Inclusion Criteria:
Age≥18 years old.
* Histologically or cytologically confirmed diagnosis of gastric cancer.
* Participants unresectable locally advanced or metastatic gastric cancer who had not received systemic treatment (participants who had progressed 6 months after prior neoadjuvant/adjuvant therapy could be enrolled).
* Confirmed to be HER2 positive (HER2-positive is defined as IHC 3+ or IHC 2+ with ISH positive) and PD-L1 status (participants of phase III should be confirmed by the pathology department of participating study center).
* Phase II: Presence of at least 1 measurable lesion per RECIST 1.1. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. Phase III:Presence of at least 1 evaluable lesion per RECIST 1.1. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
* ECOG PS of 0 - 1.
* Expected survival ≥ 3 months.
* Participants with adequate organ functions.
* Female and male participants of childbearing age agree to take adequate contraceptive measures during and upon completion of the study for 7 months after the last dose. Female participants of childbearing age must have a negative blood pregnancy test within 7 days before randomization.
* Voluntarily agree to participate in the study and sign the informed consent.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
