PBG BioPharma Inc. Announces the launch of a Phase 2/3 Clinical Trial on its Cannabinoid-based Drug Product ProZ-001 as an Adjunctive Therapy for Acute Bipolar Depression

VANCOUVER, British Columbia, February 27, 2024 – PBG BioPharma Inc. (PBG), a leading phytochemical biopharmaceutical company specializing in developing innovative therapeutical and nutraceutical products, today announced that the University of British Columbia (UBC) is officially launching the Canadian Institutes of Health Research funded Phase 2/3 clinical trial, which will use the company's cannabinoid drug product ProZ-001.

The trial, approved by Health Canada, which will be conducted at multiple sites across Canada, is a randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of PBG’s cannabinoid product ProZ-001 as an adjunctive therapy in patients with Acute Bipolar Depression. The trial will enroll approximately 360 patients, over a period of several years, and is expected to begin enrollment immediately.

Bipolar Disorder is a chronic mental health condition characterized by extreme mood swings, including episodes of mania and depression. It affects millions of people worldwide and can have a significant impact on their quality of life. Despite the availability of some treatment options, there remains a significant unmet need for more effective and well-tolerated therapies.

"Bipolar disorder is a complex condition, with depression often posing the greatest burden for patients,” says Dr. Lakshmi Yatham, professor and head of UBC’s department of psychiatry and the study’s principal investigator. "This trial marks a significant step forward in exploring innovative, much-needed treatments for bipolar disorder.”

Cannabinoid-based products have shown promising results in earlier clinical trials. This trial will build on these results and provide additional data on the safety and efficacy of the product in a larger patient population.

“PBG is committed to unlocking the health and therapeutic benefits of medicinal plants including Cannabis. We are thrilled that our cannabinoid-based drug product Proz-001 is being used in a Phase 2/3 clinical trial conducted by leading medical expert Dr. Yatham and his team at the University of British Columbia and other medical researchers from world class universities across Canada," said Dr. Jacqueline Shan, CEO and President of PBG. “We look forward to working with the clinical investigators to advance this important medical research."
