Hepatitis C is "inflammation of the liver in humans caused by hepatitis c virus, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown."[1]
Treatment
| Trial | Patients | Intervention | Comparison | Outcome | Results | |
|---|---|---|---|---|---|---|
| Intervention | Control | |||||
| ADVANCE Study[2] 2011 |
Previously untreated patients | telaprevir | peginterferon-ribavirin | HCV RNA 24 weeks after last treatment | 69% to 75% | 44% |
| REALIZE Study[3] 2011 |
Previously treated patients | telaprevir | peginterferon-ribavirin | HCV RNA 24 weeks after last treatment | 83% to 88% (prior reponse) 54% to 59% (prior partial response) 29% to 33% (prior non-response) |
24% (prior reponse) 15% (prior partial response) 5% (prior non-response) |
| SPRINT-2 study[4] 2011 |
Previously untreated patients | boceprevir | peginterferon-ribavirin | HCV RNA level | 59% to 66% | 21% |
| HCV RESPOND-2 study[5] 2011 |
Previously treated patients | boceprevir | peginterferon-ribavirin | HCV RNA level | 67% to 68% (nonblack patients) 42% to 53% (black patients) |
40% (nonblack patients) 23% (black patients) |
Two protease inhibitors, telaprevir and boceprevir may add benefit to standard therapy of genotype 1 infection with peginterferon and ribavirin. Telaprevir adds to peginterferon and ribavirin for previously treated[2] and untreated[3] patients. Boceprevir adds to peginterferon and ribavirin for previously treated[5] and untreated[4] patients.
