Measure Type Secondary
Measure Title Early Virological Response (EVR), Partial EVR and Complete EVR by Week 12
Measure Description EVR: Undetectable HCV RNA <20 IU/mL or ≥2 log10 drop from pretreatment level, by Week 12 (a single last HCV RNA <20 IU/mL or ≥2 log10 drop from pretreatment level in the time window of Days 2 to 99). Partial EVR: Detectable HCV RNA but ≥2 log10 drop from pretreatment, by Week 12 (a single last HCV RNA detectable but ≥2 log10 drop from pretreatment in the time window of Days 2 to 99). Complete EVR: Undetectable HCV RNA <20 IU/mL, by Week 12 (a single last HCV RNA <20 IU/mL in the time window of Days 2 to 99). Patients without an HCV measurement by Week 12 were considered nonresponders.
Time Frame Week 12  
Safety Issue No
