Ceritinib
Indications
Ceritinib is indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.
Pharmacology
Ceritinib is a kinase inhibitor. Targets of Ceritinib inhibition identified in either biochemical or cellular assays at clinically relevant concentrations include ALK, insulin- like growth factor 1 receptor (IGF-1R), insulin receptor (InsR), and ROS1. Among these, Ceritinib is most active against ALK. Ceritinib inhibited autophosphorylation of ALK, ALK-mediated phosphorylation of the downstream signaling protein STAT3, and proliferation of ALK dependent cancer cells in in vitro and in vivo assays.
Absorption: After a single oral administration of Ceritinib in patients, peak plasma levels (Cmax) of Ceritinib were achieved at approximately 4 to 6 hours, and AUC and C max increased dose proportionally over 50 to 750 mg under fasted conditions. The absolute bioavailability of Ceritinib has not been determined.
Distribution: Ceritinib is 97% bound to human plasma proteins, independent of drug concentration. The apparent volume of distribution is 4230 L following a single 750 mg fasted Ceritinib dose in patients. Ceritinib also has a slight preferential distribution to red blood cells, relative to plasma, with a mean in vitro blood-to-plasma ratio of 1.35.
Elimination: Following a single 750 mg fasted Ceritinib dose, the geometric mean apparent plasma terminal half life (t½) of Ceritinib was 41 hours in patients. Ceritinib demonstrates nonlinear PK over time. The geometric mean apparent clearance of Ceritinib was lower at steady-state (33.2 L/h) after 750 mg daily dosing than after a single 750 mg dose (88.5 L/h).
Metabolism: In vitro studies demonstrated that CYP3A was the major enzyme involved in the metabolic clearance of Ceritinib. Following oral administration of a single 750 mg radiolabeled Ceritinib dose under fasted conditions, Ceritinib as the parent compound was the main circulating component (82%) in human plasma.
Excretion: Following oral administration of a single 750 mg radiolabeled Ceritinib dose under fasted conditions, 92.3% of the administered dose was recovered in the feces (with 68% as unchanged parent compound) while 1.3% of the administered dose was recovered in the urine.

Dosage & Administration
Patients should be selected for treatment of metastatic NSCLC with Ceritinib based on the presence of ALK positivity in tumor specimens. The recommended dose of Ceritinib is 450 mg orally once daily with food until disease progression or unacceptable toxicity. If a dose of Ceritinib is missed, that dose should be made up unless the next dose is due within 12 hours. If vomiting occurs during the course of treatment, an additional dose should not be administered and the next scheduled dose of Ceritinib should be continued. Or, as directed by the registered physician.

Interaction
Effect of Other Drugs on Ceritinib: Strong CYP3A Inhibitors: A strong CYP3A4/P-gp inhibitor (ketoconazole) increased the systemic exposure of Ceritinib so it should be avoided. If concomitant use of strong CYP3A inhibitors including certain antivirals (e.g., ritonavir), macrolide antibiotics (e.g., telithromycin), antifungals (e.g., ketoconazole), and nefazodone is unavoidable, the Ceritinib dose should be reduced by approximately one third, rounded to the nearest multiple of the 150 mg dosage strength. After discontinuation of a strong CYP3A inhibitor, the Ceritinib dose should be resumed that was taken prior to initiating the strong CYP3A inhibitor. Grapefruit and grapefruit juice should not be consumed as they may inhibit CYP3A.
Strong CYP3A Inducers: A strong CYP3A4/P-gp inducer (Rifampin) decreased the systemic exposure of Ceritinib. Concurrent use of strong CYP3A inducers (e.g., Carbamazepine, Phenytoin, Rifampin, and St. John's Wort) should be avoided during treatment with Ceritinib.
Effect of Ceritinib on Other Drugs: CYP3A Substrates: Ceritinib increased the systemic exposure of a sensitive CYP3A substrate (Midazolam) so it should be avoided. If concomitant use is unavoidable, dose reduction of the sensitive CYP3A substrates should be considered. If Ceritinib is coadministered with other CYP3A substrates, it should be referred to the CYP3A substrate labeling for dosage recommendation with strong CYP3A inhibitors.
CYP2C9 Substrates: Ceritinib increased the systemic exposure of a CYP2C9 substrate (Warfarin). The frequency of INR monitoring should be increased if coadministration with warfarin is unavoidable as the anti-coagulant effect of Warfarin may be enhanced. Coadministration of Ceritinib should be avoided with CYP2C9 substrates for which minimal concentration changes may lead to serious toxicities. If concomitant use of such CYP2C9 substrates is unavoidable, dose reduction should be considered for the coadministered CYP2C9 substrates.
Strong CYP3A Inducers: A strong CYP3A4/P-gp inducer (Rifampin) decreased the systemic exposure of Ceritinib. Concurrent use of strong CYP3A inducers (e.g., Carbamazepine, Phenytoin, Rifampin, and St. John's Wort) should be avoided during treatment with Ceritinib.

Pregnancy & Lactation
Ceritinib can cause fetal harm when administered to a pregnant woman. If it is used during pregnancy or if the patient becomes pregnant while taking it, the patient should be apprised of the potential hazard to the fetus. There are no data regarding the presence of Ceritinib or its metabolites in human milk, the effects of Ceritinib on the breastfed infant, or its effects on milk production. Because of the potential for serious adverse reactions including gastrointestinal adverse reactions, hepatotoxicity, pneumonitis, bradycardia and pancreatitis, a woman should be advised not to breastfeed during treatment with Cerinib and for 2 weeks following completion of therapy.
Precautions & Warnings
Gastrointestinal Adverse Reactions: Severe gastrointestinal toxicity occurred in patients treated with Ceritinib 750 mg under fasted conditions. Diarrhea, nausea, vomiting, or abdominal pain occurred in 95% of 925 patients, including severe cases (Grade 3 or 4) in 14% of patients treated with Ceritinib across clinical studies. Diarrhea, nausea, vomiting, or abdominal pain leading to dose interruptions or reductions occurred in 36% of patients and leading to treatment discontinuation occurred in 1.6% of patients. Patients should be monitored and managed using standards of care, including antidiarrheals, antiemetics, or fluid replacement, as indicated. Based on the severity of the adverse drug reaction, Ceritinib should be withheld with resumption at a reduced dose.
Hepatotoxicity: Drug-induced hepatotoxicity occurred in patients treated with Ceritinib. Elevations in alanine aminotransferase (ALT) greater than 5 times the upper limit of normal (ULN) occurred in 28% and elevations in aspartate aminotransferase (AST) greater than 5 times ULN occurred in 16% of 925 patients across clinical studies. Concurrent elevations in ALT greater than 3 times the ULN and total bilirubin greater than 2 times the ULN, with alkaline phosphatase less than 2 times the ULN occurred in 0.3% of patients across clinical studies. Approximately 1.0% of patients required permanent discontinuation due to hepatotoxicity. It should be monitor with liver laboratory tests including ALT, AST, and total bilirubin once a month and as clinically indicated, with more frequent testing in patients who develop transaminase elevations. Based on the severity of the adverse drug reaction, Ceritinib should be withheld with resumption at a reduced dose, or permanently discontinue Ceritinib.
Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, or fatal ILD/pneumonitis occurred in patients treated with Ceritinib. Across clinical studies, ILD/pneumonitis was reported in 2.4% of 925 patients treated with Ceritinib. National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Grade 3 or 4 ILD/pneumonitis was reported in 1.3% of patients, with fatal events reported in 0.2% of patients. Ten patients (1.1%) discontinued Ceritinib across clinical studies due to ILD/pneumonitis. Patients should be monitored for pulmonary symptoms indicative of ILD/pneumonitis.
QT Interval Prolongation: QTc interval prolongation, which may lead to an increased risk for ventricular tachyarrhythmia (e.g., torsades de pointes) or sudden death, occurred in patients treated with Ceritinib. Across clinical studies, 6% of 919 patients with at least one post-baseline ECG assessment experienced a QTc interval increase over baseline of greater than 60 msec. Approximately 1.3% of patients taking Ceritinib 750 mg fasted were found to have a QTc greater than 500 msec. When possible, use of Ceritinib should be avoided in patients with congenital long QT syndrome. Periodic monitoring should be conducted with electrocardiograms (ECGs) and electrolytes in patients with congestive heart failure, bradyarrhythmias, electrolyte abnormalities, or those who are taking medications that are known to prolong the QTc interval.
Hyperglycemia: Hyperglycemia occurred in patients receiving Ceritinib. Across clinical studies, CTCAE Grade 3 or 4 hyperglycemia, based on laboratory values, occurred in 13% of 925 patients. Fasting serum glucose should be monitored prior to the start of Ceritinib treatment and periodically thereafter as clinically indicated. Based on the severity of the adverse drug reaction, Ceritinib should be withheld until hyperglycemia is adequately controlled, then resume Ceritinib at a reduced dose.
Bradycardia: Bradycardia occurred in patients receiving Ceritinib. Across clinical studies, sinus bradycardia, defined as a heart rate of less than 50 beats per minute (bpm), was noted as a new finding in 1% of 925 patients. Bradycardia was reported as an adverse drug reaction in 1% of patients. No patient required discontinuation and 0.1% required interruption with subsequent dose reduction for bradycardia. Using Ceritinib should be avoided in combination with other agents known to cause bradycardia (e.g., beta-blockers, nondihydropyridine calcium channel blockers, clonidine, and digoxin) to the extent possible. Heart rate and blood pressure should be regularly monitored. In cases of symptomatic bradycardia that is not life threatening, Ceritinib should be withheld until recovery to asymptomatic bradycardia or to a heart rate of 60 bpm or above, evaluate the use of concomitant medications, and adjust the dose of Ceritinib.
Pancreatitis: Pancreatitis occurred in patients receiving Ceritinib. Pancreatitis, including one fatality, occurred in less than 1% of patients receiving Ceritinib in clinical studies. CTCAE Grade 3 or 4 elevations of amylase occurred in 7% of patients receiving Ceritinib across clinical studies, while CTCAE Grade 3 or 4 elevations of lipase occurred in 14% of patients. Lipase and amylase should be monitored prior to the start of Ceritinib treatment and periodically thereafter as clinically indicated. Based on the severity of the laboratory abnormalities, Ceritinib should be withheld with resumption at a reduced dose.
Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animal studies, Ceritinib can cause fetal harm when administered to a pregnant woman. Pregnant women should be advised of the potential risk to a fetus. Females of reproductive potential should be advised to use effective contraception during treatment with Ceritinib and for 6 months following completion of therapy. Based on the potential for genotoxicity, males with female partners of reproductive potential should be advised to use condoms during treatment with Ceritinib and for 3 months following completion of therapy.
