1.  Risk Factors

The occurrence of any of the events or circumstances described in these risk factors, individually or together with other circum-
stances, could have a material adverse effect on the business, results of operations, financial condition and prospects of the 
Company. These are not the only risks the Company faces. Additional risks and uncertainties not presently known to the Company 
or that it currently considers immaterial or not specific may also impair its business, results of operation and financial condition.

1.1.  Risk Factors Related to Our Financial Position and Need for Additional 

Capital

1.1.1.  WE HAVE INCU RRED SIGNI FICAN T LO SS ES S I N CE OU R I N CE PTI ON AN D EXPECT TO 

INCUR LOSSES FOR THE FORESE EAB LE F UT UR E. WE M AY N EV ER ACH I EV E OR MAI N TAI N 
PROFITABILITY.

We are a clinical-stage biopharmaceutical company with a limited operating history. We do not currently have any approved prod-
ucts and have never generated any revenue from product sales. Since our inception, we have incurred significant operating losses, 
totaling EUR 257.7 million of cumulative losses over the financial years 2017, 2018 and 2019. Our losses resulted principally from 
costs incurred in research and development, preclinical testing, clinical development of our product candidates as well as costs 
incurred for research programs and from general and administrative costs associated with our operations. In addition, we expect 
to continue to incur significant costs associated with our listings in the United States and in Europe. In the future, we intend to 
continue to conduct research and development, preclinical testing, clinical trials and regulatory compliance activities and we intend 
to continue our efforts to establish a sales, marketing and distribution infrastructure. These expenses, together with anticipated 
general and administrative expenses, will result in incurring further significant losses for at least the next several years. Our losses, 
among other things, will continue to cause our working capital and shareholders’ equity to decrease. We anticipate that our expenses 
will increase substantially if and as we execute our business plan as further set out in chapter 3 “Business” on page 56 and further 
and as we experience delays or encounter issues relating thereto, including failed studies, ambiguous trial results, safety issues or 
other regulatory challenges.

To become and remain profitable, we must succeed in developing and eventually commercializing products that generate significant 
revenue. This will require us to be successful in a range of challenging activities, including completing preclinical testing and clinical 
trials of our product candidates, discovering and developing additional product candidates, obtaining regulatory approval for any 
product candidates that successfully complete clinical trials, establishing manufacturing and marketing capabilities and ultimately 
selling any products for which we may obtain regulatory approval. We are only in the preliminary stages of most of these activities. 
We may never succeed in these activities and, even if we do, may never generate revenue that is significant enough to achieve 
profitability. 

Even if we do generate product royalties or product sales, we may never achieve or sustain profitability on a quarterly or annual 
basis. Our failure to achieve or sustain profitability could impair our ability to raise capital, expand our business, diversify our 
product offerings or continue our operations and as such could have a material adverse impact on our business, financial condition 
and results of operations.

AVA I L A BLE TO U S ON ACCEPTA BLE TE R M S OR AT AL L. 

Notwithstanding our significant position of cash and cash like equivalents at the date of this Registration Document, we expect to 
require additional funding in the future to sufficiently finance our operations, to advance development of our product candidates 
and to continue our business activities relating to research and development. Our future capital requirements for efgartigimod, 
cusatuzumab (ARGX-110) or our preclinical programs will depend on many factors, including those set out in the paragraph 4.1.3 
“Liquidity and Capital Resources” on page 126 and further.

8  |  Risk Factors Related to Our Financial Position and Need for Additional Capital

We expect that the costs of development and commercialization will significantly increase due to the extended product development 
roadmap for cusatuzumab as part of our collaboration with Janssen Pharmaceuticals, Inc., or Janssen. Although this collaboration 
agreement provides a joint decision process to approve the development plan as well as the budget, we cannot control the actual 
amounts spent within such approved budget and we cannot control or guarantee that these funds are spent in the most efficient 
way.

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through a 
combination of public or private equity or debt financings or other sources, which may include collaborations with third parties. 
Our ability to raise additional funds will depend on financial, economic and market conditions and other factors, over which we 
may have no or limited control. Adequate additional financing may not be available to us on acceptable terms, or at all. The inability 
for us to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our 
business strategy and as a result we may be forced to delay, reduce or terminate the development or commercialization of all or 
part of our research programs or product candidates, we may be required to significantly curtail, delay or discontinue one or more 
of our research or development programs or the commercialization of any of our product candidates, or be unable to expand our 
operations or otherwise capitalize on our business opportunities, as desired or we may be unable to take advantage of future busi-
ness opportunities, all of which may have a material adverse impact on our business, financial condition and results of operations.

1.2.  Risk Factors Related to the Development and Clinical Testing of Our 

Product Candidates

OR DELAY IN, REGULATORY APPROVAL OR FO R OT HER R EASO N S.

For our clinical trials to succeed and in order to obtain the requisite regulatory approvals to market and sell any of our product 
candidates, we or our collaborators for such candidates must successfully demonstrate through extensive preclinical studies and 
clinical trials that our products are safe, pure and potent or effective in humans. Clinical testing is expensive and can take many years 
to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process and our future 
clinical trial results may not be successful. There is a high failure rate for drugs and biologics proceeding through clinical trials. A 
number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development 
even after achieving promising results in earlier studies, and any such setbacks in our clinical development could have a material 
adverse effect on our business, operating results and financial condition. 

We may experience delays in our ongoing clinical trials, and we do not know whether planned clinical trials will begin on time, 
need to be redesigned, enroll patients on time or be completed on schedule, if at all. Clinical trials can be delayed, suspended, or 
terminated for a large variety of reasons outside our control, including delays of approval from regulatory authorities, institutional 
review boards or ethics committees, delays or failure to recruit or retain patients, failures of third parties to comply with regulatory 
or contractual requirements or issues relating to the quantity, quality or stability of the product candidate.

We could encounter delays, for example if a clinical trial is suspended or terminated by us, by the institutional review boards, or 
IRBs, of the institutions in which such trials are being conducted or ethics committees, by the Data Review Committee, or DRC, or 
Data Safety Monitoring Board, or DSMB, for such trial or by the EMA, the FDA or other regulatory authorities. Such authorities may 
impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance 
with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the EMA, the FDA or 
other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, including 
those relating to the class to which our product candidates belong, failure to demonstrate a benefit from using a drug, changes 
in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience 
delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product 
candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In 
addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and

also allow our competitors to bring products to market before we do or shorten any periods during which we have the exclusive 
right to commercialize our product candidates and impair our ability to commercialize our product candidates and may harm our 
business, results of operations and financial condition. 

Clinical trials must be conducted in accordance with the FDA, the EMA, the PDMA and other applicable regulatory authorities’ legal 
requirements and regulations and are subject to oversight by these governmental agencies and IRBs at the medical institutions where 
the clinical trials are conducted or ethics committees. In addition, clinical trials must be conducted with supplies of our product 
candidates produced under current good manufacturing practices, or cGMP, requirements and other regulations. Furthermore, we 
rely on contract research organizations or 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. We 
depend on our collaborators and on medical institutions and CROs to conduct our clinical trials in compliance with Good Clinical 
Practice, or GCP, requirements. To the extent our collaborators or the CROs or investigators fail to enroll participants for our clinical 
trials, fail to conduct the study to GCP standards or are delayed for a significant time in the execution of trials, including achieving 
full enrollment, we may be affected by increased costs, program delays or both, which may harm our business. In addition, clinical 
trials that are conducted in countries outside the European Union and the United States may subject us to further delays and 
expenses as a result of increased shipment costs, additional regulatory requirements and the engagement of non-European Union 
and non-U.S. CROs, as well as expose us to risks associated with clinical investigators who are unknown to the FDA or the EMA, and 
different standards of diagnosis, screening and medical care. 

Before we can commence clinical trials for a product candidate, we must complete extensive preclinical testing and studies that 
support our planned Investigational New Drug applications, or INDs, in the United States, or a Clinical Trial Authorization Applications, 
or CTAs, in Europe. We cannot be certain of the timely completion or outcome of our preclinical testing and studies and cannot 
predict if the EMA, the FDA or the PMDA will accept our proposed clinical programs or if the outcome of our preclinical testing and 
studies will ultimately support the further development of these product candidates. Thus, we cannot be sure that we will be able 
to submit INDs or CTAs for our preclinical programs on the timelines we expect, if at all, and we cannot be sure that submission of 
INDs or CTAs will result in the EMA, the FDA or the PMDA allowing clinical trials to begin. 

Even if clinical trials do begin for these preclinical programs, our development efforts may not be successful, and clinical trials that 
we conduct or that third parties conduct on our behalf may not demonstrate sufficient safety, purity and potency or efficacy to 
obtain the requisite regulatory approvals for any of our product candidates or product candidates employing our technology. Even 
if we obtain positive results from preclinical studies or initial clinical trials, we may not achieve the same success in future trials. 

Any of these occurrences may harm our business, results of operations and financial condition significantly. In addition, 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 of our product candidates or result in the development of our product candidates being stopped early.

If the FDA, the EMA, the PDMA or a comparable foreign regulatory authority approves any of our product candidates, the manufac-
turing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for 
the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety 
and other post-marketing information and reports, registration, as well as continued compliance with cGMPs and GCPs for any 
clinical trials that we conduct post-approval, all of which may result in significant expense and limit our ability to commercialize 
such products. In addition, any regulatory approvals that we receive for our product candidates may also be subject to limitations 
on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements 
for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of 
the product candidate. 

10  |  Risk Factors Related to the Development and Clinical Testing of Our Product Candidates

Our product candidates are classified as biologics in the United States and, therefore, can only be sold if we obtain a BLA from the 
FDA and therefore cannot be sold if we do not obtain a BLA. The holder of a BLA is obligated to monitor and report adverse events 
and any failure of a product to meet the specifications in the BLA. The holder of a BLA must also submit new or supplemental 
applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. 

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

1.2.3.  OUR PRODUCT CAN DIDATES MAY H AV E S ER I O US ADV E R S E, UN D ES I R AB LE O R 

UNACCEPTABLE S IDE EFF ECTS OR EV EN D EATH.

Undesirable side effects that may be caused by our product candidates could cause us or regulatory authorities to interrupt, delay or 
halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, the EMA, the 
PDMA or other comparable foreign authorities. While our pre-clinical and clinical studies for our product candidates to date have 
generally been well tolerated from a risk-benefit perspective, we have observed adverse events and treatment emergent adverse 
events in our clinical studies to date, and we may see additional adverse events and treatment emergent adverse events or TEAEs 
in our ongoing and future trials, which may be more serious than those observed to date, and as a result, our ongoing and future 
trials may be negatively impacted. 

The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in 
potential product liability claims. Any of these occurrences may harm our business, results of operation and financial condition 
significantly. Further, because all of our product candidates and preclinical programs, other than efgartigimod, are based on our 
SIMPLE AntibodyTM platform, any adverse safety or efficacy findings related to any product candidate or preclinical program may 
adversely impact the viability of our other product candidates or preclinical programs. 

Additionally, if any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable 
side effects caused by such products, a number of potentially significant negative consequences could result, including:

• 
• 

• 

regulatory authorities may withdraw approvals of such products and require us to take our approved product off the market; 
regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to 
physicians and pharmacies; 
regulatory authorities may require a medication guide outlining the risks of such side effects for distribution to patients, or that 
we implement a risk evaluation and mitigation strategy, or REMS, plan to ensure that the benefits of the product outweigh its 
risks; 

•  we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of 

the product; 

sales of the product may decrease significantly; 

•  we may be subject to limitations on how we may promote the product; 
• 
•  we may be subject to litigation or product liability claims; and 
•  our reputation may suffer. 

Any of these events could prevent us, our collaborators or our potential future partners from achieving or maintaining market 
acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay 
or prevent us from generating significant revenue from the sale of our products.

EFFORTS.

The market for pharmaceutical products is highly competitive. Our competitors include many established pharmaceutical companies, 
biotechnology companies, universities and other research or commercial institutions, many of which have substantially greater 
financial, research and development resources than we have. A detailed analysis of the intense competition we face in the auto-
immune field, the field of leukemia and lymphoma and the monoclonal antibody drug discovery field is set out in paragraph 3.1.3 
“Competitive Position” on page 59 and further. Large pharmaceutical companies, in particular, have extensive experience in clinical 
testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. Smaller and early stage 
companies may also prove to be significant competitors, particularly through collaborative arrangements with large and estab-
lished companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, 
establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or 
necessary for, the development of our products. 

The fields in which we operate are characterized by rapid technological change and innovation. There can be no assurance that 
our competitors are not currently developing, or will not in the future develop, technologies and products that are equally or 
more effective or are more economically attractive than any of our current or future technology or product. Competing products 
or technology platforms may gain faster or greater market acceptance than our products or technology platforms and medical 
advances or rapid technological development by competitors may result in our product candidates or technology platforms becoming 
non-competitive or obsolete before we are able to recover our research and development and commercialization expenses. If we, 
our product candidates or our technology platforms do not compete effectively, it is likely to have a material adverse effect on our 
business, financial condition and results of operation.

1.2.5.  WE DEPEND ON ENROLLMENT OF PAT I EN T S I N O U R C LI N I CAL TR I ALS FO R O UR P RO DUCT 

CANDIDATES.

Identifying and qualifying patients to participate in our clinical trials is critical to our success. Patient enrollment depends on many 
factors, including the size and nature of the patient population, eligibility criteria for the trial, the proximity of patients to clinical 
sites, the design of the clinical protocol, the availability of competing clinical trials, the availability of new drugs approved for the 
indication the clinical trial is investigating, and clinicians’ and patients’ perceptions as to the potential advantages of the drug being 
studied in relation to other available therapies. Since some of our product candidates are focused on addressing rare diseases and 
conditions, there are limited patient pools available to complete our clinical trials in a timely and cost-effective manner. For example, 
the number of patients suffering from each of MG; ITP; PV; T-cell lymphoma, or TCL; and acute myeloid leukemia, or AML, is small 
and has not been established with precision. If the actual number of patients with these disorders is smaller than we anticipate, we 
may encounter difficulties in enrolling patients in our clinical trials, thereby delaying or preventing development and approval of 
our drug candidates. Even once enrolled we may be unable to retain a sufficient number of patients to complete any of our trials. 

Furthermore, our efforts to build relationships with patient communities may not succeed, which could result in delays in patient 
enrollment in our clinical trials. In addition, any negative results we may report in clinical trials of our drug candidate may make it 
difficult or impossible to recruit and retain patients in other clinical trials of that same drug candidate. Delays in the completion 
of any clinical trial of our product candidates will increase our costs, slow down our product candidate development and approval 
process and delay or potentially jeopardize our ability to commence product sales and generate revenue. In addition, some of the 
factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial 
of regulatory approval of our product candidates.

In December 2019, a novel strain of a virus named SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), or coronavirus, which 
causes coronavirus disease, or COVID-19, was reported to have surfaced in Wuhan, China and has reached multiple other regions and 
countries, including Europe and the United States. The COVID-19 pandemic is evolving, and to date has led to the implementation of 
various responses, including government-imposed quarantines, travel restrictions and other public health safety measures. 

12  |  Risk Factors Related to the Development and Clinical Testing of Our Product Candidates

The continued spread of COVID-19 or other global health matters, such as pandemics, could adversely impact our clinical trials 
or preclinical studies. For instance, the COVID-19 outbreak could impair our ability to recruit and retain patients and principal 
investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak occurs in their 
geography or due to prioritization of hospital resources toward the outbreak and restrictions in travel. Furthermore, some patients 
may be unwilling to enroll in our trials or be unable to comply with clinical trial protocols if quarantines or travel restrictions impede 
patient movement or interrupt healthcare services. COVID-19 may also negatively affect the operations of third-party CROs that 
we rely upon to carry out our clinical trials or the operations of our third-party manufacturers, which could result in delays or 
disruptions in the supply of our product candidates. Any negative impact COVID-19 has to patient enrollment or treatment or the 
timing and execution of our clinical trials could cause costly delays to our clinical trial activities, which could adversely affect our 
ability to obtain regulatory approval for and to commercialize our product candidates.

1.2.7.  WE MAY BECOME EXPOSED TO COS T LY AN D DAMAG I N G L I ABI L I TY CLAI M S.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manu-
facturing, marketing and use of pharmaceutical products. Currently, we have no products that have been approved for commercial 
sale; however, the current and future use of product candidates by us and our corporate collaborators in clinical trials, and the 
potential sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients who 
use the product, healthcare providers, pharmaceutical companies, our corporate collaborators or others selling such products. Any 
claims against us, regardless of their merit, could be difficult and costly to defend and could materially adversely affect the market 
for our product candidates or any prospects for commercialization of our product candidates. Although the clinical trial process is 
designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval, may exhibit 
unforeseen side effects. If any of our product candidates were to cause adverse side effects during clinical trials or after approval 
of the product candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings 
that identify known potential adverse effects and patients who should not use our product candidates. Regardless of the merits or 
eventual outcome, liability claims may result in:

initiation of investigations by regulators; 
costs to defend or settle the related litigation; 

•  decreased demand for our products due to negative public perception; 
•  damage to our reputation; 
•  withdrawal of clinical trial participants or difficulties in recruiting new trial participants; 
• 
• 
•  a diversion of management’s time and our resources; 
• 
•  product recalls, withdrawals or labeling, marketing or promotional restrictions; 
• 
• 

loss of revenues from product sales; and 
the inability to commercialize any of our product candidates, if approved.

substantial monetary awards to trial participants or patients; 

Although we maintain product liability insurance for our product candidates, it is possible that our liabilities could exceed our 
insurance coverage. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing 
approval for any of our product candidates. However, we may not be able to maintain insurance coverage at a reasonable cost or 
to obtain insurance coverage that will be adequate to satisfy any liability that may arise. If a successful product liability claim or 
series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to 
cover such claims and our business operations could be impaired. 

Should any of the events described above occur, this could have a material adverse effect on our business, financial condition and 
results of operations.

In the United States, the European Union and other foreign jurisdictions, there have been a number of legislative and regulatory 
changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to 
be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs and improve the quality 
of healthcare. A detailed description of the relevant legislative and regulatory initiatives and changes is contained in paragraph 3.7.6 
“Healthcare Reform” on page 110 and further. If such legislative and/or regulatory initiatives and changes would lead to increased 
restrictions on marketing our products, or lead to limiting the funds available for healthcare in jurisdictions relevant to us which 
may reduce reimbursement levels and is likely to affect the prices we may set, we would be negatively impacted in our ability to 
successfully and profitably market our product candidates. 

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or adminis-
trative action, either in the United States or abroad. If we or our collaborators are slow or unable to adapt to changes in existing 
requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory 
compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or 
sustain profitability, which would adversely affect our business.

Although we do not currently have any products on the market, our current and future operations may be directly, or indirectly 
through our customers and third-party payors, subject to various U.S. federal and state healthcare laws and regulations, including, 
without limitation, the U.S. federal Anti-Kickback Statute. Healthcare providers, physicians and others play a primary role in the 
recommendation and prescription of any products for which we obtain marketing approval. These laws may impact, among other 
things, our proposed sales, marketing and education programs and constrain our business and financial arrangements and relation-
ships with third-party payors, healthcare professionals who participate in our clinical research program, healthcare professionals 
and others who recommend, purchase, or provide our approved products, and other parties through which we market, sell and 
distribute our products for which we obtain marketing approval. In addition, we may be subject to patient data privacy and security 
regulation by both the U.S. federal government and the other states and countries in which we conduct our business. Finally, our 
current and future operations are subject to additional healthcare-related statutory and regulatory requirements and enforcement 
by foreign regulatory authorities in jurisdictions in which we conduct our business. The shifting compliance environment and the 
need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance or 
reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements. We 
have no experience in the sale or marketing of pharmaceutical products and, in light of any future approval and commercialization, 
we will need to continue building an internal program to ensure compliance with the different health care laws and regulations. The 
establishment of an internal compliance program will involve substantial costs and the program may not be successful in complying 
with the different reporting requirements. For an overview of some of the laws and regulations which may affect our ability to 
operate, please refer to the paragraph 3.7.5 “Healthcare Law and Regulation” on page 107 and further.

It is possible that governmental authorities will conclude that our business practices may 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 are 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, exclusion of drugs from government funded 
healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a 
corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, reputational harm 
and the curtailment or restructuring of our operations. Defending against any such actions can be costly and time-consuming and 
may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions 

14  |  Risk Factors Related to Commercialization of Our Product Candidates

that may be brought against us, our business may be impaired. Further, if any of the physicians or other healthcare providers or 
entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, 
civil or administrative sanctions, including exclusions from government funded healthcare programs.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare 
reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently 
increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of 
investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring business arrangements comply with 
applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time and resource 
consuming and can divert a company’s attention from the business. For further details and examples, we refer to paragraph 3.7.5 
“Healthcare Law and Regulation” on page 107 and further.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations 
will involve substantial costs. For example, the provision of benefits or advantages to physicians to induce or encourage the 
prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is generally not permitted in 
the countries that form part of the European Union. Some European Union Member States, like the United Kingdom, through the 
United Kingdom Bribery Act 2010, have enacted laws explicitly prohibiting the provision of these types of benefits and advantages. 
Infringements of these laws can result in substantial fines and imprisonment. Any action against us for violation of these laws, even 
if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from 
the operation of our business.

CONDITIONS.

In Europe, Directive 95/46/EC of the European Parliament and of the Council of October 24, 1995 on the protection of individuals 
with regard to the processing of personal data and on the free movement of such data, or the Directive, and Directive 2002/58/EC 
of the European Parliament and of the Council of July 12, 2002 concerning the processing of personal data and the protection of 
privacy in the electronic communications sector (as amended by Directive 2009/136/EC), or the e-Privacy-Directive, have required 
the European Union, or EU member states, to implement data protection laws to meet strict privacy requirements. Violations of 
these requirements can result in administrative measures, including fines, or criminal sanctions. The e-Privacy-Directive will likely 
be replaced in time by a new e-Privacy-Regulation which may impose additional obligations and risk for our business. 

Beginning on May 25, 2018, the Directive was replaced by Regulation (EU) 2016/679 of the European Parliament and of the Council 
of April 27, 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement 
of such data, or the GDPR. The GDPR imposes a broad range of strict requirements on companies subject to the GDPR, such as us, 
including requirements relating to having legal bases for processing personal information relating to identifiable individuals and 
transferring such information outside the European Economic Area, or the EEA, including to the United States, providing details 
to those individuals regarding the processing of their personal information, keeping personal information secure, having data 
processing agreements with third parties who process personal information, responding to individuals’ requests to exercise their 
rights in respect of their personal information, reporting security breaches involving personal data to the competent national data 
protection authority and affected individuals, appointing data protection officers, conducting data protection impact assessments, 
and recordkeeping. The GDPR substantially increases the penalties to which we could be subject in the event of any non-compliance, 
including fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor 
offenses, or up to 20,000,000 Euros or up to 4% of our total worldwide annual turnover for more serious offenses. Given the new 
law, we face uncertainty as to the exact interpretation of the new requirements, and we may be unsuccessful in implementing all 
measures required by data protection authorities or courts in interpretation of the new law. 

In particular, national laws of member states of the EU are in the process of being adapted to the requirements under the GDPR, 
thereby implementing national laws which may partially deviate from the GDPR and impose different obligations from country to 
country, so that we do not expect to operate in a uniform legal landscape in the EU. Also, in the field of handling genetic data, the 
GDPR specifically allows national laws to impose additional and more specific requirements or restrictions, and European laws have 
historically differed quite substantially in this field, leading to additional uncertainty.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXRISK FACTORSWe must also ensure that we maintain adequate safeguards to enable the transfer of personal data outside of the EEA, in particular 
to the United States in compliance with European data protection laws, including the GDPR. We expect that we will continue to 
face uncertainty as to whether our efforts to comply with our obligations under European privacy laws will be sufficient. If we are 
investigated by a European data protection authority, we may face fines and other penalties. Any such investigation or charges by 
European data protection authorities could have a negative effect on our existing business and on our ability to attract and retain 
new clients or pharmaceutical partners. We may also experience hesitancy, reluctance, or refusal by European or multinational 
clients or pharmaceutical partners to continue to use our products and solutions due to the potential risk exposure as a result of 
the current (and, in particular, future) data protection obligations imposed on them by certain data protection authorities in inter-
pretation of current law, including the GDPR. Such clients or pharmaceutical partners may also view any alternative approaches to 
compliance as being too costly, too burdensome, too legally uncertain, or otherwise objectionable and therefore decide not to do 
business with us. Any of the foregoing could materially harm our business, prospects, financial condition and results of operations.

1.3.4.  IF WE FAI L TO OBTAIN ORPHAN DRUG DE SI GN ATI O N OR O BTAI N OR M AI N TAI N OR P HAN 

DRUG EXCLUSIVITY FOR OUR PROD UCT S, O UR CO MPE T I TO R S M AY S EL L PRODUCT S TO TREAT 
THE SAME CON DITIONS AND OUR R E VEN U E WI L L BE R EDU CED.

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is intended to treat a rare disease or condition, 
defined as a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the 
United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the 
United States. In the European Union, after a recommendation from the EMA’s Committee for Orphan Medicinal Products, or 
COMP, the European Commission grants orphan drug designation to promote the development of products that are intended for 
the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 
10,000 persons in the European Union. Additionally, designation is granted for products intended for the diagnosis, prevention or 
treatment of a life-threatening, seriously debilitating or serious and chronic condition when, without incentives, it is unlikely that 
sales of the drug in the European Union would be sufficient to justify the necessary investment in developing the drug or biological 
product or where there is no satisfactory method of diagnosis, prevention or treatment, or, if such a method exists, the medicine 
must be of significant benefit to those affected by the condition. 

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards 
clinical trial costs, tax advantages and userfee waivers. In addition, if a product receives the first FDA approval for the indication for 
which it has orphan designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other 
application to market the same drug for the same indication for a period of seven years, except in limited circumstances, such as 
a showing of clinical superiority over the product with orphan exclusivity or where the manufacturer is unable to assure sufficient 
product quantity. In the European Union, orphan drug designation entitles a party to financial incentives such as reduction of fees 
or fee waivers and ten years of market exclusivity following drug or biological product approval. This period may be reduced to six 
years if the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficiently profitable 
not to justify maintenance of market exclusivity. If we fail to obtain or if we lose orphan drug status for one or more of our product 
candidates, the aforementioned incentives and market exclusivity may not or no longer be available to us, which is likely to increase 
the overall cost of development and to decrease the competitive position of such product candidate.

We may from time to time seek orphan drug designation in the United States or Europe for certain indications addressed by our 
product candidates. For example, in September 2017, the FDA granted orphan drug designation for the use of efgartigimod for 
the treatment of MG. Even if we are able to obtain orphan designation, we may not be the first to obtain marketing approval for 
such indication due to the uncertainties associated with developing pharmaceutical products. In addition, exclusive marketing 
rights in the United States may be limited if we seek approval for an indication broader than the orphan-designated indication or 
may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable 
to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Further, even if we 
obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because 
different drugs with different active moieties can be approved for the same condition. Even after an orphan drug is approved, the 
FDA or the EMA can subsequently approve the same drug with the same active moiety for the same condition if the FDA or the 
EMA concludes that the later drug is safer, more effective, or makes a major contribution to patient care. Orphan drug designation 
neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory 
review or approval process.

1.3.5.  WE MAY NOT OBTAIN OR MAIN TAI N ADEQ UAT E COVER AGE O R R EI M B UR SE MEN T STATUS FOR 

OUR PRODUCT C ANDIDATES.

Even if our product candidates are approved for marketing, sales of such product candidates will depend, in part, on the extent to 
which third-party payors, including government health programs in the United States (such as Medicare and Medicaid) and other 
countries, commercial health insurers, and managed care organizations, provide coverage and establish adequate reimbursement 
levels for such product candidates. Moreover, increasing efforts by governmental and third-party payors in the European Union, 
the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level 
of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product 
candidates. A detailed analysis of some of the most relevant developments and challenges regarding coverage and reimbursement 
is set out in the paragraph 3.7.4 “Coverage, Pricing and Reimbursement” on page 105 and further of this Registration Document.

Limitations on reimbursement and reimbursement levels may diminish or prevent altogether any significant demand for our products 
and/or may prevent us entirely from entering certain markets, which would prevent us from generating significant revenues or 
becoming profitable, which would adversely affect our business, financials and results of operations.

1.3.6.  THE FUTURE COMMERCIAL SUCCESS O F O UR P ROD U CT CAN DI DATE S W I LL DEP E N D O N TH E

When available on the market, our products may not achieve an adequate level of acceptance by physicians, patients and the 
medical community, and we may not become profitable. In addition, efforts to educate the medical community and third-party 
payers on the benefits of our products may require significant resources and may never be successful which would prevent us 
from generating significant revenues or becoming profitable. Market acceptance of our future products by physicians, patients 
and healthcare payers will depend on a number of factors, many of which are beyond our control, including, but not limited to:

the wording of the product label; 
changes in the standard of care for the targeted indications for any product candidate; 
sales, marketing and distribution support; 

• 
• 
• 
•  potential product liability claims; 
•  acceptance by physicians, patients and healthcare payers of each product as safe, effective and cost-effective; 
• 
•  prevalence and severity of adverse events or publicity; 
• 

relative convenience, ease of use, ease of administration and other perceived advantages over alternative products; 

limitations, precautions or warnings listed in the summary of product characteristics, patient information leaflet, package 
labeling or instructions for use; 
the cost of treatment with our products in relation to alternative treatments; 
the extent to which products are approved for inclusion and reimbursed on formularies of hospitals and managed care orga-
nizations; and 

• 
• 

•  whether our products are designated in the label, under physician treatment guidelines or under reimbursement guidelines as 

a first-line, second-line, or third-line or last-line therapy. 

If our product candidates fail to gain market acceptance, this will have a material adverse impact on our ability to generate revenues. Even 
if some products achieve market acceptance, the market may prove not to be large enough to allow us to generate significant revenues.

Our current and future arrangements with providers, researchers, consultants, third-party payors and customers are subject to 
broadly applicable national, federal and state fraud and abuse, anti-kickback, false claims, transparency and patient privacy laws and 
regulations and other healthcare laws and regulations that may constrain our business and/or financial arrangements. We will be 
required to spend substantial time and money to ensure that our business arrangements with third parties comply with applicable 
healthcare laws and regulations. Recent healthcare reform legislation has strengthened these federal and state healthcare laws 
(for more information see paragraph 3.7.5 “Healthcare Law and Regulation” on page 107 and further). Violations of these laws can

imprisonment and exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, 
additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement 
to resolve allegations of non-compliance with these laws, reputational harm, and the required curtailment or restructuring of our 
operations. Moreover, we expect that there will continue to be federal and state laws and regulations, proposed and implemented, 
that could impact our business, financial condition and results of operations.

PRODUCTS.

We do not have a sales or marketing infrastructure and have no experience in the sale or marketing of pharmaceutical products. To 
achieve commercial success for any approved product, we must develop or acquire a sales and marketing organization, outsource 
these functions to third parties or enter into collaboration arrangements with third parties. We may decide to establish our own 
sales and marketing capabilities and promote our product candidates if and when regulatory approval has been obtained in the 
major European Union countries and the United States. There are risks involved should we decide to establish our own sales and 
marketing capabilities or enter into arrangements with third parties to perform these services. Even if we establish sales and 
marketing capabilities, we may fail to launch our products effectively or to market our products effectively. In addition, recruiting 
and training a sales force is expensive and time consuming and could delay any product launch. In the event that any such launch is 
delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses, 
and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. 

If we enter into arrangements with third parties to perform sales and marketing services, our product revenues or the profitability 
of these product revenues to us could be lower than if we were to market and sell any products that we develop ourselves. Such 
collaborative arrangements may place the commercialization of our products outside of our control and would make us subject to 
a number of risks including that we may not be able to control the amount or timing of resources that our collaborative partner 
devotes to our products or that our collaborator’s willingness or ability to complete its obligations, and our obligations under our 
arrangements may be adversely affected by business combinations or significant changes in our collaborator’s business strategy. 
In addition, we may not be successful in entering into arrangements with third parties to sell and market our products or may be 
unable to do so on terms that are favorable to us. Acceptable third parties may fail to devote the necessary resources and attention 
to sell and market our products effectively. If we do not establish sales and marketing capabilities successfully, either on our own or 
in collaboration with third parties, we may not be successful in commercializing our products, which in turn would have a material 
adverse effect on our business, financial condition and results of operations.

1.3.9.  OUR PRODUCT CAN DIDATES FOR W HI CH WE I N T EN D TO S EE K APP ROVAL AS BI O LO G I C 

PRODUCTS MAY FACE COMPETI T I ON S O ON ER TH AN AN T I CI PAT ED.

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated approval pathway for biological 
products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application 
for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first 
licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the 
date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market 
a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s 
own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency 
of their product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, 
implementation and meaning are subject to uncertainty. See also chapter 2 “Business”.

We believe that any of our product candidates approved as a biological product under a BLA should qualify for the 12-year period 
of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the 
FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity 
for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity 
provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar product, once approved, will 
be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological 
products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.

The international biopharmaceutical and medical technology industry is subject to a high level of regulation by the FDA, the EMA, 
the PMDA and other comparable foreign authorities and by other national or supra-national regulatory authorities. Applicable 
regulations impose substantial requirements covering nearly all aspects of our activities and the activities of our partners and 
licensees, notably on research and development, manufacturing, preclinical tests, clinical trials, labeling, marketing, sales, storage, 
record keeping, promotion and pricing of our product candidates. 

Failure to (timely) comply with regulatory requirements could have far reaching consequences for us, including significant delay in 
our product development as a result of regulatory authorities recommending non-approval or restrictions on approval of a product 
candidate. Any failure or delay of any of our product candidates in clinical studies or to receive regulatory approval could have 
a material adverse effect on our business, results of operations and financial condition. If any of our product candidates fails to 
obtain approval on the basis of any applicable condensed regulatory approval process, this will prevent such product candidate from 
obtaining approval in a shortened time frame, or at all, resulting in increased expenses which would materially harm our business.

Regulations differ substantially per jurisdiction and are subject to constant change. In order to market our future products in regions 
such as the European Economic Area, United States of America, Asia Pacific and many other foreign jurisdictions, we must obtain 
separate regulatory approvals. The approval procedures vary among countries and can require additional clinical testing, and the 
time required to obtain approval may differ from that required to obtain approval. Moreover, clinical studies conducted in one 
country may not be accepted by regulatory authorities in other countries. Approval by the EMA, the FDA or the PMDA does not 
ensure approval by the comparable foreign authorities in other countries, and approval by one or more foreign regulatory authorities 
does not ensure approval by regulatory authorities in other foreign countries or by the EMA, the FDA or the PMDA. 

There can be no assurance that our product candidates will fulfil the criteria required to obtain necessary regulatory approval to 
access the market. Also, at this time, we cannot guarantee or know the exact nature, precise timing and detailed costs of the efforts 
that will be necessary to complete the remainder of the development of our research programs and products candidates. Each 
of the FDA, the EMA, the PDMA and other comparable foreign authorities may impose its own requirements, may discontinue an 
approval or revoke a license, may refuse to grant approval, or may require additional data before granting approval, notwithstanding 
that approval may have been granted by the FDA, the EMA, the PDMA or one or more other comparable foreign authority. The 
FDA, the EMA, the PDMA or other comparable foreign authorities may also approve a product candidate for fewer or more limited 
indications or patient sub-segments than requested or may grant approval subject to the performance of post-marketing studies. 
The EMA’s, the FDA’s or other regulatory authority’s approval may be delayed, limited or denied for a number of reasons, most of 
which are beyond our control. Such reasons could include, among others, the production process or site not meeting the applicable 
requirements for the manufacture of regulated products, or the products not meeting applicable requirements for safety, purity or 
potency, or efficacy, during the clinical development stage or after marketing. The FDA, the EMA, the PDMA and other comparable 
foreign authorities have substantial discretion in the approval process and determining when or whether regulatory approval will 
be obtained for any of our product candidates. Any of the FDA, the EMA, the PDMA and other comparable foreign authorities may 
disagree with our interpretation of data submitted for their review. Even if we believe the data collected from clinical trials of our 
product candidates are promising, such data may not be sufficient to support approval by the FDA, the EMA, the PDMA or any 
other regulatory authority. 

We and our collaborative partners are, or may become subject to, numerous ongoing other regulatory obligations, such as data 
protection, environmental, health and safety laws and restrictions on the experimental use of animals. The costs of compliance 
with such applicable regulations, requirements or guidelines could be substantial, and failure to comply could result in sanctions, 
including fines, injunctions, civil penalties, denial of applications for marketing authorization of our products, delays, suspension 

Risk Factors Related to Our Business and Industry    |  19 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXRISK FACTORSor withdrawal of approvals, license revocation, seizures or recalls of products, operating restrictions and criminal prosecutions, 
any of which could significantly increase our or our collaborative partners’ costs or delay the development and commercialization 
of our product candidates. 

The time required to obtain approval by the FDA, the EMA, the PDMA and comparable foreign authorities is unpredictable but 
typically takes many years, if obtained at all, following the commencement of clinical trials and depends upon numerous factors, 
including the substantial discretion of the regulatory authorities.

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

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 materially harm the commercial prospects for our product candidates.

Our operations, including our research, development, testing and manufacturing activities, are subject to numerous environmental, 
health and safety laws and regulations. These laws and regulations govern, among other things, the controlled use, handling, release 
and disposal of and the maintenance of a registry for, hazardous materials and biological materials, such as chemical solvents, 
human cells, carcinogenic compounds, mutagenic compounds and compounds that have a toxic effect on reproduction, laboratory 
procedures and exposure to blood-borne pathogens. If we fail to comply with such laws and regulations, we could be subject to 
fines or other sanctions. 

We face a risk of environmental liability inherent in our current and historical activities, including liability relating to releases of or 
exposure to hazardous or biological materials. Environmental, health and safety laws and regulations are becoming more stringent. 
We may be required to incur substantial expenses in connection with future environmental compliance or remediation activities, 
in which case, our production and development efforts may be interrupted or delayed, and our financial condition and results of 
operations may be materially adversely affected.

We are exposed to the risk that our employees, independent contractors, principal investigators, CROs, consultants, vendors and 
collaboration partners may engage in fraudulent conduct or other illegal activities. Misconduct by these parties could include 
intentional, reckless and negligent conduct or unauthorized activities that violate: (i) the regulations of the FDA, the EMA, the 
PDMA and other comparable foreign authorities, including those laws that require the reporting of true, complete and accurate 
information to such authorities; (ii) manufacturing standards; (iii) federal and state data privacy, security, fraud and abuse and 
other healthcare laws and regulations in the United States and in other countries; or (iv) laws that require the reporting of true, 
complete and accurate financial information and data. Specifically, sales, marketing and business arrangements in the healthcare 
industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other 
abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promo-
tion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws could also 
involve the improper use or misrepresentation of information obtained in the course of clinical trials or creating fraudulent data 
in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. 
It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take 
to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us 
from governmental investigations or other actions or lawsuits stemming from a failure to comply with such laws or regulations. 

20  |  Risk Factors Related to Our Business and Industry

Additionally, we are subject to the risk that a person could allege such fraud or other misconduct, even if none occurred. If any 
such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could 
have a significant impact on our business, results of operations and financial condition, including the imposition of significant civil, 
criminal and administrative penalties, damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, 
Medicaid and other U.S. or international healthcare programs, individual imprisonment, additional reporting requirements and 
oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance 
with these laws, other sanctions, contractual damages, reputational harm, diminished profits and future earnings and curtailment 
of our operations, any of which could adversely affect our ability to operate our business and our results of operations. Due to the 
highly regulated environment in which we operate and our heavy reliance on approval of our products by governmental entities 
and healthcare providers, reputational risks related to the misconduct or other improper behavior as described above are likely to 
have a bigger impact on us than on most companies operating in other industries.

If any of our product candidates are approved for commercial sale, we will be highly dependent upon consumer perceptions of 
the safety and quality of our products. We could be adversely affected if we were subject to negative publicity or if any of our 
products or any similar products distributed by other companies prove to be, or are asserted to be, harmful to patients. Because of 
our dependence upon consumer perception, any adverse publicity associated with illness or other adverse effects resulting from 
patients’ use or misuse of our products or any similar products distributed by other companies could have a material adverse impact 
on our business, prospects, financial condition and results of operations. 

Future adverse events in research into the cancer, inflammation and severe autoimmune diseases that we focus our research 
efforts on, or the biopharmaceutical industry more generally, could also result in greater governmental regulation, stricter labeling 
requirements and potential regulatory delays in the testing or approvals of our products. Any increased scrutiny could delay or 
increase the costs of obtaining regulatory approval for our product candidates.

Although a substantial amount of our efforts will focus on the continued preclinical and clinical testing and potential approval of 
our product candidates in our current pipeline, a key element of our long-term growth strategy is to develop and market additional 
products and product candidates. Because we have limited financial and managerial resources, research programs to identify product 
candidates will require substantial additional technical, financial and human resources, whether or not any product candidates are 
ultimately identified. The success of this strategy depends partly upon our ability to identify, select and develop promising product 
candidates and products. Our technology platforms may fail to discover and to generate additional product candidates that are 
suitable for further development. All product candidates are prone to risks of failure typical of pharmaceutical product development, 
including the possibility that a product candidate may not be suitable for clinical development as a result of its harmful side effects, 
limited efficacy or other characteristics that indicate that it is unlikely to be a product that will receive approval by the FDA, the EMA, 
the PMDA and other comparable foreign regulatory authorities and achieve market acceptance. If we do not successfully develop and 
commercialize product candidates based upon our technological approach, we may not be able to obtain product or collaboration 
revenues in future periods, which would adversely affect our business, prospects, financial condition and results of operations. 

Our long-term growth strategy to develop and market additional products and product candidates is heavily dependent on precise, 
accurate and reliable scientific data to identify, select and develop promising pharmaceutical product candidates and products. 
Our business decisions may therefore be adversely influenced by improper or fraudulent scientific data sourced from third parties. 
Any irregularities in the scientific data used by us to determine our focus in research and development of product candidates and 
products could have a material adverse effect on our business, prospects, financial condition and results of operations.

INTERRUPTIONS OR OT HER DI SAS TE R S.

Our product candidates are biologics and require processing steps that are more difficult than those required for most chemical 
pharmaceuticals. Accordingly, multiple steps are needed to control the manufacturing processes. Problems with these manufacturing 
processes, even minor deviations from the normal process or from the materials used in the manufacturing process, which may not 
be detectable by us in a timely manner, could lead to product defects or manufacturing failures, resulting in lot failures, product 
recalls, product liability claims and insufficient inventory. 

Also, certain raw materials or other products necessary for the manufacture and formulation of our product candidates, some of 
which are difficult to source, are provided by single-source unaffiliated third-party suppliers. In addition, we rely on certain third 
parties to perform filling, finishing, distribution, laboratory testing and other services related to the manufacture of our product 
candidates, and to supply various raw materials and other products. We would be unable to obtain these raw materials, other 
products, or services for an indeterminate period of time if any of these third parties were to cease or interrupt production or 
otherwise fail to supply these materials, products, or services to us for any reason, including due to regulatory requirements or 
actions (including recalls), adverse financial developments at or affecting the supplier, failure by the supplier to comply with cGMPs, 
contamination, business interruptions, or labor shortages or disputes. In any such circumstances, we may not be able to engage a 
backup or alternative supplier or service provider in a timely manner or at all. This, in turn, could materially and adversely affect 
our ability to supply product candidates, which could materially and adversely affect our business, financial condition and results 
of operations. 

Certain of the raw materials required in the manufacture and the formulation of our product candidates may be derived from 
biological sources, including mammalian tissues, bovine serum and human serum albumin. There are certain European regulatory 
restrictions on using these biological source materials. If we are required to substitute for these sources to comply with European 
regulatory requirements, our clinical development or commercial activities may be delayed or interrupted.

AND PERFORMANCE.

Public health crises such as pandemics or similar outbreaks could adversely impact our business. To date, the outbreak of COVID-19 
has already resulted in extended shutdowns of certain businesses in many countries all over the world. The spread of COVID-19 
has impacted the global economy and may impact our operations, including the potential interruption of our clinical trial activities 
and our supply chain, and the operations of our key business partners. Global health concerns, such as the recent developments 
around COVID-19, could also result in social, economic, and labor instability in the countries in which we or the third parties with 
whom we engage operate. We may also take temporary precautionary measures intended to help minimize the risk of COVID-19 
to our employees, including temporarily requiring our employees to work remotely, suspending non-essential travel worldwide for 
our employees and discouraging employee attendance at industry events and in-person work-related meetings. These measures 
could negatively affect our business. COVID-19 has also caused volatility in the global financial markets and threatened a slowdown 
in the global economy, which may negatively affect our ability to raise additional capital on attractive terms or at all. We cannot 
presently predict the scope and severity of any potential business shutdowns or disruptions, but if we or any of the third parties 
with whom we engage, including the suppliers, contract manufacturers, clinical trial sites, regulators and other third parties with 
whom we conduct business, were to experience shutdowns or other business disruptions, our ability to conduct our business in 
the manner and on the timelines presently planned could be materially and negatively impacted. 

For example, the spread of an infectious disease, including COVID-19, may result in the inability of our suppliers to deliver clinical 
drug supplies on a timely basis or at all. In addition, hospitals may reduce staffing and reduce or postpone certain treatments in 
response to the spread of an infectious disease. Such events may result in a period of business disruption, and in reduced oper-
ations, or doctors and medical providers may be unwilling to participate in our clinical trials, any of which could materially affect 
our business, financial condition and results of operations. It is also possible that global health concerns such as this one could 
disproportionately impact the clinical sites in which we conduct any of our clinical trials, which could have a material adverse effect 
on our business and our results of operation and financial condition.

22  |  Risk Factors Related to Our Business and Industry

The extent to which the recent global COVID-19 pandemic impacts our business will depend on future developments, which are 
highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19 and the 
actions to contain or treat its impact, among others. Any significant infectious disease outbreak, including the COVID-19 pandemic, 
could result in a widespread health crisis that could adversely affect the economies and financial markets worldwide, resulting in 
an economic downturn that could impact our business, financial condition and results of operations, including our ability to obtain 
additional funding, if needed. 

In addition, a catastrophic event that results in the destruction or disruption of our data centers or our critical business or infor-
mation technology systems would severely affect our ability to conduct normal business operations and, as a result, our operating 
results would be adversely affected.

1.4.8.  WE FACE THE RISK OF COMPU TER SYS TEM FAI LUR E S, DATA LEAK S AN D CYB ERCR I M ES.

Despite the implementation of security measures, our internal computer systems and those of our third-party service providers are 
vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and 
electrical failure. Cyber-attacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult 
to detect. Cyber-attacks could include the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering 
and other means to affect service reliability and threaten the confidentiality, integrity and availability of information. Cyber-attacks 
also could include phishing attempts or e-mail fraud to cause payments or information to be transmitted to an unintended recipient.

 Any system failure, accident or security breach that causes interruptions in our own or in third-party service vendors’ operations 
could result in a material disruption of our product development programs. For example, the loss of clinical trial data from completed 
or future clinical trials could result in delays in our or our partners’ regulatory approval efforts and significantly increase our costs 
in order to recover or reproduce the lost data. To the extent that any disruption or security breach results in a loss or damage to 
our data or applications, or inappropriate disclosure of confidential or proprietary information, we may incur liability, our product 
development programs and competitive position may be adversely affected and the further development of our product candidates 
may be delayed. If the integrity of our cybersecurity systems is breached, we may incur significant effects such as remediation 
expenses, lost revenues, litigation costs and increased insurance premiums and may also experience reputational damage and the 
erosion of shareholder value. Furthermore, we may incur additional costs to remedy the damage caused by these disruptions or 
security breaches. Like other companies, we have on occasion experienced, and will continue to experience, threats to our data 
and systems, including malicious codes and viruses, phishing, business email compromise attacks, or other cyber-attacks. Whereas 
none of these instances had a material impact so far, the number and complexity of these threats continue to increase over time. If 
a material breach of our information technology systems or those of our third party service providers occurs, the market perception 
of the effectiveness of our security measures could be harmed and our reputation and credibility could be damaged.

We could be required to expend significant amounts of money and other resources to respond to these threats or breaches and to 
repair or replace information systems or networks, and could suffer financial loss or the loss of valuable confidential information. 
In addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving 
privacy issues related to data collection and use practices and other data privacy laws and regulations, including claims for misuse 
or inappropriate disclosure of data, as well as unfair or deceptive practices. Although we develop and maintain systems and controls 
designed to prevent these events from occurring, and we have a process to identify and mitigate threats, the development and 
maintenance of these systems, controls and processes is costly and requires ongoing monitoring and updating as technologies 
change and efforts to overcome security measures become increasingly sophisticated. Moreover, despite our efforts, the possibility 
of these events occurring cannot be eliminated entirely and there can be no assurance that any measures we take will prevent 
cyber-attacks or security breaches that could adversely affect our business.

In order to successfully commercialize and market our products in the future we may need to implement additional enterprise 
resource management systems which is a complex process that may cause us to face delays. We may also need to implement 
computer systems such as additional global enterprise research systems, or ERP systems, in which we have limited experience and 
which may prove a complex process that could cause delays in our commercialization process.

We have relied upon and plan to continue to rely upon third parties, including independent clinical investigators and third-party 
CROs, to conduct our preclinical studies and clinical trials and to monitor and manage data for our ongoing preclinical and clinical 
programs. We rely on these parties for execution of our preclinical studies and clinical trials, and control only certain aspects of 
their activities. Nevertheless, we are responsible for ensuring that each of our studies and trials is conducted in accordance with 
the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on these third parties does 
not relieve us of our regulatory responsibilities. We and our third-party contractors and CROs are required to comply with GCP 
requirements, which are regulations and guidelines enforced by the FDA, the EMA, the PDMA and comparable foreign regulatory 
authorities for all of our products in clinical development. Regulatory authorities enforce these GCPs through periodic inspections 
of trial sponsors, principal investigators and trial sites. If we, our investigators or any of our CROs fail to comply with applicable 
GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the EMA, the PDMA or comparable 
foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. Upon 
inspection by a given regulatory authority, such regulatory authority may determine that our clinical trials do not fully comply with 
GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to 
comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. 

Further, these investigators and CROs are not our employees and we will not be able to control, other than by contract, the amount 
of resources, including time, which they devote to our product candidates and clinical trials. If independent investigators or CROs 
fail to devote sufficient resources to the development of our product candidates, or if their performance is substandard, it may 
delay or compromise the prospects for approval and commercialization of any product candidates that we develop. In addition, 
the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase 
the risk that this information will be misappropriated. 

Our CROs have the right to terminate their agreements with us in the event of an uncured material breach. In addition, some of 
our CROs have an ability to terminate their respective agreements with us if 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. 

There is a limited number of third-party service providers that specialize or have the expertise required to achieve our business 
objectives. If any of our relationships with these third-party CROs or clinical investigators terminate, we may not be able to enter 
into arrangements with alternative CROs or investigators or to do so on commercially reasonable terms. If CROs or clinical investi-
gators 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. As a result, our results of operations and the 
commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues 
could be delayed. 

Switching or adding additional CROs (or investigators) 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 similar 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 results of operations.

We are, and expect to continue to be, dependent on partnerships with partners relating to the development and commercialization 
of our existing and future research programs and product candidates. We currently have collaborative research relationships with 
various pharmaceutical companies such as Janssen, AbbVie, Shire and with various academic and research institutions worldwide, 
for the development of product candidates resulting from such collaborations. We had, have and will continue to have discussions 
on potential partnering opportunities with various pharmaceutical companies. If we fail to enter into or maintain collaborations on 
reasonable terms or at all, our ability to develop our existing or future research programs and product candidates could be delayed, 
the commercial potential of our products could change and our costs of development and commercialization could increase. 

Our dependence on collaborative partners subjects us to a number of risks, including, but not limited to termination of the 
collaboration agreements with all its consequences, disagreement on the interpretation of contractual terms or no adherence or 
uncertainties as part of the ongoing collaboration.

We face significant competition in seeking appropriate collaborative partners. Our ability to reach a definitive agreement for a 
partnership will depend, among other things, upon an assessment of the collaborator’s resources and expertise, the terms and 
conditions of the proposed partnership and the proposed collaborator’s evaluation of a number of factors. These factors may include 
the design or results of clinical trials, the likelihood of regulatory approval, the potential market for the subject product candidate, 
the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, 
the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership 
regardless of the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative 
product candidates or technologies for similar indications that may be available to collaborate on and whether such a partnership 
could be more attractive than the one with us.

We do not currently have, nor do we plan to acquire, the infrastructure or capability internally to manufacture our product candi-
dates for use in the conduct of our clinical studies or for commercial supply, if our products are approved. Instead, we rely on, and 
expect to continue to rely on contract manufacturing organizations, or CMOs. We currently rely mainly on Lonza Sales AG, or Lonza, 
based in Slough, UK and Singapore for the manufacturing of the drug substance of all our products and the production cell line 
POTELLIGENT® CHOK1SV jointly owned by Lonza and BioWa, Inc. for clinical and commercial scale production of ADCC enhanced 
antibody products. Reliance on third-party providers may expose us to more risk than if we were to manufacture our product 
candidates ourselves. We do not control the manufacturing processes of the CMOs we contract with and are dependent on those 
third parties for the production of our product candidates in accordance with relevant regulations (such as cGMP), which includes, 
among other things, quality control, quality assurance and the maintenance of records and documentation.

If we were to experience an unexpected loss of supply of or if any supplier were unable to meet our demand for any of our product 
candidates, we could experience delays in our research or planned clinical studies or commercialization. We could be unable to 
find alternative suppliers of acceptable quality, in the appropriate volumes and at an acceptable cost. Moreover, our suppliers are 
often subject to strict manufacturing requirements and rigorous testing requirements, which could limit or delay production. The 

Risk Factors Related to Our Dependence on Third Parties    |  25 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXRISK FACTORSlong transition periods necessary to switch manufacturers and suppliers, if necessary, would significantly delay our clinical studies 
and the commercialization of our products, if approved, which would materially adversely affect our business, financial condition 
and results of operation. 

We and our third-party suppliers may also be subject to audits by the FDA, the EMA, the PDMA or other comparable foreign 
authorities. If any of our third-party suppliers fails to comply with cGMP or other applicable manufacturing regulations, our ability 
to develop and commercialize the products could suffer significant interruptions. We face risks inherent in relying on a single CMO, 
as any disruption, such as a fire, natural hazards or vandalism at the CMO could significantly interrupt our manufacturing capability. 
Alternative production plans in place or disaster-recovery facilities available to us may not be sufficient. In case of a disruption, we 
may have to establish additional alternative manufacturing sources. This would require substantial capital on our part, which we 
may not be able to obtain on commercially acceptable terms or at all. Additionally, we may experience significant manufacturing 
delays as we build or locate replacement facilities and seek and obtain necessary regulatory approvals. If this occurs, we will be 
unable to satisfy manufacturing needs on a timely basis, if at all. Also, operating any new facilities may be more expensive than 
operating our current facilities. Further, business interruption insurance may not adequately compensate us for any losses that 
may occur, and we would have to bear the additional cost of any disruption. For these reasons, a significant disruptive event of the 
manufacturing facility could have drastic consequences, including placing our financial stability at risk.

The manufacturing of all of our product candidates requires using cells which are stored in a cell bank. We have one master cell bank 
for each product manufactured in accordance with cGMP. Working cell banks have not yet been manufactured. Half of each master 
cell bank is stored at a separate site so that in case of a catastrophic event at one site we believe sufficient vials of the master cell 
banks are left at the alternative storage site to continue manufacturing. We believe sufficient working cell banks could be produced 
from the vials of the master cell bank stored at a given site to assure product supply for the future. However, it is possible that we 
could lose multiple cell banks and have our manufacturing significantly impacted by the need to replace these cell banks, which 
could materially adversely affect our business, prospects, financial condition and results of operations.

We have collaborated, and plan to continue to collaborate, with third parties on product candidates that we believe have promising 
utility in disease areas or patient populations that are better served by resources of larger biopharmaceutical companies. See section 
3.6 “Material Contracts and Collaboration Agreements” on page 87 and further for a description of these collaborations. As part of 
some of these collaborations, our collaboration partners are responsible for providing us with financial information regarding specific 
projects, including funds spent, liabilities incurred and expected future costs, on which we rely for our own financial reporting. 
In the event that our collaboration partners fail to provide us with the necessary financial information within the agreed upon 
timeframes, or if such financial information proves partially inaccurate, this is likely to impact the accuracy of our own financial 
reporting. Our reliance on financial information received from our collaboration partners may impact our own internal and external 
financial reporting and any delay in the provision of such financial information to us or any failure by us to identify mistakes in the 
financial information provided to us may cause our own financial statements to be partially inaccurate. Any inaccuracy in our financial 
reporting could cause investors to lose confidence in our financial reporting. This in turn may lead to reputational damage and/or 
affect our ability to, and the terms on which we may, obtain future (equity) financing which may harm our business.

1.6.1.  WE RELY ON PAT ENTS AN D OT HE R I N T ELL ECT UAL PRO P ERT Y R I G H TS TO PROTECT OUR

THESE RIGHT S ADEQUAT ELY COU LD H AR M O UR AB I LI TY TO COM PE TE AN D I MPAI R OUR 
BUSINESS.

Our commercial success depends in part on obtaining and maintaining patents and other forms of intellectual property rights for 
our product candidates, methods used to manufacture those products and the methods for treating patients using those products, 
or on licensing in such rights. Failure to protect or to obtain, maintain or extend adequate patent and other intellectual property 
rights could materially adversely affect our ability to develop and market our products and product candidates. The enforcement, 
defense and maintenance of such patents and other intellectual property rights may be challenging and costly.

We cannot be certain that patents will be issued or granted with respect to applications that are currently pending. As a biophar-
maceutical company our patent position is uncertain because it involves complex legal and factual considerations. The standards 
applied by the European Patent Office, the United States Patent and Trademark Office, or USPTO, and foreign patent offices in 
granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding 
patentable subject matter or the scope of claims allowable in biopharmaceutical patents. Consequently, patents may not issue from 
our pending patent applications. As such, we do not know the degree of future protection that we will have on our proprietary 
products and technology. The scope of patent protection that the European Patent Office and the USPTO will grant with respect 
to the antibodies in our antibodies product pipeline is uncertain. It is possible that the European Patent Office and the USPTO will 
not allow broad antibody claims that cover antibodies closely related to our product candidates as well as the specific antibody. As 
a result, upon receipt of EMA or FDA approval, competitors may be free to market antibodies almost identical to ours, including 
biosimilar antibodies, thereby decreasing our market share. However, a competitor cannot submit to the FDA an application for 
a biosimilar product based on one of our products until four years following the date of approval of our “reference product,” and 
the FDA may not approve such a biosimilar product until 12 years from the date on which the reference product was approved. 
See paragraph 3.7.2 “Licensure and Regulation of Biologics in the United States” on page 97 and further for more details regarding 
biosimilar regulatory exclusivities. 

The patent prosecution process is expensive and time-consuming, and we and our current or future licensors, licensees or collab-
oration partners may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost 
or in a timely manner. It is also possible that we or our licensors, licensees or collaboration partners will fail to identify patentable 
aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent 
protection on them. Further, the issuance, scope, validity, enforceability and commercial value of our and our current or future 
licensors’, licensees’ or collaboration partners’ patent rights are highly uncertain. Our and our licensors’ pending and future patent 
applications may not result in patents being issued that protect our technology or products, in whole or in part, or that effectively 
prevent others from commercializing competitive technologies and products. Moreover, in some circumstances, we may not have 
the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, or we may need to 
enter into new license or royalty agreements, covering technology that we license from or license to third parties or have developed 
in collaboration with our collaboration partners and are reliant on patent procurement activities of our licensors, licensees or 
collaboration partners. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with 
the best interests of our business. If our current or future licensors, licensees or collaboration partners fail to establish, maintain 
or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors, licensees 
or collaboration partners are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any 
patent rights, such patent rights could be compromised. The patent examination process may require us or our licensors, licensees 
or collaboration partners to narrow the scope of the claims of our or our licensors’, licensees’ or collaboration partners’ pending 
and future patent applications, which may limit the scope of patent protection that may be obtained. We cannot assure you that 
all of the potentially relevant prior art relating to our patents and patent applications has been found. If such prior art exists, it can 
invalidate a patent or prevent a patent from issuing from a pending patent application. Even if patents do successfully issue and 
even if such patents cover our product candidates, third parties may initiate an opposition, interference, re-examination, post-grant 
review, inter partes review, nullification or derivation action in court or before patent offices, or similar proceedings challenging 
the validity, enforceability or scope of such patents, which may result in the patent claims being narrowed or invalidated. Our

and our licensors’, licensees’ or collaboration partners’ patent applications cannot be enforced against third parties practicing the 
technology claimed in such applications unless and until a patent issues from such applications, and then only to the extent the 
issued claims cover the technology.

Because patent applications are confidential for a period of time after filing, and some remain so until issued, we cannot be certain 
that we or our licensors were the first to file any patent application related to a product candidate. Furthermore, as to the United 
States, if third parties have filed such patent applications on or before March 15, 2013, an interference proceeding can be initiated by 
such third parties to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. 
If third parties have filed such applications after March 15, 2013, a derivation proceeding can be initiated by such third parties to 
determine whether our invention was derived from theirs. Even where we have a valid and enforceable patent, we may not be able 
to exclude others from practicing our invention where the other party can show that they used the invention in commerce before 
our filing date, or if the other party is able to obtain a compulsory license. Any of the aforementioned situations could cause harm 
to our ability to protect our intellectual property, which in turn would allow competitors to market comparable products which 
could materially adversely affect our competitive position and as such our business, financial condition and results of operation.

1.6.2.  ISSUED PATENTS COULD BE FO U N D I N VALI D O R UN E N FO RCE ABL E I F CHALL EN G E D I N CO URT.

To protect our competitive position, we may from time to time need to resort to litigation in order to enforce or defend any patents 
or other intellectual property rights owned by or licensed to us, or to determine or challenge the scope or validity of patents or other 
intellectual property rights of third parties. Enforcement of intellectual property rights is difficult, unpredictable and expensive, 
and many of our or our licensors’ or collaboration partners’ adversaries in these proceedings may have the ability to dedicate 
substantially greater resources to prosecuting these legal actions than we or our licensors or collaboration partners can. Accordingly, 
despite our or our licensors’ or collaboration partners’ efforts, we or our licensors or collaboration partners may not prevent third 
parties from infringing upon or misappropriating intellectual property rights we own or control, particularly in countries where the 
laws may not protect those rights as fully as in the European Union and the United States. We may fail in enforcing our rights—in 
which case our competitors may be permitted to use our technology without being required to pay us any license fees. In addition, 
however, litigation involving our patents carries the risk that one or more of our patents will be held invalid (in whole or in part, on a 
claim-by-claim basis) or held unenforceable. Such an adverse court ruling could allow third parties to commercialize our products or 
use our SIMPLE AntibodyTM, NHance® and ABDEGTM platform technologies, and then compete directly with us, without payment to us. 

If we were to initiate legal proceedings against a third party to enforce a patent covering one of our products, the defendant 
could counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States or in Europe, defendant 
counterclaims alleging invalidity or unenforceability are commonplace. A claim for a validity challenge may be based on failure to 
meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. A claim for unenforce-
ability could involve an allegation that someone connected with prosecution of the patent withheld relevant information from the 
European Patent Office or the USPTO or made a misleading statement, during prosecution. The outcome following legal assertions 
of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we 
cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. 
If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of 
the patent protection on one or more of our products or certain aspects of our SIMPLE AntibodyTM, NHance® and ABDEGTM platform 
technologies. Such a loss of patent protection could have a material adverse impact on our business. Further, litigation could result 
in substantial costs and diversion of management resources, regardless of the outcome, and this could harm our business and 
financial results. Patents and other intellectual property rights also will not protect our technology if competitors design around 
our protected technology without infringing our patents or other intellectual property rights.

POSITION.

Our competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover our 
products or elements thereof, our manufacture or uses relevant to our development plans, the targets of our product candidates, 
or other attributes of our product candidates or our technology. In such cases, we may not be in a position to develop or commer-
cialize products or product candidates unless we successfully pursue litigation to nullify or invalidate the third-party intellectual 
property right concerned, or enter into a license agreement with the intellectual property right holder, if available on commercially 
reasonable terms. We are aware of certain U.S. issued patents held by third parties that some may argue cover certain aspects of 
our product candidates, including cusatuzumab and ARGX-111. The patent relating to cusatuzumab is scheduled to expire in 2026, 
and the patents relating to ARGX-111 are scheduled to expire between 2024 and 2032. In the event that a patent has not expired 
at the time of approval of such product candidate and the patent owner were to bring an infringement action against us, we may 
have to argue that our product, its manufacture or use does not infringe a valid claim of the patent in question. Alternatively, if we 
were to challenge the validity of any issued U.S. patent in court, we would need to overcome a statutory presumption of validity 
that attaches to every U.S. patent. This means that in order to prevail, we would need to present clear and convincing evidence 
as to the invalidity of the patent’s claims. There is no assurance that a court would find in our favor on questions of infringement 
or validity. In the event that a patent is successfully asserted against us such that the patent is found to be valid and enforceable 
and infringed by our product, unless we obtain a license to such a patent, which may not be available on commercially reasonable 
terms or at all, we could be prevented from continuing to develop or commercialize our product. Similarly, the targets for certain 
of our product candidates have also been the subject of research by other companies, which have filed patent applications or have 
patents on aspects of the targets or their uses. There can be no assurance any such patents will not be asserted against us or that 
we will not need to seek licenses from such third parties. We may not be able to secure such licenses on acceptable terms, if at all, 
and any such litigation would be costly and time-consuming. 

It is also possible that we failed to identify relevant patents or applications. For example, certain U.S. applications filed after 
November 29, 2000 that will not be filed outside the United States may remain confidential until patents issue. In general, patent 
applications in the United States and elsewhere are published approximately 18 months after the earliest filing from which priority 
is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering 
our products or platform technology could have been filed by others without our knowledge. Furthermore, we operate in a highly 
competitive field, and given our limited resources, it is unreasonable to monitor all patent applications purporting to gain broad 
coverage in the areas in which we are active. Additionally, pending patent applications which have been published can, subject 
to certain limitations, be later amended in a manner that could cover our platform technologies, our products or the use of our 
products. 

Third-party intellectual property right holders, including our competitors, may actively bring infringement claims against us. The 
granting of orphan drug status in respect of any of our product candidates does not guarantee our freedom to operate and is 
separate from our risk of possible infringement of third parties’ intellectual property rights. We may not be able to successfully 
settle or otherwise resolve such infringement claims. If we are unable to successfully settle future claims on terms acceptable to 
us, we may be required to engage or continue costly, unpredictable and time-consuming litigation and may be prevented from or 
experience substantial delays in marketing our products. 

If we fail in any such dispute, in addition to being forced to pay damages, we or our licensees may be temporarily or permanently 
prohibited from commercializing any of our product candidates that are held to be infringing. We might, if possible, also be forced 
to redesign product candidates so that we no longer infringe the third-party intellectual property rights. Or, we may be required to 
seek a license to any such technology that we are found to infringe, which license may not be available on commercially reasonable 
terms, or at all. Even if we or our licensors or collaboration partners obtain a license, it may be non-exclusive (for example, the 
POTELLIGENT® platform), thereby giving our competitors access to the same technologies licensed to us or our licensors or collab-
oration partners. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we 
are found to have willfully infringed a patent. Any of these events, even if we were to ultimately prevail, could require us to divert 
substantial financial and management resources that we would otherwise be able to devote to our business. 

30  |  Risk Factors Related to Intellectual Property

In addition, if the breadth or strength of protection provided by our or our licensors’ or collaboration partners’ patents and patent 
applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or 
future product candidates. 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. 

We may be required to defend against claims of intellectual property infringement that may be asserted by our competitors against 
us and, if the outcome of any such litigation is adverse to us, it may affect our ability to compete effectively. 

Our involvement in litigation, and in, e.g., any interference, derivation, reexamination, inter partes review, opposition or post-grant 
proceedings or other intellectual property proceedings inside and outside of the European Union or the United States may divert 
management time from focusing on business operations, could cause us to spend significant amounts of money and may have no 
guarantee of success.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur 
significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition, 
there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if 
securities analysts or investors perceive these results to be negative, this may negatively impact us. Such litigation or proceedings 
could substantially increase our operating losses and reduce our resources available for development activities. We may not have 
sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able 
to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial 
resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material 
adverse effect on our ability to compete in the marketplace. 

Many of our consultants and employees, including our senior management, were previously employed at other biotechnology or 
pharmaceutical companies, including our competitors or potential competitors. Some of these consultants and employees executed 
proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try 
to ensure that our consultants and employees do not use the proprietary information or know-how of others in their work for us, we 
may be subject to claims that we or these consultants and employees have used or disclosed confidential information or intellectual 
property, including trade secrets or other proprietary information, of any such consultant’s or employee’s former employer, or have 
breached their non-competition agreement. Litigation may be necessary to defend against these claims. 

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual 
property rights or personnel or sustain damages. Such intellectual property rights could be awarded to a third party, and we could be 
required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available 
on commercially reasonable terms or at all. Even if we successfully prosecute or defend against such claims, litigation could result 
in substantial costs and distract management.

Because our programs may require the use of proprietary rights held by third parties, the growth of our business will likely depend 
in part on our ability to acquire, in-license, maintain or use these proprietary rights. We may be unable to acquire or in-license any 
compositions, methods of use, processes, or other third-party intellectual property rights from third parties that we identify as 
necessary for our product candidates. The licensing and acquisition of third-party intellectual property rights is a competitive area, 
and a number of more established companies may pursue strategies to license or acquire third-party intellectual property rights 
that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash 
resources and greater clinical development and commercialization capabilities.

development under written agreements with these institutions. Typically, these institutions provide us with an option to negotiate 
a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such option, we may be 
unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, 
the institution may offer the intellectual property rights to other parties, potentially blocking our ability to pursue our applicable 
product candidate or program. 

In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable 
to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our 
investment. If we are unable to successfully obtain a license to third-party intellectual property rights necessary for the development 
of a product candidate or program, we may have to abandon development of that product candidate or program and our business 
and financial condition could suffer.

We are a party to license agreements under which we are granted rights to intellectual property that are important to our business 
and we expect that we may need to enter into additional license agreements in the future. Existing license agreements impose, 
and we expect that future license agreements will impose, various development obligations, payment of royalties and fees based 
on achieving certain milestones, as well as other obligations. If we fail to comply with our obligations under these agreements, the 
licensor may have the right to terminate the license. The termination of any license agreements or failure to adequately protect 
such license agreements could prevent us from commercializing product candidates covered by the licensed intellectual property. 
Several of our existing license agreements are sublicenses from third parties which are not the original licensor of the intellectual 
property at issue. Under these agreements, we must rely on our licensor to comply with its obligations under the primary license 
agreements under which such third party obtained rights in the applicable intellectual property, where we may have no relationship 
with the original licensor of such rights. If the licensors fail to comply with their obligations under these upstream license agree-
ments, the original third-party licensor may have the right to terminate the original license, which may terminate the sublicense. 
If this were to occur, we would no longer have rights to the applicable intellectual property and, in the case of a sublicense, if we 
were not able to secure our own direct license with the owner of the relevant rights, which it may not be able to do at a reasonable 
cost or on reasonable terms, it may adversely affect our ability to continue to develop and commercialize the product candidates 
incorporating the relevant intellectual property.

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 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 ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and 
us and our partners; and 
the priority of invention of patented technology.

• 

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrange-
ments on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

we need to build name recognition by potential partners or customers in our markets of interest. Over the long term, if we are 
unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively

Patents have a limited duration. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is 
generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and 
the protection it affords, is limited. Even if patents covering our product candidates, their manufacture, or use are obtained, once 
the patent life has expired, we may be open to competition from competitive medications, including biosimilar medications. Given 
the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting 
such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent 
portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. 

Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. 
patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 
1984, referred to as the Hatch-Waxman Act and similar legislation in the European Union. The Hatch-Waxman Act permits a patent 
term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during 
product development and the FDA regulatory review process. The patent term extension cannot extend the remaining term of a 
patent beyond a total of 14 years from the date of product approval, and only one patent applicable to an approved drug may be 
extended. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration 
of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than 
we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period 
during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market 
competing products sooner than we expect. As a result, our revenue from applicable products could be reduced, possibly materially.

We often file our first patent application (i.e., priority filing) at the UK Intellectual Property Office, the European Patent Office or 
the USPTO. International applications under the Patent Cooperation Treaty, or PCT, are usually filed within twelve months after 
the priority filing. Based on the PCT filing, national and regional patent applications may be filed in additional jurisdictions where 
we believe our product candidates may be marketed. We have so far not filed for patent protection in all national and regional 
jurisdictions where such protection may be available. In addition, we may decide to abandon national and regional patent appli-
cations before grant. Finally, the grant proceeding of each national/regional patent is an independent proceeding which may lead 
to situations in which applications might in some jurisdictions be refused by the relevant patent offices, while granted by others. 
It is also quite common that depending on the country, the scope of patent protection may vary for the same product candidate 
or technology.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXRISK FACTORSCompetitors may use our and our licensors’ or collaboration partners’ 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 and 
our licensors or collaboration partners have patent protection, but enforcement is not as strong as that in the United States and the 
European Union. These products may compete with our product candidates, and our and our licensors’ or collaboration partners’ 
patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. 

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and 
the European Union, and companies have encountered significant difficulties in protecting and defending such rights in such 
jurisdictions. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the 
intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished and we 
may face additional competition from others in those jurisdictions. 

Some countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. 
In addition, some 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, results of operations and financial condition may be adversely affected. 

Proceedings to enforce our and our licensors’ or collaboration partners’ patent rights in foreign jurisdictions could result in substan-
tial costs and divert our and our licensors’ or collaboration partners’ efforts and attention from other aspects of our business, could 
put our and our licensors’ or collaboration partners’ patents at risk of being invalidated or interpreted narrowly and our and our 
licensors’ or collaboration partners’ patent applications at risk of not issuing and could provoke third parties to assert claims against 
us or our licensors or collaboration partners. We or our licensors or collaboration partners may not prevail in any lawsuits that we 
or our licensors or collaboration partners initiate and the damages or other remedies awarded, if any, may not be commercially 
meaningful.

The America Invents Act, or the AIA, has been enacted in the United States, resulting in significant changes to the U.S. patent 
system. An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” 
system for deciding which party should be granted a patent when two or more patent applications are filed by different parties 
claiming the same invention. A third party that files a patent application in the USPTO after that date but before us could therefore 
be awarded a patent covering an invention of ours even if we had made the invention before it was made by the third party. This 
will require us to be cognizant going forward of the time from invention to filing of a patent application, but circumstances could 
prevent us from promptly filing patent applications on our inventions. 

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit 
and providing opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even 
those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary 
standard in U.S. federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO 
proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the 
claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate 
our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. 
The AIA 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. 

34  |  Risk Factors Related to Intellectual Property

Additionally, 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. In addition to increasing 
uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect 
to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws 
and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to 
enforce our existing patents and patents that we might obtain in the future. 

Any inability of us to protect our competitive advantage with regard to any of our product candidates may prevent us from success-
fully monetizing such product candidate and this could materially adversely affect our business, prospects, financial condition and 
results of operations.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO, the European Patent Office and foreign 
patent agencies in several stages over the lifetime of the patent. The USPTO, the European Patent Office and various foreign govern-
mental 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 noncompliance can result in abandonment or lapse of 
the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance 
events that could result in abandonment or lapse of a patent or patent application include 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 or 
collaboration partners fail to maintain the patents and patent applications covering our product candidates, our competitors might 
be able to enter the market, which would have an adverse effect on our business.

Our success depends upon the continued contributions of our key management, scientific and technical personnel, many of whom 
have been instrumental for us and have substantial experience with our therapies and related technologies. These key management 
individuals include the members of our board of directors and executive management, as described in detail in section 6.2.3 “Our 
Executive Management “ on page 150 and further.

The loss of key managers and senior scientists could delay our research and development activities. In addition, our ability to 
compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract and retain highly 
qualified management, scientific and medical personnel. Many other biotechnology and pharmaceutical companies and academic 
institutions that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a 
longer history in the industry than we do. Therefore, we might not be able to attract or retain these key persons on conditions that 
are economically acceptable. Furthermore, we will need to recruit new managers and qualified scientific, commercial, regulatory 
and financial personnel to develop our business if we expand into fields that will require additional skills. Our inability to attract 
and retain these key persons could prevent us from achieving our objectives and implementing our business strategy, which could 
have a material adverse effect on our business and prospects.

We have grown significantly in number of employees and scope of operations over the recent years and expect to experience 
significant growth in the number of our employees and the scope of our operations also in the near future, particularly in the areas 
of drug development, regulatory affairs and sales and marketing. To manage our anticipated future growth, we must continue to 
implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train 
additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in 
managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or 
recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our 
management and business development resources. Any inability to manage growth could delay the execution of our business plans 
or disrupt our operations, which in turn could materially harm our business and prospects.

1.7.3.  WE HAVE OBTAINED S IGNIFICAN T FU N DI N G FROM AGE N CI E S OF THE G OV E R N M EN T OF 

THE FLEMISH REGION OF BELGI U M AN D H AV E BE N EF I TE D FRO M CE RTAI N R ES E ARCH AND 
DEVELOPMENT IN CENTIV ES. THE TAX AUT H OR I TI E S MAY CHALL EN G E O UR E LI G I B I LI TY FO R 
OR O UR CALCULAT ION OF SUCH I N C EN T I VES.

We have contracted over the past years numerous funding agreements with agencies of the Flemish government to partially 
finance our research and development programs. These funding agreements are subject to various criteria linked to employment 
and investment in the Flemish region of Belgium. We have committed to establish our operational site in the Flemish region, which 
must remain our major effective operational site, and to maintain our site and all our existing activities, including research and 
development in the Flemish region. Similarly, our funding agreement with one such agency of the Flemish government requires us 
to maintain substantial research and development activities in the Flemish region. Such undertakings restrict our ability to choose 
the most convenient or cost-effective location of our premises. 

If we were to breach these contractual obligations, we may be held liable by the agencies of the Flemish government with which 
we have funding agreements for any damage incurred by the such agencies resulting from the breach of contract and we could be 
required to reimburse in full the subsidies granted by such agencies. 

Further, pursuant to the general terms of each grant, certain Flemish agencies are entitled to re-evaluate the subsidies granted 
to us in case of a fundamental change in our shareholding base, which is not defined in the general terms, but we believe would 
involve a change of control of us. Any such reevaluation could negatively impact the funding that we receive or have received from 
the Flemish agencies. 

The research and development incentives from which we have benefited as a company active in research and development in 
Belgium can be offset against Belgian corporate income tax due. The excess portion may be refunded at the end of a five-year 
fiscal period for the Belgian research and development incentive. The research and development incentives are both calculated 
based on the amount of eligible research and development expenditure. The Belgian tax authorities may audit each research and 
development program in respect of which a tax credit has been claimed and assess whether it qualifies for the tax credit regime. 
The tax authorities may challenge our eligibility for, or our calculation of, certain tax reductions or deductions in respect of our 
research and development activities and, should such a claim of the Belgian tax administration be successful, we may be liable for 
additional corporate income tax, and penalties and interest related thereto, which could have a significant impact on our results of 
operations and future cash flows. Furthermore, if the Belgian government decide to eliminate, or reduce the scope or the rate of, 
the research and development incentive benefit, either of which it could decide to do at any time, our results of operations could 
be adversely affected.

MATERIALLY AF FEC T OUR RESU LTS O F O P ER AT I ON S AN D F I N AN CI AL CON DI T I ON.

Due to the international scope of our operations, our assets, earnings and cash flows are influenced by movements in exchange 
rates of several currencies, particularly the U.S. dollar, British pound and Swiss francs. Our functional currency is the euro and the 
majority of our operating expenses are paid in euros, but we also receive payments from our main business partners Janssen, 
AbbVie and Shire in U.S. dollars and we regularly acquire services, consumables and materials in U.S. dollars, Swiss francs and 
British pounds. Further, potential future revenue may be derived from abroad, particularly from the United States. As a result, our 
business and share price may be affected by fluctuations in foreign exchange rates between the euro and these other currencies, 
which may also have a significant impact on our reported results of operations and cash flows from period to period. Currently, we 
do not have any exchange rate hedging arrangements in place.

1.7.5.  WE ARE EXPOSED TO UNANTICI PATED CH AN GE S I N TAX LAW S AN D R EG ULAT I ON S, 

ADJUSTMENTS TO OUR TAX PROVI S I O N S, EXP O S UR E TO ADD I TI O N AL TAX L I AB I LI TI E S, OR 
FORFEITURE OF OUR TAX ASSETS.

The determination of our provision for income taxes and other tax liabilities requires significant judgment, including the adoption of 
certain accounting policies and our determination of whether our deferred tax assets are, and will remain, tax effective. We cannot 
guarantee that our interpretation or structure will not be questioned by the relevant tax authorities, or that the relevant tax laws 
and regulations, or the interpretation thereof, including through tax rulings, by the relevant tax authorities, will not be subject to 
change. Any adverse outcome of such a review may lead to adjustments in the amounts recorded in our financial statements and 
could have a materially adverse effect on our operating results and financial condition. 

We are subject to laws and regulations on tax levies and other charges or contributions in different countries, including transfer 
pricing and tax regulations for the compensation of personnel and third parties. Dealings between current and former group 
companies as well as additional companies that may form part of our group in the future are subject to transfer pricing regulations, 
which may be subject to change and could affect us. 

Our effective tax rates could be adversely affected by changes in tax laws, treaties and regulations, both internationally and domes-
tically, or the interpretation thereof by the relevant tax authorities, including changes to the patent income deduction, possible 
changes to the corporate income tax base, wage withholding tax incentive for qualified research and development personnel in 
Belgium and other tax incentives and the implementation of new tax incentives such as the innovation deduction. An increase of 
the effective tax rates could have an adverse effect on our business, financial position, results of operations and cash flows. 

In addition, we may not be able to use, or changes in tax regulations may affect the use of, certain tax assets or credits that we 
have built over the years. For instance, as of December 31, 2019, we had €160.0 million of consolidated tax loss carry forwards. In 
general, some of these tax losses carry forwards may be forfeited in whole, or in part, as a result of various transactions, or their 
utilization may be restricted by statutory law in the relevant jurisdiction. Any corporate reorganization by us or any transaction 
relating to our shareholding structure may result in partial or complete forfeiture of tax loss carry forwards. For instance, under 
Belgian law, argenx BV may lose its tax loss carry forwards in case of a change of control, through an acquisition or otherwise, not 
meeting legitimate financial or economic needs as well as in case of a tax neutral reorganization, such as a merger or a demerger, 
involving argenx BV. The tax burden would increase if profits, if any, could not be offset against tax loss carry forwards.

2.1.  Message from the CEO 

and the chairman of our Board of Directors

Dear Shareowners,

Through our argenx 2021 vision, we are establishing 
ourselves as an integrated biotechnology company in 
time for our first product launch in 2021. During the 
past year, we transformed into a late-stage clinical 
development company ready to run 5 registrational 
and 7 earlier-stage clinical trials. This momentum fuels 
our ambition to have 5 product launches in 5 years 
starting in 2021. To succeed in our argenx 2021 vision, 
we know we have to play to win.

At our R&D Day last year, we announced the first 2 
commercial franchises where we will play. These 
include a neuromuscular franchise focused on rare 
autoimmune diseases like myasthenia gravis and 
chronic inflammatory demyelinating polyneuropathy, 
and a hematology/oncology franchise focused on rare 
autoimmune diseases like immune thrombocytopenia 
and blood cancers like acute myeloid leukemia and 
high-risk myelodysplastic syndromes. 

Innovation is our core business and defines our 
winning strategy every step of the way from discovery 
to development to commercialization. Our innovation 
relies heavily on partnership and leveraging each 
other’s strengths. We build differentiated, first-in-
class molecules through partnerships with some of 
the world’s best target biologists. We also partner 

closely with patients and physicians in how we build 
thoughtful clinical trials, and how we approach our 
understanding of the myasthenia gravis market 
through unique real-world evidence initiatives like 
MyRealWorld™ MG. 

argenx  refers  to  the  ancient  Greek  myth  of  the 
argonauts, the first story known to man talking 
about the collective power of the team rather than 
individual heroes. We take this collaborative spirit 
and wisdom into our daily work and together our 
internal teams continue to raise our ambition level 
and drive us towards success. We are very grateful 
to our colleagues in Tokyo, Ghent and Boston who 
stand shoulder-to-shoulder every day allowing us to 
confidently enter 2020. 

2020 will be the year where we read out our first 
Phase 3 registrational trial for efgartigimod. We know 
the myasthenia gravis patients are waiting for us and 
it is this resilience that provides us with our guiding 
purpose.

Thank you,

Tim Van Hauwermeiren  
& Peter Verhaeghe

2.2.1.  OPERATIONAL HIGHLIGHTS

argenx continued to execute on its plan to become a fully integrated immunology company through its “argenx 2021” vision, 
including building two commercial franchises in neuromuscular indications and hematology/oncology, with the potential to expand 
to include a third commercial franchise focused on skin/kidney indications.

Neuromuscular franchise

Efgartigimod (ARGX-113)

Completed enrolment ahead of the schedule of 167 gMG 
patients in registrational Phase 3 ADAPT trial with 10mg/
kg IV efgartigimod.

Initiated  and  successfully  completed  Phase 
1  healthy  volunteer  trial  of  SC  ENHANZE TM-
efgartigimod evaluating safety, pharmacokinetics, 
pharmacodynamics and bioavailability.

Phase 2 trial results in generalized 
myasthenia gravis (gMG) published 
in peer-reviewed journal, Neurology, 
further increasing awareness on the 
unique properties of efgartigimod 
and its potential in gMG. Data show 
that by reducing pathogenic auto-
antibodies, efgartigimod induces a 
rapid and sustained clinical activity 
in a tolerable way.

Initiated proof-of-concept Phase 2 ADHERE 
trial evaluating efficacy and safety of SC 
ENHANZE®-efgartigimod in approximately 
130 patients with active chronic inflamma-
tory demyelinating poly-neuropathy (CIDP). 
ADHERE will include an open-label stage 
A part of up to 12 weeks, followed by a 
placebo-controlled part, enrolling Stage A 
responders only, for treatment of up to 48 
weeks. The trail will be followed by an open 
label extension study.

Expanded pipeline with new therapeutic candidate ARGX-117, a complement-tar-
geting antibody against C2 with potential therapeutic applications in multiple autoim-
mune diseases. First-in-human clinical study is expected to start in first quarter 2020.

ARGX-117

42  |  2019 in brief

Hematology franchise

Efgartigimod (ARGX-113)

Cusatuzumab (ARGX-110)

Received orphan drug designation 
for efgartigimod in immune throm-
bocytopenia (ITP) from the European 
Medicines Agency (EMA) and the U.S. 
Food and Drug Administration (FDA).

As part of its exclusive, global collaboration and license 
agreement with Janssen, initiated registration directed 
Phase 2 CULMINATE trial in up to 150 newly diagnosed 
“unfit” AML patients who are not eligible for intensive 
chemotherapy. In this two-part trial, patients are first 
randomized to receive one of the two dose levels of 
cusatuzumab (10mg/kg and 20mg/kg) in combination 
with azacytidine (75mg/m2) followed by an expan-
sion cohort to evaluate safety of the selected dose of 
cusatuzumab.

Initiated registrational Phase 3 ADVANCE 
trial evaluating 10mg/kg IV efgartigimod for 
both induction and maintenance of platelet 
response in approximately 150 primary ITP 
patients with platelet counts ≤30x109/L. 
ADVANCE is the first of three registrational 
studies of the Phase 3 program with efgar-
tigimod in ITP.

Peer-reviewed publication of Phase 2 trial results in ITP 
in the American Journal of Hematology, further building 
awareness on the novel approach of efgartigimod as a new 
treatment modality in ITP. Data show that efgartigimod 
was well-tolerated and showed a correlation of reduced 
IgG levels, increased platelet counts and reduced bleeding 
events in ITP patients.

Presented preclinical data at the 
American Society of Hematology 
(ASH) Annual Meeting, high-lighting 
the  multiple  modes  of  action  of 
cusatuzumab  to  target  leukemic 
cells and the potential synergies of 
cusatuzumab in combination with 
venetoclax.

Initiated enrolment in cohort 3 of the adaptive Phase 2 
trial evaluating the efficacy of 10mg/kg IV or 25mg/kg IV 
efgartigimod in patients with pemphigus vulgaris (PV), 
aimed at establishing the optimal dosing regimen.

Preclinical program

Expanded pipeline with the addition of ARGX-118, an immunology breakthrough in 
airway inflammation, through its Innovative Access Program in partnership with VIB 
Inflammation Research Center, Ghent. ARGX-118 is a highly differentiated antibody 
against Galectin-10, the protein of Charcot-Leyden Crystals (CCLs), which play a major 
role in severe asthma and the persistence of mucus plugs.

Collaborations

Entered an exclusive global collaboration 
and license agreement with Cilag GmbH 
International, an affiliate of Janssen, for 
cusatuzumab where Janssen paid $300 
million  upfront  in  February  2019  and 
Johnson & Johnson Innovation Inc made an 
equity investment in the amount of €176.7 
million (approximately $200.0 million based 
on the exchange rate in effect as of the date 
the agreement with Janssen was signed) in 
our company resulting in a shareholding 
representing 4.68% of our outstanding share 
capital at the time of signing the agreement.

Received clinical milestone payment 
of $30 million from AbbVie related to 
the start of a first-in-human clinical 
trial for ABBV-151 (formerly known 
as ARGX-115), which is exclusively 
licensed to AbbVie. ABBV-115 is a 
fully human antibody that specif-
ically binds GARP, glycoprotein A 
repetitions predominant protein, a 
novel immuno-oncology target.

Entered into a global collaboration and license agreement 
with Halozyme under which we have been granted exclu-
sive access to Halozyme’s ENHANZE® drug delivery tech-
nology to develop multiple subcutaneous formulations 
for any product targeting FcRn, including efgartigimod, 
for the second therapeutic target C2 associated with the 
product candidate ARGX-117, and one additional target. 
The ENHANZE® technology could potentially shorten 
drug administration time, reduce healthcare practitioner 
time and offer additional flexibility and convenience for 
patients. Under the terms of the agreement, we paid an 
upfront fee of $30 million and will pay $10 million per 
target for future target nominations plus potential future 
payments of up to $160 million per selected target subject 
to achievement of specified development, regulatory 
and sales-based milestones. Halozyme is also eligible to 
receive mid-single royalties on sales of commercialized 
products.

Received development milestone payment of $25 million 
under the Janssen collaboration for the achievement of 
a certain enrolment threshold in the dose-confirming 
registration directed Phase 2 CULMINATE trial of cusatu-
zumab (ARGX-110) in combination with azacytidine for the 
treatment of newly diagnosed elderly patients with acute 
myeloid leukemia (AML) who are unfit for chemotherapy.

We continue to execute on our “argenx 2021” business plan to become a fully integrated immunology company and to bring much 
needed first-in-class medicines to patients suffering from severe diseases with our first launch of efgartigimod in gMG expected in 
2021. We continue to build our two initial commercial franchises in neuromuscular indications and hematology/oncology, with the 
potential to expand to include a third commercial franchise focused on skin/kidney indications. 

With efgartigimod, we continue to build our leadership position in FcRn and expect to run up to five registrational trials across four 
targeted indications (gMG, ITP, CIDP and PV), and to further evaluate its unique potential with the expansion into a fifth indication. In 
addition, we look forward to further expanding our global development for cusatuzumab in hematooncology with our collaboration 
partner Janssen.

In 2020, we anticipate the following late-stage pipeline milestones:

3.1.1.  OVERVIEW

We are a clinical-stage biotechnology company developing a deep pipeline of differentiated antibody-based therapies for the 
treatment of severe autoimmune diseases and cancer. Utilizing our suite of antibody technologies and through our Innovative Access 
Program (IAP) to explore novel disease biology, we are focused on developing product candidates with the potential to be either 
first-in-class against novel targets or best-in-class against known, but complex, targets in order to treat diseases with a significant 
unmet medical need. Through our “argenx 2021” vision we are on track to becoming a global, fully integrated novel immunology 
company with the potential launch of our first product, efgartigimod, in the United States in 2021.

Our SIMPLE Antibody™ Platform, based on the powerful llama immune system, together with the powerful IAP allows us to exploit 
novel and complex targets, and our three antibody Fc engineering technologies are designed to enable us to expand the therapeutic 
index of our product candidates. Together with our antibody discovery and development expertise, this suite of technologies has 
enabled us to build our broad pipeline of product candidates in severe autoimmune diseases and oncology, across all stages of 
development. Two of our product candidates are in potential registrational trials in three indications, one is being prepared to enter 
Phase 3 development in two additional indications, and three product candidates are in earlier stage development.

In September 2018, we launched our first Phase 3 trial, the ADAPT trial, for intravenous (IV) efgartigimod (ARGX-113), our most 
advanced product candidate targeting FcRn for the treatment of the rare neurological autoimmune disease myasthenia gravis, or 
MG. The full data from the Phase 2 trial in myasthenia gravis were reported in April 2018 and were published in the peer-reviewed 
journal, Neurology, in 2019. Completion of recruitment for the Phase 3 ADAPT trial was announced at the end of 2019 and topline 
data are expected mid-2020.

Also, in 2018 we successfully completed the Phase 2 clinical trial for efgartigimod in immune thrombocytopenia, or ITP, a rare 
hematological autoimmune disorder, and reported for the second time a proof-of-concept for our lead product candidate with 
strong clinical improvement over placebo. These Phase 2 trial results have been published in the peer-reviewed journal Hematology 
in December 2019. The first of two potential registrational Phase 3 trials of IV efgartigimod in ITP, the ADVANCE trial, was initiated 
in the fourth quarter of 2019.

In both Phase 2 studies in MG and ITP, efgartigimod was observed to have a favorable tolerability profile consistent with that 
observed in our Phase 1 clinical trial.

In September 2017, we initiated a Phase 2 clinical trial of efgartigimod for the treatment of a third indication, pemphigus vulgaris, or 
PV, a rare autoimmune blistering (skin) disease. In January 2020, we reported interim data of this Phase 2 proof-of-concept clinical 
trial where rapid disease control and clinical remission was observed with a favorable tolerability profile. 

These first indications and clinical development programs of efgartigimod were based on intravenous (IV) formulated efgartigimod. 
However, we are also developing a subcutaneous (SC) product formulation designed to enable administration potentially outside 
the hospital setting. In June 2018, we reported that at the same dose level the SC formulation was comparable across key measures, 
including half-life, pharmacodynamics (PD) and tolerability, to the IV formulation used in clinical studies to date. In July 2019, we 
also evaluated a standalone SC formulation of efgartigimod with the ENHANZE® drug delivery technology (licensed from Halozyme) 
in a Phase 1 clinical trial in healthy volunteers demonstrating a retained PD profile of IV efgartigimod. 

We continue to exploit efgartigimod’s pipeline-in-a-product opportunity and, at the end of 2019, we announced the initiation of 
a proof-of-concept Phase 2 clinical trial in a fourth indication, chronic demyelinating polyneuropathy, or CIDP, a rare neurological 
autoimmune disease. This Phase 2 trial, ADHERE, will evaluate SC ENHANZE® efgartigimod in patients with CIDP.

Beyond efgartigimod, we continue to co-develop our second lead product candidate, cusatuzumab (ARGX-110) (targeting CD70) with 
our collaborator, Cilag GmbH International, an affiliate of the Janssen Pharmaceutuical Companies of Johnson & Johnson, or Cilag, 
for the rare and aggressive hematological cancer acute myeloid leukemia, or AML, as well as high-risk myelodysplastic syndrome, 
or MDS. In December 2016, we started the dose-escalation part of the Phase 1/2 clinical trial of cusatuzumab in combination 
with azacytidine. In December 2018, we reported a 92% response rate in the treated group of newly diagnosed AML patients. The 
transition into the Phase 2 part of this clinical trial was announced in August 2018. In July 2019, Cilag initiated a registration directed 
Phase 2 clinical trial, CULMINATE, of cusatuzumab in combination with azacitidine in patients with newly diagnosed AML, exploring 
two dose levels of cusatuzumab. In addition, a Phase 2 clinical trial in combination with azacytidine and/or venetoclax was launched. 

We have a disciplined strategy to maximize the value of our pipeline whereby we plan to retain development and commercial-
ization rights to those product candidates that we believe we can ultimately commercialize successfully on our own, if they are 
approved. We plan to collaborate on product candidates that we believe have promising potential and benefits in disease areas 
or patient populations that are better served by the resources of larger biopharmaceutical companies. As such, we have entered 
into collaborations with a number of biopharmaceutical companies, including our collaboration with Cilag. In January 2019, we 
received a $300 million upfront payment pursuant to that collaboration and Johnson & Johnson Innovation Inc. invested €176.7 
million (approximately $200.0 million based on the exchange rate in effect as of the date the agreement with Janssen was signed) 
in the form of an equity investment. In addition, in August 2018, our collaborator AbbVie S.À.R.L exercised its exclusive option 
to license ARGX-115 (now code named ABBV-151), a cancer immunotherapy-focused product candidate against the novel target 
glycoprotein A repetitions predominant. In March 2019, AbbVie started a first-in-human clinical trial with ABBV-151, triggering a 
$30 million milestone payment by AbbVie to us.

In May 2019, we announced the addition of two new therapeutic candidates discovered via our IAP, ARGX-117 and ARGX-118, 
to our proprietary antibody pipeline. ARGX-117 is targeting the complement compound C2 with potential in severe autoimmune 
indications and a first-in-human clinical trial is expected in first quarter of 2020. ARGX-118 is addressing Galectin-10 and targets 
airway inflammation. 

Our product candidates are focused on indications for which there is a solid biological rationale and for which we believe there is 
an advantage to utilizing our suite of proprietary and licensed technologies outlined below:

•  Our proprietary SIMPLE AntibodyTM Platform sources antibody V-regions from the immune system of outbred llamas, each of 
which has a different genetic background. The V-region is responsible for targeting a specific antibody to an antigen, which is 
a substance that induces an immune response, and is different for every type of antibody. The llama produces highly diverse 
panels of antibodies with a high human homology, or similarity, in their V-regions when immunized with targets of human 
disease. By contrast, most antibody platforms start with antibodies generated in inbred mice or synthetic antibody library 
systems, approaches that we believe are limited by insufficient antibody repertoires and limited diversity, respectively. Our 
SIMPLE AntibodyTM Platform allows us to access and explore a broad target universe, including novel and complex targets, while 
minimizing the long timelines associated with generating antibody candidates using traditional methods. 

•  Our proprietary Fc engineering technologies—NHance®, ABDEGTM and POTELLIGENT®—focus on engineering the Fc region of 
antibodies in order to augment their intrinsic therapeutic properties. These technologies are designed to enable us to expand 
the therapeutic index of our product candidates, which is the ratio between toxic and therapeutic dose, by modifying their 
half-life, tissue penetration, rate of disease target clearance and potency. 

•  Halozyme’s ENHANZE® subcutaneous drug delivery technology for which we have exclusive access for the FcRn and C2 targets 
and one additional target. The global collaboration and license agreement with Halozyme was announced in February 2019. 
The ENHANZE® technology could potentially shorten drug administration time, reduce healthcare practitioner time, and offer 
additional flexibility and convenience for patients.

Our pipeline of product candidates includes both wholly owned and partnered programs. We refer to programs for which we retain 
the exclusive right to develop and commercialize the product candidate on a worldwide basis as our wholly owned programs. We 
refer to programs for which we have entered into collaboration agreements with third parties for the development and commer-
cialization of the product candidate as our partnered programs.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSWe believe that our clinical expertise and execution capabilities position us well to advance our product pipeline. We expect to 
commercialize certain products ourselves and expect, in certain other indications, to enter into collaborations designed to maximize 
the value of our portfolio. We have assembled a team of over 230 employees and consultants with experience across the spectrum 
of antibody drug discovery, clinical development, business development, market access, and sales and marketing. Members of our 
board of directors, management team and key personnel have extensive experience in the life sciences industry and have previously 
served at companies including Alexion Pharmaceutical, Inc.; Cambridge Antibody Technology Group Plc; Celgene Corporation; 
Galapagos NV; Ablynx NV, GlaxoSmithKline plc; Janssen; Micromet, Inc.; Nicox S.A.; The Procter & Gamble Company; Quintiles IMS 
Holdings, Inc; Shire Plc (now part of Takeda Pharmaceutical Company Limited) and Unilever N.V.

3.1.2.  STRATEGY AND OBJECTIVES

Strategy
Our goal is to deliver therapies that are either first-in-class or best-in-class to patients suffering from severe autoimmune and 
hematological diseases and various cancers for which there exists a significant unmet medical need. We are also focused on attaining 
this goal in a manner that is disciplined for a company of our size. We plan to:

•  Rapidly advance efgartigimod in MG and four additional indications. We are currently developing our lead product candidate, 
efgartigimod, for the treatment of patients with MG, ITP, PV and CIDP and plan to start proof-of-concept clinical development in 
a fifth indication later in 2020. We chose these indications based on the biological rationale of targeting the neonatal Fc receptor, 
or FcRn, thereby reducing the pathogenic immunoglobulin G, or IgG, antibody levels that drive all of these disease states. We 
launched a Phase 3 clinical trial in MG for IV efgartigimod in September 2018 and completed recruitment at the end of 2019 
with topline data anticipated mid-2020, aimed at a first potential approval in MG. We launched a Phase 3 potential registrational 
trial with IV efgartigimod in ITP in December 2019. An additional Phase 3 clinical trial in ITP is expected to start in the second 
half of 2020 evaluating IV efgartigimod for induction of platelet response, and fixed dose SC efgartigimod for maintenance of 
platelet response. We reported interim data for the additional Phase 2 clinical trial of efgartigimod in PV in January 2020 and 
initiated an additional Phase 2 clinical trial in our fourth indication CIDP. In the first half of 2019, we launched a Phase 1 clinical 
trial with the subcutaneous ENHANZE® formulation of efgartigimod; this trial was successfully completed by the end of 2019.
•  Advance cusatuzumab in AML, MDS and adjacent hematological tumors. In December 2016, we initiated an open-label, 
Phase 1/2 clinical trial of cusatuzumab in combination with the standard of care, azacytidine, in newly diagnosed AML and 
high-risk MDS patients. We reported topline results from the dose-escalation part of this clinical trial in December 2018, and we 
announced the transition into the Phase 2 part of this clinical trial in August 2018. In December 2018, we and our partner Cilag 
(Janssen) agreed to a joint global clinical development plan to evaluate cusatuzumab in AML, MDS and other potential future 
indications. In 2019, we initiated a dose-confirming Phase 2 trial, CULMINATE, of cusatuzumab in combination with azacytidine 
in newly diagnosed elderly AML patients who are unfit for intensive chemotherapy. Additionally, a Phase 1b platform study 
was launched to explore combinations with standard AML therapies with the first trial exploring combinations of venetoclax, 
cusatuzumab and azacytidine.

•  Expand applications for our existing product candidates. Our goal is to maximize the commercial potential of our existing 
product candidates by exploring additional indications, as well as formulations that may expand the target patient populations 
within existing indications. For example, our development work in efgartigimod is based on its ability to reduce circulating IgG 
antibodies, and this has given us the ability to leverage a single Phase 1 clinical trial in healthy volunteers into one Phase 3 
and three Phase 2 clinical trials in different indications, MG, ITP, PV and CIDP where we believe this mechanism of action may 
have therapeutic benefit. In addition, we believe there are other autoimmune diseases that may benefit from treatment with 
efgartigimod. We plan to employ a similar strategy of leveraging the strong biological rationale for other product candidates 
into multiple indications, thereby maximizing the value of our pipeline. We also expanded the use of our product candidates 
in existing indications by developing new formulations, such as a subcutaneous version of efgartigimod, which was tested in a 
Phase 1 healthy volunteer clinical trial, that may make our product candidates accessible to larger patient populations, including 
patients requiring chronic therapy, potentially outside of the hospital setting. 

•  Focus our discovery and development efforts on novel and complex targets to generate new first-in-class and best-in-class 
product candidates for autoimmune diseases and hematology/cancer. Our SIMPLE Antibody™ Platform together with the IAP 
allows us to explore novel disease biology and pathways, allows us to access and explore a broad target universe, including 
novel and complex targets, while minimizing the long timelines associated with generating antibody candidates using traditional 
methods. By exploring a broad target universe, we are able to develop a breadth of antibodies to test many different epitopes. 

58  |  Presentation of the Company

Being able to test many different epitopes with our antibodies enables us to search for an optimized combination of safety, 
potency and species cross-reactivity. We believe our Fc engineering and drug delivery technologies will allow us to augment 
our antibodies for maximum therapeutic effect. 

• 

•  Selectively leverage our suite of technologies to seek strategic collaborations and maximize the value of our pipeline. Our 
suite of technologies and productive discovery capabilities have yielded several potential product candidates for which we seek 
to capture value, while maintaining our focus and discipline. We plan to collaborate on product candidates that we believe have 
promising utility in disease areas or patient populations that are better served by the resources of larger biopharmaceutical 
companies. In addition to collaborating on our product candidates, we may also elect to enter into collaborations for third-party 
product candidates for which we believe that our technologies and expertise may be valuable. 
Implement our “argenx 2021” vision to become a global, fully integrated, novel immunology company and independently 
commercialize our product candidates in indications and geographies where we believe we can extract maximum value. We 
plan to independently develop and commercialize those product candidates that we believe have a clear clinical and regulatory 
approval pathway and that we believe we can commercialize successfully ourselves, if approved. Our commercialization strategy 
for any product candidates that are approved will focus on key academic centers, specialist physicians and advocacy groups, as 
well as on providing patients with support programs and maximizing product access and reimbursement. As part of this strategy, 
we are building two commercial franchises in neuromuscular and hematology/oncology disorders, with the potential to expand 
into a third franchise in skin and kidney diseases. In 2021, we expect to launch efgartigimod in the U.S. in its first indication of 
generalized MG, or gMG, if approved. Through the building of commercial franchises, we plan to leverage capabilities and an 
organizational footprint for subsequent potential launches across our broad immunology pipeline.

3.1.3.  COMPETITIV E POS IT ION

We participate in a highly innovative industry characterized by a rapidly growing understanding of disease biology, quickly changing 
technologies, strong intellectual property barriers to entry, and a multitude of companies involved in the creation, development 
and commercialization of novel therapeutics. These companies are highly sophisticated and often strategically collaborate with 
each other. 

We compete with a wide range of pharmaceutical companies, biotechnology companies, academic institutions and other research 
organizations for novel therapeutic antibody targets, new technologies for optimizing antibodies, talent, financial resources, intel-
lectual property rights and collaboration opportunities. Many of our competitors and potential competitors have substantially 
greater scientific, research and product development capabilities as well as greater financial, manufacturing, marketing and sales 
and human resources than we do. In addition, there is intense competition for establishing clinical trial sites and registering patients 
for clinical trials. Many specialized biotechnology firms have formed collaborations with large, established companies to support 
the research, development and commercialization of products that may be competitive with ours. Accordingly, our competitors may 
be more successful than we may be in developing, commercializing and achieving widespread market acceptance. Competition in 
the autoimmune field is intense and involves multiple monoclonal antibodies, other biologics and small molecules either already 
marketed or in development by many different companies including large pharmaceutical companies such as AbbVie Inc. (Humira/
rheumatoid arthritis); Amgen Inc. (Enbrel/rheumatoid arthritis); Biogen, Inc. (Tysabri/multiple sclerosis); GlaxoSmithKline plc, or 
GSK, (Benlysta/lupus); F. Hoffman-La Roche AG, or Roche, (Rituxan/often used off label); and Janssen (Remicade/rheumatoid arthritis 
and Stelera/psoriasis). In some cases, these competitors are also our collaborators. In addition, these and other pharmaceutical 
companies have monoclonal antibodies or other biologics in clinical development for the treatment of autoimmune diseases. In 
addition to the current standard of care, we are aware that Alexion Pharmaceuticals, Inc. is selling Soliris for the treatment of 
adult patients with generalized MG who are anti-acetylcholine receptor antibody positive and that GSK; Roche; Novartis AG; CSL 
Behring; Grifols, S.A.; BioMarin Pharmaceutical Inc.; Curavac; Millenium Pharmaceuticals, Inc., UCB S.A./RA Pharma; Momenta 
Pharmaceuticals, among others, are developing drugs that may have utility for the treatment of MG. We are aware that Rigel 
Pharmaceuticals, Inc.; Dova Pharmaceuticals.; Bristol-Myers Squibb; Shire; Immunomedics; Protalex Inc.; Principia Biopharma 
and others are developing drugs that may have utility for the treatment of ITP. We are aware that Roche is selling Rituxan for the 
treatment of moderate to severe PV and Principia; Alexion and others are developing drugs that may have utility for the treatment 
of PV. Furthermore, we are aware of competing products specifically targeting FcRn and being developed by UCB S.A.; Momenta, 
Inc.; Alexion; Immunovant and Affibody.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSCompetition in the leukemia and lymphoma space is intense, with many compounds in clinical trials by large multinational phar-
maceutical companies and specialized biotech companies. Rituxan (Roche), Adcetris (Seattle Genetics, Inc. /Takeda Pharmaceutical 
Company Ltd), Darzalex (Janssen), Poteligeo (Kyowa Hakko Kirin Co., Ltd.) are some examples of monoclonal antibodies approved 
for the treatment of Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, multiple myeloma or other blood cancers. We are aware of 
AML drugs recently approved by the FDA, such as Daurismo (Pfizer), Mylotarg (Pfizer), Rydapt (Amgen), Vyxos (Jazz Pharmaceuticals, 
Inc.) and IDHIFA (Agios, Inc. and Celgene). In addition, we are aware of a number of other companies with development stage 
programs that may compete with cusatuzumab in the future if it is approved. We anticipate that we will face intense and increasing 
competition as new treatments enter the market and advanced technologies become available. 

There are several monoclonal antibody drug discovery companies that may compete with us in the search for novel therapeutic 
antibody targets, including Adimab LLC; Merus N.V.; Regeneron Pharmaceuticals, Inc.; Xencor Inc. and MorphoSys AG. We are aware 
that a product candidate in development by Scholar Rock, Inc. may compete with ARGX-115 (ABBV-151) and a product candidate 
in development by Ionis Pharmaceuticals, Inc. may compete with ARGX-116, if they are approved. 

3.1.4.  OUR COMPETITIVE S TRENGTHS

We believe that the combination of our technologies, expertise and disciplined focus will enable us to overcome many of the 
challenges associated with antibody drug development and positions us to be a leader in delivering therapies to patients suffering 
from severe autoimmune, and hematological/oncological diseases for which the current treatment paradigm is inadequate. Our 
competitive strengths include:

•  Efgartigimod: Phase 3 product candidate with clinical proof-of-concept in MG, ITP and PV; pipeline-in-a-product opportunity 
in Phase 3 in two indications and Phase 2 clinical trials in two additional indications. We launched a Phase 3 clinical trial in 
MG for our lead product candidate, efgartigimod, in September 2018. We announced full data from the Phase 2 clinical trial in 
ITP in December 2018 and launched a Phase 3 clinical trial, ADVANCE, in this indication at the end of 2019. Also, at the end of 
2019 we initiated a Phase 2 clinical trial, ADHERE, of SC ENHANZE® efgartigimod in CIDP, and we reported interim data of the 
Phase 2 clinical trial of efgartigimod in PV in January 2020. MG, ITP, PV and CIDP are rare, severe autoimmune diseases with 
high unmet medical need. Each indication is characterized by high levels of pathogenic or IgG antibodies, and we specifically 
designed efgartigimod to reduce IgG antibody levels. In a Phase 1 clinical trial of efgartigimod with healthy volunteers, we 
observed a reduction of circulating IgG antibody levels of 50% to 85%. We believe that a reduction of pathogenic IgG antibody 
levels, which are a subset of circulating IgG antibodies in people with autoimmune disease, of at least 30% would be clinically 
meaningful. In addition, all patients in the treatment arm of our Phase 2 clinical trial in MG showed a rapid and deep reduction 
of their total IgG levels and disease improvement was found to correlate with reduction in pathogenic IgG levels. The treated 
ITP patients in the Phase 2 clinical trial showed a correlation between IgG reduction, platelet counts increase and reduction of 
bleeding events. In addition, interim data from the treated PV patients showed a rapid disease control in 18 out of 23 patients 
and fast clinical remission was observed in 5 out of 7 patients receiving the optimized dosing regimen. Based on these data, we 
believe efgartigimod is a pipeline-in-a-product opportunity in these, and potentially other, indications.

•  Productive discovery capabilities through our IAP that fuel a deep pipeline of clinical and preclinical product candidates. We 
are advancing a deep pipeline of both clinical- and preclinical-stage product candidates for the treatment of severe autoim-
mune diseases, hematological disorders and cancer. Leveraging our technology suite and clinical expertise, we have advanced 
six product candidates into late-stage clinical development —efgartigimod, cusatuzumab, ARGX-111, ARGX-109, ARGX-112 
and ARGX-115 (ABBV-151); three into the preclinical stage — ARGX-116, ARGX-117 and ARGX-118; and we currently have 
multiple programs in the discovery stage. We believe this level of productivity affords us a breadth of options with regard to 
independently advancing or partnering our pipeline assets.

•  The ability to exploit novel and complex targets for maximum therapeutic effect. . Our SIMPLE AntibodyTM Platform, which is 
based on outbred llamas, combined with our IAP allows us to explore novel disease biology,and to access and explore a broad 
target universe. We believe the benefit of our platform is that it provides a broader set of human-like V-regions as compared to 
other sources such as mice or synthetic antibody libraries. With this breadth of antibodies, we are able to test many different 
epitopes, which are binding sites on antigens capable of eliciting an immune response. Being able to test many different epitopes 
with our antibodies enables us to search for an optimized combination of safety, potency and species cross-reactivity with the 
potential for maximum therapeutic effect on disease.

60  |  Presentation of the Company

•  The ability to use our proprietary Fc engineering technologies to modulate immune response. We employ technologies—
NHance®, ABDEGTM and POTELLIGENT®—that focus on engineering the Fc region of antibodies in order to augment their intrinsic 
therapeutic properties. These technologies are designed to expand the therapeutic index of our product candidates by modifying 
their half-life, tissue penetration, rate of disease target clearance and potency.

•  Validating strategic collaborations to maximize pipeline value or access complementary technology. Our productive discovery 
capabilities and deep pipeline have provided us with multiple product candidates for which we seek to capture the greatest 
value. We have partnered, and expect to continue to partner, product candidates that we believe have promising utility in 
disease areas or patient populations that are better served by the resources of larger biopharmaceutical companies. As a result, 
we have entered into collaborations with a number of biopharmaceutical companies, including our collaboration with Janssen 
for cusatuzumab, our product candidate targeting CD70 for rare and aggressive hematological cancers and with AbbVie for 
ARGX-115 (ABBV-151), a cancer immunotherapy-focused product candidate against the novel target GARP. In addition, we seek 
partnerships with companies that have complementary technologies. For instance, under the global collaboration and license 
agreement we have with Halozyme for their ENHANCE® subcutaneous drug delivery technology for which we have access for up 
to three targets, including exclusive rights to develop therapeutic products targeting human neonatal Fc receptor FcRn. Under 
the terms of agreement, we paid an upfront payment of $30 million to Halozyme with potential future payments up to $160 
million per selected target subject to achievement of specified development, regulatory and sales-based milestones.

3.2.1.  OUR SUITE OF TECHNOLOGI ES

Harnessing the Therapeutic Potential of Antibodies
Antibodies are Y-shaped proteins used by the immune system to target and clear foreign bodies, including pathogens, such as 
bacteria and viruses, and tumor cells. Antibodies are composed of two structurally independent parts, the variable region, or 
V-region, and the constant, or Fc, region. The V-region is responsible for targeting a specific antibody to an antigen and is different for 
every type of antibody. The Fc region does not interact with antigens, but rather interacts with components of the immune system 
through a variety of receptors on immune and other cells. These interactions allow antibodies to regulate the immune response 
and levels of cell-killing ability, or cytotoxicity, as well as their persistence in circulation and tissues. Fc regions are the same and 
interchangeable from antibody to antibody.

As shown in Figure 1, we apply a unique suite of technologies to create antibodies with optimized V-regions and an enhanced 
Fc region. Used alone or in combination, we believe that our suite of technologies enables us to create product candidates with 
potential first-in-class and best-in-class therapeutic activity against a wide range of targets. 

Our Proprietary SIMPLE AntibodyTM Platform
Our proprietary SIMPLE AntibodyTM Platform sources V-regions from conventional antibodies existing in the immune system of 
outbred llamas. Outbred llamas are those that have been bred from genetically diverse parents, and each has a different genetic 
background. The llama produces highly diverse panels of antibodies with a high human homology in their V-regions when immu-
nized with human disease targets. We then combine these llama V-regions with Fc regions of fully human antibodies, resulting in 
antibodies that we then produce in industry-validated production cell lines. The resulting antibodies are diverse and, due to their 
similarity to human antibodies, we believe they are well suited to human therapeutic use. With this breadth of antibodies, we are 
able to test many different epitopes. Being able to test many different epitopes with our antibodies enables us to search for an 
optimized combination of safety, potency and species cross-reactivity with the potential for maximum therapeutic effect on disease. 
These antibodies are often cross-reactive with the rodent version of chosen disease targets. This rodent cross-reactivity enables more 
efficient preclinical development of our product candidates because most animal efficacy models are rodent-based. By contrast, 
most other antibody discovery platforms start with antibodies generated in inbred mice or synthetic antibody libraries, approaches 
that we believe are limited by insufficient antibody repertoires and limited diversity, respectively. Our SIMPLE AntibodyTM Platform 
allows us to access and explore a broad target universe, including novel and complex targets, while minimizing the long timelines 
associated with generating antibody candidates using traditional methods.

Our proprietary Fc Engineering Technologies
Our antibody engineering technologies—NHance®, ABDEGTM and POTELLIGENT®—focus on engineering the Fc region of antibodies 
in order to augment their interactions with components of the immune system, thereby potentially expanding the therapeutic 
index of our product candidates by modifying their half-life, tissue penetration, rate of disease target clearance and potency. For 
example, our NHance® and ABDEGTM engineering technologies enable us to modulate the interaction of the Fc region with FcRn, 
which is responsible for regulating half-life, tissue distribution 
and pharmacodynamic properties of IgG antibodies. Similarly, 
our POTELLIGENT® engineering technology modulates the 
interaction of the antibody Fc region with receptors located on 
specialized immune cells known as natural killer, or NK, cells. 
These NK cells can destroy the target cell, resulting in enhanced 
antibody-dependent cell-mediated cytotoxicity, or ADCC.

Blood Circulation (pH 7.4)

NHance® and ABDEGTM: Modulation of Fc Interaction 
with FcRn
An illustration of the FcRn-mediated antibody recycling mech-
anism is shown in Figure 2.  Serum proteins, including IgG 
antibodies, are routinely removed from the circulation by cell 
uptake.  Antibodies can bind to FcRn, which serves as a dedi-
cated recycling receptor in the endosomes, which have an acidic 
 return to the circulation by binding 
environment, and then 
with their Fc region to FcRn. 
 Unbound antibodies end up in 
the lysosomes and are degraded by enzymes. Because this Fc/
FcRn interaction is highly pH-dependent, antibodies tightly bind 
to FcRn at acidic pH (pH 6.0) in the endosomes but release again 
at neutral pH (pH 7. 4) in the circulation.

NHance®
NHance® refers to two mutations that we introduce into the 
Fc region of an IgG antibody. NHance® is designed to extend 
antibody serum half-life and increase tissue penetration. In 
certain cases, it is advantageous to engineer antibodies that 
remain in the circulation longer, allowing them to potentially 
exert a greater therapeutic effect or be dosed less frequently. 
As shown in Figure 3,  NHance® antibodies bind to FcRn with 
higher affinity, specifically under acidic pH conditions.  Due 
to these tighter bonds, NHance® FcRn-mediated antibody recy-
cling is strongly favored over lysosomal degradation, although 
some degradation does occur.  NHance® allows a greater 
proportion of antibodies to return to the circulation poten-
tially resulting in increased bioavailability and reduced dosing 
frequency. ARGX-111, ARGX-109, ARGX-117 and a number of 
our discovery-stage programs utilize NHance®.

ABDEGTM
ABDEGTM refers to five mutations that we introduce in the Fc 
region that increase its affinity for FcRn at both neutral and 
acidic pH. In contrast to NHance®, ABDEGTM-modified Fc regions 
remain bound to FcRn if the pH changes, occupying FcRn with 
such high affinity that they deprive endogenous IgG antibodies 
of their recycling mechanism, leading to enhanced clearance 
of such antibodies by the lysosomes. Some diseases mediated 
by IgG antibodies are directed against self-antigens. These 
self-directed antibodies are referred to as autoantibodies. 
We use our ABDEGTM technology to reduce the level of these 
pathogenic auto-antibodies in the circulation by increasing the 
rate at which they are cleared by the lysosomes. ABDEGTM is a 
component in a number of our product candidates, including 
efgartigimod. 

As shown in Figure 4, our ABDEGTM technology can also be 
used with our pH-dependent SIMPLE Antibodies in a mecha-
nism referred to as sweeping. Certain SIMPLE Antibodies bind 
to their target in a pH-dependent manner. These antibodies 
 bind tightly to a target at neutral pH while in circulation, 
and  release the target at acidic pH in the endosome.  
The unbound target is degraded in the lysosome.  However, 
when equipped with our ABDEGTM technology, the therapeutic 
antibodies remain tightly bound to FcRn at all pH levels and 
are not degraded themselves. Instead, they are returned to 
the circulation where they can bind new targets. We believe 
this is especially useful in situations where high levels of the 
target are circulating or where the target needs to be cleared 
very quickly from the system.

POTELLIGENT® modulates the interaction of the Fc region with the Fc gamma receptor IIIa located on specialized immune cells, 
known as NK cells. These NK cells can destroy the target cell, resulting in enhanced ADCC. POTELLIGENT® changes the Fc structure 
by excluding a particular sugar unit such that it enables a tighter fit with the Fc gamma receptor IIIa. The strength of this interaction 
is a key factor in determining the killing potential of NK cells. An independent publication reported that the exclusion of this sugar 
unit of the Fc region increases the ADCC-mediated cell-killing potential of antibodies by 10- to 1000-fold. Cusatuzumab and ARGX-
111 utilize POTELLIGENT® (source: Expert Opin Biol Ther 2006; 6:1161-1173; http://www.tandfonline.com/doi/full/10.1517/1471

Efgartigimod (formerly referred to as ARGX-113)
We are developing our lead product candidate, efgartigimod, for the treatment of patients with MG (Phase 3; recruitment 
completed), ITP (Phase 3) and PV (Phase 2; Phase 3 being prepared), all of which are rare and severe autoimmune diseases associ-
ated with high levels of circulating pathogenic IgG antibodies for which there are few innovative biologic treatments and a severe 
unmet medical need exists. We also initiated a Phase 2 clinical trial in a fourth indication, CIDP, with SC ENHANZE® efgartigimod and 
expect to start clinical development in a fifth indication in 2020. 

Efgartigimod utilizes our ABDEGTM engineering technology and is designed to block the recycling of IgG antibodies, which results in 
their removal from circulation. We believe that our approach presents potential benefits relative to the current standard of care 
for MG, ITP and PV: corticosteroids and immunosuppressants in the early stages, followed by intravenous IgG, or IVIg, and plasma

exchange, or plasmapheresis, as the disease progresses. The current standard of care for CIDP is IVIg. We believe efgartigimod’s 
potential benefits include improved time of onset, increased magnitude and duration of therapeutic benefit, a more favorable safety 
and tolerability profile and a reduced cost burden to the healthcare system. Data reported to-date have shown that efgartigimod 
is well-tolerated, with reductions in pathogenic autoantibodies correlating with improvements in clinical scores.

Efgartigimod in MG – orphan drug status in the U.S. and Europe
We announced full data from a double-blind, placebo-controlled Phase 2 clinical trial of efgartigimod in 24 patients with generalized 
MG = in April 2018. In May 2019, we announced the publication of these Phase 2 results in the peer-reviewed journal, Neurology. 
The Phase 3 ADAPT trial was launched in September 2018 evaluating IV efgartigimod in gMG and data are expected mid-2020; if 
successful, we anticipate submitting a Biologics License Application, or BLA, for efgartigimod in gMG in the fourth quarter of 2020. 
Also, in 2020 we plan to engage with the U.S. Food and Drug Administration (FDA) on a potential bridging strategy for 1,000mg 
subcutaneous SC ENHANZE® efgartigimod in gMG.

Efgartigimod in ITP – orphan drug status in the U.S. and Europe
In 2018, we performed a second Phase 2 clinical trial of IV efgartigimod in 38 patients with ITP for which the full study data were 
published in the peer-reviewed journal, Hematology in December 2019. The Phase 3 program of IV efgartigimod, ADVANCE, was 
initiated in the fourth quarter of 2019 and will evaluate the potential of IV efgartigimod for both induction and maintenance of 
platelet response. The ADVANCE IV+SC Phase 3 trial in ITP is expected to start in the second half of 2020 and will evaluate IV efgar-
tigimod for induction of platelet response and a fixed dose of SC efgartigimod for maintenance. An additional small confirmatory 
IV trial as part of our ITP program is expected to start in the first half of 2020.

Efgartigimod in PV
A Phase 2 proof-of-concept trial of IV efgartigimod is ongoing in PV and positive interim data were presented in the beginning of 
2020 with the full data set expected to be reported during a medical conference during 2020. Based on the positive interim data, 
we are preparing a potential registrational Phase 3 trial which 
is expected to start in the second half of 2020.

Efgartigimod in CIDP
At the end of 2019, we initiated the Phase 2 ADHERE trial of SC 
ENHANZE® efgartigimod in patients with CIDP.

Formulation Options for Efgartigimod
We are developing three formulations of efgartigimod to 
address the needs of patients, physicians and payors across indi-
cations and geographies, including IV efgartigimod and two SC 
formulations (the standalone ENHANCE® SC formulation and the 
SC formulation that is dosed as maintenance after IV induction).

Nerve

Overview of Myasthenia Gravis
MG is an autoimmune disorder associated with muscle weak-
ness that is triggered by IgG autoantibodies. These antibodies 
attack critical signaling proteins at the junction between nerve 
and muscle cells, thereby impairing their communication signals. 
As shown in Figure 5, in MG these autoantibodies either bind 
and occupy or cross-link and internalize the receptor on the 
muscle cells, thereby preventing the binding of acetylcholine, 
the signal sent by the nerve cell. In addition, these autoanti-
bodies can cause destruction of the neuromuscular junction by 
recruiting complement, a potent cell-destroying mechanism of 
the human immune system.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSThe muscle weakness associated with MG usually presents initially in ocular muscles and can then spread into a generalized form 
affecting multiple muscles. MG initially causes droopy eyelids and blurred or double vision due to partial paralysis of eye movements. 
As MG becomes generalized it affects muscles in the neck and jaw, causing problems in speaking, chewing and swallowing. MG can 
also cause weakness in skeletal muscles leading to problems in limb function. In the most severe cases, respiratory function can be 
weakened to the point where it becomes life-threatening. These respiratory crises occur at least once in the lives of approximately 
15% to 20% of MG patients. 

The U.S. prevalence of MG is estimated at approximately 20 cases per 100,000 (source: Philips et al, Ann NY Acad Sci. 2003; www.
myasthenia.org/LinkClick.aspx?fileticket=EjpV6nDv8pU=&tabid=84). Currently, there are an estimated 64,000 MG patients in the 
United States, of which an estimated 55,000 patients are suffering from generalized MG. We believe that the prevalence in Europe 
is at a similar level. Our initial focus is on generalized MG patients whose disease is not well-controlled with corticosteroids and 
immunosuppressants, which we believe represents a majority of generalized MG patients. 

Limitations of Current MG Treatments
Early in their disease, patients are treated with cholinesterase inhibitors, such as pyridostigmine, followed by corticosteroids and 
immunosuppressants. The majority of patients with MG require some form of immunotherapy at some point during their illness. 
Corticosteroids are associated with a number of significant side effects, including bone thinning, weight gain, diabetes, hyperten-
sion, osteoporosis and depression. The side effects of immunosuppressants, depending on the particular immunosuppressant, 
include weakness, sweating, transaminase elevations, neutropenia, including severe neutropenia with infection, acute deep venous 
thrombosis, nausea, vomiting and the incidence of cancer. As MG becomes more advanced, patients can be treated with IVIg and 
plasmapheresis. Both of these approaches are associated with significant side effects. 

Treatment with IVIg is based on the principle of altering the balance between synthesis and degradation of antibodies in the body. 
IVIg treatment results in a large increase in the quantity of IgG antibodies in circulation. This excess of exogenously added IgG anti-
bodies competes with the endogenous autoimmune antibodies for various pathways including the FcRn antibody recycling pathway. 
Saturation of this pathway with exogenous IgG antibodies promotes antibody destruction, which in turn leads to a decrease in the 
level of autoimmune antibodies. IVIg treatment is associated with a number of adverse events including fever, myalgia, headache, 
nausea and impaired kidney function or kidney disease, and IVIg can lead to life-threatening complications such as pulmonary 
edema, acute kidney dysfunction or stroke in elderly patients. 

Plasmapheresis involves collecting blood from a patient and physically removing the IgG antibodies and other serum proteins from 
the plasma before returning it to the patient. Plasmapheresis is also associated with known limitations and drawbacks. Potential 
complications include thrombotic events, bleeding, catheter occlusion, infection, nausea, hypotension and arrhythmias. In most 
cases, these symptoms are mild and transient, but in some cases, they can be severe and life-threatening. 

Both of these approaches place a heavy cost burden on the healthcare system. In addition to the costs of the IVIg or plasmapheresis 
treatment itself, hospitalization of patients receiving these treatments further adds to this cost burden. According to a 2011 study, 
the average short-term cost for utilizing IVIg or plasmapheresis for MG crisis was $78,814 and $101,140 per patient, respectively 
(source: J Clin Neuromuscul Dis. 2011 Dec; 13(2):85–94. doi: 10.1097/CND.0b013e31822c34dd). In addition to patients experiencing 
an MG crisis, we believe a substantial number of MG patients receive chronic IVIg or plasmapheresis for which they require frequent 
hospitalization.

In October 2017, the FDA and European Medicines Agency approved the use of Soliris® for the treatment of generalized MG patients 
who have autoantibodies directed against the acetylcholine receptor. Soliris is an anti-C5 antibody blocking the activity of comple-
ment recruited by the pathogenic IgGs directed against the acetylcholine receptor at the neuromuscular junction. However, Soliris 
does not address the blocking of the acetylcholine receptor by pathogenic IgGs, nor the receptor cross-linking and internalization 
by these IgGs. In addition, a subset of MG patients is known to have anti-MuSK antibodies, which are known not to activate the 
complement cascade. The price of Soliris in MG amounts to approximately $700,000 per patient per year, placing, we believe, a 
substantial cost burden on the health care system. 

Finally, a minority of MG patients undergo thymectomy, the surgical removal of the thymus, an immune organ which is believed to 
play a role in the pathogenesis of the disease. 

66  |  Our Product Candidates

For MG patients who have advanced to the point where they are not well-controlled with corticosteroids and immunosuppressants, 
we believe efgartigimod may offer advantages over IVIg and plasmapheresis, including the potential to deliver a faster onset of 
action, a larger and longer lasting therapeutic effect and an improved safety and tolerability profile. In addition, a subcutaneous 
formulation of efgartigimod could further expand its use in patients requiring chronic therapy, potentially outside of the hospital 
setting. 

Overview of Primary Immune Thrombocytopenia
ITP is a bleeding disease caused by an autoimmune reaction in which a patient develops antibodies that attack and destroy their 
own platelets, which are blood cells that help blood to clot, or their own platelet-forming cells. ITP, which develops for no known 
reason, is differentiated from secondary immune thrombocytopenia, which is associated with other illnesses, such as infections 
or autoimmune diseases, or which occurs after transfusion or taking other drugs, such as cancer drugs. Platelet deficiency, or 
thrombocytopenia, can cause bleeding in tissues, bruising and slow blood clotting after injury. ITP affects approximately 72,000 
patients in the United States (sources: Current Medical Research and Opinion, 25:12, 2961-2969; Am J Hematol. 2012 Sep; 87(9): 
848–852; Pediatr Blood Cancer. 2012 Feb; 58(2): 216–220).

Limitations of Current ITP Treatments
Treatment for ITP is focused on either reducing the autoimmune activity that is causing accelerated platelet destruction and 
allowing the platelets to recover on their own, or directly stimulating platelet production with specific growth factors. Patients 
with less severe ITP are treated with corticosteroids and immunosuppressants, which are associated with significant side effects 
also seen with such treatment of other autoimmune diseases, such as MG. For more severe ITP, splenectomy is sometimes used as 
treatment, although its use is rapidly declining. The use of thrombopoietin receptor agonists, which stimulate the production and 
differentiation of platelets and are approved for last-line therapy, is increasing. Patients diagnosed with severe ITP are primarily 
offered IVIg or, to a lesser extent, plasmapheresis. 

IVIg can raise the platelet count within days in most patients, but the effect is usually transient. IVIg introduces high levels of exog-
enously added IgG antibodies to the blood stream that compete with the patient’s autoantibodies for various pathways including 
the FcRn-dependent antibody recycling pathway, thereby lowering the impact of the autoantibodies. IVIg treatment for ITP requires 
intravenous dosing of up to 2 g/kg per day of IVIg and is associated with many of the adverse events seen with IVIg treatment of 
other autoimmune diseases, such as MG as described above. Both IVIg and plasmapheresis when used to treat ITP carry a high cost 
burden on the healthcare system as they do when used to treat MG. 

The production of platelets in patients refractory to other treatments can be stimulated by drugs such as romiplostim (Nplate) 
or eltrombopag (Promacta) that mimic thrombopoietin. While these therapies lead to increases in blood platelet counts, they 
do not address the underlying cause of the disease, which is the destruction of platelets by the immune system. Romiplostim 
(Nplate),Eltrombopag (Promacta) and Fostamatinib (Rigel) are approved as last-line therapy for ITP and have generated global 
revenues of $584 million and $635 million in 2016, respectively (source: Amgen Inc. Annual Report on Form 10-K for Fiscal Year 
Ended December 31, 2016 (page 126)). 

Overview of Pemphigus Vulgaris
PV is an autoimmune disorder associated with mucosal and skin blisters that lead to pain, difficulty swallowing and skin infection. 
This chronic, potentially life-threatening disease is triggered by IgG autoantibodies targeting desmoglein-1 and -3, which are present 
on the surface of keratinocytes and important for cell-to-cell adhesion in the epithelium. Autoantibodies targeting desmogleins 
result in loss of cell adhesion, the primary cause of blister formation in PV. Similar to MG and ITP, disease severity of PV correlates 
to the amount of pathogenic IgGs targeting desmogleins. 

Currently, there are an estimated 17,400 pemphigus patients in the United States, of which an estimated 13,100 patients are 
suffering from PV. We believe that the prevalence in Europe is at a similar level. Our initial focus is on mild-to-moderate PV patients 
who are either newly diagnosed or not well-controlled with corticosteroids and immunosuppressants. 

Several disease activity measurements exist for the clinical evaluation of PV patients, including the pemphigus disease area index, 
or PDAI; autoimmune bullous skin disorder intensity score, or ABSIS; and the PV activity score, or PVAS. The PDAI is reported to 
have the highest validity and is recommended for use in clinical trials of PV.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSLimitations of Current PV Treatments
The goals for the treatment of PV are twofold: (1) decrease blister formation and promote healing of blisters and erosions, and (2) 
determine the minimal dose of medication necessary to control the disease process. The current treatment regime for PV patients 
is limited. Typically, corticosteroids are used as first-line therapy, possibly in combination with immunosuppressants. Patients not 
well-controlled by these therapies may then receive IVIg or Rituxan. The latter is becoming more common in the treatment regime 
due to the significant side effects associated with corticosteroids and immunosuppressants. Rituxan was recently approved by 
the FDA for the treatment of moderate to severe PV. Rituxan carries infusion reaction risks, including anaphylaxis, and the risk of 
opportunistic infections, including progressive multifocal leukoencephalopathy, a rare and usually fatal viral disease. 

Even with aggressive PV therapy, it takes two to three weeks for blisters to stop forming and about six to eight weeks for blisters 
to heal. Even with IVIg and Rituxan, complete remissions may take several months, and some patients do not respond to these 
treatments. The serious complications that can arise from use of these drug classes leave a large unmet medical need for effective 
therapy with a faster onset of action and better safety profile. 

Overview of Chronic Inflammatory Demyelinating Polyneuropathy
CIDP is a chronic autoimmune disorder of peripheral nerves and nerve roots caused by an autoimmune-mediated destruction 
of the myelin sheath, or myelin producing cells, insulating the axon of the nerves and enabling speed of signal transduction. The 
cause of CIDP is unknown, but abnormalities in both cellular and humoral immunity have been shown. CIDP is a chronic and 
progressive disease: onset and progression occur over at least eight weeks in contrast with the more acute Guillain-Barré-syndrome. 
Demyelination and axonal damage in CIDP lead to loss of sensory and/or motor neuron function, which can lead to weakness, 
sensory loss, imbalance and/or pain. CIDP affects approximately 16,000 patients in the United States.

Limitations of Current CIDP Treatments
Most CIDP patients require treatment and intravenous immunoglobulin, or IVIg, which is the preferred first-line therapy. 
Glucocorticoids and plasma exchange are used to a lesser extent as they are either limited by side effects upon chronic use, in the 
case of glucocorticoids, or invasiveness of the procedure and access, which is restricted to specialized centers in case of plasma 
exchange. Alternative immunosuppressant agents are typically reserved for patients ineligible for or refractory to IVIg, glucocorticoids 
or plasma exchange. While IVIg therapy can usually control CIDP, most patients require repeated treatments every two to six weeks 
for many years. This is due to the fact that IVIg monotherapy does not usually lead to long-term remission. IVIg introduces high levels 
of exogenously added IgG antibodies to the blood stream that compete with the patient’s autoantibodies for various pathways, 
including the FcRn-dependent antibody recycling pathway, thereby lowering the impact of the autoantibodies. IVIg treatment for 
CIDP requires intravenous dosing of up to 2 g/kg per day of IVIg and is associated with many of the adverse events seen with IVIg 
treatment of other autoimmune diseases, such as MG. Both IVIg and plasmapheresis, when used to treat CIDP, carry a high cost 
burden on the healthcare system as they do when used to treat myasthenia gravis, or MG, or ITP. CIDP is the largest indication for 
IV/SC Ig in the United States.

Our Solution: efgartigimod
Our lead product candidate, efgartigimod, is an antibody Fc fragment that we believe has the potential to overcome many of the 
limitations of the current standard of care for MG, ITP, PV and CIDP, including with respect to time of onset, magnitude and duration 
of therapeutic benefit and safety profile. We developed efgartigimod using our ABDEGTM Fc engineering technology. 

Efgartigimod targets FcRn with high affinity, thereby reducing levels of all four classes of IgG antibodies, which are referred to as IgG1, 
IgG2, IgG3 and IgG4. In the case of MG, the large majority of patients have autoantibodies of the IgG1 and IgG3 classes, while in the 
case of ITP these autoantibodies consist mainly of the IgG1 class. In the case of PV, the pathogenic autoantibodies consist mainly 
of the IgG1 and IgG4 class. As shown in Figure 6, efgartigimod’s mechanism of action is to block the recycling of IgG antibodies and 
remove them from circulation. Antibodies are routinely removed from circulation by being internalized into cells, where they can 
either become destined for degradation in the lysosomes or recycled back into circulation.

68  |  Our Product Candidates

IgG antibodies not bound to FcRn are degraded, while those 
bound to FcRn are recycled back into circulation.  As a result 
of our ABDEGTM technology and the modifications we made 
to the Fc region, efgartigimod binds to FcRn with high affinity 
making this receptor unavailable to circulating IgG antibodies. 
 The IgG antibodies can then no longer effectively be rescued 
and end up in the lysosomes where they are degraded. 
Compared to alternative immunosuppressive approaches, such 
as B-lymphocyte, or B-cell, depleting agents, efgartigimod acts 
in a highly selective manner by reducing IgG antibody levels, 
while leaving levels of antibodies of the immunoglobulin A, 
or IgA, immunoglobulin M, or IgM, and immunoglobulin D, 
or IgD, types as well as all components of the innate immune 
system intact.

Based on our preclinical studies and early clinical trial results, 
we believe that efgartigimod has the potential to reduce levels 
of pathogenic IgG antibodies. Our clinical data suggest that 
efgartigimod reduces circulating IgG antibodies more rapidly 
than current therapies, which we believe could translate into 
faster therapeutic benefit if replicated with respect to patho-
genic IgG antibodies. Our clinical data also suggest that the 
quantity of efgartigimod required to achieve and maintain 
suppression of circulating antibodies is lower than the levels 
of IVIg required for therapeutic benefit, which could translate 
into fewer infusions, shorter infusion time and a more favor-
able safety and tolerability profile.

Figure 6: Efgartigimod’s mechanism of action blocks the

In addition to MG, ITP, PV and CIDP, we believe there are other autoimmune diseases that may benefit from the mechanism of 
action of efgartigimod therapy. We intend to pursue initial approval for MG and then plan to expand to ITP and, potentially, PV and 
CIDP because these diseases have significant unmet medical needs. We then intend to expand our clinical development efforts for 
efgartigimod into additional indications also mediated by pathogenic IgG antibodies. Pathogenic auto-antibodies have been shown 
to be associated with other neuromuscular diseases such as Guillain-Barré, Lambert Eaton, chronic inflammatory demyelinating 
polyradiculoneuropathy; with other hematological diseases such as hemolytic anemia; and with other autoimmune blistering 
diseases such as bullous pemphigoid and epidermyolysis bullosa; as well as with systemic lupus erythematosus and multiple sclerosis, 
which affect larger numbers of patients. 

Global and Broad Clinical Development Plan
We are currently evaluating efgartigimod in Phase 3 clinical trials in MG and ITP. A global, multi-center Phase 3 ADAPT clinical trial, 
including ADAPT+ one-year open-label extension study, is currently ongoing. The ADAPT trial completed patient enrolment at the end 
of 2019 and we expect topline data from this trial by mid-2020. For ITP, a global Phase 3 program includes two registrational trials 
to be run concurrently. The first trial, ADVANCE is launched and will evaluate 10mg/kg IV efgartigimod on top of standard of care 
medication. The second trial is expected to be launched in the second half of 2020 to evaluate 10mg/kg IV efgartigimod to induce 
IgG antibody reduction and clinical response followed by fixed dose 330mg subcutaneous SC efgartigimod to maintain clinical benefit.

A Phase 2 proof-of-concept clinical trial for treatment of pemphigus vulgaris is ongoing and positive interim proof-of concept data 
were reported in early 2020. The detailed results of Phase 2 trial are expected to be presented during a medical meeting in 2020. 
The reported interim data support advancing to a registrational trial, which is expected to start in the second half of 2020.

Finally, at the end of 2019, we initiated the Phase 2 ADHERE trial of SC ENHANZE® efgartigimod in CIDP patients, and we expect to 
start clinical development in a fifth indication in 2020.

We conducted a randomized, double-blind, placebo-controlled Phase 2 clinical trial to evaluate the safety and tolerability, efficacy, 
pharmacodynamics and pharmacokinetics of efgartigimod. This clinical trial was conducted in 24 generalized MG patients with 
an MG-Activity-of-Daily-Living, or MG-ADL, score of 5 points or higher, with more than 50% of the score consisting of non-ocular 
items, and who are on a stable dose of cholinesterase inhibitors, steroids and/or immunosuppressants which make up the typical 
first- and second-line standard-of-care therapies. We conducted the clinical trial at 19 sites across Europe, Canada and the United 
States. Patients were randomly assigned to two arms of 12 patients each. Patients in one treatment arm received 10 mg/kg of 
efgartigimod, and the other treatment arm received placebo. All patients continued to receive the standard of care. Dosing took 
place during a three-week period which included four weekly doses of efgartigimod or placebo. Patients received follow-up for 
eight weeks after treatment. 

The primary objectives of this Phase 2 clinical trial were to evaluate the safety and tolerability of efgartigimod with primary endpoints 
evaluating the incidence and severity of adverse events and serious adverse events, and evaluating vital signs, electrocardiogram 
and laboratory assessments. Secondary endpoints of the trial included efficacy as measured by the change from baseline of the 
MG-ADL; Quantitative MG; and MG Composite disease severity scores and the impact on quality of life as measured by the MG 
Quality of Life score. In addition, an assessment of pharmacokinetics, pharmacodynamics and immunogenicity was performed. All 
24 enrolled patients were evaluable. 

Phase 2 Topline Results
We announced full data from this Phase 2 clinical trial in April 2018 and the data were published in the peer-reviewed journal, 
Neurology, in 2019. The primary endpoint analysis demonstrated efgartigimod to be well-tolerated in all patients, with most treat-
ment emergent adverse events or TEAEs observed characterized as mild (CTCAE Grading 1 and 2). No TEAEs severity with CTCAE 
Grade 3 or higher were reported. No clinically significant laboratory, vital signs and/or electrocardiogram findings were observed. 
No laboratory abnormality including albumin similar to the findings cynomolgus monkeys and in clinical trials. No TEAE leading to 
discontinuation, no serious TEAE and no deaths were reported during the trial. The observed tolerability profile was consistent with 
the Phase 1 healthy volunteer trial as well as our Phase 2 clinical trial in ITP.

All TEAEs reported, as well as TEAEs deemed to be drug-related by the investigator in at least two patients, are summarized in Table 1.

The secondary endpoint measures relating to efficacy showed efgartigimod treatment resulted in a strong clinical improvement over 
placebo as measured by all four predefined clinical efficacy scales during the entire duration of the trial. Patients in the treatment 
arm showed rapid onset of disease improvement, with clear separation from placebo one week after the first infusion. 

83% of patients treated with efgartigimod achieved a clinically meaningful response (MG-ADL>2). 75% of patients treated with 
efgartigimod had a clinically meaningful and statistically significant improvement in MG-ADL scores (at least a two-point reduction 
from baseline) for a period of at least six consecutive weeks versus 25% of patients on placebo (p = 0.0391). 

Clinical benefit in the efgartigimod treatment group maximized as of one week after the administration of the last dose, achieving 
statistical significance over the placebo group (p = 0.0356) on the MG-ADL score. Increasing differentiation was observed between 
the efgartigimod treatment group versus placebo with increasing MG-ADL and QMG thresholds at day 29 (1 week after last dosing) 
as shown in Figure 7.

Analysis of the pharmacokinetic and pharmacodynamic endpoints was generally consistent with the findings from the Phase 1 clinical 
trial. We observed disease improvement to be correlated with reduction in pathogenic IgG levels. Total IgG reduction in patients 
was consistent with the Phase 1 healthy volunteer trial showing a mean maximum IgG reduction of up to 70.7% among treated 
patients. Reduction of IgG levels was consistent across IgG subtypes, including AChR autoantibodies (IgG1 and IgG3).

In line with findings in the Phase 1 healthy volunteer trial, positive anti-drug antibody, or ADA, titers were detected in a limited 
number of patients. In the Phase 2 clinical trial, positive post-dosing ADA titers were detected in four out of 12 patients receiving 
efgartigimod and in three out of 12 patients receiving placebo. In one active-treated patient, positive post-dose ADA titers were 
detected as of two weeks after the last infusion, and these titers may have the tendency to slightly increase over the course of the 
trial. In line with the results obtained in the Phase 1 healthy volunteer trial, the majority of ADA signals in active-treated patients 
were just above the detection limit of the assay and were typically only found once or twice during the course of the trial. Positive 
post-dose ADA titers had no apparent effect on efgartigimod pharmacokinetics or pharmacodynamics.

Phase 2 Clinical Trial in ITP
We completed a randomized, double-blind, placebo-controlled Phase 2 clinical trial to evaluate the safety, efficacy and pharmacoki-
netics of efgartigimod in 38 adult primary ITP patients, who have platelet counts lower than 30 x 109/L while being on a stable dose 
of standard-of-care treatments consisting of corticosteroids, permitted immunosuppressants or thrombopoietin receptor agonists, 
or after having undergone a splenectomy or while being monitored under a ‘watch & wait’ approach. We conducted the clinical 
trial at 19 clinical centers across eight countries in the European Union. Patients were randomly assigned to three arms of 12 or 13 
patients for the placebo or efgartigimod arms, respectively. All patients in this clinical trial on a drug standard-of-care treatment 
were to continue to receive their stable dose of standard-of-care treatment as per the protocol. One treatment arm received 5 
mg/kg efgartigimod, the second arm received 10 mg/kg efgartigimod and the third arm received placebo. Dosing took place in a

three-week period, which included four weekly doses of efgartigimod or placebo. Patient follow-up continued for 21 weeks after 
treatment. Patients from all three cohorts were eligible to enroll in a one-year open label extension study at the 10mg/kg dose of 
efgartigimod, subject to meeting enrollment criteria, including platelet counts lower than 30 x 109/L.

Phase 2 Topline Results
The primary objectives of this Phase 2 clinical trial were to evaluate safety and tolerability of efgartigimod with primary endpoints 
evaluating the incidence and severity of adverse events and serious adverse events, and evaluating vital signs, electrocardiogram 
and laboratory assessments. Secondary objectives included evaluation of efficacy, based on platelet count, use of rescue treatment 
and bleeding events, pharmacokinetics, pharmacodynamics, and immunogenicity.

We announced full data from this Phase 2 clinical trial in December 2018 and in December 2019, we announced a peer-reviewed 
publication of these data in The Journal of Hematology. The primary endpoint analysis demonstrated efgartigimod to be well-tol-
erated in all patients, with most treatment emergent adverse events (TEAE) observed characterized as mild (CTCAE Grading 1 and 
2). Two serious TEAEs were reported for 2 (15.4%) out of 13 patients both in the efgartigimod 10 mg/kg treatment group (1 case of 
bronchitis and 1 case of thrombocytopenia); both serious TEAE were considered not related to the trial treatment and both serious 
TEAEs were downgraded after the study database locked. No deaths were reported during the study. The observed tolerability 
profile was consistent with the Phase 1 healthy volunteer trial as well as our Phase 2 clinical trial in MG.

All non-bleeding TEAEs reported, as well as non-bleeding TEAEs deemed to be drug-related by the investigator in at least two 
patients, are summarized in Table 2.

Clinically meaningful improvements in platelet counts were seen across ITP classifications and standard of care. 46% of patients 
demonstrated improved platelet count to ≥ 50x109/L during two or more visits in each of the 5 mg/kg and 10 mg/kg dosing cohorts 
compared to 25% in the placebo cohort. 67% of patients in the OLE trial demonstrated improved platelet count to ≥ 50x109/L during 
two or more visits following the first dosing cycle. Responders from the 10 mg/kg arm in the primary trial all responded again 
upon retreatment in the OLE trial. Onset of platelet count reaching 50x109/L for the first time ranged from week 1 to week 10, 
consistent with disease heterogeneity. For efgartigimod-treated patients with clinically meaningful platelet responses (≥ 50x109/L 
during two or more visits), the mean duration of platelet response was 40 days versus 16 days for placebo treated patients, with 
responses lasting the trial duration. 

38% of efgartigimod-treated patients showed durable platelet count improvements to clinically meaningful and statistically significant 
levels of ≥ 50x109/L for at least 10 cumulative days, compared to 0% of placebo patients (p=0.03). These data are summarized in 
figures 8 and 9.

The frequency of bleeding related events, as defined in the protocol, was evaluated separately. This was done due to the nature of 
the disease, as low platelet levels in ITP patients may induce bleeding events in a proportion of patients, and signs and symptoms 
vary widely. Bleeding events were assessed using three metrics—adverse event reporting, the WHO scale and the ITP-BAT scale—
and showed that efgartigimod reduced bleeding events across each scale. Adverse event reporting showed no severe bleeding 
events in any patient, mild bleeding events only were reported in the 10 mg/kg arm and mild and moderate in the 5 mg/kg and 
placebo arm. Incidence of bleeding events was reduced by efgartigimod treatment as assessed by the WHO bleeding scale, with 
separation from placebo as early as the third dose in the 10 mg/kg arm. Incidence of bleeding events in the skin was reduced by 
efgartigimod treatment as assessed by the ITP-BAT bleeding scale, with no clear signal of bleeding events in the mucosa or organs 
in either treatment arm. Efgartigimod treatment resulted in clear correlation between IgG reduction, platelet count improvement 
and bleeding event reduction. 

Analysis of the pharmacokinetic and pharmacodynamic endpoints was generally consistent with the findings from the Phase 1 
clinical trial as well as the MG Phase 2 clinical trial. Lasting IgG reductions were consistent with levels achieved in previous studies. 
All efgartigimod-treated patients showed a rapid and deep reduction of total IgG levels, consistent with the pharmacodynamic 
effects observed in previous clinical trials. Reduction of IgG levels was consistent across IgG subtypes. Reduction in platelet-asso-
ciated autoantibodies were observed in the majority of patients with clinically meaningful platelet increase. Low titer of anti-drug 
antibodies was detected in 16.7% of placebo patients and 30.8% of treated patients in the 10 mg/kg arm with no apparent effect 
on pharmacokinetics or pharmacodynamics.

Phase 2 Clinical Trial in PV
We are conducting an open label, non-controlled Phase 2 clinical trial to evaluate the safety, efficacy, pharmacodynamics and phar-
macokinetics of efgartigimod in a minimum of 12 patients with mild to moderate PV who are either newly diagnosed or relapsing. 
We conduct the clinical trial at 12 sites across Europe, Ukraine and Israel. The trial design comprises three cohorts of a minimum of 
four patients each. The first cohort received 10 mg/kg of efgartigimod in four weekly doses as induction therapy, followed by five 
weeks of maintenance therapy with efgartigimod dosed at 10 mg/kg at week 1 and week 5 of the maintenance period, followed 
by an eight-week follow-up period with no dosing of efgartigimod. In newly diagnosed patients and relapsing patients off-therapy, 
efgartigimod will be dosed as monotherapy, in absence of standard of care therapy. In relapsing patients on prednisone, efgartigimod 
will be dosed on top of a stable dose of prednisone during the induction phase. The prednisone dose may be changed (decreased 
or increased) from the beginning of the maintenance phase up to study end according to standard of care (i. e., corticosteroids, 
immunosuppressants, IVIg, plasma exchange and rituximab). An Independent Data Monitoring Committee (IDMC) may recommend 
adapting the dose during both the induction and the maintenance period, or the dosing frequency at maintenance, or the duration 
of dosing during the maintenance period with a maximum of two extra doses per cohort for a following cohort based on the outcome 
of the previous cohort. In case of a dose increase, the maximum dose would be 25 mg/kg.

The primary objectives of this Phase 2 clinical trial are to evaluate safety and tolerability of efgartigimod, with primary endpoints 
evaluating the incidence and severity of adverse events and serious adverse events and evaluating vital signs, electrocardiogram, 
physical examination abnormalities and laboratory assessments. Secondary objectives include evaluation of pharmacodynamics 
including assessment of total IgG and pathogenic IgG levels, efficacy based on the PDAI score, pharmacokinetics, and immunogenicity. 

Phase 2 Interim Results and Next Steps
In the first cohort of the Phase 2 trial, six mild to moderate PV patients with no or low-dose corticosteroid therapy were treated 
with efgartigimod. Disease control was reached in three out of six patients in one week, which was characterized by patients having 
signs of healing of existing lesions and the absence of new lesions forming. One patient reached disease control after four weeks. 
Two patients had progression of disease. In all patients exhibiting disease control, a mean maximum reduction in Pemphigus Disease 
Area Index (PDAI) of 55% correlated with a mean maximum decrease in pathogenic autoantibodies levels of 57%. No meaningful 
anti-drug antibody signals were reported.

The IDMC evaluated the results of the first patient cohort and determined the tolerability profile to be favorable. The IDMC 
recommended maintaining the dose at 10 mg/kg but adjusted the dosing frequency and duration of the maintenance phase for 
the next cohort. The second patient cohort will dose every two weeks during the maintenance phase and will add two additional 
administrations for a period of eight total weeks of maintenance, up from six weeks in cohort 1. 

The Phase 2 proof-of-concept clinical trial for treatment of pemphigus vulgaris is still ongoing but a we reported additional positive 
proof-of-concept interim data in early 2020 where 23 patients were evaluated. 

The data demonstrated a clear correlation between pathogenic IgG reduction and the Pemphigus Disease Area Index score 
improvement (Fig. 11). 78% (18/23) of patients achieved rapid disease control; median time to disease control for both mono-
therapy and combination therapy was 14-15 days. A 
fast-clinical remission (CR) was observed in 70% (5/7) 
of patients receiving an optimized dosing regimen; 
CR was achieved within 2-10 weeks. The optimized 
dosing  regimen  was  determined  to  be  at  least 
biweekly dosing of efgartigimod in combination with 
oral prednisone (0.25-0.5mg/kg). This data suggested 
the potential for corticosteroid sparing treatment. 
In addition, an independent data review committee 
concluded tolerability to be favorable.

Figure 11: IgG reduction correlates to PDAI score improvement in responders

Patients still in trial are included in the extended 
dosing cohort and detailed results of Phase 2 trial are 
expected to be presented during a medical meeting in 
2020. We believe that this data supports advancing to 
a potential registrational trial expected to start in the 
second half of 2020.

Phase 1 Clinical Trial for Subcutaneous Formulation of efgartigimod (fixed maintenance dose used after IV 
induction)
In addition to the intravenous product formulation of efgartigimod, we are also developing a subcutaneous product formulation 
designed to enable administration of efgartigimod to larger patient populations, including patients requiring chronic therapy, 
potentially outside the hospital setting. 

We evaluated the intravenous and subcutaneous formulations of efgartigimod head-to-head in a preclinical cynomolgus monkey 
model. The results suggest that both formulations result in comparable half-life in circulation of efgartigimod, a favorable bioavail-
ability of 75% of the subcutaneous formulation and a comparable pharmacodynamic effect shown by reduction of total IgG 
antibodies. 

Our Product Candidates    |  75 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSWe initiated a Phase 1 clinical trial in healthy volunteers for a subcutaneous formulation for the treatment of chronic autoimmune 
diseases. The open label, Phase 1 trial enrolled 32 healthy volunteers and included three treatment arms: one each of single 
dose SC and IV efgartigimod, and one evaluating an IV induction followed by a SC maintenance dose. In the single dose treatment 
arms, the data showed the SC formulation to have comparable half-life, pharmacodynamics and tolerability to the IV formulation, 
and a bioavailability of approximately 50%. In addition, initial IV dosing followed by weekly 300 mg (2 ml) SC administration of 
efgartigimod provided sufficient exposure to maintain IgG suppression at a steady state IgG reduction of approximately 50%. The 
data also suggested a favorable tolerability profile and no meaningful anti-drug antibody signals were reported. The SC formulation 
supports key manufacturing improvements, including a high product concentration (150mg/ml), low viscosity and optimal stability.

Phase 1 Clinical Trial ENHANZE® SC efgartigimod (standalone SC formulation)
In addition to the subcutaneous product formulation of efgartigimod, we developed a standalone SC formulation of efgartigimod 
as part of our collaboration with Halozyme based on a co-formulation of efgartigimod with Halozyme’s proprietary ENHANZE® drug 
delivery technology (hyaluronidase, rHuPH20), designed to enable a smooth and convenient SC administration with larger volumes 
of efgartigimod with short injection times. 

We initiated a Phase 1 clinical trial in healthy volunteers for the ENHANZE® subcutaneous formulation for the treatment of chronic 
autoimmune diseases. The open label, Phase 1 trial enrolled 33 healthy volunteers and included four treatment arms: three with 
fixed doses of ENHANZE® SC efgartigimod, and one evaluating a body weight-based dose of ENHANZE® SC efgartigimod. Clear 
dosedependent reductions in mean total IgG and the different IgG subtypes concentration were observed. Using PK-PD modelling, 
we selected a dose of 1000 mg ENHANZE® SC efgartigimod to be equivalent to the 10 mg/kg IV efgartigimod formulation with 
respect to the effect on IgG levels. 

The ENHANZE® SC efgartigimod formulation was quickly injected with mean injection times lower than 1 minute for the smallest 
dose. 

Single dose of ENHANZE® SC efgartigimod of 750 mg, 1250 mg, 1750 mg, or 10 mg/kg was well tolerated by all healthy subjects. 
No obvious TEAE were reported beyond mild and transient injection site reactions, in line with reported ENHANZE® coformulation 
findings. No meaningful immunogenicity was reported.

First-in-Human Clinical Development Plan and Clinical Data
We have completed enrollment in a double blind, placebo-controlled Phase 1 clinical trial in healthy volunteers to evaluate the 
safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of single and multiple doses of efgartigimod. In the 
first part of the clinical trial, 30 subjects were randomized to receive a single dose of efgartigimod or placebo ranging from 0.2 
mg/kg to 50 mg/kg. In the second part of the clinical trial, 32 subjects were randomized to receive multiple ascending doses of 
efgartigimod or placebo up to a maximum of 25 mg/kg.

We announced interim data from this Phase 1 clinical trial in June 2016 and at a workshop we sponsored in conjunction with the 
American Society of Hematology annual meeting in December 2016. We expect that the full results from this clinical trial will be 
published in a peer reviewed journal during the first half of 2017.

Single Ascending Dose
We observed that a single two-hour infusion of 10 mg/kg efgartigimod was associated with an approximate 50% reduction of 
circulating IgG antibody levels. We observed that a reduction of circulating IgG antibody levels persisted for more than four weeks 
after the last dose, as shown in Figure 8. We believe this sustained reduction would be clinically meaningful if replicated with 
respect to pathogenic IgG antibodies because IVIg and plasmapheresis typically result in a 30% to 60% reduction in pathogenic IgG 
antibody levels.

Administration of efgartigimod at single doses up to 25 mg/kg was reported to be well tolerated and administration of a single dose 
of 50 mg/kg was reported to be moderately tolerated. There were no drug or infusion related serious adverse events associated 
with doses up to 50 mg/kg. The most frequently reported drug related adverse events included abnormal white blood cell count, 
increased C reactive protein levels, headache, dizziness and chills. All of these adverse events were mild or moderate and reported 

76  |  Our Product Candidates

only in the two highest dose groups (25 mg/kg and 50 mg/kg). While efgartigimod was associated with a decrease in the levels of 
IgG antibodies, there were no observed changes in IgM or IgA levels or serum albumin observed in the clinical trial, suggesting that 
efgartigimod has the potential to be a highly selective immunosuppressant.

Figure 8. Selective reduction of IgG by administration of 
efgartigimod to healthy volunteers in the single as-cending 
dose part of our Phase 1 clinical trial

Multiple Ascending Dose
In the multiple ascending dose part of the Phase 1 clinical trial, repeat administration of both 10 mg/kg and 25 mg/kg of efgartigimod 
every seven days, four doses in total, and 10 mg/kg every four days, six doses in total, was associated with a gradual reduction in 
levels of all four classes of IgG antibodies by 60% to 85%, with 10 mg/kg dose results shown in Figure 9. For all doses, we observed 
the reduction in circulating IgG antibody levels to persist for more than four weeks after the last dose with levels below 50% at 
approximately three weeks and did not return to baseline levels for more than one month. Pharmacokinetic analysis of serum 
baseline levels of efgartigimod indicates that it has a half-life of approximately three to four days with no drug accumulation 
following subsequent weekly dosing. The prolonged activity on the levels of IgG antibodies is consistent with the mechanism of 
action of efgartigimod and the effect of the ABDEGTM technology on increasing the intracellular recycling of efgartigimod. Similar 
to the single ascending dose part, no significant reductions in IgM, IgA or serum albumin were observed.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSAdministration of multiple efgartigimod doses of 10 mg/kg and 25 mg/kg were reported to be well tolerated. One serious adverse 
event, hyperventilation, was observed in the multiple ascending dose part. This event, which occurred six days after drug adminis-
tration, was considered by the clinical investigator as unlikely to be related to efgartigimod. Some patients had changes to C reactive 
protein levels that were considered clinically significant. The most frequently reported drug related adverse events included head-
ache, feeling cold, chills and fatigue, all of which were mild or moderate and reported only in the highest dose group of 25 mg/kg.

In a limited number of pre and post dose samples originating from both active and placebo treated individuals, positive ADA 
titers were detected. During the single ascending dose part of the clinical trial, three out of 20 subjects on drug and one out of 10 
subjects on placebo showed positive post dose ADA titers. During the multiple ascending dose part of the clinical trial, one out 
of 23 subjects on drug and two out of eight subjects on placebo showed positive post dose ADA titers. Signals typically were just 
above the detection limit of the assay and were only found once during the clinical trial for the majority of subjects. No increase 
of ADA titers over time for individual subjects was observed, nor had any of the subjects with at least one positive ADA sample an 
apparent different pharmacokinetic/pharmacodynamic profile.

Cusatuzumab (formerly referred to as ARGX-110)
We are developing cusatuzumab in hematological cancer indications, currently AML, as well as high risk MDS. We are developing 
cusatuzumab with our collaborator Janssen. See paragraph 3.6 “Material Contracts/Collaboration Agreements”.

AML is rare and aggressive hematological cancer for which significant unmet medical needs exist. MDS, a rare bone marrow disorder, 
is often a precursor to AML. cusatuzumab is a SIMPLE AntibodyTM designed to potently block the CD70/CD27 interaction and kill 
CD70-positive cells via its potent antibody effector functions through the use of POTELLIGENT® technology. 

Cusatuzumab is currently being evaluated in an open label registration directed Phase 2 clinical trial, CULMINATE, in combination 
with azacytidine, in newly diagnosed AML patients who are unfit for intensive chemotherapy or in patients with high-risk MDS. A 
Phase 1b platform trial is also underway in various AML subpopulations and settings with an initial trial evaluating combinations of 
cusatuzumab, venetoclax and azacitadine.

We reported results for the first 12 patients from the dose-escalation part of the Phase 1/2 clinical trial in combination with azacyt-
idine in AML or high-risk MDS in December 2019, which demonstrated a favorable tolerability profile of the combination therapy 
and suggested evidence of biological activity across the evaluated doses. 

In addition, we reported results of the Phase 2 part of the Phase 1/2 clinical trial in relapsed or refractory CD70-positive CTCL 
patients and an open label Phase 1 clinical trial in patients with nasopharyngeal carcinoma.

Overview of Acute Myeloid Leukemia and Myelodysplastic Syndrome
AML is a hematological cancer characterized by excessive proliferation of myeloid stem cells and their failure to properly differen-
tiate into mature white blood cells. AML is the second most common subtype of leukemia in adults. In the United States, AML has 
an incidence of approximately 22,000 new cases annually (Siegel et al., Cancer J Clin 2015) AML is generally a disease of elderly 
people, with more than 60% of diagnosed patients being older than 60 years, and AML is uncommon before the age of 45. The 
average five-year survival rate for patients with AML is 27%, but there are significant differences in prognosis depending on several 
factors, including the age of the patient at diagnosis. For patients under the age of 45, the five-year survival rate is approximately 
57%, while for those over the age of 65 it is only 6%. There are likely multiple reasons for this discrepancy, including the ability of 
younger patients to tolerate more aggressive therapy.

Current first-line treatments in AML typically involve aggressive chemotherapy, including alkylating agents and cytarabine potentially 
followed by stem cell transplantation, for younger patients with the aim to induce remission. This therapy is not recommended for 
older patients or patients with comorbidities, who are often treated with hypomethylating agents. We believe there is a significant 
need for safer, more effective AML treatments that can also be used in elderly patients. Because relapse is often due to leukemic 
stem cells present next to the malignant AML cells, or blasts, therapies targeting both blasts and leukemic stem cells may be more 
efficacious than chemotherapy only and could increase survival rates.

MDS also affects bone marrow cells, reducing their ability to produce red and white blood cells or platelets. In the United States, 
MDS has an incidence of approximately 13,000 new cases annually. There are currently an estimated 60,000 MDS patients in the 
United States. Approximately 75% of MDS patients are older than 60 years of age when diagnosed, and, like with AML, as the 
population ages the disease prevalence is expected to rise. Some MDS patients are at high risk to develop AML and are treated in 
a similar way as AML patients.

Our Solution: cusatuzumab
We developed cusatuzumab using our SIMPLE AntibodyTM Platform and the POTELLIGENT® Fc engineering technology. Cusatuzumab 
binds to the cell surface protein CD70 with high affinity, blocking the interaction between CD70 and its receptor CD27 and targeting 
CD70 expressing cells for destruction by multiple immune pathways. CD70 is a cell surface protein that is highly expressed in cancer, 
including in T-cell and B-cell lymphomas, leukemias and certain solid tumors. In normal tissues, CD70 expression is either low or 
absent. Binding of CD70 to its receptor, CD27, initiates a cascade of intracellular events leading to cell proliferation and survival. As 
a byproduct of CD70 binding to CD27, the extracellular portion of CD27 is cleaved, creating a soluble form of CD27 known as sCD27, 
which can easily be measured. sCD27 may serve as a biomarker for CD70 activity, potentially allowing us to identify target patients 
based on the likelihood of response to treatment, monitor disease progression and measure the impact of anti-CD70 therapy. In 
AML, CD70 is also expressed on leukemic stem cells. Leukemic stem cells are demonstrated to give rise to a large population of more 
mature leukemic blasts which lack self-renewal capacity in AML. Leukemic stem cells reside in the bone marrow and are considered 
difficult to target specifically. Preliminary data from the first set of patients in our clinical trial suggest cusatuzumab could be active 
both at the circulating and bone marrow blast level and at the leukemic stem cell level. Cusatuzumab exhibits potent ADCC and 
antibody dependent cellular phagocytosis potential through the use of POTELLIGENT® technology as well as complement-dependent 
cytotoxicity leading to the killing of cells expressing CD70.

Clinical Development Plan
In December 2016, we initiated an open label Phase 1/2 clinical trial of cusatuzumab at three sites in Switzerland for the treatment 
of newly diagnosed AML or high-risk MDS patients. We reported interim results from the dose-escalation part of this clinical trial 
in December 2019. 

The registration directed Phase 2 CULMINATE clinical trial is currently enrolling up to 150 patients with previously untreated AML 
who are not eligible for intensive chemotherapy. In this two-part trial, patients will first be randomized to receive one of two dose 
levels of cusatuzumab (10mg/kg and 20mg/kg) in combination with azacytidine (75mg/m2) followed by an expansion cohort to 
evaluate efficacy of the selected dose of cusatuzumab. A Phase 1b platform trial is also underway in various AML subpopulations 
and settings with the initial trial evaluating combinations of cusatuzumab, venetoclax and azacitadine; additional trials are expected 
to launch under this platform trial in the first half of 2020. A randomized Phase 2 trial in higher-risk myelodysplastic syndromes 
(MDS) is expected to start in the first half of 2020. A data update of the cusatuzumab development program is expected in 2020.

In addition, cusatuzumab was evaluated in an open-label Phase 1/2 clinical trial in relapsed or refractory CD70-positive CTCL patients 
and an open-label Phase 1 clinical trial in patients with nasopharyngeal carcinoma. Prior to this, cusatuzumab was evaluated in an 
extensive Phase 1 clinical trial in patients with advanced malignancies expressing CD70, following a stepwise adaptive clinical trial 
design enrolling a total of 86 patients (of whom 85 patients have been treated).

Phase 1/2 Clinical Trial in Combination with Azacytidine in Patients with AML or High-Risk MDS (ongoing)
We are evaluating cusatuzumab in an open label, dose-escalating Phase 1/2 clinical trial to evaluate its safety, tolerability and efficacy 
in combination with azacitidine in newly diagnosed AML patients unfit for chemotherapy or high-risk MDS patients. The clinical 
trial was initiated in December 2016. All patients in this clinical trial are receiving cusatuzumab in combination with 75 mg/m2 
azacitidine (standard of care for AML). Patients receive two weeks of cusatuzumab monotherapy prior to starting the combination 
dosing. During the Phase 1 dose-escalation part of the clinical trial, four doses of cusatuzumab, 1 mg/kg, 3 mg/kg,10 mg/kg and 
20 mg/kg administered bi-weekly are being evaluated. We enrolled 12 patients in the Phase 1 part. 

26 AML patients were enrolled in the Phase 2 part of its Phase 1/2 clinical trial using a 10 mg/kg dose of cusatuzumab. This is a 
multi-center clinical trial conducted in Europe.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSWe reported updated interim results for the 12 evaluable patients from the Phase 1 dose-escalation part of this clinical trial in 
December 2019 at the ASH annual meeting, representing the data as of February 2019. Six out of twelve Phase 1 patients were still 
on treatment at the time of the interim data. These interim results showed for the first 12 patients that no dose-limiting toxicity 
was observed for cusatuzumab and that cusatuzumab was overall reported to be well-tolerated with signs of clinical activity. To 
date, the tolerability profile of cusatuzumab in this Phase 1/2 clinical study in combination with azacitidine appears to be similar 
to what we observed in the other cusatuzumab clinical trials. We believe that the observed Grade 3 and 4 hematological toxicity 
for cusatuzumab in combination with azacitidine corresponds to the reported safety profile of azacitidine monotherapy and can be 
seen in Table 2 below. No grade 5 TEAEs were observed.

More specifically at the time of the interim data, 12 out of 12 AML (100%) patients showed a response, including complete remission 
in eight out of 12 patients, complete remission with incomplete blood count recovery in two out of 12 patients and partial remission 
in two out of 12 patients. One of the patients who achieved a complete remission successfully bridged to allogeneic stem cell 
transplant after five cycles. One patient discontinued from the study following an adverse event. Three patients responded during 
cusatuzumab monotherapy in the first two weeks.

The primary endpoint of the Phase 2 part of the clinical trial is efficacy, and secondary endpoints include safety and characterization 
of pharmacokinetics and immunogenicity.

Of the 26 evaluable patients (out of 27 recruited patients) under analysis, we observed an overall response rate of 23% (one 
complete response, five partial responses and eight patients with stable disease). Patients received a 1 mg/kg or 5 mg/kg dose of 
cusatuzumab. Cusatuzumab was well tolerated at both doses with a total of 106 treatment-emergent adverse events (TEAE) reported 
in 26 patients. Most common was pyrexia and asthenia (5 patients each). Forty events in 16 patients were considered drug-related 
by the investigator of which infusion-related reactions (IRRs) were the most common (22 events in 8 patients). Eighteen SAEs were 
reported in 11 patients, one was considered drug related.

Phase 1 Part of Phase 1 /2 Clinical Trial in Patients with Advanced Malignancies Expressing CD70
Cusatuzumab was evaluated in an extensive Phase 1 part of a Phase 1/2 clinical trial in patients with advanced malignancies 
expressing CD70, following a stepwise adaptive clinical trial design enrolling a total of 86 patients (of whom 85 patients have been 
treated). No dose-limiting toxicities were observed. The most frequent grade 3 and 4 drug-related adverse events were fatigue in 
48.2% of patients and mild (Grade 1–2) infusion-related reactions in 34.1% of patients. Other monoclonal antibodies engineered 
using POTELLIGENT® or similar third-party products that augment ADCC such as mogamulizumab, obinutuzumab and imgatuzumab 
also have infusion-related reaction rates of 24% to 77%. Premedication with acetaminophen, antihistamines and/or corticosteroids 
are used to reduce the impact of infusion-related reactions.

There were 83 serious adverse events seen in 42 of these pre-treated patients. Many patients who enrolled in this study have failed 
more than one prior therapy. All drug-related adverse events referenced in this paragraph were evaluated by the investigators 
according to the Common Terminology Criteria for Adverse Events guidelines (CTCAE v4.03). One Grade 1 (pyrexia), seven Grade 2 
(infusion-related reactions), four Grade 3 (febrile neutropenia, anaemia, thrombocytopenia and fatigue—included in Table 6) and 
no Grade 4 serious adverse events were reported by the investigator as being drug-related. 23 patient deaths were reported in the 
phase 1 clinical trial, of which 17 deaths were attributed to disease progression. One patient death (Grade 5), which was deemed 
drug-related by the investigator, occurred in a heavily pre-treated patient with Waldenstrom Macroglobulinemia and was attributed 
to sepsis and general condition deterioration.

Note: All Grade 3 drug-related adverse events. No Grade 4 drug-related adverse events reported. All other serious adverse events 
were considered non-drug-related by the treating investigator. In the dose-escalation part of this clinical trial, the half-life of ARGX-
110 was observed to be approximately 13 days. Anti-drug antibodies were detected in 50% of all patients, the majority of which 
were seen at the 0.1 mg/kg and 1 mg/kg doses.

We are developing ARGX-117 with therapeutic potential in both orphan and large autoimmune inflammatory diseases. ARGX-117 
is a highly differentiated therapeutic antibody equipped with our proprietary Fc engineering technology NHance® that addresses a 
novel target in the classic pathway of the complement cascade. With a potentially differentiated mechanism of action, ARGX-117 
represents a broad pipeline opportunity across several autoantibody-mediated indications and may have a synergistic effect with 
lead autoimmune compound efgartigimod.

The classical pathway of the complement system is composed of a series of proteins that are activated when IgG or IgM autoan-
tibodies bind to their targets. This mechanism contributes to tissue damage and organ dysfunction in a number of autoimmune 
inflammatory diseases. The ARGX-117 target is key in the lysis of antibody-decorated cells and is active when an immune reaction 
is taking place. 

We obtained the rights to ARGX-117 as part of our Innovative Access Program through which we identified the work on this antibody 
with Broteio Pharma. argenx and Broteio launched a collaboration in 2017 to conduct research, with support from the University of 
Utrecht, to demonstrate preclinical proof-of-concept of the mechanism of ARGX-117. Based on promising preclinical data generated 
under this collaboration agreement, we have exercised the exclusive option to license the program and assumed responsibility for 
further development and commercialization.

A phase 1 trial of ARGX-117 in healthy volunteers is expected to begin in the first quarter of 2020. Multiple doses and formulations 
(IV and SC with Halozyme ENHANZE® technology) will be evaluated as part of dose-finding work. Following analysis of this Phase 
1 data =, we expect to launch the Phase 2 program in multifocal motor neuropathy (MMN) (which fits within our neuromuscular 
franchise) and develop ARGX-117 in additional indications.

ARGX-118
We have exercised our option to exclusively acquire rights to ARGX-118, a highly differentiated antibody against Galectin-10, the 
protein of Charcot-Leyden crystals, which are implicated as a major contributor to severe asthma and to the persistence of mucus 
plugs. ARGX-118 has the following differentiated features:

I.

III. 

acts on a novel target intended to address mucus plugging, a large unmet need in airway inflammation;
unique mechanism of action with observed crystal-dissolving properties; and
broad potential in severe airway inflammation diseases where mucus plugging plays a key role, including lung attack or asthma 
exacerbation, allergic bronchopulmonary aspergillosis, and chronic rhinosinusitis with nasal polyps.

ARGX-118 was developed under a collaboration with VIB, a life sciences research institute based in Flanders, Belgium. Lead opti-
mization work on ARGX-118 for airway inflammation will continue in 2020.

The following is the pipeline for our partnered product candidates and discovery programs. For more information on our collabo-
rations, see section 3.6 “Material Contracts/Collaboration Agreements”.

ARGX-112 (partnered with LEO Pharma)
We are developing ARGX-112 for the treatment of dermatologic indications involving inflammation, together with our collaboration 
partner LEO Pharma. 

ARGX-112 employs our SIMPLE AntibodyTM technology and blocks the interleukin-22 receptor, or IL-22R, in order to neutralize the 
signaling of cytokines implicated in autoimmune diseases of the skin. 

The program is in a Phase 1 clinical trial and LEO Pharma is responsible to fund the clinical development of the program. 

ARGX-115 (ABBV-151) (partnered with AbbVie)
ARGX-115 (ABBV-151) is being developed as a cancer immunotherapy against the novel target GARP by our collaborator AbbVie. 

ARGX-115 (ABBV-151) employs our SIMPLE AntibodyTM technology and works by stimulating a patient’s immune system after a 
tumor has suppressed the immune system by co-opting immunosuppressive cells such as Tregs. 

In August 2018, AbbVie exercised its exclusive license option to develop and commercialize ARGX-115 (ABBV-151). ARGX-
115/ ABBV-151 is currently being explored in a phase 1 clinical trial by Abbvie (https://www.clinicaltrials.gov/ct2/show/
NCT03821935?term=NCT03821935&draw=2&rank=1). 

ARGX-116 (partnered with Staten Biotechnology)
We are developing ARGX-116 for the treatment of dyslipidemia, together with our collaboration partner Staten Biotechnology. 

ARGX-116 employs our SIMPLE AntibodyTM technology and blocks APOC3, a metabolic target involved in triglyceride metabolism. 

ARGX-116 is the first of up to three research programs under the collaboration. Under the terms of the collaboration, the parties 
are jointly responsible for conducting research under a mutually agreed research program, with Staten reimbursing us for all costs 
of carrying out our research responsibilities under each research program. 

In December 2018, Staten Biotechnology announced that it will collaborate with Novo Nordisk A/S to co-develop ARGX-116. 

ARGX-114 (partnered with AgomAb)
ARGX-114 is an HFG-mimetic SIMPLE AntibodyTM directed against the MET receptor.

ARGX-109 (partnered with Genor Biopharma)
ARGX-109 employs our SIMPLE Antibody and NHance® technologies and blocks interleukin 6, or IL 6, a cell signaling protein that is 
an important driver of inflammatory response implicated in the transition from acute to chronic inflammation. 

In October 2012, we entered into an exclusive license agreement with Bird Rock Bio, Inc. (formely known as RuiYi Inc. and Anaphore, 
Inc.), to develop and commercialize ARGX-109. In 2018, Bird Rock Bio and argenx mutually agreed to terminate this exclusive license 
agreement. Genor Biopharma, a sublicensee of Bird Rock Bio, will continue to develop ARGX-109 for the Chinese market. 

Innovative Access Program
We have developed a program designed to secure access to early, cutting edge targets, which we call our Innovative Access Program. 
Through our Innovative Access Program, we are able to serially collaborate with leading academic labs by providing them access to 
our SIMPLE AntibodyTM Platform technology with the goal of expediting the validation of new targets and accelerating the addition 
of new product candidates to our pipeline. In return, we receive early access to these targets and provide academic groups or 
biotechnology companies a simple path to clinical validation and future commercialization of promising ideas in which we and the 
academic lab or biotechnology company both share in the upside potential. 

Our Product Candidates    |  83 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSOne example of the value of the Innovative Access Program is ARGX-115 (ABBV-151), which was developed in collaboration with 
the de Duve Institute / Université Catholique de Louvain. We provided antibodies to the academic groups to help validate the 
target. This in turn, allowed the groups to advance their work successfully, including the facilitation of supportive publications. 
Subsequently, this program formed the basis of our collaboration with AbbVie. ARGX-115 (ABBV-151) exemplifies how our Innovative 
Access Program enables us to generate product candidates against novel targets that may be of high interest for collaboration with 
biopharmaceutical partners. Another example is ARGX-116, which was discovered in close collaboration with disease biology experts 
from Staten Biotechnology, an emerging biotechnology company specialized in the field of dyslipidemia. 

In March 2017, we entered into a collaboration under our Innovative Access Program with Broteio Pharma B.V. to develop an 
antibody against a novel target in the complement cascade, ARGX-117. Under the terms of the agreement, we and Broteio jointly 
developed the complement-targeted antibody to seek to establish preclinical proof-of-concept using our proprietary suite of tech-
nologies. Upon successful completion of these studies, we exercised an exclusive option to license the program in March 2018 and 
assumed responsibility for further development and commercialization.

3.3.  Manufacturing and Supply

We utilize third-party contract manufacturers who act in accordance with the FDA’s good laboratory practices, or GLP, and current 
good manufacturing practices, cGMP, for the manufacture of drug substance and product. Currently, we contract with Lonza Sales 
AG, or Lonza, based in Slough, UK and Singapore, for all activities relating to the development of our cell banks, development of our 
manufacturing processes and the production of all drug substance, thereby using validated and scalable systems broadly accepted 
in our industry. We use additional contract manufacturers to fill, label, package, store and distribute investigational drug products. 

Efgartigimod, cusatuzumab, ARGX-111 and ARGX-112 are each manufactured using an industry-standard mammalian cell culture 
of a Chinese hamster ovary cell line that expresses the product, followed by multiple purification and filtration steps typically used 
in producing monoclonal antibodies. 

All of our antibodies are manufactured by starting with cells, which are stored in a cell bank. We have one master cell bank for 
each product manufactured in accordance with cGMP. Half of each master cell bank is stored at a separate site with the goal that, 
in case of a catastrophic event at one site, sufficient vials of the master cell bank would remain at the alternative storage site to 
continue manufacturing. 

3.4.  Intellectual Property

3.4.1.  INTRODUCTION

We strive to protect the proprietary technologies that we believe are important to our business, including pursuing and maintaining 
patent protection intended to cover the platform technologies incorporated into, or used to produce, our product candidates, the 
compositions of matter of our product candidates and their methods of use, as well as other inventions that are important to our 
business. In addition to patent protection, we also rely on trade secrets to protect aspects of our business that are not amenable 
to, or that we do not consider appropriate for, patent protection, including certain aspects of our llama immunization and antibody 
affinity maturation approaches. 

Our commercial success depends in part upon our ability to obtain and maintain patent and other proprietary protection for 
commercially important technologies, inventions and know-how related to our business, defend and enforce our intellectual prop-
erty rights, particularly our patent rights, preserve the confidentiality of our trade secrets and operate without infringing valid and 
enforceable intellectual property rights of others. 

The patent positions for biotechnology companies like us are generally uncertain and can involve complex legal, scientific and factual 
issues. In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued, and its scope 
can be reinterpreted and even challenged after issuance. As a result, we cannot guarantee that any of our platform technologies 

84  |  Manufacturing and Supply

and product candidates will be protectable or remain protected by enforceable patents. We cannot predict whether the patent 
applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents 
will provide sufficient proprietary protection from competitors. Any patents that we hold may be challenged, circumvented or 
invalidated by third parties. 

As of January 1, 2020, our patent estate (which includes both owned and in-licensed patent rights) included 26 issued U.S. patents, 
30 pending U.S. patent applications, 143 issued foreign patents (including eight granted European patents that have been validated 
into 104 national patents) and 114 pending foreign patent applications (including 12 pending European patent applications).

3.4.2.   PLATFORM TECHNOLOGIES

With regard to our platform technologies, we own or have rights in patents and patent applications directed to our SIMPLE 
AntibodyTM discovery platform, the ABDEGTM and NHance® platforms and the POTELLIGENT® platform.

With regard to our SIMPLE AntibodyTM discovery platform, we own a patent family containing six issued U.S. patents with compo-
sition of matter claims directed to chimeric antibodies containing variable domains comprising CDRs obtained from conventional 
heterotetrameric llama antibodies fused to one or more domains of a human antibody, polynucleotides encoding such chimeric 
antibodies, libraries of expression vectors comprising cDNA sequences encoding camelid antibodies, method claims directed to the 
preparation of such chimeric antibodies, and methods of modulating the binding of a human target antigen to its ligand or receptor 
by administering such a chimeric antibody. The U.S. patents are expected to expire in 2029 to 2033. In addition, the patent family 
contains patents that have been granted in Australia, Europe and Israel, and at least five patent applications pending in various other 
countries and regions in North America, Europe and Asia. In addition, we have a second patent family containing patents granted in 
the United States and Australia, and eight patent applications pending in the United States and other countries in North America, 
Europe and Asia, with composition of matter claims directed to a chimeric antibody containing variable regions with CDRs derived 
from a llama antibody and certain amino acid substitutions corresponding to amino acids present in a human germline variable 
region. The granted U.S. patent and the pending U.S. patent application, if issued as a patent, are expected to expire in 2029. 

With regard to the ABDEGTM platform, we co-own with, and exclusively license from, the University of Texas, a patent family 
containing a pending U.S. patent application with composition of matter claims directed to an isolated FcRn-antagonist comprising 
an variant immunoglobulin Fc region having an increased affinity for an Fc gamma receptor relative to a wild-type IgG1 Fc region, 
and method of use claims directed to a method of using such an FcRn-antagonist to treat certain antibody mediated disorders. The 
U.S. patent application, if issued as a U.S. patent, is expected to expire in 2034. In addition, we have at least 10 patent applications 
pending in various other countries and regions in North America, South America, Europe and Asia. In addition, we own a second 
patent family containing pending patent applications in the United States and 14 other jurisdictions with claims directed to methods 
of reducing the serum levels of an Fc-containing agent in a subject by administering to the subject an FcRn-antagonist containing 
a variant immunoglobulin Fc region containing certain amino acid substitutions. A U.S. patent, if issued from the U.S. patent 
application, is expected to expire in 2036. 

With regard to the NHance® platform, we have exclusively licensed from the University of Texas two U.S. patents with composition of 
matter claims directed to an IgG molecule comprising a variant human Fc domain, and method of use claims directed to a method 
of blocking FcRn function in a subject by providing to the subject such an IgG molecule. The U.S. patents are expected to expire in 
2027 to 2028. The patent family also includes a granted European patent. 

With regard to the POTELLIGENT® platform, which is currently used in the production of our cusatuzumab and ARGX-111 product 
candidates, we have non-exclusively licensed from BioWa certain patent rights that relate to different aspects of the POTELLIGENT® 
platform.

with composition of matter claims directed to a combination of antibodies or a multi-specific antibody, where one of the antigen 
binding regions in the combination of antibodies or the multi-specific antibody binds the epitope bound by the ARGX-111 antibody. 
The U.S. patent is expected to expire in 2033.

3.4.4.  PRODUCT CANDIDATES: PARTNE RE D P RO G R AM S

With regard to the ARGX-115 (ABBV-151) product candidate, we co-own with, and exclusively license from, the Ludwig Institute 
for Cancer Research and Université Catholique de Louvain, a pending U.S. patent application with composition of matter claims 
directed to an antibody that binds GARP the presence of TGF-b and method of use claims directed to the use of such an antibody 
in the treatment of cancer. A U.S. patent, if issued from the U.S. patent application, is expected to expire in 2034, without taking 
a potential patent term extension into account. In addition, the patent family contains at least 10 patent applications pending in 
various other countries and regions in North America, South America, Europe and Asia. In addition, we co-own with, and exclusively 
license from, the Université Catholique de Louvain patent applications pending in the United States and Europe with composition 
of matter claims directed to an antibody that binds an epitope of a complex formed by human GARP and TGF-b and method of use 
claims directed to the use of such an antibody in the treatment of cancer. A U.S. patent, if issued from the U.S. patent application, 
is expected to expire in 2034. Furthermore, ARGX-115 (ABBV-151) incorporates or employs the SIMPLE AntibodyTM technology 
platform, which is covered by one or more of the patents and patent applications discussed above under “Platform Technologies.”

With regard to the ARGX 109 product candidate, we have a pending U.S. patent application with composition of matter claims 
directed to ARGX 109. A U.S. patent, if it were to issue, would be expected to expire in 2033, without taking a potential patent term 
extension into account. We also have counterpart patents and pending patent applications in various jurisdictions, including North 
America, Europe and Asia. Furthermore, ARGX 109 incorporates or employs the SIMPLE Antibody technology and the NHance® 
technology, which is covered by one or more of the patents and patent applications discussed above under “Platform Technologies.”

86  |  Intellectual Property

With regard to the ARGX-112 product candidate, we have a pending international application with composition of matter claims 
directed to an antibody that binds human IL-22R. A U.S. patent, if it were to issue, that claims priority to the international applica-
tion would be expected to expire in 2037, without taking a potential patent term extension into account. Furthermore, ARGX-112 
incorporates the SIMPLE AntibodyTM technology, which is covered by one or more of the patents and patent applications discussed 
above under “Platform Technologies.”

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most 
countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional patent application. 

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

3.4.5.  TRADE SECRET PROTECTI ON

In addition to patent protection, we also rely on trade secret protection for our proprietary information that is not amenable to, 
or that we do not consider appropriate for, patent protection, including, for example, certain aspects of our llama immunization 
and antibody affinity maturation approaches. However, trade secrets can be difficult to protect. Although we take steps to protect 
our proprietary information, including restricting access to our premises and our confidential information, as well as entering into 
agreements with our employees, consultants, advisors and potential collaborators, third parties may independently develop the 
same or similar proprietary information or may otherwise gain access to our proprietary information. As a result, we may be unable 
to meaningfully protect our trade secrets and proprietary information.

3.5.  Tendencies

The Company is in pre-clinical and clinical development phase and has not yet established commercial production and sales, and 
consequently does not hold any products in stock intended for sale. 

There has been no significant change in either (i) the financial performance or (ii) the financial position of the Company’s group 
since the balance sheet date of December 31 2019 up to the date of this Registration Document. For more information, please refer 
to chapter 1 “Risk Factors”, chapter 3 “Business” and to note 30 “Commitments” of the IFRS consolidated financial statements.

3.6.  Collaboration Agreements

We have a disciplined strategy to maximize the value of our pipeline whereby we plan to retain all development and commercial-
ization rights to those product candidates that we believe we can ultimately commercialize successfully, if approved. 

We have partnered, and plan to continue to partner, product candidates that we believe have promising utility in disease areas or 
patient populations that are better served by resources of larger biopharmaceutical companies. We expect to continue to collaborate 
selectively with pharmaceutical and biotechnology companies to leverage our discovery platform and accelerate product candidate 
development. We have entered into multiple collaboration agreements with pharmaceutical partners. Below are summaries of our 
agreements with pharmaceutical partners.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESS3.6.1.  OUR STRAT EGIC PARTNERSHIP WI TH JAN S SEN (FO R CU SAT UZUM AB)

In December 2018, we entered into a collaboration agreement with Cilag GmbH International, an affiliate of Janssen, to jointly 
develop and commercialize cusatuzumab. 

We have granted Janssen a license to the cusatuzumab program to develop, manufacture and commercialize cusatuzumab. For the 
US, the granted commercialization license is co-exclusive with us, while outside the US, the granted license is exclusive to Janssen. 
We and Janssen will assume certain development obligations, and will be jointly responsible for all research, development and 
regulatory costs relating to the cusatuzumab.

Under the terms of the agreement, Janssen has paid us $300 million in an upfront, non-refundable and non-creditable payment. 
In conjunction with the collaboration agreement, we entered into an investment agreement with JJDC, Inc., or JJDC, an affiliate of 
Johnson & Johnson. At the closing of the transaction in January 2019, JJDC purchased 1,766,899 newly issued shares, representing 
4.68% of our then outstanding shares at a price of €100.02 per share ($113.19 based on the exchange rate in effect as of the date 
the payment was received), for a total of €176.7 million (approximately $200.0 million based on the exchange rate in effect as of 
the date the payment was received).

We are eligible to receive potentially up to $1.3 billion in development, regulatory and commercial milestone payments, in addition 
to tiered royalties on sales for the territory outside of the U.S. at percentages ranging from the low double digits to the high teens, 
subject to customary reductions. In December 2019 we announced the achievement of the first milestone of $ 25 million for achieve-
ment of an enrollment milestone in first Phase 2 trial under the collaboration. Janssen will be responsible for commercialization 
worldwide. We retain the option to participate in co-commercialization efforts in the U.S., where the companies have agreed to 
share royalties on a 50/50 basis, and outside the U.S., Janssen will pay double-digit sales royalties to us. The agreement includes 
customary standstill and lock-up provisions. 

Under the terms of the collaboration agreement, we agreed to a joint global clinical development plan to develop cusatuzumab in 
AML, MDS and other potential indications in the future. Unless otherwise determined by the parties, Janssen shall be responsible 
for conducting the development activities specified in the global clinical development plan, subject to certain diligence obligations. 
The parties have equal decision-making authority and shall make consensus decisions regarding the global clinical development 
plan, with certain exceptions related to the territory outside of the U.S. Development costs shall be borne by both parties based 
on a cost sharing arrangement. 

With respect to commercialization activities in the U.S., we shall have the right, but not the obligation, to elect to perform certain 
of the commercial efforts. Janssen has sole responsibility, at its sole cost and expense, to commercialize cusatuzumab outside of 
the U.S., subject to certain diligence obligations.

Unless earlier terminated upon mutual agreement, for material breach or as otherwise specified in the agreement, the collaboration 
term ends on a product-by-product, country-by-country basis, upon the expiration of all payment obligations in such country. With 
respect to the U.S., the agreement shall survive so long as any product covered by the agreement is being sold in the U.S. For the 
outside of U.S. territory, the royalty term expires on a product-by-product and country-by-country basis on the date that is the later 
of (i) 10 years after the first commercial sale of such product sold in that country, (ii) such time as there are no valid claims covering 
such product or (iii) the expiration of regulatory exclusivity for such product in such country.

In December 2019, we achieved the first pre-defined clinical milestone under the global collaboration and license agreement with 
Cilag GmbH International, triggering a $25 million payment.

3.6.2.  OUR STRATEGIC PARTNERSHIP WI TH ABBV I E (FOR ARG X-115 (AB BV-151))

In April 2016, we entered into a collaboration agreement with AbbVie S.À.R.L., or AbbVie, to develop and commercialize ARGX-115 
(ABBV-151). Under the terms of the collaboration agreement, we were responsible for conducting and funding all ARGX-115 (ABBV-
151) research and development activities up to completion of IND-enabling studies. 

88  |  Collaboration Agreements

We have granted AbbVie an exclusive option, for a specified period following completion of IND-enabling studies, to obtain a 
worldwide, exclusive license to the ARGX-115 (ABBV-151) program to develop and commercialize products. Following the exercise 
of the option, AbbVie will assume certain development obligations, and will be solely responsible for all research, development and 
regulatory costs relating to the products. We received an upfront, non-refundable, non-creditable payment of $40.0 million (€35.1 
million based on the exchange rate in effect as of the date the payment was received) from AbbVie for the exclusive option to license 
ARGX-115 (ABBV-151). During the course of the collaboration, we achieved two pre-defined preclinical milestones, each of which 
triggered a $10.0 million payment (€8.9 million based on the exchange rate in effect as of the date the first pre-clinical milestone 
payment was received and €8.7 million based on the exchange rate in effect as of the date the second pre-clinical milestone payment 
was received). In addition, in March 2019 we have achieved the first pre-defined clinical milestone, triggering a $30 million payment.

In August 2018, AbbVie exercised its option to develop and commercialize of ARGX-115 (ABBV-151) and has now assumed certain 
development obligations, including being solely responsible for all research, development and regulatory costs relating to ARGX-
115 (ABBV-151)-based products. Subject to the continuing progress of ARGX-115 (ABBV-151) by AbbVie, we are eligible to receive 
development, regulatory and commercial milestone payments in aggregate amounts of up to $110.0 million, $190.0 million and 
$325.0 million, respectively, as well as tiered royalties on product sales at percentages ranging from the mid-single digits to the 
lower teens, subject to customary reductions. 

We have the right, on a product-by-product basis to co-promote ARGX-115 (ABBV-151)-based products in the European Economic 
Area and Switzerland and combine the product with our own future oncology programs. The co-promotion effort would be governed 
by a co-promotion agreement negotiated in good faith by the parties. 

Unless earlier terminated upon mutual agreement, for material breach or as otherwise specified in the agreement, the term of 
the option and license agreement ends, with respect to the ARGX-115 (ABBV-151) program, upon the earliest of (i) a technical 
failure of the IND-enabling studies which is outside of our control, (ii) AbbVie’s election to not exercise its option, or (iii) following 
AbbVie’s exercise of the option, fulfilment of all payment obligations under the agreement. AbbVie may terminate the agreement 
for any reason upon prior written notice to us. AbbVie’s royalty payment obligations expire, on a product-by-product and country-
by-country basis, on the date that is the later of (i) such time as there are no valid claims covering such product, (ii) expiration of 
regulatory or market exclusivity in respect of such product or (iii) 10 years after the first commercial sale of such product sold in 
that country under the agreement. 

3.6.3.  OUR COLLABORATION WIT H GE N OR B I O P HAR M A/B I R D RO CK B I O (FO R ARG X 109)

In October 2012, we entered into an exclusive license agreement with Bird Rock Bio, Inc. (formely known as RuiYi Inc. and Anaphore, 
Inc.), to develop and commercialize ARGX-109. In 2018, we and Bird Rock Bio mutually agreed to terminate this exclusive license 
agreement. Genor Biopharma, a sublicensee of Bird Rock Bio, will continue to develop ARGX-109 for the Chinese market. 

3.6.4.  OUR STRATEGI C PARTNERSHIP WI TH L EO P HAR M A (FOR ARG X-112)

In May 2015, we entered into a collaboration agreement with LEO Pharma A/S, or LEO Pharma, to develop and commercialize ARGX-
112. Under the terms of the collaboration, LEO Pharma funded more than half of all product development costs up to CTA approval 
of a first product in a Phase 1 clinical trial, with our share of such costs capped. Now that CTA approval of a first product in a Phase 1 
clinical trial has been received (in April 2018), LEO Pharma is solely responsible for funding the clinical development of the program. 

We received a non-refundable, non-creditable upfront payment from LEO Pharma of €3.0 million in cash. In February 2016, June 
2017 and April 2018, we achieved preclinical milestones under this collaboration for which we received milestone payments. Up 
through specified periods following the latest to occur of (i) submission of an application to commence a Phase 2b dose finding 
trial (or Phase 3 clinical trial if a Phase 2b is not conducted) or (ii) the availability of an International Preliminary Examination report 
for ARGX-112 patent rights after completion of a Phase 2a clinical trial, LEO Pharma may exercise an option to obtain an exclusive, 
worldwide license to further develop and commercialize products. Following the exercise of the option, LEO Pharma would assume 
full responsibility for the continued development, manufacture and commercialization of such product, subject to certain diligence 
obligations. If LEO Pharma elects to exercise this option, it must pay us an option fee. We are also eligible to receive additional 

Collaboration Agreements    |  89 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSdevelopment, regulatory and commercial milestone payments in aggregate amounts of up to €11.5 million, €6.0 million and €102.5 
million, respectively, as well as tiered royalties on product sales at percentages ranging from the low single digits to the low teens, 
subject to customary reductions. 

If LEO Pharma does not exercise its option prior to expiration of the applicable option period, if it does not meet certain development 
diligence obligations within a specified time, or if the agreement is terminated other than for reasons of our breach or insolvency, 
then we have the right to develop and commercialize ARGX-112 alone, subject to our obligation to pay LEO Pharma low-single digit 
percentage royalties on net sales of any product covered by any LEO Pharma patents, know-how or rights in research results gener-
ated under the collaboration. If the agreement is terminated for reasons of our breach or insolvency, rights to product candidates 
in development at the time of such termination will be allocated to the parties through a mechanism specified in the agreement. 

Unless earlier terminated upon mutual agreement, for material breach or as otherwise specified in the agreement, the term of 
the agreement ends upon the later of (i) the expiration of the option period, (ii) the expiration of the last license which has been 
granted under the agreement, and (iii) the fulfilment of all payment obligations which may arise under the agreement. LEO Pharma 
may terminate the agreement for any reason upon prior written notice to us. LEO Pharma’s royalty payment obligations expire, on a 
product-by-product and country-by-country basis, on the date that is the later of (i) such time as there are no valid claims covering 
such product, (ii) in major market countries in which no composition of matter patent has been issued covering such product, the 
expiration of the data exclusivity period or (iii) in countries that are not major market countries, a double-digit number of years 
after the first commercial sale of such product sold in that country under the agreement.

3.6.5.  OUR RESEARC H COLLABORATI ON W I TH S TAT EN (FO R ARG X-116)

In January 2015, we entered into a collaboration agreement with Staten Biotechnology B.V., or Staten, to develop and commercialize 
products in the area of dyslipidemia therapy. Under the collaboration agreement, the parties sought to discover and characterize 
antibodies against a human target with therapeutic relevance in the field of dyslipidemia and/or cardiovascular disease. The parties 
may also commence two further research programs for targets with therapeutic relevance in these areas. Each research program 
will last no more than 24 months from commencement unless the parties agree otherwise. The first research program under this 
agreement proceeded as planned and was extended to December 2017, with ARGX-116 identified as the initial product candidate. 
Staten exercised its exclusive option to license ARGX-116 in March 2017. Under the terms of the collaboration, the parties were and 
are jointly responsible for conducting research under a mutually agreed research plan, with Staten reimbursing us for all costs of 
carrying out our research responsibilities under each research program. Staten is also responsible for additional clinical development. 

On a research program-by-research program basis, up through a specified period within such research program, we have granted 
Staten an option to obtain an exclusive, worldwide, permanent license to research, develop and commercialize products identified 
in that program. If Staten elects to exercise this option for a product (as it has for ARGX-116), it would be obligated to pay us a 
percentage of any payments payable to or on behalf of Staten’s shareholders in the event of (i) a change of control of Staten, (ii) any 
licensing, sale, disposition or similar transaction relating to any such product, or (iii) otherwise from the research, development or 
commercialization of that product. This percentage varies by stage of development for an applicable product and ranges up to the 
low-twenties, subject to downward proportional adjustment in the event a portion of the proceeds from the applicable transaction 
does not include payment for the product candidate we developed with Staten. Staten has certain diligence obligations to develop 
and commercialize at least one product during the term of the agreement and must report on their progress in doing so on an 
annual basis. 

In December 2018, Staten announced that it had entered into a collaboration and exclusive option agreement with Novo Nordisk, 
to develop novel therapeutics for the treatment of hypertriglyceridemia. Specifically, Novo will provide research and development 
funding and support to Staten, to develop its lead asset STT-5058 (formerly ARGX-116) for the treatment of dyslipidemia. Novo has 
the right under the agreement to acquire Staten and gain worldwide rights to STT-5058. Staten and its shareholders will potentially 
receive signing and exercise fees, research and development funding, and milestone payments of up to 430 million Euro.

If Staten does not exercise its option with respect to a research program prior to expiration of the applicable option period, then 
we have the right to research, develop and commercialize product candidates in relation to the relevant target at our sole cost 
and expense. 

90  |  Collaboration Agreements

Unless earlier terminated upon mutual agreement, for material breach or as otherwise specified in the agreement, the collaboration 
term ends on the later of (i) January 2020, (ii) expiration of the last license granted by us under the agreement, (iii) expiration of last 
option period for Staten and (iv) fulfilment of all payment obligations which have arisen or may arise pursuant to the agreement. In 
addition, we may terminate the agreement in whole or with respect to a research program if no targets have been selected within 
24 months of the effective date of the agreement, other than the target selected for the ARGX-116 research program. 

3.6.6.  OUR STRATEGI C COLLABORATI O N W I TH S HI R E

In February 2012, we entered into a collaboration agreement with Shire AG (now known as Shire International GmbH), or Shire, 
to discover, develop and commercialize novel human therapeutic antibodies against up to three targets to address diverse, rare 
and unmet diseases. Under the terms of the collaboration, for any target selected for study under the collaboration, the parties 
worked together to conduct research and development through discovery of antibodies with certain specificity for and functional 
activity against those targets. 

Up through a specified period following completion of each study for a target, we have granted Shire an exclusive option to obtain 
all right, title and interest in any antibodies discovered under a study and to obtain an exclusive, worldwide license under our 
intellectual property which is necessary to further develop and commercialize products incorporating such antibodies. Following 
exercise of its exclusive option, Shire has certain diligence obligations to develop and commercialize at least one product. To exercise 
this option with respect to antibodies discovered against any of the three initial targets named in the agreement, Shire paid us a 
one-time option fee. 

In May 2014, we expanded the collaboration agreement to accommodate research and development of additional novel targets 
implicated in multiple disease areas to provide Shire with a sublicense under our license agreement with the University of Texas 
with respect to our NHance® and ABDEGTM engineering technologies and to provide an option to a sublicense to the POTELLIGENT® 
technology of BioWa, Inc. The initial three-year term of this expanded agreement expired on May 30, 2017, and Shire opted to 
extend the collaboration term for a further year until May 30, 2018, but no further beyond May 2018. 

Shire may exercise exclusive options to develop and commercialize programs arising under our expanded agreement, in which 
case an option fee is due on a per program basis. In July 2018, Shire exercised such an exclusive option to in-license an antibody 
discovered and developed using our licensed technologies, which exercise triggered a milestone payment by Shire to us, in an 
amount undisclosed due to contractual obligations of confidentiality.

In addition to option fees, Shire would also be obligated to pay us on a per-product basis upon achievement of specified devel-
opment, regulatory and commercial milestones and a percentage of net sales as a royalty. Milestones are paid on a first product 
per indication per study target basis, and we are eligible to receive payments in aggregate amounts of up to $3.8 million, $4.5 
million and $22.5 million, upon achievement of development, regulatory and commercial milestones, respectively, for a product 
generated against one of the three initial targets named in the 2012 agreement. For products generated against additional targets 
nominated under the 2014 agreement, development and regulatory milestone payments remain the same, and we are eligible to 
receive payments in aggregate amounts of up to $60.0 million for achievement of commercial milestones. The royalties payable to 
us are tiered, single digit and are subject to customary reductions. Through December 31, 2019, pursuant to the agreement Shire 
has paid us an aggregate total of (i) €3.4 million in upfront payments, (ii) €0.3 million in milestone payments and (iii) $12.6 million 
in research and development funding. In addition, Shire purchased 12.0 million of our ordinary shares in July 2014 by participating 
in our initial public offering on Euronext Brussels. 

If Shire does not exercise its option with respect to any discovered antibody within a specified period, then we are free to research, 
develop and commercialize antibodies in relation to the applicable study target, subject to negotiation of a license from Shire for 
the use of any antibodies that were discovered during the applicable study, or any Shire confidential information, Shire intellectual 
property or Shire’s interest in any joint intellectual property. If (a) Shire (i) does not exercise its option with respect to any discovered 
antibody, or (ii) exercises its option but later abandons development of such antibody or (iii) the agreement is terminated other than 
for our breach or insolvency, and (b) Shire is no longer pursuing a development program with respect to the applicable study target, 

Collaboration Agreements    |  91 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSthen we may elect to continue the development of such antibody at our sole cost and expense, subject to negotiation of a license 
from Shire under which Shire will receive either specified royalties, if we commercialize the program ourselves, or a percentage of 
sublicensing revenues, if the program is subsequently sublicensed to a third party. 

Unless earlier terminated upon mutual agreement, for material breach or as otherwise specified in the agreement, the collaboration 
term ends with the expiry of the last royalty term under the agreement. Each royalty term expires, on a product-by-product and 
country-by-country basis, on the date that is the later of (i) such time as there are no valid claims covering such product or (ii) 10 
years after the first commercial sale of such product sold in that country under the agreement. Shire may terminate the agreement 
for any reason upon prior written notice to us.

3.6.7.  LICENSE AGREEMENTS – GENER AL

We are a party to several license agreements under which we license patents, patent applications and other intellectual property to 
third parties. The licensed intellectual property covers some of our product candidates and some of the Fc engineering technologies 
that we use. Some of these licenses impose various diligence and financial payment obligations on us. We expect to continue to 
enter into these types of license agreements in the future.

3.6.8.  OU R EXCLUSI VE LICENSE WITH HALOZYM E (E N HAN ZE)

In February 2019, we entered into a license agreement with Halozyme Inc., or Halozyme, for the use of certain patents, materials 
and know-how owned by Halozyme and relating to its ENHANZE® Technology, for application in the field of prevention and treatment 
of human diseases. ENHANZE® Technology is referred to herein as ENHANZE. Under the terms of the license, we were granted 
exclusive rights to apply ENHANZE to biologic products against pre-specified targets, in order to research, develop and commercialize 
subcutaneous formulations of our therapeutic antibody-based product candidates.

Our first therapeutic target for which we have received an exclusive license from Halozyme is FcRn, which allows us to apply 
ENHANZE to efgartigimod and any other product candidates selective and specific for FcRn. Moreover, the breadth of our exclusive 
license to FcRn precludes either Halozyme itself or any of its current or future partners from utilizing ENHANZE in the context of 
an FcRn-targeted product. Our second therapeutic target for which we received an exclusive license from Halozyme is human 
complement factor C2 associated with the product candidate ARGX-117, which is being developed to treat severe autoimmune 
diseases. Under the license terms, we also have the right to nominate future targets - again for an exclusive ENHANZE license if the 
target in question has not already been licensed by Halozyme or is not already being pursued by Halozyme. From the effective date 
of the license agreement, we have a four-year period in which to conduct research and preclinical studies on other target-specific 
molecules in combination with ENHANZE and may nominate a maximum of one additional target we have not yet nominated for 
an exclusive commercial license during the four-year term. 

In return for the FcRn exclusive license, we have made a $30 million upfront payment to Halozyme. In return for the nomination 
of and exclusive license on C2 we made a $10 million milestone payment in May 2019. Upon nomination of any future target for 
an exclusive commercialization license and confirmation by Halozyme that such a license is available, we will pay $10 million to 
Halozyme per target. We will be obligated to pay clinical development, regulatory and commercial milestones totaling $160 million 
for the first product that uses ENHANZE and is specific for a given target. Throughout the term of the agreement, we must provide 
Halozyme on an annual basis a guidance forecast setting out all projected milestone payments for products for the following four 
calendar quarters. We are also obligated to pay Halozyme a percentage of net sales as a royalty of any licensed product that uses 
ENHANZE. This royalty varies with net sales volume, ranging from the low to mid-single digits, and it is reduced by a maximum of 
50% if following 10 years from the first commercial sale of the product in a country, the last valid claim within the licensed ENHANZE 
patent(s) expires. Throughout the term of the agreement, we must provide Halozyme on an annual basis an estimate of royalty 
payments anticipated for the following four calendar quarters. We have certain diligence requirements with respect to development 
and commercialization of product candidates, but we are not obligated to utilize ENHANZE for every product candidate directed 
to a given exclusive target(s). 

92  |  Collaboration Agreements

Under the terms of the license and subject to certain restrictions, we have the right to grant sublicenses to third parties both for 
research/preclinical work (for example, to subcontractors) and for development and commercialization. Halozyme has no rights 
to any of our current or future product candidates which use the ENHANZE technology. Halozyme provides dedicated specialist 
support to us which it has accrued over ten years of licensing ENHANZE to its collaborators.

We may terminate the license agreement at any time, either in its entirety or on a target-by-target basis, by sending Halozyme prior 
written notice. Absent early termination, the agreement will automatically expire upon the expiry of our royalty payment obligations 
under the agreement. In the event the agreement is terminated for any reason, the license granted to us would terminate but 
Halozyme would grant our sublicensees a direct license following such termination. In the event the agreement is terminated other 
than for our breach, we would retain the right to sell licensed products then on hand for a certain period of time post-termination.

As also set out in chapter 6 “Corporate Governance”, our non-executive director James M. Daly is also a non-executive member of 
the board of directors of Halozyme. Despite this, our entering into the license agreement with Halozyme was not a related party 
transaction in accordance with IAS 24 – Related Party Disclosures, since Mr. Daly, in his role as non-executive director, does not 
control or have significant influence over our company or Halozyme. Mr. Daly did not participate in any discussions and decision 
making relating to the Halozyme license agreement. Consequently, no further disclosures regarding Halozyme have been added in 
paragraph “Related Party Transactions”.

3.6.9.  OUR EXCLUSI VE LICENSE WITH AGO M AB (ARGX-114)

In March 2019, we entered into an exclusive license with AgomAb Therapeutics NV, or AgomAb, for the use of certain patents 
rights relating to our proprietary suite of technologies for the development and commercialization of a series of agonistic anti-MET 
SIMPLE Antibodies, including ARGX-114, an HFG-mimetic SIMPLE AntibodyTM directed against the MET receptor. AgomAb is required 
to use commercially reasonable efforts to develop and commercialize at least one licensed product. In connection with our entry 
into this agreement, we received a profit sharing certificate which entitles us to 20% of all distributions to AgomAb’s shareholders 
(which shall be reduced to 10% following the filing of an IND and is subject to further adjustment upon the occurrence of certain 
financings). Upon the occurrence of a qualified IPO of AgomAb, the profit sharing certificate will automatically be converted into an 
equivalent number of ordinary shares of AgomAb. This agreement is subject to mutual termination for material breach or insolvency 
and automatically expires upon the expiration of the last to expire of our licensed patent rights.

3.6.10.  OUR EXCLUSI VE LICENSE WITH B ROT EI O (ARGX-117)

In March 2017, we entered into a collaboration under our Innovative Access Program with Broteio Pharma B.V., or Broteio, to develop 
an antibody against a novel target in the complement cascade, ARGX-117. Under the terms of the agreement, we and Broteio 
jointly developed the complement-targeted antibody to seek to establish preclinical proof-of-concept using our proprietary suite 
of technologies. Upon successful completion of these studies, we exercised an exclusive option to license the program in March 
2018 and assumed responsibility for further development and commercialization. Under this agreement, we are obligated to make 
milestone payments upon the occurrence of certain development milestones (up to an aggregate of €4,000,000), commercialization 
milestones (up to an aggregate of €10,000,000) and pay tiered royalties on net sales in the low single digits. We may terminate this 
agreement for convenience upon 90 days prior written notice. This agreement is also subject to mutual termination for material 
breach or insolvency and automatically expires upon the expiration of our financial obligations thereunder.

3.6.11. OU R EXCLUSI VE LICENSE WITH V I B (ARG X-118)

In November 2016, we entered into a collaboration under our Innovative Access Program with VIB vzw, or VIB, an inflammation 
research center in Ghent, Brussels, to develop antibodies against Galectin-10, the protein of Charcot-Leyden Crystals, which play a 
major role in severe asthma and the persistence of mucus plugs, including ARGX-118. Under the terms of the agreement, we and 
VIB jointly developed antibodies against Galectin-10 using our proprietary suite of technologies. Upon successful completion of this 
initial research, we exercised an exclusive option to license the program and assumed responsibility for further development and 
commercialization. Under this agreement, including a November 2018 amendment, we are obligated to make milestone payments 
upon the occurrence of certain development milestones (up to an aggregate of €4,025,000), commercialization milestones (up to 

Collaboration Agreements    |  93 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSan aggregate of €11,000,000) and pay tiered royalties on net sales in the low single digits. We may terminate this agreement for 
convenience upon 90 days prior written notice. This agreement is also subject to mutual termination for material breach, insolvency 
or certain patent challenges and automatically expires upon the expiration of VIB’s licensed patent rights.

3.6.12.  OUR EXCLUSI VE LICENSE WITH T H E U N I V ER S I TY O F T EXAS (N HAN C E ® AN D AB DEG TM)

In February 2012, we entered into an exclusive license with The Board of Regents of The University of Texas System, or UoT, for use 
of certain patents rights relating to the NHance® platform, for any use worldwide. The agreement was amended on December 23, 
2014 to also include certain additional patent rights relating to the ABDEGTM platform. 

Upon commercialization of any of our products that use the in-licensed patent rights, we will be obligated to pay UoT a percentage of 
net sales as a royalty until the expiration of any patents covering the product. This royalty varies with net sales volume and is subject 
to an adjustment for royalties we receive from a sublicensee of our rights under this agreement, but in any event does not exceed 
1%. In addition, we must make annual license maintenance payments to UoT until termination of the agreement. We have assumed 
certain development and commercial milestone payment obligations and must report on our progress in achieving product sales on 
a quarterly basis. The maximum milestone payments we would be required to make is approximately $0.5 million in total. Through 
December 31, 2019, we have paid UoT an aggregate of $0.74 million, which includes reimbursement for UoT’s patent prosecution 
and maintenance costs and development milestones on products using the in-licensed patent rights. We also have certain diligence 
requirements with respect to development and commercialization of products which use the in-licensed patent rights. 

Under the terms of the license, we have the right to grant sublicenses to third parties, subject to certain restrictions. If we receive 
any non-royalty income in connection with such sublicenses, we must pay UoT a percentage of such income varying from low-middle 
single digits to middle-upper single digits depending on the nature of the sublicense. Such fees are waived if a sublicensee agrees 
to pay the milestone payments as set forth in our agreement with UoT. 

We may unilaterally terminate the license agreement for convenience upon prior written notice. Absent early termination, the 
agreement will automatically expire upon the expiration of all issued patents and filed patent applications within the patent rights 
covered by the agreement. Our royalty payment obligations expire, on a product-by-product and country-by-country basis, at such 
time as there are no valid claims covering such product.

3.6.13.  OUR NON-EXCLUSIVE LIC ENSE WIT H BI OWA (P OT EL L I GE N T®)

In October 2010, we entered into a non-exclusive license agreement with BioWa, Inc., or BioWa, for use of certain patents and 
know-how owned by BioWa and relating to its POTELLIGENT® Technology, for use in the field of prevention and treatment of human 
diseases. POTELLIGENT® Technology is referred to herein as POTELLIGENT®. Under the terms of the license, we are granted a non-ex-
clusive right to use POTELLIGENT® to research, develop and commercialize antibodies and products containing such antibodies using 
POTELLIGENT®. BioWa retains a right of first negotiation for the exclusive right to develop and commercialize, in certain countries 
only, any product we develop using POTELLIGENT®. We successfully applied POTELLIGENT® to cusatuzumab, an anti-CD70 mAb, and 
ARGX-111, an anti-c-Met mAb, under this license. 

Upon commercialization of our products developed using POTELLIGENT®, we will be obligated to pay BioWa a percentage of net sales 
of a licensed product as a royalty. This royalty varies with net sales volume, ranging in the low single digits, and it is reduced by half 
if during the following 10 years from the first commercial sale of the product in a country the last valid claim within the licensed 
patent(s) that covers the product expires or ends. In addition, we must make annual research license maintenance payments which 
cease with commencement of our royalty payments to BioWa. We have certain diligence requirements with respect to development 
and commercialization of products. We have also assumed certain development, regulatory and commercial milestone payment 
obligations and must report on our progress toward achieving these milestones on an annual basis. Milestones are to be paid on 
a commercial target-by-commercial target basis, and we are obligated to make milestone payments in aggregate amounts of up to 
$36.0 million per commercial target should we achieve annual global sales of over $1.0 billion. 

94  |  Collaboration Agreements

Under the terms of the license, we have the right to grant sublicenses to third parties, subject to certain restrictions. 

We may terminate the license agreement at any time by sending BioWa prior written notice. Absent early termination, the agree-
ment will automatically expire upon the expiry of our royalty obligations under the agreement. In the event the agreement is 
terminated for any reason, the license granted to us would terminate but BioWa would grant our sublicensees a direct license 
following such termination. In the event the agreement is terminated other than for our breach or insolvency, we would retain the 
right to sell licensed products then on hand for a certain period of time post-termination. 

3.6.14.  OUR NON-EXCLUSIVE LIC ENSES W I TH BI OWA AN D LO N Z A (P OT ELL I G EN T® CH OK1S V)

To scale up production of our product candidates cusatuzumab and ARGX-111 for clinical trial and commercial supply, we required a 
license to a GMP cell line in which POTELLIGENT® antibodies could be expressed. This cell line, POTELLIGENT® CHOK1SV, was jointly 
developed by BioWa and Lonza. In December 2013 and August 2014, respectively, we entered non-exclusive commercial license 
agreements for cusatuzumab and ARGX-111 with BioWa and Lonza Sales AG, or Lonza, for use of certain patents and know-how 
relating to the POTELLIGENT® CHOK1SV Technology, which is a combination of Lonza’s GS System and BioWa’s POTELLIGENT® 
Technology, for use in the field of prevention and treatment of human diseases. Under the terms of each commercial license, we 
received a non-exclusive right to research, develop and commercialize products containing an antibody generated specifically 
against a specific target using POTELLIGENT® CHOK1SV, namely the target CD70 in the case of cusatuzumab and c-Met in the case 
of ARGX-111. Both targets are designated as reserved targets under our 2010 license agreement with BioWa, which continues to 
govern our research, development and commercialization of products utilizing BioWa’s POTELLIGENT® Technology. Under the terms 
of each commercial license, BioWa retains a right of first negotiation for the exclusive right to develop and commercialize, in certain 
countries only, any product we develop using POTELLIGENT® CHOK1SV. This right of first negotiation is not applicable in cases where 
we intend to grant a global license to a third party to develop and commercialize a product - as was the case with our exclusive, 
global collaboration and license agreement for cusatuzumab with Cilag GmbH International, an affiliate of Janssen, which was 
entered into on December 3, 2018. BioWa retains a right of first negotiation for the exclusive right to develop and commercialize 
our anti-c-Met antibody ARGX-111, in certain countries only.

Upon commercialization of our products developed using POTELLIGENT® CHOK1SV, we will be obligated to pay both BioWa and 
Lonza a percentage of net sales as a royalty. We are required to pay a royalty to BioWa on net sales for any specific licensed product 
under only one license—either the POTELLIGENT® agreement or the POTELLIGENT® CHOK1SV agreement, but not both. The BioWa 
royalty is tiered, ranging in the low single digits and is reduced by half if during the following 10 years from the first commercial 
sale of the product in a country the last valid claim within the licensed BioWa patent(s) that covers the product expires or ends. 
The Lonza royalty varies based on whether the product is manufactured by Lonza, us or a third party, but in any event is in the 
low single digits and is reduced by half if during the following 10 years from the first commercial sale of the product in a country 
the last valid claim within the licensed Lonza patent(s) that covers the product expires or ends. In addition, we must make annual 
commercial license maintenance payments to BioWa on a per product basis which cease with commencement of payment of the 
BioWa royalty for the respective product, and annual payments to Lonza in the event that any product is manufactured by a party 
other than Lonza, us or one of our affiliates or strategic partners named in the agreement. 

We have assumed certain development, regulatory and commercial milestone payment obligations to both BioWa and Lonza and 
must report on our progress toward achieving these milestones on an annual basis. We are required to pay such milestones to 
BioWa under only one license—either the POTELLIGENT® agreement or the POTELLIGENT® CHOK1SV agreement, but not both. 
Payments related to the development and commercialization of cusatuzumab and ARGX-111 are foreseen under their respective 
POTELLIGENT® CHOK1SV agreements. Milestones are to be paid on a product-by-product basis, and we are obligated to make 
development, regulatory and commercial milestone payments to BioWa in aggregate amounts of up to $36.0 million per product 
should we achieve global annual sales of $1.0 billion. We are obligated to make development, regulatory and commercial milestone 
payments to Lonza in aggregate amounts of up to approximately £1.1 million per product, if such product is manufactured by Lonza, 
us or one of our affiliates or strategic partners, or £3.1 million per product, otherwise. Through December 31, 2019, we have paid 
BioWa an aggregate amount of $1.8 million, which includes target reservation fees and annual research license fees under our 
POTELLIGENT® agreement and commercial license fees and milestone payments under our POTELLIGENT® CHOK1SV agreement. 
Through December 31, 2019, we have paid Lonza an aggregate amount of £0.5 million, which includes milestone payments under 
our POTELLIGENT® CHOK1SV agreement.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSUnder the terms of both cusatuzumab and ARGX-111 commercial licenses, we have the right to grant sublicenses to certain 
pre-approved third parties, but otherwise must obtain BioWa and Lonza’s prior written consent. No prior written consent was 
required from either BioWa or Lonza for our exclusive global collaboration and license agreement for cusatuzumab with Cilag GmbH 
International, an affiliate of Janssen.

We may terminate the non-exclusive commercial license agreements at any time by sending BioWa and Lonza prior written notice. 
Absent early termination, the agreements will automatically expire upon the expiry of our royalty obligations under the respective 
agreement. In the event an agreement is terminated for any reason, the license granted to us would terminate but BioWa and Lonza 
would grant our sublicensees a direct license following such termination. In the event an agreement is terminated other than for our 
failure to make milestone or royalty payments, we would retain the right to sell the respective products then on hand for a certain 
period of time post-termination. Our royalty payment obligations expire, on a product-by-product and country-by-country basis, 
on the date that is the later of (i) 10 years after the first commercial sale of such product sold in that country under the agreement 
or (ii) such time as there are no valid claims covering such product. 

3.6.15. OUR COLLABORATION WIT H UCL AND SO PART EC (G AR P)

In January 2013, we entered into a collaboration and exclusive product license agreement with Université Catholique de Louvain, 
or UCL, and its technology transfer arm Sopartec S.A., or Sopartec, to discover and develop novel human therapeutic antibodies 
against GARP. Under the terms of the collaboration with UCL, each party was responsible for all of its own costs and in connection 
with the activities assigned to it under a mutually agreed research plan. 

In January 2015, we exercised the option we had been granted to enter into an exclusive, worldwide commercial license for use of 
certain GARP-related intellectual property rights owned by UCL and the Ludwig Institute for Cancer Research to further develop 
and commercialize licensed products, including the GARP-neutralizing antibody ARGX-115 (ABBV-151) which was discovered under 
the original collaboration. Upon the expiration of the agreement, this license would become a fully paid up, perpetual worldwide 
exclusive license under the GARP intellectual property for any purpose, subject to UCL’s retention of non-commercial research rights. 

Under the terms of the license, we obtained the right to grant sublicenses to third parties, subject to certain restrictions. From any 
income we receive in connection with these sublicenses, such as from our collaboration with AbbVie (see “Our Strategic Partnership 
with AbbVie” above), we must pay Sopartec a percentage of that income in the lower teen digit range. Royalty payment obligations 
expire on a product-by-product and country-by-country basis when there are no valid claims covering the ARGX-115 (ABBV-151) 
product. We also have certain diligence obligations with respect to development and commercialization of ARGX-115 (ABBV-151) 
products. Through December 31, 2019, we paid an aggregate amount of €6.8 million to Sopartec, as a result of the upfront and 
milestone payments we received from AbbVie.

3.7.  Regulatory Framework

3.7.1. 

INTRODUCTION

Government authorities in the United States, at the federal, state and local level, and in the European Union and other countries and 
jurisdictions, extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, 
packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, post-approval monitoring and reporting, 
and import and export of pharmaceutical products, including biological products. In addition, some jurisdictions regulate the pricing 
of pharmaceutical products. The processes for obtaining marketing approvals in the United States and in foreign countries and 
jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory authorities, require 
the expenditure of substantial time and financial resources.

96  |  Regulatory Framework

3.7.2.  LICENSURE AND REGULATION OF BI OLO GI C S I N T HE U N I TE D S TAT ES

In the United States, our product candidates are regulated as biological products, or biologics, under the Public Health Service Act, 
or PHSA, and the Federal Food, Drug, and Cosmetic Act, or FDCA, and their implementing regulations. The failure to comply with the 
applicable U.S. requirements at any time during the product development process, including nonclinical testing and clinical testing, 
the approval process or post-approval process, may subject an applicant to delays in the conduct of a study, regulatory review and 
approval, and/or administrative or judicial sanctions. These sanctions may include, but are not limited to, the FDA’s refusal to allow 
an applicant to proceed with clinical testing, refusal to approve pending applications, license suspension or revocation, withdrawal of 
an approval, warning or untitled letters, adverse publicity, product recalls, product seizures, total or partial suspension of production 
or distribution, injunctions, fines and civil or criminal investigations and penalties brought by the FDA or the Department of Justice 
or other governmental entities. 

An applicant seeking approval to market and distribute a new biologic in the United States generally must satisfactorily complete 
each of the following steps:

•  nonclinical laboratory tests, animal studies and formulation studies all performed in accordance with the FDA’s GLP regulations; 
submission to the FDA of an IND application for human clinical testing, which must become effective before human clinical 
• 
trials may begin; 

•  approval by an institutional review board, or IRB, representing each clinical site before each clinical trial may be initiated; 
•  performance of adequate and well-controlled human clinical trials to establish the safety, potency and purity of the product 

candidate for each proposed indication, in accordance with Good Clinical Practices, or GCP; 

•  preparation and submission to the FDA of a Biologic License Application, or BLA, for a biological product requesting marketing 
for one or more proposed indications, including submission of detailed information on the manufacture and composition of 
the product in clinical development and proposed labeling; 
review of the product by an FDA advisory committee, if applicable; 

• 
•  one or more FDA inspections of the manufacturing facility or facilities, including those of third parties, at which the product, or 
components thereof, are produced to assess compliance with current Good Manufacturing Practices, or cGMP, requirements and 
to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity; 

•  FDA audits of the clinical study sites to assure compliance with GCPs, and the integrity of clinical data in support of the BLA; 
•  payment of user fees and securing FDA approval of the BLA and licensure of the new biological product; and 
•  compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and 

Mitigation Strategy, or REMS, and any post-approval studies required by the FDA. 

Nonclinical Studies and Investigational New Drug Application
Before testing any biological product candidate in humans, the product candidate must undergo nonclinical testing. Nonclinical tests 
include laboratory evaluations of product chemistry, formulation and stability, as well as animal studies to evaluate the potential for 
activity and toxicity. The conduct of the nonclinical tests and formulation of the compounds for testing must comply with federal 
regulations and requirements. The results of the nonclinical tests, together with manufacturing information and analytical data, 
are submitted to the FDA as part of an Investigational New Drug, or IND, application. The IND automatically becomes effective 30 
days after receipt by the FDA, unless before that time the FDA raises concerns or questions about the product or conduct of the 
proposed clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks. In that case, 
the IND sponsor and the FDA must resolve any outstanding FDA concerns before the clinical trial can begin. 

As a result, submission of the IND may result in the FDA not allowing the trial to commence or on the terms originally specified by 
the sponsor in the IND. If the FDA raises concerns or questions either during this initial 30-day period, or at any time during the IND 
process, it may choose to impose a partial or complete clinical hold. This order issued by the FDA would delay either a proposed 
clinical study or cause suspension of an ongoing study, or in the case of a partial clinical hold place limitations on the conduct of 
the study such as duration of treatment, until all outstanding concerns have been adequately addressed and the FDA has notified 
the company that investigation may proceed and then only under terms authorized by the FDA. This could cause significant delays 
or difficulties in completing planned clinical trials in a timely manner. The FDA may impose clinical holds on a biological product 
candidate at any time before or during clinical trials due to safety concerns or non-compliance. 

Regulatory Framework    |  97 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSHuman Clinical Trials in Support of a BLA
Clinical trials involve the administration of the investigational product candidate to healthy volunteers or patients with the disease 
to be treated under the supervision of a qualified principal investigator in accordance with GCP requirements. Clinical trials are 
conducted under study protocols detailing, among other things, the objectives of the study, inclusion and exclusion criteria, the 
parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. A protocol for each clinical trial and any 
subsequent protocol amendments must be submitted to the FDA as part of the IND. 

A sponsor who wishes to conduct a clinical trial outside the United States may, but need not, obtain FDA authorization to conduct 
the clinical trial under an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the 
clinical trial to the FDA in support of the BLA so long as the clinical trial is well-designed and well-conducted in accordance with 
GCP, including review and approval by an independent ethics committee, and the FDA is able to validate the study data through 
an onsite inspection, if necessary. 

Further, each clinical trial must be reviewed and approved by an institutional review board, or IRB, either centrally or individually at 
each institution at which the clinical trial will be conducted. The IRB will consider, among other things, clinical trial design, patient 
informed consent, ethical factors and the safety of human subjects. An IRB must operate in compliance with FDA regulations. The 
FDA, IRB, or the clinical trial sponsor may suspend or discontinue a clinical trial at any time for various reasons, including a finding 
that the clinical trial is not being conducted in accordance with FDA requirements or the subjects or patients are being exposed 
to an unacceptable health risk. Clinical testing also must satisfy extensive GCP rules and the requirements for informed consent. 
Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, 
known as a data safety monitoring board or committee. This group may recommend continuation of the study as planned, changes 
in study conduct, or cessation of the study at designated check points based on access to certain data from the study. Information 
about certain clinical studies must be submitted within specific timeframes to the National Institutes of Health for public dissem-
ination at www.clinicaltrials.gov.

Clinical trials typically are conducted in three sequential phases, but the phases may overlap or be combined. Additional studies 
may be required after approval.

•  Phase 1 clinical trials are initially conducted in a limited population to test the product candidate for safety, including adverse 
effects, dose tolerance, absorption, metabolism, distribution, excretion and pharmacodynamics in healthy humans or, on occa-
sion, in patients, such as cancer patients. 

•  Phase 2 clinical trials are generally conducted in a limited patient population to identify possible adverse effects and safety 
risks, evaluate the efficacy of the product candidate for specific targeted indications and determine dose tolerance and optimal 
dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger Phase 
3 clinical trials. 

•  Phase 3 clinical trials proceed if the Phase 2 clinical trials demonstrate that a dose range of the product candidate is potentially 
effective and has an acceptable safety profile. Phase 3 clinical trials are undertaken within an expanded patient population to 
gather additional information about safety and effectiveness necessary to evaluate the overall benefit-risk relationship of the 
drug and to provide an adequate basis for physician labeling.

In some cases, the FDA may approve a BLA for a product candidate but require the sponsor to conduct additional clinical trials 
to further assess the product candidate’s safety and effectiveness after approval. Such post-approval trials are typically referred 
to as Phase 4 clinical trials. These studies are used to gain additional experience from the treatment of patients in the intended 
therapeutic indication and to document a clinical benefit in the case of biologics approved under accelerated approval regulations. 
If the FDA approves a product while a company has ongoing clinical trials that were not necessary for approval, a company may 
be able to use the data from these clinical trials to meet all or part of any Phase 4 clinical trial requirement or to request a change 
in the product labeling. Failure to exhibit due diligence with regard to conducting required Phase 4 clinical trials could result in 
withdrawal of approval for products. 

A drug being studied in clinical trials may be made available to individual patients in certain circumstances. Pursuant to the 21st 
Century Cures Act, as amended, the manufacturer of an investigational drug for a serious disease or condition is required to make 
available, such as by posting on its website, its policy on evaluating and responding to requests for individual patient access to such

investigational drug. This requirement applies on the earlier of the first initiation of a Phase 2 or Phase 3 trial of the investigational 
drug, or as applicable, 15 days after the drug receives a designation as a breakthrough therapy, fast track product, or regenerative 
advanced therapy.

Compliance with cGMP Requirements
Before approving a BLA, the FDA typically 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 are in full compliance with cGMP 
requirements and adequate to assure consistent production of the product within required specifications. The PHSA emphasizes the 
importance of manufacturing control for products like biologics whose attributes cannot be precisely defined. The manufacturing 
process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor 
must develop methods for testing the identity, strength, quality, potency, and purity of the final biological product. Additionally, 
appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the biological 
product candidate does not undergo unacceptable deterioration over its shelf life.

Manufacturers and others involved in the manufacture and distribution of products must also register their establishments with 
the FDA and certain state agencies. Both domestic and foreign manufacturing establishments must register and provide additional 
information to the FDA upon their initial participation in the manufacturing process. Any product manufactured by or imported 
from a facility that has not registered, whether foreign or domestic, is deemed misbranded under the FDCA. Establishments may 
be subject to periodic unannounced inspections by government authorities to ensure compliance with cGMPs and other laws. 
Manufacturers may have to provide, on request, electronic or physical records regarding their establishments. Delaying, denying, 
limiting, or refusing inspection by the FDA may lead to a product being deemed to be adulterated. 

Review and Approval of a BLA
The results of product candidate development, nonclinical testing and clinical trials, including negative or ambiguous results as well 
as positive findings, are submitted to the FDA as part of a BLA requesting a license to market the product. The BLA must contain 
extensive manufacturing information and detailed information on the composition of the product and proposed labeling as well 
as payment of a user fee. 

The FDA has 60 days after submission of the application to conduct an initial review to determine whether the BLA is sufficient to 
accept for filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. Once 
the submission has been accepted for filing, the FDA begins an indepth review of the application. Under the goals and policies 
agreed to by the FDA under the Prescription Drug User Fee Act, or the PDUFA, the FDA has ten months in which to complete its 
initial review of a standard application and respond to the applicant, and six months for a priority review of an application. The FDA 
does not always meet its PDUFA goal dates for standard and priority BLAs. The review process may often be significantly extended 
by FDA requests for additional information or clarification. The review process and the PDUFA goal date may be extended by three 
months if the FDA requests or if the applicant otherwise provides additional information or clarification regarding information 
already provided in the submission within the last three months before the PDUFA goal date. 

On the basis of the FDA’s evaluation of the application and accompanying information, including the results of the inspection of 
the manufacturing facilities and any FDA audits of clinical trial sites to assure compliance with GCPs, the FDA may issue an approval 
letter, denial letter, or a complete response letter. An approval letter authorizes commercial marketing of the product with specific 
prescribing information for specific indications. Under the PHSA, the FDA may approve a BLA if it determines that the product is safe, 
pure and potent and the facility where the product will be manufactured meets standards designed to ensure that it continues to 
be safe, pure and potent. If the application is not approved, the FDA may issue a complete response letter, which will contain the 
conditions that must be met in order to secure final approval of the application, and when possible will outline recommended actions 
the sponsor might take to obtain approval of the application. Sponsors that receive a complete response letter may submit to the 
FDA information that represents a complete response to the issues identified by the FDA or withdraw the application or request a 
hearing. The FDA will not approve an application until issues identified in the complete response letter have been addressed. The 
FDA issues a denial letter if it determines that the establishment or product does not meet the agency’s requirements. 

Regulatory Framework    |  99 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSThe FDA may also refer the application to an advisory committee for review, evaluation and recommendation as to whether the 
application should be approved. In particular, the FDA may refer applications for novel biological products or biological products that 
present difficult questions of safety or efficacy to an advisory committee. Typically, an advisory committee is a panel of independent 
experts, including clinicians and other scientific experts, that reviews, evaluates and provides 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. 

If the FDA approves a new product, it may limit the approved indications for use of the product. It may also require that contra-
indications, warnings or precautions be included in the product labeling. In addition, the FDA may call for post-approval studies, 
including Phase 4 clinical trials, to further assess the product’s safety after approval. The agency may also require testing and 
surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions 
or other risk management mechanisms, including REMS, to help ensure that the benefits of the product outweigh the potential 
risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, 
or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only 
under certain circumstances, special monitoring and the use of patent registries. The FDA may prevent or limit further marketing 
of a product based on the results of post-market studies or surveillance programs. After approval, many types of changes to the 
approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further 
testing requirements and FDA review and approval. 

Fast Track, Breakthrough Therapy and Priority Review Designations
The FDA is authorized to designate certain products for expedited review if they are intended to address an unmet medical need 
in the treatment of a serious or life-threatening disease or condition. These programs are referred to as fast track designation, 
breakthrough therapy designation and priority review designation. 

The FDA may designate a product for fast track review if it is intended, whether alone or in combination with one or more other 
products, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet 
medical needs for such a disease or condition. For fast track products, sponsors may have greater interactions with the FDA and the 
FDA may initiate review of sections of a fast track product’s application before the application is complete. This rolling review may be 
available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a fast track product may 
be effective. The sponsor must also provide, and the FDA must approve, a schedule for the submission of the remaining information 
and the sponsor must pay applicable user fees. However, the FDA’s time period goal for reviewing a fast track application does not 
begin until the last section of the application is submitted. Fast track designation may be withdrawn by the FDA if the FDA believes 
that the designation is no longer supported by data emerging in the clinical trial process. 

A product may be designated as a breakthrough therapy if it is intended, either alone or in combination with one or more other 
products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may 
demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial 
treatment effects observed early in clinical development. The FDA may take certain actions with respect to breakthrough therapies, 
including holding meetings with the sponsor throughout the development process; providing timely advice to the product sponsor 
regarding development and approval; involving more senior staff in the review process; assigning a cross-disciplinary project lead 
for the review team; and taking other steps to design the clinical trials in an efficient manner. 

The FDA may designate a product for priority review if it is a product that treats a serious condition and, if approved, would provide 
a significant improvement in safety or effectiveness. The FDA determines, on a case-by-case basis, whether the proposed product 
represents a significant improvement when compared with other available therapies. Significant improvement may be illustrated 
by evidence of increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting 
product reaction, documented enhancement of patient compliance that may lead to improvement in serious outcomes and evidence 
of safety and effectiveness in a new subpopulation. A priority designation is intended to direct overall attention and resources to 
the evaluation of such applications, and to shorten the FDA’s goal for taking action on a marketing application from 10 months to 
six months.

Accelerated Approval Pathway
The FDA may grant accelerated approval to a product for a serious or life-threatening condition that provides meaningful therapeutic 
advantage to patients over existing treatments based upon a determination that the product has an effect on a surrogate endpoint 
that is reasonably likely to predict clinical benefit. The FDA may also grant accelerated approval for such a condition when the 
product has an effect on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or 
mortality, or IMM, and that is reasonably likely to predict an effect on IMM or other clinical benefit, taking into account the severity, 
rarity, or prevalence of the condition and the availability or lack of alternative treatments. Products granted accelerated approval 
must meet the same statutory standards for safety and effectiveness as those granted traditional approval. 

For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, 
physical sign, or other measure that is thought to predict clinical benefit but is not itself a measure of clinical benefit. Surrogate 
endpoints can often be measured more easily or more rapidly than clinical endpoints. An intermediate clinical endpoint is a measure-
ment of a therapeutic effect that is considered reasonably likely to predict the clinical benefit of a product, such as an effect on 
IMM. The FDA has limited experience with accelerated approvals based on intermediate clinical endpoints, but has indicated that 
such endpoints generally may support accelerated approval where the therapeutic effect measured by the endpoint is not itself a 
clinical benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to 
predict the ultimate clinical benefit of a product. 

The accelerated approval pathway is most often used in settings in which the course of a disease is long and an extended period of 
time is required to measure the intended clinical benefit of a product, even if the effect on the surrogate or intermediate clinical 
endpoint occurs rapidly. Thus, accelerated approval has been used extensively in the development and approval of products for 
treatment of a variety of cancers in which the goal of therapy is generally to improve survival or decrease morbidity and the duration 
of the typical disease course requires lengthy and sometimes large trials to demonstrate a clinical or survival benefit. 

The accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional 
post-approval confirmatory studies to verify and describe the product’s clinical benefit. As a result, a product 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, would allow the FDA to withdraw the product from the market on an expedited basis. All 
promotional materials for product candidates approved under accelerated regulations are subject to prior review by the FDA. 

Post-Approval Regulation
If regulatory approval for marketing of a product or new indication for an existing product is obtained, the sponsor will be required 
to comply with all post-approval regulatory requirements as well as any post-approval requirements that the FDA has imposed 
as part of the approval process. The sponsor will be required to report certain adverse reactions and production problems to the 
FDA, provide updated safety and efficacy information and comply with requirements concerning advertising and promotional 
labeling. Manufacturers and certain of their subcontractors are required to register their establishments with the FDA and certain 
state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with 
ongoing regulatory requirements, including cGMP regulations, which impose certain procedural and documentation requirements 
upon manufacturers. Accordingly, the sponsor and its third-party manufacturers must continue to expend time, money and effort 
in the areas of production and quality control to maintain compliance with cGMP regulations and other regulatory requirements. 

A biological product may also be subject to official lot release, meaning that the manufacturer is required to perform certain tests 
on each lot of the product before it is released for distribution. If the product is subject to official lot release, the manufacturer must 
submit samples of each lot, together with a release protocol showing a summary of the history of manufacture of the lot and the 
results of all of the manufacturer’s tests performed on the lot, to the FDA. The FDA may in addition perform certain confirmatory 
tests on lots of some products before releasing the lots for distribution. Finally, the FDA will conduct laboratory research related 
to the safety, purity, potency and effectiveness of pharmaceutical products. 

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is 
not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with 
a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply 

Regulatory Framework    |  101 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSwith regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-
market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. 
FDA also has authority to require post-market studies, in certain circumstances, on reduced effectiveness of a product and may 
require labeling changes related to new reduced effectiveness information. Other potential consequences for a failure to maintain 
regulatory compliance include, among other things:

• 

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product 
recalls; 

•  fines, untitled letters or warning letters or holds on post-approval clinical trials; 
• 

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of 
product license approvals; 

•  product seizure or detention, or refusal to permit the import or export of products; or 
• 

injunctions or the imposition of civil or criminal penalties. 

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Pharmaceutical 
products may be promoted only for the approved indications and in accordance with the provisions of the approved label. The 
FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that 
is found to have improperly promoted off-label uses may be subject to significant liability.

Orphan Drug Designation
Orphan drug designation in the United States is designed to encourage sponsors to develop products intended for rare diseases 
or conditions. In the United States, a rare disease or condition is statutorily defined as a condition that affects fewer than 200,000 
individuals in the United States or that affects more than 200,000 individuals in the United States and for which there is no reason-
able expectation that the cost of developing and making available the product for the disease or condition will be recovered from 
sales of the product in the United States. 

Orphan drug designation qualifies a company for tax credits and market exclusivity for seven years following the date of the 
product’s marketing approval if granted by the FDA. An application for designation as an orphan product can be made any time 
prior to the filing of an application for approval to market the product. A product becomes an orphan when it receives orphan drug 
designation from the Office of Orphan Products Development, or OOPD, at the FDA based on an acceptable confidential request 
made under the regulatory provisions. The product must then go through the review and approval process like any other product 
in order to be marketed.

A sponsor may request orphan drug designation of a previously unapproved product or new orphan indication for an already 
marketed product. In addition, a sponsor of a product that is otherwise the same product as an already approved orphan drug 
may seek and obtain orphan drug designation for the subsequent product for the same rare disease or condition if it can present a 
plausible hypothesis that its product may be clinically superior to the first drug. More than one sponsor may receive orphan drug 
designation for the same product for the same rare disease or condition, but each sponsor seeking orphan drug designation must 
file a complete request for designation. 

The period of exclusivity begins on the date that the marketing application is approved by the FDA and applies only to the indication 
for which the product has been designated. The FDA may approve a second application for the same product for a different use or 
a second application for a clinically superior version of the product for the same use. The FDA cannot, however, approve the same 
product made by another manufacturer for the same indication during the market exclusivity period unless it has the consent of 
the sponsor or the sponsor is unable to provide sufficient quantities. 

Pediatric Studies and Exclusivity
Under the Pediatric Research Equity Act of 2003, as amended, a BLA or supplement thereto must contain data that are adequate 
to assess the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations, and to 
support dosing and administration for each pediatric subpopulation for which the product is safe and effective. Sponsors must also 
submit pediatric study plans prior to the assessment data. Those plans must contain an outline of the proposed pediatric study or 

102  |  Regulatory Framework

studies the applicant plans to conduct, including study objectives and design, any deferral or waiver requests and other information 
required by regulation. The applicant, the FDA, and the FDA’s internal review committee must then review the information submitted, 
consult with each other and agree upon a final plan. The FDA or the applicant may request an amendment to the plan at any time. 

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. Generally, the 
pediatric data requirements do not apply to products with orphan designation. 

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attach-
ment of an additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non-patent 
and orphan exclusivity. This six-month exclusivity may be granted if a BLA sponsor submits pediatric data that fairly respond to a 
written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population 
studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports 
of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or 
regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term 
extension, but it effectively extends the regulatory period during which the FDA cannot approve another application. 

Biosimilars and Exclusivity
The Biologics Price Competition and Innovation Act, or BPCIA, established a regulatory scheme authorizing the FDA to approve 
biosimilars and interchangeable biosimilars. To date, while biosimilar products have been approved by the FDA for use in the United 
States, no interchangeable biosimilars have been approved. 

Under the BPCIA, a manufacturer may submit an application for licensure of a biologic product that is “biosimilar to” or “inter-
changeable with” a previously approved biological product or “reference product.” For the FDA to approve a biosimilar product, 
it must find that there are no clinically meaningful differences between the reference product and proposed biosimilar product in 
terms of safety, purity and potency. For the FDA to approve a biosimilar product as interchangeable with a reference product, the 
agency must find that the biosimilar product can be expected to produce the same clinical results as the reference product, and (for 
products administered multiple times) that the biologic and the reference biologic may be switched after one has been previously 
administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. 

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date 
of approval of the reference product. The FDA may not approve a biosimilar product until 12 years from the date on which the 
reference product was approved. Even if a product is considered to be a reference product eligible for exclusivity, another company 
could market a competing version of that product if the FDA approves a full BLA for such product containing the sponsor’s own 
nonclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of their 
product. However, to rely on such exclusivities for establishing or protecting our market position is not without risk, as such laws are 
subject to changes by the legislature. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable 
products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted 
by pharmacies, which are governed by state pharmacy law.

EUROPEAN UNION

In order to market any product outside of the United States, a company also must comply with numerous and varying regulatory 
requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical 
trials, marketing authorization, commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, 
an applicant will need to obtain the necessary approvals by the comparable foreign regulatory authorities before it can initiate 
clinical trials or marketing of the product in those countries or jurisdictions. Specifically, the process governing approval of medic-
inal products in the European Union generally follows the same lines as in the United States. It entails satisfactory completion of 
pharmaceutical development, nonclinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy 
of the medicinal product for each proposed indication. It also requires the submission to relevant competent authorities for clinical 

Regulatory Framework    |  103 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESStrials authorization and to the EMA or to competent authorities in European Union Member States for a marketing authorization 
application, or MAA, and granting of a marketing authorization by these authorities before the product can be marketed and sold 
in the European Union.

Clinical Trial Approval
Pursuant to the currently applicable Clinical Trials Directive 2001/20/EC and the Directive 2005/28/EC on GCP, a system for the 
approval of clinical trials in the European Union has been implemented through national legislation of the member states. Under 
this system, an applicant must obtain approval from the competent national authority of a European Union member state in which 
the clinical trial is to be conducted or in multiple member states if the clinical trial is to be conducted in a number of member states. 
Furthermore, the applicant may only start a clinical trial at a specific study site after the independent ethics committee has issued 
a favorable opinion. The clinical trial application, or CTA, must be accompanied by an investigational medicinal product dossier 
with supporting information prescribed by Directive 2001/20/EC and Directive 2005/28/EC and corresponding national laws of the 
member states and further detailed in applicable guidance documents. 

In April 2014, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which is set to replace the current 
Clinical Trials Directive 2001/20/EC. It is expected that the new Clinical Trials Regulation will enter into force in 2020 with a three-
year transition period. It will overhaul the current system of approvals for clinical trials in the European Union. Specifically, the 
new regulation, which will be directly applicable in all member states, aims at simplifying and streamlining the approval of clinical 
trials in the European Union. For instance, the new Clinical Trials Regulation provides for a streamlined application procedure via 
a single-entry point and strictly defined deadlines for the assessment of clinical trial applications. 

Orphan Drug Designation and Exclusivity
Regulation (EC) No. 141/2000 and Regulation (EC) No. 847/2000 provide that a product can be designated as an orphan drug by the 
European Commission if its sponsor can establish: that the product is intended for the diagnosis, prevention or treatment of (1) a 
life-threatening or chronically debilitating condition affecting not more than five in ten thousand persons in the European Union 
when the application is made, or (2) a life-threatening, seriously debilitating or serious and chronic condition in the European Union 
and that without incentives it is unlikely that the marketing of the drug in the European Union would generate sufficient return to 
justify the necessary investment. For either of these conditions, the applicant must demonstrate that there exists no satisfactory 
method of diagnosis, prevention, or treatment of the condition in question that has been authorized in the European Union or, if 
such method exists, the drug has to be of significant benefit compared to products available for the condition. 

An orphan drug designation provides a number of benefits, including fee reductions, regulatory assistance and the possibility to 
apply for a centralized European Union marketing authorization. Marketing authorization for an orphan drug leads to a ten-year 
period of market exclusivity. During this market exclusivity period, neither the EMA nor the European Commission or the member 
states can accept an application or grant a marketing authorization for a “similar medicinal product.” A “similar medicinal product” 
is defined as a medicinal product containing a similar active substance or substances as contained in an authorized orphan medicinal 
product, and which is intended for the same therapeutic indication. The market exclusivity period for the authorized therapeutic 
indication may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets 
the criteria for orphan drug designation because, for example, the product is sufficiently profitable not to justify market exclusivity. 

Marketing Authorization
To obtain a marketing authorization for a product under the European Union regulatory system, an applicant must submit an MAA, 
either to EMA using the centralized procedure or to competent authorities in European Union Member States using the other 
procedures (decentralized procedure, national procedure, or mutual recognition procedure). A marketing authorization may be 
granted only to an applicant established in the European Union. Regulation (EC) No. 1901/2006 provides that prior to obtaining 
a marketing authorization in the European Union, an applicant must demonstrate compliance with all measures included in an 
EMA-approved Pediatric Investigation Plan, or PIP, covering all subsets of the pediatric population, unless the EMA has granted a 
product-specific waiver, class waiver, or a deferral for one or more of the measures included in the PIP. 

The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid 
for all European Union member states. Pursuant to Regulation (EC) No. 726/2004, the centralized procedure is compulsory for 
specific products, including for medicines produced by certain biotechnological processes, products designated as orphan medicinal 

104  |  Regulatory Framework

products, advanced therapy products and products with a new active substance indicated for the treatment of certain diseases, 
including products for the treatment of cancer and auto-immune diseases. For products with a new active substance indicated for 
the treatment of other diseases and products that are highly innovative or for which the centralized procedure is in the interest of 
public health, the centralized procedure may be optional. 

Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the EMA 
is responsible for conducting the assessment of a product to define its risk/benefit profile. Under the centralized procedure, the 
maximum timeframe for the evaluation of an MAA is 210 days, excluding clock stops when additional information or written or oral 
explanation is to be provided by the applicant in response to questions of the CHMP. Accelerated evaluation may be granted by the 
CHMP in exceptional cases, when a medicinal product is of major interest from the point of view of public health and, in particular, 
from the viewpoint of therapeutic innovation. If the CHMP accepts such a request, the time limit of 210 days will be reduced to 
150 days, but it is possible that the CHMP may revert to the standard time limit for the centralized procedure if it determines that 
it is no longer appropriate to conduct an accelerated assessment. 

Periods of Authorization and Renewals
A marketing authorization is valid for five years, in principle, and it may be renewed after five years on the basis of a reevaluation 
of the risk benefit balance by the EMA or by the competent authority of the authorizing member state. To that end, the marketing 
authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, 
safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months before 
the marketing authorization ceases to be valid. Once renewed, the marketing authorization is valid for an unlimited period, unless 
the European Commission or the competent authority decides, on justified grounds relating to pharmacovigilance, to proceed 
with one additional five-year renewal period. Any authorization that is not followed by the placement of the drug on the European 
Union market (in the case of the centralized procedure) or on the market of the authorizing member state within three years after 
authorization ceases to be valid.

Regulatory Requirements after Marketing Authorization
Following approval, the holder of the marketing authorization is required to comply with a range of requirements applicable to 
the manufacturing, marketing, promotion and sale of the medicinal product. These include compliance with the European Union’s 
stringent pharmacovigilance or safety reporting rules, pursuant to which post-authorization studies and additional monitoring 
obligations can be imposed. In addition, the manufacturing of authorized products, for which a separate manufacturer’s license is 
mandatory, must also be conducted in strict compliance with the EMA’s GMP requirements and comparable requirements of other 
regulatory bodies in the European Union, which mandate the methods, facilities and controls used in manufacturing, processing 
and packing of drugs to assure their safety and identity. Finally, the marketing and promotion of authorized products, including 
industry-sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or the general 
public, are strictly regulated in the European Union under Directive 2001/83EC, as amended.

3.7.4.  COVERAGE, PRI CI NG AND REIMB U R SEM E N T

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we may obtain 
regulatory approval. Even if our product candidates are approved for marketing, sales of such product candidates will depend, in 
part, on the extent to which third-party payors, including government health programs in the United States (such as Medicare and 
Medicaid), commercial health insurers, and managed care organizations, provide coverage and establish adequate reimbursement 
levels for such product candidates. Moreover, increasing efforts by governmental and third-party payors in the European Union, 
the United States and other markets to cap or reduce healthcare costs may cause such organizations to limit both coverage and 
the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our 
product candidates. 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 and surgical procedures and other 
treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. 

Regulatory Framework    |  105 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSIn the United States and markets in other countries, third-party payors, including private and governmental payors, such as the 
Medicare and Medicaid programs, play an important role in determining the extent to which new drugs and biologics will be covered 
and patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on 
third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use any product candidates 
we may develop unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of such 
product candidates. The Medicare and Medicaid programs increasingly are used as models for how private payors and other 
governmental payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may 
require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse health care providers 
who use such therapies. 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. The process for determining whether a payor will provide coverage for a product may 
be separate from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is 
approved. Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of 
medical products and services and imposing controls to manage costs, especially drugs when an equivalent generic drug or a less 
expensive therapy is available. It is possible that a third-party payor may consider our product candidate and other therapies as 
substitutable and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or improved 
convenience of administration with our product candidate, pricing of existing drugs may limit the amount we will be able to charge 
for our product candidate. These payors may deny or revoke the reimbursement status of a given drug product or establish prices 
for new or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment 
in product development. If reimbursement is not available or is available only at limited levels, we may not be able to successfully 
commercialize our product candidates and may not be able to obtain a satisfactory financial return on products that we may develop. 
Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include 
all of the approved products for a particular indication. 

In order to secure coverage and reimbursement for any product that might be approved for sale, we may need to conduct expen-
sive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, and the 
cost of these studies would be in addition to the costs required to obtain FDA or other comparable marketing approvals. Even 
after pharmacogenomic studies are conducted, product candidates may not be considered medically necessary or cost-effective. 
A decision by a third-party payor not to cover any product candidates we may develop could reduce physician utilization of such 
product candidates once approved and have a material adverse effect on our sales, results of operations and financial condition. 
Additionally, a payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be 
approved. For example, the payor may require co-payments that patients find unacceptably high. Further, one payor’s determination 
to provide coverage for a product does not assure that other payors will also provide coverage and reimbursement for the product, 
and the level of coverage and reimbursement can differ significantly from payor to payor. Third-party reimbursement and coverage 
may not be adequate to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product 
development. The insurance coverage and reimbursement status of newly approved products for orphan diseases is particularly 
uncertain, and failure to obtain or maintain adequate coverage and reimbursement for any such product candidates could limit 
our ability to generate revenue. 

The containment of healthcare costs also has become a priority of U.S. federal, state and international governments and the prices 
of pharmaceuticals have been a focus in this effort. Governments have shown significant interest in implementing cost-containment 
programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption 
of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and 
measures, could further limit our potential revenue from the sale of any products for which we may obtain approval. Coverage poli-
cies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained 
for one or more of our products for which we or our collaborators receive marketing approval, less favorable coverage policies and 
reimbursement rates may be implemented in the future. Obtaining and maintaining reimbursement status is time-consuming and 
costly. No uniform policy for coverage and reimbursement for drug products exists among third-party payors in the United States. 
Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage 
determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support 
for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied 
consistently or obtained in the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in 
some cases at short notice, and we believe that changes in these rules and regulations are likely.

106  |  Regulatory Framework

Outside the United States, we will face challenges in ensuring obtaining adequate coverage and payment for any product candidates 
we may develop. Pricing of prescription pharmaceuticals is subject to governmental control in many countries. Pricing negotiations 
with governmental authorities can extend well beyond the receipt of regulatory marketing approval for a product and may require 
us to conduct a clinical trial that compares the effectiveness of any product candidates we may develop to other available therapies 
to support cost-effectiveness. The conduct of such a clinical trial could be expensive, involve additional risk and result in delays in 
our commercialization efforts. 

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 (so called 
health technology assessments, or HTAs) in order to obtain reimbursement or pricing approval. For example, the European Union 
provides options for its member states to restrict the range of products for which their national health insurance systems provide 
reimbursement and to control the prices of medicinal products for human use. European Union member states may approve a 
specific price for a product or may instead adopt a system of direct or indirect controls on the profitability of the company placing 
the product on the market. Other member states allow companies to fix their own prices for products but monitor and control 
prescription volumes and issue guidance to physicians to limit prescriptions. Recently, many countries in the European Union have 
increased the amount of discounts required on pharmaceuticals and these efforts could continue as countries attempt to manage 
healthcare expenditures, especially in light of the severe fiscal and debt crises experienced by many countries in the European 
Union. The downward pressure on health care costs in general, particularly prescription products, has become intense. As a result, 
increasingly high barriers are being erected to the entry of new products. Political, economic and regulatory developments may 
further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference 
pricing used by various European Union member states and parallel trade (arbitrage between low-priced and high-priced member 
states) can further reduce prices. Special pricing and reimbursement rules may apply to orphan drugs. Inclusion of orphan drugs 
in reimbursement systems tend to focus on the medical usefulness, need, quality and economic benefits to patients and the 
healthcare system as for any drug. Acceptance of any medicinal product for reimbursement may come with cost, use and often 
volume restrictions, which again can vary by country. In addition, results-based rules of reimbursement may apply. There can be no 
assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable 
reimbursement and pricing arrangements for any of our products, if approved in those countries.

Outside the United States, international operations are generally subject to extensive governmental price controls and other market 
regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe, Canada and other countries has and 
will continue to put pressure on the pricing and usage of our product candidates. In many countries, the prices of medical products 
are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their 
own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in 
pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside 
the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient 
to generate commercially reasonable revenue and profits. 

The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing 
and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National 
governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing 
and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most European Union 
member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. 
Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop and market products, 
this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect 
our ability to commercialize any products for which we obtain marketing approval.

3.7.5.  HEALTHCARE LAW AN D REGULATI ON

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of pharmaceutical products 
that are granted marketing approval. Our current and future arrangements with providers, researchers, consultants, third-party 
payors and customers are subject to broadly applicable federal and state fraud and abuse, anti-kickback, false claims, transparency 

Regulatory Framework    |  107 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSand patient privacy laws and regulations and other healthcare laws and regulations that may constrain our business and/or financial 
arrangements. Restrictions under applicable federal and state healthcare laws and regulations include, without limitation, the 
following:

• 

• 

• 

the U.S. federal Anti-Kickback Statute, or AKS, which prohibits, among other things, persons and entities from knowingly and 
willfully soliciting, receiving, offering, or paying remuneration, directly or indirectly, in cash or in kind, to induce or reward 
either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment 
may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid. . This statute has been 
interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and 
formulary managers on the other. A person or entity can be found guilty of violating the AKS without actual knowledge of the 
statute or specific intent to violate it. In addition, the government may assert that a claim including items or services resulting 
from a violation of the AKS constitutes a false or fraudulent claim for purposes of the federal False Claims Act or federal civil 
money penalties statute. Violations of the AKS carry potentially significant civil and criminal penalties, including imprisonment, 
fines, administrative civil monetary penalties, and exclusion from participation in federal healthcare programs; 
the U.S. federal false claims and civil monetary penalties laws, including the civil False Claims Act and federal civil monetary 
penalty laws, which, among other things, impose criminal and civil penalties, including through civil whistleblower or qui tam 
actions, against individuals or entities for knowingly presenting, or causing to be presented, to the U.S. federal government, 
claims for payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false 
record or statement material to a false or fraudulent claim or obligation to pay or transmit money to the federal government, 
or from knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. federal 
government. In addition, the government may assert that a claim including items and services resulting from a violation of the 
U.S. federal Anti Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act. Manufacturers 
can be held liable under the False Claims Act 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 False Claims Act also permits a private individual acting as 
a “whistleblower” to bring qui tam actions on behalf of the federal government alleging violations of the False Claims Act and 
to share in any monetary recovery. When an entity is determined to have violated the federal civil False Claims Act, the govern-
ment may impose civil fines and penalties for each false claim, plus treble damages, and exclude the entity from participation 
in Medicare, Medicaid and other federal healthcare programs;
the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability 
for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare 
benefit program, or obtaining by means of false or fraudulent pretenses, representations, or promises, any of the money or 
property owned by, or under the custody or control of, any healthcare benefit program, regardless of the pay (e.g., public or 
private) or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement, 
in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters; similar 
to the U.S. federal Anti Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific 
intent to violate it in order to have committed a violation;

•  HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and its 
implementing regulations, and as amended again by the Omnibus Rule in 2013, , which imposes certain obligations, including 
mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable 
health information without appropriate authorization by covered entities subject to the Final HIPAA Omnibus Rule, i.e. certain 
covered health plans, healthcare clearinghouses and healthcare providers, as well as their business associates, those indepen-
dent contractors or agents of covered entities that perform certain services for or on their behalf involving the use or disclosure 
of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to 
make civil and criminal penalties directly applicable to business associates and possibly other persons, and gave state attorneys 
general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and 
seek attorneys’ fees and costs associated with pursuing federal civil actions;
the U.S. Federal Food, Drug and Cosmetic Act, which prohibits, among other things, the adulteration or misbranding of drugs, 
biologics and medical devices; 
the federal transparency requirements known as the federal Physician Payments Sunshine Act, under the Patient Protection 
and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, collectively the ACA, which 
requires certain manufacturers of drugs, devices, biologics and medical supplies to report annually to the Centers for Medicare 
& Medicaid Services, or CMS, within the U.S. Department of Health and Human Services, information related to payments and 

• 

• 

108  |  Regulatory Framework

other transfers of value made by that entity to physicians (currently defined to include doctors, dentists, optometrists, podiatrists 
and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate 
family members. Failure to submit required information may result in civil monetary penalties for all payments, transfers of 
value or ownership or investment interests that are not timely, accurately, and completely reported in an annual submission. 
Effective January 1, 2022, these reporting obligations will extend to include transfers of value made to certain non-physician 
providers such as physician assistants and nurse practitioners; 
federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that 
potentially harm consumers;

• 

•  analogous state laws and regulations, including: state anti kickback and false claims laws, which may apply to our business 
practices, including, but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare 
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 U.S. federal government, or otherwise restrict payments that may be made to healthcare providers and 
other potential referral sources; state and local laws that require the licensure of sales representatives; 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 and pricing information; 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; and state 
laws related to insurance fraud in the case of claims involving private insurers; and

•  European and other foreign law equivalents of each of the laws, including reporting requirements detailing interactions with 
and payments to healthcare providers and data privacy and security laws and regulations that may be more stringent than 
those in the United States.

Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines 
and the relevant compliance guidance promulgated by the federal government in addition to requiring pharmaceutical manufac-
turers to report information related to payments to physicians and other health care providers or marketing expenditures. State 
and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each 
other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. 

We will be required to spend substantial time and money to ensure that our business arrangements with third parties comply with 
applicable healthcare laws and regulations. Recent healthcare reform legislation has strengthened these federal and state healthcare 
laws. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible 
that some of our business activities could be subject to challenge under one or more of such laws. 

Other laws that may affect our ability to operate include:

• 

• 

the anti-inducement law prohibits, among other things, the offering or giving of remuneration, which includes, without limita-
tion, any transfer of items or services for free or for less than fair market value (with limited exceptions), to a Medicare or 
Medicaid beneficiary that the person know or should know is likely to influence the beneficiary’s selection of a particular supplier 
of items or services reimbursable by a federal or state governmental program;
the U.S. Federal Food, Drug, and Cosmetic Act, or FDCA, which prohibits, among other things, the adulteration or misbranding 
of drugs, biologics and medical devices; and

•  European and other foreign law equivalents of each of the laws, including reporting requirements detailing interactions with 

and payments to healthcare providers. 

Violations of these laws can subject us to criminal, civil and administrative sanctions including monetary penalties, damages, fines, 
disgorgement, individual imprisonment and exclusion from participation in government funded healthcare programs, such as 
Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement 
or similar agreement to resolve allegations of non-compliance with these laws, reputational harm, and we may be required to curtail 
or restructure our operations. Moreover, we expect that there will continue to be federal and state laws and regulations, proposed 
and implemented, that could impact our future operations and business.

3.7.6.  HEALTHCARE REFORM

In the United States, the European Union and other foreign jurisdictions, there have been a number of legislative and regulatory 
changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue 
to be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs and improve the 
quality of healthcare. For example, in March 2010, the ACA became law. The ACA is a sweeping law intended to broaden access 
to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new 
transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry 
and impose additional health policy reforms. 

Among the provisions of the ACA of importance to our potential product candidates are the following:

•  an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic 
products, apportioned among these entities according to their market share in certain government healthcare programs, 
although this fee would not apply to sales of certain products approved exclusively for orphan indications; 

•  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 manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the minimum rebate for 
both branded and generic drugs and revising the definition of “average manufacturer price,” or AMP, for calculating and reporting 
Medicaid drug rebates on outpatient prescription drug prices and extending rebate liability to prescriptions for individuals 
enrolled in Medicare Advantage plans; 

•  a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for 

products that are inhaled, infused, instilled, implanted or injected; 

•  expanding the types of entities eligible for the 340B drug discount program; 
•  establishing the Medicare Part D coverage gap discount program, which requires manufacturers to provide a 50% (increased to 
70% effective January 1, 2019 pursuant to subsequent legislation) point-of-sale-discount off the negotiated price of applicable 
products to eligible beneficiaries during their coverage gap period as a condition for the manufacturers’ outpatient products 
to be covered under Medicare Part D; 

•  a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effec-

tiveness research, along with funding for such research; and

•  establishment of the Center for Medicare and Medicaid Innovation, or CMMI within CMS, to test innovative payment and service 

delivery models to lower Medicare and Medicaid spending, potentially including prescription product spending. 

Since its enactment, some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject 
to judicial, congressional, and executive challenges. As a result, there have been delays in the implementation of, and action taken 
to repeal or replace, certain aspects of the ACA. insurance markets may rise.

Since January 2017, President Trump has signed several executive orders and other directives designed to delay, circumvent, or 
loosen certain requirements mandated by the ACA. On January 20, 2017, President Trump signed an Executive Order directing 
federal agencies with authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the imple-
mentation of any provision of the ACA that would impose a fiscal burden on states or a cost, fee, tax, penalty or regulatory burden 
on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. Further, on October 
13, 2017, President Trump signed an executive order terminating the cost-sharing subsidies that reimburse insurers under the 
ACA. Several state Attorneys General filed suit to stop the administration from terminating the subsidies, but their request for a 
restraining order was denied by a federal judge in California on October 25, 2017. The loss of the cost share reduction payments is 
expected to increase premiums on certain policies issued by qualified health plans under the ACA. Further, on June 14, 2018, the 
U.S. Court of Appeals for the Federal Circuit ruled that the federal government was not required to pay more than $12 billion in 
ACA risk corridor payments to third-party payors who argued were owed to them. This was appealed to the U.S. Supreme Court, 

110  |  Regulatory Framework

which heard arguments on December 10, 2019. We cannot predict how the U.S. Supreme Court will rule. The effects of this gap 
in reimbursement on third-party payors, the viability of the ACA marketplace, providers, and potentially our business, are not yet 
known. In December 2018, CMS published a final rule permitting further collections and payments to and from certain ACA qualified 
health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of the federal district 
court litigation regarding the method CMS uses to determine this risk adjustment. In addition, CMS published a final rule that would 
give states greater flexibility, starting in 2020, in setting benchmarks for insurers in the individual and small group marketplaces, 
which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces. 
On December 10, 2019, the U.S. Supreme Court heard arguments in Moda Health Plan, Inc. v. United States, which will determine 
whether the government must make risk corridor payments. The Supreme Court’s decision will be released in the coming months.

While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the 
ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or Tax Act, includes a provision that decreased the tax-based 
shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all 
or part of a year, commonly referred to as the “individual mandate,” to $0, effective January 1, 2019. On December 14, 2018, 
a U.S. District Court judge in the Northern District of Texas ruled that the individual mandate portion of the ACA is an essential 
and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Cuts and Jobs Act, the 
remaining provisions of the ACA are invalid as well. The Trump administration and CMS have both stated that the ruling will have no 
immediate effect, and on December 30, 2018, the same judge issued an order staying the judgment pending appeal. On December 
18, 2019, the Fifth Circuit U.S. Court of Appeals held that the individual mandate is unconstitutional and remanded the case to the 
lower court to reconsider its earlier invalidation of the full ACA. It is unclear how this decision and any subsequent appeals and 
other efforts to repeal and replace the ACA will impact the ACA and our business. Litigation and legislation over the ACA are likely 
to continue, with unpredictable and uncertain results. We will continue to evaluate the effect that the ACA and its possible repeal 
and replacement has on our business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These new laws may result in 
additional reductions in Medicare and other healthcare funding. For example, on August 2, 2011, the Budget Control Act of 2011, 
among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked 
with recommending a targeted deficit reduction of at least $1.2 trillion for the years 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 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due 
to subsequent legislative amendments to the statute, including without limitation the Bipartisan Budget Act of 2015, will remain 
in effect through 2029 unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 
2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including 
hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to 
recover overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and 
other health care funding, which could have a material adverse effect on our customers and accordingly, our financial operations. 

Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives. The Trump 
administration’s budget proposal for fiscal years 2019 and 2020 contains further drug price control measures that could be enacted 
during the 2019 budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans 
to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and 
to eliminate cost sharing for generic drugs for low-income patients. Additionally, the Trump administration released a “Blueprint” 
to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer compe-
tition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of 
their products and reduce the out of pocket costs of drug products paid by consumers. While any proposed measures will require 
authorization through additional legislation to become effective, Congress and the Trump administration have each indicated that 
it will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures are 
increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, 
including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure 
and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. The 
Department of Health and Human Services (HHS) has already started the process of soliciting feedback on some of these measures 

Regulatory Framework    |  111 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXBUSINESSand, at the same time, is immediately implementing others under its existing authority. For example, in May 2019, CMS issued a 
final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020. This final 
rule codified CMS’s policy change that was effective January 1, 2019.

In May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy, a type of prior authori-
zation, for Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that was effective January 1, 2019.

In addition, recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for 
their marketed products. Specifically, there have been several recent U.S. Congressional inquiries and proposed bills 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. We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit 
the amounts that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand 
for our product candidates or additional pricing pressures. 

Further, legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promo-
tional activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether 
FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals, if 
any, of our product candidates, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may 
significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing 
conditions and other requirements. 

Individual states in the United States have also become increasingly aggressive in passing legislation and implementing regulations 
designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, 
restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to 
encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-
party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, 
regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical 
products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the 
ultimate demand for our products or put pressure on our product pricing, which could negatively affect our business, results of 
operations, financial condition and prospects. 

In the European Union, similar political, economic and regulatory developments may affect our ability to profitably commercialize our 
current or any future products. In addition to continuing pressure on prices and cost containment measures, legislative developments 
at the European Union or member state level may result in significant additional requirements or obstacles that may increase our 
operating costs. The delivery of healthcare in the European Union, including the establishment and operation of health services 
and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and 
policy. National governments and health service providers have different priorities and approaches to the delivery of health care 
and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most 
European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health 
service providers. Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop 
and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval 
activities and affect our ability to commercialize any products for which we obtain marketing approval. In international markets, 
reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings 
on specific products and therapies. 

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or adminis-
trative action, either in the United States or abroad. If we or our collaborators are slow or unable to adapt to changes in existing 
requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory 
compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or 
sustain profitability, which would adversely affect our business.

From time to time we may become involved in legal, governmental or arbitration proceedings or be subject to claims arising in

4.  Management’s Discussion and Analysis 
of Financial Condition and Results of 
Operations

4.1.  Operating and Financial Review

4.1.1.  OVERVIEW

Since our inception in 2008, we have focused most of our financial resources and efforts towards developing our SIMPLE AntibodyTM 
Platform and antibody engineering technologies, identifying potential product candidates, establishing process, development and 
manufacturing capabilities for our product candidates and advancing multiple discovery programs into the clinic. We have advanced 
six internally developed product candidates into clinical development—efgartigimod, cusatuzumab, ARGX111, ARGX109, ARGX-112 
and ARGX-115 (ABBV-151) — three into the preclinical stage—ARGX-116, ARGX-117 and ARGX-118 —and currently have multiple 
programs in the discovery stages. Through December 31, 2019, we have raised an aggregate gross proceeds of €1,396 million, 
including (i) an aggregate of €46.0 million from the private placement of equity securities in 2008, 2009 and 2011, (ii) €41.8 million 
from our initial public offering on the Euronext Brussels in 2014, (iii) €46.0 million from the private placement of equity securities, 
primarily to U.S. based institutional investors, in 2016, (iv) $114.7 million (approximately €102.1 million) from our initial U.S. public 
offering on the Nasdaq Global Select Market in May 2017, (v) $265.5 million (approximately €225.6 million) from our second U.S 
public offering on the Nasdaq Global Select Market in December 2017, (vi) $300.6 million (approximately €255.7 million) from our 
third U.S public offering on the Nasdaq Global Select Market in September 2018, (vi) €176.7 million from the private placement 
of equity securities as part of the closing of the global collaboration and license agreement with Janssen in January 2019 and (viii) 
€502.2 million from a global offering in November 2019. In addition, as of December 31, 2019, we have received upfront payments, 
milestone payments and research and development service fees from our collaborators totaling €420.2 million and have received 
€26.9 million in grants and incentives from governmental bodies. As of December 31, 2019, we had cash, cash equivalents and 
current financial assets of €1,335.8 million.

Our balance sheet shows our total assets accumulate to €1,433.3 million for the year ended December 31, 2019, compared to 
€587,6 million for the year ended December 31, 2018 and €370,9 million for the year ended December 31, 2017. The main reason 
for the material change in balance sheet total are the various equity financing rounds (described in paragraph 5.2.3 ‘History of 
Share Capital’), completed over the period covered by the financial statements incorporated herein by reference (see chapter 11 
“Information Incorporated by Reference”).

Since our inception, we have incurred significant operating losses. We do not currently have any approved products and have 
never generated any revenue from product sales. Our ability to generate revenue sufficient to achieve profitability will depend 
significantly upon the successful development and eventual commercialization of one or more of our product candidates, which 
may never occur. For the years ended December 31, 2019 and 2018, we incurred total comprehensive losses of €163.0 million and 
€66.6 million, respectively. As of December 31, 2019, we had accumulated losses of €332.6 million.

We expect our expenses to increase substantially in connection with our ongoing development activities related to our preclinical 
and clinical programs. In addition, we expect to continue to incur significant costs associated with operating as a public company 
in the United States. We anticipate that our expenses will increase substantially if and as we:

•  execute the Phase 3 clinical trials of efgartigimod in MG in ITP and in PV;
• 
• 
• 
• 

complete the Phase 2 clinical trials of efgartigimod in PV and launch a Phase 2 clinical trial in CIDP;
complete the Phase 2 clinical trials of cusatuzumab in AML and high risk MDS;
jointly develop and commercialize cusatuzumab with Janssen as per the collaboration agreement signed in December 2018;
seek regulatory approvals for any product candidates that successfully complete clinical trials;

116  |  Operating and Financial Review

•  potentially establish a sales, marketing and distribution infrastructure and scale up manufacturing capabilities to commercialize 

any product candidates for which we may obtain regulatory approval;

•  continue the research and development of our other clinical and preclinical stage product candidates and discovery stage 

programs;
seek to enhance our technology platform and discover and develop additional product candidates;

• 
•  maintain, expand and protect our intellectual property portfolio, including litigation costs associated with defending against 

alleged patent infringement claims;

•  add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support 

our product development and potential future commercialization efforts; and

•  experience any delays or encounter any issues any of the above, including failed studies, ambiguous trial results, safety issues 

or other regulatory challenges.

We expect that the costs of development and commercialization will also significantly increase due to the extended product devel-
opment roadmap for cusatuzumab as part of our collaboration with Janssen. Although this collaboration agreement provides for a 
joint decision process to approve the development plan as well as the budget, we will not control the actual amounts spent within 
such approved budget and we cannot control or guarantee that these funds are spent in the most efficient way.

Revenue
The Company generates revenue from collaborations and strategic alliances. The Company applies a five-step model to determine 
when, how and at what amount revenue is to be recognized depending on whether certain criteria are met.

1. 

Identify the contracts

In its current arrangements, the Company is licensing its Intellectual Property, providing research and development services and in 
the future, selling its products to collaborative entities. Revenue is generated through these arrangements via upfront payments, 
milestone payments based on development criteria, research and development service fees and future sales-based milestones 
and sales-based royalties.

2. 

Identify performance obligations

The Company has determined that there is one single performance obligation for certain arrangements in its material ongoing license 
and collaboration arrangements, that being the transfer of a license combined with performance of research and development 
services.

This is because we consider that the license has no stand-alone value without the Company being further involved in the research 
and development collaboration and that there is interdependence between the license and the research and development services 
to be provided. We estimate that the Company’s activities during the collaboration are going to significantly add to Intellectual 
Property and thereby the value of the programs.

3. 

Determine the transaction price

We have analyzed the transaction prices of our material ongoing license and collaboration arrangements currently composed of 
upfront payments, milestone payments and research and development service fees being delivered. Any variable consideration, 
such as development milestone payments that are promised in exchange for development services or the license of IP, is only 
included in the transaction price as from the moment the achievement of the related milestone event is highly probable (usually 
at the time of achievement of the milestone event). At the end of each subsequent reporting period, the Company re-evaluates 
the probability of achievement of such milestones and any related constraint, and, if necessary, adjusts the estimate of the overall 
transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in 
the period of adjustment. The Company’s collaborators may be required to pay the Company sales-based milestone payments or 
royalties on future sales of commercial products. The Company recognizes revenues related to sales-based milestone and royalty 
payments upon the later to occur of (i) achievement of the collaborator’s underlying sales or (ii) satisfaction of any performance 
obligation(s) related to these sales, in each case assuming the license to the Company’s intellectual property is deemed to be the 
predominant item to which the sales-based milestones and/or royalties relate.

118  |  Operating and Financial Review

4. 

Allocate the transaction price

In principle, an entity shall allocate the transaction price to each performance obligation identified in the contract on a relative 
stand-alone selling price. However, the transaction price of certain of our arrangements is allocated to a single performance obli-
gation since the transfer of a license is considered to be combined with the performance of research and development services.

Therefore, research and development milestone payments are variable considerations that are entirely allocated to the single 
performance obligation.

5. 

Recognize revenue

Revenue from certain arrangements is recognized over time as the Company satisfies a single performance obligation. Our collab-
orative partner entities simultaneously receive the benefits provided by the Company’s performance as the Company performs.

The Company recognizes upfront payments and milestone payments, allocated to a single performance obligation over the estimated 
service period based on a pattern that reflects the transfer of the services. The revenues recognized reflect the level of service 
during each period. In this case, the Company would use an input model that considers estimates of the percentage of total research 
and development service costs that are completed each period compared to the total estimated services costs (percentage of 
completion method).

Research and development service fees are recognized as revenue when costs are incurred and agreed by the parties as the Company 
is acting as a principal in the scope of its stake of the research and development activities of its ongoing license and collaboration 
agreements.

Other Operating Income
As a company that carries extensive research and development activities, we benefit from various grants, research and development 
incentives and payroll tax rebates from certain governmental agencies. These grants and research and development incentives 
generally aim to partly reimburse approved expenditures incurred in our research and development efforts. The primary grants, 
research and development incentives and payroll tax rebates are as follows:

Government Grants
We have received several grants from agencies of the Flemish government to support various research programs focused on 
technological innovation in Flanders. These grants require us to maintain a presence in the Flemish region for a number of years 
and invest according to pre agreed budgets.

Research and Development Incentives
Companies in Belgium can benefit from tax savings on amounts spent on research and development by applying a one time or 
periodic tax deduction on research and development expenditures for the acquisition or development of patents. This tax credit is 
a reduction of the corporate income taxes for Belgian statutory purposes and is transferrable to the next four accounting periods. 
These tax credits are paid to us in cash after five years to the extent they have not been offset against corporate taxes due.

Payroll Tax Rebates
We also benefit from certain rebates on payroll withholding taxes for scientific personnel. The government grants and research and 
development incentives generally aim to partly reimburse approved expenditures incurred in our research and development efforts 
and are credited to the income statement, under other operating income, when the relevant expenditure has been incurred and 
there is reasonable assurance that the grant or research and development incentive is receivable.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXMANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSResearch and Development Expenses
Research and development expenses consist principally of:

•  personnel expense related to compensation of research and development staff and related expenses, including salaries, benefits 

and share based compensation expenses;

•  external research and development expenses related to (i) chemistry, manufacturing and control costs for our product candi-
dates, both for preclinical and clinical testing, all of which is conducted by specialized contract manufacturers, (ii) fees and 
other costs paid to contract research organizations in connection with preclinical testing and the performance of clinical 
trials for our product candidates and (iii) costs associated with regulatory submissions and approvals, quality assurance and 
pharmacovigilance;

•  materials and consumables expenses;
•  depreciation and amortization of tangible and intangible fixed assets used to develop our product candidates; and
•  other expenses consisting of (i) costs associated with obtaining and maintaining patents and other intellectual property and (ii) 

other costs such as travel expenses related to research and development activities.

The following table shows our research and development expenses for the past three fiscal years:

Research and development expenses (thousand euros)

2017

51,740

2018

83,609

2019

197,665

We incur various external expenses under our collaboration agreements for material and services consumed in the discovery and 
development of our partnered product candidates. Under our agreements with Shire, LEO Pharma and Staten, our collaboration 
partner reimbursed us for part or all of these external expenses and compensates us for time spent on the project by our employees. 
Under our agreement with AbbVie, our own research and development expenses are not reimbursed. Research and development 
expenses are recognized in the period in which they are incurred. Under our agreement with Janssen, we assume certain develop-
ment obligations, and are jointly responsible with Janssen for all research, development and regulatory costs relating to the product.

Our research and development expenses may vary substantially from period to period based on the timing of our research and 
development activities, including the timing of the initiation of clinical trials, production of product batches and enrolment of 
patients in clinical trials. Research and development expenses are expected to increase as we advance the clinical development 
of efgartigimod and cusatuzumab and further advance the research and development of our other preclinical and discovery stage 
programs. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate 
the nature, timing and estimated costs of the efforts that will be necessary to complete the development of, or the period, if any, in 
which material net cash inflows may commence from, any of our product candidates. This is due to numerous risks and uncertainties 
associated with developing drugs, as fully described in chapter 1 “Risk Factors” and including the uncertainty of:

• 
• 
• 

the scope, rate of progress and expense of our research and development activities;
the successful enrollment in, and completion of clinical trials;
the ability to market, commercialize and achieve market acceptance for efgartigimod, cusatuzumab or any other product 
candidate that we may develop in the future, if approved; 

•  establishing and maintaining a continued acceptable safety profile for our product candidates;
• 
• 

the terms, timing and receipt of regulatory approvals from applicable regulatory authorities; 
the successful completion of preclinical studies necessary to support IND applications in the United States or similar applications 
in other countries;
the expense of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights; and

• 
•  our current and future collaborators continuing their collaborations with us.

Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of (i) personnel expenses relating to salaries and related costs for 
personnel, including share based compensation, of our employees in executive, finance, business development, commercial and 
support functions, (ii) consulting fees relating to professional fees for accounting, business development, IT, audit, commercial, legal 

120  |  Operating and Financial Review

services and investor relations costs, (iii) board expenses consisting of directors’ fees, travel expenses and share based compensation 
for non executive board members, (iv) allocated facilities costs and (v) other selling, general and administrative expenses, including 
leasing costs, office expenses, travel costs.

We expect our general and administrative expenses to increase as we continue to support our growth and operate as a public 
company in the United States. Such costs include increases in our finance and legal personnel, additional external legal and audit 
fees, and expenses and costs associated with compliance with the regulations governing public companies. We expect our selling 
expenses to increase significantly with preparatory marketing and market access activities with respect to the potential future 
commercialization of one or more of our product candidates, if approved.

Financial Income (Expense)
Financial income reflects interest earned on the financial investments of our cash and cash equivalents and financial assets. Financial 
expense corresponds to interest expenses.

Exchange Gains (Losses)
Our exchange gains (losses) relate to (i) our transactions denominated in foreign currencies, mainly in U.S. dollars, Swiss francs, 
British pounds and Japanese yens which generate exchange gains or losses and (ii) the translation at the reporting date of assets and 
liabilities denominated in foreign currencies into euros, which is our functional and presentation currency. For more information on 
currency exchange fluctuations on our business, please see paragraph 1.7.4 on page 37. We have no derivative financial instruments 
to hedge interest rate and foreign currency risk.

Income Tax
We have a history of losses. We expect to continue incurring losses as we continue to invest in our clinical and pre clinical develop-
ment programs and our discovery platform, and as we prepare for the potential future commercial launch of one or more of our 
product candidates, if approved. Consequently, we do not have any deferred tax asset on our consolidated statement of financial 
position.

We are incurring income tax expense on the profit generated in argenx US, Inc and argenx Japan K.K. in view of the transfer price 
agreements set up between argenx BV and argenx US, Inc. and between argenx BV and argenx Japan K.K.

Critical Accounting Policies and Significant Judgements and Estimates
In the application of our accounting policies, we are required to make judgments, 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. The following elements are areas where key assumptions concerning the 
future, and other key sources of estimation uncertainty at the end of the reporting period, have a significant risk of causing a material 
adjustment to the carrying amounts of assets and liabilities within the next financial year.

Critical judgements in applying accounting policies

Revenue recognition
Revenue from certain arrangements is recognized as the company satisfies a single performance obligation. The company recognizes 
upfront payments and milestone payments, allocated to a single performance obligation over the estimated service period based 
on a pattern that reflects the transfer of the services. The revenue recognized would reflect the level of service during each period. 
In this case, the company would use an input model that considers estimates of the percentage of total research and development 
service costs that are completed each period compared to the total estimated service costs (percentage of completion method). 
Research and development service fees are recognized as revenue when costs are incurred and agreed by the parties, as the 
company is acting as a principal in the scope of its stake in the research and development activities of its ongoing license and 
collaboration agreements.

Research and development costs are charged to expense as incurred and are typically made up of payroll costs, clinical and preclinical 
activities, drug development and manufacturing costs, including costs for clinical research organizations and investigative sites. Costs 
for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of 
specific tasks using data such as information provided by vendors on their actual costs incurred. Payments for these activities are 
based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the 
financial statements as prepaid expenses.

Our revenue increased by €48.3 million for the year ended December 31, 2019 to €69.8 million, compared to €21.5 million for the 
year ended December 31, 2018 and €36.4 million for the year ended December 31, 2017.

The increase of €13.7 million in upfront payments recognized for the year ended December 31, 2019 compared to the year ended 
December 31, 2018 was primarily related to the partial recognition of the upfront payment received under the collaboration and 
license agreement for cusatuzumab with Janssen. Upfront payments recognized for the year ended December 31, 2018 and 2017 
correspond principally to the recognition of payments received in connection with entering into the collaboration agreements with 
LEO Pharma in May 2015 and with AbbVie in April 2016.

The increase of €16.6 million in milestone payments recognized for the year ended December 31, 2019 compared to the year ended 
December 31, 2018 was primarily due to related to the recognition of the milestone payment following the initiation of a first-in-
human clinical trial with ABBV-151 (formerly named ARGX-115) under the AbbVie collaboration. Milestone payments recognized 
for the year ended December 31, 2018 and 2017 correspond principally to the recognition of milestone payments received under 
the AbbVie and LEO Pharma collaboration agreements.

As of January 1, 2018, upon the adoption of IFRS 15, both the upfront payments and milestone payments are recognized as revenue 
over the estimated period of the Company’s continuing involvement in the research and development activities provided for under 
the terms of these agreements.

The increase of €17.9 million in research and development service fees for the year ended December 31, 2019 compared to the year 
ended December 31, 2018 is primarily related to the recognition of research and development service fees under the collaboration 
and license agreement for cusatuzumab with Janssen. Research and development services recognized for the year ended December 
31, 2018 and 2017 are primarily linked to payments received under the collaboration agreements with LEO Pharma and Shire.

Other operating income increased by €5.1 million for the year ended December 31, 2019 to €12.8 million, compared to €7.7 million 
and €4.5 million for the years ended December 31, 2018 and 2017 respectively. In April and September 2018, we received two 
new grants from the Flanders Innovation and Entrepreneurship Agency (VLAIO), which resulted in an increase in government grant 
income in the years 2018 and 2019. For the year ended December 31, 2019, we accrued research and development incentives 
income of €4.8 million compared to €2.2 million and €1.0 million for the years ended December 31, 2018 and 2017 respectively. 
The income corresponds to Belgian research and development incentives with regard to incurred research and development 
expenses which will be paid to us in cash after a five-year period, if not offset against the taxable basis over the respective period. 
The increase in research and development incentives income is due to (i) an extension of the scope in 2018 which allows us to 
take more research and development expenses in consideration for the calculation and (ii) an overall increase in the research and 
development expenses. We accounted for €5.7 million of payroll tax rebates in the year ended December 31, 2019 compared to 
€3.8 million and €3.4 million for the years ended December 31, 2018 and 2017 respectively, for employing certain research and 
development personnel. The increase in payroll tax rebates results directly from an increase in the number of employees employed 
in our research and development functions.

3.7.5 “Healthcare laws and Regulation”.

personnel expenses. The increase of €19.2 million in personnel expense for the year ended December 31, 2019 in comparison to the 
year ended December 31,2018 corresponded principally to (i) an increase of €8.5 million for share-based compensation expenses 
related to the grant of stock options to our research and development employees and (ii) increased costs associated with additional 
research and development personnel. We employed 118 employees in our research and development functions on December 31, 
2019 compared to 75 employees on December 31, 2018 and 58 employees on December 31, 2017.

Our external research and development expenses for the year ended December 31, 2019 totaled €137.1 million, compared to 
€48.6 million and €27.9 million for the years ended December 31, 2018 and 2017 respectively. The increase reflects higher clinical 
trial costs and manufacturing expenses related to the development of our product candidate portfolio. The table below provides 
additional detail on our external research and development expenses by program:

External research and development expenses for our lead product candidate efgartigimod totalled €84.2 million for the year ended 
December 31, 2019, compared to €30.9 million and €12.4 million for the years ended December 31, 2018 and 2017 respectively. 
The increase corresponds primarily to increased manufacturing and clinical development activities in relation to the execution of 
two Phase 3 clinical trials in MG and the preparation for and initiation of two Phase 2 clinical trials in CIDP and two Phase 3 clinical 
trials in ITP.

External research and development expenses for cusatuzumab totalled €38.7 million for the year ended December 31, 2019, 
compared to €9.3 million and €3.1 million for the years ended December 31, 2018 and 2017 respectively. The increase resulted 
primarily from the initiation of a Phase 2 trial in up to 150 newly diagnosed “unfit” AML patients who are not eligible for intensive 
chemotherapy, as part of the collaboration and license agreement with Janssen.

External research and development expenses on other programs totalled €14.2 million for the year ended December 31, 2019, 
compared to €8.6 million and €12.4 million for the years ended December 31, 2018 and 2017 respectively. The increase is primarily 
due to increased research and development expenses in relation to the advancement of our program with ARGX-117, a comple-
ment-targeting antibody against C2.

Our selling, general and administrative expenses totalled €64.6 million, €27.5 million and €12.4 million for the years ended December 
31, 2019, 2018 and 2017 respectively. The increase in our selling, general and administrative expenses for the year ended December 
31, 2019 was principally due to an increase of personnel expense, resulting from (i) increased costs of the share-based payment 
compensation plans related to the grant of stock options to our selling, general and administrative employees and (ii) increased 
costs associated with additional employees recruited to strengthen our selling, general and administrative activities, notably in 
preparation of the potential commercial launch of efgartigimod in the U.S. 

On December 31, 2019, we employed 70 employees in our selling, general and administrative functions, compared to 30 employees 
on December 31, 2018 and 15 employees on December 31, 2017.

Financial Income (Expense)
For the year ended December 31, 2019, financial income amounted to €14.4 million compared to €3.7 million for the year ended 
December 31, 2018 and €1.3 million for the year ended December 31, 2017. The increase of €10.7 million in 2019 related primarily 
to an increase in the interest received on our cash, cash equivalents and current financial assets.

Exchange Gains (Losses)
Exchange gains totaled €6.1 million for the year ended December 31, 2019 and were mainly attributable to unrealized exchange 
rate gains on our cash, cash equivalents and current financial assets position in U.S. dollars due to the favorable fluctuation of the 
EUR/USD exchange rate.

4.1.3.  LIQUIDITY AND CAPITAL RESOURCES

Sources of Funds
Since our inception in 2008, we have invested most of our resources to developing our product candidates, building our intellectual 
property portfolio, developing our supply chain, conducting business planning, raising capital and providing general and adminis-
trative support for these operations. We do not currently have any approved products and have never generated any revenue from 
product sales. To date, we have funded our operations through public and private placements of equity securities, upfront, milestone 
and expense reimbursement payments received from our collaborators, funding from governmental bodies and interest income 
from the investment of our cash, cash equivalents and financial assets. Through December 31, 2019, we have raised gross proceeds 
of €1,396 million from private and public offerings of equity securities, received €420.2 million in revenue from our collaborators, 
and €26.9 million in grants and incentives from governmental bodies.

Our cash flows may fluctuate and are difficult to forecast and will depend on many factors. On December 31, 2019, we had cash, 
cash equivalents and current financial assets (including money market funds) of € 1,335.8 million, compared to €564.6 million on 
December 31, 2018 and €359.8 million on December 31, 2017.

We have no ongoing material financing commitments, such as lines of credit or guarantees, that are expected to affect our liquidity 
over the next five years, other than leases and our (significant) commitments to Lonza which are detailed in note 30 of our consol-
idated financial statements for the period ending December 31, 2019.

Net Cash Used in Operating Activities
Net cash outflow from our operating activities decreased by €188.4 million to a net inflow of €134.6 million for the year ended 
December 31, 2019, compared to a net outflow of €53.8 million for the year ended December 31, 2018 and a net outflow of €36.5 
million for the year ended December 31, 2017. The net cash inflow from operating activities for the year ended December 31, 
2019 resulted primarily from the closing of the exclusive global collaboration and license agreement for cusatuzumab with Janssen 
which triggered a $300 million upfront payment, partially reduced by research and development expenses incurred in relation to 
the manufacturing and clinical development activities of efgartigimod, cusatuzumab and the advancement of other preclinical and 
discovery-stage product candidates.

Net Cash Used in Investing Activities
Investing activities consist primarily of the acquisition of current financial assets, purchase of intangible assets and interest received 
from the placements of our cash and cash equivalents and current financial assets. Cash flow used in investing activities represented 
a net outflow of €744.3 million for the year ended December 31, 2019, compared to a net outflow of €107.5 million for the year 
ended December 31, 2018 and a net outflow of €162.1 million for the year ended December 31, 2017. The net outflow for the year 
ended December 31, 2019 related primarily to (i) the investment of €708.1 million in current financial assets, including money 
market funds and U.S. term deposit accounts (compared to €114.6 million and €162.1 million for the years ended December 31, 
2018 and 2017 respectively), (ii) the investment of €39.9 million regarding the in-licensing of intellectual property rights in relation 
to the ENHANZE® drug delivery technology from Halozyme and (iii) €5.5 million interest received from the placement of our cash, 
cash equivalents and current financial assets ((compared to €3.7 million and €0.4 million for the years ended December 31, 2018 
and 2017 respectively).

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXMANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSNet Cash Provided by Financing Activities
Financing activities consist of net proceeds from our private placements and public offerings of our securities and exercise of stock 
options. The net cash inflow from financing activities was €659.4 million for the year ended December 31, 2019, compared to a 
net cash inflow of €244.7 million for the year ended December 31, 2018 and a net cash inflow of €305.4 million for the year ended 
December 31, 2017. The net cash inflow for the year ended December 31, 2019 was attributed to (i) €479.2 million net cash proceeds 
from our global offering in November 2019, (compared to €241.1 million net cash proceeds from our U.S. follow-on public offering 
of ADSs in September 2018, and €304.7 million from our initial and follow-on public offering in May and December 2017), (ii) €176.7 
million from a private placement following the closing of the exclusive global collaboration and license agreement for cusatuzumab 
with Janssen in January 2019 and (iii) €4.8 million proceeds received from the exercise of stock options in 2019 (compared to €2.3 
million for the year ended December 2018 and €0.7 million for the year ended December 31, 2017).

Operating and Capital Expenditure Requirements
We have never achieved profitability and, as of December 31, 2019, we had accumulated losses of €332.6 million. We expect to 
continue to incur significant operating losses for the foreseeable future as we continue our research and development efforts and 
seek to obtain regulatory approval and commercialization of our product candidates.

On the basis of current assumptions, we expect that our existing cash and cash equivalents and current financial assets will enable 
us to fund our operating expenses and capital expenditure requirements through at least the next 12 months. Because of the 
numerous risks and uncertainties associated with the development of efgartigimod, cusatuzumab and our other product candidates 
and discovery stage programs and because the extent to which we may enter into collaborations with third parties for the develop-
ment of these product candidates is unknown, we are unable to estimate the amounts of increased capital outlays and operating 
expenses associated with completing the research and development of our product candidates. Our future capital requirements for 
efgartigimod, cusatuzumab and our other product candidates and discovery stage programs will depend on many factors, including:

• 
• 
• 

• 

• 

• 

• 
• 

the progress, timing and completion of preclinical testing and clinical trials for our current or any future product candidates;
the number of potential new product candidates we identify and decide to develop;
the time and costs involved in obtaining regulatory approval for our product candidates and any delays we may encounter as a 
result of evolving regulatory requirements or adverse results with respect to any of our product candidates;
selling and marketing activities undertaken in connection with the potential commercialization of our current or any future 
product candidates, if approved, and costs involved in the creation of an effective sales and marketing organization;
the costs involved in growing our organization to the size needed to allow for the research, development and potential commer-
cialization of our current or any future product candidates;
the costs involved in filing patent applications and maintaining and enforcing patents or defending against claims or infringe-
ments raised by third parties;
the maintenance of our existing collaboration agreements and entry into new collaboration agreements;
the amount of revenues, if any, we may derive either directly or in the form of royalty payments from future sales of our product 
candidates, if approved; and

•  developments related to COVID-19 and its impact on the costs and timing associated with the conduct of our clinical trials, 

preclinical programs and other related activities.

5.2.  General Description of the Share Capital

5.2.1.  AUTHORIZ ED SHARE CAPITAL

Under Dutch Law (Section 2:67 of the DCC), a company’s authorized share capital sets out the maximum amount and number of 
shares that it may issue without amending its articles of association. Our Articles of Association provide for an authorized share 
capital in the amount of €9 million divided into 90 million shares, each with a nominal value of €0.10. All issued and outstanding 
shares have been fully paid up and the shares are held in dematerialized form. As of March 16, 2020, our issued and paid up share 
capital amounted to €4,279,107.60, represented by 42,791,076 ordinary shares with a nominal value of €0.10, each representing 
an identical fraction of our share capital. As of March 16, 2020, neither we nor any of our subsidiaries held any of our own shares.

5.2.2.  STOCK OPTI ONS

In addition to the shares already outstanding, we have granted options which upon exercise will lead to an increase in the number 
of our outstanding shares. A total of 4,358,769 options (where each option entitles the holder to subscribe for one new ordinary 
share) were outstanding and granted as of December 31, 2019. Upon exercise of these 4,358,769 options, a total amount of €277.8 
million in option exercise price would become payable to the Company by the optionees, increasing the Company’s share capital 
by the same amount. A total of 4,250,535 options (where each option entitles the holder to subscribe for one new ordinary share) 
were outstanding and granted as of March 16, 2020. Upon exercise of these 4,250,535 options, a total amount of €267.2 million 
in option exercise price would become payable to the Company by the optionees, increasing the Company’s share capital by the 
same amount. Apart from the options granted under the argenx Employee Stock Option Plan, we do not currently have other stock

On May 19, 2017, the underwriters of the offering exercised their over-allotment option to purchase 879,750 additional ADSs in 
full. As a result, argenx received €102.1 million of total gross proceeds from the offering, decreased by €9.6 million of underwriter 
discounts and commissions, and offering expenses, of which €8.9 million has been deducted from equity. The total net cash proceeds 
from this offering amounted to €92.5 million. 

On December 14, 2017, argenx offered 4,440,000 of its ordinary shares through a public offering in the United States in the form of

and commissions, and offering expenses, of which €14.1 million has been deducted from equity. The total net cash proceeds from 
the Offering amounted to €211.3 million. 

For both offerings completed in 2017, the ADSs are evidenced by American Depositary Receipts (ADRs), and each ADS represents 
the right to receive one ordinary share. These ADSs are listed on the Nasdaq Global Select Market under the symbol “ARGX”.

203,412 new shares were also issued in 2017 as a result of the exercise of stock options under the argenx Employee Stock Option Plan.

result, argenx received €255.7 million of gross proceeds from this offering, decreased by €14.8 million of underwriter discounts 
and commissions, and offering expenses, of which €14.6 million has been deducted from equity. The total net cash proceeds from

section 3.6 “Material Contracts/Collaboration Agreements”. The shareholding of Johnson & Johnson Innovation at the time of the 
issuance represented approximately 4.66% of argenx’s outstanding shares.

As a result of the exercise of options under the argenx Employee Stock Option Plan, 419,317 new shares were created in 2019.

On November 7, 2019, argenx offered 4,000,000 of its ordinary shares through a global offering which consisted of (i) a public 
offering of 2,010,057 ADSs in the U.S. and certain other countries outside the European Economic Area (EEA) at a price of $121.00

of underwriter discounts and commissions, and offering expenses, of which €23.0 million has been deducted from equity. The total 
net cash proceeds from the offering amounted to €479.0 million.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXGENERAL DESCRIPTION OF THE COMPANY AND ITS SHARE CAPITAL5.2.4.  AMERICAN DEPOS ITORY SHARE S

In connection with our IPO on Nasdaq, the Bank of New York Mellon, as depositary, registered and delivered American Depositary 
Shares, also referred to as ADSs. Each ADS represents one share (or a right to receive one share) deposited with ING Bank N.V., as 
custodian for the depositary in the Netherlands. Each ADS also represents any other securities, cash or other property which may be 
held by the depositary. The depositary’s office at which the ADSs are administered is located at 101 Barclay Street, New York, New 
York 10286. The Bank of New York Mellon’s principal executive office is located at 225 Liberty Street, New York, New York 10286. 

An ADS holder will not be treated as one of our shareholders and does not have shareholder rights. Dutch law governs shareholder 
rights. The depositary will be the holder of the shares underlying the ADSs. A registered holder of ADSs has ADS holder rights. A 
deposit agreement among us, the depositary, ADS holders and all other persons indirectly or beneficially holding ADSs sets out ADS 
holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs. 

The depositary has agreed to pay or distribute to ADS holders the cash dividends or other distributions it or the custodian receives 
on shares or other deposited securities, upon payment or deduction of its fees and expenses. ADS holders will receive these 
distributions in proportion to the number of shares their ADSs represent. An ADS holder may surrender his ADSs at the depositary’s 
office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the 
depositary will deliver the shares and any other deposited securities underlying the ADSs to the ADS holder or a person the ADS 
holder designates at the office of the custodian. Or, at an ADS holder’s request, risk and expense, the depositary will deliver the 
deposited securities at its office, if feasible. 

The depositary may charge the ADS holder a fee and its expenses for instructing the custodian regarding delivery of deposited 
securities. ADS holders may instruct the depositary how to vote the number of deposited shares their ADSs represent. If we request 
the depositary to solicit the ADS holders’ voting instructions (and we are not required to do so), the depositary will notify them of 
a General Meeting and send or make voting materials available to them. Those materials will describe the matters to be voted on 
and explain how ADS holders may instruct the depositary how to vote. For instructions to be valid, they must reach the depositary 
by a date set by the depositary. The depositary will try, as far as practical, subject to Dutch law and the provisions of our Articles 
of Association or similar documents, to vote or to have its agents vote the shares or other deposited securities as instructed by 
ADS holders. If we do not request the depositary to solicit the ADS holders’ voting instructions, an ADS holder can still send voting 
instructions, and, in that case, the depositary may try to vote as he instructs, but it is not required to do so. In any event, the 
depositary will not exercise any discretion in voting deposited securities and it will only vote or attempt to vote as instructed or 
as described in the following sentence. If we asked the depositary to solicit an ADS holder’s instructions at least 45 days before 
the meeting date but the depositary does not receive voting instructions from an ADS holder by the specified date, it will consider 
such ADS holder to have authorized and directed it to give a discretionary proxy to a person designated by us to vote the number 
of deposited securities represented by its ADSs. The depositary will give a discretionary proxy in those circumstances to vote on all 
questions to be voted upon unless we notify the depositary that: 

•  we do not wish to receive a discretionary proxy;
• 
• 

there is substantial shareholder opposition to the particular question; or
the particular question would have an adverse impact on our shareholders. 

We are required to notify the depositary if one of the conditions specified above exists. In order to give an ADS holder a reasonable 
opportunity to instruct the depositary as to the exercise of voting rights relating to our shares, if we request the depositary to 
act, we agree to give the depositary notice of any meeting and details concerning the matters to be voted upon at least 30 days in 
advance of the meeting date.

5.2.5.  MODIFICATION OF SHARE CAPI TAL OR R I GHT S AT TACH ED TO T H E SH AR E S

Issue of Shares
The Articles of Association provide that shares may be issued or rights to subscribe for our shares may be granted pursuant to a 
resolution of the shareholders at the General Meeting, or alternatively, by our board of directors if so designated by the shareholders 
at the General Meeting. A resolution of the shareholders at the General Meeting to issue shares, to grant rights to subscribe for 
shares or to designate our board of directors as the corporate body of the company authorized to do so can only take place at the 
proposal of our board of directors with the consent of the majority of the non-executive directors. Shares may be issued or rights 
to subscribe for shares may be granted by resolution of our board of directors, if and insofar as our board of directors is designated 
to do so by the shareholders at the General Meeting. Designation by resolution of the shareholders at the General Meeting cannot 
be withdrawn unless determined otherwise at the time of designation. The scope and duration of our board of directors’ authority 
to issue shares or grant rights to subscribe for shares (such as granting stock options or issuing convertible bonds) is determined by 
a resolution of the shareholders at the General Meeting and relates, at the most, to all unissued shares in the Company’s autho-
rized capital at the relevant time. The duration of this authority may not exceed a period of five years. Designation of our board 
of directors as the body authorized to issue shares or grant rights to subscribe for shares may be extended by a resolution of the 
shareholders at the General Meeting for a period not exceeding five years in each case. The number of shares that may be issued 
is determined at the time of designation. 

No shareholders’ resolution or board of directors’ resolution is required to issue shares pursuant to the exercise of a previously 
granted right to subscribe for shares. A resolution of our board of directors to issue shares and to grant rights to subscribe for shares 
can only be taken with the consent of the majority of the non-executive directors. 

On May 7, 2019, the shareholders at the General Meeting designated our board of directors as the corporate body competent to 
issue shares under the Option Plan and to limit or exclude pre-emptive rights of shareholders for such shares and option rights to 
subscribe for shares with the prior consent of the majority of the non-executive directors for a period of 18 months. On May 7, 2019, 
the shareholders at the General Meeting designated our board of directors as the corporate body competent to issue additional 
shares and grant rights to subscribe for shares and to limit or exclude pre-emptive rights of shareholders for such shares with the 
prior consent of the majority of the non-executive directors for a period of 18 months. In its resolution, the shareholders at the 
General Meeting restricted the competency of our board of directors under this second authorization as regards the issue of shares 
and the grant of rights to subscribe for shares to a maximum of 20% of our total issued and outstanding share capital as at the day 
of that meeting. The purpose of this authorization is to allow the board of directors the general flexibility to issue additional shares 
as and when the need may arise or an opportunity would present itself, including to issue shares and grant rights to subscribe for 
shares and to limit or exclude pre-emptive rights of shareholders for such shares for the purpose of the admission to listing and 
trading of securities in our capital on Nasdaq and/or Euronext. While there is no current intention to benefit any specific person 
with this authorization to restrict the pre-emptive rights of the existing shareholders, when using this authorization the board will 
be able to restrict the pre-emptive rights in whole or in part, including for the benefit of specific persons. The board’s ability to 
restrict the pre-emptive rights in whole or in part could be used by the board as a potential anti-takeover measure, although there 
is currently no likely scenario in which we expect that such ability would be used as an anti-takeover measure.

Pre-emptive rights
Dutch law (Section 2:96aa of the DCC) and the Articles of Association give shareholders pre-emptive rights to subscribe on a pro 
rata basis for any issue of new shares or, upon a grant of rights, to subscribe for shares. Holders of shares have no pre-emptive 
rights upon (1) the issue of shares against a payment in kind (being a contribution other than in cash); (2) the issue of shares to 
our employees or the employees of a member of our group; and (3) the issue of shares to persons exercising a previously granted 
right to subscribe for shares.

A shareholder may exercise pre-emptive rights during a period of at least two weeks from the date of the announcement of the issue 
of shares. Pursuant to the Articles of Association, the shareholders at the General Meeting may restrict or exclude the pre-emptive 
rights of shareholders. A resolution of the shareholders at the General Meeting to restrict or exclude the pre-emptive rights or to 
designate our board of directors as our body authorized to do so, may only be adopted on the proposal of our board of directors 
with the consent of the majority of the non-executive directors. A resolution of the shareholders at the General Meeting to exclude 

General Description of the Share Capital    |  137 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXGENERAL DESCRIPTION OF THE COMPANY AND ITS SHARE CAPITALor restrict pre-emptive rights, or to authorize our board of directors to exclude or restrict pre-emptive rights, requires a majority 
of at least two-thirds of the votes cast, if less than 50% of our issued and outstanding share capital is present or represented at 
the General Meeting. 

With respect to an issuance of shares pursuant to a resolution of our board of directors, the pre-emptive rights of shareholders may 
be restricted or excluded by resolution of our board of directors if and insofar as our board of directors is designated to do so by 
the shareholders at the General Meeting. A resolution of our board of directors to restrict or exclude pre-emptive rights can only 
be taken with the consent of the majority of the non-executive directors. 

The designation of our board of directors as the body competent to restrict or exclude the pre-emptive rights may be extended by a 
resolution of the shareholders at the General Meeting for a period not exceeding five years in each case. Designation by resolution 
of the shareholders at the General Meeting cannot be withdrawn unless determined otherwise at the time of designation. 

On May 7, 2019, the shareholders at the General Meeting designated our board of directors as the corporate body competent to 
issue shares under the Option Plan up to a maximum of 20% of the outstanding capital and to limit or exclude pre-emptive rights of 
shareholders for such shares and option rights to subscribe for shares with the prior consent of the majority of the non-executive 
directors for a period of 18 months.

Acquisition of Shares by the Company
We may not subscribe for our own shares on issue. We may acquire fully paid-up shares at any time for no consideration or, if:

•  our shareholders’ equity less the payment required to make the acquisition, does not fall below the sum of called-up and paid-in 

share capital and any statutory reserves;

•  we and our subsidiaries would thereafter not hold shares or hold a pledge over shares with an aggregate nominal value 

exceeding 50% of our issued share capital; and

•  our board of directors has been authorized thereto by the shareholders at the General Meeting. 

As part of the authorization, the shareholders at the General Meeting must specify the number of shares that may be repurchased, 
the manner in which the shares may be acquired and the price range within which the shares may be acquired. An authorization 
by the shareholders at the General Meeting to our board of directors for the repurchase of shares can be granted for a maximum 
period of 18 months. No authorization of the shareholders at the General Meeting is required if ordinary shares are acquired by 
us with the intention of transferring such ordinary shares to our employees under the Option Plan. A resolution of our board of 
directors to repurchase shares can only be taken with the consent of the majority of the non-executive directors. 

138  |  General Description of the Share Capital

Shares held by us in our own share capital do not carry a right to any distribution. Furthermore, no voting rights may be exercised 
for any of the shares held by us or our subsidiaries unless such shares a are subject to the right of usufruct or to a pledge in favor 
of a person other than us or its subsidiaries and the voting rights were vested in the pledgee or usufructuary before us or its 
subsidiaries acquired such shares. Neither we nor our subsidiaries may exercise voting rights in respect of shares for which we or 
our subsidiaries have a right of usufruct or a pledge. 

Reduction of Share Capital
The shareholders at the General Meeting may, upon a proposal of our board of directors with the consent of the majority of the 
non-executive directors, resolve to reduce the issued share capital by cancelling shares or by amending the Articles of Association 
to reduce the nominal value of the shares. Only shares held by us or shares for which we hold the depositary receipts may be 
cancelled. A resolution of the shareholders at the General Meeting to reduce the number of shares must designate the shares to 
which the resolution applies and must lay down rules for the implementation of the resolution. A resolution to reduce the issued 
share capital requires a majority of at least two-thirds of the votes cast, if less than 50% of our issued and outstanding share capital 
is present or represented at the General Meeting.

5.4.  Dividend Policy

All of our outstanding Securities will have the same dividend rights. We intend to retain all available funds and any future earnings 
to fund the development and expansion of our business. 

Under Dutch law, a Dutch European public company with limited liability (Societas Europaea or SE) may only pay dividends if the 
shareholders’ equity (eigen vermogen) exceeds the sum of the paid-up and called-up share capital plus the reserves required to 
be maintained by Dutch law or our Articles of Association. Subject to such restrictions, any future determination to pay dividends 
would be at the discretion of the shareholders at our General Meeting. 

5.4.2.  ARTICLES OF A SS OCI ATI ON ON PRO F I T S, DI S TR I BU T I O N S AN D LOS S E S

Our articles of association contain the following provision on the distribution of profits:

Article 20. Profits, distributions and losses.
1. 

The company shall have a policy on reserves and dividends which shall be determined and may be amended by the board 
of directors. The adoption and thereafter each material change of the policy on reserves and dividends shall be discussed at 
the general meeting under a separate agenda item.
From the profits, shown in the annual accounts, as adopted, the general meeting shall determine which part shall be reserved. 
Any profits remaining thereafter shall be at the disposal of the general meeting. The board of directors shall make a proposal 
for that purpose. A proposal to pay a dividend shall be dealt with as a separate agenda item at the general meeting. 
Distribution of dividends on the shares shall be made in proportion to the nominal value of each share. 
If a loss was suffered during any one year, the board of directors may resolve to offset such loss by writing it off against a 
reserve which the company is not required to keep by virtue of the law.
The distribution of profits shall be made after the adoption of the annual accounts, from which it appears that the same is 
permitted.
The board of directors may, subject to due observance of the policy of the company on reserves and dividends, resolve to 
make an interim distribution. 
At the proposal of the board of directors, the general meeting may resolve to make a distribution on shares wholly or partly 
not in cash but in shares.
The board of directors may, subject to due observance of the policy of the company on reserves and dividends, resolve that 
distributions to holders of shares shall be made out of one or more reserves.

information concerning our board of directors and certain provisions of the Articles of Association and Board By-Laws (terms of 
reference) concerning our board of directors.

6.1.2.  GENERAL

The summaries of parts of our Articles of Association and By-Laws section 6.1 do not purport to give a complete overview and should 
be read in conjunction with, and are qualified in its entirety by reference to the relevant provisions of Dutch law as in force on the 
date of this Registration Document and the Articles of Association and Board By-Laws. The Articles of Association are available in 
the governing Dutch language and an unofficial English translation thereof, and the Board By-laws are available in English, on our 
website.

6.1.3.  DUTIES

Under Dutch law (Section 2:129 paragraph 1 of the DCC), our board of directors is collectively responsible for our general affairs. 
Pursuant to our Articles of Association, our board of directors will divide its duties among its members, with our day-to-day 
management entrusted to the executive directors. The board is responsible for the general affairs in the company and the business 
connected with it. The non-executive directors are tasked with supervising the management of the Company and providing the 
executive director with advice. In addition, both the executive director and the non-executive directors must perform such duties as 
are assigned to them pursuant to the Articles of Association. The division of tasks within our board of directors is determined (and 
amended, if necessary) by our board of directors. Each director has a duty to properly perform the duties assigned to him or her 
and to act in our corporate interest. As a principle under Dutch law, the corporate interest extends to the interests of all corporate 
stakeholders, such as shareholders, creditors, employees and other stakeholders. 

Our sole executive director, Tim Van Hauwermeiren, may not be allocated the tasks of: (i) serving as chairperson of our board of 
directors; (ii) determining his remuneration; or (iii) nominating directors for appointment. The executive director may not participate 
in the adoption of resolutions (including any deliberations in respect of such resolutions) relating to his remuneration. Certain 
resolutions of our board can only be adopted with the consent of a majority of the non-executive directors. 

6.1.4.  ROL E OF THE BOARD I N T HE ADO PTI O N AN D I M P LE ME N TAT I ON OF OUR S TR AT EGY

The board of directors, our executive director as well as our non-executive directors, define our strategy (as further set out in 
paragraph 3.1.2 “Strategy and Objectives” on page 58 of this Registration Document). Our strategy is regularly discussed and 
monitored at our board meetings, which take place by means of physical meetings (generally in Amsterdam, the Netherlands) or via 
teleconference facilities. For a description of the specific topics of responsibility of the board of directors and each of its committees, 
please refer to section 6.1 on page 144 and further.

6.1.5.  ROL E OF THE BOARD I N RI SK OVE RS I G HT

Our board of directors is responsible for the oversight of our risk management activities and has delegated to the audit committee 
the responsibility to assist our board in this task. While our board oversees our risk management, our management is responsible 
for day-to-day risk management processes. Our board of directors expects our management to consider risk and risk management in 

144  |  Our Board of Directors

each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and 
to effectively implement risk management strategies adopted by the board of directors. We believe this division of responsibilities 
is the most effective approach for addressing the risks we face.

6.1.6.  COMPOSITION, APPOINTMENT AN D DI S M I S S AL

The Articles of Association provide that our board of directors will consist of our executive director(s) and non-executive directors. 
The number of executive directors must at all times be less than the number of non-executive directors. The number of directors, 
as well as the number of executive directors and non-executive directors, is determined by our board of directors, with the proviso 
that the board of directors must consist of at least three members. 

Our directors are appointed by the shareholders at the General Meeting for a period of four years. In accordance with best practice 
principle 2.2.1 of the Dutch Corporate Governance Code, executive directors may be re-appointed for periods of not more than 
four years at a time. In accordance with best practice principle 2.2.2 of the Dutch Corporate Governance Code, non-executive 
directors are appointed for a period of four years and may subsequently be re-appointed for another four-year period, which 
appointment may be extended by at most two years. The board of directors is required to make one or more proposals for each 
seat on our board of directors to be filled. A resolution to nominate a director by our board of directors (with support from the 
remuneration and nomination committee) may be adopted by a simple majority of the votes cast. A nomination for appointment 
of an executive or non-executive director must state the candidate’s age and the positions he or she holds, or has held, insofar 
as these are relevant for the performance of the duties of an executive director. The nomination must state the reasons for the 
nomination of the relevant person. A nomination for appointment of a non-executive director must state the candidate’s age, his or 
her profession, the number of shares he or she holds and the employment positions he or she holds, or has held, insofar as these 
are relevant for the performance of the duties of a non-executive director. Furthermore, the names of the legal entities of which 
he or she is already a supervisory board member or a non-executive member of the board shall be indicated; if those include legal 
entities which belong to the same group, a reference to that group will be sufficient. The nomination must state the reasons for 
the nomination of the relevant person. 

Our directors are appointed as either an executive director or as a non-executive director by the shareholders at the General 
Meeting. Our board of directors designates one executive director as Chief Executive Officer. In addition, the board of directors may 
grant other titles to executive directors. Our board of directors designates a non-executive director as chairperson of the board of 
directors and a non-executive director as vice chairperson of the board of directors. The legal relationship between an executive 
member of the board of directors and the Company will not be considered as an employment agreement. Employment agreements 
between an executive director and a group company (other than argenx SE) are permitted. In the absence of an employment 
agreement, members of a board of directors generally do not enjoy the same protection as employees under Dutch labor law. 

Pursuant to the Articles of Association, a member of our board of directors will retire not later than on the day on which the first 
General Meeting is held following lapse of four years since his appointment. A retiring member of our board of directors may be 
re-appointed. 

Directors may be suspended or removed by the shareholders at the General Meeting at any time, with or without cause, by means 
of a resolution passed by a simple majority of the votes cast. Under Dutch law (Section 2:134 paragraph 1 of the DCC), executive 
directors may also be suspended by the board of directors. A suspension of an executive director by the board of directors may be 
discontinued by the shareholders at any time at the General Meeting. 

6.1.7.  COMMITTEES

In accordance with the Dutch Corporate Governance Code, our non-executive directors can set up specialized committees to analyze 
specific issues and advise the non-executive directors on those issues. 

The committees are advisory bodies only, and the decision-making remains within the collegial responsibility of the non-executive 
directors. The non-executive directors determine the terms of reference of each committee with respect to the organization, 
procedures, policies and activities of the committee.

I.

III. 
IV. 

an audit committee;
a remuneration and nomination committee;
a research and development committee; and 
a commercial committee. 

The composition and function of all of our committees complies with all applicable requirements of Euronext Brussels, the Dutch 
Corporate Governance code, the Exchange Act, the exchanges on which the ordinary shares are listed and SEC rules and regulations. 

Only non-executive directors qualify for membership of the committees. The audit committee and the remuneration and nomination 
committee may not be chaired by the chairperson of the board of directors or by a former executive director of the Company. 

6.1.8.  MEETING FREQUENCY AND DECI SI ON M AK I N G

Our board of directors has adopted rules (the Board By-Laws), that describe the procedure for holding meetings of the board of 
directors, for the decision-making by the board of directors and the board of directors’ operating procedures. 

In accordance with our Articles of Association, our board of directors will meet at least once every three months to discuss the state 
of affairs within the Company and the expected developments.

Under the Board By-Laws, the members of our board of directors must endeavour, insofar as is possible, to ensure that resolutions 
are adopted unanimously. Where unanimity cannot be achieved and Dutch law, the Articles of Association or the Board By-Laws 
do not prescribe a larger majority, all resolutions of our board of directors must be adopted by a simple majority of the votes cast 
in a meeting at which at least a majority of the members of our board of directors then in office are present or represented. The 
Articles of Association and the Board By-Laws provide that in case of a tie of votes, the chairperson does not have a casting vote 
and as such the proposal will be rejected in case of a tie. 

Under the Board By-Laws, some specific matters require approval of the majority of the non-executive directors. These matters are 
set out in Schedule 1 of our Board By-Laws. Our board By-Laws are available on our website.

In exceptional cases, if the urgent necessity and the interests of the Company require this, resolutions of our board of directors 
may also be adopted by unanimous written approval of all directors in office. 

A director may issue a proxy for a specific board meeting to another director in writing. At the date of this Registration Document 
there are no other executive directors in office. 

6.1.9.  I NDE P E NDENC E OF TH E BOAR D O F DI R ECTO R S AN D CO M M I TTE E M EM B E R S

As a foreign private issuer, under the listing requirements and rules of Nasdaq, we are not required to have independent direc-
tors on our board of directors, except that our audit committee is required to consist fully of independent directors, subject to 
certain phase-in schedules. However, our board of directors has determined that, under current listing requirements and rules of 
Nasdaq and taking into account any applicable committee independence standards, all of our non-executive directors, including the 
members of our audit committee, are “independent directors” under Rule 10A-3 of the Exchange Act and the applicable rules of the 
Nasdaq Stock Market and all members of our audit committee are independent under the applicable rules of the Dutch Corporate 
Governance Code. In making such determination, our board of directors considered the relationships that each non-executive 
director has with us and all other facts and circumstances our board of directors deemed relevant in determining the director’s 
independence, including the number of ordinary shares beneficially owned by the director and his or her affiliated entities (if any). 

The Dutch Corporate Governance Code requires that the composition of the non-executive directors is such that the members are 
able to operate independently and critically vis-à-vis one another, the executive directors, and any particular interests involved. At 
the date of this Registration Document, all non-executive directors meet the independence criteria contained in the Dutch Corporate 

146  |  Our Board of Directors

Governance Code. Therefore, in the opinion of the non-executive directors, the composition of our non-executive directors complies 
with the independence requirements of best practice provisions 2.1.7 to 2.1.9 of the Dutch Corporate Governance Code. Our board 
of directors has consequently also determined that all members of our committees are independent under the applicable rules of 
the Dutch Corporate Governance Code. 

As of the date of this Registration Document (or in any period before), none of the members of our board of directors and executive 
management has or has had a family relationship with any other member of our board of directors or executive management. 

6.1.10. CONFIRMAT ION OF NO PAST OFFE N SE S

As of the date of this Registration Document and except as set out below, none of the members of our board of directors and 
executive management for at least the previous five years:

•  has been convicted of any fraudulent offenses; 
•  has been a senior manager or a member of the administrative, management or supervisory bodies of any company at the time 

of or preceding any bankruptcy, receivership, liquidation or of such company being put into administration; 

•  has been subject to any official public incrimination and/or sanction by any statutory or regulatory authority (including any 

designated professional body); or 

•  has ever been disqualified by a court from acting as a member of the administrative, management or supervisory bodies of any 

company or from acting in the management or conduct of affairs of any company. 

6.1.11.  DIVERSITY

Currently, less than 30% of our board of directors consists of female directors. Our policy is that we will balance our board of 
directors in terms of gender, as well as age, background and nationality as much as reasonably possible while still having our board 
composed of the best possible candidates overall. It has been and will remain our priority to have the best available specialists on our 
board of directors, irrespective of age, background, nationality and gender, who make a balanced panel of directors able to advise 
and guide our Company to further growth and success for all its stakeholders. This means we require a number of specialties and 
character traits to be present. Taking into account the aforementioned and the specialist nature of our business, we will actively seek 
to further improve diversity on our board if and when proposing new appointments to our board of directors, whilst acknowledging 
that gender is one of many factors that is relevant in the ultimate decision to select a board member or not.

In the calendar year 2019, Mr. Don deBethizy was reappointed to our Board of Directors. No other appointments were made. 

6.1.12. LIABILITY OF BOARD MEMBERS

Under Dutch law (Section 2:138 of the DCC), members of our board of directors may be liable to us for damages in the event of 
improper or negligent performance of their duties. They may be jointly and severally liable for damages to us and third parties for 
infringement of the Articles of Association or certain provisions of the Dutch Civil Code, or DCC. In certain circumstances, they may 
also incur additional specific civil and criminal liabilities. 

The liability of members of our board of directors and executive management is covered by a directors’ and officers’ liability insur-
ance policy. This policy contains customary limitations and exclusions, such as wilful misconduct or intentional recklessness (opzet 
of bewuste roekeloosheid). In addition, according to article 15 of our Articles of Association, we will indemnify our directors against 
liabilities, claims, judgements, fines and penalties in relation to acts or omissions in or related to his or her capacity as director.

6.1.13. CONFLI CT-OF-INTEREST TRAN SACTI ON S

Directors will immediately report any (potential) direct or indirect personal interest in a matter which is conflicting with the interests 
of the company and the business connected with it to the chairperson of our board of directors and to the other directors and will 
provide all relevant information, including information concerning their spouse, registered partner or other partner, foster child and 
relatives by blood or marriage up to the second degree as defined under Dutch law (Section 1:3 paragraph 1 of the DCC). 

Our Board of Directors    |  147 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCEThe non-executive directors will decide, without the director concerned being present, whether there is a conflict of interest. A 
conflict of interest in relation to a director in any event exists if we intend to enter into a transaction with a legal entity (i) in which 
such director personally has a material financial interest, (ii) which has an executive director or a member of the management 
board who is related under family law to such director or (iii) in which such director has an executive or non-executive position. A 
director will not participate in any discussions and decision making if he has a conflict of interest in the matter being discussed. If 
for this reason no resolution can be taken by our board of directors a whole, the shareholders at a General Meeting will resolve on 
the matter. All transactions in which there are conflicts of interest with directors will be agreed on terms that are customary in the 
sector concerned. Decisions to enter into transactions in which there are conflicts of interest with directors that are of material 
significance to us or to the relevant director require the approval of the non-executive directors. All transactions between us and 
legal or natural persons who hold at least one tenth of our shares will be agreed on terms that are customary in the sector in which 
we and our combined businesses are active. The non-executive directors are required to approve such transactions that are of a 
material significance to us or to such persons. 

There are no arrangements or understandings in place with major shareholders, customers, suppliers or others pursuant to which 
any member of our board of directors or executive management has been appointed. There are no conflicts of interests between 
the Company and any administrative, management and supervisory bodies and senior management, nor are there any potential 
conflicts of interests between any duties to the Company, the members of our board of directors and executive management and 
their private interests and or other duties.

6.1.14. CODE OF BUSINESS CONDUCT AN D ET H I CS

We adopted a Code of Business Conduct and Ethics, or the Code of Conduct, that is applicable to all of our employees and directors. 
The Code of Conduct is available on our website at www.argenx.com. The audit committee of our board of directors is responsible 
for overseeing the Code of Conduct and is required to approve any waivers of the Code of Conduct for employees and directors. 
We expect that any amendments to the Code of Conduct, and any waivers of its requirements, will be disclosed on our website.

6.3.1.  EXECUTIV E MAN AGEMENT TEAM O R E XEC U TI V E COM MI TT EE

We have an executive management team consisting of our senior management. Of these persons, only our CEO, Mr. Tim Van 
Hauwermeiren, is part of our statutory board of directors. We have opted for this structure to allow for a division of responsibilities 
between our board of directors and our executive management team, keeping our board of directors at a manageable size whilst 
being able to involve some or all members of our executive management team on discussions of the board if and when necessary.

In practice, all members of our executive management team are regularly involved in the discussions of our board of directors and 
its committees, in order to provide information and context to the various issues the board needs to decide on. In addition to being 
present to meetings from time to time, regular contact (face to face or via electronic means) is kept between the members of the 
board of directors and its committees and the members of the executive management team.

6.4.  Dutch Corporate Governance Code, “Comply or Explain”

6.4.1.  GENERAL

The Dutch Corporate Governance Code contains both principles and best practice provisions for management boards, supervisory 
boards, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and enforcement 
standards. A copy of the Dutch Corporate Governance Code can be found on www.corpgov.nl. As a Dutch company, we are subject 
to the Dutch Corporate Governance Code and are required to disclose in our annual report, filed in the Netherlands, whether 
we comply with the provisions of the Dutch Corporate Governance Code. If we do not comply with the provisions of the Dutch 
Corporate Governance Code (for example, because of a conflicting Nasdaq requirement or otherwise), we must list the reasons for 
any deviation from the Dutch Corporate Governance Code in our annual report. 

We acknowledge the importance of good corporate governance. However, at this stage, we do not comply with all the provisions of 
the Dutch Corporate Governance Code, to a large extent because such provisions conflict with or are inconsistent with the corporate 
governance rules of Nasdaq and U.S. securities laws that apply to us, or because such provisions do not reflect best practices of 
global companies listed on Nasdaq.

160  |  Dutch Corporate Governance Code, “Comply or Explain”

6.4.2.  COMPLY-OR EXPLAIN

We fully endorse the underlying principles of the Dutch Corporate Governance Code which is reflected in a policy that complies with 
the best practice provisions as stated in the Dutch Corporate Governance Code. However, we do not (yet) comply with or deviate 
from the best practice provisions in the following areas:

•  We do not comply with best practice provisions 2.1.5 and 2.1.6 of the Dutch Corporate Governance Code. Best practice provi-
sion 2.1.5 requires that the non-executive directors shall draw up a diversity policy for the composition of the board and best 
practice provision 2.1.6 requires that we explain how we are currently applying such policy. We fully recognize the importance 
of diversity and promote an inclusive culture, but utilize other means than a diversity policy in pursuit of the same goals (e.g. 
our board profile includes the objective to achieve a diverse composition with respect to nationality, experience, background, 
age and gender). As we have not drawn up the policy, we also do not report on our application thereof. We currently do not 
envision to change our practices in this respect. 

•  We do not comply with best practice provision 2.3.2 of the Dutch Corporate Governance Code, which requires that our non-ex-
ecutive directors appoint among its members an audit committee, a remuneration committee and a selection and appointment 
committee. Our remuneration committee and the selection and appointment committee are combined into a single committee, 
being the remuneration and nomination committee. This committee performs the tasks attributed by the Dutch Corporate 
Governance Code to the remuneration committee, as well as the tasks attributed by the Dutch Corporate Governance Code to 
the selection and appointment committee. Hence, the combination of these committees is an organizational matter only and 
we believe we achieve the objectives of this best practice provision through a single committee. We currently do not envision 
to change our practices in this respect. 

•  We do not comply with best practice provisions 3.1.2 under vii of the Dutch Corporate Governance Code, which states that 
options are not to be exercised within the first three years after the date of granting. Pursuant to our option plan, options are 
exercisable once vested, which means that one third of the options granted are exercisable after one year, and each month 
after one-twenty-fourth of the remaining options is exercisable. Our option plan was crafted recognizing that equity incentives 
are an important factor in the market for attracting and retaining qualified staff. Hence, we deviate from best practice provision 
3.1.2 under vii to allow for a liquid and hence competitive option plan. At the same time, we believe our current option plan 
promotes long term value creation. For instance, the three year vesting period ensures that an option package granted cannot 
be fully exercised within three years after the grant date. Until the date of this Registration Document, none of the directors 
have exercised any options within the first three years after the date of grant of those options. The Option Plan is regularly 
reviewed by the board of directors and the remuneration and selection committee in particular, the main purpose of such review 
is to test if the Option Plan is sufficiently contributing to our ability to attract and retain talent. In 2019, our shareholders have 
re-approved our updated stock option plan, including the aforementioned vesting schemes. We currently do not expect such 
reviews will be geared at achieving full compliance with the Dutch Corporate Governance in this respect. 

•  We do not comply with best practice provision 3.2.3. of the Dutch Corporate Governance Code, which requires that the sever-
ance payment in the event of dismissal should not exceed one year’s base salary. As further explained in the section Related 
Party Transactions – Agreements with Our Executive Management, the agreement of our chief executive officer stipulates that 
a severance payment equal to 18 months base salary may become payable by the Company to our chief executive officer. The 
severance component of the remuneration package is, like all other components and in accordance with our remuneration 
policy as approved by the General Meeting, benchmarked against and aligned with the severance components as identified 
within the reference group. On this particular topic, considering the importance of competitive remuneration for our ability 
to attract and retain highly qualified persons, alignment with the reference group is prioritized over compliance with this best 
practice provision 3.2.3. We currently do not envision to change our practice in this respect.

•  We do not comply with best practice provision 3.3.2. of the Dutch Corporate Governance Code, which requires that non-exec-
utive directors will not be granted any shares or rights to shares as remuneration. In accordance with our remuneration policy, 
non-executive directors may be granted options by way of remuneration, in recognition of the substantial industry expertise 
they bring to us. Our remuneration policy, as was presented to and approved by the General Meeting, and this equity element 
for non-executive directors in particular are geared at a fair but competitive compensation package and takes a number of 
relevant benchmarks into account. We currently do not envision to change our practice in this respect. 

•  We do not comply with best practice provision 2.3.1, which requires our board rules to contain a section on the interaction 
between the board of directors and the executive committee. We have not revised our board rules since we have established 
that we use an executive committee within the meaning of best practice provision 2.3.1. We expect to update our policy in 
this regard, and also to reflect the incorporation of our commercial committee, in the financial year ending 31 December 2020.

OF THE NASDAQ S TOCK MARKET

We are in the United States considered a foreign private issuer. As a result, in accordance with the listing requirements of Nasdaq, 
we may rely on home country governance requirements and certain exemptions thereunder rather than relying on the corporate 
governance requirements of Nasdaq. In accordance with Dutch law and generally accepted business practices in the Netherlands, 
our Articles of Association do not provide quorum requirements generally applicable to general meetings of shareholders. To this 
extent, our practice varies from the requirement of Nasdaq Listing Rule 5620(c), which requires an issuer to provide in its bylaws 
for a generally applicable quorum, and that such quorum may not be less than one-third of the outstanding voting stock. Although 
we must provide shareholders with an agenda and other relevant documents for the General Meeting, Dutch law does not have 
a regulatory regime for the solicitation of proxies, and the solicitation of proxies is not a generally accepted business practice in 
the Netherlands; thus, our practice will vary from the requirement of Nasdaq Listing Rule 5620(b). In addition, we have opted out 
of certain Dutch shareholder approval requirements for the issuance of securities in connection with certain events, such as the 
acquisition of stock or assets of another company, the establishment of or amendments to equity-based compensation plans for 
employees and a change of control of us and certain private placements. To this extent, our practice varies from the requirements 
of Nasdaq Rule 5635, which generally requires an issuer to obtain shareholder approval for the issuance of securities in connection 
with such events.

6.4.4.  EVALUATION PROCESS

The board evaluates the functioning of the board of directors, its committees and of each individual director annually. This is 
done on the basis of prepared questionnaires, which are completed by each board member and collected by the chairman of the 
board. On the basis of an analysis of the outcome of the questionnaires, key topics are discussed with individual directors and/or 
by the board or the relevant committees. In 2019, among other things, the evaluations have led to the decision to implement the 
commercial committee.

6.5.  Risk appetite & control

Before reading the rest of this section 6.5, please carefully review the following cautionary statement:

IN THIS SECTION 6.5 WE WILL MAKE THE REQUIRED DISCLOSURES REGARDING OUR RISK APPETITE AND 
MITIGATING ACTIONS. THE RISK MITIGATION ACTIONS AND RISK MANAGEMENT DESCRIBED IN THIS SECTION 
6.5 HAS BEEN FULLY TAKEN INTO ACCOUNT BY US WHEN PREPARING THE DESCRIPTION OF THE MAIN RISKS AND 
UNCERTAINTIES WE FACE, AS SET OUT IN CHAPTER 1 “RISK FACTORS”. ANY MITIGATING LANGUAGE USED IN THIS 
SECTION 6.5 DOES NOT HAVE ANY IMPACT ON THE RISKS AND UNCERTAINTIES WE FACE OR THEIR POTENTIAL 
ADVERSE EFFECTS AS THEY ARE DESCRIBED IN CHAPTER 1 “RISK FACTORS”. 

CHAPTER 1 “RISK FACTORS” DESCRIBES THE MAIN RISKS AND UNCERTAINTIES WE FACE ALREADY FULLY HAVING 
TAKEN INTO ACCOUNT OUR RISK MANAGEMENT AND THE RISK MITIGATING ACTIONS DESCRIBED HEREIN.

6.5.1.  I NTRO DUCTION

This Registration Document, in application of article 9 sub 12 of EU Regulation 2017/1129 (or the Prospectus Regulation) contains 
(whether in the body of the document or in the documents incorporated by reference) the information required for us to be 
disclosed in our annual financial reporting and as such also serves as our annual report for the financial year 2019. 

Under Dutch law, we are required to include in our annual report a general description of our willingness to mitigate the risks and 
uncertainties we face (also called our ‘risk appetite’), and to give a description of the mitigating actions we have taken with regard 
to our most relevant risks. 

162  |  Risk appetite & control

6.5.2.  GENERAL DESCRI PT ION OF OUR RI SK APP ETI T E

Our risk appetite serves as a guideline for us in deciding which measures we may take in mitigating some of the risks and uncer-
tainties we face. Our risk appetite is aligned with our strategy and priorities. The business we operate in is inherently high-risk. In 
general, we are willing, and in our view required, to take significant risks to be able to operate successfully in our line of business. 
Some of the risks and uncertainties we face are entirely outside of our control whereas others may be influenced or mitigated.

6.5.3.  CONTROLLING AC TIONS TAKEN BY U S W I TH R EGAR D TO OU R M OS T R E LE VAN T R I S K S AND 

UNCERTAI NT IES

As required by Clause 2:391 sub 1 of the Dutch Civil Code in conjunction with Guideline 400.1.110c on Annual Reporting, the 
following is a description of the main risks and uncertainties we face (being the first risk of each category of risk factors set out in 
Chapter 1 “Risk Factors”) and a description of the measures we took to control them. A description of the expected impact upon 
materialization of these risks is included for each risk in Chapter 1 “Risk Factors”.

MEASURES TAKEN TO CONTROL THESE RISKS

We have incurred significant losses since our inception and expect to incur losses 
for the foreseeable future. We may never achieve or maintain profitability. 

All of our product candidates are in preclinical, early-stage clinical or clinical de-
velopment.  Our  trials  may  fail  and  even  if  they  succeed  we  may  be  unable  to 
commercialize any or all of our product candidates due to a lack of, or delay in, 
regulatory approval or for other reasons.

Enacted and future legislation may increase the difficulty and cost for us to obtain 
marketing approval of and commercialize our product candidates and may affect 
the prices we may set.

Our product candidates may not fulfill regulatory compliance. 

Nearly all aspects of our activities are subject to substantial regulation. No assur-
ance can be given that any of our product candidates will fulfill regulatory com-
pliance. 

We rely, and expect to continue to rely, on third parties, including independent 
clinical investigators and CROs, to conduct our preclinical studies and clinical tri-
als. 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 rely on patents and other intellectual property rights to protect our product 
candidates and the SIMPLE AntibodyTM, NHance® and ABDEGTM platform tech-
nologies, the enforcement, defense and maintenance of which may be challeng-
ing and costly. Failure to enforce or protect these rights adequately could harm 
our ability to compete and impair our business. 

Our future growth and ability to compete depends on retaining our key personnel 
and recruiting additional qualified personnel.

We have adopted a business model and strategic portfolio management approach 
to spread risks over wholly-owned programs as well as partnered programs, and 
to  manage  risks  within  our  own  proprietary  product  candidates  pipeline.  We 
continue to create novel, differentiated product candidates from our proprietary 
technology platforms which regularly feed our product candidate pipeline.

We  may  seek  orphan  drug  designations  that  can  potentially  reduce  regulatory 
approval risk. We have a strategy in place to have discussions with regulatory ex-
perts at the EMA, FDA and PDMA, as well as its consultants and CROs.

We  endeavor  to  meet  our  contractual  obligations  and  any  relevant  milestone 
achievements under our collaboration contracts. We endeavor to maintain a rich 
pipeline of possible collaboration partners as well as a good relationship with ex-
isting and potential future collaboration partners in order to limit reliance on a 
limited number of collaboration partners.

We file and prosecute patent applications to protect our product candidates and 
technologies. We are doing this in close collaboration with leading expert firms 
in the field of intellectual property protection. In order to protect trade secrets, 
we  maintain  strict  confidentiality  standards  and  agreements  with  collaborating 
parties. We regularly monitor third party intellectual property rights within our 
relevant fields and jurisdictions to avoid violating any third-party rights and se-
cures licenses to such third-party rights on a need-to basis.

We offer competitive remuneration packages and share based incentives in the 
form  of  our  employee  stock  option  plan.  We  perform  periodical  benchmark 
analyses with an external service provider to ensure the competitiveness of the 
compensation offered to our key personnel in comparison to other (peer group) 
companies. We pay close attention to creating an environment that supports the 
further development of the talents of our key people.

6.5.4.  MATERIAL I MPACT OF RISK MATER I AL I ZAT I O N I N 2019

In the period between January 1 2019 and the date of this Registration Document, we have not identified any material impact on 
the Company as a result of materialization of previously identified risks and uncertainties.

In running our business, we seek to implement a sustainable policy regarding internal control and risk management. Our Board 
of Directors has delegated an active role to its Audit Committee in the design, implementation and monitoring of an internal risk 
management and control system to manage the significant risks to which we are exposed.

Our financial reporting is structured within a tight framework of budgeting, reporting and forecasting. A distinction is made between 
reports for internal and external use. External reporting at group level consists of an annual report (in the form of this Registration 
Document), including financial statements audited by the external auditor, as well semi-annual reporting and quarterly updates, 
containing summarized financial information. The external reports are based on the internal financial reporting.

Internal financial reporting consists of extensive consolidated monthly reports in which current developments are compared to the 
monthly (cumulative) budgets and previous forecasts. In addition, each quarter we reiterate or update our forecast for the annual 
results, including the cash flow position at the end of the financial year. The quarterly budgets are part of the annual group budget, 
which is prepared every year by our executive management and approved by our Board of Directors. Our specialized finance and 
administration department are primarily responsible for evaluating the draft internal and external reporting, before these are finally 
approved by our Board of Directors.

The Board of Directors discusses the financial results of the group at all formal board meetings, which meetings are minuted. 

The company’s internal controls over financial reporting are a subset of internal controls and include those policies and procedures 
that:

I. 

II. 

III. 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 
of the assets of the company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with IFRS as adopted by the EU, and that receipts and expenditures of the company are being made only by 
authorized persons; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the 
company’s assets that could have a material effect on the financial statements.

Since the company has securities registered with the U.S. Securities and Exchange Commission, or SEC and is a large accelerated 
filer within the meaning of Rule 12b-2 of the U.S. Securities Exchange Act of 1934, the company needs to assess the effectiveness 
of the internal controls over financial reporting and provide a report on the results of this assessment. The Company has reviewed 
its internal controls over financial reporting based on criteria established in the Internal Control – Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and engaged an external advisor to help 
assess the effectiveness of those controls.

6.5.6.  REC E NT OR CURRENT DEVELOPMENT S I N O U R SYS T EM O F R I S K MAN AG E M EN T

In 2019, we have created and hired the position of internal controls manager within the Company directly reporting to our CFO. 
The internal controls manager is responsible for the evaluation of the adequacy of the design and operating effectiveness of the 
Company’s internal controls and processes through risk assessments, walkthroughs, testing of controls, continuous monitoring of 
control compliance and reporting the results to our CFO and subsequently the Audit Committee. Our internal controls manager is also 
responsible for the promotion of a risk-aware culture and to ensure efficient and effective risk and compliance management practices.

6.6.  Compensation Statement and Remuneration Report

This section 6.6 contains the compensation statement required by article 2:135b of the Dutch Civil code and the remuneration 
report required by the Dutch Corporate Governance Code.

164  |  Compensation Statement and Remuneration Report

6.6.1.  REMUNERATION POLIC Y

General
Our remuneration policy sets out that the remuneration of our executive and non-executive director(s) shall be determined by 
the board of directors. The Remuneration and Nomination Committee monitors and at least annually re-evaluates whether the 
remuneration policy is still suitable for the Company’s purposes and proposes adjustments where necessary. The remuneration 
policy was last updated and approved by our general meeting on 7 November 2017. Every other year, our board also evaluates the 
appropriateness of any change of total target cash compensation in the context of the market environment as well as the salary 
adjustments for other employees of the Company. Based on the outcome of the benchmarking analysis described above, the 
Remuneration and Nomination Committee is implementing step-by-step adjustments of the remuneration packages to ensure that 
the remuneration offered is in line with the remuneration policy, prescribing a remuneration in line with (or slightly above) market 
practice (determined as around or slightly above the 75th percentile salary level within the European companies of the peer group 
and the 50th percentile salary level of US based companies of the peer group). Ensuring a market conform salary will enable us to 
attract and retain the qualified individuals on which, largely, our success depends. At all times when deciding on the remuneration 
of our key persons (including senior management and board members), scenario analyses are made and duly taken into account.

Amendments
The last benchmarking exercise was done mid-2018, with the assistance of external experts. Following such benchmark and taking 
into account the entry into force changes in Dutch legislation during 2019 and early 2020 pursuant to Directive (EU) 2017/828 of 
the European Parliament and of the Council of 17 May 2017 amending Directive 2007/36/EC as regards the encouragement of 
long-term shareholder engagement or shareholder rights directive, setting out various new and amended requirements for the way 
remuneration policies are drawn up, we expect to update our remuneration policy and present a new version of it to our annual 
general meeting in 2020.

Contribution of the remuneration policy to the Company’s long-term value creation
The policy governing the remuneration of our board of directors and key personnel is aimed to attract, reward and retain highly 
qualified persons and to provide and motivate the members of the board and the senior management with a balanced and compet-
itive remuneration that is focused on sustainable results and is aligned with the long-term strategy of the Company as set out in 
our business plan. 

Our Company has never been profitable and is also not expected to be profitable within the foreseeable future. As a result, the 
performance targets set for our management team are not aimed at short term goals such as share value or turnover, but are 
instead directly or indirectly targeted at achieving or enabling the further development of our product candidates and generally at 
the further development and expanding of the organization as a whole. 

Part of the remuneration of our management team consists of stock options, which are granted annually and have a vesting period 
of three years. The vesting period and corresponding offering obligations are aimed at retaining our personnel and creating an 
incentive for long term value creation in the process. 

6.6.2.  COM PE NSATION OF OUR EXECU TI V E M AN AGEM EN T

The remuneration of our executive management (including our executive director) consists of the following fixed and variable 
components:

•  a fixed base salary; 
•  an annual variable pay (short-term annual cash incentive); 
• 
• 
•  pension and fringe benefits.

long-term variable incentive awards, in the form of stock options; 
severance arrangements; and

Compensation Statement and Remuneration Report    |  165 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCEFixed base salary.
The base salary of our executive management was determined on the basis of a benchmarking analysis completed by an independent 
consulting firm. In accordance with this benchmarking analysis, our board of directors has resolved to aim for a compensation of our 
executive management in the 75th percentile of the compensation offered by the European peer group for executive management 
living in Europe and 50th percentile offered by the US peer group for executive management living in US, each time as identified 
by the independent consulting firm used in this analysis. The base salary of the executive director will be determined at a range 
around the median salary levels payable within a blend of both European and US peer group.

Variable annual cash bonus.
The objective of this short-term annual cash incentive is to ensure that our executive management is incentivized to achieve 
performance targets in the shorter term. Our executive management is eligible for an annual cash incentive up to a maximum 
percentage of his/her annual base salary. The maximum percentage for this purpose was set at 50% of base salary of the chief 
executive officer, 40% of base salary of the Chief Operating Officer and at 35% of base salary for other members of the executive 
management. Performance conditions are established by our board of directors before or at the beginning of the relevant calendar 
year and shall include criteria concerning our financial performance, qualitative criteria representing our performance and/or 
individual qualitative performance. 

Long-term incentive awards.
Our board of directors intends to incentivize our executive management by issuing options from time to time to be able to attract 
and retain well-qualified executive management in connection with the Option Plan, as set out below. Typically, options are granted 
annually in accordance with out stock option grant scheme which is regularly reviewed by our board of directors and particularly 
our remuneration and nomination committee.

Severance arrangements.
We have entered into management contracts and employment agreements with our executive management, each of which provides 
for certain minimum notice periods if their service or employment with us is terminated in certain circumstances as described below 
in paragraph 6.6.5 “Related party transactions”. 

Pension and fringe benefits.
Our executive management participates in a defined contribution pension scheme operated by a third-party pension insurance 
organization. Our executive management is entitled to customary fringe benefits, such as a company car and a hospitalization plan. 

Performance of scenario analyses
In determining the remuneration package of each individual member of the management team, scenario analyses are performed 
annually and taken into account in setting the level of the base remuneration to be paid as well as the variable remuneration and 
the corresponding targets.

Relations between the remuneration of executives in comparison to lower level company personnel
The total company expense for the non-equity remuneration paid to our chief executive officer (and only statutory executive director) 
for the year ended 31 December 2019, equalled EUR 851,288, representing 784% of the total company expense for the non-equity 
median salary paid to our employees. This percentage was calculated on the basis of the last salary payment period of the year 
ended 31 December 2019, over which the median non-equity remuneration of all Company employees relative to their full time 
percentage was taken into account and set off against the non-equity remuneration of our executive director for the same period. 
We calculate the aforementioned percentage on the last salary payment of the relevant period, because due to our rapid growth 
we deem it relevant to also include our latest hires in the comparison, which includes a number of persons who are not (primarily) 
working at our facilities in Gent, Belgium.

Annual change of compensation, of the performance of the Company and of average remuneration on a full-time equivalent basis 
of employees of the Company other than executive directors over the five most recent financial years:

The decrease in the remuneration ratio between our key executives and other employees between 2018 and 2019 is caused by the 
increased median salary paid to our employees, mainly as a result of our expansion in the U.S.

The comparison of non-equity salary above is made between the salary paid to our single executive director, and the median salary 
paid to our employees. We have opted to compare non-equity salaries in this comparison, because whereas the number of options 
granted is linked to the overall size of remuneration packages granted, the value of equity components depends on the evolvement 
of our share price, which is unknown at granting and as such the forward looking valuation methods for options normally do not 
provide an accurate economic value.

Due to the global spread of our employees over multiple continents, we deem it relevant to also include the above comparison 
separately to our US Employees, EU Employees and Japan employees. Due to the overall higher salary level in our business segment 
in the US and Japan compared to Europe, there is a significant difference in the pay ratio when the CEO’s salary is compared to 
the median salary of all our employees (the majority of which are EU persons), as set out above, or compared to employees in the 
United States and Japan. The following information is provided for reference purposes:

The manner in which the variable pay of our executive director contributes to the long term value creation of the 
Company
As a result of linking long term targets, designed to increase the Company’s performance in the present as well as the future, to the 
variable pay of our management intends to align the interests of the management team to that of the (other) stakeholders in the 
Company. The board believes that a remuneration package comprised of a cash salary as well as options linked to a vesting scheme 
and a variable pay linked to individual targets is most suitable to achieve this goal.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCE6.6.3.  COMPENSATION OF OUR NON-EXECU TI V E D I R EC TO R S

The remuneration of the individual members of the board of directors is determined by the non-executive directors, at the recom-
mendation of the remuneration and nomination committee, within the limits of the remuneration policy adopted by the share-
holders at the General Meeting. The description below reflects the status of our remuneration policy as updated by our board of 
directors on September 12, 2017 and giving effect to the update to the remuneration policy approved by our shareholders at the 
extraordinary shareholders’ meeting held on November 7, 2017.

Pursuant to the remuneration policy, the remuneration of the non-executive directors consists of the following fixed and variable 
components:

•  a fixed fee, which fee will be prorated if the non-executive director does not attend all meetings where his or her presence is 

• 

required; 
if applicable, a fee for chairing the audit committee, the research and development committee or the remuneration and 
nomination committee; 

•  a fixed fee for board committee membership; and 
•  a long-term variable incentive in the form of stock options. 

Fixed fee.
The board of directors has set the annual base remuneration for non-executive directors at €35,000, additional remuneration for 
the chairperson of the board of directors at €30,000, additional remuneration for the chairperson of the audit committee and the 
research and development committee of the board of directors at €15,000 and additional remuneration for the chairperson of the 
remuneration and nomination committee and the commercial committee of the board of directors at €10,000. Board committee 
members, other than the chairman of the relevant committee, receive an annual retainer of €5,000 for the remuneration and 
nomination committee and a €7,500 retainer for the members of the audit committee and the research and development committee.

Long-term incentive plan.
The board of directors intends to incentivize the non-executive directors by issuing options from time to time to be able to attract 
and retain well-qualified non-executive directors in connection with the Option Plan. The board of directors grants options to the 
non-executive directors on the recommendation of the remuneration and nomination committee. Such option grants are based on 
an option allocation scheme established by the board of directors pursuant to the Option Plan. The conditions of our option plan 
apply to our non-executive directors, as set forth in paragraph 6.6.4 “Long-Term Incentives Granted to Key Persons - Option Plan”.

Success payment.
In exceptional circumstances, the board of directors may decide to reward a non-executive director with a success payment relating 
to the occurrence of specific events achieved through the exceptional efforts of that person (such as a platform licensing or product 
licensing deal brokered by that non-executive director). To date, no such success payments have been made or promised by us to 
our non-executive directors.

Pursuant to the remuneration policy, in case of a dismissal, non-executive directors will not be entitled to a severance payment.

6.6.4.  LONG-TERM I NC ENTIVES GRAN TE D TO KEY P E R S ON S - O P TI O N PLAN

On December 18, 2014, our board of directors adopted an employee stock option plan, or the Option Plan, which was approved by 
the shareholders at the General Meeting on May 13, 2015 and amended by the General Meeting on April 28, 2016. The aim of the 
Option Plan is to encourage our executive management, directors and key outside consultants and advisors to acquire an economic 
and beneficial ownership interest in the growth and performance of the Company, to increase their incentive to contribute to our 
value and to attract and retain individuals who are key to our Company. 

The Option Plan has been amended by the board of directors and approved by our General Meeting on November 25, 2019. The 
following amendments have been made:

• 
• 
• 

the terms of the Option Plan are updated to reflect the latest changes in applicable laws, including the Market Abuse Regulation;
specific provisions governing the granting of ‘sign-on-options’ for attracting new (key) personnel are added; and
the Option Plan now contains a description of the method the Company applies for determining the amount of options to grant 
to key persons which is based on transparent and objective option allocation scheme. 

In connection with the Option Plan, our board of directors has also established an option allocation scheme. The option allocation 
scheme contains (i) the date on which options are granted each year, which shall be the same date each year and (ii) the number 
of options granted to each person or to each group of persons, which shall be based on objective criteria only. 

Our board of directors, in each case subject to the approval of the majority of the non-executive directors, may grant options to 
our executive management, directors or key outside consultants or advisors and in accordance with the option allocation scheme. 
Our board of directors may also grant options at its discretion outside of the option allocation scheme, but only in a period when 
no inside information (as specified in our insider trading policy) is available. Persons to whom options are granted cannot refuse 
to accept such options. 

The aggregate number of shares that may be available for the issuance of options is equal to 14.5% of our fully diluted share capital. 
Shares issued pursuant to the exercise of an option are counted towards the share capital, and options that cease to exist (whether 
through exercise, termination or otherwise) are restored to the foregoing limit and shall again be available for issuance under the 
Option Plan. Shares shall be charged against the forgoing limit upon the grant of each option, but if such shares are thereafter 
forfeited or such option otherwise terminates without the issuance of such shares or of other consideration in lieu of such shares, 
the shares so forfeited or related to the terminated portion of such option shall be restored to the foregoing limit and shall again 
be available for options under the Option Plan. 

Options granted pursuant to the Option Plan shall vest with respect to one third of the shares upon the first anniversary of the 
date of grant, with the remaining two thirds vesting in twenty-four equal monthly instalments with the option fully vesting upon 
the third anniversary of the date of grant, subject, in each case, to the optionee’s continued status. Options are exercisable when 
vested, and in any case not after the option expiration date included in each individual option grant, which is (at the election of the 
optionee) either 5 years or 10 years from the date of grant. 

Compensation Statement and Remuneration Report    |  181 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCE    
Each option shall be granted with an exercise price equal to the fair market value upon the date of grant and shall have a term 
equal to five or ten years from the date of grant. Optionees may prefer to elect the 5 year period as this may limit their personal 
tax obligations in respect of the option, compared to a 10 year option. In the case of a (i) sale, merger, consolidation, tender offer 
or similar acquisition of shares or other transaction or series of related transactions as a result of which a change in control occurs, 
(ii) sale or other disposition of all or substantially all of the Company’s assets or (iii) dissolution and/or liquidation of the Company, 
then 100% of any unvested options shall vest. 

Our board of directors, upon approval of a majority of the non-executive directors may amend or terminate the Option Plan or may 
amend the terms of any outstanding options, provided that no amendment or termination may affect any existing rights without 
the consent of the affected optionees.

6.6.5.  RELATED PART Y TRAN SACTION S

Since 31 December 2019, being the end of the last financial period for which audited financial statements have been published, we 
have not entered into any transactions with any related parties which are – as a single transaction or in their entirety – material to us.

In addition, in the period covered by the financial statements incorporated herein by reference, there has not been, nor is there 
currently proposed, any material transaction or series of similar material transactions to which we were or are a party in which any 
of the members of our board of directors or senior management, holders of more than 10% of any class of our voting securities, 
or any member of the immediate family of any of the foregoing persons, had or will have a direct or indirect material interest, 
other than the compensation and shareholding arrangements we describe in paragraph 5.3.1 “Principal Shareholders” and the 
transactions we describe below. 

Agreements with Our Executive Management
We have entered into a management agreement with Tim Van Hauwermeiren as our chief executive officer. The chief executive 
officer is our sole executive director. The key terms of his agreement are as follows:

Base salary

Cash bonus

Pension contributions(2) 

Duration

TIM VAN HAUWERMEIREN

525,000

Maximum 55% of base salary based on previously determined bonus 
targets established by the non-executive directors(1) 

21,532

Indefinite

We may terminate Mr. Van Hauwermeiren’s services upon 18 months’ notice, or payment of 18 months’ pro-rated base salary in lieu 
of notice. Mr. Van Hauwermeiren would be entitled to the same payment in lieu of notice in the event he terminates his services 
with us in circumstances in which it cannot reasonably be expected for him to continue providing services to us (and after our 
failure to remedy such conditions after being provided at least 14 days’ notice). Mr. Van Hauwermeiren would also be entitled to 
payment in lieu of notice in the event he terminated his services with us in certain cases of our failure to comply with obligations 
under applicable law or his agreement (and after our failure to remedy such non-compliance, if non-deliberate, after being provided 
at least 14 days’ notice). In these cases, there will be a full acceleration of the vesting of any outstanding stock options held by Mr. 
Van Hauwermeiren. There will be no notice period or payment in lieu of notice in certain cases of Mr. Van Hauwermeiren’s failure 
to comply with obligations under applicable law or his agreement. Mr. Van Hauwermeiren may be dismissed immediately as an 
executive director. 

(1)  We have an established practice to provide the variable pay partially in the form of OTC options. For those beneficiaries that opt to receive their 

bonus through over the counter (OTC) options rather than through a payment in cash. As a result, whereas the basis for calculating the cash bonus 
is a maximum of 55% of base salary, in practice this may be paid in OTC options, representing a higher percentage of the annual base salary (in 
2019: 62.15%), which provides a benefit to us as well as the employee.

(2)  Amounts shown represent pension contributions paid during the year-ended December 31, 2019.

Indemnification Agreements
In connection with our initial U.S. public offering, we entered into indemnification agreements with each of our non-executive 
directors and each member of our executive management. Insofar as indemnification for liabilities arising under the Securities 
Act may be permitted to non-executive directors, 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.

FairJourney was founded in 2012 and, as compensation for their support with the formation of FairJourney, our chief executive 
officer and executive director Tim Van Hauwermeiren acquired shares representing 5% of the equity securities of FairJourney, and 
our chief scientific officer, Hans de Haard, acquired shares representing 20% of the equity securities of FairJourney. In July 2012, we 
entered into a license and exclusive option agreement with FairJourney, pursuant to which we granted FairJourney a worldwide, 
non exclusive license to our SIMPLE AntibodyTM Platform to develop, manufacture and commercialize SIMPLE Antibodies to certain 
targets selected by FairJourney. Under the terms of the agreement, once FairJourney has advanced a product candidate discovered 
under the agreement to near proof of concept stage, we have the option to acquire patent rights generated by FairJourney specific 
to such product candidate along with a non exclusive license to additional FairJourney intellectual property useful for further 
development, manufacture, or commercialization of the product candidate. Upon exercising this option, we must pay FairJourney 
an option fee equal to two times the expenses incurred by FairJourney for advancing such product candidate through the option 
exercise date, and we are required to pay a specified royalty in the mid single digits on any sub licensing revenue received by us 
for such product candidate. Alternatively, if we elect not to exercise the option, FairJourney is required to pay us a specified royalty 
in the mid single digits on any sub licensing revenue received by FairJourney for such product candidate. In connection with the 
agreement, we acquired shares of FairJourney representing 15% of the fully diluted equity securities of FairJourney at the time of 
issuance. In December 2017, the Company and executive director Tim Van Hauwermeiren sold their respective shareholdings in 
FairJourney Biologics LDA. In January 2020, the stake held by Prof.. Hans de Haard in FairJourney was sold. This means that at the 
date of this Registration Document, FairJourney LDA no longer qualifies as related party.

Collective bargaining agreements, or CBAs, can be entered into in Belgium at the national, industry, or company levels. These CBAs 
are binding on both employers and employees. We have no trade union representation or CBAs at the company level, but we are 
subject to the national and industry level CBAs that relate to the chemical industry. The CBAs currently applicable to us relate to 
employment conditions such as wages, working time, job security, innovation and supplementary pensions. We have not had, and do 
not anticipate having, disputes on any of these subjects. CBAs may, however, change the employment conditions of our employees 
in the future and hence adversely affect our employment relationships.

6.8.  Certain relevant provisions of applicable law and our articles of 

association

6.8.1.  ISSUE OF SHARES

The Articles of Association provide that shares may be issued or rights to subscribe for our shares may be granted pursuant to a 
resolution of the shareholders at the General Meeting, or alternatively, by our board of directors if so designated by the shareholders 
at the General Meeting. A resolution of the shareholders at the General Meeting to issue shares, to grant rights to subscribe for 
shares or to designate our board of directors as the corporate body of the company authorized to do so can only take place at the 
proposal of our board of directors with the consent of the majority of the non-executive directors. Shares may be issued or rights 
to subscribe for shares may be granted by resolution of our board of directors, if and insofar as our board of directors is designated 
to do so by the shareholders at the General Meeting. Designation by resolution of the shareholders at the General Meeting cannot 
be withdrawn unless determined otherwise at the time of designation. The scope and duration of our board of directors’ authority 
to issue shares or grant rights to subscribe for shares (such as granting stock options or issuing convertible bonds) is determined 
by a resolution of the shareholders at the General Meeting and relates, at the most, to all unissued shares in the company’s autho-
rized capital at the relevant time. The duration of this authority may not exceed a period of five years. Designation of our board 
of directors as the body authorized to issue shares or grant rights to subscribe for shares may be extended by a resolution of the 
shareholders at the General Meeting for a period not exceeding five years in each case. The number of shares that may be issued 
is determined at the time of designation. 

(1)  until March 16, 2020.

184  |  Employees

No shareholders’ resolution or board of directors resolution is required to issue shares pursuant to the exercise of a previously 
granted right to subscribe for shares. A resolution of our board of directors to issue shares and to grant rights to subscribe for shares 
can only be taken with the consent of the majority of the non-executive directors. 

On May 7, 2019, the shareholders at the General Meeting designated our board of directors as the corporate body competent to 
issue shares under the Option Plan and to limit or exclude pre-emptive rights of shareholders for such shares and option rights to 
subscribe for shares with the prior consent of the majority of the non-executive directors for a period of 18 months. On May 7, 2019, 
the shareholders at the General Meeting designated our board of directors as the corporate body competent to issue additional 
shares and grant rights to subscribe for shares and to limit or exclude pre-emptive rights of shareholders for such shares with the 
prior consent of the majority of the non-executive directors for a period of 18 months. In its resolution, the shareholders at the 
General Meeting restricted the competency of our board of directors under this second authorization as regards the issue of shares 
and the grant of rights to subscribe for shares to a maximum of 20% of our total issued and outstanding share capital as at the day 
of that meeting. The purpose of this authorization is to allow the board of directors the general flexibility to issue additional shares 
as and when the need may arise or an opportunity would present itself, including to issue shares and grant rights to subscribe for 
shares and to limit or exclude pre-emptive rights of shareholders for such shares for the purpose of the admission to listing and 
trading of securities in our capital on Nasdaq and/or Euronext. While there is no current intention to benefit any specific person 
with this authorization to restrict the pre-emptive rights of the existing shareholders, when using this authorization the board will 
be able to restrict the pre-emptive rights in whole or in part, including for the benefit of specific persons. The board’s ability to 
restrict the pre-emptive rights in whole or in part could be used by the board as a potential anti-takeover measure, although there 
is currently no likely scenario in which we expect that such ability would be used as an anti-takeover measure.

6.8.2.  PUBL IC OFFER

In accordance with Directive 2004/25/EC, each European Union member state should ensure the protection of minority shareholders 
by obliging any person that acquires control of a company to make an offer to all the holders of that company’s voting securities 
for all their holdings at an equitable price. The Directive 2004/25/EC applies to all companies governed by the laws of a European 
Union member state of which all or some voting securities are admitted to trading on a regulated market in one or more European 
Union member states. The laws of the European Union member state in which a company has its registered office will determine 
the percentage of voting rights that is regarded as conferring control over that company. In accordance with Section 5:70 of the 
DFSA, any person—whether acting alone or in concert with others— who, directly or indirectly, acquires a controlling interest in a 
company will be obliged to launch a mandatory public offer for all our outstanding shares. A controlling interest is deemed to exist if 
a (legal) person is able to exercise, alone or acting in concert, at least 30% of the voting rights in the General Meeting. An exception 
is made for, amongst others, shareholders who—whether alone or acting in concert with others—(i) had an interest of at least 30% 
of our voting rights before our shares were first admitted to trading on Euronext Brussels and who still have such an interest after 
such first admittance to trading, and (ii) reduce their holding to below 30% of the voting rights within 30 days of the acquisition 
of the controlling interest provided that (a) the reduction of their holding was not effected by a transfer of shares to an exempted 
party and (b) during such period such shareholders or group of shareholders did not exercise their voting rights. The rules under 
the DFSA regarding mandatory public offers apply to us because the Company has its statutory seat in the Netherlands. However, as 
the shares are not admitted to trading on a regulated market in the Netherlands but are admitted to trading on Euronext Brussels 
and the ADSs are admitted to trading on The Nasdaq Global Select Market, the Dutch Decree on public offers (Besluit openbare 
biedingen Wft) will only apply in relation to matters relating to information to be provided to trade unions and employees and 
company law matters, including the convocation of a General Meeting in the event of a public offer and a position statement by our 
board of directors. In case of a mandatory public offer, the provisions regarding the offered consideration and the bid procedure 
will be governed by Belgian law pursuant to article 4§1, 3° of the Belgian law dated April 1, 2007 on public takeover bids, or the 
Takeover Law. Pursuant to article 53 of the Belgian Royal Decree of April 27, 2007 on public takeover bids, or the Takeover Royal 
Decree, a mandatory public offer on our shares must be launched at a price equal to the higher of (i) the highest price paid by the 
offeror or persons acting in concert with it for the acquisition of shares during the last 12 months and (ii) the weighted average 
trading prices during the last 30 days before the obligation to launch a mandatory public offer was triggered. The price can be in cash 
or in securities. However, if the securities that are offered as consideration are not liquid securities that are traded on a regulated 
market or if the offeror or persons acting in concert with it have acquired shares for cash in the last 12 months, a cash alternative 
has to be offered. Various protective measures are possible and permissible within the boundaries set by Dutch law and Dutch case 
law. We have not implemented specific measures with the aim of deterring takeover attempts. However, we have adopted several 

Certain relevant provisions of applicable law and our articles of association    |  185 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCEprovisions that may have the effect of making a takeover of our Company more difficult or less attractive, including requirements 
that certain matters, including an amendment of our Articles of Association, may only be brought to our shareholders for a vote 
upon a proposal by our board of directors. No takeover bid has been instigated by third parties in respect of our equity during the 
previous financial year and the current financial year.

6.8.3.  AMENDMENT OF ART ICLES OF ASS OC I ATI O N

The shareholders at the General Meeting may resolve to amend the Articles of Association, at the proposal of our board of direc-
tors, with the consent of the majority of the non-executive directors. A resolution by the shareholders at the General Meeting to 
amend the Articles of Association requires a simple majority of the votes cast in a meeting in which at least half of our issued and 
outstanding capital is present or represented, or at least two-thirds of the votes cast, if less than half of our issued and outstanding 
capital is present or represented at that meeting. 

Changing the rights of any of the shareholders will require the Articles of Association to be amended.

6.8.4.  SQUEEZE OUT PROCEDURES

Pursuant to Section 92a, Book 2, Dutch Civil Code, a shareholder who for his own account holds at least 95% of our issued share 
capital may initiate proceedings against our minority shareholders jointly for the transfer of their shares to the claimant. The 
proceedings are held before the Dutch Enterprise Chamber of the Amsterdam Court of Appeal (Ondernemingskamer van het 
Gerechtshof te Amsterdam), or the Enterprise Chamber, and can be instituted by means of a writ of summons served upon each 
of the minority shareholders in accordance with the provisions of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke 
Rechtsvordering). The Enterprise Chamber may grant the claim for squeeze out in relation to all minority shareholders and will 
determine the price to be paid for the shares, if necessary after appointment of one or three experts who will offer an opinion to 
the Enterprise Chamber on the value to be paid for the shares of the minority shareholders. Once the order to transfer becomes 
final before the Enterprise Chamber, the person acquiring the shares will give written notice of the date and place of payment and 
the price to the holders of the shares to be acquired whose addresses are known to him. Unless the addresses of all of them are 
known to the acquiring person, such person is required to publish the same in a daily newspaper with a national circulation. In 
addition, pursuant to Section 359c, Book 2 of the Dutch Civil Code, following a public offer, a holder of at least 95% of our issued 
share capital and voting rights has the right to require the minority shareholders to sell their shares to it. Any such request must 
be filed with the Enterprise Chamber within three months after the end of the acceptance period of the public offer. Conversely, 
pursuant to article 2:359d of the Dutch Civil Code each minority shareholder has the right to require the holder of at least 95% of 
our issued share capital and voting rights to purchase its shares in such case. The minority shareholder must file such claim with 
the Enterprise Chamber within three months after the end of the acceptance period of the public offer.

6.8.5.  MARKET ABUSE RULES

As of July 3, 2016, setting aside previously applicable national legislation in the European Union member states, Regulation (EU) 
No 596/2014 of the European Parliament and of the Council of April 16, 2014 on market abuse (market abuse regulation) and 
repealing Directive 2003/6/EC of the European Parliament and of the Council and Commission Directives 2003/124/EC, 2003/125/
EC and 2004/72/EC, and the rules and regulations promulgated pursuant thereto, or MAR, provides for specific rules intended to 
prevent market abuse, such as prohibitions on insider trading, divulging inside information and tipping and market manipulation. 
The Company, the members of our board of directors and other insiders and persons performing or conducting transactions in the 
Company’s financial instruments, as applicable, will be subject to the insider trading prohibition, the prohibition on divulging inside 
information and tipping and the prohibition on market manipulation. In certain circumstances, the Company’s investors may also 
be subject to market abuse rules. 

Inside information is any information of a precise nature relating (directly or indirectly) to us, or to our shares or other financial 
instruments, which information has not been made public and which, if it were made public, would be likely to have a significant 
effect on the price of the shares or the other financial instruments or on the price of related derivative financial instruments. 

186  |  Certain relevant provisions of applicable law and our articles of association

Pursuant to the MAR, a person is prohibited to possess inside information and use that information by acquiring or disposing of, 
for its own account or for the account of a third party, directly or indirectly, our shares and other financial instruments to which 
that information relates (which is considered to be insider trading). The use of inside information by cancelling or amending an 
order concerning our shares or other financial instruments to which the information relates where the order was placed before 
the person concerned possessed the inside information, is also prohibited. In addition, a person is also prohibited to recommend 
another person to engage in insider trading, or induce another person to engage in insider trading, which arises where the person 
possesses inside information and (a) recommends, on the basis of that information, that another person acquires or disposes of 
our shares or other financial instruments to which that information relates, or induces that person to make such an acquisition or 
disposal or (b) recommends, on the basis of that information, that another person cancels or amends an order concerning our shares 
or other financial instruments to which that information relates, or induces that person to make such a cancellation or amendment. 

The Company is under an obligation to make any inside information immediately public by means of a press release. However, the 
Company may, in its own discretion, delay the publication of inside information if it can ensure the confidentiality of the information. 
Such deferral is only permitted if the publication thereof could damage the Company’s legitimate interests and if the deferral does 
not risk misleading the market. If the Company wishes to use this deferral right it needs to inform the Belgian Financial Services and 
Markets Authority thereof after the information is disclosed to the public and provide a written explanation of how the conditions 
for deferral were met. 

The Company is subject to Dutch law, Belgian law and MAR regarding the publication of inside information. Directors, other persons 
discharging managerial responsibilities and persons closely associated with them are covered by the MAR notification obligations. 
Directors and other persons discharging managerial responsibilities as well as persons closely associated with them, must notify 
the AFM of every transaction conducted on their own account relating to the shares or debt instruments of the Company, or to 
derivatives or other financial instruments linked to those shares or debt instruments. Notification must be made within three 
working days after the date of the transaction. Under MAR, no notification of a transaction needs to be made until transactions in 
a calendar year by that director, persons discharging managerial responsibilities or persons closely associated with them exceed a 
threshold of €5,000 (without netting). Once the threshold has been reached, all transactions will need to be notified, regardless of 
amount and wherever concluded. Non-compliance with these reporting obligations could lead to criminal penalties, administrative 
fines and cease-and-desist orders (and the publication thereof), imprisonment or other sanctions. 

6.8.6.  TRANSPAREN CY DI RECTIVE

We are a European public company with limited liability (Societas Europaea or SE) incorporated and existing under the laws of the 
Netherlands. The Netherlands is our home European Union member state (lidstaat van herkomst) for the purposes of Directive 
2004/109/EC of the European Parliament and of the Council of December 15, 2004 on the harmonization of transparency require-
ments in relation to information about issuers whose securities are admitted to trading on a regulated market and amending 
Directive 2001/34/EC and the rules and regulations promulgated pursuant thereto, as amended by various directives including 
2013/50/EU, or the Transparency Directive, as a consequence of which we will be subject to the DFSA in respect of certain ongoing 
transparency and disclosure obligations. In addition, as long as our shares are listed on Euronext Brussels and the ADSs on The 
Nasdaq Global Select Market, we are required to disclose any regulated information which has been disclosed pursuant to the DFSA 
as well in accordance with the Belgian Act of May 2, 2007, the Belgian Royal Decree of November 14, 2007 and Nasdaq listing rules. 
We must publish our annual accounts within four months after the end of each financial year and our half-yearly figures within two 
months after the end of the first six months of each financial year. Within five calendar days after adoption of our annual accounts, 
we must file our adopted annual accounts with the AFM. Pursuant to the DFSA, we will be required, among other things, to make 
public without delay any change in the rights attaching to our shares or any rights to subscribe our shares.

6.8.7.  DUTCH FINANC IAL REPORTING SU P ERV I S I O N ACT

Pursuant to the Dutch Financial Reporting Supervision Act (Wet toezicht financiële verslaggeving), or the DFRSA, the AFM supervises 
the application of financial reporting standards by companies whose official seat is in the Netherlands and whose securities are 
listed on a regulated Dutch or foreign stock exchange. Pursuant to the DFRSA, the AFM has an independent right to (i) request an 
explanation from us regarding our application of the applicable financial reporting standards if, based on publicly known facts or 
circumstances, it has reason to doubt that our financial reporting meets such standards and (ii) recommend to us that we make 

Certain relevant provisions of applicable law and our articles of association    |  187 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCORPORATE GOVERNANCEavailable further explanations and files these with the AFM. If we do not comply with such a request or recommendation, the 
AFM may request that the Enterprise Chamber orders us to (a) provide an explanation of the way we have applied the applicable 
financial reporting standards to our financial reports or (b) prepare our financial reports in accordance with the Enterprise Chamber’s 
instructions.

6.8.8.  NET SHORT POSI TION

Pursuant to European Union regulation No 236/2012, each person holding a net short position attaining 0.2% of our issued share 
capital of must report it to the AFM. Each subsequent increase of this position by 0.1% above 0.2% will also have to be reported. 
Each net short position equal to 0.5% of our issued share capital and any subsequent increase of that position by 0.1% will be made 
public via the AFM short selling register. To calculate whether a natural person or legal person has a net short position, their short 
positions and long positions must be set off. A short transaction in a share can only be contracted if a reasonable case can be made 
that the shares sold can actually be delivered, which requires confirmation of a third party that the shares have been located. The 
notification will be made no later than 15:30 CET on the following trading day.

6.8.9.  GROSS SHORT POSITI ON

Furthermore, each person holding a gross short position in relation to our issued share capital that reaches, exceeds or falls below 
one of the following thresholds: 3%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75% and 95%, must immediately give written 
notice to the AFM. 

If a person’s gross short position reaches, exceeds or falls below one of the abovementioned thresholds as a result of a change in 
our issued share capital, such person is required to make a notification not later than on the fourth trading day after the AFM has 
published our notification in the public register of the AFM. 

The AFM keeps a public register of the short selling notifications. Shareholders are advised to consult with their own legal advisors 
to determine whether any of the above short selling notification obligations apply to them.

Accordingly, any discrepancies in any tables between the totals and the sums of amounts listed are due to rounding.

7.6.3.  EXCHANGE RATE INFORMATION

Fluctuations in the exchange rate between the euro and the U.S. dollar will affect the U.S. dollar amounts received by owners of

7.7.  Market and Industry Information

Market information (including market share, market position and industry data for our operating activities and those of our subsid-
iaries) or other statements presented in this Registration Document regarding our position relative to our competitors largely reflect 
the best estimates of our management. These estimates are based upon information obtained from customers, trade or business 
organizations and associations, other contacts within the industries in which we operate and, in some cases, upon published 
statistical data or information from independent third parties. 

This Registration Document contains statistics, data and other information relating to markets, market sizes, market shares, market 
positions and other industry data pertaining to our business and markets. 

194  |  Market and Industry Information

Certain other statistical or market-related data has been estimated by management based on reliable third-party sources, where 
possible, including those referred to above or based on data generated in-house by us. Although management believes its estimates 
regarding markets, market sizes, market shares, market positions and other industry data to be reasonable, these estimates have 
not been verified by any independent sources (except where explicitly cited to such sources), and we cannot assure shareholders 
as to the accuracy of these estimates or that a third party using different methods to assemble, analyze or compute market data 
would obtain the same results. Management’s estimates are subject to risks and uncertainties and are subject to change based 
on various factors. We do not intend, and do not assume any obligation, to update the industry or market data set forth herein. 

Industry publications or reports generally state that the information they contain has been obtained from sources believed to be 
reliable, but the accuracy and completeness of such information is not guaranteed. We have not independently verified and cannot 
give any assurance as to the accuracy of market data contained in this Registration Document that were extracted or derived from 
these industry publications or reports. Market data and statistics are inherently predictive and subject to uncertainty and not 
necessarily reflective of actual market conditions. Such statistics are based on market research, which itself is based on sampling 
and subjective judgments by both the researchers and the respondents, including judgments about what types of products and 
transactions should be included in the relevant market. 

As a result, shareholders/investors should be aware that statistics, data, statements and other information relating to markets, 
market sizes, market shares, market positions and other industry data in this Registration Document and estimates and assumptions 
based on that information are necessarily subject to a high degree of uncertainty and risk due to the limitations described above 
and to a variety of other factors, including those described in chapter 1 “Risk factors” and elsewhere in this Registration Document.

Management confirmations
With due regard to best practice principle 1.4.3 of the Dutch Corporate Governance Code, we confirm that:

I. 

II. 

This Registration Document provides sufficient insights into any failings in the effectiveness of the internal risk management 
and control systems, as is further substantiated in chapter 1 “Risk Factors” and section 6.5 “Risk appetite and control”;
The risk- and control systems described herein, particularly in section 6.5.6 “Financial risks and controls” provide reasonable 
assurance that the financial reporting does not contain any material inaccuracies;

IV. 

III.  We confirm that we expect that our existing cash and cash equivalents and current financial assets will enable us to fund our 
operating expenses and capital expenditure requirements through at least the next 12 months. On the basis of the current 
state of affairs, it is justified that the financial reporting is prepared on a going concern basis; and
This report, particularly chapter 1 “Risk Factors” states those material risks and uncertainties that are relevant to the expecta-
tion of our continuity for the period of twelve months after the preparation of this Registration Document. The aforementioned 
statement does not in any way limit the relevance or applicability of the Risk Factors set out in this Registration Document 
to the aforementioned period of 12 months.

Significant accounting policies

The significant Company’s accounting policies are summarized below.

2.1. 

STATEMENT OF COMPLIANCE AN D BAS I S O F PR E PAR ATI O N

The consolidated financial statements are prepared in accordance with the International Financial Reporting Standards (IFRS), as 
adopted by the EU. The consolidated financial statements provide a general overview of the Company’s activities and the results 
achieved. They present fairly the entity’s financial position, its financial performance and cash flows, on a going concern basis. The 
accounting policies described in Note 2 to our consolidated financial statements have been applied in preparing the consolidated 
financial statements as of and for the year ended December 31, 2019 and for the comparative information as of and for the years 
ended December 31, 2018 and 2017.

The preparation of consolidated financial statements in conformity with IFRS, issued by the IASB, requires the use of certain critical 
accounting estimates. It also requires management to exercise its judgment in the process of applying the Company’s accounting 
policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant 
to the consolidated financial statements are disclosed in Note 3.

The significant accounting policies applied in the preparation of the above consolidated financial statements are set out below. All 
amounts are presented in thousands of euro, unless otherwise indicated, rounded to the nearest € ‘000.

The consolidated financial statements have been approved for issue by the Company’s Board of Directors (the Board) on March 
31, 2020.

2.2. 

BA S I S OF CONSOLIDATION

The consolidated financial statements include the financial statements of the Company and entities controlled by the Company (its 
subsidiaries). Control is achieved when the Company:

•  has power over the investee;
• 
•  has the ability to use its power to affect its returns.

is exposed, or has rights, to variable returns from its involvement with the investee; and

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.

Notes to the Consolidated Financial Statements    |  213 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSConsolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses 
control of the subsidiary. Income and expenses of subsidiaries acquired or disposed of during the year are included in the consol-
idated statement of profit and loss and other comprehensive income from the effective date of acquisition and up to the effective 
date of disposal, as appropriate.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with 
those used by other members of the Group.

All inter-company transactions and unrealized gains on transactions between group companies are eliminated. Unrealised losses 
are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of 
subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.3. 

FOREIGN CURRENCY TRAN SACT I O N S

Functional and presentation currency
The consolidated financial statements are presented in euro (€), which is the Company’s presentation currency and the Company’s 
functional currency.

Transactions and balances
Transactions in foreign currencies are translated at the exchange rate ruling at the date of the transaction. Monetary assets and liabil-
ities denominated in foreign currencies are translated at the exchange rate ruling at the reporting date. Foreign exchange differences 
arising on translation are recognized in the statement of profit and loss and other comprehensive income. Non monetary assets 
and liabilities denominated in foreign currencies are translated at the foreign exchange rate ruling at the date of the transaction.

Financial statements of foreign entities
For foreign entities using a different functional currency than the euro:

•  assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that statement of financial 

• 

position.
income and expenses for each statement presenting profit or loss and other comprehensive income are translated at average 
exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the 
transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions).

•  all resulting exchange differences are recognised in other comprehensive income.

2.4. 

INTANGIBLE ASS ETS

2.4.1. 

Internally generated intangible assets

Expenditure on research activities is recognized as an expense in the period in which it is incurred.

An internally generated intangible asset arising from development (or from the development phase of an internal project) is 
recognized if, and only if, all of the following have been demonstrated:

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;

• 
• 
• 
•  how the 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
the ability to measure reliably the expenditure attributable to the intangible asset during its development.

• 

214  |  Notes to the Consolidated Financial Statements

The amount initially recognized for internally generated intangible assets is the sum of the expenditure incurred from the date 
when the intangible asset first meets the recognition criteria listed above. Where no internally generated intangible asset can be 
recognized, development expenditures are recognized in the statement of profit and loss and other comprehensive income in the 
period in which they are incurred.

Due to uncertainties inherent to the development and registration with the relevant healthcare authorities of its products, the 
Company estimates that the conditions for capitalization are not met until the regulatory procedures required by such healthcare 
authorities have been finalized. The Company currently does not own products that have been approved by the relevant healthcare 
authorities.

Subsequent to initial recognition, internally generated intangible assets are reported at cost less accumulated amortization and 
accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

2.4.2. 

Intangible assets acquired separately

Intangible assets with finite useful lives that are acquired separately are carried at cost less accumulated amortization and accu-
mulated impairment losses. Amortization is recognized on a straight line basis over their estimated useful lives which are disclosed 
in note 4. The estimated useful life and amortization method are reviewed at the end of each reporting period, with the effect of 
any changes in estimate being accounted for on a prospective basis. Intangible assets with indefinite useful lives that are acquired 
separately are carried at cost less accumulated impairment losses.

Payments for acquired in-process research and development projects obtained through in-licensing arrangements, business combi-
nations and separate asset purchases are capitalized as intangible assets provided that they are separately identifiable, controlled 
by the Company and expected to provide future economic benefits. As the probability criterion in IAS 38 is always considered to 
be satisfied for separately acquired research and development assets and the amount of the payments is determinable, upfront 
and milestone payments to third parties for pharmaceutical products or compounds for which regulatory marketing approval has 
not yet been obtained are recognized as intangible assets, and amortized on a straight line basis over their useful lives beginning 
when the underlying drug candidate is approved and launched commercially, or expensed immediately if development of the drug 
candidate is abandoned.

2.4.3.  Derecognition of intangible assets

An intangible asset is derecognized either on disposal or when no future economic benefits are expected from its use. 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.

2.5. 

PROPERTY, PLANT AN D EQUIPME NT

Items of property, plant and equipment held for use in the production or supply of goods or services, or for administrative purposes, 
are stated in the statement of financial position at their cost, less accumulated depreciation and accumulated impairment losses.

The cost comprises the initial purchase price plus other direct purchase costs (such as non refundable tax and transport).

Depreciation is recognized as from acquisition date onwards (unless asset is not ready for use) so as to write off the cost or valuation 
of assets (other than freehold land and properties under construction) less their residual values over their useful lives, using the 
straight line method. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting 
period, with the effect of any changes in estimate accounted for on a prospective basis.

Unless revised due to specific changes in the estimated useful life, annual depreciation rates are as follows:

•  Office and lab equipment: 3–5 years
• 

IT equipment: 3 years

Notes to the Consolidated Financial Statements    |  215 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSAn item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to 
arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and 
equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in 
profit or loss.

2.6. 

LEASES

As explained in note 2.22 below, the Company has changed its accounting policy for leases where the Company is the lessee. 

Until December 31, 2018, leases of property, plant and equipment where the Company, as lessee, had substantially all the risks and 
rewards of ownership were classified as finance leases. Finance leases were capitalised at the lease’s inception at the fair value of 
the leased property or, if lower, the present value of the minimum lease payments. The corresponding rental obligations, net of 
finance charges, were included in other short-term and long-term payables. Each lease payment was allocated between the liability 
and finance cost. The finance cost was charged to the profit or loss over the lease period so as to produce a constant periodic rate of 
interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases 
was depreciated over the asset’s useful life or over the shorter of the asset’s useful life and the lease term if there is no reasonable 
certainty that the Company will obtain ownership at the end of the lease term.

Leases in which a significant portion of the risks and rewards of ownership were not transferred to the Company as lessee were 
classified as operating leases. Operating lease payments were recognized as an expense on a straight line basis over the lease term, 
except where another systematic basis was more representative of the time pattern in which economic benefits from the leased 
asset are consumed.

As from January 1, 2019, the Company assesses whether a contract is or contains a lease, at inception of the contract. The Company 
recognises a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, 
except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these 
leases, the Company recognises the lease payments as an operating expense on a straight-line basis over the term of the lease unless 
another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, 
discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the lessee uses its incremental borrowing 
rate. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the 
effective interest method) and by reducing the carrying amount to reflect the lease payments made. The lease liability is presented 
as a separate line in the consolidated statement of financial position.

The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before 
the commencement day, less any lease incentives received and any initial direct costs. They are subsequently measured at cost 
less accumulated depreciation and impairment losses. Right-of-use assets are depreciated over the shorter period of lease term 
and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset 
reflects that the Company expects

to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The right-
of-use assets are presented in the statement of financial position under the caption “Property, plant and equipment”.

2.7. 

I MPA I RMENT OF ASS ETS

At the end of each reporting period, the Company reviews the carrying amounts of its tangible and intangible assets to determine 
whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable 
amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where 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.

216  |  Notes to the Consolidated Financial Statements

Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, 
and whenever there is an indication that the asset may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash 
flows are discounted to their present value using a pre tax discount rate that reflects current market assessments of the time value 
of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

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. An impairment loss is recognized immediately in profit 
or loss.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash generating unit) is increased to the 
revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that 
would have been determined had no impairment loss been recognized for the asset (or cash generating unit) in prior years. A 
reversal of an impairment loss is recognized immediately in profit or loss.

2.8. 

FINA NCIAL ASSETS: I NVESTME N TS

I. 

Classification

The Company classifies its financial assets in the following measurement categories: those to be measured subsequently at fair value 
through profit or loss (FVTPL) and those to be measured at amortized cost. The classification depends on the Company’s business 
model for managing the financial assets and the contractual terms of the cash flows.

Regular purchases and sales of financial assets are recognized on the trade date – the date on which the Company commits to 
purchase or sell the asset. Financial assets are derecognized when the rights to receive cash flows from the investments have expired 
or have been transferred and the Company has transferred substantially all risks and rewards of ownership. For assets measured 
at fair value, gains and losses will be recorded in profit or loss.

II.  Measurement

At initial recognition, the Company measures a financial asset at its fair value plus, in case of a financial asset not at FVTPL, trans-
action costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at 
FVTPL are expensed in profit or loss. 

The Company subsequently measures all equity investments at fair value. Dividends from such investments continue to be recog-
nized in profit or loss as financial income when the Company’s right to receive payments is established. Changes in the fair value 
of financial assets at FVPL are recognized in financial income/expenses in the statement of profit or loss. The fair value of listed 
investments is based on current market prices. If the market for a financial asset is not active (and for unlisted securities), the 
Company establishes fair value by using valuation techniques.

2.9. 

TRA D E AND OTHER RECEIVABLE S

Trade receivables are recognised initially at the amount of consideration that is unconditional. The Company holds the trade 
receivables with the objective to collect the contractual cash flows and therefore measures them subsequently at amortised cost 
using the effective interest method. Unless the impact of discounting is material, the nominal value is recognized.

Trade receivables are recognized initially at their transaction price and are subsequently measured at amortized cost using the 
effective interest rate method, less provision for expected credit losses. For determining the expected credit losses, the Company 
applies the simplified approach permitted by IFRS 9, which requires lifetime losses to be recognized from initial recognition of the 
receivables.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTS2.10.  RESEARCH AN D DEVELOPMENT I N C EN T I V E R ECEI VAB LES

Since the Company carries out extensive research and development activities, it benefits from a research and development incentive 
tax scheme in Belgium under which the research and development incentives can be refunded after five years if not offset against 
future income tax expense. These research and development incentives generally aim to partly reimburse expenditures incurred in 
our research and development efforts and are credited to the statement of profit or loss under the line “Other operating income” 
when the relevant expenditure has been incurred and there is a reasonable assurance that the research and development incentives 
are receivable.

2.11.  CASH AND CASH EQUIVALENTS

Cash and cash equivalents includes cash in hand, deposits held at call with banks and other short term highly liquid investments 
with original maturities of three months or less and with an insignificant risk of changes in value. Bank overdrafts, if any, are shown 
within borrowings in current liabilities on the statement of financial position.

Cash balances that are not available for use by the Company are presented as “restricted cash” in the statement of financial position.

For the purpose of the statements of cash flows, cash and cash equivalents includes cash on hand and deposits held at call or short 
term maturity with banks (three months or less with insignificant risk of changes in value).

2.12.  SHAREHOLDER’S EQUI TY

An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. 
Equity instruments issued by the Company are recognized at the proceeds received, net of direct issue costs.

The Company has never distributed any dividends to its shareholders. As of December 31, 2019, no profits were available for 
distribution.

2.13.  TRADE AND OTHER PAYABLES

Payables after and within one year are measured at amortized cost, i.e., at the net present value of the payable amount. Unless the 
impact of discounting is material, the nominal value is recognized.

2.14.  PROVISIONS

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable 
that the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end 
of the reporting period, taking into account the risks and uncertainties surrounding the obligation. When a provision is measured 
using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (where 
the effect of the time value of money is material).

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receiv-
able is recognized as an asset if it is reasonably certain that reimbursement will be received and the amount of the receivable can 
be measured reliably.

2.15.  RETIREMENT BENEFIT S

The Company offers a post employment, death, disability and healthcare benefit scheme. All employees have access to these 
schemes. The death, disability and healthcare benefits granted to employees of the Company are covered by an external insurance 
company, where premiums are paid annually and charged to the income statement as they were incurred.

218  |  Notes to the Consolidated Financial Statements

The post employment pension plan granted to employees of the Company is a defined contribution plan under Belgian Law.

Under defined contribution plans, the Company pays contributions based on salaries to organizations responsible for paying out 
pensions and social security benefits, in accordance with the laws and agreements applicable in each country.

The Belgian defined contribution pension plans are by law subject to minimum guaranteed rates of return, historically 3.25% 
on employer contributions and 3.75% on employee contributions. These rates have been modified by the law of December 18, 
2015 and effective for contribution paid as from 2016 to a new variable minimum return based on the OLO (‘Obligation Lineaire 
Obligaties’—Belgian Government Bond) rates, with a minimum of 1.75% and a maximum of 3.75%. Hence, from 2016 onwards, 
these plans are accounted for as defined benefit plans (see note 14).

The liability recognized in the balance sheet is the present value of the defined benefit obligation less the fair value of plan assets. 
An independent actuary calculates the defined benefit obligation based on factors such as age, years of service and compensation 
(projected unit credit method). The present value of the defined benefit obligation is determined by discounting the estimated 
future cash outflows using interest rates of high quality corporate bonds denominated in the currency in which the benefits will be 
paid and with terms to maturity that approximate the term when the related liability is due. Current service costs are recognized in 
personnel expenses, which are included in Research and development expenses and in Selling, general and administrative expenses, 
and reflect the increase in the defined benefit obligation resulting from employee service in the current year. Past service costs are 
recognized immediately in personnel expenses. The net interest expense on the defined benefit liability is determined by applying 
the discount rate used to measure the defined benefit obligation at the beginning of the year to the then net defined benefit liability. 
Net interest expense is recognized in personnel expenses. Remeasurement gains and losses of the defined benefit obligation arising 
from experience adjustments and changes in actuarial assumptions are recognized immediately in other comprehensive income.

2.16.  SHORT TERM EMPLOYEE BENE FI TS

Short term employee benefits include payables and accruals for salaries and bonuses to be paid to the employees of the Company. 
They are recognized as expenses for the period in which employees perform the corresponding services.

2.17.  SHARE BASED PAYMENTS

Equity settled share based payments to employees and others providing similar services are measured at the fair value of the equity 
instruments at the grant date. Details regarding the determination of the fair value of equity settled share based transactions are 
set out in note 13.

The fair value determined at the grant date of the equity settled share based payments is expensed on a straight line basis over the 
vesting period, based on the Company’s estimate of equity instruments that will eventually vest, with a corresponding increase in 
equity. At the end of each reporting period, the Company revises its estimate of the number of equity instruments expected to vest. 
The impact of the revision of the original estimates, if any, is recognized in profit or loss such that the cumulative expense reflects 
the revised estimate, with a corresponding adjustment to the equity settled share based payment reserve.

Where the terms of equity settled share based payments are modified, the minimum expense recognized is the expense that would 
have been recognized if the terms had not been modified. An additional expense is recognized for any modification that increases 
the total fair value of the share based payments, or is otherwise beneficial to the employee as measured at the date of modification.

2.18.  DEFERRED REVENUE

Current and non-current deferred revenue relates to cash received from commercial partnerships prior to completion of the earnings 
process. These payments are recognized as revenue over the estimated duration of the Company’s involvement in the research and 
development programs provided for under the terms of the agreements.

IFRS 15 uses the term ‘contract liability’ to describe what might more commonly be known as ‘deferred revenue’, however IFRS 15 
does not prohibit an entity from using alternative descriptions in the statement of financial position. The Company will continue to 
report its contract liabilities under the term ‘deferred revenue.

INCOME TAXES

Income tax expense represents the sum of the tax currently payable and deferred tax.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the statement of 
profit and loss and other comprehensive income because of items of income or expense that are taxable or deductible in other 
years and items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that have 
been enacted or substantively enacted by the end of the reporting period.

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the consolidated 
financial statements and the corresponding tax basis used in the computation of taxable profit (e.g. differences between carrying 
amounts under IFRS and the statutory tax basis). Deferred tax liabilities are generally recognized for all taxable temporary differ-
ences. Deferred tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that 
taxable profits will be available against which those deductible temporary differences can be utilized. Such deferred tax assets and 
liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business 
combination) of other assets and liabilities in a transaction that affects neither the taxable profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no 
longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled 
or the asset realized, based on tax rates (and tax laws) that have been enacted or substantially enacted by the end of the reporting 
period. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in 
which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and deferred tax liabilities are offset if there is a legally enforceable right to offset current tax assets and liabilities 
and if they relate to income taxes imposed by the same authority on the same taxable entity or in different tax entities that intend 
to settle current tax assets and liabilities on a net basis or their tax assets and liabilities will be realized simultaneously.

2.20.  REVENUE AND OTHER OPERATI N G I N CO M E R ECO G N I TI O N

Collaborations
The Company adopted IFRS 15 on January 1, 2018. The Company elected the modified retrospective approach for the transition, 
which foresees that prior period figures remain as reported under the previous standard IAS 18, and the cumulative effect of applying 
IFRS 15 is recognized as an adjustment to the opening balance of equity as at the date of initial application (i.e., the beginning of 
the year 2018). In previous reporting periods, milestone payments were recognized under IAS 18 based upon the achievement of 
the milestone event, whereas under IFRS 15, the milestone payment is linked to a single performance obligation over the estimated 
service period. The revenue recognition of the upfront payments was not impacted by the transition from IAS 18 to IFRS 15.

The cumulative effect of adopting IFRS 15 to the consolidated statement of financial position as of January 1, 2018 was as follows:

The Company generates revenue from collaborations and strategic alliances. The Company applies a five-step model to determine 
when, how and at what amount revenue is to be recognized depending on whether certain criteria are met.

1. 

Identify the contracts

In our current arrangements, the Company is licensing its Intellectual Property, providing research and development services and 
in the future, selling its products to collaborative partner entities. Revenue is generated through these arrangements via upfront 
payments, milestone payments based on development criteria, research and development service fees on an agreed full-time 
equivalent (FTE) basis and future sales based milestones and sales based royalties.

2. 

Identify performance obligations

The Company has assessed that there is one single performance obligation in our material ongoing license and collaboration 
arrangements, being the transfer of a license combined with performance of research and development services.

This is because we consider that the performance obligations cannot be distinct in the context of the contract as the license has 
no stand-alone value without the Company being further involved in the research and development collaboration and that there is 
interdependence between the license and the research and development services to be provided. We estimate that the Company’s 
activities during the collaboration are going to significantly add to Intellectual Property and thereby the value of the programs.

3. 

Determine the transaction price

We have analyzed the transaction prices of our material ongoing license and collaboration arrangements currently composed of 
upfront payments, milestone payments and research and development service fees being delivered. Any variable consideration, 
such as development milestone payments that are promised in exchange for development services or the license of IP, is only 
included in the transaction price as from the moment the achievement of the related milestone event is highly probable (usually 
at the time of achievement of the milestone event). At the end of each subsequent reporting period, the Company re-evaluates 
the probability of achievement of such milestones and any related constraint, and, if necessary, adjusts the estimate of the overall 
transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in 
the period of adjustment. The Company’s collaborators may be required to pay the Company sales-based milestone payments or 
royalties on future sales of commercial products. The Company recognizes revenues related to sales-based milestone and royalty 
payments upon the later to occur of (i) achievement of the collaborator’s underlying sales or (ii) satisfaction of any performance 
obligation(s) related to these sales, in each case assuming the license to the Company’s intellectual property is deemed to be the 
predominant item to which the sales-based milestones and/or royalties relate.

4. 

Allocate the transaction price

In principle, an entity shall allocate the transaction price to each performance obligation identified in the contract on a relative 
stand-alone selling price basis. However, the transaction price of certain of our arrangements is allocated to a single performance 
obligation since the transfer of a license is considered to be combined with performance of research and development services.

Therefore, research and development milestone payments are variable considerations that are entirely allocated to the single 
performance obligation.

5. 

Recognize revenue

Revenue from certain arrangements is recognized over time as the Company satisfies a single performance obligation. Our collab-
orative partner entities simultaneously receive the benefits provided by the Company’s performance as the Company performs.

Notes to the Consolidated Financial Statements    |  221 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSThe Company recognizes upfront payments and milestone payments, allocated to a single performance obligation over the estimated 
service period based on a pattern that reflects the transfer of the services. The revenues recognized reflect the level of service 
each period. In this case, the Company would use an input model that considers estimates of the percentage of total research 
and development service costs that are completed each period compared to the total estimated services costs (percentage of 
completion method).

Research and development service fees are recognized as revenue when costs are incurred and agreed by the parties as the Company 
is acting as a principal in the scope of its stake of the research and development activities of its ongoing license and collaboration 
agreements. 

Grants, research and development incentives and payroll tax rebates
Because it carries out extensive research and development activities, the Company benefits from various grants, research and 
development incentives and payroll tax rebates from certain governmental agencies. These grants, research and development 
incentives and payroll tax rebates generally aim to partly reimburse approved expenditures incurred in research and development 
efforts of the Company and are credited to the statement of profit and loss and other comprehensive income, under other oper-
ating income, when the relevant expenditure has been incurred and there is reasonable assurance that the grants or research and 
development incentives are receivable.

2.21.  EARNINGS PER SHARE

Basic net profit / (loss) per share is computed based on the weighted average number of ordinary shares outstanding during the 
period, excluding treasury shares.

Diluted net profit / (loss) per share is computed based on the weighted average number of ordinary shares outstanding including 
the dilutive effect of options. Options should be treated as dilutive, when and only when their conversion to ordinary shares would 
decrease net profit per share from continuing operations.

2.22.  ADOPTION OF N EW AND REVISE D STAN DAR DS

New accounting policies and disclosures for 2019
The following new standard is mandatory for the first time for the financial year beginning on or after January 1, 2019:

• 

IFRS 16, ‘Leases’ (effective for fiscal years beginning on or after January 1, 2019). This standard replaces the current guidance 
in IAS 17 and is a far reaching change in accounting by lessees in particular. Under IAS 17, lessees were required to make a 
distinction between a finance lease (on balance sheet) and an operating lease (off balance sheet). IFRS 16 requires lessees to 
recognise a lease liability reflecting future lease payments and a ‘right-of-use asset’ for virtually all lease contracts. For lessors, 
the accounting stays almost the same. However, as the IASB has updated the guidance on the definition of a lease (as well as 
the guidance on the combination and separation of contracts), lessors will also be affected by the new standard. Under IFRS 
16, a contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of 
time in exchange for consideration.

The Company has adopted IFRS 16 on January 1, 2019. The Company elected to apply the modified retrospective approach for the 
transition, which foresees that prior period figures remain as reported under the previous standard IAS 17, and the cumulative 
effect of applying IFRS 16 is recognized as an adjustment to the opening balance of equity as of the date of initial application (i.e., 
the beginning of the year 2019). On adoption of IFRS 16, the Company recognized lease liabilities in relation to leases which had 
previously been classified as ‘operating leases’ under IAS 17. These liabilities were measured at the present value of the remaining 
lease payments and discounted using the Company’s incremental borrowing rate as of January 1, 2019. The Company’s weighted 
average incremental borrowing rate applied to these lease liabilities on January 1, 2019 was 1.32%.

222  |  Notes to the Consolidated Financial Statements

The differences between our total operating lease commitments as reported in note 5.7 of our consolidated financial statements 
of December 31, 2018 and the total lease liabilities recognized in our statement of financial position as at January 1, 2019 are 
summarized below:

(IN THOUSANDS OF €)

Operating lease commitments disclosed as at December 31, 2018

(IN THOUSANDS OF €)

The adoption of IFRS 16 does not have a significant impact on the metrics used to measure financial performance. In applying IFRS 
16 for the first time, the Company has used the following practical expedients permitted by the standard:

• 
• 
• 

• 

the use of a single discount rate to a portfolio of leases with reasonably similar characteristics;
reliance on previous assessments on whether leases are onerous;
the accounting for operating leases with a remaining lease term of less than 12 months as at January 1, 2019 as short-term 
leases; and
the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

The Company has also elected not to reassess whether a contract is, or contains, a lease at the date of initial application. Instead, 
for contracts entered into before the transition date, the Company relied on its assessment made applying IAS 17 and IFRIC 4 
Determining whether an Arrangement contains a Lease.

•  Other new standards and amendments to standards that are mandatory for the first time for the financial year beginning on or 

after January 1, 2019 had no material impact on our consolidated financial statements.

New accounting policies and disclosures effective in 2020 or later
The following new standards and amendments to standards have been issued, but are not mandatory for the first time for the 
financial year beginning January 1, 2019 and have been endorsed by the European Union.

•  Amendments to References to the Conceptual Framework in IFRS Standards (effective 1 January 2020). The revised Conceptual 
Framework includes a new chapter on measurement; guidance on reporting financial performance; improved definitions and 
guidance—in particular the definition of a liability; and clarifications in important areas, such as the roles of stewardship, 
prudence and measurement uncertainty in financial reporting.

These amendments are not expected to have any material impact on our consolidated financial statements.

Notes to the Consolidated Financial Statements    |  223 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSThe following new standards and amendments to standards have been issued, but are not mandatory for the first time for the 
financial year beginning January 1, 2019 and have not been endorsed by the European Union.

•  Amendments to IFRS 9, IAS 39 and IFRS 7: Interest Rate Benchmark Reform (effective 1 January 2020). The amendments 
require qualitative and quantitative disclosures to enable users of financial statements to understand how an entity’s hedging 
relationships are affected by the uncertainty arising from interest rate benchmark reform.

These amendments are not expected to have any material impact on our consolidated financial statements.

•  Amendments to the guidance of IFRS 3 Business Combinations, that revises the definition of a business (effective 1 January 
2020). The new guidance provides a framework to evaluate when an input and a substantive process are present (including 
for early stage companies that have not generated outputs). To be a business without outputs, there will now need to be an 
organised workforce. The changes to the definition of a business will likely result in more acquisitions being accounted for as 
asset acquisitions across all industries, particularly real estate, pharmaceutical, and oil and gas. Application of the changes would 
also affect the accounting for disposal transactions.

These amendments are not expected to have any material impact on our consolidated financial statements.

•  Amendments to the definition of material in IAS 1 and IAS 8 (effective 1 January 2020). The amendments clarify the definition 
of material and make IFRSs more consistent. The amendment clarifies that the reference to obscuring information addresses 
situations in which the effect is similar to omitting or misstating that information. It also states that an entity assesses materiality 
in the context of the financial statements as a whole. The amendment also clarifies the meaning of ‘primary users of general 
purpose financial statements’ to whom those financial statements are directed, by defining them as ‘existing and potential 
investors, lenders and other creditors’ that must rely on general purpose financial statements for much of the financial infor-
mation they need. The amendments are not expected to have a significant impact on the preparation of financial statements.
•  Amendments to IAS 1 regarding the classification of liabilities as current or non-current (effective 1 January 2022). The amend-
ments affect only the presentation of liabilities in the statement of financial position, not the amount or timing of recognition of 
any asset, liability, income or expense, or the information that entities disclose about those items. The amendments clarify that 
the classification of liabilities as current or non-current should be based on rights that are in existence at the end of the reporting 
period and align the wording in all affected paragraphs to refer to the “right” to defer settlement by at least twelve months 
and make explicit that only rights in place “at the end of the reporting period” should affect the classification of a liability. They 
also clarify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement 
of a liability and they make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other 
assets or services. The amendments are not expected to have a significant impact on the preparation of financial statements. 

These amendments are not expected to have any material impact on our consolidated financial statements.

• 

IFRS 17 ‘Insurance contracts’ (effective 1 January 2022). This standard replaces IFRS 4, which currently permits a wide variety 
of practices in accounting for insurance contracts. IFRS 17 will fundamentally change the accounting by all entities that issue 
insurance contracts and investment contracts with discretionary participation features.

This standard is not expected to have any material impact on our consolidated financial statements.

2.23.  SEGMENT REPORTING

Segment results include revenue and expenses directly attributable to a segment and the relevant portion of revenue and expenses 
that can be allocated on a reasonable basis to a segment. Segment assets and liabilities comprise those operating assets and liabil-
ities that are directly attributable to the segment or can be allocated to the segment on a reasonable basis. Segment assets and 
liabilities do not include income tax items. The Company manages its activities and operates as one business unit which is reflected 
in its organizational structure and internal reporting. The Company does not distinguish in its internal reporting different segments, 
neither business nor geographical segments. The chief operating decision maker is the Board of Directors.

Critical accounting judgements and key sources of estimation 
uncertainty

In the application of the Company’s accounting policies, which are described above, the Company is required to make judgments, 
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.

The following areas are areas where key assumptions concerning the future, and other key sources of estimation uncertainty at the 
end of the reporting period, have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities 
within the next financial year.

Critical judgements in applying accounting policies

Revenue recognition
The Company recognized revenue of €21.6 million on the basis of costs incurred and deferred revenue of €289.0 million related 
to a global collaboration and license agreement entered into with Cilag GmbH International, an affiliate of Janssen as of and for 
the year ended December 31, 2019. The Company received $500 million as upfront payment for this collaboration and license 
agreement, consisting of $300 million upfront cash payment for the collaboration and license agreement and $200 million as equity 
investment in the Company.

The Company’s collaboration and license agreement has been determined as representing a single distinct performance obligation, 
due to the highly interdependent and interrelated nature of the development, manufacturing, and commercialization of the Licensed 
Compounds and Licensed Products. Fulfillment of the performance obligation occurs throughout the development, manufacturing, 
and commercialization phases of the Licensed Compounds and Licensed Products.

The Company recognizes the consideration received as deferred revenue and subsequently recognizes revenue over the contract 
term (“over time”) based on a research and development cost input model using a percentage of completion method, whereby 
actual research and development costs incurred as part of the Company’s performance obligation is compared to the total expected 
research and development costs needed to satisfy the performance obligation at measurement date.

Research and development cost accruals
The Company recognizes costs of €44.0 million, as specified in note 15 to the financial statements, incurred for clinical trial activities 
and manufacturing of drug products, as research and development expenses based on an evaluation of its vendors’ progress toward 
completion of specific tasks. Payment timing may differ significantly from the period in which the costs are recognized as expense, 
resulting in clinical trial accruals recognized within Trade and other payables in the statement of financial position.

Quantification of the research progress and the translation of the progress to these accruals requires judgment, because the progress 
is not directly observable. In estimating the vendors’ progress toward completion of specific tasks, the Company therefore uses data 
such as patient enrollment, clinical site activations and vendor information of actual costs incurred. This data is obtained through 
reports from or discussions with Company personnel and outside service providers as to the progress or state of completion of trials, 
or the completion of services. Costs are expensed over the service period the services are provided. Costs for services provided that 
have not yet been paid are recognized as accruals. Research and development cost accruals directly impact the revenue recognized, 
given the Company records revenue based on the percentage of completion method.

Intangible assets related to software licenses are amortized over 3 years.

The intangibles assets held by the Company increased substantially as a result of the in-licensing of the ENHANZE® drug delivery 
technology from Halozyme. Under the terms of the agreement, the Company paid an upfront payment of $30 million, exercised the 
option to nominate an additional target (triggering a $10 million development milestone payment) and initiated a Phase 1 clinical 
trial using Halozyme’s proprietary ENHANZE® drug delivery technology (triggering a $5 million development milestone payment). 
In line with its accounting policies, the Company has capitalized this upfront payment upon commencement of the in-license 
agreement. The development milestone payments have been capitalized when the development milestone was triggered.

The Company performed an annual impairment review on the intangible assets not yet available for use. This review did not result 
in the recognition of an impairment charge.

226  |  Notes to the Consolidated Financial Statements

As of December 31, 2019, there are no commitments to acquire additional intangible assets, except as set forth in note 30. No 
intangible assets are pledged as security for liabilities nor are there any intangible assets whose title is restricted.

There are no commitments to acquire property, plant and equipment. Furthermore, no items of property, plant and equipment are 
pledged. See note 23 for information for leases where the Company is a lessee.

(1)  The Company has elected not to reassess whether a contract is, or contains, a lease at the date of initial application. Instead, for contracts entered 
into before the transition date, the Company relied on its assessment made applying IAS 17 and IFRIC 4 Determining whether an Arrangement 
contains a Lease.

Financial assets — non-current

In March 2019, the Company entered into a license agreement with AgomAb Therapeutics NV for the use of HGF-mimetic SIMPLE 
Antibodies™, developed under the Company’s Innovative Access Program. In exchange for granting this license, the Company 
received a profit share in AgomAb Therapeutics NV. The Company assessed the accounting treatment and concluded that the license 
agreement is in scope of IFRS 15 and that any revenue should be recognized at once at the effective date of the agreement. The 
profit share has been designated as a non-current financial asset held at fair value through profit or loss.

In March 2019, AgomAb Therapeutics NV secured €21.0 million in a Series A financing round. The Company used the post-money 
valuation of this Series A financing round and the number of outstanding shares in determining the initial fair value of the profit 
sharing instrument. In October 2019, a subsequent subscription to the Series A financing round increased the number of outstanding 
shares. The Company re-assessed the fair value of the profit sharing instrument, which resulted in a fair value gain on financial 
assets at fair value through profit or loss of €1.1 million.

in relation to a research and development incentive tax scheme in Belgium under which the research and development incentives can 
be refunded after five years if not offset against future income tax expense. The research and development incentives are recorded 
in other operating income (see note 18) in the consolidated statement of profit and loss and other comprehensive income. These 
amounts are expected to be gradually reimbursed in cash as from 2020 onwards.

On December 31, 2019, the Company had a total amount of €0.6 million of restricted cash:

•  A non current part for an amount of €0.6 million mainly relating to a deposit guarantee paid under the lease agreement for the 

laboratory and offices of the Company.

•  The current part of restricted cash related to an escrow account opened under an agreement with a third party involved in the 
collaboration with AbbVie. In 2019, this escrow account has been partially released to the Company and partially to the third 
party, as the work plan of the related collaboration agreement with AbbVie has been almost completed.

The nominal amounts of all trade and other receivables approximate their respective fair values. The VAT receivable relates to VAT 
amounts to be recovered in the first quarter of 2020.

Trade receivables correspond to amounts invoiced to the collaborators or strategic allies of the Company. On December 31, 2019, 
an amount of €0.1 million was due for more than 30 days, but still considered to be collectable. The Company applied the IFRS 9 
simplified approach to measure expected credit losses, which uses a lifetime expected loss allowance for all receivables. To measure 
the expected credit losses, receivables have been grouped based on credit risk characteristics and the days past due. The provision 
for expected credit losses was not significant given that there have been no credit losses over the last three years and the high 
quality nature of our customers. As a result, no bad debt allowance was recorded nor were any trade receivables impaired on 
December 31, 2019 and December 31, 2018.

The Flanders Innovation and Entrepreneurship Agency grant to receive consists of earned income from government grants for which 
no payments have been received but for which the relating expenditures have been incurred. For more information on the Flanders 
Innovation and Entrepreneurship Agency grants to receive, see note 18.

10.  Financial assets — current

On December 31, 2019, the current financial assets amounted to €1,004.5 million compared to €283.5 million on December 31, 
2018. These current financial assets relate to:

•  Financial instruments in the form of money market funds with a recommended investment horizon of 6 months. These funds 
are highly liquid investments and can be readily converted into a known amount of cash, but because of their historical volatility 
these funds cannot be classified as cash and cash equivalents. Values recognized on the balance sheet are the fair values, with 
changes in fair value going through profit and loss.
•  USD term accounts with a maturity of six months.

Please also refer to note 27 for more information on the financial instruments.

New shares issued during 2017
On May 17, 2017, argenx SE offered 5,865,000 of its ordinary shares through an initial public offering in the United States in the

May 19, 2017, the underwriters of the offering exercised their over-allotment option to purchase 879,750 additional ADSs in full. 
As a result, argenx SE received €102.1 million of total gross proceeds from the offering, decreased by €9.6 million of underwriter 
discounts and commissions, and offering expenses, of which €8.9 million has been deducted from equity. The total net cash proceeds 
from this offering amounted to €92.5 million. 

On December 14, 2017, argenx SE offered 4,440,000 of its ordinary shares through a public offering in the United States in the 
form of ADSs at a price to the public of $52.00 per ADS, before underwriting discounts and commissions and offering expenses. On 
December 15, 2017, the underwriters of the offering exercised their over-allotment option to purchase 666,000 additional ADSs in 
full. As a result, argenx SE received €225.6 million of gross proceeds from this offering, decreased by €14.3 million of underwriter 
discounts and commissions, and offering expenses, of which €14.1 million has been deducted from equity. The total net cash 
proceeds from the Offering amounted to €211.3 million. 

For both offerings completed in 2017, the ADSs are evidenced by American Depositary Receipts (ADRs), and each ADS represents 
the right to receive one ordinary share. These ADSs are listed on the NASDAQ Global Select Market under the symbol “ARGX”.

203,412 new shares were also issued in 2017 as a result of the exercise of stock options under the argenx Employee Stock Option 
Plan. 

These issuances of shares resulted in a total of 32,180,641 ordinary shares with a nominal value of €0.1 per share on December 31, 
2017. The extraordinary general meeting of the Company of November 7, 2017 had authorized the board of directors to issue up 
to a maximum of 20% of the then outstanding share capital for a period of 18 months, or up to a capital increase of €537,852.60 
represented by 5,378,526 shares. The board of directors has issued 5,106,000 shares on the occasion of the U.S. public offering in 
December 2017 and as of December 31, 2017, the existing authorization allowed the issuance of up to 272,526 shares.

On September 18, 2018, argenx SE offered 3,475,000 of its ordinary shares through a public offering in the United States in the 
form of ADSs at a price to the public of $86.50 per ADS, before underwriting discounts and commissions and offering expenses. As

and commissions, and offering expenses, of which €14.7 million has been deducted from equity. The total net cash proceeds from 
the offering amounted to €240.9 million.

As a result of the exercise of options under the argenx Employee Stock Option Plan, 319,671 new shares were created in 2018.

and license agreement for cusatuzumab (ARGX-110) with Cilag GmbH International, an affiliate of the Janssen Pharmaceutical 
Companies of Johnson & Johnson. The Company concluded that the share premium that Janssen paid above the closing price on the 
day of entering into the investment agreement (equal to an amount of €24.9 million) was paid because of the existing obligations 
to deliver development services under the terms of the collaboration agreement, and is therefore to be allocated to the single 
performance obligation (see also note 17).

On November 7, 2019, argenx SE offered 4,000,000 of its ordinary shares through a global offering which consisted of (i) a public 
offering of 1,410,057 ADSs in the U.S. and certain other countries outside the European Economic Area (EEA) at a price of $121.00 
per ADS, before underwriting discounts and commissions and offering expenses; and (ii) a concurrent private placement of 2,589,943 
of ordinary shares in the EEA at an offering price of €109.18 per share, before underwriting discounts and commissions and offering 
expenses. On November 8, 2019, the underwriters of the offering exercised their over-allotment option to purchase 600,000 addi-
tional ADSs in full. As a result, argenx SE received €502.2 million of gross proceeds from this offering, decreased by €23.2 million of 
underwriter discounts and commissions, and offering expenses, of which €23.0 million has been deducted from equity. The total 
net cash proceeds from the offering amounted to €479.0 million.

As a result of the exercise of options under the argenx Employee Stock Option Plan, 419,317 new shares were created in 2019.

These issuances of shares resulted in a total of 42,761,528 ordinary shares, with a nominal value of €0.1 per share, on December 31, 
2019. The annual general meeting of the Company on May 9, 2019 had authorized the board of directors to issue up to a maximum 
of 20% of the then outstanding share capital for a period of 18 months, or up to a capital increase of €760,110 represented by 
7,601,101 shares. The board of directors has issued 4,600,000 shares on the occasion of the follow-on global offering in November 
2019, and as of December 31, 2019, the existing authorization allows the issuance of up to 3,001,101 shares.

December 31, 2017. No stock options were expired in the years ended December 31, 2019, 2018 and 2017. 419,317 stock options 
have been exercised in the year ended December 31, 2019 compared to 319,671 in the year ended December 31, 2018 and 203,412

The stock options are granted to employees, consultants or directors of the Company and its subsidiaries. The stock options have 
been granted free of charge. Each employee’s stock option converts into one ordinary share of the Company upon exercise. No

rights. Options may be exercised at any time from the date of vesting to the date of their expiry.

The stock options granted vest, in principle, as follows:

•  1/3rd of the stock options granted will vest on the first anniversary of the granting of the stock options, and
•  1/24th of the remaining 2/3rd of the stock options granted will vest on the last day of each of the 24 months following the 

month of the first anniversary of the granting of the stock options.

On November 25, 2019, at the extraordinary general meeting, the shareholders of the Company approved the amended stock option 
plan. The amended stock option plan authorizes the Board to also grant sign-on stock options, which vest as follows:

•  1/4th of the stock options granted will vest on the first anniversary of the granting of the stock options, and
•  1/36th of the remaining 3/4th of the stock options granted will vest on the last day of each of the 36 months following the 

month of the first anniversary of the granting of the stock options.

No other conditions are attached to the stock options.

The fair market value of the stock options has been determined based on the Black and Scholes model using the following assumptions:

•  The expected volatility corresponds to the calculated annual volatility of our shares since our initial public offering on Euronext 

Brussels on July 10, 2014 until the date of grant of the options.

•  The average expected option life is determined as a weighted average of the time from grant date to date of becoming exercis-

able and from grant date to expiry of the warrants.

•  Risk free interest rate equals the Belgium 10Year Bond Yield at the date of grant.
•  Expected dividends is considered 0% as we have no plan for distributing dividends and have no history of distributing dividends 

to shareholders.

(1)  On December 20, 2019, the Company granted a total of 921,885 stock options. The beneficiary can choose between a contractual term of five or 
ten years. The average expected option life is currently estimated at six and a half years. This estimate will be reassessed once the acceptance 
period of 60 days has passed and the beneficiaries will have made a choice between a contractual term of five or ten years. The total fair value of 
the grant would range from €49.5 million (100% of the stock options at an expected option life of four years) to €60.6 million (100% of the stock 
options at an expected option life of six and a half years).

14.  Provisions for employee benefits

Our personnel in Belgium participated in a defined contribution plan (extra-legal pension). The Belgian defined contribution pension 
plans were by law subject to minimum guaranteed rates of return, 3.25% on employer contributions and 3.75% on employee 
contributions. These rates, which apply as an average over the entire career, may be modified by Royal Decree. Therefore, those 
plans were basically accounted for as defined contribution plans.

As a consequence of the law of December 18, 2015, minimum returns were guaranteed by the employer as follows: (a) for the 
contributions paid as from January 1, 2016, a new variable minimum return based on OLO rates, with a minimum of 1.75% and a 
maximum of 3.75%. In review of the low rates of the OLO in the last years, the return has been initially set to 1.75%; (b) for the 
contributions paid until end of December 2015, the previously applied legal returns as mentioned above, continue to apply until 
the leaving of the employees.

In view of the minimum returns guarantees, the Belgian defined contribution plans classify as defined benefit plans as from end 
December 2015.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSIn the income statement, current service cost and interest expense or income are included in the operating loss.

The Company’s estimated employer contributions for 2019 amount to €0.3 million compared to €0.2 million in 2018 and €0.3 
million in 2017. Plan assets on December 31, 2019, 2018 and 2017 consisted fully of insurance contracts and did not include direct 
positions in the Company’s shares or bonds, nor do they include any property used by the Company.

The principal actuarial assumption on the balance sheet date (weighted averages based on outstanding defined benefit obligation)

The above analyses were done on a mutually exclusive basis, and holding all other assumptions constant. Through its defined benefit 
plan, the Company is exposed to a number of risks, the most significant of which are detailed below:

Asset volatility
The plan liabilities are calculated using a discount rate set with reference to corporate bond yields; if plan assets underperform 
this yield, this will create a deficit.

Changes in bond yields
A decrease in corporate bond yields will increase plan liabilities, although this will be partially offset by an increase in the value of 
the plan’s bond holdings.

Salary risk
The majority of the plan’s benefit obligations are calculated by reference to the future salaries of plan members. As such, a salary 
increase of plan members higher than expected will lead to higher liabilities.

Longevity risk
Belgian pension plans provide for lump sum payments upon retirement. As such there is limited or no longevity risk.

The weighted average age of the plan participants equals 46.2 years on December 31, 2019, compared to 43.8 years on December 
31, 2018 and 46 years on December 31, 2017.

The accruals for invoices to be received amount to €49.1 million for the year ended December 31, 2019, of which €44.0 million 
relate to invoices to be received from clinical manufacturing organizations for the manufacturing of drug products and from clinical 
research organizations.

Short term employee benefits include payables and accruals for salaries and bonuses to be paid to the employees of the Company.

16.  Tax liabilities

The current tax liability amounts to €0.3 million for the year ended December 31, 2019 and corresponds primarily to the tax payable 
on the result of argenx US, Inc. in view of the transfer price agreements set up between argenx BV and argenx US, Inc.

As part of its business restructuring, the Company transferred the legal ownership of its intellectual property rights from the Dutch 
argenx SE to its wholly owned Belgian subsidiary, argenx BV effective as of January 1, 2017, for an amount of €79.9 million. In 2019, 
the Company has obtained a tax ruling in Belgium which allows for a treatment of the aforementioned amount as a tax deductible 
cost in the Belgian subsidiary.

For the years ended December 31, 2019 and 2018, the majority of the revenue was generated under the agreements with Janssen 
and AbbVie, each as described below. These agreements comprise elements of upfront payments, milestone payments based on 
development criteria and research and development fees.

For the year ended December 31, 2019, €27.3 million related to the collaboration and license agreement with AbbVie was recognized 
in revenue on the basis of costs incurred for this program. Revenue recognized consisted of (i) €0.8 million related to the upfront 
payment received, (ii) €0.4 million related to development milestone payments received in previous years and (iii) €26.1 million 
related to a milestone achieved in 2019. The outstanding balance of deferred revenue amounts to €1.4 million of which €1.2 million 
is recognized as deferred revenue — current and €0.2 million as deferred revenue — non-current. 

Notes to the Consolidated Financial Statements    |  239 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCONSOLIDATED FINANCIAL STATEMENTSFor the year ended December 31, 2019, €21.6 million related to the collaboration and license agreement with Janssen was recog-
nized in revenue on the basis of costs incurred for this program. Revenue recognized consisted of (i) €18.3 million related to the 
upfront payment received, (ii) €1.7 million related to the revenue recognition of deferred income triggered by the accounting 
treatment of the share subscription agreement at the time of signing of the agreement in December 2018 and (iii) €1.6 million 
related to a milestone achieved in 2019. The outstanding balance of deferred revenue amounts to €289.0 million of which €71.1 
million is recognized as deferred revenue — current and €217.9 million as deferred revenue — non-current. 

In total, the Company recognized €1.2 million of revenue that was included in the deferred revenue balance at the beginning of 
the year. As of December 31, 2019, the unsatisfied performance obligations resulting from out-licensing agreements amounted 
to €290.4 million (compared to €2.2 million as of December 31, 2018). Management expects that 25% of the transaction price 
allocated to the unsatisfied performance obligations will be recognized as revenue during the next reporting period. The remaining 
75% will be recognized in financial years 2021 until 2027. The amount disclosed above does not include variable consideration 
which is constrained.

Research and development service fees increased by €17.9 million to €19.3 million for the year ended December 31, 2019 due to 
the research and development service fees recognized under the Janssen collaboration and license agreement.

Below are summaries of the key collaborations.

AbbVie
In April 2016, the Company entered into a collaboration agreement with AbbVie S.À.R.L. (AbbVie) to develop and commercialize 
ARGX-115 (ABBV-151). Under the terms of the collaboration agreement, the Company was responsible for conducting and funding 
all ARGX 115 (ABBV-151) research and development activities up to completion of IND enabling studies.

The Company granted AbbVie an exclusive option, for a specified period following completion of IND enabling studies, to obtain a 
worldwide, exclusive license to the ARGX 115 (ABBV-151) program to develop and commercialize products. The Company received 
an upfront, nonrefundable, non-creditable payment of $40 million (€35.1 million as of the date the payment was received) from 
AbbVie for the exclusive option to license ARGX 115 (ABBV-151). The Company achieved two preclinical milestones, each of which 
triggered a $10.0 million payment (€8.9 million based on the exchange rate in effect as of the date the first milestone payment 
was received, and €8.7 million based on the exchange rate in effect as of the date the second milestone payment was received).

In August 2018, AbbVie exercised its option and has assumed certain development obligations, being solely responsible for all 
research, development and regulatory costs relating to ARGX-115 based products. In March 2019, the Company achieved the first 
development milestone upon initiation of a first-in-human clinical trial, triggering a $30.0 million payment. Subject to the continuing 
progress of ARGX-115 (ABBV-151) by AbbVie, the Company is eligible to receive development, regulatory and commercial milestone 
payments in aggregate amounts of up to $110 million, $190 million and $325 million, respectively, as well as tiered royalties on 
sales at percentages ranging from the mid single digits to the lower teens, subject to customary reductions.

The Company has the right, on a product by product basis to co promote ARGX 115 (ABBV-151) based products in the European 
Economic Area and Switzerland and to combine the product with the Company’s own future immuno oncology programs. The co 
promotion effort would be governed by a co promotion agreement negotiated in good faith by the parties. AbbVie will fund further 
GARP related research by the Company for an initial period of two years. AbbVie will have the right to license additional therapeutic 
programs emerging from this research, for which the Company could receive associated milestone and royalty payments.

240  |  Notes to the Consolidated Financial Statements

With regard to its collaboration with AbbVie, the Company concluded as follows:

•  There is one single performance obligation under IFRS 15, that being the transfer of a license combined with performance of 
research and development activities. The Company concluded that the license is not distinct in the context of the contract.
•  The transaction price of these two agreements is currently composed of a fixed part, that being an upfront license fee, and 
a variable part, that being milestone payments and cost reimbursements of research and development activities delivered. 
Milestone payments are only included in the transaction price as from the moment the achievement of the related milestone 
event is highly probable (usually at the time of achievement of the milestone event). Sales-based milestones and sales-based 
royalties are a part of the Company’s arrangements but are not yet included in its revenues, as its programs with AbbVie is still 
in the development phase.

•  The transaction price has been allocated to the single performance obligation, and revenues have been recognized over the 
estimated service period based on a pattern that reflects the transfer of the license and progress to complete satisfaction of 
the research and development activities. This is because the transfer of the license is considered to be combined with the 
performance of research and development activities. Therefore, research and development milestone payments are variable 
considerations that are entirely allocated to the single performance obligation.

•  The Company has chosen an input model to measure the satisfaction of the single performance obligation that considers 

percentage of costs incurred for these programs (percentage of completion method).

•  Cost reimbursements received could be recognized in revenues when costs are incurred and agreed by the parties, as the 
Company is acting as a principal in the scope of its stake of the research and development activities of its ongoing license and 
collaboration agreements.

Janssen
In December 2018, the Company entered into a collaboration agreement with Cilag GmbH International, an affiliate of Janssen, 
to jointly develop and commercialize cusatuzumab. The Company has granted Janssen a license to the cusatuzumab program to 
develop, manufacture and commercialize products. For the U.S., the granted commercialization license is co-exclusive with argenx, 
while outside the U.S., the granted license is exclusive. Janssen and argenx will assume certain development obligations, and will 
be jointly responsible for all research, development and regulatory costs relating to the products. argenx will be eligible to receive 
potentially up to $1.3 billion in development, regulatory and sales milestones, in addition to tiered royalties, ranging from the low 
double digits to the high teens. Janssen will be responsible for commercialization worldwide. argenx retains the option to participate 
in commercialization efforts in the US, where the companies have agreed to share royalties on a 50/50 basis, and outside the U.S., 
Janssen will pay sales royalties ranging from the low double digits to the high teens to argenx.

Under the terms of the agreement, Janssen committed to an upfront payment of $500 million consisting of a license payment of 
$300 million and a $200 million equity investment in the Company by subscribing to 1,766,899 new shares at a price of €100.02 
per share, including an issuance premium. The agreement became effective in January 2019 following expiration of the waiting 
period under the Hart-Scott-Rodino Antitrust Improvements Act. In December 2019, the Company achieved the first development 
milestone, triggering a $25.0 million payment.

With regard to this collaboration with Janssen, the Company concluded as follows:

•  There is one single performance obligation under IFRS 15, that being the transfer of a license combined with performance of 
research and development activities. The Company concluded that the license is not distinct in the context of the contract. 
Moreover, the Company concluded that the share premium that Janssen paid above the closing price on the day of entering 
into the investment agreement (being December 2, 2018) was paid because of the existing obligations to deliver development 
services under the terms of the collaboration agreement, and is therefore to be allocated to the single performance obligation.
•  The transaction price of this agreement is currently composed of a fixed part, that being an upfront license fee and the share 
premium, and a variable part, that being milestone payments and cost reimbursements of research and development activities 
delivered. Milestone payments are only included in the transaction price as from the moment the achievement of the related 
milestone event is highly probable (usually at the time of achievement of the milestone event). Sales-based milestones and 
sales-based royalties are a part of the Company’s arrangements but are not yet included in its revenues, as its program with 
Janssen are still in the development phase.

The total cash outflow for leases in 2019 was €1.6 million. The Company’s new accounting policy for leases is described in note 2.6.

The Company did not enter into any lease agreement with variable lease payments or residual value guarantees. The Company has 
leases that include extension options. These options provide flexibility in managing the leased assets and align with the Company’s 
business needs. The Company exercises judgement in deciding whether it is reasonably certain that the extension options will be 
exercised. The Company leases offices and laboratory space in Zwijnaarde, Belgium. The contract contains an extension option for 
three years. The Company also leases office space in Boston, Massachusetts. The contract contains an extension option for five years.

The Company has entered into an additional lease for office space in Tokyo, Japan in January 2020. The minimum lease term of 
three years and two months results in a contractually agreed cash outflow of ¥ 233.5 million (€1.9 million).

The tax rate used for the 2019, 2018 and 2017 reconciliations above is the corporate income tax rate of 25% payable by corporate 
entities in the Netherlands.

The unrecognized deferred tax asset on deductible temporary differences and unused tax losses amounts to €40.0 million on 
December 31, 2019, compared to €29.3 million on December 31, 2018. Deferred tax have been measured using the effective rate 
that will apply in Belgium (25%). The Company has unused tax losses carried forward for an amount of €160.0 million on December 
31, 2019 (compared to €117.1 million on December 31, 2018), of which €1.4 million will expire in 2028. This, combined with other 
temporary differences, resulted in a net deferred tax asset position. Due to the uncertainty surrounding the Company’s ability to 
realize taxable profits in the near future, the Company did not recognize any deferred tax assets. 

As part of its business restructuring, the Company transferred the legal ownership of its intellectual property rights from the Dutch 
argenx SE to its wholly owned Belgian subsidiary, argenx BV, effective as of January 1, 2017, for an amount of €79.9 million. In 2019, 
the Company has obtained a tax ruling in Belgium which allows for a treatment of the aforementioned amount as a tax deductible 
cost in the Belgian subsidiary.

Earnings/losses per ordinary share are calculated by dividing the loss for the period by the weighted average number of ordinary 
shares during the year.

As the Company is suffering operating losses, options have an anti dilutive effect. As such, there is no difference between basic 
and diluted earnings/losses per ordinary share. There are no other instruments that could potentially dilute earnings per ordinary 
share in the future.

(1)  The Company adopted IFRS 9 on January 1, 2018. Under IAS 39, non-current financial assets were measured as “Available for sale”.

248  |  Notes to the Consolidated Financial Statements

Current financial assets included collective investment funds nominated in € and $ that are not considered as cash equivalents and of 
which the underlying investments include bonds and other international debt securities. The average credit rating of the underlying 
instruments is BBB or higher. The maximum exposure to credit risk is the carrying value at reporting date. These investment funds 
are recognized at fair value in the Company’s consolidated financial statements (level 1). The fair value corresponds to the quoted 
market price and can therefore be classified as a level 1 fair value measurement. The net asset value (NAV) of the funds is available 
on a daily basis. Any difference between amounts invested and fair value at reporting date is booked in Profit & Loss.

Due to the current nature of the financial liabilities, the nominal value of all financial liabilities presented above approximates their 
fair value.

The Company carried the following assets at fair value on December 31, 2019, 2018 and 2017 respectively:

During the disclosed calendar year no transfers occurred between the applicable categories. 

In March 2019, the Company entered into a license agreement with AgomAb Therapeutics NV for the use of HGF-mimetic SIMPLE 
Antibodies™, developed under the Company’s Innovative Access Program. In exchange for granting this license, the Company 
received a profit share in AgomAb Therapeutics NV. The profit share has been designated as a non-current financial asset held at 
fair value through profit or loss. Since AgomAb Therapeutics NV is a private company, the valuation of the profit share is based on 
level 3 assumptions.

Capital risk
The Company manages its capital to ensure that it will be able to continue as a going concern. The capital structure of the Company 
consists of equity attributed to the holders of equity instruments of the Company, such as capital, reserves and accumulated losses 
as mentioned in the consolidated statement of changes in equity. The Company makes the necessary adjustments in the light of 
changes in the economic circumstances, risks associated to the different assets and the projected cash needs of the current and 
projected research activities. On December 31, 2019, cash and cash equivalents amounted to €331.3 million and total capital

amounted to €1,312.8 million. The current cash situation and the anticipated cash generation are the most important parameters 
in assessing the capital structure. The Company’s objective is to maintain the capital structure at a level to be able to finance its 
activities for at least twelve months. Cash income from existing and new partnerships is taken into account and, if needed and 
possible, the Company can issue new shares or enter into financing agreements.

Credit risk
Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Company. 
The Company has adopted a policy of only dealing with creditworthy counterparties and obtaining sufficient collateral, where 
appropriate, as a means of mitigating the risk of financial loss from defaults. Concentrations in credit risk are determined based on 
an analysis of counterparties and their importance on the overall outstanding contractual obligations at year end.

The Company has a limited number of collaboration partners and therefore has a significant concentration of credit risk. However, 
it has policies in place to ensure that credit exposure is kept to a minimum and significant concentrations of credit exposure are 
only granted for short periods of time to high credit quality collaboration partners.

Credit exposure is controlled by counterparty limits that are reviewed and approved by management annually.

Cash and cash equivalents and short term deposits are invested with several highly reputable banks and financial institutions. The 
Company holds its cash and cash equivalents mainly with different banks which are independently rated with a minimum rating 
of ‘A-’.

The Company also holds short term investment funds in the form of money market funds with a recommended investment horizon 
of 6 months or shorter but with a low historical volatility. These money market funds are highly liquid investments, can be readily 
convertible into a known amount of cash. Since they are a basket of funds there is no individual credit risk involved.

The average credit rating of the underlying instruments for the investment funds is BBB or higher.

The maximum credit risk, to which the Company is theoretically exposed as at the balance sheet date, is the carrying amount of 
the financial assets.

At the end of the reporting period no financial assets were past due, consequently no financial assets were subject to impairment.

Liquidity risk
The Company manages liquidity risk by maintaining adequate reserves, by continuously monitoring forecast and actual cash flows, 
and by matching the maturity profiles of financial assets and liabilities.

The Company’s main sources of cash inflows are obtained through capital increases and collaboration agreements. This cash is 
invested in savings accounts, term accounts and short term investment funds in the form of money market funds. These money 
market funds represent the majority of the Company’s available sources of liquidity however since all of these are immediately 
tradable and convertible in cash they have a limited impact on the liquidity risk.

All financial liabilities (principally trade and other payables as disclosed in note 27) have a maturity within 3 months unless otherwise 
disclosed in these consolidated financial statements.

Interest rate risk
The only interest bearing financial assets are cash at banks on deposit and term accounts. For the year ended December 31, 2019, 
if applicable interest rates would increase/decrease by 25 basis points, this would have a positive/negative impact of €2.0 million 
(compared to €0.3 million for the year ended December 31, 2018 and €0.3 million for the year ended December 31, 2017).

250  |  Notes to the Consolidated Financial Statements

Foreign exchange risk
The Company undertakes transactions denominated in foreign currencies; consequently, exposures to exchange rate fluctuations 
arise. The Company is mainly exposed to the U.S. Dollar, Japanse yen, British pound and Swiss franc. To limit this risk, the Company 
attempts to align incoming and outgoing cash flows in currencies other than EUR.

The net exposure to exchange differences of the monetary assets (being cash, cash equivalents and current financial assets) of the 
Company at the end of the reporting period are as follows:

On December 31, 2019, if the USD/EUR exchange rate would have increased/decreased by 10%, this would have had a negative/
positive impact of €74.72 million (compared to €28.44 million on December 31, 2018). On December 31, 2019, if the exchange rate 
for other currencies would have increased/decreased by 10% , this would have had no significant impact.

28.  Related party transactions

Balances and transactions between the Company and its subsidiaries, which are related parties of the Company, have been elim-

period, other than compensation of key management personnel.

Compensation of key management personnel
Key management personnel of the Company is composed of the Chief Executive Officer, the Chief Financial Officer, the Chief 
Operating Officer, the Chief Scientific Officer, the Chief Medical Officer, the Vice President of Corporate Development & Strategy 
and the General Counsel.

share-based payment expense recognized in the consolidated statement of comprehensive income totaled €14.4 million for the year ended 
December 31, 2019, compared to €10.7 million for the year ended December 31, 2018 and €2.3 million for the year ended December 31, 2017

(2)  The Company incurs employer social security costs with respect to the option awards granted to certain members of the executive management. 

The amount of employer social security costs depends on the actual economic value realized and therefore varies based on our stock price. At each 
reporting date, the Company makes a calculation of the exposure.

employer social security costs depends on the actual economic value realized and therefore varies based on our stock price. At each reporting date, 
the Company makes a calculation of the exposure.

(2)  Consists of rent paid by the Company, costs attributable to the lease of a company car and employer-paid medical insurance premiums.

The table below shows the number of stock options granted to the executive directors during the years ended December 31, 2019, 
2018 and 2017 and their exercise price equal to the fair market value upon date of grant, and the stock options exercised during 
2019, 2018 and 2017.

29.  Contingencies

The Company is currently not facing any outstanding claims or litigations that may have a significant adverse impact on the 
Company’s financial position.

As described in note 18 the Company has received several types of government grants which are granted subject to a certain 
number of conditions that need to be met at grant date and in the future. The Company recognizes grant income from Belgian and 
Flemish grant bodies when all contractual conditions are met. These government institutions may however subsequently perform 
an audit which may result in a (partial) claw back of the grant. The Company deems that the claw back risk is remote in view of the 
continuous monitoring of the contractual conditions. The Company has fulfilled all existing conditions relating to the recognition 
of its grant income. 

Contracts with these grant bodies also typically include clauses that define the need for future validation of the project results 
after completion of the initial grant term during which the subsidized expenses or investments have been incurred and for which 
the grant was earned. Should this validation not occur or be deemed inadequate, the grant bodies have the right to reclaim funds 
previously granted.

As described in note 8, in 2019, the Company granted a total of 1,365,172 stock options to certain of its employees, Board members 
and consultants. As part of the grant of these stock options, the Company has undertaken to compensate Belgian taxes that are 
paid upon the grant of these stock options if and when at the end of the exercise period, the stock price would be lower than the 
exercise price, as increased with these taxes. The Company has applied for a tax ruling on this subject that would cover the stock 
option grants as from June 28, 2018. The exposure that the Company could face at the end of the exercise period for the stock 
options granted in 2018 and 2019 ranges from €7.6 million to €8.6 million.

30.  Commitments

At balance sheet date, there were no commitments signed for the acquisition of property, plant and equipment. In February 
2019, the Company entered into a global collaboration and license agreement with Halozyme Therapeutics, Inc. Under the terms 
of the agreement, the Company will pay $10.0 million per target for future target nominations and potential future payments of 
up to $160.0 million per selected target subject to achievement of specified development, regulatory and sales-based milestones 
and up to $40.0 million subject to the achievement of additional, specified sales-based milestones. This amount represents the 
maximum amount that would be paid if all milestones would be achieved but excludes variable royalty payments based on unit 
sales. For the year ended December 31, 2019, the Company exercised the option to nominate an additional target (triggering a $10 
million development milestone payment) and initiated a Phase 1 clinical trial using Halozyme’s proprietary ENHANZE® drug delivery 
technology (triggering a $5 million development milestone payment).

The Company’s manufacturing commitments with its drug substance manufacturing contractor Lonza relate to the ongoing execu-
tion of the BLA services for efgartigimod and the ongoing manufacturing activities related to the start-up of Lonza Singapore as a 
potential future commercial manufacturing site. In December 2018, the Company signed its first commercial supply agreement 
with Lonza related to the reservation of commercial drug substance supply capacity for efgartigimod. The total commitment under 
this commercial supply agreement amounts to a minimum commitment of £25.3 million over a period of five years starting from 
2020. In the aggregate, the Company has outstanding commitments for efgartigimod of approximately €53.4 million. In addition 
to the obligations for efgartigimod, the Company also has contractual obligations for cusatuzumab of approximately €34.4 million 
and for ARGX-117 of approximately €3.6 million.

33.  Events after the balance sheet date

The recent outbreak of COVID-19 originated in Wuhan, China, in December 2019 and has since spread to multiple countries, including 
the United States and several European countries. On March 11, 2020, the World Health Organization declared the outbreak a 
pandemic. The spread of COVID-19 has impacted the global economy and may impact our operations, including the potential 
interruption of our clinical trial activities and our supply chain. For example, the COVID-19 outbreak may delay enrollment in our 
clinical trials due to prioritization of hospital resources toward the outbreak, and some patients may be unwilling to enroll in our 
trials or be unable to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services, 
which would delay our ability to conduct clinical trials or release clinical trial results. The spread of an infectious disease, including 
COVID-19, may also result in the inability of our suppliers to deliver clinical drug supplies on a timely basis or at all. In addition, 
hospitals may reduce staffing and reduce or postpone certain treatments in response to the spread of an infectious disease. Such 
events may result in a period of business disruption, and in reduced operations, or doctors and medical providers may be unwilling 
to participate in our clinical trials, any of which could materially affect our business, financial condition and results of operations. 
The extent to which the recent global COVID-19 pandemic impacts our business will depend on future developments, which are 
highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19 and the 
actions to contain or treat its impact, among others. Any significant infectious disease outbreak, including the COVID-19 pandemic, 
could result in a widespread health crisis that could adversely affect the economies and financial markets worldwide, resulting in 
an economic downturn that could impact our business, financial condition and results of operations, including our ability to obtain 
additional funding, if needed. The Company is proactively executing risk mitigation strategies to attenuate the impact of COVID-19.

Notes to the Company Financial Statements 
of argenx SE

1. 

Accounting Information and Policies

B ASIS OF PREPARATION

The company financial statements of argenx SE (hereafter: the company) have been prepared in accordance with Part 9, Book 2 of 
the Dutch Civil Code. In accordance with article 362 sub8, Book 2 of the Dutch Civil Code, the company’s financial statements are 
prepared based on the accounting principles of recognition, measurement and determination of profit, as applied in the consolidated 
IFRS financial statements.

SUMMARY OF SIGNIFICANT ACCOU N TI N G PO LI C I ES

In case no other policies are mentioned, refer to the accounting policies as described in the summary of significant accounting 
policies in the consolidated IFRS financial statements. For an appropriate interpretation, the company financial statements of argenx 
SE should be read in conjunction with the consolidated IFRS financial statements.

Participating interests in group companies
Participating interests in group companies are valued using the equity method, applying the IFRS accounting policies endorsed 
by the European Union. Following the adoption of IFRS 9 by the group, and our interpretation of the Dutch Accounting Standard 
100.107A, the company shall, upon identification of a credit loss on an intercompany loan and/or receivable, eliminate the carrying 
amount of the intercompany loan and/or receivable for the value of the identified credit loss.

Result of participating interests
The share in the result of participating interests consists of the share of the Company in the result of these participating interests. 
In so far as gains or losses on transactions involving the transfer of assets and liabilities between the Company and its participating 
interests or between participating interests themselves can be considered unrealized, they have not been recognized.

All amounts are presented in thousands of euro, unless stated otherwise. The balance sheet and income statement references have 
been included. These refer to the notes.

Correction of an immaterial error
Subsequent to the issuance of the company’s financial statements for the year ended December 31, 2018, the company determined 
that the intercompany recharges resulting from a cross-charge of transaction costs incurred in a follow-on offering in September 
2018 to the subsidiary argenx BV should not have been presented as “Intercompany Recharges”, thereby impacting the company 
profit and loss account. Management evaluated the materiality of the errors from a quantitative and qualitative perspective and 
concluded that this adjustment was not material to the company’s previously issued financial statements. The company has elected 
to revise the historical financial information presented herein in the company profit and loss account to reflect the correction of 
this error for the prior period presented and to confirm to current year presentation. Since the revisions were not material, no 
amendments to previously filed reports were required. The revision had the effect of decreasing “Intercompany Recharges” and 
increasing “Share in result of subsidiaries” with €14.9 million as of December 31, 2018.

materiality is based on 3% of operating expenses. We have also taken into account misstatements and/or possible misstatements 
that in our opinion are material for the users of the financial statements for qualitative reasons.

We agreed with the Board of Directors that misstatements in excess of € 390.000, which are identified during the audit, would be 
reported to them, as well as smaller misstatements that in our view must be reported on qualitative grounds. 

SCOPE OF THE GROUP AUDIT

argenx SE is at the head of a group of entities. The financial information of this group is included in the consolidated financial 
statements of argenx SE.

Because we are ultimately responsible for the opinion, we are also responsible for directing, supervising and performing the group 
audit. In this respect we have determined the nature and extent of the audit procedures to be carried out for group entities. The 
audit procedures on all group entities have been performed by the group engagement team. By performing these procedures, we 
have been able to obtain sufficient and appropriate audit evidence about the group’s financial information to provide an opinion 
about the consolidated financial statements.

EMPHA SIS OF A MATT ER

As discussed in Note 33 to the financial statements, the Company has described the potential effects of the coronavirus disease 
2019 (COVID-19) on the operations of the business. Our opinion is not modified in respect of this matter.

OUR KEY AUDIT MATT ERS

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial 
statements. We have communicated the key audit matters to the Board of Directors. The key audit matters are not a comprehensive 
reflection of all matters discussed.

These matters were addressed in the context of our audit of the financial statements as a whole and in forming our opinion thereon, 
and we do not provide a separate opinion on these matters.

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCOMPANY FINANCIAL STATEMENTSRevenue and Deferred Revenue - Determination of appropriate accounting of the global collaboration and license 
agreement - Refer to Note 17 to the financial statements

DESCRIPTION

OUR RESPONSE

The Company recognized revenue of EUR 21.6 million on the basis of 
costs incurred and deferred revenue of EUR 289 million related to a 
global collaboration and license agreement entered into with Cilag 
AG, an affiliate of Johnson & Johnson as of and for the year ended 
December 31, 2019. The Company received USD 500 million as upfront 
payment for this collaboration and license agreement, consisting of 
USD 300 million upfront cash payment for the collaboration and license 
agreement and USD 200 million as equity investment in the Company. 

The Company’s collaboration and license agreement has been 
determined as representing a single distinct performance obligation, 
due to the highly interdependent and interrelated nature of the 
development, manufacturing, and commercialization of the Licensed 
Compounds and Licensed Products.

Fulfillment of the performance obligation occurs throughout the 
development, manufacturing, and commercialization phases of the 
Licensed Compounds and Licensed Products.

The Company recognizes the consideration received as deferred revenue 
and subsequently recognizes revenue over the contract term (“over 
time”) based on a research and development (“R&D”) cost input model 
using a percentage-of-completion method, whereby actual R&D cost 
incurred as part of the Company’s performance obligation is compared 
to the total expected R&D cost needed to satisfy the performance 
obligation at measurement date.

In determining the appropriate accounting treatment, the Company 
identified multiple performance obligations and concluded the license 
is not distinct from the promise to provide R&D services in the context 
of the contract. Given the subjective nature of this judgement and the 
potential impact on the revenue to be recognized, we identified the 
evaluation as to whether any promises or services described in the 
collaboration agreement should be considered as a distinct performance 
obligation in the context of the contract as a key audit matter.

Our audit procedures for the accounting of the collaboration and license 
agreement included the following, among others:

•  We tested the controls over the appropriateness of the accounting of 
the global collaboration and license agreement, including the review 
by management of the appropriate accounting treatment.

•  We read the global collaboration and license agreement and 

evaluated whether management’s accounting position considered all 
relevant facts and terms included in the agreement.

•  We further evaluated management’s accounting position paper 
and evaluated management’s conclusions to determine whether 
they had appropriately considered and applied the guidance and 
interpretation within IFRS 15.

•  We have consulted with financial reporting experts on the critical 

judgements and the accounting treatment of the global collaboration 
and license agreement.

•  We tested the mathematical accuracy of the deferred revenue 

position based on the revenue recognized and the total deferred 
revenue at inception of the contract.

OBSERVATIONS

The scope and nature of the audit procedures we performed was 
sufficient and appropriate to address the risks of material misstatement 
resulting from the global collaboration and license agreements.

Trade and Other Payables - Research and development cost accruals — Refer to Note 15 to the financial 
statements

DESCRIPTION

OUR RESPONSE

The Company recognizes costs of EUR 44.0 million, as specified in 
Note 15 to the financial statements, incurred for clinical trial activities 
as research and development expenses based on evaluation of its 
vendors’ progress toward completion of specific tasks. Payment 
timing may differ significantly from the period in which the costs are 
recognized as expense, resulting in Research and development cost 
accruals recognized within Trade and Other Payables in the Statement of 
Financial Position.

Quantification of the research progress and the translation of the 
progress to the Research and development cost accruals requires 
judgment, because the progress is not directly observable. In estimating 
the vendors’ progress toward completion of specific tasks, the Company 
therefore uses data such as patient enrollment, clinical site activations 
and vendor information of actual costs incurred. This data is obtained 
through reports from or discussions with Company personnel and 
outside service providers as to the progress or state of completion of 
trials, or the completion of services. Costs are expensed over the service 
period the services are provided. Costs for services provided that have 
not yet been paid are recognized as accruals. R&D cost accruals directly 
impact the revenue recognized, given the Company records revenue 
based on the percentage of completion method. 

We identified the Research and development cost accruals as a key 
audit matter due to the number of ongoing clinical trial activities and 
the subjectivity involved in estimating Research and development cost 
accruals and as auditing the Research and development cost accruals 
involves judgement in evaluating the progress of the research and 
development activities relative to the costs incurred.

Our audit procedures related to the Research and development cost 
accruals included the following, among others:

•  We tested controls over the appropriateness of the recording of the 
R&D accruals reflecting the progress of the clinical trials, including 
the monthly review meetings between the finance department and 
clinical research personnel.

•  We read selected research and collaboration agreements, as well 
as amendments thereto, to evaluate whether the progress of the 
clinical trials reflects all relevant contractual elements. 

•  We considered publicly available information (such as press releases 

and investor presentations) and board of directors’ materials 
regarding the status of clinical trial activities and compared this 
information to the judgements applied in recording the accruals and 
prepaid expenses.

•  For a selection of contracts, we compared the amount of accrual at 

the end of the prior period to current year activity and evaluated the 
accuracy of the Company’s estimation methodology. 

•  We performed confirmation procedures related to the progress of 

the projects for significant vendors to test the R&D cost input model.

•  We made selections of specific amounts recognized as R&D expense 
as well as those recognized as accrued expenses and performed the 
following procedures:

•  Evaluated management’s estimate of the vendor’s progress 

based on inquiries with Company clinical operations personnel.

•  Reconciled the related statement of work, purchase order, or 
other supporting documentation to management’s estimate 
(such as communications between the Company and vendors).

OBSERVATIONS

The scope and nature of the audit procedures we performed was 
sufficient and appropriate to address the risks of material misstatement 
related to the Research and development cost accruals.

Description of Responsibilities Regarding the Financial Statements

RESPONSIBILITIES OF MANAGE ME N T AN D T HE B OAR D O F DI R ECTOR S FOR TH E F I N AN CI AL 
STATE ME NTS

Management is responsible for the preparation and fair presentation of the financial statements in accordance with EU-IFRS 
and Part 9 of Book 2 of the Dutch Civil Code. Furthermore, management is responsible for such internal control as management 
determines is necessary to enable the preparation of the financial statements that are free from material misstatement, whether 
due to fraud or error.

As part of the preparation of the financial statements, management is responsible for assessing the company’s ability to continue 
as a going concern. Based on the financial reporting frameworks mentioned, management should prepare the financial statements 
using the going concern basis of accounting unless management either intends to liquidate the company or to cease operations, 
or has no realistic alternative but to do so. 

278  |  Independent Auditor’s Report

Management should disclose events and circumstances that may cast significant doubt on the company’s ability to continue as a 
going concern in the financial statements.

The Board of Directors is responsible for overseeing the company’s financial reporting process.

OUR RESPONSI BI LITIES FOR THE AU DI T O F T HE F I N AN C I AL STATEM EN T S

Our objective is to plan and perform the audit assignment in a manner that allows us to obtain sufficient and appropriate audit 
evidence for our opinion.

Our audit has been performed with a high, but not absolute, level of assurance, which means we may not detect all material errors 
and fraud during our audit.

Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably 
be expected to influence the economic decisions of users taken on the basis of these financial statements. The materiality affects 
the nature, timing and extent of our audit procedures and the evaluation of the effect of identified misstatements on our opinion.

We have exercised professional judgement and have maintained professional skepticism throughout the audit, in accordance with 
Dutch Standards on Auditing, ethical requirements and independence requirements. Our audit included, but was not limited to, 
the following:

• 

Identifying and assessing the risks of material misstatement of the financial statements, whether due to fraud or error, designing 
and performing audit procedures responsive to those risks, and obtaining audit evidence that is sufficient and appropriate to 
provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one 
resulting from error, as fraudsters generally try to hide the implications of their fraud. Committing fraud and the hiding thereof 
may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal controls. In identifying 
potential risks of material misstatement due to fraud, we evaluated the groups’s risk assessment, had inquiries with manage-
ment, those charged with governance and other within the group, including but not limited to, general counsel, global quality 
assurance and financial control & corporate accounting. We involved a forensic specialist in our identification of fraud risk factors. 
Following these procedures, and the presumed risks under the prevailing auditing standards, we considered the fraud risks in 
relation to management override of controls. As part of our audit procedures to respond to these fraud risks, we evaluated the 
internal controls relevant to mitigate these risks and performed supplementary substantive audit procedures, including detailed 
testing of journal entries and supporting documentation in relation to post-closing adjustments. Data analytics, including testing 
journal entries based on certain risk-based characteristics, is part of our audit approach to address fraud risks.

We obtained written representations that all known instances of (suspected) fraud or non-compliance with laws and regulations 
have been disclosed to us.

• 

Identifying and assessing the relevant risks and effects from non-compliance with laws and regulations as SEC regulations, Dutch 
Stock exchange regulations, FDA regulations, EMA regulations, financial reporting regulations, corporate tax law and the require-
ments under part 9 of Book 2 of the Dutch Civil Code with a direct effect on the financial statements to the extent material for 
the financial statements of The Company. Apart from these, The Company is subject to other laws and regulations where the 
consequences of non-compliance could have a material effect on amounts and/or disclosures in the financial statements, for 
instance through imposing fines or litigation. As a response to relevant non-compliance risks, we evaluated the related internal 
controls to identify non-compliance with the relevant laws and regulations and performed audit proicedures that address these 
non-compliance risks. Our procedures included inquiries of management, those charged with governancen and other within 
the group and we inspected board minutes, correspondence with relevant authorities and lawyers’ letters. We also remained 
alert to indications of (suspected) non-compliance throughout the audit. We obtained written representations that all known 
instances of non-compliance with laws and regulations have been disclosed to us.

•  Obtaining an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate 
in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company’s internal control.

Independent Auditor’s Report    |  279 

PART I - PART II - PART III - PART IV - PART V - PART VI - PART VII - PART VIII - PART IXCOMPANY FINANCIAL STATEMENTS•  Evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclo-

sures made by management.

•  Concluding on the appropriateness of management’s use of the going concern basis of accounting, and based on the audit 
evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the 
company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw 
attention in our auditor’s report to the related disclosures in the financial statements or, if such disclosures are inadequate, to 
modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, 
future events or conditions may cause the company to cease to continue as a going concern.

•  Evaluating the overall presentation, structure and content of the financial statements, including the disclosures. 
•  Evaluating whether the financial statements represent the underlying transactions and events in a manner that achieves fair 

presentation.

We communicate with the Board of Directors regarding, among other matters, the planned scope and timing of the audit and 
significant audit findings, including any significant findings in internal control that we identified during our audit. In this respect we 
also submit an additional report to the audit committee in accordance with Article 11 of the EU Regulation on specific requirements 
regarding statutory audit of public-interest entities. The information included in this additional report is consistent with our audit 
opinion in this auditor’s report.

We provide the Board of Directors with a statement that we have complied with relevant ethical requirements regarding inde-
pendence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our 
independence, and where applicable, related safeguards.

From the matters communicated with the Board of Directors, we determine the key audit matters: those matters that were of most 
significance in the audit of the financial statements. We describe these matters in our auditor’s report unless law or regulation 
precludes public disclosure about the matter or when, in extremely rare circumstances, not communicating the matter is in the 
public interest.
