Study Arms:
- Fast-acting insulin aspart, default tmax setting (Type: EXPERIMENTAL): Participants will receive fast-acting insulin aspart using the iLet™ with default tmax setting (t65 = 65 minutes) in two different treatment periods in a cross-over manner. There will be 3 different cohorts with 2 treatment periods in each cohort.
- Fast-acting insulin aspart, non-default tmax setting (Type: EXPERIMENTAL): Participants will receive fast-acting insulin aspart using the iLet™ with non-default tmax setting (t50 = 50 minutes, t40 = 40 minutes or t30 = 30 minutes) in two different treatment periods in a cross-over manner. There will be 3 different cohorts with 2 treatment periods in each cohort.

Based on this trial design, predict the completion outcome and termination type (if applicable).
