A phase I/II study of bosutinib in pediatric patients with Chronic Myeloid Leukemia who are resistant or intolerant to at least one prior Tyrosine Kinase Inhibitor therapy (ClinicalTrials.gov NCT04258943; EudraCT no. 2015-002916-34)

Indication and most important inclusion criteria

Pediatric CML patients aged 1 up to 18 years who are resistant (suboptimal response or failure, as defined by 2013 European Leukemia Net guidelines) or intolerant (with or without suboptimal response or failure) to at least one prior tyrosine kinase inhibitor (TKI).

To be included, patients need to have adequate bone marrow, liver and heart function as well as 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.
