Results from a trial presented at ESMO 205 have shown that a targeted therapy combination improved outcomes for patients with metastatic clear-cell renal carcinoma (ccRCC) whose disease progressed following immunotherapy.
Data from the LenCabo Phase II trial were presented today by Andrew W. Hahn, M.D. (Abstract LBA94).
The randomised study found that patients whose disease worsened after immunotherapy and who were treated with the combination of lenvatinib and everolimus lived longer without disease progression compared to those who received cabozantinib.
“This is the first randomised trial to compare these two commonly used second-line treatments directly,” Hahn said.
“These findings offer insights into treatment sequencing and the importance of generating head-to-head data to guide clinical decisions.”
The trial enrolled 90 patients with metastatic or advanced ccRCC or RCC who had previously received one or two treatments, including at least one immunotherapy targeting PD-1 or PD-L1.
Of those treated with lenvatinib and everolimus, 62.5% saw cancer progression in comparison to 76% of those who received cabozantinib.
Those treated with lenvatinib plus everolimus had a median progression-free survival (PFS) of 15.7 months compared to 10.2 months for those receiving cabozantinib.
Current first-line treatment for patients with metastatic ccRCC consists of immune checkpoint inhibitors, sometimes combined with targeted therapies.
If the cancer stops responding to these treatments, the next treatment options include lenvatinib and everolimus, or cabozantinib.
This trial was designed to evaluate the comparative efficacy of second-line therapies to identify the regimen that provides longer PFS and improved patient outcomes.
The findings suggest that lenvatinib plus everolimus may offer a more meaningful benefit as second-line treatment and may guide future treatment selection for patients in need.
