Patient and Clinical Experience on Concizumab Clinical Trial: A Case Study (ASH 2024) - P=N/A, P3 | "The maintenance dose was initiated on week 4 based on a concizumab exposure of 97.9 ng/mL.Prior to explorer8, the patient was intensely treated with daily BeneFIX® and Rebinyn® prophylaxis during explorer6, but both FIX standard and extended half-life treatment failed to prevent bleeding episodes.Key Clinical Question : What factors should be considered when determining whether a patient should be withdrawn from a clinical trial?Clinical Approach : Throughout the clinical trial, the investigator discussed withdrawal from the study because of an increase in the number of bleeding episodes; however, the patient remained in the clinical trial as the patient and their family preferred concizumab over previous prophylaxis regimens. This case demonstrates that we may have more to learn from our patients on why they choose to participate and/or stay on clinical trials.Disclaimer : Novo Nordisk had no influence on the content of the ABSTRACT .

Comparing Real-World Outcomes of Prophylaxis with Extended Half-life Factor IX (rIX-FP vs. rFIXFc and N9-GP) for Haemophilia B: An Analysis of Medical Chart Data from Germany. (PubMed, Adv Ther) - "rIX-FP prophylaxis was associated with significantly lower FIX consumption and numerically (but not significantly) lower bleeding rates compared with rFIXFc. Compared to N9-GP, prophylaxis with rIX-FP was associated with similar FIX consumption and significantly lower bleeding rates."

REAL-WORLD EXPERIENCE WITH NONACOG BETA PEGOL IN HEMOPHILIA B AFTER 30 MONTHS OF FOLLOW-UP (EHA 2025) - "A retrospective review of the medical records of two patients who switched from SHL to EHL FIX was conducted to assess their clinical outcomes and therapeutic response.Patient 1 (46 years old, 72 kg): Previously on prophylaxis with Nonacog Alfa (SHL) at 4,000 IU twice weekly. Prophylactic therapy is highly effective in reducing bleeding episodes and their long-term complications, especially in patients with severe factor deficiency or a bleeding phenotype.Treatment should be individualized, considering the risk/benefit ratio alongside patient values and preferences, to determine the optimal timing and choice of prophylaxis.Recombinant factor products are a safe and effective treatment option for patients with .The availability of extended half-life factor IX products offers substantial prolongation of half-life, improving patient quality of life, reducing infusion frequency, and enhancing treatment adherence.Significant economic impact is observed, with a reduction in..."
