    Proportion of subjects with urges with a mean grade of 3 or 4 per 24h.

    Measured: Prior to Randomization (Baseline) and at Weeks 4, 8, and 12

  15. Urgency (2)

    Change from Baseline in urgency assessments per 24h associated with micturitions and incontinence.

    Measured: Prior to Randomization (Baseline) and at Weeks 4, 8, and 12

  16. Patient Reported Outcomes (1)

    Patient Perception of Bladder Condition

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Solabegron immediate release tablets, low dose and Solabegron immediate release tablets, high dose in people with Overactive Bladder, run by Velicept Therapeutics, Inc. at 86 sites in United States.

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 1 inclusion and 9 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 2 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 86 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Change from Baseline in mean number of micturitions per 24h at Week 12 (time frame: Micturitions will be assessed prior to randomization and at Week 12 (Visit 6).). 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 NCT03475706, 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 2 Mar 2020.
