A Phase I Clinical Trial of UX-GIP001 in the Treatment of Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy
A Phase I Clinical Trial to Evaluate the Safety, Tolerability, and Preliminary Efficacy of UX-GIP001 (Human GABAergic Interneuron Progenitor Cells Injection) in the Treatment of Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy
This is a phase I study (Protocol: UX-GIP001-102) investigating UX-GIP001 Injection, a novel cell therapy product consisting of human GABAergic interneuron progenitor cells (GIP), for treating adult patients with drug-resistant unilateral medial temporal lobe epilepsy (MTLE). The primary objective is to assess the safety, tolerability, and preliminary efficacy of UX-GIP001. This is an open-label, single-arm study. All enrolled participants will receive the active investigational cell therapy. Seizure frequency and safety parameters will be evaluated by comparing post-transplant outcomes to pre-transplant baselines.
Descripción general del estudio
Descripción detallada
Participants will receive UX-GIP001 via stereotactic neurosurgery, preceded by and followed with immunosuppressive therapy. The study includes a baseline period for eligibility confirmation and a 24-month follow-up phase involving regular safety assessments, neuroimaging , seizure diary logging, and evaluations of quality of life, cognition, and mood. This pioneering regenerative approach seeks to provide a new treatment strategy for drug-resistant MTLE by addressing the underlying pathophysiology.
