Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with HDV RNA below LLOQ with TND or a decrease of ≥ 2 log10 from baseline, and ALT normalization at Week 48 of the treatment period | Week 48 | Proportion of participants with HDV RNA below Lower Limit of Quantification (LLOQ) with target not detected (TND) or a decrease of ≥ 2 log10 from baseline, and ALT normalization at Week 48 of the treatment period |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ctrough,ss | up to week 96 | Steady-state trough concentration of libevitug |
| Proportion of participants with HDV RNA below LLOQ or a decrease of ≥ 2 log10 from baseline, and ALT normalization | up to week 96 | — |
| Proportion of participants with HDV RNA below LLOQ or a decrease of ≥ 2 log10 from baseline | up to week 96 | — |
| Proportion of participants with plasma HDV RNA achieving HDV RNA < LLOQ | up to week 96 | — |
| Proportion of participants with ALT normalization | up to week 96 | — |
| Change from baseline in liver stiffness measurement (LSM) | up to week 96 | — |
| Change from baseline in plasma HDV RNA levels at different time points | up to week 96 | — |
| Change from baseline in Model for End-Stage Liver Disease (MELD) score at different time points | up to week 96 | — |
| Change from baseline in Child-Pugh score at different time points during the treatment period, extended treatment period and follow-up period. (A higher Child-Pugh score indicates poorer liver function, more severe disease, and a worse prognosis) | up to week 96 | — |
| Percentage of participants with treatment-emergent adverse events (TEAEs) | up to week 120 | — |
| Liver related clinical events | up to week 120 | — |
