The goal of this clinical trial is to evaluate the safety and tolerability of QX-453, an investigational treatment, in healthy Chinese volunteers and patients with moderate-to-severe atopic dermatitis. The study will assess how the drug is absorbed and processed by the body, and check for any side effects. Participants will receive single or repeated oral doses of QX-453 under close medical supervision, with regular safety and clinical assessments throughout the trial.
