Special populations Elderly patients (≥65 years) No specific dose recommendation is necessary in the elderly. Since there is limited information in the elderly, caution should be exercised in these patients. Renal impairment Patients with serum creatinine >1.5 x ULN were excluded from CML studies. Increasing exposure (AUC) in patients with moderate and severe renal impairment during studies was observed. In patients with moderate renal impairment (CrCL 30 to 50 mL/min, calculated by the Cockroft-Gault formula), the recommended dose of bosutinib is 400 mg daily (see sections 4.4 and 5.2). In patients with severe renal impairment (CrCL <30 mL/min, calculated by the Cockroft-Gault formula), the recommended dose of bosutinib is 300 mg daily (see sections 4.4 and 5.2). Dose escalation to 500 mg once daily for patients with moderate renal impairment or to 400 mg once daily in patients with severe renal impairment may be considered in those who did not experience severe or persistent moderate adverse reactions, under any of the following circumstances. Circumstances for dose escalation - Failure to achieve complete haematologic response (CHR) by week 8 - Failure to achieve complete cytogenetic response (CCyR) by week 12 Cardiac disorders In clinical studies, patients with uncontrolled or significant cardiac disease (e.g. recent myocardial infarction, congestive heart failure or unstable angina) were excluded. Caution should be exercised in patients with relevant cardiac disorders (see section 4.4). Recent or ongoing clinically significant gastrointestinal disorder In clinical studies, patients with recent or ongoing clinically significant gastrointestinal disorder (e.g. severe vomiting and/or diarrhea) were excluded. Caution should be exercised in patients with recent or ongoing clinically significant gastrointestinal disorder (see section 4.4). Paediatric population The safety and efficacy of bosutinib in children less than 18 years of age have not been established. No data are available. Method of administration Bosulif should be taken orally once daily with food (see section 5.2). If a dose is missed the patient should not be given an additional dose. The patient should take the usual prescribed dose on the following day. 4.3 Contraindications Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. Hepatic impairment (see sections 5.1 and 5.2). 4.4 Special warnings and precautions for use Liver function abnormalities Treatment with bosutinib is associated with elevations in serum transaminases (ALT, AST). Transaminase elevations generally occurred early in the course of treatment (of the patients who experienced transaminase elevations of any grade, >80% experienced their first event within the first 3 months). Patients receiving bosutinib should have liver function tests prior to treatment initiation and monthly for the first three months of treatment, and as clinically indicated. Patients with transaminase elevations should be managed by withholding bosutinib temporarily (with consideration given to dose reduction after recovery to grade 1 or baseline), and/or discontinuation of bosutinib. Elevations of transaminases, particularly in the setting of concomitant increases in bilirubin, may be an early indication of drug-induced liver injury and these patients should be managed appropriately (see sections 4.2 and 4.8). Diarrhoea and vomiting Treatment with bosutinib is associated with diarrhoea and vomiting, therefore patients with recent or ongoing clinically significant gastrointestinal disorder should use this medicinal product with caution and only after a careful benefit-risk assessment as respective patients were excluded from the clinical studies. Patients with diarrhoea and vomiting should be managed using standard-of-care treatment, including an antidiarrhoeal or antiemetic medicinal product and/or fluid replacement. In addition, these events can also be managed by withholding bosutinib temporarily, dose reduction, and/or discontinuation of bosutinib (see sections 4.2 and 4.8). The antiemetic agent, domperidone, has the potential to increase QT interval prolongation and to induce “torsade de pointes”- arrhythmias; therefore, co-administration with domperidone should be avoided. It should only be used, if other medicinal products are not efficacious. In these situations an individual benefit-risk assessment is mandatory and patients should be monitored for occurrence of QT prolongation. Myelosuppression Treatment with bosutinib is associated with myelosuppression, defined as anaemia, neutropenia, and thrombocytopenia. Complete blood counts should be performed weekly for the first month and then monthly thereafter, or as clinically indicated. Myelosuppression should/can be managed by withholding bosutinib temporarily, dose reduction, and/or discontinuation of bosutinib (see sections 4.2 and 4.8). Fluid retention Treatment with bosutinib may be associated with fluid retention including pericardial effusion, pleural effusion and pulmonary oedema. Patients should be monitored and managed using standard-of-care treatment. In addition, these events can also be managed by withholding bosutinib temporarily, dose reduction, and/or discontinuation of bosutinib (see sections 4.2 and 4.8). Serum lipase Elevation in serum lipase has been observed. Caution is recommended in patients with previous history of pancreatitis. In case lipase elevations are accompanied by abdominal symptoms, bosutinib should be interrupted and appropriate diagnostic measures considered to exclude pancreatitis (see section 4.2). Infections Bosulif may predispose patients to bacterial, fungal, viral or protozoan infections. Proarrhythmic potential Automated machine-read QTc prolongation without accompanying arrhythmia has been observed. Bosulif should be administered with caution to patients who have a history of or predisposition for QTc prolongation, who have uncontrolled or significant cardiac disease including recent myocardial infarction, congestive heart failure, unstable angina or clinically significant bradycardia, or who are taking medicinal products that are known to prolong the QT interval (e.g.anti-arrhythmic medicinal products and other substances that may prolong QT [section 4.5]). The presence of hypokalaemia and hypomagnesaemia may further enhance this effect. Monitoring for an effect on the QTc interval is advisable and a baseline ECG is recommended prior to initiating therapy with Bosulif and as clinically indicated. Hypokalaemia or hypomagnesaemia must be corrected prior to Bosulif administration and should be monitored periodically during therapy. Renal impairment Treatment with bosutinib may result in a clinically significant decline in renal function in CML patients. A decline over time in estimated glomerular filtration rate (eGFR) has been observed in patients treated with bosutinib in clinical studies. Patients with pretreated and advanced stage Ph+ leukemias in the global single-arm Phase 1/2 clinical trial showed a median decline from baseline in eGFR of 5.29 ml/min/1.73 m2 at 3 months , of 7.11 ml/min/1.73 m2 at 6 months and of 10.92 ml/min/1.73 m2 at 36 months. Treatment-naïve CML patients showed a median decline from baseline in eGFR of 5.06 ml/min/1.73 m2 at 3 months, of 7.65 ml/min/1.73 m2 at 6 months and of 15.62 ml/min/1.73 m2 at 48 months. It is important that renal function is assessed prior to treatment initiation and closely monitored during therapy with bosutinib, with particular attention in those patients who have preexisting renal compromise or in those patients exhibiting risk factors for renal dysfunction, including concomitant use of medicinal products with potential for nephrotoxicity, such as diuretics, ACE inhibitors, angiotensin receptor blockers and nonsteroidal anti-inflammatory drugs (NSAIDs). In a renal impairment study, bosutinib exposures were increased in subjects with moderately and severely impaired renal function. Dose reduction is recommended for patients with moderate or severe renal impairment (see sections 4.2 and 5.2). Patients with serum creatinine > 1.5 x ULN were excluded from the CML studies. Based on a population pharmacokinetic analysis increasing exposure (AUC) in patients with moderate and severe renal impairment at initiation of treatment during studies was observed (see sections 4.2 and 5.2). Clinical data is very limited (n = 3) for CML patients with moderate renal impairment receiving an escalated dose of 600 mg bosutinib. CYP3A inhibitors The concomitant use of Bosulif with potent or moderate CYP3A inhibitors should be avoided, as an increase in bosutinib plasma concentration will occur (see section 4.5). Selection of an alternate concomitant medicinal product with no or minimal CYP3A inhibition potential, if possible, is recommended. If a potent or moderate CYP3A inhibitor must be administered during Bosulif treatment, an interruption of Bosulif therapy or a dose reduction in Bosulif should be considered. CYP3A inducers The concomitant use of Bosulif with potent or moderate CYP3A inducers should be avoided as a decrease in bosutinib plasma concentration will occur (see section 4.5). Food effect Grapefruit products, including grapefruit juice and other foods that are known to inhibit CYP3A should be avoided (see section 4.5). 4.5 Interaction with other medicinal products and other forms of interaction Effects of other medicinal products on bosutinib CYP3A inhibitors The concomitant use of bosutinib with potent (e.g. ritonavir, indinavir, nelfinavir, saquinavir, ketoconazole, itraconazole, voriconazole, posaconazole, troleandomycin, clarithromycin, telithromycin, boceprevir, telaprevir, mibefradil, nefazodone, conivaptan, grapefruit products including grapefruit juice) or moderate (e.g. fluconazole, darunavir, erythromycin, diltiazem, dronedarone, atazanavir, aprepitant, amprenavir, fosamprenavir, imatinib, verapamil, tofisopam ciprofloxacin) CYP3A inhibitors should be avoided, as an increase in bosutinib plasma concentration will occur. Caution should be exercised if mild CYP3A inhibitors are used concomitantly with bosutinib. Selection of an alternate concomitant medicinal product with no or minimal CYP3A enzyme inhibition potential, if possible, is recommended. If a potent or moderate CYP3A inhibitor must be administered during Bosulif treatment, an interruption of Bosulif therapy or a dose reduction in Bosulif should be considered. In a study of 24 healthy subjects in whom five daily doses of 400 mg ketoconazole were co-administered with a single dose of 100 mg bosutinib under fasting conditions, ketoconazole increased bosutinib Cmax by 5.2-fold, and bosutinib AUC in plasma by 8.6-fold, as compared with administration of bosutinib alone. CYP3A inducers The concomitant use of Bosulif with potent (e.g. rifampicin, phenytoin, carbamazepine, St. John's Wort, rifabutin, phenobarbital) or moderate (e.g. bosentan, nafcillin, efavirenz, modafinil, etravirine) CYP3A inducers should be avoided, as a decrease in bosutinib plasma concentration will occur. Based on the large reduction in bosutinib exposure that occurred when bosutinib was co-administered with rifampicin, increasing the dose of Bosulif when co-administering with potent or moderate CYP3A inducers is unlikely to sufficiently compensate for the loss of exposure. Caution is warranted if mild CYP3A inducers are used concomitantly with Bosulif. Following concomitant administration of a single dose bosutinib with six daily doses of 600 mg rifampicin, in 24 healthy subjects in fed state bosutinib exposure (Cmax and AUC in plasma) decreased to 14% and 6%, respectively, of the values when bosutinib 500 mg was administered alone. Proton pump inhibitors (PPIs) Caution should be exercised when administering Bosulif concomitantly with proton pump inhibitors (PPIs). Short-acting antacids should be considered as an alternative to PPIs and administration times of bosutinib and antacids should be separated (i.e. take bosutinib in the morning and antacids in the evening) whenever possible. Bosutinib displays pH-dependent aqueous solubility in vitro. When a single oral dose of bosutinb (400 mg) was co-administered with multiple-oral doses of lansoprazole (60 mg) in a study of 24 healthy fasting subjects, bosutinib Cmax and AUC decreased to 54% and 74%, respectively, of the values seen when bosutinib (400 mg) was given alone. Effects of bosutinib on other medicinal products Caution should be used if bosutinib is administered with medicinal products that are substrates of P-glycoprotein (P-gp). An in vitro study suggests that bosutinib may have the potential to increase the plasma concentrations of medicinal products that are P-gp substrates, such as digoxin, colchicine, tacrolimus and quinidine; chemotherapeutic agents such as etoposide, doxorubicin, and vinblastine; immunosuppressive agents; glucocorticoids like dexamethasone; HIV-type 1 antiretroviral therapy agents like protease inhibitors and nonnucleoside reverse transcriptase inhibitors. An in vitro study indicates that drug-drug interactions are unlikely to occur at therapeutic doses as a result of induction by bosutinib on the metabolism of medicinal products that are substrates for CYP1A2, CYP2B6, CYP2C9, CYP2C19, and CYP3A4. In vitro studies indicate that clinical drug-drug interactions are unlikely to occur at therapeutic doses as a result of inhibition by bosutinib on the metabolism of medicinal products that are substrates for CYP1A2, CYP2A6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A4/5. Anti-arrhythmic medicinal products and other substances that may prolong QT Bosutinib should be used with caution in patients who have or may develop prolongation of QT, including those patients taking anti-arrhythmic medicinal products such as amiodarone, disopyramide, procainamide, quinidine and sotalol or other medicinal products that may lead to QT prolongation such as chloroquine, halofantrine, clarithromycin, domperidone, haloperidol, methadone and moxifloxacin (see section 4.4). 4.6 Fertility, pregnancy and lactation Women of childbearing potential Women of childbearing potential should be advised to use effective contraception and avoid becoming pregnant while receiving Bosulif. In addition, the patient should be advised that vomiting or diarrhoea may reduce the efficacy of oral contraceptives by preventing full absorption. Pregnancy There are limited amount of data in pregnant women from the use of Bosulif. Studies in animals have shown reproductive toxicity (see section 5.3). Bosulif is not recommended for use during pregnancy, or in women of childbearing potential not using contraception. If Bosulif is used during pregnancy, or the patient becomes pregnant while taking Bosulif, she should be apprised of the potential hazard to the foetus. Breast-feeding It is unknown whether bosutinib and its metabolites are excreted in human milk. A study of [14C] radiolabelled bosutinib in rats demonstrated excretion of bosutinib-derived radioactivity in breast milk (see section 5.3). A potential risk to the breast-feeding infant cannot be excluded. Breast-feeding should be discontinued during treatment with bosutinib. Fertility Based on non-clinical findings, bosutinib has the potential to impair reproductive function and fertility in humans (see section 5.3). 4.7 Effects on ability to drive and use machines Bosulif has no or negligible influence on the ability to drive and use machines. However, if a patient taking bosutinib experiences dizziness, fatigue, visual impairment or other undesirable effects with a potential impact on the ability to drive or use machines safely, the patient should refrain from these activities for as long as the undesirable effects persist. 4.8 Undesirable effects Summary of safety profile A total of 870 Ph+ leukaemia patients received at least 1 dose of single-agent bosutinib. These patients were either newly diagnosed, Ph+ chronic phase CML or were resistant or intolerant to prior therapy with Ph+ chronic, accelerated, or blast phase CML or Ph+ acute lymphoblastic leukaemia (ALL). Of these patients, 248 are from the Phase 3 study in previously untreated CML patients, 570 and 52 are from two Phase 1/2 studies in previously treated Ph+ leukaemias. The median duration of therapy was 16.6 months (range: 0.03 to 30.4 months), 11 months (range: 0.03 to 55.1 months), and 5.5 months (range: 0.3 to 30.4 months), respectively. At least 1 adverse reaction of any toxicity grade was reported for 848 (97.5%) patients. The most frequent adverse reactions reported for ≥20% of patients were diarrhoea (78.5%), nausea (42.1%), thrombocytopenia (38.5%), vomiting (37.1%), abdominal pain (33.4%), rash (32.4%), anaemia (27.4 %), pyrexia (23.4%), and alanine aminotranserase increased (22.3%). At least 1 Grade 3 or Grade 4 adverse reaction was reported for 531 (61.0%) patients. The Grade 3 or Grade 4 adverse reactions reported for ≥5% of patients were thrombocytopenia (25.4%), anaemia (12.3%), neutropenia (11.5%), alanine aminotransferase increased (10.2%), diarrhoea (9.1%), rash (6.1%), lipase increased (5.2%) and aspartate aminotransferase increased (5.0%). Tabulated list of adverse reactions The following adverse reactions were reported in patients in bosutinib clinical studies (Table 2). These represent an evaluation of the adverse reaction data from 870 patients with newly diagnosed Ph+ chronic phase CML or with Ph+ chronic, accelerated, or blast phase CML or Ph+ acute lymphoblastic leukaemia (ALL) resistant or intolerant to prior therapy and who have received at least 1 dose of single-agent bosutinib. These adverse reactions are presented by system organ class and frequency. Frequency categories are defined as: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. Table 2 - Adverse reactions for bosutinib

Description of selected adverse reactions The descriptions included below are based on the safety population of 870 patients who received at least 1 dose of bosutinib in either a Phase 3 study in newly diagnosed Ph+ CP CML or in single-arm Phase 1/2 clinical studies that enrolled patients who were resistant or intolerant to prior therapy with Ph+ chronic, accelerated, or blast phase CML, or Ph+ ALL. Blood and lymphatic system disorders Of the 224 (26%) patients with reports of adverse reactions of anaemia, 5 patients discontinued bosutinib due to anaemia. In these patients, the maximum toxicity of Grade 1 or 2 was experienced in 125 (56%) patients, Grade 3 in 76 patients (34%), and Grade 4 in 23 (10%) patients. Among these patients, the median time to first event was 28 days (range, 1 to 658 days) and the median duration per event was 12 days (range, 1 to 502 days). Of the 135 (16%) patients with reports of adverse reactions of neutropenia, 13 patients discontinued bosutinib due to neutropenia. Maximum Grade 1 or 2 events were experienced by 37 (27%) patients. The maximum toxicity of Grade 3 neutropenia was experienced in 66 (49%) patients and of Grade 4 in 32 (24%) patients. The median time to first event was 56 days (range, 2 to 840 days) and the median duration per event was 14 days (range, 1 to 454 days). Of the 326 (38%) patients with reports of adverse reactions of thrombocytopenia, 29 (9%) patients discontinued treatment with bosutinib due to thrombocytopenia. Maximum grade 1 or 2 events were experienced by 115 (35%) patients. The maximum toxicity of thrombocytopenia of Grade 3 was experienced in 124 (38%) patients and Grade 4 in 87 (27%) patients. Among patients with thrombocytopenia AEs, the median time to first event was 28 days (range, 1 to 968 days) and median duration per event was 14 days (range, 1 to 666 days). Hepatobiliary disorders Among patients with reports of adverse reactions of elevations in either ALT or AST (all grades), the median time of onset observed in the study was 28 days with a range of onset 6 to 841 days for ALT and 1 to 680 days for AST. The median duration of an event was 15 days (range, 1 to 336 days), and 14 days ( range, 1 to 595 days) for ALT and AST, respectively. In the entire development program, concurrent elevation in transaminases ≥ 3 x ULN and bilirubin > 2 x ULN with alkaline phosphatase <2 x ULN occurred without obvious causes in 1/1209 (<0.1%) subjects treated with bosutinib. This finding was in a study of bosutinib in combination with letrozole in a patient with metastatic breast cancer. Gastrointestinal disorders Of the 681 (78%) patients that experienced diarrhoea, 665 patients had drug-related events of diarrhoea and 8 patients discontinued bosutinib due to this event. Concomitant medicines were given to treat diarrhoea in 461 (68%) of patients. The maximum toxicity of diarrhoea was Grade 1 or 2 in 89% of patients, Grade 3 in 11% of patients; one patient (<1%) experienced a Grade 4 event. Among patients with diarrhoea, the median time to first event was 2 days (range, 1 to 594 days) and the median duration of any grade of diarrhoea was 2 days (range, 1 to 910 days). Among the 681 patients with diarrhoea, 104 patients (15%) were managed with treatment interruption and of these 98 (94%) were rechallenged with bosutinib. Of those who were rechallenged, 95 (97%) did not have a subsequent event or did not discontinue bosutinib due to a subsequent event of diarrhoea. Cardiac disorders Three patients (0.3%) experienced QTcF interval prolongation (greater than 500 ms). Eight (0.9%) patients, including 2 of those with QTcF interval prolongation of greater than 500 ms, experienced QTcF increase from baseline exceeding 60 ms. Patients with uncontrolled or significant cardiovascular disease including QT interval prolongation, at baseline, were not included in clinical studies (see sections 5.1 and 5.3). Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard 4.9 Overdose Experience with bosutinib overdose in clinical studies was limited to isolated cases. Patients who take an overdose of bosutinib should be observed and given appropriate supportive treatment. 5. Pharmacological properties 5.1 Pharmacodynamic properties Pharmacotherapeutic group: Antineoplastic agents, protein kinase inhibitors, ATC code: L01XE14. Mechanism of action Bosutinib belongs to a pharmacologic class of medicinal products known as kinase inhibitors. Bosutinib inhibits the abnormal Bcr-Abl kinase that promotes CML. Modeling studies indicate that bosutinib binds the kinase domain of Bcr-Abl. Bosutinib is also an inhibitor of Src family kinases including Src, Lyn and Hck; Bosutinib minimally inhibits PDGF receptor and c-Kit In in vitro studies, bosutinib inhibits proliferation and survival of established CML cell lines, Ph+ acute lymphoblastic leukaemia cell lines, and patient-derived primary primitive CML cells. Bosutinib inhibited 16 of 18 imatinib-resistant forms of Bcr-Abl expressed in murine myeloid cell lines. Bosutinib treatment reduced the size of CML tumours growing in nude mice and inhibited growth of murine myeloid tumours expressing imatinib-resistant forms of Bcr-Abl. Bosutinib also inhibits receptor tyrosine kinases c-Fms, EphA and B receptors, Trk family kinases, Axl family kinases, Tec family kinases, some members of the ErbB family, the non-receptor tyrosine kinase Csk, serine/threonine kinases of the Ste20 family and two calmodulin-dependent protein kinases. Pharmacodynamic effects The effect of bosutinib 500 mg administration on corrected QT interval (QTc) was evaluated in a randomized, single-dose, double-blind (with respect to bosutinib), crossover, placebo- and open-label moxifloxacin-controlled study in healthy subjects. The data from this study indicate that bosutinib does not prolong the QT interval in healthy subjects at the recommended dose of 500 mg daily with food, and under conditions that give rise to supratherapeutic plasma concentrations. Following administration of a single oral dose of bosutinib 500 mg (therapeutic dose) and bosutinib 500 mg with ketoconazole 400 mg (to achieve supratherapeutic concentrations of bosutinib) in healthy subjects, the upper bound of the one-sided 95% CI around the mean change in QTc was less than 10 ms at all post dose time points, and no AEs suggestive of QTc interval prolongation were observed. In a study in liver impaired subjects an increasing frequency of QTc prolongation >450 ms with declining hepatic function was observed. In the Phase 1/2 clinical study in patients with previously treated Ph+ leukaemias, QTcF interval changes >60 ms from baseline were observed 6 (1.1%) of 562 patients. In the Phase 3 clinical study in patients with newly diagnosed Ph+ CP CML, QTcF interval changes >60 ms from baseline were observed in 2 (0.8%) of 248 patients receiving bosutinib. A proarrhythmic potential of bosutinib cannot be ruled out. Clinical efficacy Clinical study in imatinib-resistant or intolerant CML in chronic phase, accelerated phase, and blast phase. A single-arm, Phase 1/2 open-label, multicenter trial 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 tyrosine kinase inhibitor (TKI) (imatinib) or more than one TKI (imatinib followed by dasatinib and/or nilotinib). There were 570 patients treated with Bosulif in this trial including CP CML patients previously treated with only one prior TKI (imatinib), CP CML patients previously treated with imatinib and at least 1 additional TKI (dasatinib and/or nilotinib), CML patients in accelerated or blast phase previously treated with at least one TKI (imatinib) and patients with Ph+ ALL previously treated with at least one TKI (imatinib). The primary efficacy endpoint of the study was the major cytogenetic response (MCyR) rate at week 24 in patients with imatinib-resistant CP CML previously treated with only one prior TKI (imatinib). Other efficacy endpoints include the cumulative MCyR rate, time to and duration of MCyR, and time to and duration of CHR, in patients with CP CML previously treated with only one prior TKI (imatinib). For patients previously treated with both imatinib and at least 1 additional TKI, the endpoints include the cumulative MCyR rate, time to and duration of MCyR, and time to and duration of CHR. For patients with AP and BP CML previously treated with at least one prior TKI (imatinib), the endpoints were cumulative overall haematologic response (OHR) and time to and duration of OHR. Other efficacy endpoints include transformation to AP/BP, progression free survival and overall survival for all cohorts. Chronic phase The efficacy results for Ph+ CP CML patients previously treated with imatinib and at least 1 additional TKI (minimum follow-up 25 months and median treatment duration of 8.6 months) and the results for Ph+ CP CML patients previously treated with only imatinib (minimum follow-up 24 months and median treatment duration of 22.1 months) are presented in Table 3. Efficacy results in the subgroup of patients corresponding to the approved indication are described below. Efficacy for patients identified within the Phase 1/2 study population who failed either imatinib alone or imatinib in addition to one or both second-generation TKIs (dasatinib and nilotinib) and for whom, based on the presence of co-morbidities, a history of TKI intolerance, or a BCR-ABL resistance mutation, the remaining approved TKI(s) are not considered appropriate treatment options was reviewed. Of the 52 patients identified, 36 patients were in the CP CML subpopulation (21 who had previously received 2 prior TKIs and 15 who had received 1 prior TKI). Of the 21 CP CML patients treated with Bosulif following failure of imatinib and 1 additional second-generation TKI identified, 9 of these patients had MCyR or better including 2 patients with complete molecular response (CMR), 1 patient with major molecular response (MMR), 4 patients with CCyR, and 2 patients with partial cytogenetic response (PCyR) and had a treatment duration exceeding 24 weeks. In addition, 7 other patients had a response of CHR on Bosulif treatment. Among the 9 patients with a response of MCyR or better, duration of MCyR ranged from 8 to 204 weeks with a treatment duration ranging from 35 to 215+ weeks. There were 15 patients who received imatinib and no other second-generation TKI who met these criteria. Of these 15 patients with unmet medical need who had received prior imatinib only, 9 patients had a response on Bosulif treatment of MCyR or better, including 3 patients with CMR, 1 patient with MMR, 4 patients with CCyR, and 1 patients with PCyR with a duration of MCyR ranging from 12 to 155 weeks and a treatment duration ranging from 24 to 197+ weeks. Accelerated and blast phase CML patients The efficacy results for AP (minimum follow-up 12 months and median treatment duration of 10 months) and BP (minimum follow-up 18 months and median treatment duration of 2.8 months) Ph+ CML patients are present in Table 3. Efficacy results in the subgroup of patients corresponding to the approved indication are described below. There was also a subpopulation of 16 advanced phase patients (5 AP CML and 11 BP CML patients) that failed treatment with either imatinib alone or imatinib in addition to one or both second-generation TKIs (dasatinib and nilotinib) and for whom, based on the presence of co-morbidities, a history of TKI intolerance, or a BCR-ABL resistance mutation, the remaining approved TKI(s) were not considered appropriate treatment options. Of these, 4 of the 5 AP patients had notable treatment duration with a range from 46 to 114 weeks with responses including CMR (1 patient), CCyR (2 patients) and major haematologic response (MaHR) (1 patient) with 1 patient still on treatment. Among the 11 BP CML patients, 3 patients remained on treatment for more than 24 weeks with notable responses (2 patients with a CCyR and 1 patient with a MaHR) and a treatment duration ranging from 46 to 118 weeks with one patient still on treatment. Table 3 - Efficacy results in previously treated patients with chronic and advanced phase CML*
Snapshot date: 15Feb12 for CP treated with imatinib and at least one other TKI and 28Mar11 for AP and BP and CP treated with imatinib only. Abbreviations: K-M=Kaplan-Meier, N/A=Not applicable, N/R = Not reached, N/E=Not estimable, CI=confidence interval, MCyR=major cytogenetic response, CCyR=complete cytogenetic response, OHR= Overall haematologic response, CHR = Complete haematologic response. Cytogenetic Response criteria: Major Cytogenetic response included Complete (0% Ph+ metaphases from bone marrow or <1% positive cells from fluorescent in situ hybridization [FISH]) or partial (1%-35%) cytogenetic responses. Cytogenetic responses were based on the percentage of Ph+ metaphases among >/= 20 metaphase cells in each bone marrow sample.

Abbreviations: MCyR = major cytogenetic response, Resp=responders, Eval = evaluable. Note: Baseline mutations were identified before the patient's first dose of study drug. a The percentage is based on number of patients with baseline mutation assessment. b The evaluable population includes patients who had a valid baseline disease assessment. c 1 subject had more than 1 mutation in this category. One patient with the E255V mutation previously treated with nilotinib achieved CHR as best response. In vitro testing indicated that bosutinib had limited activity against the T315I or the V299L mutation. Therefore, clinical activity in patients with these mutations is not expected. Clinical study in chronic phase previously untreated CML An international, multicenter, randomized, open-label, comparative Phase 3 efficacy and safety study was conducted in newly diagnosed Ph+ CP CML patients. Patients were randomized in a 1:1 fashion to treatment with either bosutinib 500 mg once daily or imatinib 400 mg once daily. The primary objective of the study was to compare the CCyR at 1 year in patients with newly diagnosed Ph+ CP CML who received bosutinib compared with those who received imatinib. The primary objective was not met. Other efficacy objectives were to estimate the MMR, to estimate the duration of CCyR, CHR, and MMR, and to estimate the time to transformation to AP/BP. A total of 250 patients randomized to receive bosutinib and 252 patients randomized to receive imatinib comprised the ITT population. Randomization of patients was stratified by Sokal score and geographic region. With a minimum of 24 months following the last patient's first visit, and median treatment duration of 27.51 months, 62.9 % of patients randomized to the bosutinib arm and 71.3% of patients randomized to the imatinib group were still receiving first-line treatment. Efficacy results are presented in Table 5. Based on these results, a positive benefit-risk of bosutinib in patients with previously untreated CML in the chronic phase has not been established.

Paediatric population The European Medicines Agency has deferred the obligation to submit the results of studies with Bosulif in one or more subsets of the paediatric population in CML (see section 4.2 for information on paediatric use). Conditional approval This medicinal product has been authorised under a so-called “conditional approval” scheme. This means that further evidence on this medicinal product is awaited. The European Medicines Agency will review new information on this medicinal product at least every year and this SmPC will be updated as necessary. 5.2 Pharmacokinetic properties Absorption Following administration of a single dose of 500 mg bosutinib with food in healthy subjects, absorption was relatively slow, with a median time-to-peak concentration (tmax) reached after 6 hours. The mean +SD Cmax value was 112 +29 ng/mL, and the mean AUC was 2740 + 790 ng•h/mL. Bosutinib exhibits dose proportional increases in AUC and Cmax, over the dose range of 200 to 600 mg. Food increased bosutinib Cmax 1.8-fold and bosutinib AUC 1.7-fold compared to the fasting state. After 15 daily dosing of bosutinib tablet with food in patients with CML, the mean Cmax value was 200 +12 ng/mL, and the mean AUC was 3650 + 425 ng•h/mL. The solubility of bosutinib is pH-dependent and absorption is reduced when gastric pH is increased (see section 4.5). Distribution Following a single dose of 500 mg bosutinib with food, bosutinib had a mean apparent volume of distribution of 9,560 ± 3,030 L, suggesting that bosutinib is extensively distributed to extra-vascular tissue. Bosutinib was highly bound to human plasma proteins in vitro (94%) and ex vivo in healthy subjects (96%), and binding was not concentration-dependent. Biotransformation In vitro and in vivo studies indicated that bosutinib (parent compound) undergoes predominantly hepatic metabolism in humans. Following administration of single or multiple doses of bosutinib (400 or 500 mg) to humans, the major circulating metabolites appeared to be oxydechlorinated (M2) and N-desmethylated (M5) bosutinib, with bosutinib N-oxide (M6) as a minor circulating metabolite. The systemic exposure of N-desmethylated metabolite was 25% of the parent compound, while the oxydechlorinated metabolite was 19% of the parent compound. All three metabolites exhibited activity that was ≤ 5% that of bosutinib in a Src-transformed fibroblast anchorage-independent proliferation assay. In faeces, bosutinib and N-desmethyl bosutinib were the major drug-related components. In vitro studies with human liver microsomes indicated that the major cytochrome P450 isozyme involved in the metabolism of bosutinib is CYP3A4 and drug interaction studies have shown that ketoconazole and rifampicin had marked effect on the pharmacokinetics of bosutinib (see section 4.5). No metabolism of bosutinib was observed with CYPs 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, or 3A5. Elimination After a single oral dose of 500 mg bosutinib with food, the mean elimination half-life was approximately 34 hours, and the mean clearance (Cl/F) was 197 + 57 L/h. In a mass-balance study with oral bosutinib, an average of 94.6% of the total dose was recovered in 9 days; faeces (91.3%) was the major route of excretion, with 3.29% of the dose recovered in urine. 75% of the dose recovered within 96 hours. Excretion of unchanged bosutinib in urine was low with approximately 1% of the dose in both healthy subjects and those with advanced malignant solid tumours. Special populations Hepatic impairment: A 200 mg dose of bosutinib administered with food was evaluated in a cohort of 18 hepatically impaired subjects (Child-Pugh classes A, B, and C) and 9 matched healthy subjects. Cmax of bosutinib in plasma increased 2.4-fold, 2-fold, and 1.5-fold, respectively, in Child-Pugh classes A, B, and C; and bosutinib AUC in plasma increased 2.3-fold, 2-fold, and 1.9-fold, respectively. The t1/2 of bosutinib increased in hepatic impaired patients as compared to the healthy subjects. Renal impairment: In a renal impairment study, a single dose of 200 mg bosutinib was administered with food to 26 subjects with mild, moderate or severe renal impairment and to 8 matching healthy volunteers. Renal impairment was based on CrCl (calculated by the Cockcroft-Gault formula) of <30 mL/min (severe renal impairment), 30 ≤CrCl ≤50 mL/min (moderate renal impairment), or 50 <CrCl ≤80 mL/min (mild renal impairment). Subjects with moderate and severe renal impairment had an increase in AUC over healthy volunteers of 35% and 60%, respectively. Maximal exposure Cmax increased by 28% and 34% in the moderate and severe groups, respectively. Bosutinib exposure was not increased in subjects with mild renal impairment. The elimination half-life of bosutinib in subjects with renal impairment was similar to that in healthy subjects. Based on population pharmacokinetic modelling, a daily dose of 400 mg in patients with moderate renal impairment and a daily dose of 300 mg in patients with severe renal impairment are predicted to result in a similar AUC to that seen in patients with normal renal function receiving 500 mg daily. Age, gender and race: No formal studies have been performed to assess the effects of these demographic factors. Population pharmacokinetic analyses in patients with Ph + leukaemia or malignant solid tumour indicate that there are no clinically relevant effects of age, gender, body weight, race. Paediatric population: Bosulif has not yet been studied in children less than 18 years of age. 5.3 Preclinical safety data Bosutinib has been evaluated in safety pharmacology, repeated dose toxicity, genotoxicity, reproductive toxicity and photoxicity studies. Safety pharmacology Bosutinib did not have effects on respiratory functions. In a study of the central nervous system (CNS), bosutinib treated rats displayed decreased pupil size and impaired gait. A no observed effect level (NOEL) for pupil size was not established, but the NOEL for impaired gait occurred at exposures > 8-fold those in CML patients receiving the 500 mg dose. Bosutinib activity in vitro in hERG assays suggested a potential for prolongation of cardiac ventricular repolarization (QT interval). In an oral study of bosutinib in dogs, bosutinib did not produce changes in blood pressure, abnormal atrial or ventricular arrhythmias, or prolongation of the PR, QRS, or QTc interval of the electrocardiogram (ECG) at exposures up to 2-fold (comparing Cmax and based on unbound fraction in the respective species) the clinical exposure at the 500 mg dose. A delayed increase in heart rate was observed. In an intravenous study in dogs, transient increases in heart rate and decreases in blood pressure and minimal prolongation of the QTc interval (<10 msec) were observed at exposures ranging from 4.2 to 14.6-fold the clinical exposure following the 500 mg dose. The relationship between the observed effects and medicinal product treatment were inconclusive. Repeated-dose toxicity Repeated-dose toxicity studies in rats of up to six months in duration and in dogs up to nine months in duration revealed the gastrointestinal system to be the primary target organ of toxicity of bosutinib. Clinical signs of toxicity included foecal changes and were associated with decreased food consumption and body weight loss which occasionally led to death or elective euthanasia. Histopathologically, luminal dilation, goblet cell hyperplasia, haemorrhage, erosion, and oedema of the intestinal tract, and sinus erythrocytosis and haemorrhage in the mesenteric lymph nodes, were observed. The liver was also identified as a target organ in rats. Toxicities were characterized by an increase in liver weights in correlation with hepatocellular hypertrophy which occurred in the absence of elevated liver enzymes or microscopic signs of hepatocellular cytotoxicity, and is of unknown relevance to humans. The exposure camparison across species indicates that exposures that did not elicit adverse effects in the 6- and 9-month toxicity studies in rats and dogs, respectively, were similar to or slightly exceeding the exposure in humans after multiple dosing of 500 mg. Genotoxicity Genotoxicity studies in bacterial in vitro systems and in mammalian in vitro and in vivo systems with and without metabolic activation did not reveal any evidence for a mutagenic potential of bosutinib. Reproductive toxicity and development toxicity In a rat fertility study, fertility was slightly decreased in males. Females were observed with increased embryonic resorptions, and decreases in implantations and viable embryos. The dose at which no adverse reproductive effects were observed in males (30 mg/kg/day) and females (3 mg/kg/day) resulted in exposures equal to 0.5 and 0.2-times, respectively, the human exposure resulting from the clinical dose of 500 mg (based on unbound AUC in the respective species). Foetal exposure to bosutinib-derived radioactivity during pregnancy was demonstrated in a placental transfer study in gravid Sprague-Dawley rats. The no-observable-adverse-effect level for developmental toxicity in rats occurred at exposures equal to 1.2-times the human exposure at the 500 mg dose. In a rabbit developmental toxicity study at the maternally toxic dosage, there were foetal anomalies observed (fused sternebrae, and two foetuses had various visceral observations), and a slight decrease in foetal body weight. The exposure at the highest dose tested in rabbits (10 mg/kg) that did not result in adverse foetal effects was 0.7-times that in humans at the 500 mg dose (based on unbound AUC in the respective species). Following a single oral (10 mg/kg) administration of [14C] radiolabelled bosutinib to lactating Sprague-Dawley rats, radioactivity was readily excreted into breast milk as early as 0.5 hr after dosing. Concentration of radioactivity in milk was up to 8-fold higher than in plasma. This allowed measurable concentrations of radioactivity to appear in the plasma of nursing pups. Carcinogenicity Bosutinib was not carcinogenic in the 2-year rat carcinogenicity study. Phototoxicity Bosutinib has demonstrated the ability to absorb light in the UV-B and UV-A range and is distributed into the skin and uveal tract of pigmented rats. However, bosutinib did not demonstrate a potential for phototoxicity of the skin or eyes in pigmented rats exposed to bosutinib in the presence of UV radiation at bosutinib exposures at least 8-times greater than human exposure resulting from the 500 mg dose. 6.
