Hepatology

The US Food and Drug Administration (FDA) granted accelerated approval for Livdelzi (seladelpar, Gilead Sciences, Inc.) for primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who fail to respond adequately to UDCA, or as monotherapy in those who can’t tolerate UDCA. 

Livdelzi, a selective agonist of peroxisome proliferator–activated receptor delta, is not recommended in adults who have or develop decompensated cirrhosis.

PBC is a rare, chronic, autoimmune disease of the bile ducts that affects roughly 130,000 Americans, primarily women, and can cause liver damage and possible liver failure if untreated. The disease currently has no cure.

The FDA approved Livdelzi based largely on results of the phase 3 RESPONSE study, in which the drug significantly improved liver biomarkers of disease activity and bothersome symptoms of pruritus in adults with PBC.

The primary endpoint of the trial was a biochemical response, defined as an alkaline phosphatase (ALP) level < 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level, at 12 months.

After 12 months, 62% of patients taking Livdelzi met the primary endpoint vs 20% of patients taking placebo.

In addition, significantly more patients taking Livdelzi than placebo had normalization of the ALP level (25% vs 0%). The average decrease in ALP from baseline was 42.4% in the Livdelzi group vs 4.3% in the placebo group.

At 12 months, alanine aminotransferase and gamma-glutamyl transferase levels were reduced by 23.5% and 39.1%, respectively, in the Livdelzi group compared with 6.5% and 11.4%, respectively, in the placebo group.

A key secondary endpoint was change in patient-reported pruritus.

At baseline, 38.3% of patients in the Livdelzi group and 35.4% of those in the placebo group had moderate to severe pruritus, with a daily numerical rating scale (NRS) score ≥ 4 out of 10.

Among these patients, the reduction from baseline in the pruritus NRS score at month 6 was significantly greater with Livdelzi than with placebo (change from baseline, -3.2 vs -1.7 points). These improvements were sustained through 12 months.

Improvements on the 5-D Itch Scale in both the moderate- to severe-pruritis population and the overall population also favored Livdelzi over placebo for itch relief, which had a positive impact on sleep.

“The availability of a new treatment option that can help reduce [the] intense itching while also improving biomarkers of active liver disease is a milestone for our community,” Carol Roberts, president, The PBCers Organization, said in a news release announcing the approval. 

The most common adverse reactions with Livdelzi were headache, abdominal pain, nausea, abdominal distension, and dizziness.

The company noted that the FDA granted accelerated approval for Livdelzi based on a reduction of ALP. Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval of Livdelzi for PBC may be contingent on verification and description of clinical benefit in confirmatory trial(s).

TOPLINE:

The estimated number of US adults who consumed at least one of the six most frequently reported hepatotoxic botanicals in the last 30 days is similar to the number of patients prescribed potentially hepatotoxic drugs, including nonsteroidal anti-inflammatory drugs (NSAIDs) and simvastatin.

METHODOLOGY:

• Herbal and dietary supplements (HDS) are an increasingly common source of drug hepatotoxicity cases, but their prevalence and the reasons for their use among the general population are uncertain.
• This survey study evaluated nationally representative data from 9685 adults (mean age, 47.5 years; 51.8% women) enrolled in the National Health and Nutrition Examination Survey (NHANES) between January 2017 and March 2020.
• Participants reported their use of HDS and prescription drugs through personal interviews for a 30-day period prior to the survey date.
• Researchers compared the clinical features and baseline demographic characteristics of users of six potentially hepatotoxic botanicals (ie, turmeric, green tea, Garcinia cambogia, black cohosh, red yeast rice, and ashwagandha) with those of nonusers.
• The prevalence of use of these at-risk botanicals was compared with that of widely prescribed potentially hepatotoxic medications, including NSAIDs, simvastatin, and sertraline.

TAKEAWAY:

• In the cohort of 9685 participants, 4.7% of individuals reported consumption of at least one of the six potentially hepatotoxic botanicals in the past 30 days, with turmeric being the most common, followed by green tea.
• Extrapolating the survey data, researchers estimated that 15.6 million US adults use at least one of these six botanicals, which is comparable to the number of those prescribed potentially hepatotoxic drugs, including NSAIDs (14.8 million) and simvastatin (14.0 million). Sertraline use was lower (7.7 million).
• Most individuals used these botanicals without the recommendation of their healthcare provider.
• Those using botanicals were more likely to be older (adjusted odds ratio [aOR], 2.36; P = .04 for 40-59 years; aOR, 3.96; P = .001 for ≥ 60 years), to have some college education (aOR, 4.78; P < .001), and to have arthritis (aOR, 2.27; P < .001) than nonusers.
• The most common reasons for using any of these six potential hepatotoxic botanicals were to improve or maintain health or to prevent health problems or boost immunity.

IN PRACTICE:

“In light of the lack of regulatory oversight on the manufacturing and testing of botanical products, it is recommended that clinicians obtain a full medication and HDS use history when evaluating patients with unexplained symptoms or liver test abnormalities,” the authors wrote.

SOURCE:

The study, led by Alisa Likhitsup, MD, MPH, Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan, was published online in JAMA Network Open. 

LIMITATIONS:

The survey response rate was low at 43.9% for adults aged ≥ 20 years. As NHANES is a cross-sectional study, the causal relationship between consumption of the six botanicals of interest and the development of liver injury could not be determined. The use of HDS products and medications was self-reported in NHANES and not independently verified using source documents. 

DISCLOSURES:

This study did not report any source of funding. Two authors declared receiving grants from pharmaceutical companies outside the submitted work.

TOPLINE:

Greater availability of peripheral tri-iodothyronine (T3), indicated by higher concentrations of free T3, T3, and T3/thyroxine (T4) ratio, is associated with increased liver fat content at baseline and a greater liver fat reduction following a dietary intervention known to reduce liver fat.

METHODOLOGY:

• Systemic hypothyroidism and subclinical hypothyroidism are proposed as independent risk factors for steatotic liver disease, but there are conflicting results in euthyroid individuals with normal thyroid function.
• Researchers investigated the association between thyroid function and intrahepatic lipids in 332 euthyroid individuals aged 50-80 years who reported limited alcohol consumption and had at least one condition for unhealthy aging (eg, cardiovascular disease).
• The analysis drew on a sub-cohort from the NutriAct trial, in which participants were randomly assigned to either an intervention group (diet rich in unsaturated fatty acids, plant protein, and fiber) or a control group (following the German Nutrition Society recommendations).
• The relationship between changes in intrahepatic lipid content and thyroid hormone parameters was evaluated in 243 individuals with data available at 12 months.

TAKEAWAY:

• Higher levels of free T3 and T3/T4 ratio were associated with increased liver fat content at baseline (P = .03 and P = .01, respectively).
• After 12 months, both the intervention and control groups showed reductions in liver fat content, along with similar reductions in free T3, total T3, T3/T4 ratio, and free T3/free T4 ratio (all P < .01).
• Thyroid stimulating hormone, T4, and free T4 levels remained stable in either group during the intervention.
• Participants who maintained higher T3 levels during the dietary intervention experienced a greater reduction in liver fat content over 12 months (Rho = −0.133; P = .039).

IN PRACTICE:

“A higher peripheral concentration of active THs [thyroid hormones] might reflect a compensatory mechanism in subjects with mildly increased IHL [intrahepatic lipid] content and early stages of MASLD [metabolic dysfunction–associated steatotic liver disease],” the authors wrote.

SOURCE:

The study was led by Miriam Sommer-Ballarini, Charité–Universitätsmedizin Berlin, Berlin, Germany. It was published online in the European Journal of Endocrinology.

LIMITATIONS:

Participants younger than 50 years of age and with severe hepatic disease, severe substance abuse, or active cancer were excluded, which may limit the generalizability of the findings. Because the study cohort had only mildly elevated median intrahepatic lipid content at baseline, it may not be suited to address the advanced stages of metabolic dysfunction–associated steatotic liver disease. The study’s findings are based on a specific dietary intervention, which may not be applicable to other dietary patterns or populations.

The Deutsche Forschungsgemeinschaft and German Federal Ministry for Education and Research funded this study. Some authors declared receiving funding, serving as consultants, or being employed by relevant private companies.

Patients with dementia may instead have hepatic encephalopathy and should be screened with the Fibrosis-4 (FIB-4) index for cirrhosis, one of the main causes of the condition, new research suggests.

The study of more than 68,000 individuals in the general population diagnosed with dementia between 2009 and 2019 found that almost 13% had FIB-4 scores indicative of cirrhosis and potential hepatic encephalopathy.

The findings, recently published online in The American Journal of Medicine, corroborate and extend the researchers’ previous work, which showed that about 10% of US veterans with a dementia diagnosis may in fact have hepatic encephalopathy.

“We need to increase awareness that cirrhosis and related brain complications are common, silent, but treatable when found,” said corresponding author Jasmohan Bajaj, MD, of Virginia Commonwealth University and Richmond VA Medical Center, Richmond, Virginia. “Moreover, these are being increasingly diagnosed in older individuals.”

“Cirrhosis can also predispose patients to liver cancer and other complications, so diagnosing it in all patients is important, regardless of the hepatic encephalopathy-dementia connection,” he said.
 

FIB-4 Is Key

Dr. Bajaj and colleagues analyzed data from 72 healthcare centers on 68,807 nonveteran patients diagnosed with dementia at two or more physician visits between 2009 and 2019. Patients had no prior cirrhosis diagnosis, the mean age was 73 years, 44.7% were men, and 78% were White.

The team measured the prevalence of two high FIB-4 scores (> 2.67 and > 3.25), selected for their strong predictive value for advanced cirrhosis. Researchers also examined associations between high scores and multiple comorbidities and demographic factors.

Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet labs were collected up to 2 years after the index dementia diagnosis because they are used to calculate FIB-4.

The mean FIB-4 score was 1.78, mean ALT was 23.72 U/L, mean AST was 27.42 U/L, and mean platelets were 243.51 × 109/µL.

A total of 8683 participants (12.8%) had a FIB-4 score greater than 2.67 and 5185 (7.6%) had a score greater than 3.25.

In multivariable logistic regression models, FIB-4 greater than 3.25 was associated with viral hepatitis (odds ratio [OR], 2.23), congestive heart failure (OR,1.73), HIV (OR, 1.72), male gender (OR, 1.42), alcohol use disorder (OR, 1.39), and chronic kidney disease (OR, 1.38).

FIB-4 greater than 3.25 was inversely associated with White race (OR, 0.76) and diabetes (OR, 0.82).

The associations were similar when using a threshold score of greater than 2.67.

“With the aging population, including those with cirrhosis, the potential for overlap between hepatic encephalopathy and dementia has risen and should be considered in the differential diagnosis,” the authors wrote. “Undiagnosed cirrhosis and potential hepatic encephalopathy can be a treatable cause of or contributor towards cognitive impairment in patients diagnosed with dementia.”

Providers should use the FIB-4 index as a screening tool to detect cirrhosis in patients with dementia, they concluded.

The team’s next steps will include investigating barriers to the use of FIB-4 among practitioners, Dr. Bajaj said.

Incorporating use of the FIB-4 index into screening guidelines “with input from all stakeholders, including geriatricians, primary care providers, and neurologists … would greatly expand the diagnosis of cirrhosis and potentially hepatic encephalopathy in dementia patients,” Dr. Bajaj said.

The study had a few limitations, including the selected centers in the cohort database, lack of chart review to confirm diagnoses in individual cases, and the use of a modified FIB-4, with age capped at 65 years.
 

‘Easy to Miss’

Commenting on the research, Nancy Reau, MD, section chief of hepatology at Rush University Medical Center in Chicago, said that it is easy for physicians to miss asymptomatic liver disease that could progress and lead to cognitive decline.

“Most of my patients are already labeled with liver disease; however, it is not uncommon to receive a patient from another specialist who felt their presentation was more consistent with liver disease than the issue they were referred for,” she said.

Still, even in metabolic dysfunction–associated steatotic liver disease, which affects nearly one third of the population, the condition isn’t advanced enough in most patients to cause symptoms similar to those of dementia, said Dr. Reau, who was not associated with the study.

“It is more important for specialists in neurology to exclude liver disease and for hepatologists or gastroenterologists to be equipped with tools to exclude alternative explanations for neurocognitive presentations,” she said. “It is important to not label a patient as having HE and then miss alternative explanations.”

“Every presentation has a differential diagnosis. Using easy tools like FIB-4 can make sure you don’t miss liver disease as a contributing factor in a patient that presents with neurocognitive symptoms,” Dr. Reau said.

Patients with dementia may instead have hepatic encephalopathy and should be screened with the Fibrosis-4 (FIB-4) index for cirrhosis, one of the main causes of the condition, new research suggests.

The study of more than 68,000 individuals in the general population diagnosed with dementia between 2009 and 2019 found that almost 13% had FIB-4 scores indicative of cirrhosis and potential hepatic encephalopathy.

The findings, recently published online in The American Journal of Medicine, corroborate and extend the researchers’ previous work, which showed that about 10% of US veterans with a dementia diagnosis may in fact have hepatic encephalopathy.

“We need to increase awareness that cirrhosis and related brain complications are common, silent, but treatable when found,” said corresponding author Jasmohan Bajaj, MD, of Virginia Commonwealth University and Richmond VA Medical Center, Richmond, Virginia. “Moreover, these are being increasingly diagnosed in older individuals.”

“Cirrhosis can also predispose patients to liver cancer and other complications, so diagnosing it in all patients is important, regardless of the hepatic encephalopathy-dementia connection,” he said.
 

FIB-4 Is Key

Dr. Bajaj and colleagues analyzed data from 72 healthcare centers on 68,807 nonveteran patients diagnosed with dementia at two or more physician visits between 2009 and 2019. Patients had no prior cirrhosis diagnosis, the mean age was 73 years, 44.7% were men, and 78% were White.

The team measured the prevalence of two high FIB-4 scores (> 2.67 and > 3.25), selected for their strong predictive value for advanced cirrhosis. Researchers also examined associations between high scores and multiple comorbidities and demographic factors.

Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet labs were collected up to 2 years after the index dementia diagnosis because they are used to calculate FIB-4.

The mean FIB-4 score was 1.78, mean ALT was 23.72 U/L, mean AST was 27.42 U/L, and mean platelets were 243.51 × 109/µL.

A total of 8683 participants (12.8%) had a FIB-4 score greater than 2.67 and 5185 (7.6%) had a score greater than 3.25.

In multivariable logistic regression models, FIB-4 greater than 3.25 was associated with viral hepatitis (odds ratio [OR], 2.23), congestive heart failure (OR,1.73), HIV (OR, 1.72), male gender (OR, 1.42), alcohol use disorder (OR, 1.39), and chronic kidney disease (OR, 1.38).

FIB-4 greater than 3.25 was inversely associated with White race (OR, 0.76) and diabetes (OR, 0.82).

The associations were similar when using a threshold score of greater than 2.67.

“With the aging population, including those with cirrhosis, the potential for overlap between hepatic encephalopathy and dementia has risen and should be considered in the differential diagnosis,” the authors wrote. “Undiagnosed cirrhosis and potential hepatic encephalopathy can be a treatable cause of or contributor towards cognitive impairment in patients diagnosed with dementia.”

Providers should use the FIB-4 index as a screening tool to detect cirrhosis in patients with dementia, they concluded.

The team’s next steps will include investigating barriers to the use of FIB-4 among practitioners, Dr. Bajaj said.

Incorporating use of the FIB-4 index into screening guidelines “with input from all stakeholders, including geriatricians, primary care providers, and neurologists … would greatly expand the diagnosis of cirrhosis and potentially hepatic encephalopathy in dementia patients,” Dr. Bajaj said.

The study had a few limitations, including the selected centers in the cohort database, lack of chart review to confirm diagnoses in individual cases, and the use of a modified FIB-4, with age capped at 65 years.

TOPLINE:

An analysis of real-world evidence identified 17 medications, many not previously regarded as potentially hepatotoxic, that have high incidence rates of patient hospitalization for acute liver injury (ALI), offering insights on how to better determine which drugs carry the most significant risk and warrant liver monitoring.

METHODOLOGY:

• Without a systematic approach to classifying medications’ hepatotoxic risk, researchers have used case reports published on the National Institutes of Health’s LiverTox, which doesn’t account for the number of people exposed, to categorize drugs’ likelihood of causing ALI. The objective was to identify the most potentially hepatotoxic medications using real-world incidence rates of severe ALI.
• Researchers analyzed US Department of Veterans Affairs electronic health record data for almost 7.9 million individuals (mean age, 64.4 years; 92.5% men) without preexisting liver or biliary disease who were initiated in an outpatient setting on any one of 194 medications with four or more published reports of hepatotoxicity. Drugs delivered by injection or intravenously, prescribed for alcohol use disorder or liver disease treatment, or used as an anticoagulant were not included in the study.
• The primary outcome measured was hospitalization for severe ALI, defined by alanine aminotransferase levels > 120 U/L and total bilirubin levels > 2.0 mg/dL or the international normalized ratio ≥ 1.5 and total bilirubin levels > 2.0 mg/dL within the first 2 days of admission.
• Researchers organized the medications into groups on the basis of observed rates of severe ALI per 10,000 person-years and classified drugs with 10 or more hospitalizations (group 1) and 5-9.9 hospitalizations (group 2) as the most potentially hepatotoxic. The study period was October 2000 through September 2021.

TAKEAWAY:

• Among the study population, 1739 hospitalizations for severe ALI were identified. Incidence rates of severe ALI varied widely by medication, from 0 to 86.4 events per 10,000 person-years.
• Seventeen medications were classified as the most potentially hepatotoxic (groups 1 and 2). Seven of them (stavudine, erlotinib, lenalidomide or thalidomide, chlorpromazine, metronidazole, prochlorperazine, and isoniazid) had incidence rates of ≥ 10 events per 10,000 person-years. The other 10 medications (moxifloxacin, azathioprine, levofloxacin, clarithromycin, ketoconazole, fluconazole, captopril, amoxicillin-clavulanate, sulfamethoxazole-trimethoprim, and ciprofloxacin) showed incidence rates of 5-9.9 events per 10,000 person-years.
• Of the 17 most hepatotoxic medications, 11 (64%) were not classified as highly hepatotoxic in the published case reports, suggesting a discrepancy between real-world data and case report categorizations.
• Similarly, several medications, including some statins, identified as low-risk in this study were classified as among the most hepatotoxic in the published case reports.

IN PRACTICE:

“Categorization of hepatotoxicity based on the number of published case reports did not accurately reflect observed rates of severe ALI (acute liver injury),” the researchers wrote. “This study represents a systematic, reproducible approach to using real-world data to measure rates of severe ALI following medication initiation among patients without liver or biliary disease…Patients initiating a medication with a high rate of severe ALI might require closer monitoring of liver-related laboratory tests to detect evolving hepatic dysfunction earlier, which might improve prognosis.”

The study illustrates the potential to use electronic health record data to “revolutionize how we characterize drug-related toxic effects,” not just on the liver but other organs, Grace Y. Zhang, MD, and Jessica B. Rubin, MD, MPH, of the University of California, San Francisco, wrote in an accompanying editorial. “If curated and disseminated effectively…such evidence will undoubtedly improve clinical decision-making and allow for more informed patient counseling regarding the true risks of starting or discontinuing medications.

SOURCE:

The study, led by Jessie Torgersen, MD, MHS, MSCE, of the Division of Infectious Diseases, Department of Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, was published online in JAMA Internal Medicine.

LIMITATIONS:

The researchers listed several limitations, including the possibility that reliance on laboratory tests for ascertainment of acute liver injuries could introduce surveillance bias. The study focused on a population predominantly consisting of men without preexisting liver or biliary disease, so the findings may not be generalizable to women or individuals with liver disease. Additionally, researchers did not perform a causality assessment of all outcomes, did not study medications with fewer than four published case reports, and did not evaluate the influence of dosage.

DISCLOSURES:

This study was partly funded by several grants from the National Institutes of Health. Some authors declared receiving grants and personal fees from some of the funding agencies and other sources outside of this work.

The combination of the antiviral bulevirtide (Hepcludex) plus pegylated interferon alfa-2a was superior to bulevirtide monotherapy for chronic hepatitis delta (HDV) infection, a multinational phase 2b open-label study in Europe found.

The combination resulted in higher rates of HDV RNA suppression levels at 24 weeks after end of treatment, especially at a higher, 10-mg dose of bulevirtide, according to researchers led by Tarik Asselah, MD. PhD, a professor of medicine and hepatology at Hôpital Beaujon, APHP, Clichy, France, and the University of Paris.

“This response appeared to be maintained from 24-48 weeks after the end of treatment — a finding that supports the concept that sustained undetectable HDV RNA for at least 1 year after treatment is possible in patients with chronic hepatitis D who have been treated with a finite duration of therapy of at least 96 weeks, including 48 weeks of peginterferon alfa-2a therapy,” the investigators wrote in The New England Journal of Medicine.

“As of today, there is no approved treatment for chronic HDV infection in the United States. Pegylated interferon alfa-2a, which is not approved for treatment of HDV, is the only option recommended by US treatment guidelines,” said study corresponding author Fabien Zoulim, MD, PhD, a hepatologist at the Lyon Hepatology Institute and a professor of medicine at the University of Lyon in France, in comments to GI & Hepatology News. “Bulevirtide 2 mg is approved for treating chronic HDV and compensated liver disease, and both bulevirtide and peginterferon are recommended options by the European treatment guidelines.”

The study found that most patients with undetectable HDV RNA levels during treatment-free follow-up showed no reduction in HepB surface antigen (HBsAg), suggesting an undetectable HDV RNA level can be achieved and sustained without HBsAg loss, the authors wrote.

While very small numbers in the combo groups and the higher-dose bulevirtide arm cleared HBsAg, “the study was not powered to evaluate the HBsAg response,” Dr. Zoulim said.

HDV is a defective virus that requires HBsAg for assembly and propagation, the authors noted. It affects as many as 20 million persons worldwide, and as the most severe form of chronic viral hepatitis, is associated with 2-6 times the risk of hepatocellular carcinoma and 2-3 times the risk of death associated with HBV monoinfection.

Though not common in the United States, it affects an estimated 10 to 20 million people worldwide (J Hepatol. 2020 Apr. doi: 10.1016/j.jhep.2020.04.008). One US database study found HepD in 4.6% of patients with HepB infection.

Commenting on the study but not a participant in it, Ahmet O. Gurakar, MD, AGAF, a professor of medicine in the sections of gastroenterology and hepatology at Johns Hopkins School of Medicine in Baltimore, Maryland, said the study findings look promising for the future treatment of HepD, but cautioned that it will be “a slow process to get approval for combination therapy with bulevirtide since the FDA has previously said it needs to see more studies. The findings need to be confirmed in larger groups, but it’s difficult to recruit enough patients in the United States for a trial since hepatitis D is not common in this country — it’s more common in the Mediterranean basin Eastern European populations.”

The Trial

The investigators randomly assigned 174, largely male, patients ages 18-65 (mean, about 41) years to receive one of four treatments:

• Pegylated interferon alfa-2a alone at 180 μg per week) for 48 weeks (n = 24).
• Bulevirtide at a daily dose of 2 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at 10 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at a daily dose of 10 mg alone for 96 weeks (n = 50).

All were followed for 48 weeks after treatment. The primary comparison was between the 10-mg bulevirtide plus peginterferon alfa-2a group and the 10-mg bulevirtide monotherapy group.

At 24 weeks post-treatment, HDV RNA was undetectable in 17% of patients in the peginterferon alfa-2a group. In the other arms, HDV RNA was undetectable in 32% in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of the 10-mg bulevirtide group.

For the primary comparison, the between-group difference was 34 percentage points (95% confidence interval, 15-50; P < .001).

At 48 weeks after the end of treatment, HDV RNA was undetectable in 25% in the peginterferon alfa-2a group, 26% in the 2-mg bulevirtide plus peginterferon alfa-2a group, 46% in the 10-mg bulevirtide plus peginterferon alfa-2a group, and 12% in the 10-mg bulevirtide group.

Also calling the findings promising, Anna Lok, MBBS, MD, AGAF, a gastroenterologist at the University of Michigan, Ann Arbor, said that, “Given that the European Medicines Agency’s approval is for bulevirtide alone at 2 mg, results of this study should prompt reassessment whether bulevirtide should be used in combination with pegylated interferon in patients with no contraindications, and if 10 mg is more appropriate than a 2-mg dose.”

The combination of the antiviral bulevirtide (Hepcludex) plus pegylated interferon alfa-2a was superior to bulevirtide monotherapy for chronic hepatitis delta (HDV) infection, a multinational phase 2b open-label study in Europe found.

The combination resulted in higher rates of HDV RNA suppression levels at 24 weeks after end of treatment, especially at a higher, 10-mg dose of bulevirtide, according to researchers led by Tarik Asselah, MD. PhD, a professor of medicine and hepatology at Hôpital Beaujon, APHP, Clichy, France, and the University of Paris.

“As of today, there is no approved treatment for chronic HDV infection in the United States. Pegylated interferon alfa-2a, which is not approved for treatment of HDV, is the only option recommended by US treatment guidelines,” said study corresponding author Fabien Zoulim, MD, PhD, a hepatologist at the Lyon Hepatology Institute and a professor of medicine at the University of Lyon in France, in comments to GI & Hepatology News. “Bulevirtide 2 mg is approved for treating chronic HDV and compensated liver disease, and both bulevirtide and peginterferon are recommended options by the European treatment guidelines.”

The study found that most patients with undetectable HDV RNA levels during treatment-free follow-up showed no reduction in HepB surface antigen (HBsAg), suggesting an undetectable HDV RNA level can be achieved and sustained without HBsAg loss, the authors wrote.

While very small numbers in the combo groups and the higher-dose bulevirtide arm cleared HBsAg, “the study was not powered to evaluate the HBsAg response,” Dr. Zoulim said.

HDV is a defective virus that requires HBsAg for assembly and propagation, the authors noted. It affects as many as 20 million persons worldwide, and as the most severe form of chronic viral hepatitis, is associated with 2-6 times the risk of hepatocellular carcinoma and 2-3 times the risk of death associated with HBV monoinfection.

Though not common in the United States, it affects an estimated 10 to 20 million people worldwide (J Hepatol. 2020 Apr. doi: 10.1016/j.jhep.2020.04.008). One US database study found HepD in 4.6% of patients with HepB infection.

Commenting on the study but not a participant in it, Ahmet O. Gurakar, MD, AGAF, a professor of medicine in the sections of gastroenterology and hepatology at Johns Hopkins School of Medicine in Baltimore, Maryland, said the study findings look promising for the future treatment of HepD, but cautioned that it will be “a slow process to get approval for combination therapy with bulevirtide since the FDA has previously said it needs to see more studies. The findings need to be confirmed in larger groups, but it’s difficult to recruit enough patients in the United States for a trial since hepatitis D is not common in this country — it’s more common in the Mediterranean basin Eastern European populations.”

The Trial

The investigators randomly assigned 174, largely male, patients ages 18-65 (mean, about 41) years to receive one of four treatments:

• Pegylated interferon alfa-2a alone at 180 μg per week) for 48 weeks (n = 24).
• Bulevirtide at a daily dose of 2 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at 10 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at a daily dose of 10 mg alone for 96 weeks (n = 50).

All were followed for 48 weeks after treatment. The primary comparison was between the 10-mg bulevirtide plus peginterferon alfa-2a group and the 10-mg bulevirtide monotherapy group.

At 24 weeks post-treatment, HDV RNA was undetectable in 17% of patients in the peginterferon alfa-2a group. In the other arms, HDV RNA was undetectable in 32% in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of the 10-mg bulevirtide group.

For the primary comparison, the between-group difference was 34 percentage points (95% confidence interval, 15-50; P < .001).

At 48 weeks after the end of treatment, HDV RNA was undetectable in 25% in the peginterferon alfa-2a group, 26% in the 2-mg bulevirtide plus peginterferon alfa-2a group, 46% in the 10-mg bulevirtide plus peginterferon alfa-2a group, and 12% in the 10-mg bulevirtide group.

Also calling the findings promising, Anna Lok, MBBS, MD, AGAF, a gastroenterologist at the University of Michigan, Ann Arbor, said that, “Given that the European Medicines Agency’s approval is for bulevirtide alone at 2 mg, results of this study should prompt reassessment whether bulevirtide should be used in combination with pegylated interferon in patients with no contraindications, and if 10 mg is more appropriate than a 2-mg dose.”

The combination of the antiviral bulevirtide (Hepcludex) plus pegylated interferon alfa-2a was superior to bulevirtide monotherapy for chronic hepatitis delta (HDV) infection, a multinational phase 2b open-label study in Europe found.

The combination resulted in higher rates of HDV RNA suppression levels at 24 weeks after end of treatment, especially at a higher, 10-mg dose of bulevirtide, according to researchers led by Tarik Asselah, MD. PhD, a professor of medicine and hepatology at Hôpital Beaujon, APHP, Clichy, France, and the University of Paris.

“This response appeared to be maintained from 24-48 weeks after the end of treatment — a finding that supports the concept that sustained undetectable HDV RNA for at least 1 year after treatment is possible in patients with chronic hepatitis D who have been treated with a finite duration of therapy of at least 96 weeks, including 48 weeks of peginterferon alfa-2a therapy,” the investigators wrote in The New England Journal of Medicine.

MILAN — Liver transplantation improves survival in patients with acute-on-chronic liver failure (ACLF), according to interim clinical outcomes of the large, international CHANCE study.

To date, the results show that 3-month post–liver transplantation mortality rates in patients with ACLF grades 2 and 3 were only 9%, which is not significantly different than that of patients with decompensated cirrhosis, with a mortality of 7%.

University College London Hospitals

“Treatment of ACLF is an unmet medical need,” said Rajiv Jalan, MD, professor of hepatology and honorary consultant in hepatology, University College London Hospitals, London, England.

These findings highlight “the inadequacy of current transplant allocation criteria for patients with ACLF 2 and 3,” which is leading to excess mortality on the wait list, he added.

Dr. Jalan presented the interim results at the European Association for the Study of the Liver (EASL) Congress 2024.

If confirmed in the full analysis, these results argue strongly for increasing access to liver transplantation and changing organ allocation for patients with ACLF 2 and 3, he said.
 

Organ Allocation Principally Based on MELD Scores

ACLF, which occurs in patients with cirrhosis and acutely decompensated liver disease admitted to hospital, carries a high, short-term risk for death. The risk for 28-day mortality for ACLF 2 and 3 is between 30% and 90% and characterized by multiorgan failure.

As seen in previous data, even patients on the transplant waiting list with a low Model for End-Stage Liver Disease (MELD) score have a risk for death between 20% and 30% if they are ACLF 2 and 3, Dr. Jalan said.

MELD scores do not consider the risk for death because of failure of extrahepatic organs, he added. Existing worldwide organ allocation systems are principally based on patient MELD scores or its variations; therefore, many patients die on the waiting list.

With this in mind, the CHANCE study aimed to compare 1-year graft and patient survival rates after liver transplantation in patients with ACLF 2 or 3 at the time of transplantation with patients with decompensated cirrhosis without ACLF and transplantation-free survival of patients with ACLF 2 or 3 not listed for liver transplantation.

The multicenter observational study comprised 66 liver transplant centers from 21 countries and over 500 investigators. Recruitment was closed after 1000 patients were enrolled.

Patients were aged 54-56 years, 31%-35% were women, 48%-70% had alcohol-related cirrhosis, and 19%-24% had metabolic dysfunction–associated steatohepatitis. MELD scores ranged from 25 to 36.

For the interim results, Dr. Jalan and colleagues assessed mortality on the waiting list and 3-month post–liver transplantation mortality.

Secondary endpoints included quality of life and cost of care.

Of the 823 patients in the study, they were grouped as follows: 376 patients with ACLF 2 or 3 listed for liver transplantation (group 1), 313 patients with ACLF 0 or 1 and MELD score > 20 listed for liver transplantation (group 2), and 134 patients with ACLF 2 or 3 not listed for liver transplantation (group 3).

Overall, patients in group 1 had very severe ACLF; 177 patients with ACLF 3 had three or more organ failures, Dr. Jalan noted.

“It is interesting to note that, in group 3, there is an overrepresentation of alcohol-related cirrhosis, and this might reflect a bias in transplantation,” he added.

Dr. Jalan highlighted geographical points of difference. Patients in the United States were younger, which could be important when interpreting results of post-transplantation outcomes. In Asia, the majority of the patients were men and primarily from India, where living donor transplantation is commonly performed. In Latin America, only 33% of study participants had alcohol-related cirrhosis in contrast to 67% of those in North America.

However, “comorbidities across the world were similar, and MELD scores were also similar,” Dr. Jalan said.
 

Death or Delisting

Between listing and transplantation, 28% of patients in group 1 either died or were delisted, compared with 16% of those in group 2. In group 3, 85% of patients who were not listed for transplantation in the first place died.

Similar to what has been seen in other studies, nearly 50% of patients with ACLF 3 but a MELD score < 25 on the wait list died or were delisted, Dr. Jalan pointed out, suggesting that these patients are disadvantaged under the current system of waiting list priority.

Geographically, deaths on the wait list were significantly higher in Latin America at 40% than in North America, Europe, and Asia at 20%, 18%, and 13%, respectively.

“This is likely due to low donation rates in Latin America,” Dr. Jalan said.

Turning to 3-month post-transplantation mortality, the rates in groups 1 and 2 were 9% and 7%, respectively.

“This demonstrates very nicely the clear benefit of transplant,” Dr. Jalan said. “The risk of death post transplant, even with ACLF 2 or 3, is not significantly different to those patients with decompensated cirrhosis.”

There was a slightly higher risk for death in patients with ACLF 3 than in those with ACLF 2 at 14% vs 7%, but “the risk of death in these patients if they don’t have transportation is 70%-80%,” he said.

Looking at 3-month post-transplantation mortality by continent, Dr. Jalan highlighted that Latin America showed 16% risk, compared with Asia, Europe, and North America that showed 12%, 7%, and 3% risk, respectively.

“This is probably multifactorial and likely to be influenced by time on the waiting list, quality of organs available, and patient demographics, among other factors,” Dr. Jalan said. When very sick people undergo transplantation, “there is a higher risk of death.”

The patients in this study have waited a long time, “which worsens their situation,” said Dr. Jalan, reinforcing his argument for changing the international organ allocation system to allow earlier access for these patients.
 

‘The Landscape of Organ Allocation Is Extremely Complex’

Comoderator Ana Lleo, MD, PhD, full professor of internal medicine and hepatology, Humanitas University, Milan, Italy, commented that “the number of patients included in this international study is significant,” and that the issue of mortality on the wait list is of great clinical interest.

“The landscape of organ allocation is extremely complex,” she added.

The system for liver transplantation considers a large number of clinical conditions with very diverse benefit profiles, she explained.

“While we would like to offer liver transplantation for all patients with any range of benefit, the current donations are not sufficient to cover the request,” Dr. Lleo said. “Therefore, prioritization remains key.”

The findings do illustrate the inadequacy of current transplantation allocation criteria for patients with ACLF 2 and 3, said Debbie Shawcross, MBBS, PhD, professor of hepatology and chronic liver failure, King’s College Hospital, London, England, who is also serving as vice-secretary of the EASL Governing Board.

However, “this must be balanced by the recognition that the global donor pool of organs available is a finite resource,” she said, echoing Dr. Lleo’s comments.

This calls for wider ethical discussions to avoid disadvantaging more stable, often younger patients with cirrhosis who are listed for transplantation, she added.

Dr. Jalan declared he is the inventor of Ornithine Phenylacetate, licensed by UCL to Mallinckrodt Pharma; a speaker and grant reviewer for Grifols Research Collaboration: Yaqrit; and the founder of Yaqrit, Hepyx, CyberLiver, and Gigabiome. Dr. Lleo declared that she does not have any conflicts relevant to this work but received lecture fees from Gilead, Advanz Pharma, Alfasigma, GSK, Incyte, Gore, AstraZeneca, and Ipsen and consulted for Advanz Pharma, AstraZeneca, Ipsen, GSK, and Dr Falk. Dr. Shawcross declared advisory board/consultancy for EnteroBiotix, Norgine, Satellite Bio, and MRN Health.

The findings do illustrate the inadequacy of current transplantation allocation criteria for patients with ACLF 2 and 3, said Debbie Shawcross, MBBS, PhD, professor of hepatology and chronic liver failure, King’s College Hospital, London, England, who is also serving as vice-secretary of the EASL Governing Board.

However, “this must be balanced by the recognition that the global donor pool of organs available is a finite resource,” she said, echoing Dr. Lleo’s comments.

This calls for wider ethical discussions to avoid disadvantaging more stable, often younger patients with cirrhosis who are listed for transplantation, she added.

MILAN — Survodutide, an investigational dual glucagon-like peptide 1 (GLP-1) and glucagon receptor agonist, led to “exceptional improvement in disease activity and fibrosis” in patients with metabolic dysfunction–associated steatohepatitis (MASH), according to phase 2 results presented here at the European Association for the Study of the Liver (EASL) Congress 2024.

The data were simultaneously published in The New England Journal of Medicine .

The primary endpoint data, reported earlier this year in a press release, showed that up to 83% of participants on survodutide showed a statistically significant improvement in MASH compared with those on placebo (18.2%) based on paired biopsy results.

In addition, 75% of patients treated with survodutide experienced resolution of MASH with no worsening of fibrosis compared with 15% of patients on placebo, and in patients with F2/F3 fibrosis, 64.5% achieved improvement in fibrosis without worsening of MASH, reported Arun J. Sanyal, MD, principal study investigator and director of the Virginia Commonwealth University (VCU) Stravitz-Sanyal Institute for Liver Disease and Metabolic Health, VCU School of Medicine, Richmond, Virginia.

American Association for the Study of Liver Diseases

What’s so amazing is that this “exceptional improvement” is after 48 weeks of therapy with a class of molecule that is already known to also have cardiometabolic benefits, Dr. Sanyal said in an interview.

“At the highest dose of survodutide [6.0 mg], two thirds of patients in whom we have biopsy data, at both the beginning and the end, actually showed fibrosis regression within 48 weeks,” he said. “This is pretty dramatic.”
 

Efficacy and Safety of Survodutide

A total of 293 participants with biopsy-confirmed MASH and fibrosis stages F1-F3 were randomly assigned (1:1:1:1) to receive once-weekly subcutaneous injections of survodutide 2.4 mg (n = 73), 4.8 mg (n = 72), or 6.0 mg (n = 74) or placebo (n = 74).

Around half of study participants were women, with mean age around 50 years and a body mass index around 35 kg/m². Overall, 26%-30% had type 2 diabetes, 24%-36% had F2 fibrosis, and 23%-30% had F3 fibrosis. The total Nonalcoholic Fatty Liver Disease Activity Score was 5.2.

After completing a 24-week rapid-dose-escalation phase, participants followed a 24-week maintenance phase. Histologic improvement (reduction) in MASH without worsening of fibrosis after 48 weeks of treatment comprised the primary endpoint, whereas a reduction in liver fat content by at least 30% and biopsy-assessed reduction in fibrosis by at least one stage were among the secondary endpoints.

The main analyses of the trial were based on two treatment sets: Actual treatment (the actual dose received at the start of the maintenance phase; per protocol) and planned treatment (the maintenance dose assigned to participants at randomization). Dr. Sanyal mainly reported results based on actual treatment, which were used for the primary analysis.

The overall primary endpoint data, including nonresponders, showed a 47% improvement in MASH in the 2.4-mg treatment group, 62% in the 4.8 mg group, and 43% in the 6.0-mg group compared with 13.5% in the placebo group (P < .001).

In addition, 50% of patients on 2.4- and 6-mg doses experienced a statistically significant improvement in fibrosis (F1-F3) without worsening of MASH. In patients with F2/F3 fibrosis, 64.5% of participants in the 6-mg survodutide group showed improvement vs 25.9% in the placebo group.

Reduction in liver fat by at least 30% was achieved by up to 87% in the 6-mg group according to MRI-estimated proton density fat fraction; when nonresponders were included, the percentage was 76.9% of the 6-mg group. Other outcomes included weight loss and reductions in A1c.

The results did not differ markedly between doses, which “is really exciting news,” Dr. Sanyal said.

Patients who are intolerant of the highest dose can switch to a lower dose without a big loss of efficacy, he said, adding that even the low dose was sufficient to get near maximal glucagon effect.

Adverse events were similar between survodutide and placebo, except for gastrointestinal events, including nausea, diarrhea, and vomiting. The occurrence of serious adverse events also was similar between survodutide and placebo.

Discontinuation due to adverse events was 20% across all the survodutide groups (with 16% due to gastrointestinal events) vs 3% in the placebo group.
 

Dual Agonist vs Monoagonist Therapy

The dual agonist approach may confer clinical advantages over GLP-1 receptor monoagonist pharmacotherapies for MASH.

“GLP has no receptors in the liver, so all its effects are mediated outside the liver, particularly for weight loss and improvement in metabolic status, increase in insulin secretion and sensitivity, and overall systemic glycemia,” Dr. Sanyal explained.

“People with established fibrosis take longer to respond in terms of downstream liver scarring with extrahepatic changes alone,” he added.

With “glucagon directly targeting the liver, we believe this reduces oxidative stress and possibly stimulates FGF-21 secretion [liver-derived factor that regulates lipid and glucose metabolism] in the liver, so there are likely multiple mechanisms driving the antifibrogenic benefits,” Dr. Sanyal said.

In comparison, the study authors highlighted that data on the GLP-1 receptor monoagonist semaglutide suggest a significantly higher proportion of patients on semaglutide achieve MASH resolution than those on placebo but that it does not result in “a significantly higher percentage of patients with improvement in fibrosis stage.

“It might be that it takes longer to get an effect in the liver with semaglutide,” Dr. Sanyal said.

By year-end, we’ll know how the GLP-1 alone approach (eg, semaglutide) and the dual agonist approach work, and we’ll eventually have data on triple agonists, Dr. Sanyal added.
 

The Burden of Liver Disease

Comoderator Debbie Shawcross, MBBS, PhD, professor of hepatology and chronic liver failure, King’s College, London, England, remarked on the importance of new drugs, including survodutide, in reducing the burden of steatotic liver disease.

Approximately one third of the world’s population and between 7% and 9% of children have steatotic liver disease, she noted. The buildup of fat causes inflammation and scarring of the liver, which may then progress to liver cirrhosis and primary liver cancers.

Survodutide offers much hope “as a drug that will reduce both liver inflammation and scarring, while also providing the benefit of improved diabetic control,” Dr. Shawcross said.

Reflecting on the dual agonism, she said that both the glucagon and GLP-1 receptors are critical to controlling metabolic functions.

Survodutide is currently being investigated in five phase 3 studies for people living with overweight and obesity, both of which are associated with MASH. There is also a trial looking at people with overweight/obesity with confirmed or presumed diagnosis of MASH, according to a company press release.

Dr. Sanyal reported grants, consultancy fees, and speaker fees from a wide range of companies working in the field of liver medicine. Dr. Shawcross reported no conflicts in relation to this drug and advisory board membership/consultancy for EnteroBiotix, Norgine, Satellite Bio, and MRN Health.

MILAN — Seladelpar, an investigational selective peroxisome proliferator-activated receptor delta agonist, achieves both biochemical and clinically meaningful improvements in pruritus and liver injury in patients with primary biliary cholangitis (PBC), both with and without compensated liver cirrhosis, according to two interim analyses of the ASSURE long-term extension study.

The first analysis of 337 patients with PBC, with and without cirrhosis, showed that treatment with seladelpar had a durable effect up to 2 years on cholestasis and markers of liver injury, as well as a sustained reduction in pruritus, Palak Trivedi, MD, associate professor at the National Institute for Health Research Birmingham Biomedical Research Centre, University of Birmingham, Birmingham, England, reported in a poster presented at the European Association for the Study of the Liver (EASL) Congress 2024.

The 2-year analysis also showed that seladelpar, a first-in-class, orally active agent, was safe and well tolerated in this patient population, he added.

These “results are consistent with the pivotal phase 3 RESPONSE study,” Dr. Trivedi noted. The RESPONSE study showed that seladelpar significantly improved liver biomarkers of disease activity and symptoms of pruritus at 12 months in patients with PBC who had an inadequate response or intolerance to ursodeoxycholic acid (UDCA), the standard of care, and had no history of hepatic decompensation. Patients with cirrhosis were allowed to enroll.

A total of 158 patients from the RESPONSE trial, both from the placebo and from the active treatment arm, were rolled over into the ASSURE trial. Another subset of 179 patients were drawn from prior seladelpar placebo-controlled studies (referred to as “legacy studies”), including the ENHANCE study. All participants in the current analysis received 10 mg of seladelpar, once daily, for up to 155 weeks.

Of the participants from the legacy studies, 99 completed 24 months of treatment with seladelpar, and 164 completed 12 months of treatment. In the 24-month treatment group, 70% met the composite response endpoint, which included alkaline phosphatase (ALP) levels below 1.67 times the upper limit of normal, a decrease in ALP levels of at least 15%, and total bilirubin levels at or below the upper limit of normal, according to a press release of the study findings. In addition, 42% of these participants achieved ALP normalization at 24 months, a marker of liver disease progression. In the 12-month treatment group, 73% achieved the clinically meaningful composite response endpoint, with 42% experiencing ALP normalization.

For patients rolled over from RESPONSE, 102 received 18 months of treatment with seladelpar, and 29 received 24 months of treatment. A total of 62% of patients in the 18-month group achieved the composite endpoint, and 33% achieved ALP normalization, while 72% of the 24-month group reached the composite endpoint, and 17% had ALP normalization.

Of patients who had received a placebo in the RESPONSE trial and went on to receive treatment with seladelpar, 75% achieved the composite endpoint, 27% had ALP normalization at 6 months, and 94% achieved the composite endpoint and 50% reached ALP normalization at 12 months.

Key secondary endpoints included ALP normalization and changes in liver enzymes (ALP, total bilirubin, gamma-glutamyl transferase [GGT], alanine transaminase [ALT], and aspartate aminotransferase [AST]).
 

Pruritus Relief Important for Quality of Life

Among study participants who reported a four or more at baseline on the numerical rating scale (NRS) for pruritus, legacy patients at 12 months and 24 months of treatment reported a mean reduction of 3.8 and 3.1, respectively. Participants from RESPONSE also reported a mean reduction of 3.8.

This level of reduction in NRS is “considered clinically significant” and takes patients from a level of moderate to severe itching down to mild, said Carrie Frenette, MD, executive director, Global Medical Affairs, Liver Diseases, Gilead Sciences, Foster City, California, and a former hepatologist of 20 years with a special interest in liver transplantation.

This “is a huge benefit in quality of life for these patients,” Dr. Frenette said in an interview.

Dr. Frenette also noted that UDCA, the current first-line treatment for PBC, is inadequate in up to 40% of patients, and second-line treatments, notably obeticholic acid, can cause itching.

European Society for Organ Transplantation

Eleonora De Martin, MD, transplant hepatologist at Centre Hépato-Biliaire, Paul Brousse Hospital, Paris, France, who comoderated the session, pointed out that PBC is a complex disease.

“We need both disease control and symptom control, and they’re not always compatible,” she said. “Sometimes you can control the disease but not the symptoms, and symptomatic control is so important,” especially with pruritus.
 

Patients With PBC and Cirrhosis

A separate analysis from ASSURE looked at a subset of 17 patients with PBC and cirrhosis who completed 24 months of treatment. The findings were presented by Stuart Gordon, MD, professor of medicine, Wayne State University School of Medicine, and hepatologist at Henry Ford Hospital, both in Detroit.

In this analysis, the mean patient age was 60.8 years, 91.4% were female, 88.6% were Child-Pugh A, and 22.9% had portal hypertension, while the mean baseline liver stiffness by FibroScan was 19.9 kPa.

Baseline biochemical measures were mean ALP of 245.4 U/L, mean total bilirubin of 0.995 mg/dL, mean GGT of 216.1 U/L, and mean ALT of 36.6 U/L.

A total of 11 participants (65%) met the composite endpoint at 24 months, with ALP normalization in 4 patients (24%). The overall mean percent change from baseline in ALP was approximately −30% and in total bilirubin was around −14%. Other changes in biochemical markers included reductions from baseline in GGT and ALT of approximately −30% and −10%, respectively. No change was observed in AST.

While 80% of patients with cirrhosis “had an adverse event of some form,” there were no treatment-related serious adverse events.

“It’s interesting to see results in these patients who have advanced disease and are cirrhotic because it might stabilize disease or even provide improvement,” Dr. De Martin commented. “However, the numbers in the study are very small, so it’s hard to draw firm conclusions yet, but it is a first step in showing that this drug is safe.”

Seladelpar is an “important step forward in PBC because we’ve been stuck with ursodeoxycholic acid for so many years,” Dr. De Martin added. “We’ve seen in liver disease with other etiologies that sometimes just one drug can make a difference, and you can change the natural history of the disease.”

Dr. Frenette is an employee and stockholder of Gilead Sciences. Dr. Gordon declared grants and support from AbbVie, Arbutus, CymaBay, Cour Pharmaceuticals, GlaxoSmithKline (GSK), Ipsen, and Mirum Pharmaceuticals; and advisory board activity from CymaBay, GSK, and Ipsen Pharmaceuticals. Dr. De Martin had no disclosures of relevance to seladelpar but has received speaker fees from other companies, including GSK, Ipsen, and Astellas.

In the 24-month treatment group, 70% met the composite response endpoint, which included alkaline phosphatase (ALP) levels below 1.67 times the upper limit of normal, a decrease in ALP levels of at least 15%, and total bilirubin levels at or below the upper limit of normal, according to a press release of the study findings. In addition, 42% of these participants achieved ALP normalization at 24 months, a marker of liver disease progression. In the 12-month treatment group, 73% achieved the clinically meaningful composite response endpoint, with 42% experiencing ALP normalization.

For patients rolled over from RESPONSE, 102 received 18 months of treatment with seladelpar, and 29 received 24 months of treatment. A total of 62% of patients in the 18-month group achieved the composite endpoint, and 33% achieved ALP normalization, while 72% of the 24-month group reached the composite endpoint, and 17% had ALP normalization.

Of patients who had received a placebo in the RESPONSE trial and went on to receive treatment with seladelpar, 75% achieved the composite endpoint, 27% had ALP normalization at 6 months, and 94% achieved the composite endpoint and 50% reached ALP normalization at 12 months.

Key secondary endpoints included ALP normalization and changes in liver enzymes (ALP, total bilirubin, gamma-glutamyl transferase [GGT], alanine transaminase [ALT], and aspartate aminotransferase [AST]).
 

Pruritus Relief Important for Quality of Life

Among study participants who reported a four or more at baseline on the numerical rating scale (NRS) for pruritus, legacy patients at 12 months and 24 months of treatment reported a mean reduction of 3.8 and 3.1, respectively. Participants from RESPONSE also reported a mean reduction of 3.8.

This level of reduction in NRS is “considered clinically significant” and takes patients from a level of moderate to severe itching down to mild, said Carrie Frenette, MD, executive director, Global Medical Affairs, Liver Diseases, Gilead Sciences, Foster City, California, and a former hepatologist of 20 years with a special interest in liver transplantation.

This “is a huge benefit in quality of life for these patients,” Dr. Frenette said in an interview.

Dr. Frenette also noted that UDCA, the current first-line treatment for PBC, is inadequate in up to 40% of patients, and second-line treatments, notably obeticholic acid, can cause itching.

European Society for Organ Transplantation

Eleonora De Martin, MD, transplant hepatologist at Centre Hépato-Biliaire, Paul Brousse Hospital, Paris, France, who comoderated the session, pointed out that PBC is a complex disease.

“We need both disease control and symptom control, and they’re not always compatible,” she said. “Sometimes you can control the disease but not the symptoms, and symptomatic control is so important,” especially with pruritus.
 

Patients With PBC and Cirrhosis

A separate analysis from ASSURE looked at a subset of 17 patients with PBC and cirrhosis who completed 24 months of treatment. The findings were presented by Stuart Gordon, MD, professor of medicine, Wayne State University School of Medicine, and hepatologist at Henry Ford Hospital, both in Detroit.

In this analysis, the mean patient age was 60.8 years, 91.4% were female, 88.6% were Child-Pugh A, and 22.9% had portal hypertension, while the mean baseline liver stiffness by FibroScan was 19.9 kPa.

Baseline biochemical measures were mean ALP of 245.4 U/L, mean total bilirubin of 0.995 mg/dL, mean GGT of 216.1 U/L, and mean ALT of 36.6 U/L.

A total of 11 participants (65%) met the composite endpoint at 24 months, with ALP normalization in 4 patients (24%). The overall mean percent change from baseline in ALP was approximately −30% and in total bilirubin was around −14%. Other changes in biochemical markers included reductions from baseline in GGT and ALT of approximately −30% and −10%, respectively. No change was observed in AST.

While 80% of patients with cirrhosis “had an adverse event of some form,” there were no treatment-related serious adverse events.

“It’s interesting to see results in these patients who have advanced disease and are cirrhotic because it might stabilize disease or even provide improvement,” Dr. De Martin commented. “However, the numbers in the study are very small, so it’s hard to draw firm conclusions yet, but it is a first step in showing that this drug is safe.”

Seladelpar is an “important step forward in PBC because we’ve been stuck with ursodeoxycholic acid for so many years,” Dr. De Martin added. “We’ve seen in liver disease with other etiologies that sometimes just one drug can make a difference, and you can change the natural history of the disease.”

MILAN — Seladelpar, an investigational selective peroxisome proliferator-activated receptor delta agonist, achieves both biochemical and clinically meaningful improvements in pruritus and liver injury in patients with primary biliary cholangitis (PBC), both with and without compensated liver cirrhosis, according to two interim analyses of the ASSURE long-term extension study.

The first analysis of 337 patients with PBC, with and without cirrhosis, showed that treatment with seladelpar had a durable effect up to 2 years on cholestasis and markers of liver injury, as well as a sustained reduction in pruritus, Palak Trivedi, MD, associate professor at the National Institute for Health Research Birmingham Biomedical Research Centre, University of Birmingham, Birmingham, England, reported in a poster presented at the European Association for the Study of the Liver (EASL) Congress 2024.

The 2-year analysis also showed that seladelpar, a first-in-class, orally active agent, was safe and well tolerated in this patient population, he added.

These “results are consistent with the pivotal phase 3 RESPONSE study,” Dr. Trivedi noted. The RESPONSE study showed that seladelpar significantly improved liver biomarkers of disease activity and symptoms of pruritus at 12 months in patients with PBC who had an inadequate response or intolerance to ursodeoxycholic acid (UDCA), the standard of care, and had no history of hepatic decompensation. Patients with cirrhosis were allowed to enroll.

A total of 158 patients from the RESPONSE trial, both from the placebo and from the active treatment arm, were rolled over into the ASSURE trial. Another subset of 179 patients were drawn from prior seladelpar placebo-controlled studies (referred to as “legacy studies”), including the ENHANCE study. All participants in the current analysis received 10 mg of seladelpar, once daily, for up to 155 weeks.

Of the participants from the legacy studies, 99 completed 24 months of treatment with seladelpar, and 164 completed 12 months of treatment. In the 24-month treatment group, 70% met the composite response endpoint, which included alkaline phosphatase (ALP) levels below 1.67 times the upper limit of normal, a decrease in ALP levels of at least 15%, and total bilirubin levels at or below the upper limit of normal, according to a press release of the study findings. In addition, 42% of these participants achieved ALP normalization at 24 months, a marker of liver disease progression. In the 12-month treatment group, 73% achieved the clinically meaningful composite response endpoint, with 42% experiencing ALP normalization.

For patients rolled over from RESPONSE, 102 received 18 months of treatment with seladelpar, and 29 received 24 months of treatment. A total of 62% of patients in the 18-month group achieved the composite endpoint, and 33% achieved ALP normalization, while 72% of the 24-month group reached the composite endpoint, and 17% had ALP normalization.

Of patients who had received a placebo in the RESPONSE trial and went on to receive treatment with seladelpar, 75% achieved the composite endpoint, 27% had ALP normalization at 6 months, and 94% achieved the composite endpoint and 50% reached ALP normalization at 12 months.

MILAN — Tirzepatide, a glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) receptor agonist, was more effective than was placebo in the resolution of metabolic dysfunction–associated steatohepatitis (MASH) and in the improvement of fibrosis, according to the results of the phase 2 SYNERGY-NASH trial.

Specifically, 44%-62% of participants with MASH and moderate or severe fibrosis treated with 5-15 mg of tirzepatide achieved MASH resolution without worsening of fibrosis compared with 10% on placebo; 51%-55% of those on tirzepatide achieved at least one stage of fibrosis improvement without worsening of MASH compared with 30% on placebo. Tirzepatide also led to weight loss.

The study (Abstract LBO-001) was presented at the European Association for the Study of the Liver (EASL) Congress 2024 by Rohit Loomba, MD, professor of medicine, NAFLD Research Center, University of California at San Diego in La Jolla, and published simultaneously in The New England Journal of Medicine. 

“The results are clinically meaningful,” Dr. Loomba said in an interview. 

University of California, San Diego

Both of the endpoints — improvements in MASH resolution and fibrosis — are considered approvable endpoints for MASH therapeutic development, and therefore, increase the likelihood of success of using such a strategy in a phase 3 setting, Dr. Loomba said.
 

MASH Resolution, No Worsening of Fibrosis

The dose-finding, multicenter, double-blind, placebo-controlled trial randomly assigned a total of 190 participants to receive once-weekly subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 52 weeks. Participants had biopsy-confirmed MASH and stage F2 or F3 (moderate or severe) fibrosis. 

Overall, approximately 42% of participants had F2 fibrosis and over 57% had F3 fibrosis. The proportion of F3 fibrosis was numerically higher in the placebo (64.6%) and 5-mg tirzepatide (63.8%) groups. 

The mean age of the study cohort was 54 years; 57% were female, 86% were White, and 36% were Hispanic; the mean body mass index was 36; 58% had type 2 diabetes; and A1c was 6.5. NAFLD activity score (NAS) was 5.3. Baseline noninvasive test results were consistent with the study population of MASH with F2/F3 fibrosis and NAS ≥ 4. 

The primary endpoint was resolution of MASH without worsening of fibrosis at 52 weeks, and the key secondary endpoint was an improvement (decrease) of at least one fibrosis stage without worsening of MASH. Other secondary endpoints included a ≥ 2-point decrease in NAS with ≤ 1-point decrease in two or more NAS components.

A total of 157 participants (83%) underwent liver biopsies at week 52, providing results for the current analysis. 

Among tirzepatide-treated patients, 43.6% in the 5-mg group, 55.5% in the 10-mg group, and 62.4% in the 15-mg group met the criteria for resolution of MASH without worsening of fibrosis compared with  10% in the placebo group (P < .001 for all three comparisons). 

Fibrosis improved by at least one stage without worsening of MASH in 54.9% of participants in the 5-mg tirzepatide group, 51.3% in the 10-mg tirzepatide group, and 51.0% in the 15-mg tirzepatide group compared with 29.7% in the placebo group (P < .001 for all risk differences with placebo). 

Changes in NAS and subscores for the individual components of NAS, including steatosis, lobular inflammation, and hepatocellular ballooning, were also seen in participants on tirzepatide. 

The researchers used a composite endpoint of a ≥ 2-point decrease in NAS with a ≥ 1-point decrease in at least two NAS components. Of the tirzepatide-treated groups, 71.7%,78.3%, and 76.6% in the 5-mg, 10-mg, and 15-mg groups, respectively, met this endpoint compared with 36.7% in placebo. 

Imaging of liver fat with MRI-based proton density fat fraction (MRI-PDFF) showed reductions from baseline of -45.7, -41.3, -57.0 in participants on 5-mg, 10-mg, and 15-mg tirzepatide, respectively. Differences from placebo were all statistically significant. 

Percentage of body weight change from baseline was -10.7%, -13.3%, and -15.6% in the 5-mg, 10-mg, and 15-mg tirzepatide groups, respectively, compared with weight loss of -0.8% in the placebo group. 

“Tirzepatide led to significant weight loss in both patients with diabetes and those without diabetes,” reported Dr. Loomba. 

There were more adverse events in patients on tirzepatide (92.3%) compared with patients on placebo (83.3%). 

“The most common adverse events were gastrointestinal in nature, with 96% of them mild to moderate in severity,” said Dr. Loomba. “Discontinuations occurred in 4.2% of participants, which was similar between patients on tirzepatide and those on placebo.”

He pointed out that the safety profile of tirzepatide in a MASH population “was generally similar to that observed in the phase 3 trials of type 2 diabetes and obesity.”

Incidence of serious adverse events was also similar at 6.3% for participants on tirzepatide vs 6.2% for those on placebo; 2.8% on tirzepatide and 4.2% on placebo progressed to cirrhosis. There was no evidence of drug-induced liver injury. 
 

‘Convincing Results’

Commenting on the study, co-moderator Sven Francque, MD, hepatologist and head of department at the University Hospital of Antwerp, Belgium, said that the study was in a relatively “severe” patient population, which was one of its strengths. 

“These are convincing results in terms of MASH resolution, showing a strong response and dose-dependence,” he said.
