REDWOOD CITY, Calif.--(BUSINESS WIRE)--

Heron Therapeutics, Inc. (HRTX), previously announced that the U.S. Food and Drug Administration (FDA) would not take action on the New Drug Application (NDA) for SUSTOL^® (granisetron) Injection, extended release by the original Prescription Drug User Fee Act (PDUFA) goal date of January 17, 2016 and would delay taking action until late February 2016. The FDA has informed the Company that it has not concluded its review of the NDA and could not yet provide the Company with an anticipated action date, but indicated that they will communicate the new action date to the Company later this week.
