revised 1987 American College of Rheumatology criteria.
3. Able to receive treatment on an outpatient basis
4. Have received MTX for at least 12 weeks immediately prior to baseline, of which
the last 8 weeks prior to baseline must have been at a stable dose of between 7.5
and 25 mg/week (oral or parenteral). Patients who have partially responded MTX,
but discontinued treatment for surgery or pregnancy may reinitiate treatment at least

5. All DMARDs, other than MTX will be withdrawn prior to baseline (see Inclusion
#7 and Exclusion #12)

4 weeks prior to baseline
7. Prior to randomization, will have discontinued etanercept for = 2 weeks, infliximab
or adalimumab for = 8 weeks, anakinra for = 1 week, or abatacept for = 8 weeks
(see exclusion #9); discontinuation of leflunomide for =12 weeks (or =4 weeks after
11 days of standard cholestyramine washout).
8. Swollen joint count (SJC) = 6 (66 joint count) and tender joint count (TJC) = 6 (68
joint count) at screening (Week -3) and baseline
9. At screening HS-CRP = 1.0 mg/dL (10 mg/L) or ESR = 28 mm/hr
10. Palpable carotid and femoral pulse at screening
11. 18 years = Age = 75 years
12. Must be willing to receive oral folate at a minimum dose of 5 mg/week
13. Females of child-bearing potential and males with female partners of child-bearing potential may participate in this trial only if using a reliable means of contraception
(e.g. physical barrier (patient and partner), contraceptive pill or patch, spermicide
and barrier, or IUD)
14. If female and of childbearing potential, the patient must have a negative urine
pregnancy test within three weeks prior to baseline
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes

pulmonary fibrosis or Felty’s syndrome). Sjögren’s Syndrome with RA is allowable
3. Functional class IV as defined by the ACR Classification of Functional Status in
RA

5. Patients weighing >150 kg
6. Patients with uncontrolled co-morbidities, such as diabetes (insulin-dependent),
hypertension (systolic blood pressure > 150 mm Hg or diastolic blood pressure >
100 mm Hg), CAD or CHF, or current atrial fibrillation and cardiac conditions
precluding accurate evaluation of PWV and/or safety
7. Secondary causes of hyperlipidemia, such as uncontrolled primary hypothyroidism

11. Initiation of treatment with lipid-lowering agents within 12 weeks prior to baseline; treatment with lipid lowering agents must be at a stable dose within this period
12. Initiation of oral anti-diabetes or anti-hypertensive medication dose within 12
weeks prior to baseline; treatment with anti-hypertensive agents must be at a stable dose within this period
