In a rapidly expanding therapeutic landscape, the American Gastroenterological Association (AGA) has issued updated practice guidelines for the pharmacological management of moderate to severe ulcerative colitis (UC) in adult outpatients.

“These are the first living guidelines published by a GI society, highlighting the interest and need to provide timely guidance to all stakeholders in a rapidly evolving field,” first author Siddharth Singh, MD, of the Division of Gastroenterology in the Department of Medicine at University of California, San Diego, said in an interview. Living guidance allows for ongoing revision of individual recommendations as new data emerge. Nearly 2 million Americans have UC.

 

Issued in Gastroenterology and updating the last guidance in 2020, the recommendations suggest more efficacious drugs should be used sooner. “Early use of advanced therapies including biologics and small-molecule drugs are more effective than 5-aminosalicylates [5-ASAs] or thiopurines and methotrexate for most patients with moderate to severe UC and those with poor prognostic factors,” coauthor and gastroenterologist Manasi Agrawal, MD, MS, an assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York City, said in an interview.

“We provide a practical guidance based on best-available evidence to make it easy for the treating clinician to make informed choices from the multiplicity of available treatments for UC,” added guidelines coauthor Ashwin Ananthakrishnan, MBBS, MPH, AGAF, a gastroenterologist at Massachusetts General Hospital in Boston.

 

The comprehensive, patient-centered document comes with this caveat from the AGA panel: “These guidelines are meant to be broad recommendations for management of patients with moderate to severe UC and are not intended to address the intricacies of individual patients,” they wrote. “Provider experience and patient values and preferences can inform treating providers and patients to reasonably choose alternative treatment options.”

One gastroenterologist who has been eagerly awaiting these guidelines but not involved in the panel is James D. Lewis, MD, MSCE, AGAF, a professor of medicine and epidemiology at Perelman School of Medicine at the University of Pennsylvania, Philadelphia. “The choice of medications for moderately to severely active UC has expanded tremendously in the past few years,” he said in an interview. “This resulted in the dismantling of the historical therapeutic pyramid.” And while there are many more treatment options, knowing which medication to use for which patient and in which sequence has become much more complicated. 

“These guidelines will be extremely helpful for clinicians trying to navigate this new era of UC care,” he said.

The guidelines also outline implementation considerations for optimal use in different scenarios. “Key considerations include patient-related factors such as age, frailty, other health conditions, consideration for pregnancy, patient preferences, and access to healthcare,” Agrawal said.

 

Specifics

Overall, the guidance recommends advanced or immunomodulatory therapy after failure of 5-ASAs rather than a step-up approach. Moderate to severe disease is defined as a Mayo endoscopic severity subscore of 2 or 3.

The recommendation may also apply to mild disease in the presence of a high burden of inflammation and a poor prognosis or steroid dependence or resistance.

The AGA guideline panelists took account of differences in treatment efficacy between drugs within the same therapeutic class and made their recommendations by specific drugs rather than therapy class.

Based on varying degrees of evidence certainty, the AGA recommends or suggests the following management specifics in adult outpatients with moderate to severe disease:

• Any of the following is recommended over no treatment: infliximab (Remicade), golimumab (Simponi), vedolizumab (Entyvio), tofacitinib (Xeljanz), upadacitinib (Rinvoq), ustekinumab (Stelara), ozanimod (Zeposia), etrasimod (Velsipity), risankizumab (Skyrizi), and guselkumab (Tremfya).
• Adalimumab (Humira), filgotinib (Jyseleca), and mirikizumab (Omvoh) are suggested over no treatment.
• Biosimilars to infliximab, adalimumab, and ustekinumab can be considered of equivalent efficacy to their originator drugs.
• For patients naive to advanced therapies, the AGA panel proposes using a higher-efficacy medication (eg, infliximab, vedolizumab, ozanimod, etrasimod, upadacitinib, risankizumab, and guselkumab) or an intermediate-efficacy medication (golimumab, ustekinumab, tofacitinib, filgotinib, and mirikizumab) rather than a lower-efficacy medication such as adalimumab.
• In patients previously exposed to advanced therapy, particularly tumor necrosis factor (TNF)–alpha antagonists, the panel suggests using a higher-efficacy medication (tofacitinib, upadacitinib, and ustekinumab) or an intermediate-efficacy agent (filgotinib, mirikizumab, risankizumab, and guselkumab) over a lower-efficacy medication (adalimumab, vedolizumab, ozanimod, and etrasimod).
• The panel suggests against the use of thiopurine monotherapy for inducing remission but suggests thiopurine monotherapy over no treatment for maintenance of (typically corticosteroid-induced) remission.
• The panel suggests against the use of methotrexate monotherapy for induction or maintenance of remission.
• Infliximab, adalimumab, and golimumab in combination with an immunomodulator are suggested over monotherapy.
• The panel makes no recommendation for or against non-TNF antagonist biologics in combination with an immunomodulator over non-TNF biologics alone.
• For patients in corticosteroid-free clinical remission for at least 6 months on combination therapy with TNF antagonists and immunomodulators, the panel suggests against withdrawing TNF antagonists but makes no recommendation for or against withdrawing immunomodulators.
• For those who have failed 5-ASAs and have escalated to immunomodulators or advanced therapies, the panel suggests stopping these agents. It suggests the early use of advanced therapies and/or immunomodulator therapy rather than gradual step-up after failure of 5-ASAs.

According to Lewis, the guidance will be useful to both community physicians and highly specialized gastroenterologists. “While few practicing physicians will be able to commit the entirety of the classifications in this guideline to memory, the tool is a quick reference resource to help providers and patients to choose between the many options,” he said.

However, he noted that not all patients and providers may have the same priorities as the guidelines. “There are a few nuances to the methods of the AGA guidelines. For example, the panel prioritized efficacy over safety because the incidence of serious adverse events secondary to medications is relatively rare.”

Lewis also noted that the way the panel classified higher-, intermediate-, and lower-efficacy medications sometimes produced surprising results. “For example, among patients naive to advanced therapies, the IL [interleukin]–23 inhibitors risankizumab and guselkumab were classified as higher efficacy, while the IL-12/23 inhibitor ustekinumab was considered intermediate efficacy,” he said. “These were reversed for patients with prior exposure to advanced therapies, where ustekinumab was considered higher efficacy and all three IL-23 inhibitors were considered intermediate efficacy.”

 

The Future

The panel identified several knowledge gaps that future studies should address. These include a paucity of head-to-head comparison trials, including active comparators to accurately inform positioning of different treatments and therapeutic mechanisms.

The panelists also noted a literature gap on the efficacy of different therapies in the setting of failure or intolerance to non-TNF antagonist advanced therapy, which could be relevant to drugs that may have a greater overlap in their therapeutic mechanisms — for instance, anti-trafficking agents.

They pointed to a paucity of data on how predictive models can inform future treatment selection in the real-world setting. “There is clearly a need for identifying biomarkers predictive of response to individual therapies, to facilitate optimal choice of therapies,” they wrote.

The panel also recognized that novel therapeutic strategies may soon be in use, including combination advanced therapy or episodic use of nonimmunogenic advanced therapies such as small molecules. “Further primary data are required to accurately inform the positioning of such strategies,” they wrote.

These guidelines were fully funded by the AGA Institute. Singh and Agrawal are supported by the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK), and Ananthakrishnan is supported by the NIDDK, as well as by the Leona M. and Harry B. Helmsley Charitable Trust and the Chleck Family Foundation. Singh disclosed Institutional research grants from Pfizer. Agrawal reported consulting for Douglas Pharmaceuticals. Several coauthors disclosed receiving consulting fees and/or research support from various private companies in the healthcare field. One author reported stock ownership stock in Exact Sciences. Lewis reported consulting, advisory board service, or data monitoring for Amgen, Arena Pharmaceuticals, Bristol Myers Squibb, Celgene, Eli Lilly and Company, Galapagos, Gilead, Janssen Pharmaceuticals, Merck, Pfizer, Protagonist Therapeutics, and Sanofi. He received research funding or in-kind support from Nestle Health Science, Takeda, Janssen Pharmaceuticals, AbbVie, and Eli Lilly and has had educational grants from Janssen.

SAN DIEGO — An artificial intelligence (AI)–driven algorithm may be able to accurately detect early-stage metabolic dysfunction–associated steatotic liver disease (MASLD) based on imaging findings and other criteria in patient electronic medical records, according to new research.

Among the patients identified by the algorithm as meeting the criteria for MASLD, only a small percentage had an MASLD-associated diagnostic code.

“A significant portion of patients who meet criteria for MASLD go undiagnosed, which can lead to delays in care and progression to advanced liver disease,” said lead author Ariana Stuart, MD, an internal medicine resident at the University of Washington, Seattle, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).

“However, people shouldn’t interpret our findings as a lack of primary care training or management,” she said. “Instead, this study indicates that AI can complement physician workflow and address the limitations of traditional clinical practice.”

 

Developing an MASLD Algorithm

Typically, the identification of MASLD has relied on clinician recognition and descriptions in chart notes, Stuart said. Early-stage disease often goes unnoticed, particularly if patients remain asymptomatic, until cirrhosis develops.

To address this, Stuart and colleagues created a machine learning, natural language processing AI algorithm on the basis of MASLD criteria from AASLD: Hepatic steatosis on imaging and at least one metabolic factor (elevated body mass index, hypertension, prediabetes or diabetes, or dyslipidemia). The model was validated by two physicians, who manually reviewed monthly cohorts generated by the algorithm.

Between December 2023 and May 2024, the researchers used the algorithm to analyze an MASLD cohort from medical centers in the Seattle area. The mean age was 51 years, 44% were women, and 68% were White. Those with alcohol-associated liver disease, metastatic malignancy, and autoimmune, genetic, and infectious causes of liver disease were excluded.

The algorithm identified 957 patients with imaging that matched MASLD criteria.

Among those, 137 patients (17%) identified by the algorithm had an MASLD-associated diagnostic code. For these patients, the mean time from initial imaging with steatosis to diagnosis was 33 days, according to patient records.

An additional 26 patients received an MASLD diagnosis during the study period, with a mean time to diagnosis of 56.2 days.

In terms of patient management, 245 patients (26%) had contact with a gastroenterologist or hepatologist based on documentation of a letter, phone call, or office visit. In addition, 546 patients (57%) were screened for hepatitis C.

After adjusting for an over-inclusion error rate of 12.8% and an overdiagnosis rate of 0.02%, the research team found 697 patients (83%) lacked a relevant diagnosis. After multiple iterations, the algorithm achieved an accuracy of about 88%, Stuart said.

 

Considering Future AI Use

Stuart and colleagues are now testing the algorithm in larger groups and across longer periods.

After that, they intend to implement a quality improvement program to increase awareness for clinicians and primary care providers, as well as train users on how to interpret and move forward with findings of hepatic steatosis in patient records.

For instance, future AI models could flag patients for additional testing, improve chart review, and aid in research efforts around cardiometabolic comorbidities associated with MASLD, she said.

Looking ahead, AI tools such as these represent what’s possible for advancements in research, patient care, and clinical workflows, said Ashley Spann, MD, assistant professor and transplant hepatologist at Vanderbilt University, Nashville, Tennessee, and director of clinical research informatics for Vanderbilt’s Gastroenterology Division.

“AI, in my view, is actually augmented intelligence,” she added. “We need to think about the people and processes involved.”

Spann, who spoke about the use of AI tools in medicine in general, stressed the need for transparency in AI use, careful validation of input-output data, frameworks for machine learning models in medicine, and standardization across institutions.

“What we ultimately need is an infrastructure that supports the simultaneous deployment and evaluation of these models,” she said. “We all need to be on the same page and make sure our models work in multiple settings and make adjustments based on algorithmovigilance afterward.”

Stuart reported no relevant disclosures. Spann serves on Epic’s hepatology steering board, which has focused on how to use AI tools in electronic medical records.

SAN DIEGO — An artificial intelligence (AI)–driven algorithm may be able to accurately detect early-stage metabolic dysfunction–associated steatotic liver disease (MASLD) based on imaging findings and other criteria in patient electronic medical records, according to new research.

Among the patients identified by the algorithm as meeting the criteria for MASLD, only a small percentage had an MASLD-associated diagnostic code.

“A significant portion of patients who meet criteria for MASLD go undiagnosed, which can lead to delays in care and progression to advanced liver disease,” said lead author Ariana Stuart, MD, an internal medicine resident at the University of Washington, Seattle, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).

“However, people shouldn’t interpret our findings as a lack of primary care training or management,” she said. “Instead, this study indicates that AI can complement physician workflow and address the limitations of traditional clinical practice.”

 

Developing an MASLD Algorithm

Typically, the identification of MASLD has relied on clinician recognition and descriptions in chart notes, Stuart said. Early-stage disease often goes unnoticed, particularly if patients remain asymptomatic, until cirrhosis develops.

To address this, Stuart and colleagues created a machine learning, natural language processing AI algorithm on the basis of MASLD criteria from AASLD: Hepatic steatosis on imaging and at least one metabolic factor (elevated body mass index, hypertension, prediabetes or diabetes, or dyslipidemia). The model was validated by two physicians, who manually reviewed monthly cohorts generated by the algorithm.

Between December 2023 and May 2024, the researchers used the algorithm to analyze an MASLD cohort from medical centers in the Seattle area. The mean age was 51 years, 44% were women, and 68% were White. Those with alcohol-associated liver disease, metastatic malignancy, and autoimmune, genetic, and infectious causes of liver disease were excluded.

The algorithm identified 957 patients with imaging that matched MASLD criteria.

Among those, 137 patients (17%) identified by the algorithm had an MASLD-associated diagnostic code. For these patients, the mean time from initial imaging with steatosis to diagnosis was 33 days, according to patient records.

An additional 26 patients received an MASLD diagnosis during the study period, with a mean time to diagnosis of 56.2 days.

In terms of patient management, 245 patients (26%) had contact with a gastroenterologist or hepatologist based on documentation of a letter, phone call, or office visit. In addition, 546 patients (57%) were screened for hepatitis C.

After adjusting for an over-inclusion error rate of 12.8% and an overdiagnosis rate of 0.02%, the research team found 697 patients (83%) lacked a relevant diagnosis. After multiple iterations, the algorithm achieved an accuracy of about 88%, Stuart said.

 

Considering Future AI Use

Stuart and colleagues are now testing the algorithm in larger groups and across longer periods.

After that, they intend to implement a quality improvement program to increase awareness for clinicians and primary care providers, as well as train users on how to interpret and move forward with findings of hepatic steatosis in patient records.

For instance, future AI models could flag patients for additional testing, improve chart review, and aid in research efforts around cardiometabolic comorbidities associated with MASLD, she said.

Looking ahead, AI tools such as these represent what’s possible for advancements in research, patient care, and clinical workflows, said Ashley Spann, MD, assistant professor and transplant hepatologist at Vanderbilt University, Nashville, Tennessee, and director of clinical research informatics for Vanderbilt’s Gastroenterology Division.

“AI, in my view, is actually augmented intelligence,” she added. “We need to think about the people and processes involved.”

Spann, who spoke about the use of AI tools in medicine in general, stressed the need for transparency in AI use, careful validation of input-output data, frameworks for machine learning models in medicine, and standardization across institutions.

“What we ultimately need is an infrastructure that supports the simultaneous deployment and evaluation of these models,” she said. “We all need to be on the same page and make sure our models work in multiple settings and make adjustments based on algorithmovigilance afterward.”

SAN DIEGO — Semaglutide, a glucagon-like peptide 1 (GLP-1) receptor agonist, appears to safely and effectively treat metabolic dysfunction–associated steatohepatitis (MASH) among patients with moderate to advanced liver fibrosis, according to interim results from a phase 3 trial.

At 72 weeks, a 2.4-mg once-weekly subcutaneous dose of semaglutide demonstrated superiority, compared with placebo, for the two primary endpoints: Resolution of steatohepatitis with no worsening of fibrosis and improvement in liver fibrosis with no worsening of steatohepatitis.

“It’s been a long journey. I’ve been working with GLP-1s for 16 years, and it’s great to be able to report the first GLP-1 receptor agonist to demonstrate efficacy in a phase 3 trial for MASH,” said lead author Philip Newsome, MD, PhD, director of the Roger Williams Institute of Liver Studies at King’s College London in England.

“There were also improvements in a slew of other noninvasive markers,” said Newsome, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).

Although already seen in a broader context, “it’s nice to see a demonstration of the cardiometabolic benefits in the context of MASH and a reassuring safety profile,” he added.

 

Interim ESSENCE Trial Analysis

ESSENCE (NCT04822181) is an ongoing multicenter, phase 3 randomized, double-blind, placebo-controlled outcome trial studying semaglutide for the potential treatment of MASH.

The trial includes 1200 participants with biopsy-defined MASH and fibrosis, stages F2 and F3, who were randomized 2:1 to a once-weekly subcutaneous injection of 2.4 mg of semaglutide or placebo for 240 weeks. After initiation, the semaglutide dosage was increased every 4 weeks up to 16 weeks when the full dose (2.4 mg) was reached.

In a planned interim analysis, the trial investigators evaluated the primary endpoints at week 72 for the first 800 participants, with biopsies taken at weeks 1 and 72.

A total of 534 people were randomized to the semaglutide group, including 169 with F2 fibrosis and 365 with F3 fibrosis. Among the 266 participants randomized to placebo, 81 had F2 fibrosis and 185 had F3 fibrosis.

At baseline, the patient characteristics were similar between the groups (mean age, 56 years; body mass index, 34.6). A majority of participants also were White (67.5%), women (57.1%), had type 2 diabetes (55.9%), F3 fibrosis (68.8%), and enhanced liver fibrosis (ELF) scores around 10 (55.5%).

For the first primary endpoint, 62.9% of those in the semaglutide group and 34.1% of those in the placebo group reached resolution of steatohepatitis with no worsening of fibrosis. This represented an estimated difference in responder proportions (EDP) of 28.9%.

In addition, 37% of those in the semaglutide group and 22.5% of those in the placebo group met the second primary endpoint of improvement in liver fibrosis with no worsening of steatohepatitis (EDP, 14.4%).

Among the secondary endpoints, combined resolution of steatohepatitis with a one-stage improvement in liver fibrosis occurred in 32.8% of the semaglutide group and 16.2% of the placebo group (EDP, 16.6%).

In additional analyses, Newsome and colleagues found 20%-40% improvements in liver enzymes and noninvasive fibrosis markers, such as ELF and vibration-controlled transient elastography liver stiffness.

Weight loss was also significant, with a 10.5% reduction in the semaglutide group compared with a 2% reduction in the placebo group.

Cardiometabolic risk factors improved as well, with changes in blood pressure measurements, hemoglobin A1c scores, and cholesterol values.

Although not considered statistically significant, patients in the semaglutide group also reported greater reductions in body pain.

In a safety analysis of 1195 participants at 96 weeks, adverse events, severe adverse events, and discontinuations were similar in both groups. Not surprisingly, gastrointestinal side effects were more commonly reported in the semaglutide group, Newsome said.

 

Highly Anticipated Results

After Newsome’s presentation, attendees applauded.

Rohit Loomba, MD, a gastroenterologist at the University of California, San Diego, who was not involved with the study, called the results the “highlight of the meeting.”

This sentiment was echoed by Naga Chalasani, MD, AGAF, a gastroenterologist at Indiana University Medical Center, Indianapolis, who called the results a “watershed moment in the MASH field” with “terrific data.”

 

Based on questions after the presentation, Newsome indicated that future ESSENCE reports would look at certain aspects of the results, such as the 10% weight loss among those in the semaglutide group, as well as the mechanisms of histological and fibrosis improvement.

“We know from other GLP-1 trials that more weight loss occurs in those who don’t have type 2 diabetes, and we’re still running those analyses,” he said. “Weight loss is clearly a major contributor to MASH improvement, but there seem to be some weight-independent effects here, which are likely linked to insulin sensitivity or inflammation. We look forward to presenting those analyses in due course.”

 

In a comment, Kimberly Ann Brown, MD, AGAF, chief of gastroenterology and hepatology at Henry Ford Health System in Detroit, Michigan, AASLD Foundation chair, and comoderator of the late-breaking abstract session, spoke about the highly anticipated presentation.

“This study was really the pinnacle of this meeting. We’ve all been waiting for this data, in large part because many of our patients are already using these medications,” Brown said. “Seeing the benefit for the liver, as well as lipids and other cardiovascular measures, is so important. Having this confirmatory study will hopefully lead to the availability of the medication for this indication among our patients.”

Newsome reported numerous disclosures, including consultant relationships with pharmaceutical companies, such as Novo Nordisk, Boehringer Ingelheim, and Madrigal Pharmaceuticals. Loomba has research grant relationships with numerous companies, including Hanmi, Gilead, Galmed Pharmaceuticals, Galectin Therapeutics, Eli Lilly, Bristol-Myers Squibb, and Boehringer Ingelheim. Chalasani has consultant relationships with Ipsen, Pfizer, Merck, Altimmune, GSK, Madrigal Pharmaceuticals, and Zydus. Brown reported no relevant disclosures.
