GRIN Therapeutics
GRIN Therapeutics Trial on the Safety and Efficacy of Radiprodil
The first commercial clinical trial for a medicine targeting GRI Disorders is now recruiting patients.
GRIN Therapeutics is enrolling people for a trial of Radiprodil. Because this molecule has been shown to suppress activation of the NMDA receptor, it could help reduce seizures and other negative impacts arising from gain-of-function GRIN Disorders.
Enrollment is already open in Germany, Italy, Netherlands, Spain, UK, Australia and Canada. GRIN Therapeutics is working with the US Food and Drug Administration to be able to enroll patients in the United States.
This initial study will only be recruiting patients with GRIN-related Disorder with a gain-of-function (GoF) variant of: GRIN1, GRIN2A, GRIN2B, or GRIN2D. The reason the study is limited to individuals with gain-of-function (GoF) variants is because the investigational radiprodil is designed specifically to decrease the overactive signals being sent out by NMDA receptors caused by gain-of-function (GoF) variants.

Who is eligible to participate?
- Age: ≥6 months to ≤12 years, with GRIN gene variants known to result in GoF of the NMDA receptor.
- Cohort 1 must have at least 1 observable motor seizure per week and ≥4 observable motor seizures (generalized or focal) during the prospective 4-week Observation Period and must have failed to obtain adequate seizure control with at least 2 antiseizure medications (ASMs) used at appropriate dose and duration.
- Cohort 2 must have significant behavioral and/or motor symptoms based on caregiver report with a CGI-S score ≥4.
- Participants cannot have had brain surgery, or be on other drugs that suppress the NMDA receptor such as memantine.
- Additional inclusion and exclusion criteria are included on the trial page at ClinicalTrials.gov.
- While clinical trials are an essential part of finding treatments and cures, CureGRIN advises families to consult with their neurologist and/or primary physician, and weigh potential risks and benefits before making a decision on what’s right for their child and family.
