A Study to Evaluate the Pharmacokinetics of Rilpivirine/Tenofovir/Emtricitabine After a Single-Oral Administration in Healthy Japanese Adult Male Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the pharmacokinetics (PK) of rilpivirine/Tenofovir/Emtricitabine (RPV/TFV/FTC) after a single-oral administration of Complera (the fixed-dose combination of RPV, FTC, Tenefovir disoproxil fumarate [TDF]) to healthy Japanese adult male participants.

Detailed Description
-----------------
This is a single center, open-label, single oral dose study in healthy Japanese adult male participants. The study consists of 3 phases; a screening phase up to 27 days (Day -28 to Day -2), an in-patient phase from Day -1 to Day 3 (dosing day is Day 1), and a follow-up assessment phase from Day 4 to the last follow-up assessment scheduled on Day 15 or at the time of early withdrawal. All participants will receive a single oral dose of one Complera tablet on Day 1 within 5 minutes after completion of the standardized breakfast. Pharmacokinetics of RPV/TFV/FTC will be assessed as the primary objective of the study. Safety of each participant will be assessed throughout the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Plasma Concentration (Cmax) | The Cmax is the maximum observed plasma concentration of rilpivirine, tenofovir, emtricitabine. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Time to Reach Maximum Observed Plasma Concentration (Tmax) | The Tmax is defined as actual sampling time to reach maximum observed analyte (rilpivirine/tenofovir/emtricitabine) concentration. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last]) | The AUC (0-last) is the area under the plasma concentration-time curve for rilpivirine/tenofovir/emtricitabine from time zero to last quantifiable time. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Elimination Rate Constant (Lambda[z]) | Lambda(z) is first-order elimination rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Elimination Half-Life (t1/2) | The elimination half-life (t1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration. It is associated with the terminal slope of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z). | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Apparent Volume of Distribution (Vdz/F) | Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vdz/F) is influenced by the fraction absorbed. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose | 
| Apparent Clearance (CL/F) | Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. | Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 16, 24, 36, 48, 72, 96, 120, 168 and 192 hours post-dose |
