Clinical trials: Endogenous Hyperinsulinism
Insulin Resistance
Regulation of Endogenous Glucose Production by Brain Insulin Action in Insulin Resistance
It is well known that the hormone insulin lowers blood glucose in part by acting directly on the liver and reducing hepatic glucose production.

Autonomic Function
Understanding Individual Variability in Neuronal Signal Transmission to Target Organs in Health and Disease
The goal of this clinical trial is to evaluate the influence of parasympathetic transmission from the brain to different metabolic organs. This transmission can be blocked with the muscarinic antagonist atropine.
- Trial name
- CPB_Atropine (NCT06912048)
- Testing
- Oral glucose tolerance test with double-tracer dilution and atropine infusion
- Where
- Germany
- Volunteers
- 52 people, healthy volunteers welcome

Depression, Insulin Resistance
Endogenous Opioid Activity and Affective State in Insulin Resistant Women
Insulin resistance, a primary component of the metabolic syndrome, is an escalating phenomenon in the United States, and confers an increased risk of depression and mood disorder, particularly in women.

- Trial name
- NCT02069379
- Testing
- Metformin
- Where
- United States
- Volunteers

Hypertension, Obesity
Microvascular Dilatation After Endogenous Induced Hyperinsulinemia
In this study we will examine if the insulin-induced microvascular effects will occur after a physiological stimulus (i.e. a oral glucose tolerance test).

Glucose Metabolism Disorders
Relative Contribution of Brain Insulin Action for Postprandial Metabolism
The goal of this clinical trial is to clarify (i) the contribution of brain insulin action on regulation of systemic metabolism, (ii) sex-specific differences in the central regulation and (iii) the influence of the menstrual…
