Abstract:
This paper aims to compare the approved second-line treatment options in metastatic renal cell carcinoma. A network meta-analysis (NMA) using the frequentist approach and generalized pairwise modeling was computed for the approved drugs in this setting. The results of this NMA showed that the combination of lenvatinib and everolimus yielded the lowest hazard ratio (HR) for progression-free survival (HR: 0.4; 95% CI: 0.21-0.75) and overall survival (HR: 0.55; 95% CI: 0.30-1.00). The great efficacy of this combination is limited by the prevalence of grade 3-4 adverse events (70.6%) leading to treatment discontinuation in 17.6%. This NMA is to the best of our knowledge, the first analysis of the approved regimens for the second-line treatment of metastatic renal cell carcinoma.
Insights
The combination of lenvatinib and everolimus is the most effective second-line treatment for metastatic renal cell carcinoma, despite significant side effects. This finding comes from the first network meta-analysis of approved therapies.
Area of Science:
- Oncology
- Pharmacology
Background:
- Metastatic renal cell carcinoma (mRCC) presents significant treatment challenges.
- Identifying optimal second-line therapies is crucial for improving patient outcomes.
Purpose of the Study:
- To compare approved second-line treatment options for metastatic renal cell carcinoma.
- To evaluate the efficacy and safety of various drug regimens using network meta-analysis.
Main Methods:
- A frequentist network meta-analysis (NMA) was performed.
- Generalized pairwise modeling was employed to analyze approved drugs in the second-line setting.
Main Results:
- The combination of lenvatinib and everolimus demonstrated the lowest hazard ratio (HR) for progression-free survival (HR: 0.4) and overall survival (HR: 0.55).
- This combination was associated with a high incidence of grade 3-4 adverse events (70.6%), leading to treatment discontinuation in 17.6% of patients.
Conclusions:
- Lenvatinib plus everolimus shows superior efficacy in second-line treatment for mRCC.
- The significant toxicity profile necessitates careful patient selection and management.
