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

Participants who were treated in a Gilead-sponsored trial for hepatitis B virus infection.

Description

Key Inclusion Criteria:

  • Must have participated in a Gilead-sponsored chronic hepatitis B (CHB) study no more than 120 days prior to Baseline (Day 1), except for participants from previous Gilead-sponsored study number GS-US-174-0149, who will have up to one year from their last visit in that protocol.
  • Must have the ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
  • Must be willing and able to comply with the visit schedule and study requirements
  • Must have documented HBV DNA < 2,000 IU/mL at time of screening visit, which shall occur no later than 1 year post last study visit in GS-US-174-0149
  • Must have documented hepatitis B surface antigen (HBsAg) negative status anytime during participation in GS-US-174-0149 regardless of ongoing HBV treatment

Key Exclusion Criteria:

  • Patient participating or planning to participate in another clinical study with an investigational agent
  • History of clinically-significant illness or any other major medical disorder that may interfere with follow-up, assessments or compliance with the protocol
  • Believed by the Study Investigator to be inappropriate for study participation for any reason not otherwise listed
  • Received TDF monotherapy either as part of GS-US-174-0149 Arm C (TDF monotherapy arm) or for TDF retreatment, and have taken any HBV antiviral therapy since completion of GS-US-174-0149

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

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 serum hepatitis B surface antigen (HBsAg) decline ≥ 0.5 log10 IU/ml from baseline at Week 48
Time Frame: Week 48
This endpoint will be measured for participants who are HBsAg positive at baseline.
Week 48
Proportion of participants who remain HBsAg negative at Week 48
Time Frame: Week 48
This endpoint will be measured for participants who are HBsAg negative at baseline.
Week 48

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

Week 48
Proportions of participants who remain HBeAg negative and HBeAb positive at Week 144
Time Frame: Week 144
This endpoint will be measured for HBeAg positive who achieved HBeAg seroconversion during the parental study.
Week 144
Proportion of participants with HBV DNA < the lower limit of quantitation (LLOQ) at Weeks 48, 96 and 144
Time Frame: Weeks 48, 96 and 144

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.
December 9, 2014

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.
August 14, 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.
