Annual Report 2022

Annual Report 2022

2022 In Brief

In 2022, we executed on our global launch of VYVGART® (efgartigimod alfa) (VYVGART) our first-in-class neonatal Fc receptor (FcRn) blocker, which is now approved in the U.S., Japan and Europe. There are now over 3,000 people globally living with gMG who are on VYVGART.

gMG is just the beginning and efgartigimod is now being evaluated in ten autoimmune indications with three more to start in 2023. We announced positive Phase 3 data from ADAPT-SC evaluating subcutaneous (SC) efgartigimod in gMG and also from ADVANCE evaluating VYGART (intravenous (IV)) in ITP. We are well on our way to achieve our ‘argenx 2025’ vision of efgartigimod either being commercially available or in clinical development in fifteen indications by 2025.

We are advancing a pipeline of differentiated immunology assets across four commercial franchises including neurology, hematology/rheumatology, dermatology and nephrology. Our wholly-owned pipeline currently consists of efgartigimod, ARGX-117 targeting component 2 (C2) and ARGX-119 targeting muscle-specific kinase (MuSK). Our core mission is innovation, and we continue to invest in our immunology innovation program (IIP) from which we drive pipeline expansion by collaborating with leading disease biologists who are researching first-in-class disease targets or pathways. We believe that our IIP has a track record of success and eight programs have demonstrated human proof-of-concept since our inception.

The infinity sign symbolizes process of our commitment that every year we try to devlop best solutions for our patients and moves us forward

Global Efgartigimod Launch

Generated global net product VYVGART revenue of $400.7 million in 2022.

VYVGART was approved for the treatment of gMG in the U.S., Japan and Europe:

  • On December 17, 2021, the U.S. Food and Drug Administration (FDA) approved VYVGART for the treatment of gMG in adult patients who are anti-acetylcholine receptor antibody positive (AChR.AB+). The U.S. commercial launch was initiated in January 2022.
  • On January 20, 2022, Japan’s Ministry of Health, Labour and Welfare (MHLW) approved VYVGART (efgartigimod alfa) for the treatment of adult patients with gMG who do not have sufficient response to steroids or non-steroidal immunosuppressive therapies (ISTs). The Japan commercial launch was initiated in May 2022.
  • On August 11, 2022, the EU Commission granted marketing authorization for VYVGART (efgartigimod alfa-fcab) as an add-on to standard therapy for the treatment of adult patients with gMG who are AChR-AB+. The approval is applicable in all 27 European Union (EU) Member States, Iceland, Norway and Liechtenstein. The commercial launch in Germany was initiated in September 2022.

In addition, in 2022, we made the following progress towards our global launch of VYVGART:

  • argenx Canada was established in February 2022 in preparation for a potential Health Canada approval, expected in the third quarter of 2023, and, if granted, commercial launch in Canada.
  • argenx UK Ltd. was established in August 2022 in preparation for launch in the United Kingdom (UK).
  • argenx Netherlands Services B.V. was established in September 2022 in preparation for launch in the Netherlands.
  • argenx Italy S.r.l. incorporated under the laws of Italy, having its registered office in Milan, Italy and its address at Largo Francesco Richini 6, 20122 Milan, Italy.
  • Zai Lab Ltd (Zai Lab) filed for approval of efgartigimod in the People’s Republic of China (PRC) in the second quarter of 2022. The approval decision is expected in 2023.
  • Medison Pharma Ltd (Medison) filed for approval of efgartigimod in Israel in the second quarter of 2022. The approval decision expected in 2023.
  • Additional distribution partnership agreements for other territories were announced in 2022 to further expand global patient reach. For example, we entered into VYVGART commercial and distribution agreements with Medison in Central and Eastern Europe and with Genpharm Services FZ-LLC (Genpharm) for the Gulf Cooperation Council, comprising Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, Bahrain and Oman (collectively, the GCC).
  • Expanded large-scale manufacturing capabilities and capacity through collaboration with FUJIFILM Diosynth Biotechnologies Denmark ApS (Fujifilm) based in Hillerød, Denmark, to provide large-scale drug substance manufacturing of efgartigimod (in addition to Lonza Sales AG (Lonza)).

Pipeline of Differentiated Antibody Candidates

Click to explore


Efgartigimod is our first-in-class neonatal FcRn blocker. We expect our leadership in FcRn blockade to expand to include thirteen autoimmune indications in the pipeline by the end of 2023, including in our commercial franchises listed below:

ARGX-117 (C2 inhibitor):

ARDA: Phase 2 proof-of-concept clinical trial of ARGX-117 in multifocal motor neuropathy (MMN) ongoing with interim results expected in mid-2023.

Phase 2 proof-of-concept clinical trial to start in delayed graft function (DGF) in the second half of 2023.

DM was announced as the third indication for ARGX-117.

ARGX-119 (muscle-specific tyrosine kinase (MuSK) agonist):

Phase 1 dose-escalation trials in healthy volunteers started in the first quarter of 2023 with subsequent Phase 1b clinical trial to assess early signal detection in patients.

Leo Pharma

LEO Pharma exercised it’s exclusive, worldwide option to ARGX-112 targeting IL22 receptor, which triggered a €5.0 million payment to us.

Creation of OncoVerity, Inc. (OncoVerity):

argenx, the University of Colorado Anschutz Medical Campus and the University of Colorado Health (UCHealth) created an asset-centric spin-off, OncoVerity, focused on optimizing and advancing the development of cusatuzumab, an anti-CD70 antibody, in acute myeloid leukemia (AML). OncoVerity is an entity of co-creation, combining the extensive translational biology insights from Dr. Clayton Smith, M.D. from the University of Colorado with the experience from argenx on the CD70/CD27 pathway. OncoVerity is the fourth spin-off company from our IIP.
