- Received an immunization within 4 weeks prior to enrollment.

- History of autoimmune disease including psoriasis, inflammatory bowel disease.

- Medical history of transplantation (solid organ or bone marrow).

- Received an investigational drug in the past 30 days other than Food and Drug Administration (FDA) sanctioned treatment IND antiretroviral agents.

- Renal insufficiency with a serum creatinine level greater than 1.5 times the upper limit of normal.

- Bone marrow suppression as defined by one or more of the following: granulocyte count less than 1,000 cells/µL; hemoglobin less than 9.0g (females) or less than 9.5g (males); or platelet count less than 75,000 cells/µL.

- Evidence of hepatic disease indicated by one or more of the following: SGOT (AST) and/or SGPT (ALT) greater than 5 times the upper limit of normal. Bilirubin greater than 2 times the upper limit of normal (except for patients with known Gilbert's syndrome or those receiving indinavir who may be enrolled if the serum bilirubin is less than or equal to 5 times the upper limit of normal).

- Active cardiac disease (coronary artery disease, congestive heart failure or cardiomyopathy) requiring treatment with any of the following medications: antiarrhythmic agents including digitalis, anti-anginal drugs including topical or systemic nitrates, calcium channel blockers, and beta blockers, and afterload reducers including ACE inhibitors. Patients requiring any of these medications solely for the treatment of hypertension remain eligible for the study.
