This paper aims to provide a comprehensive reviewof the rationale for developing EHL coagulation factors and theirutility in the management of hemophilia, with special emphasis onoptimal techniques for half-life extension and criteria for definingEHL coagulation factors, as well as indications, efficacy, and safetyissues of the currently available EHL-rFVIII and EHL-rFIX products.Potential impacts of these factors on quality of life, health economics,and immune tolerance treatment will also be discussed alongside thechallenges in pharmacokinetic-driven prophylaxis and difficulties inmonitoring the EHL products with laboratory assays.

Abstract

Despite effective factor replacement and various treatment schedules,there remain several challenges and unmet needs in the prophylactictreatment of hemophilia limiting its adoption and thereby posingan increased risk of spontaneous bleeding. In this regard, extendedhalf-life (EHL) recombinant factor VIII (rFVIII) and factor IX (rFIX)products promise optimal prophylaxis by decreasing the dosefrequency, increasing the compliance, and improving the quality oflife without compromising safety and efficacy. EHL products mightlead to higher trough levels without increasing infusion frequency, orcould facilitate the ability to maintain trough levels while reducinginfusion frequency. This paper aims to provide a comprehensive reviewof the rationale for developing EHL coagulation factors and theirutility in the management of hemophilia, with special emphasis onoptimal techniques for half-life extension and criteria for definingEHL coagulation factors, as well as indications, efficacy, and safetyissues of the currently available EHL-rFVIII and EHL-rFIX products.Potential impacts of these factors on quality of life, health economics,and immune tolerance treatment will also be discussed alongside thechallenges in pharmacokinetic-driven prophylaxis and difficulties inmonitoring the EHL products with laboratory assays.

Özet

Etkin faktör yerine koyma tedavisi ve değişik tedavi programlarına rağmen günümüzde hemofilinin profilaktik tedavisinde hala çözülmemiş sorunlar ve karşılanmamış gereksinimler vardır. Bu nedenle kanama riski ve kanamaya bağlı komplikasyonlar önemini korumaktadır. Bu bağlamda profilakside kullanılacak uzatılmış yarı ömürlü rekombinant faktör VIII ve faktör IX ürünleri tedavinin güvenlilik ve etkililiğinden ödün vermeksizin doz sıklığının azaltılması, hasta uyumunun artması ve yaşam kalitesinin düzelmesini sağlayarak optimal tedavi koşullarının oluşmasına yardımcı olabilir. Uzatılmış yarı ömürlü faktörler infüzyon sıklığını artırmadan daha yüksek çukur değerler ulaşılması veya mevcut çukur değerin daha seyrek infüzyonla idamesi konusunda önemli bir açılım sağlayabilir. Bu derlemede uzatılmış yarı ömürlü faktör konsantrelerinin geliştirilmesine neden gerek duyulduğu, hemofili tedavisindeki olası yerleri, faktör yarı ömrünü uzatmak için kullanılan teknikler ve mevcut uzatılmış yarı ömürlü faktör konsantrelerinin etkililik, güvenlilik ve endikasyonları ile ilişkili kapsamlı bilgi sunulacaktır. Ayrıca bu ürünlerin yaşam kalitesi ve sağlık ekonomisi üzerine etkileri, immün tolerans tedavisindeki yerleri, farmakokinetik temelli profilaside kullanımları ile laboratuvar izleminde karşılaşılan güçlükler tartışılacaktır.
