Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

Who may be able to join

  • Subjects must meet the criteria for one of the three following groups:

About this study

Official title: MDSC Clinical Assay for Cancer Detection and Monitoring in Bladder Carcinoma

This pilot research trial studies how well myeloid derived suppressor cells (MDSC) clinical assay works in finding and monitoring cancer cells in blood and urine samples from patients with or without localized or metastatic bladder cancer. Studying samples of blood and urine from patients with or without bladder cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer and may help doctors improve ways to diagnose and treat patients.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate a novel clinical assay (MDSC clinical assay) to detect cancer associated immune cells in the peripheral blood of patients as a means to better detect and monitor malignant bladder cancer in patients.

II. Estimate mean MDSC level, intra-patient variability, and inter-patient variability, for 3 groups of subjects with variable bladder cancer disease status at baseline.

III. In patients with known localized, muscle-invasive bladder cancer who undergo surgical treatment: to determine the change in MDSC level from baseline to after treatment including surgery.

IV. In patients with known metastatic bladder cancer who undergo systemic treatment: to determine the change in MDSC level from baseline to after 4 cycles of treatment compared to the change in tumor burden as evaluated by radiographic imaging.

  1. In patients with no history of cancer: to determine the changes in MDSC levels from baseline to after 4 months.

SECONDARY OBJECTIVES:

  1. Compare MDSC level measurements to urine cytology analysis at baseline and after treatment to determine whether the two tests correlate in any of the 3 groups of patients defined in this study.

OUTLINE:

GROUP I: Patients without cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and 4 months.

GROUP II: Patients with localized bladder cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and within 4 weeks after cystectomy.

GROUP III: Patients with metastatic cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and within 4 weeks after completion of 4 courses of systemic chemotherapy.

What is being measured

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

  1. Change in MDSC level in patients with known localized, muscle-invasive bladder cancer who undergo surgical treatment

    Measured: Baseline to up to 4 months

  2. Change in MDSC level in patients with known metastatic bladder cancer who undergo systemic treatment

    The direction and magnitude of the changes in Group 3 will be compared to the changes in tumor burden assessed radiographically - to explore the associations.

    Measured: Baseline to up to 6 months

  3. Change in MDSC level in patients with no history of cancer

    Measured: Baseline to 4 months

  4. Change in tumor burden evaluated by radiographic imaging

    Measured: Baseline to up to 1 year

Secondary outcomes (1)
  1. Change in urine cytology analysis

    The MDSC levels at baseline will be compared (plots and correlations) to the urine cytology levels (Groups 2 and 3) to describe any associations; for Group 3, the changes (baseline to post treatment) in the MDSC levels will be compared to the changes in urine cytology.

    Measured: Baseline to up to 4 months

Questions about this trial

What is this clinical trial studying?

An observational study of No Evidence of Disease and Stage II Bladder Cancer, run by University of Southern California at 1 site in United States.

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 5 inclusion and 4 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: stopped early, as of the sponsor's last update on 10 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

The study was stopped early (reason given: Insufficient accrual). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in MDSC level in patients with known localized, muscle-invasive bladder cancer who undergo surgical treatment (time frame: Baseline to up to 4 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Aug 2022.
