측정값 설명
기간
Percentage of Participants With Sustained Viral Response 12 Weeks After Last Planned Dose of Study Drug (SVR12)
기간: 12 weeks after last planned dose of study drug (up to Week 60)
SVR12 was defined as an undetectable Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels (<lower limit of quantification) at 12 weeks after last planned dose of study treatment. The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of quantification was 25 international units per milliliter (IU/mL).
