GENERAL INFORMATION

Unless  otherwise  indicated  or  the  context  otherwise  requires,  all  references  in  this  Annual  Report  to  the  terms  “ASLAN,”  “ASLAN 
Pharmaceuticals,” “the company,” “we,” “us” and “our” refer to ASLAN Pharmaceuticals Limited and its subsidiaries. 

PRESENTATION OF FINANCIAL AND OTHER INFORMATION

Our consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS), as issued 
by the International Accounting Standard Board (IASB), which may differ in material respects from generally accepted accounting principles 
in other jurisdictions, including the United States. 

Our functional currency is the U.S. dollar. Unless otherwise specified, all monetary amounts presented are in U.S. dollars. All references in 
this Annual Report to “$” mean U.S. dollars, all references in this Annual Report to “NT$” mean New Taiwan dollars, the legal currency of 
the Republic of China (ROC), and all references in this Annual Report to “SG$” mean Singapore dollars, the legal currency of Singapore. No 
representation is made that the New Taiwan dollar amounts referred to herein could have been or could be converted into U.S. dollars at any 
particular rate or at all. Any discrepancies in any table between totals and sums of the amounts listed are due to rounding. 

We have made rounding adjustments to some of the figures included in this Annual Report. Accordingly, numerical figures shown as totals in 
some tables may not be an arithmetic aggregation of the figures that preceded them.

On  March  13,  2023,  we  effected  a  change  to  the  ratio  of  our  American  Depositary  Shares  (ADSs)  to  our  ordinary  shares  from  one  ADS 
representing  five  ordinary  shares  to  one  ADS  representing  twenty-five  ordinary  shares  (the  ADS  Ratio  Change).  Except  as  otherwise 
indicated, all information in this Annual Report does not give retroactive effect to the ADS Ratio Change.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and 
Section 21E of the Securities Exchange Act of 1934, as amended (Exchange Act), that involve substantial risks and uncertainties. In some 
cases,  you  can  identify  forward-looking  statements  by  the  words  “may,”  “might,”  “will,”  “could,”  “would,”  “should,”  “expect,”  “intend,” 
“plan,” “objective,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue” and “ongoing,” or the negative of these terms, or 
other  comparable  terminology  intended  to  identify  statements  about  the  future.  These  statements  involve  known  and  unknown  risks, 
uncertainties and other important factors that may cause our actual results, levels of activity, performance or achievements to be materially 
different  from  the  information  expressed  or  implied  by  these  forward-looking  statements.  The  forward-looking  statements  and  opinions 
contained in this Annual Report on Form 20-F are based upon information available to us as of the date of this Annual Report and, while we
believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements 
should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.

company (PFIC) for U.S. federal income tax purposes; 

Our estimates regarding expenses, future revenue, capital requirements and needs for additional financing; and 

Our expectations regarding the terms of our patents and ability to obtain and maintain intellectual property protection for our 
product candidates. 

You should refer to the section titled “Item 3.D. – Risk Factors” for a discussion of important factors that may cause our actual results to 
differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that 
the forward-looking statements in this Annual Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be 
inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard 
these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time 
frame, or at all. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future 
events or otherwise, except as required by law. We claim the protection of the safe harbor for forward-looking statements contained in the 
Private Securities Litigation Reform Act of 1995 for all forward-looking statements.

You should read this Annual Report and the documents that we reference in this Annual Report, completely and with the understanding that 
our  actual  future  results  may  be  materially  different  from  what  we  expect.  We  qualify  all  of  our  forward-looking  statements  by  these 
cautionary statements. 

Unless otherwise indicated, information contained in this Annual Report on Form 20-F concerning our industry and the markets in which we 
operate, including our general expectations and market position, market opportunity and market size estimates, is based on information from 
independent  industry  analysts,  third-party  sources  and  management  estimates.  Management  estimates  are  derived  from  publicly  available 
information released by independent industry analysts and third-party sources, as well as data from our internal research, and are based on 
assumptions made by us based on such data and our knowledge of such industry and market, which we believe to be reasonable. In addition, 
while  we  believe  the  market  opportunity  information  included  in  this  Annual  Report  on  Form  20-F  is  generally  reliable  and  is  based  on 
reasonable  assumptions,  such  data  involve  risks  and  uncertainties  and  are  subject  to  change  based  on  various  factors,  including  those 
discussed under the section of this Annual Report on Form 20-F titled “Item 3.D. – Risk Factors.”

SUMMARY OF RISK FACTORS

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

• We have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the 

foreseeable future.

• We currently do not generate any revenue from product sales, have generated only limited revenue since inception, and may 

never be profitable.

• We will need to obtain substantial additional financing for our operations, and if we fail to obtain additional financing, we may 

be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

• We  are  heavily  dependent  on  the  success  of  our  two  product  candidates,  eblasakimab  (also  known  as  ASLAN004)  and 

farudodstat (also known as ASLAN003) and we cannot give any assurance that 

4

•

•

•

eblasakimab or farudodstat will successfully complete clinical development or receive regulatory approval, which is necessary 
before they can be commercialized.

Clinical  development  is  a  lengthy  and  expensive  process  with  an  uncertain  outcome,  and  results  of  earlier  studies  and  trials 
may not be predictive of future trial results. Failure can occur at any stage of clinical development. We have never completed a 
pivotal  clinical  trial  for  our  product  candidates  or  submitted  a  New  Drug  Application  (NDA)  or  a  Biologics  License 
Application  (BLA)  to  the  U.S.  Food  and  Drug  Administration  (U.S.  FDA)  or  similar  drug  approval  filings  to  comparable 
foreign authorities. 

Delays in clinical trials are common and have many causes, and any delay could result in increased costs to us and jeopardize
or delay our ability to obtain regulatory approval and commence product sales. 

The  regulatory  approval  processes  of  the  U.S.  FDA  and  comparable  foreign  authorities  are  lengthy,  time  consuming  and 
inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business 
will be substantially harmed. 

• We rely on third parties to conduct our preclinical studies and clinical trials. If these third parties do not successfully carry out 
their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our 
product candidates and our business could be substantially harmed.

•

•

•

If we are unable to obtain or protect intellectual property rights related to our current product candidates or any future product 
candidates which we may develop, we may not be able to compete effectively in our market. 

If  we  are  unable  to  regain  compliance  with  the  listing  requirements  of  the  Nasdaq  Capital  Market,  our  ADSs  may  remain 
delisted from the Nasdaq Capital Market which could have a material adverse effect on our financial condition and could make 
it more difficult for you to sell your shares.

You  may  face  difficulties  in  protecting  your  interests,  and  your  ability  to  protect  your  rights  through  U.S.  courts  may  be 
limited, because we are incorporated under Cayman Islands law, we conduct the majority of our operations, and substantially 
all of our directors and executive officers reside, outside of the United States. 

• We qualify as a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act 

reporting obligations that permit less detailed and frequent disclosures than those of a U.S. domestic public company.

•

•

Our business is subject to economic, political, regulatory and other risks associated with international operations.

Our business could continue to be adversely affected by the effects of health pandemics or epidemics, including the effects of 
the COVID-19 pandemic.

Risk Factors.

An investment in our American Depositary Shares (ADSs) involves a high degree of risk. The occurrence of any of the events or developments 
described  below  could  harm  our  business,  financial  condition,  results  of  operations  and/or  prospects  or  cause  our  actual  results  to  differ 
materially from those contained in forward-looking statements we have made in this report and those we may make from time to time. In such 
an event, the market price of our ADSs or ordinary shares could decline and you may lose all or part of your investment. You should consider
all of the risk factors described when evaluating our business. 

Risks Related to Our Financial Condition and Need for Additional Capital 

We have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable 
future. 

We are a clinical-stage immunology focused biopharmaceutical company developing innovative treatments to transform the lives of patients. 
Investment  in  biopharmaceutical  product  development  is  highly  speculative  because  it  entails  substantial  upfront  capital  expenditures  and 
significant risk that any potential product candidate will not demonstrate adequate effectiveness in the targeted indication or an acceptable 
safety  profile,  gain  regulatory  approval  or  become  commercially  viable.  All  of  our  product  candidates  will  require  substantial  additional 
development time and resources before we would be able to apply for or receive regulatory approvals and begin generating revenue from 
product sales. We are not profitable and have incurred net losses in each year since our inception, including net losses of $17.0 million, $31.6 
million and $51.4 million for fiscal years 2020, 2021 and 2022, respectively. As of December 31, 2021 and 2022, we had an accumulated 
deficit of $227.0 million and $278.4 million, respectively.  

6

We  have  devoted  substantially  all  our  financial  resources  to  developing  our  product  candidates  and  targeted  discovery  work,  including 
preclinical development activities and clinical trials. We expect to continue to incur substantial expenses, losses and negative cash flows as 
we expand our development activities and advance our clinical programs, particularly with respect to our planned clinical development for 
eblasakimab  (also  known  as  ASLAN004)  and  farudodstat  (also  known  as  ASLAN003).  If  our  product  candidates  are  not  successfully 
developed or commercialized, including because of a lack of capital, or if we do not generate enough revenue following marketing approval, 
we will not achieve profitability and our business may fail. 

We  currently  do  not  generate  any  revenue  from  product  sales,  have  generated  only  limited  revenue  since  inception,  and  may  never  be 
profitable. 

We do not anticipate generating revenue from sales of our proprietary product candidates for the foreseeable future. Our ability to generate 
future  revenue  from  product  sales  depends  on  our  success  in  completing  clinical  development  of,  obtaining  regulatory  approval  for,  and 
launching and successfully commercializing any product candidates. 

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to predict the timing or 
amount of increased expenses, when, or if, we will begin to generate revenue from product sales, or when, or if, we will be able to achieve or 
maintain profitability. In addition, our expenses could increase beyond planned levels if we are required by the U.S. FDA to perform studies 
in addition to those that we currently anticipate or if such studies are larger, take longer or are otherwise more expensive to conduct than we 
expect. 

Even if one or more of our product candidates is approved for commercial sale, to the extent we do not engage a third-party collaborator, we 
anticipate  incurring  significant  costs  associated  with  commercializing  any  approved  product  candidate.  Even  if  we  are  able  to  generate 
revenue  from  the  sale  of  any  approved  products,  we  may  not  become  profitable  and  may  need  to  obtain  additional  funding  to  continue 
operations. 

We will need to obtain substantial additional financing for our operations, and if we fail to obtain additional financing, we may be forced 
to delay, reduce or eliminate our product development programs or commercialization efforts. 

Developing  pharmaceutical  products,  including  conducting  preclinical  studies  and  clinical  trials,  is  expensive  and  we  have  consumed 
substantial  amounts  of  capital  since  inception.  To  date,  we  have  financed  our  operations  through  government  subsidies  and  grants, 
collaboration payments and the sale of equity securities, venture debt and convertible debt. We will need substantial additional financing to 
continue  our  operations  and  do  not  expect  revenues  from  product  sales  or  potential  licensing  transactions  to  be  sufficient  to  offset  our 
development expenses as we advance our clinical programs. 

We  had  approximately  $56.9  million  of  cash  and  cash  equivalents  as  of  December  31,  2022.  As  we  are  in  the  clinical  research  and 
development phase, we will be seeking future funding based on the requirements of our business operations. We intend to continue to explore 
various means of fundraising to meet our funding requirements to carry out our business operations, such as offerings of ADSs, follow-on 
offerings of ordinary shares, venture debt and shareholder loans. We may also use other means of financing such as out-licensing to generate 
revenue and cash. We have the ability to exercise discretion and flexibility to deploy our capital resources used in research and development 
activities according to the amount and timing of our financing activities. Accordingly, we believe that our existing cash and cash equivalents, 
including the proceeds from our recent private placement offering in February 2023, will enable us to fund our operating expenses and capital 
expenditure  requirements  and  meet  our  obligations  for  at  least  the  next  twelve  months  from  December  31,  2022.  However,  our  future 
viability  depends  on  our  ability  to  raise  additional  capital  to  finance  our  operations.  Regardless  of  our  expectations  as  to  how  long  our 
existing cash and cash equivalents will fund our operations, changing circumstances beyond our control may cause us to consume capital 
more rapidly than we currently anticipate. For example, our clinical trials may encounter technical, enrollment or other difficulties that could 
increase  our  development  costs  more  than  we  expect.  We  may  also  incur  expenses  as  we  create  additional  infrastructure  to  support  our 
planned  commercialization  efforts  and  our  operations  as  a  U.S.  public  company.  In  any  event,  we  will  require  additional  capital  prior  to 
completing pivotal studies of, filing for regulatory approval for, or commercializing farudodstat and eblasakimab. 

7

 
 
 
 
 
 
 
We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. If we are unable to 
raise additional capital when required or on acceptable terms, we may be required to:

•

•

•

Significantly delay, scale back or discontinue the development or commercialization of our product candidates; 

Seek corporate partners for our product candidates when we would otherwise develop our product candidates on our own, or at 
an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available; 

Relinquish or license on unfavorable terms, our rights to technologies or product candidates that we otherwise would seek to 
develop or commercialize ourselves; or 

Significantly curtail or cease operations. 

If  we  are  unable  to  raise  additional  capital  in  sufficient  amounts  or  on  terms  acceptable  to  us,  we  will  be  prevented  from  pursuing 
development and commercialization efforts, which will have an adverse effect on our business, operating results and prospects. 

Risks Related to Clinical Development and Regulatory Approval 

We are heavily dependent on the success of our two product candidates, eblasakimab and farudodstat and we cannot give any assurance 
that eblasakimab or farudodstat will successfully complete clinical development or receive regulatory approval, which is necessary before 
they can be commercialized. 

Our  business  and  future  success  is  substantially  dependent  on  our  ability  to  successfully  develop,  obtain  regulatory  approval  for,  and 
successfully  commercialize  eblasakimab  and  farudodstat.  Any  delay  or  setback  in  the  development  of  eblasakimab  or  farudodstat  could 
materially  and  adversely  affect  our  business  and  operations  and  cause  the  price  of  our  ADSs  or  ordinary  shares  to  decline.  Should  our 
planned clinical development of eblasakimab and farudodstat fail to be completed in a timely manner or at all, we will need to acquire new 
preclinical  product  candidates,  which  will  require  additional  time  and  resources  to  obtain  regulatory  approval  and  proceed  with 
commercialization.  We  cannot  assure  you  that  our  planned  clinical  development  for our  product  candidates  will  be  completed  in  a  timely 
manner in our current indications, or at all, or that we will be able to obtain approval for any of our product candidates from the U.S. FDA, or 
any comparable foreign regulatory authority. 

Clinical development is a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be 
predictive of future trial results. Failure can occur at any stage of clinical development. We have never completed a large scale pivotal 
clinical trial for any product candidates or submitted an NDA or a BLA to the U.S. FDA or similar drug approval filings to comparable 
foreign authorities. 

Clinical testing is expensive and takes many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during 
the  clinical  trial  process.  The  results  of  preclinical  studies  and  early  clinical  trials  of  our  product  candidates  may  not  be  predictive  of  the 
results of subsequent clinical trials. We have a limited operating history and to date have not demonstrated our ability to complete large scale 
pivotal clinical trials. 

Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through 
preclinical studies and initial clinical trials. In addition to the safety and efficacy traits of any product candidate, clinical trial failures may 
result from a multitude of factors, including flaws in trial design, dose selection, placebo effect and patient enrollment criteria. A number of 
companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse 
safety  profiles,  notwithstanding  promising  results  in  earlier  trials.  Based  upon  negative  or  inconclusive  results,  we  or  any  potential  future 
collaborator may decide, or regulators may require us, to conduct additional clinical trials or preclinical studies. In addition, data obtained 
from trials and studies are susceptible to varying interpretations, and regulators may not interpret our data as favorably as we do, which may 
delay, limit or prevent regulatory approval. Our future clinical trials may not be successful. 

8

 
 
 
 
 
 
 
If any product candidate is found to be unsafe or lack efficacy, we will not be able to obtain regulatory approval for it and our business may 
be materially harmed. For example, if the results of our ongoing Phase 2b clinical trial of eblasakimab in atopic dermatitis, our planned Phase 
2 clinical trial of farudodstat in alopecia areata (AA) or any other clinical trials for our product candidates, demonstrate unexpected safety 
findings or do not achieve the primary efficacy endpoints, the prospects for approval of these product candidates, as well the price of our 
ADSs and ordinary shares and our ability to create shareholder value would be materially and adversely affected. 

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate 
due to numerous factors, including changes in trial protocols, differences in composition of the patient populations, adherence to the dosing 
regimen and other trial protocols and the dropout rate among clinical trial participants. For example, we could be required to use a primary 
endpoint in our pivotal trials that is different from endpoints in our Phase 2 clinical trials, which could result in negative or less compelling 
efficacy results in pivotal trials despite promising results in Phase 2 clinical trials. We do not know whether any future clinical trials we may 
conduct will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates. If we are 
unable to complete clinical development for any of our current or future product candidates, our ability to create long-term shareholder value 
will be limited. 

Interim, top-line and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient 
data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary or top-line data from our preclinical studies and clinical trials, which is based on a 
preliminary  analysis  of  then-available  data,  and  the  results  and  related  findings  and  conclusions  are  subject  to  change  following  a  more 
comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions 
as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the 
top-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations 
may qualify such results, once additional data have been received and fully evaluated.

Top-line  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being  materially  different  from  the 
preliminary data we previously published. As a result, top-line data should be viewed with caution until the final data are available.

From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data from clinical trials that we 
may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and 
more patient data become available or as patients from our clinical trials continue other treatments for their disease. Material and adverse 
differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim 
data by us or by our competitors could result in volatility in the price of our ADSs or ordinary shares.

Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,  estimations,  calculations,  conclusions  or 
analyses  or  may  interpret  or  weigh  the  importance  of  data  differently,  which  could  impact  the  value  of  the  particular  program,  the 
approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information 
we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or 
others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-
line, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions 
reached,  our  ability  to  obtain  approval  for,  and  commercialize,  our  product  candidates  may  be  harmed,  which  could  harm  our  business, 
operating results, prospects or financial condition.

Delays in clinical trials are common and have many causes, and any delay could result in increased costs to us and jeopardize or delay 
our ability to obtain regulatory approval and commence product sales. 

We may experience delays in clinical trials of our product candidates. Our planned clinical trials may not begin on time, have an effective 
design, enroll a sufficient number of patients, or be completed on schedule, if at all. Our clinical trials can be delayed for a variety of reasons, 
including: 

•

•

•

•

•

•

•

•

•

•

•

•

Inability to raise funding necessary to initiate or continue a trial; 

Delays in obtaining regulatory approval to commence a trial; 

Delays in reaching agreement with the U.S. FDA or other regulatory authorities on final trial design; 

Imposition  of  a  clinical  hold  for  safety  reasons  or  following  an  inspection  of  our  clinical  trial  operations  or  trial  or 
manufacturing sites by the U.S. FDA or other regulatory authorities; 

Delays in reaching agreement on acceptable terms with prospective contract research organizations (CROs) and clinical trial 
sites; 

Delays in obtaining required institutional review board (IRB) approval at each site; 

Delays in recruiting suitable patients to participate in a trial; 

Delays in having patients complete participation in a trial or return for post-treatment follow-up; 

Clinical sites dropping out of a trial to the detriment of enrollment; 

Time required to add new clinical sites; 

Delays by our contract manufacturers to produce and deliver sufficient supply of clinical trial materials; or

Disruptions caused by man-made or natural disasters or public health pandemics or other business interruptions, including, for 
example, the COVID-19 pandemic or the ongoing conflict between Ukraine and Russia. 

We could also experience delays if physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our 
product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be 
suspended or terminated by us, the IRBs for the institutions in which such trials are being conducted, recommended for termination by any 
data monitoring committee for such trial, or by the U.S. FDA or other regulatory authorities due to a number of factors, including failure to 
conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of clinical trial or manufacturing 
sites by the U.S. FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side 
effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack 
of  adequate  funding  to  continue  the  clinical  trial.  Furthermore,  we  rely  on  CROs  and  clinical  trial  sites  to  ensure  the  proper  and  timely 
conduct of our clinical trials and while we have agreements governing their committed activities, we have limited influence over their actual 
performance. If we experience termination of, or delays in the completion of, any clinical trial of our product candidates, the commercial 
prospects for our product candidates will be harmed, and our ability to generate product revenues will be delayed. In addition, any delays in 
completing our clinical trials will increase our costs and slow down our product development and approval process. Any of these occurrences 
may harm our business, prospects, financial condition and results of operations significantly. 

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial 
of regulatory approval for our product candidates. 

Because  we  have  multiple  product  candidates  in  our  pipeline  and  are  considering  a  variety  of  target  indications,  we  may  expend  our 
limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that 
may be more profitable or for which there is a greater likelihood of success. 

Because  we  have  limited  financial  and  managerial  resources,  we  must  focus  our  research  and  development  efforts  on  those  product 
candidates and specific indications that we believe are the most promising. As a result, we may forego or delay pursuit of opportunities with 
other  product  candidates  or  other  indications  that  later  prove  to  have  greater  commercial  potential.  Our  resource  allocation  decisions  may 
cause us to fail to capitalize on viable commercial products or profitable market opportunities. 

We may in the future spend our resources on other research programs and product candidates for specific indications that ultimately do not 
yield any commercially viable products. Furthermore, if we do not accurately evaluate the 

10

 
 
 
 
 
 
commercial  potential  or  target  addressable  market  for  a  particular  product  candidate,  we  may  relinquish  valuable  rights  to  that  product 
candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to 
retain sole development and commercialization rights. 

Our product candidates may cause adverse events or have other properties that could delay or prevent their regulatory approval or limit 
the scope of any approved label or market acceptance. 

Adverse events (AEs) caused by our product candidates or other potentially harmful characteristics of our product candidates could cause us, 
other reviewing entities, clinical trial sites or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of 
regulatory approval. 
Serious AEs observed in any of our clinical trials may adversely impact our ability to obtain regulatory approval for our product candidates. 
Further, if any of our approved products cause serious or unexpected side effects after receiving market approval, a number of potentially 
significant negative consequences could result, including: 

•

•

Regulatory authorities may withdraw their approval of the product or impose restrictions on its distribution; 

Regulatory authorities may require the addition of labeling statements, such as warnings or contraindications; 

• We may be required to change the way the product is administered or conduct additional clinical studies; 

• We could be sued and held liable for harm caused to patients; or 

•

Our reputation may suffer. 

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  candidate  and  could 
substantially increase the costs of commercializing our product candidates. 

The  regulatory  approval  processes  of  the  U.S.  FDA  and  comparable  foreign  authorities  are  lengthy,  time  consuming  and  inherently 
unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially 
harmed. 

The time required to obtain approval by the U.S. FDA and comparable foreign authorities is unpredictable but typically takes many years 
following  the  commencement  of  clinical  trials  and  depends  upon  numerous  factors,  including  the  substantial  discretion  of  the  regulatory 
authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during 
the course of a product candidate’s clinical development and may vary among jurisdictions. For example, we cannot guarantee that our Phase 
2b clinical trial of eblasakimab in atopic dermatitis will be sufficient to allow subsequent development or that the U.S. FDA or comparable 
foreign regulatory authorities will not require additional or different clinical trials prior to subsequent development of eblasakimab or that the 
required primary endpoints in subsequent pivotal trials or other clinical trials will not be different than those in Phase 2 clinical trials. 

Our product candidates could fail to receive regulatory approval for many reasons, including the following:

•

The  U.S.  FDA  or  comparable  foreign  regulatory  authorities  may  disagree  with  the  design,  scope  or  implementation  of  our 
clinical trials; 

• We  may  be  unable  to  demonstrate  to  the  satisfaction  of  the  U.S.  FDA  or  comparable  foreign  regulatory  authorities  that  a 

product candidate is safe and effective for its proposed indication; 

•

The results of clinical trials may not meet the level of statistical significance required by the U.S. FDA or comparable foreign 
regulatory authorities for approval; 

• We may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks; 

•

•

The  U.S.  FDA  or  comparable  foreign  regulatory  authorities  may  disagree  with  our  interpretation  of  data  from  preclinical 
studies or clinical trials; 

The data collected from clinical trials of our product candidates may not be sufficient to support the submission of an NDA, 
BLA or other submission or to obtain regulatory approval in the United States or elsewhere; 

11

 
 
 
 
 
 
•

•

The  U.S.  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of 
third-party manufacturers with which we contract for clinical and commercial supplies; and 

The approval policies or regulations of the U.S. FDA or comparable foreign regulatory authorities may change significantly in 
a manner rendering our clinical data insufficient for approval. 

This  lengthy  approval  process,  as  well  as  the  unpredictability  of  future  clinical  trial  results,  may  result  in  our  failure  to  obtain  regulatory 
approval to market our product candidates, which would harm our business, results of operations and prospects significantly. 

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited 
indications  than  we  request,  may  not  approve  the  price  we  intend  to  charge  for  our  products,  may  grant  approval  contingent  on  the 
performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims 
necessary  or  desirable  for  the  successful  commercialization  of  that  product  candidate.  Any  of  the  foregoing  scenarios  could  harm  the 
commercial prospects for our product candidates. 

We have not previously submitted an NDA, BLA or any similar drug approval filing to the U.S. FDA or any comparable foreign authority for 
any product candidate, and we cannot be certain that any of our product candidates will be successful in clinical trials or receive regulatory 
approval.  Further,  our  product  candidates  may  not  receive  regulatory  approval  even  if  they  are  successful  in  clinical  trials.  If  we  do  not 
receive  regulatory  approvals  for  our  product  candidates,  we  may  not  be  able  to  continue  our  operations.  Even  if  we  successfully  obtain 
regulatory approvals to market one or more of our product candidates, our revenue will be dependent, to a significant extent, upon the size of 
the markets in the territories for which we gain regulatory approval. If the markets for patients or indications that we are targeting are not as 
significant as we estimate, we may not generate significant revenue from sales of such products, if approved.

Even if we obtain regulatory approval for our product candidates, we will still face extensive regulatory requirements and our products 
may face future development and regulatory difficulties. 

Even if we obtain regulatory approval in the United States or other markets, the U.S. FDA or comparable foreign regulatory authorities, as 
applicable,  may  still  impose  significant  restrictions  on  the  indicated  uses  or  marketing  of  our  product  candidates,  or  impose  ongoing 
requirements  for  potentially  costly  post-approval  studies  or  post-market  surveillance.  Our  product  candidates,  if  approved,  will  also  be 
subject to ongoing U.S. FDA and/or other applicable regulatory requirements governing the labeling, packaging, storage, distribution, safety 
surveillance, advertising, promotion, record-keeping and reporting of safety and other post-market information. The holder of an approved 
NDA  or  BLA  is  obligated  to  monitor  and  report  AEs  and  any  failure  of  a  product  to  meet  the  specifications  in  the  NDA  or  BLA,  as 
applicable. The holder of an approved NDA or BLA must also submit new or supplemental applications and obtain U.S. FDA approval for 
certain  changes  to  the  approved  product,  product  labeling  or  manufacturing  process.  Advertising  and  promotional  materials  must  comply 
with U.S. FDA rules and are subject to U.S. FDA review, in addition to other potentially applicable federal and state laws. 

In  addition,  manufacturers  of  drug  products  and  their  facilities  are  subject  to  payment  of  user  fees  and  continual  review  and  periodic 
inspections  by  the  U.S.  FDA  and  other  regulatory  authorities  for  compliance  with  current  good  manufacturing  practices  (cGMP)  and 
adherence to commitments made in the NDA. If we or a regulatory agency discovers previously unknown problems with a product, such as 
AEs of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose 
restrictions relative to that product or the manufacturing facility, including requiring recall or withdrawal of the product from the market or 
suspension of manufacturing. 

If  we  fail  to  comply  with  applicable  regulatory  requirements  following  approval  of  a  product  candidate,  a  regulatory  agency  may  take  a 
number of actions, including: 

•

•

•

•

•

Issue a warning letter asserting that we are in violation of the law; 

Seek an injunction or impose civil or criminal penalties or monetary fines; 

Suspend or withdraw regulatory approval; 

Suspend any ongoing clinical trials; 

Refuse to approve a pending NDA or supplements to an NDA submitted by us; 

12

 
 
 
  
 
 
 
•

•

Seize product; or 

Refuse to allow us to enter into supply contracts, including government contracts. 

In  particular,  we  may  seek  accelerated  approval  from  the  U.S.  FDA  for  our  product  candidates  which  will  likely  require  a  further 
confirmatory trial. If this confirmatory trial is not successful, we will be required to withdraw our product candidate from the U.S. market and 
potentially other markets. 

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could 
generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our products 
and generate revenue. 

In addition, if any of our product candidates are approved and we are found to have improperly promoted off-label uses of those products, we 
may become subject to significant liability. The U.S. FDA and other regulatory agencies strictly regulate the promotional claims that may be 
made about prescription products, such as our product candidates, if approved. In particular, a product may not be promoted for uses that are 
not  approved  by  the  U.S.  FDA  or  such  other  regulatory  agencies  as  reflected  in  the  product’s  approved  labeling.  If  we  are  found  to  have 
promoted  such  off-label  uses,  we  may  become  subject  to  significant  liability,  which  would  materially  adversely  affect  our  business  and 
financial condition. 

Even if we obtain U.S. FDA approval for our product candidates in the United States, we may never obtain approval to commercialize our 
product candidates outside of the United States, which would limit our ability to realize their full market potential. 

In  order  to  market  any  products  outside  of  the  United  States,  we  must  establish  and  comply  with  numerous  and  varying  regulatory 
requirements  of  other  countries  regarding  safety  and  efficacy.  Clinical  trials  conducted  in  one  country  may  not  be  accepted  by  regulatory 
authorities in other countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other 
country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative 
review periods. 

Seeking foreign regulatory approval could result in difficulties and costs for us and require additional non-clinical studies or clinical trials 
which could be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the 
introduction  of  our  products  in  those  countries.  We  do  not  have  any  product  candidates  approved  for  sale  in  any  jurisdiction,  including 
international  markets,  and  we  do  not  have  experience  in  obtaining  regulatory  approval  in  international  markets.  If  we  fail  to  comply  with 
regulatory  requirements  in  international  markets  or  to  obtain  and  maintain  required  approvals,  or  if  regulatory  approvals  in  international 
markets are delayed, our target market will be reduced and our ability to realize the full market potential of our products will be harmed. 

13

 
 
 
 
 
 
 
We  rely  on  third  parties  to  conduct  our  preclinical  studies  and  clinical  trials.  If  these  third  parties  do  not  successfully  carry  out  their 
contractual  duties  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain  regulatory  approval  for  or  commercialize  our  product 
candidates and our business could be substantially harmed. 

We  have  relied  upon  and  plan  to  continue  to  rely  upon  third-party  CROs  to  conduct  our  preclinical  studies  and  clinical  trials,  including 
investigator-initiated studies sponsored by the investigator’s institution, and control only certain aspects of their activities. Nevertheless, we 
are responsible for ensuring that each of our trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific 
standards and our reliance on the CROs does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with 
U.S. FDA laws and regulations regarding current good clinical practice (cGCP) which are also required by the Competent Authorities of the 
Member  States  of  the  European  Economic  Area  and  comparable  foreign  regulatory  authorities  in  the  form  of  International  Council  for 
Harmonization  (ICH)  guidelines  for  all  of  our  products  in  clinical  development.  Regulatory  authorities  enforce  cGCP  through  periodic 
inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable cGCP, the clinical 
data generated in our clinical trials may be deemed unreliable and the U.S. FDA or comparable foreign regulatory authorities may require us 
to  perform  additional  clinical  trials  before  approving  our  marketing  applications.  We  cannot  assure  you  that  upon  inspection  by  a  given 
regulatory authority, such regulatory authority will determine that any of our clinical trials comply with cGCP regulations. In addition, our 
U.S. clinical trials must be conducted with product produced under cGMP regulations. While we have agreements governing activities of our 
CROs,  we  have  limited  influence  over  their  actual  performance.  In  addition,  portions  of  the  clinical  trials  for  our  product  candidates  are 
expected to be conducted at various locations great distances from where our operations are located in the U.S. and Singapore, which will 
make it more difficult for us to monitor CROs and perform visits of our clinical trial sites and will force us to rely heavily on CROs to ensure 
the  proper  and  timely  conduct  of  our  clinical  trials  and  compliance  with  applicable  regulations,  including  cGCP.  Failure  to  comply  with 
applicable  regulations  in  the  conduct  of  the  clinical  trials  for  our  product  candidates  may  require  us  to  repeat  clinical  trials,  which  would 
delay the regulatory approval process. 

Some  of  our  CROs  have  an  ability  to  terminate  their  respective  agreements  with  us  if,  among  other  reasons,  it  can  be  reasonably 
demonstrated that the safety of the subjects participating in our clinical trials warrants such termination, if we make a general assignment for 
the benefit of our creditors or if we are liquidated. If any of our relationships with these third-party CROs terminate, we may not be able to 
enter into arrangements with alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, 
and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time 
and resources to our preclinical and clinical programs. If CROs do not successfully carry out their contractual duties or obligations or meet 
expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure 
to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated 
and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. Consequently, our results of 
operations and the commercial prospects for our product candidates would be harmed, our costs could increase substantially and our ability 
to generate revenue could be delayed significantly. 

Switching  or  adding  additional  CROs  involves  additional  cost  and  requires  management  time  and  focus.  In  addition,  there  is  a  natural 
transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired 
clinical development timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not 
encounter  challenges  or  delays  in  the  future  or  that  these  delays  or  challenges  will  not  have  a  material  adverse  impact  on  our  business, 
financial condition and prospects. 

14

 
 
 
 
Risks Related to Our Business Operations and Industry 

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel. 

We are highly dependent on the principal members of our executive team, the loss of whose services may adversely impact the achievement 
of  our  objectives.  While  we  have  entered  into  employment  agreements  with  each  of  our  executive  officers,  any  of  them  could  leave  our 
employment at any time, subject to any applicable notice requirements. Recruiting and retaining other qualified employees for our business, 
including scientific and technical personnel, will also be critical to our success. Competition for skilled personnel is intense and the turnover 
rate  can  be  high.  We  may  not  be  able  to  attract  and  retain  personnel  on  acceptable  terms  given  the  competition  among  numerous 
pharmaceutical  companies  for  individuals  with  similar  skill  sets.  In  addition,  failure  to  succeed  in  clinical  studies  may  make  it  more 
challenging to recruit and retain qualified personnel. The inability to recruit or loss of the services of any executive or key employee might 
impede the progress of our development and commercialization objectives. 

We  will  need  to  expand  our  organization,  and  we  may  experience  difficulties  in  managing  this  growth,  which  could  disrupt  our 
operations. 

As  of  December  31,  2022,  we  had  34  full-time  employees.  In  the  future  we  may  expand  our  employee  base  to  increase  our  managerial, 
scientific,  clinical,  operational,  financial  and  other  resources,  to  add  a  sales  and  marketing  function  and  to  hire  more  consultants  and 
contractors. Future growth would impose significant additional responsibilities on our management, including the need to identify, recruit, 
maintain, motivate and integrate additional employees, consultants and contractors. 

Also,  our  management  may  need  to  divert  a  disproportionate  amount  of  its  attention  away  from  our  day-to-day  activities  and  devote  a 
substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, 
which may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and 
reduced  productivity  among  remaining  employees.  Future  growth  could  require  significant  capital  expenditures  and  may  divert  financial 
resources  from  other  projects,  such  as  the  development  of  our  existing  or  future  product  candidates.  If  our  management  is  unable  to 
effectively manage our growth, our expenses may increase more than expected, our ability to generate and grow revenue could be reduced, 
and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize our product
candidates, if approved, and compete effectively will depend, in part, on our ability to effectively manage any future growth. 

The terms of our loan agreements place restrictions on our operating and financial flexibility. If we raise additional capital through debt 
financing, the terms of any new debt could further restrict our ability to operate our business. 

In July 2021, we entered into a loan agreement with K2 HealthVentures LLC (K2HV) and certain parties related to K2HV, pursuant to which 
K2HV agreed to provide a four-year facility for up to $45 million (the K2HV Facility). The K2HV Facility consists of a $20 million initial 
term loan funded at closing, with the remaining $25 million available in tranches subject to certain terms and conditions. In January, 2022, 
the conditions to the second tranche having been satisfied, we drew down the second tranche of $5 million in full and the funds were received 
in  February  2022.  Borrowings  under  the  K2HV  Facility  are  secured  with  a  pledge  of  the  borrowers’  equity  interests  in  subsidiaries  and 
collateral  over  all  of  our  cash,  goods  and  other  personal  property,  with  the  exception  of  (i)  our  registered  intellectual  property  assets,  (ii) 
personal  property  to  the  extent  that  granting  of  security  over  any  such  personal  property  would  constitute  a  breach  of  or  result  in  the 
termination of, or require any consent not obtained under, any license, agreement, instrument or other document evidencing or giving rise to 
such  property,  or  is  otherwise  prohibited  by  any  requirement  of  law,  and  (iii)  our  equity  interests  in  Jaguahr  Therapeutics  Pte.  Ltd 
(JAGUAHR). Such pledge and collateral may be enforced only if there has been an event of default as stipulated in the K2HV Facility. As of 
December 31, 2022, the Company is in full compliance with the K2HV Facility and there have been no events of default.

Borrowings under the K2HV Facility can be used to advance the clinical development of farudodstat, eblasakimab, and general corporate 
purposes. The K2HV Facility includes customary affirmative and negative covenants applicable to us and our subsidiaries, including, among 
other  things,  restrictions  on  indebtedness,  liens,  investments,  mergers,  dispositions,  cash  management,  dividends  and  other  distributions. 
ASLAN Pharmaceuticals Pte. Ltd., a private company limited by shares formed under the laws of the Republic of Singapore, is the guarantor 
of the K2HV Facility. In addition, the K2HV Facility also includes customary events of default, including, but not limited to, failure to pay 
interest, principal and fees or other amounts when due, material misrepresentations or misstatements, covenant defaults, certain cross defaults 
to other material indebtedness, certain judgment defaults and events of bankruptcy or insolvency. Upon the occurrence and continuance of an 
event of default, the lenders may declare all outstanding obligations immediately due and payable and take such other actions as set forth in 
the loan agreement and other loan documents.

If  we  are  liquidated,  the  rights  of  our  lenders  to  repayment  would  be  senior  to  the  rights  of  the  holders  of  our  ordinary  shares  including 
ordinary  shares  represented  by  ADSs  to  receive  any  proceeds  from  the  liquidation.  Any  declaration  by  our  lenders  of  an  event  of  default 
could significantly harm our business and prospects and could cause the price of our ordinary shares and ADSs to decline. If we raise any 
additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility. 

We may face potential product liability, and, if successful claims are brought against us, we may incur substantial liability. 

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approval exposes us to the risk 
of  product  liability  claims.  Product  liability  claims  might  be  brought  against  us  by  consumers,  healthcare  providers,  pharmaceutical 
companies  or  others  selling  or  otherwise  coming  into  contact  with  our  products  and  product  candidates.  If  we  cannot  successfully  defend 
against product liability claims, we could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product 
liability claims may result in:

•

Impairment of our business reputation; 

• Withdrawal of clinical trial participants; 

•

•

•

•

•

Costs due to related litigation; 

Distraction of management’s attention from our primary business; 

Substantial monetary awards to patients or other claimants; 

The inability to commercialize our product candidates; and 

Decreased demand for our product candidates, if approved for commercial sale. 

Our  current  clinical  trial  liability  insurance  coverage  may  not  be  sufficient  to  reimburse  us  for  any  expenses  or  losses  we  may  suffer. 
Moreover, insurance coverage is becoming increasingly expensive and in the future we may not be able to maintain insurance coverage at a 
reasonable cost or in sufficient amounts to protect us against losses due to liability. If and when we obtain marketing approval for our product 
candidates, we intend to expand our insurance coverage to include the sale of commercial products; however, we may be unable to obtain 
product liability insurance on commercially reasonable terms or in adequate amounts. On occasion, large judgments have been awarded in 
class action lawsuits based on drugs that had unanticipated AEs. A successful product liability claim or series of claims brought against us 
could cause the price of our ADSs or ordinary shares to decline and, if judgments exceed our insurance coverage, could adversely affect our 
results of operations and business. 

If  our  information  technology  systems  or  data,  or  those  of  third  parties  upon  which  we  rely,  are  or  were  compromised,  we  could 
experience  adverse  consequences  resulting  from  such  compromise,  including  but  not  limited  to  regulatory  investigations  or  actions; 
litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse 
consequences.

In  the  ordinary  course  of  our  business,  we  and  third  parties  upon  which  we  rely  process  sensitive  data,  and,  as  a  result,  we  and  the  third 
parties upon which we rely face a variety of evolving threats, including, but not limited to ransomware attacks, which could cause security 
incidents.  Cyberattacks,  malicious  internet-based  activity,  online  and  offline  fraud,  and  other  similar  activities  threaten  the  confidentiality, 
integrity, and availability of our sensitive data and information technology systems, and those of the third parties upon which we rely. Such 
threats are prevalent, continue to rise, are becoming increasingly difficult to detect, and come from a variety of sources, including traditional 
computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated 
nation-states, and nation-state-supported actors. 

16

 
 
 
 
 
 
Some  actors  now  engage  and  are  expected  to  continue  to  engage  in  cyber-attacks,  including  without  limitation  nation-state  actors  for 
geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we and 
the third parties upon which we rely may be vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, that could
materially disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our services.

We  and  the  third  parties  upon  which  we  rely  are  subject  to  a  variety  of  evolving  threats,  including  but  not  limited  to  social-engineering 
attacks (including through phishing attacks), malware (including as a result of advanced persistent threat intrusions), personnel misconduct or 
error,  ransomware  attacks,  supply-chain  attacks,  software  bugs,  server  malfunctions,  software  or  hardware  failures,  loss  of  data  or  other 
information technology assets, adware, malicious code (such as viruses and worms), personnel misconduct or error, denial-of-service attacks 
(such as credential stuffing), credential harvesting, telecommunications failures, earthquakes, fires, floods, and other similar threats. 

Ransomware attacks, in particular, including those perpetrated by organized criminal threat actors, nation-states, and nation-state-supported 
actors, are becoming increasingly prevalent and severe and can lead to significant interruptions in our operations, loss of sensitive data and 
income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may 
be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments. 

Remote work has become more common and has increased risks to our information technology systems and data, as more of our employees 
utilize  network  connections,  computers  and  devices  outside  our  premises  or  network,  including  working  at  home,  while  in  transit  and  in 
public locations. Additionally, past or future business transactions (such as acquisitions or integrations) could also expose us to additional 
cybersecurity  risks  and  vulnerabilities,  as  our  systems  could  be  negatively  affected  by  vulnerabilities  present  in  acquired  or  integrated 
entities’ systems and technologies. Furthermore, we may discover security issues that were not found during due diligence of such acquired 
or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program. 

In addition, our reliance on third-party service providers could introduce new cybersecurity risks and vulnerabilities, including supply-chain 
attacks, and other threats to our business operations. We rely on third-party service providers and technologies to operate critical business 
systems to process sensitive data in a variety of contexts, including, without limitation, cloud-based infrastructure, CROs, CMOs, data center 
facilities,  encryption  and  authentication  technology,  employee  email,  content  delivery  to  customers,  and  other  functions.  We  also  rely  on 
third-party service providers to provide other products, services, parts, or otherwise to operate our business. Our ability to monitor these third 
parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. If our 
third-party service providers experience a security incident or other interruption, we could experience adverse consequences. While we may 
be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be 
insufficient to cover our damages, or we may be unable to recover such award. In addition, supply-chain attacks have increased in frequency 
and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or our third-party partners’ supply chains have not 
been compromised.

Any  of  the  previously  identified  or  similar  threats  could  cause  a  security  incident  or  other  interruption  that  could  result  in  unauthorized, 
unlawful, or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of, or access to our sensitive data or our 
information technology systems, or those of the third parties upon whom we rely. A security incident or other interruption could disrupt our 
ability (and that of third parties upon whom we rely) to provide our services. 

We may expend significant resources or modify our business activities to try to protect against security incidents. Additionally, certain data 
privacy  and  security  obligations  may  require  us  to  implement  and  maintain  specific  security  measures  or  industry-standard  or  reasonable 
security measures to protect our information technology systems and sensitive data.

17

 
 
 
 
 
 
 
 
While we have security measures designed to protect against security incidents and detect vulnerabilities, there can be no assurance that these 
measures  will  be  effective.  We  take  steps  to  detect  and  remediate  vulnerabilities,  but  we  may  not  be  able  to  detect  and  remediate  all 
vulnerabilities because the threats and techniques used to exploit the vulnerability change frequently and are often sophisticated in nature. 
Therefore, such vulnerabilities could be exploited but may not be detected until after a security incident has occurred. These vulnerabilities 
pose material risks to our business. Further, we may experience delays in developing and deploying remedial measures designed to address 
any such identified vulnerabilities. 

Applicable data protection laws, privacy policies and data protection obligations may require us to notify relevant stakeholders of security 
incidents or other unauthorized disclosure or access of data. Such disclosures are costly, and the disclosures or the failure to comply with 
such requirements could lead adverse consequences. 

If we (or a third party upon whom we rely) experience a security incident, or are perceived to have experienced a security incident, we may 
experience  adverse  consequences.  These  consequences  may  include:  government  enforcement  actions  (for  example,  investigations,  fines, 
penalties,  audits,  and  inspections);  additional  reporting  requirements  and/or  oversight;  restrictions  on  processing  sensitive  data  (including 
personal  data);  litigation  (including  class  claims);  indemnification  obligations;  negative  publicity;  reputational  harm;  monetary  fund 
diversions; interruptions to our operations (including availability of data); financial loss; and other similar harms. For example, the loss of 
clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase 
our costs to recover or reproduce the data. 

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that the limitations of liability in our 
contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages, or claims if we fail to comply with 
applicable data privacy and security obligations. 

In addition to experiencing a security incident, third parties may gather, collect, or infer sensitive information about us from public sources, 
data  brokers,  or  other  means  that  reveals  competitively  sensitive  details  about  our  organization  and  could  be  used  to  undermine  our 
competitive advantage or market position.

Our operations could be subject to natural disasters, health pandemics or epidemics and other business disruptions, which could have a 
material adverse effect on our business, results of operation and financial condition. 

Some  of  our  operations,  including  in  particular  some  of  our  clinical  trials,  are  being  conducted  across  areas  that  may  be  prone  to  natural 
disasters, such as earthquakes, cyclones, monsoons and floods, which could cause interruptions to our operations. We do not have a disaster 
recovery or business continuity plan in place to cover such natural disasters and may incur substantial expenses as a result of the absence or 
limited nature of our internal or third-party service providers’ disaster recovery and business continuity plans, which could have a material 
adverse effect on our business. 

Any occurrence of these natural disasters or pandemic diseases or other adverse public health developments in the areas in which we operate 
our  clinical  trials  could  disrupt  or  delay  our  business  operations  or  clinical  development,  which  could  materially  adversely  affect  our 
business. 

Our business could continue to be adversely affected by the effects of health pandemics or epidemics, including the effects of the COVID-
19 pandemic.

Our business could continue to be adversely affected by the effects of health pandemics or epidemics, including the effects of the COVID-19 
pandemic, and other recent outbreaks of diseases, such influenza A, avian influenza, and severe acute respiratory syndrome. The COVID-19 
pandemic  resulted  in  travel  restrictions,  quarantine  orders  and  other  restrictions  by  governments  to  reduce  the  spread  of  the  disease.  The 
effects of restrictions imposed in the event of a reoccurrence of the COVID-19 pandemic or of other health pandemics or epidemics, and our 
related  workplace  policies,  may  negatively  impact  productivity,  disrupt  our  business  and  delay  our  clinical  programs  and  timelines,  the 
magnitude  of  which  will  depend,  in  part,  on  the  length  and  severity  of  the  restrictions  and  other  limitations  on  our  ability  to  conduct  our 
business  in  the  ordinary  course.  These  and  similar,  and  perhaps  more  severe,  disruptions  in  our  operations  could  negatively  impact  our 
business, operating results and financial condition.

18

 
 
 
 
 
 
 
 
 
 
Quarantines,  shelter-in-place  and  similar  government  orders,  or  the  perception  that  such  orders,  shutdowns  or  other  restrictions  on  the 
conduct  of  business  operations  could  occur,  related  to  COVID-19  or  other  infectious  diseases  could  impact  personnel  at  third-party 
manufacturing facilities, or the availability or cost of materials, which would disrupt our supply chain. While many of these materials may be 
obtained by more than one supplier, port closures and other restrictions resulting from the coronavirus outbreak in the region or other regions 
may disrupt our supply chain or limit our ability to obtain sufficient materials for our product candidates. 

In addition, our clinical trials have been affected by the COVID-19 pandemic. Site initiation and patient enrollment has been, and if there is a 
reoccurrence of the pandemic may be further, delayed due to prioritization of hospital resources toward the pandemic, and some patients may 
not  be  able  or  willing  to  comply  with  clinical  trial  protocols  if  quarantines  impede  patient  movement  or  interrupt  healthcare  services. 
Similarly, if there is a reoccurrence of the pandemic, our ability to recruit and retain patients and principal investigators and site staff who, as 
healthcare providers, may have heightened exposure to COVID-19, may be delayed or disrupted. 

The  COVID-19,  which  has  caused  a  broad  impact  globally,  may  materially  affect  us  economically.  While  the  potential  economic  impact 
brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, the pandemic has caused disruption of global 
financial markets.  This disruption, if sustained or recurrent, could make it more difficult for us to access capital, which could in the future 
negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect 
our business and the value of our ADSs.

The effects of the COVID-19 pandemic continue to evolve. The ultimate impact of the COVID-19 pandemic or a similar health pandemic or 
epidemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our 
clinical trials, healthcare systems or the global economy as a whole. These effects could have a material impact on our operations, or the 
operations of third parties on whom we rely.

Our business is subject to economic, political, regulatory and other risks associated with international operations. 

As a company with significant operations in Singapore, our business is subject to risks associated with conducting business outside of the 
United States. Many of our suppliers and collaborative and clinical trial relationships are located outside the United States. Accordingly, our 
future results could be harmed by a variety of factors, including: 

•

•

•

•

•

•

•

•

•

•

•

•

Economic weakness, including inflation, or political instability; 

Differing and changing regulatory requirements for drug approvals; 

Differing  jurisdictions  could  present  different  issues  for  securing,  maintaining  or  obtaining  freedom  to  operate  in  such 
jurisdictions; 

Potentially reduced protection for intellectual property rights; 

Difficulties in compliance with local laws and regulations; 

Changes in local regulations and customs, tariffs and trade barriers;  

Changes in currency exchange rates, including the Singapore dollar;

Changes in macroeconomic conditions or a specific country’s or region’s political or economic environment, including bank 
failures;    

Trade protection measures, import or export licensing requirements or other restrictive actions; 

Differing reimbursement regimes and price controls; 

Negative consequences from changes in tax laws; 

Compliance with tax, employment, immigration and labor laws for employees; 

• Workforce uncertainty in countries where labor unrest is more common than in the United States; 

•

Difficulties associated with staffing and managing international operations, including differing labor relations; 

19

 
 
 
 
 
•

•

•

Production shortages resulting from any events affecting raw material supply or manufacturing capabilities; 

Disruptions  on  us  or  our  strategic  partners,  third-party  manufacturers,  suppliers  and  other  third  parties  upon  which  we  rely 
resulting from the impact of public health epidemics or pandemics (including, for example, the COVID-19 pandemic); and

Business  interruptions  resulting  from  geo-political  actions,  including  war,  such  as  the  ongoing  conflict  between  Russia  and 
Ukraine, and terrorism, or natural disasters including typhoons, floods and fires. 

We are subject to stringent and changing U.S. and foreign laws, regulations, rules, contractual obligations, policies obligations related to 
data  privacy  and  security.  Our  actual  or  perceived  failure  to  comply  with  such  obligations  could  lead  to  regulatory  investigations  or 
actions;  litigations;  fines  and  penalties;  a  disruption  of  our  business  operations;  reputational  harm;  and  other  adverse  business 
consequences. 

In the ordinary course of business, we collect, receive, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, 
share and store (collectively, processing) personal data and other sensitive data, including proprietary and confidential business data, trade 
secrets, intellectual property, data we collect about trial participants in connection with clinical trials, sensitive third-party data, and employee 
and patient data (collectively, sensitive data). 

Our data processing activities may subject us to numerous data privacy and security obligations, such as various laws, regulations, guidance, 
industry standards, external and internal privacy and security policies, contractual requirements, and other obligations relating to data privacy 
and security.

In  the  United  States,  federal,  state,  and  local  governments  have  enacted  numerous  data  privacy  and  security  laws,  including  health 
information  privacy  laws,  data  breach  notification  laws,  personal  data  privacy  laws,  and  consumer  protection  laws  (e.g.,  Section  5  of  the 
Federal Trade Commission Act), and other similar laws (e.g., wiretapping laws). For example, the federal Health Insurance Portability and 
Accountability Act of 1996 (HIPAA), as amended by the Health Information Technology for Economic and Clinical Health Act (HITECH), 
imposes  specific  requirements  relating  to  the  privacy,  security,  and  transmission  of  individually  identifiable  health  data.  In  addition,  the 
California Consumer Privacy Act of 2018 (CCPA) applies to personal information of consumers, business representatives, and employees, 
and  requires  businesses  to  provide  specific  disclosures  in  privacy  notices  and  honor  requests  of  California  residents  to  exercise  certain 
privacy rights. The CCPA provides for civil penalties up to $7,500 per violation and allows private litigants affected by certain data breaches
to recover significant statutory damages. Although the CCPA exempts some data processed in the context of clinical trials, the CCPA may 
increase compliance costs and potential liability with respect to other personal data we maintain about California residents. In addition, the 
California  Privacy  Rights  Act  of  2020  (CPRA)  expands  the  CCPA’s  requirements,  for  example  by  establishing  a  new  California  Privacy 
Protection Agency to implement and enforce the law and adding a new right for individuals to correct their personal information. 

Other states, such as Virginia and Colorado, have also passed comprehensive privacy laws, and similar laws are being considered in several 
other states as well as at the federal and local levels. While these states, like the CCPA, also exempt some data processed in the context of 
clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us and the third 
parties upon whom we rely. 

Outside  the  United  States,  an  increasing  number  of  laws,  regulations,  and  industry  standards  may  govern  data  privacy  and  security.  For 
example, because we are headquartered in Singapore, we may be subject to Singapore’s Personal Data Protection Act of 2012 (PDPA), which 
generally requires covered organizations to provide notice and obtain consents prior to the collection, use, or disclosure of personal data. The 
PDPA  also  provides  individuals  with  certain  rights  regarding  their  personal  data  and  imposes  certain  compliance  obligations  related  to 
accountability, protection, transfer, and permitted uses of personal data. 

Additionally,  foreign  jurisdictions  have  enacted  statutes  imposing  strict  requirements  for  processing  personal  data.  such  as  the  European 
Union’s  General  Data  Protection  Regulation  (EU  GDPR),  the  United  Kingdom’s  GDPR  (UK  GDPR),  and  Canada’s  Personal  Information 
Protection and Electronic Documents Act (PIPEDA). 

For example, under the EU GDPR, companies may face temporary or definitive bans on data processing, other corrective actions, fines of up 
to 20 million Euros or 4% of annual global revenue, whichever is greater, or private litigation related to processing of personal data brought 
by classes of data subject or consumer protection groups authorized at law to represent their interests.

20

 
 
 
 
 
 
 
 
In addition, we may be unable to transfer personal data from Europe and other jurisdictions to the United States or other countries due to data 
localization requirements or limitations on cross-border data flows.  Europe and other jurisdictions have enacted laws requiring data to be 
localized  or  limiting  the  transfer  of  personal  data  to  other  countries.  In  particular,  the  European  Economic  Area  (EEA)  and  the  United 
Kingdom  (UK)  have  significantly  restricted  the  transfer  of  personal  data  to  the  United  States  and  other  countries  whose  privacy  laws  it 
believes  are  inadequate.  Other  jurisdictions  may  adopt  similarly  stringent  interpretations  of  their  data  localization  and  cross-border  data 
transfer  laws.  Although  there  are  currently  various  mechanisms  that  may  be  used  to  transfer  personal  data  from  the  EEA  and  UK  to  the 
United  States  in  compliance  with  law,  such  as  the  EEA  and  UK’s  standard  contractual  clauses,  these  mechanisms  are  subject  to  legal 
challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States. If 
there  is  no  lawful  manner  for  us  to  transfer  personal  data  from  the  EEA,  the  UK,  or  other  jurisdictions  to  the  United  States,  or  if  the 
requirements for a legally-compliant transfer are too onerous, we may face significant adverse consequences, including the interruption or 
degradation  of  our  operations,  the  need  to  relocate  part  of  or  all  of  our  business  or  data  processing  activities  to  other  jurisdictions  at 
significant  expense,  increased  exposure  to  regulatory  actions,  substantial  fines  and  penalties,  the  inability  to  transfer  data  and  work  with 
partners, vendors, and other third parties, and injunctions against our processing or transferring of personal data  necessary to operate our 
business.  Additionally, companies that transfer personal data out of the EEA and UK to other jurisdictions, particularly to the United States, 
are  subject  to  increased  scrutiny  from  regulators,  individual  litigants,  and  activist  groups.  Some  European  regulators  have  ordered  certain 
companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the EU GDPR’s and/or the UK GDPR’s 
cross-border data transfer limitations. 

In addition to data privacy and security laws, we are contractually subject to industry standards adopted by industry groups and may become 
subject  to  such  obligations  in  the  future.  We  are  also  bound  by  other  contractual  obligations  related  to  data  privacy  and  security,  and  our 
efforts to comply with such obligations may not be successful.  

Obligations related to data privacy and security are quickly changing, becoming increasingly stringent, and creating regulatory uncertainty. 
Additionally,  these  obligations  may  be  subject  to  differing  applications  and  interpretations,  which  may  be  inconsistent  or  conflict  among 
jurisdictions. Preparing for and complying with these obligations requires us to devote significant resources, which may necessitate changes 
to our services, information technologies, systems, and practices and to those of any third parties that process personal data on our behalf. 

We  may  at  times  fail  (or  be  perceived  to  have  failed)  in  our  efforts  to  comply  with  our  data  privacy  and  security  obligations.  Moreover, 
despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact 
our business operations. If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable 
data privacy and security obligations we could face significant consequences, including but not limited to: government enforcement actions 
(e.g.,  investigations,  fines,  penalties,  audits,  inspections,  and  similar),  ligation  (including  class-action  claims),  additional  reporting 
requirements  and/or  oversight,  orders  to  destroy  or  not  use  personal  data,  the  inability  to  process  sensitive  data,  regulatory  scrutiny, 
disruptions to our operations (including our ability to conduct clinical trials), diversion of time and effort, and/or adverse publicity and could 
negatively affect our operating results and business. Any of these events could have a material adverse effect on our reputation, business, or 
financial  condition,  including  but  not  limited  to:  loss  of  customers;  interruptions  or  stoppages  in  our  business  operations  (including,  as 
relevant, clinical trials); inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize 
our  products;  expenditure  of  time  and  resources  to  defend  any  claim  or  inquiry;  adverse  publicity;  or  substantial  changes  to  our  business 
model or operations.   

21

 
 
 
 
 
Risks Related to Our Intellectual Property 

If  we  are  unable  to  obtain  or  protect  intellectual  property  rights  related  to  our  current  product  candidates  or  any  future  product 
candidates which we may develop, we may not be able to compete effectively in our market. 

We  rely  upon  a  combination  of  patents,  trade  secret  protection,  confidentiality  agreements  and  proprietary  know-how,  and  intend  to  seek 
marketing  exclusivity  for  any  approved  product,  in  order  to  protect  the  intellectual  property  related  to  product  candidates.  The  patent 
prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license all 
necessary  or  desirable  patent  applications  at  a  reasonable  cost  or  in  a  timely  manner.  The  strength  of  patents  in  the  biotechnology  and 
pharmaceutical  field  involves  complex  legal  and  scientific  questions,  is  highly  uncertain,  and  has,  in  the  recent  years,  been  the  subject  of 
much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. The 
patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates in the United 
States or in other foreign countries for a number of reasons, including because of a finding of lack of novelty or that the claimed inventions 
are already in the public domain. If this were to occur, early competition from third parties could be expected against our product candidates. 

Even  if  patents  do  successfully  issue,  third  parties  may  challenge  their  validity,  enforceability  or  scope,  which  may  result  in  such  patents 
being invalidated, rendered unenforceable, narrowed or deemed as not infringing. Also, a third party may challenge our ownership of patents 
and patent applications assigned to us, or may challenge our exclusive rights to patents and patent applications that we license from third 
parties. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property 
or prevent others from circumventing our patents by developing products similar to or competing with our product candidates. If the patent 
applications we hold with respect to our product candidates fail to issue or if their breadth or strength of protection is threatened, it could 
dissuade companies from collaborating with us to develop them, and threaten our ability to commercialize any resulting products. We cannot 
offer any assurances about which, if any, applications will issue as patents or whether any issued patents will be found not invalid and not 
unenforceable  or  will  go  unthreatened  by  third  parties.  In  addition,  due  to  the  amount  of  time  required  for  the  development,  testing  and 
regulatory  review  of  new  product  candidates,  patents  protecting  such  candidates  might  expire  before  or  shortly  after  such  candidates  are 
commercialized. Furthermore, patent applications by third parties can result in an interference proceeding in the United States being invoked 
by a third party or instituted by us to determine who was the first to invent any of the subject matter covered by the patent claims of our 
applications or patents. 

Because patent applications in the United States, Europe and many other jurisdictions are typically not published until 18 months after filing, 
and because publications of discoveries in scientific literature lag behind actual discoveries, we cannot be certain that we were the first to 
make  the  inventions  claimed  in  our  issued  patents  or  pending  patent  applications,  or  that  we  were  the  first  to  file  for  protection  of  the 
inventions  set  forth  in  our  patents  or  patent  applications.  As  a  result,  we  may  not  be  able  to  obtain  or  maintain  protection  for  certain 
inventions.  Therefore,  the  enforceability  and  scope  of  our  patents  in  the  United  States,  Europe  and  in  many  other  jurisdictions  cannot  be 
predicted with certainty and, as a result, any patents that we own or license may not provide sufficient protection against competitors. We 
may not be able to obtain or maintain patent protection from our pending patent applications, from those we may file in the future, or from 
those  we  may  license  from  third  parties.  Moreover,  even  if  we  are  able  to  obtain  patent  protection,  such  patent  protection  may  be  of 
insufficient scope to achieve our business objectives. 

Moreover, some of our owned patents and patent applications are, and may in the future be, co-owned with third parties. For example, under 
our  license  agreement  with  CSL  Limited  (CSL)  we  and  CSL  co-own  certain  intellectual  property  that  we  jointly  developed  prior  to  the 
completion of the single ascending dose clinical trial for eblasakimab. While we currently have an exclusive license to CSL’s rights under 
such  co-owned  intellectual  property,  if  we  are  unable  to  maintain  such  exclusive  license,  or  if  we  are  unable  to  obtain  and  maintain  an 
exclusive license to any of our other third-party co-owners’ rights under any intellectual property that we co-own, such co-owners may be 
able  to  license  their  rights  to  other  third  parties,  including  our  competitors,  and  our  competitors  could  market  competing  products  and 
technology. In addition, we may need the cooperation of any such co-owners of our patents in order to license and/or enforce such patents 
against  third  parties,  and  such  cooperation  may  not  be  provided  to  us.  Any  of  the  foregoing  could  have  a  material  adverse  effect  on  our 
competitive position, business, financial conditions, results of operations, and prospects. 

22

 
 
 
 
 
 
Our inability to protect our confidential information and trade secrets would harm our business and competitive position. 

In  addition  to  the  protection  afforded  by  patents,  we  rely  on  trade  secret  protection  and  confidentiality  agreements  to  protect  proprietary 
know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our drug development process 
that involve proprietary know-how, information or technology that is not covered by patents. Trade secrets can be difficult to protect. We 
seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to 
them, such as our employees, corporate collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors, 
and other third parties. We cannot guarantee that we have entered into such agreements with each party that may have or have had access to 
our trade secrets or proprietary technology and processes. Despite these efforts, any of these parties may breach the agreements and disclose 
our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Furthermore, 
we cannot guarantee that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not 
otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. If we are unable to 
prevent material disclosure of the non-patented intellectual property related to our technologies to third parties, and there is no guarantee that 
we will have any such enforceable trade secret protection, we may not be able to establish or maintain a competitive advantage in our market, 
which could materially adversely affect our business, results of operations and financial condition. 

We may not be able to protect our intellectual property and proprietary rights throughout the world. 

Filing, prosecuting, and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and 
the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Consequently, we may not be able 
to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made 
using our inventions in and into the United States or other jurisdictions. 

Competitors  may  use  our  technologies  in  jurisdictions  where  we  have  not  obtained  patent  protection  to  develop  their  own  products  and, 
further, may export otherwise infringing products to territories where we have patent protection but enforcement is not as strong as that in the 
United States. These products may compete with our products, and our patents or other intellectual property rights may not be effective or 
sufficient to prevent them from competing. If we are unable to block the commercialization of these products, these products may erode our 
commercial position in the market place. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The 
legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other 
intellectual property rights, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in 
violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property and proprietary rights 
in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our 
patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third 
parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, 
may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world 
may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. 

Several countries have compulsory licensing laws under which, in certain circumstances, a patent owner may be compelled to grant licenses 
to third parties on low or no compensation. In addition, many countries limit the enforceability of patents against government agencies or 
government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such 
patent.  If  we  or  any  of  our  licensors  is  forced  to  grant  a  license  to  third  parties  with  respect  to  any  patents  relevant  to  our  business,  our 
competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected. 

23

 
 
 
 
 
 
If we fail to comply with our obligations in the agreements under which we license rights to technology from third parties, or if the license 
agreements are terminated for other reasons, we could lose license rights that are important to our business. 

We are heavily reliant upon licenses to certain patent rights and proprietary technology from third parties that are important or necessary to 
the development of our product candidates. Accordingly, we are party to a number of technology licenses that are important to our business 
and  expect  to  enter  into  additional  licenses  in  the  future.  For  example,  our  rights  to  eblasakimab  are  the  subject  of  an  exclusive  license 
agreement with CSL. If we fail to comply with our obligations under our agreement with CSL (including, among other things, if we fail to 
develop and commercialize eblasakimab in a proper, efficient, skillful, diligent and competent manner) or our other license agreements, or 
we are subject to insolvency or liquidation, our licensors may have the right to terminate the license. 

In addition, under our agreement with CSL, in the event of a change of control, we are required to receive CSL’s prior consent to engage in 
such  a  transaction  if  the  change  of  control,  in  CSL’s  reasonable  opinion,  adversely  affects  our  ability  to  carry  out  the  development  of 
eblasakimab or would damage CSL’s reputation. A breach of this obligation may result in termination of the license. In the event that any of 
our important technology licenses were to be terminated by the licensor, we may need to negotiate new or reinstated agreements, which may 
not  be  available  to  us  on  equally  favorable  terms,  or  at  all,  or  we  could  lose  our  rights  under  these  agreements,  including  our  rights  to 
intellectual property or technology important to our development programs, which would likely cause us to cease further development of the 
related  program,  including eblasakimab.  Furthermore,  under  certain  of  our  collaboration  agreements,  our  licensors  may  retain  the  right  to 
grant non-exclusive licenses to the licensed patents and technology to other academic or research institutions for non-commercial research 
purposes, in which case we would not have exclusive rights to such licensed patents and technologies. 

Our technology agreements under which we currently license intellectual property or technology to and from third parties are complex and 
certain  provisions  in  such  agreements  may  be  susceptible  to  multiple  interpretations.  The  resolution  of  any  contract  interpretation 
disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, 
increase what we believe to be our financial or other obligations under the relevant agreement or decrease the third party’s financial or other 
obligations under the relevant agreement, any of which could have a material adverse effect on our business, financial condition, results of 
operations and prospects. 

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

•

•

•

•

•

•

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

The  extent  to  which  our  technology  and  processes  infringe  on  intellectual  property  of  the  licensor  that  is  not  subject  to  the 
licensing agreement; 

The sublicensing of patent and other rights under our existing collaborative development relationships and any collaboration 
relationships we might enter into in the future; 

Our diligence obligations under the license agreement and what activities satisfy those diligence obligations; 

The inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by 
our current and future licensors and us; and 

The priority of invention of patented technology. 

We  are  generally  also  subject  to  all  of  the  same  risks  with  respect  to  protection  of  intellectual  property  that  we  license,  as  we  are  for 
intellectual property that we own, which are described elsewhere under “Risks Related to Our Intellectual Property.” If we or our licensors 
fail to adequately protect this intellectual property, our ability to commercialize products could suffer. Moreover, if disputes over intellectual 
property  that  we  have  licensed  prevent  or  impair  our  ability  to  maintain  our  current  licensing  arrangements  on  commercially  acceptable 
terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse 
effect on our business, financial conditions, results of operations, and prospects. 

24

 
 
 
 
 
Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts. 

Our  commercial  success  depends  in  part  on  our  avoiding  infringement  of  the  patents  and  proprietary  rights  of  third  parties.  There  is  a 
substantial  amount  of  litigation,  both  within  and  outside  the  United  States,  involving  patent  and  other  intellectual  property  rights  in  the 
biotechnology  and  pharmaceutical  industries,  including  patent  infringement  lawsuits,  interferences,  oppositions,  reexamination,  post-grant 
review, inter partes review, and derivation proceedings before the U.S. Patent and Trademark Office (USPTO), and equivalent proceedings in 
foreign  jurisdictions  (e.g.,  opposition  proceedings).  Numerous  U.S.  and  foreign  issued  patents  and  pending  patent  applications  which  are 
owned by third parties, exist in the fields in which we and our collaborators are developing product candidates. As the biotechnology and 
pharmaceutical  industries  expand  and  more  patents  are  issued,  the  risk  increases  that  our  product  candidates  may  be  subject  to  claims  of 
infringement of the patent rights of third parties. 

Third parties may assert that we or our product candidates are infringing, misappropriating or otherwise violating their intellectual property 
without authorization. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture 
or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to 
issue, there may be currently pending patent applications which may later result in issued patents that our product candidates may infringe. 

In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-
party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our product candidates, any drug 
substance  formed  during  the  manufacturing  process  or  any  final  product  itself,  the  holders  of  any  such  patents  may  be  able  to  block  our 
ability  to  commercialize  such  product  candidate  unless  we  obtain  a  license  under  the  applicable  patents,  which  may  not  be  available  on 
commercially reasonable terms or at all, or until such patents are invalidated or expire. Similarly, if any third-party patent were held by a 
court of competent jurisdiction to cover aspects of our formulations or methods of use, the holders of any such patent may be able to block 
our ability to develop and commercialize the applicable product candidate formulation or use unless we obtain a license, which may not be 
available  on  commercially  reasonable  terms  or  at  all,  or  until  such  patent  expires.  In  either  case,  such  a  license  may  not  be  available  on 
commercially reasonable terms or at all. 

Parties making intellectual property claims against us may request and/or obtain injunctive or other equitable relief, which could effectively 
block our ability to further develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their 
merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. Even if we 
believe any third-party intellectual property claims are without merit, there is no assurance that a court would find in our favor on questions 
of validity, enforceability, priority, or non-infringement. In the event of a successful claim of infringement against us, we may have to pay 
substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, 
pay  royalties  or  redesign  our  infringing  products  or  manufacturing  processes,  which  may  be  impossible  or  require  substantial  time  and 
monetary  expenditure.  We  cannot  predict  whether  any  such  license  would  be  available  at  all  or  whether  it  would  be  available  on 
commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance 
our research, manufacture clinical trial supplies or allow commercialization of our product candidates. The licensing or acquisition of third-
party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license or acquire 
third-party  intellectual  property  rights  that  we  may  consider  attractive  or  necessary.  These  established  companies  may  have  a  competitive 
advantage  over  us  due  to  their  size,  capital  resources  and  greater  clinical  development  or  commercialization  capabilities.  In  addition, 
companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We may fail to obtain any of these licenses at 
a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our 
product  candidates,  which  could  harm  our  business  significantly.  We  cannot  provide  any  assurances  that  third-party  patents  do  not  exist 
which  might  be  enforced  against  our  products,  resulting  in  either  an  injunction  prohibiting  our  sales,  or,  with  respect  to  our  sales,  an 
obligation on our part to pay royalties and/or other forms of compensation to third parties. 

25

 
 
 
 
 
We  may  be  involved  in  lawsuits  to  protect  or  enforce  our  patents  or  the  patents  of  our  licensors,  which  could  be  expensive,  time 
consuming and unsuccessful. 

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required to file 
infringement claims, which can be expensive and time-consuming. If we or one of our licensors were to initiate legal proceedings against a 
third party to enforce a patent covering one of our products, the defendant could counterclaim that such patent is invalid or unenforceable. In 
patent  litigation  in  the  United  States  or  in  Europe,  defendant  counterclaims  alleging  invalidity  or  unenforceability  are  commonplace.  In 
addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, may narrow 
the scope of our or our licensor’s patents, or may refuse to stop the defendant from using the technology at issue on the grounds that our 
patents  do  not  cover  the  technology  in  question.  An  adverse  result  in  any  litigation  or  defense  proceedings  could  put  one  or  more  of  our 
patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. 

Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with respect to 
our  patents  or  patent  applications  or  those  of  our  collaborators  or  licensors.  An  unfavorable  outcome  could  require  us  to  cease  using  the 
related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not 
offer us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if successful, 
may result in substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our licensors, 
misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the 
United States. 

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that 
some  of  our  confidential  information  could  be  compromised  by  disclosure  during  this  type  of  litigation.  There  could  also  be  public 
announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive 
these results to be negative, it could have a material adverse effect on the price of our ADSs. 

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates. 

Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity and is therefore costly, 
time-consuming and inherently uncertain. Changes in either the patent laws or interpretation of the patent laws in the United States could 
increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  patent  applications  and  the  enforcement  or  defense  of  issued  patents. 
Recent patent reform legislation in the United States and other countries, including the Leahy-Smith America Invents Act (Leahy-Smith Act), 
could increase those uncertainties and costs. The Leahy-Smith Act includes provisions that affect the way patent applications are prosecuted, 
redefine  prior  art  and  provide  more  efficient  and  cost-effective  avenues  for  competitors  to  challenge  the  validity  of  patents,  and  may  also 
affect  patent  litigation.  These  include  allowing  third-party  submission  of  prior  art  to  the  USPTO  during  patent  prosecution  and  additional 
procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review 
and derivation proceedings. In addition, assuming that other requirements for patentability are met, prior to March 15, 2013, in the United 
States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application 
was entitled to the patent. After March 15, 2013, under the Leahy-Smith Act, the United States transitioned to a first inventor to file system in 
which, assuming that the other statutory requirements are met, the first inventor to file a patent application will be entitled to the patent on an 
invention  regardless  of  whether  a  third  party  was  the  first  to  invent  the  claimed  invention.  However,  the  Leahy-Smith  Act  and  its 
implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  patent  applications  and  the  enforcement  or 
defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and 
prospects. 

26

 
 
 
 
 
 
In  addition,  the  U.S.  Supreme  Court  has  ruled  on  several  patent  cases  in  recent  years,  either  narrowing  the  scope  of  patent  protection 
available  in  certain  circumstances  or  weakening  the  rights  of  patent  owners  in  certain  situations.  This  combination  of  events  has  created 
uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the 
U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in 
unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in 
the future. 

Obtaining  and  maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee  payment 
and  other  requirements  imposed  by  governmental  patent  agencies,  and  our  patent  protection  could  be  reduced  or  eliminated  for  non-
compliance with these requirements. 

Periodic  maintenance  fees  on  any  issued  patent  are  due  to  be  paid  to  the  USPTO  and  foreign  patent  agencies  in  several  stages  over  the 
lifetime  of  the  patent.  The  USPTO  and  various  foreign  governmental  patent  agencies  require  compliance  with  a  number  of  procedural, 
documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases 
be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can 
(i)  result  in  abandonment  or  lapse  of,  or  (ii)  otherwise  affect  the  patentability  of,  the  patent  or  patent  application,  resulting  in  partial  or 
complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or 
patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and 
failure to properly legalize and submit formal documents. If we or our licensors that control the prosecution and maintenance of our licensed 
patents  fail  to  maintain  the  patents  and  patent  applications  covering  our  product  candidates,  our  competitors  might  be  able  to  enter  the 
market, which would have a material adverse effect on our business. 

In addition, as licensees we may not be responsible for or have control over the prosecution or enforceability of our licensed patents. In such 
cases, we have to rely on the licensor to comply with the requisite obligations of the patent offices, including the duty of disclosure, filing 
assignments,  etc.  We  cannot  guarantee  that  our  licensed  patents  and  patent  applications  will  be  prosecuted,  maintained  and  enforced  in  a 
manner  consistent  with  the  best  interests  of  our  business.  As  licensees,  we  may  not  be  in  a  position  to  assess  if  these  duties  have  been 
complied with or have the ability to complete these duties on behalf of the licensor. Failure by our licensors to comply with such duties may 
affect  the  enforceability  of  the  patent  rights,  narrow  the  scope  of  our  patent  protection  and,  more  generally,  could  affect  the  value  of  our 
patent  rights.  If  our  patent  protection  is  reduced  or  eliminated,  we  may  not  be  able  to  prevent  our  competitors  or  other  third  parties  from 
developing or commercializing products similar to ours and may be required to cease development of our product candidates, which could 
have a material adverse effect on our business.

If we do not obtain patent term extension for any product candidates we may develop, our business may be materially harmed. 

Depending upon the timing, duration and specifics of any U.S. FDA marketing approval of any product candidates we may develop, one or 
more of our owned or in-licensed U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent 
Term Restoration Act of 1984 (Hatch-Waxman Amendments). The Hatch-Waxman Amendments permit a patent term extension of up to five 
years as compensation for the patent term lost during the U.S. FDA regulatory review process. A patent term extension cannot extend the 
remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those 
claims  covering  the  approved  drug,  a  method  for  using  it  or  a  method  for  manufacturing  it  may  be  extended.  However,  we  may  not  be 
granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing 
to  apply  within  applicable  deadlines,  failing  to  apply  prior  to  expiration  of  relevant  patents,  or  otherwise  failing  to  satisfy  applicable 
requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. Similar issues 
apply in the patent legal systems of other key markets such as the EU. If we are unable to obtain patent term extension or the term of any 
such extension is less than we request, our competitors may obtain approval of competing products following our patent expiration, and our 
business, financial condition, results of operations and prospects could be materially harmed. 

27

 
 
 
  
 
 
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential 
information of third parties. 

We  employ  individuals,  and  work  with  consultants  or  independent  contractors,  who  were  previously  employed  at  other  biotechnology  or 
pharmaceutical  companies,  including  our  competitors  or  potential  competitors.  We  may  be  subject  to  claims  that  we  or  our  employees, 
consultants or independent contractors have inadvertently or otherwise used or disclosed confidential information, including trade secrets, of 
any such individual’s former employers or other third parties. We may also be subject to claims that former employers or other third parties 
have an ownership interest in our patents. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, 
in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. There is no guarantee of success in 
defending these claims, and even if we are successful, litigation could result in substantial cost and be a distraction to our management and 
other employees. 

In addition, while it is our policy to require our employees, consultants and independent contractors who may be involved in the conception 
or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing 
such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of 
intellectual property rights may not be self-executing (and may require further action), or the assignment agreements may be breached, and 
we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what 
we  regard  as  our  intellectual  property.  Such  claims  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of 
operations, and prospects. 

If our trademarks and tradenames are not adequately protected, then we may not be able to build name recognition in our markets and 
our business may be adversely affected. 

We have registered or applied to register certain trademarks to protect our company name and plan to apply to register trademarks to cover 
product  names  in  the  future  once  our  product  candidates  are  closer  to  commercialization.  We  cannot  assure  you  that  our  trademark 
applications will be approved or that we will seek registered trademark protection for each of our product names in each jurisdiction in which 
we operate. During trademark registration proceedings, we may receive rejections. Although we are given an opportunity to respond to those 
rejections,  we  may  be  unable  to  overcome  such  rejections.  In  addition,  in  proceedings  before  the  USPTO  and  in  proceedings  before 
comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to 
seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may 
not survive such proceedings. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products, which 
could result in loss of brand recognition and could require us to devote resources toward advertising and marketing new brands. Further, we 
cannot assure you that competitors will not infringe our trademarks or that we will have adequate resources to enforce our trademarks. 

Intellectual property rights do not necessarily address all potential threats. 

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations 
and may not adequately protect our business or permit us to maintain our competitive advantage. For example: 

•

Others may be able to make products that are similar to any product candidates we may develop or utilize similar technology 
but that are not covered by the claims of the patents that we license or may own in the future; 

• We, or our license partners or current or future collaborators, might not have been the first to make the inventions covered by 

the issued patent or pending patent application that we license or may own in the future; 

• We, or our license partners or current or future collaborators, might not have been the first to file patent applications covering 

certain of our or their inventions; 

•

Others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing 
our owned or licensed intellectual property rights; 

28

 
 
 
 
 
 
•

•

•

It  is  possible  that  our  pending  licensed  patent  applications  or  those  that  we  may  own  in  the  future  will  not  lead  to  issued 
patents; 

Issued  patents  that  we  hold  rights  to  may  be  held  invalid  or  unenforceable,  including  as  a  result  of  legal  challenges  by  our 
competitors; 

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

• We may not develop additional proprietary technologies that are patentable; 

•

The patents of others may harm our business; and 

• We may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third party may subsequently 

file a patent covering such intellectual property. 

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

Risks Related to Commercialization of Our Product Candidates 

Our commercial success depends upon attaining significant market acceptance of our product candidates, if approved, among physicians, 
healthcare payors, patients and the medical community. 

Even if we obtain regulatory approval for our product candidates, the product may not gain market acceptance among physicians, healthcare 
payors, patients and the medical community, which is critical to commercial success. Market acceptance of any product candidate for which 
we receive approval depends on a number of factors, including: 

•

•

•

•

•

•

•

•

•

•

•

The efficacy and safety as demonstrated in clinical trials; 

The timing of market introduction of the product candidate as well as competitive products; 

The clinical indications for which the product candidate is approved; 

Acceptance by physicians, the medical community and patients of the product candidate as a safe and effective treatment and 
also the willingness of physicians to prescribe a drug based on an active pharmaceutical ingredient (API), that is less familiar to 
them than other drug APIs; 

The convenience of prescribing and initiating patients on the product candidate; 

The potential and perceived advantages of such product candidate over alternative treatments; 

The cost of treatment in relation to alternative treatments, including any similar generic treatments; 

Favorable  pricing  and  the  availability  of  coverage  and  adequate  reimbursement  by  third-party  payors,  such  as  government 
authorities; 

Relative convenience and ease of administration; 

The prevalence and severity of adverse side effects; and 

The effectiveness of sales and marketing efforts. 

If our product candidates are approved but fail to achieve an adequate level of acceptance by physicians, healthcare payors, patients and the 
medical community, we will not be able to generate significant revenue, and we may not become or remain profitable. In addition, even if 
any of our product candidates gain acceptance, the markets for the treatment of patients with our target indications may not be as significant 
as we estimate. 

29

 
 
 
 
 
 
Our organization has no prior sales and marketing experience and resources. 

We have never, as an organization, commercialized a product and there is no guarantee that we will be able to do so successfully. We will 
need to establish a commercial team and hire sales forces in the geographies where we are permitted and intend to market our drugs. We will 
also  need  to  develop  a  marketing  team  and  strategy  in  order  to  successfully  market  and  sell  our  product  candidates,  which  will  require 
significant  time  and  resources  and  the  development  of  our  ability  to  market  and  sell  our  product  and  generate  revenues  from  our  product 
candidates may be delayed or limited. We cannot assure you that our sales efforts will be effective or produce the results we expect. We will 
be  competing  with  other  pharmaceutical  and  biotechnology  companies  to  recruit,  hire,  train  and  retain  marketing  and  sales  personnel. 
Further, we may face difficulties or delays in obtaining and maintaining the required licenses and permits to sell our product candidates in 
individual states and jurisdictions. If the commercialization of any of our product candidates is unsuccessful or perceived as disappointing, 
the  price  of  our  ADSs  or  ordinary  shares  could  decline  significantly  and  the  long-term  success  of  the  product  and  our  company  could  be 
harmed. 

We may also seek to establish collaborations with pharmaceutical companies to maximize the potential of our products in other markets. For 
example, we are conducting a Phase 2b clinical trial to develop eblasakimab as a treatment for atopic dermatitis, and, in the future, we may 
seek  a  global  partner  to  support  Phase  3  clinical  trials  and  potential  commercialization.  We  may  not  be  successful  in  establishing 
development and commercialization collaborations which could adversely affect, and potentially prohibit, our ability to develop our product 
candidates. 

Part of our business strategy is to establish collaborative relationships to commercialize and fund development and approval of certain of 
our product candidates. We may not succeed in establishing and maintaining collaborative relationships, which may significantly limit 
our ability to develop and commercialize products, for which we pursue this commercialization strategy. 

We will need to establish and maintain successful collaborative relationships to obtain sales, marketing and distribution capabilities for the 
product candidates we do not intend to commercialize ourselves. The process of establishing and maintaining collaborative relationships is
difficult, time-consuming and involves significant uncertainty, including: 

• We may have limited control over the decisions of any partners and they may change the priority of any programs in a manner 

that would result in termination or significant delays to a partnered program; 

•

•

•

•

Our  ability  to  generate  future  payments  and  royalties  from  any  partners  will  depend  upon  the  ability  of  a  partner  to  obtain 
regulatory approvals and achieve market acceptance of products developed from our product candidates; 

A partner may fail to properly initiate, maintain or defend our intellectual property rights, where applicable, or a party may use 
our proprietary information in such a way as to invite litigation that could jeopardize or potentially invalidate our proprietary 
information or expose us to potential liability; 

A partner may not devote sufficient capital or resources towards our product candidates; and, 

A partner may not comply with applicable government regulatory requirements necessary to successfully market and sell our 
products. 

If  any  collaborator  fails  to  fulfill  its  responsibilities  in  a  timely  manner,  or  at  all,  any  clinical  development,  manufacturing  or 
commercialization  efforts  pursuant  to  that  collaboration  could  be  delayed  or  terminated,  or  it  may  be  necessary  for  us  to  assume 
responsibility for expenses or activities that would otherwise have been the responsibility of our collaborator. If we are unable to establish 
and maintain collaborative relationships on acceptable terms or to successfully and timely transition terminated collaborative agreements, we 
may  have  to  delay  or  discontinue  further  development  of  one  or  more  of  our  product  candidates,  undertake  development  and 
commercialization activities at our own expense or find alternative sources of capital. 

Attempting to secure additional financing for a product candidate may also lead to the risks discussed under the risk factor titled “We will 
need to obtain substantial amounts of financing for our operations, and if we fail to obtain additional financing, we may be forced to delay, 
reduce or eliminate our product development programs or commercialization efforts” described above. 

30

 
 
 
 
 
 
 
We rely completely on third parties to manufacture our preclinical and clinical drug supplies and we intend to rely on third parties to 
produce commercial supplies of any approved product candidate. 

If we were to experience an unexpected loss of supply of our product candidates for any reason, whether as a result of manufacturing, supply 
or  storage  issues  or  otherwise  (including,  for  example,  any  disruptions  caused  by  the  COVID-19  pandemic),  we  could  experience  delays, 
disruptions,  suspensions  or  terminations  of,  or  be  required  to  restart  or  repeat,  clinical  trials.  We  do  not  currently  have  nor  do  we  plan  to 
acquire the infrastructure or capability internally to manufacture our preclinical and clinical drug supplies and we lack the resources and the 
capability to manufacture any of our product candidates on a clinical or commercial scale. The facilities used by our contract manufacturers 
or other third-party manufacturers to manufacture our product candidates must be approved by the U.S. FDA or other regulators pursuant to 
inspections. While we work closely with our third-party manufacturers on the manufacturing process for our product candidates, including 
quality  audits,  we  generally  do  not  control  the  implementation  of  the  manufacturing  process  of,  and  are  completely  dependent  on,  our 
contract manufacturers or other third-party manufacturers for compliance with cGMP regulatory requirements and for manufacture of both 
active drug substances and finished drug products. 

If  our  contract  manufacturers  or  other  third-party  manufacturers  cannot  successfully  manufacture  material  that  conforms  to  applicable
specifications  and  the  strict  regulatory  requirements  of  the  U.S.  FDA  or  other  regulators,  they  will  not  be  able  to  secure  and/or  maintain 
regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers or other 
third-party manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the U.S. FDA or other regulators 
do not approve these facilities for the manufacture of our product candidates or if they withdraw any such approval in the future, we may 
need to find alternative manufacturing facilities, which could take several years and would significantly impact our ability to develop, obtain 
regulatory approval for or market our product candidates, if approved. 

We  rely  on  our  manufacturers  to  purchase  from  third-party  suppliers  the  materials  necessary  to  produce  our  product  candidates  for  our 
clinical trials. There are a limited number of suppliers of raw materials that we use to manufacture our product candidates and there may be a 
need  to  assess  alternate  suppliers  to  prevent  a  possible  disruption  of  the  manufacture  of  the  materials  necessary  to  produce  our  product 
candidates  for  our  clinical  trials,  and  if  approved,  for  commercial  sale.  We  do  not  have  any  control  over  the  process  or  timing  of  the 
acquisition  of  these  raw  materials  by  our  manufacturers.  Although  we  generally  do  not  begin  a  clinical  trial  unless  we  believe  we  have  a 
sufficient supply of a product candidate to complete the clinical trial, any significant delay in the supply of a product candidate, or the raw 
material components thereof, for an ongoing clinical trial due to the need to replace a contract manufacturer or other third-party manufacturer 
could considerably delay completion of our clinical trials, product testing and potential regulatory approval of our product candidates. If our 
manufacturers or we are unable to purchase these raw materials after regulatory approval has been obtained for our product candidates, the 
commercial launch of our product candidates would be delayed or there would be a shortage in supply, which would impair our ability to 
generate revenue from the sale of our product candidates. 

We  expect  to  continue  to  depend  on  contract  manufacturers  or  other  third-party  manufacturers  for  the  foreseeable  future,  and  our 
requirements for and dependence upon these third-party manufacturers will increase when and if one or more of our product candidates is 
approved  and  commercialized.  We  have  not  entered  into  any  long-term  commercial  supply  agreements  with  our  current  contract 
manufacturers  or  with  any  alternate  contract  manufacturers.  Although  we  intend  to  do  so  prior  to  any  commercial  launch  of  our  product 
candidates, if approved by the U.S. FDA, in order to ensure that we maintain adequate supplies of finished drug product, we may be unable 
to enter into such an agreement or do so on commercially reasonable terms, which could have a material adverse impact upon our business, 
including delaying a product launch or subjecting our commercialization efforts to significant supply risk. Even if we are able to enter into 
long-term agreements with manufacturers for commercial supply on reasonable terms, we may be unable to do so with sufficient time prior to 
the launch of our product candidates, which would expose us to substantial supply risk and potentially jeopardize our launch. 

Manufacturing issues may arise that could increase product and regulatory approval costs or delay commercialization. 

As we scale up manufacturing of our product candidates and conduct required stability testing, product, packaging, equipment and process-
related  issues  may  require  refinement  or  resolution  in  order  to  proceed  with  our  planned  clinical  trials  and  obtain  regulatory  approval  for 
commercial marketing. In the future, we may identify impurities, which could result in increased scrutiny by the regulatory agencies, delays 
in our clinical program and regulatory approval, increases in our operating expenses, or failure to obtain or maintain approval for our product 
candidates. 

31

 
 
 
 
 
 
Guidelines and recommendations published by various organizations can reduce the use of our product candidates. 

Government agencies promulgate regulations and guidelines directly applicable to us and to our product candidates. In addition, professional 
societies, such as practice management groups, private health and science foundations and organizations involved in various diseases from 
time to time may also publish guidelines or recommendations to the healthcare and patient communities. Recommendations of government 
agencies or these other groups or organizations may relate to such matters as usage, dosage, route of administration and use of concomitant 
therapies.  Recommendations  or  guidelines  suggesting  the  reduced  use  of  our  product  candidates  or  the  use  of  competitive  or  alternative 
products as the standard of care to be followed by patients and healthcare providers could result in decreased use of our product candidates. 

We  face  significant  competition  from  other  biopharmaceutical  companies,  and  our  operating  results  will  suffer  if  we  fail  to  compete 
effectively. 

Our  industry  is  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  While  we  believe  that  our  development 
platform,  knowledge,  experience  and  scientific  resources  provide  us  with  competitive  advantages,  we  face  substantial  competition  from 
multinational pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies, universities and other research 
institutions worldwide. For example, there are several therapies currently in clinical development or awaiting regulatory approval for atopic 
dermatitis, including lebrikizumab being developed by Dermira, Inc./Eli Lilly and Company. In addition, dupilumab, developed by Sanofi 
S.A. and Regeneron Pharmaceuticals, Inc., and tralokinumab, developed by Leo Pharma A/S, are approved for the treatment of moderate-to-
severe atopic dermatitis. 

Many of our competitors have significantly greater financial, clinical and human resources. Additionally, small and early-stage companies 
may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large  and  established  companies.  As  a 
result, our competitors may discover, develop, license or commercialize products before or more successfully than we do. Competition may 
increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in 
these  industries.  Our  competitors  may  succeed  in  developing,  acquiring  or  licensing  on  an  exclusive  basis  drug  products  or  drug  delivery 
technologies that are more effective or less costly than our product candidates that we are currently developing or that we may develop. 

We believe that our ability to successfully compete will depend on, among other things: 

•

•

•

•

The  efficacy  and  safety  of  our  product  candidates,  especially  as  compared  to  marketed  products  and  product  candidates  in 
development by third parties; 

The time it takes for our product candidates to complete clinical development and receive marketing approval; 

The ability to commercialize and market any of our product candidates that receive regulatory approval; 

The price of our products; 

• Whether  coverage  and  adequate  levels  of  reimbursement  are  available  from  third-party  payors,  such  as  private  and 

governmental health insurance plans, including Medicare; 

•

•

•

The duration of, and our ability to protect, intellectual property rights related to our product candidates; 

The ability to manufacture on a cost-effective basis and sell commercial quantities of any of our product candidates that receive 
regulatory approval; and 

Acceptance of any of our product candidates that receive regulatory approval by physicians and other healthcare providers. 

If our competitors market products that are more effective, safer or less expensive than our future products, if any, or that reach the market 
sooner  than  our  future  products,  if  any,  we  may  not  achieve  commercial  success.  Because  we  have  limited  research  and  development 
capabilities, it may be difficult for us to stay abreast of the rapid changes in technology. If we fail to stay at the forefront of technological 
change,  we  may  be  unable  to  compete  effectively.  Technological  advances  or  products  developed  by  our  competitors  may  render  our 
technologies or product candidates obsolete, less competitive or not economical. 

32

 
 
 
 
 
 
 
Price controls may adversely affect our future profitability. 

In  certain  countries,  prescription  drug  pricing  and  reimbursement  is  subject  to  governmental  control.  In  those  countries  that  impose  price 
controls, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. 
To obtain reimbursement or pricing approval in some countries, we or our strategic partners may be required to conduct a clinical trial that 
compares the cost-effectiveness of our product candidates to other available therapies. 

Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins 
after  marketing  or  product  licensing  approval  is  granted.  In  certain  markets,  prescription  pharmaceutical  pricing  remains  subject  to 
continuing  governmental  control  even  after  initial  approval  is  granted.  As  a  result,  we  or  our  strategic  partners  might  obtain  marketing 
approval for a product candidate in a particular country, but then be subject to price regulations that delay commercial launch of the product 
candidate, possibly for lengthy time periods, and negatively impact the revenue that we generate from the sale of the product in that country. 
If reimbursement of such product candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, or if 
there is competition from lower priced cross-border sales, our profitability will be negatively affected. 

Legislative or regulatory healthcare reforms may make it more difficult and costly for us to obtain regulatory clearance or approval of 
our product candidates and to produce, market and distribute our products after clearance or approval is obtained. 

From  time  to  time,  legislation  is  drafted  and  introduced  that  could  significantly  change  the  statutory  provisions  governing  the  regulatory 
clearance or approval, manufacture and marketing of regulated products or the reimbursement thereof. In addition, U.S. FDA regulations and 
guidance are often revised or reinterpreted by the U.S. FDA in ways that may significantly affect our business and our products. Any new 
regulations  or  revisions  or  reinterpretations  of  existing  regulations  may  impose  additional  costs  or  lengthen  review  times  of  our  product 
candidates.  We  cannot  determine  what  effect  changes  in  regulations,  statutes,  legal  interpretation  or  policies,  when  and  if  promulgated, 
enacted or adopted may have on our business in the future. Such changes could, among other things, require: 

•

•

•

•

Changes to manufacturing methods; 

Change in clinical trial design, including additional treatment arm (control); 

Recall, replacement or discontinuance of one or more of our products; and 

Additional recordkeeping. 

Each of these would likely entail substantial time and cost and could harm our business and our financial results. 

In addition, in the United States, there have been a number of legislative and regulatory proposals to change the health care system in ways 
that could affect our ability to sell our products profitably. The pharmaceutical industry in the United States, as an example, has been affected 
by the passage of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 
(collectively PPACA) which, among other things, imposed new fees on entities that manufacture or import certain branded prescription drugs 
and expanded pharmaceutical manufacturer obligations to provide discounts and rebates to certain government programs. There have been 
executive,  judicial  and  Congressional  challenges  to  certain  aspects  of  PPACA.  For  example,  on  June  17,  2021  the  U.S.  Supreme  Court 
dismissed a challenge on procedural grounds that argued the PPACA is unconstitutional in its entirety because the “individual mandate” was 
repealed by Congress. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to 
initiate a special enrollment period for purposes of obtaining health insurance coverage through the PPACA marketplace. The executive order 
also  instructs  certain  governmental  agencies  to  review  and  reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare, 
including  among  others,  reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements,  and  policies 
that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance  coverage  through  Medicaid  or  the  PPACA.  On  August  16,  2022, 
President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which, among other things, extends enhanced subsidies for 
individuals purchasing health insurance coverage in PPACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” 
under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a 
new manufacturer discount program. It is possible that the PPACA will be subject to judicial or Congressional challenges in the future. It is 
unclear how such challenges and the healthcare reform measures of the Biden administration will impact the PPACA and our business.

33

 
 
 
 
 
 
 
Other legislative changes have been proposed and adopted in the United States since the PPACA was enacted. For example, in August 2011, 
the Budget Control Act of 2011, among other things, created measures for spending reductions by U.S. Congress. A Joint Select Committee 
on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2012 through 2021, was 
unable  to  reach  required  goals,  thereby  triggering  the  legislation’s  automatic  reduction  to  several  government  programs.  This  includes 
aggregate  reductions  of  Medicare  payments  to  providers  of  up  to  2%  per  fiscal  year,  which  went  into  effect  in  April  2013  and,  due  to 
subsequent legislative amendments to the statute, will remain in effect through 2031 unless additional Congressional action is taken. Under 
current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 4% in the final fiscal year of this sequester. 
In January 2013, the American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to certain providers, 
and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. 

Further,  there  has  been  particular  and  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  drug  pricing 
practices in recent years, particularly with respect to drugs that have been subject to relatively large price increases over relatively short time 
periods. There have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among 
other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform 
government  program  reimbursement  methodologies  for  drugs.  At  the  federal  level,  in  July  2021,  the  Biden  administration  released  an 
executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to 
Biden’s executive order, on September 9, 2021, the U.S. Department of Health and Human Services (HHS) released a Comprehensive Plan 
for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that 
Congress could pursue to advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain 
high-expenditure, single-source drugs and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and 
a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for such drugs and biologics 
under  the  law,  and  (ii)  imposes  rebates  with  respect  to  certain  drugs  and  biologics  covered  under  Medicare  Part  B  or  Medicare  Part  D  to 
penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as opposed to 
regulation, for the initial years. These provisions will take effect progressively starting in fiscal year 2023, although they may be subject to 
legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical 
industry. Further, the Biden administration released an additional executive order on October 14, 2022, directing HHS to submit a report on 
how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for lowering drug costs for Medicare and 
Medicaid beneficiaries. It is unclear whether this executive order or similar policy initiatives will be implemented in the future. At the state
level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  and  biological 
product  pricing,  including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost 
disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. 

In the future, there will likely continue to be proposals relating to the reform of the U.S. healthcare system, some of which could further limit 
coverage and reimbursement of drug products, including our product candidates. 

Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private 
payors. Our results of operations could be adversely affected by PPACA and by other health care reforms that may be enacted or adopted in 
the future. 

It may be difficult for us to profitably sell any future products that may be approved if coverage and reimbursement for these products is 
limited by government authorities and/or third-party payor policies. 

In addition to any healthcare reform measures which may affect reimbursement, market acceptance and sales of our product candidates, if 
approved, will depend on, in part, the extent to which our products, and the procedures which utilize our products, will be covered by third-
party  payors,  such  as  government  health  care  programs,  commercial  insurance  and  managed  care  organizations.  These  third-party  payors 
determine the extent to which new drugs, and the procedures which utilize new drugs, will be covered as a benefit under their plans and the 
level of reimbursement for any covered product and procedures utilizing such products. It is difficult to predict at this time what third-party 
payors will decide with respect to the coverage and reimbursement for our product candidates, and the procedures which utilize our product 
candidates. 

A primary trend in the healthcare industry has been cost containment, including price controls, restrictions on coverage and reimbursement 
and requirements for substitution of generic products and/or biosimilars. Third-party payors decide 

34

 
 
 
 
 
 
which drugs, and procedures using such drugs, they will pay for and establish reimbursement and co-payment levels. Government and other 
third-party payors are increasingly challenging the prices charged for health care products and services, examining the cost effectiveness of 
drugs in addition to their safety and efficacy, and limiting or attempting to limit both coverage and the level of reimbursement for prescription 
drugs and the procedures which utilize prescription drugs. We cannot be sure that coverage will be available for our product candidates, and 
the procedures which utilize our product candidates, if approved, or, if coverage is available, the level of reimbursement. 

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products, and the procedures which 
utilize such products. In the United States, the principal decisions about reimbursement for new medicines, and the procedures which utilize 
new medicines, are typically made by the Centers for Medicare & Medicaid Services (CMS), as CMS decides whether and to what extent a 
new medicine, and procedures which utilize a new medicine, will be covered and reimbursed under Medicare. Private payors may follow 
CMS, but have their own methods and approval processes for determining reimbursement for new medicines, and the procedures that utilize 
new  medicines.  It  is  difficult  to  predict  what  CMS  or  other  payors  will  decide  with  respect  to  reimbursement  for  fundamentally  novel 
products such as ours, as there is no body of established practices and precedents for these new products. 

Reimbursement may impact the demand for, and/or the price of, any product for which we obtain marketing approval. Assuming we obtain 
coverage  for  a  given  product,  or  a  procedure  which  utilizes  a  given  product,  by  a  third-party  payor,  the  resulting  reimbursement  payment 
rates  may  not  be  adequate  or  may  require  co-payments  that  patients  find  unacceptably  high.  Patients  who  are  prescribed  medications  and 
procedures for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part 
of the costs associated with those prescription drugs and procedures. Patients are unlikely to use our products, or agree to procedures utilizing 
our  products,  unless  coverage  is  provided  and  reimbursement  is  adequate  to  cover  all  or  a  significant  portion  of  the  associated  costs. 
Therefore, coverage and adequate reimbursement is critical to new product acceptance. Coverage decisions may depend upon clinical and 
economic  standards  that  disfavor  new  drug  products  when  more  established  or  lower  cost  therapeutic  alternatives  are  already  available  or 
subsequently become available. There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and the 
procedures which utilize newly approved drugs, and coverage may be more limited than the purposes for which such drug is approved by the 
U.S. FDA or comparable foreign regulatory authorities. 

Moreover, eligibility for coverage and reimbursement does not imply that a drug will be paid for in all cases or at a rate that covers our costs, 
including research, development, manufacture, sale and distribution. We expect to experience pricing pressures in connection with the sale of 
any of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations, and 
additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs, medical devices and 
surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the successful 
commercialization of new products. Further, the adoption and implementation of any future governmental cost containment or other health 
reform initiative may result in additional downward pressure on the price that we may receive for any approved product. Reimbursement by a 
third-party payor may depend upon a number of factors including the third-party payor’s determination that use of a product is: 

•

•

•

•

•

A covered benefit under its health plan; 

Safe, effective and medically necessary; 

Appropriate for the specific patient; 

Cost-effective; and 

Neither experimental nor investigational. 

Obtaining coverage and reimbursement approval for a product, or a procedure which utilizes a product, from a government or other third-
party payor is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost effectiveness data 
for the use of our products, and the procedures which utilize our products, to the payor. Further, no uniform policy requirement for coverage 
and  reimbursement  for  drug  products,  and  procedures  which  utilize  drug  products,  exists  among  third-party  payors  in  the  United  States. 
Therefore, coverage and reimbursement for drug products, and the procedures which utilize drug products, can differ significantly from payor 
to payor. As a result, the coverage determination process may require us to provide scientific and clinical support for the use of our products 
to each payor separately, with no assurance that coverage and adequate reimbursement will be 

35

 
 
 
 
applied  consistently  or  obtained  in  the  first  instance.  We  may  not  be  able  to  provide  data  sufficient  to  gain  acceptance  with  respect  to 
coverage  and/or  sufficient  reimbursement  levels.  We  cannot  be  sure  that  coverage  or  adequate  reimbursement  will  be  available  for  our 
product candidates, or the procedures which utilize our product candidates, if approved. Also, we cannot be sure that reimbursement amounts 
will not reduce the demand for, or the price of, our future products. If reimbursement is not available, or is available only to limited levels, 
we may not be able to commercialize our product candidates, or achieve profitably at all, even if approved. 

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information 
privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties. 

Our current and future operations may be directly or indirectly through our relationships with healthcare providers, patients and other persons 
and  entities,  subject  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations  that  may  constrain  the  business  or 
financial arrangements and relationships through which we research, market, sell and distribute our products. In addition, we may be subject 
to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our 
ability to operate include: 

The U.S. Anti-Kickback Statute prohibits, among other things, any person or entity from knowingly and willfully offering, paying, soliciting, 
receiving or providing any remuneration, directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, ordering or 
arranging  for  or  recommending  the  purchase,  lease  or  order  of  any  item  or  service  reimbursable,  in  whole  or  in  part,  under  Medicare, 
Medicaid or other U.S. federal healthcare programs. The U.S. Anti-Kickback Statute has been interpreted to apply to arrangements between 
pharmaceutical manufacturers on the one hand and prescribers, purchasers, and formulary managers, among others, on the other. There are a 
number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. 

The U.S. federal false claims laws, including the False Claims Act (FCA) and civil monetary penalties laws, which prohibit any person or 
entity from, among other things, knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to, or 
approval by, the U.S. federal government or knowingly making, using or causing to be made or used a false record or statement material to a 
false or fraudulent claim to the U.S. federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 
2009, a claim includes “any request or demand” for money or property presented to the U.S. government. In addition, manufacturers can be 
held liable under the FCA even when they do not submit claims directly to government third-party payors if they are deemed to “cause” the 
submission of false or fraudulent claims. The FCA also permits a private individual acting as a “whistleblower” to bring actions on behalf of 
the federal government alleging violations of the FCA and to share in any monetary recovery. FCA liability is potentially significant in the 
healthcare  industry  because  the  statute  provides  for  treble  damages  and  mandatory  penalties  per  false  claim  or  statement.  Government 
enforcement agencies and private whistleblowers have investigated pharmaceutical companies for or asserted liability under the FCA for a 
variety of alleged promotional and marketing activities, such as providing free product to customers with the expectation that the customers 
would bill federal programs for the product; providing consulting fees and other benefits to physicians to induce them to prescribe products; 
engaging in promotion for “off-label” uses; and submitting inflated best price information to the Medicaid Rebate Program. 

HIPAA  prohibits,  among  other  actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare
benefit  program,  including  private  third-party  payors,  knowingly  and  willfully  embezzling  or  stealing  from  a  healthcare  benefit  program, 
willfully  obstructing  a  criminal  investigation  of  a  healthcare  offense,  and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a 
material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare 
benefits, items or services. 

The Physician Payments Sunshine Act, enacted as part of PPACA, imposes, among other things, annual reporting requirements for covered 
manufacturers  for  certain  payments  and  “transfers  of  value”  provided  to  physicians  (defined  to  include  doctors,  dentists,  optometrists, 
podiatrists and chiropractors), other healthcare professionals (such as physicians assistants and nurse practitioners) and teaching hospitals, as 
well as ownership and investment interests held by physicians and their immediate family members. 

HIPAA, as amended by HITECH, and their respective implementing regulations, impose, among other things, specified requirements relating 
to  the  privacy,  security  and  transmission  of  individually  identifiable  health  information  held  by  covered  entities,  which  include  certain 
healthcare  providers,  health  plans  and  healthcare  clearinghouses,  and  their  business  associates,  which  include  individuals  or  entities  that 
perform services for covered entities that involve the creation, use, maintenance or disclosure of, individually identifiable health information, 
and their covered 

36

 
 
 
 
 
 
 
subcontractors. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly 
applicable  to  business  associates,  and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for  damages  or  injunctions  in  U.S. 
federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, 
state  laws  govern  the  privacy  and  security  of  health  information  in  specified  circumstances,  many  of  which  differ  from  each  other  in 
significant ways and may not have the same effect, thus complicating compliance efforts. 

Many U.S. states and other foreign jurisdictions have analogous laws and regulations, such as state anti-kickback and false claims laws, that 
may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party 
payors, including private insurers. In addition, certain states require drug manufacturers to report information related to payments and other 
transfers of value to physicians and other healthcare providers or marketing expenditures and certain states and local jurisdictions require the 
registration of pharmaceutical sales representatives. 

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that
some  of  our  business  activities  could  be  subject  to  challenge  under  one  or  more  of  such  laws.  In  addition,  recent  health  care  reform 
legislation  has  strengthened  these  laws.  For  example,  recent  health  care  reform  legislation,  has  among  other  things,  amended  the  intent 
requirement  of  the  U.S.  Anti-Kickback  Statute  and  criminal  healthcare  fraud  statutes.  A  person  or  entity  no  longer  needs  to  have  actual 
knowledge of this statute or specific intent to violate it in order to have committed a violation. Moreover, recent health care reform legislation 
provides that the government may assert that a claim including items or services resulting from a violation of the U.S. Anti-Kickback Statute 
constitutes a false or fraudulent claim for purposes of the FCA. 

Ensuring that our business arrangements with third parties comply with applicable healthcare laws and regulations will likely be costly. It is 
possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations or 
case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations were found to be in violation of any 
of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative 
penalties,  damages,  fines,  disgorgement,  imprisonment,  possible  exclusion  from  government  funded  healthcare  programs,  contractual 
damages, reputational harm, diminished profits and future earnings, additional reporting obligations and oversight if we become subject to a 
corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations, 
any of which could substantially disrupt our operations. If the physicians or other providers or entities with whom we expect to do business 
are  found  not  to  be  in  compliance  with  applicable  laws,  they  may  be  subject  to  criminal,  civil  or  administrative  sanctions,  including 
exclusions from government-funded healthcare programs. 

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance 
with such laws can subject us to criminal and/or civil liability and harm our business. 

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 
201,  the  U.S.  Travel  Act,  the  USA  PATRIOT  Act,  and  possibly  other  state  and  national  anti-bribery  and  anti-money  laundering  laws  in 
countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, 
third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering, or providing, directly or indirectly, 
improper payments or benefits to recipients in the public or private sector. We engage third-party investigators, CROs, and other consultants 
to  design  and  perform  preclinical  studies  of  our  product  candidates,  and  will  do  the  same  for  any  clinical  trials.  Also,  once  a  product 
candidate has been approved and commercialized, we may engage third-party intermediaries to promote and sell our products abroad and/or 
to  obtain  necessary  permits,  licenses,  and  other  regulatory  approvals.  We  or  our  third-party  intermediaries  may  have  direct  or  indirect 
interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or 
other  illegal  activities  of  these  third-party  intermediaries,  our  employees,  representatives,  contractors,  collaborators,  partners,  and  agents, 
even if we do not explicitly authorize or have actual knowledge of such activities. 

Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, 
settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or 
injunctions,  suspension  and/or  debarment  from  contracting  with  certain  persons,  the  loss  of  export  privileges,  reputational  harm,  adverse 
media  coverage,  and  other  collateral  consequences.  If  any  subpoenas,  investigations,  or  other  enforcement  actions  are  launched,  or 
governmental or other sanctions are 

37

 
 
 
 
 
 
imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could 
be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention 
and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even 
cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens. 

The incidence and prevalence for target patient populations of our product candidates are based on estimates and third-party sources. If 
the market opportunities for our product candidates are smaller than we estimate or if any approval that we obtain is based on a narrower 
definition of the patient population, our revenue and ability to achieve profitability might be materially and adversely affected. 

Periodically, we make estimates regarding the incidence and prevalence of target patient populations for particular diseases based on various 
third-party sources and internally generated analysis and use such estimates in making decisions regarding our drug development strategy, 
including acquiring or in-licensing product candidates and determining indications on which to focus in preclinical or clinical trials. 

These estimates may be inaccurate or based on imprecise data. For example, the total addressable market opportunity will depend on, among 
other things, acceptance of our drugs by the medical community and patient access, drug pricing and reimbursement. The number of patients 
in the addressable markets may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our drugs, or 
new  patients  may  become  increasingly  difficult  to  identify  or  gain  access  to,  all  of  which  may  significantly  harm  our  business,  financial
condition, results of operations and prospects. 

Risks Related to our ADSs 

The price of our ADSs has been, and may continue to be, volatile and may fluctuate due to factors beyond our control. 

The trading market for publicly traded emerging biopharmaceutical and drug discovery and development companies has been highly volatile 
and is likely to remain highly volatile in the future. The stock market in general and the market for biopharmaceutical and drug discovery and 
development  companies  in  particular,  has  experienced  extreme  volatility  that  has  often  been  unrelated  to  the  operating  performance  of 
particular companies. The COVID-19 pandemic and the ongoing conflict between Ukraine and Russia, for example, have negatively affected 
the  stock  market  and  investor  sentiment  and  this  has  resulted  in  significant  volatility.  The  market  price  of  our  ADSs  may  fluctuate 
significantly due to a variety of factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

Positive or negative results from, or delays in, testing and clinical trials by us, our collaborators or our competitors; 

Technological innovations or commercial product introductions by us or competitors; 

Changes in government regulations; 

Changes in the structure of healthcare payment systems; 

Developments concerning proprietary rights, including patents and litigation matters; 

Public concern relating to the commercial value or safety of our product candidates; 

Financing, collaborations or other corporate transactions; 

Publication of research reports or comments by securities or industry analysts; 

General market conditions in the pharmaceutical industry or in the economy as a whole; 

The loss of any of our key scientific or senior management personnel; 

Sales  of  our  ADSs  or  ordinary  shares  by  us,  our  senior  management  and  board  members  or  holders  of  our  ADSs  or  our 
ordinary shares in the future; or 

Other events and factors, many of which are beyond our control. 

These and other market and industry factors may cause the market price and demand for our ADSs to fluctuate substantially, regardless of 
our actual operating performance, which may limit or prevent investors from readily selling their ADSs and may otherwise negatively affect 
the liquidity of our ADSs. In addition, the stock market in general, and 

38

 
 
 
 
 
 
 
biopharmaceutical  companies  in  particular,  have  experienced  extreme  price  and  volume  fluctuations  that  have  often  been  unrelated  or 
disproportionate to the operating performance of these companies. In the past, when the market price of a security has been volatile, holders 
of that security have sometimes instituted securities class action litigation against the issuer. If any of the holders of our ADSs were to bring 
such  a  lawsuit  against  us,  we  could  incur  substantial  costs  defending  the  lawsuit  and  the  attention  of  our  senior  management  would  be 
diverted from the operation of our business. Any adverse determination in litigation could also subject us to significant liabilities. 

If we are unable to regain compliance with the listing requirements of the Nasdaq Capital Market, our ADSs may remain delisted from 
the Nasdaq Capital Market which could have a material adverse effect on our financial condition and could make it more difficult for you 
to sell your shares.

Our ADSs were previously listed on the Nasdaq Global Market, and we were therefore subject to its continued listing requirements, including 
requirements  with  respect  to  the  market  value  of  publicly  held  ADSs,  market  value  of  listed  ADSs,  minimum  bid  price  per  ADS,  and 
minimum shareholders’ equity, among others, and requirements relating to board and committee independence. 

On March 28, 2022, we received a notice from Nasdaq that we were not in compliance with the $1.00 minimum bid price requirement for 
continued listing on the Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5450(a)(1) (the Minimum Bid Price Requirement). The 
notice  indicated  that,  consistent  with  Nasdaq  Listing  Rule  5810(c)(3)(A),  we  had  180  days,  or  until  September  26,  2022,  to  regain 
compliance with the Minimum Bid Price Requirement by having the minimum bid price of our ADSs meet or exceed $1.00 per ADS for at 
least ten consecutive business days. The notice had no immediate effect on the listing of our ADSs, and our ADSs continued to trade on the 
Nasdaq Global Market under the symbol “ASLN” at such time.

We did not expect to regain compliance by September 26, 2022 and on September 14, 2022, we applied to transfer our listing to the Nasdaq 
Capital Market and are required to meet the continued listing requirement for market value of publicly held ADSs and all other initial listing 
standards  for  the  Nasdaq  Capital  Market,  except  for  the  Minimum  Bid  Price  Requirement.  Upon  transfer  to  the  Nasdaq  Capital  Market, 
which transfer became effective on September 29, 2022, we were afforded an additional 180 calendar day period, or until March 27, 2023, to 
regain compliance with the Minimum Bid Price Requirement. In addition, we notified Nasdaq of our intent to cure the deficiency during the 
second compliance period. 

In  order  to  regain  compliance  with  the  Minimum  Bid  Price  Requirement,  we  effected  a  change  to  the  ratio  of  our  ADSs  to  our  ordinary 
shares from one ADS representing five ordinary shares to one ADS representing twenty-five ordinary shares on March 13, 2023. As a result, 
the bid price of our ADSs increased proportionally and we expect to regain compliance with the Minimum Bid Price Requirement by March 
27, 2023. If we do not regain compliance with the Minimum Bid Price Requirement by March 27, 2023, our ADSs will become subject to 
delisting.  In  the  event  we  receive  notice  that  our  ADSs  are  being  delisted,  the  Nasdaq  listing  rules  permit  us  to  appeal  a  delisting 
determination to a hearings panel.

There can be no assurance, however, that we will be able to regain compliance with the Minimum Bid Price Requirement, and even if we do, 
there can be no assurance that we will be able to maintain compliance with the continued listing requirements for the Nasdaq Capital Market 
or that our ADSs will not be delisted in the future. In addition, we may be unable to meet other applicable listing requirements of the Nasdaq 
Capital Market, including maintaining minimum levels of shareholders’ equity or market values of our ADSs in which case, our ADSs could 
be delisted notwithstanding our ability to demonstrate compliance with the Minimum Bid Price Requirement.

Delisting from the Nasdaq Capital Market may adversely affect our ability to raise additional financing through the public or private sale of 
equity securities, may significantly affect the ability of investors to trade our securities and may negatively affect the value and liquidity of 
our  ADSs.  Delisting  also  could  have  other  negative  results,  including  the  potential  loss  of  employee  confidence,  the  loss  of  institutional 
investors or interest in business development opportunities.

39

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because 
we are incorporated under Cayman Islands law, we conduct substantially all of our operations and substantially all of our directors and 
executive officers reside outside of the United States. 

We  are  an  exempted  company  incorporated  under  the  laws  of  the  Cayman  Islands.  Our  corporate  affairs  are  governed  by  our  Eleventh 
Amended and Restated Memorandum and Articles of Association (Articles), the Companies Act (as amended) of the Cayman Islands (the 
Companies  Act),  and  the  common  law  of  the  Cayman  Islands.  The  rights  of  shareholders  to  take  action  against  the  directors,  actions  by 
minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common 
law of the Cayman Islands. 

The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as 
from the common law of England and Wales, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the 
Cayman  Islands.  Similarly,  the  rights  of  our  shareholders  and  the  fiduciary  duties  of  our  directors  under  Cayman  Islands  law  are  not  as 
clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman 
Islands  has  a  less  developed  body  of  securities  laws  than  the  United  States,  and  some  U.S.  states,  such  as  Delaware,  have  more  fully 
developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies do not have 
standing to sue before the federal courts of the United States. 

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records 
or to obtain copies of lists of shareholders of these companies. Although our shareholders are permitted by our Articles to request access to 
our books and records, our directors have discretion under our Articles to determine whether or not, and under what conditions, our corporate 
records  may  be  inspected  by  our  shareholders,  but  are  not  obliged  to  make  them  available  to  our  shareholders.  This  may  make  it  more 
difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other 
shareholders in connection with a proxy contest. 

Certain  corporate  governance  practices  in  the  Cayman  Islands,  which  is  our  home  country,  differ  significantly  from  requirements  for 
companies incorporated in other jurisdictions such as the United States. To the extent we choose to follow home country practice with respect 
to  corporate  governance  matters,  our  shareholders  may  be  afforded  less  protection  than  they  otherwise  would  under  rules  and  regulations 
applicable to U.S. domestic issuers. 

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by 
management,  members  of  the  board  of  directors  or  controlling  shareholders  than  they  would  as  public  shareholders  of  a  company 
incorporated  in  the  United  States.  For  a  discussion  of  significant  differences  between  the  provisions  of  the  Companies  Act  and  the  laws
applicable to companies incorporated in the United States and their shareholders, see “Memorandum and Articles of Association–Material 
Differences in Corporate Law”. 

Future sales, or the possibility of future sales, of a substantial number of our ADSs or ordinary shares could adversely affect the price of 
our ADSs. 

Future sales of a substantial number of our ADSs or ordinary shares, or the perception that such sales will occur, could cause a decline in the 
market price of our ADSs or ordinary shares. If any of our large shareholders or members of our management team sell substantial amounts 
of our securities in the public markets, or the market perceives that such sales may occur, the market price of our ADSs and our ability to 
raise capital through an issue of equity securities in the future could be adversely affected. 

We may sell additional equity or debt securities or enter into other financing arrangements to fund our operations, which may result in 
dilution to our shareholders and holders of our ADSs and impose restrictions on our business. 

In order to raise additional funds to support our operations, we may sell additional equity or debt securities, which could adversely impact our 
existing shareholders and new investors, as well as our business. The sale of additional equity or debt securities, or a combination of both, 
would result in the issuance of additional shares capital and dilution to our shareholders and holders of our ADSs. Please refer to the section 
titled “Item 18. Financial Statements” for more information on the issuance of ADSs.
For  example,  there  are  a  large  number  of  ordinary  shares  or  ADSs  underlying  the  pre-funded  warrants  and  warrants  issued  in  our  recent 
private  placement  offering  in  February  2023.  As  of  February  28,  2023,  the  outstanding  pre-funded  warrants  and  warrants,  assuming  full 
exercise, would be exercisable into an aggregate of 328,947,245 of our ordinary 

40

shares (or the equivalent of 65,789,449 ADSs) which would result in dilution to our shareholders and holders of our ADSs. Further, the sale 
of the ADSs underlying such pre-funded warrants and warrants may adversely affect the market price of our ADSs. 

The  incurrence  of  indebtedness  would  result  in  increased  fixed  payment  obligations  and  could  also  result  in  certain  restrictive  covenants, 
such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and 
other operating restrictions that could adversely impact our ability to conduct our business. In the event that we enter into collaborations or
licensing arrangements to raise capital, we may be required to accept unfavorable terms, including relinquishing or licensing to a third party 
on unfavorable terms our rights to technologies or product candidates that we otherwise would seek to develop or commercialize ourselves or 
potentially reserve for future potential arrangements when we might be able to achieve more favorable terms. 

Because we do not anticipate paying any cash dividends on our ADSs or ordinary shares in the foreseeable future, capital appreciation, if 
any, will be your sole source of potential gains and you may never receive a return on your investment. 

We have not paid cash dividends in the past on our ordinary shares. We intend to retain earnings, if any, for use in our business and do not 
anticipate paying any cash dividends in the foreseeable future. In addition, we are not permitted to dispose of our assets pursuant to the terms 
of the K2HV Facility without the prior consent of K2HV except for Permitted Transfers (as defined in the K2HV loan agreement). Further 
the K2HV loan agreement contains terms prohibiting dividends that may be declared or paid on our ADSs or ordinary shares. As a result, 
capital appreciation, if any, on our ADSs or ordinary shares will be your sole source of potential gains for the foreseeable future, and you will 
suffer a loss on your investment if you are unable to sell your ADSs or the underlying ordinary shares at or above the price you pay for our 
ADSs or ordinary shares. Investors seeking cash dividends should not purchase our ADSs. 

Purchasers of our ADSs may not have the same voting rights as the holders of our ordinary shares and may not receive voting materials 
in time to be able to exercise their right to vote. 

As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying ordinary shares in accordance with 
the provisions of the deposit agreement for our ADSs (the deposit agreement). Under the deposit agreement, you must vote by giving voting 
instructions  to  the  depositary.  Upon  receipt  of  your  voting  instructions,  the  depositary  will  try  to  vote  the  underlying  ordinary  shares  in 
accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless 
you  withdraw  the  shares.  When  a  general  meeting  is  convened,  you  may  not  receive  sufficient  advance  notice  to  withdraw  the  shares 
underlying  your  ADSs  to  allow  you  to  vote  with  respect  to  any  specific  matter.  After  we  notify  the  depositary  of  the  agenda  for  the 
shareholders’ meeting, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you once they 
are available. We have agreed to give the depositary at least 35 days’ prior notice of shareholder meetings. Nevertheless, we cannot assure 
you  that  you  will  receive  the  voting  materials  in  time  to  ensure  that  you  can  instruct  the  depositary  to  vote  your  shares.  In  addition,  the 
depositary  and  its  agents  are  not  responsible  for  failing  to  carry  out  voting  instructions  or  for  their  manner  of  carrying  out  your  voting 
instructions. This means that you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying 
your ADSs are not voted as you requested. 

41

Except in limited circumstances, the depositary for our ADSs will give us a discretionary proxy to vote our ordinary shares underlying 
your ADSs if you do not vote at shareholders’ meetings, which could adversely affect your interests. 

Under the deposit agreement, to the extent we have provided the depositary with at least 35 days’ notice of a proposed meeting, if voting 
instructions are not timely received by the depositary from you, you shall be deemed to have instructed the depositary to give a discretionary 
proxy to a person designated by us to vote the shares represented by your ADSs as desired. However, no such instruction shall be deemed 
given and no discretionary proxy shall be given (a) if we inform the depositary in writing that (i) we do not wish such proxy to be given, (ii) 
substantial  opposition  exists  with  respect  to  any  agenda  item  for  which  the  proxy  would  be  given  or  (iii)  the  agenda  item  in  question,  if 
approved, would materially or adversely affect the rights of holders of shares and (b) unless we have provided the depositary with an opinion 
of our counsel to the effect that (a) the granting of such discretionary proxy does not subject the depositary to any reporting obligations in the 
Cayman Islands, (b) the granting of such proxy will not result in a violation of Cayman Islands laws, rules, regulations or permits, (c) the 
voting  arrangement  and  deemed  instruction  will  be  given  effect  under  Cayman  Islands  laws,  rules,  regulations  and  permits,  and  (d)  the 
granting of such proxy will not under any circumstances result in the depositary being treated as the beneficial owner of ADSs under Cayman 
Islands laws, rules, regulations or permits. 

The effect of this discretionary proxy is that, if you fail to give voting instructions to the depositary as to how to vote the ordinary shares 
underlying your ADSs at any particular shareholders’ meeting, you cannot prevent our ordinary shares underlying your ADSs from being 
voted at that meeting, absent the situations described above, and it may make it more difficult for shareholders to influence our management. 
Holders of our ordinary shares are not subject to this discretionary proxy. 

Purchasers of our ADSs may not receive distributions on our ordinary shares in the form of ADSs or any value for them if it is illegal or 
impractical to make them available to holders of ADSs. 

The  depositary  for  our  ADSs  has  agreed  to  pay  to  purchasers  of  our  ADSs  the  cash  dividends  or  other  distributions  it  or  the  custodian 
receives on our ordinary shares or other deposited securities after deducting its fees and expenses and certain taxes. Purchasers of our ADSs 
will receive these distributions in proportion to the number of our ordinary shares their ADSs represent. However, in accordance with the 
limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. We have 
no obligation to take any other action to permit the distribution of our ADSs, ordinary shares, rights or anything else to holders of our ADSs. 
This means that purchasers of our ADSs may not receive the distributions we make on our ordinary shares or any value from them if it is 
unlawful or impractical to make them available to ADS holders. These restrictions may have a negative impact on the market value of our 
ADSs. 

Purchasers of our ADSs may be subject to limitations on transfer of their ADSs. 

ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time 
when  it  deems  expedient  in  connection  with  the  performance  of  its  duties.  In  addition,  the  depositary  may  refuse  to  deliver,  transfer  or 
register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it 
advisable  to  do  so  because  of  any  requirement  of  law  or  of  any  government  or  governmental  body,  or  under  any  provision  of  the  deposit 
agreement, or for any other reason in accordance with the terms of the deposit agreement. The rights of our shareholders may differ from the 
rights typically offered to shareholders of a U.S. corporation. 

Our corporate affairs are governed by our Articles and by the laws governing Cayman Islands corporations and companies engaging in drug 
development, marketing and sales businesses, as well as by the common law of the Cayman Islands. Certain rights and responsibilities of our 
shareholders,  ADS  holders  and  members  of  our  board  of  directors  under  Cayman  law  are  different  from  those  that  apply  to  a  Delaware 
corporation. For example, Directors of Cayman Islands exempted companies are required to observe certain fiduciary duties. These duties are 
owed  to  the  Cayman  Islands  company  and  include  the  duty  to  act  in  the  best  interests  of  the  company  and  the  shareholders  as  a  whole. 
However, the fiduciary duties of a director of a Cayman Islands exempted company may not be the same as the fiduciary duties of a director 
of  a  U.S.  corporation.  In  addition,  controlling  shareholders  of  U.S.  corporations  owe  fiduciary  duties  to  minority  shareholders,  while 
shareholders (including controlling shareholders) of Cayman Islands companies owe no fiduciary duties either to the company or to other 
shareholders. 

42

Further, the rights of our shareholders to bring shareholders’ suits against us or our board of directors under Cayman Islands law are much 
more limited than those of shareholders of a U.S. corporation. For example, under Cayman Islands law, a shareholder who wishes to bring a 
claim against a director would generally need to obtain permission from the courts to bring a derivative action, in the name of the company, 
against the director. This is because the director of a Cayman Islands exempted company owes duties to the company and not to individual 
shareholders. As a result, our shareholders may have more difficulty protecting their rights in connection with actions taken by our directors 
than they would as shareholders of a U.S. corporation. In addition, minority shareholders in a Cayman Islands exempted company have more 
limited rights than minority shareholders in a U.S. corporation in relation to mergers and similar transactions that the company may carry out. 
For example, if a merger under the Companies Act involving a Cayman Islands exempted company is approved by the requisite majority of 
shareholders, a dissenting minority shareholder would have the right to be paid the fair value of their shares (which, if not agreed between the 
parties, will be determined by the Cayman Islands court) if they follow the required procedures, subject to certain exceptions. Such dissenter 
rights differ substantially from the appraisal rights, which would ordinarily be available to dissenting shareholders of Delaware corporations. 
Further, if a takeover offer is made to the shareholders of a Cayman Islands exempted company and accepted by holders of 90% of the shares 
affected, the offeror may require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be 
made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there 
is evidence of fraud, bad faith or collusion. A minority shareholder in this scenario would have no rights comparable to the appraisal rights 
which  would  generally  be  available  to  a  dissenting  shareholder  of  a  U.S.  corporation  in  similar  circumstances.  For  a  description  of  the 
principal  differences  between  the  provisions  of  Cayman  law  applicable  to  us  and  the  U.S.  Delaware  General  Corporate  Law  relating  to 
shareholders’ rights and protections, see “Memorandum and Articles of Association–Material Differences in Corporate Law”.  

We qualify as a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act reporting 
obligations that permit less detailed and less frequent reporting than that of a U.S. domestic public company. 

We report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer
under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, 
including  (i)  the  sections  of  the  Exchange  Act  regulating  the  solicitation  of  proxies,  consents  or  authorizations  in  respect  of  a  security 
registered under the Exchange Act; (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and 
trading activities and liability for insiders who profit from trades made in a short period of time; and (iii) the rules under the Exchange Act 
requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current 
reports on Form 8-K upon the occurrence of specified significant events. In addition, our officers, directors and principal shareholders are 
exempt  from  the  reporting  and  “short-swing”  profit  recovery  provisions  of  Section  16  of  the  Exchange  Act  and  the  rules  thereunder. 
Therefore,  our  shareholders  may  not  know  on  a  timely  basis  when  our  officers,  directors  and  principal  shareholders  purchase  or  sell  our 
ordinary shares or ADSs. In addition, foreign private issuers are not required to file their annual report on Form 20-F until the date that is 
four months after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on 
Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers also are exempt from Regulation Fair Disclosure, aimed at 
preventing  issuers  from  making  selective  disclosures  of  material  information.  As  a  result  of  the  above,  you  may  not  have  the  same 
protections afforded to shareholders of companies that are not foreign private issuers. 

As  a  foreign  private  issuer,  we  are  permitted  to  adopt  certain  home  country  practices  in  relation  to  corporate  governance  matters  that 
differ  significantly  from  Nasdaq  Stock  Market  LLC  (Nasdaq)  corporate  governance  listing  standards.  These  practices  may  afford  less 
protection to shareholders than they would enjoy if we complied fully with corporate governance listing standards. 

As  a  foreign  private  issuer,  we  are  permitted  to  take  advantage  of  certain  provisions  in  the  Nasdaq  listing  rules  that  allow  us  to  follow 
Cayman Islands law for certain governance matters. Certain corporate governance practices in the Cayman Islands may differ significantly 
from  corporate  governance  listing  standards.  We  intend  to  continue  to  follow  Cayman  Islands  corporate  governance  practices  in  lieu  of 
certain corporate governance requirements of Nasdaq. Therefore, our shareholders may be afforded less protection than they otherwise would 
have under corporate governance listing standards applicable to U.S. domestic issuers. 

43

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses. 

As  discussed  above,  we  are  a  foreign  private  issuer,  and  therefore,  we  are  not  required  to  comply  with  all  of  the  periodic  disclosure  and 
current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business 
day of an issuer’s most recently completed second fiscal quarter. We would lose our foreign private issuer status if, for example, more than 
50%  of  our  ordinary  shares  are  directly  or  indirectly  held  by  residents  of  the  United  States  and  we  fail  to  meet  additional  requirements 
necessary to maintain our foreign private issuer status. If we lose our foreign private issuer status on this date, we will be required to file with 
the SEC periodic reports and registration statements on U.S. domestic issuer forms, which are more detailed and extensive than the forms 
available  to  a  foreign  private  issuer.  We  will  also  have  to  mandatorily  comply  with  U.S.  federal  proxy  requirements,  and  our  officers, 
directors  and  principal  shareholders  will  become  subject  to  the  short-swing  profit  disclosure  and  recovery  provisions  of  Section  16  of  the 
Exchange  Act.  In  addition,  we  will  lose  our  ability  to  rely  upon  exemptions  from  certain  corporate  governance  requirements  under  the 
Nasdaq listing rules. As a U.S. listed public company that is not a foreign private issuer, we will incur significant additional legal, accounting 
and  other  expenses  that  we  will  not  incur  as  a  foreign  private  issuer,  and  accounting,  reporting  and  other  expenses  in  order  to  maintain  a 
listing  on  a  U.S.  securities  exchange.  These  rules  and  regulations  could  also  make  it  more  difficult  for  us  to  attract  and  retain  qualified 
members of our board of directors and more expensive to procure director and officer liability insurance. 

Our U.S. ADS Holders may suffer adverse tax consequences if we are characterized as a passive foreign investment company. 

Generally, if for any taxable year (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average quarterly value of 
our  assets  are  held  for  the  production  of,  or  produce,  passive  income,  we  would  be  characterized  as  a  PFIC  for  U.S.  federal  income  tax 
purposes. For purposes of the above calculations, a non-U.S. corporation that directly or indirectly owns at least 25% by value of the shares 
of  another  corporation  is  treated  as  if  it  held  its  proportionate  share  of  the  assets  of  the  other  corporation  and  received  directly  its 
proportionate share of the income of the other corporation. Passive income generally includes dividends, interest, rents, royalties and capital 
gains. Based on estimates of our gross income and gross assets (including tangible assets and intangible assets based on the market value of 
our ordinary shares), and the nature of our business, we believe that we were a PFIC for the taxable year ended December 31, 2022. There 
can  be  no  assurance  regarding  our  PFIC  status  for  any  taxable  year.  If  we  are  characterized  as  a  PFIC,  our  U.S.  shareholders  may  suffer 
adverse tax consequences, including having gains realized on the sale of our ordinary shares treated as ordinary income, rather than as capital 
gain,  the  loss  of  the  preferential  rate  applicable  to  dividends  received  on  our  ordinary  shares  by  individuals  who  are  “U.S.  Holders”,  and 
having interest charges apply to distributions by us and the proceeds of share sales and having to comply with certain reporting requirements. 
As  used  in  this  discussion,  the  term  U.S.  Holder  has  the  meaning  given  it  in  the  second  paragraph  of  the  discussion  under  “Item  10.E 
Taxation—Material U.S. Federal Income Tax Considerations for U.S. Holders.” Certain elections exist that may alleviate some of the adverse 
consequences of PFIC status and would result in an alternative treatment (such as mark-to-market treatment) of our ordinary shares; however, 
while  we  will  consider  providing  the  information  necessary  for  U.S.  Holders  to  make  qualified  electing  fund  (QEF)  elections  if  we  are 
classified as a PFIC, we provide no assurance that we will do so, in which case such QEF elections would not be available for a U.S. Holder.

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

If a United States person is treated as owning (directly, indirectly, or constructively) at least 10% of the value or voting power of our ordinary 
shares (as a result of such person’s ownership of ADSs), such person may be treated as a “United States shareholder” with respect to each 
“controlled foreign corporation” in our group. Because our group includes one or more U.S. subsidiaries, we expect that certain of our non-
U.S.  subsidiaries  will  be  treated  as  controlled  foreign  corporations  (regardless  of  whether  or  not  we  are  treated  as  a  controlled  foreign 
corporation).  A  United  States  shareholder  of  a  controlled  foreign  corporation  may  be  required  to  report  annually  and  include  in  its  U.S. 
taxable  income  its  pro  rata  share  of  “Subpart  F  income,”  “global  intangible  low-taxed  income,”  and  investments  in  U.S.  property  by 
controlled  foreign  corporations,  regardless  of  whether  we  make  any  distributions.  An  individual  that  is  a  United  States  shareholder  with 
respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed 
to  a  United  States  shareholder  that  is  a  U.S.  corporation.  Failure  to  comply  with  these  reporting  obligations  may  subject  a  United  States 
shareholder  to  significant  monetary  penalties  and  may  prevent  the  statute  of  limitations  with  respect  to  such  shareholder’s  U.S.  federal 
income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist investors in
determining whether 

44

any  of  our  non-U.S.  subsidiaries  is  treated  as  a  controlled  foreign  corporation  or  whether  any  investor  is  treated  as  a  United  States 
shareholder  with  respect  to  any  such  controlled  foreign  corporation  or  furnish  to  any  United  States  shareholders  information  that  may  be 
necessary  to  comply  with  the  aforementioned  reporting  and  tax  paying  obligations.  A  United  States  investor  should  consult  its  advisors 
regarding the potential application of these rules to an investment in our ADSs.

General Risk Factors 

We  have  incurred  and  will  incur  increased  costs  as  a  result  of  operating  as  a  public  company  in  the  United  States,  and  our  senior 
management will be required to devote substantial time to new compliance initiatives and corporate governance practices. 

Our ADSs began trading on The Nasdaq Global Market on May 4, 2018, under the trading symbol “ASLN” and on September 29, 2022, we 
transferred to The Nasdaq Capital Market and continued trading under the same trading symbol “ASLN.” As a U.S. public company, we have 
incurred significant legal, accounting and other expenses that we did not incur previously, and we will incur additional expenses after we no 
longer qualify as an EGC. We expect that we will no longer qualify as an EGC on December 31, 2023. The Sarbanes-Oxley Act of 2002, the 
Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of Nasdaq, and other applicable securities rules and 
regulations impose various requirements on non-U.S. reporting public companies, including the establishment and maintenance of effective 
disclosure  and  financial  controls  and  corporate  governance  practices.  Our  senior  management  and  other  personnel  will  need  to  devote  a 
substantial  amount  of  time  to  these  compliance  initiatives.  Moreover,  these  rules  and  regulations  will  increase  our  legal  and  financial 
compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations 
may make it more difficult and more expensive for us to obtain director and officer liability insurance, which in turn could make it more 
difficult for us to attract and retain qualified senior management personnel or members for our board of directors. 

However,  these  rules  and  regulations  are  often  subject  to  varying  interpretations,  in  many  cases  due  to  their  lack  of  specificity,  and,  as  a 
result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result 
in  continuing  uncertainty  regarding  compliance  matters  and  higher  costs  necessitated  by  ongoing  revisions  to  disclosure  and  governance 
practices. 

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 (Section 404), we will be required to furnish a report by our senior management 
on our internal control over financial reporting and an attestation report on internal control over financial reporting issued by our independent 
registered  public  accounting  firm.  However,  while  we  remain  an  EGC  we  will  not  be  required  to  include  an  attestation  report  on  internal 
control over financial reporting issued by our independent registered public accounting firm. We expect that we will no longer qualify as an 
EGC  on  December  31,  2023.  To  achieve  compliance  with  Section  404  within  the  prescribed  period,  we  will  be  engaged  in  a  process  to 
document  and  evaluate  our  internal  control  over  financial  reporting,  which  is  both  costly  and  challenging.  In  this  regard,  we  will  need  to 
continue  to  dedicate  internal  resources,  potentially  engage  outside  consultants,  adopt  a  detailed  work  plan  to  assess  and  document  the 
adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that 
controls are functioning as documented, and implement a continuous reporting and improvement process for internal control over financial 
reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal 
control over financial reporting is effective as required by Section 404. If we identify one or more material weaknesses, it could result in an 
adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements. 

45

If  we  fail  to  maintain  an  effective  system  of  internal  controls  over  financial  reporting,  we  may  not  be  able  to  accurately  report  our 
financial  results  or  prevent  fraud.  As  a  result,  shareholders  could  lose  confidence  in  our  financial  and  other  public  reporting,  which 
would harm our business and the trading price of our ADSs. 

Effective  internal  controls  over  financial  reporting  are  necessary  for  us  to  provide  reliable  financial  reports  and,  together  with  adequate 
disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties 
encountered  in  their  implementation  could  cause  us  to  fail  to  meet  our  reporting  obligations.  In  addition,  any  testing  by  us  conducted  in 
connection with Section 404, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our 
internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to 
our financial statements or identify other areas for further attention or improvement. Inadequate internal controls could also cause investors to 
lose confidence in our reported financial information, which could have a negative effect on the trading price of our ADSs. 

Management is required to assess the effectiveness of our internal controls annually. However, for as long as we are an EGC, our independent 
registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting pursuant to 
Section 404. We expect that we will no longer qualify as an EGC on December 31, 2023. An independent assessment of the effectiveness of 
our  internal  controls  could  detect  problems  that  our  management’s  assessment  might  not.  Undetected  material  weaknesses  in  our  internal 
controls could lead to financial statement restatements requiring us to incur the expense of remediation and could also result in an adverse 
reaction in the financial markets due to a loss of confidence in the reliability of our financial statements. 

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of 
our ADSs and our trading volume could decline. 

The  trading  market  for  our  ADSs  depends  in  part  on  the  research  and  reports  that  securities  or  industry  analysts  publish  about  us  or  our 
business. If no or too few securities or industry analysts provide coverage or if one or more of the analysts who cover us downgrade our 
ADSs or publish inaccurate or unfavorable research about our business, the price of our ADSs would likely decline. If one or more of these 
analysts cease coverage of us or fail to publish reports on us regularly, demand for our ADSs could decrease, which might cause the price of 
our ADSs and trading volume to decline.

George Town, Grand Cayman KY1-9008 Cayman Islands. Our agent for service of process in the United States is Cogency Global Inc. 10 
East 40th Street 10th Floor, New York, New York 10016, and the telephone number is +1 212 947 7200. The SEC maintains an internet site 
that  contains  reports,  proxy  and  information  statements,  and  other  information  regarding  issuers  that  file  electronically  with  the  SEC  at 
http://www.sec.gov.  We  also  maintain  a  corporate  website  at  www.aslanpharma.com.  Information  contained  in,  or  that  can  be  accessed 
through, our website is not a part of, and shall not be incorporated by reference into, this document. We have included our website address in 
this document solely as an inactive textual reference.

Under ASLAN Pharmaceuticals Limited, there are several legal entities as our fully owned subsidiaries and investment in associates. Our 
fully  owned  subsidiaries,  ASLAN  Pharmaceuticals  Pte.  Ltd.,  ASLAN  Pharmaceuticals  Australia  Pty  Ltd.,  ASLAN  Pharmaceuticals  Hong 
Kong  Limited,  ASLAN  Pharmaceuticals  (Shanghai)  Co.  Ltd.  and  ASLAN  Pharmaceuticals  (USA)  Inc.  were  incorporated  in  Singapore, 
Australia, Hong Kong, China and the United States in April 2010, July 2014, July 2015, May 2016 and October 2018 respectively. 

We have established a joint venture called JAGUAHR Therapeutics Pte. Ltd. with Bukwang Pharmaceutical Co., Ltd. (Bukwang), a leading 
research  and  development  focused  Korean  pharmaceutical  company,  to  develop  antagonists  of  the  aryl  hydrocarbon  receptor  (AhR),  an 
immune checkpoint inhibitor.

Since our inception in 2010, we have devoted substantially all of our resources to acquiring rights to, and developing our product candidates, 
including preclinical studies and clinical trials and providing general and administrative support for our operations. We have not generated 
any revenue from product sales and we do not currently have any products approved for commercialization. We have financed our operations 
through a combination of debt and equity financings and government grants. 

B.

Business Overview. 

We are a clinical-stage immunology focused biopharmaceutical company developing innovative treatments to transform the lives of patients. 

Our portfolio is led by eblasakimab (also known as ASLAN004), a potential first-in-class human monoclonal antibody that binds to the IL-13 
receptor  α1  subunit  (IL-13Rα1),  blocking  signaling  of  two  pro-inflammatory  cytokines,  IL-4  and  IL-13  which  are  central  to  triggering 
symptoms of atopic dermatitis, such as redness and itching of the skin. Eblasakimab has the potential to improve upon current biologics used 
to treat allergic disease.

We  are  currently  conducting  a  Phase  2b  clinical  trial  investigating  eblasakimab  as  a  therapeutic  antibody  for  moderate-to-severe  atopic 
dermatitis (AD). We expect to report topline data from the Phase 2b trial in early July 2023. In September 2021, we announced topline data 
from our Phase 1 multiple ascending dose (MAD) study, conclusively establishing proof of concept for eblasakimab in AD, and supporting a 
potentially differentiated safety and efficacy profile. 

We are also developing farudodstat (also known as ASLAN003), an orally active, potent inhibitor of human dihydroorotate dehydrogenase 
(DHODH) that has the potential to be a best-in-class therapy in autoimmune disease. Inhibition of DHODH is demonstrated to have anti-
inflammatory and immunomodulatory effects that are selective towards rapidly proliferating lymphocytes, making it an attractive target for 
immune-mediated inflammatory diseases, such as alopecia areata (AA). We are planning to conduct a Phase 2 clinical trial in AA starting in 
the second quarter of 2023.

Our Product Candidates

The following table summarizes our product candidate pipeline and discovery programs:

We hold global rights to all of our product candidates with the exception of farudodstat, for which Kyungnam Biopharma (previously known 
as BioGenetics) acquired rights for the Republic of Korea (South Korea).

Eblasakimab. Eblasakimab is a fully human monoclonal antibody that binds to the IL-13 receptor α1 subunit (IL-13Rα1), blocking signaling 
of two pro-inflammatory cytokines, IL-4 and IL-13, which are central to triggering signs and symptoms of AD, such as redness and itching of 
the skin. In March 2021, we announced interim results from a Phase 1 MAD study, reporting data on the 3 dose escalation cohorts – cohorts 1 
(200mg), 2 (400mg) and 3 (600mg) - with subcutaneous administration once weekly for 8 weeks. Eblasakimab demonstrated a statistically 
significant improvement versus placebo in the primary efficacy endpoint of percent change from baseline in the Eczema Area and Severity 
Index (EASI) (at 8 weeks) and also showed statistically significant improvements in other key efficacy endpoints, including EASI-50, EASI-
75, peak pruritus and Patient Oriented Eczema Measure (POEM). In addition, eblasakimab was well-tolerated with no major safety concerns.  

In the first quarter of 2022, we initiated a Phase 2b study in moderate-to-severe AD patients. We expect to report topline data from the Phase
2b  trial  in  early  July  2023.  In  the  fourth  quarter  of  2022,  we  initiated  a  Phase  2  study  of  eblasakimab  in  moderate-to-severe  AD  patients 
previously treated with dupilumab.  We  expect  to  report  topline  data  from  this  Phase  2  trial  in  first  quarter  of  2024.  We  are  also  currently 
evaluating the potential use of eblasakimab in other diseases driven by type 2 inflammation.

Farudodstat.  Farudodstat  is  an  orally  administered,  small-molecule  inhibitor  of  dihydroorotate  dehydrogenase  (DHODH)  and  has  been 
investigated in three phase 1 clinical studies in healthy volunteers, and one Phase 2 study in patients with acute myeloid leukemia (AML). 
The high potency and selectivity of farudodstat, and the favorable safety profile demonstrated in clinical studies to date, may offer best-in-
class potential as a treatment for autoimmune conditions. We plan to investigate farudodstat in a Phase 2 clinical study for the treatment of 
alopecia areata with the study expected to initiate in the second quarter of 2023.

Additional Pipeline Programs. We have established a joint venture called JAGUAHR Therapeutics Pte. Ltd. with Bukwang Pharmaceutical 
Co.,  Ltd.  (Bukwang),  a  leading  research  and  development  focused  Korean  pharmaceutical  company,  to  develop  antagonists  of  the  aryl 
hydrocarbon  receptor  (AhR),  an  immune  checkpoint  inhibitor.  Our  shareholding  in  JAGUAHR  Therapeutics  Pte.  Ltd.  in  April  2021  was 
diluted from 55% to 35%, as a result of which, we no longer held a majority interest.

Our Product Candidates

Eblasakimab (ASLAN004)

Eblasakimab  is  a  fully  human  monoclonal  antibody  that  targets  the  IL-13  receptor  α1  subunit  (IL-13Rα1).  Eblasakimab  is  currently  in 
clinical  development,  and  we  are  not  aware  of  any  other  antibodies  in  clinical  development  targeting  IL-13Rα1.  By  targeting  IL-13Rα1, 
which forms the type 2 receptor complex with IL-4Rα, eblasakimab potently inhibits signaling of both interleukin 4 (IL-4) and interleukin 13 
(IL-13). IL-4 and IL-13 are central to triggering the signs and symptoms of atopic dermatitis, such as redness and itching of the skin, as well 
as signs and symptoms of asthma such as shortness of breath, wheeze and cough. Dupilumab is marketed by Sanofi/Regeneron for moderate-
to-severe  atopic  dermatitis,  moderate-to-severe  asthma,  chronic  rhinosinusitis  with  nasal  polyposis,  eosinophilic  eosophagitis  (EoE)  and 
prurigo nodularis (PN) and is in development for other type 2 driven diseases including chronic spontaneous urticaria (CSU). As we target 
the same pathways as dupilumab, we believe eblasakimab can follow a similar regulatory path. We believe eblasakimab has the potential to 
become a first-in-class inhibitor of the IL-13 receptor and best-in-disease for atopic dermatitis and other type 2 driven allergic disease. By 
targeting  IL-13Rα1,  rather  than  IL-4Rα,  we  believe  eblasakimab  has  the  potential  to  offer  a  differentiated  profile,  including  competitive 
efficacy, lower dosing frequency and a favorable side effect profile.

In the first quarter of 2021, we announced the positive interim readout of our Phase 1 multiple ascending dose (MAD) trial which was then 
followed by the release of our topline results in the third quarter of 2021. In the first quarter of 2022, we initiated a Phase 2b clinical trial 
investigating eblasakimab as a therapeutic antibody for moderate-to-severe atopic dermatitis patients. We expect to report topline data from 
this trial in early July 2023.

In the future, we may also develop eblasakimab in other type 2 driven inflammatory indications, such as eosinophilic esophagitis, chronic 
spontaneous urticaria and prurigo nodularis. 

We licensed worldwide rights for eblasakimab from CSL Limited (CSL) in May 2014.

Mechanism of Action

Eblasakimab has stronger binding to its target receptor than dupilumab relative to ligands IL-13 and IL-4 respectively. Eblasakimab has a 60-
fold higher affinity for the IL-13Rα1 than IL-13, whereas dupilumab only has a three-fold higher affinity for the IL-4Rα than its ligand IL-4. 
This  greater  affinity  difference  between  ligand  and  receptor  binding  may  translate  to  a  lower  required  concentration  of  eblasakimab, 
compared to dupilumab, and may provide improved dosing frequency and efficacy.

While dupilumab can indirectly block IL-13 signaling via the IL-4Rα subunit, eblasakimab’s direct binding of IL-13Rα1 has the potential for 
more efficient blockade of the type 2 receptor compared to binding the IL-4Rα subunit. Formation of the type 2 receptor complex occurs in 2 
steps: the first step involves ligand binding to its receptor and the second step involves the bound receptor binding to the partner receptor to 
form  the  type  2  receptor  heterodimer.  Step  1  is  a  weaker,  lower  affinity  interaction  and  a  rate  limiting  step  while  step  2  is  a  high  affinity 
interaction. By directly blocking the rate limiting step, eblasakimab has the potential to provide more efficient blockade of IL-13 signaling 
versus dupilumab which interferes with step 2, a high affinity interaction. This may translate to lower required concentrations in  vivo  and 
may provide improved dosing frequency and efficacy.

Unlike  dupilumab,  eblasakimab  does  not  bind  to  the  type  1  receptor,  which  contains  the  IL-4Rα  but  not  IL-13Rα1.  We  believe  that  by 
avoiding inhibition of the type 1 receptor, eblasakimab may have fewer side effects than dupilumab, which does bind the type 1 receptor.

Advantages

We believe that eblasakimab has the potential to be a best-in-disease therapy:

•

Validated  mechanism  with  the  potential  for  greater  efficacy  than  IL-13  selective  and  IL-4  selective  inhibitors.  IL-13 
selective inhibitors, such as lebrikizumab and tralokinumab, have shown mixed efficacy in treating allergic inflammation. We 
believe that agents that can block the activity of both IL-4 and IL-13 will be more efficacious as redundancy in signaling is 
removed  by  blocking  type  2  receptor  signaling.  Dupilumab  was  shown  to  be  effective  in  treating  moderate-to-severe  atopic 
dermatitis. Eblasakimab and dupilumab share the same mechanism of action by blocking IL-4 and IL-13 signaling through the 
type 2 receptor. In our Phase 1 MAD clinical trial, the mean change from baseline in EASI in the active arm was 65% versus 
27% in the placebo arm after 8 weeks of treatment with eblasakimab in the modified Intent-to-Treat (mITT) population. 69% 
of  patients  in  the  active  arm  achieved  EASI-75  versus  15%  of  patients  on  the  placebo  arm.  We  believe  the  efficacy  may 
continue to improve with dosing beyond 8 weeks.

•

Potential for less frequent dosing. Dupilumab may require significantly higher steady state concentrations than eblasakimab 
for  full  target  inhibition,  which  may  allow  for  less  frequent  dosing.  Dupilumab  is  dosed  once  every  two  weeks  via 
subcutaneous  injection.  Eblasakimab  may  offer  the  potential  for  monthly  dosing  and  this  is  being  investigated  in  clinical 
development. A reduced injection frequency would provide patients with greater convenience.

Potential for faster onset of action. In the clinic, eblasakimab delivered intravenously demonstrated a rapid onset of action 
with  full  receptor  occupancy  and  complete  inhibition  of  a  key  downstream  biomarker  of  IL-13  and  IL-4  signaling,  STAT6, 
within one hour of dosing, closely reflecting the data obtained in the cynomolgus monkey. In our Phase 1 MAD study, we saw 
a rapid fall in EASI, pruritis (itch) and POEM after the first dose which continued through the treatment period.

Potential for improved safety profile.  In  published  clinical  studies  in  atopic  dermatitis,  dupilumab  demonstrated  persistent 
conjunctivitis in 5-28% of patients, often requiring topical ocular treatment with tacrolimus or steroids. As well as blocking the 
type  2  receptor,  dupilumab  also  blocks  the  type  1  receptor,  which  may  drive  certain  T  cells  to  release  pro-inflammatory 
cytokines, which may be responsible for these high rates of conjunctivitis. Treatment with eblasakimab  may  result  in  lower 
rates of conjunctivitis as it only blocks the type 2 receptor and does not block the type 1 receptor.  

Potential  for  increased  drug  stability. Dupilumab  can  be  stored  for  a  maximum  of  14  days  at  room  temperature  (25°C  or 
77°F) and cannot be stored above room temperature. As dupilumab can be self-administered, it may require special storage and 
handling when travelling. Eblasakimab may have increased drug stability and therefore greater storage flexibility.

Potential  for  rapid  control  of  itch:  In  addition  to  driving  inflammation  in  AD  patients,  IL-4  and  IL-13  can  enhance  the 
neuronal  itch  response  via  the  type  2  receptor  expressed  on  itch-specific  sensory  neurons.  Through  blockade  of  the  type  2 
receptor, eblasakimab could potentially decrease sensitivity to itch and provide rapid itch relief in AD patients. In translational 
studies  of  ex  vivo  human  sensory  neurons,  eblasakimab  significantly  reduced  neuronal  responses  to  IL‑4,  IL‑13,  and  their 
combination by an average of 40% (p<0.0001). These results provide a molecular basis for the significant reduction of pruritus 
scores observed in eblasakimab-treated moderate-to-severe AD patients in the Phase 1b clinical trial.

Market Opportunity

Market Opportunity in Moderate-to-Severe Atopic Dermatitis

Atopic dermatitis is the most common form of eczema, affecting over 200 million patients worldwide, characterized by red inflamed skin and 
severe  daytime  and  nighttime  itching,  which  can  severely  impact  patients’  quality  of  life.  Over  30%  of  atopic  dermatitis  patients  are 
considered moderate-to-severe, for which currently available therapeutics are limited and management is challenging in the majority of cases.

Treatment  options  for  patients  with  mild-to-moderate  disease  have  historically  focused  on  topical  therapies  including  topical  steroids  and 
topical  calcineurin  inhibitors.  In  December  2016,  the  U.S.  FDA  granted  approval  for  crisaborole  (developed  by  Pfizer  Inc.),  a  topical 
treatment for mild-to-moderate atopic dermatitis. In March 2017, the U.S. FDA granted approval for dupilumab (developed by Sanofi S.A. 
and Regeneron Pharmaceuticals, Inc.) for adults with moderate-to-severe atopic dermatitis. Until recently, dupilumab was the only approved 
biologic therapy available and has been driving significant growth in the market, which is expected to reach $39 billion by 2031. Dupilumab 
is  currently  approved  for  the  treatment  of  atopic  dermatitis  in  adults  and  pediatric  patients  6  months  of  age  or  older.  In  December  2021, 
tralokinumab (Leo Pharma A/S) was approved by the FDA for adults with moderate-to-severe atopic dermatitis. However there remains a 
significant unmet need, with only 35% of patients treated with dupilumab achieving an optimal response and conjunctivitis reported in 5-28% 
to patients in clinical practice.

51

In 2022, two small molecule inhibitors of Janus kinase (JAK), abrocitinib (Pfizer Inc.) and upadacitinib (AbbVie Inc), were approved by the 
U.S. FDA for treatment of moderate-to-severe atopic dermatitis, however their use is limited to patients with refractory, moderate-to-severe 
AD  whose  disease  is  not  adequately  controlled  with  other  systemic  drug  products,  including  biologics,  or  when  use  of  those  therapies  is 
inadvisable. Abrocitinib is currently approved for the treatment of atopic dermatitis in adults and upadacitinib is approved for the treatment 
of atopic dermatitis in adults and pediatric patients 12 years of age and older. Moreover, abrocitinib and upadacitinib carry three black box 
warnings for safety: higher rates of cardiovascular events such as heart attack or stroke, cancer, and blood clots.

Market Opportunity in Type 2 Driven Diseases

The type 2 immune response is dominant against environment-related antigens. While important in protection against helminths and in tissue 
repair, uncontrolled type 2 responses are implicated in allergy and atopic diseases. The type 2 response is orchestrated by key cytokines IL-4, 
IL-5 and IL-13 which are produced by type 2 T helper cells and type 2 innate lymphoid cells. This results in production of Immunoglobulin E 
(IgE)  and  activation  of  mast  cells  and  eosinophils.  Several  conditions  including  asthma,  atopic  dermatitis,  allergic  rhinitis,  eosinophilic 
gastrointestinal  disorders  are  driven  by  type  2  inflammation  and  can  be  grouped  as  type  2  driven  diseases.  The  market  for  type  2  driven 
diseases is large and continues to grow with over 500 million patients affected worldwide. 

The development of dupilumab has demonstrated the importance of IL-4 and IL-13 signaling in multiple type 2 driven diseases. By targeting 
the IL-13 receptor, we believe eblasakimab has the potential to be an effective treatment in a similar range of diseases.

Preclinical and Clinical Development

Eblasakimab  is  a  fully  human  IgG4  monoclonal  antibody  that  specifically  binds  to  the  human  IL-13Rα1  protein  and  was  originally  made 
using the Medarex mouse technology. The antibody was isolated and optimized to have picomolar binding affinity by CSL Behring.

Eblasakimab is a potent inhibitor of both IL-4 and IL-13 signaling with a binding affinity in the picomolar range for human IL-13Rα1. In in 
vitro  assays,  eblasakimab  inhibits  the  release  of  key  allergic  mediators,  such  as  thymus  and  activation  regulated  chemokine  (TARC)  that 
maintain and amplify allergic reactions initiated by IL-4 and IL-13.

Eblasakimab potently inhibits TARC release from human cells

Single Ascending Dose Clinical Trial in Healthy Volunteers

In June 2019, we announced the successful completion of a Single Ascending Dose (SAD) clinical trial testing intravenous and subcutaneous 
administration of eblasakimab in healthy volunteers. The first subject was enrolled in October 2018 and the last subject was dosed in March
2019.  The  single  ascending  dose  clinical  trial  explored  the  safety,  tolerability,  pharmacokinetic  profile  and  pharmacodynamic  profile  of 
eblasakimab when dosed via both intravenous and subcutaneous routes of administration. The clinical trial consisted of 10 cohorts with up to 
six patients per cohort.

Phase 1 eblasakimab Single Ascending Dose Trial Design (completed)

Eblasakimab  was  well  tolerated  at  all  dose  levels  via  both  intravenous  and  subcutaneous  routes  of  administration.  No  conjunctivitis  was 
noted in any subjects dosed with eblasakimab and there were no adverse events that led to discontinuation at any dose level.

The SAD clinical trial also measured the pharmacokinetic profile of eblasakimab and pharmacodynamic markers of inhibiting IL-4 and IL-13 
binding to the IL-13Rα1, such as IL-13α1 receptor occupancy and inhibition of phosphorylation of STAT6 (pSTAT6), a key marker of the 
signal transduction in allergic inflammation immediately downstream of IL-4 and IL-13 binding to the type 2 receptor. In mouse models of 
allergic inflammation, the knockout of STAT6 completely abolished allergic inflammation.

When greater than or equal to 600mg eblasakimab was administered intravenously (10mg/kg) it demonstrated 100% receptor occupancy and 
complete inhibition of STAT6 phosphorylation in less than 1 hour after dosing. These effects were maintained for over 29 days following a 
single dose of eblasakimab, suggesting monthly dosing may be achievable. The rapid inhibition of IL-4 and IL-13 signaling by eblasakimab 
could also lead to a fast onset of symptom relief in atopic dermatitis patients.

Multiple Ascending Dose Clinical Trial in Moderate-to-Severe Atopic Dermatitis

In October 2019, we initiated a MAD clinical trial testing eblasakimab in moderate-to-severe AD patients. The randomized, double-blind, 
placebo-controlled trial evaluated three doses (200mg, 400mg and 600mg) of eblasakimab delivered weekly via subcutaneous injection, with 
approximately 8 patients in each cohort. Based on a review of blinded safety data completed in January 2021, the highest dose, 600mg, was 
selected for the expansion cohort, which recruited 27 additional patients. Patients were dosed weekly for eight weeks to determine safety and 
the  efficacy  of  eblasakimab.  The  primary  endpoint  was  safety  and  tolerability.  Secondary  endpoints  included  efficacy  at  eight  weeks  as 
measured by improvement in the Eczema Area and Severity Index (EASI) score, EASI-50, EASI-75, Investigators Global Assessment (IGA), 
pruritis numeric rating scale (P-NRS) and Patient-Oriented Eczema Measure (POEM).

The trial was designed with 80% power to detect a 39% improvement in EASI compared to placebo at eight weeks.

The  trial  recruited  approximately  50  moderate-to-severe  atopic  dermatitis  patients  and  recruitment  into  the  expansion  cohort  started  in 
January 2021. We reported topline data from this trial in the third quarter of 2021. After completion of the MAD trial, we initiated a Phase 2b 
dose-range finding trial in atopic dermatitis patients.

Eblasakimab MAD Design in Moderate-to-Severe Atopic Dermatitis

In March 2021, we reported positive interim unblinded data from the first three dose cohorts (200mg, 400mg and 600mg) of the ongoing 
MAD  clinical  trial.  The  first  three  cohorts  randomized  25  patients  from  the  United  States,  Australia  and  Singapore.  Three  patients 
discontinued the trial due to restrictions imposed in response to COVID-19. Of the remaining 22 patients, 18 completed at least 29 days of 
dosing and assessment and were evaluable for efficacy. The average baseline EASI score of patients was 32.5 and the average IGA score was 
3.4  (n=18).  At  week  8,  the  average  reduction  in  EASI  from  baseline  at  therapeutic  doses  (400mg  and  600mg  cohorts)  was  74%  (n=9) 
compared to 42% (n=5) for patients on placebo. 89% of patients achieved EASI-50 versus 40% on placebo; 67% achieved EASI-75 versus 
0% on placebo; 56% achieved EASI-90 versus 0% on placebo; and 22% of patients achieved IGA of 0 or 1 versus 0% on placebo. Peak 
pruritus improved after just one dose and continued to improve by an average of 46% relative to baseline at week 8 compared to 16% for 
patients on placebo. The proportion of patients with adverse events and treatment-related adverse events were similar across treatment and 
placebo arms. There were no treatment-related adverse events in the active arm that led to discontinuation.

In  September  2021,  we  announced  positive  topline  data  from  the  completed  study  conclusively  establishing  proof-of-concept  for 
eblasakimab in AD. Efficacy analysis was performed on a modified Intent-to-Treat (mITT) population, excluding 9 patients from a single site 
because their eligibility could not be confirmed and was pre-specified and defined prior to unblinding. In both ITT and mITT populations, 
eblasakimab achieved a statistically significant improvement versus placebo in the primary efficacy endpoint of percent change from baseline 
in  the  Eczema  Area  Severity  Index  (EASI),  and,  although  the  study  was  not  designed  to  do  so,  also  showed  statistically  significant 
improvements in other key efficacy endpoints, such as EASI-50, EASI-75 and POEM.

In the mITT population, the average reduction from baseline in EASI at 8 weeks was 65% (n=16) compared to 27% (n=13) for patients on 
placebo  (one-sided  p-value  of  0.014),  and  69%  achieved  EASI-75  versus  15%  on  placebo  (one-sided  p-value  of  0.005).  44%  of  patients 
achieved Investigator's Global Assessment (IGA) of 0 or 1 versus 15% on placebo. Peak pruritus improved by an average of 49% (n=16) 
relative to baseline at 8 weeks compared to 6% for patients on placebo.

Phase 2b Dose-Ranging Clinical Trial in Moderate-to-Severe Atopic Dermatitis

TREK-AD  is  a  randomized,  double-blind,  placebo-controlled,  multicenter,  dose-ranging  trial  to  evaluate  the  efficacy  and  safety  of 
eblasakimab in adult patients with moderate-to-severe AD. The study will evaluate the efficacy and safety of eblasakimab as monotherapy in 
adult patients with moderate-to-severe AD who are candidates for systemic therapy. The study has 5 treatment arms (4 active treatment arms 
and 1 placebo arm) evaluating eblasakimab administered as subcutaneous injections at three dose levels and two dosing frequencies (every 2 
weeks – q2w, or every 4 weeks – q4w) after 2 or 3 loading doses:

The study has enrolled approximately 300 adult patients across over 80 sites in the United States, Europe and Asia and consists of a 16-week 
treatment period and 12-week safety follow-up period. The primary efficacy endpoint is percentage change in EASI score from baseline to 
Week 16. Other key secondary endpoints at Week 16 include proportion of patients achieving EASI score reductions of 50% (EASI-50) or 
75% (EASI-75), validated IGA (vIGA) of clear or almost clear (IGA 0/1 response on 5-point scale), and reductions in P-NRS, and various 
patient reported outcomes including POEM, as well as safety and tolerability. The topline data readout is expected to be in early July 2023.

Phase 2 Trial in Moderate-to-Severe Atopic Dermatitis Patients Previously Treated with Dupilumab

TREK-DX  is  a  randomized,  double-blinded,  placebo-controlled  Phase  2  trial  to  evaluate  the  efficacy  of  eblasakimab  in  dupilumab-
experienced moderate-to-severe AD patients. Due to the growing use of dupilumab in moderate-to-severe AD patients, this study is designed 
to establish the potential of eblasakimab in patients who have discontinued dupilumab treatment for any reason, including inadequate control 
of AD, loss of access or an adverse event. 

The study is expected to enroll approximately 75 patients randomized 2:1 to receive either eblasakimab 400mg every week or placebo and 
will consist of a 16-week treatment period and 8-week safety follow-up period. The primary efficacy endpoint is percentage change in EASI 
score from baseline to Week 16. Other key secondary endpoints at Week 16 include proportion of patients achieving EASI score reductions 
of  50%  (EASI-50)  or  75%  (EASI-75),  vIGA  of  clear  or  almost  clear  (IGA  0/1  response  on  5-point  scale),  and  reductions  in  P-NRS,  and 
various patient reported outcomes including POEM, as well as safety and tolerability. The topline data readout is expected to be in the first 
quarter of 2024.

Farudodstat (ASLAN003)

Farudodstat  is  an  orally  active,  potent  inhibitor  of  DHODH  which  was  designed  to  address  the  limitations  of  first  generation  DHODH 
inhibitors  in  inflammatory  autoimmune  diseases.  Leflunomide  and  teriflunomide,  which  is  the  active  metabolite  of  leflunomide,  are  first 
generation  DHODH  inhibitors,  approved  in  the  United  States,  Europe  and  Asia  for  the  treatment  of  rheumatoid  arthritis  and  multiple 
sclerosis,  respectively.  These  molecules  are  less  potent  inhibitors  of  DHODH  as  compared  to  farudodstat  and  are  sufficient  to  slow  the 
proliferation of inflammatory cells and therefore adequate in treating chronic inflammatory disorders. 

However,  these  molecules  are  known  to  have  off-target  activities,  extremely  long  wash-out  period  and  have  black  box  warnings  for 
hepatotoxicity  and  reproductive  toxicity,  requiring  close  patient  monitoring  or  restricting  use  altogether.  In  contrast,  farudodstat  is 
structurally distinct from and up to two orders of magnitude more potent at inhibiting DHODH than teriflunomide. It has a half-life of 16 
hours with no accumulation, allowing for rapid clearance on cessation of treatment. In contrast to teriflunomide, farudodstat was not found to 
be hepatotoxic in rodent studies. 

We licensed farudodstat from Almirall, S.A. (Almirall) in 2012 after Almirall’s completion of a Phase 1 single ascending dose clinical trial, 
in  which  the  drug  was  well-tolerated  in  healthy  volunteers.  We  then  conducted  two  additional  Phase  1  clinical  trials,  exploring  multiple 
ascending  doses  and  fed/fasted  comparison  in  healthy  volunteers.  These  trials  demonstrated  that  the  drug  was  well-tolerated  and  had  the 
potential for once daily dosing. We subsequently explored the activity of farudodstat in AML, by conducting a small Phase 2 study, which 
showed  some  signs  of  activity  in  patients  with  AML  and  demonstrated  that  farudodstat  was  well-tolerated  in  this  population.  We  plan  to 
investigate farudodstat in a Phase 2a proof of concept clinical study for the treatment of alopecia areata with the study expected to initiate in 
the first half of 2023.

Mechanism of Action

Pyrimidines are nucleotides and are essential building blocks for the production of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) 
in  mammalian  cells.  Rapidly  proliferating  cells,  such  as  immune  cells  in  response  to  disease,  require  increased  levels  of  adenosine 
triphosphate (ATP) and pyrimidines for growth and replication. Farudodstat is an inhibitor of DHODH, which is the enzyme controlling the 
conversion of dihydroorotate (DHO) to orotate, the rate limiting step in the de novo synthesis of uridine monophosphate (UMP) which is a 
pyrimidine precursor. Inhibition of DHODH therefore restricts the pyrimidine pool available to rapidly proliferating cells. DHODH is located 
in the mitochondria and during manufacture of nucleotides it also contributes to the production of ATP. Inhibition of DHODH depletes the 
intracellular pool of pyrimidines and contributes to lower levels of ATP, which inhibits the cell’s ability to replicate. Importantly, normally 
functioning,  non-proliferating  cells  can  utilize  salvage  pathways  to  obtain  ATP  and  pyrimidines,  so  the  effects  of  DHODH  inhibition  are 
expected to selectively affect only the types of rapidly proliferating cells implicated in disease. The metabolic stress induced in response to 
DHODH  inhibition  leads  to  the  reduction  of  pro-inflammatory  cytokine  secretion,  including  interferon  gamma  (IFNγ),  and  to  increased 
apoptosis, and these mechanisms are implicated in a number of autoimmune diseases, including AA, which have shared genetics and immune 
pathways. This broad mechanism may have utility in several distinct therapeutic areas. In T-cell mediated inflammatory autoimmune diseases 
such as rheumatoid arthritis and multiple sclerosis, inhibition of DHODH to arrest the proliferation of autoreactive lymphocytes is a well-
established treatment strategy.

56

 
 
 
 
 
 
The  causes  of  AA  are  not  fully  understood,  but  it  is  believed  to  result  from  a  loss  of  immune  privilege  in  the  hair  follicle  following  a 
triggering event (e.g. stress, infection, trauma) mediated by IFNγ. This leads to an upregulation of inflammatory cytokine signaling, which 
results in an autoimmune-mediated hair loss. In AA, the local increase in IFNγ leads to collapse of immune privilege around the hair follicle 
and a Th1 inflammatory response towards the hair bulb, resulting in a premature start of the hair loss cycle and hair follicle degeneration.
DHODH inhibition reduces cytokine secretion and Th1 cell differentiation, thereby directly blocking the key drivers of AA.

Advantages

We believe that farudodstat has the potential to be a best-in-class DHODH inhibitor in autoimmune disease due to the following competitive 
advantages:

•

•

Potent inhibition of DHODH. The binding affinity of farudodstat to DHODH is up to two orders of magnitude stronger than 
first generation DHODH inhibitors, such as leflunomide and teriflunomide, and other clinical stage compounds.

Addresses the toxicities associated with first generation inhibitors. Existing DHODH inhibitors, such as leflunomide and 
teriflunomide,  are  associated  with  significant  off-target  toxicities  and  carry  black  box  warnings  for  hepatotoxicity  and 
reproductive  toxicity.  Farudodstat  has  been  found  to  be  well  tolerated  in  Phase  1  and  Phase  2  studies.  In  rats  and  mice, 
farudodstat  was  not  hepatotoxic  at  doses  three  times  higher  than  the  doses  of  teriflunomide  at  which  hepatotoxicity  was 
observed,  despite  farudodstat  being  over  30  times  more  potent  at  inhibiting  DHODH,  and  this  study  suggested  that  the  on-
target mechanism of DHODH inhibition was not responsible for the hepatotoxicity observed with teriflunomide. Furthermore, 
in  work  undertaken  by  Liverpool  University,  a  world  leading  center  for  hepatotoxicity,  scientists  evaluated  the  hepatotoxic 
potential of a panel of six DHODH inhibitors in two hepatic in vitro models. In one model, farudodstat was shown to be the 
least toxic compound tested despite being one of the most potent DHODH inhibitors, while teriflunomide and leflunomide were 
equally the most toxic compounds tested.

• Highly favorable pharmacokinetic (PK) profile. Both leflunomide and teriflunomide take between three and four weeks to 
build  to  therapeutic  levels  and  two  years  to  clear  completely  after  dosing  is  stopped.  In  contrast,  farudodstat  reaches  full 
exposure in 24 hours with a half-life of 16 hours allowing rapid clearance following cessation of treatment. Farudodstat shows 
a linear, dose-proportional PK profile and allows for once-daily, oral dosing which is important in ensuring patient compliance.

Market Opportunity in Autoimmune Disease

The autoimmune diseases market is large and continues to grow, with indications such as psoriasis and inflammatory bowel disease (IBD) 
affecting as many as 2% and 1% of the United States population, respectively. In 2021, the global autoimmune disease therapeutics market
was valued at $55 billion and is forecast to reach $114 billion by 2028. Many diseases have similar or related underlying pathogenesis, and 
some have few or no effective pharmaceutical treatment options. 

Autoimmune diseases of the skin include multiple indications such as psoriasis, alopecia areata, vitiligo and pemphigus. Patient symptoms 
vary  based  on  the  specific  conditions  but  can  include  skin  lesions,  blisters,  plaque  and  skin  scarring.  Current  treatments  are  limited  to 
systemic corticosteroids and immunosuppressive treatments with limited safe and effective long term treatment options.

The broad immunomodulatory and anti-inflammatory properties of farudodstat may have utility in several different diseases and may offer a 
safe  and  convenient  treatment  option  for  patients  with  these  diseases.  Other  than  the  first  generation  DHODH  inhibitors,  leflunomide and 
teriflunomide,  approved  in  rheumatoid  arthritis  and  multiple  sclerosis  respectively,  there  are  no  DHODH  inhibitors  approved  for  the 
treatment of autoimmune disease, presenting a compelling opportunity for farudodstat.

Market Opportunity in Alopecia Areata

Alopecia  areata  is  a  common,  inflammatory,  non-scarring,  autoimmune-mediated  hair  loss  condition  with  limited  treatment  options.  The 
cumulative lifetime prevalence of AA is estimated at about 2% with 2.6M cases in the US and 2.1M in EU5 (France, Germany, Italy, Spain 
and the United Kingdom) market. Among the US population, there are currently 700,000 prevalent cases of AA with 25% of patients having 
severe  disease  and  62%  of  all  patients  receiving  drug  treatment.    Until  recently  there  were  no  approved  systemic  treatments  for  alopecia 
areata. 

57

Baricitinib (Olumiant®), a Janus Kinase (JAK) inhibitor, was approved by FDA in 2022 for the treatment of adult patients with severe AA. 
In a Phase 3 study, up to 35% of patients who received baricitinib achieved adequate scalp hair coverage. However, baricitinib has a black 
box  warning  for  serious  infections,  mortality,  malignancy,  major  adverse  cardiovascular  events,  and  thrombosis.  Other  drugs  currently  in 
Phase 3 clinical studies in AA are also JAK inhibitors and, if approved, are expected to have the same black box warnings as baricitinib. 
Other clinical-stage treatments are few and to our knowledge no other DHODH inhibitors are currently being investigated for the treatment 
of AA. Hence, there remains an unmet need for safe and effective treatment options for AA, and farudodstat is the only DHODH inhibitor 
currently in clinical development in this disease.

Preclinical and Clinical Development

We assessed the potency of farudodstat using three standard assays: cell free, human primary cell, and human whole blood. The table below 
shows that farudodstat is more potent than teriflunomide. The IC50 value is the concentration of the drug required to produce 50% inhibition 
of response in the assay.

To address the black box warnings for hepatotoxicity associated with the first generation DHODH inhibitors leflunomide and teriflunomide, 
in  vitro  studies  were  conducted  to  further  investigate  the  hepatotoxicity  of  several  DHODH  inhibitors.  The  study  demonstrated  that 
farudodstat has the lowest potential for hepatotoxicity out of 6 approved and clinical stage DHODH inhibitors.

In  established  animal  models  of  multiple  sclerosis  (Experimental  Autoimmune  Encephalomyelitis  -  EAE)  and  rheumatoid  arthritis 
(Adjuvant-Induced Arthritis - AIA) farudodstat inhibited disease progression in a dose-dependent manner.

Farudodstat’s  mechanism  of  action  was  tested  in  an  established  ex  vivo  human  model  of  AA.  Micro-dissected  hair  follicles  from  human 
scalp  were  tested  in  ex  vivo  culture  systems  which  preserve  the  architecture  of  the  hair  follicle  and  allow  investigation  of  molecular 
mechanisms of immune privilege (IP) collapse- a key precursor to AA. IP collapse is characterized by expansion of T cells in hair follicle, 
IFNγ expression and upregulation of major histocompatibility complex (MHC) I and II proteins. Farudodstat treatment at clinically relevant 
doses,  significantly  inhibited  expansion  of  CD3+  T  cells  and  downregulated  MHC  I  and  MHC  II  expression  after  AA  induction.  These 
results provide evidence 

58

 
 
 
 
 
 
 
 
 
that  farudodstat  could  have  the  potential  to  restore  immune  privilege  by  inhibiting  the  key  processes  of  T  cell  expansion  and  MHC 
expression.

Our Phase 1 single and multiple ascending dose clinical trials of farudodstat, which were conducted with 95 healthy subjects, demonstrated 
dose proportional pharmacokinetics and no accumulation in the body. After a single 100 mg oral dose of farudodstat, the plasma levels of the 
drug in Caucasians and Asians were highly similar and demonstrated stable drug levels in plasma at multiple doses. Farudodstat also reached 
steady state within about four days of dosing and with minimal accumulation.

Phase 2a Proof of Concept Study in Alopecia Areata

We are planning to initiate a Phase 2a, proof of concept study to investigate the efficacy and safety of farudodstat compared to placebo in 
adult alopecia areata patients. The study is expected to recruit around 60 patients in the US who will be randomized in 2:1 onto one of the 
two arms (100mg farudodstat  twice-daily  and  placebo).  An  initial  treatment  period  of  12  weeks  will  be  followed  by  a  12-week  crossover
treatment period. An interim analysis will evaluate safety and efficacy after the first 12-week treatment period, and the efficacy assessment 
will be based on the percent of change from baseline in the Severity of Alopecia Tool (SALT) score at week 12.

Discovery Pipeline

Joint Venture to Develop Novel Pre-clinical AhR Antagonists

In  September  2019,  we  announced  that  we  had  established  a  new  joint  venture  with  Bukwang  to  develop  preclinical  aryl  hydrocarbon 
receptor  (AhR)  antagonists  from  our  early  stage  pipeline.  The  joint  venture,  JAGUAHR  Therapeutics  Pte.  Ltd.  (JAGUAHR),  focuses  on 
developing new immuno-oncology therapeutics for global markets targeting the AhR pathway.

AhR  is  a  druggable  transcription  factor  that  acts  as  a  master  regulator  of  the  immune  system.  The  enzymes  IDO1,  IDO2  and  TDO  are 
frequently overexpressed in numerous tumor types and convert tryptophan into kynurenine (KYN) in the tumor microenvironment. KYN is 
then actively transported into dendritic cells and effector T-cells that are mobilized to detect and kill tumor cells. KYN signaling via AhR in 
these cell types converts them into regulatory T-cells, suppressing the immune system and preventing it from attacking tumor cells. Research 
has demonstrated that the unique advantages of AhR antagonists include broadly inhibiting the signaling of all AhR ligands produced by any 
enzyme that metabolizes tryptophan, and robust activation of the immune response to kill cancer cells.

Pursuant to the terms of the agreement establishing the joint venture agreement (the JV Agreement), we transferred the global rights to all of 
the  assets  related  to  AhR  technology,  originally  discovered  and  developed  by  ASLAN  and  its  collaborators,  into  JAGUAHR.  Bukwang 
invested a total of $5.0 million in JAGUAHR in two tranches to fund lead optimization and candidate selection. Until the IND application is 
filed, we retain the rights to buy back the assets related to AhR technology at a price equal to three times the amount invested by Bukwang. 

At inception we owned a controlling stake 55% of the JAGUAHR entity. The first tranche of $2.5 million was received by JAGUAHR from 
Bukwang in October 2019 and the second tranche of $2.5 million was received on April 28, 2021. In consideration for such payment, our 
shareholding of JAGUAHR was diluted to 35% from 55%.

Competition

Our  industry  is  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  While  we  believe  that  our  knowledge, 
experience  and  scientific  resources  provide  us  with  competitive  advantages,  we  face  substantial  competition  from  major  pharmaceutical 
companies,  specialty  pharmaceutical  companies  and  biotechnology  companies  worldwide.  Many  of  our  competitors  have  significantly 
greater financial, technical and human resources. Small and early-stage companies may also prove to be significant competitors, particularly 
through  collaborative  arrangements  with  large  and  established  companies.  As  a  result,  our  competitors  may  discover,  develop,  license  or 
commercialize products before or more successfully than we do.

We face competition with respect to our current product candidates, and will face competition with respect to future product candidates, from 
segments of the pharmaceutical, biotechnology and other related sectors, as well as from academic institutions.

The  acquisition  or  licensing  of  pharmaceutical  products  is  also  very  competitive.  If  we  seek  to  acquire  or  license  products,  we  will  face 
substantial competition from a number of more established companies, some of which have acknowledged strategies to license or acquire 
products  and  many  of  which  are  bigger  than  us  and  have  more  institutional  experience  and  greater  cash  flows  than  we  have.  These  more 
established companies may have competitive advantages over us, as may other emerging companies taking similar or different approaches to 
product  licenses  or  acquisitions.  In  addition,  a  number  of  established  research-based  pharmaceutical  and  biotechnology  companies  may 
acquire  products  in  late  stages  of  development  to  augment  their  internal  product  lines,  which  may  provide  those  companies  with  an  even 
greater competitive advantage.

If  our  product  candidates  are  approved,  they  may  compete  with  currently  marketed  drugs  and  therapies  used  for  treatment  of  the  same 
indications, and potentially with drug candidates currently in development. The key competitive factors affecting the success of any approved 
product include its efficacy, safety profile, price, method of administration and level of promotional activity.

Certain competitor drugs and drug candidates to eblasakimab and farudodstat include:

Eblasakimab

• We are not aware of any other drugs targeting IL-13Rα1.

•

•

•

•

Dupilumab from Sanofi S.A. and Regeneron Pharmaceuticals, Inc. is approved to treat moderate-to-severe atopic dermatitis, 
moderate-to-severe asthma, chronic rhinosinusitis with nasal polyposis eosinophilic esophagitis and prurigo nodularis.

Tralokinumab from Leo Pharma A/S is approved to treat moderate-to-severe atopic dermatitis.

In addition to the biologics in the market, there are two newly approved JAK inhibitor drugs targeting AD. Abrocitinib from 
Pfizer Inc. and upadacitinib from AbbVie Inc. are both approved for the treatment of adults living with refractory, moderate-to-
severe AD, whose disease is not adequately controlled with other systemic drug products, including biologics, or when use of 
those therapies is inadvisable. 

Lebrikizumab targets the IL-13 ligand and being developed by Dermira, Inc./Eli Lilly. Lebrikizumab recently completed Phase 
3 clinical trials in atopic dermatitis and a BLA was submitted to the US FDA for AD treatment in November 2022. 

Farudodstat

•

•

In 2022, baricitinib (Olumiant®), a Janus Kinase (JAK) inhibitor, was the first system therapy to be approved by the FDA for 
AA. Several other JAK inhibitors including ritlecitinib, deuruxolitinib, jaktinib, SHR0302 and deucravacitinib are currently in 
clinical development and, if approved, will pose direct competition to baricitinib. 

Besides JAK inhibitors, there are few other drugs currently in advanced clinical development for alopecia areata. These include 
daxdilimab (anti ILT7), etrasimod (S1P inhibitor) and EQ101 (IL-2/9/15 inhibitor).

• We are not aware of any DHODH inhibitors currently in clinical development for AA. Teriflunomide and leflunomide from 
Sanofi  S.A.  are  DHODH  inhibitors  approved  for  the  treatment  of  multiple  sclerosis  and  rheumatoid  arthritis  respectively. 
Vidofludimus (Immunic, Inc) and KIO-101 (Kiora Pharmaceuticals, Inc) are DHODH inhibitors currently in development for 
multiple sclerosis and ocular manifestations of rheumatoid arthritis, respectively.

61

Manufacturing

All of our clinical supplies are manufactured in accordance with current good manufacturing practices (cGMP) using high quality contract 
manufacturing  organizations,  and  we  plan  to  continue  to  rely  on  contract  manufacturing  organizations  for  our  production  needs  for  the 
foreseeable future. We do not have internal manufacturing capabilities for small molecules or biological drugs and we do not intend to build 
or acquire infrastructure for manufacturing our product candidates for clinical or commercial supply.

All facilities and techniques used in the manufacture of products for clinical use or for sale in China must be operated in conformity with
good manufacturing practice guidelines as established by the National Medicinal Products Administration (NMPA). Failure to comply with 
applicable requirements could result in the termination of manufacturing and significant fines. 

License and Collaboration Agreements

License Agreement with CSL

On May 12, 2014, we entered into a license agreement with CSL, which was subsequently amended and restated on May 31, 2019, pursuant 
to which we obtained an exclusive, worldwide license to certain intellectual property owned or licensed by CSL, including patents and know-
how,  to  develop,  manufacture  for  clinical  trials  and  commercialize  eblasakimab  for  the  treatment,  diagnosis  or  prevention  of  diseases  or 
conditions  in  humans.  Our  development  under  such  agreement  is  currently  focused  on  the  treatment  of  respiratory  and  inflammatory 
conditions, and in particular, atopic dermatitis.

Under  the  amended  agreement,  we  are  generally  obligated  to  use  diligent  efforts  to  develop  eblasakimab products in accordance with the 
development plan, to obtain marketing approvals for eblasakimab products worldwide and to commercialize eblasakimab products, either by 
ourselves or through sublicensees. We are currently conducting a Phase 2b clinical trial investigating eblasakimab as a therapeutic antibody 
for  moderate-to-severe  atopic  dermatitis.  In  consideration  of  the  rights  granted  to  us  under  the  amended  agreement,  we  will  make  a  first 
payment of $30 million to CSL upon commencement of a Phase 3 clinical trial of eblasakimab. We will also be required to pay up to an 
aggregate of $95 million to CSL if certain regulatory milestones are achieved, up to an aggregate of $655 million if certain sales milestones 
are achieved and tiered royalties on net sales of eblasakimab products ranging between a mid-single digit percentage and 10%. We are also 
responsible for all payments to third-party licensors to CSL, to the extent such obligations relate to our exploitation of the rights licensed 
under CSL’s agreement with those parties and sublicensed to us under the amended agreement. For the year ended December 31, 2022, the 
Company made a milestone payment of $1 million to CSL in fulfilment of our obligation under the CSL agreement to be responsible for 
payment  required  to  be  made  by  CSL  to  third  party  licensors  of  technology  relating  to  exploitation  of  the  rights  subject  to  the  CSL 
agreement.  The  commencement  of  the  first  Phase  2  clinical  trial,  being  the  Phase  2b  trial  investigating  eblasakimabas  as  a  therapeutic 
antibody for moderate-to-severe atopic dermatitis. The trial is still ongoing and no further milestones have been met.

The amended agreement continues, unless terminated earlier in accordance with its terms, until the last to occur, in the relevant country, on a 
country-by-country and product-by-product basis, of: (a) expiry of the last valid CSL patent covering such product in such country, (b) 12 
years from first commercial sale of such product in such country or (c) lapse of data or market exclusivity for such product in such country.

In  addition  to  certain  other  customary  termination  bases,  either  party  may  terminate  the  amended  agreement  (i)  in  the  event  of  the  other 
party’s material breach of the agreement that remains uncured for a specified period of time, (ii) under certain circumstances related to the 
safety of eblasakimab or (iii) if the other party becomes insolvent. In addition, we may terminate the agreement under certain circumstances 
related to the development and commercialization of eblasakimab.

If  the  agreement  is  terminated  in  certain  circumstances  and  CSL  subsequently  commercializes  eblasakimab  products  or  grants  third-party 
rights to commercialize eblasakimab products, then CSL will pay us royalties on the net sales of eblasakimab products or share a low double 
digit percentage of license revenue with us (whichever is applicable). To the extent that CSL is required to pay us royalties following the 
termination  of  the  agreement,  such  royalties  will  range  from  a  mid-single  digit  percentage  to  mid-double  digit  percentage  of  net  sales  of 
eblasakimab  products,  depending  on  the  cause  of  termination  and  the  stage  of  development  of  the  eblasakimab  products  at  the  time  of 
termination.

Development and License Agreement with Almirall

On  May  16,  2012,  we  entered  into  a  development  and  license  agreement  with  Almirall,  pursuant  to  which  we  obtained  an  exclusive, 
worldwide license to certain patents, know-how and other intellectual property controlled by Almirall to a DHODH inhibitor, LAS186323, 
which  we  refer  to  as  farudodstat.  The  licensed  field  covered  by  this  agreement  was  limited  to  the  treatment  or  prevention  of  rheumatoid 
arthritis, excluding any topical formulation.

On  December  21,  2015,  we  entered  into  an  amended  development  and  license  agreement  with  Almirall  which  replaced  the  previous 
agreement, further amended by an amendment agreement entered into on March 16, 2018. Under the agreement as so amended, we obtained 
from  Almirall  an  expanded  exclusive,  worldwide  license  to  develop,  manufacture  and  commercialize  farudodstat  products  for  all  human 
diseases,  excluding  topically-administered  products  embodying  the  compound  for  keratinocyte  hyperproliferative  disorders,  and  the  non-
melanoma skin cancers basal cell carcinoma, squamous cell carcinomas and Gorlin Syndrome (collectively, the KHD/NMSC products). We 
generally  have  the  right  to  sublicense  our  rights  under  the  agreement.  If  Almirall  wishes  to  use  a  third  party  to  develop  KHD/NMSC 
products, we have a right of first negotiation to obtain a license from Almirall to carry out those developments.

Under  the  amended  agreement,  we  are  generally  obligated  to  use  commercially  reasonable  efforts  to  develop  farudodstat  products  in 
accordance with the development plan, and to commercialize farudodstat products, either by ourselves or through sublicensees. We agreed 
not to develop or commercialize any competing product that has the same mechanism of action as farudodstat while the intellectual property 
licensed from Almirall remains in force or for ten years after the launch of farudodstat products on a country-by-country basis, whichever is 
longer.  In  addition,  we  granted  to  Almirall  the  right  to  use  certain  know-how  developed  by  or  on  behalf  of  us  for  Almirall’s  internal  and 
commercial programs for KHD/NMSC products, and Almirall granted us the right to use certain know-how developed by or on behalf of 
Almirall in the course of its programs for KHD/NMSC products in the field licensed to ASLAN.

In consideration of the rights granted to us under the amended agreement, we will be required to pay an aggregate of up to $30 million if 
certain development milestones are achieved and an aggregate of up to $50 million if certain regulatory milestones are achieved, in each case 
across different indications. If we commercialize any farudodstat products, we will be required to pay Almirall tiered royalties in the mid 
single-digit range on net sales of farudodstat products, subject to adjustments in certain circumstances. In the event we sublicense any of our
rights under the agreement relating to the farudodstat technology, we will be obligated to pay Almirall 10% of sublicensee income (excluding 
royalties) we may receive under such sublicenses.

Unless  earlier  terminated,  the  amended  agreement  continues  indefinitely.  Either  party  may  terminate  the  agreement  (i)  in  the  event  of  the 
other party’s material breach of the agreement that remains uncured for a specified period of time, (ii) if significant safety issues arise which 
make development or commercialization of the product unlawful or in violation of standard industry practices, (iii) if the other party becomes 
insolvent or (iv) if the continuation of the agreement is no longer commercially viable, as proven by us based on supporting objective data 
reasonably  acceptable  to  Almirall  and  us.  Almirall  may  terminate  the  agreement  (i)  if  we  fail  to  provide  evidence  of  having  used 
commercially reasonable efforts to pursue development or commercialization, (ii) if we challenge or assist third parties in challenging any
intellectual property rights licensed from Almirall under the amended agreement, (iii) if there is a general withdrawal or recall of farudodstat 
products  from  any  country,  on  a  product-by-product  and/or  country-by-country  basis  or  (iv)  upon  a  change  of  control  of  ASLAN  if  such
change of control could reasonably be expected to lead to an impairment to Almirall, subject to certain conditions. 

Collaboration and License Agreement with Kyungnam Biopharma

On March 11, 2019, we entered into a collaboration and license agreement with Kyungnam Biopharma (previously known as BioGenetics), 
pursuant to which we granted Kyungnam Biopharma the exclusive right under certain of our intellectual property and intellectual property 
that we have licensed from Almirall, to commercialize, and if agreed, manufacture, farudodstat for the treatment of all indications in South 
Korea,  excluding  topically  administered  products  for  the  treatment  of  keratinocyte  hyperproliferative  disorders  and  certain  non-melanoma 
skin cancers. Under the agreement, Kyungnam Biopharma will be responsible for obtaining initial and all subsequent regulatory approvals of 
farudodstat in South Korea, and we are obligated to use commercially reasonable efforts to provide information and cooperation as needed 
for these regulatory approvals. We may provide clinical drug supplies to Kyungnam Biopharma 

63

required  for  regulatory  filings  and  for  commercialization  of  products,  pursuant  to  a  separate  manufacturing  and  supply  agreement  to  be 
agreed between the parties.

In consideration of the rights granted to Kyungnam Biopharma under the agreement, we received an upfront payment of $1.0 million from 
Kyungnam Biopharma and are eligible to receive up to $8.0 million in certain one-time sales and development milestones, the thresholds for 
payment  of  such  sales  milestones  being  the  aggregate  of  sales  of  our  asset  varlitinib  (ASLAN001)  under  a  collaboration  and  license 
agreement with Kyungnam Biopharma entered into on February 27, 2019 and sales of farudodstat products. We are also eligible to receive 
tiered double-digit royalties on the aggregate net sales of farudodstat products, ranging from a percentage in the mid-teens up to a percentage 
within the mid-twenties. Kyungnam Biopharma is obligated to pay such royalties on a product-by-product basis until the expiration of the 
license  period  described  below.  Kyungnam  Biopharma  agreed  to  contribute  a  low  single-digit  percentage  of  certain  clinical  trial  costs  we 
incur in the clinical development of farudodstat products for the treatment of acute myeloid leukemia.

Under the agreement, we reserve the right to revoke the rights granted to Kyungnam Biopharma under this agreement at any time until the 
date of a certain regulatory milestone. If we exercise our right to revoke the rights granted to Kyungnam Biopharma, we will be obligated to 
pay  Kyungnam  Biopharma  a  sum  of  (i)  a  low  single-digit  multiple  of  certain  sums  paid  by  Kyungnam  Biopharma  under  this  license 
agreement  and,  if  we  have  agreed  upon  an  international  licensing  deal  for  farudodstat,  (ii)  a  low  single-digit  percentage  of  the  upfront 
payment, royalties and sales milestones received by us in any such deal.

During  the  license  period  and  for  one  year  thereafter,  neither  Kyungnam  Biopharma,  nor  any  of  its  affiliates,  will  participate  in  or  fund, 
directly or indirectly, the development, manufacture or commercialization of a product which competes with farudodstat. The license period 
commences on the effective date of the agreement and, unless terminated earlier pursuant to the terms of the agreement, expires on the tenth 
anniversary of first commercial sale, subject to an automatic renewal for a further year, which may be cancelled upon either party’s notice. 
Either party may terminate the agreement in the event of an uncured material breach by, or insolvency of, the other party, or in the event of a 
material  safety  risk  associated  with  the  product.  On  any  termination  of  the  agreement,  the  license  granted  to  Kyungnam  Biopharma  will 
terminate, subject to certain transitional provisions.

Intellectual Property

Patents

Our commercial success depends in part on our ability to identify, obtain and seek protection for our products, drug candidates and our core 
technologies employing a combination of patent rights, trade secrets, confidentiality agreements and contractual obligations, and to operate
without infringing, misappropriating or otherwise violating the proprietary rights of third parties. It is also important we prevent others from 
infringing, misappropriating or otherwise violating our proprietary or intellectual property rights.

Our  intellectual  property  strategy  is,  where  appropriate,  to  file  new  patent  applications  on  inventions,  including  improvements  to  existing 
products/candidates and processes to improve our competitive edge or to improve business opportunities. We continually assess and refine 
our intellectual property strategy to endeavor to ensure it is fit for purpose.

Our  strategy  requires  us  to  license  assets  from  third  parties  with  suitable  protection  and  to  identify  and  seek  patent  protection  for  our 
inventions,  when  possible.  This  process  is  expensive  and  time  consuming  and  we  may  not  be  able  to  file  and  prosecute  all  necessary  or 
desirable  patent  applications  at  a  reasonable  cost,  in  a  timely  manner  or  in  all  jurisdictions  where  protection  may  be  commercially 
advantageous, or we may financially not be able to protect our proprietary rights at all. Despite our efforts to protect our proprietary rights, 
unauthorized parties may be able to obtain and use information we regard as proprietary. Where possible, we seek to file in at least major 
commercial jurisdictions relevant to the product or technology, however, this is assessed on a case by case basis.

Licensing assets from third parties involves technical and scientific due diligence to assess the opportunity, the strength of the intellectual 
property protection for the asset and the ability to commercialize the asset. This due diligence is usually conducted over a relatively short 
period of time. It can be difficult to identify all the issues relevant to the assessment. Failure to identify all the relevant issues can impact 
negatively on the value of the asset.

The  issuance  of  a  patent  does  not  ensure  that  it  is  valid  or  enforceable.  Therefore,  even  if  we  are  issued  a  patent,  it  may  not  be  valid  or 
enforceable against third parties. Issued patents may be challenged, narrowed, invalidated or 

64

circumvented. In addition, court decisions may introduce uncertainty in the enforceability or scope of patents owned by pharmaceutical and 
biotechnology companies. Thus, any of our patents, including patents that we may rely on to protect our market for approved drugs, may be 
held invalid or unenforceable by a court of final jurisdiction.

Because patent applications in the United States, Europe and many other jurisdictions are typically not published until 18 months after filing, 
and because publications of discoveries in scientific literature lag behind actual discoveries, we cannot be certain that we were the first to 
make  the  inventions  claimed  in  our  issued  patents  or  pending  patent  applications,  or  that  we  were  the  first  to  file  for  protection  of  the 
inventions  set  forth  in  our  patents  or  patent  applications.  As  a  result,  we  may  not  be  able  to  obtain  or  maintain  protection  for  certain 
inventions.  Therefore,  the  enforceability  and  scope  of  our  patents  in  the  United  States,  Europe  and  in  many  other  jurisdictions  cannot  be 
predicted with certainty and, as a result, any patents that we own or license may not provide sufficient protection against competitors. We 
may not be able to obtain or maintain patent protection from our pending patent applications, from those we may file in the future, or from 
those  we  may  license  from  third  parties.  Moreover,  even  if  we  are  able  to  obtain  patent  protection,  such  patent  protection  may  be  of 
insufficient scope to achieve our business objectives.

In addition, the issuance of a patent does not give us the right to practice the patented invention. Third parties may have blocking patents that 
prevent marketing of our products or working our own technology. We endeavor to identify early third party patents and patent applications 
which may be blocking to a product or technology, to minimize this risk. However, relevant documents may be overlooked or missed, which 
may in turn impact on the freedom to commercialize the relevant asset.

The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions, including the United States, Europe, 
China and Japan, the basic patent term is 20 years from the earliest filing date of a non-provisional patent application. In the United States, 
Europe and Japan, patents relating to inventions are effective for 20 years, subject to the payment of renewal fees. Some jurisdictions, such as 
the  United  States,  Europe  and  Japan  provide  for  up  to  an  additional  five  years  patent  term  extension  for  therapeutic  products  that  require 
marketing approval. The requirements for this supplementary protection are set by the relevant authorities in the given jurisdiction. Products 
approved  before  the  expiry  of  the  basic  patent  term  may  benefit  from  such  a  patent  term  extension.  It  is  our  strategy  to  apply  for  such
supplementary protection, where possible.

In addition to patent protection, statutory provisions in the United States, Europe and other countries may provide a period of clinical data 
exclusivity which may be followed by an additional period of market exclusivity to compensate for the time required for regulatory approval 
of our drug products. Once the relevant criteria are satisfied, the protection applies automatically. The length of protection depends on the 
jurisdiction and may also depend on the type of therapy.

Third parties may seek to market “similar” versions of our approved products. Alternatively, third parties may seek approval to market their 
own products, similar or otherwise, competitive with our products. We may not be able to block the commercialization of these products, 
which may erode our commercial position in the marketplace.

If disputes over intellectual property and other rights that we have licensed or co-own prevent or impair our ability to maintain our current 
licensing or exclusivity arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product 
candidates. In addition, under certain of our collaboration agreements, our licensors may retain the right to grant non-exclusive licenses to the 
licensed patents and technology to other academic or research institutions for non-commercial research purposes.

Certain provisions in the agreements under which we currently license intellectual property or technology to and from third parties may be 
susceptible  to  multiple  interpretations.  The  resolution  of  any  contract  interpretation  disagreement  that  may  arise  could  narrow  what  we 
believe to be the scope of our rights to the relevant intellectual property or technology, increase what we believe to be our financial or other 
obligations  under  the  relevant  agreement  or  decrease  the  third  party’s  financial  or  other  obligations  under  the  relevant  agreement,  any  of 
which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Eblasakimab

On May 12, 2014, we entered into a license agreement with CSL, which was subsequently amended and restated on May 31, 2019, pursuant 
to which we obtained an exclusive, worldwide license to certain patents, know-how and other intellectual property owned or controlled by 
CSL related to CSL’s anti-IL13 receptor monoclonal antibody, CSL334, which we refer to as eblasakimab, and antigen binding fragments 
thereof, to develop, manufacture for clinical trials and commercialize eblasakimab for the treatment, diagnosis or prevention of diseases or 
conditions  in  humans.  Our  development  under  such  agreement  is  currently  focused  on  the  treatment  of  respiratory  and  inflammatory 
conditions, and in particular, atopic dermatitis.

With respect to eblasakimab, we exclusively licensed from CSL a family of patents which includes species (specific sequence) composition 
of matter patents, derived from WO2008/060813, filed October 19, 2007.

As of February 28, 2023, this family of patents included five issued patents in the United States and issued patents in a number of foreign 
countries and jurisdictions, including Australia, Canada, China, Europe, Hong Kong, India, and Japan. The scope of the claims may differ in 
the  various  countries.  The  issued  patents  in  this  family  are  expected  to  expire  in  October  2027,  subject  to  the  payment  of  renewal  fees, 
excluding any additional term for patent term adjustments or patent term extensions.

Owned by Us

We  are  co-applicants  together  with  CSL  on  a  number  of  pending  patents  mostly  relating  to  medical  uses  or  combination  therapies.  These 
include the following pending patent applications:

2023. If granted, this case will have a normal expiry of March 2042, subject to payment of renewal fees.

• WO2022/186773  is  a  published  PCT  application  filed  March  1,  2022.  It  relates  to  use  of  eblasakimab  in  atopic  dermatitis 
patients with high baseline levels of IgE. As of February 28, 2023, this case is in the international phase and due to enter the 
national/regional phase August/September 2023. If granted, this case will have a normal expiry of March 2042.

We  also  own  several  unpublished  PCT  applications  filed  in  2022  and  2023  relating,  variously,  to  a  form  of  eblasakimab,  formulations  of 
eblasakimab, and the use of eblasakimab in treatment. These cases are at an early stage and it is unclear what claims may be granted, if any.

Pursuant to the amended and restated license agreement with CSL entered into on May 31, 2019, any patents on intellectual property newly 
developed prior to the completion of the SAD study are to be in the joint names of ASLAN and CSL. All patents on intellectual property 
newly developed after the completion of the SAD study are to be in the sole name of ASLAN.

Farudodstat

Licensed from Almirall

On  May  16,  2012,  we  entered  into  a  development  and  license  agreement  with  Almirall,  pursuant  to  which  we  obtained  an  exclusive, 
worldwide license to certain patents, know-how and other intellectual property controlled by Almirall to a DHODH inhibitor, LAS186323, 
which we refer to as farudodstat. On December 21, 2015, we entered into an amended development and license agreement with Almirall 
which replaced the previous agreement. This was further amended by an amendment agreement entered into on March 16, 2018. Under the 
amended  agreement  as  so  amended,  we  obtained  from  Almirall  an  expanded  exclusive,  worldwide  license  to  develop,  manufacture  and 
commercialize  farudodstat  products  for  all  human  diseases  with  primary  focus  on  oncology  diseases,  excluding  topically-administered
products embodying the compound for keratinocyte hyperproliferative disorders, and the non-melanoma skin cancers basal cell carcinoma, 
squamous cell carcinomas and Gorlin Syndrome.

The basic compound protection for farudodstat is provided by the composition of matter family of patents derived from WO2008/077639 
filed December 21, 2007. As of February 28, 2023, this family of patents included patents issued in Argentina, Australia, Bolivia, Canada, 
China,  Chile,  Columbia,  Europe,  Hong  Kong,  India,  Indonesia,  Israel,  Japan,  Malaysia,  Mexico,  New  Zealand,  Nigeria,  Norway,  Peru, 
Philippines, Russia, Singapore, South Africa, South Korea, Taiwan, Ukraine, Uruguay, the United States (two patents) and Vietnam, and an 
allowed patent application in Ecuador. In addition, as of February 28, 2023, this family of patents included patent applications filed in Brazil, 
Egypt, Pakistan, Thailand, and Venezuela. The scope of the claims may differ in different countries. The normal expiration of this family of 
patents is December 2027, subject to the payment of renewal fees.

Owned by Us

We are the applicant on a number of pending patents mostly relating to medical uses or combination therapies. These include the following 
pending patent applications:

• WO2018/160138 filed March 1, 2018 relates to use of farudodstat in treatment of hematological cancers. As of February 28, 
2023,  this  family  of  patents  includes  patent  applications  filed  in  China,  Europe,  Japan,  and  the  United  States  (2  cases).  The 
normal expiration of this family of patents is March 2038, subject to the payment of renewal fees.

• WO2022/045984 is a published PCT application filed August 30, 2021, related to treatment of viral infection with farudodstat.

If granted, the normal expiry for this case will be August 2041, subject to payment of renewal fees.

• WO2022/081095  is  a  published  PCT  application  filed  October  15,  2021,  related  to  treatment  of  autoimmune  disease  with 

farudodstat. If granted, the normal expiry for this case will be October 2041, subject to payment of renewal fees.

We  also  own  unpublished  PCT  applications,  one  filed  in  April  2022  related  to  the  use  of  farudodstat  in  treatment,  and  another  filed  in 
February 2023 related to a form of farudodstat. These cases are at an early stage and it is unclear what claims may be granted, if any. 

Trade Secrets

In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain 
our competitive position. However, trade secrets and know-how can be difficult to protect. We seek to protect our proprietary information, in 
part,  by  executing  confidentiality  agreements  with  our  partners,  collaborators,  scientific  advisors,  employees,  consultants  and  other  third 
parties, and invention assignment agreements which are included in the engagement and employment contracts we have with our consultants 
and  employees.  The  confidentiality  agreements  we  enter  into  are  designed  to  protect  our  proprietary  information  and  the  agreements  or 
clauses  requiring  assignment  of  inventions  to  us  are  designed  to  grant  us  ownership  of  technologies  that  are  developed  through  our 
relationship with the respective counterparty. We cannot guarantee that we have entered into such agreements with each party that may have 
or have had access to our trade secrets or proprietary technology and processes or that these agreements will afford us adequate protection of 
our  intellectual  property  and  proprietary  information  rights.  If  any  of  the  partners,  collaborators,  scientific  advisors,  employees  and 
consultants  who  are  parties  to  these  agreements  breaches  or  violates  the  terms  of  any  of  these  agreements  or  otherwise  discloses  our 
proprietary information, 

67

we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets as a result. If we are unable to 
maintain the confidentiality of our trade secrets, our business and competitive position may be harmed.

Trademarks and Domain Names

We  conduct  our  business  using  the  trademark  “ASLAN,”  “ASLAN  PHARMACEUTICALS”  and  our  lion  logo,  as  well  as  domain  names 
incorporating  either  or  both  of  these  trademarks.  “ASLAN”  has  been  registered  as  a  trademark  in  USA,  Japan  and  Singapore,  and  is  the 
subject  of  pending  trademark  applications  in  EU  and  China.  “ASLAN  PHARMACEUTICALS”  and  our  lion  logo  has  been  registered  in 
Singapore.  We  have  a  portfolio  of  16  domain  names,  which  includes:  aslanpharma.com,  aslanpharma.com.sg,  aslanpharma.com.tw, 
aslanpharma.asia, aslanpharma.org, and aslanpharma.biz.

Government Regulation

The U.S. FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements 
upon  the  clinical  development,  manufacture  and  marketing  of  pharmaceutical  products.  These  agencies  and  other  federal,  state  and  local 
entities  regulate  research  and  development  activities  and  the  testing,  manufacture,  quality  control,  safety,  effectiveness,  labeling,  storage, 
packaging, recordkeeping, tracking, approval, import, export, distribution, advertising and promotion of our products.

U.S. Government Regulation of Drug and Biologic Products

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (FFDCA) and biologics such as eblasakimab 
additionally under the Public Health Service Act, as well as the implementing regulations for these laws. The process of obtaining regulatory 
approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations requires the expenditure of 
substantial time and financial resources. 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 to a variety of administrative or judicial sanctions, such as the FDA’s 
refusal  to  approve  pending  New  Drug  Applications  (NDAs)  or  Biologics  License  Applications  (BLAs),  withdrawal  of  an  approval, 
imposition  of  a  clinical  hold,  issuance  of  warning  letters,  product  recalls,  product  seizures,  total  or  partial  suspension  of  production  or 
distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before product candidates may be marketed in the United States generally involves the following:

•

•

•

•

•

•

•

•

•

•

Nonclinical laboratory and animal tests that must be conducted in accordance with GLP;

Submission of an IND, which must become effective before clinical trials may begin;

Approval  by  an  independent  institutional  review  board  (IRB)  for  each  clinical  site  or  centrally  before  each  trial  may  be 
initiated;

Adequate  and  well-controlled  human  clinical  trials  to  establish  the  safety  and  efficacy  of  the  proposed  drug  product  for  its 
intended use or the safety, purity and potency of a biologic for its intended use, performed in accordance with current clinical 
practices (cGCP);

Submission to the FDA of an NDA or BLA and payment of user fees;

Satisfactory completion of a FDA advisory committee review, if applicable;

Pre-Approval inspection of manufacturing facilities for their compliance with cGMP;

Satisfactory completion of FDA audits of clinical trial sites to assure compliance with cGCP and the integrity of the clinical 
data;

FDA approval of an NDA or BLA to permit commercial marketing for particular indications for use; and

Compliance  with  any  post-approval  requirements,  including  the  potential  requirement  to  implement  a  Risk  Evaluation  and 
Mitigation Strategy (REMS) and the potential requirement to conduct post-approval studies.

The testing and approval process requires substantial time, effort and financial resources. Preclinical studies include laboratory evaluation of 
drug substance chemistry, pharmacology, toxicity and drug product formulation, as well as 

68

animal studies to assess potential safety and efficacy. Prior to commencing the first clinical trial with a product candidate, we must submit the 
results of the preclinical tests and preclinical literature, together with manufacturing information, analytical data and any available clinical 
data or literature, among other things, to the FDA as part of an IND. Some preclinical studies may continue even after the IND is submitted. 
The  IND  automatically  becomes  effective  30  days  after  receipt  by  the  FDA,  unless  the  FDA,  within  the  30-day  time  period,  raises  safety 
concerns or questions about the conduct of the clinical trial by imposing a clinical hold. In such a case, the IND sponsor and the FDA must 
resolve any outstanding concerns before the clinical trial can begin. Submission of an IND may not result in FDA authorization to commence 
a clinical trial.

Clinical trials involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in 
accordance with cGCP requirements. A separate submission to the existing IND must be made for each successive clinical trial conducted 
during product development, as well as amendments to previously submitted clinical trials. Further, an independent IRB for each study site 
proposing  to  conduct  the  clinical  trial  must  review  and  approve  the  plan  for  any  clinical  trial,  its  informed  consent  form  and  other 
communications to study subjects before the clinical trial commences at that site. The IRB must continue to oversee the clinical trial while it 
is being conducted, including any changes to the study plans.

Regulatory authorities, an IRB or the sponsor may suspend or discontinue a clinical trial at any time on various grounds, including a finding 
that the subjects are being exposed to an unacceptable health risk, the clinical trial is not being conducted in accordance with the FDA’s or the 
IRB’s requirements, if the drug has been associated with unexpected serious harm to subjects, or based on evolving business objectives or 
competitive climate. Some studies also include a data safety monitoring board, which receives special access to unblinded data during the 
clinical trial and may advise us to halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, 
such as no demonstration of efficacy.

In general, for purposes of NDA or BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap.

Phase 1—Studies are initially conducted to test the product candidate for safety, dosage tolerance, structure-activity relationships, mechanism 
of action, absorption, metabolism, distribution and excretion in healthy volunteers or subjects with the target disease or condition. If possible, 
Phase 1 trials may also be used to gain an initial indication of product effectiveness.

Phase 2—Controlled studies are conducted with groups of subjects with a specified disease or condition to provide enough data to evaluate 
the  preliminary  efficacy,  optimal  dosages  and  dosing  schedule  and  expanded  evidence  of  safety.  Multiple  Phase  2  clinical  trials  may  be 
conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

Phase 3—These clinical trials are undertaken in larger subject populations to provide statistically significant evidence of clinical efficacy and 
to further test for safety in an expanded subject population at multiple clinical trial sites. These clinical trials are intended to establish the 
overall  risk/benefit  ratio  of  the  product  and  provide  an  adequate  basis  for  product  labeling.  These  trials  may  be  done  globally  to  support 
global  registrations  so  long  as  the  global  sites  are  also  representative  of  the  U.S.  population  and  the  conduct  of  the  study  at  global  sites 
comports with FDA regulations and guidance, such as compliance with cGCP.

The FDA may require, or companies may pursue, additional clinical trials after a product is approved. These so-called Phase 4 studies may 
be made a condition to be satisfied after approval. The results of Phase 4 studies can confirm the effectiveness of a product candidate and can 
provide important safety information.

Clinical trials must be conducted under the supervision of qualified investigators in accordance with cGCP requirements, which includes the 
requirements that all research subjects provide their informed consent in writing for their participation in any clinical trial, and the review and 
approval  of  the  study  by  an  IRB.  Investigators  must  also  provide  information  to  the  clinical  trial  sponsors  to  allow  the  sponsors  to  make 
specified financial disclosures to the FDA. Clinical trials are conducted under protocols detailing, among other things, the objectives of the 
trial, the trial procedures, the parameters to be used in monitoring safety and the efficacy criteria to be evaluated and a statistical analysis 
plan. Information about some clinical trials, including a description of the trial and trial results, must be submitted within specific timeframes 
to the National Institutes of Health (NIH) for public dissemination on their ClinicalTrials.gov website.

69

The manufacture of investigational drugs for the conduct of human clinical trials is subject to cGMP requirements. Investigational drugs and 
active  pharmaceutical  ingredients  imported  into  the  United  States  are  also  subject  to  regulation  by  the  FDA  relating  to  their  labeling  and 
distribution.  Further,  the  export  of  investigational  drug  products  outside  of  the  United  States  is  subject  to  regulatory  requirements  of  the 
receiving country as well as U.S. export requirements under the FFDCA. Progress reports detailing the results of the clinical trials must be 
submitted at least annually to the FDA and the IRB and more frequently if serious adverse events occur.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the 
chemistry  and  physical  characteristics  of  the  product  candidate  as  well  as  finalize  a  process  for  manufacturing  the  product  in  commercial 
quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of 
the product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final product. 
Additionally,  appropriate  packaging  must  be  selected  and  tested,  and  stability  studies  must  be  conducted  to  demonstrate  that  the  product 
candidate does not undergo unacceptable deterioration over its shelf life.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition (generally 
meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that 
the cost of developing and making a drug available in the United States for treatment of the disease or condition will be recovered from sales 
of  the  product).  Orphan  product  designation  must  be  requested  before  submitting  an  NDA  or  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.

If a product with orphan status receives the first FDA approval for the disease or condition for which it has such designation, the product is 
entitled to orphan product exclusivity, meaning that the FDA may not approve any other applications to market the same drug for the same 
indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity or 
if the party holding the exclusivity fails to assure the availability of sufficient quantities of the drug to meet the needs of patients with the 
disease  or  condition  for  which  the  drug  was  designated.  Competitors,  however,  may  receive  approval  of  different  products  for  the  same 
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 medicinal product status in the European Union has similar, but not identical, benefits. For example, 
the European Union grants ten years of product exclusivity for orphan medicinal products.

Special FDA Expedited Review and Approval Programs

The FDA has various programs, including fast track designation, breakthrough therapy designation, accelerated approval, and priority review, 
which are intended to expedite or simplify the process for the development and FDA review of drugs that are intended for the treatment of 
serious  or  life  threatening  diseases  or  conditions  and  demonstrate  the  potential  to  address  unmet  medical  needs.  The  purpose  of  these 
programs is to provide important new drugs to patients earlier than under standard FDA review procedures.

Under  the  fast  track  program,  the  sponsor  of  a  new  drug  candidate  may  request  that  FDA  designate  the  drug  candidate  for  a  specific 
indication as a fast track drug concurrent with, or after, the filing of the IND for the drug candidate. To be eligible for a fast track designation, 
the FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or life threatening disease or condition 
and demonstrates the potential to address an unmet medical need. The FDA will determine that a product will fill an unmet medical need if it 
will provide a therapy where none exists or provide a therapy that may be potentially superior to existing therapy based on efficacy or safety 
factors. Fast track designation provides additional opportunities for interaction with the FDA’s review team and may allow for rolling review 
of  NDA  or  BLA  components  before  the  completed  application  is  submitted,  if  the  sponsor  provides  a  schedule  for  the  submission  of  the 
sections  of  the  application,  the  FDA  agrees  to  accept  sections  and  determines  that  the  schedule  is  acceptable,  and  the  sponsor  pays  any 
required user fees upon submission of the first section of the application. However, FDA’s time period goal for reviewing an application does 
not begin until the last section of the application is submitted. The FDA may decide to rescind the fast track designation if it determines that 
the qualifying criteria no longer apply.

In addition, a sponsor can request breakthrough therapy designation for a drug if it is intended, alone or in combination with one or more 
other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence 

70

indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such 
as substantial treatment effects observed early in clinical development. Drugs designated as breakthrough therapies are eligible for intensive
guidance from FDA on an efficient drug development program, organizational commitment to the development and review of the product 
including involvement of senior managers, and, like fast track products, are also eligible for rolling review of the NDA. Both fast track and 
breakthrough therapy products are also eligible for accelerated approval and/or priority review, if relevant criteria are met.

Under  the  FDA’s  accelerated  approval  regulations,  the  FDA  may  approve  a  drug  for  a  serious  or  life  threatening  illness  that  provides 
meaningful therapeutic benefit to patients over existing treatments based upon a surrogate endpoint that is reasonably likely to predict clinical 
benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an 
effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition 
and  the  availability  or  lack  of  alternative  treatments.  A  drug  candidate  approved  on  this  basis  is  subject  to  rigorous  post  marketing 
compliance requirements, including the completion of Phase 4 or post approval clinical trials to confirm the effect on the clinical endpoint. 
Failure to conduct required post approval studies, or confirm a clinical benefit during post marketing studies, will allow FDA to withdraw the 
drug from the market on an expedited basis. All promotional materials for drug candidates approved under accelerated approval regulations 
are subject to prior review by FDA.

Once an NDA or BLA is submitted for a product intended to treat a serious condition, the FDA may assign a priority review designation if 
FDA determines that the product, if approved, would provide a significant improvement in safety or effectiveness. A priority review means 
that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current Prescription 
Drug User Fee Act (PDUFA) guidelines. Under the current PDUFA agreement, these six and ten month review periods are measured from 
the 60-day filing date rather than the receipt date for applications for new molecular entities, which typically adds approximately two months 
to the timeline for review from the date of submission. Most products that are eligible for fast track breakthrough therapy designation are also 
likely to be considered appropriate to receive a priority review.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for 
qualification  or  decide  that  the  time  period  for  FDA  review  or  approval  will  not  be  shortened.  In  addition,  the  manufacturer  of  an 
investigational drug for a serious or life threatening disease is required to make available, such as by posting on its website, its policy on 
responding to requests for expanded access. Furthermore, fast track designation, breakthrough therapy designation, accelerated approval and 
priority review do not change the standards for approval and may not ultimately expedite the development or approval process.

NDA or BLA Submission and Review by the FDA

Assuming  successful  completion  of  the  required  clinical  and  preclinical  testing,  among  other  items,  the  results  of  product  development, 
including chemistry, manufacture and controls, nonclinical studies and clinical trials are submitted to the FDA, along with proposed labeling, 
as part of an NDA or BLA. The submission of an NDA or BLA requires payment of a substantial user fee to the FDA. These user fees must 
be filed at the time of the first submission of the application, even if the application is being submitted on a rolling basis. Fee waivers or 
reductions are available in some circumstances. One basis for a waiver of the application user fee is if the applicant employs fewer than 500 
employees,  including  employees  of  affiliates,  the  applicant  does  not  have  an  approved  marketing  application  for  a  product  that  has  been 
introduced or delivered for introduction into interstate commerce, and the applicant, including its affiliates, is submitting its first marketing 
application.

In addition, under the Pediatric Research Equity Act, an NDA or BLA or supplement thereto for a new active ingredient, indication, dosage 
form,  dosage  regimen  or  route  of  administration  must  contain  data  that  are  adequate  to  assess  the  safety  and  efficacy  of  the  drug  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, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after 
approval of the product for use in adults or full or partial waivers from the pediatric data requirements.

71

The FDA must refer applications for drugs that contain active ingredients, including any ester or salt of the active ingredients, which have not 
previously been approved by the FDA to an advisory committee or provide in an action letter a summary of the reasons for not referring it to 
an  advisory  committee.  The  FDA  may  also  refer  drugs  which  present  difficult  questions  of  safety,  purity  or  potency  to  an  advisory 
committee.  An  advisory  committee  is  typically  a  panel  that  includes  clinicians  and  other  experts  who  review,  evaluate  and  make  a 
recommendation  as  to  whether  the  application  should  be  approved  and  under  what  conditions.  The  FDA  is  not  bound  by  the 
recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

The FDA reviews applications to determine, among other things, whether a product is safe and effective for its intended use and whether the 
manufacturing controls are adequate to assure and preserve the product’s identity, strength, quality and purity. Before approving an NDA or 
BLA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it 
determines that the manufacturing processes and facilities, including contract manufacturers and subcontracts, are in compliance with cGMP 
requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an 
NDA or BLA, the FDA will typically inspect one or more clinical trial sites to assure compliance with cGCP.

Once the FDA receives an application, it has 60 days to review and determine if it is substantially complete to permit a substantive review, 
before it accepts the application for filing. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA’s review 
times may differ based on whether the application is a standard review or priority review application. The FDA may give a priority review 
designation to drugs that are intended to treat serious conditions and provide significant improvements in the safety or effectiveness of the 
treatment, diagnosis, or prevention of serious conditions. Under the goals and policies agreed to by the FDA under the PDUFA, the FDA has 
set the review goal of 10 months from the 60-day filing date to complete its initial review of a standard NDA or BLA for a new molecular 
entity (NME) and make a decision on the application. For non-NME standard applications, the FDA has set the review goal of 10 months 
from the submission date to complete its initial review and to make a decision on the application. For priority review applications, the FDA 
has set the review goal of reviewing NME NDAs within six months of the 60-day filing date and non-NME applications within six months of 
the submission date. Such deadlines are referred to as the PDUFA date. The PDUFA date is only a goal and the FDA does not always meet its 
PDUFA dates. The review process and the PDUFA date may also be extended if the FDA requests or the NDA sponsor otherwise provides 
additional information or clarification regarding the submission.

Once the FDA’s review of the application is complete, the FDA will issue either a Complete Response Letter (CRL) or approval letter. A 
CRL indicates that the review cycle of the application is complete and the application is not ready for approval. A CRL generally contains a 
statement of specific conditions that must be met in order to secure final approval of the NDA or BLA and may require additional clinical or 
preclinical testing, or other information or analyses in order for the FDA to reconsider the application. Even with the submission of additional 
information,  the  FDA  ultimately  may  decide  that  the  application  does  not  satisfy  the  regulatory  criteria  for  approval.  If  and  when  those 
conditions  have  been  met  to  the  FDA’s  satisfaction,  the  FDA  may  issue  an  approval  letter.  An  approval  letter  authorizes  commercial 
marketing of the drug with specific prescribing information for specific indications. The FDA may delay or refuse approval of an NDA if 
applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance
to  monitor  safety  or  efficacy  of  a  product,  or  impose  other  conditions,  including  distribution  restrictions  or  other  risk  management 
mechanisms.  For  example,  the  FDA  may  require  a  REMS  as  a  condition  of  approval  or  following  approval  to  mitigate  any  identified  or 
suspected serious risks and ensure safe use of the drug. The FDA may prevent or limit further marketing of a product, or impose additional 
post-marketing requirements, based on the results of post-marketing studies or surveillance programs. After approval, some types of changes 
to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing 
requirements,  FDA  notification  and  FDA  review  and  approval.  Further,  should  new  safety  information  arise,  additional  testing,  product 
labeling or FDA notification may be required.

If  regulatory  approval  of  a  product  is  granted,  such  approval  may  entail  limitations  on  the  indicated  uses  for  which  such  product  may  be 
marketed or may include contraindications, warnings or precautions in the product labeling, which has resulted in a black box warning. The 
FDA also may not approve the inclusion of labeling claims necessary for successful marketing. Once approved, the FDA may withdraw the 
product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if problems occur after the product 
reaches the marketplace. In addition, the FDA may require Phase 4 post-marketing studies to monitor the effect of approved products, and 
may limit further marketing of the product based on the results of these post-marketing studies.

Post-Approval Requirements

Any  products  manufactured  or  distributed  by  us  pursuant  to  FDA  approvals  are  subject  to  continuing  regulation  by  the  FDA,  including 
manufacturing, periodic reporting, product sampling and distribution, advertising, promotion, drug shortage reporting, compliance with any 
post-approval requirements imposed as a conditional of approval such as Phase 4 clinical trials, REMS and surveillance, recordkeeping and 
reporting requirements, including adverse experiences.

After  approval,  most  changes  to  the  approved  product,  such  as  adding  new  indications  or  other  labeling  claims  are  subject  to  prior  FDA 
review and approval. There also are continuing, annual user fee requirements for any approved products and the establishments at which such 
products are manufactured, as well as new application fees for supplemental applications with clinical data. Drug manufacturers and their 
subcontractors are required to register their establishments with the FDA and certain state agencies and to list their drug products, and are 
subject  to  periodic  announced  and  unannounced  inspections  by  the  FDA  and  these  state  agencies  for  compliance  with  cGMP  and  other 
requirements, which impose procedural and documentation requirements upon us and our third-party manufacturers.

Changes  to  the  manufacturing  process  are  strictly  regulated  and  often  require  prior  FDA  approval  before  being  implemented,  or  FDA 
notification.  FDA  regulations  also  require  investigation  and  correction  of  any  deviations  from  cGMP  and  specifications,  and  impose 
reporting  and  documentation  requirements  upon  the  sponsor  and  any  third-party  manufacturers  that  the  sponsor  may  decide  to  use. 
Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP 
compliance.

Later  discovery  of  previously  unknown  problems  with  a  product,  including  AEs  of  unanticipated  severity  or  frequency,  or  with 
manufacturing  processes,  or  failure  to  comply  with  regulatory  requirements,  may  result  in  withdrawal  of  marketing  approval,  mandatory 
revisions to the approved labeling to add new safety information or other limitations, imposition of post-market studies or clinical trials to 
assess new safety risks, or imposition of distribution or other restrictions under a REMS program, among other consequences.

The FDA closely regulates the marketing and promotion of drugs. A company can make only those claims relating to safety and efficacy, 
purity and potency that are approved by the FDA. Physicians, in their independent professional medical judgement, may prescribe legally 
available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. 
We, however, are prohibited from marketing or promoting drugs for uses outside of the approved labeling.

In  addition,  the  Drug  Supply  Chain  Security  Act  imposes  obligations  on  manufacturers  of  pharmaceutical  products  related  to  product 
tracking and tracing.

Failure  to  comply  with  any  of  the  FDA’s  requirements  could  result  in  significant  adverse  enforcement  actions.  These  include  a  variety  of 
administrative  or  judicial  sanctions,  such  as  refusal  to  approve  pending  applications,  license  suspension  or  revocation,  withdrawal  of  an 
approval,  imposition  of  a  clinical  hold  or  termination  of  clinical  trials,  warning  letters,  untitled  letters,  cyber  letters,  modification  of 
promotional  materials  or  labeling,  product  recalls,  product  seizures  or  detentions,  refusal  to  allow  imports  or  exports,  total  or  partial 
suspension  of  production  or  distribution,  debarment,  injunctions,  fines,  consent  decrees,  corporate  integrity  agreements,  refusals  of 
government  contracts  and  new  orders  under  existing  contracts,  exclusion  from  participation  in  federal  and  state  healthcare  programs, 
restitution, disgorgement or civil or criminal penalties, including fines and imprisonment. It is also possible that failure to comply with the 
FDA’s  requirements  relating  to  the  promotion  of  prescription  drugs  may  lead  to  investigations  alleging  violations  of  federal  and  state 
healthcare fraud and abuse and other laws, as well as state consumer protection laws. Any of these sanctions could result in adverse publicity, 
among other adverse consequences.

Other U.S. Healthcare Laws and Regulations

Healthcare providers and third-party payors play a primary role in the recommendation and use of medical products and drug formulations 
that  are  granted  marketing  approval.  Arrangements  with  third-party  payors,  existing  or  potential  customers  and  referral  sources,  including 
healthcare  providers,  are  subject  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations,  and  these  laws  and 
regulations may constrain the business or financial arrangements and relationships through which manufacturers conduct clinical research, 
market,  sell  and  distribute  the  products  for  which  they  obtain  marketing  approval.  Such  restrictions  under  applicable  federal  and  state 
healthcare laws and regulations include the following:

•

•

•

•

•

The  U.S.  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  and  entities  from  knowingly  and  willfully 
soliciting, receiving, offering or paying remuneration, directly or indirectly, in cash or kind, in exchange for, or to induce, either 
the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be 
made  under  federal  healthcare  programs  such  as  the  Medicare  and  Medicaid  programs.  This  statute  has  been  interpreted  to 
apply  to  arrangements  between  pharmaceutical  manufacturers,  on  the  one  hand,  and  prescribers,  purchasers  and  formulary 
managers, among others, on the other hand. The Patient Protection and Affordable Care Act, as amended by the Health Care 
and  Education  Reconciliation  Act  of  2010  (PPACA),  amended  the  intent  requirement  of  the  U.S.  Anti-Kickback  Statute.  A 
person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to commit a 
violation.  There  are  a  number  of  statutory  exceptions  and  regulatory  safe  harbors  protecting  some  common  activities  from 
prosecution;

The federal false claims laws, including the False Claims Act (FCA) and civil monetary penalties laws which prohibit, among 
other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, 
Medicaid or other third-party payors that are false or fraudulent, or making a false statement to avoid, decrease, or conceal an 
obligation  to  pay  money  to  the  federal  government.  As  a  result  of  a  modification  made  by  the  Fraud  Enforcement  and 
Recovery Act of 2009, a claim includes “any request or demand” for money or property presented to the U.S. government. In 
addition, manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors 
if they are deemed to “cause” the submission of false or fraudulent claims. The FCA also permits a private individual acting as 
a  “whistleblower”  to  bring  actions  on  behalf  of  the  federal  government  alleging  violations  of  the  FCA  and  to  share  in  any 
monetary recovery. Government enforcement agencies and private whistleblowers have investigated pharmaceutical companies 
for  or  asserted  liability  under  the  FCA  for  a  variety  of  alleged  promotional  and  marketing  activities,  such  as  providing  free 
product to customers with the expectation that the customers would bill federal programs for the product; providing consulting
fees  and  other  benefits  to  physicians  to  induce  them  to  prescribe  products;  engaging  in  promotion  for  “off-label”  uses;  and 
submitting inflated best price information to the Medicaid Rebate Program. In addition, the PPACA codified case law that a 
claim including items or services resulting from a violation of the U.S. Anti-Kickback Statute constitutes a false or fraudulent 
claim for purposes of the FCA;

The  Health  Insurance  Portability  and  Accountability  Act  of  1996  (HIPAA)  prohibits,  among  other  actions,  knowingly  and 
willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party 
payors,  knowingly  and  willfully  embezzling  or  stealing  from  a  healthcare  benefit  program,  willfully  obstructing  a  criminal 
investigation  of  a  healthcare  offense,  and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a  material  fact  or 
making  any  materially  false,  fictitious  or  fraudulent  statement  in  connection  with  the  delivery  of  or  payment  for  healthcare 
benefits, items or services;

The federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical 
supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific 
exceptions, to report annually to the Centers for Medicare & Medicaid Services (CMS), information related to payments and 
other  transfers  of  value  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors),  other 
healthcare  professionals  (such  as  physicians  assistants  and  nurse  practitioners)  and  teaching  hospitals,  and  ownership  and 
investment interests held by physicians and their immediate family members;

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  (HITECH),  and  their 
respective implementing regulations, imposes, among other things, specified requirements relating to the security, privacy and 
transmission of individually identifiable health information held by entities subject to HIPAA, such as health plans, health care 
clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates, persons or 
entities that create, use, maintain or disclose individually identifiable health information on behalf of covered 

74

entities, as well as their covered subcontractors. HITECH also created new tiers of civil monetary penalties, amended HIPAA 
to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to
file civil actions for damages or injunctions in U.S. federal courts to enforce the federal HIPAA laws and seek attorneys’ fees 
and costs associated with pursuing federal civil actions; and

•

State and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may 
apply  to  items  or  services  reimbursed  by  any  third-party  payor,  including  commercial  insurers;  state  laws  that  require 
pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant 
compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare 
providers  and  other  potential  referral  sources;  state  laws  that  require  drug  manufacturers  to  report  information  related  to 
payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; state and local 
laws that require the registration of pharmaceutical sales representatives; and state laws governing the privacy and security of 
health information in certain circumstances, many of which differ from each other in significant ways and may not have the 
same effect, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that
certain business activities can be subject to challenge under one or more of such laws. In addition, recent health care reform legislation has 
strengthened these laws.

Violation  of  the  laws  described  above  or  any  other  governmental  laws  and  regulations  may  result  in  significant  civil,  criminal  and 
administrative penalties, damages, fines, the curtailment or restructuring of operations, the exclusion from participation in federal and state 
healthcare  programs,  disgorgement,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  imprisonment,  and 
additional reporting requirements and oversight if a manufacturer becomes subject to a corporate integrity agreement or similar agreement to 
resolve  allegations  of  non-compliance  with  these  laws.  Furthermore,  efforts  to  ensure  that  business  activities  and  business  arrangements 
comply with applicable healthcare laws and regulations can be costly for manufacturers of branded prescription products.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any products, for which we may obtain regulatory approval, and 
the procedures utilizing such products. In the United States, sales of any product candidates for which regulatory approval for commercial 
sale  is  obtained  will  depend  in  part  on  the  availability  of  coverage  and  adequate  reimbursement  from  third-party  payors  for  the  approved 
products, and procedures which utilize such products. Third-party payors include government authorities and health programs in the United 
States such as Medicare and Medicaid, managed care providers, private health insurers and other organizations. These third-party payors are 
increasingly reducing reimbursements for medical products and services. The process for determining whether a payor will provide coverage 
for a product, or procedures which utilizes such product, may be separate from the process for setting the reimbursement rate that the payor 
will pay for the product, or procedures which utilize such product. Third-party payors may limit coverage to specific products on an approved 
list, or formulary, which might not include all of U.S. FDA-approved products for a particular indication.

Additionally,  the  containment  of  healthcare  costs  has  become  a  priority  of  federal  and  state  governments.  The  U.S.  government,  state 
legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, 
restrictions on coverage and reimbursement and requirements for substitution of less expensive products and procedures. Adoption of price 
controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could 
further limit our net revenue and results.

A  payor’s  decision  to  provide  coverage  for  a  product,  or  procedures  which  utilize  such  product,  does  not  imply  that  an  adequate 
reimbursement  rate  will  be  approved.  Further,  coverage  and  reimbursement  for  products,  and  procedure  which  utilize  such  products,  can 
differ significantly from payor to payor. Private payors may follow CMS, but have their own methods and approval processes for determining 
reimbursement for new medicines, and the procedures that utilize new medicines. As a result, the coverage determination process is often a 
time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor 
separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

75

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and 
services, in addition to their safety and efficacy. In order to obtain coverage and reimbursement for any product that might be approved for 
sale,  or  any  procedure  which  utilizes  such  product,  it  may  be  necessary  to  conduct  expensive  pharmacoeconomic  studies  in  order  to 
demonstrate the medical necessity and cost-effectiveness of the products, and procedures which utilize such products, in addition to the costs 
required to obtain regulatory approvals. If third-party payors do not consider a product, or procedures which utilize such product, to be cost-
effective compared to other available therapies, they may not cover the product, or procedures which utilize such product, after approval as a 
benefit under their plans or, if they do, the level of payment may not be sufficient to allow a company to sell its products at a profit.

The marketability of any product candidates for which we or our collaborators receive regulatory approval for commercial sale may suffer if 
the government and third-party payors fail to provide adequate coverage and reimbursement for the product, or any procedure which utilizes 
such product. In addition, emphasis on managed care in the United States has increased and we expect will continue to increase the pressure 
on medical products and services pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable 
coverage and reimbursement status is attained for one or more products for which we or our collaborators receive regulatory approval, less 
favorable coverage policies and reimbursement rates may be implemented in the future.

In the European Union, 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. Some countries may require the completion of additional studies that compare 
the  cost-effectiveness  of  a  particular  product  candidate  to  currently  available  therapies.  European  Union  Member  States  may  approve  a 
specific  price  for  a  product  or  it  may  instead  adopt  a  system  of  direct  or  indirect  controls  on  the  profitability  of  the  company  placing  the 
product on the market. Other member states allow companies to fix their own prices for products, but monitor and control company profits. 
The downward pressure on health care costs has become intense. As a result, increasingly high barriers are being erected to the entry of new 
products. In addition, in some countries, cross-border imports from low-priced markets exert competitive pressure that may reduce pricing 
within  a  country.  Any  country  that  has  price  controls  or  reimbursement  limitations  may  not  allow  favorable  reimbursement  and  pricing 
arrangements.

Health Reform

The  United  States  and  some  foreign  jurisdictions  are  considering  or  have  enacted  a  number  of  reform  proposals  to  change  the  healthcare 
system.  There  is  significant  interest  in  promoting  changes  in  healthcare  systems  with  the  stated  goals  of  containing  healthcare  costs, 
improving quality or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has 
been  significantly  affected  by  federal  and  state  legislative  initiatives,  including  those  designed  to  limit  the  pricing,  coverage,  and 
reimbursement  of  pharmaceutical  and  biopharmaceutical  products  as  well  as  the  procedures  which  utilize  such  products,  especially  under 
government-funded health care programs, and increased governmental control of health care costs.

By  way  of  example,  in  March  2010,  the  PPACA  was  signed  into  law,  which  is  intended  to  broaden  access  to  health  insurance,  reduce  or 
constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and 
health  insurance  industries,  impose  taxes  and  fees  on  the  healthcare  industry  and  impose  additional  health  policy  reforms.  Among  the 
provisions of the PPACA of importance to our business are:

•

•

•

An  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  specified  branded  prescription  drugs  and  biologic 
agents, apportioned among these entities according to their market share in certain government healthcare programs;

An increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 
13.0% of the average manufacturer price for branded and generic drugs, respectively;

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;

76

•

•

•

•

•

•

Expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to 
certain individuals with income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s 
Medicaid rebate liability;

Expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;

A  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct  comparative  clinical 
effectiveness research, along with funding for such research;

A  new  Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers  must  agree  to  offer  50%  (and  70%  as  of 
January 1, 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their 
coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D;

Establishment  of  a  Center  for  Medicare  and  Medicaid  Innovation  at  CMS  to  test  innovative  payment  and  service  delivery 
models to lower Medicare and Medicaid spending, potentially including prescription drug spending; and

A licensure framework for follow on biologic products.

There have been executive, judicial and Congressional challenges to certain aspects of the PPACA. For example, on June 17, 2021, the U.S. 
Supreme Court dismissed a challenge on procedural grounds that argued the PPACA is unconstitutional in its entirety because the “individual 
mandate”  was  repealed  by  Congress.  Further,  prior  to  the  U.S.  Supreme  Court  ruling,  on  January  28,  2021,  President  Biden  issued  an 
executive  order  that  initiated  a  special  enrollment  period  for  purposes  of  obtaining  health  insurance  coverage  through  the  PPACA 
marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that 
limit  access  to  healthcare,  including  among  others,  reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work 
requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the PPACA. 
On  August  16,  2022,  President  Biden  signed  the  Inflation  Reduction  Act  of  2022,  or  IRA,  into  law,  which,  among  other  things,  extends 
enhanced  subsidies  for  individuals  purchasing  health  insurance  coverage  in  PPACA  marketplaces  through  plan  year  2025.  The  IRA  also 
eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-
of-pocket cost and creating a new manufacturer discount program. It is possible that the PPACA will be subject to judicial or Congressional 
challenges in the future. It is unclear how such challenges and the healthcare measures of the Biden administration will impact the PPACA.

Other legislative changes have been proposed and adopted in the United States since the PPACA was enacted. For example, in August 2011, 
the Budget Control Act of 2011, among other things, created measures for spending reductions by U.S. Congress. A Joint Select Committee 
on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2012 through 2021, was 
unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs.

This includes aggregate reductions of Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and, 
due  to  subsequent  legislative  amendments  to  the  statute,  including  the  BBA,  will  remain  in  effect  through  2031  unless  additional 
Congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 4% in 
the  final  fiscal  year  of  this  sequester.  In  January  2013,  the  American  Taxpayer  Relief  Act  of  2012,  among  other  things,  further  reduced 
Medicare  payments  to  certain  providers,  and  increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to 
providers from three to five years.

Additionally,  there  have  been  several  recent  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, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple 
provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, the U.S. Department of Health and 
Humans Services (HHS)  released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform 
and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. In addition, the IRA, among 
other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, 
and subject drug manufacturers to 

77

civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated “maximum fair price” for 
such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs and biologics covered under Medicare Part B or 
Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through 
guidance, as opposed to regulation, for the initial years. These provisions will take effect progressively starting in fiscal year 2023, although 
they may be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on 
the pharmaceutical industry. Further, the Biden administration released an additional executive order on October 14, 2022, directing HHS to 
submit a report on how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for lowering drug costs 
for Medicare and Medicaid beneficiaries. It is unclear whether this executive order or similar policy initiatives will be implemented in the 
future.  At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical
and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and 
marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk 
purchasing. 

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 Conservation and Recovery Act and the Toxic Substances Control Act, affect our business. These and 
other laws govern the use, handling and disposal of various biologic, chemical and radioactive substances used in, and wastes generated by, 
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. Equivalent laws have been adopted in other countries that impose similar obligations.

U.S. Foreign Corrupt Practices Act

The  U.S.  Foreign  Corrupt  Practices  Act  of  1977,  as  amended  (FCPA),  prohibits  corporations  and  individuals  from  engaging  in  certain 
activities to obtain or retain business or secure any improper advantage, 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 employee or official of a foreign government or public international 
organization,  or  political  party,  political  party  official,  or  political  candidate  in  an  attempt  to  obtain  or  retain  business  or  to  otherwise 
influence a person working in an official capacity. The scope of the FCPA also includes employees and official of state-owned or controlled 
enterprises, which may include healthcare professionals in many countries. Equivalent laws have been adopted in other foreign countries that 
impose similar obligations.

Data Privacy and Security

In the ordinary course of our business, we may process personal or sensitive data. Accordingly, we are, or may become, subject to 
numerous data privacy and security obligations, including federal, state, local, and foreign laws, regulations, guidance, and industry standards 
related  to  data  privacy  and  security.  Such  obligations  may  include,  without  limitation,  the  Federal  Trade  Commission  Act,  the  California 
Consumer Privacy Act of 2018 (CCPA), the European Union’s General Data Protection Regulation 2016/679 (EU GDPR), and the United 
Kingdom’s  General  Data  Protection  Regulation  (UK  GDPR).  Several  states  within  the  United  States  have  also  enacted  or  proposed  data 
privacy and security laws. For example, Virginia passed the Consumer Data Protection Act, and Colorado passed the Colorado Privacy Act. 

The CCPA and EU GDPR are examples of the increasingly stringent and evolving regulatory frameworks related to personal data 
processing that may increase our compliance obligations and exposure for any noncompliance. For example, the CCPA imposes obligations 
on covered businesses to provide specific disclosures related to a business’s collection, use, and disclosure of personal data and to respond to 
certain requests from California residents related to their personal data (for example, requests to delete the individual’s personal data, and to 
opt out of certain personal data disclosures). The CCPA also provides for civil penalties and a private right of action for certain data breaches 
which may include an award of statutory damages. In addition, the California Privacy Rights Act of 2020 (CPRA), expands the CCPA by, 
among other things, giving California residents the ability to limit use of certain sensitive personal data and establishing a new California 
Privacy Protection Agency to implement and enforce the new law.

Foreign  data  privacy  and  security  laws,  such  as  the  EU  GDPR  and  UK  GDPR  (collectively,  GDPR),  impose  significant  and 
complex  compliance  obligations  on  entities  that  are  subject  to  those  laws.  For  example,  the  GDPR  imposes  stringent  requirements  for 
controllers and processors of personal data of persons in the European Union and/or United Kingdom, including, more robust disclosures to 
individuals  and  a  strengthened  individual  data  rights  regime,  shortened  timelines  for  data  breach  notifications,  limitations  on  retention  of 
information, increased requirements pertaining to special categories of data, such as health data, and additional obligations when we contract 
with  third-party  processors  in  connection  with  the  processing  of  the  personal  data.  The  GDPR  also  imposes  strict  rules  on  the  transfer  of 
personal data out of the European Union and/or the United Kingdom to the United States and other third countries. A July 2020 decision by 
the Court of Justice of the European Union, however, created significant uncertainty regarding how data can be legally transferred legally 
from  the  EU  and  the  United  States;  presently,  it  is  unclear  if  there  are  any  legally  viable  mechanisms  to  do  so.  In  addition,  the  GDPR 
provides  that  European  Union  member  states  may  make  their  own  further  laws  and  regulations  limiting  the  processing  of  personal  data, 
including genetic, biometric or health data.

The  GDPR  applies  extraterritorially,  and  we  may  be  subject  to  the  GDPR  because  of  our  data  processing  activities  that  involve  the 
personal  data  of  individuals  located  in  the  European  Union  and/or  the  United  Kingdom,  such  as  in  connection  with  any  European  Union 
and/or United Kingdom clinical trials. Failure to comply with the requirements of the GDPR and the applicable national data protection laws 
of  the  European  Union  member  states  and/or  United  Kingdom  may  result  in  fines  of  up  to  €20,000,000  for  breaches  of  the  EU  GDPR, 
£17,500,000 for breaches of the UK GDPR, or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is 
higher,  and  other  administrative  penalties.  GDPR  regulations  may  impose  additional  responsibility  and  liability  in  relation  to  the  personal 
data that we process and we may be required to put in place additional mechanisms to ensure compliance with the new data protection rules. 

See the section titled “Item 3.D. – Risk Factors” for additional information about the laws and regulations to which we are or may 

become subject and about the risks to our business associated with such laws and regulations.

Good Manufacturing Practice

All facilities and techniques used in the manufacture of products for clinical use or for sale in China must be operated in conformity with
good  manufacturing  practice  guidelines  as  established  by  the  NMPA.  Failure  to  comply  with  applicable  requirements  could  result  in  the 
termination of manufacturing and significant fines.

A.

Operating Results. 

Overview

We are a clinical-stage immunology focused biopharmaceutical company developing innovative treatments to transform the lives of patients. 

Our portfolio is led by eblasakimab, a potential first-in-class human monoclonal antibody that binds to the IL-13 receptor α1 subunit (IL-
13Rα1), blocking signaling of two pro-inflammatory cytokines, IL-4 and IL-13 which are central to triggering symptoms of atopic dermatitis, 
such  as  redness  and  itching  of  the  skin.  Eblasakimab  has  the  potential  to  be  a  best-in-disease  for  atopic  dermatitis  and  asthma.  We  are 
currently conducting a Phase 2b clinical trial investigating eblasakimab as a therapeutic antibody for moderate-to-severe atopic dermatitis. 
Our previous trial results demonstrate a competitive profile with the potential to differentiate over existing therapies. We expect to report top-
line data from this trial in early July 2023. We are also developing farudodstat, an orally active, potent inhibitor of human DHODH that has 
the potential to be a best-in-class therapy in autoimmune disease.

Since our inception in 2010, we have devoted substantially all of our resources to acquiring rights to, and developing our product candidates, 
including preclinical studies and clinical trials and providing general and administrative support 

80

 
 
 
 
 
   
   
 
 
for  our  operations.  We  have  not  generated  any  revenue  from  product  sales  and  we  do  not  currently  have  any  products  approved  for 
commercialization.  We  have  financed  our  operations  through  a  combination  of  debt  and  equity  financings,  including  public  and  private 
offerings, and government grants. 

2023 Private Placement

On February 24, 2023, we entered into a Unit Purchase Agreement (the Purchase Agreement), with fund entities affiliated with BVF Partners 
L.P.  (collectively,  BVF)  and  the  other  purchasers  named  therein  (collectively,  the  Purchasers),  pursuant  to  which  we  agreed  to  sell  to  the 
Purchasers,  in  a  private  placement  offering,  an  aggregate  of  (i)  112,359,550  ordinary  shares,  which  includes  (ii)  pre-funded  warrants 
exercisable  for  ordinary  shares  (Pre-Funded  Warrants),  to  purchase  five  ordinary  shares,  represented  by  our  ADSs,  at  a  purchase  price  of 
$0.178 per ordinary share (or the equivalent of $0.89 per ADS) and $0.8895 per Pre-Funded Warrant (the 2023 Private Placement). The 2023 
Private Placement closed on February 27, 2023, and resulted in gross proceeds to us of approximately $20.0 million. 

As  part  of  the  2023  Private  Placement,  the  Purchasers  also  received  two  tranches  of  warrants  exercisable  in  the  aggregate  for  up  to 
55,309,112 ADSs (or Pre-Funded Warrants exercisable for ADSs). The first tranche of warrants is comprised (i) 50% of warrants that are 
exercisable upon issuance and until 60 days after the public announcement of our topline data from our TREK-AD Phase 2b clinical trial
investigating  eblasakimab  in  atopic  dermatitis  (the  eblasakimab  announcement)  at  an  exercise  price  of  $1.30  per  ADS,  and  (ii)  50%  of 
warrants which can only be exercised within 60 days after the eblasakimab announcement at an exercise price based on the higher of $1.30 
and a 50% discount to the ADSs’ ten-day volume‐weighted average price (VWAP) measured across a specified period after the eblasakimab 
announcement. The second tranche of warrants is similarly comprised (i) 50% of warrants that are exercisable upon issuance until 60 days 
after  the  public  announcement  of  topline  interim  data  from  our  planned  Phase  2  proof  of  concept  trial  investigating  farudodstat  (the 
farudodstat announcement) at an exercise price of $1.63 per ADS, and (ii) 50% of warrants which can only be exercised within 60 days after 
the farudodstat announcement at an exercise price based on the higher of $1.63 and a 50% discount to the ADS VWAP measured across a 
specified period after the farudodstat announcement (collectively, the Tranche Warrants). The Tranche Warrants have a term of five years and 
include  a  mandatory  exercise  provision,  subject  to  the  satisfaction  of  certain  pre-specified  conditions.  If  all  Tranche  Warrants  are  fully-
exercised we would receive an additional $80.0 million in gross proceeds.

Pursuant  to  the  Purchase  Agreement,  we  granted  BVF  the  right  to  nominate  one  individual  to  our  Board  of  Directors  and  are  required  to 
recommend to our shareholders to elect such nominee until such time that BVF retains beneficial ownership of less than 9.9% of the issued 
and outstanding ordinary shares (including any Pre-Funded Warrants BVF holds as if fully exercised).

2021 Private Placement

In  February  2021,  we  sold  25,568,180  ordinary  shares  (the  equivalent  of  5,113,636  ADSs)  in  a  private  placement  for  net  proceeds  of 
approximately  $18.0  million  pursuant  to  a  securities  purchase  agreement  the  Company  entered  into  with  the  purchasers  in  the  private 
placement.

Underwritten Public Offering

In  March  2021,  we  sold  17,250,000  ADSs  representing  86,250,000  ordinary  shares  in  an  underwritten  public  offering  for  net  proceeds  of 
approximately $64.9 million after deducting underwriting discounts and commissions and offering expenses.

At-the-market Offering

On October 9, 2020, we entered into an Open Market Sale AgreementSM as amended on September 13, 2022 (the ATM Sale Agreement) with 
Jefferies LLC, pursuant to which we may issue and sell ADSs from time to time, through at-the-market offerings under which Jefferies LLC 
will act as sales agent and/or principal.

During  the  year  ended  December  31,  2020,  we  raised  net  proceeds  of  approximately  $7.4  million  by  offering  19,720,500  ordinary  shares 
(equivalent of 3,944,100 ADSs) under the ATM Sale Agreement and during the year ended December 31, 2021, we raised net proceeds of 
approximately $14.1 million under ATM Sale Agreement by offering 24,594,360 ordinary shares (equivalent of 4,918,872 ADSs). During the 
year ended December 31, 2022, there was no issuance of ordinary shares/ADS under the ATM Sale Agreement. 

81

We did not generate revenue for the year ended December 31, 2021 and 2022. To date we have outsourced our manufacturing and clinical 
operations to third parties. We do not intend to operate our own clinical trials or build or acquire infrastructure for manufacturing our drugs 
for  clinical  or  commercial  supply.  All  of  our  clinical  supplies  are  manufactured  in  accordance  with  cGMP  using  high  quality  contract 
manufacturing organizations based in the United States, Europe and Asia. 

As of December 31, 2022, we had cash and cash equivalents of $56.9 million. We have never been profitable and have incurred significant 
net losses in each period since our inception. Our consolidated net loss attributable to ordinary shareholders for the years ended December 
31, 2020, 2021 and 2022 was $16.2 million, $31.3 million and $51.4 million, respectively. As of December 31, 2022, we had an accumulated 
deficit of $278.4 million. Our primary use of cash is to fund research and development costs. Our operating activities used $15.1 million, 
$34.0  million  and  $38.4  million  of  cash  flows  during  the  years  ended  December  31,  2020,  2021  and  2022,  respectively.  We  expect  to 
continue to incur significant expenses and operating losses for the foreseeable future.

We expect expenses to be incurred in connection with our ongoing activities as we:

•

•

Continue to invest in the clinical development of our product candidates, including in connection with the following planned 
and ongoing clinical trials:

o

o

o

Eblasakimab Phase 2b clinical trial in atopic dermatitis; 

Eblasakimab Phase 2 clinical trial in dupilumab-experienced atopic dermatitis patients; 

Farudodstat Phase 2a clinical trial in alopecia areata; and

o Any additional clinical trials that we may conduct for product candidates;

Engage  third  parties  to  manufacture  product  candidates  for  clinical  trials  and,  if  any  product  candidates  are  approved,  for 
commercialization;

• Maintain, expand and protect our intellectual property portfolio; and

•

Incur additional costs with operating as a U.S. public company.

We  will  continue  to  require  additional  capital  to  support  our  operating  activities  as  we  advance  our  product  candidates  through  clinical 
development,  regulatory  approval  and,  if  any  of  our  product  candidates  are  approved,  commercialization.  The  amount  and  timing  of  our 
future funding requirements will depend on many factors, including the pace and results of our product development efforts.

Out-licensing Agreements

To date, we have out-licensing agreements with Kyungnam Biopharma (previously known as BioGenetics).

BioGenetics – License of varlitinib for South Korea

On February 27, 2019, we entered into a collaboration and license agreement with BioGenetics, pursuant to which we granted BioGenetics 
the  exclusive  right  to  commercialize,  and  if  agreed,  manufacture,  varlitinib  for  the  treatment  of  all  indications  in  South  Korea.  In 
consideration  of  the  rights  granted  to  BioGenetics  under  the  agreement,  we  received  an  upfront  payment  of  $2  million  as  revenue  from 
BioGenetics and are eligible to receive up to $11 million in sales and development milestones where the thresholds for payment of such sales 
milestones depend on the aggregate of net sales of varlitinib and farudodstat products under our agreements with BioGenetics. We are also 
eligible to receive tiered double-digit royalties on net sales up to a percentage within the mid-twenties. BioGenetics will be responsible for 
obtaining initial and all subsequent regulatory approvals of varlitinib in South Korea. We may provide clinical drug supplies to BioGenetics 
required  for  regulatory  filings  and  for  commercialization  of  products,  pursuant  to  a  separate  manufacturing  and  supply  agreement  to  be 
agreed between the parties. 

82

BioGenetics – License of farudodstat for South Korea

On March 11, 2019, we entered into a collaboration and license agreement with BioGenetics, pursuant to which we granted BioGenetics the 
exclusive  right  to  commercialize,  and  if  agreed,  manufacture,  farudodstat  for  the  treatment  of  all  indications  in  South  Korea,  excluding 
topically  administered  products  for  the  treatment  of  keratinocyte  hyperproliferative  disorders  and  certain  non-melanoma  skin  cancers.  In 
consideration  of  the  rights  granted  to  BioGenetics  under  the  agreement,  we  received  an  upfront  payment  of  $1  million  as  revenue  from 
BioGenetics  and  are  eligible  to  receive  up  to  $8  million  in  sales  and  development  milestones,  the  thresholds  for  payment  of  such  sales 
milestones  being  the  aggregate  of  sales  of  varlitinib  under  the  license  summarized  above  and  sales  of  farudodstat  products.  We  are  also 
eligible to receive tiered double-digit royalties on net sales up to a percentage within the mid-twenties. BioGenetics agreed to contribute to 
the  global  R&D  costs  incurred  by  ASLAN  in  the  clinical  development  of  farudodstat  in  acute  myeloid  leukemia.  BioGenetics  will  be 
responsible  for  obtaining  initial  and  all  subsequent  regulatory  approvals  of  farudodstat  in  South  Korea.  We  may  provide  clinical  drug 
supplies  to  BioGenetics  required  for  regulatory  filings  and  for  commercialization  of  products,  pursuant  to  a  separate  manufacturing  and 
supply agreement to be agreed between the parties. 

In-licensing Agreements

We  are  required  to  make  milestone  payments  upon  the  achievement  of  certain  development,  regulatory  and  commercial  milestones  and 
royalties based on the net sales of the licensed products and therefore, we expect our results of operations will continue to be affected by 
these  agreements.  For  the  years  ended  December  31,  2021  and  2022,  we  did  not  make  any  other  payments  related  to  the  in-license 
agreements. See “Item 4.B. Information on the Company – Business Overview—License and Collaboration Agreements” for a description of 
our license agreements, which includes a description of the termination provisions of these agreements.

Key Components of Results of Operations

Revenues

To  date,  we  have  not  generated  any  revenue  from  product  sales  and  do  not  expect  to  generate  any  revenue  from  product  sales  until  our 
product candidates receive regulatory approval. We did not generate revenue for the years ended December 31, 2021, and 2022.

Research and Development Expenses

The largest component of our operating expenses since inception has been research and development activities, including the preclinical and 
clinical development of our product candidates. Research and development costs are expensed as incurred. Our research and development 
expenses primarily consist of:

•

•

•

•

•

•

Costs  incurred  under  agreements  with  contract  research  organizations  and  investigative  sites  that  conduct  preclinical  studies 
and clinical trials;

Costs  related  to  manufacturing  pharmaceutical  active  ingredients  and  product  candidates  for  preclinical  studies  and  clinical 
trials;

Salaries  and  personnel-related  costs,  including  bonuses,  related  benefits  and  share-based  compensation  expense  for  our 
scientific personnel performing or managing out-sourced research and development activities;

Fees paid to consultants and other third parties who support our product candidate development;

Other costs incurred in seeking regulatory approval of our product candidates; and

Allocated facility-related costs and overhead.

Product  candidates  in  later  stages  of  clinical  development  generally  have  higher  development  costs  than  those  in  earlier  stages  of  clinical 
development, primarily due to the increased size and duration of later-stage clinical trials. Accordingly, we expect research and development 
costs to increase significantly for the foreseeable future as our programs progress. However, we do not believe that it is possible at this time 
to  accurately  project  total  program-specific  expenses  through  commercialization.  Our  expenditures  on  current  and  future  preclinical  and 
clinical development programs are subject to 

83

numerous  uncertainties  in  timing  and  cost  to  completion.  In  addition,  we  may  enter  into  additional  collaboration  arrangements  for  our 
product candidates, which could affect our development plans or capital requirements.

We allocate direct costs to product candidates when they enter into clinical development. For product candidates in clinical development, we 
allocate  development  and  manufacturing  costs  to  our  product  candidates  on  a  program-specific  basis,  and  we  include  these  costs  in  the 
program-specific expenses. Our direct research and development expenses tracked by program consist primarily of external costs, such as 
fees  paid  to  outside  consultants,  CROs,  and  contract  manufacturing  organizations  in  connection  with  our  preclinical  development, 
manufacturing and clinical development activities. We do not allocate employee costs or facility expenses, including other indirect costs, to 
specific  programs  because  these  costs  are  deployed  across  multiple  programs  and,  as  such,  are  not  separately  presented.  We  use  internal 
resources  primarily  to  oversee  research  and  discovery  as  well  as  for  managing  our  preclinical  development,  process  development, 
manufacturing  and  clinical  development  activities.  These  employees  work  across  multiple  programs  and,  therefore,  we  do  not  track  their 
costs by program.

The table below summarizes our research and development expenses incurred by program for the periods presented:

General and Administrative Expenses

General and administrative expenses consist of personnel costs, allocated risk expenses and other expenses for outside professional services, 
including  legal,  audit  and  accounting  services.  Personnel  costs  consist  of  salaries,  bonuses,  benefits  and  stock-based  compensation.  Other 
general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional 
fees, expenses associated with obtaining and maintaining patents and costs of our information systems. 

Non-Operating Income and Expenses

Other Income

Other  non-operating  income  is  the  ADS  issuance  contribution  receivable  from  J.P.  Morgan  Chase  Bank  N.A.,  the  Custodian  and  the 
Depositary,  as  part  of  the  conversion  of  ordinary  shares  to  ADSs  due  to  the  Taiwan  delisting  in  2020  and  issuance  of  new  ADSs.  As  of 
December  31,  2021,  the  Company  recognized  a  total  of  $1.1  million,  as  other  non-operating  income  mainly  from  the  ADS  issuance 
contribution and did not recognize any related other income as of December 31, 2022.

Other Gains and Losses, Net

Other gains and losses are primarily net gains and losses from realized and unrealized currency exchange differences, valuation on fair value 
changes of financial assets and liabilities at fair value through profit or loss incurred during the period. For the years ended December 31, 
2020, 2021 and 2022, other gains and losses were ($0.1) million, $1.1 million and ($0.03) million, respectively.

Research and development expenses increased by $16.0 million from $22.0 million for the year ended December 31, 2021 to $38.0 million 
for  the  year  ended  December  31,  2022.  The  increase  was  driven  primarily  by  the  increase  of  clinical  development  expenses  and 
manufacturing costs related to eblasakimab.

Other Income 

As  of  December  31,  2021,  the  Company  recognized  a  total  $1.1  million,  as  other  non-operating  income  mainly  from  the  ADS  issuance 
contribution and did not recognize any related other income as of December 31, 2022.

Other Gains and Losses, Net

Other net gains for the year ended December 31, 2021, were $1.1 million and other net losses for the year ended December 31, 2022 were 
$0.03 million. The decrease was primarily due to net foreign exchange losses; and the lower net gain on the fair value changes of financial 
assets and liabilities, which were due to the significant historical volatility comparing 2021 and 2022.

Comparison of the Years Ended December 31, 2020 and 2021

For the discussion covering the comparison between the years ended December 31, 2021 and 2020, please refer to “Item 5” of our Annual 
Report on Form 20-F for the year ended December 31, 2021 filed with the SEC.

B.

Liquidity and Capital Resources.

Since  inception,  we  have  invested  most  of  our  resources  in  the  development  of  our  product  candidates,  building  our  intellectual  property 
portfolio, developing our supply chain, conducting business planning, raising capital and providing support for our operations. To date we 
have funded our operations through public and private placements of equity securities, upfront and milestone payments received from our 
collaborators,  funding  from  governmental  bodies  and  interest  income  from  banks.  As  of  December  31,  2021,  we  raised  aggregate  gross 
proceeds of $280.6 million from private and public offerings, we had received aggregate gross upfront payments of $13.3 million from our 
collaborators and received an aggregate of $7.3 million in grants from government bodies. Since our inception, we have incurred net losses 
and  negative  cash  flows  from  our  operations.  Substantially  all  of  our  losses  have  resulted  from  funding  our  research  and  development 
programs and general and administrative costs associated with our operations. We incurred net losses attributed to the stockholders of the 
company  of  $16.2  million,  $31.3  million  and  $51.4  million  for  the  years  ended  December  31,  2020,  2021  and  2022,  respectively.  As  of 
December  31,  2021  and  2022,  we  had  an  accumulated  deficit  of  $227.0  million  and  $278.4  million,  respectively.  Our  operating  activities 
used  $15.1  million,  $34.0  million  and  $38.4  million  of  cash  outflows  during  the  years  ended  December  31,  2020,  2021  and  2022, 
respectively. 

As of December 31, 2022, we had cash and cash equivalents of $56.9 million. From October 9, 2020 through February 19, 2021, we sold 
8,862,972 ADSs for net proceeds of $21.5 million under the ATM Sale Agreement with Jefferies LLC through at-the-market offerings, of 
which  net  proceeds  of  $14.1  million  was  raised  from  January  1,  2021  through  February  19,  2021.  In  February  2021,  we  sold  25,568,180 
ordinary shares (an equivalent of 5,113,636 ADSs) in a private placement for gross proceeds of approximately $18.0 million pursuant to a
securities purchase agreement. In March 2021, we sold 17,250,000 ADSs representing 86,250,000 ordinary shares in an underwritten public 
offering for net proceeds of $64.9 million after deducting underwriting discounts and commissions and offering expenses. On July 12, 2021, 
we entered into a Loan, Guaranty, and Security Agreement with K2 HealthVentures LLC (K2HV) which provides us for up to $45.0 million 
of loan facility. The first tranche of $20.0 million was closed and received in 2021. In January 2022, we drew down the second tranche of the 
loan facility provided by K2HV and the funds were received in February 2022. Total proceeds of approximately $117.0 million was raised 
for year ended December 31, 2021. During the year ended December 31, 2022, there was no issuance of ordinary shares/ADS.

On February 24, 2023, the Company entered into a Unit Purchase Agreement (Purchase Agreement) with fund entities affiliated with BVF 
Partners L.P. (collectively, BVF) private placement (Private Placement). The Private Placement was on February 27, 2023 (Closing), subject 
to  customary  closing  conditions.  The  Private  Placement  is  expected  to  result  in  gross  proceeds  to  the  Company  of  approximately  $20.0 
million, and an additional $80.0 million in gross proceeds to the Company if all Tranche Warrants are fully-exercised. 

We have not achieved profitability since our inception and we expect to continue to incur net losses for the foreseeable future. Based on our 
current operating plan, we believe that our existing cash and cash equivalents, including the proceeds from the Private Placement, will enable 
us to fund our operating expenses and capital requirements for at least the next twelve months from December 31, 2022.

We expect to fund our long-term anticipated operating and capital expenditure requirements through public and private offerings of our ADSs 
and ordinary shares.

Our future capital requirements will depend on many factors, including: 

•

•

•

The scope, progress, results and costs of drug discovery, preclinical development, laboratory testing and clinical trials for our 
product candidates;

The costs, timing and outcome of regulatory review of our product candidates;

The costs of establishing or contracting for sales, marketing and distribution capabilities if we obtain regulatory approvals to 
market our product candidates;

87

•

•

•

•

•

•

•

The costs of securing and producing drug substance and drug product material for use in preclinical studies, clinical trials and 
for use as commercial supply;

The costs of securing manufacturing arrangements for development activities and commercial production;

The scope, prioritization and number of our research and development programs;

The  extent  to  which  we  are  obligated  to  reimburse,  or  entitled  to  reimbursement  of,  clinical  trial  costs  under  future 
collaboration agreements, if any;

The extent to which we acquire or in-license other product candidates and technologies;

The  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights 
and defending intellectual property-related claims; and

The  effects  of  the  disruptions  to  and  volatility  in  the  credit  and  financial  markets  in  the  United  States  and  worldwide  from 
geopolitical and macroeconomic events, including the COVID-19 pandemic, the ongoing Russia-Ukraine conflict and related 
sanctions, and bank failures.

We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we 
currently expect. If our planned preclinical and clinical trials are successful, or our other product candidates enter clinical trials or advance 
beyond the discovery stage, we will need to raise substantial additional financing in the future to fund our operations. In order to meet these 
additional  cash  requirements,  we  may  incur  debt,  out-license  certain  intellectual  property  and  seek  to  sell  additional  equity  or  convertible 
securities that may result in dilution to our stockholders. If we raise additional funds through the issuance of equity or convertible securities, 
these  securities  could  have  rights  or  preferences  senior  to  those  of  our  ADSs  and  ordinary  shares  and  any  indebtedness  could  contain 
covenants that restrict our operations. There can be no assurance that we will be able to obtain additional equity or debt financing on terms 
acceptable to us, if at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions 
and the disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from macroeconomic 
events, such as the COVID-19 pandemic, the ongoing Russia-Ukraine conflict and related sanctions, and bank failures, including severely 
diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, 
and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing 
more difficult, more costly and more dilutive.

K2HV Loan Facility 

Loan Agreement

In July 2021, we entered into a Loan, Guaranty, and Security Agreement (Loan Agreement) with ASLAN Pharmaceuticals Pte. Ltd (ASLAN 
Singapore)  as  guarantor,  the  lenders  from  time  to  time  party  thereto,  K2  HealthVentures  LLC  as  administrative  agent  and  Ankura  Trust 
Company, LLC as collateral agent. The Loan Agreement provides for up to $45.0 million of delayed draw term loans, consisting of (i) the 
first tranche of $20.0 million available at closing, (ii) the second and third traches in the aggregate amount of $10.0 million subject to our 
achievement  of  certain  clinical  milestones  related  to  farudodstat  and  eblasakimab  and  (iii)  an  uncommitted  fourth  tranche  of  up  to  $15.0 
million.

We borrowed the full $20.0 million first tranche of term loans at closing. We intend to use the proceeds of the term loans to advance the 
clinical development of farudodstat, as well as for general corporate purposes. In connection with entering into the Loan Agreement, we paid 
off our outstanding loans with CSL Finance Pty Ltd in the amount of $4.2 million.

On January 5, 2022, we drew down the second tranche of the loan facility provided by K2HV pursuant to the Loan Agreement. The second 
tranche milestone was completed, and the full funds were received on February 4, 2022. As a result of the drawdown of the second tranche of 
the loan facility, the number of ordinary shares exercisable under the K2 Warrant increased to 2.95% of $25 million, being the aggregate term 
loan advances at that date, divided by the warrant price of $0.5257 per ordinary share (equivalent to $2.6285 per ADS), same as the first 
tranche terms.

The term loans bear interest at a floating rate equal to the greater of (i) the prime rate published by Wall Street Journal plus 5.00% and (ii) 
8.25%  per  annum.  The  monthly  payments  are  interest-only  until  August  1,  2023,  which  may  be  extended  to  August  1,  2024  upon  our 
achievement  of  certain  clinical  milestones.  Subsequent  to  the  interest-only  period,  the  term  loans  will  be  payable  in  equal  monthly 
installments of principal plus accrued and unpaid interest, through the maturity date which is July 1, 2025. We paid the lenders a one-time 
$255,000 facility fee at closing and will be obligated to pay for an additional facility fee equal to 0.85% of any term loans borrowed under 
the fourth tranche. In addition, we are obligated to pay a final payment fee of 6.25% of the original principal amount of the term loans at the 
maturity date. We may elect to prepay all, but not less than all, of the term loans prior to the term loan maturity date, subject to a prepayment 
fee of up to 3.0% of the then outstanding principal balance. After repayment, no term loans may be borrowed again.

Borrowings  under  the  loan  facility  are  secured  with  collateral  over  our  cash  and  other  personal  property,  with  the  exception  of  (i)  our 
registered  intellectual  property  assets,  (ii)  personal  property  to  the  extent  that  granting  of  security  over  any  such  personal  property  would 
constitute a breach of or result in the termination of, or require any consent not obtained under, any license, agreement, instrument or other 
document evidencing or giving rise to such property, or is otherwise prohibited by any requirement of law, and (iii) our equity interests in 
JAGUAHR. The Loan Agreement includes customary affirmative and negative covenants applicable to us and our subsidiaries, including, 
among  other  things,  restrictions  on  indebtedness,  liens,  investments,  mergers,  dispositions,  cash  management,  dividends  and  other 
distributions. In addition, the Loan Agreement also includes customary events of default, including, but not limited to, failure to pay interest, 
principal and fees or other amounts when due, material misrepresentations or misstatements, covenant defaults, certain cross defaults to other 
material indebtedness, certain judgment defaults and events of bankruptcy or insolvency. Upon the occurrence and continuance of an event of 
default, the lenders may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan 
Agreement and other loan documents.

K2 Warrant and Participation Rights

In connection with the closing of the Loan Agreement, we issued a warrant to purchase ordinary shares (K2 Warrant) to K2 HealthVentures 
Equity Trust LLC. The number of ordinary shares exercisable under the K2 Warrant equals (i) 2.95% of the aggregate outstanding principal 
amount of the term loans funded to us divided by (ii) the warrant price of $0.5257 per share (equivalent to $2.6285 per ADS) (subject to 
adjustment as provided therein). The K2 Warrant also includes a cashless exercise feature allowing the holder to receive shares underlying 
the warrant in an amount reduced by the aggregate exercise price that would have been payable upon exercise of the warrant for such shares. 
In  addition,  subject  to  compliance  with  applicable  securities  laws  (including  any  holding  period  requirements),  we  are  required  to  use 
commercially  reasonable  efforts  to  facilitate  and  take  all  other  actions  required  to  enable  the  deposit  of  any  or  all  of  the  ordinary  shares 
exercisable under the Warrant with our depositary for the issuance of American Depositary Shares. The K2 Warrant is exercisable until its 
expiration on July 12, 2031. The K2 Warrant also provides for automatic cashless 

89

exercise  or  assumption  as  a  result  of  certain  transactions  involving  a  merger,  acquisition  or  sale  of  the  company,  as  set  forth  in  the  K2 
Warrant.

The Loan Agreement also provides K2 HealthVentures Equity Trust LLC with the right to participate in an aggregate amount of up to $5.0 
million  in  any  offering  of  our  American  Depositary  Shares,  ordinary  shares,  common  stock,  convertible  preferred  stock  or  other  equity 
securities (or certain other convertible instruments but excluding non-convertible debt securities), but excluding any at-the-market offerings 
or  facilities,  on  the  same  terms,  conditions  and  pricing  afforded  to  others  participating  in  such  offering;  provided  that  with  respect  to  any 
public offering, we are required to use commercially reasonable efforts to provide K2 HealthVentures Equity Trust LLC with the opportunity 
to invest in each such offering if it is lawful to do so (or if the offering is an underwritten public offering pursuant to a registration statement 
under the Securities Act of 1933, as amended, to use commercially reasonable efforts to cause the underwriters for such offering to offer K2 
HealthVentures Equity Trust LLC an allocation of securities in such offering).

(33,266 ) 

The use of cash resulted primarily from our net losses adjusted for non-cash charges and changes in components of our operating assets and 
liabilities. The primary use of our cash was to fund the development of our research and development activities, regulatory and other clinical 
trial costs, and related supporting administration. Our prepayments and other current assets, accounts payable and other payables balances 
were affected by the timing of vendor invoicing and payments.

Net cash used in operating activities was $34.0 million and $38.4 million for the years ended December 31, 2021 and 2022, respectively. The 
increase  of  net  cash  used  in  operating  activities  for  2022  was  primarily  due  to  an  increase  of  research  and  development  activities  and  its 
related general and administrative expenses from 2021 to 2022. These increases were mainly attributable to costs associated with the ongoing 
TREK-AD Phase 2b clinical trial.  

Net cash used in operating activities was $15.1 million and $34.0 million for the years ended December 31, 2020 and 2021, respectively. The 
increase  of  net  cash  used  in  operating  activities  for  2021  was  primarily  due  to  an  increase  of  $4.7  million  related  to  general  and 
administrative expenses, and an increase of $12.7 million related to research and development expenses from 2020 to 2021. These increases 
were mainly attributable to various financing activities to support preparation for the TREK-AD Phase 2b clinical trial. 

Net Cash Used in Investing Activities

Net  cash  used  in  investing  activities  was  $28,155  for  the  year  ended  December  31,  2021.  Net  cash  provided  in  investing  activities  was 
$414,699 for the year ended December 31, 2022. The increase in cash in investing activities for 2022 was primarily due to the Company’s 
return on investments in the money market.

Net cash provided by investing activities was $927 for the year ended December 31, 2020. Net cash used in investing activities was $28,155 
for the year ended December 31, 2021. The decrease in cash in investing activities for 2021 was primarily due to purchases of property, plant 
and equipment for our headcount in the US. 

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $7.2 million, $109.9 million and $4.7 million for the years ended December 31, 2020, 2021 and 
2022, respectively, which consisted primarily of net proceeds from our issuance of ADSs from at-the-market offerings from the year 2020 to 
2021 and the loan from K2 HealthVentures LLC for the year ended

Compensation of Executive Officers and Directors

Incentive Compensation

For the year ended December 31, 2022, the aggregate compensation accrued or paid to the members of our executive officers for services in 
all capacities was $5,041,904.

We  did  not  set  aside  or  accrue  any  amounts  for  pension,  retirement  or  similar  benefits  to  members  of  our  board  of  directors  or  executive 
officers in the year ended December 31, 2020, 2021 and 2022.

We maintain the Senior Management Team (SMT) Long Term Incentive Plans (LTIP), pursuant to which bonus entitlement unit awards were 
granted in 2017, 2018 and 2019. For more information on our LTIPs, see the discussion below under “—Compensation Plans—2017, 2018 
and 2019 SMT LTIPs.” During the years ended December 31, 2020, 2021 and 2022, we had no awards granted under LTIP.

Executive Officer Compensation

Equity Awards

On December 10, 2020, our Board of Directors (Board) approved the 2020 Equity Incentive Plan (the 2020 EIP). The 2020 EIP, among other 
things, provides for the grant of restricted stock awards, stock options and other equity-based awards to employees, officers, directors, and 
consultants. For more information on our equity awards, see the discussion below under—“Option Grants.”

Employment Agreements with Executive Officers

We have entered into employment agreements with our executive officers. Each of our executive officers is employed for a continuous term 
unless either we or the executive officer gives prior notice to terminate such employment. We may terminate the employment for just cause, 
at  any  time,  without  notice  or  remuneration,  for  certain  acts  of  the  executive  officer.  An  executive  officer  may  terminate  his  or  her 
employment at any time by giving a minimum period of prior written notice, three months in some cases, six months in others, except for our 
Chief Medical Officer (CMO), who has an “at will” contract under California law. This may be terminated at any time by either us or the 
executive by notice in writing.

Each  executive  officer  has  agreed  to  maintain  the  confidentiality  of  any  confidential  information,  both  during  and  after  the  employment 
agreement expires or is earlier terminated. In addition, all executive officers except our CMO have agreed to be bound by a non-compete 
covenant that prohibits each executive officer from competing with us, directly or indirectly, during his or her employment and for a period 
of  months  (minimum  of  three)  after  the  termination  of  his  or  her  employment.  Our  CMO  has  agreed  to  be  bound  by  a  non-solicitation 
covenant  that  prohibits  him  during  his  employment  and  for  one  year  after  his  employment  with  us  ends,  either  directly  or  through  others 
soliciting, inducing, or encouraging any employee, consultant, or independent contractor of ours to terminate his, her or its relationship with 
us.

94

Option Grants

We have made grants of options to our employees pursuant to our 2014 Employee Share Option Scheme Plan (the 2014 Plan) and our 2017 
Employee Share Option Plan (the 2017 Plan). Options granted pursuant to the 2014 Plan are either vested in full as of the date of grant or are 
25% vested as of the date of grant, with the remaining 75% vesting in equal annual installments over the three years following the date of 
grant. Options granted pursuant to the 2017 Plan vest in full upon the two-year anniversary of the date of grant. On December 10, 2020, the 
Board approved the 2020 EIP. The 2020 EIP, among other things, provides for the grant of restricted stock awards, stock options and other 
equity-based awards to employees, officers, directors, and consultants. The maximum number of ordinary shares that may be issued under 
the 2020 EIP is 20,676,974 ordinary shares (an equivalent of 4,135,394 ADSs) of the Company, each ADS representing five ordinary shares. 
As disclosed in ITEM 18 FINANCIAL STATEMENTS, Note 25(c), the effect of the ADS Ratio Change on the Nasdaq Capital Market took
place  at  the  opening  of  trading  on  March  13,  2023.  Awards  granted  under  the  2020  EIP  in  substitution  for  any  options  or  other  equity  or 
equity-based  awards  granted  by  an  entity  before  the  entity’s  merger  or  consolidation  with  us  or  our  acquisition  of  the  entity’s  property  or 
stock will not reduce the number of ordinary shares available for grant under the 2020 EIP, but will count against the maximum number of 
ordinary shares that may be issued upon the exercise of incentive stock options. References in this summary to ordinary shares include an 
equivalent number of our ADSs. 

Vested  options  may  be  exercised  during  their  term  and  for  varying  periods  following  termination  of  service,  depending  on  the  reason  for 
termination. Options will be adjusted to account for any changes in capitalization or certain other corporate events and are not transferable 
(but may be exercised by the individual’s heirs in the case of death, to the extent vested at the time of death). 

SMT LTIPs

During the year ended December 31, 2022, we had no performance based compensation programs.

Other Programs

ASLAN  Pharmaceuticals  Pte.  Ltd.  has  adopted  defined  contribution  plans  which  are  post-employment  benefit  plans  under  which  we  pay 
fixed  contributions  into  the  Singapore  Central  Provident  Fund  on  a  mandatory  basis.  ASLAN  Pharmaceuticals  Pte.  Ltd.  has  no  further 
payment obligations once the contributions have been paid. The contributions are recognized as employee compensation expense when they 
are due.

Director Compensation

We provide only cash compensation to each of our non-executive directors not serving as a representative of a shareholder for the time and 
effort  necessary  to  serve  as  a  member  of  our  Board.  The  compensation  of  the  non-executive  directors  complies  with  our  Articles  and  is 
determined by our remuneration committee and Board as a whole, based on a review of individual contributions to our operations and current 
practices in other companies.

2014 Employee Share Option Scheme Plan

We maintain the 2014 Plan, pursuant to which we have granted share options to our employees, directors and consultants. The 2014 Plan 
became  effective  on  August  26,  2014,  and  has  a  term  of  ten  years.  After  the  effective  date  of  the  2017  Plan,  no  additional  awards  were 
granted, and no future awards are allowed to be granted, under the 2014 Plan.

 
  
  
 
    
 
 
 
 
 
    
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
 
 
  
 
 
 
    
 
 
 
 
 
 
    
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
 
 
  
 
 
 
    
 
 
 
 
 
 
    
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
 
 
  
 
 
 
    
 
 
 
 
 
 
    
  
  
 
 
 
    
 
 
 
 
 
 
    
  
  
  
 
 
 
    
 
 
 
 
 
 
    
 
 
  
 
 
 
    
 
 
 
 
 
 
    
 
 
 
 
 
 
 
 
 
The 2014 Plan may be administered by our Board or a committee thereof, which administrator has the authority to: determine the individuals 
to whom awards may be granted and the terms of such awards; amend the terms of any outstanding award, provided that the consent of the 
grantee  is  required  where  the  grantee’s  rights  would  be  adversely  affected;  construe  and  interpret  the  terms  of  the  2014  Plan  and  awards 
granted thereunder; and take such other action, not inconsistent with the terms of the 2014 Plan, as it deems appropriate.

97

The number of shares under the 2014 Plan and under outstanding awards, and the exercise price of outstanding awards, will be adjusted to 
reflect certain changes in capitalization. In the event of a corporate transaction (as defined in the 2014 Plan), awards will terminate if not 
assumed. If they are assumed, the awards will fully vest if the holder’s employment is terminated without cause or the holder resigns for 
good reason, in either case within 12 months thereafter.

2017 Employee Share Option Plan 

We maintain the 2017 Plan, pursuant to which we may grant share options. The 2017 Plan became effective on September 13, 2017, and has 
a term of ten years. Awards under the 2017 Plan may be granted to our employees. The maximum aggregate number of shares that may be
issued under the plan is 1,000,000 ordinary shares (an equivalent of 200,000 ADSs, each representing five ordinary shares).

The 2017 Plan is administered by our Board, which has the authority to determine the individuals to whom awards may be granted and the 
terms of such awards; and to construe and interpret the terms of the 2017 Plan and awards granted thereunder.

The number of shares under the 2017 Plan and under outstanding awards, and the exercise price of outstanding awards, will be adjusted to 
reflect certain changes in capitalization. In the event of a corporate transaction (as defined in the 2017 Plan), awards will terminate if not 
assumed. If they are assumed, the awards will vest if the holder’s employment is terminated without cause or the holder resigns, in either case 
within 12 months thereafter. In the event of a change in control (as defined in the 2017 Plan) that is not a corporate transaction, awards will 
fully vest if the holder’s employment is terminated without cause or the holder resigns, in either case within 12 months thereafter.

2020 EIP

We maintain the 2020 EIP, pursuant to which we may grant share options. The 2020 EIP became effective on December 15, 2020, and has a 
term of ten years. Awards under the 2020 EIP may be granted to our employees and also non-executive officers. 

The 2020 EIP is administered by the Board, which may delegate its duties and responsibilities to one or more committees of our directors 
and/or officers (referred to as the “Plan Administrator”), subject to certain limitations imposed under the 2020 EIP, and other applicable laws 
and stock exchange rules. The Plan Administrator has the authority to take all actions and make all determinations under the 2020 EIP, to 
interpret  the  2020  EIP  and  award  agreements  and  to  adopt,  amend  and  repeal  rules  for  the  administration  of  the  2020  EIP  as  it  deems 
advisable. The Plan Administrator also has the authority to determine which eligible service providers receive awards, grant awards, set the 
terms and conditions of all awards under the 2020 EIP, including any vesting and vesting acceleration provisions, subject to the conditions 
and limitations in the 2020 EIP.

The maximum number of ordinary shares that may be issued under the 2020 EIP is 20,676,974 ordinary shares (an equivalent of 4,135,394 
ADSs, each representing five ordinary shares). No more than 62,030,922 ordinary shares (an equivalent of 12,406,184 ADSs) may be issued 
under the 2020 EIP upon the exercise of incentive stock options. In addition, the number of ordinary shares reserved for issuance under the 
2020 EIP will automatically increase on January 1 of each year, commencing on January 1, 2022 and ending on (and including) January 1, 
2030,  in  an  amount  equal  to  4%  of  the  total  number  of  ordinary  shares  outstanding  on  December  31  of  the  preceding  calendar  year.  The 
Board may act prior to January 1 of a given year to provide that there will be no increase for such year or that the increase for such year will 
be a lesser number of ordinary shares. 

In  connection  with  the  approval  of  the  2020  EIP,  the  Board  determined  that  there  will  be  no  increase  for  January  1,  2021.  The  Board 
determined that there will be an increase of 13,948,935 ordinary shares (an equivalent of 2,789,787 ADS), which is an amount equal to 4% of 
the total outstanding ordinary shares as of December 31, 2021 and December 31, 2022, of which 8,875,745 ordinary shares (an equivalent of 
1,775,149 ADS) and 10,180,640 ordinary shares (an equivalent of 2,036,128 ADS) were granted on January 1, 2022 and January 1, 2023, 
respectively. 

If an award under the 2020 EIP expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, cancelled without having been 
fully exercised, forfeited or is withheld to satisfy a tax withholding obligation in connection with an award or to satisfy a purchase or exercise 
price of an award, any unused shares subject to the award will, as applicable, become or again be available for new grants under the 2020 
EIP.

98

Awards granted under the 2020 EIP in substitution for any options or other equity or equity-based awards granted by an entity before the 
entity’s merger or consolidation with us or our acquisition of the entity’s property or stock will not reduce the number of ordinary shares 
available for grant under the 2020 EIP, but will count against the maximum number of ordinary shares that may be issued upon the exercise 
of incentive stock options.

References in this summary to ordinary shares include an equivalent number of ADSs on the basis of the ADS-to-ordinary shares ratio in 
effect prior to the ADS Ratio Change. 

2017, 2018 and 2019 SMT LTIPs

We maintain the 2017, 2018 and 2019 LTIPs, pursuant to which we may grant bonus entitlement unit awards. The 2017 LTIP, 2018 LTIP and 
2019 LTIP became effective on August 23, 2017, July 30, 2018, and July 30, 2019, respectively, and each has a term of ten years. Awards 
under each LTIP may be granted to our employees. All of the awards granted in 2017, 2018 and 2019 were granted to our executive officers.

Each LTIP is administered by the members of the remuneration committee, which committee has the authority to: determine the individuals 
to whom unit awards may be granted and the terms of such unit awards; amend the terms of any outstanding unit award, provided that the 
consent of the grantee is required where the grantee’s rights would be adversely affected; construe and interpret the terms of each LTIP and 
unit awards granted thereunder; and take such other action, not inconsistent with the terms of each LTIP, as it deems appropriate.

Upon vesting and redemption, each unit award is converted into a cash payment equal to the number of units multiplied by the per-share fair 
market value of our ordinary shares on the day following our receipt of a redemption notice, up to a cap of five times the base value of the 
unit as set forth in the grantee’s award agreement. Redemption occurs automatically upon termination of employment and upon the per-share 
fair market value exceeding five times the base value of the unit award, to the extent not previously redeemed.

99

The terms of awards will be adjusted to reflect certain changes in capitalization. In the event of a corporate transaction (as defined in each 
LTIP),  awards  will  terminate  if  not  assumed.  If  they  are  assumed,  the  awards  will  vest  and  be  redeemed  if  the  holder’s  employment  is 
terminated without cause or the holder resigns for good reason, in either case within 12 months thereafter. In the event of a change in control 
(as defined in each LTIP) that is not a corporate transaction, awards will fully vest if the holder’s employment is terminated without cause or 
the holder resigns for good reason, in either case within 12 months thereafter.

Insurance and Indemnification

We are empowered by our Articles to indemnify our directors against any liability they incur by reason of their directorship. We maintain 
directors’  and  officers’  insurance  to  insure  such  persons  against  certain  liabilities.  In  addition,  our  employment  agreements  with  our 
executive officers provide for indemnification. We have entered into an indemnification agreement with each of our directors and executive 
officers.

In  addition  to  such  indemnification,  we  provide  our  directors  and  executive  officers  with  directors’  and  officers’  liability  insurance  as 
permitted by our Articles.

Insofar  as  indemnification  of  liabilities  arising  under  the  Securities  Act  may  be  permitted  to  our  board,  executive  officers,  or  persons 
controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against 
public policy as expressed in the Securities Act and is therefore unenforceable.

C.

Board practices. 

Composition of our Board

As a foreign private issuer, under the listing requirements and rules of the Nasdaq Capital Market, we are not required to have independent 
directors on our Board, except to the extent that our audit committee is required to consist of independent directors. Nevertheless, our Board 
has undertaken a review of the independence of the directors and considered whether any director has a material relationship with us that 
could  compromise  his  or  her  ability  to  exercise  independent  judgment  in  carrying  out  his  or  her  responsibilities.  Based  upon  information 
requested  from,  and  provided  by,  each  director  concerning  such  director’s  background,  employment  and  affiliations,  including  family 
relationships,  our  Board  determined  that  all  of  our  directors,  except  for  Dr.  Firth,  qualify  as  “independent  directors”  as  defined  under 
applicable rules of the Nasdaq Capital Market and the independence requirements contemplated by Rule 10A-3 under the Exchange Act. In 
making these determinations, our Board considered the current and prior relationships that each non-employee director has with our company 
and all other facts and circumstances that our Board deemed relevant in determining their independence, including the beneficial ownership 
of our securities by each non-employee director and his or her affiliated entities (if any).

100

 
Board Diversity

As a foreign private issuer with five or fewer board members, under the listing requirements and rules of the Nasdaq Capital Market, we are 
required to have at least one board member who self-identifies as diverse. The listing requirements definition of diverse includes those who 
self-identify as female, as an underrepresented minority in our home country of Singapore and as a member of the LGBTQ+ community. The 
matrix below describes our board’s diversity statistics:

Under Cayman Islands law, all of our directors owe us fiduciary duties, including a duty of loyalty, a duty to act honestly and a duty to act in 
good faith and in a manner they believe to be in our best interests. Our directors also have a duty to exercise the skill they actually possess 
and such care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to 
us, our directors must ensure compliance with our Articles, as amended and restated from time to time. We have the right to seek damages if 
we suffer loss as a consequence of a duty owed by any of our directors being breached.

Terms of Directors and Executive Officers

Our directors may be appointed by a resolution of our Board, or by an ordinary resolution of our shareholders, pursuant to our amended and 
restated memorandum and articles of association. Each director is elected to serve until the director’s earlier removal by way of: (i) ordinary 
resolution, (ii) his or her bankruptcy or arrangement or composition with his or her creditors, (iii) resignation, (iv) death or mental incapacity; 
or  (v)  notice  addressed  to  him  or  her  and  signed  by  all  of  his  or  her  co-Directors  (not  being  less  than  two  in  number).  Our  amended  and 
restated  memorandum  and  articles  of  association  provides  that  the  authorized  number  of  directors  may  be  changed  only  by  ordinary 
resolution of our shareholders. 

Neither  our  directors  nor  executive  officers  are  subject  to  term  limitations.  Our  officers  are  elected  by  and  serve  at  the  discretion  of  the 
Board.

Committees of our Board

Our  Board  has  four  standing  committees:  an  audit  committee,  a  remuneration  committee,  a  nomination  committee  and  a  research  and 
development committee.

Audit Committee

The  audit  committee,  which  consists  of  Mr.  Howden,  Mr.  Hoffman  and  Dr.  Graham,  assists  the  Board  in  overseeing  our  accounting  and 
financial reporting processes and the audits of our financial statements. Mr. Hoffman serves as chairman of the audit committee. The audit 
committee  consists  exclusively  of  independent  members  of  our  board.  Our  Board  has  determined  that  Mr.  Hoffman  qualifies  as  an  “audit 
committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable 
Nasdaq  rules  and  regulations.  Our  board  has  determined  that  all  of  the  members  of  the  audit  committee  satisfy  the  “independence” 
requirements set forth in Rule 10A-3 under the Exchange Act. The audit committee is governed by a charter that complies with Nasdaq rules.

The audit committee’s responsibilities include:

•

•

•

The adoption of or amendments to the internal control system;

Assessment of the effectiveness of the internal control system;

The  adoption  or  amendment,  of  the  procedures  for  handling  financial  or  business  activities  of  a  material  nature  such  as 
acquisition or disposal of assets, derivatives trading, lending of funds to others and endorsements or guarantees for others;

• Matters in which a director is an interested party;

•

•

•

•

•

•

•

Asset transactions or derivatives trading of a material nature;

Loans of funds, endorsements or provision of guarantees of a material nature;

The offering, issuance or private placement of equity-type securities;

The hiring or dismissal of a certified public accountant or their compensation;

The appointment or discharge of a financial, accounting or internal audit officer;

Annual and semi-annual financial reports; and

Other material matters as may be required by us or by the competent authority.

The audit committee meets as often as one or more members of the audit committee deem necessary.

Remuneration Committee

The  remuneration  committee,  which  consists  of  Mr.  Howden,  Mr.  Hoffman  and  Dr.  Metters,  assists  the  Board  in  determining  executive 
officer compensation. Mr. Howden serves as chairman of the remuneration committee. Under SEC and Nasdaq rules, there are heightened 
independence standards for members of the remuneration committee, including a prohibition against the receipt of any compensation from us 
other  than  standard  board  member  fees.  Although  foreign  private  issuers  are  not  required  to  meet  this  heightened  standard,  all  of  our 
remuneration committee members meet this heightened standard.

The remuneration committee’s responsibilities include:

•

•

•

•

Professionally and objectively evaluate the policies and systems for compensation of the directors, supervisors, and managerial 
officers of us, and submit recommendations to the Board for its reference in decision making;

Establishing and periodically reviewing the annual and long-term performance goals for the directors and managerial officers 
of us and the policies, systems, standards, and structure for their compensation;

Periodically  assessing  the  degree  to  which  performance  goals  for  the  directors  and  managerial  officers  of  us  have  been 
achieved, and setting the types and amounts of their individual compensation; and

Periodically review the charter and propose suggestion for amendments.

102

When performing these responsibilities, the remuneration committee follows the following principles:

•

•

•

•

•

Ensuring that the compensation arrangements of us comply with applicable laws and regulations and are sufficient to recruit 
outstanding talent;

Performance assessments and compensation levels of the directors and managerial officers shall take into account the general 
pay  levels  in  the  industry,  the  time  spent  by  the  individual  and  their  responsibilities,  the  extent  of  goal  achievement,  their 
performance in other positions, and the compensation paid to employees holding equivalent positions in recent years. Also to 
be evaluated are the reasonableness of the correlation between the individual’s performance and our operational performance 
and  future  risk  exposure,  with  respect  to  the  achievement  of  our  short-term  and  long-term  business  goals  and  the  financial 
position;

There  shall  be  no  incentive  for  the  directors  or  managerial  officers  to  pursue  compensation  by  engaging  in  activities  that 
exceed the tolerable risk level;

For directors and senior managerial officers, the percentage of bonuses to be distributed based on their short-term performance 
and the time for payment of any variable compensation shall be decided with regard to the characteristics of the industry and 
the nature of our business; and

No  member  of  the  committee  may  participate  in  discussion  and  voting  when  the  committee  is  deciding  on  that  member’s 
individual compensation.

The  remuneration  committee  submits  its  recommendations  regarding  the  above  for  deliberation  to  the  board.  When  deliberating  the 
recommendation  of  the  remuneration  committee,  the  board  must  give  comprehensive  consideration  to  matters  including  the  amounts  of 
remuneration, payment methods, and the potential future risk facing our company. If the board would like to decline to adopt, or would like 
to modify, a recommendation of the remuneration committee, the consent of a majority of the directors in attendance at a meeting attended by 
two-thirds  or  more  of  the  entire  board  is  required,  and  the  board  in  its  resolution  must  provide  its  comprehensive  consideration  and  must 
specifically  explain  whether  the  remuneration  passed  by  it  exceeds  in  any  way  the  remuneration  recommended  by  the  remuneration 
committee.

Nomination Committee

The nomination committee, which consists of Mr. Howden, Dr. Graham and Dr. Metters assists the Board in selecting and approving director 
candidates to serve on the board. Under SEC and Nasdaq rules, director nominees must either be selected, or recommended for the board’s 
selection, either by independent directors constituting a majority of the board’s independent directors in a vote in which only independent 
directors participate, or by a  nomination  committee  comprised  solely  of  independent  directors.  Foreign  private  issuers  are  not  required  to 
have independent director oversight of director nominations. However, our nomination committee consists entirely of independent directors.

The nomination committee’s responsibilities include:

•

•

•

•

•

Reviewing and assessing the composition of the Board;

Identifying appropriate director candidates and independent director candidates;

Reviewing  the  qualifications  and  suitability  of  each  director  candidate  and  independent  director  candidate  identified  by  the 
committee;

Submitting director and independent director recommendations to the Board for consideration; and

Conducting all other necessary actions to facilitate the selection and approval of director candidates and independent director 
candidates by the board.

The nomination committee submits its recommendations regarding the above for deliberation to the board. When deliberating with respect to 
the  recommendation  of  the  nomination  committee,  the  board  must  give  comprehensive  consideration  to  matters  including  the  current 
composition  of  the  board,  the  qualifications  of  director  candidates,  the  overall  diversity  of  the  board  and  the  need  for  refreshing.  The 
nomination committee meets as often as one or more members of the nomination committee deem necessary.

103

Research and Development Committee

The research and development committee, which consists of Dr. Firth, Dr. Graham and Dr. Metters assists the board with the oversight of the 
Company’s portfolio and clinical development strategy, and makes recommendations to the board as needed. The research and development 
committee consists of at least three and up to five members. Members of the research and development committee are elected for a one-year 
term by the members of the board. Election usually takes place at the board meeting following the approval of the audited accounts of the 
previous financial year. One of the members of the research and development committee is designated by the board as Chair of the research 
and development committee.

The research and development committee’s responsibilities include:

•

•

•

•

Reviewing and making recommendations regarding the Company’s portfolio strategy; 

Prioritizing investments into development programs;

Reviewing and making recommendations regarding clinical strategy and trial design for new studies; and

Reviewing scientific findings arising from collaborations and translational studies.

The  research  and  development  committee  meets  as  often  as  one  or  more  members  of  the  research  and  development  committee  deem 
necessary.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics that covers a broad range of matters including the handling of conflicts of interest, 
compliance issues and other corporate policies. Our Code of Business Conduct is applicable to both our directors and employees.

Other Corporate Governance Matters

The Sarbanes-Oxley Act of 2002, as well as related rules subsequently implemented by the SEC, requires foreign private issuers, including 
our  company,  to  comply  with  various  corporate  governance  practices.  In  addition,  Nasdaq  rules  provide  that  foreign  private  issuers  may 
follow home country practice in lieu of the Nasdaq corporate governance standards, subject to certain exceptions and except to the extent that 
such exemptions would be contrary to U.S. federal securities laws.

Because  we  are  a  foreign  private  issuer,  our  members  of  our  Board,  executive  board  members  and  senior  management  are  not  subject  to 
short-swing  profit  and  insider  trading  reporting  obligations  under  section  16  of  the  Exchange  Act.  They  will,  however,  be  subject  to  the 
obligations to report changes in share ownership under section 13 of the Exchange Act and related SEC rules.

Share Ownership. 

For information regarding the share ownership of our directors and executive officers, see “Item 6.B-Compensation” and “Item 7.A-Major 
Shareholders.” 

Item 7. Major Shareholders and Related Party Transactions 

A. Major Shareholders.

The  following  table  sets  forth,  as  of  February  28,  2023,  information  with  respect  to  the  beneficial  ownership  of  our  ordinary  shares  (or 
equivalent number of ADSs) by: 

•

•

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our ordinary shares (or 
equivalent number of ADSs);

each of our executive officers and directors; and

all of our executive officers and directors as a group.

Percentage ownership calculations are based on 408,681,230 ordinary shares outstanding as of February 28, 2023.

As of February 28, 2023, to the best of our knowledge, approximately 337,297,360 ordinary shares (including ordinary shares in the form of
ADSs), or approximately 82.5% of our outstanding ordinary shares, were held by one shareholder of record in the United States, which is 
JPMorgan  Chase  Bank  N.A.,  our  depositary.  The  actual  number  of  holders  is  greater  than  this  number  of  record  holder  and  includes 
beneficial  owners  whose  ordinary  shares  (including  ordinary  shares  in  the  form  of  ADSs)  are  held  in  street  name  by  brokers  and  other 
nominees. This number of holder of record also does not include holders whose shares may be held in trust by other entities.

Except as otherwise indicated, all of the shares reflected in the table are ordinary shares and all persons listed below have sole voting and 
investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information is 
not necessarily indicative of beneficial ownership for any other purpose. The table has been prepared based solely on information supplied to 
us by the beneficial owner or included public documents filed by, or on behalf of, the beneficial owner with the SEC. None of our major 
shareholders have different voting rights with respect to their ordinary shares. We have set forth below information known to us regarding 
any significant change in the percentage ownership of our ordinary shares by any major shareholders during the past three years.

(1) Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess 
sole  or  shared  voting  power  or  investment  power  with  respect  to  those  securities  and  include  securities  issuable  upon  the  exercise  of  options  or  warrants  that  are 
immediately  exercisable  or  exercisable  within  60  days  of  February  28,  2023.  In  computing  the  number  of  ordinary  shares  beneficially  owned  by  a  person  and  the 
percentage ownership of such person, we deemed ordinary shares issuable upon the exercise of options or warrants as beneficially owned by such selling person to the 
extent such options or warrants are exercisable within 60 days of February 28, 2023. We did not deem such ordinary shares outstanding, however, for the purpose of 
computing the percentage ownership of any other person.

(2) On March 13, 2023, we effected a change to the ratio of our ADSs to our ordinary shares from one ADS representing five ordinary shares to one ADS representing 

twenty-five ordinary shares (the ADS Ratio Change). This numbers in this column do not give retroactive effect to the ADS Ratio Change.

in  the  aggregate  is  limited  by  beneficial  ownership  limitations  applicable  to  the  exercise  of  the  Pre-Funded  Warrants  and  Tranche  Warrants  held  by  the  BVF 
Investment Entities, which limit the number of shares the BVF Investment Entities can beneficially own after the exercise of the Pre-Funded Warrants and Tranche 
Warrants  to  a  maximum  of  9.99%  of  our  outstanding  ordinary  shares  and  as  a  result  of  such  limitations,  the  number  of  shares  beneficially  owned  by  the  BVF 
Investment Entities listed above under the column “Number of Ordinary Shares Beneficially Owned” does not include an aggregate of 132,997,475 ordinary shares

included elsewhere in this Annual Report for further details. These loans were repaid in 2021.

2023 Private Placement 

On February 24, 2023, we entered into a Unit Purchase Agreement (the Purchase Agreement), with fund entities affiliated with BVF Partners 
L.P. (collectively, BVF), Tang Capital Partners, LP, a greater than 5% shareholder, and the other purchasers named therein (collectively, the 
Purchasers), pursuant to which we agreed to sell to the Purchasers, in a private placement offering, an aggregate of (i) 112,359,550 ordinary 
shares,  which  includes  (ii)  pre-funded  warrants  exercisable  for  ordinary  shares  (Pre-Funded  Warrants),  to  purchase  five  ordinary  shares, 
represented by our ADSs, at a purchase price of $0.178 per ordinary share (or the equivalent of $0.89 per ADS) and $0.8895 per Pre-Funded 
Warrant  (the  2023  Private  Placement).  The  2023  Private  Placement  closed  on  February  27,  2023  and  resulted  in  gross  proceeds  to  us  of 
approximately $20.0 million. 

As  part  of  the  2023  Private  Placement,  the  Purchasers  also  received  two  tranches  of  warrants  exercisable  in  the  aggregate  for  up  to 
55,309,112 ADSs (or Pre-Funded Warrants exercisable for ADSs). The first tranche of warrants is comprised (i) 50% of warrants that are 
exercisable upon issuance and until 60 days after the public announcement of our topline data from our TREK-AD Phase 2b clinical trial
investigating  eblasakimab  in  atopic  dermatitis  (the  eblasakimab  announcement)  at  an  exercise  price  of  $1.30  per  ADS,  and  (ii)  50%  of 
warrants which can only be exercised within 60 days after the eblasakimab announcement at an exercise price based on the higher of $1.30 
and a 50% discount to the ADSs’ ten-day volume‐weighted average price (VWAP) measured across a specified period after the eblasakimab 
announcement. The second tranche of warrants is similarly comprised (i) 50% of warrants that are exercisable upon issuance until 60 days 
after  the  public  announcement  of  topline  interim  data  from  our  planned  Phase  2  proof  of  concept  trial  investigating  farudodstat  (the 
farudodstat announcement) at an exercise price of $1.63 per ADS, and (ii) 50% of warrants which can only be exercised within 60 days after 
the farudodstat announcement at an exercise price based on the higher of $1.63 and a 50% discount to the ADS VWAP measured across a 
specified period after the farudodstat announcement (collectively, the Tranche Warrants). The Tranche Warrants have a term of five years and 
include  a  mandatory  exercise  provision,  subject  to  the  satisfaction  of  certain  pre-specified  conditions.  If  all  Tranche  Warrants  are  fully-
exercised we would receive an additional $80.0 million in gross proceeds.

Pursuant to the Purchase Agreement, we granted BVF the right to nominate one individual to our Board and are required to recommend to 
our shareholders to elect such nominee until such time that BVF retains beneficial ownership of less than 9.9% of the issued and outstanding 
ordinary shares (including any Pre-Funded Warrants BVF holds as if fully exercised).

Agreements with Our Executive Officers and Directors

We  have  entered  into  employment  agreements  with  our  executive  officers  and  director  compensation  agreements  with  our  non-executive 
directors.  These  agreements  contain  customary  provisions  and  representations,  including  confidentiality,  non-competition  and  non-
solicitation  undertakings  by  the  executive  officers.  However,  the  enforceability  of  the  non-competition  provisions  may  be  limited  under 
applicable law.

Related Party Transaction Policy

We have adopted a related party transaction policy, which requires that certain related party transactions be approved by our Board and audit 
committee. We intend to afford ourselves of the Nasdaq foreign private issuer exemption from the requirement that our audit committee have 
review and oversight over all “related party transactions,” as defined in Item 7.B of Form 20-F. The definition of “related party transactions” 
per our related party transaction policy is not as broad as the definition in Item 7.B of Form 20-F.

Indemnification Agreements

We  have  entered  into,  and  intend  to  continue  to  enter  into,  separate  indemnification  agreements  with  our  directors  and  executive  officers. 
These indemnification agreements provide our directors and executive officers with contractual rights to indemnification and, in some cases, 
expense advancement in any action or proceeding arising out of their services as one of our directors or executive officers or as a director or 
executive officer of any other company or enterprise to which the person provides services at our request.

The purpose of this standard is to specify which financial statements must be included in the document, as well as the periods to be covered, 
the age of the financial statements and other information of a financial nature. 

A.

Consolidated Statements and Other Financial Information. 

Our consolidated financial statements are appended at the end of this Annual Report, starting at page F-1, and are incorporated herein by 
reference. 

Dividend Policy

We have never declared or paid a dividend, and we do not anticipate declaring or paying dividends in the foreseeable future. In addition, we 
are not permitted to dispose of our assets pursuant to the terms of the K2HV Facility without the prior consent of K2HV except for Permitted 
Transfers (as defined in the K2HV loan agreement). Further the K2HV loan agreement contains terms prohibiting or limiting the amount of 
dividends that may be declared or paid on our ADSs or ordinary shares.

The holders of our ordinary shares are entitled to receive such dividends as may be declared by an ordinary resolution and subject to our 
Articles  and  the  Companies  Act.  Under  Cayman  Islands  law,  dividends  may  be  paid  only  out  of  profits,  which  include  net  earnings  and 
retained  earnings  undistributed  in  prior  years,  and  out  of  share  premium,  a  concept  analogous  to  paid-in  surplus  in  the  United  States.  No 
dividend may be declared and paid unless our directors determine that immediately after the payment, we will be able to satisfy our liabilities 
as they become due in the ordinary course of business and we have funds lawfully available for such purpose. We are not permitted to pay 
any  dividends  or  bonuses  if  (i)  we  do  not  have  earnings  or  (ii)  we  have  not  yet  covered  our  losses.  Our  Articles  set  out  further  detailed 
provisions dealing with how we may fund, create reserves for and pay dividends.

Any dividends will be paid to the custodian of the ADSs that were issued in our public offering and shall be subject to further distribution to 
you as a beneficial owner of the underlying ordinary shares by the custodian. 

Legal Proceedings 

From time to time, we may be involved in legal proceedings or be subject to claims arising out of our operations. We are not currently a party 
to any legal proceedings that in the opinion of our management, would have a material adverse effect on our business.

Ordinary Shares

General

Ordinary Shares. All of our outstanding ordinary shares are fully paid and non-assessable, excluding those ordinary shares that have been 
issued to JPMorgan Chase Bank, N.A., as depositary, which are being held for future sales and issuances of ADSs, if any, under the Sale 
Agreement. Our ordinary shares are issued in registered form and certificates representing the ordinary shares have been issued to  certain 
shareholders, including JPMorgan Chase Bank, N.A. Our shareholders who are nonresidents of the Cayman Islands may freely hold and vote

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. In addition, our 
shareholders  may  declare  dividends  by  ordinary  resolution,  but  no  dividend  shall  exceed  the  amount  recommended  by  our  directors.  Our 
Articles  provide  that  the  directors  may,  before  recommending  or  declaring  any  dividend,  set  aside  out  of  the  funds  legally  available  for 
distribution such sums as they think proper as a reserve or reserves which shall be applicable for meeting contingencies or for equalizing 
dividends or for any other purpose to which those funds may be properly applied. Under the laws of the Cayman Islands, our company may 
pay a dividend out of any of profit, retained earnings or the credit standing in our company’s share premium account, provided that in no 
circumstances may a dividend be paid if this would result in our company being unable to pay its debts as they fall due in the ordinary course 
of business immediately following the date on which the distribution or dividend is paid. 

Voting Rights. Holders of our ordinary shares shall be entitled to one vote per ordinary share. Voting at any shareholders’ meeting is by show 
of hands unless a poll is demanded (before or on the declaration of the result of the show of hands). 

110

 
A poll may be demanded by the chairman of such meeting or any one or more shareholders present in person or by proxy at the meeting. 

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching 
to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast 
attaching  to  the  outstanding  ordinary  shares  at  a  meeting.  A  special  resolution  will  be  required  for  important  matters  such  as  a  change  of 
name, making changes to our Articles or approving a merger. Holders of the ordinary shares may, among other things, subdivide, consolidate 
or increase our share capital by ordinary resolution. 

General Meetings of Shareholders. As a Cayman Islands exempted company, we are not obliged by the Companies Act or our Articles to call 
shareholders’ annual general meetings. 

Shareholders’ general meetings may be convened by a majority of our board of directors. Advance written notice of at least seven calendar 
days (counting from the date service is deemed to take place as provided in our Articles) is required for the convening of any general meeting 
of  our  shareholders.  A  quorum  required  for  any  general  meeting  of  shareholders  consists  of  at  least  one  shareholder  present  or  by  proxy, 
representing at least a majority of our paid up voting share capital. 

The Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with 
any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our 
Articles provide general meetings shall also be convened on the requisition in writing of any Shareholder or Shareholders entitled to attend 
and vote at our general meetings holding at least ten percent of the paid up voting share capital deposited at the Office specifying the objects 
of the meeting by notice given no later than 21 days from the date of deposit of the requisition duly proceed to convene a general meeting to 
be held. 

Transfer of Ordinary Shares. Subject to the restrictions set out below, any of our shareholders may transfer all or any of his or her ordinary 
shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors. Our board of directors 
may determine to decline to register any transfer of shares for any reason. 

Liquidation. On the winding up of our company, if the assets available for distribution amongst our shareholders shall be more than sufficient 
to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in 
proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in 
respect  of  which  there  are  monies  due,  of  all  monies  payable  to  our  company  for  unpaid  calls  or  otherwise.  If  our  assets  available  for 
distribution  are  insufficient  to  repay  the  whole  of  the  share  capital,  the  assets  will  be  distributed  so  that  the  losses  are  borne  by  our 
shareholders in proportion to the par value of the shares held by them. 

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid 
on their shares in a notice served to such shareholders at least 14 days prior to the specified time and place of payment. The shares that have 
been called upon and remain unpaid are subject to forfeiture. 

Redemption, Repurchase and Surrender of Shares. We may issue shares on terms that such shares are subject to redemption, at our option or 
at the option of the holders of these shares, on such terms and in such manner as may be determined by our board of directors. We may also 
repurchase any of our shares on such terms and in such manner as have been approved by our board of directors and agreed with the relevant 
shareholder. Under the Companies Act, the redemption or repurchase of any share may be paid out of our profits, retained earnings or out of 
the proceeds of a new issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium 
account  and  capital  redemption  reserve)  if  our  company  can,  immediately  following  such  payment,  pay  its  debts  as  they  fall  due  in  the 
ordinary course of business. In addition, under the Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid 
up, (b) if such redemption or repurchase would result in there being no shares outstanding or (c) if the company has commenced liquidation. 
In addition, our company may accept the surrender of any fully paid share for no consideration. 

111

 
Variations of Rights of Shares. If at any time our share capital is divided into different classes (and as otherwise determined by our board of 
directors)  the  rights  attached  to  any  such  class  may,  subject  to  any  rights  or  restrictions  for  the  time  being  attached  to  any  class  only  be 
materially  adversely  varied  or  abrogated  with  the  consent  in  writing  of  the  holders  of  not  less  than  two-thirds  of  the  issued  shares  of  the 
relevant class, or with the sanction of a resolution passed at a separate meeting of the holders of the shares of such class by a majority of two-
thirds of the votes cast at such a meeting. The board of directors may vary the rights attaching to any class without the consent or approval of 
shareholders provided that the rights will not, in the determination of the board of directors, be materially adversely varied or abrogated by 
such action. 

Issuance of Additional Shares. Our Articles authorize our board of directors to issue additional ordinary shares from time to time as our board 
of directors shall determine, to the extent of available authorized but unissued shares. 

Our Articles also authorize our board of directors to establish from time to time one or more series of preferred shares with the approval of 
the board of directors and with the approval of a special resolution and to determine, with respect to any series of preference shares, the terms 
and rights of that series, including the: 

•

•

•

•

Order, fixed amount or fixed ratio of allocation of dividends and other distributions on preferred shares; 

Order, fixed amount or fixed ratio of allocation of the assets available for distribution on a liquidation of the Company; 

Order of or restriction on the voting rights (including declaring no voting rights whatsoever) of preferred shareholders; 

Other matters concerning rights and obligations incidental to preferred shares; and 

• Method  by  which  the  Company  is  authorized  or  compelled  to  redeem  the  preferred  shares,  or  a  statement  that  redemption

rights shall not apply. 

Prior  to  the  issuance  of  any  preferred  shares,  the  Articles  shall  be  amended  to  set  forth  the  rights  and  obligations  of  the  preferred  shares. 
Issuance of these shares may dilute the voting power of holders of ordinary shares. 

Inspection of Books and Records. Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain 
copies of our corporate records (except for the memorandum and articles of association of our company, any special resolutions passed by 
our company and the register of mortgages and charges of our company). However, we will provide our shareholders with annual audited 
financial statements.

Anti-Takeover  Provisions.  Some  provisions  of  our  Articles  may  discourage,  delay  or  prevent  a  change  of  control  of  our  company  or 
management that shareholders may consider favorable, including provisions that: 

•

•

Authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, 
privileges and restrictions of such preference shares; and 

Limit the ability of shareholders to requisition and convene general meetings of shareholders. 

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our Articles for a proper 
purpose and for what they believe in good faith to be in the best interests of our company. 

Exempted  Company.  We  are  an  exempted  company  incorporated  with  limited  liability  under  the  Companies  Act.  The  Companies  Act 
distinguishes  between  ordinary  resident  companies  and  exempted  companies.  Any  company  that  is  registered  in  the  Cayman  Islands  but 
conducts  business  mainly  outside  of  the  Cayman  Islands  may  apply  to  be  registered  as  an  exempted  company.  The  requirements  for  an 
exempted company are essentially the same as for an ordinary company except that an exempted company: 

•

•

•

Does not have to file an annual return of its shareholders with the Registrar of Companies; 

Is not required to open its register of members for inspection; 

Does not have to hold an annual general meeting; 

• May issue negotiable or bearer shares or shares with no par value; 

• May obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in 

the first instance); 

• May register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands; 

112

• May register as a limited duration company; and 

• May register as a segregated portfolio company. 

“Limited  liability”  means  that  the  liability  of  each  shareholder  is  limited  to  the  amount  unpaid  by  the  shareholder  on  the  shares  of  the 
company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper 
purpose or other limited circumstances in which a court may be prepared to pierce or lift the corporate veil). 

K2 Loan Agreement, Warrant and Participation Rights

In  connection  with  the  closing  of  the  Loan  Agreement  with  K2HV,  we  issued  a  warrant  to  purchase  ordinary  shares  (K2  Warrant)  to  K2 
HealthVentures  Equity  Trust  LLC.  The  number  of  ordinary  shares  exercisable  under  the  K2  Warrant  equals  (i)  2.95%  of  the  aggregate 
outstanding principal amount of the term loans funded to us divided by (ii) the warrant price of $0.5257 per share (subject to adjustment as 
provided therein). The K2 Warrant also includes a cashless exercise feature allowing the holder to receive shares underlying the warrant in an 
amount  reduced  by  the  aggregate  exercise  price  that  would  have  been  payable  upon  exercise  of  the  warrant  for  such  shares.  In  addition, 
subject  to  compliance  with  applicable  securities  laws  (including  any  holding  period  requirements),  we  are  required  to  use  commercially 
reasonable efforts to facilitate and take all other actions required to enable the deposit of any or all of the ordinary shares exercisable under 
the Warrant with our depositary for the issuance of American Depositary Shares. The K2 Warrant is exercisable until its expiration on July 
12, 2031. The K2 Warrant also provides for automatic cashless exercise or assumption as a result of certain transactions involving a merger, 
acquisition or sale of the company, as set forth in the K2 Warrant.

The Loan Agreement with K2HV also provides K2 HealthVentures Equity Trust LLC with the right to participate in an aggregate amount of 
up to $5.0 million in any offering of our American Depositary Shares, ordinary shares, common stock, convertible preferred stock or other 
equity  securities  (or  certain  other  convertible  instruments  but  excluding  non-convertible  debt  securities),  but  excluding  any  at-the-market 
offerings or facilities, on the same terms, conditions and pricing afforded to others participating in such offering; provided that with respect to 
any  public  offering,  we  are  required  to  use  commercially  reasonable  efforts  to  provide  K2  HealthVentures  Equity  Trust  LLC  with  the 
opportunity  to  invest  in  each  such  offering  if  it  is  lawful  to  do  so  (or  if  the  offering  is  an  underwritten  public  offering  pursuant  to  a 
registration  statement  under  the  Securities  Act  of  1933,  as  amended,  to  use  commercially  reasonable  efforts  to  cause  the  underwriters  for 
such offering to offer K2 HealthVentures Equity Trust LLC an allocation of securities in such offering).

Preferred Shares

Pursuant to our Articles, we may issue shares with rights which are preferential to those of ordinary shares issued by us with the approval of a 
majority of our board of directors present at a meeting attended by two-thirds or more of the total number of directors and with the approval 
of a special resolution. Our Articles must be amended by special resolution to provide for such preference shares.

Material Differences in Corporate Law

The Companies Act is modeled after the corporate legislation of the United Kingdom but does not follow recent United Kingdom statutory 
enactments,  and  differs  from  laws  applicable  to  United  States  corporations  and  their  shareholders.  Set  forth  below  is  a  summary  of  the 
significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in 
Delaware and their shareholders. 

Title of Organizational 
Documents

Duties of Directors

  Delaware

  Cayman Islands

  Certificate of Incorporation Bylaws

  Memorandum of Association and Articles of 

Association

   Under Delaware law, the business and affairs of a 
corporation are managed by or under the direction 
of its board of directors. In exercising their powers, 
directors are charged with a fiduciary duty of care to 
protect the interests of the corporation and a 
fiduciary duty of loyalty to act in the best interests 
of its shareholders. The duty of care requires that 
directors act in an 

   As a matter of Cayman Islands law, directors of 

Cayman Islands companies owe fiduciary duties to 
their respective companies to, amongst other 
things, act in good faith in their dealings with or on 
behalf of the company and exercise their powers 
and fulfill the duties of their office honestly. Five 
core duties are:

113

 
 
informed and deliberative manner and inform 
themselves, prior to making a business decision, of 
all material information reasonably available to 
them. The duty of care also requires that directors 
exercise care in overseeing and investigating the 
conduct of the corporation’s employees. The duty of 
loyalty may be summarized as the duty to act in 
good faith, not out of self-interest, and in a manner 
which the director reasonably believes to be in the 
best interests of the shareholders.

Limitations on Personal 
Liability of Directors

   Subject to the limitations described below, a 

certificate of incorporation may provide for the 
elimination or limitation of the personal liability of 
a director to the corporation or its shareholders for 
monetary damages for a breach of fiduciary duty as 
a director.

Such provision cannot limit liability for breach of 
loyalty, bad faith, intentional misconduct, unlawful 
payment of dividends or unlawful share purchase or 
redemption. In addition, the certificate of 
incorporation cannot limit liability for any act or 
omission occurring prior to the date when such 
provision becomes effective.

•  a duty to act in good faith in what the directors 
bona fide consider to be the best interests of the 
company (and in this regard, it should be noted 
that the duty is owed to the company and not to 
associate companies, subsidiaries or holding 
companies);

•  a duty not to personally profit from 

opportunities that arise from the office of 
director;

• a duty of trusteeship of the company’s assets;

• a duty to avoid conflicts of interest; and

• a duty to exercise powers for the purpose for 

which such powers were conferred.

A director of a Cayman Islands company also owes 
the company a duty to act with skill, care and 
diligence. It was previously considered that a 
director need not exhibit in the performance of his 
or her duties a greater degree of skill than may 
reasonably be expected from a person of his or her 
knowledge and experience. However, there are 
indications that the courts are moving towards an 
objective standard with regard to the required skill 
and care.

   The Companies Act has no equivalent provision to 
Delaware law regarding the limitation of director’s 
liability. However, as a matter of public policy, 
Cayman Islands law will not allow the limitation 
of a director’s liability to the extent that the 
liability is a consequence of the director 
committing a crime or of the director’s own fraud, 
dishonesty or willful default.

Indemnification of Directors, 
Officers, Agents, and Others

   A corporation has the power to indemnify any 
director, officer, employee, or agent of the 
corporation who was, is, or is threatened to be made 
a party who acted in good faith and in a manner he 
believed to be in the best interests of the 
corporation, and if with respect to a criminal 
proceeding, had no reasonable cause to believe his 
conduct would be unlawful, against amounts 
actually and reasonably incurred.

   Cayman Islands law does not limit the extent to 
which a company’s articles of association may 
provide for indemnification of directors and 
officers, except to the extent any such provision 
may be held by the Cayman Islands courts to be 
contrary to public policy, such as to provide 
indemnification against the consequences of 
committing a crime, or against the indemnified 
person’s own fraud or dishonesty.

Interested Directors

   Under Delaware law, a transaction in which a 

director who has an interest is not void or voidable 
solely because such interested director is present at 
or participates in the meeting that authorizes the 
transaction if: (i) the material facts as to such 
interested 

114

   Our Articles contain a provision that allows the 
director who is in any way, whether directly or 
indirectly, interested in a contract or proposed 
contract with us shall declare the nature of his 
interest at a meeting of the directors. A general 
notice 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
director’s relationship or interests are disclosed or 
are known to the board of directors and the board in 
good faith authorizes the transaction by the 
affirmative vote of a majority of the disinterested 
directors, even though the disinterested directors are 
less than a quorum, (ii) such material facts are 
disclosed or are known to the shareholders entitled 
to vote on such transaction and the transaction is 
specifically approved in good faith by vote of the 
shareholders, or (iii) the transaction is fair as to the 
corporation as of the time it is authorized, approved 
or ratified. Under Delaware law, a director could be 
held liable for any transaction in which such 
director derived an improper personal benefit.

  given to the directors by any director to the effect 

that he is to be regarded as interested in any 
contract or other arrangement which may thereafter 
be made with that company or firm shall be 
deemed a sufficient declaration of interest in 
regard to any contract so made. A director may 
vote in respect of any contract or proposed contract 
or arrangement notwithstanding that he may be 
interested therein and if he does so his vote shall be 
counted and he may be counted in the quorum at 
any meeting of the directors at which any such 
contract or proposed contract or arrangement shall 
come before the meeting for consideration.

Voting Requirements

   The certificate of incorporation may include a 

provision requiring supermajority approval by the 
directors or shareholders for any corporate action.

In addition, under Delaware law, certain business 
combinations involving interested shareholders 
require approval by a supermajority of the non-
interested shareholders.

Voting for Directors

   Under Delaware law, unless otherwise specified in 
the certificate of incorporation or bylaws of the 
corporation, directors shall be elected by a plurality 
of the votes of the shares present in person or 
represented by proxy at the meeting and entitled to 
vote on the election of directors.

115

   For the protection of shareholders, certain matters 
must be approved by special resolution of the 
shareholders as a matter of Cayman Islands law, 
including alteration of the memorandum or articles 
of association, appointment of inspectors to 
examine company affairs, reduction of share 
capital (subject, in relevant circumstances, to court 
approval), change of name, authorization of a plan 
of merger or transfer by way of continuation to 
another jurisdiction or consolidation or voluntary 
winding up of the company.

The Companies Act requires that a special 
resolution be passed by a majority of at least two-
thirds or such higher percentage as set forth in the 
articles of association, of shareholders being 
entitled to vote and do vote in person or by proxy 
at a general meeting, or by unanimous written 
consent of shareholders entitled to vote at a general 
meeting. Our Articles provide that a resolution in 
writing signed by all the shareholders for the time 
being entitled to receive notice of and to attend and 
vote at our general meetings (or being corporations 
by their duly authorized representatives) shall be as 
valid and effective as if the same had been passed 
at a general meeting duly convened and held.

   The Companies Act defines “special resolution” 
only. A company’s articles of association can 
therefore tailor the definition of “ordinary 
resolutions” as a whole, or with respect to specific 
provisions.

Our Articles contain a provision that shareholders 
may by ordinary resolution appoint any person to 
be a director. Further, the directors shall have 
power at any time and from time to time to appoint 
any person to be a director, either as a result of a 
casual vacancy or as an additional director, subject 
to the maximum number (if any) imposed by 
Ordinary Resolution.

 
 
 
 
 
 
 
 
 
 
 
 
 
Cumulative Voting

   No cumulative voting for the election of directors 

unless so provided in the certificate of 
incorporation.

   No cumulative voting for the election of directors 
unless so provided in the articles of association. 
Our Articles do not expressly provide for 
cumulative voting on the election of directors.

Directors’ Powers Regarding 
Bylaws

   The certificate of incorporation may grant the 
directors the power to adopt, amend or repeal 
bylaws.

   The memorandum and articles of association may 
only be amended by a special resolution of the 
shareholders.

Nomination and Removal of 
Directors and Filling 
Vacancies on Board

Mergers and Similar 
Arrangements

   Shareholders may generally nominate directors if 
they comply with advance notice provisions and 
other procedural requirements in company bylaws. 
Holders of a majority of the shares may remove a 
director with or without cause, except in certain 
cases involving a classified board or if the company 
uses cumulative voting. Unless otherwise provided 
for in the certificate of incorporation, directorship 
vacancies are filled by a majority of the directors 
elected or then in office.

  Under Delaware law, with certain exceptions, a 
merger, consolidation, exchange or sale of all or 
substantially all the assets of a corporation must be 
approved by the board of directors and a majority of 
the outstanding shares entitled to vote thereon. 
Under Delaware law, a shareholder of a corporation 
participating in certain major corporate transactions 
may, under certain circumstances, be entitled to 
appraisal rights pursuant to which such shareholder 
may receive cash in the amount of the fair value of 
the shares held by such shareholder (as 

   Nomination and removal of directors and filling of 
board vacancies are governed by the terms of the 
articles of association. 

  The Companies Act provides for the merger or 
consolidation of two or more companies into a 
single entity. The legislation makes a distinction 
between a “consolidation” and a “merger.” In a 
consolidation, a new entity is formed from the 
combination of each participating company, and 
the separate consolidating parties, as a 
consequence, cease to exist and are each stricken 
by the Registrar of Companies. In a merger, one 
company remains as the surviving entity, having in 
effect absorbed the other merging party (with the 
vesting of the undertaking, property and liabilities 
of the other merging party with the surviving 
company) that then ceases to exist.

  determined by a court) in lieu of the consideration 
such shareholder would otherwise receive in the 
transaction. Delaware law also provides that a 
parent corporation, by resolution of its board of 
directors, may merge with any subsidiary, of which 
it owns at least

  Two or more Cayman Islands companies may 

merge or consolidate. Cayman Islands companies 
may also merge or consolidate with foreign 
companies provided that the laws of the foreign 
jurisdiction permit such merger or consolidation.

  90% of each class of capital stock without a vote by 
shareholders of such subsidiary. Upon any such 
merger, dissenting shareholders of the subsidiary 
would have appraisal rights.

  Under the Companies Act, a written plan of merger 
or consolidation shall be approved by the directors 
of each constituent company, which then must be 
authorized by each constituent company by way of 
(i) a special resolution of the members of each 
such constituent company; and (ii) such other 
authorization, if any, as may be specified in such 
constituent company’s articles of association.

Shareholder approval is not required where a 
parent company registered in the Cayman Islands 
seeks to merge with one or more of its subsidiaries 
registered in the Cayman Islands and a copy of the 
plan of merger is given to every member of each 
subsidiary 

116

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
company to be merged unless that member agrees 
otherwise.

  Secured creditors must consent to the merger 
although application can be made to the Grand 
Court of the Cayman Islands for such requirement 
to be waived if such secured creditor does not 
grant its consent to the merger. Where a foreign 
company wishes to merge with a Cayman 
company, consent or approval to the transfer of any 
security interest granted by the foreign company to 
the resulting Cayman entity in the transaction is 
required, unless otherwise released or waived by 
the secured party. If the merger plan is approved, it 
is then filed with the Cayman Islands Registrar of 
Companies along with a declaration by a director 
of each company. The Registrar of Companies will 
then issue a certificate of merger which shall be 
prima facie evidence of compliance with all 
requirements of the Companies Act in respect of 
the merger or consolidation.

  The surviving or consolidated entity remains or 
becomes active while the other company or 
companies are automatically dissolved. Unless the 
shares of such shareholder are publicly listed or 
quoted on the expiry date of the period allowed for 
written notice of dissent to be provided to the 
Company, dissenting shareholders in a merger or 
consolidation of this type are entitled to payment 
of the fair value of their shares if such shareholder 
provides a written objection before the vote on 
such merger or consolidation and subsequently 
provides written notice of their decision to dissent 
within 20 days immediately following written 
notice from the Company to such shareholder of 
the authorization for such merger or consolidation. 
The fair value of the shares will be determined by 
the Cayman Islands court if it cannot be agreed 
among the parties. With respect to shares that are 
listed or quoted, a shareholder shall have similar 
rights only if it is required by the terms of the 
merger or consolidation to accept for such shares 
property other than (i) shares (or depositary 
receipts in respect thereof) in the surviving or 
consolidated company; (ii) listed or quoted shares 
(or depositary receipts in respect thereof) of 
another company; (iii) cash in lieu of any fractions 
of shares or depositary receipts described at (i) and 
(ii); or (iv) any combination of shares, depositary 
receipts or cash described in (i)—(iii).

The plan of merger or consolidation must be filed 
with the Registrar of Companies in the Cayman 
Islands together with a declaration as to the 
solvency of the consolidated or surviving 
company, a 

117

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  declaration as to the assets and liabilities of each 
constituent company and an undertaking that a 
copy of the certificate of merger or consolidation 
will be given to the members and creditors of each 
constituent company and that notification of the 
merger and consolidation will be published in the 
Cayman Islands Gazette. 

Our Articles provide that we may merge or 
consolidate with one or more other companies in 
accordance with the Companies Act with the 
approval of a Special Resolution.

Court approval is not required for a merger or 
consolidation effected in compliance with these 
statutory procedures.

  Cayman companies may also be restructured or 

amalgamated under supervision of the Grand Court 
of the Cayman Islands by way of a court-
sanctioned “scheme of arrangement.” A scheme of 
arrangement is one of several transactional 
mechanisms available in the Cayman Islands for 
achieving a restructuring. Others include share 
capital exchange, merger (as described above), 
asset acquisition or control, through contractual 
arrangements, of an operating business. A scheme 
of arrangement must not be beyond the powers of 
the company, as stated in the constitutional 
documents of the company and also requires the 
approval of a majority, in number, of each class of 
shareholders and creditors with whom the 
arrangement is to be made and who must in 
addition represent three-fourths in value of each 
such class of shareholders or creditors, as the case 
may be, that are present and voting either in person 
or by proxy at the meeting summoned for that 
purpose. The convening of the meetings and 
subsequently the terms of the arrangement must be 
sanctioned by the Grand Court of the Cayman 
Islands. While a dissenting shareholder would have 
the right to express to the Court its view that the 
transaction ought not be approved, the Court can 
be expected to approve the scheme of arrangement 
if it is satisfied that:

118

 
 
 
 
 
 
 
 
 
 
 
•  the statutory provisions as to the required 

majority vote have been met;

• the classes which are required to approve the 
scheme of arrangement have been properly 
constituted, so that the members of such classes 
are properly and fairly represented and the 
statutory majority are acting bona fide without 
coercion of the minority to promote interests 
adverse to those of the class;

•  the meetings held by the company in relation to 
the approval of the scheme of arrangement by 
such classes have been convened and held in 
accordance with any directions given by the 
Court;

• the scheme of arrangement has been properly 

explained to the shareholders or creditors so that 
they have been able to exercise an informed vote 
in respect of the scheme; 

• the scheme of arrangement is one which an 

intelligent and honest man, who is a member of 
the relevant class and properly acting might 
approve.

  When a takeover offer is made and accepted by 
holders of 90% of the shares within four months, 
the offeror may, within a two-month period, 
require the holders of the remaining shares to 
transfer such shares on the terms of the offer. An 
objection may be made to the Grand Court of the 
Cayman Islands but is unlikely to succeed unless 
there is evidence of fraud, bad faith or collusion. If 
the arrangement and reconstruction are thus 
approved, any dissenting shareholders would have 
no rights comparable to appraisal rights, which 
would otherwise ordinarily be available to 
dissenting shareholders of United States 
corporations, providing rights to receive payment 
in cash for the judicially determined value of the 
shares.

Shareholder Suits

   Class actions and derivative actions generally are 
available to shareholders under Delaware law for, 
among other things, breach of fiduciary duty, 
corporate waste and actions not taken in accordance 
with applicable law. In such actions, the court 
generally has discretion to permit the winning party 
to recover attorneys’ fees incurred in connection 
with such action.

Inspection of Corporate 
Records

   Under Delaware law, shareholders of a Delaware 
corporation have the right during normal business 
hours to inspect for any proper purpose, and to 
obtain copies of list(s) of shareholders and other 
books and records of the corporation and its 
subsidiaries, if any, to the extent the books and 
records of such subsidiaries are available to the 
corporation.

Shareholder Proposals

   Unless provided in the corporation’s certificate of 
incorporation or bylaws, Delaware law does not 
include a provision restricting the manner in which 
shareholders may bring business before a meeting.

120

   The rights of shareholders under Cayman Islands 
law are not as extensive as those under Delaware 
law. Class actions are generally not available to 
shareholders under Cayman Islands laws; 
historically, there have not been any reported 
instances of such class actions having been 
successfully brought before the Cayman Islands 
courts. In principle, we will normally be the proper 
plaintiff in any claim based on a breach of duty 
owed to the Company, and a claim against (for 
example) the Company’s officers or directors 
usually may not be brought by a shareholder. A 
derivative action may be brought by a minority 
shareholder in only limited circumstances. In this 
regard, the Cayman Islands courts would ordinarily 
be expected to follow English case law precedent, 
which would permit a shareholder to commence an 
action in the company’s name to remedy a wrong 
done to the company where the act complained of 
cannot be ratified by the shareholders and where 
control of the company by the wrongdoer results in 
the company not pursuing a remedy itself. The 
case law shows that derivative actions have been 
permitted in respect of acts that are beyond the 
company’s corporate power, illegal, where the 
individual rights of the plaintiff shareholder have 
been infringed or are about to be infringed and acts 
that are alleged to constitute a “fraud on the 
minority.”

   Except in respect of the inspection of a Company's 
Register of Directors upon payment of a fee at the 
Registrar of Companies in the Cayman Islands by 
any person, shareholders of a Cayman Islands 
exempted company have no general right under 
Cayman Islands law to inspect or obtain copies of 
a list of shareholders or other corporate records 
(other than the register of mortgages or charges) of 
the company. However, these rights may be 
provided in the company’s articles of association.

   The Companies Act does not provide shareholders 
any right to bring business before a meeting or 
requisition a general meeting. However, these 
rights may be provided in the company’s articles of 
association. Our Articles do provide for these 
rights.

 
 
 
 
 
 
 
 
 
 
 
Approval of Corporate 
Matters by Written Consent

   Delaware law permits shareholders to take action by 
written consent signed by the holders of outstanding 
shares having not less than the minimum number of 
votes that would be necessary to authorize or take 
such action at a meeting of shareholders.

   The Companies Act allows a special resolution to 
be passed in writing if signed by all the voting 
shareholders (if authorized by the articles of 
association).

Our Articles authorize such written consents.

Calling of Special 
Shareholders Meetings

   Delaware law permits the board of directors or any 
person who is authorized under a corporation’s 
certificate of incorporation or bylaws to call a 
special meeting of shareholders.

   The Companies Act does not have provisions 
governing the proceedings of shareholders 
meetings which are usually provided in the articles 
of association.

Our Articles allow for shareholders’ meetings to be 
convened on the requisition in writing of any 
shareholder or shareholders holding at least ten 
percent of the paid up voting share capital. Our 
Articles also provide that, in the event that our 
board of directors does not or cannot convene a 
general meeting upon the duly delivered 
requisition of any shareholder or shareholders (as 
described above), the requisitionists themselves 
may convene the general meeting in the same 
manner, as nearly as possible, as that in which 
general meetings may be convened by the 
Directors, and all reasonable expenses incurred by 
the requisitionists as a result of the failure of the 
Directors to convene the general meeting shall be 
reimbursed to them by us.

C. Material contracts. 

Except as otherwise disclosed in this Annual Report (including the exhibits thereto), we are not currently, and have not been in the last two 
years, party to any material contract, other than contracts entered into in the ordinary course of our business. 

2020 ATM Sale Agreement

We  entered  into  an  Open  Market  Sale  AgreementSM  (the  ATM  Sale  Agreement),  with  Jefferies  LLC  on  October  9,  2020,  subsequently 
amended in September 2022, pursuant to which we may issue and sell ADSs from time to time, through at-the-market offerings under which 
Jefferies LLC will act as sales agent and/or principal.

The ATM Sale Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions 
under which the Company and Jefferies LLC have agreed to indemnify each other against certain liabilities, including liabilities under the
Securities Act. Jefferies LLC and the Company have the right, by giving written notice as specified in the ATM Sale Agreement, to terminate 
the ATM Sale Agreement. 

2021 Underwriting Agreement

We entered into an underwriting agreement with Jefferies LLC and Piper Sandler & Co. as representatives of the underwriters, on March 2, 
2021,  with  respect  to  certain  ADSs  sold  in  our  public  offering.  We  have  agreed  to  indemnify  the  underwriters  against  certain  liabilities, 
including liabilities under the U.S. Securities Act of 1933, as amended, and to contribute to payments the underwriters may be required to 
make in respect of such liabilities.

121

 
 
 
 
 
 
2021 Loan Guaranty and Security Agreement 

In July 2021 we entered into a loan agreement with K2 HealthVentures LLC (K2HV) and certain parties related to K2HV, pursuant to which 
K2HV agreed to provide a four-year loan facility for up to $45 million (the K2HV Facility). The K2HV Facility consists of a $20 million 
initial term loan funded at closing, with the remaining $25 million available in tranches subject to certain terms and conditions. Borrowings 
under the K2HV Facility are secured with a pledge of the borrower’s equity interests in subsidiaries and collateral over all of our cash, goods, 
and  other  personal  property,  with  the  exception  of  (i)  our  registered  intellectual  property  assets,  (ii)  personal  property  to  the  extent  that 
granting of security over any such personal property would constitute a breach of or result in the termination of, or require any consent not 
obtained under, any license, agreement, instrument or other document evidencing or giving rise to such property, or is otherwise prohibited 
by any requirement of law, and (iii) our equity interests in JAGUAHR. Such pledge and collateral may be enforced only if there has been an 
event of default as stipulated in the loan agreement. Borrowings under the K2HV Facility can be used to advance the clinical development of 
eblasakimab, farudodstat, and general corporate purposes. Interest on the loan is computed at a variable annual rate equal to the greater of (i) 
eight and one-quarter of one percent (8.25%), and (ii) the sum of (A) the prime rate, as noted in The Wall Street Journal, Money Rates section 
plus (B) five percent (5%), and is payable on a monthly basis. Amounts outstanding can be voluntarily prepaid. Under the K2HV Facility, we 
may not without the permission of K2HV incur any further indebtedness other than Permitted Indebtedness (as defined in the K2HV loan 
agreement). Under the K2HV Facility, we are subject to customary reporting and restrictive covenants. If an event of default occurs, K2HV 
can terminate the commitment under the K2HV Facility and accelerate all amounts outstanding.   

D.

Exchange Controls.

There  are  no  governmental  laws,  decrees,  regulations  or  other  legislation  in  the  Cayman  Islands  that  may  affect  the  import  or  export  of 
capital, including the availability of cash and cash equivalents for use by us, or that may affect the remittance of dividends, interest, or other 
payments by us to non-resident holders of our ordinary shares or ADSs.

There are no governmental laws, decrees, regulations or other legislation in the ROC that may affect the remittance of dividends, interest, or 
other payments by us to non-resident holders of our ordinary shares or ADSs.

E.

Taxation.

The following is a discussion of the material Cayman Islands, ROC and U.S. federal income tax considerations that may be relevant to an 
investment decision by a potential investor with respect to our ADSs. This summary should not be considered a comprehensive description of 
all the tax considerations that may be relevant to the decisions to acquire ADSs.

Material U.S. Federal Income Tax Considerations for U.S. Holders

The  following  discussion  describes  the  material  U.S.  federal  income  tax  consequences  relating  to  the  ownership  and  disposition  of  our 
ordinary shares or ADSs by U.S. Holders (as defined below). This discussion applies to U.S. Holders that purchase our ADSs and hold such 
ADSs  as  capital  assets  (generally,  property  held  for  investment).  This  discussion  is  based  on  the  U.S.  Internal  Revenue  Code  of  1986  (as 
amended the Code), U.S. Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as in effect 
on the date hereof and all of which are subject to change, possibly with retroactive effect. This discussion does not address all of the U.S. 
federal income tax consequences that may be relevant to specific U.S. Holders in light of their particular circumstances or to U.S. Holders 
subject to special treatment under U.S. federal income tax law (such as certain banks, financial institutions, insurance companies, brokers, 
dealers or traders in securities, commodities, currencies or notional principal contracts or other persons that generally mark their securities to 
market  for  U.S.  federal  income  tax  purposes,  tax-exempt  entities  or  governmental  organizations,  retirement  plans,  regulated  investment 
companies, real estate investment trusts, grantor trusts, certain former citizens or long-term residents of the United States, persons who hold 
our ordinary shares or ADSs as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security,” “wash sale” or other integrated 
investment, persons that have a “functional currency” other than the U.S. dollar, persons that own directly, indirectly or through attribution 
10% or more of the voting power or value of our ordinary shares, corporations that accumulate earnings to avoid U.S. federal income tax, 
entities  or  arrangements  classified  as  partnerships  or  S  corporations  for  U.S.  federal  income  tax  purposes  or  other  pass-through  entities, 
including hybrid entities and disregarded entities, and investors in such entities). In addition, this discussion does not address any U.S. state 
or local or non-U.S. tax consequences or any U.S. federal estate, gift or alternative minimum tax consequences, or the special tax accounting 
rules in Section 451(b) of the Code.

122

As used in this discussion, the term “U.S. Holder” means a beneficial owner of our ordinary shares or ADSs who is, for U.S. federal income 
tax purposes, (1) an individual who is a citizen or resident of the United States, (2) a corporation (or entity treated as a corporation for U.S. 
federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia, (3) 
an estate the income of which is subject to U.S. federal income tax regardless of its source or (4) a trust (x) with respect to which a court 
within  the  United  States  is  able  to  exercise  primary  supervision  over  its  administration  and  one  or  more  United  States  persons  have  the 
authority  to  control  all  of  its  substantial  decisions  or  (y)  that  has  elected  under  applicable  U.S.  Treasury  regulations  to  be  treated  as  a 
domestic trust for U.S. federal income tax purposes.

If  an  entity  or  arrangement  classified  as  a  partnership  for  U.S.  federal  income  tax  purposes  holds  our  ordinary  shares  or  ADSs,  the  U.S. 
federal income tax consequences to a partner relating to an investment in such ordinary shares or ADSs will depend in part upon the activities 
of  such  entity  and  the  status  of  the  particular  partner.  Partnerships  holding  our  ordinary  shares  or  ADSs  and  partners  in  such  partnership 
should consult their own tax advisors regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of our 
ordinary shares or ADSs.

Persons  considering  an  investment  in  our  ADSs  should  consult  their  own  tax  advisors  as  to  the  particular  tax  consequences  applicable  to 
them relating to the purchase, ownership and disposition of our ADSs, including the applicability of U.S. federal, state and local tax laws and 
non-U.S. tax laws.

The  discussion  below  assumes  that  the  representations  contained  in  the  deposit  agreement  are  true  and  that  the  obligations  in  the  deposit 
agreement and any related agreement will be complied with in accordance with their terms. Generally, a holder of an ADS should be treated 
for U.S. federal income tax purposes as holding the ordinary shares represented by the ADS. Accordingly, no gain or loss will be recognized 
upon an exchange of ADSs for the underlying ordinary shares represented by such ADSs. The U.S. Treasury has expressed concerns that 
intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking 
actions that are inconsistent with the beneficial ownership of the underlying security. Accordingly, the creditability of foreign taxes, if any, as 
described  below,  could  be  affected  by  actions  taken  by  intermediaries  in  the  chain  of  ownership  between  the  holders  of  ADSs  and  our 
company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of the underlying ordinary shares.

Passive Foreign Investment Company Consequences

In general, a corporation organized outside the United States will be treated as a passive foreign investment company (PFIC) for any taxable 
year in which either (1) at least 75% of its gross income is “passive income” (PFIC income test), or (2) on average at least 50% of its assets, 
determined on a quarterly basis, are assets that produce passive income or are held for the production of passive income (PFIC asset test). 
Passive  income  for  this  purpose  generally  includes,  among  other  things,  dividends,  interest,  royalties,  rents,  and  gains  from  the  sale  or 
exchange of property that gives rise to passive income. 

Assets that produce or are held for the production of passive income generally include cash, even if held as working capital or raised in a 
public  offering,  marketable  securities,  and  other  assets  that  may  produce  passive  income.  Generally,  in  determining  whether  a  non-U.S. 
corporation is a PFIC, a proportionate share of the income and assets of each corporation in which it owns, directly or indirectly, at least a 
25% interest (by value) is taken into account.

Although PFIC status is determined on an annual basis and generally cannot be determined until the end of the taxable year, based on the 
nature of our current and expected income and the current and expected value and composition of our assets, we believe we were a PFIC for 
the  taxable  year  ended  December  31,  2022.  Because  we  may  hold  a  substantial  amount  of  cash  and  cash  equivalents,  and  because  the 
calculation of the value of our assets may be based in part on the value of ordinary shares, which may fluctuate considerably, we may also be 
a PFIC in future taxable years. Even if we determine that we are not a PFIC for a taxable year, there can be no assurance that the Internal 
Revenue Service (IRS) will agree with our conclusion and that the IRS would not successfully challenge our position. Our status as a PFIC is 
a fact-intensive determination made on an annual basis applying principles and methodologies that are unclear in some respects and subject 
to varying interpretations. In particular, the characterization of our assets as active or passive may depend in part on our current and intended 
future business plans, which are subject to change. The composition of our income and assets is also affected by how, and how quickly, we 
spend the cash we raise in any offering. Accordingly, our U.S. counsel expresses no opinion with respect to our PFIC status in our current 
taxable year or in any prior or future taxable year.

123

If we are a PFIC in any taxable year during which a U.S. Holder owns our ordinary shares or ADSs, the U.S. Holder could be liable for 
additional taxes and interest charges under the “PFIC excess distribution regime” upon (1) a distribution paid during a taxable year that is
greater  than  125%  of  the  average  annual  distributions  paid  in  the  three  preceding  taxable  years,  or,  if  shorter,  the  U.S.  Holder’s  holding 
period  for  our  ordinary  shares  or  ADSs,  and  (2)  any  gain  recognized  on  a  sale,  exchange  or  other  disposition,  including  a  pledge,  of  our 
ordinary shares or ADSs, whether or not we continue to be a PFIC. Under the PFIC excess distribution regime, the tax on such distribution or 
gain  would  be  determined  by  allocating  the  distribution  or  gain  ratably  over  the  U.S.  Holder’s  holding  period  for  our  ordinary  shares  or
ADSs. The amount allocated to the current taxable year (i.e., the year in which the distribution occurs or the gain is recognized) and any year 
prior  to  the  first  taxable  year  in  which  we  are  a  PFIC  will  be  taxed  as  ordinary  income  earned  in  the  current  taxable  year.  The  amount 
allocated to other taxable years will be taxed at the highest marginal rates in effect for individuals or corporations, as applicable, to ordinary 
income for each such taxable year, and an interest charge, generally applicable to underpayments of tax, will be added to the tax.

If we are a PFIC for any year during which a U.S. Holder holds our ordinary shares or ADSs, we must generally continue to be treated as a 
PFIC by that holder for all succeeding years during which the U.S. Holder holds such ordinary shares or ADSs, unless we cease to meet the 
requirements for PFIC status and the U.S. Holder makes a “deemed sale” election with respect to our ordinary shares or ADSs. If the election 
is made, the U.S. Holder will be deemed to sell our ordinary shares or ADSs it holds at their fair market value on the last day of the last 
taxable  year  in  which  we  qualified  as  a  PFIC,  and  any  gain  recognized  from  such  deemed  sale  would  be  taxed  under  the  PFIC  excess 
distribution regime, but any loss would not be recognized. After the deemed sale election, the U.S. Holder’s ordinary shares or ADSs would 
not be treated as shares of a PFIC unless we subsequently become a PFIC.

If  we  are  a  PFIC  for  any  taxable  year  during  which  a  U.S.  Holder  holds  our  ordinary  shares  or  ADSs  and  one  of  our  non-United  States 
subsidiaries is also a PFIC (ie, a lower-tier PFIC), such U.S. Holder would be treated as owning a proportionate amount (by value) of the 
shares of the lower-tier PFIC and would be taxed under the PFIC excess distribution regime on distributions by the lower-tier PFIC and on 
gain from the disposition of shares of the lower-tier PFIC even though such U.S. Holder would not receive the proceeds of those distributions 
or dispositions. Any of our non-United States subsidiaries that have elected to be disregarded as entities separate from us or as partnerships 
for U.S. federal income tax purposes would not be corporations under U.S. federal income tax law and accordingly, cannot be classified as 
lower-tier PFICs. However, non-United States subsidiaries that have not made the election may be classified as a lower-tier PFIC if we are a 
PFIC during your holding period and the subsidiary meets the PFIC income test or PFIC asset test. Each U.S. Holder is advised to consult its 
tax advisors regarding the application of the PFIC rules to any of our non-United States subsidiaries.

If we are a PFIC, a U.S. Holder will not be subject to tax under the PFIC excess distribution regime on distributions or gain recognized on
our ordinary shares or ADSs if a valid “mark-to-market” election is made by the U.S. Holder for our ordinary shares or ADSs. An electing 
U.S. Holder generally would take into account as ordinary income each year, the excess of the fair market value of our ordinary shares or 
ADSs held at the end of such taxable year over the adjusted tax basis of such ordinary shares or ADSs. The U.S. Holder would also take into 
account, as an ordinary loss each year, the excess of the adjusted tax basis of such ordinary shares or ADSs over their fair market value at the 
end of the taxable year, but only to the extent of the excess of amounts previously included in income over ordinary losses deducted as a 
result of the mark-to-market election. The U.S. Holder’s tax basis in our ordinary shares or ADSs would be adjusted to reflect any income or 
loss  recognized  as  a  result  of  the  mark-to-market  election.  Any  gain  from  a  sale,  exchange  or  other  disposition  of  our  ordinary  shares  or 
ADSs  in  any  taxable  year  in  which  we  are  a  PFIC  would  be  treated  as  ordinary  income  and  any  loss  from  such  sale,  exchange  or  other 
disposition  would  be  treated  first  as  ordinary  loss  (to  the  extent  of  any  net  mark-to-market  gains  previously  included  in  income)  and 
thereafter as capital loss. If, after having been a PFIC for a taxable year, we cease to be classified as a PFIC because we no longer meet the 
PFIC income or PFIC asset test, the U.S. Holder would not be required to take into account any latent gain or loss in the manner described 
above and any gain or loss recognized on the sale or exchange of the ordinary shares or ADSs would be classified as a capital gain or loss.

124

A mark-to-market election is available to a U.S. Holder only for “marketable stock.” Generally, stock will be considered marketable stock if 
it is “regularly traded” on a “qualified exchange” within the meaning of applicable U.S. Treasury regulations. A class of stock is regularly 
traded during any calendar year during which such class of stock is traded, other than in de minimis quantities, on at least 15 days during 
each calendar quarter.

In general, a U.S. Holder makes a mark-to-market election by attaching a properly executed IRS Form 8621 to its U.S. federal income tax 
return for the first taxable year to which it wishes the election to apply. 

Our ADSs will be marketable stock as long as they remain listed on The Nasdaq Global Market and are regularly traded. A mark-to-market 
election will not apply to the ordinary shares or ADSs for any taxable year during which we are not a PFIC, but will remain in effect with 
respect  to  any  subsequent  taxable  year  in  which  we  become  a  PFIC.  Such  election  will  not  apply  to  any  of  our  non-U.S.  subsidiaries. 
Accordingly, a U.S. Holder may continue to be subject to tax under the PFIC excess distribution regime with respect to any lower-tier PFICs 
notwithstanding the U.S. Holder’s mark-to-market election for the ordinary shares or ADSs.

The tax consequences that would apply if we are a PFIC would also be different from those described above if a U.S. Holder were able to 
make a valid qualified electing fund (QEF) election. While we will consider providing U.S. Holders with the information necessary for a U.S. 
Holder to make a QEF election, we can provide no assurance that we will do so, in which case such a QEF election would not be available 
for a U.S. Holder.

The U.S. federal income tax rules relating to PFICs are very complex. Prospective U.S. investors are strongly urged to consult their 
own  tax  advisors  with  respect  to  the  impact  of  PFIC  status  on  the  purchase,  ownership  and  disposition  of  our  ADSs,  the 
consequences to them of an investment in a PFIC, any elections available with respect to the ADSs and the IRS information reporting 
obligations with respect to the purchase, ownership and disposition of ADSs of a PFIC.

Distributions

Subject to the discussion above under “—Passive Foreign Investment Company Consequences,” a U.S. Holder that receives a distribution 
with respect to our ordinary shares or ADSs generally will be required to include the gross amount of such distribution in gross income as a 
dividend when actually or constructively received to the extent of the U.S. Holder’s pro rata share of our current and/or accumulated earnings 
and profits (as determined under U.S. federal income tax principles). To the extent a distribution received by a U.S. Holder is not a dividend 
because it exceeds the U.S. Holder’s pro rata share of our current and accumulated earnings and profits, it will be treated first as a tax-free 
return  of  capital  and  reduce  (but  not  below  zero)  the  adjusted  tax  basis  of  the  U.S.  Holder’s  ordinary  shares  or  ADSs.  To  the  extent  the 
distribution exceeds the adjusted tax basis of the U.S. Holder’s ordinary shares or ADSs, the remainder will be taxed as capital gain. Because 
we  may  not  account  for  our  earnings  and  profits  in  accordance  with  U.S.  federal  income  tax  principles,  U.S.  Holders  should  expect  all 
distributions to be reported to them as dividends.

Distributions on our ordinary shares or ADSs that are treated as dividends generally will constitute income from sources outside the United 
States  for  foreign  tax  credit  purposes  and  generally  will  constitute  passive  category  income.  Such  dividends  will  not  be  eligible  for  the 
“dividends  received”  deduction  generally  allowed  to  corporate  shareholders  with  respect  to  dividends  received  from  U.S.  corporations. 
Dividends paid by a “qualified foreign corporation” to certain non-corporate U.S. Holders may be eligible for taxation at a reduced capital 
gains rate if certain requirements are met. Each U.S. Holder is advised to consult its tax advisors regarding the availability of the reduced tax 
rate  on  dividends  to  its  particular  circumstances.  However,  if  we  are  a  PFIC  for  the  taxable  year  in  which  the  dividend  is  paid  or  the 
preceding taxable year (see discussion above under “—Passive Foreign Investment Company Consequences”), we will not be treated as a 
qualified foreign corporation, and therefore the reduced capital gains tax rate described above will not apply.

Dividends will be included in a U.S. Holder’s income on the date of the Depositary’s receipt of the dividend. 

Sale, Exchange or Other Disposition of Our Ordinary Shares or ADSs

Subject  to  the  discussion  above  under  “—Passive  Foreign  Investment  Company  Consequences,”  a  U.S.  Holder  generally  will  recognize 
capital gain or loss for U.S. federal income tax purposes upon the sale, exchange or other disposition of our ordinary shares or ADSs in an 
amount  equal  to  the  difference,  if  any,  between  the  amount  realized  (i.e.,  the  amount  of  cash  plus  the  fair  market  value  of  any  property 
received) on the sale, exchange or other disposition and such U.S. Holder’s adjusted tax basis in the ordinary shares or ADSs. Such capital 
gain or loss generally will be long-term capital gain taxable at a reduced rate for non-corporate U.S. Holders or long-term capital loss if, on 
the date of sale, exchange or other disposition, the ordinary shares or ADSs were held by the U.S. Holder for more than one year. Any capital 
gain of a non-corporate U.S. Holder that is not long-term capital gain is taxed at ordinary income rates. The deductibility of 

125

capital losses is subject to limitations. Any gain or loss recognized from the sale or other disposition of our ordinary shares or ADSs will 
generally be gain or loss from sources within the United States for U.S. foreign tax credit purposes.

Medicare Tax

Certain U.S. Holders that are individuals, estates or trusts and whose income exceeds certain thresholds generally are subject to a 3.8% tax on 
all  or  a  portion  of  their  net  investment  income,  which  may  include  their  gross  dividend  income  and  net  gains  from  the  disposition  of  our 
ordinary  shares  or  ADSs.  If  you  are  a  United  States  person  that  is  an  individual,  estate  or  trust,  you  are  encouraged  to  consult  your  tax 
advisors regarding the applicability of this Medicare tax to your income and gains in respect of your investment in our ordinary shares or 
ADSs.

Information Reporting and Backup Withholding

U.S. Holders may be required to file certain U.S. information reporting returns with the IRS with respect to an investment in our ordinary 
shares  or  ADSs,  including,  among  others,  IRS  Form  8938  (Statement  of  Specified  Foreign  Financial  Assets).  Each  U.S.  Holder  who  is  a 
shareholder of a PFIC must file an annual report on IRS Form 8621 (or any successor form) containing certain information, generally with 
the U.S. Holder’s U.S. federal income tax return for the relevant year. Substantial penalties may be imposed upon a U.S. Holder that fails to 
comply with the required information reporting.

Unless  otherwise  provided  by  the  U.S.  Treasury,  each  U.S.  shareholder  of  a  PFIC  is  required  to  file  an  annual  report  containing  such 
information as the U.S. Treasury may require. A U.S. Holder’s failure to file the annual report will cause the statute of limitations for such 
U.S. Holder’s U.S. federal income tax return to remain open with regard to the items required to be included in such report until three years 
after  the  U.S.  Holder  files  the  annual  report,  and,  unless  such  failure  is  due  to  reasonable  cause  and  not  willful  neglect,  the  statute  of 
limitations for the U.S. Holder’s entire U.S. federal income tax return will remain open during such period. 

Dividends on and proceeds from the sale or other disposition of our ADSs may be reported to the IRS unless the U.S. Holder establishes a
basis  for  exemption.  Backup  withholding  may  apply  to  amounts  subject  to  reporting  if  the  holder  (1)  fails  to  provide  an  accurate  U.S. 
taxpayer  identification  number  or  otherwise  establish  a  basis  for  exemption,  or  (2)  is  described  in  certain  other  categories  of  persons. 
However, U.S. Holders that are corporations generally are excluded from these information reporting and backup withholding tax rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund 
or a credit against a U.S. Holder’s U.S. federal income tax liability if the required information is furnished by the U.S. Holder on a timely 
basis to the IRS.

U.S. Holders should consult their own tax advisors regarding the backup withholding tax and information reporting rules.

EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES 
TO  IT  OF  AN  INVESTMENT  IN  OUR  ADSs  OR  ORDINARY  SHARES  IN  LIGHT  OF  THE  INVESTOR’S  OWN 
CIRCUMSTANCES.

Cayman Taxation

Prospective investors should consult their professional advisers on the possible tax consequences of buying, holding or selling any ADSs or 
ordinary shares under the laws of their country of citizenship, residence or domicile.

The  following  is  a  discussion  on  certain  Cayman  Islands  income  tax  consequences  of  an  investment  in  the  ADSs  or  ordinary  shares.  The 
discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does 
not consider any investor’s particular circumstances, and does not consider tax consequences other than those arising under Cayman Islands 
law.

No stamp duty, capital duty, registration or other issue or documentary taxes are payable in the Cayman Islands on the creation, issuance or 
delivery of the ADSs or ordinary shares. The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate 
duty, inheritance tax or gift tax. There are currently no Cayman Islands’ taxes or duties of any nature on gains realized on a sale, exchange, 
conversion, transfer or redemption of the ADSs or ordinary shares. Payments of dividends and capital in respect of the ADSs or ordinary 
shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of interest and principal or a 
dividend or capital to any holder of the ADSs or ordinary shares, nor will gains derived from the disposal of the ADSs or ordinary shares be 
subject to Cayman Islands income or corporation tax as the Cayman Islands currently have no form of income or corporation taxes.

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability and, as such, have applied for and 
have received an undertaking from the Governor of the Cayman Islands that no law enacted in the Cayman Islands during the period of 30 
years from 3 January 2018, being the date of the undertaking imposing any tax to be levied on profits, income, gains or appreciation shall 
apply to us or our operations and no such tax or any tax in the nature of estate duty or inheritance tax shall be payable (directly or by way of 
withholding) on the ADSs or ordinary shares, debentures or other obligations of ours.

Documents on Display. 

We are subject to the informational requirements of the Exchange Act and are required to file reports and other information with the SEC. 
The  SEC  maintains  a  website  at  www.sec.gov  that  contains  reports,  proxy  and  information  statements,  and  other  information  regarding 
registrants that make electronic filings with SEC using its EDGAR system. 

We are a “foreign private issuer” as such term is defined in Rule 405 under the Securities Act, and are not subject to the same requirements 
that are imposed upon U.S. domestic issuers by the SEC. Under the Exchange Act, we are subject to reporting obligations that, in certain 
respects, are less detailed and less frequent than those of U.S. domestic reporting companies. As a result, we do not file the same reports that 
a U.S. domestic issuer would file with the SEC. We also make available on our website’s investor relations page, free of charge, our annual 
report and the text of our reports on Form 6-K, including any amendments to these reports, as well as certain other SEC filings, as soon as 
reasonably  practicable  after  they  are  electronically  filed  with  or  furnished  to  the  SEC.  The  address  for  our  investor  relations  page  is

Item 11.   Quantitative and Qualitative Disclosures about Market Risk 

Our financial risk management objective is to monitor and manage the financial risks relating to our operations. These risks include risks in 
financial markets (including currency risk, interest rate risk and other price risk), credit risk and liquidity risk. In order to minimize the effect 
of  financial  risks,  we  devote  time  and  resources  to  identifying  and  evaluating  the  uncertainty  of  the  financial  market  to  mitigate  risk 
exposures. 

Our activities expose us primarily to risks of changes in foreign currency exchange rates, interest rates and other price risks.

Effects of Inflation

Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation and changing prices had a 
significant impact on our results of operations for any periods presented herein. While we are seeing, and expect to continue to see, record 
inflation  due  to,  among  other  things,  the  COVID-19  pandemic  and  other  geopolitical  and  macroeconomic  events,  such  as  the  ongoing 
military conflict between Ukraine and Russia and related sanctions, and bank failures, as of December 31, 2022, we do not expect anticipated 
changes in inflation to have a material effect on our business, financial condition or results of operations for future reporting periods.

A.

Foreign Exchange Risk.

We have foreign currency transactions, which expose us to foreign currency risks. The significant financial assets and liabilities denominated 
in foreign currencies as of December 31, 2021 were as follows:

management’s assessment of the reasonably possible change in foreign exchange rates. Based on outstanding foreign currency-denominated

million increase to net (loss)/gain and (decrease)/increase to equity.

B.

Interest Rate Risk.

We are exposed to interest rate risk because we have borrowed funds at both fixed and floating interest rates. The risk is managed by us by 
maintaining an appropriate mix of fixed and floating rate borrowings.

The  sensitivity  analysis  below  is  determined  based  on  our  exposure  to  interest  rates  for  fixed  rate  borrowings  at  the  end  of  the  reporting 
period, and is prepared assuming that the amounts of liabilities outstanding at the end of the reporting period are outstanding for the whole 
year. A 100-basis point increase or decrease is used when reporting interest rate risk internally to key management personnel and represents 
management’s assessment of the reasonably possible change in interest rates.

If interest rates had been 100 basis points higher and all other variables were held constant, our pre-tax loss for the years ended December 31, 
2021 and 2022 would have increased around by $0.31 million and $0.07 million, respectively.

D.

American Depositary Shares. 

JPMorgan  Chase  Bank,  N.A.  (JPMorgan),  as  depositary  will  issue  the  ADSs  in  connection  with  an  offering.  Each  ADS  will  represent  an 
ownership interest in a designated number of our ordinary shares which we will deposit with the depositary or the custodian, as agent of the 
depositary, under the deposit agreement among ourselves, the depositary and yourself as an ADR holder. In the future, each ADS will also 
represent  any  securities,  cash  or  other  property  deposited  with  the  depositary  but  which  have  not  distributed  directly  to  you.  Unless 
certificated ADRs are specifically requested by you, all ADSs will be issued on the books of our depositary in book-entry form and periodic 
statements will be mailed to you which reflect your ownership interest in such ADSs. In our description, references to ADRs shall include the 
statements you will receive which reflect your ownership of ADSs. 

The depositary’s office is located at 383 Madison Avenue, Floor 11, New York, NY, 10179. 

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an 
ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. 
If  you  hold  the  ADSs  through  your  broker  or  financial  institution  nominee,  you  must  rely  on  the  procedures  of  such  broker  or  financial 
institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find 
out what those procedures are. 

As an ADR holder, we will not treat you as a shareholder of ours and you will not have any direct shareholder rights. Because the depositary 
or its nominee will be the shareholder of record for the ordinary shares represented by all outstanding ADSs, shareholder rights rest with such 
record holder. Your rights are those of an ADR holder. Such rights derive from the terms of the deposit agreement to be entered into among 
us, the depositary and all holders from time to time of ADRs issued under the deposit agreement. The obligations of the depositary and its 
agents are also set out in the deposit agreement. Because the depositary or its nominee will actually be the registered owner of the ordinary 
shares, you must rely on it to exercise the rights of a shareholder on your behalf. The deposit agreement and the ADSs are governed by New 
York law. However, our obligations to the holders of ordinary shares will continue to be governed by the Cayman Islands, which may be 
different  from  the  laws  of  the  United  States.  Under  the  deposit  agreement,  as  an  ADR  holder,  you  agree  that  any  legal  suit,  action  or 
proceeding  against  or  involving  us  or  the  depositary,  arising  out  of  or  based  upon  the  deposit  agreement,  the  ADSs,  the  ADRs  or  the 
transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and you irrevocably waive any 
objection which you may have to the laying of venue of any such proceeding and irrevocably submit to the exclusive jurisdiction of such 
courts in any such suit, action or proceeding. 

The  following  is  a  summary  of  what  we  believe  to  be  the  material  terms  of  the  deposit  agreement.  Notwithstanding  this,  because  it  is  a 
summary, it may not contain all the information that you may otherwise deem important. For more complete information, you should read the
entire deposit agreement and the form of ADR which contains the terms of your ADSs. You can read a copy of the deposit agreement which 
is filed as an exhibit to this Annual Report on Form 20-F.

Share Dividends and Other Distributions 

How  will  I  receive  dividends  and  other  distributions  on  the  ordinary  shares  underlying  my  ADSs?  We  may  make  various  types  of 
distributions  with  respect  to  our  securities.  The  depositary  has  agreed  that,  to  the  extent  practicable,  it  will  distribute  to  you  the  cash 
dividends  or  other  distributions  it  or  the  custodian  receives  on  ordinary  shares  or  other  deposited  securities,  after  converting  any  cash 
received  into  U.S.  dollars  (if  it  determines  such  conversion  may  be  made  on  a  reasonable  basis)  and,  in  all  cases,  making  any  necessary 
deductions provided for in the deposit agreement. The depositary may utilize a division, branch or affiliate of JPMorgan to direct, manage 
and/or execute any public and/or private sale of securities under the deposit agreement. Such division, branch and/or affiliate may charge the 
depositary a fee in connection with such sales, which fee is considered an expense of the depositary. You will receive these distributions in 
proportion to the number of underlying securities that your ADSs represent. 

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner: 

•

•

•

Cash. The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or other cash distribution or 
the  net  proceeds  of  sales  of  any  other  distribution  or  portion  thereof  (to  the  extent  applicable),  on  an  averaged  or  other 
practicable  basis,  subject  to  (i)  appropriate  adjustments  for  taxes  withheld,  (ii)  such  distribution  being  impermissible  or 
impracticable with respect to certain registered ADR holders, and (iii) deduction of the depositary’s and/or its agents’ fees and 
expenses in (1) converting any foreign currency to U.S. dollars to the extent that it determines that such conversion may be 
made  on  a  reasonable  basis,  (2)  transferring  foreign  currency  or  U.S.  dollars  to  the  United  States  by  such  means  as  the 
depositary may determine to the extent that it determines that such transfer may be made on a reasonable basis, (3) obtaining 
any  approval  or  license  of  any  governmental  authority  required  for  such  conversion  or  transfer,  which  is  obtainable  at  a 
reasonable  cost  and  within  a  reasonable  time  and  (4)  making  any  sale  by  public  or  private  means  in  any  commercially 
reasonable manner. If exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may 
lose some or all of the value of the distribution. 

Shares. In the case of a dividend or free distribution in ordinary shares, the depositary will issue additional ADRs to evidence 
the number of ADSs representing such ordinary shares. Only whole ADSs will be issued. Any ordinary shares which would 
result in fractional ADSs will be sold and the net proceeds will be distributed in the same manner as cash to the ADR holders 
entitled thereto. 

Rights to receive additional ordinary shares. In the case of a distribution of rights to subscribe for additional ordinary shares or 
other  rights,  if  we  timely  provide  evidence  satisfactory  to  the  depositary  that  it  may  lawfully  distribute  such  rights,  the 
depositary will distribute warrants or other instruments in the discretion of the depositary representing such rights. However, if 
we do not timely furnish such evidence, the depositary may: 

(i) Sell such rights if practicable and distribute the net proceeds in the same manner as cash to the ADR holders entitled 

thereto; or 

(ii)

(If it is not practicable to sell such rights by reason of the non-transferability of the rights, limited markets therefor, their 
short duration or otherwise, do nothing, in which case ADR holders will receive nothing and the rights may lapse. 

Other Distributions.  In  the  case  of  a  distribution  of  securities  or  property  other  than  those  described  above,  the  depositary  may  either  (i) 
distribute such securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution 
of such securities or property not to be equitable and practicable, sell such securities or property and distribute any net proceeds in the same 
way it distributes cash. 

If the depositary determines in its discretion that any distribution described above is not practicable with respect to any specific registered 
ADR holder, the depositary may choose any method of distribution that it deems practicable, including the distribution of foreign currency, 
securities or property, or it may retain such items, without liability for interest thereon or investment thereof, on behalf of the ADR holder as 
deposited securities, in which case the ADSs will also represent the retained items. 

 Any U.S. dollars will be distributed by checks drawn on a bank in the United States for whole dollars and cents. Fractional cents will be 
withheld without liability and dealt with by the depositary in accordance with its then current practices. 

131

The depositary is not responsible if it fails to determine that any distribution or action is lawful or reasonably practicable. 

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, 
shares  or  other  securities  at  a  specified  price,  nor  that  any  of  such  transactions  can  be  completed  within  a  specified  time  period.  All 
purchases and sales of securities will be handled by the depositary in accordance with its then current policies, which are currently set forth 
in  the  “Depositary  Receipt  Sale  and  Purchase  of  Security”  section  of  https://www.adr.com/Investors/FindOutAboutDRs,  the  location  and 
contents of which the depositary shall be solely responsible for. 

Deposit, Withdrawal and Cancellation 

How  does  the  depositary  issue  ADSs?  Subject  to  any  restrictions  on  deposit  provided  for  under  the  laws  of  the  Cayman  Islands  and  the 
deposit  agreement,  the  depositary  will  issue  ADSs  against  the  deposit  of:  (i)  ordinary  shares  in  registered  form,  validly  issued  and 
outstanding;  (ii)  rights  to  receive  ordinary  shares  from  us  or  any  registrar,  transfer  agent,  clearing  agent  or  other  entity  recording  share 
ownership or transactions, subject in each case to payment of the fees and expenses owing to the depositary in connection with such issuance. 

Ordinary shares deposited in the future with the custodian must be accompanied by certain documents, including Share certificates, and a 
certified share extract, reflecting the registration of the shares in the name of JPMorgan, as depositary for the benefit of holders of ADRs or 
in such other name as the depositary shall direct, a delivery order directing the depositary to issue ADSs to, or upon the written order of, the 
person designated in such order, instruments assigning to the custodian, the depositary or the nominee of either of them any distribution on 
the ordinary shares so deposited or indemnity therefor, and proxies entitling the custodian to vote the deposited ordinary shares. 

The custodian will hold all deposited ordinary shares for the account and to the order of the depositary for the benefit of holders of ADRs. 
ADR  holders  thus  have  no  direct  ownership  interest  in  the  ordinary  shares  and  only  have  such  rights  as  are  contained  in  the  deposit 
agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited ordinary 
shares. The deposited ordinary shares and any such additional items are referred to as “deposited securities.” 

Upon  each  deposit  of  ordinary  shares,  receipt  of  related  delivery  documentation  and  compliance  with  the  other  provisions  of  the  deposit 
agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will 
issue an ADR or ADRs in the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is 
entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositary’s direct registration system, and a 
registered holder will receive periodic statements from the depositary which will show the number of ADSs registered in such holder’s name. 
An  ADR  holder  can  request  that  the  ADSs  not  be  held  through  the  depositary’s  direct  registration  system  and  that  a  certificated  ADR  be 
issued. 

How  do  ADR  holders  cancel  an  ADS  and  obtain  deposited  securities?  In  accordance  with  the  deposit  agreement  and  subject  to  the 
requirements of the laws of the Cayman Islands, an ADR holder may request the depositary to withdraw from the depositary receipt facility 
created by the deposit agreement the ordinary shares represented by such holder’s ADRs and transfer such ordinary shares to such holder or, 
upon  the  written  order  of  any  person  designated  in  such  ADR  holder’s  written  order,  upon  surrender  of  (a)  a  certificated  ADR  in  a  form 
satisfactory  to  the  depositary  or  (b)  proper  instructions  and  documentation  in  the  case  of  an  ADR  issued  through  the  depositary’s  direct 
registration system, as the case may be, then an ADR holder hereof is entitled to delivery at, or to the extent in dematerialized form from, the 
custodian’s office of the deposited securities at the time represented by the ADSs evidenced by this ADR. At the request, risk and expense of 
the holder hereof, the depositary may deliver such deposited securities at such other place as may have been requested by the holder. 

132

The depositary may only restrict the withdrawal of deposited securities in connection with: 

•

•

•

Temporary  delays  caused  by  closing  our  transfer  books  or  those  of  the  depositary  or  the  deposit  of  ordinary  shares  in 
connection with voting at a shareholders’ meeting, or the payment of dividends; 

The payment of fees, taxes and similar charges; or 

Compliance with any U.S. or foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited 
securities. 

Record Dates 

The depositary may, after consultation with us if practicable, fix record dates (which, to the extent applicable, shall be as near as practicable 
to any corresponding record dates set by us) for the determination of the registered ADR holders who will be entitled (or obligated, as the 
case may be): 

•

•

•

•

To receive any distribution on or in respect of deposited securities, 

To give instructions for the exercise of voting rights, 

To pay the fee assessed by the depositary for administration of the ADR program and for any expenses as provided for in the 
deposit agreement, or 

To receive any notice or to act or be obligated in respect of other matters, 

All subject to the provisions of the deposit agreement. 

Voting Rights 

How do I vote? If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary 
how  to  exercise  the  voting  rights  for  the  shares  which  underlie  your  ADSs.  As  soon  as  practicable  after  receipt  from  us  of  notice  of  any 
meeting at which the holders of shares are entitled to vote, or of our solicitation of consents or proxies from holders of shares, the depositary 
shall fix the ADS record date in accordance with the provisions of the deposit agreement. The depositary shall, if we request in writing in a 
timely manner at least 30 days prior to the date of such vote or meeting and at our expense and provided no legal prohibitions exist, distribute 
to the registered ADR holders a notice stating final information particular to the voting materials received by the depositary and describing 
how you may instruct, or, subject to the next paragraph, will be deemed to instruct, the depositary to exercise the voting rights for the shares 
which underlie your ADSs, including instructions for giving a discretionary proxy to a person designated by us. Each ADR holder shall be 
solely responsible for the forwarding of voting notices to the beneficial owners of ADSs registered in such holder’s name. In accordance with
our memorandum and articles of association, a shareholder may not exercise its own vote or by proxy on behalf of another shareholder of the 
company in respect of any contract or proposed contract or arrangement if such shareholder may be interested therein. Accordingly, no ADR 
holder shall instruct the depositary to vote on its behalf on any matter to be considered at the relevant meeting in respect of which such holder 
is interested. 

 To the extent we have provided the depositary with at least 35 days’ notice of a proposed meeting, the notice will be received by all ADR 
holders and beneficial owners no less than 10 days prior to the date of the meeting and/or the cut-off date for the solicitation of consents, and 
the  depositary  does  not  receive  instructions  on  a  particular  agenda  item  from  a  ADR  holder  (including,  without  limitation,  any  entity  or 
entities acting on behalf of the nominee for The Depository Trust Company) in a timely manner, such holder shall be deemed, and in the 
deposit agreement the depositary is instructed to deem such holder, to have instructed the depositary to give a discretionary proxy for such 
agenda item(s) to a person designated by us to vote the shares represented by their ADSs for which actual instructions were not so given by 
all such ADR holders on such agenda item(s), provided that no such instruction shall be deemed given and no discretionary proxy shall be 
given unless (1) we inform the depositary in writing that (a) we wish such proxy to be given with respect to such agenda item(s), (b) there is 
no  substantial  opposition  existing  with  respect  to  such  agenda  item(s)  and  (c)  such  agenda  item(s),  if  approved,  would  not  materially  or 
adversely affect the rights of holders of shares and (2) we have provided the depositary with an opinion of our counsel, in form and substance 
satisfactory to the depositary, confirming that (a) the granting of such discretionary proxy does not subject the depositary to any reporting 
obligations in the Cayman Islands, (b) the granting of such proxy will not result in a violation of Cayman Island laws, rules, regulations or 
permits, (c) the voting arrangement and deemed instruction as contemplated herein will be given effect under Cayman Islands laws, rules and 
regulations, and (d) the granting of such discretionary proxy will not under any circumstances result in the ADSs being treated as assets of 
the depositary under Cayman Island laws, rules or regulations. 

133

Holders are strongly encouraged to forward their voting instructions to the depositary as soon as possible. For instructions to be valid, the 
ADR  department  of  the  depositary  that  is  responsible  for  proxies  and  voting  must  receive  them  in  the  manner  and  on  or  before  the  time 
specified, notwithstanding that such instructions may have been physically received by the depositary prior to such time. The depositary will 
not itself exercise any voting discretion. Furthermore, neither the depositary nor its agents are responsible for any failure to carry out any 
voting instructions, for the manner in which any vote is cast or for the effect of any vote. Notwithstanding anything contained in the deposit 
agreement or any ADR, the depositary may, to the extent not prohibited by law or regulations, or by the requirements of the stock exchange 
on  which  the  ADSs  are  listed,  in  lieu  of  distribution  of  the  materials  provided  to  the  depositary  in  connection  with  any  meeting  of,  or 
solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders of ADRs a notice that provides 
such  holders  with,  or  otherwise  publicizes  to  such  holders,  instructions  on  how  to  retrieve  such  materials  or  receive  such  materials  upon 
request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials). 

There is no guarantee that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons 
who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. 

We have advised the depositary that under the Cayman Islands law and our memorandum and articles of association, voting at any meeting of 
our shareholders is by show of hands unless a poll is (before or on the declaration of the results of the show of hands) demanded. In the event 
that  voting  on  any  resolution  or  matter  is  conducted  on  a  show  of  hands  basis  in  accordance  with  the  memorandum  and  articles  of 
association,  the  depositary  will  refrain  from  voting  and  the  voting  instructions  received  by  the  depositary  from  holders  shall  lapse.  The 
depositary will not demand a poll or join in demanding a poll, whether or not requested to do so by holders of ADSs. 

Reports and Other Communications 

Will  ADR  holders  be  able  to  view  our  reports?  The  depositary  will  make  available  for  inspection  by  ADR  holders  at  the  offices  of  the 
depositary and the custodian, or upon request made to the depositary (which request may be refused by the depositary at its discretion), the
deposit agreement, the provisions of or governing deposited securities, and any written communications from us which are both received by 
the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities. 

 Additionally, if we make any written communications generally available to holders of our ordinary shares, and we furnish copies thereof (or 
English translations or summaries) to the depositary, it will distribute the same to registered ADR holders. 

Fees and Expenses 

What fees and expenses will I be responsible for paying?  The  depositary  may  charge  each  person  to  whom  ADSs  are  issued,  including, 
without  limitation,  issuances  against  deposits  of  ordinary  shares,  issuances  in  respect  of  share  distributions,  rights  and  other  distributions, 
issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other 
transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or 
whose ADRs are cancelled or reduced for any other reason, $5.00 for each 100 ADSs (or any portion thereof) issued, delivered, reduced, 
cancelled or surrendered, as the case may be. The depositary may sell (by public or private sale) sufficient securities and property received in 
respect of a share distribution, rights and/or other distributions prior to such deposit to pay such charge. 

The  following  additional  charges  shall  be  incurred  by  the  ADR  holders,  by  any  party  depositing  or  withdrawing  shares  or  by  any  party 
surrendering  ADSs  and/or  to  whom  ADSs  are  issued  (including,  without  limitation,  issuances  pursuant  to  a  stock  dividend  or  stock  split 
declared by us or an exchange of stock regarding the ADSs or the deposited securities or a distribution of ADSs), whichever is applicable: 

•

•

•

A fee of up to $0.05 per ADS upon which any cash distribution made pursuant to the deposit agreement; 

An aggregate fee of $0.05 or less per ADS per calendar year (or portion thereof) for services performed by the depositary in 
administering the ADRs (which fee may be charged on a periodic basis during each calendar year and shall be assessed against 
holders of ADRs as of the record date or record dates set by the depositary during each calendar year and shall be payable in 
the manner described in the next succeeding provision); 

A  fee  for  the  reimbursement  of  such  fees,  charges  and  expenses  as  are  incurred  by  the  depositary  and/or  any  of  its  agents 
(including, without limitation, the custodian and expenses incurred on behalf of ADR holders 

134

in  connection  with  compliance  with  foreign  exchange  control  regulations  or  any  law  or  regulation  relating  to  foreign 
investment)  in  connection  with  the  servicing  of  the  ordinary  shares  or  other  deposited  securities,  the  sale  of  securities 
(including,  without  limitation,  deposited  securities),  the  delivery  of  deposited  securities  or  otherwise  in  connection  with  the 
depositary’s or its custodian’s compliance with applicable law, rule or regulation (which fees and charges shall be assessed on a 
proportionate basis against ADR holders as of the record date or dates set by the depositary and shall be payable at the sole 
discretion of the depositary by billing such ADR holders or by deducting such charge from one or more cash dividends or other 
cash distributions); 

A fee for the distribution of securities (or the sale of securities in connection with a distribution), such fee being in an amount 
equal to the $0.05 per ADS issuance fee for the execution and delivery of ADSs which would have been charged as a result of 
the deposit of such securities (treating all such securities as if they were ordinary shares) but which securities or the net cash 
proceeds from the sale thereof are instead distributed by the depositary to those ADR holders entitled thereto; 

Stock transfer or other taxes and other governmental charges; 

SWIFT, cable, telex and facsimile transmission and delivery charges incurred at your request in connection with the deposit or 
delivery of shares, ADRs or deposited securities; 

Transfer or registration fees for the registration or transfer of deposited securities on any applicable register in connection with 
the deposit or withdrawal of deposited securities; 

Fees of any division, branch or affiliate of JPMorgan utilized to direct, manage and/or execute any public and/or private sale of 
securities under the deposit agreement.

Foreign  Exchange  Related  Matters.  To  facilitate  the  administration  of  various  depositary  receipt  transactions,  including  disbursement  of 
dividends  or  other  cash  distributions  and  other  corporate  actions,  the  depositary  may  engage  the  foreign  exchange  desk  within  JPMorgan 
and/or its affiliates in order to enter into spot foreign exchange transactions to convert foreign currency into U.S. dollars (FX Transactions). 
For certain currencies, FX Transactions are entered into with JPMorgan or an affiliate, as the case may be, acting in a principal capacity. For 
other currencies, FX Transactions are routed directly to and managed by an unaffiliated local custodian (or other third party local liquidity 
provider), and neither the JPMorgan nor any of its affiliates is a party to such FX Transactions. 

The foreign exchange rate applied to an FX Transaction will be either (a) a published benchmark rate, or (b) a rate determined by a third 
party local liquidity provider, in each case plus or minus a spread, as applicable. The depositary will disclose which foreign exchange rate 
and spread, if any, apply to such currency on the “Disclosure” page (or successor page) of www.adr.com. Such applicable foreign exchange 
rate and spread may (and neither the depositary, JPMorgan nor any of their affiliates is under any obligation to ensure that such rate does not) 
differ from rates and spreads at which comparable transactions are entered into with other customers or the range of foreign exchange rates 
and spreads at which JPMorgan or any of its affiliates enters into foreign exchange transactions in the relevant currency pair on the date of 
the  FX  Transaction.  Additionally,  the  timing  of  execution  of  an  FX  Transaction  varies  according  to  local  market  dynamics,  which  may 
include regulatory requirements, market hours and liquidity in the foreign exchange market or other factors. Furthermore, JPMorgan and its 
affiliates may manage the associated risks of their position in the market in a manner they deem appropriate without regard to the impact of 
such activities on us, the depositary, holders or beneficial owners. The spread applied does not reflect any gains or losses that may be earned 
or incurred by JPMorgan and its affiliates as a result of risk management or other hedging related activity. 

Notwithstanding the foregoing, to the extent we provide U.S. dollars to the depositary, neither JPMorgan nor any of its affiliates will execute 
an FX Transaction as set forth herein. In such case, the depositary will distribute the U.S. dollars received from us. 

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements 
from time to time between us and the depositary. The charges described above may be amended from time to time by agreement between us 
and  the  depositary.  The  right  of  the  depositary  to  receive  payment  of  fees,  charges  and  expenses  as  provided  above  shall  survive  the 
termination of the deposit agreement. 

135

The depositary anticipates reimbursing us for certain expenses incurred by us that are related to the establishment and maintenance of the 
ADR program upon such terms and conditions as we and the depositary may agree from time to time. The depositary may make available to 
us a set amount or a portion of the depositary fees charged in respect of the ADR program or otherwise upon such terms and conditions as we 
and the depositary may agree from time to time. The depositary collects its fees for issuance and cancellation of ADSs directly from investors 
depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for 
making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay 
the  fees.  The  depositary  may  collect  its  annual  fee  for  depositary  services  by  deduction  from  cash  distributions,  or  by  directly  billing 
investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts 
owing  from  distributions  made  to  holders  of  ADSs.  If,  however,  no  distribution  exists  and  payment  owing  is  not  timely  received  by  the 
depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and expenses owing until such 
fees  and  expenses  have  been  paid.  At  the  discretion  of  the  depositary,  all  fees  and  charges  owing  under  the  deposit  agreement  are  due  in 
advance and/or when declared owing by the depositary. 

Payment of Taxes 

If any taxes or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the custodian or 
the  depositary  with  respect  to  any  ADR,  any  deposited  securities  represented  by  the  ADSs  evidenced  thereby  or  any  distribution  thereon, 
such tax or other governmental charge shall be paid by the ADR holders to the depositary and by holding or having held an ADR or any 
ADSs evidenced thereby, the holder and all beneficial owners thereof and all prior holders and beneficial owners holders thereof, jointly and 
severally, agree to indemnify, defend and save harmless each of the depositary and its agents in respect of such tax or other governmental 
charge.  Each  Holder  of  this  ADR  and  beneficial  owner  of  the  ADSs  evidenced  thereby,  and  each  prior  holder  and  beneficial  owner  and 
thereof  (collectively,  the  Tax  Indemnitors),  by  holding  or  having  held  an  ADR  or  an  interest  in  ADSs,  acknowledges  and  agrees  that  the 
depositary  shall  have  the  right  to  seek  payment  of  amounts  owing  with  respect  to  this  ADR  from  any  one  or  more  Tax  Indemnitor(s)  as 
determined  by  the  depositary  in  its  sole  discretion,  without  any  obligation  to  seek  payment  from  any  other  Tax  Indemnitor(s).  If  an  ADR 
holder  owes  any  tax  or  other  governmental  charge,  the  depositary  may  (i)  deduct  the  amount  thereof  from  any  distributions,  or  (ii)  sell 
deposited  securities  (by  public  or  private  sale)  and  deduct  the  amount  owing  from  the  net  proceeds  of  such  sale.  In  either  case  the  ADR 
holder remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, 
registration  of  transfer,  split-up  or  combination  of  ADRs  or  withdrawal  of  deposited  securities  until  such  payment  is  made.  If  any  tax  or 
governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from 
any cash distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) in such 
amounts  and  in  such  manner  as  the  depositary  deems  necessary  and  practicable  to  pay  such  taxes  and  shall  distribute  any  remaining  net 
proceeds or the balance of any such property after deduction of such taxes to the ADR holders entitled thereto. 

Notwithstanding  the  above,  we  will  pay  all  stamp  duties  and  other  similar  duties  or  taxes  payable  in  the  Cayman  Islands,  Singapore,  the 
United States of America and any other jurisdiction, on or in connection with the constitution and issue of the ADSs and the execution or 
other event concerning the deposit agreement. If any legal proceedings are taken to enforce our obligations under the deposit agreement or 
the ADSs and for the purpose of such proceedings any of them are required to be taken into or enforced in any jurisdiction and stamp duties 
or  other  similar  duties  or  taxes  become  payable  in  connection  with  such  proceedings  in  such  jurisdiction,  the  ADR  holders  will  pay  (or 
reimburse  the  person  making  a  valid  payment  of)  all  such  stamp  duties  and  other  similar  duties  and  taxes,  including  any  penalties  and 
interest, unless otherwise ordered by a court of competent jurisdiction in such proceedings. The depositary may sell any deposited securities 
and cancel ADSs with respect thereof in order to pay any such stamp duties or other similar duties or taxes owed under the deposit agreement 
by ADR holders without the depositary being required to request payment thereof from the ADR holders. 

136

Each holder and beneficial owner agrees to indemnify us, the depositary, its custodian and any of our or their respective officers, directors, 
employees,  agents  and  affiliates  against,  and  hold  each  of  them  harmless  from,  any  claims  by  any  governmental  authority  with  respect  to 
taxes,  additions  to  tax,  penalties  or  interest  arising  out  of  any  refund  of  taxes,  reduced  rate  of  withholding  at  source  or  other  tax  benefit 
obtained,  and  such  obligations  of  the  holders  and  beneficial  owners  shall  survive  the  transfer  of  ADSs,  any  surrender  of  ADSs  and 
withdrawal of deposited securities and any termination of the deposit agreement. 

Reclassifications, Recapitalizations and Mergers 

If we take certain actions that affect the deposited securities, including (i) any change in par value, split-up, consolidation, cancellation or 
other reclassification of deposited securities or (ii) any distributions of ordinary shares or other property not made to holders of ADRs or (iii) 
any  recapitalization,  reorganization,  merger,  consolidation,  liquidation,  receivership,  bankruptcy  or  sale  of  all  or  substantially  all  of  our 
assets, then the depositary may choose to, and shall if reasonably requested by us: 

(1) Amend the form of ADR; 

(2) Distribute additional or amended ADRs; 

(3) Distribute cash, securities or other property it has received in connection with such actions; 

(4) Sell by public or private sale any securities or property received; or 

(5) None of the above. 

If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the 
deposited securities and each ADS will then represent a proportionate interest in such property. 

Amendment and Termination 

How may the deposit agreement be amended? 

We  may  agree  with  the  depositary  to  amend  the  deposit  agreement  and  the  ADSs  without  your  consent  for  any  reason.  ADR  holders  or 
beneficial owners must be given at least 30 days’ notice of any amendment that imposes or increases any fees or charges (other than stock 
transfer  or  other  taxes  and  other  governmental  charges,  transfer  or  registration  fees,  SWIFT,  cable,  telex  or  facsimile  transmission  costs, 
delivery costs or other such expenses), or that otherwise prejudices any substantial existing right of ADR holders or beneficial owners. Such 
notice need not describe in detail the specific amendments effectuated thereby, but must identify to ADR holders a means to access the text of 
such amendment. If an ADR holder continues to hold an ADR or ADRs after being so notified, such ADR holder is deemed to agree to such 
amendment and to be bound by the deposit agreement as so amended. Any amendments or supplements which (i) are reasonably necessary 
(as agreed by us and the depositary) in order for (a) the ADSs to be registered on Form F-6 under the Securities Act of 1933 or (b) the ADSs 
or shares to be traded solely in electronic book-entry form and (ii) do not in either such case impose or increase any fees or charges to be 
borne by ADR holders, shall be deemed not to prejudice any substantial rights of ADR holders or beneficial owners. Notwithstanding the 
foregoing,  if  any  governmental  body  or  regulatory  body  should  adopt  new  laws,  rules  or  regulations  which  would  require  amendment  or 
supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement 
the deposit agreement and the ADR at any time in accordance with such changed laws, rules or regulations. Such amendment or supplement 
may take effect before a notice is given or within any other period of time as required for compliance. No amendment, however, will impair 
your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable 
law. 

How may the deposit agreement be terminated? 

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination 
the  registered  holders  of  ADRs  at  least  30  days  prior  to  the  date  fixed  in  such  notice  for  such  termination;  provided,  however,  if  the 
depositary  shall  have  (i)  resigned  as  depositary  under  the  deposit  agreement,  notice  of  such  termination  by  the  depositary  shall  not  be 
provided to registered holders unless a successor depositary shall not be operating under the deposit agreement within 60 days of the date of 
such resignation, and (ii) been removed as depositary under the deposit agreement, notice of such termination by the depositary shall not be 
provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the 60th day after 
our notice of removal was first provided to the depositary. Notwithstanding anything to the contrary in the 

137

deposit agreement without notice to us, the depositary may terminate the deposit agreement without notice to us, but subject to giving 30 
days’ notice to the ADR holders, if: (i) we become bankrupt or insolvent, (ii) we effect (or will effect) a redemption of all or substantially all 
of  the  deposited  securities,  or  a  cash  or  share  distribution  representing  a  return  of  all  or  substantially  all  of  the  value  of  the  deposited 
securities, or (iii) there occurs a merger, consolidation, sale of assets or other transaction as a result of which securities or other property are 
delivered in exchange for or in lieu of deposited securities. 

After termination, the depositary shall use its reasonable efforts to ensure that the ADSs cease to be DTC eligible so that neither DTC nor any 
of its nominees shall thereafter be a holder. At such time as the ADSs cease to be DTC eligible and/or neither DTC nor any of its nominees is 
a holder, the depositary shall (a) instruct its custodian to deliver all deposited securities to us along with a general stock power that refers to 
the names set forth on the ADR Register and (b) provide us with a copy of the ADR Register. Upon receipt of such deposited securities and 
the ADR Register, we shall use our best efforts to issue to each holder a share certificate representing the shares represented by the ADSs 
reflected on the ADR Register in such holder’s name and to deliver such share certificate to the holder at the address set forth on the ADR 
Register. After providing such instruction to the custodian and delivering a copy of the ADR Register to us, the depositary and its agents shall 
have no further obligations. 

Limitations on Obligations and Liability to ADR holders 

Limits on our obligations and the obligations of the depositary; limits on liability to ADR holders and holders of ADSs.   Prior to the issue, 
registration, registration of transfer, split-up, combination, or withdrawal of any ADRs, or the delivery of any distribution in respect thereof, 
and from time to time in the case of the production of proofs as described below, we or the depositary or its custodian may require: 

•

•

•

Payment  with  respect  thereto  of  (i)  any  stock  transfer  or  other  tax  or  other  governmental  charge,  (ii)  any  stock  transfer  or 
registration fees in effect for the registration of transfers of ordinary shares or other deposited securities upon any applicable 
register and (iii) any applicable fees and expenses described in the deposit agreement; 

The  production  of  proof  satisfactory  to  it  of  (i)  the  identity  of  any  signatory  and  genuineness  of  any  signature  and  (ii)  such 
other information, including without limitation, information as to citizenship, residence, exchange control approval, beneficial 
ownership of any securities, compliance with applicable law, regulations, provisions of or governing deposited securities and 
terms of the deposit agreement and the ADRs, as it may deem necessary or proper; and 

Compliance with such regulations as the depositary may establish consistent with the deposit agreement. 

The  issuance  of  ADRs,  the  acceptance  of  deposits  of  ordinary  shares,  the  registration,  registration  of  transfer,  split-up  or  combination  of 
ADRs  or  the  withdrawal  of  shares,  may  be  suspended,  generally  or  in  particular  instances,  when  the  ADR  register  or  any  register  for 
deposited securities is closed or when any such action is deemed advisable by the depositary; provided that the ability to withdraw shares 
may  only  be  limited  under  the  following  circumstances:  (i)  temporary  delays  caused  by  closing  transfer  books  of  the  depositary  or  our 
transfer books or the deposit of ordinary shares in connection with voting at a shareholders’ meeting, or the payment of dividends, (ii) the 
payment  of  fees,  taxes,  and  similar  charges,  and  (iii)  compliance  with  any  laws  or  governmental  regulations  relating  to  ADRs  or  to  the 
withdrawal of deposited securities. 

138

The  deposit  agreement  expressly  limits  the  obligations  and  liability  of  the  depositary,  ourselves  and  our  respective  directors,  officers, 
employees, agents and affiliates, provided, however, that no disclaimer of liability under the Securities Act of 1933 is intended by any of the 
limitations of liabilities provisions of the deposit agreement. In the deposit agreement it provides that neither we nor the depositary nor any 
such other party will be liable to holders or beneficial owners if: 

•

•

•

•

Any present or future law, rule, regulation, fiat, order or decree of the United States, the Cayman Islands, Singapore or any 
other  country  or  jurisdiction,  or  of  any  governmental  or  regulatory  authority  or  securities  exchange  or  market  or  automated 
quotation system, the provisions of or governing any deposited securities, any present or future provision of our charter, any act 
of  God,  war,  terrorism,  nationalization,  expropriation,  currency  restrictions,  work  stoppage,  strike,  civil  unrest,  revolutions, 
rebellions,  explosions,  computer  failure  or  circumstance  beyond  our,  the  depositary’s  or  any  such  other  party’s  direct  and 
immediate control shall prevent or delay, or shall cause any of them to be subject to any civil or criminal penalty in connection 
with, any act which the deposit agreement or the ADRs provide shall be done or performed by us, the depositary or such other 
party (including, without limitation, voting); 

By reason of any non-performance or delay, caused in the performance of any act or things which by the terms of the deposit 
agreement  it  is  provided  shall  or  may  be  done  or  performed  or  it  exercises  or  fails  to  exercise  discretion  under  the  deposit 
agreement or the ADRs including, without limitation, any failure to determine that any distribution or action may be lawful or 
reasonably practicable; 

It  performs  its  obligations  under  the  deposit  agreement  and  ADRs  without  gross  negligence  or  willful  misconduct  and  the 
depositary shall not be a fiduciary or have any fiduciary duty to holders or beneficial owners; or 

It  takes  any  action  or  refrains  from  taking  any  action  in  reliance  upon  the  advice  of  or  information  from  legal  counsel, 
accountants, any person presenting ordinary shares for deposit, any registered holder of ADRs, or any other person believed by 
it to be competent to give such advice or information, or in the case of the depositary only, from us. 

We  and  the  depositary  and  its  agents  may  rely  and  shall  be  protected  in  acting  upon  any  written  notice,  request,  direction,  instruction  or 
document believed by it to be genuine and to have been signed, presented or given by the proper party or parties. 

Neither we, the depositary nor our respective agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding 
in respect of any deposited securities or the ADRs which in its opinion may involve it in expense or liability, if indemnity satisfactory to it 
against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary and its 
agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit 
agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such 
information  is  requested  or  required  by  or  pursuant  to  any  lawful  authority,  including  without  limitation  laws,  rules,  regulations, 
administrative or judicial process, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions made by, 
or the insolvency of, any securities depository, clearing agency or settlement system. Furthermore, the depositary shall not be responsible for, 
and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan. 
Notwithstanding anything to the contrary contained in the deposit agreement or any ADRs, the depositary shall not be responsible for, and 
shall incur no liability in connection with or arising from, any act or omission to act on the part of the custodian except to the extent that any 
holder has incurred liability directly as a result of the custodian having (i) committed fraud or willful misconduct in the provision of custodial 
services  to  the  depositary  or  (ii)  failed  to  use  reasonable  care  in  the  provision  of  custodial  services  to  the  depositary  as  determined  in 
accordance with the standards prevailing in the jurisdiction in which the custodian is located. The depositary shall not have any liability for 
the  price  received  in  connection  with  any  sale  of  securities,  the  timing  thereof  or  any  delay  in  action  or  omission  to  act  nor  shall  it  be 
responsible for any error or delay in action, omission to act, default or negligence on the part of the party so retained in connection with any 
such sale or proposed sale. 

The depositary has no obligation to inform ADR holders or other holders of an interest in any ADSs about the requirements of the laws, rules 
or  regulations  of  any  country  or  jurisdiction  or  of  any  governmental  or  regulatory  authority  or  any  securities  exchange  or  market  or 
automated quotation system, or any changes therein or thereto. 

139

Additionally, none of us, the depositary or the custodian shall be liable for the failure by any registered holder or beneficial owner of ADRs 
to obtain the benefits of credits or refunds of non-U.S. tax paid against such holder’s or beneficial owner’s income tax liability. Neither we 
nor the depositary shall incur any liability for any tax or tax consequences that may be incurred by registered holders or beneficial owners on 
account of their ownership of ADRs or ADSs. 

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for 
the manner in which any such vote is cast or for the effect of any such vote. The depositary may rely upon instructions from us or our counsel 
in respect of any approval or license required for any currency conversion, transfer or distribution. The depositary shall not incur any liability 
for  the  content  of  any  information  submitted  to  it  by  us  or  on  our  behalf  for  distribution  to  ADR  holders  or  for  any  inaccuracy  of  any 
translation thereof, for any investment risk associated with acquiring an interest in the deposited securities, for the validity or worth of the 
deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or 
for the failure or timeliness of any notice from us. The depositary shall not be liable for any acts or omissions made by a successor depositary 
whether in connection with a previous act or omission of the depositary or in connection with any matter arising wholly after the removal or 
resignation of the depositary. 

Neither we, the depositary nor any of our respective directors, officers, employees, agents or affiliates, nor our company’s supervisors, shall 
be liable to registered holders or beneficial owners for any indirect, special, punitive or consequential damages (including, without limitation, 
legal fees and expenses) or lost profits, in each case of any form incurred by any person or entity (including, without limitation, holders and 
beneficial owners), whether or not foreseeable and regardless of the type of action in which such a claim may be brought. 

In the deposit agreement each party thereto (including, for avoidance of doubt, each holder and beneficial owner and/or holder of interests in 
ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or 
proceeding against the depositary and/or us directly or indirectly arising out of or relating to the ordinary shares or other deposited securities, 
the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, 
common law or any other theory). 

The depositary and its agents may own and deal in any class of securities of our company and our affiliates and in ADRs. 

Disclosure of Interest in ADSs 

To the extent that the provisions of or governing any deposited securities may require disclosure of or impose limits on beneficial or other 
ownership of, or interests in, deposited securities, other ordinary shares and other securities and may provide for blocking transfer, voting or 
other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and ownership limitations and to 
comply with any reasonable instructions we may provide in respect thereof. 

Each ADR holder agrees to comply with requests from us pursuant to the laws, rules and regulations of the Cayman Islands, and Singapore, 
as  well  as  the  rules  and  regulations  of  any  stock  exchange  on  which  the  ordinary  shares  may  hereinafter  be  registered,  traded  or  listed  to 
provide  information,  inter  alia,  as  to  the  capacity  in  which  such  ADR  holder  owns  ADRs  (and  ordinary  shares  as  the  case  may  be)  and 
regarding the identity of any other person interested in such ADRs and the nature of such interest. 

140

Books of Depositary 

The  depositary  or  its  agent  will  maintain  a  register  for  the  registration,  registration  of  transfer,  combination  and  split-up  of  ADRs,  which 
register shall include the depositary’s direct registration system. Registered holders of ADRs may inspect such register at the depositary’s 
office at all reasonable times, but for the purpose of communicating with other ADR holders in the interest of the business of our company or 
a  matter  relating  to  the  deposit  agreement.  Such  register  may  be  closed  at  any  time  or  from  time  to  time,  when  deemed  expedient  by  the 
depositary. 

The depositary will maintain facilities for the delivery and receipt of ADRs. 

Appointment 

In the deposit agreement, each registered holder of ADRs and each beneficial owner, upon acceptance of any ADSs or ADRs (or any interest 
in any of them) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to: 

•

•

•

Be a party to and bound by the terms of the deposit agreement and the applicable ADR or ADRs, 

Appoint  the  depositary  its  attorney-in-fact,  with  full  power  to  delegate,  to  act  on  its  behalf  and  to  take  any  and  all  actions 
contemplated in the deposit agreement and the applicable ADR or ADRs, to adopt any and all procedures necessary to comply 
with applicable laws and to take such action as the depositary in its sole discretion may deem necessary or appropriate to carry 
out the purposes of the deposit agreement and the applicable ADR or ADRs, the taking of such actions to be the conclusive 
determinant of the necessity and appropriateness thereof, and 

Acknowledge and agree that (i) nothing in the deposit agreement or any ADR shall give rise to a partnership or joint venture 
among the parties thereto nor establish a fiduciary or similar relationship among such parties, (ii) the depositary, its divisions, 
branches and affiliates, and their respective agents, may from time to time be in the possession of non-public information about 
us, holders, beneficial owners and/or their respective affiliates, (iii) the depositary and its divisions, branches and affiliates may 
at any time have multiple banking relationships with us, holders, beneficial owners and/or the affiliates of any of them, (iv) the 
depositary and its divisions, branches and affiliates may, from time to time, be engaged in transactions in which parties adverse 
to us or the holders or beneficial owners may have interests, (v) nothing contained in the deposit agreement or any ADR(s) 
shall  (A)  preclude  the  depositary  or  any  of  its  divisions,  branches  or  affiliates  from  engaging  in  such  transactions  or 
establishing or maintaining such relationships, or (B) obligate the depositary or any of its divisions, branches or affiliates to 
disclose  such  transactions  or  relationships  or  to  account  for  any  profit  made  or  payment  received  in  such  transactions  or 
relationships, (vi) the depositary shall not be deemed to have knowledge of any information held by any branch, division or 
affiliate of the depositary and (vii) notice to a holder shall be deemed, for all purposes of the deposit agreement, to constitute 
notice to any and all beneficial owners of the ADSs evidenced by such holder’s ADRs. 

141

Governing Law, Submission to Jurisdiction and Arbitration 

The  deposit  agreement,  the  ADSs  and  the  ADRs  are  governed  by  and  construed  in  accordance  with  the  laws  of  the  State  of  New  York 
without  giving  effect  to  the  application  of  the  conflict  of  law  principles  thereof.  In  the  deposit  agreement,  we  have  submitted  to  the 
jurisdiction  of  the  state  and  federal  courts  of  the  State  of  New  York  and  appointed  an  agent  for  service  of  process  on  our  behalf. 
Notwithstanding the foregoing, subject to the terms described below, including the federal securities law carve-out set forth at the end of this 
sentence,  (i)  the  depositary  may  refer  any  such  suit,  action  or  proceedings  to  arbitration  in  accordance  with  the  provisions  of  the  deposit 
agreement, and, upon such referral, any such suit, action or proceeding instituted by us shall be finally decided in such arbitration rather than 
in  such  court,  (ii)  the  depositary  may,  in  its  sole  discretion,  elect  to  institute  any  dispute,  suit,  action,  controversy,  claim  or  proceeding 
directly  or  indirectly  based  on,  arising  out  of  or  relating  to  the  deposit  agreement  or  the  ADRs  or  the  transactions  contemplated  thereby, 
including  without  limitation  any  question  regarding  its  or  their  existence,  validity,  interpretation,  performance  or  termination,  against  any 
other  party  or  parties  to  the  deposit  agreement  (including,  without  limitation,  against  ADR  holders  and  beneficial  owners),  by  having  the
matter referred to and finally resolved by an arbitration conducted under the terms described below, and (iii) the depositary may in its sole 
discretion require that any dispute, suit, action, controversy, claim, or proceeding of the type described in clause (ii) above, brought against 
the depositary by any party or parties to the deposit agreement (including, without limitation, by ADR holders and beneficial owners ), shall 
be referred to and finally settled by an arbitration conducted under the terms described below; provided however, that to the extent there are 
specific  federal  securities  law  violation  aspects  to  any  disputes  against  us  and/or  the  depositary  brought  by  any  ADR  holder  or  beneficial 
owner, the federal securities law violation aspects of such disputes brought by an ADR holder and/or beneficial owner against us and/or the 
depositary may, at the option of such holder, remain in state or federal court in New York, New York and all other aspects, claims, disputes, 
legal  suits,  actions  and/or  proceedings  brought  by  such  holder  against  us  and/or  the  depositary,  including  those  brought  along  with,  or  in 
addition  to,  federal  securities  law  violation  claims,  would  be  referred  to  arbitration  in  accordance  with  the  provisions  of  the  deposit 
agreement. Any such arbitration shall be conducted either in New York, New York in accordance with the Commercial Arbitration Rules of 
the American Arbitration Association or in Hong Kong following the arbitration rules of the United Nations Commission on International 
Trade Law with the Hong Kong International Arbitration Centre serving as the appointing authority, and the language of any such arbitration 
shall be English. 

Notwithstanding  the  foregoing,  any  suit,  action  or  proceeding  based  on  the  deposit  agreement,  the  ADSs  or  the  ADRs  or  the  transactions 
contemplated thereby may be instituted by the depositary in any competent court in the Cayman Islands, Singapore and/or the United States. 

By  holding  an  ADS  or  an  interest  therein,  registered  holders  of  ADRs  and  beneficial  owners  each  irrevocably  agree  that  subject  to  the 
depositary’s rights, (i) any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit 
agreement, the ADSs or the ADRs or the transactions contemplated herein, therein or hereby may only be instituted in a state or federal court 
in New York, New York, and each irrevocably waives any objection which it may have to the laying of venue of any such proceeding, and 
irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

Not applicable.

Item 15. Controls and Procedures 

A.

Disclosure Controls and Procedures. 

Our management, with the participation of our Chief Executive Officer and Chief Operating Officer, has evaluated the effectiveness of our 
disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of December 31, 2022. Based on such 
evaluation, our Chief Executive Officer and Chief Operating Officer have concluded that, as of December 31, 2022, our disclosure controls 
and  procedures  were  effective  to  ensure  that  information  required  to  be  disclosed  by  us  in  the  reports  that  we  file  or  submit  under  the 
Exchange  Act  is  recorded,  processed,  summarized  and  reported,  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms,  and  is 
accumulated and communicated to our management, including our Chief Executive Officer and Chief Operating Officer, as appropriate to 
allow timely decisions regarding required disclosure.

B. Management’s Annual Report on Internal Control over Financial Reporting. 

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting (as defined in Rules 13a-
15(f)  and  15d-15(f)  under  the  Exchange  Act)  and  for  the  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate.

Our  management  has  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  framework  set  forth  by  the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 framework). 
Based on our evaluation, management has concluded that our internal control over financial reporting was effective as of December 31, 2022.

Attestation Report of the Registered Public Accounting Firm. 

This  annual  report  does  not  include  an  attestation  report  of  the  company’s  registered  public  accounting  firm  due  to  a  transition  period 
established by rules of the Securities and Exchange Commission for newly public companies.

D.

Changes in Internal Control over Financial Reporting. 

There  were  no  changes  in  our  internal  control  over  financial  reporting  (as  defined  in  Rule  13a-15(f)  of  the  Exchange  Act)  that  occurred 
during the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect, our internal control 
over financial reporting.

Item 16. [Reserved]

Item 16A. Audit Committee Financial Expert. 

Our Audit Committee is comprised of three of our non-executive directors, Mr. Howden, Mr. Hoffman and Dr. Graham. The audit committee 
consists exclusively of “independent directors” as such term is defined in Rule 10A-3 under the Exchange Act and under the listing standards 
of the Nasdaq Stock Market. Mr. Sun serves as chair of this committee. Our Board has determined that Mr. Hoffman is an “audit committee 
financial expert” as defined in Item 16A of Form 20-F. 

Item 16B. Code of Ethics. 

We have adopted a Code of Business Conduct that covers a broad range of matters including the handling of conflicts of interest, compliance 
issues and other corporate policies. Our Code of Business Conduct is applicable to all of our employees, officers and directors, including our 
principal executive officer, principal financial officer, principal accounting officer or controller, and persons performing similar functions. We 
have  posted  a  copy  of  our  Code  of  Business  Conduct  on  our  website  at  http://ir.aslanpharma.com/corporate-governance/highlights.  We 
undertake to provide a copy of this code without charge upon request. Please direct all requests to contact@aslanpharma.com. We expect that 
any  amendment  to  this  code,  or  any  waivers  of  its  requirements,  will  be  disclosed  on  our  website  and  approve  by  board  of  directors. 
Information contained on, or that can be accessed through, our website is not incorporated by reference into this annual report. See “Item 6.C. 
Directors, Senior Management and Employees— Code of Business Conduct and Ethics” for more information.

Item 16F. Change in Registrant’s Certifying Accountant.

Item 16G. Corporate Governance.

We  are  a  “foreign  private  issuer,”  as  defined  by  the  SEC.  As  a  result,  in  accordance  with  the  rules  and  regulations  of  The  Nasdaq  Stock 
Market  LLC  (Nasdaq),  we  comply  with  home  country  governance  requirements  and  certain  exemptions  thereunder  rather  than  complying 
with  Nasdaq  corporate  governance  standards.  While  we  voluntarily  follow  most  Nasdaq  corporate  governance  rules,  we  intend  to  take 
advantage of the following exemptions afforded to foreign private issuers:

• We do not intend to follow Nasdaq Rule 5620, which requires that we hold an annual general meeting of shareholders and that we 
provide  notice  thereof  to  Nasdaq.  Such  annual  general  meeting  requirement  is  not  required  under  Cayman  Islands  law  nor  our 
Eleventh  Amended  and  Restated  Memorandum  and  Articles  of  Association,  and  instead  our  board  of  directors  may  convene  an 
annual general meeting of shareholders at its discretion.

• We do not intend to follow certain provisions of Nasdaq Rule 5635, which requires shareholder approval for certain issuances of 
our securities, including: (a) issuances where the issued common stock will equal 20% or more of the number of shares of common 
stock or voting power outstanding before the issuance, except if the issuance is (i) a public offering or (ii) at a price not less than the 
greater of the book value, or the market value, of the stock; (b) issuances in connection with a stock option or purchase plan to be 
established  or  materially  amended  to  which  stock  may  be  acquired  by  officers,  directors,  employees,  or  consultants;  and  (c) 
issuances in connection with the acquisition of the stock or assets of another company that, on issuance, will equal 20% or more of 
the number of shares or voting power outstanding before such issuance. Such shareholder approval requirements are not required 
under  Cayman  Islands  law  nor  our  Eleventh  Amended  and  Restated  Memorandum  and  Articles  of  Association,  and  instead  our 
board of directors may decide to proceed with issuances under (a), (b) or (c), in its sole discretion, or if our board of directors so 
chooses, it may receive prior approval from our shareholders by ordinary resolution.

145

• We  do  not  intend  to  follow  Nasdaq  Rule  5640,  which  requires  that  voting  rights  of  existing  shareholders  of  publicly  traded 
registered common stock cannot be disparately reduced or restricted through any corporate action or issuance. Such voting rights 
are not required under Cayman Islands law nor our Eleventh Amended and Restated Memorandum and Articles of Association, and 
instead we may issue shares with rights which are preferential to those of our currently issued ordinary shares, and the rights of such 
preferred shares may include the order of, or restriction on, the voting rights of the holders thereof.

We  intend  to  follow  our  home  country  practices  in  lieu  of  the  foregoing  requirements.  Although  we  may  rely  on  home  country  corporate 
governance practices in lieu of certain of the rules in the Nasdaq Rule 5600 Series, Rule 5250(b)(3), and Rule 5250(d), we must comply with 
Nasdaq’s Notification of Noncompliance requirement (Rule 5625), and have an audit committee that satisfies Rule 5605(c)(3), consisting of 
committee members that meet the independence requirements of Rule 5605(c)(2)(A)(ii). Although we currently intend to comply with the 
Nasdaq  corporate  governance  rules  applicable  other  than  as  noted  above,  we  may  in  the  future  decide  to  use  the  foreign  private  issuer 
exemption with respect to some or all the other Nasdaq corporate governance rules.

In addition, as a foreign private issuer, we take advantage of the following exemptions from SEC reporting obligations:

•

•

Exemption from filing quarterly reports on Form 10-Q or provide current reports on Form 8-K, disclosing significant events within 
four days of their occurrence.

Exemption from Section 16 rules regarding sales of common shares by insiders, which will provide less data in this regard than 
shareholders of U.S. companies that are subject to the Exchange Act.

Accordingly, our shareholders will not have the same protections afforded to shareholders of companies that are subject to all of the corporate 
governance requirements of Nasdaq and the domestic reporting requirements of the SEC. We may utilize these exemptions for as long as we 
continue to qualify as a foreign private issuer.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

ASLAN Pharmaceuticals Limited

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ASLAN Pharmaceuticals Limited and its subsidiaries (the "Company") as 
of December 31, 2021 and 2022, the related consolidated statements of comprehensive loss, changes in equity and cash flows for each of the 
three  years  in  the  period  ended  December  31,  2022,  and  the  related  notes  (collectively,  referred  to  as  the  “financial  statements”).  In  our 
opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 
2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity 
with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's 
financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws 
and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to 
obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The 
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our 
audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion 
on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or 
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the 
amounts  and  disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant 
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide 
a reasonable basis for our opinion.

We have served as the Company's auditor since 2021.

Supplemental disclosure of cash flow information and non-cash transactions:

2.

3.

As disclosed in Note 1, the majority of shareholders agreed to the Taiwan delisting in 2020 and conversion of ordinary shares to 
Nasdaq-listed ADS on a non-cash equity transaction.
As disclosed in Notes 9 and 10, the Company’s shareholding in Jaguahr Therapeutics Pte. Ltd in April 2021 was diluted as a 
result of which, the Company’s majority controlling interest was lost. However, the Company retains significant influence and
thus the former subsidiary is recognized as an associate company (as defined in Note 4). This was accounted for as a non-cash 
equity transaction, using the equity method.
As disclosed in Note 25(c), with effect from March 13, 2023 the Company changed the ratio of the ADSs to its ordinary shares 
from one (1) ADS representing five (5) ordinary shares to one (1) ADS representing twenty-five (25) ordinary shares on a non-
cash equity transaction.

ASLAN PHARMACEUTICALS LIMITED AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 2020, 2021 AND 2022
(In U.S. Dollars, other than shares or share data, or otherwise noted)

1. NATURE OF OPERATIONS  

ASLAN Pharmaceuticals Limited (“ASLAN Cayman”) was incorporated in the Cayman Islands in June 2014 and is the listing vehicle 
for the listing on the Nasdaq Global Market sponsored with its issuance of American Depositary Shares (“ADSs”) in the United States. 
ASLAN  Cayman  and  its  subsidiaries  (collectively  referred  to  as  the  “Company”)  is  a  clinical-stage  immunology  focused 
biopharmaceutical company developing innovative treatments to transform the lives of patients. 

The Company’s portfolio is led by eblasakimab (also known as ASLAN004), a potential first-in-class human monoclonal antibody that 
binds  to  the  IL-13  receptor,  blocking  signaling  of  two  pro-inflammatory  cytokines,  IL-4  and  IL-13  which  are  central  to  triggering 
symptoms of atopic dermatitis, such as redness and itching of the skin.  

ASLAN Pharmaceuticals Pte. Ltd. was incorporated in Singapore in April 2010 and ASLAN Pharmaceuticals Limited was incorporated 
in Cayman Islands in June 2014 as the listing vehicle. The Company’s ADSs have been listed on the Nasdaq Capital Market since May 
2018 and the ordinary shares were previously listed on TPEx. In August 2020, the Company’s ordinary shares ceased trading on TPEx, 
and in September 2020, the Company’s shareholders approved the cessation of the public company status in Taiwan, resulting in Nasdaq 
being the primary listing of the Company’s securities.

On September 14, 2022, ASLAN Cayman submitted to the Listing Qualifications Department of Nasdaq an application to transfer the 
listing of its American Depositary Shares ("ADSs") representing ordinary shares of the Company from the Nasdaq Global Market to the 
Nasdaq Capital Market. On September 27, 2022, the Company received notice from Nasdaq that its application to transfer listing of its 
ADSs  had  been  approved.  The  transfer  was  effective  at  the  opening  of  business  on  September  29,  2022.  The  Company  continues  to 
trade under the symbol "ASLN."

The Company has financed its operations to date primarily through the issuance of common shares or ADSs. The Company has incurred 
net losses since inception. Please refer to Notes 14 and 25(b) for details of the Company’s fund-raising activities.

2. APPROVAL OF FINANCIAL STATEMENTS

The consolidated financial statements were approved by the Company’s board of directors on March 24, 2023.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a.

Statement of compliance

The  principal  accounting  policies  applied  in  the  preparation  of  these  consolidated  financial  statements  are  set  out  below.  These 
policies  have  been  consistently  applied  to  all  the  periods  presented,  unless  otherwise  stated.  The  accompanying  consolidated 
financial statements have been prepared in conformity with IFRS issued by the IASB. 

b. Basis of preparation

The consolidated financial statements have been prepared on the historical cost basis except for financial instruments and long-term 
incentive plan payable arising from cash-settled share-based payment arrangements which are measured at fair value.

c. Classification of current and non-current assets and liabilities

Current assets include:

1) Assets held primarily for the purpose of trading;

2) Assets expected to be realized within 12 months after the reporting period; and

3) Cash and cash equivalents unless the asset is restricted from being exchanged or used to settle a liability for at least 12 months 

after the reporting period.

Current liabilities include:

1) Liabilities held primarily for the purpose of trading;

2) Liabilities due to be settled within 12 months after the reporting period; and

F-8

 
 
 
 
 
3) Liabilities for which the Company does not have an unconditional right to defer settlement for at least 12 months after the 

reporting period. Terms of a liability that could, at the option of the counterparty, result in its settlement by the issue of equity 
instruments do not affect its classification.

Assets and liabilities that are not classified as current are classified as non-current.

d. Basis of consolidation

The  consolidated  financial  statements  include  the  financial  statements  of  ASLAN  Cayman  and  entities  controlled  by  ASLAN 
Cayman (its subsidiaries). 

The consolidated financial statements incorporate the financial statements of ASLAN Cayman and entities controlled by ASLAN 
Cayman (its subsidiaries) made up to December 31 each year. Control is achieved when the Company:

•

•

•

Has the power over the investee;

Is exposed, or has rights, to variable returns from its involvement with the investee; and

Has the ability to use its power to affects its returns.

The Company reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or 
more of the three elements of control listed above. When the Company has less than a majority of the voting rights of an investee, it 
considers that it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant 
activities of the investee unilaterally. The Company considers all relevant facts and circumstances in assessing whether or not the 
Company’s voting rights in an investee are sufficient to give it power, including:

•

•

•

•

The size of the Company’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

Potential voting rights held by the Company, other vote holders or other parties;

Rights arising from other contractual arrangements; and

Any additional facts and circumstances that indicate that the Company has, or does not have, the current ability to direct the 
relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses 
control of the subsidiary. Specifically, the results of subsidiaries acquired or disposed of during the year are included in profit or 
loss from the date the Company gains control until the date when the Company ceases to control the subsidiary.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with 
those used by the Company.

All intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between the members of the 
Company are eliminated on consolidation. 

Non-controlling  interests  in  subsidiaries  are  identified  separately  from  the  Company’s  equity  therein.  Those  interests  of  non-
controlling  shareholders  that  are  present  ownership  interests  entitling  their  holders  to  a  proportionate  share  of  net  assets  upon 
liquidation may initially be measured at fair value or at the non-controlling interests’ proportionate share of the fair value of the 
acquiree’s identifiable net assets. The choice of measurement is made on an acquisition-by-acquisition basis. Other non-controlling 
interests  are  initially  measured  at  fair  value.  Subsequent  to  acquisition,  the  carrying  amount  of  non-controlling  interests  is  the 
amount of those interests at initial recognition plus the non-controlling interests’ share of subsequent changes in equity. 

F-9

 
Profit or loss and each component of other comprehensive income are attributed to the stockholders of the Company and to the non-
controlling interests. Total comprehensive income of the subsidiaries is attributed to the stockholders of the Company and to the 
non-controlling interests even if this results in the non-controlling interests having a deficit balance.

Changes in the Company’s ownership interests in subsidiaries that do not result in the Company losing control over the subsidiaries 
are accounted for as equity transactions. The carrying amounts of the interests of the Company and the non-controlling interests are 
adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-
controlling  interests  are  adjusted  and  the  fair  value  of  the  consideration  paid  or  received  is  recognized  directly  in  equity  and 
attributed to stockholders of the Company.

When  the  Company  loses  control  of  a  subsidiary,  the  gain  or  loss  on  disposal  recognized  in  profit  or  loss  is  calculated  as  the 
difference between 

(i)

the aggregate of the fair value of the consideration received and the fair value of any retained interest and 

(ii)

the  previous  carrying  amount  of  the  assets  (including  goodwill),  less  liabilities  of  the  subsidiary  and  any  non-controlling 
interests. 

All  amounts  previously  recognized  in  other  comprehensive  income  in  relation  to  that  subsidiary  are  accounted  for  as  if  the 
Company had directly disposed of the related assets or liabilities of the subsidiary (i.e. reclassified to profit or loss or transferred to 
another category of equity as required/permitted by applicable IFRS Standards). The fair value of any investment retained in the 
former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under 
IFRS 9 when applicable, or the cost on initial recognition of an investment in an associate or a joint venture. 

Associates

An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint 
venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not 
control  or  joint  control  over  those  policies.  The  results  and  assets  and  liabilities  of  associates  are  incorporated  in  these  financial 
statements  using  the  equity  method  of  accounting,  except  when  the  investment  is  classified  as  held  for  sale,  in  which  case  it  is 
accounted for in accordance with IFRS 5 “Non-current Assets Held for Sale and Discontinued Operations”.

Under the equity method, an investment in an associate is initially recognized in the consolidated balance sheet at cost and adjusted 
thereafter  to  recognize  the  Company’s  share  of  the  profit  or  loss  and  other  comprehensive  income  of  the  associate.  When  the 
Company’s share of losses of an associate exceeds the Company’s interest in that associate (which includes any long-term interests 
that, in substance, form part of the Company’s net investment in the associate), the Company discontinues recognizing its share of 
further losses.

Additional  losses  are  recognized  only  to  the  extent  that  the  Company  has  incurred  legal  or  constructive  obligations  or  made 
payments on behalf of the associate.

An investment in an associate is accounted for using the equity method from the date on which the investee becomes an associate. 
On acquisition of the investment in an associate, any excess of the cost of the investment over the Company’s share of the net fair 
value  of  the  identifiable  assets  and  liabilities  of  the  investee  is  recognized  as  goodwill,  which  is  included  within  the  carrying 
amount of the investment. Any excess of the Company’s share of the net fair value of the identifiable assets and liabilities over the 
cost  of  the  investment,  after  reassessment,  is  recognized  immediately  in  profit  or  loss  in  the  period  in  which  the  investment  is 
acquired. 

The requirements of IAS 36 Impairment of Assets are applied to determine whether it is necessary to recognize any impairment loss 
with respect to the Company’s investment in an associate. When necessary, the entire carrying amount of the investment (including 
goodwill)  is  tested  for  impairment  in  accordance  with  IAS  36  as  a  single  asset  by  comparing  its  recoverable  amount  (higher  of 
value  in  use  and  fair  value  less  costs  of  disposal)  with  its  carrying  amount,  any  impairment  loss  recognized  forms  part  of  the 
carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that 
the recoverable amount of the investment subsequently increases.

The Company discontinues the use of the equity method from the date when the investment ceases to be an associate. When the 
Company retains an interest in the former associate and the retained interest is a financial asset, the Company measures the retained 
interest at fair value at that date and the fair value is regarded as its fair value on initial recognition in accordance with IFRS 9. The 
difference between the carrying amount of the associate at the date the equity method was discontinued, and the fair value of any 
retained interest and any proceeds from disposing of a part interest in the associate is included in the determination of the gain or 
loss on disposal of the associate. In addition, the Company accounts for all amounts previously recognized in other comprehensive 
income  in  relation  to  that  associate  on  the  same  basis  as  would  be  required  if  that  associate  had  directly  disposed  of  the  related 
assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate would be 
reclassified to profit or loss on the disposal of the related assets or liabilities, the Company reclassifies the gain or loss from equity 
to profit or loss (as a reclassification adjustment) when the associate is disposed off. 

When  the  Company  reduces  its  ownership  interest  in  an  associate,  but  the  Company  continues  to  use  the  equity  method,  the 
Company reclassifies to profit or loss the proportion of the gain or loss that had previously been recognized in other comprehensive 
income relating to that reduction in ownership interest if that gain or loss would be reclassified to profit or loss on the disposal of 
the  related  assets  or  liabilities.  When  a  Company  entity  transacts  with  an  associate  of  the  Company,  profits  and  losses  resulting 
from  the  transactions  with  the  associate  are  recognized  in  the  Company’s  consolidated  financial  statements  only  to  the  extent  of 
interests in the associate that are not related to the Company. 

See Note 9 and Note 10 for detailed information on subsidiaries and on associates respectively (including percentages of ownership 
and main businesses).

e.

Foreign currencies

Both the functional currency and reporting currency of the Company is the U.S. dollar.

Monetary  assets  and  liabilities  denominated  in  currencies  other  than  the  applicable  functional  currencies  are  translated  into  the 
functional currencies at the prevailing rates of exchange at the end of the reporting period. Nonmonetary assets and liabilities are 
remeasured  into  the  applicable  functional  currencies  at  historical  exchange  rates.  Transactions  in  currencies  other  than  the 
applicable  functional  currencies  during  the  year  are  converted  into  the  functional  currencies  at  the  applicable  rates  of  exchange 
prevailing at the dates of the transactions. Exchange differences are recognized in “other gains and losses, net” in the consolidated 
statement of comprehensive loss.

f.

Intangible assets

1)

Intangible assets acquired separately

Intangible assets with finite useful lives that are acquired separately are initially measured at cost and subsequently measured at 
cost, less accumulated amortization and accumulated impairment loss. Amortization is recognized on a straight-line basis. The 
estimated  useful  lives,  residual  values,  and  amortization  methods  are  reviewed  at  the  end  of  each  reporting  period,  with  the 
effect  of  any  changes  in  estimates  accounted  for  on  a  prospective  basis.  Intangible  assets  with  indefinite  useful  lives  that  are 
acquired separately are measured at cost, less accumulated impairment loss.

2)

Internally-generated intangible assets – research and development expenditures

Expenditure on research activities is recognized as an expense in the period in which it is incurred.

An internally-generated intangible asset arising from the development phase of an internal project is recognized only if all of the 
following have been demonstrated:

a)

b)

c)

The technical feasibility of completing the intangible asset so that it will be available for use or sale;

The intention to complete the intangible asset and use or sell it;

The ability to use or sell the intangible asset;

F-11

d)

e)

The manner in which intangible asset will generate probable future economic benefits;

The availability of adequate technical, financial and other resources to complete the development and to use or sell the 
intangible asset; and

f)

The ability to measure reliably the expenditure attributable to the intangible asset during its development.

The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date 
when an intangible asset first meets the recognition criteria listed above. Subsequent to initial recognition, they are measured on 
the same basis as intangible assets that are acquired separately.

3)

Derecognition of intangible assets

An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or 
losses  arising  from  derecognition  of  an  intangible  asset,  measured  as  the  difference  between  the  net  disposal  proceeds  and  the 
carrying amount of the asset, are recognized in profit or loss when the asset is derecognized.

g.

Impairment of tangible and intangible assets

At  the  end  of  each  reporting  period,  the  Company  reviews  the  carrying  amounts  of  its  tangible  and  intangible  assets  in  order  to 
determine  whether  there  is  any  indication  that  those  assets  have  suffered  any  impairment  loss.  If  any  such  indication  exists,  the 
recoverable  amount  of  an  asset  is  estimated  in  order  to  determine  the  extent  of  the  impairment  loss.  When  it  is  not  possible  to 
estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit 
to which the asset belongs.

Intangible assets with indefinite useful lives and intangible assets not yet available are not subject to amortization, but are tested 
annually  for  impairment  or  more  frequently  if  there  are  indicators  of  impairment.  In  respect  of  the  impairment  indicators,  the 
Company considers both internal and external sources of information to determine whether an asset may be impaired, which may 
include  the  significant  underperformance  of  the  business  in  relation  to  expectations,  significant  negative  industry  or  economic 
trends, and significant changes or planned changes with adverse effects in the use of the assets, as well as the internal reporting 
which  indicates  the  economic  performance  of  an  asset  is  worse  than  expected.  If  any  such  indicators  exist,  the  Company  will 
estimate the recoverable amount of such indefinite-lived intangible asset and compare it with its carrying amount.

The recoverable amount is the higher of fair value less costs of disposal and value in use. If the recoverable amount of an asset or 
cash-generating  unit  is  estimated  to  be  less  than  its  carrying  amount,  the  carrying  amount  of  the  asset  or  cash-generating  unit  is 
reduced to its recoverable amount, with the resulting impairment loss recognized in profit or loss.

When  an  impairment  loss  is  subsequently  reversed,  the  carrying  amount  of  the  corresponding  asset  or  cash-generating  unit  is 
increased  to  the  revised  estimate  of  its  recoverable  amount,  but  only  to  the  extent  of  the  carrying  amount  that  would  have  been 
determined had no impairment loss been recognized on the asset or cash-generating unit in prior years. A reversal of an impairment 
loss is recognized in profit or loss.

h.

Financial instruments

Financial assets and financial liabilities are recognized when a Company entity becomes a party to the contractual provisions of the 
instruments.

Financial  assets  and  financial  liabilities  are  initially  measured  at  fair  value.  Transaction  costs  that  are  directly  attributable  to  the 
acquisition or issuance of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value 
through profit or loss (i.e., FVTPL)) are added to or deducted from the fair value of the financial assets or financial liabilities, as 
appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities 
at FVTPL are recognized immediately in profit or loss.

F-12

1) Financial asset

All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis.

a) Measurement categories

Financial assets are classified into the following categories: Financial assets at FVTPL, financial assets at amortized cost 
and equity instruments at fair value through other comprehensive income (i.e., FVTOCI).

i.

Financial assets at FVTPL

Money market funds are classified as FVTPL as they do not meet the conditions to be classified as amortized cost or 
FVTOCI.

Financial assets at FVTPL are subsequently measured at fair value, with any gains or losses arising on remeasurement 
recognized in other gains or losses.

ii.

Financial assets at amortized cost

A financial asset shall be measured at amortized cost if both of the following conditions are met:

i)

The financial asset is held within a business model whose objective is to hold financial assets in order to collect 
contractual cash flows; and

ii) The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of 

principal and interest on the principal amount outstanding.

For the financial assets measured at amortized cost (including cash and cash equivalents and refundable deposits), the 
Company  applies  the  effective  interest  method  to  the  gross  carrying  amount  at  amortized  cost  less  any  impairment 
from initial recognition. Any foreign exchange gains and losses are recognized in profit or loss.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of such a financial 
asset. Short-term investments have been purchased during the year and have matured before the end of the year. These 
have been assessed to be financial assets held at amortized cost. Interest accretion income on short-term investment is 
recognized in profit or loss and as part of "Other Income" line item.

Cash  equivalents  include  time  deposits  and  money  markets  funds,  which  are  highly  liquid,  readily  convertible  to  a 
known amount of cash and are subject to an insignificant risk of changes in value. These cash equivalents are held for 
the purpose of meeting short-term cash commitments.

iii.

Investments in equity instruments at FVTOCI

On initial recognition, the Company may make an irrevocable election to designate investments in equity instruments 
as  at  FVTOCI.  Designation  as  at  FVTOCI  is  not  permitted  if  the  equity  investment  is  held  for  trading  or  if  it  is 
contingent consideration recognized by an acquirer in a business combination.

Investments in equity instruments at FVTOCI are subsequently measured at fair value with gains and losses arising 
from  changes  in  fair  value  recognized  in  other  comprehensive  income  and  accumulated  in  other  equity.  The 
cumulative gain or loss will not be reclassified to profit or loss on disposal of the equity investments; instead, it will 
be transferred to retained earnings.

Dividends  on  these  investments  in  equity  instruments  are  recognized  in  profit  or  loss  when  the  Company’s  right  to 
receive  the  dividends  is  established,  unless  the  dividends  clearly  represent  a  recovery  of  part  of  the  cost  of  the 
investment.

F-13

Fair value hierarchy levels 1 to 3 are based on the degree to which the fair value is observable:

• Level  1  fair  value  measurements  are  those  derived  from  quoted  prices  (unadjusted)  in  active  markets  for  identical 

assets or liabilities;

• Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that 

are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level  3  fair  value  measurements  are  those  derived  from  valuation  techniques  that  include  inputs  for  the  asset  or 

liability that are not based on observable market data (unobservable inputs).

b)

Impairment of financial assets

The Company recognizes a loss allowance for expected credit losses on financial assets at amortized cost.

For  financial  instruments,  the  Company  recognizes  lifetime  expected  credit  losses  (i.e.,  ECLs)  when  there  has  been  a 
significant increase in credit risk since initial recognition. If, on the other hand, the credit risk on a financial instrument has 
not increased significantly since initial recognition, the Company measures the loss allowance for that financial instrument 
at an amount equal to 12-month ECLs.

Expected  credit  losses  reflect  the  weighted  average  of  credit  losses  with  the  respective  risks  of  default  occurring  as  the 
weights.  Lifetime  ECLs  represent  the  expected  credit  losses  that  will  result  from  all  possible  default  events  over  the 
expected life of a financial instrument. In contrast, 12-month ECLs represent the portion of lifetime ECLs that is expected 
to result from default events on a financial instrument that are possible within 12 months after the reporting date.

The Company recognizes an impairment gain or loss in profit or loss for all financial instruments with a corresponding 
adjustment to their carrying amount through a loss allowance account.

c)

Derecognition of financial assets

The Company derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire or 
when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another party.

On derecognition of a financial asset at amortized cost in its entirety, the difference between the asset’s carrying amount 
and the sum of the consideration received and receivable is recognized in profit or loss. On derecognition of an investment
in an equity instrument at FVTOCI, the difference between the asset’s carrying amount and the sum of the consideration 
received and receivable is recognized in profit or loss, and the cumulative gain or loss which had been recognized in other 
comprehensive income is transferred directly to retained earnings, without recycling through profit or loss.

2) Equity instruments

Debt and equity instruments issued by the Company entity are classified as either financial liabilities or as equity in accordance 
with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument.

Equity instruments issued by the Company entity are recognized at the proceeds received, net of direct issue costs.

No gain or loss is recognized in profit or loss on the issuance of the Company’s own equity instruments.

F-14

3) Financial liabilities

a) Subsequent measurement

Except the following situations, all financial liabilities are measured at amortized cost using the effective interest method:

1) Financial liabilities at FVTPL

Financial liabilities are classified as at FVTPL when such financial liabilities are either held for trading or are designated 
as at FVTPL.

Financial  liabilities  held  for  trading  are  stated  at  fair  value,  and  any  gains  or  losses  on  such  financial  liabilities  are 
recognized in other gains or losses.

Fair value is determined in the manner described in Note 22.

b) Derecognition of financial liabilities

The difference between the carrying amount of a financial liability derecognized and the consideration paid and payable, 
including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.

When the Company exchanges with the existing lender one debt instrument into another one with substantially different 
terms, such exchange is accounted for as an extinguishment of the original financial liability and the recognition of a new 
financial liability. Similarly, the Company accounts for substantial modification of terms of an existing liability or part of it 
as an extinguishment of the original financial liability and the recognition of a new liability. It is assumed that the terms are 
substantially different if the discounted present value of the cash flows under the new terms, including any fees paid net of 
any  fees  received  and  discounted  using  the  original  effective  rate  is  at  least  10  per  cent  different  from  the  discounted 
present  value  of  the  remaining  cash  flows  of  the  original  financial  liability.  If  the  modification  is  not  substantial,  the 
difference between: (1) the carrying amount of the liability before the modification; and (2) the present value of the cash 
flows after modification is recognized in profit or loss as the modification gain or loss within other gains and losses.

4) Compound instruments 

The  component  parts  of  compound  instruments  issued  by  the  Company  are  classified  separately  as  financial  liabilities  and 
equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity 
instrument. A component part that will be settled by the exchange of a fixed amount of cash or another financial asset for a 
fixed number of the Company’s own equity instruments is an equity instrument.

At the date of issue, the fair value of the liability component is estimated using the prevailing market interest rate for similar 
non-convertible  instruments.  This  amount  is  recorded  as  a  liability  on  an  amortized  cost  basis  using  the  effective  interest 
method until extinguished upon conversion or upon the instrument’s maturity date.

5) Derivative financial instruments

Derivatives  embedded  in  non-derivative  host  contracts  that  are  not  financial  assets  that  is  within  the  scope  of  IFRS  9  (e.g. 
financial  liabilities)  are  treated  as  separate  derivatives  when  they  meet  the  definition  of  a  derivative;  their  risks  and 
characteristics are not closely related to those of the host contracts; and the host contracts are not measured at FVTPL. The 
derivatives are measured at FVTPL (Note 13(b)).

i.

Research and development expenses

Elements of research and development expenses primarily include:

1) Payroll and other related costs of personnel engaged in research and development activities;

F-15

 
 
2) Costs related to preclinical testing of the Company’s technologies under development and clinical trials, such as payments to 
contract research organizations (“CROs”), investigators and clinical trial sites that conduct the Company’s clinical studies;

3) Costs to develop the product candidates, including raw materials, supplies and product testing related expenses; and

4) Other research and development expenses.

Research  and  development  expenses  are  expensed  as  incurred  when  these  expenditures  relate  to  the  Company’s  research  and 
development  services  and  have  no  alternative  future  uses.  The  conditions  enabling  the  capitalization  of  development  costs  as  an 
asset have not yet been met and, therefore, all development expenditures are recognized in profit or loss when incurred.

j.

Share-based payment arrangements

Equity-settled share-based payments to employees are measured at the fair value of the equity instruments at the grant date.

The  fair  value  determined  at  the  grant  date  of  the  employee  share  options  is  expensed  on  a  straight-line  basis  over  the  vesting 
period, based on the Company’s estimate of the number of employee share options that will eventually vest, with a corresponding 
increase in “capital surplus - share options reserve”. The fair value determined at the grant date of the employee share options is 
recognized as an expense in full at the grant date when the share options granted vest immediately.

At the end of each reporting period, the Company revises its estimate of the number of employee share options expected to vest. 
The  impact  of  the  revision  of  the  original  estimates  is  recognized  in  profit  or  loss  such  that  the  cumulative  expense  reflects  the 
revised estimate, with a corresponding adjustment to the capital surplus.

The  fair  value  of  the  amount  payable  to  beneficiaries  in  respect  of  bonus  entitlement  unit  grants,  which  are  settled  in  cash,  is 
recognized  as  an  expense  with  a  corresponding  increase  in  liabilities,  over  the  period  during  which  the  beneficiaries  become 
unconditionally entitled to payment. The amount is remeasured at each reporting date and at settlement based on the fair value of 
the bonus entitlement units. Any changes in the liability are recognized in profit or loss.

Modification of the terms on which equity instruments were granted may have an effect on the expense that will be recorded. In 
accordance  with  IFRS  2,  modifications  also  apply  to  instruments  modified  after  their  vesting  date.  If  the  fair  value  of  the  new 
instruments  is  more  than  the  fair  value  of  the  old  instruments  (e.g.  by  reduction  of  the  exercise  price  or  issuance  of  additional 
instruments), the incremental amount is recognized over the remaining vesting period in a manner similar to the original amount. If 
the  modification  occurs  after  the  vesting  period,  the  incremental  amount  is  recognized  immediately.  If  the  fair  value  of  the  new
instruments is less than the fair value of the old instruments, the original fair value of the equity instruments granted is expensed as 
if the modification never occurred.

k. Taxation

The provision for income tax recognized in profit or loss comprises current and deferred tax. Current tax is income tax paid and 
payable for the current year based on the taxable profit of the year and any adjustments to tax payable (or receivable) in respect of
prior years. Deferred tax is accounted for using the balance sheet liability method in respect of temporary differences arising from 
differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax basis used in 
the  computation  of  taxable  profit  or  loss.  Deferred  tax  assets  are  recognized  to  the  extent  that  it  is  probable  that  future  taxable 
profits will be available against which the temporary differences can be utilized. The carrying amount is reviewed at the end of each 
reporting period on the same basis. Deferred tax is measured at the tax rates that are expected to apply in the period in which the 
asset or liability is settled, based on tax rates that have been enacted or substantively enacted by the end of the reporting period.

F-16

l. Cash and short-term deposits

Cash and short-term deposits in the statement of financial position comprise cash at banks and on hand and short-term highly liquid 
deposits  with  a  maturity  of  three  months  or  less,  that  are  readily  convertible  to  a  known  amount  of  cash  and  subject  to  an 
insignificant risk of changes in value. For the purpose of the consolidated statement of cash flows, cash and cash equivalents consist 
of cash, short-term deposits and money market fund, as defined above, as they are considered an integral part of the Company’s 
cash management.

5. CRITICAL ACCOUNTING JUDGMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY

In applying the Company’s accounting policies, which are described in Note 4, the directors are required to make judgements (other 
than  those  involving  estimations)  that  have  a  significant  impact  on  the  amounts  recognized  and  to  make  estimates  and  assumptions 
about  the  carrying  amounts  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  The  estimates  and  associated 
assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these 
estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the 
period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the 
revision affects both current and future periods.

Critical judgements and estimation in applying the Company’s accounting policies

Key Sources of Critical Judgements

The  below  are  the  instances  of  application  of  critical  judgement  which  are  expected  to  have  a  significant  effect  on  the  amounts 
recognized in the financial statements.

Dilution of subsidiary and recognition of associate 

As further described in Note 9, on April 28, 2021, the Company’s shareholding in Jaguahr Therapeutics Pte. Ltd (“JAGUAHR”) was 
diluted from 55% to 35% resulting in a loss of control. The Company retains the right to offer to purchase, and, upon valid exercise to 
buy back all or part of the equity held by Bukwang at a price equal to three times the amount invested by Bukwang upon receiving 
Bukwang’s  acceptance  notice  which  are  deemed  potential  voting  rights.  Given  that  JAGUAHR  is  at  an  early  stage  of  product 
development,  the  Company  has  assessed  that  the  potential  voting  rights  are  not  considered  substantive,  and  thus  JAGUAHR  has  not 
been consolidated as of December 31, 2021, and 2022.

Key Sources of Estimation Uncertainty

The  below  are  the  critical  accounting  estimates,  that  the  directors  have  made  in  the  process  of  applying  the  Company’s  accounting 
policies and that have the most significant effect on the amounts recognized in financial statements.

Fair value measurements and valuation processes

Some  of  the  Company’s  assets  and  liabilities  are  measured  at  fair  value  for  financial  reporting  purposes.  The  Head  of  Finance  is 
responsible to determine the appropriate valuation techniques and inputs for fair value measurements. In estimating the fair value of an 
asset or a liability, the Company uses market-observable data to the extent it is available. Where Level 1 inputs are not available, the 
Company engages third party qualified valuers to assist in performing the valuation. The senior management team reports to the board 
of directors of the Company quarterly to explain the cause of fluctuations in the fair value of the assets and liabilities.

The  valuations  of  the  Company’s  assets  and  liabilities  that  are  measured  at  fair  value  are  sensitive  to  changes  in  one  or  more 
unobservable  inputs  which  are  considered  reasonably  possible  within  the  next  financial  year.  Further  information  on  the  carrying 
amounts of these assets and the sensitivity of those amounts to changes in unobservable inputs are provided in Note 22.

In  February  2022,  the  Company  engaged  an  asset  management  bank  to  obtain  better  returns  on  the  Company’s  cash  pursuant  to 
Company’s Investment Policy which is designed to permit the Company to earn an attractive rate and return on its investments while 
limiting the risk, conserve capital and maintain liquidity. The Company classifies all highly liquid investments with stated maturities of 
three months or less from date of purchase as cash equivalents as they were subject to an insignificant risk of changes in value. The 
money market fund is highly liquid and invested in quality short-term money market instruments and is readily convertible to a known 
amount of cash that is subject to an insignificant risk of change. The Company discloses gains arising from such investments as cash 
flows arising from investing activities in the cash flow statement consistently.

JAGUAHR's accounting from subsidiary to associate

On October 15, 2019, the Company established a joint venture with Bukwang Pharmaceutical Co., Ltd., a leading research and 
development  focused  Korean  pharmaceutical  company,  to  develop  antagonists  of  the  aryl  hydrocarbon  receptor  (AhR).  The 
Company at inception owned a controlling stake 55% of the entity, which is called Jaguahr Therapeutics Pte. Ltd. The Company 
transferred the global rights to all of the assets related to AhR technology, into Jaguahr Therapeutics Pte. Ltd (“JAGUAHR”). 
Subject to the fulfilment of certain conditions, Bukwang agreed to invest $5.0 million in JAGUAHR in two tranches to fund the 
development of the assets, identify a lead development compound and file an Investigational New Drug (IND) application (JV 
Agreement). The first tranche of $2.5 million was received by JAGUAHR from Bukwang in October 2019.

On April 28, 2021, the second tranche of $2.5 million was received from Bukwang which diluted the Company's shareholding to 
35%  from  55%,  resulting  in  loss  of  control  over  the  subsidiary.  The  Company  has  retained  a  significant  influence  over 
JAGUAHR,  resulting  in  an  equity  accounted  associate  being  recognized.  A  gain  on  dilution  of  subsidiary  of  $2,307,735 
representing  the  reclassification  of  the  capital  reserve  of  $1,376,349,  being  the  initial  reserve  set  up  upon  formation  of  the 
subsidiary, non-controlling interest derecognized of $31,717 at the date of dilution and 35% of the fair value of net identifiable 
assets of JAGUAHR at the date of the dilution being recognized for the year ended December 31, 2021.

Until  the  IND  application  is  filed,  ASLAN  Pharmaceuticals  Pte.  Ltd.  retains  the  right  to  offer  to  purchase,  and,  upon  valid 
exercise to buy back all or part of the equity held by Bukwang at a price equal to three times the amount invested by Bukwang 
upon receiving Bukwang’s acceptance notice. Given that JAGUAHR is at an early stage of product development, the Company 
has assessed that the value of the right as $0.

Jaguahr Therapeutics Pte. Ltd. is no longer the Company’s consolidated subsidiary as of December 31, 2021, and 2022. Please

b. Other long-term borrowings (secured)

Loan and Security Agreement with K2 HealthVentures

On July 12, 2021, ASLAN Pharmaceuticals Limited (the “ASLAN Cayman”) and ASLAN Pharmaceuticals (USA) Inc. as borrowers 
entered  into  a  Loan,  Guaranty,  and  Security  Agreement  (the  “K2HV  Loan  Agreement”)  with  K2  HealthVentures  LLC  (“K2HV”)  as 
administrative agent, and Ankura Trust Company, LLC as collateral agent. The borrowers’ obligations under the Loan Agreement are 
guaranteed  by  ASLAN  Pharmaceuticals  Pte.  Ltd  (“ASLAN  Singapore”)  and  any  future  material  subsidiaries  and  secured  by 
substantially  all  of  ASLAN  Cayman’s,  ASLAN  Singapore’s  and  any  future  subsidiary  guarantors’  assets,  other  than  intellectual 
property. 

The K2HV Loan Agreement provides for up to $45.0 million of term loans, consisting of (i) the first tranche of $20.0 million available 
at closing, (ii) the second and third traches in the aggregate amount of $10.0 million subject to the Company’s achievement of certain 
clinical milestones related to farudodstat and eblasakimab and (iii) an uncommitted fourth tranche of up to $15.0 million.

The term loans bear interest at a floating rate equal to the greater of (i) the prime rate published by Wall Street Journal plus 5.00% or (ii) 
8.25% per annum. The monthly payments are interest-only until August 1, 2023, which may be extended to August 1, 2024, upon the 
Company’s achievement of certain clinical milestones. Subsequent to the interest-only period, the term loans will be payable in equal 
monthly installments of principal plus accrued and unpaid interest, through the maturity date which is July 1, 2025. The Company paid 
the lenders a one-time $255,000 facility fee at closing and will be obligated to pay for an additional facility fee equal to 0.85% of any 
term loans borrowed under the fourth tranche. In addition, the Company is obligated to pay a final payment fee of 6.25% of the original 
principal amount of the term loans at the maturity date. The Company may elect to prepay all, but not less than all, of the term loans 
prior  to  the  term  loan  maturity  date,  subject  to  a  prepayment  fee  of  up  to  3.0%  of  the  then  outstanding  principal  balance.  After 
repayment, no term loans may be borrowed again.

On July 12, 2021, the full first tranche of $20.0 million available at closing was drawn down. Due to the K2 Warrant described below, 
the fair value of the first tranche loan on July 12, 2021, was $19,311,676. Subsequent to the interest-only period from July 1, 2021, to 
July 31, 2023, the term loans will be payable in equal monthly instalments of principal plus accrued and unpaid interest, through the 
maturity date which is July 1, 2025. However, the interest-only period can be extended up to 36 months from the loan closing upon 
announcement of the achievement of positive data for the Company’s Phase 2b clinical study of eblasakimab in atopic dermatitis which 
is supportive of continued clinical advancement with a commercially viable product profile, as determined by K2HV in its reasonable 
discretion.

Borrowings under the K2HV Facility are secured with a pledge of the borrowers’ equity interests in subsidiaries and collateral over all 
of  the  Company’s  cash,  goods,  and  other  personal  property,  with  the  exception  of  (i)  the  Company’s  registered  intellectual  property 
assets, (ii) personal property to the extent that granting of security over any such personal property would constitute a breach of or result 
in the termination of, or require any consent not obtained under, any license, agreement, instrument or other document evidencing or 
giving  rise  to  such  property,  or  is  otherwise  prohibited  by  any  requirement  of  law,  and  (iii)  the  Company’s  equity  interests  in 
JAGUAHR. Such pledge and collateral may be enforced only if there has been an event of default as stipulated in the loan agreement. 
As  of  December  31,  2021,  and  2022,  the  Company  is  in  full  compliance  with  the  loan  agreement  and  there  have  been  no  events  of 
default. 

In  connection  with  the  closing  of  the  loan  facility,  the  Company  issued  a  warrant  to  purchase  ordinary  shares  (the  “K2  Warrant”)  to 
K2HV. The number of ordinary shares exercisable under the K2 Warrant equals (i) 2.95% of the aggregate term loan advances made to 
the Company from time to time divided by (ii) the warrant price of $0.5257 per ordinary share (equivalent to $2.6285 per ADS). The K2 
Warrant also includes a cashless exercise feature allowing the holder to receive shares underlying the warrant in an amount reduced by 
the aggregate exercise price that would have been payable upon exercise of the warrant for such shares. The K2 Warrant is exercisable 
until its expiration on July 12, 2031. The total proceeds attributed to the K2 Warrant was approximately $688,324 based on the relative 
fair  value  as  of  the  date  of  the  drawdown.  As  the  number  of  ADS  to  be  issued  under  the  cashless  method  will  continue  to  vary 
dependent to the share price of the Company, the K2 Warrants do not meet the equity classification and are classified as liability and fair 
valued though profit or loss. 

On January 5, 2022, the Company drew down the second tranche $5 million in full of the loan facility provided by K2HV pursuant to 
the Loan Agreement. The second tranche milestone was completed, and the full funds were received on February 4, 2022. As a result of 
the drawdown of the second tranche of the loan facility, the number of ordinary shares exercisable under the K2 Warrant increased to 
1,402,891 (representing 280,578 ADS), based on the 2.95% coverage of the total drawdown facility $25 million, being the aggregate 
term loan advances at that date, divided by the warrant price of $0.5257 per ordinary share (equivalent to $2.6285 per ADS).

As of December 31, 2022, the fair value of the K2 Warrant was revalued to $90,213 with the difference of $133,139 (Note 16(b)) being 
recorded to the profit or loss. See Note 22 for more detail on assumptions used in the valuation of the K2 warrant. As of December 31, 
2022, K2HV did not exercise any warrants.

15. MATERIAL LICENSE AGREEMENTS

Almirall

In 2012, the Company originally entered into a global licensing agreement with Almirall to develop DHODH inhibitor, LAS186323, 
which  the  Company  refers  to  as  farudodstat,  for  rheumatoid  arthritis  (excluding  any  topical  formulation),  without  upfront  payments. 
Under  the  license  agreement,  the  Company  agreed  to  fund  and  develop  farudodstat  to  the  end  of  Phase  2  through  a  development 
program.

F-25

 
 
The original license agreement was replaced by a new agreement, executed in December 2015 and amended in March 2018, granting an
exclusive,  worldwide  license  to  develop,  manufacture  and  commercialize  farudodstat  products  for  all  human  diseases,  excluding 
topically-administered products embodying the compound for keratinocyte and hyperproliferative disorders, and the non-melanoma skin 
cancers  basal  cell  carcinoma,  squamous  cell  carcinomas  and  Gorlin  Syndrome.  Under  the  license  agreement,  Almirall  is  eligible  to 
receive milestone payments and royalties based on the sales generated by the Company and/or sublicensees. As of December 31, 2022, 
the Company did not accrue for the above contingent payments since the milestones have not yet been achieved.

CSL

The  Company  entered  into  a  global  license  agreement  with  CSL  Limited  (“CSL”),  in  May  2014,  to  develop  the  anti-IL13  receptor 
monoclonal antibody, CSL334 (which the Company refers to as eblasakimab) and antigen binding fragments thereof, for the treatment, 
diagnosis or prevention of diseases or conditions in humans, without upfront payments. This license agreement was amended in May 
31, 2019, pursuant to which the Company obtained an exclusive, worldwide license to certain intellectual property owned or licensed by 
CSL,  including  patents  and  know-how,  to  develop,  manufacture  for  clinical  trials  and  commercialize  eblasakimab  for  the  treatment, 
diagnosis or prevention of diseases or conditions in humans. The Company’s development under such agreement is currently focused on 
the treatment of respiratory and inflammatory conditions, and in particular, atopic dermatitis.

Under  the  amended  agreement,  the  Company  is  generally  obligated  to  use  diligent  efforts  to  develop  eblasakimab  products  in 
accordance  with  the  development  plan,  to  obtain  marketing  approvals  for  eblasakimab  products  worldwide  and  to  commercialize 
eblasakimab products, either by itself or through sublicensees.

In consideration of the rights granted to the Company under the amended agreement, the Company will make a first payment of $30 
million  to  CSL  upon  commencement  of  a  Phase  3  clinical  trial  of  eblasakimab.  The  Company  will  also  be  required  to  pay  up  to  an 
aggregate  of  $95  million  to  CSL  if  certain  regulatory  milestones  are  achieved,  up  to  an  aggregate  of  $655  million  if  certain  sales 
milestones are achieved and tiered royalties on net sales of eblasakimab products ranging between a mid-single digit percentage and 
10%.  The  Company  is  also  responsible  for  all  payments  to  third-party  licensors  to  CSL,  to  the  extent  such  obligations  relate  to  the

2020 Equity Incentive Plan

On December 10, 2020, the Board of Directors (the “Board”) of the Company approved the Company’s 2020 Equity Incentive Plan (the 
“2020 EIP”). The 2020 EIP, among other things, provides for the grant of restricted stock awards, stock options and other equity-based 
awards to employees, officers, directors and consultants. The vesting period is up to four years or determination that a different vesting 
schedule shall apply, subject to discretion of Administrator. If the options remain unexercised after a period of ten years from the date of 
grant, the options expire. Options are forfeited if the employee leaves the Company before the options vest.

The  maximum  number  of  ordinary  shares  that  may  be  issued  under  the  2020  EIP  was  originally  20,676,974  ordinary  shares  (an 
equivalent of 4,135,395 ADS of the Company, each ADS representing five ordinary shares. As discussed in Note 25(c), the ratio will 
change from March 10, 2023.) On December 15, 2020, and during the year ended December 31, 2021, 3,824,062 and 282,000 options 
were granted under the Company’s 2020 EIP, respectively. Each option entitles the holder to subscribe for one ADS of the Company. 
The options granted are valid for 10 years. No performance conditions were attached to the plan. No more than 62,030,922  ordinary 
shares (an equivalent of 12,406,184 ADSs) may be issued under the 2020 EIP upon the exercise of incentive stock options. In addition, 
the  number  of  ordinary  shares  reserved  for  issuance  under  the  2020  EIP  will  automatically  increase  on  January  1  of  each  year, 
commencing  on  January  1,  2022,  and  ending  on  (and  including)  January  1,  2030,  in  an  amount  equal  to  4%  of  the  total  number  of 
ordinary shares outstanding on December 31 of the preceding calendar year. The Board may act prior to January 1 of a given year to 
provide that there will be no increase for such year or that the increase for such year will be a lesser number of ordinary shares. 

In connection with the approval of the 2020 EIP, the Board determined that there will be no increase for January 1, 2021. The Board 
determined  that  there  will  be  an  evergreen  options  increase  of  13,948,935  shares  options  (an  equivalent  of  2,789,787  ADS)  for  both 
January 1, 2022, and January 1, 2023 in the amount equal to 4% of the total outstanding share options as of December 31, 2021, among 
which 8,875,745 shares options (an equivalent of 1,775,149 ADS) had been granted on January 1, 2022, and 3,590,000 ordinary shares 
(an equivalent of 718,000 ADS) had been granted on July 1, 2022. If an award under the 2020 EIP, expires, lapses or is terminated, 
exchanged for cash, surrendered, repurchased, cancelled without having been fully exercised, forfeited or is withheld to satisfy a tax 
withholding obligation in connection with an award or to satisfy a purchase or exercise price of an award, any unused shares subject to 
the award will, as applicable, become or again be available for new grants under the 2020 EIP. Awards granted under the 2020 EIP in 
substitution for any options or other equity or equity-based awards granted by an entity before the entity’s merger or consolidation with 
the Company or the Company’s acquisition of the entity’s property or stock will not reduce the number of ordinary shares available for 
grant  under  the  2020  EIP,  but  will  count  against  the  maximum  number  of  ordinary  shares  that  may  be  issued  upon  the  exercise  of 
incentive stock options. References in this summary to ordinary shares include an equivalent number of the Company’s ADSs.

In July 2022, the Remuneration Committee of the Board noted that the exercise price of options previously granted to certain officers 
and employees of the Company significantly exceeded the current fair market value of the underlying ADS (the “Underwater Options”). 
In accordance with its powers authorized under the 2020 EIP, the Remuneration Committee therefore resolved to lower the per ADS 
exercise price of the Underwater Options, believing this to be in the best interests of the Company and its shareholders to motivate and 
restore incentives for the holders of the Underwater Options. It thus resolved to amend each Underwater Option to reduce the exercise 
price of each to $0.52 per ADS for the 2020 EIP, being the Fair Market Value of the Company’s ADSs effective on the closest trading 
day  to  the  date  of  the  resolution.  The  incremental  fair  value  of  $240,835  will  be  recognized  as  an  expense  over  the  period  from  the 
modification date to the end of vesting period. The expense for the original option grant will be recognized as if the terms has not been 
modified. The fair value of the modified options was determined using the same models and principles as described above.

Information on employee share options granted under the 2020 EIP is as follows. Each option entitles the holder to subscribe for one 
ADS of the Company:

Long Term Incentive Plan

The Company maintains the Senior Management Team (SMT) Long Term Incentive Plans (LTIP), pursuant to which bonus entitlement 
unit awards were granted in 2017, 2018, and 2019. On August 23, 2017, and February 1, 2018, the Company granted 1,462,000 and 
104,000  ordinary  shares  (equivalent  to  292,400  ADS  and  20,800  ADS)  bonus  entitlement  units  to  the  Company’s  executive  officers 
pursuant  to  the  2017  LTIP,  respectively.  On  July  30,  2018,  the  Company  granted  241,142  bonus  entitlement  units  to  the  executive

and on July 30, 2019, the Company granted 491,020 bonus entitlement units to the executive officers pursuant to the 2019 LTIP.

Upon vesting and redemption, each unit award is converted into a cash payment equal to the number of units multiplied by the per-share 
fair market value of the Company’s ordinary shares on the day following the Company’s receipt of a redemption notice. The 292,400 
bonus entitlement units granted under the 2017 LTIP will be one-third vested each year after the first, second, and third anniversary of 
the award. The 20,800 bonus entitlement units granted under the 2017 LTIP will be one-half vested each year after the second and third 
anniversary of the award. The 241,142 bonus entitlement units granted under the 2018 LTIP will be one-third vested each year after the 
first, second, and third anniversary of the award. The 491,020 bonus entitlement units granted under the 2019 LTIP will be one-third 
vested each year after the first, second, and third anniversary of the award. 

To date, 283,501 units have been forfeited as of December 31, 2021, and December 31, 2022. The quoted fair value on the reporting 
date is based on the closing price per ADS of $1.12 and $0.36 as of December 31, 2021, and December 31, 2022, respectively.

The LTIPs qualify as cash-settled share-based payment transactions. The Company recognizes the liabilities in respect of its obligations 
under the LTIPs, which are measured based on the Company’s quoted market price of its ADSs at the reporting date, and takes into 
account the extent to which the services have been rendered to date.

The  Company  recognized  total  benefit  of  $467,134  in  2022  and  recognized  total  (expenses)  benefits  of  ($213,636)  and  $234,761  in 
respect  of  the  LTIPs  for  the  years  ended  December  31,  2020,  and  2021.  As  of  December  31,  2021,  and  December  31,  2022,  the 
Company recognized compensation liabilities of $701,582 and $234,448 as other payables (Note 12).

There were no transfers among Levels 1, 2 and 3 in the current and prior year.

The ending value of Money Market Fund $30,445,339 comprised of the original investment cost of $30,092,194 and the fair value 
gains resulting from interest income of $353,145.

2) Valuation techniques and inputs applied for Level 3 fair value measurement

a) As  of  December  31,  2022,  the  fair  value  of  the  Level  3  instrument  was  the  derivative  financial  liabilities  –  K2HV 
warrants. The fair values of warrants are determined using option pricing models where the significant unobservable input 
is historical volatility. An increase in the historical volatility used in isolation would result in an increase in the fair value. 
The historical volatility used for valuation was 160.3% and 132.9%, during the year of 2021 and 2022, respectively.

Sensitivity analysis

The Company is mainly exposed to the Singapore Dollar.

The  following  table  details  the  Company’s  sensitivity  to  a  5%  decrease  in  the  U.S.  dollar  against  the  relevant  foreign 
currency. The rate of 5% is the sensitivity rate used when reporting foreign currency risk internally to key management 
personnel  and  represents  management’s  assessment  of  the  reasonably  possible  change  in  foreign  exchange  rates.  The 
sensitivity  analysis  includes  only  outstanding  foreign  currency  denominated  monetary  items.  A  negative  number  below 
indicates  an  increase  in  pre-tax  loss  where  the  U.S.  dollar  weakens  5%  against  the  relevant  currency.  For  a  5% 
strengthening of the U.S. dollar against the relevant currency, there would be an equal and opposite impact on pre-tax loss.

* This is mainly attributable to the exposure to outstanding deposits in banks (not including money market funds as that is 
in US dollars) and loans in foreign currency at the end of the reporting period.

b)

Interest rate risk

The Company is exposed to interest rate risk because entities in the Company borrowed funds at fixed baseline interest 
plus floating interest rates.

The sensitivity analysis below is determined based on the Company’s exposure to interest rates for investment in money 
market fund and fixed rate borrowings at the end of the reporting period, and is prepared assuming that the amounts of
liabilities outstanding at the end of the reporting period are outstanding for the whole year. A 100-basis point increase or
decrease is used when reporting interest rate risk internally to key management personnel and represents management’s 
assessment of the reasonably possible change in interest rates. 

If interest rates had been 100 basis points higher and all other variables were held constant, the Company’s pre-tax loss for 
the  years  ended  December  31,  2020,  2021  and  2022,  would  have  increased  by  $194,378,  $308,573  and  $69,596, 
respectively.

2) Credit risk

Credit  risk  refers  to  the  risk  that  a  counterparty  will  default  on  its  contractual  obligations  resulting  in  a  financial  loss  to  the 
Company. The Company adopted a policy of only dealing with creditworthy counterparties and financial institutions, where 
appropriate, as a means of mitigating the risk of financial loss from defaults. 

3) Liquidity risk

The  Company  manages  liquidity  risk  by  monitoring  and  maintaining  a  level  of  cash  and  cash  equivalents  that  are  deemed 
adequate to finance the Company’s operations and mitigate the effects of fluctuations in cash flows. In addition, management 
monitors the utilization of long-term borrowings and ensures compliance with repayment conditions. 

As  the  Company  is  in  the  research  and  development  phase,  the  Company  will  be  seeking  future  funding  based  on  the 
requirements  of  its  business  operations.  The  Company  is  able  to  exercise  discretion  and  flexibility  to  deploy  its  capital 
resources in the process of the research and development activities according to the schedule of fund raising. The Company 
intends to explore various means of fundraising to meet its funding requirements to carry out the business operations, such as 
the  issuance  of  ADS  representing  its  ordinary  shares.  The  Company  may  also  use  other  means  of  financing  such  as  out 
licensing to generate revenue and cash. Management believes that it currently has plans and opportunities in place which will 
allow to fund and meet its operating expenses and capital expenditure requirements and meet its obligations for at least the next 
twelve  months  from  December  31,  2022.  However,  the  future  viability  of  the  Company  depends  on  its  ability  to  raise 
additional capital to finance its operations.

On February 24, 2023, the Company entered into a Unit Purchase Agreement (the “Purchase Agreement”) with fund entities 
affiliated with BVF Partners L.P. (collectively, “BVF”) private placement. The Private Placement was on February 27, 2023 
(the “Closing”), subject to customary closing conditions. The Private Placement is expected to result in gross proceeds to the 
Company of approximately $20.0  million,  and  an  additional  $80.0  million  in  gross  proceeds  to  the  Company  if  all  Tranche 
Warrants are fully-exercised. Please refer to Note 25(b).

a)

b)

On  January  31,  2023,  the  Company  held  an  Extraordinary  General  Meeting  of  shareholders.  At  the  Extraordinary  General 
Meeting, the Company’s requisite shareholders approved (i)  an ordinary resolution to increase the Company’s authorized share 
capital  from  US$5,000,000  divided  into  500,000,000  ordinary  shares  of  a  nominal  or  par  value  of  US$0.01  each  to 
US$10,000,000  divided  into  1,000,000,000  ordinary  shares  of  a  nominal  or  par  value  of  US$0.01  each,  and  (ii)  a  special 
resolution  to  replace  existing  Memorandum  and  Articles  of  Association  of  the  Company  (being  the  Tenth  Amended  and 
Restated  Memorandum  and  Articles  of  Association  of  the  Company)  with  a  new  Memorandum  and  Articles  of  Association 
(being the Eleventh Amended and Restated Memorandum and Articles of Association of the Company) under the Companies 
Act (as amended) of the Cayman Islands.

On  February  24,  2023,  the  Company  entered  into  a  Unit  Purchase  Agreement  (the  “Purchase  Agreement”)  with  fund  entities 
affiliated with BVF Partners L.P. (collectively, “BVF”) and the other purchasers named therein (the “Purchasers”), pursuant to 
which the Company agreed to sell to the Purchasers, in a private placement offering, an aggregate of (i) 112,359,550 ordinary 
shares, which includes (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase five  ordinary  shares  (represented  by 
ADSs)  at  a  purchase  price  of  $0.178  per  ordinary  share  (or  the  equivalent  of  $0.89  per  ADS)  and  $0.8895  per  Pre-Funded 
Warrant, respectively, which represented a 15% premium to the ADSs’ ten-day volume-weighted average price (“VWAP”) (the 
“Private  Placement”).  The  Private  Placement  closed  on  February  27,  2023  and  the  Company  received  gross  proceeds  of 
approximately $20.0 million.

As part of the Private Placement, the Purchasers also received two tranches of warrants exercisable in the aggregate for up to 
55,309,112 ADSs (or Pre-Funded Warrants). The first tranche of warrants is comprised (i) 50% of warrants that are exercisable 
upon  issuance  and  until  60  days  after  the  public  announcement  of  the  Company’s  topline  data  from  its  TREK-AD  Phase  2b 
clinical trial investigating eblasakimab in atopic dermatitis (the “eblasakimab announcement”) at an exercise price of $1.30 per 
ADS (the “Tranche 1A Warrants”) and (ii) 50% of warrants which can only be exercised within 60 days after the eblasakimab 
announcement  at  an  exercise  price  based  on  the  higher  of  $1.30  and  a  50%  discount  to  the  ADS  VWAP  measured  across  a 
specified  period  after  the  eblasakimab  announcement  (the  “Tranche  1B  Warrants”).  The  second  tranche  of  warrants  similarly 
comprised (i) 50% of warrants that are exercisable upon issuance until 60 days after the public announcement of topline interim 
data from the Company’s planned Phase 2 proof of concept trial investigating farudodstat (the “farudodstat announcement”) at 
an exercise price of $1.63 per ADS (the “Tranche 2A Warrants”) and (ii) 50% of warrants which can only be exercised within 60 
days  after  the  farudodstat  announcement  at  an  exercise  price  based  on  the  higher  of  $1.63  and  a  50%  discount  to  the  ADS 
VWAP measured across a specified period after the farudodstat announcement (the “Tranche 2B Warrants,” and together with 
the Tranche 1A Warrants, Tranche 1B Warrants and Tranche 2A Warrants, the “Tranche Warrants”). The Tranche Warrants have 
a term of five years and include a mandatory exercise provision, subject to the satisfaction of certain pre-specified conditions. If 
all Tranche Warrants are fully exercised, the Company would receive an additional $80.0 million in gross proceeds.

c)

On March 10, 2023, the Company announced its plan to change the ratio of the ADSs to its ordinary shares from one (1) ADS 
representing five (5) ordinary shares to one (1) ADS representing twenty-five (25) ordinary shares (the “ADS Ratio Change”). 
The effect of the ratio changes on the ADS trading price on the Nasdaq Capital Market took place at the opening of trading on 
March 13, 2023. The loss of equivalent ADS will be $2.11, $2.40 and $3.68 for the years ended December 31, 2020, 2021, and 
2022, respectively based on retrospective application of the ADS Ratio Change. Except as otherwise indicated, all information 
in the financial statements does not give retroactive effect to the ADS Ratio Change.

General

DESCRIPTION OF ORDINARY SHARES

We are an exempted company incorporated in June 2014 with limited liability under the laws of the Cayman Islands and our affairs are governed by:

•

•

•

our Articles;

the Companies Act; and

the common law of the Cayman Islands.

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
 
 
As of the filing date of our annual report, our authorized share capital is $10,000,000 divided into 1,000,000,000 ordinary shares of a nominal or par value 
of $0.01 per ordinary share.

The following are summaries of material provisions of our Articles and the Companies Act insofar as they relate to the material terms of our share capital.

Ordinary Shares

General

Ordinary Shares. All of our outstanding ordinary shares are fully paid and non-assessable, excluding those ordinary shares that have been issued to 
JPMorgan Chase Bank, N.A., as depositary, which are being held for future sales and issuances of ADSs, if any, under the Sale Agreement. Our ordinary 
shares are issued in registered form and certificates representing the ordinary shares have been issued to certain shareholders, including JPMorgan Chase 
Bank, N.A. Our shareholders who are nonresidents of the Cayman Islands may freely hold and vote their shares. 

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. In addition, our shareholders may 
declare dividends by ordinary resolution, but no dividend shall exceed the amount recommended by our directors. Our Articles provide that the directors 
may, before recommending or declaring any dividend, set aside out of the funds legally available for distribution such sums as they think proper as a 
reserve or reserves which shall be applicable for meeting contingencies or for equalizing dividends or for any other purpose to which those funds may be 
properly applied. Under the laws of the Cayman Islands, our company may pay a dividend out of any of profit, retained earnings or the credit standing in 
our company’s share premium account, provided that in no circumstances may a dividend be paid if this would result in our company being unable to pay 
its debts as they fall due in the ordinary course of business immediately following the date on which the distribution or dividend is paid. 

Voting Rights. Holders of our ordinary shares shall be entitled to one vote per ordinary share. Voting at any shareholders’ meeting is by show of hands 
unless a poll is demanded (before or on the declaration of the result of the show of hands). A poll may be demanded by the chairman of such meeting or 
any one or more shareholders present in person or by proxy at the meeting. 

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary 
shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the outstanding 
ordinary shares at a meeting. A special resolution will be required for important matters such as a change of name, making changes to our Articles or 
approving a merger. Holders of the ordinary shares may, among other things, subdivide, consolidate or increase our share capital by ordinary resolution. 

General Meetings of Shareholders. As a Cayman Islands exempted company, we are not obliged by the Companies Act or our Articles to call shareholders’ 
annual general meetings. 

Shareholders’ general meetings may be convened by a majority of our board of directors. Advance written notice of at least seven calendar days (counting 
from the date service is deemed to take place as provided in our Articles) is required for the convening of any general meeting of our shareholders. A 
quorum required for any general meeting of shareholders consists of at least one shareholder present or by proxy, representing at least a majority of our 
paid up voting share capital. 

 
 
The Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put 
any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our Articles provide general 
meetings shall also be convened on the requisition in writing of any Shareholder or Shareholders entitled to attend and vote at our general meetings holding 
at least ten percent of the paid up voting share capital deposited at the Office specifying the objects of the meeting by notice given no later than 21 days 
from the date of deposit of the requisition duly proceed to convene a general meeting to be held. 

Transfer of Ordinary Shares. Subject to the restrictions set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an 
instrument of transfer in the usual or common form or any other form approved by our board of directors. Our board of directors may determine to decline 
to register any transfer of shares for any reason. 

Liquidation. On the winding up of our company, if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the 
whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value 
of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of 
all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay the whole of the share 
capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them. 

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their 
shares in a notice served to such shareholders at least 14 days prior to the specified time and place of payment. The shares that have been called upon and 
remain unpaid are subject to forfeiture. 

Redemption, Repurchase and Surrender of Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the option 
of the holders of these shares, on such terms and in such manner as may be determined by our board of directors. We may also repurchase any of our shares 
on such terms and in such manner as have been approved by our board of directors and agreed with the relevant shareholder. Under the Companies Act, the 
redemption or repurchase of any share may be paid out of our profits, retained earnings or out of the proceeds of a new issue of shares made for the purpose 
of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if our company can, immediately 
following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act no such share may be 
redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding or (c) if the 
company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration. 

Variations of Rights of Shares. If at any time our share capital is divided into different classes (and as otherwise determined by our board of directors) the 
rights attached to any such class may, subject to any rights or restrictions for the time being attached to any class only be materially adversely varied or 
abrogated with the consent in writing of the holders of not less than two-thirds of the issued shares of the relevant class, or with the sanction of a resolution 
passed at a separate meeting of the holders of the shares of such class by a majority of two-thirds of the votes cast at such a meeting. The board of directors 
may vary the rights attaching to any class without the consent or approval of shareholders provided that the rights will not, in the determination of the board 
of directors, be materially adversely varied or abrogated by such action. 

Issuance of Additional Shares. Our Articles authorize our board of directors to issue additional ordinary shares from time to time as our board of directors 
shall determine, to the extent of available authorized but unissued shares. 

Our Articles also authorize our board of directors to establish from time to time one or more series of preferred shares with the approval of the board of 
directors and with the approval of a special resolution and to determine, with respect to any series of preference shares, the terms and rights of that series, 
including the: 

•

•

•

Order, fixed amount or fixed ratio of allocation of dividends and other distributions on preferred shares; 

Order, fixed amount or fixed ratio of allocation of the assets available for distribution on a liquidation of the Company; 

Order of or restriction on the voting rights (including declaring no voting rights whatsoever) of preferred shareholders; 

 
 
 
•

Other matters concerning rights and obligations incidental to preferred shares; and 

• Method by which the Company is authorized or compelled to redeem the preferred shares, or a statement that redemption rights shall not 

apply. 

Prior to the issuance of any preferred shares, the Articles shall be amended to set forth the rights and obligations of the preferred shares. Issuance of these 
shares may dilute the voting power of holders of ordinary shares. 

Inspection of Books and Records. Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our 
corporate records (except for the memorandum and articles of association of our company, any special resolutions passed by our company and the register 
of mortgages and charges of our company). However, we will provide our shareholders with annual audited financial statements.

Anti-Takeover Provisions. Some provisions of our Articles may discourage, delay or prevent a change of control of our company or management that 
shareholders may consider favorable, including provisions that: 

•

•

Authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and 
restrictions of such preference shares; and 

Limit the ability of shareholders to requisition and convene general meetings of shareholders. 

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our Articles for a proper purpose and for 
what they believe in good faith to be in the best interests of our company. 

Exempted Company. We are an exempted company incorporated with limited liability under the Companies Act. The Companies Act distinguishes between 
ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the 
Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an 
ordinary company except that an exempted company: 

•

•

•

Does not have to file an annual return of its shareholders with the Registrar of Companies; 

Is not required to open its register of members for inspection; 

Does not have to hold an annual general meeting; 

• May issue negotiable or bearer shares or shares with no par value; 

• May obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first 

instance); 

• May register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands; 

• May register as a limited duration company; and 

• May register as a segregated portfolio company. 

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in 
exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other limited 
circumstances in which a court may be prepared to pierce or lift the corporate veil). 

K2 Loan Agreement, Warrant and Participation Rights

In connection with that certain Loan, Guaranty, and Security Agreement, or the Loan Agreement, with K2 HealthVentures LLC, or K2HV, and certain 
parties related to K2HV, we issued a warrant to purchase ordinary shares, or the K2 Warrant, to K2 HealthVentures Equity Trust LLC. The number of 
ordinary shares exercisable under the K2 Warrant equals (i) 2.95% of the aggregate outstanding principal amount of the term loans funded to us divided by 
(ii) the warrant price of $0.5257 per share (subject to adjustment as provided therein). The K2 Warrant also includes a cashless exercise feature allowing 
the 

 
 
holder to receive shares underlying the warrant in an amount reduced by the aggregate exercise price that would have been payable upon exercise of the 
warrant for such shares. In addition, subject to compliance with applicable securities laws (including any holding period requirements), we are required to 
use commercially reasonable efforts to facilitate and take all other actions required to enable the deposit of any or all of the ordinary shares exercisable 
under the Warrant with our depositary for the issuance of ADSs. The K2 Warrant is exercisable until its expiration on July 12, 2031. The K2 Warrant also 
provides for automatic cashless exercise or assumption as a result of certain transactions involving a merger, acquisition or sale of the company, as set forth 
in the K2 Warrant.

The Loan Agreement also provides K2 HealthVentures Equity Trust LLC with the right to participate in an aggregate amount of up to $5.0 million in any 
offering of our ADSs, ordinary shares, common stock, convertible preferred stock or other equity securities (or certain other convertible instruments but 
excluding non-convertible debt securities), but excluding any at-the-market offerings or facilities, on the same terms, conditions and pricing afforded to 
others participating in such offering; provided that with respect to any public offering, we are required to use commercially reasonable efforts to provide K2
HealthVentures Equity Trust LLC with the opportunity to invest in each such offering if it is lawful to do so (or if the offering is an underwritten public 
offering pursuant to a registration statement under the Securities Act of 1933, as amended, or the Securities Act, to use commercially reasonable efforts to

Preferred Shares

Pursuant to our Articles, we may issue shares with rights which are preferential to those of ordinary shares issued by us with the approval of a majority of 
our board of directors present at a meeting attended by two-thirds or more of the total number of directors and with the approval of a special resolution. Our 
Articles must be amended by special resolution to provide for such preference shares.

Material Differences in Corporate Law

The Companies Act is modeled after the corporate legislation of the United Kingdom but does not follow recent United Kingdom statutory enactments, and 
differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the significant differences between the 
provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in Delaware and their shareholders.

Duties of Directors

   Under Delaware law, the business and affairs of a 

   As a matter of Cayman Islands law, directors of Cayman 

corporation are managed by or under the direction of its 
board of directors. In exercising their powers, directors 
are charged with a fiduciary duty of care to protect the 
interests of the corporation and a fiduciary duty of loyalty 
to act in the best interests of its shareholders. The duty of 
care requires that directors act in an informed and 
deliberative manner and inform themselves, prior to 
making a business decision, of all material information 
reasonably available to them. The duty of care also 
requires that directors exercise care in overseeing and 
investigating the conduct of the corporation’s employees. 
The duty of loyalty may be summarized as the duty to act 
in good faith, not out of self-interest, and in a manner 

Islands companies owe fiduciary duties to their respective 
companies to, amongst other things, act in good faith in 
their dealings with or on behalf of the company and 
exercise their powers and fulfill the duties of their office 
honestly. Five core duties are:

•  a duty to act in good faith in what the directors bona 
fide consider to be the best interests of the company 
(and in this regard, it should be noted that the duty is 
owed to the company and not to associate companies, 
subsidiaries or holding companies);

•  a duty not to personally profit from opportunities that 

arise from the office of 

 
 
 
 
 
 
 
 
 
  Delaware

  which the director reasonably believes to be in the best 

interests of the shareholders.

Limitations on Personal 
Liability of Directors

   Subject to the limitations described below, a certificate of 

incorporation may provide for the elimination or 
limitation of the personal liability of a director to the 
corporation or its shareholders for monetary damages for 
a breach of fiduciary duty as a director.

Such provision cannot limit liability for breach of loyalty, 
bad faith, intentional misconduct, unlawful payment of 
dividends or unlawful share purchase or redemption. In 
addition, the certificate of incorporation cannot limit 
liability for any act or omission occurring prior to the 
date when such provision becomes effective.

  Cayman Islands

director;

• a duty of trusteeship of the company’s assets;

• a duty to avoid conflicts of interest; and

• a duty to exercise powers for the purpose for which 

such powers were conferred.

A director of a Cayman Islands company also owes the 
company a duty to act with skill, care and diligence. It was 
previously considered that a director need not exhibit in 
the performance of his or her duties a greater degree of 
skill than may reasonably be expected from a person of his 
or her knowledge and experience. However, there are 
indications that the courts are moving towards an objective 
standard with regard to the required skill and care.

   The Companies Act has no equivalent provision to 
Delaware law regarding the limitation of director’s 
liability. However, as a matter of public policy, Cayman 
Islands law will not allow the limitation of a director’s 
liability to the extent that the liability is a consequence of 
the director committing a crime or of the director’s own 
fraud, dishonesty or willful default.

Indemnification of Directors, 
Officers, Agents, and Others

   A corporation has the power to indemnify any director, 
officer, employee, or agent of the corporation who was, 
is, or is threatened to be made a party who acted in good 
faith and in a manner he believed to be in the best 
interests of the corporation, and if with respect to a 
criminal proceeding, had no reasonable cause to believe 
his conduct would be unlawful, against amounts actually 
and reasonably incurred.

   Cayman Islands law does not limit the extent to which a 

company’s articles of association may provide for 
indemnification of directors and officers, except to the 
extent any such provision may be held by the Cayman 
Islands courts to be contrary to public policy, such as to 
provide indemnification against the consequences of 
committing a crime, or against the indemnified person’s 
own fraud or dishonesty.

Interested Directors

   Under Delaware law, a transaction in which a director 

   Our Articles contain a provision that allows the director 

who has an interest is not void or voidable solely because 
such interested director is present at or participates in the 
meeting that authorizes the transaction if: (i) the material 
facts as to such interested director’s relationship or 
interests are disclosed or are known to the board of 

who is in any way, whether directly or indirectly, interested 
in a contract or proposed contract with us shall declare the 
nature of his interest at a meeting of the directors. A 
general notice given to the directors by any director to the 
effect that he is to be regarded as interested in any contract 
or other arrangement which may 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  Delaware

  Cayman Islands

  directors and the board in good faith authorizes the 

transaction by the affirmative vote of a majority of the 
disinterested directors, even though the disinterested 
directors are less than a quorum, (ii) such material facts 
are disclosed or are known to the shareholders entitled to 
vote on such transaction and the transaction is 
specifically approved in good faith by vote of the 
shareholders, or (iii) the transaction is fair as to the 
corporation as of the time it is authorized, approved or 
ratified. Under Delaware law, a director could be held 
liable for any transaction in which such director derived 
an improper personal benefit.

   The certificate of incorporation may include a provision 
requiring supermajority approval by the directors or 
shareholders for any corporate action.

In addition, under Delaware law, certain business 
combinations involving interested shareholders require 
approval by a supermajority of the non-interested 
shareholders.

Voting Requirements

Voting for Directors

   Under Delaware law, unless otherwise specified in the 

certificate of incorporation or bylaws of the corporation, 
directors shall be elected by a plurality of the votes of the 
shares present in person or represented by proxy at the 
meeting and entitled to vote on the election of directors.

thereafter be made with that company or firm shall be 
deemed a sufficient declaration of interest in regard to any 
contract so made. A director may vote in respect of any 
contract or proposed contract or arrangement 
notwithstanding that he may be interested therein and if he 
does so his vote shall be counted and he may be counted in 
the quorum at any meeting of the directors at which any 
such contract or proposed contract or arrangement shall 
come before the meeting for consideration.

   For the protection of shareholders, certain matters must be 
approved by special resolution of the shareholders as a 
matter of Cayman Islands law, including alteration of the 
memorandum or articles of association, appointment of 
inspectors to examine company affairs, reduction of share 
capital (subject, in relevant circumstances, to court 
approval), change of name, authorization of a plan of 
merger or transfer by way of continuation to another 
jurisdiction or consolidation or voluntary winding up of the 
company.

The Companies Act requires that a special resolution be 
passed by a majority of at least two-thirds or such higher 
percentage as set forth in the articles of association, of 
shareholders being entitled to vote and do vote in person or 
by proxy at a general meeting, or by unanimous written 
consent of shareholders entitled to vote at a general 
meeting. Our Articles provide that a resolution in writing 
signed by all the shareholders for the time being entitled to 
receive notice of and to attend and vote at our general 
meetings (or being corporations by their duly authorized 
representatives) shall be as valid and effective as if the 
same had been passed at a general meeting duly convened 
and held.

   The Companies Act defines “special resolution” only. A 
company’s articles of association can therefore tailor the 
definition of “ordinary resolutions” as a whole, or with 
respect to specific provisions.

Our Articles contain a provision that shareholders may by 
ordinary resolution appoint any person to be a director. 
Further, the directors shall have power at any time and 
from

Cumulative Voting

   No cumulative voting for the election of directors unless 

so provided in the certificate of incorporation.

time to time to appoint any person to be a director, either 
as a result of a casual vacancy or as an additional director, 
subject to the maximum number (if any) imposed by 
Ordinary Resolution.

   No cumulative voting for the election of directors unless so 
provided in the articles of association. Our Articles do not 
expressly provide for cumulative voting on the election of 
directors.

Directors’ Powers Regarding 
Bylaws

   The certificate of incorporation may grant the directors 

   The memorandum and articles of association may only be 

the power to adopt, amend or repeal bylaws.

amended by a special resolution of the shareholders.

Nomination and Removal of 
Directors and Filling 
Vacancies on Board

Mergers and Similar 
Arrangements

Shareholders may generally nominate directors if they 
comply with advance notice provisions and other 
procedural requirements in company bylaws. Holders of a 
majority of the shares may remove a director with or 
without cause, except in certain cases involving a 
classified board or if the company uses cumulative 
voting. Unless otherwise provided for in the certificate of 
incorporation, directorship vacancies are filled by a 
majority of the directors elected or then in office.

Under Delaware law, with certain exceptions, a merger, 
consolidation, exchange or sale of all or substantially all 
the assets of a corporation must be approved by the board 
of directors and a majority of the outstanding shares 
entitled to vote thereon. Under Delaware law, a 
shareholder of a corporation participating in certain major 
corporate transactions may, under certain circumstances, 
be entitled to appraisal rights pursuant to which such 
shareholder may receive cash in the amount of the fair 
value of the shares held by such shareholder (as 
determined by a court) in lieu of the consideration such 
shareholder would otherwise receive in the transaction. 
Delaware law also provides that a parent corporation, by 
resolution of its board of directors, may merge with any 
subsidiary, of which it owns at least 90% of each class of 
capital stock without a vote by shareholders of such 
subsidiary. Upon any such merger, dissenting 
shareholders of the subsidiary would have appraisal 
rights.

Nomination and removal of directors and filling of board 
vacancies are governed by the terms of the articles of 
association. 

The Companies Act provides for the merger or 
consolidation of two or more companies into a single 
entity. The legislation makes a distinction between a 
“consolidation” and a “merger.” In a consolidation, a new 
entity is formed from the combination of each participating 
company, and the separate consolidating parties, as a 
consequence, cease to exist and are each stricken by the 
Registrar of Companies. In a merger, one company 
remains as the surviving entity, having in effect absorbed 
the other merging party (with the vesting of the 
undertaking, property and liabilities of the other merging 
party with the surviving company) that then ceases to exist.

Two or more Cayman Islands companies may merge or 
consolidate. Cayman Islands companies may also merge or 
consolidate with foreign companies provided that the laws 
of the foreign jurisdiction permit such merger or 
consolidation.

Under the Companies Act, a written plan of merger or 
consolidation shall be approved by the directors of each 
constituent company, 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
 
 
 
 
 
 
 
 
  Delaware

  Cayman Islands

  which then must be authorized by each constituent 

company by way of (i) a special resolution of the members 
of each such constituent company; and (ii) such other 
authorization, if any, as may be specified in such 
constituent company’s articles of association.

Shareholder approval is not required where a parent 
company registered in the Cayman Islands seeks to merge 
with one or more of its subsidiaries registered in the 
Cayman Islands and a copy of the plan of merger is given 
to every member of each subsidiary company to be merged 
unless that member agrees otherwise.

Secured creditors must consent to the merger although 
application can be made to the Grand Court of the Cayman 
Islands for such requirement to be waived if such secured 
creditor does not grant its consent to the merger. Where a 
foreign company wishes to merge with a Cayman 
company, consent or approval to the transfer of any 
security interest granted by the foreign company to the 
resulting Cayman entity in the transaction is required, 
unless otherwise released or waived by the secured party. 
If the merger plan is approved, it is then filed with the 
Cayman Islands Registrar of Companies along with a 
declaration by a director of each company. The Registrar 
of Companies will then issue a certificate of merger which 
shall be prima facie evidence of compliance with all 
requirements of the Companies Act in respect of the 
merger or consolidation.

Cayman companies may also be restructured or 
amalgamated under supervision of the Grand Court of the 
Cayman Islands by way of a court-sanctioned “scheme of 
arrangement.” A scheme of arrangement is one of several 
transactional mechanisms available in the Cayman Islands 
for achieving a restructuring. Others include share capital 
exchange, merger (as described above), asset acquisition or 
control, through contractual arrangements, of an operating 
business. A scheme of arrangement must not be beyond the 
powers of the company, as stated in the constitutional 
documents of the company and also requires the approval 
of a majority, in number, of each class of shareholders and 
creditors with whom the arrangement is to be made and 
who must in addition represent three-fourths in value of 
each such class of 

 
 
 
 
 
 
 
 
 
 
  Delaware

  Cayman Islands

shareholders or creditors, as the case may be, that are 
present and voting either in person or by proxy at the 
meeting summoned for that purpose. The convening of the 
meetings and subsequently the terms of the arrangement 
must be sanctioned by the Grand Court of the Cayman 
Islands. While a dissenting shareholder would have the 
right to express to the Court its view that the transaction 
ought not be approved, the Court can be expected to 
approve the scheme of arrangement if it is satisfied that:

•  the statutory provisions as to the required majority vote 

have been met;

• the classes which are required to approve the scheme of 
arrangement have been properly constituted, so that the 
members of such classes are properly and fairly 
represented and the statutory majority are acting bona 
fide without coercion of the minority to promote interests 
adverse to those of the class;

•  the meetings held by the company in relation to the 

approval of the scheme of arrangement by such classes 
have been convened and held in accordance with any 
directions given by the Court;

• the scheme of arrangement has been properly explained 
to the shareholders or creditors so that they have been 
able to exercise an informed vote in respect of the 
scheme; 

• the scheme of arrangement is one which an intelligent 
and honest man, who is a member of the relevant class 
and properly acting might approve.

When a takeover offer is made and accepted by holders of 
90% of the shares within four months, the offeror may, 
within a two-month period, require the holders of the 
remaining shares to transfer such shares on the terms of the 
offer. An objection may be made to the Grand Court of the 
Cayman Islands but is unlikely to succeed unless there is 
evidence of fraud, bad faith or collusion. If the 
arrangement and reconstruction are thus approved, any 
dissenting shareholders would have no rights comparable 
to appraisal rights, which would otherwise ordinarily be 
available to dissenting shareholders of United States 
corporations, providing rights to receive payment in cash 
for the judicially determined value of the shares.

Shareholder Suits

   Class actions and derivative actions generally are 

available to shareholders under Delaware law for, among 
other things, breach of fiduciary duty, corporate waste 
and actions not taken in accordance with applicable law. 
In such actions, the court generally has discretion to 
permit the winning party to recover attorneys’ fees 
incurred in connection with such action.

   The rights of shareholders under Cayman Islands law are 
not as extensive as those under Delaware law. Class 
actions are generally not available to shareholders under 
Cayman Islands laws; historically, there have not been any 
reported instances of such class actions having been 
successfully brought before the Cayman Islands courts. In 
principle, we will normally be the proper plaintiff in any 
claim based on a breach of duty owed to the Company, and 
a claim against (for example) the Company’s officers or 
directors usually may not be brought by a shareholder. A 
derivative action may be brought by a minority shareholder 
in only limited circumstances. In this regard, the Cayman 
Islands courts would ordinarily be expected to follow 
English case law precedent, which would permit a 
shareholder to commence an action in the company’s name 
to remedy a wrong done to the company where the act 
complained of cannot be ratified by the shareholders and 
where control of the company by the wrongdoer results in 
the company not pursuing a remedy itself. The case law 
shows that derivative actions have been permitted in 
respect of acts that are beyond the company’s corporate 
power, illegal, where the individual rights of the plaintiff 
shareholder have been infringed or are about to be 
infringed and acts that are alleged to constitute a “fraud on 
the minority.”

Inspection of Corporate 
Records

   Under Delaware law, shareholders of a Delaware 

corporation have the right during normal business hours 
to inspect for any proper purpose, and to obtain copies of 
list(s) of shareholders and other books and records of the 
corporation and its subsidiaries, if any, to the extent the 
books and records of such subsidiaries are available to the 
corporation.

   Except in respect of the inspection of a Company's 
Register of Directors upon payment of a fee at the 
Registrar of Companies in the Cayman Islands by any 
person, shareholders of a Cayman Islands exempted 
company have no general right under Cayman Islands law 
to inspect or obtain copies of a list of shareholders or other 
corporate records (other than the register of mortgages or 
charges) of the company. However, these rights may be 
provided in the company’s articles of association.

Shareholder Proposals

   Unless provided in the corporation’s certificate of 

incorporation or bylaws, Delaware law does not include a 
provision restricting the manner in which shareholders 
may bring business before a meeting.

   The Companies Act does not provide shareholders any 
right to bring business before a meeting or requisition a 
general meeting. However, these rights may be provided in 
the company’s articles of association. Our Articles do 
provide for these rights.

Approval of Corporate 
Matters by Written Consent

   Delaware law permits shareholders to take action by 
written consent signed by the holders of outstanding 
shares having not less than the minimum number of votes 
that would be necessary to authorize or take such action 
at a meeting of shareholders.

   The Companies Act allows a special resolution to be 

passed in writing if signed by all the voting shareholders 
(if authorized by the articles of association).

Our Articles authorize such written consents.

Calling of Special 
Shareholders Meetings

   Delaware law permits the board of directors or any 

person who is authorized under a corporation’s certificate 
of incorporation or bylaws to call a special meeting of 
shareholders.

   The Companies Act does not have provisions governing 
the proceedings of shareholders meetings which are 
usually provided in the articles of association.

Our Articles allow for shareholders’ meetings to be 
convened on the requisition in writing of any shareholder 
or shareholders holding at least ten percent of the paid up 
voting share capital. Our Articles also provide that, in the 
event that our board of directors does not or cannot 
convene a general meeting upon the duly delivered 
requisition of any shareholder or shareholders (as 
described above), the requisitionists themselves may 
convene the general meeting in the same manner, as nearly 
as possible, as that in which general meetings may be 
convened by the Directors, and all reasonable expenses 
incurred by the requisitionists as a result of the failure of 
the Directors to convene the general meeting shall be 
reimbursed to them by us.

 
 
 
 
 
 
 
 
DESCRIPTION OF AMERICAN DEPOSITARY SHARES

JPMorgan Chase Bank, N.A., or JPMorgan, as depositary will issue the ADSs in connection with an offering. Each ADS will represent an ownership 
interest in a designated number of our ordinary shares which we will deposit with the depositary or the custodian, as agent of the depositary, under the 
deposit agreement among ourselves, the depositary and yourself as an ADR holder. In the future, each ADS will also represent any securities, cash or other 
property deposited with the depositary but which have not distributed directly to you. Unless certificated ADRs are specifically requested by you, all ADSs 
will be issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in 
such ADSs. In our description, references to ADRs shall include the statements you will receive which reflect your ownership of ADSs. 

The depositary’s office is located at 383 Madison Avenue, Floor 11, New York, NY, 10179. 

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered 
in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through 
your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADR holder 
described in this section. You should consult with your broker or financial institution to find out what those procedures are. 

As an ADR holder, we will not treat you as a shareholder of ours and you will not have any direct shareholder rights. Because the depositary or its nominee 
will be the shareholder of record for the ordinary shares represented by all outstanding ADSs, shareholder rights rest with such record holder. Your rights 
are those of an ADR holder. Such rights derive from the terms of the deposit agreement to be entered into among us, the depositary and all holders from 
time to time of ADRs issued under the deposit agreement. The obligations of the depositary and its agents are also set out in the deposit agreement. 
Because the depositary or its nominee will actually be the registered owner of the ordinary shares, you must rely on it to exercise the rights of a shareholder 
on your behalf. The deposit agreement and the ADSs are governed by New York law. However, our obligations to the holders of ordinary shares will 
continue to be governed by the Cayman Islands, which may be different from the laws of the United States. Under the deposit agreement, as an ADR 
holder, you agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement, the 
ADSs, the ADRs or the transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and you irrevocably 
waive any objection which you may have to the laying of venue of any such proceeding and irrevocably submit to the exclusive jurisdiction of such courts 
in any such suit, action or proceeding. 

The following is a summary of what we believe to be the material terms of the deposit agreement. Notwithstanding this, because it is a summary, it may not 
contain all the information that you may otherwise deem important. For more complete information, you should read the entire deposit agreement and the 
form of ADR which contains the terms of your ADSs. 

Share Dividends and Other Distributions 

How will I receive dividends and other distributions on the ordinary shares underlying my ADSs? We may make various types of distributions with 
respect to our securities. The depositary has agreed that, to the extent practicable, it will distribute to you the cash dividends or other distributions it or the 
custodian receives on ordinary shares or other deposited securities, after converting any cash received into U.S. dollars (if it determines such conversion 
may be made on a reasonable basis) and, in all cases, making any necessary deductions provided for in the deposit agreement. The depositary may utilize a 
division, branch or affiliate of JPMorgan to direct, manage and/or execute any public and/or private sale of securities under the deposit agreement. Such 
division, branch and/or affiliate may charge the depositary a fee in connection with such sales, which fee is considered an expense of the depositary. You 
will receive these distributions in proportion to the number of underlying securities that your ADSs represent. 

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner: 

•

Cash. The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or other cash distribution or the net 
proceeds of sales of any other distribution or portion thereof (to the extent applicable), on an averaged or other practicable basis, subject to 
(i) appropriate adjustments for taxes withheld, (ii) such distribution being impermissible or impracticable with respect to certain registered 
ADR holders, and (iii) 

 
 
deduction of the depositary’s and/or its agents’ fees and expenses in (1) converting any foreign currency to U.S. dollars to the extent that it 
determines that such conversion may be made on a reasonable basis, (2) transferring foreign currency or U.S. dollars to the United States by 
such means as the depositary may determine to the extent that it determines that such transfer may be made on a reasonable basis, (3) 
obtaining any approval or license of any governmental authority required for such conversion or transfer, which is obtainable at a 
reasonable cost and within a reasonable time and (4) making any sale by public or private means in any commercially reasonable manner. If 
exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may lose some or all of the value of the 
distribution. 

Shares. In the case of a dividend or free distribution in ordinary shares, the depositary will issue additional ADRs to evidence the number of 
ADSs representing such ordinary shares. Only whole ADSs will be issued. Any ordinary shares which would result in fractional ADSs will 
be sold and the net proceeds will be distributed in the same manner as cash to the ADR holders entitled thereto. 

Rights to receive additional ordinary shares. In the case of a distribution of rights to subscribe for additional ordinary shares or other rights, 
if we timely provide evidence satisfactory to the depositary that it may lawfully distribute such rights, the depositary will distribute warrants 
or other instruments in the discretion of the depositary representing such rights. However, if we do not timely furnish such evidence, the 
depositary may: 

•

•

(i)

Sell such rights if practicable and distribute the net proceeds in the same manner as cash to the ADR holders entitled thereto; or 

(ii)

(If it is not practicable to sell such rights by reason of the non-transferability of the rights, limited markets therefor, their short 
duration or otherwise, do nothing, in which case ADR holders will receive nothing and the rights may lapse. 

Other Distributions. In the case of a distribution of securities or property other than those described above, the depositary may either (i) distribute such 
securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution of such securities or property 
not to be equitable and practicable, sell such securities or property and distribute any net proceeds in the same way it distributes cash. 

If the depositary determines in its discretion that any distribution described above is not practicable with respect to any specific registered ADR holder, the 
depositary may choose any method of distribution that it deems practicable, including the distribution of foreign currency, securities or property, or it may 
retain such items, without liability for interest thereon or investment thereof, on behalf of the ADR holder as deposited securities, in which case the ADSs 
will also represent the retained items. 

 Any U.S. dollars will be distributed by checks drawn on a bank in the United States for whole dollars and cents. Fractional cents will be withheld without 
liability and dealt with by the depositary in accordance with its then current practices. 

The depositary is not responsible if it fails to determine that any distribution or action is lawful or reasonably practicable. 

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, shares or other 
securities at a specified price, nor that any of such transactions can be completed within a specified time period. All purchases and sales of securities will 
be handled by the depositary in accordance with its then current policies, which are currently set forth in the “Depositary Receipt Sale and Purchase of 
Security” section of https://www.adr.com/Investors/FindOutAboutDRs, the location and contents of which are not incorporated into this exhibit and which 
the depositary shall be solely responsible for. 

Deposit, Withdrawal and Cancellation 

How does the depositary issue ADSs? Subject to any restrictions on deposit provided for under the laws of the Cayman Islands and the deposit agreement, 
the depositary will issue ADSs against the deposit of: (i) ordinary shares in registered form, validly issued and outstanding; (ii) rights to receive ordinary 
shares from us or any registrar, transfer agent, clearing agent or other entity recording share ownership or transactions, subject in each case to payment of 
the fees and expenses owing to the depositary in connection with such issuance. 

 
 
Ordinary shares deposited in the future with the custodian must be accompanied by certain documents, including Share certificates, and a certified share 
extract, reflecting the registration of the shares in the name of JPMorgan, as depositary for the benefit of holders of ADRs or in such other name as the 
depositary shall direct, a delivery order directing the depositary to issue ADSs to, or upon the written order of, the person designated in such order, 
instruments assigning to the custodian, the depositary or the nominee of either of them any distribution on the ordinary shares so deposited or indemnity 
therefor, and proxies entitling the custodian to vote the deposited ordinary shares. 

The custodian will hold all deposited ordinary shares for the account and to the order of the depositary for the benefit of holders of ADRs. ADR holders 
thus have no direct ownership interest in the ordinary shares and only have such rights as are contained in the deposit agreement. The custodian will also 
hold any additional securities, property and cash received on or in substitution for the deposited ordinary shares. The deposited ordinary shares and any 
such additional items are referred to as “deposited securities.” 

Upon each deposit of ordinary shares, receipt of related delivery documentation and compliance with the other provisions of the deposit agreement, 
including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in 
the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, 
unless specifically requested to the contrary, be part of the depositary’s direct registration system, and a registered holder will receive periodic statements 
from the depositary which will show the number of ADSs registered in such holder’s name. An ADR holder can request that the ADSs not be held through 
the depositary’s direct registration system and that a certificated ADR be issued. 

How do ADR holders cancel an ADS and obtain deposited securities? In accordance with the deposit agreement and subject to the requirements of the 
laws of the Cayman Islands, an ADR holder may request the depositary to withdraw from the depositary receipt facility created by the deposit agreement 
the ordinary shares represented by such holder’s ADRs and transfer such ordinary shares to such holder or, upon the written order of any person designated 
in such ADR holder’s written order, upon surrender of (a) a certificated ADR in a form satisfactory to the depositary or (b) proper instructions and 
documentation in the case of an ADR issued through the depositary’s direct registration system, as the case may be, then an ADR holder hereof is entitled 
to delivery at, or to the extent in dematerialized form from, the custodian’s office of the deposited securities at the time represented by the ADSs evidenced 
by this ADR. At the request, risk and expense of the holder hereof, the depositary may deliver such deposited securities at such other place as may have 
been requested by the holder. 

The depositary may only restrict the withdrawal of deposited securities in connection with: 

temporary delays caused by closing our transfer books or those of the depositary or the deposit of ordinary shares in connection with voting 
at a shareholders’ meeting, or the payment of dividends; 

the payment of fees, taxes and similar charges; or 

compliance with any U.S. or foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited securities.

Record Dates 

The depositary may, after consultation with us if practicable, fix record dates (which, to the extent applicable, shall be as near as practicable to any 
corresponding record dates set by us) for the determination of the registered ADR holders who will be entitled (or obligated, as the case may be): 

•

•

•

•

to receive any distribution on or in respect of deposited securities, 

to give instructions for the exercise of voting rights, 

to pay the fee assessed by the depositary for administration of the ADR program and for any expenses as provided for in the deposit 
agreement, or 

to receive any notice or to act or be obligated in respect of other matters, 

all subject to the provisions of the deposit agreement. 

 
 
Voting Rights 

How do I vote? If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to 
exercise the voting rights for the shares which underlie your ADSs. As soon as practicable after receipt from us of notice of any meeting at which the 
holders of shares are entitled to vote, or of our solicitation of consents or proxies from holders of shares, the depositary shall fix the ADS record date in 
accordance with the provisions of the deposit agreement. The depositary shall, if we request in writing in a timely manner at least 30 days prior to the date 
of such vote or meeting and at our expense and provided no legal prohibitions exist, distribute to the registered ADR holders a notice stating final 
information particular to the voting materials received by the depositary and describing how you may instruct, or, subject to the next paragraph, will be 
deemed to instruct, the depositary to exercise the voting rights for the shares which underlie your ADSs, including instructions for giving a discretionary 
proxy to a person designated by us. Each ADR holder shall be solely responsible for the forwarding of voting notices to the beneficial owners of ADSs 
registered in such holder’s name. In accordance with our memorandum and articles of association, a shareholder may not exercise its own vote or by proxy 
on behalf of another shareholder of the company in respect of any contract or proposed contract or arrangement if such shareholder may be interested 
therein. Accordingly, no ADR holder shall instruct the depositary to vote on its behalf on any matter to be considered at the relevant meeting in respect of 
which such holder is interested. 

 To the extent we have provided the depositary with at least 35 days’ notice of a proposed meeting, the notice will be received by all ADR holders and 
beneficial owners no less than 10 days prior to the date of the meeting and/or the cut-off date for the solicitation of consents, and the depositary does not 
receive instructions on a particular agenda item from a ADR holder (including, without limitation, any entity or entities acting on behalf of the nominee for 
The Depository Trust Company) in a timely manner, such holder shall be deemed, and in the deposit agreement the depositary is instructed to deem such 
holder, to have instructed the depositary to give a discretionary proxy for such agenda item(s) to a person designated by us to vote the shares represented by 
their ADSs for which actual instructions were not so given by all such ADR holders on such agenda item(s), provided that no such instruction shall be 
deemed given and no discretionary proxy shall be given unless (1) we inform the depositary in writing that (a) we wish such proxy to be given with respect 
to such agenda item(s), (b) there is no substantial opposition existing with respect to such agenda item(s) and (c) such agenda item(s), if approved, would 
not materially or adversely affect the rights of holders of shares and (2) we have provided the depositary with an opinion of our counsel, in form and 
substance satisfactory to the depositary, confirming that (a) the granting of such discretionary proxy does not subject the depositary to any reporting 
obligations in the Cayman Islands, (b) the granting of such proxy will not result in a violation of Cayman Island laws, rules, regulations or permits, (c) the 
voting arrangement and deemed instruction as contemplated herein will be given effect under Cayman Islands laws, rules and regulations, and (d) the 
granting of such discretionary proxy will not under any circumstances result in the ADSs being treated as assets of the depositary under Cayman Island 
laws, rules or regulations. 

Holders are strongly encouraged to forward their voting instructions to the depositary as soon as possible. For instructions to be valid, the ADR department 
of the depositary that is responsible for proxies and voting must receive them in the manner and on or before the time specified, notwithstanding that such 
instructions may have been physically received by the depositary prior to such time. The depositary will not itself exercise any voting discretion. 
Furthermore, neither the depositary nor its agents are responsible for any failure to carry out any voting instructions, for the manner in which any vote is 
cast or for the effect of any vote. Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may, to the extent not prohibited 
by law or regulations, or by the requirements of the stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the 
depositary in connection with any meeting of, or solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders 
of ADRs a notice that provides such holders with, or otherwise publicizes to such holders, instructions on how to retrieve such materials or receive such 
materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials). 

There is no guarantee that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their 
ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. 

We have advised the depositary that under the Cayman Islands law and our memorandum and articles of association, voting at any meeting of our 
shareholders is by show of hands unless a poll is (before or on the declaration of the results of the show of hands) demanded. In the event that voting on 
any resolution or matter is conducted on a show of hands basis in accordance with the memorandum and articles of association, the depositary will refrain 
from voting and the voting instructions received 

 
 
by the depositary from holders shall lapse. The depositary will not demand a poll or join in demanding a poll, whether or not requested to do so by holders 
of ADSs. 

Reports and Other Communications 

Will ADR holders be able to view our reports? The depositary will make available for inspection by ADR holders at the offices of the depositary and the 
custodian, or upon request made to the depositary (which request may be refused by the depositary at its discretion), the deposit agreement, the provisions 
of or governing deposited securities, and any written communications from us which are both received by the custodian or its nominee as a holder of 
deposited securities and made generally available to the holders of deposited securities. 

 Additionally, if we make any written communications generally available to holders of our ordinary shares, and we furnish copies thereof (or English 
translations or summaries) to the depositary, it will distribute the same to registered ADR holders. 

Fees and Expenses 

What fees and expenses will I be responsible for paying? The depositary may charge each person to whom ADSs are issued, including, without limitation, 
issuances against deposits of ordinary shares, issuances in respect of share distributions, rights and other distributions, issuances pursuant to a stock 
dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or 
deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADRs are cancelled or reduced for any other 
reason, $5.00 for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The depositary may sell 
(by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distributions prior to such deposit 
to pay such charge. 

The following additional charges shall be incurred by the ADR holders, by any party depositing or withdrawing shares or by any party surrendering ADSs 
and/or to whom ADSs are issued (including, without limitation, issuances pursuant to a stock dividend or stock split declared by us or an exchange of stock 
regarding the ADSs or the deposited securities or a distribution of ADSs), whichever is applicable: 

•

•

•

•

•

•

a fee of up to $0.05 per ADS upon which any cash distribution made pursuant to the deposit agreement; 

an aggregate fee of $0.05 or less per ADS per calendar year (or portion thereof) for services performed by the depositary in administering 
the ADRs (which fee may be charged on a periodic basis during each calendar year and shall be assessed against holders of ADRs as of the 
record date or record dates set by the depositary during each calendar year and shall be payable in the manner described in the next 
succeeding provision); 

a fee for the reimbursement of such fees, charges and expenses as are incurred by the depositary and/or any of its agents (including, without 
limitation, the custodian and expenses incurred on behalf of ADR holders in connection with compliance with foreign exchange control 
regulations or any law or regulation relating to foreign investment) in connection with the servicing of the ordinary shares or other 
deposited securities, the sale of securities (including, without limitation, deposited securities), the delivery of deposited securities or 
otherwise in connection with the depositary’s or its custodian’s compliance with applicable law, rule or regulation (which fees and charges 
shall be assessed on a proportionate basis against ADR holders as of the record date or dates set by the depositary and shall be payable at 
the sole discretion of the depositary by billing such ADR holders or by deducting such charge from one or more cash dividends or other 
cash distributions); 

a fee for the distribution of securities (or the sale of securities in connection with a distribution), such fee being in an amount equal to the 
$0.05 per ADS issuance fee for the execution and delivery of ADSs which would have been charged as a result of the deposit of such 
securities (treating all such securities as if they were ordinary shares) but which securities or the net cash proceeds from the sale thereof are 
instead distributed by the depositary to those ADR holders entitled thereto; 

stock transfer or other taxes and other governmental charges; 

SWIFT, cable, telex and facsimile transmission and delivery charges incurred at your request in connection with the deposit or delivery of 
shares, ADRs or deposited securities; 

 
 
•

•

transfer or registration fees for the registration or transfer of deposited securities on any applicable register in connection with the deposit or 
withdrawal of deposited securities; and

fees of any division, branch or affiliate of JPMorgan utilized to direct, manage and/or execute any public and/or private sale of securities 
under the deposit agreement. 

Foreign Exchange Related Matters. To facilitate the administration of various depositary receipt transactions, including disbursement of dividends or other 
cash distributions and other corporate actions, the depositary may engage the foreign exchange desk within JPMorgan and/or its affiliates in order to enter 
into spot foreign exchange transactions to convert foreign currency into U.S. dollars, or FX Transactions. For certain currencies, FX Transactions are 
entered into with JPMorgan or an affiliate, as the case may be, acting in a principal capacity. For other currencies, FX Transactions are routed directly to 
and managed by an unaffiliated local custodian (or other third party local liquidity provider), and neither the JPMorgan nor any of its affiliates is a party to 
such FX Transactions. 

The foreign exchange rate applied to an FX Transaction will be either (a) a published benchmark rate, or (b) a rate determined by a third party local 
liquidity provider, in each case plus or minus a spread, as applicable. The depositary will disclose which foreign exchange rate and spread, if any, apply to 
such currency on the “Disclosure” page (or successor page) of www.adr.com. Such applicable foreign exchange rate and spread may (and neither the 
depositary, JPMorgan nor any of their affiliates is under any obligation to ensure that such rate does not) differ from rates and spreads at which comparable 
transactions are entered into with other customers or the range of foreign exchange rates and spreads at which JPMorgan or any of its affiliates enters into 
foreign exchange transactions in the relevant currency pair on the date of the FX Transaction. Additionally, the timing of execution of an FX Transaction 
varies according to local market dynamics, which may include regulatory requirements, market hours and liquidity in the foreign exchange market or other 
factors. Furthermore, JPMorgan and its affiliates may manage the associated risks of their position in the market in a manner they deem appropriate without 
regard to the impact of such activities on us, the depositary, holders or beneficial owners. The spread applied does not reflect any gains or losses that may 
be earned or incurred by JPMorgan and its affiliates as a result of risk management or other hedging related activity. 

Notwithstanding the foregoing, to the extent we provide U.S. dollars to the depositary, neither JPMorgan nor any of its affiliates will execute an FX 
Transaction as set forth herein. In such case, the depositary will distribute the U.S. dollars received from us. 

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements from time to 
time between us and the depositary. The charges described above may be amended from time to time by agreement between us and the depositary. The 
right of the depositary to receive payment of fees, charges and expenses as provided above shall survive the termination of the deposit agreement. 

The depositary anticipates reimbursing us for certain expenses incurred by us that are related to the establishment and maintenance of the ADR program 
upon such terms and conditions as we and the depositary may agree from time to time. The depositary may make available to us a set amount or a portion 
of the depositary fees charged in respect of the ADR program or otherwise upon such terms and conditions as we and the depositary may agree from time 
to time. The depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing shares or surrendering ADSs for the 
purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees 
from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary 
services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for 
them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment 
owing is not timely received by the depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and 
expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees and charges owing under the deposit agreement are 
due in advance and/or when declared owing by the depositary. 

Payment of Taxes 

If any taxes or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the custodian or the depositary 
with respect to any ADR, any deposited securities represented by the ADSs evidenced thereby 

 
 
or any distribution thereon, such tax or other governmental charge shall be paid by the ADR holders to the depositary and by holding or having held an 
ADR or any ADSs evidenced thereby, the holder and all beneficial owners thereof and all prior holders and beneficial owners holders thereof, jointly and 
severally, agree to indemnify, defend and save harmless each of the depositary and its agents in respect of such tax or other governmental charge. Each 
Holder of this ADR and beneficial owner of the ADSs evidenced thereby, and each prior holder and beneficial owner and thereof, or collectively, the Tax 
Indemnitors, by holding or having held an ADR or an interest in ADSs, acknowledges and agrees that the depositary shall have the right to seek payment of 
amounts owing with respect to this ADR from any one or more Tax Indemnitor(s) as determined by the depositary in its sole discretion, without any 
obligation to seek payment from any other Tax Indemnitor(s). If an ADR holder owes any tax or other governmental charge, the depositary may (i) deduct 
the amount thereof from any distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of 
such sale. In either case the ADR holder remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to 
effect any registration, registration of transfer, split-up or combination of ADRs or withdrawal of deposited securities until such payment is made. If any tax
or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash 
distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) in such amounts and in such 
manner as the depositary deems necessary and practicable to pay such taxes and shall distribute any remaining net proceeds or the balance of any such 
property after deduction of such taxes to the ADR holders entitled thereto. 

Notwithstanding the above, we will pay all stamp duties and other similar duties or taxes payable in the Cayman Islands, Singapore, the United States of 
America and any other jurisdiction, on or in connection with the constitution and issue of the ADSs and the execution or other event concerning the deposit 
agreement. If any legal proceedings are taken to enforce our obligations under the deposit agreement or the ADSs and for the purpose of such proceedings 
any of them are required to be taken into or enforced in any jurisdiction and stamp duties or other similar duties or taxes become payable in connection 
with such proceedings in such jurisdiction, the ADR holders will pay (or reimburse the person making a valid payment of) all such stamp duties and other 
similar duties and taxes, including any penalties and interest, unless otherwise ordered by a court of competent jurisdiction in such proceedings. The 
depositary may sell any deposited securities and cancel ADSs with respect thereof in order to pay any such stamp duties or other similar duties or taxes 
owed under the deposit agreement by ADR holders without the depositary being required to request payment thereof from the ADR holders. 

Each holder and beneficial owner agrees to indemnify us, the depositary, its custodian and any of our or their respective officers, directors, employees, 
agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, 
penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained, and such obligations of the 
holders and beneficial owners shall survive the transfer of ADSs, any surrender of ADSs and withdrawal of deposited securities and any termination of the 
deposit agreement. 

Reclassifications, Recapitalizations and Mergers 

If we take certain actions that affect the deposited securities, including (i) any change in par value, split-up, consolidation, cancellation or other 
reclassification of deposited securities or (ii) any distributions of ordinary shares or other property not made to holders of ADRs or (iii) any 
recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all of our assets, then the 
depositary may choose to, and shall if reasonably requested by us: 

(1)

amend the form of ADR; 

(2) distribute additional or amended ADRs; 

(3) distribute cash, securities or other property it has received in connection with such actions; 

(4)

sell by public or private sale any securities or property received; or 

(5) none of the above. 

 
 
If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the deposited 
securities and each ADS will then represent a proportionate interest in such property. 

Amendment and Termination 

How may the deposit agreement be amended? 

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders or beneficial owners 
must be given at least 30 days’ notice of any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other 
governmental charges, transfer or registration fees, SWIFT, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or that 
otherwise prejudices any substantial existing right of ADR holders or beneficial owners. Such notice need not describe in detail the specific amendments 
effectuated thereby, but must identify to ADR holders a means to access the text of such amendment. If an ADR holder continues to hold an ADR or ADRs 
after being so notified, such ADR holder is deemed to agree to such amendment and to be bound by the deposit agreement as so amended. Any 
amendments or supplements which (i) are reasonably necessary (as agreed by us and the depositary) in order for (a) the ADSs to be registered on Form F-6 
under the Securities Act or (b) the ADSs or shares to be traded solely in electronic book-entry form and (ii) do not in either such case impose or increase 
any fees or charges to be borne by ADR holders, shall be deemed not to prejudice any substantial rights of ADR holders or beneficial owners. 
Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations which would require amendment 
or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit 
agreement and the ADR at any time in accordance with such changed laws, rules or regulations. Such amendment or supplement may take effect before a 
notice is given or within any other period of time as required for compliance. No amendment, however, will impair your right to surrender your ADSs and 
receive the underlying securities, except in order to comply with mandatory provisions of applicable law. 

How may the deposit agreement be terminated? 

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination the registered 
holders of ADRs at least 30 days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (i) resigned as 
depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders unless a successor 
depositary shall not be operating under the deposit agreement within 60 days of the date of such resignation, and (ii) been removed as depositary under the 
deposit agreement, notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not 
be operating under the deposit agreement on the 60th day after our notice of removal was first provided to the depositary. Notwithstanding anything to the 
contrary in the deposit agreement without notice to us, the depositary may terminate the deposit agreement without notice to us, but subject to giving 30 
days’ notice to the ADR holders, if: (i) we become bankrupt or insolvent, (ii) we effect (or will effect) a redemption of all or substantially all of the 
deposited securities, or a cash or share distribution representing a return of all or substantially all of the value of the deposited securities, or (iii) there 
occurs a merger, consolidation, sale of assets or other transaction as a result of which securities or other property are delivered in exchange for or in lieu of 
deposited securities. 

After termination, the depositary shall use its reasonable efforts to ensure that the ADSs cease to be DTC eligible so that neither DTC nor any of its 
nominees shall thereafter be a holder. At such time as the ADSs cease to be DTC eligible and/or neither DTC nor any of its nominees is a holder, the 
depositary shall (a) instruct its custodian to deliver all deposited securities to us along with a general stock power that refers to the names set forth on the 
ADR Register and (b) provide us with a copy of the ADR Register. Upon receipt of such deposited securities and the ADR Register, we shall use our best 
efforts to issue to each holder a share certificate representing the shares represented by the ADSs reflected on the ADR Register in such holder’s name and 
to deliver such share certificate to the holder at the address set forth on the ADR Register. After providing such instruction to the custodian and delivering a 
copy of the ADR Register to us, the depositary and its agents shall have no further obligations. 

Limitations on Obligations and Liability to ADR holders 

Limits on our obligations and the obligations of the depositary; limits on liability to ADR holders and holders of ADSs.   Prior to the issue, registration, 
registration of transfer, split-up, combination, or withdrawal of any ADRs, or the delivery of 

 
 
any distribution in respect thereof, and from time to time in the case of the production of proofs as described below, we or the depositary or its custodian 
may require: 

•

•

•

payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in 
effect for the registration of transfers of ordinary shares or other deposited securities upon any applicable register and (iii) any applicable 
fees and expenses described in the deposit agreement; 

the production of proof satisfactory to it of (i) the identity of any signatory and genuineness of any signature and (ii) such other information, 
including without limitation, information as to citizenship, residence, exchange control approval, beneficial ownership of any securities, 
compliance with applicable law, regulations, provisions of or governing deposited securities and terms of the deposit agreement and the 
ADRs, as it may deem necessary or proper; and 

compliance with such regulations as the depositary may establish consistent with the deposit agreement. 

The issuance of ADRs, the acceptance of deposits of ordinary shares, the registration, registration of transfer, split-up or combination of ADRs or the 
withdrawal of shares, may be suspended, generally or in particular instances, when the ADR register or any register for deposited securities is closed or 
when any such action is deemed advisable by the depositary; provided that the ability to withdraw shares may only be limited under the following 
circumstances: (i) temporary delays caused by closing transfer books of the depositary or our transfer books or the deposit of ordinary shares in connection 
with voting at a shareholders’ meeting, or the payment of dividends, (ii) the payment of fees, taxes, and similar charges, and (iii) compliance with any laws 
or governmental regulations relating to ADRs or to the withdrawal of deposited securities. 

The deposit agreement expressly limits the obligations and liability of the depositary, ourselves and our respective directors, officers, employees, agents 
and affiliates, provided, however, that no disclaimer of liability under the Securities Act is intended by any of the limitations of liabilities provisions of the 
deposit agreement. In the deposit agreement it provides that neither we nor the depositary nor any such other party will be liable to holders or beneficial 
owners if: 

•

•

•

•

any present or future law, rule, regulation, fiat, order or decree of the United States, the Cayman Islands, Singapore or any other country or 
jurisdiction, or of any governmental or regulatory authority or securities exchange or market or automated quotation system, the provisions 
of or governing any deposited securities, any present or future provision of our charter, any act of God, war, terrorism, nationalization, 
expropriation, currency restrictions, work stoppage, strike, civil unrest, revolutions, rebellions, explosions, computer failure or circumstance 
beyond our, the depositary’s or any such other party’s direct and immediate control shall prevent or delay, or shall cause any of them to be 
subject to any civil or criminal penalty in connection with, any act which the deposit agreement or the ADRs provide shall be done or 
performed by us, the depositary or such other party (including, without limitation, voting); 

by reason of any non-performance or delay, caused in the performance of any act or things which by the terms of the deposit agreement it is 
provided shall or may be done or performed or it exercises or fails to exercise discretion under the deposit agreement or the ADRs 
including, without limitation, any failure to determine that any distribution or action may be lawful or reasonably practicable; 

it performs its obligations under the deposit agreement and ADRs without gross negligence or willful misconduct and the depositary shall 
not be a fiduciary or have any fiduciary duty to holders or beneficial owners; or 

iIt takes any action or refrains from taking any action in reliance upon the advice of or information from legal counsel, accountants, any 
person presenting ordinary shares for deposit, any registered holder of ADRs, or any other person believed by it to be competent to give 
such advice or information, or in the case of the depositary only, from us. 

We and the depositary and its agents may rely and shall be protected in acting upon any written notice, request, direction, instruction or document believed 
by it to be genuine and to have been signed, presented or given by the proper party or parties. 

Neither we, the depositary nor our respective agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of 
any deposited securities or the ADRs which in its opinion may involve it in expense or 

 
 
liability, if indemnity satisfactory to it against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be 
required. The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection 
with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such 
information is requested or required by or pursuant to any lawful authority, including without limitation laws, rules, regulations, administrative or judicial 
process, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions made by, or the insolvency of, any securities 
depository, clearing agency or settlement system. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or 
arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan. Notwithstanding anything to the contrary contained in the 
deposit agreement or any ADRs, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, any act or 
omission to act on the part of the custodian except to the extent that any holder has incurred liability directly as a result of the custodian having (i) 
committed fraud or willful misconduct in the provision of custodial services to the depositary or (ii) failed to use reasonable care in the provision of 
custodial services to the depositary as determined in accordance with the standards prevailing in the jurisdiction in which the custodian is located. The 
depositary shall not have any liability for the price received in connection with any sale of securities, the timing thereof or any delay in action or omission 
to act nor shall it be responsible for any error or delay in action, omission to act, default or negligence on the part of the party so retained in connection with
any such sale or proposed sale. 

The depositary has no obligation to inform ADR holders or other holders of an interest in any ADSs about the requirements of the laws, rules or regulations 
of any country or jurisdiction or of any governmental or regulatory authority or any securities exchange or market or automated quotation system, or any 
changes therein or thereto. 

Additionally, none of us, the depositary or the custodian shall be liable for the failure by any registered holder or beneficial owner of ADRs to obtain the 
benefits of credits or refunds of non-U.S. tax paid against such holder’s or beneficial owner’s income tax liability. Neither we nor the depositary shall incur 
any liability for any tax or tax consequences that may be incurred by registered holders or beneficial owners on account of their ownership of ADRs or 
ADSs. 

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner 
in which any such vote is cast or for the effect of any such vote. The depositary may rely upon instructions from us or our counsel in respect of any 
approval or license required for any currency conversion, transfer or distribution. The depositary shall not incur any liability for the content of any 
information submitted to it by us or on our behalf for distribution to ADR holders or for any inaccuracy of any translation thereof, for any investment risk 
associated with acquiring an interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third 
party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of any notice from us. The depositary shall not 
be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or omission of the depositary or in connection 
with any matter arising wholly after the removal or resignation of the depositary. 

Neither we, the depositary nor any of our respective directors, officers, employees, agents or affiliates, nor our company’s supervisors, shall be liable to 
registered holders or beneficial owners for any indirect, special, punitive or consequential damages (including, without limitation, legal fees and expenses) 
or lost profits, in each case of any form incurred by any person or entity (including, without limitation, holders and beneficial owners), whether or not 
foreseeable and regardless of the type of action in which such a claim may be brought. 

In the deposit agreement each party thereto (including, for avoidance of doubt, each holder and beneficial owner and/or holder of interests in ADRs) 
irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the 
depositary and/or us directly or indirectly arising out of or relating to the ordinary shares or other deposited securities, the ADSs or the ADRs, the deposit 
agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, common law or any other theory). 

The depositary and its agents may own and deal in any class of securities of our company and our affiliates and in ADRs. 

Disclosure of Interest in ADSs 

To the extent that the provisions of or governing any deposited securities may require disclosure of or impose limits on beneficial or other ownership of, or 
interests in, deposited securities, other ordinary shares and other securities and may 

 
 
provide for blocking transfer, voting or other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and 
ownership limitations and to comply with any reasonable instructions we may provide in respect thereof. 

Each ADR holder agrees to comply with requests from us pursuant to the laws, rules and regulations of the Cayman Islands, and Singapore, as well as the 
rules and regulations of any stock exchange on which the ordinary shares may hereinafter be registered, traded or listed to provide information, inter alia, as 
to the capacity in which such ADR holder owns ADRs (and ordinary shares as the case may be) and regarding the identity of any other person interested in 
such ADRs and the nature of such interest. 

Books of Depositary 

The depositary or its agent will maintain a register for the registration, registration of transfer, combination and split-up of ADRs, which register shall 
include the depositary’s direct registration system. Registered holders of ADRs may inspect such register at the depositary’s office at all reasonable times, 
but for the purpose of communicating with other ADR holders in the interest of the business of our company or a matter relating to the deposit agreement. 
Such register may be closed at any time or from time to time, when deemed expedient by the depositary. 

The depositary will maintain facilities for the delivery and receipt of ADRs. 

Appointment 

In the deposit agreement, each registered holder of ADRs and each beneficial owner, upon acceptance of any ADSs or ADRs (or any interest in any of 
them) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to: 

•

•

•

be a party to and bound by the terms of the deposit agreement and the applicable ADR or ADRs, 

appoint the depositary its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in 
the deposit agreement and the applicable ADR or ADRs, to adopt any and all procedures necessary to comply with applicable laws and to 
take such action as the depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the deposit 
agreement and the applicable ADR or ADRs, the taking of such actions to be the conclusive determinant of the necessity and 
appropriateness thereof, and 

acknowledge and agree that (i) nothing in the deposit agreement or any ADR shall give rise to a partnership or joint venture among the 
parties thereto nor establish a fiduciary or similar relationship among such parties, (ii) the depositary, its divisions, branches and affiliates, 
and their respective agents, may from time to time be in the possession of non-public information about us, holders, beneficial owners 
and/or their respective affiliates, (iii) the depositary and its divisions, branches and affiliates may at any time have multiple banking 
relationships with us, holders, beneficial owners and/or the affiliates of any of them, (iv) the depositary and its divisions, branches and 
affiliates may, from time to time, be engaged in transactions in which parties adverse to us or the holders or beneficial owners may have 
interests, (v) nothing contained in the deposit agreement or any ADR(s) shall (A) preclude the depositary or any of its divisions, branches or 
affiliates from engaging in such transactions or establishing or maintaining such relationships, or (B) obligate the depositary or any of its 
divisions, branches or affiliates to disclose such transactions or relationships or to account for any profit made or payment received in such 
transactions or relationships, (vi) the depositary shall not be deemed to have knowledge of any information held by any branch, division or 
affiliate of the depositary and (vii) notice to a holder shall be deemed, for all purposes of the deposit agreement, to constitute notice to any 
and all beneficial owners of the ADSs evidenced by such holder’s ADRs. 

 
 
Governing Law, Submission to Jurisdiction and Arbitration 

The deposit agreement, the ADSs and the ADRs are governed by and construed in accordance with the laws of the State of New York without giving effect 
to the application of the conflict of law principles thereof. In the deposit agreement, we have submitted to the jurisdiction of the state and federal courts of 
the State of New York and appointed an agent for service of process on our behalf. Notwithstanding the foregoing, subject to the terms described below, 
including the federal securities law carve-out set forth at the end of this sentence, (i) the depositary may refer any such suit, action or proceedings to 
arbitration in accordance with the provisions of the deposit agreement, and, upon such referral, any such suit, action or proceeding instituted by us shall be 
finally decided in such arbitration rather than in such court, (ii) the depositary may, in its sole discretion, elect to institute any dispute, suit, action, 
controversy, claim or proceeding directly or indirectly based on, arising out of or relating to the deposit agreement or the ADRs or the transactions 
contemplated thereby, including without limitation any question regarding its or their existence, validity, interpretation, performance or termination, against 
any other party or parties to the deposit agreement (including, without limitation, against ADR holders and beneficial owners), by having the matter 
referred to and finally resolved by an arbitration conducted under the terms described below, and (iii) the depositary may in its sole discretion require that 
any dispute, suit, action, controversy, claim, or proceeding of the type described in clause (ii) above, brought against the depositary by any party or parties 
to the deposit agreement (including, without limitation, by ADR holders and beneficial owners ), shall be referred to and finally settled by an arbitration 
conducted under the terms described below; provided however, that to the extent there are specific federal securities law violation aspects to any disputes 
against us and/or the depositary brought by any ADR holder or beneficial owner, the federal securities law violation aspects of such disputes brought by an 
ADR holder and/or beneficial owner against us and/or the depositary may, at the option of such holder, remain in state or federal court in New York, New 
York and all other aspects, claims, disputes, legal suits, actions and/or proceedings brought by such holder against us and/or the depositary, including those 
brought along with, or in addition to, federal securities law violation claims, would be referred to arbitration in accordance with the provisions of the 
deposit agreement. Any such arbitration shall be conducted either in New York, New York in accordance with the Commercial Arbitration Rules of the 
American Arbitration Association or in Hong Kong following the arbitration rules of the United Nations Commission on International Trade Law with the 
Hong Kong International Arbitration Centre serving as the appointing authority, and the language of any such arbitration shall be English. 

Notwithstanding the foregoing, any suit, action or proceeding based on the deposit agreement, the ADSs or the ADRs or the transactions contemplated 
thereby may be instituted by the depositary in any competent court in the Cayman Islands, Singapore and/or the United States. 

By holding an ADS or an interest therein, registered holders of ADRs and beneficial owners each irrevocably agree that subject to the depositary’s rights, 
(i) any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement, the ADSs or the ADRs 
or the transactions contemplated herein, therein or hereby may only be instituted in a state or federal court in New York, New York, and each irrevocably 
waives any objection which it may have to the laying of venue of any such proceeding, and irrevocably submits to the exclusive jurisdiction of such courts 
in any such suit, action or proceeding.
