What is tusamitamab biosimilar research grade? Tusamitamab is a humanized IgG1-kappa monoclonal antibody targeting carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) which is overexpressed in tumors including non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC), and is an attractive target for therapies based on CAR-T cell or/and ADCs. Tusamitamab ravtansine (SAR408701) is an antibody-drug conjugate (ADC) combining a humanized monoclonal antibody and a potent cytotoxic maytansinoid derivative (DM4) inhibiting microtubule assembly. Tusamitamab biosimilar uses the same protein sequences as the therapeutic antibody tusamitamab.
