Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of Participants with Adverse Events (AEs) [safety and tolerability] | 21 days after last iNeo-Vac-R01 dose |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Recurrence Free Survival (RFS) | 3 years after first dose of iNeo-Vac-R01 | RFS is defined as time between the date of first dose of iNeo-Vac-R01 and the date of either disease recurrence or death (whichever is sooner). |
| The proportion of subjects who have no disease recurrence at 12 months or 24 months after first dose of iNeo-Vac-R01. | 12 months and 24 months after first dose of iNeo-Vac-R01 | — |
| Overall Survival (OS) | 3 years after first dose of iNeo-Vac-R01 | OS is defined as time between the date of the first dose of iNeo-Vac-R01 and the date of death due to any cause. |
| T Cell Subsets [immunogenicity] | 12 months after first dose of iNeo-Vac-R01 | Detect the proportion of different T cell subsets in T cells by flow cytometry. |
| Cytokines Level [immunogenicity] | 6 months after first dose of iNeo-Vac-R01 | Record the changes of IL-2, IL-6, IL-8, IL-10, IL-12, and TNF-α in peripheral blood before and after treatment. |
| Neoantigen-specific T Cell Response [immunogenicity] | 12 months after first dose of iNeo-Vac-R01 | Detect the level of specific TNF-γ in peripheral blood of subjects by ELISpot in order to measure the neoantigen-specific T cell response of subjects. |
