E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Objective of NOR-TEST 2 is to compare efficacy and safety of tenecteplase 0.4 mg/kg (single bolus) vs. alteplase 0.9 mg/kg (10% bolus + 90% infusion/60 minutes) a) within 4½ hours after symptom onset; b) within 4½ hours after awakening with stroke symptoms, and c) as bridging therapy within 4½ hours before thrombectomy. Hypothesis: Tenecteplase 0.4 mg/kg has superior efficacy and similar safety profile compared with alteplase 0.9 mg/kg. |

E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
General inclusion criteria • Age 18 years or older admitted to hospital with an acute ischaemic stroke • Ischaemic stroke with clinical symptoms corresponding to a NIHSS score of >5. • All stroke sub-types and vascular distributions are eligible. • A visible arterial occlusion is not required for inclusion. • Treatment <4½ hours after stroke onset or after awakening with symptoms. • Beastfeeding women, if a 24 hours stop of feeding is feasible.
Specific sub-set inclusion criteria • Wake-Up Stroke: FLAIR-DWI mismatch on MRI as judged by the (neuro-) radiologist or neurologist. • Thrombectomy: Occlusion of an intracerebral artery, technically accessible for endovascular embolectomy as defined by local treatment protocols. • Signed informed consent and expected cooperation of the patients must be obtained and documented according to ICH GCP, and national/local regulations. A written or signed informed consent before thrombolytic treatment is not necessary, but must be obtained before entering data into the research data base.

|
E.4 | Principal exclusion criteria |
Patients will be excluded from the study if they meet any of the following criteria: • Large areas of hypodense ischaemic changes on baseline CT; • Patients with systolic blood pressure >185 mm Hg or diastolic blood pressure >110 mm Hg in spite of acute antihypertensive treatment; • Pregnant women (are treated with alteplase); • Women with possible pregnancy (are treated with alteplase) • Beastfeeding women, if a 24 hours stop of feeding is not feasible. • Clinical presentation suggesting subarachnoid haemorrhage even if baseline CT is normal; • Known bleeding diathesis; use of oral anticoagulants with no antidot, INR ≥1,4; heparin <48 hours and increased APTT; low molecular weight heparin(oid) <24 hours; another investigational drug <14 days; • Patients with arterial puncture at a noncompressible site or lumbar puncture <7 days; major surgery or serious trauma <14 days; gastrointestinal or urinary tract hemorrhage <14 days; clinical stroke <2 months; history of intracranial haemorrhage; CNS neurosurgery <2 months; serious head trauma <2 months; pericarditis; sepsis; any serious medical illness likely to interact with treatment; confounding pre-existent neurological or psychiatric disease; unlikely to complete follow-up; • Any condition that, in the opinion of the investigator, puts a patient at risk if treated with thrombolysis.
