| Primary | Number of Participants With an American College of Rheumatology (ACR) 20 Response at Week 12 | ACR 20 response is an improvement of greater than or equal to 20 percentage in both tender and swollen joint count and in 3 to 5 assessments (patient's assessment of pain visual analog scale [VAS] with 0, no pain to 10, worst pain; patient's and physician's global assessment of disease activity VAS scales: overall disease activity [0, very well to 10, very poor and 0, no arthritis activity to 10, extremely active, respectively]; Health Assessment Questionnaire [HAQ]: 20-questions on life activities [0, no difficulty to 3, inability to perform a task]; C-reactive protein[CRP]). | Intent to treat. All participants randomized were included in the analysis according to the assigned treatment groups. Participant is considered a non- responder if the participant has used any pre-specified prohibited medications or discontinued due to lack of efficacy or participant who have no data for all ACR components at Week 12. | Posted | | Number | | Participants | | Week 0 to Week 12 | | | | ID | Title | Description |

| OG000 | Group I: Placebo | Participants received subcutaneous (SC) placebo injection at Weeks 0, 1,2, and 3. At Week (Wk) 12 and Wk 16, placebo participants crossed over to receive ustekinumab (CNTO 1275) SC. | | OG001 | Group II: Ustekinumab x 4 | Participants received SC injection of ustekinumab 90 mg at Wk 0,1,2, and 3. At Wk 12 and Wk 16, participants received placebo SC to maintain the blind. After the first 36 participants were randomized, Centocor became aware that some vials of other study agents not used in this study contained black particulate matter and the filtration procedure was implemented. The resulting dose of ustekinumab after filtration was approximately 0.70 mL, equivalent to 63 mg. |

| Hypothesis: No difference between ustekinumab x 4 and placebo at a significant level of 0.05. Sample Size and power: With 70 partcipants in each treatment group, 5000 repetitions. Assuming a 20% ACR20 response in placebo participants regardless of prior anti-TNF exposure and a 35% ACR 20 and 45% ACR20 response in ustekinumab group for participants who had prior anti-TNF exposure, and who had no prior anti-TNF exposures, the power to detect the treatment difference is 0.85. | Cochran-Mantel-Haenszel (CMH) chi-square | Stratified by subject's prior anti-Tumor Necrosis Factor (TNF) exposure status (Yes/No). | <0.001 | The study is designed to maintain a Type I error of 0.05 or less for the primary analysis | | | | | | 95 | | | | | |

| Secondary | Change in Health Assessment Questionnaire (HAQ) at Week 12 | The HAQ is a 20-question instrument assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area based on the worst score from the questions that pertain to that task. The HAQ score is determined by the average of the 8 scores. | Participants were included in the analysis according to the assigned treatment groups. Zero change is imputed if the participant has used any pre-specified prohibited medications or discontinued due to lack of efficacy. Other missing data were not imputed. | Posted | | Median | Inter-Quartile Range | Scores on scale | | Week 0 to Week 12 | | | | ID | Title | Description |
