October 7, 2021 updated by: GlaxoSmithKline
A Randomized, Double-blind, Single Ascending Dose Study to Determine the Safety and Tolerability, Pharmacokinetics and Pharmacodynamics of GSK3772847 Administered Subcutaneously in Healthy Participants
GSK3772847, an anti-interleukin (IL) 33-receptor monoclonal antibody, is a novel treatment for asthma.
The purpose of this study to evaluate the safety and tolerability, PK and PD of single ascending doses of GSK3772847 administered subcutaneously (SC) to healthy participants.
This study will also establish the bioavailability of SC formulation and evaluate the safety in particular injection site tolerability of route.
Participants will either receive a single dose of 70 milligram (mg) GSK3772847 or placebo in (Cohort 1) and 140 mg GSK3772847 or placebo in Cohorts 2, 3 (Japanese participants) and 4 (Chinese participants).
The site of injection will be upper arm; abdomen or thigh for cohorts 1 and 2 with cohorts 3 and 4 will receive injections in the upper arm only.
Approximately, the total duration of study will be up to 89 days.

- Chinese Participants are eligible based on meeting all of the following: healthy male and female participants born in mainland China; are descendants of four Chinese grandparents and two Chinese parents; holding a Chinese passport or identity papers; being able to speak Chinese; have lived outside China for less than 10 years at the time of screening; Body weight 35-150 kilogram (kg) and body mass index (BMI) within the range 18-32 kilogram per square meter (kg/m2) (inclusive).
