REDWOOD CITY, Calif., March 6, 2012 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), ("AcelRx"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute and breakthrough pain, reported dosing of the first patient in a Phase 3 study for ARX-01, the Sufentanil NanoTab PCA System, its novel sublingual patient-controlled analgesia system. This first ARX-01 Phase 3 study is a randomized, double-blind, placebo-controlled efficacy and safety trial in adults following open abdominal surgery. Approximately 150 adults, randomized 2:1 to active or placebo groups, will be treated for post-operative pain for a minimum of 48 hours and, as needed, up to 72 hours after randomization. The study will be conducted at 12 academic and community hospitals in the United States.
The remainder of the planned Phase 3 clinical program for ARX-01 includes a second randomized, double-blind, placebo-controlled efficacy and safety study comparing Sufentanil NanoTabs to placebo for post-operative pain control following major joint replacement surgery, and an open-label active-comparator study comparing ARX-01 to the current standard of care, intravenous patient-controlled analgesia, or IV PCA, with morphine.
"We are extremely pleased to have our ARX-01 Phase 3 clinical program underway. This year is an exciting time for AcelRx, with the delivery of top-line data from all three Phase 3 clinical trials expected by late 2012 or early 2013," said Richard King, AcelRx's Chief Executive Officer. Mr. King added, "We hope to be in a position to file an NDA with the FDA in mid-2013 for ARX-01. We believe ARX-01 is highly differentiated from the current standard of care for post-operative pain management, IV PCA. We look forward to the time when ARX-01 will be available to patients and health care providers as a non-invasive, pre-programmed, high therapeutic index opioid alternative to IV PCA."
About Post-Operative Pain
Acute pain management in the hospital, in particular post-operative analgesia, remains a challenge for healthcare providers with up to 75% of patients reporting inadequate pain relief after surgery. Inadequate treatment of post-surgical pain can lead to decreased mobility, which increases the risks for the medical complications, including deep vein thrombosis and partial lung collapse, potentially resulting in extended hospital stays. Over 23 million procedures per year result in moderate to severe post-operative pain in the major pharmaceutical markets (US, 5 main EU countries and Japan), resulting in $5.1 billion of acute pain treatment product sales. Current standard of care for managing post-operative pain is IV PCA, typically utilizing morphine or hydromorphone. However, there are many deficiencies associated with the current use of IV PCA that can negatively impact patient safety, well-being and recovery. These include drug-related side effects associated with morphine or hydromorphone, complications associated with IV delivery, and medication delivery errors typically associated with misprogramming of the complex IV PCA pumps.
About ARX-01, the Sufentanil NanoTab PCA System
ARX-01 is a pre-programmed, non-invasive, handheld system that allows post-operative patients to self-dose with sublingual Sufentanil NanoTabs to manage their post-operative pain. The ARX-01 System is designed to address the limitations of IV PCA by offering:
About AcelRx Pharmaceuticals, Inc.
Based in Redwood City, CA, AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX) is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute and breakthrough pain. AcelRx's lead product candidate, the ARX-01 Sufentanil NanoTab PCA System, which is currently in Phase 3 clinical development, is designed to solve the problems associated with post-operative intravenous patient-controlled analgesia which has been shown to cause harm to patients following surgery because of the side effects of morphine, the invasive IV route of delivery and the inherent potential for programming and delivery errors associated with the complexity of infusion pumps. AcelRx has two additional product candidates which have completed Phase 2 clinical development: ARX-02 for the treatment of cancer breakthrough pain, and ARX-03 for providing mild sedation, anxiety reduction and pain relief for patients undergoing painful procedures in a physician's office. A fourth product candidate, ARX-04, is a sufentanil product for the treatment of moderate-to-severe acute pain that is expected to enter Phase 2 clinical development in the first quarter of 2012 under a grant from the US Army Medical Research and Material Command.
