KD014 (DX-2400) is a human monoclonal antibody (mAb) targeting MMP14 (Ki: 0.9 nM) . KD014 inhibits TGFβ and SMAD2/3 activity, increases macrophage numbers and iNOS expression, and shifts macrophage phenotype toward anti-tumor M1-like. KD014 has anti-tumor activity in three different tumor models (MDA-MB-231, MDA-MB-435, and PC3) . KD014 can be used in breast cancer research[1][2].
