Official title

Comparison of Insulin Degludec With Insulin Glargine U100 for Adults With Type 1 Diabetes Travelling Across Multiple Time Zones. A Pilot Study.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
