Study start date: December 1, 2003Actual date on which the first participant was enrolled.

Multicenter, multinational, randomized, double-blind study designed to compare the safety and efficacy of telbivudine (600 mg/day) versus lamivudine (100 mg/day) for 104 weeks in adults with decompensated chronic hepatitis B and evidence of cirrhosis. Patients were pre-stratified by screening Child-Turcotte-Pugh score (CTP score < 9 or ≥ 9) and ALT level (within normal limits (WNL) or > 1.0 x ULN) to help assure similar degrees of hepatic insufficiency and liver inflammation on both treatment arms. After 104 weeks of treatment, participants were followed-up with for an additional 16 weeks.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
232 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation
: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

None (Single-arm trial)
: If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment
: Everyone gets the same treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Factorial assignment
: Participants receive different combinations of treatments.

Sequential assignment
: Participants receive treatments one after another in a specific order, possibly based on individual responses.

Other assignment
: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Participants, researchers, outcome assessors, and care providers do not know which treatment is being given. This is the most complete way to prevent bias and keep the study as neutral as possible.

Other Ways to Mask Information
Open-label
: Everyone knows which treatment is being given.

Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Treatment Groups
Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
Participants received Telbivudine 600 mg and a matching lamivudine placebo orally once a day for up to 104 weeks. Participants were followed-up for 16 weeks post-treatment.

600mg/day oral tablet for 104 weeks

Telbivudine matching placebo or lamivudine matching placebo tablet.
Group II
Active Comparator
Lamivudine 100 mg and a Telbivudine matching placebo orally once a day for up to 104 weeks. Participants were followed-up for 16 weeks post-treatment.

100mg/day oral tablet for 104 weeks

Telbivudine matching placebo or lamivudine matching placebo tablet.
Study Objectives
Primary Objectives

Clinical response defined as achieving all of the following 3 criteria on at least 2 consecutive visits or at the last on-treatment visit: Serum hepatitis B virus (HBV) DNA \< 4 log10 copies/mL, normal Alanine transaminase (ALT) level (ALT ≤ Upper Limit of Normal (ULN)), and improvement (a 2- point or greater reduction in Child-Turcotte-Pugh (CTP) score) or stabilization (not more than a 1-point change in CTP score), compared to the baseline value. CTP scores range from 5-15, higher scores indicate more liver impairment. For Improvement/Stabilization, either of the individual criteria were met.
Secondary Objectives

Time to Clinical Response defined as the number of days elapsed from the baseline visit to achieving initial Clinical Response.

Kaplan-Meier method was used. The duration was calculated as: date of last visit before initial loss of clinical response - date of initial clinical response occurred+1. If a patient did not lose clinical response, it was then censored at the efficacy overall censoring date.

Child-Turcotte-Pugh (CTP) uses 2 clinical variables, ascites and encephalopathy, and 3 laboratory parameters, serum bilirubin, albumin, and prothrombin time. Each variable is assigned a score from 1 to 3, with the combined score comprising the CTP score range of 5 to 15 points. Higher scores indicate more impaired liver function. "Worsening" of CTP score was defined as a 2-point or greater increase from baseline, "improvement" in CTP score was defined as a 2-point or greater reduction from baseline, and "stabilization" of CTP score was defined as a change of 1-point or less from baseline.

Modified CTP was calculated using the 3 biochemical-components (serum bilirubin, albumin, and prothrombin). Total scores range from 3-9; higher scores indicate more liver impairment. Improvement was defined as 2-point or greater reduction in score from baseline. Stabilization comprises a score change of 1-point or less from baseline. Worsening of CTP score was defined as a 2-point or greater increase from baseline. The rationale for assessing changes in this modified (3-component) CTP score is that this maneuver removed the two subjective components of CTP scoring (ascites and encephalopathy).
