- Methods for treating hepatitis C
-
Methods of treating hepatitis C are provided comprising using a therapeutically effective amount of at least one novel hepatitis C (“HCV”) protease inhibitor or, alternatively, at least one antiviral or immuno-modulating HCV agent, which is not an HCV protease inhibitor, for a first treatment period. Subsequently, a combination of the at least one novel hepatitis C (“HCV”) protease inhibitor and the at least one antiviral or immuno-modulating HCV agent are administered in a therapeutically effective amount for a second treatment period. The methods are provided for treating a wide variety of diseases, disorders and symptoms associated with hepatitis C virus by modulating the activity of HCV protease (for example HCV NS3/NS4a serine protease) in a subject.

- METHOD OF TREATING INTERFERON NON-RESPONDERS USING HCV PROTEASE INHIBITOR
-
A method of treating, preventing or ameliorating one or more symptoms associated with hepatitis C virus (HCV) in a patient in whom either the HCV is of Genotype 1 and/or the patient was previously treated with interferon and the previous interferon therapy was ineffective to treat the one or more symptoms associated with HCV, comprising administering to such a patient an effective amount of at least one compound of formulae I-XXVI of which the structural formula (I) is exemplary or a pharmaceutically acceptable salt, solvate or ester thereof. Optional combined administration of said at least one compound with an interferon or pegylated interferon and/or ribaviron is also contemplated.

- ASYMMETRIC DOSING METHODS
-
A method of treating, preventing or ameliorating one or more symptoms of hepatitis C, or inhibiting cathepsin activity, in a subject is provided, in which at least one compound (e.g., a HCV protease inhibitor) is administered in one or more discrete dosages over a twenty-four hour time interval in an asymmetric pattern as to dosage amount and/or timing of dosage, wherein the at least one compound is selected from the group consisting of compounds of Formulae I-XXVI, described herein. Methods of modulating the activity of hepatitis C virus protease in a subject are also provided. Asymmetric dosing as to amount of dose and/or timing of dose permits adjustment of dosing to accommodate variations in drug metabolism and/or viral activity caused by viral cell division or a patient's circadian rhythms, thus delivering the maximum amount of dose at the time or times it is most effective.

- Administration of HCV protease inhibitors in combination with food to improve bioavailability
-
Methods of treating, preventing or ameliorating one or more symptoms of hepatitis C in a subject comprising the step of administering at least one HCV protease inhibitor in combination with food are provided. Also provided are methods of increasing bioavailability of an HCV protease inhibitor and methods of increasing serum levels of an HCV protease inhibitor in a subject. All methods comprise adminstering at least one HCV protease inhibitor in combination with food, the at least one HCV protease inhibitor selected from the group consisting of compounds of Formulae I-XXVI, described herein. Administration of compounds of the present invention in combination with food provides improved bioavailability and increased peak serum levels of the compounds as compared to administration without food.

- METHOD FOR MODULATING ACTIVITY OF HCV PROTEASE THROUGH USE OF A NOVEL HCV PROTEASE INHIBITOR TO REDUCE DURATION OF TREATMENT PERIOD
-
Methods are provided for using at least one novel hepatitis C ("HCV") protease inhibitor in combination with at least one antiviral and/or immunomodulatory agent, which is different from the at least one HCV protease inhibitor, for treating a wide variety of diseases or disorders associated with hepatitis C virus by modulating the activity of HCV protease (for example HCV NS3/NS4a serine protease) and reducing HCV viral load in a subject in a reduced treatment period. With the present invention, a hepatitis C viral load is reduced in a subject to a concentration of less than 6?10-5 HCV virions per milliliter of plasma in a time period of less than or equal to about 24 weeks. With the present invention, a hepatitis C viral production is suppressed with an effectiveness in a range of 0.7 to 0.997. "
