Clinical Trial Summary

This randomized phase II/III trial studies docetaxel, antiandrogen therapy, and radiation therapy to see how well it works compared with antiandrogen therapy and radiation therapy alone in treating patients with prostate cancer that has been removed by surgery. Androgen can cause the growth of prostate cells. Antihormone therapy may lessen the amount of androgen made by the body. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving antiandrogen therapy and radiation therapy with or without docetaxel after surgery may kill any remaining tumor cells.

Description:

PRIMARY OBJECTIVES: I. To assess the benefit of docetaxel as measured by improvement in freedom from progression (phase II) and subsequently metastasis free survival (phase III) when given in combination with radiation and androgen deprivation in treatment of high risk prostate cancer post-radical prostatectomy. SECONDARY OBJECTIVES: I. To assess overall survival. II. To assess local time to progression. III. To assess undetectable prostate-specific antigen (PSA) with a non-castrate testosterone at 2.5 years post treatment. IV. To assess the utility of genomic profiling in making adjuvant therapy decisions post-prostatectomy. V. To assess toxicity of docetaxel in the post-operative setting when combined with radiation and androgen deprivation therapy. VI. To assess treatment response by genomically defined sub-groups of prostate cancer patients. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive androgen deprivation therapy comprising leuprolide acetate, goserelin acetate, bicalutamide, flutamide, or nilutamide for 6 months. Beginning 8 weeks after the start of androgen deprivation therapy, patients receive external beam radiation therapy (EBRT) for 7.5 weeks. ARM II: Patients receive androgen deprivation therapy and EBRT as in Arm I. Within 4-6 weeks after completion of radiation therapy, patients receive docetaxel intravenously (IV) on day 1 of every 21 days for 6 courses in the absence of disease progression or unexpected toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years, and then yearly.

Eligibility

Inclusion Criteria:

• Baseline testosterone level obtained post prostatectomy prior to the start of androgen deprivation therapy and prior to step 1 registration
• Pathologically (histologically) proven diagnosis of adenocarcinoma of the prostate as confirmed at time of prostatectomy; prostatectomy must have been performed =< 365 days (1 year) prior to step 1 registration
• Primary treatment with radical prostatectomy
• Any type of radical prostatectomy is permitted, including retropubic, perineal, laparoscopic or robotically assisted
• Prior ablative treatment for treatment of benign prostatic hypertrophy or focal high-intensity focused ultrasound therapy (HIFU) prior to prostatectomy is allowed

• No distant metastases, based upon the following minimum diagnostic workup:
• A computed tomography (CT) scan of the abdomen and/or pelvis (with contrast if renal function is acceptable; a CT without contrast is permitted if the patient is not a candidate for contrast) or magnetic resonance imaging (MRI) of the pelvis within 120 days prior to step 1 registration; lymph nodes will be non-metastatic unless they measure more than 1.5 cm short axis;
• Bone scan within 120 days prior to step 1 registration (a sodium fluoride [NaF] positron emission tomography/computed tomography [PET/CT] is an acceptable substitute); if the bone scan is suspicious, a plain x-ray, CT scan, NaF PET/CT and/or MRI must be obtained to rule out metastasis
• Eastern Cooperative Oncology Group (ECOG) performance status of =< 1 within 90 days prior to step 1 registration
• Platelets >= 1 X 10^6 cells/mm^3 (100,000) based upon complete blood count (CBC)

Exclusion Criteria:

• Definitive clinical or radiologic evidence of metastatic disease

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Freedom from progression (FFP) (Phase II)	Will be determined with a one-sided stratified log-rank test when 89 FFP events have been observed. Both unadjusted and adjusted hazard ratios and the respective 95% confidence interval will be computed. Events for FFP will be the first occurrence of biochemical failure by PSA >= 0.4 ng/ml over the nadir PSA confirmed by a second PSA higher than the first by any amount, recurrence (local, regional or distant), institution of secondary androgen deprivation therapy and death from any cause.	From time of randomization to first event, assessed up to 43 months
Primary	Metastasis free survival (MFS) (Phase III)	Will be measured with a one-sided stratified log-rank test when 282 MFS events have been observed. Both unadjusted and adjusted hazard ratios and the respective 95% confidence interval will be computed.	From time of randomization to first occurrence of distant metastasis or death from any cause, assessed up to 9.5 years
Secondary	Overall survival	Will be analyzed using log-rank methodology and Cox proportional models. Tests for violations of proportionality will performed for the survival models. Both unadjusted and adjusted hazard ratios and the respective 95% confidence interval will be computed.	Time to death from any cause assessed up to 9.5 years
Secondary	Time to local progression	Data will be summarized by cumulative incidence curves. Fine and Gray models will be used to adjust inference for competing risks. Both unadjusted and adjusted hazard ratios and the respective 95% confidence intervals will be computed.	Baseline to local or regional recurrence ignoring biochemical failure and distant recurrence and censoring for death, assessed up to 2.5 years
Secondary	Proportions of patients with Grade 3 through Grade 5 adverse events that are either related to study drug or not graded according to NCI CTCAE version 3.0	Frequencies, proportions and severity of acute adverse events by treatment arm will be presented. Specifically, Grade 3 - 5 adverse events will be tallied. Adverse events related to study drug will also be tallied.	Up to 30 days post radiation therapy
Secondary	Proportion of undetectable PSA with a non-castrate testosterone	Both unadjusted and adjusted odds ratios and the respective 95% confidence interval will be computed.	At 2.5 years post treatment
