Summary

This is a phase II multi-center study to determine the clinical impact of using a patient-specific genomic expression signature of androgen receptor (AR) activity to determine therapy for patients with castration-resistant metastatic prostate cancer (CRPC). After patient eligibility is determined, the genomic signature will be applied to fresh frozen tissue harvested from a metastatic lesion during image-guided biopsy. After assessing for androgen receptor activity, the investigators will select patients for either continued androgen manipulation with nilutamide (high AR activity) or targeted therapy with dasatinib (low AR activity). Once patients develop a first progression on either arm, patients will receive combination therapy with dasatinib and nilutamide. The primary aim is to estimate the median progression free survival in men with CRPC treated according to tumor AR activity. The investigators hypothesize that by treating men based upon AR activity, median progression free survival (PFS) will improve from a historical median of 3.0 months to 6.0 months.
