Protection your way: Sanofi’s commitment to personalized care for hemophilia A and B
A tailored therapeutic approach for hemophilia A and B, aimed at minimizing treatment burden and enhancing disease management
In the United States, approximately 30,000 to 33,000 males have hemophilia A or B, with over 40% having a severe form of the condition.1*
Patients with hemophilia have insufficient clotting factor proteins, resulting in inadequate thrombin generation, leading to excessive and longer-than-usual bleeding after physical injury. Individuals with hemophilia may also experience spontaneous bleeding into their muscles, organs, and joints.2-4

Acquired thrombotic thrombocytopenic purpura (aTTP)
aTTP is a rare, life-threatening blood disorder characterized by the formation of small blood clots (microthrombi) in the body’s smallest blood vessels, leading to low platelet count (thrombocytopenia), destruction of red blood cells (hemolytic anemia), and organ damage.5-7
*Although the bleeding disorder primarily affects males, females can also have hemophilia.2
†Approved in 2023.
‡Approved in 2014.
Exclusive near-term research in immune thrombocytopenia (ITP)
ITP is a heterogenous autoimmune disease characterized by isolated thrombocytopenia8

The heterogenous nature of ITP creates the need for multiple treatment options
There is an unmet need for an effective treatment option that has a positive impact on patient quality of life and a favorable safety profile.
