must have been completed at least 6 months prior to study entry)

- Patient has history of receiving RAD001 or any other mTOR inhibitors

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

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
