Abstract
INTRODUCTION With the introduction of highly effective and safe therapies with next-generation direct-acting antivirals (DAAs), that act without interferon, hepatitis C virus (HCV) infection remains the only treatable chronic infectious disease. AREAS COVERED The review aims to provide an overview of the therapy revolution with a description of specific DAAs, their mechanisms of action, a summary of the safety and efficacy of specific regimens, and a discussion of populations requiring special therapeutic approaches. EXPERT OPINION DAAs are highly effective, safe, and easy to use. However, challenges such as access to health services and loss of patients from the cascade of care, especially in groups disproportionately affected by HCV infection, such as substance abusers, make it difficult to achieve the WHO's goal of HCV elimination. The proposed strategy to combat these difficulties involves a one-step approach to diagnosing and treating the infection, the availability of long-lasting forms of medication, and the development of an effective vaccine. The aforementioned opportunities are all the more important as the world is facing an opioid epidemic that is translating into an increase in HCV prevalence. This phenomenon is of greatest concern in women of childbearing age and in those already pregnant due to treatment limitations.

Safety analysis of glecaprevir/pibrentasvir in patients with markers of advanced liver disease in clinical and real-world cohorts. J Viral Hepat 2022; 29:1050-1061. [PMID: 36036117 PMCID: PMC9827821 DOI: 10.1111/jvh.13738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 04/28/2022] [Accepted: 07/06/2022] [Indexed: 01/18/2023]
Abstract
Chronic hepatitis C virus (HCV) infection has the greatest health impact in patients with advanced liver disease. The direct-acting antiviral (DAA) regimen glecaprevir/pibrentasvir (G/P) is approved for treatment of HCV-infected patients without cirrhosis and with compensated cirrhosis. However, events of liver decompensation/failure have been reported in patients treated with protease-inhibitor-containing DAA regimens, often in patients with advanced liver disease. This study examines the safety of on-label G/P treatment in patients with compensated cirrhosis (F4 at baseline) with markers of advanced liver disease. Patients with cirrhosis were categorized into 4 subgroups, based on different noninvasive markers of advanced liver disease identified using laboratory measures: platelet count < or ≥ 100 × 109 /L, and Child-Pugh score 5 or 6. Separate analyses were performed using pooled data from clinical trials and from real-world post-marketing observational studies. G/P was well tolerated in patients with platelet count ≥100 × 109 /L (n = 800), platelet count <100 × 109 /L (n = 215), a Child-Pugh score of 5 (n = 915) and a Child-Pugh score of 6 (n = 95). In the clinical trial and real-world cohorts two patients and no patients experienced a serious adverse event (AE) possibly related to study drug, respectively; three patients and no patients experienced an AE of special interest for hepatic decompensation and hepatic failure. This analysis reaffirms G/P's safety profile in indicated patients with compensated cirrhosis, including those with markers of more advanced liver disease. Increasing the number of patients treated with short-duration G/P therapy may contribute to meeting HCV elimination targets.

High Sustained Virologic Response Rates of Glecaprevir/Pibrentasvir in Patients With Dosing Interruption or Suboptimal Adherence. Am J Gastroenterol 2021; 116:1896-1904. [PMID: 34465693 PMCID: PMC8389353 DOI: 10.14309/ajg.0000000000001332] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 05/06/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Pangenotypic, all-oral direct-acting antivirals, such as glecaprevir/pibrentasvir (G/P), are recommended for treatment of hepatitis C virus (HCV) infection. Concerns exist about the impact on efficacy in patients with suboptimal adherence, particularly with shorter treatment durations. These post hoc analyses evaluated adherence (based on pill count) in patients prescribed 8- or 12-week G/P, the impact of nonadherence on sustained virologic response at post-treatment week 12 (SVR12), factors associated with nonadherence, and efficacy in patients interrupting G/P treatment. METHODS Data were pooled from 10 phase 3 clinical trials of treatment-naive patients with HCV genotype 1-6 without cirrhosis/with compensated cirrhosis (treatment adherence analysis) and 13 phase 3 clinical trials of all patients with HCV (interruption analysis). RESULTS Among 2,149 patients included, overall mean adherence was 99.4%. Over the treatment duration, adherence decreased (weeks 0-4: 100%; weeks 5-8: 98.3%; and weeks 9-12: 97.1%) and the percentage of patients with ≥80% or ≥90% adherence declined. SVR12 rate in the intention-to-treat (ITT) population was 97.7% (modified ITT SVR12 99.3%) and remained high in nonadherent patients in the modified ITT population (<90%: 94.4%-100%; <80%: 83.3%-100%). Psychiatric disorders were associated with <80% adherence, and shorter treatment duration was associated with ≥80% adherence. Among 2,902 patients in the interruption analysis, 33 (1.1%) had a G/P treatment interruption of ≥1 day, with an SVR12 rate of 93.9% (31/33). No virologic failures occurred. DISCUSSION These findings support the impact of treatment duration on adherence rates and further reinforce the concept of "treatment forgiveness" with direct-acting antivirals.

Abstract
BACKGROUND AND AIMS The revolution of the antiviral treatment of hepatitis C virus (HCV) infection resulting in higher effectiveness came with the introduction of direct-acting antivirals with pangenotypic regimens as a final touch. Among them, the combination of glecaprevir (GLE) and pibrentasvir (PIB) provides the opportunity for shortening therapy to 8 weeks in the majority of patients. Because of still insufficient evaluation of this regimen in the real-world experience, our study aimed to assess the efficacy and safety of 8-week GLE/PIB in chronic hepatitis C patients depending on liver fibrosis and genotype (GT). METHODS The analysis included patients who received GLE/PIB for 8 weeks selected from the EpiTer-2 database, large retrospective national real-world study evaluating antiviral treatment in 12 584 individuals in 22 Polish hepatology centers. RESULTS A total of 1034 patients with female predominance (52%) were enrolled in the analysis. The majority of them were treatment naïve (94%), presented liver fibrosis (F) of F0-F3 (92%), with the most common GT1b, followed by GT3. The overall sustained virologic response after exclusion of nonvirologic failures was achieved in 95.8% and 98%, respectively (P = 0.19). In multivariate logistic regression HCV GT-3 (beta = 0.07, P = 0.02) and HIV infection (beta = -0.14, P < 0.001) were independent predictors of nonresponse. CONCLUSIONS We demonstrated high effectiveness of 8-week GLE/PIB treatment in a non-GT3 population irrespective of liver fibrosis stage. Comparable efficacy was achieved in non-cirrhotic patients regardless of the genotype, including GT3 HCV.

Liver cT 1 decreases following direct-acting antiviral therapy in patients with chronic hepatitis C virus. Abdom Radiol (NY) 2021; 46:1947-1957. [PMID: 33247768 PMCID: PMC8131342 DOI: 10.1007/s00261-020-02860-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 11/04/2020] [Accepted: 11/07/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE Direct-acting antiviral therapies (DAAs) for treatment of chronic hepatitis C virus (HCV) have excellent rates of viral eradication, but their effect on regression of liver fibrosis is unclear. The primary aim was to use magnetic resonance imaging (MRI) and spectroscopy (MRS) to evaluate changes in liver fibrosis, liver fat and liver iron content (LIC) in patients with chronic HCV following treatment with DAAs. METHODS In this prospective study, 15 patients with chronic HCV due to start treatment with DAAs and with transient elastography (TE) > 8 kPa were recruited consecutively. Patients underwent MRI and MRS at baseline (before treatment), and at 24 weeks and 48 weeks after the end of treatment (EoT) for the measurement of liver cT1 (fibroinflammation), liver fat and T2* (LIC). RESULTS All patients achieved a sustained virological response. Liver cT1 showed significant decreases from baseline to 24 weeks post EoT (876 vs 806 ms, p = 0.002, n = 15), baseline to 48 weeks post EoT (876 vs 788 ms, p = 0.0002, n = 13) and 24 weeks post EoT to 48 weeks post EoT (806 vs 788 ms, p = 0.016, n = 13). Between baseline and 48 weeks EoT significant reduction in liver fat (5.17% vs 2.65%, p = 0.027) and an increase in reported LIC (0.913 vs 0.950 mg/g, p = 0.021) was observed. CONCLUSION Liver cT1 decreases in patients with chronic HCV undergoing successful DAA treatment. The relatively fast reduction in cT1 suggests a reduction in inflammation rather than regression of fibrosis.

Adv Ther 2021; 38:1690-1700. [PMID: 33590445 PMCID: PMC7932931 DOI: 10.1007/s12325-021-01647-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 02/02/2021] [Indexed: 11/05/2022]
Abstract
INTRODUCTION One of the remaining barriers to reaching WHO elimination targets of achieving global hepatitis C (HCV) cure is a lack of an established lower limit of detection (LLOD) to confirm cure post-treatment in near-patient technologies. Determining a LLOD at virologic failure aids in increasing testing feasibility through point-of-care assays in resource-limited settings. METHODS We described the level of viremia in 69 patients experiencing virologic failure across 20 clinical trials (ENDURANCE-1, ENDURANCE-2, ENDURANCE-3, ENDURANCE-4, ENDURANCE 5-6, MAGELLAN-1, MAGELLAN-2, EXPEDITION-1, EXPEDITION-2, EXPEDITION-3, EXPEDITION-4, EXPEDITION-5, EXPEDITION-8, SURVEYOR-1, SURVEYOR-2, VOYAGE-1, VOYAGE-2, CERTAIN-1, CERTAIN-2 and APRI). These findings were categorized as on-treatment, post-treatment week (PTW) 4 or PTW12 failures. RESULTS The mean HCV RNA level at baseline in the overall population of 5033 patients was 4,193,712 IU/ml ± 5,955,028 (6.2 log10 IU/ml ± 0.8) compared to 9,585,957 IU/ml ± 8,247,669 (6.8 log10 IU/ml ± 0.5) in 69 patients experiencing virologic failure by PTW12. The mean HCV RNA level at the time of virologic failure for all patients was 6,004,980 IU/ml ± 7,077,728 (6.4 log10 IU/ml ± 0.7). Twenty patients had on-treatment virologic failure with a mean HCV RNA level at the time of failure of 9,136,360 IU/ml ± 8,572,113 (6.7 log10 IU/ml ± 0.7), 36 patients had relapsed by PTW4 with a mean HCV RNA level at the time of relapse of 4,131,344 IU/ml ± 5,246,954 (6.3 log10 IU/ml ± 0.6), and 13 patients, who experienced relapse between PTW4 and PTW12, had a mean HCV RNA at relapse of 6,376,003 IU/ml ± 7,758,968 (6.3 log10 IU/ml ± 1.0). CONCLUSIONS At PTW12, 100% of virologic failures had an HCV RNA > 3.0 log10 IU/ml. The data are encouraging that with a LLOD of 3.0 log10 IU/ml, a point-of-care test could identify all treatment failures accurately; larger studies, including real-world data, are needed to confirm these findings.

Abstract
Hepatitis C virus (HCV) infection is a major cause of end-stage liver disease, including decompensated cirrhosis and hepatocellular carcinoma. Over 95% of patients with HCV infection have achieved sustained virologic response at 12 weeks under the treatment of several pan-genotypic regimens approved for patients with HCV infection. The glecaprevir/pibrentasvir (G/P) regimen has some features that distinguish it from others and is the only 8-week regimen approved for treatment-naive patients and patients experienced in regimens containing (peg)interferon, ribavirin, and/or sofosbuvir, without an HCV NS3/4A protease inhibitor or NS5A inhibitor (except those with genotype 3). This review aims to summarize the efficacy and safety of G/P in HCV-infected patients from clinic trials and real-world studies, including those who have historically been considered difficult to cure.

Abstract
Background and Aims: Glecaprevir/pibrentasvir is a pangenotypic regimen recently approved for the treatment of chronic hepatitis C virus (HCV) infection. The objective of the present review was to summarize the findings from clinical trials to understand how patient-related factors influence glecaprevir/pibrentasvir efficacy (sustained virologic response rates at 12 weeks' after treatment [referred to as SVR12]) and safety. Methods: Data from 21 phase III clinical trials were analyzed. Results: The integrated efficacy analysis included 4,817 patients. Findings showed 97.5% of all included patients with chronic HCV achieved SVR12 in the intention-to-treat population. SVR12 rate was >95% across subgroups of interest. The integrated safety analysis included 4,015 patients. Findings showed that 64.1% of patients reported an adverse event, and <0.1% of patients reported a serious adverse event related to glecaprevir/pibrentasvir. Conclusions: These results indicate that the 8- or 12-week glecaprevir/pibrentasvir treatment is effective for patients infected with HCV genotypes 1-6 without or with compensated cirrhosis, with good safety profiles, irrespective of treatment-experience. Glecaprevir/pibrentasvir is a good option for patients with human immunodeficiency virus/HCV coinfection and comorbid HCV and severe renal impairment.
