Technical progress and main results achieved during SME Phase 1
1. PanCaVax vaccine adjuvant
• In Q4-2018, the role of single cytokines Interleukin-2 (IL-2), Interleukin-4 (IL-4), Interleukin-12 (IL-12) and GM-CSF on the activation of various immune cells (the multi-arm part of the immune system) has been established.
• In Q1-2, 2019, it has been shown that the application of the multi-cytokine adjuvant creates the optimal conditions for powerful and comprehensive cellular anti-tumor immune responses, engaging all cellular arms of the immune system.
2. PanCaVax vaccine target
• in Q1-2 2019, new organoid lines have been established for pancreatic cancer patients from the Department of Surgery MUMC.
• organoid lines CL-17 and CL-19 that have been cultured for DNA isolation and sequencing. These lines have been sequenced to select neo-antigens and to determine the presence of common neo-antigens among patients.
• the inclusion of liposome encapsulated mRNA into a five cytokines vaccine adjuvant protects the mRNA from destruction and leads to translation of the mRNA into the protein antigens and, most probably, to an immune response.
• results showed that RNAses in the inflammatory fluid did not destroy the mRNA. The injection of the multi-cytokine adjuvant created optimal conditions for extracellular translation of mRNA.
