About this study

Official title: JPN1: A Confirmatory, Bridging, Double-Blind, Randomized, Controlled Trial in Japan Comparing the Safety and Efficacy of AMDC-USR With Placebo in Female Subjects With Stress Urinary Incontinence

This is a confirmatory/bridging study to evaluate the efficacy and safety of Autologous Muscle Derived Cells for Urinary Sphincter Repair (AMDC-USR) compared with placebo in the treatment of stress urinary incontinence (SUI) in adult Japanese female subjects. Half of the participants will receive AMDC-USR (injections with cells) and the other half will receive placebo.

Read the detailed description

Stress urinary incontinence (SUI) is the accidental loss of urine due to physical activity, such as laughing, coughing, or sneezing. Autologous Muscle Derived Cells for Urinary Sphincter Repair (AMDC-USR) involves a medical procedure in which a participant's own muscle cells are collected, processed, and then injected into the tissues of the urinary passage.

This is a double-blind randomized study, which means neither the participant, nor the study doctor will know which treatment group the participant will be in. Participants who are randomly chosen to receive injection with placebo will have the option to receive an injection with their cells after completion of the blinded portion of their study participation (12 months).

This trial was designed as a confirmatory Phase III study to bridge efficacy and safety data from the Japanese population to the current Phase III global trial for AMDC-USR (CELLBRATE, NCT03104517).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing AMDC-USR in people with Stress Urinary Incontinence, run by Cook MyoSite.

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 3 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The record says: withdrawn, as of the sponsor's last update on 27 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was withdrawn before enrolling participants, so there are no results.

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?

Number of leaks due to stress incontinence episodes, as recorded in a diary. (time frame: 12 months). 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 Aug 2024.
