- Patients with gastrointestinal abnormalities including: inability to take oral

affecting absorption will be excluded.

- A serious uncontrolled medical disorder or active infection which would impair their

anticancer therapy and a 30-day wash-out period is allowed.

- Exposure to other investigational agents within 30 days of study inclusion

- Patients with a "currently active" second malignancy, other than nonmelanoma skin
cancer and carcinoma in situ of the cervix, should not be enrolled. Patients would
not be considered to have a "currently active" malignancy if they have completed
therapy for a prior malignancy, are disease free from prior malignancies for >5 years
or are considered by their physician to be at less than 30% risk of relapse.

- Patients with history of pulmonary embolism who are not receiving anticoagulation,
