Study Description

Brief Summary:

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. 20 individuals will receive a single dose of 150mg canakinumab with follow-up for 18 weeks.

Arms and Interventions

Arm	Intervention/treatment
Safety Arm; In Stage 1: all 10 subjects will receive 150 mg Canakinumab subcutaneous injection. This will be a preliminary safety study (before Stage II).	Drug: Canakinumab; 150mg Canakinumab received subcutaneously; Other Name: IL--1β

Placebo Comparator: Placebo; In Stage II: About 33 subjects will receive 150mg placebo subcutaneous injection	Drug: Placebo; 150mg Placebo received subcutaneously

Outcome Measures

Primary Outcome Measures :

1. Number of Adverse Events at week 1 as a measure of safety [ Time Frame: Week 1 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose
2. Number of Adverse Events at week 2 as a measure of safety [ Time Frame: Week 2 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose
3. Number of Adverse Events at week 4 as a measure of safety [ Time Frame: Week 4 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose, CD4 count, HIV-1 RNA
4. Number of Adverse Events at week 8 as a measure of safety [ Time Frame: Week 8 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose, CD4 count, HIV-1 RNA
5. Number of Adverse Events at week 12 as a measure of safety [ Time Frame: Week 12 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose, CD4 count, HIV-1 RNA
6. Number of Adverse Events at week 18 as a measure of safety [ Time Frame: Week 18 ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose
7. Number of Adverse Events at baseline as a measure of safety [ Time Frame: Baseline ]
   Toxicities will be assessed and adverse events will be recorded at the study visit, including abnormal lab values for the following list of labs: CBC, AST, ALT, bilirubin, creatinine, glucose

Secondary Outcome Measures :

1. Change in brachial artery flow-mediated vasodilation (FMD) [ Time Frame: Baseline, 12 weeks ]
   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. Change From Baseline in Arterial Fluorodeoxyglucose (FDG) Uptake Assessed by FDG-PET/CT as a measure of vascular inflammation [ Time Frame: Baseline, 12 weeks ]
   Assessed by FDG-PET/CT scanning
3. Rate of change in inflammatory markers of CVD risk [ Time Frame: Baseline, 4 weeks, 12 weeks, 18 weeks ]
   Linear mixed modelling will be used to estimate rates of change over the 18 weeks of treatment. Inflammatory markers: 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
