Study to Evaluate Switching From a Regimen Consisting of Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate (EFV/FTC/TDF) Fixed Dose Combination (FDC) to Emtricitabine/Rilpivirine/Tenofovir Alafenamide (FTC/RPV/TAF) FDC in Virologically-Suppressed, HIV-1 Infected Adults

Phase 3
Completed
Conditions
HIV-1 Infection
Interventions
Drug: EFV/FTC/TDF
Drug: EFV/FTC/TDF Placebo
Drug: FTC/RPV/TAF Placebo
Registration Number
NCT02345226
Lead Sponsor
Gilead Sciences
Brief Summary

The primary objective of this study is to evaluate the non-inferiority of switching to emtricitabine/rilpivirine/tenofovir alafenamide (FTC/RPV/TAF) fixed dose combination (FDC) as compared to continuing the non-nucleoside reverse transcriptase inhibitor (NNRTI) regimen of efavirenz /FTC/tenofovir disoproxil fumarate (EFV/FTC/TDF) FDC in virologically-suppressed HIV-1 infected participants.

Inclusion Criteria
  • The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
  • Currently receiving EFV/FTC/TDF FDC for ≥ 6 consecutive months preceding the screening visit
  • Documented plasma HIV-1 RNA levels < 50 copies/mL (or undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is > 50 copies/mL) for ≥ 6 months preceding the screening visit. Unconfirmed virologic elevation of ≥ 50 copies/mL after previously reaching viral suppression (transient detectable viremia, or "blip") and prior to screening is acceptable
  • Have no documented resistance to any of the study agents at any time in the past
  • HIV-1 RNA < 50 copies/mL at the screening visit
  • Hepatic transaminases (AST and ALT) ≤ 5 × upper limit of normal (ULN)
  • Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin
  • Adequate hematologic function (absolute neutrophil count ≥ 1,000/mm^3; platelets ≥ 50,000/mm^3; hemoglobin ≥ 8.5 g/dL)
  • Serum amylase ≤ 5 × ULN (individuals with serum amylase > 5 × ULN will remain eligible if serum lipase is ≤ 5 × ULN)
  • Normal ECG (or if abnormal, determined by the Investigator to be not clinically significant)
  • Adequate renal function: Estimated glomerular filtration rate ≥ 50 mL/min according to the Cockcroft-Gault formula

Key

Exclusion Criteria
  • Hepatitis B surface antigen (HBsAg) positive
  • Hepatitis C antibody positive with detectable hepatitis C virus (HCV) RNA (individuals who have HCV antibody but no detectable HCV RNA are eligible to enroll)
  • Individuals experiencing or with a medical history of decompensated cirrhosis (e.g., ascites, encephalopathy, etc.)
  • Females who are breastfeeding
  • Positive serum pregnancy test
  • Current alcohol or substance use judged by the Investigator to potentially interfere with the individual's study compliance
  • A history of malignancy within the past 5 years (prior to screening) or ongoing malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or resected, non-invasive cutaneous squamous carcinoma. Individuals with cutaneous KS are eligible, but must not have received any systemic therapy for KS within 30 days of Baseline/Day 1 and must not be anticipated to require systemic therapy during the study
  • Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Baseline/Day 1
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the individual unsuitable for the study or unable to comply with dosing requirements
  • Participation in any other clinical trial (including observational trials) without prior approval from the sponsor is prohibited while participating in this trial
  • Individuals receiving ongoing therapy with any of the disallowed medications listed in the protocol, including drugs not to be used with FTC, RPV and/or TAF; or individuals with any known allergies to the excipients of FTC/RPV/TAF

Note: Other protocol defined inclusion/exclusion criteria may apply.

Open Label Extension PhaseFTC/RPV/TAFAfter the Week 96 visit, participants will be given the option to receive open label FTC/RPV/TAF for up to an additional 48 weeks. In countries where FTC/RPV/TAF is not yet commercially available, participants will be given the option to receive open-label FTC/RPV/TAF and attend visits every 12 weeks until FTC/RPV/TAF becomes commercially available, or until Gilead elects to discontinue the study, whichever occurs first.
Primary Outcome Measures

Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 as Defined by the US FDA-defined Snapshot AlgorithmWeek 48

The percentage of participants achieving HIV-1 RNA \< 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.

Percent Change From Baseline in Hip Bone Mineral Density (BMD) at Week 48Baseline; Week 48

Hip BMD was assessed by dual energy x-ray absorptiometry (DXA) scan.

Change From Baseline in HIVSI Score at Week 96Baseline; Week 96

The HIV Symptoms Index was a 20-item, self-reported measure that addressed presence and perceived distress linked to symptoms commonly associated with HIV or its treatment. Twenty HIV symptoms including Fatigue, Fever, Dizziness, Hand/Foot Pain, Memory Loss, Nausea, Diarrhea, Sadness, Nervous/anxious, Sleep Trouble, Skin Problems, Cough, Headache, Appetite Loss, Stomach Pain, Muscle/Joint Pain, Sex Problems, Change in Fat Deposits, Weight Loss, and Hair Loss were assessed. There were 5 possible responses (0 = I don't have this symptom; 1 = It doesn't bother me; 2 = It bothers me a little; 3 = It bothers me; and 4 = It bothers me a lot) for each HIV symptom. Total HIV Symptoms Index Score was derived from all 20 HIV symptoms by counting the number of bothersome symptoms. Total score would be missing if any of the individual items were missing.
