简要总结
The study aims to establish the safety and toxicity of a combined intravesical mitomycin C with BCG for patients with bladder cancer.
详细描述
Urine Sample Collection and Handling: Voided urine will be collected pre and post BCG procedure. Urinalysis will be performed if participant presents with urinary symptoms. Analysis of urinary cytokines as predictors of response to therapy will be conducted by ELISA kits.
Tissue Sample Collection and Handling: Tissue biopsy specimens will be collected pre BCG procedure. Analysis of gene expression will be conducted.
TEST PROCEDURES Subjects will be given one of three concentrations of Mitomycin C (MMC) (10 mg in 20 mL, 20 mg in 20 ml or 40 mg in 20 ml) for 30 minutes followed by a 10 minute washout period. Followed by three concentrations of BCG including ¼ strength, ½ strength, and full strength for 2 hours. Dose escalation will take place among subsequent patients and not within each patient.
Approximately 30 subjects will be enrolled to reach the target completion enrollment of 10 subjects.
Long-term Follow-up A Chart review will be conducted every three months for 2 years after initial 6 month study data collection. Patient charts will be reviewed to assess disease progression and any data supporting findings. Long-term follow-up is necessary to determine recurrence rates and long-term safety and efficacy of Mitomycin/BCG treatment therapy as well as BCG therapy in the control group.

研究组 & 干预措施
Therapy Group MMC 10/BCG Half
Intravesical Mitomycin C and intravesical BCG
First intravesical mitomycin C (10 mg) is instilled for 30 minutes. Then the mitomycin is removed and the bladder is gently hand-irrigated with sterile water for 15 minutes in order to facilitate removal of mitomycin C. Then, intravesical BCG (half dose) is instilled for 2 hours under usual conditions. Full dose BCG corresponds to 1 to 8x10^8 colony-forming units of BCG. This study targets patients with BCG-naive or BCG-refractory high-risk non-muscle invasive bladder cancer. The first 3 participants received 10mg of MMC and half dose of BCG. The dose was assigned in order of enrollment.
干预措施: Mitomycin C (Drug)
Therapy Group MMC 10/BCG Full
First intravesical mitomycin C (10 mg) is instilled for 30 minutes. Then the mitomycin is removed and the bladder is gently hand-irrigated with sterile water for 15 minutes in order to facilitate removal of mitomycin C. Then, intravesical BCG (full dose) is instilled for 2 hours under usual conditions. Full dose BCG corresponds to 1 to 8x10^8 colony-forming units of BCG. This study targets patients with BCG-naive or BCG-refractory high-risk non-muscle invasive bladder cancer. The following 3 participants received 10mg of MMC and full dose BCG. Dose was assigned in order of enrollment.
干预措施: Mitomycin C (Drug)
Therapy Group MMC 20/BCG Full
First intravesical mitomycin C (20 mg) is instilled for 30 minutes. Then the mitomycin is removed and the bladder is gently hand-irrigated with sterile water for 15 minutes in order to facilitate removal of mitomycin C. Then, intravesical BCG (full dose) is instilled for 2 hours under usual conditions. Full dose BCG corresponds to 1 to 8x10^8 colony-forming units of BCG. This study targets patients with BCG-naive or BCG-refractory high-risk non-muscle invasive bladder cancer. The next 3 participants enrolled received 20mg of MMC and full dose BCG. Dose was assigned in order of enrollment.
干预措施: Mitomycin C (Drug)
Therapy Group MMC 40/BCG Full
First intravesical mitomycin C (40 mg) is instilled for 30 minutes. Then the mitomycin is removed and the bladder is gently hand-irrigated with sterile water for 15 minutes in order to facilitate removal of mitomycin C. Then, intravesical BCG (full dose) is instilled for 2 hours under usual conditions. Full dose BCG corresponds to 1 to 8x10^8 colony-forming units of BCG. This study targets patients with BCG-naive or BCG-refractory high-risk non-muscle invasive bladder cancer. The last 3 participants received 40mg of MMC and full dose BCG. Dose was assigned in order of enrollment.
干预措施: Mitomycin C (Drug)
结局指标
主要结局
Maximum tolerated dose (MTD)
时间窗: Up to 3 months
The primary objective of this study is to determine the MTD for sequential MMC with BCG and thereby establish a recommended phase 2 dose of the combined therapy.
