CSL Behring’s expensive hemophilia B gene therapy is to be reimbursed by the U.K. National Health Service, after the company agreed to an outcomes-based payment scheme. The therapy, Hemgenix (etranacogene dezaparvovec), which has a U.K. list price of £2.6 million (US$3.3 million), was approved under a managed access scheme, in which data will be collected over five years to enable both the long-term effectiveness, and any adverse liver toxicity caused by the transgene, to be monitored.

Using his new platform as chair of the U.S. Senate Health, Education, Labor and Pensions Committee, Sen. Bernie Sanders (I-Vt.) is again pushing the Biden administration to reinstate, and strengthen, a “reasonable pricing clause” in all future research agreements involving government agencies, especially those funding drug R&D.

Little more than a month after the U.S. FDA approved the first gene therapy for adults with hemophilia B, Uniqure NV’s Hemgenix, strong phase III data have come from Pfizer Inc. The Pfizer results show fidanacogene elaparvovec, a vector containing an AAV capsid and a high-activity human coagulation factor IX (FIX) gene for treating adult men with moderately severe to severe hemophilia B, hit the primary endpoint in the phase III Benegene-2 study. The one-time therapy is designed to allow those living with hemophilia B to be able to produce FIX instead of receiving regular, ongoing doses of exogenous FIX.

The U.S. FDA gave its go-ahead for Hemgenix (etranacogene dezaparvovec-drlb), Uniqure NV’s one-time gene therapy – the first for the treatment of adults 18 and older living with hemophilia B. Patients have been waiting “maybe beyond two decades” for a new therapy, Uniqure CEO Matthew Kapusta said. Hemgenix emerged from pioneering work by St. Jude Children’s Research Hospital and the University College London.
