The Neuroprotective Effect of Remote Ischemic Conditioning in Aneurysm Coiling Therapy (NEAT)

November 21, 2018 updated by: Ji Xunming,MD,PhD, Capital Medical University

The Neuroprotective Effect of Remote Ischemic Conditioning in Aneurysm Coiling

The overall incidence of DWI positive for thromboembolic events following endovascular treatment of intracranial aneurysms is proximately 50%. Whether remote ischemic conditioning was safe and effective to reduce ischemic brain lesions on DWI after endovascular treatment of intracranial aneurysms is still unclear. The investigators' hypothesis is that remote ischemic conditioning is a safe and effective strategy to reduce new ischemic lesions in intracranial aneurysms patients undergoing endovascular treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Age 18 years or older
  • Unruptured brain aneurysm deemed suitable for neuroendovascular repair
  • Normal baseline brain MRI
  • Female subjects of childbearing potential have a negative pregnancy test.
  • Signed informed consent prior to entering study

Exclusion Criteria:

  • Dissecting or mycotic brain aneurysm.
  • Planned endovascular vessel sacrifice as the primary modality for aneurysm treatment

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: Remote ischemic conditioning
Device: remote ischemic conditioning
Remote ischemic conditioning is performed by using an electric autocontrol device with cuffs that inflated to a pressure of 200 mm Hg during the ischemic period (Patent No. CN200820123637.X, China)
SHAM_COMPARATOR: Sham remote ischemic conditioning
Device: sham remote ischemic conditioning
sham remote ischemic conditioning is performed by using an electric autocontrol device with cuffs that inflated to a pressure of 60 mm Hg

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

The presence of ≥1 new brain lesions on DWI
Time Frame: within 72 hours after endovascular treatment
Assessed by DWI

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.
