About

TESTED will compare the risks and benefits of endovascular thrombectomy (EVT) to medical management (no EVT) in ischemic stroke patients who have a blockage in one of the large blood vessels in the brain and have a moderate-to-severe disability prior to their stroke.

Full description

People with disabilities can suffer acute ischemic stroke (AIS). Endovascular clot removal is a breakthrough therapy for large vessel occlusion (LVO) AIS. Pre-stroke disabled patients were excluded from pivotal EVT stroke trials, so whether EVT is effective for those with pre-stroke disability is not known. As a result, two competing, widely-practiced, treatment paradigms have emerged based on individual practitioners' extrapolation of EVT benefits and safety from patients without a pre-stroke disability to those with disability: 1) Multimodal Medical Management (MMM; using intravenous thrombolysis, antiplatelets, anti-hypertensives, cholesterol lowering medications, and other rehabilitative measures, as indicated) without EVT, and 2) EVT with the background of MMM.

TESTED will enroll patients with LVO-AIS who have a pre-existing disability, defined as pre-stroke modified Rankin score (mRS) 3 and 4, at 12 geographically distinct comprehensive stroke centers serving diverse race-ethnic and socioeconomic populations. The central objective of TESTED is to determine the comparative effectiveness and safety of these two different practice paradigms.
