The Effects of Thalidomide on Symptom Clusters

Thalidomide is designed to change the immune system. It may also interfere with the
development of tiny blood vessels that help support tumor growth.

Before you can start treatment on this study, you will have "screening tests." These tests
will help the doctor decide if you are eligible to take part in this study. You will be
asked about your cancer diagnosis, the drugs you are taking, and the symptoms you are having
(for example, pain, fatigue, anxiety, depression, poor appetite, and sleep problems). Blood
(about 2 tablespoons) will be drawn to measure protein levels in your blood.

Women who are able to have children must have a negative blood (about 1 tablespoon)
pregnancy test 24 hours before beginning to receive thalidomide.

If you are found to be eligible to take part in this study, you will be randomly assigned
(as in toss of a coin) to one of 2 groups. You will have an equal chance of being placed in
either of the 2 groups. You, the medical staff, and researchers will not know which group
you have been assigned to.

Participants in Group 1, who are not on chemotherapy, will take 2 thalidomide capsules, by
mouth, once a day for 14 days. Participants in Group 1, who are on chemotherapy, will take
1 thalidomide capsule, by mouth, once a day for 7 days, and then 2 thalidomide capsules, by
mouth, once a day for 7 days.

Participants in Group 2, who are not on chemotherapy, will take 2 placebo capsules, by
mouth, once a day for 7 days. Participants in Group 2, who are on chemotherapy, will take 1
placebo capsule, by mouth, once a day for 7 days, and then 2 placebo capsules, by mouth,
once a day for 7 days. A placebo is a substance that looks like the study drug but has no
active ingredients.

You will complete 7 questionnaires, which will take about 30-60 minutes to complete. You
will also have blood drawn (about 2 tablespoons) to measure protein levels in your blood.
You will also have your body weight measured and be asked about your normal food intake.
Your body composition will be measured using measurements that include body weight and
height, skin fold thickness using Lange calipers, and bioelectrical impedance using the
Tanita body composition monitoring scale. This is a non-invasive method to measure total
body water, total body fat, and total body lean mass. The Tanita scale is similar to a
typical weight scale, although unlike a weight scale, the Tanita scale measures body
composition. Researchers will measure how much energy your body uses while at rest.

Every week, women who are able to have children must have a negative blood (about 1
tablespoon) pregnancy test.

On Day 8 [± 3 days], you will complete 3 questionnaires. The 3 questionnaires include
evaluation of your symptoms, fatigue level, and overall sense of well-being and should take
about 30 minutes to complete.

On Day 15 [± 3 days] you will have a study visit. You will be asked questions about any
side effects you may have experienced. You will be asked about any symptoms of pain,
fatigue, nausea, depression, poor appetite, and/or sleep problems. You will be asked to
complete 7 questionnaires which will take about 30-60 minutes to complete. You will also
have your body weight measured and be asked about your normal food intake. Your body
composition will be measured and researchers will measure how much energy your body uses
while at rest. Blood (about 2 tablespoons) will be drawn to measure protein levels in your
blood. All patients will be given the option to receive thalidomide until Day 30 [± 3
days].

If you decide not to take thalidomide on Days 15-30, you will be considered off-study. If
you decide to take thalidomide on Days 15-30, you will remain on study until Day 30. On Day
30 [± 3 days], you will have end-of-study tests.

On Day 30 [± 3 days], you will have an end-of-study visit. You will be asked questions
about any side effects you may have experienced. You will be asked about any symptoms of
pain, fatigue, anxiety, depression, poor appetite, and/or sleep problems.

Blood (about 2 tablespoons) will be drawn to measure protein levels in your blood. You will
be asked to complete 7 questionnaires which will take about 30-60 minutes to complete. You
will also have your body weight measured and be asked about your normal food intake. Your
body composition will be measured and researchers will measure how much energy your body
uses while at rest.

If you develop intolerable side effects, you will be taken off study. Otherwise, you will
be considered off-study on either Day 15 [± 3 days] or Day 30 [± 3 days]. Blood (about 1
tablespoon) will be drawn 2 weeks after thalidomide has been stopped to check for additional
side effects.

You and your doctor will have the option to continue your taking thalidomide off-study. You
will participate in the S.T.E.P.S.® (System for Thalidomide Education and Prescribing
Safety) program. This will include an additional consent, education about preventing
pregnancy while taking thalidomide, and completing surveys about following the rules of this
program.

This is an investigational study. Thalidomide is FDA-approved and commercially available.
Its use in this study, for this purpose, is investigational. Up to 62 patients will take
part in this study. All will be enrolled at M. D. Anderson.
