ALTUVIIIO® [Antihemophilic Factor (Recombinant), Fc-VWF-XTEN Fusion Protein-ehtl] logo
Peer Morgan with quote “I did my research on ALTUVIIO, and I learned that a woman was part of the clinical trial–the first woman in a clincal trial for hemophilia. That was a big deal for me. I felt seen.”

Meet Morgan

"My mom has a family history of hemophilia, and she knew she was a carrier, so she asked my doctor to test my factor levels. When the test results came back, I was diagnosed with severe hemophilia A. My identical twin sister, Madison, was also tested, but her factor levels indicated she didn’t have severe hemophilia. Fun fact: we were written about in a hematology journal as the first case of identical twins where one was diagnosed with severe hemophilia and the other was not.

I often felt different because of my bleeding disorder. I felt less out of place when I spent time around other kids with hemophilia. My mom is an incredible advocate; from an early age, we were active in our bleeding disorder community.

For many years, I was on a recombinant factor. When I was around 22 years old, I went on a factor mimetic treatment and supplemented regularly with factor for bleeds. Then one day in May 2024, I woke up with the taste of blood in my mouth. I went to the doctor, and he said I needed a partial tonsillectomy. After the surgery, I kept bleeding because I didn’t have the factor I needed. I woke up in the ICU with a tube in my throat. My mom flew from her vacation in Aruba to Orlando to help advocate for me when I was unable to advocate for myself. I eventually got the factor I needed, but I was in the hospital for nearly 2 weeks.

I had my yearly appointment with my hematologist the day after I was discharged from the hospital. I learned that ALTUVIIIO is a once-weekly prophylaxis Factor VIII therapy, and that it was shown to keep factor levels higher for longer—over 40% for most of the week—in adults. I liked that I’d only have to infuse with ALTUVIIIO once a week and that it had a longer half-life. My mom went with me to the appointment, and we discussed ALTUVIIIO with my doctor. We agreed that ALTUVIIIO could be a good fit for me, and I started ALTUVIIIO in May 2024.

Some of my favorite activities are going to concerts and theme parks. At a recent concert, my favorite member of my favorite boy band walked to the edge of the stage at the end of a song and handed me his tambourine! When I have days where I don’t want to infuse, and think, ‘Why was I born with this condition?’—I’ll look at the tambourine hanging on my wall, and tell myself, ‘This is why I need to do my infusions. A bleed could potentially prevent me from taking part in experiences like this.’

As a woman with severe hemophilia A, I’ve often felt out of place. But my experiences taught me how meaningful it is to belong and to help create a feeling of belonging for others, too.”

INDICATION

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.

IMPORTANT SAFETY INFORMATION

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.

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.
