Rivoceranib, also known as apatinib, is a tyrosine kinase inhibitor that selectively inhibits the vascular endothelial growth factor receptor-2 (VEGFR2, also known as KDR). It is an orally bioavailable, small molecule agent which is thought to inhibit angiogenesis in cancer cells; specifically, rivoceranib inhibits VEGF-mediated endothelial cell migration and proliferation thus blocking new blood vessel formation in tumor tissue. This agent also mildly inhibits c-Kit and c-SRC tyrosine kinases.

Apatinib was first synthesized by Advenchen Laboratories in California, US and licensed out global rights to HLB (Korea) in 2020, and is being developed by Jiangsu Hengrui Medicine (China), LSK BioPartners (US) and HLB Life Science (Korea). It is an investigational cancer drug undergoing clinical trials as a potential targeted treatment for metastatic gastric carcinoma, metastatic breast cancer, adenoid cystic carcinoma, and advanced hepatocellular carcinoma.
