NOVATO, Calif., Nov. 02, 2017 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ:RARE), a biopharmaceutical company focused on the development of novel products for rare and ultra-rare diseases, today reported its financial results and corporate update for the quarter ended September 30, 2017.

"Burosumab and vestronidase alfa regulatory submissions have been accepted and regulatory review is progressing well in both the US and European Union. We are preparing for a near-term potential launch of vestronidase alfa with a PDUFA date of November 16," said Emil D. Kakkis, M.D., Ph.D., Chief Executive Officer and President of Ultragenyx.

Third Quarter 2017 Financial Results

For the third quarter of 2017, Ultragenyx reported a net loss of $79.2 million, or $1.87 per share, basic and diluted, compared with a net loss of $64.9 million, or $1.64 per share, basic and diluted in the third quarter of 2016. For the nine months ended September 30, 2017, net loss was $220.4 million, or $5.22 per share, basic and diluted, compared with a net loss for the same period in 2016 of $174.6 million, or $4.46 per share, basic and diluted. This reflected cash used in operations of $172.0 million for the nine months ended September 30, 2017 compared to $113.3 million for the same period in 2016.

Total operating expenses for the third quarter of 2017 were $83.9 million compared with $65.9 million for the same period in 2016, including non-cash stock-based compensation of $17.2 million and $13.7 million for the third quarter of 2017 and 2016, respectively. Total operating expenses for the nine months ended September 30, 2017 were $232.3 million compared with $177.6 million for the same period in 2016, including non-cash stock-based compensation of $48.5 million and $34.8 million in the first nine months of 2017 and 2016, respectively. The increase in total operating expenses is due to the increase in development, commercial, and general and administrative costs as the company grows and advances its pipeline.

Cash, cash equivalents, and investments were $396.0 million as of September 30, 2017.

Recent Highlights

Burosumab (KRN23) anti-FGF23 Monoclonal Antibody in X-Linked Hypophosphatemia (XLH)

  • US BLA for burosumab accepted and PDUFA action date set for April 17, 2018. The U.S. Food and Drug Administration (FDA) has accepted the Biologics License Application (BLA) for burosumab to treat pediatric and adult patients with X-Linked Hypophosphatemia (XLH) and has granted Priority Review status. The Agency has indicated that it is not currently planning to hold an advisory committee meeting to discuss the BLA. The FDA has designated burosumab as a drug for a "rare pediatric disease", enabling issuance of a priority review voucher if burosumab is approved.
  • Bone biopsy data from the first six adult patients demonstrate substantial improvement in severe osteomalacia and are included in FDA review. We now have six total available paired bone biopsies from the 48-week open label bone quality study, and they will be included in the BLA review. The bone biopsy data demonstrated substantial improvement in osteomalacia from severe to mild disease. The six patients had mean osteoid volume/bone volume decreases from 24.3 percent to 7.0 percent, representing a 71 percent improvement. In our past discussions with FDA, they emphasized that improvement in osteomalacia could also be considered an important outcome for adults with XLH.
  • Significant improvement in rickets and bowing observed in early 40-week data from pediatric XLH patients under 5 years old. At ASBMR in September, data from the Phase 2 under 5 study demonstrated that treatment with burosumab significantly improved serum phosphorus levels, bowing, and rickets scores. Burosumab increased mean serum phosphorus levels into the low normal range after one week of treatment, and these levels were maintained through week 40. The patients had more severe rickets at baseline than the older children that we have previously studied, and every patients showed substantial healing of rickets at week 40. These younger patients also showed a significant improvement in bowing, which was readily visible on X-rays of some patients in only 40 weeks. The safety profile observed in this study was consistent with other burosumab studies. The data support the concept that early treatment could have a more profound impact on the bone deformities that would typically affect XLH patients throughout their lives.

Burosumab (KRN23) anti-FGF23 Monoclonal Antibody in tumor-induced osteomalacia (TIO)

  • Treatment of TIO patients shows improved serum phosphorus levels and effect on bone disease and physical function. Data from the open-label Phase 2 study presented at ASBMR showed increases in mean serum phosphorus levels, significant increases in bone turnover markers, improvements in histomorphometric indices of osteomalacia in 3 of the 4 patients who completed 48 weeks of treatment with bone biopsy, and statistically significant improvements in patient-reported outcomes. The safety profile was consistent with other burosumab studies.


  • Definitive merger agreement signed for the acquisition of Dimension Therapeutics. We have entered into a definitive merger agreement with Dimension under which Ultragenyx will acquire all of the outstanding shares of common stock of Dimension for $6.00 per share, or approximately $151 million in cash, based on shares outstanding as of the date of the merger agreement. The transaction is structured as a tender offer and will be funded through our existing cash resources. The transaction could close as early as November 7, 2017, depending on the satisfaction of the conditions for the merger.

Upcoming Key Milestones

Burosumab in XLH

  • PDUFA action date of April 17, 2018. The BLA was accepted for priority review in October 2016.
  • Opinion from CHMP on the burosumab Conditional MAA for pediatric XLH expected around the end of 2017. The MAA was submitted and accepted for review by the European Medicines Agency (EMA) in December 2016.
  • 48-week data from the Phase 3 study in adult XLH patients expected by the end of 2017. Data will include change in serum phosphorus levels as well as pain, stiffness and physical function.
  • Bone biopsy results from all 11 patients in bone quality study expected in early 2018.

Vestronidase alfa or rhGUS in Mucopolysaccharidosis 7 (MPS 7)

  • PDUFA goal date of November 16, 2017 and CHMP opinion in first half of 2018. The FDA has granted vestronidase alfa Priority Review Status, and the BLA has a PDUFA action date for a decision of November 16, 2017. The Committee for Medicinal Products for Human Use (CHMP) opinion is expected in the first half of 2018.

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

  • Phase 3 study in FAOD patients. We continue to plan for discussions with regulators regarding the Phase 3 study in FAOD patients by the end of 2017.
  • Phase 3 movement disorder study in Glut1 DS patients ongoing. The randomized, double-blind, placebo-controlled, cross-over study is enrolling approximately 40 patients. The primary endpoint compares the frequency of disabling paroxysmal movement disorder events with UX007 to placebo, as recorded by a daily electronic diary.


  • Analyst Day to be held at 8:00 am ET on December 4, 2017 in New York. The company will review development progress and commercial readiness, and outside experts will share their perspectives during the Analyst Day.
