Change From Baseline to Week 24 in Brachial Artery Flow Mediated Vasodilatation (FMD): Median Change in FMD (%) [ Time Frame: Baseline (Day 1 of Week 1) to Week 24 ] [ Designated as safety issue: No ]
Brachial artery FMD is calculated as the percentage increase in brachial artery diameter with hyperemia (an increase in the quantity of blood flow to a body part) induced relative to the resting brachial artery diameter. Percentage of brachial artery diameter is measured as FMD diameter/basal diameter.
Change in brachial-artery-flow-mediated vasodilatation from baseline to Week 24 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: Yes ]

    The Homeostatic Model Assessment (HOMA) is a method used to quantify insulin resistance and beta-cell function. HOMA-IR is reflected in the diminished effect of insulin on hepatic glucose production. HOMA-IR is calculated as: (Glucose [mg/dL] X Insulin [pmol/L]) / (405 X 6.945). Higher scores indicate worse insulin resistance.

    The Framingham Risk Score is used to estimate the 10-year cardiovascular risk of a participant. It is calculated according to age, laboratory values of total cholesterol and HDL cholesterol, smoking status, and systolic blood pressure. The framingham risk score is calculated as: for males: 0 point (1 percentage) up to 17 points (30 percentages); whereas for females: 0 to 9 points (1 percentage) up to 25 points (30 percentage). Higher scores indicate high cardiovascular risk.

A Study to Compare Brachial Artery Reactivity and Cardiovascular Risk of a Treatment Simplification by Darunavir/Ritonavir (DRV/r) 800/100 mg Versus a Triple Combination Therapy Containing DRV/r in HIV-1 Infected Patients
A Randomised, Controlled, Open-Label Trial to Compare Brachial Artery Reactivity and Cardiovascular Risk of a Treatment Simplification by Darunavir/Ritonavir (DRV/r) 800/100 mg O.D. Versus a Triple Combination Therapy Containing DRV/r in HIV-1 Infected Subjects With Undetectable Plasma HIV-1 RNA on Their Current Treatments.

The purpose of this study is to compare change of brachial artery flow mediated vasodilatation using Darunavir/Ritonavir (DRV/r) 800/100 mg once daily as a monotherapy (use of a single medication) versus a triple combination therapy containing 2 nucleoside reverse transcriptase inhibitors (NRTIs) and DRV/r in Human immunodeficiency virus-1 (HIV-1) infected participants.

This is a Phase II, randomized (the study medication is assigned by chance), open-label (all people know the identity of the intervention), controlled, single centre study. The study consists of 3 phases including, the screening phase (4 weeks before administration of study medication), treatment phase (48 weeks), and the follow-up phase (4 weeks). In the treatment phase, HIV-infected participants who have not changed their first-line treatment of highly active antiretroviral therapy (HAART) for at least 8 weeks and have documented evidence of their HIV- ribonucleic acid (RNA) measurements being virologically suppressed (HIV-RNA less than 50 copies/mL) for at least 24 weeks prior to the screening, will be randomly assigned equally in two treatment arms: triple combination therapy arm (DRV/r 800/100 mg once daily plus 2 NRTIs) or monotherapy arm (DRV/r 800/100 mg once daily). Participants in the triple combination arm who are already on 2 NRTIs prior to randomization may remain on these or switch them at baseline, where the participants on the monotherapy arm will discontinue HAART at baseline and will start DRV/r 800/100 mg once daily. Safety evaluations will include assessment of adverse events, significant vital signs, and significant laboratory tests. The total duration of the study will be 56 weeks.
