Takeda to Demonstrate Global Leadership in Hematology at ISTH 2019

Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (“Takeda”), the global biotechnology leader in rare diseases, will present research covering a broad range of rare bleeding disorders at the 27th Annual International Society on Thrombosis and Haemostasis Congress (ISTH), July 6-10, 2019 in Melbourne, Australia. Showcased in 10 oral presentations and 38 poster presentations, these data underscore Takeda’s pursuit of treatment innovation to achieve optimized and personalized patient care in hematology.

“At Takeda, we are proud of the hematology heritage Shire, Baxalta and Baxter built over 70 years and we plan on expanding on it through continued research and innovation, in pursuit of a world without bleeds,” said Dr. med. Wolfhard Erdlenbruch, Vice President Head of Global Medical Affairs Hematology, Takeda. “We look forward to presenting new data from PROPEL and important updates from our gene therapy and leading factor pipeline at ISTH 2019, showcasing our continued development and commitment in this area.”

Importance of personalized prophylaxis in haemophilia
At ISTH 2019, Takeda will unveil new data from the Phase IIIb/IV PROPEL study – a PROspective, randomized, multi-center study comparing the safety and efficacy of ADYNOVATE following PK-guided prophylaxis targeting two different Factor Eight (FVIII) trough Levels in subjects with severe hemophilia A.¹ This data will build on results presented at the European Association of Haemophilia and Allied Disorders (EAHAD) 2019,² to provide important insights into the role of personalized prophylaxis for enabling improved patient outcomes and bleed protection, in people living with hemophilia A.¹

• PK-guided rurioctocog alfa pegol prophylaxis in patients with severe hemophilia A targeting two FVIII trough levels: results from the phase 3 PROPEL Study.
  • Hemophilia Optimizing Prophylaxis, ABSTRACT #OC 42.1; Monday, 08 July 2019, 14:45-16:00, Melbourne Room 2

Advancing the Promise of Gene Therapy in Hemophilia
Takeda will also present 14 scientific updates regarding its gene therapy pipeline for both hemophilia A and B. The goal of gene therapy is to enable a hemophilia patient’s body to naturally produce a sufficient amount of the missing factor VIII or IX to alleviate bleeding episodes.³ Therefore, it may be possible to help convert a hemophilia patient’s bleeding phenotype from severe to mild or even normal in some cases.⁴ Takeda’s TAK-754 is our AAV FVIII gene therapy vector currently under investigation in a Phase I/II trial.

Notably, Takeda will showcase the following gene therapy data, in oral presentations:

• Nonclinical pharmacology of TAK-748/SHP648 a novel factor IX (FIX) gene therapy vector in mice and rhesus monkeys.
  • Gene Therapy Basic 1; Oral #OC 22.1 ; Sunday, 07 July 2019, 14:45-16:00, Melbourne Room 1

  • Gene Therapy Basic 2; Oral #OC31.4; Monday, 08 July, 2019, 10:45-12:00, Melbourne Room 1

• Whole exome sequencing of patients treated with adeno-associated virus serotype 8-factor IX (AAV8-FIX) gene therapy (BAX335) reveals potential determinants of persistent transgene expression.
  • Gene Therapy Basic 2; Oral #31.1; Monday, 08 July, 2019, 10:45-12:00, Melbourne Room 1

• CTLA-4 IgGs - a powerful tool to enable re-administration in AAV8 gene therapy and to suppress anti-AAV8 T cell responses.
  • Gene Therapy Basic 2; Oral #31.2; Monday, 08 July, 2019, 10:45-12:00, Melbourne Room 1

About Hemophilia
Hemophilia is a challenging chronic disease that causes longer-than-normal bleeding due to absent or deficient clotting factor in the blood.⁵ Hemophilia A is more common than hemophilia B;⁵ hemophilia A affects about 150,000 people, whereas hemophilia B affects about 30,000 people worldwide.⁶

People with hemophilia, working closely with their healthcare professionals, can live healthy lives with proper care and adequate treatment.⁷ Treatment regimens typically include on-demand and/or regular prophylactic infusions of factor replacement therapy to control or prevent the risk of bleeding.^5,8
