Abstract
Aim: To evaluate the cost–effectiveness of atezolizumab plus nab-paclitaxel (ANP) in the first-line treatment of metastatic triple-negative breast cancer (TNBC). Materials & methods: We developed a Markov model to evaluate the cost and effectiveness of ANP versus nab-paclitaxel in the first-line treatment of metastatic TNBC. Lifetime costs, life-years (LYs) and quality-adjusted LYs (QALYs) were estimated. Results: ANP provided an additional 0.16 QALYs (0.24 LYs) compared with nab-paclitaxel in intention-to-treat population. The corresponding incremental cost–effectiveness ratio was $786,131 per QALY gained. However, the incremental cost–effectiveness ratio decreased to $361,218 per QALY gained in the PD-L1 positive subgroup analysis. Conclusion: From the perspective of a US-payer, ANP is estimated not to be cost-effective in the first-line treatment of metastatic TNBC.
