Patient Information:
PATIENT COUNSELING INFORMATION
See FDA-approved patient labeling (Patient Information)
Diarrhea : Advise patients that diarrhea occurs in nearly all patients who receive
GILOTRIF. Inform patients that diarrhea may result in dehydration and renal
impairment if not treated. Advise patients to notify their physician if diarrhea
develops and to seek medical attention promptly for severe or persistent
diarrhea [see Warnings and Precautions
Bullous and Exfoliative Skin Disorders

sunscreen while taking GILOTRIF
Interstitial Lung Disease
Advise patients to immediately report any new or worsening lung symptoms,
or any combination of the following symptoms:
trouble breathing or shortness of breath, cough, fever
Hepatic Toxicity
Advise patients that they will need to undergo liver function monitoring periodically.
Advise patients to immediately report any symptoms of a liver problem
(e.g., skin or the whites of eyes turn yellow, urine turns dark or brown (tea colored),
pain on the right side of stomach, bleed or bruise more easily than normal, lethargy)
Keratitis
Advise patients to immediately report eye problems (e.g., eye pain, swelling, redness
blurred vision, or other vision changes)

Instructions for Taking GILOTRIF
Advise patients to take GILOTRIF on an empty stomach at least 1 hour before
or 2 hours after eating
Advise patients not to take a missed dose within 12 hours of the next dose.
„h Embryofetal Toxicity

Pharmacology/ Pharmacokinetics:
CLINICAL PHARMACOLOGY
1. Mechanism of Action
Afatinib covalently binds to the kinase domains of EGFR (ErbB1), HER2 (ErbB2),
and HER4 (ErbB4) and irreversibly inhibits tyrosine kinase autophosphorylation,
resulting in downregulation of ErbB signaling.
Afatinib demonstrated inhibition of autophosphorylation and in vitro proliferation
of cell lines expressing wild-type EGFR or those expressing selected
EGFR exon 19 deletion mutations or exon 21 L858R mutations, including some
with a secondary T790M mutation, at afatinib concentrations achieved,
at least transiently, in patients. In addition, afatinib inhibited in vitro proliferation
of cell lines overexpressing HER2.
2. Pharmacokinetics
Absorption and Distribution
Following oral administration of GILOTRIF tablets, time to peak afatinib plasma
concentrations (Tmax) is 2 to 5 hours. Maximum concentration (Cmax) and area
under the concentration-time curve from time zero to infinity (AUC0-‡) value
increased slightly more than dose proportional in the range of 20 to 50 mg.
The geometric mean relative bioavailability of 20 mg GILOTRIF tablets was 92%
as compared to an oral solution. In vitro binding of afatinib to human plasma
proteins is approximately 95%.
A high-fat meal decreased Cmax by 50% and AUC0-‡ by 39% relative to the
fasted condition
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1. Pregnancy
Pregnancy Category D
Risk Summary
Based on its mechanism of action, GILOTRIF can cause fetal harm when administered to
a pregnant woman. Afatinib was embryotoxic and, in animals with maternal toxicity,
led to abortions at late gestational stages in rabbits at doses of 5 mg/kg
(approximately 0.2 times the exposure by AUC at the recommended human dose
of 40 mg daily) or greater.
If this drug is used during pregnancy, or if the patient becomes pregnant while
taking this drug, the patient should be apprised of the potential hazard to the fetus
2. Nursing Mothers
It is not known whether afatinib is present in human milk. Afatinib was present
in the milk of lactating rats at concentrations 80-150 times higher than those
found in plasma from 1 to 6 hours after administration.
Because many drugs are present in human milk and because of the potential
for serious adverse reactions in nursing infants from GILOTRIF, a decision
should be made whether to discontinue nursing or to discontinue the drug,
taking into account the importance of the drug to the mother.
3. Pediatric Use
Saf.ety and effectiveness of GILOTRIF in pediatric patients have not been established.
4. Geriatric Use
Of the 3865 patients in the clinical studies of GILOTRIF, 32% of patients were 65 years
and older, while 7% were 75 years and older. No overall differences in safety
were observed between patients 65 years and over and younger patients.
