What this trial studies

This study evaluates the effectiveness of the Navina Smart transanal irrigation system compared to standard bowel care in patients with Multiple Sclerosis who experience neurogenic bowel dysfunction. It is a randomized, controlled, multicenter trial involving 92 subjects, each participating for 8 weeks with two scheduled site visits. The goal is to determine if the Navina Smart system provides superior bowel management outcomes. Participants will be assessed based on their bowel symptoms and quality of life improvements.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of Multiple Sclerosis and neurogenic bowel dysfunction.

Not a fit: Patients with anal or colorectal stenosis, active inflammatory bowel disease, or other severe gastrointestinal conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved bowel management and quality of life for patients with Multiple Sclerosis.

How similar studies have performed: Previous studies have shown promise in using transanal irrigation for bowel management, suggesting potential success for this approach.

8. Any neuromodulation that can affect the pelvic organ function.
9. Ongoing, symptomatic Urinary Tract Infection (UTI) at enrolment (defined as a positive urine culture of ≥10\^3 CFU/ml of ≥1 bacterial species and presence of symptoms or signs compatible with UTI with no other identified source of infection).\*
10. Current treatment with anticoagulants (exception acetylsalicylic acid or clopidogrel).
11. Current treatment with long-term systemic steroid medication (exception inhalation agents and/or local topical treatment).
12. Current treatment of prokinetics.
13. Involvement in the planning and conduct of the study (applies to both Wellspect HealthCare and site personnel).
14. Previous enrolment in the present study.
15. Simultaneous participation in another clinical study that may interfere with the present study as judged by the investigator.
16. Expected severe non-compliance to protocol as judged by the investigator.
17. Any other condition, as judged by the investigator, which might make follow-up or investigations inappropriate.
18. Any patient that according to the Declaration of Helsinki is unsuitable for enrolment.
19. Agranulocytosis (\<0.5 10\^9 / L) \[Only applicable for Switzerland\].

    * If symptoms and signs compatible with UTI is present but no urine culture test has been performed yet, a test should be performed, and the result received prior evaluating if the subject is eligible for study participation. After successful and completed treatment of a UTI, the subject may be rescheduled for Visit 1 in order to re-evaluate study participation.
