Purpose

The primary objective of this study is to evaluate the effect of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) tablet on renal parameters at Week 24 in treatment-naive and treatment-experienced HIV-positive, adults with mild to moderate renal impairment.

Official Title

A Phase 3 Open-label Safety Study of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide Single-Tablet Regimen in HIV-1 Positive Patients With Mild to Moderate Renal Impairment

Eligibility Criteria

Ages Eligible for Study: Older than 18 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. Cohort 1 (treatment-experienced switch) - Must not have a history of known resistance to elvitegravir (EVG), tenofovir disoproxil fumarate (TDF), or emtricitabine (FTC) - Plasma HIV-1 RNA concentrations (at least two measurements) at undetectable levels (according to the local assay being used) in the 6 months preceding the screening visit and have HIV-1 RNA < 50 copies/mL at screening - Estimated glomerular filtration rate (GFR) 30-69 mL/min according to the Cockcroft-Gault formula for creatinine clearance, using actual weight - May be currently enrolled in Gilead studies GS-US-236-0102, GS-US-236-0103, and GS-US-216-0114, but will be eligible to enroll only after the Week 144 visit for that study is complete; or currently receiving Stribild® (STB) or atazanavir (ATV)/cobicistat (COBI) + Truvada (TVD) in Gilead studies GS-US-236-0104 or GS-US-216-0105, but will be eligible to enroll only after the Week 48 visit for that study is complete. Cohort 2 (treatment-naive) - Plasma HIV-1 RNA levels ≥ 1,000 copies/mL at screening - Screening genotype report provided by Gilead Sciences must show sensitivity to EVG, FTC, and TDF - No prior use of any approved or investigational antiretroviral drug for any length of time, except the use for pre-exposure prophylaxis (PrEP), or post-exposure prophylaxis (PEP), up to 6 months prior to screening - Estimated GFR 30-69 mL/min according to the Cockcroft Gault formula for creatinine clearance, using actual weight All Cohorts: All individuals must meet all of the following inclusion criteria to be eligible for participation in this study: - The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures - CD4+ count of ≥ 50 cells/μL - Stable renal function: serum creatinine measurements to be taken at least once (within three months of screening) - Cause of underlying chronic kidney disease (eg hypertension, diabetes) stable, without change in medical management, for 3 months prior to baseline - Normal electrocardiogram (ECG) - Hepatic transaminases (AST and ALT) ≤ 5 x upper limit of normal (ULN) - Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin - Adequate hematologic function - Serum amylase ≤ 5 x ULN - Females of childbearing potential must agree to utilize highly effective contraception methods (two separate forms of contraception, one of which must be an effective barrier method, or be non-heterosexually active, practice sexual abstinence) from screening throughout the duration of study treatment and for 30 days following the last dose of study drug - Females who utilize hormonal contraceptive as one of their birth control methods must have used the same method for at least three months prior to study dosing - Males must agree to utilize a highly effective method of contraception during heterosexual intercourse throughout the study period and for 30 days following discontinuation of investigational medicinal product. A highly effective method of contraception is defined as two separate forms of contraception, one of which must be an effective barrier method, or males must be non-heterosexually active, or practice sexual abstinence Key
Exclusion Criteria:
  1. - A new AIDS-defining condition (excluding CD4 cell count and percentage criteria) diagnosed within the 30 days prior to screening,with the exception of the first two bullet points - Hepatitis C virus (HCV) antibody positive. Individuals who are HCV positive, but have a documented negative HCV RNA, are eligible - Hepatitis B surface antigen (HBVsAg) positive - Individuals receiving drug treatment for Hepatitis C, or individuals who are anticipated to receive treatment for Hepatitis C during the course of the study - Individuals experiencing decompensated cirrhosis (eg, ascites, encephalopathy, etc.) - Females who are breastfeeding - Positive serum pregnancy test - Have an implanted defibrillator or pacemaker - Current alcohol or substance use judged by the Investigator to potentially interfere with study compliance - A history of malignancy within the past 5 years or ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous carcinoma - Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to baseline - Individuals on hemodialysis, other forms of renal replacement therapy, or on treatment for underlying kidney diseases (including prednisolone and dexamethasone) - Individuals receiving ongoing therapy with any medications not to be used with EVG, COBI, FTC, or TAF or individuals with any known allergies to the excipients of E/C/F/TAF Note: Other protocol defined Inclusion/Exclusion criteria may apply.
