Renal Effect of Stribild or Other Tenofovir DF-containing Regimens Compared to Ritonavir-boosted Atazanavir Plus Abacavir/Lamivudine in Antiretroviral Treatment-naive HIV-1 Infected Adults

December 1, 2017 updated by: Gilead Sciences

A Randomized, Open Label, Phase 4 Study Evaluating the Renal Effect of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir DF or Other Tenofovir DF-containing Regimens (Ritonavir-boosted Atazanavir Plus Emtricitabine/Tenofovir DF or Efavirenz/Emtricitabine/Tenofovir DF) Compared to Ritonavir-boosted Atazanavir Plus Abacavir/Lamivudine in Antiretroviral Treatment-naïve HIV-1 Infected Adults With eGFR ≥70 mL/Min

The primary objective of this study is to assess glomerular function before and during administration of stribild (STB; elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF)) or a regimen containing TDF without cobicistat (COBI) as ritonavir (RTV)-boosted atazanavir (ATV/r) plus truvada (TVD; FTC/TDF) or atripla (ATR; efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF)) compared to a regimen containing neither TDF nor COBI as ATV/r plus abacavir/lamivudine (ABC/3TC) via determination of actual glomerular filtration rate (aGFR) using iohexol (a probe GFR marker) plasma clearance and estimated (calculated) glomerular filtration rate (eGFR).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Actual Glomerular Filtration Rate (aGFR) Using Iohexol Plasma Clearance (CLiohexol) at Week 24
Time Frame: Week 24
Week 24
Estimated GFR (eGFR) Calculated by Cockcroft-Gault Formula at Week 24
Time Frame: Week 24
GFR is a measure of the rate at which blood is filtered by the kidney. Cockcroft-Gault is an equation (calculation) used to estimate GFR based on serum creatinine, weight, and gender. eGFR = (140 - age) * (mass in kg) * (0.85 if female) divided by 72 * serum creatinine in mg/dL
Week 24
Estimated GFR Calculated by Modification of Diet in Renal Disease (MDRD) Formula at Week 24
Time Frame: Week 24
MDRD is an equation (calculation) used to estimate GFR in participants with impaired renal function based on serum creatinine, age, race, and gender. eGFR (mL/min/1.73 m^2) = 186 * (Scr)^-1.154 * (Age)^(-0.203) * (0.742 if female) * (1.212 if black). Scr = serum creatinine in mg/dL
Week 24

Secondary Outcome Measures

Secondary Outcome Measures
