The CLEAR study: design and rationale of the Phase III trial comparing RCC first-line treatment

Lay abstract

The latest clinical trial protocol published in Future Oncology describes the design and rationale of a Phase III trial designed to evaluate whether a combination of two targeted therapies (lenvatinib plus everolimus), or the combination of a single targeted therapy and a PD-1 inhibitor (lenvatinib plus pembrolizumab), would be superior to the standard therapy (sunitinib) for advanced or metastatic renal cell carcinoma patients (RCC).

Abstract

Aims: Lenvatinib plus everolimus is approved for the treatment of RCC after 1 prior vascular endothelial growth factor-targeted therapy. Lenvatinib plus pembrolizumab demonstrated promising antitumor activity in a Phase I/II trial of RCC.

Methods: We describe the rationale and design of the CLEAR study, a 3-arm Phase III trial comparing lenvatinib plus everolimus and lenvatinib plus pembrolizumab versus sunitinib monotherapy for first-line treatment of RCC. Eligible patients must have advanced clear cell RCC and must not have received any prior systemic anticancer therapy. The primary end point is progression-free survival; secondary end points include objective response rate, overall survival, safety, health-related quality of life, and pharmacokinetics. Biomarker evaluations are included as exploratory end points. ClinicalTrials.gov NCT02811861.
