- Primary Outcome Measures
Name Time Method Main Objective: To assess the clinical efficacy response rate using ACR20 criteria as primary endpoint at 3-month in each initial dosing regimen group of treatment;Secondary Objective:  To assess the clinical efficacy at 1-month and 3-month using complementary efficacy criteria (ACR 50, ACR 70, DAS 28) in each group of treatment. <br> To assess the clinical and biological safety using standard blood monitoring, TEAED and SAE in each group of treatment. <br> To evaluate treatment modifications; particularly leflunomide and concomitant use of AINS and corticoids;;Primary end point(s): The primary end point is the efficacy response rate using ACR 20 criteria al 3-month in each initial dosing regimen group of treatment.
