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.
SIMCAP (Surgery in Metastatic Carcinoma of Prostate): Phase 2.5 Multi-Institution Randomized Prospective Clinical Trial Evaluating the Impact of Cytoreductive Radical Prostatectomy Combined With Best Systemic Therapy on Oncologic and Quality of Life Outcomes in Men With Newly Diagnosed Metastatic Prostate Cancer
PRIMARY OBJECTIVES:
- 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:
- 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
