Carotuximab (DE-122) is a novel endocholine antibody with strong antiangiogenic and anti-inflammatory activity. Carotuximab blocks endothelial glycoprotein (CD105) and its downstream Smad signaling pathway. Carotuximab has immunomodulatory and antitumor effects to prevent human endothelial dysfunction induced by hypercholesterolemia and hyperglycemia.
