5 WARNINGS AND PRECAUTIONS • Substitution with Other Nilotinib Products and Risk of Medication Errors : DANZITEN (nilotinib) tablets may not be substitutable with other nilotinib products, including other nilotinib tablets, on a milligram per milligram basis. Confirm that the intended nilotinib product is being prescribed and dispensed. ( 5.1 ) • Myelosuppression : Monitor complete blood count (CBC) during therapy and manage by treatment interruption or dose reduction. ( 5.2 ) • Cardiac and Arterial Vascular Occlusive Events : Evaluate cardiovascular status, monitor and manage cardiovascular risk factors during DANZITEN therapy. ( 5.5 ) • Pancreatitis and Elevated Serum Lipase : Monitor serum lipase; if elevations are accompanied by abdominal symptoms, interrupt doses and consider appropriate diagnostics to exclude pancreatitis. ( 5.6 ) • Hepatotoxicity : Monitor hepatic function tests monthly or as clinically indicated. ( 5.7 ) • Electrolyte Abnormalities : DANZITEN can cause hypophosphatemia, hypokalemia, hyperkalemia, hypocalcemia, and hyponatremia. Correct electrolyte abnormalities prior to initiating DANZITEN and monitor periodically during therapy. ( 5.8 ) • Tumor Lysis Syndrome : Maintain adequate hydration and correct uric acid levels prior to initiating therapy with DANZITEN. ( 5.9 ) • Hemorrhage : Hemorrhage from any site may occur. Advise patients to report signs and symptoms of bleeding and medically manage as needed. ( 5.10 ) • Fluid Retention : Monitor patients for unexpected rapid weight gain, swelling, and shortness of breath. Manage medically. ( 5.13 ) • Effects on Growth and Development in Pediatric Patients : Growth retardation has been reported in pediatric patients treated with nilotinib. Monitor growth and development in pediatric patients. ( 5.14 ) • Embryo-Fetal Toxicity : Can cause fetal harm. Advise females of reproductive potential of potential risk to a fetus and to use effective contraception. ( 5.15 , 8.1 , 8.3 ) • Treatment Discontinuation : Patients must have typical BCR-ABL transcripts. An FDA-authorized test with a detection limit below MR4.5 must be used to determine eligibility for discontinuation. Patients must be frequently monitored by the FDA authorized test to detect possible loss of remission. ( 5.16 ) 5.1 Substitution with Other Nilotinib Products and Risk of Medication Errors Nilotinib is available in different formulations, recommended dosages, and tablet strengths, and for different indications. DANZITEN (nilotinib) tablets may not be substitutable with other nilotinib products, including other nilotinib tablets, on a milligram per milligram basis. When switching patients between other nilotinib products and DANZITEN (nilotinib) tablets, a dose conversion may be required [see Dosage and Administration ( 2.1 and 2.2 )] . Substitution of DANZITEN (nilotinib) tablets for another nilotinib product to achieve the same daily nilotinib dosage on a milligram per milligram basis may result in a clinically significant: • Increase in nilotinib exposure which may increase the risk of nilotinib-associated adverse reactions. • Decrease in nilotinib exposure which may reduce DANZITEN effectiveness. Confirm that the intended nilotinib product is being prescribed and dispensed. 5.2 Myelosuppression Treatment with DANZITEN can cause Grade 3/4 thrombocytopenia, neutropenia, and anemia. Perform CBCs every 2 weeks for the first 2 months and then monthly thereafter, or as clinically indicated. Myelosuppression was generally reversible and usually managed by withholding DANZITEN temporarily or dose reduction [ see Dosage and Administration ( 2.6 ) ]. 5.3 QT Prolongation Nilotinib has been shown to prolong cardiac ventricular repolarization as measured by the QT interval on the surface electrocardiogram (ECG) in a concentration-dependent manner [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.2 )] . Prolongation of the QT interval can result in a type of ventricular tachycardia called torsade de…

4 CONTRAINDICATIONS DANZITEN is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome [see Boxed Warning and Warnings and Precautions ( 5.3 )]. DANZITEN is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome. ( 4 )

7 DRUG INTERACTIONS • Strong CYP3A Inhibitors : Avoid concomitant use with DANZITEN or reduce DANZITEN dose if concomitant use cannot be avoided. ( 7.1 ) • Strong CYP3A Inducers : Avoid concomitant use with DANZITEN. ( 7.1 ) • Proton Pump Inhibitors : Use short-acting antacids or H2 blockers as an alternative to proton pump inhibitors. ( 7.1 ) 7.1 Effect of Other Drugs on DANZITEN Strong CYP3A Inhibitors Avoid concomitant use of strong CYP3A inhibitors with DANZITEN. If concomitant use cannot be avoided, reduce DANZITEN dose [see Dosage and Administration ( 2.9 )] . Nilotinib is a CYP3A substrate [see Clinical Pharmacology ( 12.3 )]. Concomitant use with a strong CYP3A inhibitor increases nilotinib exposure [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of DANZITEN adverse reactions. Strong CYP3A Inducers Avoid concomitant use of strong CYP3A inducers with DANZITEN. Nilotinib is a CYP3A substrate [see Clinical Pharmacology ( 12.3 )] . Concomitant use with a strong CYP3A inducer decreases nilotinib exposure [see Clinical Pharmacology ( 12.3 )] , which may reduce DANZITEN efficacy. Proton Pump Inhibitors Avoid concomitant use of PPI with DANZITEN. As an alternative to PPIs, use H 2 blockers approximately 10 hours before or approximately 2 hours after the dose of DANZITEN, or use antacids approximately 2 hours before or approximately 2 hours after the dose of DANZITEN. Nilotinib displays pH-dependent aqueous solubility [see Description ( 11 )] . Concomitant use with a proton pump inhibitor (PPI) decreases nilotinib concentrations [see Clinical Pharmacology ( 12.3 )] , which may reduce DANZITEN efficacy. 7.2 Drugs that Prolong the QT Interval Avoid coadministration of DANZITEN with agents that may prolong the QT interval, such as anti-arrhythmic drugs [see Boxed Warning, Dosage and Administration ( 2.5 ), Warnings and Precautions ( 5.3 ), Drug Interactions ( 7.1 ), Clinical Pharmacology ( 12.2 )]. Nilotinib is associated with a clinically significant concentration-dependent QT prolongation [see Clinical Pharmacology ( 12.2 )].

8.1 Pregnancy Risk Summary Based on findings from animal studies and the mechanism of action, DANZITEN can cause fetal harm when administered to a pregnant woman [ see Clinical Pharmacology ( 12.1 ) ]. There are no available data in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of nilotinib to pregnant rats and rabbits during organogenesis caused adverse developmental outcomes, including embryo-fetal lethality, fetal effects, and fetal variations in rats and rabbits at maternal exposures (AUC) approximately 2 and 0.5 times, respectively, the exposures in patients at the recommended dose (see Data). Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2%-4% and 15%-20%, respectively. Data Animal Data In embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of nilotinib up to 100 mg/kg/day and 300 mg/kg/day, respectively, during the period of organogenesis. In rats, oral administration of nilotinib produced embryo-lethality/fetal effects at doses ≥ 30 mg/kg/day. At ≥ 30 mg/kg/day, skeletal variations of incomplete ossification of the frontals and misshapen sternebra were noted, and there was an increased incidence of small renal papilla and fetal edema. At 100 mg/kg/day, nilotinib was associated with maternal toxicity (decreased gestation weight, gravid uterine weight, net weight gain, and food consumption) and resulted in a single incidence of cleft palate and two incidences of pale skin were noted in the fetuses. A single incidence of dilated ureters was noted in a fetus also displaying small renal papilla at 100 mg/kg/day. Additional variations of forepaw and hindpaw phalanx unossified, fused sternebra, bipartite sternebra ossification, and incomplete ossification of the cervical vertebra were noted at 100 mg/kg/day. In rabbits, oral administration of nilotinib resulted in the early sacrifice of two females, maternal toxicity and increased resorption of fetuses at 300 mg/kg/day. Fetal skeletal variations (incomplete ossification of the hyoid, bent hyoid, supernumerary short detached ribs and the presence of additional ossification sites near the nasals, frontals and in the sternebral column) were also increased at this dose in the presence of maternal toxicity. Slight maternal toxicity was evident at 100 mg/kg/day but there were no reproductive or embryo-fetal effects at this dose. At 30 mg/kg/day in rats and 300 mg/kg/day in rabbits, the maternal systemic exposure (AUC) were 72700 ng*hr/mL and 17100 ng*hr/mL respectively, representing approximately 2 and 0.5 times the exposure in humans at the highest recommended dose 400 mg twice daily. 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 60 mg/kg (i.e., 360 mg/m2, approximately 0.7 times the clinical dose of 400 mg twice daily based on body surface area). At doses up to 20 mg/kg (i.e., 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.

6 ADVERSE REACTIONS The following clinically significant adverse reactions can occur with DANZITEN and are discussed in greater detail in other sections of labeling: • Myelosuppression [ see Warnings and Precautions ( 5.2 ) ] • QT Prolongation [ see Boxed Warning, Warnings and Precautions ( 5.3 ) ] • Sudden Deaths [ see Boxed Warning, Warnings and Precautions ( 5.4 ) ] • Cardiac and Arterial Vascular Occlusive Events [ see Warnings and Precautions ( 5.5 ) ] • Pancreatitis and Elevated Serum Lipase [ see Warnings and Precautions ( 5.6 ) ] • Hepatotoxicity [ see Warnings and Precautions ( 5.7 ) ] • Electrolyte Abnormalities [ see Boxed Warning, Warnings and Precautions ( 5.8 ) ] • Hemorrhage [ see Warnings and Precautions ( 5.10 ) ] • Fluid Retention [ see Warnings and Precautions ( 5.13 ) ] The most commonly reported non-hematologic adverse reactions (≥ 20%) in adult patients are nausea, rash, headache, fatigue, pruritus, vomiting, diarrhea, cough, constipation, arthralgia, nasopharyngitis, pyrexia, and night sweats. Hematologic adverse drug reactions include myelosuppression: thrombocytopenia, neutropenia, and anemia.

The safety of DANZITEN (nilotinib) tablets has been established from adequate and well-controlled studies of Tasigna ® (nilotinib) capsules, which has different recommended dosages than DANZITEN, in adult patients with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase (CP) and adult patients with CP and accelerated phase (AP) Ph+ CML resistant to or intolerant to prior therapy that included imatinib [see Clinical Studies ( 14 )] . Below is a display of the adverse reactions of Tasigna ® (nilotinib) capsules in these adequate and well-controlled studies. In Adult Patients With Newly Diagnosed Ph+ CML-CP The data below reflect exposure to nilotinib from a randomized trial in patients with newly diagnosed Ph+ CML in chronic phase treated at the equivalent recommended dosage of DANZITEN 142 mg twice daily (n = 279). The median time on treatment at the equivalent recommended dosage of DANZITEN 142 mg twice daily group was 61 months (range, 0.1 to 71 months). The most common (greater than 10%) non-hematologic adverse drug reactions were rash, pruritus, headache, nausea, fatigue, alopecia, myalgia, and upper abdominal pain. Constipation, diarrhea, dry skin, muscle spasms, arthralgia, abdominal pain, peripheral edema, vomiting, and asthenia were observed less commonly (less than or equal to 10% and greater than 5%). Increase in QTcF greater than 60 msec from baseline was observed in 1 patient (0.4%) at the equivalent recommended dosage of DANZITEN 142 mg twice daily treatment group. No patient had an absolute QTcF of greater than 500 msec while on study drug. The most common hematologic adverse drug reactions (all Grades) were myelosuppression, including: thrombocytopenia (18%), neutropenia (15%), and anemia (8%). See Table 10 for Grade 3/4 laboratory abnormalities. Discontinuation due to adverse reactions, regardless of relationship to study drug, was observed in 10% of patients. In Adult Patients With Resistant or Intolerant Ph+ CML-CP and CML-AP In the single-arm, 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 equivalent recommended dosage of DANZITEN 190 mg twice daily. The median duration of exposure in days for CML-CP and CML-AP patients is 561 (range, 1 to 1…
