What this Trial Is About
Researchers are evaluating the safety and preliminary effectiveness of BH011, a treatment for patients with high-risk non-muscle invasive bladder cancer (NMIBC) who have not responded to Bacillus Calmette-Guerin (BCG) therapy. This study addresses the need for alternatives to cystectomy, a major surgery often recommended after BCG failure, which carries significant risks and long-term impacts on quality of life. Many patients at this stage do not show muscle invasion or metastasis, making surgery a difficult decision. BH011 offers a potential treatment option for this group. In this Phase I/II open-label study, patients will receive BH011 administered directly into the bladder through a urinary catheter. Treatment begins 2 to 8 weeks after tumor removal by transurethral resection of bladder tumor (TURBT). BH011 is given once weekly for 6 weeks during an initial induction phase, followed by monthly doses for up to 12 months in a maintenance phase. Patients will undergo cystoscopy, urine cytology, and biopsy every 3 months for up to 24 months to monitor treatment effects. During the study, participants will be closely monitored for safety, including treatment-emergent adverse events from the first dose until 30 days after the last dose. Effectiveness will be assessed by measuring the complete response rate at 3 months. The study includes regular examinations and tests to confirm tumor status and overall health. The total participation time covers treatment and follow-up assessments for up to two years.
