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 partnership between ARUP Laboratories and Medicover will improve access to AAV5 DetectCDx, the former’s companion diagnostic test to assess hemophilia A patients’ eligibility to Roctavian (valoctocogene roxaparvovec-rvox) in the European Union (EU). The partnership, which allows testing to be done at one of Medicover’s…

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…

Eligible patients with severe hemophilia A in Germany should now have improved access to Roctavian (valoctocogene roxaparvovec-rvox) — a gene therapy intended to reduce bleed risk in certain adults with the bleeding disorder — given a new agreement between its developer BioMarin Pharmaceutical and the German National Association…

The U.S. Food and Drug Administration (FDA) has given orphan drug and rare pediatric disease designations to Sernova’s experimental and cell-based hemophilia A treatment program using the Cell Pouch System, the company’s novel medical device. Orphan drug status is awarded to therapies aiming to treat…

Adding an antibody targeting the anticoagulant protein S to factor IX (FIX) replacement therapy accelerated blood clotting in samples from children with hemophilia B, including those with severe disease, a study showed. Greater production of the blood clotting protein thrombin also was seen in these samples, while blocking…

GS1191, a gene therapy in the pipeline of Gritgen Therapeutics, increased factor VIII (FVIII) activity in the blood of people with hemophilia A taking part in a small clinical trial in China, resulting in fewer bleeding episodes. The fully enrolled investigator-initiated trial (ChiCTR2300073179) is testing the safety and…

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…
