Multi-arm Optimization of Stroke Thrombolysis

Phase 3
Active, not recruiting
Conditions
Acute Ischemic Stroke
Interventions
Registration Number
NCT03735979
Lead Sponsor
Washington University School of Medicine
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.

  19. Received Low Molecular Weight heparins (such as Dalteparin, Enoxaparin, Tinzaparin) in full dose within the previous 24 hours

  20. Abnormal PTT within 48 hours prior to randomization after receiving heparin or a direct thrombin inhibitor (such as bivalirudin, argatroban, dabigatran or lepirudin)

  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

Primary Outcome Measures
NameTimeMethod
90-day Utility Weighted Modified Rankin Scores (UW-mRS)90 days after randomization

The modified Rankin scale is a 7 point ordinal scale ranging from 0="no symptoms" to 6="death" . For the primary analysis, the scale was analyzed with patient-centered utility weights. We assigned the following utility weights to the seven levels: 10, 9.1,, 7.6, 6.5, 3.3, 0, 0 (with higher scores indicating a better outcome).

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With NIHSS Less Than or Equal to 2 at 24 Hours24 hours after randomization

National Institute of Health Stroke Scale (NIHSS) scores range from 0 to 42, with higher scores indicating worse neurologic deficit. This is a dichotomous analysis with a cutpoint of 0,1,2 defining the event.

Change From Baseline to 24-hour NIHSS24 hours after randomization

National Institute of Health Stroke Scale (NIHSS) scores range from 0 to 42, with higher scores indicating worse neurologic deficit.

Percentage of Participants With 90-day mRS 0 or 1 (or Return to Their Historical mRS)90 days after randomization

The modified Rankin scale (mRS) is a 7 point scale ranging from 0="no symptoms" to 6="death" where lower scores are better outcomes. For patients with a pre-stroke mRS of greater than 0 or 1, these patients had to return to their historical (pre-stroke) value to be counted as a success.

Percentage of Participants With 90-day mRS 0, 1 or 2 (or Return to Their Historical mRS)90 days after randomization

modified Rankin scale is a 7 point scale ranging from 0="no symptoms" to 6="death" where lower scores are better outcomes.

90-day mRS90 days after randomization

modified Rankin scale is a 7 point ordinal scale ranging from 0="no symptoms at all" to 6="death" where lower scores are better outcomes.

90-day EQ-5D90 days after randomization

EuroQol Five-Dimension (EQ-5D) is a measure of health-related quality of life ranging from -0.59 to 1 where 1 is the best possible health state.

Pre-thrombectomy Modified TICI Score of 2B.baseline

The modified thrombolysis in cerebral infarction (TICI) score prior to endovascular thrombectomy procedure. The modified pre-thrombectomy TICI score is a 4 point scale with possible values of 0, 1, 2A, and 2B. The values are defined as follows: 0=No flow, 1=Penetration without distal branch filling, 2A=\<50% partial reperfusion, and 2B=50%-99% partial reperfusion.

Post-thrombectomy Modified TICI Score of 2B or 3baseline

The modified thrombolysis in cerebral infarction (TICI) score prior to endovascular thrombectomy procedure. The modified post-thrombectomy TICI score is a 5 point scale with possible values of 0, 1, 2A, 2B, 3. The values are defined as follows: 0=No flow, 1=Penetration without distal branch filling, 2A=\<50% partial reperfusion, 2B=50%-99% partial reperfusion, and 3=Completed reperfusion
