Registry Study for Patients With Chronic HBV Receiving Nucleotide Therapy

April 20, 2017 updated by: Gilead Sciences

Observational, Post-marketing Renal Safety Surveillance Registry in Subjects With Chronic Hepatitis B (HBV) Infection With Decompensated Liver Disease Receiving Nucleotide/Side Therapy

This registry will remain open for approximately 5 years (4 years of enrollment + 1 year of follow up). Subjects will be followed until Orthotopic Liver Transplant (OLT), resolution of liver decompensation, death, or conclusion of the registry.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adult participants with chronic HBV infection receiving or anticipated to receive anti-HBV nucleoside/nucleotide therapy and with decompensated liver disease at time of consent.

Description

Key Inclusion Criteria:

  • Estimated glomerular filtration rate (Cockcroft-Gault method)using actual body weight of ≥ 50 mL/min at time of entry into registry
  • Negative serologies for HIV, hepatitis C virus (HCV), and/or hepatitis D virus (HDV)
  • No history of solid organ or bone marrow transplant
  • Currently receiving or anticipated to receive anti-HBV nucleoside/nucleotide therapy within 6 months of inclusion into registry

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Participants with chronic HBV infection
Participants with decompensated liver disease due to chronic HBV infection, who are receiving or anticipated to receive anti-HBV nucleoside/nucleotide therapy, will be included in the study.
Drug: Anti-HBV nucleoside/nucleotide therapy
Subjects with chronic HBV infection and with decompensated liver disease who are receiving or anticipated to receive anti-HBV nucleoside/nucleotide therapy will be identified at centers with liver disease expertise where subjects are monitored on a regular basis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of participants with a confirmed increase in serum creatinine from baseline of at least one grade
Time Frame: Baseline to Year 5
The proportion of participants with a confirmed increase in serum creatinine of at least one grade will be calculated as the number of participants with at least one grade increase in serum creatinine from baseline divided by the total number of subjects enrolled over the 4 years of accrual.
Baseline to Year 5

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of participants with a confirmed increase in serum creatinine from baseline of at least one grade evaluated using the competing risk cumulative incidence framework
Time Frame: Baseline to Year 5
Baseline to Year 5
Proportion of participants with at least one confirmed estimated glomerular filtration rate (eGFR) below 50 mL/min
Time Frame: Baseline to Year 5
Baseline to Year 5
Change in eGFR compared to eGFR at baseline by visit window
Time Frame: Baseline to Year 5
Baseline to Year 5
Proportion of participants who received appropriate dosing relative to renal function
Time Frame: Baseline to Year 5
Baseline to Year 5
Proportion of participants who discontinued anti-hepatitis B virus (HBV) nucleoside/nucleotide therapy due to a renal related event
Time Frame: Baseline to Year 5
Baseline to Year 5
Proportion of participants with at least one change in model for end stage liver disease (MELD) score compared to baseline
Time Frame: Baseline to Year 5
Baseline to Year 5
Change in MELD score and liver disease status compared to MELD score at baseline by visit window
Time Frame: Baseline to Year 5
Baseline to Year 5
Proportion of participants with at least one plasma HBV DNA < 400 copies/mL (69 IU/mL)
Time Frame: Baseline to Year 5
Baseline to Year 5
The median number of renal related adverse events per participant over the evaluation period
Time Frame: Baseline to Year 5
Renal related adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) Preferred Term.
Baseline to Year 5

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 26, 2012

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
April 4, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
