About this study

Official title: A Randomized Controlled Pilot Study to Examine the Efficacy of Greater Occipital Nerve (C2) Stimulation in the Treatment of Fibromyalgia

The study is designed as a prospective, randomized, double-blind, single center study with a 6 month duration post permanent system implantation. Forty patients will be implanted.

During trial stimulation, patients will be randomized into one of two study arms for two weeks. Crossover will occur at the 2 week study visit to the opposite group. After completion of these two arms, every patient will subsequently complete participation in the third study arm.

After completion of the third arm, patients will be evaluated to determine if they are a positive responder responder. If so, the patient will have the option of obtaining the permanent implant.

What is being measured

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

  1. Fibromyalgia Impact Questionnaire (FIQ)

    The Fibromyalgia Impact Questionnaire (FIQ) is a self administered scale that was developed to measure fibromyalgia patient status, progress and outcomes. It measures the components of health that are most affected by fibromyalgia. The maximum score is 100 and a higher score indicates a greater impact of the syndrome on the person.

    The change in the Fibromyalgia Impact Questionnaire (FIQ) will be analyzed and reported.

    Measured: End of 6 week stimulation trial

Questions about this trial

What is this clinical trial studying?

A study testing Occipital Stimulation in people with Fibromyalgia, run by Abbott Medical Devices at 1 site 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 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 30 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Fibromyalgia Impact Questionnaire (FIQ) (time frame: End of 6 week stimulation trial). 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 30 Jan 2019.
