Study To Evaluate The Impact Of Early Initiation Of Biological Treatment With Ankylosing Spondylitis

Overview

This study is to evaluate available data in Iraqi patients with ankylosing spondylitis on Enbrel treatment with regards to the impact of early treatment using data from the Baghdad Teaching Hospital registry

Full Title of Study: “Clinical Outcomes of Early Versus Delayed Management of Iraqi Patients With Ankylosing Spondylitis (AS) With Etanercept”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: October 1, 2020

Interventions

  • Drug: Etanercept
    • Patients with ankylosing spondylitis as provided in real world practice

Arms, Groups and Cohorts

  • Patients with ankylosing spondylitis
    • Iraqi patients diagnosed with ankylosing spondylitis that received Etanercept as treatment for disease

Clinical Trial Outcome Measures

Primary Measures

  • Change From Baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) Total Score at Month 12
    • Time Frame: Baseline, Month 12 [from the data retrieved and observed in 2 months of this study]
    • BASFI is a set of 10 questions to determine degree of functional limitation in participants with AS. Participants answered each 10 questions on a scale of 0 (no functional impairment) to 10 (maximal impairment). BASFI total score was calculated as mean of scores from 10 questions. BASFI total score ranged from 0 (no functional impairment) to 10 (maximal impairment), where higher scores meant worse condition. In this outcome measure, participants were grouped on the basis of early and delayed referral to management of AS with etanercept treatment. Early referral was considered when participants were referred to management of AS in less than or equal to (<=) 1 year after diagnosis with AS. Participants with delayed referral to management of AS were divided into 3 groups: 1.1 to 5 years, 5.1 to 10 years and greater than (>) 10 years after diagnosis with AS.
  • Change From Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score at Month 12
    • Time Frame: Baseline, Month 12 [from the data retrieved and observed in 2 months of this study]
    • BASDAI is a set of 6 questions to determine disease activity in participant with AS. Participants answered each 6 questions on a scale of 0 (no problem) to 10 (the worst problem). The BASDAI score is calculated by computing the mean of questions 5 and 6 and adding it to the sum of questions (Q) 1-4. This score is then divided by 5. BASDAI score = (Q1 + Q2 + Q3+ Q4+ [Q5 + Q6/2])/5. BASDAI score ranges from 0 (best) to 10 (worst), where higher scores meant worse condition. In this outcome measure, participants were grouped on the basis of early and delayed referral to management of AS with etanercept treatment. Early referral was considered when participants were referred to management of AS in <= 1 year after diagnosis with AS. Participants with delayed referral to management of AS were divided into 3 groups: 1.1 to 5 years, 5.1 to 10 years and >10 years after diagnosis with AS.
