Brief Summary:
This trial is an investigator-initiated, single-center, open-label, single-arm exploratory study of mRNA neoantigen tumor vaccine in the treatment of advanced gastric cancer, esophageal cancer, and liver cancer, including two phases: dose escalation and dose expansion. To evaluate the safety and tolerability of neoantigen tumor vaccine in subjects with advanced gastric cancer, esophageal cancer and liver cancer by conducting dose escalation trial in subjects diagnosed with advanced gastric cancer, esophageal cancer and liver cancer, and preliminarily evaluate the efficacy of neoantigen tumor vaccine in subjects with advanced gastric cancer, esophageal cancer and liver cancer. According to the characteristics of safety and efficacy data in the dose escalation phase, the dose expansion is performed at the intended clinical dose based on the investigator's judgment, and the treatment is performed in combination with PD-1/L1 to further evaluate the efficacy and safety profile of neoantigen tumor vaccine at a specific dose.
Both the dose escalation phase and dose expansion phase include a screening period (Week -4 \~ Week -2), a baseline period (Week -1 \~ Day -1), a treatment period (Day 1 \~ Week 8 or 16), and a follow-up period. Subjects who signed and provided the formal informed consent entered the screening period. The treatment period included the initial treatment period (Day 1 \~ Week 8) and the enhanced treatment period (Week 12 \~ Week 16). The investigator determined whether to enter the enhanced treatment period based on the comprehensive judgment of the subject's efficacy, safety, compliance and other factors from Week 8 to Week 12.
The dose escalation phase follows standard 3+3 design. 12-18 subjects are expected to be enrolled at 3 given dose level.
The investigator will choose the optimal clinical dose for dose expansion, which can be one dose group or multiple dose groups. PD-1/L1 drugs are used in parallel to further confirm the efficacy and safety of neoantigen tumor vaccine, with about 18 subjects. The usage and dosage of PD-1/L1 should aligned with the package insert.
