Summary

This trial will test if BCG and gemcitabine are safe and effective when used together to treat BCG-relapsing bladder cancer.

Who is the study for?

This trial is for adults with high-grade non-muscle invasive bladder cancer that has returned after BCG treatment. Participants must have had all visible tumors removed recently, no upper urinary tract cancer in the last year, and a good performance status. Pregnant individuals, those with BCG contraindications or severe reactions to it, active tuberculosis, immune deficiencies, muscle-invasive or metastatic urothelial carcinoma are excluded.

What is being tested?

The study tests the safety and effectiveness of combining Bacillus Calmette-Guérin (BCG) with increasing doses of Gemcitabine in treating bladder cancer that's come back after BCG therapy. The goal is to find the highest dose of Gemcitabine that works well with BCG and causes few or mild side effects.

What are the potential side effects?

Potential side effects include irritation at the injection site from BCG and typical chemotherapy-related issues from Gemcitabine such as nausea, low blood counts leading to infection risk or bleeding problems, fatigue, fever due to immune response activation by BCG.

Experimental Treatment

Group I: Bacillus Calmette-Guérin (BCG) and GemcitabineExperimental Treatment2 Interventions

Eligible patients will receive combination intravesical chemoimmunotherapy. Treatment is sequential, with twice-weekly intravesical gemcitabine given at weeks 1, 4, 7, and 10, for a total of 8 doses, administered in a standard fashion. In phase I, the dose of gemcitabine will depend on the dose level being assessed for the determination of the MTD. phase II, 1 dose level will be given (the MTD from phase I). Fixed doses of once-weekly intravesical BCG therapy (TICE strain, 50 mg) will be given at weeks 2 (+/- 2 days), 3 (+/- 2 days), 5 (+/- 2 days), 6 (+/- 2 days), 8 (+/- 2 days), and 9 (+/- 2 days), for a total of 6 doses, also administered in a standard fashion. All intravesical therapy will be administered in the chemotherapy suite on an outpatient basis, in accordance with standard clinical practice. Intravesical therapies will be retained in the bladder for up to 2 h (BCG) or 1 h (gemcitabine), or as tolerated.
