Neon Therapeutics is a clinical-stage immuno-oncology company. The Company is focused on developing therapeutics leveraging neoantigen biology to treat cancer. The Company's neoantigen-based product engine allows it to develop multiple treatment modalities, including vaccines and thymus (T) cell therapies targeting both personalized and shared neoantigens. The Company's neoantigen-based product engine targets both neoantigens that are specific to individual patients, as well as neoantigens that are shared across patients and tumor types. The Company's NEO-PV-01 program is a personalized neoantigen vaccine. NEO-PV-01 utilizes an epitope computational engine called Real-time Epitope Computation for Oncology (RECON). The Company's NEO-PTC-01 is an Adoptive T Cell Therapy. NEO-PTC-01 uses immunogens in co-culture with T cells and monocyte-derived dendritic cells from patients in order to ex vivo stimulate autologous T cells to respond against neoantigen targets.
