Switch Study to Evaluate the Safety and Efficacy of Emtricitabine/Rilpivirine/Tenofovir Alafenamide (FTC/RPV/TAF) Fixed Dose Combination (FDC) in HIV-1 Positive Adults Who Are Virologically Suppressed on Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate (FTC/RPV/TDF)

Phase 3
Completed
Conditions
HIV-1 Infection

Gilead Sciences
Brief Summary

The primary objective of this study is to evaluate the noninferiority of switching to emtricitabine/rilpivirine /tenofovir alafenamide (FTC/RPV/TAF) fixed-dose combination (FDC) as compared to continuing FTC/RPV/tenofovir disoproxil fumarate (TDF) FDC (FTC/RPV/TDF) 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 FTC/RPV/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. After reaching HIV-1 RNA < 50 copies/mL, single values of HIV-1 RNA ≥ 50 copies/mL followed by resuppression, are allowed
  • 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 (≤ 26 μmol/L), or normal direct bilirubin
  • Adequate hematologic function (absolute neutrophil count ≥ 1,000/mm^3 (1.00 GI/L); platelets ≥ 50,000/mm^3 (50 GI/L); hemoglobin ≥ 8.5 g/dL (85 g/L))
  • 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 (1.17 mL/sec) 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 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

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 US FDA-defined 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.

The percentage of participants with HIV-1 RNA ≥ 50 copies/mL at Week 96 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.
