简要总结
This is a clinical research study for an investigational drug called RAP-219 in patients with Refractory Focal Epilepsy. This study is being conducted to determine if RAP-219 works and is safe in patients with Refractory Focal Epilepsy.
详细描述
This is a Phase 2A, proof-of-concept, multi-center, open-label study designed to evaluate the efficacy, safety, tolerability, and PK/PD relationship of RAP-219 in adult participants with refractory focal epilepsy. The activity of RAP-219 will be assessed in approximately 30 participants treated with the RNS® system.
