Acura Pharmaceuticals Announces Update on AVERSION Products

Company's Q2'12 Financial Results Release Rescheduled for Monday, July 30

PALATINE, IL--(Marketwire - Jul 27, 2012) - Acura Pharmaceuticals, Inc. (NASDAQ: ACUR), a specialty pharmaceutical company developing products intended to address medication abuse and misuse, announced today that Pfizer Inc. provided notice on July 26, 2012 that it is exercising its right to terminate the license to three development stage products using Acura's AVERSION® Technology and return such products to Acura. The termination will become effective in 12 months under the terms of our License Agreement with a subsidiary of Pfizer. A fourth product utilizing Acura's AVERSION Technology, OXECTA® (oxycodone hydrochloride) Tablets CII, is being commercialized by Pfizer and Pfizer will retain all rights and obligations to OXECTA under the License Agreement.

The products being returned are oxycodone hydrochloride with acetaminophen, hydrocodone bitartrate with acetaminophen and another undisclosed opioid. The hydrocodone product is the most advanced in development, with a clinical study completed in February 2012, which demonstrated bioequivalence to its reference listed drug. This product also was the subject of a pre-IND meeting held with the U.S. Food and Drug Administration (FDA) in May 2012 in which the FDA agreed to a development program for this product generally consistent with that used for OXECTA.

"We are pleased to regain control of these tamper-resistant opioid products because we continue to believe they hold promise in combating widespread prescription opioid abuse," said Bob Jones, President and Chief Executive Officer of Acura Pharmaceuticals. "We will evaluate our strategy for these products over the coming months, including possible partnering with alternative strategic partners, and will work with Pfizer to exercise our rights under the Pfizer Agreement for the transition of these products back to us."

Acura now plans to report financial results for the second quarter of 2012 following the close of financial markets on Monday, July 30, 2012. The Company will host a conference call on Tuesday, July 31, 2012 at 8:30 a.m. ET to discuss the quarterly results and Pfizer's return of the development products.
