- Brief Summary
The purpose of this study is to evaluate the pharmacokinetics and relative bioavailability of Emtricitabine (FTC) and Tenofovir alafenamide (TAF) when administered as a fixed-dose combination (FDC) with darunavir (DRV) and cobicistat (COBI) (darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) relative to administration as an FDC with Elvitegravir (EVG) and COBI (Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide), under fed conditions in healthy subjects (Panel 1); evaluate the single-dose pharmacokinetics and relative bioavailability of DRV, COBI, FTC and TAF when administered as an FDC (D/C/F/TAF) or as separate agents (D+C+FTC/TAF), under fed conditions in healthy subjects (Panel 2) and to evaluate the impact of food (fasting or high-fat breakfast) on the single-dose pharmacokinetics of DRV, COBI, FTC, and TAF when administered as an FDC (D/C/F/TAF) in healthy subjects (Panel 3).
- Detailed Description
This is a Phase 1, 3-panel, open-label, randomized, 2-way crossover study in healthy subjects. Healthy subjects will be divided over 3 panels (Panel 1, 2 and 3). Subjects will be randomized within each panel. In each panel, during 2 subsequent sessions, each subject will receive 2 treatments (Treatments A and B in Panel 1, Treatments C and D in Panel 2, and Treatments E and F in Panel 3). Each treatment is defined as follows: Treatment A: single oral dose of D/C/F/TAF 800/150/200/10 milligram (mg) as FDC tablet under fed conditions (standardized regular breakfast); Treatment B: single oral dose of E/C/F/TAF 150/150/200/10 mg as FDC tablet under fed conditions; Treatment C: single oral dose of D/C/F/TAF 800/150/200/10 mg as FDC tablet under fed conditions; Treatment D: single oral dose of DRV as 800-mg tablet, FTC/TAF as 200/10 mg tablet and COBI 150 mg tablet under fed conditions. Treatment E: single oral dose of D/C/F/TAF 800/150/200/10 mg as FDC tablet, under fasted condition and Treatment F: single oral dose of D/C/F/TAF 800/150/200/10 mg tablet, with a standardized high-fat breakfast. Each treatment will be separated by a washout period of at least 7 days. Primarily pharmacokinetic parameters will be assessed. Subjects' safety will be assessed throughout.
