Marvel Biosciences Initiates Formulation Development with Catalent

Calgary, Alberta--(Newsfile Corp. - April 6, 2022) - Marvel Biosciences Corp. (TSXV: MRVL) and its wholly owned subsidiary, Marvel Biotechnology Inc. (collectively the "Company" or "Marvel"), is pleased to announce that has initiated its pre-clinical oral formulation studies for its lead compound MB-204 with Catalent, Inc.

Catalent, one of the world's largest contract research organizations, has begun development of novel solid amorphous dispersion formulations of MB-204, the Company's novel adenosine A2a receptor antagonist. A new formulation could allow for the administration of even lower doses of the drug and further improve the safety of the product.

"Having a formulation ready for pre-clinical toxicology and clinical trials is another vital milestone the company needs to achieve in order to conduct its first-in-human studies," said Dr. Mark Williams, Chief Science Officer of Marvel. "Catalent is a world-class company with deep expertise in this area, and we look forward to working with them on this project."

Marvel's lead compound asset, MB-204 ("MB-204"), is being developed to help treat neurological conditions such as depression and anxiety, Alzheimer's, ADHD and NASH. Marvel's compound is a novel patented fluorinated derivative of the US-FDA approved Parkinson's disease drug Istradefylline (Nourianz®). Both Istradefylline and MB-204 are highly active derivatives of caffeine, which act as antagonists of the adenosine A2a receptor ("A2aR"). Caffeine is the most widely consumed psychoactive drug in the world and has been associated with a reduced risk for developing Parkinson's disease, Alzheimer's disease and improving concentration.

About Marvel Biosciences Corp.

Marvel Biosciences Corp., and its wholly owned subsidiary, Marvel Biotechnology Inc., is a Calgary-based pre-clinical stage pharmaceutical development biotechnology company that utilizes a "drug redevelopment" approach to drug development. Historically, when a new class of drug is developed, it is optimized for a particular target, but typically only approved for a specific disease. Often, a new disease is identified which involves the same target, however, pending the remaining patent life, the originally approved drug may not have sufficient time left for it to be commercially viable to be developed for the new disease indication. Marvel develops new synthetic chemical derivatives of the original approved drug for the new disease indication. Patent protection is sought as the new potential asset is developed by the Company. The Company believes the business model results in significantly less risk, cost and time to develop its assets compared to traditional biotechnology companies.

Marvel Biotechnology Inc. has currently developed several new chemical entities, using synthetic chemical derivatives of known, off-patent drugs, that inhibit the A2a adenosine receptor with application to neurological diseases (depression & anxiety, Alzheimer's, ADHD), and the non-neurological conditions of cancer and non-alcoholic steatohepatitis. Marvel is also exploring additional undisclosed targets to expand its asset pipeline.
