REDWOOD CITY, Calif., Sept. 22, 2015 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX) (AcelRx) announced today that the European Commission (EC) has approved Zalviso™ (15 micrograms sufentanil sublingual tablets) for the management of acute moderate-to-severe post-operative pain in adult patients. The marketing authorization is granted for the 28 EU member states as well as for the European Economic Area (EEA) countries, Norway, Iceland and Liechtenstein. Zalviso is a system combining a drug and a device designed to deliver a sublingual tablet formulation of sufentanil 15 mcg via a proprietary, pre-programmed, non-invasive, patient-controlled analgesia (PCA) device. Grunenthal Group, AcelRx's licensee in Europe and Australia, expects the product to be available to Western European patients in the first half of 2016.
"This is a significant event for AcelRx. Not only is this the Company's first marketing approval, but it represents the successful development and commercialization of a product that we believe will provide a new way for physicians and their patients to treat acute moderate-to-severe post-operative pain using an innovative delivery method," stated Howie Rosen, interim chief executive officer of AcelRx Pharmaceuticals. "Our partner Grunenthal will be working with the member states of the EU and EEA to ensure that Zalviso is made available to those patients who would benefit from an effective and reliable solution for their moderate-to-severe post-surgical pain."
Zalviso is designed to offer sustained (for up to 72 hours) and reliable pain relief for acute moderate-to-severe post-operative pain. In a Phase 3 clinical trial in patients who had undergone major joint replacement or open abdominal surgery, a higher percentage of study participants who self-administered Zalviso over a 48-hour period rated the method of pain control "good" or "excellent" compared to those using intravenous (IV) morphine PCA (p=0.007). Moreover, patients surveyed in this study rated their overall ease of care (p<0.001) and overall satisfaction (p=0.004) with Zalviso as higher than with IV morphine PCA. Zalviso was also rated by nurses to provide higher treatment satisfaction (p<0.001) and overall ease of care (p=0.017) compared with IV morphine PCA. Adverse events reported in the study were generally mild or moderate in nature and similar in both placebo and treatment groups, however fewer patients using Zalviso™ experienced oxygen desaturation episodes < 95% (p=0.028).
Dott. Alberto Grua, chief commercial officer Europe, Australia, North America & Global Product Supply (CCO EU, AUS, NA & GPS) from Grunenthal, adds, "We are delighted to bring a new, innovative way to manage post-operative pain to European healthcare professionals and patients. By combining the benefits of patient-controlled analgesia with those of a non-invasive route of administration, Zalviso offers a unique solution to address unmet needs of adult patients suffering from acute moderate-to-severe post-operative pain."
On an annual basis, there are 19 million surgical procedures with associated acute moderate-to-severe post-operative pain in the European Union. A recent German survey in patients after surgery has shown that 55% of all patients are not satisfied with their treatment for post-operative pain1. Even more so, 30% mention that their pain management has been inadequately effective [1 Maier C et al. Dtsch Arztebl Int. 2010; 107; 607-614].
Zalviso is an innovative pre-programmed, non-invasive, handheld system that allows hospital patients with acute moderate-to-severe post-operative pain to self-dose with sufentanil sublingual tablets, 15 mcg, to manage their pain. The system is designed to help address certain problems associated with post-operative analgesia, such as the drug-related side effects and delayed analgesic effect of morphine, the invasive intravenous (IV) route of delivery of current systems for patient-controlled analgesia (PCA) and the complexity of infusion pumps used for IV PCA delivery.
Grunenthal holds the rights for Zalviso in Europe and Australia while AcelRx retains all rights in North America, Asia, Latin America and Middle East/Africa. Under the terms of the collaboration, Grunenthal is responsible for maintaining the regulatory approval for the drug product and all commercial activities for Zalviso, in the Grunenthal territory. AcelRx will be responsible for maintaining device regulatory approval in the Grunenthal territory, as well as manufacturing and supply of Zalviso to Grunenthal for commercial sales and clinical trials.

ARX-04 delivers 30 mcg sufentanil sublingual, a high therapeutic index opioid, through a disposable, pre-filled, single-dose applicator (SDA). AcelRx has reported positive results from the pivotal Phase 3 SAP301 ambulatory surgery study, and will be advancing ARX-04 into a study in emergency room patients in 2015.
