About this study

Official title: Pilot Study to Evaluate the Role for Circulating Tumor DNA (ctDNA) in Monitoring Subjects With Muscle-invasive Bladder Cancer Treated With Trimodality Therapy

The purpose of this prospective biospecimen collection study is to evaluate the feasibility of measuring circulating tumor DNA (ctDNA) in subjects with muscle-invasive bladder cancer (MIBC) treated with trimodality therapy consisting of a maximal transurethral resection of bladder tumor followed by radiation and concomitant chemotherapy.

Cancer cells have unique genes that determine the characteristics of tumors, such as how they will respond to different treatments. The tumor tissue will be used to determine the genes present in cancer cells. Tumor cells sometimes release fragments of DNA into the blood or urine (circulating tumor DNA or ctDNA) and measuring levels of ctDNA may be a way to monitor cancer and predict to determine which treatment works better and what will be the outcome of cancer.

Urine, blood, and tumor tissue are called biospecimens. Biospecimens can help researchers understand how the human body works. Researchers may develop new tests to monitor diseases or new ways to treat diseases. Plasma and urine specimens will be collected before, during, and after the standard-of-care treatment.

This study will estimate the feasibility of collecting plasma ctDNA detection in subjects with MIBC. If this information can be successfully collected and processed, the usefulness of ctDNA to predict tumor response to certain kinds of treatment or disease progression will be evaluated.

What is being measured

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

  1. Feasibility of cell-free plasma ctDNA collection

    The feasibility of cell-free plasma ctDNA collection will be estimated by the percentage of specimens that yield a ctDNA result.

    Measured: Up to 2 years

Secondary outcomes (1)
  1. Feasibility of urine ctDNA collection

    The feasibility of urine ctDNA collection will be estimated by the percentage of specimens that hat yield a ctDNA result.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Bladder Cancer and Muscle-Invasive Bladder Carcinoma, run by UNC Lineberger Comprehensive Cancer Center 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 3 inclusion and 3 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: finished, as of the sponsor's last update on 28 Nov 2025. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Feasibility of cell-free plasma ctDNA collection (time frame: Up to 2 years). 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 28 Nov 2025.
