Recruitment status was: Recruiting
|Study Design:||Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase IV, Randomized, Open Label, Crossover, Intervention Trial to Investigate the Effect of the Switch of Lopinavir/Ritonavir to Raltegravir on Endothelial Function, Chronic Inflammation, Immune Activation and HIV Replication <50 Copies/ml|
- Change in flow mediated dilatation (FMD) of the brachial artery [ Time Frame: week 8, week16 ]Change in flow-mediated dilatation (FMD) of the brachial artery after 8 weeks of raltegravir treatment as compared to the control group (treatment with lopinavir/ritonavir)
- Change in markers of chronic inflammation [ Time Frame: Baseline, week 2, week 4, week 8, week 10, week 12 and week 16 ]
- Change in markers of immune activation [ Time Frame: Baseline, week 2, week 4, week 8, week 10, week 12 and week 16 ]
- Change in markers of endothelial function [ Time Frame: Baseline, week 2, week 4, week 8, week 10, week 12 and week 16 ]
- Changes in plasma HIV-RNA below 50 copies/ml [ Time Frame: Baseline, week 8, week 16 ]
|Study Start Date:||January 2012|
|Estimated Study Completion Date:||December 2014|
|Estimated Primary Completion Date:||October 2014 (Final data collection date for primary outcome measure)|
Active Comparator: Raltegravir
At baseline, lopinavir-ritonavir will be switched to raltegravir (cross-over after 8 weeks).
Switch of lopinavir/ritonavir to raltegravir 400 mg BID (duration 8 weeks)
Other Name: Isentress
No Intervention: Lopinavir/ritonavir
Subjects will continue lopinavir/ritonavir (cross-over after 8 weeks)
Fixed dose combination lopinavir/ritonavir (LPV/r) is a widespread used antiretroviral drug belonging to the class of protease inhibitors (PIs). PIs are associated with an increased risk of myocardial infarction. However, data is available suggesting increased levels of plasma lipids are not the sole explanation for this observation. Treatment with LPV/r might lead to a decrease of endothelial function as well, thus explaining the increased risk of myocardial infarction besides increased plasma lipids. Raltegravir is a registered antiretroviral drug with no known cardiovascular side effects. We hypothesize that switching LPV/r to raltegravir in HIV-infected patients with suppressed plasma viral load (<50 copies/ml) will lead to an improvement of endothelial function.
- First, to assess the effect of the switch of lopinavir/ritonavir to raltegravir on endothelial function.
- Second, to assess the effect of the intervention mentioned above on markers of endothelial function; immune activation; chronic inflammation; and, on plasma HIV-RNA below the cut-off of 50 copies/ml.
