    Consensus Report on Glucagon-Like Peptide-1 Receptor Agonists as Adjunctive Treatment for Individuals With Type 1 Diabetes Using an Automated Insulin Delivery System
    (Sage, 2024-11-08) Shah, Viral N.; Peters, Anne L.; Umpierrez, Guillermo E.; Sherr, Jennifer L.; Akturk, Halis Kaan; Aleppo, Grazia; Bally, Lia; Cengiz, Eda; Cinar, Ali; Dungan, Kathleen; Fabris, Chiara; Jacobs, Peter G.; Lal, Rayhan A.; Mader, Julia K.; Masharani, Umesh; Prahalad, Priya; Schmidt, Signe; Zijlstra, Eric; Ho, Cindy N.; Ayers, Alessandra T.; Tian, Tiffany; Aaron, Rachel E.; Klonoff, David C.; Medicine, School of Medicine
    With increasing prevalence of obesity and cardiovascular diseases, there is a growing interest in the use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) as an adjunct therapy in type 1 diabetes (T1D). The GLP-1RAs are currently not approved by the US Food and Drug Administration for the treatment of T1D in the absence of randomized controlled trials documenting efficacy and safety of these agents in this population. The Diabetes Technology Society convened a series of three consensus meetings of clinicians and researchers with expertise in diabetes technology, GLP-1RA therapy, and T1D management. The project was aimed at synthesizing current literature and providing conclusions on the use of GLP-1RA therapy as an adjunct to automated insulin delivery (AID) systems in adults with T1D. The expert panel members met virtually three times on January 17, 2024, and April 24, 2024, and August 14, 2024, to discuss topics ranging from physiology and outcomes of GLP-1RAs in T1D to limitations of current sensors, algorithms, and insulin for AID systems. The panelists also identified research gaps and future directions for research. The panelists voted to in favor of 31 recommendations. This report presents the consensus opinions of the participants that, in adults with T1D using AID systems, GLP-1RAs have the potential to (1) provide effective adjunct therapy and (2) improve glycemic and metabolic outcomes without increasing the risk of severe hypoglycemia or diabetic ketoacidosis.

    The Use of Continuous Glucose Monitoring to Diagnose Stage 2 Type 1 Diabetes
    (Sage, 2025-05-30) Mader, Julia K.; Wong, Jenise C.; Freckmann, Guido; Garcia-Tirado, Jose; Hirsch, Irl B.; Johnson, Suzanne Bennett; Kerr, David; Kim, Sun H.; Lal, Rayhan; Montaser, Eslam; O'Donnell, Holly; Pleus, Stefan; Shah, Viral N.; Ayers, Alessandra T.; Ho, Cindy N.; Biester, Torben; Dovc, Klemen; Farrokhi, Farnoosh; Fleming, Alexander; Gillard, Pieter; Heinemann, Lutz; López-Díez, Raquel; Maahs, David M.; Mathieu, Chantal; Quandt, Zoe; Rami-Merhar, Birgit; Wolf, Wendy; Klonoff, David C.; Medicine, School of Medicine
    This consensus report evaluates the potential role of continuous glucose monitoring (CGM) in screening for stage 2 type 1 diabetes (T1D). CGM offers a minimally invasive alternative to venous blood testing for detecting dysglycemia, facilitating early identification of at-risk individuals for confirmatory blood testing. A panel of experts reviewed current evidence and addressed key questions regarding CGM's diagnostic accuracy and screening protocols. They concluded that while CGM cannot yet replace blood-based diagnostics, it holds promise as a screening tool that could lead to earlier, more effective intervention. Metrics such as time above range >140 mg/dL could indicate progression risk, and artificial intelligence (AI)-based modeling may enhance predictive capabilities. Further research is needed to establish CGM-based diagnostic criteria and refine screening strategies to improve T1D detection and intervention.
