简要总结
This is a clinical research study for an investigational drug called RAP-219 in adult participants with focal seizures. This study is being conducted to determine if RAP-219 is safe and effective in reducing focal seizure frequency.
详细描述
Approximately 312 subjects will be randomized into one of two active treatment groups or placebo in a 1:1:1 randomization ratio (Medium Dosage, Low Dosage and Placebo). After completing the Double-blind Treatment Period, participants will either transition into the RAP-219-FOS-901 long-term safety (open-label extension) study or enter the 8-week post-treatment Follow-up Period of this study.
