  • No medical, psychological, familial, sociological, or geographical condition that, in the opinion of the investigator, may preclude the patient's ability to tolerate or complete study treatment, comply with study protocol and follow-up schedule, or give reliable informed consent
  • PRIOR CONCURRENT THERAPY:
  • Recovered from all prior therapy
  • More than 28 days since prior chemotherapy, biologic therapy, or any other investigational drug
  • More than 14 days since prior major surgery
  • No concurrent therapeutic anticoagulation with coumarin derivatives
  • Concurrent therapeutic anticoagulation with low-molecular weight heparin allowed
  • Concurrent mini-dose coumarin derivatives (i.e., equivalent to 1 mg of oral warfarin daily) as prophylaxis allowed
  • No concurrent cytokines (i.e., filgrastim \[G-CSF\] or sargramostim \[GM-CSF\]) to support blood counts
  • No other concurrent investigational drugs
  • No other concurrent anticancer agents, including chemotherapy, radiotherapy, or anticancer biologic therapy
