In an open-label, single-center, randomized crossover study, 26 adults with type 2 diabetes (7 women and 19 men; (mean ± s.d.) age, 59 ± 11 years; baseline glycated hemoglobin (HbA1c), 75 ± 15 mmol mol^-1 (9.0% ± 1.4%)) underwent two 8-week periods to compare the CamAPS HX fully closed-loop app with standard insulin therapy and a masked glucose sensor (control) in random order, with a 2-week to 4-week washout between periods. The primary endpoint was proportion of time in target glucose range (3.9-10.0 mmol l^-1). Analysis was by intention to treat. Thirty participants were recruited between 16 December 2020 and 24 November 2021, of whomNature medicineFully automated closed-loop insulin delivery in adults with type 2 diabetes: an open-label, single-center, randomized crossover trial.PMC9873557CL-2020-14-801Daly ABHartnell SWilinska MEEvans MLNwokolo MCezar ABoughton CKHovorka RfalseFully automated closed-loop insulin delivery in adults with type 2 diabetes: an open-label, single-center, randomized crossover trial.In adults with type 2 diabetes, the benefits of fully closed-loop insulin delivery, which does not require meal bolusing, are unclear.
