SAINT LAURENT, QUEBEC, - June 23, 2009 - IntelGenx Corp. (IGX)(U.S.:IGXT) ("IntelGenx") today announced that the New Drug Application filing for their antidepressant CPI-300 has been accepted by the U.S. Food and Drug Administration (FDA) for standard review. Pursuant to Prescription Drug User Fee Act (PDUFA) guidelines, IntelGenx expects the FDA will complete its review or otherwise respond to the NDA by February 6, 2010.

“Formal FDA acceptance of the NDA clears the path towards review and approval of CPI-300 within the timeframe expected” said Dr. Horst G. Zerbe, President and Chief Executive Officer of IntelGenx. “We are especially pleased to note that the FDA has confirmed that our NDA was sufficiently complete to permit a substantive review. As CPI-300 represents our very first NDA, this is not only a testament to the expertise of our staff but also to the strength of our partners.”

IntelGenx and Cary Pharmaceuticals Inc. entered into a Collaborative Agreement in November 2007 to jointly develop and commercialize CPI-300 using IntelGenx’s proprietary oral delivery technology. Under the terms of the Collaborative Agreement, IntelGenx raised $2 million in March 2008 to fund completion of the product development and Cary Pharmaceuticals Inc. acted as the applicant for the submission of the NDA. Upon commercialization of the product, IntelGenx and Cary Pharmaceuticals Inc. would share profits.

CPI-300 was formulated using IntelGenx’s proprietary controlled release technology. It contains a new strength of a widely prescribed antidepressant. CPI-300 was developed to broaden the dosing options for physicians while providing a more convenient dosing option for patients requiring a higher strength of the products currently available. It will be indicated for the treatment of major depressive disorder.
