Study to Evaluate the Safety and Efficacy of Stribild Versus Atripla in Human Immunodeficiency Virus, Type 1 (HIV-1) Infected, Antiretroviral Treatment-Naive Adults - Full Text View

Purpose

To evaluate the safety and efficacy of Stribild®, a single tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/cobicistat (COBI [GS-9350])/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF (Atripla®) in HIV-1 infected, antiretroviral treatment-naive adults. Stribild offers an alternative STR for patients who are not candidates for non-nucleoside reverse transcriptor-based STRs.

Primary Outcome Measures:

The Percentage of Participants With Virologic Success Using the Food and Drug Administration (FDA)-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 Ribonucleic Acid (RNA) < 50 Copies/mL at Week 48 [ Time Frame: Week 48 ]

Secondary Outcome Measures:

The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 96 [ Time Frame: Week 96 ]
The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 144 [ Time Frame: Week 144 ]
The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 192 [ Time Frame: Week 192 ]
The Percentage of Participants Achieving and Maintaining Confirmed HIV-1 RNA < 50 Copies/mL at Week 48 Using the FDA-defined Time to Loss of Virologic Response (TLOVR) Algorithm [ Time Frame: Week 48 ]
The Change From Baseline in Cluster Determinant 4 (CD4) Cell Count at Weeks 48, 96, 144, and 192 [ Time Frame: Baseline; Weeks 48, 96, 144, and 192 ]
Change = value of the relevant time point minus the baseline value
The Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 [ Time Frame: Week 48 ]

Criteria

Inclusion Criteria:

Ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
Plasma HIV-1 RNA levels ≥ 5,000 copies/mL
No prior use of any approved or investigational antiretroviral drug for any length of time
Screening genotype report must show sensitivity to FTC, TDF, and EFV

Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin
Adequate hematologic function
Serum amylase ≤ 5 x ULN
Males and females of childbearing potential must agree to utilize highly effective contraception methods from screening throughout the duration of study treatment and for 12 weeks following the last dose of study drug
Age ≥ 18 years
Life expectancy ≥ 1 year

Exclusion Criteria:

A new acquired immunodeficiency syndrome (AIDS)-defining condition diagnosed within the 30 days prior to screening
Receiving drug treatment for hepatitis C, or anticipated to receive treatment for hepatitis C
Subjects experiencing decompensated cirrhosis
Females who are breastfeeding
Positive serum pregnancy test (female of childbearing potential)
Implanted defibrillator or pacemaker
Current alcohol or substance use judged by the Investigator to potentially interfere with subject study compliance

Medications contraindicated for use with EVG, COBI, FTC, EFV, or TDF; or subjects with any known allergies to the excipients of Stribild or Atripla tablets
Participation in any other clinical trial without prior approval
Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the dosing requirements
