Versartis Announces Two Abstracts from Ongoing Pediatric Extension Study of Somavaratan Selected for Late-Breaker Presentations at the Endocrine Society’s 98th Annual Meeting

MENLO PARK, Calif., March 14, 2016 -- Versartis, Inc. (NASDAQ:VSAR), an endocrine-focused biopharmaceutical company that is developing somavaratan (VRS-317), a novel, long-acting form of recombinant human growth hormone (rhGH) for growth hormone deficiency (GHD), today announced that detailed two-year, safety, efficacy and adherence data from its ongoing Extension Study of somavaratan in children with GHD will be featured in two late-breaker presentations at the Endocrine Society's 98th Annual Meeting & Expo (ENDO 2016), to be held April 1-4, 2016, in Boston, MA. The Extension Study is a long-term safety study that was initiated in March 2014 as patients completed the Phase 1b/2a clinical trial evaluating somavaratan therapy in treatment-naive, pre-pubertal GHD children.

Bert Bakker, MD, PhD, Senior Vice President, Medical Affairs, commented, "We are very pleased to have in-depth confirmatory data from our ongoing pediatric Extension Study selected for two late-breaker presentations at this year’s Endocrine Society Annual Meeting. We appreciate that the Endocrine Society recognizes that the important results coming from Versartis’ ongoing clinical trial program in Pediatric GHD patients would be of interest to meeting attendees. We look forward to sharing details on the safety, efficacy and patient adherence of somavaratan at this important event for the global endocrinology community.”

The abstracts are now available on the ENDO website and can be accessed using the links below.
