Nilotinib prolongs the QT interval. Prior to nilotinib administration and periodically, monitor for hypokalemia or hypomagnesemia and correct deficiencies. Obtain ECGs to monitor the QTc at baseline, 7 days after initiation, and periodically thereafter, and following any dose adjustments. Sudden deaths have been reported in patients receiving nilotinib. Do not administer nilotinib to patients with hypokalemia, hypomagnesemia, or long QT syndrome. Avoid use of concomitant drugs known to prolong the QT interval and strong CYP3A4 inhibitors. Avoid food 2 hours before and 1 hour after taking a nilotinib dose.
Note: Round dose to the nearest 50 mg increment; may combine different capsule strengths to achieve desired dose. Correct hypokalemia and/or hypomagnesemia prior to nilotinib initiation. Do not administer nilotinib to patients with long QT syndrome. Maintain adequate hydration and treat high uric acid levels prior to nilotinib initiation.

Adverse event |
Severity |
Dosage modification |
---|---|---|
Hematologic toxicity (unrelated to underlying leukemia): |
ANC <1,000/mm3 and/or platelets <50,000/mm3 |
Withhold nilotinib and monitor blood counts. If ANC >1,500/mm3 and platelets >75,000/mm3 within 2 weeks: Resume nilotinib at prior dose. If blood counts remain low for >2 weeks: Reduce nilotinib dose to 230 mg/m2 once daily or if previous dose was 230 mg/m2 once daily, consider discontinuation of treatment. |
Nonhematologic toxicities | ||
QT prolongation |
ECG with QTc prolongation >480 msec |
Withhold nilotinib and monitor and correct potassium and magnesium levels; review concurrent medications. If QTcF returns to <450 msec and to within 20 msec of baseline within 2 weeks: Resume nilotinib at prior dose. If QTcF returns to 450 to 480 msec after 2 weeks: Reduce nilotinib dose to 230 mg/m2 once daily. If QTcF returns to >480 msec after dosage reduction to 230 mg/m2 once daily: Discontinue nilotinib. Repeat ECG ~7 days after any nilotinib dosage adjustment. |
Amylase or lipase elevations |
≥ Grade 3 |
Withhold nilotinib, monitor serum amylase and lipase until levels return to ≤ grade 1. If prior dose 230 mg/m2 once daily: Discontinue nilotinib. If prior dose 230 mg/m2 twice daily: Once ≤ grade 1, resume nilotinib at 230 mg/m2 once daily. |
Lipase increases in conjunction with abdominal symptoms |
Any |
Withhold nilotinib; consider diagnostics to exclude pancreatitis. |
Other clinically significant moderate or severe nonhematologic toxicity (including medically severe fluid retention) |
Withhold nilotinib until toxicity resolves. If prior dose is 230 mg/m2 once daily: Discontinue nilotinib. If prior dose 230 mg/m2 twice daily: Resume nilotinib at 230 mg/m2 once daily. May escalate back to 230 mg/m2 twice daily if clinically appropriate. |
There are no dosage adjustments provided in the manufacturer's labeling (has not been studied); however, nilotinib and its metabolites have minimal renal excretion; dosage adjustments for renal dysfunction may not be necessary.
Children and Adolescents: Oral:
Baseline: A reduced dosage and close monitoring of ECG (for QT prolongation) is recommended; based on experience in adult patients, it is recommended to consider alternative therapies if possible.
Hepatotoxicity occurring during treatment:
If elevated ALT or AST ≥ grade 3: Withhold treatment and monitor transaminases; when ALT or AST elevation returns to ≤ grade 1, resume treatment at 230 mg/m2 once daily (if previous dose was 230 mg/m2 twice daily).
If previous dose was already 230 mg/m2 once daily and recovery to ≤ grade 1 was longer than 28 days, discontinue treatment.
If elevated bilirubin ≥ grade 2: Withhold treatment and monitor bilirubin; when bilirubin elevation returns to ≤ grade 1, resume treatment at 230 mg/m2/dose once daily (if previous dose was 230 mg/m2 twice daily).
If previous dose was already 230 mg/m2 once daily and recovery to ≤ grade 1 was longer than 28 days, discontinue treatment.
(For additional information see "Nilotinib: Drug information")
Note: Correct hypokalemia and/or hypomagnesemia prior to nilotinib initiation. Do not administer nilotinib to patients with long QT syndrome.

Concerns related to adverse effects:
• Bone marrow suppression: Nilotinib may cause myelosuppression, including grades 3 and 4 thrombocytopenia, neutropenia, and anemia; myelosuppression is generally reversible.
• Cardiovascular: Cardiovascular events such as ischemic heart disease-related events, arterial vascular occlusive events, peripheral arterial occlusive disease, and ischemic cerebrovascular accident have been reported. Assess patients for cardiovascular risk factors.
• Electrolyte imbalance: Electrolyte abnormalities may occur during treatment, including hypophosphatemia, hyper-/hypokalemia, hypocalcemia, and hyponatremia.
• Fluid retention: Fluid retention, including pleural and pericardial effusions, ascites, and pulmonary edema, were reported; may be severe. Signs/symptoms of fluid retention include rapid weight gain or swelling; symptoms of respiratory or cardiac distress include shortness of breath.
• Hemorrhage: Serious hemorrhagic events (including fatal events) have occurred in chronic myelogenous leukemia (CML) patients treated with nilotinib. In a clinical study comparing nilotinib and imatinib in the treatment of newly diagnosed Philadelphia chromosome-positive (Ph+) chronic phase CML, hemorrhagic events (eg, GI hemorrhage, including grade 3 or 4 events) occurred more frequently in the nilotinib arm.
• Hepatotoxicity: Nilotinib may cause hepatotoxicity, including elevations in bilirubin, transaminases, and alkaline phosphatase; grade 3 or 4 bilirubin, AST, and ALT elevations were observed more frequently in pediatric versus adult patients.
• Pancreatitis: Nilotinib may cause increases in serum lipase. Patients with a history of pancreatitis may be at increased risk for lipase increases.
• QT prolongation/sudden death: Nilotinib prolongs the QT interval; sudden deaths have been reported. Avoid use of concomitant drugs known to prolong the QT interval and strong CYP3A4 inhibitors; also avoid concurrent use with antiarrhythmics; may increase the risk of potentially fatal arrhythmias. The sudden deaths reported appear to be related to dose-dependent ventricular repolarization abnormalities. Prolonged QT interval may result in torsade de pointes, which may cause syncope, seizure, and/or death. Patients with uncontrolled or significant cardiovascular disease were excluded from studies.
• Tumor lysis syndrome: Tumor lysis syndrome (TLS) has been reported in patients with resistant or intolerant CML; the majority of cases had malignant disease progression, high WBC counts, and/or dehydration.
Disease-related concerns:
• Gastrectomy: Consider alternative therapy or a dosage increase (with more frequent monitoring) in patients with total gastrectomy (nilotinib exposure is reduced).
Special populations:
• Pediatrics: Growth retardation has been reported in pediatric patients with Ph+ CML in chronic phase. Monitor bone growth/development in pediatric patients.
• Polymorphisms: UGT1A1 polymorphisms may be a risk factor for increased toxicity (eg, hyperbilirubinemia) (Shibata 2014).
Dosage form specific issues:
• Lactose: Capsules contain lactose; do not use with galactose intolerance, severe lactase deficiency, or glucose-galactose malabsorption syndromes.
Other warnings/precautions:
• Appropriate administration: Food increased the bioavailability/serum levels, which may then prolong QTc. Nilotinib solubility is decreased at higher pH; concurrent use with proton pump inhibitors is not recommended.
• BCR-ABL transcript monitoring: Monitor BCR-ABL transcript levels in patients eligible for treatment discontinuation using an authorized test validated to measure molecular response levels with a sensitivity of at least MR4.5 (BCR-ABL/ABL ≤0.0032% IS). Information on authorized tests for detection and quantitation of BCR-ABL transcripts is available at http://www.fda.gov/CompanionDiagnostics.
With tyrosine-kinase inhibitor therapy, hyper- and hypothyroidism has been reported; pediatric-specific reports are lacking; however, thyroid function should be monitored in pediatric patients regularly during therapy since it is essential for normal growth and development (Hamnvik 2011; Kim 2010; Samis 2016)

Changes in menstrual patterns have been reported with tyrosine kinase inhibitor (TKI) therapy (Yu 2019).
Based on the mechanism of action, TKIs have the potential to adversely affect fertility by acting on receptors in the ovaries or testes; primarily when administered prior to puberty in males. Although there are cases showing difficulty conceiving, successful pregnancies have also been reported. Fertility data related to long-term TKI use are limited. Recommendations are available for fertility preservation prior to TKI treatment (ASCO [Oktay 2018]; Madabhavi 2019; Rambhatla 2021).
Patients planning to become pregnant but currently receiving a TKI should minimize the risk of first trimester exposure (Rambhatla 2021). Discontinuing TKI for chronic myelogenous leukemia can be considered if the patient is eligible for a tumor-free remission, allowing a washout period before attempting to conceive (Baccarani 2019; ELN [Hochhaus 2020]; Madabhavi 2019). Because the time to conception can be highly variable, treatment may also be discontinued at the first positive pregnancy test, prior to organogenesis in select patients (Abruzzese 2020).
Outcome data following male use of nilotinib prior to conception are available (Assi 2021; Carlier 2017; Szakács 2020). Based on available data, nilotinib does not need to be stopped prior to conception in patients planning to father a child (Abruzzese 2020; Baccarani 2019; ELN [Hochhaus 2020]).
Nilotinib crosses the placenta (Chelysheva 2018b).
Limited outcome data following use of nilotinib for the treatment of chronic myeloid leukemia (CML) during pregnancy are available (Assi 2021; Barkoulas 2018; Dou 2019; Lasica 2019; Madabhavi 2019). Based on data from animal reproduction studies and the mechanism of action, nilotinib may cause fetal harm if administered during pregnancy.
Treatment of CML in pregnant patients should be individualized based on gestational age, hematologic parameters, and clinical condition at presentation. If pregnancy is detected in the first trimester in patients already receiving a tyrosine kinase inhibitor (TKI), treatment should be discontinued as soon as pregnancy is confirmed. Treatments other than a TKI are recommended in pregnant patients not eligible for a tumor-free remission. If a TKI is needed, nilotinib may be considered after the first trimester; however, second generation TKIs such as nilotinib have less pregnancy outcome information and should be avoided until after delivery when possible. Close maternal and fetal monitoring is recommended (Abruzzese 2020; BSH [Smith 2020]; ELN [Hochhaus 2020]; Madabhavi 2019).
The European Society for Medical Oncology has published guidelines for diagnosis, treatment, and follow-up of cancer during pregnancy. The guidelines recommend referral to a facility with expertise in cancer during pregnancy and encourage a multidisciplinary team (obstetrician, neonatologist, oncology team) approach (ESMO [Peccatori 2013]).
A long-term observational research study is collecting information about the diagnosis and treatment of cancer during pregnancy. For additional information about the pregnancy and cancer registry or to become a participant, contact Cooper Health (1-877-635-4499).

Pediatric patients: Thyroid-stimulating hormone (TSH) and free T4 levels 4 to 6 weeks after initiation of therapy, then every 6 to 12 months or if symptoms of hyper/hypothyroid develop (Samis 2016)
Adult patients: Baseline TSH in all patients, if not on thyroid hormone replacement, recheck TSH monthly for 4 months, then every 2 to 3 months. If on preexisting thyroid replacement therapy, recheck every 4 weeks until TSH concentrations and levothyroxine doses are stable, then every 2 months thereafter (Hamnvik 2011).
In adult patients who discontinue nilotinib after a sustained molecular response (MR4.5), monitor BCR-ABL transcript levels and CBC with differential monthly for 1 year, then every 6 weeks for the second year, and every 12 weeks thereafter. Upon the loss of MR4.0 (corresponding to BCR-ABL/ABL ≤0.01% IS) during the treatment-free phase, monitor BCR-ABL transcript levels every 2 weeks until the BCR-ABL levels remain lower than major molecular response (MMR, corresponding to MR3.0 or BCR-ABL/ABL ≤0.1% IS) for 4 consecutive measurements; patients can then proceed to the original monitoring schedule. In patients who have reinitiated nilotinib after loss of molecular response, monitor CBC and BCR-ABL transcript levels every 4 weeks until a major molecular response (MR4.0) is reestablished, and then every 12 weeks thereafter.
Nilotinib is a selective tyrosine kinase inhibitor that targets BCR-ABL kinase, c-KIT and platelet derived growth factor receptor (PDGFR); it does not have activity against the SRC family. Nilotinib inhibits BCR-ABL mediated proliferation of leukemic cell lines by binding to the ATP-binding site of BCR-ABL and inhibiting tyrosine kinase activity. Nilotinib has activity in imatinib-resistant BCR-ABL kinase mutations.
Protein binding: ~98%
Metabolism: Hepatic; oxidation and hydroxylation, via CYP3A4 to primarily inactive metabolites
Bioavailability: Capsule: ~50% (when compared to oral solution with pH of 1.2 to 1.3); two 200 mg capsules sprinkled on applesauce was determined to be bioequivalent to two 200 mg intact capsules. Bioavailability is increased 82% when administered 30 minutes after a high-fat meal
Half-life elimination: ~17 hours
Time to peak: 3 hours
Excretion: Feces (93%; 69% as parent drug)
Hepatic function impairment: Following a single 200 mg dose, the mean AUC increased 1.4-fold in patients with Child-Pugh classes A and B impairment and 1.6-fold in patients with Child Pugh class C impairment compared to subjects with normal hepatic function.
Total gastrectomy: Median steady-state trough concentrations are decreased by 53% (compared to patients who had not undergone gastric surgeries).
