High levels of antibodies against clotting factor VIII (FVIII) were associated with a slower response to immunosuppressive treatments in a small group of people with acquired hemophilia A in new study in China. Of 34 patients, 29 achieved a complete response to their first-line immunosuppressive therapy. Still, a lower…

Most people with severe hemophilia A who were given once-weekly treatment with efanesoctocog alfa in the Phase 3 XTEND-1 trial were bleed-free over a year on treatment. The therapy also improved joint and overall physical health and eased pain intensity in the participants compared with previous treatments. Results…

An investigational factor VIIa (FVIIa) therapy called GEN-0828 may be able to minimize blood loss and accelerate blood clotting at lower doses than NovoSeven, an approved medication used to control bleeding in hemophilia patients, according to a study in a mouse model of hemophilia B. Still, both treatments…

The World Federation of Hemophilia (WFH) has launched a registry to monitor long-term outcomes of safety and effectiveness for people with hemophilia who receive gene therapy treatment. The aim of the WFH Gene Therapy Registry (GTR) is to collect data for all patients who have gene therapy, whether through…

Treatment with the experimental gene therapy fidanacogene elaparvovec led to significant reductions in bleeding rates for men with moderately severe to severe hemophilia B who participated in a Phase 3 clinical trial. That’s according to top-line data from the study BENEGENE-2 (NCT03861273), recently announced by the therapy’s developer,…

Three years after receiving the one-time gene therapy Roctavian (valoctocogene roxaparvovec) at trial, the majority of men with severe hemophilia A in the Phase 3 GENEr8-1 study were off standard replacement therapies and did not experience any bleeds requiring treatment. That’s according to new data announced in a…

The U.S. Food and Drug Administration (FDA) has cleared CRYOcheck Chromogenic Factor IX assay, a test intended to be used by clinical labs to detect a deficiency in factor IX (FIX), the cause of hemophilia B. The chromogenic, or color-based, test developed by Precision BioLogic is reported…

One-time treatment with the investigational gene therapy SPK-8011 led to sustained low bleed rates for people with hemophilia A in a Phase 1/2 clinical trial. That’s according to data of up to 5 years of follow-up presented by the therapy’s developer, Spark Therapeutics, at the annual meeting of…

Preventive treatment with Hemlibra (emicizumab) appears to be safe and helps keep bleeding under control in babies who have severe hemophilia A. The number of bleeds was “zeroed out” in nearly half of the babies, and most had zero bleeds requiring treatment. That’s according to interim results from…

A committee of the European Medicines Agency (EMA) has issued a positive opinion recommending the one-time gene therapy etranacogene dezaparvovec be granted conditional marketing authorization to treat appropriate adults with hemophilia B. The recommendation from the EMA’s Committee for Medicinal Products for Human Use (CHMP) will now be…
