PG - 1935-43 LID - 10.1517/14740338.2015.1102883 [doi] AB - INTRODUCTION: Lenvatinib is an oral multitargeted tyrosine kinase inhibitor of VEGFR1,2,3,4, FGFR1,2,3,4, PDGFR-alpha as well as RET and KIT signaling network. Its activity against radioiodine-resistant differentiated thyroid cancer (DTC) has been recently demonstrated. Patients, who were given lenvatinib, showed significantly longer median progression free survival than placebo group, 18.3 vs 3.6 months, respectively. This review is focused on lenvatinib safety profile in patients treated due to DTC and medullary thyroid carcinoma. Among the most frequent lenvatinib-related adverse events (AEs) were hypertension, proteinuria, diarrhea, appetite decrease, weight loss, nausea and stomatitis. Although a lot of them were manageable, in 35-68% of patients dose reduction was required. Nevertheless, only 15% of subjects withdrew the drug due to its toxicity. AREAS COVERED: published results of clinical trials phase II and III investigating both safety and efficacy of lenvatinib in thyroid cancer. EXPERT OPINION: Lenvatinib shows acceptable safety profile in patients with thyroid carcinoma. Treatment-related side effects are usually manageable by dose modifications or by concomitant non-pharmacological and pharmacological treatment. However, the early recognition of any potential drug toxicity is crucial to avoid serious complications as well as to keep a patient on drug as long as the treatment is beneficial.
