E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluate the effect on immune recovery maintaining a triple antiretroviral therapy (elvitegravir / cobicistat 150/150 mg + tenofovir + emtricitabine alafenamide 10 mg 200 mg) versus combination therapy simplification (dolutegravir plus lamivudine or darunavir / cobicistat plus lamivudine) after 48 weeks Of treatment in HIV-infected patients with sustained undetectable viremia. |
Evaluar el efecto en la recuperación inmunológica del mantenimiento de una terapia antirretroviral triple (elvitegravir/cobicistat 150/150 mg + tenofovir alafenamide 10 mg + emtricitabina 200 mg) versus simplificación a biterapia (dolutegravir más lamivudina o darunavir/cobicistat más lamivudina) tras 48 semanas de tratamiento en pacientes con infección por el VIH con viremia indetectable de forma mantenida. |
|
E.2.2 | Secondary objectives of the trial |
Evaluate whether a triple therapy based on (elvitegravir / cobicistat 150/150 mg + tenofovir alafenamide 10 mg + emtricitabine 200 mg) will lead to a greater decrease in immune activation and inflammation compared to simplification to bitherapy (dolutegravir plus lamivudine or darunavir / Cobicistat plus lamivudine) in HIV-infected patients and sustained undetectable viremia. |
Evaluar si una triple terapia basada en (elvitegravir/cobicistat 150/150 mg + tenofovir alafenamide 10 mg + emtricitabina 200 mg) dará lugar a una disminución mayor de la activación inmunológica e inflamación comparado con la simplificación a biterapia (dolutegravir más lamivudina o darunavir/cobicistat más lamivudina) en pacientes con infección por el VIH y viremia indetectable de forma mantenida. |
