Pfizer’s XALKORI® Granted Regular FDA Approval
Standard of Care for Patients With Metastatic ALK-Positive Non-Small Cell Lung
NEW YORK -- November 21, 2013
Pfizer Inc. announced today that the U.S. Food and Drug Administration (FDA)
has granted Pfizer’s XALKORI^® (crizotinib) regular approval for the treatment
of patients with metastatic ALK-positive non-small cell lung cancer (NSCLC) as
detected by an FDA-approved test. XALKORI was previously granted accelerated
approval in August 2011 due to the critical need for new agents for people
living with ALK-positive NSCLC.
Lung cancer is the leading cause of cancer death worldwide^1 with an estimated
1.4 million deaths each year.^2 To date, globally more than 6,000 patients
have been treated with XALKORI, including those who received XALKORI in
clinical trials. ALK testing rates in the U.S. have increased more than 5-fold
from 11 percent before the XALKORI launch to more than 60 percent.^3
"XALKORI has dramatically changed the treatment landscape for patients with
advanced ALK-positive NSCLC," said Garry Nicholson, president and general
manager, Pfizer Oncology Business Unit. "Achievement of this milestone
underscores Pfizer’s commitment to provide physicians with effective cancer
therapies for their patients.”
The FDA’s action marks the conversion of an accelerated approval to regular
approval and is based on data from the pivotal Phase 3 PROFILE 1007
confirmatory trial comparing XALKORI to standard chemotherapy in previously
treated patients. The results of this study were recently published in the
June 20, 2013 issue of the New England Journal of Medicine.
In addition to the U.S., XALKORI has received approval in more than 60
countries, including EU, Canada, China, Korea, Japan and Australia.

XALKORI^® (crizotinib) Indication and Important Safety Information
XALKORI is a kinase inhibitor indicated for the treatment of patients with
metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic
lymphoma kinase (ALK)-positive as detected by an FDA-approved test.
Hepatotoxicity: Across three main clinical trials fatal hepatotoxicity
occurred in 0.2% of patients. Monitor with periodic liver testing. Temporarily
suspend, dose reduce, or permanently discontinue XALKORI.
Pneumonitis: Across three main clinical trials interstitial lung disease
(ILD)/pneumonitis occurred in 2% of patients. Permanently discontinue in
patients with ILD/pneumonitis.
QT Interval Prolongation: Across three main clinical trials QT interval
prolongation occurred in 2.7% of patients. Monitor with electrocardiograms and
electrolytes in patients who have a history of or predisposition for QTc
prolongation, or who are taking medications that prolong QT. Temporarily
suspend, dose reduce, or permanently discontinue XALKORI.
Bradycardia: Xalkori can cause bradycardia. Across three main clinical trials
11% of patients experienced a heart rate of less than 50 beats per minute.
Monitor heart rate and blood pressure regularly. Temporarily suspend, dose
reduce, or permanently discontinue XALKORI.
Embryofetal Toxicity: XALKORI can cause fetal harm when administered to a
pregnant woman. Women of childbearing potential should be advised to avoid
becoming pregnant while receiving XALKORI.
Adverse Reactions: Across three main clinical trials the most common adverse
reactions (≥25%) were vision disorders, nausea, diarrhea, vomiting,
constipation, edema, elevated transaminases, and fatigue.
In a phase 3 study in patients with ALK-positive metastatic NSCLC randomized
to XALKORI (n=172) or chemotherapy (n=171), serious adverse reactions were
reported in 37.2% of patients treated with XALKORI. The most frequent serious
adverse reactions reported in patients treated with XALKORI were pneumonia
(4.1%), pulmonary embolism (3.5%), dyspnea (2.3%), and ILD (2.9%). Fatal
adverse reactions in XALKORI-treated patients occurred in 9 (5%) patients,
consisting of: acute respiratory distress syndrome, arrhythmia, dyspnea, ILD,
pneumonia, pneumonitis, pulmonary embolism, respiratory failure, and sepsis.
Grade 3 or 4 events occurring at a higher incidence with XALKORI than with
chemotherapy and at greater than 2%, were syncope (3%), QT prolongation (3%),
and pulmonary embolism (5%). Elevation of ALT of any grade occurred in 76% of
patients and grade 3 or 4 in 17% of patients. Neutropenia of any grade
occurred in 49% of patients and grade 3 or 4 in 12% of patients. Lymphopenia
of any grade occurred in 51% of patients and grade 3 or 4 in 9% of patients.
Renal cysts occurred in 4% and neuropathy occurred in 19% of patients treated
Drug Interactions: Exercise caution with concomitant use of moderate CYP3A
inhibitors. Avoid grapefruit or grapefruit juice which may increase plasma
concentrations of crizotinib. Avoid concomitant use of strong CYP3A inducers
and inhibitors. Dose reduction may be needed for co-administered drugs that
are predominantly metabolized by CYP3A.
Nursing Mothers: Given the potential for serious adverse reactions in nursing
infants, consider whether to discontinue nursing or discontinue XALKORI.
Hepatic Impairment: XALKORI has not been studied in patients with hepatic
impairment. As crizotinib is extensively metabolized in the liver, hepatic
impairment is likely to increase plasma crizotinib concentrations. Use caution
in patients with hepatic impairment.
Renal Impairment: Administer XALKORI at a starting dose of 250 mg taken orally
once daily in patients with severe renal impairment (CLcr<30 mL/min) not
requiring dialysis. No starting dose adjustment is needed for patients with
mild and moderate renal impairment.
