Game changer: Hepatitis C drug may revolutionize treatment

Saint Louis University investigator reports findings in New England Journal of Medicine

The drug boceprevir helps cure hard-to-treat hepatitis C, says Saint Louis University investigator Bruce R. Bacon, M.D., author of the March 31 New England Journal of Medicine article detailing the study's findings.

The results, which were first reported at the 61st annual meeting of the American Association for the Study of Liver Disease's last November, offer a brighter outlook for patients who have not responded to standard treatment.

Bacon, who is professor of internal medicine at Saint Louis University School of Medicine and co-principal investigator of the HCV RESPOND-2 study, studied the protease inhibitor boceprevir and found that it significantly increased the number of patients whose blood had undetectable levels of the virus.

"These findings are especially significant for patients who don't respond to initial treatment," said Bacon. "When the hepatitis C virus is not eliminated, debilitating fatigue and more serious problems can follow."

Hepatitis C is caused by a virus that is transmitted by contact with blood. The infection may initially be asymptomatic, but for patients who develop chronic hepatitis C infection, inflammation of the liver may develop, leading to fibrosis and cirrhosis (scarring of the liver), as well as other complications including liver cancer and death.

The prognosis varies for patients with chronic hepatitis C. With the current standard therapy, about half fully recover after an initial course of peginterferon and ribavirin anti-viral therapy that may last from six months to a year.

The remaining patients, known as non-responders, may improve with initial treatment but the virus is not eliminated, or may not respond to treatment at all. For this group, the only current option is to re-treat patients with the same or similar drugs, which increases the likelihood of severe treatment side-effects. In addition, researchers have found that the success of treatment depends on the major strain, or genotype, of hepatitis C that a patient has.

The HCV RESPOND-2 study looked at 403 patients with chronic hepatitis C infections with genotype one, the most difficult strain of the virus to treat, who still had significant levels of the virus after being treated with peginterferon and ribavirin, the standard hepatitis C treatment.

"These results are very exciting," Bacon said. "In this study, boceprevir helped cure significantly more patients in 36 weeks of therapy than did treatment with peginterferon and ribavirin alone."

A second study, HCV SPRINT-2, examined patients with hepatitis C with genotype one who had not yet been treated with the standard treatment. They, too, responded well to the drug.

Bacon calls the progress made in treating hepatitis C remarkable.

"We've gone from the discovery of the virus in 1989 to where we are now, 22 years later, when we have the ability to cure a large majority of those with hepatitis C," Bacon said. "It's a true success story."

"Drugs like boceprevir are going to revolutionize care of those with hepatitis C."

The clinical trial was funded by Merck, which is seeking FDA approval for the drug.

Established in 1836, Saint Louis University School of Medicine has the distinction of awarding the first medical degree west of the Mississippi River. The school educates physicians and biomedical scientists, conducts medical research, and provides health care on a local, national and international level. Research at the school seeks new cures and treatments in five key areas: cancer, liver disease, heart/lung disease, aging and brain disease, and infectious disease.

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
