A Study to Compare LY2963016 to Lantus After a Single Dose to Participants With Type 1 Diabetes Mellitus
Condition: Diabetes Mellitus, Type 1
MeSH terms: Diabetes Mellitus; Diabetes Mellitus, Type 1
Intervention: LY2963016; Lantus
Intervention description: Single 0.3 U/kg dose administered subcutaneously; Single 0.3 U/kg dose administered subcutaneously
Intervention MeSH terms: Insulin Glargine
Phase: Phase 1
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Crossover Assignment
Masking: Double (Participant, Investigator)
Enrollment: 20.0
Sex: All
Minimum age: 18 Years
Maximum age: 60 Years
Healthy volunteers: No

Summary:

      The study involves a single injection of LY2963016 and a single injection of Lantus, on 2
      separate occasions in participants with type I diabetes. Following each dose, participants
      will undergo a glucose clamp which lasts for 42 hours each time. There will be at least 7
      days between the two periods, during which time there will be no study treatment, but
      participants will resume their regular therapy. The duration of this study can be up to 9.5
      weeks. The purposes of this study are to understand how the blood sugar lowering effect of
      LY2963016 compares to that of Lantus, and to determine how LY2963016 and Lantus are
      metabolized by participants with type I diabetes.
