Registration Number
NCT06556446
Lead Sponsor
Insel Gruppe AG, University Hospital Bern
Brief Summary

DO-IT is an international, prospective observational registry evaluating whether the administration of intravenous thrombolysis (IVT) is safe and improves functional outcome in ischemic stroke patients with recent direct oral anticoagulant (DOAC) intake. For this purpose, information on 2800 adult participants experiencing an acute ischemic stroke will be obtained at several high-volume international stroke centers and divided into three groups: IVT with recent DOACs intake (DOAC+IVT), and recent DOAC intake not receiving IVT (DOAC) as well as anonymized patients without DOAC receiving IVT. The patients are followed up for 90 days after the index event. treatment recommendations from the described observations. The investigators hypothesize that also more liberal decisions for IVT in patients with recent DOAC intake are not associated with an increased risk for symptomatic intracerebral hemorrhage (sICH) and result in better functional outcome at 3 month.

Modified Rankin Scale from 0 (no disability) to 6 (death)

Number of Participants with symptomatic intracerebral hemorrhage (sICH)Within 36 hours after IVT

Defined as worsening of at least 4 points on the National Institutes of Health Stroke Scale and attributed to radiologically evident intracranial hemorrhage.

Secondary Outcome Measures
NameTimeMethod

Stroke severity (NIHSS)At 24 hours ±8 hours

National Institutes of Health Stroke Scale from 0 (no symptoms) to 39 (most severe symptoms)

Ischemic stroke volume at 24 hours (mL)At 24 hours ±8 hours
