A single dose of the gene therapy Roctavian (valoctocogene roxaparvovec-rvox) continues to prevent bleeds and the need for preventive treatment (prophylaxis) for up to five years in most treated men with severe hemophilia A, according to final Phase 3 trial results. Activity of factor VIII (FVIII), the clotting…

People whose hemophilia A is mild or moderate can show marked alterations to their joints on MRI scans, particularly in the ankles, despite having few joint bleeds, a study reported. These findings highlight the need for closer monitoring of joint health and a likely need for preventive treatment approaches in patients…

Weekly use of the experimental, long-acting therapy efanesoctocog alfa safely and effectively prevents bleeds in adolescents and adults with severe hemophilia A, according to top-line, one-year data from the Phase 3 XTEND-1 trial. The therapy — being jointly developed by Sanofi and Sobi — was also superior to approved preventive therapies…

Two treatment options for hemophilia A are now available to patients in Canada: Esperoct (turoctocog alfa pegol) and Zonovate (turoctocog alfa), marketed by Novo Nordisk. The therapies have been accessible through Canadian Blood Services since April 1. “As part of our continued commitment to provide support to Canadians…

Sevenfact (eptacog beta) was deemed safe and effective at stopping bleeds in patients with hemophilia A or B with inhibitors, according to real-world data from a case series study in the U.S. The treatment was also more affordable than other similar therapies and effective even in patients who’d failed…

Treatment with abatacept, a medication approved for rheumatoid arthritis, prevented the formation of inhibitors against hemophilia A replacement therapies in a rat model, a study demonstrates. These findings support the use of abatacept to prevent immune responses against human proteins in a preclinical setting, the researchers noted. The study,…

A single dose of the investigational gene therapy SB-525 (giroctocogene fitelparvovec) continues to prevent bleeds and the need for prophylaxis, or preventive treatment, for at least two years in men with severe hemophilia A. These are the latest results from the five men given the highest dose of the…

Immune checkpoint inhibitors (ICIs) used for cancer treatment may be associated with an increased likelihood of developing acquired hemophilia A, according to an analysis of an adverse events database. Although the small number of reports do not confirm that these therapies are causing the bleeding disorder, early identification and…

ASC Therapeutics has gotten exclusive rights to Expression Therapeutics‘ technology to develop liver-targeting hemophilia A gene therapies. “We have a common mission with Expression Therapeutics — to develop novel therapies that will dramatically improve the lives of persons with hemophilia around the world. Hemophilia A is a…

A small percentage of young people with hemophilia A who are on preventive treatment with Hemlibra (emicizumab) experience severe muscle bleeds that require prolonged factor replacement therapy. These are the findings of a real-world, multicenter study in the U.S. which also show that most of these severe muscle…
