Outcome Measures

Primary Outcomes (9)

  • Percentage of Participants With Cumulative Complete Haematological Response (CHR)

    Haematological response used blood sample of the participants to evaluate response to treatment for CML. Based on the European LeukemiaNet (ELN) 2013 definition: CHR is defined as platelet count less than (\<) 450\*10\^9 per liter, white blood cells count \<10\*10\^9 per liter, no immature granulocytes and \<5 percent (%) basophils on differential and a non-palpable spleen.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Partial Haematological Response (PHR)

    Haematological response used blood sample of the participants to evaluate response to treatment for CML.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Complete Cytogenetic Response (CCyR)

    Cytogenetic response (CyR) used bone marrow/blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: CyR was measured by chromosome banding analysis (CBA) or fluorescence in situ hybridisation (FISH). CCyR was indicated by absence of Philadelphia chromosome positive (Ph+) cells metaphases from FISH of blood interphase cell nuclei.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Minor Cytogenetic Response (MCyR)

    CyR used bone marrow/blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: CyR was measured by CBA or FISH. MCyR was indicated by presence of 36-65% Ph+ cells from CBA of bone marrow metaphases.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Minimal Cytogenetic Response (mCyR)

    CyR used bone marrow/blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: CyR was measured by CBA or FISH. mCyR was indicated by presence of 66-95% Ph+ cells from CBA of bone marrow metaphases.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Partial Cytogenetic Response (PCyR)

    CyR used bone marrow/blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: CyR was measured by CBA or FISH. PCyR was indicated by presence of 1-35% Ph+ cells from CBA of bone marrow metaphases.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Complete Molecular Response 4.0 (MR4.0)

    Molecular response used blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: Molecular response used breakpoint cluster region/Abelson (BCR-ABL1) transcript measured by real time quantitative polymerase chain reaction (RT-Q-PCR). Evaluation was expressed as percentage of ratio of BCR-ABL1 transcripts to ABL1 transcripts according to the international scale (IS) or the ratio of BCR/ABL1 transcripts to other internationally recognized control transcripts levels. MR4.0 was defined and recorded as detectable disease with \<0.01% BCR-ABL1 transcripts on IS or undetectable disease in cDNA with greater than (\>) 10,000 ABL1 transcripts in the same volume of cDNA used to test for BCR-ABL1 transcripts.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Complete Molecular Response 4.5 (MR4.5)

    Molecular response used blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: Molecular response used breakpoint cluster region/Abelson (BCR-ABL1) transcript measured by real time quantitative polymerase chain reaction (RT-Q-PCR). Evaluation was expressed as percentage of ratio of BCR-ABL1 transcripts to ABL1 transcripts according to the international scale (IS) or the ratio of BCR/ABL1 transcripts to other internationally recognized control transcripts levels. MR4.5 was defined and recorded as detectable disease with \<0.0032% BCR-ABL1 transcripts on IS or undetectable disease in cDNA with \>32,000 ABL1 transcripts in the same volume of cDNA used to test for BCR-ABL1 transcripts.

    Baseline up to 5.5 years

  • Percentage of Participants With Cumulative Major Molecular Response (MMR)/Molecular Response 3.0 (MR3.0)

    Molecular response used blood sample of the participants to evaluate response to treatment for CML. Based on the ELN 2013 definition: Molecular response used breakpoint cluster region/Abelson (BCR-ABL1) transcript measured by real time quantitative polymerase chain reaction (RT-Q-PCR). Evaluation was expressed as percentage of ratio of BCR-ABL1 transcripts to ABL1 transcripts according to the international scale (IS) or the ratio of BCR/ABL1 transcripts to other internationally recognized control transcripts levels. MMR was defined as a BCR-ABL1 to ABL1 less than or equal to (\<=) 0.1% on the IS.

    Baseline up to 5.5 years

Secondary Outcomes (10)

  • Percentage of Participants With Treatment Related Adverse Events (AEs)

    Baseline up to 5.5 years

  • Percentage of Participants With Treatment Related Adverse Events (AEs) Greater Than or Equal to Grade 3

    Baseline up to 5.5 years

  • Progression-free Survival (PFS)

    Year 1, 2, 3

  • Overall Survival (OS)

    From baseline up to 1 Year, baseline up to Year 2, baseline up to Year 3

  • Percentage of Participants With Disease Progression

    Year 1, 2, 3

  • +5 more secondary outcomes
