5 kPa). Virological response (VR) was defined as undetectable HCV RNA using a sensitive quantitative PCR assay. Results: 407 patients were included in this interim analysis, of whom 308 patients had end of treatment data and 157 had week 12 follow up data. The majority were male (68%) and Caucasian (90%), with mean age of 51 years. Cirrhosis was present in 24% (Child-Pugh A) and 55% had prior PR treatment. HCV genotype 1 distribution was 53% 1a, 16% 1b, 3% 1a/1b, and 28% undifferentiated. IL28B genotype distribution was 20% CC, 35% CT, 7% TT and 38% unknown. Anaemia

(Hb <10g/dL) occurred in 42% and Hb reduction >3g/dL in 70%. RBV dose reduction was needed in 33% and blood transfusion in 16%. Infections were rare and there were no deaths. Early treatment discontinuation TSA HDAC purchase occurred in 24%, more often due to treatment futility (14%) than adverse events (10%). A sustained VR at week 12 post-treatment (SVR12) was achieved in 82% (95/115) of non-cirrhotics http://www.selleckchem.com/products/VX-809.html and 66% (28/42) of cirrhot-ics. In a multivariate logistic regression analysis, presence of cirrhosis (OR 2.75, p= 0.03, CI 1.1-6.91) and non-IL28B CC (OR 11.73, p= 0.024, CI 1.39-98.69) were associated with failure to achieve SVR12. Conclusion: In this first multi-centre real-world study of clinical experience with BOC in Australia, treatment of a large well-compensated cohort with BOC demonstrated acceptable efficacy and safety data that were comparable to that

in registration studies. Disclosures: Miriam T. Levy – Advisory Committees or Review Panels: Gilead; Grant/Research Support: Gilead; Speaking and Teaching: Roche Stuart K.

Warner Introduction Single-nucleotide polymorphisms (SNPs) located in the DDRGK1 gene have been 上海皓元医药股份有限公司 associated with thrombocytopenia during peginterferon (peg-IFN) and ribavirin (RBV) treatment among Japanese patients with chronic

hepatitis C virus (HCV) infection. Methods We assessed the relation between SNPs in the DDRGK1 gene and treatment-induced thrombocytopenia in Caucasian patients with chronic HCV infection. All consecutive patients with chronic HCV infection treated with peg-IFN and RBV from 2000 to 2009 were included when serum was available for genetic testing. The SNPs rs11697186 (DDRGK1), rs1127354 (ITPA-1) and rs7270101 (ITPA-2) were determined. Decline in platelet counts (PLT, x109/L) and hemoglobin (Hb, mmol/L) was assessed at week 4 (+/−7 days) of treatment. Results In 226 Caucasian patients serum was available for genetic testing. Median age was 45 (IQR 39-50) years, 151 (67%) patients were male, 111 (49%) had HCV genotype 1, and 43 (19%) had cirrhosis. DDRGK1 and ITPA-1 were in strong linkage-disequilibrium (r2=0.901).
