EVM16 Injection As a Single and Combination with Tislelizumab in Solid Tumors

Summary

The goal of this clinical trial is to learn the side effects, safety and effect of a tumor vaccine (EVM16) alone or in combined with an anti-PD-1 antibody (tislelizumab) . This clinical trial will include solid tumor patients who failed standard treatment. The main questions to answer are: Safety of EVM16. Suitable dose of EVM16. Effects of EVM16 combined with tislelizumab.
