FDA Allows Modified Rating Scale for Omaveloxolone Trial
FDA has told Reata Pharmaceuticals that its modified Friedreich’s Ataxia Rating Scale (mFARS) is an acceptable primary endpoint for Part 2 of the company’s MOXIe trial for omaveloxolone in Friedreich’s ataxia (FA). The rare, degenerative, life-shortening neuro-muscular disorder affects children and adults and involves the loss of strength and coordination usually leading to wheelchair use; diminished vision, hearing and speech; scoliosis; increased risk of diabetes and a life-threatening heart condition. Currently, there are no FDA-approved treatments for FA.
According to the company, FDA’s recent communication indicated that it may consider either accelerated or full approval based on the overall results of the trial and strength of the data. The agency also recommended that it extend the treatment duration for Part 2 of the study and add a straightforward patient-reported or performance-based outcome endpoint to the study.
MOXIe Part 2 is a double-blind, randomized, placebo-controlled, multi-center, international trial designed to evaluate the safety, tolerability, and efficacy of omaveloxolone in patients with FA. It is intended to enroll about 100 FA patients randomized evenly to either 150 mg of omaveloxolone or placebo. The primary endpoint of the trial will be the change from baseline in mFARS of omaveloxolone compared to placebo at 48 weeks.
