Meet Tara and Jack
“Jack was a lively toddler. He bruised easily from a typical day of playing outside. My oldest daughter, Katie, was the same way. Yet we didn’t think much of it. Katie developed tonsillitis, and when they did her blood work, they found out she had hemophilia. That threw a lot of things into perspective. All those bumps and bruises weren’t an everyday part of rural living; they were symptoms. We tested the rest of the family. My middle daughter does not have hemophilia, but Jack also tested positive for mild hemophilia A. This was in February 2013, when he was 2 years old.
Jack’s first treatment was an on-demand treatment that wasn’t effective for us, so we switched to a recombinant factor, but infusing Jack at that young age was impossible. He fought it so hard that we’d miss treatments. That was a very hard time for all of us, but we knew Jack was a very active boy and wanted to play sports. As he got older, Jack understood that prophy treatment was best for accommodating that choice, and infusions became more manageable.
Jack had been on a factor mimetic subcutaneous treatment, which is administered under the skin, since he was 10, and he also had another factor treatment for breakthrough bleeds. That became a lot for us to track. We were ready for another option, and Jack was becoming increasingly open to infusions.
Last year, while talking to his hematologist about other prophy treatment options, she told us about ALTUVIIIO. She shared that ALTUVIIIO is the only once-weekly prophylaxis Factor VIII replacement therapy. ALTUVIIIO was also shown to have higher-for-longer factor levels at over 40% for multiple days of the week. ALTUVIIIO's higher factor levels were associated with lower bleed risk, and the once-weekly dosing would allow us to schedule our week around a single infusion time.
Jack started ALTUVIIIO in October of 2024, and his dosing schedule is every Wednesday. We’ve found a treatment routine that works for Jack. We’re doing well and enjoying life. As Jack gets older, we want to ensure that he sticks to his treatment plan and keeps his joints safe. He wants to be a professional runner one day and have a career in sports, and we want him to have everything he needs to stay focused on that goal. Each person’s experience may be different, so it’s important to work with your doctor to find a treatment plan that is right for you. As for us, we’re glad we switched.”

ALTUVIIIO® [antihemophilic factor (recombinant), Fc-VWF-XTEN fusion protein-ehtl] is an injectable medicine that is used to control and reduce the number of bleeding episodes in people with hemophilia A (congenital Factor VIII deficiency).
Your healthcare provider may give you ALTUVIIIO when you have surgery.
What is the most important information I need to know about ALTUVIIIO?
Do not attempt to give yourself an injection unless you have been taught how by your healthcare provider or hemophilia center. You must carefully follow your healthcare provider’s instructions regarding the dose and schedule for injecting ALTUVIIIO so that your treatment will work best for you.
Who should not use ALTUVIIIO?
You should not use ALTUVIIIO if you have had an allergic reaction to it in the past.
What should I tell my healthcare provider before using ALTUVIIIO?
Tell your healthcare provider if you have had any medical problems, take any medications, including prescription and non-prescription medicines, supplements, or herbal medicines, are breastfeeding, or are pregnant or planning to become pregnant.
What are the possible side effects of ALTUVIIIO?
You can have an allergic reaction to ALTUVIIIO. Call your healthcare provider or emergency department right away if you have any of the following symptoms: difficulty breathing, chest tightness, swelling of the face, rash, or hives.
Your body can also make antibodies called “inhibitors” against ALTUVIIIO. This can stop ALTUVIIIO from working properly. Your healthcare provider may give you blood tests to check for inhibitors.
The common side effects of ALTUVIIIO are headache and joint pain.
These are not the only possible side effects of ALTUVIIIO. Tell your healthcare provider about any side effect that bothers you or does not go away.
