Description
11 DESCRIPTION Crizotinib is a kinase inhibitor. The molecular formula for crizotinib is C 21 H 22 Cl 2 FN 5 O and the molecular weight is 450.34 daltons. Crizotinib is described chemically as ( R )-3-[1-(2,6-Dichloro-3-fluorophenyl)ethoxy]-5-[1-(piperidin-4-yl)-1 H -pyrazol-4-yl]pyridin-2-amine. The chemical structure of crizotinib is shown below: Crizotinib is a white to pale-yellow powder with a pKa of 9.4 (piperidinium cation) and 5.6 (pyridinium cation). The solubility of crizotinib in aqueous media decreases over the range pH 1.6 to pH 8.2 from greater than 10 mg/mL to less than 0.1 mg/mL. The log of the distribution coefficient (octanol/water) at pH 7.4 is 1.65. Capsules: XALKORI (crizotinib) capsules for oral administration are supplied as printed hard-shell capsules containing 250 mg or 200 mg of crizotinib together with colloidal silicon dioxide, microcrystalline cellulose, anhydrous dibasic calcium phosphate, sodium starch glycolate, magnesium stearate, and hard gelatin capsule shells as inactive ingredients. The pink opaque capsule shell components contain gelatin, titanium dioxide, and red iron oxide. The white opaque capsule shell components contain gelatin and titanium dioxide. The printing ink contains shellac, propylene glycol, strong ammonia solution, potassium hydroxide, and black iron oxide. Oral Pellets: XALKORI (crizotinib) oral pellets for oral administration are supplied as 20 mg, 50 mg, 150 mg of crizotinib contained in hard gelatin capsules. The inactive ingredients in the uncoated pellets are poloxamer and stearyl alcohol.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling:
Hepatotoxicity [see Warnings and Precautions (5.1) ] Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.2) ] QT Interval Prolongation [see Warnings and Precautions (5.3) ] Bradycardia [see Warnings and Precautions (5.4) ] Severe Visual Loss [see Warnings and Precautions (5.5) ] Gastrointestinal Toxicity in Pediatric and Young Adult Patients with ALCL or Pediatric Patients with IMT [see Warnings and Precautions (5.6) ] The most common adverse reactions (≥25%) in adult patients with NSCLC are vision disorders, nausea, diarrhea, vomiting, edema, constipation, elevated transaminases, fatigue, decreased appetite, upper respiratory infection, dizziness, and neuropathy. ( 6.1 ) The most common adverse reactions (≥35%) in patients with ALCL are diarrhea, vomiting, nausea, vision disorder, headache, musculoskeletal pain, stomatitis, fatigue, decreased appetite, pyrexia, abdominal pain, cough, and pruritus. Grade 3–4 laboratory abnormalities (≥15%) are neutropenia, lymphopenia, and thrombocytopenia. ( 6.1 ) The most common adverse reactions (≥35%) in adult patients with IMT are vision disorders, nausea, and edema. ( 6.1 ) The most common adverse reactions (≥35%) in pediatric patients with IMT are vomiting, nausea, diarrhea, abdominal pain, rash, vision disorder, upper respiratory tract infection, cough, pyrexia, musculoskeletal pain, fatigue, edema, constipation, and headache.

The data in the Warnings and Precautions reflect exposure to XALKORI in 1719 patients with NSCLC who received XALKORI 250 mg twice daily enrolled on Studies 1 (including an additional 109 patients who crossed over from the control arm), 2, 3, a single-arm trial (n=1063) of ALK-positive NSCLC, and an additional ALK-positive NSCLC expansion cohort of a dose finding study (n=154). The data also reflect exposure to XALKORI in 121 patients ages 1 to ≤21 years with relapsed or refractory tumors, including 26 patients with systemic ALCL and 14 pediatric patients with IMT, in a single-arm trial (Study ADVL0912). The data are also described for 7 adult patients with IMT treated with XALKORI in a single-arm trial (Study A8081013). ALK- or ROS1-Positive Metastatic NSCLC The data described below is based primarily on 343 patients with ALK-positive metastatic NSCLC who received XALKORI 250 mg orally twice daily from 2 open-label, randomized, active-controlled trials (Studies 1 and 2). The safety of XALKORI was also evaluated in 50 patients with ROS1-positive metastatic NSCLC from a single-arm study (Study 3). The most common adverse reactions (≥25%) of XALKORI in patients with NSCLC are vision disorders, nausea, diarrhea, vomiting, edema, constipation, elevated transaminases, fatigue, decreased appetite, upper respiratory infection, dizziness, and neuropathy. Previously Untreated ALK-Positive Metastatic NSCLC - Study 1 (PROFILE 1014) The data in Table 9 are derived from 340 patients with ALK-positive metastatic NSCLC who had not received previous systemic treatment for advanced disease who received treatment in a randomized, multicenter, open-label, active-controlled trial (Study 1). Patients in the XALKORI arm (n=171) received XALKORI 250 mg orally twice daily until documented disease progression, intolerance to therapy, or the investigator determined that the patient was no longer experiencing clinical benefit. A total of 169 patients in the chemotherapy arm received pemetrexed 500 mg/m 2 with...Drug Interactions
7 DRUG INTERACTIONS
Strong CYP3A Inhibitors: Avoid concomitant use. ( 2.9 , 7.1 ) Strong CYP3A Inducers: Avoid concomitant use. ( 7.1 ) CYP3A Substrates: Avoid concomitant use with CYP3A substrates, where minimal concentration changes may lead to serious adverse reactions. ( 7.2 ) 7.1 Effect of Other Drugs on XALKORI Strong or Moderate CYP3A Inhibitors Concomitant use of crizotinib with strong CYP3A inhibitors increases crizotinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions of XALKORI. Avoid concomitant use of strong CYP3A inhibitors. If concomitant use of strong CYP3A inhibitors is unavoidable, reduce the XALKORI dosage [see Dosage and Administration (2.9) ] . Avoid grapefruit or grapefruit juice which may also increase plasma concentrations of crizotinib. Use caution with concomitant use of moderate CYP3A inhibitors. Strong CYP3A Inducers Concomitant use of crizotinib with strong CYP3A inducers decreases crizotinib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may decrease the efficacy of XALKORI. Avoid concomitant use of strong CYP3A inducers. 7.2 Effect of XALKORI on Other Drugs CYP3A Substrates Concomitant use of crizotinib increases plasma concentrations of CYP3A substrates [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions of these substrates. Avoid concomitant use of XALKORI with CYP3A substrates where minimal concentration changes may lead to serious adverse reactions. If concomitant use of XALKORI is unavoidable, decrease the CYP3A substrate dosage in accordance with approved product labeling. 7.3 Drugs That Prolong the QT Interval XALKORI can prolong the QT/QTc interval. Avoid concomitant use of XALKORI with drugs that prolong the QT interval [see Warnings and Precautions (5.3) , Clinical Pharmacology (12.2) ] . 7.4 Drugs That Cause Bradycardia XALKORI can cause bradycardia. Avoid concomitant use of XALKORI with drugs that cause bradycardia (e.g., beta-blockers, non-dihydropyridine calcium channel blockers, clonidine, and digoxin) [see Warnings and Precautions (5.4) ] .Contraindications

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action, XALKORI can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of XALKORI in pregnant women. In animal reproduction studies, oral administration of crizotinib to pregnant rats during organogenesis at exposures similar to those expected with the maximum recommended human dose resulted in embryotoxicity and fetotoxicity (see Data ) . Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Crizotinib was administered to pregnant rats and rabbits during organogenesis to study the effects on embryo-fetal development. Postimplantation loss was increased at doses ≥50 mg/kg/day (approximately 0.6 times the recommended human dose based on AUC) in rats. No teratogenic effects were observed in rats at doses up to the maternally toxic dose of 200 mg/kg/day (approximately 2.7 times the recommended human dose based on AUC) or in rabbits at doses of up to 60 mg/kg/day (approximately 1.6 times the recommended human dose based on AUC), though fetal body weights were reduced at these doses.
