Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Dose CFZ533 in Rheumatoid Arthritis Patients

This was a Healthy Volunteer only study originally, but after an amendment to protocol,
rheumatoid arthritis patients will be starting 7-Mar-2014 and thus, the protocol is now
registered.

Inclusion Criteria (for healthy volunteers):

1. Healthy male and surgically sterilized or post-menopausal female subjects 18 to 55
years of age (for Cohort 9 only, subjects must be of Chinese descent)

2. Vital signs (systolic and diastolic blood pressure and pulse rate) should be within
normal limits

3. Weight 50-150 kg and a body mass index (BMI) 18-32 kg/m2

Inclusion Criteria (for rheumatoid arthritis patients):

1. Healthy male and surgically sterilized or post-menopausal female subjects 18 to 55
years of age

2. Fulfilled 2010 ACR/EULAR classification criteria for RA per Investigator

3. Treatment with a stable oral RA treatment regimen for ≥ 4 weeks before randomization

4. Systemic corticosteroids allowed if on a stable dose (≤ 10 mg/day of prednisone or
equivalent) ≥ 4 weeks prior to randomization

5. Subjects taking NSAIDs (COX-1 or COX-2 inhibitors) as part of their RA therapy must be
on a stable dose for at least 4 weeks before randomization

Exclusion Criteria (for healthy volunteers):

1. History of hypersensitivity to vaccines, the study drug, or to drugs of similar
chemical classes (i.e., biologic agents)

2. Abnormal hematology, coagulation or inflammatory lab results

3. History or evidence of tuberculosis.

Exclusion Criteria (for rheumatoid arthritis patients):

1. Use of anti-TNF or other biologics in previous 3 months

2. Any intra-articular injection therapy (e.g., corticosteroid, hyaluronan) required for
treatment of acute RA flare within 4 weeks before randomization

3. Previous treatment with a B cell-depleting biologic agent or any other
immunomodulatory biologic agent within 5 half-lives (experimental or approved)

4. Current treatment with cyclophosphamide

5. Autoimmune disease other than RA

6. Adult juvenile rheumatoid arthritis

7. RA functional status class IV according to the ACR 1991 revised criteria
