Viral breakthrough was defined as having confirmed detectable HCV RNA levels (HCV RNA > LLOQ) on treatment after having previously had undetectable HCV RNA levels (HCV RNA < LLOQ) while on treatment. Viral relapse was defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) at end of treatment, but did not achieve an SVR. Data for this outcome measure were collected for participants in Part B only. |
