Dosage Modifications

Dose reduction increments

  • Starting dose: 750 mg qDay
  • First dose reduction: 600 mg qDay
  • Second dose reduction: 450 mg qDay
  • Third dose reduction: 300 mg qDay
  • Unable to tolerate 300 mg/day: Discontinue

Coadministration with strong CYP3A4 inhibitors

  • Avoid concurrent use of strong CYP3A inhibitors during treatment
  • If coadministration with a strong CYP3A inhibitor is unavoidable, reduce the dose by ~one-third, rounded to the nearest multiple of the 150 mg dosage strength
  • After discontinuation of a strong CYP3A inhibitor, resume the dose that was taken prior to initiating the strong CYP3A4 inhibitor

ALT/AST elevation

  • ALT/AST increase >5 x ULN with total bilirubin ≤2 x ULN: Withhold until recovery to baseline or ≤3 x ULN, then resume with 150-mg dose reduction
  • ALT/AST increase >3 x ULN with total bilirubin >2 x ULN in absence of cholestasis or hemolysis: Permanently discontinue

Gastrointestinal

  • Lipase or amylase increase ≥2 x ULN: Withhold and monitor serum lipase and amylase; resume when improved with 150-mg dose reduction
  • Severe or intolerable nausea, vomiting, or diarrhea despite optimal antiemetic therapy: Withhold until improved, then resume with 150-mg dose reduction

Hyperglycemia

  • Persistent hyperglycemia >250 mg/dL despite optimal antihyperglycemic therapy: Withhold ceritinib until hyperglycemia is adequately controlled, then resume with 150-mg dose reduction
  • If adequate hyperglycemic control cannot be achieved with optimal medical management, discontinue ceritinib

Pneumonitis

  • Any grade treatment-related ILD/pneumonitis: Permanently discontinue

Prolonged QT interval

  • QT interval >500 msec (on at least 2 separate ECGs): Withhold until QTc interval <481 msec or recovery to baseline if baseline QTc ≥481 msec, then resume with a 150-mg dose reduction
  • QTc interval prolongation in combination with torsade de pointes or polymorphic ventricular tachycardia or signs/symptoms of serious arrhythmia: Permanently discontinue

Bradycardia

  • Symptomatic (not life-threatening): Withhold until recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm; evaluate concomitant medications known to cause bradycardia, and adjust the dose
  • Clinically significant requiring intervention or life-threatening in patients taking concomitant drug also known to cause bradycardia: Withhold until recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm; if concomitant medication can be adjusted or discontinued, resume with a 150-mg dose reduction, with frequent monitoring
  • Life-threatening bradycardia in patient who are not taking a concomitant medication also known to cause bradycardia or known to cause hypotension: Permanently discontinue

            Also see Dosage Modifications

            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

            Drug-induced hepatotoxicity reported; monitor ALT, AST, and total bilirubin once monthly and as clinically indicated

            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; periodically monitor ECG and electrolytes in patients with congestive heart failure, bradyarrhythmias, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval

            Hyperglycemia reported; monitor fasting glucose prior to treatment and periodically thereafter as clinically indicated; initiate or optimize anti-hyperglycemic medications as indicated; 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

            Bradycardia reported; avoid coadministration with other drugs known to cause bradycardia

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

            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

            Pregnancy & Lactation

            Pregnancy

            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 of 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

             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.
