Outcome Measures

Primary Outcomes (1)

  • The quantification of the risk of progression

    To quantify the risk of progression to accelerated phase (AP) or blast phase (BP), expressed as time adjusted rate (TAR), after TKI discontinuation in CML patients who undergo a first or subsequent TKI discontinuation attempt

    36 Month

Secondary Outcomes (5)

  • To compare the time adjusted rate (TAR) of progression from Chronic phase-Chronic Myeloid Leukemia to Accelerated phase (AP) or Blastic phase (BP) by using the percentage of blasts, promyelocytes, basophils or platelet in blood or bone marrow

    36 Month

  • Progression free survival (PFS) after TKI discontinuation.

    36 Month

  • Rate of molecular relapse (loss of MR3 or MMR)

    36 Month

  • Relapse free survival (RFS) after TKI discontinuation.

    36 Month

  • Percentage of relapsed patients who obtain a new deep molecular response (DMR) within 6-12 months of treatment resumption among all patients who restart TKI treatment because of a molecular relapse after TKI discontinuation.

    36 Month

Study Arms (3)

Retrospective cohort

Patients who discontinued before the opening of this study will contribute to the retrospective cohort.

Prospective cohort

Patients who will discontinue after it will contribute to the prospective cohort.

Retrospective/Prospective cohort

Patients who discontinued before the opening of this study but will continue their discontinuation after it, will contribute to both cohorts.

Sampling MethodProbability Sample
Study Population

The target population will include all CML patients presently eligible for treatment discontinuation independently of whether they discontinued or not. For the time they did not discontinue they will contribute to the reference cohort, while after TD they will contribute data to the discontinuation cohort. In case of treatment resumption, the patient will still contribute to the discontinuation cohort for 36 months after treatment resumption, while he/she will contribute to the reference cohort thereafter, assuming a new TD did not occur.

You may qualify if:

  • Signed and dated IRB/IEC-approved informed consent for the prospective cohort patients.
  • Age \>= 18 years.
  • Male or female patients with CML diagnosed in chronic phase (CP).
  • At least 4 years of TKI treatment.
  • At least 18 months of DMR.

You may not qualify if:

  • Allogeneic hematopoietic stem cell transplantation.
  • CML diagnosed in AP or BC
