Safety, Tolerability, Pharmacokinetics, Pharmacodynamics of GSK2330811 in Healthy Japanese Participants

This is a randomized, double-blind (sponsor-open), placebo-controlled, single-center study involving Japanese participants. The purpose of the study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity after a single subcutaneous (SC) dose of GSK2330811 in healthy Japanese participants. GSK2330811 is a humanized immunoglobulin G1 (IgG1) monoclonal antibody that binds and inhibits the action of Oncostatin M (OSM) and is being developed for the treatment of Crohn\'s disease (CD) and Systemic sclerosis (SSc). Participants will be randomized to receive either GSK2330811 (450 milligram \[mg\]) or placebo in an approximate ratio of 7:3.
