Study Endpoints
Primary Endpoints
Percentage of participants with a composite endpoint of virologic response and ALT normalization at Week 24 in brelovitug arms compared to response at Week 12 of delayed-treatment arm
Week 24

The composite endpoint is defined as virologic response (HDV RNA ≥2 log10 IU/mL decrease from Baseline or undetectable HDV RNA (\< the lower limit of quantification \[LLOQ\], target not detected \[TND\]) and ALT normalization (decrease in ALT from baseline to ≤ upper limit of normal \[ULN\])

Percentage of participants with a composite endpoint of virologic response and ALT normalization
Week 48

The composite endpoint is defined as virologic response (undetectable HDV RNA, \< the lower limit of quantification \[LLOQ\], target not detected \[TND\]) and ALT normalization (decrease in ALT from baseline to ≤ upper limit of normal \[ULN\])

Percentage of participants with a composite endpoint
Week 24

Achieving composite endpoint defined as virologic response (undetectable HDV RNA or decline in HDV RNA ≥2 log10 IU/mL) and ALT normalization

Secondary Endpoints
Percentage of participants with treatment-emergent adverse events (TEAEs)
Up to 96 weeks
Percentage of participants who discontinue treatment due to an adverse event (AE)
Up to 96 weeks
Percentage of participants with HDV RNA ≥ 2 log10 IU/mL decline from baseline or TND
Up to 96 Weeks
