Pre-surgical Androgen Deprivation Therapy With or Without Axitinib in Previously Untreated Prostate Cancer Patients With Known or Suspected LymphNode Metastasis
Study Drug:
Axitinib is designed to block the formation of new blood vessels, which are involved in the
growth and development of tumors.
Study Groups:
If you are found to be eligible to take part in this study, you will be randomly assigned
(as in the roll of the dice) to 1 of 2 groups:
- If you are in Group A, you will receive axitinib and hormonal therapy.
- If you are in Group B, you will receive hormonal therapy alone.
You will have a 2 out of 3 chance of being placed in Group A. You have a 1 out of 3 chance
of being placed in Group B.
Study Drug Administration:
All participants will receive hormonal therapy. The hormonal drug you receive will be
standard of care hormone therapy. The study doctor will decide what hormone therapy you will
receive and will explain when and how you should take the hormone therapy and any risks.
You will have 8 weeks of hormone therapy before you are assigned to a study group. After you
are assigned to a study group, you will receive up to 6 more months of hormone therapy.
If you are in Group A, you will also take 1 capsule of axitinib by mouth 2 times a day. You
will be asked to take your blood pressure 2 times a week and record it in a diary before
taking your axitinib dose. Note: If your blood pressure is above 150 systolic (the upper
number) OR above 100 diastolic (the lower number) or if you develop any symptoms related to
increased blood pressure please contact your study doctor immediately. You can take your
blood pressure at home or elsewhere, such as at the drug store or doctors office. Doses
should be taken about 12 hours apart and at about the same time each day, with food. If you
miss a dose, you may take it up to 3 hours late before the next scheduled dose; otherwise do
not make up the missed dose. Instead, skip the missed dose and take your next dose as
scheduled. If you vomit any time after taking a dose do not make it up, but instead take
your next dose as scheduled. You will be asked to keep a diary to help you keep track of
when you take each dose of the study drug. Record any missed or vomited doses in the diary.
Bring the diary with you to each visit.
Each cycle is 30 days. You should return all unused study drug and/or empty pill bottles at
the end of each cycle.
Study Visits:
At every visit, you will be asked about any side effects you have had and any drugs you may
be taking.
About 8 weeks after you begin hormonal therapy:
- Your medical history will be recorded.
- You will have a physical exam, including measurement of your weight and vital signs.
- Your performance status will be recorded.
- Blood (about 3-4 teaspoons) will be drawn for routine tests and to check your PSA. Your
blood will also be tested for levels of certain proteins.
- You will have an ultrasound-guided biopsy of the prostate with 10-12 samples collected.
You will be separately consented for this biopsy, which will describe the procedure
and its risks in more detail.
- Blood (about 2 tablespoons) will be drawn for routine tests. Your blood will also be
tested to check your thyroid function (Group A only).
- Urine will be collected for routine tests (Group A only).
- You will have an ECG (Group A only).
On Day 15 of Cycle 1 (Group A only):
- Your vital signs and weight will be measured.
- Blood (about 3-4 teaspoons) will be drawn for routine tests and to check your thyroid
function.
On Day 1 of Cycles 2, 3, and 5 (Group A only):
- Your medical history will be recorded.
- You will have a physical exam, including measurement of your weight and vital signs.
- Your performance status will be recorded.
- Blood (about 3-4 teaspoons) will be drawn for routine tests to check your PSA and
testosterone levels, and to check your thyroid function (Day 1 of Cycle 3 only).
- Urine will be collected for routine tests
About 3 months before surgery (Group B only):
- Your medical history will be recorded.
- You will have a physical exam, including measurement of your weight and vital signs.
- Your performance status will be recorded.
- Blood (about 2 teaspoons) will be drawn to check your PSA and testosterone levels.
About 2 weeks before surgery or if you go off study early:
- Your medical history will be recorded.
- You will have a physical exam, including measurement of your weight and vital signs.
- You will have a digital rectal exam.
- Your performance status will be recorded.
- Blood (about 3-4 teaspoons) will be drawn for routine tests and to check your PSA and
testosterone levels. Your blood will also be tested for levels of certain proteins.
- You will have a CT scan or MRI scan of the chest, abdomen, and pelvis to check the
status of the disease.
- You will have a bone scan to check the status of the disease.
- Blood (about 2 tablespoons) will be drawn for routine tests. Your blood will also be
tested to check your thyroid function (Group A only).
Length of Study:
You may receive the study drug(s) for about 8 months. You will be taken off study early if
the disease gets worse, if you have intolerable side effects, or if your study doctor thinks
it is in your best interest to stop.
Your participation on the study will be over once you have completed the follow-up visits
after surgery.
Surgery:
After 8 months of study treatment, you will have surgery to remove your prostate. You will
be asked to sign a separate consent form for this surgery, and the risks will be discussed
with you.
Long-Term Follow-Up:
At 1 month after your surgery:
- You will be asked about any drugs or treatments you may be receiving (including
over-the-counter drugs, herbal remedies, vitamins, and/or supplements).
- You will be asked about any side effects you have had.
- You will have a physical exam, including measurement of your weight and vital signs.
- Your performance status will be recorded.
- Blood (about 2 teaspoons) will be drawn for PSA and testosterone levels.
- If you are in Group A, blood (about 2 tablespoons) will be drawn for routine tests.
At 3 months after your surgery:
- Your medical history will be recorded.
- You will be asked about any disease-related symptoms and/or side effects you may have
had.
- You will have a physical exam, including measurement of your weight, height, and vital
signs.
- Your performance status will be recorded.
- Blood (about 3-4 teaspoons) will be drawn for routine tests and to check your PSA and
testosterone levels.
You will have follow-up visits every 3 months for the first year, every 4 months for the
second year, every 6 months in the third to fifth year, and 1 time a year after that unless
the disease worsens, you start taking hormone therapy, or you begin radiation treatments. At
these visits, blood (about 1 teaspoon) will be drawn to test your PSA level.
This is an investigational study. Axitinib is not FDA approved or commercially available.
Axitinib is currently being used for research purposes only.
Up to 54 patients will be enrolled in this study. All will be enrolled at MD Anderson.
