Ultragenyx Announces Top-Line Results from Phase 3 Study of Ace-ER in GNE Myopathy

Study did not meet its primary endpoint

Novato, CA — August 22, 2017 — Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development of novel products for rare and ultra-rare diseases, today announced that a Phase 3 study evaluating aceneuramic acid extended release (Ace-ER) in patients with GNE Myopathy (GNEM) did not achieve its primary endpoint of demonstrating a statistically significant difference in the upper extremity muscle strength composite score compared to placebo. The study also did not meet its key secondary endpoints. Adverse events were generally balanced between Ace-ER and placebo and safety was consistent with previously released Ace-ER data. Ultragenyx plans to discontinue further clinical development of Ace-ER.

“We are disappointed by these results, as we had hoped that Ace-ER would offer a new option for GNEM patients. We would like to thank the patients, caregivers, and investigators involved in the Ace-ER development program” said Emil D. Kakkis, M.D., Ph.D., Chief Executive Officer and President of Ultragenyx. “This outcome does not affect our overall strategy, as the company moves forward with multiple preclinical and clinical programs and regulatory filings.”

The Phase 3 Ace-ER study enrolled 89 adults with GNEM able to walk > 200 meters in the six minute walk test. Patients were randomized 1:1 to Ace-ER at a dose of 6g/day or placebo for 48 weeks. The study did not meet the primary endpoint of demonstrating a statistically significant improvement in UEC score (+0.74 kg, p=0.5387) for Ace-ER treated patients (n=45, -2.25 kg) compared to placebo (n=43, -2.99 kg) patients for the change from baseline to 48 weeks. There were three pre-specified key secondary endpoints, including the lower extremity muscle strength composite score as measured by hand-held dynamometry (HHD), physical functioning using the Mobility domain of the GNE Myopathy-functional activity scale (GNEM-FAS), and a measure of muscle strength in knee extensors. The study did not meet any of these key secondary endpoints.

Overall, Ace-ER was well tolerated, with slightly more patients experiencing treatment emergent adverse events and related treatment emergent adverse events. There were three serious adverse events including two on Ace-ER and one on placebo, none of which were considered treatment related. There were no discontinuations due to treatment emergent adverse events, and there have been no deaths in the study.

The company plans to terminate the development program based on these results and will work with investigators and patient groups to make available the valuable natural history data and development tools for the development of other therapies. The company will be


 

working with investigators and patients on a reasonable transition plan for patients still on Ace-ER.

Ultragenyx and Kyowa Hakko Kirin Announce Submission of Burosumab’s Biologics License Application in the US

Novato, CA and Tokyo, Japan— August 24, 2017 — Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development of novel products for rare and ultra-rare diseases, and Kyowa Hakko Kirin Co., Ltd. (Kyowa Hakko Kirin) today announced that Ultragenyx has submitted a Biologics License Application (BLA) with the Food and Drug Administration (FDA) for burosumab to treat X-Linked Hypophosphatemia (XLH) in the US. Burosumab has previously received Breakthrough Therapy Designation from the FDA for the treatment of XLH in pediatric patients one year of age and older.

The FDA will evaluate the submission and will decide on whether to accept it within 60 days, at which time the Prescription Drug User Fee Act (PDUFA) action date will be set. 

 

Ultragenyx, Kyowa Hakko Kirin and Kyowa Kirin International PLC., a wholly owned subsidiary of Kyowa Hakko Kirin, have been collaborating in development and commercialization of burosumab globally based on the collaboration and license agreement between Kyowa Hakko Kirin and Ultragenyx.

 

About Burosumab

Burosumab is an investigational recombinant fully human monoclonal IgG 1 antibody, discovered by Kyowa Hakko Kirin, against the phosphaturic hormone fibroblast growth factor 23 (FGF23). FGF23 is a hormone that reduces serum levels of phosphorus and active vitamin D by regulating phosphate excretion and active vitamin D production by the kidney. Burosumab is being developed by Ultragenyx and Kyowa Hakko Kirin to treat XLH and tumor-induced osteomalacia (TIO), diseases characterized by excess levels of FGF23.


 

Phosphate wasting in XLH and TIO is caused by excessive levels and activity of FGF23. Burosumab is designed to bind to and thereby inhibit the biological activity of FGF23. By blocking excess FGF23 in patients with XLH and TIO, burosumab is intended to increase phosphate reabsorption from the kidney and increase the production of vitamin D, which enhances intestinal absorption of phosphate and calcium.

A clinical program studying burosumab in adults and pediatric patients with XLH is ongoing. Burosumab is also being developed for TIO, a disease characterized by typically benign tumors that produce excess levels of FGF23, which can lead to severe osteomalacia, fractures, bone and muscle pain, and muscle weakness.
