Roivant Sciences, Priovant announce results from Phase 2 study of brepocitinib

Roivant and Priovant announced the Phase 2 study evaluating oral brepocitinib in adult patients with moderate to severe active lupus did not meet its primary endpoint of Systemic Lupus Erythematosus Responder Index change of 4 at Week 52. Priovant plans to disclose the study data at a future date. “We saw some of the highest SRI-4 responder rates ever observed in a lupus study in the active arm of this trial, along with a favorable safety and tolerability profile. Unfortunately, we also saw the highest placebo response rate observed in any significant SLE study, and as such it was not possible to truly assess the impact of the drug, or to establish sufficient differentiation from other therapies in lupus patients. While we do not plan to progress the program in SLE, these results continue to support our view that oral brepocitinib is a highly active agent with a good safety profile, and we remain enthusiastic about brepocitinib’s ability to produce meaningful clinical benefit in non-infectious uveitis and dermatomyositis in Priovant’s ongoing trials, as well as in many other potential indications” said Matt Gline, CEO of Roivant. “Roivant and Priovant would like to extend our gratitude to the patients who participated in this trial, their caregivers, and the trial investigators that enabled this study and these insights.”
