Takeda to Demonstrate Global Leadership in Hematology at ISTH 2019

Share

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
  • Preexisting immunity against AAV8 and other AAV serotypes in healthy individuals and patients with hemophilia B.
    • 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

Gilead Presents New Data on Biktarvy® for the Treatment of HIV in Women and in Virologically Suppressed Patients With Known Resistance22.7.2019 16:00:00 CESTPress release

Gilead Sciences, Inc. (NASDAQ: GILD) today presented findings from two Phase 3 trials – a trial demonstrating the effectiveness of switching to Biktarvy (bictegravir 50mg/emtricitabine 200mg/tenofovir alafenamide 25mg tablets, B/F/TAF) in women, and a trial evaluating the potential for the single tablet regimen to be an effective treatment option in virologically suppressed patients with known resistance to nucleo(s)tide or non-nucleo(s)tide reverse transcriptase inhibitors (NRTIs or NNRTIs). The use of Biktarvy in patients with known drug resistance is investigational. These data were presented at the 10th International AIDS Society Conference on HIV Science (IAS 2019) being held in Mexico City. “These data presented at IAS provide new information about the treatment of HIV among women and patients with known drug resistance,” said Diana Brainard, MD, Senior Vice President, HIV and Emerging Viruses, Gilead Sciences. “The studies further demonstrate the potential for Biktarvy to be an

IBC Celebrates Young Talent in the Industry22.7.2019 15:36:00 CESTPress release

Gilead Presents Proof-of-Concept Data for GS-6207, a First-in-Class Capsid Inhibitor, in People Living With HIV22.7.2019 15:00:00 CESTPress release

Gilead Sciences, Inc. (NASDAQ: GILD) today presented the first clinical data in people living with HIV on GS-6207, an investigational, novel, selective, first-in-class inhibitor of HIV capsid function. The Phase 1b data demonstrate the first proof of concept that HIV capsid inhibition can lead to significant declines in viral load in vivo. In addition, Gilead presented preclinical data demonstrating that resistance to GS-6207 in vitro did not lead to resistance to other classes of drugs used in the treatment of HIV. These data were presented at the 10th International AIDS Society Conference on HIV Science (IAS 2019) in Mexico City. GS-6207 is an investigational long-acting antiretroviral agent that can be delivered subcutaneously. GS-6207 recently received breakthrough therapy designation from the U.S. Food and Drug Administration (FDA) as a potential therapy for heavily treatment-experienced people living with multi-drug resistant HIV. GS-6207 acts in a novel way compared with current
