What researchers measure

Primary outcomes

  1. 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).

    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.

    Time frame: Baseline to up to Month-36

Secondary outcomes

  1. Inflammation Response Status (ie, Improvement, no Change, or the Worsening of the METAVIR Activity Score as Compared to Baseline)

    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.

    Time frame: Baseline to up to Month-36

  2. Mean Change From Baseline to up to Month-36 in the METAVIR Fibrosis Score (Using a Continuous Scale)

    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).

    Time frame: Baseline to up to Month-36

  3. The Number of Participants Whose METAVIR Fibrosis Score Did Not Worsen (ie, the Response Status of Improved/no Change) During Treatment Compared to Baseline

    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.

    Time frame: Baseline to up to Month-36

  4. Mean Change in the METAVIR Activity Score (Using a Continuous Scale)

    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).

    Time frame: Baseline to up to Month-36

  5. Number of Participants With no Worsening (ie, the Response Status of Improved/ no Change) in the METAVIR Activity Score During the Treatment.

    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.

    Time frame: Baseline to up to Month-36
