  Purpose
The purpose of this study is to fulfill the post-authorization commitment made by Pfizer to the European Medicines Agency in providing additional safety and efficacy data in approximately 150 Philadelphia Chromosome Positive Chronic Myeloid Leukemia patients with high unmet medical need, including 75 Chronic Phase, Accelerated Phase or Blast Phase patients in the fourth or later line treatment setting (i.e., after treatment with at least 3 other Tyrosine Kinase Inhibitors).

Primary Outcome Measures:
  • Percentage of Participants with Major Cytogenetic Response (MCyR) by Week 52 in Chronic Phase Second-line Population and Chronic Phase Third-line Population of Philadelphia Chromosome Positive Chronic Myeloid Leukemia patients. [ Time Frame: Week 52 ]
    Cytogenetic response (CyR) is based on the prevalence of Philadelphia positive cells in metaphase from Bone Marrow sample.

  • Percentage of Participants with Major Cytogenetic Response (MCyR) by Week 52 in Chronic Phase Fourth-line and later-line Population of Philadelphia Chromosome Positive Chronic Myeloid Leukemia patients. [ Time Frame: Week 52 ]
    Cytogenetic response (CyR) is based on the prevalence of Philadelphia positive cells in metaphase from Bone Marrow sample.

  • Percentage of Participants with Overall Hematologic Response (OHR) by Week 52 in Advanced Leukemia Population patients. [ Time Frame: Week 52 ]
    OHR includes Complete Hematological Response (CHR) or return to chronic phase (RCP).


Secondary Outcome Measures:
  • Estimate cumulative probability of Percentage of Participants with Major Cytogenetic Response in Chronic Phase and Advanced Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Week 52 ]
    Cytogenetic response (CyR) is based on the prevalence of Philadelphia positive cells in metaphase from Bone Marrow sample.

  • Estimate cumulative probability of Percentage of Participants with Overall Hematologic Response in the Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient population by number of lines of prior therapy. [ Time Frame: Week 52 ]
    OHR includes Complete Hematological Response (CHR) or return to chronic phase (RCP).

  • Characterize distribution of best response (molecular, cytogenetic, or hematologic) in the Chronic Phase, Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Week 52 ]
  • Estimating probability of Percentage of Participants with Major Cytogenetic Response at 3, 6, 12, 18, and 24 months in the Chronic Phase, Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Month 3, 6, 12, 18, and 24 ]
  • Estimating the probability of confirmed Overall Hematologic Response at 3, 6, 9, 12, 18, and 24 months in the Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Month 3, 6, 9, 12, 18, and 24 ]
  • Estimating the probability of cumulative confirmed Complete Hematologic Response in the Chronic Phase, Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Week 52 ]
  • Estimating the probability of cumulative major molecular response in the Chronic Phase, Accelerated Phase and Blast Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia patient populations. [ Time Frame: Week 52 ]

Criteria

Inclusion Criteria:

  • Confirmed Philadelphia Chromosome positive Chronic Myeloid Leukemia or Confirmed BCR-ABL1 (Abelson-break point cluster) Positive if Philadelphia Chromosome negative Chronic Myeloid Leukemia (from initial diagnosis).
