"Our pre-NDA meeting with the FDA was productive and provided specific guidance for meeting the FDA's requirements for submitting a New Drug Application for ARX-04," stated Dr. Pamela Palmer, co-founder and chief medical officer of AcelRx. "Enrollment in the postoperative study (SAP303) is estimated to take three months, and is expected to yield results to help support the NDA submission and review. In addition, we are encouraged that the FDA has agreed to consider a portion of the Zalviso safety database when reviewing the ARX-04 NDA."
ARX-04 is a non-invasive investigational product candidate consisting of 30 mcg sufentanil tablets delivered as often as once an hour 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 pain in the hospital, and post-operative patients following short-stay surgery, who do not require more long-term patient-controlled analgesia (PCA). ARX-04 is funded in part by the U.S. Army Medical Research and Materiel Command (USAMRMC).
Based on its market research, the Company estimates there are more than 51 million injury-related emergency department visits annually that on average receive two doses of opioids for moderate-to-severe pain in the United States.
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™ 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 a study (SAP302) in emergency room patients. In addition, AcelRx intends to initiate SAP303, with a focus on enrolling patients greater than 40 years of age, allowing for administration of ARX-04 for up to 12 hours, in the first quarter of 2016. 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 and the Company is working with the FDA regarding the resubmission of the Zalviso NDA and initiation of a clinical study to support resubmission.
