简要总结

This is a Phase III, 3 arm, randomized, open-label, multi-center, global study assessing the efficacy and safety of rilvegostomig in combination with fluoropyrimidine and T-DXd (Arm A) compared to trastuzumab, chemotherapy, and pembrolizumab (Arm B) in HER2-positive locally advanced or metastatic gastric or GEJ adenocarcinoma participants whose tumors express PD-L1 CPS grater then equals to 1. Rilvegostomig in combination with trastuzumab and chemotherapy will be evaluated in a separate arm (Arm C) to assess the contribution of each component in the experimental arm.

Approximately 1680 participants with LA-HNSCC are planned to be screened in order to randomize approximately 880 participants in a 1:1:1 ratio to one of the following arms:

Arm

Study Intervention

Dose and Route of Administration

|Arm A

T-DXd + Rilvegostomig + Fluoropyrimidine: Capecitabine a OR 5-FU a

T-DXd: 5.4 mg/kg IV Q3W Rilvegostomig: 750 mg IV Q3W Capecitabine: 750 mg/m2 orally BID for 14 days, Q3W OR 5-FU: 600 mg/m2/day IV as a continuous infusion over 24 hours for the first 5 days of each cycle (120 hours or per local practice), Q3W

Arm B

Pembrolizumab + Trastuzumab + FP a OR CAPOX a

Pembrolizumab: 200 mg IV Q3W Trastuzumab: 8 mg/kg loading dose, followed by 6 mg/kg for subsequent cycles, IV Q3W FP: Cisplatin: 80 mg/m2 IV + 5-FU: 800 mg/m2/day IV as a continuous infusion over 24 hours for the first 5 days of each cycle (120 hours or per local practice), Q3W OR CAPOX: Capecitabine: 1000 mg/m2 orally BID for 14 days + oxaliplatin: 130 mg/m2 IV Q3W

Arm C

Rilvegostomig + Trastuzumab + FP a OR CAPOX a

Rilvegostomig: 750 mg IV Q3W Trastuzumab: 8 mg/kg loading dose, followed by 6 mg/kg for subsequent cycles, IV Q3W FP: Cisplatin: 80 mg/m2 IV + 5-FU: 800 mg/m2/day IV as a continuous infusion over 24 hours for the first 5 days of each cycle (120 hours or per local practice), Q3W OR CAPOX: Capecitabine: 1000 mg/m2 orally BID for 14 days + oxaliplatin: 130 mg/m2 IV Q3W

Randomization will be stratified by HER2 status (IHC 3plus versus IHC 2plus plus ISH-positive), geographic region (Japan/South Korea versus Rest of Asia [including China] versus North America/EU/ROW), and PD-L1 expression (CPS grater then equals  10 versus CPS less than 10).

Randomization of participants with CPS of 1 to less than10 (inclusive of 1 but less than 10) will be capped at approximately 60% of the planned total number of randomized participants to reflect the natural prevalence of PD-L1 expression.

All randomized participants will receive the assigned study interventions until RECIST v1.1defined PD or unacceptable toxicity, withdrawal of consent, or other criteria for discontinuation are met. Cisplatin and oxaliplatin will be administered for up to 6 cycles as tolerated and as per local guidelines. Oxaliplatin may be continued up to 8 cycles at the discretion of the Investigator.

Participants found to derive benefit from and tolerate treatment may continue study intervention after disease progression and separate informed consent needs to be provided.

Participants will receive study intervention for a maximum of 12 months or 18 cycles, or undergo observation for 12 months, or until RECIST 1.1 defined radiological PD confirmed by investigator assessment, unless there is evidence of unacceptable toxicity, or if a participant requests to stop the study intervention, as applicable to the arm participants are assigned to

Follow-up of Participants Post-discontinuation of Study Intervention:

After study intervention discontinuation, all participants will undergo an EoT Visit or early study intervention/discontinuation Visit (within 7 days of discontinuation) and will be followed up for safety assessments 30 (Plus 7), 60 (Plus 7), and 90 (Plus 7) days after their last dose of study intervention (ie, the safety follow up visit).

Participants who have discontinued study intervention in the absence of RECIST v1.1 defined radiological progression confirmed by BICR assessment will be followed up with tumor assessments according to the SoA until RECIST v1.1 defined PD by BICR assessment or death regardless of whether or not the participant started a subsequent anti-cancer therapy, unless they have withdrawn all consent to study-related assessments.

In addition, all participants will be followed up for survival status after intervention discontinuation Q3M ( 2 weeks) from the date of randomization until death, withdra wal of consent, or the end of the study (ie, progression/survival follow-up), as per the SoA.
