Andrew Davidoff, M.D., Chair, Surgery, St. Jude Children's Research Hospital, added, "We are pleased that our research with UCL on gene therapy for hemophilia has led to the development of a potential therapeutic tool for treating this devastating disease. This licensing agreement underscores St. Jude's commitment to rapidly translating our research into effective clinical interventions."

About Hemophilia A

The current market for hemophilia A products is about $6.0 billion worldwide. There are approximately 90,000 patients in territories where BioMarin has commercial operations and an annual incidence of about 400 new patients in the U.S. The standard of care for the 60 percent of hemophilia A patients who are severe is a prophylactic regimen of IV infusions three times per week.  Even with the likely prospect of less frequently dosed products coming to the market, feedback from thought leaders indicates that significant unmet need will remain as factor replacement therapy will inevitably leave patients vulnerable to bleeding events. Many patients on factor replacement therapy still have bleeding events and experience debilitating damage to joints as a result of chronically low factor levels.
