A Randomized Controlled Study of 2nd-line Treatment of Advanced G/GEJ Adenocarcinoma With Fruquintinib and Albumin-paclitaxel in Combination With or Without PD-1 Antibody in Patients Who Have Failed Treatment With PD-1 Antibody
To explore the efficacy and safety of fruquintinib and albumin-paclitaxel combined with or without PD-1 antibody in the second-line treatment of advanced gastric/gastroesophageal junction adenocarcinoma that failed to be treated by anti-PD-1 /PD-L1 regimen
• Have fully understood the study and voluntarily signed the informed consent;
• Age ≥18 years old;
• Pathologically confirmed advanced gastric/gastroesophageal junction adenocarcinoma with at least one systemic treatment;
• Frontline experienced exposure to immune drugs (including exposure to PD-1 drugs in the neoadjuvant, adjuvant, and systemic treatment stages; For patients with metastasis and recurrence within 6 months after the end of adjuvant/neoadjuvant system treatment, the above-mentioned treatment is first-line treatment);
• ECOG's physical condition was 0-1, and did not deteriorate within 7 days;
• BMI≥18;
• Expected survival ≥3 months;
• The functions of vital organs meet the following requirements (the use of any blood components and cell growth factors is not allowed within the first 14 days of enrollment) a) Absolute neutrophil count ≥1.5×109/L, white blood cell ≥4.0×109/L; b) Platelet ≥100×109/L; c) Hemoglobin ≥90g/L; d) Total bilirubin TBIL≤1.5 times ULN; e)ALT and AST≤2.5 times ULN (up to 5 times in patients with liver metastasis); f) Urea/urea nitrogen (BUN) and creatinine (Cr) ≤1.5×ULN (and creatinine clearance (CCr) ≥ 50mL/min); g) Left ventricular ejection fraction (LVEF) ≥50%; h)Fridericia's corrected QT interval (QTcF) \<470 ms. i) INR≤1.5 x ULN, APTT≤1.5 x ULN.
