VANCOUVER, British Columbia, Feb. 27, 2023 (GLOBE NEWSWIRE) — Bright Minds Biosciences Inc. (CSE:DRUG) (NASDAQ:DRUG) (“Bright Minds” or the “Company”), a biotechnology company focused on developing novel drugs for the targeted treatment of neuropsychiatric disorders, epilepsy, and pain, today provided an update on its clinical programs, anticipated upcoming milestones and strategic priorities for advancing its development pipeline of innovative treatments to heal the central nervous system (CNS) and brain through the regulation of serotonin.

“This is an exciting time for Bright Minds, as the company successfully transitions from a discovery to a development organization. We are pleased with the progress of our Phase 1 first-in-human trial of BMB-101 and believe there are large potential market opportunities for the treatment of refractory epilepsies, beyond Dravet syndrome and a host of other indications, such as psychosis and addiction disorders. Through an extensive medicinal chemistry and rational drug design program, Bright Minds has successfully developed 5-HT2C, 5-HT2A and 5-HT2A/2C agonists devoid of 5-HT2B agonism. We are progressing our next-generation psychedelics program and have nominated two clinical candidates. BMB-202, a fast, Cmax driven 5-HT2A agonist for the treatment of depression, is expected to enter a first-in-human trial late this year. The team has put in place a top-tier development organization with clinical, regulatory, manufacturing, and controls functions for future product pipeline investigational new drug submissions in the United States. In addition, last May, we established a scientific advisory board consisting of preeminent physicians and scientists across mental health disciplines whose expertise will serve to aide in the development of our clinical programs,” said Ian McDonald, CEO and Co-founder of Bright Minds Biosciences.

Program Updates and 2023 Milestones

BMB-101:
A highly selective and potent 5-HT2C agonist has entered first-in-human Phase I clinical evaluation. The trial is being conducted in Adelaide, Australia, by CMAX Clinical Research, a clinical trial center specializing in a range of early-phase trials and first-in-human studies.

Three-part study to evaluate the safety, tolerability, pharmacokinetic (PK), and food effect in healthy volunteers is underway.

  • Part 1 – single ascending dose – completed
    • 4 cohorts (6 drug and 2 placebo) – single dose (oral solution)
    • Reached the planned top dose, which approached preclinical exposure limits
    • Well tolerated with predictable PK
    • Most common adverse event was oral paresthesias from liquid formulation
  • Part 2 – food effect – completed
    • 12 subjects – crossover with and without breakfast
    • Well tolerated with and without food
    • Effect of food on BMB-101 levels was relatively small, and therefore BMB-101 can be administered without the need for fasting.
  • Part 3 – multiple ascending dose – cohort 1 complete
    • 4 cohorts (6 drug and 2 placebo) – twice a day dosing for 7 days after meals
    • Study (with results) completes in 2Q 2023

Good Manufacturing Practices (GMP) production completed for BMB-101 drug substance and drug product.

BMB-202:

  • A highly selective 5-HT2A agonist, lead candidate within psychedelic program
  • Expected to enter first-in-human trial in late 2023
  • Dose range finding study completed
  • Ready for Good Laboratory Practice (GLP) toxicology program

Strengthened Leadership Team to Guide Development Organization

  • Appointed Mark A. Smith M.D., Ph.D., as Chief Medical Officer. Dr. Smith is an experienced executive in CNS drug development and has directed more than 50 clinical trials across all stages of development. Dr. Smith brings an extensive background in psychiatry that will guide the clinical implementation of the Company’s next generation 5-HT2A agonists.
  • Appointed Jan Torleif Pedersen, MSc PhD., as Chief Scientific Officer. Dr. Pedersen brings 25+ years of expertise in neuroscience research management and has a proven track record in major pharma drug discovery and development.
  • Appointed David Weiner, MD, to its board of directors as a non-executive director. Dr. Weiner brings extensive experience in the discovery and clinical development of novel therapeutics for neurological, psychiatric and rare diseases.

  • The Company will attend the BIO-Europe Spring Conference to be held in Basel, Switzerland, March 20-22, 2023, and virtually, March 28-30, 2023.

About BMB-101

BMB-101, a 5-HT2C selective and biased agonist, has demonstrated compelling activity in a host of in vitro and in vivo non-clinical tests. Compared to Lorcaserin, BMB-101 exhibits strong Gq signaling coupled with minimal beta-arrestin recruitment. Mechanistically, Serotonin (5-Hydroxytryptamine, 5-HT) is a monoamine neurotransmitter widely expressed in the central nervous system, and drugs modulating 5-HT have made a major impact in mental health disorders. Central 5-HT systems have long been associated with the control of ingestive behaviors and the modulation of the behavioral effects of psychostimulants, opioids, alcohol and nicotine. Results of clinical trials and animal studies indicate that 5-HT2C receptor agonists may have therapeutic potential in the treatment of addiction by decreasing the intake of opioids as well as impulsive behavior that can escalate compulsive drug use.

5-HT2C receptors are considered to be involved in epileptiform activity and its activation is thought to have anticonvulsant properties. In well-established and predictive animal models, BMB-101 demonstrated a significant reduction in both the number and intensity of epileptic seizures and is a promising candidate for the treatment of Dravet Syndrome and other forms of epilepsies. BMB-101 is currently being evaluated in a Phase I trial (NCT 05397041) designed to assess the compound’s safety, tolerability, pharmacokinetics, and food effect in healthy volunteers.

About BMB-202

BMB-202 is a highly selective 5-HT2A agonist with proprietary intellectual property. BMB-202 exhibits a more than 30-fold selectivity over 5-HT2C and more than 500-fold selectivity over 5-HT2B. BMB-202 has shown two-fold superior potency compared to psilocin in vitro. BMB-202 is a fast acting, short duration, Cmax driven compound. We call these fast-on-fast-off compounds with anticipated patient discharge around two hours. BMB-202 exhibits excellent drug-like properties and brain penetrance and has demonstrated antidepressant drug profile in vivo. BMB-202 is the first clinical candidate from an extensive portfolio of selective 5-HT2A and 5-HT2A/2C agonists inspired from natural compound scaffolds.

About Dravet Syndrome

Dravet syndrome is an epilepsy syndrome that begins in infancy or early childhood and can include a spectrum of symptoms ranging from mild to severe. Children with Dravet syndrome exhibit focal (confined to one area) or generalized (throughout the brain) convulsive seizures that start before 15 months of age (often before age one). These initial seizures are often prolonged and involve half of the body, with subsequent seizures that may switch to the other side of the body. These initial seizures are frequently associated with fever. Other seizure types emerge after 12 months of age and can be quite varied. Status epilepticus – a state of continuous seizure requiring emergency medical care – may occur frequently in these children, particularly in the first five years of life. Dravet syndrome affects an estimated 1:15,700 individuals in the U.S., or 0.0064% of the population1. Approximately 80-90% of those, or 1:20,900 individuals, have both an SCN1A mutation and a clinical diagnosis of DS. This represents an estimated 0.17% of all epilepsies. As an area of high, unmet medical need, there currently exist only three FDA-approved medications for the treatment of DS: (1) Fintepla® (fenfluramine), which has a black-box label; (2) Diacomit® (stiripentol) and (3) Epidolex® (cannabidiol).
