A Study to Collect Blood Biomarker Samples From Participants With Chronic Hepatitis B (CHB) Who Received Treatment With Pegasys (Peginterferon Alfa-2a) ± Nucleoside/Nucleotide Analogue

March 8, 2017 updated by: Hoffmann-La Roche

A Phase IV, Blood Sample Collection Study For Exploratory Evaluation of the Association of Single Nucleotide Polymorphisms With Treatment Responses From Subjects With HBe-Antigen Positive or Negative Chronic Hepatitis B, Who Received Therapy for Hepatitis B With Peginterferon Alfa-2a 40kD (Peg-IFN) ± Nucleos(t)Ide Analogue

This Phase 4 study is designed for the collection of blood biomarker samples from participants who have completed CHB treatment with at least 24 weeks of a pegylated interferon alfa-2a (Peg-IFN alfa-2a) containing regimen and at least 24 weeks post-treatment follow-up. Participants may be enrolled from historical studies supported or sponsored by Roche, ongoing studies supported or sponsored by Roche, or from general medical practice. The follow-up of individuals who choose to participate in this study will be in accordance with the ongoing studies or with the general medical practice of the physician. Data from whole blood deoxyribonucleic acid (DNA) samples collected in the GV28555 study or available from previously collected Roche Clinical Repository (RCR) samples will be used for combined analysis with data from other applicable studies. Procedures will include blood sample collection (not applicable for participants who previously have consented and donated RCR DNA samples) and medical record capture.

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.

Measure Description
Time Frame
Single Nucleotide Polymorphisms (SNPs) Associated With HBeAg Seroconversion or Hepatitis B Surface Antigen (HBsAg) Clearance ≥24 Weeks Post-Treatment in HBeAg-Positive East Asian (CN) Population: Additive Model
Time Frame: Single blood sample ≥24 weeks post-treatment
Genome-wide association study (GWAS) approach was used to evaluate the association of SNPs with treatment response. HBeAg seroconversion was defined as the loss of HBeAg and detection of the antibody to HBeAg (anti-HBe). HBsAg clearance was defined as the loss of HBsAg, with or without detection of the antibody to HBsAg (anti-HBs). Associations with treatment response were analyzed using logistic regression and adjusted for covariates. Markers were coded according to additive models of inheritance. Markers surpassing p-value thresholds of p<10^-5 and p<5x10^-8 were considered suggestive and genome-wide significant, respectively. Larger beta coefficients correspond to greater likelihood of treatment response.

GWAS approach was used to evaluate association of SNPs with treatment response. HBeAg seroconversion was defined as the loss of HBeAg and detection of anti-HBe. Undetectable HBV DNA was defined as HBV DNA level below the lower limit of detection (LLD) of 2000 international units per milliliter (IU/mL). HBsAg clearance was defined as the loss of HBsAg, with or without detection of anti-HBs. HBeAg seroconversion and undetectable HBV DNA were a combined criterion in treatment response. Associations with treatment response were analyzed using logistic regression and adjusted for covariates. Markers were coded according to additive models of inheritance. Markers surpassing p-value thresholds of p<10^-5 and p<5x10^-8 were considered suggestive and genome-wide significant, respectively.

Time Frame: Single blood sample ≥24 weeks post-treatment
GWAS approach was used to evaluate the association of SNPs with treatment response. HBeAg seroconversion was defined as the loss of HBeAg and detection of anti-HBe. HBsAg clearance was defined as the loss of HBsAg, with or without detection of anti-HBs. Undetectable HBV DNA was defined as an HBV DNA level below the LLD of 2000 IU/mL. Associations with treatment response were analyzed using logistic regression and adjusted for covariates. Markers were coded according to additive models of inheritance. Markers surpassing p-value thresholds of p<10^-5 and p<5x10^-8 were considered suggestive and genome-wide significant, respectively. Larger beta coefficients correspond to greater likelihood of treatment response.

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.
August 20, 2013

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.

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.
