Multi-arm Optimization of Stroke Thrombolysis (MOST): a Single Blinded, Randomized Controlled Adaptive, Multi-arm, Adjunctive-thrombolysis Efficacy Trial in Ischemic Stroke

Washington University School of Medicine·interventional·Posted Nov 8, 2018·Updated Feb 7, 2025

In Brief

A Phase 3 clinical trial evaluating Argatroban, Eptifibatide, and 1 other intervention for Acute Ischemic Stroke. Completed, enrolled 514 participants across 61 sites.

Detailed Summary

The primary efficacy objective of the MOST trial is to determine if argatroban (100µg/kg bolus followed by 3µg/kg per minute for 12 hours) or eptifibatide (135µg/kg bolus followed by 0.75µg/kg/min infusion for two hours) results in improved 90-day modified Rankin scores (mRS) as compared with placebo in acute ischemic stroke (AIS) patients treated with standard of care thrombolysis (0.9mg/kg IV rt-PA or 0.25mg/kg IV tenecteplase or TNK) within three hours of symptom onset. Patients may also receive endovascular thrombectomy (ET) per usual care. Time of onset is defined as the last time the patient was last known to be well.

Interventions

Argatrobandrug

Direct Thrombin Inhibitor - Argatroban is a derivative of arginine that competitively binds to the active site of thrombin thereby preventing fibrin deposition. With a half-life of 30 minutes, argatroban has an immediate anticoagulant effect after IV administration which is rapidly reversed with discontinuation of the drug.

Eptifibatidedrug

GP 2b/3a Receptor Inhibitor - The final step of platelet aggregation is mediated via the GP2b/3a receptor. Eptifibatide was specifically developed to ensure rapid inhibition of platelet aggregation (within 15 minutes), a short half-life (\~2 hours) and rapid dissociation from platelets with 50% restoration of platelet function within 2-4 hours of discontinuation.
