Study Description
Brief Summary
The purpose of this study is to compare the effects on prostate cancer using radiation therapy with or without chemotherapy.

Phase 2/Phase 3 |
Detailed Description
The recommended treatment for a high risk prostate cancer consists of a combination of radiation therapy and androgen suppression for 2-3 years. Recent studies have shown a survival advantage for chemotherapy for prostate cancer. Chemotherapy has already been successfully integrated in the treatment of other cancer types and is our belief that chemotherapy will prove to be beneficial for patients with high risk prostate cancer. However, a clinical study is necessary to compare the results good or bad of chemotherapy with radiation therapy.

Outcome Measures
Primary Outcome Measures
- Phase 2 - Assessment of Number of Freedom From Failure Events in the Chemotherapy Arm [No failures were reported at the time of study termination (22 months). This outcome was originally written to assess failure at 2 years. However, that end point was not reached.]
Measurement of Freedom from Failure i.e. the first occurence of clinical failure (local recurrence, regional recurrence, or distant metastasis), biochemical failure by the Phoenix definition (Prostate Specific Antigen [PSA] > = 2 ng/ml over the nadir PSA discounting bounces per the investigators discretion), or the start of salvage therapy including androgen deprivation. This study was terminated prior to the time frame of 2 years being reached. Therefore, this outcome was assessed at time of study closure (22 months).
- Phase 2 - Assessment of Number of Freedom From Failure Event Comparing Chemotherapy Arm to Standard Treatment Arm [at 5 years]
This endpoint will be examined if decision is made to not move forward with phase 3 study. This study was terminated prior to a decision being made about moving on to a phase 3 study. Therefore, this outcome was not assessed.
- Phase 2 - Cumulative Number of Incidences of Grade 3 or Higher Adverse Events. [2 years]
Assessment will be performed using CTCAE v4 criteria. This study was terminated prior to the time frame of 2 years being reached. Therefore, this outcome was assessed at time of study closure (22 months).
- Phase 3 - Assessment of the Number of Freedom From Failure (FFF) Events Comparing the Chemotherapy Arm to the Standard Treatment Arm. [at 5 years]
The events for FFF will be the first occurence of clinical failure (local recurrence, regional recurrence, or distant metastasis), biochemical failure by the Phoenix definition (PSA > = ng/ml over the nadir PSA discounting bounces per the investigators discretion), or the start of salvage androgen deprivation. This study was terminated prior to a decision being made about moving on to a phase 3 study. Therefore, this outcome was not assessed.
Secondary Outcome Measures
- Assessment of Number of Grade 2 or Higher Genitourinary (GU) and Gastrointestinal (GI) Adverse Events [at 6 months]
Assessment will be performed using CTCAE v 4 criteria.
- Assessment of Number of GI and GU Adverse Events [at 3 years]
Descriptive measurements of frequency will be compiled. This study was terminated prior to the time frame of 3 years being reached. Therefore, this outcome was not assessed. Data were collected on toxicities up until study closure at 22 months. However, this timepoint was not indicated as a secondary objective in the protocol. Therefore, data was not analyzed at time of study closure.
- Assessment of Total Number of Local/Distant Failures [at time of study closure (22 months)]
The total number of local/distant failures will be assessed.
- Assessment of Impotence by Summation of Relative Scores for Sexual Function From the EPIC Quality of Life Instrument. [Up to 10 years]
unable to assess due to lack of data
- Assessment of Total Number of Salvage Androgen Deprivation Use With Comparison of Arms. [At study closure (22 months)]
The total number of subjects with salvage androgen deprivation use will be assessed.
- Assessment of Total Number of Survival Events With Comparison of Group Arms [at study closure (22 months)]
The number of deaths in both arms will be assessed.
- Assessment of Total Number of Biochemical Failure Events [at study closure (22 months)]
The number of biochemical failure events will be assessed on both arms.
- Assessment of Quality of Life - Summation of Relative Scores From the EPIC Instrument. [Up to 10 years]
unable to assess due to lack of data
