Fast-acting insulin aspart (FA) can improve glycemic control in subjects with T1D. To further assess the effect and safety of FA, a multicenter, treat-to-target, 26-week trial (onset 8) randomized subjects with T1D to double-blind mealtime FA (n=342), or insulin aspart (IAsp; n=342), or open-label post-meal FA (n=341), each with insulin degludec. All available information regardless of treatment discontinuation was used for the evaluation of effect. Non-inferiority for the primary endpoint, change from baseline in A1C, was confirmed for mealtime and post-meal FA vs. IAsp (Figure). Mealtime FA was superior to IAsp for 1-h PPG increment using a standard meal test (ETD: -0.90 [-1.36;-0.45] mmol/L; -16.24 [-24.42;-8.05] mg/dL). Self-measured 1 hour PPG increment favored FA at breakfast (ETD: -0.58 [-0.99;-0.17] mmol/L; -10.43 [-17.85;-3.02] mg/dL) and across all meals (ETD: -0.48 [-0.74;-0.21] mmol/L; -8.58 [-13.35;-3.81] mg/dL). No significant differences were observed in treatment-emergent adverse events or overall rate of severe or confirmed hypoglycemic episodes (PG &lt;3.1 mmol/L [56 mg/dL]), but significantly less hypoglycemia was seen 3 to 4 h after meals with mealtime FA.

In summary, mealtime FA provided superior PPG control to IAsp with a similar overall improvement in A1C and no increased safety risk. These findings were consistent with those previously reported in subjects with T1D.
