Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Weight (Value in kg). Measurement time: At baseline, 3, 6, 9 and, 12 months. Waist circumference (value in cm). Measurement time: At baseline, 3, 6, 9 and, 12 months.

Key secondary outcomes:

Efficacy outcomes: 1. Measurements and anthropometric indexes. Measurement time: at baseline, 3, 6 and, 12 months. It will measure by: -Body Max Index-BMI (Weight/(Height*Height). The weight expressed in Kg and, the height expressed in meters) - Hip circumference (Value expressed in cm) - Waist-hip Index (Waist circumference/Hip circumference. All values are expressed in cm) - Waist- Height Index (Waist circumference/Height. All values are expressed in cm - Conicity Index (Waist circumference in cm/(0.109*square root of (weight in kg/height in cm))) 2. Glucose on an empty stomach and at two hours after an oral glucose tolerance test (Value expressed in mmol/L). Measurement time: at baseline, 6 and, 12 months. 3. Hemoglobin (Value expressed in g/L). Measurement time: at baseline, 6 and, 12 months. 4. Hemoglobina glucosilada -HbA1c (Value expressed in %). Measurement time: at baseline, 6 and, 12 months. 5. Fasting insulin (Value expressed in μU/ml). Measurement time: at baseline, 6 and, 12 months. 6. Insulin resistance indexes. - HOMA-IR will be calculated by the homeostatic model of Mathews - HOMA-β will be determined by the homeostatic model (HOMA) of Mathew - QUICKI Index calculated as [1/[log insulin0 + log glucose0] - Bennett Index calculated as [40/insulin0] - Raynaud Index calculated as 1/(log insulin0 x log glucose0) 7. Biochemistry test (Triglycerides, Cholesterol, HDL-c, LDL-c, TGP; TGO, GGT, Uric acid, Creatinine in μmol/L). Measurement time: at baseline, 6 and, 12 months. 8. Blood Pressure (Systolic and Diastolic blood pressure expressed in mmHg).Measurement time: at baseline, 3, 6, 9 and, 12 months. Safety outcomes: 9. Adverse Events-AE. Measurement time: at baseline, 1 ½ month (6 weeks), 3 months, 4 ½ months (20 weeks), 6 months, 9 months and, 12 months. - Occurrence of some AE in the subject (Yes, No). -Type of AE (description of EA using the Common Terminology Criteria for Adverse Events (CTCAE), version 4.0) - Intensity of the AE (Light, Moderate, Severe according to 45/2007 CECMED regulation) - Seriousness of the AE (Serious, Not serious) - Duration of the AE (Time from event start until stop the event) - Attitude regarding the treatment under study (No changes, Dose modification, Treatment temporary interruption, Treatment definitive interruption) - Result of the AE (Recovered, Improved, Persists, Squeals) - Causality relationship (Very likely, Probable, Possible, Unlikely, Not related, Not evaluable) -Treatment indicated for the AE (Specify the treatment for every AE)
