E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the virologic efficacy of a maintenance regimen with
RPV+DRV/r in HIV+ subjects with a previous antiretroviral treatment and a full HIV-RNA suppression. |
Obiettivo primario dello studio è la valutazione dell’efficacia virologica di un regime di mantenimento con RPV + DRV/r in soggetti HIV+ già sottoposti a terapia antiretrovirale e con carica virale soppressa. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate VACS index modification in subjects treated in two groups, at Weeks 48
and 96, as compared to the baseline;
• To evaluate differences of markers of tubulopathy (RBP, RBP/creatinine, plasmatic and
urinary phosphate, albuminuria) in two groups at week 12, 48, and 96 as compared to the
baseline; we report urinary RBP abnormalities in some patients treated with tenofovir, in some
studies, and the significance of RBP as an indirect marker of tubular damage;
• To evaluate differences of markers of lipid metabolism (total cholesterol, HDL and LDL cholesterol, triglycerides);
• To evaluate differences of markers of bone metabolism (osteocalcin, CTx) as compared
to baseline;
• To evaluate darunavir and rilpivirine plasma exposure (Ctrough) as a determinant of
virological failure. |
• Valutazione della modificazione del VACS index nei due gruppi, confronto tra essi e alle Week 48 e 96 rispetto al baseline;
• Valutazione della differenza in termini di markers di tubulopatia (RBP, RBP/creatinina; fosfato plasmatico; fosfaturia; albuminuria; eGFR) nei due gruppi alle week 12, 48 e 96, confrontato con il baseline; si segnala il riscontro di alterazioni della RBP urinaria (Retinol Binding Protein) in soggetti trattati con tenofovir, e il suo conseguente significato come indicatore indiretto di danno tubulare;
• Valutazione della differenza in termini di markers di metabolismo osseo (osteocalcina, CTx);
• Valutazione della differenza in termini di profilo lipidico (colesterolo totale, HDL, LDL, trigliceridi);
• Valutazione della concentrazione plasmatica (Ctrough) di RPV e DRV nella determinazione di fallimento virologico. |
