Background of Ab2112-hIgG1

CD71, also known as the transferrin receptor 1 (“TfR1”), is a cell surface protein essential for iron uptake in dividing cells. CD71 is highly expressed in a number of solid and hematologic cancers and has attractive molecular properties for efficient delivery of cytotoxic payloads to tumor cells. CD71 has high potential as an anti-cancer target but is widely considered undruggable due to its presence on most dividing healthy cells.
