Trial summary

Sacral nerve stimulation (SNS) has become a well-established treatment for patients with fecal incontinence since 1995. The mechanism of action of SNS is still not fully understood but recent studies have shown that the motility of the whole colon is modulated during the stimulation. Read more about this study

About this study

Official title: Treatment of Irritable Bowel Syndrome (IBS) With Sacral Nerve Stimulation. A Blinded, Randomized Crossover Study

Sacral nerve stimulation (SNS) has become a well-established treatment for patients with fecal incontinence since 1995. The mechanism of action of SNS is still not fully understood but recent studies have shown that the motility of the whole colon is modulated during the stimulation. This modulation of the colonic motility could be a potential mechanism of an action to relieve the symptoms in patients with IBS.

Twenty eight patients with IBS will be enrolled in the study. They have to meet the ROME III criteria, and also satisfy the criteria for implantation of a neurostimulator.

After a post implantation period where the programming of the neurostimulator is optimised, the patient is randomized in a double blinded design to receive either ON-OFF or OFF-ON stimulation in a 2-month period.

At the end of each period (ON/OFF) the patient will be examined with Magnet Tracking System (MTS) for motility and with impedance planimetry including thermal stimulation (circulating water)for multimodal sensory testing of the rectum.

This is based on the study hypothesis that the motility of the small intestine and the colon is changed in IBS patients according to their subtype (Diarrhoea-IBS, Constipation-IBS and Disordered bowel habit-IBS) compared to healthy persons. And that SNS will affect the motility of the small intestine and the colon in IBS patients as well as SNS will affect the perception of pain/discomfort in the rectum in IBS patients.

The effect of ON-OFF-sacral nerve stimulation on the IBS patients and thereby their IBS symptoms will also be evaluated by an IBS score (GSRS-IBS)and on quality of life by an IBS Impact Scale (IBS-IS) as well as the significance of placebo effect in the treatment of patients with IBS with SNS will be evaluated.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sacral nerve stimulationDevice

    Also called Irritable Bowel Syndrome

    The stimulation is set individually to provide the best possible stimulation for each individual person. This setting is found before the study starts and will not be altered during the study.

What is being measured

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

  1. Comparing the investigations with MTS and impedance planimetry as well as the GSRS-IBS and IBS-IS scores in the the two periods (ON/OFF periods) in the single IBS patient. Nonparametrics tests.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Sacral nerve stimulation in people with Irritable Bowel Syndrome, run by University of Aarhus at 1 site in Denmark.

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 4 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 17 May 2018. 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 Denmark. 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?

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?

Comparing the investigations with MTS and impedance planimetry as well as the GSRS-IBS and IBS-IS scores in the the two periods (ON/OFF periods) in the single IBS patient. Nonparametrics tests. (time frame: 2 months). 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 NCT00919672, 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 17 May 2018.
