Fibrosis Response Status (ie, Improvement, no Change, or the Worsening of the Fibrosis Score in Participants With Baseline METAVIR Fibrosis Score of F2 or F3).
기간: Baseline to up to Month-36
|
Definitions: Fibrosis scoring: F0 (no fibrosis), F1 (stellate enlargement of portal tract without septa formation, F2 (enlargement of portal tract with rare septa formation, F3 (numerous septa without cirrhosis), F4 (cirrhosis). Improved: Participants whose METAVIR fibrosis score at up to Month-36 decreases by 1 or more units compared to baseline. No Change: Participants whose METAVIR fibrosis score at up to Month-36 is the same as the baseline score. Worsened: Participants whose METAVIR fibrosis score at up to Month-36 increases by 1 or more units compared to baseline. |

Inflammation Response Status (ie, Improvement, no Change, or the Worsening of the METAVIR Activity Score as Compared to Baseline)
기간: Baseline to up to Month-36
|
Activity Scoring: A0 (no histological activity), A1 (minimal activity), A2 (moderate activity), A3 (severe activity), A4 (lobular chronic hepatitis). Changes in liver inflammation defined as follows: Improved: Participants whose METAVIR activity score at up to Month-36 decreases by 1 or more units compared to baseline. No Change: Participants whose METAVIR activity score at up to Month-36 is the same as the baseline score. Worsened: Participants whose METAVIR activity score at up to Month-36 increases by 1 or more units compared to baseline. |
Baseline to up to Month-36
|
|
Mean Change From Baseline to up to Month-36 in the METAVIR Fibrosis Score (Using a Continuous Scale)
기간: Baseline to up to Month-36
|
The change of Metavir Fibrosis Score = Metavir Fibrosis Score at up to Month-36 - Metavir Fibrosis Score at Baseline. Fibrosis scoring: 0 (no fibrosis), 1 (stellate enlargement of portal tract without septa formation, 2 (enlargement of portal tract with rare septa formation, 3 (numerous septa without cirrhosis), 4 (cirrhosis). |
Baseline to up to Month-36

The Number of Participants Whose METAVIR Fibrosis Score Did Not Worsen (ie, the Response Status of Improved/no Change) During Treatment Compared to Baseline
기간: Baseline to up to Month-36
|
Definitions: Fibrosis scoring: F0 (no fibrosis), F1 (stellate enlargement of portal tract without septa formation, F2 (enlargement of portal tract with rare septa formation, F3 (numerous septa without cirrhosis), F4 (cirrhosis). Improved: Participants whose METAVIR fibrosis score at up to Month-36 decreases by 1 or more units compared to baseline. No Change: Participants whose METAVIR fibrosis score at up to Month-36 is the same as the baseline score. Worsened: Participants whose METAVIR fibrosis score at up to Month-36 increases by 1 or more units compared to baseline. |

Mean Change in the METAVIR Activity Score (Using a Continuous Scale)
기간: Baseline to up to Month-36
|
The change of Metavir Activity Score = Metavir Activity Score at up to Month-36 - Metavir Activity Score at Baseline. Activity Scoring: 0 (no histological activity), 1 (minimal activity), 2 (moderate activity), 3 (severe activity), 4 (lobular chronic hepatitis). |
Baseline to up to Month-36

|
Number of Participants With no Worsening (ie, the Response Status of Improved/ no Change) in the METAVIR Activity Score During the Treatment.
기간: Baseline to up to Month-36
|
Definitions: Activity Scoring: A0 (no histological activity), A1 (minimal activity), A2 (moderate activity), A3 (severe activity), A4 (lobular chronic hepatitis). Improved: Participants whose METAVIR activity score at up to Month-36 decreases by 1 or more units compared to baseline. No Change: Participants whose METAVIR activity score at up to Month-36 is the same as the baseline score. Worsened: Participants whose METAVIR activity score at up to Month-36 increases by 1 or more units compared to baseline. |
