Medical Editor: John P. Cunha, DO, FACOEP
Bosulif (bosutinib) is a kinase inhibitor used to treat adult patients with chronic, accelerated, or blast phase Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance or intolerance to prior therapy. Common side effects include diarrhea, nausea, low blood platelet count (thrombocytopenia), vomiting, abdominal pain, rash, anemia, fever, and fatigue.
The recommended dose and schedule of Bosulif is 500 mg orally once daily with food. Bosulif may interact with ketoconazole, rifampin, proton pump inhibitors, St. John's wort, and digoxin. Tell your doctor all medications and supplements you use. Bosulif is not recommended for use during pregnancy. It may harm a fetus. Women should use contraception to prevent pregnancy during and for at least 30 days after completing treatment with Bosulif. Because of potential risk to a nursing infant, breastfeeding is not recommended; consult your doctor.
Our Bosulif (bosutinib) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Bosulif FDA Prescribing Information: Side Effects
The following adverse reactions are discussed in greater detail in other sections of the labeling:
- Gastrointestinal toxicity [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
- Myelosuppression [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
- Hepatic toxicity [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
- Fluid retention [see WARNINGS AND PRECAUTIONS].
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Serious adverse reactions reported include anaphylactic shock [see CONTRAINDICATIONS], myelosuppression, gastrointestinal toxicity (diarrhea), fluid retention, hepatotoxicity and rash.
Adverse reactions of any toxicity grade reported for greater than 20% of patients in the Phase ½ safety population (n=546) were diarrhea (82%), nausea (46%), thrombocytopenia (41%), vomiting (39%), abdominal pain (37%), rash (35%), anemia (27%), pyrexia (26%), and fatigue (24%).
Imatinib-Resistant or -Intolerant Ph+ Chronic Phase (CP), Accelerated Phase (AP), and Blast Phase (BP) CML
The single-arm Phase ½ clinical trial enrolled patients with Ph+ chronic, accelerated, or blast phase chronic myelogenous leukemia (CML) and Ph+ acute lymphoblastic leukemia (ALL) with resistance or intolerance to prior therapy. The safety population (received at least 1 dose of BOSULIF) included 546 CML patients. Within the safety population there were 287 patients with CP CML previously treated with imatinib only who had a median duration of BOSULIF treatment of 24 months, and a median dose intensity of 484 mg/day. There were 119 patients with CP CML previously treated with both imatinib and at least 1 additional TKI who had a median duration of BOSULIF treatment of 9 months and a median dose intensity of 475 mg/day. There were 76 patients with AP CML, and 64 patients with BP CML. In the patients with AP CML and BP CML, the median duration of BOSULIF treatment was 10 months and 3 months, respectively. The median dose intensity was 483 mg/day, and 500 mg/day, in the AP CML and BP CML cohorts, respectively.
Table 2 identifies adverse reactions greater than or equal to 10% for all grades and grades 3 or 4 for the Phase ½ CML safety population.
