A Pilot, Rapid Sequencing of First Line Cabozantinib, Ipilimumab and Nivolumab, and Lenvatinib and Everolimus in Patients with Metastatic or Unresectable Clear Cell Renal Cell Carcinoma

Description

This is a pilot, single-center, single-arm study where 20 patients with metastatic or unresectable clear cell renal cell carcinoma will receive same sequential treatment strategy (Cabozantinib for 12 weeks, then proceed with Ipilimumab plus Nivolumab immunotherapy x4 over 12 weeks, then subsequent therapies depending on treatment response for another 12 weeks \[Nivolumab for CR/PR/SD, Cabozantinib or Lenvatinib/Everolimus for PROG\]).Multi-targeted tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors represent two systemic modalities that has improved outcomes in patient with metastatic clear cell renal cell carcinoma (ccRCC). However, as an increasing number of treatment approaches has been sequentially approved in the front line setting, the optimal treatment selection and sequence have yet to be clearly defined. First line combination immunotherapy with nivolumab (PD-1 inhibitor) plus ipilimumab (CTLA-4 Inhibitor) has demonstrated improved overall survival and patient
