Eltrombopag effective for hepatitis C patients with low blood-platelet counts

It's estimated that 4 million people in the U.S. and 170 million worldwide carry the hepatitis C virus. HCV is transmitted primarily by blood and blood products. The majority of infected individuals have either received blood transfusions prior to 1990 (when screening of the blood supply for HCV was implemented) or have used intravenous drugs. More rarely, it can also be transmitted through sexual intercourse and perinatally (mother to baby).

The virus causes inflammation and scarring in the liver, and while it is curable in about half of those who have it, it can lead to significant liver damage, liver cancer and death in others. HCV infection is a common cause of cirrhosis and the most common reason for a liver transplant.

With other eltrombopag findings, NewYork-Presbyterian/Weill Cornell's Dr. James Bussel led research, also reported in the New England Journal of Medicine, finding the platelet growth factor successfully increased platelet counts and decreased bleeding in patients with Immune Thrombocytopenic Purpura (ITP), an autoimmune disease that dramatically reduces the number of platelets in their blood. (Dr. Bussel is an Advisory Board Member for GlaxoSmithKline; has received research grant support, lecture fees, and consulting fees from GlaxoSmithKline; and reports equity ownership in the company.)

The current study was sponsored by GlaxoSmithKline, which is developing eltrombopag. Eltrombopag (marketed as Promacta in the U.S. and Revolade in Europe) is an investigational oral, non-peptide platelet growth factor that induces the proliferation and differentiation of cells to produce platelets. While other drugs that restore normal platelet functions are infusions or injections, eltrombopag is a once-a-day pill.

The study's principal investigator was Dr. John McHutchison, of the Duke Clinical Research Institute, Durham, N.C. Additional participating institutions included Royal Free Hospital
