What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

This trial targets 100 participants in total. It began in 2026-06 with a primary completion date of 2027-03.

Brief Summary

7-Ketolithocholic Acid, a naturally occurring bile acid, is a novel food currently under investigation for potential metabolic benefits, including glucose-lowering effects. This study aims to evaluate the efficacy and safety of 7-Ketolithocholic Acid, administered alongside a low-glycaemic, hypocaloric diet, and increased physical activity in reducing fasting plasma glucose and other metabolic parameters in subjects with prediabetes. Demonstrating a clinically meaningful glucose-lowering effect would support its potential role in early intervention to prevent or delay the onset of type 2 diabetes.

Eligibility Criteria

Inclusion Criteria: 1. Male and female participants aged ≥18 years and ≤70 years. 2. Ability and willingness to provide written informed consent. 3. Diagnosis of prediabetes, defined by the following metabolic criteria: * Impaired fasting glucose (IFG): fasting plasma glucose levels between 100 and 125 mg/dL. * Impaired glucose tolerance (IGT): plasma glucose levels between 140 and 199 mg/dL measured 2 hours after a standard oral glucose tolerance test (OGTT). * Elevated HbA1c: HbA1c values between 5.7% and 6.4% (or 42 and 47 mmol/mol). 4. Body mass index (BMI) in the range 25-31 kg/m2 (inclusive). 5. Willingness to strictly comply with a low-glycaemic, hypocaloric diet during the study period and maintain a food diary. 6. Willingness to comply with recommended physical activity during the study period and maintain an activity diary. 7. Women of childbearing potential must agree to not become pregnant during the study and to use effective contraception (according to Recommendations related to contraception and pregnancy testing in clinical trials. Exclusion Criteria: 1. Previous or current diagnosis of diabetes mellitus. 2. Presence of hypertension, defined as blood pressure \>130/85 mmHg. 3. Hypertriglyceridemia, defined as fasting blood triglyceride levels ≥ 200 mg/dL. 4. LDL cholesterol ≥ 190 mg/dL. 5. Current treatment with oral hypoglycaemic agents or use of supplements with hypoglycaemic effects. 6. Use of any medication (self-medication or prescription medication) or supplementation potentially acting on glucose and lipid parameters within 28 days before entry in the study (or at least 5 times the respective elimination half-life, whichever is longer). 7. Any medical condition or treatment that, in the opinion of the investigator, could interfere with the study outcomes or participant safety. 8. Use of vitamin K antagonist anticoagulant drugs (such as warfarin). 9. Pregnancy or breast-feeding. 10. Any other condition that would preclude adherence to the study protocol or informed consent process, including, but not limited, to active or uncontrolled metabolic, endocrine, cardiovascular, renal, hepatic, pulmonary, gastrointestinal, neurological, endocrinological, immunological, or psychiatric disease. 11. Subjects with any history of hypersensitivity to the product under study or its excipients (please refer to Appendix B for listing of ingredients).
