AcelRx Pharmaceuticals Submits New Drug Application for ARX-04 for the Treatment of Moderate-To-Severe Acute Pain

REDWOOD CITY, Calif., Dec. 13, 2016 /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 that it has submitted a New Drug Application (NDA) under section 505(b)(2) with the U.S. Food and Drug Administration (FDA) for ARX-04 (sufentanil sublingual tablet, 30 mcg) for the treatment of patients experiencing moderate-to-severe acute pain in a medically supervised setting.

The NDA contains results of the entire ARX-04 clinical program, including data from four clinical trials in which ARX-04 was assessed as a treatment for moderate-to-severe acute pain in postoperative and emergency department patients. In each of these clinical studies, patients treated with ARX-04 demonstrated improvements in pain intensity as early as 15-to-30 minutes after the start of dosing. Adverse events reported in the studies were typical of opioid therapy, with the most common being nausea, headache, vomiting and dizziness. For more details on these trials, please visit the ARX-04 webpage on the AcelRx website.

"During my career before AcelRx, I saw first-hand the challenges of treating pain with IV opioids; and through our market research, it's clear that my experiences were not isolated," explained Dr. Pamela Palmer, co-founder and chief medical officer at AcelRx. "Even today, needs exist for non-invasive, cost-effective pain management in the emergency room, ambulatory surgical center, pre-hospital care, battlefield, and other diverse medical settings. We believe that ARX-04, with its sublingual delivery, could offer physicians and nurses a valuable treatment option in the treatment of moderate-to-severe acute pain."

Howie Rosen, AcelRx's chief executive officer, added, "The submission of the ARX-04 NDA is a significant corporate milestone for AcelRx. We are in the process of completing our commercialization plans so that we will be ready for an initial pilot launch in 2017, should ARX-04 be approved by the FDA. We also are using the NDA to prepare a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) with a target submission date in the first half of 2017 and are continuing to talk with potential European partners for ARX-04."

Clinical and Rehabilitative Medicine Research Program (CRMRP)

ARX-04 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. The CRMRP was established in 2008 to foster research and technology advances for regeneration, restoration, and rehabilitation of traumatic injuries.

In accordance with USAMRMC guidelines, in the conduct of clinical research, AcelRx has adhered to the policies regarding the protection of human subjects as prescribed by Code of Federal Regulations (CFR) Title 45, Volume 1, Part 46; Title 32, Chapter 1, Part 219; and Title 21, Chapter 1, Part 50 (Protection of Human Subjects).

About 505(b)(2) Designation

Under the FDA's 505(b)(2) regulatory pathway, FDA may consider data not developed by the applicant when reviewing an NDA. It also allows the potential for fewer pivotal Phase 3 studies and/or the enrollment of a smaller number of patients than is typical. These allowances may reduce the length and cost of a drug's regulatory path. In addition, the drug, once approved by the FDA, is eligible for three years of market exclusivity.
