- Active infections or other illnesses that precludes chemotherapy administration or
patient compliance.

- Pregnant or lactating women.

- Patients who have received any other investigational agents in the last 3 weeks prior
to the start of treatment.

- Patients with the following conditions will be excluded:

- myocardial infarction or stroke within 6 months

- unstable angina pectoris or acute ischemic changes on ECG

- history of diabetic retinopathy

- symptomatic peripheral arterial disease

- major surgery in the last 30 days

- Patients with uncontrolled diarrhea despite optimal medication and those with any

- Patients with impaired cardiac function or clinically significant cardiac diseases,
including any one of the following:

- left ventricular ejection fraction (LVEF) < 45% as determined by multigated
acquisition (MUGA) scan or echocardiogram;

- complete left bundle branch block;

- obligate use of a cardiac pacemaker;

- congenital long QT syndrome;

- history or presence of ventricular tachyarrhythmia;

- presence of unstable atrial fibrillation (ventricular response > 100 bpm).
