Is this trial a fit for you?
✓Likely a good fit
Adults with Philadelphia chromosome–positive chronic myeloid leukemia who are being treated with or will start bosulif according to local labeling and who can give informed consent are ideal candidates.
✕Probably not a fit
Patients who are contraindicated for bosulif, who decline consent for use of their data, or who are not treated at participating sites are unlikely to benefit from participation.

What this trial studies
This is an observational, post‑marketing program collecting safety and effectiveness information on bosulif when prescribed in routine clinical practice. Eligible adults are those who are being treated with bosulif or who will begin bosulif treatment according to local product labeling, including patients who started within one year before consent. Data are collected during normal clinic visits with informed consent, and patients contraindicated for bosulif or who refuse use of their data are excluded. The study is sponsored by Pfizer and aims to describe real‑world outcomes rather than change assigned treatment.
Why it matters
Potential benefit: If successful, the study could provide real‑world safety and effectiveness data to help doctors and patients make more informed treatment choices with bosulif.
How similar studies have gone: Previous randomized trials and real‑world reports have shown bosutinib (bosulif) can be effective for Philadelphia chromosome–positive CML, so this study is gathering additional routine‑care safety and effectiveness data.
