dow 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 and ombitasvir/paritaprevir/ritonavir with ribavirin.
Table 9. SVR12 for genotype 1a-infected treatment-naïve subjects in PEARL IV
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).
Clinical trials in peginterferon+ribavirin-experienced adults
SAPPHIRE-II – genotype 1, peginterferon+ribavirin-experienced
SAPPHIRE-II was a randomised, global multicentre, double-blind, placebo-controlled trial conducted in 394 subjects with genotype 1 chronic hepatitis C virus infection without cirrhosis who did not achieve SVR with prior treatment with pegIFN/RBV. Exviera and ombitasvir/paritaprevir/ritonavir in combination with ribavirin was given for 12 weeks of treatment. Subjects randomised to the placebo arm received placebo for 12 weeks, after which they received Exviera and ombitasvir/paritaprevir/ritonavir in combination with ribavirin for 12 weeks.
Treated subjects (N=394) had a median age of 54 years (range: 19 to 71); 49.0% were prior pegIFN/RBV null responders; 21.8/% were prior pegIFN/RBV partial responders; and 29.2% were prior pegIFN/RBV relapsers; 57.6% were male; 8.1% were Black; 19.8% had a body mass index of at least 30 kg/m2; 20.6% had a history of depression or bipolar disorder; 89.6% had IL28B non-CC genotype; 87.1% had baseline HCV RNA levels of at least 800,000 IU per mL; 17.8% had portal fibrosis (F2) and 14.5% had bridging fibrosis (F3); 58.4% had HCV genotype 1a infection; 41.4% had HCV genotype 1b infection.
