Von Willebrand disease (VWD) is an inherited bleeding disorder with an estimated prevalence between 23 and 110 per 1 million people. These numbers vary because the criteria for diagnosis are not always the same. Causes of VWD VWD is caused by mutations in the VWF gene. This gene…
A new collaboration between St. Jude Children’s Research Hospital and the World Federation of Hemophilia (WFH) is aimed at helping blood disorder patients in countries where they may not receive regular treatment. The partnership’s centerpiece will be a program to conduct a gene therapy clinical trial in…
Hemophilia is a blood disorder that is characterized by a shortage of specific clotting factors that help to form blood clots and stop bleeding. The primary treatment for hemophilia is replacement therapy that supplies the clotting factors to hemophilia patients who lack them. Other approved hemophilia treatments include…
Hemophilia B Leyden (HBL) is a sub-type of hemophilia B, a genetic bleeding disorder characterized by a lack of a blood-clotting protein called factor IX. HBL accounts for approximately 3% of all hemophilia B cases. HBL is distinct from other forms of hemophilia because, while it is caused by…
Hemophiliacs in Europe have never had so many reasons to feel hopeful about the future, thanks to significant recent scientific advances. But “vested interests, entrenched systems, and blatant, outright corruption limit access” to even basic healthcare in some Eastern European countries, says Amanda Bok, CEO of the Brussels-based European…
Investigational gene therapy SB-525 is well-tolerated and leads to a dose-dependent increase in factor VIII (FVIII), according to interim results from eight patients with severe hemophilia A enrolled in the Phase 1/2 Alta clinical trial. Data showed that patients who received the highest dose of SB-525 — 3e13 vg/kg dose — reached…
Researchers have identified four distinct subgroups of hemophilia A patients according to their profile of factor VIII-targeting antibodies. This may help predict those at risk for developing inhibitors that halt the efficacy of FVIII replacement therapy. The results were presented in a poster titled “Data Coming out of the…
FLT180a, also known as verbrinacogene setparvovec, is an investigational gene therapy that was investigated as a treatment for people with hemophilia B.
A Phase 3 clinical trial of treatment candidate AMT-061 for severe and moderately severe hemophilia B has treated its first patient. The open-label HOPE-B study (NCT03569891) is testing the safety and effectiveness of AMT-061 in adult men with hemophilia B. Patient recruitment is continuing for an estimated total of 56…
Repetitive movements, fitness level, and prolonged and competitive physical activity are among the factors that raise bleeding risks for people with hemophilia taking part in such activities, a study based on a survey of physical therapists in the U.S. reports. Duration of training and safety equipment were seen as modifiable factors,…
