Colchicine

This study aims to investigate whether TET2-associated clonal hematopoiesis of indeterminate potential (TET2-CHIP) can serve as a biomarker to guide precision use of colchicine in a population of clinically stable post-ACS patients receiving standard of care (SoC) therapy. Specifically, we will evaluate whether TET2-CHIP status predicts a differential response to colchicine. As a pilot study, it also aims to provide detailed data supporting design of further trial, such as sample size calculating, endpoint optimizing, etc.

This study wants to see if the medicine colchicine can help lower inflammation and reduce the chance of developing an irregular heartbeat (atrial fibrillation) after heart bypass surgery. Adults having coronary artery bypass surgery (CABG) can join. Participants will be randomly placed into one of two groups: one group will receive colchicine along with usual care, and the other will receive a placebo (a look-alike capsule with no medicine) along with usual care. Everyone will take a study capsule, and neither the patients nor the study team will know which capsule is being given. Everyone in the study will take study capsule, and neither the patients nor the study team will know who is receiving colchicine or placebo. Blood samples and health information will be collected before surgery; at 24, 48, 72, and 96 hours after surgery; and again at 10 days after surgery or at hospital discharge, whichever comes first. The investigators will look at inflammation marker levels, whether atrial fibrillation happens, and any side effects. This small study will help to generate effect size estimates and safety data that will help plan a larger study in the future.

This study aims to evaluate whether daily low-dose colchicine (0.5 mg), administered in addition to the standard secondary prevention regimen recommended in clinical guidelines after coronary artery bypass grafting (CABG), can further prevent graft failure after CABG through a prospective, randomized, double-blind, placebo-controlled clinical trial.

Data indicate that patients with intracerebral hemorrhage (ICH) are at high risk for thromboembolic events and disability that is not being sufficiently mitigated by current treatment strategies. This is aggravated by the cessation of antithrombotic medications for significant periods after hemorrhage. These findings highlight the need for novel treatments that modify the high risk for major vascular events and functional outcomes in ICH survivors. The objective of CoVasc-ICH 2 is to demonstrate that oral colchicine 0.5 mg daily is superior to placebo for improving the outcomes of ICH survivors with evidence or risk factors for atherosclerosis, when started within 72 hours from ICH onset.

The goal of this pilot trial is to to evaluate the preliminary effect of oral colchicine therapy on graft outcomes in patients underwent primary isolated CABG. The main questions it aims to answer is: 1. Whether the oral colchicine therapy may reduce the failure outcome of grafts after CABG. 2. Whether it is feasible to construct a muticenter powered trial to test the superiority hypothesis. Researchers will compare colchicine to none to see if colchicine works. Participants will 1. Take oral colchicine (0.5mg daily) therapy for 12 months after CABG. 2. Clinical follow-up at Month 1, 6, and 12 after CABG. 3. Protocol-driven CCTA at Week 1 and Month 12 after CABG.

Development of a new comprehensive method for perioperative prevention of atrial fibrillation paroxysms in cardiac surgery patients at the hospital stage. It is planned to recruit 70 patients who will undergo pericardial fenestration during the operation using the original technique during coronary artery bypass grafting (Patent No. 2647626 C1 Russian Federation), and will be prescribed colchicine (the drug "Colchicum-dispert") in the perioperative period in order to prevent the development of paroxysms of atrial fibrillation in the postoperative period, and 70 cardiac surgery patients operated on using the standard technique (without performing the pericardial fenestration procedure intraoperatively), receiving non-steroidal anti-inflammatory drugs in the postoperative period.

Colchicine (0.5 mg/day) was recommended by the U.S. Food and Drug Administration in 2023 for the anti-inflammatory treatment of coronary heart disease (CHD). However, colchicine is still not approved for CHD treatment in China. There is no large-scale clinical evidence that colchicine can be used to treat Chinese patients with CHD. Considering the low body weight of the East Asian population, it is unclear whether the recommended standard dose (0.5 mg/day) is suitable for Chinese patients. Therefore, we need to further explore the effects of different doses of colchicine on the efficacy and safety of clinical endpoints in the Chinese population with CHD. This study is a multicenter, prospective, randomized, controlled, double-blind, event-driven clinical study conducted in China. The primary objective of this study is to determine whether long-term treatment with different doses of colchicine reduces the incidence of cardiovascular events in Chinese patients undergoing PCI. The secondary objective is to determine the safety of long-term treatment with different doses of colchicine in this patient population.

This trial is designed to evaluate whether low-dose colchicine, in addition to standard treatment recommended by guidelines, further reduces the risk of major adverse cardiovascular events in patients with acute coronary syndromes (ACS) through a prospective, randomized, double-blind, placebo-controlled clinical trial.

The main purpose of the CHIPS trial is to evaluate the efficacy and safety of colchicine in heart failure with preserved ejection fraction (HFpEF) patients with inflammation, including the effects of colchicine on circulating inflammatory markers, cardiac structure, cardiac function, clinical symptoms and exercise capacity in HFpEF patients.
