|Condition or disease||Intervention/treatment||Phase|
|Stroke||Drug: Alteplase t-PA||Phase 2|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||100 participants|
|Intervention Model:||Parallel Assignment|
|Official Title:||Echoplanar Imaging Thrombolysis Evaluation Trial (EPITHET) in Acute Stroke|
|Study Start Date :||August 2001|
|Estimated Study Completion Date :||April 2007|
- Primary Hypothesis - lesion growth
- In patients with penumbra, there will be attenuation of lesion growth (outcome T2 lesion volume - acute DWI volume ) with tPA.
- Secondary Hypotheses
- In the non-penumbral group, lesion growth will be lower and will not be attenuated by tPA.
- Favourable functional outcome (mRS 0-2) will be more likely in patients with penumbra receiving tPA.
- That the proportion of patients achieving good neurological outcome (an 8 point improvement in NIH-SS or outcome NIH-SS of 0, 1) will be greater in those patients with a penumbra receiving tPA.
- Symptomatic hemorrhagic transformation (sICH) will be predicted by the size of the baseline DWI volume in those patients receiving tPA.
- Reperfusion (greater than 90% PWI lesion reduction, or recanalisation on MRA, between the acute and sub-acute interval), will be increased (in patients with penumbra) receiving tPA.
- In patients with malignant mismatch (Definition DWI 100ml or more and / or PWI 100ml or more) there will be unfavourable clinical outcome (even if there is attenuation of growth).
