Phase: Phase 4

Status: Completed

Summary

The purpose of this study objective will be to evaluate the efficacy and safety of etanercept 50 mg BIW in RA subjects who showed a sub-optimal response to standard dose etanercept (50 mg QW) and concomitant methotrexate therapy.

Clinical Details

Official title: A Multi-Center, Randomized, Double-Blind, Active-Controlled Study Evaluating Efficacy and Safety of Etanercept 50 mg Twice Weekly (BIW) in Rheumatoid Arthritis Subjects Who Are Sub-Optimal Responders to Etanercept 50 mg Once Weekly (QW)

Study design: Treatment, Randomized, Double-Blind, Crossover Assignment, Safety/Efficacy Study

Primary outcome: Proportion of subjects achieving a good or moderate DAS28 response (as defined by the EULAR28 response criteria) at Week 12

Secondary outcome:

Proportion of subjects who achieve American College of Rheumatology (ACR) 20, 50, and 70 responses at Weeks 12 and 24

Proportion of subjects achieving a good or moderate DAS28 response (as defined by the EULAR28 response criteria at Week 24 and the proportion achieving clinical remission (DAS28<2.6) at Weeks 12 and 24

Changes from baseline with respect to the DAS28 score and ACR score (including HAQ) criteria at Weeks 12 and 24

Changes from baseline in patient-reported outcomes as measured by the SF-36 at Weeks 12 and 24

Proportion of etanercept 50mg BIW responders at Week 12 who mantain a clinical improvement with etanercept 50mg QW (defined as no DAS28 increase of greater than 0.6 from Week 12) at Week 24

Safety (SAEs and AEs) in three study periods (4-week open label run-in period, 12-week double blinded period A, and 12-week open-label period B)
