Clinical
Bosutinib is used to treat a certain type of chronic myeloid leukemia (CML; a type of cancer of the white blood cells), including treatment in adults who have been recently found to have this condition and in those who can no longer benefit from other medications for CML or who cannot take these medications because of side effects. Bosutinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.

Availability & generic status
This product is an FDA-approved generic. Other versions of the same drug are listed under Therapeutic equivalents, least expensive first.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

( 5.7 )
5.1Gastrointestinal Toxicity Diarrhea, nausea, vomiting, and abdominal pain occur with bosutinib tablets treatment. Monitor and manage patients using standards of care, including antidiarrheals, antiemetics, and fluid replacement. Among 546 adult 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 bosutinib tablets was 3 (range 1 to 268). To manage gastrointestinal toxicity, withhold, dose reduce, or discontinue bosutinib tablets as necessary [see Dosage and Administration (2.3) and Adverse Reactions (6)] . Pediatric use information is approved for PF PRISM CV’s BOSULIF® (bosutinib) tablets.
However, due to PF PRISM CV’s marketing exclusivity rights, this drug product is not labeled with that information.
5.2Myelosuppression Thrombocytopenia, anemia and neutropenia occur with bosutinib tablets 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 bosutinib tablets as necessary [see Dosage and Administration (2.4) and Adverse Reactions (6)] .
5.3Hepatic 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 of 1711 patients in bosutinib tablets clinical trials.
Among the 546 adult patients in a single-arm study in patients with CML who were resistant or intolerant to prior therapy, the incidence of increased ALT 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 increased transaminase of any grade, more than 81% experienced their first increase 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 bosutinib tablets treatment and as clinically indicated. In patients with transaminase elevations, monitor liver enzymes more frequently.
Withhold, dose reduce, or discontinue bosutinib tablets as necessary [see Dosage and Administration (2.3) and Adverse Reactions (6)] .

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Strong and Moderate CYP3A Inhibitors: Avoid concomitant use with bosutinib tablets. ( 7.1 ) • Strong CYP3A Inducers: Avoid concomitant use with bosutinib tablets. ( 7.1 ) • Proton Pump Inhibitors: Use short-acting antacids or H2 blockers as an alternative to proton pump inhibitors. ( 7.1 )
7.1Effect of Other Drugs on Bosutinib Tablets Strong or Moderate CYP3A Inhibitors Avoid the concomitant use of strong or moderate CYP3A inhibitors with bosutinib tablets. Bosutinib is a CYP3A substrate. Concomitant use with a strong or moderate CYP3A inhibitor increases bosutinib C max and AUC [see Clinical Pharmacology (12.3)] which may increase the risk of toxicities.
Strong CYP3A Inducers Avoid the concomitant use of strong CYP3A inducers with bosutinib tablets. Bosutinib is a CYP3A substrate. Concomitant use with a strong CYP3A inducer decreases bosutinib C max and AUC [see Clinical Pharmacology (12.3)] which may reduce bosutinib tablets efficacy.
Proton Pump Inhibitors (PPI) As an alternative to PPIs, use short-acting antacids or H2 blockers and separate dosing by more than 2 hours from bosutinib tablets dosing. Bosutinib displays pH dependent aqueous solubility, Concomitant use with a PPI decreases bosutinib C max and AUC [see Clinical Pharmacology (12.3)] which may reduce bosutinib tablets efficacy.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise women not to breastfeed. ( 8.2 ) Pediatric use information is approved for PF PRISM CV’s BOSULIF® (bosutinib) tablets. However, due to PF PRISM CV’s marketing exclusivity rights, this drug product is not labeled with that information.
8.1Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, bosutinib tablets can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)] . 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 (see Data ) .
Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data In a rat fertility and early embryonic development study, bosutinib was administered orally to female rats for approximately 3 to 6 weeks, depending on day of mating (2 weeks prior to cohabitation with untreated breeder males until gestation day [GD] 7). Increased embryonic resorptions occurred at greater than or equal to 10 mg/kg/day of bosutinib (1.6 and 1.2 times the human exposure at the recommended doses of 400 or 500 mg/day, respectively), and decreased implantations and reduced number of viable embryos at 30 mg/kg/day of bosutinib (3.4 and 2.5 times the human exposure at the recommended doses of 400 or 500 mg/day, respectively).
In an embryo-fetal development 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 2 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 5.1 and 3.8 times the human exposures at the recommended doses of 400 and 500 mg/day, respectively.
Fetal exposure to bosutinib-derived radioactivity during pregnancy was demonstrated in a placental-transfer study in pregnant rats. In a rat pre-and postnatal development study, bosutinib was administered orally to pregnant animals during the period of organogenesis through lactation day 20 at doses of 10, 30, and 70 mg/kg/day. Reduced number of pups born occurred at greater than or equal to 30 mg/kg/day bosutinib (3.4 and 2.5 times the human exposure at the recommended doses of 400 or 500 mg/day, respectively), and increased incidence of total litter loss and decreased growth of offspring after birth occurred at 70 mg/kg/day bosutinib (6.9 and 5.1 times the human exposure at the recommended doses of 400 or 500 mg/day, respectively).
8.2Lactation Risk Summary No data are available regarding the presence of bosutinib or its metabolites in human milk or its effects on a 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 a nursing child, breastfeeding is not recommended during treatment with bosutinib tablets and for 2 weeks after the last dose.
Animal Data After a single radiolabeled bosutinib dose to lactating rats, radioactivity was present in the plasma of suckling offspring for 24 to 48 hours.

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of bosutinib tablets in pediatric patients younger than 1 year of age with newly diagnosed CP Ph+ CML, pediatric patients younger than 1 year of age with CP Ph+ CML that is resistant or intolerant to prior therapy, and pediatric patients with AP Ph+ CML or BP Ph+ CML have not been established. Pediatric use information is approved for PF PRISM CV’s BOSULIF® (bosutinib) tablets. However, due to PF PRISM CV’s marketing exclusivity rights, this drug product is not labeled with that information.
🧓 Geriatric Use ▾
8.5Geriatric Use In the single-arm study in patients with CML who were resistant or intolerant to prior therapy of bosutinib tablets 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.
🆘 Overdosage ▾
10 OVERDOSAGE Experience with bosutinib tablets 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 bosutinib tablets should be observed and given appropriate supportive treatment.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Bosutinib is a TKI. Bosutinib inhibits the BCR-ABLkinase 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 kinase expressed in murine myeloid cell lines. Bosutinib did not inhibit the T315I and V299L mutant cells.
12.2Pharmacodynamics A greater likelihood of response and a greater likelihood of safety events were observed with higher bosutinib exposure in clinical studies. The time course of bosutinib pharmacodynamic response has not been fully characterized. Cardiac Electrophysiology At a single oral dose of 500 mg bosutinib tablet with ketoconazole (a strong CYP3A inhibitor), bosutinib tablets does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics Bosutinib pharmacokinetics were assessed following oral dosing with food in adult patients with CML and were presented as geometric mean (CV%), unless otherwise specified. Bosutinib exhibits dose proportional increases in C max and AUC over the oral dose range of 200 to 800 mg (0.33 to 1.3 times the maximum approved recommended dosage of 600 mg). Bosutinib steady state C max was 127 ng/mL (31%), C trough was 68 ng/mL (39%) and AUC was 2370 ng•h/mL (34%) following multiple oral doses of bosutinib tablets 400 mg; Bosutinib steady state C max was 171 ng/mL (38%),C trough was 91 ng/mL (42%) and AUC was 3150 ng•h/mL (38%) following multiple oral doses of bosutinib tablets 500 mg.
No clinically significant differences in the pharmacokinetics of bosutinib were observed following administration of either the tablet or capsule dosage forms of bosutinib at the same dose, under fed conditions. Absorption The median bosutinib (minimum, maximum) time-to-C max (t max ) was 6 (6, 6) hours following oral administration of a single oral dose of bosutinib tablets 500 mg with food. The absolute bioavailability was 34% in healthy subjects.
Effect of Food Bosutinib C max increased 1.8-fold and AUC increased 1.7-fold when bosutinib tablets were given with a high fat meal to healthy subjects compared to administration under fasted condition. The high-fat meal (800 to 1000 total calories) consisted of approximately 150 protein calories, 250 carbohydrate calories, and 500 to 600 fat calories. Distribution The mean (SD) apparent bosutinib volume of distribution is 6080 (1230) L after an oral dose of 500 mg of bosutinib.
Bosutinib protein binding is 94% in vitro and 96% ex vivo, and is independent of concentration. Elimination The mean (SD) bosutinib terminal phase elimination half-life (t ½ ) was 22.5 (1.7) hours, and the mean (SD) apparent clearance was 189 (48) L/h following a single oral dose of bosutinib tablets. Metabolism Bosutinib is primarily metabolized by CYP3A4.
Excretion Following a single oral dose of [ 14 C] radiolabeled bosutinib without food, 91.3% of the dose was recovered in feces and 3.3% of the dose recovered in urine. Specific Populations Patients with Renal Impairment Bosutinib AUC increased 1.4-fold in subjects with moderate renal impairment (CL cr : 30 to 50 mL/min, estimated by Cockcroft-Gault (C-G)) and increased 1.6-fold in subjects with severe renal impairment (CL cr less than 30 mL/min) following a single oral dose of bosutinib tablets 200 mg (0.33 times the maximum approved recommended dosage of 600 mg).
No clinically significant difference in the pharmacokinetics of bosutinib was observed in subjects with mild renal impairment (CL cr : 51 to 80 mL/min, C-G). Bosutinib tablets has not been studied in patients undergoing hemodialysis. Patients with Hepatic Impairment Bosutinib C max increased 2.4-fold, 2-fold, and 1.5-fold, and AUC increased 2.3-fold, 2-fold, and 1.9-fold in hepatic impairment Child-Pugh A, B, and C, respectively, following a single oral dose of bosutinib tablet 200 mg (0.33 times the maximum approved recommended dosage of 600 mg).

14 CLINICAL STUDIES
14.2Adult Patients with Imatinib-Resistant or -Intolerant Ph+ CP, AP, and BP CML Study 200 (NCT00261846), a single-arm open-label, multicenter study in patients with CML who were resistant or intolerant to prior therapy was conducted to evaluate the efficacy and safety of bosutinib tablets 500 mg once daily in patients with imatinib-resistant or -intolerant CML with separate cohorts for CP, AP, and BP disease previously treated with 1 prior TKI (imatinib) or more than 1 TKI (imatinib followed by dasatinib and/or nilotinib) .
The definition of imatinib resistance included (1) failure to achieve or maintain any hematologic improvement within 4 weeks; (2) failure to achieve a CHR by 3 months, cytogenetic response by 6 months or major cytogenetic response (MCyR) by 12 months; (3) progression of disease after a previous cytogenetic or hematologic response; or (4) presence of a 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 a 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 a 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 1 prior TKI (imatinib) were the rate of attaining MCyR by Week 24 and the duration of MCyR.
The efficacy endpoints for patients with CP CML previously treated with both imatinib and at least 1 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 CHR and overall hematologic response (OHR). The study 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, 506 were considered evaluable for cytogenetic or hematologic efficacy assessment.
Patients were evaluable for efficacy if they had received at least 1 dose of bosutinib tablets and had a valid baseline efficacy assessment. Among evaluable patients, there were 262 patients with CP CML previously treated with 1 prior TKI (imatinib), 112 patients with CP CML previously treated with both imatinib and at least 1 additional TKI, and 132 patients with advanced phase CML previously treated with at least 1 TKI. Median duration of bosutinib tablets treatment was 26 months in patients with CP CML previously treated with 1 TKI (imatinib), 9 months in patients with CP CML previously treated with imatinib and at least 1 additional TKI, 10 months in patients with AP CML previously treated with at least imatinib, and 3 months in patients with BP CML previously treated with at least imatinib.
The 24 week efficacy and MCyR at any time results are summarized in Table 14. Table 14: Efficacy Results in Patients with Ph+ CP CML With Resistance to or Intolerance to Imatinib Prior Treatment With Imatinib Only (N=262 evaluable) n (%) Prior Treatment With Imatinib and Dasatinib or Nilotinib (N=112 evaluable) n (%) By Week 24 MCyR (95% CI) 105 (40.1) (34.1, 46.3) 29 (25.9) (18.1, 35) MCyR any time 156 (59.5) (53.3, 65.5) 45 (40.2) (31, 49.9) Abbreviations: CI=confidence interval; CML=chronic myelogenous leukemia; CP=chronic phase; MCyR=major cytogenetic response; N/n=number of patients; Ph+=Philadelphia chromosome positive.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Bosutinib was not carcinogenic in rats or transgenic mice. The rat 2-year carcinogenicity study was conducted at bosutinib oral doses up to 25 mg/kg in males and 15 mg/kg in females. Exposures at these doses were approximately 1.5 times (males) and 3.1 times (females) the human exposure at the 400 mg dose and 1.2 times (males) and 2.4 times (females) exposure in humans at the 500 mg dose.
The 6-month RasH2 transgenic mouse carcinogenicity study was conducted at bosutinib oral doses up to 60 mg/kg. Bosutinib was not mutagenic or clastogenic in a 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 a 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 1.5 times and equal to the human exposure at the recommended doses of 400 and 500 mg/day, respectively. 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 (1.6 and 1.2 times the human exposure at the recommended doses of 400 and 500 mg/day, respectively), and decreased implantations and reduced number of viable embryos at 30 mg/kg/day of bosutinib (3.4 and 2.5 times the human exposure at the recommended doses of 400 or 500 mg/day, respectively).
