What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 66 participants in total. It began in 2024-07-24 with a primary completion date of 2027-07-31.

Brief Summary

This study employs a randomized, controlled, exploratory clinical trial design, with a planned enrollment of 66 patients who have previously failed systemic chemotherapy for recurrent/metastatic gastric cancer,

Eligibility Criteria

Inclusion Criteria: * 1\. Patients with advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma diagnosed by histology or cytology; * 2\. Patients who have previously failed first-line treatment including systemic chemotherapy and immune checkpoint inhibitors, and have maintained first-line use of immune checkpoint inhibitors for at least 3 months; * 3\. According to the evaluation criteria for solid tumor efficacy 1.1 (RECIST v1.1), there should be at least one measurable lesion that has not received local treatment such as radiotherapy (lesions located within the previously irradiated area can also be selected as target lesions if progression is confirmed); * 4\. ECOG score: 0-1 point; * 5\. Expected survival period ≥ 12 weeks; * 6\. The main organ functions well and the laboratory test data meets the following standards: (1) Blood routine: absolute neutrophil count ≥ 1.5 × 109/L (or greater than the lower limit of normal laboratory values in the research center), platelet count ≥ 100 × 109/L, hemoglobin ≥ 90g/L; (2) Liver function: serum total bilirubin ≤ 1.5 times the upper limit of the standard value (ULN), AST and ALT ≤ 2.5 times ULN. If the patient has liver metastasis, this standard is ≤ 5 times ULN; (3) Renal function: CrCl ≥ 60 ml/min/1.73 m2 (calculated according to the Cockcroft Gault formula); * 7\. Female subjects with fertility, as well as male subjects with partners who are fertility women, are required to use a medically approved contraceptive measure (such as intrauterine device, contraceptive pill, or condom) during the study treatment period, at least 6 months after the last use of Adebrelimab, and at least 6 months after the last use of chemotherapy; * 8\. Voluntarily join this study, sign the informed consent form, have good compliance, and cooperate with follow-up. Exclusion Criteria: * 1\. History of gastrointestinal perforation and/or fistula within 6 months prior to the first use of medication; * 2\. There is uncontrollable pleural effusion, pericardial effusion, or peritoneal effusion that requires repeated drainage; * 3\. History of allergies to any component of Adebrelimab in the past; * 4\. Have received any of the following treatments: 1. Received any other investigational drug within 4 weeks prior to the first use of the investigational drug or had a half-life of no more than 5 from the last investigational drug; 2. Simultaneously enrolled in another clinical study, unless it is an observational (non interventional) clinical study or an interventional clinical study follow-up; 3. Received anti-tumor therapy (including radiotherapy, chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, or tumor embolization) within 2 weeks prior to the first use of the investigational drug; 4. Subjects who need to receive corticosteroids (equivalent to\>10mg prednisone per day) within 2 weeks prior to the first use of the study drug. Allow the use of hormones for routine chemotherapy pretreatment without the need for dose adjustment. Other special circumstances require communication with the researcher. In the absence of active autoimmune diseases, inhalation or local use of steroids and corticosteroids with a dosage greater than 10mg/day of prednisone efficacy dose are allowed as substitutes for adrenal cortex hormones; 5. Individuals who have received anti-tumor vaccines or have received live vaccines within 4 weeks prior to the first administration of the study drug; 6. Having undergone major surgery or suffered severe trauma within 4 weeks prior to the first use of the investigational drug; 7. Patients who have received previous treatment with paclitaxel drugs; * 5\. The toxicity of previous anti-tumor treatments has not recovered to ≤ CTCAE 5.0 Grade 1 (excluding hair loss) or the level specified in the inclusion/exclusion criteria; * 6\. Patients with active central nervous system metastases; * 7\. Active autoimmune diseases, history of autoimmune diseases (such as interstitial pneumonia, colitis, hepatitis, pituitary inflammation, vasculitis, nephritis, hyperthyroidism, hypothyroidism, including but not limited to the above diseases or syndromes); Excluding childhood asthma/allergies with vitiligo or those who have already recovered, patients who do not require any intervention in adulthood; Autoimmune mediated hypothyroidism treated with stable doses of thyroid replacement hormone; Type I diabetes with a stable dose of insulin; * 8\. Have a history of immune deficiency, including HIV test positive, or have other acquired or congenital immune deficiency diseases, or have a history of organ transplantation and allogeneic bone marrow transplantation, or active hepatitis (hepatitis B reference: HBV DNA test value exceeds 500 IU/ml or 2500 copies/mL); * 9\. The subject has uncontrolled cardiovascular clinical symptoms or diseases, including but not limited to: (1) NYHA class II or above heart failure; (2) Unstable angina pectoris; (3) Have experienced myocardial infarction within one year; (4) Clinically significant supraventricular or ventricular arrhythmias that have not been clinically intervened or are still poorly controlled after clinical intervention; * 10\. Within 4 weeks prior to the first use of the investigational drug, there has been a severe infection (CTCAE 5.0\>grade 2), such as severe pneumonia requiring hospitalization, bacteremia, infection complications, etc; Baseline chest imaging examination suggests the presence of active pulmonary inflammation, symptoms and signs of infection within 2 weeks prior to the first use of the study drug, or the need for oral or intravenous antibiotic treatment, except for prophylactic use of antibiotics; * 11\. History of interstitial lung disease (excluding history of radiation pneumonia and non infectious pneumonia that have not been treated with steroids); * 12\. Patients with active pulmonary tuberculosis infection found through medical history or CT examination, or patients with a history of active pulmonary tuberculosis infection within the past year before enrollment, or patients with a history of active pulmonary tuberculosis infection more than one year ago but without formal treatment; * 13\. Diagnosed with any other malignant tumor within 5 years prior to the first use of the investigational drug, except for malignant tumors with low-risk metastasis and mortality risk (5-year survival rate\>90%), such as basal cell or squamous cell carcinoma or cervical carcinoma in situ that have been adequately treated; * 14\. Pregnant or lactating women; * 15\. According to the researcher's assessment, there may be other factors that could force the subject to terminate the study midway, such as having other serious illnesses (including mental illnesses) that require concurrent treatment, severe abnormal laboratory test values, family or social factors that may affect the subject's safety or the collection of trial data.
