SAINT LAURENT, QUEBEC--(Marketwire - May 11, 2010) - IntelGenx Corp. (TSX VENTURE:IGX)(OTCBB:IGXT) ("IntelGenx") today announced that it has acquired full rights to, and ownership of, CPI-300, a novel, high strength formulation of Bupropion hydrochloride ("HCl"), the active ingredient in Wellbutrin XL®. CPI-300 would be the only single pill, high strength, formulation of Bupropion hydrochloride on the market. At present, patients requiring a high dosage are prescribed multiples of the lower strengths of HCl tablets.

On May 7, 2010, IntelGenx executed a Project Transfer Agreement ("Agreement") with Cary Pharmaceuticals Inc. ("Cary"), its former development partner, whereby Cary assigned its 50% ownership stake in CPI-300 to IntelGenx. Pursuant to the Agreement, IntelGenx and Cary ("the Parties") have agreed to terminate the Collaborative Agreement entered into in November 2007 and the Parties further agreed that the CPI-300 project will be transferred and assigned to IntelGenx. In addition, Cary has assigned to IntelGenx all rights and interest in the regulatory approvals that Cary has or may have had, including the New Drug Application ("NDA"), and IntelGenx will be responsible for the costs associated therewith. IntelGenx will have full and complete authority with respect to the prosecution and/or amendment of the NDA and the commercialization of the product and/or the technology encompassed in the CPI-300 project. IntelGenx will also assume all obligations to, and responsibility for, the Biovail litigation, including the costs thereof. In addition to certain potential pre-commercialization payments, IntelGenx will pay Cary, upon commercialization of CPI-300, 10% of sales royalties received by IntelGenx and 3% of upfront payments received by IntelGenx should a distribution agreement be signed in the future.

"We are very excited to have acquired full control and ownership of CPI-300 at this critical juncture in the product's development," said Dr. Horst G. Zerbe, President and Chief Executive Officer of IntelGenx. "The manufacturing site change for the product has progressed as planned and engineering scale-up batches at Pillar5 have already been manufactured. In addition, we have a meeting scheduled with FDA in early June to address their complete response letter and clarify the required steps to obtain product approval. Finally, the Markman hearing in respect of the Biovail litigation is also scheduled for early June, and we remain optimistic for a positive outcome. The timing of this acquisition should yield substantial value to the company and its shareholders because we believe it is an excellent product that will become commercialized in the near future."

All contracts previously entered into by the Parties prior to May 7, 2010 have been terminated.
