Een onderzoek naar het effect van Empasiprubart op het lichaam, de bloedspiegels, de effectiviteit en de veiligheid bij volwassenen met dermatomyositis (empacific)
Een fase 2, gerandomiseerde, dubbelblinde, placebogecontroleerde, multicentrische studie om de veiligheid, verdraagbaarheid en werkzaamheid van meervoudige dosisregimes van Empasiprubart bij volwassenen met dermatomyositis te evalueren
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).
