Efficacy and Safety of Fibroblast Growth Factor‐21 Analogs for the Treatment of Metabolic Dysfunction‐Associated Steatohepatitis: A Systematic Review and Meta‐Analysis

Review

Author: Kim, Min‐Soo ; Jeon, Nakyung ; Rhee, Su‐jin ; Han, Nayoung ; Staatz, Christine E. ; Baek, In‐hwan ; Jeong, Changhyeon

Fibroblast growth factor (FGF)‐21 analogs are potential therapeutic candidates for metabolic dysfunction‐associated steatohepatitis (MASH). This systematic review and meta‐analysis aimed to assess the efficacy and safety of the FGF‐21 analogs, efruxifermin, pegbelfermin, and pegozafermin for MASH treatment. A comprehensive systematic review and meta‐analysis of randomized controlled trials from five major databases was conducted. Primary efficacy outcomes focused on liver histological improvement, while secondary efficacy outcomes encompassed reductions in liver fat content and improvements in biochemical parameters. Safety outcomes examined included treatment‐emergent adverse events (TEAEs), treatment‐related TEAEs, TEAEs leading to discontinuation, and serious TEAEs. Eight eligible studies involving 963 patients were included in this review. Compared with the placebo group, the FGF‐21 analog‐treated group exhibited significantly improved primary efficacy outcomes, specifically ≥1 stage improvement in fibrosis with no worsening of MASH (risk ratio [RR] = 1.83; 95% confidence interval [CI] = 1.27–2.62) and at least two‐point improvement in the non‐alcoholic fatty liver disease activity score with no worsening of fibrosis (RR = 2.85; 95% CI = 2.06–3.95). Despite an increased risk of TEAEs (RR = 1.17; 95% CI = 1.08–1.27) and treatment‐related adverse events (RR = 1.75; 95% CI = 1.40–2.19), FGF‐21 analogs exhibited an acceptable safety profile. FGF‐21 analogs were significantly better in achieving liver histological improvements and beneficial biochemical outcomes compared with placebo, with a tolerable safety pattern. These findings shed light on the efficacy and safety of FGF‐21 analogs and provide valuable evidence for their application as MASH therapeutics.

NAFLD and NASH: etiology, targets and emerging therapies

Review

Author: Wei, Shulin ; Xu, Suowen ; Evans, Paul C ; Wang, Li

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) pose a significant threat to human health and cause a tremendous socioeconomic burden. Currently, the molecular mechanisms of NAFLD and NASH remain incompletely understood, and no effective pharmacotherapies have been approved. In the past five years, significant advances have been achieved in our understanding of the pathomechanisms and potential pharmacotherapies of NAFLD and NASH. Research advances include the investigation of the effects of the fibroblast growth factor 21 (FGF21) analog pegozafermin and the thyroid hormone receptor-β (THRβ) agonist resmetriom on hepatic fat content, NASH resolution and/or fibrosis regression. Future directions of NAFLD and NASH research (including combination therapy, organoids and humanized mouse models) are also discussed in this state-of-the-art review.

In March 2024, Madrigal Pharmaceuticals' groundbreaking product, REZDIFFRA (resmetirom), a once-daily, oral THR-ß agonist, received accelerated endorsement from the US FDA based on results from the Phase III MAESTRO-NASH trial. This approval marks a significant stride in the medical landscape, as REZDIFFRA becomes the inaugural and sole FDA-sanctioned therapy for adults afflicted with non-cirrhotic MASH, accompanied by moderate to advanced liver scarring (fibrosis) corresponding to stages F2–F3 fibrosis. Discover which therapies are expected to grab the major MASH market share @ Metabolic Dysfunction-Associated Steatohepatitis Market Report Metabolic Dysfunction-Associated Steatohepatitis Overview Metabolic dysfunction-associated steatohepatitis (MASH) is a progressive liver disease that stems from metabolic dysfunction, often linked to obesity, diabetes, and other conditions of metabolic syndrome. MASH is characterized by the accumulation of fat in liver cells, accompanied by inflammation and liver cell injury, which can progress to fibrosis, cirrhosis, or even liver cancer. The primary drivers of MASH include insulin resistance, obesity, type 2 diabetes, and dyslipidemia. Genetic predisposition and a sedentary lifestyle also play significant roles. Environmental factors, such as a poor diet high in sugars and fats, exacerbate the condition. MASH is often asymptomatic in its early stages. When symptoms occur, they can include fatigue, vague abdominal discomfort, or pain in the upper right quadrant. In advanced stages, signs of liver dysfunction such as jaundice, swelling of the abdomen or legs, and confusion may arise. Diagnosis involves a combination of clinical history, physical examination, and diagnostic tests. Blood tests measuring liver enzymes (ALT, AST) often indicate liver inflammation. Imaging techniques like ultrasound, MRI, or FibroScan can identify liver fat and fibrosis. In some cases, a liver biopsy is required to confirm the diagnosis and assess disease severity. Metabolic Dysfunction-Associated Steatohepatitis Epidemiology Segmentation The MASH epidemiology section provides insights into the historical and current MASH patient pool and forecasted trends for the 7MM. It helps recognize the causes of current and forecasted patient trends by exploring numerous studies and views of key opinion leaders. The MASH market report proffers epidemiological analysis for the study period 2020–2034 in the 7MM segmented into: Prevalent Cases of MASH Diagnosed Prevalent Cases of MASH Gender-specific Diagnosed Prevalent Cases of MASH Severity-specific Diagnosed Prevalent Cases of MASH Metabolic Dysfunction-Associated Steatohepatitis Treatment Market The approval of REZDIFFRA (resmetirom) in March 2024 represents a pivotal achievement in medical innovation, transforming the treatment landscape for MASH disease. This groundbreaking therapy addresses the root causes of MASH, offering renewed hope to patients grappling with this challenging condition. Clinical trials have shown impressive results, with REZDIFFRA effectively reducing symptoms like inflammation and fibrosis, enhancing liver function, and improving patients' quality of life. By providing healthcare professionals with a robust treatment option, this approval addresses a critical unmet need and has the potential to significantly alleviate the complications linked to advanced liver disease. The prevalence of MASLD is strongly linked to type 2 diabetes mellitus and obesity, particularly in individuals with a higher body mass index. However, MASLD occurrence is reduced in T2DM patients receiving treatments such as sodium-glucose cotransporter-2 (SGLT2) inhibitors, GLP-1 receptor agonists, and insulin. Vitamin E, with its antioxidant properties, is regarded as a first-line pharmacological option for managing MASH, especially when dietary and lifestyle interventions are insufficient. Antifibrotic agents can help prevent the progression of liver fibrosis and MASLD into fibrotic MASH. The role of pioglitazone, an anti-diabetic medication, in improving MASH histology in T2DM patients is well-documented, but concerns remain regarding potential side effects like weight gain, fluid retention, cancer risk, and bone fractures. Additional therapeutic targets for MASLD and MASH include G protein-coupled receptors (GPCRs), estrogen-related receptor alpha (ERRα), bone morphogenetic proteins (BMPs), and KLFs. Bariatric surgery, or weight loss surgery, is the most effective intervention for treating obesity and diabetes, as it reduces food absorption while influencing gut hormone secretion and metabolic function.

Growing research activities and multiple clinical trials for MASH, driven by the rapid surge in its prevalence due to rising obesity and type 2 diabetes rates, highlight an active drug development pipeline and an expanding market size. The large pool of patients and lucrative growth opportunities present attractive prospects for key players, further supported by ongoing preclinical studies aimed at advancing imaging techniques for MASH diagnosis, potentially eliminating the need for invasive biopsy-based histopathological confirmation. Furthermore, potential therapies are being investigated for the treatment of MASH, and it is safe to predict that the treatment space will significantly impact the MASH market during the forecast period. Moreover, the anticipated introduction of emerging therapies with improved efficacy and a further improvement in the diagnosis rate are expected to drive the growth of the MASH market in the 7MM. However, several factors may impede the growth of the MASH market. Lack of awareness and negligence in the early stages of MASH by physicians often lead to disease progression, culminating in irreversible damage where liver transplantation becomes the only viable option. Diagnosing advanced MASH typically requires procedures like liver biopsy, which are costly, invasive, and risky. Regulatory challenges also pose hurdles, as the FDA mandates achieving one MASH endpoint for approval, while the EMA's draft guidance requires efficacy in both endpoints, potentially delaying first-mover approvals in major European markets. Additionally, access to expensive MASH treatments may be limited in certain regions, further hindering patient adoption. Moreover, MASH treatment poses a significant economic burden and disrupts patients' overall well-being and QOL. Furthermore, MASH market growth may be offset by failures and discontinuation of emerging therapies, unaffordable pricing, market access and reimbursement issues, and a shortage of healthcare specialists. In addition, the undiagnosed, unreported cases and the unawareness about the disease may also impact MASH market growth.
