Study title

Bosutinib in Pediatric CML Patients

Scientific title

A Phase I/II Study of Bosutinib in Pediatric Patients with Newly Diagnosed Chronic Phase or Resistant/Intolerant Ph+ Chronic Myeloid Leukemia

Type of study

Pediatric trial



Current status

Active, not recruiting

Other trial ID

AAML1921, COG-ITCC-054, NTR5501, ClinicalTrials.gov NCT04258943, EudraCT no. 2015-002916-34

What is the purpose of the study

This is a study to identify a recommended dose of bosutinib given orally once daily in pediatric patients with newly diagnosed Philadelphia chromosome positive (Ph+) chronic myeloid leukemia in chronic phase (CML-CP) and in pediatric patients with Ph+ CML who have been treated with at least one tyrosine kinase inhibitor (TKI). The study is designed to also estimate the safety, tolerability and efficacy, and to evaluate the pharmacokinetics of bosutinib in this patient population.

What will happen during the study

Bosutinib is given orally once daily at increasing dose levels to determine the recommended dose level for further investigation.



Key inclusion criteria

This study includes patients of all sexes who:

  • are 1 year to 18 years old
  • have newly diagnosed chronic myeloid leukemia (CML) in chronic phase (CP) or who are resistant or intolerant to at least one prior tyrosine kinase inhibitor (TKI).
  • have adequate bone marrow, liver and kidney function
  • have a Lansky performance status of at least 50% for patients up to 16 years of age, or a Karnofsky scale of at least 50% for patients over 16 years of age. Lansky performance status and Karnofsky scale are used to assess to what extent patients are able to carry on normal activities.

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 history of the T315I or V299L BCR-ABL1 mutations at the time of study entry
  • who have received treatment with a TKI within 7 days prior to starting bosutinib treatment, or other antitumor or anti-leukemia treatment within 14 days prior to starting bosutinib treatment (hydoxyurea and/or anagrelide prior to starting bosutinib are allowed)
  • who have undergone allogeneic stem cell transplantation within 3 months prior to bosutinib treatment.
