  Purpose
This is an open label single center phase II trial, evaluating the utility of 64 slice CT perfusion (CTP) in acute ischemic stroke (AIS) patients. The main aim is to determine which aspects of CTP imaging can aid in expanding the time window for thrombolysis with IV (rt-PA) in AIS patients up to 6 hours after symptom onset.

Condition Intervention
Ischemic Stroke Other: Computed tomography perfusion imaging

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Expanding the Time Window for IV Thrombolysis With Rt-PA in Acute Ischemic Stroke Patients Using Computed Tomography Perfusion Imaging: The PERFusion Use in Stroke Evaluation (PERFUSE) Study

Further study details as provided by Nobl Barazangi, California Pacific Medical Center Research Institute:

Primary Outcome Measures:
  • Final infarct volume [ Time Frame: 24 hour post-thrombolysis ]

Secondary Outcome Measures:
  • Large vessel occlusion on neuroimaging [ Time Frame: 24 hours post-thrombolysis ]
  • NIHSS [ Time Frame: 24-hours from tPA adminsitration ]
  • Symptomatic intracerebral hemorrhage post-thrombolysis [ Time Frame: 24 hours post-thrombolysis ]
  • Modified Rankin Scale [ Time Frame: 3-months from tPA administration ]

Estimated Enrollment: 100
Study Start Date: May 2011
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Acute ischemic stroke patients
All acute ischemic stroke patients receiving IV rt-PA within 6 hours of symptom onset
Other: Computed tomography perfusion imaging
As per standard of care at CPMC
