A Phase 1/2 Study of NRTX-1001 Neuronal Cell Therapy in Drug-Resistant Bilateral Mesial Temporal Lobe Epilepsy (MTLE)

This is a multicenter, single arm, open label clinical trial that is designed to test the safety and preliminary efficacy of single administration inhibitory nerve cells called interneurons (NRTX-1001), into both temporal lobes of subjects with drug-resistant bilateral mesial temporal lobe epilepsy.

This is a multicenter, single arm, open-label study of NRTX-1001 in subjects with drug-resistant bilateral MTLE, with the objective of evaluating safety and preliminary efficacy in reducing seizure frequency. The subjects will undergo a single stereotactic CT or MRI-guided intracerebral administration of human interneurons into both temporal lobe regions of the brain. NRTX-1001 secretes the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), which is intended to suppress the onset and spread of the seizures. Safety, tolerability, and effects on epilepsy disease symptoms will be assessed at approximately quarterly intervals for 2 years after the administration of NRTX-1001. After the two-year period, subjects will be followed with quarterly phone calls and annual visits in years 3 through 15.
