Acurox® with Niacin (oxycodone HCl/niacin) TabletsWe and King are analyzing the results from study AP-ADF-114 (Study 114), an abuse liability study comparing the like/dislike scores of Acurox® with Niacin Tablets to oxycodone HCl tablets alone. Study 114 was not included in the original NDA filing for Acurox® with Niacin Tablets submitted to the FDA in December 2008 and for which we received an FDA Complete Response letter in June 2009. We intend to complete our Study 114 analyses and submit a response to the FDA's June 2009 Complete Response letter for Acurox® with Niacin Tablets. All of our opioid product candidates utilizing Aversion® Technology (with or without niacin) are encompassed by two issued U.S. patents, which in combination with our anticipated product labeling and drug product listing strategies are anticipated to provide our opioid products licensed to King with protection from generic competition through the expiration of our patents in 2025.
