Arm && Interventions

Group	Intervention	Description
GSK3862995B	GSK3862995B	Participants of Chinese, Japanese, or European ancestries will receive GSK3862995B.
Placebo	Placebo	Participants of Chinese, Japanese, or European ancestries will receive matching placebo.

Primary Outcome Measures

Name	Time	Method
Number of Participants with Adverse Events (AE)	Up to Week 44 (End of follow up visit)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention.
Number of Participants with Serious Adverse Events (SAE)	Up to Week 44 (End of follow up visit)	An SAE is defined as any untoward medical occurrence that, at any dose, meets one or more of the criteria: results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant, or abnormal pregnancy outcomes (such as, spontaneous abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy).
Number of Participants with Clinically Significant Changes in Clinical Laboratory Values	Up to Week 36	Number of Participants with clinically significant changes in clinical laboratory values (hematology, chemistry and urinalysis) will be assessed.
Number of Participants with Clinically Significant Changes in Vital Signs	Up to Week 36	Number of Participants with clinically significant changes in vital signs will be assessed.
Number of Participants with Clinically Significant Changes in 12-lead (Electrocardiogram (ECG)	Up to Week 36	Number of Participants with clinically significant changes in 12-lead ECG will be assessed.
Area Under the Serum Concentration-time Curve Extrapolated to Infinity (AUC[0-inf]) of GSK3862995B	Up to Week 36	Blood samples will be collected to determine the pharmacokinetic profile of GSK3862995B.
Maximum Observed Concentration (Cmax) of GSK3862995B	Up to Week 36	Blood samples will be collected to determine the pharmacokinetic profile of GSK3862995B.
