Trial summary

Voided urinary cytology (VUC) is the most widely used urine-based assay for detecting bladder cancer (BCa); however, it fails to detect approximately 50% of low-grade or early stage BCa when it is most curable. Furthermore, the detection rate of VUC for recurrent BCa is not much better. Read more about this study

About this study

Voided urinary cytology (VUC) is the most widely used urine-based assay for detecting bladder cancer (BCa); however, it fails to detect approximately 50% of low-grade or early stage BCa when it is most curable. Furthermore, the detection rate of VUC for recurrent BCa is not much better. Because of this severe limitation, all patients who are under surveillance to monitor for recurrent BCa must undergo an invasive examination of the urinary bladder, where a miniature camera is inserted into the bladder and the bladder inspected (cystoscopy). We propose to improve the non-invasive detection of recurrent BCa by further validating a multiplex ELISA assay directed at a BCa-associated diagnostic signature in voided urine samples.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity and specificity of multiplex ELISA assay will be confirmed by cystoscopy.

    To examine the sensitivity and specificity of the multiplex ELISA assay directed at a BCa-associated diagnostic signature in voided urine samples to reference standard of cystoscopy in a prospective longitudinal cohort of 300 participants with a history of BCa currently on cancer surveillance.

    Measured: 2 years

Secondary outcomes (1)
  1. Sensitivity and specificity of multiplex ELISA assay will be compared to VUC and NMP22 BladderCheck.

    To compare the sensitivity and specificity of the multiplex ELISA assay to VUC and NMP22® BladderChek to reference standard of cystoscopy in this cohort.

    To develop a BCa risk calculator from this cohort using cutting edge machine learning techniques (e.g., random forest) incorporating biomarker data and clinical data.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Bladder Cancer, run by Cedars-Sinai Medical Center at 4 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 4 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Charles Rosser, MD (310-423-5609, Charles.Rosser@cshs.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity and specificity of multiplex ELISA assay will be confirmed by cystoscopy. (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03193515, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2026.
