Further study details as provided by Bristol-Myers Squibb:

Primary Outcome Measures:
  • The rate of Complete Cytogenetic Response [ Time Frame: 12 months ]
  • The duration of initial TKI treatment [ Time Frame: 5-years from study index date ]
    Initiation of first-line TKI, (whether Dasatinib, Imatinib, Nilotinib)

  • The rate of discontinuation and treatment changes after initial TKI treatment [ Time Frame: Every 6 months for a follow-up period of 5-years from study index date ]
    Dates of switches in therapy from initial TKI treatment, Reasons for treatment discontinuation (i.e. side effects, mutations, etc.), Subsequent lines of CML treatments (start and stop dates)

  • The rate of best response to therapy (i.e. hematologic, cytogenetic, molecular response) [ Time Frame: Every 6 months for a follow-up period of 5-years from study index date ]
    Results and dates of: all bone marrow aspirates, blood tests, cytogenetics, Polymerase Chain Reaction (PCR), Fluorescent In-Situ Hybridization (FISH), and Physical exam

  • The adherence to treatment [ Time Frame: Every 6 months for a follow-up period of 5-years from study index date ]
    Morisky Medication Adherence Scale - 8 Items is a validated self-reported measure of medication adherence.

Secondary Outcome Measures:
  • Impact of first-line treatment options on quality of life [ Time Frame: Every 6 months ]

    Questionnaires used for assessment:

    Functional Assessment of Cancer Therapy - General (FACT-G), Cancer Therapy Satisfaction Questionnaire (CTSQ), MD Anderson Symptom Inventory - CML (MDASI-CML).

  • Non-hematologic side effects from treatment affecting patient quality of life and outcomes [ Time Frame: Every 6 months ]
    Treatment discontinuations and changes

  • Patient satisfaction with CML treatment [ Time Frame: Every 6 months ]
    Cancer Therapy Satisfaction Questionnaire (CTSQ)

  • Patterns of disease monitoring as observed in a real-world setting [ Time Frame: Every 6 months ]
    MD Anderson Symptom Inventory - CML (MDASI-CML) Questionnaire - disease-specific module of the MDASI7 which is a brief measure of severity and impact of cancer-related symptoms on daily function

  • Resource utilization associated with CML management [ Time Frame: Every 6 months ]
    To evaluate healthcare resource utilization, descriptive statistics will describe real-world disease monitoring patterns, frequency of testing, and resources used for disease management for each treatment cohort.

Enrollment: 1494
Study Start Date: December 2010
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
First line TKI treatment: Imatinib
Diagnosed CML patients who receive first line TKI treatment: Imatinib
First line TKI treatment: Nilotinib
Diagnosed CML patients who receive first line TKI treatment: Nilotinib
First line TKI treatment: Dasatinib
Diagnosed CML patients who receive first line TKI treatment: Dasatinib
Imatinib treated patients
Imatinib treated patients if their study index date is between January 2, 2008 and September 30, 2010

Detailed Description:
Time Perspective : Most patients are expected to be a mix of retrospective and prospective data collection. Patients can be enrolled after their study index date (retrospective component) and have to be followed until 5 years from study index date are complete (time between enrollment and 5 year follow-up is the prospective component)

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients will be recruited at oncology practices or oncology centers linked to a hospital in the North Americas, Europe and potentially at additional sites in South America, and Asia

Inclusion Criteria:

  • Newly-diagnosed chronic phase chronic myeloid leukemia (CP-CML) patients who started their first-line Tyrosine Kinase Inhibitor (TKI) treatment on imatinib, dasatinib or nilotinib in accordance with the timelines below
  • 18 years or older at time of of CP-CML diagnosis

    a) Imatinib Cohorts

  • Patients who started their first-line Imatinib treatment between January 2, 2008 and September 30, 2010.Patients fitting this criterion are defined as retrospective Imatinib patients

    − Patients who started their first-line Imatinib treatment on or after October 1, 2010

    b) Dasatinib Cohort

  • Patients who started their first-line Dasatinib treatment after the drug was approved in this indication

    c) Nilotinib Cohort

  • Patients who started their first-line Nilotinib treatment after the drug was approved in this indication
  • Patients are also eligible when they have already switched to a subsequent therapy (TKI or other) at the time of enrollment, as long as their first-line and subsequent CML treatment information is available at site for data entry into the study Electronic Case Report Form (eCRF)
  • Receiving treatment at medical practice (eg. community-based, office-based, hospital-based, academic setting, oncology center)

Exclusion Criteria:

  • Patients who are participating in an interventional trial which may influence the management of their CML disease will be excluded

Discontinuation Criteria:

  • Enrolled patients who join an interventional trial which may influence the management of their CML disease will be excluded at the time of entry into the interventional trial
