Arms and Interventions

Arm Intervention/Treatment
Experimental: RC48-ADC + JS001

Participants received 6 preoperative cycles of RC48-ADC PLUS JS001, followed by surgery, followed by up to 20 cycles of postoperative JS001.

Drug: RC48-ADC
Drug: RC48-ADC 2.0 mg/kg by intravenous (IV) infusion, given on Day 1 of each 14-day cycle

Drug: JS001
Drug: JS001 3.0 mg/kg by intravenous (IV) infusion, given on Day 1 of each 14-day cycle

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-year Disease Free Survival Rate [From approximately 16 Weeks up to approximately 12 Months.]

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

  3. Objective Response Rate (ORR) [Up to approximately 12 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.
