PricewaterhouseCoopers LLP (“PwC”) has been the Group’s auditors beginning in fiscal year 2016. PwC 
operates procedures to safeguard against the possibility of  its objectivity and independence being 
compromised. This includes PwC’s use of  quality review partners, consultation with internal compliance 
teams and carrying out an annual independence procedure. PwC reports to the Audit Committee of  the 
Company’s Board of  Directors (the “Audit Committee") on matters including independence and non-
audit fees on an annual basis. The PwC audit partner changes every five years. The amount charged by 
the external auditors for the provision of  services during the twelve-month period under review is set 
forth  above.  The  Audit  Committee  assesses  PwC’s  performance  and  is  comfortable  that  PwC  has 
operated effectively during the twelve-month period under review. Resolutions to reappoint PwC as the 
Group’s auditors will be put to shareholders at the Company’s 2021 Annual General Meeting (“AGM”).

INDEPENDENT AUDITORS’ REPORT TO THE 
MEMBERS OF ORCHARD THERAPEUTICS PLC

Report on the audit of the group financial statements 
Opinion 
In our opinion, Orchard Therapeutics plc’s group financial statements: 

(cid:129) give a true and fair view of  the state of  the group’s affairs as at 31 December 2020 and of  its 

loss and cash flows for the year then ended; 

(cid:129)

(cid:129)

have been properly prepared in accordance with United States Generally Accepted Accounting 
Principles (US GAAP); and 

have been prepared in accordance with the requirements of  the Companies Act 2006. 

We have audited the financial statements, included within the Annual Report and Financial Statements 
(the “Annual Report”), which comprise: the Consolidated Balance Sheet as at 31 December 2020; 
the Consolidated Statement of  Operations and Comprehensive Loss, the Consolidated Statement of  
Shareholders’ Equity, and the Consolidated Statement of  Cash Flows for the year then ended; and 
the  notes  to  the  financial  statements,  which  include  a  description  of   the  significant  accounting 
policies. 

Basis for opinion 
We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) 
and  applicable  law.  Our  responsibilities  under  ISAs  (UK)  are  further  described  in  the  Auditors’ 
responsibilities for the audit of  the financial statements section of  our report. We believe that the audit 
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Independence 
We remained independent of  the group in accordance with the ethical requirements that are relevant 
to our audit of  the financial statements in the UK, which includes the FRC’s Ethical Standard, as 
applicable to listed entities, and we have fulfilled our other ethical responsibilities in accordance with 
these requirements. 

Our audit approach 
Overview 
Audit scope 
(cid:129) Of  the group’s seven components, we identified three which, in our view, required an audit of  
their complete financial information, either due to their size or their risk characteristics. In addition 
to the full scope audits, specific audit procedures were performed on selected consolidation 
adjustments made in relation to individually significant balances. This, together with additional 
procedures performed at group level, gave us the evidence we needed. 

(cid:129)

For  our  opinion  of   the  group  as  a  whole,  the  components  where  we  performed  audit  work 
accounted for 99.7% of  group assets and 94.3% of  the group loss. 

Key audit matters

Materiality 
(cid:129) Overall materiality: US$8,000,000 (2019: US$8,200,000) based on 5% of  loss before tax. 

(cid:129) Performance materiality: US$6,000,000.

The scope of  our audit 
As  part  of   designing  our  audit,  we  determined  materiality  and  assessed  the  risks  of   material 
misstatement in the financial statements. 

Capability of  the audit in detecting irregularities, including fraud 
Irregularities, including fraud, are instances of  non-compliance with laws and regulations. We design 
procedures in line with our responsibilities, outlined in the Auditors’ responsibilities for the audit of  
the financial statements section, to detect material misstatements in respect of  irregularities, including 
fraud. The extent to which our procedures are capable of  detecting irregularities, including fraud, is 
detailed below. 

Based  on  our  understanding  of   the  group  and  industry,  we  identified  that  the  principal  risks  of  
non-compliance with laws and regulations related to patent protection, data privacy, product safety 
and regulatory compliance, and we considered the extent to which non-compliance might have a 
material effect on the financial statements. We also considered those laws and regulations that have 
a direct impact on the preparation of  the financial statements such as the Companies Act 2006. We 
evaluated management’s incentives and opportunities for fraudulent manipulation of  the financial 
statements (including the risk of  override of  controls), and determined that the principal risks were 
related to misappropriation of  cash and potential management bias in accounting estimates. The 
group engagement team shared this risk assessment with the component auditors so that they could 
include  appropriate  audit  procedures  in  response  to  such  risks  in  their  work.  Audit  procedures 
performed by the group engagement team and/or component auditors included: 

(cid:129) Discussions with management and internal legal counsel including consideration of  known or 

suspected instances of  non-compliance with laws and regulations and fraud. 

(cid:129) Review of  minutes of  meetings with the Board of  Directors. 

(cid:129) Obtaining direct confirmation from the third party contract research organisation (CRO) around 

the clinical trials being performed on behalf  of  the company. 

(cid:129)

Identifying and testing journal entries, in particular any journal entries posted with unusual account 
combinations impacting cash. 

(cid:129) Challenging assumptions made by management in their significant accounting estimates, in 
particular in relation to the research and development tax credit receivable, and balances held 
with CROs. 

There are inherent limitations in the audit procedures described above. We are less likely to become 
aware of  instances of  non-compliance with laws and regulations that are not closely related to events 
and  transactions  reflected  in  the  financial  statements.  Also,  the  risk  of   not  detecting  a  material 
misstatement due to fraud is higher than the risk of  not detecting one resulting from error, as fraud 
may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or 
through collusion. 

Key audit matters 
Key audit matters are those matters that, in the auditors’ professional judgement, were of  most 
significance  in  the  audit  of   the  financial  statements  of   the  current  period  and  include  the  most 
significant assessed risks of  material misstatement (whether or not due to fraud) identified by the 
auditors, including those which had the greatest effect on: the overall audit strategy; the allocation 
of  resources in the audit; and directing the efforts of  the engagement team. These matters, and any 
comments we make on the results of  our procedures thereon, were addressed in the context of  our 
audit of  the financial statements as a whole, and in forming our opinion thereon, and we do not 
provide a separate opinion on these matters. 

This is not a complete list of  all risks identified by our audit. 

The key audit matters below are consistent with last year.

Key audit matter                                                      How our audit addressed the key audit matter 

Orchard Therapeutics (Europe) Limited Research 
& Development Tax Credit Receivable 
The  Company  carries  out 
research  and 
development  activities  and  submits  tax  credit 
claims  under  one  of   two  U.K.  research  and 
development tax relief  programs: either the Small 
and  Medium-sized  Enterprises  research  and 
development  tax  relief   (“SME”)  program  or  the 
Research  and  Development  Expenditure  Credit 
(“RDEC”)  program.  Each  year  management 
evaluates which tax credit program the Company 
is  expected  to  be  eligible  for  and  records  a 
reduction to research and development expense 
for the portion of  the expense that it expects to 
qualify for credit under the program and ultimately 
be realised. This requires management to make 
judgments  regarding  whether  the  nature  of   the 
activities and expenditures will qualify for the tax 
credit  and  ultimately  be  realised  based  on  the 
allowable 
criteria 
established by the U.K. government. For the year 
the  Company 
ended  31  December  2020, 
recorded $21.1 million as a reduction of  research 
and  development  expense  related  to  these 
programs and has a related tax credit receivable 
of  $13.3 million as of  31 December 2020. There is 
therefore a risk that the Company may recognize 
an excessively high tax credit receivable due to 
overestimating the amount of  eligible expenditure, 
and  that  consequently  not  all  of   the  related  tax 
credit receivable is recoverable.

We have performed the following procedures to 
the  key  audit  matter:  Obtained 
address 
management’s  detailed  calculation,  reconciled 
this 
for 
trial  balance  and 
mathematical  accuracy.  Tested  a  sample  of  
expenses  included  in  the  claim,  including  staff  
costs, consumables, and subcontractor expenses 
to underlying supporting documentation. Tested 
the allocation of  a sample of  expenses to specific 
projects, given that this impacts which tax relief  
programme  the  expenses  are  eligible  to  be 
claimed under, and also impacts the EU State Aid 
cap calculation. Confirmed that the correct uplifts 
and tax rates are being applied in the calculation 
using HMRC sources. Engaged with our R&D Tax 
specialists to assess the estimates included within 
the calculation and the basis on which the claim 
has been prepared, to ensure this is prepared in 
compliance with the relevant laws and regulations. 
No exceptions were identified from the procedures 
performed. 

Impact of  Covid-19 
The COVID-19 pandemic, and measures taken by 
governments in order to contain COVID-19 as well 
as to provide support to businesses, continues to 
potentially  have  a  significant  impact  on  the 
operations, liquidity and/or solvency of  the group. 
The  COVID-19  outbreak  continues  to  create 
uncertainty about the long term outlook of  most 
entities as measures taken by governments might 
change, the disease might spread further, and the 
economic crisis may deepen, all of  which could 
have  an  impact  on  the  group.  The  COVID-19 
pandemic has impacted the group operationally 
with  a  change  to  remote  working  for  most 
employees and a temporary halt in clinical trials 
during the lockdown period, although these are 
now  resuming  in  most  territories  with  social 
distancing restrictions in place. This was reflected 
in a decrease in certain trial-related costs during 
2020 but management consistently budgeted for 
these to increase before the end of  the year as the 
group adapted to remote working practices.

6  Orchard Therapeutics plc 

We  considered  the  impact  of   COVID-19  on  the 
group’s control environment and have performed 
walkthroughs of  the controls in place throughout 
the  pandemic  to  understand  how  the  group’s 
controls have been adapted as a result of  remote 
working.  We  have  concluded  that  the  control 
environment has not been significantly impacted 
by  COVID-19  working  practices  given  that  the 
business  and  staff   are  well  equipped  to  work 
remotely  in  an  effective  manner.  We  have  also 
assessed the impact of  COVID-19 on the ability of  
the  group  to  continue  as  a  going  concern  and 
deem there not be a significant impact, given the 
slowdown 
the 
pandemic, and there being sufficient cash in the 
group to provide runway into 2023 as a result of  
the existing cash reserves held, including from the 
fundraise in February 2021 which generated net 
proceeds of  $144m.

How we tailored the audit scope 
We tailored the scope of  our audit to ensure that we performed enough work to be able to give an 
opinion on the financial statements as a whole, taking into account the structure of  the group, the 
accounting processes and controls, and the industry in which it operates. 

The group is structured such that the significant majority of  its business is comprised of  two operating 
entities - Orchard Therapeutics (Europe) Limited and Orchard Therapeutics North America, both of  
which were scoped as significant components. We also performed a full scope audit of  Orchard 
Therapeutics plc, as the ultimate parent company in the group. The consolidated financial statements 
are  a  consolidation  of   seven  components,  comprising  the  group’s  operating  subsidiaries  and 
centralised functions, which are based throughout the UK, US and Europe. In establishing the overall 
approach  to  the  audit  of   the  consolidated  financial  statements,  we  performed  a  group  scoping 
assessment, and instructed PwC US to perform a full scope audit over Orchard Therapeutics North 
America and Orchard Therapeutics plc, along with certain procedures over Orchard Therapeutics 
(Europe) Limited. We have directed, supervised and reviewed the work of  PwC US throughout the 
audit and maintained regular communication via video calls and email, given that international travel 
has been prohibited during the Covid-19 pandemic. 

Materiality 
The scope of  our audit was influenced by our application of  materiality. We set certain quantitative 
thresholds for materiality. These, together with qualitative considerations, helped us to determine the 
scope of  our audit and the nature, timing and extent of  our audit procedures on the individual financial 
statement line items and disclosures and in evaluating the effect of  misstatements, both individually 
and in aggregate on the financial statements as a whole. 

Based on our professional judgement, we determined materiality for the financial statements as a 
whole as follows: 

Overall group materiality

US$8,000,000.00 (2019: US$8,200,000.00). 

How we determined it

5% of  loss before tax. 

Rationale for benchmark applied The group is loss making, as expected given its status as an early 
stage  biotech  with  only  two  very  early  stage  commercialised 
products.  As  such,  loss  before  tax  is  deemed  to  be  the  most 
appropriate benchmark on which to calculate materiality, as this 
is  the  metric  on  which  the  group’s  financial  performance  is 
assessed. 

For each component in the scope of  our group audit, we allocated a materiality that is less than our 
overall group materiality. The range of  materiality allocated across components was $7 million to $7.4 
million. Certain components were audited to a local statutory audit materiality that was also less than 
our overall group materiality. 

We  use  performance  materiality  to  reduce  to  an  appropriately  low  level  the  probability  that  the 
aggregate of  uncorrected and undetected misstatements exceeds overall materiality. Specifically, 
we use performance materiality in determining the scope of  our audit and the nature and extent of  
our testing of  account balances, classes of  transactions and disclosures, for example in determining 
sample  sizes.  Our  performance  materiality  was  75%  of   overall  materiality,  amounting  to 
US$6,000,000.00 for the group financial statements. 

In determining the performance materiality, we considered a number of  factors – the history of  
misstatements,  risk  assessment  and  aggregation  risk  and  the  effectiveness  of   controls  -  and 
concluded that an amount at the upper end of  our normal range was appropriate.

We agreed with those charged with governance that we would report to them misstatements identified 
during our audit above $400,000 (2019: $410,000) as well as misstatements below that amount that, 
in our view, warranted reporting for qualitative reasons. 

Conclusions relating to going concern 
Our evaluation of  the directors’ assessment of  the group’s ability to continue to adopt the going 
concern basis of  accounting included: 

(cid:129) A review of  management’s latest cash flow forecast, in which we have assessed the forecasts for 
reasonableness,  understood  the  planned  cash  outflows/inflows,  considered  management’s 
previous ability to forecast accurately and tested the funds received from the February 2021 
fundraise to supporting documentation. We also note that a significant proportion of  planned 
expenditure remains under management’s control for the foreseeable future, therefore if  cash 
were to run short, management have a number of  options under which discretionary expenditure 
could be reined back. 

Based on the work we have performed, we have not identified any material uncertainties relating to 
events or conditions that, individually or collectively, may cast significant doubt on the group’s ability 
to  continue  as  a  going  concern  for  a  period  of   at  least  twelve  months  from  when  the  financial 
statements are authorised for issue. 

In auditing the financial statements, we have concluded that the directors’ use of  the going concern 
basis of  accounting in the preparation of  the financial statements is appropriate. 

However,  because  not  all  future  events  or  conditions  can  be  predicted,  this  conclusion  is  not  a 
guarantee as to the group’s ability to continue as a going concern. 

Our  responsibilities  and  the  responsibilities  of   the  directors  with  respect  to  going  concern  are 
described in the relevant sections of  this report. 

Reporting on other information  
The other information comprises all of  the information in the Annual Report other than the financial 
statements and our auditors’ report thereon. The directors are responsible for the other information. 
Our opinion on the financial statements does not cover the other information and, accordingly, we do 
not express an audit opinion or, except to the extent otherwise explicitly stated in this report, any form 
of  assurance thereon. 

In  connection  with  our  audit  of   the  financial  statements,  our  responsibility  is  to  read  the  other 
information and, in doing so, consider whether the other information is materially inconsistent with 
the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially 
misstated. If  we identify an apparent material inconsistency or material misstatement, we are required 
to  perform  procedures  to  conclude  whether  there  is  a  material  misstatement  of   the  financial 
statements  or  a  material  misstatement  of   the  other  information.  If,  based  on  the  work  we  have 
performed,  we  conclude  that  there  is  a  material  misstatement  of   this  other  information,  we  are 
required to report that fact. We have nothing to report based on these responsibilities. 

With  respect  to  the  UK  Statutory  Strategic  Report  and  UK  Statutory  Directors’  Report,  we  also 
considered whether the disclosures required by the UK Companies Act 2006 have been included. 

Based on our work undertaken in the course of  the audit, the Companies Act 2006 requires us also 
to report certain opinions and matters as described below.

UK Statutory Strategic Report and UK Statutory Directors’ Report 
In our opinion, based on the work undertaken in the course of  the audit, the information given in the UK 
Statutory Strategic Report and UK Statutory Directors’ Report for the year ended 31 December 2020 
is consistent with the financial statements and has been prepared in accordance with applicable legal 
requirements. 

In light of  the knowledge and understanding of  the group and its environment obtained in the course 
of  the audit, we did not identify any material misstatements in the UK Statutory Strategic Report and 
UK Statutory Directors’ Report. 

Responsibilities for the financial statements and the audit 
Responsibilities of  the directors for the financial statements 
As explained more fully in the Statement of  directors’ responsibilities in respect of  the financial 
statements, the directors are responsible for the preparation of  the financial statements in accordance 
with the applicable framework and for being satisfied that they give a true and fair view. The directors 
are also responsible for such internal control as they determine is necessary to enable the preparation 
of  financial statements that are free from material misstatement, whether due to fraud or error. 

In preparing the financial statements, the directors are responsible for assessing the group’s ability 
to continue as a going concern, disclosing, as applicable, matters related to going concern and 
using the going concern basis of  accounting unless the directors either intend to liquidate the group 
or to cease operations, or have no realistic alternative but to do so. 

Auditors’ responsibilities for the audit of  the financial statements 
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole 
are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report 
that includes our opinion. Reasonable assurance is a high level of  assurance, but is not a guarantee 
that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement 
when it exists. Misstatements can arise from fraud or error and are considered material if, individually 
or in the aggregate, they could reasonably be expected to influence the economic decisions of  users 
taken on the basis of  these financial statements. 

Our audit testing might include testing complete populations of  certain transactions and balances, 
possibly using data auditing techniques. However, it typically involves selecting a limited number of  
items for testing, rather than testing complete populations. We will often seek to target particular items 
for testing based on their size or risk characteristics. In other cases, we will use audit sampling to 
enable us to draw a conclusion about the population from which the sample is selected. 

A further description of  our responsibilities for the audit of  the financial statements is located on the 
FRC’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of  our auditors’ 
report. 

Use of  this report 
This report, including the opinions, has been prepared for and only for the company’s members as 
a body in accordance with Chapter 3 of  Part 16 of  the Companies Act 2006 and for no other purpose. 
We do not, in giving these opinions, accept or assume responsibility for any other purpose or to any 
other person to whom this report is shown or into whose hands it may come save where expressly 
agreed by our prior consent in writing.

Report on the audit of the parent company financial statements 
Opinion 
In our opinion, Orchard Therapeutics plc’s parent company financial statements: 

(cid:129) give a true and fair view of  the state of  the parent company’s affairs as at 31 December 2020 

and of  its loss for the year then ended; 

(cid:129)

have  been  properly  prepared  in  accordance  with  United  Kingdom  Generally  Accepted 
Accounting Practice (United Kingdom Accounting Standards, comprising FRS 102 “The Financial 
Reporting Standard applicable in the UK and Republic of  Ireland”, and applicable law); and 

(cid:129)

have been prepared in accordance with the requirements of  the Companies Act 2006. 

We have audited the financial statements, included within the Annual Report and Financial Statements 
(the “Annual Report”), which comprise: the Parent Company Balance Sheet as at 31 December 2020; 
the Parent Company Statement of  Changes in Equity for the year then ended; and the notes to the 
financial statements, which include a description of  the significant accounting policies. 

Basis for opinion 
We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) 
and  applicable  law.  Our  responsibilities  under  ISAs  (UK)  are  further  described  in  the  Auditors’ 
responsibilities for the audit of  the financial statements section of  our report. We believe that the audit 
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Independence 
We remained independent of  the parent company in accordance with the ethical requirements that 
are relevant to our audit of  the financial statements in the UK, which includes the FRC’s Ethical 
Standard, as applicable to listed entities, and we have fulfilled our other ethical responsibilities in 
accordance with these requirements.

INDEPENDENT AUDITORS’ REPORT TO THE

Capability of  the audit in detecting irregularities, including fraud 
Irregularities, including fraud, are instances of  non-compliance with laws and regulations. We design 
procedures in line with our responsibilities, outlined in the Auditors’ responsibilities for the audit of  
the financial statements section, to detect material misstatements in respect of  irregularities, including 
fraud. The extent to which our procedures are capable of  detecting irregularities, including fraud, is 
detailed below. 

Based on our understanding of  the parent company and industry, we identified that the principal 
risks of  non-compliance with laws and regulations related to compliance with being a listed company, 
and we considered the extent to which non-compliance might have a material effect on the financial 
statements.  We  also  considered  those  laws  and  regulations  that  have  a  direct  impact  on  the 
preparation  of   the  financial  statements  such  as  the  Companies  Act  2006.  We  evaluated 
management’s incentives and opportunities for fraudulent manipulation of  the financial statements 
(including the risk of  override of  controls), and determined that the principal risks were related to 
misappropriation of  cash. Audit procedures performed by the engagement team included: 

(cid:129) Discussions with management and internal legal counsel including consideration of  known or 

suspected instances of  non-compliance with laws and regulations and fraud. 

(cid:129) Review of  minutes of  meeting with the Board of  Directors. 

(cid:129)

Identifying and testing journal entries, in particular any journal entries posted with unusual account 
combinations impacting cash. 

There are inherent limitations in the audit procedures described above. We are less likely to become 
aware of  instances of  non-compliance with laws and regulations that are not closely related to events 
and  transactions  reflected  in  the  financial  statements.  Also,  the  risk  of   not  detecting  a  material 
misstatement due to fraud is higher than the risk of  not detecting one resulting from error, as fraud 
may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or 
through collusion. 

Key audit matters 
Key audit matters are those matters that, in the auditors’ professional judgement, were of  most 
significance  in  the  audit  of   the  financial  statements  of   the  current  period  and  include  the  most 
significant assessed risks of  material misstatement (whether or not due to fraud) identified by the 
auditors, including those which had the greatest effect on: the overall audit strategy; the allocation 
of  resources in the audit; and directing the efforts of  the engagement team. These matters, and any 
comments we make on the results of  our procedures thereon, were addressed in the context of  our 
audit of  the financial statements as a whole, and in forming our opinion thereon, and we do not 
provide a separate opinion on these matters. 

This is not a complete list of  all risks identified by our audit. 

Valuation of  investment in Orchard Therapeutics (Europe) Limited is a new key audit matter this year. 
Otherwise, the key audit matters below are consistent with last year.

Key audit matter                                                      How our audit addressed the key audit matter 

Impact of  Covid-19 
The COVID-19 pandemic, and measures taken 
by governments in order to contain COVID-19 as 
well  as  to  provide  support  to  businesses, 
continues to potentially have a significant impact 
on the operations, liquidity and/or solvency of  the 
company. The COVID-19 outbreak continues to 
create uncertainty about the long term outlook of  
most entities as measures taken by governments 
might change, the disease might spread further, 
and the economic crisis may deepen, all of  which 
could have an impact on the company.

Valuation of  investment in Orchard Therapeutics 
(Europe) Limited 
The parent company holds an investment in its 
subsidiary,  Orchard  Therapeutics 
(Europe) 
Limited. The reduction in the market capitalisation 
of  Orchard Therapeutics plc, implied by its share 
price at 31 December 2020 (and the fact that this 
below the carrying value of  the investment) is an 
the 
indicator  of   potential 
investment. Because of  the uncertainties involved 
in  a  value  in  use  calculation  management 
assessed 
to  be 
representative  of   the  fair  value  less  costs  of  
disposal  of   the  investment  and  therefore  the 
realisable  value.  As  a  result  an  impairment  of  
$792.8m has been recorded.

the  market  capitalisation 

impairment  of  

We considered the impact of  COVID-19 on the 
company’s  control  environment  and  have 
performed walkthroughs of  the controls in place 
throughout the pandemic to understand how the 
company’s  controls  have  been  adapted  as  a 
result of  remote working. We have concluded that 
the control environment has not been significantly 
impacted by COVID-19 working practices given 
that the business and staff  are well equipped to 
work remotely in an effective manner. We have 
also  assessed  the  impact  of   COVID-19  on  the 
ability  of   the  company  to  continue  as  a  going 
concern  and  deem  there  not  be  a  significant 
impact,  given  the  slowdown  in  expenditure 
caused  by  the  pandemic,  and  there  being 
sufficient  cash  in  the  group  to  provide  runway 
into 2023 as a result of  the existing cash reserves 
held,  taking  into  account  the  fundraise  in 
February 2021 which generated net proceeds of  
$144m. 

We  have  performed  the  following  procedures 
over 
impairment  assessment  which 
management have prepared:  

the 

– Assessed management’s impairment model 
and calculation for compliance with UK GAAP 
(FRS 102).  

– Corroborated  the  inputs  to  the  model  and 
validated  these  to  external  sources  or  our 
audit testing performed in other areas.  

– Recalculated 

the 

impairment 

to  be 
recognised in the year as the excess of  the 
carrying  value  of   the  investment  over  its 
recoverable  amount,  which  is  determined 
using a fair value less costs to sell method.  

– Reviewed  the  disclosures  in  the  financial 

statements. 

No exceptions have been noted from the work 
performed.

How we tailored the audit scope  
We tailored the scope of  our audit to ensure that we performed enough work to be able to give an 
opinion  on  the  financial  statements  as  a  whole,  taking  into  account  the  structure  of   the  parent 
company, the accounting processes and controls, and the industry in which it operates. 

Although the parent company is a UK company, most procedures have been performed by PwC US 
as component auditors. We instructed PwC US to report on the special purpose financial information 
of  the parent company prepared under US GAAP, and we have performed testing on the adjustments 
posted by management to prepare the parent company financial statements under FRS 102. 

Materiality 
The scope of  our audit was influenced by our application of  materiality. We set certain quantitative 
thresholds for materiality. These, together with qualitative considerations, helped us to determine the 
scope of  our audit and the nature, timing and extent of  our audit procedures on the individual financial 
statement line items and disclosures and in evaluating the effect of  misstatements, both individually 
and in aggregate on the financial statements as a whole. 

Based on our professional judgement, we determined materiality for the financial statements as a 
whole as follows: 

Overall parent company materiality US$4,546,000.00 (2019: US$5,960,000.00). 

How we determined it

1% of  total assets 

Rationale for benchmark applied

We believe that total assets is the primary measure used by 
the shareholders in assessing the performance and position 
of  the parent company and reflects the parent company’s 
principal activity as a holding company. 

We  use  performance  materiality  to  reduce  to  an  appropriately  low  level  the  probability  that  the 
aggregate of  uncorrected and undetected misstatements exceeds overall materiality. Specifically, 
we use performance materiality in determining the scope of  our audit and the nature and extent of  
our testing of  account balances, classes of  transactions and disclosures, for example in determining 
sample  sizes.  Our  performance  materiality  was  75%  of   overall  materiality,  amounting  to 
US$3,410,000.00 for the parent company financial statements. 

In determining the performance materiality, we considered a number of  factors – the history of  
misstatements,  risk  assessment  and  aggregation  risk  and  the  effectiveness  of   controls  –  and 
concluded that an amount at the upper end of  our normal range was appropriate. 

We agreed with those charged with governance that we would report to them misstatements identified 
during our audit above $243,000 (2019: $410,000) as well as misstatements below that amount that, 
in our view, warranted reporting for qualitative reasons. 

Conclusions relating to going concern 
Our evaluation of  the directors’ assessment of  the parent company’s ability to continue to adopt the 
going concern basis of  accounting included: 

(cid:129) A review of  management’s latest cash flow forecast, in which we have assessed the forecasts for 
reasonableness,  understood  the  planned  cash  outflows/inflows,  considered  management’s 
previous ability to forecast accurately and tested the funds received from the February 2021 
fundraise to supporting documentation. We also note that a significant proportion of  planned 
expenditure remains under management’s control for the foreseeable future, therefore if  cash 
were to run short, management have a number of  options under which discretionary expenditure 
could be reined back.

Based on the work we have performed, we have not identified any material uncertainties relating to 
events  or  conditions  that,  individually  or  collectively,  may  cast  significant  doubt  on  the  parent 
company’s ability to continue as a going concern for a period of  at least twelve months from when 
the financial statements are authorised for issue. 

In auditing the financial statements, we have concluded that the directors’ use of  the going concern 
basis of  accounting in the preparation of  the financial statements is appropriate. 

However,  because  not  all  future  events  or  conditions  can  be  predicted,  this  conclusion  is  not  a 
guarantee as to the parent company’s ability to continue as a going concern. 

Our  responsibilities  and  the  responsibilities  of   the  directors  with  respect  to  going  concern  are 
described in the relevant sections of  this report. 

Reporting on other information  
The other information comprises all of  the information in the Annual Report other than the financial 
statements and our auditors’ report thereon. The directors are responsible for the other information. 
Our opinion on the financial statements does not cover the other information and, accordingly, we do 
not express an audit opinion or, except to the extent otherwise explicitly stated in this report, any form 
of  assurance thereon.

information and, in doing so, consider whether the other information is materially inconsistent with 
the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially 
misstated. If  we identify an apparent material inconsistency or material misstatement, we are required 
to  perform  procedures  to  conclude  whether  there  is  a  material  misstatement  of   the  financial 
statements  or  a  material  misstatement  of   the  other  information.  If,  based  on  the  work  we  have 
performed,  we  conclude  that  there  is  a  material  misstatement  of   this  other  information,  we  are 
required to report that fact. We have nothing to report based on these responsibilities. 

With  respect  to  the  UK  Statutory  Strategic  Report  and  UK  Statutory  Directors’  Report,  we  also 
considered whether the disclosures required by the UK Companies Act 2006 have been included. 

Based on our work undertaken in the course of  the audit, the Companies Act 2006 requires us also 
to report certain opinions and matters as described below. 

UK Statutory Strategic Report and UK Statutory Directors’ Report 
In our opinion, based on the work undertaken in the course of  the audit, the information given in the 
UK Statutory Strategic Report and UK Statutory Directors’ Report for the year ended 31 December 
2020 is consistent with the financial statements and has been prepared in accordance with applicable 
legal requirements. 

In light of  the knowledge and understanding of  the parent company and its environment obtained in 
the course of  the audit, we did not identify any material misstatements in the UK Statutory Strategic 
Report and UK Statutory Directors’ Report.

STATEMENT OF DIRECTORS’ RESPONSIBILITIES IN 
RESPECT OF THE FINANCIAL STATEMENTS

The  directors  are  responsible  for  preparing  the  Annual  Report  and  the  financial  statements  in 
accordance with applicable law and regulation. 

Company law requires the directors to prepare financial statements for each financial year. Under 
that law the directors have prepared the group financial statements in accordance with United States 
Generally Accepted Accounting Principles (US GAAP) and parent company financial statements in 
accordance  with  United  Kingdom  Generally  Accepted  Accounting  Practice  (United  Kingdom 
Accounting Standards, comprising FRS 102 “The Financial Reporting Standard applicable in the UK 
and Republic of  Ireland”, and applicable law). 

Under company law, directors must not approve the financial statements unless they are satisfied 
that they give a true and fair view of  the state of  affairs of  the group and parent company and of  the 
profit or loss of  the group for that period. In preparing the financial statements, the directors are 
required to: 

(cid:129)

(cid:129)

select suitable accounting policies and then apply them consistently; 

state whether applicable accounting policies as issued by United States Generally Accepted 
Accounting Principles (US GAAP) have been followed for the group financial statements and 
United Kingdom Accounting Standards, comprising FRS 102 have been followed for the parent 
company financial statements, subject to any material departures disclosed and explained in the 
financial statements; 

(cid:129) make judgements and accounting estimates that are reasonable and prudent; and 

(cid:129) prepare the financial statements on the going concern basis unless it is inappropriate to presume 

that the group and parent company will continue in business. 

The directors are also responsible for safeguarding the assets of  the group and parent company 
and  hence  for  taking  reasonable  steps  for  the  prevention  and  detection  of   fraud  and  other 
irregularities. 

The directors are responsible for keeping adequate accounting records that are sufficient to show 
and explain the group’s and parent company’s transactions and disclose with reasonable accuracy 
at any time the financial position of  the group and parent company and enable them to ensure that 
the financial statements and the Directors’ Remuneration Report comply with the Companies Act 
2006.

UK STATUTORY STRATEGIC REPORT 

Introduction 
The  directors  of   Orchard  Therapeutics  plc  (which  together  may  be  referred  to  as  “Company”, 
“Orchard”, “we”, “us”, or “our”) present their UK Statutory Strategic Report on the Group and the 
audited consolidated financial statements for the year ended 31 December 2020. Orchard also filed 
with the U.S. Securities and Exchange Commission (the “SEC”) its Annual Report on Form 10-K for 
the year ended 31 December 2020, which may contain additional disclosures regarding some of  the 
matters discussed in this report. 

Corporate Information 
We were originally incorporated under the laws of  England and Wales in August 2018 as Orchard 
Rx Limited (now known as Orchard Therapeutics plc) to become a holding company for Orchard 
Therapeutics (Europe) Limited (previously known as Orchard Therapeutics Limited). Orchard Rx 
Limited subsequently re-registered as a public limited company and its name was changed from 
Orchard Rx Limited to Orchard Therapeutics plc in October 2018. Orchard Therapeutics (Europe) 
Limited was originally incorporated under the laws of  England and Wales in September 2015 as 
Newincco 1387 Limited and subsequently changed its name to Orchard Therapeutics Limited in 
November 2015 and to Orchard Therapeutics (Europe) Limited in October 2018.  

To  date,  we  have  financed  our  operations  primarily  with  proceeds  from  the  sale  of   American 
Depositary Shares (ADSs) in our IPO and follow-on offering, proceeds from the sale of  convertible 
preferred shares, reimbursements from our research agreement with the University of  California 
Los Angeles and, following transfer of  the adenosine deaminase severe combined immunodeficiency 
(ADA-SCID) research program sponsorship from UCLA to us in July 2018, a grant from the California 
Institute of  Regenerative Medicine (“CIRM”), and our Credit Facility.  

On February 27, 2020, we entered into a Sales Agreement with Cowen and Company, LLC, as agent, 
relating to an “at the market offering,” pursuant to which we may issue and sell ADSs representing 
our ordinary shares, having an aggregate offering price of  up to $100.0 million. As of  December 31, 
2020, we have not sold any shares under the Sales Agreement. 

Through December 31, 2020, we have received net proceeds of  $335.2 million from the sale of  ADSs 
in our initial public offering and follow-on offering, net proceeds of  $283.4 million from sales of  
convertible preferred shares, $24.5 million in net proceeds from our Credit Facility, receipts associated 
with our United Kingdom research and development tax credit of  $33.9 million, proceeds from share 
issuances from employee equity plans of  $7.1 million, and reimbursement of  $8.2 million from our 
agreement with CIRM, which was formerly a subcontract agreement with UCLA. As of  December 
31, 2020, we had cash, cash equivalents, and marketable securities of  $191.9 million, excluding 
restricted cash.  

On February 9, 2021, we issued and sold (i) 20,900,321 ordinary shares, nominal value £0.10 per 
share, at a purchase price of  $6.22 per share (the “Purchase Price”), which was the closing sale 
price of  our ADSs on the Nasdaq Global Select Market on February 4, 2021, and (ii) 3,215,434 non-
voting  ordinary  shares,  nominal  value  £0.10  per  share,  at  the  Purchase  Price  (the  “Private 
Placement”). The Private Placement resulted in net proceeds to us of  approximately $144.0 million 
after deducting placement agent fees. The ordinary shares and non-voting ordinary shares were sold 
pursuant to a securities purchase agreement we entered into with the purchasers named therein on 
February 4, 2021.

Business Overview (including company strategy, business model, and key 
performance indicators) 
We are a global gene therapy company dedicated to transforming the lives of  people affected by 
rare diseases through the development of  innovative, potentially curative gene therapies. Our ex vivo 
autologous  hematopoietic  stem  cell,  or  HSC,  gene  therapy  approach  harnesses  the  power  of  
genetically modified blood stem cells and seeks to correct the underlying cause of  disease in a 
single administration. We seek to achieve this outcome by utilizing a lentiviral vector to introduce a 
functional copy of  a missing or faulty gene into the patient’s own, or autologous, HSCs through an 
ex vivo process, resulting in a gene-modified cellular drug product that can then be administered to 
the patient at the bedside.  

To date, over 160 patients have been treated with our product candidates across seven different 
diseases, with follow-up periods of  more than 10 years following a single administration. We believe 
the data observed across these development programs, in combination with our expertise in the 
development, manufacturing and commercialization of  gene and cell therapies, position us to provide 
potentially curative therapies to people suffering from a broad range of  diseases.  

We are currently focusing our ex vivo autologous HSC gene therapy approach on three therapeutic 
disease areas: neurodegenerative, immunological and blood disorders. Our portfolio includes two 
commercial-stage products approved in Europe, seven lentiviral-based product candidates in clinical-
stage development and several other product candidates in preclinical development. Our two lead 
programs are OTL-200, which was approved in the European Union, or EU, United Kingdom, or UK, 
Iceland, Liechtenstein and Norway under the brand name Libmeldy for eligible patients with early-
onset  metachromatic  leukodystrophy,  or  MLD,  and  OTL-103,  which  is  being  investigated  for  the 
treatment of  Wiskott Aldrich syndrome, or WAS. For each of  our lead product candidates, we are in 
ongoing discussions with regulatory authorities with respect to the clinical and other data required 
for future regulatory submissions. In late 2020, for instance, the U.S. Food & Drug Administration, or 
FDA, cleared our investigational new drug, or IND, application for OTL-200, and we plan to complete 
interactions with the FDA to determine the path to file a biologics license application, or BLA, by 
mid-2021. We plan to file a marketing authorization application, or MAA, for OTL-103 in Europe by 
year-end 2021 and a BLA for OTL-103 in the U.S. in 2022.  

We  have  a  broad  and  advanced  portfolio  of   commercial-stage  products,  and  research  and 
development-stage product candidates, and we believe our approach of  using lentiviral vectors to 
genetically modify HSCs has wide-ranging applicability to a large number of  indications. The ability 
of  HSCs to differentiate into multiple cell types allows us to deliver gene-modified cells to multiple 
physiological systems, including the central nervous system, immune system and red blood cell and 
platelet lineage, thereby potentially enabling the correction of  a wide range of  diseases. By leveraging 
the innate self-renewing capability of  HSCs that are engrafted in the bone marrow as well as the 
ability of  lentiviral vectors to achieve stable integration of  a modified gene into the chromosomes of  
HSCs,  our  gene  therapies  have  the  potential  to  provide  a  durable  effect  following  a  single 
administration.

The diseases we are targeting affect patients around the world, requiring an infrastructure to deliver 
gene therapies globally. In order to meet anticipated demand for our pipeline of  approved products 
and  product  candidates  still  in  development,  we  are  utilizing  our  existing  network  of   contract 
development and manufacturing organizations, or CDMOs, to manufacture lentiviral vectors and drug 
product. In addition, we have established process development capabilities in London, UK, and are 
leveraging technologies that will allow us to deliver our gene therapies globally.  

Cryopreservation of  our gene-modified HSCs is a key component of  our commercialization strategy 
to deliver potentially curative gene therapies to patients worldwide, facilitating both local treatment 
and local or cross-border product reimbursement. In anticipation of  commercialization, we developed 
cryopreserved formulations of  Libmeldy (OTL-200) and OTL-103 and are collecting supportive clinical 
data from patients treated with cryopreserved formulations to support the analytical comparability to 
the fresh cell formulations used in our registrational clinical trials. The registrational trials for all our 
earlier stage product candidates are expected to be conducted using a cryopreserved formulation.  

We have global commercial rights to all our clinical product candidates and plan to commercialize 
our gene therapies in key markets worldwide, including in Europe and the U.S. initially, subject to 
obtaining the necessary marketing approvals for these jurisdictions. We plan to deploy a focused 
commercial infrastructure to deliver Libmeldy and our product candidates, if  approved, to patients 
and are focused on working closely with all relevant stakeholders, including patients, caregivers, 
specialist physicians and payors, to ensure the widest possible post-approval access for our product 
candidates. In addition, we may rely on third parties to assist with regulatory submissions, disease 
awareness, patient identification and reimbursement in countries where local expertise is required 
or  where  we  do  not  have  a  direct  presence.  For  example,  in  January  2021,  we  announced 
partnerships with two regional specialty pharmaceutical companies with experience in rare genetic 
diseases to support us in the Middle East and Turkey. 

As  we  continue  to  develop  and  expand  our  portfolio,  we  believe  that  the  experience  of   our 
management  team  and  our  extensive  academic  relationships  are  key  strategic  strengths.  Our 
management team has extensive experience in rare diseases and in the manufacturing, preclinical

continued 

and clinical development and commercialization of  gene and cell therapies. In addition, we partner 
with leading academic institutions around the world, which are pioneers in ex vivo autologous HSC-
based gene therapy. We plan to leverage our internal expertise combined with our relationships with 
leading  academic  institutions  to  transition  our  lead  clinical-stage  product  candidates  to 
commercialization and continue to expand our portfolio of  ex vivo autologous HSC gene therapy 
products.  

Our ex vivo autologous HSC gene therapy approach  
Our ex vivo autologous HSC gene therapy approach seeks to transform a patient’s autologous HSCs 
into a gene-modified cellular drug product to treat the patient’s disease. HSCs are self-renewing cells 
that are capable of  differentiating into all types of  blood cells, including white blood cells, red blood 
cells, platelets and tissue resident macrophages, which include the microglia of  the central nervous 
system. HSCs can be obtained directly from the bone marrow, which requires administration of  a 
general anesthetic, or from the patient’s peripheral blood with the use of  mobilizing agents, which 
are agents that can move HSCs from the bone marrow into the peripheral blood for easier collection. 
The HSCs collected are then manufactured to insert a functional copy of  the missing or faulty gene. 
By delivering gene-modified HSCs back to patients, we seek to take advantage of  the self-renewing 
capability of  HSCs to enable a durable effect following a single administration, as has been seen in 
our commercial and development programs. Since these cells are recognized by the body as the 
patient’s own cells, the risks associated with using donor cells may be reduced. In addition, the ability 
of  HSCs to differentiate into multiple different cell types has the potential to enable the delivery of  
gene-modified cells to different physiological systems and allow the correction of  a broad range of  
different diseases.  

Clinical validation already exists for hematopoietic stem cell transplantation, or HSCT, an approach 
of  treating a patient with a genetic disease with HSCs contributed by a healthy donor individual, 
thereby using HSCs that contain a functioning copy of  the gene of  interest. However, this approach 
has significant limitations, including difficulties in finding appropriate genetically matched donors 
and the risk of  graft-versus-host disease, transplant-related rejection and mortality from these and 
other complications, and is therefore typically only offered on a limited basis. Furthermore, genetically 
modified cells can be used to express enzyme activity at supra-physiological levels, which we believe 
has the potential to overcome the limitations of  HSCT (where enzyme expression is generally limited 
to normal levels) to treat some neurometabolic disorders and improve the metabolic correction in 
neuronal cells before irreversible degeneration occurs. Our approach is intended to address these 
significant limitations of  HSCT.  

In a preclinical study conducted by one of  our scientific advisors and published in Proceedings of  
the National Academy of  Sciences of  the United States of  America, or PNAS, a subpopulation of  
gene-modified HSCs has evidenced the potential to cross the blood-brain barrier, engraft in the brain 
as microglia and express genes and proteins within the central nervous system, one of  the important 
physiological systems targeted by our HSC gene therapy approach. As published in PNAS, images 
taken during the study show a cross-section of  the brain of  a mouse that was infused intravenously 
with HSCs, which had been genetically modified using a lentiviral vector carrying green fluorescent 
protein, or GFP. The GFP expression observed throughout the brain illustrates the potential of  gene-
modified HSCs to cross the blood-brain barrier, engraft in the brain and express the functional protein 

Orchard Therapeutics plc  23

 
UK STATUTORY STRATEGIC REPORT 
continued 

throughout  the  brain,  thereby  potentially  addressing  a  range  of   diseases  that  affect  the  central 
nervous system. Libmeldy (OTL-200), for instance, leverages this same mechanism of  action to 
deliver gene-modified HSCs that can cross the blood-brain barrier and deliver a therapeutic gene 
that  can  prevent  neuronal  degeneration.  The  study  demonstrated  widespread  distribution  and 
expression of  GFP in the brain of  a mouse model following intravenous administration of  HSCs 
transduced with GFP encoding vector. 

With respect to Libmeldy (OTL-200) and each of  our product candidates, our ex vivo gene therapy 
approach utilizes a self-inactivating, or SIN, lentiviral vector to introduce a functional copy of  the 
missing  or  faulty  gene  into  the  patient’s  autologous  HSCs  through  an  ex  vivo  process  called 
transduction, resulting in a cellular drug product that can then be re-introduced into the patient. Unlike 
some other viral vectors, such as adeno-associated viral, or AAV, vectors, lentiviral vectors integrate 
into the chromosomes of  patients’ HSCs. We believe this allows us to achieve stable integration of  
the functional gene into the HSCs and can lead to durable expression of  the target protein by the 
gene-modified HSCs and their progeny after a single administration of  gene therapy. In contrast, 
because AAV vectors rarely integrate into the genome, the transgene is not passed on to all progeny 
when the cell divides, resulting in rapid dilution and loss of  the transgene among frequently dividing 
cells such as HSCs. Regarding immunogenicity, because in vivo delivery of  AAV places the vector 
into direct contact with the immune system and most individuals harbor some type of  pre-existing 
immunity, including neutralizing antibodies, to one or more types of  AAV vector, the incoming vector 
can be completely inactivated by the patient’s immune system. Furthermore, there have been reports 
that  certain  high  dose  applications  of   AAV  have  resulted  in  acute  and  severe  innate  immune 
responses that have proved lethal. With ex vivo delivery, however, the vector is not introduced directly 
into the body and vector elements are washed away in the laboratory such that there is little to no 
vector element left to present to the immune system. Our HSC gene therapies and product candidates 
are all manufactured ex vivo. Strimvelis is the only gammaretroviral vector-based gene therapy in our 
portfolio.  

The image below illustrates the steps in our approach to transform a patient’s autologous HSCs 
ex vivo into therapeutic product.

UK STATUTORY STRATEGIC REPORT 
continued 

Initial clinical trials conducted using our product candidates utilized a fresh product formulation, 
resulting in a limited drug product shelf  life. We plan to market Libmeldy (OTL-200) and our current 
and any future product candidates, if  approved, in a cryopreserved product formulation, which is 
designed to extend the drug product shelf  life and enable the shipment of  the drug product to 
specialized  treatment  centers,  allowing  patients  to  receive  treatment  closer  to  their  home  while 
leveraging more centralized manufacturing. Cryopreservation also allows us to conduct a number of  
quality control tests on the genetically modified HSCs prior to introducing them into the patient.  

In addition, certain of  our clinical-stage product candidates have been evaluated in registrational 
trials using drug product derived from HSCs extracted from the patients’ bone marrow. To optimize 
our potential product label and the number of  patients that we may be able to treat, as part of  any 
BLA or MAA submission for such product candidates, we plan to demonstrate comparability between 
drug product manufactured using HSCs derived from the patients’ peripheral blood and drug product 
manufactured using HSCs derived from the patients’ bone marrow. In cases where clinical trials were 
conducted  using  vector  and/or  drug  product  manufactured  at  academic  centers,  we  plan  to 
demonstrate comparability between vector and/or drug product manufactured by our third party 
commercial CDMOs with vector and drug product manufactured at such academic centers.  

Initially, we are employing our ex vivo autologous HSC gene therapy approach in three therapeutic 
disease  areas:  neurodegenerative,  immunological  and  blood  disorders.  Data  from  clinical  trials 
suggest  that  ex  vivo  autologous  HSC  gene  therapy  has  the  potential  to  provide  generally  well-
tolerated, sustainable and improved outcomes over existing standards of  care for diseases in these 
areas. We believe that we can apply our approach beyond our initial target indications to treat an 
even broader range of  diseases.  

Our strategy  
We are building a leading, global, fully-integrated gene therapy company focused on transforming 
the  lives  of   people  affected  by  severe  diseases.  To  achieve  this,  we  are  pursuing  the  following 
strategies: 

(cid:129)

Launch Libmeldy (OTL-200) for the treatment of  eligible patients with early-onset MLD in Europe, 
following  its  approval  in  December  2020  and  expand  geographically  into  new  markets  as 
regulatory approvals are obtained 

(cid:129) Advance our clinical-stage product candidates towards marketing approvals, with a near term 
focus on OTL-200 for MLD in the U.S., OTL-103 for WAS in Europe and the U.S., and our clinical-
stage programs in neurodegenerative disorders, including OTL-203 for MPS-I and OTL-201 for 
MPS-IIIA 

(cid:129)

(cid:129)

Leverage the power of  our therapeutic approach to investigate the potential of  HSC gene therapy 
in larger indications  

Invest in new technologies and innovations to continue to improve our manufacturing processes 
for lentiviral vector and drug product and reduce costs of  goods manufactured 

Orchard Therapeutics plc  25

 
UK STATUTORY STRATEGIC REPORT 
continued 

(cid:129) Establish end-to-end process development, manufacturing and supply chain capabilities, initially 

through third parties and internally over time 

(cid:129) Establish a patient-centric, global commercial infrastructure, including with third parties in certain 

regions where we do not have a direct presence 

(cid:129) Execute a business development strategy to leverage our HSC gene therapy approach, expand 
geographically, accelerate time-to-market or attract disease-area expertise to optimize the value 
of  our portfolio of  product candidates or expand into new indications 

Our pipeline  
We have one of  the deepest and most advanced gene therapy pipelines in the industry spanning 
multiple therapeutic areas where the disease burden on children, families and caregivers is immense 
and current treatment options are limited or do not exist. Our programs focused on neurodegenerative 
disorders consist of  our commercial program approved in Europe, Libmeldy (OTL-200) for MLD, two 
clinical proof  of  concept-stage programs, OTL-203 for mucopolysaccharidosis type I, or MPS-I, and 
OTL-201 for mucopolysaccharidosis type IIIA, or MPS-IIIA, and three preclinical programs, OTL-202 
for  mucopolysaccharidosis  type  IIIB,  or  MPS-IIIB,  OTL-204  for  frontotemporal  dementia  with 
progranulin  mutations,  or  GRN-FTD,  and  OTL-205  for  amyotrophic  lateral  sclerosis,  or  ALS.  Our 
programs  in  immunological  disorders  consist  of   our  commercial  program  approved  in  Europe, 
Strimvelis for adenosine deaminase severe combined immunodeficiency, or ADA-SCID, two advanced 
registrational clinical programs, OTL-101 for ADA-SCID and OTL-103 for WAS, one clinical proof  of  
concept-stage program, OTL-102 for X-linked chronic granulomatous disease, or X-CGD, and one 
preclinical  program,  OTL-104  for  Crohn’s  disease  with  mutations  in  the  nucleotide-binding 
oligomerization  domain-containing  protein  2,  or  NOD2-CD.  Our  clinical  proof   of   concept-stage 
program,  OTL-300  for  transfusion-dependent  beta-thalassemia,  or  TDT,  is  focused  on  a  life-
threatening blood disorder.  

The nature of  our autologous gene therapy product candidates precludes the conduct of  Phase 1 
safety studies in healthy volunteers. Moreover, considering the indications our product candidates 
are intended to treat, which are often fatal without treatment and which are rare indications with high 
unmet  medical  need,  we  believe  our  clinical  programs  will  generally  be  eligible  to  proceed  to 
registration based on a single pivotal study given the bioethical considerations regarding the conduct 
of   randomized,  double-blind  and  placebo-controlled  clinical  trials  with  gene  therapies  for  such 
indications. For purposes of  this Annual Report, we refer to an exploratory study, which is sometimes 
referred to as a Phase 1 or Phase 1/2 clinical trial, as a proof  of  concept trial, and a confirmatory 
efficacy  and  safety  study  to  support  submission  of   a  potential  marketing  application  with  the 
applicable regulatory authorities, which is sometimes referred to as a Phase 2/3 or Phase 3 clinical 
trial or a pivotal trial, as a registrational trial.

The status of  these programs is outlined below: 

Neurodegenerative Disorders  

Gene therapy for treatment of  MLD  
Disease overview  
MLD is a rare and life-threatening inherited disease of  the body’s metabolic system occurring in 
approximately one in every 100,000 live births in most regions of  the world. Higher incidence rates 
are reported in geographies of  higher consanguinity, such as Turkey and the Middle East. MLD is 
caused  by  a  mutation  in  the  arylsulfatase-A,  or  ARSA,  gene  that  results  in  the  accumulation  of  
sulfatides in the brain and other areas of  the body, including the liver, gallbladder, kidneys, and/or 
spleen. Over time, the nervous system is damaged, leading to neurological problems such as motor, 
behavioral and cognitive regression, severe spasticity and seizures. Patients with MLD gradually lose 
the ability to move, talk, swallow, eat and see. In its late infantile form, mortality at five years from 
onset is estimated at 50% and 44% at 10 years for juvenile patients. 

Limitations of  current therapies  
Prior to the approval of  Libmeldy (OTL-200) in Europe, there were no effective treatments or approved 
therapies for MLD. Palliative care options involve medications for seizures and pain, antibiotics and 
sedatives, on a case-by-case basis, as well as physiotherapy, hydrotherapy and tube feeding or 
gastrostomy  when  patients  can  no  longer  eat  without  assistance.  Palliative  care  addresses  the 
symptoms of  MLD but does not slow or reverse the progression of  the underlying disease. HSCT 
has limited and variable efficacy in arresting disease progression and, as a result, HSCT is not 
considered to be a standard of  care for this disease. MLD patients, their caregivers and families, 
and the healthcare system have faced significant burdens given the severity of  the disease and the 
lack of  effective treatments.  

Orchard Therapeutics plc  27

 
 
UK STATUTORY STRATEGIC REPORT 
continued 

Our solution, Libmeldy (OTL-200) for treatment of  MLD 
OTL-200 is designed as a one-time therapy that aims to correct the underlying genetic cause of  MLD, 
offering eligible patients the potential for long-term positive effects on cognitive development and 
maintenance of  motor function at ages at which untreated patients show severe motor and cognitive 
impairments. With OTL-200, a patient’s own HSCs are selected, and functional copies of  the ARSA 
gene are inserted into the genome of  the HSCs using a lentiviral vector before these genetically 
modified cells are infused back into the patient. The ability of  the gene-corrected HSCs to migrate 
across the blood-brain barrier into the brain, engraft, and express the functional enzyme has the 
potential to persistently correct the underlying disease with a single treatment.  

We obtained worldwide rights to this program through our asset purchase and license agreement 
with GSK, or the GSK Agreement. The clinical trials for this program have been conducted under a 
GSK-sponsored clinical trial authorization, which was transferred to us during the third quarter of  
2018.  

Libmeldy approval in Europe as Orphan Drug 
In December 2020, the European Commission granted full, or standard, marketing authorization for 
Libmeldy (OTL-200) (autologous CD34+ cell enriched population that contains hematopoietic stem 
and  progenitor  cells  transduced  ex  vivo  using  a  lentiviral  vector  encoding  the  human 
arylsulfatase-A (ARSA) gene) for the treatment of  early-onset MLD characterized by biallelic mutations 
in the ARSA gene leading to a reduction of  the ARSA enzymatic activity in children with i) late infantile 
or early juvenile forms, without clinical manifestations of  the disease, or ii) the early juvenile form, with 
early clinical manifestations of  the disease, who still have the ability to walk independently and before 
the onset of  cognitive decline. 

Libmeldy has received orphan drug designation from the EMA for the treatment of  MLD and orphan 
drug status was maintained at the time of  approval. We are continuing to follow patients in the clinical 
development program for up to 15 years as a post-marketing commitment, and data will be presented 
to regulators at agreed points in order to further characterize the long-term efficacy and safety of  
Libmeldy, particularly in the early symptomatic early juvenile population.  

Data Supporting the Clinical Profile of  Libmeldy  
The European Commission approval is supported by clinical studies of  Libmeldy in both pre- and 
early- symptomatic, early-onset MLD patients. Early-onset MLD encompasses the disease variants 
traditionally referred to as late infantile, or LI, and early juvenile, or EJ. 

Clinical efficacy was based on the integrated analysis of  results from 29 patients with early-onset 
MLD who were all treated with Libmeldy prepared as a fresh formulation: 

20 patients were treated in a registrational study (median follow-up of  4 years); 9 patients were 
treated in expanded access programs (median follow-up of  1.5 years) 

16 patients had a diagnosis of  LI MLD; 13 had a diagnosis of  EJ MLD 

At the time of  treatment, 20 patients were deemed pre-symptomatic; 9 were deemed early-
symptomatic 

Clinical safety was evaluated in 35 patients with early-onset MLD: 

29 patients from integrated efficacy analysis (described above)

Co-primary endpoints 
The co-primary endpoints of  the integrated efficacy analysis were Gross Motor Function Measure, 
or GMFM, total score and ARSA activity, both evaluated at 2 years post-treatment. Results of  this 
analysis indicate that a single-dose intravenous administration of  Libmeldy is effective in modifying 
the disease course of  early-onset MLD in most patients. 

Pre-symptomatic LI and EJ patients treated with Libmeldy experienced significantly less deterioration 
in motor function at 2 years and 3 years post-treatment, as measured by GMFM total score, compared 
to age and disease subtype-matched untreated patients (p≤0.008). The mean difference between 
treated pre-symptomatic LI patients and age-matched untreated LI patients was 71.0% at year 2 and 
79.8% at year 3. Similarly, the mean difference between treated pre-symptomatic EJ patients and 
age-matched untreated EJ patients was 52.4% at year 2 and 74.9% at year 3. Although not statistically 
significant, a clear difference in GMFM total score was also noted between treated early-symptomatic 
EJ patients and age-matched untreated EJ patients (28.7% at year 2; p=0.350 and 43.9% at year 3; 
p=0.054). 

A  statistically  significant  increase  in  ARSA  activity  in  peripheral  blood  mononuclear  cells  was 
observed at 2 years post-treatment compared to pre-treatment in both pre-symptomatic patients 
(20.0-fold increase; p<0.001) and early-symptomatic patients (4.2-fold increase; p=0.004). 

At  the  time  of   the  integrated  data  analysis,  all  treated  LI  patients  were  alive  with  a  follow-up 
post-treatment  up  to  7.5  years  and  10  out  of   13  treated  EJ  patients  were  alive  with  a  follow-up 
post-treatment of  up to 6.5 years. No treatment-related mortality has been reported in patients treated 
with Libmeldy. 

Key secondary endpoints 
For EJ patients who were early-symptomatic when treated with Libmeldy, meaningful effects on motor 
development  were  demonstrated  when  these  patients  were  treated  before  entering  the  rapidly 
progressive phase of  the disease (IQ≥85 and Gross Motor Function Classification, or GMFC, ≤1). By 
4 years post-disease onset, an estimated 62.5% of  treated, early-symptomatic EJ MLD patients 
survived  and  maintained  locomotion  and  ability  to  sit  without  support  compared  with  26.3%  of  
untreated early-symptomatic EJ MLD patients, representing a delay in disease progression following 
treatment with Libmeldy. 

A secondary efficacy endpoint that measured cognitive and language abilities as quantified by 
Intelligence Quotient/Development Quotient, or IQ/DQ, found in the treated LI subgroup, 12 out of  
15 assessed patients had a fairly constant IQ/DQ, within the normal range (IQ/DQ score of  100 +/- SD 
of   15)  throughout  follow-up.  All  but  two  of   these  patients  (i.e.,  one  pre-symptomatic  and  one 
early-symptomatic)  remained  above  the  threshold  of   severe  mental  disability  (IQ/DQ>55)  at 
chronological ages at which all 14 untreated comparator LI patients showed evidence of  severe 
cognitive impairment, which is defined as IQ/DQ below 55 and close to zero. Of  the 10 surviving EJ 
patients, all 4 pre-symptomatic patients and 4 out of  6 early-symptomatic patients showed normal 
IQ/DQ throughout follow-up. In contrast, 11 out of  12 untreated EJ patients showed evidence of  
severe cognitive impairment during follow-up. 

Clinical trial with cryopreserved drug formulation 
The cryopreserved formulation of  OTL-200 is being studied in a clinical trial of  pediatric patients with 
pre-symptomatic LI , or pre- to early-symptomatic EJ in Milan, Italy.

The  primary  goal  of   this  clinical  trial  is  to  assess  the  safety  and  efficacy  of   a  cryopreserved 
formulation of  OTL-200 in early-onset MLD patients, as measured by improvement in gross motor 
function and ARSA activity levels in the patients’ blood cells as well as overall survival. Secondary 
goals for this clinical trial include assessment of  cognitive function through IQ.  

Ten patients were treated in this trial between April 2017 and April 2020. All patients tolerated the 
administration well and for those with enough follow-up post-treatment, preliminary evidence of  
engraftment and restoration of  ARSA activity in peripheral blood to supraphysiological levels and in 
cerebral spinal fluid, or CSF, to normal levels has been shown.  

Data Supporting Safety Profile of  Libmeldy 
At the time of  the integrated data analysis in December 2019, which data set consisted of  29 patients 
treated with the fresh (investigational) formulation, all treated LI patients were alive with a follow-up 
post-treatment up to 7.5 years, and 10 out of  13 treated EJ patients were alive with a follow-up post-
treatment of  up to 6.5 years. No treatment-related mortality has been reported in patients treated 
with Libmeldy. 

The median duration of  follow-up in the first nine patients treated with the cryopreserved (commercial) 
formulation was 15 months as of  March 2020. 

The most common adverse reaction attributed to Libmeldy was presence of  anti-ARSA antibodies, 
or AAA. Five out of  35 patients tested positive for AAA at various post-treatment time points. Antibody 
titers were generally low and resolved either spontaneously or after a short course of  rituximab. In all 
patients with positive AAA test results, no negative effects were observed in the post-treatment ARSA 
activity of  peripheral blood or bone marrow cellular subpopulations nor in the ARSA activity within 
the  cerebrospinal  fluid.  In  addition  to  the  risk  associated  with  the  gene  therapy,  treatment  with 
Libmeldy is preceded by other medical interventions, namely bone marrow harvest or peripheral 
blood mobilization and apheresis, followed by myeloablative conditioning, which carry their own risks. 
During the clinical studies, the safety profiles of  these interventions were consistent with their known 
safety and tolerability. 

For more details, please see the Summary of  Product Characteristics, or SmPC, for Libmeldy. 

Additional clinical trial in Europe 
A clinical trial in late juvenile patients with MLD is open for recruitment in Milan, Italy. 

OTL-200 development in the U.S. 
OTL-200 has received orphan drug designation for the treatment of  MLD as well as Rare Pediatric 
Disease designation. In late 2020, the FDA cleared our IND application for OTL-200 in the U.S., and 
in January 2021, FDA granted regenerative medicine advanced therapy, or RMAT, designation for 
OTL-200. The IND includes a Phase 3b study with inclusion of  early symptomatic early juvenile MLD 
patients and a prospective planned analysis of  data from patients already treated in clinical studies 
in Italy. We plan to complete interactions with the FDA by mid-2021 to determine the path to file a 
biologics license application, or BLA, with the FDA. In parallel, we plan to initiate a Phase 3b clinical 
study in the early symptomatic early juvenile MLD patient population, which is planned to commence 
at a study site in the U.S. in mid-2021 and to be completed as post-BLA commitment.

Gene therapy for treatment of  MPS-I 
Disease overview  
Mucopolysaccharidosis  type  I  is  a  lysosomal  storage  disease  caused  by  a  deficiency  of   the 
lysosomal enzyme alpha-L-iduronidase, or IDUA. Inherited deficiency of  IDUA is responsible for MPS-
I. Without treatment, clinical manifestations of  this severe disease include skeletal abnormalities with 
severe  orthopedic  manifestations,  hepatosplenomegaly,  neurodevelopmental  decline,  sight  and 
hearing disturbances, cardiovascular and respiratory problems leading to death in early childhood. 
IDUA deficiency can result in a wide range of  clinical severity, with 3 major recognized clinical entities: 
Hurler, or MPS-IH, Scheie, or MPS-IS, and Hurler-Scheie, or MPS-IH/S, syndromes. Hurler and Scheie 
syndromes represent phenotypes at the severe and attenuated ends of  the MPS-I clinical spectrum, 
respectively. 

The median age of  diagnosis for MPS-IH is 12 months; most affected children are diagnosed before 
18 months of  age. Infants affected by MPS-IH usually appear normal at birth, but may develop 
inguinal or umbilical hernias in the first six months, and develop the characteristic somatic phenotype 
over the first few years of  life.  

The approximate incidence of  MPS-I is of  one in 100,000 live births. Approximately 60 percent of  
children born with MPS-I have MPS-IH. 

Limitations of  current therapies  
Allogeneic-HSCT with pre- and peri-transplant enzyme replacement therapy, or ERT, from diagnosis 
to engraftment has been established as the standard of  care for MPS-IH patients diagnosed before 
the age of  30 months and with presumed MPS-IH (presence of  family history and/or clinical signs 
and symptoms compatible with MPS-IH, i.e., phenotypic diagnosis based on clinical expertise), 
and/or  homozygosity  or  compound  heterozygosity  for  mutations  associated  with  the  severe 
phenotype.  The  recommendation  that  HSCT  should  be  standard  of   care  for  MPS-IH  patients  is 
endorsed by the European Society for Blood and Marrow Transplantation and the American Society 
for Transplantation and Cellular Therapy. 

Despite its established position in treatment algorithms, allogeneic-HSCT can result in alloreactive 
complications, including potentially fatal graft versus host disease, or GvHD, particularly when the 
degree of  matching between graft donor and recipient is low. Additionally, although it may stabilize 
cognitive decline, life-threatening or severely debilitating cognitive, neurological, orthopedic, cardiac, 
respiratory and ophthalmic manifestations of  MPS-IH have been reported during long-term post-
HSCT follow-up.  

Our solution, OTL-203 for treatment of  MPS-I  
Ex vivo autologous HSC gene therapy strategies aimed at correcting the genetic defect in patients 
could represent a significant improvement for the treatment of  MPS-I, notably MPS-IH the most severe 
and prevalent phenotype with the highest unmet medical need, when compared to current treatments.  

OTL-203 is a single administration, gene therapy product candidate consisting of  autologous CD34+ 
enriched HSPCs, derived from mobilized peripheral blood, genetically modified ex vivo with the 
lentiviral vector encoding for the IDUA complementary DNA, or cDNA. It is being developed as a 
cryopreserved formulation. Ex vivo autologous gene therapies, such as OTL-203, are designed to 
correct the genetic defect in patients’ own HSCs and their progeny by addition of  corrective cDNA. 
The OTL-203 mechanism of  action addresses the disease pathophysiology by restoring enzymatic 
IDUA  expression  in  peripheral  and  central  body  compartments  as  well  as  restoring  microglia 
homeostasis and its neuroprotective effects against the neurotoxic effects of  glycosaminoglycan, or 
GAG,  accumulation 
in  affected  cells.  We  have  obtained  worldwide  development  and 
commercialization rights to OTL-203 from Telethon Foundation and San Raffaele Hospital.

continued 

Autologous cells may be genetically modified to constitutively express supra-normal levels of  the 
therapeutic enzyme and become a quantitatively more effective source of  functional enzyme than 
wild-type cells, possibly also at the level of  the nervous system and bone.  

The  therapeutic  potential  of   this  approach  for  addressing  the  extensive  nervous  system 
manifestations of  MPS-IH is based on the contribution of  HSCs to the turnover of  CNS-resident 
microglia, demonstrated both in physiological and pathological conditions. Since microglia have been 
implicated in the pathogenesis of  a number of  neurodegenerative conditions, including LSDs. These 
cells should be considered a primary target cell type in therapeutic strategies for LSD with neurologic 
involvement such as MPS-IH. Moreover, compared to allogeneic transplantation, which is the current 
standard  of   care  for  MPS-IH  treatment,  the  autologous  nature  of   OTL-203  is  associated  with  a 
significantly reduced transplant-related morbidity and mortality and avoids the risks of  graft versus 
host disease. 

OTL-203 has received orphan drug and PRIME designation from the EMA as well as orphan drug 
designation and rare pediatric disease designation from the FDA for the treatment of  MPS-I.  

Ongoing clinical trials 
OTL-203 is currently being investigated in an ongoing, academic-sponsored clinical trial at the San 
Raffaele Hospital in Milan, Italy to establish proof  of  concept. The study is a prospective, single dose, 
single center, non-randomized, open label study involving a single administration of  OTL-203 in eight 
patients with a confirmed diagnosis of  MPS-IH. The study is fully enrolled using a cryopreserved 
formulation of  OTL-203.  

The patients evaluated in this trial include pediatric MPS-IH patients from 14 to 35 months of  age at 
the time of  treatment and will be followed for at least 2 years post-treatment in the context of  the 
proof  of  concept study and then continue to be evaluated in a long-term follow-up study.  

Interim results for all eight patients were presented at the WORLD Symposium in February 2021. As 
of   November  2020,  follow-up  in  all  patients  reached  at  least  12  months  and  the  interim  data 
supporting  clinical  proof-of-concept  illustrated  that  treatment  with  OTL-203  was  generally  well-
tolerated with a safety profile consistent with the selected conditioning regimen. IDUA antibodies 
present prior to gene therapy as a result of  ERT were not seen in any patient within two months 
following  treatment.  In  addition,  ERT  was  discontinued  at  least  three  weeks  prior  to  any  patient 
receiving gene therapy treatment, and no patients had re-started ERT post-treatment. 

In terms of  biomarker data, treatment demonstrated rapid and sustained metabolic correction with 
all patients achieving supra-physiological IDUA expression in dried blood spot samples at 12 months 
(a  primary  efficacy  endpoint).  Associated  with  this,  the  results  demonstrated  increased  IDUA 
expression in the CSF, with reduction of  GAGs in CSF and normalization of  GAG levels in urine. 

All eight patients treated with OTL-203 showed stable cognitive function, motor function and growth 
within  the  normal  range  at  multiple  data  points  post-treatment.  For  instance,  stable  cognitive 
performance, as evaluated by cognitive age-equivalence using the Bayley scale, was shown in all 
patients post-treatment, with follow-up ranging from 6 months to 2 years. Longitudinal growth that 
was within age-appropriate reference ranges was seen in all patients post-treatment, with follow-up 
ranging  from  9  months  to  2  years.  Furthermore,  stable  motor  function  was  seen  in  all  patients 
compared to pre-treatment, with follow-up ranging from 9 months to 1.5 years, and improved range

of  motion (less joint stiffness) was also shown in all patients compared to pre-treatment, with follow-
up ranging from 9 months to 1.5 years. 

We have been granted parallel scientific advice by the FDA and EMA on this program. We intend to 
seek feedback from the regulatory agencies, including on the study design and CMC development, 
in advance of  initiating an international multi-center registrational study for OTL-203 by year-end 
2021, subject to filing an IND in the U.S. and necessary clinical trial applications, or CTAs, in Europe.

Gene therapy for treatment of  MPS-IIIA and MPS-IIIB  
Disease overview  
MPS-IIIA,  also  known  as  Sanfilippo  syndrome  type  A,  and  MPS-IIIB,  also  known  as  Sanfilippo 
syndrome 
that  cause  accumulation  of  
glycosaminoglycan in cells, tissues and organs, particularly in the brain. Within one to two years after 
birth, MPS-IIIA and MPS-IIIB patients begin to experience progressive neurodevelopmental decline, 
including speech delay and eventual loss of  language, behavioral disturbances, and potentially 
severe  dementia.  Ultimately,  most  patients  with  MPS-IIIA  progress  to  a  vegetative  state.  Life 
expectancy for patients with MPS-IIIA and MPS-IIIB is between 10 to 25 years and 15 to 30 years, 
respectively.  

life-threatening  metabolic  diseases 

The incidence of  MPS-IIIA and MPS-IIIB are currently estimated to be one in 100,000 and one in 
200,000 live births per year, respectively.  

Limitations of  current therapies  
Currently, there are no effective treatments or approved therapies for MPS-IIIA and MPS-IIIB. Palliative 
care options involve medications for seizures and pain, antibiotics and sedatives, on a case-by-case 
basis, as well as physiotherapy, hydrotherapy and tube feeding or gastrostomy when patients can 
no longer eat without assistance. Palliative care addresses the symptoms of  MPS-IIIA and MPS-IIIB 
but does not slow or reverse the progression of  the underlying disease. Systemic ERT is not an 
approved treatment option and HSCT is not considered to be an effective treatment option for these 
diseases.  The  severity  of   symptoms  and  lack  of   an  effective  treatment  option  to  manage  these 
symptoms is a significant burden to MPS-IIIA and MPS-IIIB patients, their caregivers and families 
and healthcare systems.  

Our solutions, OTL-201 for treatment of  MPS-IIIA and OTL-202 for treatment of  MPS-IIIB  
We are developing OTL-201 and OTL-202 as ex vivo autologous HSC gene therapies for treatment 
of  patients with MPS-IIIA and MPS-IIIB, respectively. In both indications we believe preclinical studies 
in mice have shown that ex vivo autologous gene therapy has the potential to address the neurological 
manifestations  of   MPS-IIIA  and  MPS-IIIB.  We  have  obtained  worldwide  development  and 
commercialization rights to OTL-201 and OTL-202 from The University of  Manchester.  

OTL-201 has received orphan drug designation from the EMA and FDA for the treatment of  MPS-IIIA 
and has received rare pediatric disease designation from the FDA.  

Proof  of  concept trial in MPS-IIIA 
We are supporting a proof  of  concept trial for the treatment of  MPS-IIIA, which started enrollment in 
January 2020. The trial, which is being conducted by the Royal Manchester Children’s Hospital and 
sponsored  by  the  Manchester  University  NHS  Foundation  Trust,  is  expected  to  enroll  up  to  five 
patients. As of  February 2021, four patients were enrolled in the study and three patients had been 
treated with OTL-201 in the ongoing proof  of  concept trial.

Interim  results  were  presented  at  the  WORLD  Symposium  in  February  2021  through  an  oral 
presentation. As of  February 2021, these preliminary results from the first three patients treated with 
OTL-201 showed promising tolerability, engraftment and biomarker data over the initial three-month 
follow-up  period.  For  instance,  the  treatment  has  been  generally  well-tolerated  in  the  first  three 
patients with no treatment-related SAEs, and all transplant-related SAEs and adverse events have 
resolved. Data supported evidence of  hematological engraftment, as illustrated by the rapid recovery 
of  neutrophils, platelets and hemoglobin levels post myeloablative conditioning in all three patients 
within three months of  treatment. Enrollment is planned to be completed and the company intends 
to release additional interim results in 2021. 

In terms of  biomarker data, SGSH enzyme expression in leukocytes and CD15+ cells increased from 
undetectable levels at baseline to supra-physiological levels at three months in all three patients 
treated. Furthermore, investigators reported a reduction of  urinary GAG levels to within the normal 
range by three months in the first two patients treated with evaluable data. 

Preclinical development of  OTL-202  
OTL-202 will use the same approach as OTL-201. Lentivirus vector optimization for OTL-202 for 
treatment of  MPS-IIIB is ongoing, and we plan to continue to progress preclinical development of  
MPS-IIIB. We plan to leverage information gained from OTL-201 preclinical and clinical development 
to support the OTL-202 program. 

Research program in FTD  
Disease overview  
Frontotemporal Dementia, or FTD, is the second most common cause of  dementia after Alzheimer 
Disease in people under the age of  65. FTD is due to the atrophy of  the frontal and temporal lobes 
of  the brain. The disease manifests with progressive changes in behavior and personality, starting 
with symptoms such as decline in social and personal interactions, depression, apathy, emotional 
blunting, disinhibition and language disorders, and then progressing to general cognitive impairment 
at a later stage. In ~5% of  patients, FTD is caused by mutations in one copy (haploinsufficiency) of  
the gene that codes for progranulin, or GRN. GRN is a neurotrophic, anti-inflammatory factor that is 
produced and secreted among others by specialized cells in the brain called microglia cells. GRN 
produced by microglia cells can be taken up by neighboring neurons, helping them to be healthy 
and functional. Since GRN-FTD patients’ cells do not produce enough GRN, brain inflammation 
develops with time and neurons become progressively dysfunctional until they eventually die, leading 
to brain atrophy and the aforementioned symptoms.  

We  believe  there  are  currently  up  to  2,500  people  affected  by  GRN-FTD  in  Europe/U.S.,  with 
approximately 800 new cases per year. 

Limitations of  current therapies  
There are no treatments available for FTD and death occurs six to nine years after onset. 

Our solution, OTL-204 for treatment of  FTD 
OTL-204  is  an  ex  vivo  autologous  HSC  gene  therapy  being  developed  to  replace  the  defective 
microglia cells in the brain of  GRN-FTD patients with genetically modified microglia cells that produce 
and  secrete  a  corrective  amount  of   GRN.  These  cells  develop  naturally  from  HSCs,  which  are 
collected from the patient and modified by using a viral vector that brings a functional copy of  the 
GRN gene. When they are infused in the patient, the genetically modified HSCs naturally reach the 
brain and become resident microglia cells. OTL-204 is being developed in partnership with Professor 
Alessandra  Biffi  at  the  University  of   Padua  in  Italy.  As  part  of   the  collaboration,  we  initiated  a 
sponsored research agreement with the University of  Padua and obtained an exclusive option with 
Boston Children’s Hospital to develop and exclusively license the program.

UK STATUTORY STRATEGIC REPORT 
continued 

Preclinical development of  OTL-204 
In vitro data obtained in 2020 have demonstrated that human cell lines and mouse HSCs can be 
efficiently transduced to produce GRN. GRN is then secreted in the culture medium and can be 
taken up by other types of  cells that do not produce GRN themselves. 

Preclinical studies in a mouse model of  FTD are currently under way, and we plan to announce new 
preclinical data from this research program in the second half  of  2021. 

Research program in ALS 
Disease overview  
Amyotrophic  lateral  sclerosis,  or  ALS,  is  a  progressive  neurodegenerative  disease  of   the  motor 
neurons. People affected by ALS develop muscular weakness, twitching and atrophy that cause 
difficulties in speaking, swallowing and eventually breathing. Mutations in many different genes have 
been linked to ALS and these generally lead to the malfunctioning of  neurons and their degeneration, 
causing a strong inflammation in the brain that further worsen neuronal death. Microglia cells are a 
type of  brain cells that are heavily involved in inflammation and can contribute to neuronal loss by 
promoting oxidative stress. In particular, the Nox2 gene expressed by microglia cells induces the 
production of  reactive oxygen radical species, which cause oxidative stress, damage to molecules 
and inflammation. It is important to note that ALS patients who have lower levels of  Nox2 have a much 
better survival. 

The incidence of  ALS is currently estimated at 2.1 to 3.8 per 100,000 live births in the EU and UK 
and 1.0 to 2.6 per 100,000 live births in the U.S., for a total of  up to 12,000 to 15,000 new patients 
per year. 

Limitations of  current therapies  
There is no effective treatment for ALS and the average survival is between two and four years from 
the onset of  symptoms.  

Our solution, OTL-205 for treatment of  ALS 
OTL-205 is an ex vivo autologous gene therapy being developed to genetically modify microglia cells 
so that they have a much lower level of  Nox2 and therefore produce less oxidative stress and less 
local inflammation. Microglia cells can be derived from HSCs. In our approach, HSCs are extracted 
from the patient, modified in the laboratory with the lentiviral vector and then infused back into the 
patient.  These  modified  HSCs  then  migrate  into  the  brain,  where  they  become  microglia  cells 
replacing the diseased cells and reducing inflammation. This approach has the potential to improve 
symptoms and prolong survival in all ALS patients irrespective of  their genetic mutations. OTL-205 
is being developed in partnership with Professor Alessandra Biffi at the University of  Padua in Italy. 
As part of  the collaboration, we initiated a sponsored research agreement with the University of  
Padua and obtained an exclusive option with Boston Children’s Hospital to develop and exclusively 
license the program. 

Preclinical development of  OTL-205 
Preliminary in vitro data have shown that reducing Nox2 levels by RNA interference in microglia cells 
efficiently reduces the inflammatory response in these cells and the production of  oxygen radicals. 

We plan to continue to progress in vitro and in vivo characterization of  this therapeutic approach in 
relevant ALS mouse models.

Immunological Disorders  
Gene therapy for treatment of  WAS  
Disease overview  
WAS is a rare, life-threatening inherited disease affecting the patient’s immune system and platelets 
leading to recurrent, severe infections and uncontrollable bleeds, which are the leading causes of  
death in the disease. WAS is referred to as an “X-linked-recessive” disease as it is associated with a 
genetic defect on the X chromosome. Because it is an X-linked disease, it affects mainly males. 
Patients with WAS are born with a defect in the gene that produces the WAS protein, or WASP. As a 
result, they suffer from life-threatening thrombocytopenia and are at risk of  severe bleeds, infections, 
autoimmunity, malignancies and severe eczema. These symptoms require increasingly frequent 
hospitalizations.  The  median  survival  for  a  patient  with  WAS  without  curative  intervention  is 
approximately 15 years. Patients with early onset WAS generally have a shorter life expectancy.  

The incidence of  WAS is currently estimated at approximately 0.4 in 100,000 live male births.  

Limitations of  current therapies  
Treatment options for WAS include prophylactic anti-infective medicines, which are not always effective 
in  preventing  severe  infections  requiring  antibiotics,  antivirals,  antifungals  and  intravenous 
immunoglobulin, as well as chronic platelet transfusions to prevent severe bleeding. WAS patients are 
often prescribed chronic oral medications or topical steroids and may require admission to hospital 
for intravenous antibiotic treatment. HSCT is an alternative treatment option for some patients for whom 
a sufficiently well-matched donor is identified. Although HSCT is potentially curative in patients with 
WAS, this approach can be associated with significant risks, especially when matched cell donors 
are  not  available.  Approximately  75%  of   WAS  patients  treated  with  HSCT  experience  serious 
complications, such as severe infections requiring hospitalization, autoimmune manifestations, and 
GvHD within the first year of  receiving the treatment. The risk of  HSCT-related complications is greater 
in certain patients, including those that have had a previous splenectomy or are over five years old. 

Our solution, OTL-103 for treatment of  WAS  
We are developing OTL-103 as an ex vivo autologous HSC gene therapy to treat patients with WAS 
through a single administration. OTL-103 is manufactured from HSCs isolated from the patient’s 
peripheral blood or bone marrow that are modified to add a functional WASP gene using a lentiviral 
vector.  The  autologous  genetically  modified  cells  are  infused  back  into  the  patient  in  a  single 
intravenous infusion following treatment with a conditioning regimen that is similar to that used in an 
allogeneic HSCT.  

We obtained worldwide rights to this program through the GSK Agreement in 2018.  

OTL-103 has received orphan drug designation from the FDA and the EMA for the treatment of  WAS. 
OTL-103 has also received a Rare Pediatric Disease Designation from the FDA. RMAT designation 
was granted in 2019.  

Clinical program  
Eight patients have been treated with OTL-103 in an ongoing fresh formulation registrational trial at San 
Raffaele Hospital in Milan, Italy, and nine patients in an expanded access program, or EAP, at the same 
site, with a follow-up of  up to approximately 10 years post-treatment for the first patient treated. In 
addition, a phase 3, open-label, single arm clinical trial using the intended commercial cryopreserved 
formulation of  OTL-103 was initiated in 2019 and has recruited and treated six patients as of  January 
2020. All patients have reached a minimum of  12-months follow-up. The co-primary endpoints of  the 
study using the cryopreserved formulation include bleeding (0 to 12 months post-gene therapy) and 
infections (6 to 18 months post-gene therapy) compared with rates pre-gene therapy.

The primary goals of  the registrational clinical trial are to assess the efficacy and safety of  OTL-103 
in WAS patients, as measured by, for example, improved T-cell function, improved platelet count and 
overall survival at 36 months after treatment. Other goals of  this clinical trial include reduced bleeding 
episodes and reduced frequency of  severe infections. The primary analysis for the registrational 
clinical trial was prospectively defined to be when all patients have completed at least 3 years’ follow-
up, which was achieved in 2017. 

The first interim analysis was generated in 2017, when 6 of  the 8 subjects had completed at least 
3 years follow up. The results of  an interim analysis of  this clinical trial were published in 2019 in 
Lancet  Haematology  and  showed  that  WASP  expression  in  lymphocytes  and  platelets  was 
substantially  improved  compared  to  baseline  by  six  months  and  remain  constant  thereafter.  At 
one-year  post-treatment  with  OTL-103,  T-cell  counts  increased  in  seven  evaluable  patients,  as 
compared to counts prior to treatment, reaching normal values. Because of  the increase in T-cells, 
a reduction in infections was observed in patient’s post-treatment compared to one year prior to 
treatment with OTL-103.  

Mean platelet counts before treatment were low compared to normal, with a range of  6 x 109 to 
25 x 109 per liter observed in eight patients. Platelet counts progressively improved in all patients. 
One-year post-treatment platelet counts increased in all patients to a range of  21 x 109 to 74 x 109 
per liter, and further increases in platelet count were observed in six patients to a range of  27 x 109 
to 169 x 109 per liter at three years post-treatment. In addition to the increase in platelet count, 
increased and sustained platelet volume in seven patients was also observed at three years post-
treatment. These increases in platelet count and volume resulted in reduced frequency and severity 
of  bleeding events as compared to those experienced by these patients prior to treatment with OTL-
103. 

An EAP was put in place after the study completed enrollment. The objective of  this EAP was to 
provide treatment for patients affected by WAS with high unmet medical need in advance of  the 
product being commercially available.  

A second interim analysis of  patients in the registrational clinical trial and EAP was done in March 
2019. As reported at ASH 2019, in patients with at least one year of  follow-up in the program (n=14), 
the absence of  severe bleeding events and independence from platelet transfusions were observed 
in all subjects by 9 months of  follow-up. Additionally, a reduction in severe infection rate was observed 
at multiple time points post-treatment.

continued 

Cumulatively, as of  January 2021, a total of  23 subjects from clinical trials and an EAP have been 
treated with OTL-103. Seventeen of  the subjects – eight from clinical trials and nine from the EAP – 
have been treated with the fresh formulation of  OTL-103, and six subjects have been treated with the 
cryopreserved formulation of  OTL-103.  

From these two trials and the EAP, 18 SAEs were reported in a total of  seven subjects during the 
reporting period. Nine of  the 18 events occurred pre-gene therapy in the cryopreserved study of  
OTL-103. None of  these SAEs were considered to be related to OTL-103, no antibodies against WASP 
were detected, and no allergic reactions related to OTL-103 have been reported in subjects treated 
with OTL-103. As of  December 2020, no new safety information has changed the known safety profile 
of  OTL-103. 

Regulatory pathway for OTL-103 
An IND for OTL-103 was opened in the U.S. in 2019, and an RMAT multi-disciplinary meeting was 
held with FDA in 2020. The meeting was intended to discuss the development program completed 
to date and the path to a BLA filing in the U.S. for OTL-103. Based on feedback received during that 
meeting, we are currently working to compile the remaining data to support a BLA filing including 
additional clinical data, CMC comparability data and development of  a specific functional potency 
assay requested by the FDA.  

In 2020, we also received scientific advice from EMA to clarify the filing strategy and data required 
to file an MAA in the EU. We plan to continue engaging with the FDA and EMA in 2021 concerning 
the manufacturing and clinical development of  OTL-103.  

We plan to submit an MAA with the EMA and a BLA with the FDA for OTL-103 for the treatment of  
WAS in 2021 and 2022, respectively. 

We currently expect that our MAA and BLA submissions will be supported by a data package, 
including an adequate potency assay and clinical data from our trial with eight patients treated with 
the fresh formulation of  OTL-103 and data from the second clinical trial using the intended commercial 
cryopreserved formulation as well as data collected from nine additional patients treated with OTL-103 
under an EAP. We intend to seek approval of  OTL-103 using mobilized peripheral blood as the cellular 
source and a cryopreserved product formulation.  

Gene therapy for treatment of  ADA-SCID  
Disease overview  
Severe combined immunodeficiency, or SCID, is a rare, life-threatening inherited disease of  the 
immune system. ADA-SCID is a specific form of  SCID, commonly known as “bubble-baby disease,” 
caused by mutations in the ADA gene, resulting in a lack of, or minimal, immune system development, 
which leaves the patient vulnerable to severe and recurrent bacterial, viral and fungal infections.  

The prevalence of  ADA-SCID in the United States is currently estimated to be between one in 200,000 
and the incidence is estimated at one in 1 million live births. Higher prevalence and incidence rates 
are reported in geographies of  higher consanguinity, such as Turkey and the Middle East.  

Patients with ADA-SCID are most commonly diagnosed during the first six months of  life based on 
recurrent bacterial, fungal, and viral infections, persistent lymphopenia, and ADA activity below 1%. 
Newborn screening for T-cell deficiencies, including ADA-SCID, has now been adopted in all 50 
states in the United States, as well as in other jurisdictions, including several Canadian provinces, 
Israel, Taiwan, Germany, Switzerland, Norway and Sweden. 

38  Orchard Therapeutics plc 

 
 
UK STATUTORY STRATEGIC REPORT 
continued 

Limitations of  current therapies  
The primary treatment options for ADA-SCID are HSCT and enzyme replacement therapy, or ERT. 
Although HSCT is a potentially curative treatment for ADA-SCID patients, this procedure is associated 
with a high risk of  complications and mortality, with one-year survival rates of  43%, 67% and 86% for 
transplants from haploidentical donors, human leukocyte antigen, or HLA,-matched unrelated donors 
and HLA-matched sibling donors, respectively.  

Chronic ERT is a palliative treatment for ADA-SCID patients and involves weekly or bi-weekly intra-
muscular infusions. ERT with pegylated adenosine deaminase has been approved by the FDA and 
is commercialized in the United States. It is only available on a named patient use basis in Europe. 
Although ERT can temporarily restore immune function by maintaining high ADA levels in the plasma, 
many patients receiving chronic ERT therapy continue to have abnormally low levels of  lymphocytes 
in the blood after the first year of  treatment, and 50% of  patients therefore require supplementary 
immunoglobulin replacement therapy. Chronic ERT has been associated with a 78% survival rate at 
20 years; however, significant morbidity or mortality may occur as early as one to three years after 
the first treatment.  

Our solutions, OTL-101 and Strimvelis for treatment of  ADA-SCID  
Strimvelis is the only gammaretroviral vector mediated autologous HSC gene therapy in our portfolio. 
Each of  our other pipeline therapies, including OTL-101 for ADA-SCID and OTL-200 for MLD, employ 
a self-inactivating, or SIN, lentiviral vector-based approach that has been specifically designed to 
minimize  the  risk  of   insertional  oncogenesis  after  administration.  No  evidence  of   insertional 
oncogenesis related to lentiviral vector-based HSC gene therapy has been reported in any of  our 
programs. 

Strimvelis 
In Europe, our commercial program Strimvelis, an ex vivo gammaretrovirus mediated autologous HSC 
gene  therapy,  is  the  only  approved  gene  therapy  option  for  patients  with  ADA-SCID.  The  EMA 
approved Strimvelis in May 2016 for treatment of  children with ADA-SCID with no suitable HLA-
matched related stem cell donor. Strimvelis consists of  HSCs transduced with a gammaretroviral 
vector encoding the human adenosine deaminase cDNA sequence. Strimvelis is available at a single 
site in a fresh product formulation at San Raffaele Hospital in Milan, Italy, and has a shelf-life of  up to 
six hours.  

Summary of  the safety profile of  Strimvelis 
In October 2020, one case of  lymphoid T cell leukemia was reported in a patient approximately five 
years after such patient was treated with Strimvelis as part of  a compassionate use program. We 
notified the EMA and the relevant local European regulatory authorities of  an emerging safety issue 
and paused treating new patients with Strimvelis pending the completion of  the causality investigation. 
Subsequent  findings  confirmed  that  the  patient’s  leukemia  was  due  to  insertional  oncogenesis 
attributable to treatment with Strimvelis. The EMA’s Committee for Medicinal Products for Human Use, 
or CHMP, reviewed the updated risk-benefit assessment of  Strimvelis as part of  its ongoing MAA 
renewal procedure, concluded that the risk-benefit balance remains favorable and recommended in 
February 2021 that the marketing authorization for Strimvelis be renewed for five years, allowing 
marketing of  Strimvelis to resume.  

As of  November 2020, the safety of  Strimvelis was evaluated in 40 patients – 22 patients who were 
treated  in  the  clinical  development  program,  16  patients  treated  in  the  commercial  setting,  and 
2 patients treated with a medicinal product prepared from mobilized peripheral blood under hospital 
exemption – with a maximum follow-up of  19 years. The reported adverse reactions are in line with 
the expected safety profile of  Strimvelis and the conditioning regime administered prior to treatment 

Orchard Therapeutics plc  39

continued 

with the product. The most commonly reported adverse reaction was pyrexia. For complete safety 
details, please see the Summary of  Product Characteristics, or SmPC, for Strimvelis, available at the 
EMA website.  

OTL-101 for treatment of  ADA-SCID 
We are developing OTL-101 as an ex vivo autologous lentiviral vector-based HSC gene therapy to 
treat patients with ADA-SCID through a single administration.  

OTL-101 has been investigated in multiple clinical trials in the United States and Europe. As of  January 
2021, 67 patients have been treated with a drug product manufactured with the EFS-ADA lentiviral 
vector, with a maximum follow-up of  approximately nine years post treatment. Our program comprises 
a registrational trial conducted at University of  California Los Angeles, or UCLA, of  20 patients treated 
with a fresh product formulation of  OTL-101, supportive data derived from a clinical trial of  10 patients 
treated with a cryopreserved formulation at UCLA and additional data derived from a clinical trial of  
10 patients treated with a fresh product formulation at Great Ormond Street Hospital, or GOSH. The 
remaining 27 patients treated as of  January 2021 represent compassionate use patients or patients 
for whom we do not have adequate follow-up as of  the date of  this Annual Report but for which safety 
data is presented in the summary below. Among the 67 patients treated, four patients, including those 
treated under compassionate use and additional supportive studies, did not engraft or had to resume 
ERT and/or receive rescue bone marrow transplant. 

We obtained worldwide rights to the OTL-101 program through our UCLB/UCLA license agreement 
and we obtained worldwide rights to the Strimvelis program through our asset purchase and license 
agreement with Glaxo Group Limited and GlaxoSmithKline Intellectual Property Development LTD, 
or, together, GSK.  

OTL-101 has received orphan drug designation from the FDA and the EMA for the treatment of  
ADA-SCID and Breakthrough Therapy Designation from the FDA. OTL-101 has also received a Rare 
Pediatric Disease Designation from the FDA.  

Registrational trial conducted by UCLA (“UCLA Fresh study”) 
Production of  the fresh OTL-101 drug product formulation (with bone marrow as the cellular source) 
used in this clinical trial was performed onsite at UCLA and at the National Institutes of  Health, or 
NIH, for one patient. In this clinical trial, all 20 enrolled and treated patients were treated with ERT 
prior to enrollment and continued ERT until 30 days following their treatment with OTL-101. Two years 
follow-up was completed for all patients in August 2018. 

The primary goals of  this clinical trial were to assess the safety and efficacy of  OTL-101 in ADA-SCID 
patients,  as  measured  by  overall  survival  and  event-free  survival  at  12  months  post-treatment. 
Secondary goals in this clinical trial included immune reconstitution, as measured by lymphocyte 
and immunoglobulin levels, and reduction in severe infection rates.  

Overall survival and event-free survival of  100% was observed at 12 months post-treatment, the 
primary endpoint of  the trial. None of  the enrolled patients required rescue medication, HSCT, or 
resumption of  ERT.  

When comparing the overall survival for the OTL-101 treated patients with a historical control group 
who received allogeneic bone marrow transplant, or HSCT, between 2000 and 2016 (n=26), OTL-101 
treated patients achieved a higher overall survival rate at 24 months (100%) versus the group that 
received allogeneic bone marrow transplant (88%)  

40  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

Event-free survival is defined as survival without resumption of  PEG-ADA ERT or need for rescue 
allogeneic HSCT. Event-free survival in the OTL-101 treatment group was 100% at 24 months. In 
comparison, event-free survival in the allogeneic HSCT group was 56%.  

Importantly, patients in this trial showed immune cell reconstitution following treatment with OTL-101, 
which can lead to restoration of  both cellular and humoral immune responses. As of  the final study 
report, the severe infection rates across the full post treatment period were lower in the OTL-101 
treatment group compared with the HSCT control group. Additionally, by 24 months post-treatment, 
a considerably higher proportion of  subjects in the OTL-101 treatment group (90%) had stopped 
immunoglobulin replacement therapy compared with HSCT controls (55%). 

Supportive clinical trial with UCLA (with cryopreserved formulation) (“UCLA Cryo study”) 
A cryopreserved formulation of  OTL-101 (with bone marrow as cellular source) has been evaluated 
in a supportive clinical trial at UCLA. Enrollment for this trial is complete and of  10 patients treated, 
9 completed their final 24-month study visit as of  September 2019. One patient treated in this trial, 
who did not engraft, restarted ERT, was withdrawn from the trial, and later received a rescue HSCT. 
The  aim  of   this  clinical  trial  was  to  provide  clinical  data  supportive  of   the  analytical  chemistry, 
manufacturing, and controls, or CMC, comparison of  the fresh and cryopreserved drug product 
formulations.  As  of   February  2019,  when  7  patients  had  reached  18  months  of   follow-up,  key 
biological parameters of  engraftment and efficacy (including medians of  VCN in granulocytes and 
CD3+ T lymphocyte counts and ADA enzyme activity) were consistent when compared across the 
UCLA Fresh and UCLA Cryo studies and remained consistent throughout follow-up. 

We  believe  this  consistency  between  the  UCLA  Fresh  and  UCLA  Cryo  studies  is  supportive  of  
analytical comparability data between the fresh and cryopreserved formulations of  OTL-101.  

Additional clinical data from GOSH  
In a parallel investigator-sponsored trial conducted by GOSH, ten enrolled patients have been treated 
with fresh product formulation (with bone marrow and mobilized peripheral blood as the cellular 
source). The drug product used in this clinical trial was produced using the same vector as at UCLA, 
but with a manufacturing process with minor differences to that for OTL-101. Production of  the fresh 
formulation of  the drug product used in this clinical trial was performed onsite at GOSH. In this clinical 
trial, all patients were being treated with ERT prior to enrollment and all but one patient continued 
ERT until 30 days following initial treatment with ex vivo autologous HSC gene therapy. 

The primary goals of  this clinical trial were to assess the safety and efficacy of  the investigational 
drug product in ADA-SCID patients, as measured by overall survival and event-free survival at 12 
months  post-treatment.  Secondary  goals  in  this  clinical  trial  included  immune  reconstitution,  as 
measured by lymphocyte and immunoglobulin levels, and reduction in severe infection rates.  

As of  August 2020, overall survival of  100% has been observed at 36 months post treatment in the 
10  patients  enrolled,  and  nine  patients  have  achieved  event-free  survival,  with  only  one  patient 
resuming ERT after 12.2 months due to a failure to engraft. We believe this failure to engraft may, in 
part, be attributable to the patient’s early discontinuation of  ERT prior to treatment in contravention 
of  the trial protocol, but may also relate to other clinical factors. 

There is a second investigator-sponsored trial being conducted by GOSH, which has now enrolled 
and treated 10 patients with the cryopreserved product formulation from mobilized peripheral blood. 
The drug product used in this clinical trial is produced using the same vector and same manufacturing 
process as the drug product being evaluated at UCLA. Production of  the cryopreserved formulation 
of  the drug product used in this clinical trial is performed onsite at GOSH. In this clinical trial, all 

Orchard Therapeutics plc  41

 
UK STATUTORY STRATEGIC REPORT 
continued 

patients are being treated with ERT prior to enrollment and continue ERT until 30 days following initial 
treatment with ex vivo autologous HSC gene therapy.  

The primary goals of  this clinical trial are to assess the safety and efficacy of  the investigational drug 
product in ADA-SCID patients, as measured by overall survival and event-free survival at 12 months 
post-treatment. Secondary goals in this clinical trial include immune reconstitution, as measured by 
lymphocyte and immunoglobulin levels, and reduction in severe infection rates. As of  January 2021, 
all ten patients are alive and no longer being treated with ERT.  

OTL-101 clinical program safety  
As of  January 2021, there have been 41 SAEs reported from 16 out of  33 subjects exposed to 
OTL-101 in the EAP and UCLA Fresh and UCLA Cryo studies. Based on the safety data collected in 
the OTL-101 clinical development, expanded access and compassionate use programs, OTL-101 
has so far demonstrated a favorable safety profile.  

A global observational long-term follow-up study is now open. This study is designed to collect long 
team safety and efficacy data from ADA-SCID patients previously treated with autologous ex vivo 
gene therapy products based on the EFS-ADA lentiviral vector up to 15 years post gene therapy in 
compliance with current regulatory requirements.  

We  have  completed  final  clinical  study  reports  for  our  registrational  trial  using  OTL-101  fresh 
formulation and the second clinical trial using OTL-101 cryopreserved formulation, which we believe 
supports  the  analytical  comparability  data  between  fresh  and  cryopreserved  drug  product 
formulations.  

Gene therapy for treatment of  X-CGD  
Disease overview  
X-CGD is a rare, life-threatening inherited disease of  the immune system. X-CGD is an X-linked-
recessive disease and therefore affects males. Because of  the underlying genetic defect in the 
cytochrome B-245 beta chain, or CYBB, gene in patients with X-CGD, the patient’s white blood cells, 
specifically neutrophils/granulocytes, are unable to kill bacteria and fungi, leading to repeated chronic 
infections.  The  main  clinical  manifestations  of   X-CGD  are  pyoderma;  pneumonia;  colitis; 
lymphadenitis; brain, lung and liver abscesses; and osteomyelitis. Granuloma formation can also 
occur as a result of  persistent inflammatory response to the pathogens and can result in recurrent 
obstructions of  the gastro-intestinal and urinary tract. Patients with X-CGD typically start to develop 
infections in the first decade of  life. Mortality in X-CGD has been estimated at approximately 40% by 
the age of  35 years.  

The incidence of  X-CGD is currently estimated to be one in 200,000 male live births.  

Limitations of  current therapies  
Current treatment options for X-CGD include prophylactic antibiotics, antifungal medications and 
interferon-gamma, which are not always effective in preventing severe infections. Although HSCT is 
potentially curative in patients with X-CGD, this approach can be associated with significant risks, 
especially when well-matched cell donors are not available.  

Our solution, OTL-102 for treatment of  X-CGD  
We are developing OTL-102 as an ex vivo autologous HSC gene therapy to treat patients with X-CGD 
through a single administration. OTL-102 is manufactured from HSCs isolated from the patient’s own 
mobilized peripheral blood or bone marrow, then modified to add a functional CYBB gene using a 

42  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

lentiviral vector. The gene-modified cells are infused back into the patient in a single intravenous 
infusion following treatment with a myeloablative conditioning regimen.  

We obtained worldwide rights to the OTL-102 program through an option and license agreement with 
Généthon, pursuant to which we have exercised an option to certain intellectual property and clinical 
data associated with clinical trials at sites in the United States and the United Kingdom. 

OTL-102 has received orphan drug designation from the EMA and FDA for the treatment of  X-CGD.  

Ongoing clinical trials 
OTL-102, which has been studied in two investigator-sponsored proof  of  concept clinical trials in the 
United States and in Europe, with target enrollment of  10 patients in a clinical trial sponsored by 
UCLA in the United States and an initial target enrollment of  five patients in a clinical trial conducted 
by GOSH in Europe. The clinical trial sites included Boston Children’s Hospital, the NIH, and UCLA 
in the United States, and GOSH and The Royal Free Hospital in London. Patients enrolled in these 
trials have advanced and severe stages of  X-CGD. Manufacture of  the drug product occurred at 
each of  these sites using the same vector. As of  January 2021, nine patients had been treated in the 
clinical trial in the United States, five of  which were treated with a fresh product formulation and four 
of  which were treated with a cryopreserved formulation. Further, three patients had been treated in 
the clinical trial in Europe, and one patient was treated in a compassionate use program in Europe 
with a cryopreserved product formulation. In the future, we may treat additional pediatric patients in 
this trial with a cryopreserved formulation of  OTL-102.  

OTL-102 has shown sustained CYBB expression for over two years in six patients to date, with a 
follow-up of  three years post-treatment in patients as of  January 2021. 

In these clinical trials, the production of  NADPH-oxidase activity in neutrophils, a biomarker that 
demonstrates restored granulocyte function, has been measured in patients for up to 24 months post-
treatment. In a November 2019 publication in Nature Medicine, combined data from nine patients, 
including initial enrollees in both clinical trials and a compassionate use patient, showed NADPH-
oxidase activity, as measured by dihydrorhodamine, or DHR, assay, above 10% in six patients with at 
least 24 months follow-up. Based on the scientific literature, levels of  NADPH-oxidase activity above 
10% was a clinically meaningful percentage for fighting infections successfully. One pediatric patient 
showed initial engraftment of  DHR+ cells followed by a decrease to levels of  1% or less. The graphic 
below illustrates sustained NADPH-oxidase levels, as measured for up to 24 months post-treatment.

OTL-102 (X-CGD): NADPH-oxidase activity(1) 

(1) Excludes data from one patient treated with drug product deemed by the investigator to be a different form of  OTL-102 

drug product.  

Since September 2018, four additional patients have been treated as part of  the clinical trials, with 
one adult patient having sustained DHR+ neutrophils of  77.2% at 6 months and three pediatric 
patients displaying a similar response to the pediatric patient that did not respond to therapy. These 
observations specific to the pediatric patients were investigated and amendments to the clinical 
protocols were made in 2020 to modify the conditioning regimen used in studies with the aim of  
improving engraftment. Factors that are considered important to address are the chronic inflammatory 
environment of  the bone marrow in CGD patients, the potential for B and T cell immune responses, 
either as a result of  the disease background or as newly generated due to the ‘novel’ expression of  
gp91phox and the quality of  the drug product which may be influenced by the quality of  the collected 
cells. Investigators plan to begin enrolling additional pediatric patients (n=6) in 2021 and 2022 to 
access outcomes in the specific patient’s population. The primary goals of  this extension clinical trial 
are to assess safety and efficacy, as measured by biochemical and functional reconstitution through 
increased nicotinamide adenine dinucleotide phosphate-oxidase, or NADPH oxidase, activity in 
progeny of  engrafted cells and stability at 12 months post-treatment. Following institutional review 
board, or IRB, approvals, enrollment can commence. We intend to follow these pediatric patients in 
the proof  of  concept study and then progress OTL-102 into a registrational study. 

Two patients treated with OTL-102 as part of  the clinical trials died during the three months period 
following treatment as a result of  pre-existing disease-related complications present at the time of  
treatment with OTL-102. One of  these patients (from the UK trial) died of  acute respiratory distress 
syndrome.  This  subject  had  a  pre-existing  lung  condition.  The  other  patient  (from  the  U.S.  trial) 
developed platelet antibodies due to sensitization after several granulocyte infusions the patient 
received prior to gene therapy. The learnings from this patient resulted in a protocol amendment to 

44  Orchard Therapeutics plc 

 
 
UK STATUTORY STRATEGIC REPORT 
continued 

prevent  patients  with  existing  platelet  antibodies  from  enrolling  in  the  trial.  Neither  of   these  two 
fatalities was deemed by the investigator to be related to the therapy. A third fatality was reported 
involving a patient treated under the compassionate use program at GOSH. Because of  this patient’s 
advanced disease stage at the time of  enrollment, the patient required a surgical procedure following 
treatment and died as a result of  complications from this procedure. This fatality was deemed by the 
investigator not to be related to the product.  

Safety 
As of  March 2020, the date of  the most recent safety data available to us, patients treated in this 
clinical trial indicate OTL-102 was generally well-tolerated. There were 26 serious adverse events 
reported, one of  which was assessed by the investigator as being possibly related to OTL-102 and 
was reported as Immune Reconstitution Inflammatory Syndrome (IRIS). As of  December 2020, no 
new safety information received by us has changed the known safety profile of  OTL-102.  

Research program in NOD2-Crohn’s Disease  
Disease overview  
Crohn’s  Disease,  or  CD,  is  a  form  of   Irritable  Bowel  Disease,  or  IBD,  a  condition  affecting  the 
gastrointestinal tract caused by an uncontrolled and chronic inflammatory process directed against 
intestinal bacteria. Mutations in a number of  genes are known to confer susceptibility to the risk of  
CD,  and  amongst  these  the  NOD2  gene  (nucleotide-binding  oligomerization  domain-containing 
protein 2) is known to be the most common genetic factor, with 20-40% of  Crohn’s patients carrying 
mutations causing defective NOD2 activity. NOD2 encodes a cell receptor which controls bacterial 
elimination by innate immune cells such as macrophages through recognition of  bacterial peptide 
(MDP) and induction of  a pro-inflammatory immune response. NOD2 deficiency results in an impaired 
detection and clearance of  bacteria penetrating the gut during gastrointestinal infection, creating an 
unchecked  and  relapsing  inflammation  within  the  intestinal  tissues  characterized  by  intestinal 
granuloma formation. This leads to recurrent clinical symptoms of  chronic abdominal pain, diarrhea, 
weight loss, fatigue, malnutrition and for some patients, more severe intestinal damage requiring 
surgical resection. NOD2-CD patients typically present with more severe symptoms and are reported 
to be more refractory to existing therapies. 

The incidence of  CD is high compared to our other indications, with estimates of  100 to 200 patients 
per million in Europe and North America. Epidemiological studies suggest NOD2 genetic variants 
causing functional defects are associated with 7 to 10% of  all cases of  CD, with up to 200,000 
patients in the U.S. and Europe with two NOD2 mutated alleles. 

Limitations of  current therapies  
Current clinical management for Crohn’s disease includes use of  immune-suppressive medications, 
biological agents such as anti-TNF, steroids and surgical resection. There is currently no cure for 
Crohn’s disease, and long-term, effective treatment options are limited. Several clinical trials have 
evaluated autologous HSCT in Crohn’s disease, although with limited success. There remains a need 
for  therapeutic  modalities  that  target  underlying  causes  of   Crohn’s  disease  to  achieve  effective 
amelioration of  symptoms and disease remission. 

Our solution, OTL-104 for treatment of  NOD2-CD 
We are developing OTL-104 to evaluate its therapeutic efficacy as an ex vivo autologous HSC gene 
therapy to treat patients with NOD2-CD through a single administration. As the pathogenesis of  
NOD2-CD is associated with the function of  cells of  the hematopoietic system, ex vivo autologous 
HSC gene therapy may therefore be used restore NOD2 function to immune cells such as tissue 
resident macrophages within the gastrointestinal tract. Our OTL-104 program is being designed to 
introduce  the  NOD2  gene  into  cells  of   the  hematopoietic  system  by  lentiviral  transduction  of   a 

Orchard Therapeutics plc  45

 
UK STATUTORY STRATEGIC REPORT 
continued 

patient’s own blood or bone marrow derived HSCs, and the gene-modified cells can then be infused 
back into the patient. We own pending patent applications in the United States and other jurisdictions 
and all other intellectual property rights associated with the OTL-104 program.  

Preclinical development of  OTL-104 
OTL-104 preclinical work completed to date has shown that NOD2 defective human and NOD2 
deficient murine macrophages and monocytes are refractory to bacterial MDP stimulation. We have 
demonstrated  the  successful  restoration  of   NOD2  expression  and  functional  correction  of  
macrophage cellular responses to bacterial MDP stimulation, in NOD2 defective human cells and 
NOD2 deficient murine cells, achieved through lentiviral gene transfer of  NOD2 to human CD34+ 
HSC and murine lineage negative cells, respectively.  

We plan to continue to progress our preclinical proof  of  concept studies using an experimental mouse 
model  of   NOD2  deficiency  to  evaluate  the  use  of   gene  modified  HSC-derived  cells  to  replace 
intestinal gut resident macrophages (monocyte-derived) and to correct inflammation and colitis 
associated with NOD2-CD. We plan to announce new preclinical data from this research program in 
the second half  of  2021. 

Blood disorders 
Gene therapy for treatment of  TDT  
Disease overview  
Beta-thalassemia  is  an  inherited  blood  disorder  caused  by  one  of   over  200  mutations  in  the 
hemoglobin beta, or HBB, gene. Patients with beta-thalassemia have low levels of  hemoglobin, a 
protein in red blood cells that carries oxygen to cells throughout the body. TDT is the most severe 
form of  beta-thalassemia and requires patients to receive eight or more blood transfusions per year, 
with the number of  transfusions dependent upon the severity of  the patient’s disease. Symptoms in 
TDT patients appear within the first two years of  life and include failure to thrive, persistent infections 
and life-threatening anemia. Patients with TDT also suffer from other symptoms such as liver and 
spleen enlargement, bone deformities and osteopenia, and hypermetabolic state, resulting in chronic 
malnourishment. In the absence of  regular blood transfusions, TDT is usually fatal in infancy.  

TDT is one of  the most common genetic diseases, with a global incidence estimated at approximately 
25,000 symptomatic individuals born each year.  

Limitations of  current therapies  
The symptoms experienced by most patients with TDT are severe and often require frequent, life-
long blood transfusions to replenish the patient’s hemoglobin level. Because iron cannot be excreted 
by the body, these frequent blood transfusions can cause iron to accumulate in various organs, 
leading to risk of  heart or liver failure. Therefore, patients who receive ongoing blood transfusions 
must also receive iron chelation therapy to remove the excess iron. These medicines also have side 
effects and can negatively impact a patient’s quality of  life. Although HSCT is potentially curative in 
patients with TDT, this approach can be associated with significant risks, especially when matched 
stem cell donors are not available.  

Our solution, OTL-300 for treatment of  TDT  
OTL-300 is an ex vivo autologous HSC gene therapy, manufactured from HSCs isolated from the 
patient’s  own  mobilized  peripheral  blood,  then  modified  to  add  a  functional  HBB  gene  using  a 
lentiviral  vector.  OTL-300  is  designed  to  significantly  reduce  or  eliminate  the  need  for  blood 
transfusions in patients with TDT.

We obtained worldwide rights to this program through the GSK Agreement. OTL-300 has received 
orphan drug designation from the EMA for the treatment of  beta-thalassemia major and intermedia. 
In addition, OTL-300 has received PRIME designation from the EMA. 

In May 2020, we announced that we would be reducing our investment in the future development of  
OTL-300. 

Proof  of  concept trial (cryopreserved formulation)  
OTL-300 has been investigated in an academic-sponsored clinical trial at the San Raffaele Hospital 
in Milan, Italy to establish proof  of  concept. The study and clinical follow-up completed in November 
2019. Nine patients with severe TDT received a single intra-osseous infusion of  a cryopreserved 
formulation of  OTL-300 and were followed up for 2 years. The patients evaluated in this trial included 
six pediatric patients aged three to 17 years, and three adult patients aged 18 years and over. On 
completion of  the study, all patients enrolled in an Orchard-sponsored long-term follow-up clinical 
trial, which will continue assessments for an additional six-year period.  

The primary goals of  the clinical trial were to assess the safety and efficacy of  a cryopreserved 
formulation of  OTL-300 in TDT patients, as measured by, for example, reduction in required blood 
transfusions to manage the patients’ TDT and overall survival at 24 months post-treatment.  

All  patients  have  completed  the  24-month  study  follow-up  period.  Transfusion  independence  or 
significant  reductions  in  transfusion  frequency  and  volume  requirements  were  observed  in  six 
patients, with four of  the six pediatric patients being transfusion-free since approximately one-month 
post-treatment. Following treatment, substantial reductions (in excess of  50%) in transfusion volume 
requirements were observed over a period of  at least 3 years in two out of  three adult patients, one 
of  whom had a 9-month transfusion-free period during the first-year post-treatment. 

As of  July 2020, OTL-300 was generally well-tolerated. Six SAEs were reported in four subjects out 
of  nine patients treated, and each such SAE was assessed as not related to treatment with OTL-300. 
None  of   these  SAEs  were  fatal,  and  all  events  resolved.  As  of   December  2020,  no  new  safety 
information received has changed the safety profile of  OTL-300.  

Future applications of  our ex vivo autologous HSC gene therapy approach  
We believe that our versatile ex vivo autologous HSC gene therapy approach has the potential to 
deliver promising gene therapies to patients across a broad range of  diseases. Although our initial 
focus is on delivering our commercial and clinical-stage gene therapies to patients suffering from 
several rare diseases described above, we believe we can leverage our significant research and 
development experience and partnerships with academic institutions to identify other diseases in 
our target areas, including neurodegenerative, immunological, and blood disorders, where ex vivo 
gene  therapy  may  have  a  comparably  higher  probability  of   success  as  compared  to  other 
approaches. In 2020, we introduced new programs in larger indications and our mid- to long-term 
strategy is to leverage our HSC gene therapy approach in additional larger indications, either on our 
own  or  with  partners.  We  are  building  research  capabilities  to  continue  to  explore  additional 
indications in our laboratories.

Our regulatory strategy  
The nature of  our autologous gene therapy product candidates precludes the conduct of  Phase 1 
safety studies in healthy volunteers. Moreover, considering the indications our product candidates 
are intended to treat, which are often fatal without treatment and which are rare indications with high 
unmet  medical  need,  we  believe  our  clinical  programs  will  generally  be  eligible  to  proceed  to 
registration based on a single pivotal study given the bioethical considerations regarding the conduct 
of   randomized,  double-blind  and  placebo-controlled  clinical  trials  with  gene  therapies  for  such 
indications. Both the FDA and EMA provide expedited pathways for the development of  drug product 
candidates for the treatment of  rare diseases, particularly life-threatening diseases with high unmet 
medical need. Such drug product candidates may be eligible to proceed to registration following 
one  or  more  clinical  trials  in  a  limited  patient  population,  following  review  of   the  trial’s  design, 
endpoints and clinical data by the applicable regulatory agencies. These determinations are based 
on the applicable regulatory agency’s scientific judgement and these determinations may differ in 
the United States and the European Union.  

In some cases applicable regulatory agency may require us to perform analytical studies or conduct 
additional  clinical  trials  to  support  analytical  comparability  of   drug  product,  for  example  by 
demonstrating comparability of  drug product manufactured using HSCs derived from a patient’s 
mobilized peripheral blood and drug product manufactured using HSCs derived from a patient’s 
bone marrow and/or comparability of  drug product that has been cryopreserved and fresh drug 
product. For purposes of  this Annual Report we refer to these clinical trials as supportive clinical 
trials. In addition, certain of  our product candidates may be evaluated in clinical trials for which clinical 
data is not intended to be pooled with data from our registrational trials for purposes of  a regulatory 
submission, but will be submitted to the applicable regulatory agencies for informational purposes. 
For purposes of  this Annual Report we refer to these trials as additional clinical trials. In addition, in 
some cases patients may be ineligible for participation in our clinical trials and may receive treatment 
under a compassionate use program or an expanded access program. We expect that the available 
safety and efficacy results from all these trials would be included in any regulatory submission we 
may submit, and the applicable regulatory agency with respect to each clinical program will make a 
determination as to whether the available data is sufficient to support a regulatory submission. See 
Item 1A. Risk Factors—”The results from our clinical trials for OTL-200 for MLD, OTL-103 for WAS, 
and for any of  our other product candidates may not be sufficiently robust to support marketing 
approval or the submission of  marketing approval,” “We may be unable to demonstrate comparability 
between drug product manufactured using HSCs derived from the patient’s mobilized peripheral 
blood and drug product manufactured using HSCs derived from the patient’s bone marrow and/or 
comparability between drug product that has been cryopreserved and fresh drug product and/or 
demonstrate comparability between the manufacturing process used at academic centers with the 
manufacturing process used at CDMOs,” and “To date, most of  the clinical trials for our product 
candidates were conducted as investigator-sponsored clinical trials using drug product manufactured 
at academic sites.”

Manufacturing  
The diseases we are targeting affect patients across the world. Therefore, we are implementing our 
plans to enhance our partnerships with CDMOs and leverage technologies that will allow us to deliver 
our gene therapies globally.  

Global supply network with experienced CDMOs  
We currently partner with a network of  experienced CDMOs, including AGC Biologics S.p.A. (formerly 
MolMed S.p.A.) and Oxford BioMedica, for the supply of  our vectors and/or drug products, including 
Libmeldy. We have established relationships with commercial CDMO partners with the resources and 
capacity to meet our clinical and existing and expected initial commercial needs. Our CDMO partners 
also provide us with access to their state-of-the art manufacturing technologies.  

Manufacturing efficiencies and scalability  
We  are  investing  in  human  capital  and  advancing  manufacturing  technologies  for  HSC-based 
autologous ex vivo gene therapies. We have licensed lentiviral vector stable cell line technologies 
from GSK, completed transduction enhancer screening processes, established a vector process 
development lab at a Catapult Network facility in the UK, and are in the process of  building cell 
therapy and analytical development capabilities at our London, UK global headquarters. We seek to 
enhance our product and process understanding while actively exploring and developing innovative 
technologies for vector and drug product manufacturing to improve the efficiency and scalability of  
manufacturing processes with an ultimate goal to reliably manufacture high quality products for rare 
diseases and larger indications at lower cost. For example, we have identified and validated several 
transduction enhancing compounds in order to facilitate lentiviral vector entry into HSCs, showing a 
greater than 50% reduction in vector requirements. We continue to invest in our people to support 
the commercialization and lifecycle management of  our pipeline products.  

Cryopreservation of our gene therapy programs  
Cryopreservation of  gene-modified cells is a key component of  our strategy to deliver innovative, 
potentially  curative  gene  therapies  to  patients  worldwide.  We  have  developed  cryopreserved 
formulations  of   our  OTL-200,  OTL-103,  and  OTL-101  programs  and  expect  to  demonstrate 
comparability of  our cryopreserved formulations to earlier manufactured fresh formulations in support 
of  future submissions for marketing approval in the United States and Europe. Our programs in 
OTL-102,  OTL-300,  OTL-203  and  OTL-201  have  already  started  or  will  start  with  cryopreserved 
formulations. We plan to establish cryopreserved product formulations as the standard for all of  our 
future gene therapy candidates.  

In  the  cryopreservation  process,  a  patient’s  gene-modified  HSCs  are  frozen  at  extremely  low 
temperatures and then stored to allow quality control testing and release to be performed before 
introducing  the  gene-modified  cells  back  into  the  patient.  Our  cryopreserved  formulations  are 
expected to have shelf-lives of  months to years, enabling us to potentially distribute our products 
and product candidates from a few centralized manufacturing facilities to geographically dispersed 
treatment sites. Our ability to ultimately distribute our product candidates globally will facilitate access 
of  the therapies to patients and reduce the logistical burden on patients and their families.

Commercial operations 
Following our receipt of  full, or standard, marketing approval from the European Commission for 
Libmeldy (OTL-200) for the treatment of  early-onset MLD, we expect to launch Libmeldy in Europe 
and generate product sales as early as the first half  of  2021. In preparation for a European launch, 
we have substantially completed our build-out of  our commercial operations in Europe with a goal of  
delivering Libmeldy to patients through qualified treatment centers in the UK, France, Germany, Italy 
and  The  Netherlands.  In  addition,  we  expect  to  leverage  cross-border  and  treatment  abroad 
reimbursement pathways in both Europe and markets such as the Middle East and Turkey through 
the use of  third-party strategic partners and distributors. Subject to approval of  OTL-200 from the 
FDA, we plan to also put in place commercial operations and quality treatment centers in the U.S. 
We  have  begun  a  phased  build  of   commercial  capabilities  by  adding  employees  with  broad 
experience in quality assurance and compliance, medical education, marketing, supply chain, sales, 
public policy, patient services, market access and product reimbursement. We expect to continue 
expansion  of   these  capabilities  throughout  2021  and  beyond  as  we  continue  to  implement 
appropriate  quality  systems,  compliance  policies,  systems  and  procedures,  as  well  as  internal 
systems and infrastructure in order to support our supply chain, qualify and train additional treatment 
centers,  establish  patient-focused  programs,  educate  healthcare  professionals,  and  secure 
reimbursement. The timing and conduct of  these commercial activities will be dependent upon 
regulatory approvals and on agreements we have made or may make in the future with strategic 
collaborators.  As  part  of   the  commercialization  process,  we  are  engaged  in  discussions  with 
stakeholders across the healthcare system, including public and private payors, patient advocates 
and  organizations,  and  healthcare  providers,  to  drive  more  timely  patient  identification  through 
education, newborn screening, and diagnostic initiatives and to explore new payment models that 
we hope will enable broader patient access. We have initiated pilot studies for newborns in certain 
countries to screen for MLD and develop the necessary data package to enable universal newborn 
screening in various countries where we expect our products to be sold. Ultimately, we intend to 
utilize the commercial infrastructure that we are building to support the potential for multiple product 
launches, if  approved, sequentially across multiple geographies. For many territories and countries, 
we may also elect to utilize strategic partners, distributors, or contract field-based teams to assist in 
the commercialization of  our products. For European markets, we anticipate the list price of  Libmeldy 
to be in the range of  €2.5 to €3 million for a one-time treatment, which is less than the average 10-year 
cumulative  cost  for  some  chronic  or  lifelong  rare  disease  treatments,  such  as  certain  enzyme 
replacement therapies, which do not offer the potential for full genetic correction or a potentially 
positive impact on cognitive outcomes. We are engaging with European country- and regional-level 
payment authorities to negotiate reimbursement and access and are considering novel payment 
approaches, such as annuity payments, as part of  these negotiation discussions.  

Intellectual property and barriers to entry  
Our commercial success depends, in part, upon our ability to protect commercially important and 
proprietary aspects of  our business, defend and enforce our intellectual property rights, preserve 
the confidentiality of  our know-how and trade secrets, and operate without infringing misappropriating 
and otherwise violating valid and enforceable intellectual property rights of  others. In particular, we 
strive to protect the proprietary aspects of  our business and to develop barriers to entry that we 
believe are important to the development and commercialization of  our gene therapies. For example, 
where  appropriate,  we  develop,  or  acquire  exclusive  rights  to,  clinical  data  for  each  of   our 
products/product candidates, patents, know-how and trade secrets associated with each of  our 
products/product candidates. However, we do not own any patents or patent applications that cover 
Libmeldy, Strimvelis or any of  our lead product candidates. We in-license from UCLB and UCLA one 
family of  patents directed at OTL-101, which are issued in the U.S. and Europe We cannot guarantee 
that patents will issue from any of  existing patent applications or from any patent applications we or 

50  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

our licensors may file in the future, nor can we guarantee that any patents that may issue in the future 
from  such  patent  applications  will  be  commercially  useful  in  protecting  our  products/product 
candidates. In addition, we plan to rely on regulatory protection based on orphan drug exclusivities, 
data exclusivities and market exclusivities. See “—Government regulation” for additional information.  

We currently rely primarily on know-how and trade secret protection for aspects of  our proprietary 
technologies that we or our licensors believe are not amenable to or appropriate for patent protection, 
including, for example, clinical data and production information for Libmeldy, Strimvelis and each of  
our product candidates. However, know-how and trade secrets can be difficult to protect. Although 
we take steps to protect our know-how, trade secrets and other proprietary information, including 
restricting  access  to  our  premises  and  our  confidential  information,  as  well  as  entering  into 
agreements with our employees, consultants, advisors and potential collaborators, third parties may 
independently develop the same or similar know-how, trade secrets or proprietary information or may 
otherwise gain access to such know-how, trade secrets and other proprietary information or such 
know-how, trade secrets or other proprietary information may otherwise become known. Moreover, 
we cannot guarantee that our confidentiality agreements will provide meaningful protection or that 
they may not be breached and we may not have an adequate remedy for any such breach. As a 
result, we may be unable to meaningfully protect our know-how, trade secrets and other proprietary 
information.  

In  addition,  with  regard  to  patent  protection,  the  scope  of   coverage  being  sought  in  a  patent 
application may be reduced significantly before a patent is issued, and even after issuance the scope 
of  coverage may be challenged. As a result, we cannot guarantee that any of  our product candidates 
will be protectable or remain protected by enforceable patents. We cannot predict whether the patent 
applications we are currently pursuing will issue as patents in any particular jurisdiction or whether 
the claims of  any issued patents will provide sufficient proprietary protection from competitors. Any 
patents that we hold may be challenged, circumvented or invalidated by third parties.  

With  regards  to  our  OTL-101  product  candidate,  we  have  exclusive,  worldwide,  sublicensable, 
licenses pursuant to the UCLB/UCLA Agreement to clinical data and to a patent family containing 
one issued U.S. patent with claims directed to the OTL-101 product candidate and its use in the 
treatment of  ADA-SCID, and one issued counterpart European patent. These patents are expected 
to expire in 2036, without taking a potential patent term adjustment or extension into account. In 
addition,  under  the  UCLB/UCLA  Agreement,  we  have  non-exclusive,  worldwide,  sublicensable, 
licenses to know-how and materials relating to the OTL-101 product candidate.  

With regards to Strimvelis, OTL-103, OTL-200 and OTL-300, and as discussed in detail in “—License 
agreements”, we have exclusive, worldwide, sublicensable licenses pursuant to the GSK Agreement 
and the R&D Agreement to anonymized patient-level data arising from the clinical trials of  Strimvelis, 
OTL-103,  OTL-200  and  OTL-300  and  know-how,  including  other  clinical  data  and  production 
information relating to Strimvelis, OTL-103, OTL-200, and OTL-300.  

The term of  individual patents depends upon the legal term of  the patents in the countries in which 
they  are  obtained.  In  most  countries  in  which  we  are  seeking  patent  protection  for  our  product 
candidates,  the  patent  term  is  20  years  from  the  earliest  date  of   filing  a  non-provisional  patent 
application. In the United States, the term of  a patent may be lengthened by a patent term adjustment, 
which provides additional term caused by administrative delays at the U.S. Patent and Trademark 
Office, or USPTO, in granting a patent, or may be shortened it a patent is terminally disclaimer over 
another patent with an earlier expiration date.  

Orchard Therapeutics plc  51

 
UK STATUTORY STRATEGIC REPORT 
continued 

Furthermore, in the United States, the term of  a patent covering an FDA-approved drug may be 
eligible for a patent term extension under the Hatch-Waxman Amendments as compensation for the 
loss of  patent term during the FDA regulatory review process. The period of  extension may be up to 
five years beyond the expiration of  the patent but cannot extend the remaining term of  a patent 
beyond a total of  14 years from the date of  product approval. Only one patent among those eligible 
for an extension may be extended. Similar provisions are available in Europe and in certain other 
jurisdictions to extend the term of  a patent that covers an approved drug. In the future, if  we obtain 
any additional issued U.S. patents covering one of  our present or future product candidates, and if  
such product candidate receives FDA approval, we expect to apply for a patent term extension, if  
available, to extend the term of  the patent covering such approved product candidate. We also expect 
to seek patent term extensions in any jurisdictions where they are available, however, there is no 
guarantee  that  the  applicable  authorities,  including  the  FDA,  will  agree  with  our  assessment  of  
whether such an extension should be granted, and even if  granted, the length of  such an extension.  

License agreements  
GSK asset purchase and license agreement  
In April 2018, we entered into the GSK Agreement pursuant to which GSK transferred to us its portfolio 
of  approved and investigational rare disease gene therapies, including Strimvelis, the first gene 
therapy approved by the EMA for ADA-SCID, two late-stage clinical gene therapy programs in ongoing 
registrational trials, OTL-200 for MLD and OTL-103 for WAS; and OTL-300, a clinical-stage gene 
therapy program for TDT. In addition, GSK novated to us their R&D Agreement with Telethon-OSR.  

Under the GSK Agreement, we are subject to certain obligations to develop and advance certain of  
the acquired product candidates. For example, we are required to first use best endeavors to file an 
MAA for OTL-200 for MLD in either Europe or a BLA for MLD in the United States and to subsequently 
use commercially reasonable efforts to file an MAA or BLA, as applicable, in the other jurisdiction 
and to market, sell and promote OTL-200 in such jurisdictions. In December 2020, we received full, 
or  standard,  marketing  authorization  for  Libmeldy  in  the  European  Union  as  well  as  the  United 
Kingdom, Iceland, Liechtenstein and Norway. We are also required to use best endeavors to file a 
BLA for OTL-103 for WAS in the United States and to use commercially reasonable efforts to file an 
MAA  for  OTL-103  in  Europe,  and  to  subsequently  market,  sell  and  promote  OTL-103  in  such 
jurisdictions. We are also required to use commercially reasonable efforts to develop and file an MAA 
or BLA, as applicable, for OTL-300 for TDT in either the United States or Europe. In addition, we must 
also  use  best  endeavors  to  maintain  the  MAA  and  regulatory  designations  for  Strimvelis  in  the 
European Union and to continue to make Strimvelis available to eligible patients until an alternative 
gene therapy product has received marketing approval in Europe. We must also continue to make 
Strimvelis available at the San Raffaele Hospital for as long as a minimum number of  patients are 
treated and entitled to receive reimbursement for the provision of  Strimvelis, over a defined period. 
We intend to continue to make Strimvelis available for so long as we are required to do so under the 
GSK Agreement.  

We are required to use commercially reasonable efforts to obtain a PRV from the FDA for each of  
Strimvelis, OTL-200, OTL-103 and OTL-300 and to transfer the first such PRV to GSK. GSK also has 
an option to acquire at a defined price any PRVs granted to us thereafter for Strimvelis, OTL-200, 
OTL-103 and OTL-300. In the event that GSK does not exercise this option with respect to any PRV, 
we may sell the PRV to a third party and must share any proceeds in excess of  a specified sale price 
equally with GSK.  

52  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

Under the GSK Agreement we are also obligated to pay non-refundable royalties and milestone 
payments in relation to the gene therapy programs acquired and OTL-101. We will pay a mid-single-
digit percentage royalty on the combined annual net sales of  ADA-SCID products, which includes 
Strimvelis and our product candidate, OTL-101. We will also pay tiered royalty rates at percentages 
from the mid-teens to the low twenties for the MLD and WAS products, upon marketing approval, 
calculated  as  percentages  of   aggregate  cumulative  net  sales  of   the  MLD  and  WAS  products, 
respectively. We will pay a tiered royalty at percentages from the high single-digits to the low teens 
for the TDT product, upon marketing approval, calculated as percentages of  aggregate annual net 
sales of  the TDT product. These royalties owed to GSK are in addition to any royalties owed to other 
third parties under various license agreements for the GSK programs. In aggregate, we may pay up 
to £90.0 million in milestone payments upon achievement of  certain sales milestones. Our royalty 
obligations with respect to MLD and WAS may be deferred for a certain period in the interest of  
prioritizing available capital to develop each product. Our royalty obligations are subject to reduction 
on a product-by-product basis in the event of  market control by biosimilars and will expire in April 
2048.  

We may terminate our development and/or commercialization activities of  any of  the programs under 
the GSK Agreement, upon the occurrence of  an SAE, or if  we believe such program poses a safety 
risk to patients. GSK may require us to grant a third party a non-exclusive license under the intellectual 
property we have acquired from GSK under the GSK Agreement if  we materially breach of  our 
obligations  to  use  best  endeavors  and/or  commercially  reasonable  efforts  to  develop  and 
commercialize the acquired programs and fail to develop and implement a mutually agreeable plan 
to cure such material breach within a specified time period. The foregoing license only continues 
until such time as we cure our material breach and we must pay GSK all amounts we receive from 
the third party in connection with such license.  

Telethon-OSR research and development collaboration and license agreement  
In April 2018, in connection with our entering into the GSK Agreement, we entered into a deed of  
novation with GSK, Telethon Foundation and San Raffaele Hospital, together referred to as Telethon-
OSR, pursuant to which we acquired and assumed all of  GSK’s rights and obligations under the R&D 
Agreement with Telethon-OSR for the research, development and commercialization of  ex vivo HSC 
gene  therapies  for  ADA-SCID,  WAS,  MLD,  TDT,  and  options  on  three  additional  earlier-stage 
development programs. 

Pursuant  to  the  R&D  Agreement,  Telethon-OSR  had  granted  to  GSK  an  exclusive,  worldwide, 
sublicensable license under certain intellectual property rights to develop and commercialize ex vivo 
gene therapy products for the treatment of  ADA-SCID. In addition, Telethon-OSR had granted to GSK 
an exclusive option for an exclusive, sublicensable, worldwide license under certain intellectual 
property  rights  to  develop  and  commercialize  certain  vectors  and  gene  therapy  products  from 
disease-specific development programs for the treatment of  WAS, MLD, TDT. At the time we entered 
into  the  deed  of   novation  agreement,  GSK  had  completed  development,  launched  and 
commercialized Strimvelis for ADA-SCID in the European Union, and had exercised its exclusive 
option to obtain exclusive licenses from Telethon-OSR to the WAS, MLD and TDT programs. We 
acquired Strimvelis and GSK’s exclusive licenses relating to the ADA-SCID, WAS, MLD and TDT 
collaboration programs pursuant to the GSK Agreement and to the deed of  novation.  

Under the R&D Agreement, Telethon-OSR is required to use commercially reasonable efforts to 
conduct each of  the collaboration programs in accordance with development plans approved by a 
joint steering committee. With respect to those programs in relation to which our option has been 
exercised, we are required to use commercially reasonable efforts to develop, obtain regulatory 
approval, launch and promote in both the European Union and the United States all licensed products 

Orchard Therapeutics plc  53

 
UK STATUTORY STRATEGIC REPORT 
continued 

and  to  commercialize  and  manufacture  such  products  at  levels  sufficient  to  meet  commercial 
demands. We are required to use best efforts to renew the European Union marketing authorization 
for Strimvelis to enable patients to be treated at the San Raffaele hospital from all referring centers 
globally, as permitted by applicable law. We are responsible for the costs and activities associated 
with the continued development of  Strimvelis and each program for which an option under the R&D 
Agreement is exercised.  

As consideration for the licenses and options granted under the R&D Agreement, we are required to 
make payments to Telethon-OSR upon achievement of  certain product development milestones. We 
are obligated to pay up to an aggregate of  €31.0 million in connection with product development 
milestones  with  respect  to  those  programs  for  which  we  have  exercised  an  option  under  this 
agreement  (that  is,  our  WAS,  MLD  and  TDT  programs).  Additionally,  we  are  required  to  pay  to 
Telethon-OSR  a  tiered  mid-single  to  low-double  digit  royalty  percentage  on  net  annual  sales  of  
licensed  products  on  a  country-by-country  basis,  as  well  as  a  low  double-digit  percentage  of  
sublicense income received from any certain third party sublicensees of  the collaboration programs. 
Our royalty obligation expires on a licensed product-by-licensed product and country-by-country 
basis upon the latest to occur of  the expiration of  the last valid claim under the licensed patent rights 
in such country, the 10th anniversary of  the first commercial sale of  such licensed product in such 
country, and the expiration of  any applicable regulatory exclusivity in such country, provided that our 
royalty obligation will terminate immediately in the event significant generic or biosimilar competition 
to a licensed product achieves a certain threshold percentage of  the market share.  

Unless terminated earlier, the R&D Agreement will expire (i) on a product-by-product and country-
by-country basis upon the expiration of  all payment obligations with respect to such product in such 
country, (ii) in its entirety upon the expiration of  all payment obligations with respect to the last product 
in all countries in the world and (iii), on a program-by-program basis when no vector or gene therapy 
product is being researched, developed or commercialized. Either we or Telethon-OSR may terminate 
the R&D Agreement in its entirety or on a program-by-program basis if  the other party commits a 
material breach and fails to cure such breach within a certain period of  time. Additionally, either we 
or Telethon-OSR may terminate involvement in a collaboration program for compelling safety reasons, 
and  either  we  or  Telethon-OSR  may  terminate  the  R&D  Agreement  if   the  other  party  becomes 
insolvent. We may also terminate the R&D Agreement either in its entirety or on a program-by-program 
basis for any reason upon notice to Telethon-OSR.  

UCLB/UCLA license agreement  
In February 2016, we entered into a license agreement, or the UCLB/UCLA Agreement, with UCLB 
and UCLA, pursuant to which we obtained an exclusive, worldwide, sublicensable license to certain 
technology, clinical data, manufacturing know-how, and intellectual property rights related to the 
production of  virally transduced HSCs for treatment of  patients with ADA-SCID, in addition to certain 
other rare disease indications. We must use diligent efforts to develop and commercialize a gene 
therapy product in each of  the foregoing indications in the United States, United Kingdom and at 
least one of  France, Germany, Italy and Spain as soon as reasonably possible.  

Under the UCLB/UCLA Agreement, we are also obligated to pay UCL royalties ranging from low to 
mid-single-digit  percentages  on  net  sales  of   each  of   the  product  candidates  subject  to  the 
UCLB/UCLA  Agreement  that  receive  marketing  approval.  Our  royalty  obligations  under  the 
UCLB/UCLA Agreement terminate in February 2041. In addition, we are required to pay to UCLB 
milestone payments up to an aggregate of  £28.9 million ($37.9 million as of  December 31, 2019)

upon achievement of  our first, second and third marketing approvals of  product candidates under 
the UCLB/UCLA Agreement.  

Unless terminated earlier, the UCLB/UCLA Agreement will expire in February 2041. We may terminate 
the UCLB/UCLA Agreement in its entirety or with respect to either UCLB or UCLA for any reason 
upon prior written notice. Additionally, either we or UCLB may terminate the UCLB/UCLA Agreement 
in its entirety or on a program-by-program basis if  the other party commits a material breach and 
fails to cure such breach within a certain period of  time, or if  the other party becomes insolvent.  

Oxford BioMedica license and development agreement  
In  November  2016,  we  entered  into  a  license  and  development  agreement,  or  the  Oxford 
Development  Agreement,  with  Oxford  BioMedica  (UK)  Limited,  or  Oxford  BioMedica,  for  the 
development of  gene therapies for ADA-SCID, MPS-IIIA and certain other diseases that we may 
request be included under the Oxford Development Agreement, such other diseases referred to as 
Subsequent Indications. The Oxford Development Agreement was amended on multiple occasions 
and most recently in April 2020. 

Pursuant  to  the  Oxford  Development  Agreement,  Oxford  BioMedica  granted  us  an  exclusive, 
worldwide  license  under  certain  intellectual  property  rights  for  the  purposes  of   research, 
development and commercialization of  ex vivo gene therapy products for the treatment of  ADA-SCID, 
MPS-IIIA and Subsequent Indications, except that such license is non-exclusive to the extent the 
treatment of  a Subsequent Indication is the subject of  a certain previous license granted by Oxford 
BioMedica. Oxford BioMedica also granted us a non-exclusive, worldwide license under certain 
intellectual  property  rights  for  the  purposes  of   research,  development,  commercialization  and 
manufacture  of   ex  vivo  gene  therapy  products  for  the  treatment  of   certain  diseases  other  than 
ADA-SCID, MPS-IIIA and Subsequent Indications. Under the Oxford Development Agreement, Oxford 
BioMedica is required to use commercially reasonable efforts to perform the activities set forth in a 
collaboration plan approved by a joint steering committee, and we are responsible for certain costs 
of  the activities set forth in such collaboration plan.  

As consideration for the licenses granted under the agreement, we issued 588,220 of  our ordinary 
shares to Oxford BioMedica. We are also obligated to issue additional equity upon the achievement 
of  certain milestones, pursuant to which we issued 150,826 ordinary shares upon the achievement 
of   the  first  milestone  in  November  2017  and  150,826  ordinary  shares  were  issued  upon  the 
achievement of  further milestones in August 2018. In April 2020, the fifth milestone was deemed to 
have been met upon execution of  the amended agreement in April 2020, and the Company issued 
another 75,413 ordinary shares to Oxford BioMedica. Additionally, we are obligated to pay low single-
digit royalties on net sales of  licensed products until January 31, 2039. The foregoing royalties are 
reduced by a mid-double digit percentage in the case of  compassionate use of  a licensed product 
in a country until the first commercial sale following marketing authorization in such country. We are 
also required to pay a set monthly fee to Oxford BioMedica in the event we use a certain Oxford 
BioMedica system for generating stable cell lines.  

Unless terminated earlier, the Oxford Development Agreement will expire when no further payments 
are due to Oxford BioMedica. We may terminate the performance of  the collaboration plan upon 
notice to Oxford BioMedica, and either party may terminate the performance of  the collaboration 
plan or the Oxford Development Agreement if  the other party commits a material breach that is not 
cured  within  a  certain  period  of   time.  Either  party  may  also  terminate  the  Oxford  Development 
Agreement in the event the other party becomes insolvent.

Telethon-OSR license agreement 
In May 2019, we entered into a license agreement with Telethon-OSR under which Telethon-OSR 
granted  us  an  exclusive  worldwide  license  for  the  research,  development,  manufacture  and 
commercialization of  ex vivo autologous HSC lentiviral based gene therapy products for the treatment 
of  MPS-I, including MPS IH. Under the terms of  the agreement, Telethon-OSR is entitled to receive an 
upfront  payment,  and  we  may  be  required  to  make  milestone  payments  if   certain  development, 
regulatory and commercial milestones are achieved. Additionally, we will be required to pay Telethon-
OSR a tiered mid-single to low-double digit royalty percentage on annual net sales of licensed products. 

Competition 
The biotechnology and pharmaceutical industries are characterized by intense and rapidly changing 
competition to develop new technologies and proprietary products. While we believe that our portfolio 
of   product  candidates  and  scientific  expertise  in  gene  therapy  provides  us  with  competitive 
advantages, we face potential competition from many different sources.  

We  face  competition  not  only  from  gene  therapy  companies,  but  also  from  companies  that  are 
developing  novel,  non-gene  therapy  approaches  or  improving  existing  treatment  approaches. 
Depending on how successful these efforts are, it is possible they may increase the barriers to 
adoption and success for our product candidates, if  approved.  

We are currently aware of  the following competitive approaches among our products and clinical 
programs:  

(cid:129) MLD: To our knowledge, beyond Libmeldy in Europe, there is currently no other effective treatment 
option for patients with MLD. HSCT, for example, has demonstrated limited efficacy in halting 
disease progression and is therefore not considered a standard of  care for this disease. A number 
of  alternative approaches to HSCT are under investigation. For instance, Homology Medicines is 
at the preclinical stage of  developing an in vivo AAV gene therapy for MLD delivered intravenously, 
and Passage Bio also has a preclinical development program for MLD. We are also aware that 
Takeda  is  investigating  an  ERT  for  MLD  with  a  biweekly  intrathecal  infusion,  and  Denali 
Therapeutics is at the preclinical stage of  developing a recombinant ARSA enzyme engineered 
to cross the blood-brain barrier.  

(cid:129) MPS-I: The current standard of  care for MPS-IH patients is HSCT before the age of  30 months. 
We are aware that REGENXBIO is developing an AAV-based gene therapy, which is in Phase I 
trials and to be delivered intracisternally. bluebird bio and Immusoft have both reported that they 
are developing ex vivo cell therapies in the preclinical stage. For MPS-I patients that are not 
suitable candidates for HSCT because they lack a suitable donor, were diagnosed later in life, or 
have a less severe subtype of  MPS-I, the current standard of  care for the treatment of  MPS-I 
involves regular intravenous injections of  laronidase (Aldurazyme), an ERT commercialized by 
BioMarin  and  Sanofi  Genzyme.  A  formulation  of   laronidase  for  intrathecal  administration  is 
currently under evaluation. JCR Pharmaceuticals is developing an ERT, which is in Phase I trials.  

(cid:129) MPS-IIIA: There are currently no effective disease modifying treatment options for patients with 
MPS-IIIA. We are aware of  three gene therapy candidates in clinical development. In collaboration 
with Sarepta Therapeutics, Lysogene is developing an AAV gene therapy product administered 
through intracerebral injections; Abeona Therapeutics is developing AAV gene therapy product 
administered intravenously; and Esteve is developing an AAV gene therapy administered through 
intracerebroventricular injection. Amicus Therapeutics is at the preclinical stage of  developing 
an AAV gene therapy for MPS-IIIA. Currently we are not aware of  any companies developing ERTs 
for MPS-IIIA.

UK STATUTORY STRATEGIC REPORT 
continued 

(cid:129) WAS: The current standard of  care for WAS is HSCT. Patients who are unable to match with a 
blood donor or who are otherwise ineligible for HSCT may pursue palliative care options, including 
intravenous  immunoglobulin  and  antimicrobials  to  prevent  and  treat  infections,  topical 
corticosteroids to manage outbreaks of  eczema, platelet transfusions to treat severe bleeds, and 
immunosuppressive drugs, such as rituximab (Rituxan), to counter autoimmune manifestations. 
Splenectomy may also be used to treat thrombocytopenia. These palliative approaches do not 
slow disease progression or address the underlying cause of  WAS. In June 2020, CSL Behring 
and Seattle Children’s Research Institute announced an early-stage research collaboration to 
develop a ex vivo HSC gene therapy for WAS. We are also aware that Généthon and Boston 
Children’s Hospital are sponsoring clinical trials with ex vivo HSC gene therapy. 

(cid:129) X-CGD: Disease management options for patients with X-CGD include prophylactic antibiotics, 
antifungal medications and interferon-gamma therapy. HSCT is also a treatment option for some 
patients for whom a sufficiently well-matched donor is identified. We are not aware of  any other 
competing clinical or preclinical programs in X-CGD.  

(cid:129) ADA-SCID: The current standards of  care for the treatment of  ADA-SCID are HSCT and chronic 
ERT. In October 2018, the FDA approved elapegademase-lvlr (Revcovi), a PEGylated recombinant 
ADA ERT marketed by Leadiant Biosciences to treat ADA-SCID.  

(cid:129) TDT: The current standard of  care for the treatment of  TDT involves chronic blood transfusions 
to  address  anemia  combined  with  iron  chelation  therapy  to  manage  the  iron  overload  often 
associated  with  such  chronic  blood  transfusions.  HSCT  is  also  a  treatment  option  for  some 
patients for whom a sufficiently well-matched donor is identified. TDT is a highly competitive 
research area in gene therapy, with one ex vivo HSC gene therapy treatment already approved 
in Europe (Zynteglo) and several novel approaches under investigation, notably gene editing. 
Other  non-gene  therapy  approaches  have  been  approved  (e.g.,  Reblozyl)  or  are  under 
investigation to improve treatment outcomes in broader populations of  beta-thalassemia. Other 
programs  for  TDT  include  a  clinical  stage  ex  vivo  gene  editing  program  from  Vertex 
Pharmaceuticals and CRISPR Therapeutics, and a preclinical ex vivo gene editing program from 
Editas Medicine.  

(cid:129) GRN-FTD: There are no approved disease modifying treatments for GRN-FTD. Each of  Prevail 
Therapeutics (now owned by Eli Lilly & Company) and Passage Bio is developing in early-stage 
clinical trials an AAV gene therapy to be delivered intra-cisterna magna. Alector is developing a 
monoclonal antibody designed to increase levels of  GRN in the brain in late-stage clinical trials, 
and Denali Therapeutics is developing a modified protein designed to penetrate across the blood-
brain barrier at the preclinical stage. 

(cid:129) ALS:  There  are  currently  few  approved  treatment  options  for  ALS,  limited  to  riluzole  and 
edaravone. Multiple companies are developing gene therapies for genetically defined populations 
of  ALS. We are not aware of  any companies developing therapies targeted to reduce expression 
of  Nox2.  

(cid:129) NOD2-Crohn’s: There are no approved treatment options specifically for the NOD-2 form of  
Crohn’s disease, and many patients with Crohn’s disease have uncontrolled symptoms despite 
treatment  with  standard  of   care,  including  multiple  anti-inflammatory  biologics  and  surgical 
interventions.  We  are  not  aware  of   any  other  treatments  in  development  specifically  for  the 
NOD-2 form of  Crohn’s disease.  

Many of  our potential competitors, alone or with their strategic partners, have substantially greater 
financial, technical and other resources than we do, such as larger research and development, 

Orchard Therapeutics plc  57

 
UK STATUTORY STRATEGIC REPORT 
continued 

clinical, marketing and manufacturing organizations. Mergers and acquisitions in the biotechnology 
and pharmaceutical industries may result in even more resources being concentrated among a 
smaller  number  of   competitors.  Our  commercial  opportunity  could  be  reduced  or  eliminated  if  
competitors develop and commercialize products that are safer, more effective, have fewer or less 
severe  side  effects,  are  more  convenient  or  are  less  expensive  than  any  products  that  we  may 
develop. Competitors also may obtain FDA, EMA or other regulatory approval for their products more 
rapidly than we may obtain approval for ours, which could result in our competitors establishing a 
strong market position before we are able to enter the market. Additionally, technologies developed 
by our competitors may render our potential product candidates uneconomical or obsolete, and we 
may not be successful in marketing our product candidates against competitors.  

Government regulation  
In the United States, biological products, including gene therapy products, are subject to regulation 
under the Federal Food, Drug, and Cosmetic Act, or FD&C Act, and the Public Health Service Act, 
or PHS Act, and other federal, state, local and foreign statutes and regulations. Both the FD&C Act 
and the PHS Act and their corresponding regulations govern, among other things, the research, 
development, clinical trial, testing, manufacturing, safety, efficacy, labeling, packaging, storage, 
record  keeping,  distribution,  reporting,  advertising  and  other  promotional  practices  involving 
biological products. Each clinical trial protocol for a gene therapy product must be reviewed by the 
FDA. FDA approval must be obtained before the marketing of  biological products. 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 and we may not be able to obtain the required regulatory approvals.  

Ethical, social and legal concerns about gene therapy, genetic testing and genetic research could 
result in additional laws and regulations restricting or prohibiting the processes we may use. Federal 
and state legislatures, agencies, congressional committees and foreign governments have expressed 
interest in further regulating biotechnology. More restrictive laws and regulations or interpretations of  
existing laws or regulations, or claims that our products are unsafe or pose a hazard, could prevent 
us from commercializing any products. New government requirements may be established that could 
delay or prevent regulatory approval of  our product candidates under development. It is impossible 
to predict whether legislative changes will be enacted, regulations, policies or guidance changed, or 
interpretations by agencies or courts changed, or what the impact of  such changes, if  any, may be.  

U.S. biological products development process  
The process required by the FDA before a biological product may be marketed in the United States 
generally involves the following:  

(cid:129)

(cid:129)

(cid:129)

completion  of   nonclinical  laboratory  tests  and  animal  studies  according  to  good  laboratory 
practices, or GLPs, unless justified, and applicable requirements for the humane use of  laboratory 
animals or other applicable regulations;  

submission to the FDA of  an application for an investigational new drug application, or IND, which 
must become effective before human clinical trials may begin;  

approval of  the protocol and related documentation by an independent institutional review board, 
or IRB, or ethics committee at each clinical trial site before each study may be initiated;  

(cid:129) performance  of   adequate  and  well-controlled  human  clinical  trials  according  to  the  FDA’s 
regulations  commonly  referred  to  as  good  clinical  practices,  or  GCPs,  and  any  additional 
requirements  for  the  protection  of   human  research  subjects  and  their  health  information,  to 
establish the safety and efficacy of  the proposed biological product for its intended use;  

58  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

(cid:129)

(cid:129)

submission to the FDA of  a biologics license application, or BLA, for marketing approval that 
includes  sufficient  evidence  of   establishing  the  safety,  purity,  and  potency  of   the  proposed 
biological product for its intended indication, including from results of  nonclinical testing and 
clinical trials;  

satisfactory completion of  an FDA inspection of  the manufacturing facility or facilities where the 
biological product is produced to assess compliance with current good manufacturing practice, 
or cGMP, to assure that the facilities, methods and controls are adequate to preserve the biological 
product’s identity, strength, quality and purity and, if  applicable, the FDA’s current good tissue 
practices, or CGTPs, for the use of  human cellular and tissue products;  

(cid:129) potential FDA audit of  the nonclinical study and clinical trial sites that generated the data in 
support of  the BLA in accordance with any applicable expedited programs or designations;  

(cid:129)

review  of   the  product  candidate  by  an  FDA  advisory  committee,  where  appropriate  or  if  
applicable; 

(cid:129) payment of  user fees for FDA review of  the BLA (unless a fee waiver applies); and  

(cid:129)

FDA review and approval, or licensure, of  the BLA.  

Before testing any biological product candidate, including a gene therapy product, in humans, the 
product candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical 
studies, include laboratory evaluations of  product biological characteristics, chemistry, toxicity and 
formulation,  as  well  as  animal  studies  to  assess  the  potential  safety  and  activity  of   the  product 
candidate. The conduct of  the preclinical tests must comply with federal regulations and requirements 
including GLPs.  

An IND is an exemption from the FD&C Act that allows an unapproved product candidate to be 
shipped  in  interstate  commerce  for  use  in  an  investigational  clinical  trial  and  a  request  for  FDA 
authorization  to  administer  such  investigational  product  to  humans.  Such  authorization  must  be 
secured prior to interstate shipment and administration of  any product candidate that is not the 
subject of  an approved BLA. In support of  a request for an IND, applicants must submit a protocol 
for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as 
part of  the IND. In addition, the results of  the preclinical tests, together with manufacturing information, 
analytical data, any available clinical data or literature and plans for clinical trials, among other things, 
must be submitted to the FDA as part of  an IND. The FDA requires a 30-day waiting period after the 
filing of  each IND before clinical trials may begin. This waiting period is designed to allow the FDA 
to review the IND to determine whether human research subjects will be exposed to unreasonable 
health risks. At any time during this 30-day period the FDA may raise concerns or questions about 
the conduct of  the trials as outlined in the IND and impose a clinical hold or partial clinical hold. In 
this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials 
can begin.  

Following commencement of  a clinical trial, the FDA may also place a clinical hold or partial clinical 
hold on that trial. A clinical hold is an order issued by the FDA to the sponsor to delay a proposed 
clinical investigation or to suspend an ongoing investigation. A partial clinical hold is a delay or 
suspension of  only part of  the clinical work requested under the IND. No more than 30 days after 
imposition  of   a  clinical  hold  or  partial  clinical  hold,  the  FDA  will  provide  the  sponsor  a  written 
explanation of  the basis for the hold. Following issuance of  a clinical hold or partial clinical hold, an 
investigation may only resume after the FDA has notified the sponsor that the investigation may 
proceed.  

Orchard Therapeutics plc  59

 
UK STATUTORY STRATEGIC REPORT 
continued 

A sponsor may choose, but is not required, to conduct a foreign clinical trial under an IND. When a 
foreign clinical trial is conducted under an IND, all FDA IND requirements must be met unless waived. 
When a foreign clinical trial is not conducted under an IND, the sponsor must ensure that the study 
complies with certain regulatory requirements of  the FDA in order to use the study as support for an 
IND or application for marketing approval or licensing. In particular, such studies must be conducted 
in accordance with GCP, including review and approval by an independent ethics committee, or IEC, 
and informed consent from subjects. The FDA must be able to validate the data through an onsite 
inspection, if  deemed necessary by the FDA.  

An IRB representing each institution participating in the clinical trial must review and approve the 
plan for any clinical trial before it commences at that institution, and the IRB must conduct continuing 
review and reapprove the study at least annually. The IRB must review and approve, among other 
things, the study protocol and informed consent information to be provided to study subjects. An IRB 
must operate in compliance with FDA regulations. An IRB can suspend or terminate approval of  a 
clinical trial at its institution, or an institution it represents, if  the clinical trial is not being conducted in 
accordance  with  the  IRB’s  requirements  or  if   the  product  candidate  has  been  associated  with 
unexpected serious harm to patients.  

Some trials are overseen by an independent group of  qualified experts organized by the trial sponsor, 
known as a data safety monitoring board or committee, or DSMB. This group provides authorization 
as to whether or not a trial may move forward at designated check points based on access that only 
the group maintains to available data from the study.  

In addition to the submission of  an IND to the FDA before initiation of  a clinical trial in the United States, 
certain human clinical trials involving recombinant or synthetic nucleic acid molecules had historically 
been subject to review by the Recombinant DNA Advisory Committee, or RAC, of  the NIH, Office of  
Biotechnology  Activities,  or  the  OBA,  pursuant  to  the  NIH  Guidelines  for  Research  Involving 
Recombinant DNA Molecules, or NIH Guidelines. While the NIH Guidelines are not mandatory unless 
the research in question being conducted at or sponsored by institutions receiving NIH funding of  
recombinant or synthetic nucleic acid molecule research, many companies and other institutions not 
otherwise subject to the NIH Guidelines voluntarily follow them. On August 17, 2018, the NIH issued 
a notice in the Federal Register and issued a public statement proposing changes to the oversight 
framework for gene therapy trials, including changes to the applicable NIH Guidelines to modify the 
roles and responsibilities of  the RAC with respect to human clinical trials of  gene therapy products, 
and requesting public comment on its proposed modifications. During the public comment period, 
which closed October 16, 2018, the NIH announced that it will no longer accept new human gene 
transfer protocols for review as a part of  the protocol registration process or convene the RAC to review 
individual clinical protocols. In April 2019, NIH announced the updated guidelines, which reflect these 
proposed changes, and clarified that these trials will remain subject to the FDA’s oversight and other 
clinical trial regulations, and oversight at the local level will continue as set forth in the NIH Guidelines. 
Specifically, under the NIH Guidelines, supervision of  human gene transfer trials includes evaluation 
and assessment by an IBC, a local institutional committee that reviews and oversees research utilizing 
recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of  the 
research and identifies any potential risk to public health or the environment, and such review may 
result in some delay before initiation of  a clinical trial. Further, NIH renamed the RAC the Novel and 
Exceptional  Technology  and  Research  Advisory  Committee,  or  NExTRAC,  and  revised  its  role  to 
provide recommendations to the NIH Director and a public forum for the discussion of  the scientific, 
safety, and ethical issues associated with emerging biotechnologies.  

Information about clinical trials must be submitted within specific timeframes to the NIH for public 
dissemination on its ClinicalTrials.gov website.

UK STATUTORY STRATEGIC REPORT

Clinical trials typically are conducted in three sequential phases that may overlap or be combined:  

(cid:129) Phase 1. The biological product is initially introduced into healthy human subjects and tested for 
safety. In the case of  some products for severe or life-threatening diseases, especially when the 
product may be too inherently toxic to ethically administer to healthy volunteers, the initial human 
testing is often conducted in patients.  

(cid:129) Phase 2. The biological product is evaluated in a limited patient population to identify possible 
adverse effects and safety risks, to preliminarily evaluate the efficacy of  the product for specific 
targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.  

(cid:129) Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency, and 
safety in an expanded patient population at geographically dispersed clinical trial sites. These 
clinical trials are intended to establish the overall risk/benefit ratio of  the product and provide an 
adequate basis for approval and product labeling.  

Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after 
initial  marketing  approval.  These  clinical  trials  are  used  to  gain  additional  experience  from  the 
treatment of  patients in the intended therapeutic indication, particularly for long-term safety follow-
up. The FDA generally recommends that sponsors of  human gene therapy products integrating 
vectors such as gammaretroviral and lentiviral vectors and transposon elements observe subjects 
for potential gene therapy-related delayed adverse events for a 15-year period, including a minimum 
of  five years of  annual examinations followed by ten years of  annual queries, either in person or by 
questionnaire, of  study subjects.  

Both  the  FDA  and  the  EMA  provide  expedited  pathways  for  the  development  of   drug  product 
candidates for treatment of  rare diseases, particularly life-threatening diseases with high unmet 
medical need. Such drug product candidates may be eligible to proceed to registration following a 
single clinical trial in a limited patient population, sometimes referred to as a Phase 1/2 trial, but which 
may be deemed a pivotal or registrational trial following review of  the trial’s design and primary 
endpoints by the applicable regulatory agencies. Determination of  the requirements to be deemed 
a pivotal or registrational trial is subject to the applicable regulatory authority’s scientific judgement 
and these requirements may differ in the U.S. and the European Union.  

During all phases of  clinical development, regulatory agencies require extensive monitoring and 
auditing of  all clinical activities, clinical data, and clinical trial investigators. Annual progress reports 
detailing the results of  the clinical trials must be submitted to the FDA. Written IND safety reports 
must be promptly submitted to the FDA, the NIH and the investigators for serious and unexpected 
adverse events, any findings from other studies, tests in laboratory animals or in vitro testing that 
suggest a significant risk for human subjects, or any clinically important increase in the rate of  a 
serious suspected adverse reaction over that listed in the protocol or investigator brochure. The 
sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that 
the information qualifies for reporting. The sponsor also must notify the FDA of  any unexpected fatal 
or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial 
receipt  of   the  information.  Phase  1,  Phase  2  and  Phase  3  clinical  trials  may  not  be  completed 
successfully within any specified period, if  at all. The FDA or the sponsor, acting on its own or based 
on a recommendation from the sponsor’s data safety monitoring board may suspend a clinical trial 
at any time on various grounds, including a finding that the research subjects or patients are being 
exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of  a 
clinical trial at its institution if  the clinical trial is not being conducted in accordance with the IRB’s 
requirements or if  the biological product has been associated with unexpected serious harm to 
patients.

Human gene therapy 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 study period, the number of  patients the FDA will require to be enrolled in the studies in order 
to establish the safety, purity and potency of  human gene therapy products, or that the data generated 
in these studies will be acceptable to the FDA to support marketing approval.  

Concurrent with clinical trials, companies usually complete additional animal studies and also must 
develop additional information about the physical characteristics of  the biological product as well as 
finalize a process for manufacturing the product in commercial quantities in accordance with cGMP 
requirements. To help reduce the risk of  the introduction of  adventitious agents with use of  biological 
products, the PHS Act emphasizes the importance of  manufacturing control for products whose 
attributes cannot be precisely defined. The manufacturing process must be capable of  consistently 
producing quality batches of  the product candidate and, among other things, the sponsor must 
develop methods for testing the identity, strength, quality, potency and purity of  the final biological 
product. Additionally, appropriate packaging must be selected and tested and stability studies must 
be conducted to demonstrate that the biological product candidate does not undergo unacceptable 
deterioration over its shelf  life.  

U.S. review and approval processes  
After the completion of  clinical trials of  a biological product, FDA approval of  a BLA must be obtained 
before commercial marketing of  the biological product. The BLA must include results of  product 
development, laboratory and animal studies, human studies, information on the manufacture and 
composition of  the product, proposed labeling and other relevant information. The testing and approval 
processes require substantial time and effort and there can be no assurance that the FDA will accept 
the BLA for filing and, even if  filed, that any approval will be granted on a timely basis, if  at all.  

Within 60 days following submission of  the application, the FDA reviews a BLA submitted to determine 
if  it is substantially complete before the FDA accepts it for filing. The FDA may refuse to file any BLA 
that it deems incomplete or not properly reviewable at the time of  submission and may request 
additional information. In this event, the BLA must be resubmitted with the additional information. The 
resubmitted application also is subject to review before the FDA accepts it for filing. In most cases, 
the submission of  a BLA is subject to a substantial application user fee, although the fee may be 
waived under certain circumstances. Under the performance goals and policies implemented by the 
FDA under the Prescription Drug User Fee Act, or PDUFA, for original BLAs, the FDA targets ten 
months from the filing date in which to complete its initial review of  a standard application and 
respond to the applicant, and six months from the filing date for an application with priority review. 
The FDA does not always meet its PDUFA goal dates, and the review process is often significantly 
extended by FDA requests for additional information or clarification. This review typically takes twelve 
months from the date the BLA is submitted to the FDA because the FDA has approximately two 
months to make a “filing” decision. The review process and the PDUFA goal date may be extended 
by three months if  the FDA requests or the BLA sponsor otherwise provides additional information or 
clarification regarding information already provided in the submission within the last three months 
before the PDUFA goal date.  

Once the submission is accepted for filing, the FDA begins an in-depth substantive review of  the 
BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is 
safe,  pure  and  potent,  for  its  intended  use,  and  whether  the  product  is  being  manufactured  in 
accordance with cGMP to ensure the continued safety, purity and potency of  such product. The FDA 
may refer applications for novel biological products or biological products that present difficult or 

62  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

novel  questions  of   safety  or  efficacy  to  an  advisory  committee,  typically  a  panel  that  includes 
clinicians  and  other  experts,  for  review,  evaluation  and  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.  During  the  biological  product  approval  process,  the  FDA  also  will  determine 
whether a Risk Evaluation and Mitigation Strategy, or REMS, is necessary to assure the safe use of  
the biological product. If  the FDA concludes a REMS is needed, the sponsor of  the BLA must submit 
a proposed REMS; the FDA will not approve the BLA without a REMS, if  required.  

Before  approving  a  BLA,  the  FDA  typically  will  inspect  the  facilities  at  which  the  product  is 
manufactured. The FDA will not approve the product unless it determines that the manufacturing 
processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure 
consistent production of  the product within required specifications. For a gene therapy product, the 
FDA also will not approve the product if  the manufacturer is not in compliance with the CGTPs. These 
are FDA regulations that govern the methods used in, and the facilities and controls used for, the 
manufacture of  human cells, tissues, and cellular and tissue-based products, or HCT/Ps, which are 
human cells or tissue intended for implantation, transplant, infusion, or transfer into a human recipient. 
The primary intent of  the CGTP requirements is to ensure that cell and tissue-based products are 
manufactured  in  a  manner  designed  to  prevent  the  introduction,  transmission  and  spread  of  
communicable disease. FDA regulations also require tissue establishments to register and list their 
HCT/Ps with the FDA and, when applicable, to evaluate donors through appropriate screening and 
testing. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites 
to assure that the clinical trials were conducted in compliance with IND study requirements and GCP 
requirements. During the COVID-19 pandemic, restrictions preventing the conduct or completion of  
facility or clinical site inspections can lead to FDA deferred action on marketing applications or the 
issuance of  complete response letters. To assure cGMP, CGTP and GCP compliance, an applicant 
must incur significant expenditure of  time, money and effort in the areas of  training, record keeping, 
production and quality control.  

Under the Pediatric Research Equity Act, or PREA, a BLA or supplement to a BLA for a novel product 
(e.g.,  new  active  ingredient,  new  indication,  etc.)  must  contain  data  to  assess  the  safety  and 
effectiveness  of   the  biological  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. The FDA may grant deferrals for submission of  data or full or partial 
waivers. Unless otherwise required by regulation, PREA does not apply to any biological product for 
an indication for which orphan designation has been granted.  

Notwithstanding the submission of  relevant data and information, the FDA may ultimately decide that 
the BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from 
clinical trials are not always conclusive and the FDA may interpret data differently than we interpret 
the same data. If  the FDA decides not to approve the BLA in its present form, the FDA will issue a 
complete response letter that usually describes all of  the specific deficiencies in the BLA identified 
by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or 
major, for example, requiring additional clinical trials. Additionally, the complete response letter may 
include recommended actions that the applicant might take to place the application in a condition 
for approval. If  a complete response letter is issued, the applicant may either resubmit the BLA, 
addressing all of  the deficiencies identified in the letter, or withdraw the application.

If   a  product  receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific 
diseases  and  dosages  or  the  indications  for  use  may  otherwise  be  limited,  including  to 
subpopulations of  patients, which could restrict the commercial value of  the product. Further, the 
FDA may require that certain contraindications, warnings precautions or interactions be included in 
the  product  labeling.  The  FDA  may  impose  restrictions  and  conditions  on  product  distribution, 
prescribing, or dispensing in the form of  a REMS, or otherwise limit the scope of  any approval. In 
addition, the FDA may require post-marketing clinical trials, sometimes referred to as Phase 4 clinical 
trials, designed to further assess a biological product’s safety and effectiveness, and testing and 
surveillance programs to monitor the safety of  approved products that have been commercialized.  

Orphan drug designation  
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biological product 
intended to treat a rare disease or condition, which is generally a disease or condition that affects 
fewer  than  200,000  individuals  in  the  United  States,  or  more  than  200,000  individuals  in  the 
United States and for which there is no reasonable expectation that the cost of  developing and making 
a drug or biological product available in the United States for this type of  disease or condition will be 
recovered from sales of  the product. Orphan product designation must be requested before submitting 
a BLA. After the FDA grants orphan product designation, the identity of  the therapeutic agent and its 
potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey 
any advantage in or shorten the duration of  the regulatory review and approval process.  

Orphan  drug  designation  entitles  a  party  to  financial  incentives  such  as  opportunities  for  grant 
funding towards clinical trial costs, tax advantages and user-fee waivers. If  a product that has orphan 
designation subsequently receives the first FDA approval for the disease or condition 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 to market the same drug or biological product for the same 
indication for seven years, except in limited circumstances, such as a showing of  clinical superiority 
to  the  product  with  orphan  exclusivity.  Competitors,  however,  may  receive  approval  of   different 
products for the indication for which the orphan product has exclusivity or obtain approval for the 
same product but for a different indication for which the orphan product has exclusivity. Orphan 
product  exclusivity  also  could  block  the  approval  of   one  of   our  products  for  seven  years  if   a 
competitor obtains approval of  the same biological product for the same use or indication, and we 
are unable to demonstrate that our product is clinically superior to the previously approved drug for 
the same use or indication. If  a drug or biological product designated as an orphan product receives 
marketing approval for an indication broader than what is designated, it may not be entitled to orphan 
product exclusivity. Orphan drug status in the European Union has similar, but not identical, benefits. 

Rare Pediatric Disease Designation and Priority Review Vouchers  
Under the FD&C Act, the FDA incentivizes the development of  drugs and biological products that 
meet the definition of  a “rare pediatric disease,” defined to mean a serious or life-threatening disease 
in which the serious of  life-threatening manifestations primarily affect individuals aged from birth to 
18 years and the disease affects fewer than 200,000 individuals in the United States or affects more 
than 200,000 in the United States and for which there is no reasonable expectation that the cost of  
developing and making in the United States a drug or biological product for such disease or condition 
will be received from sales in the United States of  such drug or biological product. The sponsor of  a 
product candidate for a rare pediatric disease may be eligible for a voucher that can be used to 
obtain a priority review for a subsequent human drug or biological product application after the date 
of  approval of  the rare pediatric disease drug or biological product, referred to as a priority review 
voucher, or PRV. A sponsor may request rare pediatric disease designation from the FDA prior to the 

64  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

submission of  its BLA. A rare pediatric disease designation does not guarantee that a sponsor will 
receive a PRV upon approval of  its BLA. Moreover, a sponsor who chooses not to submit a rare 
pediatric  disease  designation  request  may  nonetheless  receive  a  PRV  upon  approval  of   their 
marketing application if  they request such a voucher in their original marketing application and meet 
all of  the eligibility criteria. If  a PRV is received, it may be sold or transferred an unlimited number of  
times. Congress has extended the PRV program through September 30, 2024, with the potential for 
PRVs to be granted through September 30, 2026. 

Expedited development and review programs  
The FDA has various programs, including Fast Track designation, breakthrough therapy designation, 
accelerated approval and priority review, that are intended to expedite or simplify the process for the 
development and FDA review of  drugs and biologics that are intended for the treatment of  serious 
or life-threatening diseases or conditions. These programs do not change the standards for approval 
but may help expedite the development or approval process. To be eligible for fast track designation, 
new drugs and biological products must be intended to treat a serious or life-threatening condition 
and  demonstrate  the  potential  to  address  unmet  medical  needs  for  the  condition.  Fast  Track 
designation applies to the combination of  the product and the specific indication for which it is being 
studied. The sponsor of  a new drug or biologic may request the FDA to designate the drug or biologic 
as a Fast Track product at any time during the clinical development of  the product. One benefit of  
fast track designation, for example, is that the FDA may consider for review sections of  the marketing 
application  for  a  product  that  has  received  Fast  Track  designation  on  a  rolling  basis  before  the 
complete application is submitted.  

Under the FDA’s breakthrough therapy program, products intended to treat a serious or life-threatening 
disease or condition may be eligible for the benefits of  the Fast Track program when preliminary clinical 
evidence demonstrates that such product may have substantial improvement on one or more clinically 
significant endpoints over existing therapies. Additionally, the FDA will seek to ensure the sponsor of  
a breakthrough therapy product receives timely advice and interactive communications to help the 
sponsor design and conduct a development program as efficiently as possible.  

Any product is eligible for priority review if  it has the potential to provide safe and effective therapy 
where  no  satisfactory  alternative  therapy  exists  or  a  significant  improvement  in  the  treatment, 
diagnosis or prevention of  a disease compared to marketed products. The FDA will attempt to direct 
additional  resources  to  the  evaluation  of   an  application  for  a  new  drug  or  biological  product 
designated for priority review in an effort to facilitate the review. Under priority review, the FDA’s goal 
is to review an application in six months once it is filed, compared to ten months for a standard review.  

Additionally, a product may be eligible for accelerated approval. Drug or biological products studied 
for their safety and effectiveness in treating serious or life-threatening illnesses and that provide 
meaningful therapeutic benefit over existing treatments may receive accelerated approval, which 
means  that  they  may  be  approved  on  the  basis  of   adequate  and  well-controlled  clinical  trials 
establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict 
a clinical benefit, or on the basis of  an effect on an intermediate clinical endpoint other than survival 
or irreversible morbidity. As a condition of  approval, the FDA may require that a sponsor of  a drug or 
biological  product  receiving  accelerated  approval  perform  adequate  and  well-controlled  post-
marketing clinical trials. In addition, the FDA currently requires as a condition for accelerated approval 
pre-approval of  promotional materials, which could adversely impact the timing of  the commercial 
launch of  the product.

RMAT designation  
As part of  the 21st Century Cures Act, enacted in December 2016, Congress amended the FD&C 
Act to facilitate an efficient development program for, and expedite review of  RMAT, which include 
cell and gene therapies, therapeutic tissue engineering products, human cell and tissue products, 
and combination products using any such therapies or products. RMAT do not include those HCT/Ps 
regulated solely under section 361 of  the PHS Act and 21 CFR Part 1271. This program is intended 
to facilitate efficient development and expedite review of  regenerative medicine therapies, which are 
intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition and qualify 
for  RMAT  designation.  A  drug  sponsor  may  request  that  FDA  designate  a  drug  as  a  RMAT 
concurrently with or at any time after submission of  an IND. FDA has 60 calendar days to determine 
whether the drug meets the criteria, including whether there is preliminary clinical evidence indicating 
that the drug has the potential to address unmet medical needs for a serious or life-threatening 
disease or condition. A BLA for a regenerative medicine therapy that has received RMAT designation 
may be eligible for priority review or accelerated approval through use of  surrogate or intermediate 
endpoints reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from 
a meaningful number of  sites. Benefits of  RMAT designation also include early interactions with FDA 
to  discuss  any  potential  surrogate  or  intermediate  endpoint  to  be  used  to  support  accelerated 
approval.  A  regenerative  medicine  therapy  with  RMAT  designation  that  is  granted  accelerated 
approval and is subject to post-approval requirements may fulfill such requirements through the 
submission of  clinical evidence from clinical trials, patient registries, or other sources of  real world 
evidence,  such  as  electronic  health  records;  the  collection  of   larger  confirmatory  data  sets;  or 
post-approval monitoring of  all patients treated with such therapy prior to its approval. Like some of  
FDA’s other expedited development programs, RMAT designation does not change the standards for 
approval but may help expedite the development or approval process.  

Post-approval requirements  
Maintaining substantial compliance with applicable federal, state, and local statutes and regulations 
requires the expenditure of  substantial time and financial resources. Rigorous and extensive FDA 
regulation of  biological products continues after approval, particularly with respect to cGMP. We 
currently rely, and may continue to rely, on third parties for the production of  clinical and commercial 
quantities of  any products that we may commercialize. Manufacturers of  our products are required 
to comply with applicable requirements in the cGMP regulations, including quality control and quality 
assurance  and  maintenance  of   records  and  documentation.  Other  post-approval  requirements 
applicable to biological products, include reporting of  cGMP deviations that may affect the identity, 
potency, purity and overall safety of  a distributed product, record-keeping requirements, reporting 
of  adverse effects, reporting updated safety and efficacy information, and complying with electronic 
record and signature requirements. After a BLA is approved, the product also may be subject to 
official lot release. 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 a summary of  the history of  manufacture of  the lot and the 
results of  all of  the manufacturer’s tests performed on the lot. The FDA also may perform certain 
confirmatory tests on lots of  some products, such as viral vaccines, 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.  

We also must comply with the FDA’s advertising and promotion requirements, such as those related 
to  direct-to-consumer  advertising,  the  prohibition  on  promoting  products  for  uses  or  in  patient 
populations that are not described in the product’s approved labeling (known as “off-label use”),

UK STATUTORY STRATEGIC REPORT 
continued 

industry-sponsored  scientific  and  educational  activities,  and  promotional  activities  involving  the 
internet. Discovery of  previously unknown problems or the failure to comply with the applicable 
regulatory requirements may result in restrictions on the marketing of  a product or withdrawal of  the 
product from the market as well as possible civil or criminal sanctions. Failure to comply with the 
applicable U.S. requirements at any time during the product development process, approval process 
or after approval, may subject an applicant or manufacturer to administrative or judicial civil or criminal 
sanctions  and  adverse  publicity.  FDA  sanctions  could  include  refusal  to  approve  pending 
applications, withdrawal of  an approval, clinical holds, warning or untitled letters, product recalls, 
product seizures, total or partial suspension of  production or distribution, injunctions, fines, refusals 
of  government contracts, mandated corrective advertising or communications with doctors or other 
stakeholders, debarment, restitution, disgorgement of  profits, or civil or criminal penalties. Any agency 
or judicial enforcement action could have a material adverse effect on us.  

Biological product manufacturers and other entities involved in the manufacture and distribution of  
approved biological products are required to register their establishments 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 laws. Accordingly, manufacturers must continue to 
expend  time,  money,  and  effort  in  the  area  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 withdrawal of  the product from the market. In 
addition, changes to the manufacturing process or facility generally require prior FDA approval before 
being  implemented  and  other  types  of   changes  to  the  approved  product,  such  as  adding  new 
indications and additional labeling claims, are also subject to further FDA review and approval.  

U.S. patent term restoration and marketing exclusivity  
Depending upon the timing, duration and specifics of  the FDA approval of  the use of  our product 
candidates, some of  our U.S. patents may be eligible for limited patent term extension under the 
Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of  
up to five years as compensation for patent term lost during product development and the FDA 
regulatory review process. However, patent term restoration cannot extend the remaining term of  a 
patent beyond a total of  14 years from the product’s approval date. The patent term restoration period 
is generally one-half  the time between the effective date of  an IND and the submission date of  a 
BLA plus the time between the submission date of  a BLA and the approval of  that application. Only 
one  patent  applicable  to  an  approved  biological  product  is  eligible  for  the  extension  and  the 
application for the extension must be submitted prior to the expiration of  the patent. In addition, a 
patent can only be extended once and only for a single product. The USPTO, in consultation with the 
FDA, reviews and approves the application for any patent term extension or restoration. In the future, 
we may intend to apply for restoration of  patent term for one of  our patents, if  and as applicable, to 
add patent life beyond its current expiration date, depending on the expected length of  the clinical 
trials and other factors involved in the filing of  the relevant BLA.  

A biological product can obtain pediatric market exclusivity in the United States. Pediatric exclusivity, 
if  granted, adds six months to existing exclusivity periods, including some regulatory exclusivity 
periods tied to patent terms. This six-month exclusivity, which runs from the end of  other exclusivity 
protection or patent term, may be granted based on the voluntary completion of  a pediatric study in 
accordance with an FDA-issued “Written Request” for such a study.  

The  ACA,  signed  into  law  on  March  23,  2010,  includes  a  subtitle  called  the  Biologics  Price 
Competition and Innovation Act of  2009 which created an abbreviated approval pathway for biological 

Orchard Therapeutics plc  67

 
UK STATUTORY STRATEGIC REPORT 
continued 

products  shown  to  be  similar  to,  or  interchangeable  with,  an  FDA-licensed  reference  biological 
product. This amendment to the PHS Act attempts to minimize duplicative testing. Biosimilarity, which 
requires that there be no clinically meaningful differences between the biological product and the 
reference product in terms of  safety, purity, and potency, can be shown through analytical studies, 
animal studies, and a clinical trial or trials. Interchangeability requires that a product is biosimilar to 
the reference product and the product must demonstrate 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.  

A reference biological product is granted four- and 12-year exclusivity periods from the time of  first 
licensure of  the product. FDA will not accept  an  application  for  a biosimilar  or  interchangeable 
product based on the reference biological product until four years after the date of  first licensure of  
the reference product, and FDA will not approve an application for a biosimilar or interchangeable 
product based on the reference biological product until twelve years after the date of  first licensure 
of  the reference product. “First licensure” typically means the initial date the particular product at 
issue was licensed in the United States. Date of  first licensure does not include the date of  licensure 
of  (and a new period of  exclusivity is not available for) a biological product if  the licensure is for a 
supplement  for  the  biological  product  or  for  a  subsequent  application  by  the  same  sponsor  or 
manufacturer of  the biological product (or licensor, predecessor in interest, or other related entity) 
for a change (not including a modification to the structure of  the biological product) that results in a 
new indication, route of  administration, dosing schedule, dosage form, delivery system, delivery 
device or strength, or for a modification to the structure of  the biological product that does not result 
in a change in safety, purity, or potency. Therefore, one must determine whether a new product 
includes a modification to the structure of  a previously licensed product that results in a change in 
safety, purity, or potency to assess whether the licensure of  the new product is a first licensure that 
triggers  its  own  period  of   exclusivity.  Whether  a  subsequent  application,  if   approved,  warrants 
exclusivity as the “first licensure” of  a biological product is determined on a case-by-case basis with 
data submitted by the sponsor.  

Additional regulation  
In addition to the foregoing, state and federal laws regarding environmental protection and hazardous 
substances, including the Occupational Safety and Health Act, the Resource Conservancy and 
Recovery Act and the Toxic Substances Control Act, affect our business. These and other laws govern 
our use, handling and disposal of  various biological, chemical and radioactive substances used in, 
and wastes generated by, our operations. If  our operations result in contamination of  the environment 
or expose individuals to hazardous substances, we could be liable for damages and governmental 
fines. We believe that we are in material compliance with applicable environmental laws and that 
continued compliance therewith will not have a material adverse effect on our business. We cannot 
predict, however, how changes in these laws may affect our future operations.

U.S. Foreign Corrupt Practices Act  
The  U.S.  Foreign  Corrupt  Practices  Act,  to  which  we  are  subject,  prohibits  corporations  and 
individuals from engaging in certain activities to obtain or retain business or to influence a person 
working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of  anything of  
value  to  any  foreign  government  official,  government  staff   member,  political  party  or  political 
candidate in an attempt to obtain or retain business or to otherwise influence a person working in an 
official capacity.  

Government regulation outside of the United States  
In addition to regulations in the United States, we are subject to a variety of  regulations in other 
jurisdictions  governing,  among  other  things,  research  and  development,  clinical  trials,  testing, 
manufacturing, safety, efficacy, labeling, packaging, storage, record keeping, distribution, reporting, 
advertising and other promotional practices involving biological products as well as authorization 
and approval of  our products. Because biologically sourced raw materials are subject to unique 
contamination risks, their use may be restricted in some countries.  

The requirements and process governing the conduct of  clinical trials, product licensing, pricing and 
reimbursement vary from country to country. In all cases, the clinical trials must be conducted in 
accordance with GCP and the applicable regulatory requirements and the ethical principles that 
have their origin in the Declaration of  Helsinki. If  we fail to comply with applicable foreign regulatory 
requirements,  we  may  be  subject  to,  among  other  things,  fines,  suspension  of   clinical  trials, 
suspension or withdrawal of  regulatory approvals, product recalls, seizure of  products, operating 
restrictions and criminal prosecution. 

European Union clinical trials regulation 
Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from 
regulatory authorities in foreign countries prior to the commencement of  clinical trials or marketing of  
the product in those countries. Certain countries outside of  the United States have a similar process 
that requires the submission of  a clinical trial application much like the IND prior to the commencement 
of  human clinical trials. In the European Union, for example, a CTA must be submitted for each clinical 
trial to each country’s National Competent Authority, or NCA, and at least one independent Ethics 
Committee,  or  EC,  much  like  the  FDA  and  an  IRB,  respectively.  Once  the  CTA  is  approved  in 
accordance with a country’s requirements, the corresponding clinical trial may proceed. Under the 
current  regime  (the  EU  Clinical  Trials  Directive  2001/20/EC  and  corresponding  national  laws)  all 
suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical 
trial have to be reported to the NCA and ECs of  the Member State where they occurred. 

In April 2014, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which 
is set to replace the current Clinical Trials Directive 2001/20/EC. It will overhaul the current system of  
approvals for clinical trials in the European Union. Specifically, the new regulation, which will be 
directly applicable in all Member States (meaning that no national implementing legislation in each 
European Union Member State is required), aims at simplifying and streamlining the approval of  
clinical trials in the European Union. For instance, the new Clinical Trials Regulation provides for a 
streamlined application procedure via a single entry point and strictly defined deadlines for the 
assessment of  clinical trial applications. It is expected that the new Clinical Trials Regulation (EU) No 
536/2014  will  come  into  effect  following  confirmation  of   full  functionality  of   the  Clinical  Trials 
Information System, the centralized European Union portal and database for clinical trials foreseen 
by the new Clinical Trials regulation, through an independent audit, which is currently expected to 
occur in December 2021.

Drug review and approval in the EEA 
In the European Economic Area (comprised of  the European Union Member States plus Norway, 
Iceland  and  Liechtenstein),  or  EEA,  medicinal  products,  including  advanced  therapy  medicinal 
products, or ATMPs, are subject to extensive pre- and post-market regulation by regulatory authorities 
at both the EEA and national levels. ATMPs comprise gene therapy products, somatic cell therapy 
products and tissue engineered products. Gene therapy products deliver genes into the body that 
lead to a therapeutic, prophylactic or diagnostic effect. Libmeldy is authorized as a gene therapy 
product in the EEA, and we anticipate that our gene therapy development products would also be 
regulated as ATMPs in the EEA.  

To obtain regulatory approval of  an ATMP under EEA regulatory systems, we must submit an MAA 
under the centralized procedure administered by the EMA. The application used to submit the BLA 
in the United States is similar to that required in the European Union, with the exception of, among 
other  things,  certain  specific  requirements  set  out  in  the  ATMP  Regulation,  for  example  certain 
particulars to be contained in the summary of  product characteristics. The centralized procedure 
provides for the grant of  a single marketing authorization by the European Commission that is valid 
across all of  the EEA. As provided for in the ATMP Regulation, the scientific evaluation of  MAAs for 
ATMPs  is  primarily  performed  by  a  specialized  scientific  committee  called  the  Committee  for 
Advanced Therapies, or CAT. The CAT prepares a draft opinion on the quality, safety and efficacy of  
the ATMP which is the subject of  the MAA, which is sent for final approval to the Committee for 
Medicinal  Products  for  Human  Use,  or  CHMP.  The  CHMP  recommendation  is  then  sent  to  the 
European Commission, which adopts a decision binding in all EEA Member States. The maximum 
timeframe for the evaluation of  a MAA for an ATMP is 210 days from receipt of  a valid MAA, excluding 
clock  stops  when  additional  information  or  written  or  oral  explanation  is  to  be  provided  by  the 
applicant in response to questions of  the CAT and/or CHMP. Clock stops may extend the timeframe 
of  evaluation of  a MAA considerably beyond 210 days. Where the CHMP gives a positive opinion, 
the EMA provides the opinion together with supporting documentation to the European Commission, 
who make the final decision to grant a marketing authorization, which is issued within 67 days of  
receipt of  the EMA’s recommendation. Accelerated assessment may be granted by the CHMP in 
exceptional cases, when a medicinal product is of  major interest from the point of  view of  public 
health and, in particular, from the viewpoint of  therapeutic innovation. If  the CHMP accepts such a 
request, the timeframe of  210 days for assessment will be reduced to 150 days (excluding clock 
stops), but it is possible that the CHMP may revert to the standard time limit for the centralized 
procedure if  it determines that the application is no longer appropriate to conduct an accelerated 
assessment. 

Now that the UK (which comprises Great Britain and Northern Ireland) has left the European Union, 
Great Britain will no longer be covered by centralized marketing authorizations (under the Northern 
Irish Protocol, centralized marketing authorizations will continue to be recognized in Northern Ireland). 
All  medicinal  products  with  a  current  centralized  marketing  authorization  were  automatically 
converted to Great Britain marketing authorizations on January, 1 2021. For a period of  two years 
from January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or MHRA, the UK 
medicines regulator, may rely on a decision taken by the European Commission on the approval of  
a new marketing authorization in the centralized procedure, in order  to more quickly grant a new 
Great Britain marketing authorization. A separate application will, however, still be required.

Data and marketing exclusivity 
The EEA also provides opportunities for market exclusivity. Upon receiving marketing authorization 
in the EEA, innovative medicinal products generally receive eight years of  data exclusivity and an 
additional two years of  market exclusivity. If  granted, data exclusivity prevents generic or biosimilar 
applicants from referencing the innovator’s preclinical and clinical trial data contained in the dossier 
of  the reference product when applying for a generic or biosimilar marketing authorization during a 
period of  eight years from the date on which the reference product was first authorized in the EEA. 
During  the  additional  two-year  period  of   market  exclusivity,  a  generic  or  biosimilar  marketing 
authorization  can  be  submitted,  and  the  innovator’s  data  may  be  referenced,  but  no  generic  or 
biosimilar product can be marketed until the expiration of  the market exclusivity period. The overall 
ten-year period will be extended to a maximum of  eleven years if, during the first eight years of  those 
ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic 
indications which, during the scientific evaluation prior to authorization, is held to bring a significant 
clinical benefit in comparison with existing therapies. Even if  an innovative medicinal product gains 
the prescribed period of  data exclusivity, another company may market another version of  the product 
if  such company obtained marketing authorization based on a MAA with a complete independent 
data package of  pharmaceutical tests, preclinical tests and clinical trials. There is, however, no 
guarantee that a product will be considered by the European Union’s regulatory authorities to be an 
innovative medicinal product, and products may therefore not qualify for data exclusivity.  

Orphan drug designation and exclusivity 
Products with an orphan designation in the EEA can receive ten years of  market exclusivity, during 
which time “no similar medicinal product” for the same indication may be placed on the market. A 
“similar medicinal product” is defined as a medicinal product containing a similar active substance 
or substances as contained in an authorized orphan medicinal product, and which is intended for 
the same therapeutic indication. An orphan product can also obtain an additional two years of  market 
exclusivity in the EEA where an agreed Pediatric Investigation Plan for pediatric studies has been 
complied with. No extension to any supplementary protection certificate can be granted on the basis 
of  pediatric studies for orphan indications.  

The criteria for designating an “orphan medicinal product” in the EEA are similar in principle to those 
in the United States. Under Article 3 of  Regulation (EC) 141/2000, a medicinal product may be 
designated as an orphan medicinal product if  it meets the following criteria: (1) it is intended for the 
diagnosis, prevention or treatment of  a life-threatening or chronically debilitating condition; and (2) 
either the prevalence of  such condition must not be more than five in 10,000 persons in the EEA 
when the application is made, or without the benefits derived from orphan status, it must be unlikely 
that the marketing of  the medicine would generate sufficient return in the EEA to justify the investment 
needed for its development; and (3) there exists no satisfactory method of  diagnosis, prevention or 
treatment of  such condition authorized for marketing in the EEA, or if  such a method exists, the 
product will be of  significant benefit to those affected by the condition, as defined in Regulation (EC) 
847/2000. Orphan medicinal products are eligible for financial incentives such as reduction of  fees 
or fee waivers and are, upon grant of  a marketing authorization, entitled to ten years of  market 
exclusivity for the approved therapeutic indication. The application for orphan drug designation must 
be submitted before the application for marketing authorization. The applicant will receive a fee 
reduction for the MAA if  the orphan drug designation has been granted, but not if  the designation is 
still pending at the time the marketing authorization is submitted. Orphan drug designation does not 
convey any advantage in, or shorten the duration of, the regulatory review and approval process.

UK STATUTORY STRATEGIC REPORT 
continued 

The  10-year  market  exclusivity  may  be  reduced  to  six  years  if,  at  the  end  of   the  fifth  year,  it  is 
established that the product no longer meets the criteria for orphan designation, for example, if  the 
product is sufficiently profitable not to justify maintenance of  market exclusivity. Otherwise, orphan 
medicine marketing exclusivity may be revoked only in very select cases, such as if:  

(cid:129)

(cid:129)

(cid:129)

a second applicant can establish that its product, although similar, is safer, more effective or 
otherwise clinically superior;  

the marketing authorization holder consents to a second orphan medicinal product application; 
or  

the marketing authorization holder cannot supply enough orphan medicinal product.  

Pediatric development  
In the EEA, companies developing a new medicinal product must agree upon a Pediatric Investigation 
Plan, or PIP, with the EMA’s Pediatric Committee, or PDCO, and must conduct pediatric clinical trials 
in accordance with that PIP, unless a waiver applies, (e.g., because the relevant disease or condition 
occurs only in adults). The PIP sets out the timing and measures proposed to generate data to 
support a pediatric indication of  the drug for which marketing authorization is being sought. The 
marketing authorization application for the product must include the results of  pediatric clinical trials 
conducted in accordance with the PIP, unless a waiver applies, or a deferral has been granted by 
the PDCO of  the obligation to implement some or all of  the measures of  the PIP until there are 
sufficient data to demonstrate the efficacy and safety of  the product in adults, in which case the 
pediatric clinical trials must be completed at a later date. Products that are granted a marketing 
authorization with the results of  the pediatric clinical trials conducted in accordance with the PIP are 
eligible for a six month extension of  the protection under a supplementary protection certificate (if  
any is in effect at the time of  approval) even where the trial results are negative. In the case of  orphan 
medicinal products, a two year extension of  the orphan market exclusivity may be available. This 
pediatric reward is subject to specific conditions and is not automatically available when data in 
compliance with the PIP are developed and submitted.  

PRIME Designation  
In March 2016, the EMA launched an initiative to facilitate development of  product candidates in 
indications, often rare, for which few or no therapies currently exist. The PRIority MEdicines, or PRIME, 
scheme is intended to encourage drug development in areas of  unmet medical need and provides 
accelerated  assessment  of   products  representing  substantial  innovation,  where  the  marketing 
authorization application will be made through the centralized procedure. Eligible products must 
target conditions for which where is an unmet medical need (there is no satisfactory method of  
diagnosis, prevention or treatment in the EEA or, if  there is, the new medicine will bring a major 
therapeutic advantage) and they must demonstrate the potential to address the unmet medical need 
by introducing new methods of  therapy or improving existing ones. Products from small- and medium-
sized enterprises may qualify for earlier entry into the PRIME scheme than larger companies. Many 
benefits accrue to sponsors of  product candidates with PRIME designation, including but not limited 
to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs 
and other development program elements, and accelerated marketing authorization application 
assessment  once  a  dossier  has  been  submitted.  Importantly,  a  dedicated  Agency  contact  and 
rapporteur  from  the  CHMP  or  CAT  are  appointed  early  in  PRIME  scheme  facilitating  increased 
understanding  of   the  product  at  EMA’s  Committee  level.  A  kick-off   meeting  initiates  these 
relationships and includes a team of  multidisciplinary experts at the EMA to provide guidance on 
the overall development and regulatory strategies. Where, during the course of  development, a 
medicine no longer meets the eligibility criteria, support under the PRIME scheme may be withdrawn.

Post-approval controls  
Following approval, the holder of  the marketing authorization is required to comply with a range of  
requirements  applicable  to  the  manufacturing,  marketing,  promotion  and  sale  of   the  medicinal 
product. These include the following: 

(cid:129)

The holder of  a marketing authorization must establish and maintain a pharmacovigilance system 
and appoint an individual qualified person for pharmacovigilance, who is responsible for oversight 
of   that  system.  Key  obligations  include  expedited  reporting  of   suspected  serious  adverse 
reactions and submission of  periodic safety update reports, or PSURs.  

(cid:129) All new MAAs must include a risk management plan, or RMP, describing the risk management 
system that the company will put in place and documenting measures to prevent or minimize the 
risks associated with the product. The regulatory authorities may also impose specific obligations 
as  a  condition  of   the  marketing  authorization.  Such  risk-minimization  measures  or  post-
authorization obligations may include additional safety monitoring, more frequent submission of  
PSURs, or the conduct of  additional clinical trials or post-authorization safety studies. RMPs and 
PSURs are routinely available to third parties requesting access, subject to limited redactions.  

(cid:129) All advertising and promotional activities for the product must be consistent with the approved 
SmPC  and  therefore  all  off-label  promotion  is  prohibited.  Direct-to-consumer  advertising  of  
prescription medicines is also prohibited in the European Union. Although general requirements 
for advertising and promotion of  medicinal products are established under European Union 
directives, the details are governed by regulations in each European Union Member State and 
can differ from one country to another.  

Brexit and the Regulatory Framework in the United Kingdom  
In June 2016, the electorate in the United Kingdom voted in favor of  leaving the European Union 
(commonly  referred  to  as  “Brexit”).  Thereafter,  in  March  2017,  the  country  formally  notified  the 
European  Union  of   its  intention  to  withdraw  pursuant  to  Article  50  of   the  Lisbon  Treaty.  The 
United Kingdom formally left the European Union on January 31, 2020. A transition period began on 
February 1, 2020, during which European Union pharmaceutical law remained applicable to the 
United Kingdom. This transition period ended on December 31, 2020. Since the regulatory framework 
in the United Kingdom covering quality, safety and efficacy of  pharmaceutical products, clinical trials, 
marketing authorization, commercial sales and distribution of  pharmaceutical products is derived 
from European Union Directives and Regulations, Brexit could materially impact the future regulatory 
regime which applies to products and the approval of  product candidates in the United Kingdom as 
United Kingdom legislation now has the potential to diverge from European Union legislation. It 
remains  to  be  seen  how  Brexit  will  impact  regulatory  requirements  for  product  candidates  and 
products in the United Kingdom in the long-term. The MHRA, the United Kingdom medicines and 
medical devices regulator, has recently published detailed guidance for industry and organizations 
to follow from January 1, 2021 now that the transition period is over, which will be updated as the 
United Kingdom’s regulatory position on medicinal products evolves over time. Brexit has also created 
uncertainty with regard to data protection regulation in the United Kingdom, and in particular, how 
data transfers from the European Union to the United Kingdom will be regulated. The European Union 
and the United Kingdom have agreed a bridging period of  up to 6 months to allow the continued 
free flow of  data from the European Union to the United Kingdom, during which time the European 
Commission will assess whether the United Kingdom will be granted adequacy status. There is no 
certainty that an adequacy decision will be granted. If  it is not, legal uncertainties regarding the flow 
of  data across borders could increase the complexity and cost of  transferring personal data from 
the European Union to the United Kingdom.

Other healthcare laws and compliance requirements  
In the United States, our current and future operations are subject to regulation by various federal, 
state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare 
and  Medicaid  Services,  or  CMS,  other  divisions  of   the  U.S.  Department  of   Health  and  Human 
Services, or HHS (such as the Office of  Inspector General, Office for Civil Rights and the Health 
Resources and Service Administration), the U.S. Department of  Justice, or DOJ, and individual U.S. 
Attorney offices within the DOJ, and state and local governments. For example, our clinical research, 
sales, marketing and scientific/educational grant programs may have to comply with the anti-fraud 
and abuse provisions of  the Social Security Act, the false claims laws, the privacy and security 
provisions of  the federal Health Insurance Portability and Accountability Act of  1996, or HIPAA, and 
similar state laws, each as amended, as applicable: 

(cid:129)

(cid:129)

(cid:129)

the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully 
soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), 
directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the 
referral of  an individual, or the purchase, lease, order, arrangement or recommendation of  any 
good, facility, item or service for which payment may be made, in whole or in part, under a federal 
healthcare program, such as the Medicare and Medicaid programs; a person or entity does not 
need to have actual knowledge of  the federal Anti-Kickback Statute or specific intent to violate it 
to have committed a violation. In addition, the government may assert that a claim including items 
or services resulting from a violation of  the federal Anti-Kickback Statute constitutes a false or 
fraudulent claim for purposes of  the federal False Claims Act or federal civil money penalties 
statute;  

the federal civil and criminal false claims laws and civil monetary penalty laws, including the False 
Claims Act, which prohibit, among other things, individuals or entities from knowingly presenting, 
or causing to be presented, false or fraudulent claims for payment to, or approval by Medicare, 
Medicaid, or other federal healthcare programs, knowingly making, using or causing to be made 
or used a false record or statement material to a false or fraudulent claim or an obligation to pay 
or  transmit  money  to  the  federal  government,  or  knowingly  concealing  or  knowingly  and 
improperly  avoiding  or  decreasing  or  concealing  an  obligation  to  pay  money  to  the  federal 
government. Manufacturers can be held liable under the False Claims Act even when they do 
not submit claims directly to government payers if  they are deemed to “cause” the submission 
of  false or fraudulent claims. The False Claims Act also permits a private individual acting as a 
“whistleblower” to bring actions on behalf  of  the federal government alleging violations of  the 
False Claims Act and to share in any monetary recovery;  

the  anti-inducement  law,  which  prohibits,  among  other  things,  the  offering  or  giving  of  
remuneration, which includes, without limitation, any transfer of  items or services for free or for 
less than fair market value (with limited exceptions), to a Medicare or Medicaid beneficiary that 
the person knows or should know is likely to influence the beneficiary’s selection of  a particular 
supplier of  items or services reimbursable by a federal or state governmental program;  

(cid:129) HIPAA, which created new federal criminal statutes that prohibit knowingly and willfully executing, 
or attempting to execute, a scheme to defraud any healthcare benefit program or 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  the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering 
up by any trick or device a material fact or making any materially false, fictitious, or fraudulent 
statements  or  representations  in  connection  with  the  delivery  of,  or  payment  for,  healthcare 
benefits, items or services relating to healthcare matters; similar to the federal Anti-Kickback 
Statute, a person or entity does not need to have actual knowledge of  the statute or specific intent 
to violate it in order to have committed a violation;

UK STATUTORY STRATEGIC REPORT 
continued 

(cid:129) HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act 
of  2009, and their respective implementing regulations, which impose requirements on certain 
covered  healthcare  providers,  health  plans,  and  healthcare  clearinghouses  as  well  as  their 
respective business associates that perform services for them that involve the use, or disclosure 
of, individually identifiable health information, relating to the privacy, security and transmission of  
individually identifiable health information;  

(cid:129)

(cid:129)

(cid:129)

the federal transparency requirements under the ACA, including the provision commonly referred 
to as the Physician Payments Sunshine Act, and its implementing regulations, which requires 
applicable manufacturers of  drugs, devices, biologics and medical supplies for which payment 
is available under Medicare, Medicaid or the Children’s Health Insurance Program to report 
annually to the U.S. Department of  Health and Human Services, CMS, information related to 
payments or other transfers of  value made to physicians (defined to include doctors, dentists, 
optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and 
investment interests held by the physicians described above and their immediate family members. 
Effective January 1, 2022, these reporting obligations will extend to include transfers of  value 
made to certain non-physician providers such as physician assistants and nurse practitioners;  

federal government price reporting laws, which require us to calculate and report complex pricing 
metrics in an accurate and timely manner to government programs; and  

federal consumer protection and unfair competition laws, which broadly regulate marketplace 
activities and activities that potentially harm consumers.  

In addition to the above, on November 20, 2020, the Office of  Inspector General, or OIG, finalized 
further modifications to the federal Anti-Kickback Statute. Under the final rules, OIG added safe harbor 
protections  under  the  Anti-Kickback  Statute  for  certain  coordinated  care  and  value-based 
arrangements among clinicians, providers, and others. The final rule (with some exceptions) became 
effective January 19, 2021. We continue to evaluate what effect, if  any, these rules will have on our 
business. 

Additionally, we are subject to state and foreign equivalents of  each of  the healthcare laws and 
regulations described above, among others, some of  which may be broader in scope and may apply 
regardless of  the payor. Many U.S. states have adopted laws similar to the federal Anti-Kickback 
Statute and False Claims Act, and may apply to our business practices, including, but not limited to, 
research, distribution, sales or marketing arrangements and claims involving healthcare items or 
services reimbursed by non-governmental payors, including private insurers. In addition, some states 
have passed laws that require pharmaceutical companies to comply with the April 2003 Office of  
Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or the 
Pharmaceutical Research and Manufacturers of  America’s Code on Interactions with Healthcare 
Professionals. Several states also impose other marketing restrictions or require pharmaceutical 
companies to make marketing or price disclosures to the state. There are ambiguities as to what is 
required to comply with these state requirements and if  we fail to comply with an applicable state 
law requirement, we could be subject to penalties. Finally, there are state and foreign laws governing 
the privacy and security of  health information (e.g., the California Consumer Privacy Act), many of  
which  differ  from  each  other  in  significant  ways  and  often  are  not  preempted  by  HIPAA,  thus 
complicating compliance efforts.  

We may also be subject to additional privacy restrictions. The collection, use, storage, disclosure, 
transfer, or other processing of  personal data regarding individuals in the European Economic Area, 
or EEA, including personal health data, is subject to the General Data Protection Regulation 2016/679 
(GDPR), which became effective on May 25, 2018. The GDPR is wide-ranging in scope and imposes 

Orchard Therapeutics plc  75

 
UK STATUTORY STRATEGIC REPORT 
continued 

numerous requirements on companies that process personal data, including requirements relating 
to processing health and other sensitive data, obtaining consent of  the individuals to whom the 
personal  data  relates,  providing  information  to  individuals  regarding  data  processing  activities, 
implementing  safeguards  to  protect  the  security  and  confidentiality  of   personal  data,  providing 
notification of  data breaches, and taking certain measures when engaging third-party processors. 
The GDPR also imposes strict rules on the transfer of  personal data to countries outside the European 
Union, including the United States, and permits data protection authorities to impose large penalties 
for violations of  the GDPR, including potential fines of  up to €20 million or 4% of  annual global 
revenues, whichever is greater. The GDPR also confers a private right of  action on data subjects and 
consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and 
obtain compensation for damages resulting from violations of  the GDPR. In addition, the GDPR 
includes restrictions on cross-border data transfers. Compliance with the GDPR will be a rigorous 
and time-intensive process that may increase our cost of  doing business or require us to change our 
business practices, and despite those efforts, there is a risk that we may be subject to fines and 
penalties, litigation, and reputational harm in connection with our European activities. 

Because of  the breadth of  these laws and the narrowness of  the statutory exceptions and safe 
harbors available, it is possible that some of  our business activities could be subject to challenge 
under one or more of  such laws.  

Violations of  fraud and abuse laws may be punishable by criminal and/or civil sanctions, including 
penalties, fines, imprisonment and/or exclusion or suspension from federal and state healthcare 
programs such as Medicare and Medicaid and debarment from contracting with the U.S. government. 
In addition, private individuals have the ability to bring actions on behalf  of  the U.S. government 
under the federal False Claims Act as well as under the false claims laws of  several states.  

Law enforcement authorities are increasingly focused on enforcing fraud and abuse laws, and it is 
possible that some of  our practices may be challenged under these laws. Efforts to ensure that our 
current and future business arrangements with third parties, and our business generally, will comply 
with  applicable  healthcare  laws  and  regulations  will  involve  substantial  costs.  If   our  operations, 
including our arrangements with physicians and other healthcare providers are found to be in violation 
of  any of  such laws or any other governmental regulations that apply to us, we may be subject to 
penalties, including, without limitation, administrative, civil and criminal penalties, damages, fines, 
disgorgement, contractual damages, reputational harm, diminished profits and future earnings, the 
curtailment  or  restructuring  of   our  operations,  exclusion  from  participation  in  federal  and  state 
healthcare programs (such as Medicare and Medicaid), and imprisonment, any of  which could 
adversely affect our ability to operate our business and our financial results. In addition, our gene 
therapy  programs  for  Strimvelis  and  Libmeldy  were  approved  by  the  EMA  in  2016  and  2020, 
respectively, and the approval and commercialization of  Strimvelis and Libmeldy subjects us to 
foreign equivalents of  the healthcare laws mentioned above, among other foreign laws. The approval 
and commercialization of  any of  our other gene therapies outside the United States will also likely 
subject us to foreign equivalents of  the healthcare laws mentioned above, among other foreign laws.  

If  any of  the physicians or other healthcare providers or entities with whom we expect to do business 
are found to be not in compliance with applicable laws, they may be subject to criminal, civil or 
administrative sanctions, including exclusions from government funded healthcare programs, which 
may also adversely affect our business.

UK STATUTORY STRATEGIC REPORT 
continued 

The risk of  our being found in violation of  these laws is increased by the fact that many of  these laws 
have not been fully interpreted by the regulatory authorities or the courts, and their provisions are 
open to a variety of  interpretations. 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. The shifting compliance environment 
and the need to build and maintain a robust system to comply with multiple jurisdictions with different 
compliance and reporting requirements increases the possibility that a healthcare company may 
violate one or more of  the requirements. Efforts to ensure that our business arrangements with third 
parties will comply with applicable healthcare laws and regulations will involve substantial cost.  

Healthcare reform  
A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government 
authorities and other payors have attempted to control costs by limiting coverage and the amount of  
reimbursement for particular medical products. For example, in March 2010, the Patient Protection 
and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of  2010, 
or ACA, was enacted, which, among other things, increased the minimum Medicaid rebates owed 
by most manufacturers under the Medicaid Drug Rebate Program; introduced a new methodology 
by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated 
for drugs that are inhaled, infused, instilled, implanted or injected; extended the Medicaid Drug 
Rebate Program to utilization of  prescriptions of  individuals enrolled in Medicaid managed care 
plans; imposed mandatory discounts for certain Medicare Part D beneficiaries as a condition for 
manufacturers’ outpatient drugs coverage under Medicare Part D; subjected drug manufacturers to 
new annual, nondeductible fees based on pharmaceutical companies’ share of  sales to federal 
healthcare programs; imposed a new federal excise tax on the sale of  certain medical devices; 
expanded healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback 
Statute, new government investigative powers and enhanced penalties for non-compliance; expanded 
eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid 
coverage to additional individuals with income at or below 133% of  the federal poverty level, thereby 
potentially increasing manufacturers’ Medicaid rebate liability; expanded the entities eligible for 
discounts under the PHS Act’s pharmaceutical pricing program, also known as the 340B Drug Pricing 
Program; created new requirements to report financial arrangements with physicians and teaching 
hospitals, commonly referred to as the Physician Payments Sunshine Act; created a new requirement 
to annually report the identity and quantity of  drug samples that manufacturers and authorized 
distributors of  record provide to physicians; created a new Patient Centered Outcomes Research 
Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research, 
along with funding for such research; and established the Center for Medicare Innovation at the CMS 
to test innovative payment and service delivery models to lower Medicare and Medicaid spending.  

Some of  the provisions of  the ACA have yet to be implemented, and there have been legal and 
political challenges to certain aspects of  the ACA. Since January 2017, President Trump has signed 
two  executive  orders  and  other  directives  designed  to  delay,  circumvent,  or  loosen  certain 
requirements mandated by the ACA. On January 20, 2017, President Trump 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 burden on states or a cost, fee, tax, penalty or regulatory burden on individuals, healthcare 
providers, health insurers, or manufacturers of  pharmaceuticals or medical devices. On October 13, 
2017,  President  Trump  signed  an  Executive  Order  terminating  the  cost-sharing  subsidies  that 
reimburse  insurers  under  the  ACA.  The  Trump  administration  has  concluded  that  cost-sharing 
reduction, or CSR, payments to insurance companies required under the ACA have not received 
necessary appropriations from Congress and announced that it will discontinue these payments

continued 

immediately until those appropriations are made. The loss of  the CSR payments is expected to 
increase premiums on certain policies issued by qualified health plans under the ACA. Several state 
Attorneys General filed suit to stop the administration from terminating the subsidies, but their request 
for a restraining order was denied by a federal judge in California on October 25, 2017. On August 
14, 2020, the U.S. Court of  Appeals for the Federal Circuit ruled in two separate cases that the federal 
government is liable for the full amount of  unpaid CSRs for the years preceding and including 2017. 
For CSR claims made by health insurance companies for years 2018 and later, further litigation will 
be required to determine the amounts due, if  any. Further, on June 14, 2018, the U.S. Court of  Appeals 
for the Federal Circuit ruled that the federal government was not required to pay more than $12 billion 
in ACA risk corridor payments to third-party payors who argued the payments were owed to them. 
On April 27, 2020, the United States Supreme Court reversed the U.S. Court of  Appeals for the 
Federal Circuit decision and remanded the case to the U.S. Court of  Federal Claims, concluding the 
government has an obligation to pay these risk corridor payments under the relevant formula. 

Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part 
of  the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the 
implementation of  certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs 
Act of  2017, or Tax Act, includes a provision repealing, effective January 1, 2019, the tax-based 
shared  responsibility  payment  imposed  by  the  ACA  on  certain  individuals  who  fail  to  maintain 
qualifying health coverage for all or part of  a year that is commonly referred to as the “individual 
mandate.” On December 14, 2018, a federal district court in Texas ruled the individual mandate is a 
critical and inseverable feature of  the ACA, and therefore, because it was repealed as part of  the 
Tax Act, the remaining provisions of  the ACA are invalid as well. On December 18, 2019, the Fifth 
Circuit U.S. Court of  Appeals held that the individual mandate is unconstitutional, and remanded the 
case to the lower court to reconsider its earlier invalidation of  the full ACA. On March 2, 2020, the 
United States Supreme Court granted the petitions for writs of  certiorari to review this case and held 
oral arguments on November 10, 2020. It is unclear what effect this will have on the status of  the ACA 
and our business. In December 2018, CMS published a final rule permitting further collections and 
payments to and from certain ACA qualified health plans and health insurance issuers under the 
Affordable Care Act risk adjustment program in response to the outcome of  the federal district court 
litigation regarding the method CMS uses to determine this risk adjustment. Since then, the ACA risk 
adjustment program payment parameters have been updated annually. In addition, CMS published 
a final rule that would give states greater flexibility, starting in 2020, in setting benchmarks for insurers 
in the individual and small group marketplaces, which may have the effect of  relaxing the essential 
health benefits required under the ACA for plans sold through such marketplaces. 

On January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal 
year 2018 that delayed the implementation of  certain ACA -mandated fees, including the so-called 
“Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on 
certain health insurance providers based on market share, and the medical device excise tax on 
non-exempt medical devices; however, on December 20, 2019, President Trump signed into law the 
Further Consolidated Appropriations Act (H.R. 1865), which repealed the Cadillac tax, the health 
insurance provider tax, and the medical device excise tax. Other legislative changes have been 
proposed  and  adopted  in  the  United  States  since  the  Affordable  Care  Act  was  enacted.  The 
Bipartisan  Budget  Act  of   2018,  or  the  BBA,  among  other  things,  amends  the  ACA,  effective 
January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as 
the “donut hole”.

continued 

Other  legislative  changes  have  been  proposed  and  adopted  since  the  ACA  was  enacted.  For 
example, in August 2011, President Obama signed into law the Budget Control Act of  2011, which, 
among  other  things,  created  the  Joint  Select  Committee  on  Deficit  Reduction  to  recommend  to 
Congress proposals in spending reductions. The Joint Select Committee on Deficit Reduction did 
not achieve a targeted deficit reduction of  at least $1.2 trillion for fiscal years 2012 through 2021, 
triggering  the  legislation’s  automatic  reduction  to  several  government  programs.  This  includes 
aggregate reductions to Medicare payments to providers of  up to 2% per fiscal year, which went into 
effect beginning on April 1, 2013 and, due to legislation amendments to the statute, including the 
BBA,  will  stay  in  effect  through  2030  unless  additional  Congressional  action  is  taken.  However, 
pursuant to the Coronavirus Aid, Relief  and Economic Security Act, or CARES Act, and subsequent 
legislation, these Medicare sequester reductions are suspended from May 1, 2020 through March 
31, 2021 due to the COVID-19 pandemic. In January 2013, the American Taxpayer Relief  Act of  2012 
was signed into law, which, among other things, further reduced Medicare payments to several types 
of  providers, including hospitals, imaging centers and cancer treatment centers, and increased the 
statute of  limitations period for the government to recover overpayments to providers from three to 
five years.  

Additionally, there has been increasing legislative and enforcement interest in the United States with 
respect  to  specialty  drug  pricing  practices.  Specifically,  there  have  been  several  recent  U.S. 
Congressional inquiries and proposed and enacted federal and state legislation designed to, among 
other things, bring more transparency to drug pricing, reduce the cost of  prescription drugs under 
Medicare, review the relationship between pricing and manufacturer patient programs, and reform 
government  program  reimbursement  methodologies  for  drugs.  At  the  federal  level,  the  Trump 
administration’s budget proposal for fiscal year 2021 includes a $135 billion allowance to support 
legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug 
costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. On March 
10, 2020, the Trump administration sent “principles” for drug pricing to Congress, calling for legislation 
that would, among other things, cap Medicare Part D beneficiary out-of-pocket pharmacy expenses, 
provide an option to cap Medicare Part D beneficiary monthly out-of-pocket expenses, and place 
limits on pharmaceutical price increases. Further, the Trump administration also previously released 
a “Blueprint”, or plan, to lower drug prices and reduce out of  pocket costs of  drugs that contains 
additional proposals to increase drug manufacturer competition, increase the negotiating power of  
certain federal healthcare programs, incentivize manufacturers to lower the list price of  their products, 
and reduce the out of  pocket costs of  drug products paid by consumers. HHS has already started 
the process of  soliciting feedback on some of  these measures and, at the same, is immediately 
implementing others under its existing authority. For example, in May 2019, CMS issued a final rule 
to allow Medicare Advantage Plans the option of  using step therapy, a type of  prior authorization, for 
Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that became 
effective January 1, 2019. In addition, there has been several changes to the 340B drug pricing 
program, which imposes ceilings on prices that drug manufacturers can charge for medications sold 
to certain health care facilities. On December 27, 2018, the District Court for the District of  Columbia 
invalidated  a  reimbursement  formula  change  under  the  340B  drug  pricing  program,  and  CMS 
subsequently altered the FYs 2019 and 2018 reimbursement formula on specified covered outpatient 
drugs  (“SCODs”).  The  court  ruled  this  change  was  not  an  “adjustment”  which  was  within  the 
Secretary’s  discretion  to  make  but  was  instead  a  fundamental  change  in  the  reimbursement 
calculation. However, most recently, on July 31, 2020, the U.S. Court of  Appeals for the District of  
Columbia Circuit overturned the district court’s decision and found that the changes were within the 
Secretary’s authority. On September 14, 2020, the plaintiffs-appellees filed a Petition for Rehearing 
En Banc (i.e., before the full court), but was denied on October 16, 2020. It is unclear how these 
developments could affect covered hospitals who might purchase our future products and affect the 

Orchard Therapeutics plc  79

 
UK STATUTORY STRATEGIC REPORT 
continued 

rates we may charge such facilities for our approved products in the future, if  any. While a number of  
these and other proposed measures will require authorization through additional legislation to become 
effective, Congress and has indicated that it will continue to seek new legislative and/or administrative 
measures to control drug costs.  

Further, on July 24, 2020 and September 13, 2020, President Trump signed several Executive Orders 
aimed at lowering drug pricing that seek to implement several of  the administration’s proposals. The 
FDA also released a final rule on September 24, 2020, which went into effect on November 30, 2020, 
providing guidance for states to build and submit importation plans for drugs from Canada. Further, 
on November 20 2020 CMS issued an Interim Final Rule implementing the Most Favored Nation, or 
MFN, Model under which Medicare Part B reimbursement rates will be calculated for certain drugs 
and biologicals based on the lowest price drug manufacturers receive in Organization for Economic 
Cooperation and Development countries with a similar gross domestic product per capita. The MFN 
Model regulations mandate participation by identified Part B providers and will apply in all U.S. states 
and territories for a seven-year period beginning January 1, 2021 and ending December 31, 2027. 
The Interim Final Rule has not been finalized and is subject to revision and challenge. Additionally, on 
November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions 
from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy 
benefit managers, unless the price reduction is required by law. The rule also creates a new safe 
harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee 
arrangements between pharmacy benefit managers and manufacturers. Although a number of  these, 
and other proposed measures may require authorization through additional legislation to become 
effective, and the Biden administration may reverse or otherwise change these measures, Congress 
has indicated that it will continue to seek new legislative measures to control drug costs. 

Individual states in the United States have also increasingly passed legislation and implemented 
regulations  designed  to  control  pharmaceutical  product  pricing,  including  price  or  patient 
reimbursement constraints, discounts, restrictions on certain product access and marketing cost 
disclosure and transparency measures, and, in some cases, designed to encourage importation from 
other countries and bulk purchasing.  

Further, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina 
Right to Try Act of  2017, or the Right to Try Act, was signed into law. The law, among other things, 
provides a federal framework for certain patients to request access to certain investigational new 
drug products that have completed a Phase I clinical trial and that are undergoing investigation for 
FDA approval. There is no obligation for a pharmaceutical manufacturer to make its drug products 
available to eligible patients as a result of  the Right to Try Act. 

Coverage and reimbursement  
Significant uncertainty exists as to the coverage and reimbursement status of  any gene therapies for 
which we obtain regulatory approval. In the United States and markets in other countries, sales of  
any gene therapies for which we receive regulatory approval for commercial sale will depend, in part, 
on  the  availability  of   coverage  and  reimbursement  from  payors.  Payors  include  government 
authorities, managed care providers, private health insurers and other organizations. Patients who 
are prescribed treatments for their conditions and providers generally rely on these third-party payors 
to reimburse all or part of  the associated healthcare. The process for determining whether a payor 
will provide coverage for a product may be separate from the process for setting the reimbursement 
rate that the payor will pay for the product. Payors may limit coverage to specific products on an 

80  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

approved list, or formulary, which might not include all of  the FDA-approved products for a particular 
indication. A decision by a payor not to cover our gene therapies could reduce physician utilization 
of  our products once approved and have a material adverse effect on our sales, results of  operations 
and financial condition. Moreover, a payor’s decision to provide coverage for a product does not imply 
that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may 
not be available to enable us to maintain price levels sufficient to realize an appropriate return on our 
investment in product development and manufacturing costs. Further, due to the COVID-19 pandemic, 
millions  of   individuals  have  lost  or  may  lose  employer-based  insurance  coverage,  which  may 
adversely affect our ability to commercialize our products in certain jurisdictions. 

In addition, coverage and reimbursement for products can differ significantly from payor to payor. 
One payor’s decision to cover a particular medical product or service does not ensure that other 
payors will also provide coverage for the medical product or service, or will provide coverage at an 
adequate reimbursement rate. In the United States, the principal decisions about reimbursement for 
new medicines are typically made by the Centers for Medicare & Medicaid Services, or CMS, an 
agency within the U.S. Department of  Health and Human Services. CMS decides whether and to 
what extent a new medicine will be covered and reimbursed under Medicare and private payors tend 
to follow CMS to a substantial degree. 

Additionally, the coverage determination process will require us to provide scientific and clinical 
support for the use of  our products to each payor separately and will be a time-consuming process.  

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. In order to 
obtain  and  maintain  coverage  and  reimbursement  for  any  product,  we  may  need  to  conduct 
expensive evidence generation studies in order to demonstrate the medical necessity and cost-
effectiveness of  such a product, in addition to the costs required to obtain regulatory approvals. If  
payors do not consider a product to be cost-effective compared to current standards of  care , they 
may not cover the product as a benefit under their plans or, if  they do, the level of  payment may not 
be sufficient to allow a company to cover its costs or make a profit.  

Outside of  the United States, the pricing of  pharmaceutical products is subject to governmental 
control in many countries. For example, in the EU, pricing and reimbursement schemes vary widely 
from  country  to  country.  Some  countries  provide  that  products  may  be  marketed  only  after  a 
reimbursement price has been agreed with the government authority. Furthermore, some countries 
may  require  the  completion  of   additional  studies  that  compare  the  effectiveness  and/or  cost-
effectiveness  of   a  particular  therapy  to  current  standards  of   care  as  part  of   so-called  health 
technology assessments, or HTAs, in order to obtain reimbursement or pricing approval. Additionally, 
there may be a need for activities to secure reimbursement for procedures associated with products 
administered in a hospital setting, such as Libmeldy, under the diagnosis-related group, or DRG, 
system, whereby a billing code may not exist or may be currently insufficient to cover the cost of  the 
procedure.  In  other  instances,  countries  may  monitor  and  control  product  volumes  and  issue 
guidance to physicians to limit prescriptions in the form of  treatment policies. Efforts to control prices 
and utilization of  pharmaceutical products and medical devices will likely continue as countries 
attempt to manage healthcare expenditures.

Key Performance Indicators (KPIs) 
We do not consider traditional financial measures to be key performance indicators at this stage of  
development of  our business. Management closely monitors cash position and runway, as well as 
our research and development expenses. In addition, we assess our performance through clinical 
and regulatory advancement of  our programs. In 2020, we unveiled a new Company strategic plan 
prioritizing our high need and high value indications, as well as expansion into less rare indications. 
From a clinical perspective, we began research on and announced new preclinical programs in 
frontotemporal dementia with progranulin mutations (GRN-FTD), amyotrophic lateral sclerosis (ALS), 
and the NOD2 mutation as a Crohn’s disease genetic target. Additionally, we have presented interim 
data from ongoing proof-of-concept trial for OTL-203 for MPS-I. From a regulatory perspective, In 
December 2020, our lead program OTL-200 was approved in the EU, United Kingdom, Iceland, 
Liechtenstein and Norway under the brand name Libmeldy for eligible patients with early onset MLD. 
Further, in November 2020, we announced FDA clearance for an IND application for OTL-200 in the 
United States.  

Employees and Human Capital Resources 
As of  December 31, 2020, and 2019 we had 224 and 253 full-time employees, respectively. We have 
no collective bargaining agreements with our employees, and we have not experienced any work 
stoppages. We consider our relationship with our employees to be positive. We monitor employee 
engagement through an annual survey and develop a prioritized action plan on an annual basis to 
address  any  areas  in  need  of   attention.  Our  human  capital  objectives  include,  as  applicable, 
identifying,  recruiting,  developing,  retaining,  and  incentivizing  our  existing  and  prospective 
employees, as well as optimizing the overall employee experience. The principal purposes of  our 
incentive  plans  are  to  attract,  retain  and  motivate  our  employees.  The  granting  of   share-based 
compensation awards are designed to reward selected employees for long-term shareholder value 
creation  and  our  cash-based  performance  bonus  awards  reward  the  achievement  of   annual 
performance goals. The health and safety of  our employees, customers and communities are of  
primary concern. During the COVID-19 pandemic, we have taken significant steps to protect our 
workforce including but not limited to, working remotely, and implementing social distancing protocols 
consistent  with  guidelines  issued  by  federal,  state,  and  local  laws.  In  2020,  we  launched  a 
comprehensive initiative to enhance diversity, inclusion and belonging. 

Summary of the Principal Risks and Uncertainties 
Our business is subject to numerous risks and uncertainties that you should be aware of  in evaluating 
our business. These risks include, but are not limited to, the following: 

(cid:129) We have incurred net losses since inception. We expect to incur net losses for the foreseeable 

future and may never achieve or maintain profitability. 

(cid:129) We will need additional funding, which may not be available on acceptable terms, or at all. Failure 
to obtain this necessary capital when needed may force us to delay, limit or terminate our product 
development efforts or other operations. 

(cid:129) Our gene therapy product candidates are based on a novel technology, which makes it difficult 
to predict the time and cost of  product candidate development and of  subsequently obtaining 
regulatory approval. 

(cid:129)

The results from our clinical trials for OTL-200 for metachromatic leukodystrophy, or MLD, OTL-103 
for Wiskott Aldrich syndrome, or WAS, and for any of  our other product candidates may not be 
sufficiently robust to support marketing approval or the submission of  marketing approval. Before 
we submit our product candidates for marketing approval, the U.S. Food and Drug Administration, 

82  Orchard Therapeutics plc 

 
UK STATUTORY STRATEGIC REPORT 
continued 

or FDA, and/or the European Medicines Agency, or EMA, may require us to conduct additional 
clinical trials, or evaluate patients for an additional follow-up period. 

(cid:129)

Interim data and ad hoc analyses are preliminary in nature. Success in preclinical studies or early 
clinical trials may not be indicative of  results obtained in later trials. 

(cid:129) Gene therapies are novel, complex and difficult to manufacture. We have limited manufacturing 
experience, and we rely on third party manufacturers that are often our single source of  supply. 
We  could  experience  manufacturing  problems  that  result  in  delays  in  the  development  or 
commercialization of  our commercial products or our product candidates or otherwise harm our 
business. 

(cid:129)

Libmeldy™, Strimvelis® and our product candidates and the process for administering Libmeldy, 
Strimvelis and our product candidates may cause serious or undesirable side effects or adverse 
events or have other properties that could delay or prevent regulatory approval, limit commercial 
potential or result in significant negative consequences for our company.  

(cid:129) We may find it difficult to enroll patients in our clinical trials, which could delay or prevent us from 

proceeding with clinical trials of  our product candidates. 

(cid:129)

(cid:129)

If  we are unable to establish effective sales and marketing capabilities or enter into agreements 
with third parties to market, sell and gain reimbursement for Libmeldy and our product candidates 
that may be approved, we may not be successful in commercializing Libmeldy or our product 
candidates if  and when approved, and we may be unable to generate product revenue. 

If   the  size  and  value  of   the  market  opportunities  for  our  commercial  products  or  product 
candidates are smaller than our estimates, or if  we have difficulty in finding patients that meet 
eligibility requirements for Libmeldy, Strimvelis or any of  our product candidates, if  approved, our 
product revenues may be adversely affected and our business may suffer.  

(cid:129) We  face  significant  competition  in  our  industry  and  there  can  be  no  assurance  that  our 
commercial products or our product candidates, if  approved, will achieve acceptance in the 
market over existing established therapies. In addition, our competitors may develop therapies 
that  are  more  advanced  or  effective  than  ours,  which  may  adversely  affect  our  ability  to 
successfully market or commercialize any of  our product candidates. 

(cid:129) Business interruptions resulting from the COVID-19 pandemic or similar public health crises have 
caused and may cause or continue to cause a disruption to the development of  our product 
candidates and adversely impact our business.  

(cid:129) We may not be able to protect our intellectual property rights throughout the world. 

(cid:129) We may become subject to claims that we are infringing certain third party patents, for example, 
patents relating to lentiviral vectors, or other third party intellectual property rights, any of  which 
may prevent or delay our development and commercialization efforts and have a material adverse 
effect on our business. 

(cid:129) We have in the past, and in the future may, enter into collaborations with third parties to develop 
or commercialize product candidates. If  these collaborations are not successful, our business 
could be adversely affected.  

(cid:129)

The market price of  our ADSs may be highly volatile and may fluctuate due to factors beyond our 
control. 

Information on Environmental Matters 
The Company is required to measure and report its greenhouse gas emissions in accordance with 
the provisions of  the UK Companies Act 2006 (UK Statutory Strategic Report and UK Statutory

Directors’ Report) Regulations 2013. Our greenhouse gas emissions estimates for 2020 has been 
prepared in accordance with the U.K. Government’s Department for Environment, Food and Rural 
Affairs (Defra) guidance document “Environmental Reporting Guidelines: Including Mandatory GHG 
emissions reporting guidance, from March 2019”. 

                                                                                                                                                         2020                      2019 

Estimated greenhouse gas emissions from purchased electricity,  
heat, steam, or cooling for our own use (tCO2e)                                                     230.5                 303.6

We have used evidence and estimates derived from evidence provided by our energy supply partners 
and lessors to generate our disclosure of  emissions for the year. These include the purchase of  
electricity, heat, steam or cooling either directly from our energy supply partners, or through utility 
bills from our lessors. Standard emission factors from Defra’s GHG Conversion Factors Repository 
were applied to estimate emissions. The Group considers that the intensity ratio of  tonnes of  carbon 
dioxide per full-time equivalent employee is a suitable metric for its operations. 

Electricity, heating, and cooling usage at our leased facilities in the United States and United Kingdom 
drive  the  majority  of   our  greenhouse  gas  emissions.  Greenhouse  gas  emissions  generated  by 
company-owned facilities declined in 2020 as compared to 2019 as we transitioned to a remote 
workforce due to the COVID-19 pandemic. 

Diversity 
Appointments within the Group are made on merit according to the balance of  skills and experience 
offered  by  prospective  candidates.  While  acknowledging  the  benefits  of   diversity,  individual 
appointments are made irrespective of  personal characteristics such as race, disability, gender, 
sexual orientation, religion, or age. A breakdown of  employment statistics as of  31 December 2020

Post Balance Sheet Events 
Securities Purchase Agreement 
On February 9, 2021, the Company issued and sold (i) 20,900,321 ordinary shares, nominal value 
£0.10 per share, at a purchase price of  $6.22 per share (the “Purchase Price”), which was the closing 
sale price of  the Company’s ADSs on the Nasdaq Global Select Market on February 4, 2021, and (ii) 
3,215,434 non-voting ordinary shares, nominal value £0.10 per share, at the Purchase Price (the 
“Private  Placement”).  The  Private  Placement  resulted  in  net  proceeds  to  the  Company  of  
approximately $144.0 million after deducting placement agent fees. The ordinary shares and non-
voting ordinary shares were sold pursuant to a securities purchase agreement entered into between 
the Company and the purchasers named therein on February 4, 2021.

Going Concern 
At  31  December  2020,  the  Group  held  cash,  cash  equivalents  and  marketable  securities  of  
$191.9 million, and the Company held cash and marketable securities of  $134.6 million. The directors 
have prepared a forecast through 2022 and expect that its cash, cash equivalents, and marketable 
securities on hand as of  December 31, 2020 of  $191.9 million, together with the proceeds from the 
Private  Placement  of   $150.0  million  of   ordinary  shares  that  closed  in  February  2021  (see  “Post 
Balance Sheet Events” section above), will be sufficient to fund its operations and capital expenditure 
requirements for at least the next twelve months. The directors have considered the effect of  the 
COVID-19 pandemic on our forecast, and have determined it does not have an effect on our ability 
to operate as a going concern for at least 12 months from the issuance of  these consolidated financial 
statements.  Therefore,  the  directors  have  at  the  time  of   approving  the  financial  statements,  a 
reasonable  expectation  that  the  Group  and  Company  has  adequate  resources  to  continue  in 
operational existence for the foreseeable future. Accordingly, the Group and Company continues to 
adopt the going concern basis of  accounting in preparing the financial statements. 

Employee Involvement 
The Company has outlined key human capital disclosures in our Strategic Report on page 82 of  this 
Annual Report. 

Greenhouse gas emissions 
The Company has outlined its greenhouse gas emissions estimate in the “Environmental Matters” 
section of  the Strategic Report beginning on page 82 of  this Annual Report. 

Financial Risk Management 
Credit and Interest Rate Risk 
As of  December 31, 2020, we had cash, cash equivalents, marketable securities, and restricted cash 
of  $196.2 million. Our exposure to interest rate sensitivity is impacted by changes in the underlying 
UK and U.S. bank interest rates. Our surplus cash has been invested in corporate bonds, commercial 
paper, U.S. treasuries, and money market accounts. We have not entered into investments for trading 
or  speculative  purposes.  Due  to  the  conservative  nature  of   our  investment  portfolio,  which  is 
predicated on capital preservation of  investments with short-term maturities, we do not believe an 
immediate one percentage point change in interest rates would have a material effect on the fair 
market value of  our portfolio, and therefore we do not expect our operating results or cash flows to 
be significantly affected by changes in market interest rates.  

We have borrowed $25.0 million under our credit facility. Amounts outstanding under the credit facility 
bear interest at a variable interest rate of  6% plus LIBOR. As of  December 31, 2020, the carrying 
value of  the term loans under the credit facility was $25.1 million, $4.9 million of  which was classified 
as a current liability, and $20.2 million of  which was classified as a long-term liability. 

Liquidity Risk 
From our inception through December 31, 2020, we have not generated significant revenue from 
product sales and incurred significant operating losses and negative cash flows from our operations. 
We acquired our commercial product Strimvelis from GSK in April 2018, and our product candidates 
are in various phases of  preclinical and clinical development. In December 2020, the European 
Commission granted full, or standard, marketing authorization for Libmeldy. We expect to launch 
Libmeldy in Europe and generate product sales as early as the first half  of  2021. To date, we have 
financed our operations primarily with proceeds from the sale of  ADSs in our IPO and follow-on 
offering, proceeds from the sale of  convertible preferred shares, proceeds from share issuances 
from employee equity plans, receipts from the United Kingdom research and development tax credit,

continued  

reimbursements from our research agreement with UCLA and, following transfer of  the ADA-SCID 
research program sponsorship from UCLA to us in July 2018, a grant from the California Institute of  
Regenerative Medicine (“CIRM”), and our Credit Facility.  

On February 27, 2020, we entered into a Sales Agreement with Cowen and Company, LLC, as agent, 
relating to an “at the market offering,” pursuant to which we may issue and sell ADSs representing 
our ordinary shares, having an aggregate offering price of  up to $100.0 million. As of  December 31, 
2020, we have not sold any shares under the Sales Agreement. 

Through December 31, 2020, we have received net proceeds of  $335.2 million from the sale of  ADSs 
in our initial public offering and follow-on offering, net proceeds of  $283.4 million from sales of  
convertible preferred shares, $24.5 million in net proceeds from our Credit Facility, $33.9 million in 
receipts associated with our United Kingdom research and development tax credit of  , $7.1 million 
in proceeds from share issuances from employee equity plans, and reimbursement of  $8.2 million 
from our agreement with CIRM, which was formerly a subcontract agreement with UCLA. As of  
December 31, 2020, we had cash, cash equivalents, and marketable securities of  $191.9 million, 
excluding restricted cash.  

On February 9, 2021, we issued and sold (i) 20,900,321 ordinary shares, nominal value £0.10 per 
share, at a purchase price of  $6.22 per share (the “Purchase Price”), which was the closing sale 
price of  our ADSs on the Nasdaq Global Select Market on February 4, 2021, and (ii) 3,215,434 non-
voting  ordinary  shares,  nominal  value  £0.10  per  share,  at  the  Purchase  Price  (the  “Private 
Placement”). The Private Placement resulted in net proceeds to us of  approximately $144.0 after 
deducting placement agent fees. The ordinary shares and non-voting ordinary shares were sold 
pursuant to a securities purchase agreement we entered into with the purchasers named therein on 
February 4, 2021. 

We currently have no ongoing material financing commitments, such as lines of  credit or guarantees, 
that are expected to affect our liquidity over the next five years, other than our manufacturing, lease, 
and debt obligations described in our consolidated financial statements. 

Foreign exchange risk 
The Company is exposed to foreign currency exchange risk because it primarily operates in the 
United Kingdom and the United States. The reporting currency of  the Company is the U.S. dollar. 
The Company has determined the functional currency of  the ultimate parent company, Orchard 
Therapeutics plc, is U.S. dollars because it predominantly raises finance and expends cash in U.S. 
dollars, and expects to continue to do so in the future. Monetary assets and liabilities denominated 
in currencies other than the functional currency are translated into the functional currency of  the 
relevant entity at rates of  exchange prevailing at the balance sheet dates. Non-monetary assets and 
liabilities  denominated  in  foreign  currencies  are  translated  into  the  functional  currency  at  the 
exchange rates prevailing at the date of  the transaction. Exchange gains or losses arising from foreign 
currency  transactions  are  included  in  the  determination  of   net  income  (loss)  for  the  respective 
periods. We recorded realized and unrealized foreign currency gains of  $3.4 million and $1.4 million 
for the years ended December 31, 2020 and 2019. These foreign currency transaction gains and 
losses are included in other income (expense) in our consolidated statement of  operations and 
comprehensive loss.  

Assets and liabilities have been translated at the exchange rates at the balance sheet date, while 
revenue and expenses are translated at the average exchange rates over the reporting period and 
shareholders’ equity amounts are translated based on historical exchange rates as of  the date of  
each transaction. Translation adjustments are not included in determining net income (loss) but are

UK STATUTORY DIRECTORS’ REPORT 
continued 

included in our foreign currency translation adjustment to other comprehensive loss, a component 
of  shareholders’ equity. 

We do not currently engage in currency hedging activities in order to reduce our currency exposure, 
but we may begin to do so in the future. Instruments that may be used to hedge future risks include 
foreign currency forward and swap contracts. These instruments may be used to selectively manage 
risks, but there can be no assurance that we will be fully protected against material foreign currency 
fluctuations.

in respect of  proceedings brought by third parties, which was in force throughout the financial year, 
and remains in force as at the date of  approving the UK Statutory Directors’ Report. 

Independent Auditors 
PricewaterhouseCoopers LLP have expressed their willingness to continue in office as auditors for 
another year. In accordance with Section 418 of  the UK Companies Act 2006, a resolution proposing 
that PricewaterhouseCoopers LLP be re-appointed as auditors of  the Group and Company will be 
proposed at the Annual General Meeting.

DIRECTORS’ REMUNERATION REPORT 

Annual Statement from the Chair of the Compensation Committee 

Dear Shareholder, 

As the Chair of  the Compensation Committee (the “Committee”), I am pleased to present, on behalf  of  
the board of  directors (the “Board”) of  Orchard Therapeutics plc (the “Company” or “Orchard”), the 
Directors’ Remuneration Report for the year ended 31 December 2020 (the “Remuneration Report”). 

The Company’s Remuneration Report, will be subject to an advisory vote at the forthcoming Annual 
General Meeting on 16 June 2021 (the “AGM”). 

Introduction 
Our executive compensation program seeks to incentivize and reward strong corporate performance. 
All compensation decisions at Orchard remain aligned to our key principle of  paying for performance. 
Further, as a global biopharmaceutical company with major operations in the United States and 
Europe we operate within a global marketplace for talent. Given that the market for experienced 
directors and biopharmaceutical executive talent is very competitive, particularly in the United States, 
the  Committee  references  the  US  market  as  the  leading  indicator  for  remuneration  levels  and 
practices. This helps attract and retain directors and motivate the superior executive talent needed 
to successfully manage the Company’s complex global operations. Being consistent in this market 
view of  the United States as the primary benchmark for remuneration practices for our Executive and 
Non-Executive  Directors  is  key  for  the  Company  as  it  builds  its  global  operations  in  a  manner 
designed to deliver sustainable, long-term growth and shareholder value. 

As a Committee, we are  also mindful of  general UK compensation frameworks and investor guidance 
in that regard when making decisions on Orchard’s executive compensation. 

In  many  respects  2020  was  a  year  of   transition  for  Orchard,  with  founder,  Dr  Bobby  Gaspar’s 
appointment as CEO and progress against a new strategic plan to realize the potential of  the HSC 
gene therapy approach. This was all undertaken against the external challenge of  COVID. We also 
celebrated successes in respect of  Libmeldy’s approval in the European Union in December 2020. 

Key remuneration decisions for 2020 
On 18 March 2020, Bobby Gaspar was appointed as Chief  Executive Officer. Dr. Gaspar's annual 
base salary was increased to £440,000, his target annual bonus opportunity was increased to 60% 
of  his base salary. The Committee reviewed this salary against relevant competitive market data and 
that of  the previous incumbent. In relation to this promotion, Dr. Gaspar was granted an option to 
purchase 300,000 of  the Company’s ordinary shares, effective 1 April 2020. In addition, Dr. Gaspar 
was awarded 195,000 Performance Share Units (PSUs) subject to the achievement of  specific clinical 
and regulatory milestones before 31 December 2023.

continued 

2020 Annual Bonus 
Consistent  with  prior  years,  the  annual  bonus  for  2020  was  based  upon  our  stated  corporate 
objectives. These make up a scorecard of  the research, clinical, commercial and operational goals 
which ultimately drive long-term, sustainable and strategic success of  the Company. For the Executive 
Team, the Committee determined a performance score of  100% of  target. This reflects the strong 
performance against the corporate objectives. Details of  the Company’s performance against these 
goals are described in the main body of  this report. For 2020, this represents a bonus of  60% salary 
for  the  CEO.  As  a  Committee,  we  made  the  decision  to  reduce  the  cash  payment  of   executive 
bonuses  and  deliver  only  one  half   in  cash.  The  remaining  half   of   the  executive  bonus  was  an 
additional award of  share options granted in lieu of  this portion of  the bonus, with the number of  
options calculated on a fair value basis. The cash portion of  the bonuses that were replaced by share 
options was added to the all employee bonus pool and facilitated increased bonus awards within 
the Company. 

Remuneration for 2021 
There are no substantial changes to our approach to executive compensation for 2021. No increase 
to Dr. Gaspar’s salary was made for 2021 and his bonus target remains at 60% salary. Consistent 
with our pay for performance philosophy, Dr. Gaspar was granted an annual award of  share options 
in February 2021 alongside an additional option award as part of  the bonus arrangement above. 

Changes to the Board 
Mr. Rothera stepped down from his position as President and Chief  Executive Officer and resigned 
as a director of  the Company on 17 March 2020. Details of  his compensation on termination can be 
found in this report. 

Steven Altschuler was appointed as a Non-Executive Director of   the Company,  effective as of  
3 February 2020. We welcome him to the Board where he also serves on the Board’s Science and 
Technology Committee. 

Conclusion 
The Committee believes that the Directors’ Remuneration Policy has been implemented fairly and 
consistently, as described in this report, and that it will continue to properly motivate our Executive 
Directors to deliver sustainable growth and shareholder value over the long term and to do so in a 
responsible and cost-efficient manner. 

I hope that you find the information in this report helpful, and I look forward to your support at the 
Company’s AGM. 

Yours sincerely, 

Charles Rowland, Jr. 
Chair of  the Compensation Committee

Remuneration Policy 
This part of  the Directors’ Remuneration Report sets out the remuneration policy for the Company. 
The current Directors’ Remuneration Policy (the “Policy”) was put forward for approval by shareholders 
in a binding vote at the AGM on 26 June 2019 and approved with a majority of  91.6% vote in favour 
of  taking effect from the date of  approval and applying for a period of  three years until 2022. 

Key considerations when determining the Remuneration Policy 
The Policy was designed by the Committee with a number of  specific principles in mind: 

(cid:129)

(cid:129)

attract, retain and motivate high calibre senior management and focus them on the delivery of  
the Company’s strategic and business objectives; 

encourage a corporate culture that promotes the highest level of  integrity, teamwork and ethical 
standards; 

(cid:129) be competitive against appropriate market benchmarks (being predominantly the US biotech 
sector) and have a strong link to performance, providing the ability to earn above-market rewards 
for strong performance; 

(cid:129) be simple and understandable, both internally and externally; 

(cid:129)

(cid:129)

encourage  increased  equity  ownership  to  motivate  executives  in  the  overall  interests  of  
shareholders, the Company, employees and customers; and 

take due account of  good governance and promote the long-term success of  the Company. 

In seeking to achieve the above objectives, the Committee is mindful of  the views of  a broad range 
of  stakeholders in the business and accordingly takes account of  a number of  factors when setting 
remuneration including: market conditions; pay and benefits in relevant comparator organisations; 
terms  and  conditions  of   employment  across  the  Company;  the  Company’s  risk  appetite;  the 
expectations of  institutional shareholders; and any specific feedback received from shareholders 
and other stakeholders.

Notes to the policy table 

Legacy arrangements 
For the duration of  this Policy, the Company will honour any commitments made in respect of  current 
or  former  Directors  before  the  date  on  which  either:  (i)  the  Policy  becomes  effective;  or  (ii)  an 
individual becomes a Director, even where not consistent with the Policy set out in this report or 
prevailing at the time such commitment is fulfilled. For the avoidance of  doubt, all outstanding historic 
awards that were granted in connection with, or prior to, listing remain eligible to vest based on their 
original or modified terms. 

Performance conditions 
The choice of  annual bonus performance metrics reflects the Committee’s belief  that any incentive 
remuneration should be appropriately challenging and tied to the delivery of  key strategic objectives 
intended to ensure that Executive Directors are incentivised to deliver across a range of  objectives 
for which they are accountable. The Committee has retained flexibility on the specific measures which 
will be used to ensure that any measures are fully aligned with the strategic imperatives prevailing at 
the time they are set. 

The targets for the bonus scheme for the forthcoming year will be set out in general terms, subject to 
limitations with regards to commercial sensitivity. The full details of  the targets will be disclosed when 
they are in the public domain and are no longer considered commercially sensitive. 

Where used, performance conditions applicable to SOIP awards will be aligned with the Company’s 
objective  of   delivering  superior  levels  of   long-term  value  to  shareholders.  The  full  details  of  
performance conditions will be disclosed when they are in the public domain and are no longer 
commercially sensitive. Prior to each award, the Committee has flexibility to select measures that are 
fully aligned with the strategy prevailing at the time awards are granted. 

100  Orchard Therapeutics plc 

 
 
 
 
DIRECTORS’ REMUNERATION REPORT 
continued 

The Committee will review the calibration of  targets applicable to the annual bonus, and the SOIP in 
years where performance measures apply, annually to ensure they remain appropriate and sufficiently 
challenging, taking into account the Company’s strategic objectives and the interests of  shareholders. 

Differences in remuneration policy between Executive Directors and other 
employees 
The overall approach to reward for employees across the workforce is a key reference point when 
setting the remuneration of  the Executive Directors. When reviewing the salaries of  the Executive 
Directors, the Committee pays close attention to pay and employment conditions across the wider 
workforce and in normal circumstances the increase for Executive Directors will be no higher than 
the average increase for the general workforce. 

The key difference between the remuneration of  Executive Directors and that of  our other employees 
is that, overall, at senior levels, remuneration is increasingly long-term, and ‘at risk’ with an emphasis 
on performance-related pay linked to business performance and share-based remuneration. This 
ensures that remuneration at senior levels will increase or decrease in line with business performance 
and provides alignment between the interests of  Executive Directors and shareholders. In particular, 
long-term incentives are provided only to the most senior executives as they are reserved for those 
considered to have the greatest potential to influence overall levels of  performance. 

Committee discretion in operation of variable pay schemes 
The  Committee  operates  under  the  powers  it  has  been  delegated  by  the  Board.  In  addition,  it 
complies with rules that are either subject to shareholder approval or by approval from the Board. 
These  rules  provide  the  Committee  with  certain  discretions  which  serve  to  ensure  that  the 
implementation  of   the  remuneration  policy  is  fair,  both  to  the  individual  Director  and  to  the 
shareholders. The Committee also has discretions to set components of  remuneration within a range, 
from  time  to  time.  The  extent  of   such  discretions  is  set  out  in  the  relevant  rules,  the  maximum 
opportunity or the performance metrics section of  the policy table above. To ensure the efficient 
administration  of   the  variable  incentive  plans  outlined  above,  the  Committee  will  apply  certain 
operational discretions. 

These include the following: 

(cid:129)

selecting the participants in the plans on an annual basis; 

(cid:129) determining the timing of  grants of  awards and/or payments; 

(cid:129) determining the quantum of  awards and/or payments (within the limits set out in the policy table 

above); 

(cid:129) determining the choice (and adjustment) of  performance measures and targets for each incentive 

plan in accordance with the policy set out above and the rules of  each plan; 

(cid:129) determining  the  extent  of   vesting  based  on  the  assessment  of   performance  and  discretion 
relating  to  measurement  of   performance  in  certain  events  such  as  a  change  of   control  or 
reconstruction; 

(cid:129) making the appropriate adjustments required in certain circumstances, for instance for changes 

in capital structure; 

Orchard Therapeutics plc  101

 
DIRECTORS’ REMUNERATION REPORT 
continued 

(cid:129) determining “good leaver” status, if  applicable, for incentive plan purposes and applying the 

appropriate treatment; and 

(cid:129)

undertaking the annual review of  weighting of  performance measures and setting targets for the 
annual bonus plan and other incentive schemes, where applicable, from year to year. 

If  an event occurs which results in the annual bonus plan or SOIP performance conditions and/or 
targets being deemed no longer appropriate (e.g. material acquisition or divestment), the Committee 
will  have  the  ability  to  make  appropriate  adjustments  to  the  measures  and/or  targets  and  alter 
weightings, provided that the revised conditions are not materially less challenging than the original 
conditions. Any use of  the above discretion would, where relevant, be explained in the Annual Report 
on  Remuneration  and  may,  as  appropriate,  be  the  subject  of   consultation  with  the  Company’s 
major shareholders. 

Shareholder views 
The Board is committed to dialogue with shareholders and intends to engage directly with them and 
their  representative  bodies  when  considering  any  significant  changes  to  our  remuneration 
arrangements. The Compensation Committee will consider shareholder feedback received following 
the AGM, as well as any additional feedback and guidance received from time to time. This feedback 
will be considered by the Committee as it develops the Company’s remuneration framework and 
practices  going  forward.  Assisted  by  its  independent  adviser,  the  Compensation  Committee 
also  actively  monitors  developments  in  the  expectations  of   institutional  investors  and  their 
representative bodies. 

Employment conditions 
The Committee is regularly updated throughout the year on pay and conditions applying to Company 
employees. Where significant changes are proposed to employment conditions elsewhere in the 
Company these are highlighted for the attention of  the Committee at an early stage. 

Other remuneration policies 

Remuneration for new appointments 
Where it is necessary to appoint or replace an Executive Director or to promote an existing Executive 
Director, the Committee’s approach when considering the overall remuneration arrangements in the 
recruitment of  a new Executive Director is to take account of  the calibre, expertise and responsibilities 
of  the individual, his or her remuneration package in their prior role and market rates. Remuneration 
will be in line with our policy and the Committee will not pay more than is necessary to facilitate 
their recruitment. 

The remuneration package for a new Executive Director will be set in accordance with the terms of  
the Company’s approved remuneration policy in force at the time of  appointment. Further details are 
provided below: 

Salary

The  Committee  will  set  a  base  salary  appropriate  to  the  calibre,  experience  and 
responsibilities of  the new appointee. In arriving at a salary, the Committee may take 
into account, amongst other things, the market rate for the role and internal relativities. 

102  Orchard Therapeutics plc 

 
DIRECTORS’ REMUNERATION REPORT 
continued 

The Committee has the flexibility to set the salary of  a new Executive Director at a 
lower  level  initially,  with  a  series  of   planned  increases  implemented  over  the 
following  few  years  to  bring  the  salary  to  the  desired  positioning,  subject  to 
individual performance. 

In exceptional circumstances, the Committee has the ability to set the salary of  a new 
Executive Director at a rate higher than the market level to reflect the criticality of  the 
role and the experience and performance of  the individual. 

Benefits will be consistent with the principles of  the policy. The Company may award 
certain additional benefits and other allowances including, but not limited to, those to 
assist  with  relocation  support,  temporary  living  and  transportation  expenses, 
educational costs for children and tax equalisation to allow flexibility in employing an 
overseas national. 

A  maximum  pension  contribution  of   6%  of   salary  may  be  payable  for  external   
appointments. For an internal appointment, his or her existing pension arrangements 
may continue to operate. Any new Executive Director based outside the UK will be 
eligible to participate in pension or pension allowance, insurance and other benefit 
programmes in line with local practice.

addition, Executive Directors are eligible to participate in the ESPP subject to the 
conditions set forth therein. 

In addition, the Committee may offer additional cash and/or equity-based elements 
in order to “buy-out” remuneration relinquished on leaving a former employer. Any 
awards  made  in  this  regard  may  have  no  performance  conditions,  or  different 
performance conditions, or a different vesting schedule compared to the Company’s 
existing plans, as the Committee considers appropriate. Depending on the timing and 
responsibilities of  the appointment, it may be necessary to set different annual bonus 
or SOIP performance measures and targets as applicable to other Executive Directors. 

The terms of  appointment for a Non-Executive Director would be in accordance with the remuneration 
policy for Non-Executive Directors as set out in the policy table.

Service contracts and termination policy 
Executive Directors have rolling service agreements which may be terminated in accordance with 
the terms of  these agreements. The period of  notice for Executive Directors will not normally exceed 
12 months. Executive Directors’ service agreements are available for inspection at the Company’s 
registered office during normal business hours.

The Company’s policy on remuneration for Executive Directors who leave the Company is set out 
below. The Committee will exercise its discretion when determining amounts that should be paid to 
leavers, taking into account the facts and circumstances of  each case. Generally, in the event of  
termination, the Directors’ service contracts may provide for payment of  basic salary over the notice 
period. Where applicable, the Company may elect to make a payment in lieu of  notice (PILON) 
equivalent in value to basic salary for any unexpired portion of  the notice period. PILON payments 
may  be  made  in  monthly  instalments  or  as  a  lump  sum,  and  the  individual  is  expected  to  take 
reasonable steps to seek alternative income to mitigate the payments. The Company may also pay 
for outplacement services for Executive Directors on termination or the Company may elect to make 
a payment in lieu of  outplacement services. The Company may continue to pay the employer health 
plan premium for the Executive Director on termination for a period of  up to 12 months (up to 18 
months in connection with a change in control). 

Any outstanding incentive awards will be treated in accordance with the plan rules, as follows:

The  Company  is  unequivocally  against  rewards  for  failure;  the  circumstances  of   any  departure, 
including the individual’s performance, would be taken into account in every case. Statutory redundancy 
payments may be made, as appropriate. Service agreements may be terminated summarily without 
notice (or on shorter notice periods) and without payment in lieu of  notice in certain circumstances, 
such as gross misconduct or any other material breach of  the obligations under their employment 
contract. The Company may require the individual to work during their notice period or may place them 
on garden leave during which they would be entitled to salary, benefits and pension only. 

Except in the case of  gross misconduct or resignation, the Company may at its absolute discretion 
reimburse for reasonable professional fees relating to the termination of  employment and, where an 
Executive Director has been required to re-locate, to pay reasonable repatriation costs, including 
possible tax exposure costs. This includes any statutory entitlements or sums to settle or compromise 
claims in connection with a termination (including, at the discretion of  the Committee, reimbursement 
for legal advice and provision of  outplacement services). 

Policy on external appointments 
The Board believes that it may be beneficial to the Company for executives to hold non-executive 
directorships outside the Company. Any such appointments are subject to approval by the Board, 
and the director may retain any fees received at the discretion of  the Board. Dr Gaspar does not 
currently hold any outside directorships.

Independent advisors 
Wholly independent advice on executive remuneration is received from the Executive Compensation 
practice of  Aon plc.. Aon advises on remuneration arrangements and all aspects of  senior executive 
remuneration.  In  2020,  Aon  assisted  the  Committee  and  kept  the  Committee  up  to  date  on 
remuneration trends. During the 2020 financial year, fees charged by Aon for advice provided to the 
Committee for 2020 amounted to $171,329 (excluding VAT). In addition, Aon provided advice to the

prejudices Aon’s position as the Committee’s independent advisor. Goodwin Procter LLP have also

constructing the remuneration arrangements for executive directors and senior employees, the Board, 
advised by the Committee, aims to provide remuneration packages that are competitive and designed 
to attract, retain and motivate Executive Directors and senior employees of  the highest calibre.

granted to Directors are awarded at the market value and therefore the intrinsic value at the time of  grant is zero. 
Details of  all options awarded to individual Directors during the year, including the number of  options under award, 
the exercise price, vesting schedule and the grant date fair value can be found in the tables below. All awards in the

2020 Annual bonus (audited) 
During a series of  meetings in December 2020 and January 2021, the Compensation Committee 
evaluated  achievement  of   the  2020  corporate  objectives  and  each  Executive  Director’s 
individual performance. 

The  Compensation  Committee  reviewed  the  corporate  goals,  below,  and  based  on  the  results 
approved a 100% achievement level of  the 2020 corporate objectives. 

Key achievements against agreed goals were as follows: 

Transition Lead Programs into Approved Therapies – most significantly during the year was the 
receipt  in  December  of   MAA  approval  from  the  European  Commission  for  OTL-200  (MLD)  – 
LibmeldyTM. This is an important and significant achievement for Orchard. Also for OTL-200, an IND 
was filed with the request for RMAT designation in the US. Substantial work and progress was made 
aligning with the FDA on the current clinical dataset for OTL-103 (WAS) which will inform the path to 
a BLA submission. 

Build a World-leading Gene Therapy Pipeline – 2020 saw important steps taken in both OTL-203 
(MPS-I) and OTL -201 (MPS-IIIA). For OTL-203 interim data in the proof-of-concept study in the first 
8 patients in conjunction with TIGET/OSR was presented at ASGCT meeting in April 2020 and EBMT 
meeting in August 2020. We also finalized and submitted a protocol for the registrational study for 
scientific advice. For OTL 201, three patients were enrolled in proof-of-concept study and data on 
first  patient  was  presented  by  a  University  of   Manchester  investigator  at  ASH  meeting  in 
December 2020. 

Generate Competitive Advantage with our CMC Platform – important achievements in the year 
included  the  signing  of   a  stable  cell  line  licence  for  TDT  and  WAS  (July  2020)  as  well  as  the 
identification of  a drug product CDMO partner in the U.S. to initiate technology transfer process. 
Further, a transduction enhancer combination was identified that delivers at least 50% reduction in 
vector requirement at research scale. 

Achieve Financial Targets & Position for Strong Commercial Launch – in relation to Libmeldy, a 
new-born screening pilot was initiated in the U.S. and one in Europe for Libmeldy with contracts 
executed in New York (US) and Germany (EU) in addition to pricing corridor and access strategy in 
the EU and the establishment of  an operational launch structure in EU countries, Middle East & Turkey. 

Financially,  the  business  operated  within  approved  limits  relative  to  cash  runway  and  achieved 
revenue  targets.  As  noted,  2020  saw  a  successful  leadership  transition  and  implementation  of  
refreshed organisational culture across Orchard. 

Additional achievements and considerations 
Further to the stated corporate goals as approved by the Board for 2020, the Company also achieved 
a number of  incremental accomplishments in relation to the product pipeline and corporate activities. 
The Compensation Committee considered these in making the final bonus decisions for 2020. 

Achievements included PRIME designation for OTL-203 (MPS-I), nine accepted abstracts at the 
WORLD symposium (presented in February 2021) and filed patent applications for proprietary HAE 
and FTD programs.

In evaluating the Company’s performance the Committee noted the significant challenges that the 
business has overcome during the year. These include, but not limited to, the leadership changes 
and transition of  CEO from Mr Rothera to Dr Gaspar, and staffing changes in relation to our site in 
Menlo Park, California. 

Additionally, the Committee commends the Company’s adaptability and management’s leadership 
in operating remotely as a result of  the COVID-19 pandemic. 

Delivery of  the bonus 
A Corporate Performance Score of  100% corresponding to a bonus outcome equivalent to 100% of  
target for the CEO. The Committee further resolved to deliver 50% of  this bonus in cash and 50% as 
a share option equity award.  

An award of  additional options was then granted to Dr Gaspar in February 2021. This was consistent 
with bonuses for Orchard’s Executive Leadership Team. The number of  share options granted to 
executives was determined based on the remaining value of  the bonus (ie - 50%) and the fair value 
of  the share options. The share options vest over a one-year period on a monthly basis. 

The Committee notes that the cash saving made by the Company as a result of  this decision was 
used as additional funding to the available employee bonus pool. 

The table below sets forth the 2020 annual base salaries, target annual cash bonus and, the 2020 
annual cash bonus earned by Dr Gaspar.

calculated as the Black Scholes value. 
The fair value on date of  grant for the PSU is based on the market price on the date of  grant. None of  the strategic 
performance conditions, as described below, have been deemed probable and the fair value is considered nil at

The chart below shows the Company’s Total Shareholder Return (TSR) performance compared with 
that of  the NASDAQ Biotechnology Index over the period from the date of  the Company’s admission

investment obtained from holding a company’s shares over a period. It includes dividends paid, the 
change in the capital value of  the shares and any other payments made to or by shareholders within 
the period.

Benefits and pension 
In 2020, Executive Directors are eligible for the same benefits (such as health insurance and pension) 
as  provided  to  all  employees  in  the  jurisdiction  in  which  they  reside.  Pension  contributions  for 
Executive Directors are up to 6% of  base salary which may be taken as a cash allowance. 6% is the 
rate provided to all employees in the UK and therefore representative of  the workforce rate. 

Annual Bonus 
The CEO will be entitled to a target bonus of  60% of  base salary, with the maximum payout up to 
150% of  target bonus (90% salary). 

Following the Compensation Committee's decision to only pay 50% of  the 2020 annual bonus in cash, 
an additional award of  55,006 options was made on 1 February 2021. These options vest on a monthly 
basis over 12 months from the date of  grant. 

These 2021 targets and maximum have been set within the overall Directors’ Remuneration Policy. 
Unless otherwise determined by the Compensation Committee, the bonus will be paid in cash and 
subject to the achievement of  a number of  strategic objectives determined by the Committee. 

Specific targets are commercially sensitive and therefore are not disclosed in advance. However, full 
details of  the targets and performance against them will be disclosed when they are no longer 
considered commercially sensitive. 

Share Option Incentive Plan (SOIP) 
Annual award of  share options 
In February 2021 as part of  the annual compensation package, the CEO was granted 850,000 share 
options in the Company at an exercise price of  $5.98, based on the closing price of  the Company’s 
ADSs on the Nasdaq Global Select Market on 1 February 2021. 

Following the Compensation Committee’s decision to only pay 50% of  the annual bonus in cash, an 
additional award of  55,006 options was made on 1 February 2021. 

                                                                                                                                                       Fair

At  the  date  of   this  report,  there  is  no  intention  to  make  any  further  awards  under  the  SOIP  to 
any  Directors.  Any  awards  made  during  the  year  will  be  disclosed  in  the  relevant  Directors’

1. COMPANY ACCOUNTING POLICIES 
BASIS OF PRESENTATION AND ACCOUNTING PRINCIPLES 
Orchard Therapeutics plc (the “Company”) and its subsidiaries (the “Group” or “Orchard”) is a global 
gene therapy leader dedicated to transforming the lives of  people affected by rare diseases through 
the development of  innovative, potentially curative gene therapies. The Groups’s ex vivo autologous 
gene  therapy  approach  utilizes  genetically-modified  blood  stem  cells  and  seeks  to  correct  the 
underlying cause of  disease in a single administration. The Group is advancing seven clinical-stage 
programs across multiple therapeutic areas, including inherited neurometabolic disorders, primary 
immune  deficiencies  and  blood  disorders,  where  the  disease  burden  on  children,  families  and 
caregivers is immense and current treatment options are limited or do not exist. 

The Company is a public limited company limited by shares, incorporated pursuant to the laws of  
England and Wales. Our registered office is located at 108 Cannon Street, London, EC4N 6EU, United 
Kingdom. Orchard Therapeutics plc was originally incorporated under the laws of  England and Wales 
in August 2018 to become a holding company for Orchard Therapeutics (Europe) Limited. 

The  financial  statements  have  been  prepared  in  accordance  with  United  Kingdom  Generally 
Accepted Accounting Practice (United Kingdom Accounting Standards, comprising FRS 102 “The 
Financial Reporting Standard applicable in the UK and Republic of  Ireland” and applicable law) and 
the Companies Act 2006. The financial statements are prepared under the historical cost convention. 

The Company is included in the Group financial statements of  Orchard Therapeutics plc, which are 
included within this Annual Report. 

The principal accounting policies applied in the preparation of  these financial statements are set out 
below. These policies have been consistently applied to all the years presented, unless otherwise 
stated. The Company has adopted FRS 102 in these financial statements. The Company has taken 
advantage  of   the  following  disclosure  exemptions  in  preparing  these  financial  statements,  as

The financial statements and related notes have been prepared and presented in U.S. Dollars. Unless 
otherwise noted, amounts are presented in USD thousands. 

INVESTMENTS 
The investment in the subsidiary arose on the reorganization of  the Group in 2018. The investment is 
recorded at cost less accumulated impairment losses. The cost is based on the directors’ estimated 
fair value of  Orchard Therapeutics (Europe) Limited having regard to the valuations that were available 
prior  to  the  IPO  in  November  2018,  additions  to  the  investment  associated  with  the  value  of  
share-based  payment  charges  associated  with  subsidiary  employees,  and  conversion  of  
intercompany debts to equity investments. Where at the year-end there is evidence of  impairment, 
the carrying value of  the investment is written down to its recoverable amount.

FOREIGN CURRENCY 
Foreign currency transactions are translated into the functional currency using the spot exchange 
rates at the dates of  the transactions. At each period end foreign currency monetary items are 
translated using the closing rate. Non-monetary items measured at historical cost are translated using 
the exchange rate at the date of  the transaction and non-monetary items measured at fair value are 
measured using the exchange rate when fair value was determined. 

GOING CONCERN 
The  financial  statements  have  been  prepared  on  a  going  concern  basis.  The  Directors  have 
considered the appropriateness of  the going concern basis in the Directors’ Report. In addition, the 
Parent Company acknowledges its responsibility to support its subsidiaries’ cash outflows for the 
foreseeable future. At 31 December 2020 the Group held cash, cash equivalents, and marketable 
securities of  $191.9 million, and the Parent Company held cash, cash equivalents, and marketable 
securities of  $134.6 million. The directors have prepared a forecast through 2022 and expect that 
cash, cash equivalents, and marketable securities on hand as of  December 31, 2020, together with 
the proceeds from the Private Placement of  $150.0 million of  ordinary shares that closed in February 
2021 (see Note 11, Subsequent Events), will be sufficient to fund operations and capital expenditure 
requirements for at least 12 months from the issuance of  these financial statements. The directors 
have considered the effect of  the COVID-19 pandemic on our forecast, and have determined it does 
not have an effect on our ability to operate as a going concern for at least 12 months from the issuance 
of  these financial statements. Therefore, the directors have at the time of  approving the financial 
statements, a reasonable expectation that the Group and Company have adequate resources to 
continue in operational existence for the foreseeable future and for a period of  at least 12 months 
from the date of  signing these financial statements. Accordingly, the Group and Company continues 
to adopt the going concern basis of  accounting in preparing these financial statements. 

SHARE-BASED PAYMENTS 
The financial effect of  awards by the Parent Company of  options and other equity-based awards 
over its equity shares to the employees of  subsidiary undertakings are recognized by the Parent 
Company in its individual financial statements. In particular, the Parent Company records a capital 
contribution to the subsidiary with a corresponding credit to the share compensation reserve. The 
expense associated with the equity-based awards is recognized in profit and loss for the subsidiary 
undertaking, and a corresponding capital contribution from the Parent Company in the subsidiary’s 
equity.  The  expense  associated  with  equity-based  awards  to  our  Non-executive  Directors  is 
recognized in profit and loss for the Parent Company. 

The  Parent  Company  recognizes  the  capital  contribution  associated  with  the  share-based 
compensation expense for awards granted to employees a straight-line basis over the requisite 
service period. The fair value of  each share option is estimated on the grant date using the Black 
Scholes option pricing model. 

CASH AND CASH EQUIVALENTS 
Cash and cash equivalents include cash in hand, deposits held at call with banks, and other short- 
term highly liquid investments with original maturities of  three months or less. 

DEBTORS 
Debtors are amounts due from other group companies for services performed in the ordinary course 
of  business. Debtors are recognised initially at fair value and subsequently measured at amortised 
cost using the effective interest method, less provision for impairment.

MARKETABLE SECURITIES AT FAIR VALUE THROUGH OTHER 
COMPREHENSIVE INCOME 
Marketable securities consist of  debt securities with original maturities of  greater than ninety days. 
The Company has classified its investments with maturities beyond one year as short term, based 
on their highly liquid nature and because such marketable securities represent the investment of  
cash that is available for current operations. The Company considers its investment portfolio of  
investments as available-for-sale. Accordingly, these investments are recorded at fair value, which is 
based on quoted market prices or other observable inputs. Unrealized gains and losses are recorded 
as a component of  other comprehensive income/(loss). Realized gains and losses are determined 
on a specific identification basis and are included in other income/(loss). Amortization and accretion 
of  discounts and premiums is also recorded in other income/(loss). 

CREDITORS – AMOUNTS FALLING DUE WITHIN ONE YEAR 
Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary 
course  of   business  from  suppliers.  Trade  creditors  are  recognised  initially  at  fair  value  and 
subsequently measured at amortised cost using the effective interest method. 

CREDITORS – AMOUNTS FALLING DUE AFTER MORE THAN ONE YEAR 
Creditors for amounts falling due after more than one year are notes payable, which are carried at 
amortised  cost,  using  the  effective  interest  method.  Issuance  costs  paid  to  establish  our  notes 
payable are recognized as on offset to the associated notes payable and amortised as interest 
expense over the term of  the loan. To the extent that portions of  our term loan facility are not drawn 
down, the issuance costs are deferred until the draw-down occurs. 

SHARE CAPITAL 
Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of  
share capital are shown as a deduction to equity, net of  tax. 

CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS 
The preparation of  financial statements in conformity with FRS102 requires the use of  accounting 
estimates and assumptions that affect the reported amounts of  assets and liabilities at the date of  
the financial statements. Although these estimates are based on management’s best knowledge of  
current events and actions, actual results ultimately may differ from those estimates. FRS102 requires 
management to exercise judgment in the process of  applying the accounting policies. 

Investment in subsidiary 
Management  perform  an  annual  impairment  assessment  of   the  investment  held  in  Orchard 
Therapeutics (Europe) Limited by the  Company. The valuation of  the subsidiary is derived from 
publicly available information, being the market capitalisation of  the group, as at the year end date, 
given that the future value of  the group is expected to be generated from the products and treatments 
which are being developed by the subsidiary companies. On the balance sheet date, where the 
market  capitalisation  of   the  group  as  a  whole  falls  below  the  carrying  value  of   the  investment, 
management will perform a fair value less cost to sell calculation and then consider whether an 
impairment of  the investment is required, and if  so, will write down the cost of  the investment to its 
recoverable amount, with an associated impairment charge recognised in the parent company profit 
and loss account. In the event the Group’s market capitalisation increases and the reasons for any 
impairment loss have ceased to apply, an impairment loss may be reversed in a subsequent period 
in the Parent Company profit and loss account, to the extent the carrying value would have been 
determined had no impairment loss been recognized for the investment in prior years.

Share-based payment cost of  $37.0 million in 2020 was recorded as a capital contribution from 
Orchard Therapeutics plc to Orchard Therapeutics (Europe) Limited and subsidiaries, as a capital 
injection in the Company’s Balance Sheet. 

On 23 July 2020 and 10 December 2020, the Company received 100,000 and 30,000 £0.00001 
ordinary shares respectively in Orchard Therapeutics (Europe) Limited in exchange for a total of  
$190.6 million of  intercompany debt due to the Company. 

The Parent Company performed an impairment analysis on a fair value less cost to sell basis, whereby 
the Parent Company used the market capitalisation of  the Group as the approximate fair value and 
the  cost  to  sell  and  control  premium  were  deemed  to  be  negligible.  The  carrying  value  of   the 
investment exceeded the fair value less cost to sell of  the investment as at 31 December 2020, and 
the Parent Company concluded that the investment was impaired by $792.8 million (2019: $nil). If  
the market capitalisation of  the group increases subsequent to the year end, then all or a portion of  
this impairment charge could be reversed in future years.

7. CREDITORS – amounts falling due after more than one year 
In May 2019, as amended in April 2020, the Company entered into a senior term facilities agreement 
(the “Credit Facility”) with MidCap Financial (Ireland) Limited (“MidCap Financial”), as agent, and 
additional lenders from time to time (together with MidCap Financial, the “Lenders”), to borrow up to 
$75.0 million in term loans in $25 million increments. To date, the Company has borrowed $25.0 million 
under an initial term loan. The remaining $50.0 million under the Credit Facility may be drawn down 
in the form of  a second and third term loan at the Company’s discretion and upon achievement of  
certain regulatory milestones and maintenance of  $100 million and $125 million in cash and cash 
equivalent investments, respectively. The second term loan of  $25.0 million is available between 1 July 
2020 and 31 March 2021. The third term loan of  $25.0 million is available between 1 July 2020 and 
30 September 2021. As of  31 December 2020, the Company had met the criteria to draw down the 
second  and  third  term  loans  totaling  $50.0  million,  but  these  have  not  been  drawn  down  as  at 
31 December 2020. 

The term loans under the Credit Facility will terminate in May 2024. Each term loan under the Credit 
Facility bears interest at an annual rate equal to 6% plus LIBOR. The Company is required to make 
interest-only payments on the term loan for all payment dates prior to 24 months following the date 
of  the Credit Facility, unless the third tranche is drawn, in which case the Company is required to 
make interest-only payments for all payment dates prior to 36 months following the date of  the Credit 
Facility. The term loans under the Credit Facility will begin amortizing on either the 24-month or the 
36-month anniversary of  the Credit Facility (as applicable), with equal monthly payments of  principal 
plus interest to be made by the Company to the Lenders in consecutive monthly installments until 
the Loan Maturity Date. In addition, a final payment of  4.5% is due upon termination. The Company 
accrues the final payment amount of  $1.1 million associated with the first term loan, to outstanding 
debt by charges to interest expense using the effective-interest method from the date of  issuance 
through the maturity date. 

As of  31 December 2020 and 2019, bank loans consist of  the following: 

                                                                                                                                                   2020                            2019

Notes to Consolidated Financial Statements 

1. Nature of Business and Basis of Presentation  

Orchard Therapeutics plc (the “Company”) is a global gene therapy company dedicated to transforming the lives of 
people affected by rare diseases through the development of innovative, potentially curative gene therapies. The 
Company’s ex vivo autologous hematopoietic stem cell (“HSC”) gene therapy approach utilizes genetically modified 
blood stem cells and seeks to correct the underlying cause of disease in a single administration. The Company’s 
gene therapy product candidate pipeline spans multiple therapeutic areas where the disease burden on children, 
families and caregivers is immense and current treatment options are limited or do not exist. 

The Company is a public limited company incorporated pursuant to the laws of England and Wales. The Company 
has American Depositary Shares (“ADSs”) registered with the U.S. Securities and Exchange Commission (the 
“SEC”) and has been listed on the Nasdaq Global Select Market since October 31, 2018. The Company’s ADSs 
each represent one ordinary share of the Company. 

In December 2020, the Company received full, or standard, marketing authorization from the European Commission 
for Libmeldy™ (autologous CD34+ cell enriched population that contains hematopoietic stem and progenitor cells 
transduced ex vivo using a lentiviral vector encoding the human arylsulfatase-A (ARSA) gene), for the treatment of 
early onset metchromatic leukodystrophy (“MLD”), characterized by biallelic mutations in the arylsulfatase-
A (ARSA) gene leading to a reduction of the ARSA enzymatic activity in children with (i) late infantile or early 
juvenile forms, without clinical manifestations of the disease, or (ii) the early juvenile form, with early clinical 
manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive 
decline. 

The Company is subject to risks and uncertainties common to development-stage companies in the biotechnology 
industry. There can be no assurance that the Company’s research and development will be successfully completed, 
that adequate protection for the Company’s technology will be obtained, that any products developed will obtain 
necessary government regulatory approval or that any products, if approved, will be commercially viable. The 
Company operates in an environment of rapid technological innovation and substantial competition from 
pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its 
employees, consultants and service providers. Even if the Company’s product development efforts are successful in 
gaining regulatory approval, it is uncertain when, if ever, the Company will realize significant revenue from product 
sales.  

The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, 
realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. Through 
December 31, 2020, the Company funded its operations primarily with proceeds from the sale of convertible 
preferred shares, and ADSs in the IPO and follow-on offering. The Company has incurred recurring losses since its 
inception, including net losses of $152.0 million and $163.4 million for the years ended December 31, 2020 and 
2019, respectively. As of December 31, 2020, the Company had an accumulated deficit of $605.6 million. The 
Company expects to continue to generate operating losses for the foreseeable future. The Company expects that its 
cash, cash equivalents, and marketable securities on hand as of December 31, 2020 of $191.9 million, together with 
the proceeds from the Private Placement of $150.0 million of ordinary shares that closed in February 2021 (see Note 
20), will be sufficient to fund its operations and capital expenditure requirements for at least the next twelve months. 
The Company will seek additional funding through private or public equity financings, debt financings, 
collaborations, strategic alliances and marketing, distribution or licensing arrangements. The Company may not be 
able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations 
or other arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company's 
stockholders. The future viability of the Company is dependent on its ability to raise additional capital to finance its 
operations. If the Company is unable to obtain funding, the Company will be forced to delay, reduce or eliminate 
some or all of its research and development programs, product portfolio expansion or commercialization efforts, 
which could adversely affect its business prospects, or the Company may be unable to continue operations. 
Although management continues to pursue these plans, there is no assurance that the Company will be successful in 
obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

Basis of presentation  

The accompanying consolidated financial statements have been prepared in accordance with accounting principles 
generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of the Company and its 
wholly owned subsidiaries, after elimination of all intercompany accounts and transactions.  

Deferred income taxes in the consolidated statement of cash flows for the year-ended December 31, 2019 previously 
included in changes in prepaid expenses and other assets has been presented as a separate line item as a non-cash 
item within adjustments to reconcile net loss to net cash used in operating activities in the consolidated statement of 
cash flows to conform to current period presentation. 

Amounts reported are computed based on thousands, except percentages, per share amounts or as otherwise noted. 
As a result, certain totals may not sum due to rounding. 

UK Companies Act 2006 additional disclosures  

Additional disclosures required for the group financial statements under the Companies Act 2006 are shown on page 
3 of the Annual Report and in the auditable part of the Directors' Remuneration Report on pages 109-115.   

2. Summary of Significant Accounting Policies  

Principles of consolidation 

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned 
subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. 

Use of estimates  

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make 
estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent 
assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and 
expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated 
financial statements include, but are not limited to, the accrual for research and development expenses, the research 
and development tax credit receivable, share-based compensation, operating lease assets and liabilities, and income 
taxes. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. The future 
developments of the COVID-19 pandemic also may directly or indirectly impact the Company’s business 
include quarantines, border closures, increased border controls, travel restrictions, shelter-in-place orders and 
shutdowns, business closures, cancellations of public gatherings and other measures.  Actual results could differ 
from the Company’s estimates.  

Concentration of credit risk  

The Company has no significant off-balance sheet risk, such as foreign currency contracts, options contracts, or 
other foreign hedging arrangements. Financial instruments that potentially expose the Company to concentrations of 
credit risk consist primarily of cash, cash equivalents, marketable securities, and receivables. The Company 
maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its 
cash in financial institutions that it believes have high credit quality and has not experienced any losses on such 
accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with 
commercial banking relationships or entities for which it has a receivable.  

Foreign currency 

The financial statements of the Company’s subsidiaries with functional currencies other than the U.S. dollar are 
translated into U.S. dollars using period-end exchange rates for assets and liabilities, historical exchange rates for 
stockholders’ equity and weighted average exchange rates for operating results. Translation gains and losses are 
included in accumulated other comprehensive income (loss) in shareholders’ equity. Foreign currency transaction 
gains and losses are included in other income (expense), net in the results of operations. The Company recorded 

F-6 

Orchard Therapeutics plc  137

 
 
 
 
 
 
 
 
realized and unrealized foreign currency transaction gains of $3.4 million, and $1.4 million for the years ended 
December 31, 2020 and 2019, respectively, which is included in other income (expense) in the statements of 
operations and comprehensive loss.  

Segment information 

The Company operates in a single segment, focusing on researching, developing and commercializing potentially 
curative gene therapies.  Consistent with its operational structure, its chief operating decision maker manages and 
allocates resources at a global, consolidated level. Therefore, results of the Company's operations are reported on a 
consolidated basis for purposes of segment reporting.  All material long-lived assets of the Company reside in the 
United States or United Kingdom. The Company had property and equipment of $3.7 million and $1.1 million 
located in the United Kingdom and United States, respectively, as of December 31, 2020. The Company had 
property and equipment of $2.6 million and $5.0 million located in the United Kingdom and United States, 
respectively, as of December 31, 2019. The Company had right-of-use assets in the United States and United 
Kingdom and European Union of $14.2 million and $15.6 million, respectively, as of December 31, 2020. The 
Company had right-of-use assets in the United States and United Kingdom and European Union of $15.7 million 
and $3.7 million, respectively, as of December 31, 2019. 

Cash and cash equivalents  

The Company considers all highly liquid investments purchased with original maturities of 90 days or less at the 
date of acquisition to be cash equivalents.  

Marketable securities 

Marketable securities consist of investments with original maturities greater than ninety days at the date of 
acquisition. The Company has classified its investments with maturities beyond one year as short term, based on 
their highly liquid nature and because such marketable securities represent the investment of cash that is available 
for current operations. The Company considers its investment portfolio of investments as available-for-
sale. Accordingly, these investments are recorded at fair value, which is based on quoted market prices or other 
observable inputs. Unrealized gains and losses are recorded as a component of other comprehensive income (loss). 
Realized gains and losses are determined on a specific identification basis and are included in other income (loss). 
Amortization and accretion of discounts and premiums is also recorded in other income (loss). 

When the fair value is below the amortized cost of the asset an estimate of expected credit losses is made, and is 
limited to the amount by which fair value is less than amortized cost. The credit-related impairment amount is 
recognized in net income; the remaining impairment amount and unrealized gains are reported as a component of 
accumulated other comprehensive income (loss) in shareholders’ equity. Credit losses are recognized through the 
use of an allowance for credit losses account and subsequent improvements in expected credit losses are recognized 
as a reversal of the allowance account. If the Company has the intent to sell the security or it is more likely than not 
that the Company will be required to sell the security prior to recovery of its amortized cost basis the allowance for 
credit loss is written off and the excess of the amortized cost basis of the asset over its fair value is recorded in the 
consolidated statements of operation. 

Restricted cash 

F-7 

138  Orchard Therapeutics plc 

 
 
 
 
Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual 
agreements are recorded as restricted cash on our consolidated balance sheet. The Company has an outstanding letter 
of credit for $3.0 million associated with a lease, and is required to hold this amount in a standalone bank account at 
December 31, 2020 and 2019. The Company is also contractually required to maintain a cash collateral account 
associated with corporate credit cards and other leases in the amount of $1.3 million at December 31, 2020 and 
2019.  

The Company includes the restricted cash balance in cash and cash equivalents when reconciling beginning-of-
period and end-of-period total amounts shown on the consolidated statements of cash flows. The following table 
provides a reconciliation of cash, cash equivalents, and restricted cash reported in the consolidated balance sheet that 
sum to the total of the amounts reported in the consolidated statement of cash flows:

Property and equipment  

Property and equipment are recorded at cost and depreciated or amortized using the straight-line method over the 
following estimated useful lives.  

Property and equipment: 
Lab equipment 
Leasehold improvements 
Furniture and fixtures 
Office and computer equipment 

   Estimated useful  life

   3-5 years 

Repairs and maintenance expenditures, which are not considered improvements and do not extend the useful life of 
property and equipment, are expensed as incurred. Upon retirement or sale, the cost of assets disposed of and the 
related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the 
statement of operations and other comprehensive loss.  

Impairment of long-lived assets  

Long-lived assets consist of property and equipment and operating lease right-of-use assets. Long-lived assets to be 
held and used are tested for recoverability whenever events or changes in business circumstances indicate that the 
carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to 
perform an impairment review include significant underperformance of the business in relation to expectations, 
significant negative industry or economic trends and significant changes or planned changes in the use of the assets. 
If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares 
forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset 
group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows 
expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be 

F-8 

Orchard Therapeutics plc  139

 
 
 
  
  
  
  
  
    
  
     
   
 
 
 
 
based on the excess of the carrying value of the impaired asset group over its fair value, as determined in accordance 
with the related accounting literature.  

Research and development costs  

Research and development costs are expensed as incurred. Research and development expenses consist of costs 
incurred in performing research and development activities, including salaries, share-based compensation and 
benefits, facilities costs, depreciation, third-party license fees, certain milestone payments, and external costs of 
outside vendors engaged to conduct clinical development activities and clinical trials, as well as costs to develop a 
manufacturing process, perform analytical testing and manufacture clinical trial materials. Non-refundable 
prepayments for goods or services that will be used or rendered for future research and development activities are 
recorded as prepaid expenses. Such amounts are recognized as an expense as the goods are delivered or the related 
services are performed, or until it is no longer expected that the goods will be delivered, or the services rendered. In 
addition, funding from research grants is recognized as an offset to research and development expense on the basis 
of costs incurred on the research program. Royalties to third parties associated with our research grants will be 
accrued when they become probable. 

Research contract costs and accruals  

The Company has entered into various research and development contracts. These agreements are cancelable, and 
related costs are recorded as research and development expenses as incurred. When billing terms under these 
contracts do not coincide with the timing of when the work is performed, the Company is required to make estimates 
of outstanding obligations as of period end to those third parties.  Any accrual estimates are based on a number of 
factors, including the Company’s knowledge of the progress towards completion of the research and development 
activities, invoicing to date under the contracts, communication from the research institution or other companies of 
any actual costs incurred during the period that have not yet been invoiced, and the costs included in the contracts. 
Significant judgments and estimates may be made in determining the accrued balances at the end of any reporting 
period. Actual results could differ from the estimates made by the Company. The historical accrual estimates made 
by the Company have not been materially different from the actual costs. 

Share-based compensation  

The Company measures all stock options and other stock-based awards granted to employees at fair value on the 
date of grant. The Company uses the Black-Scholes option-pricing model in the valuation of its stock options. The 
fair value of performance-based share awards and restricted stock units is based on the fair value of the stock on the 
date of grant. The Company uses the Monte-Carlo model in order to calculate the fair value of the market-based 
awards. The fair value of options is recognized as stock-based compensation expense over the requisite service 
period, which is generally the vesting period of the respective award. The Company accounts for stock-based 
compensation expense related to forfeitures as the forfeitures occur. The straight-line method of expense recognition 
is applied to all awards with service-based and market-based conditions. The Company records stock-based 
compensation expense related to performance-based awards when the performance-based targets are probable of 
being achieved. The Company classifies stock-based compensation expense in the consolidated statements of 
operations in the same manner in which the award recipient’s payroll costs are classified. 

Comprehensive loss  

Comprehensive loss is composed of net loss and other comprehensive income (loss). Other comprehensive income 
(loss) consists of unrealized gains and losses on marketable debt securities and foreign currency translation.   

Leases 

The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent a right 
to use an underlying asset for the lease term and operating lease liabilities represent an obligation to make lease 
payments arising from the lease. Operating lease liabilities with a term greater than one year and their corresponding 
right-of-use assets are recognized on the balance sheet at the commencement date of the lease based on the present 
value of lease payments over the expected lease term. Certain adjustments to the right-of-use asset may be required

for items such as initial direct costs paid or incentives received. The Company made an accounting policy election to 
not record a right-of-use asset or lease liability for leases with a term of one year or less. To date, the Company has 
not identified any material short-term leases, either individually or in the aggregate. 

As the Company’s leases do not provide an implicit rate, the Company utilized the appropriate incremental 
borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term as the lease an 
amount equal to the lease payments in a similar economic environment. The Company estimated the incremental 
borrowing rate based on the Company’s currently outstanding credit facility as inputs to the analysis to calculate a 
spread, adjusted for factors that reflect the profile of secured borrowing over the expected term of the lease. 

The components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-
lease components (e.g., common area maintenance, utilities, performance of manufacturing services, purchase of 
inventory, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed contract consideration 
(including any related to non-components) must be allocated based on fair values to the lease components and non-
lease components. Although separation of lease and non-lease components is required, certain practical expedients 
are available to entities. Entities electing the practical expedient would not separate lease and non-lease components. 
Rather, they would account for each lease component and the related non-lease component together as a single 
component. The Company has elected not to apply the practical expedient and with respect to its lease of 
manufacturing space at a contract manufacturing organization, the Company has allocated the consideration between 
the lease and non-lease components of the contract based on the respective fair values of the lease and non-lease 
components. The Company calculated the fair value of the lease and non-lease components using financial 
information readily available as part of its master services arrangement and other representative data indicative of 
fair value. 

The Company accounts for sublease income on a straight-line basis over the respective lease period and records an 
unbilled rent receivable for sublease income incurred but not yet paid. The Company periodically performs a 
collectability assessment associated with any unbilled rent receivables. The Company recognizes the sublease 
income as a reduction to the related operating expense associated with the head lease.

Strimvelis loss provision 

As part of the GSK transaction, the Company is required to maintain commercial availability of Strimvelis in the 
European Union until such time that an alternative gene therapy is available (Note 13). Strimvelis is not currently 
expected to generate sufficient cash flows to overcome the costs of maintaining the product and certain regulatory 
commitments; therefore, the Company initially recorded a liability associated with the loss contract of $18.4 million 
as part of the GSK transaction in 2018. The Company recognizes the amortization of the loss provision on a 
diminishing balance basis based on the actual net loss incurred associated with Strimvelis and the expected future 
net losses to be generated until such time as Strimvelis is no longer commercially available. The amortization of the 
provision is recorded as a credit to research and development expense. We have made an estimate of the expected 
future losses associated with Strimvelis and adjust this estimate as facts and circumstances change regarding the 
commercial availability and costs of maintaining and selling Strimvelis. The Company does not update the accrued 
loss provision for any subsequent adjustment of the future losses, however, the timing of recognizing the 
amortization of what was originally recorded is adjusted for updates to estimates of potential future losses. The 
Company paused treating new patients with Strimvelis in October 2020 upon learning that a patient treated with the 
drug in 2016 under a compassionate use program was diagnosed with lymphoid T cell leukemia, a known risk factor 
for gammaretroviral vector-based gene therapy. The EMA’s Committee for Medicinal Products for Human Use, or 
CHMP, reviewed the updated risk-benefit assessment of Strimvelis as part of its ongoing MAA renewal procedure, 
concluded that the risk-benefit balance remains favorable and recommended in February 2021 that the marketing 
authorization for Strimvelis be renewed for five years, allowing marketing of Strimvelis to resume. The Company 
will continue to evaluate its future estimates for amortization of the Strimvelis loss provision. The following table 
below outlines the changes to the Strimvelis loss provision for the periods ended December 31, 2020 and 2019:

United Kingdom Research and development income tax credits  

As a company that carries out research and development activities, the Company is able to submit tax credit claims 
from two UK research and development tax relief programs, the Small and Medium-sized Enterprises research and 
development tax credit (“SME”) program and the Research and Development Expenditure Credit (“RDEC”) 
program depending on eligibility. Qualifying expenditures largely comprise employment costs for research staff, 
consumables and certain internal overhead costs incurred as part of research projects for which the Company does 
not receive income. 

Each reporting period, management evaluates which tax relief programs the Company is expected to be eligible for 
and records a reduction to research and development expense for the portion of the expense that it expects to qualify 
under the programs, that it plans to submit a claim for, and it has reasonable assurance that the amount will 
ultimately be realized. Based on criteria established by HM Revenue and Customs (“HMRC”), management of the 
Company expects a proportion of expenditures being carried in relation to its pipeline research, clinical trials 
management and manufacturing development activities to be eligible for the research and development tax relief 
programs for the year ended December 31, 2020. The Company has qualified under the more favorable SME regime 
for the year ended December 31, 2019 and expects to qualify under the SME regime for the year ending December 
31, 2020.

The RDEC and SME credits are not dependent on the Company generating future taxable income or on the ongoing 
tax status or tax position of the Company. The Company has assessed its research and development activities and 
expenditures to determine whether the nature of the activities and expenditures will qualify for credit under the tax 
relief programs and whether the claims will ultimately be realized based on the allowable reimbursable expense 
criteria established by the UK government which are subject to interpretation. At each period end, the Company 
estimates the reimbursement available to the Company based on available information at the time. 

The Company recognizes credits from the research and development incentives when the relevant expenditure has 
been incurred and there is reasonable assurance that the reimbursement will be received. Such credits are accounted 
for as reductions in research and development expense. The following table outlines the changes to the research and 
development tax credit receivable, including amount recognized as an offset to research and development expense 
during the years ended December 31, 2020 and 2019:

During the year ended December 31, 2020, the Company recorded $4.8 million of additional tax credits related to a 
change in estimate associated with its UK research and development tax credit receivable claim for fiscal year 2019. 
The change in estimate was based on the results of a tax credit analysis associated with the Company’s qualified 
projects and research and development expenditures completed during the third quarter to finalize the 2019 UK tax 
return.  

As of December 31, 2020, the Company’s tax credit receivable from the UK was $17.3 million, all of which was 
classified as current. As of December 31, 2019, the Company’s tax incentive receivable from the UK was $28.6 
million, of which $14.9 million was classified as current and $13.7 million was classified as non-current. As of 
December 31, 2020, the Company has received all of its 2016-2019 tax credit claims from HMRC.  

Income taxes  

The Company is primarily subject to corporation taxes in the United Kingdom and the United States. The 
calculation of the Company’s tax provision involves the application of both United Kingdom and United States tax 
law and requires judgement and estimates.  

The Company accounts for income taxes in accordance with ASC Topic 740, Accounting for Income Taxes, which 
provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and 
liabilities for the expected future tax consequences of events that have been included in the financial statements or 
tax returns. The Company determines its deferred tax assets and liabilities based on differences between financial 
reporting and tax bases of assets and liabilities, which are measured using the enacted tax rates and laws that will be 
in effect when the differences are expected to reverse. Valuation allowances are provided if, based upon the weight 
of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized.  

The Company accounts for uncertainty in income taxes by applying a two-step process to determine the amount of 
tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be 
sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to 
be sustained, the tax position is then assessed as the amount of benefit to recognize in the consolidated financial 
statements. The amount of benefits that may be used is the largest amount that has a greater than 50% likelihood of 
being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax 
reserves, or unrecognized tax benefits, that are considered appropriate, as well as the related net interest and 
penalties.

Product sales 

The Company’s product sales of Strimvelis are currently distributed exclusively at the San Raffaele Hospital in 
Milan, Italy. San Raffaele Hospital will purchase and pay for Strimvelis and submit a claim to the payer. The 
Company’s contracted sales with San Raffaele Hospital contain a single performance obligation and the Company 
recognizes revenue from product sales when the Company has satisfied its performance obligation by transferring 
control of Strimvelis to San Raffaele Hospital. Control of the product generally transfers upon the completion of the 
scheduled Strimvelis treatment. The Company’s product sales represent total net product sales of Strimvelis. The 
Company evaluated the variable consideration under Accounting Standards Codification (ASC) 606, Revenue from 
Contracts with Customers, and there is currently no variable consideration included in the transaction price for 
Strimvelis. Costs to manufacture and deliver the product and those associated with administering the therapy are 
included in cost of product sales. As the product is sold in direct relation to a scheduled treatment, the Company 
estimates that there is limited risk of product return, including the risk of product expiration. 

Net income (loss) per share  

Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of 
ordinary shares outstanding for the period. Diluted net income (loss) is computed by adjusting net income (loss) 
based on the potential impact of dilutive securities. Diluted net income (loss) per share is computed by dividing the 
diluted net income (loss) by the weighted average number of ordinary shares outstanding for the period, including 
potential dilutive ordinary shares. For purpose of this calculation, outstanding options and unvested restricted shares 
are considered potential dilutive ordinary shares.  Since the Company was in a loss position for all periods 
presented, basic net loss per share is the same as diluted net loss per share for all periods as the inclusion of all 
potential ordinary share equivalents outstanding would have been anti-dilutive.  

The following securities, presented based on amounts outstanding at each period end, are considered to be ordinary 
share equivalents, but were not included in the computation of diluted net loss per ordinary share because to do so 
would have been anti-dilutive:

Recent accounting pronouncements 

In February 2016 and July 2018, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), ASU 
2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”) and ASU 2018-11, Leases (Topic 842) 
Targeted Improvements (“ASU 2018-11”), which sets out the principles for the recognition, measurement, 
presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU 2016-02, ASU 
2018-10 and ASU 2018-11, supersede the lease guidance under FASB ASC Topic 840, Leases, resulting in the 
creation of FASB ASC Topic 842, Leases (“ASC 842”). The new standard requires that all lessees (i) recognize, on 
the balance sheet, liabilities to remit lease payments and right-of-use assets, representing the right to use the 
underlying asset for the lease term for both finance and operating leases, and (ii) disclose qualitative and quantitative 
information about its leasing arrangements. 

ASC 842 became effective for the Company in 2019. The Company adopted ASC 842 using the modified 
retrospective approach with an effective date of January 1, 2019 for leases that existed on that date. Prior period 
results continue to be presented under ASC 840 based on the accounting standards originally in effect for such 
periods. This standard provides a number of optional practical expedients in transition. The Company applied the 
package of practical expedients to leases that commenced prior to the effective date, whereby it elected not to 
reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for 
any expired or existing leases; and (iii) initial direct costs for any existing leases. The Company elected the short-
term lease recognition exemption for all leases that qualify, where a right-of-use asset or lease liability will not be 
recognized for short term leases that have terms of one year or less.

The operating lease right-of-use assets and corresponding liabilities relate to existing facility operating leases in 
London, UK, Boston, Massachusetts, and the San Francisco Bay Area, California, as well as an embedded operating 
lease for research and development space at a contract manufacturing organization. The most significant effects of 
adoption were the recognition of material new right-of-use assets and corresponding liabilities on its consolidated 
balance sheet related to its existing facility operating leases (see Note 10). The adoption of this standard had a 
material impact on the Company’s financial position but did not significantly affect the Company’s results of 
operations or cash flows.  

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement 
of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires entities to record expected credit losses 
for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current 
estimate of credit losses expected to be incurred. For available-for-sale debt securities in unrealized loss positions, 
the new standard requires allowances to be recorded instead of reducing the amortized cost of the investment. The 
new standard became effective for us on January 1, 2020. This guidance did not have a significant impact on the 
Company’s consolidated financial statements and related disclosures. The Company has a UK research and 
development tax credit receivable and trade receivables that are subject to this guidance. The Company has assessed 
whether it believes there is a current estimate of credit loss expected to be recorded for these receivables and 
concluded that any amount would not be significant and therefore the Company has not recorded any credit loss 
allowance for these receivables. 

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), 
which removes certain exceptions to the general principles in Topic 740 – Income Taxes and improves consistent 
application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This 
ASU is effective for the Company beginning January 1, 2021 and interim periods within that year, with early 
adoption permitted. The Company is currently evaluating the effect of adopting this new accounting guidance. 

3. Fair Value Measurements and Marketable Securities 

The following tables present information about the Company’s financial assets that have been measured at fair value 
as of December 31, 2020 and 2019 and indicate the fair value of the hierarchy of the valuation inputs utilized to 
determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in 
active markets for identical assets or liabilities. Fair value determined by Level 2 inputs utilize observable inputs 
other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted market prices in markets that 
are not active or other inputs that are observable or can be corroborated by observable market data for substantially 
the full term of the related assets or liabilities. Fair values determined by Level 3 inputs are unobservable data points 
for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. 
During the years ended December 31, 2020 and 2019, there were no transfers between Level 1 and Level 2 financial 
assets.

4. Revenue Recognition 

During the years ended December 31, 2020 and 2019 the Company recorded sales for one commercial-stage 
therapy, Strimvelis, for the treatment of ADA-SCID. Strimvelis is currently distributed exclusively at the San 
Raffaele Hospital in Milan, Italy. San Raffaele Hospital will purchase and pay for Strimvelis and submit a claim to 
the payer. The Company’s contracted sales with San Raffaele Hospital contain a single performance obligation and 
the Company recognizes revenue from product sales when the Company has satisfied its performance obligation by 
transferring control of Strimvelis to San Raffaele Hospital. Control of the product generally transfers upon the 
completion of the scheduled Strimvelis treatment. The Company’s product sales represent total net product sales of 
Strimvelis. The Company evaluated the variable consideration under Accounting Standards Codification (ASC) 
606, Revenue from Contracts with Customers, and there is currently no variable consideration included in the 
transaction price for Strimvelis. Costs to manufacture and deliver the product and those associated with 
administering the therapy are included in cost of product sales. As the product is sold in direct relation to a 
scheduled treatment, the Company estimates that there is limited risk of product return, including the risk of product 
expiration. 

Costs to manufacture the product and those associated with administering the therapy are included in cost of product 
sales. As the product is sold in direct relation to a scheduled treatment, the Company estimates that there is minimal 
risk of product return, including the risk of product expiration.  

Payment terms and conditions generally require payment for Strimvelis sales within 60 days of treatment. Strimvelis 
is currently distributed exclusively at the San Raffaele Hospital, and there is currently no variable consideration 
included in the transaction price of Strimvelis. 

5. Prepaid expenses and other current assets 

Prepaid expenses and other current assets consist of the following: 

Prepaid external research and development expenses 
Inventories

In May 2020, the Company committed to a new strategic plan and restructuring intended to enable the Company to 
advance its corporate strategy while reducing overall operating expenses, including ceasing construction and build-
out of its Fremont, California manufacturing facility, closing its office in Menlo Park, California, reducing its 
workforce by approximately 25% across the Company, eliminating a number of future positions expected to be 
recruited in 2020 and 2021, reducing its investment in the future development for certain programs, and other cost-
saving measures (collectively, the “Restructuring”). The workforce reductions took place primarily during the 
second and third quarters of 2020, and concluded in the fourth quarter of 2020. 

Cash restructuring charges 

Accrued restructuring and severance costs are included in Accrued expenses and other current liabilities in the

The Company assessed the Fremont construction-in-process for impairment in May 2020 upon the Restructuring. 
The construction-in-process related to design costs, and was determined to have no potential future value, and an 
impairment charge of $2.3 million was taken for the full value of the construction-in-process asset. 

The Company assessed the Fremont ROU asset for impairment in May 2020 upon the Restructuring when the 
carrying value of the asset was $13.8 million. The Fremont ROU asset represented the asset group for the 
impairment assessment. Upon failing the first step of the long-lived asset impairment model where the undiscounted 
cash flows were less than the carrying value of the Fremont ROU asset, the Company performed the second step by 
comparing the fair value of the Fremont ROU asset to its carrying value. The fair value of the Fremont ROU asset is 
a non-recurring fair value measurement that was measured using a probability-weighted discounted cash flow 
approach, which estimated the present value of potential sublease income to be generated by the facility, less costs 
incurred to sublease the facility. The significant assumptions inherent in estimating the various probability weighted 
scenarios included the undiscounted forecasted sublease income less costs incurred, which included assumptions of 
the expected income and timing of entering into a future sublease, and a market-participant discount rate that reflects 
a potential discount rate. The Company selected the assumptions used in the fair value estimate using current market 
data associated with the potential sublease income and market participant discount rates. The undiscounted cash 
flows utilized in the fair value estimate ranged from $11.7 million to $19.1 million to be generated over the 
remainder of the lease term. The market-participant discount rate utilized in the fair value estimate was 4.6%. These 
assumptions represent level 3 inputs of the fair value hierarchy (see Note 3). 

As of the assessment date, the fair value of the Fremont ROU asset was $11.2 million, and the Company recorded a 
$2.6 million impairment charge related to the asset. The remaining carrying value of the Fremont ROU asset is 
being amortized over the remaining lease term on a straight-line basis. In December 2020, the Company executed a 
sublease for the Fremont manufacturing facility with an unrelated third-party for the remaining lease term (see Note 
10). No further impairment was necessary as a result of the sublease. The occurrence of a triggering event for the 
Fremont ROU asset in future periods could result in additional impairment charges if the estimated fair value of the 
asset is determined to be lower than the carrying value. 

10. Leases 

Operating leases 
In November 2017 and January 2019, the Company entered into lease agreements for office and laboratory space in 
Menlo Park, California, United States. The leases terminated in December 2020. The combined annual rental 
payments, including variable payments, under both leases with the same landlord were $1.9 million in 2020. The 
Company was provided with one month of free rent in connection with the first lease. The lease agreement included 
annual rent escalation provisions. 

In January 2018 and December 2018, the Company entered into lease agreements for office space in London, United 
Kingdom, both of which terminate in January 2023. The combined annual rental payments, including variable 
payments, under the lease agreements were $1.7 million in 2020.  

In March 2018, the Company entered into a lease agreement for office space in Boston, Massachusetts, United 
States, which terminates in September 2022. The annual rental payments, including variable payments, were $0.4 
million in 2020. The lease agreement includes annual rent escalation provisions.

In July 2019, the Company entered into a lease agreement for office space in Boston, Massachusetts, United States, 
which commences for accounting purposes in January 2020. The lease terminates in September 2026. The annual 
rental payments, including variable payments, were $0.9 million in 2020. The lease agreement includes annual rent 
escalation provisions. 

As of December 31, 2020, the carrying value of the operating lease right-of-use assets in Boston and London was 
$5.4 million and the lease liabilities was $5.7 million. 

Fremont operating lease and sublease agreements 

In December 2018, the Company leased manufacturing, laboratory, and office space in Fremont, California (the 
“Fremont facility” and the “Head Lease”) which terminates in May 2030. In May 2020, the Company committed to 
a restructuring plan (see Note 9) whereby we ceased construction and build-out of the Fremont facility. In December 
2020, the Company entered into a sublease agreement (the “Sublease”) with an unrelated third-party (the 
“subtenant”) whereby the Company subleased the entire Fremont facility to the subtenant. The Company accounts 
for the Head Lease and Sublease as two separate contracts. Both the Head Lease and Sublease were determined to 
be operating leases. 

The Head Lease annual rental payments, including variable payments, were $3.1 million in 2020. The Head Lease 
includes annual rent escalation provisions. The Company was provided with 8 months of free rent. Subject to the 
terms of the Head Lease agreement, the Company executed a $3.0 million letter of credit upon signing the lease, 
which may be reduced by 25% subject to reduction requirements specified therein. This amount is classified as 
restricted cash on the consolidated balance sheet.   

As of December 31, 2020, the carrying value of the Fremont Head Lease right-of-use asset was $10.5 million and 
the lease liability was $14.4 million related to the Fremont facility. The Head Lease provides for up to $5.3 million 
in tenant improvement allowances to be reimbursed to the Company by the landlord. These tenant improvement 
allowances have been included in the calculation of the operating lease liability and is currently expected to be 
received in 2021 and 2022. The Company continues to assess the expected receipt of the tenant improvement 
allowances any may remeasure the right-of-use asset and liability from time to time as facts and circumstances may 
change. 

The Sublease commenced in December 2020 and is in force for the remainder of the Head Lease term, through May 
2030. The Sublease provides for 12 months of free rent until December 2021. The sublease provides for an initial 
annual cash base rent of $2.1 million, with annual rent escalation provisions. The subtenant is also responsible for 
paying all operating expenses associated with the Head Lease. The Sublease also includes pass-through of up to $5.3 
million in tenant improvement allowances to the subtenant, subject to the Company being reimbursed for the 
allowances per the terms of the Head Lease. The Subtenant provided the Company with a $2.6 million security 
deposit, which may be converted to a letter of credit upon providing evidence of $2.6 million in construction 
expenditures. The Company accounts for the security deposit within other long-term liabilities. 

The Company has $8.1 million in an escrow account associated with construction on the Fremont facility, for which 
the Company has ceased construction and build-out. Subject to the terms of the Head Lease and reduction 
provisions, this amount may be returned to the Company upon qualifying construction expenditure, or will be 
returned in late 2022 (the “Sunset Date”) to the extent construction expenses have not been incurred. The Company 
deposited $10.0 million into the account in the first quarter of 2020 and has received $1.9 million in receipts from 
the escrow funds for costs incurred to date. Of the $8.1 million remaining in the escrow account, $1.6 million is 
classified within prepaid expenses and other current assets and $6.5 million is classified within other assets on the 
consolidated balance sheet based on the timing of when the Company expects funds to be returned from the escrow 
agent. Future receipts from the escrow deposit will be dependent upon the timing of the subtenant construction 
spend through the Sunset Date.

Embedded operating lease arrangement 

The Company is party to a manufacturing agreement for research and development and commercial production with 
AGC Biologics, S.p.A. (formerly MolMed S.p.A.) (“AGC”) pursuant to which AGC will develop, manufacture and 
supply certain viral vectors and conduct cell processing activities for certain Company development and commercial 
programs.  A manufacturing agreement with AGC was novated to the Company as part of the GSK Agreement (see 
Note 16).  On July 2, 2020 (the “Effective Date”), the Company entered into a new manufacturing and technology 
development master agreement with AGC (the “AGC Agreement”) which superseded the novated agreement.  

The Company determined that the AGC Agreement contains an embedded lease as it includes provision of 
manufacturing suites designated for the Company’s exclusive use during the term of the agreement. The AGC 
Agreement has an initial term of five years, beginning on the Effective Date and ending July 2, 2025. The agreement 
may be extended for an additional two years by mutual agreement of the Company and AGC. The AGC Agreement 
contains payments associated with lease and non-lease components. The annual rental payments associated with the 
lease that are considered a lease component amount to €2.7 million per contract year. The non-lease components of 
the agreement consist of minimum manufacturing purchase requirements and dedicated manufacturing and 
development services with an initial annual commitment of €10.2 million. 

As of December 31, 2020, the carrying value of the embedded operating lease right-of-use asset was $13.9 million 
and the lease liability was $13.1 million. The Company may terminate the AGC Agreement and the use of the 
exclusive manufacturing suites, with 12-months’ notice, and beginning no earlier than July 2, 2022. AGC may 
terminate the AGC Agreement with 24-months’ notice. The AGC Agreement provides for an option to reserve one 
additional exclusive manufacturing suite any time prior to January 1, 2022 for a one-time option fee plus annual 
rental fee. The AGC Agreement extends until July 2, 2025. 

Summary of all lease costs recognized under ASC 842 

Our facility leases described above generally contain customary provisions allowing the landlords to terminate the 
leases if we fail to remedy a breach of any of our obligations under any such lease within specified time periods, or 
upon our bankruptcy or insolvency. The leases do not include any restrictions or covenants that had to be accounted 
for under the lease guidance. The following table contains a summary of the lease-related costs recognized within 
operating expenses, and other information pertaining to the Company’s operating leases as of December 31, 2020

Fixed lease cost represents the ASC 842 rent expense associated with the amortization of our right-of-use assets and 
lease liabilities. Impairment of right-of-use assets relates to discrete impairment charges taken when, in the 
Company’s estimation, the fair value of a right-of-use asset is below the carrying value. Variable lease cost are the 
amounts owed by the Company to a lessor that are not fixed, such as reimbursement for common area maintenance 
and utilities costs, and are not included in the calculation of the Company’s operating lease right of use assets or 
operating lease liabilities and are expensed when incurred. Sublease income represents the straight-line recognition 
of base rent sublease income over the term of the Sublease, and recognition of pass-through operating expense costs 
per the terms of the Sublease.

11. Notes Payable 

In May 2019, as amended in April 2020, the Company entered into a senior term facilities agreement (the “Credit 
Facility”) with MidCap Financial (Ireland) Limited (“MidCap Financial”), as agent, and additional lenders from 
time to time (together with MidCap Financial, the “Lenders”), to borrow up to $75.0 million in term loans. To date, 
the Company has borrowed $25.0 million under an initial term loan. The remaining $50.0 million under the Credit 
Facility may be drawn down in the form of a second and third term loan, the second term loan being a $25.0 million 
term loan available no earlier than July 1, 2020 and no later than March 31, 2021 upon submission of certain 
regulatory filings and evidence of the Company having $100.0 million in cash and cash equivalent investments; and 
the third term loan being a $25.0 million term loan available no earlier than July 1, 2020 and no later than 
September 30, 2021 upon certain regulatory approvals and evidence of the Company having $125.0 million in cash 
and cash equivalent investments. As of December 31, 2020, the Company had met the criteria to draw down the 
second and third term loans totaling $50.0 million. 

The term loans under the Credit Facility will terminate on the fifth anniversary of the Closing Date (the “Loan 
Maturity Date”). Each term loan under the Credit Facility bears interest at an annual rate equal to 6% plus LIBOR. 
The Company is required to make interest-only payments on the term loan for all payment dates prior to 24 months 
following the date of the Credit Facility, unless the third tranche is drawn, in which case the Company is required to 
make interest-only payments for all payment dates prior to 36 months following the date of the Credit Facility. The 
term loans under the Credit Facility will begin amortizing on either the 24-month or the 36-month anniversary of the 
Credit Facility (as applicable), with equal monthly payments of principal plus interest to be made by the Company to 
the Lenders in consecutive monthly installments until the Loan Maturity Date. In addition, a final payment of 4.5% 
is due on the Loan Maturity Date. The Company accrues the final payment amount of $1.1 million associated with 
the first term loan, to outstanding debt by charges to interest expense using the effective-interest method from the 
date of issuance through the maturity date. 

The Credit Facility includes affirmative and negative covenants. The affirmative covenants include, among others, 
covenants requiring the Company to maintain their legal existence and governmental approvals, deliver certain 
financial reports, maintain insurance coverage, maintain property, pay taxes, satisfy certain requirements regarding 
accounts and comply with laws and regulations. The negative covenants include, among others, restrictions on the 
Company transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying

under the 2018 Plan or 2016 Plan. The board of directors has determined not to make any further awards under the 
2016 plan. As of December 31, 2020, 6,611,693 shares remained available for grant under the 2018 Plan, 1,000,000 
remained available under the Inducement Plan, and 1,470,104 shares remained available for grant under the ESPP. 

Prior to the Company’s IPO, the Company granted options to United States employees and non-employees at 
exercise prices deemed by the board of directors to be equal to the fair value of the ordinary share at the time of 
grant, and granted options to United Kingdom and European Union employees and non-employees at an exercise 
price equal to the par value of the ordinary shares of £0.00001. After the IPO, options are now granted at exercise 
prices equal to the fair value of the Company’s ordinary shares on the grant date for all employees. The vesting 
period is determined by the board of directors, which is generally four years. An option’s maximum term is 
ten years.  

Share options 

The fair value of each stock option award is determined on the date of grant using the Black-Scholes option-pricing 
model. The risk-free interest rate is based on a U.S. treasury instrument whose term is consistent with the expected 
term of the stock options. The expected term of the Company’s options has been determined utilizing the 
“simplified” method for awards that qualify as “plain-vanilla” options. The expected volatility is based on the 
historical volatility of a representative group of companies with similar characteristics to the Company, including 
those in the early stages of product development with a similar and therapeutic focus. For these analyses, the 
Company selects companies with comparable characteristics to its own including enterprise value, risk profiles, 
position within the industry, and with historical share price information sufficient to meet the expected term of the 
options. The relevant data used to determine the value of stock option awards are as follows:

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the options and 
the fair value of the Company’s ordinary shares for those options that had exercise prices lower than the fair value of 
the Company’s ordinary shares. During the years ended December 31, 2020 and 2019, the total intrinsic value of 
share options exercised was $5.0 million and $17.2 million, respectively. During the years ended December 31, 
2020 and 2019, the total proceeds to the Company from share options exercised was $3.9 million and $2.0 million, 
respectively. As of December 31, 2020, and 2019, there was $0.2 million and nil in employee equity plan proceeds 
received after year-end, respectively. 

The weighted average grant date fair value of the options granted during the years ended December 31, 2020 and 
2019 was $7.22 per shares and $8.67 per share, respectively. 

Restricted Share Units 

Performance-based share units 

The Company has issued performance-based restricted share units (“RSUs”) to certain executives and members of 
its senior management, with vesting linked to the achievement of three specific regulatory and research and 
development milestones and one market condition based upon the volume weighted-average price (“VWAP”) of the 
Company’s ADSs for a certain period. Upon achievement of any of the aforementioned milestones, one third of the 
RSUs will vest, and the award will become fully vested upon achievement of three of the four performance 
conditions.  No performance-based share units vested during the years ended December 31, 2020 or 2019. 

The fair value associated with the performance-based conditions is recognized when achievement of the milestones 
becomes probable, if at all. In the fourth quarter of 2020, the Company determined that a performance milestone was 
probable upon approval of Libmeldy by the European Commission in December 2020, and recognized $1.2 million 
in compensation cost. The shares associated with recognition of this performance milestone vested and were issued 
in January 2021. The amount of compensation cost recognized for the years ended December 31, 2020 and 2019 for 
the market condition associated with the performance-based RSUs was $0.3 million and $1.2 million, respectively. 

CEO Award 

The Company granted 195,000 performance-based RSUs with a total grant date fair value of $1.4 million to its 
Chief Executive Officer, Bobby Gaspar, M.D., Ph.D., in April 2020.  The award vests on January 2, 2024 as to 1/3 
of the award for each of the first three to occur of four milestones, if each such milestone is achieved by the 
Company on or before December 31, 2023 and Dr. Gaspar remains continuously employed with the Company 
through January 2, 2024. The milestones relate to achievement of specific clinical and regulatory milestones. No 
performance-based share unit performance conditions associated with the CEO award were deemed probable and 
none vested during the year ended December 31, 2020.

The Company had 6,775,336 unvested options outstanding as of December 31, 2020. As of December 31, 2020, 
total unrecognized compensation cost related to unvested stock option grants and time-based RSUs was 
approximately $46.4 million. This amount is expected to be recognized over a weighted average period of 
approximately 2.52 years. As of December 31, 2020, the total unrecognized compensation cost related to 
performance-based RSUs is a maximum of $4.0 million, dependent upon achievement of milestones.  

14. License and Research Arrangements  

GSK asset purchase and license agreement  

In April 2018, the Company completed an asset purchase and license agreement (the “GSK Agreement”) with 
subsidiaries of GSK to acquire a portfolio of autologous ex vivo gene therapy assets and licenses, for rare diseases 
and option rights on three additional programs in preclinical development from Telethon Foundation and San 
Raffaele Hospital (“Telethon-OSR”). The portfolio of programs and options acquired consisted of:  

• 

• 

• 

• 

Two late-stage clinical gene therapy programs in ongoing registrational trials for MLD and WAS;  

One earlier stage clinical gene therapy program for TDT;  

Strimvelis, the first autologous ex vivo gene therapy for ADA-SCID which was approved for 
marketing by the European Medicines Agency in 2016; and  

Option rights exercisable upon completion of clinical proof of concept studies for three additional 
earlier-stage development programs, which option rights have all subsequently lapsed.  

The Company accounted for the GSK Agreement as an asset acquisition, since the asset purchase and licensing 
arrangement did not meet the definition of a business pursuant to ASC 805, Business Combinations. Total 
consideration was £94.2 million ($133.6 million at the acquisition date), which included an upfront payment of 
£10.0 million ($14.2 million at the acquisition date) and 12,455,252 convertible preferred shares of the Company 
issued to GSK at an aggregate value of £65.8 million ($93.4 million at the acquisition date), a loss contract on the

Strimvelis program valued at £12.9 million ($18.4 million), an inventory purchase liability valued at £4.9 million 
($6.9 million) and transaction costs of £0.6 million ($0.8 million). The Company allocated £94.2 million 
($133.6 million) to in-process research and development expense (based on the fair value of the underlying 
programs in development). The convertible preferred shares were converted to ordinary shares as part of our IPO in 
November 2018. 

The Company is required to use commercially reasonable efforts to obtain a Priority Review Voucher (“PRV”) from 
the United States Food and Drug Administration for each of the programs for MLD, WAS and TDT, the first of 
which GSK retained beneficial ownership over. GSK also has an option to acquire, at a price pursuant to an agreed 
upon formula, any PRV granted to the Company thereafter for MLD, WAS and TDT. If GSK does not exercise this 
option to purchase any PRV, the Company may sell the PRV to a third party and must share any proceeds in excess 
of a specified sale price equally with GSK. For accounting purposes, as of December 31, 2020, the Company does 
not consider the attainment of a PRV from the United States Food and Drug Administration to be probable. 

As part of the GSK Agreement the Company is required to use its best endeavors to make Strimvelis commercially 
available in the European Union until such time as an alternative gene therapy, such as the Company’s OTL-101 
product candidate, is commercially available for patients in Italy, and at all times at the San Raffaele Hospital in 
Milan, provided that a minimum number of patients continue to be treated at this site. Strimvelis is not currently 
expected to generate sufficient cash flows to overcome the costs of maintaining the product and certain regulatory 
commitments; therefore, the Company recorded a liability associated with the loss contract of £12.9 million ($18.4 
million at the acquisition date) associated with the loss expected due to this obligation. This liability is being 
amortized over the remaining period of expected sales of Strimvelis as a credit to research and development 
expenses (see Note 2). 

The Company will pay GSK non-refundable royalties and milestone payments in relation to the gene therapy 
programs acquired and OTL-101. The Company will pay a flat mid-single digit percentage royalty on the combined 
annual net sales of ADA-SCID products, which includes Strimvelis and the Company-developed product candidate, 
OTL-101. The Company will also pay tiered royalty rates at a percentage beginning in the mid-teens up to twenty 
percent for the MLD and WAS products, upon marketing approval, calculated as percentages of aggregate 
cumulative net sales of the MLD and WAS products, respectively. The Company will pay a tiered royalty at a 
percentage from the high single-digits to low double-digit for the TDT product, upon marketing approval, calculated 
as percentages of aggregate annual net sales of the TDT product. These royalties owed to GSK are in addition to any 
royalties owed to other third parties under various license agreements for the GSK programs. In aggregate, the 
Company may pay up to £90.0 million in milestone payments upon achievement of certain sales milestones 
applicable to GSK. The Company’s royalty obligations with respect to MLD and WAS may be deferred for a certain 
period in the interest of prioritizing available capital to develop each product. The Company’s royalty obligations 
are subject to reduction on a product-by-product basis in the event of market control by biosimilars and will expire 
in April 2048. Other than Strimvelis, these royalty and milestone payments were not determined to be probable and 
estimable at the date of the acquisition and are not included as part of consideration.  

The Company and GSK also separately executed a Transition Services Agreement (“TSA”) as well as an Inventory 
Sale Agreement, in April 2018. The TSA outlined several activities that the Company had requested GSK to assist 
with during the transition period, including but not limited to utilizing GSK to sell, market and distribute Strimvelis, 
and assist with regulatory, clinical and non-clinical activities for the other non-commercialized products which were 
ongoing at the date of the GSK Agreement. The TSA expired in December 2018.  

In connection with the Company’s entering into the GSK Agreement, GSK assigned rights and obligations to certain 
contracts, which include among others, the original license agreement with Telethon-OSR and an ongoing 
manufacturing agreement (see Note 16).  

Telethon-OSR research and development collaboration and license agreements 

In connection with the Company’s entering into the GSK Agreement, the Company also acquired and assumed 
agreements with Telethon Foundation and San Raffaele Hospital, together referred to as Telethon-OSR, for the 
research, development and commercialization of autologous ex vivo gene therapies for ADA-SCID, WAS, MLD, 
TDT, as well as options over three additional earlier-stage development programs. The Company’s options under the 
agreement with Telethon-OSR with respect to the earlier-stage programs have lapsed. 

F-26 

Orchard Therapeutics plc  157

 
 
 
As consideration for the licenses, the Company will be required to make payments to Telethon-OSR upon 
achievement of certain product development milestones. Additionally, the Company will be required to pay to 
Telethon-OSR a tiered mid-single to low-double digit royalty percentage on annual sales of licensed products 
covered by patent rights on a country-by-country basis, as well as a low double-digit percentage of sublicense 
income received from any certain third-party sublicenses of the collaboration programs. These royalties are in 
addition to those payable to GSK under the GSK Agreement. The Company may pay up to an aggregate of 
approximately €31.0 million ($38.1 million at December 31, 2020) in milestone payments upon achievement of 
certain product development milestones for the program. 

In May 2019, the Company entered into a license agreement with Telethon-OSR, under which Telethon-OSR 
granted to the Company an exclusive worldwide license for the research, development, manufacture and 
commercialization of Telethon-OSR’s ex vivo autologous HSC lentiviral based gene therapy for the treatment of 
mucopolysaccharidosis type I (“MPS-I”), including the Hurler variant. To date, Telethon-OSR received €17.0 
million in upfront and milestone payments from the Company upon entering into the agreement and shortly 
thereafter, resulting in $19.4 million in in-process research and development expense. The Company is also required 
to make milestone payments contingent upon certain development, regulatory and commercial milestones are 
achieved and may pay up to  €28.0 million ($34.4 million at December 31, 2020). Additionally, the Company will 
be required to pay Telethon a tiered mid-single to low-double digit royalty percentage on annual net sales of 
licensed products.  

UCLB/UCLA License Agreement  

In February 2016, and amended in July 2017, the Company completed the UCLB/UCLA license agreement, under 
which the Company has been granted exclusive and non-exclusive, sublicensable licenses under certain intellectual 
property rights controlled by UCLB and UCLA to develop and commercialize gene therapy products in certain 
fields and territories.  

In exchange for these rights, in 2016, the Company made upfront cash payments consisting of $0.8 million for the 
license to the joint UCLB/UCLA technology and $1.1 million for the license to the UCLB technology and 
manufacturing technology. The Company also issued an aggregate of 4,665,384 ordinary shares to UCLB, of which 
1,224,094, and 3,441,290 ordinary shares were issued in 2017 and 2016, respectively. The Company recorded 
research and development expense based on the fair value of the ordinary shares as of the time the agreement was 
executed or modified. The Company was also obligated to make an additional cash payment for clinical data. In 
2017, the Company paid $0.8 million in relation to clinical data acquired. The Company recorded the payments to 
research and development expense.  

Under the UCLB/UCLA License Agreement, the Company is also obligated to pay an annual administration fee of 
$0.1 million on the first, second and third anniversary of the agreement date. Additionally, the Company may 
become obligated to make payments to the parties of up to an aggregate of £19.9 million upon the achievement of 
specified regulatory milestones as well as royalties ranging from low to mid-single-digit percentage on net sales of 
the applicable gene therapy product.  

The Company recorded $0.1 million of research and development costs in respect of the UCLB/UCLA license 
agreement, which comprise the upfront payments, issuance of ordinary shares and payments for clinical data, for 
each of the years ended December 31, 2020 and 2019. 

Unless terminated earlier by either party, the UCLB/UCLA license agreement will expire on the 25th anniversary of 
the agreement.

Oxford BioMedica license, development and supply agreement  

In November 2016, and as amended in June 2017, May 2018, July 2018, September 2018, May 2019 and April 
2020, the Company entered into an arrangement with Oxford BioMedica whereby Oxford BioMedica granted an 
exclusive intellectual property license to the Company for the purposes of research, development, and 
commercialization of collaboration products, and will provide process development services, and manufacture 
clinical and commercial GMP-grade lentiviral vectors to the Company (“Oxford BioMedica Agreement”). As part of 
the consideration to rights and licenses granted under the Oxford BioMedica Agreement, the Company issued 
588,220 ordinary shares to Oxford BioMedica. The Company is also obligated to make certain development 
milestone payments in the form of issuance of additional ordinary shares if the milestones are achieved. In 
November 2017, the first milestone was achieved, and the Company was committed to issue another 150,826 
ordinary shares, and issued these shares in 2018. In September 2018, the second and fourth milestones were 
achieved, and the Company issued 150,826 ordinary shares. In April 2020, the fifth milestone was deemed to have 
been met upon execution of the amended agreement in April 2020, and the Company issued 75,413 ordinary shares 
to Oxford BioMedica with a total value of $0.8 million, which was expensed to research and development expense. 
No milestones were met during the year ended December 31, 2019. 

The Company may also pay low single-digit percentage royalties on annual net sales of collaborated product 
generated under the Oxford BioMedica Agreement.

The Company’s income tax benefit for the year ended December 31, 2020 compared to the year ended December 
31, 2019 decreased primarily related to shortfall of tax deduction from share-based compensation and reduction of 
U.S. deduction for foreign derived intangible income (“FDII”) and U.S. federal research and development tax 
credits.   

The Company accounts for income taxes in accordance with ASC Topic 740. Deferred income tax assets and 
liabilities are determined based upon temporary differences between the financial reporting and tax bases of assets 
and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are 
expected to reverse. The following table presents the principal components of the Company’s deferred tax assets and 
liabilities as of December 31, 2020 and 2019:

For the years ended December 31, 2020 and 2019, the Company had cumulative UK net operating loss 
carryforwards of approximately $390.1 million and $266.8 million, respectively. Unsurrendered UK losses may be 
carried forward indefinitely, subject to numerous utilization criteria and restrictions and are fully offset by a 
valuation allowance. 

For the year ended December 31, 2020, the Company had cumulative U.S. federal general business and U.S. state 
research and development tax credit carryforwards of approximately $2.0 million available to reduce future U.S. 
state tax liabilities. The U.S. state tax credit carryforwards can be carried forward indefinitely and are fully offset by 
a valuation allowance.

In measuring the Company’s deferred tax assets, the Company considers all available evidence, both positive and 
negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed for all or 
some portion of the deferred tax assets. Significant judgment is required in considering the relative impact of the 
negative and positive evidence, and weight given to each category of evidence is commensurate with the extent to 
which it can be objectively verified. The more negative evidence that exists, the more positive evidence is necessary, 
and the more difficult it is to support a conclusion that a valuation allowance is not needed. Additionally, the 
Company utilizes the "more likely than not" criteria established in FASB ASC Topic 740 to determine whether the 
future tax benefit from the deferred tax assets should be recognized. As a result, the Company has established 
valuation allowances on the deferred tax assets in jurisdictions that have incurred net operating losses and in which 
it is more likely than not that such losses will not be utilized in the foreseeable future. 

As of each reporting date, we consider new evidence, both positive and negative, that could impact our view with 
regard to future realization of our deferred tax assets. Management has considered the Company’s history of 
cumulative net losses in the UK, along with estimated future taxable income and has concluded that it is more likely 
than not that the Company will not realize the benefits of its UK deferred tax assets and U.S. state research and 
development tax credits. Accordingly, the Company has maintained a full valuation allowance against these net 
deferred tax assets as of December 31, 2020 and 2019, respectively.   

Changes in the valuation allowance for deferred tax assets during the years ended December 31, 2020 and 2019 
related primarily to the increase in UK net operating loss carryforwards and UK amortization of intangible assets 
and were as follows: 

Valuation allowance as of beginning of year 

Decreases recorded as benefit to income tax provision 
Increases recorded to income tax provision 
Effect of foreign currency translation 

Valuation allowance as of end of year

The Company applies the authoritative guidance on accounting for and disclosure of uncertainty in tax positions, 
which requires the Company to determine whether a tax position of the Company is more likely than not to be 
sustained upon examination, including resolution of any related appeals of litigation processes, based on the 
technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount 
recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood 
of being realized upon the ultimate settlement with the relevant taxing authority. There were no material uncertain 
tax positions as of December 31, 2020 and 2019.  

The Company will recognize interest and penalties related to uncertain tax positions in income tax expense when in 
a taxable income position. As of December 31, 2020, and 2019, the Company had no accrued interest or penalties 
related to uncertain tax positions and no amounts have been recognized in the Company’s statement of operations. 

The Company and its subsidiaries file income tax returns in the UK, the U.S., and various foreign jurisdictions. 
Generally, the tax years 2017 through 2020 remain open to examination by the major taxing jurisdictions to which 
the Company is subject. To the extent the Company has tax attribute carryforwards, the tax years in which the 
attribute was generated may still be adjusted upon examination by the federal, state, or foreign tax authorities, if 
such tax attributes are utilized in a future period.
