Sequential Gemcitabine Plus Docetaxel vs Gemcitabine Plus Mitomycin C for BCG-Unresponsive NMIBC
Official title: A Prospective, Randomized, Open-Label, Phase II Trial Comparing Sequential Intravesical Gemcitabine Plus Docetaxel With Sequential Intravesical Gemcitabine Plus Mitomycin C in Patients With BCG-Unresponsive Non-Muscle-Invasive Bladder Cancer
Run by Blokhin's Russian Cancer Research Center · NCT07747740 · Data updated 2026-11-12
This study tests whether adding docetaxel after gemcitabine is better or worse than adding mitomycin C after gemcitabine for people with BCG-unresponsive high-grade non-muscle-invasive bladder cancer.

Is this trial a fit for you?
✓Likely a good fit
Adults with histologically confirmed BCG-unresponsive high-grade NMIBC who have undergone complete TURBT and are candidates for intravesical chemotherapy.
✕Probably not a fit
Patients with muscle-invasive disease, upper tract urothelial carcinoma, or those unable to tolerate intravesical chemotherapy may not benefit from this approach.

What this trial studies
This is a randomized, open-label, phase II trial conducted at a single center. Eligible adults with BCG-unresponsive high-grade NMIBC who have had a complete TURBT are randomized 1:1 to receive either sequential intravesical gemcitabine followed by docetaxel or sequential gemcitabine followed by mitomycin C. Each regimen includes a six-week induction course and twelve months of maintenance instillations, with follow-up assessments including cystoscopy, urine cytology, imaging, adverse events, and quality-of-life questionnaires. The primary endpoint is 12-month event-free survival; secondary endpoints include cystectomy-free survival, progression-free survival, safety, tolerability, and comparative efficacy. The trial plans to enroll 228 participants to evaluate bladder-preserving strategies in this high-risk population.
Why it matters
Potential benefit: If successful, the regimen could offer a bladder-preserving treatment option with favorable event-free and progression-free outcomes for patients who cannot or will not undergo radical cystectomy.
How similar studies have gone: Prior data suggest intravesical chemotherapy can preserve the bladder, and sequential regimens have shown promise, but this specific gemcitabine-docetaxel versus gemcitabine-mitomycin C comparison is novel in this setting.

Complete transurethral resection of bladder tumor (TURBT) before study treatment. 4. Intermediate- or high-risk NMIBC according to current clinical guidelines. 5. Candidate for intravesical chemotherapy. 6. ECOG performance status 0-2. 7. Adequate hematologic, renal, and hepatic function. 8. Written informed consent. Exclusion Criteria: 1. Muscle-invasive (≥T2), locally advanced, or metastatic urothelial carcinoma. 2. Upper urinary tract urothelial carcinoma requiring treatment. 3. Previous hypersensitivity to gemcitabine, docetaxel, mitomycin C, or formulation components. 4. Active uncontrolled urinary tract infection. 5. Pregnancy or breastfeeding. 6. Concurrent participation in another interventional clinical trial. 7. Any serious uncontrolled medical condition that, in the investigator's opinion, would interfere with study participation or interpretation of results.
