Brief 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.

A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0).
