Eligibility Criteria

Inclusion

  • Patients are able to provide written informed consent
  • Patients must have CML in CP which is defined by the presence of all of the following criteria:
  • \< 15% blasts in peripheral blood (PB) and BM.
  • \< 30% blasts plus promyelocytes in PB and BM.
  • \< 20% basophils in the PB.
  • ≥ 100 x 109/L platelets.
  • No evidence of extramedullary leukemia apart from hepatosplenomegaly
  • Ph+ or variants must be demonstrated by BM cytogenetics, FISH or PCR.
  • Previously untreated CML in CP, with the exception of hydroxyurea or anagrelide
  • Patients must be enrolled in this study within 90 days after the date of first being diagnosed with CML
  • ECOG Performance Status (PS) Score 0 - 1 (see Appendix 2)
  • Adequate hepatic function defined as: total bilirubin ≤ 2.0 times the institutional upper limit of normal (ULN) in absence of Gilbert type unconjugated hyperbilirubinemia; alanine aminotransferase (ALAT≤ 2.5 times the institutional ULN.
  • Adequate renal function defined as serum creatinine ≤ 2 times the institutional ULN.
  • Men and women, ages 18 years and older.
  • Adequate BM aspiration sample before the start of study treatment (i.e sample is sufficient for stem cell analysis)
  • Potentially fertile women must use an adequate method of contraception to avoid pregnancy throughout the study.
  • Potentially fertile women must have a negative serum or urine pregnancy test

Exclusion

  • Fertile women who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study
  • Women who are pregnant or breastfeeding.
  • Men with fertile sexual partners who can or will not use an acceptable contraception method for the entire study
  • A serious uncontrolled medical disorder or active infection that would impair the ability of the subject to receive protocol therapy.
  • Known pleural effusion at baseline.
  • Uncontrolled or significant cardiovascular disease
  • History of significant bleeding disorder unrelated to CML, including:
  • Prior chemotherapy for peripheral stem cell mobilization.
  • Inadequate BM aspiration sample due to marrow fibrosis or other reasons
  • Prior or concurrent malignancy
  • Severe psychiatric illness, imprisonment or mental impairment inflicting on ability to give informed consent
  • Abuse of alcohol, prescribed or illicit drugs
  • Evidence of digestive dysfunction that would prevent administration of study therapy by mouth.
  • Prohibited Treatments and/or Therapies
  • Any prior treatment with interferon
  • Any prior treatment with dasatinib
  • Any prior treatment with imatinib
  • Any other prior systemic treatments, with anti-CML activity \[except for anagrelide, or hydroxyurea (HU)\].
  • Patients currently taking drugs that are generally accepted to have a risk of causing Torsades de Pointes as described in Appendix 3.
