exceeded, the patient can only be included after initiation of appropriate lipid
lowering medication at any point prior to the initiation of therapy

=< 1.5 on a stable dose of warfarin or on a stable dose of low molecular weight [LMW]
heparin for > 2 weeks at time of randomization)
Exclusion Criteria:
- Patient has history of using erlotinib or any other EGFR inhibitors (prior
C225/Cetuximab treatment is allowed if given with radiation therapy, but treatment
must have been completed at least 6 months prior to study entry)
- Patient has history of receiving RAD001 or any other mTOR inhibitors
- Patient is known to be allergic to any type of EGFR tyrosine kinase inhibitors or mTOR
inhibitors

systemic disease (e.g., unstable or uncompensated respiratory, cardiac, hepatic, or
renal disease); history of noncompliance to medical regimens
- Pregnant or breast-feeding women or adults of reproductive potential who are not using
effective birth control methods; adequate contraception must be used throughout the
trial and for 8 weeks after the last dose of study drug, by both sexes; (women of
childbearing potential must have a negative urine or serum pregnancy test within 7
days prior to administration of RAD001)
- Concomitant use of phenytoin, carbamazepine, rifampicin, barbiturates, or St John's
Wort; these medications can be discontinued one week prior to enrollment if medically
feasible
- Treatment on any other clinical protocols or with a non-approved or investigational
drug within 4 weeks before Day 1 of study treatment
- Any evidence of clinically active interstitial lung disease (patients with chronic
stable radiographic changes who are asymptomatic need not be excluded)
- Known active connective tissue disorders, such as lupus or scleroderma which, in the
opinion of the treating physician, may put the patient at high risk for radiation
toxicity
- Patients with known human immunodeficiency virus (HIV) infection and/or acquired
immune deficiency (AIDS)
- Patients with known multiple sclerosis
- Patients with nasopharyngeal carcinoma are excluded; other malignancies within the
past 3 years which actively require ongoing treatment except for treated carcinoma of
the cervix or basal or squamous cell carcinomas of the skin
- Patients should not receive immunization with attenuated live vaccines within one week
of study entry or during study period; close contact with those who have received
attenuated live vaccines should be avoided during treatment with RAD001; examples of
live vaccines include intranasal influenza, measles, mumps, rubella, oral polio,
Bacillus Calmette-Guerin (BCG), yellow fever, varicella and TY21a typhoid vaccines
- Patients who have any severe and/or uncontrolled medical conditions or other
conditions that could affect their participation in the study such as:
- Symptomatic congestive heart failure of New York heart Association Class III or
IV
- Unstable angina pectoris, symptomatic congestive heart failure, myocardial
infarction =< 6 months of start of study drug, serious uncontrolled cardiac
arrhythmia or any other clinically significant cardiac disease

(O2) saturation that is 88% or less at rest on room air
- Uncontrolled diabetes as defined by fasting serum glucose > 1.5 x ULN
- Active (acute or chronic) or uncontrolled severe infections
- Liver disease such as cirrhosis, chronic active hepatitis or chronic persistent
hepatitis; Note: A detailed assessment of hepatitis B/C medical history and risk
factors must be done at screening for all patients; hepatitis B virus (HBV)
deoxyribonucleic acid (DNA) and hepatitis C virus (HCV) ribonucleic acid (RNA)
polymerase chain reaction (PCR) testing are required at screening for all
patients with a positive medical history based on risk factors and/or
confirmation of prior HBV/HCV infection
- Steroid or supplemental oxygen required for exacerbations of chronic obstructive
lung disease
- Impairment of gastrointestinal function or gastrointestinal disease that may
significantly alter the absorption of RAD001 (e.g., ulcerative disease, uncontrolled
