Positive Bioequivalence Results for IntelGenx Developed Product

SAINT LAURENT, QUEBEC--(Marketwire - April 20, 2009) - IntelGenx Corp. (TSX VENTURE:IGX)(OTCBB:IGXT) ("IntelGenx") today announced the results of a clinical pilot study for a new antihypertensive product. The results of the study indicate that the product is bioequivalent to a leading antihypertensive product brand. The product has been developed using IntelGenx's proprietary multilayer "Versatab" delivery technology. Versatab provides a patent-protected, cost-effective method of formulating up to three active ingredients in a single dosage form.

On announcing the results Dr. Horst G. Zerbe, President and Chief Executive Officer of IntelGenx, said "We are delighted with these results. This is a significant achievement for IntelGenx that reaffirms our technological capabilities. We are now eager to move forward to the next level of pivotal clinical studies with our partner DAVA Pharmaceuticals."

Scale-up and manufacturing of the pivotal batches will now commence. In addition, it is anticipated that the pivotal bioequivalence study for the product will be conducted later this year. If the results of the study are satisfactory, it would be followed by the submission of an Abbreviated New Drug Application to the United States Food and Drug Administration.

IntelGenx and DAVA Pharmaceuticals Inc. ("DAVA") formed a strategic alliance in March 2008. Under the terms of the alliance, IntelGenx is responsible for product development using its patented proprietary delivery technologies. DAVA is responsible for commercialization and marketing activities in the United States. IntelGenx is entitled to fees for the development of the product, as well as a share of DAVA's gross profit from any product sales in the United States. According to IMS Health, peak sales for the leading antihypertensive product brand exceeded $1.5 billion in the United States in 2007.
