New Drug May Help Fight Hepatitis C

continued...

They caution, however, that peginterferon may not benefit all patients. Even this improved formulation may be insufficient against the highly-interferon resistant genotype 1 hepatitis C strain carried by about 75% of infected patients in the U.S. In both studies, the response rate was much lower for those with this resistant strain than it was for those with other strains of the virus.

Also, Schafer tells WebMD, more research is needed to determine whether black patients, who were underrepresented in these studies despite comprising a large proportion of those with hepatitis C, will have a similar rate of response as other racial and ethnic groups.

Peginterferon is not yet on the market, but FDA approval is pending. -->
