Ellipses Pharma Ltd. has agreed to in-license global rights to GENA-104, a first-in-class immuno-oncology monoclonal antibody that targets CNTN4, from Genome & Co. Ltd. Targeting CNTN4 is a new approach that blocks the CNTN4-APP checkpoint interaction on T cells, promoting tumor cell killing, with potential use in cancers that respond poorly to conventional checkpoint inhibitors.
