Overview

Heart failure (HF) is a chronic disease associated with multiple acute decompensations, which are the main cause of hospital admission above 65 years and two thirds of the high costs associated with the disease. Furthermore, in the patient they reflect a phase of clinical instability, with a higher risk of early readmission (20-30% at 30 days) and higher mortality (10-15% at 30 days and 30-40% at 1year). However, the investigators do not have treatments specifically aimed at this unstable phase, known as acute or decompensated (HF). It is known that, in this acute and unstable state, there is an increase in inflammatory parameters. Indeed, our group has recently demonstrated the relevance of the interleukin-1 axis, in particular IL-1beta and sST2 concentrations identified a worse prognosis regardless of HF phenotype. Colchicine, a widely available drug, has proven to be a powerful cardiovascular anti-inflammatory, acting on inflammasome and therefore inhibiting the production of IL1-beta.The study hypothesis is that colchicine administered early during the acute phase can promote stability in terms of biomarkers of cardiac function and new decompensations. For this it is designed a randomized, double-blind clinical study with two arms (colchicine 0.5 mg vs. placebo) initiated within the first 24 hours of hospitalisation and administered for 60 days, in patients with acute decompensated HF with either reduced or preserved LV ejection fraction.

The primary objective of the study is the reduction of NT-proBNP at two months of treatment. A secondary objective is to attain a greater clinical stability, in terms of reduction of new HF decompensations and need for diuretics, and symptoms improvement. The calculated population size is 278 patients. Follow-up visits will be carried out at discharge, 7 days, 4 weeks and 8 weeks after the hospital discharge. The potential of the study is very high given the high prevalence and clinical impact of HF hospitalizations, together with the absence of specific treatment for this phase of the disease. Therefore, in case of a positive result, this would mean a huge clinical, social and health benefits, as well as being an important therapeutic progress.

Patient who is taking colchicine for other indications (mainly chronic prescriptions for familial Mediterranean fever or gout). No washout period will be required for patients who have been treated with colchicine and have stopped treatment prior to randomization. 12. Patient with a history of allergic reactions or significant sensitivity to colchicine. 13. Chronic treatment with immunosuppressants, corticosteroids, interleukin-1 antagonists in the 6 months prior to inclusion. 14. Pregnant or lactating women, where pregnancy is defined as the state of a woman after conception and until the end of gestation, confirmed by a positive test result for human chorionic gonadotropin (hCG), or planned become pregnant or plan to breastfeed during study treatment or within 30 days of the end of study drug treatment. 15. Woman of childbearing potential who is unwilling to inform her partner of her participation in this clinical study or to use 2 effective contraceptive methods that are acceptable or to practice strict sexual abstinence (the investigator must assess the reliability of sexual abstinence and make it the preferred and usual lifestyle of the subject) during treatment with study drug (colchicine or placebo) and for an additional 30 days after the last dose of study drug.
