Outcome Measures

Primary Outcomes (2)

  • Double-blind: Part 1: Percentage of Participants With HDV Ribonucleic Acid (RNA) >=2 log10 IU/mL Decline From Baseline or HDV RNA Target Not Detected (TND) in Combination With Normal Alanine Aminotransferase (ALT) at Week 48 (Multiple Imputation Approach)

    Percentage of participants with HDV RNA greater than or equal to (\>=) 2 log10 International Units Per Milliliter (IU/mL) decline from baseline or HDV RNA TND in combination with normal ALT at Week 48 using multiple imputation approach was reported. Target not detected (TND) was defined as no traces of HBV RNA were detected/found. Normal ALT was defined as ALT less than (\<) upper limit of normal (ULN) with ULN = 34 units per liter (U/L) for female and 43 U/L for male. The baseline assessment was defined as the last observed non-missing measurement before the date and time of the first administration of any of study intervention on Day 1. The multiple imputation approach was derived using a longitudinal multiple regression model to impute missing data.

    At Week 48

  • Double-blind: Part 2: Percentage of Participants With HDV RNA >=2 log10 IU/mL Decline From Baseline or HDV RNA TND in Combination With ALT at Week 48 (Multiple Imputation Approach)

    Percentage of participants with HDV RNA \>=2 log10 IU/mL decline from baseline or HDV RNA TND in combination with normal ALT at Week 48 using multiple imputation approach was reported. TND was defined as no traces of HBV RNA were detected/found. Normal ALT was defined as ALT \<ULN with ULN = 34 U/L for female and 43 U/L for male. The baseline assessment was defined as the last observed non-missing measurement before the date and time of the first administration of any of study intervention on Day 1. The multiple imputation approach was derived using a longitudinal multiple regression model to impute missing data.

    At Week 48
