Stage IV Prostate Adenocarcinoma AJCC v7
Conditions
Brief summary
This is a phase 2.5 international, multi-institution, randomized clinical trial to evaluate the potential therapeutic effect of CRP combined with the BST in men with mPCa prospectively. Such hybrid design permits the inclusion of the patients who have accrued to the phase 2 investigation to phase 3 trial, thereby decreasing the number of patients needed overall (5-7). In the initial phase 2 study, we plan to accrue 190 patients.
Detailed description
PRIMARY OBJECTIVES: I. To assess the clinical benefit of combining radical surgery - cytoreductive radical prostatectomy (CRP) - with the best systemic therapy (BST) - to be determined by the treating physician in men with newly diagnosed clinical mPCa. SECONDARY OBJECTIVES: I. To determine the impact of CRP+BST on time to biochemical progression, cancer-specific survival, overall survival, complication rates, and quality of life (QOL) in patients with mPCa. II. To determine the transcription levels of bone morphogenetic protein -6 (BMP-6) and transforming growth factor-beta (TGF-?). OUTLINE: Participants are randomized to 1 of 2 arms. ARM I (Control Group): BST - to be determined by the treating physician (ADT +/- docetaxel at the discretion of the treating physician). ARM II: CRP + BST
Interventions
To demonstrate at least 30% improvement in FFS at 2 years after randomization with the power of 90% and error of 5% on a one-sided exponential MLE test.

Exclusion criteria
* Refuses to give informed consent * Deemed to have unresectable disease by surgeon * Received ADT for more than 6 months prior to consent * Life expectancy of less than 6 months prior to consent * Active spinal cord compression * Deep vein thrombosis (DVT) / pulmonary embolism (PE) in the past 6 months prior to consent * Previous local therapy for prostate cancer * Patients who have chemotherapy or radiotherapy for non-prostate cancer related treatment within 3 weeks prior to consent
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Failure-free survival (FFS) | At 2 years | Failure is defined as any one of the following events: PSA progression, clinical progression, radiographic progression, or death. The % of men who fail within 2 years of randomization will be compare between the two groups using a one-sided log-rank test. |
Secondary
| Measure | Time frame |
|---|---|
| Cancer-specific survival | Up to 2 years |
| Overall complication rate | Up to 2 years |
| Time to biochemical progression | Up to 2 years |
| Overall survival | Through study completion, a minimum of 4 years |
