- Radiotherapy =28 days prior to starting study drug, or =14 days prior to starting
study drug in the case of localized radiotherapy (eg, for analgesic purpose or
for lytic lesions at risk of fracture), or who have not recovered from
radiotherapy toxicities to Grade 1.
2. Subject who have impairment of gastrointestinal (GI) function or GI disease that may

dose), uncontrolled arterial hypertension (>160/100 mm/Hg on antihypertensive
medications), chronic pulmonary disease requiring oxygen, known bleeding disorders,
uncontrolled endocrine diseases, altered mental status or psychiatric illness/social

Hepatitis B or C, or cirrhosis.
7. Symptomatic or uncontrolled brain metastases requiring current treatment (less than 28
days from last cranial radiation or 28 days from last steroids use).
