The first documented case of a previously untreated hemophilia B patient developing inhibitors against the extended half-life therapy Alprolix was described in a report from Canada. The report also shows how combining routine administration of Alprolix with medications that suppress the immune system can be used to stop…

Poseida Therapeutics and Takeda are working together to develop non-viral gene therapies for hemophilia and other genetic diseases. “Together with Takeda, we look forward to developing potential cures for a number of genetic diseases with high unmet need,” Eric Ostertag, MD, PhD, Poseida’s CEO, said in a press…

A newly designed platform based on the principle of “reverse vaccination” could be used to prevent the development of an immune response that blocks the effectiveness of treatments for hemophilia and other disorders. “For nearly a third of patients with hemophilia A … their own immune system is…

Most people with hemophilia A on preventive treatment with Hemlibra (emicizumab) will experience spontaneous or traumatic bleeds at some point, according to a study using real-world data from Israel. Results also indicated the risk of spontaneous bleeds while on Hemlibra is higher for older individuals. “Our findings indicate that…

Preventive treatment with Hemlibra (emicizumab) safely and effectively reduced bleeding rates in children with hemophilia A who were treated at a center in Texas, according to a new report. “We demonstrate a successful experience with emicizumab prophylaxis and safe [surgical] approach with a focus on minimizing postoperative bleeding,”…

Two pharmaceutical companies, LeaderMed Health Group and OPKO Health, are teaming up to develop, manufacture, and commercialize two experimental medications in China and other locations in Asia. One of the investigational medicines, Factor VIIa-CTP, is being developed as a potential treatment for hemophilia. “Through this joint venture, we…

The U.S. Food and Drug Administration (FDA) has restored its approval of BeneFIX as a routine prophylactic, or preventive, treatment for bleeds in children and adolescents under 16 with hemophilia B. Marketed by Pfizer, BeneFIX is a lab-made version of factor IX (FIX), the blood clotting protein that…

Preventive treatment with marzeptacog alfa activated (MarzAA) can reduce bleed frequency substantially in men with hemophilia A or B who developed inhibitors to conventional replacement therapies, according to data from a Phase 2 clinical trial. The findings were reported in the study, “Subcutaneous engineered factor…

Treatment with the investigational gene therapy Roctavian (valoctocogene roxaparvovec) can reduce bleeding frequency and the use of replacement therapies, while maintaining or improving the quality of life of people with severe hemophilia A for up to five years, updated Phase 1/2 trial data show.  “These…

Effectiveness in controlling bleeds and the potential for less frequent use of a treatment are two priorities people with hemophilia place on a potential gene therapy, and both ranked slightly higher than safety, a survey study of patients in the U.S. reports. The study, “Patient preferences and…
