Effect of IL--1β Inhibition on Inflammation and Cardiovascular Risk

The purpose of this study is to evaluate the effects of IL-1β inhibition on safety, measures of systemic and vascular inflammation and endothelial function (all indicators of cardiovascular risk) in treated and suppressed HIV infected individuals This study will assess the safety and effects of canakinumab on endothelial function (assessed by flow-mediated vasodilation [FMD] of the brachial artery), vascular inflammation (assessed by FDG-PET/CT scanning), key inflammatory markers of cardiovascular disease (CVD) risk (high-sensitivity C-reactive protein [hsCRP]), interleukin-6 (IL-6), soluble CD163 (sCD163), D-dimer, T-cell and monocyte activation in the blood, and size of the HIV reservoir. 10 individuals will receive a single dose of 150mg canakinumab with follow-up for 12 weeks. In the second part of the study, 100 participants will be randomized (2:1 - canakinumab to placebo) and will be followed by for 36 weeks.

    Time frame: weeks 4, 8, 12, 18, 24, and 36.

    Change in absolute neutrophil count from baseline (entry) to follow-up at weeks 4, 8, 12, 18, 24, and 36.

  4. Change in Platelet Count From Baseline to Follow-up

    Time frame: weeks 4, 8, 12, 18, 24, and 36.

    Change in platelet count from baseline (entry) to follow-up at weeks 4, 8, 12, 18, 24, and 36.

  5. Change in Creatinine Count From Baseline to Follow-up

    Time frame: weeks 4, 8, 12, 18, 24, and 36.

    Change in creatinine count from baseline (entry) to follow-up at weeks 4, 8, 12, 18, 24, and 36.

  6. Change in AST From Baseline to Follow-up

    Time frame: weeks 4, 8, 12, 18, 24, and 36.

    Change in AST from baseline (entry) to follow-up at weeks 4, 8, 12, 18, 24, and 36.

  7. Change in ALT From Baseline to Follow-up

    Time frame: weeks 4, 8, 12, 18, 24, and 36.

    Change in ALT from baseline (entry) to follow-up at weeks 4, 8, 12, 18, 24, and 36.

Secondary outcomes

  1. Flow-Mediated Dilation (FMD)

    Time frame: Baseline and Week 12

    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

  2. Arterial Inflammation Measured at Baseline and Follow-up at Week 12

    Time frame: Baseline (entry) and Week 12

    Change From Baseline in Arterial Fluorodeoxyglucose (FDG) Uptake Assessed by FDG-PET/CT and reported as target-to-background (TBR) ratio to measure of vascular inflammation

    Time frame: Baseline, 4 weeks, 8 weeks, 12 weeks, and week 18

    D-Dimer will be assessed from baseline to weeks 4, 8, 12, and 18.

  4. Human Serum Amyloid A (SAA)

    Time frame: Baseline, 4 weeks, 12 weeks, and week 18

    SAA will be assessed from baseline to weeks 4, 12, and 18.

  5. Tumor Necrosis Factor Alpha (TNFa)

    Time frame: Baseline, 4 weeks, 12 weeks, and week 18

    TNFa will be assessed from baseline to weeks 4, 12, and 18.
