Brief Summary
The study is to evaluate the safety and tolerability of intravesical FL115 alone or in combination with BCG in the patients with NMIBC, and to determine the RP2D of FL115 in combination with BCG. To evaluate the preliminary efficacy of FL115 alone or in combination with BCG in the treatment of NMIBC. The study consists of three parts: FL115 monotherapy dose escalation (Phase Ia), FL115 combined with BCG dose escalation (Phase Ib), and FL115 combined with BCG cohort expansion (Phase II). Each subject will receive FL115 alone or in combination with intravesical BCG, administered over three treatment periods: induction, enhanced induction/maintenance 1, and maintenance 2.
Eligibility Criteria
Inclusion Criteria: 1. Male or female subjects aged 18 years or older. 2. Histologic confirmation of non-muscle invasive bladder cancer of the transitional cell carcinoma high-grade subtype (mixed histology tumors allowed if transitional cell histology is predominant histology). 3. Histologically confirmed presence of BCG-unresponsive CIS (with or without Ta or T1 disease) or histologically confirmed presence of BCG-unresponsive high-grade Ta or T1 disease. 4. Absence of resectable disease after transurethral resection (TURBT) procedures (residual carcinoma in situ (CIS) acceptable; patients with T1 tumors must undergo repeat resection and biopsy \[inclusive of muscularis propria\] if initial biopsy did not include muscularis propria). Patients with high-grade Ta and/or T1 disease should have complete resection before study treatment. 5. Subjects refuse or are judged by the investigator not suitable for radical cystectomy. 6. ECOG score 0-2. 7. Expected survival ≥ 2 years (judged by th
