Trial Outcomes & Findings for Entecavir Plus Adefovir Combination Therapy Versus Entecavir Monotherapy vs Therapy With Adefovir Plus Lamivudine for Chronic Hepatitis B Infected Subjects With Lamivudine-resistant Virus (NCT NCT00410202)

NCT ID: NCT00410202

Last Updated: 2013-11-21

Results Overview

HBV DNA assessments were performed using the Roche COBAS® TaqMan High Pure System (HPS) assay. HBV DNA less than (\<)50 International units per milliliter (IU/mL) = approximately 300 copies/mL. Percentage of participants calculated n/N; n= number of participants with HBV DNA \<50 IU/mL; N = number of participants analyzed.

Participant Flow

A total of 629 participants were enrolled at 60 sites.

Of the 629 participants enrolled, 416 were randomized (195 no longer met study criteria, 9 withdrew consent, and 9 had other reason). One participant randomized to entecavir + adefovir (ADV+LVD) Arm withdrew consent before treatment.

HBV DNA assessments were performed using the Roche COBAS® TaqMan HPS assay. LOQ is the level above which quantitative results may be obtained with a specified degree of confidence. The LOQ is mathematically defined as equal to 10 times the standard deviation of the results for a series of replicates used to determine a justifiable limit of detection. Percentage n/N: n= number of participants with outcome result; N = number of participants analyzed.

HBV DNA assessments were performed using the Roche COBAS® TaqMan HPS assay. LOD is the lowest concentration level that can be determined to be statistically different from a blank (99% confidence). The LOD is typically determined to be in the region where the signal to noise ratio is greater than 5. Limits of detection are matrix-, method-, and analyte-specific.

Participants 'at risk' are those who were treated during Year i and did not develop that resistance or resistance with virologic breakthrough prior to Year i. CP were calculated separately for ETV, ADV and TDF resistance. Participants who discontinue from study drug in Year i were assumed to be in follow up for the entire year. (VBT; a ≥ 1 log10 increase in HBV DNA from the on-treatment nadir, confirmed by 2 sequential HBV DNA results or observed at the last on-treatment HBV DNA).
