A.R.I.S.E. is a post approval observational study using standard care. The purpose of this study is to collect information about the ability of the EmboTrap device to remove blood clots from the brain, and the associated performance characteristics and clinical outcomes. No formal hypothesis testing is needed as no comparisons are planned within the study. Instead, estimates of each population parameter of interest for all primary and secondary endpoints will be provided using appropriate confidence intervals.

Condition Intervention
Ischemic Stroke
Device: EmboTrap® Revascularization Device

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A.R.I.S.E. Analysis of Revascularisation in Ischemic Stroke With EmboTrap: Post Marketing Observational Study of CE Marked EmboTrap Mechanical Thrombectomy Device

Further study details as provided by Neuravi Limited:

Primary Outcome Measures:
  • Revascularisation as measured by modified Thrombolysis in Cerebrovascular Infarction (mTICI with 2c) score of at least 2b following the use of the Neuravi device. [ Time Frame: Day 1 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to Revascularization [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Defined as time from groin puncture to visualization of final angiographic result.

  • Mortality post procedure [ Time Frame: 7 and 90(±14) days post procedure ] [ Designated as safety issue: No ]
    All procedure related mortality (i.e. directly traceable to a procedure related SAE).

  • Serious Adverse Device related effects (SADE) [ Time Frame: 24(-8/+12) hours Post Procedure ] [ Designated as safety issue: No ]
    SADE is defined as vessel perforation or vessel dissection, which is attributable to the Neuravi device, or where the Neuravi device cannot be ruled out as the cause.

  • Symptomatic ICH [ Time Frame: 24(-8/+12) hours Post Procedure ] [ Designated as safety issue: No ]
    Symptomatic ICH rate within 24 hours (range: 16 to 36 hours) post-procedure. Symptomatic intracranial haemorrhage (parenchymatous haemorrhage type 2), at post-treatment scan combined with neurological deterioration (C2) leading to an increase of 4 points or more on the NIH Stroke Scale.

  • Clinical outcome at 90 days [ Time Frame: 90(±14) days Post Procedure ] [ Designated as safety issue: No ]
    A good clinical outcome will be judged to be a mRS score of ≤2 at 90(±14) days.

  • Rate of New Territory Embolization [ Time Frame: 24(-8/+12) hours Post Procedure ] [ Designated as safety issue: No ]
    Embolization, or thrombus dislocation, into a previously uninvolved vascular territory as evaluated from angiographic images by the Angiography Core Lab and the Data Safety Monitoring Board.

  • Evidence of Infarction [ Time Frame: 24(-8/+12) hours Post Procedure ] [ Designated as safety issue: No ]
    Infarction, of a previously uninvolved vascular territory, as evaluated from 24hr Computed Tomography imaging by the Angiography Core lab.

Study Population

Ischemic stroke patients


Inclusion Criteria:

  • The patient or the patient's legally authorized representative has signed and dated an Informed Consent Form.
  • Aged between 18 years and 80 years (inclusive).
  • A new focal disabling neurologic deficit consistent with acute cerebral ischemia.
  • NIHSS score ≥8 and ≤25.
  • Pre-ictal mRS score of 0 or 1.
  • Angiographic confirmation of an occlusion of an ICA (including T and L occlusions), M1 or M2, MCA, or BA with TICI flow of 0-1.
  • Confirmation by the interventionalist, after screening CT or MRI, that the treatment site can be accessed with the Neuravi device.
  • The interventionalist estimates that at least one deployment of the Neuravi device can be completed within 5 hours from the onset of symptoms, or if time of onset of symptoms is unknown or > 5 hours, patients can be included using imaging with the following criteria:

    1. MRI criterion: ASPECTS 8 to 10, or,volume of diffusion restriction ≤30 mL and mismatch between perfusion reduction and diffusion restriction present.
    2. CT criterion: ASPECTS 8 to 10 on baseline CT or CTA-source images, or, volume of significantly lowered CBV ≤30 mL and mismatch between perfusion reduction and low CBV present.

Exclusion Criteria:

  • Life expectancy of less than 6 months.
  • Females who are pregnant or lactating.
  • History of severe allergy to contrast medium.
  • Has suffered a stroke in the past three months.
  • The patient presents with an NIHSS score <8 or >25 or is physician assessed as being in a clinically relevant uninterrupted coma.
  • Use of warfarin anticoagulation with International Normalized Ratio (INR) > 3.0.
  • Platelet count < 50,000.
  • Glucose < 50 mg/dL.
  • Heparin use in previous 24 hours with PTT or ACT > 2X normal.
  • Any known hemorrhagic or coagulation deficiency.
  • Computed tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage on presentation.
  • For basilar artery occlusion, extended early ischemic changes as confirmed by pc-ASPECTS ≤ 7 on baseline CT or CTA-source images, or extensive DWI lesions in the midbrain or pons regions on pre-treatment MRI.
  • Baseline CT or MRI showing mass effect or intracranial tumor (except small meningioma).
  • Excessive arterial tortuosity that precludes the study device from reaching the target vessel.
  • A proximal stenosis or complete occlusion that cannot, as judged by the responsible interventionalist, be treated safely or which prevents access to the occluded vessel with the Neuravi device.
  • Evidence of active infection.
  • Known cancer with metastases
  • Current use of cocaine or other vasoactive substance.
