SKB575 (HBM7575) injection in healthy adults and adults with atopic dermatitis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double-blind, placebo-controlled Phase 1 study with two parts: a Phase Ia single ascending dose portion in healthy volunteers and a Phase Ib proof-of-concept portion in adults with moderate to severe atopic dermatitis. The study will monitor safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity after SKB575 or placebo injections. Participants will be randomly assigned and neither participants nor investigators will know treatment assignment. The trial is sponsored by Sichuan Kelun-Biotech and conducted at Huashan Hospital affiliated with Fudan University in Shanghai.
