Fourteen T2D subjects in a real-world practice setting, uncontrolled on oral/injectable combo therapy (mean A1C 9%), received inhaled human insulin (INH-Afrezza), added to current therapy and titrated weekly for up to 12 weeks. A1C and 2-week continuous glucose monitoring (CGMS) profiles (Libre Pro) were collected at baseline and after 3 months.

All subjects started INH 4 units (u) prior to each meal and titrated rapidly to 12 u/meal over 9 days. Thereafter, INH was adjusted for each meal once weekly, based on PPG at 2-2.5 hours measured on days 1 and 2 of each week, as follows: Add 4 u if PPG > 160 mg/dl, no change if PPG 90-160 mg/dl and decrease by 4 u if PPG < 90 mg/dl. More than 1/2 of subjects were taking basal insulin.

Addition of the only available inhaled ultra-rapid rapid mealtime insulin (Afrezza) lowered glucose safely in patients with T2D inadequately controlled on oral and/or injectable therapy. Initiation and titration, following a simple algorithm, resulted in significant A1c reduction (-1.6%, p<.0001), a decrease in mean daily glucose (∼50 mg/dl), and a 76% increase in time-in-range on CGMS, with no significant increase in hypoglycemia (Time<70 mg/dL). No severe hypoglycemia occurred. Final mealtime Afrezza doses achieved were 18, 16 and 20 u at breakfast, lunch, dinner respectively.
