Low-dose immune tolerance induction (ITI) — a type of treatment that can be used to eliminate inhibitors that limit the effectiveness of replacement therapies — achieved partial success in 80% of children with severe hemophilia A and high inhibitor levels, according to a recent study. The study, “…

2seventy Bio has expanded its collaboration with Novo Nordisk to develop a gene-editing approach to treat hemophilia A. The new venture adds to an ongoing partnership between 2seventy’s parent company, Bluebird Bio, and Novo Nordisk, which focused on finding new gene therapy candidates. Under this…

The first man with hemophilia B has been dosed in a clinical trial in China to evaluate Belief BioMed’s investigational one-time gene therapy BBM-H901. According to the company, BBM-H901 is the first investigational gene therapy given intravenously, or directly into a vein, for hemophilia B or any genetic disease…

When given monthly to people with hemophilia A or B with inhibitors, fitusiran significantly reduced bleeding, and for some, fully eliminated them, according to data from the Phase 3 ATLAS-INH study.

The U.S. Food and Drug Administration (FDA) has placed a clinical hold on the Phase 3 trial evaluating SB-525 (giroctocogene fitelparvovec), an investigational gene therapy for hemophilia A. This pause in study recruitment and dosing was taken to give the agency time to review changes to the AFFINE…

Implanting bioscaffolds — 3D biological scaffolds made up of collagen and other molecules — carrying transformed liver cells into rats successfully triggered the production of factor VIII (FVIII), the clotting protein missing in people with hemophilia A. According to researchers, these bioscaffolds may be a therapeutic alternative to FVIII…

Differences in sensory detection and pain thresholds were found in hemophilia patients taking prophylactics, compared to healthy individuals, and these differences did not change over the course of a one-year follow-up study. These findings indicate that “under prophylactic treatment, the existing difference in the pain profile between [people with…

SerpinPC, an experimental hemophilia therapy, at high dose safely reduced overall bleed rates by up to 88% and spontaneous joint bleeds by up to 94% in adults with severe hemophilia A and B, who were not using preventive treatment, according to top-line results from a Phase 2a…

Therapeutic plasma exchange (TPE) was found to reduce bleeding and ease disease symptoms in six people with acquired hemophilia A (AHA), a case series reported. These findings support TPE — in which the liquid part of blood is replaced with substitute plasma — as an alternative treatment option in…

The U.S. Food and Drug Administration (FDA) has placed a clinical hold on Sigilon Therapeutics’ Phase 1/2 study evaluating the investigational therapy SIG-001 in adults with severe or moderately severe hemophilia A. The move comes after a serious adverse event (SAE) occurred involving one of the three participants…
