As a person with von Willebrand disease (VWD) and hemophilia, bruises have been a near-constant presence in my life. VWD and hemophilia are bleeding disorders that affect the body’s ability to form blood clots and stop bleeding. Both can cause spontaneous and excessive bleeding, including bruising, heavy…

When my youngest son, Caeleb, now 17, was 11 months old, he had a bleeding episode that shook us to our core. We’d recently moved to New Mexico from Houston and didn’t yet know our new medical team. Because my wife, Cazandra, had promised to play oboe at…

SerpinPC, a potential treatment for all types of hemophilia, from the drug development pipeline at Centessa Therapeutics, was found to be safe and to reduce patients’ bleeding episodes for up to 1.5 years. In fact, the therapy candidate has the potential to nearly “zero out” the number of…

Despite the increasing use of preventive factor VIII (FVIII) replacement therapy, people living with hemophilia A in Japan still experience a significant disease burden, according to a recent study. Using information from health records databases, researchers found that while patients have used increasing doses and spent more on medical…

Centessa Pharmaceuticals is set to open PRESent-5, an observational feeder study of hemophilia patients who could then move in pivotal clinical trials of SerpinPC — an investigational therapy for hemophilia A and B patients, regardless of disease severity or inhibitor status — that it plans to launch…

Health Canada has expanded its approval of Rebinyn (nonacog beta pegol) as a routine preventive treatment for bleeding episodes in hemophilia B to patients under age 18. The therapy, developed and marketed by Novo Nordisk, is now available to all hemophilia B patients as a preventive (prophylactic)…

The National Institutes of Health (NIH) is supporting a university’s research into the risk factors and underlying mechanisms involved in the development of neutralizing antibodies, or inhibitors, against replacement therapies in people with hemophilia A. The $6.6 million, three-year grant from the NIH’s National Heart, Lung, and Blood Institute…

BioMarin Pharmaceutical has resubmitted an application to the U.S. Food and Drug Administration (FDA) seeking approval of Roctavian (valoctocogene roxaparvovec), potentially the first gene therapy for adults with severe hemophilia A. The FDA delayed the company’s initial approval request in 2019, with the agency requiring two more…

A significant proportion of bleeds in people with hemophilia A are left untreated, according to an analysis of data from an observational study. Because only treated bleeds are typically reported in clinical trials, these findings suggested the full disease burden is not adequately captured in many studies. As such,…
