Une étude de l'effet de l'Empasiprubart sur le corps, les taux dans le sang, l'efficacité et l'innocuité chez les adultes atteints de dermatomyosite (empacific)
Une étude multicentrique de phase 2, randomisée, en double aveugle, contrôlée par placebo, pour évaluer l'innocuité, la tolérabilité et l'efficacité de schémas thérapeutiques à doses multiples d'empasiprubart chez les adultes atteints de dermatomyosite
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).
