MENLO PARK, CA, USA I July 6, 2015 I Versartis, Inc. (VSAR), an endocrine-focused biopharmaceutical company that is developing VRS-317, a novel, long-acting form of recombinant human growth hormone (rhGH) for growth hormone deficiency (GHD), today announced that the US Food and Drug Administration (FDA) has removed the partial clinical hold on the Company’s Investigational New Drug Application for VRS-317. With this action, the Company will proceed with the Phase 3 registration trial, VELOCITY, of VRS-317 in children with GHD.

Jay Shepard, Chief Executive Officer, said, “Our team has continued to work diligently with the FDA and we are excited to be moving forward with the Phase 3 clinical trial of VRS-317 in pediatric GHD patients. There is a significant need for these patients to have treatment options that are less burdensome than the daily injections that are the current standard of care. We continue to expect VRS-317 to be the first and longest-acting rhGH product candidate in development to reach the market and, with the removal of the partial clinical hold, we remain on track to achieve this goal.”

The Company reaffirmed its previously stated anticipated milestones for the VELOCITY Phase 3 clinical trial, including interim 6-month mean height velocity data by the end of 2016 and top line data on the 12-month mean height velocity primary endpoint by mid-2017, enabling a potential Biologics License Application submission, followed by a potential FDA approval by late-2018.

About the VELOCITY Trial

The Versartis Long-Acting Growth Hormone in Children compared To Daily rhGH (VELOCITY) Trial is a randomized, open-label, Phase 3 registration trial being conducted in the United States, Western Europe and Canada. This study is expected to enroll up to 136 naive to treatment, pre-pubertal children with GHD and will include a 3:1 randomization of 3.5 mg/kg VRS-317 twice-monthly to daily rhGH at the highest approved dose on the labels of Genotropin(R) and Norditropin(R) 34 ug/kg/day. The primary endpoint is non-inferiority between the two treatment groups for 12-month mean height velocity. After completing the Phase 3 trial, all patients will be offered the opportunity to continue treatment with VRS-317 in the ongoing pediatric Extension Study.

About Versartis, Inc.

Versartis, Inc. is an endocrine-focused biopharmaceutical company initially developing VRS-317, a novel, long-acting form of recombinant human growth hormone for the treatment of growth hormone deficiency (GHD). VRS-317 is intended to reduce the burden of daily injection therapy by requiring significantly fewer injections, potentially improving compliance and, therefore, treatment outcomes. The Company completed the Phase 2a stage of a Phase 1b/2a trial evaluating weekly, twice-monthly and monthly dosing regimens of VRS-317 in children with GHD in June 2014 and initiated a global Phase 3 registration trial, VELOCITY, in GHD children in January 2015. In addition, the Company initiated a Phase 2/3 trial in Japan for children with GHD in April 2015. Additional information on the VELOCITY trial can be found at www.velocitytrial.com.
