En studie av Empasiprubarts effekt på kroppen, nivåer i blodet, effektivitet och säkerhet hos vuxna med dermatomyosit (empacific)
En fas 2, randomiserad, dubbelblind, placebokontrollerad, multicenterstudie för att utvärdera säkerheten, tolerabiliteten och effektiviteten av flera dosregimer av Empasiprubart hos vuxna med dermatomyosit
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).
