We evaluated the stage-specific cost-effectiveness of tafamidis in Japan.</p><p><strong>Methods and results: </strong>Individual patient-level data were reconstructed from published Kaplan-Meier curves from the ATTR-ACT long-term extension study. Time-dependent survival benefit between early (continuous tafamidis) and delayed (placebo-to-tafamidis) tafamidis initiation was quantified using restricted mean survival time (RMST). Stage-specific incremental cost-effectiveness ratios (ICERs) were estimated according to National Amyloidosis Centre (NAC) stage. Drug costs reflected the official Japanese reimbursement price, and quality-adjusted life years (QALYs) were derived from RMST gains. The primary endpoint was cardiovascular mortality. At maximum follow-up, RMST gains were 15.7, 13.1, and 1.2 months in NAC stage I, II, and III, respectively ICERs declined over time but remained above commonly accepted Japanese willingness-to-pay thresholds (5,000,000-15,000,000 yen/QALY). The lowest ICER was 47,000,000 yen/QALY in NAC stage I at 90 months. Sensitivity analyses showed that results were robust across utility assumptions, whereas drug cost was the principal determinant of cost-effectiveness.</p><p><strong>Conclusions: </strong>The survival benefit and economic value of tafamidis varied by disease stage.
