Pharmacology

Potent inhibitor of anaplastic lymphoma kinase (ALK), a tyrosine kinase involved in the pathogenesis of non-small cell lung cancer. ALK gene abnormalities due to mutations or translocations may result in expression of oncogenic fusion proteins (eg, ALK fusion protein) which alter signaling and expression and result in increased cellular proliferation and survival in tumors which express these fusion proteins. ALK inhibition reduces proliferation of cells expressing the genetic alteration. Ceritinib also inhibits insulin-like growth factor 1 receptor (IGF-1R), insulin receptor (InsR), and ROS1. Ceritinib has demonstrated activity in crizotinib-resistant tumors in NSCLC xenograft models.

Absorption

AUC and Cmax increased 73% and 41%, respectively, when administered with a high-fat meal, and 58% and 43%, respectively when taken with a low-fat meal (when compared to fasting)

Distribution

4,230 L (following a single dose), with a small preferential distribution to red blood cells versus plasma

Metabolism

Primarily hepatic via CYP3A

Excretion

Feces (~92% with 68% as unchanged drug); urine (~1%)

Time to Peak

~4 to 6 hours

Half-Life Elimination

41 hours

Protein Binding

97% to human plasma proteins

Special Populations: Hepatic Function Impairment

Patients with hepatic impairment may have increased exposure.

Use: Labeled Indications

US labeling: Non-small cell lung cancer, metastatic: Treatment of patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib.

Canadian labeling: Non-small cell lung cancer, locally advanced or metastatic: Treatment of patients with ALK-positive locally advanced (not amenable to curative therapy) or metastatic NSCLC who have progressed on or are intolerant to crizotinib.

Contraindications

There are no contraindications listed in the manufacturer’s US labeling.

Canadian labeling: Hypersensitivity to ceritinib or any component of the formulation; congenital long QT syndrome or persistent Fridericia-corrected electrocardiogram interval (QTcF) of >500 msec.

Dosing: Adult

Note: Ceritinib is associated with a moderate emetic potential; antiemetics may be needed to prevent nausea and vomiting.

Non-small cell lung cancer (ALK-positive), metastatic: Oral: 750 mg once daily; continue until disease progression or unacceptable toxicity.

Missed doses: If a dose is missed, take the missed dose unless the next dose is due within 12 hours. If vomiting occurs, do not administer an additional dose, patients should continue with the next scheduled dose.

Dosage adjustment for concomitant therapy:

Strong CYP3A4 inhibitors:

US labeling: Avoid concomitant use of strong CYP3A inhibitors; if concurrent administration cannot be avoided, reduce ceritinib dose by approximately one-third (rounded to the nearest multiple of the 150 mg strength). After discontinuation of the strong CYP3A inhibitor, resume ceritinib therapy at the dose used prior to initiation of the CYP3A4 inhibitor.

Canadian labeling: Avoid concomitant use of strong CYP3A inhibitors.

Strong CYP3A4 inducers: Avoid concurrent use of strong CYP3A inducers (eg, carbamazepine, phenytoin, rifampin, and St John’s wort) during treatment with ceritinib.

Dosing: Geriatric

Refer to adult dosing.

Dosing: Renal Impairment

CrCl ≥30 to 90 mL/minute: No dosage adjustment is necessary.

CrCl <30 mL/minute: There are no dosage adjustments provided in the manufacturer’s labeling (has not been studied).

Dosing: Hepatic Impairment

Preexisting mild impairment (total bilirubin ≤ULN and AST >ULN or total bilirubin >1 to 1.5 times ULN and any AST): No dosage adjustment is necessary.

Preexisting moderate or severe impairment: There are no dosage adjustments provided in the manufacturer’s labeling (has not been studied). Ceritinib is primarily metabolized and eliminated hepatically; exposure is likely increased in patients with hepatic impairment.

Hepatotoxicity during treatment:

ALT or AST >5 times ULN with total bilirubin ≤2 times ULN (US labeling) or ≤1.5 times ULN (Canadian labeling): Interrupt therapy until recovery to baseline or ALT/AST ≤3 times ULN, then resume with a 150 mg dose reduction.

ALT or AST >3 times ULN with total bilirubin >2 times ULN in the absence of cholestasis or hemolysis: Permanently discontinue therapy.

Dosing: Adjustment for Toxicity

Note: Over half of patients initiating treatment required at least 1 dose reduction; the median time to the first dose reduction was 7 weeks. Discontinue if patients are unable to tolerate 300 mg daily.

Cardiac:

Bradycardia (heart rate <50 beats per minute [US labeling] or <60 beats per minute [Canadian labeling]):

US labeling: Symptomatic bradycardia (not life-threatening): Interrupt therapy and evaluate concomitant medications known to cause bradycardia. Upon recovery to asymptomatic bradycardia or to a heart rate ≥60 beats per minute, adjust the dose.

Canadian labeling: Interrupt therapy and evaluate for concomitant medication known to cause bradycardia. Upon recovery to asymptomatic bradycardia or to a heart rate ≥60 beats per minute:

If concomitant medication is identified and discontinued or its dose adjusted, reinitiate ceritinib at its previous dose.

If no concomitant medication is identified or if it is identified but not discontinued or not dose-adjusted, reinitiate ceritinib with a 150 mg dose reduction.

Symptomatic bradycardia (life-threatening or requiring intervention) in patients taking concomitant medications known to cause bradycardia/hypotension:

US labeling: Interrupt therapy until recovery to asymptomatic bradycardia or to a heart rate ≥60 beats per minute. If the concomitant medication can be adjusted or discontinued, resume ceritinib therapy with the dose reduced by 150 mg.

Canadian labeling: Interrupt therapy until recovery to asymptomatic bradycardia or to a heart rate ≥60 beats per minute. If concomitant medication can be discontinued or its dose adjusted, resume ceritinib with the dose reduced by 300 mg; monitor frequently; permanently discontinue ceritinib for recurrence.

Symptomatic bradycardia (life-threatening) in patients not taking concomitant medications known to cause bradycardia/hypotension: Permanently discontinue therapy.

QTc prolongation:

QTc interval >500 msec on at least 2 separate ECGs: Interrupt therapy until QTc interval is <481 msec or recovers to baseline if baseline QTc is ≥481 msec, then resume therapy with a 150 mg dose reduction.

QTc prolongation in combination with torsades de pointes, polymorphic ventricular tachycardia, or signs/symptoms of serious arrhythmia: Permanently discontinue therapy.

Gastrointestinal:

Severe or intolerable nausea, vomiting, or diarrhea (despite appropriate management): Interrupt therapy until improved, then resume treatment with a 150 mg dose reduction.

Lipase or amylase elevation >2 times ULN: Interrupt therapy and monitor serum lipase and amylase; upon recovery to <1.5 times ULN, resume treatment with a 150 mg dose reduction.

Metabolic: Persistent hyperglycemia >250 mg/dL (despite optimal antihyperglycemic therapy): Interrupt therapy until hyperglycemia is adequately controlled, then resume therapy with a 150 mg dose reduction. If hyperglycemia cannot be controlled, discontinue ceritinib permanently.

Pulmonary: Treatment-related interstitial lung disease/pneumonitis (any grade): Permanently discontinue therapy.

Administration

Ceritinib is associated with a moderate emetic potential; antiemetics may be needed to prevent nausea and vomiting.

Administer orally on an empty stomach (at least 2 hours before or 2 hours after a meal). Hazardous agent; use appropriate precautions for handling and disposal (meets NIOSH 2014 criteria).

The Canadian labeling recommends that the capsule not be crushed or chewed.

Warnings/Precautions

Concerns related to adverse effects:

• Bradycardia: Symptomatic bradycardia may occur; heart rate <50 beats/minute has occurred. If possible, avoid concurrent use with other agents known to cause bradycardia (eg, beta blockers, nondihydropyridine calcium channel blockers, clonidine, digoxin). Monitor heart rate and blood pressure regularly. If symptomatic bradycardia (not life-threatening) occurs, withhold treatment until recovery to asymptomatic bradycardia or to a heart rate of ≥60 beats/minute, evaluate concurrent medications, and adjust ceritinib dose. Permanently discontinue for life-threatening bradycardia due to ceritinib; if life-threatening bradycardia occurs and concurrent medications associated with bradycardia can be discontinued or dose adjusted, restart ceritinib at a reduced dose (with frequent monitoring).

• Gastrointestinal toxicity: Diarrhea, nausea, vomiting, or abdominal pain occurred in the majority of patients in clinical trials; over one-third of patients required dose reductions due to severe or persistent gastrointestinal toxicity. Manage symptoms medically with appropriate therapy (eg, antidiarrheals, antiemetics, fluid replacement) as indicated. May require therapy interruption and dosage reduction. Ceritinib is associated with a moderate emetic potential; antiemetics may be needed to prevent nausea and vomiting. If vomiting occurs, do not administer an additional dose; continue with the next scheduled dose.

• Hepatotoxicity: Hepatotoxicity has been observed in patients treated with ceritinib in clinical trials, including ALT levels >5 times ULN in over one-quarter of patients. Concurrent ALT elevations >3 times ULN with total bilirubin >2 times ULN (with normal alkaline phosphatase) occurred rarely. Monitor liver function tests (eg, ALT, AST, total bilirubin) monthly and as clinically necessary, more frequently in patients who develop transaminase abnormalities. May require therapy interruption, dosage reduction, and/or discontinuation.

• Hyperglycemia: Hyperglycemia, including grade 3 and 4 toxicity, has been observed in ceritinib-treated patients. The risk of grade 3 or 4 hyperglycemia increases significantly in diabetic patients or those with glucose intolerance; risk is also increased in patients receiving corticosteroids. Monitor fasting blood glucose levels at baseline and as clinically necessary, particularly in patients with diabetes. May require initiation or optimization of antihyperglycemic therapy. Temporarily interrupt therapy for hyperglycemia until adequately controlled; reduce dose upon recovery. If adequate glycemic control is not possible with medical management, permanently discontinue ceritinib.

• Pancreatitis: Although rare, pancreatitis (with fatality) has been reported. Grade 3 to 4 lipase and amylase elevations occurred in clinical trials. Monitor lipase and amylase prior to treatment and periodically during treatment as clinically necessary. May require treatment interruption and dose reduction.

• Pulmonary toxicity: Severe and life-threatening interstitial lung disease (ILD)/pneumonitis (some fatal) may occur. Monitor for signs/symptoms of pulmonary toxicity; permanently discontinue in patients diagnosed with treatment-related ILD/pneumonitis.

• QTc prolongation: QTc interval prolongation has occurred in clinical studies, and may be concentration-dependent. QT prolongation may lead to an increased risk for ventricular tachyarrhythmias (eg, torsades de pointes) or sudden death. Correct electrolyte abnormalities prior to initiating therapy. Periodically monitor ECG and electrolytes in patients with heart failure, bradyarrhythmias, electrolyte abnormalities, or who are taking medications known to prolong the QTc interval. May require treatment interruption, dosage reduction, or discontinuation. Avoid use in patients with congenital long QTc syndrome. The Canadian labeling contraindicates use in patients with congenital long QTc syndrome or persistent QTcF of >500 msec. Permanently discontinue in patients who develop QTc interval prolongation in combination with torsades de pointes or polymorphic ventricular tachycardia or signs/symptoms of serious arrhythmia.

Disease-related concerns:

• Hepatic impairment: Use with caution in patients with hepatic impairment (has not been studied in patients with moderate or severe impairment). Ceritinib is metabolized and eliminated hepatically; systemic exposure and toxicities may be increased in patients with hepatic dysfunction.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

• Drugs affecting gastric pH: In vitro studies indicate that ceritinib solubility and bioavailability may be decreased at higher pH; concurrent use with proton pump inhibitors, H2-receptor antagonists, or antacids has not been evaluated.

Special handling:

• Hazardous agents: Use appropriate precautions for handling and disposal (meets NIOSH 2014 criteria).

Monitoring Parameters

ALK positivity; CBC, renal function, liver function, fasting blood glucose (baseline and as clinically necessary), lipase and amylase (baseline and periodically as clinically necessary); electrolytes (baseline and periodically thereafter); cardiac monitoring (heart rate and QTc interval); blood pressure; signs/symptoms of gastrointestinal and pulmonary toxicity; signs/symptoms of pancreatitis.

Pregnancy Risk Factor

D

Pregnancy Considerations

Adverse events were observed in animal reproduction studies. Based on its mechanism of action, ceritinib may cause fetal harm if administered to a pregnant woman. Women of reproductive potential should use effective contraception during and for at least 2 weeks following therapy discontinuation. The Canadian labeling recommends women and men of reproductive potential use effective contraception during and for up to 3 months following therapy discontinuation.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience constipation, heartburn, loss of strength and energy, or lack of appetite. Have patient report immediately to prescriber signs of high blood sugar (confusion, fatigue, more thirst, hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), signs of a severe pulmonary disorder (lung or breathing problems like difficulty breathing, shortness of breath, or a cough that is new or worse), bruising, bleeding, tachycardia, bradycardia, abnormal heartbeat, angina, passing out, dizziness, burning or numbness feeling, severe abdominal pain, severe nausea, severe vomiting, severe diarrhea, change in balance, muscle weakness, or vision changes (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
