REDWOOD CITY, Calif., Oct. 8, 2015 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain, today provided a regulatory update on Zalviso™ (sufentanil sublingual tablet system) intended for the management of moderate-to-severe acute pain in adult patients in the hospital setting. The company has received formal minutes of the telephonic meeting held in early September 2015, with the Division of Anesthesia, Analgesia, and Addiction Products of the Food and Drug Administration (FDA). As reflected in the minutes, the Division restated at the meeting a request for clinical data to complement other data AcelRx has developed to assess the overall performance of the Zalviso device.
The company is planning to submit a protocol to the Division for a clinical study in post-operative patients designed to evaluate the effectiveness of changes made to enhance product performance. AcelRx expects to be ready to initiate the study in the first quarter of 2016, and likely will await comments on the protocol from the Division. The company will be prepared to work with the FDA to facilitate the timely study initiation.
"We have been preparing a clinical study to investigate the use of Zalviso in a more diverse post-surgical population than in our original Phase 3 studies," stated Pamela P. Palmer, MD, PhD, chief medical officer of AcelRx, "so we are modifying the design of this study to include endpoints that we believe will address the Division's concerns."
"The teleconference and meeting minutes were constructive, because they further clarified the Division's position," stated Howie Rosen, interim chief executive officer of AcelRx. "Even as ARX-04 advances through clinical development, Zalviso remains an important product for AcelRx, especially given its recent approval in Europe. We look forward to moving Zalviso toward resubmission, review and ultimate approval."
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) for the treatment of moderate-to-severe acute pain in a medically supervised setting; and Zalviso™ (sufentanil sublingual tablet system) 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 a study (SAP302) in emergency room patients. Zalviso delivers 15 mcg sufentanil sublingually through a non-invasive delivery route via a pre-programmed, patient-controlled analgesia device. AcelRx submitted a New Drug Application (NDA) for Zalviso and received a Complete Response Letter (CRL) from the FDA on July 25, 2014. The FDA subsequently requested an additional clinical study to evaluate the effectiveness of product changes made in response to the CRL, and the Company is working with the FDA regarding the resubmission of the Zalviso NDA.
