Breakthrough Designation granted for setrusumab (UX143) in osteogenesis imperfecta

DTX401 Phase 3 follow-up data demonstrated higher and faster 62% mean reduction in cornstarch in crossover patients with glycogen storage disease type Ia (GSDIa)

NOVATO, Calif., Nov. 05, 2024 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development and commercialization of novel therapies for serious rare and ultrarare genetic diseases, today reported its financial results for the quarter ended September 30, 2024.

“We continue to see substantial year-over-year revenue growth from our commercial portfolio as we expand geographic access to our medicines. This growth could accelerate with up to three near-term BLA submissions and approvals,” said Emil D. Kakkis, M.D., Ph.D., chief executive officer and president of Ultragenyx. “Today, we are also sharing an important update from our Phase 3 study in GSDIa with substantially larger reductions in cornstarch intake in crossover patients treated with DTX401. As in our Phase 2 patients, we observed that patients and their physicians were far more comfortable with aggressive titration of cornstarch once they were confirmed to be treated with the gene therapy and had direct access to timely glucose readings."

Recent Updates and Clinical Milestones

Dojolvi (triheptanoin) for long-chain fatty acid oxidation disorder (LC-FAOD): Alignment reached on conditional filing requirements with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA)

The Company recently received a positive finalized assessment report with agreement to file for Conditional Early Approval (CEA), from the PMDA, based on the currently available global clinical data. With this feedback, the company expects to file a J-NDA in mid-2025.

UX143 (setrusumab) monoclonal antibody for Osteogenesis Imperfecta (OI): Breakthrough Therapy Designation granted by the U.S. Food and Drug Administration (FDA)

In October 2024, UX143 received Breakthrough Therapy Designation (BTD) from the FDA. This designation is based on preliminary clinical evidence including the positive 14-month results from the Phase 2 portion of the Orbit study, which demonstrated a rapid and clinically meaningful 67% (p=0.0014) decrease in fracture rate in patients. It is also based on data from the completed Phase 2b ASTEROID study. BTD aims to expedite the development and review of drugs that are intended to treat serious or life-threatening diseases and whose preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on one or more clinically significant endpoints over existing therapies.

GTX-102 antisense oligonucleotide for Angelman syndrome: Program update planned for the upcoming Foundation for Angelman Syndrome Therapeutics (FAST) 17^th Annual Global Science Summit and the 53rd Child Neurology Society (CNS) Annual Meeting

Longer-term interim data from the Phase 1/2 study of GTX-102 for the treatment of Angelman syndrome are expected to be presented at the upcoming FAST Science Summit, taking place November 8-9, and the CNS Annual Meeting, taking place November 11-14. Data are expected to include an update on patients from the dose-escalation and expansion cohorts who have been on therapy for at least 338 days and will build on previously presented safety and efficacy data that showed patients demonstrated rapid and clinically meaningful improvements across multiple domains with an acceptable safety profile. 

The company continues to be on track to initiate the pivotal Phase 3 Aspire study by the end of 2024 and the Aurora study in 2025.

UX111 AAV gene therapy for Sanfilippo syndrome type A (MPS IIIA): Successful completion of a pre-BLA meeting with FDA

In October 2024, Ultragenyx participated in a successful pre-BLA meeting with the FDA during which the company aligned on the details of its BLA that is expected to be filed around the end of 2024.

DTX401 AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa): Phase 3 data in crossover patients previously treated with placebo demonstrated 62% mean reduction in cornstarch at Week 30 post-treatment with DTX401 and patients in original treatment arm showed continued reductions in cornstarch

In May 2024, Ultragenyx announced positive topline results from the Phase 3 GlucoGene study for the treatment of patients aged eight years and older. The study achieved its primary endpoint, demonstrating that treatment with DTX401 resulted in a statistically significant and clinically meaningful reduction in daily cornstarch intake compared with placebo at Week 48.

After the 48-week primary efficacy analysis period, crossover patients (previously treated with placebo) were eligible to receive DTX401. Twelve crossover patients have reached Week 30 post-treatment and have had a substantial 62% mean reduction of daily cornstarch at this early timepoint, double the rate of decrease when compared to patients in the original DTX401 treatment arm (n=20) that showed a 41% mean reduction at the end of 48-weeks. Patients were able to titrate cornstarch much more rapidly once they were confirmed to have been treated and had timely direct access to their glucose levels. Patients from the original DTX401 treatment arm who have reached 78 weeks are continuing to reduce their daily cornstarch intake, while maintaining glycemic control. DTX401 has demonstrated a consistent and acceptable safety profile with no new safety concerns identified as of the data cut-off.

These results will be discussed with regulatory authorities to support a BLA submission in mid-2025.

UX701 AAV gene therapy for Wilson disease: Stage 1 update demonstrated clinical activity as well as improvements in copper metabolism

In October 2024, Ultragenyx shared that the Phase 1/2/3 Cyprus2+ study demonstrated clinical activity as well as improvements in copper metabolism for patients treated in Stage 1. Multiple responders completely tapered off their standard-of-care treatment with responses seen in all three dose cohorts. UX701 has been well tolerated, with no unexpected, related treatment-emergent adverse events and no significant immunologic safety events as of the data cut-off.

The company expects to enroll an additional cohort in Stage 1 at a moderately increased dose and with an optimized immunomodulation regimen to enhance the efficiency and efficacy of the gene therapy, with the objective of having the majority of patients come off of standard-of-care treatment before selecting a dose for the randomized placebo-controlled stage of the study.

DTX301 AAV gene therapy for Ornithine Transcarbamylase (OTC) Deficiency: Phase 3 study dosing patients; expect enrollment to be completed in the next few months

Ultragenyx is randomizing and dosing patients in the ongoing Phase 3 study. The pivotal, 64-week study will include up to 50 patients, randomized 1:1 to DTX301 or placebo. The primary endpoints are response as measured by change in 24-hour ammonia levels and removal of ammonia-scavenger medications and protein-restricted diet.
