A gene therapy from uniQure in early testing, called AMT-180, has the the potential to treat all hemophilia A patients, including those with inhibitors, according to the company. Hemophilia A is caused by missing or defective factor VIII (FVIII), a clotting protein. About 30% of patients with severe hemophilia A develop inhibitors, or…

SPK-8016, also known as RG6358, is an experimental gene therapy that was being investigated for hemophilia A patients who had developed neutralizing antibodies (inhibitors) against clotting factor VIII (FVIII).
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…
Hemophilia A patients undergoing total hip or knee replacement/reconstruction surgeries have lesser blood loss and require a lower transfusion amount if treated with Cyklokapron (tranexamic acid), a study reports. They also are likely to experience less joint pain or swelling and better joint function, and have lower levels…
The relapse rate is higher in older patients with acquired hemophilia A (AHA) treated with immunosuppressive therapies, but it doesn’t affect their overall survival compared with those who don’t relapse, a study suggests. The study, “Relapse pattern and long‐term outcomes in subjects with acquired haemophilia A,” was published in…
Dosing has begun in a Phase 2b clinical trial evaluating the safety and efficacy of SerpinPC, Centessa Pharmaceuticals’ investigational therapy for hemophilia. The open-label study, called PRESent-2 (NCT05789524), is part of the company’s registrational program for hemophilia B, which includes multiple clinical trials aiming to…

Anticoagulant Protein TFPI Crucial to Bleeding Severity Profile of Hemophilia Patients, Study Says
A natural anticoagulant protein called tissue factor pathway inhibitor (TFPI) is critical for defining the bleeding severity profiles of people with hemophilia A and B, researchers in France report. This discovery, which was found not to hold for healthy individuals, adds support to TFPI as an important element…

New Gene Therapy Approach Led to Sustained Benefits in Mouse Model of Hemophilia A, Study Reports
A gene therapy approach using a so-called antibody-drug conjugate (ADC) conditioning regimen led to safe and sustained production of factor VIII (FVIII) in platelets, and prevented joint bleeding in a mouse model of hemophilia A, according to new research. The study, “Nongenotoxic antibody-drug conjugate conditioning…
A new study from Finland demonstrated that neutralizing antibodies (inhibitors) can develop in people with untreated hemophilia, and that early intensive prevention might prevent bleeding and inhibitor development. The research report, titled “Inhibitor development in previously untreated patients with severe haemophilia A: a nationwide multicentre study in Finland,” was published in…
Pfizer said the U.S. Food and Drug Administration (FDA) will review the company’s request to expand approval of its preventive treatment Hympavzi (marstacimab) to cover all people with hemophilia A or B ages 6 and older. Hympavzi is FDA-approved to treat hemophilia A and B in patients ages…
