A Multicenter Clinical Trial of Urine DNA Testing for Bladder Cancer in China

Recruiting

• Conditions: Urothelial Carcinoma; Urinary Bladder Stone; Bladder Cancer; Urocystitis
• Interventions: Diagnostic Test: Urine DNA methylation analysis; Procedure: medical imaging and/or cystoscopy and/or pathological examination

• Registration Number: NCT05337189
• Lead Sponsor: Creative Biosciences (Guangzhou) Co., Ltd.

Brief Summary

The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose bladder cancer by comparing with clinical standard method (includes medical imaging (MRI, CT, etc.), cystoscopy, pathological examination).

Detailed Description

In this clinical trial, the testing kit to be evaluated is a Human Multigene Methylation Detection Kit (Fluorescent PCR Method), which is intended to qualitatively detect methylation levels of multiple genes in human urine specimen in vitro by Fluorescent PCR Method, and the standard method used in clinical diagnostic includes medical imaging, cystoscopy, pathological examination.

Subjects will provided urine specimen as required for the evaluation of the testing kit followed by a examination of standard method. Technical personnel who conduct the evaluation of the testing kit will remain blinded to the results of the clinical diagnosis.

The results of the testing kit will be compared with the standard method, and the effectiveness of the Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for bladder cancer detection under normal clinical use will be assessed through statistical analysis.

Primary Outcome Measures

Name	Time	Method
Specificity	One year	Specificity is the percentage of subjects without lung cancer who are correctly excluded by the testing kit.
Consistency Rate	One year	Consistency rate is the fraction of both true positive and negative diagnostic test results among all subjects.
Sensitivity	One year	Sensitivity is the percentage of subjects with lung cancer who are correctly identified by the testing kit.
Kappa Coefficient	One year	Kappa coefficient is the consistency analysis of the extent of agreement between the test results of the testing kit and standard method.
