First-line treatments for advanced renal-cell carcinoma with immune checkpoint inhibitors: systematic review, network meta-analysis and cost-effectiveness analysis.

BACKGROUND

Immune checkpoint inhibitors (ICIs) are effective for advanced renal-cell carcinoma (aRCC) but can increase costs. This study compares the efficacy, safety and cost-effectiveness of ICIs for newly diagnosed aRCC patients in the first-line setting.

METHODS

Trials evaluating ICI regimens as first-line treatment for newly diagnosed aRCC were searched and included. A network meta-analysis (NMA) was conducted, and a cost-effectiveness analysis was performed from the US payer's perspective. The key outcomes were overall survival (OS) and progression-free survival (PFS) in the NMA, and quality-adjusted life years (QALYs), costs and the incremental cost-effectiveness ratio (ICER) in the cost-effectiveness analysis.

RESULTS

Four randomized controlled trials (RCTs) involving 3758 patients receiving first-line ICIs treatment were analyzed. The NMA showed that pembrolizumab plus axitinib was ranked higher than the other three ICI regimens and sunitinib in the overall population. Nivolumab plus ipilimumab and pembrolizumab plus axitinib achieved more health benefits than the other ICI regimens and sunitinib in programmed death ligand 1 (PD-L1)-positive and negative tumors, respectively. Among the four ICI regimens, only the ICERs of nivolumab plus ipilimumab over sunitinib were lower than the willingness-to-pay threshold ($150,000/QALY) in the overall and PD-L1-positive populations, and none of four ICI regimens were lower than $150,000/QALY in PD-L1-negative populations.

CONCLUSIONS

The NMA and cost-effectiveness analysis revealed that nivolumab plus ipilimumab is the most favorable first-line treatment for PD-L1-positive aRCC compared with other ICI regimens and sunitinib. Pembrolizumab plus axitinib is likely to be an alternative for PD-L1-negative aRCC due to its more favorable health advantages.
