The Food and Drug Administration approved two new indications for the interleukin-17A inhibitor secukinumab (Cosentyx) – psoriatic arthritis in adults and ankylosing spondylitis in adults – on Jan. 15. These join the approval for moderate to severe plaque psoriasis in adults it received in January 2015, according to an announcement from the drug’s manufacturer, Novartis.
The approvals are based on the efficacy and safety outcomes from four placebo-controlled, phase III studies, which included more than 1,500 adult patients with ankylosing spondylitis (AS) or psoriatic arthritis (PsA) who were biologic treatment naive or had an inadequate response or were intolerant to anti-TNF agents.
Pivotal phase III studies in the secukinumab clinical trial program, which provided key data for the submission, were MEASURE 1 and MEASURE 2 involving 590 patients with AS, and FUTURE 1 and FUTURE 2 involving 1,003 patients with PsA. Novartis continues to investigate the fully human monoclonal antibody against IL-17A for its potential in preventing radiographic progression of spinal and joint structural damage in AS and PsA patients, respectively.
The European Medicines Agency approved secukinumab for PsA and AS in November 2015.
