What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are NRTX-1001, NRTX-1001, or Sham Comparator. The registry lists allocation as randomized. This clinical trial is designed to test whether a single image-guided intracerebral administration of inhibitory nerve cells, called interneurons (NRTX-1001), into subjects with drug-resistant unilateral mesial temporal lobe epilepsy (MTLE), with or without mesial temporal sclerosis (MTS), is safe (frequency of side effects) and effective (seizure frequency).
They plan to enroll about 88 people at 36 sites. Taking part typically means an infusion or injection of a biologic, a procedure as part of the study plus check-ins.
