* Has not received prior bevacizumab treatment.
* Has been treated with the following prior to randomization: chemotherapy, immunotherapy, investigational agent treatments for disease under study within 28 days before first dose of study drug, radiotherapy not completed at least 2 weeks prior to first dose of study drug, hormonal anticancer therapies within 7 days of first dose of study drug, and systemic, inhaled, or prescription strength topical corticosteroids within 21 days of first dose of study drug.
* Has received wide-field radiation to more than 25% of marrow-bearing areas.

* Has clinically significant uncontrolled condition(s) or condition which, in the opinion of the Investigator, may confound the results of the trial or interfere with the patient's safety or participation.
* Has current chronic/active infection with human immunodeficiency virus or current chronic/active infection with hepatitis C virus or hepatitis B virus.
* Has any untreated or symptomatic central nervous system (CNS) metastases.
* Patients with a history of other malignancy within 3 years prior to randomization.
* Is taking a concomitant medication that is a strong cytochrome P450 (CYP)3A inhibitor or strong CYP3A inducer, or that is a substrate of CYP3A with a narrow therapeutic window.
