Trial Outcomes & Findings for Study Evaluating Etanercept and Sulphasalazine in Ankylosing Spondylitis (NCT NCT00247962)

NCT ID: NCT00247962

Last Updated: 2012-11-08

Results Overview

ASAS measures symptomatic improvement in Ankylosing Spondylitis (AS) participants ASAS = 4 domains: participant global assessment of disease activity, pain, function, inflammation. ASAS 20 = 20% improvement from baseline and an improvement ≥ 10 units on a 0-100 scale (0=no disease activity; 100=high disease activity) for ≥ 3 domains, and no worsening in remaining domain.

PRIMARY outcome

Timeframe: 16 weeks

Population: All randomized patients who received at least 1 dose of study drug and had at least 1 post-baseline efficacy evaluation. Last observation carried forward approach (LOCF) used for missing data imputations.

ASAS measures symptomatic improvement in Ankylosing Spondylitis (AS) participants ASAS = 4 domains: participant global assessment of disease activity, pain, function, inflammation. ASAS 20 = 20% improvement from baseline and an improvement ≥ 10 units on a 0-100 scale (0=no disease activity; 100=high disease activity) for ≥ 3 domains, and no worsening in remaining domain.

SECONDARY outcome

Timeframe: Baseline and 16 Weeks

Population: The analysis population was limited to subjects whose native language was English, Hungarian and Dutch.

ASQoL is a questionnaire to assess disease specific quality of life. It consists of 18 statements that are relevant to the physical and mental conditions for a patient with Ankylosing Spondylitis (AS). Each statement is answered by the patients as a "Yes" (scored as 1) or "No" (scored as 0). All item scores are summed to give a total score. Scores can range from 0 (good QoL) to 18 (poor QoL).
