About this trial

REDUCING INFLAMMATION IN ISCHEMIC STROKE WITH COLCHICINE, AND TICAGRELOR IN HIGH-RISK PATIENTS-EXTENDED TREATMENT IN ISCHEMIC STROKE.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Cerebral infarction (CI) proven by neuro-imaging (MRI or head-CT), immediately once the neurologic deficit is stabilized (investigator judgement) if the patient was on antiplatelet agent monotherapy after the qualifying event, or after 21 days if the patient was on clopidogrel plus aspirin after the qualifying event, or after 21 to 30 days if the patient was on ticagrelor plus aspirin after the qualifying event (TIA with documented ischemic lesion (MRI or CT) in the appropriate area corresponding to the symptoms will be considered CI, following the current definition)

Or TIA lasting more 10 minutes or more (with motor symptoms or aphasia/dysarthria or visual defect), with total resolution and no brain lesion on neuro-imaging (TIA) and with ipsilateral carotid stenosis that was revascularized (endarterectomy or stenting) or with ipsilateral, potentially causal intracranial stenosis ≥70%) if the patient was on antiplatelet agent monotherapy after the qualifying event, or after 21 days if the patient was on clopidogrel plus aspirin after the qualifying event, or after 21 to 30 days if the patient was on ticagrelor plus aspirin after the qualifying event

presence of carotid atherosclerotic stenosis (on the basis of carotid duplex, CTA, MRA, XRA - only the report will be required to document atherosclerotic disease) ipsilateral to the cerebral ischemic symptoms (stenosis defined by luminal narrowing ≥30%, judgement of the investigator)

or presence of atherosclerotic stenosis of another cerebral artery (documented vertebral artery stenosis, basilar artery stenosis, other intracranial artery stenosis) ipsilateral to the ischemic area (stenosis defined by luminal narrowing ≥30%, judgement of the investigator)

Disqualifiers

Colchicine treatment needed (e.g., gout, Mediterranean fever)

Hypersensitivity to ticagrelor or any of the excipients.

Hypersensitivity to colchicine or any of the excipients.

Major digestive disorders (chronic diarrhea, inflammatory disease of the digestive tract as uncontrolled ulcerative colitis or active Crohn disease)

Trial design

Design model

Factorial

Treatments tested in this trial

  • Colchicine 0.5 MG

    Drug

    Colchicine is a medication used to treat gout and Behçet's disease. In gout, it is less preferred to NSAIDs or steroids. Other uses for colchicine include the management of pericarditis and familial Mediterranean fever.

  • Ticagrelor 90mg

    Drug

    Ticagrelor, sold under the brand name Brilinta among others, is a medication used for the prevention of stroke, heart attack and other events in people with acute coronary syndrome, meaning problems with blood supply in the coronary arteries. It acts as a platelet aggregation inhibitor by antagonising the P2Y 12 receptor.

  • Aspirin 75-300mg

    Drug

    Also known as Aspirin, acetylsalicylic acid (ASA) is a commonly used drug for the treatment of pain and fever due to various causes. Acetylsalicylic acid has both anti-inflammatory and antipyretic effects. This drug also inhibits platelet aggregation and is used in the prevention of blood clots stroke, and myocardial infarction (MI).

Treatment groups

2,800 Participants
are divided into 4 treatment groups
Group A: Colchicine + TicagrelorExperimental treatment 2 interventions
Group B: Colchine + AspirineExperimental treatment 2 interventions
Group C: SOC + TicagrelorExperimental treatment 1 intervention
Group D: SOC + AspirineActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Number of Participants with nonfatal ischemic stroke

Sudden onset of focal neurologic symptoms related to impaired cerebral circulation. ASCOD phenotyping will be used. TIAs will not be part of strokes. However, any focal neurologic symptoms associated with positive DWI or hypodensity on the CT scan in an appropriate area in relation with these symptoms will be considered a cerebral infarction and be part of "strokes".

Time frame
36 months
2

Number of Participants with undetermined stroke

Sudden onset of focal neurologic symptoms related to impaired cerebral circulation. ASCOD phenotyping will be used. TIAs will not be part of strokes. However, any focal neurologic symptoms associated with positive DWI or hypodensity on the CT scan in an appropriate area in relation with these symptoms will be considered a cerebral infarction and be part of "strokes".

Time frame
36 months
3

Number of Participants with nonfatal myocardial infarction

* Fatal or nonfatal myocardial infarction (OMS.AHA/ACC definition) o Clinical symptoms + elevated troponin * Silent myocardial infarction following universal definition

Time frame
36 months
4

Number of Participants with urgent coronary or carotid revascularization following new symptoms

Revascularization Procedure * Coronary : Angioplasty or stenting or CABG * Carotid : angioplasty or stenting, surgical endarterectomy * Peripheral: angioplasty or stenting including aorta, surgical by-pass or endarterectomy of a peripheral artery.

Time frame
36 months

Secondary outcomes

1

Number of Participants with recurrent fatal and nonfatal ischemic stroke

Time frame
36 months
2

Number of Participants with urgent carotid revascularization following a new transient ischemic attack with negative neuro-imaging

Time frame
36 months
3

Number of Participants with fatal and nonfatal myocardial infarction

Time frame
36 months
4

Number of Participants with fatal and nonfatal myocardial infarction or urgent coronary revascularization following a new acute coronary syndrome

Time frame
36 months
