Brief Summary

The purpose of the study is to evaluate the bioequivalence between Fixed-dose Combination (FDC) tablet formulation of Dolutegravir (DTG) 50 milligrams (mg) and Rilpivirine (RPV) 25 mg versus co-administration of the separate tablet formulations of DTG 50 mg plus RPV 25 mg, in the fed state. This pivotal bioequivalence study, is to serve as a pharmacokinetic (PK) bridge to the ongoing Phase 3 trials with the separate agents. This study will be conducted under fed conditions to appropriately mimic the conditions in the Phase 3 trials. This is a single-center, randomized, open-label, 2-period, single-dose, crossover study. A minimum of 86 healthy adult subjects will be randomized such that a minimum of approximately 82 evaluable subjects complete the study. The total duration of participation of a subject in this study will be approximately 8 weeks which includes a screening visit within 30 days prior to the first dose of study drug, two treatment periods each with a single dose of study drug and a follow-up visit within 12-17 days after the last dose of study drug. There will be a washout of at least 21 days between each dose of study drug.

A blinded (for treatment) review of DTG and RPV plasma concentration data for approximately the first 40 subjects will be conducted. If the within-subject coefficients of variation (CVw%) for either DTG or RPV maximal drug concentration (Cmax) values are >=31%; a sample size re-estimation will be employed and additional subjects (beyond the 86 planned) will be randomized for treatment in the study. Following the re-estimation, it is possible that up to approximately 154 healthy adult subjects (68 new subjects in addition to the planned 86 subjects above) will be randomized such that a maximum of approximately 146 evaluable subjects could complete the study.
