UX-GIP001 cell therapy for adults with drug-resistant unilateral mesial temporal lobe epilepsy

An Exploratory Clinical Trial of UX-GIP001 Injection (Human GABAergic Interneuron Progenitor Cells Injection) in Adult Patients With Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy

Early Phase 1 Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT07244328

This treatment will try a one-time transplant of GABAergic interneuron progenitor cells into the affected side of the brain to see if it reduces seizures in adults with drug-resistant unilateral mesial temporal lobe epilepsy.

What this trial studies

This open-label, single-arm early-phase study delivers UX-GIP001, a preparation of human GABAergic interneuron progenitor cells, via stereotactic neurosurgery with perioperative immunosuppression. All participants receive the active cell therapy and outcomes after transplant will be compared to each patient's pre-transplant baseline for seizure frequency and safety. The protocol includes a baseline eligibility period followed by a 24-month follow-up with regular safety assessments, neuroimaging, seizure diary logging, and evaluations of quality of life, cognition, and mood. The main goals are to characterize safety and tolerability and to gather preliminary evidence of seizure reduction.

Who should consider this trial

Good fit: Adults aged 18–75 with unilateral mesial temporal lobe epilepsy who have failed at least two anti-seizure medications, have an average of ≥4 focal seizures per 28 days, are on stable medication doses, and have no major contraindications are ideal candidates.

Not a fit: Patients with bilateral or progressive epilepsies, those with only focal aware seizures, prior epilepsy surgery, severe systemic disease, immunodeficiency, or intracranial implants are unlikely to benefit or are ineligible.

Why it matters

Potential benefit: If successful, this approach could reduce seizure frequency and improve quality of life by restoring local inhibitory circuits as an alternative to resective surgery.

How similar studies have performed: Preclinical animal studies of GABAergic interneuron progenitor transplantation have shown promise for reducing seizures, but human data are very limited and this approach remains early and experimental.
