Cost-effectiveness of Enasidenib versus conventional care for older patients with IDH2-mutant refractory/relapsed AML.
In the randomized phase III IDHENTIFY trial, the IDH2 inhibitor enasidenib (ENA) showed improvement in event-free but not overall survival compared with conventional care regimens (CCR) among patients with relapsed/refractory (R/R), IDH2-mutant AML. We constructed a partitioned survival model to evaluate the cost-effectiveness of enasidenib for the treatment of older patients with R/R, and IDH2-mutant AML. In the base-case scenario, ENA exhibited an incremental effectiveness of 0.234quality-adjusted life-years (QALYs) compared to CCR, and an incremental cost of $126,800, leading to an incremental cost-effectiveness ratio of $540,300/QALY(95% CI: $197,800-$4,777,000/QALY). In probabilistic sensitivity analysis, CCR was favored in 99.8% of simulations. The cost of ENA would need to be decreased by 72% to be cost-effective at a willingness-to-pay threshold of $150,000/QALY. Our findings suggest that ENA is unlikely to be a cost-effective treatment for older patients with IDH2-mutant R/R AML under current pricing.
期刊介绍：
Leukemia & Lymphoma in its fourth decade continues to provide an international forum for publication of high quality clinical, translational, and basic science research, and original observations relating to all aspects of hematological malignancies. The scope ranges from clinical and clinico-pathological investigations to fundamental research in disease biology, mechanisms of action of novel agents, development of combination chemotherapy, pharmacology and pharmacogenomics as well as ethics and epidemiology. Submissions of unique clinical observations or confirmatory studies are considered and published as Letters to the Editor
