“In 2022, we continued to reach more patients around the world as we successfully commercialized multiple products to treat rare diseases,” said Emil D. Kakkis, M.D., Ph.D., chief executive officer and president of Ultragenyx. “2023 will be a year of meaningful development progress for us as we focus on data generation from two of our key programs, UX143 in osteogenesis imperfecta and GTX-102 in Angelman syndrome, and the continued advancement of our late-stage gene therapy programs.”

Fourth Quarter and Full Year 2022 Selected Financial Data Tables and Financial Results

For the fourth quarter of 2022, Ultragenyx reported $103.3 million in total revenue. Ultragenyx recognized $74.6 million in Crysvita (burosumab) revenue in the Ultragenyx territories¹, which includes $66.9 million in collaboration revenue in the North American profit-share territory and net product sales in other regions of $7.7 million. Total royalty revenue related to European Crysvita sales was $6.1 million. Dojolvi (triheptanoin) revenue in the fourth quarter of 2022 was $16.4 million. Mepsevii (vestronidase alfa) revenue for the fourth quarter of 2022 was $4.8 million. Total revenue for the fourth quarter also includes $1.5 million of revenue related to the collaboration and license agreement with Daiichi Sankyo that was executed in March 2020.

Revenue for the year ended December 31, 2022 was $363.3 million, including $257.7 million in Crysvita revenue in the Ultragenyx territories¹. Crysvita collaboration revenue in the North American profit-share territory was $215.0 million and net Crysvita product sales in other regions were $42.7 million. Total royalty revenue related to European Crysvita royalties was $21.7 million. Dojolvi product revenue for the year ended December 31, 2022 was $55.6 million. Mepsevii product revenue was $20.6 million. For the year ended December 31, 2022, revenue related to our strategic manufacturing partnership with Daiichi Sankyo was $7.7 million.

Recent Updates and 2023 Clinical Milestones

UX143 (setrusumab) monoclonal antibody for Osteogenesis Imperfecta (OI): Phase 2/3 study dosing patients; Phase 2 enrollment complete, data expected in mid-2023
Ultragenyx is currently dosing patients in the Phase 2/3 Orbit study of UX143 in pediatric and adult patients with OI aged five to <26 years. Enrollment in the Phase 2 portion of the study is complete and data are expected in mid-2023. The Phase 2 data are expected to include changes in bone biomarkers response and some data on bone mineral density that will be used to establish the dosing algorithm for the Phase 3 portion of the study. Optimizing the dosing across the age range of the study is intended to support meaningful benefit in the reduction of clinically evident fractures in all age groups studied.

In addition, in the first half of 2023, Ultragenyx intends to initiate a randomized study in OI in children under age five with serious bone disease, comparing bisphosphonates to UX143. Younger pediatric patients with OI often have a much higher fracture rate than other age groups and a greater medical need, driving clinical urgency for better treatment options. Total fractures is expected to be the primary endpoint in the study.

GTX-102 antisense oligonucleotide for Angelman syndrome: Phase 1/2 continues dose exploration
As of January 2023, 23 patients had received loading doses ranging from 2 mg to 10 mg, with maintenance dosing ranging up to 10 mg to 14 mg. Ten patients have had between six and twelve months of exposure to GTX-102 and five patients have been on continuous therapy for more than one year. Based on the current protocols, the dose-finding cohorts in the U.K. and Canada will be followed by two, larger expansion cohorts with approximately 20 patients in each age range. Discussions are currently ongoing with the FDA to harmonize the three regions.

Based on the ongoing observations of encouraging clinical activity in the dose escalation cohorts, screening began for patients in expansion Cohort A (ages 4 to <8 years) and expansion Cohort B (ages 8 to <18 years) in February 2023. Each expansion cohort will enroll approximately 20 patients and will evaluate the same safety, pharmacokinetic, and efficacy measures as the dose escalating cohorts.

There continues to be dose and time dependent clinical activity seen across the study population, including three of the original U.S. patients who have been re-dosed, under the amended or expanded access protocols. The next data update, based on a larger number of patients in the program, is expected later this year.

DTX401 AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa): Enrollment in Phase 3 study complete
The Phase 3 study has a 48-week primary efficacy analysis period, and the company has enrolled approximately 50 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. The last patient has entered the baseline screening phase of the Phase 3 study of DTX401, with Phase 3 data expected in the first half of 2024.

DTX301 AAV gene therapy for Ornithine Transcarbamylase (OTC) Deficiency: Phase 3 study enrolling patients
Ultragenyx has randomized and dosed the first patient in the Phase 3 study with additional patients in the approximate 4- to 8-week baseline screening period. The 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.

UX701 AAV gene therapy for Wilson Disease: Stage 1 of pivotal clinical study dosing patients; expect interim Stage 1 enrollment completion in mid-2023
The company is dosing patients in the first stage of the pivotal UX701 study under a recently amended protocol that removes placebo from the dose finding stage and enrolls five patients per cohort. During this stage of the study, safety and efficacy of up to three dose levels of UX701 will be evaluated and a dose will be selected for further evaluation in Stage 2. Completion of Stage 1 enrollment is expected in mid-2023 with data expected in early 2024 that would include safety and potentially initial signs of clinical activity.

UX111 AAV gene therapy for UX111 for the treatment of Sanfilippo syndrome type (MPS IIIA): Discussions ongoing with FDA to determine a plan to file for accelerated approval
In May 2022, Ultragenyx announced an exclusive license agreement with Abeona Therapeutics for UX111, formerly ABO-102. Under the terms of the agreement, Ultragenyx assumed responsibility for the UX111 program in exchange for Abeona’s right to receive tiered royalties of up to 10% on net sales, and milestone payments upon the attainment of certain commercial revenue milestones.

A meeting with the FDA to discuss a plan to file for accelerated approval is expected to occur in the first half of 2023.

UX053 mRNA for glycogen storage disease type III (GSDIII): Phase 1/2 single ascending dose cohort enrolled; data in 1H23
Dosing in the single ascending dose stage of the Phase 1/2 study of UX053 for the treatment of GSDIII has been completed. Data from this cohort are expected in the first half of 2023. Based on these analyses and other work, we will then review our plans for the next steps in the program.

1: Ultragenyx territories include the collaboration revenue from the North American profit-share territory (U.S. and Canada) and other regions where revenue from product sales is recognized by Ultragenyx (Latin America, Turkey). This excludes the European territory revenue, which is recognized as non-cash royalty revenue since the rights were sold to Royalty Pharma in December 2019.
