Sobi and Biogen receive positive opinion from CHMP for Alprolix (rFIXFc) for the treatment of hemophilia B

If approved, Alprolix would be among the first therapies in the European Union (EU) to offer people living with hemophilia B prolonged protection against bleeding episodes with prophylactic dosing intervals.

“This positive opinion marks an important step in our efforts to bring treatment innovation to people with hemophilia in Europe and around the world,” said Krassimir Mitchev, vice president and medical therapeutic area head of Haemophilia at Sobi. “We are already seeing the benefits that Fc fusion technology can offer through our recent EU launch of Elocta for people with hemophilia A. We are excited at the prospect of also offering the possibility for prolonged protection and reduced treatment burden to the hemophilia B community with Alprolix.”

The positive opinion was based on results from two global, Phase III clinical trials that demonstrated the efficacy, safety and pharmacokinetics of Alprolix for hemophilia B: the pivotal B-LONG study for previously treated adults and adolescents, and the Kids B-LONG study for previously treated children under age 12. The CHMP's recommendation is now referred to the European Commission (EC), which grants marketing authorisation for medicines in the EU.

“Therapies that offer prolonged protection from bleeds are changing the way many approach treatment of hemophilia,” said Gilmore O’Neill, senior vice president, Drug Innovation Units at Biogen. “We are proud to work with Sobi to continue bringing to Europe these innovative Fc fusion therapies, which are grounded in the most robust real-world experience of any prolonged circulation factor therapies to date.”

Sobi and Biogen are collaborators in the development and commercialisation of Alprolix for hemophilia B. Sobi has final development and commercialisation rights in the Sobi territory (essentially Europe, North Africa, Russia and most Middle Eastern markets). Biogen leads development and manufacturing for Alprolix and has commercialisation rights in North America and all other regions in the world excluding the Sobi territory.
