Breakthrough Therapy designation based on interim clinical data from Phase I/II trials showing clinically meaningful improvements in cardiac biomarkers and functional measures
LX2006 also selected for FDA Chemistry, Manufacturing, and Controls Development and Readiness Pilot (CDRP) program, created to facilitate CMC registrational readiness and support faster patient access
NEW YORK, July 07, 2025 (GLOBE NEWSWIRE) -- Lexeo Therapeutics, Inc. (Nasdaq: LXEO), a clinical stage genetic medicine company dedicated to pioneering novel treatments for cardiovascular diseases, today announced that the U.S. Food and Drug administration (FDA) has granted Breakthrough Therapy designation to LX2006 based on clinical evidence generated on both cardiac and neurologic measures of Friedreich ataxia (FA). LX2006 has also been selected to participate in the FDA Chemistry, Manufacturing, and Controls (CMC) Development and Readiness Pilot (CDRP) program, intended to enable earlier patient access to therapies with expedited clinical development timelines.
“Receiving Breakthrough Therapy designation is a significant milestone, highlighting the potential of LX2006 and the strength of clinical evidence generated to date,” said Dr. Sandi See Tai, Chief Development Officer of Lexeo Therapeutics. “We are highly encouraged by the impact of LX2006 on key measures of cardiac health, especially given the lack of treatments for FA cardiomyopathy today, which is the leading cause of death in FA. We are also optimistic about the improvements we have observed in functional measures of FA more broadly, and we look forward to a continued partnership with the FDA through the Breakthrough Therapy designation and the CDRP program as we work to bring this potential treatment to patients as quickly as possible.”
The FDA decision was based on interim clinical data demonstrating that treatment with LX2006 was associated with clinically significant improvements in cardiac biomarkers and in cardiac and neurologic functional measures, with increased frataxin expression observed in all participants with cardiac biopsies at three months post treatment. To date, 17 participants have been treated across two trials: the Lexeo-sponsored SUNRISE-FA Phase 1/2 clinical trial ( NCT05445323 ) and the Weill Cornell Medicine investigator-initiated Phase 1A trial ( NCT05302271 ). Lexeo is currently enrolling a prospective natural history study, CLARITY-FA, which will serve as a concurrent external control arm for the registrational study. The Company expects to initiate the registrational study by early 2026 and is actively working with FDA to finalize the statistical analysis plan (SAP).
Breakthrough Therapy designation is intended to accelerate the development and review of investigational therapies that aim to treat serious or life-threatening diseases and where preliminary clinical evidence indicates that the therapy may demonstrate substantial improvement over available alternatives. This designation is in addition to Regenerative Medicine Advanced Therapy (RMAT) designation, Orphan Drug designation and Fast Track designation, all previously granted to LX2006 by the FDA. The CDRP program was created by the FDA to facilitate expedited CMC development of investigational therapies with expedited clinical development timeframes. This program increases communication between FDA and sponsors on CMC development specifically, with the goal of enabling earlier patient access to promising therapies in areas of high unmet need.
