Retreatment of patients with treatment failure of direct-acting antivirals: Focus on hepatitis C virus genotype 1b
The recent development of direct-acting antiviral agents (DAAs) against hepatitis C virus (HCV) infection could lead to higher sustained virological response (SVR) rates, with shorter treatment durations and fewer adverse events compared with regimens that include interferon. However, a relatively small proportion of patients cannot achieve SVR in the first treatment, including DAAs with or without peginterferon and/or ribavirin. Although retreatment with a combination of DAAs should be conducted for these patients, it is more difficult to achieve SVR when retreating these patients because of resistance-associated substitutions (RASs) or treatment-emergent substitutions.......

The changing HCV treatment cascade
Although the IDSA/AASLD guidelines provide the map to managing HCV, they do not identify the ideal interferon-free regimen to begin with, nor have they given a clear path to treating genotype 3 and those with decompensated cirrhosis. This ever-changing field will require collaboration among health care providers, including those specializing in infectious diseases, hepatology and gastroenterology, as well as pharmacists, to optimize treatment strategies. As the landscape of HCV continues to update with new literature and new medications, this subspecialty continues to be dynamic.

JacobsonFor patient populations that we have been accustomed to treating with high levels of efficacy and tolerability, we now have new features like shorter duration of therapy. For those who previously failed direct- acting antiviral therapy who previously had no treatment, we now have an approved regimen.

Genotype 3
The fixed-dose combination of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) (Technivie, AbbVie), which is approved to treat HCV genotype 4, was combined with the pangenotypic DAA, sofosbuvir (SOF) (Sovaldi, Gilead), in addition to ribavirin for 12 weeks in patients having genotype 3 with cirrhosis, and with or without ribavirin in type 3 patients without cirrhosis. In addition, the regimen with ribavirin was administered for either 6 or 8 weeks to genotype 2 patients without cirrhosis. If the regimen without ribavirin proves efficacious, Shafran explained, it would offer a treatment option for many patients unable to tolerate it.

September 8, 2017
In summary, our study found that successful treatment of chronic HCV with DAA therapy is associated with improvement in liver stiffness, assessed by VCTE measured serially over the first 12 months after treatment. Continued improvement in VCTE scores between EOT and12 months post-treatment suggests possible early regression of fibrosis in addition to resolution of inflammation that occurs soon after starting HCV therapy. Longer-term data are needed to determine whether improvement in liver stiffness continues beyond 1 year, and larger studies are needed to elucidate factors associated with rapidity and magnitude of improvement.

In patients with advanced fibrosis, pretreatment LS significantly reduced during DAA therapy. SVR was the only independent factor associated with the regression in LSM. However, irrespective of achieving SVR, liver damage still persisted in a substantial proportion of patients. Thus, early treatment of HCV-infected patients can significantly prevent residual liver damage.

Towards supporting greater and lower cost access to direct acting antiviral treatment for hepatitis C for all patients
At the Sultan Qaboos University Hospital, using the EASL 2016 guidelines,[8] we have treated 58 HCV patients [28% genotype 3, 26% cirrhotic with 40% of them decompensated, and 3% severe chronic kidney disease (CKD)] with generic DAAs including (sofosbuvir, ledipasvir, and daclatasvir). Sustained virological response was achieved in 57 patients (98%), the remaining one patient with severe CKD discontinued treatment due to worsening renal function. All patients with decompensated cirrhosis were delisted from transplantation.

In chronic HCV infection, oral DAAs have high sustained virologic response
In patients with chronic hepatitis C virus (HCV) infection, what are the efficacy and safety of oral direct-acting antiviral (DAA) regimens?
Main results - The main results for HCV genotype 1 and 3 are in the Table;

SVR varied according to treatment experience, cirrhosis status, and addition of ribavirin. SVR rates for genotypes 2, 4, 5, and 6 were > 90%. Rates of serious adverse events were < 10%.

Voxilaprevir, a second-generation HCV protease inhibitor, in combination with the already approved combination of sofosbuvir and velpatasvir, was evaluated in the POLARIS trials and found to be a safe and effective regimen. Patients with prior DAA treatment failure, genotype 3, cirrhosis and/or unfavorable resistance profiles all achieved cure rates of 96% or greater. The most distinctive role for this potent regimen may prove to be as a salvage regimen for patients who have failed previous DAA therapy

Version of Record online: 29 JUN 2017 | DOI: 10.1002/cld.635
Three new antiviral therapies for viral hepatitis C are anticipated in the next several months: GP, glecaprevir (protease inhibitor [PI])/pibrentasvir (NS5A inhibitor); SOF/VEL/VOX, sofosbuvir (NS5B inhibitor)/velpatasvir (NS5A)/voxilaprevir (NS3); and MK3, grazoprevir (NS3) + MK-3682 (NS5B) + NS5A inhibitor (elbasvir or Ruzasvir).  Each is a pangenotypic all-oral fixed dose combination (FDC) with high potency and efficacy against common NS3 and NS5A polymorphisms. Multiple safety and efficacy abstracts were presented at the 67th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in November 2016. In this article, I will address why we need new therapies as well as what is still unaddressed in the arsenal against hepatitis C.

Response Tailored Protocol Versus the Fixed 12 Weeks of Dual Sofosbuvir/Daclatasvir Treatment in Egyptian Patients With Chronic Hepatitis C Genotype-4 Infection
The decision of shortening the duration of therapy of non-cirrhotic chronic hepatitis C genotype-4 patients with dual sofosbuvir plus daclatasvir to 8 weeks instead of the recommended 12 weeks, if based on achieving viral negativity in serum at week 2 as an on-treatment qualifier, could provide a prudent basis to avoid unnecessary long treatment courses. This could not only reduce the drug exposure and the risk of adverse drug reactions, but also cut the cost of full treatment course with such expensive medications by one third.

The Changing HCV Landscape: Pangenotypic Regimens
DAAs for HCV infection have all but replaced IFN as the foundation of treatment for HCV across all genotypes. Among the major advantages of these oral regimens, beyond their remarkable efficacy, has been their relatively clean safety profile. Adverse effects are common but generally mild, including headache, fatigue, and insomnia—and are trivial relative to the effects of earlier regimens, reflected by a low rate of discontinuation for adverse events. Clinicians must be aware of potential drug–drug interactions, and should prescribe these medications with a commitment toward mastering these and/or consulting the numerous published and online references, including package inserts, containing this information.

Multiple abstracts for HCV therapies were also presented as AbbVie, Merck & Co, and Johnson & Johnson attempted to demonstrate differentiation in a highly-competitive market with few unmet needs remaining. AbbVie presented data from multiple Phase III studies which highlighted glecaprevir/pibrentasvir’s pan-genotypic efficacy in non-cirrhotic genotype 3 (GT-3) patients (ENDURANCE-3) and cirrhotic GT-1/2/4/5/6 patients (EXPEDITION-1), as well as its maintenance of competitive cure rates in direct-acting antiviral-experienced GT-1/4 patients (MAGELLAN-1) and posttransplant patients (MAGELLAN-2). Merck & Co presented data from the Phase II C-SURGE study in DAAexperienced patients which demonstrated that its triple combination of uprifosbuvir/grazoprevir/ruzasvir was an effective salvage regimen in DAA-experienced patients with resistance-associated substitutions, and future studies will investigate the regimen in both DAA-naïve and DAA-experienced patients. Finally, Johnson & Johnson suffered a setback as its triple combination of AL-335/odalasvir/simeprevir failed to demonstrate competitive efficacy in GT-3 patients, prompting the company to discontinue development for this subgroup and putting an end to the company’s hopes of marketing a pan-genotypic regimen. While AL-335/odalasvir/simeprevir is still being developed for the remaining GTs and could shorten treatment duration to just six weeks in non-cirrhotic GT-1 patients, it is likely that Johnson & Johnson will be forced to offer significant discounts to compensate for its late entry to the market.

Glecaprevir/pibrentasvir 95% SVR12 in HCV Geno 3 treatment naïve, non-cirrhotic patients
Study results presented today demonstrate that the oral, once-daily treatment regimen of glecaprevir/pibrentasvir (G/P) resulted in 95% sustained virologic response rates at 12 weeks post treatment (SVR12) in patients with Hepatitis C virus (HCV) genotype 3. In the ENDURANCE-3 study, presented at The International Liver Congress™ 2017 in Amsterdam, The Netherlands, patients infected with HCV genotype 3 without cirrhosis and who had no previous treatment history were treated with the new regimen for eight or 12 weeks, which was well tolerated. G/P had a similar safety profile to the commonly used combination of sofosbuvir and daclatasvir for 12 weeks, to which G/P was actively compared in the study.

Summary - NEJM Journal Watch
Researchers examined 42 randomized trials of oral hepatitis C treatments that included at least two direct-acting antivirals. Among the findings:
  • For genotype 1 infection, the most common HCV type, sustained virologic response rates were above 95% for six regimens.
  • For patients with HCV genotype 3 and without cirrhosis, sofosbuvir plus velpatasvir or daclatasvir for 12 weeks seemed to be most effective.
  • For genotype 3 with cirrhosis, velpatasvir-sofosbuvir had higher response rates. That drug combination was also highly effective (99% response rate) for genotypes 2, 4, 5, and 6.
  • Patient groups traditionally considered difficult to treat — including those with HIV, severe kidney disease, or liver transplant — had high response rates and limited adverse events.

Decreasing racial disparity with the combination of ledipasvir–sofosbuvir for the treatment of chronic hepatitis C
African Americans (AA) in the US are twice as likely to be infected with hepatitis C virus (HCV) compared to the non-Hispanic-white US population (Cau). They are also more likely to be infected with HCV genotype 1, more likely to develop hepatocellular carcinoma, and, in addition, have a lower response rate to interferon-based therapies. With the increase in response rates reported for combinations of direct-acting antivirals, the possibility that racial disparity would be eliminated by agents that directly inhibit virus replication has become a reality. The objective of this review is to evaluate the literature from clinical studies and retrospective analysis with respect to the response of AA to the most prescribed antiviral combination sofosbuvir plus ledipasvir. While few studies have focused on AA patients, sufficient information is availed from the literature and studies in our predominately AA clinic population to confirm that ledipasvir–sofosbuvir has a similar effectiveness in AA as compared to Cau.

Hepatitis C-related hepatocellular carcinoma in the era of new generation antivirals
Hepatitis C virus infection is a major cause of hepatocellular carcinoma worldwide. Interferon has been the major antiviral treatment, yielding viral clearance in approximately half of patients. New direct-acting antivirals substantially improved the cure rate to above 90%. However, access to therapies remains limited due to the high costs and under-diagnosis of infection in specific subpopulations, e.g., baby boomers, inmates, and injection drug users, and therefore, hepatocellular carcinoma incidence is predicted to increase in the next decades even in high-resource countries.

Moreover, cancer risk persists even after 10 years of viral cure, and thus a clinical strategy for its monitoring is urgently needed. Several risk-predictive host factors, e.g., advanced liver fibrosis, older age, accompanying metabolic diseases such as diabetes, persisting hepatic inflammation, and elevated alpha-fetoprotein, as well as viral factors, e.g., core protein variants and genotype 3, have been reported. Indeed, a molecular signature in the liver has been associated with cancer risk even after viral cure. Direct-acting antivirals may affect cancer development and recurrence, which needs to be determined in further investigation.

Manuscript Title: Augmentation of HCV specific immunity and Sustained virological response (SVR)
Combination therapy of SOF combined with ledipasvir (LDV, an NS5A inhibitor) for 12weeks demonstrated high SVR rates (95% to 99%) in treatment-naive patients with HCV GT-1 infection (14). We have demonstrated that 14 HCV GT-1 patients who had virologic relapse after treatment with SOF plus RBV for 24 weeks in the SPARE study were able to be successfully re-treated with SOF plus LDV for 12 weeks (15). Therefore, in the present study, we hypothesize that the retreatment of these relapsers with SOF plus LDV lead to a potent suppression of HCV replication, reversal of T cell exhaustion, and augmentation of HCV-specific protective immunity with viral clearance. We aimed to evaluate the HCV-specific immune responses in these patients and specifically investigated the phenotypic and functional changes in peripheral blood T cells pre- and post-treatment to identify immune responses associated with viral clearance

Rarer HCV Types Still Need Attention
Genotype 1 HCV infection accounts for 75% of all HCV infection globally and was traditionally difficult to treat in the era of interferon. For these reasons, new direct-acting agents (DAAs) have mostly targeted genotype 1 infection. With the high cure rates afforded for genotype 1 HCV infection, we are now focusing attention on other genotypes. In particular, genotype 3 infection remains more challenging to treat as there may be baseline resistance to NS5A inhibitors, a type of DAA. Recently the first pan-genotypic agent effective against HCV genotypes 1-6 was approved. As more pan-genotypic agents become available, the specific HCV genotype may factor less into the treatment recommendations. For HCV genotypes that are more rare, such as genotypes 5 or 6, the experience with DAAs has been limited and more data are needed.

Its effectiveness in genotype 2 HCV-infected patients is unknown, since reduced in vitro activity of LDV against genotype 2 HCV has hindered large-scale studies in this population (about 13% of HCV-infected patients globally).

In this phase II, manufacturer-sponsored, open-label study, investigators evaluated the efficacy of LDV/SOF in genotype 2 HCV-infected patients at two centers in New Zealand. An initial cohort was to receive daily LDV/SOF for 12 weeks, and if at least 90% achieved a sustained viral response (SVR; HCV RNA <15 IU/mL) at 4 weeks after therapy, a second cohort was enrolled to receive 8 weeks of daily LDV/SOF. The primary endpoint for both cohorts was an SVR 12 weeks after therapy (SVR12).

The study cohort included a total of 53 patients (77% HCV treatment naive), of whom 26 received 12 weeks of therapy. Only two participants had cirrhosis. All patients receiving 12 weeks of therapy achieved SVR12 except for one patient who received only one dose of drug before withdrawing consent. Among patients receiving 8 weeks of therapy, the SVR12 rate was only 74%. The most common adverse events were headache and fatigue, and none led to drug discontinuation.

This small phase II study demonstrates high efficacy of a 12-week course of LDV/SOF for the treatment of genotype 2 HCV-infected patients. Eight weeks of therapy appears to be inadequate, and it is unclear if 12 weeks will produce similar SVR rates among cirrhotic patients. If these results are replicated in phase III trials and the drug is determined to be effective in patients with cirrhosis as well, one of the most widely used and safe regimens for the treatment of HCV infection could be available to a large new population.

Sovaldi-based regimens lead to high SVR rates in Egypt
Patients with hepatitis C virus infection in Egypt achieved rates of sustained virologic response at week 12 with Sovaldi-based regimens that were comparable to those demonstrated in phase 3 clinical trials, according to real-world study data.

HCV is one of the most significant health problems in Egypt, and accordingly, the country’s Ministry of Health National Treatment Programme “ensured that [Sovaldi; sofosbuvir, Gilead Sciences] became available in 2014 at prices appropriate for the scale of the epidemic of HCV and for the economic situation in Egypt,” investigators wrote. “Our aim was to assess the clinical effectiveness of the [sofosbuvir]-based treatment regimens,” — both dual and triple therapies — “and to demonstrate the predictors of response in our chronic HCV genotype 3 Egyptian patients.”

Key points
-Current real-world experience supports the use of either LDV/SOF±RBV or OBV/PTV/r±DSV±RBV in genotype 1 and 4 infected patients whatever the severity of fibrosis.
-HCV treatment history, HIV coinfection and previous liver or kidney transplantation do not influence the efficacy and safety of these two regimens.
-The efficacy of the SOF+SMV±RBV regimen was relatively low in real-world results.
-There is still not enough real-world data in patients infected with genotype 3 and other genotypes.

All-Oral DAA Therapy in HCV-Advanced Liver Disease
In summary, all-oral, sofosbuvir-based HCV therapy in GT1 or GT2 patients with advanced liver disease presents a good option. Real-life data on SVR are encouraging and helps in improvement in severity of liver disease in most patients. It is unclear, based on short follow-up period, what the long-term benefits might be, and what baseline and on-treatment predictors might address potential benefit vs. harm. Long-term follow-up is needed to more convincingly address the benefits of eradicating HCV infection in those with advanced liver disease. While ledipasvir, an NS5A inhibitor and sofosbuvir combination has been the treatment of choice in GT1 patients, this combination is unfortunately not available in several countries. Ledipasvir and sofosbuvir have worked effectively in patients with decompensated liver disease.[16,26] However, in some countries such as Brazil with a large hepatitis C population, sofosbuvir and simeprevir are available while ledipasvir is not and thus sofosbuvir and simeprevir combination serves as an effective therapeutic option. Furthermore, with the wide spread use of the NS5A and sofosbuvir combination, there has been the emergence of NS5A resistance, thus making the protease inhibitor, simeprevir and sofosbuvir a viable rescue strategy. Also these data are relevant to regions of the World, where generic sofosbuvir is available and potentially simeprevir can be used in combination with success

In conclusion, in this small study in treatment-naïve and treatment-experienced patients with chronic HCV genotype-1b infection and mild or moderate hepatic impairment, the response to 24 weeks of treatment with faldaprevir, deleobuvir and ribavirin was not durable, with 74% of patients achieving SVR4 but only 57% achieving SVR12. Since this study was initiated, the HCV field has changed rapidly with the advent of new DAAs and all-oral DAA combinations. Because of this and based on the results of the phase 3 HCVerso1 and HCVerso2 trials [16], the development of the faldaprevir–deleobuvir combination has been terminated.
