ElyssaMed® is a spin-off of Gustave Roussy and INSERM. This biotech company is developing the first active cancer immunotherapy based on a cocktail of antigenic peptides (epitopes) derived from the ppCT tumor antigen delivered with an already marketed vaccine adjuvant for clinical use in non-small-cell lung cancer and neuroendocrine tumors. This innovative product, once administered to lung cancer patients, will amplify their specific immune response toward tumor cells expressing the ppCT antigen and lead to the destruction of even immune-escaped cancer cell variants.
