Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
IV GLP-1 (1.2 pmol/kg/min) infusion or placebo will be administrated to participants over 2 visits. Participants will receive a second IV containing either Secretin (75ng/kg/hr) and CCK (20ng/kg/hr) or placebo over 2 visits. Adherence of intervention will be monitored by both the clinical trial pharmacy and the researchers in the study to ensure the participants receive the correct treatment/placebo on any given trial day. Participants will be studied over 4 occasions, separated by at least 4 days.
Intervention code [1] 289798 0
Treatment: Drugs
Comparator / control treatment
On visits when participants aren't receiving GLP-1 or Secretin + CCK they will receive human albumin and saline, respectively.
Control group
Placebo

Outcomes
Primary outcome [1] 292627 0
To determine whether GLP-1 acutely stimulates pancreatic exocrine function in health. This will be assessed by peak duodenal bicarbonate concentration and pancreatic bicarbonate output.

Peak duodenal amylase concentrations and amylase concentration area under the curve.
Timepoint [1] 292627 0
Duodenal Aspirates will be collected every 15 mins for an hour to assess pancreatic function
Secondary outcome [1] 309378 0
Changes in plasma amylase and lipase
Timepoint [1] 309378 0
Bloods will be taken every 15 mins for an hour.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be completed by the clinical trials pharmacy department using a randomisation table created by computer software.
