Up to 14 months after a one-time infusion of SB-525, an investigational gene therapy, durable increases in the activity of clotting factor VIII (FVIII) are continuing in all five severe hemophilia A patients treated at the highest dose in the Alta Phase 1/2 trial. None of these…

A new type of gene therapy that uses RNA instead of DNA led to rapid and prolonged production of therapeutic levels of factor VIII (FVIII) in a mouse model of hemophilia A, a study reported. The study, “Treatment of…

Three hemophilia B patients said they were able to lead a relatively normal life, including being more active and participating in sports, about three years after receiving the investigational gene therapy AMT-060 in a clinical trial. Their experiences were reported in the study, “The Patient…

A single dose of the experimental gene therapy AMT-180 continues to be well-tolerated and to enhance blood clotting activity independent of factor VIII levels in mouse and primate models of hemophilia A, a study shows. Titled, “Human Dose Prediction of a Novel Factor IX Variant Gene Therapy…

Switching from on-demand to preventive treatment — or prophylaxis — significantly reduces bleeding in adults with hemophilia A, including the elderly, a real-life study shows. The study, “Long‐term analysis of the benefit of prophylaxis for adult patients with severe or moderate haemophilia A,”…

Novo Nordisk reports that its treatments for hemophilia and other disorders remain available, and it is taking measures to support patients during the current COVID-19 pandemic. The company has large stock of medicines and expects to be able to meet pharmacy requests in the U.S. during the…

A Phase 3 clinical trial investigating gene therapy candidate AMT-061 (etranacogene dezaparvovec) has reached its target of dosing 50 participants with moderate or severe hemophilia B. In fact, according to AMT-061 developer uniQure, 54 patients have been given the one-time dose of AMT-061 in the HOPE-B…

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…

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…

Cells derived from hemophilia A patients — genetically reprogrammed to produce a functional clotting factor VIII (FVIII) that’s missing or not working in people with the blood disease — were successfully grafted into hemophiliac mice, restoring blood levels of FVIII and significantly improving…
