Building on the previously proposed \"diabetes/disease-modifying drugs (DMDs)\" concept introduced through the SIMPLE framework, we propose a more mechanistically precise term: Disease-Modifying Anti-Diabetic Drugs (DMADDs). DMADDs are defined by four criteria: glucose-independent clinical benefit, durable organ-specific protection, mechanistic evidence of anti-inflammatory or anti-fibrotic activity, and sustained legacy effects or remission potential. Using these criteria, SGLT2i, GLP-1RA, and pioglitazone emerge as prototypical agents, while metformin, dipeptidyl peptidase-4 (DPP-4) inhibitors, insulin, and sulfonylureas do not meet the full threshold. We explicitly explain why metformin and DPP-4 inhibitors are excluded as DMADDs, situate the DMADD framework within the heterogeneity of type 2 diabetes and against what non-pharmacological interventions can achieve, and state the limitations of the proposal. Recent evidence reinforces this framework: the SOUL trial established cardiovascular superiority for oral semaglutide, extending disease-modifying properties beyond injectable formulations, while Phase 3 TRIUMPH data position retatrutide as an emerging triple-agonist candidate awaiting cardiovascular outcome data. The 2026 American Diabetes Association Standards of Care now recommend SGLT2i and GLP-1RA independent of baseline glycated hemoglobin (HbA1c), an institutional shift that mirrors the disease-interception logic proposed here. We argue that adopting the DMADD framework could reorient diabetes therapeutics from glycemic normalization toward early disease interception, potentially preserving β-cell function and expanding the clinical horizon toward remission. This terminology offers a unifying scaffold for future trials, regulatory classification, and clinical guidelines, redefining therapeutic success in type 2 diabetes beyond glucose control alone.</p>","PeriodicalId":9374,"journal":{"name":"Cardiovascular Diabetology","volume":"25 1","pages":""},"PeriodicalIF":15.6,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13520461/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148825320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
