FDA Confirms That Use of mFARS as Primary Endpoint in Part 2 of the MOXIe Trial Can Support Approval of Omaveloxolone in Friedreich’s Ataxia

IRVING, Texas, Aug. 14, 2017 (GLOBE NEWSWIRE) -- Reata Pharmaceuticals, Inc. (Nasdaq:RETA) (“Reata” or the “Company”), a clinical-stage biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) confirmed that the modified Friedreich’s Ataxia Rating Scale (mFARS) is an acceptable primary endpoint for Part 2 of the MOXIe trial for omaveloxolone in Friedreich’s ataxia (FA).

The FDA communication was made in response to the Company’s request that the FDA confirm its prior guidance that, depending on the MOXIe trial results, mFARS could be appropriate to support approval of omaveloxolone for FA under Subpart H.  In the recent communication, FDA indicated that it may consider either accelerated or full approval based on the overall results of the trial and strength of the data.  FDA also recommended that the Company extend the treatment duration for Part 2 of the study and add a straightforward patient-reported or performance-based outcome endpoint to the study.

“This communication from the FDA confirms our view that mFARS could support approval in Friedreich’s ataxia, and we believe that it leaves open an opportunity for full approval if the trial produces robust clinical results,” said Colin Meyer, Chief Medical Officer of Reata.  “We remain committed to rapidly advancing omaveloxolone so that it could be the first approved treatment for this serious, debilitating, and life-shortening condition.”

Part 2 of the MOXIe trial will be a double-blind, randomized, placebo-controlled, multi-center, international trial designed to evaluate the safety, tolerability, and efficacy of omaveloxolone in patients with FA.  The trial will enroll approximately 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.  Additional endpoints will include the change from baseline in peak work during maximal exercise testing, Patient Global Impression of Change, and Clinical Global Impression of Change.  The Company has initiated screening patients for Part 2 of MOXIe and plans to randomize the first patient during the second half of 2017.

About Friedreich's Ataxia

FA is a rare, degenerative, life-shortening neuro-muscular disorder that affects children and adults and involves the loss of strength and coordination usually leading to wheelchair use; diminished vision, hearing and speech; scoliosis (curvature of the spine); increased risk of diabetes; and a life-threatening heart condition.  Currently, there are no FDA-approved treatments for FA.
