CSL Behring Delivers on its Promise to Advance Bleeding Disorder Treatment Research by Supporting 16 Data Presentations at ISTH 2019

Novel real world evidence for AFSTYLA® and IDELVION® to be highlighted

MELBOURNE,Australia,July 2,2019 -- Global biotherapeutics leader CSL Behring announced today that the company will support the presentation of new data from its recombinant coagulation factor programs at this year's International Society on Thrombosis and Haemostasis (ISTH) Congress in Melbourne,6-10,July,2019. In addition to supporting 15 posters and one oral presentation,the company will also host two satellite symposiums during the meeting. The ISTH congress presents an opportunity for leaders in hematology and thrombosis research to exchange new findings and discuss advances in patient care.

"Real world evidence can provide deep new insights that complement data acquired in clinical trials and can unlock the promise of novel bleeding disorder treatments",said Andrew Cuthbertson,Chief Scientific Officer and R&D Director,CSL Limited. "These presentations demonstrate our commitment to improving treatments and will provide valuable understanding to patients and physicians when creating a care plan."

Seven poster presentations,an oral presentation and a satellite symposium will add to the growing body of evidence demonstrating the safety and efficacy ofAFSTYLA® [Antihemophilic Factor (Recombinant),Single Chain].AFSTYLA(also known as rVIII-SingleChain),CSL Behring's recombinant factor VIII single-chain therapy for haemophilia A,is approved in over 40 countries including Australia,Japan,the European Union,United States,and Switzerland.

Five posters and a satellite symposium will highlight newIDELVION®[Coagulation Factor IX (Recombinant),Albumin Fusion Protein] data.IDELVION(also known as rIX-FP),CSL Behring's long-acting recombinant factor IX albumin fusion protein for haemophilia B,United States and Switzerland.
