Overview

This is a combination therapy of three agents: pembrolizumab (a humanized monoclonal antibody against PD-1), belzutifan (a small molecule inhibitor of hypoxia-inducible factor 2-alpha, HIF-2α), and lenvatinib (a small molecule multi-kinase inhibitor targeting primarily vascular endothelial growth factor receptors VEGFR1-3, among others). The triplet regimen is under investigation as a first-line treatment for advanced or metastatic clear cell renal cell carcinoma (ccRCC) and other solid tumors, aiming to provide synergistic antitumor effects by engaging immune checkpoint inhibition, anti-angiogenesis, and tumor hypoxia modulation pathways. This combination is being tested in large phase 3 clinical trials for ccRCC and earlier-phase studies in other solid tumors. Merck (MSD) leads the development of both pembrolizumab and belzutifan; lenvatinib is developed by Eisai, often in collaboration with Merck[1][2][4][5][7][9].
