Advances in treatment of metastatic renal cell carcinoma.

PURPOSE OF REVIEW

Multiple agents, including vascular endothelial growth factor (VEGF) inhibitors and mammalian target of rapamycin inhibitors have been approved over the past decade for the treatment of metastatic renal cell carcinoma (mRCC). Here, we focus on nivolumab, cabozantinib, and lenvatinib plus everolimus, agents that have recently emerged with positive clinical data leading to 'Food and Drug Administration approval or pending approval in mRCC. We also review the development of novel agents of interest showing promise in mRCC as part of combination therapy'.

RECENT FINDINGS

Nivolumab and cabozantinib both offer improved survival over everolimus in the second-line treatment of mRCC. Lenvatinib plus everolimus has similarly shown encouraging survival benefits in a phase II trial for the second-line setting. Novel combinations in mRCC, including dual immune checkpoint blockade, VEGF and programmed death 1 inhibition, VEGF and vaccine therapy, dual angiogenic blockade, and VEGF-directed therapy with nanoparticle-containing camptothecin have shown promising activity in early-phase trials.

SUMMARY

Multiple promising agents are available in the treatment of mRCC. The appropriate sequencing of agents in the treatment of mRCC may become further elucidated by future studies that prospectively analyze potential biomarkers to identify patients who will derive the greatest benefit from VEGF, mammalian target of rapamycin, or checkpoint inhibitors.
