MEDI0639 (21H3RK) is a human monoclonal antibody (mAb) targeting DLL4. MEDI0639 inhibits Notch1 binding to Dll4. MEDI0639 reverses Notch1-mediated growth inhibition of human umbilical vein endothelial cells in vitro. MEDI0639 promotes human angiogenesis and reduces the number of vessels covered by smooth muscle actin-positive mural cells. MEDI0639 can be used in Small cell lung cancer and solid tumors research[1].
