Fourth-line bosutinib ‘appropriate’ after prior CML treatment failure, intolerance

In continuation of my update on bosutinib



A Spanish study suggests that bosutinib can help improve or maintain response in patients with chronic myeloid leukaemia (CML) after treatment failure of three previous tyrosine kinase inhibitors (TKI).
Researcher Juan Luís Steegmann (Hospital Universitario de la Princesa, Madrid, Spain) and colleagues analysed medical records of 30 chronic phase CML patients with Philadelphia chromosome-positive disease given bosutinib under the Spanish Compassionate Use programme after discontinuing imatinib, dasatinib and nilotinib as a result of resistance or intolerance.
Of the 15 patients without a complete cytogenetic response at baseline, defined as after TKI use but before bosutinib initiation, two (13.3%) achieved it following bosutinib treatment.
