BioMarin sees progress on gene therapy for hemophilia A

Biotechnology specialist BioMarin reported positive results from two studies of its gene therapy treatment for hemophilia A, but shares slipped 5.1%. The company announced that results from its phase 3 study met pre-specified criteria for regulatory review in the U.S. and Europe and provided an update after three years of following patients from an earlier phase 1/2 study.

The treatment, valoctocogene roxaparvovec ("valrox"), transfers to the patient the gene needed to produce clotting factor VIII, which is missing in patients with hemophilia A. In the phase 3 study, eight of 16 patients met the target level of factor VIII, and across all 16 patients, the estimated mean annual bleed rate fell 85% compared with the current standard of care. The phase 1/2 study showed factor VIII levels declined in year three, but appear to be reaching a plateau, leading the company to believe that the effects of the treatment should last at least eight years.

BioMarin intends to review the results with regulatory agencies in preparation for submittal and expects the approval process to support a launch by the end of 2020.
