詳細な説明
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.
