Clinical Trial Summary

Research hypothesis:

Switching from dual regimens based on dolutegravir plus a RTI to a single tablet regimen of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF), lowers the exposure to Residual Viremia (and hence the risk of viral rebound), without increasing treatment toxicity.

Description:

Study design Randomized, single-center, open-label, 96-week superiority study. Patients with HIV-RNA <50 copies/mL while receiving DTG plus one RTI will be randomized 1:1 to continue the ongoing treatment or to switch to E/C/F/TAF.

Randomization list will be a computer-generated list (with equal block sizes) and will be incorporated within an electronic clinical report form (eCRF).

Patients will be evaluated at screening, baseline, week 4, 8, 16, 24, 32, 40, 48, 60, 72, 84, 96 or premature discontinuation.

At each visit the following evaluations will be performed:

1. clinical assessment.

2. routine laboratory tests (hematological tests and clinical chemistry). Additional blood samples will be collected at specified visits for storage and further determinations (e.g. RV by a single-copy assay).

During follow-up, at different timepoints, patients will additionally undergo HIV-DNA quantification in PBMCs (BL, 48 and 96 weeks) and quality of life (QOL) and adherence assessement (BL, 48 and 96 weeks).

Viral load will be assessed by Abbott Real time PCR (Abbott RealTime HIV-1) Residual viremia (RV) will be defined as any detectable HIV-RNA value below 50 copies/mL Virologic failure will be defined as a confirmed rebound in plasma HIV-RNA levels ≥ 50 copies/mL

Subjects who meet a protocol-defined virologic failure during follow-up will be discontinued from the study.

At virologic failure subjects will perform genotypic HIV resistance testing and a determination in plasma of elvitegravir or DTG Cthrough.

HIV-DNA will be extracted from 1x106 peripheral blood mononuclear cells (PBMCs) by using Qiagen DNA extraction kit and quantified by Real Time PCR (ABI Prism 7900).
