Study Arms:
- Part 1 Grazoprevir 50 mg + Elbasvir (Type: EXPERIMENTAL): Non-cirrhotic participants take 50 mg grazoprevir in combination with 50 mg elbasvir by mouth (p.o.) once daily (q.d.) for 12 weeks during the blinded period of Part 1 and are followed-up for 24 weeks during the open-label period of Part 1.
- Part 1 Grazoprevir 100 mg + Elbasvir (Type: EXPERIMENTAL): Non-cirrhotic participants take 100 mg grazoprevir in combination with 50 mg elbasvir p.o. q.d. for 12 weeks during the blinded period of Part 1 and are followed-up for 24 weeks during the open-label period of Part 1.
- Part 2 Non-cirrhotic Immediate: Grazoprevir + Elbasvir (Type: EXPERIMENTAL): Non-cirrhotic participants take grazoprevir (50 mg or 100 mg dose selected from Part I) and 50 mg elbasvir p.o. q.d. for 12 weeks during the blinded period of Part 2 and are followed-up for 24 weeks during the open-label period of Part 2.
- Part 2 Non-cirrhotic Deferred: Placebo► Grazoprevir + Elbasvir (Type: PLACEBO_COMPARATOR): Non-cirrhotic participants take dose-matched placebo p.o. q.d. for 12 weeks during the blinded period of Part 2 followed by a 4-week follow-up. Afterwards, participants take grazoprevir (50 mg or 100 mg dose selected from Part I) and 50 mg elbasvir p.o. q.d. for 12 weeks and are followed-up for 24 weeks during the open-label period of Part 2.
- Part 2 Cirrhotic: Grazoprevir + Elbasvir (Type: EXPERIMENTAL): Cirrhotic participants take grazoprevir (50 mg or 100 mg dose selected from Part 1) and 50 mg elbasvir p.o. q.d. for 12 weeks during the blinded period of Part 2, and are followed-up for 24 weeks during the open-label period of Part 2.
