A sample of the Overactive Bladder Pipeline Review: the full chapter list, the tracker columns and two asset profiles from the report. The Research Desk reviews your request and emails it, usually within one business day.

Overactive Bladder has 6 drug candidates in active clinical development, of which 1 are in Phase III, 4 in Phase II and 1 in Phase I, according to Douglas Insights' count of 154 interventional trials registered on ClinicalTrials.gov (data as of 4 Oct 2026).

The overactive bladder drug pipeline is the set of medicines that sponsors are still testing in people for this condition: each candidate is counted once, at the highest phase it has reached in a running or recently completed trial. Medicines already on the market and studied only in Phase IV trials are kept out of the count.

How many overactive bladder drugs are in each phase of development?

Douglas Insights counts 1 overactive bladder candidates in Phase III, 17% of the 6 assets in development; Phase II holds 4 and Phase I holds 1.

Phase I1Phase II4Phase III1

Phase I/II candidates sit in the Phase I row and Phase II/III candidates in the Phase II row, so each overactive bladder asset appears in exactly one row. The 36 trials still recruiting or running carry 23% of the 154 registered trials in scope.

Which approved overactive bladder medicines are still in trials?

3 medicines already on the market are still being tested in overactive bladder Phase IV trials; Mirabegron has the most, with 46 registered trials.

Post-approval overactive bladder trials test new doses, new patient groups and head-to-head comparisons. They set the standard of care that every candidate in development will be measured against, so the paid review profiles each one.

How many overactive bladder trials are recruiting patients now?

23 overactive bladder trials are recruiting patients and 10 more have not started recruiting yet, out of 154 interventional trials in scope; together they make up 21% of the trial base.

Registry statusTrialsShare
Completed8455%

Status not verified1812%
Terminated117.1%
Not yet recruiting106.5%
Withdrawn53.2%
Active, not recruiting21.3%
Enrolling by invitation10.6%

Terminated, suspended and withdrawn overactive bladder trials stay in the trial base so that a stalled programme is visible, but a candidate whose only trials stopped is no longer counted as in development.

Which companies lead the overactive bladder pipeline?

Cyllene Therapeutics leads the overactive bladder pipeline with 1 candidates; the top 5 sponsors hold 83% of the 6 assets, and 6 sponsors run at least one.

SponsorAssets in developmentShare
Cyllene Therapeutics117%
Sarfez Pharmaceuticals, Inc.117%
Allergan117%
Vensica Therapeutics Ltd.117%
AbbVie117%

Industry sponsors lead 57 of the 154 overactive bladder trials (37%); universities, hospitals and public funders lead the rest. A sponsor is credited with an asset when it is the lead sponsor on most of that asset's industry trials.

Which drug types and mechanisms dominate the overactive bladder pipeline?

Mechanism and drug-type classification for the 6 overactive bladder candidates is done by the research desk asset by asset, each with a cited source, and is published in the paid review together with the white-space map.

What overactive bladder trial readouts are coming next?

2 overactive bladder candidates in Phase II or later have a registered primary completion date in the next 12 months; the next three are below, each linked to its registry record.

Primary completion is the date a sponsor expects the last patient to finish the main measurement, so data usually follow within months. Dates marked estimated are the sponsor's own forecast on the registry and often move.

How many overactive bladder readouts fall in each quarter?

3 overactive bladder candidates in Phase II or later reach registered primary completion over the next eight quarters, with the most, 1, due in Q4 2026.

Each candidate is counted once, at its next readout. The paid catalyst calendar names every readout with its trial, sponsor and design, adds filings and regulatory decisions, and runs 24 months ahead.

Which countries host the most overactive bladder trials?

United States hosts the most overactive bladder trials, with sites in 66 of the 154 studies (43%); trials in scope run in 61 countries in all.

Poland1912%
Canada1812%
Belgium1812%
Denmark1610%
Germany159.7%
Norway159.7%

A multinational overactive bladder trial is counted once in every country where it has a site, so the shares add up to more than 100%. Country spread shows where sponsors are building the evidence that regulators in each market will ask for.

Where are overactive bladder drugs being tested?

66 of the 154 overactive bladder trials (43%) have a site in the United States, 36 (23%) in Europe and 9 (5.8%) in China; 5 of the 6 candidates in development are tested in the US.

Europe (EU/EEA, UK, Switzerland)3623%1EMA, MHRA, Swissmedic
China95.8%0NMPA
Japan74.5%0PMDA
Rest of world6744%3national regulators

Each region's trials are the evidence its regulator will review: the FDA in the United States, the EMA (with the MHRA and Swissmedic) in Europe, the NMPA in China and the PMDA in Japan. A multinational overactive bladder trial counts once in every region where it has a site, so the shares add up to more than 100%. A candidate tested only outside the US and Europe is often a licensing opportunity for sponsors in those markets.

What has changed in the overactive bladder pipeline since the last update?

This is the first edition of the overactive bladder pipeline count, dated 4 Oct 2026. The next refresh is due by 2 Jan 2027, and each refresh lists the assets that entered, advanced or dropped out.

How does Douglas Insights count the overactive bladder pipeline?

Douglas Insights read 154 interventional trials registered on ClinicalTrials.gov for the conditions "Urinary Bladder, Overactive", "overactive bladder" and updated since 4 Oct 2021, then grouped every drug or biologic named in them into 6 unique candidates.

  1. Code names, generic names and brand names of the same molecule are merged into one candidate, and every merge is reviewed by the research desk.
  2. A candidate counts when it has a trial that is recruiting, running, or completed in the last 24 months, and at least one industry-sponsored trial.
  3. Its phase is the highest phase among those trials; placebo, standard-of-care and comparator arms are not candidates.
  4. Each figure on this page is drawn from one frozen dataset that passes ten checks before release, and the owner approves every edition.
