  • Signed informed consent from patient or legally authorized representative.

Who cannot join

  • CT or MRI evidence of recent/ fresh hemorrhage on presentation.
  • Clinical history, past imaging or clinical judgment suggests that the intracranial occlusion is chronic.
  • Rapidly improving neurological deficits based on the investigator's clinical judgement.

About this study

Official title: A Prospective, Multi-Center, Single Arm Study to Evaluate the DAISe System During Neurointervention for Acute Ischemic Stroke

This purpose study is to demonstrate the safety and performance of the DAISe System used to remove clot in the brain during a stroke. This study will assess how well the device removes clot from the brain and how well patients recover from their stroke. This study plans to enroll 100 study patients at up to 10 hospitals in Europe. Study patients are followed for 3 months after the procedure.

Read the detailed description

The study is a prospective, multi-center, single arm study that will enroll a maximum of 90 subjects, plus up to 50 roll-in subjects. A maximum of 10 sites in Europe will be involved in this study. The primary performance endpoint is successful revascularization defined as TICI 2b-3 flow in the target vessel post-treatment of up to three passes with the DAISe System. The primary safety endpoint is symptomatic intracranial haemorrhage at 24 hours post-procedure as detected by CT/MRI with an NIHSS change of >/=4. Subject will be followed through hospital discharge with a visit at Day 1 post procedure, Day 7 or prior to discharge/transfer, 30 days and 3 months.

What participants receive

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

  • DAISe SystemDevice

    The DAISe System is indicated for revascularization of patients with acute ischemic stroke for the removal of fresh thrombi from vessels in the neurovasculature.

Receives: Device: DAISe System

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants with successful revascularization

    Defined as mTICI 2b-3 flow in the target vessel post-treatment of up to three passes with the DAISe System.

    Measured: intra-procedural

  2. Rate of symptomatic intracranial haemorrhage

    24 hours post-procedure as detected by CT/MRI with an NIHSS change of >4

    Measured: 12-36 hours post procedure

Secondary outcomes (9)
  1. Number of participants with successful revascularization of mTICI 2b-3 as a result of the first attempt with the DAISe System

    Measured: intra-procedural

  2. Number of participants with successful revascularization of mTICI 3 as a result of the first attempt with the DAISe System

    Measured: intra-procedural

  3. Number of participants with successful revascularization of final mTICI 2b-3 at the end of the procedure

    Measured: intra-procedural

  4. Time from groin puncture to successful revascularization defined as final mTICI 2b-3 flow

    Measured: intra-procedural

  5. Rate of procedure-related complications

    Measured: post procedure through discharge

  6. Rate of embolization to a new vascular territory (ENT)

    Measured: intra-procedural

  7. Good functional outcome for participants measured by Modified Rankin Scale score of 0-2.

    The Modified Rankin Scale (mRS) measures neurological disability or dependence for stroke patients on a scale of 0 (no symptoms) to 6 (deceased).

    Measured: 30 days and 3 months post procedure

  8. Quality of life for participants: PROMIS Scale

    PROMIS Scale

    Measured: 3 months post procedure

  9. Rate of all cause mortality

    Measured: 30 days and 3 months post procedure

Questions about this trial

What is this clinical trial studying?

A study testing DAISe System in people with Stroke, Acute, run by MIVI Neuroscience, Inc. at 2 sites in Belgium.

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 17 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 20 Oct 2022. 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 Belgium. 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?

The study was stopped early (reason given: Device modifications). 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?

Number of participants with successful revascularization (time frame: intra-procedural). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Oct 2022.
