About this study

Official title: Non-Invasive Neurostimulation of the Vagus Nerve With the GammaCore Device for the Prevention of Chronic Migraine

The purpose of this multi-center, prospective, double-blind, randomized, sham-controlled pilot study is to study feasibility and collect preliminary clinical data related to the safety and clinical benefits of daily use of non-invasive vagal nerve stimulation with the GammaCore device for the prevention of chronic migraine, and to support the development and approval of a larger pivotal study.

What is being measured

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

  1. Safety - Number of Participants With Adverse Events

    Safety was assessed by collecting Adverse Effects

    Measured: Up to 8 weeks - duration of the Randomized period

Secondary outcomes (4)
  1. Mean Change in Headache Days

    Mean change in headache days. Change between 4 week run in period to the 8 weeks randomized period.

    Measured: Run-in period (4 weeks no treatment) and Randomized period (8 weeks)

  2. Total Number of Headache Days Per Arm With Peak Severity of Mild, Moderate, or Severe

    Peak severity per headache day was reported each headache day in the subject diary. Pain was reported as mild, moderate or severe. Whereas as mild = least severe and severe = most severe.

    Measured: Run-in (4 weeks no treatment) and Randomized (8 weeks)

  3. Use of Pain Relief Medication

    All abortive headache medication taken during randomized period

    Measured: Randomized period - 8 weeks

  4. Mean Change in Quality of Life Short Form Survey (SF-12)

    The Quality of Life Short Form Survey (SF-12) is a multipurpose short form survey with 12 questions that are combined, scored and weighted to create two scales that provide glimpses into mental and physical functioning and overall health-related-quality of life. The SF-12 is weighted and summed to provide easily interpretable scales for physical and mental health. Physical and Mental Health Composite Scores (PCS \& MCS) are computed using the scores of the twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.

    SF-12 were recorded in the subject diary at the Phase 1 follow-up visit (week 4) and during Phase 2 randomized period at week 4 and week 8.

    Measured: Run-in (4 weeks) and Randomized period (8 weeks)

Questions about this trial

What is this clinical trial studying?

A study testing GammaCore Active Device in people with Chronic Migraine, run by ElectroCore INC at 6 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 7 inclusion and 20 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 20 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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. Some participants in this study may receive a placebo. 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 20 Jun 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?

Safety - Number of Participants With Adverse Events (time frame: Up to 8 weeks - duration of the Randomized period). 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 NCT01667250, which also lists 1 linked publication.

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 Jun 2018.
