Argenx (ARGX) said Wednesday it will proceed with developing its experimental drug, efgartigimod subcutaneous, to treat idiopathic inflammatory myopathies in its ongoing phase 2/3 study.
The decision follows data from phase 2 results that showed a significant treatment effect in the total improvement score at Week 24 and improvements across key measures in patients treated with efgartigimod subcutaneous compared to placebo.
The company said it will continue to enroll patients across each of the three myositis subtypes in the study, including immune-mediated necrotizing myopathy, anti-synthetase syndrome, and dermatomyositis.
