Hemlibra (emicizumab) was able to prevent excessive bleeding in patients with severe hemophilia A without inhibitors, according to results from a Phase 3 trial. Trial findings were published in the study, “Emicizumab Prophylaxis in Patients Who Have Hemophilia A without Inhibitors,” in The New England Journal of…

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…

Testing levels of thrombin — an enzyme that helps blood clot — in people with acquired hemophilia A could help doctors fine-tune care for these patients when both clot-promoting and blood-thinning medications are used. That’s the conclusion drawn by researchers in the Netherlands, who found that thrombin testing in…

Prophylactic, or preventive, use of Hemlibra (emicizumab) promotes joint health in people with hemophilia A, according to a new analysis of data from a Phase 3 trial. These findings were announced in the oral presentation “Bone and Joint Health Markers in Persons with Hemophilia A (PwHA)…

A major complication in scientists’ efforts to treat hemophilia A by replacing a missing or defective clotting factor is an immune response to the treatment. Researchers have discovered a connection between the body’s production of pro-inflammatory molecules known as cytokines and its immune response to clotting factor VIII therapy. They used…

The incidence of acquired hemophilia A (AHA) was nearly twice as high in Hong Kong than in Caucasian populations previously observed, a study found. Patients in Hong Kong tended to be older and have co-existing medical conditions, with age being a significant predictor of mortality and failure to achieve…

Note: This story was updated July 30, 2024, to clarify patients participating in AFFINE had moderately severe to severe disease, and that a secondary study goal involved the mean treated annualized bleeding rate. Giroctocogene fitelparvovec, an investigational gene therapy for adults with hemophilia A, is generally well…

Prophylactic (preventive) treatment with Hemlibra (emicizumab) safely and effectively reduces bleeding rates in children younger than 12 with hemophilia type A, regardless of development of inhibitors (antibodies) against synthetic factor VIII (FVIII), data from two Phase 3 studies show. Hemlibra is a type of replacement therapy that mimics…

Two years of preventive treatment with Genentech’s Hemlibra (emicizumab) safely and effectively lowered the number of bleeds in people with hemophilia A and clotting factor VIII (FVIII) inhibitors, according to final data from the Phase 3b STASEY trial. Development of antibodies against the therapy (anti-drug antibodies) was…

SARS-CoV-2, the virus that causes COVID-19, might have triggered acquired hemophilia A (AHA) in a 65-year-old man with a clinical history of autoimmune thyroid disease, a U.S. case study reports. This case suggests that COVID-19 infection should be considered when looking for potential causes of AHA. The study, “…
