Intellia Therapeutics and Regeneron are planning to begin, by mid-year, the first-in-human trial testing a CRISPR/Cas9-based Factor 9 (F9) gene-editing therapy for people with hemophilia B. The announcement of the planned launch of the Phase 1 clinical trial, in an Intellia financial report, follows the recent approval by…

In our quest for security and certainty, it’s only natural to gravitate toward options that offer zero risk. Think about it: When you purchase insurance or opt for a product with a money-back guarantee, you’re essentially seeking assurance against any potential loss. This tendency to avoid risk at all…

In the 1970s and ’80s, treating my von Willebrand disease and hemophilia B often involved a regimen that included fresh frozen plasma, platelets, and cryoprecipitate. Cryoprecipitate, a blood component derived from frozen plasma, contains vital clotting factors such as fibrinogen, factor VIII, von Willebrand factor, and factor…

Almost three years of treatment with SerpinPC was associated with a nearly complete resolution of bleeds and a reduction in the number of affected joints among men with severe hemophilia A or B who participated in a Phase 1/2a clinical trial. The…
