 

• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 

volatility and instability in the capital markets due to the COVID-19 pandemic; 
announcements of the results of clinical trials by us, our collaborators, or our competitors, or negative developments with 
respect to similar products, including those being developed by our collaborators; 
developments with respect to patents or proprietary rights; 
announcements of technological innovations by us or our competitors; 
announcements of new products or new contracts by us or our competitors; 
actual or anticipated variations in our operating results due to the level of development expenses and other factors; 
changes in financial estimates by equities research analysts and whether our earnings meet or exceed such estimates; 
conditions and trends in the pharmaceutical, biotechnology and other industries; 
receipt, or lack of receipt, of funding in support of conducing our business; 
regulatory developments within, and outside of, the U.S.; 
litigation or arbitration; 
general volatility in the financial markets; 
general economic, political and market conditions and other factors; and 
the occurrence of any of the risks described in this Annual Report on Form 10-K 

You may experience future dilution as a result of future equity offerings or other equity issuances. 

We may have to raise additional capital in the future. To raise additional capital, we may in the future offer additional shares of 

our common stock or other securities convertible into or exchangeable for our common stock at prices that may be lower than the 
current price per share of our common stock. In addition, investors purchasing shares or other securities in the future could have rights 
superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible 
or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in prior 
offerings. Any such issuance could result in substantial dilution to our existing stockholders. 

80 

Future sales of our common stock in the public market could cause our stock price to fall. 

Our stock price could decline as a result of sales of a large number of shares of our common stock or the perception that these 

sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity 
securities in the future at a time and at a price that we deem appropriate. 

As of December 31, 2021, we had 157,004,742 shares of common stock outstanding. In addition, we had 16,655,260 shares of 

common stock equivalents that would increase the number of common stock outstanding if these instruments were exercised or 
converted to purchase common stock based on vesting requirements of stock options and common stock issuable through purchases of 
employee stock purchase plan, or upon the conversion of preferred stock. The issuance and subsequent sale of the shares underlying 
these common stock equivalents could depress the trading price of our common stock. On June 10, 2019, our certificate of 
incorporation was amended to increase the number of authorized shares of our common stock, par value $0.000041666, from 
150,000,000 shares to 300,000,000 shares, which was approved by our stockholders on that date. 

In addition, in the future, we may issue additional shares of common stock or other equity or debt securities convertible into 

common stock in connection with a financing, acquisition, litigation settlement, employee arrangements or otherwise. For example, in 
June 2020, we issued 19,475,806 shares of common stock in connection with an underwritten public offering, and we may offer 
additional shares under our automatic shelf registration statement in the future. Future issuances may result in substantial dilution to 
our existing stockholders and could cause our stock price to decline. 

If equities or industry analysts do not publish research or reports about our company, or if they issue adverse or misleading 

opinions regarding us or our stock, our stock price and trading volume could decline. 

Although we have research coverage by equities analysts, if coverage is not maintained, the market price for our stock may be 

adversely affected. Our stock price also may decline if any analyst who covers us issues an adverse or erroneous opinion regarding us, 
our business model, our intellectual property or our stock performance, or if our clinical trials and operating results fail to meet 
analysts’ expectations. If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility 
in the financial markets, which could cause our stock price or trading volume to decline and possibly adversely affect our ability to 
engage in future financings. 

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report 

our financial results. As a result, we could become subject to sanctions or investigations by regulatory authorities and/or 
stockholder litigation, which could harm our business and have an adverse effect on our stock price. 

As a public reporting company, we are subject to various regulatory requirements, including the Sarbanes-Oxley Act of 2002, 

which requires our management to assess and report on our internal controls over financial reporting. Nevertheless, in future years, our 
testing, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls 
that we would be required to remediate in a timely manner to be able to comply with the requirements of Section 404 of the Sarbanes-
Oxley Act each year. If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act each year, we 
could be subject to sanctions or investigations by the SEC, Nasdaq or other regulatory authorities which would require additional 
financial and management resources and could adversely affect the market price of our common stock. In addition, material 
weaknesses in our internal controls could result in a loss of investor confidence in our financial reports. 

We are, and in the future may be, subject to federal or state securities or related legal actions that could adversely affect our 

results of operations and our business. 

Federal and state securities and related legal actions may result in substantial costs and divert our management’s attention from 

other business concerns, which could seriously harm our business or affect our reputation. We may not be successful in defending 
future claims and cannot provide assurance that insurance proceeds will be sufficient to cover any costs or liability under such claims. 

For example, on December 11, 2020, a purported stockholder derivative complaint was filed by plaintiff Leo Shumacher 

against us, as nominal defendant, and our current directors, as defendants, in the Court of Chancery in the State of Delaware. The 
complaint alleges breach of fiduciary duty and a claim for unjust enrichment in connection with alleged excessive compensation of 
certain of our non-executive directors and seeks unspecified damages on behalf of our company. While we intend to vigorously defend 
against the foregoing complaint, it is not possible to estimate the amount or range of possible loss that might result from these matters. 

81 

 
Our Board of Directors could issue one or more additional series of preferred stock without stockholder approval with the 

effect of diluting existing stockholders and impairing their voting and other rights. 

Our certificate of incorporation, as amended, authorizes the issuance of up to 50,000,000 shares of “blank check” preferred 
stock (of which only 17,000 shares were issued as Series A Convertible Preferred Stock and 11,500,000 shares were issued as Series B 
Convertible Preferred Stock) with designations, rights and preferences as may be determined from time to time by our Board of 
Directors. Our Board of Directors is empowered, without stockholder approval, to issue one or more series of preferred stock with 
dividend, liquidation, conversion, voting or other rights which could dilute the interest of, or impair the voting power of, our common 
stockholders. The issuance of a series of preferred stock could be used as a method of discouraging, delaying or preventing a change 
in control. For example, it would be possible for our Board of Directors to issue preferred stock with voting or other rights or 
preferences that could impede the success of any attempt to effect a change in control of our company. 

We do not anticipate paying cash dividends for the foreseeable future, and therefore investors should not buy our stock if 

they wish to receive cash dividends. 

We have never declared or paid any cash dividends or distributions on our common stock. We currently intend to retain our 

future earnings to support operations and to finance expansion and, therefore, we do not anticipate paying any cash dividends on our 
common stock in the foreseeable future. 

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our 
stockholders to change our management and hinder efforts to acquire a controlling interest in us, and the market price of our 
common stock may be lower as a result. 

There are provisions in our certificate of incorporation, as amended, and amended and restated bylaws that may make it 
difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change in control was considered 
favorable by you and other stockholders. For example, our Board of Directors has the authority to issue up to 38,483,000 additional 
shares of preferred stock and to fix the price, rights, preferences, privileges, and restrictions of the preferred stock without any further 
vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change in control transaction. As 
a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An 
issuance of shares of preferred stock may result in the loss of voting control to other stockholders. 

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which 

regulates corporate acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with 
particular stockholders of those companies. These provisions could discourage potential acquisition proposals and could delay or 
prevent a change in control transaction. They could also have the effect of discouraging others from making tender offers for our 
common stock, including transactions that may be in your best interests. These provisions may also prevent changes in our 
management or limit the price that investors are willing to pay for our stock. 

Our certificate of incorporation, as amended, designates the Court of Chancery of the State of Delaware as the sole and 

exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our 
stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. 

Our certificate of incorporation, as amended, provides that, subject to limited exceptions, the Court of Chancery of the State of 

Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding 
brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees 
or agents to us or our stockholders, creditors or other constituents (3) any action asserting a claim against us arising pursuant to any 
provision of the Delaware General Corporation Law, our certificate of incorporation, as amended, or our amended bylaws, or (4) any 
other action asserting a claim against us that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise 
acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions of our 
certificate of incorporation described above. This choice of forum provision may limit a stockholder’s ability to bring a claim in a 
judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such 
lawsuits against us and our directors, officers, and employees. Further, this choice of forum provision does not preclude or contract the 
scope of exclusive federal or concurrent jurisdiction for any actions brought under the Securities Act or the Exchange Act. Section 27 
of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the 
Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to 
enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. 

82 

In addition, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce 
any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, the exclusive forum provision 
will not apply to suits brought to enforce any duty or liability created by the Securities Act or any other claim for which the federal 
and state courts have concurrent jurisdiction. Accordingly, our exclusive forum provision will not relieve us of our duties to comply 
with the federal securities laws and the rules and regulations thereunder, and our stockholders will not be deemed to have waived our 
compliance with these laws, rules and regulations. 

If a court were to find these provisions of our certificate of incorporation, as amended inapplicable to, or unenforceable in 
respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such 
matters in other jurisdictions, which could adversely affect our business, results of operations and financial condition. Even if we are 
successful in defending against these claims, litigation could result in substantial costs and be a distraction to management and other 
employees. 

Provisions in our amended and restated bylaws could limit our stockholders’ ability to obtain a favorable judicial forum for 

disputes with us or our directors, officers or employees. 

Our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the federal 

district courts of the U.S. shall be the exclusive forum for the resolution of any complaint asserting a cause of action under the 
Securities Act. This provision limits the ability of our shareholders to bring claims under the Securities Act in any court other than the 
U.S. federal courts, which ultimately may disadvantage our shareholders or be cost prohibitive. Notwithstanding the foregoing, there 
is uncertainty as to whether a court (other than state courts in the State of Delaware, which have recently upheld the validity of such a 
provision) would enforce such a provision and whether investors can waive compliance with the federal securities laws and the rules 
and regulations thereunder. Furthermore, the exclusive forum provision only applies to claims brought under the Securities Act, and 
does not apply to actions arising under the Exchange Act, which is already subject to federal courts as the exclusive forum. 

If a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one 
or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other 
jurisdictions, which could adversely affect our business, results of operations and financial condition. Even if we are successful in 
defending against these claims, litigation could result in substantial costs and be a distraction to management and other employees.

Item 2.          Properties 

San Carlos New Headquarters Lease 

On February 8, 2021, we entered into a lease agreement with ARE-San Francisco No. 63, LLC, or the New Headquarters 

Lease, for laboratories and offices to be constructed in Suite 400 of an existing building located at 825 Industrial Road, San Carlos, 
California, or the Building, commonly known as The District. Under the New Headquarters Lease, we will lease approximately 
49,918 rentable square feet of space in the Building, or the Headquarters Premises. The New Headquarters Lease is for a term of 120 
months, commencing upon the first day of the first full month, or the Rent Commencement Date after the earlier to occur of (i) the 
date that is 12 months and one day after the execution date of the New Headquarters Lease, or the Commencement Date, which is 
February 9, 2022, or (ii) the date that the Tenant Improvements are substantially completed, which was completed in January 2022; 
provided, however, that the Rent Commencement Date shall be delayed one day for each day after the Commencement Date that (a) to 
the extent that, after the Commencement Date, any governmental authority having jurisdiction, as a result of the COVID-19 outbreak 
in the United States, declares or implements any order or mandate that restricts construction activities in San Mateo County, California 
(any such order or mandate, a Government Mandate), to the extent that such Government Mandate precludes the construction of 
tenant improvements, or (b) a landlord delay occurs. The New Headquarters Lease includes an option to extend the term of the lease 
for 60 months, exercisable under certain conditions and at a market rate as described in the New Headquarters Lease. 

Commencing 210 days after the Rent Commencement Date as the result of a rent abatement, our monthly base rent under the 

New Headquarters Lease will be approximately $0.3 million, subject to an annual increase of 3%. Beginning in 2022, we will also be 
responsible for paying operating expenses. 

83 

 
 
The 120-month term of the New Headquarters Lease commenced in January 2022.  Minimum rental payments under the New 

Headquarters Lease total $36.5 million for the entire term of the lease, which does not include rental payments related to our one-time 
option to extend for an additional five years. In addition, the lessor has provided for a tenant improvement allowance of up to $8.2 
million, which is expected to be fully utilized. 

San Carlos Former Headquarters Lease 

Since August 2016, we have leased 8,733 square feet of space for its corporate headquarters, or the Suite 150 Lease, in San 
Carlos, California. The term of the Suite 150 Lease was 54 months beginning on the commencement date. Monthly lease payments 
were approximately $38,000. 

On October 19, 2018, we entered into an agreement, or the Lease, to lease 12,322 square feet of office space located adjacent to 

our corporate headquarters in San Carlos, California. Monthly lease payments were approximately $59,000, subject to an annual 
increase of 3%. 

On June 19, 2019, we entered into a first amendment, or the Amended Lease, to the Lease, for additional space at our corporate 
headquarters in San Carlos, California. Under the Amended Lease, we leased an additional 8,110 square feet, or the Expansion Space, 
for a total of approximately 20,432 square feet of space. Monthly lease payments were approximately $39,000 for the first year, and 
$40,000 for the second year. 

On February 8, 2021, we entered into two amendments, the Suite 100 and 125 Second Amendment and the Suite 150 First 
Amendment, to the Amended Lease and the Suite 150 Lease, respectively. Under the Suite 100 and Suite 125 Second Amendment, we 
extended the Amended Lease to December 31, 2021. Our monthly base rent under the Suite 100 and Suite 125 Second Amendment 
will be approximately $103,000. We are also responsible for paying its portion of operating expenses and real estate taxes. We have an 
option to extend the expiration of the Suite 100 and Suite 125 Second Amendment for one month or nine months, at its discretion, by 
providing notice as specified in the Suite 100 and Suite 125 Second Amendment. On September 1, 2021, we entered into an agreement 
to extend the lease term to January 31, 2022 for approximately $0.1 million a month. 

Under the Suite 150 First Amendment, we extended the Suite 150 Lease, which also expired on April 30, 2021, to December 
31, 2021. Our monthly base rent under the Suite 150 First Amendment is approximately $44,000. We are also responsible for paying 
our portion of operating expenses and real estate taxes. We have an option to extend the expiration of the Suite 150 First Amendment 
for one month or nine months, at our discretion, by providing notice as specified in the Suite 150 First Amendment. On September 1, 
2021, we entered into an agreement to extend the lease term to January 31, 2022 for approximately $46,000 a month. As of January 
31, 2022, these leases had expired and we had taken possession of Headquarters Premises under the New Headquarters Lease referred 
to above. 

Commercial Manufacturing Facility Agreement 

On May 28, 2019, we entered into a lease agreement with 300 Rouse Boulevard, LLC, or the Commercial Manufacturing 

Facility Lease, for a build-to-suit commercial manufacturing facility, laboratories, and offices located in Philadelphia, Pennsylvania. 
Under the Commercial Manufacturing Facility Lease, we lease approximately 136,000 rentable square feet of space in a building 
located at 300 Rouse Boulevard, Philadelphia, Pennsylvania known as the Iovance Cell Therapy Center, or iCTC. The construction of 
the iCTC began in July 2019 and in the third quarter of 2021 we completed the commissioning activities as well as certain tenant 
improvements, therefore approximately $62.4 million of assets were placed in service. The Commercial Manufacturing Facility Lease 
includes an option to extend the term of the lease by giving the landlord prior written notice thereof at least 18 months in advance of 
expiration date, exercisable under certain conditions as described in the Commercial Manufacturing Facility Lease, such that the 
overall term, when added to the initial term, shall be 359 months. 

Our monthly base rent under the Commercial Manufacturing Facility Lease is approximately $0.3 million, subject to an annual 

increase of 2% for the first ten years, and an annual increase of the greater of 2% or 75% of the average ten-year consumer price 
index. We will also be responsible for paying operating expenses. 

84 

Tampa Lease 

Our research and development facilities consist of 8,673 square feet in a facility located at the University of South Florida 

Research Park in Tampa, Florida. These facilities are leased under an agreement with a lease term through December 2024 for 
approximately $20,500 a month. In June 2020, we amended the lease agreement to further increase the rentable space to 13,139 square 
feet and extend the lease term to June 5, 2025 for approximately $34,500 a month. On December 22, 2021, we entered into a second 
amendment to lease an additional 2,731 square feet of space through June 5, 2025, co-terminus with the existing leased space. 
Monthly lease payments will be approximately $42,500 per month.  

Philadelphia Office Lease 

On May 2, 2019, we entered into an agreement to lease approximately 1,500 square feet of office space in Philadelphia, 

Pennsylvania until July 1, 2019 for a rate of $2,000 a month, and then approximately 4,500 square feet of office space for the 
remainder of a three-year term at an initial rate of $11,063 per month, subject to annual increases of 2.5%. On September 1, 2021, we 
entered into an agreement to extend the lease term for an additional three years to July 31, 2025 for approximately $11,900 a month, 
effective as of June 1, 2022, subject to annual increases of 2.5%. 

On August 1, 2020, we entered into an agreement to lease approximately 2,965 square feet of a training facility space in 
Plymouth Meeting, Pennsylvania for a twelve-month term at a rate of approximately $6,500 per month. This lease was terminated in 
August 2021, which did not have an effect on any of our employees, who continue to be employed by us. 

New York Lease 

We leased office space in New York, New York beginning in January 2017, such office space having a monthly rental of 
approximately $4,000 during 2019 and 2020.  On January 31, 2021, the lease terminated, and we closed our New York office, which 
did not have an effect on any of our employees, who continue to be employed by us. 

We believe that our existing facilities are adequate to meet our current needs, and that suitable additional alternative spaces will 

be available in the future on commercially reasonable terms.

Dividends 

We have never declared or paid any cash dividends on our common stock or any other securities. We anticipate that we will 
retain all available funds and any future earnings, if any, for use in the operation of our business and do not anticipate paying cash 
dividends in the foreseeable future. Payment of future cash dividends, if any, will be at the discretion of the board of directors after 
considering various factors, including our financial condition, operating results, current and anticipated cash needs. 

Under the terms of our Series A Convertible Preferred Stock, we may not declare, pay or set aside any dividends on shares of 
any class or series of capital stock (other than dividends on shares of common stock payable in shares of common stock) unless the 
holders of our Series A Convertible Preferred Stock first receive, or simultaneously receive, an equal dividend on each outstanding 
share of Series A Convertible Preferred Stock. 

Under the terms of our Series B Convertible Preferred Stock, holders shall be entitled to receive dividends on shares equal (on 
an as-if-converted-to-Common-Stock basis) to and in the same form as dividends (other than dividends in the form of common stock) 
actually paid on shares of our Series A Convertible Preferred Stock, common stock or other junior securities when, as and if such 
dividends (other than dividends in the form of common stock) are paid on shares of our Series A Convertible Preferred Stock, 
common stock or other junior securities. No other dividends shall be paid on shares of Series B Convertible Preferred Stock, and we 
may not pay dividends (other than dividends in the form of common stock) on shares of our Series A Convertible Preferred Stock, 
common stock or other junior securities unless it simultaneously complies with the previous sentence.

Overview 

We are a clinical-stage biopharmaceutical company pioneering a transformational approach to cure cancer by harnessing the 

human immune system’s ability to recognize and destroy diverse cancer cells in each patient. TIL therapy is an autologous, polyclonal 
cell therapy platform technology that was originally developed by the National Cancer Institute, or NCI, which conducted initial 
clinical trials of this therapy in diseases such as metastatic melanoma and cervical cancer. Our mission is to be the global leader in 
innovating, developing and delivering TIL therapies for patients with cancer. We have developed a new, shorter  TIL manufacturing 

87 

 
 
 
 
process known as Gen 2, which yields a cryopreserved TIL product. This centralized, proprietary, and scalable manufacturing method 
is being investigated in multiple indications. Our lead product candidates include lifileucel for metastatic melanoma and metastatic 
cervical cancer, as well as LN-145 for metastatic non-small cell lung cancer, or NSCLC. In addition, we are investigating the 
effectiveness and safety of combinations of TIL therapy with immune checkpoint inhibitors, or ICIs, in metastatic melanoma, cervical 
cancer, NSCLC, and head and neck squamous cell carcinoma, or HNSCC. We are investigating peripheral blood lymphocyte, or PBL, 
therapy for patients with relapsed or refractory chronic lymphocytic leukemia, or CLL, and small lymphocytic lymphoma, or SLL, 
through our sponsored trials. We are developing first-in-class genetically edited TIL products based on the inactivation of genes that 
encode immune checkpoint proteins and other proteins, as well as the insertion of genes that encode immunomodulatory proteins. We 
are also developing an alternative interleukin-2, or IL-2, co-therapy for use with TIL therapies. Finally, we are investigating the 
potential for TIL therapy in other oncology indications and treatment settings through academic collaborations with leading cancer 
research centers. 

Our current product candidate pipeline is summarized in the figure below:  

TIL Monotherapy in Metastatic Solid Tumor Cancers 

We have investigated TIL monotherapy in metastatic melanoma, cervical cancer, NSCLC and HNSCC. We are conducting a 

Phase 2 clinical trial, C-144-01, of our lead TIL product candidate, lifileucel, for the treatment of metastatic melanoma. This 
multicenter pivotal trial enrolled melanoma patients with disease progression following treatment with at least one systemic therapy, 
including a PD-1 inhibitor and, if BRAF mutated, a BRAF inhibitor, or a combination of BRAF and MEK inhibitors. Cohort 4 of the 
C-144-01 clinical trial is a single-arm cohort intended to support the submission of a Biologics License Application, or BLA, to the 
Food and Drug Administration, or the FDA, for lifileucel. Cohorts 2 and 4 of the C-144-01 trial use our Gen 2 manufacturing process. 
We completed and closed enrollment of patients into Cohort 2 of the C-144-01 trial in 2018. Results from Cohort 2 of the C-144-01 
clinical trial were initially reported at the American Society of Clinical Oncology annual meeting, or ASCO, in June 2019 and 
subsequently updated at ASCO in June 2021. In addition, detailed Cohort 2 data was published in the Journal of Clinical Oncology in 
May 2021.  

Pivotal Cohort 4 of the C-144-01 trial was enrolled to evaluate ORR as read out by an Independent Review Committee, or IRC, 

as the primary endpoint based on our interpretation of discussions with the FDA as part of an End of Phase 2, or EOP2, meeting held 
with the FDA in the third quarter of 2018. In October 2018, based on the data provided to the FDA during the EOP2 meeting, we 
announced that lifileucel had received a Regenerative Medicines Advanced Therapy, or RMAT, designation from the FDA. 
Enrollment in Cohort 4 of the C-144-01 trial commenced in March 2019 and patient dosing was completed in January 2020.

Previously, we reported the submission of additional potency assay data to the FDA, and at the same time, we also announced 
that we had reached agreement with the FDA on the minimum duration of follow up for Cohort 4 to support our BLA submission for 
lifileucel in the treatment of metastatic melanoma. In May 2021, we announced that we had received regulatory feedback from the 
FDA regarding our potency assays for lifileucel. Following FDA feedback, we have continued our ongoing work developing and 
validating our potency assays and have engaged in discussions with the FDA during the second half of 2021. Our BLA submission for 
lifileucel in metastatic melanoma is expected to occur during the first half of 2022. In connection with this BLA submission, the IRC 
is expected to independently assess responses for Cohort 4 patients through the data cut date, which must be completed prior to BLA 
submission or disclosure of IRC-read data. 

We are also conducting a Phase 2 clinical trial, C-145-04, which is a multicenter pivotal trial to assess the safety and efficacy of 

our lead product candidate lifileucel for the treatment of patients with recurrent, metastatic, or persistent cervical cancer. In February 
2019, lifileucel received Fast Track designation from the FDA for development in the treatment of cervical cancer with disease 
progression on or after chemotherapy. In March 2019, the protocol for this trial was amended to modify the primary endpoint of ORR 
to be determined by IRC. In May 2019, lifileucel received Breakthrough Therapy Designation, or BTD, from the FDA for 
development in the treatment of cervical cancer. Results from the C-145-04 clinical trial were reported at ASCO in June 2019. In 
November 2019, we amended the C-145-04 trial to collect additional data on early-line patients as well as late-line patients by adding 
additional cohorts, in anticipation of a changing landscape in this indication, including Cohort 2 for patients that had previously 
received chemotherapy and anti-PD-1/anti-PD-L1 therapy. In January 2021, we announced that Cohort 2 of the C-145-04 trial had 
completed enrollment and that data from this cohort may be supportive of registration because of the expected changing landscape of 
care for cervical cancer patients. For example, because of recent regulatory approvals for pembrolizumab, there may be a potential 
shift from chemotherapy in front-line cervical cancer followed by pembrolizumab in second-line cervical cancer. We intend to execute 
our strategy based on dialog and feedback on these cohorts and continue to plan for a potential BLA submission for lifileucel in 
cervical cancer. 

In November 2020, we announced that we had finalized the protocol for our potential registrational clinical trial in NSCLC, 

IOV-LUN-202, to investigate LN-145 in patients with metastatic NSCLC, without driver mutations, who previously received a single 
line of approved systemic therapy of combined checkpoint inhibitor and chemotherapy. The IOV-LUN-202 clinical trial includes three 
cohorts. Cohorts 1 and 3 of the IOV-LUN-202 clinical trial are enrolling patients with a PD-L1 TPS of less than one percent at the 
time they started front-line therapy, and Cohort 2 will enroll patients with a PD-L1 TPS of greater than or equal to one percent at the 
time they started front-line therapy. Cohort 3 will also explore manufacturing TIL extracted from core biopsies using our third-
generation, or Gen 3, manufacturing process. In June 2021, we reported that the first patient was dosed in the IOV-LUN-202 clinical 
trial. We intend to continue to enroll patients in the IOV-LUN-202 clinical trial throughout 2022. We are engaged in regulatory 
discussions with the FDA on IOV-LUN-202 and intend to incorporate FDA feedback to optimize this clinical trial to support further 
registration in NSCLC. 

In June 2021, we reported initial data for LN-145 in Cohort 3B of our IOV-COM-202 clinical trial in metastatic NSCLC. IOV-

COM-202 is a Phase 2, multicenter trial for that is composed of seven cohorts. Cohort 3B of IOV-COM-202 enrolled patients with 
metastatic NSCLC that had progressed on prior ICI therapy, including patients with oncogene-driven tumors who received prior 
tyrosine kinase inhibitor therapy. Patients were treated with LN-145 monotherapy. All patients treated in Cohort 3B of the IOV-COM-
202 trial received prior anti-PD-1/L1 therapy and all six responding patients also received prior chemotherapy. We also provided an 
update on Cohort 3B in November 2021, at the Society for Immunotherapy in Cancer Annual Meeting, or SITC.  

C-145-03 is our Phase 2, multicenter trial to assess the safety and efficacy of our product candidate LN-145 for the treatment of 

patients with metastatic HNSCC. We redesigned our C-145-03 trial to include multiple cohorts, in order to allow for dosing of TIL 
therapies produced by multiple manufacturing methods, including our Gen 2 manufacturing process, our Gen 3 manufacturing 
process, and our PD-1 selected TIL manufacturing process. Our PD-1 selected TIL manufacturing process results in a product that we 
refer to as LN-145-S1. In January 2021, we announced that we are closing the C-145-03 clinical trial after the trial reached its pre-
specified enrollment target. 

TIL Combinations in Earlier Treatment Settings for Solid Tumors 

We are also investigating the potential of our TIL therapies in earlier lines of treatment in combination with pembrolizumab or 
other ICIs in cancer patients who are naïve to anti-PD-1 therapy, including in four cohorts in our IOV-COM-202 study in solid tumors 

89 

 
 
 
 
 
 
 
as well as in one cohort in our C-145-04 clinical study in cervical cancer. In addition to its ongoing enrollment in the U.S., the IOV-
COM-202 trial has also received regulatory approval in Canada and in certain European countries. 

In Cohort 1A of the IOV-COM-202 trial, we are enrolling advanced unresectable or metastatic melanoma patients who are 
naïve to anti-PD-1 therapy. In Cohort 2A of the IOV-COM-202 trial, we are enrolling advanced, recurrent, or metastatic HNSCC 
patients who are naïve to prior immunotherapy including anti-PD-1/anti-PD-L1 therapy. The patients receive LN-145 in combination 
with pembrolizumab. In Cohort 3, which is our C-145-04 cervical cancer study, patients receive TIL plus pembrolizumab. We 
reported results from ongoing Cohort 1A of the IOV-COM-202 trial at ASCO in June 2021, as well as provided updated results in 
November 2021 at SITC. Our oral presentation at SITC in November 2021 also included initial results for TIL therapy plus 
pembrolizumab for patients enrolled in Cohort 3 of our C-145-04 cervical cancer study.  

The Cohort 1A and Cohort 2A results from the IOV-COM-202 study as well as Cohort 3 from the C-145-04 study 

demonstrated that lifileucel or LN-145 can be safely combined with pembrolizumab. The treatment emergent adverse event, or TEAE, 
profile in all Cohorts was consistent with the underlying advanced disease and the known adverse event profiles of pembrolizumab, 
lymphodepletion, and IL-2 regimens. Two additional cohorts, Cohort 3A and 3C in the IOV-COM-202 study, explore LN-145/ICI 
combination therapies in NSCLC patients. Cohort 3A is evaluating LN-145 in combination with pembrolizumab in patients with 
recurrent or metastatic NSCLC who have not received prior immunotherapy, including checkpoint inhibitors. Cohort 3C is 
investigating LN-145 therapy in combination with ipilimumab and nivolumab in patients with recurrent or metastatic NSCLC who 
have previously received one line of approved checkpoint inhibitor monotherapy as the only prior line of systemic therapy. 

In September 2021, we announced that our Iovance Cell Therapy Center, or the iCTC, had successfully manufactured and 

delivered its first clinical batch of LN-145 for the IOV-COM-202 trial, representing our first internally manufactured TIL product.  
We continue to supply the IOV-COM-202 trial, and other ongoing trials, with both internally manufactured and externally 
manufactured TIL products. 

Next-Generation and Genetically Modified Product Candidates 

Our clinical pipeline also includes next generation TIL product candidates and manufacturing processes, as well as a cytokine-

engrafted protein. Our TIL candidate LN-145-S1, in which TIL are selected for PD-1 expression, is being investigated in post-anti-
PD-1 melanoma in Cohort 1B of our IOV-COM-202 basket study as well as in post-anti-PD-1 HNSCC in Cohort 4 of our C-145-03 
trial. 

We are using our Gen 3 manufacturing process in Cohort 1C of the IOV-COM-202 clinical trial in melanoma and in Cohort 3 

of the IOV-LUN-202 clinical trial in NSCLC and have previously used it in the C-145-03 clinical trial in HNSCC.  

In November 2019, we announced that our Investigational New Drug, or IND, application for our PBL therapy, IOV-2001, was 
authorized by the FDA. Our sponsored clinical trial using this therapy, IOV-CLL-01, was cleared to proceed and patient dosing began 
in 2020. IOV-2001 is a non-genetically modified, polyclonal T cell product that is manufactured using a nine-day process starting 
from 50 mL of patient's blood. IOV-CLL-01 is a Phase 1/2 clinical trial evaluating the safety and efficacy of IOV-2001 in patients 
with relapsed or refractory CLL or SLL.  

In January 2020, we announced a research collaboration and exclusive worldwide licensing agreement with Cellectis S.A., or 

Cellectis, a clinical-stage biopharmaceutical company focused on developing immunotherapies based on gene-edited allogeneic 
chimeric antigen receptor modified T cells. The worldwide exclusive license enables us to use certain TALEN® technology 
addressing multiple gene targets to develop TIL that have been genetically modified to create potentially more potent cancer 
therapeutics for use in several cancer indications. We are nearing completion of IND-enabling studies under this agreement and expect 
to initiate our first clinical study in 2022 of a genetically modified TIL product candidate, IOV-4001, in which the gene coding for the 
PD-1 protein is inactivated. Financial terms of the license include development, regulatory and sales milestone payments from us to 
Cellectis, as well as royalty payments based on net sales of TALEN-modified TIL products. In addition to IOV-4001, we are currently 
developing additional targets for genetic modification using the TALEN technology, including double-knock out programs in 
preclinical development. 

We continue to explore additional transient and permanent genetic modifications of TILs. For example, under the amended and 

restated patent license agreement we entered into May 2021 with National Institutes of Health, or NIH, an agency of the U.S. Public 
Health Service within the Department of Health and Human Services, we license a patent family related to cytokine-tethered TILs, 

90 

 
 
 
 
 
 
 
which are intended to potentially expand and activate TILs to achieve better efficacy while avoiding systemic side effects of 
cytokines. We are currently developing cytokine-tethered TIL products in preclinical studies. 

In addition, in January 2020, we obtained a license from Novartis Pharma AG, or Novartis, to develop and commercialize an 
antibody cytokine-engrafted protein, which we refer to as IOV-3001. Under the agreement, we paid an upfront payment to Novartis 
and may pay milestones involved in initiation of patient dosing in various phases of clinical development for IOV-3001 and approval 
of a potential product in the U.S., EU, and Japan. We are currently conducting IND enabling studies of this novel IL-2 analog. 
Novartis is also entitled to low-to-mid single digit percentage royalties from commercial sales of IOV-3001. 

Investigator-Sponsored Trials  

Through our academic collaborators, we are also exploring the potential for TIL therapies in additional indications. As part of 

our collaboration program with The University of Texas M.D. Anderson Cancer Center, or MDACC, two Phase 2 trials were initiated 
in 2018. Both trials are sponsored by MDACC. The first trial, NCT03449108, investigates LN-145 manufactured by us, using our 
manufacturing processes, to treat patients with soft tissue sarcoma, osteosarcoma, platinum resistant ovarian cancer, and thyroid 
cancer. A second trial under the collaboration with MDACC, NCT03610490, was previously active. This trial treated patients with 
platinum resistant ovarian cancer, pancreatic and colorectal cancer with TIL manufactured by MDACC. The data obtained using this 
manufacturing process may not be representative of our data using our Gen 2 manufacturing process. We also collaborate with many 
other academic institutions using our TIL therapies. For example, a trial in collaboration with The Ohio State University, 
NCT05176470, is expected to start recruiting in 2022, and explores the use of lifileucel in high-risk melanoma in the neoadjuvant 
setting. 

Intellectual Property 

We have developed our own patent portfolio based on internal research and development activities. As a result, we now own a 
number of pending patent applications and granted patents in the fields of TIL therapy, MIL therapy, and PBL therapy, TIL, MIL, and 
PBL manufacturing processes, and TIL, MIL, and PBL expansion methods. For example, we currently own more than 35 U.S. patents 
related to TIL therapy, including patents directed to compositions and methods of treatment in a broad range of cancers, such as U.S. 
Patent Nos. 10,130,659;  10,166,257; 10,272,113; 10,363,273; 10,398,734; 10,420,799; 10,463,697; 10,517,894; 10,537,595; 
10,639,330; 10,646,517; 10,653,723; 10,695,372; 10,894,063; 10,905,718; 10,918,666; 10,925,900; 10,933,094; 10,946,044; 
10,946,045; 10,953,046; 10,953,047; 11,007,225; 11,007,226; 11,013,770; 11,026,974; 11,040,070; 11,052,115; 11,052,116; 
11,058,728; 11,083,752; 11,123,371; 11,141,438 11,168,303; 11,168,304; 11,179,419; 11,202,803; 11,202,804; and 11,241,456. More 
than 30 of these patents are related to our Gen 2 TIL manufacturing processes and have terms that we anticipate will extend to January 
2038, not including any patent term extensions or adjustments that may be available. Our owned and licensed intellectual property 
portfolio also includes patent applications relating to TIL, MIL, and PBL therapies; frozen tumor-based TIL technologies; remnant 
TIL and digest TIL compositions, methods and processes; methods of treatment of a broad range of cancers using TIL therapies; 
methods of manufacturing TIL, MIL, and PBL therapies; the use of costimulatory molecules in TIL therapy and manufacturing; stable 
and transient genetically-modified TIL therapies; methods of using ICIs in combination with TIL therapies; TIL selection 
technologies; and methods of treating patient subpopulations. 

Impact of COVID-19 on our Business 

Operations and Liquidity 

The full impact of the novel strain of coronavirus, or COVID-19, pandemic is unknown and rapidly evolving. While the 

potential economic impact brought by and over the duration of the COVID-19 pandemic may be difficult to assess or predict, the 
COVID-19 pandemic has resulted in significant disruption of global financial markets, which could in the future negatively affect our 
liquidity. In addition, a recession or market volatility resulting from the COVID-19 pandemic could affect our business. We have 
taken proactive, aggressive action throughout the COVID-19 pandemic to protect the health and safety of our employees and expect to 
continue to implement these measures until we determine that the COVID-19 pandemic is adequately contained for purposes of our 
business. We may take further actions as government authorities require or recommend or as we determine to be in the best interests 
of our employees. We do not believe that the COVID-19 pandemic had a material impact on our liquidity or results of operations for 
the year ended December 31, 2021. Further, to date, the COVID-19 pandemic has not had significant effects on our clinical trial 
enrollment. Given the nature and type of our short-term investments in U.S. government securities, we do not believe that the COVID-
19 pandemic will have a material impact on our current investment liquidity. 

91 

 
 
 
 
 
Outlook 

Although there is uncertainty related to the anticipated impact of the recent COVID-19 pandemic on our future results, we 

believe our current cash reserves leave us well-positioned to manage our business through this crisis as it continues to unfold. 
However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the 
COVID-19 pandemic are still uncertain. 

The COVID-19 pandemic is ongoing, and its dynamic nature, including uncertainties relating to the ultimate geographic spread 

of the virus, the severity of the disease, the duration of the pandemic, and actions that would be taken by governmental authorities to 
contain the pandemic or to treat its impact, makes it difficult to forecast any effects on our results for the fiscal year ending 
December 31, 2022. 

Despite the economic uncertainty resulting from the COVID-19 pandemic, we intend to continue to focus on the development 

of our product candidates. We continue to monitor the rapidly evolving situation and guidance from international and domestic 
authorities, including federal, state and local public health authorities and may take additional actions based on their 
recommendations. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan. As 
such, given the dynamic nature of this situation, we cannot reasonably estimate the impacts of COVID-19 on our financial condition, 
results of operations or cash flows in the future. 

Components of Operating Results 

Revenues 

We have not yet generated any revenues since our formation, and we currently do not anticipate that we will generate any 
significant revenues from the sale or licensing of our product candidates during the 12 months from the date these financial statements 
are issued. Our ability to generate revenues in the future will depend on our ability to complete the development of our product 
candidates and to obtain regulatory approval for them. 

Operating Expenses 

Research and Development 

Research and development expenses include personnel and facility-related expenses, outside contracted services including 

clinical trial costs, manufacturing and process development costs, research costs and other consulting services. Research and 
development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for 
future research and development activities are deferred and amortized over the period that the goods are delivered, or the related 
services are performed, subject to an assessment of recoverability. 

Clinical development costs are a significant component of research and development expenses. We have a history of 

contracting with third parties that perform various clinical trial activities on our behalf in connection with the ongoing development of 
our product candidates. The financial terms of these contracts are subject to negotiations and may vary from contract to contract and 
may result in uneven payment flow. We accrue and expense costs for clinical trial activities performed by third parties based upon 
estimates of work completed to date of the individual trial in accordance with agreements established with contract research 
organizations and clinical trial sites. The duration, costs and timing of our clinical trials and development of our product candidates 
will depend on a number of factors that include, but are not limited to, the number of patients that enroll in the trial, per patient trial 
costs, number of sites included in the trial, discontinuation rates of patients, duration of patient follow-up, efficacy and safety profile 
of the product candidate, and the length of time required to enroll eligible patients.  

We expect our research and development expenses to continue to increase as we prepare for commercial manufacturing of our 

products and continue to conduct our clinical trials for other indications. However, it is difficult to determine with certainty the 
duration and completion costs of our current or future preclinical programs and clinical trials of our product candidates. 

92 

 
 
  
 
 
 
 
 
 
 
 
General and Administrative 

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, 

for personnel in executive, finance, accounting, legal, investor relations, facilities, business development, marketing, commercial, 
information technology and human resources functions. Other significant costs include facility costs not otherwise included in 
research and development expenses, legal fees relating to corporate matters and intellectual property, insurance, public company 
expenses relating to maintaining compliance with Nasdaq listing rules and SEC requirements, investor relations costs, and fees for 
accounting and consulting services. General and administrative costs are expensed as incurred, and we accrue for services provided by 
third parties related to the above expenses by monitoring the status of services provided and receiving estimates from its service 
providers and adjusting its accruals as actual costs become known. 

We anticipate general and administrative expenses will increase as we continue to prepare for commercialization and support 

an expected growth of the internal general and administrative team.

Results of Operations for the Years Ended December 31, 2021 and 2020 

Research and development activities are central to our business model. Product candidates in later stage 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. As a clinical stage company that is currently engaged in the development of novel cancer 
immunotherapy products, we have not yet generated any revenues from our biotechnology business or otherwise since our formation. 
Our ability to generate revenues in the future will depend on our ability to complete the development of our product candidates and to 
obtain regulatory approval for them. Our major sources of funding to date have been proceeds from various public and private 
offerings of our equity securities (both common stock and preferred stock), option and warrant exercises, and interest income. Since 
2017 our primary source of funds has been from the public sale of our common stock.

Research and development expense for the year ended December 31, 2021 increased by $57.3 million, or 28%, compared to the 

year ended December 31, 2020. The increase was primarily attributable to (i) a $29.2 million increase in payroll and related expenses 
and a $21.1 million increase in stock-based compensation expenses, both driven by increased hiring of research and development 
employees to support our on-going and planned clinical development activities, (ii) a $14.9 million increase in facility and related 
costs associated with the iCTC and the build-out of our new corporate headquarters office, (iii) a $5.1 million increase in clinical trial 
costs driven by continued enrollment in our IOV-COM-202 and IOV-LUN-202 clinical trials and purchases of study drug used in 
these clinical trials, and (iv) a $2.2 million increase in travel and others, including allocated costs associated with the expansion of our 
infrastructure, including information systems, to further support the growth in the organization and operations associated with our 
clinical trials and pre-commercial efforts. These increases were partially offset by a $10.0 million decrease in research alliance costs 
due to a one-time license fee from Novartis to further develop IOV-3001 which was recognized in full in 2020, and a $5.2 million 
decrease in manufacturing costs driven by completion of our pivotal clinical trials.

and a $7.8 million increase in stock-based compensation expenses, both resulting from increases in headcount to support the growth in 
the overall business and related corporate infrastructure (ii) a $4.3 million increase in insurance and intellectual property filing related 
costs, and (iii) a $2.8 million increase in other costs, including professional fees and costs associated with the build-out of our new 
headquarter office and IT infrastructure to support the continued growth in the overall company. These costs were partially offset by a 
$1.2 million decrease in pre-commercial and marketing costs due to reprioritization of corporate initiatives during the year ended

driven by a higher number of full-time research and development employees and outside services, (ii) a $10.0 million increase for the 
license to further develop IOV-3001 obtained from Novartis, (iii) a $8.3 million increase in stock-based compensation expenses, and 
(iv) a $6.6 million increase in clinical trial costs due to an increase in enrollment across all the trials and initiation of new clinical 
trials. Further, a $0.8 million increase in research consumables cost contributed to the increase. These increases were partially offset 
by lower manufacturing costs by $9.1 million due to decreased production runs in 2020 as a result of completion of enrollment in the 
melanoma pivotal program and a $2.3 million decrease in research alliance expenses due to the COVID-19 pandemic’s impact on 
patient enrollment in the clinical trials with our research alliance partners.

General and administrative expense for the year ended December 31, 2020 increased by $19.4 million, or 47%, compared to the 

year ended December 31, 2019. The increase was primarily attributable to (i) a $8.3 million increase in stock-based compensation 
expenses and a $7.1 million increase in payroll and related expenses driven by a higher number of full-time general and administrative 
employees and higher average stock price, (ii) a $2.1 million increase in director’s and officer’s insurance premiums, (iii) a $1.1 
million increase in intellectual property legal costs, and (iv) a $1.1 million in market research activities as we prepare for 
commercialization. These increases were partially offset by a $0.7 million decrease in travel expenses.

Net loss for the year ended December 31, 2020 increased by $62.0 million or 31%, compared to the year ended December 31, 
2019. The increase in our net loss was due to the continued expansion of our research and development activities, increased clinical 
trials, and the overall growth of our corporate infrastructure.  

Liquidity and Capital Resources 

We have incurred losses and generated negative cash flows from operations since inception. Historically, we have funded our 

operations from various public and private offerings of our equity securities (both common stock and preferred stock), from option 
and warrant exercises, and from interest income. Since 2017, our primary source of funds has been from the public sale of our 
common stock. We currently do not anticipate that we will generate any significant revenues from the sale or licensing of any products 
during the 12 months from the date these financial statements are issued. We expect to further increase our research and development 
activities, especially continuing pre-commercial activities and completing the construction of our tenant improvements to the iCTC 
facility and new corporate headquarters office, which will increase the amount of cash we will use during 2022 and beyond. 
Specifically, we expect increased spending on clinical trials, research and development activities, higher payroll expenses as we 
increase our professional and scientific staff and continue our expansion of manufacturing activities including completion of iCTC

facility as well as completing the construction of the tenant improvement to our new corporate headquarters office in San Carlos, 
California.  

We currently anticipate making aggregate capital expenditures between approximately $10.0 million and $11.0 million during 

the next 12 months, which is expected to primarily include equipment to be used for clinical trials, research and manufacturing at 
iCTC, as well as spending associated with the expansion of our manufacturing facilities of offices. 

As of December 31, 2021, we had $602.1 million in cash, cash equivalents, investments, and restricted cash ($78.2 million of 

cash and cash equivalents, $426.2 million in short-term investments, $91.6 million in long-term investments and $6.1 million in 
restricted cash). Based on the funds we have available as of the date of the filing of this Annual Report on Form 10-K, we believe that 
we have sufficient capital to fund our anticipated operating expenses and capital expenditure for at least 12 months from the date of 
filing this report. 

Corporate Capitalization  

As of December 31, 2021, we had outstanding 157,004,742 shares of our $0.000041666 par value common stock, 194 shares of 

our $0.001 par value Series A Convertible Preferred Stock, and 2,842,158 shares of our $0.001 par value Series B Convertible 
Preferred Stock. The outstanding shares of Series A Convertible Preferred Stock are currently convertible into 97,000 shares of our 
common stock, and the outstanding shares of Series B Convertible Preferred Stock are currently convertible into 2,842,158 shares of 
our common stock. The shares of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock do not have voting 
rights or accrue dividends. 

On September 17, 2019, we filed a shelf registration statement with the SEC for the issuance up to an aggregate amount of 

$400 million (the “2019 Shelf Registration Statement”), which was declared effective on September 24, 2019. The 2019 Shelf 
Registration Statement was terminated upon effectiveness of the 2020 Automatic Shelf Registration Statement (as discussed below). 
No shares were sold under the 2019 Shelf Registration Statement prior to its termination. 

On May 27, 2020, we filed an automatic shelf registration statement with the SEC for the issuance of an indeterminate amount 
of Shelf Securities (the “2020 Automatic Shelf Registration Statement”), which was immediately effective upon filing with the SEC. 
Upon filing of the 2020 Automatic Shelf Registration Statement, the 2019 Shelf Registration Statement was terminated. 

On June 2, 2020, we sold 19,475,806 shares of our common stock at a public offering price of $31.00 per share pursuant to the 

2020 Automatic Shelf Registration Statement (the “June 2020 Public Offering”). We received gross proceeds of $603.7 million and 
net proceeds of $567.0 million, after deducting underwriting discounts and offering expenses. Following the public offering, the 2020 
Automatic Shelf Registration Statement remains available for the future issuance of an indeterminate amount of Shelf Securities. 

On February 8, 2021, we entered into an Open Market Sale Agreement (the “Sales Agreement”), with Jefferies LLC 

(“Jefferies”), with respect to an “at the market” offering program, under which we may, from time to time, in our sole discretion, issue 
and sell through Jefferies, acting as sales agent, up to $350.0 million of shares of our common stock. The issuance and sale, if any, of 
shares of our common stock under the Sales Agreement will be made pursuant to a prospectus supplement, dated February 8, 2021, to 
the 2020 Automatic Shelf Registration Statement. During the year ended December 31, 2021, we received $203.2 million in net 
proceeds through the sale of 6,474,099 shares of our common stock. 

In the future, we may periodically offer one or more of these securities in amounts, prices and terms to be announced when and 
if the securities are offered. If any of the securities covered by the 2020 Shelf Registration Statement are offered for sale, a prospectus 
supplement will be prepared and filed with the SEC containing specific information about the terms of such offering at that time.

Net cash used in operating activities represents cash disbursements related to all of our activities other than investing and 

financing activities. Operating cash flow is derived by adjusting our net loss for non-cash items and changes in operating assets and 
liabilities. Net cash used in operating activities for the year ended December 31, 2021 was $227.9 million compared to $205.1 million 
for the same period in 2020. The increase of $22.8 million in cash used in operating activities was primarily due to an increase in net 
loss driven by increased costs in research and development and pre-commercial activities, which was partially offset by an increase in 
non-cash charges of $38.3 million primarily driven by higher stock-based compensation expenses, amortization of premiums on 
investments and operating right-of-use assets associated with our office and manufacturing facility as well as embedded leases, and 
depreciation expenses. In addition, it reflects a reduction in our operating lease liabilities associated with payments on lease 
arrangements, offset by an increase in accruals and accounts payable primarily related to our increased workforce, overall growth in 
the business and operations, and the timing of vendor invoicing and related payments.  

Net cash used in operating activities for the year ended December 31, 2020 was $205.1 million compared to $158.9 million for 
the same period in 2019. The increase of $46.2 million in cash used in operating activities was primarily attributable to an increase in 
net loss and increase in accruals primarily related to our research and development activities, which were partially offset by an 
increase in non-cash charges of $22.8 million, primarily driven by higher-stock-based compensation expenses and amortization of 
premiums on investments.  

Net cash used in operating activities for the year ended December 31, 2019 was $158.9 million compared to $101.2 million for 

the same period in 2018. The increase of $57.7 million in cash used in operating activities was due to an increase in net loss and an 
increase in operating lease payments, which were partially offset by an increase in non-cash charges of $9.0 million, primarily driven 
by higher-stock-based compensation expenses and amortization of right-of-use assets, and an increase in accruals due to the timing of 
vendor invoicing and related payments.  

Investing Activities 

Net cash (used in) / provided by investing activities primarily consists of purchases, maturities of our investments and capital 
expenditures. Net cash provided by investing activities for the year ended December 31, 2021 was $0.1 million compared to net cash 
used in investing activities of $317.9 million. The increase in cash provided by investing activities of $318.0 million was primarily 
due to the timing of maturities and purchases of investments and lower capital expenditures in 2021. 

Net cash used in investing activities for the year ended December 31, 2020 was $317.9 million compared to net cash provided 
by $90.0 million for the same period in 2019. The increase in net cash used in investing activities of $407.9 million was due primarily 
to purchases of investments with the proceeds received from the June 2020 Public Offering and an increase in capital expenditures to 
support the iCTC build-out. 

Net cash provided by investing activities for the year ended December 31, 2019 was $90.0 million compared to net cash used in 

investing activities of $386.3 million for the same period in 2018. The increase in net cash provided in 2019 was due primarily to the 
timing of maturities and purchases of investments.

Financing Activities 

Net cash provided by financing activities for the year ended December 31, 2021 was $239.3 million compared to net cash 
provided of $576.4 million. The net cash provided by financing activities during the year ended December 30, 2021 related to $203.2 
million cash proceeds from our “at the market” offering and $33.5 million of cash receipts from the issuance of common stock upon 
the exercise of stock options. The net cash provided by financing activities during the year ended December 31, 2020 primarily related 
to $567.0 million cash proceeds received in the June 2020 public offering and $9.7 million cash proceeds from issuance of common 
stock upon exercise of stock options in 2021. 

Net cash provided by financing activities for the year ended December 31, 2020 was $576.4 million compared to net cash 

provided of $6.1 million for the same period in 2019. The net cash provided in financing activities during the year ended December 
31, 2020 primarily related to $567.0 million received from the June 2020 Public Offering and $9.7 million cash proceeds received in 
issuing common stock upon exercise of stock options. Net cash provided by financing activities for the year ended December 31, 2019 
related to cash proceeds received in issuing common stock upon exercise of stock options.  

Net cash provided by financing activities for the year ended December 31, 2019 was $6.1 million compared to net cash 
provided of $424.3 million for the same period in 2018. Net cash provided by financing activities for the year ended December 31, 
2019 related to cash proceeds received in issuing common stock upon exercise of stock options. The net cash provided by financing 
activities of $424.3 million for the year ended December 31, 2018 primarily related to $398.8 million of cash proceeds received from 
January and October 2018 public offerings, $15.8 million cash proceeds from exercise of warrants, and $10.0 million cash proceeds 
from issuing common stock upon exercise of stock options.

(1) 

Our operating lease obligations consist of obligations under non-cancellable operating leases for our facilities in San Carlos, CA, 
Philadelphia, PA, and Tampa, FL.  
Excluded from the above are contractual obligations with certain Contract Manufacturing Organizations, or CMO, for the manufacturing 
facilities and minimum fixed commitment fees included in our manufacturing contracts, such as personnel, general support fee, and 
minimum production or material fees. These obligations met the conditions of embedded leases under Topic ASC 842 and were included 
in the Operating lease liabilities in the Consolidated Balance Sheets. However, these contracts are cancellable upon prior notice and as a 
result, are not included in the above table.   

(2)  We acquire assets still in development and enter into research and development arrangements with third parties that often require 

milestone and royalty payments to the third-party contingent upon the occurrence of certain future events linked to the success of the asset 
in development. Milestone payments may be required, contingent upon the successful achievement of an important point in the 
development life-cycle of the pharmaceutical product (e.g., approval of the product for marketing by a regulatory agency). If required by 
the arrangement, we may have to make royalty payments based upon a percentage of the sales of the pharmaceutical product in the event 
that regulatory approval for marketing is obtained. Because of the contingent nature of these milestone payments, they are not included in 
the table of contractual obligations. 
These arrangements may be material individually, and in the event that milestones for multiple products covered by these arrangements 
were reached in the same period, the aggregate charge to expense could be material to the results of operations in any one period. In 
addition, these arrangements often give us the discretion to unilaterally terminate development of the product, which would allow us to 
avoid making the contingent payments. 

(3) 

The contractual obligations table above excludes estimated equipment and construction costs of approximately $10.0 million to $11.0 
million over the next year for the iCTC facility in Philadelphia, PA and our new corporate headquarters’ office in San Carlos, CA.

Off-Balance Sheet Arrangements 

As of December 31, 2021, we did not have, and currently do not have, any off-balance sheet arrangements.  

Critical Accounting Estimates 

Our accounting policies are more fully described in Note 2 of the consolidated financial statements included in this Annual 

Report on Form 10-K. As described in Note 2, the  preparation of our consolidated financial statements requires us to make estimates 
and judgments that affect the reported amounts in the financial statements and related disclosures. On an ongoing basis, we evaluate 
our significant accounting policies and estimates. We base our estimates on historical experience and on various market-specific and 
other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Estimates are assessed 
each period and updated to reflect current information. Actual results may differ from these estimates. We believe that the following 
discussion addresses our most critical accounting policies, which are those that are most important to the portrayal of our financial 
condition and results of operations and require management’s most difficult, subjective and complex judgments. 

Accrued Research and Development Costs 

Research and development costs are expensed as incurred. Clinical development costs compose a significant component of 

research and development costs. We have a history of contracting with third parties, including contract research organizations 
(“CROs”), independent clinical investigators, and contract manufacturing organizations (“CMOs”) that perform various clinical trial 
activities on our behalf in connection with the ongoing development of our product candidates. The financial terms of these contracts 
are subject to negotiations and may vary from contract to contract and may result in uneven payment flow. We accrue and expense 
costs for clinical trial activities performed by third parties based upon estimates of work completed to date for each clinical trial in 
accordance with agreements established with CROs, hospitals, and clinical investigators. Accruals for CROs and CMOs are recorded 
based on estimates of services received and efforts expended pursuant to agreements established with CROs, CMOs and other outside 
service providers. We determine our estimates through discussions with internal clinical stakeholders and outside service providers as 
to the progress or stage of completion of clinical trials or services and the contracted fee to be paid for such services.  

Included in our clinical development costs are investigator costs, which are costs associated with treatments administered at 

clinical sites as required under each clinical study protocol. Our estimates for clinical investigator costs and timing of expense 
recognition will depend on a number of factors that include, but are not limited to, (i) the overall number of patients that enroll in the 
trial at each individual site, (ii) the length of study enrollment period, (iii) discontinuation and completion rates of patients, 
(iv) duration of patient safety follow-ups, (v) the number of sites included in the clinical trial, and (vi) the contracted fee of each 
participating site for patient treatment while on study, which can vary greatly for several reasons including, but not limited to, 
geographic region, medical center or physician costs, and overhead costs. In addition, our estimates for per patient trial costs will vary 
based on a number of factors that include, but are not limited to, the extent of additional treatments that may be administered by 
investigators as a result of patient health status, recoverability of patient costs through insurance carriers of patients, and unanticipated 
cost of injuries incurred as a result of the study treatment. We accrue for estimated expenses resulting from obligations under 
investigator site agreements as the timing of payments does not always timely align with the periods over which the treatments are 
administered by the clinical investigators. These estimates are typically based on contracted amounts, patient visit data, discussions 
with internal clinical stakeholders and outside service providers, and historical look-back analysis of actual payments made to date.  

We make judgements and estimates in determining the accrual balance in each reporting period. In the event advance payments 

are made to a CRO, CMO or other outside service provider, the payments are recorded within prepaid expenses and other current 
assets and subsequently recognized as research and development expense when the associated services have been performed. As 
actual costs become known, we adjust our estimates, liabilities and assets. Inputs used in our determination of estimates discussed 
above may vary from actual, which will result in adjustments to research and development expense in future periods. Changes in these 
estimates that result in material changes to our accruals could materially affect our results of operations. Our historical estimates have 
not been materially different from actual amounts recorded.

Item 7A.         Quantitative and Qualitative Disclosures About Market Risk 

Interest Rate Risk 

Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level 

of U.S. interest rates, particularly because a significant portion of our investments are in interest bearing cash accounts consisting of 
short-term debt securities issued by the U.S. government. The primary objective of our investment activities is to preserve principal. 
We adhere to an investment policy that requires us to limit amounts invested in securities based on credit rating, maturity, industry 
group and investment type and issuer, except for securities issued by the U.S. government. We do not have any derivative financial 
instruments or foreign currency instruments. As of December 31, 2021, we had $579.0 million invested in marketable securities with a 
maturity date of less than two years. As such we believe that we are not exposed to any material market risk. If interest rates had 
varied by 1% in the year ended December 31, 2021, the fair value of our investment portfolio would increase or decrease by 
approximately $2.9 million. 

Inflation Risk 

Inflation has not had a material effect on our business, financial condition or results of operations during the years ended 

December 31, 2021, 2020, or 2019.

Item 9A.        Controls and Procedures 

(a)  Evaluation of Disclosure Controls and Procedures: 

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 

Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and 
Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including 
our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In 
designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter 
how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and in reaching a 
reasonable level of assurance, management is required to apply its judgment in evaluating the cost-benefit relationship of possible 
controls and procedures. 

As of the end of the period covered by this Annual Report on Form 10-K, we carried out an evaluation, under the supervision 

and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the 
effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our Chief Executive 
Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance 
level. 

(b)  Management’s Annual Report on Internal Control Over Financial Reporting: 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 

is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, 
including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal 
control over financial reporting as of December 31, 2021 based on the framework in Internal Control—Integrated Framework 
2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. Based on that evaluation, our 
management concluded that our internal control over financial reporting was effective as of December 31, 2021.

The independent registered public accounting firm, Ernst and Young LLP, has issued an audit report on our internal control 

over financial reporting. The report on the audit of internal control over financial reporting is included in this Annual Report on 
Form 10-K. 

(c)  Changes in Internal Control Over Financial Reporting: 

There has been no change in our internal control over financial reporting during our most recent fiscal quarter that has 

materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of Iovance Biotherapeutics, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheet of Iovance Biotherapeutics, Inc. (the “Company”) as of 
December 31, 2021, the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for the 
year ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our 
opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2021 and the results of its operations and its cash flows for the year then ended, in conformity with U.S. generally 
accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 

(PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal 
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework) and our report dated February 24, 2022 expressed an unqualified opinion thereon. 

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 audit. We are a public accounting firm registered with the 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 audit 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. Our audit 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 audit 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 audit provides a reasonable basis for our opinion. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that 

was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are 
material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication 
of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are 
not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or 
disclosures to which it relates.

Accrued clinical development costs 

Description of the 
Matter 

How We 
Addressed the 
Matter in Our 
Audit 

During 2021, the Company incurred $38.7 million of research and development expenses and 
accrued $18.0 million of clinical development costs as of December 31, 2021. As described in Note 
2 to the Financial Statements, the Company determines accruals for clinical development costs based 
on the various clinical trial activities performed pursuant to contracts with third-party contract 
research organizations (“CROs”), which comprise a significant component of the Company’s 
research and development expenses. Clinical development costs are accrued and expensed based on 
the percentage of work completed in accordance with agreements established with CROs. The timing 
and amount of payments required under each individual arrangement are often different from the 
pattern of costs actually incurred. The Company accrues clinical development costs under its 
contracts with third-party service providers based on the progress or stage of completion of trials or 
services completed by vendors over the life of the individual trial, number of subjects enrolled, and 
number of sites activated.  

Auditing management’s accounting for accrued clinical development costs is especially challenging 
because the evaluation is dependent on a high volume of data exchanged between third-party service 
providers, internal clinical personnel, and the Company’s finance team. Determining accrued 
amounts is based on an evaluation of the unique terms and conditions set in each respective CRO 
agreement. Additionally, due to the duration of clinical trial activities and the timing of invoices 
received from third parties, the determination of the accrual for services incurred requires 
management to ensure they have complete and accurate information from vendors. 

To test accrued clinical development costs, our audit procedures included, among others, testing the 
accuracy and completeness of the inputs used in management’s analysis to determine costs incurred. 
We also inspected terms and conditions for selected CRO contracts and change orders and compared 
these to the cost models management used in tracking the progress of service agreements. We met 
with internal clinical personnel to understand the status of significant clinical activities. We 
evaluated services provided by third parties by understanding the terms and timeline of significant 
projects, evaluated management’s determination of work performed, subjects enrolled, sites activated 
and costs incurred, and obtained external confirmation of contracts and change orders executed by 
the Company for a sample of CROs as well as key terms and conditions of those contracts. Further, 
we inspected selected invoices received from third parties after the balance sheet date and evaluated 
whether services performed prior to the balance sheet date had been properly included in costs 
accrued.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of Iovance Biotherapeutics, Inc. 

Opinion on Internal Control over Financial Reporting 

We have audited Iovance Biotherapeutics, Inc.’s internal control over financial reporting as of December 31, 2021, based on 

criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, Iovance Biotherapeutics, Inc. (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 

(PCAOB), the balance sheet of the Company as of December 31, 2021 the related statements of operations, comprehensive loss, 
stockholders’ equity and cash flows for the year ended December 31, 2021, and the related notes, and our report dated February 24, 
2022 expressed an unqualified opinion thereon.  

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual 
Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control 
over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 

audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects.  

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 

weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable 
basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 

reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that 
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the 
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being 
made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance 
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements. 

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Shareholders and Board of Directors of  
Iovance Biotherapeutics, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheet of Iovance Biotherapeutics, Inc. (the “Company”) as of 
December 31, 2020, the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for 
each of the two years in the period ended December 31, 2020, 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, 2020, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 
2020, in conformity with accounting principles generally accepted in the United States of America. 

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 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 
audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or 
fraud. 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. 

Critical Audit Matters 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that 

was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are 
material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a 
whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or 
on the accounts or disclosures to which it relates. 

Incremental Borrowing Rate (Leases) 

Description of the Matter 

As discussed in Note 10 to the consolidated financial statements, the Company’s reported right-of-use assets, current lease 
liabilities and long-term lease liabilities, utilize discount rates to calculate the estimated present value of future lease payments.  Since 
the Company’s leases do not provide an implicit rate, management utilized a third-party valuation specialist to assist in estimating the 
incremental borrowing rates used in its present value calculation, which required subjectivity. The incremental borrowing rate is the 
rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease 
payments in a similar economic environment.  As of December 31, 2020, the weighted average incremental borrowing rate used to 
determine the operating lease liability is 8.3%. 

F-5 

Auditing management’s assessment of its incremental borrowing rate is highly subjective and judgmental as the Company has 

no outstanding debt nor committed credit facilities, secured or otherwise, that would have comparable collateral or similar terms as 
their underlying leases.  Further, changes in the incremental borrowing rate may have a material impact on the measurement of the 
Company’s right-of-use assets, current lease liabilities and long-term lease liabilities.  Based on the level of management judgment, 
we have determined the incremental borrowing rate to be a critical audit matter.  This required a high degree of auditor judgment and 
an increased extent of effort, including the need to involve our valuation specialists, when performing audit procedures to evaluate the 
reasonableness of management’s estimation of the incremental borrowing rate. 

How We Addressed the Matter in Our Audit 

Our audit procedures included, amongst others: 

•  We obtained an understanding, evaluated the design, and tested the operating effectiveness of management’s controls with 

regards to the methodology, inputs, and assumptions used to determine the incremental borrowing rate, including those over 
management’s review of its third-party specialist valuation report. 

•  We obtained an understanding of the factors considered and assumptions made by management and the valuation specialists 
in developing the estimate of the incremental borrowing rate, the sources of data relevant to these factors and assumptions 
and the procedures used to obtain the data, and the methods used to calculate the estimate. 

•  We reviewed the contractual terms of the lease agreements to ensure the commencement dates, any lease term extensions 
and/or early termination clauses were properly considered in determining the appropriate lease term for calculating the 
incremental borrowing rates. 

•  With the assistance of our valuation specialists, we performed an independent estimate of the incremental borrowing rate and 

compared the results to the Company’s estimate. 

•  We evaluated the reasonableness of the valuation methods and assumptions used by management and the Company’s 
valuation specialist to estimate the incremental borrowing rates for borrowing amounts and terms comparable to their 
outstanding leases by: 

o  Developing an independent estimate of the incremental borrowing rates with the assistance of our valuation 

specialists by utilizing third party data related to comparable company borrowings with comparable payment terms. 

o  Performing a sensitivity analysis on incremental borrowing rates used to determine the impact rate changes could 
have on the present value calculation of the Company’s operating lease right-of-use assets and operating lease 
liabilities.

IOVANCE BIOTHERAPEUTICS, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

NOTE 1. GENERAL ORGANIZATION, BUSINESS AND LIQUIDITY 

General Organization and Business 

Iovance Biotherapeutics, Inc. (the “Company”) is a clinical-stage biopharmaceutical company pioneering a transformational 

approach to cure cancer by harnessing the human  immune system’s ability to recognize and destroy diverse cancer cells in each 
patient. Tumor infiltrating lymphocyte (“TIL”) therapy is an autologous cell therapy platform technology that was originally 
developed by the National Cancer Institute (“NCI”), which conducted initial clinical trials in diseases such as metastatic melanoma 
and cervical cancer, as well as non-small cell lung cancer. The Company’s mission is to be the global leader in innovating, developing 
and delivering TIL therapy for patients with cancer. The Company has developed a new, shorter proprietary TIL manufacturing 
process known as Generation 2 (“Gen 2”), which yields a cryopreserved TIL product. This centralized, proprietary, and scalable 
manufacturing method is being investigated in multiple indications. The Company’s lead product candidates include lifileucel for 
metastatic melanoma and metastatic cervical cancer, as well as LN-145 for metastatic non-small cell lung cancer (“NSCLC”). In 
addition, the Company is investigating the effectiveness and safety of combinations of TIL therapy with immune checkpoint inhibitors 
(“ICI”), in metastatic melanoma, cervical cancer, NSCLC, and head and neck squamous cell carcinoma (“HNSCC”). The Company is 
investigating peripheral blood lymphocyte (“PBL”) therapy for patients with relapsed or refractory chronic lymphocytic leukemia 
(“CLL”) and small lymphocytic lymphoma (“SLL”) through its sponsored trials. The Company is also investigating the potential for 
TIL therapy in other oncology indications through academic collaborations with leading cancer research centers. On June 1, 2017, the 
Company reincorporated from a Nevada corporation to a Delaware corporation. 

Liquidity 

The Company is currently engaged in the development of therapeutics to fight cancer, specifically solid tumors. The Company 

currently does not have any commercial products and has not yet generated any revenues from its business, nor does the Company 
currently anticipate that it will generate any significant revenues from the sale or licensing of any of its product candidates during the 
12 months from the date these financial statements are issued. The Company has incurred a net loss of $342.3 million for the year 
ended December 31, 2021 and used $227.9 million of cash in its operating activities during the year ended December 31, 2021. As of 
December 31, 2021, the Company had $602.1 million in cash, cash equivalents, investments, and restricted cash ($78.2 million of cash 
and cash equivalents, $426.2 million in short-term investments, $91.6 million in long-term investments and $6.1 million in restricted 
cash). 

The Company expects to continue its research and development activities, increase pre-commercial activities and complete the 
construction of the tenant improvements for the Iovance Cell Therapy Center (the “iCTC”) as well as its new corporate headquarters’ 
office in San Carlos, California, all of which are expected to increase the amount of cash used during 2022 and beyond. Specifically, 
the Company expects continued spending on its current and planned clinical trials, continued expansion of manufacturing activities, 
higher payroll expenses as the Company increases its professional and scientific staff and continuation of pre-commercial activities. 
Based on the funds the Company has available as of the date these financial statements are issued, the Company believes that it has 
sufficient capital to fund its anticipated operating expenses and capital expenditures as planned for at least the next twelve months 
from the date these financial statements are issued. 

Concentrations of Risk 

The Company is subject to credit risk from its portfolio of cash, cash equivalents and investments. Under its investment policy, 

the Company limits amounts invested in securities by credit rating, maturity, industry group, investment type and issuer, except for 
securities issued by the U.S. government. The Company does not believe it is exposed to any significant concentrations of credit risk 
from these financial instruments. The goals of its investment policy are safety and preservation of principal, diversification of risk, and 
liquidity of investments sufficient to meet cash flow requirements.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING PRACTICES 

Cash, Cash Equivalents, and Investments 

The Company’s cash and cash equivalents include short-term investments with original maturities of three months or less when 

purchased. The Company's investments are classified as “available-for-sale.” The Company includes these investments in current 
assets and carries them at fair value. Unrealized gains and losses on available-for-sale securities are included in accumulated other 
comprehensive loss or income. Impairment losses related to credit losses (if any) are recorded as an allowance for credit losses with an 
offsetting entry to net loss. No impairment losses related to credit losses were recognized for the years ended December 31, 2021 and 
2020. The cost of debt securities is adjusted for the amortization of premiums and accretion of discounts to maturity. Such 
amortization and accretion are included in Interest income, net, in the Consolidated Statements of Operations. Gains and losses on 
securities sold are recorded based on the specific identification method and are included in Interest income, net, in the Consolidated 
Statements of Operations. The Company has not incurred any realized gains or losses from sales of securities to date. The Company’s 
investment policy limits investments to certain types of instruments such as certificates of deposit, money market instruments, 
obligations issued by the U.S. government and U.S. government agencies as well as corporate debt securities, and places restrictions 
on maturities and concentration by type and issuer, except for securities issued by the U.S. government.  

Restricted Cash 

The Company maintains a required minimum balance, currently $6.1 million in a segregated bank account in connection with 

three letters of credit, one for $5.45 million for the benefit of the landlord for the iCTC used as a security deposit for the lease (See 
Note 10 - Leases), one for $0.1 million for the benefit of a utilities service provider, and one for $0.6 million for the benefit of the 
landlord for the Company’s new headquarters’ lease. The total amount is classified as Restricted Cash on the Consolidated Balance 
Sheets. The first letter of credit originally expired on May 28, 2020, however, it automatically extends for additional one-year periods, 
without written agreement, to May 28 in each succeeding calendar year, through at least 60 days after the lease expiration date. 
Further, on the expiration of the seventh year of the lease, and each anniversary date thereafter, the letter of credit may be decreased 
by $1.0 million with a minimum security deposit of $1.5 million maintained through the end of the lease term. The second letter of 
credit of $0.1 million expired on March 9, 2021, however, it automatically extends, without written agreement, to the expiration date 
of December 1, 2022. The third letter of credit of $0.6 million expires on February 1, 2032, however, it will be automatically 
extended, without written agreement, for one-year periods to February in each succeeding calendar year. As of December 31, 2021 
and 2020, restricted cash consisted of $6.1 million and $5.5 million and these balances have been classified as a non-current asset on 
the Company’s Consolidated Balance Sheets. 

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated 

Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows (in thousands):

Property and Equipment, net 

Property and equipment are stated at cost, net of accumulated depreciation and amortization. The cost of property and 

equipment is depreciated or amortized on the straight-line method over the following estimated useful lives. The depreciation or 
amortization of capitalized construction in progress costs, a component of property and equipment, net, begins once the underlying 
asset is placed into service and is recognized over the estimated useful lives: 

Computer equipment

Office furniture and equipment 
Lab, process, and validation equipment

  Lesser of the remaining economic life of the asset or the lease-term 

Expenditures for maintenance and repairs are charged to operations as incurred while renewals and betterments are capitalized. 

Gains and losses on disposals are included within operating expenses in the Consolidated Statements of Operations. 

Management assesses the carrying value of property and equipment whenever events or changes in circumstances indicate that 

the carrying value may not be recoverable. If there is indication of impairment, management prepares an estimate of future 
undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If these cash flows are less than the 
carrying amount of the asset, an impairment loss is recognized to write down the asset to its estimated fair value. For the years ended 
December 31, 2021, 2020, and 2019, the Company did not recognize any impairments for its property and equipment. 

Loss per Share 

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding 

during the period. Diluted net loss per share is computed by dividing the net loss by the sum of the weighted average number of shares 
of common stock outstanding and the dilutive common stock equivalent shares outstanding during the period. The Company’s 
potentially dilutive common stock equivalent shares, which include incremental common shares issuable upon (i) the exercise of 
outstanding stock options, (ii) purchases though the 2020 Employee Stock Purchase Plan (the “2020 ESPP”), (iii) vesting of restricted 
stock units, and (vi) conversion of preferred stock, are only included in the calculation of diluted net loss per share when their effect is 
dilutive. 

As of December 31, 2021, 2020, and 2019, the following outstanding common stock equivalents have been excluded from the 

calculation of net loss per share because their impact would be anti-dilutive.

The dilutive effect of potentially dilutive securities would be reflected in diluted earnings per common share by application of 

the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company's common stock 
could result in a greater dilutive effect from potentially dilutive securities.

Fair Value Measurements 

Under Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures, fair value is defined as the 

price at which an asset could be exchanged, or a liability transferred in a transaction between knowledgeable, willing parties in the 
principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or 
parameters or derived from such prices or parameters. Where observable prices or parameters are not available, valuation models are 
applied. 

Assets and liabilities recorded at fair value in the Company’s financial statements are categorized based upon the level of 
judgment associated with the inputs used to measure their fair value. Hierarchical levels directly related to the amount of subjectivity 
associated with the inputs to fair valuation of these assets and liabilities, are as follows: 

-  Level 1—These are investments where values are based on unadjusted quoted prices for identical assets in an active market 

that the Company has the ability to access. 

-  Level 2—These are investments where values are based on quoted market prices in markets that are not active or model 

derived valuations in which all significant inputs are observable in active markets 

-  Level 3—These are financial instruments where values are derived from techniques in which one or more significant inputs 

are unobservable. 

The Company’s financial instruments consist of cash, cash equivalents, short and long-term investments, and long-term notes 

payable, all of which are reported at their respective fair value or approximate fair value on its Consolidated Balance Sheets. 

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant 

to the fair value measurement. The Company’s financial instruments consist of Level 1 and Level 2 assets. Where quoted prices are 
available in an active market, securities are classified as Level 1. 

When quoted market prices are not available for a specific security, the Company estimates the fair value by using quoted 
prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant 
inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets. 
Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based 
observable inputs obtained from various third-party data providers, including but not limited to, benchmark yields, interest rate curves, 
reported trades, broker/dealer quotes, and market reference data. Level 2 assets consist of commercial paper and government agency 
securities. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets and inputs 
other than quoted prices that are observable for the asset. 

Use of Estimates 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of 

America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities 
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of  expenses during 
the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions 
include assumptions made in the fair value of equity awards and related stock-based compensation, assumptions used in measuring 
operating right-of-use assets and operating lease liabilities, accounting for potential liabilities, including estimates inherent in accruals 
related to clinical trials, and the realizability of the Company’s deferred tax assets.

Principles of Consolidation 

The accompanying consolidated financial statements include the accounts of Iovance Biotherapeutics, Inc. and its wholly-
owned subsidiaries, Iovance Biotherapeutics Manufacturing LLC, Iovance Biotherapeutics GmbH, and Iovance Biotherapeutics B.V. 
All intercompany accounts and transactions have been eliminated. The U.S. dollar is the functional currency for all the Company's 
consolidated operations. 

Leases 

The Company determines if an arrangement includes a lease at inception. Operating leases are included in its Consolidated 

Balance Sheets as Operating lease right-of-use assets and Operating lease liabilities as of December 31, 2021. Operating lease right-
of-use assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the 
Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized 
at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value 
of lease payments, the Company uses an estimated incremental borrowing rate that is applicable to the Company based on the 
information available at the later of the lease commencement date or the date of adoption of Accounting Standards Update (“ASU”) 
No. 2016-02 and No. 2018-10 (together “Topic 842”). The operating lease right-of-use assets also include any lease payments made 
less lease incentives. The Company’s leases may include options to extend or terminate the lease, which is considered in the lease 
term when it is reasonably certain that the Company will exercise any such options. Lease expense is recognized on a straight-line 
basis over the expected lease term. The Company has elected not to apply the recognition requirements of Topic 842 for short-term 
leases. 

For lease agreements entered into after the adoption of Topic 842 that include lease and non-lease components, such 

components are generally accounted for separately. 

Stock-Based Compensation 

The Company periodically grants stock options to employees as compensation for services rendered. The Company accounts 

for all stock-based payment awards made to employees, including the employee stock purchase plans, in accordance with the 
authoritative guidance provided by the Financial Accounting Standards Board (“FASB”)  where the value of the award is measured on 
the date of grant and recognized over the vesting period. In accordance with ASU No. 2018-07, Compensation-Stock Compensation 
(“Topic 718”), the Company accounts for stock option grants to non-employees in a similar manner as stock option grants to 
employees except for the term used in the grant date fair value, therefore no longer requiring a re-measurement at the then-current fair 
values at each reporting date until the shares underlying the options have vested. The non-employee awards that contain a performance 
condition that affects the quantity or other terms of the award are measured based on the outcome that is probable. 

The fair value of the Company’s common stock option grants is estimated using a Black-Scholes option pricing model, which 
uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the common stock options, and future 
dividends. The stock-based compensation expense is recorded based upon the value derived from the Black-Scholes option pricing 
model. The assumptions used in the Black-Scholes option pricing model could affect compensation expense recorded in future 
periods. 

The Company issues restricted stock units (“RSUs”) and restricted stock awards (“RSAs”) from time to time as part of its 
equity incentive plans. The Company measures the compensation cost with respect to RSUs and RSAs issued to employees based 
upon the estimated fair value of the equity instruments at the date of the grant, which is recognized as an expense over the period 
during which an employee is required to provide services in exchange for the awards. 

The fair value of RSUs and RSAs is based on the closing price of the Company’s common stock on the grant date. 

Accrued Research and Development Costs 

Research and development costs are expensed as incurred. Clinical development costs compose a significant component of 

research and development costs. The Company has a history of contracting with third parties, including contract research 
organizations (“CROs”), independent clinical investigators, and contract manufacturing organizations (“CMOs”) that perform various 
clinical trial activities on the Company’s behalf in connection with the ongoing development of the Company’s product candidates. 

F-16 

IOVANCE BIOTHERAPEUTICS, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

The financial terms of these contracts are subject to negotiations and may vary from contract to contract and may result in uneven 
payment flow. The Company accrues and expenses costs for clinical trial activities performed by third parties based upon estimates of 
work completed to date for each clinical trial in accordance with agreements established with CROs, hospitals, and clinical 
investigators. Accruals for CROs and CMOs are recorded based on estimates of services received and efforts expended pursuant to 
agreements established with CROs, CMOs and other outside service providers. The Company determines its estimates through 
discussions with internal clinical stakeholders and outside service providers as to the progress or stage of completion of clinical trials 
or services and the contracted fee to be paid for such services. 

Included in the Company’s clinical development costs are investigator costs, which are costs associated with treatments 
administered at clinical sites as required under each clinical study protocol. The Company’s estimates for clinical investigator costs 
and timing of expense recognition will depend on a number of factors that include, but are not limited to, (i) the overall number of 
patients that enroll in the trial at each individual site, (ii) the length of study enrollment period, (iii) discontinuation and completion 
rates of patients, (iv) duration of patient safety follow-ups, (v) the number of sites included in the clinical trial, and (vi) the contracted 
fee of each participating site for patient treatment while on study, which can vary greatly for several reasons including, but not limited 
to, geographic region, medical center or physician costs, and overhead costs. In addition, the Company’s estimates for per patient trial 
costs will vary based on a number of factors that include, but are not limited to, the extent of additional treatments that may be 
administered by investigators as a result of patient health status, recoverability of patient costs through insurance carriers of patients, 
and unanticipated cost of injuries incurred as a result of the study treatment. The Company accrues for estimated expenses resulting 
from obligations under investigator site agreements as the timing of payments does not always timely align with the periods over 
which the treatments are administered by the clinical investigators. These estimates are typically based on contracted amounts, patient 
visit data, discussions with internal clinical stakeholders and outside service providers, and historical look-back analysis of actual 
payments made to date.  

The Company makes judgements and estimates in determining the accrual balance in each reporting period.  

In the event advance payments are made to a CRO, CMO or other outside service provider, the payments are recorded within 

prepaid expenses and other current assets in the Consolidated Balance Sheets and subsequently recognized as research and 
development expense in the Consolidated Statements of Operations when the associated services have been performed. As actual costs 
become known, the Company adjusts its estimates, liabilities and assets. Inputs used in the determination of estimates discussed above 
may vary from actual, which will result in adjustments to research and development expense in future periods. Changes in these 
estimates that result in material changes to the Company’s accruals could materially affect its results of operations. The Company’s 
historical estimates have not been materially different from actual amounts recorded. 

General and Administrative Expenses 

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, 
for personnel in executive, finance, accounting, legal, investor relations, facilities, business development, marketing, commercial and 
human resources functions. Other significant costs include facility costs not otherwise included in research and development expenses, 
sublicense royalty expenses, legal fees relating to corporate matters, insurance, public company expenses relating to maintaining 
compliance with Nasdaq listing rules and Securities and Exchange Commission (“SEC”) requirements, investor relations costs, and 
fees for accounting and consulting services. General and administrative costs are expensed as incurred. 

Income Taxes 

The Company accounts for income taxes using the asset and liability method whereby deferred tax assets are recognized for 

deductible temporary differences, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences 
are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a 
valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not 
be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. 

ASC Topic 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial 
statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement 
of a tax position taken or expected to be taken in a tax return. ASC Topic 740 provides guidance on de-recognition, classification,

interest and penalties, accounting in interim periods, disclosure, and transition. The Company will classify as income tax expense any 
interest and penalties. The Company has no material uncertain tax positions for any of the reporting periods presented. 

Concentrations 

The Company is subject to credit risk from its portfolio of cash, cash equivalents and investments. Under its investment policy, 

the Company limits amounts invested in such securities by credit rating, maturity, industry group, investment type and issuer, except 
for securities issued by the U.S. government. The Company does not believe it is exposed to any significant concentrations of credit 
risk from these financial instruments. The Company maintains cash, cash equivalents and investment balances at four financial 
institutions. Management believes that the financial institutions which hold its cash are financially sound and, accordingly, minimal 
credit risk exists. As of December 31, 2021, and 2020, respectively, the Company’s cash balances were in excess of insured limits 
maintained at the financial institutions. 

Segment Reporting 

The Company operates in one segment, focused on developing and commercializing therapies using autologous TIL for the 

treatment of metastatic melanoma and other solid tumor cancers 

Recently Issued and Adopted Accounting Standards 

Income Taxes 

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income 
Taxes, which simplifies accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the 
approach for allocating income tax expense or benefit for the year to continuing operations, discontinued operations, other 
comprehensive income, and other charges or credits recorded directly to stockholders’ equity; the methodology for calculating income 
tax expense or benefit in an interim period; and recognition of deferred tax liabilities outside basis difference. This ASU became 
effective for the Company on January 1, 2021, however, the adoption of this new standard did not have a material impact on its 
condensed consolidated financial statements and related disclosures.

from the Company (including any price or size limits or other customary parameters or conditions the Company may impose).The 
Company will pay Jefferies a commission of up to 3.0% of the gross sales proceeds of any Common Shares sold through Jefferies 
under the Sales Agreement.

Shares pursuant to the Sales Agreement will terminate upon the earlier to occur of (i) the issuance and sale, through Jefferies, of all 
Common Shares subject to the Sales Agreement and (ii) termination of the Sales Agreement in accordance with its terms. 

For the year ended December 31, 2021, the Company received $203.2 million in net proceeds, net of offering costs, through the

On September 22, 2021, the Board adopted the Iovance Biotherapeutics, Inc. 2021 Inducement Plan (the “2021 Inducement 

Plan”). The 2021 Inducement Plan provides for the grant of non-qualified options, common stock, stock appreciation rights, restricted 
stock awards, restricted stock units, other stock-based awards, other cash-based awards, or any combination of the foregoing. The 
2021 Inducement Plan was recommended for approval by the Compensation Committee of the Board (the “Compensation 
Committee”), and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the 
rules and regulations of The Nasdaq Stock Market, LLC (the “Nasdaq Listing Rules”). 

The Board initially reserved 1,000,000 shares of the Company’s common stock for issuance pursuant to equity awards granted 

under the 2021 Inducement Plan, and the 2021 Inducement Plan will be administered by the Compensation Committee. On January

reserved for issuance under the 2021 Inducement Plan from 1,000,000 shares of the Company’s common stock to 1,750,000 shares of 
the Company’s common stock without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. 

In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, equity awards under the 2021 Inducement Plan may only be 

made to an employee if such employee is granted such equity awards in connection with his or her commencement of employment 
with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company 
or such subsidiary.  In addition, awards under the 2021 Inducement Plan may only be made to employees who have not previously 
been an employee or member of the Board (or any parent or subsidiary of the Company) or following a bona fide period of non-
employment of the employee by the Company (or a parent or subsidiary of the Company). As of December 31, 2021, 723,525 shares 
of common stock were available for grant under the Inducement Plan.

common stock on the offering date or the purchase date with a six month look-back feature. The 2020 ESPP purchases are settled with 
common stock from the 2020 ESPP’s previously authorized and available pool of shares.  

The compensation expense related to the 2020 ESPP for the years ended December 31, 2021 and 2020 were $1.2 million and 
$61,000, respectively. During the year ended December 31, 2021, the Company received proceeds of $1.6 million for the issuance of 
94,148 shares under the 2020 ESPP and there was $0.4 million of unrecognized compensation cost associated with the 2020 ESPP, 
which will be recognized over 5.33 months. As of December 31, 2020, no shares were issued under the 2020 ESPP and there was $0.5 
million of unrecognized compensation cost associated with the 2020 ESPP, to be recognized over 6 months.  

Restricted Stock Units 

On June 1, 2016, the Company entered into an RSU agreement with the Company’s former Chief Executive Officer, pursuant 

to which the Company granted the former Chief Executive Officer 550,000 RSUs as an inducement of employment pursuant to the 
exception to The Nasdaq Global Market rules that generally require stockholder approval of equity incentive plans. These RSUs, 
which included certain performance vesting criteria based upon the satisfaction of certain clinical trial milestones were fully vested as 
of June 1, 2020. No RSUs related to this grant were outstanding at either December 31, 2021 or 2020.  

In June 2021, under the terms of the 2018 Plan, the Company granted 1,253,540 RSUs to its executives and employees. The 

awards are time-based, and each award has one of two vesting conditions. For certain RSU awards, 100% of the RSUs will vest on the

-  Expected Term (Years)—The expected term of the stock option grants was calculated based on historical exercises, 

cancellations, and forfeitures of stock options and outstanding option shares 

-  Expected Volatility —The expected volatility is based on the historical volatility for the Company's stock over a period 

equal to the expected terms of the options. 

-  Risk-Free Interest Rate —The risk-free interest rate was based on the market yield currently available on United States 

Treasury securities with maturities approximately equal to the option’s expected term. 

-  Expected Dividend Yield —The Company has never paid dividends and does not expect to pay dividends in the foreseeable 

future. 

-  Forfeiture Rate —The Company recognizes forfeitures as they occur. 

Each of the inputs discussed above is subjective and generally requires significant management judgment. 

NOTE 7. EMPLOYEE BENEFIT PLAN 

The Company maintains a defined contribution plan covering substantially all U.S. employees under Section 401(k) of the

The Company had net operating loss carryforwards (“NOLs”) for federal and state income tax purposes of approximately 

$945.3 million and $149.6 million, respectively, as of December 31, 2021. $142.4 million of federal NOLs will expire beginning in 
2027, while $803.0 million generated after the recently enacted tax reform will have an indefinite life under the Tax Cuts and Jobs Act 
of 2017 (the “Tax Act”). The state NOLs will expire if unused in years 2030 through 2041. 

The Company’s utilization of NOLs is subject to an annual limitation due to ownership changes that have occurred previously 

or that could occur in the future as provided in Section 382 of the Internal Revenue Code (“Section 382”), as well as similar state 
provisions. Section 382 limits the utilization of NOLs when there is a greater than 50% change of ownership as determined under the 
regulations. Since its formation, the Company has raised capital through the issuance of capital stock and various convertible 
instruments which, combined with the purchasing shareholders’ subsequent disposition of these shares, has resulted in multiple 
ownership changes as defined by Section 382, and could result in ownership change in the future upon subsequent disposition. The 
Company’s utilization of NOLs may also be adversely affected by future changes in federal and state tax laws and regulations. 

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or 

all the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon future generation for 
taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. 
Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in 
making this assessment. After consideration of all the information available, management believes that significant uncertainty exists 
with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the years ended

December 31, 2021 and 2020, the change in the valuation allowance was approximately $78.1 million, $60.7 million, and $50.6 
million, respectively. 

The Company evaluated the provisions of ASC 740 related to the accounting for uncertainty in income taxes recognized in an 

enterprise’s financial statements. ASC 740 prescribes a comprehensive model for how a company should recognize, present, and 
disclose uncertain positions that the Company has taken or expects to take in its tax return. For those benefits to be recognized, a tax 
position must be more-likely-than-not to be sustained upon examination by taxing authorities. Differences between tax positions taken 
or expected to be taken in a tax return and the net benefit recognized and measured pursuant to the interpretation are referred to as 
“unrecognized benefits.” A liability is recognized (or amount of net operating loss carry forward or amount of tax refundable is 
reduced) for unrecognized tax benefit because it represents an enterprise’s potential future obligation to the taxing authority for a tax 
position that was not recognized as a result of applying the provisions of ASC 740. 

If applicable, interest costs related to the unrecognized tax benefits are required to be calculated and would be classified as 

income tax expenses in the Consolidated Statements of Operations. Penalties would be recognized as a component of “General and 
Administrative Expenses” in the Consolidated Statements of Operations. 

A reconciliation of the beginning and ending balances of the unrecognized tax benefits during the years ended December 31, 

2021, 2020, and 2019 is as follows (in thousands): 

Unrecognized benefit - beginning of period 
Gross decreases - prior period tax positions 
Gross increase current period tax positions 
Unrecognized benefit - end of period

No interest or penalties on unpaid tax were recorded during the years ended December 31, 2021, 2020, or 2019. The Company 

does not anticipate any significant changes within 12 months of this reporting date of its uncertain tax positions. 

The Company files tax returns in the U.S. federal and state jurisdictions. The U.S. federal and U.S. state taxing authorities may 
choose to audit tax returns for tax years beyond the statute of limitation period due to significant tax attribute carryforwards from prior 
years, making adjustments only to carryforward attributes. The Company is not currently under examination by income tax authorities 
in federal, state or other foreign jurisdictions. 

NOTE 9. LICENSES AND AGREEMENTS 

National Institutes of Health (the “NIH”) and the National Cancer Institute (the “NCI”) 

Cooperative Research and Development Agreement (the “CRADA”) 

In August 2011, the Company signed a five-year CRADA with the NCI to work on the development of adoptive cell 

immunotherapies that are designed to destroy metastatic melanoma cells. 

The CRADA was amended in January 2015, to include four new indications, including  the development of TIL therapy for the 

treatment of patients with bladder, lung, triple-negative breast, and Human Papilloma Virus (“HPV”)-associated cancers. 

The CRADA was further amended in August 2016 to, among other things, (i) extend the term of the CRADA by another five 

years to August 2021, and (ii) modify the focus on the development of unmodified TIL as a stand-alone therapy or in combination. 
The parties have continued the development of improved methods for the generation and selection of TIL with anti-tumor reactivity in 
metastatic melanoma, bladder, lung, breast, and HPV-associated cancers. 

The CRADA was further amended in August 2021 to, among other things, extend the term of the CRADA by another three 

years to August 2024. The research plan in this amendment includes the evaluation in clinical trials of strategies for development of 
more potent TILs, such as selection of CD39/69 double negative cells and the use of certain inhibitors or other reagents in TIL 
expansion cultures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Pursuant to the terms of the CRADA, as amended, the Company is required to make quarterly payments of $0.5 million to the 
NCI for support of research activities. To the extent the Company licenses patent rights relating to a TIL-based product candidate, the 
Company will be responsible for all patent-related expenses and fees, past and future, relating to the TIL-based product candidate. In 
addition, the Company may be required to supply certain test articles, including TIL, grown and processed under cGMP conditions, 
suitable for use in clinical trials. The extended CRADA has a three-year term expiring in August 2024. The Company or the NCI may 
unilaterally terminate the CRADA for any reason or for no reason at any time by providing written notice at least 60 days before the 
desired termination date. The Company recorded costs associated with the CRADA of $2.0 million, $2.0 million, and $2.2 million for 
the years ended December 31, 2021, 2020 and 2019, respectively, as research and development expenses. 

Patent License Agreement Related to the Development and Manufacture of TIL 

The Company entered into an Exclusive Patent License Agreement (the “Patent License Agreement”) with the NIH, an agency 
of the U.S. Public Health Service within the Department of Health and Human Services, in 2011, as amended in 2015. Pursuant to the 
Patent License Agreement, as amended, the NIH granted the Company licenses, including exclusive, co-exclusive, and non-exclusive 
licenses, to certain technologies relating to autologous tumor infiltrating lymphocyte adoptive cell therapy products for the treatment 
of metastatic melanoma, lung, breast, bladder and HPV-positive cancers. 

Effective May 6, 2021, the Company entered into an Amended and Restated Patent License Agreement with NIH (the 
“Amended and Restated Patent License Agreement”), which includes the grant of additional exclusive, worldwide patent rights in the 
Indications to cytokine-tethered TIL technology, and expands the non-exclusive, worldwide field of use to all cancers. The Amended 
and Restated Patent License Agreement requires the Company to pay royalties based on a percentage of net sales in jurisdictions 
where patent rights exist, which percentage can fall into a tier that may be less than one percent to mid-single digits depending upon 
certain events, including the exclusivity of the rights, and the Company expects lower overall royalty payments as a result. The 
Company also agreed to potential milestone payments on the achievement of certain clinical, regulatory, and commercial sales 
milestones for each of the Indications and other direct costs incurred by the NIH pursuant to the Amended and Restated Patent License 
Agreement. The Company anticipates making milestone payments, including a payment in the low-single-digit millions of dollars in 
conjunction with the approval of a Biologics License Application for any of its product candidates covered by the Amended and 
Restated Patent License Agreement. The term of the Amended and Restated Patent License Agreement continues until the expiry of 
the last-to-expire patent rights licensed thereunder, and the agreement contains standard termination provisions. 

Exclusive Patent License Agreement Related to TIL Selection 

On February 10, 2015, the Company entered into an exclusive patent license agreement (the “Exclusive Patent License 
Agreement”) with the NIH under which the Company received an exclusive license to the NIH’s rights to patent-pending technologies 
related to methods for improving adoptive cell therapy through more potent and efficient production of TIL from melanoma tumors by 
selecting for T cell populations that express various inhibitory receptors. Unless terminated sooner, the license shall remain in effect 
until the last licensed patent right expires. Under the Exclusive Patent License Agreement, the Company agreed to pay customary 
royalties based on a percentage of net sales of a licensed product (which percentage is in the mid-single digits), a percentage of 
revenues from sublicensing arrangements, and lump sum benchmark payments upon the successful completion of clinical studies 
involving licensed technologies, the receipt of the first FDA approval or foreign equivalent for a licensed product or process resulting 
from the licensed technologies, the first commercial sale of a licensed product or process in the U.S., and the first commercial sale of a 
licensed product or process in any foreign country. 

H. Lee Moffitt Cancer Center 

Research Collaboration and Clinical Grant Agreements with Moffitt 

In December 2016, the Company entered into a new three-year Sponsored Research Agreement with H. Lee Moffitt Cancer 

Center (“Moffitt”) which expired in December 2019. In June 2020, the Company entered into a new Sponsored Research Agreement 
with Moffitt, with a term that ends either upon completion of the research thereunder or on July 1, 2022, whichever is sooner, and 
under which immaterial payments will be made to Moffitt in connection with the research services thereunder. In December 2016, the 
Company entered into a clinical grant agreement with Moffitt to support an ongoing clinical trial at Moffitt that combines TIL therapy 
with nivolumab for the treatment of patients with metastatic melanoma. In June 2017, the Company entered into a second clinical 
grant agreement with Moffitt to support a new clinical trial at Moffitt that combines TIL therapy with nivolumab for the treatment of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

patients with non-small cell lung cancer, under which the Company obtained a non-exclusive, royalty-free license to any new Moffitt 
inventions made in the performance of the agreement. Under both clinical grant agreements with Moffit, the Company has non-
exclusive rights to clinical data arising from the respective clinical trials. In the years ended December 31, 2021, 2020 and 2019, the 
Company recorded research and development costs of $0.4 million, $0.6 million, and $0.7 million, respectively, in connection with 
the research collaboration and clinical grant agreements with Moffitt. 

Exclusive License Agreements with Moffitt 

The Company entered into a license agreement with Moffitt (the “First Moffitt License”), effective as of June 28, 2014, under 

which the Company received a world-wide license to Moffitt’s rights to patent-pending technologies related to methods for improving 
TIL for adoptive cell therapy using toll-like receptor agonists. Unless earlier terminated, the term of the license extends until the 
earlier of the expiration of the last issued patent related to the licensed technology or 20 years after the effective date of the license 
agreement. 

Pursuant to the First Moffitt License, the Company paid an upfront licensing fee in the amount of $0.1 million. A patent 
issuance fee will also be payable under the First Moffitt License, upon the issuance of the first U.S. patent covering the subject 
technology. In addition, the Company agreed to pay milestone license fees upon completion of specified milestones, customary 
royalties based on a specified percentage of net sales (which percentage is in the low single digits) and sublicensing payments, as 
applicable, and annual minimum royalties beginning with the first sale of products based on the licensed technologies, which 
minimum royalties will be credited against the percentage royalty payments otherwise payable in that year. The Company will also be 
responsible for all costs associated with the preparation, filing, maintenance and prosecution of the patent applications and patents 
covered by the First Moffitt License related to the treatment of any cancers in the U.S., Europe and Japan and in other countries 
designated by the Company in agreement with Moffitt. No expenses were recorded for the First Moffitt License for the year ended 
December 31, 2021, 2020, and 2019. 

The Company entered into a second license agreement with Moffitt effective as of May 7, 2018 (the “Second Moffitt License”), 
under which the Company received a license to Moffitt’s rights to patent-pending technologies related to the use of 4-1BB agonists in 
conjunction with TIL manufacturing processes and therapies. Pursuant to the Second Moffitt License, the Company paid an upfront 
licensing fee in the amount of $0.1 million in 2018. An annual license maintenance fee is also payable commencing on the first 
anniversary of the effective date. In addition, the Company agreed to pay an annual commercial use payment for each indication for 
which a first sale has occurred, which in the aggregate amounts to up to $0.4 million a year. The Company recorded $0.1 million for 
the years ended December 31, 2021, 2020 and 2019 as research and development expenses in connection with this agreement. The 
Company subsequently exercised an option to exclusively license Moffitt’s rights to patent pending technologies related to the use of 
tumor digests in conjunction with TIL manufacturing processes and therapies, and entered into an amended and restated Second 
Moffitt License in October 2021 (the “Amended & Restated Second Moffit License”), to include these rights. Pursuant to the 
Amended & Restated Second Moffitt License, the Company paid an upfront licensing fee in the amount of $0.2 million in 2021. In 
addition, the Company agreed to pay an annual commercial use payment for each indication for which a first sale has occurred for 
products relating to the use of 4-1BB antagonists and for products relating to the use of tumor digests covered by the license. 

The University of Texas M.D. Anderson Cancer Center 

Strategic Alliance Agreement 

On April 17, 2017, the Company entered into a Strategic Alliance Agreement (the “SAA”) with The University of Texas M.D. 

Anderson Cancer Center (“MDACC”) under which the Company and MDACC agreed to conduct clinical and preclinical research 
studies. The Company agreed in the SAA to provide total funding not to exceed approximately $14.2 million for the performance of 
the multi-year studies under the SAA. In return, the Company acquired all rights to inventions resulting from the studies and has been 
granted a non-exclusive, sub-licensable, royalty-free, and perpetual license to specified background intellectual property of MDACC 
reasonably necessary to exploit, including the commercialization thereof. The Company has also been granted certain rights in clinical 
data generated by MDACC outside of the clinical trials to be performed under the SAA. The SAA’s term shall continue in effect until 
the later of the fourth anniversary of the SAA or the completion or termination of the research and receipt by the Company of all 
deliverables due from MDACC thereunder. The Company recorded $0.5 million, $1.1 million and $3.4 million associated with the 
SAA for the year ended December 31, 2021, 2020, and 2019 as research and development expenses, respectively.

IOV-3001 and approval of the product in the U.S., EU and Japan. Novartis is also entitled to low-to-mid single digit percentage 
royalties from commercial sales of the product. The Company recorded costs associated with the license agreement from Novartis of 
$10.0 million as research and development expenses for the year ended December 31, 2020.  

NOTE 10. LEASES 

Operating Leases 

The Company leases corporate office space in California, including 49,918 square feet for its new corporate headquarters’ 

office space in San Carlos, California, manufacturing, research and development lab facilities and office space in Pennsylvania, 
including 136,000 square feet of commercial manufacturing and lab space in Philadelphia, Pennsylvania, and research and 
development lab facilities in Florida. The determination if an arrangement is a lease occurs at inception, and for leases with terms 
greater than 12 months, the Company records a related right-of-use asset and lease liability at the present value of lease payments over 
the term. Many leases include fixed rental escalation clauses, renewal options and/or termination options that are factored into the 
determination of lease payments when appropriate. The Company’s leases do not provide an implicit rate, and thus the Company 
estimated the incremental borrowing rate in calculating the present value of the lease payments.  

The Company’s leases have remaining lease terms of less than one year to approximately 20 years. Some of our leases include 
one or more options to renew with renewal terms that can extend the lease for additional years, or options to terminate the leases, both 
at the Company’s discretion. The Company’s leases may include options to extend or terminate the lease, which is considered in the 
lease term when it is reasonably certain that the Company will exercise any such options. Lease expense for minimum lease payments 
is recognized on a straight-line basis based on the fixed components of a lease arrangement.  

Variable lease cost is determined based on performance or usage in accordance with the contractual agreements, and not based 

on an index or rate. Such costs that are not fixed in nature are recognized as incurred. 

The Company also leases certain furniture and equipment that has a lease term of 12 months or less. Since the lease agreement 

do not include an option to purchase the underlying asset, the Company elected not to apply the recognition requirements of Topic 842 
for short-term leases, however, the lease costs that pertain to the short-term leases are disclosed in the components of lease costs table 
below.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Manufacturing Contracts 

The Company uses contract manufacturing organizations (collectively the “CMOs” and each a “CMO”) to manufacture and 

supply TILs for clinical and commercial purposes. The CMO contractual obligations consist of the use of manufacturing facilities and 
minimum fixed commitment fees, such as personnel, general support fees, and minimum production or material fees. In addition to the 
minimum fixed commitment fees, the CMO contractual obligations include variable costs such as production and material costs in 
excess of the minimum quantity specified in each CMO agreement. During the term of each CMO agreement, the Company has access 
to and control of the use of a dedicated suite in each of the CMOs’ facilities for manufacturing activities. The contracts with CMOs 
generally contain embedded operating leases based on the fact that the suites are used for the Company’s production are implicitly 
identified, are used exclusively by the Company during the contractual term of the arrangements, and the CMOs have no substantive 
contractual rights to substitute the facilities used by the Company. Further, the Company controls the use of the facilities by obtaining 
all of the economic benefits from the use of the facilities and direct the use of the facilities throughout the period of use. The terms of 
the CMO contracts include options to terminate the lease with an advance notice of five to six months. The termination clauses and 
extension clauses are included in the calculation of the lease term for each of the CMOs when it is reasonably certain that it will not 
exercise such options. 

For contracts with multiple deliverables, Topic 842 requires the Company to first identify a lease deliverable and non-lease 

deliverable included in the arrangements, and then allocate the fixed contractual consideration to the lease deliverable(s) and the non-
lease deliverable(s) on a relative standalone selling price basis to determine the amount of operating lease right-of-use assets and 
liabilities. The Company identified the use of a dedicated suite as a single lease deliverable, and related labor services as a single non-
lease deliverable in each of the CMO arrangements. Judgment is required to determine the relative standalone selling price of each 
deliverable as the observable standalone selling prices are not readily available. Therefore, management uses estimates and 
assumptions in determining relative standalone selling price of lease of a suite and labor service using information that includes 
market and other observable inputs to the extent possible. 

The balance sheet classification of the Company’s right-of-use asset and lease liabilities was as follows (in thousands):

NOTE 11. LEGAL PROCEEDINGS 

Derivative Lawsuit. On December 11, 2020, a purported stockholder derivative complaint was filed by plaintiff Leo Shumacher 
against the Company, as nominal defendant, and its current directors, as defendants, in the Court of Chancery in the State of Delaware.  
The complaint alleges breach of fiduciary duty and a claim for unjust enrichment in connection with alleged excessive compensation 
of certain non-executive directors of the Company and seeks unspecified damages on behalf of the Company.  The defendants intend 
to vigorously defend against the foregoing complaints. Based on the early stage of the litigation, it is not possible to estimate the 
amount or range of possible loss that might result from these matters. 

Solomon Capital, LLC. On April 8, 2016, a lawsuit (“the First Solomon Suit”) titled Solomon Capital, LLC, Solomon Capital 
401(K) Trust, Solomon Sharbat and Shelhav Raff v. Lion Biotechnologies, Inc. was filed by Solomon Capital, LLC, Solomon Capital 
401(k) Trust, Solomon Sharbat and Shelhav Raff (“Solomon Plaintiffs”) against the Company in the Supreme Court of the State of 
New York, County of New York (index no. 651881/2016). The Solomon Plaintiffs allege that, between June and November 2012, 
they provided to the Company $0.1 million and that they advanced and paid on behalf of the Company an additional $0.2 million. The 
complaint further alleges that the Company agreed to (i) provide them with promissory notes totaling $0.2 million, plus interest, 
(ii) issue a total of 1,110 shares to the Solomon Plaintiffs (after the 1-for-100 reverse split of the Company’s common stock effected in 
March 2013) (the “Equity Claim”), and (iii) allow the Solomon Plaintiffs to convert the foregoing funds into its securities in the next 
financing of the Company on the same terms offered to other investors, which Solomon Plaintiffs allege, should have given them the 
right to convert their advances and payments into shares of the Company's common stock in the restructuring that took effect in May 
2013. Based on the foregoing, the Solomon Plaintiffs allege causes for breach of contract and unjust enrichment and demand judgment 
against the Company in an unspecified amount exceeding $1.5 million, plus interest. On June 3, 2016, the Company filed an answer 
and counterclaims in the lawsuits. The Company has asserted counterclaims for fraudulent inducement, fraudulent misrepresentation, 
fraudulent concealment, breach of fiduciary duty, and breach of contract, alleging principally that the counterclaim defendants 
misrepresented their qualifications and failed to disclose that Solomon Sharbat was the subject of an investigation by the Financial 
Industry Regulatory Authority (“FINRA”) that resulted in the loss of his FINRA license. In its counterclaims, the Company is seeking 
damages in an amount exceeding $0.5 million and an order rescinding any and all agreements that the Solomon Plaintiffs contend 
entitled them to obtain shares of Company stock. On May 12, 2020, the court granted the Company’s motion for summary judgment 
limiting the Solomon Plaintiffs’ damages for the Equity Claim to $47,420. The Solomon Plaintiffs filed a notice of appeal of this 
summary judgment on June 9, 2020. On July 2, 2020, the court granted the Company’s motion to dismiss the First Solomon Suit for 
want of prosecution. On January 4, 2021, the court granted the Solomon Plaintiffs motion for reconsideration, and reinstituted the 
case. On January 15, 2021, the Company filed a notice of appeal of the court’s grant of the Solomon Plaintiffs motion for 
reconsideration. On May 11, 2021, the Appellate Division upheld the court’s grant of the Solomon Plaintiffs’ motion for 
reconsideration of the dismissal of the First Solomon Suit for want of prosecution.

IOVANCE BIOTHERAPEUTICS, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

On September 27, 2019, the Solomon Plaintiffs filed a new lawsuit (through new legal counsel) (“the Second Solomon Suit”) 

titled Solomon Capital, LLC, Solomon Capital 401(K) Trust, Solomon Sharbat and Shelhav Raff v. Iovance Biotherapeutics, Inc., 
f/k/a/ Lion Biotechnologies Inc. f/k/a/ Genesis Biopharma Inc., and Manish Singh in the Supreme Court of the State of New York, 
County of New York (index no. 655668/2019). In the Second Solomon Suit, the Solomon Plaintiffs allege that they are third party 
beneficiaries of a “finder’s fee agreement” that prior management entered into with a third party unlicensed entity in 2012 in 
connection with seeking financing, that an agreement or understanding existed between the Company and the plaintiffs that the 
plaintiffs would be paid fees and commissions (in cash and stock) if they obtained financing for the Company, and that they directly 
and indirectly introduced investors to the Company who invested in the Company, or were willing to invest in the Company. Finally, 
the Solomon Plaintiffs allege that they were promised a license to use the Company’s technology in Israel. The plaintiffs claim that the 
Company breached the foregoing understandings, promises and agreements and, as a result, they are entitled to certain damages. The 
Solomon Plaintiffs also allege that Manish Singh, the Company’s former Chief Executive Officer, committed fraud and took shares 
belonging to them. On February 18, 2020, the Company filed a removal petition and removed the Second Solomon Suit to the U.S. 
District Court for the Southern District of New York, where the case has been assigned case no. 1:20-cv-1391. On May 22, 2020, the 
Company moved to dismiss the Second Solomon Suit for lack of personal jurisdiction. On March 26, 2021, Court denied the 
Company’s motion to dismiss for lack of personal jurisdiction. The Company filed a response to the complaint in the Second Solomon 
Suit on April 30, 2021. On May 26, 2021, the Company and Singh filed motions for judgment on the pleadings with respect to the 
second and third claims asserted against the Company and all claims asserted against Singh, respectively, in the Second Solomon Suit. 
On January 5, 2022, the Court granted the Company’s motions for judgement on the pleadings, dismissing the second and third claims 
against the Company and dismissing all claims against Singh. 

The Company intends to vigorously defend these complaints and pursue its counterclaims, as applicable. At the current stage of 

the litigation, in both the First Solomon Suit and the Second Solomon Suit, it is not possible to estimate the amount or range of 
possible loss that might result from an adverse judgment or a settlement of these matters. 

The Company may be involved, from time to time, in legal proceedings and claims arising in the ordinary course of its 

business. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. The Company accrues 
amounts, to the extent they can be reasonably estimated, that it believes are adequate to address any liabilities related to legal 
proceedings and other loss contingencies that it believes will result in a probable loss. While there can be no assurances as to the 
ultimate outcome of any legal proceeding or other loss contingency involving the Company, management does not believe any 
pending matter will be resolved in a manner that would have a material adverse effect on its financial position, results of operations or 
cash flows. 

NOTE 12. LONG-TERM NOTE PAYABLE 

On January 26, 2021, the Company entered into a Loan Note and accompanying Economic Stimulus Program Loan Agreement 

with PIDC – Local Development Corporation, a Pennsylvania nonprofit corporation (the “Lender”), pursuant to which the Lender 
agreed to make a loan (the “Job Creation Loan”) to the Company in a principal amount of $1.0 million. The Job Creation Loan will be 
for a term of five years starting on February 18, 2021, the date of the issuance of a final certificate of occupancy for the Company’s 
leased premises in Philadelphia, Pennsylvania. The Job Creation Loan is unsecured, bears no interest, and will be forgiven by the 
Lender in the amount of $2,000 per full-time or “full time equivalent” (defined as two or more part time employees whose working 
hours total at least 35 hours a week) employee with an average salary of at least $80,000 (“FT Employees”), up to a maximum amount 
equal to the amount of the Job Creation Loan, as calculated based on the average number of FT Employees employed at the 
Company’s premises during the period of the 5-year term beginning on the date that is nine months prior to the maturity date and 
ending on the maturity date. If the Job Creation Loan is not forgiven in full by the maturity date, the remaining balance of the loan not 
forgiven will become payable on the maturity date. The Loan Note includes customary events of default. Upon the occurrence of an 
event of default, the Lender will have the right to exercise remedies against the Company, including the right to require immediate 
payment of all amounts due under the Loan Note. 

The Company concluded that it is not reasonably assured that all or a portion of the loan will be forgiven as of December 31, 

2021, and therefore accounted for the Job Creation Loan as debt in accordance with ASC Topic 470, Debt, as opposed to an in-
substance government grant, and classified as a long-term debt in its Condensed Consolidated Balance Sheets as of December 31, 
2021.
