Official title
Colchicine for Secondary Prevention After Ischemic Stroke (CHANCE-3 EX): a Multicenter, Double-blind, Placebo-controlled, Randomized Clinical Trial
Overview
The role of colchicine in the secondary prevention of ischemic stroke has not been determinded. This multicenter, randomized, double-blind, placebo-controlled, event-driven clinical trial of CHANCE-3 EX was aimed to assess the efficacy and safety of low-dose colchicine versus placebo on reducing the risk of recurrent ischemic stroke, myocardial infarction and vascular death in patients with minor-to-moderate ischemic stroke.
Interventions
- Drug Colchicine 0.5 mg
Oral colchicine will be initiated with a dose of 0.5 mg per day. - Drug Placebo colchicine
Oral placebo colchicine will be initiated with a dose of 0.5 mg per day.
Primary outcome measures
- First Event of ischemic stroke, myocardial infarction and vascular death [Time frame: From randomization to occurrence of the first event, with a median follow-up time of 24 months]
Secondary outcome measures (5)
- Ischemic stroke [Time frame: From randomization to event, with a median follow-up time of 24 months.]
- Myocardial Infarction [Time frame: From randomization to event, with a median follow-up time of 24 months.]
- Vascular death [Time frame: From randomization to death, with a median follow-up time of 24 months.]
- mRS 0-1 at 1 year or ≥1-point improvement in mRS score from baseline to 1 year [Time frame: At 1 year]
- mRS shift [Time frame: At 1 year]
Eligibility criteria
Inclusion criteria
- An age of 18-80 years old
- Minor-to-moderate ischemic stroke (NIHSS<15 at randomization; confirmed by CT or MRI)

Exclusion criteria

- A history of cirrhosis, chronic active hepatitis or severe hepatic disease
- Impaired hepatic (ALT or AST > three times the upper limit of normal range) or kidney (creatinine exceeding 1.5 times of the upper limit of normal range or eGFR less than 50 ml/min) function at randomization

- Severe non-cardiovascular comorbidity, active malignant tumors or terminal-stage illnesses, with a life expectancy of less than 2 years
- Clinically significant drug or alcohol abuse in the past year
- Any other conditions deemed unsuitable for participation in this study or inability to complete study procedures, including but not limited to mental disorders, cognitive or emotional impairments, or physical conditions that may compromise compliance with study protocols and follow-up visits
