Additional dosage information:
Usual Adult Dose for Non-Small Cell Lung Cancer
250 mg orally twice a day until disease progression or unacceptable toxicity
Use: For the treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK) or ROS1-positive as detected by an FDA-approved test.
Renal Dose Adjustments
-Mild to moderate renal impairment (CrCl 30 to 89 mL/min): No adjustment recommended.
-Severe renal impairment (CrCl less than 30 mL/min) not requiring dialysis: 250 mg orally once a day
Liver Dose Adjustments
-Mild hepatic impairment (AST greater than upper limit of normal [ULN] and total bilirubin less than or equal to 1 times ULN or any AST and total bilirubin greater than 1 x ULN but less than or equal to 1.5 x ULN): No adjustment recommended.
-Moderate (any AST and total bilirubin greater than 1.5 x ULN and less than or equal to 3 x ULN) or severe (any AST and total bilirubin greater than 3 x ULN) hepatic impairment: Reduce the dose.
Dose Modifications for Adverse Reactions:
-First dose reduction: 200 mg orally twice a day
-Second dose reduction: 250 mg orally once a day
-Permanently discontinue therapy if unable to tolerate 250 mg orally once a day
-Grade 3: Withhold until recovery to Grade 2 or less, then resume at the same dose schedule.
-Grade 4: Withhold until recovery to Grade 2 or less, then resume at next lower dose.
-Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than 5 times upper limit of normal (ULN) with total bilirubin less than or equal to 1.5 times ULN: Withhold therapy until recovery to baseline or less than or equal to 3 x ULN, then resume at next lower dosage.
-ALT or AST elevation greater than 3 x ULN with concurrent total bilirubin elevation greater than 1.5 x ULN (in the absence of cholestasis or hemolysis): Permanently discontinue therapy.
INTERSTITIAL LUNG DISEASE (ILD)/PNEUMONITIS:
-Any grade drug-related ILD/pneumonitis: Permanently discontinue therapy.
-QTc greater than 500 ms on at least 2 separate ECGs: Withhold therapy until recovery to baseline or to a QTc less than 481 ms, then resume at reduced dose.
-QTc greater than 500 ms or greater than or equal to 60 ms change from baseline with Torsade de pointes, polymorphic ventricular tachycardia, or signs/symptoms of serious arrhythmia: Permanently discontinue therapy.
-Symptomatic, may be severe and medically significant, medical intervention indicated: Withhold therapy until recovery to asymptomatic bradycardia or to a heart rate of 60 bpm or above; if concomitant medication contributing to bradycardia is identified and it's discontinued or dose adjusted, resume therapy at previous dose; if no contributing medication is identified or that medication is not discontinued or dose adjusted, resume therapy at a reduced dose upon recovery to asymptomatic bradycardia or to a heart rate of 60 bpm or above.
-Life-threatening, urgent intervention indicated: Permanently discontinue therapy if no contributing concomitant medication is identified. If contributing concomitant medication is identified and discontinued or its dose is adjusted, resume therapy at 250 mg once a day with frequent monitoring. In case of recurrence, permanently discontinue therapy.
SEVERE VISION LOSS (GRADE 4 OCULAR DISORDER): Discontinue therapy during evaluation of severe vision loss.
Dosage Modification for Concomitant Use of Strong CYP450 3A Inhibitors:
-Avoid concomitant use of strong CYP450 3A inhibitors; if concomitant use is unavoidable, reduce the dose of crizotinib to 250 mg orally once daily.
-After discontinuation of a strong CYP450 3A inhibitor, resume the crizotinib dose used prior to initiating the strong CYP450 3A inhibitor.
Safety and efficacy have not been established in patients younger than 18 years.
