Second Quarter 2022 Revenue and Selected Financial Data Tables

Corporate and Program Updates
Partial sale of North America Crysvita royalty
In July 2022, we sold 30% of our royalty interest in Crysvita, in the profit-share territory, to OMERS for $500.0 million, beginning in April 2023. Total payments are capped at $725.0 million, or 1.45x the purchase price, after which payments to OMERS will cease and Ultragenyx will retain the full value of the royalty.

GTX-102 for Angelman Syndrome

In July 2022, we exercised our option to acquire GeneTx and closed on the acquisition for $75.0 million plus future milestone and royalty payments. Additional milestones include $30.0 million upon achievement of the earlier of a Phase 3 clinical study start or product approvals in Canada and the U.K. We will also pay tiered royalties ranging from a mid-single to low double-digit percentage based on worldwide annual net sales.

In July 2022, we also provided an interim data and program update on patients treated in Canada and the U.K. and the U.S. under each region’s amended protocol for the Phase 1/2 study. Further details from this release can be found on the Company website.

We currently expect to provide a program update after we have determined an optimal dose and have gathered substantial data from the expansion cohorts.

UX143 (setrusumab) for Osteogenesis Imperfecta (OI)
Ultragenyx is dosing patients in the seamless Phase 2/3 Orbit study of UX143 in pediatric and adult patients with OI ages five to <26 years. A dosing update on the Phase 2 portion of the Orbit study and transition to Phase 3 is expected in the second half of 2022.

In addition, Ultragenyx intends to initiate an additional study in children with OI under age 5 years in the second half of 2022 and will continue to follow adult patients who were previously treated in the ASTEROID study, a Phase 2b study conducted by our partner Mereo.

UX111 for Sanfilippo syndrome type A (MPS IIIA)

Ultragenyx entered into an exclusive license agreement from Abeona Therapeutics for UX111 (formerly ABO-102). Under the terms of the agreement, we assumed responsibility for the UX111 program and in return Abeona is eligible to receive tiered royalties of up to 10% on net sales and commercial milestone payments following regulatory approval.

Interim results from the pivotal Transpher A clinical study were presented at the American Society of Gene & Cell Therapy (ASGCT) 2022 Annual Meeting by Abeona. Additional details on this data can be found on the Company website.

DTX401 for Glycogen Storage Disease Type Ia (GSDIa): Phase 3 study dosing patients
Longer-term Phase 1/2 data were presented at ASGCT 2022 Annual Meeting demonstrating a durable response from all 12 patients lasting up to more than 3.5 years following treatment with DTX401.

Dosing and enrollment of the Phase 3 study of DTX401 is ongoing. The Phase 3 study has a 48-week primary efficacy analysis period and the company plans to enroll 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.

UX701 for Wilson Disease: Stage 1 of pivotal clinical study dosing patients
The company is dosing patients in the first stage of the Cyprus2+ study of UX701. 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. In Stage 2, a new cohort of patients will be randomized 2:1 to receive the selected dose of UX701 or placebo. The primary efficacy endpoints are change in 24-hour urinary copper concentration and percent reduction in standard of care medication by Week 52.

DTX301 for Ornithine Transcarbamylase (OTC) Deficiency: Phase 3 study expected to initiate in second half of 2022
Longer-term Phase 1/2 data were presented at the ASGCT 2022 Annual Meeting showing a response from four out of five patients at the Phase 3 dose and a total of seven responders among the 11 patients enrolled in the study. This response included durable metabolic control lasting up to more than four years following treatment with DTX301 in patients with OTC deficiency.

Ultragenyx expects to initiate the Phase 3 study of DTX301 in patients with OTC in the second half of 2022. 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.

UX053 for Glycogen Storage Disease Type III (GSDIII) Debrancher Deficiency: Phase 1/2 study currently dosing patients; preliminary data from first part of study and initiation of second part of study anticipated in second half of 2022
Ultragenyx is dosing patients in the two-part Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of UX053 in adults age 18 years and older with GSDIII. Part 1 of the study is open label with single-ascending doses. Part 2 is double-blind and will evaluate repeat doses at escalating levels. We currently expect preliminary data from Part 1 of the study and to initiate Part 2 of the study in the second half of 2022.

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 are 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.
