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)

Condition or disease
Active Rheumatoid Arthritis

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.

Primary Outcome Measures :
  1. Number of Patients With Remission, Low, Moderate or High Disease Activity (in Terms of CDAI Scores) in Visits 1 and 6. [ Time Frame: 9 months ]

    Assessing the clinical efficacy of leflunomide as first-line therapy and as add-on therapy to other DMARDs, with or without steroids in Egyptian patients with active rheumatoid arthritis [in terms of the number of patients in remission (i.e. CDAI score 0.0 - 2.8), of low disease activity (i.e. CDAI score 2.9 - 10.0), of moderate disease activity (i.e. CDAI score 10.1 - 22.0) and of high disease activity (i.e. CDAI score 22.1 - 76.0) in visits 1 (at baseline) and 6 (at week 36)].

    CDAI score: The sum of Tender joint score, Swollen joint score, Patient global score, and Patient global score.

    CDAI score interpretation:

    0.0 - 2.8: Remission 2.9 - 10.0: Low Activity 10.1 - 22.0: Moderate Activity 22.1 - 76.0: High Activity


  2. Number of Patients With Different Disability Scores in Terms of the Mean Relative Change in Health Assessment Questionnaire - Disability Index Score on Visits 1 and 6. [ Time Frame: 9 months ]

    Assessing the clinical efficacy of leflunomide as first-line therapy and as add-on therapy to other DMARDs, with or without steroids in Egyptian patients with active rheumatoid arthritis [in terms of the number of patients with mild difficulties to moderate disability, moderate to severe disability and severe to very severe disability; according to the mean relative change in health assessment questionnaire - disability index score (HAQ-DI) at visits 1 (at baseline) and 6 (at week 36)].

    A HAQ-DI score of 0.0 - 1 indicates mild difficulties to moderate disability, a HAQ-DI score of 1.1 - 2 indicates moderate to severe disability and a HAQ-DI score of 2.1 - 3 indicates severe to very severe disability.

    There are eight categories; first score within each category: Dressing and Grooming, Arising, Eating, Walking, Hygiene, Reach, Grip, and Activities.

    Total score is the mean of the eight category scores. Higher scores indicate greater disability.



Secondary Outcome Measures :
  1. Number of Adverse Events (AEs)/ Serious Adverse Events (SAEs) Experienced by Rheumatoid Arthritis Patients Receiving Leflunomide as First-line Therapy and as add-on Therapy to Other DMARD, With or Without Steroids and Their Relation to Study Medication. [ Time Frame: 9 months ]
    Identifying the safety profile of leflunomide whether used as first-line therapy and/or as add-on therapy to other DMARDs with or without steroids in Egyptian patients with active rheumatoid arthritis.
