Trial Outcomes & Findings for Safety of Intravenous Thrombolysis for Wake-up Stroke (NCT NCT01183533)

NCT ID: NCT01183533

Last Updated: 2014-11-25

Results Overview

The primary outcome of this study is the frequency of symptomatic hemorrhagic transformation evident within 24 hours of treatment with IV t-PA. Symptomatic was defined as significant clinical deterioration with at least a 4 point or more increase in the NIH Stroke scale.

Off Label Rt-PA
Off label rt-PA used on all subjects enrolled within 3 hours of waking with stroke symptoms at the standard of care dose. Alteplase (iv t-PA): 0.9 mg/kg (maximum of 90 mg) IV t-PA will be administered with 10% bolus given over 1 minute, the rest given as an infusion over the remaining hour.

0 cases.

SECONDARY outcome

Timeframe: 90 days

Population: \^ Note: 2 patients were not available for 90-day follow-up assessments.

Number of patients with mRS of 0 or 1 at 90 days. The mRS is a clinician-reported measure of global disability that has been widely applied for evaluating recovery from stroke. It has a minimum of 0 and a maximum of 6. Zero represents a patient that has no disability or residual stroke symptoms. A score of 1 is defined as: no significant disability: despite symptoms, able to carry out all usual duties and activities. The maximum score, 6, indicates death. A score of 2 is defined as slight disability: unable to perform all previous activities but able to look after own affairs without assistance; a score of 3 is defined as moderate disability: requiring some help but able to walk without assistance; a score of 4 is moderately severe disability: unable to walk without assistance and unable to attend to own bodily needs without assistance; a score of 5 is severe disability: bedridden, incontinent and requiring constant nursing care and attention.
