E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Efficacy To evaluate whether the oral FXIa inhibitor asundexian is superior to placebo on top of background antiplatelet therapy in reducing ischemic stroke in patients after an acute non-cardioembolic ischemic stroke or high-risk Transient ischemic attack (TIA)
Safety To compare the incidence of International Society on Thrombosis and Hemostasis (ISTH) major bleeding for asundexian and placebo on top of antiplatelet therapy in patients after an acute noncardioembolic ischemic stroke or high-risk TIA |
|
E.2.2 | Secondary objectives of the trial |
Efficacy To evaluate whether asundexian is superior to placebo on top of antiplatelet therapy in reducing the occurrence of composite and individual efficacy endpoints
Safety To compare asundexian and placebo on top of antiplatelet therapy with respect to individual bleeding endpoints
Net clinical benefit To further compare the benefit and risk of asundexian and placebo with respect to a composite of efficacy and safety endpoints |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Magnetic resonance imaging (MRI) Sub-study: to correlate baseline MRI findings with future events (e.g. covert brain infarction, recurrent strokes, intracranial bleeding), identify asundexian responders, further characterize the study population by MRI and add additional safety information on the asundexian 50 mg dose (to the Phase 2 study). |
