One-month treatment with Hemlibra (emicizumab) and an immunosuppressive medication were effective for patients with acquired hemophilia at rapidly controlling bleeding and reducing the use of other therapies, a single-center study shows. The researchers also noted that using less toxic immunosuppressive agents such as rituximab was effective at blocking…

The National Institutes of Health (NIH) is supporting a university’s research into the risk factors and underlying mechanisms involved in the development of neutralizing antibodies, or inhibitors, against replacement therapies in people with hemophilia A. The $6.6 million, three-year grant from the NIH’s National Heart, Lung, and Blood Institute…

The U.S. Food and Drug Administration (FDA) has accepted a resubmitted biologics license application (BLA) from BioMarin Pharmaceutical requesting approval of the gene therapy Roctavian (valoctocogene roxaparvovec) to treat adults with severe hemophilia A. The FDA is now expected to decide by the end of March 2023 on whether…

The U.S. Food and Drug Administration (FDA) has cleared the biotechnology company TeraImmune to launch a Phase 1/2a clinical trial testing TI-168, its regulatory T-cell therapy designed to eliminate inhibitors in people with hemophilia A. The upcoming trial is expected to enroll up to 18 people with congenital (genetic)…

BioMarin Pharmaceutical has resubmitted an application to the U.S. Food and Drug Administration (FDA) seeking approval of Roctavian (valoctocogene roxaparvovec), potentially the first gene therapy for adults with severe hemophilia A. The FDA delayed the company’s initial approval request in 2019, with the agency requiring two more…

COVID-19 vaccines, because they work to stimulate the immune system, may be an emerging cause of autoimmune conditions like acquired hemophilia A, according to a case report. “This report aims to highlight the risk of … [acquired hemophilia A] following an immune stimulus, thus improving our knowledge regarding possible…

A significant proportion of bleeds in people with hemophilia A are left untreated, according to an analysis of data from an observational study. Because only treated bleeds are typically reported in clinical trials, these findings suggested the full disease burden is not adequately captured in many studies. As such,…

Men with moderate-to-severe hemophilia A are again being enrolled in the Phase 3 AFFINE trial, which is testing the safety and effectiveness of SB-525 (giroctocogene fitelparvovec), an experimental gene therapy being developed by Pfizer and Sangamo Therapeutics. Pfizer, the study’s sponsor, had placed a voluntary pause…

Treatment with marstacimab (PF-06741086), an experimental antibody-based therapy developed by Pfizer, reduced the number of bleeds in patients with severe hemophilia who took part in a Phase 1b/2 clinical study. This held true regardless of whether patients had hemophilia A or hemophilia B, or had inhibitors…

If approved for hemophilia A, the one-time gene therapy Roctavian (valoctocogene roxaparvovec) would provide substantial cost savings per patient compared with other preventive treatments, specifically Hemlibra. That’s according to a draft evidence report issued by pricing watchdog the Institute for Clinical and Economic Review (ICER). An independent non-profit…
