A Study to Evaluate the Efficacy and Safety of Glecaprevir (GLE)/Pibrentasvir (PIB) in Treatment-Naive Adults in Brazil With Chronic Hepatitis C Virus (HCV) Genotype 1 - 6 Infection

A Multicenter, Open-Label Study to Evaluate the Efficacy and Safety of Glecaprevir (GLE)/Pibrentasvir (PIB) in Treatment-Naïve Adults in Brazil With Chronic Hepatitis C Virus (HCV) Genotype 1 - 6 Infection

This was a Phase 3, open-label, multicenter study to evaluate the efficacy and safety of glecaprevir (GLE)/pibrentasvir (PIB) for an 8 or 12-week treatment duration in adults in Brazil with chronic hepatitis C virus (HCV) genotype (GT) 1 to GT6 infection, without cirrhosis or with compensated cirrhosis, who were HCV treatment-naïve.

This was a Phase 3, open-label, multicenter study to evaluate the efficacy and safety of GLE/PIB for an 8- or 12-week treatment duration in adults in Brazil with chronic HCV GT1 to GT6 infection, without cirrhosis or with compensated cirrhosis with a METAVIR System Fibrosis Score of F2 to F3 (without cirrhosis) or F4 (with compensated cirrhosis) or equivalent, who were HCV treatment-naïve.

Inclusion Criteria:

• Participant had positive plasma hepatitis C virus (HCV) antibody and HCV ribonucleic acid (RNA) viral load greater than or equal to 1000 IU/mL at Screening Visit.
• Participant must have been documented as without cirrhosis with METAVIR equivalent fibrosis stage of F2 to F3 or with compensated cirrhosis (F4) based on results of a liver biopsy, or FibroScan, or FibroTest score.
• Participants who were known to be HCV/Human Immunodeficiency Virus (HIV) co-infected may have been enrolled if they had a positive test result for anti-HIV antibody at Screening and were: naïve to treatment with any antiretroviral therapy (ART), or on a stable, qualifying HIV ART regimen for at least 8 weeks prior to Baseline.
• Participants with compensated cirrhosis only: Absence of hepatocellular carcinoma (HCC) within 3 months prior to Screening or a negative ultrasound at Screening.

Exclusion Criteria:

• Current hepatitis B virus (HBV) infection on screening tests.
• Any current or past clinical evidence of Child-Pugh B or C classification (score of > 6) or clinical history of liver decompensation including ascites on physical exam, including hepatic encephalopathy or variceal bleeding.
• Receipt of any investigational or commercially available anti-HCV agents.
