This study has been completed.
Information provided by:
University of Aarhus Identifier:
First received: August 6, 2007
Last updated: September 8, 2009

Ghrelin administration increases appetite and, in rodents, induces weight gain. The aim of this study is to investigate the effect of short term ghrelin administration to humans on metabolism.

Condition Intervention Phase
Healthy Subjects Drug: Ghrelin and saline (as placebo) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Participant)

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Insulin sensitivity [ Time Frame: End of clamp period ]

Secondary Outcome Measures:
  • Effects on lipolysis [ Time Frame: End of basal and end og clamp period ]

Enrollment: 8
Study Start Date: January 2003
Study Completion Date: October 2003
Primary Completion Date: October 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: 2 Drug: Ghrelin and saline (as placebo)
Intravenous infusion

Detailed Description:
The current study is initiated in order to assess the impact of acute ghrelin administration on insulin resistance measured by a hyperinsulinemic euglycemic clamp. Second, as free fatty acid is the predominant substrate during fasting, we aim to asses the effects of ghrelin on local and systemic lipolysis.
