Telbivudine vs tenofovir in hepatitis B e antigen-negative chronic hepatitis B patients: OPTIMA roadmap study

AIM To make efficacy and safety comparison of telbivudineraodmap and tenofovir-roadmap in hepatitis B e antigen(HBe Ag)-negative chronic hepatitis B(CHB) patients.METHODS This was the first prospective, randomised, two-arm, open-label, non-inferiority study in HBe Ag-negative CHB patients that compared telbivudine and tenofovir administered as per roadmap concept. Patients were treated up to 24 wk and, depending on virologic response, continued the same therapy or received addon therapy up to 104 wk. Eligible patients received an additional 52 wk of treatment in the extension period(i.e., up to 156 wk). Patients who developed virologic breakthrough(VB) while on monotherapy also received add-on therapy. The primary efficacy endpoint was the rate of patients achieving hepatitis B virus(HBV) DNA 300 copies/m L at week 52. Secondary efficacy endpoints included the rates of HBV DNA 300 and 169 copies/m L, HBV DNA change from baseline, alanine aminotransferase normalisation, hepatitis B surface antigen(HBs Ag) loss, HBs Ag seroconversion, VB, and emergence of resistance at various timepoints throughout the study. Safety and estimated glomerular filtration rate(e GFR) were also analysed.RESULTS A total of 241 patients were randomised. Non-inferiority of telbivudine arm to tenofovir arm was demonstrated at week 52(± 7 d window), with over 91% of patients in each treatment arm achieving HBV DNA level 300 copies/m L. Both arms were similar in terms of key secondary efficacy variables at weeks 104 and 156. The percentage of patients achieving HBV DNA 300 copies/m L remained high and was similar in the telbivudine and tenofovir arms at both weeks 104 and 156. Over 82% of patients in both arms achieved alanine aminotransferase normalisation at week 52, and this percentage remained high at weeks 104 and 156. Telbivudine treatment progressively reduced serum HBs Ag levels from baseline while no change was reported in quantitative HBs Ag during therapy with tenofovir. Both treaments showed acceptable safety profiles. The telbivudine arm showed e GFR improvement unlike the tenofovir arm.CONCLUSION Efficacy was shown for both telbivudine-roadmap and tenofovir-roadmap regimens in HBe Ag-negative CHB patients over 156 wk. Telbivudine arm was associated with renal improvement.

Similar efficacy and safety of tenofovir in Asians and non-Asians with chronic hepatitis B

AIM:To compare the efficacy and safety of tenofovir disoproxil fumarate(TDF)in Asian and non-Asian chronic hepatitis B(CHB)patients.METHODS:The efficacy and safety of the initial 48wk of treatment with TDF was compared in a posthoc analysis of combined data from 217 Asians and299 non-Asians included in Studies 102 and 103and a post-approval,open-label trial(Study 123).Patient groups were compared according to baseline hepatitis B e antigen(HBe Ag)status and viral load.The main outcome measures included the proportion of patients who achieved a hepatitis B virus(HBV)DNA level400 copies/m L at Week 48 of treatment.Secondary measures included:HBV DNA and alanine aminotransaminase(ALT)levels over time;proportion of patients with normal ALT levels;proportion of patients with HBe Ag loss/seroconversion and proportion of patients with hepatitis B surface antigen loss/seroconversion;changes in liver histology.Safety and tolerability were evaluated by the occurrence of adverse events(AEs),serious AEs,laboratory abnormalities,discontinuation of the study drug due to AEs,or death.The primary efficacy and safety analysis set included all patients who were randomly assigned to treatment and received at least one dose of study drug.RESULTS:At week 48,similar proportions of Asians and non-Asians reached HBV DNA400 copies/m L(96%of Asian and 97%of non-Asian patients with HBe Ag-negative CHB and 83%of Asian and 79%of non-Asian patients with HBe Ag-positive CHB had HBV DNA)and normal ALT(78%of Asian and 81%of nonAsian patients with HBe Ag-negative CHB and 71%of Asian and 74%of non-Asian patients with HBe Agpositive CHB had normal ALT).On-treatment HBV DNA decline rates were similar between Asians and nonAsians regardless of baseline HBe Ag status and viralload.HBV DNA decline during the first four weeks was2.9 log10 copies/m L in HBe Ag-negative Asians and nonAsians,and in HBe Ag-positive non-Asians,and 3.1log10 copies/m L in HBe Ag-positive Asians.HBe Ag loss and seroconversion was achieved in 14%of Asians vs 26%and 24%,respectively,in non-Asians.Liver histology improved in 77.2%of Asians and 71.5%of non-Asians.No resistance to TDF developed.No renal safety signals were observed.CONCLUSION:TDF demonstrated similar viral suppression,normalization of ALT,improvements in liver fibrosis,and no detectable resistance in Asian and non-Asian patients regardless of baseline HBe Ag status.     

Maintained virological suppression and renal function with reduced dose tenofovir disoproxil fumarate in renally impaired chronic hepatitis B patients

Tenofovir disoproxil fumarate (TDF) effectively suppresses viral replication in chronic hepatitis B (CHB), but occasionally leads to renal impairment. We evaluated the prevalence of viral and biochemical breakthrough and renal function kinetics in renally impaired patients with CHB on reduced and on full‐dose TDF. This clinic‐based longitudinal cohort study included patients receiving full and reduced dose TDF (due to eGFR [Cockcroft‐Gault] <60 mL/min/1.73 m²). Viral and biochemical breakthroughs were assessed 1 month after starting full and reduced TDF dose until the end‐of‐follow‐up. Breakthroughs were studied in full and reduced dose TDF, and renal function (MDRD) longitudinally before and after dose reduction within patients starting on full‐dose TDF. Of 750 patients on TDF, 78 (10%) had reduced dose and 672 (90%) full dose. At the time of dose reduction, 36 (46%) patients had chronic kidney disease stage G3B. A viral breakthrough occurred in one cirrhotic dialysis‐dependent patient (dosed 300 mg weekly) which resolved without signs of decompensation, and in one patient on full dose which resolved spontaneously. One biochemical breakthrough occurred during dose reduction and resolved naturally without viral breakthrough. The MDRD improved within the first year of dose reduction (+3.0 [2.5] mL/min per year; P < .005) and remained stable thereafter. Fifty‐three (79%) patients reached an MDRD >50 mL/min during dose reduction. Low dose TDF maintains renal function and viral suppression in most renally impaired patients with CHB, even in those with advanced liver disease. This useful, yet simple strategy could be particularly viable in resource‐constrained settings.

Tenofovir is a more suitable treatment than entecavir for chronic hepatitis B patients carrying naturally occurring rtM204I mutations

BACKGROUND Hepatitis B virus(HBV) DNA polymerase mutations usually occur to long term use of nucleos(t)ide analogues(NAs), but they can occur spontaneously in treatment-na?ve chronic hepatitis B(CHB) patients. The naturally occurring HBV DNA polymerase mutations might complicate antiviral therapy with NAs,leading to the generation of drug-resistant viral mutants and disease progression.The most common substitutions are known to be YMDD-motif mutations, but their prevalence and the influence on antiviral therapy is unclear.AIM To investigate prevalence of the naturally occurring rtM204I mutations in treatment-na?ve CHB genotype C2 patients and their influence on antiviral therapy.METHODS A total of 410 treatment-na?ve CHB patients infected with HBV genotype C2 strains were enrolled in this retrospective study. Among the 410 patients, 232 were treated with NAs for at least 12 mo. Significant fibrosis was defined as fibrosis-4 index > 3.25 or aspartate aminotransferase to platelet ratio index > 1.5.Complete viral response(CVR) during NAs was defined as undetectable serum HBV DNA(< 24 IU/m L). The rtM204I variants were analyzed by a newly developed locked nucleotide probe(LNA probe) based real-time PCR(LNA-RTPCR) method.RESULTS The LNA-RT-PCR could discriminate rtM204I mutant-type(17 patients, 4.2%)from rt M204 wild-type(386 patients, 95.8%) in 403 of 410 patients(98.3%sensitivity). Multivariate analysis showed that naturally occurring rtM204I variants were more frequently detected in patients with significant fibrosis [oddratio(OR) 3.397, 95% confidence-interval(CI) 1.119-10.319, P = 0.031]. Of 232 patients receiving NAs, multivariate analysis revealed that achievement of CVR was reversely associated with naturally occurring rtM204I variants prior to NAs treatment(OR 0.014, 95%CI 0.002-0.096, P < 0.001). Almost patients receiving tenofovir achieved CVR at 12 mo of tenofovir, irrespective of pre-existence of naturally occurring rtM204I mutations(CVR rates: patients with rtM204I, 100%;patients without rtM204I, 96.6%), whereas, pre-existence of naturally-occurring rtM204I-mutations prior to NAs significantly affects CVR rates in patients receiving entecavir(at 12 mo: Patients with rtM204I, 16.7%; patients without rtM204I, 95.6%, P < 0.001).CONCLUSION The newly developed LNA-RT-PCR method could detect naturally occurring rtM204I mutations with high-sensitivity. Theses mutations were more frequent in patients with liver fibrosis. Tenofovir is a more suitable treatment than entecavir for CHB patients carrying the naturally occurring rtM204I mutations.     

Relationship between hepatitis B virus DNA levels and liver histology in patients with chronic hepatitis B

AIM： To study the relationship between hepatitis B virus （HBV） DNA levels and liver histology in patients with chronic hepatitis B （CHB） and to determine the prevalence and characteristics of hepatitis B e antigen （HBeAg） negative patients.
METHODS： A total of 213 patients with CHB were studied, and serum HBV DNA levels were measured by the COBAS Amplicor HBV Monitor test. All patients were divided into two groups according to the HBeAg status.The correlation between serum HBV DNA levels and liver damage （liver histology and biochemistry） was explored.
RESULTS： Of the 213 patients with serum HBV DNA levels higher than 10^5 copies/mL, 178 （83.6%） were HBeAg positive, 35 （16.4%） were HBeAg negative. The serum HBV DNA levels were not correlated to the age,history of CHB, histological grade and stage of liver disease in either HBeAg negative or HBeAg positive patients. There was no correlation between serum levels of HBV DNA and alanine aminotransferanse （ALT）,aspartate aminotrans-ferase （AST） in HBeAg positive patients. In HBeAg negative patients, there was no correlation between serum levels of HBV DNA and AST,while serum DNA levels correlated with ALT （r = 0.351, P = 0.042）. The grade （G） of liver disease correlated with ALT and AST （P 〈 0.05, r = 0.205, 0.327 respectively）in HBeAg positive patients. In HBeAg negative patients,correlations were shown between ALT, AST and the G （P 〈 0.01, and r = 0.862, 0.802 respectively）. HBeAg negative patients were older （35 ± 9 years vs 30 ±9 years, P 〈 0.05 ） and had a longer history of HBV infection （8 ± 4 years vs 6 ± 4 years, P 〈 0.05） and a lower HBV DNA level than HBeAg positive patients （8.4± 1.7 Log HBV DNA vs 9.8 ± 1.3 Log HBV DNA, P 〈0.001）. There were no significant differences in sex ratio,ALT and AST levels and liver histology between the two groups.
CONCLUSION： Serum HBV DNA level is not correlated to histological grade or stage of liver disease in CHB patients with HBV DNA mor
