Trial Information

A Phase I Trial of Sirolimus and Cetuximab in Patients With Advanced Malignancies


The Study Drugs:

Cetuximab is designed to prevent or slow down the growth of cancer cells by blocking protein
on the surface of the cancer cell, called the epidermal growth factor receptor (EGFR).

Sirolimus is designed to block a protein called mTOR inside the cancer cell. This may
interfere with the growth or spread of cancer cells or possibly kill the cancer cells.

Study Drug Groups:

If you are found to be eligible to take part in this study, you will be assigned to a dose
level of cetuximab and sirolimus based on when you joined this study. Up to 9 dose levels
of cetuximab and sirolimus will be tested. Three (3) to 9 participants will be enrolled at
each dose level. The first group of participants will receive the lowest dose level. Each
new group will receive a higher dose than the group before it, if no intolerable side
effects were seen. This will continue until the highest tolerable dose of the combination
of cetuximab and sirolimus is found.

Once the highest tolerated dose of the combination of cetuximab and sirolimus is found, 2
groups of additional participants (Group 1 and Group 2, each of 14 participants) will be
enrolled and receive the study drugs at that dose level. Another 14 participants with the
non-small lung and head and neck cancer will receive the study drug at that dose level, as
well.

Study Drug Administration:

Each study "cycle" is 28 days.

Everyday, you will take sirolimus by mouth 1 time a day. You should take it at about the
same time each day with food and a cup of water.

On Days 1, 8, 15, and 22 of each cycle, you will receive cetuximab by vein over 2 hours. If
the first dose is well tolerated, you will receive the next dose over 1 hour.

Study Visits:

At every study visit, you will be asked about any current health conditions you have, drugs
you are taking, and if you have experienced any side effects.

Between Days 8 and 15 of Cycle 1, the following tests and procedures will be performed:

-If you are enrolled in a Group 2 of the highest drug combination dose, you will have a
tumor biopsy and your blood (about 1-3 tablespoons) will be drawn for PD testing.

About Days 8 and 22 of Cycle 1, the following tests and procedures will be performed:

- You will have a physical exam.

- Blood (about 2 teaspoons) will be drawn for routine tests.

About Day 15 of Cycle 1, blood (about 2 teaspoons) will be drawn for routine tests.

About Day 22 of Cycles 2 and then every 1-2 cycles, the following tests and procedures will
be performed:

- You will have a physical exam.

- Blood (about 2 teaspoons) will be drawn for routine tests.

Every 4 weeks, you will have a blood (about 1 teaspoon) drawn or urine collected for
pregnancy test if you are able to become pregnant.

Every 8 weeks, you will have an x-ray, CT scan, MRI, and/or PET/CT to check the status of
the disease. The study doctor thinks it is needed, they will be performed more often.

Length of Study:

You may stay on study for as long as you are benefitting. You will be taken off study if you
experience intolerable side effects, the study doctor thinks it is in your best interest, or
the cancer gets worse.

End-of-Study Visit:

About 28 days after the last dose of study drugs, you will have an end-of-study visit. At
this visit, the following tests or procedures may be performed:

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

- Your performance status will be recorded.

- Blood (about 2 teaspoons) will be drawn for routine tests.

- If the doctor thinks it is needed, you will have an x-ray, CT, MRI, and/or PET/CT to
check the status of the disease.

This is an investigational study. Sirolimus is FDA approved and commercially available as
an anti-rejection drug for kidney transplant recipients. Cetuximab is FDA approved and
commercially available for the treatment of colorectal and head/neck cancers. The
combination of these drugs is investigational.

Up to 137 patients will take part in this study. All will be enrolled at MD Anderson.


Inclusion Criteria:



1. Patients with advanced or metastatic cancer that is refractory to standard therapy,
relapsed after standard therapy, or who have no standard therapy available that
improves survival by at least three months.

2. Patients must be >/= 3 weeks beyond treatment with a cytotoxic chemotherapy regimen,
or therapeutic radiation, or major surgery. Patients may have received palliative
localized radiation immediately before or during treatment providing radiation is not
delivered to the only site of disease being treated under this protocol. For
biologic/targeted agents patients must be >/= 5 half-lives or >/= 3 weeks form the
last dose (whichever comes first).

3. ECOG performance status
4. Patients must have normal organ and marrow function defined as: absolute neutrophil
count >/= 1,000/mL; platelets >/=50,000/mL; creatinine bilirubin triglycerides
5. Women of child-bearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control; abstinence) prior to study entry, for
the duration of study participation, and for 30 days after the last dose.

6. Patients with colorectal cancer with kRAS mutations (mutational status must be
available prior to entering the study)

7. Patients must be able to understand and be willing to sign a written informed consent
document.

Exclusion Criteria:

1. Uncontrolled intercurrent illness including, but not limited to, uncontrolled
infection, uncontrolled asthma, need for hemodialysis, need for ventilatory support.

2. Pregnant or lactating women.

3. History of hypersensitivity to cetuximab, murine products, or any component of the
formulation.

4. History of hypersensitivity to sirolimus.

5. History of hypersensitivity to any component of the formulation.

6. Patients with colorectal cancer with kRAS mutations. (mutational status must be
available prior to entering the study)

7. Patients unwilling or unable to sign informed consent document.
