U.S. FDA Accepts for Review CSL Behring’s BLA for its Novel rVIII-SingleChain Therapy for Patients with Haemophilia A

Melbourne, Australia — 28/07/2015

CSL Limited (ASX:CSL; USOTC: CSLLY) announced today that the U.S. Food and Drug Administration (FDA) has accepted for review CSL Behring’s Biologics License Application (BLA) for its novel investigational recombinant factor VIII single-chain (rVIIISingleChain) for the treatment of haemophilia A. In the pivotal clinical trial, rVIIISingleChain met all primary endpoints.

Haemophilia A is a congenital bleeding disorder characterized by deficient or defective factor VIII. People with haemophilia A may experience prolonged or spontaneous bleeding, especially into the muscles, joints, or internal organs. The condition affects approximately 1 in 6,000 male births.

“CSL Behring has one of the industry’s largest portfolios of biotherapies that improve the care and well-being of patients with a bleeding disorder,” said Dr. Andrew Cuthbertson, Chief Scientific Officer and Director of R&D, CSL Limited. “Our scientific expertise and relationship with the bleeding disorders community led us to seek further advancements in the care and treatment of haemophilia. Today, we have the only recombinant singlechain factor VIII product in late-stage development for the management of haemophilia A and we are excited to be one step closer to providing this innovative treatment to patients in the U.S.”

The BLA submission is based on the AFFINITY clinical development program, which includes a phase I/III open-label, multi-center trial examining safety and efficacy. The pharmacokinetics of rVIII-SingleChain compared with recombinant human antihaemophilic factor VIII (octocog alfa) was also studied. Study design details for rVIIISingleChain are available at clinicaltrials.gov.
