Phase III Trial of Dose Escalated Radiation Therapy and Standard Androgen Deprivation Therapy (ADT) With a GNRH Agonist vs. Dose Escalated Radiation Therapy and Enhanced ADT With a GNRH Agonist and TA

Trial Conditions
  • Prostate Cancer
What is the purpose of this trial?

RATIONALE: Androgens can cause the growth of prostate cancer cells. Drugs, such as steroid 17alpha-monooxygenase TAK-700, when used with other hormone therapy, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for prostate cancer when combined with hormone therapy. Studying quality-of-life in patients having cancer treatment may help identify the intermediate- and long-term effects of treatment on patients with prostate cancer. PURPOSE: This randomized phase III trial is studying the use of hormone therapy, including TAK-700, together with radiation therapy in treating patients with prostate cancer.

- Histologically confirmed diagnosis of adenocarcinoma of the prostate within 180 days
prior to registration at high risk for recurrence as determined by one of the
following combinations (risk group):

- Gleason Score (GS) ≥ 9, PSA ≤ 150 ng/mL, any T stage

- GS ≥ 8, PSA < 20 ng/mL, T stage ≥ T2

- GS ≥ 8, PSA ≥ 20-150 ng/mL, any T stage

- GS ≥ 7, PSA ≥ 20-150 ng/mL, any T stage

- Baseline serum PSA value performed with an FDA-approved assay (e.g., Abbott,
Hybritech), obtained prior to any luteinizing hormone-releasing hormone (LHRH)
agonist or antiandrogen therapy, within 180 days of randomization

- Androgen deprivation therapy (ADT), such as LHRH agonists (e.g., goserelin,
leuprolide), anti-androgens (e.g., flutamide, bicalutamide), estrogens (e.g.,
diethyl- stilbestrol [DES]), or surgical castration (orchiectomy), may have been
started prior to registration, provided that registration is within 50 days of
beginning ADT; please note: if the patient has started ADT he will not be eligible to
participate in the quality of life component of this study

- Clinically negative lymph nodes as established by imaging (abdominal and/or pelvic CT
or abdominal and/or pelvic MRI), nodal sampling, or dissection within 90 days prior
to registration

the nodes are < 2.0 cm

- No distant metastases (M0) on bone scan within 90 days prior to registration

prostate volume < 60 cc, American Urological Association (AUA) score ≤ 15 within 60
days of registration, and no history of prior transurethral resection of the prostate

(EBRT) only

8.0 g/dL is acceptable)

- Serum creatinine < 2.0 mg/dL

- Creatinine clearance > 40 mL/minute

- Bilirubin < 1.5 x upper limit of normal (ULN)

- Alanine aminotranserase (ALT) or aspartate aminotransferase (AST) < 2.5 x ULN

- No PSA > 150 ng/mL

- Screening calculated ejection fraction ≥ ULN by multiple-gated acquisition (MUGA)
scan or by echocardiogram

- Androgen deprivation therapy (ADT), such as LHRH agonists (e.g., goserelin,
leuprolide), anti-androgens (e.g., flutamide, bicalutamide), estrogens (e.g., DES),
or surgical castration (orchiectomy) may have been started prior to registration,
provided that registration is within 50 days of beginning ADT.

- Patients, even if surgically sterilized (i.e., status post vasectomy), must agree to
practice effective barrier contraception during the entire study treatment period and
for 4 months (120 days) after the last dose of study drug

- No prior invasive malignancy (except non-melanoma skin cancer) unless disease-free or
not requiring systemic therapy for a minimum of 3 years

- No known hypersensitivity to TAK-700 or related compounds

- No history of adrenal insufficiency

- No history of myocardial infarction, unstable symptomatic ischemic heart disease,
ongoing arrhythmias of grade > 2 (NCI CTCAE, version 4.02) thromboembolic events
(e.g., deep vein thrombosis, pulmonary embolism, or symptomatic cerebrovascular
events), or any other cardiac condition (e.g., pericardial effusion restrictive
cardiomyopathy) within 6 months prior to registration

- Chronic stable atrial fibrillation on stable anticoagulant therapy is allowed

- No New York Heart Association Class III or IV heart failure

- No ECG abnormalities of Q-wave infarction, unless identified 6 or more months prior
to screening, or corrected QT (QTc) interval > 460 msec

- No prior allergic reaction to the drugs involved in this protocol

- No Cushing syndrome

- No severe chronic renal disease or chronic liver disease

- No uncontrolled hypertension despite appropriate medical therapy within 21 days prior
to registration (blood pressure of greater than 150 mm Hg systolic and 90 mm Hg
diastolic at 2 separate measurements no more than 60 minutes apart during screening

- No serious infection within 14 days prior to registration

- No uncontrolled nausea, vomiting, or diarrhea (CTCAE grade ≥ 3) despite appropriate
medical therapy at the time of registration

- No known gastrointestinal (GI) disease or GI procedure that could interfere with the
oral absorption or tolerance of TAK-700, including difficulty swallowing tablets
