General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study is to evaluate clinical efficacy of treatment with colchicine 0.5mg once daily as compared to placebo in patients with stable coronary artery disease on the incidence of first occurrence of the composite of cardiovascular death, myocardial infarction, ischemic stroke, or ischemia-driven revascularization.
|
||
Protection of trial subjects |
Colchicine 0.5mg once daily is the reduced dosage recommended by the 2012 American College of Rheumatology Guidelines for Management of Gout and the FDA prescription information for Colcrys in patients with impaired renal function and for patients with concomitant use of CYP3A4 or P-glycoprotein inhibitors. (70, 71)
A 30-day open label colchicine run-in period will largely filter out those with side effects occurring after initiating colchicine. By only including patients with normal renal function (eGFR ≥ 50 ml/min/1.73m2 or a serum creatinine > 150 μmol/L) and by using low-dose colchicine, adverse effects are likely to be reduced to a minimum as in the pilot LoDoCo trial.
General practitioners and pharmacies will be informed on the study participation of their patients. They will be asked to report events or adverse reactions to the trial medication. Second, they will be asked to interrupt the trial medication during administration of known CYP3A4 inhibitors and monitor renal function closely in situations where it is expected that this might be impaired (e.g. diarrhoea or the start of nephrotoxic medicine).

Recruitment
|

Recruitment details |
Recruitment started in August 2014 in Australia and October 2016 in The Netherlands. Recruitment ended December 3rd 2018 when the 5522th participant was randomized in The Netherlands. | ||||||||||
Pre-assignment

Screening details |
On the assumption that 10% of participants would report early intolerance to therapy, the trial aimed to enrol 6053 screened patients, expecting 5447 to be randomized (divided over both continents) and then followed for a median of 3 years. | ||||||||||

Notes [2] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
