Brief Summary
This study is to test a hypothesis that temporary implantation of JRecanTM blood flow recanalisation device within 6.5 hours of symptom onset of acute ischemic stroke due to a major intracranial artery occlusion following IV r-tPA can provide a greater rate of early successful recanalisation than treatment of IV r-tPA alone.

Outcome Measures
Primary Outcomes (1)
Early successful recanalisation (assessed by the imaging core laboratory)
TIMI(thrombolysis in myocardial infarction)2 or 3 recanalisation 1 hour after enrollment blindly assessed by the imaging core laboratory and without any presence of symptomatic intracranial hemorrhage within 24 hours blindly assessed by independent neurologists.
24 hours
Secondary Outcomes (3)
Good neurological outcome( modified Rankin Scale (mRS) score ≤2, or National Institutes of Health Stroke Scale(NIHSS)score improvement of 10 points or more)
90 days
Incidence of device related and procedure-related serious adverse events(SAEs)
30 days
Additional safety end-points (symptomatic intracranial haemorrhage at 24 hours, and Death due to any cause at 90 days)
90 days
Study Arms (2)
IV r-tPA with JRecanTM blood FR device
EXPERIMENTALDual IV r-tPA therapy and adjunctive treatment with JRecanTM blood flow recanalisation device
IV r-tPA
ACTIVE COMPARATORIV infusion of r-tPA
Interventions
JRecanTM blood flow recanalisation device
intravenous recombinant human tissue plasminogen activator
Eligibility Criteria
You may qualify if:
- Age 18 - 75
- Clinical presentations consistent with acute ischemic stroke
- NIHSS ≥ 8 and \< 30 at the time of randomization
- Initiation of the correct IV t-PA dose treatment within 4.5 hours of onset of stroke symptoms (onset time is defined as the last time when the patient was witnessed to be at baseline)
- Complement of catheter angiography within 6.5 hours of onset of stroke symptoms
- Thrombolysis in myocardial Infarction (TIMI) 0-1 flow in the intracranial internal carotid artery, M1 segment of the MCA, basilar artery, or intracranial vertebral artery with contralaterally chronic intracranial vertebral artery occlusion confirmed by catheter angiography
- The acute occlusion lesion is accessible to the JRecanTM blood flow recanalisation device
- Functional independence before this time stroke (Modified Rankin Score ≤ 1)
- Subject or subject's legally authorized representative has signed and dated an Informed Consent Form according to country regulations, ethics committee requirements.
- Subject is willing to conduct protocol-required follow-up visits.
You may not qualify if:
- NIHSS \<8 or ≥30
- Rapid neurological improvement prior to study randomization
- Female who is pregnant or lactating or has a positive pregnancy test at time of admission
- Taking part in another clinical study.
- History of stroke in the past 3 months.
- Current participation in another investigational drug or device treatment study.
- Uncontrolled hypertension defined as systolic blood pressure \> 185 or diastolic blood pressure \> 110 that cannot be controlled except with continuous parenteral antihypertensive medication.
- Known hereditary or acquired hemorrhagic diathesis, coagulation factor deficiency. (Patients without history or suspicion of coagulopathy do not require INR or prothrombin time lab results to be available prior to enrollment.)
- Warfarin therapy with INR greater than 1.7.
- Low molecular Weight Heparins (such as Dalteparin, Enoxaparin, Tinzaparin, Fondaparinux) as DVT prophylaxis or in full dose within the last 24 hours from screening.
- Subject who has received heparin or a direct thrombin inhibitor (e.g. rivaroxaban, Angiomax™, argatroban, Refludan™) within the last 48 hours must have a normal partial thromboplastin time (PTT) to be eligible.
- Subject who has received factor Xa inhibitor therapy (e.g. dabigatran) within the past 24 hours must have a normal ecarin clotting time to be eligible. Subject who has received factor Xa inhibitor therapy more than 24 hours ago but less than 48 hours ago must have a normal partial thromboplastin time (PTT) to be eligible.
- Baseline lab values: glucose \< 50 mg/dl or \> 400 mg/dl, platelets \< 100,000, or Hct \< 25.
- Renal Failure as defined by a serum creatinine \> 2.0 or Glomerular Filtration Rate \[GFR\] \< 30.
- Subject who requires hemodialysis or peritoneal dialysis, or who have a contraindication to an angiogram for whatever reason.
