Clinical Trial Summary

This study is a one-arm exploratory clinical study of Disitamab Vedotin for Injection combined with Penpulimab Injection designed for cisplatin intolerant CT2-T4anxm0 bladder urothelial carcinoma patients.It will confirme the efficacy and safety of Disitamab Vedotin for Injection combined with Penpulimab Injection neoadjuvant treatment for cisplatin intolerant CT2-T4anxm0 bladder urothelial carcinoma patients. Finally, it will provide new evidence-based medical evidence for neoadjuvant therapy for such patients.

Clinical Trial Description

This study is a multicenter, open-label, single-arm prospective clinical study to evaluate the neoadjuvant treatment of Disitamab Vedotin for Injection combined with Penpulimab Injection in cisplatin-intolerant cT2-T4aNxM0 bladder urothelial carcinoma Efficacy and safety in patients. If the subject does not withdraw from the trial voluntarily, the toxic and side effects caused by the drug are intolerable, or the investigator believes that the subject is not suitable for further trials, each subject will undergo the following treatment after surgery, and in Efficacy evaluation and follow-up were performed in each cycle. After completion of all screening activities, patients who are identified as eligible will enter the study and receive the following treatments and visits: Neoadjuvant therapy with Disitamab Vedotin for Injection combined with Penpulimab Injection (administered for a maximum of 4 cycles), every three One week is a medication cycle; patients received radical cystectomy after neoadjuvant chemotherapy; postoperative pathological complete remission rate, downstaging rate, and regular follow-up for two years were evaluated to evaluate the safety of the patients drugs/surgery, and to evaluate the patients new Survival after curative resection with adjuvant immunotherapy combined with chemotherapy. Neoadjuvant regimen (up to 4 cycles): Disitamab Vedotin for Injection, 2.0 mg/kg, given as an IV infusion on day 1, and Penpulimab Injection, 200 mg, on every 21 days On day 1 of the cycle, it is given as an intravenous infusion. Order of use: Disitamab Vedotin for Injection → Penpulimab Injection. Surgical plan: radical cystectomy + urinary diversion. ;
