Surfing the MASH Tsunami

• S6 - E6 - Remembering Stephen Harrison and His Many Contributions to MASH

  00:00:00 Surf's Up, Season 6, Episode 6.On April 23, 2024, our colleague and co-founder, Stephen Harrison, passed away suddenly. This week, Surfing the MASH Tsunami remembers Stephen with two of his closest associates and continues our annual MASH Drug Development roundtable held in his honor. 00:00:04:24 - A Deep Dive into Drug Development, Part 2The second portion of the Drug Development roundtable primarily focuses on three key issues. The first, uptake of resmetirom, starts with Naim Alkhouri discussing his experience in the Arizona Liver Health Clinics with over 650 patients in the year since resmetirom was approved and shifts to the various European panelists (Jörn Schattenberg, Louise Campbell and Sven Francque) estimating when it might be approved in their countries and how widely it might be reimbursed.  The second topic, incretin agonists, focuses on exciting prospects for other incretin agonists in development, as well as some semaglutide combination therapies. The third, NIT clinical trials, covers prospects that non-biopsy clinical trials might be approved sometime in the near future.00:16:20 - Remembering Stephen Harrison I: An Interview with Summit Clinical Research CEO Gail HinksonSummit CEO Gail Hinkson joins Roger Green for the first time on SurfingMASH to discuss her business partner. Gail discusses how the two originally formed Pinnacle Clinical Research and how Pinnacle led to Summit. She proceeds to discuss the current size and reach of both Pinnacle and Summit. Focusing on Summit, Gail describes the company as an Integrated Research Organization (IRO), highlighting its distinct role within the MASH firmament. In the final section of the interview, Gail discusses how Stephen's personality, goals, and vision continue to live on at Summit today.00:34:31 - Remembering Stephen Harrison II: An Interview with Naim Alkhouri Announcing That He Is Joining SummitNewly announced Summit Chief Academic Officer Naim Alkhouri joins this episode for a second time, but in a very different role. Naim discusses his personal history with Stephen and what he loved and respected about his "dear friend." He then makes a major announcement: he is joining Summit as Chief Academic Officer. He shares the many elements of this role, particularly his excitement that Summit can become the entity that educates a wide range of healthcare and commercial professionals on what MASH is and how it is treated. The scope of this vision, combined with what Gail discussed, portrays a level of energy, ambition and vision worthy of Stephen Harrison.00:55:55 - ConclusionAs part of this memorial week, Roger Green forgoes the usual business report, which will return next week.

• S6 - E5.2 - Newsmaker: Naga Chalasani on Real-World Experience Prescribing Resmetirom

  This weekend’s Newsmaker, Indiana University hepatologist and key opinion leader Naga Chalasani, joins Roger Green to discuss Early Experience with Resmetirom To Treat Metabolic-Associated Steatohepatitis with Fibrosis in a Real-World Setting, an article his group published recently in Hepatology Communications. He shares highlights from the paper and points out the one key area in which his group found room for improvement in their initial protocol. Naga and colleagues wrote this paper after learning from Madrigal Pharmaceuticals that they were among the largest early prescribers of resmetirom and, relative to others, had achieved reimbursement with virtually all their patients and a high percentage of patients actually starting the medication. After receiving requests from other states for advice, the group decided to author this paper.In the paper, Naga and colleagues focused on patient selection, care pathway, how IUHealth got the medicine to their patients, and experience with safety and tolerability.In the paper, Naga and colleagues discuss their experiences in prescribing resmetirom for 113 patients in the first seven months after resmetirom's approval. Of these, IUHealth succeeded in achieving reimbursement for 110 of them. Of these patients, 83 initiated therapy, and 16% of those discontinued. In this interview, Naga shares some of the decisions that made the group so successful in the first three areas and identifies one subsequent area where the group found an opportunity for improvement: systematic follow-up with patients after prescribing. He attributes the 16% discontinuation rate to a "prescribe and forget" policy, similar to one that was successful in HCV, where clinicians prescribed without systematic follow-up until blood levels were obtained three months later. With a "prescribe and follow up" policy that includes phone calls at 1 and 3 months, he anticipates discontinuation rates will fall to something akin to the 5% rate in Phase 3 trials. What makes this interview so fascinating is Naga's description of the thinking that went behind specific decisions the group made in terms of patient management and pathway and suggests other options that might work as well. In all, this interview provides an excellent guide for clinics and providers on how to best integrate resmetirom into their practices.

• S6 - E5.3 - Expert: Scott Friedman on Gene Therapy and Advances in Liver Science

  This week’s expert, Hepatologist and Key Opinion Leader Scott Friedman, joins Roger to discuss advances in acceptance of gene therapy and knowledge in other areas of basic liver science. When discussing science, he pays particular attention to findings on the diversity of stellate cells and his interest in CAR-T as a therapy for liver disease.This conversation starts with Scott discussing gene therapy. Specifically, he applauds the idea that gene therapy is  becoming accepted in many diseases after a faulty start years ago, due to an unfortunate patient death in a badly controlled trial.  He comments that this acceptance has unique benefits in liver disease because the liver can regenerate so much faster and more efficiently than other organs. He mentions some of the rare liver diseases in which patients are benefiting from gene therapy, and notes that we now have gene therapies and early-stage trials to target PNPLA3 and  other genes associated with MASH and MASH cirrhosis. Next, Scott discusses stellate cells, which he has discussed in earlier episodes of SurfingMASH. Science is increasingly demonstrating how many different types of heterogeneous stellate cells exist. As Scott puts it, these cells "come in many flavors," each of which plays a different role in cell generation or cell death. In fact, the specific therapeutic challenges that present themselves may vary as a patient moves along the pathway from F1 to F2 to F3 to F4. Further, we are learning that there may be several different forms of MASH to present differently at a cellular level. This makes tremendous sense, given that no one drug has proven successful in even a significant majority of patients yet. As the conversation winds down, Scott shares what he describes as a "sobering note" about the state of research funding in America in 2025. As he notes, there are certain kinds of applied and developmental research that private companies do well, but other kinds of basic research that only occur when funded in public and not-for-profit sectors. As a specific example, he cites CRISPR, initially funded publicly and now in the hands of biotech companies, which is used to treat a variety of diseases more effectively than they could have been treated before, if at all. He also comments that a poor early commercial decision slowed the development of statins.

• S6 - E5.1 - FGF-21s and A Promising Future on Cirrhosis

  This conversation is the opening segment of SurfingMASH's April discussion, in memory of Stephen A. Harrison, on drug development. In addition to co-hosts Jörn Schattenberg, Louise Campbell and Roger Green, panelists include hepatologists and key opinion leaders Sven Francque and Naim Alkhouri. This opening discussion focuses on exciting advances in one drug class (FGF-21s) and, more broadly, on exploring ways to treat cirrhosis. As Naim points out in his opening comment, these two issues— cirrhosis as a challenge and FGF-21s as a possible solution path —intersect in clear and exciting ways. He notes that the FGF-21 efruxifermin has been reported to have significant improvement in patients with cirrhosis, while the FGF-21 pegozafermin has shared positive results in a small cohort of patients. He also notes that a third FGF-21, efimosfermin alfa, has results in advanced non-cirrhotic MASH that suggest potential for similar efficacy in patients with cirrhosis, but this must be studied and confirmed in clinical trials. He mentions that resmetirom may also be showing signs of efficacy in some patients with cirrhosis. The entire package, he says, is a "game changer."Jörn notes that we are having parallel advances in treatment for advanced, non-cirrhotic patients. Sven concurs and comments that we are seeing effects that are not strictly related to metabolic disease. There is exceptional power that we can demonstrate one-level regression in sicker patients. The three agree that, at the same time, we are seeing cirrhosis trials that will lead to outcomes data; outcomes trials in non-cirrhotic medications may not be far away.Roger asks whether we are making progress in treating patients living with decompensated cirrhosis. Sven discusses what we are learning about treating portal hypertension, which is an important benefit unrelated to fibrosis regression. Simply improving portal hypertension will have an impact on endpoints. Naim points out that some ongoing trials include patients with cirrhosis, including survodutide and belapectin. Louise notes it will require "great P.R." to reverse some of the current perceptions about cirrhosis, but that this is "great." Naim states that even today, we have "a lot to offer" patients with portal hypertension or other symptoms of decompensation. As he concludes, he notes that this is underappreciated today.

• S6 - E5 - Drug Development Week: FGF-21s, Cirrhosis, Resmiterom, Gene Therapies

  00:00:00 - Surf's Up: Season 6 Episode 5Host Roger Green briefly describes this episode’s three sections and introduces Roundtable guests. The Roundtable panel shares groundbreakers. 00:10:39 - Roundtable: A Deep Dive Into Drug Development, Part OneThe opening portion of this month's roundtable centers around two issues: exciting data for FGF-21s and, more generally, treating patients with cirrhosis. Naim Alkhouri sets the tone in his opening comments, which start by focusing on the exciting SYMMETRY data from efruxifermin and then hones in on FGF-21s and resmetirom in cirrhosis. The rest of the conversation features Jörn Schattenberg, Sven Francque and Naim discussing therapies in development for compensated and decompensating cirrhosis.00;24:44 - Newsmaker: Naga Chalasani on Real-World Experience Prescribing ResmetiromNaga joins Roger to discuss the paper Early Experience with resmetirom to treat Metabolic Dysfunction-Associated Steatohepatitis With Fibrosis in a Real-World Setting from his group at Indiana University, which his group authored and Hepatology Communications recently posted. The paper, based on IU Health's experience with its first 113 resmetirom patients, shares the group's practical experience developing processes to work closely with the specialty pharmacies dispensing resmetirom and, finally, concludes that a more engaged patient management strategy might reduce drug discontinuation to a level comparable with clinical trials.  00:47:21 - Expert: Scott Friedman on Gene Therapy, Diversity of Stellate Cell Types, Other Basic Liver ScienceScott and Roger cover a range of basis science topics in a fast-moving 19-minute discussion. It starts with Scott discussing the increasing acceptance that gene therapy is an acceptable way to treat a range of liver diseases, many of which are orphan or ultra-orphan but, in fact, include potential gene therapies for non-cirrhotic MASH and MASH cirrhosis. He notes that in addition to classic gene therapy, which introduces protective gene variants into the systems of patients with the risky variants, gene therapy is now looking to introduce FGF-21 into patients through genetic modification. From there, the conversation covers CAR-T therapy, the increasing ability to identify many different types of stellate cells and the idea that the most effective therapy for eary fibrosis, advanced fibrosis and cirrhosis might require fundamentally different kinds of interventions. The two final elements are the idea that what we now call "MASH" may be several diseases with different etiologies with similar manifestations and a passionate call for all of us to support maintaining NIH funding in whatever ways we can.01:06:45 - Business ReportAs Roger copes with his laryngitis, AI voices deliver an abbreviated business report
