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.

Leflunomide naïve patients or patients with previous Leflunomide administration (after at least 6 month wash out period from date of baseline visit) who will be prescribed Leflunomide at the sole decision of the treating physician. 4. Patients with or without another DMARDs including Methotrexate, Sulfasalazine and/or Hydroxychloroquine with or without steroids use who experienced therapy resistance, inadequate response or intolerance. 5. Patients read, understand and signed informed consent prior to inclusion. 6. Patients willing to complete and literate in the language of the available Health Assessment Questionnaire (HAQ Disability Index) either alone or with minimal assistance from caregivers and/or trained site personnel.

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. | 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. |

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.
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.
