Insulin icodec is a basal insulin in development for once-weekly (OW) dosing. The aim of this study was to compare the hypoglycemia frequency and response after icodec vs. insulin glargine U100 (IGlar) overdosing. In a randomized, open-label, two-period crossover trial, 43 individuals with T2D on basal insulin±metformin (mean±SD age 56±9 yrs, HbA1c 7.2±0.7%) received OW icodec for 6 weeks and once-daily IGlar for 12 days at equimolar total weekly doses based on the individual daily run-in IGlar dose (mean 30±14 U) titrated to a fasting SMPG target of 80-130 mg/dL. Once at steady state, double (DD) and triple (TD) doses of icodec and IGlar were followed by hypoglycemia induction 44 h (icodec) or 7 h (IGlar) post-dose (expected time of maximum glucose-lowering effect) : First, euglycemia was maintained at 100 mg/dL by variable i.v. glucose. Then, PG was allowed to decrease to a nadir of no less than 45 mg/dL maintained for 15 min. Euglycemia was restored by constant i.v. glucose. Hypoglycemic symptom score (HSS) and counterregulatory hormones were assessed at PG 100 mg/dL and at predefined PG levels until nadir PG. For DD, clinically significant hypoglycemia (PG In conclusion, a DD or TD of once-weekly insulin icodec does not lead to increased risk of hypoglycemia compared to once-daily IGlar. During hypoglycemia, a comparable symptomatic response and a moderately greater endocrine response were seen for icodec vs. IGlar. Disclosure E.Svehlikova: n/a. K.Niss arfelt: Employee; Novo Nordisk.
