Current Primary Outcome Measures
 (submitted: June 14, 2020)
  • 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
  • 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.
Original Primary Outcome Measures
 (submitted: July 24, 2018)
  • The mean relative change in clinical disease activity index (CDAI) among patients with active rheumatoid arthritis treated with leflunomide throughout study duration. [ 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 changes in CDAI score). 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
  • The mean relative change in health assessment questionnaire - disability index score (HAQ DI) among patients with active rheumatoid arthritis treated with leflunomide throughout study duration. [ 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 changes in HAQ-DI score). There are eight categories; first score within each category:
    • Dressing and Grooming
    • Arising
    • Eating
    • Walking
    • Hygiene
    • Reach
    • Grip
    • Activities The score for the disability index is the mean of the eight category scores. The higher score indicates greater disability.

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.
