10〜50歳の参加者におけるアデノ関連ウイルスベクター媒介遺伝子治療であるSAR446268の安全性、忍容性、および有効性を調査する研究。 (BrAAVe)
用量エスカレーション(パートA)、および用量膨張(パートB)パーツを伴うフェーズ1/フェーズ2のオープンラベルシングルアーム研究は、非共生性筋膜炎栄養栄養栄養栄養栄養栄養栄養栄養栄養栄養栄養栄養栄養酸栄養型型の参加者10〜50歳の参加者10〜50歳のアデノ関連ウイルスベクター媒介遺伝子治療であるSAR446268の安全性、忍容性、および有効性を評価するための部分を評価します。
This is a Phase 1/Phase 2 open-label single arm, multicenter, and multinational study with SAR446268 for treatment of male and female participants 10 to 55 years old with non-congenital myotonic dystrophy (DM) type 1 (DM1).
The purpose of this study is to evaluate the safety and efficacy of SAR446268 in knocking down dystrophia myotonica protein kinase (DMPK) messenger ribonucleic acid (mRNA) levels and improving neuromuscular function in DM1 participants receiving a single intravenous (IV) administration of SAR446268. The study consists of a dose escalation part (Part A) during which single ascending doses of SAR446268 will be evaluated in 3 distinct cohorts and an optional fourth dose cohort. Once a safe and effective dose is identified, additional participants will be treated in Part B, the dose expansion phase of the study.
The study duration will be 112 weeks (approximately 2 years) for each participant in Parts A and B respectively and includes an optional pre-screening period, approximately 8-week screening phase and a 104-week follow-up period post-SAR446268 administration.
調査の概要
詳細な説明
Each participant meeting the eligibility criteria for each of the study parts will receive a single dose administration of SAR446268.
