Trial Outcomes & Findings for Study of Adefovir Dipivoxil for Korean Patients With Chronic Hepatitis B(CHB) Who Have Completed ADF 103814 (NCT NCT00403585)

NCT ID: NCT00403585

Last Updated: 2010-12-15

Results Overview

HBV DNA was tested with Roche Cobas Amplicor HBV monitor test, Lower Limit of Detection 300 copies/mL) after 3 years (156 weeks: Weeks 1-52 in Study ADF103814; Weeks 53-156 in Study 108005) of adefovir therapy). Change from baseline was calculated as the Week 156 value minus the Baseline value. Baseline is defined as the first day of study ADF103814, of which Study 108005 is an extension.

Participant Flow

Study ADF108005 (NCT00403585; 80 subjects enrolled) is an extension of Study ADF103814 (104 subjects enrolled). For several outcome measures, baseline is defined as the first day of Study 103814; thus, baseline data for 104 subjects are provided, even though 80 subjects were enrolled in Study 108005.

PRIMARY outcome

Timeframe: Baseline, Week 156

Population: Study ADF103814 Intent-to-Treat (ITT) Population: All subjects regardless of whether or not the subject completed the planned duration of the study will be analyzed with no data exclusion. As baseline is defined as the first day of study ADF103814, all 104 subjects enrolled in this study were analyzed.

HBV DNA was tested with Roche Cobas Amplicor HBV monitor test, Lower Limit of Detection 300 copies/mL) after 3 years (156 weeks: Weeks 1-52 in Study ADF103814; Weeks 53-156 in Study 108005) of adefovir therapy). Change from baseline was calculated as the Week 156 value minus the Baseline value. Baseline is defined as the first day of study ADF103814, of which Study 108005 is an extension.

SECONDARY outcome

Timeframe: Week 104 and 156

Population: All participants achieving viological response, defined as an HBV DNA level ≤ 300. Some participants were not tested at various weeks.

Hepatitis B e antigen (HBeAg) loss, HBeAg seroconversion (defined as HBeAg negative and hepatitis B e antibody \[HBeAb\] positive), hepatitis B surface antigen (HBsAg) loss and HBsAg seroconversion (defined as HBsAg negative and hepatitis B surface antibody \[HBsAb\] positive). HBeAg and HBsAg seroconversion are defined as the loss (becoming negative) of HBeAg and the concurrent appearance of antibodies against HBeAg and the loss of HBsAg and the concurrent appearance of antibodies against HBsAg, respectively.
