It looks like Biogen Inc.’s Nrf2 activator, Skyclarys (omaveloxolone), will maintain its status as the sole therapy approved for treating patients with Friedreich’s ataxia (FA), at least for now. The U.S. FDA asked for another “adequate and well-controlled study” in the complete response letter (CRL) issued to PTC Therapeutics Inc. for 15-lipoxygenase inhibitor vatiquinone.

Manufacturing issues are the latest problem for Ultragenyx Pharmaceutical Inc. to solve after last week’s disappointment in a phase III study to treat brittle bones.

Developing a therapy for an ultra-rare condition has its challenges, including finding enough patients for clinical enrollment and convincing regulatory authorities that limited data prove the candidate is safe and effective. For that reason, Stealth Biotherapeutics Inc. has faced numerous roadblocks getting its mitochondria-targeting elamipretide across the finish line for Barth syndrome, a condition that affects about 230 to 250 males worldwide, including fewer than 150 in the U.S.
Barely a year after the U.S. FDA shackled Abeona Therapeutics Inc.’s cell-based gene therapy with a complete response letter, the agency has approved it for treating a rare and genetic skin disease.
