Triple hormone receptor agonist retatrutide for metabolic dysfunction-associated steatotic liver disease: a randomized phase 2a trial.

ABSTRACT: Retatrutide is a novel triple agonist of the glucose-dependent insulinotropic polypeptide, glucagon-like peptide 1 and glucagon receptors. A 48-week phase 2 obesity study demonstrated weight reductions of 22.8% and 24.2% with retatrutide 8 and 12 mg, respectively. The primary objective of this substudy was to assess mean relative change from baseline in liver fat (LF) at 24 weeks in participants from that study with metabolic dysfunction-associated steatotic liver disease and ≥10% of LF. Here, in this randomized, double-blind, placebo-controlled trial, participants (n = 98) were randomly assigned to 48 weeks of once-weekly subcutaneous retatrutide (1, 4, 8 or 12 mg dose) or placebo. The mean relative change from baseline in LF at 24 weeks was -42.9% (1 mg), -57.0% (4 mg), -81.4% (8 mg), -82.4% (12 mg) and +0.3% (placebo) (all P < 0.001 versus placebo). At 24 weeks, normal LF (<5%) was achieved by 27% (1 mg), 52% (4 mg), 79% (8 mg), 86% (12 mg) and 0% (placebo) of participants. LF reductions were significantly related to changes in body weight, abdominal fat and metabolic measures associated with improved insulin sensitivity and lipid metabolism. The ClinicalTrials.gov registration is NCT04881760 .

Project description:ImportanceIn the US, hepatocellular carcinoma (HCC) has been the most rapidly increasing cancer since 1980, and metabolic dysfunction-associated steatotic liver disease (MASLD) is expected to soon become the leading cause of HCC.ObjectiveTo develop a prediction model for HCC incidence in a cohort of patients with MASLD.Design, setting, and participantsThis prognostic study was conducted among patients aged at least 18 years with MASLD, identified using diagnosis of MASLD using International Classification of Diseases, Ninth Revision (ICD-9) or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) diagnosis codes; natural language processing of radiology imaging report text, which identified patients who had imaging evidence of MASLD but had not been formally diagnosed; or the Dallas Steatosis Index, a risk equation that identifies individuals likely to have MASLD with good precision. Patients were enrolled from Kaiser Permanente Northern California, an integrated health delivery system with more than 4.6 million members, with study entry between January 2009 and December 2018, and follow-up until HCC development, death, or study termination on September 30, 2021. Statistical analysis was performed during February 2023 and January 2024.ExposureData were extracted from the electronic health record and included 18 routinely measured factors associated with MASLD.Main outcome and measuresThe cohort was split (70:30) into derivation and internal validation sets; extreme gradient boosting was used to model HCC incidence. HCC risk was divided into 3 categories, with the cumulative estimated probability of HCC 0.05% or less classified as low risk; 0.05% to 0.09%, medium risk; and 0.1% or greater, high risk.ResultsA total of 1 811 461 patients (median age [IQR] at baseline, 52 [41-63] years; 982 300 [54.2%] female) participated in the study. During a median (range) follow-up of 9.3 (5.8-12.4) years, 946 patients developed HCC, for an incidence rate of 0.065 per 1000 person-years. The model achieved an area under the curve of 0.899 (95% CI, 0.882-0.916) in the validation set. At the medium-risk threshold, the model had a sensitivity of 87.5%, specificity of 81.4%, and a number needed to screen of 406. At the high-risk threshold, the model had a sensitivity of 78.4%, a specificity of 90.1%, and a number needed to screen of 241.Conclusions and relevanceThis prognostic study of more than 1.8 million patients with MASLD used electronic health record data to develop a prediction model to discriminate between individuals with and without incident HCC with good precision. This model could serve as a starting point to identify patients with MASLD who may need intervention and/or HCC surveillance.

Project description:Multiple observation studies and meta-analysis have linked growth hormone (GH) deficiency with metabolic-dysfunction-associated steatotic liver disease (MASLD). No meta-analysis has analysed the efficacy and safety of GH therapy on different aspects of MASLD. We undertook this meta-analysis to address this gap in knowledge. Electronic databases were searched for RCTs involving patients with MASLD receiving GH therapy. Primary outcome was to evaluate changes in radiologic measures of MASLD (magnetic resonance spectroscopy (MRS) and ultrasonography) and liver enzymes. Secondary outcomes were to evaluate alterations in body composition parameters [dual-energy X-ray absorptiometry (DXA)], lipids, glycaemia and side effects. From initially searched 1047 articles, data from three RCTs (120 patients) which fulfilled all criteria were analysed. After 6 months of GH therapy in MASLD, the per cent reduction in intrahepatic lipid (MRS) was significantly higher with GH as compared to placebo [MD -5.85% (95%CI:-11.41- -0.30); P = 0.04; I2 = 63%]. Visceral adipose tissue (VAT) area reduction (DXA) was significantly higher with GH [MD-9.94 cm2 (95%CI:-19.04- -0.84); P = 0.03; I2 = 0%]. Serum insulin-like growth factor-1 (IGF-1) was significantly raised in MASLD patients receiving GH as compared to placebo [MD +166.86 ng/ml (95%CI: 79.19-254.53); P < 0.0.001; I2 = 90%]. High-sensitivity C-reactive protein (hsCRP) was significantly lower in patients receiving GH [MD -0.89 mg/L (95%CI:-1.40--0.38); P = 0.0.0006; I2 = 0%]. Patients receiving GH had similar changes in triglycerides [MD-1.06 mg/L (95%CI:-20.45-18.34); P = 0.91; I2 = 15%] and fasting glucose [MD -0.56 mg/L (95%CI:-4.67-3.55); P = 0.79; I2 = 39%]. Gamma-glutamyl transpeptidase was significantly lower in patients receiving GH [MD -7.86 U/L (95%CI:-12.46--3.27); P = 0.0008; I2 = 0%]. No increase in new-onset hypothyroidism was noted [OR 5.49 (95%CI: 0.25-121.18); P = 0.28]. Short-term 6-month GH therapy in MASLD is associated with a significant reduction in intrahepatic lipid content, visceral adiposity, GGT and hsCRP without any increased occurrence of dysglycaemia or hypothyroidism.
