Title: Multicentre, Multinational, Double-Blind, Placebo-Controlled, Randomised Phase II Trial of Desmoteplase (INN) in the Indication of Acute Ischaemic Stroke
Brief Summary: The DIAS study (Part 2) was performed to support the dose finding of desmoteplase treatment in subjects with acute ischemic stroke selected by perfusion/diffusion mismatch on MRI within a time window of 3 to 9 h after stroke-symptom onset. In addition, it assessed safety and tolerability of 3 doses of desmoteplase compared with placebo with special consideration of intracranial hemorrhage and major systemic bleedings.


Options:
A: Inclusion Criteria:

* Female or male inpatients
* Age: 18 - 80 years.
* Clinical diagnosis of ischemic stroke causing a measurable neurological deficit defined as impairment of language, motor function, cognition and/or gaze, vision or neglect. Ischemic stroke is defined as an event characterized by the sudden onset of an acute focal neurologic deficit presumed to be due to cerebral ischemia after CT scan excludes hemorrhage.
* Onset of symptoms between 3 and 4 hours prior to initiation of administration of study drug.
* Stroke symptoms are to be present for at least 30 minutes and have not significantly improved before treatment. Symptoms must be distinguishable from an episode of generalized ischemia (i.e. syncope), seizure, or migraine disorder.
* Patient is willing to participate voluntarily and to sign a written patient informed consent. Informed consent will be obtained from each patient or the subject's legally authorized representative or relatives, or deferred where applicable, according to the regulatory and legal requirements of the participating country.
* Patients who are unable to sign but who are able to understand the meaning of participation in the study may give an oral witnessed informed consent. These patients have to make clear undoubtfully that they are willing to participate voluntarily and must be able to understand an explanation of the contents of he information sheet.
* Willingness and ability to comply with the protocol.

Exclusion Criteria:

* Evidence of intracranial hemorrhage (ICH) on the CT-scan.
* Symptoms of ischaemic attack began more than 4 hours and 30 minutes prior to infusion start or when time of symptom onset is unknown.
* Minor neurological deficit or symptoms rapidly improving before start of infusion.
* Severe stroke as assessed clinically (e.g. NIHSS\>25) and/or by appropriate imaging techniques.
* Epileptic seizure at onset of stroke
* Symptoms suggestive of subarachnoid haemorrhage, even if the CT-scan is normal.
* Administration of heparin within the previous 48 hours and a thromboplastin time exceeding the upper limit of normal for laboratory
* History of prior stroke and concomitant diabetes. \* Prior stroke within the last 3 months
* Platelet below 100,000/mm3. \* Systolic blood pressure \>185 mmHg or diastolic blood pressure \>110 mmHg, or aggressive management (IV medication) necessary to reduce BP to these limits.
* Blood glucose \<50 or \> 400 mg/dl (\< 2.77 or \> 22.15 mmol / l). \* Known haemorraghic diathesis
* Patients receiving oral anticoagulants. \* Manifest or recent severe or dangerous bleeding
* Known history of or suspected intracranial haemorrhage
* Suspected subarachnoid haemorrhage or condition after subarachnoid haemorrhage from aneurysm
* History of central nervous system damage (i.e. neoplasm, aneurysm, intracranial or spinal surgery)
* Haemorrhagic retinopathy,e.g. in diabetes (vision disturbances may indicate haemorrhagic retinopathy)
* Recent (less than 10 days) traumatic external heart massage, obstetrical delivery, recent puncture of a non-compressible blood-vessel (e.g. subclavian or jugular vein puncture.
* bacterial endocarditis, pericarditis.\* Acute pancreatitis
* Documented ulcerative gastrointestinal disease during the last 3 months, oesophageal varices, arterial- aneurysm, arterial/venous malformation
* Neoplasm with increased bleeding risk
B: Inclusion Criteria:

* Eligible for study treatment within 3-9 hours after onset of stroke symptoms.
* Score of 4-24 on the NIHSS with clinical signs of hemispheric infarction (i.e. hemiparesis) suggestive of ischemic stroke.

Inclusion Criteria from diagnostic imaging screening:

* Distinct penumbra (at least 20%), measured by MRI (PWI/DWI) or perfusion CT, related to middle cerebral artery (MCA), anterior cerebral artery (ACA), or posterior cerebral artery (PCA) territory in a hemispheric distribution.

Exclusion Criteria:

* History or clinical presentation of intracranial hemorrhage (ICH), subarachnoid hemorrhage, arteriovenous malformation, aneurysm, or cerebral neoplasm.
* Rapidly improving neurological symptoms.
* Pre-stroke MRS score of \> 1 (including previous disability).
* Suspected acute vertebral or basilar artery occlusion.
* Current use of anticoagulants and a prolonged prothrombin time.
* Uncontrolled hypertension.
* Baseline hematocrit of \< 0.25.
* Baseline platelet count \< 100,000/mm3.
C: Inclusion Criteria:

* scoring 4 to 20 on the National Institute of Health Stroke Scale (NIHSS)
* showing a perfusion-diffusion mismatch on MRI of 20 %
* enrolment within a 3 h to 9 h time window after symptom onset.
* 18-85 years of age

Exclusion Criteria:

* Participation in any interventional trial in the previous 30 days.
* Women in the childbearing age.
* Any history of intracranial hemorrhage, subarachnoid hemorrhage, neoplasm, arteriovenous malformation or aneurysm.
* Conditions that, according to the judgment of the investigator, might impose an additional risk to any individual stroke patient when receiving study medication (this applied to patients on platelet-function inhibitors as well).
* MRI exclusion criteria: Evidence of ICH, Evidence of SAH, Signs of extensive early infarction on DWI assessed by evidence of involvement of \>1/3 of the middle cerebral artery (MCA) territory. No perfusion deficit, Internal carotid artery (ICA) occlusion ipsilateral to stroke lesion without additional ipsilateral MCA, anterior cerebral artery (ACA) or posterior cerebral artery (PCA) occlusion. Any intracranial pathology that would interfere with the MRI assessment of acute ischemic stroke.
