Study to Evaluate the Safety, Tolerability and How IBI3013 is Taken up and Processed by the Body in Healthy Volunteers After Single-dose Administration, and in Non-segmental Vitiligo Patients and Alopecia Areata Patients After Multiple-dose Administration

Recruiting now · Phase 1 · Has a placebo group

Conditions studied: Healthy, Active Non-segmental Vitiligo, Severe Alopecia Areata

In brief

A multicenter clinical study to evaluate the safety, PK characteristics, immunogenicity characteristics, and PD characteristics of IBI3013 in healthy trial participants and active non-segmental vitiligo trial participants and severe alopecia areata trial participants. The study is divided into 2 parts, with Part 1 involving healthy trial participants lasting up to 24 weeks, and Part 2 involving active non-segmental vitiligo trial participants and severe alopecia areata trial participants lasting up to 48 weeks.
