Reata NDA for Treating Friedreich’s Ataxia
FDA has accepted for priority review a Reata Pharmaceuticals NDA for omaveloxolone for treating patients with Friedreich’s ataxia. The submission is based on data from the MOXIe Part 2 trial and additional supporting data from the MOXIe Part 1 and MOXIe Extension trials, according to the company. The agency has set a 11/30 user fee review action target date.
Friedreich’s ataxia is a rare, genetic, life-shortening, debilitating, and degenerative neuromuscular disorder “typically caused by a trinucleotide repeat expansion in the first intron of the frataxin gene, which encodes the mitochondrial protein frataxin,” the company says. These expansions can lead to impaired transcription and reduced frataxin expression, which can result in mitochondrial iron overload and poor cellular iron regulation, it says. Patients with Friedreich’s ataxia typically experience symptoms in childhood, including loss of coordination, muscle weakness, and fatigue that commonly results in the need for a wheelchair.
Reata describes omaveloxolone as an investigational, oral, once-daily activator of Nrf2, a transcription factor that “induces molecular pathways that promote the resolution of inflammation by restoring mitochondrial function, reducing oxidative stress, and inhibiting pro-inflammatory signaling.”
