NOVATO, Calif, May 04, 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 March 31, 2017.

"We have started the year with positive data from our pediatric and adult studies of burosumab and look forward to moving this key program through the regulatory process in both the US and Europe this year," said Emil D. Kakkis, M.D., Ph.D., Chief Executive Officer and President of Ultragenyx.

First Quarter 2017 Financial Results

For the first quarter of 2017, Ultragenyx reported a net loss of $68.3 million, or $1.63 per share, basic and diluted, compared with a net loss of $52.8 million, or $1.35 per share, basic and diluted in the first quarter of 2016. This reflected cash used in operations of $61.2 million for the quarter ended March 31, 2017 compared to $44.9 million for the same period in 2016.

Total operating expenses for the first quarter of 2017 were $70.0 million compared with $53.6 million for the same period in 2016, including non-cash stock-based compensation of $14.5 million and $10.2 million for the first three 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.
