Abstract: The present invention relates to therapeutic combinations comprising faldaprevir, sofosbuvir, ledipasvir and, optionally, ribavirin, and methods of using such therapeutic combinations for treating HCV infection in a patient.

Abstract: Isolated porcine hepatocytes, isolated populations of such hepatocytes and methods for using the hepatocytes to treat subjects with disorders characterized by insufficient liver function are described. The porcine hepatocytes can be either hepatocytes isolated from adult, immature, or embryonic swine. The porcine hepatocytes can be modified to be suitable for transplantation into a xenogeneic subject, for example, by altering an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in the subject (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof). The isolated porcine hepatocytes of the invention can be used to treat disorders characterized by insufficient liver function by administering the hepatocytes to a subject having such a disorder.

Abstract: Methods for identifying hepatitis C virus (HCV)-infected subjects responsive to treatment for HCV infection or unlikely to respond to treatment for HCV infection are described. The level of Th2 cytokines in the subject during treatment serves as an indicator of whether the subject is likely to respond to treatment for HCV, e.g., interferon treatment. An elevated level of at least one Th2 cytokine during treatment indicates that an HCV-infected subject is unlikely to respond to a treatment for HCV. A decreased level of at least one Th2 cytokine indicates that an HCV-infected subject is responsive to a treatment for HCV. In a preferred embodiment, IL-10 levels are detected to identify subjects responsive to or unlikely to respond to interferon treatment.
