Atopic Dermatitis, Healthy
Conditions
Brief summary
The main purpose of this study is to evaluate the safety and tolerability of LY3872386 in healthy participants and participants with atopic dermatitis. The safety of prednisone is also evaluated in healthy participants. Blood tests will be performed to investigate how the body processes the LY3872386 following single and multiple dosing in healthy participants and participants with atopic dermatitis. Blood tests will also be performed to investigate how the body processes the prednisone in healthy participants. The study is conducted in three parts (part A, B and C). The study will last up to approximately 85, 183 and 44 days for parts A, B, and C, respectively.

Pre-assignment details
The study was designed to include three parts (A, B, and C). Results are reported only for Part A, as Parts B and C were not initiated and the study was terminated early due to emerging nonclinical data. In Part A, single-ascending dose (SAD), of the LY3872386 (SAD Cohorts 1 and 2 and the sentinel pair in SAD Cohort 3,) was administered to healthy participants on Day 1, followed by a 12-week follow-up period.
