E.4 | Principal exclusion criteria |
1. Patients must not have significant medical illness that in the Investigator’s opinion cannot be adequately controlled with appropriate therapy or would compromise the patient’s ability to tolerate this therapy. 2. <24 days from prior temozolomide, <6 weeks from nitrosourea, <4 weeks from other chemotherapy or investigational agents prior to start of treatment within study. 3.

Known HIV infection; HIV testing is not required. 6. Markedly decreased visual acuity if attributed to other causes than GBM. 7. Active infection requiring parenteral systemic antibiotics. 8. Patients with coagulation problems and medically significant bleeding in the month prior to start of treatment (e.g., peptic ulcer, epistaxis, spontaneous bleeding). Prior history of DVT or PE is not exclusionary. 9. Patients who are pregnant or breast-feeding. 10. Other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission and off all therapy for that disease for a minimum of 3 years. 11. Patients must not have significantly diseased or obstructed gastrointestinal tract, malabsorption, uncontrolled vomiting or diarrhea or inability to swallow oral medications. 12. Dehydration of National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 1. 13. Patients must not have serious psychiatric or medical conditions that could interfere with treatment. 14. History of organ allograft. 15. Concurrent therapy with approved or investigational anticancer therapeutics. 16. Prior treatment with bevacizumab or other direct VEGF/ VEGFR inhibitors. For any question of the definition of a direct VEGF/VEGFR consult Sponsor. 17. Arms C and D only: Body Surface area < 1.2 m2, to avoid a dose exceeding the maximum allowable dose of 70 mg/m2. 18. Major surgery < 4 weeks prior to the start of study treatment. |
