Mindset Pharma Announces Strong Confirmation of In Vivo Proof-of-Concept Across Its Entire New Drug Program Portfolio

Toronto, Ontario--(Newsfile Corp. - April 20, 2021) - Mindset Pharma Inc. (CSE: MSET) (FSE: 9DF) (OTCQB: MSSTF) ("Mindset") is pleased to announce, that based on data derived from Mindset's in vivo testing program (i.e. testing in animal subjects) carried out by InterVivo Solutions Inc., the Company has confirmed that the majority of its patent pending compounds across four families of chemical scaffolds are exhibiting favourable effects in vivo in models established as having a high correlation to psychedelic effects in humans.

As a result of the promising data derived from Mindset's in vivo program, the Company has now identified a substantial pool of differentiated proprietary compounds with strong psychedelic effects confirmed in vivo from which to select lead drug candidates to move to investigational new drug-enabling ("IND-enabling") studies. To date, the Company has tested 19 compounds in vivo, and 15 of such compounds have been shown to elicit the head twitch response in mice, which is a well-established behavioural marker of 5-HT2A agonism and is associated with producing a psychedelic effect in humans. Achieving this high success rate in preclinical drug studies is considered by Mindset's management and scientific advisory board as being an extraordinary accomplishment and is reflective of Mindset's drug design and behavioural assessment capabilities. In addition, the consistency between the Company's in vitro and in vivo data is a substantial validation for Mindset's in vitro screening protocols.

Malik Slassi, Mindset's Senior VP of Innovation commented, "We are pleased to see such a consistently high rate of success from our in vivo screening program which has encompassed a range of rodent phenotypic screening to elucidate functional agonist properties at the 5-HT2A receptor studies. As we screen additional compounds from our newer psychedelic drug families, our preclinical studies continue to yield positive results. Mindset is well positioned to select promising lead drug candidates to advance into IND-enabling studies from a strong pool of novel compounds. These include not only Family 1 and Family 2, which are emerging as strong acting psilocybin analogs, but Family 3 and Family 4, which Mindset continues to develop and characterize."

To determine 5-HT2A receptor activity in vivo, the Company has performed mouse head twitch assays, and plans to conduct rat behavioural testing and rat drug discrimination testing. In addition to providing evidence of functional agonist properties at the 5-HT2A receptor, these tests also provide insights into potency, central nervous system penetration, oral bioavailability, duration of action, hallucinogenic properties, as well as some insights into safety. Several of the compounds performed favourably on all of currently tested metrics and are demonstrating promising physical-chemical property profiles for development as oral drugs for central nervous system disorders. Additionally, the Company has confirmed 5-HT2A activity by administering a selective 5-HT2A antagonist, M-100,907, and confirming that it blocks the mouse head twitch response.

James Lanthier, Chief Executive Officer of Mindset, added: "Once Mindset has completed in vivo screening of its compounds, the most promising candidate from each family will be selected as a lead and will then progress into IND-enabling studies. The Company anticipates selecting an initial lead candidate shortly and plans to complete IND-enabling studies by mid-2022."

Management of Mindset wishes to caution readers that any statements regarding its novel psychedelic drug candidate compounds are based on preliminary testing data and the clinical success of such compounds is speculative in nature. For more complete and specific information regarding the Company, its prospects and the risks associated with those prospects, readers should consult the Company's website and other reliable sources.
