The Clinical Research Landscape of Pediatric Drug-Resistant Epilepsy.

OBJECTIVE:To characterize the clinical research landscape of pediatric drug-resistant epilepsy (DRE) with a focus on neurotechnology. METHOD:We searched the ClinicalTrials.gov registry using the terms "epilepsy" and "drug resistant" for studies including participants age 0-17 years. Returns were grouped by intervention (eg, neurotechnological, drug). Key trial features such as age range, trial status and outcomes were compared across interventions. RESULTS:We identified 101 registered trials with pediatric DRE patients. Thirty-two (32%) investigate neurotechnological interventions, devices, or diagnostic procedures; 13 (41%) are currently active. Among neurotechnology trials, 15 (46%) investigate vagus nerve stimulation, transcranial direct current stimulation, or deep brain stimulation; few are specific to children. Of the remaining 69 trials, 37 investigate a drug, 17 investigate a dietary therapy, and 15 investigate another intervention. Seizure frequency is the most frequent primary outcome measured in the trials identified. SIGNIFICANCE:The landscape of registered trials pertaining to pediatric DRE reflects a lag between clinical research and clinical practice, and highlights the need for timely evidence before novel neurotechnological interventions are widely adopted into clinical practice.
