4. CLINICAL PARTICULARS
4.1 Therapeutic indications
Tasigna is indicated for the treatment of:
- adult and paediatric patients with newly diagnosed Philadelphia chromosome positive chronicmyelogenous leukaemia (CML) in the chronic phase,
- adult patients with chronic phase and accelerated phase Philadelphia chromosome positive CMLwith resistance or intolerance to prior therapy including imatinib. Efficacy data in patients with
CML in blast crisis are not available,
- paediatric patients with chronic phase Philadelphia chromosome positive CML with resistanceor intolerance to prior therapy including imatinib.
4.2 Posology and method of administration
Therapy should be initiated by a physician experienced in the diagnosis and the treatment of patientswith CML.
PosologyTreatment should be continued as long as clinical benefit is observed or until unacceptable toxicityoccurs.
If a dose is missed the patient should not take an additional dose, but take the usual prescribed nextdose.
Posology for Philadelphia chromosome positive CML adult patients
The recommended dose is:
- 300 mg twice daily in newly diagnosed patients with CML in the chronic phase,
- 400 mg twice daily in patients with chronic or accelerated phase CML with resistance orintolerance to prior therapy.
Posology for Philadelphia chromosome positive CML paediatric patients
Dosing in paediatric patients is individualised and is based on body surface area (mg/m2). Therecommended dose of nilotinib is 230 mg/m2 twice daily, rounded to the nearest 50 mg dose (to amaximum single dose of 400 mg) (see Table 1). Different strengths of Tasigna hard capsules can becombined to attain the desired dose.
There is no experience with treatment of paediatric patients below 2 years of age. There are no data innewly diagnosed paediatric patients below 10 years of age and limited data in imatinib-resistant orintolerant paediatric patients below 6 years of age.

Adult Philadelphia chromosome positive CML patients in chronic phase who have been treated withnilotinib as first-line therapy and who achieved a sustained deep molecular response (MR4.5)
Discontinuation of treatment may be considered in eligible adult Philadelphia chromosome positive(Ph+) CML patients in chronic phase who have been treated with nilotinib at 300 mg twice daily for aminimum of 3 years if a deep molecular response is sustained for a minimum of one year immediatelyprior to discontinuation of therapy. Discontinuation of nilotinib therapy should be initiated by aphysician experienced in the treatment of patients with CML (see sections 4.4 and 5.1).
Eligible patients who discontinue nilotinib therapy must have their BCR-ABL transcript levels andcomplete blood count with differential monitored monthly for one year, then every 6 weeks for thesecond year, and every 12 weeks thereafter. Monitoring of BCR-ABL transcript levels must beperformed with a quantitative diagnostic test validated to measure molecular response levels on the
International Scale (IS) with a sensitivity of at least MR4.5 (BCR-ABL/ABL ≤0.0032% IS).
For patients who lose MR4 (MR4=BCR-ABL/ABL ≤0.01%IS) but not MMR(MMR=BCR-ABL/ABL ≤0.1%IS) during the treatment-free phase, BCR-ABL transcript levels shouldbe monitored every 2 weeks until BCR-ABL levels return to a range between MR4 and MR4.5.
Patients who maintain BCR-ABL levels between MMR and MR4 for a minimum of 4 consecutivemeasurements can return to the original monitoring schedule.
Patients who lose MMR must re-initiate treatment within 4 weeks of when loss of remission is knownto have occurred. Nilotinib therapy should be re-initiated at 300 mg twice daily or at a reduced doselevel of 400 mg once daily if the patient had a dose reduction prior to discontinuation of therapy.
Patients who re-initiate nilotinib therapy should have their BCR-ABL transcript levels monitoredmonthly until MMR is re-established and every 12 weeks thereafter (see section 4.4).
Adult Philadelphia chromosome positive CML patients in chronic phase who have achieved asustained deep molecular response (MR 4.5) on nilotinib following prior imatinib therapy
Discontinuation of treatment may be considered in eligible adult Philadelphia chromosome positive(Ph+) CML patients in chronic phase who have been treated with nilotinib for a minimum of 3 years ifa deep molecular response is sustained for a minimum of one year immediately prior todiscontinuation of therapy. Discontinuation of nilotinib therapy should be initiated by a physicianexperienced in the treatment of patients with CML (see sections 4.4 and 5.1).
Eligible patients who discontinue nilotinib therapy must have their BCR-ABL transcript levels andcomplete blood count with differential monitored monthly for one year, then every 6 weeks for thesecond year, and every 12 weeks thereafter. Monitoring of BCR-ABL transcript levels must beperformed with a quantitative diagnostic test validated to measure molecular response levels on the
International Scale (IS) with a sensitivity of at least MR4.5 (BCR-ABL/ABL ≤0.0032% IS).
Patients with confirmed loss of MR4 (MR4= BCR-ABL/ABL ≤0.01%IS) during the treatment-freephase (two consecutive measures separated by at least 4 weeks showing loss of MR4) or loss of majormolecular response (MMR=BCR-ABL/ABL ≤0.1%IS) must re-initiate treatment within 4 weeks ofwhen loss of remission is known to have occurred. Nilotinib therapy should be re-initiated at either300 mg or 400 mg twice daily. Patients who re-initiate nilotinib therapy should have their BCR-ABLtranscript levels monitored monthly until previous major molecular response or MR4 level isre-established and every 12 weeks thereafter (see section 4.4).
Dose adjustments or modifications
Tasigna may need to be temporarily withheld and/or dose reduced for haematological toxicities(neutropenia, thrombocytopenia) that are not related to the underlying leukaemia (see Table 2).

*ANC = absolute neutrophil count
If clinically significant moderate or severe non-haematological toxicity develops, dosing should beinterrupted, and patients should be monitored and treated accordingly. If the prior dose was 300 mgtwice daily in adult newly diagnosed patients with CML in the chronic phase, or 400 mg twice daily inadult patients with imatinib-resistant or intolerant CML in chronic or accelerated phase, or 230 mg/m2twice daily in paediatric patients, dosing may be resumed at 400 mg once daily in adult patients and at230 mg/m2 once daily in paediatric patients once the toxicity has resolved. If the prior dose was400 mg once daily in adult patients or 230 mg/m2 once daily in paediatric patients, treatment should bediscontinued. If clinically appropriate, re-escalation of the dose to the starting dose of 300 mg twicedaily in adult newly diagnosed patients with CML in the chronic phase or to 400 mg twice daily inadult patients with imatinib-resistant or intolerant CML in chronic or accelerated phase or to230 mg/m2 twice daily in paediatric patients should be considered.
Elevated serum lipase: For Grade 3-4 serum lipase elevations, doses in adult patients should bereduced to 400 mg once daily or interrupted. In paediatric patients, treatment must be interrupted untilthe event returns to Grade 1. Thereafter, if the prior dose was 230 mg/m2 twice daily, treatment canbe resumed at 230 mg/m2 once daily. If the prior dose was 230 mg/m2 once daily, treatment should bediscontinued. Serum lipase levels should be tested monthly or as clinically indicated (see section 4.4).
Elevated bilirubin and hepatic transaminases: For Grade 3-4 bilirubin and hepatic transaminaseelevations in adult patients, doses should be reduced to 400 mg once daily or interrupted. For
Grade 2 bilirubin elevations or Grade 3 hepatic transaminase elevations in paediatric patients,treatment must be interrupted until the levels return to Grade 1. Thereafter, if the prior dose was230 mg/m2 twice daily, treatment can be resumed at 230 mg/m2 once daily. If the prior dose was230 mg/m2 once daily, and recovery to Grade 1 takes longer than 28 days, treatment should bediscontinued. Bilirubin and hepatic transaminases levels should be tested monthly or as clinicallyindicated.
Special populationsElderlyApproximately 12% of subjects in the Phase III study in patients with newly diagnosed CML inchronic phase and approximately 30% of subjects in the Phase II study in patients withimatinib-resistant or intolerant CML in chronic phase and accelerated phase were 65 years of age orover. No major differences were observed for safety and efficacy in patients ≥65 years of age ascompared to adults aged 18 to 65 years.
Renal impairmentClinical studies have not been performed in patients with impaired renal function.
Since nilotinib and its metabolites are not renally excreted, a decrease in total body clearance is notanticipated in patients with renal impairment.
Hepatic impairmentHepatic impairment has a modest effect on the pharmacokinetics of nilotinib. Dose adjustment is notconsidered necessary in patients with hepatic impairment. However, patients with hepatic impairmentshould be treated with caution (see section 4.4).
Cardiac disordersIn clinical studies, patients with uncontrolled or significant cardiac disease (e.g., recent myocardialinfarction, congestive heart failure, unstable angina or clinically significant bradycardia) wereexcluded. Caution should be exercised in patients with relevant cardiac disorders (see section 4.4).
Increases in total serum cholesterol levels have been reported with nilotinib therapy (see section 4.4).
Lipid profiles should be determined prior to initiating nilotinib therapy, assessed at month 3 and 6after initiating therapy and at least yearly during chronic therapy.
Increases in blood glucose levels have been reported with nilotinib therapy (see section 4.4). Bloodglucose levels should be assessed prior to initiating nilotinib therapy and monitored during treatment.
Paediatric populationThe safety and efficacy of Tasigna in paediatric patients with Philadelphia chromosome positive CMLin chronic phase from 2 to less than 18 years of age have been established (see sections 4.8, 5.1 and5.2). There is no experience in paediatric patients below 2 years of age or in paediatric patients with
Philadelphia chromosome positive CML in accelerated phase or blast crisis. There are no data innewly diagnosed paediatric patients below 10 years of age and limited data in imatinib-resistant orintolerant paediatric patients below 6 years of age.
Method of administrationTasigna should be taken twice daily approximately 12 hours apart and must not be taken with food.
The hard capsules should be swallowed whole with water. No food should be consumed for 2 hoursbefore the dose is taken and no food should be consumed for at least one hour after the dose is taken.
For patients who are unable to swallow hard capsules, the content of each hard capsule may bedispersed in one teaspoon of apple sauce (puréed apple) and should be taken immediately. Not morethan one teaspoon of apple sauce and no food other than apple sauce must be used (see sections 4.4and 5.2).
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
4.4 Special warnings and precautions for use
MyelosuppressionTreatment with nilotinib is associated with (National Cancer Institute Common Toxicity Criteriagrade 3 and 4) thrombocytopenia, neutropenia and anaemia. Occurrence is more frequent in patientswith imatinib-resistant or intolerant CML, in particular in patients with accelerated-phase CML.
Complete blood counts should be performed every two weeks for the first 2 months and then monthlythereafter, or as clinically indicated. Myelosuppression was generally reversible and usually managedby withholding Tasigna temporarily or dose reduction (see section 4.2).
QT prolongationNilotinib has been shown to prolong cardiac ventricular repolarisation as measured by the QT intervalon the surface ECG in a concentration-dependent manner in adult and paediatric patients.
In the Phase III study in patients with newly diagnosed CML in chronic phase receiving 300 mgnilotinib twice daily, the change from baseline in mean time-averaged QTcF interval at steady statewas 6 msec. No patient had a QTcF >480 msec. No episodes of torsade de pointes were observed.
In the Phase II study in imatinib-resistant and intolerant CML patients in chronic and acceleratedphase receiving 400 mg nilotinib twice daily, the change from baseline in mean time-averaged QTcFinterval at steady state was 5 and 8 msec, respectively. QTcF of >500 msec was observed in <1% ofthese patients. No episodes of torsade de pointes were observed in clinical studies.
In a healthy volunteer study with exposures that were comparable to the exposures observed inpatients, the time-averaged mean placebo-subtracted QTcF change from baseline was 7 msec(CI ± 4 msec). No subject had a QTcF >450 msec. Additionally, no clinically relevant arrhythmiaswere observed during the conduct of the trial. In particular, no episodes of torsade de pointes (transientor sustained) were observed.
Significant prolongation of the QT interval may occur when nilotinib is inappropriately taken withstrong CYP3A4 inhibitors and/or medicinal products with a known potential to prolong the QTinterval, and/or food (see section 4.5). The presence of hypokalaemia and hypomagnesaemia mayfurther enhance this effect. Prolongation of the QT interval may expose patients to the risk of fataloutcome.
Tasigna should be used with caution in patients who have or who are at significant risk of developingprolongation of QTc, such as those:
- with congenital long QT prolongation
- with uncontrolled or significant cardiac disease including recent myocardial infarction,congestive heart failure, unstable angina or clinically significant bradycardia.
- taking anti-arrhythmic medicinal products or other substances that lead to QT prolongation.
Close monitoring for an effect on the QTc interval is advisable and a baseline ECG is recommendedprior to initiating nilotinib therapy and as clinically indicated. Hypokalaemia or hypomagnesaemiamust be corrected prior to Tasigna administration and should be monitored periodically duringtherapy.
Sudden death
Uncommon cases (0.1 to 1%) of sudden deaths have been reported in patients with imatinib-resistantor intolerant CML in chronic phase or accelerated phase with a past medical history of cardiac diseaseor significant cardiac risk factors. Co-morbidities in addition to the underlying malignancy were alsofrequently present as were concomitant medicinal products. Ventricular repolarisation abnormalitiesmay have been contributory factors. No cases of sudden death were reported in the Phase III study innewly diagnosed patients with CML in chronic phase.
Fluid retention and oedema
Severe forms of drug-related fluid retention such as pleural effusion, pulmonary oedema, andpericardial effusion were uncommonly (0.1 to 1%) observed in a Phase III study of newly diagnosed
CML patients. Similar events were observed in post-marketing reports. Unexpected, rapid weight gainshould be carefully investigated. If signs of severe fluid retention appear during treatment withnilotinib, the aetiology should be evaluated and patients treated accordingly (see section 4.2 forinstructions on managing non-haematological toxicities).
Cardiovascular eventsCardiovascular events were reported in a randomised Phase III study in newly diagnosed CMLpatients and observed in post-marketing reports. In this clinical study with a median on-therapy timeof 60.5 months, Grade 3-4 cardiovascular events included peripheral arterial occlusive disease (1.4%and 1.1% at 300 mg and 400 mg nilotinib twice daily, respectively), ischaemic heart disease (2.2% and6.1% at 300 mg and 400 mg nilotinib twice daily, respectively) and ischaemic cerebrovascular events(1.1% and 2.2% at 300 mg and 400 mg nilotinib twice daily, respectively). Patients should be advisedto seek immediate medical attention if they experience acute signs or symptoms of cardiovascularevents. The cardiovascular status of patients should be evaluated and cardiovascular risk factorsmonitored and actively managed during nilotinib therapy according to standard guidelines.
Appropriate therapy should be prescribed to manage cardiovascular risk factors (see section 4.2 forinstructions on managing non-haematological toxicities).
Hepatitis B reactivationReactivation of hepatitis B in patients who are chronic carriers of this virus has occurred after thesepatients received BCR-ABL tyrosine kinase inhibitors. Some cases resulted in acute hepatic failure orfulminant hepatitis leading to liver transplantation or a fatal outcome.
Patients should be tested for HBV infection before initiating treatment with nilotinib. Experts in liverdisease and in the treatment of hepatitis B should be consulted before treatment is initiated in patientswith positive hepatitis B serology (including those with active disease) and for patients who testpositive for HBV infection during treatment. Carriers of HBV who require treatment with nilotinibshould be closely monitored for signs and symptoms of active HBV infection throughout therapy andfor several months following termination of therapy (see section 4.8).
Special monitoring of adult Ph+ CML patients in chronic phase who have achieved a sustained deepmolecular response
Eligibility for discontinuation of treatment
Eligible patients who are confirmed to express the typical BCR-ABL transcripts, e13a2/b2a2 ore14a2/b3a2, can be considered for treatment discontinuation. Patients must have typical BCR-ABLtranscripts to allow quantitation of BCR-ABL, evaluation of the depth of molecular response, anddetermination of a possible loss of molecular remission after discontinuation of treatment withnilotinib.
Monitoring of patients who have discontinued therapy
Frequent monitoring of BCR-ABL transcript levels in patients eligible for treatment discontinuationmust be performed with a quantitative diagnostic test validated to measure molecular response levelswith a sensitivity of at least MR4.5 (BCR-ABL/ABL ≤0.0032% IS). BCR-ABL transcript levels mustbe assessed prior to and during treatment discontinuation (see sections 4.2 and 5.1).
Loss of major molecular response (MMR=BCR-ABL/ABL ≤0.1%IS) in CML patients who receivednilotinib as first- or second-line therapy, or confirmed loss of MR4 (two consecutive measuresseparated by at least 4 weeks showing loss of MR4 (MR4=BCR-ABL/ABL ≤0.01%IS)) in CMLpatients who received nilotinib as second-line therapy will trigger treatment re-initiation within4 weeks of when loss of remission is known to have occurred. Molecular relapse can occur during thetreatment-free phase, and long-term outcome data are not yet available. It is therefore crucial toperform frequent monitoring of BCR-ABL transcript levels and complete blood count with differentialin order to detect possible loss of remission (see section 4.2). For patients who fail to achieve MMRafter three months of treatment re-initiation, BCR-ABL kinase domain mutation testing should beperformed.
Laboratory tests and monitoring
Blood lipids
In a Phase III study in newly diagnosed CML patients, 1.1% of the patients treated with 400 mgnilotinib twice daily showed a Grade 3-4 elevation in total cholesterol; no Grade 3-4 elevations werehowever observed in the 300 mg twice daily dose group (see section 4.8). It is recommended that thelipid profiles be determined before initiating treatment with nilotinib, assessed at month 3 and 6 afterinitiating therapy and at least yearly during chronic therapy (see section 4.2). If a HMG-CoA reductaseinhibitor (a lipid-lowering agent) is required, please refer to section 4.5 before initiating treatmentsince certain HMG-CoA reductase inhibitors are also metabolised by the CYP3A4 pathway.
Blood glucose
In a Phase III study in newly diagnosed CML patients, 6.9% and 7.2% of the patients treated with400 mg nilotinib and 300 mg nilotinib twice daily, respectively, showed a Grade 3-4 elevation inblood glucose. It is recommended that the glucose levels be assessed before initiating treatment with
Tasigna and monitored during treatment, as clinically indicated (see section 4.2). If test results warranttherapy, physicians should follow their local standards of practice and treatment guidelines.
Interactions with other medicinal productsThe administration of Tasigna with agents that are strong CYP3A4 inhibitors (including, but notlimited to, ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, ritonavir) shouldbe avoided. Should treatment with any of these agents be required, it is recommended that nilotinibtherapy be interrupted if possible (see section 4.5). If transient interruption of treatment is not possible,close monitoring of the individual for prolongation of the QT interval is indicated (see sections 4.2,4.5 and 5.2).
Concomitant use of nilotinib with medicinal products that are potent inducers of CYP3A4 (e.g.,phenytoin, rifampicin, carbamazepine, phenobarbital and St. John’s Wort) is likely to reduce exposureto nilotinib to a clinically relevant extent. Therefore, in patients receiving nilotinib, co-administrationof alternative therapeutic agents with less potential for CYP3A4 induction should be selected (seesection 4.5).
Food effectThe bioavailability of nilotinib is increased by food. Tasigna must not be taken in conjunction withfood (see sections 4.2 and 4.5) and should be taken 2 hours after a meal. No food should be consumedfor at least one hour after the dose is taken. Grapefruit juice and other foods that are known to inhibit
CYP3A4 should be avoided. For patients who are unable to swallow hard capsules, the content of eachhard capsule may be dispersed in one teaspoon of apple sauce and should be taken immediately. Notmore than one teaspoon of apple sauce and no food other than apple sauce must be used (seesection 5.2).
Hepatic impairmentHepatic impairment has a modest effect on the pharmacokinetics of nilotinib. Single doseadministration of 200 mg of nilotinib resulted in increases in AUC of 35%, 35% and 19% in subjectswith mild, moderate and severe hepatic impairment, respectively, compared to a control group ofsubjects with normal hepatic function. The predicted steady-state Cmax of nilotinib showed an increaseof 29%, 18% and 22%, respectively. Clinical studies have excluded patients with alanine transaminase(ALT) and/or aspartate transaminase (AST) >2.5 (or >5, if related to disease) times the upper limit ofthe normal range and/or total bilirubin >1.5 times the upper limit of the normal range. Metabolism ofnilotinib is mainly hepatic. Patients with hepatic impairment might therefore have increased exposureto nilotinib and should be treated with caution (see section 4.2).
Serum lipase
Elevation in serum lipase has been observed. Caution is recommended in patients with previoushistory of pancreatitis. In case lipase elevations are accompanied by abdominal symptoms, nilotinibtherapy should be interrupted and appropriate diagnostic measures considered to exclude pancreatitis.
Total gastrectomy
The bioavailability of nilotinib might be reduced in patients with total gastrectomy (see section 5.2).
More frequent follow-up of these patients should be considered.
Tumour lysis syndromeDue to possible occurrence of tumour lysis syndrome (TLS) correction of clinically significantdehydration and treatment of high uric acid levels are recommended prior to initiating nilotinibtherapy (see section 4.8).
LactoseTasigna hard capsules contain lactose. Patients with rare hereditary problems of galactose intolerance,the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicinal product.
Paediatric populationLaboratory abnormalities of mild to moderate transient elevations of aminotransferases and totalbilirubin have been observed in children at a higher frequency than in adults, indicating a higher riskof hepatotoxicity in the paediatric population (see section 4.8). Liver function (bilirubin and hepatictransaminases levels) should be monitored monthly or as clinically indicated. Elevations of bilirubinand hepatic transaminases should be managed by withholding nilotinib temporarily, dose reductionand/or discontinuation of nilotinib (see section 4.2). In a study in the CML paediatric population,growth retardation has been documented in patients treated with nilotinib (see section 4.8). Closemonitoring of growth in paediatric patients under nilotinib treatment is recommended.
4.5 Interaction with other medicinal products and other forms of interaction
Tasigna may be given in combination with haematopoietic growth factors such as erythropoietin orgranulocyte colony-stimulating factor (G-CSF) if clinically indicated. It may be given withhydroxyurea or anagrelide if clinically indicated.
Nilotinib is mainly metabolised in the liver with CYP3A4 expected to be the main contributor to theoxidative metabolism. Nilotinib is also a substrate for the multi-drug efflux pump, P-glycoprotein(P-gp). Therefore, absorption and subsequent elimination of systemically absorbed nilotinib may beinfluenced by substances that affect CYP3A4 and/or P-gp.
Substances that may increase nilotinib serum concentrations
Concomitant administration of nilotinib with imatinib (a substrate and moderator of P-gp and
CYP3A4), had a slight inhibitory effect on CYP3A4 and/or P-gp. The AUC of imatinib was increasedby 18% to 39%, and the AUC of nilotinib was increased by 18% to 40%. These changes are unlikelyto be clinically important.
The exposure to nilotinib in healthy subjects was increased 3-fold when co-administered with thestrong CYP3A4 inhibitor ketoconazole. Concomitant treatment with strong CYP3A4 inhibitors,including ketoconazole, itraconazole, voriconazole, ritonavir, clarithromycin, and telithromycin,should therefore be avoided (see section 4.4). Increased exposure to nilotinib might also be expectedwith moderate CYP3A4 inhibitors. Alternative concomitant medicinal products with no or minimal
CYP3A4 inhibition should be considered.
Substances that may decrease nilotinib serum concentrations
Rifampicin, a potent CYP3A4 inducer, decreases nilotinib Cmax by 64% and reduces nilotinib AUC by80%. Rifampicin and nilotinib should not be used concomitantly.
The concomitant administration of other medicinal products that induce CYP3A4 (e.g. phenytoin,carbamazepine, phenobarbital and St. John’s Wort) is likewise likely to reduce exposure to nilotinib toa clinically relevant extent. In patients for whom CYP3A4 inducers are indicated, alternative agentswith less enzyme induction potential should be selected.
Nilotinib has pH dependent solubility, with lower solubility at higher pH. In healthy subjects receivingesomeprazole at 40 mg once daily for 5 days, gastric pH was markedly increased, but nilotinibabsorption was only decreased modestly (27% decrease in Cmax and 34% decrease in AUC0-∞).
Nilotinib may be used concurrently with esomeprazole or other proton pump inhibitors as needed.
In a study in healthy subjects, no significant change in nilotinib pharmacokinetics was observed whena single 400 mg dose of nilotinib was administered 10 hours after and 2 hours before famotidine.
Therefore, when the concurrent use of a H2 blocker is necessary, it may be administeredapproximately 10 hours before and approximately 2 hours after the dose of Tasigna.
In the same study as above, administration of an antacid (aluminium hydroxide/magnesiumhydroxide/simethicone) 2 hours before or after a single 400 mg dose of nilotinib also did not alternilotinib pharmacokinetics. Therefore, if necessary, an antacid may be administered approximately2 hours before or approximately 2 hours after the dose of Tasigna.
Substances that may have their systemic concentration altered by nilotinib
In vitro, nilotinib is a relatively strong inhibitor of CYP3A4, CYP2C8, CYP2C9, CYP2D6 and
UGT1A1, with Ki value being lowest for CYP2C9 (Ki=0.13 microM).
A single-dose drug-drug interaction study in healthy volunteers with 25 mg warfarin, a sensitive
CYP2C9 substrate, and 800 mg nilotinib did not result in any changes in warfarin pharmacokineticparameters or warfarin pharmacodynamics measured as prothrombin time (PT) and internationalnormalised ratio (INR). There are no steady-state data. This study suggests that a clinically meaningfuldrug-drug interaction between nilotinib and warfarin is less likely up to a dose of 25 mg of warfarin.
Due to lack of steady-state data, control of warfarin pharmacodynamic markers (INR or PT) followinginitiation of nilotinib therapy (at least during the first 2 weeks) is recommended.
In CML patients, nilotinib administered at 400 mg twice daily for 12 days increased the systemicexposure (AUC and Cmax) of oral midazolam (a substrate of CYP3A4) 2.6-fold and 2.0-fold,respectively. Nilotinib is a moderate CYP3A4 inhibitor. As a result, the systemic exposure of othermedicinal products primarily metabolised by CYP3A4 (e.g. certain HMG-CoA reductase inhibitors)may be increased when co-administered with nilotinib. Appropriate monitoring and dose adjustmentmay be necessary for medicinal products that are CYP3A4 substrates and have a narrow therapeuticindex (including but not limited to alfentanil, cyclosporine, dihydroergotamine, ergotamine, fentanyl,sirolimus and tacrolimus) when co-administered with nilotinib.
The combination of nilotinib with those statins that are mainly eliminated by CYP3A4, may increasethe potential for statin-induced myopathy, including rhabdomyolysis.
Anti-arrhythmic medicinal products and other substances that may prolong the QT interval
Nilotinib should be used with caution in patients who have or may develop prolongation of the QTinterval, including those patients taking anti-arrhythmic medicinal products such as amiodarone,disopyramide, procainamide, quinidine and sotalol or other medicinal products that may lead to QTprolongation such as chloroquine, halofantrine, clarithromycin, haloperidol, methadone andmoxifloxacin (see section 4.4).
Food interactionsThe absorption and bioavailability of nilotinib are increased if it is taken with food, resulting in ahigher serum concentration (see sections 4.2, pct. 4.4 and 5.2). Grapefruit juice and other foods that areknown to inhibit CYP3A4 should be avoided.
Paediatric populationInteraction studies have only been performed in adults.

Women of childbearing potential/ContraceptionWomen of childbearing potential have to use highly effective contraception during treatment withnilotinib and for up to two weeks after ending treatment.
PregnancyThere are no or limited amount of data from the use of nilotinib in pregnant women. Studies inanimals have shown reproductive toxicity (see section 5.3). Tasigna should not be used duringpregnancy unless the clinical condition of the woman requires treatment with nilotinib. If it is usedduring pregnancy, the patient must be informed of the potential risk to the foetus.
If a woman who is being treated with nilotinib is considering pregnancy, treatment discontinuationmay be considered based on the eligibility criteria for discontinuing treatment as described insections 4.2 and 4.4. There is a limited amount of data on pregnancies in patients while attemptingtreatment-free remission (TFR). If pregnancy is planned during the TFR phase, the patient must beinformed of a potential need to re-initiate nilotinib treatment during pregnancy (see sections 4.2 and4.4).
Breast-feedingIt is unknown whether nilotinib is excreted in human milk. Available toxicological data in animalshave shown excretion of nilotinib in milk (see section 5.3). Since a risk to the newborns/infants cannotbe excluded, women should not breast-feed during Tasigna treatment and for 2 weeks after the lastdose.
FertilityAnimal studies did not show an effect on fertility in male and female rats (see section 5.3).
4.7 Effects on ability to drive and use machines
Tasigna has no or negligible influence on the ability to drive and use machines. However, it isrecommended that patients experiencing dizziness, fatigue, visual impairment or other undesirableeffects with a potential impact on the ability to drive or use machines safely should refrain from theseactivities as long as the undesirable effects persist (see section 4.8).
4.8 Undesirable effects
Summary of the safety profileThe safety profile is based on pooled data from 3,422 patients treated with Tasigna in 13 clinicalstudies in the approved indications: adults and paediatric patients with newly diagnosed Philadelphiachromosome positive chronic myelogenous leukaemia (CML) in the chronic phase (5 clinical studieswith 2,414 patients), adult patients with chronic phase and accelerated phase Philadelphiachromosome positive CML with resistance or intolerance to prior therapy including imatinib(6 clinical studies with 939 patients) and paediatric patients with chronic phase Philadelphiachromosome positive CML with resistance or intolerance to prior therapy including imatinib(2 clinical studies with 69 patients). These pooled data represents 9,039.34 patient-years of exposure.
The safety profile of nilotinib is consistent across indications.
The most common adverse reactions (incidence ≥15%) from the pooled safety data were: rash(26.4%), upper respiratory tract infection (including pharyngitis, nasopharyngitis, rhinitis) (24.8%)headache (21.9%), hyperbilirubinaemia (including blood bilirubin increased) (18.6%), arthralgia(15.8%), fatigue (15.4%), nausea (16.8%), pruritus (16.7%) and thrombocytopenia (16.4%).

Description of selected adverse reactionsSudden death
Uncommon cases (0.1 to 1%) of sudden deaths have been reported in Tasigna clinical studies and/orcompassionate use programs in patients with imatinib -resistant or intolerant CML in chronic phase oraccelerated phase with a past medical history of cardiac disease or significant cardiac risk factors (seesection 4.4).
Hepatitis B reactivationHepatitis B reactivation has been reported in association with BCR-ABL TKIs. Some cases resulted inacute hepatic failure or fulminant hepatitis leading to liver transplantation or a fatal outcome (seesection 4.4).
Paediatric populationThe safety of nilotinib in paediatric patients (from 2 to <18 years of age) with Philadelphiachromosome positive CML in chronic phase (n=58) has been investigated in one main study over aperiod of 60 months (see section 5.1). In paediatric patients, the frequency, type and severity ofadverse reactions observed have been generally consistent with those observed in adults, with theexception of hyperbilirubinaemia/blood bilirubin increase (Grade 3/4: 10.3%) and transaminaseelevation (AST Grade 3/4: 1.7%, ALT Grade 3/4: 12.1%) which were reported at a higher frequencythan in adult patients. Bilirubin and hepatic transaminase levels should be monitored during treatment(see sections 4.2 and 4.4).
Growth retardation in paediatric population
In a study conducted in the CML paediatric population, with a median exposure of 51.9 months innewly diagnosed patients and 59.9 months in imatinib/dasatinib-resistant or imatinib-intolerant Ph+
CML-CP patients, growth deceleration (crossing at least two main percentile lines from baseline) wasobserved in eight patients: five (8.6%) crossed two main percentile lines from baseline and three(5.2%) crossed three main percentile lines from baseline. Growth retardation related events werereported in 3 patients (5.2%). Close monitoring of growth in paediatric patients under nilotinibtreatment is recommended (see section 4.4).
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
4.9 Overdose
Isolated reports of intentional overdose with nilotinib were reported, where an unspecified number of
Tasigna hard capsules were ingested in combination with alcohol and other medicinal products. Eventsincluded neutropenia, vomiting and drowsiness. No ECG changes or hepatotoxicity were reported.
Outcomes were reported as recovered.
In the event of overdose, the patient should be observed and appropriate supportive treatment given.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antineoplastic agents, BCR-ABL tyrosine kinase inhibitors, ATCcode: L01EA03.
Mechanism of actionNilotinib is a potent inhibitor of the ABL tyrosine kinase activity of the BCR-ABL oncoprotein both incell lines and in primary Philadelphia-chromosome positive leukaemia cells. The substance binds withhigh affinity to the ATP-binding site in such a manner that it is a potent inhibitor of wild-type
BCR-ABL and maintains activity against 32/33 imatinib-resistant mutant forms of BCR-ABL. As aconsequence of this biochemical activity, nilotinib selectively inhibits the proliferation and inducesapoptosis in cell lines and in primary Philadelphia-chromosome positive leukaemia cells from CMLpatients. In murine models of CML, as a single agent nilotinib reduces tumour burden and prolongssurvival following oral administration.
Pharmacodynamic effectsNilotinib has little or no effect against the majority of other protein kinases examined, including Src,except for the PDGF, KIT and Ephrin receptor kinases, which it inhibits at concentrations within therange achieved following oral administration at therapeutic doses recommended for the treatment of
CML (see Table 4).

Clinical efficacyClinical studies in newly diagnosed CML in chronic phase
An open-label, multicentre, randomised Phase III study was conducted to determine the efficacy ofnilotinib versus imatinib in 846 adult patients with cytogenetically confirmed newly diagnosed
Philadelphia chromosome positive CML in the chronic phase. Patients were within six months ofdiagnosis and were previously untreated, with the exception of hydroxyurea and/or anagrelide.
Patients were randomised 1:1:1 to receive either nilotinib 300 mg twice daily (n=282), nilotinib400 mg twice daily (n=281) or imatinib 400 mg once daily (n=283). Randomisation was stratified by
Sokal risk score at the time of diagnosis.
Baseline characteristics were well balanced between the three treatment arms. Median age was47 years in both nilotinib arms and 46 years in the imatinib arm, with 12.8%, 10.0% and 12.4% ofpatients were ≥65 years of age in the nilotinib 300 mg twice daily, nilotinib 400 mg twice daily andimatinib 400 mg once daily treatment arms, respectively. There were slightly more male than femalepatients (56.0%, 62.3% and 55.8%, in the nilotinib 300 mg twice daily, 400 mg twice daily andimatinib 400 mg once daily arm, respectively). More than 60% of all patients were Caucasian and 25%of all patients were Asian.
The primary data analysis time point was when all 846 patients completed 12 months of treatment (ordiscontinued earlier). Subsequent analyses reflect when patients completed 24, 36, 48, 60 and72 months of treatment (or discontinued earlier). The median time on treatment was approximately70 months in the nilotinib treatment groups and 64 months in the imatinib group. The median actualdose intensity was 593 mg/day for nilotinib 300 mg twice daily, 772 mg/day for nilotinib 400 mgtwice daily and 400 mg/day for imatinib 400 mg once daily. This study is ongoing.
The primary efficacy endpoint was major molecular response (MMR) at 12 months. MMR wasdefined as ≤0.1% BCR-ABL/ABL% by international scale (IS) measured by RQ-PCR, whichcorresponds to a ≥3 log reduction of BCR-ABL transcript from standardised baseline. The MMR rateat 12 months was statistically significantly higher for nilotinib 300 mg twice daily compared toimatinib 400 mg once daily (44.3% versus 22.3%, p<0.0001). The rate of MMR at 12 months, wasalso statistically significantly higher for nilotinib 400 mg twice daily compared to imatinib 400 mgonce daily (42.7% versus 22.3%, p<0.0001).
The rates of MMR at 3, 6, 9 and 12 months were 8.9%, 33.0%, 43.3% and 44.3% for nilotinib 300 mgtwice daily, 5.0%, 29.5%, 38.1% and 42.7% for nilotinib 400 mg twice daily and 0.7%, 12.0%, 18.0%and 22.3% for imatinib 400 mg once daily.
The MMR rate at 12, 24, 36, 48, 60 and 72 months is presented in Table 5.

Months since randomisation
For all Sokal risk groups, the MMR rates at all time points remained consistently higher in the twonilotinib groups than in the imatinib group.
In a retrospective analysis, 91% (234/258) of patients on nilotinib 300 mg twice daily achieved
BCR-ABL levels ≤10% at 3 months of treatment compared to 67% (176/264) of patients on imatinib400 mg once daily. Patients with BCR-ABL levels ≤10% at 3 months of treatment show a greateroverall survival at 72 months compared to those who did not achieve this molecular response level(94.5% vs. 77.1% respectively [p=0.0005]).
Based on the Kaplan-Meier analysis of time to first MMR the probability of achieving MMR atdifferent time points was higher for both nilotinib at 300 mg and 400 mg twice daily compared toimatinib 400 mg once daily (HR=2.17 and stratified log-rank p<0.0001 between nilotinib 300 mgtwice daily and imatinib 400 mg once daily, HR=1.88 and stratified log-rank p<0.0001 betweennilotinib 400 mg twice daily and imatinib 400 mg once daily).
The proportion of patients who had a molecular response of ≤0.01% and ≤0.0032% by IS at differenttime points are presented in Table 6 and the proportion of patients who had a molecular response of≤0.01% and ≤0.0032% by IS by different time points are presented in Figures 2 and 3. Molecularresponses of ≤0.01% and ≤0.0032% by IS correspond to a ≥4 log reduction and ≥4.5 log reduction,respectively, of BCR-ABL transcripts from a standardised baseline.

Based on Kaplan-Meier estimates of the duration of first MMR, the proportions of patients who weremaintaining response for 72 months among patients who achieved MMR were 92.5% (95% CI:
88.6-96.4%) in the nilotinib 300 mg twice daily group, 92.2% (95% CI: 88.5-95.9%) in the nilotinib400 mg twice daily group and 88.0% (95% CI: 83.0-93.1%) in the imatinib 400 mg once daily group.
Complete cytogenetic response (CCyR) was defined as 0% Ph+ metaphases in the bone marrow basedon a minimum of 20 metaphases evaluated. Best CCyR rate by 12 months (including patients whoachieved CCyR at or before the 12 month time point as responders) was statistically higher for bothnilotinib 300 mg and 400 mg twice daily compared to imatinib 400 mg once daily, see Table 7.
CCyR rate by 24 months (includes patients who achieved CCyR at or before the 24 month time pointas responders) was statistically higher for both the nilotinib 300 mg twice daily and 400 mg twicedaily groups compared to the imatinib 400 mg once daily group.

Progression to accelerated phase (AP) or blast crisis (BC) on treatment is defined as the time from thedate of randomisation to the first documented disease progression to accelerated phase or blast crisisor CML-related death. Progression to accelerated phase or blast crisis on treatment was observed in atotal of 17 patients: 2 patients on nilotinib 300 mg twice daily, 3 patients on nilotinib 400 mg twicedaily and 12 patients on imatinib 400 mg once daily. The estimated rates of patients free fromprogression to accelerated phase or blast crisis at 72 months were 99.3%, 98.7% and 95.2%,respectively (HR=0.1599 and stratified log-rank p=0.0059 between nilotinib 300 mg twice daily andimatinib once daily, HR=0.2457 and stratified log-rank p=0.0185 between nilotinib 400 mg twicedaily and imatinib once daily). No new events of progression to AP/BC were reported on-treatmentsince the 2-year analysis.
Including clonal evolution as a criterion for progression, a total of 25 patients progressed toaccelerated phase or blast crisis on treatment by the cut-off date (3 in the nilotinib 300 mg twice dailygroup, 5 in the nilotinib 400 mg twice daily group and 17 in the imatinib 400 mg once daily group).
The estimated rates of patients free from progression to accelerated phase or blast crisis includingclonal evolution at 72 months were 98.7%, 97.9% and 93.2%, respectively (HR=0.1626 and stratifiedlog-rank p=0.0009 between nilotinib 300 mg twice daily and imatinib once daily, HR=0.2848 andstratified log-rank p=0.0085 between nilotinib 400 mg twice daily and imatinib once daily).
A total of 55 patients died during treatment or during the follow-up after discontinuation of treatment(21 in the nilotinib 300 mg twice daily group, 11 in the nilotinib 400 mg twice daily group and 23 inthe imatinib 400 mg once daily group). Twenty-six (26) of these 55 deaths were related to CML (6 inthe nilotinib 300 mg twice daily group, 4 in the nilotinib 400 mg twice daily group and 16 in theimatinib 400 mg once daily group). The estimated rates of patients alive at 72 months were 91.6%,95.8% and 91.4%, respectively (HR=0.8934 and stratified log-rank p=0.7085 between nilotinib300 mg twice daily and imatinib, HR=0.4632 and stratified log-rank p=0.0314 between nilotinib400 mg twice daily and imatinib). Considering only CML-related deaths as events, the estimated ratesof overall survival at 72 months were 97.7%, 98.5% and 93.9%, respectively (HR=0.3694 andstratified log-rank p=0.0302 between nilotinib 300 mg twice daily and imatinib, HR=0.2433 andstratified log-rank p=0.0061 between nilotinib 400 mg twice daily and imatinib).
Clinical studies in imatinib-resistant or intolerant CML in chronic phase and accelerated phase
An open-label, uncontrolled, multicentre Phase II study was conducted to determine the efficacy ofnilotinib in adult patients with imatinib resistant or intolerant CML with separate treatment arms forchronic and accelerated phase disease. Efficacy was based on 321 CP patients and 137 AP patientsenrolled. Median duration of treatment was 561 days for CP patients and 264 days for AP patients (see
Table 8). Tasigna was administered on a continuous basis (twice daily 2 hours after a meal and withno food for at least one hour after administration) unless there was evidence of inadequate response ordisease progression. The dose was 400 mg twice daily and dose escalation to 600 mg twice daily wasallowed.

Chronic phase Accelerated phasen=321 n=137
Median duration of therapy in days 561 264(25th-75th percentiles) (196-852) (115-595)
Resistance to imatinib included failure to achieve a complete haematological response (by 3 months),cytogenetic response (by 6 months) or major cytogenetic response (by 12 months) or progression ofdisease after a previous cytogenetic or haematological response. Imatinib intolerance included patientswho discontinued imatinib because of toxicity and were not in major cytogenetic response at time ofstudy entry.
Overall, 73% of patients were imatinib-resistant, while 27% were imatinib-intolerant. The majority ofpatients had a long history of CML that included extensive prior treatment with other antineoplasticagents, including imatinib, hydroxyurea, interferon, and some had even failed organ transplant(Table 9). The median highest prior imatinib dose had been 600 mg/day. The highest prior imatinibdose was 600 mg/day in 74% of all patients, with 40% of patients receiving imatinib doses800 mg/day.

The primary endpoint in the CP patients was major cytogenetic response (MCyR), defined aselimination (CCyR, complete cytogenetic response) or significant reduction to <35% Ph+ metaphases(partial cytogenetic response) of Ph+ haematopoietic cells. Complete haematological response (CHR)in CP patients was evaluated as a secondary endpoint. The primary endpoint in the AP patients wasoverall confirmed haematological response (HR), defined as either a complete haematologicalresponse, no evidence of leukaemia or return to chronic phase.
Chronic phase
The MCyR rate in 321 CP patients was 51%. Most responders achieved their MCyR rapidly within3 months (median 2.8 months) of starting nilotinib treatment and these were sustained. The mediantime to achieve CCyR was just past 3 months (median 3.4 months). Of the patients who achieved
MCyR, 77% (95% CI: 70% - 84%) were maintaining response at 24 months. Median duration of
MCyR has not been reached. Of the patients who achieved CCyR, 85% (95% CI: 78% - 93%) weremaintaining response at 24 months. Median duration of CCyR has not been reached. Patients with a
CHR at baseline achieved a MCyR faster (1.9 versus 2.8 months). Of CP patients without a baseline
CHR, 70% achieved a CHR, median time to CHR was 1 month and median duration of CHR was32.8 months. The estimated 24-month overall survival rate in CML-CP patients was 87%.
Accelerated phase
The overall confirmed HR rate in 137 AP patients was 50%. Most responders achieved a HR earlywith nilotinib treatment (median 1.0 months) and these have been durable (median duration ofconfirmed HR was 24.2 months). Of the patients who achieved HR, 53% (95% CI: 39% - 67%) weremaintaining response at 24 months. MCyR rate was 30% with a median time to response of2.8 months. Of the patients who achieved MCyR, 63% (95% CI: 45% - 80%) were maintainingresponse at 24 months. Median duration of MCyR was 32.7 months. The estimated 24-month overallsurvival rate in CML-AP patients was 70%.
The rates of response for the two treatment arms are reported in Table 10.

Efficacy data in patients with CML-BC are not yet available. Separate treatment arms were alsoincluded in the Phase II study to investigate Tasigna in a group of CP and AP patients who had beenextensively pre-treated with multiple therapies including a tyrosine kinase inhibitor agent in additionto imatinib. Of these patients 30/36 (83%) were treatment resistant not intolerant. In 22 CP patientsevaluated for efficacy nilotinib induced a 32% MCyR rate and a 50% CHR rate. In 11 AP patients,evaluated for efficacy, treatment induced a 36% overall HR rate.
After imatinib failure, 24 different BCR-ABL mutations were noted in 42% of chronic phase and 54%of accelerated phase CML patients who were evaluated for mutations. Tasigna demonstrated efficacyin patients harboring a variety of BCR-ABL mutations associated with imatinib resistance, except
T315I.
Treatment discontinuation in adult Ph+ CML patients in chronic phase who have been treated withnilotinib as first-line therapy and who have achieved a sustained deep molecular response
In an open-label, single-arm study, 215 adult patients with Ph+ CML in chronic phase treated withnilotinib in first-line for ≥2 years who achieved MR4.5 as measured with the MolecularMD MRDx
BCR-ABL test were enrolled to continue nilotinib treatment for additional 52 weeks (nilotinibconsolidation phase). 190 of 215 patients (88.4%) entered the TFR phase after achieving a sustaineddeep molecular response during the consolidation phase, defined by the following criteria:
- the 4 last quarterly assessments (taken every 12 weeks) were at least MR4.0 (BCR-ABL/ABL≤0.01% IS), and maintained for one year
- the last assessment being MR4.5 (BCR-ABL/ABL ≤0.0032% IS)
- no more than two assessments falling between MR4.0 and MR4.5(0.0032% IS < BCR-ABL/ABL ≤0.01% IS).
The primary endpoint was the percentage of patients in MMR at 48 weeks after starting the TFR phase(considering any patient who required re-initiation of treatment as non-responder).

[2] For 2 patients, PCR assessment was not available at week 264 therefore their response was notconsidered for the week 264 data cut-off analysis.
The time by which 50% of all retreated patients regained MMR and MR4.5 was 7 and 12.9 weeks,respectively. The cumulative rate of MMR regained at 24 weeks after treatment re-initiation was97.8% (89/91 patients) and MR4.5 regained at 48 weeks was 91.2% (83/91 patients).
The Kaplan-Meier estimate of median treatment-free survival (TFS) was 120.1 weeks (95% CI: 36.9,not estimable [NE]) (Figure 4); 91 of 190 patients (47.9%) did not have a TFS event.

Treatment discontinuation in adult CML patients in chronic phase who have achieved a sustaineddeep molecular response on nilotinib treatment following prior imatinib therapy
In an open-label, single-arm study, 163 adult patients with Ph+ CML in chronic phase taking tyrosinekinase inhibitors (TKIs) for ≥3 years (imatinib as initial TKI therapy for more than 4 weeks withoutdocumented MR4.5 on imatinib at the time of switch to nilotinib, then switched to nilotinib for at leasttwo years), and who achieved MR4.5 on nilotinib treatment as measured with the MolecularMD
MRDx BCR-ABL test were enrolled to continue nilotinib treatment for additional 52 weeks (nilotinibconsolidation phase). 126 of 163 patients (77.3%) entered the TFR phase after achieving a sustaineddeep molecular response during the consolidation phase, defined by the following criterion:
- The 4 last quarterly assessments (taken every 12 weeks) showed no confirmed loss of MR4.5(BCR-ABL/ABL ≤0.0032% IS) during one year.
The primary endpoint was the proportion of patients without confirmed loss of MR4.0 or loss of MMRwithin 48 weeks following treatment discontinuation.

5.2 Pharmacokinetic properties
AbsorptionPeak concentrations of nilotinib are reached 3 hours after oral administration. Nilotinib absorptionfollowing oral administration was approximately 30%. The absolute bioavailability of nilotinib has notbeen determined. As compared to an oral drink solution (pH of 1.2 to 1.3), relative bioavailability ofnilotinib capsule is approximately 50%. In healthy volunteers, Cmax and area under the serumconcentration-time curve (AUC) of nilotinib are increased by 112% and 82%, respectively, comparedto fasting conditions when Tasigna is given with food. Administration of Tasigna 30 minutes or2 hours after food increased bioavailability of nilotinib by 29% or 15%, respectively (see sections 4.2,4.4 and 4.5).
Nilotinib absorption (relative bioavailability) might be reduced by approximately 48% and 22% inpatients with total gastrectomy and partial gastrectomy, respectively.
DistributionThe blood-to-plasma ratio of nilotinib is 0.71. Plasma protein binding is approximately 98% on thebasis of in vitro experiments.
BiotransformationMain metabolic pathways identified in healthy subjects are oxidation and hydroxylation. Nilotinib isthe main circulating component in the serum. None of the metabolites contribute significantly to thepharmacological activity of nilotinib. Nilotinib is primarily metabolised by CYP3A4, with possibleminor contribution from CYP2C8.
EliminationAfter a single dose of radiolabelled nilotinib in healthy subjects, more than 90% of the dose waseliminated within 7 days, mainly in faeces (94% of the dose). Unchanged nilotinib accounted for 69%of the dose.
The apparent elimination half-life estimated from the multiple-dose pharmacokinetics with dailydosing was approximately 17 hours. Inter-patient variability in nilotinib pharmacokinetics wasmoderate to high.
Linearity/non-linearitySteady-state nilotinib exposure was dose-dependent, with less than dose-proportional increases insystemic exposure at dose levels higher than 400 mg given as once-daily dosing. Daily systemicexposure to nilotinib with 400 mg twice-daily dosing at steady state was 35% higher than with 800 mgonce-daily dosing. Systemic exposure (AUC) of nilotinib at steady state at a dose level of 400 mgtwice daily was approximately 13.4% higher than at a dose level of 300 mg twice daily. The averagenilotinib trough and peak concentrations over 12 months were approximately 15.7% and 14.8% higherfollowing 400 mg twice-daily dosing compared to 300 mg twice daily. There was no relevant increasein exposure to nilotinib when the dose was increased from 400 mg twice daily to 600 mg twice daily.
Steady-state conditions were essentially achieved by day 8. An increase in serum exposure to nilotinibbetween the first dose and steady state was approximately 2-fold for daily dosing and 3.8-fold fortwice-daily dosing.
Bioavailability/bioequivalence studies
Single-dose administration of 400 mg nilotinib, using 2 hard capsules of 200 mg whereby the contentof each hard capsule was dispersed in one teaspoon of apple sauce, was shown to be bioequivalentwith a single-dose administration of 2 intact hard capsules of 200 mg.
Paediatric populationFollowing administration of nilotinib in paediatric patients at 230 mg/m2 twice daily, rounded to thenearest 50 mg dose (to a maximum single dose of 400 mg), steady-state exposure and clearance ofnilotinib were found to be similar (within 2-fold) to adult patients treated with 400 mg twice daily. Thepharmacokinetic exposure of nilotinib following a single or multiple doses appeared to be comparablebetween paediatric patients from 2 years to <10 years and from ≥10 years to <18 years.
5.3 Preclinical safety data
Nilotinib has been evaluated in safety pharmacology, repeated-dose toxicity, genotoxicity,reproductive toxicity, phototoxicity and carcinogenicity (rats and mice) studies.
Safety pharmacology studies
Nilotinib did not have effects on CNS or respiratory functions. In vitro cardiac safety studiesdemonstrated a preclinical signal for QT prolongation, based upon block of hERG currents andprolongation of the action potential duration in isolated rabbit hearts by nilotinib. No effects were seenin ECG measurements in dogs or monkeys treated for up to 39 weeks or in a special telemetry study indogs.
Repeated-dose toxicity studies
Repeated-dose toxicity studies in dogs of up to 4 weeks’ duration and in cynomolgus monkeys of upto 9 months’ duration revealed the liver as the primary target organ of toxicity of nilotinib. Alterationsincluded increased alanine aminotransferase and alkaline phosphatase activity and histopathologyfindings (mainly sinusoidal cell or Kupffer cell hyperplasia/hypertrophy, bile duct hyperplasia andperiportal fibrosis). In general the changes in clinical chemistry were fully reversible after a four-weekrecovery period and the histological alterations showed partial reversibility. Exposures at the lowestdose levels at which the liver effects were seen were lower than the exposure in humans at a dose of800 mg/day. Only minor liver alterations were seen in mice or rats treated for up to 26 weeks. Mainlyreversible increases in cholesterol levels were seen in rats, dogs and monkeys.
Genotoxicity studies
Genotoxicity studies in bacterial in vitro systems and in mammalian in vitro and in vivo systems withand without metabolic activation did not reveal any evidence for a mutagenic potential of nilotinib.
Carcinogenicity studies
In the 2-year rat carcinogenicity study, the major target organ for non-neoplastic lesions was the uterus(dilatation, vascular ectasia, endothelial cell hyperplasia, inflammation and/or epithelial hyperplasia).
There was no evidence of carcinogenicity upon administration of nilotinib at 5, 15 and 40 mg/kg/day.
Exposures (in terms of AUC) at the highest dose level represented approximately 2x to 3x humandaily steady-state exposure (based on AUC) to nilotinib at the dose of 800 mg/day.
In the 26-week Tg.rasH2 mouse carcinogenicity study, in which nilotinib was administered at 30, 100and 300 mg/kg/day, skin papillomas/carcinomas were detected at 300 mg/kg, representingapproximately 30 to 40 times (based on AUC) the human exposure at the maximum approved dose of800 mg/day (administered as 400 mg twice daily). The No-Observed-Effect-Level for the skinneoplastic lesions was 100 mg/kg/day, representing approximately 10 to 20 times the human exposureat the maximum approved dose of 800 mg/day (administered as 400 mg twice daily). The major targetorgans for non-neoplastic lesions were the skin (epidermal hyperplasia), the growing teeth(degeneration/atrophy of the enamel organ of upper incisors and inflammation of thegingiva/odontogenic epithelium of incisors) and the thymus (increased incidence and/or severity ofdecreased lymphocytes).
Reproductive toxicity and fertility studies
Nilotinib did not induce teratogenicity, but did show embryo- and foetotoxicity at doses that alsoshowed maternal toxicity. Increased post-implantation loss was observed in both the fertility study,which involved treatment of both males and females, and the embryotoxicity study, which involvedtreatment of females. Embryo-lethality and foetal effects (mainly decreased foetal weights, prematurefusion of the facial bones (fused maxilla/zygomatic) visceral and skeletal variations) in rats andincreased resorption of foetuses and skeletal variations in rabbits were present in the embryotoxicitystudies. In a pre- and postnatal development study in rats, maternal exposure to nilotinib causedreduced pup body weight with associated changes in physical development parameters as well asreduced mating and fertility indices in the offspring. Exposure to nilotinib in females at
No-Observed-Adverse-Effect-Levels was generally less or equal to that in humans at 800 mg/day.
No effects on sperm count/motility or on fertility were noted in male and female rats up to the highesttested dose, approximately 5 times the recommended dosage for humans.
Juvenile animal studiesIn a juvenile development study, nilotinib was administered via oral gavage to juvenile rats from thefirst week post partum through young adult (day 70 post partum) at doses of 2, 6 and 20 mg/kg/day.
Besides standard study parameters, evaluations of developmental landmarks, CNS effects, mating andfertility were performed. Based on a reduction in body weight in both genders and a delayed preputialseparation in males (which may be associated with the reduction in weight), the
No-Observed-Effect-Level in juvenile rats was considered to be 6 mg/kg/day. The juvenile animalsdid not exert increased sensitivity to nilotinib relative to adults. In addition, the toxicity profile injuvenile rats was comparable to that observed in adult rats.
Phototoxicity studies
Nilotinib was shown to absorb light in the UV-B and UV-A range, is distributed into the skin andshowed a phototoxic potential in vitro, but no effects have been observed in vivo. Therefore the riskthat nilotinib causes photosensitisation in patients is considered very low.
