Primary Outcome Measures:
  • Glucagon response to hypoglycemia [ Time Frame: 45 min ] [ Designated as safety issue: No ]
    Change in glucagon from before hypoglycemic clamp until after 45 min

Secondary Outcome Measures:
  • Catecholamine response to hypoglycemic [ Time Frame: 45 min ] [ Designated as safety issue: No ]
    Change in catecholamines from before hypolycemic clamp to 45 min

Enrollment: 28
Study Start Date: September 2010
Study Completion Date: December 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vildagliptin
Vildagliptin (50 mg BID) given for four weeks
Drug: Vildagliptin
Vildagliptin (50 mg BID) in four weeks
Other Name: Galvus

Detailed Description:

Vildagliptin (50 mg BID) or placebo is given as add-on to insulin treatment for four weeks in patients with type 1 diabetes. Then, a hypoglycemic clamp (2.5 mmol/l glucose) is undertaken with the determination of glucagon.
