- •ECOG: 0-1
- •Expected survival ≥12 weeks;
- •Good blood reserve and liver, kidney and coagulation function
- •Willing to provide informed consent for study participation.
排除标准
- •Within the first 5 years of randomization, there is a history of malignant tumors other than GC/GEJ adenocarcinoma, except for skin basal cell carcinoma, cervical carcinoma in situ, breast carcinoma in situ, and skin squamous cell carcinoma that have been cured and cured after treatment
- •Individuals with a history of previous immunodeficiency, including those with other acquired or congenital immunodeficiency diseases, or those with a history of organ transplantation, allogeneic bone marrow transplantation, or autologous hematopoietic stem cell transplantation
- •Urine protein qualitative result ≥ 3+, or urine protein qualitative result is 2+and 24-hour urine protein quantification>1g
- •Individuals with a history of severe cardiovascular and cerebrovascular diseases
- •Individuals who are unable to control or have serious illnesses, including but not limited to active infections requiring systemic antibiotic treatment within 2 weeks prior to initial medication, interstitial pneumonia/lung disease requiring intervention during screening, and tumor related pain requiring local treatment during screening
- •Current peripheral sensory or motor neuropathy ≥ grade 2
- •Uncontrollable third space effusion in clinical practice

结局指标
主要结局
Overall Survival (OS)
时间窗: up to 42 months
OS was defined defined as the time from date of randomization until death from any cause.
Progression Free Survival (PFS)
时间窗: up to 42 months
PFS was defined as the time from date of randomization until first objective radiographic tumor progression or death from any cause, based on Investigator assessment
次要结局
