A Phase II, Prospective, Open Label Study to Determine the Safety and Efficacy of Pomalidomide (CC-4047) in Subjects With Primary, Post Polycythemia Vera, or Post Essential Thrombocythemia Myelofibrosis (PMF; Post-PV MF, or Post-ET MF)
The Study Drug:
CC-4047 is a drug that may also affect the growth of blood vessels that support tumor
growth. If these blood vessels stop growing, it may stop cancer cell growth.
Prednisone is a corticosteroid that is similar to a natural hormone made by your body.
Prednisone is often given in combination with other chemotherapy to treat cancer.
Study Drug Administration:
On Days 1- 28 of every 28-day study "cycle," you will take CC-4047 capsule(s) by mouth. You
should take the capsule(s), about the same time every day. The capsule(s) should not be
opened, broken, or chewed.
You will receive prednisone by mouth during the first 3 cycles of therapy. You will take it
1 time a day during Cycle 1. During Cycle 2, you will take a smaller dose 1 time a day.
During Cycle 3, you will take the same dose as in Cycle 2, but only 1 time every other day.
On Days 1-28, you will also take low-dose aspirin. This should be taken at the same time as
CC-4047. Aspirin is take to help prevent blood clots, which may occur from taking CC-4047.
If you are unable to take aspirin, your study doctor will have you take another drug.
You will be given a study "diary". In this diary, you will record when you take each dose
of the study drug. You will return any unused study drug and empty bottles at each visit.
Study Visits:
On Day 1 of Cycles 1 and 2, the following tests and procedures will be performed:
- You will have a physical exam, including measurements of your vital signs (blood
pressure, temperature, and heart rate) and weight.
- You will be asked about any drugs you are taking and about recent blood transfusions
you may have had.
- You will have a performance status evaluation.
- Blood (about 1 tablespoon) will be drawn for routine tests.
On Days 1, 8, 15, and 22 of Cycles 1 and 2, blood (about 4 teaspoons) will be drawn for
routine tests.
On Day 28 of each cycle, the following tests and procedures will be performed:
- You will be asked about any drugs you are taking and about recent blood transfusions
you may have had.
- You will be asked about any birth control methods you are using.
- You will have a physical exam, including measurement of your vital signs and weight.
- Measurements of your spleen and/or liver will be taken.
- You will have a performance status evaluation.
- Blood (about 4 tablespoons) will be drawn for routine tests.
- You will be asked about any new side effects or medical conditions you may have
experienced.
- You will complete a questionnaire about your quality-of-life as well as an assessment
of possible pain in your spleen. (Cycles 1 and 2 only)
On Day 28 of every third cycle (Cycle 3, 6, 9, and so on), the following tests and
procedures will be performed:
- Blood (about 4 teaspoons) will be drawn to test you thyroid function.
- You will have an ECG.
- Response of disease to therapy will be assessed. Bone marrow biopsy and aspirate will
be done to confirm a complete response if your doctor thinks it is needed.
Pregnancy Testing:
Women who are able to have children will have a pregnancy test every week during Cycle 1,
and then every 28 days after that if your menstrual cycle is regular (If your menstrual
cycle is not regular, you will have a blood pregnancy test every 2 weeks). These pregnancy
tests will be part of a routine blood draw.
Length of Study:
You will remain on study treatment as long as the therapy is beneficial to you. You will be
taken off study early if the disease gets worse or intolerable side effects occur.
End-of-Treatment Visit:
Once you are off study, you will have an end-of-study visit. At this visit, the following
tests and procedures will be performed:
- You will have a physical exam, including measurements of your vital signs and
measurements of your spleen and/or liver.
- You will have an ECG.
- You will be asked about any drugs you are taking and about any blood transfusions you
may have had.
- Blood (about 4 tablespoons) and urine will be collected for routine tests and thyroid
function tests. This routine blood draw will include a pregnancy test for women who
are able to have children.
- You will be asked about any side effects you may have experienced.
Follow-Up Visit:
Women who are able to have children will have a blood (about 1 tablespoon) pregnancy test 28
days after the last dose of study drug. If your periods are irregular you will have 2 blood
(about 1 tablespoon each time) pregnancy tests, one 14 days after the last dose of study
drug and another 28 days after the last dose of study drug. Response of disease to therapy
will be assessed at follow-up 28 days after last dose of study drug.
This is an investigational study. CC-4047 (pomalidomide) is FDA approved and commercially
available for the treatment of certain types of MM. Its use in this study is
investigational.
Prednisone is FDA approved and commercially available.
Up to 70 patients will take part in this study. All will be enrolled at M. D. Anderson.
