Prospective Randomized Comparison of Transurethral Resection by Mean of White Light and Narrow Band Imaging

January 13, 2018 updated by: Paolo Puppo

A Phase III Prospective Multicenter Randomized Comparison of Transurethral Resection by Mean of White Light and Narrow Band Imaging.

To date, fluorescence and narrow band imaging cystoscopy have been tested in many prospective within patient trials but only as an "add on" procedure. This results in a bias that does not allow to determine the real impact of such innovative technologies on bladder cancer management. Hereby we propose the first prospective randomized trial which compares narrow band imaging trans urethral resection as a stand alone procedure versus white light transurethral resection. The primary end point is to assess the recurrence rate of bladder cancer lesions with each treatment modality. The study is designed to disclose an inferior recurrence rate (estimated 10%) in the group treated by narrow band imaging transurethral resection respect to the control group, treated by standard transurethral resection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • All patients must be older than 18 years of age and female patients who are pregnant, breast feeding or not on adequate contraceptive measures will be excluded.
  • All patients will provide a written informed consent prior to the study.
  • Consecutive patients from 2 centers in Liguria (National Institute for Cancer Research - Genova and Centro Urologico di Eccellenza ASL 1 - Imperia) with overt or suspected non muscle invasive bladder cancer, including Cis detected by mean of random biopsies or a positive urinary cytology, will be included in the study and randomized to 2 treatments A, B arms.

Exclusion Criteria:

  • Patients with muscle invasive bladder cancer will be excluded.
  • Patients submitted to immediate radical cystectomy after transurethral resection, irrespective of the clinical stage, will be excluded.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Standard transurethral resection
Patients will be submitted to standard white light transurethral resection and/or cold cup biopsies of all visible lesions known or suspected to be bladder cancer; 6 random cold cup biopsies from healthy mucosa of bladder trigone, anterior, posterior and lateral walls will be taken in case of a second transurethral resection of newly diagnosed high grade non muscle invasive bladder cancer or of recurrent high grade non muscle invasive bladder cancer
Procedure: Standard transurethral resection
Transurethral resection of bladder lesion by mean of standard white light
Experimental: Narrow band imaging transurethral resection
The system will be switched to narrow band imaging by simply pushing a button. Transurethral resection and/or cold cup biopsies of all visible lesions known or suspected to be bladder cancer will be performed; 6 random cold cup biopsies from healthy mucosa of bladder trigone, anterior, posterior and lateral walls will be taken in case of a second transurethral resection of newly diagnosed high grade non muscle invasive bladder cancer or of recurrent high grade non muscle invasive bladder cancer.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Recurrence free survival rate
Time Frame: One year
One year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
