Multikinase inhibitors (MKI) and
mammalian target of rapamycin (
mTOR) inhibitors prolong progression-free (PFS) and overall survival (OS) in the treatment of metastatic
renal cell carcinoma (mRCC) by reducing angiogenesis and
tumor growth. In this regard, the MKI
lenvatinib and the mTOR inhibitor
everolimus proved effective when applied alone, but more effective when they were administered combined. Recently, both drugs were included in clinical trials, resulting in international clinical guidelines for the treatment of mRCC. In May 2016,
lenvatinib was approved by the American Food and Drug Administration (FDA) for the use in combination with
everolimus, as treatment of advanced
renal cell carcinoma following one prior antiangiogenic
therapy. A major problem of treating mRCC with
lenvatinib and
everolimus is the serious adverse event (AE) of arterial
hypertension. During the treatment with
everolimus and
lenvatinib combined, 42% of the patients developed
hypertension, while 10% of the patients treated with
everolimus alone and 48% of the of the
lenvatinib only treated patients developed
hypertension.
Lenvatinib carries warnings and precautions for
hypertension,
cardiac failure, and other adverse events. Therefore, careful monitoring of the patients is necessary.
