• FDA IND Clearance for UX016

  The U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for UX016, a small molecule prodrug for GNE myopathy (GNEM).

• Externally Funded Program

  The UX016 program is externally funded by a patient group through clinical proof-of-concept, including the upcoming Phase 1/2 study, reducing Ultragenyx's direct R&D expense.

• Phase 1/2 Study Planned

  A first-in-human Phase 1/2 study for UX016, enrolling approximately 24 adults with GNEM, is expected to begin in the second half of 2026 to evaluate safety and efficacy.

This 8-K confirms the FDA's clearance of the Investigational New Drug (IND) application for UX016, a significant step forward for Ultragenyx's pipeline, especially following recent setbacks with other programs as noted in the last 10-K. The external funding for the UX016 program through clinical proof-of-concept reduces the company's financial risk while advancing a potential treatment for GNE myopathy, a rare and debilitating neuromuscular disorder. The planned Phase 1/2 study in the second half of 2026 will evaluate the safety and efficacy of UX016, which is designed to improve drug delivery to muscle compared to prior therapies. This development provides a positive catalyst for the company's drug development efforts.
