{Abstract}: <B>OBJECTIVE: </B>This was a randomized, double-blind, placebo-controlled study to assess the effects of pemvidutide, a glucagon-like peptide-1 (GLP-1)/glucagon dual receptor agonist, on liver fat content (LFC) in subjects with metabolic dysfunction-associated steatotic liver disease (MASLD).<BR><B>METHODS: </B>Subjects with a BMI ≥28.0 kg/m2 and LFC ≥10% by magnetic resonance imaging-proton density fat fraction were randomized 1:1:1:1 to pemvidutide at 1.2 mg, 1.8 mg, or 2.4 mg, or placebo administered subcutaneously once weekly for 12 weeks. Participants were stratified according to a diagnosis of type 2 diabetes mellitus (T2DM). The primary efficacy endpoint was relative reduction (%) from baseline in LFC after 12 weeks of treatment.<BR><B>RESULTS: </B>94 subjects were randomized and dosed. Median baseline BMI and LFC across the study population were 36.2 kg/m2 and 20.6%; 29% of subjects had T2DM. At Week 12, relative reductions in LFC from baseline were (1.2 mg) 46.6% [95% CI -63.7 to -29.6], (1.8 mg) 68.5% [95% CI -84.4 to -52.5], and (2.4 mg) 57.1% [95% CI -76.1 to -38.1] versus 4.4% [95% CI -20.2 to 11.3] in placebo subjects (p <0.001 vs. placebo, all treatment groups), with 94.4% and 72.2% of subjects achieving 30% and 50% reductions in LFC and 55.6% achieving normalization (≤5% LFC) at the 1.8 mg dose. Maximal responses for weight loss (-4.3%; p <0.001), alanine aminotransferase (-13.8 IU/L; p = 0.029), and corrected cT1 (-75.9 ms; p = 0.002) were all observed at the 1.8 mg dose. Pemvidutide was well-tolerated at all doses with no severe or serious adverse events.<BR><B>CONCLUSIONS: </B>In subjects with MASLD, weekly pemvidutide treatment yielded significant reductions in LFC, markers of hepatic inflammation, and body weight compared to placebo.<BR><B>UNASSIGNED: </B>MASLD, and MASH, are strongly associated with overweight and obesity and it is believed that the excess liver fat associated with obesity is an important driver of these diseases. Glucagon-like peptide-1 receptor (GLP-1R) agonists elicit weight loss through centrally and peripherally mediated effects on appetite. Unlike GLP-1R agonists, glucagon receptor (GCGR) agonists act directly on the liver to stimulate fatty acid oxidation and inhibit lipogenesis, potentially providing a more potent mechanism for liver fat content (LFC) reduction than weight loss alone. This study demonstrated the ability of once-weekly treatment with pemvidutide, a dual GLP-1R/GCGR agonist, to significantly reduce LFC, hepatic inflammatory activity, and body weight, suggesting that pemvidutide may be an effective treatment for both MASH and obesity.<BR><B>BACKGROUND: </B>NCT05006885.
