New York and Vancouver, British Columbia, November 6, 2025 - Bright Minds Biosciences Inc. (CSE: DRUG) (NASDAQ: DRUG) ("Bright Minds" or the "Company") today announced the initiation of its Prader-Willi Syndrome (PWS) program, and nomination of BMB-105 as a new clinical candidate. As part of the development program, Bright Minds will commence:
- A Phase 2a (NOVA) study to assess the efficacy, safety and tolerability of BMB-101 for the treatment of patients with PWS. This study is designed as a proof-of-pharmacology study to demonstrate that 5-HT2C agonism will address symptom complex in PWS patients.
- A randomized Phase 1 placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and food effect of BMB-105 in healthy volunteers.
Following completion of the ongoing Phase 2a proof-of-pharmacology study with BMB-101, Bright Minds plans to select and advance a 5-HT2C molecule (BMB-105) as the dedicated compound for the PWS program. This approach will reduce the time to market by approximately one year.
Operational Update for BMB-101 in Absence Seizures (AS) and Developmental and Epileptic Encephalopathies (DEE)
- To date, BMB-101 has been well tolerated, with no drug-related Serious Adverse Events nor any safety signals requiring any protocol adjustments.
- Exposure levels and tolerability achieved are consistent with expectations from Phase 1 study, supporting dose selection for future studies.
- Participation in the open-label extension is proceeding well, with nearly all eligible patients electing to remain on therapy under investigator supervision.
- Top-line data will be released in early January 2026
- The Company is planning a Ph 2/3 in AS and DEE in 2026.
"The initiation of our PWS program and NOVA clinical study are exciting next steps as we continue our development efforts to serve patients with rare diseases," said Ian McDonald, CEO and Co-founder of Bright Minds Biosciences. "The current therapeutic landscape is inadequate. 5-HT2C agonism offers a novel mechanism for PWS by targeting the underlying aspects of the disease. This proof-of-pharmacology clinical study is designed to evaluate BMB-101's utility in addressing both hyperphagia and the behavioral/neuropsychiatric symptoms of PWS. We believe it will pave the way forward for a pivotal study with BMB-105, our dedicated compound, and expedite the development of the drug that aims at directly targeting the pathophysiology of PWS. As we continue to develop our pipeline and extensive portfolio of next-generation serotonergic agents, we believe that our 5-HT2C selective agonists provide a unique approach with the potential to deliver a novel and effective treatment option that PWS patients and their families desperately need."
"We are pleased to host world-renowned experts on PWS who share our passion for discovering improved treatments for this complex and challenging neurodevelopmental disorder," concluded McDonald.
The KOLs will provide an overview of PWS, the unmet medical need and limitations of current treatments, the quality-of-life challenges for patients and their families, and the clinical assessment tools used in drug development.

NOVA Clinical Study Design
The NOVA clinical study is a double-blind, randomized, Phase 2a study lasting up to 16 weeks. There will be a 4-week screening period, during which hyperphagia and PWS-related behavioral testing will establish the presence and degree of PWS symptoms. Following the screening period, participants will be randomized in a 1:1 ratio to either BMB-101 or placebo. Participants will enter into a weekly ascending Maximum Tolerated Dose (MTD) titration phase of 4 weeks followed by a maintenance phase of 8 weeks. There will be 5 clinic visits and 4 telephone visits. Following completion of the maintenance phase, participants at the discretion of the Investigator may elect to continue into an unblinded, open label phase to receive BMB-101 for up to 9 months (extendable beyond that time). Participants who do not elect to continue into the open label phase will be tapered from assigned study treatment over 4 weeks following completion of the maintenance phase.
- Primary Objective:
- To assess the effect of BMB-101 on hyperphagia-related behaviors in patients with PWS.
- Secondary Objectives:
- To assess the effect of BMB-101 on various associated behavioral disorders in PWS.
- To assess the safety and tolerability of BMB-101 in patients with PWS.
- Primary Endpoint:
- Hyperphagia. Change from Baseline in Hyperphagia Questionnaire for clinical trials (HQ-CT) scores over time.
- Secondary Endpoints:
- Hyperphagia. Change from baseline in hyperphagia severity score as measured by the Caregiver Global Impression of Severity (CaGI-S) 7-point scale over time.
- Hyperphagia. Change from baseline in hyperphagia severity score as measured by the Clinician Global Impression of Severity (CGI-S) 7-point scale over time.
- Global Impression. Change from baseline in severity and improvement of PWS disease scores as measured by the Clinician Global Impression of Severity and Improvement (CGI-S and CGI-I) 7-point scale over time.
- Behaviors. Change from baseline in PWS-associated behavioral issues such as symptoms measured by the PWS Profile over time.
About Prader-Willi Syndrome
Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder resulting from abnormal gene expression on chromosome 15. According to the Prader-Willi Syndrome Association USA, the condition affects approximately one in every 15,000 live births. The hallmark feature of PWS is hyperphagia - a chronic, life-threatening condition marked by an unrelenting feeling of hunger, obsessive thoughts about food, an overwhelming drive to eat, and a lack of normal satiety. These symptoms can profoundly affect daily life, placing significant emotional and physical burdens on individuals with PWS and their families. Hyperphagia is associated with serious health risks, including acute complications such as stomach rupture, choking, and accidental death related to food-seeking behaviors, as well as long-term comorbidities such as obesity, type 2 diabetes, and cardiovascular disease.
Individuals with PWS also experience significant neurobehavioral challenges, including emotional dysregulation, compulsivity, temper outbursts, and cognitive impairment, which further impact daily functioning and quality of life. There are no drugs that can adequately address those issues
About BMB-101
BMB-101 is a novel scaffold 5-HT2C Gq-protein biased agonist developed using structure-based drug design. It was explicitly designed for chronic treatment of neurological disorders where tolerance and drug resistance are common issues. Biased agonism at the 5-HT2C receptor is one of its key features and adds another layer of functional selectivity within a well-validated target. BMB-101 works exclusively via the Gq-protein signaling pathway and avoids beta-arrestin activation, which is crucial to minimize the risk of receptor desensitization and tolerance development. In preclinical studies, BMB-101 has demonstrated efficacy in animal models of epilepsy, binge eating, aggression, substance use disorder, and cognitive decline which highlights its potential for the use in multiple neurological and neuropsychiatric disorders, including drug-resistant epilepsy, PWS and others.
In Phase 1 clinical studies, BMB-101 was given to 64 healthy volunteers in a Single Ascending Dose (SAD), Multiple Ascending Dose (MAD) and food-effects study. BMB-101 was demonstrated to be safe and well tolerated at all doses. No Serious Adverse Events (SAEs) were observed, and Adverse Events (AEs) were mild in nature and in line with on-target effects for serotonergic drugs.
An extensive target-engagement study was conducted using both fluid biomarkers (transient prolactin release) and physical biomarkers (Quantitative Electroencephalogram, qEEG). Both methods confirmed robust central target engagement. A qEEG signature typical for anti-epileptic drugs was observed, with a selective depression of EEG power at frequencies observed during epileptic seizures. Furthermore, a potentiation of frontal gamma-power was observed in this study which could indicate the potential for improved cognition.
BMB-101 is currently being evaluated in a Phase 2a study in patients suffering from Developmental and Epileptic Encephalopathies and Absence Seizures.
