Bile Acids and Incretins in Pancreas Kidney Transplant Patients (ITABI)

December 13, 2025 updated by: Hospices Civils de Lyon

Impact of Duodena-pancreatic Transplantation on Bile Acids and Incretins Metabolism.

Pancreas Kidney Transplantation (PKT) is the prominent treatment for type 1 diabetic patients with chronic kidney disease and improves patients' outcome. However, in spite of an optimized systemic insulin substitution, altered glucose metabolism and beta cell function are reported in these patients. The mechanisms behind these abnormalities are still unclear. Duodena-pancreatic anastomosis is performed in a heterotopic site (ileum) and thus could change physical and chemical properties of intestinal secretions, gut flora, as well as intestinal permeability. The effect of this procedure on gut derived metabolic factors, the enterohepatic cycle of bile acids, incretin secretion and intestinal flora have never been studied. This pilot prospective, study is aimed to evaluate the modification of bile acids concentrations and composition in PKT subjects, and the impact in glucose and incretin metabolism (measured by oral glucose tolerance test) one year after transplantation. The results will be compared to those of kidney transplant patients and control subjects.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
50

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Bile acids concentrations
Time Frame: One year after transplantation
Plasmatic bile acids concentration will be measured in serum by biochemical analysis
One year after transplantation
Bile acids composition
Time Frame: One year after transplantation
Plasmatic bile acids composition will be assessed in serum by gas chromatography
One year after transplantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Relationship between bile acid modifications and Oral Glucose Tolerance test (OGT) measures
Time Frame: One year after transplantation
OGT will be performed in all subjects. Data on insulin sensitivity and secretion, Glucagon-Like Peptide 1 (GLP-1) and fibroblast growth factor-19 will be collected
One year after transplantation
Impact of Pancreas-Kidney Transplantation (PKT) on LipoPolySaccharides (LPS)
Time Frame: One year after transplantation
LPS level will be measured before transplantation and one year after transplantation
One year after transplantation
Impact of PKT on intestinal flora
Time Frame: One year
Gut microbiota will be analysed before and after transplantation
One year
