Endovascular Intervention for Stroke
(TESTED Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine whether endovascular thrombectomy (EVT) is more effective or riskier than standard medical care for individuals who have experienced an ischemic stroke. The focus is on patients who had moderate-to-severe disabilities before their stroke and now have a blockage in a large brain blood vessel. It suits those who have lived with this level of disability for at least three months and have experienced an acute stroke within the last 24 hours. The study compares outcomes between those receiving EVT and those who do not. Participants will help researchers identify which treatment option might offer better recovery or fewer complications. As a Phase 3 trial, this study represents the final step before FDA approval, providing participants an opportunity to contribute to potentially groundbreaking treatment advancements.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that endovascular intervention is safe for stroke patients with moderate-to-severe pre-stroke disability?
Research has shown that endovascular thrombectomy (EVT) is generally safe for treating blockages in large brain vessels during a stroke. One study found EVT to be as safe as medication alone, with patients experiencing no more side effects than those who only took medicine. Another study examined EVT performed more than 24 hours after a stroke and found that, although the benefits were less clear, the safety remained good.
In simpler terms, EVT appears safe, even when performed later than usual. This suggests that the procedure is relatively safe for individuals with severe strokes. However, like any treatment, there are risks, and results can vary. These factors are important to consider when deciding to join a clinical trial.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores the potential of endovascular intervention for stroke patients who already have moderate-to-severe pre-stroke disabilities. Unlike the standard of care, which typically focuses on stroke patients without prior disabilities, this approach targets patients with a pre-existing modified Rankin scale score of 3 or 4, offering a new avenue for treatment. By addressing anterior circulation large vessel occlusions within 24 hours of onset, this method could significantly improve outcomes for a group often overlooked in stroke management. This trial aims to broaden the understanding of stroke treatment efficacy in a more diverse patient population.
What evidence suggests that endovascular intervention is effective for ischemic stroke?
Studies have shown that endovascular thrombectomy (EVT), the treatment under study in this trial, effectively aids recovery from strokes caused by large blood vessel blockages. Research indicates that EVT reduces disability more effectively than medication alone, especially when performed soon after the stroke occurs. Although some studies show mixed results if performed after 24 hours, most agree that EVT is beneficial when used promptly. Overall, EVT has greatly improved the treatment of strokes caused by large vessel blockages.34567
