Summary

Research topic: A randomized, double-blind, active-controlled, multicenter phase III clinical trial evaluating the efficacy and safety of therapeutic BCG for the prevention of postoperative recurrence of non-muscle-invasive bladder cancer in people aged 18 years and older. The name of the drug: Bacillus Calmette-Guérin for treatment(BCG). Clinical indications: It is used for the treatment of bladder carcinoma in situ and the prevention of recurrence, and for the prevention of recurrence of bladder papilloma after transurethral resection in Ta or T1 stage. This product is not used for papillomas beyond the T1 stage. Study population: Patients aged 18 years and above with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC) who have undergone transurethral bladder tumor resection. Objectives: Primary Objectives: To assess the effectiveness of BCG for therapeutic use in the adjuvant treatment of intermediate- and high-risk NMIBC after transurethral resection of bladder tumors. Secondary Purpose: To assess the safety of the therapeutic BCG vaccine in the adjuvant treatment of intermediate- and high-risk NMIBC after transurethral resection of bladder tumors. Other purposes: To assess the pharmacodynamic (PD) profile of BCG for therapeutic use in the adjuvant treatment of intermediate- and high-risk NMIBC after transurethral resection of bladder tumors. Study design: This study adopts a randomized, double-blind, active-controlled, multi-center trial design, including three phases: screening period, treatment period and follow-up period. In this study, 438 subjects will be randomly assigned to the experimental group and the control group in a 1:1 ratio, with 219 patients in both the experimental group and the control group, and stratified according to the baseline risk level (high-risk/intermediate-risk) and whether or not to perform urine PD sample collection (yes/no).

Plain Language Summary

Simplified for easier understanding

This Phase III clinical trial is testing a BCG treatment — a type of immunotherapy — delivered directly into the bladder for people with early-stage bladder cancer that has not invaded the muscle wall. The study aims to confirm the safety and effectiveness of this treatment. **You may be eligible if...** - You are 18 or older - You have been diagnosed with intermediate- or high-risk non-muscle-invasive bladder cancer (stages T1, Ta, or Tis), confirmed by a tissue sample - You have already undergone surgical removal of the visible bladder tumors - No visible tumor remains after surgery - You need BCG bladder treatment as part of your standard care **You may NOT be eligible if...** - You have muscle-invasive or metastatic bladder cancer - You have active urinary tract infections or certain other conditions that would make bladder instillation unsafe - You have incomplete pathology results Talk to your doctor to see if this trial is right for you.

Interventions

DRUGBCG for Therapeutic Use

After the subjects after transurethral bladder tumor resection were screened and randomly enrolled, the subjects were given intravesical infusion (experimental drug) within 2\~12 weeks after surgery, and perfused once a week for 6 consecutive times during the induction period; During the intensive phase, perfusion is given once every two weeks, 3 times in a row; During the maintenance period, perfusion was given once every 4 weeks, for a total of 19 perfusions, and the perfusion time continued until 1 year after surgery.
