  • Research summary

    This is an open-label, multicenter, phase 1b study in pediatric participants with GRIN related disorders. The participants will be split into 1 of 2 groups: participants with drug-resistant seizures (with or without behavioral symptoms) or participants with behavioral symptoms (but no qualifying seizures). The study will consist of 2 parts; a dose escalation part (Part A) to determine the safety, tolerability, and pharmacokinetics of different doses of radiprodil, and a long-term follow-up period (Part B) to assess the treatment effect on seizures and behavioral symptoms. \nThe study aims to find a safe and well tolerated dose after approximately 8 weeks of continuous treatment during Part A. Initial signs of efficacy and changes in quality of life will also be evaluated. \nThe study will further evaluate the long-term safety and tolerability of radiprodil and assess the maintenance of the treatment effect during Part B.\nThis study will enroll approximately 24 participants in the EU, UK and North America.
