About this study

Official title: Effects of Single Dose Tadalafil on Urethral and Anal Closure Function and on Urinary Flow in Healthy Females: A Randomised, Controlled, Double-blinded, Two-period Cross-over Study

The purpose of the trial is to assess the effect of tadalafil compared to placebo (inactive comparator) on the urethral - and anal pressure and on urine flow in healthy females. Further, the purpose of the trial is to evaluate the potential for going forward with studies of tadalafil in patients suffering from urine or fecal incontinence.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Placebo-corrected change in opening urethral pressure after single dose tadalafil

    Difference in average urethral opening pressure (UOP) after administration of 40 mg tadalafil (UOP-tadalafil) compared to UOP after placebo (during relaxation).

    Measured: 2 hours post-dose

Secondary outcomes (5)
  1. Difference in average anal opening pressure (AOP) after administration of 40 mg tadalafil compared to AOP after placebo (during relaxation).

    Difference in average anal opening pressure (AOP) after administration of 40 mg tadalafil compared to AOP after placebo (during relaxation).

    Measured: 2-hours post-dose

  2. Difference in average UOP-tadalafil and average UOP-placebo during squeezing.

    Measured: 2-hours post-dose

  3. Difference in average AOP-tadalafil and average AOP-placebo during squeezing.

    Measured: 2-hours post-dose

  4. Elastance (opening/closing) during relaxation and squeezing (tadalafil compared to placebo).

    Measured: 2-hours post-dose

  5. Difference in maximum urine flow rate (Qmax) and average urine flow rate (Qave) after tadalafil and placebo administration, respectively.

    Measured: 2-hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tadalafil 40 MG in people with Urinary Incontinence,Stress and Fecal Incontinence, run by University Hospital Bispebjerg and Frederiksberg at 1 site in Denmark.

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 4 inclusion and 10 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: finished, as of the sponsor's last update on 6 Apr 2022. 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 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Placebo-corrected change in opening urethral pressure after single dose tadalafil (time frame: 2 hours post-dose). 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 NCT05095077, 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 6 Apr 2022.
