Exclusion criteria
Exclusion criteria: 1. History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the result or the subject’s ability to participate in the study 2. Illness (including common colds) for the last 4 weeks before Visit 3 and Visit 4 3. Medical history of myocardial infarction (MI) or stroke within 12 months of screening 4. Ongoing or paroxysmal atrial fibrillation 5. Clinically overt heart failure 6. Hypertension defined as =180/100 mmHg 7. Diabetes mellitus 8.

Systemic autoimmune diseases requiring treatment 10. Cancer, excluding basal cell carcinoma, within the last five years 11. Medical PET, SPECT, abdominal or thoracic CT examination during the previous 12 months’ time period 12. Conditions contraindicating MRI such as, but not limited to, claustrophobia, having a history of brain or heart surgery and pacemaker implantation, permanent make-up, past or present occupation as metalworker or welder.

Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to assess the effects of four 250 mg 3G10 once monthly intravenous injections on monocyte function ex vivo. ;Secondary Objective: Primary objective The primary objective is to assess the effects of four 250 mg 3G10 once monthly intravenous injections on monocyte function ex vivo. Secondary objectives To assess functional effects of 3G10 on arterial inflammation in vivo To assess 3G10 effects on arterial stiffness To assess the safety and tolerability of 3G10 Exploratory objectives To assess the effects of 3G10 on heart function and LFR in a subgroup of the study population To study the pharmacodynamics of 3G10 by scavenger receptor and adhesion molecule expression on circulating monocytes and other circulating biomarkers To study the pharmacokinetics of 3G10 To further assess 3G10 effects on arterial stiffness over time To further assess functional effects of 3G10 on arterial inflammation in vivo To study the change in plasma protein patterns ;Primary end point(s): Change in TEM in monocytes isolated from treated subjects from baseline to visit 11;Timepoint(s) of evaluation of this end point: Baseline to visit 11 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary efficacy endpoints Change in TBRmax in common carotid arteries by fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG PET/CT) from baseline to Visit 11 Change in PWV (m/sec) assessed by Sphygmocor Xcel from baseline to Visit 11 Safety endpoints Safety and tolerability: AEs/SAEs, vital signs, physical examination, ECG and laboratory assessments including haematology, clinical chemistry and immunogenicity Exploratory endpoints Change from baseline in cardiac variables and LFR variables, as assessed by MRI, in a subgroup of the study population IgM anti-PC level, other circulating biomarkers, monocyte adhesion markers and scavenger receptors assessed by fluorescence-activated cell sorting (FACS) over time Pharmacokinetics: 3G10 serum levels Arterial stiffness variables, assessed by Sphygmocor Xcel TBRmean (carotid and aorta), TBRgluc (carotid and aorta) and TBRmax (aorta) assessed by 18F-FDG PET/CT Change in protein pattern from baseline to Visit 11 as assessed by proteomics measurements ;Timepoint(s) of evaluation of this end point: Secondary efficacy endpoints are evaluated from baseline to Visit 11 Safety endpoints: Adverse events (AE) will be assessed from administration of study drug until end of study visit. ECG will be assessed at screening and pre-dose as well as post dose at dosing visits. Vital signs and physical examination will be assessed during all visits to the clinic. Safety blood samples will be assessed at all visit to the clinic. Immunogenicity will be assessed pre-dose at each dosing visit dosing and at the end of study visit. Exploratory endpoints will be presented showing observed values and changes from baseline at each available visit/assessment | — |
