Compounds effective in inhibiting replication of Hepatitis C virus (“HCV”) are described. This invention also relates to processes of making such compounds, compositions comprising such compounds, and methods of using such compounds to treat HCV infection.
The present invention features solid compositions comprising a selected HCV inhibitor in an amorphous form. In one embodiment, the selected HCV inhibitor is formulated in an amorphous solid dispersion which comprises a pharmaceutically acceptable hydrophilic polymer and preferably a pharmaceutically acceptable surfactant.
