Key clinical point: Bosutinib was effective and safe as a second or subsequent line of treatment in a real-life cohort of elderly patients with chronic-phase chronic myeloid leukemia (CML-CP) and multiple baseline comorbidities who were resistant or intolerant to previous tyrosine kinase inhibitors (TKIs).
Major finding: Overall, rates of cytogenic response, molecular response, 3-year event-free survival, and 3-year overall survival were 81.2%, 66.6%, 60.9%, and 86.4%, respectively. Grade 3/4 hematological and extra-hematological toxicities were reported in 6.9% and 18.8% of patients, respectively, with 11.9% of patients permanently discontinuing bosutinib because of toxicity.
Study details: Findings are from a retrospective analysis of 101 elderly (age, older than 65 years) patients with CML-CP treated with bosutinib in second or subsequent line. Patients switched to bosutinib because of intolerance (n=46) or resistance (n=55) to previous TKI therapies.
Disclosures: This study did not receive any type of funding. Some investigators including the lead author reported consulting for or receiving honoraria from various pharmaceutical companies.
