Efficacy of Colchicine in Secondary Prevention of Vascular Events and Renal Progression in Patients With Moderate Chronic Kidney Disease

The ColchiRen study is a phase 3, controlled, prospective, randomized, double-blind, and multicenter clinical trial. Its main objective is to demonstrate the benefit of low-dose colchicine treatment in secondary prevention of cardiovascular events in patients with moderate CKD. As a secondary objective, it aims to explore the potential beneficial anti-inflammatory effect on the progression of CKD.

Inclusion: Age between 18 and 99 years. Moderate chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) by the CKD-EPI formula between 30 and 59 mL/min/1.73 m²; History of a previous cardiovascular event:; Acute coronary syndrome. Admission for angina pectoris. Transient ischemic attack or non-cardioembolic ischemic stroke. Coronary revascularization. Peripheral vasculopathy, defined as: embolism or acute peripheral arterial ischemia, or the need for amputation or surgical revascularization; Finding of coronary artery disease on imaging test.

Exclusion: Current treatment with colchicine, or within the month prior to inclusion; Hospital admission for any cause within the 3 months prior to study inclusion; Immunosuppressive treatment within the 12 weeks prior to study inclusion; Chronic treatment with non-steroidal anti-inflammatory drugs (NSAIDs); Pregnancy and breastfeeding at the time of inclusion. Contraceptive methods are required for women of reproductive age. Women with no capacity for pregnancy are considered to be those with:; History of hysterectomy, bilateral salpingectomy, bilateral oophorectomy, or bilateral tubal ligation; Documented infertility. Postmenopausal women, defined as amenorrhea for more than 12 months without other medical cause. In case of doubt, confirmation with elevated follicle-stimulating hormone (FSH) levels is recommended; Women of reproductive capacity must use a method of contraception with proven effectiveness until 8 weeks after the end of the study. Acceptable methods include:; Intrauterine device (IUD) placement at least 6 weeks before study inclusion. Hormonal contraception with progestogens only, associated with ovulation inhibition: oral, injectable, or implantable, at least 6 weeks before study inclusion; Progestin-releasing intrauterine system (IUS) at least 6 weeks before study inclusion; Combined hormonal contraception (containing estrogen and progestogens) associated with ovulation inhibition: oral, intravaginal, transdermal, at least 6 weeks before study inclusion; Other contraceptive methods (sexual abstinence, barrier methods, spermicides, etc.) are not considered acceptable for participation in this study; thrombocytopenia <50,000 cells/μL during the month prior to inclusion; Neutropenia defined as <1500 cells/mcL during the month prior to inclusion; Treatment with CYP3A4 inhibitors and/or P-glycoprotein inhibitors (antivirals, azole antifungals, aminoglycosides, cyclosporine) in the month prior to their inclusion in the study; Active malignant neoplasm (except non-melanoma skin cancer or carcinoma in situ). Patients with a history of malignant neoplasm who have remained disease-free for the past 3 years may be included; Uncontrolled or symptomatic chronic inflammatory disease (rheumatoid arthritis, systemic lupus erythematosus, Crohn's disease, ulcerative colitis, etc.); Active infection with hepatitis B virus, hepatitis C virus, or human immunodeficiency virus; Poorly controlled hypertension (>160/90 mmHg) at the time of inclusion; Gastric ulcer; History of aplastic anemia diagnosed through bone marrow biopsy; History of allergy or intolerance to colchicine or any of its excipients (dihydrate calcium hydrogen phosphate, microcrystalline cellulose, anhydrous colloidal silica, magnesium stearate); Anemia defined as hemoglobin <10.5 g/dL during the month prior to inclusion; Liver cirrhosis of any cause, grade B or C according to Child-Pugh.
