Newly formed French biotech Kahimmune Therapeutics has signed an exclusive licensing agreement with Gustave Roussy and SATT Paris-Saclay, securing rights to a technology platform designed to identify tumor antigens derived from the “dark” or non-coding genome. The spin-off, created in late 2025, plans to use the licensed technology to develop shared mRNA cancer vaccines, with an initial program targeting colorectal and pancreatic cancer.
