简要总结
This was a Phase 3b, open-label, non-randomized, multicenter study to evaluate the efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1 - 6 infection without liver cirrhosis or with compensated liver cirrhosis and with chronic renal impairment in participants who were either HCV treatment-naïve (TN) or prior treatment-experienced (TE) with interferon (IFN) or pegylated interferon (PegIFN) with or without ribavirin (RBV), or sofosbuvir (SOF) plus RBV with or without pegIFN.
详细描述
The study included a 42-day screening period, a treatment period of either 8, 12, or 16 weeks, and a 24-week post-treatment period. The duration of treatment was determined by product labeling. Participants received glecaprevir/pibrentasvir (GLE/PIB) 300 mg/120 mg once daily. Participants who completed or prematurely discontinued the treatment period were followed for 24 weeks after their last dose of study drug to monitor safety, hepatitis C virus ribonucleic acid (HCV RNA), and the emergence and persistence of viral substitutions.

入选标准
- •Male or female (of non-childbearing potential or using allowed contraceptive methods) at least 18 years of age time of Screening
- •Participant had a positive anti-hepatitis C virus (HCV) antibody (Ab) and plasma HCV ribonucleic acid (RNA) greater than or equal to 1000 IU/mL at the Screening Visit.
- •Participant had an estimated glomerular filtration rate (eGFR) less than 45 mL/min/1.73 m^2 as estimated by the Modification of Diet in Renal Disease (MDRD) method at Screening according to the following formula: eGFR (mL/min/1.73 m^2 ) = 175 × (Serum Creatinine) ^-1.154 × Age^-0.203 × (0.742 if female) × (1.212 if black), or were dialysis dependent. Subjects requiring dialysis had to have been receiving dialysis for at least 1 month prior to enrollment, and may have been on hemodialysis or peritoneal dialysis.
- •Cirrhotic participants only: absence of hepatocellular carcinoma (HCC) as indicated by a negative ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI) within 3 months prior to Screening or a negative ultrasound at Screening. Participants who had an ultrasound with results suspicious of HCC followed by a subsequent negative CT or MRI of the liver were eligible for the study.
排除标准
- •Female participants who were pregnant, breastfeeding, or were considering becoming pregnant during the study or for approximately 30 days after the last dose of study drug
- •Current hepatitis B virus (HBV) or human immunodeficiency virus (HIV) infection on screening tests, defined as:
- •Positive test result at Screening for hepatitis B surface antigen (HBsAg), or;
- •HBV deoxyribonucleic acid (DNA) greater than lower limit of quantification (LLOQ) in participants with isolated positive hepatitis B core antibody (HBcAb), (i.e., negative HBsAg and Anti-HBsAg), or;
- •Positive anti-HIV antibody (Ab).
- •Any current or historical clinical evidence of decompensated cirrhosis, including any current or past evidence of Child-Pugh B or C classification, hepatic encephalopathy or variceal bleeding; radiographic evidence of small ascites; or prior or current empiric use of lactulose/rifaximin for neurologic indications. Prophylactic use of beta blockers was not exclusionary.
- •Clinical history of acute renal failure in the 3 months prior to Screening
- •History of severe, life-threatening, or other significant sensitivity to any excipients of the study drugs
- •Clinically significant abnormalities or co-morbidities, or recent (within 6 months prior to study drug administration) alcohol or drug abuse that could preclude adherence to the protocol in the opinion of the investigator
- •Receipt of any investigational or commercially available direct acting anti-HCV agents other than sofosbuvir
