- Treatment with chemotherapy or investigational therapy < 4 weeks (28 days) prior to
study entry (6 weeks for nitrosoureas, mitomycin C, or Avastin).

- Treatment with radiation therapy or surgery either within 2 weeks prior to study
entry, or not yet recovered if 2-4 weeks prior to study entry.

- Unwillingness or inability to comply with protocol procedures.

- Known active uncontrolled infection with HIV, hepatitis B, or hepatitis C

- Serious nonmalignant disease (e.g. hydronephrosis, liver failure, or other
conditions) that could compromise protocol objectives in the opinion of the
investigator and/or the sponsor

- Concurrent use of other investigational agent(s)

- Serious concurrent medical illness
