Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In this study, the investigators hope to determine if colchicine decreases the incidence of MINS in high risk surgical patients undergoing non-cardiac surgery and optimally establish colchicine as a viable therapy to improve perioperative cardiovascular outcome in those patients.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To support early detection and diagnosis of myocardial injury in the perioperative setting, myocardial injury after non-cardiac surgery (MINS) has been recognized as an important prognostic marker independently associated with mortality and significant morbidity in the perioperative period. MINS is defined as prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. Perioperative screening and monitoring of MINS is recommended by the most recent 2016 Canadian Cardiovascular Society (CCS) Guidelines. One study found of the MINS patients, only 41.8% of which filled universal definition of MI. This may suggest that screening for MINS in the Perioperative setting by detecting post-operative troponin rise is an important marker to prompt further investigation and closer monitoring.
However, despite efforts in recognition and establishment of MINS, there is still no consensus for the optimal management of MINS in addition to routine cardiac risk stratification. Common MI management options may be complicated by post-operative changes such as anemia, hypotension, hypoxemia, and use of routine anti-platelet and anticoagulation agents and invasive intervention is associated with high risk of complication and mortality in the perioperative period.
Colchicine is an alkaloid anti-inflammatory drug with well-established safety and adverse effect profile in various clinical settings including pericarditis and gout flare. Pharmacologically, colchicine inhibits beta-tubulin polymerization into microtubules, preventing activation and migration of neutrophils to achieve its anti-inflammatory effect. Clinically in the cardiac surgery patient population, colchicine has been shown in multiple meta-analyses to be efficacious in preventing post-operative atrial fibrillation, in treatment and prevention of pericarditis and post-pericardiotomy syndrome. In patients who are high risk for cardiovascular events, systemic review has shown reduction in cardiovascular mortality and myocardial infarction in some studies. Colchicine is an ideal agent in the perioperative period as it does not increase the risk of major bleeding, hepatic and renal toxicity, and there is only gastrointestinal discomfort at high doses.
In this study, the investigators hope to determine if colchicine decreases the incidence of MINS in high risk surgical patients undergoing non-cardiac surgery and optimally establish colchicine as a viable therapy to improve perioperative cardiovascular outcome in those patients.
Research Question: In the current clinical setting, is a larger, multi-centre randomised controlled trial comparing effect of perioperative oral colchicine administration versus placebo on incidence of MINS feasible?
This pilot study will inform many aspects of the future multi-centre trial. The pilot study will provide information on the recruitment rate of eligible patients and incidence of MINS on the recruited patient, which will allow the investigators to determine the sample size required in the large multi-centre trial to detect clinically relevant differences.
The pilot study will also provide information on the operational aspect of clinical trial, including initial patient enrolment and consent processes, data collection from electronic chart review. This will help refine the process and improve efficiency of the larger trial.
Lastly, information collected on side-effects of study drug (colchicine) would improve timely detection and treatment of the associated side effects (GI, myopathies, and blood dyscrasias), as well as expected drop-out rate from the larger trial due to intolerance of these side effects.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Colchicine Group
Administration of oral colchicine at 0.6 mg 1 hour prior to surgery, then 0.6 mg twice daily starting on the night after surgery for 7 days or until discharge from hospital, whichever occurs earlier. For patient under 60kg in body weight, daily dose will be 0.6 mg once daily. Medical and surgical management of the participant will be carried out under each institute's standard clinical practice.
Colchicine 0.6 mg
Oral colchicine given at 0.6 mg 1 hour prior to surgery, then 0.6 mg twice daily starting on the night after surgery for 7 days or until discharge from hospital, whichever occurs earlier. For patient under 60kg in body weight, daily dose will be 0.6 mg once daily. Medical and surgical management of the participant will be carried out under each institute's standard clinical practice.
Placebo Group
Participants allocated to the control group will receive a placebo pill at the same dosing regimen as with treatment group. Perioperative and surgical care will not be different from standard clinical practice.
Placebo oral tablet
Placebo oral tablet given at 0.6 mg 1 hour prior to surgery, then 0.6 mg twice daily starting on the night after surgery for 7 days or until discharge from hospital, whichever occurs earlier. For patient under 60kg in body weight, daily dose will be 0.6 mg once daily. Medical and surgical management of the participant will be carried out under each institute's standard clinical practice.
