`1
`
`
`
` INDICATIONS AND USAGE
`
`
`
`
`
` BOSULIF is indicated for the treatment of adult patients with:
` • Newly-diagnosed chronic phase (CP) Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+
`
`
`
`
` CML).
` • Chronic phase, accelerated phase (AP), or blast phase (BP) Ph+ CML with resistance or intolerance to prior
`
` therapy.

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
` 2.1 Recommended Dosing
`
`
`
`
`
`
` The recommended dose is taken orally once daily with food. The tablet is to be swallowed whole and should not be
`
` broken or cut. Continue treatment with BOSULIF until disease progression or intolerance to therapy.
`
`
`
`
`
`
`
` If a dose is missed beyond 12 hours, the patient should skip the dose and take the usual prescribed dose on the
`
` following day.
`
` Newly-Diagnosed CP Ph+ CML
`
`
`
`
` The recommended dose of BOSULIF is 400 mg orally once daily with food.
`
`
`
`
`
`CP, AP, or BP Ph+ CML with Resistance or Intolerance to Prior Therapy
`
`
`
`The recommended dose and schedule of BOSULIF is 500 mg orally once daily with food.
`
`
`2.2 Dose Escalation
`
`
`
`
`
`In clinical studies of adult Ph+ CML patients, dose escalation by increments of 100 mg once daily to a maximum of
`
`
`
`600 mg once daily was allowed in patients who did not achieve or maintain a hematologic, cytogenetic, or molecular
`
`
`
`response and who did not have Grade 3 or higher adverse reactions at the recommended starting dosage.
`
`
`2.3 Dose Adjustments for Non-Hematologic Adverse Reactions
`
`
`
`
`Elevated liver transaminases: If elevations in liver transaminases greater than 5×institutional upper limit of normal
`
`
`(ULN) occur, withhold BOSULIF until recovery to less than or equal to 2.5×ULN and resume at 400 mg once daily
`
`
`
`
`
`thereafter. If recovery takes longer than 4 weeks, discontinue BOSULIF. If transaminase elevations greater than or equal
`
`
`
`
`to 3×ULN occur concurrently with bilirubin elevations greater than 2×ULN and alkaline phosphatase less than 2×ULN
`
`
`
`(Hy’s law case definition), discontinue BOSULIF [see Warnings and Precautions (5.3)].
`
`
`
`Diarrhea: For National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE)
`
`
`Grade 3-4 diarrhea (increase of greater than or equal to 7 stools/day over baseline/pretreatment), withhold BOSULIF until
`
`
`recovery to Grade less than or equal to 1. BOSULIF may be resumed at 400 mg once daily [see Warnings and
`
`
`
`
`Precautions (5.1)].
`
`For other clinically significant, moderate or severe non-hematological toxicity, withhold BOSULIF until the
`
`
`
`
`toxicity has resolved, then consider resuming BOSULIF at a dose reduced by 100 mg taken once daily. If clinically
`
`
`appropriate, consider re-escalating the dose of BOSULIF to the starting dose taken once daily. Doses less than
`
`
`
`
`
`300 mg/day have been used in patients; however, efficacy has not been established.

`

`
`5 WARNINGS AND PRECAUTIONS
`
`
`
`
`5.1 Gastrointestinal Toxicity
`
`Diarrhea, nausea, vomiting, and abdominal pain occur with BOSULIF treatment. Monitor and manage patients
`
`
`
`using standards of care, including antidiarrheals, antiemetics, and fluid replacement.
`
`In the randomized clinical trial in patients with newly-diagnosed Ph+ CML, the median time to onset for diarrhea
`
`
`
`
`
`(all grades) was 4 days and the median duration per event was 3 days.
`
`
`
`
`Among 546 patients in a single-arm study in patients with CML who were resistant or intolerant to prior therapy,
`
`
`
`
`
`
`
`
`the median time to onset for diarrhea (all grades) was 2 days and the median duration per event was 2 days. Among the
`
`
`
`
`
`
`
`
`
`patients who experienced diarrhea, the median number of episodes of diarrhea per patient during treatment with
`
`
`BOSULIF was 3 (range 1-268).
`
`To manage gastrointestinal toxicity, withhold, dose reduce, or discontinue BOSULIF as necessary [see Dosage and
`
`
`
`Administration (2.3) and Adverse Reactions (6)].
`
`
`
`
`5.2 Myelosuppression
`
`Thrombocytopenia, anemia and neutropenia occur with BOSULIF treatment. Perform complete blood counts
`
`
`weekly for the first month of therapy and then monthly thereafter, or as clinically indicated. To manage
`
`
`
`
`
`myelosuppression, withhold, dose reduce, or discontinue BOSULIF as necessary [see Dosage and Administration (2.4)
`
`
`
`
`and Adverse Reactions (6)].
`
`
`5.3 Hepatic Toxicity
`
`Bosutinib may cause elevations in serum transaminases (alanine aminotransferase [ALT], aspartate
`
`
`
`
`aminotransferase [AST]).
`
`Two cases consistent with drug induced liver injury (defined as concurrent elevations in ALT or AST greater than
`
`
`
`
`or equal to 3×ULN with total bilirubin greater than 2×ULN and alkaline phosphatase less than 2×ULN) have occurred
`
`
`
`
`without alternative causes. This represented 2 out 1711 patients in BOSULIF clinical trials.
`
`
`
`
`
`In the 268 patients from the safety population in the randomized clinical trial in patients with newly-diagnosed
`
`
`
`
`
`CML in the BOSULIF treatment group, the incidence of ALT elevation was 68.3% and AST elevation was 56.0%. Of
`
`
`
`patients who experienced transaminase elevations of any grade, 73% experienced their first event within the first
`
`
`3 months. The median time to onset of increased ALT and AST was 29 and 56 days, respectively, and the median
`
`
`
`
`
`
`
`
`duration was 19 and 15 days, respectively.
`
`
`
`Among the 546 patients in a single-arm study in patients with CML who were resistant or intolerant to prior
`
`
`
`
`therapy, the incidence of ALT elevation was 53.3% and AST elevation was 46.7%. Sixty percent of the patients
`
`
`
`
`
`
`experienced an increase in either ALT or AST. Most cases of transaminase elevations in this study occurred early in
`
`
`
`
`treatment; of patients who experienced transaminase elevations of any grade, more than 81% experienced their first event
`
`
`
`
`
`
`within the first 3 months. The median time to onset of increased ALT and AST was 22 and 29 days, respectively, and the
`
`
`
`
`
`
`median duration for each was 21 days.
`
`Perform hepatic enzyme tests monthly for the first 3 months of BOSULIF treatment and as clinically indicated. In
`
`
`
`
`
`patients with transaminase elevations, monitor liver enzymes more frequently. Withhold, dose reduce, or discontinue
`
`
`
`
`
`BOSULIF as necessary [see Dosage and Administration (2.3) and Adverse Reactions (6)].
`
`
`
`
`
`5.4 Cardiovascular Toxicity
`
`BOSULIF can cause cardiovascular toxicity including cardiac failure, left ventricular dysfunction, and cardiac
`
`
`
`
`
`ischemic events. Cardiac failure events occurred more frequently in previously treated patients than in patients with newly
`
`
`
`diagnosed CML and were more frequent in patients with advanced age or risk factors, including previous medical history
`
`
`
`
`
`
`
`
`of cardiac failure. Cardiac ischemic events occurred in both previously treated patients and in patients with newly
`
`
`
`diagnosed CML and were more common in patients with coronary artery disease risk factors, including history of
`
`
`
`
`diabetes, body mass index greater than 30, hypertension, and vascular disorders.
`
`
`In a randomized study with newly diagnosed CML, cardiac failure occurred in 1.9% of patients treated with
`
`
`
`
`
`
`BOSULIF compared to 0.8% of patients treated with imatinib. Cardiac ischemic events occurred in 4.9% of patients
`
`
`
`treated with BOSULIF compared to 0.8% of patients treated with imatinib.
`
`
`
`In a single-arm study in patients with CML who were resistant or intolerant to prior therapy, cardiac failure was
`
`
`
`
`observed in 5.3% of patients and cardiac ischemic events were observed in 4.9% of patients treated with BOSULIF.

`For current labeling information, please visit https://www.fda.gov/drugsatfda
`
`

`

`
`
`
`
` Monitor patients for signs and symptoms consistent with cardiac failure and cardiac ischemia and treat as clinically
` indicated. Interrupt, dose reduce, or discontinue BOSULIF as necessary [see Dosage and Administration (2.3)].
`
`
`
`
` 5.5 Fluid Retention
`
`
`Fluid retention occurs with BOSULIF and may manifest as pericardial effusion, pleural effusion, pulmonary edema,
`
`
` and/or peripheral edema.
` In the randomized clinical trial of 268 patients with newly-diagnosed CML in the bosutinib treatment group,
`
`
`
`
`
`
`
`
`
` 3 patients (1.1%) experienced severe fluid retention of Grade 3, 1 patient experienced Grade 3 pericardial effusion, and
`
` 2 patients experienced Grade 3 pleural effusion. Among 546 patients in a single-arm study in patients with Ph+ CML who
`
`
`
`
` were resistant or intolerant to prior therapy, Grade 3 or 4 fluid retention was reported in 30 patients (6%). Some patients
`
`
`
`
`
`
`
` experienced more than one fluid retention event. Specifically, 24 patients experienced Grade 3 or 4 pleural effusions,
`
`
`
`
`
` 9 patients experienced Grade 3 or Grade 4 pericardial effusions, and 6 patients experienced Grade 3 edema.
`
`
`
`
`
`
`
` Monitor and manage patients using standards of care. Interrupt, dose reduce or discontinue BOSULIF as necessary
`
`
` [see Dosage and Administration (2.3) and Adverse Reactions (6)].
`
`
`
` 5.6 Renal Toxicity
`
`
` An on-treatment decline in estimated glomerular filtration rate (eGFR) has occurred in patients treated with
`
`
`
`
` BOSULIF. Table 3 identifies the shift from baseline to lowest observed eGFR during BOSULIF therapy for patients in the
` pooled leukemia studies regardless of line of therapy. The median duration of therapy with BOSULIF was approximately
`
`
`
`
` 24 months (range, 0.03 to 155) for patients in these studies.

`
`
`
` Abbreviations: eGFR=estimated glomerular filtration rate; N/n=number of patients.
`
` Notes: eGFR was calculated using Modification in Diet in Renal Disease method (MDRD).
`
`
` Notes: Grading is based on Kidney Disease Improving Global Outcomes (KDIGO) Classification by eGFR: Normal: greater than or
`
`
`
` equal to 90, Mild: 60 to less than 90, Mild to Moderate: 45 to less than 60, Moderate to Severe: 30 to less than 45, Severe: 15 to less
`
` than 30, Kidney Failure: less than 15 ml/min/1.73 m2 .
`
`
`*Among the 1372 patients, eGFR was missing in 7 patients at baseline or on-therapy. There were no patients with kidney failure at
`
`
`
`
`
`
` baseline.
`
`Monitor renal function at baseline and during therapy with BOSULIF, with particular attention to those patients
`
`
`
`
`who have preexisting renal impairment or risk factors for renal dysfunction. Consider dose adjustment in patients with

`
`
`
`
`
`baseline and treatment emergent renal impairment [see Dosage and Administration (2.5)].

`
`5.7 Embryo-Fetal Toxicity
`
`
`
`Based on findings from animal studies and its mechanism of action, BOSULIF can cause fetal harm when
`
`
`
`administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. In
`
`
`
`
`animal reproduction studies conducted in rats and rabbits, oral administration of bosutinib during organogenesis caused
`
`
`adverse developmental outcomes, including structural abnormalities, embryo-fetal mortality, and alterations to growth at
`
`
`
`
`maternal exposures (AUC) as low as 1.2 times the human exposure at the dose of 500 mg/day. Advise pregnant women of
`
`
`
`
`
`the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment and
`
`
`
`
`
`for at least 2 weeks after the last dose [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].

`
`ADVERSE REACTIONS
`
`The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling:

`• Fluid retention [see Warnings and Precautions (5.5)].
`
`
`
`
`• Renal toxicity [see Warnings and Precautions (5.6)].
`
`
`
`
`
`two hundred sixty-eight (268) patients with newly-diagnosed CP CML had a median duration of BOSULIF
`
`treatment of 55 months (range: 0.3 to 60 months) and a median dose intensity of 394 mg/day.
`
`
`
`
`
`
`
`6.1 Clinical Trials Experience
`
`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.
`
`The most common adverse reactions, in ≥20% of patients with newly diagnosed CP Ph+ CML or CP, AP, or BP
`
`
`
`
`
`Ph+ CML with resistance or intolerance to prior therapy (N=814) were diarrhea (80%), rash (44%), nausea (44%),
`
`
`
`
`abdominal pain (43%), vomiting (33%), fatigue (33%), hepatic dysfunction (33%), respiratory tract infection (25%),
`
`
`pyrexia (24%), and headache (21%).
`
`
`The most common laboratory abnormalities that worsened from baseline in ≥20% of patients were creatinine
`
`
`
`
`increased (93%), hemoglobin decreased (90%), lymphocyte count decreased (72%), platelets decreased (69%), ALT

`
`
`
`
`
`daily or imatinib 400 mg daily as single agents (Newly-Diagnosed CP CML Study) [see Clinical Studies (14.1)]. The

`
`
`artery disease (0.4%), cardiac failure acute (0.4%), and renal failure (0.4%).
`
`

`
`
`diagnosed CP CML who received bosutinib. Adverse reactions which resulted in permanent discontinuation in > 2% of
`
`
`
`patients included hepatic dysfunction (9%).
`
`
`
`Dose modifications (dose interruption or reductions) of bosutinib due to an adverse reaction occurred in 68% of
`
`
`
`
`
`patients with newly-diagnosed CP CML. Adverse reactions which required dose interruptions or reductions in >5% of
`
`
`
`patients included hepatic dysfunction (27%), thrombocytopenia (16%), diarrhea (16%), lipase increased (10%),
`neutropenia (7%), abdominal pain (6%), rash (5%).
`

`
`
`
`
`
`were diarrhea (75%), hepatic dysfunction (45%), rash (40%), abdominal pain (39%), nausea (37%), fatigue (33%),
`respiratory tract infection (27%), headache (22%), and vomiting (21%).
`
`
`The most common laboratory abnormalities that worsened from baseline in ≥20% of patients were creatinine
`
`
`
`
`increased (94%), hemoglobin decreased (89%), lymphocyte count decreased (84%), ALT increased (68%), platelet count
