Lenalidomide in Combination With Bevacizumab, Sorafenib, Temsirolimus, or 5-Fluorouracil, Leucovorin, Oxaliplatin (FOLFOX)

The Study Drugs:

Lenalidomide is designed to change the body's immune system. It may also interfere with the
development of tiny blood vessels that help support tumor growth. This may decrease or
prevent the growth of cancer cells.

Bevacizumab is designed to block the growth of blood vessels that supply the nutrients
needed for tumor growth. This may prevent or slow down the growth of cancer cells.
Bevacizumab is no longer FDA approved to treat breast cancer.

Sorafenib is designed to block the function of important proteins in cancer cells. These
proteins, when active, are in part responsible for the abnormal growth and behavior of
cancer cells.

Temsirolimus is designed to block the growth of cancer cells, which may cause cancer cells
to die.

FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) is a drug combination designed to kill
rapidly dividing cells by stopping DNA (the genetic material of cells) from duplicating.
Because of a pharmacy shortage of IV leucovorin, patients will continue treatment without
leucovorin until it becomes available.

Study Groups (Arms):

If you are found to be eligible to take part in this study, you will be assigned to 1 of 4
study arms. Each study arm will receive lenalidomide in combination with 1 of the 4
drugs/drug combinations described in the "Study Drugs" section above. The arm you are
assigned to will depend on what arms are still open and what your doctor thinks is
appropriate for you. Your doctor will consider the type of disease you have, other drugs
you have received for the disease, and any side effects you may have seen with other drugs
when deciding which arm you should be assigned to:

- If you are in Arm 1, you will receive lenalidomide and bevacizumab.

- If you are in Arm 2, you will receive lenalidomide and sorafenib.

- If you are in Arm 3, you will receive lenalidomide and temsirolimus.

- If you are in Arm 4, you will receive lenalidomide and FOLFOX.

Up to 4 dose levels of the drug combination will be tested for each arm. Up to 6
participants will be enrolled at each dose level in each arm. For each arm, 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 for the drug combination is found for each arm. After the
highest tolerable dose of the drug combination is found, an additional 20 patients will be
able to receive this combination dose in each arm.

Study Drug Administration:

If you are in Arm 1, 2, or 3, each study "cycle" will be 28 days. If you are in Arm 4, each
study cycle will be 21 days.

If you are in Arms 1, 2, or 3, you will take lenalidomide by mouth 1 time each day during
Days 1-21 of each study cycle. If you are in Arm 4, you will take lenalidomide by mouth 1
time each day during Days 1-14 of each study cycle. Swallow lenalidomide capsules whole
with 1 cup (about 8 ounces) of water. Do not break, chew, or open the capsules.

If you miss a dose of lenalidomide, take is as soon as you remember on the same day. If you
miss taking your dose for the entire day, take your regular dose the next scheduled day (do
NOT take double your regular dose to make up for the missed dose). If you take more than
the prescribed dose of lenalidomide, you should seek emergency medical care if needed and
contact the study staff right away. Women who are able to become pregnant that might be
caring for you should not touch the lenalidomide capsules or bottles unless they are wearing
gloves. Any unused Revlimid® (lenalidomide) should be returned as instructed through the
RevAssist® program.

Arm 1:

You will receive bevacizumab by vein on Days 1 and 15 of each cycle. The first time you
receive bevacizumab, it will be given over 90 minutes. If you tolerate it well, the rest of
the doses will be given over 30-60 minutes.

Arm 2:

You will take sorafenib by mouth 1 time each day of every cycle (Days 1-28). You should
take it with a cup (8 ounces) of water, after taking lenalidomide. You should not eat or
drink anything other than water for at least 1 hour before or after taking sorafenib.

Arm 3:

You will receive temsirolimus by vein over 30-60 minutes on Days 1, 8, 15, and 22 of each
cycle.

Arm 4:

You will receive oxaliplatin and leucovorin by vein over 2 hours on Day 1 of each cycle.
You will also receive 5-FU by vein over 22 hours at home on Days 1-2. The drug will be
given through a pump that you carry with you.

Study Visits:

At all study visits, you will be asked about any side effects you may be having and about
any other drugs you may be receiving.

On Day 1 of Cycle 1, the following tests and procedures will be performed if they were not
performed within 7 days before Day 1 of Cycle 1:

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

- Your performance status will be recorded.

- Blood (about 1 tablespoon) will be drawn for routine tests.

On Day 15 of Cycle 1, blood (about 1 tablespoon ) will be drawn for routine tests.

On Day 1 of every even numbered cycle (Cycles 2, 4, 6, and so on):

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

- Your performance status will be recorded.

- Blood (about 1 tablespoon) will be drawn for routine tests.

At the end of every even numbered cycle (Day 28 for Arms 1, 2, and 3; Day 21 for Arm 4):

- You will have a CT scan, MRI scan, PET scan, or a PET/CT scan to check the status of
the disease. If the study doctor thinks it is in your best interest, other types of
scans that have not been listed here may also be performed. The study doctor will
explain these other types of scans to you in more detail, and you may be asked to sign
a separate consent form that describes the scans and their risks in more detail.

- If your study doctor thinks it is needed, you will have either a CT or MRI scan of the
brain to check the status of the disease.

- Blood (about 1 tablespoon) will be drawn for tumor markers.

On Day 1 of every odd numbered cycle (Cycles 3, 5, 7, and so on):

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

- Your performance status will be recorded.

- Blood (about 1 tablespoon) will be drawn for routine tests.

Pregnancy Testing:

If you are a woman who is able to become pregnant, you will have blood (about 1 teaspoon) or
urine pregnancy tests on Day 1 of every cycle, 1 time each week during the first cycle, when
you stop taking the study drugs, and 30 days after you stop taking the study drugs.

Length of Study:

You may continue taking the study drugs for as long as the doctor thinks it is in your best
interest. You will no longer be able to take the study drugs if the disease gets worse or
intolerable side effects occur.

Follow-Up Visit:

Thirty (30) days after you stop taking the study drugs for any reason, the following tests
and procedures will be performed:

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

- Your performance status will be recorded.

- Blood (about 2 tablespoons) will be drawn for routine tests and tumor marker testing.

- You will have an ECG.

- You will have a CT scan, MRI scan, PET scan, or PET/CT scan to check the status of the
disease. If the study doctor thinks it is in your best interest, other types of scans
that have not been listed here may also be performed. The study doctor will explain
these other types of scans to you in more detail, and you may be asked to sign a
separate consent form that describes the scans and their risks in more detail.

- If your study doctor thinks it is needed, you will have either a CT or MRI scan of the
brain to check the status of the disease.

This is an investigational study. All of the study drugs are FDA-approved and commercially
available for use in various types of cancer:

- Lenalidomide: multiple myeloma and myelodysplastic syndrome

- Bevacizumab: colorectal and lung cancers
