Clearmind Medicine Signs Agreement to Examine MEAI in Combination and Sequencing with Tirzepatide Against Blockbuster GLP-1 Medications

Vancouver, Canada, May 18, 2026 (GLOBE NEWSWIRE) -- Clearmind Medicine Inc. (Nasdaq: CMND) (“Clearmind” or the “Company”), a clinical-stage biotech company focused on the discovery and development of novel, non-hallucinogenic, second-generation, neuroplastogen-derived therapeutics to solve major under-treated health problems, today announced the signing of a new research agreement with Yissum Research Development Company of the Hebrew University of Jerusalem Ltd. The agreement will fund a comprehensive preclinical study evaluating the metabolic efficacy of MEAI (CMND-100), both in combination with and as a maintenance therapy following tirzepatide treatment in diet-induced obese (“DIO”) mice. The research will be conducted by Professor Joseph (Yossi) Tam and his team at the Obesity and Metabolism Laboratory at the Institute for Drug Research, School of Pharmacy, Hebrew University of Jerusalem.

The global market for incretin-based therapies and tirzepatide has grown into a massive industry valued at approximately $50–66 billion in 2025, and is projected to reach $170–185 billion by 2033. These therapies have significantly advanced the treatment of obesity and type 2 diabetes, delivering substantial weight loss and cardiometabolic improvements. Despite their remarkable success, GLP-1 and dual GLP-1/GIP receptor agonists primarily work by suppressing appetite and reducing energy intake. A major clinical challenge remains: substantial weight regain- often 25% or more of the lost weight within one year, along with partial reversal of metabolic benefits, frequently occurs upon discontinuation. This underscores the urgent need for complementary or maintenance strategies that can enhance treatment durability, help preserve lean muscle mass, and actively boost energy expenditure.

Building on positive results from its prior collaboration with Professor Yossi Tam’s laboratory at the Hebrew University, where MEAI demonstrated approximately 15–20% body weight reduction in DIO mice, primarily through increased energy expenditure and fat utilization while preserving lean mass and improving glucose homeostasis and hepatic steatosis, Clearmind is now advancing MEAI into combination and sequencing strategies with today’s leading incretin therapy.

The new 12-month study, titled “Assessing the Metabolic Efficacy of MEAI in Combination and Sequencing with Tirzepatide in Diet-Induced Obese Mice,” will examine: Additive or synergistic effects when MEAI is administered concomitantly with tirzepatide and the potential of MEAI as a maintenance therapy to attenuate post-tirzepatide weight regain and preserve metabolic benefits across multiple doses.

“MEAI is designed to offer a differentiated mechanism that potentially complements incretin therapies,” said Dr. Adi Zuloff-Shani, Ph.D., Chief Executive Officer of Clearmind Medicine. “While those drugs excel at reducing food intake, our previous preclinical data show MEAI significantly enhances energy expenditure. We believe that this combination and maintenance approach has potential to deliver more robust, durable, and clinically meaningful outcomes for patients.”
