Study summary

Recurrent cystitis is a common condition in menopausal women and is associated with impaired quality of life and increased antibiotic use. This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy and safety of Colipral® in preventing recurrent cystitis in menopausal women. Participants will be randomized to receive either Colipral® (probiotic strain Escherichia coli 5C (ECP24®)))or placebo for 12 weeks and will be followed for a total of 24 weeks. The study will assess the occurrence of symptomatic cystitis recurrences confirmed by urine culture, as well as symptoms, quality of life, urinary pain, and antibiotic consumption.

Read the detailed description

Recurrent cystitis, defined as two or more episodes within 6 months or three or more episodes within 12 months, is particularly frequent in menopausal women because of age-related changes in estrogen levels, the urogenital epithelium, and the microbiota. The gastrointestinal tract is considered an important reservoir of uropathogenic bacteria, and intestinal dysbiosis may contribute to recurrent urinary tract infections.

This study is a randomized, double-blind, placebo-controlled, parallel-group clinical trial designed to evaluate whether Colipral® (probiotic strain Escherichia coli 5C (ECP24®)) reduces the proportion of menopausal women experiencing recurrent symptomatic cystitis compared with placebo during a 24-week follow-up period. Recurrence is defined as the appearance of urinary symptoms compatible with the need for therapy and confirmed by urine culture.

A total of 134 menopausal women with recurrent cystitis will be enrolled and randomized in a 1:1 ratio to receive either Colipral® or placebo. Participants in the active treatment group will receive one capsule daily for 12 weeks, while participants in the control group will receive an identical placebo for the same duration. The follow-up period will continue beyond treatment discontinuation to evaluate the persistence of the preventive effect.

Secondary objectives include evaluation of the number of cystitis episodes, time to first recurrence, antibiotic consumption, urinary pain assessed by the Visual Analogue Scale (VAS), symptom severity, and quality of life assessed using the UTI-SIQ-8 questionnaire.

Inclusion criteria

  • Menopausal female patients.
  • Age between 55 and 70 years.
  • Diagnosis of recurrent cystitis: ≥2 episodes in 6 months or ≥3 episodes in 12 months, with at least 1 documented episode from urine culture in the last 12 months (if available).

Exclusion criteria

Exclusion Criteria:

  • Complicated urinary tract infections (UTIs) or major complicating factors, including relevant anatomical abnormalities, catheterization, active calculosis, or significant .
  • Hormone replacement therapy (HRT) that has been ongoing or discontinued for less than 6 months.
  • Pyelonephritis within the past 6 months.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Study arms

  • Experimental
    Colipral®

    Participants will receive Colipral® at a dose of 1 capsule per day, administered in the morning or evening, for 12 weeks. The study will evaluate the efficacy and safety of Colipral® in the prevention of recurrent cystitis in menopausal women.

    Dietary Supplement: Colipral®

  • Placebo comparator
    Placebo

    Other: Placebo

Interventions

  • Dietary supplementColipral®

    Colipral® is a probiotic food supplement in gastro-resistant capsules containing the probiotic strain Escherichia coli 5C (ECP24®). Participants will receive one capsule orally once daily, in the morning or evening, for 12 weeks.

  • OtherPlacebo

    Matching placebo identical in shape, color, and packaging to Colipral®, administered orally as one capsule daily in the morning or evening for 12 weeks.

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 Jul 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
