Among patients with hepatitis B virus (HBV) infection who are not receiving antiviral therapy, surface antigen titers and alanine aminotransferase (ALT) levels may independently predict spontaneous seroconversion, based on a recent case-control study.

Patients with hepatitis B surface antigen (HBsAg) titers less than 1,000 IU/mL were significantly more likely to spontaneously seroconvert, reported principal author Sammy Saab, MD, of the University of California, Los Angeles, and colleagues.

While the predictive value of HBsAg titers has been demonstrated for patients undergoing antiviral therapy, data are limited for spontaneous seroconversion, the investigators wrote in Journal of Clinical Gastroenterology.

To learn more about this scenario, the investigators reviewed medical records from 2,126 patients who visited a large community practice in the Los Angeles area between 2014 and 2019. Cases were defined by HBV infection with seroconversion, whereas matched controls were defined by HBV without seroconversion. A variety of demographic and clinical data were also evaluated, including age, ethnicity, sex, HBsAg titer, ALT, HBV DNA, total cholesterol, presence of fatty liver, and other factors.

The investigators identified 167 patients with HBV who were not on antiviral therapy. Of these, 14 underwent seroconversion, and were matched with 70 patients who did not seroconvert. All patients were of Asian descent, most were women, and none had cirrhosis.

Across all demographic and clinical parameters, the two factors that significantly differed between cases and controls were ALT and HBsAg titer. The mean ALT for patients who seroconverted was 17.6 U/L, versus 25.1 U/L in those who did not undergo seroconversion (P less than .01). Similarly, mean titer was lower in the seroconversion group (459.8 vs. 782.0 IU/mL; P = .01).

The investigators noted that seroconversion was more common among patients with an HBsAg titer level less than 1,000 IU/mL. Specifically, 79% of patients who seroconverted had a titer less than 1,000 IU/mL, compared with just 16% of patients who did not seroconvert (P = .001).

HBV DNA levels were not predictive of seroconversion, the investigators noted, which aligns with most, but not all, previous research.

The investigators reported no disclosures.

For patients with nonalcoholic steatohepatitis (NASH), the GALAD score may accurately predict hepatocellular carcinoma (HCC) as early as 560 days before diagnosis, according to investigators.

The GALAD score, which combines sex, age, alpha-fetoprotein-L3 (AFP-L3), alpha-fetoprotein, and des-gamma-carboxyprothrombin (DCP), could improve cancer surveillance among NASH patients whose obesity limits sensitivity of ultrasound, reported lead author Jan Best, MD, of the University Hospital Magdeburg in Germany, and colleagues.

“The limitations of ultrasound surveillance alone for early detection of HCC are particularly evident in patients with NASH,” the investigators wrote in Clinical Gastroenterology and Hepatology. “Serum-based biomarkers might be more effective, with or without ultrasound surveillance, for HCC surveillance in NASH patients, although data in this patient population are currently lacking. The current study assessed the performance of the GALAD score for early HCC detection in patients with NASH-related liver disease.”

The study consisted of two parts: first, a retrospective case-control analysis, and second, a phase 3 prospective trial that implemented the GALAD score in a real-world population.

The retrospective component of the study involved 126 NASH patients with HCC (cases) and 231 NASH patients without HCC (controls), all of whom were treated at eight centers in Germany. The median GALAD score was significantly higher among NASH patients with HCC than in those without (2.93 vs. –3.96; P less than .001). At an optimal cutoff of –1.334, the GALAD score predicted HCC with a sensitivity of 91.2% and a specificity of 95.2%. Each component of the GALAD score aligned with previously published findings, as patients with HCC were predominantly older men with elevated serum AFP-L3, AFP, and DCP. But a closer look at the data showed that the GALAD score more accurately predicted HCC than any of its constituent serum measurements in isolation. For any stage of HCC, GALAD had an area under the curve (AUC) of 0.96, compared with significantly lower values for AFP (0.88), AFP-L3 (0.86), and DCP (0.87). Similarly, for early-stage HCC, GALAD score AUC was 0.92, compared with significantly lower values for AFP (0.77), AFP-L3 (0.74), and DCP (0.87).

The accuracy of the GALAD score – for detection of both any-stage and early-stage HCC — remained high regardless of cirrhosis status. Among patients with cirrhosis, the AUC for any-stage HCC was 0.93, and 0.85 for early-stage HCC. For patients without cirrhosis, GALAD was slightly more predictive, based on AUC’s of 0.98 and 0.94 for detection of any-stage and early-stage HCC, respectively. Again, these accuracy values significantly outmatched each serum measurement in isolation.

“These data on NASH-HCC patients demonstrate that GALAD can detect HCC independent of cirrhosis or stage of HCC,” the investigators wrote. “Indeed, even early noncirrhotic NASH-HCC seems clearly separable from NASH controls, as even small groups resulted in robust performance.”

The prospective component of the study involved screening 392 patients with NASH at a single treatment center in Japan. From this cohort, 28 patients developed HCC after a median of 10.1 years. Many patients in this group had significantly higher GALAD scores for 5 or more years before being diagnosed with HCC, and scores rose sharply in the months preceding diagnosis. Depending on selected cutoff value, the GALAD score predicted HCC from 200 to 560 days prior to diagnosis.

“While this specific result has to be confirmed in further prospective studies, it is a promising observation for potential use of GALAD as a screening tool in NASH patients,” the investigators wrote.

“In conclusion, our data confirm that the GALAD score is superior to individual serum markers for detection of HCC in NASH, independent of tumor stage or cirrhosis,” the investigators wrote. “The findings suggest that GALAD should be investigated as a potential tool for screening of NASH individuals to detect HCC at a resectable stage in a sufficiently large prospective study to identify a cutoff.”

The study was funded by Deutsche Forschungsgemeinschaft, the Wilhelm-Laupitz Foundation, and the Werner Jackstaedt Foundation. The investigators declared no conflicts of interest.

LOS ANGELES – The way Christos S. Mantzoros, MD, DSc, PhD, sees it, nonalcoholic steatohepatitis (NASH) is an epidemic of the 21st century that can trigger a cascade of reactions.

Doug Brunk/MDedge News

“If more than 5.8% of fat is in the liver, we call it nonalcoholic fatty liver disease [NAFLD],” Dr. Mantzoros, professor of medicine at Harvard Medical School, Boston, and Boston University, explained at the World Congress on Insulin Resistance, Diabetes, and Cardiovascular Disease. “If inflammation develops to remove the fat, we call it NASH. If this progresses to decompensated reaction and fibrosis and cirrhosis, then we call it nonalcoholic steatohepatitis with fibrosis. That can lead to liver cirrhosis, hepatocellular carcinoma, and liver failure.”

The underlying problem stems from the rise in obesity prevalence, according to Dr. Mantzoros, who is also chief of endocrinology at the Boston Veterans Affairs Healthcare System. For 75%-80% of individuals with metabolically unhealthy obesity, the storage space in their adipose tissue is exceeded. “Fat is deposited into muscle, causing insulin resistance, and into the liver,” he explained. “If it’s more than 5.8%, it causes NAFLD. Most of us don’t realize that most of the patients with diabetes we have in our clinics also have nonalcoholic fatty liver disease. That’s because we don’t have an easy diagnostic tool or an easy treatment. It’s an unmet clinical need.” (There are currently no drugs approved for the treatment of NASH or NAFLD. Current recommended first-line treatment is weight loss through diet and exercise and control of diabetes, if it is present.)

“Assuming the rate of increase in cost due to NAFLD parallels the growth in obesity, the 10-year projection for direct cost is $1.005 trillion,” said Dr. Mantzoros, who is also editor in chief of the journal Metabolism. “Obesity, NAFLD, and insulin resistance are each independently associated with a twofold risk for diabetes. If all three are present, there is a 14-fold risk for diabetes. Insulin resistance promotes an increase in free fatty acid traffic to the liver, which can trigger hepatic lipotoxicity. Hyperinsulinemia enhances free fatty acid uptake and activates de novo lipogenesis. Hyperglycemia can also activate de novo lipogenesis.”

About 85 million Americans have NAFLD, he continued. Most (80%) are cases of steatosis, but 20% have NASH. Of those, 20% develop advanced fibrosis, which leads to liver failure and transplantation or death. A study of data from the National Health and Nutrition Examination Survey found that diabetes was the strongest predictor of advanced fibrosis in patients with NAFLD (odds ratio, 18.20), followed by a body mass index of 30 kg/m² or greater (OR, 9.10), hypertension (OR, 1.20), and age (OR, 1.08; Ailment Pharmacol Ther. 2017;46:974-80). “Most of the patients who come to our clinics with diabetes have nonalcoholic fatty liver disease – 75%-80% in our clinics, and about 10% have advanced fibrosis,” Dr. Mantzoros said. “Most of them go undiagnosed.”

Patients with type 2 diabetes and NAFLD progress faster to fibrosis and end-stage liver disease, compared with those who do not have diabetes. One study of 108 patients with biopsy-proven NALFD showed that 84% of those with fibrosis progression had type 2 diabetes (J Hepatol. 2015;62:1148-55). Other findings have shown that patients with type 2 diabetes are at increased risk of chronic NAFLD and hepatocellular carcinoma (Gastroenterol. 2001;126:460-8). “We are doing more liver transplantations because of NAFLD and NASH than because of hepatitis C,” Dr. Mantzoros said. “What we need to keep in mind is that, although liver morbidity and mortality is important, this is a component of the cardiometabolic syndrome. So, people have all the risk factors for cardiovascular disease. Because CVD is much more common, people with NAFLD suffer from and die from CVD. The more advanced the NAFLD, the higher the risk of death from cardiovascular disease.”

Multiple risk factors can help identify patients with advanced fibrosis because of NASH, he continued, including having features of the metabolic syndrome, being over 50 years of age, being Hispanic, having high levels of ALT/AST, low platelets, and having low albumin. “These are frequent tests that we can find in the EMR,” Dr. Mantzoros said. “The problem with ALT is that, in many stages of the disease, ALT goes up. But after a certain stage of the disease, when most of the liver is controlled by fibrosis and cirrhosis, most of the hepatocytes are dead and don’t secrete ALT, so ALT in end-stage renal disease goes up.”

Recent guidelines recognize the association between diabetes, NAFLD, and NASH, and call for increased vigilance and screening tests. According to guidelines from the American Association for the Study of Liver Diseases, the Fibrosis-4 Index or the NAFLD Fibrosis Score are clinically useful tools for identifying NAFLD in patients with higher likelihood of having bridging fibrosis or cirrhosis (Hepatology. 2018;67[1]:328-57). Vibration-controlled transient elastography or MRI are clinically useful tools for identifying advanced fibrosis in patients with NAFLD, whereas clinical decision aids, such as Fibrosis-4, NAFLD Fibrosis Score, or vibration-controlled transient elastography, can be used to identify patients at low or high risk for advanced fibrosis.

“If we have a patient with suspected NAFLD, we need to rule out alcohol use, we need to confirm NAFLD, and we need to risk stratify, and classify as low, intermediate, or high risk,” Dr. Mantzoros said. Most of his patients who meet criteria for high-risk NASH do not elect to undergo a liver biopsy. “I don’t blame them for that,” he said. “There is a 0.1 per 1,000 mortality risk, even in the best hands. If 80 million people who have fatty liver were to undergo a liver biopsy, we would have 16,000 deaths every year just because of that. We would not tolerate that.”

Recently, Dr. Mantzoros and colleagues published a proof-of-concept study that proposes novel models using lipids, hormones, and glycans that can diagnose the presence of NASH, NAFLD, or healthy status with high accuracy (Metabolism. 2019 Nov 8. doi: 10.1016/j.metabol.2019.154005). “We are now working with companies to validate it and expand it, not only as a diagnostic marker, but as a prognostic marker, and to try to commercialize it in the future,” he said.

Current pharmacotherapies are limited to patients with biopsy-confirmed NASH and fibrosis. Pioglitazone is a first-line, off-label pharmacologic treatment, while vitamin E may be used in patients with biopsy-confirmed NASH without diabetes. Metformin, glucagonlike peptide–1 receptor agonists, and sodium-glucose transporter 2 inhibitors are either not recommended or have insufficient evidence to recommend their use. More than 60 phase 2 trials are planned or ongoing, Dr. Mantzoros added, with phase trials underway for cenicriviroc, elafibranor, obeticholic acid, and selonsertib.

The role of lifestyle management is also important. “The Mediterranean diet has the best evidence, along with exercise, to improve early stages of NAFLD,” he said. “Weight loss is very important. If the patient loses 10% of their weight or more, there is NASH resolution 90% of the time. With less weight loss, we have less resolution. The problem is that only 10% of patients or less can sustain a more than 90% weight loss over a year.”

Dr. Mantzoros reported being a shareholder of Coherus BioSciences and Pangea Therapeutics, having served as an adviser to Coherus, Novo Nordisk, and Genfit and having received research grants through his institution from Coherus, Eisai, and Novo Nordisk.

Most of his patients who meet criteria for high-risk NASH do not elect to undergo a liver biopsy. “I don’t blame them for that,” he said. “There is a 0.1 per 1,000 mortality risk, even in the best hands. If 80 million people who have fatty liver were to undergo a liver biopsy, we would have 16,000 deaths every year just because of that. We would not tolerate that.”

Recently, Dr. Mantzoros and colleagues published a proof-of-concept study that proposes novel models using lipids, hormones, and glycans that can diagnose the presence of NASH, NAFLD, or healthy status with high accuracy (Metabolism. 2019 Nov 8. doi: 10.1016/j.metabol.2019.154005). “We are now working with companies to validate it and expand it, not only as a diagnostic marker, but as a prognostic marker, and to try to commercialize it in the future,” he said.

Current pharmacotherapies are limited to patients with biopsy-confirmed NASH and fibrosis. Pioglitazone is a first-line, off-label pharmacologic treatment, while vitamin E may be used in patients with biopsy-confirmed NASH without diabetes. Metformin, glucagonlike peptide–1 receptor agonists, and sodium-glucose transporter 2 inhibitors are either not recommended or have insufficient evidence to recommend their use. More than 60 phase 2 trials are planned or ongoing, Dr. Mantzoros added, with phase trials underway for cenicriviroc, elafibranor, obeticholic acid, and selonsertib.

The role of lifestyle management is also important. “The Mediterranean diet has the best evidence, along with exercise, to improve early stages of NAFLD,” he said. “Weight loss is very important. If the patient loses 10% of their weight or more, there is NASH resolution 90% of the time. With less weight loss, we have less resolution. The problem is that only 10% of patients or less can sustain a more than 90% weight loss over a year.”

Dr. Mantzoros reported being a shareholder of Coherus BioSciences and Pangea Therapeutics, having served as an adviser to Coherus, Novo Nordisk, and Genfit and having received research grants through his institution from Coherus, Eisai, and Novo Nordisk.

LOS ANGELES – The way Christos S. Mantzoros, MD, DSc, PhD, sees it, nonalcoholic steatohepatitis (NASH) is an epidemic of the 21st century that can trigger a cascade of reactions.

Doug Brunk/MDedge News

“If more than 5.8% of fat is in the liver, we call it nonalcoholic fatty liver disease [NAFLD],” Dr. Mantzoros, professor of medicine at Harvard Medical School, Boston, and Boston University, explained at the World Congress on Insulin Resistance, Diabetes, and Cardiovascular Disease. “If inflammation develops to remove the fat, we call it NASH. If this progresses to decompensated reaction and fibrosis and cirrhosis, then we call it nonalcoholic steatohepatitis with fibrosis. That can lead to liver cirrhosis, hepatocellular carcinoma, and liver failure.”

The underlying problem stems from the rise in obesity prevalence, according to Dr. Mantzoros, who is also chief of endocrinology at the Boston Veterans Affairs Healthcare System. For 75%-80% of individuals with metabolically unhealthy obesity, the storage space in their adipose tissue is exceeded. “Fat is deposited into muscle, causing insulin resistance, and into the liver,” he explained. “If it’s more than 5.8%, it causes NAFLD. Most of us don’t realize that most of the patients with diabetes we have in our clinics also have nonalcoholic fatty liver disease. That’s because we don’t have an easy diagnostic tool or an easy treatment. It’s an unmet clinical need.” (There are currently no drugs approved for the treatment of NASH or NAFLD. Current recommended first-line treatment is weight loss through diet and exercise and control of diabetes, if it is present.)

“Assuming the rate of increase in cost due to NAFLD parallels the growth in obesity, the 10-year projection for direct cost is $1.005 trillion,” said Dr. Mantzoros, who is also editor in chief of the journal Metabolism. “Obesity, NAFLD, and insulin resistance are each independently associated with a twofold risk for diabetes. If all three are present, there is a 14-fold risk for diabetes. Insulin resistance promotes an increase in free fatty acid traffic to the liver, which can trigger hepatic lipotoxicity. Hyperinsulinemia enhances free fatty acid uptake and activates de novo lipogenesis. Hyperglycemia can also activate de novo lipogenesis.”

About 85 million Americans have NAFLD, he continued. Most (80%) are cases of steatosis, but 20% have NASH. Of those, 20% develop advanced fibrosis, which leads to liver failure and transplantation or death. A study of data from the National Health and Nutrition Examination Survey found that diabetes was the strongest predictor of advanced fibrosis in patients with NAFLD (odds ratio, 18.20), followed by a body mass index of 30 kg/m² or greater (OR, 9.10), hypertension (OR, 1.20), and age (OR, 1.08; Ailment Pharmacol Ther. 2017;46:974-80). “Most of the patients who come to our clinics with diabetes have nonalcoholic fatty liver disease – 75%-80% in our clinics, and about 10% have advanced fibrosis,” Dr. Mantzoros said. “Most of them go undiagnosed.”

Patients with type 2 diabetes and NAFLD progress faster to fibrosis and end-stage liver disease, compared with those who do not have diabetes. One study of 108 patients with biopsy-proven NALFD showed that 84% of those with fibrosis progression had type 2 diabetes (J Hepatol. 2015;62:1148-55). Other findings have shown that patients with type 2 diabetes are at increased risk of chronic NAFLD and hepatocellular carcinoma (Gastroenterol. 2001;126:460-8). “We are doing more liver transplantations because of NAFLD and NASH than because of hepatitis C,” Dr. Mantzoros said. “What we need to keep in mind is that, although liver morbidity and mortality is important, this is a component of the cardiometabolic syndrome. So, people have all the risk factors for cardiovascular disease. Because CVD is much more common, people with NAFLD suffer from and die from CVD. The more advanced the NAFLD, the higher the risk of death from cardiovascular disease.”

Multiple risk factors can help identify patients with advanced fibrosis because of NASH, he continued, including having features of the metabolic syndrome, being over 50 years of age, being Hispanic, having high levels of ALT/AST, low platelets, and having low albumin. “These are frequent tests that we can find in the EMR,” Dr. Mantzoros said. “The problem with ALT is that, in many stages of the disease, ALT goes up. But after a certain stage of the disease, when most of the liver is controlled by fibrosis and cirrhosis, most of the hepatocytes are dead and don’t secrete ALT, so ALT in end-stage renal disease goes up.”

Recent guidelines recognize the association between diabetes, NAFLD, and NASH, and call for increased vigilance and screening tests. According to guidelines from the American Association for the Study of Liver Diseases, the Fibrosis-4 Index or the NAFLD Fibrosis Score are clinically useful tools for identifying NAFLD in patients with higher likelihood of having bridging fibrosis or cirrhosis (Hepatology. 2018;67[1]:328-57). Vibration-controlled transient elastography or MRI are clinically useful tools for identifying advanced fibrosis in patients with NAFLD, whereas clinical decision aids, such as Fibrosis-4, NAFLD Fibrosis Score, or vibration-controlled transient elastography, can be used to identify patients at low or high risk for advanced fibrosis.

“If we have a patient with suspected NAFLD, we need to rule out alcohol use, we need to confirm NAFLD, and we need to risk stratify, and classify as low, intermediate, or high risk,” Dr. Mantzoros said.

Serum keratin 18, an epithelial protein released from dying hepatocytes, identifies patients with severe acute alcoholic hepatitis (AAH) at high risk for death, according to an investigation of 173 subjects.

Standard biomarker scores – Model for End-stage Liver Disease (MELD), age, serum bilirubin, International Normalized Ratio, and serum creatinine (ABIC), as well as others – predict prognosis and severity of alcoholic liver disease, but they don’t reflect “the magnitude of cell death nor the form of cell death (apoptosis/necrosis), which may be important in distinguishing various forms of liver injury” and guiding therapy, explained investigators led by Vatsalya Vatsalya, MD, of the division of gastroenterology, hepatology, and nutrition at the University of Louisville (Ky.).

It’s important, for instance, to identify people with alcoholic cirrhosis but not active hepatitis, as they “would likely not benefit from anti-inflammatory agents such as steroids or [interleukin]-1 receptor antagonists, but would incur their side effects.” For those and other reasons, “new biomarkers are needed for diagnosing AAH, assessing the degree of hepatocyte death, and predicting mortality,” they said (Clin Gastroenterol Hepatol. 2019 Dec 4. doi: 10.1016/j.cgh.2019.11.050).

Keratin 18 – both the cleaved form (K18M30) and the uncleaved protein (K18M65) – have been suggested before as a marker for AAH, so the investigators took a closer look.

They analyzed serum from 57 people with severe AAH (MELD score above 20), 27 people with moderate AAH (MELD score 12-19), 34 with nonalcoholic steatohepatitis, 17 healthy controls, and 38 people with alcohol use disorder and either mild or no liver injury.

Overall, 51.9% of moderate AAH cases and 38.9% of severe cases had K18M65 levels between 641 and 2,000 IU/L; 25.9% of moderate and 61.1% of severe cases had K18M65 levels greater than 2,000 IU/L. All severe cases had levels above 641 IU/L. Serum levels of K18 also identified patients who died within 90 days with greater accuracy than did MELD, ABIC, and other scores, the investigators said.

The K18M65:ALT [alanine aminotransferase] ratio distinguished AAH from nonalcoholic steatohepatitis with a sensitivity of 0.971 and specificity of 0.829. Findings were similar for the K18M30:ALT ratio.

Levels of K18M65 and K18M30 increased significantly as liver disease worsened, as did the degree of necrosis as indicated by the K18M65:K18M30 ratio. Meanwhile, although k18 levels correlated with MELD scores, levels of ALT, aspartate aminotransferase (AST), and the ratio of AST:ALT did not.

“There is a stronger association between serum level of keratin 18 and amount of hepatocyte death and liver disease severity than for other biomarkers,” the team concluded.

Patients were in their mid 40s, on average, and there were more men than women.

The National Institutes of Health supported the work, and the investigators had no disclosures.

The incorporation of telehealth in the liver transplantation process is demonstrating the potential to expedite the evaluation of patients and get them listed on the transplant wait list.

kgtoh/Thinkstock

New research shows “a transplant hepatologist evaluation using telehealth was associated with significantly reduced time to evaluation and listing without adversely affecting pretransplant mortality compared to the current standard of care of in-person evaluation at a transplant center,” Binu V. John, MD, of McGuire VA Medical Center, Richmond, and colleagues wrote in a report published in Clinical Gastroenterology and Hepatology (2019 Dec 27. doi: 10.1016/j.cgh.2019.12.021).

Researchers looked at 465 patients who had evaluations for liver transplants at the Richmond Veterans Affairs Medical Center from 2005 through 2017. Nearly half (232 patients) were evaluated via telehealth, with the remaining 233 evaluated with traditional in-person evaluations.

“Patients in the telehealth group were evaluated significantly faster than patients in the usual care group (22 vs. 54 days, P less than .001),” Dr. John and colleagues wrote, adding that, after conducting a propensity-matched analysis, “telehealth was associated with an 85% reduction in time from referral to evaluation.”

Additionally, patients “who underwent the initial evaluation by telehealth were listed significantly earlier than the usual care group (95 vs. 149 days; P less than .001),” the authors stated, adding that “telehealth was associated with a 74% reduction in time to listing” after conducting a propensity-matched analysis.

However, while speeding up time to referral and listing, “the median time to transplant was not significantly different between the two groups on unadjusted (218 vs. 244 days; P = .084) or adjusted analysis (325 vs. 409 days; P = .08),” they added.

Additionally, “there was no difference in pretransplant mortality between [those] evaluated by telehealth or usual care in unadjusted analysis,” Dr. John and colleagues observed, noting that 169 of 465 patients (51 on the waiting list for a transplant and 118 who were not listed) who were referred died without receiving a liver transplant.

Researchers suggested that while evaluation times may have been shorter with the use of telehealth, they did not translate to shorter transplantation times “likely because the latter is a complex metric that is driven primarily by organ availability.”

Dr. John and colleagues cautioned that the centralized nature of the VA medical system could make the results of this study not generalizable across private care settings, particularly when care needs to cross state lines, which does not present an issue within the VA medical system.

That being said, the “ability to successfully evaluate and list patients via telehealth and obtain the same outcomes in terms of time to transplant and pretransplant mortality is significant because of the numerous advantages that telehealth offers to improve overall access to transplantation,” they stated, adding that more studies are needed, both in and out of the VA system, “to confirm that telehealth is a safe and effective way to expand access for patients undergoing evaluation for liver transplantation.”

Patients with nonalcoholic fatty liver disease (NAFLD) in a prospective observational study had a twofold increase in cardiovascular events, NAFLD patients with liver fibrosis had a fourfold increase in risk, and liver fibrosis scores predicted risk.

At median follow-up of 41.4 months representing 3,044.4 person-years of observation in the Progression of Liver Damage and Cardiometabolic Disorders in NAFLD (PLINIO) study, 58 cardiovascular events (CVEs) were reported in 898 consecutive outpatients who were screened for liver steatosis by ultrasound. The annual rate of CVEs among 643 patients with NAFLD was 2.1%, compared with 1.0% among 255 patients without NAFLD, according to Francesco Baratta, MD, of Clinica Medica, Sapienza University of Rome, and colleagues. Their report is in Clinical Gastroenterology and Hepatology.

The difference did not meet a priori thresholds for statistical significance (P = .066), but became significant after exclusion of new-onset atrial fibrillation events (annual CVE rates of 1.9% vs. 0.7%; P = .034), and on multivariate analysis, age, male sex, and NAFLD were found to be independently associated with CVE occurrence (hazard ratios, 1.07, 3.20, and 2.73, respectively), the investigators found.

In NAFLD patients, a NAFLD fibrosis score (NFS) greater than 0.676 was significantly associated with CVEs after adjustment for comorbidities (HR, 2.29), and a Fibrosis-4 (FIB-4) score greater than 2.67, a history of cardiovascular disease, and metabolic syndrome predicted incident CVEs (HRs, 4.57, 2.95, and 2.30, respectively). The findings were similar after exclusion of new-onset atrial fibrillation from the composite endpoint (HRs, 2.42 and 4.00, respectively).

“Furthermore, when we analyzed only patients without CVEs at baseline, we found a similar association between liver fibrosis and CVEs,” the researchers wrote, noting that the adjusted HRs for NFS were 2.50 and 4.28, respectively.

In addition to liver-related complications, patients with NAFLD are known to have an increased CVE risk, and while liver fibrosis severity is used to determine prognosis, not all patients can undergo a liver biopsy to assess fibrosis. Therefore, there is a need to identify and validate noninvasive markers of liver fibrosis, but few data exist with respect to the predictive role of noninvasive scoring on CVEs, they said.

The findings of this study suggest the use of the NFS and FIB-4 score may reduce the need for liver biopsy by identifying NAFLD patients at higher risk of having advanced liver fibrosis. They further suggest that liver fibrosis development in patients with NAFLD “may be the result of a long-term exposure to cardiometabolic risk factors such as diabetes,” and that “the concomitant presence of multiple cardiometabolic conditions may induce a chronic low-grade proinflammatory and pro-oxidant status leading to liver inflammation (i.e., macrophage activation) and collagen deposition.”

The findings may also have clinical implications: “The association between liver fibrosis and cardiovascular risk supports a potential role for statin treatment in patients with NAFLD,” they explained.

At median follow-up of 41.4 months representing 3,044.4 person-years of observation in the Progression of Liver Damage and Cardiometabolic Disorders in NAFLD (PLINIO) study, 58 cardiovascular events (CVEs) were reported in 898 consecutive outpatients who were screened for liver steatosis by ultrasound. The annual rate of CVEs among 643 patients with NAFLD was 2.1%, compared with 1.0% among 255 patients without NAFLD, according to Francesco Baratta, MD, of Clinica Medica, Sapienza University of Rome, and colleagues. Their report is in Clinical Gastroenterology and Hepatology.

The difference did not meet a priori thresholds for statistical significance (P = .066), but became significant after exclusion of new-onset atrial fibrillation events (annual CVE rates of 1.9% vs. 0.7%; P = .034), and on multivariate analysis, age, male sex, and NAFLD were found to be independently associated with CVE occurrence (hazard ratios, 1.07, 3.20, and 2.73, respectively), the investigators found.

In NAFLD patients, a NAFLD fibrosis score (NFS) greater than 0.676 was significantly associated with CVEs after adjustment for comorbidities (HR, 2.29), and a Fibrosis-4 (FIB-4) score greater than 2.67, a history of cardiovascular disease, and metabolic syndrome predicted incident CVEs (HRs, 4.57, 2.95, and 2.30, respectively). The findings were similar after exclusion of new-onset atrial fibrillation from the composite endpoint (HRs, 2.42 and 4.00, respectively).

“Furthermore, when we analyzed only patients without CVEs at baseline, we found a similar association between liver fibrosis and CVEs,” the researchers wrote, noting that the adjusted HRs for NFS were 2.50 and 4.28, respectively.

In addition to liver-related complications, patients with NAFLD are known to have an increased CVE risk, and while liver fibrosis severity is used to determine prognosis, not all patients can undergo a liver biopsy to assess fibrosis. Therefore, there is a need to identify and validate noninvasive markers of liver fibrosis, but few data exist with respect to the predictive role of noninvasive scoring on CVEs, they said.

The findings of this study suggest the use of the NFS and FIB-4 score may reduce the need for liver biopsy by identifying NAFLD patients at higher risk of having advanced liver fibrosis. They further suggest that liver fibrosis development in patients with NAFLD “may be the result of a long-term exposure to cardiometabolic risk factors such as diabetes,” and that “the concomitant presence of multiple cardiometabolic conditions may induce a chronic low-grade proinflammatory and pro-oxidant status leading to liver inflammation (i.e., macrophage activation) and collagen deposition.”

The findings may also have clinical implications: “The association between liver fibrosis and cardiovascular risk supports a potential role for statin treatment in patients with NAFLD,” they explained.

For patients with chronic hepatitis B virus (HBV) infection, up to 10 years of treatment with entecavir was safe and produced a superior rate of sustained virologic response, compared with other HBV nucleoside or nucleotide analogues in a global randomized clinical trial.

Virologic responses were confirmed and maintained in 80% of entecavir patients and 61% of patients who received other therapies, said Jin-Lin Hou, MD, of Southern Medical University in Guangzhou, China, and associates. Regardless of which treatment patients received, a sustained virologic response was associated with a significantly lower rate of liver-related hepatitis B virus (HBV) disease progression and hepatocellular carcinoma. Rates of serious treatment-related adverse events were 0.2% in the entecavir arm and 0.8% in the nonentecavir arm. Moreover, the primary outcome of time-to-adjudicated clinical outcome events “showed that entecavir treatment, compared with nonentecavir, was not associated with an increased risk of malignant neoplasms, including hepatocellular carcinoma, nonhepatocellular carcinoma malignancies, and overall malignancies,” they wrote in Clinical Gastroenterology and Hepatology.

Entecavir is approved for the treatment of adults with chronic HBV infection, and its long-term use has been linked to the regression of hepatic fibrosis and cirrhosis. In treatment-naive patients, genotypic resistance and virologic breakthrough are rare even after up to 5 years of entecavir therapy. Although human studies have not linked this treatment duration with an increased risk of adverse events, murine studies have identified benign and malignant tumors of the brain, lung, and liver in entecavir-treated mice and rats. “With the exception of lung tumors, which were limited to male mice, rodent tumors occurred only at entecavir exposures [that were] significantly higher than those achieved in human beings with standard approved doses,” the researchers wrote.

For the trial, they assigned more than 12,000 patients with chronic HBV infection to receive long-term treatment with entecavir or investigators’ choice of another HBV nucleoside or nucleotide analogue. Patients were from 229 centers in Asia, Europe, and North and South America, and a total of 6,216 received entecavir, while 6,162 received another therapy.

Compared with other HBV nucleoside and nucleotide analogues, long-term treatment with entecavir “provided a high margin of safety” and was not tied to higher rates of liver or nonliver malignancies, the researchers found. The carcinogenicity of entecavir in rodents did not appear to extend to humans. Furthermore, among 5,305 trial participants in China, a sustained virologic response was associated with a clinically and statistically significant reduction in the risk of liver-related HBV disease progression (hazard ratio, 0.09; 95% CI, 0.04-0.22) and hepatocellular carcinoma (HR, 0.03; 95% CI, 0.009-0.113).

The results confirm the appropriateness of long-term entecavir therapy for chronic HBV infection, as recommended by current guidelines, Dr. Hou and associates concluded. However, patients in this trial were relatively young, with a median age of only 39 years. Therefore, the risk of entecavir-associated malignancies in older age cohorts could not be evaluated.

Bristol-Myers Squibb designed the study, performed statistical analyses, and funded the study and manuscript preparation. The Ministry of Science and Technology of China and the Local Innovative and Research Teams Project of Guangdong Pearl River Talents Program provided partial support. Dr. Hou disclosed grants and personal fees from Bristol-Myers Squibb, GlaxoSmithKline, and Novartis. Several coinvestigators also disclosed ties to Bristol-Myers Squibb and to several other pharmaceutical companies.

Currently available fibrosis scoring systems appear to have only a modest predictive ability for development of severe liver disease in the general population, according to authors of a large, retrospective cohort study.

Of five noninvasive scoring systems evaluated, all did have high negative predictive value in the general population, according to authors of the study, which included data on more than 800,000 individuals in Sweden. However, their sensitivities were low, with most of the individuals who developed severe liver disease over a 10-year follow-up period initially classified as being at low risk for advanced fibrosis, according to the study authors, led by Hannes Hagström, MD, PhD, of the division of hepatology, Karolinska University Hospital, Stockholm.

The scoring systems tended to perform better in patients at higher risk for nonalcoholic fatty liver disease (NAFLD) at baseline, suggesting the best use of the tools is in patients at increased risk or who have liver disease indications, Dr. Hagström and coauthors wrote in a report on the study.

“Although useful in populations with a high prevalence of advanced fibrosis, current scores lack precision for usage in the general population for which the prevalence of advanced fibrosis is much lower,” Dr. Hagström and colleagues said.

The scoring systems were derived from high-risk cohorts with liver diseases, the authors noted, stating that the disease prevalence in any given population will affect the performance of a test that’s intended to diagnose that specific disease.

“New and improved” scoring systems should be developed to more effectively pinpoint patients with NAFLD who are at higher risk of a severe liver event, they added in the report, which appears in Gastroenterology.

The population-based cohort study by Dr. Hagström and colleagues was based on data from 812,073 patients enrolled in the Swedish Apolipoprotein Mortality Risk (AMORIS) cohort between 1985 and 1996. Investigators said they excluded patients under 35 and over 79 years of age, patients with severe liver disease at baseline, and those with a prior diagnosis of alcohol or drug abuse.

Investigators used available data to calculate five scores, including the AST to Platelet Ratio Index (APRI); the body mass index, AST/ALT ratio, and diabetes (BARD) score; the Fibrosis-4 (FIB-4) score; Forns Index; and NAFLD Fibrosis Score (NFS).

At baseline, 0.5%-8.0% of patients were considered to be at high risk for advanced fibrosis, depending on the test used, investigators said. With up to 10 years of follow-up, the proportion of individuals who developed severe liver diseases (cirrhosis, liver failure, hepatocellular carcinoma, liver transplantation, or decompensated liver disease) was 0.3%-0.6%, and with the maximum 27 years of follow-up, the incidence ranged from 1.0% to 1.4%.

There was a “strong association” between baseline risk of fibrosis and development of severe liver diseases; however, the majority of cases occurred in patients deemed low risk at baseline, Dr. Hagström and colleagues noted in their report.

For example, 12.4% of individuals classified as high risk by APRI developed severe liver diseases over 10 years, compared to just 0.4% of the low-risk group, yet out of 723 cases, 502 (69%) occurred in the low-risk patients, the data show.

Hazard ratios did increase with risk level, and at the high-risk level, adjusted hazard ratios ranged from 1.7 (95% confidence interval [CI], 1.1-2.5) for the high-risk BARD patients to 45.9 (95% CI, 36.1-58.3) for the high-risk APRI patients, investigators reported.

Taken together, results of this study demonstrate that the performance of all scores was low in an unselected population, according to investigators.

Of all tests, APRI was least likely to falsely classify patients who never developed severe liver diseases and had an intermediate-risk group of 4%, the lowest of any test, which are findings that may have implications for routine primary care, according to investigators.

“APRI could be the currently best score to exclude a high risk of liver-related events in the near future, and thereby reduce unnecessary testing in a general population,” they said in a discussion of their results.

The study was supported by an independent grant from AstraZeneca. Dr. Hagström reported disclosures related to that company, as well as Novo Nordisk, Gilead Sciences, IQVIA, Intercept, and Bristol Myers-Squibb.

BARCELONA – The investigational oral agent cenicriviroc showed positive effects on liver fibrosis in adults with nonalcoholic steatohepatitis (NASH), many of whom had type 2 diabetes, in a phase 2b trial reported at the annual meeting of the European Association for the Study of Diabetes.

Other data released at the meeting, which showed potential positive effects of novel or existing diabetes treatments on nonalcoholic fatty liver disease (NAFLD), included post hoc analyses of a phase 2b study with tirzepatide and a phase 3 study that combined exenatide and dapagliflozin.

Currently, no medications for NAFLD or NASH have been approved in the United States.

CENTAUR with cenicriviroc

Results of the previously reported CENTAUR trial showed that the antifibrotic effects of cenicriviroc, a dual chemokine receptor antagonist, were greatest in patients with more-severe liver disease (Hepatology. 2018;67[5]:1754-67). At the meeting, Henrik Landgren, PhD, of Allergan, presented data from the 2-year trial overall, and specifically in patients with advanced, stage 3 fibrosis.

CENTAUR was a randomized, double-blind, placebo-controlled, multinational study with 289 adults who had biopsy-confirmed NASH, an NAFLD Activity Score (NAS; range, 0-8; score of 5 or more diagnostic of NASH) of 4 or more, and stages 1-3 liver fibrosis as determined by the NASH clinical research network system (Contemp Clin Trials. 2016;47:356-65). The mean age of the patients enrolled at baseline was 54 years, the mean body mass index was 33.9 kg/m², and just more than half the patients (52%) had type 2 diabetes.

The patients were randomized to three treatment arms: cenicriviroc 150 mg for 2 years; placebo for 1 year, then cenicriviroc 150 mg for 1 year; or placebo for 2 years. The primary endpoint was histologic improvement (reduction of 2 or more points in overall NAS, with reduction of 1 or more points in more than one category of the NAS without worsening of fibrosis at the end of year 1. The key secondary endpoint was complete NASH resolution without worsening of fibrosis at year 2.

Dr. Landgren reported that, at year 1, of the total number of patients, 28.6% of those receiving cenicriviroc achieved an improvement in fibrosis of one or more stages, compared with 19.0% of those receiving placebo. Of the 97 patients who had advanced fibrosis at baseline, 38.3% of those on cenicriviroc and 28.0% of those on placebo achieved the same endpoint.

Those effects were sustained at year 2, Dr. Landgren emphasized, with twice as many cenicriviroc- than placebo-treated patients achieving one or more stage improvement in fibrosis and no worsening of NASH at year 2 (60% and 30%, respectively), with more pronounced improvements in those who had advanced fibrosis at baseline (86% and 60%).

In addition, analyses of biomarkers suggested that cenicriviroc had systematic anti-inflammatory activity, with reductions observed in high-sensitivity C-reactive protein; fibrinogen; and levels of interleukin-6, IL-8, and IL-1-beta.

Dr. Landgren and colleagues noted that cenicriviroc provided antifibrotic benefit in patients with NASH and fibrosis. Those benefits were sustained through year 2 and were more pronounced in patients who had advanced fibrosis at baseline.

The safety of cenicriviroc was “comparable with placebo,” he said, suggesting that the data supported the phase 3 AURORA study that is currently recruiting.

Tirzepatide for NASH

Another approach worth exploring for the treatment of NASH, is the use of tirzepatide, a dual agonist of glucose-dependent insulinotropic polypeptide and the glucagonlike peptide–1 (GLP-1) receptor, according to Axel Haupt, MD, PhD, of Eli Lilly.

Tirzepatide (LY3298176) is currently under investigation for the treatment of type 2 diabetes, and Dr. Haupt reported data from a post hoc analysis of a double-blind, placebo-controlled, phase 2b study showing that “exploratory” serum markers of apoptosis and fibrosis – keratin-18 (K-18) and Pro-C3, respectively – were decreased from baseline to a greater extent in patients treated with tirzepatide than with placebo, while total adiponectin was increased. The latter is “thought to protect the liver from inflammation and fibrosis,” Dr. Haupt observed.

The main results of the trial were published last year (Lancet. 2018;392:2180-93) and showed that, after 26 weeks, there was a dose-dependent decrease in both glycated hemoglobin (HbA_1c) and body weight with tirzepatide 10 mg and 15 mg, compared with placebo and an active comparator, dulaglutide 1.5 mg.

The study population was typical of type 2 diabetes: baseline HbA_1c was 8.1%; the average body mass index was 32 kg/m², with a diabetes duration of 5 years; and the main treatment (90%) had been metformin.

The rationale for the NASH-related biomarker analysis was that type 2 diabetes and NAFLD were known to be overlapping conditions, and weight loss had been shown to be an effective means of resolving NASH, Dr. Haupt said. In addition, a small “proof-of-concept” study with the GLP-1 receptor agonist liraglutide had suggested that these drugs may be effective in NASH.

Tirzepatide, at doses of 5, 10, and 15 mg, was associated with significant decreases in K-18 from baseline to week 26 and compared with placebo and the 1-mg tirzepatide dose. Mean baseline concentrations of K-18 were 394.4 U/L in the placebo group and reduced by 22.6 U/L by week 26. Corresponding baseline values for tirzepatide 5 mg were 375.8 U/L (change, –87.6 U/L); for 10 mg, 409.9 U/L (–157.8 U/L); and for 15 mg, 376.2 U/L (–110.6 U/L).

Dr. Haupt noted that a K-18 value of 250 U/L was considered a cutoff for a diagnosis of NASH. “So we really think that we have some NASH patients in this population,” he observed.

At week 26, Pro-C3 levels significantly decreased by 1.2 ng/mL from a baseline of 8.6 ng/mL with tirzepatide 15 mg, compared with an increase of 0.9 ng/mL from a baseline of 9.3 ng/mL for placebo (P less than .05). However, values of between 15-20 ng/mL would be expected for advanced fibrosis, Dr. Haupt said, “so we think we [don’t] have a lot of patients with advanced fibrosis, we have a lower grade of fibrosis or no fibrosis in our patient population.”

By week 26, adiponectin levels significantly increased by 0.9 mg/L from baseline, both with tirzepatide 10 mg (P less than .05) and 15 mg (P less than .05), compared with placebo (–0.1 mg/L; both P less than .05).

“This study was really designed as a type 2 diabetes efficacy study, so the NASH biomarker work is exploratory and only hypothesis generating,” Dr. Haupt noted. “We think there is overlap in type 2 diabetes and NASH, but it is not an ideal population to look into those biomarkers.” There are also other limitations, such as the baseline values across treatment groups not being matched, so there is likely to be some inconsistency in these data, he added.

That said, Dr. Haupt concluded that, “along with the weight-loss findings,” these exploratory biomarker findings supported the further evaluation of tirzepatide in patients with NASH.”

DURATION-8: Exenatide plus dapagliflozin

In another hypothesis-generating post hoc analysis, this time of the phase 3 DURATION-8 clinical trial, a combination of exenatide and dapagliflozin was found to have a beneficial effect on markers of hepatic steatosis and fibrosis in patients with type 2 diabetes.

“We have some good evidence that both GLP-1 receptor agonists and SGLT2 [sodium-glucose cotransporter 2] inhibitors may have benefits in reducing steatosis and even steatohepatitis in [patients with] type 2 diabetes. So the association of two diabetes drugs might provide an advantage. However, this had not previously been tested in a randomized, controlled trial,” observed Cristian Guja, MD, PhD, of Carol Davila University of Medicine and Pharmacy in Bucharest, Romania.

The main aims of the DURATION-8 clinical trial, which ran for 104 weeks, was to compare the efficacy and safety of combining exenatide (2 mg, once a week) and dapagliflozin (10 mg, daily) with either exenatide 2 mg with placebo or dapagliflozin 10 mg with placebo. Results showed greater improved glycemic control and reductions in body weight and systolic BP with the exenatide-dapagliflozin combination.

A total of 685 patients were included in the post hoc analysis, of whom 228 had been treated with the combination, 228 with exenatide plus placebo, and 230 with dapagliflozin plus placebo. At baseline, levels of the markers of NAFLD and fibrosis that were assessed were similar between the groups. Between 81% and 93% of study participants had fatty liver or steatosis as defined by a Fatty Liver Index (FLI) of 60 or more or an overall NAFLD Liver Fat Score (NLFS) of –0.64 or higher. Between 9% and 13% of patients had liver fibrosis, as defined as an NAFLD Fibrosis Score (NFS) above 0.676, a Fibrosis-4 score (FIB-4) of 1.46 or more, or both.

At 28 weeks, the proportion of patients with biomarker scores suggestive of fatty liver disease or steatosis was significantly reduced from baseline with the exenatide-dapagliflozin combination (–10.5% for FLI of 60 or more; –6.5% for NLFS of –0.640 or more), Dr. Guja said, and biomarker scores suggestive of advanced fibrosis (NFS greater than 0.676; FIB-4 of 1.46 or more) were reduced by 4.1% and 3.6%, respectively.

At 28 and 52 weeks, the combination therapy showed stronger effects than exenatide and dapagliflozin alone in improving markers of hepatic steatosis (FLI: 28 weeks, –6.81, –3.90, –4.04; and 52 weeks, –6.23, –3.00, –4.58). The combination therapy also showed improvement for advanced fibrosis biomarkers at both time points (FIB-4: 28 weeks, –0.06, –0.03, –0.04; and 52 weeks, –0.05, –0.02, –0,04).

Dr. Guja noted that, although the study was not powered to assess the effect of on fatty liver, making all these data exploratory, this was the first analysis to describe improvements in biomarkers of fatty liver or steatosis and fibrosis from a large trial. “Some specific, dedicated, prospective trials are needed in the future to validate these findings.”

The CENTAUR study was funded by Allergan, of which Dr. Landgren is an employee. The phase 2b study with tirzepatide was supported by Eli Lilly. Dr. Haupt disclosed being an employee and also holding stocks in the company. The DURATION-8 study was sponsored by AstraZeneca. Dr. Guja disclosed that he had participated in scientific advisory boards and received consulting fees from AstraZeneca and other companies.

BARCELONA – The investigational oral agent cenicriviroc showed positive effects on liver fibrosis in adults with nonalcoholic steatohepatitis (NASH), many of whom had type 2 diabetes, in a phase 2b trial reported at the annual meeting of the European Association for the Study of Diabetes.

Other data released at the meeting, which showed potential positive effects of novel or existing diabetes treatments on nonalcoholic fatty liver disease (NAFLD), included post hoc analyses of a phase 2b study with tirzepatide and a phase 3 study that combined exenatide and dapagliflozin.

Currently, no medications for NAFLD or NASH have been approved in the United States.

CENTAUR with cenicriviroc

Results of the previously reported CENTAUR trial showed that the antifibrotic effects of cenicriviroc, a dual chemokine receptor antagonist, were greatest in patients with more-severe liver disease (Hepatology. 2018;67[5]:1754-67). At the meeting, Henrik Landgren, PhD, of Allergan, presented data from the 2-year trial overall, and specifically in patients with advanced, stage 3 fibrosis.

CENTAUR was a randomized, double-blind, placebo-controlled, multinational study with 289 adults who had biopsy-confirmed NASH, an NAFLD Activity Score (NAS; range, 0-8; score of 5 or more diagnostic of NASH) of 4 or more, and stages 1-3 liver fibrosis as determined by the NASH clinical research network system (Contemp Clin Trials. 2016;47:356-65). The mean age of the patients enrolled at baseline was 54 years, the mean body mass index was 33.9 kg/m², and just more than half the patients (52%) had type 2 diabetes.

The patients were randomized to three treatment arms: cenicriviroc 150 mg for 2 years; placebo for 1 year, then cenicriviroc 150 mg for 1 year; or placebo for 2 years. The primary endpoint was histologic improvement (reduction of 2 or more points in overall NAS, with reduction of 1 or more points in more than one category of the NAS without worsening of fibrosis at the end of year 1. The key secondary endpoint was complete NASH resolution without worsening of fibrosis at year 2.

Dr. Landgren reported that, at year 1, of the total number of patients, 28.6% of those receiving cenicriviroc achieved an improvement in fibrosis of one or more stages, compared with 19.0% of those receiving placebo. Of the 97 patients who had advanced fibrosis at baseline, 38.3% of those on cenicriviroc and 28.0% of those on placebo achieved the same endpoint.

SAN ANTONIO – The therapeutic Dark Ages of nonalcoholic steatohepatitis (NASH) are finally drawing to a close.

“NASH-specific therapies are coming soon – sooner than you think,” Naim Alkhouri, MD, predicted at the annual meeting of the American College of Gastroenterology.

And that, he added, has important implications for clinical practice. Physicians are going to need to step up their game with regard to screening and staging patients with nonalcoholic fatty liver disease to identify the right candidates for the coming effective treatments.

The new treatment era in NASH could dawn as soon as the spring of 2020, by which time the Food and Drug Administration is expected to issue a decision on obeticholic acid, an oral FXR agonist for which the agency has granted breakthrough therapy status. Intercept Pharmaceuticals has filed for marketing approval of obeticholic acid for NASH on the strength of the positive 18-month histologic results of the pivotal phase 3 REGENERATE trial, the first-ever successful phase 3 study of a medication for NASH, noted Dr. Alkhouri, a gastroenterologist at the University of Texas, San Antonio, and director of the Metabolic Health Center at the Texas Liver Institute.

At present there are no FDA-approved pharmacotherapies for NASH. The unmet medical need is huge, since NASH is now recognized to be a full-blown, burgeoning epidemic. NASH will soon become the No. 1 indication for liver transplantation in the United States. A full-throttle race is on to find effective therapies targeting the various dimensions of NASH, with more than 70 drugs now in phase 2 studies. These drugs collectively address all four mechanisms of the disease’s development and progression: the metabolic targets, perturbations in the gut-liver axis, liver inflammation, and fibrosis.

Moreover, even as the FDA considers the application for approval of obeticholic acid in NASH, at least four other investigational drugs are in pivotal phase 3 clinical trials. These include elafibranor, aramchol, resmetirom, and cenicriviroc.

Cenicriviroc is a dual CCR 2/5 receptor antagonist that targets the hepatic inflammation and fibrosis dimensions of NASH. It is now being evaluated in the phase 3 AURORA trial on the strength of the earlier positive phase 2b Centaur study, in which patients randomized to cenicriviroc were twice as likely to experience significant improvement in fibrosis as were placebo-treated controls.

Elafibranor, aramchol, and resmetirom employ different mechanisms of action to address the metabolic derangements of NASH. What they share in common is their aim to reduce the influx of free fatty acids from adipose tissue to the liver, and/or to inhibit lipogenesis from carbohydrate building blocks. In so doing, these medications should result in reduced hepatocyte injury and liver inflammation.

Elafibranor is a peroxisome proliferator-activated receptor alpha/delta agonist that achieved significant biopsy-proven reversal of NASH in moderate- or severely affected patients in the phase 2 GOLDEN study. The phase 3 RESOLVE IT trial is underway.

Aramchol is a first-in-class synthetic fatty acid/bile acid conjugate that inhibits stearoyl-CoA desaturate activity. It’s designed to improve insulin resistance and curb accumulation of triglycerides in hepatocytes. In the 52-week, phase 2 ARREST trial, oral aramchol at 600 mg/day was 4.7-fold more likely than was placebo to achieve NASH resolution without worsening of fibrosis. The drug is now in phase 3 in the ARMOR study.

Resmetirom is a selective thyroid hormone receptor–beta agonist. Activation of the beta receptor lowers LDL cholesterol, triglycerides, and liver fat, whereas activation of the alpha receptor has the unwanted effects of promoting bone loss, thyrotoxicosis, and arrhythmias. In phase 2, 75% of patients on high-dose resmetirom achieved at least a 30% reduction in hepatic fat by MRI at week 12, compared with 18% of placebo-treated controls. And 39% of the high-dose resmetirom group showed histologic resolution of NASH on a week-36 liver biopsy, as did a mere 6% of controls. The phase 3 MAESTRO randomized trial is underway.

Obeticholic acid addresses the gut-liver axis abnormalities present in NASH, especially the exuberant bile acid circulation.

Clinical implications of the coming wave of medications

In Dr. Alkhouri’s view, the target population for pharmacotherapy will be NASH patients with advanced disease, but not too far advanced; that is, those with stage 2 or 3 fibrotic changes in addition to liver inflammation, hepatocyte injury, and steatosis.

“These are the patients with a high chance of progressing to cirrhosis and end-stage liver disease,” the gastroenterologist said.

Patients with earlier-stage nonalcoholic fatty liver disease are best managed via lifestyle changes, with particular emphasis upon 10% weight loss accompanied by exercise. And patients with more advanced disease – NASH with cirrhosis – appear thus far to be beyond the reach of the next-generation therapies.

None of the coming drugs is a cure-all. In the landmark phase 3 REGENERATE trial, for example, the rate of the primary outcome – fibrosis improvement of at least one stage plus no worsening of NASH at 18 months – was 23% in patients randomized to obeticholic acid at 25 mg/day, compared to 12% with placebo.

“These are not like hepatitis C medications, with 97% efficacy, so combination therapy targeting upstream and downstream for NASH is rational,” Dr. Alkhouri observed.

He reported serving on advisory boards for Allergan, Gilead, and Intercept, and receiving research grants from those companies as well as from Galmed, Genfit, and Madrigal.
