Material Changes and Operational Updates
Revenue Impact: Crysvita revenue in the United States was impacted by a decrease in channel inventory due to the transition of North America commercialization responsibilities from Ultragenyx to Kyowa Kirin Co., Ltd. (KKC). This one-time change involved a shift from Ultragenyx-labeled product to KKC-labeled product. Management expects channel inventories to normalize by year-end.
Clinical Data Highlights:
- UX143 (setrusumab) for Osteogenesis Imperfecta (OI): Interim Phase 2 data from the Orbit study showed a 67% reduction in annualized fracture rates (from 0.72 to 0.00) after at least six months of treatment. Lumbar spine bone mineral density (BMD) increased by 13% to 16% depending on dosage. No treatment-related serious adverse events were observed.
- GTX-102 for Angelman Syndrome (AS): Extension cohort data showed clinically meaningful improvements in multiple domains. Patients who stopped and restarted treatment reacquired developmental skills. No additional treatment-related serious adverse events have been reported since November 2022.
- UX701 for Wilson Disease: In the lowest-dose cohort, four of five patients showed improvements allowing for tapering of standard of care. Two patients are now completely off standard therapy. No treatment-related serious adverse events were reported.
Guidance, Outlook, and Risks
Future Data Expectations:
- UX143: Updated Phase 2 data planned for next year.
