Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the efficacy of Methotrexate/Metformin vs. Methotrexate alone on the decrease of RA activity in MTX-naive patients, after 6 months of treatment.;Secondary Objective: - Describe the proportion of patients achieving remission (DAS28 =6.6) at 6, 12 and 24 months in both randomization groups. - Describe the proportion of patients achieving a low level of activity (DAS28 = 3.2) at 6 months in both randomization groups. - Describe the proportion of patients for whom biotherapy is considered at 6, 12 and 24 months in both randomization groups. - Describe the mean dose of Methotrexate prescribed at 6, 12 and 24 months in both randomization groups. - Describe clinical and laboratory parameters related to metabolism in both randomization groups. - Describe the frequency of occurrence of serious adverse events in both randomization groups. - Describe the quality of life of patients in both randomization groups.;Primary end point(s): Level of RA activity according to Disease Activity score on 28 joints (DAS28);Timepoint(s) of evaluation of this end point: After 6 months of treatment | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Proportion of patients who reach remission after 6, 12 and 24 months of treatment (DAS < 2,6) - Proportion of patients with low disease activity after 6 months of treatment (DAS < 3,2) - Proportion of patients for which a biologic treatment is introduced after 6, 12 and 24 months of treatment - Mean dosage of Methotrexate in the two groups of randomization - Description of some metabolic parameters within the two groups of treatment: weight loss, waist circumference, fasting glycemia and hemoglobin A1c level (HbA1c), cholesterol levels, triglycerids, insulinemia, and bilirubin. - Proportion of patients who present a serious adverse event within the two groups during the 6 months of treatment - Description of the evolution of functional assessment according to Health Assessment Questionnaire (HAQ) within the two groups during the 6 months of treatment;Timepoint(s) of evaluation of this end point: After 6 months of treatment | — |
