To conduct a comprehensive clinical evaluation of albutrepenonacog alfa (rIX-FP) for the treatment of hemophilia B.
Based on guidelines, literature, and publicly available data, and following the PICOS principle, rIX-FP was compared with plasma-derived FIX, standard half-life recombinant FIX (SHL rFIX), and extended half-life recombinant FIX (EHL rFIX) across five dimensions: efficacy, safety, suitability, innovation, and economy.
The evaluation results indicate that rIX-FP has potential advantages over other FIX preparations in terms of reducing the annualized bleeding rate, increasing the proportion of patients with zero bleeding events, and improving joint health, with consistent trends observed in the pediatric subgroup. The safety profile of rIX-FP is comparable to that of other recombinant FIX preparations, with no unmanageable safety risks observed. Regarding suitability, rIX-FP is available in five dosage specifications, offers flexible dosing options, and requires no special storage conditions. In terms of innovation, it utilizes albumin fusion technology to extend the half-life, thereby reducing dosing frequency and increasing trough levels. As for economy, although not yet marketed in China, international data suggest that long-term treatment (≥3 years) with rIX-FP has a cost advantage compared to SHL rFIX and rFIXFc.
Based on available evidence, rIX-FP demonstrates certain clinical advantages in the treatment of hemophilia B. However, head-to-head comparative studies and local pharmacoeconomic evaluations are still warranted.
