Summary

GSK3511294 is a humanized monoclonal antibody antagonist of Interleukin (IL)-5 which is known to block binding of IL-5 to the IL-5 receptor complex, causing a reduction in the circulating population of eosinophils. This is a single ascending dose FTIH study to investigate safety, tolerability, immunogenicity, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK3511294, administered SC in subjects with mild to moderate asthma maintained on a low-medium daily dose of inhaled corticosteroids (ICS) or ICS/long acting beta-agonist (LABA), and short acting beta-agonist (SABA). The subjects will attend a pre-screen visit of up to 12 weeks before dosing for assessment of blood eosinophils. Eligible subjects with blood eosinophils \>=200 cells per microliter (cells/µL) will undergo a screening period of up to 4 weeks. The subjects will then be randomized into 5 cohorts. In each cohort, the subjects will be randomized to receive a single dose of GSK3511294 or placebo in a ratio of 3:1. The follow-up period will be up to 40 weeks post dose and will be dose-dependent. The scheduled maximum duration for each subject will be up to 44 weeks including up to 28 days of screening.

Conditions

Interventions

DRUG

GSK3511294

GSK3511294 will be available as a clear or opalescent, colorless or yellow to brown solution for injection at unit dose strength of 150 milligrams per milliliter (mg/mL). GSK3511294 will be diluted in 0.9% weight by volume (w/v) sodium chloride to achieve the desired concentration for administration. GSK3511294 will be administered by SC injection.

DRUG

Placebo

Matching Placebo will consist of 0.9% w/v sodium chloride which will be administered by the SC route.

DRUG

Salbutamol/albuterol

Salbutamol/albuterol will be supplied to all subjects for use as rescue medication during the study.
