Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The following parameters will be evaluated as part of this study:

  • Aneurysm morphology
  • Aneurysm size
  • For ruptured aneurysms: Hunt and Hess Classification of Subarachnoid Hemorrhage (SAH)
  • Size of the embolization device(s) used in the procedure
  • Intra-procedural assessment of aneurysm occlusion and flow stasis
  • Degree of aneurysm occlusion post-procedure (percentage occlusion, Raymond Scale and other scores as appropriate)
  • Aneurysm occlusion durability
  • Recanalization rate
  • Device-related changes in Modified Rankin Scale from baseline
  • Complications/adverse events
  • Rebleed/new bleed

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Subjects with:

- Diameter and width of the aneurysm is appropriate size for treatment with the WEB Aneurysm Embolization System per device Instructions for Use

Description

Inclusion Criteria:

  • Must be at least 18 years of age
  • Must sign and date an IRB/EC-approved written informed consent prior to initiation of any study procedures

Exclusion Criteria:

  • Must not have clinical or angiographic evidence of vasospasm
  • Must not have lesion with characteristics unsuitable for endovascular treatment
  • Must not have neurologic or psychiatric conditions, which preclude ability to comply with all aspects of the screening, evaluation, treatment, and the post-procedure follow-up schedule
  • Must not be concurrently involved in another investigational or post-market study
  • Must not have received any investigational device for treatment of the target intracranial aneurysm prior to entry into this trial

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Durability of occlusion
Time Frame: 6 months
Evaluated by the Corelab
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Recurrence/recanalization rate
Time Frame: 6 months
Evaluated by the Corelab, based on Raymond Roy occlusion scale
6 months
Modified Raymond Scale
Time Frame: 6 months
Evaluation of patient's functional level of activity by the physician
6 months
Percentage occlusion of target aneurysm
Time Frame: 6 months
Evaluated by the Corelab
6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 1, 2015

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
