The first participant has been dosed in a Phase 3 clinical trial testing marzeptacog alfa activated (MarzAA), an experimental under-the-skin therapy for hemophilia A and B patients with inhibitors. The study, called Crimson-1 (NCT04489537) and sponsored by the therapy’s developer, Catalyst Biosciences, is currently recruiting patients at sites…

Bayer’s Jivi safely and effectively prevents bleeds during and after minor surgery in children, adolescents, and adults with severe hemophilia A, according to interim data from the Phase 2/3 PROTECT VIII and the Phase 3 PROTECT VIII Kids clinical trials. Most of the included patients were on…

Hemophilia A patients with factor VIII (FVIII) inhibitors show deficiencies in regulatory B- and T-cells — immune cells that typically dampen immune and inflammatory responses — but their levels can be restored with successful immune tolerance induction (ITI), a study shows. These findings shed light on how ITI — given…

Healthcare costs can be 25 times higher for hemophilia B patients than for individuals who do not have a bleeding disorder, according to a recent study. These findings reflect both direct costs of hemophilia treatment and a greater need for other healthcare resources, researchers noted. The study, “…

Scientists found the immune signaling protein BAFF can promote the formation of neutralizing antibodies, or inhibitors, against blood clotting factor VIII (FVIII), which can lower the effectiveness of FVIII replacement therapies used to treat people with hemophilia A.  They also discovered that hemophilia A…

A first patient has been dosed in XTEND-Kids, a Phase 3 clinical trial evaluating the safety and efficacy of the investigational replacement therapy efanesoctocog alfa in boys with severe hemophilia A. Hemophilia A is caused by the lack of a functional blood clotting protein called factor VIII…

Long-term treatment with Jivi safely and effectively reduced the number of bleeding episodes in adolescents and adults with severe hemophilia A, according to up to seven years of data from the Phase 2/3 PROTECT VIII trial and its extension study. The new data confirmed the previous findings from…

Continuous into-the-vein (intravenous) infusions of Advate immediately before and after major orthopedic surgery is as safe and effective as standard, short, bolus infusions at preventing bleeds in men with moderate-to-severe hemophilia A. That finding from a Phase 3/4 clinical trial — the first controlled trial to compare the two types…

Jivi was safe and effective at preventing and treating bleeds for more than five years in boys under age 12 with severe hemophilia A, according to long-term data from a Phase 3 trial’s extension study. Data analysis also showed that most of…

For people with hemophilia B, switching to Rixubis (nonacog gamma) as a factor IX (FIX) replacement therapy was not associated with increased bleeding rates, dose changes, adverse blood clotting events, or the development of inhibitors among patients with moderate to severe forms of the disease,…
