Abstract
IN BRIEF Many patients with type 2 diabetes require high basal insulin doses, necessitating multiple injections, increasing patient burden, and resulting in reduced treatment adherence. This randomized, controlled, crossover trial compared the efficacy, safety, and patient-reported outcomes for a concentrated formulation of insulin degludec (200 units/mL) to those of insulin glargine in patients requiring high doses of basal insulin. By offering equivalent glycemic control while reducing the rate of confirmed hypoglycemia and the number of injections required for administration, insulin degludec 200 units/mL may be preferred by patients with type 2 diabetes who require high basal insulin doses.
