Cost-effectiveness analysis of durvalumab with chemotherapy and maintenance durvalumab with or without olaparib for advanced endometrial cancer.

ABSTRACT: This study evaluates the cost-effectiveness of adding durvalumab to chemotherapy, with subsequent maintenance either with olaparib (DOCT) or without olaparib (DCT), versus chemotherapy alone (CT) as a first-line treatment for advanced endometrial cancer (EC) in the United States, stratified by mismatch repair deficiency (dMMR) and proficiency (pMMR). A Markov model based on DUO-E Phase III trial data simulated disease progression and outcomes. Total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICER) were evaluated. Sensitivity analysis assessed model robustness. For dMMR EC, costs (QALYs) were $1,204,763.33 (5.49), $590,732.13 (4.61), and $1,495,528.15 (3.68) for DOCT, DCT, and CT, respectively, with ICER of $584,140.94/QALYs (DOCT vs. CT) and $476
