Outcome Measures

Primary Outcomes (1)

  • Probability of persistent undetectable molecular residual disease (UMRD) and MR4.5

    Our primary objectives were to evaluate the probability of persistent undetectable molecular residual disease (UMRD) and MR4.5 at 12 months after discontinuation, to measure the duration of persistent UMRD and MR4.5 after discontinuation, and to identify contributing factors for sustained undetectable transcript.

    12 months

Study Arms (1)

Imatinib treatment discontinuing

EXPERIMENTAL
Behavioral: Imatinib treatment discontinuing

Interventions

Ph+ CP CML patients who were treated with IM for more than 3 years in sustained MR4.5 or undetectable transcript for at least 2 years are enrolled

Imatinib treatment discontinuing

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult (≥ 18 years-old) Ph+ CP CML patients who were treated with IM for more than 3 years in sustained MR4.5 or undetectable transcript for at least 2 years are enrolled. MR4.5 or undetectable transcript must be sustained by 2 consecutive RQ-PCR assay within 6 months

You may not qualify if:

  • Patients were diagnosed with AP or BP CML
  • Ph+ ALL
  • Received cytotoxic chemotherapy or any other TKIs except imatinib
  • Any evidence of on-going graft versus-host disease (GVHD)
  • Relapsed patients after allogeneic stem cell transplantation
