About this study

Official title: Chronic Bladder Pain Syndrome in Women: Can Doxycycline Help? A Prospective, Randomised,Placebo-controlled, Double-blind Study

Chronic bladder pain syndrome is a chronic disabling disorder characterized by chronic pelvic pain, pressure or discomfort perceived to be related to the urinary bladder accompanied by at least one other urinary symptom such as persistent urgency or frequency in the absence of an identifiable cause. Chronic bladder pain syndrome severely decreases an individual's quality of life and represents a significant financial burden to those affected by it. Currently, multifactorial pathogenesis is assumed including endocrine-involvement, pelvic floor muscle irregularities, immunologic aspects and chemical causes. Corresponding to the wide spectrum of presumptive triggers, a large number of therapeutic approaches are propagated, however most are associated with limited effectiveness. Thus, treatment of BPS is a challenge and the ideal therapy remains to be elucidated. Microorganisms such as Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma genitalium remains a challenge so that these organisms may well be involved in the pathogenesis of chronic bladder pain syndrome. The investigators hypothesise that doxycycline orally for 4 weeks, including therapy of the sexual partner, can significantly relieve symptoms in women with chronic bladder pain syndrome

Background

Doxycycline is used to treat bacterial infections. Doxycycline is in a class of medications called tetracycline antibiotics. In addition to the general indications for all members of the tetracycline antibiotics group, doxycycline is frequently used to treat chronic prostatitis and pelvic inflammatory disease. Especially intracellular agents, such as chlamydia, are generally susceptible to doxycycline. Assuming this infection to be responsible for the chronic bladder pain syndrome in women, therapy will be performed in accordance with the authorised indication and dosage.Bacterial cystitis is an exclusion criterion for the diagnosis of chronic bladder pain syndrome. However, the detection of microorganisms such as Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma genitalium remains a challenge so that these organisms may well be involved in the pathogenesis of chronic bladder pain syndrome. This is supported by the findings of our retrospective study1 that doxycycline orally for 4 weeks including therapy of the sexual partner lead to a reduction of symptoms in 71% of women complaining of persistent urgency and frequency, chronic urethral and/or bladder pain. Therefore, doxycycline therapy is sensible, especially considering that there are only a few, costly and often little effective symptomatic other treatment options.

Thus, we aim to investigate the effectiveness of doxycycline in women with chronic bladder pain syndrome in a prospective, randomised, placebo-controlled, double-blind study.

Chronic bladder pain syndrome is a chronic disabling disorder characterized by chronic pelvic pain, pressure or discomfort perceived to be related to the urinary bladder accompanied by at least one other urinary symptom such as persistent urgency or frequency in the absence of an identifiable cause2. In Europe, prevalence rates in women range from 306 to 450/100'0003,4 - much higher than previously estimated. Thus, chronic bladder pain syndrome is a serious economic problem for every health care system. In addition, chronic bladder pain syndrome severely decreases an individual's quality of life and represents a significant financial burden to those affected by it. Currently, multifactorial pathogenesis is assumed including endocrine-involvement, pelvic floor muscle irregularities, immunologic aspects and chemical causes. Corresponding to the wide spectrum of presumptive triggers, a large number of therapeutic approaches are propagated, however most are associated with limited effectiveness. Thus, treatment of BPS is a challenge and the ideal therapy remains to be elucidated. We hypothesise that doxycycline orally for 4 weeks, including therapy of the sexual partner, can significantly relieve symptoms in women with chronic bladder pain syndrome.

Objective

To proof or reject the effectiveness of doxycycline in treatment of chronic bladder pain syndrome

Methods

This is a prospective, randomised, placebo-controlled double-blind trial. Recruitment of the study participants is performed in the urologic outpatient clinic of University Hospital Inselspital Bern.

The randomisation-list in the institute of pharmacy University Hospital Inselspital Bern will only be accessible to unblinded employees. In case of unblinding an authorized member of the blinded trial team contacts the 24-hours service-number of the pharmacist on-duty in the institute of pharmacy. After disclosure of the patient-number, the pharmacist on-duty performs the unblinding and informs the authorized unblinded trial-member about allocation. Finally unblinding is registered on the randomization list by the pharmacist on-duty.

The unblinded trial-member will record the name of the person who performed unblinding and the date and reason for unblinding in the patient's medical record.

A Phase 4 study testing doxycycline in people with Chronic Pelvic Pain Syndrome and Bladder Pain Syndrome, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 5 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Recruitment problems). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in the O'Leary-Sant IC symptom and problem index total score from baseline (time frame: 4, 8 , 24 weeks). 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 NCT01879930, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Mar 2015.
