Study Endpoints
Primary Endpoints
Progression-free survival (PFS) of men with AVPC treated with 6 cycles of cabazitaxel + carboplatin followed by olaparib maintenance versus observation

Progression Free Survival (PFS) calculated as the time from randomization until any one of the following events occurs, whichever comes first: * Documented disease progression * Start of a new therapy in the absence of progression * Death in the absence of progression

Secondary Endpoints
Genomic alterations in DNA damage repair (DDR) pathway genes induced and/or selected by carboplatin and cabazitaxel chemotherapy [biopsy #2 vs biopsy #1]: Association with clinical outcome (PFS>6 months)
Up to one year
Rate of adverse events possibly, probably or definitely attributable to olaparib following cabazitaxel plus carboplatin in men with AVPC
Up to one year
Overall survival (OS) of men with AVPC treated with 6 cycles of cabazitaxel + carboplatin followed by olaparib maintenance vs observation
