NTE001 Study

A Phase I/II Clinical Trial of NRTX-1001 Nerve Cell Therapy in Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy



NRTX-1001 is an investigational drug (experimental drug). An investigational drug is one that the FDA and other health authorities have not yet approved to be safe and effective.

NRTX-1001 has undergone preclinical laboratory testing and received approval from the FDA to be tested in people.

NTE001 is the name of the clinical study designed to investigate the safety and efficacy of NRTX-1001 as a potential treatment for drug-resistant unilateral mesial temporal lobe epilepsy. Investigational study sites are currently screening adult patients in the United States for participation.

Purpose of the Study

This study is being conducted to gather information about the use of NRTX-1001 to treat seizures in people who have drug-resistant epilepsy. This is the first time NRTX-1001 is being tested in humans.

Epilepsy occurs when nerve cells send out abnormally ‘excited’ signals. A certain neurotransmitter, or messenger in the brain, called Gamma Aminobutyric Acid (GABA) can block or inhibit these excited signals. NRTX-1001 is made from human stem cells that have been developed into a non-dividing type of nerve cell called an interneuron, which releases GABA.

It is hoped that through implantation of NRTX-1001, the interneurons will form connections in the brain, and the release of GABA will quiet the nearby neurons and help limit the abnormally “excited” signals, resulting in fewer seizures.

What is NRTX-1001?

  • NRTX-1001 is made from human stem cells that have been developed into interneurons (like the cells already in the brain).
  • NRTX-1001 cells produce GABA, a neurotransmitter in the brain thought to inhibit seizure activity.

GABAergic interneuron cell therapy may restore missing inhibition and rebalance neural activity.

Qualifying for the Study

Are 18-65 years old

Have focal seizures, clinically defined as Temporal Lobe Epilepsy

Seizures haven’t been controlled by taking at least 2 seizure medications

Seizures confirmed by EEG and MRI to be coming from one location

Seizure frequency is more than 2 per 28 days period over 6 months

Considered to be a candidate for Temporal Lobectomy or Laser Ablation

No prior history of craniotomy

No prior exposure to gene or cell therapy treatments (of any kind)

Study Expenses

Neurona will reimburse the study subject and caregiver for reasonable travel expenses to confirm their eligibility and discuss participation with their doctor.

Once enrolled, they should not have to spend any of their own money to participate in the trial. All study costs are paid for by Neurona, including a service to help coordinate and pay for their travel arrangements.
