NCT04373512 · Status: COMPLETED · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 182

Last updated 2025-05-13

No results posted yet for this study

Summary

The objectives of the proposed research among this population are: 1) to define clinically meaningful change (i.e. differentiating states of health and illness) with respect to urinary symptoms, urine inflammation, cultivable bacteria, and the urine ecosystem; and 2) to determine the optimal intravesical Lactobacillus RhamnosusGG (LGG®) dose to be used to reduce urinary symptoms in a future clinical trial.

Conditions

  • Spinal Cord Injuries
  • Neurogenic Bladder

Interventions

DRUG

Culturelle 10 Billion CFU Capsule (2 doses)

For the LGG instillation, participants will be instructed to mix the contents of 1 LGG capsule into saline. After mixing, participants will draw up the liquid LGG mixture into a syringe and instill via the intermittent catheter after the last catheterization prior to going to bed. Participants will receive 2 LGG capsules and will repeat this process the following night ("Low" dose). Subjects will remain in the study for up to 29 months, with participation ending after one completed intervention (2 doses) and post-intervention assessments are complete. If urinary symptoms do not occur warranting instillation during the ensuing 29 months, participants will be asked to return any remaining capsules

DRUG

Culturelle 10 Billion CFU Capsule (4 doses)

For the LGG instillation, participants will be instructed to mix the contents of 1 LGG capsule into saline. After mixing, participants will draw up the liquid LGG mixture into a syringe and instill via the intermittent catheter after the last catheterization prior to going to bed. Participants will receive 4 LGG capsules and will repeat this process twice daily for a total of four doses ("High" dose). Subjects will remain in the study for up to 29 months, with participation ending after one completed intervention (4 doses) and post-intervention assessments are complete. If urinary symptoms do not occur warranting instillation during the ensuing 29 months, participants will be asked to return any remaining capsules
