Efficacy Study of Pudendal Neuromodulation for the Treatment of Neurogenic Overactive Bladder (ACCEPTANCE)

January 30, 2019 updated by: MedtronicNeuro

Phase IV, Multi-center, Randomized, Cross-over Study to Demonstrate the Efficacy of Pudendal Neuromodulation for the Treatment of Neurogenic Overactive Bladder

The study is designed to demonstrate that treatment with low level stimulation of the bladder muscles reduces symptoms of urinary incontinence in comparison with no stimulation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

The Medtronic InterStim device delivers stimulation therapy for the treatment of chronic intractable (functional) disorders of the pelvis and lower urinary or intestinal tract through the sacral nerve or the pudendal nerve systems.

This trial is designed to demonstrate that neuromodulation of the pudendal nerve will effectively treat patients with neurogenic overactive bladder. Symptoms of urinary incontinence are compared when stimulation is switched on for 4 weeks to stimulation switched off for 4 weeks. After the eight week crossover period, all patients receive treatment and are followed up within the study for 12 months post implant.

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

Description

Inclusion Criteria:

  • Incomplete upper motor neuron lesion
  • Detrusor overactivity
  • Two leaks or two notices of leaks per day
  • Mean functional bladder capacity (volume voided per episode) of ≥100 ml

Exclusion Criteria:

  • Complete spinal lesion or complete bilateral lesion of sacral / pudendal nerves.

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
Time Frame
Functional Bladder Capacity
Time Frame: Baseline, 4 weeks after implant, 8 weeks after implant
Functional Bladder capacity is measured as the average passed volume per episode, in milliliters, as recorded in the patient's voiding diary during the observation period. Due to the small number of patients in each group, the summary on the functional bladder capacity was provided for the combined groups.
Baseline, 4 weeks after implant, 8 weeks after implant
