Study Summary

The purpose of the proposed study is to compare insulin Degludec \[TRESIBA® (insulin degludec injection)\] with insulin Glargine U100 \[Lantus® (insulin glargine injection)\] to determine the basal insulin of choice for adults with type 1 diabetes (T1D) who fly non-stop across multiple time zones. With the introduction of Degludec as basal insulin for T1D and the opportunity to vary time of injection between 8 and 40 hours, the use of Degludec as a basal insulin may make it easier for both people living with T1D and diabetologists to plan long-haul travel compared to the use of existing basal insulins when crossing multiple time zones.The study hypothesis is that once daily Degludec as the basal insulin will provide better glycemic control for people with type 1 diabetes on multiple daily injections who are traveling non-stop across multiple time zones than once daily Glargine U100.

Primary Outcome

Time in range (70-140 mg/dl) \[percentage of glucose readings or hours per day\] by continuous glucose monitoring (CGM) during the initial 24 hours local time (starting within 2 hours after arriving) in Newark, NJ after flying 9-10 hours West to East (from Honolulu, HI) and after the return journey from Newark to Honolulu (flying East to West).
