Summary
Brief summary
Stroke is a leading causes of death and disability. At least 20% of strokes occur during
sleep, so- called 'wake up stroke'. Thrombolysis with the clot-busting drug alteplase is
effective for acute ischaemic stroke, provided that it is given within 4.5 hours of symptom
onset. Patients with wake-up stroke are currently ineligible for clot-busting therapy.
Previous studies indicate that many wake-up strokes occur just before awakening.

In this study, patients with wake-up stroke will be randomized to thrombolysis with
tenecteplase and best standard treatment or to best standard treatment without thrombolysis.
Tenecteplase has several potential advantages over alteplase, including very rapid action and
that it can be given as a single injection. Prior to thrombolysis, a brain scan must be done
to exclude bleeding or significant brain damage as a result from the stroke. We will use a CT
scan to inform this decision. CT is used as a routine examination in all stroke patients.
Other studies testing clot-busting treatment in wake-up stroke are using alteplase and more
complex brain scans, which are not routinely available in the emergency situation in all
hospitals.
