Efficacy and Safety of Fecal Microbiota Transplantation for Epilepsy

PHASE2; PHASE3 · The Second Hospital of Nanjing Medical University · NCT02889627

What this trial studies

This clinical trial evaluates the efficacy and safety of fecal microbiota transplantation (FMT) as a treatment for epilepsy. Patients diagnosed with epilepsy will receive repeated FMT from healthy donors while maintaining their current antiepileptic medication regimen. The primary outcome measure is the frequency of seizures, while secondary outcomes include the 50% response rate to treatment. The study aims to explore the potential benefits of gut microbiota on neuropsychiatric disorders, particularly epilepsy.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with epilepsy for at least three months who have experienced seizures during the preceding three months.

Not a fit: Patients with severe comorbid conditions or those who have undergone previous fecal microbiota transplantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce seizure frequency in patients with epilepsy.

How similar studies have performed: While few studies have explored the use of microbiota for brain diseases, this approach is relatively novel and has not been extensively tested in the context of epilepsy.
