Brief Summary:
The purpose of this study is to investigate the effect of TAK-935 (OV935) on the frequency of motor seizures for participants with 15q duplication syndrome or CDKL5 deficiency disorder throughout the Treatment Period (Titration and Maintenance).

Condition or disease Intervention/treatment Phase
15q Duplication Syndrome CDKL5 Deficiency Disease Drug: TAK-935 Phase 2

Detailed Description:

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. The overall time to participate in this study is 22 weeks, including 4 to 6 weeks Screening/Baseline Period, 12 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.
