Hepatic decompensation during paritaprevir/ritonavir/ombitasvir/dasabuvir treatment for genotype 1b chronic hepatitis C patients with advanced fibrosis and compensated cirrhosis.

ABSTRACT:

Background and aim

Hepatic decompensation is a severe on-treatment adverse event for chronic hepatitis C treated with paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD). Till now, few papers regarding on-treatment hepatic decompensation have been reported. The study aims to analyze the general feature and predictive factors of on-treatment hepatic decompensation in hepatitis C virus (HCV) genotype 1b-infected patients with advanced fibrosis and compensated cirrhosis who receive treatment with PrOD.

Methods

A real-word cohort enrolled 189 HCV genotype 1b patients with advanced fibrosis and compensated cirrhosis treated with 12-week PrOD. Clinical and laboratory data were analyzed between patients with and without on-treatment hepatic decompensation.

Results

The sustained virologic response rate at 12 weeks after treatment was 97.3% in HCV subtype 1b patients with advanced fibrosis and cirrhosis. On-treatment hyperbilirubinemia (total bilirubin >2 mg/dL) occurred in 27 (14.3%) patients, and the incidence of the increase of total and direct form bilirubin was significantly different during treatment between patients with Child-Turcotte-Pugh score 5 and score 6. Five (18.5%) hyperbilirubinemia patients progressed to hepatic decompensation. Older age (adjusted OR: 1.2, 95% CI: 1.0-1.4) and albumin ?3.6 g/dL (adjusted OR: 10.4, 95% CI: 1.3-81.2) may be two predictors for on-treatment hepatic decompensation by multivariate analysis.

Conclusions

PrOD is an effective direct-acting antiviral agent for antiviral therapy in HCV genotype 1b patients with advanced fibrosis and cirrhosis. Hyperbilirubinemia is possibly the early warning feature of on-treatment hepatic decompensation. This serious adverse event of on-treatment hepatic decompensation is not common. Older age and low baseline albumin level may be predictive factors.

Project description:The combination of ombitasvir (an NS5A inhibitor), paritaprevir (an NS3/4A inhibitor) coadministered with ritonavir (r), and dasabuvir (an NS5B nonnucleoside polymerase inhibitor), referred to as the 3D regimen, and the combination of ombitasvir-paritaprevir-r, referred to as the 2D regimen, have demonstrated high efficacy with and without ribavirin in hepatitis C virus (HCV)-infected subjects. These regimens have potential for coadministration with sofosbuvir (nucleoside NS5B inhibitor) in the treatment of HCV. This phase 1, drug-drug interaction, open-label, multiple-dose study enrolled 32 healthy subjects to receive the 3D or 2D regimen in combination with sofosbuvir. Doses of study drugs were as follows: ombitasvir-paritaprevir-r, 25/150/100 mg daily (QD); dasabuvir, 250 mg twice daily (BID); and sofosbuvir, 400 mg QD. Blood samples were collected on study days 7, 14, and 21 for evaluating drug interaction at steady state. The effect of the 3D and 2D regimens on the pharmacokinetics of sofosbuvir and its circulating metabolite GS-331007 and vice versa was assessed by a repeated-measures analysis. Exposures of the 3D and 2D regimens were similar (?20% change) during coadministration with sofosbuvir and during administration alone. Sofosbuvir exposures were 61% to 112% higher with the 3D regimen and 64% to 93% higher with the 2D regimen than with sofosbuvir alone. GS-331007 total exposures were 27% and 32% higher with the 3D and 2D regimens, respectively, than with sofosbuvir alone. Increases in sofosbuvir and GS-331007 exposures likely resulted from breast cancer resistance protein (BCRP) and/or P glycoprotein (P-gp) transporter inhibition by paritaprevir and ritonavir. No subjects discontinued the study due to study drug-related adverse events. No dose adjustment is recommended for 3D, 2D, or sofosbuvir in clinical trials exploring the safety and efficacy of the combination. (This study has been registered at ClinicalTrials.gov under registration no. NCT02356562 and NCT02292719.).
