What is being measured
The primary outcome is the main question the study is designed to answer.
Recanalization [Thrombolysis in Myocardial Infarction (TIMI) 2 or 3] Without Symptomatic Intracranial Hemorrhage
Successful arterial recanalization of occluded target vessel measured by Thrombolysis in Myocardial Infarction (TIMI) score of 2 or 3 following the use of the SOLITAIRE™ or MERCI® Device without any symptomatic intracranial hemorrhage and rescue therapy within 3 passes.
Thrombolysis in Myocardial Infarction (TIMI) score describes the distal flow perfusion and revascularization before and following therapy.
TIMI 0 - No perfusion (worst outcome) TIMI 1 - Perfusion past the initial occlusion, but no distal branch filling TIMI 2 - Perfusion with incomplete or slow distal branch filling TIMI 3 - Full perfusion with filling of all distal branches (best outcome)
Measured: Immediately post treatment
Study Device-related Serious Adverse Events (SAEs)
Incidence of study device-related Serious Adverse Events (SAEs)
Measured: 90 Day
Procedure-related Serious Adverse Events (SAEs)

Secondary outcomes (6)
Time to Initial Recanalization
Time from guide catheter placement to first visualization of Thrombolysis in Myocardial Infarction (TIMI) 2 flow
Measured: post treatment
Good Neurological Outcome at 30 Days
Good neurological outcome, defined as modified Rankin scale (mRS) ≤ 2, or equal to the prestroke mRS if the prestroke mRS was higher than 2, or National Institutes of Health Stroke Scale (NIHSS) score improvement of 10 points or more
Measured: 30 Days Follow-up
Good Neurological Outcome 90 Days
Good neurological outcome, defined as modified Rankin scale (mRS) ≤ 2, or equal to the prestroke mRS if the prestroke mRS was higher than 2, or National Institutes of Health Stroke Scale (NIHSS) score improvement of 10 points or more
Measured: 90 Days Follow-up
Mortality
Rate of Mortality
Measured: 90 Days follow-up
Symptomatic Intracranial Hemorrhage
Symptomatic hemorrhage within 24 hours of procedure. Symptomatic hemorrhages is defined as any parenchymal hematoma 1 (PH1), parenchymal hematoma 2 (PH2), intraparenchymal hemorrhage remote from the ischemic field (RIH), intraventricular hemorrhage (IVH), and subarachnoid hemorrhage (SAH) associated with a worsening of National Institutes of Health Stroke Scale (NIHSS) ≥ 4 within 24hrs.
Measured: 24 hours
Non-fatal Stroke-related Morbidity
Morbidity data is presented in terms of subjects with permanent deficit as a result of one or more adverse events
Measured: 90 Day

Questions about this trial
What is this clinical trial studying?
A study testing SOLITAIRE™ Device and MERCI® Device in people with Ischemic Stroke, run by Medtronic Neurovascular Clinical Affairs at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 26 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recanalization [Thrombolysis in Myocardial Infarction (TIMI) 2 or 3] Without Symptomatic Intracranial Hemorrhage (time frame: Immediately post treatment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01054560, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2016.
