With my oldest son, who is now 21, I never worried about limitations. He played soccer for a season, and that was the extent of his athletic pursuits. He just did not like sports and to this day, he does not understand the basics of a football game,…

Endothelial cells — those that line the inside of blood vessels — derived from stem cells of people with hemophilia A and modified to produce functional factor VIII were able to ease blood loss in a mouse model of the disease, a study reported. These findings support the potential of induced…

European authorities have recommended conditional marketing authorization for Roctavian (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s one-time gene therapy for adults with severe hemophilia A. This positive decision, from the Committee for Medicinal Products for Human Use (CHMP), makes Roctavian the first gene therapy for hemophilia A to be recommended for European…

A first patient has been dosed in a Phase 1/2a clinical trial that’s assessing the safety and preliminary efficacy of ASC618, a second-generation gene therapy for hemophilia A. The Phase1/2a study (NCT04676048), which has been in the works since 2021, aims to enroll about 12 men with severe…

Gene therapy delivering the blood clotting factor VIII (FVIII) — whose lack causes hemophilia A — into the joints did better at protecting against hemophilic arthropathy (joint damage) than did administration into the bloodstream, a study in mice suggests. Its findings support the potential use of FVIII injected directly into…

The first patient in a Phase 1/2 clinical trial (“the Alta trial”) designed to assess safety and tolerability of SB-525 gene therapy has received treatment. Sangamo Therapeutics, in a collaboration with Pfizer, is developing  the SB-525 gene therapy to correct the Factor VIII (FVIII) defect in hemophilia A…

The U.S. Food and Drug Administration (FDA) has accepted — under priority review — a marketing application for EtranaDez (etranacogene dezaparvovec), an investigational gene therapy for adults with hemophilia B. The FDA grants priority review to investigational therapies designed to treat serious medical conditions. If approved, the treatment…

Re-administering a viral vector-based gene therapy for hemophilia A was shown to be safe and to achieve long-term improvement in a dog model of the disease — even after neutralizing antibodies were evident following the initial treatment. The study, “An observational study from long-term AAV re-administration in…

Pfizer is preparing to launch its hemophilia B gene therapy Beqvez (fidanacogene elaparvovec-dzkt) after securing a U.S. approval for the treatment last month. Beqvez is the second gene therapy to be approved for adults with moderate to severe hemophilia B in the U.S., following the clearance of…

CAR T-cell therapy, a type of treatment that weaponizes the body’s immune system and was originally developed to treat cancer, for the first time successfully treated a patient with acquired hemophilia A (AHA), a study reported. The study, “Anti-CD19 CAR-T cell therapy for acquired hemophilia A,”…
