Intervention / Treatment |
---|---|
Experimental: Monotherapy
Monotherapy: darunavir/ritonavir (DRV/r) will be administered for 48 weeks.
|
Oral administration of tablet DRV 800 mg (2 tablets of 400 mg) once daily at the same time, within 30 minutes after food for 48 weeks

DRV/r along with 2 nucleoside reverse transcriptase inhibitors (NRTIs) will be administered for 48 weeks and whenever possible, participants should take these medications at the same time.
Switch of NRTIs will be allowed in the event of suspected toxicity/intolerance, providing this change can be linked to a documented adverse event (AE)/serious AE.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
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
|
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.

Baseline (Day 1 of Week 1) to Week 24

|
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.
