Efgartigimod leaps hurdle
Efgartigimod, the antibody treatment being developed by argenx SE for a spectrum of autoimmune diseases leapt, over another hurdle on 17 August with news that it had met the primary endpoint in a trial of two rare muscle diseases. The Phase 3 study showed that the antibody fragment, in combination with hyaluronidase enzymes, was able to restore the strength and muscle function in patients with two types of myositis: immune-mediated necrotising myopathy (IMNM) and dermatomyositis (DM). Both diseases cause muscle weakness leading potentially to long-term disability.
