Inc. (the &#8220;Company&#8221;) announced modifications to the plan for its ongoing open label pediatric GHD Phase 3 registration trial for somavaratan (formerly &#8220;VRS-317&#8221;), known as the VELOCITY trial.&nbsp;&nbsp;In particular, based on dialog with the U.S. Food and Drug Administration (FDA) and our expert statistical consultants regarding the statistical aspects of the study design, the company has eliminated the planned company review of interim efficacy analysis that was to be conducted after all patients had reached 6 months on study.&nbsp;&nbsp;Removal of the company review of unblinded interim efficacy analysis preserves the statistical power of the trial, greatly reduces the potential for study bias and provides greater assurance of data integrity.&nbsp;&nbsp;As previously disclosed, specific study data will be monitored through periodic reviews by an independent Data and Safety Monitoring Board (DSMB) but any height velocity data reviewed by the DSMB will remain blinded to the Company as well as investigators and patients.&nbsp;&nbsp;</p>

Item 8.01
Other Events.
On Sept. 15, Versartis. Inc. (the "Company") announced modifications to the plan for its ongoing open label pediatric GHD Phase 3 registration trial for somavaratan (formerly "VRS-317"), known as the VELOCITY trial.  In particular, based on dialog with the U.S. Food and Drug Administration (FDA) and our expert statistical consultants regarding the statistical aspects of the study design, the company has eliminated the planned company review of interim efficacy analysis that was to be conducted after all patients had reached 6 months on study.  Removal of the company review of unblinded interim efficacy analysis preserves the statistical power of the trial, greatly reduces the potential for study bias and provides greater assurance of data integrity.  As previously disclosed, specific study data will be monitored through periodic reviews by an independent Data and Safety Monitoring Board (DSMB) but any height velocity data reviewed by the DSMB will remain blinded to the Company as well as investigators and patients.
The Company reiterated its expectation that it will have top line data on the 12-month mean height velocity primary endpoint VELOCITY trial by mid-2017, enabling a potential Biologics License Application submission, followed by a potential FDA approval by late-2018.
