Large Artery Occlusion Treated in Extended Time With Mechanical Thrombectomy Trial (LATE-MT)

The LATE-MT trial aims to determine that compared with standard medical care without MT, performing MT in a time window that exceeds 24 hours after last seen well, is superior on the functional outcome in AIS patients due to LVO who have been carefully selected by clinical and imaging criteria. The secondary aims include comparing with standard medical care without MT, to determine whether performing MT exceeding 24 hours of last known well is safe on the risks of any ICH, sICH, and any SAE. Other secondary aims include early improvement in neurological recovery as measured by NIHSS scores at 7 days; successful recanalization rate; imaging measurements of infarct size at 24-48 hours; death or major disability (mRS 3-6); separately on death and disability (mRS 3-5); HRQoL using Euro-QoL EQ-5D questionnaire; utility-weighted modified Rankin scale scores; duration of hospitalization; residence; and hospital service costs.
