TEST:

Bladder EpiCheck®

Conclusions BE could allow a reduction in the number of cystoscopies in the follow-up of HR-NMIBC, with a potential improvement in the quality of life of patients, given its high NPV. Management of a positive BE must be individualized for each patient, with a high Se for non-LG recurrence in HR-NMIBC patient.

The combination of BE and urinary cytology correctly identified 29 out of 30 carcinomas, while 289 were correctly diagnosed as negative results. The combination of BE and cytology could be the most effective approach for follow-up diagnosis in patients with high-grade NMIBC, reducing unnecessary invasive procedures.

Bladder Epicheck® is a useful urinary marker in the follow-up of NMIBC, with significantly high Se and NPV in the detection of recurrences, especially in cases of HG disease. Its use can reduce the number of cystoscopies required in the follow-up of NMIBC, improving the quality of life of patients and potentially increasing health economic savings.

"Nucleix...announced that the results from the company's North American pivotal clinical study evaluating the performance of Bladder EpiCheck® as a non-invasive and objective novel methylation-based PCR urine test for the surveillance of non-muscle invasive bladder cancer (NMIBC) recurrence were presented in a podium presentation at the American Urological Association (AUA) Annual Meeting 2024 in San Antonio, Texas. The data presented demonstrated Bladder EpiCheck’s potential to improve timely disease recurrence detection and compliance with NMIBC surveillance."

P=N/A; Overall trial duration is estimated at 5 yr from when the study opens to enrollment until completion of data analyses. The trial is registered at clinicaltrials.gov (NCT05796375).

Due to its high sensitivity for HG tumors, the Bladder Epicheck® Test can be used in diagnosis and treatment decision-making of UTUC. Furthermore, it could be very useful in follow-up of UTUC, after endoscopic treatment to postpone or avoid unnecessary endoscopic exploration. Even if further studies are needed to validate these findings, Bladder Epicheck® could be a promising clinical tool for detection of UTUC.

BE performance could improve timely disease recurrence detection and compliance with NMIBC surveillance. BE's high HG NPV supports the use as a rule-out test for HG disease. With high specificity and PPV, BE's false positive rates are low, potentially minimizing unnecessary downstream procedures and patient anxiety.

"Based on the results of this simulation, a marker-supported follow-up of patients with HR NMIBC is safe and offers the option to significantly reduce the number of WLCs. Further research focusing on prospective randomized trials is needed to finally find a way to implement urine markers into clinical decision-making."

In the follow-up for NMIBC, for patients for whom a BE test is planned, a combined approach of cytology and a methylation test is recommended in order to repeat the BE test with an invalid result only in those cases with a cytological diagnosis of atypical urothelial cells (AUC) suspicious for high-grade urothelial carcinoma (SHGUC) and high-grade urothelial carcinoma (HGUC).

Bladder EpiCheck demonstrated excellent and consistent performance for NMIBC surveillance across pivotal and independent studies performed in various populations and labs. The high HG NPV supports the use of Bladder EpiCheck as a rule-out test for HG disease. With a high specificity and PPV, Bladder Epicheck's false positive rates are low, potentially minimizing unnecessary downstream procedures and patient anxiety.

"Nucleix...announced it has been informed it will receive national reimbursement approval from The Dutch Healthcare Authority (NZA) in the Netherlands, effective January 1, 2024, for its CE-marked Bladder EpiCheck^® test for detection of primary or recurrent bladder cancer and upper tract urinary cancer."

"Nucleix...announced participation in the Association Francaise d'Urologie (AFU) Registry of the Therapeutic Management and Follow-Up of Non-Muscle-Invasive Bladder Cancer (TVNIM-AFU). The registry will evaluate the diagnostic performance of selected urine biomarkers in French patients and compare them to the results of bladder endoscopies (cystoscopy) performed over two years for routine follow-up of NMIBC. The registry is open to all urologists who are members of the AFU to include patients undergoing tumor resection."

This review assesses the importance of methylation analysis and the Bladder EpiCheck test as urinary biomarkers for diagnosing urothelial carcinomas in patients in follow-up for NMIBC, helping cytology and cystoscopy in doubtful cases. A combined approach of cytology and methylation analysis is suggested not only to diagnose HGUC, but also to predict clinical and histological recurrences.

"Nucleix...has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market Bladder EpiCheck® for use as a non-invasive method for surveillance of tumor recurrence in patients previously diagnosed with non-muscle invasive bladder cancer (NMIBC), in conjunction with cystoscopy....Bladder EpiCheck is a highly sensitive and specific test that analyzes subtle disease-specific changes across 15 methylation markers that are associated with bladder cancer. The test is commercially available in Europe and is the first of its kind methylation-based urine test performed on a qPCR platform to be cleared by the FDA....Nucleix is evaluating strategic partnerships and other market access activities for the commercial launch of Bladder EpiCheck in the United States."

The Bladder EpiCheck test has a better sensitivity than urine cytology and may be utilized as a part of the active surveillance strategy for NIMBC recurrence.

"Bladder-Epicheck® and Urovysion®FISH along with cytology could be a helpful ancillary method in the diagnosis and follow-up of UTUC while due to its low specificity Xpert®-BC Detection seems to be of limited usefulness."

To the best of the authors' knowledge, this is the first study in which patients at high risk for HGUC were stratified using the Bladder EpiCheck EpiScore. The results validate this methylation analysis tool as a useful method for predicting recurrent HGUC during the follow-up of patients with nonmuscle-invasive bladder carcinoma.

To conclude, the BE can be used to reduce the costs of NMIBC follow-up, with a small delay in diagnosis of recurrent disease.

The EpiCheck (test showed very high diagnostic values, higher than the currently, gold standard. The test might clinically improve the BCa management in terms of, reduced number of inconclusive/suspicious reports of cytology and endoscopy, reduced number of further examinations, reduced associated patient and economic.

We demonstrated the usefulness of a DNA methylation test in the follow-up of patients diagnosed with urothelial carcinoma. The methylation test also helps to diagnose urothelial cell atypia.

"Nucleix...announced that the company has expanded the European Union (EU) label indication of its Bladder EpiCheck® test. Bladder EpiCheck detects DNA methylation patterns in urine that are associated with urothelial cancer....The current update expands the label indication to also include aiding in the detection of primary bladder cancer and upper tract urothelial carcinoma (UTUC) in patients presenting with hematuria and/or other urinary tract symptoms and/or findings with a suspicion of malignancy, and the detection of recurrent UTUC, in conjunction with standard diagnostic procedures."

Epicheck may be an important tool to decrease number of unnecessary URS. The clinical implementation of EpiCheck in UTUC warrants further investigation in multicentric prospective randomized trials.

The AUC was 81%(95%CI:73-89) for AG BC, and 96%(95%CI:88-100) for HG BC. Conclusions : BE showed high diagnostic performance in HG BC.

"Nucleix...announced its Bladder EpiCheck® test has been included in the 2022 European Association of Urology (EAU) Clinical Guidelines for non-muscle invasive bladder cancer (NMIBC)...The EAU guidelines state that urinary biomarker tests with high sensitivity and negative predictive values for high-grade disease, including a specific reference to Bladder EpiCheck, might be used to replace and/or postpone cystoscopies in low- and intermediate-risk NMIBC, and reduce the number of cystoscopies in this patient population."

BE is a very accurate diagnostic tool that has the potential to be useful in the surveillance of high-risk BC patients. Especially when combined with UC, it may be used to reduce the number of cystoscopies needed throughout follow-up. Conversely, the use of PDD as a diagnostic tool in such patients should be reconsidered. However, due to the small sample size of this study, a larger prospective clinical trial should be performed to confirm findings.

In the early follow-up of NMIBC the EpiCheck test might replace urinary cytology.

There is not enough data to reliably assess their use in the primary diagnostic setting. These results have to be confirmed in larger cohort as well as in head-to-head comparative studies.

"Our analyses support high diagnostic accuracy of the studied novel UBTs, supporting their utility in the NMIBC surveillance setting. All of these might potentially help prevent unnecessary cystoscopies safely. There are not enough data to reliably assess their use in the primary diagnostic setting. These results have to be confirmed in a larger cohort as well as in head-to-head comparative studies. Nevertheless, our study might help policymakers and stakeholders evaluate the clinical and social impact of the implementation of these tests into daily practice."
