Summary
This early-stage study tests a new drug called BBT001 in healthy volunteers and adults with moderate-to-severe atopic dermatitis (eczema). The main goal is to check safety and how the drug moves through the body. About 198 participants will receive either BBT001 or a placebo, with doses increased gradually to find the right range.
