Within the worldwide CONVINCE trial, offered right this moment (15 Might 2024) on the European Stroke Group Convention (ESOC 2024), anti-inflammatory therapy with long-term colchicine didn’t scale back charges of recurrent stroke and cardiovascular occasions in sufferers with non-cardioembolic stroke within the major intention-to-treat evaluation.

Decreased occasion charges in secondary analyses, and within the subgroup of sufferers with coronary artery illness, assist trials which reported profit in coronary illness and should inform future secondary prevention trials in stroke.

Irritation performs an vital position within the pathophysiology of atherosclerosis. Over the previous years, a number of trials have proven that anti-inflammatory therapy reduces recurrent vascular occasions in coronary artery illness, whereas no such proof is on the market for stroke. Colchicine is a longtime drug to cut back inflammatory response and broadly out there at low price.

CONVINCE was a global, randomized, open-label trial designed to check whether or not long-term colchicine (0.5 mg/day) along with normal of care reduces recurrent stroke or cardiovascular occasions in sufferers with non-cardioembolic ischemic stroke or high-risk transient ischemic assault (TIA).

The first endpoint was a composite of first recurrent ischemic stroke, myocardial infarction, cardiac arrest or hospitalization for unstable angina. Over a interval of virtually six years and regardless of constraints imposed by the COVID-19 pandemic, 3,154 sufferers have been randomized and adopted for a median of 34 months.

Within the intention-to-treat evaluation, the first endpoint occurred in 153 sufferers randomized to colchicine (9.8%) in contrast with 185 on typical care (11.8%), which translated into incidence charges of three.32 versus 3.92/100 person-years. The adjusted hazard ratio was 0.84 (95% confidence interval 0.68-1.05, p=0.12).

Decreased ranges of CRP within the colchicine group confirmed the anti-inflammatory impact of therapy with colchicine. Within the pre-specified on-treatment evaluation, in addition to within the subgroup of sufferers with a historical past of coronary artery illness, considerably diminished charges of recurrent stroke or cardiovascular occasions have been noticed.

Professor Peter Kelly, the principal investigator of CONVINCE and Scientific Full Professor at College Faculty Dublin Faculty of Drugs and Mater Misericordiae College Hospital, mentioned, “Though the first evaluation was impartial, the alerts of advantage of colchicine on secondary analyses are consistent with findings from earlier trials and point out the potential of colchicine in prevention after stroke.

“In CONVINCE, the COVID pandemic diminished the deliberate follow-up time, which led to under-powering for the first evaluation by 8%. Additional trials are wanted in all stroke subtypes, however with specific concentrate on sufferers with goal proof of atherosclerosis.”

In conclusion, though the first endpoint was impartial, the outcomes of CONVINCE assist the speculation that long-term anti-inflammatory remedy with colchicine could scale back recurrent stroke and cardiovascular occasions particularly in stroke sufferers with atherosclerosis.
