First-in-Class monoclonal antibody
PBP1710 specifically binds to CTHRC1 and exerts anti-metastasis and anti-tumor growth effects
Mechanism of Action
CTHRC1 promotes cancer cell migration through activation of the Wnt5 signaling pathway by forming CTHRC1-Wnt5-Fzd2/Ror2 complexes on cancer cells.
CTHRC1 stimulates formation of blood vessels (angiogenesis) in tumor tissues by upregulating the secretion of Ang-2, a Tie2 ligand, from endothelial cells. Activation of Ang-2/Tie2 axis in monocytes is critical in tumor angiogenesis.
 Pan-cancer analysis combined with experiments predicts CTHRC1 as a therapeutic target for human cancers. Cancer Cell Int (2021).
