REDWOOD CITY, Calif., Dec. 23, 2015 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the intended treatment of acute pain, reported that the Committee for Medicinal Products for Human Use (CHMP) at the European Medicines Agency (EMA) has confirmed that a Marketing Authorization Application (MAA) for ARX-04 may be submitted in the European Union (EU) under the Agency's centralized procedure. ARX-04 (sufentanil sublingual tablet, 30 mcg) is being developed for the treatment of moderate-to-severe acute pain in adult patients administered by a healthcare professional in a medically supervised setting.
"We appreciate the CHMP's consideration of ARX-04 for regulatory review under the centralized process, which we expect will make our planned MAA filing with the EMA much more efficient," commented Dr. Pamela Palmer, co-founder and chief medical officer of AcelRx. "The EMA's centralized procedure is typically limited to products the EMA believes constitute significant therapeutic, scientific or technical innovations, characteristics we believe ARX-04 possesses."
For eligible drugs, the centralized procedure permits the submission of a single marketing application to the EMA that, if approved, allows the drug to be marketed in all 27 EU member states, as well as in the three European Economic Area (EEA) countries: Iceland, Liechtenstein and Norway.
ARX-04 is currently being studied in an open-label Phase 3 study (SAP302) in adult patients who present in the emergency room with acute moderate-to-severe pain associated with trauma or injury, and an additional Phase 3 study (SAP303) is planned in postoperative patients with acute moderate-to-severe pain. An earlier Phase 3 trial (SAP301) in patients with acute moderate-to-severe pain following ambulatory abdominal surgery demonstrated that patients administered ARX-04 experienced significantly greater pain relief compared to those receiving placebo, as measured by the time-weighted summed pain intensity difference over the first 12 hours of treatment (SPID12) (p<0.001). AcelRx expects to file marketing applications to both the EMA and the U.S. Food and Drug Administration (FDA) for ARX-04.
About AcelRx Pharmaceuticals, Inc.
AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative sublingual therapies intended 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, a study in post-operative patients 40 years of age or older, 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.
