argenx announces approval of VYVDURA® (efgartigimod alfa and hyaluronidase-qvfc) injection for subcutaneous use in Japan for generalized myasthenia gravis
argenx SE (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced that Japan’s Ministry of Health, Labour and Welfare (MHLW) approved VYVDURA® (efgartigimod alfa and hyaluronidase-qvfc) injection for subcutaneous (SC) use for the treatment of adult patients with generalized myasthenia gravis (gMG), who do not have sufficient response to steroids or non-steroidal immunosuppressive therapies (ISTs). Following this decision, VYVGART is now approved in Japan for both intravenous (IV) and self-administered SC use.
“Today’s approval of VYVDURA marks a significant milestone for the gMG community in Japan and furthers our commitment to deliver innovative treatments to autoimmune patients globally,” said Hermann Strenger, General Manager, argenx Japan. “Bringing VYVDURA to Japan means there are now two formulations available for gMG patients, including the possibility to self-inject at home, allowing patients and their healthcare providers to choose the best option to meet their treatment needs.”
The approval of VYVDURA is based on positive results from the Phase 3 ADAPT-SC study. ADAPT-SC established the efficacy of VYVDURA by demonstrating a reduction in percent change from baseline in total immunoglobulin G (IgG) levels comparable to VYVGART IV in adult gMG patients. ADAPT-SC was a bridging study to the Phase 3 ADAPT study, which formed the basis for approval of VYVGART in Japan in January 2022.
