Scientists probe fat and blood molecules to unlock new diabetes treatments
NCT ID NCT06955130
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study investigates how two molecules—glycerol from fat and lactate from the blood—are converted into glucose by the liver, especially in people with type 2 diabetes. Researchers will compare these processes in 48 adults with and without diabetes or obesity. Participants receive infusions of glycerol, lactate, and glucose along with glucagon, and blood samples are analyzed to track carbon flow. The goal is to identify new drug targets for lowering blood glucose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Glycerol, Lactate, Glucose
- What this could lead to
- If successful, this research could point toward new drug targets that lower blood glucose more effectively in type 2 diabetes.
- What could go wrong
- This is an early-stage observational study with only 48 participants. It measures metabolic processes, not treatment outcomes, so direct benefits are uncertain.

Inclusion Criteria for All Subjects 1. Age 40-70 years. 2. The subject is otherwise in general good health, based on medical history and physical examination. Inclusion Criteria for Metabolically Healthy Subjects without Obesity 1. No evidence of T2D or prediabetes as indicated by the American Diabetes Association (ADA), i.e., HbA1c \< 5.7%, fasting glucose \< 100 mg/dL, or use of glucose-lowering medications. 2. Body mass index (BMI) ≤ 24.9 kg/m2. Inclusion Criteria for Metabolically Healthy Subjects with Obesity 1. No evidence of T2D or prediabetes as per ADA criteria. 2. 30.0 ≤ BMI ≤ 45.0 kg/m2. Inclusion Criteria for T2D Subjects 1. Evidence of T2D as indicated by ADA criteria. 2. 6.5% ≤ HbA1c ≤ 8.0%. 3. 30.0 ≤ BMI ≤ 45.0 kg/m2. Exclusion Criteria for All Subjects 1. Chronic medical conditions that may affect glucose metabolism, including active malignancy, tobacco use, HIV infection, kidney failure, liver dysfunction, alcoholism, pancreatitis, active viral/bacterial infection, current pregnancy/lactation, anemia, severe cardiac or respiratory failure, and uncontrolled hyperlipidemia (total cholesterol ≥ 260 mg/dL or triglycerides ≥400 mg/dL). 2. Current medical therapy that affects glucose metabolism such as glucocorticoid, antipsychotic, or oral contraceptive pills. 3. Type 1 diabetes mellitus diagnosis and/or history of diabetic ketoacidosis. 4. Use of weekly glucagon-like peptide-1 (GLP-1) receptor agonist therapy.
