Treated subjects (N=631) had a median age of 52 years (range: 18 to 70); 54.5% were male; 5.4% were Black; 16.2% had a body mass index of at least 30 kg/m²; 15.2% had a history of depression or bipolar disorder; 69.3% had IL28B non-CC genotype; 79.1% had baseline HCV RNA levels of at least 800,000 IU/mL; 15.4% had portal fibrosis (F2) and 8.7% had bridging fibrosis (F3); 67.7% had HCV genotype 1a infection; 32.3% had HCV genotype 1b infection.

Table 7 shows the SVR12 rates for genotype 1-infected, treatment-naïve subjects receiving Exviera and ombitasvir/paritaprevir/ritonavir in combination with ribavirin for 12 weeks in SAPPHIRE-I.

CI = confidence interval, VF = virologic failure

a. On-treatment VF was defined as confirmed HCV ≥ 25 IU/mL after HCV RNA < 25 IU/mL during treatment, confirmed 1 log₁₀ IU/mL increase in HCV RNA from nadir, or HCV RNA persistently ≥ 25 IU/mL with at least 6 weeks of treatment.

b. Relapse was defined as confirmed HCV RNA ≥ 25 IU/mL post-treatment before or during SVR12 window among subjects with HCV RNA less than 25 IU/mL at last observation during at least 11 weeks of treatment.

c. Other includes subjects not achieving SVR12 but not experiencing on-treatment VF or relapse (e.g. missing HCV RNA values in the SVR12 window).

No subjects with HCV genotype 1b infection experienced on-treatment virologic failure and one subject with HCV genotype 1b infection experienced relapse.

PEARL-III – genotype 1b, treatment-naïve

PEARL-III was a randomised, global multicentre, double-blind, controlled trial conducted in 419 treatment-naïve adults with genotype 1b chronic hepatitis C virus infection without cirrhosis. Subjects were randomised in a 1:1 ratio to receive Exviera and ombitasvir/paritaprevir/ritonavir with or without ribavirin for 12 weeks of treatment.

Treated subjects (N=419) had a median age of 50 years (range: 19 to 70); 45.8% were male; 4.8% were Black; 16.5% had a body mass index of at least 30 kg/m²; 9.3% had a history of depression or bipolar disorder; 79.0% had IL28B non-CC genotype; 73.3% had baseline HCV RNA of at least 800,000 IU/mL; 20.3% had portal fibrosis (F2) and 10.0% had bridging fibrosis (F3).

Table 8 shows the SVR12 rates for genotype 1b-infected, treatment-naïve subjects who received Exviera and ombitasvir/paritaprevir/ritonavir with or without ribavirin for 12 weeks in PEARL III. In this study, Exviera and ombitasvir/paritaprevir/ritonavir without ribavirin had similar SVR12 rates (100%) compared to Exviera and ombitasvir/paritaprevir/ritonavir with ribavirin (99.5%).

b. Relapse was defined as confirmed HCV RNA ≥ 25 IU/mL post-treatment before or during SVR12 win
