About this study

Official title: Pilot Trial of the Vibrant Capsule for Spinal Cord Injury Neurogenic Bowel Dysfunction

The goal of this study is to test the safety and effectiveness of Vibrant capsules in spinal cord injury patients with neurogenic bowel.

Read the detailed description

The purpose of this study is to see how well the Vibrant capsule works at treating people with spinal cord injury (SCI)-induced upper motor neuron (UMN) neurogenic bowel. This study will test the safety of the Vibrant capsule. This Vibrant capsule has been approved by the Food and Drug Administration (FDA) for chronic idiopathic constipation.

What participants receive

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

  • Vibrant CapsuleDevice

    The Vibrant capsule is designed to alleviate chronic constipation by stimulating the colon through gentle vibrations. The Vibrant capsule will be swallowed and tracked through the digestive system of spinal cord injury patients.

What is being measured

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

  1. Safety of Vibrant capsule as indicated by number of participants who had an adverse event

    Measured: baseline week 1, baseline week 2, baseline week 3, baseline week 4

  2. Safety of Vibrant capsule as indicated by number of participants who had an adverse event

    Measured: week 1 with treatment, week 2 with treatment, week 3 with treatment, week 4 with treatment, week 5 with treatment, week 6 with treatment, week 7 with treatment, week 8 with treatment

  3. Safety of Vibrant capsule as assessed by the Penn Spasm Frequency Scale (PSFS)

    The total score on the Penn Spasm Frequency Scale (PSFS) ranges from 0 to 7, and a higher score indicates greater spasm frequency and severity.

    Measured: baseline week 1, baseline week 2, baseline week 3, baseline week 4

  4. Safety of Vibrant capsule as assessed by the Penn Spasm Frequency Scale (PSFS)

    The total score on the Penn Spasm Frequency Scale (PSFS) ranges from 0 to 7, and a higher score indicates greater spasm frequency and severity.

    Measured: week 1 with treatment, week 2 with treatment, week 3 with treatment, week 4 with treatment, week 5 with treatment, week 6 with treatment, week 7 with treatment, week 8 with treatment

  5. Safety as assessed by average weekly Numerical Pain Score

    The Numerical Pain Score ranges from 0 to 10, with a higher score indicating greater pain.

    Measured: baseline week 1, baseline week 2, baseline week 3, baseline week 4

  6. Safety as assessed by average weekly Numerical Pain Score

    The Numerical Pain Score ranges from 0 to 10, with a higher score indicating greater pain.

    Measured: week 1 with treatment, week 2 with treatment, week 3 with treatment, week 4 with treatment, week 5 with treatment, week 6 with treatment, week 7 with treatment, week 8 with treatment

  7. Safety as assessed by the Neurogenic Bladder Symptom Score (NBSS)

    The Neurogenic Bladder Symptom Score (NBSS) ranges from 0 to 96, with a higher score indicating greater Neurogenic Bladder Symptoms.

    Measured: baseline, week 3

  8. Safety as assessed by the Neurogenic Bladder Symptom Score (NBSS)

    The Neurogenic Bladder Symptom Score (NBSS) ranges from 0 to 96, with a higher score indicating greater Neurogenic Bladder Symptoms.

    Measured: week 1 with treatment, week 4 with treatment, week 8 with treatment

Secondary outcomes (2)
  1. Feasibility as indicated by the number of participants that adhere to the prescribed use of Vibrant

    Feasibility of the Vibrant capsule will be recorded in this patient population by adherence to the protocol.

    Measured: from week 1 with treatment to week 8 with treatment

  2. Feasibility of using the Vibrant capsule as indicated by a satisfaction survey

    Feasibility will also be recorded by a satisfaction survey completed by the study participant. Total score ranges from 0 to 40, with a higher score indicating higher satisfaction.

    Measured: end of study (8 weeks after start of treatment)

What does the primary outcome measure?

Safety of Vibrant capsule as indicated by number of participants who had an adverse event (time frame: baseline week 1, baseline week 2, baseline week 3, baseline week 4). The study lists 8 primary outcomes in all. 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 NCT07213986, which also lists 4 linked publications.
