Study Testing Response Effect of KY1005 Against Moderate-to-Severe Atopic Dermatitis, The STREAM-AD Study

This is an interventional, randomized, parallel group, treatment, Phase IIb, double blind, 5-arm study to assess the effect of Anti-OX40L Monoclonal Antibody (KY1005) in adult participants with moderate to severe atopic dermatitis. The estimated duration is 28 days for screening and then up to approximately day 477 (last dose no later than day 337+140 days safety follow-up) for all patients unless enrolled into the LTE (Long-Term Extension) protocol (NCT05492578) at either Day 169 depending on responder status or no later than Day 365 due to loss of clinical response.
