Patients will receive intramuscular injections of SapDM275 tumor vaccine combined with AG regimen until the occurrence of any of the following: disease progression, intolerable toxicity, death (whichever occurs first), the investigator's assessment that the subject is no longer suitable for further treatment, or withdrawal of consent by the subject.", 'detailedDescription': 'The dose escalation stage inclues two dose cohorts: 5×10⁶active particles and 5×10⁷active particles. Subjects in each cohort will receive a fixed dose via intramuscular injection on Day 1, Day 15, and Day 29.\n\nThe traditional3+3 dose-escalation design will be applied:\n\nThree subjects will be enrolled in each cohort. If no dose-limiting toxicity (DLT) is observed during the 35-day observation period, escalation to the next dose level will proceed.\n\nIf two or more subjects experience DLTs, dose escalation will be terminated. If one subject experiences a DLT, three additional subjects will be enrolled at the same dose level.\n\nIf no DLT occurs in these additional three subjects, escalation to the next dose level will proceed.\n\nIf one DLT occurs among the additional three subjects, dose escalation will be terminated.\n\nDose expansion stage When the high-dose group (5×107 active particles group) in the dose escalation stage achieve good safety profile, a further expansion stage is expected includes a total of approximately 10 subjects (including those in the dose escalation stage).\n\nWhen ≥2/6 of the patients in the high-dose group (5×107 active particles group) developed DLT during the dose escalation stage, further expansion will return to the low-dose group (5×106 active particles group). The low-dose group could reach a total of approximately 10 subjects (including subjects in the dose escalation stage).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
