Conatumumab

Conatumumab 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 receptor 2 with potential antineoplastic activity. 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.
The drug was developed by Amgen Inc. In 2008, Takeda licensed the drug from Amgen for development in Japan, but discontinued development in 2011.
