Feasibility Study of IV rtPA vs. Primary Endovascular Therapy for Acute Ischemic Stroke
Study type: Interventional What is this?
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
This pilot trial will be the first step toward direct comparison of delivery of endovascular reperfusion therapy to intravenous rt-PA in a time-to-treatment framework shown as most effective by the NINDS rt-PA Stroke Trial. A randomized trial is justified for the following reasons: 1) The high rate of death and disability associated with ischemic stroke despite treatment with intravenous rt-PA mandates critical analysis of alternate therapies with therapeutic potential, 2) endovascular treatment for acute ischemic stroke is expanding in North America without compelling evidence of safety and efficacy from well-designed clinical trials, 3) critical cost-effectiveness analysis cannot be done without acquiring pertinent outcomes data from controlled studies.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
