PENK Methylation Test for Detecting Bladder Cancer

Recruiting

• Conditions: Hematuria; Benign; Bladder Cancer
• Interventions: Diagnostic Test: EarlyTect® Bladder Cancer test

• Registration Number: NCT05220189
• Lead Sponsor: Asan Medical Center

Brief Summary

The primary objective of this clinical trial is to determine the sensitivity and specificity of the EarlyTect® Bladder Cancer test for bladder cancer among patients with hematuria by comparing it to the results of cystoscopy examinations.

The second objective is to compare the clinical performance of EarlyTect® Bladder Cancer test with a NMP22 test and urine cytology test with respect to bladder cancer. By histopathological examination, lesions identified during cystoscopy will be confirmed as malignant or non-malignant by histological examination.

Detailed Description

Patients with hematuria who are scheduled for cystoscopy will be asked to collect a urine sample for EarlyTect® Bladder Cancer test and will undergo NMP22 and urine cytology tests. The participants will undergo a cystoscopy within 30 days of enrollment. For confirmation of the diagnosis and stage of the tumor, representative histopathology slides from TURBT (Transurethral Resection of Bladder Tumors) may be retrieved and examined by the central pathology laboratory.

Arm && Interventions

Group	Intervention	Description
Hematuria patients aged ≥40	EarlyTect® Bladder Cancer test	Device: EarlyTect Bladder Cancer test, PENK methylation assay by LTE (Linear Target Enrichment)-qMSP (quantitative methylation-specific real time PCR)

Primary Outcome Measures

Name	Time	Method
Sensitivity and specificity of the EarlyTect® Bladder Cancer test	1 year	Sensitivity and specificity of the EarlyTect® Bladder Cancer test for detecting bladder cancer (Stages Ta high-grade and T1-T4) in patients with hematuria compared to the cystoscopy examination, both in terms of detecting bladder cancer. The reference method is the cystoscopic procedure, and lesions will be assessed histopathologically.; EarlyTect® Bladder Cancer test includes a measurement of PENK methylation and COL2A1 as a DNA control.; PENK methylation in urine DNA will be assessed quantitatively by Linear Target Enrichment-coupled Quantitative Methylation-Specific PCR (LTE-qMSP) using the Real-time PCR method. The results will be dichotomized by the CT (cycle threshold) cutoff value as either positive or negative. Sensitivity = 100\*(positive PENK methylation test/positive cystoscopy), Specificity = 100\*(negative PENK methylation test/negative cystoscopy).

Secondary Outcome Measures

Name	Time	Method
The performance of the EarlyTect® Bladder Cancer test	1 year	The performance of the EarlyTect® Bladder Cancer test in detecting Bladder cancer in hematuria patients will be compared with those of the NMP22 and urine cytology tests.
