Investigating the effects of GIP and GLP-1 hormones on insulin secretion and metabolism

Separate and Combined Extrapancreatic Effects of Glucose-dependent Insulinotropic Polypeptide (GIP) and Glucagon-Like Peptide 1 (GLP-1)

Not applicable Interventional University Hospital, Gentofte, Copenhagen · NCT06895408

This study is testing how two gut hormones, GIP and GLP-1, affect insulin production and metabolism in people who have had their pancreas removed, to see if they can help improve treatments for diabetes and obesity.

What this trial studies

This study examines the separate and combined effects of two gut hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1), on insulin secretion and metabolic processes in patients who have undergone total pancreatectomy. The research aims to understand the extrapancreatic effects of these hormones, particularly focusing on GIP, which has been less studied compared to GLP-1. Participants will receive intravenous infusions of these hormones to evaluate their mechanisms of action, especially in light of a new combined GIP-GLP-1 receptor agonist currently in development. The findings could provide insights into better treatment options for conditions like type 2 diabetes and obesity.

Who should consider this trial

Good fit: Ideal candidates for this study are Caucasian individuals aged 30-75 who have undergone total pancreatectomy and have specific blood hemoglobin levels.

Not a fit: Patients who have had a pancreatectomy within the last 3 months or those with significant comorbidities such as renal impairment or severe heart disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with type 2 diabetes and obesity by elucidating the mechanisms of action of a new class of drugs.

How similar studies have performed: While GLP-1 receptor agonists have been successful in treating diabetes, the specific combined approach of GIP and GLP-1 is relatively novel and has not been extensively tested in prior studies.
