MRI-guided thrOmbolysis for Stroke bEyond Time Window by TNK (ROSE-TNK): a Prospective, Randomized, Blinded Assessment of Outcome and Open Label Multi-center Study

This is an open label multicentre trial, evaluating the utility of MRI-guided thrombolysis for stroke beyond time window by Tenecteplase (TNK-tPA). This exploratory study was to describe the feasibility and outcome of thrombolytic therapy with TNK-tPA in 4.5-24 hours after stroke guided by a mismatch between diffusion-weighted imaging and FLAIR in the region of ischemia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In patients with acute stroke with an unknown time of onset, intravenous alteplase guided by a mismatch between diffusion-weighted imaging and FLAIR in the region of ischemia resulted in a significantly better functional outcome at 90 days. This trial will enroll acute ischemic stroke patients within 4.5 to 24 hours of onset. All the patients had an ischemic lesion that was visible on MRI diffusion-weighted imaging but no parenchymal hyperintensity on fluid-attenuated inversion recovery (FLAIR), which indicated that the stroke had a ischemic penumbra. Randomization will be 1:1 to TNK-tPA (experimental) or standard treatment (control), in compliance with guidelines for acute stroke. Clinical outcome was assessed by disability on the basis of the modified Rankin scale at 90 days follow-up, which will be performed by a blinded assessor.
