( 1.1 ) Adult patients with chronic phase (CP) and accelerated phase (AP) Ph+ CML resistant to or intolerant to prior therapy that included imatinib. ( 1.2 ) Pediatric patients greater than or equal to 1 year of age with Ph+ CML-CP resistant or intolerant to prior tyrosine-kinase inhibitor (TKI) therapy. (1.3) 1.1 Adult and Pediatric Patients With Newly Diagnosed Ph+ CML-CP Nilotinib capsules are indicated for the treatment of adult and pediatric patients greater than or equal to 1 year of age with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase. 1.2 Adult Patients With Resistant or Intolerant Ph+ CML-CP and CML-AP Nilotinib capsules are indicated for the treatment of adult patients with chronic phase and accelerated phase Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) resistant or intolerant to prior therapy that included imatinib. 1.3 Pediatric Patients With Resistant or Intolerant Ph+ CML-CP Nilotinib capsules are indicated for the treatment of pediatric patients greater than or equal to 1 year of age with chronic phase Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) with resistance or intolerance to prior tyrosine-kinase inhibitor (TKI) therapy. Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s TASIGNA (nilotinib) capsules. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

2 DOSAGE AND ADMINISTRATION Recommended Adult Dose: Newly diagnosed Ph+ CML-CP: 300 mg orally twice daily. Resistant or intolerant Ph+ CML-CP and CML-AP: 400 mg orally twice daily. ( 2.1 ) Recommended Pediatric Dose: Newly Diagnosed Ph+ CML-CP or Ph+ CML-CP resistant or intolerant to prior TKI therapy: 230 mg/m 2 orally twice daily, rounded to the nearest 50 mg dose (to a maximum single dose of 400 mg). ( 2.1 ) See Dosage and Administration for full dosing instructions and dose-reduction instructions for toxicity. ( 2.1 ) Reduce starting dose in patients with baseline hepatic impairment. ( 2.7 ) Eligible newly diagnosed adult patients with Ph+ CML-CP who have received nilotinib capsules for a minimum of 3 years and have achieved a sustained molecular response (MR4.5) and patients with Ph+ CML-CP resistant or intolerant to imatinib who have received nilotinib capsules for at least 3 years and have achieved a sustained molecular response (MR4.5) may be considered for treatment discontinuation. ( 2.2 , 2.3 , 5.16 ) 2.1 Recommended Dosage Dose nilotinib capsules twice daily at approximately 12-hour intervals on an empty stomach. No food should be consumed for at least 2 hours before the dose is taken and for at least 1 hour after the dose is taken. Advise patients to swallow the capsules whole with water [ see Boxed Warning , Clinical Pharmacology (12.3) ]. For patients who are unable to swallow capsules, the contents of each capsule may be dispersed in 1 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) ]. Nilotinib capsules may be given in combination with hematopoietic growth factors, such as erythropoietin or G-CSF if clinically indicated. Nilotinib capsules may be given with hydroxyurea or anagrelide if clinically indicated. Dosage in Adult Patients with Newly Diagnosed Ph+ CML-CP The recommended dosage of nilotinib capsules are 300 mg orally…

12.2 Pharmacodynamics Based on exposure-response analyses for efficacy, a relationship between drug exposure and a greater likelihood of response was observed in clinical studies. Based on exposure-response analyses for safety, a relationship between exposure and a greater likelihood of safety events, including a higher occurrence of total bilirubin elevations, was observed in clinical studies. Cardiac Electrophysiology Nilotinib is associated with concentration-dependent QT prolongation. At a dose of nilotinib 400 mg twice daily given without food in healthy subjects, the maximum mean placebo-adjusted QTcF changes were 10.4 msec (90% CI: 2.85, 18). After a single dose of nilotinib 800 mg (two times the maximum approved recommended dosage) given with a high fat meal to healthy subjects, the maximum mean placebo-adjusted QTcF changes were) 18 msec (90% CI: 9.65, 25.8). Peak plasma concentrations in the QT study were 26% lower than or comparable with those observed in patients enrolled in the single-arm study [ see Boxed Warning , Warnings and Precautions (5.2) , Adverse Reactions (6.1) ].

6 ADVERSE REACTIONS The following clinically significant adverse reactions can occur with nilotinib and are discussed in greater detail in other sections of labeling: 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) ] Cardiac and Arterial Vascular Occlusive Events [ see Warnings and Precautions (5.4) ] Pancreatitis and Elevated Serum Lipase [ see Warnings and Precautions (5.5) ] Hepatotoxicity [ see Warnings and Precautions (5.6) ] Electrolyte Abnormalities [ see Boxed Warning , Warnings and Precautions (5.7) ] Hemorrhage [ see Warnings and Precautions (5.9) ] Fluid Retention [ see Warnings and Precautions (5.13) ] The most commonly reported non-hematologic adverse reactions (≥ 20%) in adult and pediatric patients were 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.

7 DRUG INTERACTIONS Strong CYP3A Inhibitors : Avoid concomitant use with nilotinib, or reduce nilotinib dose if coadministration cannot be avoided. ( 7.1 ) Strong CYP3A Inducers : Avoid concomitant use with nilotinib. ( 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 Nilotinib Strong CYP3A Inhibitors Concomitant use with a strong CYP3A inhibitor increased nilotinib concentrations compared to nilotinib alone [ see Clinical Pharmacology (12.3) ] , which may increase the risk of nilotinib toxicities. Avoid concomitant use of strong CYP3A inhibitors with nilotinib. If patients must be coadministered a strong CYP3A4 inhibitor, reduce nilotinib dose [ see Dosage and Administration (2.8) ] . Strong CYP3A Inducers Concomitant use with a strong CYP3A inducer decreased nilotinib concentrations compared to nilotinib alone [ see Clinical Pharmacology (12.3) ] , which may reduce nilotinib efficacy. Avoid concomitant use of strong CYP3A inducers with nilotinib. Proton Pump Inhibitors Concomitant use with a proton pump inhibitor (PPI) decreased nilotinib concentrations compared to nilotinib alone [ see Clinical Pharmacology (12.3) ] , which may reduce nilotinib efficacy. Avoid concomitant use of PPI with nilotinib. As an alternative to PPIs, use H2 blockers approximately 10 hours before or approximately 2 hours after the dose of nilotinib, or use antacids approximately 2 hours before or approximately 2 hours after the dose of nilotinib. 7.2 Drugs That Prolong the QT Interval Avoid coadministration of nilotinib with agents that may prolong the QT interval, such as anti-arrhythmic drugs [ see Boxed Warning , Dosage and Administration (2.4) , Warnings and Precautions (5.2) , Drug Interactions (7.1) , Clinical Pharmacology (12.2) ].
