Press Release: Larimar Therapeutics Completes Rolling BLA Submission Seeking Accelerated Approval of Nomlabofusp for Friedreich’s Ataxia

Today, November 9, 2026, Larimar Therapeutics announced completion of its rolling Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA) seeking accelerated approval of nomlabofusp for the treatment of patients with Friedreich’s ataxia (FA). Nomlabofusp is an investigational protein replacement therapy designed to address the underlying cause of FA, frataxin deficiency, by delivering human frataxin to mitochondria.

Completion of the submission follows previously disclosed FDA feedback on key elements of the BLA and represents a significant milestone for Larimar. Larimar is currently enrolling patients in FORWARD-FA, its global confirmatory Phase 3 study, a double-blind, placebo-controlled study that will evaluate daily subcutaneous use of nomlabofusp over 18 months in ambulatory participants ages 2 to 40 who are new to the drug.
