Study Details

Study Description

Brief Summary

The purpose of this trial is to assess the safety and effectiveness of the Penumbra System as an adjunctive treatment to intravenous (IV) recombinant human tissue plasminogen activator (rtPA)in patients with acute ischemic stroke from large vessel occlusion in the brain. IV rtPA is the only drug approved for the treatment of acute ischemic stroke but it does not work very well in cases where the stroke is caused by a large vessel occlusion. The hypothesis being tested is to determine if the addition of a treatment by a mechanical thrombectomy device like the Penumbra System can improve the clinical outcome of the patient over just using IV rtPA alone.

Condition or Disease Intervention/Treatment Phase
  • Drug: intravenous (IV) recombinant human tissue plasminogen activator (rtPA)
  • Device: Penumbra System
Phase 4

Detailed Description

Current therapies for acute stroke are limited to the intravenous administration of a intravenous (IV) recombinant human tissue plasminogen activator (rtPA) for thrombolysis of the affected cerebral arteries within 3-4.5 hours from symptom onset, and the use of intra-arterial (IA) endovascular mechanical clot retrieval devices within 8 hours from ictus, all of which have limitations as mono therapies. For example, IV rtPA may not be very efficacious in large vessel occlusion and the long term effects of mechanical thrombectomy devices on patient functional outcome is unknown. This is a randomized, concurrent controlled study to assess the safety and effectiveness of the Penumbra System as adjunctive therapy to IV rtPA in the acute intervention of acute ischemic stroke. Patients presenting with symptoms of acute ischemic stroke who have evidence of a large clot burden (clot length > 8mm) in the anterior circulation will be assigned to either IV rtPA therapy alone (0.9mg/kg to a maximum of 90mg) or a combined IV rtPA therapy (0.9mg/kg to a maximum of 90mg) and intra-arterial (IA) adjunctive treatment with the Penumbra System. Each treated patient will be followed and assessed for 3 months after enrollment.

    Outcome Measures

    Primary Outcome Measures

      The assessor is blinded to patient treatment assignment.

    2. Incidence of All Serious Adverse Events [90 days]

      A Serious Adverse Event is defined as an event that: Led to death Led to a serious deterioration in the health of the patient that: Resulted in life-threatening illness or injury Resulted in permanent impairment of a body structure or a body function Required in-patient hospitalization or prolongation of existing hospitalization Resulted in medical or surgical intervention to arrest permanent impairment to body structure or a body function Led to fetal distress, fetal death or a congenital abnormality or birth defect

    Secondary Outcome Measures

    1. Good Clinical Outcome [30 days]

      Good clinical outcome at 30 days post-procedure as defined by a 10 points or more improvement in the NIH stroke scale score at Discharge, a NIH stroke scale score of 0-1 at Discharge; or a 30-day modified Rankin scale score of 0-2

    2. Incidence of Symptomatic and Asymptomatic Intracranial Hemorrhage [90 days]

      A symptomatic intracranial hemorrhage is defined as 24 hour CT evidence of an ECASS defined ICH and a 4-point or more worsening of the NIH Stroke Scale score
