About

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

Full 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).

Patients who have metastatic or locally advanced tumor but failed instandard treatments or not suitable for standard treatments;
According to RECIST (V1.1), the efficacy evaluation criteria for solid tumors, there is at least one measurable lesion.
Participants with Performance Scale (PS) of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) PS
Participants must have at least 1 lesion amenable to the mandatory fresh tumor biopsy at study entry
Fertile patients must agree to use a reliable contraceptive methods (hormonal or barrier methods or abstinence) during the trial and for at least 12 weeks after the last treatment;
The subject voluntarily participates and signs ICF (Informed consent forms).
