Safety, Tolerability, and Pharmacokinetics Study of ZL-1503 in Healthy Adults and Adults With Moderate to Severe Atopic Dermatitis

What this Trial Is About

Researchers are studying ZL-1503 in a phase 11b clinical trial to assess its safety, tolerability, and how the body processes the drug. The study includes both healthy adults and adults with moderate to severe atopic dermatitis AD, a skin condition characterized by inflammation and itching. This randomized, double-blind, placebo-controlled trial aims to better understand the effects of ZL-1503 in these groups. The trial has two parts Part A involves single increasing doses of ZL-1503 given to healthy volunteers, while Part B involves multiple increasing doses given to adults with moderate to severe AD. Participants will receive either ZL-1503 or a placebo. The study monitors participants closely during dosing to evaluate how the drug is tolerated and how it behaves in the body. Participants will undergo various assessments throughout the study, including monitoring for adverse events, vital signs, laboratory tests, and electrocardiograms ECGs for up to 48 weeks after the last dose. These evaluations help researchers track safety and any potential side effects. The total participation period can last up to 48 weeks following dosing to ensure thorough observation.
