            Contraindications

            None

            Cautions

            Drug-induced hepatotoxicity reported; 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 severity of adverse reaction, withhold drug with resumption at a reduced dose, or permanently discontinue therapy

            May cause severe, life-threatening, or fatal interstitial lung disease/pneumonitis

            May prolong QT interval; when possible, avoid use in patients with congenital long QT syndrome; conduct periodic monitoring with 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; based on severity of adverse reaction, withhold drug, with resumption at a reduced dose, or permanently discontinue therapy

            Hyperglycemia reported; monitor fasting serum glucose prior to the start of treatment and periodically thereafter as clinically indicated; initiate or optimize anti-hyperglycemic medications as indicated; based on severity, withhold then dose reduce, or permanently discontinue therapy

            Pancreatitis reported in less than 1% of patients receiving therapy; monitor lipase and amylase prior to initiating therapy and periodically thereafter as clinically indicated; based on severity of laboratory abnormalities, withhold and resume gradually

            Based on its mechanism of action, may cause fetal harm when administered to a pregnant woman (see Pregnancy)

            Severe, life-threatening, or fatal ILD/pneumonitis occurred; monitor for pulmonary symptoms indicative of ILD/pneumonitis; exclude other potential causes of ILD/pneumonitis, and permanently discontinue ceritinib in patients diagnosed with treatment-related ILD/pneumonitis

            Bradycardia

            • Avoid using drug in combination with other products known to cause bradycardia (eg, beta-blockers, non- dihydropyridine calcium channel blockers, clonidine, and digoxin) to the extent possible
            • Monitor heart rate and blood pressure regularly; based on severity of adverse reaction, withhold drug with resumption at a reduced dose upon resolution of bradycardia, or permanently discontinue therapy

            Gastrointestinal adverse reactions

            • Diarrhea, nausea, vomiting, or abdominal pain occurs in most patients, of which 14% have severe symptoms; monitor and manage patients using standards of care, including antidiarrheals, antiemetics, or fluid replacement, as indicated; based on severity of adverse drug reaction, withhold therapy with resumption at reduced dose
            • Data in the prescribing information reflect the safety of ceritinib 750 mg daily under fasted conditions in 925 patients with ALK-positive NSCLC across a pool of seven clinical studies at systemic exposures similar to the recommended dose of 450 mg with food
            • The incidence and severity of gastrointestinal adverse reactions were reduced for patients treated with 450 mg with food in a dose optimization study (ASCEND-8)
            • Monitor and manage patients using standard of care, including antidiarrheals, antiemetics, or fluid replacement, as indicated; withhold therapy if gastrointestinal adverse reaction is severe or intolerable and not responsive to antiemetics or antidiarrheals; upon improvement, resume therapy at a reduced dose

            Drug interactions overview

            • Also see Dosage Modifications
            • Coadministration with a strong CYP3A4/P-gp inhibitor (ketoconazole) increased systemic exposure of ceritinib
            • Avoid grapefruit and grapefruit juice consumption; may inhibit CYP3A
            • Coadministration with a strong CYP3A4/P-gp inducer (rifampin) decreased systemic exposure of ceritinib
            • Avoid concurrent use of CYP3A and CYP2C9 substrates known to have narrow therapeutic indexes or substrates primarily metabolized by CYP3A and CYP2C9 during treatment; if use of these medications is unavoidable, consider dose reduction of CYP3A substrates with narrow therapeutic indexes (eg, alfentanil, cyclosporine, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus) and CYP2C9 substrates with narrow therapeutic indexes (eg, phenytoin, warfarin)

            Pregnancy & Lactation

            Pregnancy

            Verify pregnancy status in females of reproductive potential prior to initiating therapy

            Based on animal studies and its mechanism of action, therapy can cause fetal harm when administered to a pregnant woman; limited data available on use in pregnant women are insufficient to inform a risk; administration to rats and rabbits during period of organogenesis at maternal plasma exposures below the recommended human dose caused increases in skeletal anomalies in rats and rabbits; advise pregnant women of potential risk to fetus

            Advise females of reproductive potential to use effective contraception during treatment with and for 6 months following completion of therapy

            Based on potential for genotoxicity, advise males with female partners of reproductive potential to use condoms during treatment and for 3 months following completion of therapy

            Lactation

            There are no data regarding presence of ceritinib or metabolites in human milk; effects of ceritinib on breastfed infant, or effects on milk production; because of potential for serious adverse reactions including gastrointestinal toxicity, hepatotoxicity, pneumonitis, bradycardia and pancreatitis, advise a woman not to breastfeed during treatment and for 2 weeks following completion of therapy

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            CERITINIB - ORAL

            (se-RI-ti-nib)

            COMMON BRAND NAME(S): Zykadia

            USES: Ceritinib is used to treat lung cancer. It is used for lung cancers that have a certain type of abnormal "ALK" gene. Ceritinib belongs to a class of drugs known as kinase inhibitors. It works by slowing or stopping the growth of cancer cells.

            HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking ceritinib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with food as directed by your doctor, usually once daily.The dosage is based on your medical condition, lab tests, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Drugs that reduce stomach acid (including antacids, proton pump inhibitors such as omeprazole, H2 blockers such as ranitidine) may make you absorb less ceritinib. This could make ceritinib work less well. Talk to your doctor or pharmacist if you are taking any of these medications.Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day.Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of serious side effects will increase.If you vomit after taking a dose, do not take another dose at that time. Take your next dose at the regular time.Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.

            SIDE EFFECTS: Diarrhea, nausea, vomiting, abdominal pain, loss of appetite, heartburn, constipation, or tiredness may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea, vomiting, or diarrhea. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects last or get worse, tell your doctor or pharmacist promptly.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Tell your doctor right away if you have any serious side effects, including: numbness/tingling, symptoms of liver problems (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine), vision changes (such as blurred vision, decreased vision), weakness.Get medical help right away if you have any very serious side effects, including: trouble breathing, cough with or without phlegm, fast/slow/irregular heartbeat, severe dizziness, fainting, seizure.This medication may rarely make your blood sugar rise, which can cause or worsen diabetes. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.Vomiting/diarrhea that doesn't stop may result in dehydration. Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual decreased urination, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.Ceritinib can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Tell your doctor right away if you develop any rash.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.

            PRECAUTIONS: Before taking this medication, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: diabetes or high blood sugar, liver problems.Ceritinib may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using ceritinib, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using ceritinib safely.This drug may rarely cause vision changes. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely. Limit alcoholic beverages.This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using ceritinib. Ceritinib may harm an unborn baby. Your doctor should order a pregnancy test before you start this medication.
