Insights

Ultragenyx shows strong revenue growth while advancing key pipeline assets, though profitability remains a 2027 target.

Ultragenyx delivered $166 million in Q2 revenue, representing 13% year-over-year growth. The company's flagship product Crysvita generated $120 million (72% of total revenue), while Dojolvi contributed $23 million. Despite this growth, the company still posted a $115 million net loss ($1.17 per share), though this represents an improvement from the $132 million loss in Q2 2024.

The quarterly cash burn rate of $108 million remains substantial, leaving $539 million in cash reserves. At the current burn rate, this provides approximately 5 quarters of runway, though management has reaffirmed their path to profitability by 2027 through revenue growth and spending prioritization.

The company's financial guidance remains unchanged, projecting full-year revenue between $640-670 million (14-20% growth over 2024). However, they've indicated that net cash used in operations will modestly increase compared to their previous guidance due to timing delays affecting several programs.

The critical value drivers remain in the pipeline. Two particularly important catalysts are approaching: Phase 3 data for UX143 in osteogenesis imperfecta expected around year-end, and the full enrollment of the Phase 3 study for GTX-102 in Angelman syndrome, which received Breakthrough Therapy Designation from the FDA. The FDA's Complete Response Letter for UX111 (Sanfilippo syndrome) represents a regulatory setback, though management characterizes the issues as "readily addressable" manufacturing concerns rather than clinical efficacy problems.

The 20% revenue growth in the first half compared to 2024 demonstrates commercial momentum, but the pathway to profitability will require both continued top-line expansion and disciplined cost management as multiple late-stage programs advance toward potential commercialization.

Ultragenyx's key pipeline assets reach critical stages with UX143 Phase 3 readouts approaching and GTX-102 earning Breakthrough status.

Ultragenyx's clinical pipeline is reaching several inflection points that could significantly transform the company's trajectory in rare disease therapeutics. The Phase 3 Orbit and Cosmic studies for UX143 in osteogenesis imperfecta (OI) have progressed well, with a Data Monitoring Committee interim analysis confirming an acceptable safety profile. Final analysis data expected around year-end 2025 will be pivotal, as positive results could position UX143 as the first approved therapy specifically targeting bone quality in OI patients.

The GTX-102 program for Angelman syndrome has gained significant momentum with two important developments: FDA Breakthrough Therapy Designation and completion of enrollment in the Phase 3 Aspire study. The Breakthrough designation acknowledges the preliminary evidence showing consistent developmental gains across multiple symptom domains in patients treated for up to 3 years. With 129 patients now enrolled across 28 global sites, the Phase 3 study is well-positioned for its data readout in H2 2026.

The regulatory setback for UX111 in Sanfilippo syndrome represents a delay rather than a program failure. The FDA's Complete Response Letter focused on chemistry, manufacturing, and controls issues rather than clinical efficacy concerns. The agency acknowledged the robustness of the neurodevelopmental outcome data, suggesting the clinical package is compelling despite the manufacturing issues.

The company is also advancing DTX401 for Glycogen Storage Disease Type Ia toward a BLA submission in Q4 2025, supported by strong 96-week data showing substantial reductions in daily cornstarch requirements (60-64%). Meanwhile, enrollment continues in the fourth cohort of the UX701 study for Wilson Disease.

Collectively, these programs represent potential breakthroughs for patients with devastating rare diseases that currently have limited or no treatment options, particularly UX143 for OI and GTX-102 for Angelman syndrome, which could become transformative therapies if their Phase 3 studies succeed.

Recent Updates and Clinical Milestones

UX143 (setrusumab) monoclonal antibody for osteogenesis imperfecta (OI): Final analysis for Phase 3 Orbit and Cosmic studies around the end of 2025

The Phase 3 Orbit and Cosmic studies, which evaluate setrusumab in pediatric and young adult patients with OI, are progressing towards their final analyses around the end of 2025. The randomized, placebo-controlled Phase 3 portion of the Orbit study was evaluated by the Data Monitoring Committee at an interim analysis in July 2025 and they informed the company that UX143 demonstrated an acceptable safety profile and that the study should continue to the final analysis. Conduct of the study is going well and patient safety in the Phase 3 is consistent with the Phase 2.

Data from the Cosmic study were not analyzed at the interim timepoint, consistent with the statistical analysis plan. Study conduct is going well and safety in this younger patient population is consistent with the safety profile in the other studies.

Patients will continue dosing in the ongoing Phase 3 Orbit and Cosmic clinical studies with the final analyses to be conducted after patients have been on therapy for at least 18-months. The threshold for the Phase 3 Orbit final analysis is p<0.04 and for the Phase 3 Cosmic final analysis is p<0.05.

GTX-102 an antisense oligonucleotide for Angelman syndrome: Phase 3 study fully enrolled; Phase 3 data expected in the second half of 2026

In June 2025, Breakthrough Therapy Designation (BTD) was granted by the FDA for GTX-102 as a treatment for Angelman syndrome. The FDA’s decision was based on preliminary clinical evidence including positive data from the Phase 1/2 study in 74 patients (4-17 years of age) with a full maternal UBE3A gene deletion, that showed participants have made consistent developmental gains with rapid, sustained and continuing improvements across multiple symptom domains when treated for up to 3 years. 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.

In July 2025, enrollment of the global Phase 3 Aspire study was completed, ahead of plan due to patient and investigator interest, with 129 patients screened and randomized across 28 global sites. Participants are randomized 1:1 to receive GTX-102 by intrathecal injection via lumbar puncture or to the sham comparator group during the 48-week primary efficacy analysis period. The primary endpoint is improvement in cognition assessed by Bayley-4 cognitive raw score, and the key secondary endpoint (with a 10% allocation of alpha) is the Multi-domain Responder Index (MDRI) across the five domains of cognition, receptive communication, behavior, gross motor function, and sleep. Data from this study are expected in the second half of 2026.

The Phase 2/3 Aurora study, which will evaluate GTX-102 in other Angelman syndrome genotypes and ages, is expected to initiate in the second half of 2025.

UX111 AAV gene therapy for Sanfilippo syndrome type A (MPS IIIA): Working with FDA to resolve observations from Complete Response Letter (CRL)

In July 2025, the FDA issued a CRL for the Biologics License Application (BLA) for UX111 requesting additional information and improvements related to specific aspects of chemistry, manufacturing and controls (CMC) procedures and validation as well as observations from the recently completed manufacturing facility inspections. The company believes the observations are readily addressable and many have been addressed. The company will work with the FDA through a Type A meeting to agree on the planned resolution of the observations. Once agreement on the contents of a filing have been reached, the company expects to resubmit the BLA and anticipates up to a 6-month review period to follow the resubmission.

Clinical review had been ongoing and the FDA has acknowledged that the neurodevelopmental outcome data provided to date are robust and the biomarker data provide additional supportive evidence. The CRL did not note any review issues related to the clinical data package nor clinical inspections and specified that updated clinical data for particular endpoints from the current patients be included in the resubmission.

DTX401 AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa): BLA submission expected in the fourth quarter of 2025

A BLA for DTX401 for the treatment of GSDIa is planned to be submitted in the fourth quarter of 2025. The BLA will include data from the randomized, placebo controlled Phase 3 study and the previously disclosed 96-week data that demonstrated patients had even greater reductions in total daily cornstarch at their last visit compared to baseline in both the ongoing DTX401 group (-60%) and the Crossover Placebo to DTX401 group (-64%) when compared to the 48-week data. It will also include updates to proactively respond to related FDA observations identified in the UX111 CRL in the CMC section and at the company’s gene therapy manufacturing facilities.

UX701 AAV gene therapy for Wilson Disease: Phase 1/2/3 study ongoing; Cohort 4 enrollment ongoing, completion expected in second half of 2025

Enrollment is ongoing in the fourth cohort evaluating a 4.0e13 GC/kg dose in the ongoing, dose-finding, stage of the pivotal Cyprus2+ study of UX701 for the treatment of Wilson disease. The company is on track to enroll five patients in Cohort 4 who will receive immunomodulation therapy with rituximab and tacrolimus, in addition to the prophylactic oral corticosteroid regimen patients in Cohorts 1 through 3 received, prior to being dosed with UX701. Enrollment in Cohort 4 is expected to complete in the second half of 2025.
