About this trial

This is an interventional basic science trial for Diabetes Mellitus, Type 2

Eligibility Criteria

50 Years - 70 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Have a body mass index (BMI) between 25 to 40 kilograms per meter squared (kg/m²),
  • For participants with a confirmed type 2 diabetes diagnosis: The condition must be managed either by diet and exercise alone or on a stable dose of metformin
  • For nondiabetic subjects: participants must agree to keep their diet and physical activity habits stable throughout the study
  • Female participants must be post-menopausal and male participants

Exclusion Criteria:

  • Poorly controlled diabetes
  • Unstable body weight within 30 days prior to screening.
  • For non-diabetic control subjects: evidence of diabetes or prediabetes at screening.
  • Having worked as a metal worker or welder
  • History of alcohol or drug abuse within 5 years of the screening
  • Currently participating, or previous participation in another clinical trial within 30 days prior to the screening visit, or previous participation in another PET imaging study within 12 months.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Experimental: Imaging Biomarkers

Arm Description

Each study subject is is studied in four session: twice after overnight fast and twice after liquid meal injestion using PETMRI imaging. Adipose and skeletal muscle pefusion and fatty adic uptake are measured and and the repeability of results tested for these two situations. In PEt studies PET/MRI Scan with radioactive water ([15O]-H2O) and [18F]-FTHA are used as tracers. In this experimental study number of subjects studied is rather small. Therefore volunteers with and without T2 diabetes are analysed together and not on different arms.

Outcomes

Primary Outcome Measures

To evaluate the repeatability of the ratio of subcutaneous adipose tissue (SAT) to skeletal muscle fatty acid uptake rates
The ratio of SAT to skeletal muscle fatty acid uptake rates

5. Study Description

Brief Summary
The main purpose of this study is to evaluate the overall variation in the assessment of fatty acid uptake and blood flow in adipose tissue and skeletal muscle in the fasted and postprandial states by evaluating the repeatability of whole-body three-dimensional kinetic (4D) combined positron emission tomography and magnetic resonance imaging (PET/MRI) readouts in participants with type 2 diabetes mellitus (T2DM), and non-diabetic control participants. Each volunteer participates 4 scanning sessions.
Detailed Description
A total of approximately 13 T2DM and 6 control subjects (a total of 19 subjects) are planned to be enrolled to achieve 11 T2DM and 5 control subjects to complete the study, assuming a 15% drop-out rate. The test-retest repeatability of the ratio of FTHA uptake rates in subcutaneous adipose tissue (SAT) to skeletal muscle is measured using the intra-class correlation coefficient (ICC). Assuming an ICC of 0.85, with a 5% two-sided type I error rate, a sample size of 16 completers will yield approximately 90% power to detect an ICC statistically significantly greater than 0.4 (usually considered as a criterion for moderate agreement). The total radiaooin burden for tshi sitdu yis 27.4 mSv. The study is approved by the local Ethical committtee and Fimea.

Single Group Assignment
Masking
None (Open Label)
Masking Description
One arm: Subjects are studied under two consecutive conditions, after overnight fasting and after a liquid meal ingestion. During each condition they are examined for fatty acid uptake in subcutaneous fat and skeletal muscle by FTHA([18F]-FTHA) PET/MRI as well as adipose and skeletal muscle blood perfusion by radioactive water([15O]-H2O ) PET/MRI. This was done at two occasions, 2-14 days apart, to assess repeatability of the measurements. Assigned interventions: [18F]-FTHA tracer injections [15O]-H2O tracer injections PET/MRI imaging Overnight fasting Liquid meal ingestion
