The COLCOT clinical trial demonstrates that it is possible to
reduce the risk of cardiovascular events with a low-cost drug already available.
The Montreal Heart Institute (MHI) announced on November 16th,
2019 the results from the COLchicine Cardiovascular Outcomes Trial (COLCOT).
The clinical trial compared colchicine to placebo on top of standard of care in preventing
ischemic cardiovascular events in patients who recently suffered from a heart attack (myocardial infarction).
In this study, patients receiving colchicine 0.5mg daily had a significantly lower rate of ischemic
cardiovascular events (first and recurrent) than those on placebo¹.
These results were published earlier today in the prestigious New England Journal of Medicine (NEJM)
and were simultaneously presented at the American Heart Association (AHA) Late-Breaking Scientific Session.
In summary, colchicine significantly reduces the risk of a first ischemic cardiovascular event and of total
ischemic cardiovascular events by 23% and 34%, respectively, in addition to standard of care in patients with
a recent myocardial infarction (MI).
The primary efficacy endpoint was a composite of cardiovascular death, resuscitated cardiac arrest, MI,
stroke or urgent hospitalization for angina requiring coronary revascularization¹.
Patients were also treated according to national guidelines that included the intensive use of statins¹.
The trial demonstrated that the treatment with colchicine reduced by:
• 23% the risk of a first event of the primary efficacy endpoint;
• 34% the risk of total (first and recurrent) events of the primary efficacy endpoint;
• 29% the risk of a first event of the primary efficacy endpoint in patients who adhered to the protocol.
“The data from the COLCOT trial underscore the potential of colchicine as an efficient and critically needed therapy
for reducing inflammation post-myocardial infarction to improve patient cardiovascular outcomes.” said Dr. Jean-Claude Tardif,
Director of the Research Center at the Montreal Heart Institute, Professor of Medicine at the University of Montreal,
and COLCOT primary investigator. Dr Tardif also outlines that by repurposing older drugs, the COLCOT trial exemplifies
how to bring innovation in the field of life and health sciences in a time- and cost-effective manner.
About the COLchicine Cardiovascular Outcomes Trial (COLCOT)
Colchicine is an orally administered anti-inflammatory medication that is currently indicated
for the management of gout, and familial Mediterranean fever in Canada. Initiated by a researcher from
the Montreal Heart Institute, COLCOT was a randomized, double-blind, clinical trial comparing colchicine 0.5 mg
once daily with placebo on top of standard of care.
The trial took place across 167 research sites in 12 countries.
The colchicine used in this trial was provided by Pharmascience Inc., Canada.
The Montreal Health Innovations Coordinating Center (MHICC) coordinated the study
and conducted the statistical analyses. Study endpoints were evaluated and confirmed
by an independent committee composed of cardiologists and neurologists.
The trial was overseen by an independent data safety monitoring board.
Within 30 days of their MI, the 4,745 COLCOT patients were randomized to
receive colchicine 0.5mg daily or placebo, on top of their standard of care.
They have been subsequently followed for a median of 23 months¹.
