Uno Studio di NNZ-2591 in Partecipanti Pediatrici con Sindrome di Phelan-McDermid
Uno Studio di Fase 3 Randomizzato, in Doppio Cieco, Controllato con Placebo per Investigare l'Efficacia e la Sicurezza di NNZ-2591 Somministrato per via Orale Rispetto al Placebo in Partecipanti Pediatrici con Sindrome di Phelan-McDermid
This Phase 3, randomized, double-blind, parallel-group (2-arm), placebo-controlled, multicenter study will evaluate the efficacy and safety of NNZ-2591 compared to placebo in pediatric participants with Phelan- McDermid Syndrome.

Descrizione dettagliata
After providing informed consent/assent, pediatric participants with Phelan-McDermid syndrome ages 3-12 years of age will enter the 4-week Screening Period and undergo assessments for eligibility, baseline characteristics and symptom severity.
Once eligibility is confirmed, participants will be randomized in a 1:1 ratio to receive either orally administered NNZ-2591 or matching placebo during the 13-week Treatment Period. Subsequently, a 2-week safety follow-up period will occur immediately after the completion of the Treatment Period.
