  • Percentage of participants with adverse events, serious adverse events and death [ Time Frame: 48 weeks ] [ Designated as safety issue: Yes ]
    Participants were monitored for adverse events, serious adverse events and death throughout the study.
  • Change from baseline in aortic distensibility [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Two axial, ECG-gated, steady state free precession (SSFP) 'cine' images were acquired during breath-hold to determine aortic distensibility. The first image was obtained at the level of the right pulmonary artery through the ascending and proximal descending aorta and the second through the distal aorta below the diaphragm. Imaging of the aorta also enabled evaluation of the plaque burden and additional vascular function measures including the arterial strain.
  • Change from baseline in plaque burden (aortic vessel wall area and carotid vessel wall area) [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    For assessment of atherosclerotic plaque burden of the aorta, vessel wall images of the aorta were acquired with an ECG gated double-inversion recovery (black blood) fast spin echo sequence applied breath-holding. Using an oblique sagittal image of the aorta as a pilot, serial axial images were acquired to cover a section of the descending thoracic aorta. The midpoint of the right pulmonary artery in cross section was used as the anatomical reference for the first slice in baseline and follow-up scans. For assessment of the atherosclerotic plaque burden in the carotids, vessel wall images were acquired with an axial ECG gated T2 weighted black blood sequence. The carotid bifurcation was used as the anatomical reference for all three imaging time points with axial slice planes acquired above and below the bifurcation region.
Measure: Safety, tolerability, and effect of monthly sc administration of ACZ885 on an integrated analysis of vascular function in subjects with atherosclerosis and T2DM or IGT [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: Yes ]

  • Change from baseline in pulse wave velocity and puse wave velocity error [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Utilizing the SphygmoCor Device, ECG leads placed at the carotid and femoral arteries provided the measure of the pulse wave at that particular arterial location. The distance between the two vascular beds divided by the pulse wave time shift provided a measure of the pulse wave velocity.
  • Change from baseline in plaque composition [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    During the carotid MRI acquisition, in addition to the T2 weighted ECG gated double inversion fast spin echo sequences T1 and PD weighted sequences were acquired. In combination with the T2 weighted images, the multi-contrast images were analyzed to determine regions of interest with contrast patterns consistent with the presence of necrotic lipid core, calcification and fibrous tissue.
  • Change from baseline in aortic strain [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Arterial strain was computed directly from the cine SSFP images and the change in lumen diameters over the cardiac cycle. The value was independent of pulse pressure.
  • Change from baseline in high sensitivity C-reactive protein (hsCRP) [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Blood samples were collected to analyze hsCRP.
  • Pharmacokinetics of ACZ885: serum concentration [ Time Frame: day 1, pre-dose, 4 hours, day 7, day 14, day 30, day 60, day 90, day 120, day 150, day 180, day 210, day 240, day 270, day 300, day 330, day 360, day 390, day 420, day 450 ] [ Designated as safety issue: No ]
    Blood serum samples were collected to analyze ACZ885 concentrations.
  • Change from baseline in fasting plasma glucose [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Blood samples were collected to analyze fasting plasma glucose.
  • Change from baseline in hemoglobin A1c (HbA1c) [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Blood samples were collected to analyze HbA1c.
  • Change from baseline in 2 hour glucose post oral glucose tolerance test (OGTT) [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]
    Blood samples were collected to analyze the 2 hour glucose post OGTT.
  • Change from baseline in beta cell function (HOMA-B) and insulin resistance (HOMA-R) [ Time Frame: baseline, 12 weeks, 48 weeks ] [ Designated as safety issue: No ]

    Blood samples were collected to analyze beta cell function and insulin resistance. Beta cell function and insulin resistance were calculated by the Homeostasis Model Assessments (of beta cell function (HOMA-B) and of insulin resistance (HOMA-IR)) as follows:

    HOMA-B: The product of 20 and basal insulin (µU/mL) levels divided by the value of basal glucose (mmol/L) concentrations minus 3.5 [i.e., HOMA-B = 20*basal insulin/(basal glucose-3.5)]. HOMA-IR: The product of basal glucose (mmol/L) and insulin (µU/mL) levels divided by 22.5 [i.e., HOMA-IR = basal glucose*basal insulin/22.5].

  • Measure: Assess the effect of ACZ885 on aortic pulse wave velocity, plaque composition, arterial strain [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: No ]
  • Evaluate the effect of ACZ885 on hsCRP [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: No ]
  • Assess the pharmacokinetics of ACZ885 in patients with atherosclerosis [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: No ]
  • Assess the effect of ACZ885 on glycemic parameters, including HbA1c and peak glucose levels 2 hours post the administration of an OGTT [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: No ]
  • Assess the effect of ACZ885 on beta cell function and insulin resistance [ Time Frame: 12 weeks and 48 weeks ] [ Designated as safety issue: No ]
