FULL PRESCRIBING INFORMATION: CONTENTS *
Tasigna (nilotinib) is indicated for the treatment of adult patients with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase. The effectiveness of Tasigna is based on major molecular response and cytogenetic response rates [see Clinical Studies (14.1)]. The study is ongoing and further data will be required to determine long-term outcome.
Tasigna is indicated for the treatment of chronic phase and accelerated phase Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) in adult patients resistant or intolerant to prior therapy that included imatinib. The effectiveness of Tasigna is based on hematologic and cytogenetic response rates [see Clinical Studies (14.2)].
Tasigna should be taken twice daily at approximately 12 hour intervals and must not be taken with food. The capsules should be swallowed whole with water. No food should be consumed for at least 2 hours before the dose is taken and no food should be consumed for at least one hour after the dose is taken [see Boxed Warning, Warnings and Precautions (5.8), Clinical Pharmacology (12.3)].
For patients who are unable to swallow capsules, the contents of each capsule may be dispersed in one teaspoon of applesauce (puréed apple). The mixture should be taken immediately (within 15 minutes) and should not be stored for future use [see Clinical Pharmacology (12.3)].
Tasigna may be given in combination with hematopoietic growth factors such as erythropoietin or G-CSF if clinically indicated. Tasigna may be given with hydroxyurea or anagrelide if clinically indicated.
Newly Diagnosed Ph+ CML-CP
The recommended dose of Tasigna is 300 mg orally twice daily [see Clinical Pharmacology (12.3)].
Resistant or Intolerant Ph+ CML-CP and CML-AP
The recommended dose of Tasigna (nilotinib) is 400 mg orally twice daily [see Clinical Pharmacology (12.3)].
QT interval prolongation:
|ECGs with a QTc|
|1. Withhold Tasigna, and perform an analysis of serum potassium and magnesium, and if below lower limit of normal, correct with supplements to within normal limits. Concomitant medication usage must be reviewed.
2. Resume within 2 weeks at prior dose if QTcF returns to <450 msec and to within 20 msec of baseline.
3. If QTcF is between 450 msec and 480 msec after 2 weeks, reduce the dose to 400 mg once daily.
4. If, following dose-reduction to 400 mg once daily, QTcF returns to >480 msec, Tasigna should be discontinued.
5. An ECG should be repeated approximately 7 days after any dose adjustment.
Tasigna may need to be withheld and/or dose reduced for hematological toxicities (neutropenia, thrombocytopenia) that are not related to underlying leukemia (Table 2).
|Newly diagnosed Ph+ CML in chronic phase at 300 mg twice daily|
Resistant or intolerant Ph+ CML in chronic phase or accelerated phase at 400 mg twice daily
|ANC* <1.0 x 109/L and/or platelet counts <50 x 109/L||1. Stop Tasigna, and monitor blood counts
2. Resume within 2 weeks at prior dose if ANC >1.0 x 109/L and platelets >50 x 109/L
3. If blood counts remain low for >2 weeks, reduce the dose to 400 mg once daily
*ANC = absolute neutrophil count
See Table 3 for dose adjustments for elevations of lipase, amylase, bilirubin, and/or hepatic transaminases [see Adverse Reactions (6.1)].
|Elevated serum lipase or amylase ≥Grade 3||1. Withhold Tasigna, and monitor serum lipase or amylase
2. Resume treatment at 400 mg once daily if serum lipase or amylase returns to ≤Grade 1
|Elevated bilirubin ≥Grade 3||1. Withhold Tasigna, and monitor bilirubin
2. Resume treatment at 400 mg once daily if bilirubin returns to ≤Grade 1
|Elevated hepatic transaminases|
|1. Withhold Tasigna, and monitor hepatic transaminases
2. Resume treatment at 400 mg once daily if hepatic transaminases returns to ≤Grade 1
Other Non-hematologic Toxicities
If other clinically significant moderate or severe non-hematologic toxicity develops, withhold dosing, and resume at 400 mg once daily when the toxicity has resolved. If clinically appropriate, escalation of the dose back to 300 mg (newly diagnosed Ph+ CML-CP) or 400 mg (resistant or intolerant Ph+ CML-CP and CML-AP) twice daily should be considered. For Grade 3 to 4 lipase elevations, dosing should be withheld, and may be resumed at 400 mg once daily. Test serum lipase levels monthly or as clinically indicated. For Grade 3 to 4 bilirubin or hepatic transaminase elevations, dosing should be withheld, and may be resumed at 400 mg once daily. Test bilirubin and hepatic transaminases levels monthly or as clinically indicated [see Warnings and Precautions (5.4, 5.5), Use in Specific Populations (8.7)].
If possible, consider alternative therapies. If Tasigna must be administered to patients with hepatic impairment, consider the following dose reduction:
|Newly diagnosed Ph+ CML in chronic phase at 300 mg twice daily||Mild, Moderate or Severe*||An initial dosing regimen of 200 mg twice daily followed by dose escalation to 300 mg twice daily based on tolerability|
Resistant or intolerant Ph+ CML in chronic phase or accelerated phase at 400 mg twice daily
|Mild or Moderate*||An initial dosing regimen of 300 mg twice daily followed by dose escalation to 400 mg twice daily based on tolerability|
|Severe*||A starting dose of 200 mg twice daily followed by a sequential dose escalation to 300 mg twice daily and then to 400 mg twice daily based on tolerability|
* Mild = mild hepatic impairment (Child-Pugh Class A); Moderate = moderate hepatic impairment (Child-Pugh Class B); Severe = severe hepatic impairment (Child-Pugh Class C) [see Warnings and Precautions (5.9), Use in Specific Populations (8.7)].
Concomitant Strong CYP3A4 Inhibitors
Avoid the concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole). Grapefruit products may also increase serum concentrations of nilotinib and should be avoided. Should treatment with any of these agents be required, it is recommended that therapy with Tasigna be interrupted. If patients must be co-administered a strong CYP3A4 inhibitor, based on pharmacokinetic studies, consider a dose reduction to 300 mg once daily in patients with resistant or intolerant Ph+ CML or to 200 mg once daily in patients with newly diagnosed Ph+ CML-CP. However, there are no clinical data with this dose adjustment in patients receiving strong CYP3A4 inhibitors. If the strong inhibitor is discontinued, a washout period should be allowed before the Tasigna dose is adjusted upward to the indicated dose. Close monitoring for prolongation of the QT interval is indicated for patients who cannot avoid strong CYP3A4 inhibitors [see Boxed Warning, Warnings and Precautions (5.2, 5.7), Drug Interactions (7.2)].
Concomitant Strong CYP3A4 Inducers
Avoid the concomitant use of strong CYP3A4 inducers (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital). Patients should also refrain from taking St. John’s Wort. Based on the nonlinear pharmacokinetic profile of nilotinib, increasing the dose of Tasigna when co-administered with such agents is unlikely to compensate for the loss of exposure [see Drug Interactions (7.2)].
150 mg red opaque hard gelatin capsules with black axial imprint “NVR/BCR”.
200 mg light yellow opaque hard gelatin capsules with a red axial imprint “NVR/TKI”.
Do not use in patients with hypokalemia, hypomagnesemia, or long QT syndrome [see Boxed Warning].
Treatment with Tasigna can cause Grade 3/4 thrombocytopenia, neutropenia and anemia. Perform complete blood counts every two weeks for the first 2 months and then monthly thereafter, or as clinically indicated. Myelosuppression was generally reversible and usually managed by withholding Tasigna temporarily or dose reduction [see Dosage and Administration (2.2)].
Tasigna has been shown to prolong cardiac ventricular repolarization as measured by the QT interval on the surface ECG in a concentration-dependent manner [see Adverse Reactions (6.1), Clinical Pharmacology (12.4)]. Prolongation of the QT interval can result in a type of ventricular tachycardia called torsade de pointes, which may result in syncope, seizure, and/or death. ECGs should be performed at baseline, seven days after initiation, periodically as clinically indicated and following dose adjustments [see Warnings and Precautions (5.13)].
Tasigna should not be used in patients who have hypokalemia, hypomagnesemia or long QT syndrome. Hypokalemia or hypomagnesemia must be corrected prior to initiating Tasigna and these electrolytes should be monitored periodically during therapy [see Warnings and Precautions (5.13)].
Significant prolongation of the QT interval may occur when Tasigna is inappropriately taken with food and/or strong CYP3A4 inhibitors and/or medicinal products with a known potential to prolong QT. Therefore, co-administration with food must be avoided and concomitant use with strong CYP3A4 inhibitors and/or medicinal products with a known potential to prolong QT should be avoided [see Warnings and Precautions (5.7, 5.8)]. The presence of hypokalemia and hypomagnesemia may further enhance this effect [see Warnings and Precautions (5.6, 5.13)].
Sudden deaths have been reported in patients with CML treated with nilotinib in clinical studies (n= 5,661; 0.3%). The relative early occurrence of some of these deaths relative to the initiation of nilotinib suggests the possibility that ventricular repolarization abnormalities may have contributed to their occurrence.
The use of Tasigna can cause increases in serum lipase. Caution is recommended in patients with a previous history of pancreatitis. If lipase elevations are accompanied by abdominal symptoms, interrupt dosing and consider appropriate diagnostics to exclude pancreatitis. Test serum lipase levels monthly or as clinically indicated.
The use of Tasigna may result in elevations in bilirubin, AST/ALT, and alkaline phosphatase. Hepatic function tests should be checked monthly or as clinically indicated [see Warnings and Precautions (5.13)].
The use of Tasigna can cause hypophosphatemia, hypokalemia, hyperkalemia, hypocalcemia, and hyponatremia. Electrolyte abnormalities must be corrected prior to initiating Tasigna and these electrolytes should be monitored periodically during therapy [see Warnings and Precautions (5.13)].
The administration of Tasigna with agents that are strong CYP3A4 inhibitors or anti-arrhythmic drugs (including, but not limited to amiodarone, disopyramide, procainamide, quinidine and sotalol) and other drugs that may prolong QT interval (including, but not limited to chloroquine, clarithromycin, haloperidol, methadone, moxifloxacin and pimozide) should be avoided. Should treatment with any of these agents be required, it is recommended that therapy with Tasigna be interrupted. If interruption of treatment with Tasigna is not possible, patients who require treatment with a drug that prolongs QT or strongly inhibits CYP3A4 should be closely monitored for prolongation of the QT interval [see Boxed Warning, Dosage and Administration (2.2), Drug Interactions (7.2)].
The bioavailability of nilotinib is increased with food. Tasigna must not be taken with food. No food should be taken for at least 2 hours before and for at least one hour after the dose is taken. Grapefruit products and other foods that are known to inhibit CYP3A4 should be avoided [see Boxed Warning, Drug Interactions (7.2) and Clinical Pharmacology (12.3)].
Nilotinib exposure is increased in patients with impaired hepatic function. A lower starting dose is recommended for patients with mild to severe hepatic impairment (at baseline) and QT interval should be monitored closely [see Dosage and Administration (2.2) and Use in Specific Populations (8.7)].
Cases of tumor lysis syndrome have been reported in Tasigna treated patients with resistant or intolerant CML. Malignant disease progression, high WBC counts and/or dehydration were present in the majority of these cases. Due to potential for tumor lysis syndrome, maintain adequate hydration and correct uric acid levels prior to initiating therapy with Tasigna.
The exposure of nilotinib is reduced in patients with total gastrectomy. More frequent follow-up of these patients should be considered. Dose increase or alternative therapy may be considered in patients with total gastrectomy [see Clinical Pharmacology 12.3)].
Since the capsules contain lactose, Tasigna is not recommended for patients with rare hereditary problems of galactose intolerance, severe lactase deficiency with a severe degree of intolerance to lactose-containing products or of glucose-galactose malabsorption.
Complete blood counts should be performed every two weeks for the first two months and then monthly thereafter. Chemistry panels, including the lipid profile, should be checked periodically. ECGs should be obtained at baseline, seven days after initiation and periodically thereafter, as well as following dose adjustments [see Warnings and Precautions (5.2)]. Laboratory monitoring for patients receiving Tasigna may need to be performed more or less frequently at the physician’s discretion.
There are no adequate and well controlled studies of Tasigna in pregnant women. However, Tasigna may cause fetal harm when administered to a pregnant woman. Nilotinib caused embryo-fetal toxicities in animals at maternal exposures that were lower than the expected human exposure at the recommended doses of nilotinib. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of child-bearing potential should avoid becoming pregnant while taking Tasigna [see Use in Specific Populations (8.1)].
The following serious adverse reactions can occur with Tasigna and are discussed in greater detail in other sections of the package insert [see Boxed Warning, Warnings and Precautions (5)].
Myelosuppression [see Warnings and Precautions (5.1)]
QT prolongation [see Boxed Warning, Warnings and Precautions (5.2)]
Sudden deaths [see Boxed Warning, Warnings and Precautions (5.3)]
Elevated serum lipase [see Warnings and Precautions (5.4)]
Hepatotoxicity [see Warnings and Precautions (5.5)]
Electrolyte abnormalities [see Boxed Warning, Warnings and Precautions (5.6)]
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In Patients with Newly Diagnosed Ph+ CML-CP
The data below reflect exposure to Tasigna from a randomized trial in patients with newly diagnosed Ph+ CML in chronic phase treated at the recommended dose of 300 mg twice daily (n=279). The median time on treatment in the nilotinib 300 mg twice daily group was 36.4 months (range 0.1 – 46.7 months). The median actual dose intensity was 594 mg/day in the nilotinib 300 mg twice daily group.
The most common (>10%) non-hematologic adverse drug reactions were rash, pruritus, headache, nausea, fatigue and myalgia. Upper abdominal pain, alopecia, constipation, diarrhea, dry skin, muscle spasms, arthralgia, abdominal pain, peripheral edema, vomiting, pain in extremity, dyspepsia, and asthenia were observed less commonly (≤10% and >5%) and have been of mild to moderate severity, manageable and generally did not require dose reduction. Pleural and pericardial effusions, occurred in 1% and <1% of patients, respectively. Gastrointestinal hemorrhage was reported in 2.5% of patients.
Increase in QTcF >60 msec from baseline was observed in 1 patient (0.4%) in the 300 mg twice daily treatment group. No patient had an absolute QTcF of >500 msec while on study drug.
The most common hematologic adverse drug reactions (all grades) were myelosuppression including: thrombocytopenia (18%), neutropenia (15%) and anemia (7%). See Table 7 for Grade 3/4 laboratory abnormalities.
Discontinuation due to adverse reactions, regardless of relationship to study drug, was observed in 10% of patients.
In Patients with Resistant or Intolerant Ph+ CML-CP and CML-AP
In the single open-label multicenter clinical trial, a total of 458 patients with Ph+ CML-CP and CML-AP resistant to or intolerant to at least one prior therapy including imatinib were treated (CML-CP=321; CML-AP=137) at the recommended dose of 400 mg twice daily.
The median duration of exposure in days for CML-CP and CML-AP patients is 561 (range 1-1096) and 264 (range 2-1160), respectively. The median dose intensity for patients with CML-CP and CML-AP is 789 mg/day (range 151–1110) and 780 mg/day (range 150-1149), respectively and corresponded to the planned 400 mg twice daily dosing.
The median cumulative duration in days of dose interruptions for the CML-CP patients was 20 (range 1-345), and the median duration in days of dose interruptions for the CML-AP patients was 23 (range 1–234).
In patients with CML-CP, the most commonly reported non-hematologic adverse drug reactions (≥10%) were rash, pruritus, nausea, fatigue, headache, constipation, diarrhea, vomiting and myalgia. The common serious drug-related adverse reactions (≥1% and <10%) were thrombocytopenia, neutropenia and anemia.
In patients with CML-AP, the most commonly reported non-hematologic adverse drug reactions (≥10%) were rash, pruritus and fatigue. The common serious adverse drug reactions (≥1% and <10%) were thrombocytopenia, neutropenia, febrile neutropenia, pneumonia, leukopenia, intracranial hemorrhage, elevated lipase and pyrexia.
Sudden deaths and QT prolongation were reported. The maximum mean QTcF change from baseline at steady-state was 10 msec. Increase in QTcF >60 msec from baseline was observed in 4.1% of the patients and QTcF of >500 msec was observed in 4 patients (<1%) [see Boxed Warning, Warnings and Precautions (5.2, 5.3), Clinical Pharmacology (12.4)].
Discontinuation due to adverse drug reactions was observed in 16% of CML-CP and 10% of CML-AP patients.

Nilotinib is a competitive inhibitor of CYP3A4, CYP2C8, CYP2C9, CYP2D6 and UGT1A1 in vitro, potentially increasing the concentrations of drugs eliminated by these enzymes. In vitro studies also suggest that nilotinib may induce CYP2B6, CYP2C8 and CYP2C9, and decrease the concentrations of drugs which are eliminated by these enzymes.
Single-dose administration of Tasigna with midazolam (a CYP3A4 substrate) to healthy subjects increased midazolam exposure by 30%. Single-dose administration of Tasigna to healthy subjects did not change the pharmacokinetics and pharmacodynamics of warfarin (a CYP2C9 substrate). The ability of Tasigna to induce metabolism has not been determined in vivo. Exercise caution when co-administering Tasigna with substrates for these enzymes that have a narrow therapeutic index.
Nilotinib inhibits human P-glycoprotein (P-gp). If Tasigna is administered with drugs that are substrates of P-gp, increased concentrations of the substrate drug are likely, and caution should be exercised.
Nilotinib undergoes metabolism by CYP3A4, and concomitant administration of strong inhibitors or inducers of CYP3A4 can increase or decrease nilotinib concentrations significantly. The administration of Tasigna with agents that are strong CYP3A4 inhibitors should be avoided [see Boxed Warning, Dosage and Administration (2.2), Warnings and Precautions (5.2, 5.7)]. Concomitant use of Tasigna with medicinal products and herbal preparations that are potent inducers of CYP3A4 is likely to reduce exposure to nilotinib to a clinically relevant extent. Therefore, in patients receiving Tasigna, concomitant use of alternative therapeutic agents with less potential for CYP3A4 induction should be selected.
Ketoconazole: In healthy subjects receiving ketoconazole, a CYP3A4 inhibitor, at 400 mg once daily for 6 days, systemic exposure (AUC) to nilotinib was increased approximately 3-fold.
Rifampicin: In healthy subjects receiving the CYP3A4 inducer, rifampicin, at 600 mg daily for 12 days, systemic exposure (AUC) to nilotinib was decreased approximately 80%.
Nilotinib has pH-dependent solubility, with decreased solubility at higher pH. Drugs such as proton pump inhibitors that inhibit gastric acid secretion to elevate the gastric pH may decrease the solubility of nilotinib and reduce its bioavailability. In healthy subjects, co-administration of a single 400 mg dose of Tasigna with multiple doses of esomeprazole (a proton pump inhibitor) at 40 mg daily decreased the nilotinib AUC by 34%. Increasing the dose of Tasigna when co-administered with such agents is not likely to compensate for the loss of exposure. Since proton pump inhibitors affect pH of the upper GI tract for an extended period, separation of doses may not eliminate the interaction. The concomitant use of proton pump inhibitors with Tasigna should be used with caution. If an H2 blocker or an antacid is necessary, the doses between the H2 blocker and Tasigna or the doses between the antacid and Tasigna should be separated by at least several hours. However, no clinical study has been conducted to evaluate the effect of H2 blockers or antacids on nilotinib pharmacokinetics.
Nilotinib is a substrate of the efflux transporter P-glycoprotein (P-gp, ABCB1). If Tasigna is administered with drugs that inhibit P-gp, increased concentrations of nilotinib are likely, and caution should be exercised.
Pregnancy Category D [see Warnings and Precautions (5.14)].
Based on its mechanism of action and findings in animals, Tasigna may cause fetal harm when administered to a pregnant woman. There are no adequate and well controlled studies with Tasigna in pregnant women. Women should be advised to avoid becoming pregnant while on Tasigna. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.
Nilotinib was studied for effects on embryo-fetal development in pregnant rats and rabbits given oral doses of 10, 30, 100 mg/kg/day, and 30, 100, 300 mg/kg/day, respectively, during organogenesis. In rats, nilotinib at doses of 100 mg/kg/day (approximately 5.7 times the AUC in patients at the dose of 400 mg twice daily) was associated with maternal toxicity (decreased gestation weight, gravid uterine weight, net weight gain, and food consumption). Nilotinib at doses ≥30 mg/kg/day (approximately 2 times the AUC in patients at the dose of 400 mg twice daily) resulted in embryo-fetal toxicity as shown by increased resorption and post-implantation loss, and at 100 mg/kg/day, a decrease in viable fetuses. In rabbits, maternal toxicity at 300 mg/kg/day (approximately one-half the human exposure based on AUC) was associated with mortality, abortion, decreased gestation weights and decreased food consumption. Embryonic toxicity (increased resorption) and minor skeletal anomalies were observed at a dose of 300 mg/kg/day. Nilotinib is not considered teratogenic.
When pregnant rats were dosed with nilotinib during organogenesis and through lactation, the adverse effects included a longer gestational period, lower pup body weights until weaning and decreased fertility indices in the pups when they reached maturity, all at a maternal dose of 360 mg/m2 (approximately 0.7 times the clinical dose of 400 mg twice daily based on body surface area). At doses up to 120 mg/m2 (approximately 0.25 times the clinical dose of 400 mg twice daily based on body surface area) no adverse effects were seen in the maternal animals or the pups.
It is not known whether nilotinib is excreted in human milk. One study in lactating rats demonstrates that nilotinib is excreted into milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Tasigna, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
The safety and effectiveness of Tasigna in pediatric patients have not been established.
In the clinical trials of Tasigna (patients with newly diagnosed Ph+ CML-CP and resistant or intolerant Ph+ CML-CP and CML-AP), approximately 12% and 30% of patients were 65 years or over respectively.
No major differences for safety were observed in patients ≥65 years of age as compared to patients <65 years.
In the clinical trials, patients with a history of uncontrolled or significant cardiovascular disease, including recent myocardial infarction, congestive heart failure, unstable angina or clinically significant bradycardia, were excluded. Caution should be exercised in patients with relevant cardiac disorders [see Boxed Warning, Warnings and Precautions (5.2)].
Nilotinib exposure is increased in patients with impaired hepatic function. In a study of subjects with mild to severe hepatic impairment following a single dose administration of 200 mg of Tasigna, the mean AUC values were increased on average of 35%, 35% and 56% in subjects with mild (Child-Pugh class A, score 5-6), moderate (Child-Pugh class B, score 7-9) and severe hepatic impairment (Child-Pugh class C, score 10-15), respectively, compared to a control group of subjects with normal hepatic function. Table 8 summarizes the Child-Pugh Liver Function Classification applied in this study. A lower starting dose is recommended in patients with hepatic impairment and the QT interval should be monitored closely in these patients [see Dosage and Administration (2.2), Warnings and Precautions (5.9)].
|Assessment||Degree of Abnormality||Score|
|1 or 2||2|
|3 or 4||3|
|Total Bilirubin (mg/dL)||<2||1|

|Serum Albumin (g/dL)||>3.5||1|
|2.8 - 3.5||2|
|Prothrombin Time (seconds prolonged)||<4||1|
|4 - 6||2|
Clinical studies have not been performed in patients with impaired renal function. Clinical studies have excluded patients with serum creatinine concentration >1.5 times the upper limit of the normal range.
Since nilotinib and its metabolites are not renally excreted, a decrease in total body clearance is not anticipated in patients with renal impairment.
Overdose with nilotinib has been reported, where an unspecified number of Tasigna capsules were ingested in combination with alcohol and other drugs. Events included neutropenia, vomiting, and drowsiness. In the event of overdose, the patient should be observed and appropriate supportive treatment given.
Tasigna (nilotinib) belongs to a pharmacologic class of drugs known as kinase inhibitors.
Nilotinib drug substance, a monohydrate monohydrochloride, is a white to slightly yellowish to slightly greenish yellow powder with the anhydrous molecular formula and weight, respectively, of C28H22F3N7O•HCl • H2O and 584. The solubility of nilotinib in aqueous solutions decreases with increasing pH. Nilotinib is not optically active. The pKa1 was determined to be 2.1; pKa2 was estimated to be 5.4.
The chemical name of nilotinib is 4-methyl-N-[3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)phenyl]-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-benzamide, monohydrochloride, monohydrate. Its structure is shown below:
Tasigna (nilotinib) capsules, for oral use, contain 150 mg or 200 mg nilotinib base, anhydrous (as hydrochloride, monohydrate) with the following inactive ingredients: colloidal silicon dioxide, crospovidone, lactose monohydrate, magnesium stearate and polyoxamer 188. The capsules contain gelatin, iron oxide (red), iron oxide (yellow), iron oxide (black) and titanium dioxide.
Nilotinib is an inhibitor of the BCR-ABL kinase. Nilotinib binds to and stabilizes the inactive conformation of the kinase domain of ABL protein. In vitro, nilotinib inhibited BCR-ABL mediated proliferation of murine leukemic cell lines and human cell lines derived from patients with Ph+ CML. Under the conditions of the assays, nilotinib was able to overcome imatinib resistance resulting from BCR-ABL kinase mutations, in 32 out of 33 mutations tested. In vivo, nilotinib reduced the tumor size in a murine BCR-ABL xenograft model. Nilotinib inhibited the autophosphorylation of the following kinases at IC50 values as indicated: BCR-ABL (20-60 nM), PDGFR (69 nM), c-KIT (210 nM), CSF-1R (125-250 nM) and DDR1 (3.7 nM).
Absorption and Distribution
The absolute bioavailability of nilotinib has not been determined. As compared to an oral drink solution (pH of 1.2 to 1.3), relative bioavailability of nilotinib capsule is approximately 50%. Peak concentrations of nilotinib are reached 3 hours after oral administration.
Steady-state nilotinib exposure was dose-dependent with less than dose-proportional increases in systemic exposure at dose levels higher than 400 mg given as once daily dosing. Daily serum exposure to nilotinib following 400 mg twice daily dosing at steady state was 35% higher than with 800 mg once daily dosing. Steady state exposure (AUC) of nilotinib with 400 mg twice daily dosing was 13% higher than with 300 mg twice daily dosing. The average steady state nilotinib trough and peak concentrations did not change over 12 months. There was no relevant increase in exposure to nilotinib when the dose was increased from 400 mg twice daily to 600 mg twice daily.
The bioavailability of nilotinib was increased when given with a meal. Compared to the fasted state, the systemic exposure (AUC) increased by 82% when the dose was given 30 minutes after a high fat meal.
Single dose administration of two 200 mg nilotinib capsules each dispersed in one teaspoon of applesauce and administered within 15 minutes was shown to be bioequivalent to a single dose administration of two 200 mg intact capsules. The blood-to-serum ratio of nilotinib is 0.68. Serum protein binding is approximately 98% on the basis of in vitro experiments.
Median steady-state trough concentration of nilotinib was decreased by 53% in patients with total gastrectomy compared to patients who had not undergone surgeries [see Warnings and Precautions (5.11)].
Pharmacokinetics, Metabolism and Excretion
The apparent elimination half-life estimated from the multiple dose pharmacokinetic studies with daily dosing was approximately 17 hours. Inter-patient variability in nilotinib AUC was 32% to 64%. Steady state conditions were achieved by Day 8. An increase in serum exposure to nilotinib between the first dose and steady state was approximately 2-fold for daily dosing and 3.8-fold for twice-daily dosing.
Main metabolic pathways identified in healthy subjects are oxidation and hydroxylation. Nilotinib is the main circulating component in the serum. None of the metabolites contribute significantly to the pharmacological activity of nilotinib.
After a single dose of radiolabeled nilotinib in healthy subjects, more than 90% of the administered dose was eliminated within 7 days: mainly in feces (93% of the dose). Parent drug accounted for 69% of the dose.
Age, body weight, gender, or ethnic origin did not significantly affect the pharmacokinetics of nilotinib.
In a Phase 1 trial of nilotinib 400 mg twice daily in combination with imatinib 400 mg daily or 400 mg twice daily, the AUC increased 30%-50% for nilotinib and approximately 20% for imatinib.
In a placebo-controlled study in healthy volunteers designed to assess the effects of Tasigna on the QT interval, administration of Tasigna was associated with concentration-dependent QT prolongation; the maximum mean placebo-adjusted QTcF change from baseline was 18 msec (1-sided 95% Upper CI: 26 msec). A positive control was not included in the QT study of healthy volunteers. Peak plasma concentrations in the QT study were 26% lower than those observed in patients enrolled in the single-arm study [see Boxed Warning, Warnings and Precautions (5.2) and Adverse Reactions (6.1)].
Tasigna can increase bilirubin levels. A pharmacogenetic analysis of 97 patients evaluated the polymorphisms of UGT1A1 and its potential association with hyperbilirubinemia during Tasigna treatment. In this study, the (TA)7/(TA)7 genotype was associated with a statistically significant increase in the risk of hyperbilirubinemia relative to the (TA)6/(TA)6 and (TA)6/(TA)7 genotypes. However, the largest increases in bilirubin were observed in the (TA)7/(TA)7 genotype (UGT1A1*28) patients [see Warnings and Precautions (5.5)].
A 2-year carcinogenicity study was conducted orally in rats at nilotinib doses of 5, 15 and 40 mg/kg/day. Exposures in animals at the highest dose tested were approximately 2-3 fold the human exposure (based on AUC) at the nilotinib dose of 400 mg twice daily. The study was negative for carcinogenic findings.
Nilotinib was not mutagenic in a bacterial mutagenesis (Ames) assay, was not clastogenic in a chromosome aberration assay in human lymphocytes, did not induce DNA damage (comet assay) in L5178Y mouse lymphoma cells, nor was it clastogenic in an in vivo rat bone marrow micronucleus assay with two oral treatments at doses up to 2000 mg/kg/dose.
There were no effects on male or female rat and female rabbit mating or fertility at doses up to 180 mg/kg in rats (approximately 4-7 fold for males and females, respectively, the AUC in patients at the dose of 400 mg twice daily) or 300 mg/kg in rabbits (approximately one-half the AUC in patients at the dose of 400 mg twice daily). The effect of Tasigna on human fertility is unknown. In a study where male and female rats were treated with nilotinib at oral doses of 20-180 mg/kg/day (approximately 1-6.6 fold the AUC in patients at the dose of 400 mg twice daily) during the pre-mating and mating periods and then mated, and dosing of pregnant rats continued through gestation Day 6, nilotinib increased post-implantation loss and early resorption, and decreased the number of viable fetuses and litter size at all doses tested.
An open label, multicenter, randomized trial was conducted to determine the efficacy of Tasigna versus imatinib tablets in adult patients with cytogenetically confirmed newly diagnosed Ph+ CML-CP. Patients were within six months of diagnosis and were previously untreated for CML-CP, except for hydroxyurea and/or anagrelide. Efficacy was based on a total of 846 patients: 283 patients in the imatinib 400 mg once daily group, 282 patients in the nilotinib 300 mg twice daily group, 281 patients in the nilotinib 400 mg twice daily group.
Median age was 46 years in the imatinib group and 47 years in both nilotinib groups, with 12%, 13% and 10% of patients ≥65 years of age in imatinib 400 mg once daily, nilotinib 300 mg twice daily and nilotinib 400 mg twice daily treatment groups, respectively. There were slightly more male than female patients in all groups (56%, 56% and 62% in imatinib 400 mg once daily, nilotinib 300 mg twice daily and nilotinib 400 mg twice daily treatment groups, respectively). More than 60% of all patients were Caucasian, and 25% were Asian.
The primary data analysis was performed when all 846 patients completed 12 months of treatment (or discontinued earlier). Subsequent analyses were done when patients completed 24 and 36 months of treatment (or discontinued earlier). The median time on treatment was approximately 36 months in all three treatment groups. This study is on-going and further data will be required to determine long-term outcome.
The primary efficacy endpoint was major molecular response (MMR) at 12 months after the start of study medication. MMR was defined as ≤0.1% BCR-ABL/ABL % by international scale measured by RQ-PCR, which corresponds to a ≥3 log reduction of BCR-ABL transcript from standardized baseline. Efficacy endpoints are summarized in Table 9 below.
Two patients in the nilotinib arm progressed to either accelerated phase or blast crisis (both within the first 6 months of treatment) while 17 patients on the imatinib arm progressed to either accelerated phase or blast crisis (8 patients within first 6 months, 4 within 6-12 months, 4 within 12-18 months and 1 within 18-24 months). Between the 24 and 36 month analyses, there were no new progressions to AP/BC in either treatment arm.
|N = 282||N = 283|
|MMR at 12 months (95% CI)||44% (38.4, 50.3)||22% (17.6, 27.6)|
|CCyRb by 12 months (95% CI)||80% (75.0, 84.6)||65% (59.2, 70.6)|
|MMR at 24 months (95% CI)||62% (55.8,67.4)||38% (31.8,43.4)|
|CCyRb by 24 months (95% CI)||87% (82.4,90.6)||77% (71.7, 81.8)|

b CCyR: 0% Ph+ metaphases. Cytogenetic responses were based on the percentage of Ph-positive metaphases among ≥20 metaphase cells in each bone marrow sample.
A single arm, open label, multicenter study was conducted to evaluate the efficacy and safety of Tasigna (400 mg twice daily) in patients with imatinib-resistant or -intolerant CML with separate cohorts for chronic and accelerated phase disease. The definition of imatinib resistance included failure to achieve a complete hematologic response (by 3 months), cytogenetic response (by 6 months) or major cytogenetic response (by 12 months) or progression of disease after a previous cytogenetic or hematologic response. Imatinib intolerance was defined as discontinuation of treatment due to toxicity and lack of a major cytogenetic response at time of study entry. At the time of data cut-off, 321 patients with CML-CP and 137 patients with CML-AP with a minimum follow-up of 24 months were enrolled. In this study, about 50% of CML-CP and CML-AP patients were males, over 90% (CML-CP) and 80% (CML-AP) were Caucasian, and approximately 30% were age 65 years or older.
Overall, 73% of patients were imatinib resistant while 27% were imatinib intolerant. The median time of prior imatinib treatment was approximately 32 (CML-CP) and 28 (CML-AP) months. Prior therapy included hydroxyurea in 85% of patients, interferon in 56% and stem cell or bone marrow transplant in 8%. The median highest prior imatinib dose was 600 mg/day for patients with CML-CP and CML-AP, and the highest prior imatinib dose was ≥600 mg/day in 74% of all patients with 40% of patients receiving imatinib doses ≥800 mg/day.
Median duration of nilotinib treatment was 18.4 months in patients with CML-CP and 8.7 months in patients with CML-AP.
The efficacy endpoint in CML-CP was unconfirmed major cytogenetic response (MCyR) which included complete and partial cytogenetic responses.
The efficacy endpoint in CML-AP was confirmed hematologic response (HR), defined as either a complete hematologic response (CHR) or no evidence of leukemia (NEL). The rates of response for CML-CP and CML-AP patients are reported in Table 10.
Median durations of response had not been reached at the time of data analysis.
|Cytogenetic Response Rate (Unconfirmed) (%)a|
(n = 321)
|Major (95% CI)||51% (46% - 57%)|
|Complete (95% CI)||37% (32% - 42%)|
|Partial (95% CI)||15% (11% – 19%)|
(n = 137)
|Hematologic Response Rate (Confirmed) (95% CI)b||39% (31% - 48%)|
|Complete Hematologic Response Rate (95% CI)||30% (22% - 38%)|
|No Evidence of Leukemia (95% CI)||9% (5% -16%)|
a Cytogenetic response criteria: Complete (0% Ph + metaphases) or partial (1%-35%). Cytogenetic responses were based on the percentage of Ph-positive metaphases among ≥20 metaphase cells in each bone marrow sample.
b Hematologic response = CHR + NEL (all responses confirmed after 4 weeks).
CHR (CML-CP): WBC <10 x 109/L, platelets <450,000/mm3, no blasts or promyelocytes in peripheral blood, <5% myelocytes + metamyelocytes in bone marrow, <20% basophils in peripheral blood, and no extramedullary involvement.
CHR (CML-AP): neutrophils >1.5 x 109/L, platelets >100 x 109 /L, no myeloblasts in peripheral blood, myeloblasts <5% in bone marrow, and no extramedullary involvement.
NEL: same criteria as for CHR but neutrophils >1.0 x 109/L and platelets >20 x 109/L without transfusions or bleeding.
Patients with Chronic Phase
The MCyR rate in 321 CML-CP patients was 51%. The median time to MCyR among responders was 2.8 months (range 1 to 28 months). The median duration of MCyR cannot be estimated. The median duration of exposure on this single arm trial was 18.4 months. Among the CML-CP patients who achieved MCyR, 62% of them had MCyR lasting more than 18 months. The CCyR rate was 37%.
Patients with Accelerated Phase
The overall confirmed hematologic response rate in 137 patients with CML-AP was 39%. The median time to first hematologic response among responders was 1.0 month (range 1 to 14 months). Among the CML-AP patients who achieved HR, 44% of them had a response lasting for more than 18 months.
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.
