NNZ-2591をフェラン・マクダーミッド症候群の小児参加者を対象とした研究
フェラン・マクダーミッド症候群を有する小児参加者を対象とした経口投与NNZ-2591のプラセボとの有効性および安全性を比較検討する第III相ランダム化二重盲検プラセボ対照試験
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.
調査の概要
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.
