Nivolumab Plus Axitinib in Patients With Anti-PD1 Refractory Advanced Melanoma

Nivolumab is a human IgG4 monoclonal antibody that blocks PD-1. It is a type of Immunotherapy and works as a checkpoint inhibitor, blocking a signal that prevents activation of T cells from attacking the cancer.

Axitinib (AG013736; trade name Inlyta) is a small molecule tyrosine kinase inhibitor.Its primary mechanism of action is thought to be vascular endothelial growth factor receptor 1-3, c-KIT and PDGFR inhibition, this, in turn, enables it to inhibit angiogenesis (the formation of new blood vessels by tumours)
