What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two surgical methods for removing non-muscle invasive bladder tumors. The new method removes the tumor in one piece, while the standard method removes it in fragments. Researchers want to see if the one-piece approach leads to better tumor removal and fewer recurrences. The trial includes 220 patients with tumors between 1 and 6 cm.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
En Bloc resection procedure
What this could lead to
If successful, this surgical technique could lower the chance of bladder cancer coming back and reduce the need for repeat surgeries.
What could go wrong
This is a relatively small, early-stage trial with 220 patients. The procedure may not prove better than standard surgery, and results may not apply to all patients.

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

220 people

The number who actually took part.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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: * Demographics: all BMI, smokers and non-smokers * Primary, papillary, non-solid bladder tumour visualised by flexible cystoscopy * Tumour diameter measured on CT-scan ≥2cm ≤6cm at largest diameter * Ability to fully comprehend the information provided and comply with protocol * Signed consent form * Patients with multiple tumours can be included if it seems feasible to resect them in one procedure Exclusion Criteria: * Clinically suspected muscle invasive bladder cancer (invasion in to bladder muscle or extravesical extension visible on CT or solid tumour without papillary elements seen at cystoscopy) * Tumour located in a bladder diverticulum * Investigating physician concludes that en bloc resection is not technically possible * Pregnancy
