Program Updates and Upcoming Milestones

Dojolvi for Long-Chain Fatty Acid Oxidation Disorders (LC-FAOD): Launched on July 22, 2020

• The U.S. FDA approved Dojolvi for the treatment of pediatric and adult patients for all forms of LC-FAOD with a molecularly-confirmed diagnosis. Dojolvi is the first FDA-approved therapy for these lifelong and life-threatening genetic disorders and is now available to patients in the U.S.
• Dojolvi has been submitted for approval with ANVISA in Brazil and has been submitted to Health Canada after being granted priority review. Discussions with EU regulators are ongoing. Requests for named patient access will continue to be supported during the ongoing discussions and review in these countries.

GTX-102 for Angelman Syndrome (AS) Conducted by Partner, GeneTx: Positive interim Phase 1/2 data demonstrating substantial improvements in five out of five patients treated

• Preliminary results from the first five patients treated indicate substantial improvements in all patients in at least two disease domains including communication, behavior, sleep, gross motor function, and fine motor function as measured by the Clinical Global Impression of Improvement Scale for Angelman Syndrome.
• After reaching substantially higher doses as planned per protocol, all five patients experienced a serious adverse event (SAE) of lower extremity weakness believed to be related to local inflammation due to GTX-102. Following these events, the companies paused enrollment and dosing. These serious events were assessed as mild or moderate in severity. Four out of five patients have fully recovered with the fifth nearly fully recovered.
• The study protocol will be amended to reduce the dose-level range and modify the administration process, which is expected to reduce further drug-related SAEs. The companies will obtain agreement on these modifications with the US FDA prior to resuming enrollment and dosing.
  

DTX301 for Ornithine Transcarbamylase (OTC) Deficiency: Prophylactic steroid cohort is ongoing

• A fourth cohort of three patients at the same cohort 3 dose of 1.0 × 10^13 GC/kg is ongoing using prophylactic steroids. Data from this cohort are expected by the end of 2020. Phase 3 initiation is expected in 2021.
  

DTX401 for Glycogen Storage Disease Type Ia (GSDIa): Prophylactic steroid cohort has been added, no impact to timing of Phase 3 study

• A fourth cohort of three patients is ongoing at 6.0 x 10^12 GC/kg, the same dose as cohorts two and three, with a prophylactic steroid regimen. Data from this cohort are not expected to impact the timing of a potential Phase 3 study. Phase 3 initiation is expected in the first half of 2021.
  

Crysvita for X-Linked Hypophosphatemia (XLH): Approved by European Commission (EC) for treatment of XLH in older adolescents and adults

• The European Commission (EC) approved Crysvita for the treatment of XLH in older adolescents and adults. This expanded approval adds to the prior indication, which included children and adolescents with growing skeletons, to now include adolescents with radiographic evidence of bone disease, regardless of growth status, as well as adults with XLH are now also eligible for treatment with Crysvita.
  

Crysvita for Tumor-Induced Osteomalacia (TIO): Launched in the United States

• The US FDA approved a second indication for Crysvita in June 2020. Crysvita is now available for the treatment of fibroblast growth factor 23 (FGF23)-related hypophosphatemia in TIO associated with phosphaturic mesenchymal tumors that cannot be curatively resected or localized in adults and pediatric patients 2 years of age and older.
  

Business Development Update

Pre-clinical Gene Therapy: Strategic Collaboration with Solid Biosciences to Develop and Commercialize New Gene Therapies for Duchenne Muscular Dystrophy

• Strategic collaboration combines Solid's differentiated microdystrophin construct and Ultragenyx's HeLa PCL manufacturing platform for use with AAV8 and variants. Under the terms of the collaboration, Ultragenyx was granted an exclusive license for the use of Solid's proprietary microdystrophin construct with AAV8 and variants. Ultragenyx has made a $40 million investment in Solid and has agreed to pay up to $255 million in cumulative milestone payments per product upon achievement of specified milestone events, and tiered royalties on worldwide net sales at low double digit to mid-teens percentages.
