Ischemic Stroke, Tongxinluo capsule
Brief summary
The purpose of this study is to assess the effects in improving life self-care ability of stroke patients after taking Tongxinluo Capsule(within 72 hours after onset) versus Placebos for 90 days.
Detailed description
The study is a randomized, double-blind, placebo controlled, multi-center trial. We aim to enroll a total of 1968 individuals(984 cases in each group) with acute ischemic stroke less than 72 hours after onset. Participants will be randomized into Tongxinluo capsule treatment group with the capsule administration of 4 granules tid. for 90 days, while the patients in the control group receive placebo capsule. NIH Stroke Score of the subjects is 4-22 at randomization. Evaluations of efficacy and safety will be taken at baseline, 7 days, discharge date and 90 days. Neuroimaging \[magnetic resonance imaging (MRI) scans\] will be obtained at baseline and 90 days after therapy. The primary efficacy endpoint is the proportion of Modified Rankin Scale (mRS) ≤1 at 90 days.

Inclusion criteria
* Ischemic stoke within 72 after onset, confirmed by MRI or CT. * Age 35-75 years, inclusive. * Patients with the first attack or patients with stroke history(modified Rankin Scale score 0-1). * Clear signs of localization of nervous system, NIHSS score 4 to 22. * Patient or proxy has signed informed consent.
Exclusion criteria
* Hemorrhage diseases according to head CT or MRI, such as hemorrhagic stroke, epidural hematoma, intracranial hematoma, intraventricular hemorrhage, subarachnoid hemorrhage, haemorrhage after cerebral infarction. * Transient Ischemic Attack (TIA). * Severe disturbance of consciousness: 1a of NIHSS score\>1 point; Difficulty in swallowing, unable to take oral capsules; any of 5a, 5b, 6a, 6b of NIHSS score\>2 point. * Convinced of stroke caused by brain tumor, brain trauma, hemopathy, etc. * Hemorrhagic tendency patients. * Patients with endovascular treatment after the onset of stroke. * Patients with dementia, severe Parkinson's disease, mental disorders, limb dysfunction caused by other diseases or other conditions that may affect the therapeutic efficacy. * Uncontrolled hypertension (≥200 mmHg systolic or ≥110 mmHg diastolic) or hypotension (≤90 mmHg systolic or ≤60mmHg diastolic); severe hyperglycemia(blood glucose ≥400 mg/dl) or hypoglycemia( blood glucose≤50 mg/dl). * Severe hepatic insufficiency defined as transaminase values \> 2x upper limit of normal; severe renal insufficiency defined as values serum creatinine\> 1.5x upper limit of normal; cardiac dysfunction or other serious systemic disease with life expectancy ≤3 months. * Patients with concurrent malignancy or ongoing anti-tumor therapy. * Patients with history of being allergic to the trial medicine. * Pregnancy, breastfeeding or potential pregnancy. * Within three months or currently participating in another investigational study. * Any other condition that in the opinion of the investigator should preclude study participation.
