Prospective Evaluation of the Radiographic Efficacy of Enbrel

Completed
Conditions
Rheumatoid Arthritis
Psoriasis Arthritis
Interventions
Registration Number
NCT01623752
Lead Sponsor
Pfizer
Brief Summary

It is known from the COMET-trial that patients who start Enbrel treatment early have a great chance of reaching clinical remission and radiographic nonprogression. It is still unclear, however, how many patients with early arthritis achieve remission and radiographic nonprogression under the conditions of routine rheumatologic care and the local recommendations of Enbrel treatment (pre-treatment of at least 2 DMARDs, one of them MTX).

Therefore, no robust x-ray data are available to show/demonstrate

* the average extent of x-ray damage in routine patients on Enbrel outside clinical studies.

* if the outstanding effect on structural damage of Enbrel can be reproduced in routine practice.

* that the 'Silent Progressor' is an issue relevant not only in clinical trials, but also for day-to-day decision making.

* the optimal onset of Enbrel treatment in the course of the disease to prevent radiographic damage

Linear Relationship Between Normalized Radiographic Progression and Disease DurationBaseline up to Week 78

Linear relationship between radiographic progression and disease duration was evaluated using a linear regression model. Dependent variable was normalized progression under treatment with Etanercept and independent variable was disease duration.

Effect on Normalized Radiographic Progression With Respect to Baseline Positivity of Anti-citrullinated Protein Antibody (ACPA) - Rheumatoid Factor (RF)Baseline up to Week 78

Effect on normalized radiographic progression with respect to ACPA-RF was evaluated using an analysis of variance (ANOVA) model. Dependent variable was normalized progression under treatment with Etanercept and independent variable was groups of positive testing of ACPA and RF at baseline.

Effect on radiographic progression with respect to baseline DAS-28 was evaluated using ANOVA model. Dependent variable was normalized progression under treatment with Etanercept and independent variable was baseline DAS-28. Baseline DAS-28 is less than or equal to (\<=) 5.1 or \>5.1. DAS28: score range from 0 (none) to 9.4 (extreme disease activity); low =2.6 to 3.2, moderate =3.2 to 5.1, and high disease activity \>5.1. DAS28 score of \<2.6 indicates disease remission.

Each question was answered by the participant as "Yes, I can perform the activity without difficulty" (score assigned =2), "Yes, but with difficulties" (score assigned =1) and "No or only with external help" (score assigned =0). Final FFbH score (%) was then computed according to formula: (Sum of scores\*100) divided by (2\*number of valid answers), ranging between 0 (no functional capacity) to 100 (full functional capacity); higher scores indicate better daily activities. FFbH functional remission was defined as FFbH functional capacity of \>= 83%.
