Brief Summary

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.

  7. Herbal supplements (including St. John's Wort) and hormone replacement therapy must be discontinued 14 days prior to the first dose of study medication.
  8. Vaccination with live virus, attenuated live virus, or any live viral components within the 6 weeks prior to the first dose of study drug or is to receive these vaccines at any time during treatment or within 8 weeks following completion of study treatment.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
