Sample Collection for Ongoing Research and Product Evaluation Study - Non-muscle Invasive Bladder Cancer (SCORE-NMIBC)

Prior treatment

• Prior history and treatment for any cancer (including muscle invasive bladder cancer) within the past year, or if they have any other active cancer, with the exception of participants who have undergone surgical removal of basal or squamous skin cancers, as well as those who have received NMIBC-directed therapy, including those undergoing cystectomy for primary NMIBC or after recurrence/progression of NMIBC.
• At time of enrollment, has undergone or plans to undergo any ctDNA or utDNA testing to assess MRD, with the exception of one-time comprehensive genomic profiling for therapeutic drug selection.

Other illness

• Diagnosis of \>T1 bladder cancer at time of enrollment.
• Tumor tissue unavailable and/or consists only of carcinoma in situ (CIS) disease.
• History of bone marrow or organ transplant.
• Serious medical conditions that may adversely affect ability to participate in the study.

Other

• Pregnant or breastfeeding.

• Patient is at least 18 years of age or older.
• Eastern Cooperative Oncology Group performance status ≤ 2.
• Patient has a suspected high risk non-muscle invasive bladder cancer.
  • Note: The AUA/SUO risk stratification for primary non-muscle invasive bladder cancer will be used to determine high risk of tumor progression based on clinic and pathologic prognostic factors (Holzbeierlein et al., 2024):
  • High grade T1.
  • Any recurrent, High-grade TA.
  • High grade TA, \>3 cm (or multifocal).
  • BCG failure in high grade patient.
  • Any variant histology.\*
  • \*e.g. Micropapillary, plasmacytoid, small cell/neuroendocrine, and sarcomatoid histologies (in pure or mixed form with associated urothelial carcinoma)
  • Any lymphovascular invasion.
  • Any high grade prostatic urethral invasion.
• Meet the following criteria:
  • Cohort A: i. Participant has high risk ≤ T1 bladder cancer and is eligible for intravesical therapy or cystectomy. ii. Participant has been treated with intravesical and/or systemic therapy for high risk ≤ T1 bladder cancer and is entering surveillance. b. Cohort B i. Participant has high risk ≤ T1 bladder cancer and undergoing primary treatment with cystectomy. ii. Patients undergoing cystectomy following recurrence or progression of high risk ≤ T1 bladder cancer and where ≤ T1 bladder cancer is confirmed on cystectomy surgical pathology.
• Willing and able to tolerate blood draws according to Natera standard process.
• Willing to provide urine collection samples.
• Able to consent to and provide residual tumor tissue for research.
• Willing and able to comply with the study requirements.
