Description

Summary

This study is to evaluate the non-inferiority of switching to a tenofovir alafenamide (TAF)-containing fixed dose combination (FDC) relative to maintaining tenofovir disoproxil fumarate (TDF)-containing combination regimens in virologically suppressed HIV-infected participants as determined by having HIV-1 RNA < 50 copies/mL at Week 48.

Official Title

A Phase 3, Open-Label Study to Evaluate Switching From a TDF-Containing Combination Regimen to a TAF-Containing Combination Single Tablet Regimen (STR) in Virologically-Suppressed, HIV-1 Positive Subjects

Keywords

  • Completion of the Week 144 visit in studies GS-US-236-0102, GS-US-236-0103,GS-US-216-0114, or completion of the Week 96 visit in study GS-US-264-0110 (only participants on an EFV-based regimen), or completion of studies GS-US-236-0104,GS-US-216-0105
  • Plasma HIV-1 RNA concentrations at undetectable levels for at least 6 consecutive months prior to the screening visit and have HIV RNA < 50 copies/mL at the screening visit
  • Normal echocardiograph (ECG)
  • Estimated glomerular filtration rate (GFR) ≥ 50 mL/min according to the Cockcroft-Gault formula for creatinine clearance
  • Hepatic transaminases (AST and ALT) ≤ 5 × upper limit of the normal range (ULN)
  • Direct bilirubin ≤ 1.5 x ULN
  • Adequate hematologic function
  • Serum amylase ≤ 5 × ULN
  • Females of childbearing potential must agree to utilize highly effective contraception methods or be non-heterosexually active or practice sexual abstinence from screening throughout the duration of study treatment and for 12 weeks following the last dose of study drug if receiving EFV/FTC/TDF regimen, and 30 days for those assigned to all other regimens.
  • Female participants 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
  • Female participants who have stopped menstruating for ≥ 12 months but do not have documentation of ovarian hormonal failure must have a serum follicle stimulating hormone (FSH) level at screening within the post-menopausal range based on the Central Laboratory reference range

Key Exclusion Criteria:

  • A new AIDS-defining condition diagnosed within the 30 days prior to screening
  • Hepatitis B surface antigen position
  • Hepatitis C antibody positive
  • Participants experiencing decompensated cirrhosis
  • 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 subject study compliance
  • 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
  • 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 dosing requirements
  • Participation in any other clinical trial without prior approval from the sponsor is prohibited while participating in this trial
  • Participants receiving ongoing therapy with drugs not to be used with elvitegravir(EVG), COBI, FTC, TDF, ATV, RTV, EFV, and TAF or participants with any known allergies to the excipients of E/C/F/TDF, E/C/F/TAF, EFV/FTC/TDF, ATV, COBI, RTV, or FTC/TDF
