Bladder cancer patients may skip surgery with new drug combo
NCT ID NCT05644041
First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 2 times
Summary
This study tests a combination of two chemotherapy drugs (gemcitabine and docetaxel) given directly into the bladder for people with non-muscle invasive bladder cancer. The goal is to see if this treatment can control or eliminate tumors, especially for those who cannot get standard therapy or have not responded to it. About 25 adults with intermediate- or high-risk bladder cancer will participate, and the main focus is on how many have no cancer detectable after 3 months.

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.

Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. Exclusion Criteria: 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.
