Eligibility Criteria

Inclusion

  • Subjects had to satisfy the following criteria before randomization into the study:
  • Active PsA at the time of screening, including ≥ 3 swollen joints and ≥ 3 tender/painful joints. • Had ≥ 1 of the following subtypes of PsA: distal interphalangeal (DIP) involvement; polyarticular arthritis (absence of rheumatoid nodules and presence of psoriasis); arthritis mutilans; asymmetric peripheral arthritis; or ankylosing spondylitis-like.
  • Arthritis had demonstrated an inadequate response to nonsteroidal antiinflammatory drug (NSAID) therapy.
  • Subjects had plaque psoriasis with qualifying target lesion. Target lesion was to be ≥ 2 cm in diameter and could not be on the scalp, axilla, or groin. Psoriasis was to be stable (ie, not accelerating).
  • Between 18 and 70 years of age.
  • Subjects remaining on concomitant MTX (≤ 25 mg/week) had inadequate disease control in the opinion of the investigator and had been on a stable dose of MTX for 2 months before start of investigational product. Subjects were required to maintain a stable dose of MTX throughout the study.
  • Negative serum pregnancy test within 14 days before the first dose of investigational product in all women (except those surgically sterile or ≥ 5 years postmenopausal).
  • Heterosexually active men and women of childbearing potential agreed to use a medically accepted form of contraception throughout the study, including the exclusionary medicine washout period and follow-up period.
  • Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) ≤ 2 times laboratory's upper limit of normal; hemoglobin ≥ 8.5 g/dL; platelet count ≥ 125,000/mm3; white blood cell count ≥ 3,500 cells/mm3; and serum creatinine ≤ 2 mg/dL.
  • Negative HIV test. Negative test for hepatitis B surface antigen and hepatitis C.
  • Able to reconstitute and self-inject investigational product or have a designee who could do so.
  • Capable of understanding and giving written, voluntary informed consent.

Exclusion

  • Guttate or pustular psoriasis.
  • Evidence of skin conditions (eg, eczema) other than psoriasis that would interfere with evaluations of the effect of study medication on psoriasis.
  • Active severe infection within 1 month of investigational product administration.
  • Subjects must be off antibiotics for 1 week before investigational product administration.
  • Previous receipt of etanercept, known antibody to TNF, or experimental metalloproteinase inhibitors (past or current use of minocycline and doxycycline was acceptable).
  • Receipt of investigational drugs or biologics within 4 weeks of the screening visit.
  • Receipt of anti-CD4 or diptheria IL-2 fusion protein within the previous 6 months, with a subsequent abnormal absolute T cell count.
  • Psoralen ultraviolet A phototherapy (PUVA) within 4 weeks of investigational product initiation. Ultraviolet B (UVB) phototherapy within 2 weeks of investigational product initiation.
  • Receipt of disease-modifying anti-rheumatic drugs (DMARDs) other than MTX (eg, hydroxycholorquine, oral or injectable gold, cyclophosphamide, cyclosporine, azathioprine, D-penicillamine, or sulfasalazine) or intra-articular corticosteroids within 4 weeks before the first dose of investigational product.
  • Dose of NSAID greater than the maximum recommended dose in the product information. NSAID dose had to be stable for ≥ 4 weeks before screening evaluation.
  • Concomitant corticosteroids \> 10 mg/day of prednisone (or its equivalent). Corticosteroid dose had to be stable for ≥ 4 weeks before screening evaluation.
  • Topical steroids, oral retinoids, topical vitamin A or D analog preparations or anthralin within 14 days of baseline. (Exception: Topical therapies were permitted on scalp, axillae, and groin but had to be stable throughout trial.)
  • Pregnancy or lactation in women.
  • Significant concurrent medical diseases including:
  • Diabetes mellitus requiring insulin
  • Uncompensated congestive heart failure
  • Myocardial infarction within 12 months of screening visit
  • Unstable or stable angina pectoris
  • Uncontrolled hypertension
  • Severe pulmonary disease (requiring medical or oxygen therapy)
  • History of cancer (other than resected cutaneous basal or squamous cell carcinoma or in situ cervical cancer) within 5 years of screening visit
  • HIV positive, hepatitis B surface antigen, or hepatitis C positive
  • Rheumatoid arthritis, systemic lupus, scleroderma, or polymyositis
  • Any condition judged by the subject's physician that would cause this study to be detrimental to the subject
  • Current or history of psychiatric disease that would interfere with ability to comply with the study protocol or give informed consent.
  • History of alcohol or drug abuse that would interfere with ability to comply with the study protocol.
