    Participants will complete a daily smartphone application-based drug diary recording when they take study drug.

    Time frame: 90 days

  2. Completion of 72-hour voiding diary

    This assessment involves electronic participant documentation of urinary episodes at home.

    Time frame: 90 days

  3. Number of adverse events

    Participants will be followed for adverse events for at least 30 days after the last dose of study drug.

    Time frame: 120 days

Secondary outcomes

  1. Change in urinary incontinence (UI) episodes

    Measured in the 72-hour voiding diary, participant documentation of urinary episodes at home.

    Time frame: Baseline to 90 days

  2. Change in symptoms associated with UI

    Measured on 72-hour voiding diary, participant documentation of urinary episodes at home.

    Time frame: Baseline to 90 days

  3. Change in urinary symptoms associated with neurogenic bladder

    Measured using Neurogenic Bladder Symptom Score - Short Form (NGBSS-SF). NGBSS-SF is a 10 question survey assessing the following domains: bladder management strategy, incontinence, storage \& voiding, consequences, and quality of life. The total score ranges from 0 (no symptoms) to 28 (most severe symptoms). A higher total score indicates greater severity of neurogenic bladder symptoms.

    Time frame: Baseline to 90 days

Other outcomes

  1. Change in Urodynamics - bladder capacity

    Bladder capacity assessment will be performed using pressure sensing urinary and rectal catheters during bladder filling with a solution of saline and iodinated contrast (and emptying if able) with fluoroscopic assessment. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  2. Change in Urodynamics - maximum detrusor pressure

    Max detrusor pressure assessment (cm H20) during bladder storage will be performed using pressure sensing urinary and rectal catheters during bladder filling with a solution of saline and iodinated contrast with fluoroscopic assessment. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  3. Change in Urodynamics - bladder compliance

    Bladder compliance assessment (mL/cm H20) will be performed using pressure sensing urinary and rectal catheters during bladder filling with a solution of saline and iodinated contrast (and emptying if able) with fluoroscopic assessment. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  4. Change in Urodynamics - neurogenic detrusor overactivity (NDO) episodes

    NDO episode (involuntary, sudden contractions of the bladder muscle leading to a strong urge to urinate and potentially causing urine leakage) assessment will be performed using pressure sensing urinary and rectal catheters during bladder filling with a solution of saline and iodinated contrast with fluoroscopic assessment. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  5. Change in Urodynamics - urine leaks

    Urine leak assessment will be performed using fluoroscopy during bladder filling with a solution of saline and iodinated contrast. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  6. Change in Urodynamics - vesicoureteral reflux

    Vesicoureteral reflux assessment will be performed using fluoroscopy during bladder filling with a solution of saline and iodinated contrast. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  7. Change in Urodynamics - bladder neck appearance

    Bladder neck appearance assessment will be performed using fluoroscopic assessment during bladder filling with a solution of saline and iodinated contrast (and emptying or leak if present). This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  8. Change in Urodynamics - bladder shape

    Bladder shape assessment will be performed using fluoroscopy during bladder filling with a solution of saline and iodinated contrast. This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  9. Change in Urodynamics - presence of detrusor sphincter dyssynergia

    Presence of detrusor sphincter dyssynergia assessment will be performed using pressure sensing urinary and rectal catheters, electromyography, and fluoroscopy during bladder filling with a solution of saline and iodinated contrast (and emptying or leaking if present). This assessment will only be completed for the first 10 participants to complete 3 months of treatment.

    Time frame: Baseline to 3 months

  10. Change in Brief Pain Inventory (BPI)

    BPI is a 9 item survey assessing pain severity and impact on quality of life. Participants rate their pain on a scale of 0 to 10, where 10 is the worst pain imaginable. Participants also rate how much the pain interferes with their daily life on a scale of 0 to 10, where 10 is complete interference. Total combined range is 1-10, where pain severity and interference are: Mild: A score of 1-4; Moderate: A score of 5-6; and, Severe: A score of 7-10.

    Time frame: Baseline to 3 months

  11. Change in Neurogenic Bowel Dysfunction Score (NBD)

    NBD is a 10 item system used to assess the severity of bowel dysfunction in individuals with neurological conditions, typically caused by spinal cord injuries, by assigning points based on the frequency and severity of symptoms like bowel movements, incontinence, and discomfort during defecation; a higher score indicates more severe neurogenic bowel dysfunction. The 10-items are scored on an ordinal scale. The NBD weighted score ranges between 0 and 47 points. A higher overall NBD score indicates more severe bowel symptoms. Score 0-6: Very minor; Score 7-9: Minor; Score 10-13: Moderate; and, Score 14+: Severe

    Time frame: Baseline to 3 months

  12. Change in Pittsburgh Sleep Quality Index (PSQI) Questionnaire

    PSQI is a 19 item questionnaire assessing quality of sleep. Each component score ranges from 0 to 3, with 3 indicating the most disturbance. Total score is a number between 0 and 21 that indicates how well someone sleeps. A higher score means worse sleep quality.

    Time frame: Baseline to 3 months

  13. Patient Global Impression Scale (PGI-C)

    The PGI-C is a single question survey assessing change in overall clinical status after intervention. Answers range from Very much improved to Very much worse.

    Time frame: 3 months

  14. Change in International Spinal Cord Injury Quality of Life Basic Data Set (SCI QOL)

    The SCI QOL is a 3-item questionnaire to assess quality of life after spinal cord injury. It is scored on a 10 point Likert scale, with an overall range of 0-30. Lower scores indicate lower satisfaction with quality of life.

    Time frame: Baseline, 3 months, and 4 months

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2026 (actual). Primary completion is estimated for May 2028, 27 months after the start.

Of 44 non-industry phase 2 interventional studies under Spinal Cord Injuries, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 64. This study's planned 27 months is below that.

Counting every sponsor, half of 49 studies reached it within 46 months; a quarter within 28 and three quarters within 64.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
