Here’s Why Versartis Inc (VSAR) Shares Crashed Today

Friday turned out to be a nightmare for Versartis Inc (NASDAQ:VSAR) investors, after the drug maker reported negative Phase 3 VELOCITY data in pediatric GHD patients. In the pivotal study, treatment with twice-monthly somavaratan did not demonstrate non-inferiority as measured by the difference of mean annualized height velocities between the drug and active comparator Genotropin (intent-to-treat (ITT) population).

Versartis shares reacted to the news, crashing over 80% to $3.45 in pre-market trading.

Versartis CEO Jay Shepard commented, “We are very surprised and disappointed to learn the outcome of the VELOCITY trial. Somavaratan showed height velocity in the range we had hoped, but it was not sufficient to demonstrate non-inferiority in this trial […] We have done an initial analysis of the top-line data and are continuing to thoroughly review the results to gain greater insight into the trial outcome. We plan to provide a corporate update later this year. I would like to thank the investigators, pediatric GHD patients and families that participated in the VELOCITY trial.”
