  21. Received Factor Xa inhibitors (such as Fondaparinaux, apixaban or rivaroxaban) within the past 48 hours
  22. Received glycoprotein IIb/IIIa inhibitors within the past 14 days
  23. Pre-existing neurological or psychiatric disease which confounded the neurological or functional evaluations e.g., baseline modified Rankin score >3
  24. Other serious, advanced, or terminal illness or any other condition that the investigator felt would pose a significant hazard to the patient if rt-PA, TNK, eptifibatide or argatroban therapy was initiated

    a. Example: known cirrhosis or clinically significant hepatic disease

  25. Current participation in another research drug treatment or interventional device trial - Subjects could not start another experimental agent until after 90 days
  26. Informed consent from the patient or the legally authorized representative was not or could not be obtained
  27. High density lesion consistent with hemorrhage of any degree

5. Study Description

Brief 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.

Arm Type

Intervention Type
Drug
Intervention Name(s)
Argatroban
Intervention Description
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.
Intervention Type
Drug
Intervention Name(s)
Eptifibatide
Intervention Description
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.
