Researchers are evaluating the safety, pharmacokinetics, and pharmacodynamics of TRB-061, a drug given by subcutaneous injection, in healthy adults and patients with moderate-to-severe atopic dermatitis (AD). This Phase 1a/1b randomized, double-blind, placebo-controlled study includes multiple parts to assess single and multiple doses. The study may adjust the number of dosing groups in the first two parts based on ongoing results. In Part 1, healthy adults receive a single dose of TRB-061 or placebo, followed by 12 weeks of monitoring. In Part 2, healthy adults receive three doses every four weeks over eight weeks, with a 10-week follow-up. Part 3 involves participants with moderate-to-severe AD receiving four doses of TRB-061 or placebo over 12 weeks, followed by a follow-up period. After the main study, those on placebo may have the option to receive the active treatment. Participants will undergo regular safety assessments including medical history, physical exams, laboratory tests, and monitoring for adverse events from screening through follow-up. Researchers will measure the incidence of adverse events and serious adverse events across all parts of the study. The total participation duration varies by part but includes follow-up lasting up to 12 weeks after dosing to ensure safety and collect pharmacological data.
