To Assess the Relative Bioavailability (BA) of TRIUMEQ® and Dolutegravir and Lamivudine (DTG/3TC) Pediatric Dispersible Tablet Formulations in Healthy Volunteers

A 2-Part, Phase I, Single-Dose, 3-Period Crossover Relative Bioavailability Study of a Pediatric TRIUMEQ Dispersible Tablet and Pediatric Dolutegravir and Lamivudine (DTG/3TC) Fixed Dose Combination Dispersible Tablet Formulations as Compared With Adult Tablets in Healthy Volunteers

This is a 2-part, single-dose, open label, randomized 3-way cross-over study to compare BA of pediatric study drugs TRIUMEQ and (DTG/3TC) in healthy volunteers under fasted conditions. Study will be conducted in 2-parts. Each part 1 and part 2 will comprise of 3-treatment periods (TP) where Part 1, will assess BA, of pediatric TRIUMEQ dispersible tablets with an adult TRIUMEQ conventional tablet formulation and Part 2, will assess BA, of pediatric DTG/3TC dispersible tablets with adult DTG and 3TC conventional tablets formulation. Total duration of study is 9-weeks and will be conducted in approximately 36 subjects. The 2-parts, may be run in parallel as they are independent of each other.

The number of participants with abnormal clinically significant ECG findings are presented.	Baseline (Day -1)
Number of Participants With Abnormal ECG Findings in Part 2	Full 12-lead ECGs were recorded with the participant in a supine position. Absolute QTc Interval: >450, absolute PR Interval: <110 and Absolute QRS Interval: <75 were considered to be potential clinically significant ECG finding. The number of participants with abnormal clinically significant ECG findings are presented	Baseline (Day -1)
Absolute Values for Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) of Part 1	Blood pressure of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention and Day 2 of each treatment period
Absolute Values for Pulse Rate in Part 1	Pulse rate of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention and Day 2 of each treatment period
Absolute Values for Temperature in Part 1	Temperature of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention dose and Day 2 of each treatment period
Absolute Values for SBP and DBP of Part 2	Blood pressure of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention dose and Day 2 of each treatment period
Absolute Values for Pulse Rate in Part 2	Pulse rate of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention dose and Day 2 of each treatment period
Absolute Values for Temperature in Part 2	Temperature of participants were measured at indicated time points in semi-supine position after 5 minutes rest.	Day 1 at 4 hours post intervention dose and Day 2 of each treatment period
Change From Baseline in SBP and DBP of Part 1	Blood pressure of participants were measured at indicated time points in semi-supine position after 5 minutes rest. Day 1 (Pre-dose) value was defined as Baseline for vital sign parameters. Change from Baseline value is calculated as the value at the post-dose visit minus the Baseline value.	Baseline (Day 1, pre-dose), Day 1- 4 hours and Day 2
Change From Baseline in Pulse Rate of Part 1	Pulse rate of participants were measured at indicated time points in semi-supine position after 5 minutes rest. Day 1 (Pre-dose) value was defined as Baseline for vital sign parameters. Change from Baseline value is calculated as the value at the post-dose visit minus the Baseline value.	Baseline (Day 1, pre-dose), Day 1- 4 hours and Day 2
Change From Baseline in Temperature of Part 1	Temperature of participants were measured at indicated time points in semi-supine position after 5 minutes rest. Day 1 (Pre-dose) value was defined as Baseline for vital sign parameters. Change from Baseline value is calculated as the value at the post-dose visit minus the Baseline value.	Baseline (Day 1, pre-dose), Day 1- 4 hours and Day 2
Change From Baseline in SBP and DBP of Part 2	Blood pressure of participants were measured at indicated time points in semi-supine position after 5 minutes rest. Day 1 (Pre-dose) value was defined as Baseline for vital sign parameters. Change from Baseline value is calculated as the value at the post-dose visit minus the Baseline value.	Baseline (Day 1, pre-dose), Day 1- 4 hours and Day 2
