Further study details as provided by Kanto CML Study Group:

Primary Outcome Measures:
  • Rate of complete molecular response (CMR) after treatment with dasatinib [ Time Frame: by 18 months ] [ Designated as safety issue: No ]
    The rate(%) of patients who achieve complete molecular response (CMR) by 18 months after the dasatinib therapy will be measured to evaluate the efficiency of dasatinib.

Secondary Outcome Measures:
  • complete molecular response (CMR) [ Time Frame: by 3,6,12,24, 36 months ] [ Designated as safety issue: No ]
  • Major Molecular Response(MMR) [ Time Frame: by 3,6,12,18,24,36 months ] [ Designated as safety issue: No ]
  • Complete Cytogenetic Response(CCyR) [ Time Frame: by 6,12 months ] [ Designated as safety issue: No ]
  • Expansions rate of large granular lymphocyte [ Time Frame: by 12 months ] [ Designated as safety issue: No ]
  • Progression free survival [ Time Frame: at 36 months ] [ Designated as safety issue: No ]
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: by 36 months ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Copy numbers of bcr-abl mRNA in patients with dasatinib treatment will be measured by real-time RT-PCR to evaluate the efficiency of dasatinib.

For patients resistant to dasatinib therapy, DNA mutation analysis of the bcr-abl gene associated with drug-resistancy will be performed.

Estimated Enrollment: 40
