Trial Outcomes & Findings for Study Evaluating Etanercept for the Treatment of Refractory Heel Enthesitis in Spondylarthropathy (NCT NCT00420303)

NCT ID: NCT00420303

Last Updated: 2010-07-20

Results Overview

PGA was measured using a 100mm Visual Analog Scale (VAS) ranging from 0=very good to 100=very bad. The normalized net incremental area under the curve of the PGA is the area between the baseline and the PGA curve as a function of time (week 2, 4, 8, 12). AUC was computed using the linear trapezoidal method. All the areas above the baseline and under the curve are positive and all the area below the baseline and above the curve are negative. The net incremental AUC is the sum of these areas. This result is then divided by the study duration of the patients. (negative value = improvement).

PRIMARY outcome

Timeframe: 12 weeks

Population: All randomized patients who received at least 1 dose of test article. Last observation carried forward (LOCF)

PGA was measured using a 100mm Visual Analog Scale (VAS) ranging from 0=very good to 100=very bad. The normalized net incremental area under the curve of the PGA is the area between the baseline and the PGA curve as a function of time (week 2, 4, 8, 12). AUC was computed using the linear trapezoidal method. All the areas above the baseline and under the curve are positive and all the area below the baseline and above the curve are negative. The net incremental AUC is the sum of these areas. This result is then divided by the study duration of the patients. (negative value = improvement).

PRIMARY outcome

Timeframe: Baseline and 12 weeks

Population: All randomized patients who received at least 1 dose of test article.

The patient global assessment of disease activity was measured using a 100mm Visual Analog Scale (VAS) ranging from 0=very good to 100=very bad. Change=12 week score minus baseline score. A negative score indicates an improvement in disease activity and a positive score indicates worsening.

SECONDARY outcome

Timeframe: 12 weeks

Population: All randomized patients who received at least 1 dose of test article.

A response is defined as at least a 50% improvement (decrease) from baseline in the patient global assessment of disease activity. The patient global assessment of disease activity was measured using a 100mm Visual Analog Scale (VAS) ranging from 0=very good to 100=very bad.
