Pfizer said Thursday that its experimental gene therapy for hemophilia B significantly reduced the number of bleeds patients experienced over a year.
Data from the 45-patient trial could set the stage for a second gene therapy to be approved for patients with the rare and serious bleeding disorder in as many years. In November, UniQure won approval for Hemgenix, the first hemophilia B gene therapy.
“The results from this long-awaited study are great news for hemophilia B patients that soon may have access to a second durable treatment option,” Luk Vandenberghe, a gene therapy expert at Harvard, said in a text message, after reviewing the results.
