简要总结
This study is the first-in-human (FIH) study of BGB-45035. The study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of BGB-45035 with both a single dose and multiple doses administered at different dose levels in healthy participants, followed by a Part E to evaluate the safety and tolerability of BGB-45035 in adults with autoimmune dermatological diseases like atopic dermatitis (AD) and prurigo nodularis (PN). An additional biomarker cohort will be evaluated in Part F.
Study details include:
- The study duration will be up to 24 months.
- The treatment duration will be up to 14 days for Parts A-D, up to 12 weeks for Part E, and up to 3 weeks for Part F.
- Safety follow-up 30 days after last dose of study drug.
