From the moment David was born, his family was on the lookout for signs of hemophilia. In 1975, when David was just three months old, he rolled over a plastic rattle in his crib and woke up the next morning covered in bruises. Shortly after, David was diagnosed with severe hemophilia A and soon began his treatment journey.

Despite his diagnosis, David was determined to have a typical, carefree childhood without concerns about physical activity. He quickly discovered his increased risk of injury when simple activities like skipping stairs resulted in painful ankle bleeds and hospital visits.1-2 By age nine, David was being treated with plasma derived factor concentrate, but the frequency of his bleeds eventually resulted in hemophilic arthropathy, and he began using a cane at age 14.

 “That was a constant reminder of my limitations and fragility,” David said. “I had to grow up fast at a very early age.”

From childhood to adulthood, David’s hemophilia treatment significantly evolved, including switching from on-demand treatment to prophylaxis with recombinant factor VIII products, which greatly reduced his bleeds.3 David was able to revisit his childhood passion of singing by pursuing a career as an opera performer, but the physical demands of his job required infusions multiple times per week, or as often as daily when engaging in high-risk activities.1

“When I was younger, I imagined that every physically rigorous profession was off limits to me. But I think it was possible for me to pursue opera precisely because of the evolution of care between the time I was born and now,” David said.

That’s why David asked his doctor about switching to ALTUVIIIO® [antihemophilic factor (recombinant), Fc-VWF-XTEN fusion protein-ehtl], the first factor VIII treatment for adults and children with hemophilia A to offer once-weekly dosing.3-4 ALTUVIIIO is proven to maintain factor activity levels in the normal to near-normal range (over 40%) for most of the week in adults.4 David’s doctor shared that the most common side effects when taking ALTUVIIIO include headache, joint pain, and back pain, and explained that it’s possible to develop inhibitors while taking this treatment.4

Since starting ALTUVIIIO in 2023, David’s ability to schedule activities has improved and he can begin to enjoy more of the things he loves without the burden of multiple infusions each week.1,4 “ALTUVIIIO is a first-in-class medication that offers me the possibility of establishing a consistent weekly routine,” he said. David worked with Sanofi Patient Support Services to access ALTUVIIIO and secure financial assistance.

Looking ahead, David hopes people will embrace the evolving treatment landscape and take control of their care. “Finding a treatment plan that is the right fit for you and your lifestyle is worth pursuing with your doctor,” he said.
