Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  5. Pre-stroke modified Rankin Score (mRS) <= 2
  6. Acute occlusion of the M1 segment of the middle cerebral artery (MCA), internal carotid artery (ICA), vertebral or basilar arteries confirmed via computed tomography angiography (CTA) and/or magnetic resonance angiography (MRA)
  7. The Investigator estimates that at least one delivery of the Route 92 Medical Reperfusion System can be completed within 24 hours of time last known well
  8. In the opinion of the Investigator, reperfusion of the ischemic territory will result in clinical benefit

  6. Subject participating in another study involving an investigational device or drug.
  7. Known connective tissue disorder affecting the arteries (e.g. Marfan syndrome, fibromuscular dysplasia, Ehlers-Danlos syndrome)
  8. Any known pre-existing hemorrhagic or coagulation deficiency
  9. Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage
  10. Baseline CT or MRI showing intracranial tumor (except small meningioma)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Thrombectomy
Aspiration of clot with large bore catheter in acute ischemic stroke patients
Device: Thrombectomy
The Route 92 Medical Reperfusion System is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease within the internal carotid, middle cerebral, basilar and vertebral arteries.

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.

Time Frame: Procedure
The primary effectiveness endpoint is arterial revascularization as measured by a modified Thrombolysis in Cerebrovascular Infarction (mTICI) score of 2b or greater at the end of angiography after all endovascular treatments.
Procedure
Device-related peri-procedural complications
Time Frame: Procedure
dissection or perforation
Procedure
Symptomatic Intracranial Cerebral Hemorrhage (SICH)
Time Frame: 24 hour

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.
Outcome Measure
Measure Description
Time Frame
NIHSS score
Time Frame: 24 hours after treatment
The National Institutes of Health Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke

Modified Rankin Score
Time Frame: 90 days after treatment
The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or who have other causes of neurological disability
