Summary

This is a single-arm, open-label, Phase Ib/II clinical trial designed to evaluate the efficacy and safety of Disitamab Vedotin combined with Ivonescimab in the perioperative treatment of cisplatin-ineligible patients with muscle-invasive bladder cancer (MIBC). The study will enroll MIBC patients scheduled for radical cystectomy who have not received prior immunotherapy, targeted therapy, or biological therapy, except for cisplatin chemotherapy. The trial will consist of a neoadjuvant treatment phase (Disitamab Vedotin and Ivonescimab), followed by surgery and an adjuvant treatment phase. Primary efficacy endpoints include the pathological complete response (pCR) rate, while secondary endpoints include disease-free survival, recurrence-free survival, overall survival, and clinical objective response rate. Safety will be monitored throughout the study, and biomarker testing (HER2 and PD-L1) will be conducted to assess treatment efficacy. The study aims to explore the potential of this combination therapy in improving outcomes for MIBC patients.

Conditions

Interventions

DRUG

Disitamab Vedotin Injection

Participants will receive Disitamab Vedotin at a dose of 2.0 mg/kg. In the neoadjuvant phase, it will be administered every 2 weeks for 6 cycles (12 weeks total). In the postoperative adjuvant phase, it will be administered every 3 weeks for 4 cycles, starting 4-8 weeks after surgery.

DRUG

Ivonescimab(AK112,a PD-1/VEGF bispecific antibody)

Participants will receive Ivonescimab at a dose of 20 mg/kg. In the neoadjuvant phase, it will be administered every 3 weeks for 4 cycles (12 weeks total). In the postoperative adjuvant phase, it will be administered every 3 weeks for 9 cycles, starting 4-8 weeks after surgery.

PROCEDURE

Radical Cystectomy with Pelvic Lymph Node Dissection

Participants will undergo radical cystectomy with pelvic lymph node dissection 4-6 weeks after the last dose of neoadjuvant treatment.
