About this study

Official title: A Phase 2, Randomized, Double-blind, Placebo-controlled, Parallel Group, Adaptive, Combined Proof of Concept and Dose-Finding Study to Investigate Efficacy, Safety, Pharmacodynamics and Pharmacokinetics of ASP3652 in the Treatment of Female Patients With Bladder Pain Syndrome / Interstitial Cystitis

In this study several dose levels of ASP3652, given orally for 12 weeks, will be compared with placebo in the treatment of female patients with Bladder Pain Syndrome / Interstitial Cystitis.

Read the detailed description

This study consists of a screening phase, an initial 3 weeks Run-in period,

a 12 weeks Treatment period and a 2 weeks Follow-up (FU) period.

This study will investigate the efficacy and safety of a 12 week treatment with ASP3652 in female patients with Bladder Pain Syndrome / Interstitial Cystitis (BPS/IC). Different dose levels of ASP3652 will be compared with placebo. ASP3652 is administered as oral tablets. The objectives of the study are to investigate efficacy of ASP3652 in patients with BPS/IC, to assess the optimal dose of ASP3652, to investigate safety and tolerability and to investigate pharmacokinetics and pharmacodynamics of ASP3652 in patients with BPS/IC in an out-patient setting.

    Measured: Baseline, 4, 8, 12 weeks treatment and 2 weeks follow-up post treatment

  8. Proportion of responders: at least 7-point decrease in F-GUPI Total score at 0, 4, 8 and 12 weeks treatment compared to baseline

    Measured: Baseline, 4, 8 and 12 weeks treatment

  9. Assessment of pharmacokinetics at week 4, 8 and 12

    Plasma levels of anandamides

    Measured: 4, 8 and 12 weeks treatment

  11. Safety as assessed by recording Adverse Events, Laboratory tests, electrocardiograms (ECGs) and vital signs

    Measured: Baseline and 12 weeks treatment

  12. Safety as assessed by SteatoTest, adiponectin and PVR

    Measured: Baseline and 12 weeks

  13. Change from baseline in questionnaires (Center for Epidemiologic Studies Depression Scale and Profile of Mood States questionnaire) at 12 weeks treatment

    Measured: Baseline and 12 weeks treatment

  14. Physician Withdrawal Checklist at 12 weeks treatment and at 2 weeks follow-up post treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ASP3652 in people with Cystitis, Interstitial and Urinary Bladder Disease, run by Astellas Pharma Europe B.V. at 60 sites in 12 countries.

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 15 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 5 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 60 sites in Poland, Germany, Romania, Czechia, Russia and 7 more countries. 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 Daily Pain (MDP) at 12 weeks (time frame: Baseline and 12 weeks). 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 5 Nov 2024.
