What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at whether a simple urine test for tumor DNA can tell which bladder cancer patients truly need a second surgery after their first tumor removal. About 196 adults with non-muscle-invasive bladder cancer will be randomly assigned to have their repeat surgery decision guided by the urine test or by standard care. The goal is to avoid unnecessary surgeries and their risks while keeping cancer control safe.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 196 people

The number the study aims to enrol. It can still change while the study runs.

Started

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Participants must meet all of the following criteria to be eligible for the study: 1. Male or female, aged 18 years or older. 2. Histologically confirmed non-muscle-invasive bladder tumor, with no evidence of muscle-invasive bladder cancer or metastatic disease. 3. Histologically confirmed urothelial carcinoma of the bladder or bladder tumor with urothelial carcinoma as the predominant component (\>50%). 4. At least one of the following conditions: 1. Incomplete initial transurethral resection of bladder tumor (TURBT) or suspected incomplete resection. 2. Absence of detrusor muscle in the initial TURBT pathological specimen (except for low-grade Ta stage tumors or carcinoma in situ \[CIS\]). 3. T1 stage tumor. 5. Willingness to provide a 50 mL urine sample between 2-6 weeks after the initial TURBT and prior to re-TURBT. 6. Willingness to provide tumor tissue samples for pathological examination. 7. Willingness to undergo genetic testing required for the trial. Exclusion Criteria: 1. Contraindications to transurethral resection of bladder tumor (TURBT). 2. Concurrent malignancy of the upper urinary tract (ureter or renal pelvis).
