Abstract

Disclosed herein are a composition and unit dosage form for the treatment of hepatitis C virus (HCV) infection comprising GS-7977 and at least one pharmaceutically acceptable excipient, as well as methods for making said composition and unit dosage form. Also disclosed herein is a method of treating a subject, preferably a human, infected with hepatitis C virus, said method comprising administering to the subject for a time period an effective amount of GS-7977 and an effective amount of ribavirin. In one aspect, the method comprises administering to the subject an interferon-free treatment regimen comprising an effective amount of GS-7977 and an effective amount of ribavirin. In a particular aspect, the method is sufficient to produce an undetectable amount of HCV RNA in the subject for at least 12 weeks after the end of the time period.

Claims

1-50. -50. (canceled)

51. A method of treating a human infected with hepatitis C virus comprising administering to the human a composition comprising:

a) a crystalline compound having the structure;

52. The method according to claim 51, wherein the method comprises administering a daily dose of about 400 mg of the crystalline compound.

53. The method according to claim 52, wherein the method comprises administering a daily dose of about 1000 mg to about 1200 mg of ribavirin.

54. The method according to claim 51, wherein the method comprises administering the crystalline compound to the human once, twice, three times or four times daily.

55. The method according to claim 51, wherein the method comprises administering ribavirin to the human once, twice, three times or four times daily.

56. The method according to claim 51, wherein the method comprises administering the crystalline compound to the human once daily.

57. The method according to claim 56, wherein the method comprises administering ribavirin to the human twice daily.

58. The method according to claim 51, wherein the method comprises administering a daily dose of about 400 mg of the crystalline compound and a daily dose of about 1000 mg to about 1200 mg of ribavirin.

59. The method according to claim 58, wherein the method comprises administering the crystalline compound to the human once daily and administering ribavirin to the human twice daily.

60. The method of claim 51, wherein the method comprises administering the crystalline compound and ribavirin to the human concurrently or alternatively.

61. The method of claim 51, wherein the method comprises administering the crystalline compound and ribavirin to the human orally.

62. The method of claim 61, wherein the method comprises administering the crystalline compound in a tablet or a capsule form.

63. The method of claim 62, wherein the method comprises administering ribavirin in a tablet or capsule form.
