A Phase I/IIA, Randomized, Placebo-Controlled, Single-Ascending Dose (Part A, Participant- and Investigator-Blind) and Repeated-Dose (Part B, Participant-, Investigator-, and Sponsor-Blind) Study to Investigate the Safety, Pharmacokinetics and Efficacy of UCB9741 in Healthy Study Participants (Part A) and in Study Participants With Moderate-to-Severe Atopic Dermatitis (Part B)

Brief summary

The purpose of the study is to investigate the safety and tolerability of single-ascending doses of UCB9741 administered by intravenous infusion or subcutaneous injection to healthy study participants and following repeat dosing at a single dose level in study participants with atopic dermatitis. Furthermore, the clinical outcome in study participants with atopic dermatitis after administration of UCB9741 by intravenous infusion will be investigated.
