Exclusion criteria:

  • Patients in late chronic phase, accelerated phase, or blastic phase are excluded
  • Patients who have received other investigational agents
  • Patients who received imatinib for any duration prior to study entry
  • Patient received any treatment for CML prior to study entry for longer than 2 weeks with the exception of hydroxyurea and/or anagrelide
  • Patients with another primary malignancy except if the other primary malignancy is neither currently clinically significant or requiring active intervention
  • Patients who are:
  • pregnant
  • breast feeding
  • of childbearing potential without a negative pregnancy test prior to baseline
  • male or female of childbearing potential unwilling to use barrier contraceptive precautions throughout the trial
  • Post-menopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential
  • Patient with a severe or uncontrolled medical condition (i.e., uncontrolled diabetes, chronic renal disease)
  • Patient previously received radiotherapy to ≥ 25% of the bone marrow
  • Patient had major surgery within 4 weeks prior to study entry, or who have not recovered from prior major surgery
  • Patients with an ECOG Performance Status Score ≥ 3
  • Patients with International normalized ratio (INR) or partial thromboplastin time (PTT) > 1.5 x IULN, with the exception of patients on treatment with oral anticoagulant
  • Patients with known positivity for human immunodeficiency virus (HIV)
  • baseline testing for HIV is not required
  • Patients with any significant history of non-compliance to medical regimens or with inability to grant a reliable informed consent
  • Patients with identified sibling donors where allogeneic bone marrow transplant is elected as first line treatment
  • Patients who are chronic users of acetaminophen or medications containing acetaminophen.
  • Patients who received acetaminophen or medications containing acetaminophen within 72 hours prior to study entry.
