AcelRx Pharmaceuticals Presents Results from Phase 3 Study of ARX‑04 following Ambulatory Abdominal Surgeries at Euroanaesthesia

REDWOOD CITY, Calif., May 26, 2016 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (NASDAQ: ACRX) today announced that the Company and its investigators will be presenting Phase 3 SAP301 study results at Euroanaesthesia 2016, which is taking place in London, UK on May 28-30, 2016. In the SAP301 study, patients with moderate-to-severe acute pain following abdominoplasty, hernioplasty or laparoscopic abdominal surgeries were randomized to receive either ARX-04 (sufentanil sublingual 30 mcg tablet) or a placebo sublingual tablet. The study met its primary endpoint with statistically significant pain intensity differences to baseline over the 12-hour study period (SPID12) in favor of ARX-04 (p<0.001). When analyzed by type of surgery, treatment with ARX-04 resulted in a statistically significant benefit over placebo in each surgery type. ARX-04 was well tolerated in the trial, with nausea, headache and vomiting being the most common treatment-emergent adverse events reported.

Details on the presentation time are as follows:

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 acute pain. The Company's late-stage pipeline includes ARX-04 (sufentanil sublingual tablet, 30 mcg) designed for the treatment of moderate-to-severe acute pain in a medically supervised setting; and Zalviso™ (sufentanil sublingual tablet system) designed for the management of moderate-to-severe acute pain in adult patients in the hospital setting.

ARX-04 delivers 30 mcg sufentanil, a high therapeutic index opioid, sublingually through a disposable, pre-filled, single-dose applicator. AcelRx has reported positive results from the pivotal Phase 3 SAP301 ambulatory surgery study, and has advanced ARX-04 into studies in emergency room patients (SAP302) and post-operative patients 40 years and older (SAP303). Zalviso delivers 15 mcg sufentanil sublingually through a non-invasive delivery route via a pre-programmed, patient-controlled analgesia device. In response to the New Drug Application (NDA) AcelRx submitted to the U.S. Food and Drug Administration (FDA) seeking approval for Zalviso, AcelRx received a Complete Response Letter (CRL) on July 25, 2014. The FDA has requested an additional clinical study (IAP312), which AcelRx is planning to initiate once supplies are available, have been tested with acceptable results, and clinical sites are ready, in order to support its NDA resubmission.
