INTELGENX ANNOUNCES FIRST PARKINSON'S DISEASE PATIENTS DOSED WITH MONTELUKAST VERSAFILM(TM) IN PHASE 2 'MONTPARK' CLINICAL TRIAL

IntelGenx Corp.'s Montelukast VersaFilm has been administered to the first Parkinson's disease (PD) patients in the phase 2 clinical trial.

Montpark (EudraCT No. 2023-504278-39-00) is a phase 2, randomized, double-blind, placebo-controlled, parallel-arm, multicentre trial that will investigate the efficacy of oral high-dose Montelukast on the progression of early-to-moderate PD. The study will enroll up to 90 patients who will receive 30-milligram (mg) Montelukast VersaFilm or placebo twice daily for 18 months, followed by a three-month washout period. Eligible candidates must be on levodopa treatment at the time of enrolment and may also be on other dopaminergic symptomatic agents. Montpark is being conducted at the Karolinska University Hospital and at three other Swedish University-affiliated institutions under IntelGenx's previously announced research collaboration with Per Svenningsson, MD, PhD, who is serving as the study's lead principal investigator.

"Dosing of the first PD patients in the phase 2 Montpark trial represents a major milestone in the clinical development of Montelukast VersaFilm, which is also being investigated for the treatment of mild to moderate Alzheimer's disease, or AD, in the ongoing Buena phase 2a study," said Dwight Gorham, IntelGenx's chief executive officer. "As treatment options for neurodegenerative diseases like PD and AD remain limited, with studies such as Montpark and Buena, we are taking significant steps closer to providing patients with a novel, disease-modifying treatment that also offers a dosing method that is especially suited to their needs."

About Parkinson's disease

PD is the second-most-common neurodegenerative disease after AD, with an estimated nine million patients globally and one million patients in the United States. In the United States, it is estimated that 90,000 new patients will be diagnosed with PD every year. No neuroprotective or disease-modifying treatments are currently available. The current standard treatment of PD motor dysfunction is based on the enhancement of dopaminergic transmission and involves the administration of L-dopa. Evidence from multiple patient studies and animal models has shown a significant immune component during the course of the disease, highlighting immunomodulation as a potential treatment strategy. Montelukast is a CysLT1 antagonist which decreases neuroinflammation by inhibiting CysLT1.

About Montelukast VersaFilm

Montelukast 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, such as PD and AD, by reformulating 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 PD and AD patients, including the avoidance and minimization of first-pass effects, ease of administration, improved API (active pharmaceutical ingredient) 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 per cent higher bioavailability compared with 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.
