1156-P: Duodenal Mucosal Resurfacing (DMR) Combined with GLP-1 RA May Eliminate Insulin Therapy and Improve Metabolic Health in Type 2 Diabetes

Background: Duodenal mucosal resurfacing (DMR) is an endoscopic intervention in which the duodenal mucosa is ablated by hydrothermal energy. DMR improves glycemic control in type 2 diabetes (T2D) through altered metabolic signaling from the duodenum causing insulin sensitization. We studied the feasibility of eliminating insulin therapy in T2D by combining DMR with GLP-1r agonism (liraglutide) and lifestyle counseling. Methods: Single arm, single center study in 16 insulin treated T2D patients (HbA1c ≤64 mmol/mol; basal insulin Results: Enrolment has been completed and 9 patients have reached 6 months with 8/9 (89%) insulin-free and able to maintain glycemic control with improvement across multiple metabolic parameters (Table 1). Conclusion: Single endoscopic DMR, combined with liraglutide and lifestyle counseling, may effectively eliminate the need for insulin therapy in T2D while improving overall metabolic health. This treatment approach is a promising alternative that appears to shift insulin-treated T2D patients to a state of better overall metabolic health. Disclosure P. Smeele: None. A.C. van Baar: None.
