Acurox NDA Accepted for Filing With a Priority Review Classification

Acurox Tablets New Drug Application Accepted for Filing With a Priority Review Classification

PALATINE, ILLINOIS and BRISTOL, TENNESSEE, March 3, 2009 – Acura Pharmaceuticals, Inc. and King Pharmaceuticals, Inc. (the Companies) today announced that Acura’s New Drug Application (NDA) for Acurox (oxycodone HCl/niacin) Tablets was accepted for filing by the US Food and Drug Administration (FDA) with a Priority review classification. Acurox is an immediate release opioid analgesic, has a proposed indication for relief of moderate-to-severe pain and is designed to deter common methods of misuse and abuse.

The user fee goal date under the Prescription Drug User Fee Act (PDUFA) is June 30, 2009. The FDA's timelines described in the PDUFA guidance are flexible and subject to change based on workload and other potential review issues.

About Priority Review Classifications

The FDA may grant an NDA a Priority review classification if its assessment of conditions and information available at the time the application is filed indicates the drug product has the potential to provide, among other things, significant improvements compared to marketed products. A Priority review classification by the FDA determines an NDA’s review timeline under PDUFA and is not intended to predict a drug's market acceptance or sales potential. If the Acurox Tablets NDA is ultimately approved by FDA, for which no assurances can be provided, the Companies believe Acurox Tablets will be the first approved immediate release opioid analgesic designed to deter the most common methods of opioid misuse and abuse. According to the National Survey on Drug Use and Health published by the Substance Abuse and Mental Health Services Administration in 2006, immediate-release opioids were abused approximately 10 times more frequently than extended-release opioids.1

Expectations for Acurox Tablets Product Labeling

The FDA has indicated that an explicit claim of abuse deterrence requires the demonstration of an actual reduction in product abuse by patients or drug abusers in routine clinical practice, after approval. The FDA has stated that information describing the physical characteristics of a product candidate and/or the scientifically derived results of laboratory and clinical studies simulating product abuse may be acceptable to include in the product label. The Companies have included in the proposed label in the Acurox Tablets NDA both a physical description of the abuse deterrent characteristics of Acurox Tablets and information from a number of laboratory and clinical studies designed to simulate the relative difficulty of abusing product candidates utilizing Acura's Aversion Technology. The extent to which such information will be included in the FDA approved product label will be the subject of discussions with and agreement by the FDA as part of the Acurox Tablets NDA review process. There can be no assurance that the proposed label for Acurox Tablets will be approved by the FDA.
