Presentation at the American Epilepsy Society Annual Meeting will also highlight proposed design of planned Phase 3 study of radiprodil in children with gain-of-function variants

NEW YORK, Nov. 21, 2024 /PRNewswire/ -- GRIN Therapeutics Inc., a leader in development of therapies to treat serious neurodevelopmental disorders, today announced that it will present findings from the company's Phase 1b Honeycomb clinical trial assessing the effects of radiprodil, the company's investigational GluN2B negative allosteric modulator, in the treatment of GRIN-related neurodevelopmental disorder with gain-of-function (GoF) variants. The poster presentation, to be held at the American Epilepsy Society's (AES) Annual Meeting, December 6-10 in Los Angeles, CA, will also include a review of the proposed design of the planned Phase 3 clinical trial for radiprodil scheduled to initiate in early 2025.

Presentation Details:

Title: Pharmacokinetics, Safety/Tolerability, and Effect on Seizure Frequency and Behavior of Individually Titrated Radiprodil Doses in Children with GRIN-Related Disorder: Topline Multicenter Study Data
Presenter: Pierandrea Muglia, MD, Founder, GRIN Therapeutics
Session date/time: Saturday, December 7, 12:00 – 6:00pm PST

About Radiprodil:

Radiprodil is an investigational, selective and potent negative allosteric modulator of the N-methyl-D-aspartate (NMDA) receptor subtype 2B (NR2B or GluN2B). In nonclinical studies, radiprodil has been shown to potently and selectively modulate NMDA NR2B or GluN2B. Radiprodil has also demonstrated an antiseizure effect in a number of in vitro and in vivo preclinical seizure and epilepsy models and specifically in models characterized by an enhanced GluN2B-NMDA transmission, which can occur with gain-of-function (GoF) mutations in GRIN-related neurodevelopmental disorder. In vitro analysis of brain tissues extracted from both tuberous sclerosis complex (TSC) and focal cortical dysplasia (FCD) lesions has shown enhanced GluN2B-NMDA expression supporting the potential ability of radiprodil to control seizures in these conditions.
