"In the second quarter, our global commercial efforts have resulted in continued meaningful growth of Crysvita, Dojolvi and Mepsevii revenue, including in our key territories outside of the U.S.," said Emil D. Kakkis, M.D., Ph.D., chief executive officer and president of Ultragenyx. "At the same time, we have continued to advance key clinical programs for osteogenesis imperfecta (OI), Angelman syndrome and Wilson disease, which are expected to generate a number of data catalysts over the next few quarters."

Recent Updates and Clinical Milestones
UX143 (setrusumab) monoclonal antibody for Osteogenesis Imperfecta (OI): Two Phase 3 studies enrolling, additional Phase 2 data expected in mid-October
Positive data from the dose-selection Phase 2 portion of the Phase 2/3 Orbit study were announced in June 2023 and showed that setrusumab rapidly induced bone production in patients with OI. Setrusumab treatment induced statistically significant increases in levels of serum P1NP, a sensitive marker of bone formation, and a substantial and significant improvement in bone mineral density (BMD) by three months. Serum P1NP levels through at least 1 month of treatment were available from all 24 patients enrolled in Orbit and demonstrated that treatment with setrusumab significantly increased serum P1NP, peaking at one to two weeks and again, as expected, after the 2-month dosing timepoint. The Phase 2 Orbit data demonstrated meaningful response in serum P1NP and BMD across both cohorts, with the majority of the effect observed at 20 mg/kg when compared to the 40 mg/kg cohort.
The large increase in BMD observed in the Orbit patient population over the first 3 months was consistent with the rapid increase in serum P1NP levels and was similar to results that took 1 year to achieve in the ASTEROID study in adult OI patients. Treatment with setrusumab for 3 months resulted in an increase in lumbar spine BMD from baseline of 9.4% at 20 mg/kg (n=10), which represents a substantial mean change in Z-score of +0.65 from -2.12 (n=11) at baseline. Treatment with 40 mg/kg (n=7) resulted in a 9.8% BMD increase. Patients on placebo at the 3-month timepoint (n=2) showed no significant change in BMD or change in lumbar spine Z-score.
As of the data cut-off, there had been no treatment-related serious adverse events observed in the study. Reported adverse events were generally consistent with those observed in the ASTEROID study and included infusion associated events, headache and sinusitis. There were no reported hypersensitivity reactions related to setrusumab. There were no safety-related differences observed between dosing groups or age groups.
In July we announced, the first patients were dosed in both of the late-stage clinical trials, Orbit and Cosmic, which evaluate setrusumab in pediatric and young adult patients with OI. Orbit is expected to enroll approximately 195 patients at more than 40 sites across 12 countries. The Phase 3 Cosmic study is an active-controlled study evaluating the effect of setrusumab compared to intravenous bisphosphonate (IV-BP) therapy on annualized total fracture rate in patients aged 2 to <5 years. Cosmic is expected to enroll approximately 65 patients at more than 20 global sites.
Additional data, including fracture frequency information, from the Phase 2 portion of the Orbit study are expected to be shared at an Analyst Day planned for mid-October.
GTX-102 antisense oligonucleotide for Angelman syndrome: Phase 1/2 expansion cohorts enrolling; program update planned for mid-October 2023
In May 2023, the company announced that the FDA reviewed and agreed to a protocol amendment to the Phase 1/2 study of GTX-102 in pediatric patients with Angelman syndrome that enables the harmonization of dose ranges in the U.S. with those being used in ex-U.S. cohorts of the study. The Phase 1/2, open-label, dose-escalating study is evaluating the safety and tolerability of GTX-102 in pediatric patients with Angelman syndrome with a genetically confirmed diagnosis of full maternal UBE3A gene deletion. The study is looking to verify the GTX-102 dose range and treatment regimen that will be used in the Phase 3 program.
As of August 3, 2023, 19 patients have had more than 12 months of exposure to GTX-102, with the longest approaching two years. The dose escalation phase of this study was completed earlier in the year and dosing in the expansion cohorts is ongoing. As of the date of this release, patients from the dose escalation cohorts continue to exhibit encouraging dose and time-dependent clinical activity following longer-term treatment and maintenance dosing. No additional treatment-related serious adverse events or lower extremity weakness adverse events have occurred since the prior update in January 2023.
Globally, sites are enrolling patients in the expansion cohorts and will evaluate the same safety, pharmacokinetic, and efficacy measures as the dose escalating cohorts. Enrollment has accelerated in the last two months as additional sites, including the U.S., have been activated and there are currently more than 20 patients enrolled at sites around the world. No lower extremity weakness safety events have been observed in patients in the expansion cohorts to date.
An interim program update is expected at an Analyst Day in mid-October 2023. In the first half of 2024, the company expects to share data from the dose expansion cohorts on at least 20 patients who have been therapy for at least 6 months, which is expected to provide a meaningful comparison with natural history in this disease.
UX701 AAV gene therapy for Wilson Disease: Stage 1 of pivotal clinical study dosing patients; expect Stage 1 enrollment completion around the end of the year
Dosing in Stage 1 of the pivotal study is ongoing and is expected to enroll five patients per escalating dose cohort. In July 2023, the data safety monitoring board reviewed safety data from Cohort 1 and recommended escalating to the second dose level (1.0 x 10^13 GC/kg dose). Dosing in Cohort 2 has begun and Stage 1 is on track to complete enrollment around the end of the year. Interim Stage 1 data is expected in the first half of 2024 that would include safety and potentially initial signs of clinical activity.
DTX401 AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa): Dosing in Phase 3 study complete
In May 2023, Ultragenyx announced the last patient had been dosed in the Phase 3 study. The 48-week study has fully enrolled patients eight years of age and older, randomized 1:1 to DTX401 or placebo. The primary endpoint is the reduction in oral glucose replacement with cornstarch while maintaining glucose control. Phase 3 data are expected in the first half of 2024.
DTX301 AAV gene therapy for Ornithine Transcarbamylase (OTC) Deficiency: Phase 3 study dosing patients
Ultragenyx is randomizing and dosing patients in the ongoing Phase 3 study. The pivotal, 64-week study will include approximately 50 patients, randomized 1:1 to DTX301 or placebo. The primary endpoints are response as measured by removal of ammonia-scavenger medications and protein-restricted diet and change in 24-hour ammonia levels.
Analyst Day planned for mid-October
The company intends to host an Analyst Day in mid-October to highlight additional Phase 2 Orbit clinical data, including fracture frequency information in patients with OI, and provide program updates on the pipeline, including GTX-102 for Angelman syndrome.
