About Vigil® EATC: Vigil® autologous tumor cell therapy is an investigational technology that combines the concepts of genetic engineering with the science of immuno-oncology, to enable an immune response to cancer cells. Patient's own tumor cells are transfected with a DNA plasmid carrying the gene vector for a bifunctional shRNA targeting the knockdown of Furin accompanied with TGFß1 and 2 deletion and a vector for GM-CSF to elicit a systemic T-cell directed immune response when administered to the patient through intradermal injections. By utilizing the tumor cells as the antigen source, Vigil® EATC is designed to elicit specific immune response targeting each patient's unique and immunogenic tumor antigens. Vigil® EATC was studied in a nonrandomized, open-label Phase 1 trial in over 19 different solid tumor types and is currently being studied in Ewing's sarcoma and ovarian cancer as a single agent, and in breast cancer, non-small cell lung cancer and melanoma in combination with PD-1/PD-L1 inhibitors.
