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. A SAE is defined as any untoward medical occurrence that, at any dose: 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, and other situations which involve medical or scientific judgment.

Area Under the Plasma Concentration Time Curve From 0 to t (AUC[0-t]) of GSK3772847
Day 1: Pre-dose, 2, 4, 8 hours post-dose; Days 2, 3, 4, 5, 6, 9, 15, 29, 43, 57, 71 and 85

Blood samples were collected at indicated time points for pharmacokinetic analysis of GSK3772847. Pharmacokinetic Population consisted of all randomized participants who received at least one dose of study treatment, and for whom at least one pharmacokinetic sample was obtained, analyzed and measurable.
