Advanced fibrosis was present in 51% and 27% had prior PR treatment. The IL28B genotype distribution was 38% CC, 50% CT and 12% TT. HCV Genotype distribution

comprised 68% 1a, 27% 1b and 5% 6C-1. 50% were eligible for response guided therapy. 54% of the BOC group and 37% of the TVR group had completed the prescribed treatment course at the time of submission. Baseline characteristics were comparable between both groups. Table 1 presents an interim analysis of virological responses and early discontinuation rates for each drug. Virological responses were consistently lower in cirrhotic patients at all time-points for both drugs. 37/153 (24%) stopped treatment early, 14% due to treatment futility and 10% due to adverse events. Early discontinuation rates were higher in cirrhotic patients. There was one death related to infection.

Further analysis of treatment-related morbidity is presented separately. Table 1 Conclusion: This ABC294640 price study is the first real-world study of clinical experience with TVR and BOC in Australia. The patient cohort was notable for a high ratio of “hard-to-cure” characteristics, including advanced liver fibrosis. Despite this, interim virological response rates were acceptable. “
“Tenofovir disoproxil fumarate (TDF) has demonstrated high antiviral efficacy in treatment-naive patients with chronic hepatitis B virus (HBV) infection but experience in nucleoside/nucleotide analogue (NA)-experienced patients is limited. In this retrospective multicenter Trametinib supplier study we therefore second assessed the long-term efficacy of TDF monotherapy in patients with prior failure or resistance to different NA treatments. Criteria for inclusion were HBV DNA levels >4.0 log10 copies/mL at the start and a minimum period of TDF therapy for at least 6 months. In all, 131 patients (mean age 42 ± 12 years, 95 male, 65% hepatitis B e antigen [HBeAg]-positive) were eligible. Pretreatment consisted of either monotherapy with lamivudine (LAM; n = 18), adefovir (ADV; n = 8), and sequential LAM-ADV

therapy (n = 73), or add-on combination therapy with both drugs (n = 29). Three patients had failed entecavir therapy. Resistance analysis in 113 of the 131 patients revealed genotypic LAM and ADV resistance in 62% and 19% of patients, respectively. The mean HBV DNA level at TDF baseline was 7.6 ± 1.5 log10 copies/mL. The overall cumulative proportion of patients achieving HBV DNA levels <400 copies/mL was 79% after a mean treatment duration of 23 months (range, 6–60). Although LAM resistance did not influence the antiviral efficacy of TDF, the presence of ADV resistance impaired TDF efficacy (100% versus 52% probability of HBV DNA <400 copies/mL, respectively). However, virologic breakthrough was not observed in any of the patients during the entire observation period. Loss of HBeAg occurred in 24% of patients and HBsAg loss occurred in 3%. No significant adverse events were noticed during TDF monotherapy.
