Secretin injection effects on pancreatic fluid in healthy adults

An Open-Label Study On The Effects Of Human Secretin For Injection (CHIROSTIM) On Pancreatic Fluid Composition In Normal Human Volunteer Participants

Phase 4 Interventional Mayo Clinic · NCT07285863

This test gives a synthetic secretin injection (ChiRhoClin) to healthy adults undergoing endoscopic ultrasound to see if it changes what’s in pancreatic fluid.

What this trial studies

Healthy adults undergoing an endoscopic ultrasound for a non-pancreatic reason receive an injection of human synthetic secretin (ChiRhoClin). Pancreatic fluid is collected from the duodenum using an endoscopic pancreas function collection method after secretin stimulation. Samples will be analyzed to characterize changes in pancreatic fluid composition following stimulation. Participants are screened to exclude anyone with pancreatic disease, altered upper GI anatomy, liver disease, pregnancy or regular tobacco/alcohol/anticholinergic use.

Who should consider this trial

Good fit: Ideal candidates are healthy men or non-pregnant women age 18–80 who are scheduled for an endoscopic ultrasound for a non-pancreatic indication, are ASA class 3 or below, and meet the trial's exclusion criteria (non-smokers, limited alcohol, no pancreatic or major GI surgery, no liver disease).

Not a fit: Patients with a history of pancreatitis or other pancreatic disease, inflammatory bowel disease, prior vagotomy or altered upper GI anatomy, liver disease, pregnancy or nursing, regular anticholinergic use, smoking, or heavy alcohol use are excluded and unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could improve understanding of pancreatic secretions and help refine diagnostic tests for pancreatic exocrine function.

How similar studies have performed: Secretin-stimulated pancreatic secretion testing and duodenal fluid collection are established techniques used in clinical and research settings, so the approach is not novel but aims to add specific compositional data.
