Second Quarter 2016 Financial Results

For the second quarter of 2016, Ultragenyx reported a net loss of $56.9 million, or $1.46 per share, basic and diluted, compared with a net loss for the second quarter of 2015 of $29.8 million, or $0.83 per share, basic and diluted. For the six months ended June 30, 2016, net loss was $109.7 million, or $2.81 per share, basic and diluted, compared with a net loss for the same period in 2015 of $51.2 million, or $1.46 per share, basic and diluted. This reflected cash used in operations of $84.6 million for the six months ended June 30, 2016 compared to $34.9 million for the same period in 2015.

Total operating expenses for the second quarter of 2016 were $58.1 million compared with $30.1 million for the same period in 2015, including non-cash stock-based compensation of $10.9 million and $5.1 million in the second quarter of 2016 and 2015, respectively.

Cash, cash equivalents, and investments were $441.8 million as of June 30, 2016.

Recent Highlights

KRN23 anti-FGF23 Monoclonal Antibody in X-Linked Hypophosphatemia (XLH) and Tumor-Induced Osteomalacia (TIO)

• Breakthrough Therapy Designation for pediatric patients with XLH. In June, the U.S. Food and Drug Administration (FDA) granted breakthrough therapy designation to KRN23 for the treatment of X-linked hypophosphatemia (XLH) in pediatric patients one year of age and older.  
• Enrollment complete in Phase 3 study in adult XLH patients; data expected in the first half of 2017. The Phase 3 study will evaluate change in serum phosphorus levels, pain, stiffness, physical function, and safety of monthly KRN23 compared with placebo over 24 weeks in 134 adult XLH patients.

rhGUS in Mucopolysaccharidosis 7 (MPS 7)

• Positive Topline Data from Phase 3 pivotal study. The study met its primary endpoint of reducing urinary GAG excretion after 24 weeks of treatment, demonstrating a reduction from baseline of 64.8 percent (p<0.0001). The Multi-domain Responder Index (MDRI) provided evidence of clinical improvement with rhGUS treatment. The MDRI score at 24 weeks of treatment, a secondary endpoint, demonstrated an overall mean improvement (±SD) of +0.5 domains (±0.80) (p=0.0527). Treatment-emergent adverse events were generally mild to moderate in severity. There were two serious adverse events including a Grade 3 treatment related anaphylactoid event and a Grade 2 unrelated event from an accidental injury.

Ace-ER in GNE Myopathy

• Enrollment complete in pivotal Phase 3 study in GNE myopathy; data expected in 2017. The randomized, double-blind, placebo-controlled international study in 89 patients is evaluating the efficacy and safety of Ace-ER compared with placebo over 48 weeks.

Corporate Updates

• Strategic collaboration established with Takeda Pharmaceutical Company Limited to develop and commercialize therapies to treat rare genetic diseases. Ultragenyx entered into a collaboration with Takeda and will receive an exclusive license to one preclinical Takeda product candidate in a pre-determined field of use, an exclusive option to co-develop and co-commercialize the product candidate in additional therapeutic areas, and an option to license up to five additional Takeda product candidates for rare diseases through a five-year research collaboration. In July, the deal closed and Takeda purchased 374,590 shares for $40 million, or an effective price of $106.78 per share.
• General Counsel appointed. In June 2016, Ultragenyx appointed Karah Parschauer as Executive Vice President, General Counsel.

Upcoming Milestones

KRN23 in XLH and TIO

• Phase 3 study in pediatric XLH patients expected to initiate in mid-2016. The study will utilize the RGI-C rickets score as the primary endpoint and will include a reference arm of oral phosphate and Vitamin D.
• 40-week data in 52 patients and 64-week data in 36 patients in the Phase 2 pediatric XLH study expected in the second half of 2016. Safety and efficacy data, including rickets scores (RSS and RGI-C) from 52 patients at 40 weeks, and height growth velocity from 36 patients at 64 weeks, will be available. 
• Ultragenyx and Kyowa Hakko Kirin plan to file for conditional marketing authorization in the European Union for the treatment of XLH around the end of 2016.
• Interim bone data from Phase 2 study in TIO expected second half 2016. The open-label, dose-finding Phase 2 study is evaluating the safety and efficacy of KRN23 in approximately fifteen adult patients. Full 24-week bone data on the first eight patients will be available in the second half of 2016.

rhGUS in MPS 7

• Ultragenyx plans to meet with FDA and EMA in the second half of 2016 to discuss plans to submit regulatory filings in the first half of 2017, based on Phase 3 study results . In Europe, the primary endpoint is the percent reduction in urinary glycosaminoglycans (GAG) excretion after 24 weeks of treatment. The EMA has indicated that some evidence or trend in improvement in clinical endpoints would also be necessary for approval. In the US, there is no primary endpoint declared; the FDA will consider the totality of data on a per-patient basis.

UX007 in Long-Chain Fatty Acid Oxidation Disorders (LC-FAOD) and Glut1 Deficiency Syndrome (Glut1 DS)

• Data at 78 weeks from the Phase 2 study in LC-FAOD expected in the second half of 2016. Data will include a comparison of major medical event rates approximately 18 months before and after UX007 treatment. Long-term safety and exercise tolerance data will also be provided.  
• Phase 2 seizure study data in Glut1 DS patients expected in the second half of 2016. The ongoing placebo-controlled study is evaluating frequency of generalized and partial tonic-clonic seizures by patient diary, absence seizures by EEG, and cognitive function.
• Phase 3 movement disorder study in Glut1 DS patients expected to initiate in the second half of 2016. The study is expected to enroll approximately 40 patients and be a randomized, double-blind, placebo-controlled, double cross-over study. The study is designed to assess the impact of UX007 on movement disorder events as recorded by a patient diary. The company is working on further substantiating the clinical meaningfulness of Glut1 DS movement disorder events prior to finalizing the study design.

Aceneuramic Acid Extended Release (Ace-ER) in GNE Myopathy

• CHMP opinion on conditional marketing authorization application in Europe expected in the second half of 2016, and a decision is expected in the first half of 2017. The company is seeking conditional marketing authorization from the European Medicines Agency (EMA) for Ace-ER in the treatment of adults with GNE myopathy based on positive data from the Phase 2 randomized, double-blind, placebo-controlled study.

About Ultragenyx

Ultragenyx is a clinical-stage biopharmaceutical company committed to bringing to market novel products for the treatment of rare and ultra-rare diseases, with a focus on serious, debilitating genetic diseases. Founded in 2010, the company has rapidly built a diverse portfolio of product candidates with the potential to address diseases for which the unmet medical need is high, the biology for treatment is clear, and for which there are no approved therapies.

Ultragenyx has completed a Phase 3 study of recombinant human beta-glucuronidase (rhGUS) in patients with mucopolysaccharidosis 7 (MPS 7), a rare lysosomal storage disease, and is currently conducting a Phase 3 study of aceneuramic acid extended-release (Ace-ER) in patients with GNE myopathy, a progressive muscle-wasting disorder; a Phase 2 clinical study for UX007 in patients with glucose transporter type-1 deficiency syndrome (Glut1 DS), a brain energy deficiency; a Phase 2 clinical study of UX007 in patients severely affected by long-chain fatty acid oxidation disorders (LC-FAOD), a genetic disorder in which the body is unable to convert long chain fatty acids into energy; and Phase 2 and Phase 3 studies of KRN23, an antibody targeting fibroblast growth factor 23 (FGF23), in patients with X-linked hypophosphatemia (XLH) and tumor induced osteomalacia (TIO), both rare diseases that impair bone mineralization.

The company is led by a management team experienced in the development and commercialization of rare disease therapeutics. Ultragenyx’s strategy is predicated upon time and cost-efficient drug development, with the goal of delivering safe and effective therapies to patients with the utmost urgency.
