Conatumumab (originally AMG-655) is a monoclonal antibody developed for the treatment of cancer. It is a fully human monoclonal agonist antibody directed against the extracellular domain of human TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) receptor 2 (TR-2, death receptor 5) with potential antineoplastic activity.^[1]^[2] Conatumumab mimics the activity of native TRAIL, binding to and activating TR-2, thereby activating caspase cascades and inducing tumor cell apoptosis. TR-2 is expressed by a variety of solid tumors and cancers of hematopoietic origin.^[3]^[4]

The drug was developed by Amgen Inc. In 2008, Takeda licensed the drug from Amgen for development in Japan, but discontinued development in 2011.
