When given as a preventive treatment for nearly six years, Hemlibra (emicizumab) safely and effectively lowered the number of bleeding episodes in patients with severe hemophilia A, according to data from a Phase 1 clinical trial and its long-term extension study. Importantly, reductions in the number of bleeds…

Note: This story was updated Jan. 8, 2021, to clarify that the second set of experiments in mice and non-human primates used a research construct, not the gene therapy. Generation Bio has announced new data showing that its investigational non-viral gene therapy platform can increase levels of the clotting…

Prime Therapeutics and Takeda will work together to establish the value of Advate, relative to its costs and benefits, as a treatment for hemophilia A. According to Prime, work comparing factors like total health care costs and emergency hospital visits allow the company to better evaluate and distinguish…

The U.S. Food and Drug Administration (FDA) has granted fast track designation to marzeptacog alfa activated (MarzAA), a lab-made version of clotting factor VIIa for the subcutaneous (under-the-skin) treatment of episodic bleeds in hemophilia A and B patients with inhibitors. MarzAA, developed by Catalyst Biosciences, will…

Using a combination of genetic and functional approaches, scientists have identified new mutations in parts of the F8 gene that do not code for factor VIII (FVIII) in a small group of French and Canadian patients with hemophilia A. These results were described in the study, “The…

Hemlibra (emicizumab) continues to safely and effectively prevent bleedings in children and adults with hemophilia A, regardless of developing neutralizing inhibitors (antibodies) against synthetic factor VIII (FVIII), according to nearly three years of data from four Phase 3 clinical trials. These and preliminary real-world safety findings from a European…

Prophylactic (preventive) treatment with Adynovate safely and effectively lowers the number of bleedings, including those in target joints, in children and adults with severe hemophilia A, according to data from two Phase 3 clinical trials. Notably, personalized Adynovate treatment targeting higher minimum blood levels of factor VIII (FVIII) —…

Preventive treatment with Hemlibra (emicizumab) improves health-related quality of life (HQRoL) in children with hemophilia A who develop inhibitors, or neutralizing antibodies, against engineered factor VIII (FVIII), an essential blood-clotting protein, a new analysis of a Phase 3 trial shows. Such Hemlibra therapy also reduces the burden on…

At standard U.S. doses, Hemlibra (emicizumab) provides comparable or even superior clinical benefits than prophylactic factor VIII (FVIII) replacement therapy among adults with severe hemophilia A and no inhibitors, according to a report from the Institute for Clinical and Economic Review (ICER). Hemlibra is also cost-saving, due to…

Long-term treatment with Esperoct (turoctocog alfa pegol) prevented bleeding in one-fifth of children with severe hemophilia A over the course of a Phase 3 clinical trial, according to final results from the study. Treatment was effective in both spontaneous and traumatic bleeds, and appeared to be…
