Trial Information

A Phase II Study of Letrozole and RAD001 (Everolimus) in Patients With Advanced or Recurrent Endometrial Cancer


The Study Drugs:

Everolimus is designed to stop cancer cells from multiplying. It may also stop the growth
of new blood vessels that help tumor growth, which may cause the tumor cells to die.

Letrozole is designed to block chemical pathways that are necessary for tumor growth.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will take 2 pills of
everolimus by mouth 1 time every day. You should not open everolimus until you are about to
take it because it absorbs moisture and is sensitive to light. You will also take 1 pill of
letrozole by mouth 1 time every day. You should take letrozole at the same time as
everolimus.

Everolimus should be taken the same time every day on an empty stomach (fasting state) or
after no more than a light, fat-free meal. You should wait at least 6 hours after a eating
a regular (not fat-free meal) before taking everolimus. You should not eat fatty foods for
at least 1 hour after taking everolimus.

If you cannot swallow the tablets, the tablets should be dissolved in a glass of about 2
tablespoons of water just before being taken. The tablets should then be stirred gently
(for a maximum of 7 minutes) until the tablets are dissolved. The contents should then be
drunk. If you vomit after taking the study drug, you should not take another tablet that
day. If you forgot to take the drug one day, you should not take an extra dose the next day
but instead contact your doctor for advice.

You will be given a diary where you will record the pills you take each day. You must bring
this diary to each visit.

While you are on study, you should avoid grapefruit, grapefruit juice, and other products
containing grapefruit. There are also certain drugs you cannot take during this study. You
should not take any drugs during the study without asking the study doctor first.

Study Visits:

Every 4 weeks, the following tests and procedures will be performed:

- You will have a physical exam, including measurement of your weight and vital signs
(blood pressure, heart rate, breathing rate, and temperature).

- Your performance status will be recorded.

- Blood (about 2 tablespoons) will be drawn for routine tests, including checking your
liver and kidneys and measuring the levels of sugar in your blood, and levels of fat in
your blood.

- You will asked about any side effects you have experienced.

- If the disease is in the pelvis, you will have a pelvic exam.

- If the doctor thinks it is needed, blood (about 1 teaspoon) will be drawn for hepatitis
testing.

- Your pills will be counted.

At Week 8, the following tests and procedures will be performed:

- You will have a physical exam, including a pelvic exam.

- You will have a CT and/or MRI scan of your chest, abdomen, and pelvis. Other areas will
be scanned if the doctor thinks it is needed.

- Any tumors will be measured. The doctor will either feel the tumor or a CT, x-ray,
and/or MRI will be used.

- If the disease is in your chest, you will have chest CT and/or MRI scan to check the
status of the disease.

- You will asked about any side effects you have experienced.

After the Week 8 Visit, you will have the following tests and procedures. (If the disease
has partially or completely responded to the study drugs, these tests will be done around
Week 12. If the disease is stable, these tests will be done around Week 16.)

- You will have a physical exam.

- You will have a CT and/or MRI scan of your chest, abdomen, and pelvis. Other areas will
be scanned if the doctor thinks it is needed.

- Any tumors will be measured. The doctor will either feel the tumor or a CT scan, x-ray,
and/or MRI will be used.

- If the disease is in your chest, you will have a chest CT and/or MRI scan to check the
status of the disease.

After the Week 12 or 16 visit, every 12 weeks, the following tests and procedures will be
performed:

- You will have a pelvic exam.

- You will have a CT and/or MRI scan of your chest, abdomen, and pelvis. Other areas will
be scanned if the doctor thinks it is needed.

- If the disease is in your chest, you will have chest CT and/or MRI scan to check the
status of the disease.

Length of Study:

You may continue receiving additional cycles of study treatment. You will be taken off study
if you experience intolerable side effects, the disease gets worse, the disease completely
responds, or the doctor thinks it is in your best interest.

End of Treatment Visi:t

Within 4 weeks after the last dose of study drugs, you will have an end-of-treatment visit.
At this visit, the following tests and procedures will be performed:

- You will have a physical exam, including measurement of your weight and vital signs.

- You will have a pelvic exam.

- Your performance status will be recorded.

- Blood (about 2 tablespoons) will be drawn for routine tests, including checking your
liver and kidneys and measuring the levels of sugar in your blood, and levels of fat in
your blood.

- You will have a CT and/or MRI scan of your chest, abdomen, and pelvis. Other areas will
be scanned if the doctor thinks it is needed.

- If the disease is in your chest, you will have chest CT and/or MRI scan to check the
status of the disease.

- Your pills will be counted and any unused study drug will be returned.

Long Term Follow-up:

After you are off study, you will be followed by your doctor on a regular basis. How often
these visits occur are up to you and your doctor. The following tests and procedures will be
performed:

- You will have a physical exam, including measurement of your weight and vital signs.

- You will have a pelvic exam.

- Your performance status will be recorded.

- You will be asked if you have experienced any intolerable side effects.

- You will have a CT and/or MRI scan of your chest, abdomen, and pelvis. Other areas will
be scanned if the doctor thinks it is needed.

- If the disease is in your chest, you will have chest CT and/or MRI scan to check the
status of the disease.

This is an investigational study. Everolimus is not FDA approved or commercially available.
At this time, everolimus is only being used in research. Letrozole is FDA approved and
commercially available for the treatment of breast cancer and ovarian cancer. The
combination of everolimus and letrozole in this study for the treatment of endometrial
cancer is also investigational. Up to 42 patients will take part in the multicenter study.
Up to 42 will be enrolled at MD Anderson.


Inclusion Criteria:



1. Patients must have signed an approved informed consent.

2. Histologically confirmed endometrial cancer (endometrioid, serous, or clear cell, or
mixed histology; any grade) which is considered progressive or recurrent.

3. Patients may have failed no more than two prior chemotherapeutic regimens for
recurrent or advanced disease (including adjuvant therapy). Chemotherapy administered
in conjunction with radiation as a radio-sensitizer is not counted as a prior
treatment for recurrent or advanced disease.

4. All patients must have measurable disease as defined by RECIST 1.1.

5. Patients must have at least one "target lesion" to be used to assess response on this
protocol as defined by RECIST. Tumors within a previously irradiated field will be
designated as "non-target" lesions, unless progression is documented or a biopsy is
obtained to confirm persistence at least 90 days following completion of radiation
therapy.

6. Patients must have a Zubrod performance status of 0, 1, or 2.

7. Patients must not be of child bearing potential. Patients are considered not of child
bearing potential if they are surgically sterile (they have undergone a hysterectomy,
bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal for
greater than 12 months. Patients in whom ovaries are present and were not previously
menopausal at the time of hysterectomy, should have a serum estradiol < 10 pg/mL to
confirm ovarian senescence.

8. Patients must have a pretreatment granulocyte count (i.e., segmented neutrophils +
bands) of >1,500/Fl, a hemoglobin level of >/=9gm/dL and a platelet count of
>100,000/Fl. Close contact with those who have received attenuated live vaccines
should be avoided during treatment with everolimus. Examples of live vaccines include
intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever,
varicella and TY21a typhoid vaccines.

9. Patients must have an adequate renal function of >50cc/min as documented by the
Cockcroft Gault creatinine clearance formula: Estimated GFR = (140 - age) x (weight
kg) divided by 72 x serum Creatinine (non-IDMS) x 0.85 (female)

10. Patients must have adequate hepatic function as documented by a serum bilirubin
tumor. Note: A detailed assessment of Hepatitis B/C medical history and risk factors
must be done at screening for all patients. HBV DNA and HCV RNA 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.

11. Alanine aminotransferase (SGPT) must be unless the liver is involved with tumor, in that case, the alanine aminotransferase
must be
12. Prior to beginning therapy, at least 4 weeks must have elapsed since prior
chemotherapy, surgery, radiation therapy, hormonal therapy or investigational
therapy. Patients receiving palliative radiation therapy are exempt from the 4 week
waiting period.

13. Baseline lipid levels (triglycerides, cholesterol) must be allowed to be on lipid lowering drugs.

14. Patients must be >/= 18 years of age.

Exclusion Criteria:

1. Patients with intact ovarian function.

2. Patients who have previously received RAD001 or another mTOR inhibitor or letrozole
or another aromatase inhibitor. Use of progestational or other hormonal agents are
permitted provided they have not been administered within the previous 4 weeks.

3. Patients who have uterine sarcomas or mixed malignant mullerian tumors.

4. Patients who have isolated recurrences (vaginal, pelvic, or paraaortic) that are
amenable to potentially curative treatment with radiation therapy or surgery.

5. Patients with any other severe concurrent disease, which would make the patient
inappropriate for entry into this study, including significant hepatic, renal, or
gastrointestinal diseases.

6. Patients currently receiving chemotherapy or radiotherapy or those in whom
anti-cancer treatment has occurred within the preceding 4 weeks.

7. Chronic treatment with systemic steroids or another immuno-suppressive agent.

8. Patients should not receive immunization with attenuated live vaccines within one
week of study entry or during study period.

9. Patients with a history of prior malignancy except for adequately treated basal cell
or squamous cell skin cancer, in situ cervical cancer, or other cancer for which the
patient has been disease-free for at least five years

10. Patients with active infection that requires systemic antibiotics.

11. Patients with a known history of cardiac disease; i.e., uncontrolled hypertension
(systolic B/P >/= 140 mm Hg and/or diastolic B/P >/= 90 mm Hg) or unstable angina.
Patients with a history of myocardial infarct within 6 months before enrollment, New
York Heart Association (NYHA) Class II or greater heart failure, or symptoms
suspicious for congestive heart failure are not eligible unless a left ventricular
ejection fraction in the past 6 months is documented to be 50% or greater. Patients
who have had a LVEF (performed for any reason) of less than 50% in the past 6 months
are ineligible.

12. Patients with a known history severely impaired lung function (patients who are
oxygen dependent).

13. Patients with a known hypersensitivity to RAD001 (everolimus) or other rapamycins
(sirolimus, temsirolimus) or to its excipients.

14. Patients who are pregnant or breast-feeding.

15. Presence of clinically apparent untreated central nervous system metastases.

16. Patients with carcinomatous meningitis.

17. Patients with deep venous or arterial thrombosis (including pulmonary embolism)
