POLARIS-2: Voxilaprevir safe, effective with Epclusa in multiple HCV genotypes
BOSTON — A novel pangenotypic protease inhibitor, voxilaprevir, yielded encouraging outcomes when administered with Epclusa, regardless of HCV genotype or cirrhosis status, but remained non-inferior to the combination direct-acting antiviral, according to findings presented at The Liver Meeting 2016.
“Sof/vel/vox for 8 weeks resulted in a 95% SVR rate in DAA-naïve genotype 1 to 6 patients with or without cirrhosis,” Ira M. Jacobson, MD, chair of the department of medicine at Mount Sinai Beth Israel Medical Center and co-Chief Medical Editor for HCV Next, said during his presentation. “The regimen did not meet noninferiority as compared to the 98% SVR12 rate with sof/vel for 12 weeks and the difference between the regimens was largely attributed to more relapses amongst patients with genotype 1a infection in the sof/vel/vox group.”.......

Commentary Is stronger better in curing hepatitis C virus infection?
Thanks to a better understanding of the hepatitis C virus (HCV) life-cycle, HCV direct-acting antiviral agents (DAAs) targeting the viral proteins implicated in the virus replication have been developed: they inhibit specifically the NS3/4A protease, the NS5B polymerase and the multifunctional NS5A replication complex (1). DAAs have revolutionized the treatment of HCV infection over the last 5 years. Oral interferon-free combinations of at least two DAAs showed high antiviral efficacy, easy dosing, fair tolerance, and manageable drug-drug interactions, whatever the combination for treatment duration of 8, 12 or 24 weeks according to the patients profile.

BACKGROUND & AIMS:
Few studies have examined factors associated with disease progression in hepatitis C virus (HCV) infection. We examined the association of 11 risk factors with adverse outcomes in a population-based prospective cohort observational study of Alaska Native/American Indian persons with chronic HCV infection.
METHODS:
We collected data from a population-based cohort study of liver-related adverse outcomes of infection in American Indian/Alaska Native persons with chronic HCV living in Alaska, recruited from 1995 through 2012. We calculated adjusted hazard ratios (aHR) and 95% CIs for end-stage liver disease (ESLD; presence of ascites, esophageal varices, hepatic encephalopathy, or coagulopathy), hepatocellular carcinoma (HCC), and liver-related death using a Cox proportional hazards model.
RESULTS:
We enrolled 1080 participants followed for 11,171 person-years (mean, 10.3 years); 66%, 19%, and 14% were infected with HCV genotypes 1, 2, and 3, respectively. On multivariate analysis, persons infected with HCV genotype 3 had a significantly increased risk of developing all 3 adverse outcomes. Their aHR for ESLD was 2.1 (95% CI, 1.5-3.0), aHR for HCC was 3.1 (95% CI, 1.4-6.6), and aHR for liver-related death was 2.4 (95% CI, 1.5-4.0) compared to genotype 1. Heavy alcohol use was an age-adjusted risk factor for ESLD (aHR, 2.2; 95% CI, 1.6-3.2), and liver-related death (aHR: 2.9; 95% CI, 1.8-4.6). Obesity was a risk factor for ESLD (aHR, 1.4; 95% CI, 1.0-1.9, and diabetes was a risk factor for ESLD (aHR, 1.5; 95% CI, 1.1-2.2). Male sex was a risk factor for HCC (aHR, 3.6; 95% CI, 1.6-8.2).
CONCLUSIONS:
In a population-based cohort study of American Indian/Alaska Native persons with chronic HCV infection, we found those infected with HCV genotype 3 to be at high risk for ESLD, HCC, and liver-related death.

Full Text ArticleSafety, Tolerability, and Efficacy of Sofosbuvir Plus Ribavirin in Elderly Patients Infected with Hepatitis C Virus Genotype 2
AbstractBackground: An interferon-free regimen including sofosbuvir and ribavirin (RBV) for patients with hepatitis C virus (HCV) genotype 2 (G2) infection leads to a drastic improvement of sustained virological response (SVR). However, the safety, tolerability, and efficacy in patients aged 75 or older have not been completely understood.Summary: Fifty-six patients with HCV G2 infection who were treated with sofosbuvir and weight-based dose of RBV were enrolled. Thirty-seven patients aged ≥75 and 19 patients aged ≤74 were classified as the aged and non-aged groups, respectively. The aged group was characterized by significantly more number of women, history of hepatocellular carcinoma, low serum albumin (ALB) level, low hemoglobin (Hb) concentration, low estimated glomerular filtration rate (eGFR), and high fibrosis-4 index (p = 0.0029). Forty-one patients were evaluated for SVR at 12 weeks after the end of therapy (SVR12); of them, all but one completed the treatment scheduled for 12 weeks. The aged group showed lower SVR12 rate than the non-aged group (81.3% for aged and 96.0% for non-aged groups). Although the Hb concentration and eGFR are significantly lower in the aged group throughout the clinical course, all patients in the aged group completed the 12-week treatment with a gradual increase of serum ALB level.Key Messages: The combination of sofosbuvir plus RBV is tolerable and beneficial in patients aged >75. However, intensive management of anemia by dose reduction of RBV is necessary, which could lead to a low SVR12 rate compared to that observed in patients younger than 75 years.

Effectiveness of Elbasvir and Grazoprevir, With or Without Ribavirin, Treatment-Experienced Patients with Chronic Hepatitis C Infection
The combination tablet of elbasvir and grazoprevir, with or without ribavirin, was highly efficacious in inducing an SVR12 in patients with HCV genotype 1, 4, or 6 infection failed by previous treatment with peg-interferon and ribavirin, including patients with cirrhosis and/or a prior null response
Zepatier less costly, more effective than Harvoni, Epclusa for Hepatitis C
According to recent research presented at AMCP Nexus 2016, hepatitis C genotype 1 treatment with Zepatier (elbasvir/grazoprevir; Merck) was more effective and less expensive when compared to Harvoni (ledipasvir/sofosbuvir; Gilead) and Epclusa (sofosbuvir/velpatasvir; Gilead).
New hepatitis C product covers all six genotypes
When asked about the current HCV market and evidence-based treatment recommendations to manage this disease, C. Wayne Weart, PharmD, BCPS, FASHP, FAPhA, a professor of clinical pharmacy and outcome sciences at South Carolina College of Pharmacy, told Pharmacy Today that, based upon the updated guidelines from July 2016 and the new FDA-approved hepatitis C once-a-day, single-pill medications, “I am suggesting that the following agents replace ledipasvir and sofosbuvir (Harvoni—Gilead), which costs approximately $95,000 for 12 weeks of therapy and even more if you need 24 weeks of therapy. The most cost-effective therapy for patients who are candidates for and can take it would be Merck’s elbasvir and grazoprevir tablets (Zepatier).” According to Weart, the cost is approximately $55,000 for 12 weeks of therapy.Weart recommended that treatment-naive patients with no cirrhosis and genotype 1a infection undergo testing for virus with NS5A resistance–associated variant polymorphisms (RAVs) to determine the best therapy. If no baseline NS5A RAVs are present, monotherapy for 12 weeks with elbasvir and grazoprevir should be given, but if baseline NS5A RAVs are present, ribavirin should be added to 16 weeks of treatment with elbasvir and grazoprevir. Patients with genotype 1b or 4 should receive elbasvir and grazoprevir once daily for 12 weeks.
“For those with genotypes 2, 3, 5, and 6, I would recommend this new therapy, sofosbuvir and velpatasvir, to be given for 12 weeks, which comes in at an approximate cost of $75,000,” said Weart.

Hepatitis C drugs now effective for most genotypes
There are two or three options for the treatment of genotypes one and four. Currently, one treatment is preferred for genotype 3 (sofosbuvir and daclatasvir are used — with or without ribavirin depending on whether the patient has cirrhosis). Newer agents held out the prospect of further options, said Dr Feeney.

Review article on management of hepatitis C genotype 4 in the DAA
Genotype 4 chronic hepatitis C (G4 HCV) accounts for 13% of worldwide HCV infections; with 10 million people infected with the virus across the world. Up to the end of 2013, the only treatment option for G4 HCV was treatment with pegylated interferon and ribavirin for 24–48weeks. Since late 2013, treatment of G4 HCV has been transformed by the licensing of many directly acting antiviral agents (DAA). It is an exciting time to be involved in the management of HCV generally and G4 particularly. Interferon-free DAA regimens are now a reality for G4 HCV. This review will highlight these developments and discuss the data behind the use of these drugs. It will also highlight future regimens that are likely to be available over the coming years.

Hepatitis C Treatment and Barriers to Eradication
Although current therapies are highly efficacious, simple, and well-tolerated for most patients, there are gaps in existing therapies. These include suboptimal SVR rates in patients with HCV genotype 3 infection and patients with child C cirrhosis of any genotype. Fortunately, the recent approval of SOF/velpatasvir has in large part addressed gaps in efficacy for patients with genotype 3 infection.11, 12 Patients with end-stage renal disease had until recently remained a subgroup with very limited treatment options, but the approval of daclatasvir and EBR/GZR has been a significant breakthrough for patients with genotype 1 and 4 infections. Impaired renal function remains a significant limitation in therapeutic treatment options for patients with genotype 2, 3, 5, or 6. Treating patients with decompensated cirrhosis remains complex, given their baseline tenuous hepatic function; therefore, it is recommended that they are managed in a liver transplant center.1 Therapeutic options are more restricted for patients with decompensated cirrhosis because several DAAs (simeprevir, dasabuvir, GZR, and EBR) are not approved for use in patients with child B or C cirrhosis, and there is a Food and Drug Administration warning against the use of paritaprevir/ritonavir/ombitasvir. These additional complexities have led to a debate whether treatment should be deferred until after liver transplant as several DAA combination regimens with minimal drug interactions with calcineurin inhibitors are available. On the other hand, SVR has been associated with improvement in liver function and decrease in model for end-stage liver disease score in patients with decompensated cirrhosis, raising the possibility that treatment in the pretransplant setting may obviate the need for transplant.

Six weeks sofosbuvir plus ribavirin is not effective in HCV
News Type: Clinical News
While six weeks of sofosbuvir and ribavirin therapy was safe and well tolerated in HCV patients, its efficacy was sub-optimal, a study concluded. In this open-label study conducted in Australia and New Zealand, 19 adults with recent HCV (68% genotype 1; duration of infection median 37 weeks) received sofosbuvir 400mg daily and weight-based ribavirin for six weeks.
Four reported a symptomatic HCV seroconversion illness, including two with jaundice. At baseline, the median HCV RNA was 5.4 log10 IU/mL and at the end-of-treatment, it was non-quantifiable in 89%. SVR4 and SVR12 were 42% and 32%, respectively. Treatment failure was because of non-response in two, post-treatment relapse in nine, re-infection in one, and with one loss to follow up.
The regimen was well tolerated with minimal haematological toxicity. SVR12 was related to baseline HCV RNA (≤6 log10 IU/mL, p=0.018) and early on-treatment viral kinetics.
The researchers suggest that further research is needed to determine whether more potent interferon-free direct-acting antiviral regimens will allow treatment duration to be shortened in recent, predominantly asymptomatic, HCV infection.

Rapid Virological Response After Early Treatment with a Combined Therapy of Ledipasvir and Sofosbuvir in HCV Genotype 4 After Living Donor Liver Transplantation in a HCC Downstaged
Patient: Case Report and Review of the Literature
Aiman Obed, Abdalla Bashir, Anwar Jarrad Am J Case Rep 2016; 17:672-675 DOI: 10.12659/AJCR.898594
Published: 2016-09-20
BACKGROUND: Hepatitis C virus (HCV) genotype 4 (GT-4) is widespread in the Middle East, where it is responsible for the majority of HCV infections. It shows moderate treatment response rates when compared to other genotypes in the current era of interferon-based regimens. However, in the era of direct acting antiviral (DAA) drugs, its response is at least as good as observed for HCV genotypes 1-3.
CASE REPORT: We present a case of a 44-year-old patient with HCV cirrhosis. Since 2007, he has been treated for HCV infection with multiple ineffective regimens of interferon (INF) and ribavirin. A liver biopsy in 2010 revealed stage 5-6/6 indicating cirrhosis, which was later complicated by the occurrence of portal vein thrombosis and a large hepatocellular carcinoma (HCC) (maximum diameter 9 cm).
The patient was successfully treated with sorafenib, transcatheter arterial chemoembolization (TACE), and radiofrequency ablation. After four TACE procedures, the patient’s AFP (alpha-fetoprotein) decreased remarkably and almost normalized. The HCC disappeared radiologically as shown by triple phase CT, MRI with contrast, and PET-CT.
He successfully underwent a living donor liver transplantation. Four weeks post liver transplantation he started treatment with sorafenib, and switched from tacrolimus to Rapamune (sirolimus) as immunosuppressant therapy. Ten weeks after liver transplantation, HCV treatment was introduced along with ledipasvir and sofosbuvir due to his increasing liver enzyme levels. A rapid viral response was achieved after 14 days. In total, the patient received 12 weeks of this treatment.
CONCLUSIONS: This case study might be of significance in informing early management and personalized treatment of patients with recurrent HCV GT-4 infections after liver transplantation, even in complex clinical surroundings.

HCV Therapy of Genotype 3: Is It Still a Challenge?
Published on07/22/2016
By Ramakrishna Behara and Nancy Reau
Hepatitis C genotype 3 accounts for 30 percent of all infections secondary to hepatitis C and is the second most common genotype worldwide, behind genotype 1. Estimates report that in the U.S., it accounts for 8 to 13 percent of infections. Historically, genotype 3 has been uniquely challenging to manage in large part due to lower response to therapy combined with high rates of steatosis, fibrosis progression and a disproportionately high rate of hepatocellular carcinoma. With the launch of the first wave of interferon-free treatment, many of the direct-acting antivirals (DAA) had higher overall sustained virologic response (SVR) to genotype 3 but did not compare to the SVR rate for treatments approved for genotype 1. Thus, recent drug development has focused on pan-genotypic agents to equalize efficacy across all genotypes.For decades, genotype 3 had been associated with longer treatment and poorer results. Previously, genotype 2 and 3 had been grouped together in management as both responded to interferon-based therapy with higher SVR rates compared to genotype 1. However, several experts suggested separating the genotypes in light of different SVR rates as pegylated interferon (PEG-IFN) plus ribavirin was achieving SVR rates as high as 93 percent for genotype 2 compared to 65 to 80 percent for genotype 3. With the approval of the first DAAs — telaprevir and boceprevir — treatment efficacy significantly improved in HCV genotype 1 patients but had no impact on genotype 3.
Since then, several all-oral regimens have been approved for the treatment of HCV, many of which have efficacy against genotype 3 infection, including sofosbuvir (a nonstructural protein 5B inhibitor) plus ribavirin for 24 weeks as demonstrated in the FISSION, FUSION, POSITRON and VALENCE trials and more recently daclatasvir (nonstructural protein 5A inhibitor) plus sofosbuvir. Tolerability and efficacy improved dramatically, but SVR rates still failed to achieve rates similar to those with other genotypes, especially in challenging populations such as those with cirrhosis. Strategies to improve viral eradication included the addition of PEG-IFN, extension of therapy to 24 weeks and the addition of ribavirin, yet real-world data showed that SVR rates often fell below 90 percent and below 80 percent in those with more advanced disease. The recent push to develop pan-genotypic regimens with simple algorithms is erasing this gap.
On June 28, 2016, FDA approved the pan-genotypic, fixed-dose combination of sofosbuvir/velpatasvir for the treatment of HCV. Given once daily for 12 weeks despite genotype, this is again a major advance for individuals with hepatitis C, especially those with genotype 3.
The ELECTRON-2 trial investigated the use of the NS5A inhibitor velpatasvir, with sofosbuvir and demonstrated a 96 to 100 percent SVR12 rate in genotype 3 treatment-naïve patients without cirrhosis. This success was further supported in the Phase 3 ASTRAL-3 trial, which revealed a 95 percent SVR 12 using the combination of sofosbuvir and velpatasvir for 12 weeks in 277 treatment-naïve and experienced genotype 3 patients, including 30 percent with cirrhosis.
This regimen was superior to sofosbuvir and ribavirin for 24 weeks, which achieved SVR in only 80 percent of 275 subjects. Other promising pan-genotypic combinations include the nonstructural protein 5A inhibitor ABT-530 and the NS3/4A ABT 530, which recently demonstrated 100 percent SVR12 rates with eight weeks of therapy in treatment-naïve genotype 3 without cirrhosis and with 12 weeks of therapy for treatment-naïve patients with cirrhosis.
The transition of therapy from an interferon-and-ribavirin-based regimen to DAA treatments has resulted in a marked improvement in eradicating genotype 1 infection. As a result, genotype 3 has emerged not only as the most virulent but also as the most difficult genotype to treat. The success of sofosbuvir in combination with agents such as daclatasvir has provided more avenues for treatment in patients with genotype 3 infections
Though barriers in treatment still exist, including the high cost of therapy, the success of more recent trials holds promise that equal success to treating genotype 1 may be seen in the near future for genotype 3. In particular, the combination of pan-genotypic agents has a goal to shorten treatment courses while eliminating the need for ribavirin and providing high rates of SVR. Thus, while there is a pressing need to improve treatment options for genotype 3, new opportunities are on the horizon.

BACKGROUND & AIMS:
Few studies have examined factors associated with disease progression in hepatitis C virus (HCV) infection. We examined the association of 11 risk factors with adverse outcomes in a population-based prospective cohort observational study of Alaska Native/American Indian persons with chronic HCV infection.
METHODS:
We collected data from a population-based cohort study of liver-related adverse outcomes of infection in American Indian/Alaska Native persons with chronic HCV living in Alaska, recruited from 1995 through 2012. We calculated adjusted hazard ratios (aHR) and 95% CIs for end-stage liver disease (ESLD; presence of ascites, esophageal varices, hepatic encephalopathy, or coagulopathy), hepatocellular carcinoma (HCC), and liver-related death using a Cox proportional hazards model.
RESULTS:
We enrolled 1080 participants followed for 11,171 person-years (mean, 10.3 years); 66%, 19%, and 14% were infected with HCV genotypes 1, 2, and 3, respectively. On multivariate analysis, persons infected with HCV genotype 3 had a significantly increased risk of developing all 3 adverse outcomes. Their aHR for ESLD was 2.1 (95% CI, 1.5-3.0), aHR for HCC was 3.1 (95% CI, 1.4-6.6), and aHR for liver-related death was 2.4 (95% CI, 1.5-4.0) compared to genotype 1. Heavy alcohol use was an age-adjusted risk factor for ESLD (aHR, 2.2; 95% CI, 1.6-3.2), and liver-related death (aHR: 2.9; 95% CI, 1.8-4.6). Obesity was a risk factor for ESLD (aHR, 1.4; 95% CI, 1.0-1.9, and diabetes was a risk factor for ESLD (aHR, 1.5; 95% CI, 1.1-2.2). Male sex was a risk factor for HCC (aHR, 3.6; 95% CI, 1.6-8.2).
CONCLUSIONS:
In a population-based cohort study of American Indian/Alaska Native persons with chronic HCV infection, we found those infected with HCV genotype 3 to be at high risk for ESLD, HCC, and liver-related death.

AbstractBackground: An interferon-free regimen including sofosbuvir and ribavirin (RBV) for patients with hepatitis C virus (HCV) genotype 2 (G2) infection leads to a drastic improvement of sustained virological response (SVR). However, the safety, tolerability, and efficacy in patients aged 75 or older have not been completely understood.Summary: Fifty-six patients with HCV G2 infection who were treated with sofosbuvir and weight-based dose of RBV were enrolled. Thirty-seven patients aged ≥75 and 19 patients aged ≤74 were classified as the aged and non-aged groups, respectively. The aged group was characterized by significantly more number of women, history of hepatocellular carcinoma, low serum albumin (ALB) level, low hemoglobin (Hb) concentration, low estimated glomerular filtration rate (eGFR), and high fibrosis-4 index (p = 0.0029). Forty-one patients were evaluated for SVR at 12 weeks after the end of therapy (SVR12); of them, all but one completed the treatment scheduled for 12 weeks. The aged group showed lower SVR12 rate than the non-aged group (81.3% for aged and 96.0% for non-aged groups). Although the Hb concentration and eGFR are significantly lower in the aged group throughout the clinical course, all patients in the aged group completed the 12-week treatment with a gradual increase of serum ALB level.Key Messages: The combination of sofosbuvir plus RBV is tolerable and beneficial in patients aged >75. However, intensive management of anemia by dose reduction of RBV is necessary, which could lead to a low SVR12 rate compared to that observed in patients younger than 75 years.

Effectiveness of Elbasvir and Grazoprevir, With or Without Ribavirin, Treatment-Experienced Patients with Chronic Hepatitis C Infection
The combination tablet of elbasvir and grazoprevir, with or without ribavirin, was highly efficacious in inducing an SVR12 in patients with HCV genotype 1, 4, or 6 infection failed by previous treatment with peg-interferon and ribavirin, including patients with cirrhosis and/or a prior null response
Zepatier less costly, more effective than Harvoni, Epclusa for Hepatitis C
According to recent research presented at AMCP Nexus 2016, hepatitis C genotype 1 treatment with Zepatier (elbasvir/grazoprevir; Merck) was more effective and less expensive when compared to Harvoni (ledipasvir/sofosbuvir; Gilead) and Epclusa (sofosbuvir/velpatasvir; Gilead).
New hepatitis C product covers all six genotypes
When asked about the current HCV market and evidence-based treatment recommendations to manage this disease, C. Wayne Weart, PharmD, BCPS, FASHP, FAPhA, a professor of clinical pharmacy and outcome sciences at South Carolina College of Pharmacy, told Pharmacy Today that, based upon the updated guidelines from July 2016 and the new FDA-approved hepatitis C once-a-day, single-pill medications, “I am suggesting that the following agents replace ledipasvir and sofosbuvir (Harvoni—Gilead), which costs approximately $95,000 for 12 weeks of therapy and even more if you need 24 weeks of therapy. The most cost-effective therapy for patients who are candidates for and can take it would be Merck’s elbasvir and grazoprevir tablets (Zepatier).” According to Weart, the cost is approximately $55,000 for 12 weeks of therapy.Weart recommended that treatment-naive patients with no cirrhosis and genotype 1a infection undergo testing for virus with NS5A resistance–associated variant polymorphisms (RAVs) to determine the best therapy. If no baseline NS5A RAVs are present, monotherapy for 12 weeks with elbasvir and grazoprevir should be given, but if baseline NS5A RAVs are present, ribavirin should be added to 16 weeks of treatment with elbasvir and grazoprevir. Patients with genotype 1b or 4 should receive elbasvir and grazoprevir once daily for 12 weeks.
“For those with genotypes 2, 3, 5, and 6, I would recommend this new therapy, sofosbuvir and velpatasvir, to be given for 12 weeks, which comes in at an approximate cost of $75,000,” said Weart.

Review article on management of hepatitis C genotype 4 in the DAA
Genotype 4 chronic hepatitis C (G4 HCV) accounts for 13% of worldwide HCV infections; with 10 million people infected with the virus across the world. Up to the end of 2013, the only treatment option for G4 HCV was treatment with pegylated interferon and ribavirin for 24–48weeks. Since late 2013, treatment of G4 HCV has been transformed by the licensing of many directly acting antiviral agents (DAA). It is an exciting time to be involved in the management of HCV generally and G4 particularly. Interferon-free DAA regimens are now a reality for G4 HCV. This review will highlight these developments and discuss the data behind the use of these drugs. It will also highlight future regimens that are likely to be available over the coming years.

Hepatitis C Treatment and Barriers to Eradication
Although current therapies are highly efficacious, simple, and well-tolerated for most patients, there are gaps in existing therapies. These include suboptimal SVR rates in patients with HCV genotype 3 infection and patients with child C cirrhosis of any genotype. Fortunately, the recent approval of SOF/velpatasvir has in large part addressed gaps in efficacy for patients with genotype 3 infection.11, 12 Patients with end-stage renal disease had until recently remained a subgroup with very limited treatment options, but the approval of daclatasvir and EBR/GZR has been a significant breakthrough for patients with genotype 1 and 4 infections. Impaired renal function remains a significant limitation in therapeutic treatment options for patients with genotype 2, 3, 5, or 6. Treating patients with decompensated cirrhosis remains complex, given their baseline tenuous hepatic function; therefore, it is recommended that they are managed in a liver transplant center.1 Therapeutic options are more restricted for patients with decompensated cirrhosis because several DAAs (simeprevir, dasabuvir, GZR, and EBR) are not approved for use in patients with child B or C cirrhosis, and there is a Food and Drug Administration warning against the use of paritaprevir/ritonavir/ombitasvir. These additional complexities have led to a debate whether treatment should be deferred until after liver transplant as several DAA combination regimens with minimal drug interactions with calcineurin inhibitors are available. On the other hand, SVR has been associated with improvement in liver function and decrease in model for end-stage liver disease score in patients with decompensated cirrhosis, raising the possibility that treatment in the pretransplant setting may obviate the need for transplant.

Six weeks sofosbuvir plus ribavirin is not effective in HCV
News Type: Clinical News
While six weeks of sofosbuvir and ribavirin therapy was safe and well tolerated in HCV patients, its efficacy was sub-optimal, a study concluded. In this open-label study conducted in Australia and New Zealand, 19 adults with recent HCV (68% genotype 1; duration of infection median 37 weeks) received sofosbuvir 400mg daily and weight-based ribavirin for six weeks.
Four reported a symptomatic HCV seroconversion illness, including two with jaundice. At baseline, the median HCV RNA was 5.4 log10 IU/mL and at the end-of-treatment, it was non-quantifiable in 89%. SVR4 and SVR12 were 42% and 32%, respectively. Treatment failure was because of non-response in two, post-treatment relapse in nine, re-infection in one, and with one loss to follow up.
The regimen was well tolerated with minimal haematological toxicity. SVR12 was related to baseline HCV RNA (≤6 log10 IU/mL, p=0.018) and early on-treatment viral kinetics.
The researchers suggest that further research is needed to determine whether more potent interferon-free direct-acting antiviral regimens will allow treatment duration to be shortened in recent, predominantly asymptomatic, HCV infection.

Rapid Virological Response After Early Treatment with a Combined Therapy of Ledipasvir and Sofosbuvir in HCV Genotype 4 After Living Donor Liver Transplantation in a HCC Downstaged
Patient: Case Report and Review of the Literature
Aiman Obed, Abdalla Bashir, Anwar Jarrad Am J Case Rep 2016; 17:672-675 DOI: 10.12659/AJCR.898594
Published: 2016-09-20
BACKGROUND: Hepatitis C virus (HCV) genotype 4 (GT-4) is widespread in the Middle East, where it is responsible for the majority of HCV infections. It shows moderate treatment response rates when compared to other genotypes in the current era of interferon-based regimens. However, in the era of direct acting antiviral (DAA) drugs, its response is at least as good as observed for HCV genotypes 1-3.
CASE REPORT: We present a case of a 44-year-old patient with HCV cirrhosis. Since 2007, he has been treated for HCV infection with multiple ineffective regimens of interferon (INF) and ribavirin. A liver biopsy in 2010 revealed stage 5-6/6 indicating cirrhosis, which was later complicated by the occurrence of portal vein thrombosis and a large hepatocellular carcinoma (HCC) (maximum diameter 9 cm).
The patient was successfully treated with sorafenib, transcatheter arterial chemoembolization (TACE), and radiofrequency ablation. After four TACE procedures, the patient’s AFP (alpha-fetoprotein) decreased remarkably and almost normalized. The HCC disappeared radiologically as shown by triple phase CT, MRI with contrast, and PET-CT.
He successfully underwent a living donor liver transplantation. Four weeks post liver transplantation he started treatment with sorafenib, and switched from tacrolimus to Rapamune (sirolimus) as immunosuppressant therapy. Ten weeks after liver transplantation, HCV treatment was introduced along with ledipasvir and sofosbuvir due to his increasing liver enzyme levels. A rapid viral response was achieved after 14 days. In total, the patient received 12 weeks of this treatment.
CONCLUSIONS: This case study might be of significance in informing early management and personalized treatment of patients with recurrent HCV GT-4 infections after liver transplantation, even in complex clinical surroundings.

HCV Therapy of Genotype 3: Is It Still a Challenge?
Published on07/22/2016
By Ramakrishna Behara and Nancy Reau
Hepatitis C genotype 3 accounts for 30 percent of all infections secondary to hepatitis C and is the second most common genotype worldwide, behind genotype 1. Estimates report that in the U.S., it accounts for 8 to 13 percent of infections. Historically, genotype 3 has been uniquely challenging to manage in large part due to lower response to therapy combined with high rates of steatosis, fibrosis progression and a disproportionately high rate of hepatocellular carcinoma. With the launch of the first wave of interferon-free treatment, many of the direct-acting antivirals (DAA) had higher overall sustained virologic response (SVR) to genotype 3 but did not compare to the SVR rate for treatments approved for genotype 1. Thus, recent drug development has focused on pan-genotypic agents to equalize efficacy across all genotypes.For decades, genotype 3 had been associated with longer treatment and poorer results. Previously, genotype 2 and 3 had been grouped together in management as both responded to interferon-based therapy with higher SVR rates compared to genotype 1. However, several experts suggested separating the genotypes in light of different SVR rates as pegylated interferon (PEG-IFN) plus ribavirin was achieving SVR rates as high as 93 percent for genotype 2 compared to 65 to 80 percent for genotype 3. With the approval of the first DAAs — telaprevir and boceprevir — treatment efficacy significantly improved in HCV genotype 1 patients but had no impact on genotype 3.
Since then, several all-oral regimens have been approved for the treatment of HCV, many of which have efficacy against genotype 3 infection, including sofosbuvir (a nonstructural protein 5B inhibitor) plus ribavirin for 24 weeks as demonstrated in the FISSION, FUSION, POSITRON and VALENCE trials and more recently daclatasvir (nonstructural protein 5A inhibitor) plus sofosbuvir. Tolerability and efficacy improved dramatically, but SVR rates still failed to achieve rates similar to those with other genotypes, especially in challenging populations such as those with cirrhosis. Strategies to improve viral eradication included the addition of PEG-IFN, extension of therapy to 24 weeks and the addition of ribavirin, yet real-world data showed that SVR rates often fell below 90 percent and below 80 percent in those with more advanced disease. The recent push to develop pan-genotypic regimens with simple algorithms is erasing this gap.
On June 28, 2016, FDA approved the pan-genotypic, fixed-dose combination of sofosbuvir/velpatasvir for the treatment of HCV. Given once daily for 12 weeks despite genotype, this is again a major advance for individuals with hepatitis C, especially those with genotype 3.
The ELECTRON-2 trial investigated the use of the NS5A inhibitor velpatasvir, with sofosbuvir and demonstrated a 96 to 100 percent SVR12 rate in genotype 3 treatment-naïve patients without cirrhosis. This success was further supported in the Phase 3 ASTRAL-3 trial, which revealed a 95 percent SVR 12 using the combination of sofosbuvir and velpatasvir for 12 weeks in 277 treatment-naïve and experienced genotype 3 patients, including 30 percent with cirrhosis.
This regimen was superior to sofosbuvir and ribavirin for 24 weeks, which achieved SVR in only 80 percent of 275 subjects. Other promising pan-genotypic combinations include the nonstructural protein 5A inhibitor ABT-530 and the NS3/4A ABT 530, which recently demonstrated 100 percent SVR12 rates with eight weeks of therapy in treatment-naïve genotype 3 without cirrhosis and with 12 weeks of therapy for treatment-naïve patients with cirrhosis.
The transition of therapy from an interferon-and-ribavirin-based regimen to DAA treatments has resulted in a marked improvement in eradicating genotype 1 infection. As a result, genotype 3 has emerged not only as the most virulent but also as the most difficult genotype to treat. The success of sofosbuvir in combination with agents such as daclatasvir has provided more avenues for treatment in patients with genotype 3 infections
Though barriers in treatment still exist, including the high cost of therapy, the success of more recent trials holds promise that equal success to treating genotype 1 may be seen in the near future for genotype 3. In particular, the combination of pan-genotypic agents has a goal to shorten treatment courses while eliminating the need for ribavirin and providing high rates of SVR. Thus, while there is a pressing need to improve treatment options for genotype 3, new opportunities are on the horizon.

Safety, Efficacy, and Tolerability of Sofosbuvir and Ribavirin in Management of Recurrent Hepatitis C Virus Genotype 4 After Living Donor Liver Transplant in Egypt: What Have We Learned so far?
April 29
Objectives: The aim of this study was to evaluate the efficacy, safety, and tolerability of sofosbuvir and ribavirin in LDLT recipients with recurrent HCV genotype 4.,Patients and Methods: Thirty-nine Egyptian LDLT recipients were treated for recurrent HCV after LDLT with nucleos(t)ide analog NS5B polymerase inhibitor, sofosbuvir, and ribavirin without pegylated interferon for 6 months (November 2014 to June 2015) in this intention-to-treat analysis.,Results: One recipient died 1 week after starting the treatment, but the remaining 38 patients completed 24 weeks of treatment and were then followed for 12 weeks after end of treatment (EOT). The sustained virological response (SVR) at week 12 after EOT was achieved in 76% (29/38) of recipients. SVR was significantly higher in treatment-naïve patients and in recipients with a low stage of fibrosis. Only 2 (5%) recipients developed severe pancytopenia and acute kidney injury.,Conclusions: We recommend initiating treatment as soon as possible after liver transplantation with newer combinations, such as ledipasvir/sofosbuvir or sofosbuvir/simeprevir, rather than sofosbuvir with Ribavirin, to achieve higher rates of SVR.,Background: Recurrence of HCV after living donor liver transplant (LDLT) is nearly universal, with almost one third of recipients developing cirrhosis and graft failure within 5 years after LDLT. Different studies have been published on the effect of sofosbuvir after liver transplantation on recurrent HCV with different genotypes.

Safety, Efficacy, and Tolerability of Sofosbuvir and Ribavirin in Management of Recurrent Hepatitis C Virus Genotype 4 After Living Donor Liver Transplant in Egypt: What Have We Learned so far?
April 29
Objectives: The aim of this study was to evaluate the efficacy, safety, and tolerability of sofosbuvir and ribavirin in LDLT recipients with recurrent HCV genotype 4.,Patients and Methods: Thirty-nine Egyptian LDLT recipients were treated for recurrent HCV after LDLT with nucleos(t)ide analog NS5B polymerase inhibitor, sofosbuvir, and ribavirin without pegylated interferon for 6 months (November 2014 to June 2015) in this intention-to-treat analysis.,Results: One recipient died 1 week after starting the treatment, but the remaining 38 patients completed 24 weeks of treatment and were then followed for 12 weeks after end of treatment (EOT). The sustained virological response (SVR) at week 12 after EOT was achieved in 76% (29/38) of recipients. SVR was significantly higher in treatment-naïve patients and in recipients with a low stage of fibrosis. Only 2 (5%) recipients developed severe pancytopenia and acute kidney injury.,Conclusions: We recommend initiating treatment as soon as possible after liver transplantation with newer combinations, such as ledipasvir/sofosbuvir or sofosbuvir/simeprevir, rather than sofosbuvir with Ribavirin, to achieve higher rates of SVR.,Background: Recurrence of HCV after living donor liver transplant (LDLT) is nearly universal, with almost one third of recipients developing cirrhosis and graft failure within 5 years after LDLT. Different studies have been published on the effect of sofosbuvir after liver transplantation on recurrent HCV with different genotypes.

Recent advances in managing chronic HCV infection: focus on therapy in patients with severe liver disease
There are extensive data from phase III or IV studies on the efficacy of IFN-free regimens, but patients with compensated and decompensated cirrhosis were often underrepresented. Currently, more data are emerging from real-world studies on the efficacy of these regimens, which included patients with the most severe cirrhosis. Table 1–Table 4 show the data from phase III or IV studies available on the efficacy of IFN-free antiviral therapy. Here we will discuss the treatment regimens in a more conceptual way for the treatment of patients with compensated cirrhosis.
