Phase 1
Completed
Conditions
Moderate-to-severe Atopic Dermatitis
Interventions
Drug: Placebo
Registration Number
NCT04893941
Lead Sponsor
Keymed Biosciences Co.Ltd
Brief Summary

This is a multi-center, randomized, double blind, placebo-controlled multiple dose escalation study to evaluate the safety, tolerance, PK, PD, immunogenicity and preliminary efficacy of subcutaneously CM310 in moderate-severe AD subjects.

Detailed Description

The study consists of 3 periods, a up-to-4-week Screening Period, a 4-week randomized Treatment Period and a 8-week Safety Follow-up Period.
