Summary

Hepatitis C virus (HCV) is an enveloped, single strand, positive sense RNA flavivirus. Infection by HCV is typically chronic, although an estimated \~10-20% may spontaneously clear the virus. HCV affects between 1.3 - 2 billion individuals, or 2-3% of the global population. HCV has a seroprevalence of approximately 1% in developed countries such as the US and Korea. Chronic HCV infection leads to hepatic fibrosis and cirrhosis. This Phase I study will evaluate the safety, tolerability and immunogenicity of GLS-6150 administered intradermally (ID) followed by electroporation at 1.0 mg and 2.0 mg/dose assessing 3 and 4-dose regimens.

Detailed description

HCV-003 will assess the safety and immunogenicity of GLS-6150 in those previously treated for HCV infection and who have achieved a sustained virologic response (SVR). This study will provide information as to whether GLS-6150 may be useful to prevent re-infection for those successfully cleared of HCV infection. GLS-6150 is a DNA plasmid vaccine that expresses the NS3/4A gene of HCV, NS4B gene of HCV, the NS5A gene of HCV and IL-28B. GLS-6150 will be administered at one of two dose levels (1 mg or 2 mg) and given as a 2 or 3 vaccination priming regimen with a boost vaccination given at 6 months. Immune T cell and serologic responses will be determined after each dose.
