Study Endpoints
Primary Endpoints
Area Under the Concentration-time Curve From Time Zero (Pre-dose) Extrapolated to Infinite Time (AUC[0-infinity]) of GSK3640254 Following Single Oral Dose in Healthy Participants
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. Pharmacokinetic (PK) parameters of GSK3640254 were calculated using non-compartmental methods. Geometric mean and percentage (%) geometric coefficient of variation have been presented.

Area Under the Concentration-time Curve From Zero to Time of Last Sample Taken (AUC[0-t]) of GSK3640254 Following Single Oral Dose in Healthy Participants
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, and 72 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of GSK3640254 were calculated using non-compartmental methods. Geometric mean and % geometric coefficient of variation have been presented. Statistical analysis of PK parameters was done using mixed effect model for evaluation of relative bioavailability (Frel). Point estimate and 90% confidence interval (CI) for the ratio of geometric least square mean of the test mesylate salt capsule to the reference Hydrochloride capsule were calculated for AUC(0-t).

Maximum Observed Concentration (Cmax) of GSK3640254 Following Single Oral Dose in Healthy Participants
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, and 72 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of GSK3640254 were calculated using non-compartmental methods. Geometric mean and % geometric coefficient of variation have been presented. Statistical analysis of PK parameters was done using mixed effect model for evaluation of Frel. Point estimate and 90% CI for the ratio of geometric least square mean of the test mesylate salt capsule to the reference Hydrochloride capsule were calculated for Cmax.

Time to Reach Maximum Observed Concentration (Tmax) of GSK3640254 Following Single Oral Dose in Healthy Participants
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, and 72 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of GSK3640254 were calculated using non-compartmental methods. Median and full range of Tmax have been presented.

Concentration at 24 Hours Post-dose (C24h) of GSK3640254 Following Single Oral Dose in Healthy Participants
Pre-dose, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12 and 24 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of GSK3640254 were calculated using non-compartmental methods. Geometric mean and % geometric coefficient of variation have been presented.
