IntelGenx Announces Successful Pre-Approval Inspection of its Lead Product CPI-300

IntelGenx Corp. (TSX VENTURE:IGX)(OTCBB:IGXT) ("IntelGenx") today announced that Pillar5 Pharma Inc. ("Pillar5") successfully passed a pre-approval inspection by the U.S. Food and Drug Administration (FDA) for IntelGenx' lead product, CPI-300, a novel antidepressant, with a high strength of bupropion hydrochloride (HCl), which is the active ingredient in Wellbutrin XL®.

Pillar5, the contract manufacturing organization ("CMO") selected by IntelGenx for the manufacture of CPI-300, successfully responded to all queries from the FDA for its pre-approval site inspection. As expected, the inspection lasted 4 days and concluded with no Form 483 being issued. Form 483 lists observations made by the FDA representative(s) during the inspection of a facility. Such observations are inspectional observations, and do not represent a final Agency determination regarding a facility's compliance.

"First and foremost, we would like to congratulate Pillar5 on this excellent achievement," said Dr. Horst G. Zerbe, President and Chief Executive Officer of IntelGenx. "We are very excited to have passed another important milestone in our endeavors to bring CPI-300 to market and hopefully make this proprietary product available to patients who suffer from major depressive disorder."

IntelGenx recently submitted its reply to a "Complete Response Letter" issued in February 2010 by the FDA after its review of IntelGenx' New Drug Application (NDA) submission for CPI-300. IntelGenx' reply addressed the two main issues identified by the FDA in the Complete Response Letter, namely the qualification of a commercial manufacturing site and the food effect, which was observed both in CPI-300 and the reference product. FDA has accepted IntelGenx' submission and has established November 13, 2011 as its target action date under the Prescription Drug User Fee Act ("PDUFA").

As announced on May 4, 2010, IntelGenx has an ownership stake in Pillar5, representing 10% of the issued and outstanding shares of Pillar5.
