Study Details

Study Description

Brief Summary

This study will evaluate the efficacy and safety of intravenous RC48-ADC combined with AK104 in perioperative treatment of muscle-invasive bladder cancer.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

36 patients with Muscle-invasive Bladder Cancer(MIBC) scheduled for radical cystectomy will participate in this study. The patient had not previously received any antitumor system therapy for MIBC. HER2 expression in MIBC patients is defined as the expression of HER2 in tumor tissues detected by immunohistochemistry (IHC) as IHC 1+, 2+, or 3+. After enrollment, the subjects will receive 4 cycles neoadjuvant therapy and 14 cycles adjuvant therapy.

Arms and Interventions

Arm Intervention/Treatment
Experimental: RC48-ADC +AK104

Participants received 4 preoperative cycles of RC48-ADC(2.0 mg/kg,Q2W) plus AK104(6.0 mg/kg,Q2W), followed by surgery, followed by up to 14 cycles of postoperative AK104(10 mg/kg,Q3W)and 6 cycles of postoperative RC48-ADC(2 mg/kg,Q3W)

Drug: RC48-ADC
4 preoperative cycles of RC48-ADC (2.0 mg/kg,intravenous (IV) infusion,Q2W), followed by surgery, followed by up to 6 cycles of postoperative RC48-ADC(2.0 mg/kg,intravenous (IV) infusion,Q3W)
Other Names:
  • Disitamab Vedotin
  • Drug: AK104
    4 preoperative cycles of AK104(6.0 mg/kg,intravenous (IV) infusion,Q2W), followed by surgery, followed by up to 14 cycles of postoperative AK104(10 mg/kg,intravenous (IV) infusion,Q3W)
    Other Names:
  • Cadonilimab Injection
  • Outcome Measures

    Primary Outcome Measures

    1. Pathologic Complete Response (pCR) Rate [Up to approximately 16 Weeks (Time of surgery)]

      pCR rate is defined as the percentage of participants having pCR. pCR is defined as absence of viable tumor (pT0pT0N0) in examined tissue from RC and PLND.

    Secondary Outcome Measures

    1. Rate of Pathologic Response [Up to approximately 16 Weeks (Time of surgery)]

      No residual tumor (ypT0N0) and partial response (ypTis-1N0) in surgical specimen.

    2. 1-3 year Disease Free Survival Rate [From approximately 12 Months up to approximately 36 Months]

      The percentage of participants disease free on 1-3 year after surgery.

    3. Objective Response Rate (ORR) [Up to approximately 16 Weeks]

      Objective Response Rate was defined as the percentage of participants with a complete response (CR) or partial response (PR)

    4. Overall Survival (OS) [Up to approximately 60 Months]

      Overall survival is defined as the time from enrollment to death due to any cause.
