AcelRx Hears from FDA on Zalviso Protocol
AcelRx Pharmaceuticals, Inc. says it has received comments from FDA’s Division of Anesthesia, Analgesia and Addiction Products on its proposed protocol for a Phase 3 clinical study (IAP312) to assess the overall performance of Zalviso (sufentanil sublingual tablet system) for managing moderate-to-severe acute pain in adult patients in the hospital setting. According to the company, FDA requested the IAP312 study in a 7/25/14 Complete Response Letter to the company’s NDA. It plans to begin the study this quarter in about 310 post-operative patients who will self-administer 15 mcg Zalviso for 24-to-72 hours. It says it will also collect information that was requested by FDA from three already completed Phase 3 trials.
