Approximately 25,000 people living in the US with hemophilia A, a rare blood disorder, may share a diagnosis, but their experiences can vary based on unmet needs and treatment challenges.1,2 Hemophilia A causes a person's blood to not clot properly, which can result in spontaneous bleeding, joint damage, and chronic pain.1 Hemophilia requires lifelong disease management, so treatment goals may evolve over time.1,2 For Chayse and Harrison, changing to the number one most switched to factor VIII replacement for hemophilia A helped them achieve their goals.*

Chayse: Easing the Treatment Burden
Diagnosed during his childhood, Chayse used the same factor treatment for over two decades. At seven years old, he learned to self-infuse at a hemophilia day camp, which gave him the confidence to explore his passion for music.
Passion turned profession, Chayse realized his treatment schedule was becoming a burden on his life as a musician. In total, he infused himself over 5,000 times - 180 times a year on average, which led him to consider a new treatment plan that offered a simpler routine without compromising bleed protection.
Chayse met with a Community Resource and Education Manager at Sanofi and learned about ALTUVIIIO® [antihemophilic factor (recombinant), Fc-VWF-XTEN fusion protein-ehtl], an injectable medicine that is used to control and reduce the number of bleeding episodes in people with hemophilia A.3 Chayse was excited about the prospect of a once-weekly treatment that keeps factor VIII activity levels near normal (> 40%) for multiple days of the week.3 After speaking to his doctor, they decided ALTUVIIIO would be a great fit and Chayse made the switch.
"When I realized what that infusion schedule could mean for my daily life, and my veins, I knew I wanted to try ALTUVIIIO," Chayse said.
Since starting on ALTUVIIIO in January 2024, Chayse's treatment burdens have eased. He doesn't need to infuse himself as often, and he no longer has to worry about transporting and packing as many doses of factor while traveling between treatments. Today, he has more time to focus on performing, teaching music, playing golf, or watching movies with his wife, Katie.
In a clinical study of adults and adolescents with hemophilia A, ALTUVIIIO prophylaxis resulted in 0.7 mean bleeds per year.†,‡
"Using ALTUVIIIO has simplified my routine, and the peace of mind knowing that I'm covered for longer has made me so happy," Chayse emphasized.
†Based on treated bleeds.
‡159 adults and adolescents with severe hemophilia (aged 12 years and older) were enrolled in the XTEND-1 study; 133 people were in Group 1 and switched to ALTUVIIIO prophylaxis from prior prophylaxis therapy. Efficacy of prophylaxis was evaluated in 128 of these patients.

Harrison and Ashley: Switching Therapies to Live a Fulfilled Childhood
When Ashley was pregnant with Harrison, she knew there was a high possibility of her son having hemophilia A as it runs in her family. A mom of three boys, two of them, including now five-year-old Harrison, are diagnosed with severe hemophilia A.
At the time, Harrison was treated with non-factor prophylaxis three times a week and supplemented with factor for breakthrough bleeds. Considering new options, Ashley wanted to ensure his treatment provided stable bleed protection without compromising his childhood.
"We wanted to limit how frequently he was getting hurt without stopping him from being the funny, sweet kid who loves to sing and play T-ball," Ashley said.
Ashley was at a conference where she listened in on a presentation on ALTUVIIIO. Interested to learn more, Ashley and Harrison spoke to his hematologist about the treatment and decided to try it for her son.
Since starting on ALTUVIIIO in 2023, Harrison has not experienced any breakthrough bleeding all while having a more efficient treatment schedule, allowing him to enjoy his favorite activities.
In a clinical study of children under 12 years of age with hemophilia A, ALTUVIIIO prophylaxis resulted in 0.6 mean bleeds per year.†,§
"Switching was worth it. We don't worry about supplementing with factor like we used to," Ashley said.
†Based on treated bleeds.
§ALTUVIIIO was studied in the XTEND-Kids study. The primary goal of the study was to determine whether or not children under 12 years of age developed inhibitors to ALTUVIIIO. 0 inhibitors were detected. Efficacy of prophylaxis was evaluated in 72 of these patients.
Starting a New Chapter with ALTUVIIIO
Before starting ALTUVIIIO, their doctors helped them understand the benefits of switching to ALTUVIIIO and its most common side effects, including headache and joint pain.3 Since switching, Chayse and Harrison have responded well to treatment, with effective bleed protection and higher-for-longer factor VIII levels. They feel peace of mind knowing their treatment schedules enable this level of bleed protection with once-weekly dosing.
"My hope is that I can encourage other people with hemophilia feel confident in taking some control over their own health. Finding a treatment plan that is the right fit for you is worth pursuing with your doctor," Chayse emphasized.
