"Today’s approval of HEMLIBRA represents an important advancement for people with hemophilia A with inhibitors, who have struggled to manage their bleeding disorder and haven’t had a new medicine in almost 20 years. We believe HEMLIBRA will improve protection against bleeds and reduce the treatment administration burden for people with hemophilia A with inhibitors, and we are committed to helping them access this medicine.”
“Before HEMLIBRA, my 7-year-old son needed intravenous infusions that could take up to two hours at least three times a week, so our lives revolved around his treatment. With HEMLIBRA, he now has an injection once a week that he has proudly learned to administer himself to help prevent bleeds. Not only has he had fewer bleeds compared to his prior treatment, he has more time to be a kid and we have more quality time as a family because of the new treatment schedule.”
