Could a clot-busting drug help stroke patients on blood thinners? new trial aims to find out.
NCT ID NCT07621796
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the clot-busting drug tenecteplase is safe and effective for people having a stroke who took a blood thinner (DOAC) within the last 48 hours. About 660 adults will receive either tenecteplase or a placebo within 4.5 hours of stroke symptoms. The goal is to see if the drug reduces disability at 90 days without causing dangerous bleeding in the brain.

Inclusion Criteria: * Adults (18 years or older) with a suspected acute ischemic stroke and clearly disabling deficits * Presenting within 4.5 hours of last known well * Able to initiate intravenous thrombolysis within 4.5 hours of last known well * On recent DOAC therapy (dabigatran, apixaban, rivaroxaban, edoxaban) and known last dose taken within 48 hours from thrombolysis. Exclusion Criteria: * Current or history of intracerebral hemorrhage * Non-disabling deficits * Bleeding disorder (e.g. hemophilia) or advanced liver disease or known INR \> 1.7 within 6 hours * Use of therapeutic low molecular weight heparin or therapeutic dose heparin with elevated PTT * ASPECTS \< 6 or clear hypodensity on CT suggestive of completed infarct * Advanced kidney disease (eGFR \< 30 ml/min) * Known or suspected aortic dissection * Known or high suspicion for infective endocarditis * Surgery within 2 weeks * Intracranial or intraspinal surgery within 3 months * Active internal bleeding or gastrointestinal or urinary tract hemorrhage within 3 weeks * Intracranial neoplasm, arterio-venous malformation, or cavernous malformation * Major head trauma or ischemic stroke within 3 months * Known thrombocytopenia (platelets \< 100,000) * Planned endovascular treatment within 30 minutes of study drug administration (i.e., consent, randomization and administration of study drug must occur at least 30 minutes prior to groin puncture; standard care is not to be delayed and patients in whom endovascular therapy will start sooner will not be enrolled) * Comorbid condition with life expectancy of less than 3 months * Any condition that precludes thrombolytic therapy as determined by site principal investigator * Pregnancy
