Purpose

This clinical trial is designed to test whether a single stereotactic intracerebral administration of inhibitory nerve cells into subjects with drug-resistant mesial temporal lobe epilepsy is safe (frequency of adverse events) and effective (seizure frequency).

Seizure frequency averages ≥2 per 28-day period over the 6 months prior to screening.

Exclusion Criteria

  1. Epilepsy due to other and/or progressive neurologic disease 2. Significant other medical condition which would impair safe participation 3. Primary or secondary immunodeficiency 4. Suicide attempt in the past year 5. Severe psychiatric disorders 6. Chronic indwelling intracranial device 7. MRI indicating potential malignant lesion 8. Pregnancy, or currently breastfeeding

This is a two-stage study. Stage 1 is open-label and unmasked. Stage 2 is masked with participant, part of investigator team, and outcomes assessor masked to treatment assignment.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
NRTX-1001 (Stage 1)
Up to 10 subjects.
  • Biological: NRTX-1001
    Biological: NRTX-1001 is an experimental neural cell therapy product candidate derived from an allogeneic human embryonic stem cell line. The stem cells were converted into inhibitory nerve cells that produce GABA.
    Other names:
    • GABA-secreting interneurons
Experimental
NRTX-1001 (Stage 2)
Up to 20 subjects.
  • Biological: NRTX-1001

Detailed Description

Subjects will undergo a single stereotactic intracerebral administration of neural cells, called interneurons, that secrete the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). Subjects will then take medicines to partially suppress their immune system (aimed to prevent the body from rejecting the cells) for 1 year. Safety, tolerability, evidence of neural cell viability and local inflammation (using MRI scans of the brain), and effects on epilepsy disease symptoms will be assessed for 2 years post-transplant. Subjects will be followed for an additional 13 years with quarterly phone contact and annual visits.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
