Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Inclusion Criteria:

  1. Age is 18 years old or above.

  3. Randomized within 24h after the onset.
  4. The NIHSS score is above 5 and the ASPECT score is above 3 points while receiving imaging examination;
  5. The mTICI score after endovascular treatment (EVT) is above 2b.
  6. informed consent.

Exclusion Criteria:

  1. Intracranial hemorrhage confirmed by CT or MRI.
  2. mRS score>2 for patients <80 years, or mRS score>1 for those ≥80 years before onset.

  9. Hemoglobin value <8g/L.
  10. Recent history of using other JAK inhibitors or potent immunosuppressants, including but not limited to the combined use with potent immunosuppressive drugs such as azathioprine, tacrolimus, tofacitinib and fedratinib, etc. Tortuous arteries make the thrombectomy device unable to reach the target blood vessel.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Distribution of 90-day mRS scores
Time Frame: 90±14 days post-procedure
The Modified Rankin Scale (mRS) measures degree of disability/dependence after a stroke, with a score of 0 indicating no disability, 1 no clinically significant disability, 2 slight disability, 3 moderate disability but remaining able to walk unassisted, 4 moderately severe disability, 5 severe disability, and 6 death.
90±14 days post-procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
