Pharmacologic class: Protein-tyrosine kinase inhibitor
Therapeutic class: Antineoplastic
Pregnancy risk category D
FDA Box Warning
Drug prolongs QT interval and may lead to sudden death. Don't give to patients with hypokalemia, hypomagnesemia, or long-QT syndrome. Correct hypokalemia or hypomagnesemia before starting drug and monitor for these imbalances periodically. Avoid concomitant drugs known to prolong QT interval; also avoid strong CYP3A4 inhibitors. Instruct patient not to eat 2 hours before or 1 hour after taking dose. Obtain ECG to monitor QTc at baseline, 7 days after drug initiation, periodically thereafter, and after dosage adjustments.
Reduce dosage in patients with hepatic impairment.

Drug-Drug interactionStrong CYP3A4 inhibitors including ketoconazole, itraconaole, voriconazole, clarithromycin, telithromycin, atazanavir, indinavir, nelfinavir, ritonavir, saquinavir, and nefazodone may result in ↑ blood levels and toxicity and should be avoided if possible; if concurrent use is necessary, ↓ nilotinib dose.Strong CYP3A4 inducers including carbamazepine, dexamethasone, phenobarbital, phenytoin, rifabutin, rifampin, and rifapentin may ↓ blood levels and effectiveness and should be avoided.Nilotinib inhibits the following enzyme systems: CYP3A4, CYP2C8, CYP2C9, and CYP2D6 ; concurrent use of drugs metabolized by these systems may result in toxicity of these agents.Nilotinib induces the following enzyme systems: CYP2D6, CYP2C8, CYP2C9 ; concurrent use of drugs metabolized by these systems may result ↓ therapeutic effectiveness of these agents.Concurrent use of other drugs that prolong QT interval ; may ↑ risk of serious arrhythmias; avoid concomitant use.Proton pump inhibitors, H2 receptor antagonists, and antacids may ↓ the bioavailability of nilotinib; avoid concurrent use of proton pump inhibitors; doses of H2 receptor antagonists may be administered 10 hr before or 2 hr after nilotinib; doses of antacids may be administered 2 hr before or after nilotinib.May ↑ midazolam levels.St. John's wort may ↓ levels and effectiveness; avoid concurrent use.Grapefruit juice may ↑ blood levels and toxicity and should be avoided.
Newly Diagnosed Ph+ CML Chronic Phase

Resistant or Intolerant Ph+ CML Chronic or Accelerated Phase
Hepatic ImpairmentOral (Adults) Mild or moderate hepatic impairment—300 mg twice daily; may ↑ to 400 mg twice daily if tolerates; Severe hepatic impairment—200 mg twice daily; may ↑ to 300 mg twice daily, and eventually to 400 mg twice daily if tolerates
- Monitor ECG to assess the QTc interval at baseline, 7 days after initiation of therapy, and periodically thereafter. For ECGs with QTc >480 msec, withhold nilotinib and check serum potassium and magnesium. If below lower limit of normal, correct to normal with supplements. Review concomitant medications for effects on electrolytes. If QTc returns to <450 msec and within 20 msec of baseline within 2 wk, return ot prior dose. If QTc is <480 msec and >450 msec after 2 wk, reduce nilotinib dose to 400 mg once daily. Following dose reduction to 400 mg once daily, if QTc return to >480 msec, discontinue nilotinib. Repeat ECG approximately 7 days after any dose adjustment.
- Monitor for myelosuppression. Assess for bleeding (bleeding gums, bruising, petechiae, blood in stools, urine, emesis) and avoid IM injections and taking rectal temperatures if platelet count is low. Apply pressure to venipuncture sites for at least 10 min. Assess for signs of infection during neutropenia. Anemia may occur. Monitor for fatigue, dyspnea, and othrostatic hypotension.
- Monitor for tumor lysis syndrome (malignant disease progression, high WBC counts, hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcamia, and/or dehydration). Prevent by maintain adequate hydration and correcting uric acid levels prior to starting nilotinib.
- Lab Test Considerations: Monitor serum electrolytes prior to and periodically during therapy. May cause hypokalemia, hypomagnesemia, hypophosphatemia, hyperkalemia, hypocalcemia, hyperglycemia, and hyponatremia.
- Monitor CBC every 2 wk for first 2 mo and monthly thereafter or as indicated. May cause Grade 3/4 thrombocytopenia, neutropenia, and anemia. If ANC is <1.0 × 109/L and/or platelet counts <50 × 109/L, stop nilotinib and monitor blood counts. Resume within 2 wk at prior dose if ANC >1.0 × 109/L and platelets >50 × 109/L. If blood counts remain low for >2 wk, reduce dose to 400 mg once daily. Myelosuppression is generally reversible.
- May cause ↑ serum lipase or amylase. If ↑ to ≥Grade 3, withhold nilotinib and monitor serum levels. Resume treatment at 400 mg once daily if serum lipase or amylase return to ≤Grade 1.
- May cause ↑ serum bilirubin. If ↑ to ≥Grade 3, withhold nilotinib and monitor bilirubin. Resume treatment at 400 mg once daily if serum lipase or amylase return to ≤Grade 1.
- May cause ↑ serum hepatic tranaminases. If ↑ to ≥Grade 3, withhold nilotinib and monitor serum ALT, AST, and alkaline phosphatase. Resume treatment at 400 mg once daily if serum lipase or amylase return to ≤Grade 1.

Caution patient to avoid crowds and persons with known infections. Instruct patients to use a soft toothbrush and electric razor and to avoid falls. Caution patient not to drink alcoholic beverages or take medication containing aspirin or NSAIDs; may precipitate bleeding.
- Instruct patient not to receive any vaccinations without advice of health care professional.
- Discuss the possibility of hair loss with patient. Explore methods of coping. Regrowth usually occurs 2–3 mo after discontinuation of therapy.
