Clinical Trial Summary

To evaluate the safety profiles of HTU-PA in patients with acute ischemic stroke.

Description:

Cerebrovascular disease, the third leading cause of death after heart disease and cancer in developed countries, has an overall prevalence of 794 per 100,000. In the United States, it is estimated that more than 400,000 patients are discharged each year from hospitals after a stroke. The loss of these patients from the work force and the extended hospitalization they require during recovery make serious economic impact. In Taiwan, Cerebrovascular disease is the second cause of death.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 30
• Est. completion date: June 2004
• Accepts healthy volunteers: No
• Gender: Both
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Subjects with cerebral ischemia at any location producing a serious measurable deficit by NIHSS scale and who received study medication within 5 hours after the onset of the symptom. A serious measurable deficit by NIHSS was defined as the NIHSS ? 9 and ? 20 (for brain stem stroke, patients with NIHSS > 20 were included).

• Subjects were ? 18 years old, of either sex.

• Subjects or his/her legal guardians demonstrated their willingness to participate in the study and comply with its procedures by signing a written informed consent.

• Subjects with Modified Rankin Scale > 1.

Exclusion Criteria:

• Onset of symptoms on awaking from sleep.

• Intracranial bleeding detected on a pretreatment head computerized tomographic (CT) scan.

• Clinical presentation suggested a subarachnoid hemorrhage even if the head CT scan was normal.

• Head CT showed the evidence of early infarct sign > 1/3 of MCA territory.

• Subjects had generalized seizure at the onset of the stroke.

• Subjects with blood glucose < 50 mg/dl or > 400 mg/dl.

• Subjects had another stroke, head trauma, cerebral hemorrhage or ischemic infarction within 3 months prior to the study entry.

• Subjects with a significant surgery within 14 days prior to study entry.

• Subjects with a history of gastrointestinal or urinary tract hemorrhage within 21 days prior to the study entry.

• Subjects with lumbar puncture or arterial puncture of non-compressible site within 14 days prior to the study entry.

• Subjects had known bleeding diathesis.

• Subjects with other serious medical illness that interfered with the study.

• Subjects had a platelet count < 100,000/mm3; hematocrit < 30%.

• Subjects with other serious medical illness that interfered with the study.

• Subjects had aPTT or PT > upper normal limit.

• Subjects had uncontrolled hypertension (> 180 mmHg systolic or > 110 mmHg diastolic) without additional anti-hypertensive medication at screening visit.

• Subjects with recent transmural myocardial infarction and evidence of pericarditis within 3 weeks prior to the enrollment.

• Subjects had intracranial neoplasm, arteriovenous malformation, or aneurysm.

• Subjects had hemostasis defects including secondary to severe hepatic or renal disease.

• Subjects with history of drug or alcohol abuse within 1 year prior to the study entry.

• Subjects had significant hepatic dysfunction (SGOT/SGPT ? 3 x upper normal limit).

• Subjects had serum creatinine level ? 2 x upper normal limit or on renal dialysis.

• Subjects had administration of any other investigational drug within 30 days prior to study entry.

• Woman who was pregnant or nursing.

• Subjects had used other thrombolytics (streptokinase, tissue plasminogen activator, urokinase, anisoylated plasminogen streptokinase activator complex, anticoagulants).

• Subjects had severe cardiac disease (New York Heart Association Functional Classification III and IV).

• Subjects had history of cancer except inactive non-melanoma skin cancer, in situ carcinoma of the cervix, or any cancer in patient’s disease free for more than 5 years.

• Subjects had any clinically significant deviation from normal in the physical examination that, in the investigator judgment, interfered with the study evaluation or affect subject safety.

• Subjects with history of lupus.

• Vasculitis was the cause of ischemic stroke.

• Subjects had been enrolled in this study previously.
