DAWN trial data published: Compelling evidence in treating late window & wake-up stroke patients

The New England Journal of Medicine published the results of the DAWN Trial, the trial was designed to evaluate functional outcomes at 90 days in stroke patients treated with mechanical thrombectomy using the Trevo Retriever, from Stryker, compared to those receiving medical therapy alone. Patients were screened for inclusion in the trial if they had a stroke that started within six to 24 hours, or a stroke with an unknown time of onset -- a significantly longer treatment window than the currently cleared thrombectomy indication.

This trial is the first to provide compelling evidence in treating late window and wake-up stroke patients with mechanical thrombectomy. Currently, less than one in 10 patients suffering from an ischemic stroke receives thrombectomy, due in part to a lack of scientific evidence supporting treatment beyond six hours.
