2. uncontrolled or poorly controlled hypertension;

3. recent (within past 2 months) serious surgery or infectious disease;

4. recent history (since enrollment in prior R788 study) of, or treatment for, a
malignancy other than non-melanomatous skin cancer, or any history of lymphoma;

7. known laboratory abnormalities: ALT > 1.2 x ULN, creatinine >1.5x ULN, an ANC
<2,500/mm3 or 2.5 x 109/L, lymphocyte count < 600/mm3 or 0.6 x 109L, Hgb < 9 g/dL
or 5 mmol/L, platelet count <125,000/mm3 or 125 x 109/L are excluded.

- The patient has a history of substance abuse, drug addiction or alcoholism. Patients
