Background:
Although lecanemab has demonstrated clinical efficacy in early Alzheimer's disease (AD), its cost-effectiveness in China remains uncertain. This study evaluated the long-term cost-effectiveness of lecanemab in Chinese patients from a societal perspective and estimated its value-based price (VBP).
Methods:
A Markov state transition model based on Chinese real-world data was developed to compare the long-term health progression and economic outcomes of lecanemab combined with standard of care (SoC) versus SoC alone.
Results:
Compared to SoC alone, the lecanemab combination therapy gained an additional 1.2432 Quality-adjusted life years (QALYs) at an incremental cost of 463,228 Chinese yuan (CNY), resulting in an incremental cost-effectiveness ratio (ICER) of 372,609 CNY/QALY (≈ 52,783 USD/QALY). To achieve cost-effectiveness within the willingness-to-pay threshold, the price of a single vial of lecanemab must be reduced by at least 18.0%.
Discussion:
Lecanemab can provide health benefits to Chinese patients with early AD, but it is not cost-effective under the current pricing system.
