Drug Information available for: Alteplase

Arm Intervention/treatment
Experimental: Group A
Recombinant human urokinase (rhPro-UK)
Drug: Recombinant human urokinase
Patients receive rhPro-UK 35mg,15mg of which is given as a bolus within 3 minutes followed by dlivery of the remaining 20 mg as a constant infusion over a period of 30 minutes.
Other Name: rhPro-UK

Active Comparator: Group B
Drug: Alteplase
Patients receive rt-PA in a dose of 0.9mg per kilogram of body weight(maximum,90 mg),10 percent of which was given as a blous followed by delivery of the remaining 90 percent as a constant infusion over a period of 60 minutes.
Other Name: rt-PA

Primary Outcome Measures :
  1. Functional handicap [ Time Frame: 90days ]
    Proportion of patients achieving a Modified Rankin Scale(mRS,which has a range of 0 to 6, with 0 indicating no symptoms at all and 6 indicating death) of 0 to 1 at 90 days after treatment.

Secondary Outcome Measures :
  1. Proportion of Neurological Improvement [ Time Frame: 90 days ]
    Proportion of patients achieving a NIHSS(national institutes of health stroke scale) ≦1 or reduction of ≥4 NIHSS points at 24 hours after treatment.

  2. Scores of Neurological Improvement [ Time Frame: 24 hours ]
    NIHSS changes from baseline at 24 hours after treatment

  3. Long-term Change from Baseline [ Time Frame: 90 days ]
    NIHSS, mRS and Barthel Index(which assesses the ability to perform activities of daily living, on a scale that ranges from 0 to 100) changes from baseline on 90 days after treatment.

  4. Proportion of Long-term Improvement [ Time Frame: 90 days ]
    Proportion of patients achieving a mRS of 0 to 2 and a Barthel Index of 75 to 100 at 90 days after treatment.

  5. Systemic hemorrhage [ Time Frame: 90days ]
    Severe systemic hemorrhage

  6. Symptomatic intracerebral hemorrhage [ Time Frame: 90days ]
    Symptomatic intracerebral hemorrhage (sICH)

  7. Death [ Time Frame: 7 days and 90 days ]

  8. Recurrence [ Time Frame: 7 days ]
    Recurrence of stroke

  9. Liver function [ Time Frame: 7 days ]
    The incidence of ALT≥3ULN in liver biochemical examination

  10. Renal function [ Time Frame: 7 days ]
    The incidence of Scr rising to 3 times or ≥ 4mg/dl more than the base value
