Brief summary: A Phase IV, Multi-Centric, Prospective, Observational Study to Assess the Clinical Efficacy and Safety of Leflunomide in Egyptian Patients with Active Rheumatoid Arthritis. (CLEAR)

Detailed description: CLEAR is a phase IV, multi-centric, prospective, observational study to assess the clinical efficacy and safety of Leflunomide as first-line therapy and as add-on therapy to other DMARDs (such as Methotrexate, Hydroxychloroquine, Sulfasalazine) with or without Steroids use in Egyptian patients with Active Rheumatoid Arthritis.
