This is a phase II study to determine the safety and efficacy of tislelizumab when given in combination with nab-paclitaxel as treatment for patients with high-risk non-muscle-invasive bladder cancer (HR NMIBC) which is not completely resectable. Patients will receive treatment with tislelizumab in combination with nab-paclitaxel every 3 weeks for 4 treatment cycles over 12 weeks followed by transurethral resection biopsy.
