About this study

Official title: A Phase IV, Multi-Centric, Prospective, Observational Study to Assess the Clinical Efficacy and Safety of Leflunomide in Egyptian Patients With Active Rheumatoid Arthritis

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)

Read the 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.

Conditions: Active Rheumatoid Arthritis
Keywords: RA

What is being measured

The primary outcome is the main question the study is designed to answer.

Number of Patients With Remission, Low, Moderate or High Disease Activity (in Terms of CDAI Scores) in 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 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
Measured: 9 months
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.
Measured: 9 months

Secondary outcomes (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.
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.
Measured: 9 months
