Brain cell injection aims to tame seizures in Drug-Resistant epilepsy
NCT ID NCT07244328
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests an injection of special brain cells (GABAergic interneuron progenitors) in 6 adults with drug-resistant mesial temporal lobe epilepsy. The goal is to see if the treatment is safe and can reduce seizure frequency. Participants will receive the cell therapy once, and researchers will monitor them for side effects and changes in seizures compared to before treatment.

Key Inclusion Criteria: 1. Age 18-75 (inclusive), male or female. 2. Clinical presentation consistent with unilateral mesial temporal lobe epilepsy (MTLE). 3. Has failed to achieve seizure control despite treatment with at least two anti-seizure medications (ASMs) at recommended or maximally tolerated doses. 4. Average focal seizure frequency ≥4 per 28 days during the 3 months prior to screening. 5. Stable doses of ASMs for ≥1 month prior to enrollment. 6. Patient is in good general health or has stable comorbid conditions, and has adequate organ function. Key Exclusion Criteria: 1. Epilepsy caused by other/or progressive neurological diseases , or patients experiencing only focal aware seizures without observable manifestations. 2. History of epilepsy surgery. 3. History of status epilepticus within 12 months prior to screening. 4. Presence of long-term implants in the skull or intracranial space. 5. Severe systemic disease or dysfunction. 6. Primary or secondary immunodeficiency. 7. History of clear suicidal intent, plan, or behavior within one year prior to screening. 8. Severe psychiatric disorders. 9.
