December 18, 2020 updated by: Yongjun Wang, Beijing Tiantan Hospital

Phase II Dose-finding Open Study of Recombinant Human TNK Tissue-type Plasminogen Activator (rhTNK-tPA) Injection Administered Within 3 Hours After Onset of Hyperacute Ischemic Stroke

To explore the safe and efficacious dose of rhTNK-tPA injection administered within 3 hours after onset of hyperacute ischemic stroke; to provide dose evidence for phase III clinical trial.

Intervention / Treatment

Detailed Description

To evaluate the safety and efficacy of rhTNK-tPA at different doses of 0.10 mg/kg, 0.25 mg/kg and 0.32 mg/kg compared with standard rt-PA intravenous thrombolytic therapy within 3 hours after onset of ischemic stroke. The primary objective of this study is to evaluate the differences of NIHSS scores among the four treatment groups at 14 days after intravenous thrombolysis.

Description

Inclusion Criteria:

  1. Age over 18 years.
  2. Time from onset to treatment < 3 hours; the time symptoms start is defined as "the last moment they appear normal".
  3. Diagnosis of ischemic stroke according to "2014 China Guideline for Diagnosis and Treatment of Acute Ischemic Stroke" with assessable neurological impairment e.g., language, motor function, cognitive impairment, gaze impairment, visual field deficit and/or visual neglect. Ischemic stroke is defined as sudden acute focal neurological impairment with suspected cerebral ischemia, hemorrhage ruled out by CT scan.
  4. mRS > 2 at the first onset or prior onset.
  5. Baseline NIHSS score is > 4 and < 26.
  6. Signed informed consent.

Exclusion Criteria:

  1. Absolute contraindications:

    1.1 History of severe head trauma or stroke within 3 months; 1.2 Suspected subarachnoid hemorrhage; 1.3 Arterial puncture at a non-compressible site within the previous 1week; 1.4 History of intracranial hemorrhage; 1.5 Intracranial tumor, vascular malformation, or arterial aneurysm; 1.6 Recent intracranial or intraspinal surgery; 1.7 Systolic blood pressure ≧ 180 mm Hg, or diastolic blood pressure ≧ 100 mm Hg; Increased blood pressure; 1.8 Active internal bleeding ; 1.9 Acute bleeding tendency, including platelet count below 100×109/L or otherwise; 1.10 Heparin treatment was performed within 48 h ( APTT exceeded the upper limit of normal range ) ; 1.11 Warfarin has been taken orally , and the international standardized ratio is INR > 1.7 or PT > 15 s ; 1.12 Anticoagulant drugs such as thrombin inhibitor or Xa factor inhibitor , argatroban ( including new anticoagulants with unclear mechanism ) are currently being used , and various sensitive laboratory tests are abnormal ( such as live ) APTT , INR , Platelet count , Serpentine ECT of pulse enzyme setting time ; thrombin time TT or appropriate determination of Xa factor activity ) ; 1.13 Blood glucose < 2.7 mmol/L; 1.14 CT showed multilobular infarction ( low density > 1 / 3 cerebral hemisphere )

  2. Relative contraindications : The risks and benefits of thrombolysis should be carefully considered and weighed in the following cases ( that is , although there is one or more relative contraindications , it is not absolutely impossible to thrombolysis ).
