Summary

This is a phase II clinical study to evaluate the efficacy of RC48-ADC combined with toripalimab bladder-sparing therapy.

The RC48-ADC dose in this study is 2.0 mg/kg Q2W and toripalimab is 3 mg/kg Q2W.

This study plans to enroll 59 participants. The participants will start drug therapy within 2 weeks after the first diagnostic resection in the first stage, receiving RC48-ADC combined with toripalimab 3 times. At the 8th week after enrollment, the second stage of cystectomy was performed, and RC48-ADC combined with toripalimab was treated every two weeks thereafter for a total of 3 treatments. After the completion of the two-stage treatment, the participants should be discharged from the group by cystoscopy or other imaging examinations. On the contrary, if the participants have complete remission or partial remission, continue to the third stage of treatment, that is, receive RC48-ADC combined with toripalimab every two weeks for a total of 6 treatments, followed by cystoscopy, imaging, or a third cystectomy. If the participants achieve complete remission of the disease, maintenance immunotherapy will be given for 12 months. If the participants show that there is still a tumor, the participants will be discharged from the group for other treatments. Due to disease progression, death, participants voluntarily requested termination of study treatment, toxicity intolerance, initiation of new anti-tumor therapy, pregnancy, serious violation of the study process stipulated by the protocol, termination of study treatment determined by the investigator based on the best interests of the participants, loss to follow-up, whichever occurred first.

During the study, the first and second electrotoxic tissues were sequenced using RNA and single-cell sequencing, and ctDNA was tested in urine before treatment, in the third month, and in the sixth month.
