Intervention: Peginterferon alfa-2a
Group B: Combination with Peginterferon alfa-2a + Ribavirin
Participants will receive combination therapy with peginterferon alfa-2a plus ribavirin, administered over 48 weeks.
Intervention: Peginterferon alfa-2a

Intervention: Ribavirin
Outcomes
Primary Outcomes
Number of Participants With Alanine Aminotransferase (ALT) Normalization Plus Negative Hepatitis D Virus (HDV) Ribonucleic Acid (RNA) at 48 Weeks After End of Treatment
Time Frame: Week 96
Normalized ALT was defined as ALT value above the upper limit of normal (ULN) at Baseline with a decrease in ALT value to at/below the ULN at 48 weeks after end of treatment (Week 96). Negative HDV RNA was defined as HDV RNA not detected by polymerase chain reaction (PCR). The number of participants with ALT normalization and negative HDV RNA at Week 96 was reported.
Secondary Outcomes
- Number of Participants With Negative HDV RNA at 48 Weeks After End of Treatment(Week 96)
- Number of Participants With Negative HDV RNA at End of Treatment(Week 48)
- Number of Participants With ALT Normalization Plus Negative HDV RNA at End of Treatment(Week 48)
- Number of Participants With ALT Normalization at 48 Weeks After End of Treatment(Week 96)
- Number of Participants With ALT Normalization at End of Treatment(Week 48)
