Over the past few decades, the incidence of renal cell carcinoma (RCC) has rapidly increased with a considerable portion of patients presenting with metastatic disease (mRCC) and subsequent poor prognosis. Survival drops even further for those whose diseases progress on first-line therapy including immune-checkpoint inhibitors (ICIs) and vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs). In this review, we highlight the main second-line systemic therapies including TKIs, mTOR inhibitors, ICIs, and HIF-2α inhibitors along with their mechanisms of action and supporting clinical trials.
