KDR and renal cell carcinoma: In a phase III trial, investigating the survival benefits for patients with advanced renal-cell carcinoma upon dual targeting with checkpoint inhibitors and angiogenesis blockade, combined effects of pembrolizumab (anti-PD-1) with axitinib (VEGFR TKI) resulted in a significantly longer overall and -progression-free survival, as well as a higher objective response rate, compared to sunitinib (VEGFR TKI) treatment alone (222).
