Brief Summary

The study is to evaluate the safety and tolerability of SHR-1501 alone or in combination with BCG or SHR-1316 in the patients with NMIBC, and to determine the RP2D of SHR-1501 in combination with BCG or SHR-1316. To evaluate the preliminary efficacy of SHR-1501 alone or in combination with BCG or SHR-1316 in the treatment of NMIBC.
