Prevention of Disease Progress in Chronic Hepatitis C Patients With Liver Fibrosis (Study P02570AM2)(COMPLETED)

7. mars 2017 oppdatert av: Merck Sharp & Dohme LLC

PEG-Intron(TM) Maintenance Therapy vs. an Untreated Control Group for Prevention of Progression of Fibrosis in Adult Subjects With Chronic Hepatitis C With Hepatic Fibrosis (METAVIR Fibrosis Score of F2 or F3), Who Failed Therapy With PEG-Intron Plus REBETOL(R) (in Protocol No. P02370)

The objective of the study is to evaluate the safety and efficacy of PEG-Intron versus no treatment for the prevention of fibrosis progression in adult participants with moderate to severe liver fibrosis secondary to chronic hepatitis C, who failed PEG-Intron plus Rebetol treatment in protocol P02370 (NCT00039871).

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
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).
Tidsramme: 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.

Baseline to up to Month-36

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

Baseline to up to Month-36
Mean Change in the METAVIR Activity Score (Using a Continuous Scale)
Tidsramme: 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.
Tidsramme: 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.
