Open Label Extension for Patients Coming From the Dosing Flexibility Study in Patients With Rheumatoid Arthritis (RA)

A TEAE is defined as any untoward medical occurrence (eg, noxious or pathological changes) in a subject or clinical investigation subject compared with pre-existing conditions, that occurs during any phase of a clinical trial including Pretreatment, Run-In, Wash-Out, or Follow-Up Phases.

A TEAE is defined as being independent of assumption of any causality (eg, to trial or concomitant medication, primary or concomitant disease, or trial design).

TEAEs are all AEs in which the onset date and time is after the first study drug administration in C87084, up to 84 days after the last injection.

A Serious Adverse Event is any untoward medical occurrence that at any dose

• results in death,
• is life threatening,
• requires in-patient hospitalization or prolongation of existing hospitalization,
• results in persistent or significant disability/incapacity
• is a congenital anomaly/birth defect

ACR20 response is defined for subjects with at least 20% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) Health Assessment Questionnaire-Disability Index (HAQ-DI), 2) C-reactive Protein (CRP), 3) Patient's Assessment of Arthritis Pain-Visual Analog Scale, 4) Patient's Global Assessment of Disease Activity, 5) Physician's Global Assessment of Disease Activity.

ACR50 response is defined for subjects with at least 50% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) Health Assessment Questionnaire-Disability Index (HAQ-DI), 2) C-reactive Protein (CRP), 3) Patient's Assessment of Arthritis Pain-Visual Analog Scale, 4) Patient's Global Assessment of Disease Activity, 5) Physician's Global Assessment of Disease Activity.

ACR70 response is defined for subjects with at least 70% improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) Health Assessment Questionnaire-Disability Index (HAQ-DI), 2) C-reactive Protein (CRP), 3) Patient's Assessment of Arthritis Pain-Visual Analog Scale, 4) Patient's Global Assessment of Disease Activity, 5) Physician's Global Assessment of Disease Activity.

DAS28(ESR) is calculated using the tender joint count (TJC), swollen joint count (SJC) erythrocyte sedimentation rate (ESR in mm/hour), and the Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in mm) using the following formula: 0.56 x √(TJC) + 0.28 x √(SJC) + 0.70 x lognat (ESR) + 0.014 x Global Assessment of Arthritis where 28 joints are examined and a lower score indicates less disease activity. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

< 2.6 Remission,

> = 2.6 - < =3.2 Low, > 3.2 - < = 5.1 Moderate, > 5.1 High.

SDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), C-reactive protein (CRP in mg/dL), Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm), and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined where a lower score indicates less disease activity. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

<= 3.3 Remission, > 3.3 - <= 11 Low, > 11 - <= 26 Moderate, > 26 High.

CDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm), and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

The range for the CDAI is 0 - 76 with a negative change in CDAI score indicating an improvement in disease activity and a positive change in score indicating a worsening of disease activity.

DAS28(ESR) is calculated using the tender joint count (TJC), swollen joint count (SJC) erythrocyte sedimentation rate (ESR in mm/hour), and the Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in mm) using the following formula: 0.56 x √(TJC) + 0.28 x √(SJC) + 0.70 x lognat (ESR) + 0.014 x Global Assessment of Arthritis where 28 joints are examined and a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI).

< 2.6 (Remission),

> = 2.6 - < =3.2 Low, > 3.2 - < = 5.1 Moderate, > 5.1 High.

SDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), C-reactive protein (CRP in mg/dL), Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm), and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI).

CDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), Patient's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm), and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined where a lower score indicates less disease activity. Missing values were imputed using Non-Responder Imputation (NRI).

The range for the CDAI is 0 - 76 with a lower CDAI score indicating improvement in activity and a higher score indicating a decline activity.

HAQ-DI is derived based on the mean of individual scores in 8 categories of daily living actives (using 20 questions). Each question is scored 0-3 (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do). Thus, the mean also has a range from 0-3. Change from Baseline is computed as the value at Completion/Withdrawal minus the Baseline value. A negative value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

Change from Baseline in Fatigue Assessment scale (0 to 10, 0 is "No Fatigue" and 10 is "Fatigue as bad as you can imagine") is computed as the value at Completion/Withdrawal minus the Baseline value. A negative value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

There are 8 SF-36 domain scores: Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional and Mental Health, each ranging from 0 to 100, with higher scores indicating better health. A larger positive value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

PCS norm-based scores are calculated based upon the following 8 domain scores, Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional and Mental Health, and range from 1 to 81, where 50 represents the normative value. A larger positive value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

A larger positive value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

Change from Baseline in Patient's Assessment of Arthritis Pain-VAS (0 to 100 mm visual analog scale, 0 being no pain and 100 being most severe pain) is computed as the value at Completion/Withdrawal minus the Baseline value. A negative value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.

Change from Baseline in Patient's Global Assessment of Disease Activity-VAS (0 to 100 mm visual analog scale, 0 being no symptoms and 100 being severe symptoms) is computed as the value at Completion/Withdrawal minus the Baseline value. A negative value in change from Baseline indicates an improvement. This analysis was carried out using the Last Observation Carried Forward (LOCF) method.
