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…

Mild to moderate hemophilia B affects the relationships of adult patients, children with the disease and their caregivers in aspects such as telling others about the diagnosis, selecting a partner, and feeling bullied, according to an American study. The research, “Mild-severe hemophilia B impacts relationships of…

Clinical trials of Hemlibra (emicizumab-kxwh) continue to show significant reductions in bleeding episodes in patients with hemophilia A with inhibitors, Genentech recently announced. Data from Hemlibra’s clinical development program were presented at the 59th American Society of Hematology (ASH) Annual Meeting. The results show that in hemophilia A patients with inhibitors…

Interim results of Phase 3 clinical studies investigating two major challenges in hemophilia — the development of inhibitors (antibodies to the drug used to treat bleeding episodes) and the need for repeated venous injection of blood clotting protein Factor VIII (FVIII) — were recently released. The results were presented by…

Combining two gene editing approaches in cells derived from a patient with severe hemophilia A successfully restored the levels and activity of the faulty clotting factor VIII (FVIII) and reduced bleedings in a mouse model of the disease, according to a new study. The research, “ssODN-Mediated…

Although most patients report that discussing their sexual health with their doctors is helpful, hemophilia significantly affects the quality of their sex lives, according to the results of two studies. The research, “Hemophilia and sexual health: results from the HERO and B-HERO-S studies,” was published in…

Preliminary results of a Phase 1/2a trial of the hemophilia A experimental treatment BIVV001 show a significant extension of replacement therapy lifetime in the blood, Bioverativ announced. The ongoing, and still recruiting, open-label, multicenter EXTEN-A study (NCT03205163) is evaluating the safety, tolerability, and pharmacokinetics of a single intravenous injection…

Researchers are creating a free web-based calculator that will help physicians determine the best patient-specific preventive regimens for children with hemophilia, according to a recent study. The tool is based on newly developed methods that identified key features of an effective preventive regimen. This includes giving Factor VIII (FVIII) injections…

Hemophilia patients may now benefit from financial assistance for out-of-pocket expenses, health insurance premiums, and incidental medical costs following the launch of a new program from The Assistance Fund (TAF). Founded in 2009, TAF is an independent nonprofit aimed at helping eligible patients and their families cover costs not…

Researchers report that hemophilia interferes with patients’ sexual activity and is linked to worse health status. The study titled “Sexual Health in Patients with Hemophilia; The Insights from the Patient Reported Outcomes, Burdens and Experiences (PROBE) Study,” appeared in the journal Blood. Previous results from a small…
