Clinical Trial Summary

Overall Design: a multicenter, randomized, double-blind, placebo-controlled, parallel-group, dose-exploration study. Main outcome: 1.To evaluate the efficacy and safety of XY03-EA tablets in the treatment of acute ischemic stroke.

Description:

The population is patient who with acute ischemic stroke within 48 hours of onset (including RT-PA intravenous thrombolytic therapy) . The patients were randomized based on being received rt-PA Intravenous thrombolysis or not. Patients who met the inclusion criteria for the protocol were stratified randomly and assigned in a 1:1:1 ratio to three groups: the XY03-EA 300mg, 600mg two-dose group, and the placebo group. The study was divided into 3 stages: screening stage, treatment stage and follow-up stage. The sample size was 420 patients. Main outcome: 1.To evaluate the efficacy and safety of XY03-EA tablets in the treatment of acute ischemic stroke. Secondary outcome: 1. Explore the dose-response relationship of XY03-EA tablets in the treatment of acute ischemic stroke, and provide data support for later clinical study; 2. Explore PK characteristics of XY03-EA and its metabolites in patients with acute ischemic stroke based on population PK analysis method.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The proportion of patients with Modified Rankin Scale (mRS) score = 1 point at 90 days after administration.	The proportion of patients with Modified Rankin Scale (mRS) score = 1 point at 90 days after administration.; Modified Rankin Scale, a commonly used scale for measuring the degree of dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. 0 - No symptoms.1 - No significant disability. Able to carry out all usual activities, despite some symptoms.2 - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.3 - Moderate disability. Requires some help, but able to walk unassisted.4 - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.5 - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.6 - Dead. The mRS scores between 3 to 6 points are considered to be poor functional outcome.	90 days
Secondary	The proportion of patients with Modified Rankin Scale (mRS) score = 2 point at 14(discharge) , 30,60,90 days after administration.	The proportion of patients with Modified Rankin Scale (mRS) score = 2 point at 14(discharge) , 30,60,90 days after administration;	14(discharge) , 30,60,90 days
Secondary	The proportion of patients with Modified Rankin Scale (mRS) score = 1 point at the 30,60,days after administration;	The proportion of patients with Modified Rankin Scale (mRS) score = 1 point at the 30,60,days after administration;	30 and 60 days
Secondary	The change of NIHSS score from baseline at 14(discharge) , 30,60,90 days after administration;	The change of NIHSS score from baseline at 14(discharge) , 30,60,90 days after administration; The NIHSS is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.	14(discharge) , 30,60,90 days
Secondary	The proportion of patients with NIHSS score =1 or decrease =4 at 30,60, and 90 days after administration;	the proportion of patients with NIHSS score =1 or decrease =4 at 30,60, and 90 days after administration;	30,60, and 90days
Secondary	The proportion of patients with a BI =95 points at 90 days after administration;	The proportion of patients with a BI =95 points at 90 days after administration;The BI Scale is a 10-item scale that assesses the ability of daily living. Each item is given 15,10,5 or 0 points depending on whether or not the patient needs help and the degree of help and the time . The total score is 0 to 100 points, the higher the score, the better the independence and self-rationality. According to the assessment results, the ability of daily activities was divided into 3 grades: good, moderate and poor, with a score of more than 60 being good, and basic daily life being self-care; less than or equal to 40 points for poor, most of daily life relying on family care.	90 days
Secondary	The change in MMSE score compared with baseline at 90 days after administration;	The change in MMSE score compared with baseline at 90 days after administration; Mini-mental state examination (MMSE) can comprehensively, accurately and rapidly reflect the intelligence status and the degree of cognitive impairment of the subjects. The scale includes the following 7 aspects: time orientation, place orientation, immediate memory, attention and numeracy, delayed memory, language, visuospatial. The total score of the scale ranged from 0 to 30. The test scores are closely related to the educational level.	90 days
Secondary	New vascular events The proportion of patients with new vascular events	The proportion of patients with new vascular events (ischemic stroke/hemorrhagic stroke/TIA/myocardial infarction/vascular death) within 90 days after administration.	90 days
