A Phase I Clinical Trial of UX-GIP001 in the Treatment of Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy

November 3, 2026 updated by: Shanghai UniXell Biotechnology Co., Ltd

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
