Recruitment Details |
This study was conducted at 92 centers in 12 countries in Europe, North America and Latin America. The first participant enrolled on 24 October 2013 and the last participant enrolled on 26 May 2014. |
Pre-assignment Details | Participants were randomized 1:1 to receive either ABP 501 or adalimumab at 40 mg every 2 weeks for 22 weeks. Randomization was stratified by geographic region and prior biologic use for rheumatoid arthritis (capped at 40% of the study population). |

Measure Description: The participant's overall assessment of their disease activity in the past week on a 0 to 10 horizontal scale. The left-hand extreme of the scale was described as "no RA activity at all" (symptom-free and no arthritis symptoms; score = 0) and the right-hand extreme as "worst RA activity imaginable" (maximum arthritis disease activity; score = 10).

[1]
Measure Description:
The HAQ-DI questionnaire asks participants to rate their level of difficulty on daily activities as well as their use of aids, devices, or help from another person for these activities and disabilities. Responses are scored from 0 indicating no difficulty to 3 indicating inability to perform a task in that area. The overall score is the average of each of the 8 category scores and ranges from 0 (no disability) to 3 (very severe, high-dependency disability). Data are available for 263 and 261 participants in each group respectively. |

Measure Description:
The DAS28-CRP is a composite score to measure disease activity in patients with RA, derived from the following variables:
DAS28-CRP scores range from approximately zero to ten. Higher scores indicate higher disease activity. Data are available for 264 and 261 participants in each group respectively. |
