argenx to Present New Data from Generalized Myasthenia Gravis Program at 2022 American Academy of Neurology Annual Meeting

Regulatory News:

argenx SE (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced that interim data will be presented from ADAPT+ at the American Academy of Neurology (AAN) Annual Meeting in Seattle, WA, April 2-7. ADAPT+ is the global Phase 3 open-label extension study evaluating long-term efficacy, safety and tolerability of VYVGART (efgartigimod alfa-fcab) in adult patients with generalized myasthenia gravis (gMG).

Additional presentations at AAN will include a review of baseline characteristics from the Company’s pre-approval access program for VYVGART, as well as data on the treatment burden of gMG from a cross-sectional study of 152 U.S. adults with a self-reported gMG diagnosis.

“We are thrilled that our ADAPT+ study has been selected for an oral presentation at this important neurology forum, and hope these exciting data will advance healthcare providers’ understanding of long-term therapeutic outcomes with VYVGART as they continue to manage their gMG patients,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx. “We remain as committed as ever to the gMG community, and look toward to offering deeper insight into the patient experience so we may best address their unmet needs and seek to alleviate the burden of this complex, debilitating disease.”
