September 29, 2021 updated by: Pfizer

Clinical Outcomes of Early Versus Delayed Management of Iraqi Patients With Ankylosing Spondylitis (AS) With Etanercept

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Baseline, Month 12 [from the data retrieved and observed in 2 months of this study]
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.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2020

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
