Ultragenyx Pharmaceutical (NASDAQ: RARE) has received a Complete Response Letter (CRL) from the FDA regarding its Biologics License Application (BLA) for UX111, a gene therapy treatment for Sanfilippo syndrome type A. The FDA cited specific chemistry, manufacturing and controls (CMC) related observations that require resolution.
While the FDA acknowledged the robustness of clinical data and supportive biomarker evidence, this delay pushes the potential approval timeline to 2026. The company believes the CMC observations are addressable and primarily relate to facilities and processes, not product quality. After resolving these issues, Ultragenyx plans to resubmit the BLA, which will be followed by an estimated 6-month review period.
