Clinical Trial Summary

This study is two-center, prospective, randomized, open-label, controlled, investigator-sponsored study that aims to investigate the efficacy of low-dose colchicine in preventing recurrent stroke in the patients with acute atherothrombotic minor-to-moderate ischemic stroke during hospitalization.


Description:

This study is two-center, prospective, randomized, open-label, controlled, investigator-sponsored study that aims to investigate the efficacy of low-dose colchicine in preventing recurrent stroke in the patients with acute atherothrombotic minor-to-moderate ischemic stroke during hospitalization. Patients who were eligible to the inclusion criteria and ineligible to the exclusion criteria will be randomly assigned into two groups by a 1:1 ratio. Patients in one arm will receive colchicine initiated with a dose of 0.5 mg per day during on days 1 through 14. Study visits will be performed on the day of randomization and at discharge. The outcomes were stroke, neurological deterioration, сombined endpoint events (stroke, myocardial infarction and death), bleeding during 14 days of follow-up in an intention-to treat analysis.

Eligibility Inclusion Criteria: 1. Signed informed consent form by patient prior to any study-specific procedure. 2. Patient age over 18 years 3. Presence of ipsilateral lesion of the extracranial artery =50% according to the European measurement method ECST or its occlusion, as well as stenosis < 50% with signs of morphological instability of the atherosclerotic plaque (ulceration, hemorrhage into the plaque, intimal flotation, mural thrombus, etc.). 4.

Concomitant severe degenerative disease of the nervous system. 9. Concomitant inflammatory or autoimmune disease. 10. Dementia, established mental illness. 11. History of malignancy, known hepatitis B or C, or HIV infection. 12. Swallowing impairment interfering with oral administration of the study drug. 13. Pregnancy or breastfeeding. Women of child-bearing potential who are not willing to use a medically accepted method of contraception that is considered reliable in the judgment of the Investigator. 14. Participation in another clinical study with an investigational product at any time during the 30 days prior to randomization 15. Previous enrolment or randomization in the present study. 16. Decrease renal function with creatinine clearance < 30 ml/min. 17. Presence of contraindications to taking colchicine, acetylsalicylic acid and clopidogrel.

Intervention

Drug:
Colchicine
Oral colchicine will be initiated with a dose of 0.5 mg per day during 14 days. Acetylsalicylic acid was used as an antiplatelet agent (300 mg on days 1 and continuing with 100 mg/day).
Clopidogrel
Dual antiplatelet therapy includes ASA (300 mg on days 1 and continuing with 100 mg/day) and clopidogrel (300 mg on days 1 and continuing with 75 mg/day).

Outcome

Type Measure Description Time frame Safety issue
Primary Any new stroke events Incidence of any new ischemic stroke. any time within 14 days
Primary Neurological deterioration Neurological deterioration, defined as an increase in The National Institutes of Health Stroke Scale (NIHSS) of 2 or more. The NIHSS provides a quantitative measure of stroke-related neurologic deficit. The higher the score, the more severe the neurological deficit. any time within 14 days
Secondary New vascular events Incidence of any new vascular events, including ischemic stroke, myocardial infarction and vascular death any time within 14 days
Secondary Bleeding event Bleeding event that is categorised as severe according to GUSTO (Global Utilization Of Streptokinase And Tpa For Occluded Arteries) bleeding criteria. any time within 14 days
Secondary Positive functional outcome A positive functional outcome within 14 days is determined if the Modified Rankin Score (mRS) improves to 0-1 and/or Rivermead Mobility Index (RMI) to 14 -15 points and/or Rehabilitation Routing Scale 0 -1 points.
The mRS is a 6 point disability scale with possible scores ranging from 0 to 5. A separate category of 6 is usually added for patients who expire.
The RMI includes fifteen mobility items. A maximum score of 15 is possible: higher scores indicate better mobility performance.
The rehabilitation routing scale is needed by the doctor to understand whether the patient requires rehabilitation. The maximum number of points is 6. The more points the patient scores, the more severe his condition.
any time within 14 days
