Study to Evaluate the Pharmacokinetic (PK) Interactions Between GSK3640254 and Dolutegravir (DTG)

This is an open-label, single-sequence, two-way drug interaction study to investigate the PK, safety and tolerability of GSK3640254 and DTG when administered alone or in combination in healthy subjects. Treatment of human immunodeficiency virus (HIV) infection frequently involves combination therapy. Data from this study will contribute to dosing recommendations when GSK3640254 and DTG are given in combination. The study will consist of a Screening period and 3 sequential treatment periods. Subjects will be administered DTG 50 milligrams (mg) once daily (QD) in Period 1 followed by GSK3640254 200 mg QD in Period 2. There will be a washout period of 4 days between Periods 1 and 2. In Period 3, subjects will be co-administered DTG 50 mg QD and GSK3640254 200 mg QD. The total duration of the study will be approximately 55 days, including Screening.

    Time frame: Days 2, 3, 4 and 5

    Body temperature was measured in the semi-recumbent position after at least 5 minutes of rest for the participant in a quiet setting without distractions.

  117. Period 2: Absolute Values for Body Temperature

    Time frame: Days 2, 3, 4, 5, 6 and 7

    Body temperature was measured in the semi-recumbent position after at least 5 minutes of rest for the participant in a quiet setting without distractions.

  118. Period 3: Absolute Values for Body Temperature

    Time frame: Days 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11

    Body temperature was measured in the semi-recumbent position after at least 5 minutes of rest for the participant in a quiet setting without distractions.

  119. Period 2: Time of Maximum Observed Concentration (Tmax) of GSK3640254 for GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of GSK3640254. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  120. Period 3: Tmax of GSK3640254 for Dolutegravir + GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of GSK3640254. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  121. Period 2: Apparent Terminal Phase Half-life (T1/2) of GSK3640254 for GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of GSK3640254. The pharmacokinetic parameters were calculated by standard non-compartmental analysis. Data could not be determined due to limited sampling points after final dosing (during elimination phase). An accurate determination of GSK3640254 half-life would require sampling up to 3 times half-life (3 * approximately 24 hours). However sampling in Period 2 was performed up to only 24 hours post-dose.

  122. Period 3: T1/2 of GSK3640254 for Dolutegravir + GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of GSK3640254. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  123. Period 1: Tmax of Dolutegravir for Dolutegravir Arm

    Time frame: Day 5: Pre-dose, 1, 1.5, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of dolutegravir. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  124. Period 3: Tmax of Dolutegravir for Dolutegravir + GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of dolutegravir. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  125. Period 1: T1/2 of Dolutegravir for Dolutegravir Arm

    Time frame: Day 5: Pre-dose, 1, 1.5, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of dolutegravir. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.

  126. Period 3: T1/2 of Dolutegravir for Dolutegravir + GSK3640254 Arm

    Time frame: Day 7: Pre-dose, 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12 and 24 hours post-dose

    Blood samples were collected at the indicated time points for pharmacokinetic analysis of dolutegravir. The pharmacokinetic parameters were calculated by standard non-compartmental analysis.
