Description
Indications
Pharmacology
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
Interaction
Strong CYP3A Inducers: A strong CYP3A4/P-gp inducer (Rifampin) decreased the systemic exposure of Cerinib. Concurrent use of strong CYP3A inducers (e.g., Carbamazepine, Phenytoin, Rifampin, and St. John’s Wort) should be avoided during treatment with Cerinib.
Effect of Cerinib on Other Drugs: CYP3A Substrates: Cerinib 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 Cerinib is coadministered with other CYP3A substrates, it should be referred to the CYP3A substrate labeling for dosage recommendation with strong CYP3A inhibitors.
CYP2C9 Substrates: Cerinib 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 Cerinib 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.

Precautions & Warnings
Hepatotoxicity: Drug-induced hepatotoxicity occurred in patients treated with Cerinib. 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, Cerinib should be withheld with resumption at a reduced dose, or permanently discontinue Cerinib.
Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, or fatal ILD/pneumonitis occurred in patients treated with Cerinib. Across clinical studies, ILD/pneumonitis was reported in 2.4% of 925 patients treated with Cerinib. 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 Cerinib 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 Cerinib. 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 Cerinib 750 mg fasted were found to have a QTc greater than 500 msec. When possible, use of Cerinib 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 Cerinib. 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 Cerinib treatment and periodically thereafter as clinically indicated. Based on the severity of the adverse drug reaction, Cerinib should be withheld until hyperglycemia is adequately controlled, then resume Cerinib at a reduced dose.
Bradycardia: Bradycardia occurred in patients receiving Cerinib. 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 Cerinib 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, Cerinib 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 Cerinib.
Pancreatitis: Pancreatitis occurred in patients receiving Cerinib. Pancreatitis, including one fatality, occurred in less than 1% of patients receiving Cerinib in clinical studies. CTCAE Grade 3 or 4 elevations of amylase occurred in 7% of patients receiving Cerinib 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 Cerinib treatment and periodically thereafter as clinically indicated. Based on the severity of the laboratory abnormalities, Cerinib should be withheld with resumption at a reduced dose.
Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animal studies, Cerinib 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 Cerinib 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 Cerinib and for 3 months following completion of therapy.
Use in Special Populations
Males: Based on the potential for genotoxicity, males with female partners of reproductive potential should be advised to use condoms during treatment with Cerinib and for 3 months following completion of therapy.
Pediatric Use: The safety and effectiveness of Cerinib in pediatric patients have not been established.
Geriatric Use: Of the 925 patients in clinical studies of Cerinib, 18% were 65 years or older, while 5% were 75 years or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.
Hepatic Impairment: For patients with severe hepatic impairment (Child-Pugh C), the dose of Cerinib should be reduced by approximately one-third, rounded to the nearest multiple of the 150 mg dosage strength. No dose adjustment is recommended in patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment.
