Eligibility Criteria  ICMJE

Inclusion criteria:

  • Diagnosed with PsA as defined by:

    • Presence of psoriasis with at least one 2 cm plaque AND
    • One of the five functional classifications of PsA
  • Functional Class I, II, or III as defined by the ACR Classification of Functional Status in Rheumatoid Arthritis
  • Moderate to severe disease, defined as follows:

    • At least 3 tender and 3 swollen joints (78 joint count for tenderness and 76 joints for swelling; AND
    • Either ESR ≥ 28 mm/hr, CRP ≥ 1.5 mg/dL, or morning stiffness for ≥ 30 minutes.
  • Currently taking at least one of the following systemic therapies for PsA: pre-existing stable doses of NSAIDs, corticosteroids (≤ 10 mg/day), and either sulfasalazine (≤ 3 gm/day) or methotrexate (≥ 7.5 and ≤ 30 mg/week) but not both.
  • 18 to 80 years of age.
  • Body weight ≤ 125 kg (275 lbs).
  • Candidate for systemic immunomodulatory therapy.
  • Using an acceptable method of birth control.
  • If female, must have a negative serum pregnancy test during screening period, must be surgically sterile, or must be at least five years postmenopausal.
  • Informed about the study and signed an informed consent prior to performance of any study-related procedure.

Exclusion criteria:

  • Previous treatment with efalizumab.
  • Rheumatoid Factor positive without dactylitis or positive X-rays of the hands or feet, or with rheumatoid nodules.
  • History of joint replacement surgery within 60 days prior to the start of study drug dosing.
  • Joint replacement therapy planned within nine months subsequent to the start of study drug dosing.
  • Intra-articular cortisone injections within 28 days prior to the start of study drug dosing.
  • Pregnancy or lactation.
  • History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies. Respiratory distress (dyspnea, oxygen desaturation with pO2 < 90% or onset of acute respiratory distress syndrome), flank or back pain, and/or hypotension may be signs of anaphylaxis.
  • Active bacterial, viral, fungal, mycobacterium tuberculosis or atypical mycobacterium infection.
  • Positive PPD test unless subject with positive PPD test completed a course of treatment for tuberculosis
  • History of any opportunistic infection.
  • History of a malignancy within the past five years. Subjects with a history of fully resolved, resected, basal or squamous cell carcinoma may be enrolled.
  • Received any vaccine within 28 days prior to the start of study drug dosing.
  • Chronic disorders apart from PsA affecting the joints, such as systemic lupus erythematosus, rheumatoid arthritis, gout, scleroderma or known reactive arthritis (e.g., Reiter's syndrome).
  • COPD, asthma, or other pulmonary disease requiring more therapy than using one inhaler 4× daily.
  • Failed to respond or maintain response to Enbrel.
  • Received any DMARD other than methotrexate or sulfasalazine during the 28 days prior to the start of study drug dosing.
  • Approved biologic PsA therapy during the 28 days or seven half-lives of the drug prior to the start of study drug dosing, whichever is the greater length of time; Enbrel within 42 days prior to the start of study drug dosing.
  • Investigational drug and/or treatment during the 28 days or 7 half-lives of the drug prior to the start of study drug dosing, whichever is the greater length of time.
  • Any condition which, in the opinion of the Investigator, would jeopardize the subject's safety following exposure to efalizumab.
  • Liver disease (e.g., hepatitis, cirrhosis) or abnormal hepatic function (AST or ALT ≥ 2.5

    • ULN).
  • Serum creatinine level ≥ 1.5 mg/dL
  • Platelet count ≤ 125,000 cells/mm3
  • WBC count ≤ 3,500 cells/mm3
  • Total lymphocyte count ≤ 1000 cells/mm3
  • Seropositive for hepatitis B
  • Seropositive for hepatitis C antibody
  • Seropositive for HIV
  • Antinuclear antibodies titer ≥ 1:80
  • History of inflammatory bowel disease
