PHARMACODYNAMICS SECTION.


12.2 Pharmacodynamics. The effect of single dose of bosutinib 500 mg alone and with ketoconazole on the QTc interval was evaluated in randomized, placebo- and active-controlled (moxifloxacin 400 mg) two or three-period crossover thorough QT study in 60 healthy subjects. No significant changes in placebo adjusted, baseline-corrected QTc were observed.

PHARMACOKINETICS SECTION.


12.3 Pharmacokinetics. AbsorptionFollowing administration of single dose of BOSULIF 500 mg with food in patients with cancer, the median time-to-peak concentration (tmax) was 4-6 hours. Bosutinib exhibits dose proportional increases in AUC and Cmax, over the dose range of 200 to 800 mg. After 15 daily doses of BOSULIF (500 mg) with food in patients with CML, the mean (SD) Cmax value was 200 (12) ng/mL, and the mean (SD) AUC was 3650 (425) ngh/mL. When given with high fat meal, the Cmax and AUC of bosutinib increased 1.8- and 1.7-fold, respectively.. DistributionAfter administration of single dose of BOSULIF 500 mg with food in patients with CML, bosutinib had mean apparent volume of distribution +- standard deviation of 6080 +- 1230 L.Bosutinib was highly bound to human plasma proteins in vitro (94%) and ex vivo in healthy subjects (96%), and binding was not concentration-dependent. Bosutinib is P-gp substrate and inhibitor in vitro. No studies have been conducted with other transporters. MetabolismBosutinib is primarily metabolized by CYP3A4. The major circulating metabolites identified in plasma are oxydechlorinated (M2) bosutinib (19% of parent exposure) and N-desmethylated (M5) bosutinib (25% of parent exposure), with bosutinib N-oxide (M6) as minor circulating metabolite. All the metabolites were deemed inactive. EliminationIn patients with CML given single oral doses of BOSULIF 500 mg with food, the mean terminal phase elimination half-life (t1/2) was 22.5 (1.7) hours, and the mean (SD) clearance (Cl/F) was 189 (48) L/h. In six healthy male subjects given single oral dose of [14C] radiolabeled bosutinib, 91.3% of the dose was recovered in feces and 3% of the dose recovered in urine. Hepatic ImpairmentIn dedicated hepatic impairment trial, single dose of BOSULIF 200 mg was administered with food to 18 volunteers with hepatic impairment (Child-Pugh classes A, B, and C) and matched healthy volunteers. Cmax of bosutinib increased 2.4-fold, 2-fold, and 1.5-fold, respectively, in Child-Pugh classes A, B, and C, and bosutinib AUC increased 2.3-fold, 2-fold, and 1.9-fold, respectively [see Dosage and Administration (2.7), and Use in Specific Populations (8.6)]. Renal ImpairmentIn dedicated renal impairment trial, single dose of BOSULIF 200 mg was administered with food to 26 subjects with mild (CLcr: 51 to 80 mL/min), moderate (CLcr: 30 to 50 mL/min) or severe renal impairment (CLcr less than 30 mL/min) and to subjects with normal renal function. Creatinine Clearance for category classification was calculated by the Cockcroft-Gault formula. Subjects with moderate and severe renal impairment had 35% and 60% increase in AUC compared to subjects with normal renal function, respectively. Bosutinib exposure was not changed in subjects with mild renal impairment. The BOSULIF dose should be reduced in patients with severe (CLcr less than 30 mL/min) or moderate (CLcr between 30 to 50 mL/min) renal impairment [see Dosage and Administration (2.1) and Use in Specific Populations (8.7)]. Drug Interactions. CYP3A InhibitorsIn cross-over trial of 24 healthy volunteers, single dose of 100 mg of BOSULIF was either administered alone or in combination with five daily doses of 400 mg of ketoconazole under fasting conditions. Ketoconazole increased bosutinib Cmax and AUC 5.2-fold and 8.6-fold, respectively [see Dosage and Administration (2.5) and Drug Interactions (7.1)]. CYP3A InducersIn cross-over trial of 24 healthy volunteers, single dose of 500 mg of BOSULIF was either administered alone or in combination with six daily doses of 600 mg of rifampin under fed conditions. Rifampin decreased bosutinib Cmax and AUC by 86% and 94%, respectively [see Dosage and Administration (2.5) and Drug Interactions (7.2)]. P-gp SubstratesAn in vitro study suggests that BOSULIF has the potential to increase the plasma concentrations of drugs that are P-gp substrates. The estimated I/IC50 was 0.19, when considering the Cmax at the 500 mg dose of BOSULIF. pH Altering MedicationsBOSULIF displays pH-dependent aqueous solubility, in vitro. In cross-over trial in 24 healthy volunteers, single oral dose of 400 mg of BOSULIF was either administered alone or in combination with multiple-oral doses of 60 mg of lansoprazole under fasting conditions. Lansoprazole decreased bosutinib Cmax and AUC by 46% and 26%, respectively.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. 2-year carcinogenicity study was conducted orally in rats at bosutinib doses up to 25 mg/kg/day in males and 15 mg/kg/day in females. The exposures achieved at the high dose were approximately 1.5- to 3-fold the human exposure (based on AUC) at the bosutinib dose of 500 mg/day. The study was negative for carcinogenic findings. Bosutinib was not mutagenic or clastogenic in battery of tests, including the bacteria reverse mutation assay (Ames Test), the in vitro assay using human peripheral blood lymphocytes and the micronucleus test in orally treated male mice.In rat fertility study, drug-treated males were mated with untreated females, or untreated males were mated with drug-treated females. Females were administered the drug from pre-mating through early embryonic development. The dose of 70 mg/kg/day of bosutinib resulted in reduced fertility in males as demonstrated by 16% reduction in the number of pregnancies. There were no lesions in the male reproductive organs at this dose. This dose of 70 mg/kg/day resulted in exposure (AUC) in male rats approximately equal to that in humans at the 500 mg/day dose of bosutinib. Fertility (number of pregnancies) was not affected when female rats were treated with bosutinib. However, there were increased embryonic resorptions at greater than or equal to 10 mg/kg/day of bosutinib (40% of the human exposure), and decreased implantations and reduced number of viable embryos at 30 mg/kg/day of bosutinib (1.4 times the human exposure).

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Bosutinib is tyrosine kinase inhibitor. Bosutinib inhibits the Bcr-Abl kinase that promotes CML; it is also an inhibitor of Src-family kinases including Src, Lyn, and Hck. Bosutinib inhibited 16 of 18 imatinib-resistant forms of Bcr-Abl expressed in murine myeloid cell lines. Bosutinib did not inhibit the T315I and V299L mutant cells. In mice, treatment with bosutinib reduced the size of CML tumors relative to controls and inhibited growth of murine myeloid tumors expressing several imatinib-resistant forms of Bcr-Abl. 12.2 Pharmacodynamics. The effect of single dose of bosutinib 500 mg alone and with ketoconazole on the QTc interval was evaluated in randomized, placebo- and active-controlled (moxifloxacin 400 mg) two or three-period crossover thorough QT study in 60 healthy subjects. No significant changes in placebo adjusted, baseline-corrected QTc were observed. 12.3 Pharmacokinetics. AbsorptionFollowing administration of single dose of BOSULIF 500 mg with food in patients with cancer, the median time-to-peak concentration (tmax) was 4-6 hours. Bosutinib exhibits dose proportional increases in AUC and Cmax, over the dose range of 200 to 800 mg. After 15 daily doses of BOSULIF (500 mg) with food in patients with CML, the mean (SD) Cmax value was 200 (12) ng/mL, and the mean (SD) AUC was 3650 (425) ngh/mL. When given with high fat meal, the Cmax and AUC of bosutinib increased 1.8- and 1.7-fold, respectively.. DistributionAfter administration of single dose of BOSULIF 500 mg with food in patients with CML, bosutinib had mean apparent volume of distribution +- standard deviation of 6080 +- 1230 L.Bosutinib was highly bound to human plasma proteins in vitro (94%) and ex vivo in healthy subjects (96%), and binding was not concentration-dependent. Bosutinib is P-gp substrate and inhibitor in vitro. No studies have been conducted with other transporters. MetabolismBosutinib is primarily metabolized by CYP3A4. The major circulating metabolites identified in plasma are oxydechlorinated (M2) bosutinib (19% of parent exposure) and N-desmethylated (M5) bosutinib (25% of parent exposure), with bosutinib N-oxide (M6) as minor circulating metabolite. All the metabolites were deemed inactive. EliminationIn patients with CML given single oral doses of BOSULIF 500 mg with food, the mean terminal phase elimination half-life (t1/2) was 22.5 (1.7) hours, and the mean (SD) clearance (Cl/F) was 189 (48) L/h. In six healthy male subjects given single oral dose of [14C] radiolabeled bosutinib, 91.3% of the dose was recovered in feces and 3% of the dose recovered in urine. Hepatic ImpairmentIn dedicated hepatic impairment trial, single dose of BOSULIF 200 mg was administered with food to 18 volunteers with hepatic impairment (Child-Pugh classes A, B, and C) and matched healthy volunteers. Cmax of bosutinib increased 2.4-fold, 2-fold, and 1.5-fold, respectively, in Child-Pugh classes A, B, and C, and bosutinib AUC increased 2.3-fold, 2-fold, and 1.9-fold, respectively [see Dosage and Administration (2.7), and Use in Specific Populations (8.6)]. Renal ImpairmentIn dedicated renal impairment trial, single dose of BOSULIF 200 mg was administered with food to 26 subjects with mild (CLcr: 51 to 80 mL/min), moderate (CLcr: 30 to 50 mL/min) or severe renal impairment (CLcr less than 30 mL/min) and to subjects with normal renal function. Creatinine Clearance for category classification was calculated by the Cockcroft-Gault formula. Subjects with moderate and severe renal impairment had 35% and 60% increase in AUC compared to subjects with normal renal function, respectively. Bosutinib exposure was not changed in subjects with mild renal impairment. The BOSULIF dose should be reduced in patients with severe (CLcr less than 30 mL/min) or moderate (CLcr between 30 to 50 mL/min) renal impairment [see Dosage and Administration (2.1) and Use in Specific Populations (8.7)]. Drug Interactions. CYP3A InhibitorsIn cross-over trial of 24 healthy volunteers, single dose of 100 mg of BOSULIF was either administered alone or in combination with five daily doses of 400 mg of ketoconazole under fasting conditions. Ketoconazole increased bosutinib Cmax and AUC 5.2-fold and 8.6-fold, respectively [see Dosage and Administration (2.5) and Drug Interactions (7.1)]. CYP3A InducersIn cross-over trial of 24 healthy volunteers, single dose of 500 mg of BOSULIF was either administered alone or in combination with six daily doses of 600 mg of rifampin under fed conditions. Rifampin decreased bosutinib Cmax and AUC by 86% and 94%, respectively [see Dosage and Administration (2.5) and Drug Interactions (7.2)]. P-gp SubstratesAn in vitro study suggests that BOSULIF has the potential to increase the plasma concentrations of drugs that are P-gp substrates. The estimated I/IC50 was 0.19, when considering the Cmax at the 500 mg dose of BOSULIF. pH Altering MedicationsBOSULIF displays pH-dependent aqueous solubility, in vitro. In cross-over trial in 24 healthy volunteers, single oral dose of 400 mg of BOSULIF was either administered alone or in combination with multiple-oral doses of 60 mg of lansoprazole under fasting conditions. Lansoprazole decreased bosutinib Cmax and AUC by 46% and 26%, respectively.

CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. Imatinib-Resistant or -Intolerant Ph+ Chronic Phase (CP), Accelerated Phase (AP) and Blast Phase (BP) CMLA single-arm, Phase 1/2 open-label, multicenter trial (Study 1) was conducted to evaluate the efficacy and safety of BOSULIF 500 mg once daily in patients with imatinib-resistant or -intolerant CML with separate cohorts for chronic, accelerated, and blast phase disease previously treated with one prior TKI (imatinib) or more than one TKI (imatinib followed by dasatinib and/or nilotinib). The definition of imatinib resistance included (1) failure to achieve or maintain any hematologic improvement within four weeks; (2) failure to achieve complete hematologic response (CHR) by months, cytogenetic response by months or major cytogenetic response (MCyR) by 12 months; (3) progression of disease after previous cytogenetic or hematologic response; or (4) presence of genetic mutation in the BCR-Abl gene associated with imatinib resistance. Imatinib intolerance was defined as inability to tolerate imatinib due to toxicity, or progression on imatinib and inability to receive higher dose due to toxicity. The definitions of resistance and intolerance to both dasatinib and nilotinib were similar to those for imatinib. The protocol was amended to exclude patients with known history of the T315I mutation after 396 patients were enrolled in the trial.The efficacy endpoints for patients with CP CML previously treated with one prior TKI (imatinib) were the rate of attaining MCyR at week 24 and the duration of MCyR. The efficacy endpoints for patients with CP CML previously treated with both imatinib and at least additional TKI were the cumulative rate of attaining MCyR by week 24 and the duration of MCyR. The efficacy endpoints for patients with previously treated AP and BP CML were confirmed complete hematologic response (CHR) and overall hematologic response (OHR).The trial enrolled 546 patients with CP, AP or BP CML. Of the total patient population 73% were imatinib resistant and 27% were imatinib intolerant. In this trial, 53% of patients were males, 65% were Caucasian, and 20% were 65 years old or older. Of the 546 treated patients, 503 were considered evaluable for efficacy. Patients were evaluable for efficacy if they had received at least one dose of BOSULIF and had valid baseline efficacy assessment. Among evaluable patients, there were 266 patients with CP CML previously treated with one prior TKI (imatinib), 108 patients with CP CML previously treated with both imatinib and at least additional TKI, and 129 patients with advanced phase CML previously treated with at least one TKI. Median duration of BOSULIF treatment was 22 months in patients with CP CML previously treated with one TKI (imatinib), months in patients with CP CML previously treated with imatinib and at least additional TKI, 10 months in patients with AP CML previously treated with at least imatinib, and months in patients with BP CML previously treated with at least imatinib.

If dose is missed beyond 12 hours, the patient should skip the dose and take the usual prescribed dose on the following day.. 2.2 Dose Escalation Consider dose escalation to 600 mg once daily with food in patients who do not reach complete hematological response (CHR) by week or complete cytogenetic response (CCyR) by week 12, who did not have Grade or higher adverse reactions, and who are currently taking 500 mg daily. 2.3 Dose Adjustments for Non-Hematologic Adverse Reactions. Elevated liver transaminases: If elevations in liver transaminases greater than 5xinstitutional upper limit of normal (ULN) occur, withhold BOSULIF until recovery to less than or equal to 2.5xULN and resume at 400 mg once daily thereafter. If recovery takes longer than weeks, discontinue BOSULIF. If transaminase elevations greater than or equal to 3xULN occur concurrently with bilirubin elevations greater than 2xULN and alkaline phosphatase less than 2xULN (Hys law case definition), discontinue BOSULIF [see Warnings and Precautions (5.3)].Diarrhea: For NCI CTCAE Grade 3-4 diarrhea (increase of greater than or equal to 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 400 mg once daily. If clinically appropriate, consider re-escalating the dose of BOSULIF to 500 mg once daily. 2.4 Dose Adjustments for Myelosuppression. Dose reductions for severe or persistent neutropenia and thrombocytopenia are described below (Table 1). Table 1: Dose Adjustments for Neutropenia and ThrombocytopeniaANCAbsolute Neutrophil Count less than 1000x106/LWithhold BOSULIF until ANC greater than or equal to1000x106/L and platelets greater than or equal to 50,000x106/L.orPlatelets less than 50,000x106/LResume treatment with BOSULIF at the same dose if recovery occurs within weeks. If blood counts remain low for greater than weeks, upon recovery, reduce dose by 100 mg and resume treatment.If cytopenia recurs, reduce dose by an additional 100 mg upon recovery and resume treatment.Doses less than 300 mg/day have not been evaluated.. 2.5 Concomitant Use With CYP3A Inhibitors. Avoid the concomitant use of strong or moderate CYP3A and/or P-gp inhibitors with BOSULIF as an increase in bosutinib plasma concentration is expected (strong CYP3A inhibitors include ritonavir, indinavir, nelfinavir, saquinavir, ketoconazole, boceprevir, telaprevir, itraconazole, voriconazole, posaconazole, clarithromycin, telithromycin, nefazodone and conivaptan. Moderate CYP3A inhibitors include fluconazole, darunavir, erythromycin, diltiazem, atazanavir, aprepitant, amprenavir, fosamprevir, crizotinib, imatinib, verapamil, grapefruit products and ciprofloxacin) [see Drug Interactions (7.1)]. 2.6 Concomitant Use With CYP3A Inducers. Avoid the concomitant use of strong or moderate CYP3A inducers with BOSULIF as large reduction in exposure is expected (strong CYP3A inducers include rifampin, phenytoin, carbamazepine, St. Johns Wort, rifabutin and phenobarbital. Moderate CYP3A inducers include bosentan, nafcillin, efavirenz, modafinil and etravirine) [see Drug Interactions (7.2)]. 2.7 Recommended Starting Dosage with Hepatic Impairment or Renal Impairment.

3 DOSAGE FORMS AND STRENGTHS. 100 mg tablets: yellow, oval, biconvex, film-coated tablets debossed with Pfizer on one side and 100 on the other. 500 mg tablets: red, oval, biconvex, film-coated tablets debossed with Pfizer on one side and 500 on the other. Tablets: 100 mg and 500 mg. (3).

DRUG INTERACTIONS SECTION.


7 DRUG INTERACTIONS. CYP3A Inhibitors and Inducers: Avoid concurrent use of BOSULIF with strong or moderate CYP3A inhibitors and inducers. (2.5, 2.6, 7.1, 7.2)Proton Pump Inhibitors: May decrease bosutinib drug levels. Consider short-acting antacids in place of proton pump inhibitors. (7.2). CYP3A Inhibitors and Inducers: Avoid concurrent use of BOSULIF with strong or moderate CYP3A inhibitors and inducers. (2.5, 2.6, 7.1, 7.2). Proton Pump Inhibitors: May decrease bosutinib drug levels. Consider short-acting antacids in place of proton pump inhibitors. (7.2). 7.1 Drugs That May Increase Bosutinib Plasma Concentrations. CYP3A or P-glycoprotein (P-gp) inhibitors: Avoid the concomitant use of strong or moderate CYP3A and/or P-gp inhibitors with BOSULIF as an increase in bosutinib plasma concentration is expected [see Dosage and Administration (2.5)]. In dedicated cross-over drug-interaction trial in healthy volunteers (N=24), concomitant ketoconazole (strong CYP3A inhibitor) increased bosutinib Cmax 5.2-fold and AUC 8.6-fold compared to BOSULIF alone [see Clinical Pharmacology (12.3)].. 7.2 Drugs That May Decrease Bosutinib Plasma Concentrations. CYP3A Inducers: Avoid the concomitant use of strong or moderate CYP3A inducers with BOSULIF as large reduction in exposure is expected [see Dosage and Administration (2.6)]. In dedicated cross-over drug-interaction trial in healthy volunteers (N=24), concomitant rifampin (strong CYP3A inducer) decreased bosutinib Cmax by 86% and AUC by 94% compared to BOSULIF alone [see Clinical Pharmacology (12.3)].. Proton Pump Inhibitors: In dedicated cross-over drug-interaction trial in healthy volunteers (N=24), concomitant lansoprazole (PPI) decreased bosutinib Cmax by 46% and AUC by 26% compared to BOSULIF alone [see Clinical Pharmacology (12.3)]. Consider using short-acting antacids or H2 blockers instead of PPIs to avoid reduction in bosutinib exposure. Separate antacid or H2 blocker dosing and BOSULIF dosing by more than hours.. 7.3 Drugs That May Have Their Plasma Concentrations Altered By Bosutinib. Substrates of P-glycoprotein: An in vitro study suggests that BOSULIF may have the potential to increase the plasma concentrations of drugs that are P-gp substrates, such as digoxin [see Clinical Pharmacology (12.3)].

GERIATRIC USE SECTION.


8.5 Geriatric Use. In the Phase 1/2 clinical trial of BOSULIF in patients with Ph+ CML, 20% were age 65 and over, 4% were 75 and over. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

INFORMATION FOR PATIENTS SECTION.


17 PATIENT COUNSELING INFORMATION. See FDA-approved patient labeling (Patient Information).. Dosing and Administration Instruct patients to take BOSULIF exactly as prescribed, not to change their dose or to stop taking BOSULIF unless they are told to do so by their doctor. If patients miss dose beyond 12 hours, they should be advised to take the next scheduled dose at its regular time. double dose should not be taken to make up for any missed dose. Advise patients to take BOSULIF with food. Patients should be advised: Do not crush or cut tablet. Do not touch or handle crushed or broken tablets.. Gastrointestinal Problems Advise patients that they may experience diarrhea, nausea, vomiting, abdominal pain, or blood in their stools with BOSULIF and to seek medical attention promptly for these symptoms.. Low Blood Cell Counts Advise patients of the possibility of developing low blood cell counts and to immediately report fever, any suggestion of infection, or signs or symptoms suggestive of bleeding or easy bruising.. Liver Problems Advise patients of the possibility of developing liver function abnormalities and to immediately report jaundice. o Fluid Retention Advise patients of the possibility of developing fluid retention (swelling, weight gain, or shortness of breath) and to seek medical attention promptly if these symptoms arise.. Renal Problems Advise patients of the possibility of developing renal problems and to immediately report frequent urination, polyuria or oliguria o Other Adverse Reactions Advise patients that they may experience other adverse reactions such as respiratory tract infections, rash, fatigue, loss of appetite, headache, dizziness, back pain, arthralgia, or pruritus with BOSULIF and to seek medical attention if symptoms are significant. There is possibility of anaphylactic shock.. Pregnancy and Breast-feeding Advise patients that BOSULIF can cause fetal harm when administered to pregnant woman. Advise women of the potential hazard to the fetus and to avoid becoming pregnant. If BOSULIF is used during pregnancy, or if the patient becomes pregnant while taking BOSULIF, the patient should be apprised of the potential hazard to the fetus. Because potential risk to the nursing infant cannot be excluded, women that are taking BOSULIF should not breast-feed or provide breast milk to infants.Counsel females of reproductive potential to use effective contraceptive measures to prevent pregnancy during and for at least 30 days after completing treatment with BOSULIF. Instruct patients to contact their physicians immediately if they become pregnant during treatment. Advise patients not to take BOSULIF treatment while pregnant or breastfeeding. If patient wishes to restart breastfeeding after treatment, advise her to discuss the appropriate timing with her physician.. Drug Interactions Advise patients that BOSULIF and certain other medicines, including over the counter medications or herbal supplements (such as St. Johns wort) can interact with each other and may alter the effects of BOSULIF [see Dosage and Administration (2.5) and Drug Interactions (7)]. LAB-0443-4.0. Logo.

MECHANISM OF ACTION SECTION.


12.1 Mechanism of Action. Bosutinib is tyrosine kinase inhibitor. Bosutinib inhibits the Bcr-Abl kinase that promotes CML; it is also an inhibitor of Src-family kinases including Src, Lyn, and Hck. Bosutinib inhibited 16 of 18 imatinib-resistant forms of Bcr-Abl expressed in murine myeloid cell lines. Bosutinib did not inhibit the T315I and V299L mutant cells. In mice, treatment with bosutinib reduced the size of CML tumors relative to controls and inhibited growth of murine myeloid tumors expressing several imatinib-resistant forms of Bcr-Abl.

NONCLINICAL TOXICOLOGY SECTION.


13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. 2-year carcinogenicity study was conducted orally in rats at bosutinib doses up to 25 mg/kg/day in males and 15 mg/kg/day in females. The exposures achieved at the high dose were approximately 1.5- to 3-fold the human exposure (based on AUC) at the bosutinib dose of 500 mg/day. The study was negative for carcinogenic findings. Bosutinib was not mutagenic or clastogenic in battery of tests, including the bacteria reverse mutation assay (Ames Test), the in vitro assay using human peripheral blood lymphocytes and the micronucleus test in orally treated male mice.In rat fertility study, drug-treated males were mated with untreated females, or untreated males were mated with drug-treated females. Females were administered the drug from pre-mating through early embryonic development. The dose of 70 mg/kg/day of bosutinib resulted in reduced fertility in males as demonstrated by 16% reduction in the number of pregnancies. There were no lesions in the male reproductive organs at this dose. This dose of 70 mg/kg/day resulted in exposure (AUC) in male rats approximately equal to that in humans at the 500 mg/day dose of bosutinib. Fertility (number of pregnancies) was not affected when female rats were treated with bosutinib. However, there were increased embryonic resorptions at greater than or equal to 10 mg/kg/day of bosutinib (40% of the human exposure), and decreased implantations and reduced number of viable embryos at 30 mg/kg/day of bosutinib (1.4 times the human exposure).

NURSING MOTHERS SECTION.


8.3 Nursing Mothers. It is not known whether bosutinib is excreted in human milk. Bosutinib and/or its metabolites were excreted in the milk of lactating rats. Radioactivity was present in the plasma of suckling offspring 24 to 48 hours after lactating rats received single oral dose of radioactive bosutinib. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from BOSULIF, decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

OVERDOSAGE SECTION.


10 OVERDOSAGE. Experience with BOSULIF overdose in clinical studies was limited to isolated cases. There were no reports of any serious adverse events associated with the overdoses. Patients who take an overdose of BOSULIF should be observed and given appropriate supportive treatment.

PEDIATRIC USE SECTION.


8.4 Pediatric Use. The safety and efficacy of BOSULIF in patients less than 18 years of age have not been established.

PREGNANCY SECTION.


8.1 Pregnancy. Pregnancy Category [see Warnings and Precautions (5.6)]Based on its mechanism of action and findings in animals, BOSULIF can cause fetal harm when administered to pregnant woman. Studies in animals showed reproductive toxicities. If BOSULIF is used during pregnancy, or if the patient becomes pregnant while taking BOSULIF, the patient should be apprised of the potential hazard to the fetus. Fetal exposure to bosutinib-derived radioactivity during pregnancy was demonstrated in placental-transfer study in pregnant rats. Bosutinib was administered orally to pregnant rats during the period of organogenesis at doses of 1, and 10 mg/kg/day. This study did not expose pregnant rats to enough bosutinib to fully evaluate adverse outcomes. In study conducted in rabbits, bosutinib was administered orally to pregnant animals during the period of organogenesis at doses of 3, 10 and 30 mg/kg/day. At the maternally-toxic dose of 30 mg/kg/day of bosutinib, there were fetal anomalies (fused sternebrae, and two fetuses had various visceral observations), and an approximate 6% decrease in fetal body weight. The dose of 30 mg/kg/day resulted in exposures (AUC) approximately times those in humans at the 500 mg/day dose of bosutinib.

SPL UNCLASSIFIED SECTION.


2.1 Recommended Dosing The recommended dose and schedule of BOSULIF is 500 mg orally once daily with food. Continue treatment with BOSULIF until disease progression or patient intolerance. If dose is missed beyond 12 hours, the patient should skip the dose and take the usual prescribed dose on the following day.

STORAGE AND HANDLING SECTION.


16.2 Storage. Store at 20C to 25C (68F to 77F); excursions permitted to 15C to 30C (59F to 86F) [see USP Controlled Room Temperature].

TERATOGENIC EFFECTS SECTION.


Pregnancy Category [see Warnings and Precautions (5.6)]Based on its mechanism of action and findings in animals, BOSULIF can cause fetal harm when administered to pregnant woman. Studies in animals showed reproductive toxicities. If BOSULIF is used during pregnancy, or if the patient becomes pregnant while taking BOSULIF, the patient should be apprised of the potential hazard to the fetus. Fetal exposure to bosutinib-derived radioactivity during pregnancy was demonstrated in placental-transfer study in pregnant rats. Bosutinib was administered orally to pregnant rats during the period of organogenesis at doses of 1, and 10 mg/kg/day. This study did not expose pregnant rats to enough bosutinib to fully evaluate adverse outcomes. In study conducted in rabbits, bosutinib was administered orally to pregnant animals during the period of organogenesis at doses of 3, 10 and 30 mg/kg/day. At the maternally-toxic dose of 30 mg/kg/day of bosutinib, there were fetal anomalies (fused sternebrae, and two fetuses had various visceral observations), and an approximate 6% decrease in fetal body weight. The dose of 30 mg/kg/day resulted in exposures (AUC) approximately times those in humans at the 500 mg/day dose of bosutinib.

The dose of 30 mg/kg/day resulted in exposures (AUC) approximately times those in humans at the 500 mg/day dose of bosutinib. 8.3 Nursing Mothers. It is not known whether bosutinib is excreted in human milk. Bosutinib and/or its metabolites were excreted in the milk of lactating rats. Radioactivity was present in the plasma of suckling offspring 24 to 48 hours after lactating rats received single oral dose of radioactive bosutinib. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from BOSULIF, decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. 8.4 Pediatric Use. The safety and efficacy of BOSULIF in patients less than 18 years of age have not been established.. 8.5 Geriatric Use. In the Phase 1/2 clinical trial of BOSULIF in patients with Ph+ CML, 20% were age 65 and over, 4% were 75 and over. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.. 8.6 Hepatic Impairment Treat with dose of 200 mg daily in patients with any baseline hepatic impairment. In dedicated hepatic impairment trial, the exposure to bosutinib increased (Cmax increased 1.5- to 2.3-fold and the AUC increased 1.9- to 2.4-fold) in patients with hepatic impairment (Child-Pugh classes A, B, and C; N=18) compared to matched healthy volunteers (N=9) [see Dosage and Administration (2.7), Adverse Reactions (6), and Clinical Pharmacology (12.3)]. 8.7 Renal Impairment Reduce the BOSULIF starting dose in patients with severe (CLcr less than 30 mL/min) or moderate (CLcr 30 to 50 mL/min) renal impairment at baseline. For patients who have declining renal function while on BOSULIF who cannot tolerate 500 mg dose, follow dose adjustment recommendations for toxicity. In dedicated renal impairment trial, compared to subjects with normal renal function, the exposure (AUC) of bosutinib increased by 60% and 35% in subjects with CLcr less than 30 mL/min and CLcr 30 to 50 mL/min, respectively, compared to subjects with normal renal function [see Dosing and Administration (2.7) and Clinical Pharmacology (12.3)]. BOSULIF has not been studied in patients undergoing hemodialysis.

Females of reproductive potential should avoid becoming pregnant while being treated with BOSULIF. (5.6). Gastrointestinal Toxicity: Monitor and manage as necessary. Withhold, dose reduce, or discontinue BOSULIF. (2.3, 5.1). Myelosuppression: Monitor blood counts and manage as necessary. (2.4, 5.2). Hepatic Toxicity: Monitor liver enzymes at least monthly for the first three months and as needed. Withhold, dose reduce, or discontinue BOSULIF. (2.3, 5.3). Fluid Retention: Monitor patients and manage using standard of care treatment. Withhold, dose reduce, or discontinue BOSULIF. (2.3, 5.4). Renal Toxicity Monitor patients for renal function at baseline and during therapy with BOSULIF (5.5). Embryofetal Toxicity: May cause fetal harm. Females of reproductive potential should avoid becoming pregnant while being treated with BOSULIF. (5.6). 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 single-arm Phase 1/2 clinical trial, the median time to onset for diarrhea (all grades) was days and the median duration per event was day. Among the patients who experienced diarrhea, the median number of episodes of diarrhea per patient during treatment with BOSULIF was (range 1-221). 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 One case consistent with drug induced liver injury (defined as concurrent elevations in ALT or AST greater than or equal to 3xULN with total bilirubin greater than 2xULN and alkaline phosphatase less than 2xULN) occurred in trial of BOSULIF in combination with letrozole. The patient recovered fully following discontinuation of BOSULIF. This case represented out of 1209 patients in BOSULIF clinical trials. In the 546 patients from the safety population, the incidence of ALT elevation was 17% and AST elevation was 14%. Twenty percent of the patients experienced an increase in either ALT or AST. Most cases of transaminase elevations occurred early in treatment; of patients who experienced transaminase elevations of any grade, more than 80% experienced their first event within the first months. The median time to onset of increased ALT and AST was 30 and 33 days, respectively, and the median duration for each was 21 days.Perform hepatic enzyme tests monthly for the first three 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 Fluid Retention. Fluid retention occurs with BOSULIF and may manifest as pericardial effusion, pleural effusion, pulmonary edema, and/or peripheral edema.In the single-arm Phase 1/2 clinical trial in 546 patients with CML treated with prior therapy, severe fluid retention was reported in 14 patients (3%). Specifically, patients had Grade or pleural effusion, patients experienced both Grade or Grade pleural and pericardial effusions, patient experienced Grade peripheral and pulmonary edema, and patient had Grade 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)].. 5.5 Renal Toxicity. An on-treatment decline in estimated glomerular filtration rate (eGFR) has occurred in patients treated with BOSULIF. Table identifies the shift from baseline to lowest observed estimated glomerular filtration rate (eGFR) during BOSULIF therapy for patients in the global Ph+ Leukemia studies. The median duration of therapy with BOSULIF was approximately 17 months (range, 0.03 to 95) for patients in these studies.Table 2: Shift from Baseline to Lowest Observed eGFR Group During Treatment Safety Population in Clinical Studies (n=818)Among the 818 patients, eGFR was missing in patients at baseline or on-therapy.

Consider dose adjustment in patients with baseline and treatment emergent renal impairment [see Dosage and Administration (2.7)]. 5.6 Embryofetal Toxicity. There are no adequate and well controlled studies of BOSULIF in pregnant women. BOSULIF can cause fetal harm when administered to pregnant woman. Bosutinib caused embryofetal toxicities in rabbits at maternal exposures that were greater than the clinical exposure at the recommended bosutinib dose of 500 mg/day. Females of reproductive potential should be advised to avoid pregnancy while being treated with BOSULIF. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1)].

In the patients with AP CML and BP CML, the median duration of BOSULIF treatment was 10 months (range: 0.1 to 140 months) and months (range: 0.03 to 71 months), respectively. The median dose intensity was 406 mg/day, and 456 mg/day, in the AP CML and BP CML cohorts, respectively.. Additional Adverse Reactions From Multiple Clinical TrialsThe following adverse reactions were reported in patients in clinical trials with BOSULIF (less than 10% of BOSULIF-treated patients). They represent an evaluation of the adverse reaction data from all 1372 patients with leukemia who received at least dose of single-agent BOSULIF. These adverse reactions are presented by system organ class and are ranked by frequency. These adverse reactions are included based on clinical relevance and ranked in order of decreasing seriousness within each category.Blood and Lymphatic System Disorders: 0.1% and less than 1% Febrile neutropeniaCardiac Disorders: 1% and less than 10% Pericardial effusion; 0.1% and less than 1% PericarditisEar and Labyrinth Disorders: 1% and less than 10% TinnitusEndocrine Disorders: 1% and less than 10% Hypothyroidism; 0.1% and less than 1% HyperthyroidismGastrointestinal Disorders: 1% and less than 10% Gastritis, Pancreatitis (includes Edematous pancreatitis, Pancreatic enzymes increased, Pancreatitis, Pancreatitis acute, Pancreatitis chronic), Gastrointestinal hemorrhage (includes Anal hemorrhage, Gastric hemorrhage, Gastrointestinal hemorrhage, Intestinal hemorrhage, Lower gastrointestinal hemorrhage, Rectal hemorrhage, Upper gastrointestinal hemorrhage)General Disorders and Administrative Site Conditions: 1% and less than 10% PainImmune System Disorders: 1% and less than 10% Drug hypersensitivity; 0.1% and less than 1% Anaphylactic shockInfections and Infestations: 1% and less than 10% BronchitisInvestigations: 1% and less than 10% Electrocardiogram QT prolonged (includes Electrocardiogram QT prolonged, Long QT syndrome)Metabolism and Nutrition Disorders: 1% and less than 10% DehydrationMusculoskeletal and Connective Tissue Disorders: 1% and less than 10% MyalgiaNervous System Disorders: 1% and less than 10% DysgeusiaRenal and Urinary Disorders: 1% and less than 10% Acute kidney injury, Renal impairment, Renal failureRespiratory, Thoracic and Mediastinal Disorders: 1% and less than 10% Pulmonary hypertension (includes Pulmonary hypertension, Pulmonary arterial hypertension, Pulmonary arterial pressure increased); 0.1% and less than 1% Acute pulmonary edema (includes Acute pulmonary edema, Pulmonary edema), Respiratory failureSkin and Subcutaneous Disorders: 0.1% and less than 1% Erythema multiforme.

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.


8.3 Females and Males of Reproductive Potential. PregnancyBased on findings from animal studies, BOSULIF can cause fetal harm when administered to pregnant woman [see Use in Specific Populations (8.1)]. Females of reproductive potential should have pregnancy test prior to starting treatment with BOSULIF.. Contraception. FemalesBased on findings from animal studies, BOSULIF can cause fetal harm when administered to pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception (methods that result in less than 1% pregnancy rates) during treatment with BOSULIF and for at least weeks after the last dose.. InfertilityThe risk of infertility in females or males of reproductive potential has not been studied in humans. Based on findings from animal studies, BOSULIF may cause reduced fertility in females and males of reproductive potential [see Nonclinical Toxicology (13.1)].

HEPATIC IMPAIRMENT SUBSECTION.


8.7 Hepatic Impairment. Reduce the BOSULIF dosage in patients with hepatic impairment (Child-Pugh A, B, or C) [see Dosage and Administration (2.3, 2.5) and Clinical Pharmacology (12.3)].

LACTATION SECTION.


8.2 Lactation. Risk SummaryNo data are available regarding the presence of bosutinib or its metabolites in human milk or its effects on breastfed child or on milk production. However, bosutinib is present in the milk of lactating rats. Because of the potential for serious adverse reactions in nursing child, breastfeeding is not recommended during treatment with BOSULIF and for at least weeks after the last dose.. Animal DataAfter single radiolabeled bosutinib dose to lactating rats, radioactivity was present in the plasma of suckling offspring for 24 to 48 hours.

POSTMARKETING EXPERIENCE SECTION.


6.2 Postmarketing Experience. The following additional adverse reactions have been identified during post-approval use of BOSULIF. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Blood and Lymphatic System Disorders: Thrombotic microangiopathySkin and Subcutaneous Tissue Disorders: Stevens-Johnson syndrome.

RENAL IMPAIRMENT SUBSECTION.


8.6 Renal Impairment. Reduce the BOSULIF starting dose in patients with moderate (creatinine clearance [CLcr] 30 to 50 mL/min, estimated by Cockcroft-Gault (C-G)) and severe (CLcr less than 30 mL/min, C-G) renal impairment at baseline. For patients who have declining renal function while on BOSULIF who cannot tolerate the starting dose, follow dose adjustment recommendations for toxicity [see Dosage and Administration (2.3, 2.5) and Clinical Pharmacology (12.3)]. BOSULIF has not been studied in patients undergoing hemodialysis.
