Inclusion criteria
. Ability to understand and voluntarily sign a written informed consent form (ICF), which must be signed before the specified study procedures required for the study are performed.
. Males or females aged ≥ 18 to ≤ 75 years at the time of signing informed consent.
. Histopathologically confirmed gastric adenocarcinoma or gastroesophageal junction (GEJ) adenocarcinoma.
. Unresectable locally advanced or metastatic gastric adenocarcinoma or GEJ adenocarcinoma.
. Subjects have not received prior systemic therapy for locally advanced or metastatic gastric adenocarcinoma or adenocarcinoma of the gastroesophageal junction. For subjects who have received prior neoadjuvant/adjuvant chemotherapy or chemoradiotherapy for curative intent, the time between disease progression and last treatment should be at least 6 months.
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.
. Subjects have at least one measurable tumor lesion per RECIST v1.1; lesions that received radiotherapy are not selected as target lesions, unless the lesion is the only measurable lesion and has unequivocal progression as judged by imaging, it can be considered as a target lesion.
Exclusion criteria
. Subjects with known HER2-positive gastric or GEJ adenocarcinoma.
. Histopathology or cytology confirmed other pathological types, such as squamous cell carcinoma, sarcoma, or undifferentiated carcinoma.
. Subjects who received palliative local therapy for non-target lesions within 2 weeks prior to the first dose; systemic nonspecific immunomodulatory therapy (e.g., interleukin, interferon, thymosin, etc.) within 2 weeks prior to the first dose; and Chinese herbal medicine or traditional Chinese medicinal products with anti-tumor indications within 2 weeks prior to the first dose.
. Subjects who received any prior treatments targeting the mechanism of tumor immunity.
. Medical history of gastrointestinal perforation or gastrointestinal fistula within 6 months prior to the first dose. If the perforation or fistula has been treated with resection or repair and the disease has recovered or resolved as judged by the Investigator, enrollment may be allowed.
. Active or previously documented inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis).
. Active malignancies within the past 3 years, with the exception of tumors in this study and cured local tumors, such as basal cell carcinoma of skin, squamous cell carcinoma of skin, superficial bladder cancer, carcinoma in situ of cervix, carcinoma in situ of breast, localized prostate cancer, etc.
. Known active or untreated brain metastases, meningeal metastases, spinal cord compression, or leptomeningeal disease.
