Breda, the Netherlands / Ghent, Belgium
– argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases and cancer, today announced its financial results for the third quarter ended September 30, 2020 and provided a business update.

“It has been an important year for argenx, marked by a number of significant achievements that position us to file our first BLA for efgartigimod as a new treatment for gMG by year-end. We remain focused on both the BLA filing and commercial preparations as we work to bring efgartigimod to patients as soon as possible,” said Tim Van Hauwermeiren, CEO of argenx. “We have built an exceptional team, established our global supply chain and connected with physicians, payors and patient advocacy groups – all critical elements for a successful commercial launch.”

“We are building a broad FcRn antagonist program by leveraging the potential of efgartigimod across a number of important indications where there is a high unmet need for innovation. Our global Phase 3 ADDRESS trial in pemphigus is on track to start soon and, as we did with the ADAPT trial in MG, we have carefully designed the trial alongside patients and physicians to best address the complex challenges presented by this serious disease. We continue to ground our pipeline expansion strategy in biology, working from the science to address severe autoimmune diseases and advance our ‘argenx 2021’ vision across our emerging franchises,” continued Mr. Van Hauwermeiren.


Preparations underway to support potential approval and launch of FcRn antagonist, efgartigimod, in gMG in U.S., Japan and EU

  • BLA on track to be filed with the FDA by the end of 2020 with an expected U.S. commercial launch in 2021
  • Japanese Marketing Authorization Application (J-MAA) expected to be filed with the Pharmaceuticals and Medical Devices Agency (PMDA) in the first half of 2021 with an anticipated Japan commercial launch in 2022
  • Regulatory filing in the EU to follow filing in Japan
  • Pre-commercial launch activities underway, including global supply chain creation, and physician, payor and patient advocacy engagement

Presented supportive data from global Phase 3 ADAPT trial of efgartigimod in gMG at recent medical meetings, showing rapid and clinically meaningful responses to efgartigimod and a safety profile comparable to placebo

  • Results from Phase 3 ADAPT trial presented at Myasthenia Gravis Foundation of America (MGFA) 2020 Virtual Scientific Session and American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2020 Virtual Annual Meeting were consistent with previously announced positive topline results
  • New data analyses presented on significant magnitude and repeatability of response, clinical benefit in antibody-negative patients and validation of proposed mechanism of action, with notable reductions in total IgG and pathogenic autoantibody levels

Broad efgartigimod development plan progressing with Phase 2 trial of fifth indication expected to start in mid-2021

  • Within neuromuscular franchise, efgartigimod is being developed for gMG and CIDP
    • FDA discussions to occur by end of 2020 to inform bridging strategy for SC efgartigimod for the treatment of gMG
      • Path forward to be communicated after alignment with FDA
    • Phase 2 ADHERE trial of SC efgartigimod for the treatment of CIDP is ongoing
      • Decision to expand trial after analysis of first 30 patients now expected in first half of 2021 due to enrollment delays caused by COVID-19
  • Within hematology franchise, efgartigimod is being developed for primary immune thrombocytopenia (ITP)
    • Communication with FDA planned to discuss development of SC efgartigimod
    • Updated plan for registration program to include two trials to run concurrently

    • Global Phase 3 ADDRESS trial evaluating SC efgartigimod in up to 150 pemphigus patients to initiate by end of 2020
    • Trial to evaluate efficacy and safety, including potential to drive fast onset of disease control and complete remission and the ability to taper corticosteroids
  • Preparations underway to initiate Phase 2 trial in fifth rare disease indication by mid-2021
    • Indication details, including on biology rationale, Phase 2 trial design and commercial opportunity, to be shared during investor event in first half of 2021

Continued investment in Immunology Innovation Program to build pipeline of first-in-class antibodies against immunologic targets

  • New partnerships announced with Chugai and the Clayton Foundation to expand argenx’s access to innovative antibody engineering technologies and to enhance its capabilities to build future antibody candidates with sweeping and half-life extending characteristics
  • Collaboration with Halozyme for ENHANZE® drug delivery technology expanded to include three additional exclusive targets upon nomination bringing the total to six potential targets

Net increase in cash, cash equivalents and current financial assets compared to year-end 2019  468,223             358,679   
Cash, cash equivalents and current financial assets at the end of the period  1,804,043             923,248   


Cash, cash equivalents and current financial assets totaled €1,804.0 million on September 30, 2020, compared to €1,335.8 million on December 31, 2019. The increase in cash and cash equivalents and current financial assets resulted primarily from the closing of a global offering, including a U.S. offering and a European private placement, which resulted in the receipt of €730.7 million in net proceeds in June 2020, and net cash flows used in operating activities.

Total operating income decreased by €18.6 million for the nine months ended September 30, 2020 to €42.6 million, compared to €61.2 million for the nine months ended September 30, 2019. The decrease was due to the milestone payments following the first-in-human clinical trial with ABBV-115 under the AbbVie collaboration which was achieved in the nine months ended September 30, 2019. This was partly offset by higher revenue recognition of the transaction price related to the Janssen collaboration and the increase in other income driven by higher payroll tax rebates for employing certain research and development personnel.

Research and development expenses increased by €123.5 million for the nine months ended September 30, 2020 to €246.3 million, compared to €122.8 million for the nine months ended September 30, 2019. The increase in the first nine months of 2020 resulted primarily from higher external research and development expenses, primarily related to the efgartigimod program in various indications, the cusatuzumab program and other clinical and preclinical programs. Furthermore, the personnel expenses increased due to a planned increase in headcount.

Selling, general and administrative expenses totaled €100.4 million for the nine months ended September 30, 2020, compared to €41.7 million for the nine months ended September 30, 2019. The increase resulted primarily from higher personnel expenses and consulting fees related to the preparation of a possible future commercialization of argenx’s lead product candidate efgartigimod.

For the nine months ended September 30, 2020, financial expenses, which primarily relate to interest received and changes in fair value of current financial assets, amounted to €1.7 million, compared to a financial income of €10.8 million for the nine months ended September 30, 2019. Financial expenses corresponded mainly to a decrease in net asset value of current financial assets following the impact of the COVID-19 outbreak on the financial markets.

Exchange losses totaled €55.9 million for the nine months ended September 30, 2020, compared to an exchange gain of €26.9 million for the nine months ended September 30, 2019. The change is mainly attributable to unrealized exchange rate losses on the cash, cash equivalents and current financial asset position in U.S. dollars.
