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…

A participant in a Phase 3 clinical trial evaluating Roctavian (valoctocogene roxaparvovec), a gene therapy for hemophilia A, has been diagnosed with leukemia. A genetic assessment of the case, conducted by the therapy’s developer, BioMarin Pharmaceutical, suggested the cancer diagnosis was not linked to Roctavian. Details of…

The European Commission has granted conditional marketing authorization to BioMarin’s one-time gene therapy Roctavian (valoctocogene roxaparvovec) as a treatment for adults with severe hemophilia A who have neither inhibitors nor detectable antibodies against adeno-associated virus serotype 5 (AAV5). The decision, which comes a couple of months after a…

A single dose of Freeline Therapeutics’ experimental gene therapy FLT180a increased the levels of factor IX (FIX) — the missing clotting protein in hemophilia B — for up to around 3.5 years in nine out of 10 men with moderate-to-severe disease. That’s according to data from the Phase…

The first three participants in the B-LIEVE trial all have factor IX (FIX) levels within the normal range more than one month after being treated with FLT180a, Freeline’s experimental gene therapy for hemophilia B, according to the company. “The initial data show that FLT180a provides rapid and consistent…

Nearly one-third of people with hemophilia B have antibodies against a subtype of an adeno-associated virus (AAV) — called AAV6 — that is used as an experimental gene therapy carrier, a U.K. study found. Because such antibodies could render the treatment that the carrier holds ineffective, these patients would…

European authorities have recommended conditional marketing authorization for Roctavian (valoctocogene roxaparvovec), BioMarin Pharmaceutical’s one-time gene therapy for adults with severe hemophilia A. This positive decision, from the Committee for Medicinal Products for Human Use (CHMP), makes Roctavian the first gene therapy for hemophilia A to be recommended for European…

ASC Therapeutics has joined forces with Charles River to scale the manufacturing of ASC618, its second-generation virus-based gene therapy for hemophilia A. The agreement expands upon their current collaboration, begun in 2019 that focused on achieving Good Manufacturing Practice (GMP)-virus manufacturing and establishing processes for adeno-associated virus (AAV) production…

Preventive treatment with a low dose of factor replacement therapy in children with hemophilia A led to sufficient levels of the clotting factor in most patients, but the time in which it did so varied, a recent study reported. Researchers noted that while findings support the use of this…

The U.S. Food and Drug Administration (FDA) has granted breakthrough therapy designation to efanesoctocog alfa, an experimental replacement therapy for hemophilia A designed for once-weekly dosing. This designation is given by the FDA to help speed the development and review of treatments for serious or life-threatening conditions. Specifically,…
