A Randomised Double-blind (Sponsor Open), Placebo Controlled, Single Ascending Dose, First Time in Human Study in Participants With Mild to Moderate Asthma to Assess Safety, Tolerability, Immunogenicity, Pharmacokinetics and Pharmacodynamics of GSK3511294 Administered Subcutaneously
In Brief
A Phase 1 clinical trial evaluating GSK3511294, Placebo, and 1 other intervention for Asthma. Completed, enrolled 50 participants across 5 sites in 2 countries.
Detailed 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.

Timeline
Interventions
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.
Matching Placebo will consist of 0.9% w/v sodium chloride which will be administered by the SC route.
Salbutamol/albuterol will be supplied to all subjects for use as rescue medication during the study.
