A \u2018Regulatory and Trial Update Workshop\u2019 was organized by the Society on Cachexia and Wasting Disorders (SCWD) in December 2024 in Washington, DC, focused on clinical trial endpoints, standards of care and recent advancements. This article provides a summary of the discussions that were held during the first day of the workshop. Despite ongoing research, effective therapies for cachexia remain limited. Existing treatments, such as nutritional supplements, progestins, anti\u2010inflammatories and anabolic agents, have shown mixed results, often improving appetite or lean mass without consistent functional benefits. Common muscle mass measurements, like CT scans of the L3 vertebra, are inadequate as primary endpoints because of biological variability and small effect sizes and because they do not necessarily translate into clinical benefit. Trials continue to face challenges in meeting regulatory requirements, which mandate improvements in both body composition and functional outcomes. Regulatory consensus emphasizes demonstrating clinically meaningful benefits in patient\u2010reported outcomes\/physical function and\/or morbidity\u2013mortality using validated instruments, adequate safety exposure, recognition that handgrip and weight alone are insufficient, feasibility in advanced disease, consideration of general activity measures, optional but informative body composition data and, for a pan\u2010cancer label, benefits across at least three distinct cancers. Patient\u2010centred endpoints, emphasizing real\u2010life functioning and social participation, are essential as patients prioritize daily activity and independence over isolated physical measures. Clinical trials presented during the meeting included the MENAC trial, which tested a multimodal intervention combining nutrition, exercise, anti\u2010inflammatory drugs and cancer therapy, achieved modest weight stabilization but no significant improvements in muscle mass or activity. In contrast, TCMCB07, an MC\u20104 receptor antagonist, demonstrated promising results in preclinical and early\u2010phase human studies, showing weight stabilization and improved caloric intake with good tolerability. ART27.13, a dual CB1\/CB2 receptor agonist, also demonstrated positive effects in appetite stimulation and weight stabilization. For S\u2010pindolol, which targets appetite and metabolism, Phase IIb\/III trials are to be initiated, following an earlier Phase II trial that showed improved muscle mass and muscle strength (hand grip strength). Future treatments must focus on integrating patient\u2010centred goals, therapeutic mechanisms and meaningful clinical outcomes.<\/jats:p>","DOI":"10.1002\/jcsm.70128","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T07:19:48Z","timestamp":1764227988000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Cachexia
