Positive Proof-of-Concept Data for Efgartigimod in Pemphigus Vulgaris

23 patients were evaluated for efficacy in an adaptive Phase 2 trial aiming to establish optimal treatment regimen

argenx, a clinical-stage biotechnology company developing a deep pipeline of differentiated antibody-based therapies for the treatment of severe autoimmune diseases and cancer, released a strategic outlook for 2020 outlining key priorities for its broad pipeline and path towards achieving its ‘argenx 2021’ integrated commercial vision.

We begin 2020 in an exciting position, having met all our objectives for our clinical programs. This includes the completion of enrollment of our Phase 3 ADAPT trial of efgartigimod in gMG, the launch of key efgartigimod clinical trials in ITP and CIDP, and the initiation of cusatuzumab clinical trials in two AML settings with Janssen. In addition, we’re announcing today positive proof-of-concept data for efgartigimod in PV, our third ‘beachhead’ indication, further demonstrating our initial development strategy of targeting pathogenic autoantibodies and creating commercial opportunities in several therapeutic areas. Looking forward to the remainder of 2020, we plan up to five registrational efgartigimod trials and further expansion of the cusatuzumab global development plan with Janssen,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx.

Most importantly, we are continuing to execute on the ‘argenx 2021’ vision to become a global, integrated immunology company with our first launch of efgartigimod in gMG expected in 2021. At the core of this growth strategy is a commitment to expanding our early-stage pipeline with immunology breakthroughs and advancing our late-stage candidates while extending our reach to bring first-in-class medicines to patients,” continued Mr. Van Hauwermeiren.

argenx 2021 Vision

argenx continues to execute on its plan to become a fully integrated immunology company through its “argenx 2021” vision, including building two initial commercial franchises in neuromuscular indications and hematology/oncology and expanding its global presence encompassing Boston, Ghent and Tokyo. As part of this vision, argenx highlights:

Leadership in FcRn and its therapeutic immunology potential:

  • On track to launch first FcRn antagonist with efgartigimod in generalized myasthenia gravis (gMG) in 2021
  • Up to five registrational trials expected to be ongoing in 2020 across four targeted indications (gMG, immune thrombocytopenia (ITP), chronic inflammatory demyelinating polyneuropathy (CIDP) and pemphigus vulgaris (PV))
  • Fifth efgartigimod indication expected to be announced in 2020
  • Further research underway exploring therapeutic potential of FcRn modulation
