Response to Semaglutide in Non-diabetic Obese Patients With Varying Degrees of Insulin Resistance
Treatment Response to Incretin Mimetics in Non-diabetic Obese Patients With and Without Insulin Resistance (TRIM-IR)

Rövid összefoglaló (regiszter, angolul)
Incretin mimetics are widely used pharmacological treatments for weight loss, known for their high efficacy and favorable safety profile. As the most commonly prescribed drug in this class, semaglutide is effective in both diabetic and non-diabetic individuals. However, treatment responses vary significantly, with non-diabetic individuals typically experiencing better weight loss outcomes. Despite this, up to 10% of non-diabetic individuals show little or no response to treatment, and the reasons for this variability remain unclear. The TRIM-IR study aims to investigate the role of insulin resistance (IR) in weight loss outcomes among non-diabetic obese individuals receiving semaglutide. This single-center, observational study will assess the impact of IR on weight loss, body composition, and adipose tissue function during the first 16 weeks of semaglutide therapy. The study will also explore molecular markers of adipose tissue dysfunction, focusing on the transition from dysfunctional to healthy adipose tissue. The investigators hypothesize, that individuals with lower IR will experience greater weight loss than those with higher IR, and that the glucose infusion rate (GIR) during hyperinsulinemic euglycemic clamp testing will correlate with weight loss variability. Secondary objectives include comparing changes in fat and lean mass, reductions in visceral fat, and improvements in adipose tissue function before and after 16 weeks of treatment. Exploratory analyses will assess adipocyte subpopulations and their response to insulin sensitivity changes. A total of 40 participants, equally distributed by gender, will be enrolled to ensure statistical power for detecting clinically relevant differences. The study aims to optimize semaglutide use for personalized obesity treatment and provide insights into the relationship between obesity, insulin resistance, and adipose tissue plasticity, with implications for improving obesity management and cardiovascular health outcomes.

Ki nem vehet részt
Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.
Korábbi kezelés
- Medication and/or pathologies that prevent the safe execution of the fat tissue biopsies (e.g. allergy towards local anesthetics, disorders of coagulation, treatment with anticoagulants)
- Treatment with a GLP-1 (glucagon like peptide 1) receptor agonist within 180 days before screening
- A self-reported change in body weight >5% within 90 days before screening
- Treatment with any medication for the indication of obesity within the past 90 days before screening
Más betegség
- Pregnancy or active breast feeding
- Therapy with semaglutide is not approved for use during pregnancy or while breastfeeding, as its safety and efficacy in these conditions have not been established.
- Pregnancy is an exclusion criterion for the planned investigations to avoid placing pregnant individuals under unnecessary physical or psychological stress that could pose risks to both the individual and the fetus.
- Medical conditions that prevent examinations and testing (e.g. epilepsia, symptomatic cardiovascular disease)
- History of or planned bariatric surgery
- History of type 1 or type 2 diabetes mellitus
- Active malignancy (<2a since remission)
Laborértékek
- HbA1c ≥ 6.5% as measured by the central laboratory at screening
- Fasting plasma-glucose >7.0 mmol/l
- Treatment with glucose-lowering agent(s) (e.g. Metformin) within 90 days before screening
- Uncontrolled thyroid disease, defined as thyroid stimulating hormone (TSH) > 10 mIU/L or < 0.4 mIU/L as measured by the central laboratory at screening
