Canadian Study of Arterial Inflammation in Patients With Diabetes and Vascular Events: EvaluatioN of Colchicine

Plain-language summary
Cardiovascular Disease (CVD) is a leading cause of death in the developed world. Atherosclerosis causes plaques in the blood vessels and is a common form of CVD. Inflammation is now recognized as a major cause of atherosclerosis. Therapies that target inflammation are being examined as a potential treatment option. Imaging to detect inflammation may be a solution to understand mechanisms and to optimize patient selection and outcomes for these drugs. Fluorodeoxyglucose (FDG) PET imaging can detect inflammation in the plaque and identify patients vulnerable to plaque rupture which cause events such as myocardial infarctions (MI) and strokes. The primary objective of this proposal(CADENCE) is to determine if the drug colchicine has an effect on plaque inflammation in patients at high risk for events (patients with diabetes or pre-diabetes and recent myocardial infarction, stroke or transient ischemic attacks (TIAs)). This mechanistic and proof-of-concept study will set the stage for future studies that will determine if inflammation imaging can be integrated into clinical practice to personalize decisions for anti-inflammation therapies.

Inclusion criteria
. Type 2 Diabetes (on diet, oral hypo-glycemic agents and/or insulin) or pre-diabetes (defined by Diabetes Canada as HbA1C=6.0-6.45% or increased fasting blood sugar (FBS) (6.1-6.9 mmol/L) or impaired glucose tolerance);
. suffered a recent cardiovascular event (≤120 days post ACS (i.e. STEMI or nonSTEMI) or TIA/stroke with associated large vessel atherosclerotic disease confirmed on US, CT or MRI;
. stable symptoms and hemodynamics;
. age ≥18 years;
. given informed consent. Standard definitions will be used for STEMI, NSTEMI, and for ischemic stroke confirmed by CT or MRI and TIA confirmed by a neurologist.
Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
