IntelGenx Corp. (TSX:IGX) (OTCQB:IGXT) (the "Company" or "IntelGenx") today announced that patient enrollment in the ongoing Montelukast VersaFilm® Phase 2a (“BUENA”) clinical trial in patients with mild to moderate Alzheimer’s Disease (“AD”) has reached the halfway mark.

This proof-of-concept study currently includes six clinical research sites with the potential of adding two more sites in the coming month, all of which are expected to enroll a total of approximately 70 patients.

"We are encouraged by the speed with which AD patients are enrolling in this trial following the resumption of our recruiting efforts," said Dr. Horst Zerbe, IntelGenx’s CEO. “We continue to work diligently to improve the recruitment rate even further, and anticipate completing enrollment before the end of 2022.”

About Montelukast VersaFilm®

Montelukast is a leukotriene receptor antagonist that was approved by the U.S. Food and Drug Administration in 1997 for the treatment of asthma and seasonal allergic rhinitis. IntelGenx is working to repurpose Montelukast as a therapeutic to treat neurodegenerative diseases by re-formulating the drug into an oral film-based product. IntelGenx's proprietary VersaFilm® technology is especially suited for special needs patient populations, and the Montelukast VersaFilm® product 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 Phase 1 studies, 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's oral film also crossed the blood-brain barrier, an essential feature for treating degenerative brain diseases.
