成人皮膚筋炎患者におけるエンパシプルバートの身体への影響、血中濃度、有効性、安全性に関する研究 (empacific)
成人皮膚筋炎患者におけるエンパシプルバートの複数回投与レジメンの安全性、忍容性、および有効性を評価するための第2相、無作為化、二重盲検、プラセボ対照、多施設共同研究
This study will evaluate the safety and efficacy of empasiprubart compared with placebo in adult participants with dermatomyositis (DM).
The study duration will be approximately 92 weeks for all participants. After the screening period, eligible participants will be randomized in a 2:1 ratio to receive either empasiprubart or placebo, respectively, during the treatment period (duration of 25 weeks). At the end of the treatment period, all the participants will enter a safety follow-up period (duration of 65 weeks).
