2025 in Hepatology: New MASLD Therapies, HBV Updates, and More

2025 has marked a clear turning point in hepatology, bringing advances that are reshaping both the scientific landscape and everyday clinical practice. After years defined by limited therapeutic options and slow-moving pipelines, this year delivered transformative progress, from the long-awaited arrival of effective pharmacologic treatments for MASLD/MASH to renewed innovation in viral hepatitis, cholestatic liver diseases, portal hypertension, and alcohol-associated liver disease.

However, the momentum extends well beyond new drugs. Emerging noninvasive diagnostics, evolving disease definitions, AI-enabled pathology, and increasingly patient-centered care models are redefining how clinicians detect, stage, and manage chronic liver disease. Together, these shifts signal a rapidly accelerating era in hepatology that is expanding treatment opportunities while reshaping clinical expectations.

To capture the breadth of this evolution, the editorial team of HCPLive Hepatology invited 7 leading experts to weigh in on the most important advances of 2025:

Hersh Shroff, MD, MPA, an assistant professor of medicine and director of the IHEAL Clinic at the University of North Carolina School of Medicine:

I think in the past year, the biggest news has been the increasing use of medications to treat metabolic dysfunction associated-steatotic liver disease, formerly known as fatty liver disease. The weight loss medications, the GLP-1 receptor agonists, are really changing the game for this disease process. Resmetirom is another new medication we have, and just given the sheer number of patients that we have with this disease process, now finally having medications to treat them, albeit with insurance barriers, which we're working on, but I think it's really promising to be able to at least have options for these patients. Hopefully the government and local partners can help bring the prices of these medications down and increase access, because they really are beneficial.

Zobair Younossi, MD, MPH, chairman of the Global NASH/MASH Council and professor and chairman of Beatty Liver and Obesity Research at Inova Health System:

I think the biggest news in hepatology is the drugs that we are developing for MASH. Resmetirom, semaglutide, and probably the new drugs with FGF21s, so hopefully we'll see the results next year. There is also a lot of interest in other liver diseases, understanding the dynamic nature of what we call steatotic liver disease between MASLD, MetALD, and ALD, that this is a dynamic disease that goes back and forth. So that's an important concept to understand, and there is also some hope in terms of better treatment for viral hepatitis, especially delta hepatitis, which may not be a major issue in the United States but is a major issue in some other parts of the world. So all of these actually gave me more hope that we are going to see more and more innovation and interest in this area.

Wei Zhang, MD, PhD, a transplant hepatologist and assistant professor of medicine at Massachusetts General Hospital and Harvard Medical School:

There have been a few pieces of breaking news in the past year. First, I'd say the most important is steatotic liver disease, and now we finally have 2 approved medications to treat patients with MASH. We used to have no other, or very little, options, except for exercise and lifestyle modification, which is very important, but also hard to do. But now we have medications that actually have been proven to be effective in reducing steatosis and also fibrosis in those patients, so it can prevent further development of advanced liver disease.

Obviously, in addition to that, we're also trying to use a combination of pharmacotherapy and behavioral therapy so once patients lose weight, they'll continue to stay in that weight for a long period of time, and that disease can be controlled or even resolved. In addition to that, what I have noticed is that alcohol-related liver disease continues to be paid attention to. In our liver disease society, we have more researchers, we have more findings in this field, and more and more people are realizing that pharmacotherapy is something that could be utilized by us to manage patients with alcohol-related liver disease, and integrated clinics actually are more utilized across the academic medical centers to manage those patients.

The third part that I've noticed is there are more lectures and more attention that is paid to address psychosocial and structural determinants in patients with chronic liver disease, for example, stigma. This year, we have a specific session for stigma and also psychosocial structural barriers. I think we're paying more and more attention in this area, which is very important, because how patients feel about their disease is also extremely important as to how we can manage and help their disease itself.

Andreas Kremer, MD, PhD, the head of hepatology at University Hospital Zurich:

I don’t want to break it down to one piece of biggest news. I think we have seen a lot of changes from treating underlying diseases, such as in rare cholestatic liver disease the switch to symptom burden, which is more and more addressed in many disorders, which I think is very important to our patients. They sometimes care more about improved symptoms rather than an improved laboratory parameter.

We also see great developments in the field of MASLD and also fibrotic or cirrhotic MASLD. The problem is so far, we have always relied on histology, and we see clear trends towards artificial intelligence based pathology investigations or noninvasive tests to overcome the need for biopsy on a study drug, where we, hopefully, in the future, have certain definitions that indicate this is associated with improved histology, so that we can avoid biopsy and purely rely on noninvasive parameters, whether this is an Agile 4 combined laboratory parameter or a certain elastography-based measurement needs to be shown in the end. There's a clear trend in this large disease moving away.

I think these are important messages and various other aspects a little bit, depending on whom you ask, but I think quite intriguing news we have learned here in Washington, DC.

Naim Alkhouri, MD, chief academic officer of Summit Clinical Research and director of the Steatotic Liver Program at North Shore Gastroenterology:

I think being in the field of hepatology has been very exciting in the last few years. We have new treatments that are being developed for hepatitis B to achieve functional cure, and I think this will be a great addition for these patients. We also see new therapeutics being developed to treat portal hypertension, and these patients have very advanced liver disease. They're on the cusp of decompensation, so if we can take them back into a more stable stage of their disease, that will be a very important development. We are also seeing many new therapeutics to treat cholestatic liver disease, both PSC and PBC, and we also see treatments for genetic cholestasis diseases like progressive familial intrahepatic cholestasis. There's many, many new biomarkers that are being developed and screening algorithms to increase awareness of chronic liver disease in general, so I couldn't be happier to be a hepatologist.

Chari Cohen, DrPH, MPH, a professor at the Baruch S. Blumberg Institute and president of the Hepatitis B Foundation:

We have 2 new treatment guidelines for hepatitis B. EASL came out with their hepatitis B guidelines earlier in the year, and AASLD just came out with their updated hepatitis B guidelines a few days ago. We're excited to see how those are going to be implemented. We are excited as a community to have expanded treatment guidelines, and one of the central tenets of both of those guidelines is shared decision-making. We're very, very pleased to see that medical societies are paying attention to what the patient wants and understanding that the decision to initiate treatment should be a shared one between a clinician and a patient.

Mazen Noureddin, MD, MHSc, a professor of medicine at Houston Methodist Hospital and co-chairman of Summit Clinical Research’s Board of Directors (not included in video):

I think there are a million biggest pieces of news this year. We can talk about that for an hour, but I think the MASH field just got another big boost. There were multiple acquisitions this year, the efruxiferm acquisition, the pegozafermin acquisition, and the efimosfermin acquisition. In addition, pemvidutide came with a primary endpoint, so now we have multiple attractive phase 3 trials. With having big sponsors, I think we'll start seeing combination therapy and more trials going on. This is probably the hottest year for the MASH field ever, and I look forward to many good years coming down.
