BMB-101 in Absence Epilepsy and DEE

An Open-Label Phase 2 Study to Evaluate the Efficacy, Safety and Tolerability of BMB-101 in Adults With Either Classic Absence Epilepsy (With or Without Eyelid Myoclonia (EEM; Jeavons Syndrome), OR Developmental Epileptic Encephalopathy (DEE).

BMB-101 in Absence Epilepsy and DEE (NCT06401538) is a Phase 2 interventional studying Absence Epilepsy and Jeavons Syndrome, sponsored by Bright Minds Biosciences Pty Ltd. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The study is a pilot, open-label, study to test whether BMB-101 is safe and effective in reducing the frequency of seizures in subjects with Absence Epilepsy including Epilepsy with Eyelid Myoclonia (also called Jeavons Syndrome) as well as Developmental Epileptic Encephalopathies such as Dravet and Lennox Gastaut. The study will last up to 6 months. There will be a 1 month screening period, then up to 3 months on open-label BMB-101 including titration and tapering/washout periods, and then a 1 month follow-up period. There will be 6 clinic visits.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Absence Epilepsy and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 20 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Subjects must have a diagnosis of Absence Epilepsy with or without eyelid myoclonia (Jeavons Syndrome) or a diagnosis of Developmental and Epileptic Encephalopathy (DEE) such as Dravet syndrome or Lennox-Gastaut syndrome or other DEE. 2. Subjects with Absence must experience at least 4 episodes of 3-4/second SWD lasting at least 3 seconds each in a 24 hour EEG during the baseline period. Those with DEE must have a typical EEG pattern for DEE on routine EEG and experience at least 4 seizures during the 4 week baseline period prior to BMB-101 administration. 3. Subjects can be male or female ages 18-65 inclusive at time of baseline. 4. Subject must have tried at least one anti-seizure medication at a recommended dose and duration and must be on a stable dose on their current anti-seizure medications for at least 4 weeks prior to baseline and remain stable throughout the study. 5. Subjectis willing and able to be compliant with diary completion, visit schedule, and study drug accountability. 6. Female subjects of childbearing potential must have a negative urine pregnancy test at baseline. Subjects of childbearing or child-fathering potential must be willing to use medically acceptable forms of birth control, which includes abstinence, while in this study and for 90 days after the last dose of study drug. Who Should NOT Join This Trial: 1. Subject has current or past history of cardiovascular or cerebrovascular disease, such as cardiac valvulopathy, pulmonary hypertension, myocardial infarction or stroke, or clinically significant structural cardiac abnormality. 2. Subject has moderate or severe hepatic impairment. Asymptomatic subjects with mild hepatic impairment (elevated liver enzymes \< 3x upper limit of normal (ULN) and/or elevated bilirubin \<2x ULN) may be entered into the study after review and approval by the Medical Monitor in conjunction with the sponsor, in consideration of comorbidities and concomitant medications. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
