Trial summary

Stroke prognosis is intimately related to reperfusion. Reperfusion in acute setting can be achieved with different strategies - varying from intravenous rtPA from mechanical thrombectomy. Recently, interventional approaches have been gaining attention and playing an increasing role in stroke care. Read more about this study

About this study

Official title: Randomized Clinical Trial Comparing Intravenous Thrombolysis With Thrombectomy by the Penumbra™ System in Patients With Middle Cerebral Artery Stem Occlusion - Pilot Study

Stroke prognosis is intimately related to reperfusion. Reperfusion in acute setting can be achieved with different strategies - varying from intravenous rtPA from mechanical thrombectomy. Recently, interventional approaches have been gaining attention and playing an increasing role in stroke care. However, no solid scientifical data is available to date. The investigators want do conduct a pilot trial to test if the use of the Penumbra™ System can improve clinical outcomes in a specific stroke setting.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Penumbra™ SystemDevice

    Patients assigned to the Thrombectomy arm will be conducted to the angio suite. Mechanical thrombectomy will be attempted with the use of the Penumbra™ System, and can be assisted by intraarterial thrombolysis (rTPA up to 20 mg)

  • Recombinant tissue plasminogen activatorDrug

    Patients assigned to Usual Care arm will be thrombolysed according to the NINDS protocol (rtPA 0,9 mg/kg, 10% IV bolus and remaining in the next hour, up to 90 mg)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Penumbra™ System and Recombinant tissue plasminogen activator in people with Stroke, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 4 inclusion and 3 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The record says: withdrawn, as of the sponsor's last update on 3 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Functional independence (modified Rankin Scale 0-2) (time frame: 3 months). 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 NCT01133223, which also lists 10 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 3 Sep 2015.
