About this study

The primary objective is to investigate if abrupt withdrawal versus gradual withdrawal of pharmacotherapy (solifenacin and/or mirabegron) influences the risk of recurrence of incontinence.

Children aged 5-14 years diagnosed with urinary incontinence, treated with pharmacotherapy of solifenacin and/or mirabegron and ready for withdrawal will be randomized 1:1 to either abrupt or gradual withdrawal, according to the medical treatment that the child is receiving.

Read the detailed description

Background and rationale: The pharmacological handling of pediatric incontinence is considered temporary and withdrawal attempts are recommended after continence has been achieved. There is no generally accepted withdrawal strategy for solifenacin and/or mirabegron in children. Currently, two different withdrawal strategies are being employed in the clinical setting, namely abrupt withdrawal, and gradual withdrawal, wherein the dosage of the drug prescribed is reduced or the interval between dosages given is increased. Studies report on the differences in withdrawal strategies of antidiuretic therapy targeted at enuresis in pediatric populations. Several studies have reported on the application of structured withdrawal of desmopressin, indicating that gradual withdrawal of desmopressin therapy results in prolonged intervals of continence without relapse. However, to the best of our knowledge, no studies have investigated the strategy of withdrawal of pharmacological treatment with solifenacin and/or mirabegron in children diagnosed with urinary incontinence that have achieved continence on these pharmaceuticals. Our study is proposed to ensure an evidence-based approach to a withdrawal of strategy for pharmacological treatment with solifenacin and/or mirabegron in children with urinary incontinence.

Objectives: The primary objective is to investigate if abrupt withdrawal versus gradual withdrawal of pharmacotherapy (solifenacin and/or mirabegron) influences the risk of recurrence of incontinence. We hypothesize that gradual withdrawal is superior to abrupt withdrawal regarding the risk of recurrence of incontinence.

Study design: This is an open-label prospective randomized trial, allocating participant to each of the three pharmaceutical groups, according to the medical treatment that the child is receiving (solifenacin, mirabegron or solifenacin in combination with mirabegron). Within each pharmaceutical group, the participant will be randomized 1:1 to the intervention being compared; either abrupt withdrawal or gradual withdrawal.

Perspectives:The results are expected to influence the withdrawal strategy of pharmacological treatment with solifenacin and/or mirabegron in children with daytime urinary incontinence.

Ethics: All pharmacological side effects will be handled in accordance with the Danish legislation. No risk or unknown side effects are expected to medical treatment or withdrawal. The therapeutic potential for future patients justifies the project to be carried out. Participation in this study will not lead to any disadvantages for the patient in their treatment. The study will be conducted in accordance with the protocol, applicable regulatory requirements according to Good Clinical Practice and the ethical principles of the Declaration of Helsinki. The study has been approved by the authorities and was initiated in May 2024. Significant additions or changes to the protocol may be conducted after the application for amendment is approved by the Regulatory Authority and the Ethics Committee. Information regarding the participants is protected according to the General Data Protection Regulation and the actual law. The study is registered at the research inventory of the Regions of Denmark (1-16-02-211-24) and at Aarhus University (ARG-2024-731-23833). The study is registered at CTIS (EU CT 2023-510187-13-00).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SolifenacinDrug

    Abrupt withdrawal indicates stopping the medication on the date of withdrawal initiation.

    Gradual withdrawal involves taking the applied dosage of the medication every other day over a period of 14 days, with the complete cessation of the medication occurring 14 days after the gradual withdrawal process begins.

  • MirabegronDrug

    Abrupt withdrawal indicates stopping the medication on the date of withdrawal initiation.

    Gradual withdrawal involves taking the applied dosage of the medication every other day over a period of 14 days, with the complete cessation of the medication occurring 14 days after the gradual withdrawal process begins.

  • Solifenacin + MirabegronDrug

    Abrupt withdrawal indicates stopping the medication on the date of withdrawal initiation.

    Gradual withdrawal involves taking the applied dosage of the medication every other day over a period of 14 days, with the complete cessation of the medication occurring 14 days after the gradual withdrawal process begins.

Secondary outcomes (1)
  1. Development of any symptoms related to abrupt or gradual withdrawal symptoms

    Assessed by a questionnaire on withdrawal symptoms

    Measured: Baseline up to 44 days after initiation of withdrawal

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 7 inclusion and 2 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: under way, not looking for participants, as of the sponsor's last update on 8 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Denmark. 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. 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?

This study is still under way. Results are not available in the source record yet.

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?

Recurrence of incontinence after withdrawal (time frame: Baseline and up to 12 months follow-up). 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 NCT06465576, which also lists 1 linked publication.

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 8 Jun 2026.
