|Condition or disease||Intervention/treatment||Phase|
|15q Duplication Syndrome CDKL5 Deficiency Disease||Drug: TAK-935||Phase 2|
The drug being tested in this study is called TAK-935 (OV935). TAK-935 is being tested to treat people with 15q duplication syndrome or CDKL5 deficiency disorder. This study will assess the effects of TAK-935 on seizure frequency, safety.
The study will enroll approximately 30 participants. Participants will be enrolled into 2 groups based on their diagnosis as: 15q duplication syndrome or CDKL5 deficiency disorder.
All participants will be asked to take TAK-935 tablets twice daily with or without food.
The study comprises of 2 periods: Screening/Baseline Period and Treatment Period (Dose Optimization and Maintenance). The overall time to participate in this study approximately 30 weeks, including 4 to 6 weeks Screening/Baseline Period, 20 weeks Treatment Period, 2 weeks Taper, and 2 weeks safety follow up period. Participants completing this study will have an option to enroll in the open-label extension (OLE) study, under a separate protocol.
