Study Endpoints

Primary Endpoints

Change from Baseline in Hyperphagia Questionnaire for Clinical Trials scores over time in Prader-Willi Syndrome participants.
16 weeks

The Hyperphagia Questionnaire for Clinical Trials consists of 9 items; each rated on a scale from 0 (no symptoms) to 4 (severe symptoms). The total score ranges from 0 to 36, with higher scores indicating worse hyperphagia symptoms. A score of approximately 13 is associated with moderate to severe hyperphagia, and a score of 22 or greater is associated with severe hyperphagia.

Change from baseline in seizure frequency in DEE subjects
10 weeks

Seizure diary

Change from baseline in the number of generalized spike-wave discharges (GSWD) on the 24 hr EEG in Absence subjects.

Frequently asked questions about BMB-101

What is BMB-101?

BMB-101 is an investigational small molecule being developed by Bright Minds Biosciences Inc. for neurological conditions. It is in Phase 2 clinical development for absence epilepsy and Prader-Willi syndrome. BMB-101 has not been approved by the FDA and remains under clinical study.

What is BMB-101 used for?

BMB-101 is being studied for the treatment of absence epilepsy and Prader-Willi syndrome. Clinical trials are also evaluating it in related epilepsy conditions including Jeavons syndrome, Dravet syndrome, and Lennox-Gastaut syndrome. It is investigational and not approved for any indication.

What does BMB-101 target?

BMB-101 targets the 5-HT2C receptor, a serotonin receptor. By acting on this receptor, the small molecule is designed to modulate serotonergic signaling relevant to neurological conditions such as absence epilepsy and Prader-Willi syndrome. It is currently in Phase 2 development.

Who is developing BMB-101?

BMB-101 is being developed by Bright Minds Biosciences Inc., which trades under the ticker DRUG. The company is advancing the small molecule through Phase 2 clinical trials in neurology indications including absence epilepsy and Prader-Willi syndrome.

What phase is BMB-101 in?

BMB-101 is in Phase 2 clinical development. It is investigational and has not been approved by the FDA. The Phase 2 program includes studies in absence epilepsy and related epilepsy syndromes as well as Prader-Willi syndrome.

What clinical trials is BMB-101 in?

BMB-101 is being evaluated in two Phase 2 trials. NCT06401538 is recruiting participants with absence epilepsy and related developmental and epileptic encephalopathies in Australia. NCT07266324 is a not-yet-recruiting Phase 2 study in adults with Prader-Willi syndrome, also in Australia.
