Colchicine Coronavirus SARS-CoV2 Trial (COLCORONA) (COVID-19)

Have you been diagnosed with COVID-19? Please help us stop the progression.

Sponsored by Montreal Heart Institute

The COLCORONA study is for people newly diagnosed with COVID-19 who are not sick enough to need hospitalization. To be eligible, one must be age 40 or older with one additional risk factor (listed below).

Should a patient qualify and enroll, they will take 0.5 mg of colchicine or a placebo for 30 days. Of note, this medication is used to treat gout and FMF. The goal is to see whether this common anti-inflammatory medication can help decrease the progression of disease. Research suggests that early use of this drug may help dampen inflammation that the body produces in response to COVID and enable patients to recover without being hospitalized.


Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.
