| Main Objective: The objectives of this study are to assess the efficacy of CRx-102 in subjects with active RA using ACR 20 and to assess the safety and tolerability of CRx-102.;Secondary Objective: NA;Primary end point(s): Primary Endpoint: To assess the superiority of CRx-102 (2.7 mg/360 mg) compared to prednisolone (2.7 mg) and dipyridamole (360 mg) using ACR 20 calculated from Baseline to Day 98 in subjects with active RA Secondary endpoints: To assess the efficacy of CRx-102 (2.7 mg/180 mg) compared to prednisolone (2.7 mg) and dipyridamole (360 mg) using ACR 20 calculated from Baseline to Day 98 To assess the efficacy of each dosage of CRx-102 to placebo using ACR 20 calculated from Baseline to Day 98 Exploratrory endpoints: To assess the efficacy of each dosage of CRx-102 compared to prednisolone (2.7 mg), dipyridamole (360 mg), and placebo using DAS 28 To assess the efficacy of each dosage of CRx-102 compared to prednisolone (2.7 mg), dipyridamole (360 mg), and placebo in lowering CRP levels Hand x-ray analysis will be performed to assess potential disease modifying activity including joint space narrowing, erosions and total Sharp score. | — |
