Anti-cancer Neoantigen mRNA Vaccine to Treat Solid Tumors

Anti-cancer Neoantigen mRNA Vaccine to Treat Advanced Solid Tumors: Phase I Clinical Trial

The WES and RAN-seq will be performed to identify and verify neoantigens and appropriate mRNA sequences will be verified, manufactured and protected for vaccine production by multiple in vitro and in vivo studies. Clinical studies will be performed to test anti-cancer function of the mRNA vaccine for immunotherapy of human cancer patients. In this phase I study, the safety, tolerance, and preliminary efficacy of the mRNA vaccine immunotherapy on human cancers will firstly be evaluated.

1. Choose appropriate patients with advanced solid cancers, with written consent for this study;
2. Perform biopsy to get fresh sample for DNA/RNA-seqencings and bioinformatics analysis;
3. Produce high quality mRNA vaccine and deliver the vaccine into selected patients via local injections, and follow up closely to collect related results as required;
4. To enhance the killing capability, cotreatment the patients with PD1/PDL1/CTLA4 antibodies may be applied;
5. Evaluate the clinical results as needed.

Inclusion Criteria:

1. Patients with advanced cancer; 2. Life expectancy >12 weeks; 3. Adequate heart, lung, liver, kidney, and blood function; 4. Available high quality vaccine for human use; 5. Informed consent explained to, understood by and signed by patient/guardian. Patient/guardian given copy of informed consent.
