FDA Approves First Drug for MASH
, along with diet and exercise.
Resmetirom is a once-daily, oral thyroid hormone receptor beta-selective agonist. The FDA granted the drug breakthrough therapy designation and priority review.
The approval is based on the phase 3 MAESTRO-NASH trial, in which resmetirom was superior to placebo at achieving resolution of nonalcoholic steatohepatitis (NASH) and improving liver fibrosis in both 80-mg and 100-mg doses.
The trial used the earlier nomenclature of NASH and nonalcoholic fatty liver disease (NAFLD). An international consensus group has since changed these terms to MASH and metabolic dysfunction–associated steatotic liver disease (MASLD), respectively. (Note that the terms NASH and NAFLD will be used to discuss the trial results in this article to align with the trial’s original language.)
The results were published online February 6 in The New England Journal of Medicine.
“The approval of the first medication for NASH is a true game-changer for healthcare providers, the research community and, most importantly, patients living with this serious liver condition,” lead MAESTRO-NASH investigator Stephen Harrison, MD, gastroenterologist, hepatologist, and chairman of Pinnacle Clinical Research and Summit Clinical Research, San Antonio, Texas, said in a news release. 
“Based on the robust efficacy and safety data generated in two large Phase 3 MAESTRO studies, I believe Rezdiffra will become the foundational therapy for patients with NASH with moderate to advanced liver fibrosis. Importantly, we continue to study Rezdiffra to determine if the positive results observed in the MAESTRO studies will lead to reduced risk of progression to cirrhosis, liver failure, need for liver transplant and premature mortality,” Dr. Harrison added.
Addressing an Unmet Need
MASH is a progressive liver disease and the leading cause of liver-related mortality. The disease affects an estimated 1.5 million adults in the United States, of which, roughly 525,000 have MASH with significant fibrosis. Until now, there was no FDA-approved medication.
In the ongoing MAESTRO-NASH, 996 adults with biopsy-confirmed NASH and significant stage 2-3 fibrosis were randomly assigned to receive oral once-daily resmetirom (80 mg or 100 mg) or placebo.
Patients were followed for 52 weeks, at which point, they were assessed for the dual primary endpoints of NASH resolution (including a reduction in the NAFLD activity score by ≥ 2 points) with no worsening of fibrosis and an improvement (reduction) in fibrosis by at least one stage with no worsening of the NAFLD activity score.
Patients receiving resmetirom had a significant improvement across both doses and both primary endpoints.
At 52 weeks, NASH resolution with no worsening of fibrosis was achieved in 25.9% and 29.9% of the patients in the 80-mg and 100-mg groups, respectively, compared with 9.7% on placebo.
Fibrosis improved by at least one stage with no worsening of the NAFLD activity score in 24.2% and 25.9% of patients in the 80-mg and 100-mg groups, respectively, compared with 14.2% on placebo.
The trial also met multiple secondary endpoints, including statistically significant reduction from baseline in liver enzymes (alanine transaminase, aspartate aminotransferase, and gamma-glutamyl transferase) and low-density lipoprotein cholesterol with resmetirom compared with placebo.
Improvement in fibrosis biomarkers and relevant imaging tests were also observed in resmetirom treatment groups compared with placebo.
The most common adverse events included diarrhea and nausea, which typically began early in treatment and were mild to moderate in severity. Pruritus, abdominal pain, vomiting, constipation, and dizziness were also reported.
Resmetirom is expected to be available to patients in the United States in April and will be distributed through a limited specialty pharmacy network.
Full prescribing information is available online. Prescribing information does not include a liver biopsy requirement for diagnosis.

Semaglutide Curbs MASLD Severity in People Living With HIV
Semaglutide improved metabolic dysfunction–associated steatotic liver disease (MASLD) among people living with HIV, and in some cases resolved it completely, according to results from the SLIM LIVER study presented by the AIDS Clinical Trials Group (ACTG) at this year’s Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver.
Furthermore, although muscle volume decreased with weight loss, participants did not experience significant changes in muscle quality or physical function.
‘A First’
SLIM LIVER is the first study evaluating semaglutide as a treatment of MASLD among people living with HIV.
The phase 2b, single-arm pilot study enrolled adults living with HIV who were virally suppressed and had central adiposity, insulin resistance or prediabetes, and steatotic liver disease.
Participants self-injected semaglutide weekly at increasing doses until they reached a 1-mg dose at week 4. At 24 weeks, the study team assessed changes in participants’ intra-hepatic triglyceride content using magnetic resonance imaging-proton density fat fraction.
The primary analysis results from SLIM LIVER were reported in an oral presentation, “Semaglutide Reduces Metabolic-Associated Steatotic Liver Disease in People With HIV: The SLIM LIVER Study,” on March 5 by Jordan E. Lake, MD, MSc, of UTHealth Houston.
A subgroup analysis of the study was provided in a poster, “Effects of Semaglutide on Muscle Structure and Function in the SLIM LIVER Study,” presented on March 4 by Grace L. Ditzenberger, PT, DPT, of the University of Colorado Anschutz Medical Campus in Aurora.
In the primary analysis, the median age of the 49 participants was 52 years, 43% were women (cisgender and transgender), the mean body mass index was 35, 39% were Hispanic and 33% were Black/African American, and 82% were taking antiretroviral therapy that included an integrase inhibitor.
Liver fat was reduced by an average of 31%, with 29% of participants experiencing a complete resolution (5% or less liver fat) of MASLD. They also experienced weight loss, reduced fasting blood glucose, and reduced fasting triglycerides, consistent with effects observed in studies of semaglutide in people without HIV.
The sub-analysis of the 46 participants for whom muscle measurements were available showed that muscle volume (measured in the psoas) decreased but with no significant change in physical function.
Semaglutide was generally well tolerated, with an adverse event profile similar to that seen in individuals without HIV.
The most common adverse events were gastrointestinal (ie, nausea, diarrhea, vomiting, and abdominal pain). Two participants experienced more significant adverse events possibly related to semaglutide but were able to continue in the study.
All participants completed the full 24 weeks of therapy at the originally prescribed dose.
Potential Impact
“Even at the low dose of 1 mg every week, most participants lost significant weight, and weight loss was closely associated with improvements in MASLD,” Dr. Lake said. “Additional research will assess the secondary effects of semaglutide on systemic inflammation and metabolism and determine whether semaglutide may have unique risks or benefits for people living with HIV.”
“These findings have the potential to have a significant impact on the health and quality of life of people living with HIV,” added ACTG Chair Judith Currier, MD, MSc, University of California Los Angeles.
The SLIM LIVER study was sponsored by the US National Institute of Allergy and Infectious Diseases (NIAID), with additional funding from UTHealth Houston McGovern School of Medicine. ACTG is a clinical trials network focused on HIV and other infectious diseases, funded by NIAID and collaborating institutes of the US National Institutes of Health.
No conflicts of interest were reported.

FROM CROI 2024
Seladelpar Could ‘Raise the Bar’ in Primary Biliary Cholangitis Treatment
, according to the full results of the RESPONSE phase 3 study.
“At a dose of 10 mg daily, 1 in 4 patients normalize their alkaline phosphatase level,” chief investigator Gideon Hirschfield, PhD, BM BChir, with the Toronto Center for Liver Disease at Toronto General Hospital, Toronto, Ontario, Canada, said in an interview.
The study data are “genuinely exciting...and support the potential for seladelpar to raise the bar in PBC treatment,” Dr. Hirschfield added in a news release.
Seladelpar is being developed by CymaBay Therapeutics, which funded the study.
The results were published online in The New England Journal of Medicine.
Topline data from the study were presented in November at The Liver Meeting 2023: American Association for the Study of Liver Diseases.
‘Unequivocal’ Progress
Up to 40% of patients with PBC have an inadequate response to first-line therapy with ursodeoxycholic acid (UDCA) and are at a high risk for disease progression. More than half of patients with the disease fail to respond to second-line therapy with obeticholic acid.
Seladelpar, and the dual PPAR-alpha and PPAR-delta agonist elafibranor, are an “unequivocal sign of progress, marking the arrival of a new era in which PBC treatment is expected to provide both biochemical benefits and amelioration of symptoms for patients,” David N. Assis, MD, with the Section of Digestive Diseases, Yale School of Medicine, New Haven, Connecticut, wrote in a linked editorial.
In the RESPONSE study, 193 patients with PBC who had an inadequate response to or a history of unacceptable side effects with UDCA were randomly allocated to either oral seladelpar 10 mg daily or placebo for 12 months. The vast majority (93.8%) continued UDCA as standard-of-care background therapy.
The primary endpoint was a biochemical response, which was 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, 61.7% of patients taking seladelpar met the primary endpoint vs 20% of patients taking placebo.
In addition, significantly more patients taking seladelpar than placebo had normalization of the ALP level (25% vs 0%). The average decrease in ALP from baseline was 42.4% in the seladelpar 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 seladelpar group compared with 6.5% and 11.4%, respectively, in the placebo group.
“In PBC, we use target endpoints, so the trial was not powered or able to show yet clinical outcomes because the pace of the disease is quite slow. But we believe that the normalization of liver tests and improvement in quality of life will change the disease trajectory over time,” Dr. Hirschfield said.
Significant Reduction in Pruritus
A key secondary endpoint was change in patient-reported pruritus.
At baseline, 38.3% of patients in the seladelpar group and 35.4% of those in the placebo group had moderate to severe pruritus, with a daily numerical rating scale (NRS) score of 4 or higher out of 10.
Among these patients, the reduction from baseline in the pruritus NRS score at month 6 was significantly greater with seladelpar than with placebo (change from baseline, −3.2 points vs −1.7 points). These improvements were sustained through 12 months.
Improvements on the 5-D Itch Scale in both the moderate to severe pruritus population and the overall population also favored seladelpar over placebo for itch relief, which had a positive impact on sleep. Similar results demonstrating reductions in itch and improvements in sleep were observed using the PBC-40 questionnaire.
Adverse events that led to discontinuation of seladelpar or placebo were rare, and there was no between-group difference in the incidence of serious adverse events.
“No worrisome adverse events affecting the muscles were observed, including among patients receiving statins. Certain gastrointestinal events — abdominal pain, abdominal distention, and nausea — were reported more frequently in the seladelpar group than in the placebo group,” the study authors wrote.
The most common adverse events that occurred in ≥ 5% of patients in either group were COVID-19 and pruritus. A greater percentage of patients treated with placebo reported pruritus (15.4% vs 4.7%) as an adverse event — a finding consistent with the positive effect of seladelpar on reducing pruritus.
The researchers noted that 96.4% of patients who participated in the RESPONSE trial chose to enroll in the extension trial to evaluate long-term safety and the side-effect profile of seladelpar.
Potential First-Line Treatment?
In Dr. Assis’ view, the RESPONSE trial, coupled with the recently reported ELATIVE trial of the dual PPAR-alpha and PPAR-delta agonist elafibranor in PBC, “cement the role of PPAR agonists as the preferred second-line treatment in primary biliary cholangitis.”
“The reduction in serum cholestatic markers and the safety profiles of elafibranor and seladelpar offer clear advantages beyond what was previously shown with obeticholic acid. These trials also cement a new treatment goal for primary biliary cholangitis in which a reduction in pruritus should be expected as part of anticholestatic treatment,” Dr. Assis wrote.
“The results of these trials suggest that the use of PPAR agonists in primary biliary cholangitis could improve treatment outcomes while also improving quality of life, which is a highly desirable alignment of clinician and patient goals,” Dr. Assis added.
Looking ahead, Dr. Hirschfield sees a potential role for seladelpar earlier in the course of PBC treatment, he said in an interview.
“Over time, the way we treat patients will not be to wait to fail. It will be treat to target and treat to success,” Dr. Hirschfield said.
Earlier this month, the US Food and Drug Administration accepted CymaBay Therapeutics’ new drug application for seladelpar for the treatment of PBC, including pruritus in adults without cirrhosis or with compensated cirrhosis (Child Pugh A) who fail to respond adequately or cannot tolerate UDCA. Seladelpar for PBC was granted breakthrough designation in October 2023.
The study was funded by CymaBay Therapeutics. Disclosures for authors and editorialist are available at NEJM.org.

These trials also cement a new treatment goal for primary biliary cholangitis in which a reduction in pruritus should be expected as part of anticholestatic treatment,” Dr. Assis wrote.
“The results of these trials suggest that the use of PPAR agonists in primary biliary cholangitis could improve treatment outcomes while also improving quality of life, which is a highly desirable alignment of clinician and patient goals,” Dr. Assis added.
Looking ahead, Dr. Hirschfield sees a potential role for seladelpar earlier in the course of PBC treatment, he said in an interview.
“Over time, the way we treat patients will not be to wait to fail. It will be treat to target and treat to success,” Dr. Hirschfield said.
Earlier this month, the US Food and Drug Administration accepted CymaBay Therapeutics’ new drug application for seladelpar for the treatment of PBC, including pruritus in adults without cirrhosis or with compensated cirrhosis (Child Pugh A) who fail to respond adequately or cannot tolerate UDCA. Seladelpar for PBC was granted breakthrough designation in October 2023.
The study was funded by CymaBay Therapeutics. Disclosures for authors and editorialist are available at NEJM.org.

, according to the full results of the RESPONSE phase 3 study.
“At a dose of 10 mg daily, 1 in 4 patients normalize their alkaline phosphatase level,” chief investigator Gideon Hirschfield, PhD, BM BChir, with the Toronto Center for Liver Disease at Toronto General Hospital, Toronto, Ontario, Canada, said in an interview.
The study data are “genuinely exciting...and support the potential for seladelpar to raise the bar in PBC treatment,” Dr. Hirschfield added in a news release.
Seladelpar is being developed by CymaBay Therapeutics, which funded the study.
The results were published online in The New England Journal of Medicine.
Topline data from the study were presented in November at The Liver Meeting 2023: American Association for the Study of Liver Diseases.
‘Unequivocal’ Progress
Up to 40% of patients with PBC have an inadequate response to first-line therapy with ursodeoxycholic acid (UDCA) and are at a high risk for disease progression. More than half of patients with the disease fail to respond to second-line therapy with obeticholic acid.
Seladelpar, and the dual PPAR-alpha and PPAR-delta agonist elafibranor, are an “unequivocal sign of progress, marking the arrival of a new era in which PBC treatment is expected to provide both biochemical benefits and amelioration of symptoms for patients,” David N. Assis, MD, with the Section of Digestive Diseases, Yale School of Medicine, New Haven, Connecticut, wrote in a linked editorial.
In the RESPONSE study, 193 patients with PBC who had an inadequate response to or a history of unacceptable side effects with UDCA were randomly allocated to either oral seladelpar 10 mg daily or placebo for 12 months. The vast majority (93.8%) continued UDCA as standard-of-care background therapy.
The primary endpoint was a biochemical response, which was 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, 61.7% of patients taking seladelpar met the primary endpoint vs 20% of patients taking placebo.
In addition, significantly more patients taking seladelpar than placebo had normalization of the ALP level (25% vs 0%). The average decrease in ALP from baseline was 42.4% in the seladelpar 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 seladelpar group compared with 6.5% and 11.4%, respectively, in the placebo group.
“In PBC, we use target endpoints, so the trial was not powered or able to show yet clinical outcomes because the pace of the disease is quite slow. But we believe that the normalization of liver tests and improvement in quality of life will change the disease trajectory over time,” Dr. Hirschfield said.
Significant Reduction in Pruritus
A key secondary endpoint was change in patient-reported pruritus.
At baseline, 38.3% of patients in the seladelpar group and 35.4% of those in the placebo group had moderate to severe pruritus, with a daily numerical rating scale (NRS) score of 4 or higher out of 10.
Among these patients, the reduction from baseline in the pruritus NRS score at month 6 was significantly greater with seladelpar than with placebo (change from baseline, −3.2 points vs −1.7 points). These improvements were sustained through 12 months.
Improvements on the 5-D Itch Scale in both the moderate to severe pruritus population and the overall population also favored seladelpar over placebo for itch relief, which had a positive impact on sleep. Similar results demonstrating reductions in itch and improvements in sleep were observed using the PBC-40 questionnaire.
Adverse events that led to discontinuation of seladelpar or placebo were rare, and there was no between-group difference in the incidence of serious adverse events.
“No worrisome adverse events affecting the muscles were observed, including among patients receiving statins. Certain gastrointestinal events — abdominal pain, abdominal distention, and nausea — were reported more frequently in the seladelpar group than in the placebo group,” the study authors wrote.
The most common adverse events that occurred in ≥ 5% of patients in either group were COVID-19 and pruritus. A greater percentage of patients treated with placebo reported pruritus (15.4% vs 4.7%) as an adverse event — a finding consistent with the positive effect of seladelpar on reducing pruritus.
The researchers noted that 96.4% of patients who participated in the RESPONSE trial chose to enroll in the extension trial to evaluate long-term safety and the side-effect profile of seladelpar.
Potential First-Line Treatment?
In Dr. Assis’ view, the RESPONSE trial, coupled with the recently reported ELATIVE trial of the dual PPAR-alpha and PPAR-delta agonist elafibranor in PBC, “cement the role of PPAR agonists as the preferred second-line treatment in primary biliary cholangitis.”
“The reduction in serum cholestatic markers and the safety profiles of elafibranor and seladelpar offer clear advantages beyond what was previously shown with obeticholic acid.

NEJM Study Highlights Resmetirom’s Efficacy in NASH With Liver Fibrosis
published in The New England Journal of Medicine.
Although certain findings from this trial were initially presented at the European Association for the Study of the Liver Congress 2023, the publication of the full peer-reviewed paper represents a potentially significant milestone in the management of NASH, a disease for which there is currently no approved pharmacologic treatment.
“Data for the first 1,050 patients from the MAESTRO-NASH trial, together with data from completed resmetirom trials, support the potential for resmetirom to provide benefit to patients with NASH and liver fibrosis,” wrote the authors, led by principal investigator Stephen Harrison, MD, chairman of Pinnacle Clinical Research and Summit Clinical Research in San Antonio, Texas.
The trial uses the earlier nomenclature of NASH and nonalcoholic fatty liver disease (NAFLD). An international consensus group has since changed these terms to metabolic dysfunction–associated steatohepatitis (MASH) and metabolic dysfunction–associated steatotic liver disease (MASLD), respectively.
A Closer Look at MAESTRO-NASH
Investigators enrolled 996 participants who were randomly assigned to receive placebo or resmetirom at 80 mg or 100 mg. Patients were followed for 52 weeks, at which point, they were assessed for the dual primary endpoints of NASH resolution (including a reduction in the NAFLD activity score by ≥ 2 points) with no worsening of fibrosis and an improvement (reduction) in fibrosis by at least one stage with no worsening of the NAFLD activity score.
They observed that patients receiving resmetirom had a significant improvement across both doses and both primary endpoints.
NASH resolution with no worsening of fibrosis was achieved in 25.9% and 29.9% of the patients in the 80-mg and 100-mg groups, respectively, vs 9.7% on placebo. Fibrosis improved by at least one stage with no worsening of the NAFLD activity score in 24.2% and 25.9% of patients in the increasing-dose groups, respectively, compared with 14.2% on placebo (P < .001 for both doses compared with placebo).
The effects with resmetirom were consistent across key subgroups, regardless of baseline fibrosis stage; baseline NAFLD activity score; or type 2 diabetes status, age, and sex.
“Multiple non-invasive tests for NASH, steatosis, and fibrosis (including blood biomarkers and imaging) showed a similar direction of effects favoring resmetirom treatment, which supports the findings for the primary end points,” Dr. Harrison and colleagues wrote.
The majority of patients with NASH also have diabetes. As a result, patients with NASH are known to have a high cardiovascular risk and mortality. However, MAESTRO-NASH investigators reported that compared with those receiving placebo, patients on resmetirom experienced reductions in levels of a broad range of atherogenic lipids and lipoproteins, including low-density lipoprotein (LDL) cholesterol, non–high-density lipoprotein cholesterol, triglycerides, apolipoprotein B, and lipoprotein(a). These findings were consistent with earlier studies of resmetirom.
From baseline to week 24, LDL cholesterol levels were reduced by -13.6% in the 80-mg and by -16.3% in the 100-mg resmetirom groups compared with 0.1% in the placebo group (P < .001).
More patients in the 100-mg group than in the 80-mg or placebo groups discontinued the trial due to adverse events (6.8% vs 1.8% and 2.2%, respectively). Diarrhea and nausea occurred more frequently in the resmetirom groups than in the placebo group. Serious adverse events occurred with similar incidences across the 100-mg, 80-mg, and placebo groups (12.7%, 10.9%, and 11.5%, respectively).
Although to date the MAESTRO-NASH trial lacks clinical outcomes, over its planned duration of 54 months, investigators will accrue data on liver-related outcomes, including progression to cirrhosis. Likewise, long-term safety data will become available with the trial’s completion.

Meta-Analysis Highlights Litany of MASLD-Associated Complications, Encouraging New Treatment Targets
, based on a large-scale meta-analysis of longitudinal data.
These findings emphasize the multisystemic nature of MASLD, suggesting that broader treatment targets are needed to reduce systemic events and end organ complications, reported lead author Kai En Chan, MBBS, of the National University of Singapore, and colleagues.
“[D]espite the substantial impact of MASLD, with direct medical costs estimated to reach $103 billion in the United States alone, a comprehensive umbrella meta-analysis of the longitudinal complications associated with MASLD has yet to be conducted,” the investigators wrote in Clinical Gastroenterology and Hepatology, noting that key outcomes associated with sex and disease severity have yet to be elucidated. “A comprehensive understanding of the spectrum of clinical complications associated with MASLD is thus crucial in developing effective disease management strategies and optimizing the allocation of limited healthcare resources.”
To this end, the investigators analyzed data from 129 studies reporting longitudinal risks of clinical outcomes among adults with MASLD. Assessed complications spanned a broad array of organ systems and pathologies. Cardiovascular and oncologic conditions predominated, while chronic kidney disease, liver-related outcomes, gallstone formation, dementia, and reflux esophagitis were also considered.
The analysis revealed significant associations between MASLD and — in ascending level of risk — chronic kidney disease (hazard ratio [HR], 1.38), cardiovascular diseases (HR, 1.43), cancer (HR, 1.54), prediabetes (HR, 1.69), hypertension (HR, 1.75), diabetes (HR, 2.56), and metabolic syndrome (HR, 2.57).
Across cardiovascular diseases, MASLD raised risk of hypertension the most, by 75%. Among cancer types, MASLD increased risk of hepatocellular carcinoma to the greatest degree, by more than fourfold.
No significant sex-specific differences in MASLD-associated risk were detected for cancer, chronic kidney disease, diabetes, or cardiovascular disease, although the investigators urged a cautious interpretation of these findings, since relevant data were scarce.
“It is imperative to understand that MASLD is a complex and multifaceted condition that requires a comprehensive approach to recognition and treatment beyond that of the hepatologist alone,” the investigators wrote.
They also suggested that the link between MASLD and cancer deserves particular attention.
“Although the mechanism by which MASLD gives rise to cardiovascular disease and diabetes has been thoroughly researched, the pathophysiology of MASLD leading to extrahepatic carcinogenesis is less well understood and has been postulated to be linked to chronic inflammation and dysregulation of the gut microbiome in MASLD,” they wrote.
Lastly, considering the multiprong association between MASLD and so many complications, the investigators recommended broader clinical metrics for measuring outcomes in patients with MASLD.
“With the synergistic increases of metabolic diseases globally, treatment targets should in turn act beyond the resolution of fibrosis but also to reduce systemic end organ complications,” they concluded.The investigators disclosed relationships with AbbVie, Echosens, Gilead Sciences, and others.
In a massive meta-analysis of 129 studies that included over 6 million participants, Chan and colleagues evaluated the associations of MASLD with incident hepatic and extrahepatic outcomes. They report numerous associations for MASLD with metabolic, cardiovascular, and renal events as well as with gastrointestinal, hepatobiliary, and other types of cancers.
The unimpeded pace of the obesity pandemic remains a steady driver of the rise in the burden of metabolic syndrome and its components, including MASLD. Thus, approaches to tackle the rising burden of metabolic diseases including MASLD should start with the root driver, obesity. It is also imperative to consider addressing the cardiometabolic milieu in any approach designed to specifically target MASLD/MASH. Lifestyle modifications that include weight loss, smoking cessation, and avoidance of alcohol use may help reduce risks of cardiovascular disease and cancer, the leading causes of death in patients with MASLD. Anticipated pharmacologic therapies for MASH should not only improve liver endpoints but also have a beneficial or, at minimum, neutral extrahepatic effects on coexisting cardiometabolic conditions.

Dueling Gut Bacteria Impact Chronic HBV Progression
, according to investigators.
While Ruminococcus gnavus promotes immune tolerance and therefore HBV persistence, Akkermansia muciniphila stimulates the immune system, promoting viral clearance, reported lead author Huey-Huey Chua, MD, of the National Taiwan University College of Medicine and Children’s Hospital, Taipei, and colleagues.
These findings could lead to new therapeutic strategies, such as administration of the secretory products of A. muciniphila, or provision of probiotics and prebiotics that tip the balance toward this more beneficial bacterium, the investigators wrote in Cellular and Molecular Gastroenterology and Hepatology.
Their study, which included data from both human patients and mouse models of CHB, was grounded in prior research showing a link between gut microbiota and the age-dependence of HBV immunity.
“Sterilization of the gut microbiota using antibiotics prevents adult mice from rapidly clearing HBV and restores the tolerance phenotype, implying that the gut microbiota may transmit signals to break liver tolerance and evoke rapid HBV clearance,” Dr. Chua and colleagues wrote. “We hypothesized that the wax and wane of gut microbiota signatures may determine the progression of CHB. We aimed to delineate what the pivotal bacteria are and how they manipulate the progression of CHB.”
They began by analyzing fecal samples from 102 patients with CHB either in the immune-tolerant (IT) or immune-active (IA) phase of infection.
R. gnavus was the most abundant species among IT patients, whereas A. muciniphila was most abundant among patients in the IA phase. Higher levels of A. muciniphila were also associated with early hepatitis B e-antigen (HBeAG) loss, HBeAG seroconversion, and flares of aminotransferase. A mouse model echoed these findings.
Further experiments with mouse models revealed that R. gnavus modulates bile acids to promote HBV persistence and prolongation of the IT course. In opposition, A. muciniphila removes cholesterol and secretes metabolites that inhibit growth and function of R. gnavus.
“These novel findings will certainly confer a groundbreaking impact on the future therapy of CHB,” Dr. Chua and colleagues wrote.
They went on to describe several therapeutic strategies worth further investigation.
“A key step to promote switching from the IT to IA phase is to lessen the richness of R. gnavus and bile acid bioconversion from cholesterol,” they wrote. The secretory products of A. muciniphila that successfully ameliorate the burden of R. gnavus outgrowth can be provided as useful means to induce anti-HBV efficacy. Also, the development of targeted probiotics or prebiotics that can modulate the gut microbiota composition to favor the beneficial effects of A. muciniphila while inhibiting the detrimental effects of R. gnavus may have translational value for CHB.”

The investigators disclosed no conflicts of interest.
Clinical observations have long indicated that chronic hepatitis B (CHB) patients with a prolonged immune-tolerant (IT) phase are at a higher risk of liver diseases, while those with an early transition to the immune-active (IA) phase are associated with a better clinical outcome. However, the underlying mechanisms remain unclear.
This study merits attention as it marks an important advancement in our understanding of how gut microbiota affects the immune response and, in turn, the progression of CHB, offering insights for potential A. muciniphila–based therapies. Nonetheless, the research is still in its infancy, and further studies, including longitudinal analysis to determine gut microbiota changes from IT to IA, are required. The prospect of A. muciniphila supplementation could be beneficial for CHB patients, warranting clinical trials. Continued research could lead to improved management and prevention of liver diseases in this patient population with CHB.

While Ruminococcus gnavus promotes immune tolerance and therefore HBV persistence, Akkermansia muciniphila stimulates the immune system, promoting viral clearance, reported lead author Huey-Huey Chua, MD, of the National Taiwan University College of Medicine and Children’s Hospital, Taipei, and colleagues.
These findings could lead to new therapeutic strategies, such as administration of the secretory products of A. muciniphila, or provision of probiotics and prebiotics that tip the balance toward this more beneficial bacterium, the investigators wrote in Cellular and Molecular Gastroenterology and Hepatology.
Their study, which included data from both human patients and mouse models of CHB, was grounded in prior research showing a link between gut microbiota and the age-dependence of HBV immunity.
“Sterilization of the gut microbiota using antibiotics prevents adult mice from rapidly clearing HBV and restores the tolerance phenotype, implying that the gut microbiota may transmit signals to break liver tolerance and evoke rapid HBV clearance,” Dr. Chua and colleagues wrote. “We hypothesized that the wax and wane of gut microbiota signatures may determine the progression of CHB. We aimed to delineate what the pivotal bacteria are and how they manipulate the progression of CHB.”

Iron Overload in Non-HFE Liver Disease: Not all Iron is Ready to Strike
Pathological iron overload with end-organ damage in hemochromatosis occurs in individuals who are homozygous for the major mutation C282Y. Phenotypic hemochromatosis occurs much less frequently in compound heterozygotes with one C282Y mutation and one H63D mutation. Iron overload can be confirmed by magnetic resonance imaging, which shows a loss of signal intensity in affected tissues and avoids the need for liver biopsy.
The serum ferritin level, an acute phase reactant, may be elevated for reasons other than iron overload, including infection and malignancy; in such cases, the iron saturation is usually normal. In patients with liver disease, iron overload is not restricted to patients with genetic hemochromatosis. In nonalcoholic fatty liver disease (NAFLD), up to one-third of patients have an elevated iron saturation (> 45%) and an elevated serum ferritin level. Iron accumulation in NAFLD can occur in hepatocytes, the reticuloendothelial system, or both. Deposition of iron in the reticuloendothelial system has been implicated in more severe liver disease (steatohepatitis and fibrosis) in NAFLD. Hepatic iron accumulation is also frequent in alcohol-associated liver disease. In chronic hepatitis B and C, accumulation of hepatic iron is also recognized.

New Guideline Offers Recommendations for Alcohol-Associated Liver Disease
according to a new clinical guideline from the American College of Gastroenterology.
In addition, health systems need to overcome barriers to treating alcohol use disorder (AUD) and commit to creating a multidisciplinary care model with behavioral interventions and pharmacotherapy for patients.
Experts were convened to develop these guidelines because it was “imperative to provide an up-to-date, evidence-based blueprint for how to care for patients, as well as guide prevention and research efforts in the field of ALD for the coming years,” said the first author, Loretta Jophlin, MD, PhD, assistant professor of medicine in gastroenterology, hepatology, and nutrition and medical director of liver transplantation at the University of Louisville in Kentucky.
“In recent years, perhaps fueled by the COVID-19 pandemic, alcohol use has been normalized in an increasing number of situations,” she said. “Drinking was normalized as a coping mechanism to deal with many of the sorrows we experienced during the pandemic, including loss of purposeful work and social isolation, and many more people are struggling with AUD. So many aspects of our culture have been inundated by the presence of alcohol use, and we need to work hard to denormalize this, first focusing on at-risk populations.”
The guideline was published in the January issue of the American Journal of Gastroenterology.
Updating ALD Recommendations
With ALD as the most common cause of advanced hepatic disease and a frequent indicator of eventual liver transplantation, the rising incidence of alcohol use during the past decade has led to rapid growth in ALD-related healthcare burdens, the guideline authors wrote.
In particular, those with ALD tend to present at an advanced stage and progress faster, which can lead to progressive fibrosis, cirrhosis, and hepatocellular carcinoma. This can include alcohol-associated hepatitis (AH), which often presents with a rapid onset or worsening of jaundice and can lead to acute or chronic liver failure.
To update the guideline, Dr. Jophlin and colleagues analyzed data based on a patient-intervention-comparison-outcome format, resulting in 34 key concepts or statements and 21 recommendations.
Among them, the authors recommended screening and treating AUD with the goal of helping patients who have not yet developed significant liver injury and preventing progression to advanced stages of ALD, particularly among at-risk groups who have had an increasing prevalence of severe AUD, including women, younger people, and Hispanic and American Indian patients.
“So many patients are still told to ‘stop drinking’ or ‘cut back’ but are provided no additional resources. Without offering referrals to treatment programs or pharmacologic therapies to assist in abstinence, many patients are not successful,” Dr. Jophlin said. “We hope these guidelines empower providers to consider selected [Food and Drug Administration]-approved medications, well-studied off-label therapies, and nonpharmacologic interventions to aid their patients’ journeys to abstinence and hopefully avert the progression of ALD.”
In addition, the guidelines provide recommendations for AH treatment. In patients with severe AH, the authors offered strong recommendations against the use of pentoxifylline and prophylactic antibiotics, and in support of corticosteroid therapy and intravenous N-acetyl cysteine as an adjuvant to corticosteroids.
Liver transplantation, which may be recommended for carefully selected patients, is being performed at many centers but remains relatively controversial, Dr. Jophlin said.
“Questions remain about ideal patient selection as center practices vary considerably, yet we have started to realize the impacts of relapse after transplantation,” she said. “The guidelines highlight the knowns and unknowns in this area and will hopefully serve as a catalyst for the dissemination of centers’ experiences and the development of a universal set of ethically sound, evidence-based guidelines to be used by all transplant centers.”
Policy Implications
Dr. Jophlin and colleagues noted the importance of policy aimed at alcohol use reduction, multidisciplinary care for AUD and ALD, and additional research around severe AH.
“As a practicing transplant hepatologist and medical director of a liver transplant program in the heart of Bourbon country, I am a part of just one healthcare team experiencing ALD, particularly AH, as a mass casualty event. Healthcare teams are fighting an unrelenting fire that the alcohol industry is pouring gasoline on,” Dr. Jophlin said. “It is imperative that healthcare providers have a voice in the policies that shape this preventable disease. We hope these guidelines inspire practitioners to explore our influence on how alcohol is regulated, marketed, and distributed.”
Additional interventions and public policy considerations could help reduce alcohol-related morbidity and mortality at a moment when the characteristics of those who present with AUD appear to be evolving.
“The typical person I’m seeing now is not someone who has been drinking heavily for decades. Rather, it’s a young person who has been drinking heavily for many months or a couple of years,” said James Burton, MD, a professor of medicine at the University of Colorado School of Medicine and medical director of liver transplantation at the University of Colorado Hospital’s Anschutz Medical Campus in Aurora.
Dr. Burton, who wasn’t involved with the guideline, noted it’s become more common for people to drink multiple alcoholic drinks per day for multiple times per week. Patients often don’t think it’s a problem, even as he discusses their liver-related issues.
“We can’t just keep living and working the way we were 10 years ago,” he said. “We’ve got to change how we approach treatment. We have to treat liver disease and AUD.”
The guideline was supported by several National Institutes of Health grants and an American College of Gastroenterology faculty development grant. The authors declared potential competing interests with various pharmaceutical companies. Dr. Burton reported no financial disclosures.

The Breakthrough Drug Whose Full Promise Remains Unrealized
Celebrating a Decade of Sofosbuvir for Hepatitis C
Prior to 2013, the backbone of hepatitis C virus (HCV) therapy was pegylated interferon (PEG) in combination with ribavirin (RBV). This year-long therapy was associated with significant side effects and abysmal cure rates. Although efficacy improved with the addition of first-generation protease inhibitors, cure rates remained suboptimal and treatment side effects continued to be significant.
Clinicians and patients needed better options and looked to the drug pipeline with hope. However, even among the most optimistic, the idea that HCV therapy could evolve into an all-oral option seemed a relative pipe dream.
The Sofosbuvir Revolution Begins
The Liver Meeting held in 2013 changed everything.
Several presentations featured compelling data with sofosbuvir, a new polymerase inhibitor that, when combined with RBV, offered an all-oral option to patients with genotypes 2 and 3, as well as improved efficacy for patients with genotypes 1, 4, 5, and 6 when it was combined with 12 weeks of PEG/RBV.
However, the glass ceiling of HCV care was truly shattered with the randomized COSMOS trial, a late-breaker abstract that revealed 12-week functional cure rates in patients receiving sofosbuvir in combination with the protease inhibitor simeprevir.
This phase 2a trial in treatment-naive and -experienced genotype 1 patients with and without cirrhosis showed that an all-oral option was not only viable for the most common strain of HCV but was also safe and efficacious, even in difficult-to-treat populations.
On December 6, 2013, the US Food and Drug Administration (FDA) approved sofosbuvir for the treatment of HCV, ushering in a new era of therapy.
Guidelines quickly changed to advocate for both expansive HCV screening and generous treatment. Yet, as this more permissive approach was being recommended, the high price tag and large anticipated volume of those seeking prescriptions were setting off alarms. The drug cost triggered extensive restrictions based on degree of fibrosis, sobriety, and provider type in an effort to prevent immediate healthcare expenditures.
Given its high cost, rules restricting a patient to only one course of sofosbuvir-based therapy also surfaced. Although treatment with first-generation protease inhibitors carried a hefty price of $161,813.49 per sustained virologic response (SVR), compared with $66,000-$100,000 for 12 weeks of all-oral therapy, its uptake was low and limited by side effects and comorbid conditions. All-oral treatment appeared to have few medical barriers, leading payers to find ways to slow utilization. These restrictions are now gradually being eliminated.
Because of high SVR rates and few contraindications to therapy, most patients who gained access to treatment achieved cure. This included patients who had previously not responded to treatment and prioritized those with more advanced disease.
This quickly led to a significant shift in the population in need of treatment. Prior to 2013, many patients with HCV had advanced disease and did not respond to prior treatment options. After uptake of all-oral therapy, individuals in need were typically treatment naive without advanced disease.
This shift also added new psychosocial dimensions, as many of the newly infected individuals were struggling with active substance abuse. HCV treatment providers needed to change, with increasing recruitment of advanced practice providers, primary care physicians, and addiction medication specialists.
Progress, but Far From Reaching Targets
Fast-forward to 2023.
Ten years after FDA approval, 13.2 million individuals infected with HCV have been treated globally, 82% with sofosbuvir-based regimens and most in lower-middle-income countries. This is absolutely cause for celebration, but not complacency.
In 2016, the World Health Assembly adopted a resolution of elimination of viral hepatitis by 2030. The World Health Organization (WHO) defined elimination of HCV as 90% reduction in new cases of infection, 90% diagnosis of those infected, 80% of eligible individuals treated, and 65% reduction of deaths by 2030.
Despite all the success thus far, the CDA Foundation estimates that the WHO elimination targets will not be achieved until after the year 2050. They also note that in 2020, over 50 million individuals were infected with HCV, of which only 20% were diagnosed and 1% annually treated.
The HCV care cascade, by which the patient journeys from screening to cure, is complicated, and a one-size-fits-all solution is not possible. Reflex testing (an automatic transition to HCV polymerase chain reaction [PCR] testing in the lab for those who are HCV antibody positive) has significantly improved diagnosis. However, communicating these results and linking a patient to curative therapy remain significant obstacles.
Models and real-life experience show that multiple strategies can be successful. They include leveraging the electronic medical record, simplified treatment algorithms, test-and-treat strategies (screening high-risk populations with a point-of-care test that allows treatment initiation at the same visit), and co-localizing HCV screening and treatment with addiction services and relinkage programs (finding those who are already diagnosed and linking them to treatment).
In addition, focusing on populations at high risk for HCV infection — such as people who inject drugs, men who have sex with men, and incarcerated individuals — allows for better resource utilization.
Though daunting, HCV elimination is not impossible. There are several examples of success, including in the countries of Georgia and Iceland. Although, comparatively, the United States remains behind the curve, the White House has asked Congress for $11 billion to fund HCV elimination domestically.
As we await action at the national level, clinicians are reminded that there are several things we can do in caring for patients with HCV:
- A one-time HCV screening is recommended in all individuals aged 18 or older, including pregnant people with each pregnancy.
- HCV antibody testing with reflex to PCR should be used as the screening test.
- Pan-genotypic all-oral therapy is recommended for patients with HCV. Cure rates are greater than 95%, and there are few contraindications to treatment.
- Most people are eligible for simplified treatment algorithms that allow minimal on-treatment monitoring.
Without increased screening and linkage to curative therapy, we will not meet the WHO goals for HCV elimination.

Celebrating a Decade of Sofosbuvir for Hepatitis C
Celebrating a Decade of Sofosbuvir for Hepatitis C
Prior to 2013, the backbone of hepatitis C virus (HCV) therapy was pegylated interferon (PEG) in combination with ribavirin (RBV). This year-long therapy was associated with significant side effects and abysmal cure rates. Although efficacy improved with the addition of first-generation protease inhibitors, cure rates remained suboptimal and treatment side effects continued to be significant.
Clinicians and patients needed better options and looked to the drug pipeline with hope. However, even among the most optimistic, the idea that HCV therapy could evolve into an all-oral option seemed a relative pipe dream.
The Sofosbuvir Revolution Begins
The Liver Meeting held in 2013 changed everything.
Several presentations featured compelling data with sofosbuvir, a new polymerase inhibitor that, when combined with RBV, offered an all-oral option to patients with genotypes 2 and 3, as well as improved efficacy for patients with genotypes 1, 4, 5, and 6 when it was combined with 12 weeks of PEG/RBV.
However, the glass ceiling of HCV care was truly shattered with the randomized COSMOS trial, a late-breaker abstract that revealed 12-week functional cure rates in patients receiving sofosbuvir in combination with the protease inhibitor simeprevir.
This phase 2a trial in treatment-naive and -experienced genotype 1 patients with and without cirrhosis showed that an all-oral option was not only viable for the most common strain of HCV but was also safe and efficacious, even in difficult-to-treat populations.
On December 6, 2013, the US Food and Drug Administration (FDA) approved sofosbuvir for the treatment of HCV, ushering in a new era of therapy.
Guidelines quickly changed to advocate for both expansive HCV screening and generous treatment. Yet, as this more permissive approach was being recommended, the high price tag and large anticipated volume of those seeking prescriptions were setting off alarms. The drug cost triggered extensive restrictions based on degree of fibrosis, sobriety, and provider type in an effort to prevent immediate healthcare expenditures.
Given its high cost, rules restricting a patient to only one course of sofosbuvir-based therapy also surfaced. Although treatment with first-generation protease inhibitors carried a hefty price of $161,813.49 per sustained virologic response (SVR), compared with $66,000-$100,000 for 12 weeks of all-oral therapy, its uptake was low and limited by side effects and comorbid conditions. All-oral treatment appeared to have few medical barriers, leading payers to find ways to slow utilization. These restrictions are now gradually being eliminated.
Because of high SVR rates and few contraindications to therapy, most patients who gained access to treatment achieved cure. This included patients who had previously not responded to treatment and prioritized those with more advanced disease.
This quickly led to a significant shift in the population in need of treatment. Prior to 2013, many patients with HCV had advanced disease and did not respond to prior treatment options. After uptake of all-oral therapy, individuals in need were typically treatment naive without advanced disease.
This shift also added new psychosocial dimensions, as many of the newly infected individuals were struggling with active substance abuse. HCV treatment providers needed to change, with increasing recruitment of advanced practice providers, primary care physicians, and addiction medication specialists.
