Meet Chris
“I’m 66 years old and I have severe hemophilia A. I’ve tried 7 different treatments over my lifetime, switching as new treatments have been developed. I know that switching treatments can be a hassle, and that it may feel easier to stay with what you have. I can understand questioning whether switching is worth the trouble, but I’ve learned: if there’s a treatment out there that can give me the results I want, it’s worth a discussion with my doctor to make a change.
Before ALTUVIIIO, I was on another prophylaxis treatment, infusing 3 times a week with a trough level of 2%. When I heard about ALTUVIIIO, I was really excited about the 48-hour half-life, and keeping my Factor VIII levels over 40% for most of the week with a once-a-week infusion. I talked to my hematologist and my Sanofi CoRe Manager about it, and decided to make the switch. Sanofi Patient Support Services made the process of starting ALTUVIIIO and navigating my insurance coverage seamless.
Infusing once a week has been a great change for me. I feel really good about the bleed protection I have now, and I haven't had any bleeds while on ALTUVIIIO. My test results have shown that my trough levels are around 10% on Day 7.
Remember that each person’s hemophilia treatment plan may differ, so you need to work with your doctor to find a treatment plan that is right for you. As for me, I’m glad I switched.
Being on top of and consistent with my treatment and health is very important to me—especially at my age. I’m at a place where if I don’t stay active, then I’m not going to be active. So I try to get to the gym regularly, and that helps me have the mobility I need when I’m traveling, hiking, skiing, or participating in my local theater group. I couldn’t do any of this if I didn’t take my health and treatment seriously.
When I was younger, information and treatment options were limited. Now, we have resources and options. I want to encourage each of you to continue connecting with the hemophilia community, and if you aren’t happy with your current treatment, talk to your doctor about finding a treatment that’s right for you.”

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.
