Summary

Perioperative myocardial injury and major adverse cardiovascular events (MACE) are common causes of morbidity and mortality in patients at increased cardiovascular risk undergoing non-cardiac surgery. However, research in recent years has yielded limited preventive and therapeutic measures for myocardial injury/MACE. Recent studies in patients with chronic and acute coronary artery disease have shown that colchicine administration can reduce the risk of cardiovascular events. These encouraging results in non-surgical patients ask for a similar investigation in patients undergoing major non-cardiac surgery. The aim of the proposed study is to investigate the effects of perioperative colchicine administration on the incidence of myocardial injury/MACE.

Detailed description

This double-blind, placebo-controlled study is conducted at the Cantonal Hospital St. Gallen and the University Hospital Basel, Switzerland. The investigators intend to expand the participant recruitment to other centers. Inclusion criteria encompass patients' cardiovascular risk profile and vascular, orthopedic, visceral, and thoracic surgical procedures with a high risk as determined by the recognized incidence of troponin dynamics. Patients are informed during preoperative consultation and provide consent prior to randomization to the colchicine or placebo groups. The preoperative assessment includes medical history, medication use and physical capacity. Baseline values and cardiac biomarkers, are determined through routine laboratory tests. Study medication is administered from the evening before surgery until the third postoperative day. Daily high-sensitivity cardiac troponin T (hs-cTnT) testing is performed until the fourth day. Visits monitor primary, secondary, and safety endpoints, with standard treatment for complications. Post-hospitalization, cardiovascular events will be recorded until postoperative day 30 and for one year post-surgery to assess long-term outcomes. The primary objective is to evaluate the efficacy of perioperative colchicine administration in cardiac-risk patients undergoing major non-cardiac surgery, with the aim of reducing the myocardial injury incidence until postoperative day 4 and mitigate postoperative MACE until postoperative day 30. Secondary objectives include whether perioperative administration of colchicine reduces new-onset atrial fibrillation incidence postoperatively (until discharge) compared to placebo, to quantify the maximum increase in postoperative hs-cTnT concentrations until postoperative day 4 and to assess the impact of perioperative colchicine administration on long-term survival and morbidity (composite of MACE) after one year. The safety objectives are the incidence of gastrointestinal adverse events and clinically adverse events attributable to the administration of colchicine.

Interventions

Type	Name	Description
DRUG	Colchicine	Colchicine Group: IMP = Colchicine (0.5 mg, enteral) first application in the evening before day of surgery, following a 1-0-1 regimen until the third postoperative day, ending with the application of the ninth dose. Colchicine tablets are provided as 1 mg tablets with a score, which must be divided before ingestion.
DRUG	Placebo	Placebo Group: Placebo (identical to IMP in appearance and application) first application in the evening before day of surgery, following a 1-0-1 regimen until the third postoperative day, ending with the application of the ninth dose. Placebo tablets are provided as tablets with a score, which must be divided before ingestion.
