AcelRx Pharmaceuticals to Present ARX-04 Analysis for Treatment of Moderate-to-Severe Acute Pain in Obese Patients at The Obesity Society Annual Meeting

REDWOOD CITY, Calif., Oct. 31, 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 an upcoming poster presentation at The Obesity Society Annual Meeting, which is taking place October 31 - November 4, 2016 in New Orleans, LA.  

This poster presents data that shows that obese patients treated with ARX-04 (sufentanil sublingual tablet, 30 mcg) in the Phase 3 SAP301 study following ambulatory abdominal surgery experienced greater pain relief over the 12-hour study period (SPID-12) compared to those treated with a placebo. The experience of obese patients in the study was similar to that of patients with lower BMIs. Nausea (23%) and headache (10%) were the only adverse events reported by more than one patient in the obese cohort treated with ARX-04. Overall, while sample sizes were limited, the conclusion of this analysis was that safety and efficacy results were consistent across the entire study population, regardless of BMI.

Dr. Pamela Palmer, chief medical officer and co-founder of AcelRx added, "Obese patients require careful weight-based dosing regimens when using many opioid pain medications, such as morphine. The evidence from this study suggests that ARX-04 has the potential for fixed-dose pain management for these patients."
