OSAKA, Japan--(뉴스와이어) 2020년 06월 15일 -- Takeda Pharmaceutical Company Limited, (“Takeda”) (TSE: 4502/NYSE:TAK) today announced a scientific update from the AHEAD real-world study investigating the long-term outcomes associated with ADVATE [antihemophilic factor (recombinant), rAHF] in patients with hemophilia A, presented as an oral presentation at the World Federation of Hemophilia Virtual Summit 2020 (WFH 2020). The update is one of the three abstracts being presented at WFH 2020 from Takeda’s Hematology portfolio and pipeline. Echoing Takeda’s theme at the virtual summit - “It’s Personal” - the company also shared data from a physician survey in China, providing insights into optimizing personalized care and hemophilia patient management in centers of excellence (COE).
“It’s Personal”: Takeda is relentless in its pursuit of a bleed-free world
“Takeda’s vision for a bleed-free world is as important today as ever,” commented Dr. med. Wolfhard Erdlenbruch, M.D., Vice President Head of Global Medical Affairs Hematology, Takeda. “The data we presented at WFH 2020 continue to add to the body of evidence for the management of hemophilia, a bleeding disorder that affects at least 210,000 people worldwide as of 2018 and potentially a lot more.[i,ii] As a leader in Hematology, Takeda is committed to improving patient outcomes, and the findings of our studies demonstrate the value personalized strategies can offer to patients as part of the ongoing management of their bleeding disorder.”
Prophylaxis for hemophilia A is the standard of care treatment for patients because it can help prevent spontaneous bleeds, as even a single bleed may cause joint damage and impact their quality of life.[iii,iv]
Interim analysis results from the AHEAD real-world outcomes study [abstract MED‐FP‐005 (363)] demonstrate that the number of hemophilia A patients who were able to achieve zero bleeds increased over the years by receiving rAHF. For those receiving prophylaxis, the number of patients with zero bleeds increased from 34% in year 1 to 53% in year 6. For those receiving on-demand treatment, it increased from 28% in year 1 to 38% in year 6. The results also show that those receiving rAHF prophylaxis generally reported slightly better health-related quality of life (HRQoL) than those receiving rAHF on-demand. The results support the role of rAHF as an important option for hemophilia A, a condition which requires life-long monitoring and management.[v]
“The results of the interim analysis from the AHEAD real-world outcomes study support the long-term effectiveness of rAHF for hemophilia A patients, which was maintained in a six-year observational period and bolstered by consistent HRQoL scores,” added Prof. Dr. med. Johannes Oldenburg, Chairman and Director, Institute of Experimental Haematology and Transfusion Medicine, University Clinic Bonn AöR, Germany, who is the researcher leading the study. “Every patient is unique, and these results support a tailored and personalized approach to optimize care for patients with bleeding disorders, delivered in partnership with their treating physician.”
Takeda aims to help advance more personalized, connected care for patients
Takeda presented two additional abstracts at WFH 2020 - available on the summit’s iPoster Gallery (within the ‘Open to all’ and ‘HCP’ sections respectively) - supporting its personalized care approach for patients with hemophilia.
· Multi-department collaboration for the management of hemophilia A[vi] [iPoster MTD-PO-057]
A substantial number of patients with hemophilia A live in China, due to the large population.i Results from a physician survey explored the Center of Excellence (COE) model for the optimization of multi-department collaboration for patients with hemophilia A in China; low patient awareness of the need for treatment/prophylaxis and fewer than 40% of patients received prophylaxis, demonstrated the need for improvements in both public and physician awareness and knowledge of hemophilia. Results showed that a COE model may improve collaboration across departments, optimize patient management and thereby improve outcomes.
· Real-world safety and effectiveness of Rixubis in patients with hemophilia B in South Korea[vii] [iPoster MED-PO-018]
Data from a prospective, post-marketing surveillance study evaluating the safety and efficacy profile of Rixubis [Nonacog gamma, recombinant FIX concentrate] demonstrated the safety and efficacy profile for bleeds, perioperative/surgery, and prophylaxis in adult and pediatric patients with hemophilia B in the real-world setting in South Korea. The study showed that 86.6% (123/142) of hemostatic effectiveness assessments for nonacog gamma were reported as good or excellent, and of the 11 adverse events reported, all were mild in severity, with 10 resolved/recovered events not related to nonacog gamma, and one event (inhibitory antibody development) unconfirmed.
“The findings presented at WFH 2020 highlight our commitment to patients living with bleeding disorders, and are adding to the bank of scientific evidence supporting the importance of personalized care in Hematology,” Dr. Erdlenbruch concluded. “In addition to the AHEAD study, results from the physician survey in China supported the rationale for cross-department collaboration to optimize patient care. All the results from WFH 2020 emphasize the importance of understanding each patient and offering tailored support for those with bleeding disorders who may have differing needs.”
ADVATE is a full-length (derived from the complete FVIII gene) recombinant FVIII product that is processed without any blood-based additives.

ADVATE SAFETY INFORMATION FOR EUROPE[viii]
Please consult the ADVATE Summary of Product Characteristics (SmPC) before prescribing, particularly in relation to dosing and treatment monitoring.
Hypersensitivity to the active substance or to any of the excipients listed in the SmPC or to mouse or hamster proteins.
Special warnings and precautions for use
The product contains traces of mouse and hamster proteins. If symptoms of hypersensitivity occur, patients should be advised to discontinue use of the product immediately and contact their physician.
Patients should be informed of the early signs of hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing, hypotension and anaphylaxis.
The formation of neutralising antibodies (inhibitors) to factor VIII is a known complication in the management of individuals with haemophilia A. These inhibitors are usually IgG immunoglobulins directed against the factor VIII procoagulant activity, which are quantified in Bethesda Units (BU) per mL of plasma using the modified assay.
In general, all patients treated with coagulation factor VIII products should be carefully monitored for the development of inhibitors by appropriate clinical observations and laboratory tests. If the expected factor VIII activity plasma levels are not attained, or if bleeding is not controlled with an appropriate dose, testing for factor VIII inhibitor presence should be performed.
After reconstitution this medicinal product contains 0.45 mmol sodium (10 mg) per vial.
Very common (≥1/10)
Factor VIII inhibition in previously untreated patients (PUPs)
Common (≥1/100 to <1/10)
Uncommon (≥1/1000 to <1/100)

RIXUBIS is an injectable medicine used to replace clotting factor IX that is missing in adults and children with hemophilia B.
RIXUBIS SAFETY INFORMATION FOR EUROPE[ix]
Please consult the RIXUBIS Summary of Product Characteristics (SmPC) here (https://bit.ly/3hwGvfl) before prescribing, particularly in relation to dosing and treatment monitoring.
Hypersensitivity to the active substance or to any of the excipients listed in the SmPC. Known allergic reaction to hamster protein.
Special warnings and precautions for use
In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.
Allergic type hypersensitivity reactions have been reported with RIXUBIS. The product contains traces of hamster proteins. If symptoms of hypersensitivity occur, patients or their caregivers should be advised to discontinue use of the medicinal product immediately and contact their physician. Patients should be informed of the early signs of hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing, hypotension, and anaphylaxis. The risk is highest during the early phases of initial exposure to factor IX concentrates in previously untreated patients (PUPs), in particular in patients with high-risk gene mutations. There have been reports in the literature showing an association between the occurrence of a factor IX inhibitor and allergic reactions, in particular in patients with a high-risk gene mutation. Therefore, patients experiencing allergic reactions should be evaluated for the presence of an inhibitor. In case of shock, standard medical treatment for shock should be implemented.
After repeated treatment with human coagulation factor IX (rDNA) products, patients should be monitored for the development of neutralising antibodies (inhibitors) that should be quantified in Bethesda Units (BU) using appropriate biological testing. There have been reports in the literature showing a correlation between the occurrence of a factor IX inhibitor and allergic reactions. Therefore, patients experiencing allergic reactions should be evaluated for the presence of an inhibitor. It should be noted that patients with factor IX inhibitors may be at an increased risk of anaphylaxis with subsequent challenge with factor IX. Because of the risk of allergic reactions with factor IX concentrates, the initial administrations of factor IX should, according to the treating physician’s judgement, be performed under medical observation where proper medical care for allergic reactions could be provided.
Nephrotic syndrome has been reported following attempted immune tolerance induction in haemophilia B patients with factor IX inhibitors.
Because of the potential risk of thrombotic complications, clinical surveillance for early signs of thrombotic and consumptive coagulopathy should be initiated with appropriate biological testing when administering this product to patients with liver disease, to patients post-operatively, to new-born infants, or to patients at risk of thrombotic phenomena or DIC. In each of these situations, the benefit of treatment with RIXUBIS should be weighed against the risk of these complications.
In patients with existing cardiovascular risk factors, substitution therapy with FIX may increase the cardiovascular risk.
If a central venous access device (CVAD) is required, risk of CVAD-related complications including local infections, bacteraemia and catheter site thrombosis should be considered.
Excipient related considerations
This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium free’. Depending on body weight and Posology of RIXUBIS, patients could receive more than one vial. This should be taken into consideration if the patient is on a controlled sodium diet.
Clinical studies of RIXUBIS did not include subjects aged 65 and over. It is not known whether they respond differently from younger subjects. As for all patients, dose selection for an elderly patient should be individualised.
The listed warnings and precautions apply both to adults and children.

Hemophilia is a chronic disease that causes longer-than-normal bleeding due to absent or deficient clotting factor in the blood.[x] Hemophilia A is more common than hemophilia B; in 2018, hemophilia A affects about 173,711 people, whereas hemophilia B affects about 34,289 people worldwide.[i]
People with hemophilia, working closely with their healthcare professionals, can live healthy lives with proper care and adequate treatment.[xi] Treatment regimens typically include on-demand and/or regular prophylactic infusions of factor replacement therapy to control or prevent the risk of bleeding.[xii]
