Extended half-life Factor VIII (FVIII) products significantly reduce infusion frequency in haemophilia A patients. These advanced treatments maintain effective bleeding control, improving patient adherence and quality of life.
Area of Science:
- Hematology
- Pharmacology
- Clinical Medicine
Background:
- Haemophilia A is a genetic bleeding disorder requiring Factor VIII (FVIII) replacement therapy.
- Prophylactic FVIII treatment is crucial for preventing joint damage and improving quality of life.
- Extended half-life (EHL) FVIII products offer advancements in treatment frequency, efficacy, and safety.
Purpose of the Study:
- To evaluate the real-world utilization and effectiveness of FVIII products.
- To compare pharmacokinetic profiles and infusion frequencies of EHL FVIII products versus standard half-life (SHL) products.
- To assess bleeding control and treatment burden in patients receiving EHL FVIII therapy.
Main Methods:
- A single-centre observational study conducted from January 2018 to December 2023.
- Involved 124 male patients treated at the Haemophilia Centre of Padua.
- Analysis of patient characteristics, treatment regimens, and pharmacokinetic data.
Main Results:
- Esperoct® demonstrated the longest median half-life (19.75 hours), followed by Elocta® (16.50 hours) and Jivi® (15.38 hours).
- EHL FVIII products resulted in significantly lower weekly infusion rates (1.4) compared to SHL products (2.0) (p < 0.001).
- Comparable bleeding control was observed across different EHL FVIII products.
Conclusions:
- EHL FVIII products provide substantial clinical benefits by reducing infusion burden and enhancing adherence.
- Effective bleeding control is maintained with EHL FVIII therapies.
- Further research on cost, safety, and long-term outcomes is necessary for optimal integration into haemophilia care.
