Scientists in Taiwan have created a new point-of-care device to diagnose hemophilia type A and determine a person’s blood type using just a small sample of blood. The device “is especially suitable for usage in emergency or natural disasters to provide quantitative testing in rescue and relief operations,” the…

Healthcare costs are comparable for male patients with hemophilia A who are treated with either Adynovate (rurioctocog alfa pegol) or Eloctate (efmoroctocog alfa), according to a real-world study in the U.S. “Results from this analysis may be used to inform product coverage and treatment decisions valuable for both…

Bleeding rates and the use of replacement therapies among men with severe or moderately severe hemophilia B remain low at least three years after a single dose of the approved gene therapy Hemgenix (etranacogene dezaparvovec). That’s according to updated data from the Phase 3 HOPE-B clinical trial…

The parents of most children with severe hemophilia A who took part in the XTEND-Kids clinical trial of Altuviiio (efanesoctocog alfa) reported in exit interviews that the once-weekly treatment led to notable improvements in mood for their sons, with some reporting a greater ability for their boys to…

The once-weekly injection therapy marstacimab is being considered for approval in both the U.S. and Europe for people with hemophilia A and hemophilia B who don’t have inhibitors. The U.S. Food and Drug Administration (FDA) is expected to decide on it in late 2024, while a decision from the European…

A first patient has been dosed in a Phase 1/2a clinical trial that’s assessing the safety and preliminary efficacy of ASC618, a second-generation gene therapy for hemophilia A. The Phase1/2a study (NCT04676048), which has been in the works since 2021, aims to enroll about 12 men with severe…

AAV5 DetectCDx, a companion diagnostic test used to determine patient eligibility for the hemophilia A gene therapy Roctavian (valoctocogene roxaparvovec-rvox), has been cleared for use under more stringent European Union rules coming into effect in a few years. Specifically, the test gained the Conformité Européenne (CE) mark under…

The first participant has been dosed in a Phase 2b clinical trial that’s assessing the safety and efficacy of SerpinPC in people with hemophilia B who have inhibitors, according to an announcement from its developer, Centessa Pharmaceuticals. “We are excited to be further evaluating the potential of…

Treatment with platelets stripped of their natural sugar molecule coating helped to prevent inhibitors, or neutralizing antibodies, from forming against clotting factor VIII (FVIII) replacement therapy in a mouse model of hemophilia A, a study reported. Platelets promote blood clotting, and they are generally thought to boost inflammation…

Altuviiio (efanesoctocog alfa) has been approved in Japan and Taiwan as a treatment to prevent and control bleeding in people with hemophilia A. The Japanese Ministry of Health, Labor, and Welfare (MHLW) granted Altuviiio marketing authorization on Sept. 25, according to Sanofi, the company that markets…
