Trial summary

Participants receiving neuromodulation treatment for overactive bladder symptoms will be routinely fitted with an impulse generator. However, the setting on the impulse generator will be set to either intermittent or continuous stimulation. Participants will complete voiding logs and surveys for a month.

About this study

Official title: Intermittent Versus Continuous Stimulation in Bilateral Sacral Neuromodulation for Overactive Bladder

Participants receiving neuromodulation treatment for overactive bladder symptoms will be routinely fitted with an impulse generator. However, the setting on the impulse generator will be set to either intermittent or continuous stimulation. Participants will complete voiding logs and surveys for a month. Battery life will be interrogated.After a one week period were the device is turned off, the impulse generator will be turned to the opposite setting (intermittent or continuous) and the one month period will be repeated. Again, voiding logs, surveys, and battery life will be collected.

The purpose of this project is to investigate the outcomes of intermittent versus continuous stimulation in patients treated with sacral neuromodulation (SNM) for refractory overactive bladder (OAB) syndrome. In addition, the potential for an improved battery life with intermittent stimulation will be quantified.

Read the detailed description

The objective of this project is to investigate the outcomes of intermittent versus continuous stimulation in patients treated with sacral neuromodulation (SNM) for refractory overactive bladder (OAB) syndrome. In addition, the potential for an improved battery life with intermittent stimulation will be quantified. Manufacturers recommended settings for newly implanted impulse generators (IPG); however, no standardized recommendations exist for further adjustments. Quality studies examining IPG parameters are lacking, partly due to the numerous setting variables, which can result in a multitude of permutations. When programming an IPG, an option for cycling simulation (16 seconds on, 8 seconds off) is available. It is theorized that because of a "carryover" effect, symptom relief will continue despite the stimulator being off. The potential benefit of the intermittent stimulation is an improved battery life, which may translate into a less frequent need for reimplantation with less morbidity. Participants receiving neuromodulation treatment for overactive bladder symptoms will be routinely fitted with an impulse generator in a pre-study phase. Patients who experience significant symptomatic improvement will receive a full bilateral sacral neuromodulator implantation and will be randomized to either intermittent or continuous stimulation. Participants will fill out voiding logs and surveys over a 12 week period. At that point, a one-week washout period during which the neuromodulator will be turned off. The impulse generator will then be turned to the alternate setting (intermittent or continuous) and the 12 week period will be repeated. Questionnaires and voiding diaries will be collected at each clinic visit. In total, subject participation will last approximately 25 weeks after full implantation of the bilateral leads and pulse generator.

What is being measured

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

  1. Overactive Bladder Symptoms

    Symptom improvement with be tracked for overactive bladder symptoms through voiding logs and questionnaires.

    Measured: Week 0, 2, 12, 13, 15, 25

Secondary outcomes (1)
  1. Battery Life

    Battery life of the implanted device will be interrogated at each follow up visit to measure longevity of battery.

    Measured: Week 0, 1, 12, 13, 15, 25

Questions about this trial

What is this clinical trial studying?

A study testing Intermittent or Continuous Setting RestorePrime Implanted Impulse Generator in people with Overactive Bladder, run by Loma Linda University at 1 site 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 2 inclusion and 12 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: withdrawn, as of the sponsor's last update on 26 Jan 2015. 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 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. 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 was withdrawn before enrolling participants, so there are no results.

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?

Overactive Bladder Symptoms (time frame: Week 0, 2, 12, 13, 15, 25). 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 NCT02112786, which also lists 2 linked publications.

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 26 Jan 2015.
