• Have a history of hypersensitivity to efalizumab or any of its components

• Are using any excluded therapy

• Have a history of or ongoing alcohol or illegal drug abuse

• Have a history of or an ongoing uncontrolled serious bacterial, viral, fungal, or atypical mycobacterial infection. This includes diagnoses that required more than 2 weeks of therapy, such as endocarditis and osteomyelitis, that have been treated in the past 6 months. In addition, if the patient is currently receiving antibiotics, antivirals, or antifungals for an infection or for suppression or prophylaxis for any diagnosis, the patient will be excluded.

• Have any history of opportunistic infections (e.g., systemic fungal infections, parasites)

• Are seropositive for hepatitis B antigen, hepatitis C antibody, or human immunodeficiency virus (HIV). Patients will undergo testing during screening, and any patients who are seropositive for hepatitis B antigen, hepatitis C antibody, or HIV will be excluded.

• Have a history of active tuberculosis or are currently undergoing treatment for tuberculosis. A purified protein derivative (PPD) test or chest x-ray will be performed at the screening visit. Patients with a positive PPD test (not due to BCG vaccination) or chest x-ray will be excluded.

• Have the presence or history of malignancy within the past 5 years, including lymphoproliferative disorders. Patients with a history of fully resolved basal or squamous cell skin cancer may be enrolled.

• Have a history of hemolytic anemia

• Have a history of clinically significant anemia

• Have a WBC count <4,000 cells/uL or >14,000 cells/uL

• Have a hematocrit (HCT) <30% or a hemoglobin (Hgb) level <11 g/dL

• Have a platelet count <150,000 cells/uL

• Have hepatic enzyme levels =3 times the upper limit of normal

• Have a serum creatinine level =2 times the upper limit of normal

• Have been exposed to any experimental drugs or treatments within 30 days or 5 half-lives, whichever is longer, prior to the screening visit

• Have had any previous exposure to efalizumab

• Have been vaccinated with a live virus or live bacteria within the 14 days prior to the first dose of efalizumab

• Have any medical condition that, in the judgment of the investigator, would jeopardize the patient's safety following exposure to study drug (efalizumab or placebo equivalent) or would significantly interfere with the patient's ability to comply with the provisions of this protocol
