Intravesical Gem/Doce in Patients With NMIBC

Description

Intravesical immunotherapy or chemotherapy for non-muscle invasive bladder cancer (NMIBC) is a well-established treatment for preventing or delaying tumor recurrence after tumor resection. For high-risk non-muscle invasive bladder cancer, immunotherapy in the form of intravesical Bacillus Calmette-Guérin (BCG) can be effective as first-line; nevertheless, the response rate to BCG is suboptimal with many patients failing treatment. Following BCG-failure, however, very few effective therapeutic options exist besides life-changing cystectomy. Recent shortages of BCG have pushed the use of alternative intravesical therapies for non-muscle invasive bladder cancer. At the University of Arizona Cancer Center, the use of intravesical Gemcitabine + Docetaxel (Gem/Doce) is considered as standard treatment for patients with non-invasive bladder cancer who are unable to get BCG or are BCG-resistant. The role of Gemcitabine as first-line treatment for NMIBC is poorly understood. The purpose of this study is to gain a better understanding of the use of Gemcitabine + Docetaxel intravesical chemotherapy for non-muscle invasive bladder cancer.

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Patients able to consent in English or Spanish; provision of signed and dated informed consent form
  • 2. Stated willingness to comply with all study procedures and availability for the duration of the study
  • 3. Male or female ages ≥18 years.
  • 4. Patients with intermediate or high-risk non-muscle-invasive UC of the bladder and no previous BCG treatment.
  • 1. Histologically confirmed intermediate or high-risk non-muscle invasive urothelial carcinoma of the bladder (Ta, T1, or Tis stage) on Transurethral Resection of Bladder Tumor (TURBT) must be obtained within 180 days of registration. OR Patients with a high-grade recurrence after 24 months since last dose of BCG.
  • 6. Eastern Cooperative Oncology Group (ECOG) performance status Grade 0-2. 7. Post-transurethral bladder tumor resection. 8. Evidence of post-menopausal status or negative urinary pregnancy test of female pre-menopausal patients is required. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause.
  • 1. Known hypersensitivity reaction to gemcitabine and/or docetaxel.
  • 2. Clinical T2 or higher stage UC of the bladder.
  • 3. Histopathology demonstrating any small cell component, pure adenocarcinoma, pure squamous cell carcinoma, or pure CIS of the bladder.
  • 4. Active malignancies other than the disease being treated under study.
  • 5. Subjects with concurrent upper urinary tract (i.e. ureter, renal pelvis) urothelial carcinoma of any stage.
  • 6. Pregnant or breast-feeding women.
  • 7. Has an underlying substance abuse or psychiatric disorder such that, in the opinion of the investigator, the patient would be unable to comply with the protocol.
