Eastern Cooperative Oncology Group performance status


  • Age ≥ 18 years
  • Life expectancy of at least 2 months
  • ECOG Performance Status ≤ 2
  • Patients must be able to swallow capsules
  • Adequate hematologic parameters, unless cytopenias are disease caused
  • Adequate renal, liver and cardiac function parameters

The Eastern Cooperative Oncology Group (ECOG) performance status allows patients to be classified as to their functional impairment. Scores run from 0 to 5; the higher the ECOG score, the worse the survival rate for most serious cancers. This score allows physicians to evaluate a patient's ability to survive chemotherapy for cancer.

Exclusion Criteria

  • Patients with GVHD requiring systemic immunosuppressive therapy
  • Uncontrolled leptomeningeal disease, auto-immune hemolytic anemia and uncontrolled and clinical significant disease related metabolic disorder
  • Clinically significant intravascular coagulation
  • Treatment with other investigational drugs within 14 days prior to first study treatment administration
