Testing a new seizure medication for children with severe epilepsy

This trial is testing a new medication called Relutrigine to help children and young people with developmental and epileptic encephalopathy (a severe form of epilepsy that affects development). The study will compare the medication to a placebo (a dummy pill with no active ingredient) to see if the medication is safe and can reduce seizures.

Severe childhood epilepsy can be very difficult to control with existing treatments, and children with this condition often continue to have seizures despite trying multiple medications. This trial is testing whether this new treatment option can help reduce seizures and improve safety in this group.
