Current status


Other trial ID

NCI-2018-03439, U10CA180886, ClinicalTrials.gov NCT03817398

What is the purpose of the study

This is a study to assess how stopping tyrosine kinase inhibitors will affect treatment-free remission in patients with CML in chronic phase.

What will happen during the study

Patients stop taking tyrosine kinase inhibitors within 10 days of enrollment. Patients will be closely monitored for 3 years and treatment outcomes, including quality of life, will be reassessed. Patients who lose their molecular remission (MR) may restart taking their tyrosine kinase inhibitor (TKI) and will also be closely monitored for 3 years.

Key inclusion criteria

This study includes patients of all sexes who:

  • have been diagnosed with chronic phase chronic myeloid leukemia (CP CML) before the age of 18 years
  • have histologic confirmation of CP CML at their original diagnosis
  • are in molecular remission with a BCR-ABL1 level of at least 0.01% as measured using the International Scale (IS) by RQ-PCR for at least 2 consecutive years at the time of enrollment
  • have received their current TKI for at least 3 consecutive years at the time of enrollment.

Further criteria may apply. Please discuss these with your doctor or study staff.

Key exclusion criteria

This study does not include patients with:

  • a known T315I mutation
  • additional clonal chromosomal abnormalities in Philadelphia chromosome (Ph) positive (+) cells at any time before study entry
  • a history of CML in advanced phase (AP) or blast crisis (BC).

Further criteria may apply. Please discuss these with your doctor or study staff.
