The Number of Participants With Viral Breakthrough
Ramy czasowe: Day 1 until end of treatment (EOT [Week 24 or 48])
|
Viral breakthrough was defined as a confirmed increase of greater than 1 log10 IU/mL in plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels from the lowest level reached or a confirmed value of plasma HCV RNA of > 2.0 log10 IU/mL in particpants whose plasma HCV RNA level had previously been below 1.2 log10 IU/mL detectable or undetectable during the treatment period.
The table below shows that no viral breakthrough was noted in any participants during the treatment period of the study.
