Adults and adolescents with hemophilia A or hemophilia B without inhibitors experienced significantly fewer bleeding episodes when using concizumab as a prophylactic (preventive) treatment compared with those who weren’t on any prophylaxis. That’s according to data from explorer8 (NCT04082429), an ongoing Phase 3 clinical study in which…

Over seven years of follow-up, a single dose of Roctavian (valoctocogene roxaparvovec-rvox) sustainably reduced the yearly bleeding rate in adults with severe hemophilia A by up to 96%. That’s according to an update on a Phase 1/2 clinical trial (NCT02576795), launched in the U.K. in 2015, that’s…
Scientists in Taiwan have created a new point-of-care device to diagnose hemophilia type A and determine a person’s blood type using just a small sample of blood. The device “is especially suitable for usage in emergency or natural disasters to provide quantitative testing in rescue and relief operations,” the…
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…
Preventive treatment with a low dose of factor replacement therapy in children with hemophilia A led to sufficient levels of the clotting factor in most patients, but the time in which it did so varied, a recent study reported. Researchers noted that while findings support the use of this…
Two new mutations affecting the production of functional clotting factor VIII were identified in a group of Vietnamese patients with hemophilia A, researchers report. Their findings were described in a letter to the editor, “Mutation characteristic of 103 haemophilia A patients in Vietnam: Identification of novel mutations,”…
In people with hemophilia A, certain immune markers in the blood may help predict patient responses to immune tolerance induction (ITI) — a treatment regimen used for individuals who develop inhibitors after factor replacement therapy — according to a new study by researchers in Brazil. Inhibitors, neutralizing antibodies…
A therapy designed to promote the growth of regulatory T-cells (Tregs) in the body prevented inhibitor development in a mouse model of hemophilia A that was treated with factor replacement therapy, a study showed. Inhibitors, a type of neutralizing antibody some patients develop that can make replacement therapies…
Julian MacDonald opens up about life with severe hemophilia A, from early diagnosis to the financial and insurance challenges he faced in adulthood. He shares how leaning on pharmacists, care teams, and the broader hemophilia community became essential to understanding he didn’t have…
The U.S. Food and Drug Administration (FDA) recently granted orphan drug status to SHP654 (BAX 888), an investigational factor VIII (FVIII) gene therapy candidate being developed by Shire for the treatment of hemophilia A. Gene therapy allows the delivery of a functional copy of the defective gene.
