Multi-arm Optimization of Stroke Thrombolysis
- 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.

Group Intervention Description Placebo Placebo - Argatroban Argatroban 100µg/kg bolus followed by 3µg/kg per minute for 12 hours Eptifibatide Eptifibatide 135µg/kg bolus followed by 0.75µg/kg/min infusion for two hours
- Primary Outcome Measures
Name Time Method 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
Name Time Method Percentage of Participants With NIHSS Less Than or Equal to 2 at 24 Hours 24 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 NIHSS 24 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.
90-day mRS 90 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-5D 90 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 3 baseline 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
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.
