AcelRx Pharmaceuticals Presents Results from Phase 3 Study of ARX‑04 in the Emergency Department at the International Society for Burn Injuries

REDWOOD CITY, CA, USA I August 29, 2016 I AcelRx Pharmaceuticals, Inc. (NASDAQ: ACRX) today announced that the Company and its investigators will be presenting results from the Phase 3 SAP302 study of ARX-04 (sufentanil sublingual tablet, 30 mcg) in 76 patients who were treated for moderate-to-severe acute pain in the emergency department. An oral presentation reviewing these results, including the types of injuries that were sustained by patients in the study, will be made at the International Society for Burn Injuries (ISBI), which is taking place August 29 – September 1 in Miami, Florida.

As previously reported, adult patients treated with ARX-04 in this study experienced a mean pain intensity difference of 2.9 from a baseline of 8.1 on a validated 0 – 10 numeric rating scale at 60 minutes, meeting the study’s primary objective. Injuries sustained by patients in SAP302 included fractures, sprains/strains, lacerations and burns, among others. Study participants tolerated ARX-04 well, with nausea (9%), somnolence (5%) and vomiting (4%) comprising the most commonly reported adverse events.

The study additionally concluded that ARX-04 had no overall impact on cognitive function.

About ARX-04

ARX-04 is a non-invasive investigational product candidate consisting of a 30 mcg sufentanil tablet delivered sublingually via a disposable, pre-filled, single-dose applicator (SDA). AcelRx is developing ARX- 04 for the management of moderate-to-severe acute pain in a variety of medically supervised settings, including the emergency room, outpatient or ambulatory surgery, non-surgical patients experiencing moderate-to-severe acute pain in the hospital, and post-operative patients following short-stay surgery, who do not require more long-term patient-controlled analgesia (PCA).

The ARX-04 Phase 3 clinical program is comprised of three studies in patients with moderate-to-severe acute pain: SAP301, a double-blind, placebo-controlled trial in ambulatory abdominal surgery patients; SAP302, an open-label trial in adult emergency room patients; and SAP303, an open-label trial in postoperative patients. Results of SAP301, which were presented in 2015 at the American Society of Anesthesiologists annual meeting, may be viewed on the AcelRx website.

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.
