Cosentyx (secukinumab), one of Novartis’ top-selling drugs, has failed to show efficacy in a Phase 3 trial of giant cell arteritis, an autoimmune disease affecting the blood vessels. The trial results were announced on 3 July and represent an unusual setback for a drug that has already been approved for seven immune-mediated inflammatory conditions. Cosentyx inhibits interleukin-17A and was first approved in the US in 2015 for plaque psoriasis. The name of the recent trial was GCAptAIN.
