Company Update (NASDAQ:ACRX): AcelRx Pharmaceuticals Inc Completes Patient Enrollment in Remaining Phase 3 Studies of ARX-04 as a Potential Treatment of Moderate-to-Severe Acute Pain

AcelRx Pharmaceuticals Inc (NASDAQ:ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of moderate-to-severe acute pain, announced that it has completed patient enrollment in the two remaining Phase 3 studies of ARX-04 (sufentanil sublingual tablet, 30 mcg):

  • SAP302 is a single-arm, open-label study that enrolled 76 adult patients who presented in the emergency room with moderate-to-severe acute pain associated with trauma or injury. The primary endpoint is the time-weighted summed pain intensity difference (SPID) to baseline over the first hour, or SPID1.
  • SAP303 is a multicenter, open-label study that enrolled 139 patients 40 years and older who had moderate-to-severe acute pain following a surgical procedure with general anesthesia or spinal anesthesia (except those who received intrathecal opioids). The primary efficacy endpoint of this study is SPID over the 12-hour study period, or SPID12.

Data from both studies are currently being analyzed, and top-line results are expected to be available in the third quarter of 2016.

Dr. Pamela Palmer, AcelRx’s chief medical officer and co-founder, stated, “Pending positive results for SAP302 and SAP303, we believe we are on track to file a New Drug Application for ARX-04 with the U.S. Food and Drug Administration (FDA) by the end of this year.”

Howie Rosen, AcelRx’s chief executive officer, added, “The completion of enrollment in these ARX-04 clinical studies represents a tremendous accomplishment for AcelRx. With $106 million in cash on hand (as of the end of 1Q), I believe we are in a good financial position to drive ARX-04 through the regulatory process.”
