TICA-CLOP STUDY: Ticagrelor Versus Clopidogrel in Acute Moderate and Moderate-to-Severe Ischemic Stroke, a
Randomized Controlled Multi-Center Trial
Randomized Controlled Trial CNS Drugs. 2025
Jan;39(1):81-93. doi: 10.1007/s40263-024-01127-7.
Abstract
Background: Many studies evaluated the efficacy
and safety of ticagrelor versus clopidogrel in patients with ischemic stroke; none of these trials included North African participants, and all of these trials comprised only participants who experienced transient ischemic attack
(TIA) or minor stroke.
Objectives: We compared the efficacy and safety of ticagrelor versus clopidogrel in patients with first-ever noncardioembolic moderate or moderate-to-severe ischemic stroke.
Methods: Our trial involved 900 first-ever noncardioembolic patients with acute ischemic stroke (AIS) who randomly
received either loading and maintenance doses of ticagrelor or clopidogrel within the first 24 hour of stroke onset.
Results: We involved 900 patients in the intention-to-treat analysis. A total of 39 (8.7%) patients in ticagrelor arm
and 62 (13.8%) in clopidogrel arm experienced a new stroke [hazard ratio (HR) 0.46; 95% confidence interval (CI) 0.34-0.83; P value = 0.006]. A total of 57 (12.7%) patients in ticagrelor group and 80 (17.8%) patients in clopidogrel
group experienced composite of new stroke, myocardial infarction (MI), or death due to vascular insults (HR
0.51; 95% CI 0.43-0.82; P value = 0.004). Participants who received ticagrelor experienced less frequent unfavorable outcomes. We found no significant variation between our study's two arms concerning the hemorrhagic and non-hemorrhagic complications.
Conclusion: Patients with noncardioembolic moderate or moderate-to-severe ischemic stroke who received ticagrelor within the first 24 h after ischemic stroke had better clinical outcomes based on recurrent stroke rates and unfavorable modified Rankin Scale (mRS) rates compared with those who received clopidogrel. There were no significant variations between ticagrelor and clopidogrel regarding hemorrhagic and non-hemorrhagic complications.
