简要总结
This randomized controlled, two arms, investigator initiated, intervention study is aimed to examine an investigational approach in contrast to the clinical standard of 1:1 dose basal insulin conversion in an attempt to lower the incidence and/or duration of hyperglycemia after transition from insulin pump to multiple daily injections in adults with type 1 diabetes.
详细描述
Second generation long acting insulin, insulin degludec, has been shown to improve glycemic control and reduce hypoglycemia in patients with type 1 diabetes and insulin treated type 2 diabetes. However, it takes about 48 hours before glycemic benefits are noticeable. Therefore, transition from insulin pump to multiple daily injection using insulin degludec is associated with hyperglycemia during first 48 hours of transition. Considering this, this study proposes to evaluate an investigational strategy to improve glycemic control during transition from insulin pump to multiple daily injections using insulin degludec and insulin aspart.

研究组 & 干预措施
Standard of Care Transition
Stopping of insulin pump on the day of randomization and starting insulin degludec in 1:1 ratio (same units as total basal insulin on pump) and insulin Aspart for meals and corrections
干预措施: Multiple daily ijnection using Insulin Degludec and Insulin Aspart (Drug)
Inverstigational Transition
Administration of insulin degludec in 1:1 ratio (same units as total basal insulin on pump) on the day of randomization AND concomitant use of the insulin pump for 48 hours from transition, where insulin pump basal rate will be reduced by 50% during the first 24 hours from transition and by 75% during 24 to 48 hours from transition. Insulin pump will be disconnected after 48 hours from transition
干预措施: Multiple daily ijnection using Insulin Degludec and Insulin Aspart (Drug)
