Personalized Medicine – a technical challenge for GMP Manufacturing of mRNA

Biopharmaceutical New Technologies (BioNTech) is a next generation immunotherapy company pioneering novel therapies for cancer and other serious diseases. The Company exploits a wide array of computational discovery and therapeutic drug platforms for the rapid development of novel biopharmaceuticals. Its broad portfolio of oncology product candidates includes individualized and off-the-shelf mRNA-based therapies, innovative chimeric antigen receptor T cells, bispecific checkpoint immuno-modulators, targeted cancer antibodies and small molecules. Based on its deep expertise in mRNA vaccine development and in-house manufacturing capabilities, BioNTech and its collaborators are developing multiple mRNA vaccine candidates for a range of infectious diseases alongside its diverse oncology pipeline.
iNeST (individualized Neoantigen Specific Therapies) immunotherapies are individualized cancer therapies tailored to a specific patient’s tumor. They contain unmodified, pharmacologically optimized mRNA encoding up to 20 patient-specific neoantigens. Neoantigens are proteins that are produced by cancer cells that differ from the proteins produced by healthy cells and are recognized by immune cells. The mRNA is encapsuled in BioNTech’s proprietary intravenous RNA-lipoplex delivery formulation which is designed to enhance stability as well as enable targeted delivery to dendritic cells. By analyzing each patient’s tumor, BioNTech is able to identify the cancer mutations that may act as neoantigens. Each individual cancer vaccine encodes for neoantigen candidates with the highest likelihood to help the immune system to recognize the cancer. For this purpose, BioNTech has developed a first of its kind, on-demand manufacturing process, following Good Manufacturing Practice (GMP) conditions.
