Bioavailability Study of 10 Milligram (mg) and 5 mg Tablets Versus Conventional Tablets of Dolutegravir

A 2-Part, Phase I, Single Dose, Crossover Relative Bioavailability Study of Both TIVICAY 10 mg Conventional Tablets and 5 mg Dispersible Tablets Compared to Conventional TIVICAY Tablets in Fasted Healthy Adult Subjects

The aim of this cross-over study is to compare the relative bioavailability and pharmacokinetic parameters of both 10 mg conventional tablets and 5 mg dispersible tablets of dolutegravir (DTG) with that of 25 mg or 50 mg conventional DTG tablets. The study will be carried out in 2 parts. Part 1 of the study will be open-label, 2 period designs with a wash out period of at least 7 days between the dosing periods. Subjects will be randomized to receive either single dose of five 10 mg DTG tablets or one 50 mg DTG tablet in a crossover manner in the fasting state. Part 2 of the study will be a 3 period crossover design with a wash out period of at least 7 days between the dosing periods. Subjects will be randomized to receive either single dose of five 5 mg DTG tablets (administered as dispersed with water or directly to mouth) or one 25 mg DTG tablet in a crossover manner in the fasting state. Subjects will have a follow-up visit 7-10 days post last dose of study treatment. Approximately 14 healthy subjects will participate in Part 1 and approximately 24 healthy subjects will participate in Part 2 of the study. The total duration of Part 1 will be approximately 7 to 8 weeks and that of part 2 will be approximately 8 to 9 weeks.

Up to 25 days in Part 1
Urine Potential of Hydrogen (pH) Analysis by Dipstick Method for Part 1	Urinary pH measurement is a routine part of urinalysis. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). Urine samples were collected for the measurement of urine pH by dipstick method up-to follow-up (Day 25) in Part 1. Only categories with significant values have been presented. Only those participants with data available at the specified time were analyzed (represented by n=x,x in the category titles).	Up to 25 days in Part 1
Urine Specific Gravity Analysis by Dipstick Method for Part 1	Urinary specific gravity measurement is a routine part of urinalysis. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. The concentration of the excreted molecules determines the urine's specific gravity. Urine samples were collected for the measurement of urine specific gravity by dipstick method up-to follow-up (Day 25) in Part 1. Only categories with significant values have been presented. Only those participants with data available at the specified time were analyzed (represented by n=x,x in the category titles).	Up to 25 days in Part 1
