Brief Summary

The purpose of this study was to evaluate the effectiveness of early administration of BXOS110 for injection in reducing overall disability in patients with acute ischaemic stroke.

Detailed Description

This trial was conducted in a multicentre, randomised, double-blind, placebo-parallel controlled design, with a total of three groups of 100 subjects in each of the three planned groups, namely, the BXOS110 high-dose group (3.0 mg/kg, with a maximum dose of up to 300 mg), the BXOS110 low-dose group (2.0 mg/kg, with a maximum dose of up to 200 mg) and the placebo-control group, with the aim of exploring the efficacy and safety of BXOS110 at different doses of BXOS110. efficacy and safety of BXOS110.

The trial was divided into a screening/baseline period, a treatment period and a follow-up period. In the screening/baseline phase, patients signed an informed consent form within 3 hours of stroke onset to enter the trial, and after completing the screening and procedures related to the trial, subjects who met the enrolment requirements were randomly assigned to the BXOS110 high-dose group, the BXOS110 low-dose group, or a placebo-controlled group in a ratio of 1: 1: 1. During the treatment phase, subjects were randomly grouped into groups to start the intravenous treatment, and evaluations were carried out immediately after the administration of BXOS110. immediately after administration; during the Follow-up Period, subjects were evaluated for effectiveness and safety on Day 2, Day 3, Day 10, or at discharge (whichever occurred earlier), Day 30, and Day 90 after administration.

  8. Have a epilepsy history or have epilepsy symptoms after current stoke onset;
  9. Combined with other mental illnesses, resulting in inability or unwillingness to cooperate;
  10. Combined with claudication, osteoarthropathy, etc., resulting in limb movement dysfunction, which is determined by investigators to affect neurological function test;
  11. History of severe head trauma or stroke within 3 months before screening;
  12. History of severe food or drug allergy, or known allergy to the investigational drug and its excipients;

Primary Outcome Measures
NameTimeMethod
Proportion of subjects with mRS score 0-2 on day 90Day 90

Modified Rankin scale The Rankin scale was devised in 1957 for assessment of stroke outcomes, and was modified in 1988 to improve its comprehensiveness.The modified version, or mRS, has since been commonly used to assess disability after a stroke.

The mRS attempts to measure functional independence, incorporating the WHO components of body function, activity, and participation. The scale is defined categorically with seven different grades: 0 indicates no symptoms, 5 indicates severe disability, and 6 indicates death.

A 1-point shift on this scale is often deemed clinically significant because of the large category sizes. Patients may use adaptive devices and still be considered independent, but the need for supervision or even minimum aid from another person is scored as dependent.

Secondary Outcome Measures
NameTimeMethod
Proportion of subjects with NIHSS scores ≤1 on day 10 (or at discharge)Day 10

The NIHSS is a 15-item impairment scale, which provides a quantitative measure of key components of a standard neurological examination.

The scale assesses level of consciousness, extraocular movements, visual fields, facial muscle function, extremity strength, sensory function, coordination (ataxia), language (aphasia), speech (dysarthria), and hemi-inattention (neglect).

Proportion of subjects with mRS score 0-1 on day 90Day 90

Proportion of subjects with Barthel Index Scale (BI) scores ≥95 on day 90Day 90

The BI is a scale that measures ten basic aspects of activity related to self-care and mobility. The normal score is 100, and lower scores indicate greater dependency.

Proportion of subjects with a ≥4-point reduction in NIHSS score from baseline at day 10 (or at discharge)D10

The NIHSS is a 15-item impairment scale, which provides a quantitative measure of key components of a standard neurological examination.

The scale assesses level of consciousness, extraocular movements, visual fields, facial muscle function, extremity strength, sensory function, coordination (ataxia), language (aphasia), speech (dysarthria), and hemi-inattention (neglect).

Day 90 European Five Dimensional Health Scale (EQ-5D) ScoreDay 90

The EQ-5D is a generic HRQoL measurement with evidence of good reliability and validity in various disease populations, including stroke. The EQ-5D contains the self- reported health state profile of five dimensions (mobility, self-care, usual activity, pain/discomfort, and depression/ anxiety) and a visual analog scale (EQ-VAS) .

Change in infarct volume from baseline after 24 hours of dosing24 hours after treatment

Change in infarct volume from baseline after 24 hours of dosing

Proportion of subjects with ≥4 point increase in NIHSS score during hospitalisationD1~ Day 10

The NIHSS is a 15-item impairment scale, which provides a quantitative measure of key components of a standard neurological examination.

The scale assesses level of consciousness, extraocular movements, visual fields, facial muscle function, extremity strength, sensory function, coordination (ataxia), language (aphasia), speech (dysarthria), and hemi-inattention (neglect).
