Recent Updates and Clinical Milestones

UX143 (setrusumab) monoclonal antibody for Osteogenesis Imperfecta (OI): Phase 3 portion of Orbit study expected to be fully enrolled around the end of the first quarter of 2024
Patients are being dosed in the late-stage clinical trials, Orbit and Cosmic, which are evaluating setrusumab in pediatric and young adult patients with OI. The randomized, placebo-controlled Phase 3 portion of the Orbit study is expected to enroll approximately 150 patients and be fully enrolled around the end of the first quarter of 2024. Additional longer-term Phase 2 safety and efficacy data from the Orbit study are expected in the second half of 2024.

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 age 2 to <5 years. Cosmic is expected to enroll approximately 50 patients or more at more than 20 global sites and is expected to complete enrollment in the first half of 2024.

GTX-102 antisense oligonucleotide for Angelman syndrome: Phase 1/2 fully enrolled; expansion data expected in the first half of 2024
Enrollment in the expansion cohorts was completed in December 2023 with a total of 53 new patients enrolled. A total of 74 patients are enrolled in the Phase 1/2 study including the dose-escalation/extension study patients. The expansion cohorts will evaluate many of the same safety, pharmacokinetic, and efficacy measures as the previously enrolled dose-escalation/extension cohorts plus some new evaluations. The next safety and efficacy update is expected in the first half of 2024 and is planned to include data from at least 20 expansion cohort patients with a minimum of Day 170 data.

In January 2024, GTX-102 was accepted into the Priority Medicines (PRIME) program by the European Medicines Agency (EMA). PRIME is granted by the EMA to medicines that show the potential to benefit patients with unmet needs based on early clinical data. Through PRIME, the EMA offers early and proactive support to optimize development plans and the generation of robust data on a medicine’s benefits and risks, and enables accelerated assessment of medicines applications.

UX701 AAV gene therapy for Wilson disease: Last patient in Cohort 3 dosed; expect interim Stage 1 data in mid-2024
All patients in the three dose-escalation cohorts of Stage 1 have been dosed. During Stage 1, the safety and efficacy of UX701 will be evaluated and a dose will be selected for further evaluation in Stage 2, the pivotal, randomized, placebo-controlled stage of the study. Data from Stage 1 are expected in mid-2024, which will be followed by dose selection and initiation of Stage 2 in the second half of 2024.

UX111 AAV gene therapy for Sanfilippo syndrome (MPS IIIA): Updated data from pivotal Transfer A study presented at WORLDSymposium^TM
New positive data from the ongoing pivotal Transfer A study evaluating the safety and efficacy of UX111 in children with MPS IIIA were presented at the 20th Annual WORLDSymposium™ earlier this month showing that a single infusion of UX111 can substantially correct the underlying metabolic disease and maintain cognitive function in nearly all patients. The presentation also showed that the observed reductions of heparan sulfate exposure in cerebrospinal fluid can predict improved long-term cognitive function in patients with MPS IIIA following treatment with UX111. With these data and other data, discussions are ongoing with the FDA seeking an accelerated review path for UX111.

DTX401 AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa): Dosing in Phase 3 study complete; Phase 3 data readout expected in the first half of 2024
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 safety and efficacy data are expected in the first half of 2024.

DTX301 AAV gene therapy for Ornithine Transcarbamylase (OTC) Deficiency: Phase 3 study dosing patients; expect enrollment to be completed in the first half of 2024
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. Enrollment is currently expected to be completed in the first half of 2024.
