DESMOTEPLASE (INN) IN ACUTE ISCHAEMIC STROKE: PHASE III; A prospective, randomised, double-blind, placebo-controlled, single bolus, multinational, multi-centre, parallel group, dose ranging study of desmoteplase (INN) in the indication of acute stroke - DIAS-2

Recruitment & Eligibility

Status: ot Recruiting

Sex: All

Target Recruitment: 186

Inclusion Criteria

1.Informed Consent (all sites) and HIPAA authorization (US sites only)
2.Age 18 – 85 years
3.Treatment onset within 3 - 9 hours after onset of stroke symptomsIf the exact onset of stroke is unclear, but the onset of stroke symptoms was less than 8 hours before arrival at the hospital, then the patient can be considered eligible for the study (this provides 1 hour for eligibility determination prior to receipt of randomized therapy).
4.Score of 4 - 20 on the NIHSS with clinical signs of hemispheric infarction (e.g. hemiparesis) suggestive of ischemic stroke

5.Inclusion Criterion from diagnostic imaging screening:A 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
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1.Previous participation in a desmoteplase study (i.e., DEEP, DIAS, DEDAS, DEPTH)
2.Participation in any investigational study in the previous 30 days
3.Any terminal illness that is serious or advanced (patient is not expected to survive more than 1 year)
4.Any condition that could impose hazards to the patient if study therapy is initiated or affect the participation of the patient in the study (this applies to patients with severe microangiopathy such as hemolytic uremic syndrome or thrombotic thrombocytopenic purpura)The judgment is left to the discretion of the Investigator.
5.Patients not able to receive study medication within 45 minutes after completion of diagnostic imaging screening
6.Pregnant women (positive serum ßHCG pregnancy test, positive urine pregnancy test or clinically evident pregnancy)
7.Rapidly improving neurological symptoms especially if the rate of improvement is projected to give the patient an NIHSS score of < 4 at randomization
8.Pre-stroke MRS score of > 1 (indicating previous disability)
9.History or clinical presentation of ICH, subarachnoid hemorrhage (SAH), arterio-venous (AV) malformation, aneurysm, or cerebral neoplasm
10.Suspected acute vertebral or basilar artery occlusion
11.Current use of oral anticoagulants and a prolonged prothrombin time (INR > 1.6)
12.Use of heparin, except for low dose subcutaneous heparin, in the previous 48 hours and a prolonged partial thromboplastin time exceeding the upper limit of the local laboratory normal range
13.Use of glycoprotein IIb - IIIa inhibitors within the past 72 hours. Use of single agent oral platelet inhibitors (clopidogrel or low-dose aspirin) prior to study entry is permitted.
14.Baseline platelet count < 100,000/mm³
15.Baseline hematocrit of < 0.25
16.Baseline blood glucose < 50 mg/dl or > 200 mg/dl (< 3 mmol/l or > 11 mmol/l)Patients with initially elevated blood glucose levels can be considered for the study if the levels decrease spontaneously below the upper limit until time of randomization. Patients on chronic diabetes treatment whose blood glucose levels decrease below 200 mg/dl (11 mmol/L) with continuation of their normal regimen can also be considered for the study. No treatment for the elevated glucose levels is permitted, except for known diabetics currently under treatment for glucose control who had not taken their medication for that day.
17.Uncontrolled hypertension defined by a blood pressure > 185 mmHg systolic or >110 mmHg diastolic on at least 2 separate occasions at least 10 minutes apart, or requiring aggressive treatment to reduce the blood pressure within the limitsThe definition of aggressive treatment” is left to the discretion of the responsible Investigator.
18.Hereditary or acquired hemorrhagic diathesis
19.Gastrointestinal or urinary bleeding within the preceding 21 days
20.Arterial puncture at a non-compressible site within the previous 7 days
21.Another stroke or a serious head injury in the previous 6 weeks
22.Any history of prior stroke in a patient with diabetes unless the blood glucose is within the range indicated above.
23.Major surgery within the preceding 14 days
24.Seizure at the onset of stroke
25.Acute myocardial infarction (AMI) within the previous 3 weeks
26.Exposure to a thrombolytic within the previous 72 hours
27.Any intracranial pathology that would interfere with the assessment of the chosen imaging technique for screeningExclusion criteria from diagnostic imaging screeni
