Metformin and Dietary Restriction to Prevent Age-related Morbid Events in People With Metabolic Syndrome

• Status: Completed
• Trial end date: 2019-07-01
• Target enrollment: 0
• Participant gender: All

Summary

Phase III randomized controlled trial on men and women with Metabolic syndrome (MetS) to test the hypothesis that comprehensive life-style changes and/or metformin treatment prevent age-related chronic non-communicable diseases (ArCD).

The aim of the present study is to evaluate the effect of a comprehensive life-style intervention (including moderate physical activity and Mediterranean/macrobiotic diet with moderate calorie and protein restriction), and of treatment with Metformin (a calorie restriction mimetic drug) for the prevention of ArCD.

• Phase: Phase 3

Criteria

Inclusion Criteria:

• Age 55-74, waist circumference equal or greater than 85 cm for women and 100 cm for men, plus at least two other factors among those defining the MetS

Exclusion Criteria:

• Diagnosed diabetes (or baseline fasting glycemia above 7mmol/L at baseline examination)

• Cancer (except skin carcinoma) diagnosed in the last 5 years, or under treatment

• Excessive frailty: in absence of agreed-upon measurements parameters and cutoff points, the investigator will exclude subjects under the lower 5th percentile of the muscular mass distribution estimated by impedance in previous studies

• Conditions that contraindicate the use of MET because might favour lactic acidosis:

• Renal, cardiac, hepatic, or respiratory insufficiency

• Serum creatinine <124μmol/L, or proteinuria at baseline examination

• Current treatment with K-sparing diuretics, or with proton pump inhibitors

• Excessive alcohol consumption

• Distressing side effects of MET treatment. Nausea and diarrhoea typically occur in about one third of patients receiving MET for the first time at full dose. To avoid dropouts for gastrointestinal discomfort we will treat all volunteers with half the planned dose for one month in order to exclude intolerant subjects before randomization. Participants randomized in the intervention group will continue to take half a dose for one month and then shift to the full dose.
