Insights

Bosutinib is now approved in the USA for treating pediatric patients with Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+ CML). This milestone follows its established use in adults with this condition.

Area of Science:

  • Oncology
  • Pharmacology
  • Hematology

Background:

  • Bosutinib (BOSULIF®) is an oral BCR-ABL tyrosine kinase inhibitor (TKI).
  • It is approved in the EU and USA for adult Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) in chronic phase (CP), accelerated phase (AP), and blast phase (BP), both newly diagnosed (ND) and resistant/intolerant (R/I) to prior therapy.

Purpose of the Study:

  • To summarize the development of bosutinib leading to its pediatric approval.
  • To highlight the clinical data supporting bosutinib's use in pediatric Ph+ CML.

Main Methods:

  • Review of clinical development milestones for bosutinib.
  • Analysis of clinical data in pediatric patients aged 1 to <18 years with Ph+ CML.

Main Results:

  • Bosutinib was approved in the USA in September 2023 for pediatric patients aged ≥1 year with ND or R/I CP Ph+ CML.
  • This approval was based on clinical data from pediatric patients.

Conclusions:

  • Bosutinib represents a new treatment option for pediatric patients with Ph+ CML.
  • The drug's development pathway has now extended to include younger patient populations.
