Hepatitis C debrief: Therapy has matured, access issues remain
SAN FRANCISCO – Hepatitis C therapy has matured and now offers excellent sustained viral response (SVR) in the vast majority of cases, but key challenges remain in getting the therapy to those who need it.
“Unfortunately, we’re not making some of the progress we might have hoped to see, particularly in North America,” said Jordan Feld, MD, MPH, who gave a debrief of hepatitis C abstracts during a wrap-up session at the annual meeting of the American Association for the Study of Liver Diseases.
The problem is particularly acute in young adults aged 18-39 years – only about 9% of those who tested positive for HCV RNA saw a specialist, and about 23% of those who saw a specialist went on to receive treatment, according to an analysis of over 17 million patients in the United States (abstract 1567). The numbers were better for older adults but still far from optimal, with 23% who tested positive seeing a specialist, and just 32% of those patients getting treatment.
Another study (abstract 0147) looked state by state at the percentage of Medicaid patients who received a prescription for direct-acting antiviral (DAA) medication and then went on to fill the prescription. The rates ranged from 0% in Alaska to 96% in Connecticut. Eight states were higher than 70%, six were between 50% and 70%, and 15 states were below 50%.
“Despite our efforts, there continue to be major access barriers across the U.S., particularly for Medicaid individuals,” said Dr. Feld, who is a clinician-scientist at the Toronto Western Hospital Liver Clinic and the McLaughlin-Rotman Centre for Global Health.
A study examining the Chronic Hepatitis (CHeCS) cohort (abstract 0585) described a big spike in treatment uptake shortly after approvals of the new HCV regimens, but by 2016, only about one-third of individuals who required treatment actually began treatment. Factors associated with nontreatment largely reflected marginalization, including low income, being on Medicaid, and lack of long-term follow-up.
Even as health systems struggle to get treatment to those who need it, new studies are showing how to expand existing treatments into new populations.
Results from the EXPEDITION 8 study (abstract LB-7) showed efficacy of an 8-week regimen of the glecaprevir/pibrentasvir combination in patients with compensated cirrhosis. It looked at genotypes 1, 2, and 4-6. In an intention-to-treat analysis, 98% attained SVR and there were no viral failures or safety concerns. A follow-up trial is ongoing that includes patients with genotype 3. “This is exciting to be able to shorten therapy in patients with cirrhosis,” said Dr. Feld.
Although first-line DAAs are extremely effective, there are a few patients who do not achieve a cure. One study (abstract 0227) examined the combination of sofosbuvir, velpatasvir, and voxilaprevir in retreatment of these patients. The drugs resulted in SVR rates similar to those in registration trials, but the regimen was somewhat less effective in patients previously treated with sofosbuvir and velpatasvir. “I think we need to investigate that further,” said Dr. Feld.
The combination of glecaprevir and pibrentasvir also proved effective for retreatment in patients with genotype 1/1A who had failed treatment with an NS5A inhibitor plus sofosbuvir with or without ribavirin (abstract 226). SVR rates at 16 weeks were quite good, but lower in genotype 1a patients at 12 weeks (87% week 12 versus 94% week 16).”I think this is a really good regimen for genotype 1b. For 1a, serum definitely needs 16 weeks [to clear],” said Dr. Feld.
Other abstracts presented at the meeting detailed some of the benefits of SVR, not all of which are broadly appreciated. An analysis of the Hepatitis Testers Cohort in British Columbia (abstract 145), which includes over 7,000 patients who were followed for a median of 2 years (DAA) or 9.5 years (interferon-based), showed survival advantages to SVR in both cirrhotic (adjusted hazard ratio, 0.14) and noncirrhotic patients (aHR, 0.13). Other benefits include lower risk of diabetes (aHR, 0.53), chronic kidney disease/endstage renal disease (aHR, 0.48), stroke (aHR, 0.67), and mood and anxiety disorders (aHR, 0.53) (abstract 148).
As is generally accepted, SVR reduces the risk of hepatocellular cancer (HCC), according to analyses of VA and Gilead data (abstract 635), with a benefit in both cirrhotic and noncirrhotic patients. The risk almost disappears in patients without cirrhosis (incidence rate 0.07 per 100 person-years and is curbed in cirrhotic patients (incidence rate 1.30 in compensated, 4.05 in decompensated cirrhosis).
“There is really very significantly high incidence in cancer in decompensated cirrhosis, which just highlights that these patients continue to need ongoing surveillance. Although there have been efforts at developing strategies to risk stratify patients with cirrhosis, at least for now we’re stuck with surveillance, but I think for patients without cirrhosis there are now enough data showing a low enough incidence of primary HCC that we can probably avoid surveillance in that group,” said Dr. Feld.
Injectable drug users represent a special challenge in hepatitis C treatment, but new studies show cause for optimism in this population. These patients are harder to reach, and they may be less medication compliant, but one study (abstract 1632) found that imperfect adherence doesn’t necessarily undermine results – in a 12-week regimen, patients who didn’t finish until 14 weeks had no significant difference in SVR rates.
“So these therapies have a bit of forgiveness. We probably shouldn’t tell that to the patients, but it’s reassuring that we can use these therapies even in tough-to-reach populations,” said Dr. Feld.

High rates of HCV treatment completion seen in people who inject drugs
SAN FRANCISCO – , preliminary results from an ongoing study showed.
“Both from a public health and a human rights perspective, hepatitis C elimination in people who inject drugs is critical,” study coauthor Elana Rosenthal, MD, said during a press briefing at the annual meeting of the American Association for the Study of Liver Diseases. “People who inject drugs are the main progenitors of ongoing transmission of hepatitis C. However, they are often denied access to hepatitis C treatment due to concerns about their ability to take medication consistently and achieve cure. This is especially true amongst patients with challenging demographic factors, frequent drug use, and those not on treatment for opioid use disorder. However, there are limited data on hepatitis C adherence in people who inject drugs outside of vigorous clinical trial settings.”
In an effort to understand whether a marginalized population with ongoing injection drug use could adhere to HCV treatment, and how this adherence would impact cure, Dr. Rosenthal and her associates enrolled 100 subjects in ANCHOR, a single-center study evaluating HCV treatment in patients who have chronic HCV, opioid use disorder, and ongoing injection drug use. “We did not preferentially enroll patients who we thought we would be most likely to cure, and we did not exclude patients who seemed unlikely to adhere to treatment,” said Dr. Rosenthal, codirector of the DC Partnership for HIV/AIDS Progress hepatitis clinical research program at the University of Maryland, Baltimore. “All patients were treated with sofosbuvir/velpatasvir, with a plan to complete 12 weeks of treatment.” Medication was dispensed monthly in bottles containing 28 pills, and patients were seen for monthly visits, mirroring standard clinical care for HCV. The researchers monitored patients for medication adherence through pill counts and evaluated them for hepatitis C cure 12 weeks after treatment.
The median age of the 100 patients was 57 years, 76% were black, 33% had cirrhosis, 51% were unstably housed, 92% had a history of incarceration, and 92% had no income source or relied exclusively on government benefits. “The patients represent an incredibly marginalized population,” she said. At baseline, 58% reported daily or more frequent injection drug use, 33% reported medication-assisted treatment, 29% shared injection drug use equipment within the past 3 months, and 40% met criteria for hazardous drinking based on the Alcohol Use Disorders Identification Test (AUDIT-C).
Of the 100 patients, 59 received 12 weeks of treatment. Of these 59 patients, 28 finished 1-7 days after the anticipated end date, 9 finished between 8 and 14 days late, and 9 patients finished more than 14 days late.
Of the 58 patients who attended an office visit at week 24 of their treatment, 52 (90%) achieved a sustained virologic response. This cure rate was associated with having an HCV viral load less than 200 IU/mL at week 4, and with taking 12 weeks of treatment. Nonsustained virologic response was driven by virologic failure, loss to follow-up, and death.
When the researchers compared subjects who achieved sustained virologic response with those who did not, baseline demographics including frequent drug use, unstable housing status, and not being on medication to treat opioid use disorder were not associated with decreased cure rates. “While we found high rates of treatment completion in this population, because of external factors such as incarceration, hospitalization, and having medications stolen, 13 patients had interruptions in treatment,” Dr. Rosenthal said. “Further, while 21 patients had near-perfect medication adherence, 46 patients took longer than 12 weeks to complete the full treatment course due to intermittent missed doses. However, as long as patients completed the prescribed amount, imperfect adherence was not associated with decreased cure rates.”
Based on ANCHOR’s preliminary results, Dr. Rosenthal concluded that concerns about HCV treatment adherence such as baseline housing status, drug use frequency, and being on medication for opioid use disorder “are not likely to influence treatment outcome of HCV and should not be used to justify exclusion from treatment in this population. The ANCHOR investigation adds to the growing body of literature supporting expansion of HCV treatment to all patients, including people who inject drugs. Treatment of people who inject drugs is a critical factor in HCV elimination and, most importantly, reducing morbidity and mortality in this population.”

High rates of prescription opioid, benzodiazepine use observed in chronic liver disease
SAN FRANCISCO – .
“Middle-aged individuals and those with a background of substance abuse and mental health conditions appear to have highest rates of use and represent populations for which targeted interventions to curb use could be highest yield,” lead study author Monica Konerman, MD, said in an interview in advance of the annual meeting of the American Association for the Study of Liver Diseases.
In an effort to better understand the rates of prescription opioid and benzodiazepine use in chronic liver disease, Dr. Konerman, director of the Michigan Medicine NAFLD Clinic at the University of Michigan, Ann Arbor, and her colleagues drew from the Truven Health Analytics Marketscan databases from 2009 to 2015. They limited the analysis to individuals with drug coverage who had chronic hepatitis C (HCV) without cirrhosis, cirrhosis, congestive heart failure (CHF), or chronic obstructive pulmonary disease (COPD), and examined pharmacy files for outpatient prescriptions.
Dr. Konerman reported data from 210,191 patients with HCV, 79,332 with cirrhosis, 766,840 with CHF, and 1,438,798 with COPD. Their median age was 59 years, and 51% were female. In per person-years, the prevalence of prescription opioid use was 25% among patients with chronic HCV, 53% among patients with cirrhosis, 26% among those with CHF, and 24% among those with COPD. At the same time, in per person-years, the prevalence of benzodiazepine use was 12% among patients with chronic HCV, 21% among patients with cirrhosis, 12% among those with CHF, and 13% among those with COPD. Use of opioids was greatest in adults 40-59 years of age (P less than .001). High-dose opioid use, defined as 100 opioid morphine equivalents per day or greater, occurred in 23% of those with cirrhosis and in 22% of those with HCV.
“The significant increase in rates of use in chronic liver disease, compared to other chronic conditions was remarkable, particularly given that patients with liver disease are at higher risk for adverse consequences of use due to hepatic metabolism of these medications,” Dr. Konerman said.
She went on to acknowledge “inherent limitations to studies that are secondary database analyses that rely on diagnosis codes for categorization of disease with potential for both over and under classification. We also did not capture inpatient prescriptions,” she said.
Dr. Konerman reported having no financial disclosures.

They limited the analysis to individuals with drug coverage who had chronic hepatitis C (HCV) without cirrhosis, cirrhosis, congestive heart failure (CHF), or chronic obstructive pulmonary disease (COPD), and examined pharmacy files for outpatient prescriptions.
Dr. Konerman reported data from 210,191 patients with HCV, 79,332 with cirrhosis, 766,840 with CHF, and 1,438,798 with COPD. Their median age was 59 years, and 51% were female. In per person-years, the prevalence of prescription opioid use was 25% among patients with chronic HCV, 53% among patients with cirrhosis, 26% among those with CHF, and 24% among those with COPD. At the same time, in per person-years, the prevalence of benzodiazepine use was 12% among patients with chronic HCV, 21% among patients with cirrhosis, 12% among those with CHF, and 13% among those with COPD. Use of opioids was greatest in adults 40-59 years of age (P less than .001). High-dose opioid use, defined as 100 opioid morphine equivalents per day or greater, occurred in 23% of those with cirrhosis and in 22% of those with HCV.
“The significant increase in rates of use in chronic liver disease, compared to other chronic conditions was remarkable, particularly given that patients with liver disease are at higher risk for adverse consequences of use due to hepatic metabolism of these medications,” Dr. Konerman said.
She went on to acknowledge “inherent limitations to studies that are secondary database analyses that rely on diagnosis codes for categorization of disease with potential for both over and under classification. We also did not capture inpatient prescriptions,” she said.

The Liver Meeting 2016 debrief – key abstracts
BOSTON – Amid a plethora of quality research, several abstracts stood out at the annual meeting of the American Association for the Study of Liver Diseases, Arun J. Sanyal, MD, said during the final debrief.
He focused first on nonalcoholic fatty liver disease (NAFLD), which has lacked rigorous studies of disease evolution. Consequently, “current therapeutic development is based on small retrospective data sets with heterogenous populations,” Dr. Sanyal said. Therefore, he and his associates correlated serial biopsies with clinical data (abstract 37). The results confirmed the waxing and waning nature of NAFLD and linked regressing or progressive fibrosis to several factors, including NAFLD Disease Activity score (NAS). NAFLD and nonalcoholic steatohepatitis (NASH) are “not two different diseases, it’s the same disease,” Dr. Sanyal said. “Establishing disease activity as a driver of disease progression is highly relevant for development of noninvasive biomarkers, and also gives us a foundation for the development of clinical trials in this space.”
Several studies of NASH biomarkers yielded notable results at the meeting. In the largest study to date of circulating microRNAs as markers of NASH, (LB2) the miRNAs 34a, 122a, and 200a distinguished patients with and without NAS scores of at least 4 and at least stage 2 fibrosis with areas under the receiver operating characteristic curve (AUROC) between 0.59 and 0.80. “MicroRNAs appear promising, but likely need to be combined with additional biomarkers,” Dr. Sanyal said.
He also noted a study (abstract 40) in which metabolomics of liquid biopsies comprehensively evaluated NAFLD, including fibrosis stage, with AUROCs up to 0.95. Metabolomics “holds promise as a diagnostic tool that can be operationalized for point-of-care testing,” he said.
When it comes to NAFLD, hepatologists “often struggle with what to tell our patients about alcohol,” Dr. Sanyal said. To help clarify the issue, abstract 31 compared NAFLD patients who did or did not report habitually consuming up to two drinks a day in formal prospective questionnaires. After adjustment for baseline histology, abstainers and modest drinkers did not differ on any measure of histologic change, except that abstainers had a greater decrease in steatosis on follow-up biopsy. These findings negate several retrospective studies by suggesting that alcohol consumption does not positively affect the trajectory of NAFLD, Dr. Sanyal concluded.
Many new compounds for treating NASH are in early development, he noted. Among those further along the pipeline, the immunomodulator and CCR2/CCR5 inhibitor cenicriviroc (CVC) missed its primary endpoint (improved NAS and no worsening of fibrosis) but was associated with significantly improved fibrosis without worsening of NASH in the phase 2b CENTAUR study (LB1).
“We also saw highly promising evidence for the effects of ASK1 [apoptosis signal regulating kinase] inhibition on hepatic fibrosis and disease activity in NASH,” Dr. Sanyal added. In a randomized phase II trial (LB3), the ASK1 inhibitor GS-4997 was associated with significant improvement in fibrosis without worsening of NASH when given in combination with simtuzumab, and also improved liver stiffness and magnetic resonance imaging–estimated proton density fat fraction (MRI-PDFF). “These very promising and exciting results need confirmation in more advanced, placebo-controlled trials,” Dr. Sanyal said.
Studies of alcohol use disorders of the liver confirmed that prednisolone has marginal benefits, that the benefits of steroids in general are offset by sepsis, and that pentoxifylline produced no mortality benefit, Dr. Sanyal noted. In studies of primary biliary cirrhosis, the farnesoid-X receptor agonist obeticholic acid (OCA), which was approved by the Food and Drug Administration in 2016, was associated with significantly improved AST to Platelet Ratio Index (APRI) and liver stiffness measures by transient elastography at doses of 10 mg or titrated from 5 mg to 10 mg, with or without ursodeoxycholic acid (abstract 209). In another study, patients with PBC who received norUDCA, a side chain–shortened version of UDCA, experienced decreases in serum ALP levels that were dose dependent and differed significantly from trends in the placebo group (abstract 210).
In another study, the investigational ileal bile acid transporter inhibitor GSK2330672 was associated with significant reductions in itch, compared with placebo, and with lower serum bile acids among pruritic PBC patients (abstract 205). Treatment was associated with diarrhea, but it was usually mild and transient.
Dr. Sanyal concluded by reviewing several studies of cirrhosis and hepatic encephalopathy. In a prospective randomized controlled trial (abstract 247), lactulose with albumin significantly outperformed lactulose monotherapy for reversing hepatic encephalopathy, reducing hospital stays, and preventing mortality, especially sepsis-related death.
In another multicenter, 24-week, phase IV open-label study (abstract 248), 25% of patients experienced breakthrough hepatic encephalopathy when treated with rifaximin monotherapy, compared with only 14% of patients who received both rifaximin and lactulose.
Finally, in a phase II trial (abstract 2064), rifaximin immediate-release (40 mg) significantly outperformed placebo in terms of cirrhosis-related mortality, hospitalizations for cirrhosis, and breakthrough hepatic encephalopathy. The takeaways? “Use albumin with lactulose for acute hepatic encephalopathy,” Dr. Sanyal said. “Rifaximin with lactulose is better than rifaximin alone for secondary prophylaxis, and rifaximin immediate-release may decrease the need for hospitalization and the first bout of hepatic encephalopathy.”
The Liver Meeting next convenes October 20-24, 2017, in Washington, D.C.
Dr. Sanyal disclosed ties to Genfit, NewCo, Akarna, Elsevier, UptoDate, Novartis, Pfizer, Lilly, Astra Zeneca, and a number of other companies.

AT THE LIVER MEETING 2016
HCV patients with early-stage hepatocellular carcinoma can achieve SVR
BOSTON – Among patients with hepatocellular carcinoma (HCC), rates of sustained viral response (SVR) to direct-acting regimens for hepatitis C virus were 79% for genotype 1, 69% for genotype 2, and 47% for genotype 3 infections, reported George N. Ioannou, MD.
“These rates are lower than in patients who do not have hepatocellular carcinoma [HCC], but are still remarkably high,” Dr. Ioannou said during an oral presentation at the annual meeting of the American Association for the Study of Liver Diseases. “Antiviral therapy should be considered in patients with early-stage hepatocellular carcinoma, ideally after adequate locoregional treatments.”
The study included Veterans Affairs Health Care System data on 17,487 recipients of direct-acting anti-HCV regimens. When patients did not have HCC, SVR rates were 93% for genotype 1 infection, 87% for genotype 2 (GT2), and 76% for GT3. Among the 624 (3.6%) patients with a history of HCC, 142 underwent antiviral treatment after transplantation and 482 received other types of cancer therapy.
Why HCC is associated with lower SVR in HCV patients remains unclear, Dr. Ioannou noted. Age does not seem to explain the effect, and neither does sex, race, or ethnicity; cirrhosis or decompensated cirrhosis; renal disease; diabetes; HCV viral load; genotype or subgenotype; HCV regimen; or treatment experience, he said.
Dr. Ioannou noted several study limitations. Nine percent of patients lacked data on SVR, and the imputation to correct for this lowered SVR rates by about 1%-2%. The dataset also did not include information on HCC tumor size or number, and the researchers have not yet examined how antiviral therapy affects the likelihood of de novo HCC, recurrent HCC, or progression of cirrhosis and liver dysfunction.
The Veterans Affairs Office of Research and Development sponsored the study. Dr. Ioannou had no disclosures.

Tumor boards linked to improved survival in hepatocellular carcinoma
BOSTON – Veterans were about 13% less likely to die within 5 years of hepatocellular carcinoma diagnosis when multidisciplinary tumor boards managed their care than if they did not, according to a large, multicenter observational study.
Seeing a hepatologist or surgeon within 30 days of diagnosis also significantly improved 5-year overall survival, even after controlling for age, race, Charlson-Deyo comorbidity index, Barcelona Clinic Liver Cancer (BCLC) stage, academic center and geographic region of care, and the distance patients lived from the nearest Veterans Affairs transplant center, Marina Serper, MD, reported at the annual meeting of the American Association for the Study of Liver Diseases. “More studies are needed to understand how to best use multidisciplinary tumor boards to improve the care of patients with hepatocellular carcinoma,” she said.
Outcomes data for hepatocellular carcinoma mostly come from clinical trials; transplant centers; and Surveillance, Epidemiology, and End Results-Medicare analyses, noted Dr. Serper of the University of Pennsylvania in Philadelphia.
For a better look at veterans, she and her associates combined administrative, laboratory, and death data with medical chart reviews and information from the Organ Procurement and Transplantation Network’s Standard Transplant Analysis and Research file. The initial cohort included more than 6,800 veterans whose ICD-9CM diagnosis code indicated a malignant hepatic neoplasm. Excluding patients with neoplasms such as cholangiocarcinoma and those managed outside the VA left 3,989 VA patients with hepatocellular carcinoma.
In the multivariable analysis, use of multidisciplinary tumor boards was associated with a statistically significant 13% improvement in 5-year overall survival (hazard ratio, 0.87; 95% confidence interval, 0.81-0.94; P less than .001). Improved survival also was linked with seeing certain specialists within 30 days of diagnosis, including hepatologists (HR, 0.77; P less than .001) and surgeons (HR, 0.72; P less than .001). Consulting with a hepatologist within 30 days of diagnosis, however, did not improve the chances of receiving curative therapy, such as liver transplantation, resection, local ablation, transarterial chemoembolization, or Y-90 radioembolization.
Care also varied substantially geographically and by academic affiliation, Dr. Serper noted. “Treatment of hepatocellular carcinoma is complex, as it depends as much on liver function as it does on tumor staging,” she emphasized. “Studies to improve multidisciplinary approaches for hepatocellular carcinoma in the community are needed to increase rates of curative therapy and improve clinical outcomes.”
Patients in this study averaged 62 years of age at diagnosis, 54% were white, 36% were within Milan criteria, and 45% had a Child-Turcotte-Pugh score of B or higher. Nearly 18% had macrovascular invasion at diagnosis, and 7% had metastatic disease. Nearly two-thirds of patients were BCLC stage A or B at diagnosis, and more than a third had underlying alcohol misuse and chronic hepatitis C virus infection.
The work was funded by unrestricted grants from Bayer Healthcare Pharmaceuticals and the VA’s HIV, Hepatitis and Public Health Pathogens Programs. The investigators had no relevant financial disclosures.

Patients in this study averaged 62 years of age at diagnosis, 54% were white, 36% were within Milan criteria, and 45% had a Child-Turcotte-Pugh score of B or higher. Nearly 18% had macrovascular invasion at diagnosis, and 7% had metastatic disease. Nearly two-thirds of patients were BCLC stage A or B at diagnosis, and more than a third had underlying alcohol misuse and chronic hepatitis C virus infection.
The work was funded by unrestricted grants from Bayer Healthcare Pharmaceuticals and the VA’s HIV, Hepatitis and Public Health Pathogens Programs. The investigators had no relevant financial disclosures.
BOSTON – Veterans were about 13% less likely to die within 5 years of hepatocellular carcinoma diagnosis when multidisciplinary tumor boards managed their care than if they did not, according to a large, multicenter observational study.
Seeing a hepatologist or surgeon within 30 days of diagnosis also significantly improved 5-year overall survival, even after controlling for age, race, Charlson-Deyo comorbidity index, Barcelona Clinic Liver Cancer (BCLC) stage, academic center and geographic region of care, and the distance patients lived from the nearest Veterans Affairs transplant center, Marina Serper, MD, reported at the annual meeting of the American Association for the Study of Liver Diseases. “More studies are needed to understand how to best use multidisciplinary tumor boards to improve the care of patients with hepatocellular carcinoma,” she said.
Outcomes data for hepatocellular carcinoma mostly come from clinical trials; transplant centers; and Surveillance, Epidemiology, and End Results-Medicare analyses, noted Dr. Serper of the University of Pennsylvania in Philadelphia.
For a better look at veterans, she and her associates combined administrative, laboratory, and death data with medical chart reviews and information from the Organ Procurement and Transplantation Network’s Standard Transplant Analysis and Research file. The initial cohort included more than 6,800 veterans whose ICD-9CM diagnosis code indicated a malignant hepatic neoplasm. Excluding patients with neoplasms such as cholangiocarcinoma and those managed outside the VA left 3,989 VA patients with hepatocellular carcinoma.
In the multivariable analysis, use of multidisciplinary tumor boards was associated with a statistically significant 13% improvement in 5-year overall survival (hazard ratio, 0.87; 95% confidence interval, 0.81-0.94; P less than .001). Improved survival also was linked with seeing certain specialists within 30 days of diagnosis, including hepatologists (HR, 0.77; P less than .001) and surgeons (HR, 0.72; P less than .001). Consulting with a hepatologist within 30 days of diagnosis, however, did not improve the chances of receiving curative therapy, such as liver transplantation, resection, local ablation, transarterial chemoembolization, or Y-90 radioembolization.

VIDEO: PBC patients with compensated cirrhosis fare well on obeticholic acid
BOSTON – Patients with primary biliary cholangitis (PBC) who have compensated cirrhosis fared just as well on obeticholic acid (OCA) as did PBC patients without cirrhosis, according to an analysis of data from POISE, the pivotal clinical trial for approval of OCA for PBC.
The POISE trial included 36 individuals with PBC and compensated cirrhosis, since cirrhosis “is an endpoint for virtually all liver diseases,” John Vierling, MD, said in a video interview at the meeting.

To see how this group fared, Dr. Vierling and his coinvestigators performed a post hoc analysis of the POISE data to examine OCA’s safety and efficacy for patients with compensated cirrhosis. Patients with decompensated cirrhosis were not included in the trial.
Dr. Vierling, chief of hepatology at Baylor College of Medicine, Houston, noted that investigators worked hard to set the bar high for inclusion in the group with cirrhosis, to achieve very high specificity. “We did this by using very stringent criteria of liver biopsy, or transient elastography adjusted for a very high range of kilopascals required to diagnose cirrhosis in cholestatic patients,” he said. To be included, patients also had to have elevated total bilirubin levels and a baseline alkaline phosphatase level greater than five times the upper limit of normal.
Statistically, the patients were evenly distributed across the placebo arm and the two treatment arms, one of which dosed OCA at 10 mg/day; the other treatment arm had flexible dosing at 5-10 mg/day.
The POISE trial used a composite primary efficacy endpoint of achieving an alkaline phosphatase (ALP) less than 1.67 times the upper limit of normal, with total bilirubin within normal limits, and at least a 15% reduction in ALP.
“Significantly more OCA-treated patients with cirrhosis achieved the primary composite endpoint compared to placebo,” Dr. Vierling and his coauthors wrote in a poster presented at the annual meeting for the American Association for the Study of Liver Diseases. The difference was individually significant for all three values that made up the composite primary endpoint as well.
Secondary endpoints included gamma-glutamyltransferase, alanine aminotrasferase, and aspartate aminotransferase, all of which were significantly reduced among patients taking OCA. Patients on placebo saw these values rise over the time period of the study.
There were no new safety signals seen in the post hoc analysis of the group with cirrhosis that were not seen in the trial at large, said Dr. Vierling. Two individuals in the subgroup dropped out of the trial because of pruritis, a similar proportion to that seen in the full trial population.
The drug’s manufacturer, Intercept Pharmaceuticals, is working with the Food and Drug Administration to establish appropriate doses and intervals for obeticholic acid so it may be used safely in individuals with decompensated cirrhosis, said Dr. Vierling.
Obeticholic acid, a farnesoid-X receptor agonist, is an approved agent to use as add-on therapy to ursodeoxycholic acid (UDCA), or as monotherapy for patients who can’t tolerate UDCA.
Dr. Vierling disclosed financial relationships with Intercept Pharmaceuticals and with several other pharmaceutical companies. The study was funded by Intercept Pharmaceuticals.

EXPERT ANALYSIS FROM THE LIVER MEETING
SNP predicts liver cancer in hepatitis C patients regardless of SVR
BOSTON – rs4836493, a single nucleotide polymorphism of the gene encoding chondroitin sulfate synthase-3, significantly predicted hepatocellular carcinoma among patients with HCV even when they achieved sustained virologic response on pegylated interferon, according to a genome-wide association study.
The next step is to determine whether rs4836493 predicts liver cancer after SVR on the new direct-acting antiviral regimens, Basile Njei, MD, MPH, said during an oral presentation at the annual meeting of the American Association for the Study of Liver Diseases.
Cirrhotic patients face about a 2%-7% annual risk of hepatocellular carcinoma, noted Dr. Njei of Yale University, New Haven, Conn. “Recent studies show that people with HCV may still develop hepatocellular carcinoma even after achieving SVR,” he said.
To look for genetic predictors of this outcome, he and his associates genotyped 958 patients with HCV and advanced hepatic fibrosis from the Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) study. This trial had evaluated long-term, low-dose pegylated interferon therapy (90 mcg per week for 3.5 years) as a means of keeping fibrosis from progressing among HCV patients who had failed peginterferon and ribavirin therapy.
A total of 63% of patients had cirrhosis, and 55 (5.7%) developed biopsy or imaging-confirmed hepatocellular carcinoma over a median of 80 months of follow-up, Dr. Njei said. After the researchers controlled for age, sex, Ishak fibrosis score, and SVR status, rs4836493 predicted hepatocellular carcinoma with a highly significant P value of .000004.
This SNP is located on the CHSY3 gene, which plays a role in the chondroitin polymerization, tissue development, and morphogenesis, according to Dr. Njei. Notably, the gene has been implicated in the biology of colorectal tumors, he added.
Dr. Njei and his associates genotyped patients by using the 610-Quad platform, which contains more than 600,000 SNPs. They double-checked results and conducted more genetic analyses using PLINK 1.9, a free, open-source software program for genome-wide association data. Three-quarters of patients in the study were white, 72% were male, and median age at enrollment was 50 years, he noted.
Linking a single SNP to liver cancer despite SVR is a striking finding, but it is also preliminary, Dr. Njei cautioned. “The SNP identified in our discovery genome-wide association study needs future replication and validation in patients who achieve SVR after receiving the new direct-acting antiviral therapies,” he said.
The National Institutes of Health provided partial funding. Dr. Njei and his coinvestigators had no relevant financial conflicts of interest.

Treatment withdrawal without prior liver biopsy found safe in well-controlled autoimmune hepatitis
BOSTON – Although current guidance calls for a liver biopsy prior to treatment withdrawal in autoimmune hepatitis (AIH), a retrospective observational analysis conducted by researchers from the Cleveland Clinic offers a different view.
“Maybe not everyone needs a liver biopsy before withdrawing treatment,” Yilien Alonso, MD, an internist at the Cleveland Clinic in Weston, Fla., said in an interview at the annual meeting of the American Association for the Study of Liver Diseases.
Both the European Association for Study of the Liver and the AASLD recommend liver biopsy prior to treatment withdrawal in AIH, but the expensive procedure is not without risk of morbidity and mortality. Dr. Alonso and her coinvestigators reviewed the records of 508 AIH patients seen at their institution between January 2001 and April 2015. After excluding the records of patients who’d had juvenile onset of AIH, or who were treated with agents other than corticosteroids and azathioprine, the researchers found 34 adults with similar pretreatment profiles who’d had treatment withdrawal after 2 years of excellent response to treatment, 10 of whom had a liver biopsy prior to treatment withdrawal.
The outcomes at 1 year post treatment withdrawal for all 34 were similar, with no difference in flare rates or reinitiation of treatment. In those who’d had the second liver biopsy, the fibrosis stage was noted at 1 year to have declined in three patients.
“If you have a stable patient population that you are tracking every 3-6 months, we don’t see why you can’t stop the treatment without having to have another invasive procedure,” Dr. Alonso said.

VIDEO: Don’t be surprised by weight gain in men after HCV cure
BOSTON – In the new era of direct-acting antiviral (DAA) therapy, physicians will be seeing more and more patients who have achieved a cure of their hepatitis C virus (HCV). Once freed from the burden of a chronic illness, patients feel better and may eat better. Unexpected weight gain and potential associated health effects may be the next set of challenges patients and their physicians will face.
A single-center retrospective study of patients who had achieved sustained virologic response (SVR) after treatment for HCV found a small but significant weight gain in men, but not women. Additionally, according to noninvasive assessments, liver fat increased significantly in men, but not women, after SVR was achieved.
In a study of 63 patients (42 male, 67%) who received DAA treatment for HCV, mean weight gain for men after SVR was 2.8 pounds (range, –26 to +17; P = .0459), and body mass index (BMI) increased by a mean 0.50 kg/m2 (range, –3.6 to +3.33; P = .0176). No significant change was seen for women when pre- and posttreatment measures were compared.
Isaac Wasserman, a medical student at Mount Sinai Medical Center, New York, presented the results of the single-center retrospective study in a poster presentation at the annual meeting of the American Association for the Study of Liver Diseases.
To assess changes in liver fat, Mr. Wasserman and his coinvestigator used results of pre- and posttreatment transient elastography with controlled attenuation parameter (CAP). CAP measures the degree to which the ultrasound signal is attenuated by liver fat, he explained in a video interview.
For men, hepatic steatosis increased by this measure, with CAP measurements up by a mean 18 dB/m (range, –106 to +128, P = .0314). Mr. Wasserman and his colleagues wrote, “The change in liver fat was large enough to push 11% of the cohort (n = 7 of 63) into advanced steatosis (CAP greater than 300 dB/m).” Again, the women studied had no significant posttreatment change in liver fat.
Post-SVR weight gain appeared to be the culprit in the increased fat seen in the posttreatment livers. Mr. Wasserman and his colleagues in the abstract accompanying the presentation, “Changes in weight were positively correlated with changes in liver fat (P = .006).”
Mr. Wasserman said that he and his coinvestigators believe that social, and not biochemical or mechanistic, reasons underlie the weight gain and increased hepatic steatosis. They are planning further investigation of social and economic factors that may underlie the difference seen in this study, and hope to continue and expand data acquisition to validate their findings.
Mr. Wasserman reported no conflicts of interest or outside sources of funding for the study.

In a study of 63 patients (42 male, 67%) who received DAA treatment for HCV, mean weight gain for men after SVR was 2.8 pounds (range, –26 to +17; P = .0459), and body mass index (BMI) increased by a mean 0.50 kg/m2 (range, –3.6 to +3.33; P = .0176). No significant change was seen for women when pre- and posttreatment measures were compared.
Isaac Wasserman, a medical student at Mount Sinai Medical Center, New York, presented the results of the single-center retrospective study in a poster presentation at the annual meeting of the American Association for the Study of Liver Diseases.
To assess changes in liver fat, Mr. Wasserman and his coinvestigator used results of pre- and posttreatment transient elastography with controlled attenuation parameter (CAP). CAP measures the degree to which the ultrasound signal is attenuated by liver fat, he explained in a video interview.
For men, hepatic steatosis increased by this measure, with CAP measurements up by a mean 18 dB/m (range, –106 to +128, P = .0314). Mr. Wasserman and his colleagues wrote, “The change in liver fat was large enough to push 11% of the cohort (n = 7 of 63) into advanced steatosis (CAP greater than 300 dB/m).” Again, the women studied had no significant posttreatment change in liver fat.
Post-SVR weight gain appeared to be the culprit in the increased fat seen in the posttreatment livers. Mr. Wasserman and his colleagues in the abstract accompanying the presentation, “Changes in weight were positively correlated with changes in liver fat (P = .006).”
Mr. Wasserman said that he and his coinvestigators believe that social, and not biochemical or mechanistic, reasons underlie the weight gain and increased hepatic steatosis. They are planning further investigation of social and economic factors that may underlie the difference seen in this study, and hope to continue and expand data acquisition to validate their findings.
Mr. Wasserman reported no conflicts of interest or outside sources of funding for the study.
