Rare blood disorders

Sanofi Market Access logo. Science. Innovation. Value.
A text callout highlighting some of the most serious unmet patient needs today are in the field of hematology; Our extended half-life factor replacement therapies for patients with hemophilia A and B were launched in 2014, becoming the first innovations in hemophilia management in ~20 years. Since then, they have been used to treat more than 3,500 people with hemophilia worldwide.

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

Exclusive near-term research in immune thrombocytopenia (ITP)

ITP is a heterogenous autoimmune disease characterized by isolated thrombocytopenia8

There are 3 distinct disease phases: newly diagnosed (within 3 months of diagnosis), persistent (between 3 and 12 months after diagnosis), and chronic (lasting 12 months or more after diagnosis).9

Bleeding occurs in ~60% of patients and significantly impacts quality of life.10,11

Half of patients with persistent or chronic ITP require treatment.12

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.
