About this study

Official title: Prospective, Multi-Center, Single-Arm Study of Reverse Medical Barrel™ Vascular Reconstruction Device for Adjunctive Treatment to Embolic Coils in Wide-Neck, Intracranial, Bifurcating Aneurysms of Middle Cerebral and Basilar Arteries

Single arm study to evaluate the outcomes of treatment with the Barrel VRD device as an adjunctive treatment to coiling for wide neck, intracranial, bifurcating/branching aneurysms in the middle cerebral and basilar arteries.

Being tested

What is being measured

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

  1. Number of Participants With Neurologic Death or Major Ipsilateral Stroke Within 12 Month Follow-up Period.

    The primary safety endpoint was the number of participants reported with a neurological death or major ipsilateral stroke (National Institute of Stroke Scale (NIHSS) increase of ≥ 4 for > 24 hours) at any time during the follow-up period.

    The NIHSS is a tool used to quantify neurological impairment caused by stroke. The scale interpretation is as follows:

    0: No stroke symptoms 1-4: Minor stroke symptoms 5-15: Moderate stroke 16-20: Moderate to severe stroke 21-42: Severe strokeThe National Institutes of Health Stroke Scale

    Measured: 12 months, after device implant

  2. Number of Participants With Raymond Grade I ( 100%) Occlusion of the Aneurysms for Participants Treated With the Barrel VRD at 12 Months in the Absence of Retreatment, Parent Artery Stenosis, or Target Aneurysm Rupture

    The primary effectiveness endpoint was the count of participants achieving Raymond Grade I (100% occlusion) of the aneurysm treated with the Barrel VRD at 12 months ± 8 weeks in the absence of retreatment, parent artery stenosis (>50%), or target aneurysm rupture

    The Raymond Grade Classification definitions evaluated by an independent core laboratory are as follows:

    Class 1: Complete occlusion - complete obliteration of the aneurysm. Class 2: Residual neck - persistence of any portion of the original defect of the arterial wall as seen on any single projection, but without opacification of the aneurysmal sac.

    Class 3: Residual aneurysm - opacification of the aneurysmal sac

    Measured: 12 months, after device implant

Secondary outcomes (5)
  1. Number of Participants With Successfully Deployed Barrel VRD

    This secondary outcome measure provides the number of subjects successfully implanted with the Barrel VRD.

    Measured: Index Procedure, Day 0

  2. Number of Participants With Raymond Grade I (100% Complete Occlusion) and Raymond Grade II (Residual Neck) for Participants Treated With the Barrel VRD, in the Absence of Retreatment, Parent Artery Stenosis (>50%), or Target Aneurysm Rupture at 12 Months

    This secondary outcome measure provides the count of participants treated with the Barrel VRD with Independent Core Laboratory aneurysm occlusion imaging evaluations of Complete Occlusion (Raymond Grade I) and Residual Aneurysm Neck (Raymond Grade II) at 12 months combined. Subjects with evidence of parent artery stenosis, retreatment, or rupture were not considered success.

    Raymond Grade Scale

    Class 1: Complete occlusion - complete obliteration of the aneurysm. Class 2: Residual neck - persistence of any portion of the original defect of the arterial wall as seen on any single projection, but without opacification of the aneurysmal sac.

    Class 3: Residual aneurysm - opacification of the aneurysmal sac.

    Measured: 12 months, after device implant

  3. Number of Participants With Modified Rankin Score of 0-2 or no Change From Baseline

    This secondary outcome provides the count of participants treated with the Barrel device with a Modified Rankin Score of 0-2 at 12 months or no change from baseline.

    The Modified Rankin Score is a scale for measuring general functionality as follows:

    0: No symptoms at all

    1. No significant disability despite symptoms; able to carry out all usual duties and activities
    2. Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
    3. Moderate disability; requiring some help, but able to walk without assistance
    4. Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance
    5. Severe disability; bedridden, incontinent and requiring constant nursing care and attention
    6. Dead

    Measured: 12 months, after device implant

  4. Number of Participants With Angiographic Evidence of In-stent Stenosis at 12 Months +/- 8 Weeks Reported According to the Following Ordinal Groups: <25%, 25-50%, 51-75%, >75%

    This secondary measure provides the count of participants with parent artery stenosis per an independent core lab evaluation within the following ordinal groups: <25%, 25-50%, 51-75%, >75%.

    Measured: At 12 Months +/- 8 weeks

  5. Number of Participants With Any Cause of Death Within 30 Days or Neurological Death Within 12 Months +/- 8 Weeks

    This secondary outcome measure provides the combined number and percentage of subjects that died within 30 days or had a neurologic death within 12 months of receiving the study device.

    Measured: 30 Days and 12 months +/- 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing BARREL VRD in people with Intracranial Bifurcating Aneurysms, run by Medtronic Neurovascular Clinical Affairs at 3 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 4 inclusion and 10 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 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 5 Dec 2018). 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?

Number of Participants With Neurologic Death or Major Ipsilateral Stroke Within 12 Month Follow-up Period. (time frame: 12 months, after device implant). 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 26 Dec 2018.
