A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) Plus COPEGUS (Ribavirin) in Patients With Chronic Hepatitis C (CHC) Genotype 1 and Human Immunodeficiency Virus-1 (HIV-1) Co-infection - Full Text View

Purpose

This 2-arm study will compare the efficacy and safety of treatment with Pegasys (180 µg weekly) plus Copegus (800 mg daily) and Pegasys (180 µg weekly) plus Copegus (1000-1200 mg daily) in interferon-naive patients with CHC genotype 1 co-infected with HIV-1. Treatment will be administered for 48 weeks, and this will be followed by 24 treatment-free weeks. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Primary Outcome Measures:

Sustained Virological Response (SVR) [ Time Frame: Week 72 ] [ Designated as safety issue: No ]
SVR was defined by the percentage of patients with undetectable Hepatitis C virus (HCV) ribonucleic acid (RNA) at 24 weeks after completion of the 48-week treatment period (i.e., a single last HCV RNA < 20 IU/mL measured ≥ Day 477 [≥ Week 68]). Patients without an HCV measurement at the end of the 24-week untreated follow-up period were considered nonresponders.
Incidence of Adverse Events, Dose Reductions and Withdrawals Due to Anemia [ Time Frame: Up to Week 72 ] [ Designated as safety issue: Yes ]
Adverse events of anemia included hemolytic anemia, aplasia pure red cell, and pancytopenia.

Secondary Outcome Measures:

Virological Response at End of Treatment Period [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
Virological response at the end of the treatment period was defined as a single last HCV RNA measurement <20 IU/mL at the completion of the treatment period (Days 324 to 351). Patients without an HCV measurement at Week 48 were considered nonresponders.
Virological Response at Weeks 4, 12 and 24 [ Time Frame: Weeks 4, 12 and 24 ] [ Designated as safety issue: No ]
Virological response at Weeks 4, 12 and 24 was also defined as a single last undetectable HCV RNA (< 20 IU/mL) falling within the visit windows of Days 16 to 43, 72 to 99, and 156 to 183, respectively. Patients without an HCV measurement at a study week were considered nonresponders at that study week.
Relapse of Virological Response [ Time Frame: Weeks 48 and 72 ] [ Designated as safety issue: No ]
Relapse of virological response was calculated by dividing the number of patients who achieved a virological response at the end of treatment but had detectable HCV RNA at the last assessment posttreatment by the number of patients with a virological response at the end of treatment who had at least one HCV RNA assessment posttreatment.
Rapid Virological Response (RVR) by Week 4 [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
RVR was defined as an undetectable HCV RNA < 20 IU/mL (a single last HCV RNA < 20 IU/mL falling in the time window of Days 2 to 43). Patients without an HCV measurement by Week 4 were considered nonresponders.
Early Virological Response (EVR), Partial EVR and Complete EVR by Week 12 [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
EVR: Undetectable HCV RNA <20 IU/mL or ≥2 log10 drop from pretreatment level, by Week 12 (a single last HCV RNA <20 IU/mL or ≥2 log10 drop from pretreatment level in the time window of Days 2 to 99). Partial EVR: Detectable HCV RNA but ≥2 log10 drop from pretreatment, by Week 12 (a single last HCV RNA detectable but ≥2 log10 drop from pretreatment in the time window of Days 2 to 99). Complete EVR: Undetectable HCV RNA <20 IU/mL, by Week 12 (a single last HCV RNA <20 IU/mL in the time window of Days 2 to 99). Patients without an HCV measurement by Week 12 were considered nonresponders.
