REDWOOD CITY, Calif., Feb. 27, 2017 /PRNewswire/ -- 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 today the U.S. Food and Drug Administration (FDA) has accepted the company's New Drug Application (NDA) under section 505(b)(2) for DSUVIA™ (formerly ARX-04) (sufentanil sublingual tablet, 30 mcg) for the treatment of patients with moderate-to-severe acute pain in a medically supervised setting. The acceptance of the NDA indicates that the FDA has deemed the application sufficiently complete to allow a substantive review. The FDA has also set a Prescription Drug User Fee Act (PDUFA) date of October 12, 2017. The PDUFA date is the target date set by the FDA to communicate its decision on the New Drug Application.
"It is truly gratifying to see years of work developing a sublingual formulation of sufentanil and conducting multiple clinical trials finally come to this stage," stated Pamela P. Palmer, MD, PhD, AcelRx's chief medical officer and co-founder. "We believe that DSUVIA will provide physicians and their patients a non-invasive treatment alternative in emergency medicine and short-stay or ambulatory surgeries for the treatment of moderate-to-severe acute pain."
The NDA for DSUVIA includes data from four trials including SAP301 and SAP202, two randomized double-blind, placebo-controlled studies, which enrolled a total of 261 patients (198 received DSUVIA) suffering with moderate-to-severe acute pain due to soft-tissue/visceral (SAP301) or musculoskeletal procedures (SAP202). In addition, the data package includes findings from SAP302 and SAP303, two Phase 3 open-label safety and efficacy studies, which enrolled a total of 216 patients with moderate-to-severe acute pain, who had either presented at an emergency department with trauma or injury or undergone various surgical procedures, respectively. The NDA includes safety results from these studies as well as from 323 patients enrolled in the ZALVISO (sufentanil sublingual tablet system) clinical program who had dosed the first two 15 mcg doses within approximately 20 minutes, as bioequivalence was established between this regimen and a single dose of 30 mcg DSUVIA. In total, the safety data base for DSUVIA includes over 900 patients.
The FDA has also communicated to AcelRx that it plans to hold an Advisory Committee meeting to review the DSUVIA application. The date of this meeting is yet to be determined.

DSUVIA is funded in part by the Clinical and Rehabilitative Medicine Research Program (CRMRP) of the U.S. Army Medical Research and Materiel Command (USAMRMC) under contract No. W81XWH-15-C-0046.
