Study Summary

This study consists of two parts. Part 1 will evaluate the safety, efficacy, and pharmacodynamics of 52-weeks of basmisanil treatment in children and adolescents (aged 2-14 years) with Dup15q syndrome. Part 1 will test the hypothesis that negative allosteric modulation of a GABAA receptor subtype can address excessive receptor function and positively impact core neurodevelopmental disease feature in individuals with Dup15q syndrome. Part 2 is an optional 2-year open-label extension to evaluate long-term safety, tolerability, and to provide supportive evidence of benefit of continued treatment with basmisanil in selected efficacy outcomes.

Primary Outcome

The Vineland-3 is an instrument that measures communication, daily living skills, socialization, and motor skills for those with intellectual and developmental disabilities. Items consist of open-ended questions related to activities and behavior and are scored as 2 = Usually, 1 = Sometimes, and 0 = Never. Items requiring a binary response are scored as 2 = Yes, 0. Standard scores for the adaptive behavior composite range from 20-160; lower scores indicate lower adaptive functioning.
