This randomized, double-blind, placebo-controlled, parallel-group study will evaluate the safety and pharmacokinetics of subcutaneous lebrikizumab in healthy Japanese volunteers. Healthy Japanese and Caucasian volunteers will be randomized to receive a single subcutaneous dose of either lebrikizumab or placebo.

Official Title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Study of the Safety, Tolerability, and Pharmacokinetics of Subcutaneous Doses of Lebrikizumab in Healthy Japanese and Caucasian Volunteers

Further study details as provided by Genentech:

Primary Outcome Measures:
  • Safety: Incidence of adverse events in healthy Japanese subjects [ Time Frame: 120 days ] [ Designated as safety issue: No ]
  • Pharmacokinetics in healthy Japanese subjects: Area under the concentration-time curve (AUC) [ Time Frame: 120 days ] [ Designated as safety issue: No ]
