Nilotinib

12.1 Mechanism of Action 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. Nilotinib inhibited the autophosphorylation of the following kinases at IC50 values as indicated: BCR-ABL (20 to 60 nM), PDGFR (69 nM), c-KIT (210 nM), CSF-1R (125 to 250 nM), and DDR1 (3.7 nM).

( 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 twice daily. Dosage in Adult Patients with Resistant or Intolerant Ph+ CML-CP and CML-AP The recommended dosage of nilotinib capsules are 400 mg orally twice daily. Dosage in Pediatric Patients with Newly Diagnosed Ph+ CML-CP or Resistant or Intolerant Ph+ CML-CP The recommended dosage of nilotinib capsules for pediatric patients is 230 mg/m2 orally twice daily, rounded to the nearest 50 mg dose (to a maximum single dose of 400 mg) (see Table 1). If needed, attain the desired dose by combining different strengths of nilotinib capsules. Continue treatment as long as clinical benefit is observed or until unacceptable toxicity occurs.

Information on FDA authorized tests for the detection and quantitation of BCR-ABL transcripts to determine eligibility for treatment discontinuation is available at http://www.fda.gov/CompanionDiagnostics. Patients with typical BCR-ABL transcripts (e13a2/b2a2 or e14a2/b3a2), who achieve the sustained MR4.5 criteria, are eligible for discontinuation of nilotinib capsules. Patients must continue to be monitored for possible loss of molecular remission after treatment discontinuation. Use the same FDA-authorized test to consistently monitor molecular response levels while on and off treatment. Consider discontinuation in patients with newly diagnosed Ph+ CML-CP who have: been treated with nilotinib capsules for at least 3 years maintained a molecular response of at least MR4.0 (corresponding to = BCR-ABL/ABL ≤ 0.01% IS) for one year prior to discontinuation of therapy achieved an MR4.5 for the last assessment taken immediately prior to discontinuation of therapy been confirmed to express the typical BCR-ABL transcripts (e13a2/b2a2 or e14a2/b3a2) no history of accelerated phase or blast crisis no history of prior attempts of treatment-free remission discontinuation that resulted in relapse. Consider discontinuation i

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 recommended dose of 300 mg twice daily (n = 279). The median time on treatment in the nilotinib 300 mg twice daily group was 61 months (range, 0.1 to 71 months). The median actual dose intensity was 593 mg/day in the nilotinib 300 mg twice daily group. 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%) and have been of mild-to-moderate severity, manageable and generally did not require dose reduction. Increase in QTcF greater than 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 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 9 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 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 to 1096) and 264 (range, 2 to 1160), respectively. The median dose intensity for patients with CML-CP and CML-AP is 789 mg/day (range, 151 to 1110) and 780 mg/day (range, 150 to 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 to 345), and the median duration in days of dose interruptions for the CML-AP patients was 23 (range, 1 to 234). In patients with CML-CP, the most commonly reported non-hematologic adverse drug reactions (greater than or equal to 10%) were rash, pruritus, nausea, fatigue, headache, constipation, diarrhea, vomiting, and myalgia. The common serious drug-related adverse reactions (greater than or equal to 1% and less than 10%) were thrombocytopenia, neutropenia, and anemia. In patients with CML-AP, the most commonly reported non-hematologic adverse drug reactions (greater than or equal to 10%) were rash, pruritus and fatigue. The common serious adverse drug reactions (greater than or equal to 1% and less than 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 greater than 60 msec from baseline was observed in 4.1% of the patients and QTcF of greater than 500 msec was observed in 4 patients (less than 1%) [ see Boxed Warning , Warnings and Precautions (5.2 , 5.3) , C

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) ].
