Review
This plain-language review provides an educational overview of survodutide, an investigational medication being studied for the treatment of obesity and metabolic dysfunction-associated steatohepatitis (MASH). The review explains how survodutide works mechanistically and summarizes findings from clinical trials, including key health outcomes and reported side effects observed in trial participants. The authors contextualize survodutide within the broader landscape of obesity and MASH as linked metabolic diseases, noting that both conditions involve dysregulation of energy use and storage, and that they frequently co-occur with other metabolic health conditions. Standard-of-care recommendations such as dietary changes and physical activity are acknowledged, alongside pharmacological and surgical interventions. As a review article rather than an original trial, this paper does not generate new primary data; its conclusions are derived from synthesizing existing clinical trial results. Limitations include the non-approved status of survodutide, the inherent scope constraints of a plain-language review format, and the potential for selective reporting of trial findings. The evidence supporting survodutide's effects ultimately depends on the quality and size of the underlying clinical trials referenced, which are not individually appraised within this summary piece.

This review synthesizes evidence from randomized controlled trials and high-quality meta-analyses on approved and investigational obesity medications, examining their effects beyond weight loss alone. Medications reviewed include phentermine-topiramate, naltrexone-bupropion, GLP-1 receptor agonists (liraglutide, semaglutide), and newer multiagonist agents (tirzepatide, survodutide, mazdutide, retatrutide, cagrilintide-semaglutide, and amycretin). The authors evaluated impacts across a broad range of obesity-related comorbidities, including type 2 diabetes, metabolic dysfunction-associated steatotic liver disease, chronic kidney disease, heart failure, cardiovascular disease, obstructive sleep apnea, polycystic ovary syndrome, osteoarthritis, muscle mass, depression, quality of life, food cravings, binge-eating disorders, substance use disorders, and neurodegenerative diseases. The review concludes that GLP-1-based and multiagonist therapies demonstrate beneficial effects across these conditions. Notably, the authors report that while many benefits appear to be mediated through weight reduction, accumulating evidence suggests weight loss-independent mechanisms, particularly for GLP-1 receptor agonist-based therapies. Key limitations include its reliance on synthesized rather than primary data and variability in evidence quality across the individual conditions reviewed.

This narrative review examines the rapidly evolving landscape of obesity pharmacotherapy, moving beyond currently approved injectable GLP-1 receptor agonists (GLP-1RAs). The authors contextualize the global obesity burden—affecting over 2 billion adults—and acknowledge the transformative but limited success of existing GLP-1-based therapies, citing weight loss plateaus, high inter-individual variability, and weight regain upon discontinuation as key unresolved challenges. The review synthesizes emerging drug classes including: oral GLP-1 agonists (e.g., orforglipron) aimed at improving global accessibility; multi-receptor agonists such as triple GLP-1/GIP/glucagon agonists (e.g., retatrutide, reportedly achieving 20–24% weight reduction) and dual GLP-1/glucagon agonists (e.g., survodutide, mazdutide) with potential benefits in metabolic-associated steatotic liver disease; novel dosing strategies via GLP-1/GIP combination agents (e.g., maridebart cafraglutide); amylin pathway agents (e.g., cagrilintide, amycretin); lean-mass-preserving agents (e.g., bimagrumab); and precision approaches for monogenic obesity (e.g., setmelanotide). The authors call for phenotype-stratified trials, long-term safety data, pediatric research, and equitable implementation. As a review, it does not present original trial data and is inherently subject to selection and interpretation bias.

This paper is a narrative review examining survodutide, a dual GLP-1 and glucagon receptor agonist, in the context of obesity, metabolic dysfunction-associated steatohepatitis (MASH), and related metabolic conditions including type 2 diabetes and cardiovascular disease. The authors summarize survodutide's proposed mechanism of action — encompassing appetite suppression, improved glucose metabolism, and increased energy expenditure — and compare its dual-agonist profile against single-target incretin-based therapies such as GLP-1 receptor agonists alone. The review synthesizes findings from early-phase clinical trials, which the authors report showed significant weight loss and improvements in metabolic markers. Safety and tolerability are also discussed, alongside broader cardiovascular and metabolic benefits suggested by preliminary data. The authors acknowledge that the evidence base remains limited, stressing that long-term safety, durability of effect, patient-specific responses, and cost-effectiveness have not yet been fully established. Ongoing and future trials are highlighted as essential for clarifying survodutide's clinical role. As a review article, this paper does not generate new primary data, and its conclusions are bounded by the early-stage evidence available at the time of writing.

This review examines the landscape of next-generation glucagon-like peptide-1 (GLP-1)-based therapeutics in clinical development for type 2 diabetes and obesity, building on the established success of semaglutide and tirzepatide. The authors survey a broad range of investigational agents that target multiple gastro-entero-pancreatic hormone receptors simultaneously — including GIP, glucagon, amylin, and peptide YY receptors — to produce synergistic effects on energy intake, storage, and expenditure. Specific agents discussed include maridebart cafraglutide (GLP-1 agonism/GIP antagonism), survodutide and mazdutide (GLP-1/glucagon coagonists), cagrilintide combined with semaglutide (CagriSema), amycretin (amylin/GLP-1 dual agent), and retatrutide (GIP/GLP-1/glucagon triple agonist). The review also highlights the emergence of oral small-molecule GLP-1 receptor agonists such as danuglipron and orforglipron, which resist enzymatic degradation and may improve patient convenience. The paper does not present original clinical trial data; it synthesizes existing preclinical and clinical development evidence. As a narrative review, it does not meta-analytically pool outcomes, and the included agents are largely at Phase 1–3 stages, meaning long-term efficacy and safety data remain limited.

This review paper examines survodutide, a dual glucagon and glucagon-like peptide-1 (GLP-1) receptor agonist, and its potential role in cardiometabolic disease management. The authors synthesize findings from Phase 2 clinical trials, which reported weight loss of up to 18.7% and HbA1c reductions of up to -1.71%, suggesting survodutide may outperform semaglutide on weight outcomes while achieving comparable glycemic control. The paper also discusses Phase 2 evidence showing improvements in liver fat content and fibrosis markers in patients with metabolic dysfunction-associated steatohepatitis (MASH), alongside proposed mechanisms for cardiovascular benefit, including reductions in visceral and epicardial adiposity, systemic inflammation, and fibrosis-related remodeling. Early signals of renal benefit are noted. Limitations acknowledged include higher rates of gastrointestinal adverse events and modest heart rate increases compared to some comparators, contributing to elevated discontinuation rates. The authors emphasize that definitive evidence from cardiovascular outcomes trials is still lacking, with the ongoing SYNCHRONIZE-CVOT trial expected to address this gap. As a narrative review relying primarily on Phase 2 data, the paper does not establish long-term cardiovascular efficacy or safety.

This review article, published as part of a special issue on GLP-1 receptor agonists, examines the emerging class of glucagon receptor (GCGR)-based multi-agonist drugs as pharmacological treatments for obesity. The authors discuss several investigational agents — mazdutide, pemvidutide, survodutide, and retatrutide — all of which are in advanced stages of clinical development. According to the review, early-phase trial data for these agents suggest they can produce significant weight loss, potentially exceeding that seen with currently available therapies. The article also highlights their potential to address obesity-related comorbidities such as type 2 diabetes and cardiovascular disease, and notes that some agents are being evaluated in cardiovascular outcomes trials. The authors position GCGR-based multi-agonists as potentially important additions to future obesity treatment guidelines, particularly for patients who have not responded adequately to existing medications or lifestyle interventions. Key limitations and considerations noted include cost, access, and the need for long-term safety data as these drugs progress toward regulatory approval. As a narrative review, this article synthesizes existing trial data but does not generate new primary evidence.

This review paper provides a comprehensive overview of the current and emerging pharmacological landscape for metabolic dysfunction-associated steatohepatitis (MASH), the progressive inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD). The authors describe MASH as a growing global health burden, closely tied to obesity and type 2 diabetes, and carrying significant risks of cirrhosis, hepatocellular carcinoma, and liver failure. The review synthesizes evidence from advanced-stage clinical trials evaluating several therapeutic classes, including incretin-based therapies (GLP-1 receptor agonists, dual, and triple agonists such as semaglutide, tirzepatide, and survodutide), metabolic modulators (PPAR agonists like lanifibranor, FGF21 analogues like pegozafermin, and thyroid hormone receptor-beta agonists like resmetirom), and novel agents such as fatty acid synthase inhibitors. The authors note that regulatory endpoints currently rely on histological assessment, while noninvasive biomarkers and personalized approaches are gaining traction. Genetic factors, such as PNPLA3 polymorphisms, and artificial intelligence are highlighted as emerging tools for patient stratification and trial design. Key limitations acknowledged include unresolved questions about treatment duration, response heterogeneity, long-term adherence, and the evolving definition of therapeutic success.
The Journal of clinical investigation · Jul 2025DOI ↗ Review
This review article provides a comprehensive overview of approved and emerging hormone-based anti-obesity medications (AOMs), situating them within the broader context of obesity as a complex, chronic, global disease. The authors summarize the current regulatory landscape, noting that the GLP-1 receptor agonists (GLP-1RAs) liraglutide and semaglutide have received FDA and EMA approval for weight management. The review also covers pipeline agents, including oral GLP-1RAs (semaglutide, danuglipron, orforglipron), the amylin receptor agonist cagrilintide (alone and in combination with semaglutide), and dual agonists such as tirzepatide (GIP/GLP-1), survodutide, mazdutide, and pemvidutide (GLP-1R/GCGR). The authors highlight tirzepatide's placebo-subtracted weight reduction of 17.8% in a 72-week RCT and retatrutide's (a GLP-1R/GCGR/GIPR tri-agonist) placebo-subtracted reduction of 22.1% in a 48-week phase-II trial. The review cautions that long-term safety and cardiovascular outcome data for many of these agents remain incomplete. As a narrative review, it does not conduct original research or meta-analysis, and conclusions are limited by the quality and heterogeneity of the underlying primary studies it synthesizes.
