Bicalutamide With or Without Enzastaurin in Treating Patients With Prostate Cancer
Lead Sponsor:

Collaborating Sponsors:
National Cancer Institute (NCI)
Conditions:
Prostate Cancer
Eligibility:
MALE
18+ years
Phase:
PHASE2
Brief Summary
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as bicalutamide, may lessen the amount of androgens made by the body. Enzastaurin may stop the growth of t...
Detailed Description
OBJECTIVES: Primary * To compare the two regimens on the proportion of patients with undetectable prostate-specific antigen (PSA) level (\< 0.2 ng/mL) at 44 weeks. Secondary * To assess the propor...
Eligibility Criteria
Inclusion
- DISEASE CHARACTERISTICS:
- Histologically confirmed prostate cancer
- Hormone-sensitive disease, as evidenced by a serum total testosterone level \> 150 ng/dL
- No evidence of metastatic disease on physical exam, CT abdomen/pelvis (or MRI), chest x-ray or CT scan and bone scan within 6 weeks prior to randomization
- Underwent prior definitive surgery or radiotherapy
- Must have evidence of biochemical failure after primary therapy and subsequent progression as determined by 1 of the following:
- Prostate-specific antigen (PSA) ≥ 0.4 ng/mL (in case of radical prostatectomy)
- PSA rise ≥ 2 ng/mL above the nadir PSA (in case of radiotherapy)
- Baseline PSA must be at least 2 ng/mL and no greater than 50 ng/mL
- PSA doubling time (PSADT) \< 12 months
- PATIENT CHARACTERISTICS:
- ECOG performance status 0 - 1
- Granulocytes ≥ 1,500/mm\^3
- Platelet count ≥ 75,000/mm\^3
- Serum creatinine normal or creatinine clearance ≥ 60 mL/min
- Serum total bilirubin ≤ 1.5 times upper limit of normal (ULN)
- Alkaline phosphatase ≤ 2.5 times ULN
- SGOT and SGPT \< 2.5 times ULN
- PT/INR normal
- Fertile patients must use effective barrier contraception during and for at least 3 months after completion of study treatment
- No gastrointestinal (GI) tract disease resulting in: inability to take oral medication, malabsorption syndrome, a requirement for IV alimentation, prior surgical procedures affecting absorption, or uncontrolled inflammatory GI disease (e.g., Crohn's, ulcerative colitis)
- No history of allergic reactions attributed to compounds of similar chemical or biologic composition to enzastaurin hydrochloride or bicalutamide
- No uncontrolled intercurrent illness including, but not limited to, any of the following:
- Ongoing or active infection
- Symptomatic congestive heart failure
- Unstable angina pectoris
- Cardiac arrhythmia
- Psychiatric illness/social situations that would limit compliance with study requirements
- A history of other malignancy is permitted if the patient is predicted to be disease-free for 2 years
- PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- More than 4 weeks since prior salvage therapy with intent to cure (i.e., surgery, radiotherapy, or other local ablative procedures)
- More than 4 weeks since prior prophylactic radiotherapy to prevent gynecomastia
- More than 1 year since prior therapy modulating testosterone levels (such as luteinizing-hormone releasing-hormone agonists/antagonists and antiandrogens) unless in the neoadjuvant or adjuvant setting
- No 5 alpha reductase inhibitors, ketoconazole, megestrol acetate, systemic steroids, or herbal supplements during PSA value collection
- At least 14 days since prior enzyme-inducing anti-epileptic drugs (EIAEDs)
- Patients who must begin EIAED therapy while on study are allowed to remain
- No concurrent combination antiretroviral therapy for HIV-positive patients
- No concurrent anticoagulant therapy
- Low dosage acetyl salicylic acid ≤ 325 mg/day allowed
- No other concurrent investigational agents or anticancer therapy (i.e., chemotherapy, immunotherapy, radiotherapy, surgery for cancer, or experimental medications)
- No history of allergic reactions attributed to compounds of similar chemical or biologic composition to enzastaurin or bicalutamide
- Prior neoadjuvant and/or adjuvant therapy ≤ 4 weeks prior to randomization (i.e., hormones, chemotherapy, vaccines, or experimental agents) allowed if PSA rise and PSADT were documented after testosterone level was \> 150 ng/dL
