The ability of glucagon-like peptide 1 to enhance beta-cell responsiveness to I.v. glucose is impaired in patients with type 2 diabetes mellitus compared with healthy individuals. We investigated whether 4 weeks of near-normalisation og blood glucose improves the potentiation of glucose-stimulated insulin secretion by GLP-1

Condition Intervention
Diabetes Mellitus Type 2
Drug: glucagon-like peptide-1
Drug: Saline

Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Single Blind (Subject)

Further study details as provided by Hvidovre University Hospital:

Primary Outcome Measures:
  • insulin secretion rate (ISR) were derived by deconvolution of c-peptide. ISR is expressed as pmol/kg/min [ Time Frame: 180 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The calculated ISR values was plotted against the ambient plasma glucose. The slopes of this linear relationships were calculated by cross-correlation analysis and is and estimation of beta-cell responsiveness (pmol/kg/min)/mmol/l [ Time Frame: 180 minutes ] [ Designated as safety issue: No ]
