About this study

Official title: Comparison of the Efficacy of Solifenacin With or Without Tamsulosin in Adult Women With OAB: A Prospective Randomized Multicenter Study

The aim of the study is to investigate if the combination therapy consisting of anticholinergics plus alpha-blockers could be beneficial for women suffering from Overactive Bladder (OAB).

Read the detailed description

Overactive bladder (OAB) describes the symptom complex of urgency, with or without urge incontinence, usually with frequency and nocturia.

The lower urinary tract is innervated by both the parasympathetic and the sympathetic nervous system, that act via muscarinic and adrenergic receptors, respectively.

Antimuscarinics are mainly used for the treatment of patients with OAB, especially women. Other than antimuscarinics, a1-blockers have been shown in several clinical reports to be useful in treating DO caused by neurological diseases.

What is being measured

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

  1. Change in Mean Number of Micturition Episodes Per 24 Hours

    Measured: at week 24 relative to baseline

Secondary outcomes (5)
  1. Numeric Change of Urgency Episodes Per 24 Hours

    Measured: at week 24 relative to baseline

  2. Change in Total Score of OABSS

    Total Score of OABSS(Overactive Bladder Symptom Score) is the sum of 4 questions, ranging from 0 (best possible outcome) to 15 (worst possible outcome)

    Measured: at week 24 relative to baseline

  3. Change in Score of IPSS

    Total Score of IPSS(International Prostate Symptom Score) is the sum of 7 questions, ranging from 0 (best possible outcome) to 35 (worst possible outcome). The 7 symptom questions include feeling of incomplete bladder emptying, frequency, intermittency, urgency, weak stream, straining and nocturia, each referring to during the last month, and each involving assignment of a score from 0 to 5 for a total of maximum 35 points.

    Measured: at week 24 relative to baseline

  4. Change of PVR

    Change from baseline in Post-Void Residual (PVR) volume

    Measured: at week 24 relative to baseline

  5. Change of Qmax

    maximal urinary flow rate (Qmax) assessed by uroflowmetry

    Measured: at week 24 relative to baseline

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Solifenacin and Solifenacin plus Tamsulosin in people with Overactive Bladder, run by Soonchunhyang University Hospital at 1 site in South Korea.

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 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: finished, as of the sponsor's last update on 27 Jan 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 South Korea. 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?

Yes. Results are posted in the registry (first posted 27 Jan 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Mean Number of Micturition Episodes Per 24 Hours (time frame: at week 24 relative to baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 27 Jan 2015.
