Adagene Inc. has announced a research collaboration with Sanofi SA, to find “masked” monoclonal and bispecific antibodies that are safer than marketed drugs in oncology, in a deal worth up to $2.5 billion plus royalties. San Diego and Suzhou, China-based Adagene will generate masked versions of Sanofi antibodies, taking responsibility for early stage research activities using its Safebody technology.

Researchers at Inserm have developed a method to direct pre-existing antibodies toward new targets. Their bimodular fusion proteins could be a broadly useful method for expanding access to antibody therapy. In a study that appeared in the Feb. 11, 2022, issue of Science Advances, the teams showed that antibodies to Epstein-Barr virus (EBV), which are present in 95% of the global population, could be redirected to a target cell of their choosing by fusing an EBV antigen to a cellular targeting ligand.
