Design outcomes

Primary

MeasureTime frame
Main Objective: ? To assess Non-inferiority of monotherapy with TENOFOVIR versus LAMIVUDINE plus ADEFOVIR DIPIVOXIL in lamovudine-resistant chronic hepatitis-B patients in undetectable viral load (DNA-HBV under lower limit of quantification) mainteinance;Secondary Objective: ? To estimate the number of patient (%) with undetectable viral load (DNA-VHB below the lower limit of quantification) at 12, 24 and 36 weeks of treatment ? To assess throughout the 48 weeks of the trial the incidence of resistance-mutations in patients with treatment failure (detection of viral replication). ? To estimate the number of patients (%) with AgHBe and AgHBs loss and seroreversion at 12, 24, 36 and 48 weeks. ? To assess the changes in AgHBs levels at 12, 24, 36 and 48 weeks ? To assess the treatment adherence ? To estimate the incremental cost between therapies ? To collect both clinical and laboratory adverse events;Primary end point(s): ? The percentage of patients with sustained virological response (undetectable HBV-DNA levels or HBV-DNA below the lower limit of quantification) after 48 weeks of treatment.;Timepoint(s) of evaluation of this end point: ? 48 weeks

Secondary

MeasureTime frame
Secondary end point(s): ? The percentage of patients with sustained virological response (undetectable HBV-DNA levels or HBV-DNA below the lower limit of quantification) after 12, 24 and 36 weeks of treatment. ? Proportion of patients with treatment failure (detectable HBV-DNA levels or HBV-DNA level that exceeds the lower limit of quantification) in each treatment group. ? Virological response at 12, 24 and 36 weeks of treatment assessed as percentage of patients with HBeAg or HBsAg loss or seroreversion ? Variations in HBsAg levels after 12, 24, 36 and 48 weeks of treatment. ? Treatment?s adherence assessed with the Morisky-Green scale. ? Drug safety. Number of serious adverse events (clinical or laboratory abnormalities). ? Incremental cost between therapies by means of a cost-minimization analysis;Timepoint(s) of evaluation of this end point: ? after 12, 24 and 36 weeks of treatment. ? after 12, 24, 36 and 48 weeks of treatment. ? after 12, 24 and 36 weeks of treatment. ? after 12, 24, 36 and 48 weeks of treatment. ? after 48 weeks of treatment. ? after 48 weeks of treatment.
