Key Takeaways

  • FDA authorized belzutifan plus lenvatinib for advanced ccRCC in adults following progression on prior PD-1/PD-L1 inhibitor therapy.
  • A first-in-class oral HIF-2α inhibitor is paired with an oral multi-receptor TKI, providing a non–IO-based combination strategy in later lines.

FDA approved belzutifan plus lenvatinib for advanced ccRCC after PD-1/PD-L1 therapy, expanding treatment options for those with disease progression.

Yesterday, September 24, the FDA approved the dual regimen of belzutifan (WELIREG; Merck) plus lenvatinib (LENVIMA; Eisai) to treat adult patients with advanced renal cell carcinoma with a clear cell component (ccRCC) following a PD-1 or PD-L1 inhibitor.1

Belzutifan is a first-in-class oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor, and lenvatibib is an orally available multi-receptor tyrosine kinase inhibitor (TKI). Today’s decision was based on results from the phase 3 LITESPARK-011 trial (NCT04586231), which evaluated belzutifan plus lenvatinib vs cabozantinib (Cabotenyx; Exelixis) for patients with advanced ccRCC after treatment with a PD-1 or PD-L1 inhibitor.2

“While there has been much progress in the first-line treatment of advanced kidney cancer, we have limited options to offer patients if the disease progresses after treatment with a PD-1/PD-L1 immunotherapy,” Robert Motzer, MD, LITESPARK-011 principal investigator and genitourinary medical oncologist at Memorial Sloan Kettering Cancer Center, said in a news release. “With this FDA approval of belzutifan plus lenvatinib, we have a new treatment option for patients who progress following treatment with anti-PD-1/PD-L1 therapy—an important development for patients and the physicians who care for them.”
