Who may be able to join

About this study

Official title: RandomizEd Trial of reVascularizAtion With Solitaire FR® Device Versus Best mediCal Therapy in the Treatment of Acute Stroke Due to anTerior Circulation Large Vessel Occlusion Presenting Within 8 Hours of Symptom Onset

To evaluate the hypothesis that mechanical embolectomy with the Solitaire FR device is superior to medical management alone in achieving favorable outcome in the distribution of the modified Rankin Scale scores at 90 days in subjects presenting with acute large vessel ischemic stroke < 8 hours from symptom onset.

Read the detailed description

Prospective, multi-center, randomized, controlled, open, blinded-endpoint trial with a sequential design. The randomization employs a 1:1 ratio of mechanical embolectomy with the CE MARK approved stentriever Solitaire FR® versus medical management alone. Randomization will be done under a minimization process using age, baseline NIHSS, therapeutic window and vessel occlusion site. For the primary endpoint, subjects will be followed for 90 days post-randomization.

Interim analysis will be performed as preplanned and interpreted by the Data Safety Monitoring Board (DSMB) after the first 174, 346 and 518 patients representing 25%, 50% and 75% of the planned sample size have completed their 90-day follow-up. The DSMB will advise the executive committee (EC) on recommendations to stop the trial early either for reasons of safety, efficacy, futility or to adjust the sample size. The latter may be necessary as given the paucity of data regarding natural history of the non-treated patients assumptions regarding rates of favorable outcomes in this group of patients may be incorrect. Of note, sample size adjustment based on different than expected outcomes rates is permitted, but it is not permitted to adjust the sample size based on change in the pre-specified treatment effect which is set at 10%.

Subject population: Subjects presenting with acute ischemic stroke within 8 hours from symptom onset and whose strokes are attributable to an occlusion of the internal carotid or proximal MCA (M1) arteries. Subjects are either ineligible for IV alteplase or have received IV alteplase therapy without recanalization.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Solitaire FR device and Medical treatment in people with Acute Stroke, run by Fundacio Ictus Malaltia Vascular at 4 sites in Spain.

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 7 inclusion and 23 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: stopped early, as of the sponsor's last update on 3 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Spain. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 stopped early (reason given: Following DSMB advice after first interim analysis (n=174)). Results are not available in the source record.

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?

Between-group comparison of the distribution of the modified Rankin Scale scores (shift analysis) (time frame: 90 days after enrollment). 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 NCT01692379, which also lists 11 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 Feb 2016.
