Efficacy and Safety of Metformin Glycinate Compared to Metformin Hydrochloride on the Progression of Type 2 Diabetes

Study Overview
=================
Brief Summary
-----------------
Phase III study to evaluate the efficacy and safety of the treatment. Two-arm, prospective, longitudinal, double-blind, multicenter randomized clinical trial.

Detailed Description
-----------------
Study to evaluate the efficacy and safety of treatment at 6 and 12 months with metformin glycinate at a dose of 2100 mg / day compared to metformin hydrochloride at a dose of 1700 mg / day on the progression of type 2 diabetes. To assess the change in HbA1c from baseline to 6 and 12 months of treatment (primary endpoint) in both groups. As secondary objectives, changes in fasting glucose levels from baseline, changes in results of the oral glucose tolerance test 2h from baseline, changes in HOMA-IR from baseline, changes in insulin levels, leptin, adipokines and proinflammatory cytokines, MCP-1, nitric oxide and PCr from baseline, changes in BMI from baseline and changes in lipid profile from baseline will be evaluated. A blinded interim analysis will be performed at 6 months of patient follow-up and a final analysis. Demographic data will be analyzed with mean, standard deviation, minimum and maximum. Efficacy analyzes will be carried out in the treated population (all treated patients, ATP), made up of all randomized patients who received at least one dose of the study treatment and who have a baseline measurement and at least one subsequent measurement.
