Brief Summary

A single arm, open-label pilot study is designed to determine the safety, tolerability and effectiveness of personalized mRNA tumor vaccine encoding neoantigen in Patients with advanced esophageal cancer and non-small cell lung cancer

Detailed Description

Primary objectives:

Assessing the safety and tolerability of mRNA personalized tumor vaccines encoding neoantigen for unresectable or metastatic advanced esophageal and non-small cell lung cancers with standard treatment failure or no standard treatment.

Secondary objectives:

Preliminary observation of the efficacy of mRNA personalized tumor vaccines encoding neoantigen for unsurgically resected or metastatic advanced esophageal and non-small cell lung cancers with standard treatment failure or no standard treatment.
