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

• Status: Completed
• Trial end date: 2014-09-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• 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

• Normal electrocardiogram (ECG)

• Adequate renal function (estimated glomerular filtration rate ≥ 70 mL/min according to the Cockcroft Gault formula)

• 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

• History of malignancy within the past 5 years or ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, noninvasive cutaneous squamous carcinoma

• Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to baseline

• 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
