Initial Evaluation of a Telomerase-based Circulating Tumor Cell Assay in Bladder Cancer Cohorts

December 8, 2020 updated by: Abramson Cancer Center of the University of Pennsylvania
Purposes are to determine whether various cohorts of bladder cancer patients have detectable tCTC's, determine it tCTC levels vary with the natural history of bladder cancer and to see if tCTC's provide novel information.Study population are various cohorts of patients diangosed with urothelial carcinoma of the bladder.Procedures include a venous blood draw, up to two times, over a 6 month period for collection of tCTC's. Up to 15 mL's of blood will be collected at each blood draw.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Urothelial Carcinoma of the Bladder

Description

Inclusion Criteria:

  • a.Urothelial carcinoma or mixed urothelial carcinoma arising from the bladder
  • b.Age 18 or older
  • Inclusions by cohort Cohort 1. Patients with localized muscle-invasive disease (cT1,cN0, M0) at the time of initial diagnosis or who have progressed from superficial disease (cT2) who have not had any systemic chemotherapy and who will be treated with upfront radical cystectomy. PriorTURBT and intravesical therapies are allowed but should not have been done within one week of CTC measurement. If the patient is found to have no evidence of tumor (pT0) upon evaluation of the cystectomy specimen, the patient will not be dropped. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 1 and included in Cohort 9 instead.
  • Cohort 2. Patients with localized muscle-invasive disease (cT1, cN0, M0) at the time of initial diagnosis prior to definitivechemo-radiation. Prior TURBT and intravesical therapies are allowed but should not have been done within one week of CTC measurement. If the patient is found to have evidence of progression by anyclinical evaluation performed within 2 months of the post-treatment sample, the patient will be droppedfrom Cohort 2 and included in Cohort 9 instead.
  • Cohort 3. Patients with localized muscle-invasive disease (cT1, cN0, M0) at the time of initial diagnosis or who have progressed from superficial disease (cT2) who have not had any systemic chemotherapy and who will be treated with neoadjuvant chemotherapy. Prior TURBT and intravesical therapies are allowed but should not have been done within one week of CTC measurement. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 3 and included in Cohort 9 instead.
  • Cohort 4. Patients with metastatic disease (anyT, anyN, M1) at initial presentation or recurrent after definitive treatment prior to any salvage systemic chemotherapy. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 4 and included in Cohort 9 instead.
  • Cohort 5. Patients with newly diagnosed non-muscle-invasive bladder cancer (T2) prior to any intravesical therapy. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped.
  • Cohort 6. Patients with muscle-invasive bladder cancer after radical cystectomy with or without peri-operative systemic chemotherapy (pT2, anyN, M0) who will be treated with adjuvant radiation. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 6 and includedin Cohort 9 instead.
  • Cohort 7. Patients with a history of muscle invasive bladder cancer (cT1, any N,M0) who have no evidence of disease at least 2 years after the date of radical cystectomy. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 7 but may be considered for inclusion in Cohort 4.
  • Cohort 8. Patients with a history of muscle invasive bladder cancer (cT1, any N, M0) who have no evidence of disease at least 2 years after the completion of definitive chemo-radiation. If the patient is found to have evidence of progression by any clinical evaluation performed within 2 months of the post-treatment sample, the patient will be dropped from Cohort 8 but may be considered for inclusion in Cohort 4.
  • Cohort 9. Patients who were initially included in Cohorts 1-6 but were found to have progression at the time of their post-treatment blood draw. Of note, patients may be included in more than one cohort over time so long as inclusion and exclusion criteria are met. In addition, twenty samples from normal controls without any history of malignancy will be used for this study but havealready been collected as part of a separate protocol.

Exclusion Criteria:

  • pure squamous or pure adenocarcinoma bladder cancer histology. This exclusion may be waved at the discretion of the protocol PI. 2. Prior cancer diagnosed within 3 years of enrollment other than a prior bladder, prostate, or skin cancer. This exclusion may be waved at the discretion of the protocol PI.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
