| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Participants With Combined Response at Week 48 | Week 48 | Combined response was defined as fulfilment of two conditions simultaneously: Undetectable (\< lower limit of quantification (LLOQ, target not detected)) HDV RNA or decrease by ≥ 2 log10 IU/mL from baseline; and ALT normalization. |
| Secondary | Percentage of Participants With Undetectable HDV RNA at Week 48 | Week 48 | Undetectable HDV RNA at Week 48 means undetectable (\< LLOQ, target not detected) HDV RNA at Week 48. |
| Secondary | Percentage of Participants With Alanine Aminotransferase (ALT) Normalization at Week 48 | Week 48 | ALT normalization was defined as an ALT value within the normal range, based on the central laboratories \[Russian sites: ≤ 31 U/L for females and ≤ 41 U/L for males; all other sites: ≤ 34 U/L for females and ≤ 49 U/L for males\]) |
| Secondary | Change From Baseline in Liver Stiffness, as Measured by Elastography at Week 48 | Baseline (Baseline for Delayed Treatment/Bulevirtide 10 mg/day is reset at Week 48), Week 48 | ANCOVA was used for analysis. |

| Secondary | Change From Baseline in Liver Stiffness, as Measured by Elastography at Week 144 | Baseline, Week 144 | MMRM was used for analysis. |
