Novo Nordisk has issued a notice warning healthcare professionals that the hemophilia B treatment Rebinyn (nonacog beta pegol, or N9-GP) can interfere with some laboratory tests that measure blood coagulation. Following reports that people with severe COVID-19 may develop a blood-clotting condition similar to…

Blood levels of two proteins — C-reactive protein (CRP) and vascular endothelial growth factor (VEGF) — involved in inflammation and blood vessel formation are significantly associated with, and may help predict, acute bleeding in the joints of people with severe hemophilia A, a study has found. The study,…

Genentech has issued a notice reminding healthcare professionals that its hemophilia A treatment Hemlibra (emicizumab) can interfere with some laboratory tests that measure blood coagulation. In the event that hemophilia patients on Hemlibra become infected with COVID-19, the company warns that not all tests will…

After receiving guidance from both the U.S. Food and Drug Administration and the European Medicines Agency, Catalyst Biosciences is preparing to launch a pivotal Phase 3 clinical trial assessing marzeptacog alfa activated (MarzAA) for the treatment of bleeding episodes in people hemophilia A or B with…

Patient treatment for hemophilia B has come a long way since the introduction of factor IX (FIX) concentrates. In a recent commentary published in the journal Blood and titled “A new era for hemophilia B treatment,” researchers from Oregon Health and Science University and Bloodworks Northwest highlighted recent advances in…

Hemophilia A patients who receive replacement therapies of factor VIII often develop inhibitors against factor concentrates which hinders the effectiveness of the therapy, increases disability, and reduces quality of life. Although immune tolerance induction (ITI) can reduce inhibitors against factor VIII concentrates, the study “Long-term course of…

Transplants of embryonic stem (ES) cells that secrete the human factor VIII (FVIII) may be a promising therapeutic approach for patients with hemophilia A, according to an animal study conducted by researchers at the Nara Medical University School of Medicine in Japan. The study, “Therapeutic approaches for treating hemophilia…

The genetic blood disorder hemophilia B, caused by factor IX (FIX) deficiency, can be effectively controlled with gene replacement therapies, particularly when used for prevention. But because barriers to prophylaxis that include intravenous use, frequent dosing and medical costs are many, new research for better therapies is emerging. Researchers at the University of Wisconsin School of…

Facial and scalp swelling can be indicators of childhood hemophilia, but for children who are misdiagnosed and treated incorrectly, the effects of the disease’s elevated bleeding predisposition can be catastrophic. In the study, “Facial and Scalp Swelling in the Pediatric Population With Hemophilia: A Diagnosis Pitfall,” published in…

Dimension Therapeutics recently revealed positive preclinical results from a novel adeno-associated virus (AAV) that delivers Factor VIII as a therapeutic approach for hemophilia A patients. The results were presented in a poster, titled “Optimized AAV-Mediated Human Factor VIII Gene Therapy in Hemophilia A Mice and Cynomolgus Macaques” at the 19th American Society of…
