ABSTRACT
Introduction: Renal cell carcinoma (RCC) represents a heterogeneous group of cancers with distinct histological features, molecular alterations, prognosis, and response to therapy. Target agents directed against vascular endothelial growth factor and its receptor and mammalian target of rapamycin (mTOR) inhibitors have completely changed the landscape of RCC. However, the rate of complete response is still low, thus supporting the research of novel therapeutic agents.
Area covered: The authors describe the chemical features of tivozanib, its pharmacodynamic and pharmacokinetic properties, and the results obtained in human phase I–III clinical trials. Tivozanib received its first global approval in EU, Iceland, and Norway on 28 August 2017 for the first-line treatment of adult patients with advanced RCC and for adult patients who are VEGFR and mTOR inhibitor-naive following disease progression after one prior treatment with cytokines.
Expert opinion: The US Food and Drug Administration did not approve tivozanib due to the lack of a significant advantage in terms of survival compared to sorafenib. To date, the role of tivozanib in the pharmaceutical landscape of mRCC appears to be very limited. However, ongoing trials on the association between tivozanib and immunotherapy may represent a promising strategy to be assessed in future clinical trials.
