About Chronic Hepatitis C Patients and Thrombocytopenia
Approximately 4.2 million people in the U.S. have chronic hepatitis C, the most common blood-borne virus. It is estimated that up to 3.5% of these patients have platelet counts <75,000/µL, which could make them ineligible to start or maintain their interferon-based therapy.
Eltrombopag, marketed under the brand names PROMACTA
in the U.S. and Revolade
in Europe and Rest-of-World, is a thrombopoietin receptor agonist approved in 90 countries around the world as a treatment for thrombocytopenia in patients with chronic immune (idiopathic) thrombocytopenic purpura (ITP).
In the United States, PROMACTA
is already indicated for the treatment of thrombocytopenia in patients with chronic ITP who have had an insufficient response to corticosteroids, immunoglobulins or splenectomy.
