About DSUVIA™ (sufentanil sublingual tablet), 30 mcg
DSUVIA^™ (sufentanil sublingual tablet, SST, 30 microgram), known as ARX-04 outside the United States, is designed to treat moderate-to-severe acute pain and dosing errors associated with IV administration via its non-invasive single-dose applicator (SDA) in medically supervised settings. Sufentanil is an opioid analgesic currently marketed for intravenous (IV) and epidural anesthesia and analgesia. The sufentanil pharmacokinetic profile when delivered sublingually potentially avoids the high peak plasma levels and short duration of action observed with IV administration. In the EU, the European Medicines Agency (EMA) has notified the company that the ARX-04 Marketing Authorization Application (MAA) is under scientific review.

Clinical and Rehabilitative Medicine Research Program (CRMRP)
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. 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 AcelRx Pharmaceuticals, Inc.
AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of moderate-to-severe acute pain. AcelRx's proprietary, non-invasive sublingual formulation technology delivers sufentanil with a consistent pharmacokinetic profile. The company is simultaneously developing ZALVISO^® (sufentanil sublingual tablet system, SST system, 15 microgram) as an innovatively designed patient-controlled analgesia (PCA) system for treatment of moderate-to-severe pain in medically supervised settings. The company recently completed a Phase 3 clinical trial, IAP312, which included input from the FDA on the study protocol. This study was designed to evaluate the effectiveness of changes made to the functionality and usability of the ZALVISO device, to evaluate the incidence of inadvertent dosing, and to take into account comments from the FDA on the study protocol. AcelRx intends to resubmit the NDA for ZALVISO to the FDA by the end of the year. AcelRx has successfully received EU Marketing Approval for ZALVISO^® in the EU. Grunenthal Group holds the rights for ZALVISO® in Europe, where a commercialization across multiple countries is underway. In June 2017, ZALVISO®   was selected for a Red Dot Award in the category of Product Design – Life Sciences and Medicine.
