Biological: Personalized neoantigen tumor vaccine
neoantigen tumor vaccine with or without Pembrolizumab In dose escalation phase, subjects will receive neoantigen tumor vaccine only. In dose expansion phase, subjects will receive neoantigen tumor vaccine combination with Pembrolizumab |
- Maximum tolerated dose (MTD) or Dose-limiting toxicity(DLT),If MTD is not reached, Biologically Effective Dose (BED) [ Time Frame: Up to 27 weeks ]The highest dose of a drug or treatment that does not cause unacceptable side effects.
- Reaction of antigen-specific T cells in peripheral blood [ Time Frame: Up to 27 weeks ]mRNA-0217/S001 personalized tumor vaccine induced neoantigen-specific CD4+ and CD8+ T lymphocyte responses
- Objective response rate (ORR) [ Time Frame: Up to 105 weeks ]ORR calculates the ratio of the number of patients whose best response is complete remission (CR) or partial remission (PR) to the total number of evaluable patients according to RECIST 1.1 criteria. Those who have not been evaluated for lesion and tumor response will be regarded as non-evaluable patients and will not be counted.
- Disease control rate (DCR) [ Time Frame: Up to 105 weeks ]DCR calculates the ratio of the number of patients whose best response is complete remission (CR), or partial remission (PR), or stable disease (SD) to the total number of evaluable patients according to RECIST 1.1 criteria. Those who have not been evaluated for lesion and tumor response will be regarded as non-evaluable patients and will not be counted.
- Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 [ Time Frame: Up to 105 weeks ]
During the trial conduction, all adverse events (including laboratory abnormality and clinical events) will be closely monitored, and all ≥ grade 3 adverse events per CTCAE (v 5.0) will be recorded, including but not limited to the toxicities potentially suspected to relate to injection procedures and/or mRNA Tumor Vaccine therapy as listed below:
Local erythema at the injection site, local allergic reactions at the injection site, fatigue, fever, chills, flu-like manifestations, vomiting, centrocytopenia, other unexpected adverse events
- Progression-free survival (PFS) [ Time Frame: Up to 105 weeks ]Progression-free Survival of Personalized mRNA Tumor Vaccine
- overall survival (OS) [ Time Frame: Up to 3 years ]Overall Survival of Personalized mRNA Tumor Vaccine
