Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 16 | The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability. | Baseline and Week 16 |

Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability. | Baseline and Week 24 | 
| Change From Baseline in the Medical Outcome Study Short Form 36-item (SF-36) Physical Functioning Domain at Week 16 | The Medical Outcome Study Short Form 36-Item Health Survey, Version 2 (SF-36) is a self-administered instrument that measures the impact of disease on overall quality of life and consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health). The concepts measured by the SF-36 are not specific to any age, disease, or treatment group, allowing comparison of relative burden of different diseases and the relative benefit of different treatments. Norm-based scores were used in analyses, calibrated so that 50 is the average score and the standard deviation equals 10. Higher scores indicate a higher level of functioning. The physical functioning domain assesses limitations in physical activities because of health problems. A positive change from baseline score indicates an improvement. | Baseline and Week 16 |

The CDAI score ranges from 0-76 where lower scores indicate less disease activity. The following thresholds of disease activity have been defined for the CDAI: Remission: ≤ 2.8; Low Disease Activity: > 2.8 and ≤ 10; Moderate Disease Activity: > 10 and ≤ 22; High Disease Activity: > 22 | Baseline and Week 16 |

The 68 tender joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, meta-carpophalangeal, proximal interphalangeal and distal interphalangeal; lower: hip, knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal. | Baseline and Week 16 | 
| Percentage Change From Baseline in the Swollen Joint Count at Week 16 | Joint swelling is soft tissue swelling that is detectable along the joint margins and is assessed by inspection and direct palpation of the joint, by the examiner. The ACR 66 swollen joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, metacarpophalangeal, proximal interphalangeal and distal interphalangeal; lower: knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal. | Baseline and Week 16 | 
| Percentage Change From Baseline in the Subject Assessment of Pain at Week 16 | The Subject Assessment of Pain was measured asking the participant to place a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents no pain, and the right-hand boundary (score = 100 mm) represents pain as severe as can be imagined.

The distance from the mark to the left-hand boundary was recorded in millimeters. | Baseline and Week 16 | 
| Percentage Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Week 16 | The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3).

| Percentage Change From Baseline in the High Sensitivity C-Reactive Protein (CRP) at Week 16 | C-Reactive Protein (CRP) is a substance produced by the liver that increases in the presence of inflammation in the body. An elevated CRP level is identified with blood tests and is considered a non-specific marker for disease. | Baseline and Week 16 | 
| Percentage Change From Baseline in Erythrocyte Sedimentation Rate (ESR) at Week 16 | The erythrocyte sedimentation rate (ESR) is a blood test that can reveal inflammatory activity. The subject's blood is placed in a tall, thin tube, red erythrocytes gradually settle to the bottom. Inflammation can cause the cells to clump together. Because these clumps of cells are denser than individual cells, they settle to the bottom more quickly. The ESR test measures the distance red blood cells fall in a test tube in one hour. The farther the red blood cells have descended, the greater the inflammatory response. | Baseline and Week 16 |

A positive change from baseline score indicates an improvement. | Baseline and Week 16 |
