Study Description

Brief Summary

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

    1. 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 [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.

    Outcome Measures

    1. Primary Outcome
    Title 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
    Description 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.
    Time Frame Single blood sample ≥24 weeks post-treatment

    Analysis Population Description
    HBeAg-Positive CN Population: All HBeAg-positive participants whose genetic data passed a protocol-specified quality check and shared common East Asian genetic background as compared to haplotype map (HapMap) version 3.0 reference individuals.
    Arm/Group Title HBeAg-Positive CN Participants Treated With Peg-IFN
    Arm/Group Description Adult East Asian participants with HBeAg-positive CHB infection who completed ≥24 weeks of Peg-IFN alfa-2a (alone or in combination with nucleos[t]ide analogues) therapy and ≥24 weeks of post-treatment follow-up were included.

    3. Primary Outcome
    Title SNPs Associated With HBeAg Seroconversion or HBsAg Clearance ≥24 Weeks Post-Treatment in HBeAg-Positive Population: Additive Model
    Description 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. 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.

    Title SNPs Associated With HBeAg Seroconversion Plus Undetectable Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) or HBsAg Clearance ≥24 Weeks Post-Treatment in HBeAg-Positive CN Population: Additive Model
    Description 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.

Markers were coded according to dominant 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.

    21. Primary Outcome
    Title SNPs Associated With HBeAg Seroconversion Plus Undetectable HBV DNA, HBsAg Clearance, or Undetectable HBV DNA ≥24 Weeks Post-Treatment in Non-CN Population: Additive Model
    Description 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. Undetectable HBV DNA was defined as an HBV DNA level below the LLD of 2000 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. Larger beta coefficients correspond to greater likelihood of treatment response.

    Title SNPs Associated With HBsAg Clearance ≥24 Weeks Post-Treatment in CN Population: Dominant Model
    Description GWAS approach was used to evaluate the association of SNPs with treatment response. HBsAg clearance was defined as the loss of HBsAg, with or without detection of anti-HBs. Associations with treatment response were analyzed using logistic regression and adjusted for covariates. Markers were coded according to dominant 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. Only a single SNP (rs7549785) was included in the analysis.
