IntelGenx Corp. and Circ Pharma to Commence Phase 1 Proof-of-Concept Study of CRES Pravastatin, a Novel Low Dose Formulation Containing Pravastatin for the Treatment of Hyperlipidemia

SAINT LAURENT, QUEBEC and DUBLIN, IRELAND--(Marketwire - May 19, 2009) - IntelGenx Corp. (TSX VENTURE:IGX) (OTCBB:IGXT) ("IntelGenx") and Circ Pharma ("Circ"), announced today that they completed the formulation development of CRES Pravastatin (Controlled Release Enhanced Statin), and will enter the clinical development phase in Q2/2009 to initiate the proof-of-concept programme.

This Phase 1 trial is a randomized, single dose, crossover study comparing CRES Pravastatin to conventional Pravachol tablets in normal healthy volunteers. The primary objective of this trial is to evaluate the pharmacokinetics of CRES Pravastatin versus conventional Pravachol tablets.

CRES Pravastatin is the first product in a series of Circ Pharma's controlled release lipid lowering products specifically designed to target the absorption of drug in order to reduce the effective dose and potentially lower the side effects. CRES Pravastatin was formulated using IntelGenx's proprietary VersaTab Tablet Technology. It is intended to control the amount and rate of statin delivered to the liver from the gut and is expected to provide significant benefits compared with standard statin administration, namely increased GI absorption, enhanced lipid-lowering efficacy at low to medium doses, maximal lipid lowering effects without an associated increase in systemic exposure, and decreased variability in plasma bioavailability compared with standard statins.

The product may reach the market as early as late 2012. According to IMS Health, the lipid lowering Market had over $11 billion sales in the US alone during 2008.

Dr. Horst Zerbe, President and CEO of IntelGenx said, "We are extremely pleased with the progress that we are making on this project. The anticipated successful completion of this clinical study will once again confirm IntelGenx's unique expertise in the formulation development of complex drug delivery technologies."

Margot Foynes, Chief Technical Officer of Circ Pharma, added "We are looking forward to moving to this important stage of development of the CRES program, the first statin in a series covered by Circ's broad intellectual property portfolio."
