Detection of FGFR Gene Mutations in the Tumor Tissue and Urine of Patients With Urothelial Carcinoma

April 6, 2022 updated by: Ho Kyung Seo
This study aims to compare the correlation between FGFR mutations found in bladder cancer tissues and urine to develop a companion diagnostic method for predicting the effect of FGFR inhibitors using urine samples of the patients with urothelial cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

This study targets 92 patients with urothelial cancer, whose tissue (from scheduled surgery) and urine samples can be obtained, regardless of the treatment stage.

■ Examination Methods

  • FGFR mutations in bladder cancer tissues will be analyzed using next-generation sequencing and current companion diagnostic methods.
  • FGFR mutations in urine samples obtained from patients with bladder cancer will be analyzed using nanowires.
  • Bladder cancer subtyping will be performed by RNA sequencing of tumor tissues or other methods.
  • Analysis of paired tissues before and after chemotherapy will be performed on transurethral resection of bladder tumor (TUR-BT) and cystectomy tissues before and after neoadjuvant chemotherapy.

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

20 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Suspected patients of urothelial cancer who will visit the National Cancer Center Korea.

Description

Inclusion Criteria:

  • Suspected patients of urothelial cancer who will visit the National Cancer Center Korea from the date of Institutional Review Board (IRB) approval to 2021 and with identified tumors in the bladder according to bladder endoscopy.
  • Subjects who are scheduled for surgery (transurethral bladder tumor resection, radical bladder resection, and radical bladder ureterectomy) and have agreed to participate in the study

Exclusion Criteria:

  • History of other active malignant tumors treated within 24 months
  • Patients with either mental illness or who cannot participate in clinical trials at the judgment of other doctors
  • If patients and guardians do not want to participate in this study
  • History of having administered FGFR inhibitors in the past

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
Measure Description
Time Frame
Correlation between FGFR mutations found in bladder cancer tissues and urine before and after treatment
Time Frame: Up to two weeks before and after surgery
The ratio of patients with matching test results to total patients
Up to two weeks before and after surgery

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.
Outcome Measure
Measure Description
Time Frame
Changes in FGFR mutations in tissues before and after treatment
Time Frame: Up to two weeks before and after treatment
Changes in FGFR mutations in tissues before and after treatment will be observed in the patients with muscle-invasive and non-muscle-invasive bladder cancer undergoing neoadjuvant chemotherapy and transurethral bladder tumor resection, respectively, due to recurrence.
Up to two weeks before and after treatment
Patient prognosis
Time Frame: six months and one year after treatment
recurrence-free
six months and one year after treatment
Patient prognosis
