Clinical Trial Summary

The purpose of this study is to assess the efficacy of sirukumab as measured by the reduction of the signs and symptoms of rheumatoid arthritis (RA) and inhibition of radiographic progression in patients with active RA who are unresponsive to treatment with disease-modifying antirheumatic drugs (DMARD).

Description:

Patients will be randomly assigned to treatment groups, and they and study personnel will not know the identity of the treatments given. Some patients will receive a placebo, which resembles a medication, but does not contain an active substance. This helps to determine if the study agent is effective. Patients will receive placebo or sirukumab by injection under the skin. The expected duration of the study is 120 weeks, which includes 104 weeks of treatment. Participants who complete participation in the study will be eligible for inclusion into the long-term safety and efficacy study, if enrollment at a participating site is available to them. If they do not participate in the long-term study, they will continue into the safety follow-up for approximately 16 weeks. The placebo-controlled portion of the study is through Week 52, when placebo patients will cross over to one of two sirukumab dose regimens. Patient safety will be monitored throughout the study.

Participants were analyzed according to randomized treatment groups they were assigned, regardless of treatments they actually received. Here, TF= treatment failure.	Week 16
Primary	Change From Baseline in Van Der Heijde-modified Sharpe (vdH-S) Score at Week 52	The van der Heijde-modified Sharpe (vdH-S) score is defined as a measurement of progression in structural damage. It is the sum of joint erosion (32 joints of the hands and 12 joints of the feet) score and joint space narrowing (JSN) (30 joints of the hands and 12 joints of the feet) score. The joint erosion assessment is scored according to the surface area involved, from 0 to 5, with 0 indicating no erosion and 5 indicating complete collapse of bone whereas the JSN assessment including subluxation, is scored from 0 (normal) to 4 (bony ankylosis or complete luxation). The total score ranges from 0 (best) to 448 (worst) with higher scores indicating more joint damage. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received. Here, EE= early escape.	Baseline, Week 52
Secondary	Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Week 24	The Health Assessment Questionnaire-Disability Index (HAQ-DI) score is an evaluation of the functional status for a participant.

Overall score computed as sum of domain score divided by number of domains answered. Total possible score range 0= least difficulty to 3= extreme difficulty. AUC of change from baseline in HAQ-DI score is AUC of change from baseline in HAQ-DI score versus time. AUC was calculated based on measurement (observed HAQ-DI score change from baseline) at scheduled visits using trapezoidal rule.Functional status was determined as cumulative measure of HAQ-DI over 1 year by using AUC of change from baseline in HAQ-DI score through week 52. Decreases in AUC of change from baseline in HAQ-DI means greater average improvement in physical function over time. Participants analyzed according to randomized treatment groups they were assigned, regardless of treatments they actually received.	Week 0 Through Week 24 and 52

Secondary	Change From Baseline in Van Der Heijde-modified Sharpe (vdH-S) Score at Week 24	vdH-S score is defined as a measurement of progression in structural damage. It is the sum of joint erosion (32 joints of the hands and 12 joints of the feet) score and joint space narrowing (JSN) (30 joints of the hands and 12 joints of the feet) score. The joint erosion assessment is scored according to the surface area involved, from 0 to 5, with 0 indicating no erosion and 5 indicating complete collapse of bone whereas the JSN assessment including subluxation, is scored from 0 (normal) to 4 (bony ankylosis or complete luxation). The total score ranges from 0 (best) to 448 (worst) with higher scores indicating more joint damage. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 24
Secondary	Change From Baseline in Van Der Heijde-modified Sharpe (vdH-S) Sub-score by Type of Damage (Erosion or JSN) at Week 24 and 52	vdH-S score measures structural damage progression as sum of joint erosion(JE) and joint space narrowing(JSN) scores(S).JE is summary of erosion severity in 32 of hands(H) and 12 of feet(F) joints, scored as per surface area- from 0 (no erosion) to 5 (complete(CM) collapse of bone). Maximum (MAX) JES for H-160 (32*5) and MAX JES for F- 120 (12*10 [5*2 sides of foot]). MAX JES is 280 whereas JSN is summary of severity of 30 of H and 12 of F joints, scored to subluxation from 0(normal) to 4(bony ankylosis or CM luxation). MAX JSNS for H-120(30*4), and MAX JSS for F-48(12*4). MAX JSNS is 168.Thus MAX JES-280 combined with MAX JSNS-168 gives worst possible vdH-SS (i.e., JE score + JSN score) of 448. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 24 and 52
Secondary	Change From Baseline in Van Der Heijde-modified Sharpe (vdH-S) Sub-score by Region Hand or Feet and Type Erosion or JSN at Week 24 and 52	vdH-S score measures structural damage progression as sum of joint erosion(JE) and joint space narrowing(JSN) scores(S).JE is summary of erosion severity in 32 of hands(H) and 12 of feet(F) joints, scored as per surface area- from 0 (no erosion) to 5 (complete(CM) collapse of bone). Maximum (MAX) JES for H-160 (32*5) and MAX JES for F- 120 (12*10 [5*2 sides of foot]). MAX JES is 280 whereas JSN is summary of severity of 30 of H and 12 of F joints, scored to subluxation from 0(normal) to 4(bony ankylosis or CM luxation). MAX JSNS for H-120(30*4), and MAX JSS for F-48(12*4). MAX JSNS is 168.Thus MAX JES-280 combined with MAX JSNS-168 gives worst possible vdH-SS (i.e., erosion score + JSN score) of 448. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 24 and 52
Secondary	Percentage of Participants With Change From Baseline in Van Der Heijde Modified Sharpe Score (vdH-S Score) Greater Than Smallest Detectable Change (SDC) at Weeks 24 and 52	vdH-S score measures structural damage progression as sum of joint erosion(JE) and joint space narrowing(JSN) scores(S). JE is summary of erosion severity in 32 of hand and 12 of feet joints, scored according to the surface area, from 0 (no erosion) to 5 (complete collapse of bone) whereas the JSN is summary of severity of 30 of hand and 12 of feet joints, scored according to the subluxation from 0 (normal) to 4 (bony ankylosis or complete luxation). The SDC is smallest change in score that is considered to be assessed correctly based on limits of agreement (that is., above the measurement error). The SDC for change from baseline in vdH-S Score is determined as: SDC=1.96 * SD / (root 2 * root k), where SD is the standard deviation of the difference between 2 readers in change from baseline in vdH-S score; k is the number of readers. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Weeks 24 and 52

Secondary	Change From Baseline in Serum C-reactive Protein (CRP) Levels Through Week 52	Serum CRP is a marker of systemic inflammation. A negative change from baseline in CRP represents improvement. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 2, 4, 6, 8, 12, 16, 18, 20, 24, 28, 32, 36, 40, 44, 48 and 52
Secondary	Change From Baseline in the Duration of Morning Stiffness Through Week 52	Duration of morning stiffness was defined as the time elapsed when participant woke up in the morning and was able to resume normal activities without stiffness in minutes (If none was present = 0; If morning stiffness was continuing at the time of assessment or was unusual compared to the recent past, average of duration of stiffness over the past 3 days was reported; If stiffness persisted the entire day, 1440 minutes was recorded). Negative values for this outcome measure represent improvement, i.e. shortening of duration of morning stiffness. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 2, 4, 6, 8, 12, 16, 18, 20, 24, 28, 32, 36, 40, 44, 48 and 52
Secondary	Change From Baseline in Physical and Mental Component Summary Scores of 36-Item Short Form Health Survey (SF-36) at Weeks 24 and 52	SF-36 questionnaire is health related quality of life (QOL) instrument with 36 questions with 8 multi-item scales (evaluated limitations in): physical functioning due to health problems; usual role activities due to physical health problems; Bodily pain; General mental health (psychological distress and well-being); usual role activities due to personal or emotional problems; social functioning due to physical or mental health problems; Vitality (energy and fatigue); General health perception. Each 8 scales scored from 0 to 100 with higher scores= better health. Based on scale scores, summary scores, physical component score (PCS) and mental component score (MCS) will be derived. Scoring is derived based on algorithm developed in software provided by developer. Summary MCS and PCS score is also scaled from 0 to 100 with higher scores= better health. Participants were analyzed according to randomized treatment groups they were assigned regardless of treatments they actually received.	Baseline, Week 24 and 52
Secondary	Percentage of Participants With Greater Than or Equal to 4-Point Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) Score at Week 8, 16, 24, 36 and 52	The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) is a questionnaire that assesses self-reported tiredness, weakness, and difficulty conducting usual activities due to fatigue. The questionnaire consists of 13 questions that assess a participant's level of fatigue and tiredness over the last 7 days. Each question is graded on a 5-point scale (0 - 4); and accordingly, the total FACIT-Fatigue scores can range from 0 to 52, with lower score reflecting more fatigue and higher scores reflecting less fatigue. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Week 8, 16, 24, 36 and 52
Secondary	Change From Baseline in Total Scores of Work Limitations Questionnaire (WLQ) Week 8, 16, 24, 36 and 52	The Work Limitations Questionnaire (WLQ) was used to measure the impairment in work-related productivity, with reference to the previous two weeks. Each work-related question is scored from 0 to 4 and the total score ranges from 0-100, with lower scores signifying fewer limitations at work. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 8, 16, 24, 36 and 52
Secondary	Change From Baseline in EuroQol Health State Visual Analogue Scale (EQ VAS)	The EuroQol Health State Visual Analogue Scale (EQ VAS) records the respondent's self-rated health on a vertical line, VAS where the endpoints are labeled as 0= 'Worst imaginable health state' and 100= 'Best imaginable health state'. The EQ VAS can be used as a quantitative measure of health outcome as judged by the individual respondents. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	Baseline, Week 8, 16, 24, 36 and 52
Secondary	Change From Baseline in EuroQol EQ-5D-3L Descriptive System	The EQ-5D-3L Descriptive System comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension is assessed on a 3-point ordinal scale (1=no problems, 2=some problems, 3=extreme problems). The responses to the five EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 to 1, with 1.00 indicating "full health" and 0 representing dead. Participants were analyzed according to the randomized treatment groups they were assigned to, regardless of the treatments they actually received.	at Week 8, 16, 24, and 52
