IntelGenx Initiates Phase 2A Montelukast Versafilm™ Clinical Trial in Alzheimer’s Patients

January 24, 2018

SAINT-LAURENT, Quebec , Jan. 24, 2018 (GLOBE NEWSWIRE) -- IntelGenx Corp. (TSX VENTURE:IGX) (OTCQX:IGXT) (the "Company" or "IntelGenx") is pleased to announce that it has initiated the Phase 2a proof of concept (“POC”) Montelukast VersaFilm™ clinical trial in Alzheimer’s patients, following clearance of the Clinical Trial Application by Health Canada. IntelGenx retained the services of Cogstate and JSS Medical Research as the Contract Research Organizations to support the Montelukast VersaFilm TM study. Cogstate is currently preparing cognitive testing materials and training for clinical staff and physicians to ensure proper administration of the cognitive testing. Once completed, it will also proceed with data analysis. JSS will monitor clinical trial sites to ensure protocol adherence. Patient screening is expected to begin before the end of Q1 2018.

“Current treatments for Alzheimer’s Disease are limited," said Dr. Horst G. Zerbe , President and CEO of IntelGenx . "Accordingly, we believe that Montelukast has the potential to be a true game-changer and are very excited to commence this trial."

The Phase 2a Montelukast Versafilm™ clinical trial is a randomized, double-blind, placebo controlled POC study that will enroll approximately 70 subjects with mild to moderate Alzheimer’s Disease across eight Canadian research sites. The primary study objectives will be to evaluate the safety, feasibility, tolerability, and efficacy of Montelukast buccal film following daily dosing for 26 weeks.

IntelGenx is working to repurpose Montelukast as a therapeutic to treat neurodegenerative diseases by re-formulating the drug into an oral film-based product. Montelukast has been approved by the U.S. Food and Drug Administration in 1997 for the treatment of asthma and seasonal allergic rhinitis. IntelGenx ' proprietary VersaFilm™ technology is especially suited for special needs patient populations, and the Montelukast VersaFilm™ product therefore offers many distinct advantages over tablets for Alzheimer’s Disease patients, including the avoidance and minimization of first-pass-effects, ease of administration, improved API bioavailability, lower dosing and toxicity, better acceptability and improved compliance.

In a recent Phase 1 study, IntelGenx demonstrated that an oral film formulation of Montelukast is safe and tolerable in healthy subjects, reduces the first-pass-effect and has a 52% higher bioavailability compared to the regular Montelukast tablet, demonstrating a clear advantage of delivering Montelukast via film. IntelGenx ' oral film also crossed the blood-brain barrier, an essential feature for treating degenerative brain diseases.

About Montelukast VersaFilm™ :

Montelukast is used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. Montelukast is a CysLT1antagonist; it blocks the action of leukotriene D4 (and secondary ligands LTC4 and LTE4) on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it. This reduces the bronchoconstriction otherwise caused by the leukotriene and results in less inflammation. IntelGenx ' Montelukast buccal film offers a distinct dosage form that improves bioavailability and removes the need for water intake. The latest formulation successfully demonstrated enhanced bioavailability as compared with the brand tablet in a pilot study.
