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

Korábbi kezelés

• History of status epilepticus in the year prior to screening, as guided by ILAE criteria (Trinka 2015) in the judgement of the PI. A history of cluster seizures is permitted.

Más betegség

• Epilepsy due to other and/or progressive neurologic disease.
• Evidence of seizure focus outside hippocampus (either by seizure semiology or EEG findings).
• MRI indicating potential malignant lesion (low-grade glioma of any type is excluded) in any location or non-malignant potentially epileptogenic lesion outside the hippocampus. Small (<2 cm) non invasive meningioma, remote from the affected temporal lobe, is not exclusionary.
• Seizures of non-focal origin.
• Psychogenic Non-Epileptic Seizures (PNES) within the past 3 years.
• Severe psychiatric disorders.
• Significant other medical conditions which would impair safe participation.

Egyéb

• Primary or secondary immunodeficiency.
• Pregnancy, or currently breastfeeding.
• Suicide attempts in past year.

• Male or female, age 18-75 years.
• Subjects of childbearing potential will use highly effective contraception.
• Proven history of focal seizures of hippocampal origin with bilateral seizure foci confirmed by scalp or intracranial ictal EEG (including confirmation by recordings from responsive neurostimulation [RNS] electrodes when applicable).
• Either
  • bilateral hippocampal sclerosis on MRI (evidenced by increased FLAIR signal intensity in both hippocampi or by visual assessment showing reduced volume compared to normal) or
  • bilateral temporal hypometabolism on 18-Flourodeoxyglucose Positron Emission Tomography (FDG PET) (assessed by visual assessment, comparing temporal regions to frontal/parietal lobe neocortex). In this case, ictal EEG recordings must also include intracranial confirmation.
  • or
  • a combination of unilateral instances of the evidence described in a. and b. (e.g., one side can be evidenced by criterion a. and the other side by criterion b.) MRI or PET scans used for assessment must have been acquired within 3 years of screening.
• Subject has had at least four clinical focal seizures, including at least two clinical focal seizures with objective manifestations, on average, per month for the 6 months prior to screening.
• Subject has previously had adequate (in opinion of investigator) therapeutic trials of at least two Anti-Seizure Medicines (ASMs).
• Current ASM regimen, and doses of other drugs known to affect seizure frequency (e.g., antidepressants), have been stable for at least three months prior to enrollment.
• Subject can converse and read in English or Spanish. Able to participate in required study procedures and provide signed informed consent.
