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%).
Table 8. SVR12 for genotype 1b-infected treatment-naïve subjects in PEARL III
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).
PEARL-IV– genotype 1a, treatment-naïve
PEARL-IV was a randomised, global multicentre, double-blind, controlled trial conducted in 305 treatment-naïve adults with genotype 1a chronic hepatitis C virus infection without cirrhosis. Subjects were randomised in a 1:2 ratio to receive Exviera and ombitasvir/paritaprevir/ritonavir with or without ribavirin for 12 weeks of treatment.
Treated subjects (N=305) had a median age of 54 years (range: 19 to 70); 65.2% were male; 11.8% were Black; 19.7% had a body mass index of at least 30 kg/m2; 20.7% had a history of depression or bipolar disorder; 69.2% had IL28B non-CC genotype; 86.6% had baseline HCV RNA levels of at least 800,000 IU/mL; 18.4% had portal fibrosis (F2) and 17.7% had bridging fibrosis (F3).
Table 9 shows the SVR12 rates for genotype 1a-infected, treatment-naïve subjects who received Exviera and ombitasvir/paritaprevir/ritonavir with or without ribavirin for 12 weeks in PEARL IV. Exviera and ombitasvir/paritaprevir/ritonavir without ribavirin was not non-inferior to Exviera |
