Plasma viral load (HIV-1 RNA) 200 cells/µL at screening 5. Signed and dated written informed consent prior to inclusion. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 24 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range

Exclusion criteria

Exclusion criteria: 1. Plasma viral load (HIV-1 RNA) at screening >500,000 copies/mL 2. CD4+ T lymphocytes count at screening <200 cells/µL 3. Hepatitis B virus (HBV) 4. Severe hepatic impairment (Child-Pugh Class C) 5. Ongoing malignancy 6. Active opportunistic infection 7. Primary resistance to the study ARV drugs. 8. Ongoing therapy with any significant interaction with the study drugs. 9. Any verified Grade 4 laboratory abnormality 10. ALT or AST = 3xULN and/or bilirubin = 1.5xULN 11.

Design outcomes

Primary

MeasureTime frame
Main Objective: To compare HIV-1 RNA decay kinetics in semen in ART-naïve HIV-1 infected male individuals treated with DTG/3TC dual therapy versus BIC/FTC/TAF.;Secondary Objective: To compare HIV-1 RNA decay kinetics in rectal fluid in ART-naïve HIV-1 infected male individuals treated with DTG/3TC dual therapy versus BIC/FTC/TAF.; Primary end point(s): HIV-1 RNA decay in seminal plasma from baseline and up to 24 weeks after initiation of DTG/3TC vs Bictegravir/FTC/TAF. HIV-1 RNA decay in rectal fluid from baseline and up to 24 weeks after initiation of DTG/3TC vs Bictegravir/FTC/TAF. ;Timepoint(s) of evaluation of this end point: 24 weeks

Secondary

MeasureTime frame
Secondary end point(s): HIV-1 RNA decay in blood plasma from baseline and up to 24 weeks after initiation of DTG/3TC vs Bictegravir/FTC/TAF.;Timepoint(s) of evaluation of this end point: 24 weeks
