Octapharma presents new data at ISTH 2023 in an ongoing commitment to improve the lives of people with bleeding disorders

• Octapharma to present new clinical and scientific findings for wilate^®, Nuwiq^®, octaplex^® and atenativ^® at the upcoming ISTH 2023 Congress

• New data and clinical study developments will be presented in nine posters and during two Supported Symposia

The most recent developments from Octapharma’s Haematology and Critical Care portfolios will be presented at the 31^st Congress of the International Society on Thrombosis and Haemostasis (ISTH) on June 24–28, 2023, in Montréal, Canada. The data will be featured in nine poster presentations and two Supported Symposia during this key international meeting. Octapharma is a proud Silver Supporter of the ISTH 2023 Congress. There will also be a promotional booth focusing on modern approaches to bleeding and coagulation management.

People with inherited bleeding disorders, such as haemophilia A and von Willebrand disease, are at risk of recurrent and prolonged bleeds placing a heavy burden on patients’ lives. In addition to the risk of potentially life-threatening bleeds, increased bleeding is associated with long-term consequences that severely impair patients’ quality of life.

Patients with a deficiency of the prothrombin complex of coagulation factors are also at increased risk of bleeding. Such deficiencies may be inherited but can also be acquired and may be induced by the use of vitamin K antagonists (VKA) for anticoagulation therapy. During urgent surgery, rapid correction of the deficiency is required and can be achieved through the use of four-factor prothrombin complex concentrates (4F-PCC). 4F-PCC can also be used to control major bleeding associated with the use of direct oral anticoagulant (DOAC) therapy in patients with factor Xa inhibitors.

The presentations at ISTH 2023 reflect Octapharma’s long-term commitment to improving patient care and addressing unmet clinical needs.

“We are proud to showcase our new data and provide updates of studies from across Octapharma’s haematology and critical care portfolios at ISTH 2023,” said Olaf Walter, Board Member at Octapharma. “Despite advances in the field, people with bleeding and coagulation disorders still face considerable challenges surrounding bleed management. At Octapharma, we strive to address such challenges head-on with the goal to improve the day-to-day lives of patients.”

Poster Presentations

The WIL-31 study investigated the efficacy and safety of prophylaxis with wilate^® in patients with von Willebrand disease (VWD) of any gender with VWD type 1, type 2 (except 2N) or type 3. The results of the study show that wilate^® prophylaxis is highly effective at reducing the number of bleeds in children and adults, and provides compelling evidence to support the use of regular prophylaxis in patients with severe VWD. Further data on the efficacy and safety of wilate^® prophylaxis is being collected in the WIL-33 study in children under six years of age. The goals and design of this study will be presented.

Prophylaxis is already the standard of care for people with haemophilia A. The results of an indirect comparison show that fewer patients experienced bleeds when receiving personalised prophylaxis with Nuwiq^® rather than prophylaxis with a comparator factor VIII (FVIII) product. New data exploring differences in the binding of different recombinant FVIII products to platelets in vitro will be shared in a separate poster.

Although haemophilia A mainly affects males, female carriers may also have reduced levels of FVIII and be at increased risk of bleeding, especially during traumatic events such as surgery. Data from a retrospective case series of female haemophilia A carriers who were prescribed Nuwiq^® during surgery at the Bonn Haemophilia Centre will provide an insight into the effective treatment of females.

MOTIVATE is an ongoing, international investigator-initiated study made possible through funding from Octapharma AG, evaluating the management of haemophilia A patients with inhibitors. The Coordinating investigators, Drs Carmen Escuriola Ettingshausen and Robert F. Sidonio Jr., will provide an update on the study status as a poster at the Congress.

The LEX-210 study will evaluate the haemostatic efficacy of octaplex^® in patients with acute major bleeding receiving factor Xa inhibitors. As anti-factor Xa (anti-Xa) activity levels will be measured in these patients, the correlation between heparin-calibrated and specific factor Xa inhibitor assays has been analysed and will be presented.

The results from the first head-to-head, phase 3, randomised, controlled trial (LEX-209) comparing two 4F-PCCs in patients on VKA anticoagulation who need urgent surgery will be presented, with a focus on dosing and haemostatic efficacy results. The results show that octaplex^® was non-inferior to control 4F-PCC for rapid vitamin K antagonist reversal in patients undergoing urgent surgeries with significant bleeding risk.

The posters will be presented at the following times:

  Monday June 26, 13:15–14:30 ET, Room 511
  Chair: Alok Srivastava, Christian Medical College, Vellore, India
  
  The symposium will focus on new data regarding the use of wilate^® prophylaxis in children and adults to improve the lives of people with VWD. Topics presented will include the importance of prophylaxis, including current guidelines on the management of VWD and how to identify patients who may benefit from prophylactic treatment. Key learnings from the WIL-31 VWD prophylaxis study will be shared and case presentations of select WIL-31 patient cases from across the globe will be discussed.

  Octapharma’s symposium on haemophilia A this year is dedicated to both, scientists and clinicians. The speakers will present data from the NuPreviq trial and the matching adjusted indirect comparisons (MAIC) analyses of Nuwiq^® vs extended half-life (EHL) products as well as introduce the PROVE study. Topics discussed during this symposium will also include the role of platelets in FVIII binding, impact of prophylaxis on microRNA expression (biomarkers of joint and bone health) and how to utilise the power of RNASeq to understand inhibitor development.

Both symposia will be open to congress participants in Montréal and will be streamed live for participants not attending the Congress. The opportunity to ask questions will be available at both symposia.

Larisa Belyanskaya, Head of IBU Haematology at Octapharma commented: “We are delighted to showcase new data from WIL-31, which supports the importance of prophylaxis in people with von Willebrand disease, and to discuss scientific and clinical questions that need to be address to advance the management of people with haemophilia A.”
