Clinical Trial Summary

The first 12 weeks of this study will compare the efficacy of etanercept 50 mg once-weekly to placebo in subjects with rheumatoid arthritis who have not responded well to infliximab or adalimumab plus methotrexate. This comparison will be performed for all subjects and separately for subjects who are anti-drug antibody positive for one of these medications. From week 12 to week 24, all subjects will receive etanercept 50 mg once-weekly. The effect of anti-drug antibody status on the efficacy of etanercept as well as the safety profile of etanercept in these subjects will also be evaluated throughout the study.

Description:

This study was prematurely terminated on June 25, 2014 due to significant and continuing delays in achieving the study B1801355 enrolment target. The decision to stop the study was not driven by any safety concerns.

Secondary	Change From Baseline in CRP	The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline in Health Assessment Questionnaire Disability and Discomfort Scales (HAQ-DI)	Health Assessment Questionnaire-Disability Index (HAQ-DI): participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty.	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline in Euro Quality of Life (Qol) EQ-5 Dimensions Questionnaire (EQ-5D)	The EuroQol-5 Dimensions (EQ-5D) is a participant-completed questionnaire designed to assess health related quality of life. There are 2 components to the EQ-5D: a Health State Profile and a VAS. For the Health State Profile, participants recorded their level of current health for 5 domains comprising a health profile: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Scores from the 5 domains may be used to calculate a single index value, also known as a utility score. On the VAS participants were asked to rate their current health on a scale from 0 to 100 mm, where 0 represented the "worst imaginable health state" and 100 represented the "best imaginable health state." In addition to a summary of mean changes, 1 categorical endpoint each based on EQ-5D utility score and 1 based on the VAS were derived and analyzed: EQ-5D utility score improvement =0.05 and EQ-5D VAS score >82.	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline in Short Form-36 Health Survey (SF-36)	The 36-Item Short Form Health Survey (SF-36) is widely used 36-item questionnaire that measures general health-related quality of life in the following 8 domains: physical function, role limitations due to physical health, bodily pain, general health perception, vitality, social functioning, role limitation due to emotional problems, and mental health. Scores for the 8 domains range from 0 to 100 where higher scores are better.	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline in Patient Acceptable Symptom State (PASS)	The Patient Acceptable Symptom State (PASS) was a participant-completed form in which participants were asked to "Think about all the ways your rheumatoid arthritis (RA) has affected you during the last 48 hours. If you were to remain in the next few months as you were during the last 48 hours, would this be acceptable or unacceptable to you?" The participant indicated a response of either "acceptable" or "unacceptable".	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline in Vectra Disease Activity Levels	The change from Baseline in Vectra disease activity levels was to be estimated. The assessment measures serum protein biomarkers associated with RA. It has a range from 1-100 with lower scores indicating the better outcome.	Baseline, 12 weeks, 24 weeks	No
Secondary	Number of Participants With Positive Etanercept Anti-drug Antibody Status	Blood samples (6 mL) were collected at the baseline, Week 12, and Week 24 visits, or upon early withdrawal, to provide a minimum of 1 mL serum each for ETN ADA and ETN neutralizing antibody analyses. Samples which were positive for ETN anti-drug antibodies were then also tested for ETN neutralizing antibodies.	Baseline, 12 weeks, 24 weeks	No
Secondary	Number of Participants With Positive Etanercept Neutralizing Anti-drug Antibody Status	Blood samples (6 mL) were collected at the baseline, Week 12, and Week 24 visits, or upon early withdrawal, to provide a minimum of 1 mL serum each for ETN ADA and ETN neutralizing antibody analyses. Samples which were positive for ETN anti-drug antibodies were then also tested for ETN neutralizing antibodies.	Baseline, 12 weeks, 24 weeks	No
