11 No data concerning the potential for RGT with telaprevir in relapsed patients have been reported. The safety and tolerability profile of simeprevir/PR in the present study was generally similar to that of PR alone,42 with no additional treatment-related AEs reported. The improved virologic response rates achieved by addition of simeprevir to PR allowed a reduction in total treatment duration

for most patients, which significantly reduced exposure to PR and time with treatment-related side effects overall for simeprevir-treated compared with placebo-treated patients. AEs were generally mild and clinically manageable, with few grades 3/4 AEs or SAEs reported, and no patient discontinued simeprevir LDK378 nmr because of AEs. No increased incidence for simeprevir/PR compared with PR alone was seen for rash, pruritus, neutropenia, or anemia AEs, despite the fact that use of erythropoiesis-stimulating agents was not allowed in this study. These events were considered of clinical interest because an increased incidence

has been reported with boceprevir and telaprevir.11, 12, 13, 14 and 22 Mild and transient bilirubin increases were seen in simeprevir-treated patients; however, no concomitant increases in other laboratory liver parameters were observed. This finding may be associated with inhibition of bilirubin transporters OATP1B1 and MRP2 by simeprevir,43 although RBV-induced hemolysis Tideglusib also may cause bilirubin increases. The addition of simeprevir to PR did not increase patient-reported fatigue, productivity impairment, or activity impairment beyond what was observed in patients who received PR selleck chemicals llc alone, but did shorten the duration of these treatment-related problems. In conclusion, the addition of simeprevir 150 mg once daily to PR substantially improved SVR rates in HCV genotype 1–infected patients who

had relapsed after previous IFN-based therapy, irrespective of IL28B genotype, METAVIR score, HCV 1 subtype, or the presence of baseline polymorphisms. The majority of simeprevir-treated patients met RGT criteria, enabling a shorter, 24-week overall duration of PR treatment. The addition of simeprevir to PR generally was well tolerated, with safety and tolerability similar to PR alone. Ongoing studies are investigating simeprevir in both PegIFNα and IFN-free combinations, including all oral regimens.
