Clinical trial for Epileptic Encephalopathy
Official title A First-in-human Study of S230815 in Pediatric Participants With KCNT1-related Developmental and Epileptic Encephalopathy
ClinicalTrials.gov ID: NCT07227857
What this study is testing
What is S230815?
S230815 is an investigational injectable medicine being studied as a potential treatment for a specific type of severe childhood epilepsy.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether S230815 is safe and how it behaves in the body of children with KCNT1 epilepsy.
- Who it's for
- You may be able to join if you are a child with KCNT1 epilepsy confirmed by a genetic test.
- What's involved
- You will take S230815 at different doses. You will have visits for tests and check‑ins. The study is open‑label, so everyone knows they are getting the drug.
- Time commitment
- The study lasts up to 72 weeks, with visits at the start, during dose changes, and at follow‑up times.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
