Clinical trial: Clinical Study of Personalized mRNA Vaccine Encoding Neoantigen in Patients With Advanced Esophageal Cancer and Non-small Cell Lung Cancer

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.
  Time of tumor progression (TTP); Disease Control Rate (DCR); Objective Remission Rate (ORR); Overall Survival (OS).
