A Study of the Safety and Effectiveness of Lyophilized Certolizumab Pegol in the Treatment of Signs and Symptoms of Rheumatoid Arthritis and in Prevention of Joint Damage in Patients With Active Rheumatoid Arthritis

An AE is any untoward medical occurrence in a subject or trial subject that is administered a drug or biologic (medicinal product) or that is using a medical device. The event does not necessarily have a causal relationship with that treatment or usage.

First dose of Certolizumab Pegol (CZP) was at Baseline of the preceding double-blind study [NCT00152386] for subjects randomized to CZP, or at Entry Visit (Week 0) of this study for subjects randomized to Placebo.

A SAE is any untoward medical occurrence that at any dose:

• Results in death
• Is life-threatening
• Requires in patient hospitalisation or prolongation of existing hospitalisation
• Results in persistent or significant disability/incapacity, or
• Is a congenital anomaly or birth defect
• Is as infection that requires treatment parenteral antibiotics
• Other important medical events which based on medical or scientific judgement may jeopardise the patients, or may require medical or surgical intervention to prevent any of the above

First dose of CZP was at Baseline of the preceding double-blind study [NCT00152386] for subjects randomized to CZP, or at Entry Visit (Week 0) of this study for subjects randomized to Placebo.

An AE is any untoward medical occurrence in a subject or trial subject that is administered a drug or biologic (medicinal product) or that is using a medical device. The event does not necessarily have a causal relationship with that treatment or usage. The results of this Primary Outcome Measure are summarized from the Adverse Event pages of the Case Report Forms.

The mTSS quantifies the extent of bone erosions and joint space narrowing for 44 and 42 joints, respectively, as assessed by x-rays of the hands and feet. The score ranges from 0 to 448 with higher scores representing greater damage. A negative value in mTSS change from Baseline indicates an improvement from Baseline. The higher the negative value the better the improvement.

The HAQ-DI assesses the degree of difficulty experienced in eight domains (Dressing and Grooming, Arising, Eating, Walking, Hygiene, Reach, Gripping, Other Activities) of daily living activities using 20 questions. The HAQ-DI is calculated by summing the domain scores and dividing them by the number of domains. It ranges from 0 (no difficulty) to 3 (unable to do). Negative values indicate an improvement from Baseline to the Post-Baseline Visit with larger negative values showing a better improvement.

Morning stiffness is defined as the time in hours elapsed between the time of usual awakening (even if not in the morning) and the time the subject is as limber as he/she will be during a day involving typical activities. A negative value in duration of morning stiffness change from Baseline indicates an improvement from Baseline. The higher the negative value the better the improvement.

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. A negative value in DAS28[ESR] change from Baseline indicates an improvement from Baseline.

Good EULAR response is defined as Disease Activity Score 28 [Erythrocyte Sedimentation Rate] (DAS28[ESR]) improvement from Baseline of the preceding double-blind study > 1.2 and DAS28[ESR] value < 3.2.

The SF-36 is a 36-item generic health status measure that measures 8 general health concepts: Physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Each domain of the eight domains and the summary concept PCS score are scored to yield values between 0 (worst) and 100 (best).

The SF-36 is a 36-item generic health status measure that measures 8 general health concepts: Physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Each domain of the eight domains and the summary concept MCS score are scored to yield values between 0 (worst) and 100 (best).
