MedicalResearch.com Interview with: Prof. Dr. med. Johannes Oldenburg Chairman and Director Institute of Experimental Haematology and Transfusion Medicine University Clinic Bonn AöR, Germany  MedicalResearch.com: What is the background for this study? Response: 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.1,2 The Antihemophilic factor (recombinant) (rAHF) Hemophilia A (HA) outcome Database (AHEAD) study, which has been running for 6 years, evaluates long-term, real-world outcome data on effectiveness, safety and joint health in patients with hemophilia A who are receiving rAHF (ADVATE®) and ADYNOVI.  (more…)

MedicalResearch.com Interview with: TakedaDr. med. Wolfhard Erdlenbruch, M.D. Vice President Head of Global Medical Affairs Hematology MedicalResearch.com: What is the background for this study? Response: At the World Federation of Hemophilia Virtual Summit 2020 (WFH 2020), results were presented from a real-world, post-marketing surveillance study aimed to evaluate the safety and effectiveness of RIXUBIS® in adult and pediatric patients with hemophilia B in South Korea, entitled “Safety and Effectiveness of Rixubis in Patients with Hemophilia B in South Korea: A Real-World, Prospective, Post-marketing Surveillance Study”. Data from the study demonstrate the safety and efficacy profile of RIXUBIS® for treatment of 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 RIXUBIS® 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 RIXUBIS®, and one event (inhibitory antibody development) unconfirmed.1 RIXUBIS® [Nonacog gamma, recombinant FIX concentrate] is a recombinant coagulation factor IX product, indicated for the control and prevention of bleeding episodes in patients with hemophilia B.

MedicalResearch.com Interview with: Dr. Johnny Mahlangu  MBBCh Faculty of Health Sciences University of the Witwatersrand and National Health Laboratory Service Johannesburg, South Africa MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current unmet needs in patients with haemophilia without inhibitors are the high disease burden imposed by the frequent injections which have to be given intravensously . Emicizumab which is given subcutaneously weekly or fortnightly aims to address these unmet needs. (more…)

MedicalResearch.com Interview with: Stephanie Seremetis, M.D. Corporate Vice President and Chief Medical Officer Biopharmaceuticals at Novo Nordisk MedicalResearch.com: What is the background for this announcement? Response: We’re proud and excited to make Rebinyn® (Coagulation Factor IX (Recombinant), GlycoPEGylated) available as a new extended half-life treatment for hemophilia B management. Rebinyn® is an injectable medicine used to treat and control bleeding in adults and children with hemophilia B. It can be used to treat bleeds when they occur and to manage bleeding during surgery. Rebinyn® is not used for routine prophylaxis or for immune tolerance induction in patients with hemophilia B. Hemophilia B is a serious, chronic, inherited bleeding disease that affects about 5,000 people in the U.S. People living with hemophilia B have low levels of clotting Factor IX protein in the blood, often resulting in prolonged or spontaneous bleeding, especially into the muscles, joints or internal organs.  (more…)

MedicalResearch.com Interview with: Dr. Charles T. Nakar, MD Indiana Hemophilia and Thrombosis Center Pediatrics Indianapolis, IN   MedicalResearch.com: What is the background for this study? Response: Congenital plasminogen deficiency is a rare genetic disorder that is caused by mutations in the PLG gene. Mutations in this gene lead to clinical manifestations such as fibrinous deposits on mucous membranes leading to disruption of tissue or organ function. These symptoms, when untreated, lead to significant morbidity and decreased quality of life. Life-threatening episodes may occur especially when the respiratory system is affected. There is currently no established approach to treatment of type 1 plasminogen deficiency and the available topical and systemic therapies (e.g. FFP, corticosteroids, immunomodulatory drugs, anticoagulants, amongst others) lack consistent efficacy. Patients may undergo multiple surgeries to remove lesions, but this approach typically leads to regrowth of lesions. Prometic’s intravenous plasminogen replacement therapy represents the first direct treatment for this serious disorder. (more…)

MedicalResearch.com Interview with: Jerry Powell MD Medical Director North America Commercial Operations CSL Behring MedicalResearch.com: What is the background for this study? Response: The new IDELVION results presented at the American Society of Hematology (ASH) are from a pooled analysis of clinical studies from the global PROLONG-9FP clinical development program. The analysis assessed the relationship between estimated factor IX activity levels and clinical bleeding risk in adult hemophilia B patients treated with IDELVION using prophylaxis or on-demand (episodic) treatment. The PROLONG-9FP clinical development program included five Phase I through Phase III open-label, multicenter studies evaluating the pharmacokinetics, safety and efficacy of IDELVION in children and adults with hemophilia B.

MedicalResearch.com: Nisha Jain, Director Global Medical at Biogen Regarding: Post Hoc Analysis to Evaluate the Effect of Recombinant Factor IX Fc Fusion Protein (rFIXFc) Prophylaxis in Adults and Adolescents with Target Joints and Hemophilia B being presented at the World Federation of Hemophilia (WFH) 2016 World Congress MedicalResearch.com: What is the background for this study? Response: People with hemophilia B experience prolonged bleeding episodes that can cause pain, irreversible joint damage and life-threatening hemorrhages. For people with severe hemophilia, most bleeding events occur in joints, with joint damage being the most common complication of the condition.(1) Over time, joints can become severely damaged and an individual can suffer from acute pain as well as restricted range of motion in those joints.(1) MedicalResearch.com: What are the main findings? Response: The B-LONG and B-YOND trials evaluated ALPROLIX® [Coagulation Factor IX (Recombinant), Fc Fusion Protein] in hemophilia B patients. In this post-hoc analysis of 37 patients with target joints in B-LONG and B-YOND, most (98.9%) target joints were considered resolved using the International Society on Thrombosis and Haemostasis (ISTH) definition of resolution as ≤ 2 bleeds into the joint within a consecutive 12-month period.

MedicalResearch.com Interview with: Dr. Elena Santagostino, MD PhD Angelo Bianchi Bonomi Hemophilia and Thrombosis Center Ca' Granda Foundation Maggiore Hospital Policlinico, Milan, Italy Medical Research: What is the background for this study? What are the main findings? Dr. Santagostino: Two of our abstracts presented at the 57th ASH Annual Meeting are part of the PROLONG-9FP clinical program evaluating the efficacy and safety of CSL Behring’s investigational long-acting fusion protein linking recombinant coagulation factor IX with recombinant albumin (rIX-FP).  The first is an oral presentation on results from two Phase III studies and an ongoing extension study of rIX-FP for routine prophylaxis in previously-treated people with hemophilia B. The two Phase III studies included adolescents and adults (ages 12 to 61) treated with dosing intervals of up to 14 days for 12 to 18 months, and children (ages 1 to 11) who received seven-day prophylaxis treatment for approximately 12 months. Overall, the median annualized spontaneous bleeding rate (AsBR) was 0.00 for all treatment intervals. The extension study is examining longer treatment intervals, including 10- and 14-day intervals in patients younger than 12 and more prolonged treatment intervals in patients older than 18, and so far has reported favorable long-term tolerability with no serious adverse reactions such as the development of inhibitors to factor IX or antibodies to rIX-FP. A second abstract reported on a surgical sub-study in these trials found that a single pre-operative dose of rIX-FP maintained hemostasis during surgery with responses rated by investigators as “excellent” or “good.” Oven a 14-day perioperative period, patients needed six or seven infusions, and none developed inhibitors to factor IX or antibodies to rIX-FP.
