CLINICAL RATIONALE
Metabolic dysfunction-associated steatotic liver disease (MASLD)/Metabolic dysfunction-associated steatohepatitis (MASH) |
Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed non-alcoholic fatty liver disease (NAFLD), is defined as steatotic liver disease (SLD) in the presence of one or more cardiometabolic risk factor(s) and the absence of harmful alcohol intake. SLD occurs when your body begins storing fat in your liver. Some fat in your liver is normal, but when more than 5 to 10% of the liver's weight is fat, it is classified as steatosis. MASLD and alcoholic liver disease (ALD), (alcohol intake >50 g/day for females and >60 g/day for males) comprise the most common causes of SLD. A new category, requiring further characterization, termed MetALD, describes those with MASLD who consume greater amounts of alcohol (20-50 g/day for females and 30-60 g/day for males, respectively), but do not meet the criteria for ALD. The history of alcohol consumption is an important factor as the current drinking pattern may not necessarily reflect previous drinking behavior. Importantly, despite sharing the same prevalence of cardiometabolic risk factors, MetALD is associated with a higher risk of all-cause mortality, underpinning MetALD as a distinct subclass of SLD with poorer prognosis. Therefore, diagnostic and treatment recommendations provided for MASLD cannot be extended to the MetALD population.(2,5,10,12) The spectrum of MASLD includes steatosis, metabolic dysfunction-associated steatohepatitis (MASH, previously NASH), fibrosis, cirrhosis and MASH-related hepatocellular carcinoma (HCC). With MASH, fat buildup progresses to inflammation, then tissue damage and scarring (fibrosis). Metabolic dysfunction-associated steatohepatitis (MASH) is inflammation of the liver caused by excess fat cells in it (steatotic liver disease). MASH is characterized by histological features of hepatocellular ballooning and lobular inflammation. Chronic inflammation causes progressive liver damage. MASL refers to the presence of MASLD in the absence of steatohepatitis.(2,10,12) Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease, and its prevalence will likely continue to rise. Often, MASLD has no symptoms. When symptoms do occur, they may include fatigue, weakness, weight loss, loss of appetite, nausea, abdominal pain, spider-like blood vessels, yellowing of the skin and eyes (jaundice), itching, fluid buildup and swelling of the legs (edema) and abdomen (ascites), and mental confusion. MASLD is initially suspected if blood tests show high levels of liver enzymes with an absence of chronic alcohol intake. However, other liver diseases are first ruled out through additional tests (e.g., Wilson's disease, hepatitis).(2,3,4) The presence of MASLD is tightly linked to type 2 diabetes (T2D), obesity and other cardiometabolic risk factors. Studies suggest that one-third to two-thirds of people with type 2 diabetes have MASLD. Research suggests that MASLD is present in up to 75% of people who are overweight and in more than 90% of people who have severe obesity. MASLD is associated with an increased risk of cardiovascular events, chronic kidney disease, hepatic and extrahepatic malignancies, and liver-related outcomes, including liver failure and hepatocellular carcinoma (HCC).(2,10,12) The following are the adult cardiometabolic risk factors (at least 1 out of 5) in the definition of MASLD:(10,12)
The 2021 AACE and 2023 AASLD practice guidelines recommend the following:(2,4)
Initial evaluation in persons with suspected or incidental finding of hepatic steatosis on imaging should include investigations to exclude competing causes for hepatic steatosis and liver disease (e.g., hepatitis B and C serology, antimitochondrial antibodies, antinuclear antibodies, anti–smooth muscle antibodies, serum ferritin, alpha 1 antitrypsin, and evaluation for metabolic syndrome). It is important to note that normal values provided by most laboratories are higher than what should be considered normal in MASLD, in which a true normal alanine aminotransferase (ALT) ranges from 29 to 33 U/L in men and from 19 to 25 U/L in women.(2,4,5) The American Gastroenterology Association guidelines recommend the following best practice advice in the diagnosis of MASH/MASLD:(7)
NITs (non-invasive tests) derived from clinical variables can estimate of the presence of advanced fibrosis. Several have been developed (e.g., FIB-4, NAFLD/MASLD Fibrosis Score, AST Platelet Ratio Index); however, FIB-4 is the most validated. FIB-4 is calculated using a simple algorithm based upon age, ALT, AST, and platelet count and outperforms other calculations in its ability to identify patients with a low probability of advanced fibrosis. The FIB-4 index can be calculated from age and three parameters obtained in routine laboratory assessments: alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet count. A change in FIB-4 status category from low risk (<1.3) to intermediate risk (1.3–2.67) to high risk (>2.67) may be used to assess clinical progression. Although FIB-4 is statistically inferior to other serum-based fibrosis markers such as the Enhanced Liver Fibrosis (ELF) panel, FIBROSpect II, and imaging-based elastography methods to detect advanced fibrosis, FIB-4 is still recommended as a first-line assessment for general practitioners and endocrinologists based on its simplicity and minimal added cost.(2,6,7) Those who may have a moderate or high risk of advanced disease based on FIB-4 should undergo secondary risk assessment. Vibration-controlled transient elastography (VCTE) (e.g., FibroScan) is the most commonly used method to assess liver stiffness and can be used to exclude significant hepatic fibrosis. Magnetic resonance elastography (MRE) is more sensitive than VCTE in the detection of fibrosis stage greater than 2 and is considered to be the most accurate noninvasive imaging-based biomarker of fibrosis in NAFLD/MASLD. Although MRE is not a first-line approach to risk stratification in a patient with NAFLD/MASLD, it can be an important tool if clinical uncertainty exists, if there is a need for concomitant cross-sectional imaging, or when other elastography techniques are unavailable. Among patients with cirrhosis, a baseline liver stiffness measure (LSM) by MRE predicts future risk of incident hepatic decompensation and death. An LSM by MRE greater than or equal to kPa is suggestive of cirrhosis. Controlled Attenuation Parameter (CAP) as a point-of-care technique may also be used to identify steatosis. A liver biopsy is the optimal approach to confirm the diagnosis and stage of the severity of liver fibrosis. However, it is recognized that this may not be feasible or acceptable to several individuals.(2,4,7) Incorporating pharmacological treatment with agents known to reverse NASH/MASH is crucial to more effectively prevent progression to cirrhosis. Treatment guidelines for individuals with type 2 diabetes (T2D) and NASH/MASH focus on managing hyperglycemia and/or obesity alongside NASH/MASH, particularly if clinically significant fibrosis (stage F2 or higher) is present, to avert the development of cirrhosis. Some medications that are effective for treating T2D and NASH/MASH, such as pioglitazone and GLP-1 receptor agonists (RAs), also contribute to reducing cardiovascular disease (CVD), which is the leading cause of death in this group. Two antidiabetic drugs, pioglitazone and GLP-1 RAs, have shown safety and effectiveness in reversing NASH/MASH in individuals with obesity, prediabetes, or T2D, though they are not yet FDA approved for this purpose. While weight loss can reverse NASH/MASH, typically in relation to the extent of weight loss, the ability to halt fibrosis progression is less consistent and can vary significantly among individuals.(2,4) The 2024 European Association for the Study of the Liver (EASL), European Association for the Study of Diabetes (EASD) and European Association for the Study of Obesity (EASO) guidelines suggest in adults with MASLD, lifestyle modification which includes weight loss, dietary changes, physical exercise and discouraging alcohol consumption. In addition, they recommend optimal management of comorbidities, including use of incretin-based therapies (e.g., semaglutide, tirzepatide) for T2D or obesity, if indicated. Bariatric surgery is also an option in individuals with MASLD and obesity. If locally approved and dependent on the label, adults with non-cirrhotic MASH and significant liver fibrosis (stage greater than or equal to 2) should be considered for a MASH-targeted treatment with resmetirom, which demonstrated histological effectiveness on steatohepatitis and fibrosis with an acceptable safety and tolerability profile. No MASH-targeted pharmacotherapy can currently be recommended for the cirrhotic stage. Management of MASH-related cirrhosis includes adaptations of metabolic drugs, nutritional counselling, surveillance for portal hypertension and HCC, as well as liver transplantation in decompensated cirrhosis.(10) While an initial study with liraglutide indicated a histological benefit in MASH, drugs that are being developed for MASH now include semaglutide, and dual GLP1-GIP (e.g., tirzepatide), dual GLP1-glucagon (e.g., cotadutide, survodutide, efinopegdutide) or triple GLP1-GIP-glucagon (e.g., retatrutide) agonists. The largest available trial on semaglutide in MASH (vs. placebo over an 18-month treatment period) demonstrated resolution of steatohepatitis but no fibrosis improvement. A large registrational, phase III study with semaglutide is ongoing. Tirzepatide (GLP1/GIP RA) has been shown to significantly reduce both liver and visceral fat in those with T2D, in association with major weight loss (comparable to bariatric surgery), and promising results on steatohepatitis resolution from a phase II study in MASH have been communicated.(10) |
Efficacy |
Resmetirom is a once daily, oral, thyroid hormone receptor (THR)-beta selective agonist designed to target key underlying causes of NASH in the liver. Hypothyroidism is associated with NAFLD/NASH; specifically, intrahepatic hypothyroidism drives lipotoxicty in preclinical models. Agonists of thyroid hormone receptor (THR)-beta, which is primarily found in the liver, can promote lipophagy, mitochondrial biogenesis and mitophagy, stimulating increased hepatic fatty acid β-oxidation, and thereby decreasing the burden of lipotoxic lipids, while promoting low-density lipoprotein (LDL) uptake and favorable effects on lipid profiles.(8) The efficacy of Rezdiffra was evaluated based on an efficacy analysis at Month 12 in Trial 1 (NCT03900429), a 54-month, randomized, double-blind, placebo-controlled trial. Enrolled patients had metabolic risk factors and a baseline or recent liver biopsy showing NASH with fibrosis stage 2 or 3 and a NAFLD Activity Score (NAS) of at least 4. Efficacy determination was based on the effect of Rezdiffra on resolution of steatohepatitis without worsening of fibrosis and one stage improvement in fibrosis without worsening of steatohepatitis, on post-baseline liver biopsies collected at 12 months. The month 12 analysis included 888 F2 and F3 (at eligibility) patients randomized 1:1:1 to receive placebo (n = 294), Rezdiffra 80 mg once daily (n = 298), or Rezdiffra 100 mg once daily (n = 296), in addition to lifestyle counseling on nutrition and exercise. Patients were on stable doses of medications for diabetes, dyslipidemia, and hypertension.(1) Demographic and baseline characteristics were balanced between treatment and placebo groups. Overall, the median age of patients at baseline was 58 (51 to 65) years, 56% were female, 21% were Hispanic, 89% were White, 3% were Asian, and 2% were Black or African American. Median body mass index (BMI) was 35 (31 to 40) kg/m2 and median body weight was 99 (85 to 114) kg.(1) Overall, 966 patients formed the primary analysis population (322 in the 80-mg resmetirom group, 323 in the 100-mg resmetirom group, and 321 in the placebo group). NASH resolution with no worsening of fibrosis was achieved in 25.9% of the patients in the 80-mg resmetirom group and 29.9% of those in the 100-mg resmetirom group, as compared with 9.7% of those in the placebo group. Fibrosis improvement by at least one stage with no worsening of the NAFLD activity score was achieved in 24.2% of the patients in the 80-mg resmetirom group and 25.9% of those in the 100-mg resmetirom group, as compared with 14.2% of those in the placebo group. The change in low-density lipoprotein cholesterol levels from baseline to week 24 was -13.6% in the 80-mg resmetirom group and -16.3% in the 100-mg resmetirom group, as compared with 0.1% in the placebo group. Both the 80-mg dose and the 100-mg dose of resmetirom were superior to placebo with respect to NASH resolution and improvement in liver fibrosis by at least one stage.(1,9) |
